13 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
15 Work around bug in CIFS and vboxsf file systems (Bug#13149).
16 The bug was observed on Ubuntu operating inside a virtual machine,
17 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
18 The workaround introduces a race condition on non-buggy hosts,
19 but it's an unlikely race and anyway there's a nearly identical
20 nearby race that can't be fixed.
21 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
23 (Fwrite_region): Test for file system time stamp bug.
24 (init_fileio): New function.

40 gap and end positions after each read and so help make_gap to work
41 properly. Do not signal an I/O error too early and so do not leave
42 not yet decoded characters in a buffer, which was the reason of
43 redisplay crash. Use list2 to build return value. Adjust comments.
45 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
47 Close a race when statting and reading files (Bug#13149).
48 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
49 This avoids a race if the file is renamed between stat and open.
50 This race is not the problem originally noted in Bug#13149;
51 see <http://bugs.gnu.org/13149#73> and later messages in the thread.

153 because we do not allocate extra memory any more. Add eassert.
154 * print.c (print_object): New code to print Lisp_Save_Value. Do not
155 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.

484 because the outer shadowed one has the same meaning.
485 * xterm.h (struct x_output): Remove toolbar_detached member since it's
487 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
488 (xg_create_tool_bar): Adjust users.
490 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
492 * buffer.h (BUF_COMPACT): New macro to follow the common style.
493 * buffer.c (Fget_buffer_create): Use it to set compact field of
494 struct buffer_text to avoid accessing an uninitialized value
495 when compact_buffer is called for the first time.
496 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
497 (Fset_buffer_modified_p): Use buffer_window_count to check
498 whether the buffer is displayed in some window.
499 * xdisp.c (message_dolog): Likewise.
501 2012-12-23 Eli Zaretskii <eliz@gnu.org>
503 * w32.c (acl_set_file): If setting the file security descriptor
504 fails, and the new DACL is identical to the existing one, silently
505 return success. This fixes problems for users backing up their
506 own files without having the necessary privileges for setting
507 security descriptors.
509 * w32proc.c (reader_thread): Do not index fd_info[] with negative
511 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
512 after WaitForSingleObject returns normally. This expedites reader
513 thread shutdown when delete_child triggers it.
514 (reap_subprocess): More accurate commentary for why we call
515 delete_child only when cp->fd is negative.
517 * w32.c (sys_close): Do not call delete_child on a subprocess
518 whose handle is not yet closed. Instead, set its file descriptor
519 to a negative value, so that reap_subprocess will call
520 delete_child on that subprocess when its SIGCHLD arrives.
521 This avoids closing handles used for communications between sys_select
522 and reader_thread, which doesn't give sys_select a chance to
523 notice that the process exited and invoke the SIGCHLD handler for
526 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
528 * nsfns.m (Fns_do_applescript): Run event loop until script has
529 been executed (Bug#12969).
530 (ns_run_ascript): Chech as_script for nil, set to nil after
533 2012-12-22 Martin Rudalics <rudalics@gmx.at>
535 * window.c (Fselect_window): Reword doc-string (Bug#13248).
537 2012-12-22 Eli Zaretskii <eliz@gnu.org>
539 * w32term.c (w32fullscreen_hook): New function.
540 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
542 2012-12-21 Eli Zaretskii <eliz@gnu.org>
544 * fileio.c (Finsert_file_contents): Doc fix.
546 * w32proc.c (new_child, delete_child, find_child_pid): For a
547 subprocess, consider its slot being in use as long as its process
548 handle (procinfo.hProcess) is not NULL. This avoids reusing the
549 slot when a new process is started immediately after killing
550 another one, without waiting enough time for the first process to
551 be reaped and resources allocated for it be orderly freed.
553 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
555 2012-12-21 Chong Yidong <cyd@gnu.org>
557 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
559 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
561 2012-12-21 Eli Zaretskii <eliz@gnu.org>
563 * w32.c (get_name_and_id): Always pass NULL as the first argument
564 of lookup_account_sid. Avoids crashes with UNC file names that
565 refer to DFS domains, not to specific machine names. (Bug#12621)
566 Remove now unused argument FNAME; all callers changed.
567 (get_file_owner_and_group): Remove now unused argument FNAME; all
570 2012-12-21 Chong Yidong <cyd@gnu.org>
572 * editfns.c (Finsert_char): Since read-char-by-name now signals an
573 error for invalid chars, don't check for a nil return value.
575 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
577 Avoid calls to CHAR_TO_BYTE if byte position is known.
578 * editfns.c (make_buffer_string_both): Use move_gap_both.
579 (Fbuffer_string): Use make_buffer_string_both.
580 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
582 (buf_bytepos_to_charpos): Likewise.
583 (charpos_to_bytepos): Remove.
584 * fileio.c (Finsert_file_contents): Use move_gap_both.
585 * search.c (Freplace_match): Likewise.
586 * process.c (process_send_region): Likewise. Use convenient
587 names for byte positions.
588 * lisp.h (charpos_to_bytepos): Remove prototype.
589 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
590 * insdel.c (move_gap): Likewise.
592 2012-12-20 Paul Eggert <eggert@cs.ucla.edu>
594 * xdisp.c (redisplay_internal): Remove now-unused local.
596 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
598 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
599 (redisplay_internal): Don't bother selecting the frame to get the
600 proper value of frame-local variables (bug#13225).
602 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
604 * textprop.c (set_text_properties_1): Do not allow NULL interval.
605 Rename 4th argument since it may be buffer or string. Adjust comment.
606 * intervals.c (graft_intervals_info_buffer): Find an interval here.
608 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
610 * coding.c (Fdetect_coding_region): Do not check start and end with
611 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
612 (code_convert_region): Likewise.
614 2012-12-18 Eli Zaretskii <eliz@gnu.org>
616 * w32.c (acl_get_file, acl_set_file): Run the file name through
617 map_w32_filename, and resolve any symlinks in the file name, like
619 (acl_set_file): Call revert_to_self, if any privileges were
622 2012-12-17 Juanma Barranquero <lekktu@gmail.com>

625 ($(BLD)/w32.$(O)): Update dependencies.
627 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
629 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
630 propagate redisplay's scrolling (if any) to the right window.
631 (redisplay_internal): Use ensure_selected_frame.
632 (display_mode_lines): Complete last fix.
633 * window.c (select_window_1): New func, extracted from select_window.
634 (select_window): Use it.
635 * window.h (select_window_1): Declare.
637 2012-12-17 Eli Zaretskii <eliz@gnu.org>
639 Emulate Posix ACL APIs on MS-Windows.
640 * w32.c: Include sddl.h and sys/acl.h.
641 (SDDL_REVISION_1): Define if not already defined.

659 * fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.
661 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
663 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
664 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
665 for some of that bug's symptoms can now cause Emacs to abort.
666 Remove the workaround.
667 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
668 The bug that caused SIGCHLD to get lost has been fixed, and the
669 workaround for it can now cause Emacs to abort.
671 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
673 * sysdep.c (emacs_abort): Bump backtrace size to 40.
674 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
675 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
677 2012-12-16 Romain Francoise <romain@orebokech.com>
679 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
680 (Fcopy_file): Change last arg to `preserve_extended_attributes'
681 and copy ACL entries of file in addition to SELinux context if set.
682 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
684 * Makefile.in (LIBACL_LIBS): New macro.
687 2012-12-15 Paul Eggert <eggert@cs.ucla.edu>
689 * fileio.c (internal_delete_file): Use bool for boolean.
691 2012-12-15 Eli Zaretskii <eliz@gnu.org>
693 Fix bug #13079 on MS-Windows with temp files not being deleted.
694 * w32.h (_child_process): New members input_file and
696 (register_child): First argument is now pid_t.
697 (record_infile, record_pending_deletion): New prototypes.
699 * w32proc.c (new_child): Initialize input_file and
700 pending_deletion members of the child.
701 (delete_child): Delete the child's temporary input file, if any,
702 that is pending deletion.
703 (register_child): First argument is now pid_t.
704 (record_infile, record_pending_deletion): New functions.
705 (reap_subprocess): Fix a typo in DebPrint string.
706 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
708 * fileio.c (internal_delete_file): Return an int again: non-zero
709 if delete-file succeeds, zero otherwise.
711 * lisp.h (internal_delete_file): Adjust prototype.
713 * callproc.c (Fcall_process): Don't overwrite infile with result
715 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
716 asynchronous subprocess, record the name of the input file name,
718 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
719 delete the file, record it as pending deletion when the subprocess
722 2012-12-14 Eli Zaretskii <eliz@gnu.org>
724 * editfns.c [HAVE_PWD_H]: Include grp.h.
726 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.
728 2012-12-14 Paul Eggert <eggert@cs.ucla.edu>
730 Fix permissions bugs with setgid directories etc. (Bug#13125)
731 * dired.c (Ffile_attributes): Return t as the 9th attribute,
732 to mark it as a placeholder. The old value was often wrong.
733 The only user of this attribute has been changed to use
734 file-ownership-preserved-p instead, with its new group arg.
735 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.

742 2012-12-14 Eli Zaretskii <eliz@gnu.org>
744 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
745 try to get accurate owner and group information from NT file
746 security APIs. This is to make most callers of 'stat' and
747 'lstat', which don't need that information, much faster.
749 * dired.c (Ffile_attributes) [WINDOWSNT]:
750 Set w32_stat_get_owner_group to a non-zero value, to request accurate
751 owner and group information from 'lstat'.
753 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
755 * fileio.c (Finsert_file_contents): Don't put tail into head area,
756 as that confuses set-auto-coding, so insist on the head-read
757 returning the full 1024 bytes. Let lseek compute the tail offset;
758 less work for us. Do not ignore I/O errors when reading the tail.
760 * xdisp.c: Minor style fixes.
761 (init_iterator): Hoist assignment out of if-expression.
762 (markpos_of_region): Callers now test for sign, not for -1.

769 (redisplay_window): Check whether the region is of non-zero length.
770 (try_cursor_movement): Allow if the region length is zero.

779 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
781 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
782 files, fixing a regression from 24.2.
783 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
785 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
787 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
788 fstat shouldn't fail, and if it does fail copy-file should not proceed.
789 Remove unnecessary S_ISLNK test, as (contra the comments) this
790 function can't copy symlinks. Improve quality of error message
791 when attempting to copy files that are neither regular files nor
794 2012-12-12 Dmitry Antipov <dmantipov@yandex.ru>
796 * dispnew.c (set_window_cursor_after_update): Use clip_to_bounds.

800 * xterm.c (x_set_toolkit_scroll_bar_thumb): Likewise.
802 2012-12-12 Daniel Colascione <dancol@dancol.org>
804 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
805 the dumped Emacs is not a sparse file, greatly improving Cygwin
806 "make bootstrap" performance.
808 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
810 * inotify.c (inotify_callback): Generate an Emacs event for every
811 incoming inotify event.
813 2012-12-11 Eli Zaretskii <eliz@gnu.org>
815 * xdisp.c (handle_face_prop): Fix logic of computing
816 it->start_of_box_run_p.
817 (append_space_for_newline): If the glyph row is R2L, reset the
818 iterator's end_of_box_run_p flag before prepending the space glyph.
819 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
820 iterator's start_of_box_run_p flag before prepending the stretch.
821 (append_glyph, produce_image_glyph, append_composite_glyph)
822 (append_stretch_glyph, append_glyphless_glyph): Reverse the
823 left_box_line_p and right_box_line_p flags of the glyph for R2L
824 glyph rows. (Bug#13011)
826 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
828 * buffer.c (Fset_buffer_multibyte): Do not force redisplay
829 if changed buffer is not shown in a window.

831 * window.c (replace_buffer_in_windows_safely): Do nothing
832 if buffer is not shown in a window.
833 (Fforce_window_update): Likewise if string or buffer argument
836 2012-12-11 Eli Zaretskii <eliz@gnu.org>
838 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
839 encoded_file_name, which is what it is.
841 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
843 Consistently use marker_position and marker_byte_position.

864 * w32term.c, keyboard.c: Fix build break in cygw32 by omitting
865 Windows file notification functionality unless WINDOWSNT.
867 * w32gui.h (hprevinst, lpCmdLine, nCmdShow): Remove unused
870 * w32fns.c (cache_system_info): Initialize the global hinst
871 variable here so various initialization calls DTRT.
873 * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused variables.
874 (hinst): Remove unneeded extern declaration.
875 (_start): Remove initialization of above variables; remove
876 initialization of hinst, as cache_system_info now does that.
878 * emacs.c (main): Call cache_system_info early in startup; we
879 previously weren't calling it in Cygwin builds.
881 * Makefile.in (ntsource, WINDRES, W32_RES, W#@_RES_LINK):
882 Teach the autoconf build system how to compile a Windows resource file

989 * w32fns.c (cache_system_info): Cast sysinfo_cache.dwPageSize to
990 DWORD_PTR, for compatibility with 64-bit builds.
992 * w32.c (_PROCESS_MEMORY_COUNTERS_EX):
993 (GetProcessWorkingSetSize_Proc, get_process_working_set_size)
994 (system_process_attributes): Use SIZE_T rather than DWORD, for
995 compatibility with 64-bit builds.
997 2012-12-10 Christopher Schmidt <christopher@ch.ristopher.com>
999 * lread.c (Vload_source_file_function): Doc fix (Bug#11647).
1001 2012-12-10 Eli Zaretskii <eliz@gnu.org>
1003 * indent.c (Fvertical_motion): If a display string will be
1004 displayed on the left or the right margin, don't consider it as a
1005 factor in cursor positioning. (Bug#13108)
1007 2012-12-10 Martin Rudalics <rudalics@gmx.at>
1009 * editfns.c (Fcompare_buffer_substrings): Reword doc-string.
1011 2012-12-10 Paul Eggert <eggert@cs.ucla.edu>
1013 * fileio.c (Fsubstitute_in_file_name): Use ptrdiff_t, not int,
1016 2012-12-08 Eli Zaretskii <eliz@gnu.org>
1018 * w32.c (unsetenv): Return 0 if the input string is too long.
1020 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
1022 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).
1023 * alloc.c (xputenv): New function.
1024 * dbusbind.c (Fdbus_init_bus):
1026 * xterm.c (x_term_init):
1027 Use xputenv instead of setenv or putenv, to detect memory exhaustion.
1028 * editfns.c (initial_tz): Move static var decl up.
1029 (tzvalbuf_in_environ): New static var.
1030 (init_editfns): Initialize these two static vars.
1031 (Fencode_time): Don't assume arbitrary limit on EMACS_INT width.
1032 Save old TZ value on stack, if it's small.
1033 (Fencode_time, set_time_zone_rule): Don't modify 'environ' directly;
1034 instead, use xputenv+unsetenv to set and restore TZ.
1035 (environbuf): Remove static var. All uses removed.
1036 (Fset_time_zone_rule): Do not save TZ and environ;
1037 no longer needed here.
1038 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
1039 Move to inside set_time_zone_rule; they don't need file scope any more.
1040 (set_time_zone_rule): Maintain the TZ=value string separately.
1041 (syms_of_editfns): Don't initialize initial_tz;
1042 init_editfns now does it.
1043 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
1044 * lisp.h (xputenv): New decl.
1046 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
1048 * w32fns.c (emacs_abort): Don't do arithmetics on void pointers.
1050 2012-12-08 Eli Zaretskii <eliz@gnu.org>
1052 * w32.c (unsetenv, sys_putenv): New functions.
1054 2012-12-08 Chong Yidong <cyd@gnu.org>
1056 * editfns.c (Finsert_char): Make the error message more
1057 informative (Bug#12992).
1059 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
1061 Simplify get_lim_data.
1062 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
1063 Remove USG and vlimit methods; no longer used these days.
1064 Add #error catchall just in case.
1066 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
1067 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
1068 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
1069 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
1070 (deleted_pid_list, Fdelete_process, create_process)
1071 (record_child_status_change, handle_child_signal, deliver_child_signal)
1072 (init_process_emacs, syms_of_process):
1073 Assume SIGCHLD is defined.
1074 (parse_signal): Remove. All uses removed.
1075 (abbr_to_signal): New static function.
1076 (Fsignal_process): Use it to convert signal names to ints.
1077 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
1078 kill (getpgrp (), ...).
1079 (emacs_sigaction_init): Assume SIGCHLD is defined.
1080 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,
1081 SIGPIPE, and SIGQUIT are defined. Do not worry about SIGCLD any more.
1082 * syssignal.h (EMACS_KILLPG): Remove.
1083 All uses replaced by 'kill' with a negative pid.
1084 (SIGCHLD): Remove definition, as we now assume SIGCHLD.
1085 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
1087 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
1089 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
1090 This will cause a production Emacs to dump core instead of
1093 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1095 * frame.c (make_frame): Do not set window's buffer to t.
1096 * window.c (Fsplit_window_internal): Likewise. Previously it was
1097 used to indicate that the window is being set up. Now we use
1098 set_window_buffer for all new windows, so the condition in ...
1099 (Fset_window_buffer): ... is always true and can be removed.
1101 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1103 Convenient macro to check whether the buffer is hidden.
1104 * buffer.h (BUFFER_HIDDEN_P): New macro.
1105 * frame.c (make_frame): Use it. Adjust comment.
1106 * buffer.c (candidate_buffer): New function.
1107 (Fother_buffer, other_buffer_safely): Use it.
1109 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1111 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
1112 if the child process is still running. Instead, exit the wait
1113 loop and return zero. (Bug#13086)
1115 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1117 * frame.h (x_char_width, x_char_height): Remove prototypes.
1118 * w32term.h (x_char_width, x_char_height): Likewise.
1119 * xfns.c (x_char_width, x_char_height): Remove.
1120 * w32fns.c (x_char_width, x_char_height): Likewise.
1121 * nsfns.c (x_char_width, x_char_height): Likewise.
1122 * frame.c (Fframe_char_width): Use FRAME_COLUMN_WIDTH for

1128 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
1130 Fix a recently-introduced delete-process race condition.
1131 * callproc.c, process.h (record_kill_process):
1132 New function, containing part of the old call_process_kill.
1133 (call_process_kill): Use it.
1134 This does not change call_process_kill's behavior.
1135 * process.c (Fdelete_process): Use record_kill_process to fix a
1136 race condition that could cause Emacs to lose track of a child.
1138 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1140 Avoid code duplication between prev_frame and next_frame.
1141 * frame.c (candidate_frame): New function. Add comment.
1142 (prev_frame, next_frame): Use it. Adjust comment.
1144 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1146 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
1147 fails, signal an error instead of continuing with an empty
1149 Encode expanded temp file pattern before passing it to mkstemp or
1152 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
1153 Encode the file name before passing it to dostounix_filename, in
1154 case it will downcase it (under w32-downcase-file-names).
1157 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
1159 Minor call-process cleanups.
1160 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
1161 at the same time as other platforms, to simplify analysis.
1162 No need for fd0_volatile since we have synch_process_fd.
1163 Avoid needless emacs_close; arg is always negative.
1165 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
1167 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
1170 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
1172 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
1173 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
1174 and mouse_face_hidden members to a bitfields.
1175 * frame.h (struct frame): Remove set-but-not-used space_width member.
1176 (FRAME_SPACE_WIDTH): Remove.
1177 * nsterm.m, w32term.c, xterm.c: Adjust users.
1178 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
1179 member. Adjust users. Convert term_initted, delete_in_insert_mode,
1180 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
1181 members to a bitfields.
1183 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
1185 Don't let call-process be a zombie factory (Bug#12980).
1186 Fixing this bug required some cleanup of the signal-handling code.
1187 As a side effect, this change also fixes a longstanding rare race
1188 condition whereby Emacs could mistakenly kill unrelated processes,
1189 and it fixes a bug where a second C-g does not kill a recalcitrant
1190 synchronous process in GNU/Linux and similar platforms.
1191 The patch should also fix the last vestiges of Bug#9488,
1192 a bug which has mostly been fixed on the trunk by other changes.
1193 * callproc.c, process.h (synch_process_alive, synch_process_death)
1194 (synch_process_termsig, sync_process_retcode):
1195 Remove. All uses removed, to simplify analysis and so that
1196 less consing is done inside critical sections.
1197 * callproc.c (call_process_exited): Remove. All uses replaced
1198 with !synch_process_pid.
1199 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
1200 These take the role of what used to be in unwind-protect arg.
1202 (block_child_signal, unblock_child_signal):
1203 New functions, to avoid races that could kill innocent-victim processes.
1204 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
1205 (call_process_kill): Record killed processes as deleted, so that
1206 zombies do not clutter up the system. Do this inside a critical
1207 section, to avoid a race that would allow the clutter.
1208 (call_process_cleanup): Fix code so that the second C-g works again
1209 on common platforms such as GNU/Linux.
1210 (Fcall_process): Create the child process in a critical section,
1211 to fix a race condition. If creating an asynchronous process,
1212 record it as deleted so that zombies do not clutter up the system.
1213 Do unwind-protect for WINDOWSNT too, as that's simpler in the
1214 light of these changes. Omit unnecessary call to emacs_close
1215 before failure, as the unwind-protect code does that.
1216 * callproc.c (call_process_cleanup):
1217 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
1218 * process.c (record_deleted_pid): New function, containing
1219 code refactored out of Fdelete_process.
1220 (Fdelete_process): Use it.
1221 (process_status_retrieved): Remove. All callers changed to use
1222 child_status_change.
1223 (record_child_status_change): Remove, folding its contents into ...
1224 (handle_child_signal): ... this signal handler. Now, this
1225 function is purely a handler for SIGCHLD, and is not called after
1226 a synchronous waitpid returns; the synchronous code is moved to
1227 wait_for_termination. There is no need to worry about reaping
1228 more than one child now.
1229 * sysdep.c (get_child_status, child_status_changed): New functions.
1230 (wait_for_termination): Now takes int * status and bool
1231 interruptible arguments, too. Do not record child status change;
1232 that's now the caller's responsibility. All callers changed.
1233 Reimplement in terms of get_child_status.
1234 (wait_for_termination_1, interruptible_wait_for_termination):
1235 Remove. All callers changed to use wait_for_termination.
1236 * syswait.h: Include <stdbool.h>, for bool.
1237 (record_child_status_change, interruptible_wait_for_termination):
1239 (record_deleted_pid, child_status_changed): New decls.
1240 (wait_for_termination): Adjust to API changes noted above.
1242 * bytecode.c, lisp.h (Qbytecode): Remove.
1243 No longer needed after 2012-11-20 interactive-p changes.
1245 2012-12-03 Eli Zaretskii <eliz@gnu.org>
1247 * xdisp.c (redisplay_window): If the cursor is visible, but inside
1248 the scroll margin, move point outside the margin. (Bug#13055)
1250 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
1252 * gtkutil.c (my_log_handler): New function.
1253 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
1255 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1257 * lisp.h (modify_region): Rename to...
1258 (modify_region_1): ...new prototype.
1259 * textprop.c (modify_region): Now static. Adjust users.
1260 * insdel.c (modify_region): Rename to...
1261 (modify_region_1): ...new function to work with current buffer.
1262 Adjust comment and users. Use true and false for booleans.
1264 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1266 * alloc.c (free_save_value): New function.
1267 (safe_alloca_unwind): Use it.
1268 * lisp.h (free_save_value): New prototype.
1269 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
1271 (save_excursion_restore): Adjust to match saved data structure.
1272 Use free_save_value to offload some work from GC. Drop obsolete
1275 2012-12-03 Chong Yidong <cyd@gnu.org>
1277 * fileio.c (Vauto_save_list_file_name): Doc fix.
1279 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
1281 * w32fns.c: Remove prototype of atof.
1282 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
1284 (file_dialog_callback): Make it UINT_PTR.
1286 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
1289 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1290 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
1293 2012-12-03 Glenn Morris <rgm@gnu.org>
1295 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
1297 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
1299 Fix xpalloc confusion after memory is exhausted.
1300 * alloc.c (xpalloc): Comment fix.
1301 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
1302 and signals an error, do not clear charset_table_size, as
1303 charset_table is still valid.
1304 * doprnt.c (evxprintf): Clear *BUF after freeing it.
1306 Use execve to avoid need to munge environ (Bug#13054).
1307 * callproc.c (Fcall_process):
1308 * process.c (create_process):
1309 Don't save and restore environ; no longer needed.
1310 * callproc.c (child_setup):
1311 Use execve, not execvp, to preserve environ.
1313 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
1315 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
1317 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1319 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
1320 display for sliced images (Bug#10500).
1322 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
1324 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
1326 * doc.c (Fdocumentation): Re-add handling of function-documentation,
1327 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
1329 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
1331 * xdisp.c (window_outdated): Remove eassert since it hits
1332 some suspicious corner cases (see Bug#13007 and Bug#13012).
1333 (mode_line_update_needed): New function.
1334 (redisplay_internal, redisplay_window): Use it.
1335 (ensure_selected_frame): New function.
1336 (redisplay_internal, unwind_redisplay): Use it.
1337 (redisplay_internal): Move comment about buffer_shared...
1338 (buffer_shared_and_changed): ...near to its real use.
1340 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
1342 * callproc.c (Fcall_process): Don't misreport vfork failure.
1344 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
1346 * callproc.c (Fcall_process): Fix vfork portability problems.
1347 Do not assume that fd[0], count, filefd, and save_environ survive
1348 vfork. Fix bug whereby wrong errno value could be reported for
1349 pipe failure. Some minor cleanups, too, as follows. Move buf and
1350 bufsize to the context where they're needed. Change new_argv to
1351 be of type char **, as this is more convenient and avoids casts.
1352 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
1353 Now local constants, not macros.
1355 2012-11-18 Kenichi Handa <handa@gnu.org>
1357 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
1358 for the variable "f".
1360 2012-11-13 Kenichi Handa <handa@gnu.org>
1362 * font.c (font_unparse_xlfd): Exclude special characters from the
1363 generating XLFD name.
1365 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
1367 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.
1368 * dired.c (stat_uname, stat_gname):
1369 * fileio.c (Fexpand_file_name): Remove no-longer-needed casts.
1371 Assume POSIX 1003.1-1988 or later for errno.h (Bug#12968).

1373 Assume EAGAIN and EINTR are defined.
1375 * fileio.c (Fcopy_file): Assume EISDIR is defined.
1376 * gmalloc.c (ENOMEM, EINVAL): Assume they're defined.
1377 * gnutls.c (emacs_gnutls_write): Assume EAGAIN is defined.
1378 * lread.c (readbyte_from_file): Assume EINTR is defined.
1379 * process.c (wait_reading_process_output, send_process) [subprocesses]:
1380 Assume EIO and EAGAIN are defined.
1381 * unexcoff.c (write_segment): Assume EFAULT is defined.
1383 2012-11-27 Eli Zaretskii <eliz@gnu.org>
1385 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
1388 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
1389 highlighting on the frame was cleared. Prevents assertion
1390 violations when repeatedly clicking on the "Top" link of the
1391 "bread-crumbs" in Info buffers.
1393 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>
1395 * sysdep.c (sys_subshell): Don't assume pid_t fits in int.
1397 2012-11-24 Ken Brown <kbrown@cornell.edu>
1399 * keyboard.c (HAVE_MOUSE):
1400 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
1401 were always defined.
1403 2012-11-24 Eli Zaretskii <eliz@gnu.org>
1405 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
1406 between bpos_covered and bpos_max. This fixes cursor display when
1407 several display strings follow each other.
1409 * .gdbinit (pgx): If the glyph's object is a string, display the
1410 pointer to string data, rather than the value of the string object
1411 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
1413 * indent.c (Fvertical_motion): If the starting position is covered
1414 by a display string, return to one position before that, to avoid
1415 overshooting it inside move_it_to. (Bug#12930)
1417 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
1419 * frame.h (struct frame): Remove display_preempted member
1420 since all users are dead long ago.

1422 * w32menu.c (pending_menu_activation): Remove since not
1424 (set_frame_menubar): Adjust user.
1425 * w32term.h (struct x_output): Drop outdated #if 0 code.
1426 (struct w32_output): Use bitfields for explicit_parent,
1427 asked_for_visible and menubar_active members.
1428 Drop unused pending_menu_activation member.
1429 * xterm.h (struct x_output): Drop outdated #if 0 code.
1430 Use bitfields for explicit_parent, asked_for_visible,
1431 has_been_visible and net_wm_state_hidden_seen members.
1433 2012-11-23 Eli Zaretskii <eliz@gnu.org>
1435 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
1436 of a literal "/". (Bug#12955)
1437 (gl-stamp): Invoke fc.exe directly, not through cmd.
1439 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
1441 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
1442 * dired.c: Assume HAVE_DIRENT_H.
1443 (NAMLEN): Remove, replacing with ...
1444 (dirent_namelen): New function. All uses changed. Use the GNU macro
1445 _D_EXACT_NAMELEN if available, as it's faster than strlen.
1446 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
1447 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
1448 * makefile.w32-in (DIR_H): Remove. All uses replaced with
1450 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
1451 * ndir.h: Rename to ../nt/inc/dirent.h.
1452 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
1453 Do not include <dirent.h>; no longer needed.
1454 * w32.c: Include <dirent.h> rather than "ndir.h".
1456 2012-11-23 Chong Yidong <cyd@gnu.org>
1458 * xftfont.c (xftfont_open): Remove duplicate assignment.
1460 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
1462 * alloc.c (Fgarbage_collect): Unblock input after clearing
1463 gc_in_progress to avoid note_mouse_highlight glitch with GC.
1464 * frame.h (FRAME_MOUSE_UPDATE): New macro.
1465 * msdos.c (IT_frame_up_to_date): Use it here...
1466 * w32term.c (w32_frame_up_to_date): ...here...
1467 * xterm.c (XTframe_up_to_date): ...and here...
1468 * nsterm.m (ns_frame_up_to_date): ...but not here.
1469 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
1471 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
1472 Do not check whether GC is in progress.
1474 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
1476 * xdisp.c (window_buffer_changed): New function.
1477 (update_menu_bar, update_tool_bar): Use it to
1478 simplify large 'if' statements.
1479 (redisplay_internal): Generalize commonly used
1480 'tail' and 'frame' local variables.
1482 2012-11-22 Eli Zaretskii <eliz@gnu.org>
1484 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
1485 with Windows system header.
1487 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
1489 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
1490 * alloc.c: Assume unistd.h exists.
1491 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
1492 * sysdep.c (get_current_dir_name): Assume getcwd exists.
1493 (getwd) [USG]: Remove; no longer needed.
1494 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
1495 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
1496 * w32.h (getcwd): Remove decl.
1498 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
1500 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
1501 Make it set selected_window as well.
1502 (update_tool_bar): Use it.
1504 2012-11-21 Ken Brown <kbrown@cornell.edu>
1506 * emacs.c (main): Set the G_SLICE environment variable for all
1507 Cygwin builds, not just GTK builds. See
1508 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
1510 2012-11-21 Eli Zaretskii <eliz@gnu.org>
1512 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1513 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
1514 Define for the MSVC compiler.
1516 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
1518 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
1519 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
1520 dostounix_filename. Prevents crashes down the road, because
1521 dostounix_filename assumes it gets a unibyte string.
1522 Reported by Michel de Ruiter <michel@sentient.nl>, see
1523 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
1525 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>

1529 * lread.c (init_obarray): Set `function' fields to Qnil.
1530 * eval.c (Fcommandp): Ignore Qunbound.
1531 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
1532 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
1533 Test NILP rather than Qunbound.
1534 (Ffmakunbound): Set to Qnil.
1535 (Fsymbol_function): Never signal an error.
1536 (Finteractive_form): Ignore Qunbound.
1538 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
1540 * eval.c (interactive_p): Remove no-longer-used decl.
1542 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
1544 * xdisp.c (buffer_shared): Adjust comment.
1545 (buffer_shared_and_changed): New function.
1546 (prepare_menu_bars, redisplay_internal): Use it to
1547 decide whether all windows or frames should be updated.
1548 (window_outdated): New function.
1549 (text_outside_line_unchanged_p, redisplay_window): Use it.
1550 (redisplay_internal): Likewise. Fix indentation.
1552 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
1554 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
1555 (syms_of_eval): Remove corresponding defsubr.
1556 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
1558 2012-11-19 Daniel Colascione <dancol@dancol.org>
1560 * w32fns.c (Fx_file_dialog):
1561 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
1562 cygwin_convert_file_name*.
1564 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
1565 Rename cygwin_convert_path* to cygwin_convert_file_name*.
1567 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
1569 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
1571 2012-11-18 Eli Zaretskii <eliz@gnu.org>
1573 * w32select.c: Include w32common.h before w32term.h, so that
1574 windows.h gets included before w32term.h uses some of its
1575 features, see below.
1577 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
1579 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
1581 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
1583 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
1585 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
1586 (ns_select): Return at once if events are held (Bug#12834).
1588 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
1590 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
1591 Needed following 2012-10-20 change. (Bug#12902)
1593 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
1595 * w32proc.c (waitpid): Remove unused label get_result.
1597 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
1599 * makefile.w32-in (SYSWAIT_H): New macro.
1600 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
1601 ($(BLD)/sysdep.$(O)): Update dependencies.
1603 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
1605 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
1606 * callproc.c (relocate_fd): Assume F_DUPFD.
1607 * emacs.c, term.c (O_RDWR): Remove.
1608 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
1609 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
1610 * nsterm.m: Assume <fcntl.h> exists.
1611 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
1612 (create_pty, Fmake_network_process, server_accept_connection)
1613 (wait_reading_process_output, init_process_emacs):
1615 (wait_reading_process_output): Put in a special case for WINDOWSNT
1616 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
1617 It's not clear this is needed, but it's a more-conservative change.
1618 (create_process): Assume FD_CLOEXEC.
1619 (create_process, create_pty): Assume O_NOCTTY.
1620 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
1621 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
1622 Omit if not DOS_NT, since F_GETFL is not defined there.
1623 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
1624 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
1626 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
1627 lack it, since gnulib guarantees this.
1628 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
1630 2012-11-17 Eli Zaretskii <eliz@gnu.org>
1632 * w32.c (faccessat): Pretend that directories have the execute bit
1633 set. Emacs expects that, e.g., in files.el:cd-absolute.
1635 * w32proc.c (create_child): Don't clip the PID of the child
1636 process to fit into an Emacs integer, as this is no longer a
1638 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
1639 reaping only the process specified by PID argument, if that is
1640 positive. Use PID instead of dead_child to know which process to
1641 reap. Wait for the child to die only if WNOHANG is not in
1643 (sys_select): Don't set dead_child.
1645 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
1646 as it is no longer needed.
1648 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
1650 (record_child_status_change): Remove the setting of
1651 record_at_most_one_child for the !WNOHANG case.
1653 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
1655 Fix problems in ns port found by static checking.
1656 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
1657 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
1658 not to process group.
1659 (ns_select): Use emacs_write, not write, as that's more robust
1660 in the presence of signals.
1661 (fd_handler:): Check for read errors.
1663 2012-11-16 Glenn Morris <rgm@gnu.org>
1665 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
1667 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
1669 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
1671 2012-11-16 Eli Zaretskii <eliz@gnu.org>
1673 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
1674 use the same value of thread handle.
1675 (start_timer_thread): If the timer thread exited (due to error),
1676 clean up by closing the two handles it used. Duplicate the caller
1677 thread's handle here, so it gets duplicated only once, when
1678 launching the timer thread. Set priority of the timer thread, not
1680 (getitimer): Don't duplicate the caller thread's handle here.
1683 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
1685 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
1688 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
1690 Remove no-longer-used pty_max_bytes variable.
1691 * process.c (pty_max_bytes): Remove; unused.
1692 (send_process): Do not set it.
1694 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
1696 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
1697 Update dependencies.
1699 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
1701 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
1702 This follows up on the 2012-09-29 patch that removed indirection
1703 for the 'function' field. Reported by Sergey Vinokurov in
1704 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
1706 2012-11-14 Eli Zaretskii <eliz@gnu.org>
1708 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
1709 different name, as the MS runtime does not have such a function,
1710 and probably never will.) All callers changed. Ignore DIRFD
1711 value if PATH is an absolute file name, to match Posix spec
1712 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
1715 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
1717 * xdisp.c (echo_area_display, redisplay_internal):
1718 Omit redundant check whether frame_garbaged is set.
1720 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
1722 Use faccessat, not access, when checking file permissions (Bug#12632).
1723 This fixes a bug that has been present in Emacs since its creation.
1724 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
1725 which must set some sort of record. (Torek's bug report was against
1726 a predecessor of GNU Emacs, but GNU Emacs happened to have the
1727 same common flaw.) See Torek's Usenet posting
1728 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
1729 Posted: Fri Apr 8 14:18:56 1983.
1730 * Makefile.in (LIB_EACCESS): New macro.
1732 * callproc.c (init_callproc):
1733 * charset.c (init_charset):
1734 * fileio.c (check_existing, check_executable, check_writable)
1736 * lread.c (openp, load_path_check):
1737 * process.c (allocate_pty):
1739 Use effective UID when checking permissions, not real UID.
1740 * callproc.c (init_callproc):
1741 * charset.c (init_charset):
1742 * lread.c (load_path_check, init_lread):
1743 Test whether directories are accessible, not merely whether they exist.
1744 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
1745 * fileio.c (check_existing, check_executable, check_writable)
1747 Use symbolic names instead of integers for the flags, as they're
1749 (check_writable): New arg AMODE. All uses changed.
1750 Set errno on failure.
1751 (Ffile_readable_p): Use faccessat, not stat + open + close.
1752 (Ffile_writable_p): No need to call check_existing + check_writable.
1753 Just call check_writable and then look at errno. This saves a syscall.
1754 dir should never be nil; replace an unnecessary runtime check
1755 with an eassert. When checking the parent directory of a nonexistent
1756 file, check that the directory is searchable as well as writable, as
1757 we can't create files in unsearchable directories.
1758 (file_directory_p): New function, which uses 'stat' on most platforms
1759 but faccessat with D_OK (for efficiency) if WINDOWSNT.
1760 (Ffile_directory_p, Fset_file_times): Use it.
1761 (file_accessible_directory_p): New function, which uses a single
1762 syscall for efficiency.
1763 (Ffile_accessible_directory_p): Use it.
1764 * xrdb.c (file_p): Use file_directory_p.
1765 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
1766 * lread.c (openp): When opening a file, use fstat rather than
1767 stat, as that avoids a permissions race. When not opening a file,
1768 use file_directory_p rather than stat.
1769 (dir_warning): First arg is now a usage string, not a format.
1770 Use errno. All uses changed.
1771 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
1772 that merely introduced a race.
1773 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
1774 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
1775 and similarly for the other O_* flags.
1776 * w32.c (sys_faccessat): Rename from sys_access and switch to
1777 faccessat's API. All uses changed.
1778 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
1779 (magic_db): Rename from magic_file_p.
1780 (magic_db, search_magic_path): Return an XrmDatabase rather than a
1781 char *, so that we don't have to test for file existence
1782 separately from opening the file for reading. This removes a race
1783 fixes a permission-checking problem, and simplifies the code.
1785 (file_p): Remove; no longer needed.
1787 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
1789 Omit glyphs initialization at startup.
1790 * dispnew.c (glyphs_initialized_initially_p): Remove.
1791 (adjust_frame_glyphs_initially): Likewise. Adjust users.
1792 (Fredraw_frame): Move actual code from here...
1793 (redraw_frame): ...to here. Add eassert. Adjust comment.
1794 (Fredraw_display): Use redraw_frame.
1795 * xdisp.c (clear_garbaged_frames): Likewise.
1797 2012-11-13 Eli Zaretskii <eliz@gnu.org>
1799 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
1800 passed to pint2str and pint2hrstr to be at most the size of the
1801 frame's decode_mode_spec_buffer. This avoids crashes with very
1802 large values of FIELD_WIDTH argument to decode_mode_spec.
1805 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
1807 Fix a race with verify-visited-file-modtime (Bug#12863).
1808 Since at least 1991 Emacs has ignored an mtime difference of no
1809 more than one second, but my guess is that this was to work around
1810 file system bugs that were fixed long ago. Since the race is
1811 causing problems now, let's remove that code.
1812 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
1813 whose time stamp is off by no more than a second. Insist that the
1814 file time stamps match exactly.
1816 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1818 * frame.h (struct frame): Convert external_tool_bar member to
1819 1-bit unsigned bitfield.
1820 * termhooks.h (struct terminal): Remove mouse_moved member since
1821 all users are long dead. Adjust comment on mouse_position_hook.
1823 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1825 Simplify by using FOR_EACH_FRAME here and there.
1826 * frame.c (next_frame, prev_frame, other_visible_frames)
1827 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
1828 * w32term.c (x_window_to_scroll_bar): Likewise.
1829 * window.c (window_list): Likewise.
1830 * xdisp.c (x_consider_frame_title): Likewise.
1831 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
1832 * xfns.c (x_window_to_frame, x_any_window_to_frame)
1833 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
1834 * xmenu.c (menubar_id_to_frame): Likewise.
1835 * xselect.c (frame_for_x_selection): Likewise.
1836 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
1837 (x_window_to_menu_bar): Likewise.
1838 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
1840 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
1842 * data.c (Qdefalias_fset_function): Now static.
1844 Another tweak to vectorlike_header change.
1845 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
1846 Remove, and replace all uses with ...
1847 (next_in_free_list, set_next_in_free_list):
1848 New functions, which respect C's aliasing rules better.
1850 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
1852 * window.c (list4i): Rename from 'quad'. All uses changed.
1853 Needed because <sys/types.h> defines 'quad' on Solaris 10.
1855 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
1857 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
1858 warning about mixing declarations and code in ISO C90.
1860 2012-11-10 Martin Rudalics <rudalics@gmx.at>
1862 * window.c (Fsplit_window_internal): Set combination limit of
1863 new parent window to t iff Vwindow_combination_limit is t;
1864 fixing a regression introduced with the change from 2012-09-22.
1865 (Fset_window_combination_limit): Fix doc-string.
1867 2012-11-10 Eli Zaretskii <eliz@gnu.org>
1869 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
1870 amount when the scroll margins are too large. When scrolling
1871 backwards in the buffer, give up if cannot reach point or the
1872 scroll margin within a reasonable number of screen lines.
1873 Fixes point position in window under scroll-up/down-aggressively when
1874 point is positioned many lines beyond the window top/bottom.
1877 * ralloc.c (relinquish): If real_morecore fails to return memory
1878 to the system, don't crash; instead, leave the last heap
1879 unchanged and return. (Bug#12774)
1881 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1883 * lisp.h (AUTOLOADP): New macro.
1884 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
1885 * data.c (Ffset): Remove special ad-advice-info handling.
1886 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
1888 (Finteractive_form): Simplify.
1889 (Fquo): Don't insist on having at least 2 arguments.
1890 (Qdefalias_fset_function): New var.
1892 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>

1909 Tweak last vectorlike_header change.
1910 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
1911 vectorlike object on the free list. This is introduced to avoid
1912 some (but not all) pointer casting and aliasing problems, see
1913 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
1914 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike

1946 special hash function containing a comparison that always yields 1.
1948 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1950 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
1951 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
1952 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
1955 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
1957 * image.c (xpm_make_color_table_h): Fix compiler error because
1958 make_hash_table changed.

1962 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
1964 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1966 Use ad-hoc comparison function for the profiler's hash-tables.
1967 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
1968 (make_log): Use them.

1979 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
1980 (hash_lookup, hash_remove_from_table): Move assertion checking of
1981 hashfn result here. Check hash-equality before calling cmpfn.

1994 value of w32-scroll-lock-modifier is neither nil nor one of the
1995 known key modifiers. (Bug#12806)
1997 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
1999 Shrink struct vectorlike_header to the only size field.
2000 * lisp.h (enum pvec_type): Avoid explicit enum member values.
2002 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and

2030 (allocate_buffer): Use BUFFER_PVEC_INIT.
2031 (live_vector_p): Adjust to match large vector.
2032 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
2033 * buffer.h (struct buffer): Add next member.

2044 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2046 * keyboard.c (event_to_kboard): Do not dereference
2047 frame_or_window field of SELECTION_REQUEST_EVENT
2048 and SELECTION_CLEAR_EVENT events (Bug#12814).
2049 * xterm.h (struct selection_input_event): Adjust comment.
2051 2012-11-07 Eli Zaretskii <eliz@gnu.org>
2053 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
2054 such as Scroll Lock, if the respective keys are treated as
2055 function keys, not as modifiers. This avoids destroying non-ASCII
2056 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
2058 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
2060 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
2062 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2064 Restore some duplicate definitions (Bug#12814).
2065 This undoes part of the 2012-11-03 changes. Some people build
2066 with plain -g rather than with -g3, and they need the duplicate
2067 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
2068 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
2069 Define as macros, as well as as enums or as constants.
2071 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
2073 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
2074 to keypad keys (Bug#12816).
2076 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2078 Minor adjustments of recently-changed frame functions.
2079 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
2080 known to be a frame (we're in the FRAMEP branch).
2081 * lisp.h (Qframep): Remove decl. frame.h declares this.
2082 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
2083 since they're meant for Lisp fixnum values.
2085 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2087 * window.c (Fwindow_combination_limit): Revert to the only
2088 required argument and adjust docstring as suggested in
2089 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
2090 by Martin Rudalics <rudalics@gmx.at>.
2092 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2094 Widely used frame validity and checking functions.
2095 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.

2107 * lisp.h (frame_buffer_predicate): Remove prototype.
2108 * buffer.c (Fother_buffer): Use decode_any_frame.
2109 * xdisp.c (Ftool_bar_lines_needed): Likewise.
2110 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
2111 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
2112 (Fclose_font, Ffont_info): Use decode_live_frame.
2113 * fontset.c (check_fontset_name): Likewise.
2114 * terminal.c (Fframe_terminal): Likewise.
2115 * w32fns.c (check_x_frame): Likewise.
2116 * window.c (Fminibuffer_window, Fwindow_at)
2117 (Fcurrent_window_configuration): Likewise.
2118 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
2119 Likewise. Allow zero number of arguments. Adjust docstring.

2121 * xfaces.c (frame_or_selected_frame): Remove.
2122 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
2123 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
2124 (Fframe_face_alist): Use decode_live_frame.
2125 * xfns.c (check_x_frame): Likewise.
2127 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2129 * window.c (quad): New function.
2130 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
2131 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
2132 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
2133 (Fwindow_line_height): Use it.
2134 (Fwindow_fringes): Use list3.
2135 (Fwindow_scroll_bars): Use list4.
2136 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
2137 (Fwindow_combination_limit): Allow zero number of arguments.
2139 2012-11-05 Eli Zaretskii <eliz@gnu.org>
2141 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
2143 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
2144 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
2145 file descriptor 2 for standard error. (Bug#12805)
2147 2012-11-05 Chong Yidong <cyd@gnu.org>
2149 * process.c (wait_reading_process_output): Revert previous change.
2151 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
2153 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
2154 This removes code that has been obsolete since around 1990.
2155 * callproc.c (Fcall_process):
2157 * process.c (create_process):
2158 * term.c (dissociate_if_controlling_tty):
2159 Assume setsid exists.
2160 * callproc.c (child_setup): Assume setpgid exists and behaves as
2161 per POSIX.1-1988 or later.
2162 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
2163 * emacs.c (shut_down_emacs):
2164 * sysdep.c (sys_suspend, init_foreground_group):
2165 Assume getpgrp behaves as per POSIX.1-1998 or later.
2166 * msdos.c (setpgrp): Remove.
2167 (tcgetpgrp, setpgid, setsid): New functions.
2168 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
2169 * term.c (no_controlling_tty): Remove; unused.
2170 * w32proc.c (setpgrp): Remove.
2171 (setsid, tcgetpgrp): New functions.
2173 Simplify by assuming __fpending.
2174 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
2175 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
2176 Do not assume that __fpending's result fits in int.
2178 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
2180 Remove EMACS_OUTQSIZE+sleep hack.
2181 * dispnew.c (update_frame_1): Remove hack for terminals slower
2182 than 2400 bps, which throttled Emacs by having it sleep.
2183 This code hasn't worked since at least 2007, when the multi-tty stuff
2184 was added, and anyway those old terminals are long dead.
2185 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
2186 without the dispnew.c change, as dispnew.c doesn't include systty.h.
2188 Fix data-loss with --version (Bug#9574).
2189 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
2190 as we can't assume that emacs_strerror is initialized, and strerror
2191 is good enough here.
2192 (main): Invoke atexit earlier, to catch earlier instances of
2193 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
2195 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
2197 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
2198 (keyDown): Remap keypad keys to X11 virtual key codes.
2200 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
2202 Fix data-loss with --batch (Bug#9574).
2203 * emacs.c: Include <close-stream.h>.
2204 (close_output_streams): New function.
2205 (main): Pass it to atexit, so that Emacs closes stdout and stderr
2206 and handles errors appropriately.
2207 (Fkill_emacs): Don't worry about flushing, as close_output_stream
2210 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
2211 The symptom is a diagnostic "GLib-WARNING **: In call to
2212 g_spawn_sync(), exit status of a child process was requested but
2213 SIGCHLD action was set to SIG_IGN and ECHILD was received by
2214 waitpid(), so exit status can't be returned." The diagnostic
2215 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
2216 The real bug is a race condition between Emacs and glib: Emacs
2217 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
2218 so that glib can't find it. Work around the bug by invoking
2219 waitpid only on subprocesses that Emacs itself creates.
2220 * process.c (create_process, record_child_status_change):
2221 Don't use special value -1 in pid field, as the caller now must
2222 know the pid rather than having the callee infer it.
2223 The inference was sometimes incorrect anyway, due to another race.
2224 (create_process): Set new 'alive' member if child is created.
2225 (process_status_retrieved): New function.
2226 (record_child_status_change): Use it.
2227 Accept negative 1st argument, which means to wait for the
2228 processes that Emacs already knows about. Move special-case code
2229 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
2230 processes that have already been waited for, by testing and
2231 clearing new 'alive' member.
2232 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
2233 now does this internally.
2234 (handle_child_signal): Let record_child_status_change do all
2235 the work, since we do not want to reap all exited child processes,
2236 only the child processes that Emacs itself created.
2237 * process.h (Lisp_Process): New boolean member 'alive'.
2239 Omit duplicate definitions no longer needed with gcc -g3.
2240 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
2241 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
2242 Define only as macros. There's no longer any need to also define
2243 these symbols as enums or as constants, since we now assume
2244 gcc -g3 when debugging.
2246 2012-11-03 Eli Zaretskii <eliz@gnu.org>
2248 * lisp.mk: Adjust comments to the fact that term/internal is now
2249 loaded from loadup.el.
2251 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
2252 (msdos_fatal_signal): New function.
2253 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
2256 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
2257 for GCC versions before 4.
2258 (emacs_raise): Define to call msdos_fatal_signal.
2260 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
2261 iterator when starting in the middle of a display or overlay
2264 2012-11-03 Chong Yidong <cyd@gnu.org>
2266 * process.c (wait_reading_process_output): Clean up the last
2269 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
2271 * process.c (wait_reading_process_output): Avoid a race condition
2272 with SIGIO delivery (Bug#11536).
2274 2012-11-03 Chong Yidong <cyd@gnu.org>
2276 * buffer.c (cursor_type): Untabify docstring.
2278 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2280 * frame.h (struct frame): Drop can_have_scroll_bars member
2281 which is meaningless for a long time. Adjust comments.
2282 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
2283 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
2285 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2287 * window.c (decode_next_window_args): Update window arg after
2288 calling decode_live_window and so fix crash reported at
2289 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
2290 by Juanma Barranquero <lekktu@gmail.com>.
2291 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
2292 * font.c (Ffont_at): Likewise.
2294 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
2296 * widget.c (resize_cb): New function.
2297 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
2298 (EmacsFrameResize): Check if all is up to date before changing frame
2301 2012-11-02 Eli Zaretskii <eliz@gnu.org>
2303 Implement backtrace output for fatal errors on MS-Windows.
2304 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
2305 (BACKTRACE_LIMIT_MAX): New macro.
2306 (w32_backtrace): New function.
2307 (emacs_abort): Use w32_backtrace when the user chooses not to
2308 attach a debugger. Update the text of the abort dialog.
2310 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2312 Window-related stuff cleanup here and there.
2313 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
2314 Use decode_any_window.
2315 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
2316 * xdisp.c (Fformat_mode_line): Likewise.
2317 * font.c (Ffont_at): Use decode_live_window.

2322 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
2323 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
2326 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2328 Remove pad from struct input_event.
2329 * termhooks.h (struct input_event): Remove padding field.
2331 * keyboard.c (event_to_kboard): Simplify because frame_or_window
2332 member is never cons for a long time. Adjust comment.
2333 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
2334 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
2335 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
2336 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
2338 2012-11-01 Eli Zaretskii <eliz@gnu.org>
2340 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
2342 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
2344 Fix crash when using Emacs as commit editor for git (Bug#12697).
2345 * callproc.c (setpgrp): Remove macro, as we now use setpgid
2346 and it is configured in conf_post.h.
2347 (Fcall_process): Don't invoke both setsid and setpgid; the former
2348 is enough, if it exists.
2349 * callproc.c (Fcall_process, child_setup):
2350 * process.c (create_process): Use setpgid.
2351 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
2353 * dispnew.c (init_display): Initialize the foreground group
2354 if we are running a tty display.
2355 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
2356 * lisp.h (init_foreground_group): New decl.
2357 * sysdep.c (inherited_pgroup): New static var.
2358 (init_foreground_group, tcsetpgrp_without_stopping)
2359 (narrow_foreground_group, widen_foreground_group): New functions.
2360 (init_sys_modes): Narrow foreground group.
2361 (reset_sys_modes): Widen foreground group.
2363 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
2365 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
2367 2012-10-31 Martin Rudalics <rudalics@gmx.at>
2369 * minibuf.c (read_minibuf): Restore current buffer since
2370 choose_minibuf_frame calling Fset_frame_selected_window may
2371 change it (Bug#12766).
2373 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
2375 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
2377 2012-10-30 Kenichi Handa <handa@gnu.org>
2379 * font.c (Ffont_at): If WINDOW is specified and it is not
2380 displaying the current buffer, signal an error.
2382 2012-10-29 Daniel Colascione <dancol@dancol.org>
2384 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
2385 In preparation for fixing bug#12739, move these functions from
2388 * coding.h, coding.c: ... to here, and compile them only when
2389 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
2390 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
2392 2012-10-28 Eli Zaretskii <eliz@gnu.org>
2394 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
2395 (timer_loop, getitimer, setitimer): Use it instead of
2396 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
2398 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
2401 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
2403 * nsterm.m (NO_APPDEFINED_DATA): New define.

2405 (last_appdefined_event): Remove.
2406 (ns_select): Initialize t from last_appdefined_event_data instead
2407 of [last_appdefined_event data1].
2408 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
2409 remove last_appdefined_event (Bug#12698).
2411 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
2413 * frame.c (x_set_font): Catch internal error.
2415 2012-10-27 Eli Zaretskii <eliz@gnu.org>
2417 Avoid overflow in w32 implementation of interval timers.
2418 When possible, for ITIMER_PROF count only times the main thread
2420 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
2421 'volatile ULONGLONG' types. All the other data which was
2422 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
2423 (GetThreadTimes_Proc): New typedef.
2424 (w32_get_timer_time): New function, returns a suitable time value
2426 (timer_loop): Enter critical section when accessing ULONGLONG
2427 values of the itimer_data struct, as these accesses are no longer
2428 atomic. Call 'w32_get_timer_time' instead of 'clock'.
2429 Remove unused variable.
2430 (init_timers): Initialize s_pfn_Get_Thread_Times.
2431 (start_timer_thread): Don't assign itimer->caller_thread here.
2432 (getitimer): Assign itimer->caller_thread here.
2433 (setitimer): Always call getitimer to get the value of ticks_now.
2434 (sys_spawnve): Avoid compiler warning about format mismatch.
2436 2012-10-26 Eli Zaretskii <eliz@gnu.org>
2438 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
2439 mouse movement events if the menu bar is active. This avoids
2440 producing a busy "hour-glass" cursor by Windows if the mouse
2441 pointer is positioned over a tooltip shown for some menu item.
2443 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
2445 Don't assume process IDs fit in int.
2446 * emacs.c (shut_down_emacs) [!DOS_NT]:
2447 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
2448 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
2449 Use pid_t, not int, to store process IDs, as 'int'
2450 is not wide enough on a few platforms (e.g., AIX and IRIX).
2452 2012-10-23 Kenichi Handa <handa@gnu.org>
2454 The following change is to make face-font-rescale-alist work
2455 correctly for non-ASCII fonts.
2457 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
2458 (font_open_for_lface): Handle Vface_font_rescale_alist.
2460 2012-10-23 Chong Yidong <cyd@gnu.org>
2462 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
2464 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>

2468 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
2470 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
2473 2012-10-21 Glenn Morris <rgm@gnu.org>
2475 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
2477 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
2479 Port to OpenBSD 5.1.
2480 * frame.c (Fmouse_position, Fmouse_pixel_position):
2481 * xdisp.c (produce_stretch_glyph):
2482 Declare local vars only when they're needed.
2483 This is clearer and avoids a warning on OpenBSD about unused vars.
2484 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
2485 This is safer, and avoids OpenBSD warnings about unused vars.
2486 * keyboard.c (record_menu_key): Remove unnecessary decl.
2487 (poll_timer): Define only if POLL_FOR_INPUT is defined.
2488 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
2489 as our definition clashes with OpenBSD's.
2490 * xfaces.c (load_face_colors, check_lface_attrs)
2491 (get_lface_attributes_no_remap, get_lface_attributes)
2492 (lface_fully_specified_p, x_supports_face_attributes_p)
2493 (tty_supports_face_attributes_p, face_fontset, realize_face)
2494 (realize_x_face, realize_tty_face):
2495 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
2496 merely Lisp_Object *. This is more informative and avoids
2497 a warning on OpenBSD about accessing beyond an object's size.
2499 2012-10-20 Chong Yidong <cyd@gnu.org>
2501 * lread.c (Fload): Doc fix (Bug#12592).
2503 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
2505 * font.c (Ffont_at): Fix previous change.
2507 2012-10-19 Eli Zaretskii <eliz@gnu.org>
2509 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
2510 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html

2527 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
2528 (staticpro): If we run out of staticpro slots, die with an
2529 informative error instead of just calling emacs_abort.
2531 2012-10-18 Martin Rudalics <rudalics@gmx.at>
2533 Fix two flaws reported by Dmitry Antipov.

2790 (get_input_pending): Remove first argument, since it was always
2791 the same pointer-to-int (now pointer-to-boolean) &input_pending,
2792 and behave as if it had that value. Return new value of
2793 input_pending. All callers changed.
2794 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
2795 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's

2824 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
2826 * commands.h (immediate_quit): Remove duplicate decl.

2837 * w32fns.c (w32_last_error): Change the return value to DWORD, to
2838 match what GetLastError returns. Explain why the function is
2841 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
2842 'is_tooltip_frame', to avoid confusion with its global namesake.
2844 2012-10-08 Daniel Colascione <dancol@dancol.org>
2846 * xdisp.c (start_hourglass): Call w32_note_current_window when
2847 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
2848 build that caused Emacs to display the hourglass cursor forever.
2850 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
2851 which is broken under remote desktop, calculate the number of
2852 colors available for a display based on the display's number of
2853 planes and number of bits per pixel per plane. (bug#10397).
2855 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
2857 * nsfont.m (Vfonts_in_cache): New variable.
2858 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
2859 are used. Add cached fonts to Vfonts_in_cache.
2860 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
2862 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
2864 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
2866 (FONT_H): Define after FRAME_H.
2867 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
2868 Update dependencies.
2870 * w32term.c: Remove leftover declaration of keyboard_codepage.
2872 2012-10-08 Eli Zaretskii <eliz@gnu.org>
2874 * makefile.w32-in (FONT_H): Add $(FRAME_H).
2875 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
2876 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
2877 (GLOBAL_SOURCES): Add cygw32.c.
2878 ($(BLD)/unexw32.$(O)):
2880 ($(BLD)/w32console.$(O)):
2881 ($(BLD)/w32fns.$(O)):
2882 ($(BLD)/w32heap.$(O)):
2883 ($(BLD)/w32menu.$(O)):
2884 ($(BLD)/w32proc.$(O)): Add w32common.h.
2886 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
2888 (x_to_w32_color): Don't modify the argument, modify a copy instead.
2890 2012-10-08 Daniel Colascione <dancol@dancol.org>
2892 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
2893 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
2894 accidental message numbering hole. Change other messages to
2897 * w32select.h (HAVE_W32SELECT): Remove.
2899 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
2900 w32common.h instead of w32heap.h.
2902 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
2903 (get_allocation_unit, get_processor_type, get_w32_major_version)
2904 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
2905 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
2906 (OS_NT, os_subtype, cache_system_info): Move declarations to
2909 * w32heap.c: Include w32common.h.
2910 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
2911 (w32_minor_version, w32_build_number, w32_subtype):
2912 Remove duplicate definitions.
2914 * w32fns.c: Include w32common.h; include w32heap.h only in
2917 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
2918 Use `report_file_error' instead of `error' in order to better
2919 inform users of what went wrong. Increase NTGUI_UNICODE file
2920 dialog box file name length to 32k, the maximum allowed by the NT
2923 * w32common.h: New file.
2924 (ROUND_UP, ROUND_DOWN, get_page_size)
2925 (get_allocation_unit, get_processor_type, get_w32_major_version)
2926 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
2927 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
2928 (OS_NT, os_subtype, cache_system_info): Move here.
2930 * unexw32.c, unexcw.c: Include w32common.h.
2932 * emacs.c (main): Use (defined (WINDOWSNT) || defined
2933 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
2934 to call syms_of_w32select.
2936 * cygw32.h: Remove obsolete EXFUN declarations.
2938 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
2940 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
2941 of w32inevt.o from SOME_MACHINE_OBJECTS.
2943 2012-10-08 Daniel Colascione <dancol@dancol.org>
2945 * image.c: Permanent fix for JPEG compilation issue --- limit
2946 jpeglib `boolean' redefinition to Cygwin builds.
2948 2012-10-08 Eli Zaretskii <eliz@gnu.org>
2950 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
2952 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
2955 2012-10-08 Daniel Colascione <dancol@dancol.org>
2957 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
2958 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
2959 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
2960 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
2961 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
2962 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
2963 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
2964 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
2965 now a supported configuration.
2967 * Makefile.in: consolidate image variables into LIBIMAGE; add
2968 W32_OBJ and W32_LIBS. Compile new files.
2971 (_DebPrint) declare tracing facility for W32 debugging. We need
2972 to unify tracing later.
2974 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
2975 unconditional use of W32 Unicode functions. Cygwin runs only on
2976 100% Unicode operating systems.
2978 * cygw32.c: New file. Define Cygwin-specific facilities.
2979 (Fcygwin_convert_path_to_windows)
2980 (Fcygwin_convert_path_from_windows): New user functions for
2981 accessing Cygwin path-munging routines.
2983 * cygw32.h: New file.
2984 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
2985 UTF-16LE strings temporarily inside non-Lisp-visible string
2988 (w32_strerror): Just what it says on the tin.
2990 * emacs.c: Make the NS fork-then-exec code for daemon-launching
2991 also run for Cygwin; both systems have the same problem with using
2992 GUI facilities in a forked child. Also call syms_of_cygw32,
2993 syms_of_w32select in correct places.
2995 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
2996 needs fork-then-exec for daemon launching.
2998 * font.h: Include frame.h.
3000 * image.c: Use the image library cache machinery only when we're
3001 compiling for native WINDOWSNT; Cygwin can use shared libraries
3002 like any other Unixlike system.
3004 * keyboard.c: Clarify a comment regarding the input loop.
3006 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
3007 functions directly instead of trying to detect at runtime that our
3008 host operating system supports them. We make this change for two
3009 reasons: Cygwin lacks support for the multibyte character
3010 conversion functions used by the legacy menu code, and Cygwin
3011 never needs to rely on non-Unicode APIs.
3013 * unexw32.c (hinst): Declare extern.
3015 * w32.c: Change header order;
3016 (w32_strerror): Move to w32fns.c because we need it for
3017 non-WINDOWSNT builds.
3019 * w32.h: Add #error macro to make sure we don't include w32.h for
3020 Cygwin builds. Remove w32select declarations.
3022 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
3023 w32fns.c. w32console.c is WINDOWSNT-only.
3025 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
3026 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
3028 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
3029 (w32_major_version, w32_minor_version, w32_build_number)
3030 (os_subtype, sound_type): Define here
3031 (w32_defined_color): Make color parameter const for consistency
3032 with other _defined_color functions.
3033 (w32_createwindow): Unconditionally call w32_init_class instead of
3034 doing so only when hprevinst is non-NULL. Plumbing hprevinst
3035 through the code is complex and unnecessary because class
3036 registration is practically free.
3037 (w32_name_of_message): New EMACSDEBUG-only function.
3038 (Fset_message_beep): Move here
3039 (Fx_open_connection): Require that the display name for Windows be
3040 "w32" for consistency, emacsclient disambiguation, and maybe, one
3041 day, multi-window-system support.
3042 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
3043 Cygwin files for W32 GUI facilities, since these clearly don't
3044 expect Cygwin names.
3045 (_DebPrint): Define.
3046 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
3047 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
3048 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
3049 (w32_last_error): Remove.
3051 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
3053 * w32heap.c (syspage_mask): Declare here.
3054 (cache_system_info): Remove.
3056 * w32inevt.c (faked_key): Define globally, not statically.
3057 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
3058 (w32_console_toggle_lock_key): Move to w32fns.c.
3060 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
3062 * w32proc.c (_DebPrint): Move to w32fns.c.
3063 * w32select.c: Include string.h, stdio.h for Cygwin.
3064 * w32select.h: New File.
3066 * w32term.c: Include io.h for non-CYGWIN builds; needed for
3068 (w32_message_fd): New variable. Under Cygwin, holds the file
3069 descriptor the system used to tell us about pending thread
3072 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
3073 that prevented compilation under non-WINDOWSNT systems.
3075 (w32_initialize): Open /dev/windows and assign it to
3076 w32_message_fd. Provide w32 feature.
3078 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
3079 (WM_EMACS_INPUT_READY): add.
3080 (prepend_msg, w32_message_fd): Declare globally.
3083 (keyboard_handle): Use only when WINDOWSNT.
3084 (notify_msg_ready): New function. Posts a message to the main
3085 thread's message queue under CYGWIN, which wakes up the main
3086 thread from select(2) by making the /dev/windows file descriptor
3087 ready. Under WINDOWSNT, it sets an event the same way the old
3090 (post, prepend_msg): Actually call notify_msg_ready instead of
3091 setting the input event directly.
3093 2012-10-07 Eli Zaretskii <eliz@gnu.org>
3095 * ralloc.c (relinquish): If a heap is ready to be relinquished,
3096 but it still has blocs in it, don't return it to the system,
3097 instead of aborting. (Bug#12402)
3099 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
3101 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
3103 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
3104 MAC_OS_X_VERSION_10_6.
3105 (syms_of_nsterm): Remove comment about Panther and above for
3107 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.

3109 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
3111 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
3112 MAC_OS_X_VERSION_10_4.
3114 * nsmenu.m (fillWithWidgetValue:): Remove code for <
3115 MAC_OS_X_VERSION_10_2.
3117 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
3119 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
3120 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
3122 * nsterm.m (ns_in_resize): Remove (Bug#12479).
3123 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
3124 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
3125 Remove ns_in_resize check.
3126 (ns_clear_frame_area): Remove resize handle code.
3128 * nsfns.m (ns_in_resize): Remove.
3129 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
3130 Remove ns_in_resize check.
3132 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
3134 Improve sys_siglist detection.
3135 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
3136 defined as a macro, as is done in Solaris.
3137 (sys_siglist_entries): New macro.
3138 (save_strsignal): Use it.
3139 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
3140 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
3142 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
3144 * nsfns.m (Fx_create_frame): Call x_default_parameter with
3145 fullscreen/Fullscreen.
3147 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
3148 tobar_height is new.
3150 * nsterm.m (x_make_frame_visible): Check for fullscreen.
3151 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
3152 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
3153 (windowDidResize:): Check for correct window if old style fullscreen.
3154 Capitalize word in comment. Remove incorrect comment.
3155 (initFrameFromEmacs:): tbar_height renamed tibar_height.
3156 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
3157 error in drawing background.
3158 (toggleFullScreen:): Remove comment. Rearrange calls.
3159 Set toolbar values to zero, save old height in tobar_height.
3160 Restore tool bar height when leaving fullscreen.
3161 (canBecomeMainWindow): New function.
3163 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
3165 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
3167 2012-10-05 Eli Zaretskii <eliz@gnu.org>
3169 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
3171 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
3172 that time stamps of directories could also be changed.
3173 Don't request the too broad GENERIC_WRITE, only the more restrictive
3174 FILE_WRITE_ATTRIBUTES access rights.
3176 * fileio.c (Fset_file_times): Special-case ignoring errors for
3177 directories only on MSDOS, not on MS-Windows.
3179 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
3181 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
3183 2012-10-04 Eli Zaretskii <eliz@gnu.org>
3185 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
3186 see whether CreateFile failed.
3188 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
3190 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
3191 to avoid similar races.
3192 * keyboard.c (pending_signals): Now bool, not int.
3194 Port timers to OpenBSD, plus check for timer failures.
3195 OpenBSD problem reported by Han Boetes.
3196 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
3198 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
3199 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
3200 like OpenBSD, which has timer_settime but does not declare it.
3201 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
3202 whether to use itimerspec-related primitives. All uses of
3203 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
3205 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3207 * profiler.c (handle_profiler_signal): Fix a malloc race
3208 that caused Emacs to hang on Fedora 17 when profiling Lisp.

3212 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
3214 2012-10-02 Eli Zaretskii <eliz@gnu.org>
3216 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
3217 consistent with the change in return value of 'safe_strsignal'.
3219 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3221 Prefer plain 'static' to 'static inline' (Bug#12541).
3222 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
3223 (bidi_set_sor_type, bidi_push_embedding_level)
3224 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
3225 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
3226 (bidi_cache_search, bidi_cache_ensure_space)
3227 (bidi_cache_iterator_state, bidi_cache_find)
3228 (bidi_peek_at_next_level, bidi_set_paragraph_end)
3229 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
3230 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
3231 Now 'static', not 'static inline'.
3233 Count overruns when profiling; change units to ns.
3234 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
3235 Give extra weight to samples after overruns, to attempt to count
3236 the time more accurately.
3237 (setup_cpu_timer): Change sampling interval units from ms to ns, since
3238 the underlying primitives nominally do ns.
3239 (Fprofiler_cpu_start): Document the change. Mention that
3240 the sampling intervals are only approximate.
3242 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
3244 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
3246 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
3247 case for the special 0 coding-system.
3249 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
3250 (Fmake_overlay): Remove redundant tests.
3251 (fix_start_end_in_overlays): Remove redundant recentering.
3253 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
3255 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
3256 Update dependencies.
3258 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3260 Fix a malloc race condition involving strsignal.
3261 A signal can arrive in the middle of a malloc, and Emacs's signal
3262 handler can invoke strsignal, which can invoke malloc, which is
3263 not portable. This race condition bug makes Emacs hang on GNU/Linux.
3264 Fix it by altering the signal handler so that it does not invoke
3266 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
3267 * process.c (status_message): Use const pointer, in case strsignal
3268 is #defined to safe_strsignal.
3269 * sysdep.c (sys_siglist, init_signals): Always define and
3270 initialize a substitute sys_siglist if the system does not define
3271 one, even if HAVE_STRSIGNAL.
3272 (safe_strsignal): Rename from strsignal. Always define,
3273 using sys_siglist. Return a const pointer.
3274 * syssignal.h (safe_strsignal): New decl.
3275 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
3277 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3279 * w32proc.c (timer_loop): Fix code that waits for timer
3280 expiration, to avoid high CPU usage.
3282 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
3284 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
3285 (sweep_weak_table): Remove redundant prototypes.
3287 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
3289 * emacs.c: Move the inclusion of TERM_HEADER after including
3290 windows.h on WINDOWSNT. This avoids compilation problems with
3293 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3295 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
3296 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
3297 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
3298 as the previous version used 'void *'.
3300 * ralloc.c (ROUNDUP): Fix last change.
3301 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
3304 * w32proc.c <disable_itimers>: New static flag.
3305 (init_timers): Initialize it to zero, after creating the critical
3306 sections used by the timer threads.
3307 (term_timers): Set to 1 before deleting the critical sections.
3308 (getitimer, setitimer): If disable_itimers is non-zero, return an
3309 error indication without doing anything. Reported by Fabrice
3310 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
3311 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
3313 [!HAVE_SETITIMER]: Behave as the previous version that didn't
3316 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
3317 term_ntproc after all the other bookkeeping, to get timers working
3318 as long as possible.
3320 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3322 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
3323 Suggested by Juri Linkov in
3324 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
3326 Prefer plain 'static' to 'static inline' (Bug#12541).
3327 With static functions, modern compilers inline pretty well by
3328 themselves; advice from programmers often hurts as much as it helps.
3329 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
3330 this change shrinks the text size of the Emacs executable by 1.1%
3331 without affecting CPU significantly in my benchmark.
3332 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

3411 (bidi_copy_it): Do the whole copy with a single memcpy.
3412 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
3414 Revert the FOLLOW-SYMLINKS change for file-attributes.
3415 Doing it right would require several changes to Tramp, and there's
3416 not enough time to get that tested before the freeze today.
3417 * dired.c (directory_files_internal, Ffile_attributes):
3420 * frame.c (x_report_frame_params): Port better to wider ints.
3421 Do not assume that EMACS_UINT is the same width as uprintmax_t,
3422 or that pointers can be printed in 15 decimal digits.
3423 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

3454 * w32.c (init_environment, get_emacs_configuration): Support AMD64
3456 (init_ntproc): Cast arguments of _open_osfhandle to intptr_t, for
3457 compatibility with x64.
3459 * vm-limit.c (lim_data): Now size_t.
3460 (check_memory_limits): Adjust prototypes of real_morecore and
3461 __morecore to receive argument of type ptrdiff_t. Use size_t for
3462 five_percent and data_size.
3464 * unexw32.c: Use DWORD_PTR instead of DWORD for file-scope
3465 variables, for compatibility with x64.

3487 * frame.c (x_report_frame_params): Use EMACS_UINT for the return
3488 value of FRAME_X_WINDOW, to fit a 64-bit pointer on 64-bit Windows

3517 (struct itimer_data): New definition.
3518 (ticks_now, real_itimer, prof_itimer, clocks_min, crit_real)

3525 * w32.c (term_ntproc): Call term_timers.
3526 (init_ntproc): Make sure all signals are unblocked at startup, to
3527 erase any traces of dumping. Call init_timers.

3530 Windows-specific code to display the hourglass mouse pointer is no
3532 (w32_wnd_proc): Remove code that handled the WM_TIMER message due
3533 to hourglass timer expiration.

3607 2012-09-30 Eli Zaretskii <eliz@gnu.org>
3609 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
3610 HAVE_TIMER_SETTIME is defined.

3614 Profiler improvements: more-accurate timers, overflow checks.
3615 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
3616 signal.h, setjmp.h. Include systime.h instead.
3617 (saturated_add): New function.
3618 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.
3619 (record_backtrace, handle_profiler_signal): Saturate on fixnum overflow.

3623 (profiler_cpu_running): Now of that enum type, not bool.
3624 All uses changed to store the new value.
3625 (handle_profiler_signal): Rename from sigprof_handler_1,
3626 for consistency with other handlers. Do not check whether
3627 cpu_log is a hash-table if garbage collecting, since it
3628 doesn't matter in that case.
3629 (deliver_profiler_signal): Rename from sigprof_handler,
3630 for consistency with other handlers.
3631 (setup_cpu_timer): New function, with much of what used to be in
3632 Fprofiler_cpu_start. Check for out-of-range argument.
3633 Prefer timer_settime if available, and prefer
3634 thread cputime clocks, then process cputime clocks, then
3635 monotonic clocks, to the old realtime clock. Use make_timeval
3636 to round more-correctly when falling back to setitimer.
3637 (Fprofiler_cpu_start): Use it.
3638 (Fprofiler_cpu_stop): Prefer timer_settime if available.
3639 Don't assume that passing NULL as the 2nd argument of setitimer
3640 is the same as passing a pointer to all-zero storage.
3641 Ignore SIGPROF afterwards.
3642 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
3643 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
3644 non-fatal signal handlers. Ignore SIGPROF on startup.
3645 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
3646 in profiler.c, since sysdep.c now uses it.
3648 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
3649 Suggested by Eli Zaretskii in

3668 (Frun_hook_with_args_until_failure): Doc fixes.
3670 2012-09-28 Eli Zaretskii <eliz@gnu.org>
3672 * xdisp.c (syms_of_xdisp) <Qredisplay_internal>: Rename from
3673 Qautomatic_redisplay and change the symbol name. All users changed.
3675 2012-09-28 Tomohiro Matsuyama <tomo@cx4a.org>
3677 * profiler.c (sigprof_handler): Fix race condition.

3683 2012-09-27 Paul Eggert <eggert@cs.ucla.edu>
3685 Check more robustly for timer_settime.
3686 * Makefile.in (LIB_TIMER_TIME): New macro.
3688 * atimer.c (alarm_timer, alarm_timer_ok, set_alarm, init_atimer):
3689 Use HAVE_TIMER_SETTIME, not SIGEV_SIGNAL, to decide whether to

3702 * character.h (MAYBE_UNIFY_CHAR): Remove.
3703 * charset.c, charset.h (maybe_unify_char): Now static.
3704 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
3705 Since this stuff is now private to charset.c, there's no need for
3706 a public macro and no need to inline by hand.

3737 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
3739 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
3741 Prefer POSIX timers if available.
3742 They avoid a race if the timer is too close to the current time.
3743 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
3744 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
3745 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
3747 2012-09-25 Eli Zaretskii <eliz@gnu.org>
3749 * coding.c (CHAR_STRING_ADVANCE_NO_UNIFY): Make it an alias of
3750 CHAR_STRING_ADVANCE.

3752 STRING_CHAR_ADVANCE.
3754 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
3756 Move Vlibrary_cache to emacs.c and reset before dumping.
3758 * lisp.h (reset_image_types): Declare.
3759 [WINDOWSNT] (Vlibrary_cache): Declare.
3761 * image.c (reset_image_types): New function.
3763 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.

3774 * w32proc.c (sys_signal): Handle all signals defined by the
3775 MS-Windows runtime, not just SIGCHLD. Actually install the signal
3776 handlers for signals supported by Windows. Don't override
3777 term_ntproc as the handler for SIGABRT.
3778 (sigaction): Rewrite to call sys_signal instead of duplicating its
3780 (sys_kill): Improve commentary.
3782 * w32.c (term_ntproc): Accept (and ignore) one argument, for
3783 consistency with a signature of a signal handler. All callers
3785 (init_ntproc): Accept an argument DUMPING. If dumping, don't
3786 install term_ntproc as a signal handler for SIGABRT, as that
3787 should be done by the dumped Emacs.
3789 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
3791 * w32select.c (term_w32select): Protect against repeated
3792 invocation by setting clipboard_owner to NULL after calling

3796 and term_ntproc to their modified signatures.
3798 * character.c (char_string, string_char): Remove calls to
3799 MAYBE_UNIFY_CHAR. See the discussion starting at
3800 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
3803 2012-09-25 Chong Yidong <cyd@gnu.org>

3807 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
3809 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
3810 when encountering an unknown bytecode.
3812 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
3814 image.c, indent.c: Use bool for booleans.
3815 * dispextern.h (struct image_type): Members valid_p, load, init
3816 now return bool, not int. All uses changed.
3817 * image.c: Omit unnecessary static decls.
3818 (x_create_bitmap_mask, x_build_heuristic_mask):
3819 Return void, not int, since callers don't care about the return value.

3848 Use bool for booleans.
3850 2012-09-24 Chong Yidong <cyd@gnu.org>
3852 * chartab.c (Fset_char_table_default): Obsolete function removed.
3854 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3856 Move pid_t related decls out of lisp.h.
3857 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
3858 (interruptible_wait_for_termination):
3859 Move these decls from lisp.h to syswait.h, since they use pid_t.
3860 Needed on FreeBSD; see Herbert J. Skuhra in
3861 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
3862 * callproc.c: Include syswait.h.

3879 * nsmenu.m (ns_update_menubar):
3880 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
3881 * xfns.c (Fx_show_tip) [USE_GTK]:
3882 Use bool for boolean.
3883 * gtkutil.c (xg_update_frame_menubar):
3884 * xmenu.c (update_frame_menubar):
3885 Return void, not int, since caller ignores return value.
3886 * gtkutil.c (xg_change_toolbar_position):
3889 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
3891 * makefile.w32-in (BLOCKINPUT_H): Remove.

3908 2012-09-23 Eli Zaretskii <eliz@gnu.org>
3910 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
3911 fatal_error_backtrace.
3913 * w32proc.c (sys_kill): Undo last change: don't do anything when
3914 invoked to deliver SIGABRT to our own process. This is now
3915 handled by emacs_raise.
3917 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
3919 * w32term.c (w32_read_socket): Remove leftover reference to
3920 interrupt_input_pending.
3922 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3924 Do not use SA_NODEFER.
3925 Problem reported by Dani Moncayo in
3926 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
3928 * sysdep.c (emacs_abort): Do not reset signal handler.
3929 * emacs.c (terminate_due_to_signal): Reset signal handler here.
3930 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
3931 wanted even on POSIXish hosts, and it doesn't work on Windows.
3933 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3935 * xterm.c (x_term_init): Call fixup_locale before and after calling
3936 gtk_init (Bug#12392).
3938 2012-09-23 Chong Yidong <cyd@gnu.org>
3940 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
3941 Vdynamic_library_alist.
3943 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
3944 (Fgnutls_available_p): Caller changed.
3946 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
3947 (Flibxml_parse_xml_region): Likewise.
3949 * dispextern.h (struct image_type): Remove arg from init function.
3951 * image.c (Finit_image_library, lookup_image_type)
3952 (define_image_type): Remove now-unneeded second arg.
3953 (init_xpm_functions, init_png_functions, init_jpeg_functions)
3954 (init_tiff_functions, init_gif_functions, init_svg_functions):
3955 Arglist and w32_delayed_load calling convention changed.
3956 (gs_type): Remove init_gs_functions; there is no such function.
3957 (valid_image_p, make_image): Fix caller to lookup_image_type.
3959 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3961 Simplify and avoid signal-handling races (Bug#12471).
3963 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
3964 Avoid recursive loop if there's a fatal error in the function itself.
3965 * atimer.c (pending_atimers):
3966 * blockinput.h: Don't include "atimer.h"; no longer needed.
3967 (interrupt_input_pending): Remove. All uses removed.
3968 pending_signals now counts both atimers and ordinary interrupts.
3969 This is less racy than having three separate pending-signal flags.
3970 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
3972 Rename from their upper-case counterparts BLOCK_INPUT,
3973 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
3974 INPUT_BLOCKED_P, and turn into functions. All uses changed.
3975 This makes it easier to access volatile variables more accurately.
3976 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
3977 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
3978 that's more reliable if the code is buggy and sets
3979 interrupt_input_blocked to a negative value. All uses changed.
3980 * atimer.c (deliver_alarm_signal):
3981 Remove. No need to deliver this to the parent; any thread can
3982 handle this signal now. All uses replaced by underlying handler.
3983 * atimer.c (turn_on_atimers):
3984 * dispnew.c (handle_window_change_signal):
3985 * emacs.c (handle_danger_signal):
3986 * keyboard.c (kbd_buffer_get_event):
3987 Don't reestablish signal handler; not needed with sigaction.
3988 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
3990 Rework to avoid unnecessary accesses to volatile variables.
3991 (UNBLOCK_INPUT_TO): Now a function.
3992 (totally_unblock_input, unblock_input): New decls.
3993 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
3994 (init_data): Remove. Necessary stuff now done in init_signal.
3995 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
3996 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
3997 (fatal_error_code): Remove; no longer needed.
3998 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
3999 it doesn't always backtrace. All uses changed. No need to reset
4000 signal to default, since sigaction and/or die does that for us now.
4001 Use emacs_raise (FOO), not kill (getpid (), FOO).
4002 (main): Check more-accurately whether we're dumping.
4003 Move fatal-error setup to sysdep.c
4004 * floatfns.c: Do not include "syssignal.h"; no longer needed.
4005 * gtkutil.c (xg_get_file_name, xg_get_font):
4006 Remove no-longer-needed signal-mask manipulation.
4007 * keyboard.c, process.c (POLL_FOR_INPUT):
4008 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
4009 * keyboard.c (read_avail_input): Remove.
4010 All uses replaced by gobble_input.
4011 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
4012 (kbd_buffer_store_event_hold, gobble_input):
4013 (record_asynch_buffer_change) [USABLE_SIGIO]:
4014 (store_user_signal_events):
4015 No need to mess with signal mask.
4016 (gobble_input): If blocking input and there are terminals, simply
4017 set pending_signals to 1 and return. All hooks changed to not
4018 worry about whether input is blocked.
4019 (process_pending_signals): Clear pending_signals before processing
4020 them, in case a signal comes in while we're processing.
4021 By convention callers now test pending_signals before calling us.
4022 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
4023 New functions, to support changes to blockinput.h.
4024 (handle_input_available_signal): Now extern.
4025 (reinvoke_input_signal): Remove. All uses replaced by
4027 (quit_count): Now volatile, since a signal handler uses it.
4028 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
4029 All callers changed. Block SIGINT only if not already blocked.
4030 Clear sigmask reliably, even if Fsignal returns, which it can.
4031 Omit unnecessary accesses to volatile var.
4032 (quit_throw_to_read_char): No need to restore sigmask.
4033 * keyboard.c (gobble_input, handle_user_signal):
4034 * process.c (wait_reading_process_output):
4035 Call signal-handling code rather than killing ourselves.
4036 * lisp.h: Include <float.h>, for...
4037 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
4038 (pending_signals): Now volatile.
4039 (syms_of_data): Now const if IEEE floating point.
4040 (handle_input_available_signal) [USABLE_SIGIO]:
4041 (terminate_due_to_signal, record_child_status_change): New decls.
4042 * process.c (create_process): Avoid disaster if memory is exhausted
4043 while we're processing a vfork, by tightening the critical section
4045 (send_process_frame, process_sent_to, handle_pipe_signal)
4046 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
4048 (send_process): No need for setjmp/longjmp any more, since the
4049 SIGPIPE stuff is now gone. Instead, report an error if errno
4051 (record_child_status_change): Now extern. PID and W are now args.
4052 Return void, not bool. All callers changed.
4053 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
4054 Remove. All uses removed. This bug should be fixed now in a
4056 (wait_for_termination_1): Use waitpid rather than sigsuspend,
4057 and record the child status change directly. This avoids the
4058 need to futz with the signal mask.
4059 (process_fatal_action): Move here from emacs.c.
4060 (emacs_sigaction_flags): New function, containing
4061 much of what used to be in emacs_sigaction_init.
4062 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
4063 caught by emacs, to make races less likely.
4064 (deliver_process_signal): Rename from handle_on_main_thread.
4066 (BACKTRACE_LIMIT_MAX): Now at top level.
4067 (thread_backtrace_buffer, threadback_backtrace_pointers):
4069 (deliver_thread_signal, deliver_fatal_thread_signal):
4070 New functions, for more-accurate delivery of thread-specific signals.
4071 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
4072 (deliver_arith_signal): Handle in this thread, not
4073 in the main thread, since it's triggered by this thread.
4074 (maybe_fatal_sig): New function.
4075 (init_signals): New arg DUMPING so that we can be more accurate
4076 about whether we're dumping. Caller changed.
4077 Treat thread-specific signals differently from process-general signals.
4078 Block all signals while handling fatal error; that's safer.
4079 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
4081 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
4082 Ignore SIGPIPE unless batch.
4083 (emacs_backtrace): Output backtrace for the appropriate thread,
4084 which is not necessarily the main thread.
4085 * syssignal.h: Include <stdbool.h>.
4086 (emacs_raise): New macro.
4087 * xterm.c (x_connection_signal): Remove; no longer needed
4088 now that we use sigaction.
4089 (x_connection_closed): No need to mess with sigmask now.
4090 (x_initialize): No need to reset SIGPIPE handler here, since
4091 init_signals does this for us now.
4093 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4095 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
4096 background rect may be larger (Bug#12245).
4098 2012-09-23 Chong Yidong <cyd@gnu.org>
4100 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
4102 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4104 * .gdbinit: Just stop at fatal_error_backtrace.
4105 See Stefan Monnier's request in
4106 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
4107 Remove no-longer-used query of system type.
4109 2012-09-22 Chong Yidong <cyd@gnu.org>
4111 * search.c (Freplace_match): Doc fix (Bug#12325).
4113 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
4115 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
4116 (Fline_end_position): Doc fix.
4118 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
4120 2012-09-22 Chong Yidong <cyd@gnu.org>
4122 * dispextern.h (struct image_type): Add new slot, storing a type
4123 initialization function.
4125 * image.c (define_image_type): Call the image initializer function
4126 if it is defined. Arguments and return value changed.
4127 (valid_image_p, make_image): Callers changed.
4128 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
4129 (gif_type, imagemagick_type, svg_type, gs_type):
4130 Add initialization functions.
4131 (Finit_image_library): Call lookup_image_type.
4132 (CHECK_LIB_AVAILABLE): Macro deleted.
4133 (lookup_image_type): Call define_image_type here, rather than via
4134 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
4135 (syms_of_image): Move define_image_type calls for xbm_type and
4136 pbm_type to lookup_image_type.
4138 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4140 * keyboard.c (timer_check_2): Move calculation of 'timers' and
4141 'idle_timers' from here ...
4142 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
4143 lists, to avoid infloops when the timer does something stupid,
4144 like reinvoke itself with the same or smaller time-out.
4147 2012-09-22 Martin Rudalics <rudalics@gmx.at>
4149 * window.c (Fsplit_window_internal): Handle only Qt value of
4150 Vwindow_combination_limit separately.
4151 (Qtemp_buffer_resize): New symbol.
4152 (Vwindow_combination_limit): New default value.
4155 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4157 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
4158 the new overlay string. (Bug#10159)
4160 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4162 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
4163 or that fprintf is async-signal-safe. POSIX doesn't require
4166 2012-09-22 Chong Yidong <cyd@gnu.org>
4168 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
4171 2012-09-22 Kenichi Handa <handa@gnu.org>
4173 * composite.c (composition_reseat_it): Handle the case that a
4174 grapheme cluster is not covered by a single font (Bug#12352).
4176 2012-09-21 Chong Yidong <cyd@gnu.org>
4178 * image.c (define_image_type): Avoid adding duplicate types to
4179 image_types (Bug#12463). Suggested by Jörg Walter.
4181 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4183 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
4184 (print_load_command_name): Add case LC_DATA_IN_CODE.
4185 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
4187 2012-09-21 Glenn Morris <rgm@gnu.org>
4189 * eval.c (Frun_hook_with_args_until_success)
4190 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
4192 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
4194 * fileio.c (Ffile_selinux_context): Only call freecon when
4195 lgetfilecon succeeded.
4196 (Fset_file_selinux_context): Likewise. (Bug#12444)
4198 2012-09-21 Eli Zaretskii <eliz@gnu.org>
4200 * xdisp.c (try_window_reusing_current_matrix): Under bidi
4201 reordering, locate the cursor by calling set_cursor_from_row; if
4202 that fails, clear the desired glyph matrix before returning a
4203 failure indication to the caller. Fixes leaving garbled display
4204 when fast scrolling with a down-key. (Bug#12403)
4205 (compute_stop_pos_backwards): Fix a typo that caused crashes while
4206 scrolling through multibyte text.
4208 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
4210 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
4211 calling mark_vectorlike since that's the one that marks the window.
4212 (mark_discard_killed_buffers): Mark the final cdr.
4213 * window.h (struct window): Move prev/next_buffers to the
4214 non-standard fields.
4215 * window.c (make_window): Initialize prev/next_buffers manually.
4217 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
4219 Omit unused arg EXPECTED from socket hooks.
4220 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
4221 * nsterm.m (ns_term_init):
4222 * termhooks.h (struct terminal.read_socket_hook):
4223 * w32inevt.c (w32_console_read_socket):
4224 * w32term.c (w32_read_socket):
4225 * xterm.c (XTread_socket):
4226 Omit unused arg EXPECTED. All callers changed.
4227 (store_user_signal_events): Return void, not int, since callers no
4228 longer care about the return value. All uses changed.
4230 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
4232 * w32gui.h (XParseGeometry): Do not declare.
4234 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
4236 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
4237 Ignore 'expected'. See Eli Zaretskii in
4238 <http://bugs.gnu.org/12471#8> (last line).
4240 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
4241 (XParseGeometry): Now static. Substitute extremal values for
4242 values that are out of range.
4244 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
4246 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
4248 * nsfns.m (XParseGeometry): Remove.
4249 (Fx_create_frame): Call x_set_offset to correctly interpret
4250 top_pos in geometry.
4252 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
4253 (Fx_parse_geometry): If there is a space in string, call
4254 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
4256 2012-09-17 Eli Zaretskii <eliz@gnu.org>
4258 * search.c (scan_buffer): Use character positions in calls to
4259 region_cache_forward and region_cache_backward, not byte
4260 positions. (Bug#12196)
4262 * w32term.c (w32_read_socket): Set pending_signals to 1, like
4263 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
4265 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
4266 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
4267 emacs_blocked_malloc, now deleted.
4269 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
4271 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
4272 The workaround was for improving performance on Solaris 2.4, but
4273 is getting in the way now. Emacs will still work if someone is
4274 still running Solaris 2.4 in a museum somewhere; Sun dropped
4275 support for Solaris 2.4 in 2003.
4276 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
4277 * process.c (create_process) [HAVE_WORKING_VFORK]:
4278 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
4279 since Emacs no longer uses vfork on that platform.
4281 2012-09-17 Glenn Morris <rgm@gnu.org>
4283 * emacs.c: Use COPYRIGHT.
4285 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
4287 Remove configure's --without-sync-input option (Bug#12450).
4288 When auditing signal-handling in preparation for cleaning it up,
4289 I found that SYNC_INPUT has race conditions and would be a real
4290 pain to fix. Since it's an undocumented and deprecated
4291 configure-time option, now seems like a good time to remove it.
4292 Also see <http://bugs.gnu.org/11080#16>.
4293 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
4294 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
4295 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4296 (malloc_hysteresis):
4297 (check_depth) [XMALLOC_OVERRUN_CHECK]:
4298 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
4299 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
4300 (dont_register_blocks, bytes_used_when_reconsidered)
4301 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
4302 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
4303 [!SYSTEM_MALLOC && !SYNC_INPUT]:
4304 Remove. All uses removed.
4305 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
4306 implementation, one that depends on whether the new macro
4307 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
4309 * atimer.c (run_timers, handle_alarm_signal):
4310 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
4311 (handle_async_input, process_pending_signals)
4312 (handle_input_available_signal, init_keyboard):
4313 * nsterm.m (ns_read_socket):
4314 * process.c (wait_reading_process_output):
4315 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
4316 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
4318 * xterm.c (XTread_socket):
4320 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
4321 * eval.c (handling_signal): Remove. All uses removed.
4322 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
4323 All uses replaced with the SYNC_INPUT version.
4324 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
4326 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4329 * font.c (Ffont_shape_gstring): Remove unused local.
4331 2012-09-16 Glenn Morris <rgm@gnu.org>
4333 * Makefile.in (clean): No longer run nextstep's clean.
4335 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
4337 (ns-app): Move here from ns.mk, and simplify.
4338 (clean): Simplify nextstep entry.
4339 * ns.mk: Remove file.
4341 2012-09-17 Kenichi Handa <handa@gnu.org>
4343 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
4344 not covert the last few charactes.
4346 2012-09-16 Kenichi Handa <handa@gnu.org>
4348 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
4349 here, but just check the validity of glyphs in the glyph-string.
4351 2012-09-16 Martin Rudalics <rudalics@gmx.at>
4353 * window.c (Fwindow_parameter, Fset_window_parameter):
4354 Accept any window as argument (Bug#12452).
4356 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
4358 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
4359 to ns_term_init to avoid memory leak.
4361 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
4362 explicit retain/release.
4363 (ns_term_init): Only allow one display. Initialize outerpool and
4366 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4368 Port _setjmp fix to POSIXish hosts as well as Microsoft.
4369 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
4370 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
4371 the Microsoft problem in a different way, by altering ../nt/config.nt.
4373 2012-09-15 Eli Zaretskii <eliz@gnu.org>
4388 * w16select.c: Remove inclusion of setjmp.h, as it is now included
4389 by lisp.h. This completes removal of setjmp.h inclusion
4390 erroneously announced in the previous commit. (Bug#12446)
4392 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
4395 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
4396 not defined as a macro. The latter happens on MS-Windows.
4399 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4401 Port better to POSIX hosts lacking _setjmp (Bug#12446).
4402 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
4403 Some instances of '#include <setjmp.h>' removed, if the
4404 only reason for the instance was because "lisp.h" was included.
4405 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
4406 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
4407 and _longjmp with the new symbols. Emacs already uses _setjmp if
4408 available, so this change affects only POSIXish hosts that have
4409 sigsetjmp but not _setjmp, such as some versions of Solaris and
4410 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
4411 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
4412 (png_load_body) [HAVE_PNG]:
4413 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
4414 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
4415 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
4416 since PNG requires jmp_buf. This is the only exception to the
4417 general rule that we now use sys_setjmp and sys_longjmp.
4418 This exception is OK since this code does not change the signal
4419 mask or longjmp out of a signal handler.
4421 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
4423 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4424 Include "syssignal.h", for 'main_thread'.
4426 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
4428 Avoid out-of-range marker position (Bug#12426).
4429 * insdel.c (replace_range, replace_range_2):
4430 Adjust markers before overlays, as suggested by comments.
4431 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
4432 Remove redundant check before calling offset_intervals.
4434 2012-09-14 Martin Rudalics <rudalics@gmx.at>
4436 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
4437 current buffer (Bug#12387).
4439 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
4441 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
4443 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4445 Use a more backwards-compatible timer format (Bug#12430).
4446 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
4447 vector element, not from the 4th, since PSECS is now at the end.
4448 (Fcurrent_idle_time): Doc fix.
4450 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
4452 Function to mark objects and remove killed buffers at once.
4453 * alloc.c (discard_killed_buffers): Rename to ...
4454 (mark_discard_killed buffers) ... new name. Add marking
4455 of remaining objects. Fix comment. Adjust users.
4456 (mark_object): Do not touch frame buffer lists here.
4457 * frame.c (delete_frame): Reset frame buffer lists here.
4459 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4461 Better workaround for GNOME bug when --enable-gcc-warnings.
4462 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
4463 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
4464 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
4466 Simplify SIGIO usage (Bug#12408).
4467 The code that dealt with SIGIO was crufty and confusing, e.g., it
4468 played tricks like "#undef SIGIO" but these tricks were not used
4469 consistently. Simplify mostly by not #undeffing standard symbols,
4470 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
4471 or not as we please) rather than "defined SIGIO" (standard symbol
4472 that we probably shouldn't #undef).
4473 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
4474 Modules that need it can include it.
4475 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
4476 * dispextern.h (ignore_sigio): New decl.
4477 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
4478 unconditionally, since it's now a no-op if !USABLE_SIGIO.
4479 * emacs.c (shut_down_emacs):
4480 * keyboard.c (kbd_buffer_store_event_hold):
4481 Use ignore_sigio rather than invoking 'signal' directly.
4482 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
4484 (FIONREAD, SIGIO): Do not #undef.
4485 (tty_read_avail_input): Use #error rather than a syntax error.
4486 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
4487 for I_PIPE, used by SETUP_SLAVE_PTY.
4488 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
4489 * sysdep.c (croak): Remove; no longer needed. This bit of
4490 temporary code, with Fred N. Fish's comment that it's temporary,
4491 has been in Emacs since at least 1992!
4492 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
4493 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
4494 * syssignal.h (croak): Remove decl.
4495 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
4496 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
4497 now that we're termios-only.
4498 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
4499 * term.c (dissociate_if_controlling_tty): Use #error rather than
4502 Work around GCC and GNOME bugs when --enable-gcc-warnings.
4503 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
4504 to work around GNOME bug 683906.
4505 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
4506 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
4507 This works around GCC bug 54561.
4509 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4511 More fixes for 'volatile' and setjmp/longjmp.
4512 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
4513 * image.c (struct png_load_context) [HAVE_PNG]: New type.
4514 (png_load_body) [HAVE_PNG]:
4515 (jpeg_load_body) [HAVE_JPEG]:
4516 New function, with most of the old parent function's body.
4517 (png_load) [HAVE_PNG]:
4518 (jpeg_load) [HAVE_JPEG]:
4519 Invoke the new function, to avoid longjmp munging our locals.
4520 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
4521 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
4522 longjmp is passed 2, as the C standard doesn't guarantee this.
4523 Instead, store the failure code into mgr->failure_code.
4525 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4527 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
4528 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
4529 (syms_of_keyboard): Remove support for unread-command-char.
4531 2012-09-12 Eli Zaretskii <eliz@gnu.org>
4533 * w32proc.c (sys_kill): If PID is our process ID and the signal is
4534 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
4535 violation. (Bug#12426)
4537 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4539 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
4541 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4543 * eval.c: Add `inhibit-debugger'.
4544 (Qinhibit_debugger): New symbol.
4545 (call_debugger): Bind it instead of Qdebug_on_error.
4546 (maybe_call_debugger): Test Vinhibit_debugger.
4547 (syms_of_eval): Define inhibit-debugger.
4548 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
4549 (syms_of_xdisp): Remove inhibit-debug-on-message.
4551 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4553 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
4554 If a nonvolatile local variable is written before a _longjmp to
4555 the frame containing the variable, and is read after the _longjmp,
4556 the value read is indeterminate. Some local variables of type
4557 'struct handler' and 'struct catchtag' are used in this way, so
4558 mark each of their slots as volatile if the slot can be set before
4559 _longjmp and read afterwards.
4560 * lisp.h (struct handler): var and chosen_clause are now volatile.
4561 (struct catchtag): val, next, and pdlcount are now volatile.
4563 * bidi.c (bidi_push_it, bidi_pop_it):
4564 * fns.c (copy_hash_table):
4565 * image.c (define_image_type):
4566 * keyboard.c (kbd_buffer_store_event_hold):
4567 * process.c (Fprocess_send_eof):
4568 * xfaces.c (x_create_gc) [HAVE_NS]:
4569 * xgselect.c (xg_select):
4570 Prefer assignment to memcpy when either will do.
4572 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
4573 Use pointer-to-a-pointer to simplify and avoid a NILP check each
4574 time an item is removed. No need to mark this function 'inline';
4575 the compiler knows better than we do.
4577 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
4579 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
4580 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
4581 to change_frame_size (Bug#12388).
4582 (windowDidResize:): Pass YES to updateFrameSize.
4584 * nsterm.h: Add delay parameter to updateFrameSize.
4586 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4588 Discard killed buffers from deleted window and frame objects.
4589 This reduces an amount of references to killed buffers and
4590 helps GC to reclaim them faster.
4591 * alloc.c (discard_killed_buffers): New function.
4592 (mark_object): Use it for deleted windows and frames.
4593 (mark_object): If symbol's value is set up for a killed buffer
4594 or deleted frame, restore its global binding.
4595 * data.c (swap_in_global_binding): Add GC notice.
4596 (swap_in_symval_forwarding): Use convenient set_blv_where.
4597 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
4598 * window.h: ... to here.
4600 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4602 Convenient macro to check whether the buffer is live.
4603 * buffer.h (BUFFER_LIVE_P): New macro.
4604 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
4605 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
4607 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4609 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
4610 composition cases (Bug#12364).
4612 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
4613 overhang of succeeding glyphs overlapping box cursor.
4615 * w32term.c (x_draw_glyph_string): Likewise.
4617 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4619 Simplify, document, and port floating-point (Bug#12381).
4620 The porting part of this patch fixes bugs on non-IEEE platforms
4621 with frexp, ldexp, logb.
4622 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
4624 * floatfns.c: Simplify discussion of functions that Emacs doesn't
4625 support, by removing commented-out code and briefly listing the
4626 C89 functions excluded. The commented-out stuff was confusing
4627 maintenance, e.g., we thought we needed cbrt but it was commented out.
4628 (logb): Remove decl; no longer needed.
4629 (isfinite): New macro, if not already supplied.
4630 (isnan): Don't replace any existing macro.
4631 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
4632 are present on all C89 platforms.
4633 (Ffrexp): Do not special-case zero, as frexp does the right thing
4635 (Flogb): Do not use logb, as it doesn't have the desired meaning
4636 on hosts that use non-base-2 floating point. Instead, stick with
4637 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
4638 frexp, to avoid getting an unspecified result.
4640 * xdisp.c (Qinhibit_debug_on_message): Now static.
4642 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
4644 * nsterm.m (ns_update_begin): Set clip path to whole view by using
4645 NSBezierPath (Bug#12131).
4647 2012-09-10 Chong Yidong <cyd@gnu.org>
4649 * fns.c (Fdelq, Fdelete): Doc fix.
4651 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
4653 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
4654 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
4656 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
4658 * lisp.h (make_lisp_ptr): New macro to replace XSET.
4659 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
4662 2012-09-09 Eli Zaretskii <eliz@gnu.org>
4664 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
4665 left fringe if the window has a left margin. This avoids leaving
4666 traces of the cursor because its leftmost pixel is not drawn over.
4668 * dispnew.c (update_window_line): When the left margin area of a
4669 screen line is updated, set the redraw_fringe_bitmaps_p flag of
4670 that screen line. (Bug#12277)
4672 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
4674 Assume C89 or later for math functions (Bug#12381).
4675 This simplifies the code, and makes it a bit smaller and faster,
4676 and (most important) makes it easier to clean up signal handling
4677 since we can stop worring about floating-point exceptions in
4678 library code. That was a problem before C89, but the problem
4679 went away many years ago on all practical Emacs targets.
4680 * data.c, image.c, lread.c, print.c:
4681 Don't include <math.h>; no longer needed.
4682 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
4683 might be autoconfigured, as that never happens.
4685 * doprnt.c (DBL_MAX_10_EXP):
4686 * print.c (DBL_DIG):
4687 Remove. C89 or later always defines these.
4688 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
4689 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
4690 (arith_error, domain_error, domain_error2):
4691 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
4692 no longer needed -- we simply return what C returns. All uses removed.
4693 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
4695 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
4696 Remove. All uses expanded, as these macros are no longer used
4697 more than once and are now more trouble than they're worth.
4698 (Ftan): Use tan, not sin / cos.
4699 (Flogb): Assume C89 frexp.
4700 (fmod_float): Assume C89 fmod.
4701 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
4702 (init_floatfns): Remove. All uses removed.
4704 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4706 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
4707 compositeToPoint for OSX < 10.6 (Bug#12390).
4709 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
4711 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
4712 This produces more-accurate results.
4714 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4716 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
4717 changes (Bug#12088).
4719 2012-09-08 Chong Yidong <cyd@gnu.org>
4721 * syntax.c (Fstring_to_syntax): Doc fix.
4723 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4725 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
4726 in the internal border.
4727 (x_set_window_size): Remove static variables and their usage.
4728 (ns_redraw_scroll_bars): Fix NSTRACE arg.
4729 (ns_after_update_window_line, ns_draw_fringe_bitmap):
4730 Remove fringe/internal border adjustment (Bug#11052).
4731 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
4732 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
4733 (ns_fix_rect_ibw): Remove.
4734 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
4735 (ns_dumpglyphs_box_or_relief): Ditto.
4736 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
4738 (ns_dumpglyphs_image): Ditto.
4739 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
4741 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
4742 their usage. Add fringe_extended_p and its use as in other terms.
4743 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
4744 scroll bar was removed.
4745 (updateFrameSize): New function.
4746 (windowDidResize): Move code to updateFrameSize and call it.
4748 * nsterm.h (EmacsView): Add updateFrameSize.
4750 2012-09-07 Chong Yidong <cyd@gnu.org>
4752 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
4754 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
4756 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4758 More signal-handler cleanup (Bug#12327).
4759 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
4760 Problem introduced when merging patches. Noted by Eli Zaretskii in
4761 <http://bugs.gnu.org/12327#67>.
4762 * floatfns.c: Comment fix.
4763 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
4764 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
4765 and anyway the declaration is harmless even if SIGDANGER is not defined.
4766 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
4767 defined BROKEN_FIONREAD). systty.h formerly did this, but other
4768 source files not surprisingly expected syssignal.h to define, or
4769 not define, SIGIO, and it's cleaner to do it that way, for consistency.
4770 Include <sys/ioctl.h>, for FIONREAD.
4771 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
4772 This eliminates a problem whereby other files mysteriously had
4773 to include "syssignal.h" before including "systty.h" if they
4774 wanted to use "#ifdef SIGIO".
4776 2012-09-07 Eli Zaretskii <eliz@gnu.org>
4778 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
4780 * w32.c (sigemptyset): Empty the set.
4781 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
4783 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
4785 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
4787 * alloc.c (mark_buffer): Revert unsafe marking optimization.
4788 (mark_object): Likewise for frame objects.
4790 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4792 * syssignal.h (handle_on_main_thread): Always declare,
4793 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
4794 This ports to platforms without HAVE_PTHREAD.
4796 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4798 Signal-handler cleanup (Bug#12327).
4799 Emacs's signal handlers were written in the old 4.2BSD style with
4800 sigblock and sigmask and so forth, and this led to some
4801 inefficiencies and confusion. Rewrite these to use
4802 pthread_sigmask etc. without copying signal sets around. Also,
4803 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
4804 'signal', and instead use functions that do not attempt to take
4805 over the system name space. This patch causes Emacs's text
4806 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
4807 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
4808 Do not include <signal.h> or "syssignal.h", as these
4809 modules do not use signals.
4810 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
4811 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
4812 Do not include <signal.h>, as "syssignal.h" does that for us now.
4813 * atimer.c (sigmask_atimers): New function.
4814 (block_atimers, unblock_atimers): New functions,
4815 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
4817 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
4818 no longer needed here.
4819 * emacs.c (main): Inspect existing signal handler with sigaction,
4820 so that there's no need to block and unblock SIGHUP.
4821 * sysdep.c (struct save_signal): New member 'action', replacing
4822 old member 'handler'.
4823 (save_signal_handlers, restore_signal_handlers):
4824 Use sigaction instead of 'signal' to save and restore.
4825 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
4826 New function. All users of 'signal' modified to use set_sighandler
4827 if they're writeonly, and to use sys_signal if they're read+write.
4828 (emacs_sigaction_init, forwarded_signal): New functions.
4829 (sys_signal): Remove. All uses replaced by calls to sigaction
4830 and emacs_sigaction_init, or by direct calls to 'signal'.
4831 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
4832 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
4833 all uses replaced by pthread_sigmask etc. calls.
4834 * syssignal.h: Include <signal.h>.
4835 (emacs_sigaction_init, forwarded_signal): New decls.
4836 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
4837 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
4838 (sigmask, sys_sigmask): Remove; no longer needed.
4839 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
4840 (sigblock, sigunblock, sigfree):
4841 (sigsetmask) [!defined sigsetmask]:
4842 Remove. All uses replaced by pthread_sigmask.
4843 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
4844 no longer need to be replaced, and its typical old uses
4845 are now done via emacs_sigaction_init and sigaction.
4846 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
4847 (sys_sigdel): Remove; unused.
4848 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
4850 2012-09-06 Eli Zaretskii <eliz@gnu.org>
4852 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
4853 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
4855 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4857 Explicitly mark buffer_defaults and buffer_local_symbols.
4858 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
4859 mark_local_symbols here.
4860 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
4861 since special buffers aren't marked here any more.
4862 (allocate_buffer): Chain new buffer with all_buffers here...
4863 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
4865 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
4866 (syms_of_buffer): Remove staticpro of the above.
4867 (init_buffer_once): Set names for buffer_defaults and
4868 buffer_local_symbols.
4870 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4872 Use bool for booleans in font-related modules.
4873 * font.c (font_intern_prop, font_style_to_value)

4878 (fontset_find_font, Fset_fontset_font)
4879 (face_suitable_for_char_p) [0]:
4880 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
4881 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
4882 (m17n_flt_initialized, ftfont_shape_by_flt):
4883 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
4884 * nsfont.m (nsfont_draw):
4885 * w32font.c (w32font_draw):
4886 * w32term.c (x_draw_glyphless_glyph_string_foreground):
4887 Use bool for booleans.
4888 * font.h: Adjust to above API changes.
4889 (struct font, struct font_driver, struct font_driver_list):
4890 Use bool for booleans.
4891 (struct font): Remove useless member encoding_type.
4893 * fontset.c, xftfont.c: Omit unnecessary static decls.
4895 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4897 * alloc.c (mark_object): Revert window marking code
4898 since it's unsafe for the Fset_window_configuration.
4900 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4902 Fix race conditions with signal handlers and errno (Bug#12327).
4903 Be more systematic about preserving errno whenever a signal
4904 handler returns, even if it's not in the main thread. Do this by
4905 renaming signal handlers to distinguish between signal delivery
4906 and signal handling. All uses changed.
4907 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
4908 * data.c (deliver_arith_signal): Rename from arith_error.
4909 * dispnew.c (deliver_window_change_signal): Rename from
4910 window_change_signal.
4911 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
4912 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
4913 * keyboard.c (deliver_input_available_signal): Rename from
4914 input_available_signal.
4915 (deliver_user_signal): Rename from handle_user_signal.
4916 (deliver_interrupt_signal): Rename from interrupt_signal.
4917 * process.c (deliver_pipe_signal): Rename from send_process_trap.
4918 (deliver_child_signal): Rename from sigchld_handler.
4919 * atimer.c (handle_alarm_signal):
4920 * data.c (handle_arith_signal):
4921 * dispnew.c (handle_window_change_signal):
4922 * emacs.c (handle_fatal_signal, handle_danger_signal):
4923 * keyboard.c (handle_input_available_signal):
4924 * keyboard.c (handle_user_signal, handle_interrupt_signal):
4925 * process.c (handle_pipe_signal, handle_child_signal):
4926 New functions, with the actual signal-handling code taken from the
4927 original respective signal handlers, sans the sporadic attempts to
4928 preserve errno, since that's now done by handle_on_main_thread.
4929 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
4930 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
4931 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4933 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4934 Move initialization of main_thread to sysdep.c's init_signals.
4935 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
4936 our usage, and simplifies the mainline code.
4937 (record_child_status_change): New static function, as a helper
4938 for handle_child_signal, and with most of the old child handler's
4940 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
4941 (handle_child_signal): Use the above.
4942 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4943 Moved here from emacs.c.
4944 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
4945 code moved here from emacs.c's main function.
4946 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
4947 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
4948 This lets callers save and restore errno properly.
4950 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4952 Remove redundant or unused things here and there.
4953 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
4954 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
4955 * editfns.c (Fcompare_buffer_substrings): Likewise.
4956 * frame.h (struct terminal, struct font_driver_list):
4957 Remove redundant declarations.
4958 * window.h (Qleft, Qright): Likewise.
4960 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4962 Do not mark objects from deleted buffers, windows and frames.
4963 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
4964 (mark_object): Likewise for windows and frames.
4966 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4968 * alloc.c (valid_lisp_object_p): Treat killed buffers,
4969 buffer_defaults and buffer_local_symbols as valid objects.
4970 Return special value to denote them.
4972 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4974 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
4975 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
4976 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
4977 (file_name_absolute_p, Fsubstitute_in_file_name):
4978 (check_executable, check_writable, Ffile_accessible_directory_p)

4980 (Finsert_file_contents, choose_write_coding_system)
4981 (Fwrite_region, build_annotations, a_write, e_write)
4983 * filelock.c (boot_time_initialized, get_boot_time)
4984 (get_boot_time_1, lock_file_1, within_one_second):
4985 * floatfns.c (in_float):
4986 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
4987 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
4988 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
4989 * lisp.h (struct Lisp_Hash_Table.cmpfn):
4990 * window.c (compare_window_configurations):
4991 Use bool for booleans.
4992 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
4993 (Fdefault_file_modes): Now mode_t, not int, for modes.
4994 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
4995 (internal_delete_file): Now returns void, not a (boolean) int,
4996 since nobody was looking at the return value.
4997 * lisp.h, window.h: Adjust to above API changes.
4999 * xdisp.c (set_message): Simplify and reindent last change.
5001 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
5003 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
5005 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
5007 * eval.c (call_debugger): Make the function non-static so that we
5008 can call it from set_message.
5010 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
5011 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
5013 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5015 Give more-useful info on a fatal error (Bug#12328).
5016 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
5017 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
5018 of doing the work ourselves.
5019 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
5020 do most of the work.
5021 (fatal_error_backtrace): New function, taken from the guts
5022 of the old fatal_error_signal, but with a new option to output
5024 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
5025 info about the signal than just its number.
5026 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
5027 * sysdep.c: Include <execinfo.h>
5028 (emacs_backtrace): New function, taken partly from the previous
5029 code of the 'die' function.
5030 (emacs_abort): Call fatal_error_backtrace rather than abort.
5032 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
5034 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
5035 eager (load-time) macro-expansion.
5036 * lisp.mk (lisp): Add macroexp.
5038 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5040 Simplify redefinition of 'abort' (Bug#12316).
5041 Do not try to redefine the 'abort' function. Instead, redo
5042 the code so that it calls 'emacs_abort' rather than 'abort'.
5043 This removes the need for the NO_ABORT configure-time macro
5044 and makes it easier to change the abort code to do a backtrace.
5045 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
5046 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
5047 Remove; sysdep.c's emacs_abort now takes its place.
5048 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
5049 'abort' changed to use 'emacs_abort'.
5050 * msdos.c (dos_abort) [defined abort]: Remove; not used.
5051 (abort) [!defined abort]: Rename to ...
5052 (emacs_abort): ... new name.
5053 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
5054 the place of the old 'abort' in emacs.c.
5055 * w32.c, w32fns.c (abort): Do not #undef.
5056 * w32.c (emacs_abort): Rename from w32_abort.
5058 2012-09-04 Eli Zaretskii <eliz@gnu.org>
5060 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
5061 offsets[j].dv, since the y axis of the screen coordinates points
5062 down, while the y axis of the font definition coordinates points
5063 up. This fixes display of Arabic diacritics such as KASRA and
5064 KASRATAN. (Bug#11860)
5066 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5068 Be more systematic about _setjmp vs setjmp.
5069 * alloc.c (test_setjmp, mark_stack):
5070 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
5071 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
5072 (png_load, my_error_exit, jpeg_load):
5073 * process.c (send_process_trap, send_process):
5074 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
5075 The underscored versions are up to 30x faster on some hosts.
5076 Formerly, the code used setjmp+longjmp sometimes and
5077 _setjmp+_longjmp at other times, with no particular reason to
5078 prefer setjmp+longjmp.
5080 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
5082 Fix minor problem found by static checking.
5083 * buffer.c (Fdelete_all_overlays): Return nil.
5085 2012-09-03 Martin Rudalics <rudalics@gmx.at>
5087 * buffer.c (Fdelete_all_overlays): New function.
5089 2012-09-03 Chong Yidong <cyd@gnu.org>

5109 EXCLUDE_SUBRS_P. All callers changed.
5110 * dispextern.h, lisp.h: Reflect above API changes.
5111 * firstfile.c (dummy): Use the address of 'main', whose signature
5112 won't change, instead of the address of 'initialize', whose
5113 signature just changed from int to bool.
5114 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
5115 * msdos.c (fatal_error_in_progress): ... from here.
5116 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
5118 (redisplay_internal, unwind_redisplay): Simply clear
5119 REDISPLAYING_P when unwinding, instead of saving its previous,
5120 always-false value and then restoring it.
5122 Clean up some extern decls.
5123 Mostly, this hoists extern decls out of .c files and into .h files.
5124 That way, we're more likely to catch errors if the interfaces change.
5125 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
5126 declare xg_mark_data.
5127 * dispextern.h (x_frame_parm_handlers):
5129 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)

5145 * xfont.c (x_clear_errors):
5146 * xterm.c (x_frame_parm_handlers):
5147 Remove now-redundant extern decls.
5148 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
5149 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
5151 * xfaces.c: Remove unnecessary static decls.
5152 * xterm.c (updating_frame): Remove decl of nonexistent object.
5154 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
5155 when building globals.h, as the objects that are not built on
5156 this host are not needed to compile C files on this host.
5158 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
5160 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

5198 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
5200 * makefile.w32-in (CCL_H, W32FONT_H): New macros.

5208 2012-09-01 Eli Zaretskii <eliz@gnu.org>
5210 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
5211 more than one grapheme cluster passed to the shaper: compute the
5212 offset adjustment values separately for each cluster. (Bug#11860)
5214 * image.c: Restore mistakenly removed inclusion of w32.h. Without
5215 it, GCC doesn't see prototypes of w32_delayed_load, and complains
5216 about implicit conversions from integer to pointer.
5218 2012-09-01 Daniel Colascione <dancol@dancol.org>
5220 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
5221 system used too early.
5223 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
5225 Better seed support for (random).

5274 window system declarations.
5276 * frame.h: Move common functions here: set_frame_menubar,
5277 x_set_window_size, x_sync, x_get_focus_frame,
5278 x_set_mouse_position, x_set_mouse_pixel_position,
5279 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

5306 * lisp.h (mark_ttys): Remove prototype.
5307 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
5308 to mark_ttys because all possible values of 'top_frame' slot are
5309 the frames which are reachable from Vframe_list.
5310 * term.c (mark_ttys): Remove.
5311 (init_tty): Safely initialize 'top_frame' slot with Qnil.
5313 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>

5340 * lread.c (init_lread): For out-of-tree builds, only add the
5341 source directory's site-lisp dir to the load-path if it exists,
5342 consistent with in-tree builds. (Bug#12302)
5344 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

5361 (timeout_handler:): Set timer_fired to YES.
5362 (runDialogAt:): Set timer_fired to NO.
5363 Handle click on close button as quit.
5365 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
5366 Add window_closed and button_values. Add void as return value for
5367 add(Button|String|Split). addButton takes int instead of Lisp_Object.
5368 Add process_dialog as new member.
5370 2012-08-28 Eli Zaretskii <eliz@gnu.org>
5372 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it

5483 * cmds.c (move_point, Fself_insert_command):
5484 * coding.h (struct composition status, struct coding_system):
5485 * coding.c (detect_coding_utf_8, encode_coding_utf_8)
5486 (detect_coding_utf_16, encode_coding_utf_16, detect_coding_emacs_mule)

5501 (Funencodable_char_position, code_convert_region)
5502 (code_convert_string, code_convert_string_norecord)
5503 (Fset_coding_system_priority):
5504 * fileio.c (Finsert_file_contents):
5505 Use bool for booleans.
5506 * coding.h, lisp.h: Reflect above API changes.
5507 * coding.c: Remove unnecessary static function decls.
5508 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
5509 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
5510 not a boolean 'int', since callers never look at the return value.
5511 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
5512 * coding.h (decoding_buffer_size, encoding_buffer_size)
5513 (emacs_mule_string_char): Remove unused extern decls.
5514 (struct iso_2022_spec, struct coding_system):
5515 Use 'unsigned int : 1' for boolean fields, since there's more than one.
5516 (struct emacs_mule_spec): Remove unused field 'full_support'.
5517 All initializations removed.
5518 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
5520 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
5522 Fix spare memory change (Bug#12286).
5523 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
5524 (valid_lisp_object_p): Likewise.
5526 2012-08-27 Martin Rudalics <rudalics@gmx.at>
5528 * window.c (Fset_window_configuration): Record any window's old
5529 buffer if it's replaced (see Bug#8789). If the new current
5530 buffer doesn't appear in the selected window, go to its old
5533 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
5535 Special MEM_TYPE_SPARE to denote reserved memory.
5536 * alloc.c (enum mem_type): New memory type.
5537 (refill_memory_reserve): Use new type for spare memory.
5538 This prevents live_cons_p and live_string_p from incorrect
5539 detection of uninitialized objects from spare memory as live.
5541 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
5544 * Makefile.in (.PHONY): versioclean -> versionclean.
5546 Remove unused external symbols.
5547 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
5548 * window.c (Qwindow_valid_p, decode_valid_window):
5549 Now static, not extern.
5550 * data.c (Qinterval): Remove; unused.
5551 (syms_of_data): Do not define 'interval'.
5552 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
5553 * window.h (decode_valid_window):
5556 * character.c, charset.c, chartab.c: Use bool for booleans.
5557 * character.c (lisp_string_width, string_count_byte8)
5558 (string_escape_byte8):
5559 * charset.c (charset_map_loaded, load_charset_map, read_hex):
5560 (load_charset_map_from_file, map_charset_chars)
5561 (Fdefine_charset_internal, define_charset_internal)
5562 (Fdeclare_equiv_charset, find_charsets_in_text)
5563 (Ffind_charset_region, char_charset, Fiso_charset):
5564 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
5565 (sub_char_table_set, sub_char_table_set_range)
5566 (char_table_set_range, optimize_sub_char_table)
5567 (map_sub_char_table):
5568 Use bool for boolean.
5569 * character.c (str_to_unibyte): Omit last boolean argument; it was
5570 always 0. All callers changed.
5571 * character.h, charset.h: Adjust to match previous changes.
5572 * character.h (char_printable_p): Remove decl of nonexistent function.
5573 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
5574 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
5575 are all boolean, so make them single-bit bitfields.
5577 * lisp.h (ASET): Remove attempt to detect side effects.
5578 It was meant to be temporary and it often doesn't work,
5579 because when IDX has side effects the behavior of IDX==IDX
5580 is undefined. See Stefan Monnier in
5581 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
5583 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
5585 * lisp.h (functionp): New function (extracted from Ffunctionp).
5586 (FUNCTIONP): Use it.
5587 * eval.c (Ffunctionp): Use it.
5589 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
5591 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
5592 as that's faster and simpler than static storage. Don't bother
5593 with the g_main_context_query overhead if g_main_context_pending
5594 says no events are pending.
5595 (gfds, gfds_size): Remove these static vars.
5596 (xgselect_initialize): Remove; no longer needed.
5597 All uses and decls removed.
5599 * emacs.c (fatal_error_signal_hook): Remove.
5600 All uses removed. This leftover from old code was always 0.
5602 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
5603 * casefiddle.c (casify_object, casify_region):
5604 * casetab.c (set_case_table):
5605 * category.c, category.h (word_boundary_p):
5606 * category.h (CHAR_HAS_CATEGORY):
5607 Use bool for booleans, instead of int.
5609 2012-08-25 Eli Zaretskii <eliz@gnu.org>
5611 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
5613 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
5615 On assertion failure, print backtrace if available.
5616 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
5617 (die) [ENABLE_CHECKING]: Print a backtrace if available.
5618 * Makefile.in (LIB_EXECINFO): New macro.
5621 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
5622 * bytecode.c (exec_byte_code):
5623 * callint.c (check_mark, Fcall_interactively):
5624 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
5625 (getenv_internal, sync_process_alive, call_process_exited):
5626 * lisp.h (USE_SAFE_ALLOCA):
5627 Use bool for booleans, instead of int.
5628 * lisp.h, process.h: Adjust prototypes to match above changes.
5629 * callint.c (Fcall_interactively): Don't assume the mark's
5630 offset fits in 'int'.
5632 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
5634 * buffer.c, buffer.h: Use bool for boolean.
5635 * buffer.c (reset_buffer_local_variables)
5636 (buffer_lisp_local_variables, Fset_buffer_modified_p)
5637 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
5638 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
5639 (overlay_touches_p, overlay_strings, Foverlay_put)
5640 (report_overlay_modification, call_overlay_mod_hooks):
5641 (mmap_enlarge, mmap_set_vars):
5642 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
5643 Use bool for booleans, instead of int.
5644 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
5645 since the 1-or-0 return value is always ignored anyway.
5646 (mmap_initialized_p):
5647 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
5648 * buffer.h, lisp.h: Adjust prototypes to match above changes.
5650 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5652 * bidi.c: Use bool for boolean.
5653 This is a bit more readable, and makes the text segment of bidi.o
5654 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
5655 Presumably it's faster too.
5656 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
5658 (bidi_cache_find_level_change, bidi_cache_iterator_state)
5659 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
5660 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
5661 (bidi_explicit_dir_char, bidi_level_of_next_char)
5662 (bidi_find_other_level_edge, bidi_move_to_visually_next):
5663 Use bool for booleans, instead of int.
5664 * dispextern.h (bidi_init_it, bidi_paragraph_init)
5665 (bidi_unshelve_cache): Adjust decls to match code.
5667 2012-08-23 Martin Rudalics <rudalics@gmx.at>
5669 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
5672 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5674 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
5675 * atimer.h: Include <stdbool.h>.
5677 2012-08-22 Dan Nicolaescu <dann@gnu.org>
5679 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
5680 compile time tests instead of run time tests on systems that do
5682 (FRAME_MAC_P): Remove leftover from deleted code.
5683 * frame.c (syms_of_frame): Remove leftover from deleted code.
5685 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
5687 * nsterm.m (insertText:): Don't clear modifiers if code is space.
5689 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
5691 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
5692 Otherwise, the compiler complains about (A?B:C) where B is void
5693 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
5694 (fontset_add): Return void, for FONTSET_ADD.
5696 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5698 * alloc.c: Use bool for booleans.
5699 (gc_in_progress, abort_on_gc)
5700 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5701 (dont_register_blocks) [GC_MALLOC_CHECK]:
5702 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
5703 (check_string_bytes, make_specified_string, memory_full)
5704 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
5705 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
5706 (mark_stack, valid_pointer_p, make_pure_string)
5707 (Fgarbage_collect, survives_gc_p, gc_sweep):
5708 Use bool for booleans, instead of int.
5709 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5710 Remove unused local.
5711 * alloc.c (PURE_POINTER_P):
5712 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
5713 * editfns.c (Fformat):
5714 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
5716 * fns.c (sweep_weak_table):
5717 * lisp.h (suppress_checking, push_message, survives_gc_p)
5718 (make_pure_string, gc_in_progress, abort_on_gc):
5719 * lread.c (readchar, read1):
5720 * print.c (Fprin1_to_string):
5721 * xdisp.c (push_message):
5722 Use bool for booleans affected directly or indirectly by
5725 Make recently-introduced setters macros.
5726 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
5727 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
5728 (set_fontset_default, set_fontset_fallback): Rename from their
5729 upper-case counterparts, and make them functions rather than macros.
5730 This is more consistent with the other recently-introduced setters.
5731 These don't need to be inline, since they're local.
5733 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
5735 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
5736 the loop (Bug#12247).
5738 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5740 * lisp.h (vcopy): Use memcpy rather than our own loop.
5741 This fixes a performance regression introduced by the recent
5742 addition of vcopy. This means 'vcopy' will need to be modified
5743 for a copying collector, but that's OK. Also, tighten the
5744 checking in the assertion.
5746 2012-08-21 Eli Zaretskii <eliz@gnu.org>
5748 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
5749 components for RTL text (Bug#11860). Adjust X-OFFSET of each
5750 non-base glyph for the width of the base character, according to
5751 what x_draw_composite_glyph_string_foreground expects.
5752 Generate WADJUST value according to composition_gstring_width's
5753 expectations, to produce correct width of the composed character.
5754 Reverse the sign of the DU offset produced by ScriptPlace.
5756 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5758 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
5760 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
5762 Avoid direct writes to contents member of struct Lisp_Vector.
5763 * lisp.h (vcopy): New function to copy data into vector.
5764 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
5765 * fns.c (Ffillarray): Use ASET.
5766 * keyboard.c (timer_check_2): Use AREF and ASET.
5767 (append_tool_bar_item, Frecent_keys): Use vcopy.
5768 * lread.c (read_vector): Use ASET.
5769 * msdos.c (Frecent_doskeys): Use vcopy.
5770 * xface.c (Finternal_copy_lisp_face): Use vcopy.
5771 (Finternal_merge_in_global_face): Use ASET and vcopy.
5772 * xfont.c (xfont_list_pattern): Likewise.
5774 2012-08-21 Martin Rudalics <rudalics@gmx.at>
5776 * window.c (Fwindow_point): For the selected window always return
5777 the position of its buffer's point.
5778 (Fset_window_point): For the selected window always go in its
5779 buffer to the specified position.
5781 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
5783 Setter macros for fontsets.
5784 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
5785 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
5786 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
5789 2012-08-20 Glenn Morris <rgm@gnu.org>
5791 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
5792 Don't assume that `ln -f' works.
5794 2012-08-20 Eli Zaretskii <eliz@gnu.org>
5796 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
5797 and later about non-assignments with no effect. See discussion at
5798 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
5801 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5803 Inline setter functions for Lisp_Objects slots of struct specbinding.
5804 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
5807 2012-08-20 Martin Rudalics <rudalics@gmx.at>
5809 * window.c (select_window): Always make selected window's buffer
5812 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5814 Use AREF and ASET for docstrings of category tables.
5815 * category.h (CATEGORY_DOCSTRING): Use AREF.
5816 (SET_CATEGORY_DOCSTRING): Use ASET.
5817 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
5819 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5821 Inline setter functions for hash table members.
5822 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
5823 (set_hash_hash, set_hash_index): Rename with _slot suffix.
5824 (set_hash_key_and_value, set_hash_index, set_hash_next)
5825 (set_hash_hash): New functions.
5826 * charset.c, fns.c: Adjust users.
5828 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5830 Inline getter and setter functions for per-buffer values.
5831 * buffer.h (per_buffer_default, set_per_buffer_default)
5832 (per_buffer_value, set_per_buffer_value): New functions.
5833 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
5834 * buffer.c, data.c: Adjust users.
5836 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
5838 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
5840 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
5842 Rely on <config.h> + <unistd.h> to declare 'environ',
5843 as gnulib does this if the system doesn't.
5844 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
5845 Remove declaration. MS-Windows declares it on stdlib.h which is
5846 included by conf_post.h.
5847 * emacs.c (environ) [DOUG_LEA_MALLOC]:
5848 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
5849 * vm-limit.c: Include <unistd.h>, for 'environ'.
5851 * unexaix.c, unexcoff.c: Include "mem-limits.h".
5852 (start_of_data): Remove decl; mem-limits.h provides it.
5854 * xdisp.c (handle_invisible_prop): Make it a bit faster
5855 and avoid a gcc -Wmaybe-uninitialized diagnostic.
5857 2012-08-19 Chong Yidong <cyd@gnu.org>
5859 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
5862 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
5864 * .gdbinit: Use call instead of set when calling a function in the
5867 * data.c (set_internal): Don't use set_blv_found.
5868 (Fkill_local_variable): Likewise.
5870 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
5872 * nsfont.m (ns_ascii_average_width): Ensure the string
5873 ascii_printable is initialized with a null-terminated character
5874 array. Otherwise, it can contain undesired extra characters.
5876 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
5878 port new setting code to Sun C 5.8 2005/10/13
5879 * chartab.c, lisp.h (char_table_set, char_table_set_range):
5880 Return void, not Lisp_Object. Otherwise, the compiler
5881 complains about (A?B:C) where B is void and C is Lisp_Object
5882 when compiling CHAR_TABLE_SET, due to the recent change to
5883 the API of sub_char_table_set_contents.
5885 2012-08-18 Chong Yidong <cyd@gnu.org>
5887 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
5888 for the string case (Bug#3874).
5890 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
5892 * buffer.h (BSET): Remove (Bug#12215).
5893 Replace all uses with calls to new setter functions.

6824 Fix macroexp crash on Windows with debugging (Bug#12118).
6825 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
6826 checking subscripts; problem introduced with the recent
6827 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.

6829 since it's used in non-static inline functions now.
6831 * xfaces.c (face_at_buffer_position, face_for_overlay_string):

6881 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
6883 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
6884 This how ASET and AREF are supposed to work, and makes
6885 it easier to think about future improvements. See
6886 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
6887 * charset.h (set_charset_attr): New function.

7268 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
7269 (w32_kbd_patch_key, key_event): Use the codepage returned by
7270 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.
7271 (key_event): use uChar.UnicodeChar only if
7272 w32_console_unicode_input is non-zero.

7302 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
7303 enumeration constants, as PURE and HEAP are too general, and clash
7304 with other headers and sources, such as gmalloc.c and the
7305 MS-Windows system headers. All users changed.
7307 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
7309 Revert last save_excursion_save and save_excursion_restore changes.
7310 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

7320 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
7322 Improve GDB symbol export (Bug#12036).
7323 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
7324 arms of an 'if', not using conditional expressions; otherwise GDB
7325 complains about the types in the unevaluated arm when the argument
7326 is an integer literal.
7327 (xgetint): Simplify expression.
7328 * alloc.c (gdb_make_enums_visible): New constant. This ports to
7329 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
7330 Zaretskii in <http://bugs.gnu.org/12036#13>.
7331 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
7332 needed now that we have gdb_make_enums_visible.
7333 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
7334 (enum enum_USE_LSB_TAG):
7335 New enum types, packaging up enums that need to be exported to GDB.

7354 * xfns.c (syms_of_xfns): Likewise.
7356 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>

7359 * lisp.h (struct Lisp_Excursion): New data type.
7360 (PVEC_EXCURSION): New pseudovector type.
7361 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
7362 to deal with it. Adjust comments.

7377 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
7378 emacs.c, as this is a more-suitable home. Had this been done earlier
7379 the fix for 12036 would have avoided some of the problems noted in
7380 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
7381 would have been more obvious.
7382 * emacs.c: Do not include <verify.h>; no longer needed.
7383 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
7384 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
7385 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
7386 Remove; now done in lisp.h.

7389 (DATA_SEG_BITS): Use it.
7390 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
7391 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
7392 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
7393 not be usable in #if. This simplifies things.
7395 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
7397 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
7399 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
7401 Simplify export of symbols to GDB (Bug#12036).
7402 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
7403 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
7404 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
7405 Adjust to changes in lisp.h and emacs.c, by using
7406 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
7407 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
7408 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
7409 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
7410 instead of gdb_valbits.
7411 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
7412 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
7413 instead of gdb_array_mark_flag.
7414 (xboolvector): Get size from $->size, not $->header.size.
7415 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
7416 (xreload, hook-run, hookpost-run): Remove.
7417 * emacs.c: Include <verify.h>.
7418 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
7419 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
7421 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
7422 (gdb_USE_LSB_TAG): New enum constants.
7423 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
7424 Also define these as enum constants, so they're visible to GDB.
7425 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
7426 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
7427 as constants, so they're visible to GDB.

7430 Now enum constants, not macros, so they're visible to GDB.
7431 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
7432 more convenient now. All uses changed.
7433 (VALMASK) [USE_LSB_TAG]: Also define in this case.
7434 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
7436 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

7443 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
7444 add argument, tune behavior, and adjust all callers.
7446 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
7448 Use typedef for EMACS_INT, EMACS_UINT.
7449 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
7450 than macros. This simplifies debugging in the usual case, since
7451 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
7452 and it allows expressions involving EMACS_INT casts.
7453 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
7455 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

7465 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
7467 Adjust buffer text indirection counters at the end of Fkill_buffer.
7468 * buffer.c (Fkill_buffer): Adjust indirection counters when the
7469 buffer is definitely dead. This should really fix an issue reported
7470 by Christoph Scholtes again. (Bug#12007).
7471 (init_buffer_once): Initialize indirection counters of
7472 buffer_defaults and buffer_local_symbols (for sanity and safety).
7474 2012-07-24 Eli Zaretskii <eliz@gnu.org>
7476 * xdisp.c (init_iterator): Don't compute dimensions of truncation
7477 and continuation glyphs on tooltip frames, leave them at zero.

7480 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
7482 Simplify copy_overlay.
7483 * buffer.c (copy_overlay): Simplify. Use build_marker.

7503 (build_overlay): Add prototype.
7505 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
7507 Swap buffer text indirection counters in Fbuffer_swap_text.
7508 * buffer.c (Fbuffer_swap_text): Swap indirections too.
7509 This avoids crash reported by Christoph Scholtes at
7510 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
7512 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
7514 * nsmenu.m (Popdown_data): New struct.
7515 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
7517 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
7518 (initWithContentRect): Make imgView and contentView non-static
7519 and autorelease them. Also autorelease img and matrix (Bug#12005).
7520 (dealloc): Remove (Bug#12005).
7522 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
7524 Adjust consing_since_gc when objects are explicitly freed.

7537 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
7539 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
7540 as it's limited by the amount of memory, not by INT_MAX.
7542 2012-07-21 Eli Zaretskii <eliz@gnu.org>
7544 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
7545 in special-event-map. See the discussion at

7604 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
7605 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
7606 Adjust users accordingly.
7607 * font.h (font_open_by_name): Adjust prototype.

7626 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
7627 'for_each_per_buffer_object_at'.
7628 All uses changed. It's better to use upper-case for macros that
7629 cannot be implemented as functions, to give the reader a clue
7630 that they're special.
7632 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>
7634 * alloc.c (Fgarbage_collect): Tweak docstring.

8196 2012-07-11 Glenn Morris <rgm@gnu.org>
8198 * s/bsd-common.h, s/cygwin.h: No need to undefine INTERRUPT_INPUT,
8199 since nothing has defined it on these platforms.
8201 * s/aix4-2.h, s/bsd-common.h, s/cygwin.h, s/gnu-linux.h:
8202 * s/irix6-5.h: Move SIGNALS_VIA_CHARACTERS to configure.

8213 2012-07-11 John Wiegley <johnw@newartisans.com>
8215 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
8216 function attribute, so we only use it if it exists in the
8219 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
8221 Avoid call to strlen in fast_c_string_match_ignore_case.

8223 length argument. Adjust users accordingly.
8224 * lisp.h (fast_c_string_match_ignore_case): Adjust prototype.
8226 2012-07-11 Paul Eggert <eggert@cs.ucla.edu>

8268 * s/aix4-2.h (unix): Remove; no longer needed.
8270 EMACS_TIME simplification (Bug#11875).
8271 This replaces macros (which typically do not work in GDB)
8272 with functions, typedefs and enums, making the code easier to debug.
8273 The functional style also makes code easier to read and maintain.
8274 * systime.h: Include <sys/time.h> on all hosts, not just if
8275 WINDOWSNT, since 'struct timeval' is needed in general.
8276 (EMACS_TIME): Now a typedef, not a macro.
8277 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
8279 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

8283 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
8284 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
8285 which are not functions. All uses rewritten to use:
8286 (make_emacs_time): New function.
8287 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
8288 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
8289 not functions. All uses rewritten to use the following, respectively:
8290 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
8291 (add_emacs_time, sub_emacs_time): New functions.
8292 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
8293 * fileio.c (Fcopy_file):
8294 * xterm.c (XTflash): Get the current time closer to when it's used.
8295 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

8303 * gtkutil.c (get_utf8_string):
8305 * nsmenu.m (ns_update_menubar):
8306 * regex.c (regerror):

8309 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
8310 (menu_separator_name_p):
8311 * nsmenu.m (ns_update_menubar):
8312 Prefer memcmp to strncmp when either will do.
8313 * nsterm.m: Include <ftoastr.h>.
8315 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
8316 Prefer snprintf to strncpy.
8317 * nsterm.m (ns_term_init):
8318 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
8319 * nsterm.m (ns_term_init):
8320 Avoid the need for strncpy, by using build_string or
8321 make_unibyte_string directly. Use dtoastr, not snprintf.
8322 * process.c (Fmake_network_process): Diagnose service names that
8323 are too long, rather than silently truncating them or creating
8324 non-null-terminated names.
8325 (Fnetwork_interface_info): Likewise, for interface names.
8326 * sysdep.c (system_process_attributes) [GNU_LINUX]:
8327 Prefer sprintf to strncat.
8328 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
8329 Prefer vsnprintf to vsprintf + strncpy.
8331 2012-07-10 Glenn Morris <rgm@gnu.org>
8333 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
8334 Clarify fallback case.
8336 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8338 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
8339 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
8340 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
8341 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
8342 where argument type is known to be a Lisp_Cons.
8344 2012-07-10 Tom Tromey <tromey@redhat.com>
8346 * bytecode.c (BYTE_CODE_THREADED): New macro.
8347 (BYTE_CODES): New macro. Replaces all old byte-code defines.

8354 Optimize pure C strings initialization.
8355 * lisp.h (make_pure_string): Fix prototype.
8356 (build_pure_c_string): New function, defined as static inline. This
8357 provides a better opportunity to optimize away calls to strlen when
8358 the function is called with compile-time constant argument.
8359 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
8360 argument, adjust users accordingly. Use build_pure_c_string where
8362 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
8363 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
8364 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
8366 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8368 Avoid calls to strlen in miscellaneous functions.
8369 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
8370 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
8371 * lread.c (openp): Likewise.
8373 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8375 Avoid calls to strlen in path processing functions.
8376 * fileio.c (file_name_as_directory): Add comment. Change to add
8377 srclen argument and return the length of result. Adjust users
8379 (directory_file_name): Fix comment. Change to add srclen argument,
8380 swap 1st and 2nd arguments to obey the common convention.
8381 Adjust users accordingly.
8382 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
8384 2012-07-10 Glenn Morris <rgm@gnu.org>
8386 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:

8390 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
8391 * s/gnu.h (DATA_START): Move definitions to configure.
8393 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
8394 We include usg5-4-common.h, which defines them both.
8396 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
8397 O_RDONLY already includes it).
8399 Stop ns builds setting the EMACSLOADPATH environment variable.
8400 * nsterm.m (ns_load_path): Rename from ns_init_paths.
8401 Now it does not set EMACSLOADPATH, just returns the load-path string.
8402 * nsterm.h: Update accordingly.
8403 * lread.c [HAVE_NS]: Include nsterm.h.
8404 (init_lread) [HAVE_NS]: Use ns_load_path.
8405 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
8407 2012-07-09 Glenn Morris <rgm@gnu.org>
8409 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
8410 since the included bsd-common.h does so.
8412 Stop ns builds setting the EMACSPATH environment variable.
8413 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
8414 (ns_init_paths): Do not set EMACSPATH.
8415 * nsterm.h (ns_exec_path): Add it.
8416 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
8419 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
8421 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
8423 * process.c (wait_reading_process_output): 'waitchannels' was unset
8424 when read_kbd || !NILP (wait_for_cell); fix this.
8426 Add GCC-style 'const' attribute to functions that can use it.
8427 * character.h (char_resolve_modifier_mask):
8428 * keyboard.h (make_ctrl_char):
8429 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
8430 (init_character_once, next_almost_prime, init_fns, init_image)
8431 (flush_pending_output, init_sound):
8432 * mem-limits.h (start_of_data):
8433 * menu.h (finish_menu_items):

8436 Declare the dummy function with ATTRIBUTE_CONST.
8437 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
8438 Add decls with ATTRIBUTE_CONST.
8440 Minor improvements to make_formatted_string.
8441 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
8442 where int is good enough, as vsprintf returns an int.
8443 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
8445 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8447 Use make_formatted_string to avoid double length calculation.
8448 * lisp.h (make_formatted_string): New prototype.
8449 * alloc.c (make_formatted_string): New function.
8450 * buffer.c (Fgenerate_new_buffer_name): Use it.
8451 * dbusbind.c (syms_of_dbusbind): Likewise.
8452 * editfns.c (Fcurrent_time_zone): Likewise.
8453 * filelock.c (get_boot_time): Likewise.
8454 * frame.c (make_terminal_frame, set_term_frame_name)
8455 (x_report_frame_params): Likewise.
8456 * image.c (gs_load): Likewise.
8457 * minibuf.c (get_minibuffer): Likewise.
8458 * msdos.c (dos_set_window_size): Likewise.
8459 * process.c (make_process): Likewise.

8472 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8474 Move marker debugging code under MARKER_DEBUG.
8475 * marker.c (MARKER_DEBUG): Move marker debugging code under
8476 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
8477 for bootstrap with --enable-checking (~3x slowdown reported
8478 by Juanma Barranquero <lekktu@gmail.com>).
8479 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
8481 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
8483 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
8484 See <http://bugs.gnu.org/11825#29>.
8486 2012-07-08 Eli Zaretskii <eliz@gnu.org>
8488 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
8489 has no font, use the frame's font. (Bug#11813)
8490 (display_line): Add commentary about displaying truncation glyphs
8492 (produce_special_glyphs): Move here from term.c.
8494 * term.c (produce_special_glyphs): Move to xdisp.c.
8496 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
8499 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
8501 * xdisp.c (display_line): Avoid warning about implicit declaration
8504 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
8506 * lisp.h: Remove empty conditional.
8508 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8510 * lread.c (load_path_check): Now static.
8512 Fix some minor --with-ns problems found by static checking.
8513 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
8514 (x_set_font) [!HAVE_X_WINDOWS]:
8515 * image.c (xpm_load_image) [HAVE_NS]:
8516 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
8517 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
8518 Remove unused local.
8519 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
8520 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
8521 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
8522 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
8523 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
8524 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
8525 Fix pointer signedness problem.
8526 * xfaces.c (FRAME_X_FONT_TABLE):
8527 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
8529 2012-07-07 Glenn Morris <rgm@gnu.org>
8531 * lread.c (load_path_check): New function, split from init_lread.
8532 (init_lread): Reorganize. Motivation:
8533 If EMACSLOADPATH is set, check/warn about that rather than the
8534 defaults, which we are not going to use. Hence we can remove
8535 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
8536 Don't warn if site-lisp directories are missing.
8537 If not installed, start from a blank load-path, since
8538 PATH_LOADSEARCH refers to the eventual installation directories.
8540 2012-07-07 Eli Zaretskii <eliz@gnu.org>
8542 Support truncation and continuation glyphs on GUI frames, when
8543 fringes are disabled. (Bug#11832)
8544 * xdisp.c (init_iterator): Get dimensions of truncation and
8545 continuation glyphs even if on GUI frames.
8546 Adjust it->last_visible_x on GUI frames when the left or right fringes,
8547 or both, are absent.
8548 (start_display, move_it_in_display_line_to): Handle the case of a
8549 GUI frame without a fringe to display continuation or truncation
8551 (insert_left_trunc_glyphs): Support GUI frames: make sure
8552 truncation glyphs overwrite enough glyphs from the current line to
8553 have sufficient space in pixels.
8554 (display_line): Support truncation and continuation glyphs on GUI
8555 frames. If some spare pixels are left on the line after inserting
8556 the truncation glyphs, fill that space with a stretch glyph of a
8557 suitably computed width.
8559 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
8560 produce_glyphs, to support GUI sessions.
8562 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8564 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
8566 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
8568 Do not require float-time's arg to fit in time_t (Bug#11825).
8569 This works better on hosts where time_t is unsigned, and where
8570 float-time is applied to the (negative) difference between two times.
8571 * editfns.c (decode_time_components): Last arg is now double *,
8572 not int *, and means to store all the result as a double, without
8573 worrying about whether the seconds part fits in time_t.
8574 All callers changed.
8575 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
8576 All callers changed.
8577 (Ffloat_time): Do not fail merely because the specified time falls
8578 outside of time_t range.

8622 * process.c: Avoid unnecessary calls to gettime.
8623 (wait_reading_process_output): Don't get the time of day
8624 when gobbling data immediately and not waiting, as there's no need
8625 for it in that case. This removes a FIXME.
8627 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
8629 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3

8640 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8642 Compile marker debugging code only if ENABLE_CHECKING is defined.
8643 * marker.c (byte_char_debug_check, count_markers):
8644 Use only if ENABLE_CHECKING is defined.
8645 (byte_debug_flag): Remove.
8646 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8647 Always call byte_char_debug_check if ENABLE_CHECKING is defined.

8689 Port to OpenBSD 5.1 amd64.
8690 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
8691 This is needed for OpenBSD, and should be harmless on all BSD systems.
8692 Also, include <sys/sysctl.h>, as it should be available on all
8693 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
8694 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
8695 use p_pid member, not kp_proc.pid.
8697 2012-07-06 Glenn Morris <rgm@gnu.org>
8699 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
8701 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

8712 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
8714 Omit needless casts involving void * pointers and allocation.
8715 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
8716 as the former is more robust if P's type is changed.
8717 Prefer xzalloc to xmalloc + memset 0.
8718 Simplify malloc-or-realloc to realloc.
8719 Don't worry about xmalloc returning a null pointer.
8720 Prefer xstrdup to xmalloc + strcpy.
8721 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
8723 * keyboard.c (apply_modifiers_uncached): Prefer local array to
8724 alloca of a constant.

8728 * xdisp.c (display_line): Fix horizontal pixel coordinates when
8729 hscroll is larger than the line width. Fixes long and futile
8730 looping inside extend_face_to_end_of_line (on a TTY) producing
8731 glyphs that are not needed and thrown away.
8733 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>

8749 followed by gtk_box_set_homogeneous (Bug#11768).
8750 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
8751 (update_theme_scrollbar_width, xg_create_scroll_bar):
8752 Use gtk_scrollbar_new (Bug#11768).

8761 * xdisp.c (window_hscroll_limited): New function.
8762 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
8763 coordinates when window's hscroll is set to insanely large
8766 2012-07-05 Juanma Barranquero <lekktu@gmail.com>

8835 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
8836 This should be fixed in a better way; see Eli Zaretskii in
8837 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
8838 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
8840 * fileio.c (time_error_value): Rename from special_mtime.
8841 The old name's problems were noted by Eli Zaretskii in
8842 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
8844 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
8845 This variable's comment says Emacs needs at least one GDB-visible
8846 symbol of type enum pvec_type, to work around GDB problems.
8847 The symbol's value doesn't matter.
8849 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
8850 that causes compilation to fail on pre-C99 compilers.
8852 2012-07-04 Juanma Barranquero <lekktu@gmail.com>

8880 abusing vector->header.next.nbytes.
8881 (live_vector_p): Use PVEC_TYPE.
8882 (mark_object): Adapt code to extract pvectype. Use switch.
8884 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>

8891 Fix compilation with --enable-gcc-warnings and -O1
8893 * doprnt.c (doprnt): Change type of tem to int, initialize
8894 to avoid compiler warning. Add eassert.
8895 * search.c (simple_search): Initialize match_byte to avoid
8896 compiler warning. Add eassert.
8898 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8900 Avoid weird behavior with large horizontal scrolls.
8901 Without this change, for example, large hscroll values would
8902 mess up Emacs's display on Fedora 15 x86, presumably due to
8903 overflows in int calculations in the display code.
8904 Also, if buffers had long lines, Emacs would freeze.
8905 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
8906 (set_window_hscroll): New function, containing the old guts of
8907 Fset_window_hscroll. Return the clipped value.
8908 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.

8920 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
8921 since GCC 4.4.6 issues a bogus warning for them.
8923 Fix bugs in file timestamp newness comparisons.
8924 * fileio.c (Ffile_newer_than_file_p):
8925 * lread.c (Fload): Use full timestamp resolution of files,
8926 not just the 1-second resolution, so that files that are only
8927 slightly newer still count as newer.
8928 * fileio.c (Ffile_newer_than_file_p): Don't assume file
8929 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
8931 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
8933 * fileio.c: Improve handling of file time marker. (Bug#11852)

8940 * fileio.c (Finsert_file_contents): Properly handle st_mtime
8941 marker for non-existing file. (Bug#11852)
8943 2012-07-03 Glenn Morris <rgm@gnu.org>
8945 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
8946 and did not make it into globals.h).
8948 2012-07-03 Tom Tromey <tromey@redhat.com>

9037 and related comments.
9039 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
9041 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
9042 wrapper that is not needed because the wrapped code is a no-op (zero
9043 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
9044 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
9046 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
9048 * alloc.c (mark_buffer): Simplify. Remove prototype.
9049 (mark_object): Add comment. Reorganize marking of vector-like
9050 objects. Use CHECK_LIVE for all vector-like objects except buffers
9051 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
9052 Avoid redundant calls to mark_vectorlike for bool vectors.
9054 2012-06-30 Glenn Morris <rgm@gnu.org>
9056 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
9058 * epaths.in (PATH_SITELOADSEARCH): New.
9059 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
9060 This is rather than relying on --enable-locallisppath elements
9061 having "site-lisp" in their names. (Bug#10208#25, 11658)
9063 2012-06-30 Eli Zaretskii <eliz@gnu.org>
9065 * w32proc.c (sys_select): Accept and ignore one more argument.
9067 * w32.c (emacs_gnutls_pull): Call select with one more argument.
9069 * sysselect.h [DOS_NT]: Don't include sys/select.h.
9070 (pselect) [!MS_DOS]: Redirect to sys_select.
9072 * sysdep.c: Don't include dos.h and dosfns.h.
9074 * process.c (sys_select):
9075 * msdos.c (sys_select): Accept one more argument and ignore it.
9077 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
9078 adapt data types and code to that.
9081 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
9082 which clashes with the gnulib function of the same name.
9084 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
9086 * font.c (font_style_to_value, font_style_symbolic)
9087 (font_prop_validate_style): Add type checks for values in
9090 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
9092 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
9095 2012-06-29 Eli Zaretskii <eliz@gnu.org>
9097 * xdisp.c (try_window_id): Undo last change.
9099 * w32.c (getwd): Adjust commentary about startup_dir.
9100 (init_environment): Always call sys_access, even in non-MSVC
9101 builds. Don't chdir to the directory of the Emacs executable.
9102 This undoes code from 1997 which was justified by the need to
9103 "avoid conflicts when removing and renaming directories". But its
9104 downside was that every relative file name was being interpreted
9105 relative to the directory of the Emacs executable, which can never
9106 be TRT. In particular, it broke sys_access when called with
9107 relative file names.
9108 (sys_access): Map GetLastError to errno.
9110 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9112 * window.h (struct window): Change type of 'fringes_outside_margins'
9113 to bitfield. Fix comment. Adjust users accordingly.
9114 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
9116 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
9119 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
9121 * gnutls.c (emacs_gnutls_handshake):
9122 Add QUIT to make the loop interruptible.
9124 2012-06-29 Glenn Morris <rgm@gnu.org>
9126 * charset.c (init_charset): Make lack of etc/charsets fatal.
9128 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9130 * editfns.c (region_limit): Fix type mismatch.
9132 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9134 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
9135 undefined. Convert from xassert to eassert.
9136 * nsmenu.m: Convert from xassert to eassert.
9137 * nsterm.m: Likewise.
9139 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
9141 * editfns.c (region_limit): Clip to narrowing (bug#11770).
9143 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
9145 Avoid integer overflow on scroll-left and scroll-right.
9146 * window.c (HSCROLL_MAX): New macro.
9147 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
9148 overflow when requested scroll falls outside ptrdiff_t range.
9150 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9152 * window.h (struct window): Change type of 'hscroll',
9153 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
9154 'last_modified' and 'last_overlay_modified' to EMACS_INT.
9155 Adjust users accordingly.
9156 * xdisp.c (try_cursor_movement): Replace type check with eassert.
9157 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
9158 from EMACS_INT to ptrdiff_t.
9159 (make_window): Omit redundant initialization.
9161 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
9163 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
9165 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9167 * window.h (struct window): Change type of 'use_time' and
9168 'sequence_number' from Lisp_Object to int.
9169 * frame.c (make_frame): Adjust users accordingly.
9170 * print.c (print_object): Likewise.
9171 * window.c (select_window, Fwindow_use_time, make_parent_window)
9172 (make_window): Likewise.
9174 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9176 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
9177 enabled with --enable-checking=[all,glyphs] configure option.
9178 Fix GLYPH_DEBUG usage assuming that it may be undefined,
9179 adjust comments accordingly.

9226 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
9228 * alloc.c (allocate_string_data): Remove dead code.
9229 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to
9230 avoid GCC warning about unused macro.
9232 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
9234 * alloc.c (allocate_string): Omit intervals initialization.
9235 * alloc.c (make_uninit_multibyte_string): Initialize intervals
9236 as in make_pure_string and make_pure_c_string.
9238 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
9240 * alloc.c (allocate_string): Fix last change.
9242 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
9244 * alloc.c (allocate_string): Remove two redundant calls
9245 to memset, add explicit initialization where appropriate.
9247 2012-06-27 Glenn Morris <rgm@gnu.org>
9249 * lisp.mk (lisp): Remove paths.elc.
9251 2012-06-27 Chong Yidong <cyd@gnu.org>
9253 * doc.c (Fsubstitute_command_keys): Fix punctuation.
9255 2012-06-26 John Wiegley <johnw@newartisans.com>
9257 * unexmacosx.c (copy_data_segment): Add two section names used
9258 on Mac OS X Lion: __mod_init_func and __mod_term_func.
9260 * alloc.c (mark_memory): Do not check with -faddress-sanitizer
9261 when building with Clang.
9263 2012-06-26 Stefan Monnier <monnier@iro.umontreal.ca>
9265 * eval.c (Fapply): Allow calling it with a single argument.
9267 2012-06-26 Eli Zaretskii <eliz@gnu.org>
9269 * s/ms-w32.h (strcasecmp, strncasecmp) [_MSC_VER]: Redirect to
9270 _stricmp and _strnicmp.
9271 (HAVE_STRCASECMP, HAVE_STRNCASECMP): Define to 1.
9273 2012-06-26 Dmitry Antipov <dmantipov@yandex.ru>
9275 * alloc.c (allocate_window): Zero out non-Lisp part of newly
9277 (allocate_process): Likewise for new process.
9278 (allocate_terminal): Change to use offsetof.
9279 (allocate_frame): Likewise.
9280 * frame.c (make_frame): Omit redundant initialization.

9288 * term.c (delete_tty): Remove redundant call to memset.
9290 2012-06-26 Dmitry Antipov <dmantipov@yandex.ru>
9292 * alloc.c: Remove build_string.
9293 * lisp.h: Define build_string as static inline. This provides
9294 a better opportunity to optimize away calls to strlen when the
9295 function is called with compile-time constant argument.
9296 * image.c (imagemagick_error): Convert to build_string.
9297 * w32proc.c (sys_spawnve): Likewise.
9298 * xterm.c (x_term_init): Likewise.
9300 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
9302 Use sprintf return value instead of invoking strlen on result.
9303 In the old days this wasn't portable, since some sprintf
9304 implementations returned char *. But they died out years ago and
9305 Emacs already assumes sprintf returns int.
9306 Similarly for float_to_string.
9307 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
9308 * ccl.c (ccl_driver):
9309 * character.c (string_escape_byte8):
9310 * data.c (Fnumber_to_string):
9311 * doprnt.c (doprnt):
9312 * print.c (print_object):
9313 * xdisp.c (message_dolog):
9314 * xfns.c (syms_of_xfns):
9315 Use sprintf or float_to_string result to avoid need to call strlen.
9316 * data.c (Fnumber_to_string):
9317 Use make_unibyte_string, since the string must be ASCII.
9318 * lisp.h, print.c (float_to_string): Now returns int length.
9319 * term.c (produce_glyphless_glyph):
9320 Use sprintf result rather than recomputing it.
9322 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
9323 * Makefile.in (ALL_CFLAGS):
9324 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
9325 * gmalloc.c, regex.c: Include <config.h> unconditionally.
9327 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
9329 * dispextern.h (xstrcasecmp): Define to library function
9330 strcasecmp if available.
9331 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.
9333 2012-06-25 Andreas Schwab <schwab@linux-m68k.org>
9335 * keyboard.c (menu_bar_items, menu_bar_item, read_key_sequence):
9336 Avoid comma operator.
9337 * menu.c (push_submenu_start, push_submenu_end)
9338 (push_left_right_boundary, push_menu_pane): Likewise.

9346 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
9348 * gtkutil.c (get_utf8_string): Remove redundant assignment.
9349 sprintf already null-terminates its output.
9351 * xfns.c (x_window): Remove redundant cast.
9353 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
9355 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
9356 `const char *' to `char *' to avoid compiler warning.
9358 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
9360 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
9361 instead of truncating it to 63 (admittedly a generous limit).
9363 * process.c: Fix spelling and caps in comments.
9365 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
9367 * emacs.c (setpgrp): Remove definition, unused.
9368 * sysdep.c (setpgrp): Remove definition, not used in this file.

9377 (SYSTIME_H): Add nt/inc/sys/time.h.
9379 * systime.h [WINDOWSNT]: Include sys/time.h.
9381 * s/ms-w32.h (struct timespec): Definition moved from
9382 nt/inc/sys/time.h. Suggested by Paul Eggert <eggert@cs.ucla.edu>.
9384 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
9386 Switch from NO_RETURN to C11's _Noreturn (Bug#11750).

9410 * xterm.c (x_ins_del_lines, x_delete_glyphs):
9411 Use _Noreturn rather than NO_RETURN.
9412 No need for separate decl merely because of _Noreturn.
9413 * sound.c (sound_warning, parse_sound):
9414 Remove unnecessary forward decls.
9416 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
9418 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
9419 * lisp.h (WAIT_READING_MAX): New macro.
9420 * dispnew.c (Fsleep_for, sit_for):
9421 * keyboard.c (kbd_buffer_get_event):
9422 * process.c (Faccept_process_output):
9423 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
9424 This improves on the previous patch, which introduced a bug
9425 when time_t is unsigned and as wide as intmax_t.
9426 See <http://bugs.gnu.org/9000#51>.
9428 2012-06-23 Eli Zaretskii <eliz@gnu.org>
9430 * dispnew.c (sit_for, Fsleep_for):
9431 * keyboard.c (kbd_buffer_get_event):
9432 * process.c (Faccept_process_output): Avoid compiler warnings when
9433 comparing a 32-bit time_t with a 64-bit INTMAX_MAX.
9435 2012-06-23 Juanma Barranquero <lekktu@gmail.com>
9437 * makefile.w32-in: Update dependencies.
9439 * w32.c (ltime): Add return type and declare static.
9440 (w32_get_internal_run_time): Remove usused variable `time_100ns'.
9442 2012-06-23 Paul Eggert <eggert@cs.ucla.edu>
9444 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
9445 Privately reported by Herbert J. Skuhra.
9446 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
9448 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
9449 not make_lisp_timeval, when the argument is of type EMACS_TIME.
9451 2012-06-23 Eli Zaretskii <eliz@gnu.org>
9453 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
9454 last argument of make_unibyte_string.
9456 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
9457 language ID in the event parameters.
9459 * w32term.c (w32_read_socket): Put the new keyboard codepage into
9460 event.code, not the obscure "character set ID".
9462 2012-06-23 Chong Yidong <cyd@gnu.org>
9464 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.
9466 2012-06-23 Eli Zaretskii <eliz@gnu.org>
9468 Fix the MS-Windows build broken by 2012-06-22T21:17:42Z!eggert@cs.ucla.edu.
9469 * w32.c (fdutimens): New function.
9471 * w32proc.c (sys_select): Adapt to change in the EMACS_TIME type.
9473 * s/ms-w32.h (pselect): Redirect to sys_select.
9475 * sysselect.h [WINDOWSNT]: Don't include sys/select.h.

9478 in the logic of incrementing and decrementing the value of
9479 use_relocatable_buffers.
9481 2012-06-23 Paul Eggert <eggert@cs.ucla.edu>
9483 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
9484 Privately reported by Herbert J. Skuhra.
9485 [__FreeBSD__]: Remove "*/" typo after "#include".
9486 (timeval_to_EMACS_TIME) [__FreeBSD__]: New static function.
9487 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.

9489 Don't assume EMACS_TIME and struct timeval are the same type.
9491 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
9493 Support higher-resolution time stamps (Bug#9000).
9494 The time stamps are only nanosecond-resolution at the C level,
9495 since that's the best that any real-world system supports now.
9496 But they are picosecond-resolution at the Lisp level, as that's
9497 easy, and leaves room for future OS improvements.
9499 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
9502 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
9503 Don't get current time unless it's needed.
9505 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
9506 now provides it if it's absent.
9507 (start_atimer): Port to higher-res time stamps.
9508 Check for time stamp overflow. Don't get current time more
9509 often than is needed.
9511 * buffer.h (struct buffer): Buffer modtime now has high resolution.
9512 Include systime.h, not time.h.
9513 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
9515 * dired.c: Include stat-time.h.
9516 (Ffile-attributes): File times now have higher resolution.
9518 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
9519 (struct image): Timestamp now has higher resolution.
9521 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
9522 has at least microseconds now. All uses removed.
9523 (update_frame, update_single_window, update_window, update_frame_1)
9524 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
9525 (duration_to_sec_usec): Remove; no longer needed.
9527 * editfns.c (time_overflow): Now extern.
9528 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
9529 (float-time, Fformat_time_string, Fcurrent_time_string)
9530 (Fcurrent_time_zone): Accept and generate higher-resolution
9532 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
9533 (decode_time_components, lisp_seconds_argument): New functions.
9534 (make_time): Now static.
9535 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
9536 Report an error if the time is invalid, rather than having the caller
9539 * fileio.c: Include <stat-time.h>
9540 (Fcopy_file): Copy higher-resolution time stamps.

9558 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
9559 Port to higher-resolution time stamps. Do not assume time_t is signed.
9560 (decode_timer): New function. Timers are now vectors of length 9,
9561 not 8, to accommodate the picosecond component.
9562 (timer_check_2): Use it.
9564 * nsterm.m (select_timeout, timeval_subtract): Remove.
9565 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
9566 as they're a bit more accurate and handle overflow better.
9567 (ns_select): Change prototype to be compatible with pselect.
9568 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
9569 * nsterm.h (ns_select): Adjust prototype.
9571 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
9572 us-resolution time stamps.
9573 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
9575 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
9577 * lisp.h (time_overflow): New decl.
9578 (wait_reading_process_output): First arg is now intmax_t, not int,
9579 to accommodate larger waits.
9581 * process.h (struct Lisp_Process.read_output_delay):
9582 Now counts nanoseconds, not microseconds.
9583 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about

9588 (Faccept_process_output, wait_reading_process_output):
9589 Check for time stamp overflow. Do not assume time_t is signed.
9590 (select_wrapper): Remove; we now use pselect.
9591 (Fprocess_attributes): Now generates ns-resolution time stamps.
9593 * sysdep.c: Include utimens.h. Don't include utime.h
9594 or worry about struct utimbuf; gnulib does that for us now.
9595 (gettimeofday): Remove; gnulib provides a substitute.
9596 (make_timeval): New function.
9597 (set_file_times): Now sets ns-resolution time stamps.
9598 New arg FD; all uses changed.
9599 (time_from_jiffies, ltime_from_jiffies, get_up_time)

9601 Now returns ns-resolution time stamp. All uses changed.
9602 Check for time stamp overflow.
9604 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
9605 provides a substitute now.
9607 * systime.h: Include timespec.h rather than sys/time.h and time.h,
9608 since it guarantees struct timespec.
9609 (EMACS_TIME): Now struct timespec, so that we can support
9610 ns-resolution time stamps.
9611 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
9612 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
9613 (EMACS_USECS): Remove.
9614 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
9615 so multiply the arg by 1000 before storing it.
9616 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
9618 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):

9625 (make_timeval, make_lisp_time, decode_time_components): New decls.
9626 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
9627 that it mishandled time_t overflow. You can't compare by subtracting!
9628 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
9629 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
9631 * term.c: Include <sys/time.h>.
9632 (timeval_to_Time): New function, for proper overflow wraparound.
9633 (term_mouse_position, term_mouse_click): Use it.
9635 * undo.c (record_first_change): Support higher-resolution time stamps
9637 (Fprimitive_undo): Use them when restoring time stamps.
9639 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
9640 (w32_get_internal_run_time):
9641 Port to higher-resolution Emacs time stamps.
9642 (ltime): Now accepts single 64-bit integer, as that's more convenient

9647 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
9648 for compatibility with pselect. Support ns-resolution time stamps.

9652 * xselect.c (wait_for_property_change, x_get_foreign_selection):
9653 Check for time stamp overflow, and support ns-resolution time stamps.
9655 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
9656 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
9657 (timeval_subtract): Remove; no longer needed.
9658 (XTflash, XTring_bell, x_wait_for_event):
9659 Port to ns-resolution time stamps. Don't assume time_t is signed.

9665 2012-06-22 Eli Zaretskii <eliz@gnu.org>
9667 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
9668 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
9669 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
9670 staticidx goes up to 1597 out of 1600 = 0x640.)
9672 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
9674 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
9675 Otherwise, the umask might be mistakenly 0 while handling input signals.
9677 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
9679 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

9685 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
9686 access to `contents' member of Lisp_Vector objects with AREF and ASET
9689 2012-06-19 Chong Yidong <cyd@gnu.org>
9691 * frame.c (delete_frame): When selecting a frame on a different
9692 text terminal, do not alter the terminal's top-frame.

9697 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
9699 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
9700 since tty frames can be explicitly named.
9701 (prepare_menu_bars): Likewise.
9703 * term.c (Ftty_top_frame): New function.
9705 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

9708 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
9709 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
9710 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
9711 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

9718 2012-06-18 Martin Rudalics <rudalics@gmx.at>
9720 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
9721 gets killed during executing of this function (Bug#11665).
9722 Try to always return Qt when the buffer has been actually killed.
9723 (Vkill_buffer_query_functions): In doc-string say that functions
9724 run by this hook should not change the current buffer.
9726 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
9728 Fix recently-introduced process.c problems found by static checking.
9729 * process.c (write_queue_push, write_queue_pop, send_process):

9746 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
9748 * lisp.h (eassert): Assume C89 or later.
9749 This removes the need for CHECK.
9750 (CHECK): Remove. Its comments about always evaluating its
9751 argument were confusing, as 'eassert' typically does not evaluate
9754 * coding.c (produce_chars): Use ptrdiff_t, not int.
9756 * xterm.c (x_draw_underwave): Check for integer overflow.
9757 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

9850 * xdisp.c (set_cursor_from_row): Don't dereference glyphs_end.
9851 If all the glyphs of the glyph row came from strings, and we have no
9852 cursor positioning clues, put the cursor on the first glyph of the

10032 * xdisp.c (vmessage): Treat frame message as multibyte.
10033 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
10034 would generate the diagnostic "Making \302\247 buffer-local while

10061 Block-based vector allocation of small vectors.
10062 * lisp.h (struct vectorlike_header): New field `nbytes',
10063 adjust comment accordingly.
10064 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
10065 to denote vector blocks. Adjust users (live_vector_p,
10066 mark_maybe_pointer, valid_lisp_object_p) accordingly.

10088 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
10090 * doprnt.c (doprnt): Truncate multibyte char correctly.
10091 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
10092 would mishandle a string argument "Xc" if X was a multibyte
10093 character of length 2: it would truncate after X's first byte
10094 rather than including all of X.
10096 2012-06-06 Chong Yidong <cyd@gnu.org>
10098 * buffer.c (word_wrap): Doc fix.
10100 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

10112 binary via PaX flags if the paxctl utility is available.
10113 (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
10114 Restore PaX flags to their default. (Bug#11398)
10116 2012-06-03 Chong Yidong <cyd@gnu.org>
10118 * xdisp.c (decode_mode_spec_coding): Display a space for a unibyte
10119 buffer (Bug#11226).

10126 position is past the end of the mode line string.
10128 * buffer.c (buffer_local_value_1): New function, split from
10129 Fbuffer_local_value; can return Qunbound.
10130 (Fbuffer_local_value): Use it.
10131 (Vmode_line_format): Docstring tweaks.
10133 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>

10145 * minibuf.c (Fassoc_string): Remove duplicate declaration.
10147 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
10148 Convert pctcpu and pctmem to Lisp float properly.
10149 Let the compiler fold better, as 100.0/0x8000 is exact.
10151 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
10153 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
10156 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>

10160 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
10162 For a 'struct window', replace some Lisp_Object fields to
10163 bitfields where appropriate, remove unused fields.
10164 * window.h (struct window): Remove unused 'last_mark_x' and
10165 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
10166 change its type from Lisp_Object to bitfield.
10167 Change type of 'force_start', 'optional_new_start',
10168 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
10169 fields from Lisp_Object to bitfield. Adjust users accordingly.
10171 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10173 Pacify gcc -Wdouble-precision when using Xaw.
10174 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
10175 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
10176 Use 'float' consistently, rather than 'float' in most places
10177 and 'double' in a couple of places.
10179 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10181 * xdisp.c (handle_stop): Detect whether we have overlay strings
10182 loaded by testing it->current.overlay_string_index to be
10183 non-negative, instead of checking whether n_overlay_strings is
10184 positive. (Bug#11587)
10186 2012-05-31 Chong Yidong <cyd@gnu.org>
10188 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

10192 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10194 * search.c (search_buffer): Remove calls to
10195 r_alloc_inhibit_buffer_relocation, as it is now called by
10196 maybe_unify_char, which was the cause of relocation of buffer text
10199 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10201 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
10202 for the duration of call to load_charset, to avoid problems with
10203 callers of maybe_unify_char that access buffer text through C
10206 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
10207 decrement the inhibition flag, instead of just setting or
10210 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10212 Remove obsolete '#define static' cruft.
10213 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
10214 This #undef was "temporary" in 2000; it is no longer needed
10215 now that '#define static' has gone away.
10216 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
10217 (gray_bitmap_bits): Remove; no longer needed.
10218 All uses replaced with definiens.
10219 * xterm.c: Include "bitmaps/gray.xbm".
10221 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
10223 Clean up __executable_start, monstartup when --enable-profiling.
10224 The following changes affect the code only when profiling.
10225 * dispnew.c (__executable_start): Rename from safe_bcopy.
10226 Define only on platforms that need it.
10227 * emacs.c: Include <sys/gmon.h> when profiling.
10228 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
10229 (__executable_start): Remove decl, since lisp.h does it now.
10230 (safe_bcopy): Remove decl; no longer has that name.
10231 (main): Coalesce #if into single bit of code, for simplicity.
10232 Cast pointers to uintptr_t, since standard libraries want integers
10234 * lisp.h (__executable_start): New decl.
10236 2012-05-31 Glenn Morris <rgm@gnu.org>
10238 * image.c (Fimagemagick_types): Doc fix.

10259 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
10261 Do not create empty overlays with the evaporate property (Bug#9642).
10262 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
10263 Bug#9642, but explicitly check that the buffer the overlay would
10264 be moved to is live and rearrange lines to make sure that errors
10265 will not put the overlay in an inconsistent state.
10266 (Fdelete_overlay): Cosmetics.
10268 2012-05-28 Eli Zaretskii <eliz@gnu.org>
10270 * w32term.c (my_bring_window_to_top): New function.
10271 (x_raise_frame): Use handle returned by DeferWindowPos, which
10272 could be different from the original one.
10273 Call my_bring_window_to_top instead of my_set_foreground_window.

10282 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
10284 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
10285 This avoids undefined behavior that might cause the eassert
10286 to not catch an out-of-range value.
10288 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
10290 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
10291 Update dependencies.
10293 2012-05-27 Eli Zaretskii <eliz@gnu.org>
10295 * bidi.c (bidi_mirror_char): Fix last change.
10297 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>

10302 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
10304 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
10305 Only r_alloc_inhibit_buffer_relocation needed to be added;
10306 the others were already declared.
10308 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
10309 before checking whether it's out of range. Put the check inside
10311 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
10313 2012-05-27 Ken Brown <kbrown@cornell.edu>
10315 * callproc.c (Fcall_process): Restore a line that was accidentally
10316 commented out in the 2011-02-13 change (bug#11547).
10318 2012-05-27 Eli Zaretskii <eliz@gnu.org>
10320 * lisp.h [REL_ALLOC]: Add prototypes for external functions
10321 defined on ralloc.c.
10323 * buffer.c [REL_ALLOC]: Remove prototypes of
10324 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
10325 they are now on lisp.h.
10327 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
10329 * search.c (search_buffer): Use it to inhibit relocation of buffer
10330 text while re_search_2 is doing its job, because re_search_2 is
10331 passed C pointers to buffer text. (Bug#11519)
10333 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
10334 Update value to 24.
10336 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
10337 state after an additional call to move_it_in_display_line_to, keep
10338 the values of it->max_ascent and it->max_descent found for the
10340 (pos_visible_p): Revert the comparison against bottom_y to what it
10341 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
10344 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10346 Fix coding-related core dumps with gcc -ftrapv.
10347 The code was computing A - B, where A and B are pointers, and B is
10348 random garbage. This can lead to core dumps on platforms that
10349 have special pointer registers, and it also leads to core dumps on
10350 x86-64 when compiled with gcc -ftrapv. The fix is to compute
10351 A - B only when B is initialized properly.
10352 * coding.c (coding_set_source, coding_set_destination): Return void.
10353 (coding_change_source, coding_change_destinations): New functions,
10354 with the old behaviors of coding_set_source and coding_set_destination.
10355 All callers that need an offset changed to use these new functions.
10357 2012-05-26 Glenn Morris <rgm@gnu.org>
10359 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)

10365 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
10367 * w32console.c: Include window.h.
10368 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
10370 (initialize_w32_display): Initialize mouse-highlight data.
10372 * w32inevt.c: Include termchar.h and window.h.
10373 (do_mouse_event): Support mouse-autoselect-window. When the mouse
10374 moves, call note_mouse_highlight. If help_echo changed, call
10375 gen_help_event to produce help-echo message in the echo area.
10376 Call clear_mouse_face if mouse_face_hidden is set in the mouse
10379 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10381 * lread.c (read1): Simplify slightly to avoid an overflow warning
10382 with GCC 4.7.0 on x86-64.
10384 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10386 * bidi.c (bidi_mirror_char): Revert last change: an int is
10387 definitely wide enough here.
10389 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
10391 Fix integer width and related bugs (Bug#9874).

10398 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
10399 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
10401 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10402 (allocate_pseudovector):
10403 Use int, not EMACS_INT, where int is wide enough.
10404 (inhibit_garbage_collection, Fgarbage_collect):
10405 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10406 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
10407 int might not be wide enough.
10408 (bidi_cache_search, bidi_cache_find, bidi_init_it)
10409 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
10410 (bidi_at_paragraph_end, bidi_find_paragraph_start)
10411 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
10412 (bidi_level_of_next_char, bidi_move_to_visually_next):
10413 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10414 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
10415 (Fkill_buffer, Fset_buffer_major_mode)
10416 (advance_to_char_boundary, Fbuffer_swap_text)
10417 (Fset_buffer_multibyte, overlays_at, overlays_in)
10418 (overlay_touches_p, struct sortvec, record_overlay_string)
10419 (overlay_strings, recenter_overlay_lists)
10420 (adjust_overlays_for_insert, adjust_overlays_for_delete)
10421 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)

10423 (Foverlay_recenter, last_overlay_modification_hooks_used)
10424 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
10425 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10426 (validate_region): Omit unnecessary test for b <= e,
10427 since that's guaranteed by the previous test.
10428 (adjust_overlays_for_delete): Avoid pos + length overflow.
10429 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
10430 (report_overlay_modification):
10431 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10432 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
10433 Omit pointer cast, which isn't needed anyway, and doesn't work
10434 after the EMACS_INT -> ptrdiff_t change.
10435 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
10436 * buffer.h: Adjust decls to match defn changes elsewhere.
10437 (struct buffer_text, struct buffer):
10438 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10439 Use EMACS_INT, not int, where int might not be wide enough.
10440 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
10441 not int, to avoid needless 32-bit limit on 64-bit hosts.
10442 (exec_byte_code): Use tighter memory-full test, one that checks
10443 for alloca overflow. Don't compute the address of the object just
10444 before an array, as that's not portable. Use EMACS_INT, not
10445 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
10446 * callint.c (Fcall_interactively):
10447 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10448 * callproc.c (call_process_kill, Fcall_process):
10449 Don't assume pid_t fits into an Emacs fixnum.

10460 (casify_object): Avoid integer overflow when overallocating buffer.
10461 * casetab.c (set_identity, shuffle): Prefer int to unsigned when

10464 * category.h (CATEGORYP): Don't assume arg is nonnegative.
10465 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the

10469 For CCL_MapSingle, check that content and value are in int range.
10470 (ccl_driver, Fregister_code_conversion_map):
10471 Check that Vcode_version_map_vector is a vector.
10472 (resolve_symbol_ccl_program): Check that vector header is in range.
10473 Always copy the vector, so that we can check its contents reliably
10474 now rather than having to recheck each instruction as it's being
10475 executed. Check that vector words fit in 'int'.
10476 (ccl_get_compiled_code, Fregister_ccl_program)
10477 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
10478 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

10491 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

10504 Don't rely on undefined behavior with signed left shift overflow.
10505 Don't assume unsigned int fits into fixnum, or that fixnum fits
10506 into unsigned int. Don't require max_code to be a valid fixnum;
10507 that's not true for gb10830 4-byte on a 32-bit host. Allow
10508 invalid_code to be a cons, for the same reason. Require code_offset
10509 to be a character. Avoid int overflow if max_char is close
10511 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
10512 this is intended anyway and avoids some undefined behavior.
10513 (load_charset_map): Pass unsigned, not int, as 2nd arg of
10514 INDEX_TO_CODE_POINT, as that's what it expects.
10515 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
10516 * charset.h (DECODE_CHAR): Return int, not unsigned;

10519 integer-overflow issues.
10520 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
10521 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
10522 where the argument is EMACS_INT, and this behavior is not intended.
10523 * chartab.c (Fmake_char_table, Fset_char_table_range)
10524 (uniprop_get_decoder, uniprop_get_encoder):
10525 Don't assume fixnum fits in int.
10526 * cmds.c (move_point): New function, that does the gist of
10527 Fforward_char and Fbackward_char, but does so while checking
10528 for integer overflow more accurately.
10529 (Fforward_char, Fbackward_char): Use it.
10530 (Fforward_line, Fend_of_line, internal_self_insert)

11134 (last_escape_glyph_face_id, last_glyphless_glyph_face_id):
11135 (handle_tool_bar_click):
11136 Use int, not unsigned, since we prefer signed and the signedness
11137 doesn't matter here.
11138 (get_next_display_element, next_element_from_display_vector):
11139 Use int, not EMACS_INT, when int is wide enough.
11140 (start_hourglass): Use duration_to_sec_usec to do proper
11141 overflow checking on durations.
11142 * xfaces.c (Fbitmap_spec_p):
11143 Check that fixnums are in proper range for system types.

11179 * xterm.c (x_x_to_emacs_modifiers):
11180 Don't assume EMACS_INT overflows nicely into int.
11181 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
11182 may come from Lisp.
11183 (handle_one_xevent): NATNUMP can eval its arg twice.
11184 (x_connection_closed):
11185 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11186 * xterm.h: Adjust decls to match defn changes elsewhere.
11187 (struct scroll_bar): Use struct vectorlike_header
11188 rather than rolling our own approximation.

11191 2012-05-25 Glenn Morris <rgm@gnu.org>
11193 * lisp.mk (lisp): Update for more files being compiled now.
11195 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
11197 * lread.c: Remove `read_pure' which makes no difference.
11198 (read_pure): Remove var.
11199 (unreadpure): Remove function.
11200 (readevalloop): Don't call read_list with -1 flag.
11201 (read1, read_vector): Don't test read_pure any more.
11202 (read_list): Simplify.
11204 * fileio.c, character.h: Minor style tweaks.

11210 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
11212 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
11213 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
11215 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
11218 This directory predates autoconf and is no longer needed nowadays.
11219 Move its few remaining bits of functionality to where they're needed.
11220 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
11221 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
11222 * m/template.h: Remove.
11223 * Makefile.in (M_FILE): Remove. All uses removed.
11224 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
11225 * lisp.h (USE_LSB_TAG):
11226 * mem-limits.h (EXCEEDS_LISP_PTR):
11227 Use VAL_MAX, not VALBITS, in #if.
11228 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
11229 (EMACS_UINT): Define unconditionally now.
11230 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
11231 (BITS_PER_EMACS_INT): New constants, replacing
11232 what used to be in config.h, but not useful in #if.
11233 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
11234 define them any more.
11235 (VAL_MAX): New macro.
11237 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
11238 BITS_PER_EMACS_INT, in #if.
11239 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
11240 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
11241 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
11242 * s/ms-w32.h (DATA_START):
11243 Move here from removed file m/intel386.h.
11244 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
11245 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
11247 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
11249 Assume C89 or later.
11250 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
11251 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
11253 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.

11259 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
11260 * xterm.c (input_signal_count): Assume volatile works.
11262 2012-05-21 Ken Brown <kbrown@cornell.edu>
11264 * xgselect.c (xg_select): Fix first argument in call to 'select'
11267 2012-05-20 Ken Brown <kbrown@cornell.edu>
11269 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
11270 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
11272 2012-05-19 Ken Brown <kbrown@cornell.edu>
11274 * xfns.c (x_in_use): Remove `static' qualifier.
11275 * xterm.h (x_in_use): Declare.
11276 * xgselect.c: Include xterm.h.
11277 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
11278 and `display_arg' (bug#9754).
11280 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
11282 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
11284 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
11285 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
11287 2012-05-18 Eli Zaretskii <eliz@gnu.org>
11289 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
11291 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
11292 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
11294 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
11295 reference to image_cache->refcount.
11296 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
11298 2012-05-17 Juri Linkov <juri@jurta.org>
11300 * search.c (Fword_search_regexp, Fword_search_backward)
11301 (Fword_search_forward, Fword_search_backward_lax)
11302 (Fword_search_forward_lax): Move functions to isearch.el
11303 (bug#10145, bug#11381).
11305 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
11307 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
11309 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
11311 * lread.c (init_obarray): Declare Qt and Qnil as special.
11313 2012-05-14 Glenn Morris <rgm@gnu.org>
11315 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
11316 Put "libexec" before "bin", for the sake of init_callproc_1.
11318 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11320 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
11322 * unexaix.c: Port to more-recent AIX compilers.
11323 (report_error, report_error_1, make_hdr, copy_sym)
11324 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
11325 Make arguments const char *, not char *, to avoid violations of C
11326 standard and to fix some AIX warnings reported by Gilles Pion.
11328 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11330 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
11331 already have overlays loaded.
11332 (handle_single_display_spec): Before returning without displaying
11333 fringe bitmap, synchronize the bidi iterator with the main display
11334 iterator, by calling iterate_out_of_display_property.
11335 (iterate_out_of_display_property): Detect buffer iteration by
11336 testing that it->string is a Lisp string.
11337 (get_next_display_element): When the current object is exhausted,
11338 and there's something on it->stack, call set_iterator_to_next to
11339 proceed with what's on the stack, instead of returning zero.
11340 (set_iterator_to_next): If called at the end of a Lisp string,
11341 proceed to consider_string_end without incrementing string
11342 position. Don't increment display vector index past the end of
11343 the display vector. (Bug#11417)
11344 (pos_visible_p): Don't report a position visible when move_it_to
11345 stopped at the last line of window, which happens to be scanned
11346 backwards by the bidi iteration. (Bug#11464)
11348 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11350 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
11351 and right-margin display specs even if the spec is invalid or we
11352 are on a TTY, and thus unable to display on the fringes.
11353 That's because the text with the property will not be displayed anyway,
11354 so we need to signal to the caller that this is a "replacing"
11355 display spec. This fixes display when the spec is invalid or we
11358 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11360 * unexaix.c (make_hdr): Fix typo in prototype.
11361 This bug broke the build on AIX. Problem reported by Gilles Pion.
11363 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
11365 * keyboard.c (kbd_buffer_get_event): Read special events also in
11366 batch mode. (Bug#11415)
11368 2012-05-12 Glenn Morris <rgm@gnu.org>
11370 * ns.mk: Update for ns_appbindir no longer having trailing "/".
11372 2012-05-12 Eli Zaretskii <eliz@gnu.org>
11374 * lisp.mk (lisp): Add newcomment.elc.
11376 2012-05-12 Glenn Morris <rgm@gnu.org>
11378 * Makefile.in (MKDIR_P): New, set by configure.
11379 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
11381 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
11383 Remove unused function hourglass_started.
11384 * dispextern.h (hourglass_started):
11385 * w32fns.c (hourglass_started):
11386 * xdisp.c (hourglass_started): Remove.
11388 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
11390 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
11391 Update dependencies.
11393 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
11395 * xgselect.c (xg_select): Put maxfds+1 into a var.
11396 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
11398 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
11400 2012-05-10 Dave Abrahams <dave@boostpro.com>
11402 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
11403 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
11405 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
11407 * dbusbind.c (xd_registered_buses): New internal Lisp object.
11408 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
11409 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
11410 Initialize xd_registered_buses.
11412 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
11414 Untag more efficiently if USE_LSB_TAG.
11415 This is based on a proposal by YAMAMOTO Mitsuharu in
11416 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
11417 For an admittedly artificial (nth 8000 longlist) benchmark on
11418 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
11419 Emacs's overall text size by 1%.
11420 * lisp.h (XUNTAG): New macro.
11421 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
11422 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
11423 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
11424 * eval.c (Fautoload):
11425 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
11426 * frame.h (XFRAME): Use XUNTAG.
11428 Port recent dbusbind.c changes to 32-bit --with-wide-int.
11429 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
11430 Remove unportable assumptions about print widths of types like
11432 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
11433 intptr_t when converting between pointer and integer, to avoid GCC
11434 warnings about wrong width.
11436 2012-05-09 Eli Zaretskii <eliz@gnu.org>
11438 * w32proc.c (new_child): Force Windows to reserve only 64KB of
11439 stack for each reader_thread, instead of defaulting to 8MB
11440 determined by the linker. This avoids failures in creating
11441 subprocesses on Windows 7, see the discussion in this thread:
11442 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
11444 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
11446 Fix up display of the *Minibuf-0* buffer in the mini window.
11447 * keyboard.c (read_char): Don't clear the echo area if there's no
11449 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
11450 contents of *Minibuf-0*) if there's no message displayed in its stead.
11452 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
11454 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
11457 2012-05-06 Chong Yidong <cyd@gnu.org>
11459 * lisp.mk (lisp): Update.
11461 2012-05-05 Jim Meyering <meyering@redhat.com>
11463 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
11465 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
11467 * data.c (PUT_ERROR): New macro.
11468 (syms_of_data): Use it. Add new error type `user-error'.
11469 * undo.c (user_error): New function.
11470 (Fprimitive_undo): Use it.
11471 * print.c (print_error_message): Adjust print style for `user-error'.
11472 * keyboard.c (user_error): New function.
11473 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
11475 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
11477 Do not limit current-time-string to years 1000..9999.
11478 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
11479 (Fcurrent_time_string): Support any year that is supported by the
11480 underlying localtime representation. Don't use asctime, as it
11481 has undefined behavior for years outside the range -999..9999.
11483 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
11485 Fix race conditions involving setenv, gmtime, localtime, asctime.
11486 Without this fix, interrupts could mess up code that uses these
11487 nonreentrant functions, since setting TZ invalidates existing
11488 tm_zone or tzname values, and since most of these functions return
11489 pointers to static storage.
11490 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
11491 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
11492 Grow the critical sections to include not just invoking
11493 localtime/gmtime, but also accessing these functions' results
11494 including their tm_zone values if any, and any related TZ setting.
11495 (format_time_string): Last arg is now struct tm *, not struct tm **,
11496 so that the struct tm is saved in the critical section.
11497 All callers changed. Simplify allocation of initial buffer, partly
11498 motivated by the fact that memory allocation needs to be outside
11499 the critical section.
11501 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
11503 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
11504 with RESET_INTERVAL.
11506 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
11507 Remove duplicated buffer name initialization.
11509 2012-05-02 Jim Meyering <jim@meyering.net>
11511 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
11513 * xfns.c (x_window): Use xstrdup (Bug#11375).
11515 2012-05-02 Eli Zaretskii <eliz@gnu.org>
11517 * xdisp.c (pos_visible_p): If already at a newline from the
11518 display string before the 'while' loop, don't walk back the glyphs
11519 from it3.glyph_row. Solves assertion violation when the display
11520 string begins with a newline (egg.el). (Bug#11367)
11522 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
11524 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
11527 2012-05-01 Glenn Morris <rgm@gnu.org>
11529 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
11530 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
11531 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
11532 All were removed before 23.1.
11534 * dispnew.c: Remove HAVE_LIBNCURSES test;
11535 it is always true on relevant platforms.
11537 * Makefile.in (LD_SWITCH_X_SITE_RPATH):

11550 Do not avoid creating empty evaporating overlays (Bug#9642).
11551 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
11552 That is, do not delete an evaporating overlay if it becomes
11553 empty after its bounds are adjusted to fit within its buffer.
11554 This fix caused other problems, and I'm reverting it until we get
11555 to the bottom of them.
11557 2012-04-27 Chong Yidong <cyd@gnu.org>
11559 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
11561 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11563 * xdisp.c (pos_visible_p): If the window start position is beyond
11564 ZV, start the display from buffer beginning. Prevents assertion
11565 violation in init_iterator when the minibuffer window is scrolled
11566 via the scroll bar.
11568 * window.c (window_scroll_pixel_based): Likewise.
11570 2012-04-27 Chong Yidong <cyd@gnu.org>

11584 2012-04-26 Eli Zaretskii <eliz@gnu.org>
11586 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
11587 display element, check also the underlying string or buffer
11588 character. (Bug#11341)
11590 * w32menu.c: Include w32heap.h.
11591 (add_menu_item): If the call to AppendMenuW (via
11592 unicode_append_menu) fails, disable Unicode menus only if we are
11593 running on Windows 9X/Me.
11595 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
11597 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
11598 (xgetint): Add missing shift for LSB tags.
11600 2012-04-24 Martin Rudalics <rudalics@gmx.at>
11602 * keyboard.c (read_char): Don't wipe echo area for select window
11603 events: These might get delayed via `mouse-autoselect-window'

11608 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
11609 manipulation of :loaded-from data.
11611 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
11613 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
11614 now a cons (bug#11311).
11616 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
11618 Do not create empty overlays with the evaporate property (Bug#9642).
11619 * buffer.c (Fmove_overlay): Delete an evaporating overlay
11620 if it becomes empty after its bounds are adjusted to fit within
11621 its buffer. Without this fix, in a nonempty buffer (let ((o
11622 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
11623 yields an empty overlay that has the evaporate property, which is
11624 not supposed to happen.

11962 the buffer at position that is closer to point than the position
11963 after the display string, display the cursor on the first glyph of
11964 the display string. Fixes cursor display when a 'display' text
11965 property immediately follows invisible text. (Bug#11094)
11967 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
11969 composite.c: use 'double' consistently
11970 * composite.c (get_composition_id): Use 'double' consistently
11971 instead of converting 'float' to 'double' and vice versa; this is
11972 easier to understand and avoids a GCC warning.
11974 2012-04-09 Glenn Morris <rgm@gnu.org>
11976 * Makefile.in: Generate leim-list with bootstrap-emacs, in
11977 preparation for dumping it with emacs. (Bug#4789)
11978 (leimdir): New variable.
11979 ($(leimdir)/leim-list.el): New rule.
11980 (emacs$(EXEEXT)): Depend on leim-list.el.
11982 * buffer.c (Qucs_set_table_for_input): Remove. (Bug#9821)
11983 (Fget_buffer_create): Don't call Qucs_set_table_for_input.

11998 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
11999 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
12000 (mark_memory): Mark Lisp_Objects only if pointers might hide in
12001 objects, as mark_maybe_pointer will catch them otherwise.
12002 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
12003 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
12005 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
12007 Fix typo that broke non-Windows builds.
12008 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
12010 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12012 Support building on MS-Windows with libxml2.
12014 * makefile.w32-in (OBJ2): Add xml.$(O).
12015 (GLOBAL_SOURCES): Add xml.c.
12016 ($(BLD)/xml.$(O)): New dependency list.
12018 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
12019 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
12020 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
12021 [!WINDOWSNT]: New macros.
12022 (init_libxml2_functions, libxml2_loaded_p): New functions.
12023 (parse_region): Call fn_xmlCheckVersion instead of using the macro
12024 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
12025 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
12026 Calls xmlCleanupParser only if libxml2 was loaded (or statically
12028 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
12029 Call init_libxml2_functions before calling libxml2 functions.
12030 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
12032 * emacs.c: Don't include libxml/parser.h.
12033 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
12034 xmlCleanupParser directly.
12036 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
12038 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12040 * indent.c (Fvertical_motion): If there is a display string at
12041 point, use it.vpos to compute how many lines to backtrack after
12042 move_it_to point. (Bug#11133)
12044 2012-04-06 Eli Zaretskii <eliz@gnu.org>
12046 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
12047 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
12048 about subtle differences between FETCH_CHAR* and STRING_CHAR*
12049 macros related to unification of CJK characters. For the details,
12050 see the discussion following the message here:
12051 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
12053 2012-04-04 Chong Yidong <cyd@gnu.org>
12055 * keyboard.c (Vdelayed_warnings_list): Doc fix.
12057 2012-04-01 Eli Zaretskii <eliz@gnu.org>
12059 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
12060 instead of alloca. (Bug#11138)
12062 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
12064 * w32menu.c (is_simple_dialog): Properly check lisp types.
12067 2012-03-31 Eli Zaretskii <eliz@gnu.org>
12069 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
12070 position we get to after a call to move_it_to fails the
12071 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
12072 only if we wind up in a string from display property. (Bug#11063)
12074 * window.c (Fdelete_other_windows_internal): Invalidate the row
12075 and column information about mouse highlight, so that redisplay
12076 restores it after reallocating the glyph matrices. (Bug#7464)
12078 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
12079 string comes from a `display' text property, use the buffer
12080 position of that property as if we actually saw that position in
12082 (move_it_by_lines): Remove the assertion that
12083 "it->current_x == 0 && it->hpos == 0" which can be legitimately
12084 violated when there's a before-string at the beginning of a line.
12087 2012-03-30 Eli Zaretskii <eliz@gnu.org>
12089 * xdisp.c (append_space_for_newline): If the default face was
12090 remapped, use the remapped face for the appended newline.
12091 (extend_face_to_end_of_line): Use the remapped default face for
12092 extending the face to the end of the line.
12093 (display_line): Call extend_face_to_end_of_line when the default
12094 face was remapped. (Bug#11068)
12096 2012-03-29 Eli Zaretskii <eliz@gnu.org>
12098 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
12100 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
12102 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
12104 2012-03-27 Glenn Morris <rgm@gnu.org>
12106 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
12109 2012-03-26 Kenichi Handa <handa@m17n.org>
12111 * dispextern.h (struct glyph): Fix previous change. Change the
12112 bit length of glyphless.ch to 25 (Bug#11082).
12114 2012-03-26 Chong Yidong <cyd@gnu.org>
12116 * keyboard.c (Vselection_inhibit_update_commands): New variable.
12117 (command_loop_1): Use it; inhibit selection update for
12118 handle-select-window too (Bug#8996).
12120 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
12122 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
12124 2012-03-25 Kenichi Handa <handa@m17n.org>
12126 * dispextern.h (struct glyph): Change the bit length of
12127 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
12129 2012-03-24 Eli Zaretskii <eliz@gnu.org>
12131 * s/ms-w32.h (tzname): Include time.h before redirecting to
12132 _tzname. Fixes the MSVC build. (Bug#9960)
12134 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
12136 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
12139 * xterm.c (XTread_socket): Only modify handling_signal if
12140 !SYNC_INPUT. (Bug#11080)
12142 2012-03-23 Eli Zaretskii <eliz@gnu.org>
12144 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
12145 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
12146 when fetching a multibyte character consumes more bytes than
12147 CHAR_BYTES returns, due to unification of CJK characters in
12148 string_char. (Bug#11073)
12150 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
12152 * process.c (wait_reading_process_output): Handle pty disconnect
12153 by refraining from sending oneself a SIGCHLD (bug#10933).

12160 Mark string as coming from a prefix property.
12161 (handle_face_prop): Use default face for prefix strings (Bug#4281).
12162 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
12164 2012-03-21 Chong Yidong <cyd@gnu.org>
12166 * xfaces.c (Vface_remapping_alist): Doc fix.
12168 2012-03-20 Eli Zaretskii <eliz@gnu.org>
12170 * w32proc.c (Fw32_set_console_codepage)
12171 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
12174 2012-03-20 Chong Yidong <cyd@gnu.org>
12176 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
12177 to reflect default non-nil value of redisplay-dont-pause.
12179 2012-03-19 Kenichi Handa <handa@m17n.org>
12181 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
12182 it fit in a valid range (Bug#11003).
12184 2012-03-18 Eli Zaretskii <eliz@gnu.org>
12186 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
12187 that is not from display property, accept the row as a "cursor
12188 row" if one of the string's character has a non-nil `cursor'
12189 property. Fixes cursor positioning when there are newlines in
12190 overlay strings, e.g. in icomplete.el. (Bug#11035)
12192 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
12194 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
12196 2012-03-12 Chong Yidong <cyd@gnu.org>
12198 * eval.c (inhibit_lisp_code): Rename from
12199 inhibit_window_configuration_change_hook; move from window.c.
12201 * xfns.c (unwind_create_frame_1, Fx_create_frame):
12202 * window.c (run_window_configuration_change_hook)
12203 (syms_of_window): Callers changed.
12205 2012-03-11 Chong Yidong <cyd@gnu.org>

12209 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
12211 2012-03-10 Chong Yidong <cyd@gnu.org>
12213 * frame.c (other_visible_frames): Don't assume the selected frame
12214 is visible (Bug#10955).
12216 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
12218 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).

12222 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
12223 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
12226 2012-03-03 Glenn Morris <rgm@gnu.org>
12228 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
12230 2012-03-02 Eli Zaretskii <eliz@gnu.org>
12232 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
12233 position past the first glyph_row that ends at ZV. (Bug#10902)
12234 (redisplay_window, next_element_from_string): Fix typos in
12236 (redisplay_window): Pass to move_it_vertically the margin in
12237 pixels, not in screen lines.
12239 2012-03-02 Glenn Morris <rgm@gnu.org>
12241 * buffer.c (buffer-list-update-hook): Doc fix.
12243 2012-02-29 Eli Zaretskii <eliz@gnu.org>
12245 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
12246 push_it before setting up the iterator for the first overlay
12247 string, even if we have an empty string loaded.
12248 (next_overlay_string): If there's an empty string on the iterator
12249 stack, pop the stack. (Bug#10903)
12251 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
12253 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
12254 Suggested by Stefan Monnier in
12255 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
12256 * alloc.c (widen_to_Lisp_Object): New static function.
12257 (mark_memory): Also mark Lisp_Objects by fetching pointer words
12258 and widening them to Lisp_Objects. This would work even if
12259 USE_LSB_TAG is defined and wide integers are used, which might
12260 happen in a future version of Emacs.
12262 2012-02-25 Chong Yidong <cyd@gnu.org>
12264 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
12267 * xselect.c (Fx_selection_exists_p): Doc fix.

12269 before saving to clipboard manager.
12271 2012-02-24 Chong Yidong <cyd@gnu.org>
12273 * keyboard.c (process_special_events): Handle all X selection
12274 requests in kbd_buffer, not just the next one (Bug#8869).
12276 2012-02-23 Chong Yidong <cyd@gnu.org>
12278 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
12279 call when setting menu-bar-lines and tool-bar-lines parameters.
12280 (unwind_create_frame_1): New helper function.
12282 * window.c (inhibit_window_configuration_change_hook): New var.
12283 (run_window_configuration_change_hook): Obey it.
12284 (syms_of_window): Initialize it.
12286 2012-02-22 Chong Yidong <cyd@gnu.org>

12301 when computing $valmask.
12303 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
12304 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
12305 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
12306 It's useless in that case, and it can cause problems on hosts
12307 that allocate halves of EMACS_INT values separately.
12308 Reported by Dan Horák. Diagnosed by Andreas Schwab in
12309 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
12310 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
12311 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
12312 it avoids undefined behavior on hosts where shifting right by more
12313 than the word width has undefined behavior.
12315 2012-02-19 Chong Yidong <cyd@gnu.org>
12317 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
12318 (Funhandled_file_name_directory, Ffile_name_as_directory)
12319 (Fdirectory_file_name, Fexpand_file_name)
12320 (Fsubstitute_in_file_name): Protect against invalid file handler
12321 return values (Bug#10845).
12323 2012-02-18 Eli Zaretskii <eliz@gnu.org>

12335 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
12337 2012-02-15 Chong Yidong <cyd@gnu.org>
12339 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
12340 marked as special. Also, starting docstrings with * is obsolete.

12355 2012-02-12 Chong Yidong <cyd@gnu.org>
12357 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
12358 as that creates a dangerous corner case.
12360 * window.c (Fdelete_window_internal): Invalidate the mouse
12361 highlight (Bug#9904).
12363 2012-02-12 Glenn Morris <rgm@gnu.org>

12366 (Fx_get_selection_internal, Fx_disown_selection_internal)
12367 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
12368 * nsselect.m (Fx_own_selection_internal)
12369 (Fx_disown_selection_internal, Fx_selection_exists_p)
12370 (Fx_selection_owner_p, Fx_get_selection_internal):
12371 Sync docs and argument specs with the xselect.c versions.
12373 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
12375 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
12377 2012-02-11 Eli Zaretskii <eliz@gnu.org>
12379 * w32select.c (Fx_selection_exists_p): Sync doc string and
12380 argument list with xselect.c. (Bug#10783)
12382 * w16select.c (Fx_selection_exists_p): Sync doc string and

12393 2012-02-07 Chong Yidong <cyd@gnu.org>
12395 * buffer.c (Fbuffer_local_variables)
12396 (buffer_lisp_local_variables): Handle unbound vars correctly;
12397 don't let Qunbound leak into Lisp.
12399 2012-02-07 Glenn Morris <rgm@gnu.org>
12401 * image.c (Fimagemagick_types): Doc fix.
12403 * image.c (imagemagick-render-type): Change it from a lisp object
12404 to an integer. Move the doc here from the lisp manual.
12405 Treat all values not equal to 0 the same.
12407 2012-02-06 Chong Yidong <cyd@gnu.org>
12409 * doc.c (store_function_docstring): Avoid applying docstring of
12410 alias to base function (Bug#2603).
12412 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>

12424 Include --enable-checking, if specified, in the return value.
12426 2012-02-04 Martin Rudalics <rudalics@gmx.at>
12428 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
12429 after rounding frame sizes. (Bug#9723)
12431 2012-02-04 Eli Zaretskii <eliz@gnu.org>
12433 * keyboard.c (adjust_point_for_property): Don't position point
12434 before BEGV. (Bug#10696)
12436 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
12438 Handle overflow when computing char display width (Bug#9496).
12439 * character.c (char_width): Return EMACS_INT, not int.
12440 (char_width, c_string_width): Check for overflow when

12930 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
12931 verifies glyph row's hash code--we have just reallocated the
12932 glyphs, so their contents can be complete garbage. (Bug#10164)

12977 * lisp.h (GCTYPEBITS): Move before first use.
12978 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
12979 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in
12980 this macro definition.
12982 * s/ms-w32.h (tzname): Redirect to _tzname for all values of
12985 2011-11-27 Jan Djärv <jan.h.d@swipnet.se>

13007 * xdisp.c (redisplay_window): If cursor row is not fully visible
13008 after recentering, and scroll-conservatively is set to a large
13009 number, scroll window by a few more lines to make the cursor fully
13010 visible and out of scroll-margin. (Bug#10105)
13011 (start_display): Don't move to the next line if the display should
13012 start at a newline that is part of a display vector or an overlay
13013 string. (Bug#10119)
13015 2011-11-24 Juri Linkov <juri@jurta.org>

13041 and header-lines, as they don't have one computed for them.
13044 * .gdbinit (prow): Make displayed values more self-explaining.
13045 Add row's hash code.

13093 Otherwise, valgrind does not work on some platforms.
13094 Problem reported by Andreas Schwab in
13095 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
13096 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
13097 is set, removing the need for VIRT_ADDRESS_VARIES.
13098 (PURE_P): Use a more-efficient implementation that needs just one
13099 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
13100 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
13101 to 4 (xorl, subq, cmpq, setbe).
13102 * alloc.c (pure): Always extern now, since that's the
13103 VIRT_ADDR_VARIES behavior.
13104 (PURE_POINTER_P): Use a single comparison, not two, for
13105 consistency with the new puresize.h.
13106 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
13107 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

13113 (erase_phys_cursor, update_window_cursor, show_mouse_face)
13114 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
13115 behave as if the cursor position were at the window margin.
13117 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
13118 and the cursor position is out of bounds, behave as if the cursor
13119 position were at the window margin. (Bug#10075)
13121 2011-11-18 Chong Yidong <cyd@gnu.org>
13123 * window.c (Fwindow_combination_limit): Make first argument
13124 non-optional, since it is meaningless for live windows like the

13139 hash values of the two rows.
13140 (copy_row_except_pointers): Preserve the used[] arrays and the
13141 hash values of the two rows. (Bug#10035)
13142 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
13144 * xdisp.c (row_hash): New function, body extracted from
13145 compute_line_metrics.
13146 (compute_line_metrics): Call row_hash, instead of computing the
13149 * dispnew.c (verify_row_hash): Call row_hash for computing the
13150 hash code of a row, instead of duplicating code from xdisp.c.
13152 * dispextern.h (row_hash): Add prototype.
13154 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
13156 * frame.c (delete_frame): Don't delete the terminal when the last

13182 (Fsplit_window_internal, saved_window)
13183 (Fset_window_configuration, save_window_save): Rename all
13184 occurrences of window_nest to window_combination_limit.
13186 2011-11-15 Juanma Barranquero <lekktu@gmail.com>

13190 2011-11-14 Eli Zaretskii <eliz@gnu.org>
13192 * xdisp.c (display_line): Move the call to
13193 highlight_trailing_whitespace before the call to
13194 compute_line_metrics, since the latter needs to see the final
13195 faces of all the glyphs to compute ROW's hash value.
13196 Fixes assertion violations in row_equal_p. (Bug#10035)
13198 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
13200 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

13203 2011-11-12 Eli Zaretskii <eliz@gnu.org>
13205 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
13206 with user-defined heap size. Bump the default size of the temacs
13207 heap to 27MB, to avoid memory warning when running temacs.
13208 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
13210 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
13211 current_matrix and desired_matrix. (Bug#9990)
13212 (verify_row_hash) [XASSERTS]: New function.
13213 (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify
13214 that the hash value of glyph rows is correct.

13243 2011-11-11 Johan Bockgård <bojohan@gnu.org>
13245 * xdisp.c (fill_composite_glyph_string): Always set s->face, to
13246 avoid a crash (bug#9496).
13248 2011-11-09 Chong Yidong <cyd@gnu.org>
13250 * window.c (Fwindow_inside_edges, Fwindow_inside_pixel_edges)

13257 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
13259 Avoid some portability problems by eschewing 'extern inline' functions.
13260 The trivial performance wins aren't worth the portability hassles; see
13261 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
13263 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
13264 (window_box_width, window_box_left, window_box_left_offset)
13265 (window_box_right, window_box_right_offset): Undo previous change,
13266 by removing the "extern"s.
13267 * intervals.c (adjust_intervals_for_insertion)
13268 (adjust_intervals_for_deletion): Undo previous change,
13269 making these static again.
13270 (offset_intervals, temp_set_point_both, temp_set_point)
13271 (copy_intervals_to_string): No longer inline.
13272 * xdisp.c (window_text_bottom_y, window_box_width)

13303 (delete_all_subwindows): Rename to delete_all_child_windows.
13304 (Fdelete_other_windows_internal, Fset_window_configuration):
13305 Call delete_all_child_windows instead of delete_all_subwindows.

13309 2011-11-07 Paul Eggert <eggert@cs.ucla.edu>
13311 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
13312 This is also needed for porting to any host where GC_MARK_STACK is
13313 not GC_MAKE_GCPROS_NOOPS.
13314 (which_symbols): Use it.
13316 2011-11-07 Kenichi Handa <handa@m17n.org>
13318 * coding.c (coding_set_destination): Check coding->src_pos only
13319 when coding->src_object is a buffer (bug#9910).

13329 * xmenu.c (cleanup_widget_value_tree): New function.
13330 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
13331 calling free_menubar_widget_value_tree directly (Bug#9830).
13333 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
13335 Fix some portability problems with 'inline'.
13336 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
13337 (window_box_width, window_box_left, window_box_left_offset)
13338 (window_box_right, window_box_right_offset): Declare extern.
13339 Otherwise, these inline functions do not conform to C99 and
13340 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
13341 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
13342 * intervals.c (adjust_intervals_for_insertion)
13343 (adjust_intervals_for_deletion): Now extern, because otherwise the
13344 extern inline functions 'offset_intervals' couldn't refer to it.
13345 (static_offset_intervals): Remove.
13346 (offset_intervals): Rewrite using the old contents of
13347 static_offset_intervals. The old version didn't conform to C99
13348 because an extern inline function contained a reference to an
13349 identifier with static linkage.
13351 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
13353 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

13373 argument, since it makes no sense to pass a live window and for
13374 consistency with window-child.

13582 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
13584 (w32font_open_internal, compute_metrics):
13585 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
13586 instead of calling the "wide" APIs directly.
13588 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
13590 * w32.h (syms_of_w32font): Add prototype.
13592 2011-10-27 Juanma Barranquero <lekktu@gmail.com>

13596 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
13597 (Fmove_to_window_line): Doc fix.
13599 2011-10-27 Chong Yidong <cyd@gnu.org>
13601 * process.c (make_process): Set gnutls_state to NULL.
13603 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
13604 non-NULL, regardless of GNUTLS_INITSTAGE.
13605 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal

13632 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
13634 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
13636 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
13638 * keyboard.c (test_undefined): New function (bug#9751).
13639 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
13641 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
13643 * sysdep.c (init_sys_modes): Fix the check for the controlling
13644 terminal (Bug#6649).
13646 2011-10-20 Eli Zaretskii <eliz@gnu.org>
13648 * dispextern.h (struct bidi_it): New member next_en_type.
13650 * bidi.c (bidi_line_init): Initialize the next_en_type member.
13651 (bidi_resolve_explicit_1): When next_en_pos is valid for the
13652 current character, check also for next_en_type being WEAK_EN.
13653 (bidi_resolve_weak): Don't enter the expensive loop if the current
13654 position is before next_en_pos. Record the bidi type of the first
13655 non-ET, non-BN character we find, in addition to its position.
13656 (bidi_level_of_next_char): Invalidate next_en_type when
13657 next_en_pos is over-stepped.
13659 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
13661 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
13662 * editfns.c: Rewrite current-time-zone so that it invokes
13663 the equivalent of (format-time-string "%Z") to get the time zone name.
13664 This fixes a bug when the time zone name contains characters that
13665 need converting from the system time locale to Emacs internal format.
13666 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
13667 that patch fixed format-time-string to do the conversion, but
13668 I forgot to fix current-time-zone.
13669 (format_time_string): New function, containing most of
13670 what Fformat_time_string used to contain.
13671 (Fformat_time_string): Rewrite in terms of format_time_string.
13672 This doesn't change this function's behavior.
13673 (current-time-zone): Rewrite to use format_time_string.
13674 This fixes the bug reported by Michael Schierl in
13675 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
13676 Jason Rumney's 2007-06-07 change worked around this bug, but
13678 * systime.h (tzname, timezone): Remove no-longer-used declarations.
13680 2011-10-19 Eli Zaretskii <eliz@gnu.org>
13682 * xdisp.c (start_display): If the character at POS is displayed
13683 via a display vector, reset IT->current.dpvec_index to zero.
13684 (try_window_reusing_current_matrix): If a line ends in a display
13685 vector or the next line starts in a display vector, continue
13686 redrawing the window even though the character position of
13687 start_row was reached.
13690 2011-10-18 Chong Yidong <cyd@gnu.org>
13692 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
13693 with nobreak-char-display too.
13695 2011-10-18 Eli Zaretskii <eliz@gnu.org>
13697 Fix part 3 of bug#9771.
13698 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
13699 (bidi_resolve_neutral): Don't enter the expensive loop looking for
13700 non-neutral characters if the current character is a paragraph
13701 separator (a.k.a. Newline). This avoids running the same
13702 expensive loop twice, once when we consume the preceding newline
13703 and the other time when the line actually needs to be displayed.
13704 Avoid the loop when we see neutrals on the base embedding level
13705 following a character whose directionality is the same as the
13706 paragraph's. This avoids running the expensive loop when a line
13707 ends in a long sequence of neutrals, like control characters.
13708 Add assertion against STRONG_AL type. Slightly rearrange code
13709 that determines the type of a neutral given the first non-neutral
13711 (bidi_level_of_next_char): Set next_en_pos to zero when
13712 invalidating its info.
13714 2011-10-17 Eli Zaretskii <eliz@gnu.org>
13716 * xdisp.c (push_display_prop): Determine whether to record string
13717 or buffer position by IT->string, not by IT->method. Allow
13718 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
13719 (move_it_vertically_backward): Don't look for character position
13720 immediately after the newline when in a continuation line.
13723 2011-10-15 Martin Rudalics <rudalics@gmx.at>
13725 * window.c (coordinates_in_window): Rewrite and delabelize
13726 vertical border check. (Bug#5357) (Bug#9618)
13728 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
13730 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
13731 errors in XSetWindowBorder (bug#9310).
13733 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
13735 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
13736 avoid crash when xmalloc overrun checking is enabled.
13738 2011-10-13 Eli Zaretskii <eliz@gnu.org>
13740 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
13741 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
13742 cursor motion with <left> and <right> arrow keys.
13744 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
13745 some callers set that themselves.
13747 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13749 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
13750 display string and the previous row comes from the same string and
13751 is empty. (Bug#9739) (Bug#9738)
13753 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
13755 * doc.c (get_doc_string): Encode file name (bug#9735).
13757 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13759 * bidi.c (bidi_level_of_next_char):
13760 * xdisp.c (get_visually_first_element): Remove old incorrect
13761 comments regarding the Unicode Line Separator character.
13763 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
13765 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
13767 * alloc.c (Fgc_status): Do not access beyond zombies array
13768 boundary if nzombies > MAX_ZOMBIES.
13769 * alloc.c (dump_zombies): Add missing format specifier.
13771 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
13773 * xdisp.c (set_cursor_from_row): Simplify conditionals,
13774 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
13776 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
13777 Some packages use them to denote characters with modifiers.
13779 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
13781 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
13782 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
13783 matching a pp-number. Rename parameter var to var1.
13785 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
13787 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
13789 2011-10-08 Glenn Morris <rgm@gnu.org>
13791 * callint.c (Fcall_interactively): Give a more explicit error for the
13792 'c' case with a non-character input. (Bug#8479)
13794 2011-10-08 Eli Zaretskii <eliz@gnu.org>
13796 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
13798 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
13799 lines that are hscrolled on the left.
13801 * dispnew.c (buffer_posn_from_coords): Account for a possible
13802 presence of header-line. (Bug#4426)
13804 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
13806 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
13807 Don't advertise functionality which we discourage or doesn't work.
13809 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
13811 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
13812 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
13813 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
13814 this makes Emacs dump core during garbage collection on rare
13815 occasions. sizeof is obviously inferior to offsetof here, so
13816 stick with offsetof.
13817 (GC_POINTER_ALIGNMENT): New macro.
13818 (mark_memory): Omit 3rd (offset) arg; caller changed.
13819 Don't assume EMACS_INT alignment is the same as pointer alignment.
13821 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
13823 * keyboard.c (read_key_sequence_remapped): New var.
13824 (read_key_sequence): Compute remapping in the right buffer.
13825 (command_loop_1): Use read_key_sequence's remapping directly.
13827 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
13829 * dired.c (file_name_completion): Don't expand file name.
13830 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
13831 before checking file name handler.
13833 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
13834 they've been requested explicitly (bug#9591).
13836 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
13838 * keymap.c (Fsingle_key_description): Use make_specified_string
13839 instead of build_string to build string from push_key_description.
13842 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13844 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
13845 This fixes a Y2038 bug on 64-bit hosts.
13846 * buffer.c (reset_buffer):
13847 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
13848 (Fclear_buffer_auto_save_failure):
13849 Use 0, not -1, to represent an unset failure time, since time_t
13850 might not be signed.
13852 Remove dependency on glibc malloc internals.
13853 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13854 Move back here from lisp.h, but with their new implementations.
13855 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13856 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
13857 * charset.c (charset_table_init): New static var.
13858 (syms_of_charset): Use it instead of xmalloc. This removes a
13859 dependency on glibc malloc internals. See Eli Zaretskii's comment in
13860 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
13861 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13862 Move back to alloc.c.
13863 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13864 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
13866 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
13868 * nsterm.m (windowDidResize): Call x_set_window_size only when
13869 ns_in_resize is true. Otherwise set pixelwidth/height and
13870 call change_frame_size (Bug#9628).
13872 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13874 Port --enable-checking=all to Fedora 14 x86-64.
13875 * charset.c (syms_of_charset): Also account for glibc malloc's
13876 internal overhead when calculating the initial malloc maximum.
13878 Port --enable-checking=all to Fedora 14 x86.
13879 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13881 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
13882 (overrun_check_realloc, overrun_check_free):
13883 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
13884 That way, xmalloc returns a properly-aligned pointer even if
13885 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
13886 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
13887 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
13888 into account when calculating the initial malloc maximum.
13889 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13890 Move here from alloc.c, so that charset.c can use it too.
13891 Properly align; the old code wasn't right for common 32-bit hosts
13892 when configured with --enable-checking=all.
13893 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13894 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
13896 2011-09-29 Eli Zaretskii <eliz@gnu.org>
13898 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
13901 2011-09-28 Eli Zaretskii <eliz@gnu.org>
13903 * xdisp.c (compute_display_string_end): If there's no display
13904 string at CHARPOS, return -1.
13906 * bidi.c (bidi_fetch_char): When compute_display_string_end
13907 returns a negative value, treat the character as a normal
13908 character not covered by a display string. (Bug#9624)
13910 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
13912 * lread.c (Fread_from_string): Fix typo in docstring.
13914 2011-09-27 Eli Zaretskii <eliz@gnu.org>
13916 * xdisp.c (handle_invisible_prop): If invisible text ends on a
13917 newline, reseat the iterator instead of bidi-iterating there one
13918 character at a time. (Bug#9610)
13919 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
13920 TO_CHARPOS if the bidi iterator is at base embedding level.
13922 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
13924 * lread.c (readevalloop): Use correct code for NBSP.
13925 (read1): Likewise. (Bug#9608)
13927 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
13929 * dbusbind.c (Fdbus_register_signal): When service is not
13930 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
13932 2011-09-25 Glenn Morris <rgm@gnu.org>
13934 * buffer.c (truncate-lines): Doc fix.
13936 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
13938 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
13939 (Fset_window_next_buffers): Doc fix.
13941 2011-09-24 Glenn Morris <rgm@gnu.org>
13943 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
13945 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
13947 Fix minor problems found by static checking.
13948 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
13949 * indent.c (Fvertical_motion): Fix == vs = typo.
13951 2011-09-24 Eli Zaretskii <eliz@gnu.org>
13953 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
13954 Default value is now t. Doc fix.
13956 * indent.c (Fvertical_motion): Compute and apply the overshoot
13957 logic when moving up, not only when moving down. Fix the
13958 confusing name and values of the it_overshoot_expected variable;
13959 logic changes accordingly. (Bug#9254) (Bug#9549)
13961 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
13962 CHARPOS is covered by a display string which includes newlines.
13963 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
13964 is covered by a display string with embedded newlines.
13966 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
13968 * dbusbind.c (Fdbus_register_signal): Add match rule to
13969 Vdbus_registered_objects_table. (Bug#9581)
13970 (Fdbus_register_method, Vdbus_registered_objects_table):
13973 2011-09-24 Jim Meyering <meyering@redhat.com>
13975 do not ignore write error for any output size
13976 The previous change was incomplete.
13977 While it makes emacs --batch detect the vast majority of stdout
13978 write failures, errors were still ignored whenever the output size is
13979 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
13980 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
13981 && echo FAIL: ignored write error
13982 FAIL: ignored write error
13983 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
13984 && echo FAIL: ignored write error
13985 FAIL: ignored write error
13986 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
13988 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
13990 * emacs.c (Fkill_emacs): In noninteractive mode exit
13991 non-successfully if a write error occurred on stdout. (Bug#9574)
13993 2011-09-21 Eli Zaretskii <eliz@gnu.org>
13995 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
13998 * dispextern.h (struct it): Update the comment documenting what
14001 2011-09-20 Eli Zaretskii <eliz@gnu.org>
14003 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
14004 a display string, extend search for cursor position to end of row.
14005 (find_row_edges): If the row ends in a newline from a display
14006 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
14007 Handle the case of a display string with multiple newlines.
14008 (Fcurrent_bidi_paragraph_direction): Fix search for previous
14009 non-empty line. Fixes confusing cursor motion with arrow keys at
14010 the beginning of a line that starts with whitespace.
14012 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14014 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
14017 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
14019 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
14020 boolean (Bug#9154).
14022 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14024 * xdisp.c (display_line): Record maximum and minimum buffer
14025 positions even if no glyphs were produced (e.g., by a zero-width
14026 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
14027 buffer positions that will be removed from the glyph row because
14029 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
14030 column is beyond frame width: don't subtract 1 "pixel" when
14031 computing width of the stretch.
14032 (reseat_at_next_visible_line_start): Undo the change made on
14033 2011-09-17 that saved paragraph information and restored it after
14034 the call to `reseat'. (Bug#9545)
14036 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14038 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
14039 and turn window cursor on if cleared (Bug#9415).
14041 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
14043 * search.c (boyer_moore): Take unibyte characters from pattern
14044 literally. (Bug#9458)
14046 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14048 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
14050 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
14052 Fix minor problem found by static checking.
14053 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
14054 initialized, to pacify gcc -Wuninitialized.
14056 * fileio.c: Report proper errno when syscall falls.
14057 (Finsert_file_contents): Save and restore errno,
14058 so that report_file_error outputs the correct diagnostic.
14059 (Fwrite_region) [CLASH_DETECTION]: Likewise.
14061 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14063 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
14065 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14067 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
14068 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
14070 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14072 * xdisp.c (reseat_at_next_visible_line_start): Keep information
14073 about the current paragraph and restore it after the call to reseat.
14075 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
14076 (bidi_find_paragraph_start): Search back for paragraph beginning
14077 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
14078 (bidi_move_to_visually_next): Only trigger paragraph-related
14079 computations when the last character is a newline or at EOB, not
14080 just any NEUTRAL_B. (Bug#9470)
14082 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
14083 truncated lines if point is covered by a display string. (Bug#9524)
14085 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
14087 * xselect.c: Relax test for outgoing X longs (Bug#9498).
14088 (cons_to_x_long): New function.
14089 (lisp_data_to_selection_data): Use it. Correct the test for
14090 short-versus-long data; it was negated. Break out of vector
14091 loop, for efficiency, when a long datum is discovered.
14093 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
14095 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
14097 2011-09-16 Eli Zaretskii <eliz@gnu.org>
14099 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
14100 GCC PR/17406) by declaring this function with external scope.
14102 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14104 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
14105 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
14107 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
14109 * editfns.c (Fformat): Correctly handle text properties on "%%".

14115 * term.c (encode_terminal_code):
14116 * composite.c (composition_update_it, get_composition_id):
14117 * xdisp.c (get_next_display_element)
14118 (fill_composite_glyph_string): Add comments about special meaning
14119 of TAB characters in a composition.
14121 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14123 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
14124 This occurs when processing a multibyte format.
14125 Problem reported by Wolfgang Jenker.
14127 2011-09-15 Johan Bockgård <bojohan@gnu.org>
14129 * xdisp.c (try_cursor_movement): Only check for exact match if
14130 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
14132 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14134 Remove unused external symbols.
14135 * dispextern.h (calc_pixel_width_or_height): Remove decl.
14136 * xdisp.c (calc_pixel_width_or_height): Now static.
14137 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
14138 * indent.c (check_display_width):
14139 * w32term.c: Fix comment to match code.
14140 * xterm.c, xterm.h (x_catching_errors): Remove.
14142 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14144 * xselect.c: Use signed conversions more consistently (Bug#9498).
14145 (selection_data_to_lisp_data): Assume incoming selection data are
14146 signed integers, not unsigned. This is to be consistent with
14147 outgoing selection data, which was modified to use signed integers
14148 in as part of the fix to Bug#9196 in response to Jan D.'s comment
14149 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
14150 expects long, not unsigned long.
14152 2011-09-14 Eli Zaretskii <eliz@gnu.org>
14154 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
14155 computation of loop end. Reported by Johan Bockgård
14158 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
14160 * frame.c (Fother_visible_frames_p): Function deleted.
14162 2011-09-12 Eli Zaretskii <eliz@gnu.org>
14164 * indent.c (compute_motion): Process display vector front to back
14165 rather than the other way around. (Bug#2496)
14167 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
14169 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
14171 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
14173 * minibuf.c (Fread_from_minibuffer): Doc fix.
14175 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14177 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
14178 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
14180 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
14182 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
14183 value for non-existent files.
14185 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14187 * fileio.c (Finsert_file_contents): If the file cannot be opened,
14188 set its "size" to -1. This will set the modtime_size field of
14189 the corresponding buffer to -1, which is what
14190 verify-visited-file-modtime expects for files that do not exist.
14193 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
14195 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
14197 * lisp.h: ... from here. push_key_description is no longer
14198 defined in keyboard.c, so its declaration should not be in
14199 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
14200 logically belongs with push_key_description.
14202 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
14204 * buffer.h: Include <sys/types.h> instead of <time.h>.
14205 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
14206 Problem reported by Herbert J. Skuhra.
14208 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
14210 * xml.c (parse_region): Make the parsing work for
14211 non-comment-starting XML files again (bug#9144).
14213 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
14215 * image.c (gif_load): Fix calculation of bottom and right corner.
14218 2011-09-10 Eli Zaretskii <eliz@gnu.org>
14220 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
14221 redisplay in small windows.
14223 2011-09-09 Eli Zaretskii <eliz@gnu.org>
14225 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
14227 2011-09-08 Martin Rudalics <rudalics@gmx.at>
14229 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
14230 Operate on live windows only.
14232 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
14234 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
14236 2011-09-07 Eli Zaretskii <eliz@gnu.org>
14238 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
14239 only under bidi iteration.
14241 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
14243 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
14245 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14247 isnan: Fix porting problem to Solaris 10 with bundled gcc.
14248 Without this fix, the command to link temacs failed due to an
14249 undefined symbol __builtin_isnan. This is because
14250 /usr/include/iso/math_c99.h #defines isnan(x) to
14251 __builtin_isnan(x), but the bundled gcc, which identifies itself
14252 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
14254 * floatfns.c (isnan): #undef, and then #define to a clone of
14256 (Fisnan): Always define, since it's always available now.
14257 (syms_of_floatfns): Always define isnan at the Lisp level.
14259 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14261 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
14263 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14265 * fileio.c: Fix bugs with large file offsets (Bug#9428).
14266 The previous code assumed that file offsets (off_t values) fit in
14267 EMACS_INT variables, which is not true on typical 32-bit hosts.
14268 The code messed up by falsely reporting buffer overflow in cases
14269 such as (insert-file-contents "big" nil 1 2) into an empty buffer
14270 when "big" contains more than 2**29 bytes, even though this
14271 inserts just one byte and does not overflow the buffer.
14272 (Finsert_file_contents): Store file offsets as off_t
14273 values, not as EMACS_INT values. Check for overflow when
14274 converting between EMACS_INT and off_t. When checking for
14275 buffer overflow or for overlap, take the offsets into account.
14276 Don't use EMACS_INT for small values where int suffices.
14277 When checking for overlap, fix a typo: ZV was used where
14278 ZV_BYTE was intended.
14279 (Fwrite_region): Don't assume off_t fits into 'long'.
14280 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
14282 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
14284 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
14286 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14288 sprintf-related integer and memory overflow issues (Bug#9412).
14290 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
14291 (esprintf, exprintf, evxprintf): New functions.
14292 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
14293 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
14294 (modify_event_symbol): Do not assume that the length of
14295 name_alist_or_stem is safe to alloca and fits in int.
14296 (Fexecute_extended_command): Likewise for function name and binding.
14297 (Frecursion_depth): Wrap around reliably on integer overflow.
14298 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
14299 since some callers pass EMACS_INT values.
14300 (Fsingle_key_description): Don't crash if symbol name contains more
14301 than MAX_ALLOCA bytes.
14302 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
14303 (get_minibuffer): Arg is now EMACS_INT, not int.
14304 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
14305 (esprintf, exprintf, evxprintf): New decls.
14306 * window.h (command_loop_level, minibuf_level): Reflect API changes.
14308 * dbusbind.c (signature_cat): New function.
14309 (xd_signature, Fdbus_register_signal):
14310 Do not overrun buffer; instead, report string overflow.
14312 * dispnew.c (add_window_display_history): Don't overrun buffer.
14313 Truncate instead; this is OK since it's just a log.
14315 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
14316 even if the time zone offset is outlandishly large.
14317 Don't mishandle offset == INT_MIN.
14319 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
14320 when creating daemon; the previous buffer-overflow check was incorrect.
14322 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
14323 which has the guts of the old verror function.
14325 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
14326 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
14328 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
14329 (font_unparse_xlfd): Don't blindly alloca long strings.
14330 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
14331 fits in int, when using sprintf. Use single snprintf to count
14332 length of string rather than counting it via multiple sprintfs;
14333 that's simpler and more reliable.
14334 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
14335 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
14336 sprintf, in case result does not fit in int.
14338 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
14339 (fontset_from_font): Print it.
14341 * frame.c (tty_frame_count): Now printmax_t, not int.
14342 (make_terminal_frame, set_term_frame_name): Print it.
14343 (x_report_frame_params): In X, window IDs are unsigned long,
14344 not signed long, so print them as unsigned.
14345 (validate_x_resource_name): Check for implausibly long names,
14346 and don't assume name length fits in 'int'.
14347 (x_get_resource_string): Don't blindly alloca invocation name;
14348 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
14351 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
14352 (xg_check_special_colors, xg_set_geometry):
14353 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
14355 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
14356 Use esprintf, not sprintf, in case result does not fit in int.
14358 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14359 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
14360 it as a large positive number.
14361 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
14362 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14364 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
14365 in case result does not fit in int.
14367 * print.c (float_to_string): Detect width overflow more reliably.
14368 (print_object): Make sprintf buffer a bit bigger, to avoid potential
14369 buffer overrun. Don't assume list length fits in 'int'. Treat
14370 print length of 0 as 0, not as infinity; to be consistent with other
14371 uses of print length in this function. Don't overflow print length
14372 index. Don't assume hash table size fits in 'long', or that
14373 vectorlike size fits in 'unsigned long'.
14375 * process.c (make_process): Use printmax_t, not int, to format
14376 process-name gensyms.
14378 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
14380 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
14381 to avoid potential buffer overrun.
14383 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
14384 if X resource line is longer than 512 bytes.
14386 * xfns.c (x_window): Make sprintf buffer a bit bigger
14387 to avoid potential buffer overrun.
14389 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
14391 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
14393 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14395 Integer overflow fixes for scrolling, etc.
14396 Without these, Emacs silently mishandles large integers sometimes.
14397 For example, "C-u 4294967297 M-x recenter" was treated as if
14398 it were "C-u 1 M-x recenter" on a typical 64-bit host.
14400 * xdisp.c (try_window_id): Check Emacs fixnum range before
14401 converting to 'int'.
14403 * window.c (window_scroll_line_based, Frecenter):
14404 Check that an Emacs fixnum is in range before assigning it to 'int'.
14405 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
14406 values converted from Emacs fixnums.
14407 (Frecenter): Don't wrap around a line count if it is out of 'int'
14408 range; instead, treat it as an extreme value.
14409 (Fset_window_configuration, compare_window_configurations):
14410 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
14412 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
14413 that can exceed INT_MAX. Check that EMACS_INT value is in range
14414 before assigning it to the (possibly-narrower) index.
14415 (match_limit): Don't assume that a fixnum can fit in 'int'.
14417 * print.c (print_object): Use ptrdiff_t, not int, for index that can
14420 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
14421 (Fvertical_motion): Don't wrap around LINES values that don't fit
14422 in 'int'. Instead, treat them as extreme values. This is good
14423 enough for windows, which can't have more than INT_MAX lines anyway.
14425 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
14427 * Require libxml/parser.h to avoid compilation warning.
14429 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
14431 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
14432 since this reportedly can destroy thread storage.
14434 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
14436 * syntax.c (find_defun_start): Update all cache variables if
14437 exiting early (Bug#9401).
14439 2011-08-30 Eli Zaretskii <eliz@gnu.org>
14441 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
14443 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
14444 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
14445 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
14447 * term.c (tty_append_glyph): New function.
14448 (produce_stretch_glyph): Static function and its prototype deleted.
14450 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
14453 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
14455 * image.c (parse_image_spec): Check for nonnegative, not for positive,
14456 when checking :margin (Bug#9390).
14457 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
14458 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
14459 so that the name doesn't mislead. All uses changed.
14461 2011-08-28 Johan Bockgård <bojohan@gnu.org>
14463 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
14466 2011-08-27 Eli Zaretskii <eliz@gnu.org>
14468 * xdisp.c (move_it_to): Don't bail out early when reaching
14469 position beyond to_charpos, if we are scanning backwards.
14470 (move_it_vertically_backward): When DY == 0, make sure we get to
14471 the first character in the line after the newline.
14473 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
14475 * ccl.c: Improve and simplify overflow checking (Bug#9196).
14476 (ccl_driver): Do not generate an out-of-range pointer.
14477 (Fccl_execute_on_string): Remove unnecessary check for
14478 integer overflow, noted by Stefan Monnier in
14479 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
14480 Remove a FIXME that didn't need fixing.
14481 Simplify the newly-introduced buffer reallocation code.
14483 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
14485 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
14487 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
14489 Integer and memory overflow issues (Bug#9196).
14491 * doc.c (get_doc_string): Rework so that
14492 get_doc_string_buffer_size is the actual buffer size, rather than
14493 being 1 less than the actual buffer size; this makes xpalloc more
14496 * image.c (x_allocate_bitmap_record, cache_image):
14497 * xselect.c (Fx_register_dnd_atom):
14498 Simplify previous changes by using xpalloc.
14500 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
14501 since either will do and ptrdiff_t is convenient with xpalloc.
14503 * charset.c (charset_table_size)
14504 (struct charset_sort_data.priority): Now ptrdiff_t.
14505 (charset_compare): Don't overflow if priorities differ greatly.
14506 (Fsort_charsets): Don't assume list length fits in int.
14507 Check for size-calculation overflow when allocating sort data.
14508 (syms_of_charset): Allocate an initial charset table that is
14509 just under 64 KiB, to avoid problems with glibc malloc and mmap.
14511 * cmds.c (internal_self_insert): Check for size-calculation overflow.
14513 * composite.h (struct composition.glyph_len): Now int, not unsigned.
14514 The actual value is always <= INT_MAX, and leaving it unsigned made
14515 overflow checking harder.
14517 * dispextern.h (struct glyph_matrix.rows_allocated)
14518 (struct face_cache.size): Now ptrdiff_t, for convenience in use
14519 with xpalloc. The values are still always <= INT_MAX.
14521 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
14523 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
14524 (SAFE_NALLOCA): New macro.
14526 * region-cache.c (struct boundary.pos, find_cache_boundary)
14527 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
14528 (set_cache_region, invalidate_region_cache)
14529 (revalidate_region_cache, know_region_cache, region_cache_forward)
14530 (region_cache_backward, pp_cache):
14531 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
14532 so that ptrdiff_t * can be passed to xpalloc.
14533 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
14534 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
14535 (pp_cache): Don't assume cache_len fits in int.
14536 * region-cache.h: Adjust extern decls to match.
14538 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
14539 EMACS_INT, since either will do, for xpalloc.
14541 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
14542 (xnmalloc, xnrealloc, xpalloc): New functions.
14544 * bidi.c (bidi_shelve_header_size): New constant.
14545 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
14546 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
14548 * bidi.c (bidi_cache_shrink):
14549 * buffer.c (overlays_at, overlays_in, record_overlay_string)
14551 Don't update size of array until after memory allocation succeeds,
14552 because xmalloc/xrealloc may not return.
14553 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
14554 now that we have proper integer overflow checking.
14555 (record_overlay_string, overlay_strings): Catch overflows when
14556 calculating size of overlay_str_buf.
14558 * callproc.c (Fcall_process): Check for size overflow when
14559 calculating size of args2.
14560 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
14561 Normally we prefer signed values, but sticking with ptrdiff_t would
14562 require adding more-complicated checks.
14564 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
14565 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
14566 Redo buffer-overflow calculations to avoid integer overflow.
14567 Add a FIXME comment where memory seems to be over-allocated.
14569 * character.c (Fstring): Check for size-calculation overflow.
14571 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
14572 unnecessary integer overflow. Check for size overflow.
14573 (encode_coding_object): Don't update size until xmalloc succeeds.
14575 * composite.c (get_composition_id): Check for overflow in glyph
14576 length calculations.
14578 Integer and memory overflow fixes for display code.
14579 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
14580 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
14581 (scrolling_window): Check for overflow in size calculations.
14582 (line_draw_cost, realloc_glyph_pool, add_row_entry):
14583 Don't assume glyph table len fits in int.

14585 (row_table_size): Now ptrdiff_t, not int.
14586 (scrolling_window): Avoid overflow in size calculations.
14587 Don't update size until allocation succeeds.
14588 * fns.c (concat): Check for overflow in size calculations.
14589 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
14590 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
14591 (NEXT_ALMOST_PRIME_LIMIT): New constant.
14593 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
14594 (get_doc_string): Check for size calculation overflow.
14595 Don't update size until allocation succeeds.
14596 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
14597 EMACS_INT, where ptrdiff_t will do.
14598 (Fsubstitute_command_keys): Check for string overflow.
14600 * editfns.c (set_time_zone_rule): Don't assume environment length
14602 (message_length): Now ptrdiff_t, not int.
14603 (Fmessage_box): Don't update size until allocation succeeds.
14604 Don't assume message length fits in int.
14605 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
14607 * emacs.c (main): Do not reallocate argv, since there is a null at
14608 the end that can be overwritten, and this way there's no need to
14609 worry about size-calculation overflow.
14610 (sort_args): Check for size-calculation overflow.
14612 * eval.c (init_eval_once, grow_specpdl): Don't update size until
14614 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
14616 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
14617 (x_set_scroll_bar_width, x_figure_window_size):
14618 Check for integer overflow.
14619 (x_set_alpha): Do not assume XINT fits in int.
14621 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
14622 This is for the members text_lines, text_cols, total_lines, total_cols,
14623 where the system imposes an 'int' limit.
14625 * fringe.c (Fdefine_fringe_bitmap):
14626 Don't update size until alloc works.
14628 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
14629 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
14631 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
14632 Check for size-calculation overflow.
14633 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
14634 do, as we prefer signed integers.
14635 (id_to_widget.max_size, id_to_widget.used)
14636 (xg_store_widget_in_map, xg_remove_widget_from_map)
14637 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
14638 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
14639 Use and return ptrdiff_t, not int.
14640 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
14641 * gtkutil.h: Change prototypes to match the above.
14643 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
14644 are duplicate now that they've been promoted to lisp.h.
14645 (x_allocate_bitmap_record, x_alloc_image_color)
14646 (make_image_cache, cache_image, xpm_load):
14647 Don't update size until alloc is done.
14648 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
14650 Check for size calculation overflow.
14651 (ct_colors_allocated_max): New constant.
14652 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
14655 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
14656 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
14657 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
14658 Use ptrdiff_t, not int, to count maps.
14659 (read_char_minibuf_menu_prompt): Check for overflow in size
14660 calculations. Don't update size until allocation succeeds.
14661 Redo calculations to avoid overflow.
14662 * keyboard.h: Change prototypes to match the above.
14664 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
14666 (current_minor_maps): Check for size calculation overflow.
14667 * keymap.h: Change prototypes to match the above.
14669 * lread.c (read1, init_obarray): Don't update size until alloc done.
14671 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.

14690 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
14691 for command line length. Do not attempt to address one before the
14692 beginning of an array, as that's not portable.
14694 * term.c (max_frame_lines): Remove; unused.
14695 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
14697 (encode_terminal_code, calculate_costs): Check for size
14698 calculation overflow.
14699 (encode_terminal_code): Use ptrdiff_t, not int, to record glyph

14716 Use ptrdiff_t, not int, for sizes.
14717 (store_mode_line_noprop_char): Don't update size until alloc done.
14719 * xfaces.c (lface_id_to_name_size, Finternal_make_lisp_face):
14720 Use ptrdiff_t, not int, for sizes.
14721 (Finternal_make_lisp_face, cache_face):
14722 Check for size calculation overflow.
14723 (cache_face): Treat size calculation overflows as if they were
14724 memory exhaustion (the usual treatment), rather than aborting.
14726 * xfns.c (x_encode_text, x_set_name_internal)
14727 (Fx_change_window_property): Use ptrdiff_t, not int, to count
14728 sizes, since they can exceed INT_MAX in size. Check for size
14729 calculation overflow.
14731 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
14732 (xg_select): Check for size calculation overflow.
14733 Don't update size until alloc done.
14735 * xrdb.c (get_environ_db): Don't assume path length fits in int,
14736 as sprintf is limited to int lengths.
14738 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
14739 (X_LONG_MIN): New macros.
14740 Use them to make the following changes clearer.
14741 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
14742 This change doesn't affect the value now, but it may help remind
14743 future maintainers not to raise the value too much later.
14744 (SELECTION_QUANTUM): Remove, replacing with ...
14745 (selection_quantum): ... new function, which avoids overflow.
14747 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
14748 assumption that selection length fits in 'int'.
14749 (x_reply_selection_request, x_handle_selection_request)
14750 (x_get_window_property, receive_incremental_selection)
14751 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
14752 (lisp_data_to_selection_data, clean_local_selection_data):
14753 Use ptrdiff_t, not int, to record length of selection.
14754 (x_reply_selection_request, x_get_window_property)
14755 (receive_incremental_selection, x_property_data_to_lisp):
14756 Redo calculations to avoid overflow.
14757 (x_reply_selection_request): When sending hint, ceiling it at
14758 X_LONG_MAX rather than relying on wraparound overflow to send
14760 (x_get_window_property, receive_incremental_selection)
14761 (lisp_data_to_selection_data, x_property_data_to_lisp):
14762 Check for size-calculation overflow.
14763 (x_get_window_property, receive_incremental_selection)

14765 Don't store size until memory allocation succeeds.
14766 (x_get_window_property): Plug memory leak on memory exhaustion.
14767 Don't double-block input; malloc is safe here. Don't assume 2**34
14768 - 4 fits in unsigned long. Add an xassert to check
14769 XGetWindowProperty overflow. Be more careful about overflow
14770 calculations, and distinguish size from memory overflow better.
14771 (receive_incremental_selection): When tracing, don't assume
14772 unsigned int is less than INT_MAX.
14773 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
14774 harmful) conversions of unsigned short to int.
14775 (lisp_data_to_selection_data): Don't assume that integers
14776 in the range -65535 through -1 fit in an X unsigned short.
14777 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
14778 result parameters unless successful. Rely on cons_to_unsigned
14779 to report problems with elements; the old code wasn't right anyway.
14780 (x_check_property_data): Check for int overflow; we cannot use
14781 a wider type due to X limits.
14782 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
14784 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
14786 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
14787 (x_term_init): Check for size calculation overflow.
14788 (x_color_cells): Don't store size until memory allocation succeeds.
14789 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
14790 Don't assume alloca size is less than MAX_ALLOCA.
14791 (x_term_init): Don't assume length fits in int (sprintf is limited
14794 Use ptrdiff_t for composition IDs.
14795 * character.c (lisp_string_width):
14796 * composite.c (composition_table_size, n_compositions)
14797 (get_composition_id, composition_gstring_from_id):
14798 * dispextern.h (struct glyph_string.cmp_id, struct composition_it.id):
14799 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING):
14800 * window.c (Frecenter):
14801 Use ptrdiff_t, not int, for composition IDs.
14802 * composite.c (get_composition_id): Check for integer overflow.
14803 * composite.h: Adjust prototypes to match the above changes.

14813 * image.c (xpm_get_color_table_h):
14814 * lisp.h (hash_lookup, hash_put):
14815 * minibuf.c (Ftest_completion):
14816 Use ptrdiff_t for hash table indexes, not int (which is too
14817 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
14818 32-bit --with-wide-int hosts).
14820 * charset.c (Fdefine_charset_internal): Check for integer overflow.
14821 Add a FIXME comment about memory leaks.
14822 (syms_of_charset): Don't assume xmalloc returns.
14824 Don't assume that stated character widths fit in int.
14825 * character.c (Fchar_width, c_string_width, lisp_string_width):
14826 * character.h (CHAR_WIDTH):
14827 * indent.c (MULTIBYTE_BYTES_WIDTH):
14828 Use sanitize_char_width to avoid undefined and/or bad behavior
14829 with outlandish widths.
14830 * character.h (sanitize_tab_width): Rename from sanitize_width,
14831 now that we have two such functions. All uses changed.
14832 (sanitize_char_width): New inline function.
14834 Don't assume that tab-width fits in int.
14835 * character.h (sanitize_width): New inline function.
14836 (SANE_TAB_WIDTH): New macro.
14837 (ASCII_CHAR_WIDTH): Use it.
14838 * indent.c (sane_tab_width): Remove. All uses replaced by
14839 SANE_TAB_WIDTH (current_buffer).
14840 * xdisp.c (init_iterator): Use SANE_TAB_WIDTH.
14842 * fileio.c: Integer overflow issues with file modes.
14843 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
14845 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
14846 Remove unreachable code.
14847 (read_hex, load_charset_map_from_file): Check for integer overflow.
14849 * xterm.c: Don't go over XClientMessageEvent limit.
14850 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
14851 (x_send_scroll_bar_event): Likewise. Check that the size does not
14852 exceed limits imposed by XClientMessageEvent, as well as the usual
14853 ptrdiff_t and size_t limits.
14855 * keyboard.c: Overflow, signedness and related fixes.
14856 (make_lispy_movement): Use same integer type in forward decl
14857 that is used in the definition.
14858 (read_key_sequence, keyremap_step):
14859 Change bufsize argument back to int, undoing my 2011-03-30 change.
14860 We prefer signed types, and int is wide enough here.
14861 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
14862 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
14863 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
14864 length, not size_t. Use ptrdiff_t for index, not int.
14865 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
14866 possibility of integer overflow.
14868 Overflow, signedness and related fixes for images.
14870 * dispextern.h (struct it.stack[0].u.image.image_id)
14871 (struct_it.image_id, struct image.id, struct image_cache.size)
14872 (struct image_cache.used, struct image_cache.ref_count):

14878 * xdisp.c (calc_pixel_width_or_height):
14879 * xfns.c (image_cache_refcount):
14880 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
14881 on typical 64-bit hosts.

14887 when the callers expect that.
14888 (image_ascent): Redo ascent calculation to avoid int overflow.
14889 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
14890 (lookup_image): Remove unnecessary tests.
14891 (xbm_image_p): Locals are now of int, not EMACS_INT,
14892 since parse_image_check makes sure they fit into int.
14893 (png_load, gif_load, svg_load_image):
14894 Prefer int to unsigned where either will do.
14895 (tiff_handler): New function, combining the cores of the
14896 old tiff_error_handler and tiff_warning_handler.
14897 This function is rewritten to use vsnprintf and thereby avoid
14898 stack buffer overflows. It uses only the features of vsnprintf
14899 that are common to both POSIX and native Microsoft.
14900 (tiff_error_handler, tiff_warning_handler): Use it.
14901 (tiff_load, gif_load, imagemagick_load_image):
14902 Don't assume :index value fits in 'int'.
14903 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
14904 (imagemagick_load_image): Check that crop parameters fit into
14905 the integer types that MagickCropImage accepts. Don't assume
14906 Vimagemagick_render_type has a nonnegative value. Don't assume
14907 size_t fits in 'long'.
14908 (gs_load): Use printmax_t to print the widest integers possible.
14909 Check for integer overflow when computing image height and width.
14911 2011-08-26 Eli Zaretskii <eliz@gnu.org>
14913 * xdisp.c (redisplay_window): Don't force window start if point
14914 will be invisible in the resulting window. (Bug#9324)
14916 2011-08-25 Eli Zaretskii <eliz@gnu.org>
14918 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
14919 the display spec is of the form `(space ...)'.
14920 (handle_display_spec): Return the value returned by
14921 handle_single_display_spec, not just 1 or zero.
14922 (handle_single_display_spec): If the display spec is of the form
14923 `(space ...)', and specifies display in the text area, return 2
14925 (try_cursor_movement): Check for the need to scroll more
14926 accurately, and prefer exact match for point under bidi.
14927 Don't advance `row' beyond the last row of the window.
14929 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
14930 into disp_prop; all users changed.
14932 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
14933 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
14934 for the text covered by the display property.
14936 2011-08-25 Chong Yidong <cyd@stupidchicken.com>
14938 * buffer.c (Fbury_buffer_internal): Rename from Funrecord_buffer.

14942 2011-08-24 Eli Zaretskii <eliz@gnu.org>
14944 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
14945 buffers, return left-to-right.
14946 (set_cursor_from_row): Consider candidate row a win if its glyph
14947 represents a newline and point is on that newline. Fixes cursor
14948 positioning on the newline at EOL of R2L text within L2R
14949 paragraph, and vice versa.
14950 (try_cursor_movement): Check continued rows, in addition to
14951 continuation rows. Fixes unwarranted scroll when point enters a
14952 continued line of R2L text within an L2R paragraph, or vice versa.
14953 (cursor_row_p): Consider the case of point being equal to
14954 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
14955 from the end of a short line to the beginning of a continued line
14956 of R2L text within L2R paragraph.
14957 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
14958 composed characters.
14960 * bidi.c (bidi_check_type): Use xassert.

14969 2011-08-23 Chong Yidong <cyd@stupidchicken.com>
14971 * nsfont.m (ns_otf_to_script): Fix typo.
14973 2011-08-22 Kenichi Handa <handa@m17n.org>
14975 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
14976 extra slot even if the purpose is char-code-property-table.
14978 2011-08-23 Eli Zaretskii <eliz@gnu.org>
14980 * xdisp.c (redisplay_window): When computing centering_position,
14981 account for the height of the header line. (Bug#8874)
14983 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
14984 instead of CHAR_TO_BYTE. Fixes a crash when a completion
14985 candidate is selected by the mouse, and that candidate has a
14986 composed character under the mouse.
14988 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
14989 coordinates reported by pos-visible-in-window-p for a composed
14990 character in column zero.
14992 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
14994 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
14996 2011-08-22 Eli Zaretskii <eliz@gnu.org>
14998 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
14999 consider it a hit if to_charpos is anywhere in the range of the
15000 composed buffer positions.
15002 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
15004 * image.c (gif_load): Don't assume that each subimage has the same
15005 dimensions as the base image. Handle disposal method that is
15006 "undefined" by the gif spec (Bug#9335).
15008 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
15010 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
15011 (Fcondition_case): Document `debug' symbol in error handler.
15013 2011-08-19 Eli Zaretskii <eliz@gnu.org>
15015 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
15016 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
15017 from an Org mode buffer to a Speedbar frame.
15019 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
15020 a composition, take its buffer position from IT->cmp_it.charpos.
15021 Fixes cursor positioning at the beginning of a line that begins
15022 with a composed character.
15024 2011-08-18 Eli Zaretskii <eliz@gnu.org>
15026 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
15027 character bidirectional type, use STRONG_L instead. Fixes crashes
15028 in a buffer produced by `describe-categories'.
15030 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
15031 members before the level stack, so they would be saved and
15032 restored when copying iterator state. Fixes incorrect reordering
15033 around TABs covered by display properties.
15035 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
15037 * process.c (Fnetwork_interface_list): Correctly determine buffer size.
15039 2011-08-17 Chong Yidong <cyd@stupidchicken.com>
15041 * eval.c (internal_condition_case, internal_condition_case_1)
15042 (internal_condition_case_2, internal_condition_case_n):
15043 Remove unnecessary aborts (Bug#9081).
15045 2011-08-17 Eli Zaretskii <eliz@gnu.org>
15047 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
15048 has no `load' handler, try opening the file locally. (Bug#9311)
15050 2011-08-16 Ken Brown <kbrown@cornell.edu>
15052 * gmalloc.c: Expand comment.
15054 2011-08-16 Eli Zaretskii <eliz@gnu.org>
15056 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
15057 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
15059 2011-08-16 Ken Brown <kbrown@cornell.edu>
15061 Fix memory allocation problems in Cygwin build (Bug#9273).
15063 * unexcw.c ( __malloc_initialized): Declare external variable.
15064 (fixup_executable): Force the dumped emacs to reinitialize malloc.
15066 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
15068 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
15070 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
15071 in the static heap.
15072 [CYGWIN] (special_realloc): New function.
15073 (_realloc_internal_nolock) [CYGWIN]: Use the new function on

15087 * dispextern.h: Fix a typo in the comment to bidi_type_t.
15089 * chartab.c: Improve commentary for the uniprop_table API.
15091 * bidi.c (bidi_paragraph_init): Support zero value of
15092 bidi_ignore_explicit_marks_for_paragraph_level.
15093 (bidi_initialize): Use uniprop_table instead of including
15094 biditype.h and bidimirror.h.
15096 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
15097 coordinates of the iterator when restoring from ppos_it.
15100 2011-08-14 Kenichi Handa <handa@m17n.org>
15102 * process.c (create_process): Call setup_process_coding_systems
15103 after the pid of the process is set to -1 (Bug#8162).
15105 2011-08-14 Eli Zaretskii <eliz@gnu.org>
15107 * xdisp.c (move_it_in_display_line_to): Don't invoke
15108 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
15109 ppos_it. Fixes vertical cursor motion when line beginning is
15110 covered by an image. (Bug#9296)
15112 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
15114 * nsterm.h (ns_run_ascript): Declare.
15115 (NSAPP_DATA2_RUNASSCRIPT): Define.
15117 * nsfns.m (as_script, as_result, as_status): New static variables.
15118 (ns_run_ascript): New function.
15119 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
15120 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
15121 the event loop. Get status from as_status (Bug#7276).
15123 * nsterm.m (sendEvent): If event is NSApplicationDefined and
15124 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
15125 the event loop (Bug#7276).
15127 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
15129 * gnutls.c (QCgnutls_bootprop_priority)
15130 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
15131 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
15132 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)

15134 (QCgnutls_bootprop_verify_hostname_error)
15135 (QCgnutls_bootprop_callbacks_verify): Rename from
15136 Qgnutls_bootprop_..., all uses changed.
15138 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
15141 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
15143 * xfaces.c (Qframe_set_background_mode): Now static.
15144 * dispextern.h (Qframe_set_background_mode): Remove decl.
15146 * process.c (Fnetwork_interface_info): Declare local only if needed.
15148 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
15150 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
15151 (Fnetwork_interface_list): Allocate in increments of bytes instead
15152 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
15153 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
15155 (struct ifflag_def): notrailers is smart on OSX.
15156 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
15157 Get hardware address with getifaddrs if available.
15159 2011-08-12 Eli Zaretskii <eliz@gnu.org>
15161 * xdisp.c (iterate_out_of_display_property): xassert that
15162 IT->position is set to within IT->object's boundaries. Break from
15163 the loop as soon as EOB is reached; avoids infloops in redisplay
15164 when IT->position is set up wrongly due to some bug.
15165 Set IT->current to match the bidi iterator unconditionally.
15166 (push_display_prop): Allow GET_FROM_STRING as IT->method on
15167 entry. Force push_it to save on the stack the current
15168 buffer/string position, to be restored by pop_it. Fix flags in
15169 the iterator structure wrt the object coming from a display
15170 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
15171 properties. (Bug#9284)
15173 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
15175 * fontset.c (fontset_get_font_group): Add proper type checks.
15178 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>

15188 no-display-properties-and-no-overlays under bidi display.
15189 Set disp_pos in the bidi iterator to avoid searches for display
15190 properties and overlays.
15192 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
15194 * editfns.c (Fset_time_zone_rule): Document relationship with the

15198 the font entity extracted from the cache (Bug#8109).
15200 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
15202 * composite.c (autocmp_chars): Don't reset point. That is done by
15203 restore_point_unwind (Bug#5984).
15205 2011-08-07 Juri Linkov <juri@jurta.org>
15207 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
15208 to show the arg `TIME' instead of `TIMEVAL'.
15210 2011-08-06 Eli Zaretskii <eliz@gnu.org>
15212 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
15213 display property strides EOL and includes a newline, as in
15214 longlines-mode. (Bug#9254)
15215 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
15216 word-wrap under bidirectional display. (Bug#9224)
15218 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
15219 is non-zero, even if the data buffer is NULL. Fixes a crash in
15220 vertical-motion with longlines-mode. (Bug#9254)
15222 2011-08-05 Eli Zaretskii <eliz@gnu.org>
15224 * bidi.c <bidi_cache_total_alloc>: Now static.
15225 (bidi_initialize): Initialize bidi_cache_total_alloc.
15227 * xdisp.c (display_line): Release buffer allocated for shelved bidi
15230 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
15231 amount allocated this far in `bidi_cache_total_alloc'.
15232 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
15233 non-zero, only free the data buffer without restoring the cache
15234 contents. All callers changed.
15236 * dispextern.h (bidi_unshelve_cache): Update prototype.
15238 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
15239 (move_it_in_display_line, move_it_to)
15240 (move_it_vertically_backward, move_it_by_lines): Replace the call
15241 to xfree to an equivalent call to bidi_unshelve_cache.
15242 (move_it_in_display_line_to): Fix logic of returning
15243 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
15245 2011-08-05 Eli Zaretskii <eliz@gnu.org>
15247 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
15248 came from a string character with a `cursor' property. (Bug#9229)
15250 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
15252 * Makefile.in (LIB_PTHREAD): New variable.
15253 (LIBES): Add LIB_PTHREAD (Bug#9216).
15255 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
15256 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
15258 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
15260 * regex.c (re_iswctype): Remove some redundant boolean conversions.
15262 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
15264 * xterm.c (x_find_topmost_parent): New function.
15265 (x_set_frame_alpha): Find topmost parent window with
15266 x_find_topmost_parent and set the property there also (bug#9181).
15267 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
15269 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
15271 * callproc.c (Fcall_process): Avoid vfork clobbering
15272 the local vars buffer, coding_systems, current_dir.
15274 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
15276 * keymap.c (Fmake_composed_keymap): Move to subr.el.
15278 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
15280 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
15281 so that it is not optimized away.
15283 * xdisp.c (compute_display_string_pos): Remove unused local.
15285 2011-08-02 Eli Zaretskii <eliz@gnu.org>
15287 Fix slow cursor motion and scrolling in large buffers with
15288 selective display, like Org Mode buffers. (Bug#9218)
15290 * dispextern.h (struct bidi_it): New member disp_prop_p.
15292 * xdisp.c: Remove one-slot cache of display string positions.
15293 (compute_display_string_pos): Accept an additional argument
15294 DISP_PROP_P; callers changed. Scan at most 5K characters forward
15295 for a display string or property. If found, set DISP_PROP_P
15298 * bidi.c (bidi_fetch_char): Accept an additional argument
15299 DISP_PROP_P, and pass it to compute_display_string_pos.
15300 Only handle text covered by a display string if DISP_PROP_P is returned
15301 non-zero. All callers of bidi_fetch_char changed.
15303 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
15305 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
15307 2010-12-03 Don March <don@ohspite.net>
15309 * keymap.c (Fdefine_key): Fix non-prefix key error message when
15310 last character M-[char] is translated to ESC [char] (bug#7541).
15312 2011-08-02 Kenichi Handa <handa@m17n.org>
15314 * lisp.h (uniprop_table): Extern it.
15316 * chartab.c (uniprop_table): Make it non-static.
15318 2011-08-01 Eli Zaretskii <eliz@gnu.org>
15320 * xdisp.c (forward_to_next_line_start): Accept additional argument
15321 BIDI_IT_PREV, and store into it the state of the bidi iterator had
15323 (reseat_at_next_visible_line_start): Use the bidi iterator state
15324 returned by forward_to_next_line_start to restore the state of
15325 it->bidi_it after backing up to previous newline. (Bug#9212)
15327 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
15329 * regex.c (re_comp): Protoize.
15330 (re_exec): Fix return type.
15331 (regexec): Fix type of `ret'. (Bug#9203)
15333 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15335 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
15336 This is needed if max-image-size is a floating-point number.
15338 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15340 * print.c (print_object): Print empty symbol as ##.
15342 * lread.c (read1): Read ## as empty symbol.
15344 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
15346 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
15347 setting frame foreground color (Bug#9175).
15348 (x_set_background_color): Likewise.
15350 * nsmenu.m (-setText): Size tooltip dimensions precisely to
15351 contents (Bug#9176).
15352 (EmacsTooltip -init): Remove bezels and add shadows to
15355 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
15356 or scroll bar (Bug#8470).
15358 * nsfont.m (nsfont_open): Remove assignment to voffset and
15359 unnecessary vars hshink, expand, hd, full_height, min_height.
15360 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
15362 * nsterm.h (nsfont_info): Remove voffset field.
15364 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
15366 Implement strike-through and overline on NextStep (Bug#8863).
15368 * nsfont.m (nsfont_open): Use underline position provided by font,
15369 instead of hard-coded value of 2.
15370 (nsfont_draw): Call ns_draw_text_decoration instead.
15372 * nsterm.h: Add declaration for ns_draw_text_decoration.
15374 * nsterm.m (ns_draw_text_decoration): New function for drawing
15375 underline, overline, and strike-through.
15376 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
15377 ns_draw_text_decoration. Change treatment of cursor drawing to
15378 accommodate underlining, etc.
15380 2011-07-28 Eli Zaretskii <eliz@gnu.org>
15382 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
15385 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15387 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
15388 Without this fix, if a signal arrives just after memory fills up,
15389 'malloc' might be invoked reentrantly.
15391 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
15392 In other words, assume that every image size is allowed, on non-X
15393 hosts. This assumption is probably wrong, but it lets Emacs compile.
15395 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15397 * regex.c (re_iswctype): Convert return values to boolean.
15399 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
15401 * xdisp.c (compute_display_string_pos): Don't use cached display
15402 string position if the buffer had its restriction changed.
15405 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15407 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
15409 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15411 Integer signedness and overflow and related fixes. (Bug#9079)
15413 * bidi.c: Integer size and overflow fixes.
15414 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
15415 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
15416 (bidi_cache_find_level_change, bidi_cache_ensure_space)
15417 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
15418 (bidi_find_other_level_edge):
15419 Use ptrdiff_t instead of EMACS_INT where either will do.
15420 This works better on 32-bit hosts configured --with-wide-int.
15421 (bidi_cache_ensure_space): Check for size-calculation overflow.
15422 Use % rather than repeated addition, for better worst-case speed.
15423 Don't set bidi_cache_size until after xrealloc returns, because it
15425 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
15426 (bidi_cache_ensure_space): Also check that the bidi cache size
15427 does not exceed that of the largest Lisp string or buffer. See Eli
15428 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
15430 * alloc.c (__malloc_size_t): Remove.
15431 All uses replaced by size_t. See Andreas Schwab's note
15432 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
15434 * image.c: Improve checking for integer overflow.
15435 (check_image_size): Assume that f is nonnull, since
15436 it is always nonnull in practice. This is one less thing to
15437 worry about when checking for integer overflow later.
15438 (x_check_image_size): New function, which checks for integer
15439 overflow issues inside X.
15440 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
15441 This removes the need for a memory_full check.
15442 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
15443 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
15444 (xbm_read_bitmap_data): Change locals back to 'int', since
15445 their values must fit in 'int'.
15446 (xpm_load_image, png_load, tiff_load):
15447 Invoke x_create_x_image_and_pixmap earlier,
15448 to avoid much needless work if the image is too large.
15449 (tiff_load): Treat overly large images as if
15450 x_create_x_image_and_pixmap failed, not as malloc failures.
15451 (gs_load): Use x_check_image_size.
15453 * gtkutil.c: Omit integer casts.
15454 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
15455 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
15457 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
15459 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
15460 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
15461 would wrongly return t on a 64-bit host.
15463 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
15464 The plain *_OVERFLOW macros run afoul of GCC bug 49705
15465 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
15466 and therefore cause GCC to emit a bogus diagnostic in some cases.
15468 * image.c: Integer signedness and overflow and related fixes.
15469 This is not an exhaustive set of fixes, but it's time to
15470 record what I've got.
15471 (lookup_pixel_color, check_image_size): Remove redundant decls.
15472 (check_image_size): Don't assume that arbitrary EMACS_INT values
15473 fit in 'int', or that arbitrary 'double' values fit in 'int'.
15474 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
15475 (tiff_load, imagemagick_load_image):
15476 Check for overflow in size calculations.
15477 (x_create_x_image_and_pixmap): Remove unnecessary test for
15478 xmalloc returning NULL; that can't happen.
15479 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
15480 (xpm_color_bucket): Use better integer hashing function.
15481 (xpm_cache_color): Don't possibly over-allocate memory.
15482 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
15483 (gif_memory_source):
15484 Use ptrdiff_t, not int or size_t, to record sizes.
15485 (png_load): Don't assume values greater than 2**31 fit in 'int'.
15486 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
15487 either works, as we prefer signed integers.
15488 (tiff_read_from_memory, tiff_write_from_memory):
15489 Return tsize_t, not size_t, since that's what the TIFF API wants.
15490 (tiff_read_from_memory): Don't fail simply because the read would
15491 go past EOF; instead, return a short read.
15492 (tiff_load): Omit no-longer-needed casts.
15493 (Fimagemagick_types): Don't assume size fits into 'int'.
15495 Improve hashing quality when configured --with-wide-int.
15496 * fns.c (hash_string): New function, taken from sxhash_string.
15497 Do not discard information about ASCII character case; this
15498 discarding is no longer needed.
15499 (sxhash-string): Use it. Change sig to match it. Caller changed.
15500 * lisp.h: Declare it.
15501 * lread.c (hash_string): Remove, since we now use fns.c's version.
15502 The fns.c version returns a wider integer if --with-wide-int is
15503 specified, so this should help the quality of the hashing a bit.
15505 * emacs.c: Integer overflow minor fix.
15506 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
15507 Define only if GNU_LINUX.
15508 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
15510 * dispnew.c: Integer signedness and overflow fixes.
15511 Remove unnecessary forward decls, that were a maintenance hassle.
15512 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
15514 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
15515 (scrolling_window): Use ptrdiff_t, not int, for byte count.
15516 (prepare_desired_row, line_draw_cost):
15517 Use int, not unsigned, where either works.
15518 (save_current_matrix, restore_current_matrix):
15519 Use ptrdiff_t, not size_t, where either works.
15520 (init_display): Check for overflow more accurately, and without
15521 relying on undefined behavior.
15523 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
15524 Remove, replacing with the new symbols in lisp.h. All uses changed.
15525 * fileio.c (make_temp_name):
15526 * filelock.c (lock_file_1, lock_file):
15527 * xdisp.c (message_dolog):
15528 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
15529 Use pMd etc. instead.
15530 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
15531 replacing the pWIDE etc. symbols removed from editfns.c.
15533 * keyboard.h (num_input_events): Now uintmax_t.
15534 This is (very slightly) less likely to mess up due to wraparound.
15537 * buffer.c: Integer signedness fixes.
15538 (alloc_buffer_text, enlarge_buffer_text):
15539 Use ptrdiff_t rather than size_t when either will do, as we prefer
15542 * alloc.c: Integer signedness and overflow fixes.
15543 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
15544 (__malloc_size_t): Default to size_t, not to int.
15545 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
15546 (Fgarbage_collect, mark_object_loop_halt, mark_object):
15547 Prefer ptrdiff_t to size_t when either would do, as we prefer
15549 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
15550 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
15551 Now const. Initialize with values that are in range even if char
15553 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
15554 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
15555 These functions do the right thing with sizes > 2**32.
15556 (check_depth): Now ptrdiff_t, not int.
15557 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
15558 Adjust to new way of storing sizes. Check for size overflow bugs
15560 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
15561 slightly wrong anyway, as it missed one instance of
15562 XMALLOC_OVERRUN_CHECK_OVERHEAD.
15563 (refill_memory_reserve): Omit needless cast to size_t.
15564 (mark_object_loop_halt): Mark as externally visible.
15566 * xselect.c: Integer signedness and overflow fixes.
15567 (Fx_register_dnd_atom, x_handle_dnd_message):
15568 Use ptrdiff_t, not size_t, since we prefer signed.
15569 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
15570 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
15571 x_dnd_atoms_size and x_dnd_atoms_length.
15573 * doprnt.c: Prefer signed to unsigned when either works.
15575 * doprnt.c (doprnt):
15577 * xdisp.c (vmessage):
15578 Use ptrdiff_t, not size_t, when using or implementing doprnt,
15579 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
15580 prefer signed arithmetic to avoid comparison confusion.
15581 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
15582 but is a bit tricky.
15584 Assume freestanding C89 headers, string.h, stdlib.h.
15585 * data.c, doprnt.c, floatfns.c, print.c:
15586 Include float.h unconditionally.
15587 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
15588 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
15589 * regex.c: Likewise for stddef.h, string.h.
15590 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
15591 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
15592 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
15593 (STDC_HEADERS): Remove obsolete defines.
15594 * sysdep.c: Include limits.h unconditionally.
15596 Assume support for memcmp, memcpy, memmove, memset.
15597 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
15598 * regex.c (memcmp, memcpy):
15599 Remove; we assume C89 now.
15601 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
15602 (__malloc_safe_bcopy): Remove; no longer needed.
15604 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
15605 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
15606 well either way, and we prefer signed to unsigned.
15608 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
15610 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
15611 closes the connection while we're reading (bug#9182).
15613 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
15615 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
15616 are specified (Bug#9168).
15618 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
15620 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
15621 Found by GCC static checking and --with-wide-int on a 32-bit host.
15623 2011-07-25 Eli Zaretskii <eliz@gnu.org>
15625 * xdisp.c (compute_display_string_pos): Fix logic of caching
15626 previous display string position. Initialize cached_prev_pos to
15627 -1. Fixes slow-down at the beginning of a buffer.
15629 2011-07-24 Eli Zaretskii <eliz@gnu.org>
15631 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
15632 for attrs[LFACE_FONTSET_INDEX].
15634 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
15636 * xml.c (parse_region): Remove unused local
15637 that was recently introduced.
15639 2011-07-23 Eli Zaretskii <eliz@gnu.org>
15641 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
15642 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
15644 * xdisp.c (move_it_in_display_line_to): Record the best matching
15645 position for TO_CHARPOS while scanning the line, and restore it on
15646 exit if none of the characters scanned was an exact match.
15647 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
15648 when exact match is impossible due to invisible text, and the
15649 lines are truncated.
15651 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
15653 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
15656 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15658 Fix a significant slow-down of cursor motion with C-n, C-p,
15659 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
15660 auto-repeat under bidi redisplay in fontified buffers.
15661 * xdisp.c (compute_stop_pos_backwards): New function.
15662 (next_element_from_buffer): Call compute_stop_pos_backwards to
15663 find a suitable prev_stop when we find ourselves before
15665 (reseat): Don't look for prev_stop, as that could mean a very long
15667 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
15668 <cached_disp_overlay_modiff>: Cache for last found display string
15670 (compute_display_string_pos): Return the cached position if asked
15671 about the same buffer in the same area of character positions, and
15672 the buffer wasn't changed since the time the display string
15673 position was cached.
15675 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15677 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
15678 is an integer, which is important for empty lines. (Bug#9149)
15680 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
15682 * frame.c (Fmodify_frame_parameters): In tty case, update the
15683 default face if necessary (Bug#4238).
15685 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
15687 * editfns.c (Fstring_to_char): No need to explain what a character
15688 is in the docstring (Bug#6576).
15690 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15692 * xml.c (parse_region): Make sure we always return a tree.
15694 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
15696 * xml.c (parse_region): If a document contains only comments,
15699 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15701 * xml.c (make_dom): Return comments, too.
15703 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
15706 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
15707 and the surrounding thread.
15708 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
15709 rather than fgets, and retry after EINTR. Otherwise, 'emacs
15710 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
15712 * s/openbsd.h (BROKEN_SIGIO): Define.
15713 * unexelf.c (unexec) [__OpenBSD__]:
15714 Don't update the .mdebug section of the Alpha COFF symbol table.
15716 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15718 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
15721 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
15723 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
15724 This fixes some race conditions on the permissions of any newly
15727 * alloc.c (valid_pointer_p): Use pipe, not open.
15728 This fixes some permissions issues when debugging.
15730 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
15731 If fchown fails to set both uid and gid, try to set just gid,
15732 as that is sometimes allowed. Adjust the file's mode to eliminate
15733 setuid or setgid bits that are inappropriate if fchown fails.
15735 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
15737 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ

15743 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
15745 * lread.c (read_integer): Unread even EOF character.
15746 (read1): Likewise. Properly record start position of symbol.
15748 * lread.c (read1): Read `#:' as empty uninterned symbol if no
15749 symbol character follows.
15751 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
15753 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
15754 This works around a problem with the previous change to Fcopy_file.
15755 Recent glibc declares fchown with __attribute__((warn_unused_result)),
15756 and without this change, GCC might complain about discarding
15757 fchown's return value.
15759 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
15761 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
15763 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
15765 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
15767 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
15769 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
15770 it's used from the C level.
15772 * process.c: Use the same condition for POLL_FOR_INPUT in both
15773 keyboard.c and process.c (bug#1858).
15775 2011-07-09 Lawrence Mitchell <wence@gmx.li>
15777 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
15778 (Fgnutls_boot): Use it.
15780 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
15782 * doc.c (Fsubstitute_command_keys): Revert last change.
15784 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
15786 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
15787 quotes the next character, and doesn't affect other longer
15788 sequences (bug#8935).
15790 * lread.c (syms_of_lread): Clarify that is isn't only
15791 `eval-buffer' and `eval-defun' that's affected by
15792 `lexical-binding' (bug#8460).
15794 2011-07-15 Eli Zaretskii <eliz@gnu.org>
15796 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
15797 bidi redisplay when a line includes both an image and is truncated.
15799 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
15801 Fix minor problems found by static checking.
15802 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
15803 (elsz): Now a signed constant, not a size_t var. We prefer signed
15804 types to unsigned, to avoid integer comparison confusion. Without
15805 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
15806 "cannot optimize loop, the loop counter may overflow", a symptom
15808 * indent.c (Fvertical_motion): Mark locals as initialized.
15809 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
15811 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
15813 * search.c (Fre_search_backward): Mention `case-fold-search' in
15814 all the re_search_* functions (bug#8138).

15834 buffer position was specified. Initialize paragraph_embedding to
15836 (reseat_to_string): Initialize the bidi iterator.
15837 (display_string): If we need to ignore text properties of
15838 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
15839 original value of -1 will not work with bidi.)
15840 (compute_display_string_pos): First arg is now struct
15841 `text_pos *'; all callers changed. Support display properties on
15843 (compute_display_string_end): Support display properties on Lisp
15845 (init_iterator, reseat_1, reseat_to_string): Initialize the
15846 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
15847 when iterating on a string not from display properties).
15848 (compute_display_string_pos, compute_display_string_end):
15849 Fix calculation of the object to scan. Fixes an error when using
15851 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
15852 base_level_stop; instead, set base_level_stop to BEGV.
15853 Fixes crashes in vertical-motion.
15854 (next_element_from_buffer): Improve commentary for when
15855 the iterator is before prev_stop.
15856 (init_iterator): Initialize bidi_p from the default value of
15857 bidi-display-reordering, not from buffer-local value. Use the
15858 buffer-local value only if initializing for buffer iteration.
15859 (handle_invisible_prop): Support invisible properties on strings
15860 that are being bidi-reordered.
15861 (set_iterator_to_next): Support bidi reordering of C strings and

15868 (init_iterator): Don't initialize it->bidi_p for strings
15870 (reseat_to_string): Initialize it->bidi_p for strings here.

15878 (get_visually_first_element): New function, refactored from common
15879 parts of next_element_from_buffer, next_element_from_string, and
15880 next_element_from_c_string.
15881 (tool_bar_lines_needed, redisplay_tool_bar)
15882 (display_menu_bar): Force left-to-right direction. Add a FIXME
15883 comment for making that be controlled by a user option.
15884 (push_it, pop_it): Save and restore the state of the
15885 bidi iterator. Save and restore the bidi_p flag.

15892 (get_overlay_strings_1, push_display_prop): Set up the bidi
15893 iterator for displaying display or overlay strings.
15894 (forward_to_next_line_start): Don't use the shortcut if
15896 (back_to_previous_visible_line_start): If handle_display_prop
15897 pushed the iterator stack, restore the internal state of the bidi
15898 iterator by calling bidi_pop_it same number of times.
15899 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
15900 and we are bidi-iterating, don't decrement the iterator position;
15901 instead, set the first_elt flag in the bidi iterator, to produce
15903 (reseat_1): Remove redundant setting of string_from_display_prop_p.
15904 (push_display_prop): xassert that we are iterating a buffer.
15905 (push_it, pop_it): Save and restore paragraph_embedding member.
15906 (handle_single_display_spec, next_overlay_string)
15907 (get_overlay_strings_1, reseat_1, reseat_to_string)
15908 (push_display_prop): Set up the `unibyte' member of bidi_it.string
15909 correctly. Don't assume unibyte strings are not bidi-reordered.
15910 (compute_display_string_pos)
15911 (compute_display_string_end): Fix handling the case of C string.

15918 property. Fix a typo in popping stretch info. Add an assertion
15919 for verifying that the iterator position is in sync with the bidi
15921 (handle_single_display_spec, get_overlay_strings_1)

15946 displayed in margins. (Bug#8133) (Bug#8867)
15947 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past

15975 changed to -1 and -2, respectively.
15976 (bidi_char_at_pos): New function.
15977 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):

16061 Vx_lost_selection_functions to Frun_hook_with_args.
16063 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
16065 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
16066 The old code sometimes used this field without initializing it.
16068 * alloc.c (gc_sweep): Don't read past end of array.
16069 In theory, the old code could also have corrupted Emacs internals,
16070 though it'd be very unlikely.

16174 sigprocmask is portable only for single-threaded applications, and

16333 (clone_per_buffer_values): Don't assume that

16335 This isn't true in general, and it's particularly not true
16336 if Emacs is configured with --with-wide-int.
16337 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):

16374 Random fixes. E.g., (random) never returned negative values.
16375 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
16376 subseconds part to the entropy, as that's a bit more random.
16377 Prefer signed to unsigned, since the signedness doesn't matter and
16378 in general we prefer signed. When given a limit, use a
16379 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
16380 latter isn't right if USE_2_TAGS_FOR_INTS.
16381 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
16382 not 0..VALMASK. Don't discard "excess" bits that random () returns.

16394 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
16395 This is more efficient than Ffile_directory_p and avoids a minor race.
16397 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
16399 * buffer.c (Foverlay_put): Say what the return value is
16402 * fileio.c (barf_or_query_if_file_exists): Check first if the file
16403 is a directory before asking whether to use the file name

16406 error be more correct.
16408 * fns.c (Frequire): Remove the mention of the .gz files, since
16409 that's installation-specific, but keep the mention of

16422 Qgnutls_bootprop_verify_error (which is no longer used).
16424 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
16425 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
16426 Also (re)move comments that are misplaced or no longer relevant.

16455 * lread.c (syms_of_lread): Mention single symbols defined by

16488 minibuffer-local-filename-must-match-map to Elisp.
16489 (syms_of_keymap): Defsubr make-composed-keymap.

16512 with value as argument.
16513 (init_gsettings): Check that GSETTINGS_SCHEMA exists before calling
16514 g_settings_new (Bug#8967). Do not create gsettings_obj.

16527 * eval.c (struct backtrace): Simplify and port the data structure.
16528 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
16529 signed bit field, as this assumption is not portable and it makes
16530 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
16531 "char debug_on_exit : 1" as this is not portable either; instead,
16532 use the portable "unsigned int debug_on_exit : 1". Remove unused
16533 member evalargs. Remove obsolete comments about cc bombing out.
16535 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

16603 (emacs_fixed_new): Set priv->f to argument.
16604 (emacs_fixed_get_preferred_width)
16605 (emacs_fixed_get_preferred_height): Use min_width/height from
16606 frames size_hint to set minimum and natural (Bug#8919).
16607 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
16608 and use min_width/height from frames size_hint to set
16609 min_width/height (Bug#8919).

16629 Use gnulib's dup2 module instead of rolling our own.
16630 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.

16697 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
16699 Integer and buffer overflow fixes (Bug#8873).
16701 * print.c (printchar, strout): Check for string overflow.
16702 (PRINTPREPARE, printchar, strout):
16703 Don't set size unless allocation succeeds.
16705 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
16706 for sizes. Check for string overflow more accurately.
16707 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
16709 * macros.c: Integer and buffer overflow fixes.
16710 * keyboard.h (struct keyboard.kbd_macro_bufsize):
16711 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

16715 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
16717 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
16719 * lread.c: Integer overflow fixes.
16720 (read_integer): Radix is now EMACS_INT, not int,
16721 to improve quality of diagnostics for out-of-range radices.
16722 Calculate buffer size correctly for out-of-range radices.
16723 (read1): Check for integer overflow in radices, and in
16724 read-circle numbers.
16725 (read_escape): Avoid int overflow.
16726 (Fload, openp, read_buffer_size, read1)
16727 (substitute_object_recurse, read_vector, read_list, map_obarray):
16728 Use ptrdiff_t, not int, for sizes.

16743 2011-06-22 Leo Liu <sdl.web@gmail.com>
16745 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
16746 Move to minibuffer.el.
16748 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
16750 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
16751 The following patches are for when GLYPH_DEBUG && !XASSERT.
16752 * dispextern.h (trace_redisplay_p, dump_glyph_string):
16753 * dispnew.c (flush_stdout):
16754 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
16755 Mark as externally visible.
16756 * dispnew.c (check_window_matrix_pointers): Now static.
16757 * dispnew.c (window_to_frame_vpos):
16758 * xfns.c (unwind_create_frame):
16759 * xterm.c (x_check_font): Remove unused local.
16760 * scroll.c (CHECK_BOUNDS):
16761 * xfaces.c (cache_fache): Rename local to avoid shadowing.
16762 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
16763 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
16764 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
16765 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
16767 (debug_method_add): Use va_list and vsprintf rather than relying
16768 on undefined behavior with wrong number of arguments.
16769 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
16770 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
16771 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
16772 since we're not interested in debugging glyphs with old libraries.
16773 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
16774 GCC 4.6.0's static checking.
16776 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
16778 Integer overflow and signedness fixes (Bug#8873).

16790 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
16792 * xfaces.c (load_pixmap):
16793 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
16794 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
16795 (.bitmaps_last, struct x_output.icon_bitmap):
16796 Use ptrdiff_t, not int, for bitmap indexes.
16797 (x_allocate_bitmap_record): Check for size overflow.
16798 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
16800 Use ptrdiff_t, not int, for overlay counts.
16801 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
16802 * editfns.c (overlays_around, get_pos_property):
16803 * textprop.c (get_char_property_and_overlay):
16804 * xdisp.c (next_overlay_change, note_mouse_highlight):
16805 * xfaces.c (face_at_buffer_position):
16806 * buffer.c (OVERLAY_COUNT_MAX): New macro.
16807 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
16808 (Fnext_overlay_change, Fprevious_overlay_change)
16809 (mouse_face_overlay_overlaps, Foverlays_in):
16810 Use ptrdiff_t, not int, for sizes.
16811 (overlays_at, overlays_in): Check for size-calculation overflow.
16813 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
16815 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
16816 (x_session_initialize): Do not assume string length fits in int.
16818 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
16819 This is unlikely, but can occur if DPI is outlandish.
16821 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
16822 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
16824 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
16825 * xrdb.c (magic_file_p, search_magic_path):
16826 Omit last arg SUFFIX; it was always 0. All callers changed.
16827 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
16829 * xfont.c (xfont_match): Avoid need for strlen.
16831 * xfns.c: Don't assume strlen fits in int.

16834 * xdisp.c (message_log_check_duplicate): Return intmax_t,
16835 not unsigned long, as we prefer signed integers. All callers changed.
16836 Detect integer overflow in repeat count.
16837 (message_dolog): Don't assume print length fits in 39 bytes.
16838 (display_mode_element): Don't assume strlen fits in int.
16840 * termcap.c: Don't assume sizes fit in int and never overflow.
16841 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
16842 (gobble_line): Check for size-calculation overflow.
16844 * minibuf.c (Fread_buffer):
16845 * lread.c (intern, intern_c_string):
16846 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

16859 * filelock.c: Fix some buffer overrun and integer overflow issues.
16860 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
16861 Reformulate so as not to need the command string.
16862 Invoke gzip -cd rather than gunzip, as it's more portable.
16863 (lock_info_type, lock_file_1, lock_file):
16864 Don't assume pid_t and time_t fit in unsigned long.
16865 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
16866 (current_lock_owner): Prefer signed type for sizes.
16867 Use memcpy, not strncpy, where memcpy is what is really wanted.
16868 Don't assume (via atoi) that time_t and pid_t fit in int.
16869 Check for time_t and/or pid_t out of range, e.g., via a network share.
16870 Don't alloca where an auto var works fine.
16872 * fileio.c: Fix some integer overflow issues.
16873 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
16874 Don't assume string length fits in int.
16875 (directory_file_name): Don't assume string length fits in long.
16876 (make_temp_name): Don't assume pid fits in int, or that its print
16877 length is less than 20.
16879 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
16881 * coding.c (make_subsidiaries): Don't assume string length fits in int.

16889 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
16890 (main): Don't invoke strlen when not needed.

16896 (Fgetenv_internal):
16897 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
16899 * lread.c (invalid_syntax): Omit length argument.
16900 All uses changed. This doesn't fix a bug, but it simplifies the
16901 code away from its former Hollerith-constant appearance, and it's
16902 one less 'int' to worry about when looking at integer-overflow issues.
16903 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
16905 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
16906 This didn't break anything, but it didn't help either.
16907 It's confusing to put a bogus integer in a place where the actual
16908 value does not matter.
16909 (LIST_END_P): Remove unused macro and its bogus comment.
16910 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
16912 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
16913 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
16915 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
16916 We prefer signed types, and the value cannot exceed the EMACS_INT
16917 range anyway (because otherwise the length would not be representable).
16918 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
16919 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
16920 This avoids a GCC warning when WIDE_EMACS_INT.
16922 * indent.c (sane_tab_width): New function.
16923 (current_column, scan_for_column, Findent_to, position_indentation)
16924 (compute_motion): Use it. This is just for clarity.
16925 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
16927 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
16929 * lisp.h (lint_assume): New macro.
16930 * composite.c (composition_gstring_put_cache):
16931 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
16933 * editfns.c, insdel.c:
16934 Omit unnecessary forward decls, to simplify future changes.
16936 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
16938 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
16940 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
16941 Use much-faster test for byte-length change.
16942 Don't assume string byte-length fits in 'int'.
16943 Check that character arg fits in 'int'.
16944 (mapcar1): Declare byte as byte, for clarity.
16946 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
16948 * fns.c (concat): Catch string overflow earlier.
16949 Do not rely on integer wraparound.
16951 * dispextern.h (struct it.overlay_strings_charpos)
16952 (struct it.selective): Now EMACS_INT, not int.
16953 * xdisp.c (forward_to_next_line_start)
16954 (back_to_previous_visible_line_start)
16955 (reseat_at_next_visible_line_start, next_element_from_buffer):
16956 Don't arbitrarily truncate the value of 'selective' to int.
16958 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
16960 * composite.c: Don't truncate sizes to 'int'.
16961 (composition_gstring_p, composition_reseat_it)
16962 (composition_adjust_point): Use EMACS_INT, not int.
16963 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
16964 not EMACS_UINT, for indexes.
16966 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
16968 * buffer.c: Include <verify.h>.
16969 (struct sortvec.priority, struct sortstr.priority):
16970 Now EMACS_INT, not int.
16971 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
16972 (struct sortstr.size, record_overlay_string)
16973 (struct sortstrlist.size, struct sortlist.used):
16974 Don't truncate size to int.
16975 (record_overlay_string): Check for size-calculation overflow.
16976 (init_buffer_once): Check at compile-time, not run-time.
16978 2011-06-22 Jim Meyering <meyering@redhat.com>
16980 Don't leak an XBM-image-sized buffer
16981 * image.c (xbm_load): Free the image buffer after using it.
16983 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
16986 * composite.c (find_automatic_composition): Omit needless 'return 0;'
16987 that Sun C diagnosed.
16988 * fns.c (secure_hash): Fix pointer signedness issue.
16989 * intervals.c (static_offset_intervals): New function.
16990 (offset_intervals): Use it.
16992 2011-06-21 Leo Liu <sdl.web@gmail.com>
16995 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
16998 * fns.c (secure_hash): Rename from crypto_hash_function and change
16999 the first arg to accept symbols.
17000 (Fsecure_hash): New primitive.
17001 (syms_of_fns): New symbols.
17003 2011-06-20 Deniz Dogan <deniz@dogan.se>
17005 * process.c (Fset_process_buffer): Clarify return value in
17008 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
17010 * dispnew.c (add_window_display_history): Use BVAR.
17012 * xdisp.c (debug_method_add): Use BVAR.
17013 (check_window_end, dump_glyph_matrix, dump_glyph)
17014 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
17016 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
17019 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
17020 check till after the cache is created in init_frame_faces.
17022 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
17024 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
17026 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
17028 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
17029 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
17030 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
17032 Improve buffer-overflow checking (Bug#8873).
17033 * fileio.c (Finsert_file_contents):
17034 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
17035 Remove the old (too-loose) buffer overflow checks.
17036 They weren't needed, since make_gap checks for buffer overflow.
17037 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
17038 The old code merely checked for Emacs fixnum overflow, and relied
17039 on undefined (wraparound) behavior. The new code avoids undefined
17040 behavior, and also checks for ptrdiff_t and/or size_t overflow.
17042 * editfns.c (Finsert_char): Don't dump core with very negative counts.
17043 Tune. Don't use wider integers than needed. Don't use alloca.
17044 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
17046 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
17048 * insdel.c, lisp.h (buffer_overflow): New function.
17049 (insert_from_buffer_1, replace_range, replace_range_2):
17050 * insdel.c (make_gap_larger):
17051 * editfns.c (Finsert_char):
17052 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
17054 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
17056 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
17058 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
17060 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
17061 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
17063 * fileio.c: Don't assume EMACS_INT fits in off_t.
17064 (emacs_lseek): New static function.
17065 (Finsert_file_contents, Fwrite_region): Use it.
17066 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
17068 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
17070 * fns.c: Don't overflow int when computing a list length.
17071 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
17072 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
17073 truncation on 64-bit hosts. Check for QUIT every
17074 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
17075 faster and is responsive enough.
17076 (Flength): Report an error instead of overflowing an integer.
17077 (Fsafe_length): Return a float if the value is not representable
17078 as a fixnum. This shouldn't happen except in contrived situations.
17079 (Fnthcdr, Fsort): Don't assume list length fits in int.
17080 (Fcopy_sequence): Don't assume vector length fits in int.
17082 * alloc.c: Check that resized vectors' lengths fit in fixnums.
17083 (header_size, word_size): New constants.
17084 (allocate_vectorlike): Don't check size overflow here.
17085 (allocate_vector): Check it here instead, since this is the only
17086 caller of allocate_vectorlike that could cause overflow.
17087 Check that the new vector's length is representable as a fixnum.
17089 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
17090 The previous code was bogus. For example, next_almost_prime (32)
17091 returned 39, which is undesirable as it is a multiple of 3; and
17092 next_almost_prime (24) returned 25, which is a multiple of 5 so
17093 why was the code bothering to check for multiples of 7?
17095 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
17097 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
17099 Variadic C functions now count arguments with ptrdiff_t.
17100 This partly undoes my 2011-03-30 change, which replaced int with size_t.
17101 Back then I didn't know that the Emacs coding style prefers signed int.
17102 Also, in the meantime I found a few more instances where arguments
17103 were being counted with int, which may truncate counts on 64-bit
17104 machines, or EMACS_INT, which may be unnecessarily wide.
17105 * lisp.h (struct Lisp_Subr.function.aMANY)
17106 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
17107 Arg counts are now ptrdiff_t, not size_t.
17108 All variadic functions and their callers changed accordingly.
17109 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
17110 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
17111 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
17112 * callint.c (Fcall_interactively): Check arg count for overflow,
17113 to avoid potential buffer overrun. Use signed char, not 'int',
17114 for 'varies' array, so that we needn't bother to check its size
17115 calculation for overflow.
17116 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
17117 * eval.c (apply_lambda):
17118 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
17119 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
17120 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
17122 * callint.c (Fcall_interactively): Don't use index var as event count.
17124 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
17125 * mem-limits.h (SIZE): Remove; no longer used.
17127 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
17129 Remove unnecessary casts.
17130 * xterm.c (x_term_init):
17131 * xfns.c (x_set_border_pixel):
17132 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
17133 These aren't needed now that we assume ANSI C.
17135 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
17136 It's more likely to cause problems (due to unsigned overflow)
17139 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
17141 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
17143 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
17145 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
17147 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
17149 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
17151 GLYPH_CODE_FACE returns EMACS_INT, not int.
17152 * dispextern.h (merge_faces):
17153 * xfaces.c (merge_faces):
17154 * xdisp.c (get_next_display_element, next_element_from_display_vector):
17155 Don't assume EMACS_INT fits in int.
17157 * character.h (CHAR_VALID_P): Remove unused parameter.
17158 * fontset.c, lisp.h, xdisp.c: All uses changed.
17160 * editfns.c (Ftranslate_region_internal): Omit redundant test.
17162 * fns.c (concat): Minor tuning based on overflow analysis.
17163 This doesn't fix any bugs. Use int to hold character, instead
17164 of constantly refetching from Emacs object. Use XFASTINT, not
17165 XINT, for value known to be a character. Don't bother comparing
17166 a single byte to 0400, as it's always less.
17168 * floatfns.c (Fexpt):
17169 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
17171 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
17174 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
17176 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
17177 Without this fix, on a 64-bit host (aset S 0 4294967386) would
17178 incorrectly succeed when S was a string, because 4294967386 was
17179 truncated before it was used.
17181 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
17182 Otherwise, an out-of-range integer could cause undefined behavior
17185 * composite.c: Use int, not EMACS_INT, for characters.
17186 (fill_gstring_body, composition_compute_stop_pos): Use int, not
17187 EMACS_INT, for values that are known to be in character range.
17188 This doesn't fix any bugs but is the usual style inside Emacs and
17189 may generate better code on 32-bit machines.
17191 Make sure a 64-bit char is never passed to ENCODE_CHAR.
17192 This is for reasons similar to the recent CHAR_STRING fix.
17193 * charset.c (Fencode_char): Check that character arg is actually
17194 a character. Pass an int to ENCODE_CHAR.
17195 * charset.h (ENCODE_CHAR): Verify that the character argument is no
17196 wider than 'int', as a compile-time check to prevent future regressions
17199 * character.c (char_string): Remove unnecessary casts.
17201 Make sure a 64-bit char is never passed to CHAR_STRING.
17202 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
17203 by silently ignoring the top 32 bits, allowing some values
17204 that were far too large to be valid characters.
17205 * character.h: Include <verify.h>.
17206 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
17207 arguments are no wider than unsigned, as a compile-time check
17208 to prevent future regressions in this area.
17210 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
17211 (Fsubst_char_in_region):
17213 * xdisp.c (decode_mode_spec_coding):
17214 Adjust to CHAR_STRING's new requirement.
17215 * editfns.c (Finsert_char, Fsubst_char_in_region):
17216 * fns.c (concat): Check that character args are actually
17217 characters. Without this test, these functions did the wrong
17218 thing with wildly out-of-range values on 64-bit hosts.
17220 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
17221 These casts should not be needed on 32-bit hosts, either.
17222 * keyboard.c (read_char):
17223 * lread.c (Fload): Remove casts to unsigned.
17225 * lisp.h (UNSIGNED_CMP): New macro.
17226 This fixes comparison bugs on 64-bit hosts.
17227 (ASCII_CHAR_P): Use it.
17228 * casefiddle.c (casify_object):
17229 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
17230 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
17231 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
17232 * dispextern.h (FACE_FROM_ID):
17233 * keyboard.c (read_char): Use UNSIGNED_CMP.
17235 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
17236 not to EMACS_INT, to avoid GCC warning.
17238 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
17240 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
17241 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
17242 isn't needed on 32-bit machines.
17244 * buffer.c (Fgenerate_new_buffer_name):
17245 Use EMACS_INT for count, not int.
17246 (advance_to_char_boundary): Return EMACS_INT, not int.
17248 * data.c (Qcompiled_function): Now static.
17250 * window.c (window_body_lines): Now static.
17252 * image.c (gif_load): Rename local to avoid shadowing.
17254 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
17255 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
17256 * alloc.c (make_save_value): Integer argument is now of type
17257 ptrdiff_t, not int.
17258 (mark_object): Use ptrdiff_t, not int.
17259 * lisp.h (pD): New macro.
17260 * print.c (print_object): Use it.
17262 * alloc.c: Use EMACS_INT, not int, to count objects.
17263 (total_conses, total_markers, total_symbols, total_vector_size)
17264 (total_free_conses, total_free_markers, total_free_symbols)
17265 (total_free_floats, total_floats, total_free_intervals)
17266 (total_intervals, total_strings, total_free_strings):
17267 Now EMACS_INT, not int. All uses changed.
17268 (Fgarbage_collect): Compute overall total using a double, so that
17269 integer overflow is less likely to be a problem. Check for overflow
17270 when converting back to an integer.
17271 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
17272 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
17273 These were 'int' variables that could overflow on 64-bit hosts;
17274 they were never used, so remove them instead of repairing them.
17275 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
17276 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
17277 Previously, this ceilinged at INT_MAX, but that doesn't work on
17279 (allocate_pseudovector): Don't use EMACS_INT when int would do.
17281 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
17282 (allocate_vectorlike): Check for ptrdiff_t overflow.
17283 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
17284 when a (possibly-narrower) signed value would do just as well.
17285 We prefer using signed arithmetic, to avoid comparison confusion.
17287 * alloc.c: Catch some string size overflows that we were missing.
17288 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
17289 for convenience in STRING_BYTES_MAX.
17290 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
17291 The definition here is exact; the one in lisp.h was approximate.
17292 (allocate_string_data): Check for string overflow. This catches
17293 some instances we weren't catching before. Also, it catches
17294 size_t overflow on (unusual) hosts where SIZE_MAX <= min
17295 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
17296 and ptrdiff_t and EMACS_INT are both 64 bits.
17298 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
17299 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
17300 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
17302 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
17304 * alloc.c (Fmake_string): Check for out-of-range init.
17306 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
17308 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
17310 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
17312 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
17313 xg_get_default_scrollbar_width.
17315 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
17316 (int_gtk_range_get_value): Move to the scroll bar part of the file.
17317 (style_changed_cb): Call update_theme_scrollbar_width and call
17318 x_set_scroll_bar_default_width and xg_frame_set_char_size for
17319 all frames (Bug#8505).
17320 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
17321 Call gtk_window_set_resizable if HAVE_GTK3.
17322 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
17323 and height if HAVE_GTK3 (Bug#8505).
17324 (scroll_bar_width_for_theme): New variable.
17325 (update_theme_scrollbar_width): New function.
17326 (xg_get_default_scrollbar_width): Move code to
17327 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
17328 (xg_initialize): Call update_theme_scrollbar_width.
17330 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
17332 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
17334 2011-06-12 Martin Rudalics <rudalics@gmx.at>
17336 * frame.c (make_frame): Call other_buffer_safely instead of
17339 * window.c (temp_output_buffer_show): Call display_buffer with
17340 second argument Vtemp_buffer_show_specifiers and reset latter
17341 immediately after the call.
17342 (Vtemp_buffer_show_specifiers): New variable.
17343 (auto_window_vscroll_p, next_screen_context_lines)
17344 (Vscroll_preserve_screen_position): Remove leading asterisks from
17347 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
17349 Fix minor problems found by GCC 4.6.0 static checking.
17350 * buffer.c (Qclone_number): Remove for now, as it's unused.
17351 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
17352 (record_buffer): Remove unused local.
17353 * frame.c (other_visible_frames, frame_buffer_list): Now static.
17354 (set_frame_buffer_list): Remove; unused.
17355 * frame.h (other_visible_frames): Remove decl.
17356 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
17357 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
17358 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
17360 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
17361 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
17362 Define only if HAVE_GPM.
17363 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
17364 (update_hints_inhibit): Remove; never set. All uses removed.
17365 * widgetprv.h (emacsFrameClassRec): Remove decl.
17366 * window.c (delete_deletable_window): Now returns void, since it
17367 wasn't returning anything.
17368 (compare_window_configurations): Remove unused locals.
17369 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
17370 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.

17838 New error handlers.
17839 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
17840 Obey Vx_select_enable_clipboard_manager. Catch errors in
17841 x_clipboard_manager_save (Bug#8779).
17842 (Vx_select_enable_clipboard_manager): New variable.
17843 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
17845 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
17847 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
17849 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17851 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
17852 in the current matrix if keep_current_p is non-zero.

17856 * bidi.c (bidi_level_of_next_char): Fix last change.
17858 2011-06-03 Eli Zaretskii <eliz@gnu.org>
17860 Support bidi reordering of text covered by display properties.
17862 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
17863 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
17864 (bidi_cache_search, bidi_cache_iterator_state)
17865 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
17866 (bidi_level_of_next_char, bidi_move_to_visually_next):
17867 Support character positions inside a run of characters covered by a
17869 (bidi_paragraph_init, bidi_resolve_explicit_1)
17870 (bidi_level_of_next_char): Call bidi_fetch_char and
17871 bidi_fetch_char_advance instead of FETCH_CHAR and
17872 FETCH_CHAR_ADVANCE.
17873 (bidi_init_it): Initialize new members.
17874 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
17876 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
17877 instead of using explicit *_CHAR codes.
17878 (bidi_resolve_explicit, bidi_resolve_weak):
17879 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
17880 bidirectional text is supported only in multibyte buffers.
17881 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
17882 it to initialize the frame_window_p member of struct bidi_it.
17883 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
17884 (bidi_resolve_explicit, bidi_resolve_weak)

17886 bidi_it->nchars is non-positive.
17887 (bidi_level_of_next_char): Don't try to lookup the cache for the
17888 next/previous character if nothing is cached there yet, or if we
17889 were just reseat()'ed to a new position.
17891 * xdisp.c (set_cursor_from_row): Set start and stop points
17892 according to the row's direction when priming the loop that looks
17893 for the glyph on which to display cursor.
17894 (single_display_spec_intangible_p): Function deleted.
17895 (display_prop_intangible_p): Reimplement to call
17896 handle_display_spec instead of single_display_spec_intangible_p.
17897 Accept 3 additional arguments needed by handle_display_spec.
17898 This fixes incorrect cursor motion across display property with complex
17899 values: lists, `(when COND...)' forms, etc.
17900 (single_display_spec_string_p): Support property values that are
17901 lists with the argument STRING its top-level element.
17902 (display_prop_string_p): Fix the condition for processing a
17903 property that is a list to be consistent with handle_display_spec.
17904 (handle_display_spec): New function, refactored from the
17905 last portion of handle_display_prop.
17906 (compute_display_string_pos): Accept additional argument
17907 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
17908 value of a `display' property is a "replacing spec".
17909 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
17910 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
17911 the display property, but just return a value indicating whether
17912 the display property will replace the characters it covers.
17913 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
17914 frame_window_p members of struct bidi_it.
17915 (compute_display_string_pos, compute_display_string_end):
17917 (push_it): Accept second argument POSITION, where pop_it should
17918 jump to continue iteration.
17919 (reseat_1): Initialize bidi_it.disp_pos.
17921 * keyboard.c (adjust_point_for_property): Adjust the call to
17922 display_prop_intangible_p to its new signature.
17924 * dispextern.h (struct bidi_it): New member frame_window_p.
17925 (bidi_init_it): Update prototypes.
17926 (display_prop_intangible_p): Update prototype.
17927 (compute_display_string_pos, compute_display_string_end):
17928 Declare prototypes.
17929 (struct bidi_it): New members nchars and disp_pos. ch_len is now
17932 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
17934 Malloc failure behavior now depends on size of allocation.
17935 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
17936 * lisp.h: Change signatures accordingly.
17937 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
17938 All callers changed. (Bug#8762)
17940 * gnutls.c: Use Emacs's memory allocators.
17941 Without this change, the gnutls library would invoke malloc etc.
17942 directly, which causes problems on non-SYNC_INPUT hosts, and which
17943 runs afoul of improving memory_full behavior. (Bug#8761)
17944 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
17945 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
17946 xfree instead of the default malloc, realloc, free.
17947 (Fgnutls_boot): No need to check for memory allocation failure,
17948 since xmalloc does that for us.
17950 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
17951 * category.c (hash_get_category_set):
17952 * ccl.c (ccl_driver):
17953 * charset.c (Fdefine_charset_internal):

17963 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
17964 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
17965 (Fsxhash, Fgethash, Fputhash, Fmaphash):
17966 * image.c (make_image, search_image_cache, lookup_image)
17967 (xpm_put_color_table_h):
17968 * lisp.h (struct Lisp_Hash_Table):
17969 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
17970 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
17971 for hashes and hash indexes, instead of 'unsigned' and 'int'.
17972 * alloc.c (allocate_vectorlike):
17973 Check for overflow in vector size calculations.
17974 * ccl.c (ccl_driver):
17975 Check for overflow when converting EMACS_INT to int.
17976 * fns.c, image.c: Remove unnecessary static decls that would otherwise
17977 need to be updated by these changes.
17978 * fns.c (make_hash_table, maybe_resize_hash_table):
17979 Check for integer overflow with large hash tables.
17980 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
17981 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
17982 (SXHASH_REDUCE): New macro.
17983 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
17984 Use it instead of discarding useful hash info with large hash values.
17985 (sxhash_float): New function.
17986 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
17987 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
17988 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
17989 Rewrite to use FIXNUM_BITS, as this simplifies things.
17990 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
17991 Adjust signatures to match updated version of code.
17992 (consing_since_gc): Now EMACS_INT, since a single hash table can
17993 use more than INT_MAX bytes.
17995 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
17997 Make it possible to build with GCC-4.6+ -O2 -flto.
17999 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
18001 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
18003 * minibuf.c (get_minibuffer, read_minibuf_unwind):
18004 Call minibuffer-inactive-mode.
18006 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
18008 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
18009 Update dependencies.
18011 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18013 * data.c (init_data): Remove code for UTS, this system is not
18016 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18018 Don't force ./temacs to start in terminal mode.
18020 * frame.c (make_initial_frame): Initialize faces in all cases, not
18021 only when CANNOT_DUMP is defined.
18022 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
18024 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18026 * dispnew.c (add_window_display_history): Use const for the string
18027 pointer. Remove declaration, not needed.
18029 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18031 Use 'inline', not 'INLINE'.
18032 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
18033 * alloc.c, fontset.c (INLINE): Remove.
18034 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
18035 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
18036 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
18037 * gmalloc.c (register_heapinfo): Use inline unconditionally.
18038 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
18040 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18042 Make it possible to run ./temacs.
18044 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
18045 syms_of_callproc does the same thing. Remove test for
18046 "initialized", do it in the caller.
18047 * emacs.c (main): Avoid calling set_initial_environment when dumping.
18049 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
18051 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
18052 (read_minibuf): Use get_minibuffer.
18053 (syms_of_minibuf): Use DEFSYM.
18054 (Qmetadata): New var.
18055 * data.c (Qbuffer): Don't make it static.
18056 (syms_of_data): Use DEFSYM.
18058 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18060 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
18061 (CCL_CODE_MIN): New macro.
18063 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
18065 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
18067 * eval.c (Qdebug): Now static.
18068 * lisp.h (Qdebug): Remove decl. This reverts a part of the
18069 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
18070 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
18072 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18074 * image.c: Various fixes to ImageMagick code comments.
18075 (Fimagemagick_types): Doc fix.
18077 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
18079 Minor fixes prompted by GCC 4.6.0 warnings.
18081 * xselect.c (converted_selections, conversion_fail_tag): Now static.
18083 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
18084 (x_clipboard_manager_save_all): Move extern decl to ...
18085 * xterm.h: ... here, so that it can be checked for consistency.
18087 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18089 * xselect.c (x_clipboard_manager_save_frame)
18090 (x_clipboard_manager_save_all): New functions.
18091 (Fx_clipboard_manager_save): Lisp function deleted.
18093 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
18094 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
18096 * xterm.h: Update prototype.
18098 2011-05-28 William Xu <william.xwl@gmail.com>
18100 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
18101 exiting (Bug#8239).
18103 2011-05-28 Jim Meyering <meyering@redhat.com>
18105 Avoid a sign-extension bug in crypto_hash_function.
18106 * fns.c (to_uchar): Define.
18107 (crypto_hash_function): Use it to convert some newly-signed
18108 variables to unsigned, to avoid sign-extension bugs. For example,
18109 without this change, (md5 "truc") would evaluate to
18110 45723a2aff78ff4fff7fff1114760e62 rather than the expected
18111 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
18112 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
18114 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18116 Integer overflow fixes.
18118 * dbusbind.c: Serial number integer overflow fixes.
18119 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
18120 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
18121 to hold a serial number that is too large for a fixnum.
18122 (Fdbus_method_return_internal, Fdbus_method_error_internal):
18123 Check for serial numbers out of range. Decode any serial number
18124 that was so large that it became a float. (Bug#8722)
18126 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
18127 (Fdbus_call_method, Fdbus_call_method_asynchronously):
18128 Use XFASTINT rather than XUINT when numbers are nonnegative.
18129 (xd_append_arg, Fdbus_method_return_internal):
18130 (Fdbus_method_error_internal): Likewise. Also, for unsigned
18131 arguments, check that Lisp number is nonnegative, rather than
18132 silently wrapping negative numbers around. (Bug#8722)
18133 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
18136 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
18138 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
18140 ccl: Add integer overflow checks.
18141 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
18142 (IN_INT_RANGE): New macros.
18143 (ccl_driver): Use them to check for integer overflow when
18144 decoding a CCL program. Many of the new checks are whether XINT (x)
18145 fits in int; it doesn't always, on 64-bit hosts. The new version
18146 doesn't catch all possible integer overflows, but it's an
18147 improvement. (Bug#8719)
18149 * alloc.c (make_event_array): Use XINT, not XUINT.
18150 There's no need for unsigned here.
18152 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
18153 This follows up to the 2011-05-06 change that substituted uintptr_t
18154 for EMACS_INT. This case wasn't caught back then.
18156 Rework Fformat to avoid integer overflow issues.
18157 * editfns.c: Include <float.h> unconditionally, as it's everywhere
18158 now (part of C89). Include <verify.h>.
18159 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
18160 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
18161 (Fformat): Avoid the prepass trying to compute sizes; it was only
18162 approximate and thus did not catch overflow reliably. Instead, walk
18163 through the format just once, formatting and computing sizes as we go,
18164 checking for integer overflow at every step, and allocating a larger
18165 buffer as needed. Keep track separately whether the format is
18166 multibyte. Keep only the most-recently calculated precision, rather
18167 than them all. Record whether each argument has been converted to
18168 string. Use EMACS_INT, not int, for byte and char and arg counts.
18169 Support field widths and precisions larger than INT_MAX. Avoid
18170 sprintf's undefined behavior with conversion specifications such as %#d
18171 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
18172 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
18173 formatting out-of-range floating point numbers with int
18174 formats. (Bug#8668)
18176 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
18178 * data.c: Avoid integer truncation in expressions involving floats.
18179 * data.c: Include <intprops.h>.
18180 (arith_driver): When there's an integer overflow in an expression
18181 involving floating point, convert the integers to floating point
18182 so that the resulting value does not suffer from catastrophic
18183 integer truncation. For example, on a 64-bit host (* 4
18184 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
18185 Do not rely on undefined behavior after integer overflow.
18187 merge count_size_as_multibyte, parse_str_to_multibyte
18188 * character.c, character.h (count_size_as_multibyte):
18189 Rename from parse_str_to_multibyte; all uses changed.
18190 Check for integer overflow.
18191 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
18192 since it's now a duplicate of the other. This is more of
18193 a character than a buffer op, so better that it's in character.c.
18194 * fns.c, print.c: Adjust to above changes.
18196 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
18198 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
18200 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18202 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18203 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
18204 (x_clipboard_manager_save): Now static.
18205 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
18207 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18208 (crypto_hash_function): Now static.
18209 Fix pointer signedness problems. Avoid unnecessary initializations.
18211 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
18213 * termhooks.h (Vselection_alist): Make it terminal-local.
18215 * terminal.c (create_terminal): Initialize it.
18217 * xselect.c: Support for clipboard managers.
18218 (Vselection_alist): Move to termhooks.h as terminal-local var.
18219 (LOCAL_SELECTION): New macro.
18220 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
18221 (symbol_to_x_atom): Remove gratuitous arg.
18222 (x_handle_selection_request, lisp_data_to_selection_data)
18223 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
18224 (x_own_selection, x_get_local_selection, x_convert_selection):
18225 New arg, specifying work frame. Use terminal-local Vselection_alist.
18226 (some_frame_on_display): Delete unused function.
18227 (Fx_own_selection_internal, Fx_get_selection_internal)
18228 (Fx_disown_selection_internal, Fx_selection_owner_p)
18229 (Fx_selection_exists_p): New optional frame arg.
18230 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
18231 (x_handle_selection_clear): Don't treat other terminals with the
18232 same keyboard specially. Use the terminal-local Vselection_alist.
18233 (x_clear_frame_selections): Use Frun_hook_with_args.
18235 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
18237 * xterm.h: Add support for those atoms.
18239 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
18241 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
18242 (converted_selections, conversion_fail_tag): New global variables.
18243 (x_selection_request_lisp_error): Free the above.
18244 (x_get_local_selection): Remove unnecessary code.
18245 (x_reply_selection_request): Args changed; handle arbitrary array
18246 of converted selections stored in converted_selections.
18247 Separate the XChangeProperty and SelectionNotify steps.
18248 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
18249 (x_convert_selection): New function.
18250 (x_handle_selection_event): Simplify.
18251 (x_get_foreign_selection): Don't ignore incoming requests while
18252 waiting for an answer; this will fail when we implement
18253 SAVE_TARGETS, and seems unnecessary anyway.
18254 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
18255 (Vx_sent_selection_functions): Doc fix.
18257 2011-05-26 Leo Liu <sdl.web@gmail.com>
18259 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
18261 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18263 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
18265 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
18266 for fringe update if it has periodic bitmap.
18267 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
18268 and fringe_bitmap_periodic_p.
18270 * fringe.c (get_fringe_bitmap_data): New function.
18271 (draw_fringe_bitmap_1, update_window_fringes): Use it.
18272 (update_window_fringes): Record periodicity of fringe bitmap in glyph
18273 row. Mark glyph row for fringe update if periodicity changed.
18275 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
18276 for fringe update unless it has periodic bitmap.
18278 2011-05-25 Kenichi Handa <handa@m17n.org>
18280 * xdisp.c (get_next_display_element): Set correct it->face_id for
18281 a static composition.
18283 2011-05-24 Leo Liu <sdl.web@gmail.com>
18286 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
18288 * fns.c (crypto_hash_function, Fsha1): New function.
18289 (Fmd5): Use crypto_hash_function.
18290 (syms_of_fns): Add Ssha1.
18292 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18294 * gnutls.c: Remove unused macros.
18295 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
18296 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
18297 Remove macros that are defined and never used.
18298 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
18300 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18302 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
18303 (Fx_get_selection_internal): Minor cleanup.
18304 (Fx_own_selection_internal): Rename arguments for consistency with
18307 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18309 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
18311 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18313 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
18315 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18317 * dispnew.c (scrolling_window): Don't exclude the case that the
18318 last enabled row in the desired matrix touches the bottom boundary.
18320 2011-05-21 Glenn Morris <rgm@gnu.org>
18322 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
18323 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
18324 and add some more files.
18326 2011-05-20 Eli Zaretskii <eliz@gnu.org>
18328 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
18329 report_file_error introduced by the change from 2011-05-07.
18331 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
18333 * systime.h (Time): Define only if emacs is defined.
18334 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
18335 where the include path doesn't have X11/X.h by default. See
18336 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
18338 2011-05-20 Kenichi Handa <handa@m17n.org>
18340 * composite.c (find_automatic_composition): Fix previous change.
18342 2011-05-20 Glenn Morris <rgm@gnu.org>
18344 * lisp.mk: New file, split from Makefile.in.
18345 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
18346 (shortlisp): Remove.
18347 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
18349 2011-05-19 Glenn Morris <rgm@gnu.org>
18351 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
18352 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
18353 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
18354 (lisp): Set the order to that of loadup.el.
18355 (shortlisp): Make it a copy of $lisp.
18356 (SOME_MACHINE_LISP): Remove.
18357 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
18358 Use just $shortlisp, not $SOME_MACHINE_LISP too.
18360 2011-05-18 Kenichi Handa <handa@m17n.org>
18362 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
18363 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
18364 (find_automatic_composition): Mostly rewrite for efficiency.
18366 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
18368 * makefile.w32-in: Update dependencies.
18370 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
18372 * menu.c: Include limits.h (fixes the MS-Windows build broken by
18373 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
18375 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
18377 Fix some integer overflow issues, such as string length overflow.
18379 * insdel.c (count_size_as_multibyte): Check for string overflow.
18381 * character.c (lisp_string_width): Check for string overflow.
18382 Use EMACS_INT, not int, for string indexes and lengths; in
18383 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
18384 the resulting string length overflows an EMACS_INT; instead,
18385 report a string overflow if no precision given. When checking for
18386 precision exhaustion, use a check that cannot possibly have
18387 integer overflow. (Bug#8675)
18388 * character.h (lisp_string_width): Adjust to new signature.
18390 * alloc.c (string_overflow): New function.
18391 (Fmake_string): Use it. This doesn't change behavior, but saves
18392 a few bytes and will simplify future changes.
18393 * character.c (string_escape_byte8): Likewise.
18394 * lisp.h (string_overflow): New decl.
18396 Fixups, following up to the user-interface timestamp change.
18397 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
18398 for UI timestamps, instead of unsigned long.
18399 * msdos.c (mouse_get_pos): Likewise.
18400 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
18401 * w32gui.h (Time): Define by including "systime.h" rather than by
18402 declaring it ourselves. (Bug#8664)
18404 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
18405 * image.c (clear_image_cache): Likewise.
18407 * term.c (term_mouse_position): Don't assume time_t wraparound.
18409 Be more systematic about user-interface timestamps.
18410 Before, the code sometimes used 'Time', sometimes 'unsigned long',
18411 and sometimes 'EMACS_UINT', to represent these timestamps.
18412 This change causes it to use 'Time' uniformly, as that's what X uses.
18413 This makes the code easier to follow, and makes it easier to catch
18414 integer overflow bugs such as Bug#8664.
18415 * frame.c (Fmouse_position, Fmouse_pixel_position):
18416 Use Time, not unsigned long, for user-interface timestamps.
18417 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
18418 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
18419 * keyboard.h (last_event_timestamp): Likewise.
18420 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
18421 * menu.h (xmenu_show): Likewise.
18422 * term.c (term_mouse_position): Likewise.
18423 * termhooks.h (struct input_event.timestamp): Likewise.
18424 (struct terminal.mouse_position_hook): Likewise.
18425 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
18426 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
18427 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
18428 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
18429 what it was before.
18430 * menu.h, termhooks.h: Include "systime.h", for Time.
18432 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
18433 Don't assume that the difference between two unsigned long values
18434 can fit into an integer. At this point, we know button_down_time
18435 <= event->timestamp, so the difference must be nonnegative, so
18436 there's no need to cast the result if double-click-time is
18437 nonnegative, as it should be; check that it's nonnegative, just in
18438 case. This bug is triggered when events are more than 2**31 ms
18439 apart (about 25 days). (Bug#8664)
18441 * xselect.c (last_event_timestamp): Remove duplicate decl.
18442 (x_own_selection): Remove needless cast to unsigned long.
18444 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
18445 that always fit in int. Use a sentinel instead of a counter, to
18446 avoid a temp and to allay GCC's concerns about possible int overflow.
18447 * frame.h (struct frame): Use int for menu_bar_items_used
18448 instead of EMACS_INT, since it always fits in int.
18450 * menu.c (grow_menu_items): Check for int overflow.
18452 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
18454 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
18455 Before, the code was not consistent. These values cannot exceed
18456 2**31 - 1 so there's no need to make them unsigned.
18457 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
18458 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
18459 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
18461 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
18463 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
18464 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
18465 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
18466 presumably because the widths might not match.
18468 * window.c (size_window): Avoid needless test at loop start.
18470 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
18472 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
18474 2011-05-12 Drew Adams <drew.adams@oracle.com>
18476 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
18478 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18480 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
18481 `width' to `bar_area_x' and `bar_area_width', respectively.
18482 (x_scroll_run): Take account of fringe background extension.
18484 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
18485 Rename local vars `left' and `width' to `bar_area_x' and
18486 `bar_area_width', respectively.
18487 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
18488 background extension.
18490 2011-05-10 Jim Meyering <meyering@redhat.com>
18492 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
18494 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
18496 * image.c (Finit_image_library): Return t for built-in image types,
18497 like pbm and xbm. (Bug#8640)
18499 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
18501 * w32menu.c (set_frame_menubar): Fix submenu allocation.
18503 2011-05-07 Eli Zaretskii <eliz@gnu.org>
18505 * w32console.c (Fset_screen_color): Doc fix.
18506 (Fget_screen_color): New function.
18507 (syms_of_ntterm): Defsubr it.
18509 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
18510 unlink the temporary file if Fcall_process didn't create it in the
18512 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
18513 child process will be redirected to a file specified with `:file'.
18514 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
18515 cue to call_process_cleanup not to close that handle.
18517 2011-05-07 Ben Key <bkey76@gmail.com>
18519 * makefile.w32-in: The bootstrap-temacs rule now makes use of
18520 one of two shell specific rules, either bootstrap-temacs-CMD or
18521 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
18522 to the previous implementation of the bootstrap-temacs rule.
18523 The bootstrap-temacs-CMD rule is similar to the previous
18524 implementation of the bootstrap-temacs rule except that it
18525 makes use of the ESC_CFLAGS variable instead of the CFLAGS
18528 These changes, along with some changes to nt/configure.bat,
18529 nt/gmake.defs, and nt/nmake.defs, are required to extend my
18530 earlier fix to add support for --cflags and --ldflags options
18531 that include quotes so that it works whether make uses cmd or
18534 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
18536 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
18537 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
18539 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
18540 a string. Handle both cases.
18541 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
18542 (Fdbus_register_method): Use Qinvalid_function.
18544 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18546 * makefile.w32-in: Update dependencies.
18547 (LISP_H): Add inttypes.h and stdin.h.
18548 (PROCESS_H): Add unistd.h.
18550 2011-05-06 Eli Zaretskii <eliz@gnu.org>
18552 * lread.c: Include limits.h (fixes the MS-Windows build broken by
18553 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
18555 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
18557 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
18559 * term.c (vfatal): Remove stray call to va_end.
18560 It's not needed and the C Standard doesn't allow it here anyway.
18562 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
18563 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
18565 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
18568 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
18570 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
18572 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
18574 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
18576 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
18578 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
18579 * charset.c (Fdefine_charset_internal): Don't initialize
18580 charset.code_space[15]. The value was garbage, on hosts with
18581 32-bit int (Bug#8600).
18583 * lread.c (read_integer): Be more consistent with string-to-number.
18584 Use string_to_number to do the actual conversion; this avoids
18585 rounding errors and fixes some other screwups. Without this fix,
18586 for example, #x1fffffffffffffff was misread as -2305843009213693952.
18587 (digit_to_number): Move earlier, for benefit of read_integer.
18588 Return -1 if the digit is out of range for the base, -2 if it is
18589 not a digit in any supported base. (Bug#8602)
18591 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
18593 * dispnew.c (scrolling_window): Return 1 if we scrolled,
18594 to match comment at start of function. This also removes a
18595 GCC warning about overflow in a 32+64-bit port.
18597 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
18599 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
18600 Reported by Stefan Monnier in
18601 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
18602 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18603 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
18605 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
18606 (EMACS_UINTPTR): Likewise, with uintptr_t.
18608 * lisp.h: Prefer 64-bit EMACS_INT if available.
18609 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
18610 on 32-bit hosts that have 64-bit int, so that they can access
18612 However, temporarily disable this change unless the temporary
18613 symbol WIDE_EMACS_INT is defined.
18615 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
18617 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
18618 This removes an assumption that EMACS_INT and long are the same
18619 width as pointers. The assumption is true for Emacs porting targets
18620 now, but we want to make other targets possible.
18621 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
18622 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
18623 In the rest of the code, change types of integers that hold casted
18624 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
18625 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
18626 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
18627 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
18628 No need to cast type when ORing.
18629 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
18630 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
18631 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
18632 assume EMACS_INT is the same width as char *.
18633 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
18634 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
18635 Remove no-longer-needed casts.
18636 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
18637 (xg_tool_bar_help_callback, xg_make_tool_item):
18638 Use EMACS_INTPTR to hold an integer
18639 that will be cast to void *; this can avoid a GCC warning
18640 if EMACS_INT is not the same width as void *.
18641 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
18642 * xdisp.c (display_echo_area_1, resize_mini_window_1):
18643 (current_message_1, set_message_1):
18644 Use a local to convert to proper width without a cast.
18645 * xmenu.c (dialog_selection_callback): Likewise.
18647 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
18648 Also, don't assume VALBITS / RAND_BITS is less than 5,
18649 and don't rely on undefined behavior when shifting a 1 left into
18651 * lisp.h (get_random): Change signature to match.
18653 * lread.c (hash_string): Use size_t, not int, for hash computation.
18654 Normally we prefer signed values; but hashing is special, because
18655 it's better to use unsigned division on hash table sizes so that
18656 the remainder is nonnegative. Also, size_t is the natural width
18657 for hashing into memory. The previous code used 'int', which doesn't
18658 retain enough info to hash well into very large tables.
18659 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
18661 * dbusbind.c: Don't possibly lose pointer info when converting.
18662 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18663 Use XPNTR rather than XHASH, so that the high-order bits of
18664 the pointer aren't lost when converting through void *.
18666 * eval.c (Fautoload): Don't double-shift a pointer.
18668 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
18670 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18672 * gnutls.c (DEF_GNUTLS_FN):
18673 * image.c (DEF_IMGLIB_FN): Make function pointers static.

18751 * process.c: Include lisp.h before w32.h, not after.
18752 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
18753 instead of gnutls_record_check_pending.
18755 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
18757 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
18759 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options

18805 rather than `XVECTOR (FOO)->size'.
18807 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
18808 inttypes.h, as a gnulib replacement is used if it not available in
18811 2011-04-21 Eli Zaretskii <eliz@gnu.org>
18813 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
18814 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
18815 of MOST_POSITIVE_FIXNUM. (Bug#8528)

18818 will grow beyond MOST_POSITIVE_FIXNUM.
18819 (decode_coding_emacs_mule): Abort if there isn't enough place in
18820 charbuf for the composition carryover bytes. Reserve an extra
18821 space for up to 2 characters produced in a loop.

18823 charbuf for the composition carryover bytes.
18825 2011-04-21 Eli Zaretskii <eliz@gnu.org>
18827 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
18828 aborting when %lld or %lll format is passed.
18829 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
18830 %llo or %llx format is passed. (Bug#8545)
18832 * window.c (window_scroll_line_based): Use a marker instead of
18833 simple variables to record original value of point. (Bug#7952)
18835 * doprnt.c (doprnt): Fix the case where a multibyte sequence
18836 produced by %s or %c overflows available buffer space. (Bug#8545)
18838 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
18840 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
18841 (SIZE_MAX): Move defn after all includes, as they might #define it.
18843 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18845 * w32.c (init_environment): Warn about defaulting HOME to C:\.
18847 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18849 * keyboard.c (Qdelayed_warnings_hook): Define.
18850 (command_loop_1): Run `delayed-warnings-hook'
18851 if Vdelayed_warnings_list is non-nil.
18852 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
18853 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
18855 2011-04-28 Eli Zaretskii <eliz@gnu.org>
18857 * doprnt.c (doprnt): Don't return value smaller than the buffer
18858 size if the message was truncated. (Bug#8545).
18860 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18862 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
18863 (Fx_window_property): #if-0 the whole functions, not just the bodies.
18865 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18867 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
18869 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
18871 * makefile.w32-in: Update dependencies.
18873 2011-04-27 Eli Zaretskii <eliz@gnu.org>
18875 Improve `doprnt' and its usage. (Bug#8545)
18876 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
18877 `format_end'. Remove support for %l as a conversion specifier.
18878 Don't use xrealloc. Improve diagnostics when the %l size modifier
18879 is used. Update the commentary.
18881 * eval.c (verror): Simplify calculation of size_t.
18883 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
18886 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
18888 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
18891 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18893 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
18894 This makes this file independent of the recent pseudovector change.
18896 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
18898 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
18900 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
18901 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
18902 Remove unused local.
18903 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
18905 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
18906 GCC 4.6.0 optimizes based on type-based alias analysis.
18907 For example, if b is of type struct buffer * and v of type struct
18908 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
18909 != &v->size, and therefore "v->size = 1; b->size = 2; return
18910 v->size;" must therefore return 1. This assumption is incorrect
18911 for Emacs, since it type-puns struct Lisp_Vector * with many other
18912 types. To fix this problem, this patch adds a new type struct
18913 vectorlike_header that documents the constraints on layout of vectors
18914 and pseudovectors, and helps optimizing compilers not get fooled
18915 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
18916 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
18917 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
18919 (XSETPVECTYPE): Rewrite in terms of new macro.
18920 (XSETPVECTYPESIZE): New macro, specifying both type and size.
18921 This is a bit clearer, and further avoids the possibility of
18922 undesirable aliasing.
18923 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
18924 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
18925 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
18926 since Lisp_Subr is a special case (no "next" field).
18927 (ASIZE): Now uses header.size rather than size.
18928 All previous uses of XVECTOR (foo)->size replaced to use this macro,
18929 to avoid the hassle of writing XVECTOR (foo)->header.size.
18930 (struct vectorlike_header): New type.
18931 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
18932 object, to help avoid aliasing.
18933 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
18934 (SUBRP): Likewise, since Lisp_Subr is a special case.
18935 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
18936 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
18937 (struct Lisp_Hash_Table): Combine first two members into a single
18938 struct vectorlike_header member. All uses of "size" and "next" members
18939 changed to be "header.size" and "header.next".
18940 * buffer.h (struct buffer): Likewise.
18941 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
18942 * frame.h (struct frame): Likewise.
18943 * process.h (struct Lisp_Process): Likewise.
18944 * termhooks.h (struct terminal): Likewise.
18945 * window.c (struct save_window_data, struct saved_window): Likewise.
18946 * window.h (struct window): Likewise.
18947 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
18948 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
18949 * buffer.c (init_buffer_once): Likewise.
18950 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
18952 * process.c (Fformat_network_address): Use local var for size,
18955 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
18957 Make the Lisp reader and string-to-float more consistent (Bug#8525)
18958 * data.c (atof): Remove decl; no longer used or needed.
18959 (digit_to_number): Move to lread.c.
18960 (Fstring_to_number): Use new string_to_number function, to be
18961 consistent with how the Lisp reader treats infinities and NaNs.
18962 Do not assume that floating-point numbers represent EMACS_INT
18963 without losing information; this is not true on most 64-bit hosts.
18964 Avoid double-rounding errors, by insisting on integers when
18965 parsing non-base-10 numbers, as the documentation specifies.
18966 * lisp.h (string_to_number): New decl, replacing ...
18967 (isfloat_string): Remove.
18968 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
18969 (read1): Do not accept +. and -. as integers; this
18970 appears to have been a coding error. Similarly, do not accept
18971 strings like +-1e0 as floating point numbers. Do not report
18972 overflow for integer overflows unless the base is not 10 which
18973 means we have no simple and reliable way to continue.
18974 Break out the floating-point parsing into a new
18975 function string_to_number, so that Fstring_to_number parses
18976 floating point numbers consistently with the Lisp reader.
18977 (digit_to_number): Move here from data.c. Make it static inline.
18978 (E_CHAR, EXP_INT): Remove, replacing with ...
18979 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
18980 (string_to_number): New function, replacing isfloat_string.
18981 This function checks for valid syntax and produces the resulting
18982 Lisp float number too. Rework it so that string-to-number
18983 no longer mishandles examples like "1.0e+". Use strtoumax,
18984 so that overflow for non-base-10 numbers is reported only when
18985 there's no portable and simple way to convert to floating point.
18987 * textprop.c (set_text_properties_1): Rewrite for clarity,
18988 and to avoid GCC warning about integer overflow.
18990 * intervals.h (struct interval): Use EMACS_INT for members
18991 where EMACS_UINT might cause problems. See
18992 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
18993 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
18994 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
18996 (offset_intervals): Tell GCC not to worry about length overflow
18997 when negating a negative length.
18999 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
19000 (overrun_check_free): Likewise.
19002 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
19003 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
19006 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19007 (gnutls_make_error): Rename local to avoid shadowing.
19008 (gnutls_emacs_global_deinit): ifdef out; not used.
19009 (Fgnutls_boot): Use const for pointer to readonly storage.
19010 Comment out unused local. Fix pointer signedness problems.
19012 * lread.c (openp): Don't stuff size_t into an 'int'.
19013 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
19014 about possible signed overflow.
19016 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19017 (GDK_KEY_g): Don't define if already defined.
19018 (xg_prepare_tooltip): Avoid pointer signedness problem.
19019 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
19021 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
19022 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
19024 * xfns.c (Fx_window_property): Simplify a bit,
19025 to make a bit faster and to avoid GCC 4.6.0 warning.
19026 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
19028 * fns.c (internal_equal): Don't assume size_t fits in int.
19030 * alloc.c (compact_small_strings): Tighten assertion a little.
19032 Replace pEd with more-general pI, and fix some printf arg casts.
19033 * lisp.h (pI): New macro, generalizing old pEd macro to other
19034 conversion specifiers. For example, use "...%"pI"d..." rather
19035 than "...%"pEd"...".
19036 (pEd): Remove. All uses replaced with similar uses of pI.
19037 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
19038 * alloc.c (check_pure_size): Don't overflow by converting size to int.
19039 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
19040 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
19041 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
19042 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
19043 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
19045 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
19046 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
19047 * print.c (safe_debug_print, print_object): Likewise.
19048 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
19050 Use pI instead of if-then-else-abort. Use %p to avoid casts,
19051 avoiding the 0 flag, which is not portable.
19052 * process.c (Fmake_network_process): Use pI to avoid cast.
19053 * region-cache.c (pp_cache): Likewise.
19054 * xdisp.c (decode_mode_spec): Likewise.
19055 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
19056 behavior on 64-bit hosts with printf arg.
19057 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
19058 (x_stop_queuing_selection_requests): Likewise.
19059 (x_get_window_property): Don't truncate byte count to an 'int'
19062 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
19063 here, since it parses constructs like leading '-' and spaces,
19064 which are not wanted; and it overflows with large numbers.
19065 Instead, simply match F[0-9]+, which is what is wanted anyway.
19067 * alloc.c: Remove unportable assumptions about struct layout.
19068 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
19069 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
19070 (allocate_vectorlike, make_pure_vector): Use the new macros,
19071 plus offsetof, to remove unportable assumptions about struct layout.
19072 These assumptions hold on all porting targets that I know of, but
19073 they are not guaranteed, they're easy to remove, and removing them
19074 makes further changes easier.
19076 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
19077 This doesn't fix a bug but makes the code clearer.
19078 (string_overrun_cookie): Now const. Use initializers that
19079 don't formally overflow signed char, to avoid warnings.
19080 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
19081 can cause Emacs to crash when string overrun checking is enabled.
19082 (allocate_buffer): Don't assume sizeof (struct buffer) is a
19083 multiple of sizeof (EMACS_INT); it need not be, if
19084 alignof(EMACS_INT) < sizeof (EMACS_INT).
19085 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
19087 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
19089 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
19091 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>

19946 * xdisp.c (redisplay_window): Don't try to determine the character
19947 position of the scroll margin if the window start point w->startp

19950 2011-04-10 Eli Zaretskii <eliz@gnu.org>
19952 Fix write-region and its subroutines for buffers > 2GB.

19985 4.6.0 generate slightly better code.
19987 * ftfont.c: Distingish more carefully between FcChar8 and char.
19988 The previous code passed unsigned char * to a functions like
19989 strlen and xstrcasecmp that expect char *, which does not
19990 conform to the C standard.
19991 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
19992 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
19993 char * when the C standard requires it.
19995 * keyboard.c (read_char): Remove unused var.
19997 * eval.c: Port to Windows vsnprintf (Bug#8435).
19998 Include <limits.h>.
19999 (SIZE_MAX): Define if the headers do not.
20000 (verror): Do not give up if vsnprintf returns a negative count.
20001 Instead, grow the buffer. This ports to Windows vsnprintf, which
20002 does not conform to C99. Problem reported by Eli Zaretskii.
20003 Also, simplify the allocation scheme, by avoiding the need for
20004 calling realloc, and removing the ALLOCATED variable.
20006 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
20008 Remove invocations of doprnt, as Emacs now uses vsnprintf.
20009 But keep the doprint source code for now, as we might revamp it
20010 and use it again (Bug#8435).
20011 * lisp.h (doprnt): Remove.
20012 * Makefile.in (base_obj): Remove doprnt.o.
20013 * deps.mk (doprnt.o): Remove.
20015 error: Print 32- and 64-bit integers portably (Bug#8435).
20016 Without this change, on typical 64-bit hosts error ("...%d...", N)
20017 was used to print both 32- and 64-bit integers N, which relied on
20018 undefined behavior.
20019 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
20020 * lisp.h (error, verror): Mark as printf-like functions.
20021 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
20022 Report overflow in size calculations when allocating printf buffer.
20023 Do not truncate output string at its first null byte.
20024 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
20025 Truncate the output at a character boundary, since vsnprintf does not
20027 * charset.c (check_iso_charset_parameter): Convert internal
20028 character to string before calling 'error', since %c now has the
20030 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
20031 overflow when computing char to be passed to 'error'. Do not
20032 pass Lisp_Object to 'error'; pass the integer instead.
20033 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
20034 formatted with plain %d.
20036 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
20038 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
20040 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
20042 * xterm.c (x_catch_errors): Remove duplicate declaration.
20044 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
20046 * xdisp.c, lisp.h (message_nolog): Remove; unused.
20048 2011-04-10 Jim Meyering <meyering@redhat.com>
20050 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
20051 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
20052 return ssize_t not "int", and use size_t as the buffer length.
20053 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
20054 * gnutls.h: Update declarations.
20055 * process.c (read_process_output): Use ssize_t, to match.
20056 (send_process): Likewise.
20058 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20060 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
20062 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20064 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
20065 Use unsigned char, to match FcChar8 type definition.
20067 * xterm.c (handle_one_xevent):
20068 * xmenu.c (create_and_show_popup_menu):
20069 * xselect.c (x_decline_selection_request)
20070 (x_reply_selection_request): Avoid type-punned deref of X events.
20072 2011-04-09 Eli Zaretskii <eliz@gnu.org>
20074 Fix some uses of `int' instead of EMACS_INT.
20075 * search.c (string_match_1, fast_string_match)
20076 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)

20078 (find_before_next_newline, search_command, Freplace_match)
20079 (Fmatch_data): Make some `int' variables be EMACS_INT.
20081 * xdisp.c (display_count_lines): 3rd argument and return value now
20082 EMACS_INT. All callers changed.
20083 (pint2hrstr): Last argument is now EMACS_INT.
20085 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
20086 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
20087 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
20088 (decode_coding_utf_16, decode_coding_emacs_mule)
20089 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
20090 (decode_coding_ccl, decode_coding_charset)
20091 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
20092 (decode_coding_iso_2022, decode_coding_emacs_mule)

20096 (encode_coding_emacs_mule, encode_invocation_designation)
20097 (encode_designation_at_bol, encode_coding_iso_2022)
20098 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
20099 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
20101 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
20102 (encode_invocation_designation): Last argument P_NCHARS is now
20104 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
20105 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
20107 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
20110 * ccl.c (Fccl_execute_on_string): Declare some variables
20113 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
20115 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
20117 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
20119 * process.c (Fformat_network_address): Doc fix.
20121 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)

20128 instead of using internal_with_output_to_temp_buffer.
20129 (Qhelp_form_show): New var.
20130 (syms_of_keyboard): Use DEFSYM macro.
20132 * print.c (internal_with_output_to_temp_buffer): Function deleted.

20153 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
20155 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
20157 * xdisp.c (vmessage): Mark as a printf-like function.
20159 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.

20165 (tiff_load): Add casts to remove these marks before passing them
20166 to system-supplied API.
20168 * eval.c (Fsignal): Remove excess argument to 'fatal'.
20170 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
20171 This avoids several warnings with gcc -Wstrict-overflow.
20172 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
20173 directly, rather than having caller test rule sign. This avoids
20174 some unnecessary tests.
20175 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
20176 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
20177 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
20179 * xfont.c (xfont_text_extents): Remove var that was set but not used.
20180 (xfont_open): Avoid unnecessary tests.
20182 * composite.c (composition_gstring_put_cache): Use unsigned integer.
20184 * composite.h, composite.c (composition_gstring_put_cache):
20185 Use EMACS_INT, not int, for length.

20188 breaking out part of COMPOSITION_DECODE_RULE.
20189 (COMPOSITION_DECODE_RULE): Use it.
20190 * composite.c (get_composition_id): Remove unused local vars,
20191 by using the new macro.
20193 * textprop.c (set_text_properties_1): Change while to do-while,
20194 since the condition is always true at first.
20196 * intervals.c (graft_intervals_into_buffer): Mark var as used.
20197 (interval_deletion_adjustment): Return unsigned value.
20200 * process.c (list_processes_1, create_pty, read_process_output):
20201 (exec_sentinel): Remove vars that were set but not used.
20202 (create_pty): Remove unnecessary "volatile"s.

20216 * print.c (print_error_message): Avoid int overflow.
20218 * font.c (font_list_entities): Redo for clarity,
20219 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
20221 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
20222 (font_score): Avoid potential overflow in diff calculation.
20224 * fns.c (substring_both): Remove var that is set but not used.
20225 (sxhash): Redo loop for clarity and to avoid wraparound warning.
20227 * eval.c (funcall_lambda): Rename local to avoid shadowing.
20229 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
20230 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
20231 can always succeed if overflow has undefined behavior.
20233 * search.c (boyer_moore, wordify): Remove vars set but not used.
20234 (wordify): Omit three unnecessary tests.
20236 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
20237 All callers changed. This avoids the need for an unused var.
20239 * casefiddle.c (casify_region): Remove var that is set but not used.
20241 * dired.c (file_name_completion): Remove var that is set but not used.
20243 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
20245 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
20246 (Finsert_file_contents): Remove unnecessary code checking fd.
20248 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
20249 Check for integer overflow on size calculations.
20251 * buffer.c (Fprevious_overlay_change): Remove var that is set
20254 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
20255 Remove vars that are set but not used.
20256 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
20257 (timer_check_2): Mark vars as initialized.
20259 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
20261 * image.c (lookup_image): Remove var that is set but not used.
20262 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
20264 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
20265 that are set but not used.
20267 * xfns.c (make_invisible_cursor): Don't return garbage
20268 if XCreateBitmapFromData fails (Bug#8410).
20270 * xselect.c (x_get_local_selection, x_handle_property_notify):
20271 Remove vars that are set but not used.
20273 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
20274 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
20276 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
20277 Remove var that is set but not used.
20278 (scroll_bar_windows_size): Now size_t, not int.
20279 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
20280 Check for overflow.
20282 * xfaces.c (realize_named_face): Remove vars that are set but not used.
20283 (map_tty_color) [!defined MSDOS]: Likewise.
20285 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
20287 * coding.c: Remove vars that are set but not used.
20288 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
20289 All callers changed.
20290 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
20291 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
20292 (decode_coding_charset): Remove vars that are set but not used.
20294 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
20295 that is set but not used.
20297 * print.c (print_object): Remove var that is set but not used.
20299 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
20300 The gnulib version avoids calling malloc in the usual case,
20301 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
20302 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
20303 * filelock.c (current_lock_owner): Likewise.
20304 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
20305 * sysdep.c: Include allocator.h, careadlinkat.h.
20306 (emacs_no_realloc_allocator): New static constant.
20307 (emacs_readlink): New function.
20308 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
20309 ../lib/careadlinkat.h.
20311 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
20313 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
20314 first non-nil return value).
20316 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
20318 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
20319 if not defined (Bug#8403).

20328 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
20329 and thereabouts. All callers changed.
20330 (get_per_char_metric): Remove parameter `f', unused since
20331 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
20333 2011-04-02 Jim Meyering <meyering@redhat.com>
20335 do not dereference NULL upon failed strdup
20336 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
20337 (ns_get_family): Likewise.
20339 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
20341 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
20343 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
20345 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
20348 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
20350 Add lexical binding.
20352 * window.c (Ftemp_output_buffer_show): New fun.
20353 (Fsave_window_excursion):

20361 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
20363 (syms_of_lread): Declare `lexical-binding'.
20365 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
20367 * keyboard.c (eval_dyn): New fun.
20368 (menu_item_eval_property): Use it.
20370 * image.c (parse_image_spec): Use Ffunctionp.
20372 * fns.c (concat, mapcar1): Accept byte-code-functions.
20374 * eval.c (Fsetq): Handle lexical vars.
20375 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
20376 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
20377 (FletX, Flet): Obey lexical binding.
20378 (Fcommandp): Handle closures.
20379 (Feval): New `lexical' arg.
20380 (eval_sub): New function extracted from Feval. Use it almost
20381 everywhere where Feval was used. Look up vars in lexical env.
20383 (Ffunctionp): Move from subr.el.
20384 (Ffuncall): Handle closures.
20385 (apply_lambda): Remove `eval_flags'.
20386 (funcall_lambda): Handle closures and new byte-code-functions.
20387 (Fspecial_variable_p): New function.
20388 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
20389 but without exporting it to Lisp.
20391 * doc.c (Fdocumentation, store_function_docstring):
20392 * data.c (Finteractive_form): Handle closures.
20394 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
20397 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
20399 (exec_byte_code): New function extracted from Fbyte_code to handle new
20400 calling convention for byte-code-functions. Add new byte-codes.
20402 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
20404 * alloc.c (Fmake_symbol): Init new `declared_special' field.
20406 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20408 * xdisp.c (redisplay_internal): Fix prototype.
20410 2011-03-31 Eli Zaretskii <eliz@gnu.org>
20412 * xdisp.c (SCROLL_LIMIT): New macro.
20413 (try_scrolling): Use it when setting scroll_limit.
20414 Limit scrolling to 100 screen lines.
20415 (redisplay_window): Even when falling back on "recentering",
20416 position point in the window according to scroll-conservatively,
20417 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
20419 (try_scrolling): When point is above the window, allow searching
20420 as far as scroll_max, or one screenful, to compute vertical
20421 distance from PT to the scroll margin position. This prevents
20422 try_scrolling from unnecessarily failing when
20423 scroll-conservatively is set to a value slightly larger than the
20424 window height. Clean up the case of PT below the margin at bottom
20425 of window: scroll_max can no longer be INT_MAX. When aggressive
20426 scrolling is in use, don't let point enter the opposite scroll
20427 margin as result of the scroll.
20428 (syms_of_xdisp) <scroll-conservatively>: Document the
20429 threshold of 100 lines for never-recentering scrolling.
20431 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20433 * dispextern.h (move_it_by_lines):

20436 (message_log_check_duplicate): Remove parameters `prev_bol' and
20437 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
20438 (redisplay_internal): Remove parameter `preserve_echo_area',
20439 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
20441 * indent.c (Fvertical_motion):
20442 * window.c (window_scroll_pixel_based, Frecenter):
20443 Don't pass `need_y_p' to `move_it_by_lines'.
20445 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
20447 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
20448 steal a few bits to be more compact.
20449 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
20450 Remove unneeded casts.
20452 * bytecode.c (Fbyte_code): CAR and CDR can GC.
20454 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
20456 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
20457 binding" message (bug#7967).
20459 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
20461 Fix more problems found by GCC 4.6.0's static checks.
20463 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
20464 Remove unused local var.
20466 * editfns.c (Fmessage_box): Remove unused local var.
20468 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
20469 (note_mode_line_or_margin_highlight, note_mouse_highlight):
20470 Omit unused local vars.
20471 * window.c (shrink_windows): Omit unused local var.
20472 * menu.c (digest_single_submenu): Omit unused local var.
20473 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
20474 Omit unused local var.
20476 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
20477 Don't assume string length fits in int.
20478 (keyremap_step, read_key_sequence): Use size_t for sizes.
20479 (read_key_sequence): Don't check last_real_key_start redundantly.
20481 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
20482 instead of alloca (Bug#8344).
20484 * eval.c (Fbacktrace): Don't assume nargs fits in int.
20485 (Fbacktrace_frame): Don't assume nframes fits in int.
20487 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

20492 * term.c (produce_glyphless_glyph): Remove unnecessary test.
20494 * cm.c (calccost): Turn while-do into do-while, for clarity.
20496 * keyboard.c (syms_of_keyboard): Use the same style as later
20497 in this function when indexing through an array. This also
20498 works around GCC bug 48267.
20500 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
20502 * xselect.c (x_check_property_data): Return correct size (Bug#8335).

20505 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
20507 * keyboard.c, keyboard.h (num_input_events): Now size_t.
20508 This avoids undefined behavior on integer overflow, and is a bit
20509 more convenient anyway since it is compared to a size_t variable.
20511 Variadic C functions now count arguments with size_t, not int.
20512 This avoids an unnecessary limitation on 64-bit machines, which
20513 caused (substring ...) to crash on large vectors (Bug#8344).
20514 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
20515 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
20516 All variadic functions and their callers changed accordingly.

20521 (internal_condition_case_n, run_hook_with_args, apply_lambda)
20522 (funcall_lambda, mark_backtrace): Likewise.
20523 * fns.c (concat): Likewise.
20524 * frame.c (x_set_frame_parameters): Likewise.
20525 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
20526 0 if not found, not -1. All callers changed.
20528 * alloc.c (garbage_collect): Don't assume stack size fits in int.
20529 (stack_copy_size): Now size_t, not int.
20530 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

20536 All callers changed.
20538 * lisp.h (multibyte_char_to_unibyte):
20539 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
20540 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

20546 * xdisp.c (message_dolog, set_message_1): All callers changed.
20548 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
20550 * keyboard.c (safe_run_hook_funcall): New function.
20551 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
20552 don't set the hook to nil, but remove the offending function instead.
20553 (Qcommand_hook_internal): Remove, unused.
20554 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
20555 Vcommand_hook_internal.
20557 * eval.c (enum run_hooks_condition): Remove.
20558 (funcall_nil, funcall_not): New functions.
20559 (run_hook_with_args): Call each function through a `funcall' argument.
20560 Remove `cond' argument, now redundant.
20561 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
20562 (Frun_hook_with_args_until_failure): Adjust accordingly.
20563 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
20565 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
20567 * dispextern.h (string_buffer_position): Remove declaration.
20569 * print.c (strout): Remove parameter `multibyte', unused since
20570 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
20572 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
20573 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
20574 All callers changed.
20576 * w32.c (_wsa_errlist): Use braces for struct initializers.

20579 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
20580 All callers changed.

20582 used outside xdisp.c).
20583 (cursor_row_p): Remove parameter `w', unused since
20584 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

20586 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
20587 All callers changed.
20589 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
20591 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

20620 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
20622 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
20624 * w32.c (read_unc_volume): Use parameter `henum', instead of
20625 global variable `wget_enum_handle'.
20627 * keymap.c (describe_vector): Remove parameters `indices' and
20628 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

20643 * gtkutil.c (xg_maybe_add_timer):
20644 * keyboard.c (readable_events):
20645 * process.c (wait_reading_process_output):
20646 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
20648 * insdel.c (adjust_markers_gap_motion):
20649 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.

20725 * term.c (Fsuspend_tty, Fresume_tty):
20726 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
20727 * window.c (temp_output_buffer_show):

20732 * editfns.c (save_excursion_restore):
20733 * cmds.c (internal_self_insert):
20734 * callint.c (Fcall_interactively):
20735 * buffer.c (Fkill_all_local_variables):
20736 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
20738 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
20739 unconditionally since it does the check itself.
20741 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
20743 Fix more problems found by GCC 4.5.2's static checks.
20745 * coding.c (encode_coding_raw_text): Avoid unnecessary test
20746 the first time through the loop, since we know p0 < p1 then.
20747 This also avoids a gcc -Wstrict-overflow warning.
20749 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
20750 leading to a memory leak, possible in functions like
20751 load_charset_map_from_file that can allocate an unbounded number
20752 of objects (Bug#8318).
20754 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
20755 that could (at least in theory) be that large.
20757 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
20758 This is less likely to overflow, and avoids undefined behavior if
20759 overflow does occur. All callers changed. Use strtoul to scan
20760 for the unsigned long integer.
20761 (pint2hrstr): Simplify and tune code slightly.
20762 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

20772 * fileio.c (Fcopy_file): Report error if fchown or fchmod
20775 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
20777 * process.c (Fmake_network_process): Use socklen_t, not int,
20778 where POSIX says socklen_t is required in portable programs.
20779 This fixes a porting bug on hosts like 64-bit HP-UX, where
20780 socklen_t is wider than int (Bug#8277).
20781 (Fmake_network_process, server_accept_connection):
20782 (wait_reading_process_output, read_process_output):
20785 * process.c: Rename or move locals to avoid shadowing.
20786 (list_processes_1, Fmake_network_process):
20787 (read_process_output_error_handler, exec_sentinel_error_handler):
20788 Rename or move locals.
20789 (Fmake_network_process): Define label "retry_connect" only if needed.
20790 (Fnetwork_interface_info): Fix pointer signedness.

20792 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
20793 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
20795 Make tparam.h and terminfo.c consistent.
20796 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
20797 Include tparam.h instead, since it declares them.
20798 * cm.h (PC): Remove extern decl; tparam.h now does this.
20799 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
20800 * terminfo.c: Include tparam.h, to check interfaces.
20801 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
20802 (tparam): Adjust signature to match interface in tparam.h;
20803 this removes some undefined behavior. Check that outstring and len
20804 are zero, which they always are with Emacs.
20805 * tparam.h (PC, BC, UP): New extern decls.
20807 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
20808 (xftfont_open): Rename locals to avoid shadowing.
20810 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
20811 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
20812 (OTF_TAG_SYM): Omit macro if not needed.
20813 (ftfont_list): Remove unused local.
20814 (get_adstyle_property, ftfont_pattern_entity):
20815 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
20816 Rename locals to avoid shadowing.
20818 * xfont.c (xfont_list_family): Mark var as initialized.
20820 * xml.c (make_dom): Now static.
20822 * composite.c (composition_compute_stop_pos): Rename local to
20824 (composition_reseat_it): Remove unused locals.
20825 (find_automatic_composition, composition_adjust_point): Likewise.
20826 (composition_update_it): Mark var as initialized.
20827 (find_automatic_composition): Mark vars as initialized,
20828 with a FIXME (Bug#8290).
20830 character.h: Rename locals to avoid shadowing.
20831 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
20832 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
20833 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
20834 (BUF_DEC_POS): Be more systematic about renaming local temporaries
20835 to avoid shadowing.
20837 * textprop.c (property_change_between_p): Remove; unused.
20839 * intervals.c (interval_start_pos): Now static.
20841 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
20843 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
20844 Rename locals to avoid shadowing.
20846 * sound.c (wav_play, au_play, Fplay_sound_internal):
20847 Fix pointer signedness.
20848 (alsa_choose_format): Remove unused local var.
20849 (wav_play): Initialize a variable to 0, to prevent undefined
20850 behavior (Bug#8278).
20852 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
20854 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
20856 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
20857 clobbering (Bug#8298).
20858 * sysdep.c (sys_subshell): Likewise.
20859 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
20861 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
20862 This should get cleaned up, so that child_setup has the
20863 same signature on all platforms.
20865 * callproc.c (call_process_cleanup): Now static.
20866 (relocate_fd): Rename locals to avoid shadowing.
20868 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
20870 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
20871 not to be necessary, and produces flickering.
20873 2011-03-20 Glenn Morris <rgm@gnu.org>
20875 * config.in: Remove file.
20877 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
20879 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
20880 are now in src/globals.h.
20881 (syms_of_minibuf): Remove spurious & from previous change.

21035 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21036 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
21037 to use the following functions instead of these macros.
21038 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
21039 EMACS_INT, since callers assume the returned value fits in int.
21040 (upcase1): Likewise, for UPCASE_TABLE.
21041 (uppercasep, lowercasep, upcase): New static inline functions.
21042 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

21052 (regex_compile, re_match_2_internal): Mark locals as initialized.
21053 (RETALLOC_IF): Define only if needed.
21054 (WORDCHAR_P): Likewise. This one is never needed, but is used
21055 only in a comment talking about a compiler bug, so put inside
21056 the #if 0 of that comment.
21057 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
21058 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

21084 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
21085 New macros, so that the caller can use some names other than
21086 gcpro1, gcpro2, etc.
21087 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
21089 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
21090 argument, for consistency with GCPRO2_VAR, etc: it is now the
21091 prefix of the variable, not the variable itself. All uses
21093 * dired.c (directory_files_internal, file_name_completion):
21094 Rename locals to avoid shadowing.
21096 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
21097 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
21098 dired.c's scmp function, had undefined behavior.
21099 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21100 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
21101 * buffer.h: ... to here, because these macros use current_buffer,
21102 and the new implementation with inline functions needs to have
21103 current_buffer in scope now, rather than later when the macros
21105 (downcase, upcase1): New static inline functions.
21106 (DOWNCASE, UPCASE1): Reimplement using these functions.
21107 This avoids undefined behavior in expressions like
21108 DOWNCASE (x) == DOWNCASE (y), which previously suffered
21109 from race conditions in accessing the global variables
21110 case_temp1 and case_temp2.
21111 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
21112 * lisp.h (case_temp1, case_temp2): Remove their decls.
21113 * character.h (ASCII_CHAR_P): Move from here ...
21114 * lisp.h: ... to here, so that the inline functions mentioned
21115 above can use them.
21117 * dired.c (directory_files_internal_unwind): Now static.
21119 * fileio.c (file_name_as_directory, directory_file_name):
21120 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
21122 (file_name_as_directory): Use const pointers when appropriate.
21123 (Fexpand_file_name): Likewise. In particular, newdir might
21124 point at constant storage, so make it a const pointer.
21125 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
21126 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
21128 (Fset_file_times, Finsert_file_contents, auto_save_error):

21133 to avoid shadowing.
21135 * marker.c (bytepos_to_charpos): Remove; unused.
21137 * lisp.h (verify_bytepos, count_markers): New decls,
21138 so that gcc does not warn that these functions aren't declared.
21140 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
21141 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
21142 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
21143 (copy_text): Remove unused local var.
21145 * filelock.c (within_one_second): Now static.
21146 (lock_file_1): Rename local to avoid shadowing.
21148 * buffer.c (fix_overlays_before): Mark locals as initialized.
21149 (fix_start_end_in_overlays): Likewise. This function should be
21150 simplified by using pointers-to-pointers, but that's a different
21152 (switch_to_buffer_1): Now static.
21153 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
21154 (report_overlay_modification): Rename locals to avoid shadowing.
21156 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
21157 Fix pointer signedness issue.
21158 (sys_subshell): Mark local as volatile if checking for lint,
21159 to suppress a gcc -Wclobbered warning that does not seem to be right.
21160 (MAXPATHLEN): Define only if needed.
21162 * process.c (serial_open, serial_configure): Move decls from here ...
21163 * systty.h: ... to here, so that they can be checked.
21165 * fns.c (get_random, seed_random): Move extern decls from here ...
21166 * lisp.h: ... to here, so that they can be checked.
21168 * sysdep.c (reset_io): Now static.
21169 (wait_for_termination_signal): Remove; unused.
21171 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
21172 (copy_keymap_item, append_key, push_text_char_description):
21174 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
21175 (DENSE_TABLE_SIZE): Remove; unused.
21176 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
21177 (describe_map_tree):
21178 Rename locals to avoid shadowing.
21180 * keyboard.c: Declare functions static if they are not used elsewhere.

21265 (BUF_PT_BYTE): Rewrite to handle indirect buffers (Bug#8219).
21266 These macros can no longer be used for assignment.

21328 1152921504606846976) returns the obviously-bogus value (-948597
21329 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
