8 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
10 Work around bug in CIFS and vboxsf file systems (Bug#13149).
11 The bug was observed on Ubuntu operating inside a virtual machine,
12 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
13 The workaround introduces a race condition on non-buggy hosts,
14 but it's an unlikely race and anyway there's a nearly identical
15 nearby race that can't be fixed.
16 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
18 (Fwrite_region): Test for file system time stamp bug.
19 (init_fileio): New function.

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

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

487 * buffer.h (BUF_COMPACT): New macro to follow the common style.
488 * buffer.c (Fget_buffer_create): Use it to set compact field of
489 struct buffer_text to avoid accessing an uninitialized value
490 when compact_buffer is called for the first time.
491 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
492 (Fset_buffer_modified_p): Use buffer_window_count to check
493 whether the buffer is displayed in some window.
494 * xdisp.c (message_dolog): Likewise.
496 2012-12-23 Eli Zaretskii <eliz@gnu.org>
498 * w32.c (acl_set_file): If setting the file security descriptor
499 fails, and the new DACL is identical to the existing one, silently
500 return success. This fixes problems for users backing up their
501 own files without having the necessary privileges for setting
502 security descriptors.
504 * w32proc.c (reader_thread): Do not index fd_info[] with negative
506 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
507 after WaitForSingleObject returns normally. This expedites reader
508 thread shutdown when delete_child triggers it.
509 (reap_subprocess): More accurate commentary for why we call
510 delete_child only when cp->fd is negative.
512 * w32.c (sys_close): Do not call delete_child on a subprocess
513 whose handle is not yet closed. Instead, set its file descriptor
514 to a negative value, so that reap_subprocess will call
515 delete_child on that subprocess when its SIGCHLD arrives.
516 This avoids closing handles used for communications between sys_select
517 and reader_thread, which doesn't give sys_select a chance to
518 notice that the process exited and invoke the SIGCHLD handler for
521 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
523 * nsfns.m (Fns_do_applescript): Run event loop until script has
524 been executed (Bug#12969).
525 (ns_run_ascript): Chech as_script for nil, set to nil after
528 2012-12-22 Martin Rudalics <rudalics@gmx.at>
530 * window.c (Fselect_window): Reword doc-string (Bug#13248).
532 2012-12-22 Eli Zaretskii <eliz@gnu.org>
534 * w32term.c (w32fullscreen_hook): New function.
535 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
537 2012-12-21 Eli Zaretskii <eliz@gnu.org>
539 * fileio.c (Finsert_file_contents): Doc fix.
541 * w32proc.c (new_child, delete_child, find_child_pid): For a
542 subprocess, consider its slot being in use as long as its process
543 handle (procinfo.hProcess) is not NULL. This avoids reusing the
544 slot when a new process is started immediately after killing
545 another one, without waiting enough time for the first process to
546 be reaped and resources allocated for it be orderly freed.
548 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
550 2012-12-21 Chong Yidong <cyd@gnu.org>
552 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
554 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
556 2012-12-21 Eli Zaretskii <eliz@gnu.org>
558 * w32.c (get_name_and_id): Always pass NULL as the first argument
559 of lookup_account_sid. Avoids crashes with UNC file names that
560 refer to DFS domains, not to specific machine names. (Bug#12621)
561 Remove now unused argument FNAME; all callers changed.
562 (get_file_owner_and_group): Remove now unused argument FNAME; all
565 2012-12-21 Chong Yidong <cyd@gnu.org>
567 * editfns.c (Finsert_char): Since read-char-by-name now signals an
568 error for invalid chars, don't check for a nil return value.
570 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
572 Avoid calls to CHAR_TO_BYTE if byte position is known.
573 * editfns.c (make_buffer_string_both): Use move_gap_both.
574 (Fbuffer_string): Use make_buffer_string_both.
575 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
577 (buf_bytepos_to_charpos): Likewise.
578 (charpos_to_bytepos): Remove.
579 * fileio.c (Finsert_file_contents): Use move_gap_both.
580 * search.c (Freplace_match): Likewise.
581 * process.c (process_send_region): Likewise. Use convenient
582 names for byte positions.
583 * lisp.h (charpos_to_bytepos): Remove prototype.
584 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
585 * insdel.c (move_gap): Likewise.
587 2012-12-20 Paul Eggert <eggert@cs.ucla.edu>
589 * xdisp.c (redisplay_internal): Remove now-unused local.
591 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
593 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
594 (redisplay_internal): Don't bother selecting the frame to get the
595 proper value of frame-local variables (bug#13225).
597 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
599 * textprop.c (set_text_properties_1): Do not allow NULL interval.
600 Rename 4th argument since it may be buffer or string. Adjust comment.
601 * intervals.c (graft_intervals_info_buffer): Find an interval here.
603 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
605 * coding.c (Fdetect_coding_region): Do not check start and end with
606 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
607 (code_convert_region): Likewise.
609 2012-12-18 Eli Zaretskii <eliz@gnu.org>
611 * w32.c (acl_get_file, acl_set_file): Run the file name through
612 map_w32_filename, and resolve any symlinks in the file name, like
614 (acl_set_file): Call revert_to_self, if any privileges were
617 2012-12-17 Juanma Barranquero <lekktu@gmail.com>

620 ($(BLD)/w32.$(O)): Update dependencies.
622 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
624 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
625 propagate redisplay's scrolling (if any) to the right window.
626 (redisplay_internal): Use ensure_selected_frame.
627 (display_mode_lines): Complete last fix.
628 * window.c (select_window_1): New func, extracted from select_window.
629 (select_window): Use it.
630 * window.h (select_window_1): Declare.
632 2012-12-17 Eli Zaretskii <eliz@gnu.org>
634 Emulate Posix ACL APIs on MS-Windows.
635 * w32.c: Include sddl.h and sys/acl.h.
636 (SDDL_REVISION_1): Define if not already defined.

654 * fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.
656 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
658 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
659 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
660 for some of that bug's symptoms can now cause Emacs to abort.
661 Remove the workaround.
662 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
663 The bug that caused SIGCHLD to get lost has been fixed, and the
664 workaround for it can now cause Emacs to abort.
666 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
668 * sysdep.c (emacs_abort): Bump backtrace size to 40.
669 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
670 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
672 2012-12-16 Romain Francoise <romain@orebokech.com>
674 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
675 (Fcopy_file): Change last arg to `preserve_extended_attributes'
676 and copy ACL entries of file in addition to SELinux context if set.
677 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
679 * Makefile.in (LIBACL_LIBS): New macro.
682 2012-12-15 Paul Eggert <eggert@cs.ucla.edu>
684 * fileio.c (internal_delete_file): Use bool for boolean.
686 2012-12-15 Eli Zaretskii <eliz@gnu.org>
688 Fix bug #13079 on MS-Windows with temp files not being deleted.

691 (register_child): First argument is now pid_t.
692 (record_infile, record_pending_deletion): New prototypes.
694 * w32proc.c (new_child): Initialize input_file and
695 pending_deletion members of the child.
696 (delete_child): Delete the child's temporary input file, if any,
697 that is pending deletion.
698 (register_child): First argument is now pid_t.
699 (record_infile, record_pending_deletion): New functions.
700 (reap_subprocess): Fix a typo in DebPrint string.
701 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
703 * fileio.c (internal_delete_file): Return an int again: non-zero
704 if delete-file succeeds, zero otherwise.
706 * lisp.h (internal_delete_file): Adjust prototype.
708 * callproc.c (Fcall_process): Don't overwrite infile with result
710 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
711 asynchronous subprocess, record the name of the input file name,
713 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
714 delete the file, record it as pending deletion when the subprocess
717 2012-12-14 Eli Zaretskii <eliz@gnu.org>
719 * editfns.c [HAVE_PWD_H]: Include grp.h.
721 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.
723 2012-12-14 Paul Eggert <eggert@cs.ucla.edu>
725 Fix permissions bugs with setgid directories etc. (Bug#13125)
726 * dired.c (Ffile_attributes): Return t as the 9th attribute,
727 to mark it as a placeholder. The old value was often wrong.
728 The only user of this attribute has been changed to use
729 file-ownership-preserved-p instead, with its new group arg.
730 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.

737 2012-12-14 Eli Zaretskii <eliz@gnu.org>
739 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
740 try to get accurate owner and group information from NT file
741 security APIs. This is to make most callers of 'stat' and
742 'lstat', which don't need that information, much faster.
744 * dired.c (Ffile_attributes) [WINDOWSNT]:
745 Set w32_stat_get_owner_group to a non-zero value, to request accurate
746 owner and group information from 'lstat'.
748 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
750 * fileio.c (Finsert_file_contents): Don't put tail into head area,
751 as that confuses set-auto-coding, so insist on the head-read
752 returning the full 1024 bytes. Let lseek compute the tail offset;
753 less work for us. Do not ignore I/O errors when reading the tail.
755 * xdisp.c: Minor style fixes.
756 (init_iterator): Hoist assignment out of if-expression.
757 (markpos_of_region): Callers now test for sign, not for -1.

774 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
776 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
777 files, fixing a regression from 24.2.
778 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
780 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
782 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
783 fstat shouldn't fail, and if it does fail copy-file should not proceed.
784 Remove unnecessary S_ISLNK test, as (contra the comments) this
785 function can't copy symlinks. Improve quality of error message
786 when attempting to copy files that are neither regular files nor
789 2012-12-12 Dmitry Antipov <dmantipov@yandex.ru>

797 2012-12-12 Daniel Colascione <dancol@dancol.org>
799 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
800 the dumped Emacs is not a sparse file, greatly improving Cygwin
801 "make bootstrap" performance.
803 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
805 * inotify.c (inotify_callback): Generate an Emacs event for every
806 incoming inotify event.
808 2012-12-11 Eli Zaretskii <eliz@gnu.org>
810 * xdisp.c (handle_face_prop): Fix logic of computing
811 it->start_of_box_run_p.
812 (append_space_for_newline): If the glyph row is R2L, reset the
813 iterator's end_of_box_run_p flag before prepending the space glyph.
814 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
815 iterator's start_of_box_run_p flag before prepending the stretch.
816 (append_glyph, produce_image_glyph, append_composite_glyph)
817 (append_stretch_glyph, append_glyphless_glyph): Reverse the
818 left_box_line_p and right_box_line_p flags of the glyph for R2L
819 glyph rows. (Bug#13011)
821 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
823 * buffer.c (Fset_buffer_multibyte): Do not force redisplay
824 if changed buffer is not shown in a window.

826 * window.c (replace_buffer_in_windows_safely): Do nothing
827 if buffer is not shown in a window.
828 (Fforce_window_update): Likewise if string or buffer argument
831 2012-12-11 Eli Zaretskii <eliz@gnu.org>
833 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
834 encoded_file_name, which is what it is.
836 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>

860 Windows file notification functionality unless WINDOWSNT.
862 * w32gui.h (hprevinst, lpCmdLine, nCmdShow): Remove unused
865 * w32fns.c (cache_system_info): Initialize the global hinst

868 * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused variables.
869 (hinst): Remove unneeded extern declaration.
870 (_start): Remove initialization of above variables; remove
871 initialization of hinst, as cache_system_info now does that.
873 * emacs.c (main): Call cache_system_info early in startup; we
874 previously weren't calling it in Cygwin builds.
876 * Makefile.in (ntsource, WINDRES, W32_RES, W#@_RES_LINK):

988 (GetProcessWorkingSetSize_Proc, get_process_working_set_size)
989 (system_process_attributes): Use SIZE_T rather than DWORD, for
990 compatibility with 64-bit builds.
992 2012-12-10 Christopher Schmidt <christopher@ch.ristopher.com>

996 2012-12-10 Eli Zaretskii <eliz@gnu.org>
998 * indent.c (Fvertical_motion): If a display string will be
999 displayed on the left or the right margin, don't consider it as a
1000 factor in cursor positioning. (Bug#13108)
1002 2012-12-10 Martin Rudalics <rudalics@gmx.at>
1004 * editfns.c (Fcompare_buffer_substrings): Reword doc-string.
1006 2012-12-10 Paul Eggert <eggert@cs.ucla.edu>

1011 2012-12-08 Eli Zaretskii <eliz@gnu.org>
1013 * w32.c (unsetenv): Return 0 if the input string is too long.
1015 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
1017 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).
1018 * alloc.c (xputenv): New function.
1019 * dbusbind.c (Fdbus_init_bus):
1021 * xterm.c (x_term_init):
1022 Use xputenv instead of setenv or putenv, to detect memory exhaustion.
1023 * editfns.c (initial_tz): Move static var decl up.
1024 (tzvalbuf_in_environ): New static var.
1025 (init_editfns): Initialize these two static vars.
1026 (Fencode_time): Don't assume arbitrary limit on EMACS_INT width.
1027 Save old TZ value on stack, if it's small.
1028 (Fencode_time, set_time_zone_rule): Don't modify 'environ' directly;
1029 instead, use xputenv+unsetenv to set and restore TZ.
1030 (environbuf): Remove static var. All uses removed.
1031 (Fset_time_zone_rule): Do not save TZ and environ;
1032 no longer needed here.
1033 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
1034 Move to inside set_time_zone_rule; they don't need file scope any more.
1035 (set_time_zone_rule): Maintain the TZ=value string separately.
1036 (syms_of_editfns): Don't initialize initial_tz;
1037 init_editfns now does it.
1038 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
1039 * lisp.h (xputenv): New decl.
1041 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
1043 * w32fns.c (emacs_abort): Don't do arithmetics on void pointers.
1045 2012-12-08 Eli Zaretskii <eliz@gnu.org>
1047 * w32.c (unsetenv, sys_putenv): New functions.
1049 2012-12-08 Chong Yidong <cyd@gnu.org>
1051 * editfns.c (Finsert_char): Make the error message more
1052 informative (Bug#12992).
1054 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
1056 Simplify get_lim_data.
1057 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
1058 Remove USG and vlimit methods; no longer used these days.
1059 Add #error catchall just in case.
1061 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
1062 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
1063 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
1064 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
1065 (deleted_pid_list, Fdelete_process, create_process)
1066 (record_child_status_change, handle_child_signal, deliver_child_signal)
1067 (init_process_emacs, syms_of_process):
1068 Assume SIGCHLD is defined.
1069 (parse_signal): Remove. All uses removed.
1070 (abbr_to_signal): New static function.
1071 (Fsignal_process): Use it to convert signal names to ints.
1072 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
1073 kill (getpgrp (), ...).
1074 (emacs_sigaction_init): Assume SIGCHLD is defined.
1075 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,
1076 SIGPIPE, and SIGQUIT are defined. Do not worry about SIGCLD any more.
1077 * syssignal.h (EMACS_KILLPG): Remove.
1078 All uses replaced by 'kill' with a negative pid.
1079 (SIGCHLD): Remove definition, as we now assume SIGCHLD.
1080 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
1082 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
1084 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
1085 This will cause a production Emacs to dump core instead of
1088 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1090 * frame.c (make_frame): Do not set window's buffer to t.
1091 * window.c (Fsplit_window_internal): Likewise. Previously it was
1092 used to indicate that the window is being set up. Now we use
1093 set_window_buffer for all new windows, so the condition in ...
1094 (Fset_window_buffer): ... is always true and can be removed.
1096 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1098 Convenient macro to check whether the buffer is hidden.
1099 * buffer.h (BUFFER_HIDDEN_P): New macro.
1100 * frame.c (make_frame): Use it. Adjust comment.
1101 * buffer.c (candidate_buffer): New function.
1102 (Fother_buffer, other_buffer_safely): Use it.
1104 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1106 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
1107 if the child process is still running. Instead, exit the wait
1108 loop and return zero. (Bug#13086)
1110 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1112 * frame.h (x_char_width, x_char_height): Remove prototypes.
1113 * w32term.h (x_char_width, x_char_height): Likewise.
1114 * xfns.c (x_char_width, x_char_height): Remove.

1123 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
1125 Fix a recently-introduced delete-process race condition.
1126 * callproc.c, process.h (record_kill_process):
1127 New function, containing part of the old call_process_kill.
1128 (call_process_kill): Use it.
1129 This does not change call_process_kill's behavior.
1130 * process.c (Fdelete_process): Use record_kill_process to fix a
1131 race condition that could cause Emacs to lose track of a child.
1133 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1135 Avoid code duplication between prev_frame and next_frame.
1136 * frame.c (candidate_frame): New function. Add comment.
1137 (prev_frame, next_frame): Use it. Adjust comment.
1139 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1141 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
1142 fails, signal an error instead of continuing with an empty
1144 Encode expanded temp file pattern before passing it to mkstemp or
1147 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
1148 Encode the file name before passing it to dostounix_filename, in
1149 case it will downcase it (under w32-downcase-file-names).
1152 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
1154 Minor call-process cleanups.
1155 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
1156 at the same time as other platforms, to simplify analysis.
1157 No need for fd0_volatile since we have synch_process_fd.
1158 Avoid needless emacs_close; arg is always negative.
1160 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
1162 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
1165 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
1167 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
1168 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
1169 and mouse_face_hidden members to a bitfields.
1170 * frame.h (struct frame): Remove set-but-not-used space_width member.
1171 (FRAME_SPACE_WIDTH): Remove.
1172 * nsterm.m, w32term.c, xterm.c: Adjust users.
1173 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
1174 member. Adjust users. Convert term_initted, delete_in_insert_mode,
1175 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
1176 members to a bitfields.
1178 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
1180 Don't let call-process be a zombie factory (Bug#12980).
1181 Fixing this bug required some cleanup of the signal-handling code.
1182 As a side effect, this change also fixes a longstanding rare race
1183 condition whereby Emacs could mistakenly kill unrelated processes,
1184 and it fixes a bug where a second C-g does not kill a recalcitrant
1185 synchronous process in GNU/Linux and similar platforms.
1186 The patch should also fix the last vestiges of Bug#9488,
1187 a bug which has mostly been fixed on the trunk by other changes.
1188 * callproc.c, process.h (synch_process_alive, synch_process_death)
1189 (synch_process_termsig, sync_process_retcode):
1190 Remove. All uses removed, to simplify analysis and so that
1191 less consing is done inside critical sections.
1192 * callproc.c (call_process_exited): Remove. All uses replaced
1193 with !synch_process_pid.
1194 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
1195 These take the role of what used to be in unwind-protect arg.
1197 (block_child_signal, unblock_child_signal):
1198 New functions, to avoid races that could kill innocent-victim processes.
1199 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
1200 (call_process_kill): Record killed processes as deleted, so that
1201 zombies do not clutter up the system. Do this inside a critical
1202 section, to avoid a race that would allow the clutter.
1203 (call_process_cleanup): Fix code so that the second C-g works again
1204 on common platforms such as GNU/Linux.
1205 (Fcall_process): Create the child process in a critical section,
1206 to fix a race condition. If creating an asynchronous process,
1207 record it as deleted so that zombies do not clutter up the system.
1208 Do unwind-protect for WINDOWSNT too, as that's simpler in the
1209 light of these changes. Omit unnecessary call to emacs_close
1210 before failure, as the unwind-protect code does that.
1211 * callproc.c (call_process_cleanup):
1212 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
1213 * process.c (record_deleted_pid): New function, containing
1214 code refactored out of Fdelete_process.
1215 (Fdelete_process): Use it.
1216 (process_status_retrieved): Remove. All callers changed to use
1217 child_status_change.
1218 (record_child_status_change): Remove, folding its contents into ...
1219 (handle_child_signal): ... this signal handler. Now, this
1220 function is purely a handler for SIGCHLD, and is not called after
1221 a synchronous waitpid returns; the synchronous code is moved to
1222 wait_for_termination. There is no need to worry about reaping
1223 more than one child now.
1224 * sysdep.c (get_child_status, child_status_changed): New functions.
1225 (wait_for_termination): Now takes int * status and bool
1226 interruptible arguments, too. Do not record child status change;
1227 that's now the caller's responsibility. All callers changed.
1228 Reimplement in terms of get_child_status.
1229 (wait_for_termination_1, interruptible_wait_for_termination):
1230 Remove. All callers changed to use wait_for_termination.
1231 * syswait.h: Include <stdbool.h>, for bool.
1232 (record_child_status_change, interruptible_wait_for_termination):
1234 (record_deleted_pid, child_status_changed): New decls.
1235 (wait_for_termination): Adjust to API changes noted above.
1237 * bytecode.c, lisp.h (Qbytecode): Remove.
1238 No longer needed after 2012-11-20 interactive-p changes.
1240 2012-12-03 Eli Zaretskii <eliz@gnu.org>
1242 * xdisp.c (redisplay_window): If the cursor is visible, but inside
1243 the scroll margin, move point outside the margin. (Bug#13055)
1245 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
1247 * gtkutil.c (my_log_handler): New function.
1248 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
1250 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1252 * lisp.h (modify_region): Rename to...
1253 (modify_region_1): ...new prototype.
1254 * textprop.c (modify_region): Now static. Adjust users.
1255 * insdel.c (modify_region): Rename to...
1256 (modify_region_1): ...new function to work with current buffer.
1257 Adjust comment and users. Use true and false for booleans.
1259 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1261 * alloc.c (free_save_value): New function.
1262 (safe_alloca_unwind): Use it.
1263 * lisp.h (free_save_value): New prototype.
1264 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
1266 (save_excursion_restore): Adjust to match saved data structure.
1267 Use free_save_value to offload some work from GC. Drop obsolete
1270 2012-12-03 Chong Yidong <cyd@gnu.org>
1272 * fileio.c (Vauto_save_list_file_name): Doc fix.
1274 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
1276 * w32fns.c: Remove prototype of atof.
1277 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
1279 (file_dialog_callback): Make it UINT_PTR.
1281 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
1284 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1285 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
1288 2012-12-03 Glenn Morris <rgm@gnu.org>
1290 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
1292 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
1294 Fix xpalloc confusion after memory is exhausted.
1295 * alloc.c (xpalloc): Comment fix.
1296 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
1297 and signals an error, do not clear charset_table_size, as
1298 charset_table is still valid.
1299 * doprnt.c (evxprintf): Clear *BUF after freeing it.
1301 Use execve to avoid need to munge environ (Bug#13054).
1302 * callproc.c (Fcall_process):
1303 * process.c (create_process):
1304 Don't save and restore environ; no longer needed.
1305 * callproc.c (child_setup):
1306 Use execve, not execvp, to preserve environ.
1308 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
1310 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
1312 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1314 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
1315 display for sliced images (Bug#10500).
1317 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
1319 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
1321 * doc.c (Fdocumentation): Re-add handling of function-documentation,
1322 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
1324 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
1326 * xdisp.c (window_outdated): Remove eassert since it hits
1327 some suspicious corner cases (see Bug#13007 and Bug#13012).
1328 (mode_line_update_needed): New function.
1329 (redisplay_internal, redisplay_window): Use it.
1330 (ensure_selected_frame): New function.
1331 (redisplay_internal, unwind_redisplay): Use it.
1332 (redisplay_internal): Move comment about buffer_shared...
1333 (buffer_shared_and_changed): ...near to its real use.
1335 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
1337 * callproc.c (Fcall_process): Don't misreport vfork failure.
1339 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
1341 * callproc.c (Fcall_process): Fix vfork portability problems.
1342 Do not assume that fd[0], count, filefd, and save_environ survive
1343 vfork. Fix bug whereby wrong errno value could be reported for
1344 pipe failure. Some minor cleanups, too, as follows. Move buf and
1345 bufsize to the context where they're needed. Change new_argv to
1346 be of type char **, as this is more convenient and avoids casts.
1347 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
1348 Now local constants, not macros.
1350 2012-11-18 Kenichi Handa <handa@gnu.org>
1352 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
1353 for the variable "f".
1355 2012-11-13 Kenichi Handa <handa@gnu.org>
1357 * font.c (font_unparse_xlfd): Exclude special characters from the
1358 generating XLFD name.
1360 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
1362 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.

1364 * fileio.c (Fexpand_file_name): Remove no-longer-needed casts.
1366 Assume POSIX 1003.1-1988 or later for errno.h (Bug#12968).

1368 Assume EAGAIN and EINTR are defined.
1370 * fileio.c (Fcopy_file): Assume EISDIR is defined.
1371 * gmalloc.c (ENOMEM, EINVAL): Assume they're defined.
1372 * gnutls.c (emacs_gnutls_write): Assume EAGAIN is defined.
1373 * lread.c (readbyte_from_file): Assume EINTR is defined.
1374 * process.c (wait_reading_process_output, send_process) [subprocesses]:
1375 Assume EIO and EAGAIN are defined.
1376 * unexcoff.c (write_segment): Assume EFAULT is defined.
1378 2012-11-27 Eli Zaretskii <eliz@gnu.org>
1380 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
1383 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
1384 highlighting on the frame was cleared. Prevents assertion
1385 violations when repeatedly clicking on the "Top" link of the
1386 "bread-crumbs" in Info buffers.
1388 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>
1390 * sysdep.c (sys_subshell): Don't assume pid_t fits in int.
1392 2012-11-24 Ken Brown <kbrown@cornell.edu>
1394 * keyboard.c (HAVE_MOUSE):
1395 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
1396 were always defined.
1398 2012-11-24 Eli Zaretskii <eliz@gnu.org>
1400 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
1401 between bpos_covered and bpos_max. This fixes cursor display when
1402 several display strings follow each other.
1404 * .gdbinit (pgx): If the glyph's object is a string, display the
1405 pointer to string data, rather than the value of the string object
1406 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
1408 * indent.c (Fvertical_motion): If the starting position is covered
1409 by a display string, return to one position before that, to avoid
1410 overshooting it inside move_it_to. (Bug#12930)
1412 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
1414 * frame.h (struct frame): Remove display_preempted member
1415 since all users are dead long ago.

1417 * w32menu.c (pending_menu_activation): Remove since not
1419 (set_frame_menubar): Adjust user.
1420 * w32term.h (struct x_output): Drop outdated #if 0 code.
1421 (struct w32_output): Use bitfields for explicit_parent,
1422 asked_for_visible and menubar_active members.
1423 Drop unused pending_menu_activation member.
1424 * xterm.h (struct x_output): Drop outdated #if 0 code.
1425 Use bitfields for explicit_parent, asked_for_visible,
1426 has_been_visible and net_wm_state_hidden_seen members.
1428 2012-11-23 Eli Zaretskii <eliz@gnu.org>
1430 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
1431 of a literal "/". (Bug#12955)
1432 (gl-stamp): Invoke fc.exe directly, not through cmd.
1434 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
1436 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
1437 * dired.c: Assume HAVE_DIRENT_H.
1438 (NAMLEN): Remove, replacing with ...
1439 (dirent_namelen): New function. All uses changed. Use the GNU macro
1440 _D_EXACT_NAMELEN if available, as it's faster than strlen.
1441 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
1442 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
1443 * makefile.w32-in (DIR_H): Remove. All uses replaced with
1445 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
1446 * ndir.h: Rename to ../nt/inc/dirent.h.
1447 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
1448 Do not include <dirent.h>; no longer needed.
1449 * w32.c: Include <dirent.h> rather than "ndir.h".
1451 2012-11-23 Chong Yidong <cyd@gnu.org>
1453 * xftfont.c (xftfont_open): Remove duplicate assignment.
1455 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
1457 * alloc.c (Fgarbage_collect): Unblock input after clearing
1458 gc_in_progress to avoid note_mouse_highlight glitch with GC.
1459 * frame.h (FRAME_MOUSE_UPDATE): New macro.
1460 * msdos.c (IT_frame_up_to_date): Use it here...
1461 * w32term.c (w32_frame_up_to_date): ...here...
1462 * xterm.c (XTframe_up_to_date): ...and here...
1463 * nsterm.m (ns_frame_up_to_date): ...but not here.
1464 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
1466 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
1467 Do not check whether GC is in progress.
1469 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
1471 * xdisp.c (window_buffer_changed): New function.
1472 (update_menu_bar, update_tool_bar): Use it to
1473 simplify large 'if' statements.
1474 (redisplay_internal): Generalize commonly used
1475 'tail' and 'frame' local variables.
1477 2012-11-22 Eli Zaretskii <eliz@gnu.org>
1479 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
1480 with Windows system header.
1482 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
1484 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
1485 * alloc.c: Assume unistd.h exists.
1486 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
1487 * sysdep.c (get_current_dir_name): Assume getcwd exists.
1488 (getwd) [USG]: Remove; no longer needed.
1489 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
1490 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
1491 * w32.h (getcwd): Remove decl.
1493 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
1495 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
1496 Make it set selected_window as well.
1497 (update_tool_bar): Use it.
1499 2012-11-21 Ken Brown <kbrown@cornell.edu>
1501 * emacs.c (main): Set the G_SLICE environment variable for all
1502 Cygwin builds, not just GTK builds. See
1503 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
1505 2012-11-21 Eli Zaretskii <eliz@gnu.org>
1507 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1508 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
1509 Define for the MSVC compiler.
1511 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
1513 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
1514 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
1515 dostounix_filename. Prevents crashes down the road, because
1516 dostounix_filename assumes it gets a unibyte string.
1517 Reported by Michel de Ruiter <michel@sentient.nl>, see
1518 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
1520 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>

1524 * lread.c (init_obarray): Set `function' fields to Qnil.
1525 * eval.c (Fcommandp): Ignore Qunbound.
1526 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
1527 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
1528 Test NILP rather than Qunbound.
1529 (Ffmakunbound): Set to Qnil.
1530 (Fsymbol_function): Never signal an error.
1531 (Finteractive_form): Ignore Qunbound.
1533 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
1535 * eval.c (interactive_p): Remove no-longer-used decl.
1537 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
1539 * xdisp.c (buffer_shared): Adjust comment.
1540 (buffer_shared_and_changed): New function.
1541 (prepare_menu_bars, redisplay_internal): Use it to
1542 decide whether all windows or frames should be updated.
1543 (window_outdated): New function.
1544 (text_outside_line_unchanged_p, redisplay_window): Use it.
1545 (redisplay_internal): Likewise. Fix indentation.
1547 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
1549 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
1550 (syms_of_eval): Remove corresponding defsubr.
1551 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
1553 2012-11-19 Daniel Colascione <dancol@dancol.org>
1555 * w32fns.c (Fx_file_dialog):
1556 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
1557 cygwin_convert_file_name*.
1559 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
1560 Rename cygwin_convert_path* to cygwin_convert_file_name*.
1562 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
1564 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
1566 2012-11-18 Eli Zaretskii <eliz@gnu.org>
1568 * w32select.c: Include w32common.h before w32term.h, so that
1569 windows.h gets included before w32term.h uses some of its
1570 features, see below.
1572 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
1574 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
1576 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
1578 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
1580 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
1581 (ns_select): Return at once if events are held (Bug#12834).
1583 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
1585 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
1586 Needed following 2012-10-20 change. (Bug#12902)
1588 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
1590 * w32proc.c (waitpid): Remove unused label get_result.
1592 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
1594 * makefile.w32-in (SYSWAIT_H): New macro.
1595 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
1596 ($(BLD)/sysdep.$(O)): Update dependencies.
1598 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
1600 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
1601 * callproc.c (relocate_fd): Assume F_DUPFD.
1602 * emacs.c, term.c (O_RDWR): Remove.
1603 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
1604 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
1605 * nsterm.m: Assume <fcntl.h> exists.
1606 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
1607 (create_pty, Fmake_network_process, server_accept_connection)
1608 (wait_reading_process_output, init_process_emacs):
1610 (wait_reading_process_output): Put in a special case for WINDOWSNT
1611 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
1612 It's not clear this is needed, but it's a more-conservative change.
1613 (create_process): Assume FD_CLOEXEC.
1614 (create_process, create_pty): Assume O_NOCTTY.
1615 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
1616 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
1617 Omit if not DOS_NT, since F_GETFL is not defined there.
1618 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
1619 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
1621 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
1622 lack it, since gnulib guarantees this.
1623 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
1625 2012-11-17 Eli Zaretskii <eliz@gnu.org>
1627 * w32.c (faccessat): Pretend that directories have the execute bit
1628 set. Emacs expects that, e.g., in files.el:cd-absolute.
1630 * w32proc.c (create_child): Don't clip the PID of the child
1631 process to fit into an Emacs integer, as this is no longer a
1633 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
1634 reaping only the process specified by PID argument, if that is
1635 positive. Use PID instead of dead_child to know which process to
1636 reap. Wait for the child to die only if WNOHANG is not in
1638 (sys_select): Don't set dead_child.
1640 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
1641 as it is no longer needed.
1643 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
1645 (record_child_status_change): Remove the setting of
1646 record_at_most_one_child for the !WNOHANG case.
1648 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
1650 Fix problems in ns port found by static checking.
1651 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
1652 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
1653 not to process group.
1654 (ns_select): Use emacs_write, not write, as that's more robust
1655 in the presence of signals.
1656 (fd_handler:): Check for read errors.
1658 2012-11-16 Glenn Morris <rgm@gnu.org>
1660 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
1662 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
1664 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
1666 2012-11-16 Eli Zaretskii <eliz@gnu.org>
1668 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
1669 use the same value of thread handle.
1670 (start_timer_thread): If the timer thread exited (due to error),
1671 clean up by closing the two handles it used. Duplicate the caller
1672 thread's handle here, so it gets duplicated only once, when
1673 launching the timer thread. Set priority of the timer thread, not
1675 (getitimer): Don't duplicate the caller thread's handle here.
1678 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
1680 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
1683 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
1685 Remove no-longer-used pty_max_bytes variable.
1686 * process.c (pty_max_bytes): Remove; unused.
1687 (send_process): Do not set it.
1689 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
1691 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
1692 Update dependencies.
1694 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
1696 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
1697 This follows up on the 2012-09-29 patch that removed indirection
1698 for the 'function' field. Reported by Sergey Vinokurov in
1699 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
1701 2012-11-14 Eli Zaretskii <eliz@gnu.org>
1703 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
1704 different name, as the MS runtime does not have such a function,
1705 and probably never will.) All callers changed. Ignore DIRFD
1706 value if PATH is an absolute file name, to match Posix spec
1707 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
1710 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
1712 * xdisp.c (echo_area_display, redisplay_internal):
1713 Omit redundant check whether frame_garbaged is set.
1715 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
1717 Use faccessat, not access, when checking file permissions (Bug#12632).
1718 This fixes a bug that has been present in Emacs since its creation.
1719 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
1720 which must set some sort of record. (Torek's bug report was against
1721 a predecessor of GNU Emacs, but GNU Emacs happened to have the
1722 same common flaw.) See Torek's Usenet posting
1723 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
1724 Posted: Fri Apr 8 14:18:56 1983.
1725 * Makefile.in (LIB_EACCESS): New macro.
1727 * callproc.c (init_callproc):
1728 * charset.c (init_charset):
1729 * fileio.c (check_existing, check_executable, check_writable)
1731 * lread.c (openp, load_path_check):
1732 * process.c (allocate_pty):
1734 Use effective UID when checking permissions, not real UID.
1735 * callproc.c (init_callproc):
1736 * charset.c (init_charset):
1737 * lread.c (load_path_check, init_lread):
1738 Test whether directories are accessible, not merely whether they exist.
1739 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
1740 * fileio.c (check_existing, check_executable, check_writable)
1742 Use symbolic names instead of integers for the flags, as they're
1744 (check_writable): New arg AMODE. All uses changed.
1745 Set errno on failure.
1746 (Ffile_readable_p): Use faccessat, not stat + open + close.
1747 (Ffile_writable_p): No need to call check_existing + check_writable.
1748 Just call check_writable and then look at errno. This saves a syscall.
1749 dir should never be nil; replace an unnecessary runtime check
1750 with an eassert. When checking the parent directory of a nonexistent
1751 file, check that the directory is searchable as well as writable, as
1752 we can't create files in unsearchable directories.
1753 (file_directory_p): New function, which uses 'stat' on most platforms
1754 but faccessat with D_OK (for efficiency) if WINDOWSNT.
1755 (Ffile_directory_p, Fset_file_times): Use it.
1756 (file_accessible_directory_p): New function, which uses a single
1757 syscall for efficiency.
1758 (Ffile_accessible_directory_p): Use it.
1759 * xrdb.c (file_p): Use file_directory_p.
1760 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
1761 * lread.c (openp): When opening a file, use fstat rather than
1762 stat, as that avoids a permissions race. When not opening a file,
1763 use file_directory_p rather than stat.
1764 (dir_warning): First arg is now a usage string, not a format.
1765 Use errno. All uses changed.
1766 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
1767 that merely introduced a race.
1768 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
1769 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
1770 and similarly for the other O_* flags.
1771 * w32.c (sys_faccessat): Rename from sys_access and switch to
1772 faccessat's API. All uses changed.
1773 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
1774 (magic_db): Rename from magic_file_p.
1775 (magic_db, search_magic_path): Return an XrmDatabase rather than a
1776 char *, so that we don't have to test for file existence
1777 separately from opening the file for reading. This removes a race
1778 fixes a permission-checking problem, and simplifies the code.
1780 (file_p): Remove; no longer needed.
1782 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
1784 Omit glyphs initialization at startup.
1785 * dispnew.c (glyphs_initialized_initially_p): Remove.
1786 (adjust_frame_glyphs_initially): Likewise. Adjust users.
1787 (Fredraw_frame): Move actual code from here...
1788 (redraw_frame): ...to here. Add eassert. Adjust comment.
1789 (Fredraw_display): Use redraw_frame.
1790 * xdisp.c (clear_garbaged_frames): Likewise.
1792 2012-11-13 Eli Zaretskii <eliz@gnu.org>
1794 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
1795 passed to pint2str and pint2hrstr to be at most the size of the
1796 frame's decode_mode_spec_buffer. This avoids crashes with very
1797 large values of FIELD_WIDTH argument to decode_mode_spec.
1800 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
1802 Fix a race with verify-visited-file-modtime (Bug#12863).
1803 Since at least 1991 Emacs has ignored an mtime difference of no
1804 more than one second, but my guess is that this was to work around
1805 file system bugs that were fixed long ago. Since the race is
1806 causing problems now, let's remove that code.
1807 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
1808 whose time stamp is off by no more than a second. Insist that the
1809 file time stamps match exactly.
1811 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1813 * frame.h (struct frame): Convert external_tool_bar member to
1814 1-bit unsigned bitfield.
1815 * termhooks.h (struct terminal): Remove mouse_moved member since
1816 all users are long dead. Adjust comment on mouse_position_hook.
1818 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1820 Simplify by using FOR_EACH_FRAME here and there.
1821 * frame.c (next_frame, prev_frame, other_visible_frames)
1822 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
1823 * w32term.c (x_window_to_scroll_bar): Likewise.
1824 * window.c (window_list): Likewise.
1825 * xdisp.c (x_consider_frame_title): Likewise.
1826 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
1827 * xfns.c (x_window_to_frame, x_any_window_to_frame)
1828 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
1829 * xmenu.c (menubar_id_to_frame): Likewise.
1830 * xselect.c (frame_for_x_selection): Likewise.
1831 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
1832 (x_window_to_menu_bar): Likewise.
1833 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
1835 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
1837 * data.c (Qdefalias_fset_function): Now static.
1839 Another tweak to vectorlike_header change.
1840 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
1841 Remove, and replace all uses with ...
1842 (next_in_free_list, set_next_in_free_list):
1843 New functions, which respect C's aliasing rules better.
1845 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
1847 * window.c (list4i): Rename from 'quad'. All uses changed.
1848 Needed because <sys/types.h> defines 'quad' on Solaris 10.
1850 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
1852 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
1853 warning about mixing declarations and code in ISO C90.
1855 2012-11-10 Martin Rudalics <rudalics@gmx.at>
1857 * window.c (Fsplit_window_internal): Set combination limit of
1858 new parent window to t iff Vwindow_combination_limit is t;
1859 fixing a regression introduced with the change from 2012-09-22.
1860 (Fset_window_combination_limit): Fix doc-string.
1862 2012-11-10 Eli Zaretskii <eliz@gnu.org>
1864 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
1865 amount when the scroll margins are too large. When scrolling
1866 backwards in the buffer, give up if cannot reach point or the
1867 scroll margin within a reasonable number of screen lines.
1868 Fixes point position in window under scroll-up/down-aggressively when
1869 point is positioned many lines beyond the window top/bottom.
1872 * ralloc.c (relinquish): If real_morecore fails to return memory
1873 to the system, don't crash; instead, leave the last heap
1874 unchanged and return. (Bug#12774)
1876 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1878 * lisp.h (AUTOLOADP): New macro.
1879 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
1880 * data.c (Ffset): Remove special ad-advice-info handling.
1881 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
1883 (Finteractive_form): Simplify.
1884 (Fquo): Don't insist on having at least 2 arguments.
1885 (Qdefalias_fset_function): New var.
1887 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1889 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
1891 * nsfont.m (Qcondensed, Qexpanded): New variables.
1892 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
1893 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.

1904 Tweak last vectorlike_header change.
1905 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
1906 vectorlike object on the free list. This is introduced to avoid
1907 some (but not all) pointer casting and aliasing problems, see
1908 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
1909 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike

1941 special hash function containing a comparison that always yields 1.
1943 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1945 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
1946 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
1947 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
1950 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
1952 * image.c (xpm_make_color_table_h): Fix compiler error because
1953 make_hash_table changed.
1955 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
1957 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
1959 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1961 Use ad-hoc comparison function for the profiler's hash-tables.
1962 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
1963 (make_log): Use them.
1964 (handle_profiler_signal): Don't inhibit quit any longer since we don't
1965 call Fequal any more.

1974 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
1975 (hash_lookup, hash_remove_from_table): Move assertion checking of
1976 hashfn result here. Check hash-equality before calling cmpfn.

1989 value of w32-scroll-lock-modifier is neither nil nor one of the
1990 known key modifiers. (Bug#12806)
1992 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
1994 Shrink struct vectorlike_header to the only size field.
1995 * lisp.h (enum pvec_type): Avoid explicit enum member values.
1997 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
1998 PVEC_TYPE_MASK to arrange new bitfield in the vector header.

2000 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
2001 information from the vector header. Adjust comment.

2023 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
2024 Add easserts. Adjust XSETPVECTYPESIZE usage.
2025 (allocate_buffer): Use BUFFER_PVEC_INIT.
2026 (live_vector_p): Adjust to match large vector.
2027 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
2028 * buffer.h (struct buffer): Add next member.

2039 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2041 * keyboard.c (event_to_kboard): Do not dereference
2042 frame_or_window field of SELECTION_REQUEST_EVENT
2043 and SELECTION_CLEAR_EVENT events (Bug#12814).
2044 * xterm.h (struct selection_input_event): Adjust comment.
2046 2012-11-07 Eli Zaretskii <eliz@gnu.org>
2048 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
2049 such as Scroll Lock, if the respective keys are treated as
2050 function keys, not as modifiers. This avoids destroying non-ASCII
2051 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
2053 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
2055 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
2057 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2059 Restore some duplicate definitions (Bug#12814).
2060 This undoes part of the 2012-11-03 changes. Some people build
2061 with plain -g rather than with -g3, and they need the duplicate
2062 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
2063 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
2064 Define as macros, as well as as enums or as constants.
2066 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
2068 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
2069 to keypad keys (Bug#12816).
2071 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2073 Minor adjustments of recently-changed frame functions.
2074 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
2075 known to be a frame (we're in the FRAMEP branch).
2076 * lisp.h (Qframep): Remove decl. frame.h declares this.
2077 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
2078 since they're meant for Lisp fixnum values.
2080 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2082 * window.c (Fwindow_combination_limit): Revert to the only
2083 required argument and adjust docstring as suggested in
2084 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
2085 by Martin Rudalics <rudalics@gmx.at>.
2087 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2089 Widely used frame validity and checking functions.
2090 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
2091 * frame.c (decode_live_frame, decode_any_frame): New functions.
2092 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
2093 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
2094 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)

2101 (frame_buffer_list, frame_buffer_predicate): Remove.
2102 * lisp.h (frame_buffer_predicate): Remove prototype.
2103 * buffer.c (Fother_buffer): Use decode_any_frame.
2104 * xdisp.c (Ftool_bar_lines_needed): Likewise.
2105 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
2106 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
2107 (Fclose_font, Ffont_info): Use decode_live_frame.
2108 * fontset.c (check_fontset_name): Likewise.
2109 * terminal.c (Fframe_terminal): Likewise.
2110 * w32fns.c (check_x_frame): Likewise.
2111 * window.c (Fminibuffer_window, Fwindow_at)
2112 (Fcurrent_window_configuration): Likewise.
2113 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
2114 Likewise. Allow zero number of arguments. Adjust docstring.
2115 * dispnew.c (Fredraw_frame): Likewise.
2116 * xfaces.c (frame_or_selected_frame): Remove.
2117 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
2118 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
2119 (Fframe_face_alist): Use decode_live_frame.
2120 * xfns.c (check_x_frame): Likewise.
2122 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2124 * window.c (quad): New function.
2125 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
2126 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
2127 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
2128 (Fwindow_line_height): Use it.
2129 (Fwindow_fringes): Use list3.
2130 (Fwindow_scroll_bars): Use list4.
2131 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
2132 (Fwindow_combination_limit): Allow zero number of arguments.
2134 2012-11-05 Eli Zaretskii <eliz@gnu.org>
2136 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
2138 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
2139 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
2140 file descriptor 2 for standard error. (Bug#12805)
2142 2012-11-05 Chong Yidong <cyd@gnu.org>
2144 * process.c (wait_reading_process_output): Revert previous change.
2146 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
2148 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
2149 This removes code that has been obsolete since around 1990.
2150 * callproc.c (Fcall_process):
2152 * process.c (create_process):
2153 * term.c (dissociate_if_controlling_tty):
2154 Assume setsid exists.
2155 * callproc.c (child_setup): Assume setpgid exists and behaves as
2156 per POSIX.1-1988 or later.
2157 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
2158 * emacs.c (shut_down_emacs):
2159 * sysdep.c (sys_suspend, init_foreground_group):
2160 Assume getpgrp behaves as per POSIX.1-1998 or later.
2161 * msdos.c (setpgrp): Remove.
2162 (tcgetpgrp, setpgid, setsid): New functions.
2163 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
2164 * term.c (no_controlling_tty): Remove; unused.
2165 * w32proc.c (setpgrp): Remove.
2166 (setsid, tcgetpgrp): New functions.
2168 Simplify by assuming __fpending.
2169 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
2170 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
2171 Do not assume that __fpending's result fits in int.
2173 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
2175 Remove EMACS_OUTQSIZE+sleep hack.
2176 * dispnew.c (update_frame_1): Remove hack for terminals slower
2177 than 2400 bps, which throttled Emacs by having it sleep.
2178 This code hasn't worked since at least 2007, when the multi-tty stuff
2179 was added, and anyway those old terminals are long dead.
2180 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
2181 without the dispnew.c change, as dispnew.c doesn't include systty.h.
2183 Fix data-loss with --version (Bug#9574).
2184 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
2185 as we can't assume that emacs_strerror is initialized, and strerror
2186 is good enough here.
2187 (main): Invoke atexit earlier, to catch earlier instances of
2188 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
2190 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
2192 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
2193 (keyDown): Remap keypad keys to X11 virtual key codes.
2195 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
2197 Fix data-loss with --batch (Bug#9574).
2198 * emacs.c: Include <close-stream.h>.
2199 (close_output_streams): New function.
2200 (main): Pass it to atexit, so that Emacs closes stdout and stderr
2201 and handles errors appropriately.
2202 (Fkill_emacs): Don't worry about flushing, as close_output_stream
2205 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
2206 The symptom is a diagnostic "GLib-WARNING **: In call to
2207 g_spawn_sync(), exit status of a child process was requested but
2208 SIGCHLD action was set to SIG_IGN and ECHILD was received by
2209 waitpid(), so exit status can't be returned." The diagnostic
2210 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
2211 The real bug is a race condition between Emacs and glib: Emacs
2212 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
2213 so that glib can't find it. Work around the bug by invoking
2214 waitpid only on subprocesses that Emacs itself creates.
2215 * process.c (create_process, record_child_status_change):
2216 Don't use special value -1 in pid field, as the caller now must
2217 know the pid rather than having the callee infer it.
2218 The inference was sometimes incorrect anyway, due to another race.
2219 (create_process): Set new 'alive' member if child is created.
2220 (process_status_retrieved): New function.
2221 (record_child_status_change): Use it.
2222 Accept negative 1st argument, which means to wait for the
2223 processes that Emacs already knows about. Move special-case code
2224 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
2225 processes that have already been waited for, by testing and
2226 clearing new 'alive' member.
2227 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
2228 now does this internally.
2229 (handle_child_signal): Let record_child_status_change do all
2230 the work, since we do not want to reap all exited child processes,
2231 only the child processes that Emacs itself created.
2232 * process.h (Lisp_Process): New boolean member 'alive'.
2234 Omit duplicate definitions no longer needed with gcc -g3.
2235 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
2236 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
2237 Define only as macros. There's no longer any need to also define
2238 these symbols as enums or as constants, since we now assume
2239 gcc -g3 when debugging.
2241 2012-11-03 Eli Zaretskii <eliz@gnu.org>
2243 * lisp.mk: Adjust comments to the fact that term/internal is now
2244 loaded from loadup.el.
2246 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
2247 (msdos_fatal_signal): New function.
2248 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
2251 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
2252 for GCC versions before 4.
2253 (emacs_raise): Define to call msdos_fatal_signal.
2255 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
2256 iterator when starting in the middle of a display or overlay
2259 2012-11-03 Chong Yidong <cyd@gnu.org>
2261 * process.c (wait_reading_process_output): Clean up the last
2264 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
2266 * process.c (wait_reading_process_output): Avoid a race condition
2267 with SIGIO delivery (Bug#11536).
2269 2012-11-03 Chong Yidong <cyd@gnu.org>
2271 * buffer.c (cursor_type): Untabify docstring.
2273 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2275 * frame.h (struct frame): Drop can_have_scroll_bars member
2276 which is meaningless for a long time. Adjust comments.
2277 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
2278 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
2280 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2282 * window.c (decode_next_window_args): Update window arg after
2283 calling decode_live_window and so fix crash reported at
2284 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
2285 by Juanma Barranquero <lekktu@gmail.com>.
2286 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
2287 * font.c (Ffont_at): Likewise.
2289 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
2291 * widget.c (resize_cb): New function.
2292 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
2293 (EmacsFrameResize): Check if all is up to date before changing frame
2296 2012-11-02 Eli Zaretskii <eliz@gnu.org>
2298 Implement backtrace output for fatal errors on MS-Windows.
2299 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
2300 (BACKTRACE_LIMIT_MAX): New macro.
2301 (w32_backtrace): New function.
2302 (emacs_abort): Use w32_backtrace when the user chooses not to
2303 attach a debugger. Update the text of the abort dialog.
2305 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2307 Window-related stuff cleanup here and there.
2308 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
2309 Use decode_any_window.
2310 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
2311 * xdisp.c (Fformat_mode_line): Likewise.
2312 * font.c (Ffont_at): Use decode_live_window.
2313 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
2314 * window.c (decode_next_window_args): Likewise.
2315 (decode_any_window): Remove static.
2316 * window.h (decode_any_window): Add prototype.
2317 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
2318 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
2321 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2323 Remove pad from struct input_event.
2324 * termhooks.h (struct input_event): Remove padding field.
2326 * keyboard.c (event_to_kboard): Simplify because frame_or_window
2327 member is never cons for a long time. Adjust comment.
2328 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
2329 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
2330 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
2331 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
2333 2012-11-01 Eli Zaretskii <eliz@gnu.org>
2335 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
2337 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
2339 Fix crash when using Emacs as commit editor for git (Bug#12697).
2340 * callproc.c (setpgrp): Remove macro, as we now use setpgid
2341 and it is configured in conf_post.h.
2342 (Fcall_process): Don't invoke both setsid and setpgid; the former
2343 is enough, if it exists.
2344 * callproc.c (Fcall_process, child_setup):
2345 * process.c (create_process): Use setpgid.
2346 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
2348 * dispnew.c (init_display): Initialize the foreground group
2349 if we are running a tty display.
2350 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
2351 * lisp.h (init_foreground_group): New decl.
2352 * sysdep.c (inherited_pgroup): New static var.
2353 (init_foreground_group, tcsetpgrp_without_stopping)
2354 (narrow_foreground_group, widen_foreground_group): New functions.
2355 (init_sys_modes): Narrow foreground group.
2356 (reset_sys_modes): Widen foreground group.
2358 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
2360 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
2362 2012-10-31 Martin Rudalics <rudalics@gmx.at>
2364 * minibuf.c (read_minibuf): Restore current buffer since
2365 choose_minibuf_frame calling Fset_frame_selected_window may
2366 change it (Bug#12766).
2368 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
2370 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
2372 2012-10-30 Kenichi Handa <handa@gnu.org>
2374 * font.c (Ffont_at): If WINDOW is specified and it is not
2375 displaying the current buffer, signal an error.
2377 2012-10-29 Daniel Colascione <dancol@dancol.org>
2379 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
2380 In preparation for fixing bug#12739, move these functions from
2383 * coding.h, coding.c: ... to here, and compile them only when
2384 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
2385 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
2387 2012-10-28 Eli Zaretskii <eliz@gnu.org>
2389 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
2390 (timer_loop, getitimer, setitimer): Use it instead of
2391 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
2393 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
2396 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
2398 * nsterm.m (NO_APPDEFINED_DATA): New define.

2400 (last_appdefined_event): Remove.
2401 (ns_select): Initialize t from last_appdefined_event_data instead
2402 of [last_appdefined_event data1].
2403 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
2404 remove last_appdefined_event (Bug#12698).
2406 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
2408 * frame.c (x_set_font): Catch internal error.
2410 2012-10-27 Eli Zaretskii <eliz@gnu.org>
2412 Avoid overflow in w32 implementation of interval timers.
2413 When possible, for ITIMER_PROF count only times the main thread
2415 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
2416 'volatile ULONGLONG' types. All the other data which was
2417 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
2418 (GetThreadTimes_Proc): New typedef.
2419 (w32_get_timer_time): New function, returns a suitable time value
2421 (timer_loop): Enter critical section when accessing ULONGLONG
2422 values of the itimer_data struct, as these accesses are no longer
2423 atomic. Call 'w32_get_timer_time' instead of 'clock'.
2424 Remove unused variable.
2425 (init_timers): Initialize s_pfn_Get_Thread_Times.
2426 (start_timer_thread): Don't assign itimer->caller_thread here.
2427 (getitimer): Assign itimer->caller_thread here.
2428 (setitimer): Always call getitimer to get the value of ticks_now.
2429 (sys_spawnve): Avoid compiler warning about format mismatch.
2431 2012-10-26 Eli Zaretskii <eliz@gnu.org>
2433 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
2434 mouse movement events if the menu bar is active. This avoids
2435 producing a busy "hour-glass" cursor by Windows if the mouse
2436 pointer is positioned over a tooltip shown for some menu item.
2438 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
2440 Don't assume process IDs fit in int.
2441 * emacs.c (shut_down_emacs) [!DOS_NT]:
2442 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
2443 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
2444 Use pid_t, not int, to store process IDs, as 'int'
2445 is not wide enough on a few platforms (e.g., AIX and IRIX).
2447 2012-10-23 Kenichi Handa <handa@gnu.org>
2449 The following change is to make face-font-rescale-alist work
2450 correctly for non-ASCII fonts.
2452 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
2453 (font_open_for_lface): Handle Vface_font_rescale_alist.
2455 2012-10-23 Chong Yidong <cyd@gnu.org>
2457 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
2459 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>

2468 2012-10-21 Glenn Morris <rgm@gnu.org>
2470 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
2472 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
2474 Port to OpenBSD 5.1.
2475 * frame.c (Fmouse_position, Fmouse_pixel_position):
2476 * xdisp.c (produce_stretch_glyph):
2477 Declare local vars only when they're needed.
2478 This is clearer and avoids a warning on OpenBSD about unused vars.

2480 This is safer, and avoids OpenBSD warnings about unused vars.
2481 * keyboard.c (record_menu_key): Remove unnecessary decl.
2482 (poll_timer): Define only if POLL_FOR_INPUT is defined.
2483 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
2484 as our definition clashes with OpenBSD's.
2485 * xfaces.c (load_face_colors, check_lface_attrs)
2486 (get_lface_attributes_no_remap, get_lface_attributes)
2487 (lface_fully_specified_p, x_supports_face_attributes_p)
2488 (tty_supports_face_attributes_p, face_fontset, realize_face)
2489 (realize_x_face, realize_tty_face):
2490 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
2491 merely Lisp_Object *. This is more informative and avoids
2492 a warning on OpenBSD about accessing beyond an object's size.
2494 2012-10-20 Chong Yidong <cyd@gnu.org>
2496 * lread.c (Fload): Doc fix (Bug#12592).

2522 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
2523 (staticpro): If we run out of staticpro slots, die with an
2524 informative error instead of just calling emacs_abort.
2526 2012-10-18 Martin Rudalics <rudalics@gmx.at>
2528 Fix two flaws reported by Dmitry Antipov.

2785 (get_input_pending): Remove first argument, since it was always
2786 the same pointer-to-int (now pointer-to-boolean) &input_pending,
2787 and behave as if it had that value. Return new value of
2788 input_pending. All callers changed.
2789 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
2790 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's

2806 initializer for PVEC_NORMAL_VECTOR.
2808 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
2810 Clean out old termopts cruft.
2811 * termopts.h (flow_control, meta_key): Remove unused decls.
2812 * dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c:
2813 Don't include termopts.h.
2815 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
2817 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
2819 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
2821 * commands.h (immediate_quit): Remove duplicate decl.
2823 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
2825 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles
2827 (nsfont_open): Remove setting of Vfonts_in_cache.
2828 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
2830 2012-10-09 Eli Zaretskii <eliz@gnu.org>
2832 * w32fns.c (w32_last_error): Change the return value to DWORD, to
2833 match what GetLastError returns. Explain why the function is
2836 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
2837 'is_tooltip_frame', to avoid confusion with its global namesake.
2839 2012-10-08 Daniel Colascione <dancol@dancol.org>
2841 * xdisp.c (start_hourglass): Call w32_note_current_window when
2842 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
2843 build that caused Emacs to display the hourglass cursor forever.
2845 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
2846 which is broken under remote desktop, calculate the number of
2847 colors available for a display based on the display's number of
2848 planes and number of bits per pixel per plane. (bug#10397).
2850 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
2852 * nsfont.m (Vfonts_in_cache): New variable.
2853 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
2854 are used. Add cached fonts to Vfonts_in_cache.
2855 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
2857 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
2859 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
2861 (FONT_H): Define after FRAME_H.
2862 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
2863 Update dependencies.
2865 * w32term.c: Remove leftover declaration of keyboard_codepage.
2867 2012-10-08 Eli Zaretskii <eliz@gnu.org>
2869 * makefile.w32-in (FONT_H): Add $(FRAME_H).
2870 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
2871 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
2872 (GLOBAL_SOURCES): Add cygw32.c.
2873 ($(BLD)/unexw32.$(O)):
2875 ($(BLD)/w32console.$(O)):
2876 ($(BLD)/w32fns.$(O)):
2877 ($(BLD)/w32heap.$(O)):
2878 ($(BLD)/w32menu.$(O)):
2879 ($(BLD)/w32proc.$(O)): Add w32common.h.
2881 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
2883 (x_to_w32_color): Don't modify the argument, modify a copy instead.
2885 2012-10-08 Daniel Colascione <dancol@dancol.org>
2887 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
2888 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
2889 accidental message numbering hole. Change other messages to
2892 * w32select.h (HAVE_W32SELECT): Remove.
2894 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
2895 w32common.h instead of w32heap.h.
2897 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
2898 (get_allocation_unit, get_processor_type, get_w32_major_version)
2899 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
2900 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
2901 (OS_NT, os_subtype, cache_system_info): Move declarations to
2904 * w32heap.c: Include w32common.h.
2905 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
2906 (w32_minor_version, w32_build_number, w32_subtype):
2907 Remove duplicate definitions.
2909 * w32fns.c: Include w32common.h; include w32heap.h only in
2912 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
2913 Use `report_file_error' instead of `error' in order to better
2914 inform users of what went wrong. Increase NTGUI_UNICODE file
2915 dialog box file name length to 32k, the maximum allowed by the NT
2918 * w32common.h: New file.
2919 (ROUND_UP, ROUND_DOWN, get_page_size)
2920 (get_allocation_unit, get_processor_type, get_w32_major_version)
2921 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
2922 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
2923 (OS_NT, os_subtype, cache_system_info): Move here.
2925 * unexw32.c, unexcw.c: Include w32common.h.
2927 * emacs.c (main): Use (defined (WINDOWSNT) || defined
2928 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
2929 to call syms_of_w32select.
2931 * cygw32.h: Remove obsolete EXFUN declarations.
2933 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
2935 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
2936 of w32inevt.o from SOME_MACHINE_OBJECTS.
2938 2012-10-08 Daniel Colascione <dancol@dancol.org>
2940 * image.c: Permanent fix for JPEG compilation issue --- limit
2941 jpeglib `boolean' redefinition to Cygwin builds.
2943 2012-10-08 Eli Zaretskii <eliz@gnu.org>
2945 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
2947 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
2950 2012-10-08 Daniel Colascione <dancol@dancol.org>
2952 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
2953 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
2954 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
2955 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
2956 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
2957 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
2958 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
2959 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
2960 now a supported configuration.
2962 * Makefile.in: consolidate image variables into LIBIMAGE; add
2963 W32_OBJ and W32_LIBS. Compile new files.
2966 (_DebPrint) declare tracing facility for W32 debugging. We need
2967 to unify tracing later.
2969 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
2970 unconditional use of W32 Unicode functions. Cygwin runs only on
2971 100% Unicode operating systems.
2973 * cygw32.c: New file. Define Cygwin-specific facilities.
2974 (Fcygwin_convert_path_to_windows)
2975 (Fcygwin_convert_path_from_windows): New user functions for
2976 accessing Cygwin path-munging routines.
2978 * cygw32.h: New file.
2979 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
2980 UTF-16LE strings temporarily inside non-Lisp-visible string
2983 (w32_strerror): Just what it says on the tin.
2985 * emacs.c: Make the NS fork-then-exec code for daemon-launching
2986 also run for Cygwin; both systems have the same problem with using
2987 GUI facilities in a forked child. Also call syms_of_cygw32,
2988 syms_of_w32select in correct places.
2990 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
2991 needs fork-then-exec for daemon launching.
2993 * font.h: Include frame.h.
2995 * image.c: Use the image library cache machinery only when we're
2996 compiling for native WINDOWSNT; Cygwin can use shared libraries
2997 like any other Unixlike system.
2999 * keyboard.c: Clarify a comment regarding the input loop.
3001 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
3002 functions directly instead of trying to detect at runtime that our
3003 host operating system supports them. We make this change for two
3004 reasons: Cygwin lacks support for the multibyte character
3005 conversion functions used by the legacy menu code, and Cygwin
3006 never needs to rely on non-Unicode APIs.
3008 * unexw32.c (hinst): Declare extern.
3010 * w32.c: Change header order;
3011 (w32_strerror): Move to w32fns.c because we need it for
3012 non-WINDOWSNT builds.
3014 * w32.h: Add #error macro to make sure we don't include w32.h for
3015 Cygwin builds. Remove w32select declarations.
3017 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
3018 w32fns.c. w32console.c is WINDOWSNT-only.
3020 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
3021 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
3023 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
3024 (w32_major_version, w32_minor_version, w32_build_number)
3025 (os_subtype, sound_type): Define here
3026 (w32_defined_color): Make color parameter const for consistency
3027 with other _defined_color functions.
3028 (w32_createwindow): Unconditionally call w32_init_class instead of
3029 doing so only when hprevinst is non-NULL. Plumbing hprevinst
3030 through the code is complex and unnecessary because class
3031 registration is practically free.
3032 (w32_name_of_message): New EMACSDEBUG-only function.
3033 (Fset_message_beep): Move here
3034 (Fx_open_connection): Require that the display name for Windows be
3035 "w32" for consistency, emacsclient disambiguation, and maybe, one
3036 day, multi-window-system support.
3037 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
3038 Cygwin files for W32 GUI facilities, since these clearly don't
3039 expect Cygwin names.
3040 (_DebPrint): Define.
3041 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
3042 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
3043 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
3044 (w32_last_error): Remove.
3046 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
3048 * w32heap.c (syspage_mask): Declare here.
3049 (cache_system_info): Remove.
3051 * w32inevt.c (faked_key): Define globally, not statically.
3052 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
3053 (w32_console_toggle_lock_key): Move to w32fns.c.
3055 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
3057 * w32proc.c (_DebPrint): Move to w32fns.c.
3058 * w32select.c: Include string.h, stdio.h for Cygwin.
3059 * w32select.h: New File.
3061 * w32term.c: Include io.h for non-CYGWIN builds; needed for
3063 (w32_message_fd): New variable. Under Cygwin, holds the file
3064 descriptor the system used to tell us about pending thread
3067 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
3068 that prevented compilation under non-WINDOWSNT systems.
3070 (w32_initialize): Open /dev/windows and assign it to
3071 w32_message_fd. Provide w32 feature.
3073 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
3074 (WM_EMACS_INPUT_READY): add.
3075 (prepend_msg, w32_message_fd): Declare globally.
3078 (keyboard_handle): Use only when WINDOWSNT.
3079 (notify_msg_ready): New function. Posts a message to the main
3080 thread's message queue under CYGWIN, which wakes up the main
3081 thread from select(2) by making the /dev/windows file descriptor
3082 ready. Under WINDOWSNT, it sets an event the same way the old
3085 (post, prepend_msg): Actually call notify_msg_ready instead of
3086 setting the input event directly.
3088 2012-10-07 Eli Zaretskii <eliz@gnu.org>
3090 * ralloc.c (relinquish): If a heap is ready to be relinquished,
3091 but it still has blocs in it, don't return it to the system,
3092 instead of aborting. (Bug#12402)
3094 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
3096 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
3098 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
3099 MAC_OS_X_VERSION_10_6.
3100 (syms_of_nsterm): Remove comment about Panther and above for
3102 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
3103 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
3104 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
3106 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
3107 MAC_OS_X_VERSION_10_4.
3109 * nsmenu.m (fillWithWidgetValue:): Remove code for <
3110 MAC_OS_X_VERSION_10_2.
3112 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
3114 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
3115 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
3117 * nsterm.m (ns_in_resize): Remove (Bug#12479).
3118 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
3119 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
3120 Remove ns_in_resize check.
3121 (ns_clear_frame_area): Remove resize handle code.
3123 * nsfns.m (ns_in_resize): Remove.
3124 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
3125 Remove ns_in_resize check.
3127 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
3129 Improve sys_siglist detection.
3130 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
3131 defined as a macro, as is done in Solaris.
3132 (sys_siglist_entries): New macro.
3133 (save_strsignal): Use it.
3134 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
3135 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
3137 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
3139 * nsfns.m (Fx_create_frame): Call x_default_parameter with
3140 fullscreen/Fullscreen.
3142 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
3143 tobar_height is new.
3145 * nsterm.m (x_make_frame_visible): Check for fullscreen.
3146 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
3147 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
3148 (windowDidResize:): Check for correct window if old style fullscreen.
3149 Capitalize word in comment. Remove incorrect comment.
3150 (initFrameFromEmacs:): tbar_height renamed tibar_height.
3151 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
3152 error in drawing background.
3153 (toggleFullScreen:): Remove comment. Rearrange calls.
3154 Set toolbar values to zero, save old height in tobar_height.
3155 Restore tool bar height when leaving fullscreen.
3156 (canBecomeMainWindow): New function.
3158 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
3160 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
3162 2012-10-05 Eli Zaretskii <eliz@gnu.org>
3164 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
3166 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
3167 that time stamps of directories could also be changed.
3168 Don't request the too broad GENERIC_WRITE, only the more restrictive
3169 FILE_WRITE_ATTRIBUTES access rights.
3171 * fileio.c (Fset_file_times): Special-case ignoring errors for
3172 directories only on MSDOS, not on MS-Windows.
3174 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
3176 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
3178 2012-10-04 Eli Zaretskii <eliz@gnu.org>
3180 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
3181 see whether CreateFile failed.
3183 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
3185 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
3186 to avoid similar races.
3187 * keyboard.c (pending_signals): Now bool, not int.
3189 Port timers to OpenBSD, plus check for timer failures.
3190 OpenBSD problem reported by Han Boetes.
3191 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
3193 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
3194 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
3195 like OpenBSD, which has timer_settime but does not declare it.
3196 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
3197 whether to use itimerspec-related primitives. All uses of
3198 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
3200 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3202 * profiler.c (handle_profiler_signal): Fix a malloc race
3203 that caused Emacs to hang on Fedora 17 when profiling Lisp.
3205 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
3207 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
3209 2012-10-02 Eli Zaretskii <eliz@gnu.org>
3211 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
3212 consistent with the change in return value of 'safe_strsignal'.
3214 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3216 Prefer plain 'static' to 'static inline' (Bug#12541).
3217 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
3218 (bidi_set_sor_type, bidi_push_embedding_level)
3219 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
3220 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
3221 (bidi_cache_search, bidi_cache_ensure_space)
3222 (bidi_cache_iterator_state, bidi_cache_find)
3223 (bidi_peek_at_next_level, bidi_set_paragraph_end)
3224 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
3225 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
3226 Now 'static', not 'static inline'.
3228 Count overruns when profiling; change units to ns.
3229 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
3230 Give extra weight to samples after overruns, to attempt to count
3231 the time more accurately.
3232 (setup_cpu_timer): Change sampling interval units from ms to ns, since
3233 the underlying primitives nominally do ns.
3234 (Fprofiler_cpu_start): Document the change. Mention that
3235 the sampling intervals are only approximate.
3237 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
3239 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
3241 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
3242 case for the special 0 coding-system.
3244 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
3245 (Fmake_overlay): Remove redundant tests.
3246 (fix_start_end_in_overlays): Remove redundant recentering.
3248 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
3250 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
3251 Update dependencies.
3253 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3255 Fix a malloc race condition involving strsignal.
3256 A signal can arrive in the middle of a malloc, and Emacs's signal
3257 handler can invoke strsignal, which can invoke malloc, which is
3258 not portable. This race condition bug makes Emacs hang on GNU/Linux.
3259 Fix it by altering the signal handler so that it does not invoke
3261 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
3262 * process.c (status_message): Use const pointer, in case strsignal
3263 is #defined to safe_strsignal.
3264 * sysdep.c (sys_siglist, init_signals): Always define and
3265 initialize a substitute sys_siglist if the system does not define
3266 one, even if HAVE_STRSIGNAL.
3267 (safe_strsignal): Rename from strsignal. Always define,
3268 using sys_siglist. Return a const pointer.
3269 * syssignal.h (safe_strsignal): New decl.
3270 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
3272 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3274 * w32proc.c (timer_loop): Fix code that waits for timer
3275 expiration, to avoid high CPU usage.
3277 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
3279 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
3280 (sweep_weak_table): Remove redundant prototypes.
3282 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
3284 * emacs.c: Move the inclusion of TERM_HEADER after including
3285 windows.h on WINDOWSNT. This avoids compilation problems with
3288 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3290 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
3291 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
3292 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
3293 as the previous version used 'void *'.
3295 * ralloc.c (ROUNDUP): Fix last change.
3296 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
3299 * w32proc.c <disable_itimers>: New static flag.
3300 (init_timers): Initialize it to zero, after creating the critical
3301 sections used by the timer threads.
3302 (term_timers): Set to 1 before deleting the critical sections.
3303 (getitimer, setitimer): If disable_itimers is non-zero, return an
3304 error indication without doing anything. Reported by Fabrice
3305 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
3306 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
3308 [!HAVE_SETITIMER]: Behave as the previous version that didn't
3311 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
3312 term_ntproc after all the other bookkeeping, to get timers working
3313 as long as possible.
3315 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3317 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
3318 Suggested by Juri Linkov in
3319 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
3321 Prefer plain 'static' to 'static inline' (Bug#12541).
3322 With static functions, modern compilers inline pretty well by
3323 themselves; advice from programmers often hurts as much as it helps.
3324 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
3325 this change shrinks the text size of the Emacs executable by 1.1%
3326 without affecting CPU significantly in my benchmark.
3327 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

3406 (bidi_copy_it): Do the whole copy with a single memcpy.
3407 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
3409 Revert the FOLLOW-SYMLINKS change for file-attributes.
3410 Doing it right would require several changes to Tramp, and there's
3411 not enough time to get that tested before the freeze today.
3412 * dired.c (directory_files_internal, Ffile_attributes):
3415 * frame.c (x_report_frame_params): Port better to wider ints.
3416 Do not assume that EMACS_UINT is the same width as uprintmax_t,
3417 or that pointers can be printed in 15 decimal digits.
3418 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

3454 * vm-limit.c (lim_data): Now size_t.
3455 (check_memory_limits): Adjust prototypes of real_morecore and
3456 __morecore to receive argument of type ptrdiff_t. Use size_t for

3482 * frame.c (x_report_frame_params): Use EMACS_UINT for the return
3483 value of FRAME_X_WINDOW, to fit a 64-bit pointer on 64-bit Windows

3609 Profiler improvements: more-accurate timers, overflow checks.
3610 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
3611 signal.h, setjmp.h. Include systime.h instead.
3612 (saturated_add): New function.

3619 All uses changed to store the new value.
3620 (handle_profiler_signal): Rename from sigprof_handler_1,
3621 for consistency with other handlers. Do not check whether
3622 cpu_log is a hash-table if garbage collecting, since it
3623 doesn't matter in that case.

3625 for consistency with other handlers.
3626 (setup_cpu_timer): New function, with much of what used to be in
3627 Fprofiler_cpu_start. Check for out-of-range argument.
3628 Prefer timer_settime if available, and prefer
3629 thread cputime clocks, then process cputime clocks, then
3630 monotonic clocks, to the old realtime clock. Use make_timeval
3631 to round more-correctly when falling back to setitimer.
3632 (Fprofiler_cpu_start): Use it.
3633 (Fprofiler_cpu_stop): Prefer timer_settime if available.
3634 Don't assume that passing NULL as the 2nd argument of setitimer
3635 is the same as passing a pointer to all-zero storage.
3636 Ignore SIGPROF afterwards.
3637 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
3638 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
3639 non-fatal signal handlers. Ignore SIGPROF on startup.
3640 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
3641 in profiler.c, since sysdep.c now uses it.
3643 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

3699 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
3700 Since this stuff is now private to charset.c, there's no need for
3701 a public macro and no need to inline by hand.

3730 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
3732 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
3734 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
3736 Prefer POSIX timers if available.
3737 They avoid a race if the timer is too close to the current time.
3738 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
3739 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
3740 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
3742 2012-09-25 Eli Zaretskii <eliz@gnu.org>
3744 * coding.c (CHAR_STRING_ADVANCE_NO_UNIFY): Make it an alias of
3745 CHAR_STRING_ADVANCE.
3746 (STRING_CHAR_ADVANCE_NO_UNIFY): Make it an alias of
3747 STRING_CHAR_ADVANCE.
3749 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
3751 Move Vlibrary_cache to emacs.c and reset before dumping.
3753 * lisp.h (reset_image_types): Declare.
3754 [WINDOWSNT] (Vlibrary_cache): Declare.
3756 * image.c (reset_image_types): New function.
3758 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.

3765 * w32.h (Vlibrary_cache): Do not declare.
3767 2012-09-25 Eli Zaretskii <eliz@gnu.org>
3769 * w32proc.c (sys_signal): Handle all signals defined by the
3770 MS-Windows runtime, not just SIGCHLD. Actually install the signal
3771 handlers for signals supported by Windows. Don't override
3772 term_ntproc as the handler for SIGABRT.
3773 (sigaction): Rewrite to call sys_signal instead of duplicating its
3775 (sys_kill): Improve commentary.
3777 * w32.c (term_ntproc): Accept (and ignore) one argument, for
3778 consistency with a signature of a signal handler. All callers
3780 (init_ntproc): Accept an argument DUMPING. If dumping, don't
3781 install term_ntproc as a signal handler for SIGABRT, as that
3782 should be done by the dumped Emacs.
3784 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
3786 * w32select.c (term_w32select): Protect against repeated
3787 invocation by setting clipboard_owner to NULL after calling

3791 and term_ntproc to their modified signatures.
3793 * character.c (char_string, string_char): Remove calls to
3794 MAYBE_UNIFY_CHAR. See the discussion starting at
3795 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
3798 2012-09-25 Chong Yidong <cyd@gnu.org>
3800 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
3802 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
3804 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
3805 when encountering an unknown bytecode.
3807 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
3809 image.c, indent.c: Use bool for booleans.
3810 * dispextern.h (struct image_type): Members valid_p, load, init
3811 now return bool, not int. All uses changed.
3812 * image.c: Omit unnecessary static decls.
3813 (x_create_bitmap_mask, x_build_heuristic_mask):
3814 Return void, not int, since callers don't care about the return value.

3843 Use bool for booleans.
3845 2012-09-24 Chong Yidong <cyd@gnu.org>
3847 * chartab.c (Fset_char_table_default): Obsolete function removed.
3849 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3851 Move pid_t related decls out of lisp.h.
3852 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
3853 (interruptible_wait_for_termination):
3854 Move these decls from lisp.h to syswait.h, since they use pid_t.
3855 Needed on FreeBSD; see Herbert J. Skuhra in
3856 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
3857 * callproc.c: Include syswait.h.

3875 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
3876 * xfns.c (Fx_show_tip) [USE_GTK]:
3877 Use bool for boolean.
3878 * gtkutil.c (xg_update_frame_menubar):
3879 * xmenu.c (update_frame_menubar):
3880 Return void, not int, since caller ignores return value.
3881 * gtkutil.c (xg_change_toolbar_position):
3884 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
3886 * makefile.w32-in (BLOCKINPUT_H): Remove.

3903 2012-09-23 Eli Zaretskii <eliz@gnu.org>
3905 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
3906 fatal_error_backtrace.
3908 * w32proc.c (sys_kill): Undo last change: don't do anything when
3909 invoked to deliver SIGABRT to our own process. This is now
3910 handled by emacs_raise.
3912 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
3914 * w32term.c (w32_read_socket): Remove leftover reference to
3915 interrupt_input_pending.
3917 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3919 Do not use SA_NODEFER.
3920 Problem reported by Dani Moncayo in
3921 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
3923 * sysdep.c (emacs_abort): Do not reset signal handler.
3924 * emacs.c (terminate_due_to_signal): Reset signal handler here.
3925 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
3926 wanted even on POSIXish hosts, and it doesn't work on Windows.
3928 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3930 * xterm.c (x_term_init): Call fixup_locale before and after calling
3931 gtk_init (Bug#12392).
3933 2012-09-23 Chong Yidong <cyd@gnu.org>
3935 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
3936 Vdynamic_library_alist.
3938 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
3939 (Fgnutls_available_p): Caller changed.
3941 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
3942 (Flibxml_parse_xml_region): Likewise.
3944 * dispextern.h (struct image_type): Remove arg from init function.
3946 * image.c (Finit_image_library, lookup_image_type)
3947 (define_image_type): Remove now-unneeded second arg.
3948 (init_xpm_functions, init_png_functions, init_jpeg_functions)
3949 (init_tiff_functions, init_gif_functions, init_svg_functions):
3950 Arglist and w32_delayed_load calling convention changed.
3951 (gs_type): Remove init_gs_functions; there is no such function.
3952 (valid_image_p, make_image): Fix caller to lookup_image_type.
3954 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3956 Simplify and avoid signal-handling races (Bug#12471).
3958 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
3959 Avoid recursive loop if there's a fatal error in the function itself.
3960 * atimer.c (pending_atimers):
3961 * blockinput.h: Don't include "atimer.h"; no longer needed.
3962 (interrupt_input_pending): Remove. All uses removed.
3963 pending_signals now counts both atimers and ordinary interrupts.
3964 This is less racy than having three separate pending-signal flags.
3965 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
3967 Rename from their upper-case counterparts BLOCK_INPUT,
3968 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
3969 INPUT_BLOCKED_P, and turn into functions. All uses changed.
3970 This makes it easier to access volatile variables more accurately.
3971 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
3972 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
3973 that's more reliable if the code is buggy and sets
3974 interrupt_input_blocked to a negative value. All uses changed.
3975 * atimer.c (deliver_alarm_signal):
3976 Remove. No need to deliver this to the parent; any thread can
3977 handle this signal now. All uses replaced by underlying handler.
3978 * atimer.c (turn_on_atimers):
3979 * dispnew.c (handle_window_change_signal):
3980 * emacs.c (handle_danger_signal):
3981 * keyboard.c (kbd_buffer_get_event):
3982 Don't reestablish signal handler; not needed with sigaction.
3983 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
3985 Rework to avoid unnecessary accesses to volatile variables.
3986 (UNBLOCK_INPUT_TO): Now a function.
3987 (totally_unblock_input, unblock_input): New decls.
3988 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
3989 (init_data): Remove. Necessary stuff now done in init_signal.
3990 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
3991 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
3992 (fatal_error_code): Remove; no longer needed.
3993 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
3994 it doesn't always backtrace. All uses changed. No need to reset
3995 signal to default, since sigaction and/or die does that for us now.
3996 Use emacs_raise (FOO), not kill (getpid (), FOO).
3997 (main): Check more-accurately whether we're dumping.
3998 Move fatal-error setup to sysdep.c
3999 * floatfns.c: Do not include "syssignal.h"; no longer needed.
4000 * gtkutil.c (xg_get_file_name, xg_get_font):
4001 Remove no-longer-needed signal-mask manipulation.
4002 * keyboard.c, process.c (POLL_FOR_INPUT):
4003 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
4004 * keyboard.c (read_avail_input): Remove.
4005 All uses replaced by gobble_input.
4006 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
4007 (kbd_buffer_store_event_hold, gobble_input):
4008 (record_asynch_buffer_change) [USABLE_SIGIO]:
4009 (store_user_signal_events):
4010 No need to mess with signal mask.
4011 (gobble_input): If blocking input and there are terminals, simply
4012 set pending_signals to 1 and return. All hooks changed to not
4013 worry about whether input is blocked.
4014 (process_pending_signals): Clear pending_signals before processing
4015 them, in case a signal comes in while we're processing.
4016 By convention callers now test pending_signals before calling us.
4017 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
4018 New functions, to support changes to blockinput.h.
4019 (handle_input_available_signal): Now extern.
4020 (reinvoke_input_signal): Remove. All uses replaced by
4022 (quit_count): Now volatile, since a signal handler uses it.
4023 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
4024 All callers changed. Block SIGINT only if not already blocked.
4025 Clear sigmask reliably, even if Fsignal returns, which it can.
4026 Omit unnecessary accesses to volatile var.
4027 (quit_throw_to_read_char): No need to restore sigmask.
4028 * keyboard.c (gobble_input, handle_user_signal):
4029 * process.c (wait_reading_process_output):
4030 Call signal-handling code rather than killing ourselves.
4031 * lisp.h: Include <float.h>, for...
4032 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
4033 (pending_signals): Now volatile.
4034 (syms_of_data): Now const if IEEE floating point.
4035 (handle_input_available_signal) [USABLE_SIGIO]:
4036 (terminate_due_to_signal, record_child_status_change): New decls.
4037 * process.c (create_process): Avoid disaster if memory is exhausted
4038 while we're processing a vfork, by tightening the critical section
4040 (send_process_frame, process_sent_to, handle_pipe_signal)
4041 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
4043 (send_process): No need for setjmp/longjmp any more, since the
4044 SIGPIPE stuff is now gone. Instead, report an error if errno
4046 (record_child_status_change): Now extern. PID and W are now args.
4047 Return void, not bool. All callers changed.
4048 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
4049 Remove. All uses removed. This bug should be fixed now in a
4051 (wait_for_termination_1): Use waitpid rather than sigsuspend,
4052 and record the child status change directly. This avoids the
4053 need to futz with the signal mask.
4054 (process_fatal_action): Move here from emacs.c.
4055 (emacs_sigaction_flags): New function, containing
4056 much of what used to be in emacs_sigaction_init.
4057 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
4058 caught by emacs, to make races less likely.
4059 (deliver_process_signal): Rename from handle_on_main_thread.
4061 (BACKTRACE_LIMIT_MAX): Now at top level.
4062 (thread_backtrace_buffer, threadback_backtrace_pointers):
4064 (deliver_thread_signal, deliver_fatal_thread_signal):
4065 New functions, for more-accurate delivery of thread-specific signals.
4066 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
4067 (deliver_arith_signal): Handle in this thread, not
4068 in the main thread, since it's triggered by this thread.
4069 (maybe_fatal_sig): New function.
4070 (init_signals): New arg DUMPING so that we can be more accurate
4071 about whether we're dumping. Caller changed.
4072 Treat thread-specific signals differently from process-general signals.
4073 Block all signals while handling fatal error; that's safer.
4074 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
4076 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
4077 Ignore SIGPIPE unless batch.
4078 (emacs_backtrace): Output backtrace for the appropriate thread,
4079 which is not necessarily the main thread.
4080 * syssignal.h: Include <stdbool.h>.
4081 (emacs_raise): New macro.
4082 * xterm.c (x_connection_signal): Remove; no longer needed
4083 now that we use sigaction.
4084 (x_connection_closed): No need to mess with sigmask now.
4085 (x_initialize): No need to reset SIGPIPE handler here, since
4086 init_signals does this for us now.
4088 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4090 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
4091 background rect may be larger (Bug#12245).
4093 2012-09-23 Chong Yidong <cyd@gnu.org>
4095 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
4097 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4099 * .gdbinit: Just stop at fatal_error_backtrace.
4100 See Stefan Monnier's request in
4101 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
4102 Remove no-longer-used query of system type.
4104 2012-09-22 Chong Yidong <cyd@gnu.org>
4106 * search.c (Freplace_match): Doc fix (Bug#12325).
4108 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
4110 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
4111 (Fline_end_position): Doc fix.
4113 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
4115 2012-09-22 Chong Yidong <cyd@gnu.org>
4117 * dispextern.h (struct image_type): Add new slot, storing a type
4118 initialization function.
4120 * image.c (define_image_type): Call the image initializer function
4121 if it is defined. Arguments and return value changed.
4122 (valid_image_p, make_image): Callers changed.
4123 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
4124 (gif_type, imagemagick_type, svg_type, gs_type):
4125 Add initialization functions.
4126 (Finit_image_library): Call lookup_image_type.
4127 (CHECK_LIB_AVAILABLE): Macro deleted.
4128 (lookup_image_type): Call define_image_type here, rather than via
4129 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
4130 (syms_of_image): Move define_image_type calls for xbm_type and
4131 pbm_type to lookup_image_type.
4133 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4135 * keyboard.c (timer_check_2): Move calculation of 'timers' and
4136 'idle_timers' from here ...
4137 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
4138 lists, to avoid infloops when the timer does something stupid,
4139 like reinvoke itself with the same or smaller time-out.
4142 2012-09-22 Martin Rudalics <rudalics@gmx.at>
4144 * window.c (Fsplit_window_internal): Handle only Qt value of
4145 Vwindow_combination_limit separately.
4146 (Qtemp_buffer_resize): New symbol.
4147 (Vwindow_combination_limit): New default value.
4150 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4152 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
4153 the new overlay string. (Bug#10159)
4155 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4157 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
4158 or that fprintf is async-signal-safe. POSIX doesn't require
4161 2012-09-22 Chong Yidong <cyd@gnu.org>
4163 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
4166 2012-09-22 Kenichi Handa <handa@gnu.org>
4168 * composite.c (composition_reseat_it): Handle the case that a
4169 grapheme cluster is not covered by a single font (Bug#12352).
4171 2012-09-21 Chong Yidong <cyd@gnu.org>
4173 * image.c (define_image_type): Avoid adding duplicate types to
4174 image_types (Bug#12463). Suggested by Jörg Walter.
4176 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4178 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
4179 (print_load_command_name): Add case LC_DATA_IN_CODE.
4180 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
4182 2012-09-21 Glenn Morris <rgm@gnu.org>
4184 * eval.c (Frun_hook_with_args_until_success)
4185 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
4187 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
4189 * fileio.c (Ffile_selinux_context): Only call freecon when
4190 lgetfilecon succeeded.
4191 (Fset_file_selinux_context): Likewise. (Bug#12444)
4193 2012-09-21 Eli Zaretskii <eliz@gnu.org>
4195 * xdisp.c (try_window_reusing_current_matrix): Under bidi
4196 reordering, locate the cursor by calling set_cursor_from_row; if
4197 that fails, clear the desired glyph matrix before returning a
4198 failure indication to the caller. Fixes leaving garbled display
4199 when fast scrolling with a down-key. (Bug#12403)
4200 (compute_stop_pos_backwards): Fix a typo that caused crashes while
4201 scrolling through multibyte text.
4203 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
4205 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
4206 calling mark_vectorlike since that's the one that marks the window.
4207 (mark_discard_killed_buffers): Mark the final cdr.
4208 * window.h (struct window): Move prev/next_buffers to the
4209 non-standard fields.
4210 * window.c (make_window): Initialize prev/next_buffers manually.
4212 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
4214 Omit unused arg EXPECTED from socket hooks.
4215 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
4216 * nsterm.m (ns_term_init):
4217 * termhooks.h (struct terminal.read_socket_hook):
4218 * w32inevt.c (w32_console_read_socket):
4219 * w32term.c (w32_read_socket):
4220 * xterm.c (XTread_socket):
4221 Omit unused arg EXPECTED. All callers changed.
4222 (store_user_signal_events): Return void, not int, since callers no
4223 longer care about the return value. All uses changed.
4225 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
4227 * w32gui.h (XParseGeometry): Do not declare.
4229 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
4231 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
4232 Ignore 'expected'. See Eli Zaretskii in
4233 <http://bugs.gnu.org/12471#8> (last line).
4235 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
4236 (XParseGeometry): Now static. Substitute extremal values for
4237 values that are out of range.
4239 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
4241 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
4243 * nsfns.m (XParseGeometry): Remove.
4244 (Fx_create_frame): Call x_set_offset to correctly interpret
4245 top_pos in geometry.
4247 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
4248 (Fx_parse_geometry): If there is a space in string, call
4249 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
4251 2012-09-17 Eli Zaretskii <eliz@gnu.org>
4253 * search.c (scan_buffer): Use character positions in calls to
4254 region_cache_forward and region_cache_backward, not byte
4255 positions. (Bug#12196)
4257 * w32term.c (w32_read_socket): Set pending_signals to 1, like
4258 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
4260 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
4261 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
4262 emacs_blocked_malloc, now deleted.
4264 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
4266 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
4267 The workaround was for improving performance on Solaris 2.4, but
4268 is getting in the way now. Emacs will still work if someone is
4269 still running Solaris 2.4 in a museum somewhere; Sun dropped
4270 support for Solaris 2.4 in 2003.
4271 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
4272 * process.c (create_process) [HAVE_WORKING_VFORK]:
4273 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
4274 since Emacs no longer uses vfork on that platform.
4276 2012-09-17 Glenn Morris <rgm@gnu.org>
4278 * emacs.c: Use COPYRIGHT.
4280 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
4282 Remove configure's --without-sync-input option (Bug#12450).
4283 When auditing signal-handling in preparation for cleaning it up,
4284 I found that SYNC_INPUT has race conditions and would be a real
4285 pain to fix. Since it's an undocumented and deprecated
4286 configure-time option, now seems like a good time to remove it.
4287 Also see <http://bugs.gnu.org/11080#16>.
4288 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
4289 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
4290 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4291 (malloc_hysteresis):
4292 (check_depth) [XMALLOC_OVERRUN_CHECK]:

4296 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
4297 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
4298 [!SYSTEM_MALLOC && !SYNC_INPUT]:
4299 Remove. All uses removed.
4300 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
4301 implementation, one that depends on whether the new macro
4302 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
4304 * atimer.c (run_timers, handle_alarm_signal):
4305 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
4306 (handle_async_input, process_pending_signals)
4307 (handle_input_available_signal, init_keyboard):
4308 * nsterm.m (ns_read_socket):
4309 * process.c (wait_reading_process_output):
4310 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):

4313 * xterm.c (XTread_socket):
4315 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
4316 * eval.c (handling_signal): Remove. All uses removed.
4317 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
4318 All uses replaced with the SYNC_INPUT version.
4319 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
4321 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4324 * font.c (Ffont_shape_gstring): Remove unused local.
4326 2012-09-16 Glenn Morris <rgm@gnu.org>
4328 * Makefile.in (clean): No longer run nextstep's clean.
4330 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
4332 (ns-app): Move here from ns.mk, and simplify.
4333 (clean): Simplify nextstep entry.
4334 * ns.mk: Remove file.
4336 2012-09-17 Kenichi Handa <handa@gnu.org>
4338 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
4339 not covert the last few charactes.
4341 2012-09-16 Kenichi Handa <handa@gnu.org>
4343 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
4344 here, but just check the validity of glyphs in the glyph-string.
4346 2012-09-16 Martin Rudalics <rudalics@gmx.at>
4348 * window.c (Fwindow_parameter, Fset_window_parameter):
4349 Accept any window as argument (Bug#12452).
4351 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
4353 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
4354 to ns_term_init to avoid memory leak.
4356 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
4357 explicit retain/release.
4358 (ns_term_init): Only allow one display. Initialize outerpool and
4361 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4363 Port _setjmp fix to POSIXish hosts as well as Microsoft.
4364 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
4365 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
4366 the Microsoft problem in a different way, by altering ../nt/config.nt.
4368 2012-09-15 Eli Zaretskii <eliz@gnu.org>
4383 * w16select.c: Remove inclusion of setjmp.h, as it is now included
4384 by lisp.h. This completes removal of setjmp.h inclusion
4385 erroneously announced in the previous commit. (Bug#12446)
4387 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
4390 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
4391 not defined as a macro. The latter happens on MS-Windows.
4394 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4396 Port better to POSIX hosts lacking _setjmp (Bug#12446).
4397 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
4398 Some instances of '#include <setjmp.h>' removed, if the
4399 only reason for the instance was because "lisp.h" was included.
4400 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
4401 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
4402 and _longjmp with the new symbols. Emacs already uses _setjmp if
4403 available, so this change affects only POSIXish hosts that have
4404 sigsetjmp but not _setjmp, such as some versions of Solaris and
4405 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
4406 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
4407 (png_load_body) [HAVE_PNG]:
4408 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
4409 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
4410 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
4411 since PNG requires jmp_buf. This is the only exception to the
4412 general rule that we now use sys_setjmp and sys_longjmp.
4413 This exception is OK since this code does not change the signal
4414 mask or longjmp out of a signal handler.
4416 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
4418 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4419 Include "syssignal.h", for 'main_thread'.
4421 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
4423 Avoid out-of-range marker position (Bug#12426).
4424 * insdel.c (replace_range, replace_range_2):
4425 Adjust markers before overlays, as suggested by comments.
4426 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
4427 Remove redundant check before calling offset_intervals.
4429 2012-09-14 Martin Rudalics <rudalics@gmx.at>
4431 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
4432 current buffer (Bug#12387).
4434 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
4436 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
4438 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4440 Use a more backwards-compatible timer format (Bug#12430).
4441 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
4442 vector element, not from the 4th, since PSECS is now at the end.
4443 (Fcurrent_idle_time): Doc fix.
4445 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
4447 Function to mark objects and remove killed buffers at once.
4448 * alloc.c (discard_killed_buffers): Rename to ...
4449 (mark_discard_killed buffers) ... new name. Add marking
4450 of remaining objects. Fix comment. Adjust users.
4451 (mark_object): Do not touch frame buffer lists here.
4452 * frame.c (delete_frame): Reset frame buffer lists here.
4454 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4456 Better workaround for GNOME bug when --enable-gcc-warnings.
4457 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
4458 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
4459 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
4461 Simplify SIGIO usage (Bug#12408).
4462 The code that dealt with SIGIO was crufty and confusing, e.g., it
4463 played tricks like "#undef SIGIO" but these tricks were not used
4464 consistently. Simplify mostly by not #undeffing standard symbols,
4465 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
4466 or not as we please) rather than "defined SIGIO" (standard symbol
4467 that we probably shouldn't #undef).
4468 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
4469 Modules that need it can include it.
4470 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
4471 * dispextern.h (ignore_sigio): New decl.
4472 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
4473 unconditionally, since it's now a no-op if !USABLE_SIGIO.
4474 * emacs.c (shut_down_emacs):
4475 * keyboard.c (kbd_buffer_store_event_hold):
4476 Use ignore_sigio rather than invoking 'signal' directly.
4477 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
4479 (FIONREAD, SIGIO): Do not #undef.
4480 (tty_read_avail_input): Use #error rather than a syntax error.
4481 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
4482 for I_PIPE, used by SETUP_SLAVE_PTY.
4483 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
4484 * sysdep.c (croak): Remove; no longer needed. This bit of
4485 temporary code, with Fred N. Fish's comment that it's temporary,
4486 has been in Emacs since at least 1992!
4487 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
4488 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
4489 * syssignal.h (croak): Remove decl.
4490 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
4491 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
4492 now that we're termios-only.
4493 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
4494 * term.c (dissociate_if_controlling_tty): Use #error rather than
4497 Work around GCC and GNOME bugs when --enable-gcc-warnings.
4498 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
4499 to work around GNOME bug 683906.
4500 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
4501 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
4502 This works around GCC bug 54561.
4504 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4506 More fixes for 'volatile' and setjmp/longjmp.
4507 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
4508 * image.c (struct png_load_context) [HAVE_PNG]: New type.
4509 (png_load_body) [HAVE_PNG]:
4510 (jpeg_load_body) [HAVE_JPEG]:
4511 New function, with most of the old parent function's body.
4512 (png_load) [HAVE_PNG]:
4513 (jpeg_load) [HAVE_JPEG]:
4514 Invoke the new function, to avoid longjmp munging our locals.
4515 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
4516 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
4517 longjmp is passed 2, as the C standard doesn't guarantee this.
4518 Instead, store the failure code into mgr->failure_code.
4520 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4522 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
4523 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
4524 (syms_of_keyboard): Remove support for unread-command-char.
4526 2012-09-12 Eli Zaretskii <eliz@gnu.org>
4528 * w32proc.c (sys_kill): If PID is our process ID and the signal is
4529 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
4530 violation. (Bug#12426)
4532 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4534 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
4536 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4538 * eval.c: Add `inhibit-debugger'.
4539 (Qinhibit_debugger): New symbol.
4540 (call_debugger): Bind it instead of Qdebug_on_error.
4541 (maybe_call_debugger): Test Vinhibit_debugger.
4542 (syms_of_eval): Define inhibit-debugger.
4543 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
4544 (syms_of_xdisp): Remove inhibit-debug-on-message.
4546 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4548 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
4549 If a nonvolatile local variable is written before a _longjmp to
4550 the frame containing the variable, and is read after the _longjmp,
4551 the value read is indeterminate. Some local variables of type
4552 'struct handler' and 'struct catchtag' are used in this way, so
4553 mark each of their slots as volatile if the slot can be set before
4554 _longjmp and read afterwards.
4555 * lisp.h (struct handler): var and chosen_clause are now volatile.
4556 (struct catchtag): val, next, and pdlcount are now volatile.
4558 * bidi.c (bidi_push_it, bidi_pop_it):
4559 * fns.c (copy_hash_table):
4560 * image.c (define_image_type):
4561 * keyboard.c (kbd_buffer_store_event_hold):
4562 * process.c (Fprocess_send_eof):
4563 * xfaces.c (x_create_gc) [HAVE_NS]:
4564 * xgselect.c (xg_select):
4565 Prefer assignment to memcpy when either will do.
4567 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
4568 Use pointer-to-a-pointer to simplify and avoid a NILP check each
4569 time an item is removed. No need to mark this function 'inline';
4570 the compiler knows better than we do.
4572 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
4574 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
4575 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
4576 to change_frame_size (Bug#12388).
4577 (windowDidResize:): Pass YES to updateFrameSize.
4579 * nsterm.h: Add delay parameter to updateFrameSize.
4581 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4583 Discard killed buffers from deleted window and frame objects.
4584 This reduces an amount of references to killed buffers and
4585 helps GC to reclaim them faster.
4586 * alloc.c (discard_killed_buffers): New function.
4587 (mark_object): Use it for deleted windows and frames.
4588 (mark_object): If symbol's value is set up for a killed buffer
4589 or deleted frame, restore its global binding.
4590 * data.c (swap_in_global_binding): Add GC notice.
4591 (swap_in_symval_forwarding): Use convenient set_blv_where.
4592 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
4593 * window.h: ... to here.
4595 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4597 Convenient macro to check whether the buffer is live.
4598 * buffer.h (BUFFER_LIVE_P): New macro.
4599 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
4600 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
4602 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4604 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
4605 composition cases (Bug#12364).
4607 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
4608 overhang of succeeding glyphs overlapping box cursor.
4610 * w32term.c (x_draw_glyph_string): Likewise.
4612 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4614 Simplify, document, and port floating-point (Bug#12381).
4615 The porting part of this patch fixes bugs on non-IEEE platforms
4616 with frexp, ldexp, logb.
4617 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
4619 * floatfns.c: Simplify discussion of functions that Emacs doesn't
4620 support, by removing commented-out code and briefly listing the
4621 C89 functions excluded. The commented-out stuff was confusing
4622 maintenance, e.g., we thought we needed cbrt but it was commented out.
4623 (logb): Remove decl; no longer needed.
4624 (isfinite): New macro, if not already supplied.
4625 (isnan): Don't replace any existing macro.
4626 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
4627 are present on all C89 platforms.
4628 (Ffrexp): Do not special-case zero, as frexp does the right thing
4630 (Flogb): Do not use logb, as it doesn't have the desired meaning
4631 on hosts that use non-base-2 floating point. Instead, stick with
4632 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
4633 frexp, to avoid getting an unspecified result.
4635 * xdisp.c (Qinhibit_debug_on_message): Now static.
4637 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
4639 * nsterm.m (ns_update_begin): Set clip path to whole view by using
4640 NSBezierPath (Bug#12131).
4642 2012-09-10 Chong Yidong <cyd@gnu.org>
4644 * fns.c (Fdelq, Fdelete): Doc fix.
4646 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
4648 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
4649 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
4651 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
4653 * lisp.h (make_lisp_ptr): New macro to replace XSET.
4654 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
4657 2012-09-09 Eli Zaretskii <eliz@gnu.org>
4659 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
4660 left fringe if the window has a left margin. This avoids leaving
4661 traces of the cursor because its leftmost pixel is not drawn over.
4663 * dispnew.c (update_window_line): When the left margin area of a
4664 screen line is updated, set the redraw_fringe_bitmaps_p flag of
4665 that screen line. (Bug#12277)
4667 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
4669 Assume C89 or later for math functions (Bug#12381).
4670 This simplifies the code, and makes it a bit smaller and faster,
4671 and (most important) makes it easier to clean up signal handling
4672 since we can stop worring about floating-point exceptions in
4673 library code. That was a problem before C89, but the problem
4674 went away many years ago on all practical Emacs targets.
4675 * data.c, image.c, lread.c, print.c:
4676 Don't include <math.h>; no longer needed.
4677 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
4678 might be autoconfigured, as that never happens.
4680 * doprnt.c (DBL_MAX_10_EXP):
4681 * print.c (DBL_DIG):
4682 Remove. C89 or later always defines these.
4683 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
4684 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
4685 (arith_error, domain_error, domain_error2):
4686 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
4687 no longer needed -- we simply return what C returns. All uses removed.
4688 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
4690 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
4691 Remove. All uses expanded, as these macros are no longer used
4692 more than once and are now more trouble than they're worth.
4693 (Ftan): Use tan, not sin / cos.
4694 (Flogb): Assume C89 frexp.
4695 (fmod_float): Assume C89 fmod.
4696 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
4697 (init_floatfns): Remove. All uses removed.
4699 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4701 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
4702 compositeToPoint for OSX < 10.6 (Bug#12390).
4704 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
4706 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
4707 This produces more-accurate results.
4709 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4711 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
4712 changes (Bug#12088).
4714 2012-09-08 Chong Yidong <cyd@gnu.org>
4716 * syntax.c (Fstring_to_syntax): Doc fix.
4718 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4720 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
4721 in the internal border.
4722 (x_set_window_size): Remove static variables and their usage.
4723 (ns_redraw_scroll_bars): Fix NSTRACE arg.
4724 (ns_after_update_window_line, ns_draw_fringe_bitmap):
4725 Remove fringe/internal border adjustment (Bug#11052).
4726 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
4727 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
4728 (ns_fix_rect_ibw): Remove.
4729 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
4730 (ns_dumpglyphs_box_or_relief): Ditto.
4731 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
4733 (ns_dumpglyphs_image): Ditto.
4734 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
4736 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
4737 their usage. Add fringe_extended_p and its use as in other terms.
4738 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
4739 scroll bar was removed.
4740 (updateFrameSize): New function.
4741 (windowDidResize): Move code to updateFrameSize and call it.
4743 * nsterm.h (EmacsView): Add updateFrameSize.
4745 2012-09-07 Chong Yidong <cyd@gnu.org>
4747 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
4749 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
4751 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4753 More signal-handler cleanup (Bug#12327).
4754 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
4755 Problem introduced when merging patches. Noted by Eli Zaretskii in
4756 <http://bugs.gnu.org/12327#67>.
4757 * floatfns.c: Comment fix.
4758 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
4759 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
4760 and anyway the declaration is harmless even if SIGDANGER is not defined.
4761 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
4762 defined BROKEN_FIONREAD). systty.h formerly did this, but other
4763 source files not surprisingly expected syssignal.h to define, or
4764 not define, SIGIO, and it's cleaner to do it that way, for consistency.
4765 Include <sys/ioctl.h>, for FIONREAD.
4766 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
4767 This eliminates a problem whereby other files mysteriously had
4768 to include "syssignal.h" before including "systty.h" if they
4769 wanted to use "#ifdef SIGIO".
4771 2012-09-07 Eli Zaretskii <eliz@gnu.org>
4773 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
4775 * w32.c (sigemptyset): Empty the set.
4776 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
4778 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
4780 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
4782 * alloc.c (mark_buffer): Revert unsafe marking optimization.
4783 (mark_object): Likewise for frame objects.
4785 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4787 * syssignal.h (handle_on_main_thread): Always declare,
4788 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
4789 This ports to platforms without HAVE_PTHREAD.
4791 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4793 Signal-handler cleanup (Bug#12327).
4794 Emacs's signal handlers were written in the old 4.2BSD style with
4795 sigblock and sigmask and so forth, and this led to some
4796 inefficiencies and confusion. Rewrite these to use
4797 pthread_sigmask etc. without copying signal sets around. Also,
4798 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
4799 'signal', and instead use functions that do not attempt to take
4800 over the system name space. This patch causes Emacs's text
4801 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
4802 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
4803 Do not include <signal.h> or "syssignal.h", as these
4804 modules do not use signals.
4805 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
4806 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
4807 Do not include <signal.h>, as "syssignal.h" does that for us now.
4808 * atimer.c (sigmask_atimers): New function.
4809 (block_atimers, unblock_atimers): New functions,
4810 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
4812 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
4813 no longer needed here.
4814 * emacs.c (main): Inspect existing signal handler with sigaction,
4815 so that there's no need to block and unblock SIGHUP.
4816 * sysdep.c (struct save_signal): New member 'action', replacing
4817 old member 'handler'.
4818 (save_signal_handlers, restore_signal_handlers):
4819 Use sigaction instead of 'signal' to save and restore.
4820 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
4821 New function. All users of 'signal' modified to use set_sighandler
4822 if they're writeonly, and to use sys_signal if they're read+write.
4823 (emacs_sigaction_init, forwarded_signal): New functions.
4824 (sys_signal): Remove. All uses replaced by calls to sigaction
4825 and emacs_sigaction_init, or by direct calls to 'signal'.
4826 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
4827 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
4828 all uses replaced by pthread_sigmask etc. calls.
4829 * syssignal.h: Include <signal.h>.
4830 (emacs_sigaction_init, forwarded_signal): New decls.
4831 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
4832 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
4833 (sigmask, sys_sigmask): Remove; no longer needed.
4834 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
4835 (sigblock, sigunblock, sigfree):
4836 (sigsetmask) [!defined sigsetmask]:
4837 Remove. All uses replaced by pthread_sigmask.
4838 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
4839 no longer need to be replaced, and its typical old uses
4840 are now done via emacs_sigaction_init and sigaction.
4841 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
4842 (sys_sigdel): Remove; unused.
4843 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
4845 2012-09-06 Eli Zaretskii <eliz@gnu.org>
4847 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
4848 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
4850 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4852 Explicitly mark buffer_defaults and buffer_local_symbols.
4853 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
4854 mark_local_symbols here.
4855 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
4856 since special buffers aren't marked here any more.
4857 (allocate_buffer): Chain new buffer with all_buffers here...
4858 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
4860 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
4861 (syms_of_buffer): Remove staticpro of the above.
4862 (init_buffer_once): Set names for buffer_defaults and
4863 buffer_local_symbols.
4865 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4867 Use bool for booleans in font-related modules.
4868 * font.c (font_intern_prop, font_style_to_value)
4869 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
4870 (generate_otf_features, font_check_otf_features, font_check_otf)
4871 (font_match_p, font_list_entities, font_at):
4872 * fontset.c (fontset_id_valid_p, reorder_font_vector
4873 (fontset_find_font, Fset_fontset_font)
4874 (face_suitable_for_char_p) [0]:
4875 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
4876 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
4877 (m17n_flt_initialized, ftfont_shape_by_flt):
4878 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
4879 * nsfont.m (nsfont_draw):
4880 * w32font.c (w32font_draw):
4881 * w32term.c (x_draw_glyphless_glyph_string_foreground):
4882 Use bool for booleans.
4883 * font.h: Adjust to above API changes.
4884 (struct font, struct font_driver, struct font_driver_list):
4885 Use bool for booleans.
4886 (struct font): Remove useless member encoding_type.
4888 * fontset.c, xftfont.c: Omit unnecessary static decls.
4890 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4892 * alloc.c (mark_object): Revert window marking code
4893 since it's unsafe for the Fset_window_configuration.
4895 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4897 Fix race conditions with signal handlers and errno (Bug#12327).
4898 Be more systematic about preserving errno whenever a signal
4899 handler returns, even if it's not in the main thread. Do this by
4900 renaming signal handlers to distinguish between signal delivery
4901 and signal handling. All uses changed.
4902 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
4903 * data.c (deliver_arith_signal): Rename from arith_error.
4904 * dispnew.c (deliver_window_change_signal): Rename from
4905 window_change_signal.
4906 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
4907 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
4908 * keyboard.c (deliver_input_available_signal): Rename from
4909 input_available_signal.
4910 (deliver_user_signal): Rename from handle_user_signal.
4911 (deliver_interrupt_signal): Rename from interrupt_signal.
4912 * process.c (deliver_pipe_signal): Rename from send_process_trap.
4913 (deliver_child_signal): Rename from sigchld_handler.
4914 * atimer.c (handle_alarm_signal):
4915 * data.c (handle_arith_signal):
4916 * dispnew.c (handle_window_change_signal):
4917 * emacs.c (handle_fatal_signal, handle_danger_signal):
4918 * keyboard.c (handle_input_available_signal):
4919 * keyboard.c (handle_user_signal, handle_interrupt_signal):
4920 * process.c (handle_pipe_signal, handle_child_signal):
4921 New functions, with the actual signal-handling code taken from the
4922 original respective signal handlers, sans the sporadic attempts to
4923 preserve errno, since that's now done by handle_on_main_thread.
4924 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
4925 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
4926 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4928 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4929 Move initialization of main_thread to sysdep.c's init_signals.
4930 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
4931 our usage, and simplifies the mainline code.
4932 (record_child_status_change): New static function, as a helper
4933 for handle_child_signal, and with most of the old child handler's
4935 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
4936 (handle_child_signal): Use the above.
4937 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4938 Moved here from emacs.c.
4939 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
4940 code moved here from emacs.c's main function.
4941 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
4942 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
4943 This lets callers save and restore errno properly.
4945 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4947 Remove redundant or unused things here and there.
4948 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
4949 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
4950 * editfns.c (Fcompare_buffer_substrings): Likewise.
4951 * frame.h (struct terminal, struct font_driver_list):
4952 Remove redundant declarations.
4953 * window.h (Qleft, Qright): Likewise.
4955 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4957 Do not mark objects from deleted buffers, windows and frames.
4958 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
4959 (mark_object): Likewise for windows and frames.
4961 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4963 * alloc.c (valid_lisp_object_p): Treat killed buffers,
4964 buffer_defaults and buffer_local_symbols as valid objects.
4965 Return special value to denote them.
4967 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4969 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
4970 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
4971 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
4972 (file_name_absolute_p, Fsubstitute_in_file_name):
4973 (check_executable, check_writable, Ffile_accessible_directory_p)

4975 (Finsert_file_contents, choose_write_coding_system)
4976 (Fwrite_region, build_annotations, a_write, e_write)
4978 * filelock.c (boot_time_initialized, get_boot_time)
4979 (get_boot_time_1, lock_file_1, within_one_second):
4980 * floatfns.c (in_float):
4981 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
4982 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
4983 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
4984 * lisp.h (struct Lisp_Hash_Table.cmpfn):
4985 * window.c (compare_window_configurations):
4986 Use bool for booleans.
4987 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
4988 (Fdefault_file_modes): Now mode_t, not int, for modes.
4989 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
4990 (internal_delete_file): Now returns void, not a (boolean) int,
4991 since nobody was looking at the return value.
4992 * lisp.h, window.h: Adjust to above API changes.
4994 * xdisp.c (set_message): Simplify and reindent last change.
4996 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
4998 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
5000 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
5002 * eval.c (call_debugger): Make the function non-static so that we
5003 can call it from set_message.
5005 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
5006 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
5008 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5010 Give more-useful info on a fatal error (Bug#12328).
5011 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
5012 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
5013 of doing the work ourselves.
5014 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
5015 do most of the work.
5016 (fatal_error_backtrace): New function, taken from the guts
5017 of the old fatal_error_signal, but with a new option to output
5019 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
5020 info about the signal than just its number.
5021 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
5022 * sysdep.c: Include <execinfo.h>
5023 (emacs_backtrace): New function, taken partly from the previous
5024 code of the 'die' function.
5025 (emacs_abort): Call fatal_error_backtrace rather than abort.
5027 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
5029 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
5030 eager (load-time) macro-expansion.
5031 * lisp.mk (lisp): Add macroexp.

5035 Simplify redefinition of 'abort' (Bug#12316).
5036 Do not try to redefine the 'abort' function. Instead, redo
5037 the code so that it calls 'emacs_abort' rather than 'abort'.
5038 This removes the need for the NO_ABORT configure-time macro
5039 and makes it easier to change the abort code to do a backtrace.
5040 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
5041 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
5042 Remove; sysdep.c's emacs_abort now takes its place.
5043 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
5044 'abort' changed to use 'emacs_abort'.
5045 * msdos.c (dos_abort) [defined abort]: Remove; not used.
5046 (abort) [!defined abort]: Rename to ...
5047 (emacs_abort): ... new name.
5048 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
5049 the place of the old 'abort' in emacs.c.
5050 * w32.c, w32fns.c (abort): Do not #undef.
5051 * w32.c (emacs_abort): Rename from w32_abort.
5053 2012-09-04 Eli Zaretskii <eliz@gnu.org>
5055 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
5056 offsets[j].dv, since the y axis of the screen coordinates points
5057 down, while the y axis of the font definition coordinates points
5058 up. This fixes display of Arabic diacritics such as KASRA and
5059 KASRATAN. (Bug#11860)
5061 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5063 Be more systematic about _setjmp vs setjmp.
5064 * alloc.c (test_setjmp, mark_stack):
5065 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
5066 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
5067 (png_load, my_error_exit, jpeg_load):
5068 * process.c (send_process_trap, send_process):
5069 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
5070 The underscored versions are up to 30x faster on some hosts.
5071 Formerly, the code used setjmp+longjmp sometimes and
5072 _setjmp+_longjmp at other times, with no particular reason to
5073 prefer setjmp+longjmp.
5075 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
5077 Fix minor problem found by static checking.
5078 * buffer.c (Fdelete_all_overlays): Return nil.
5080 2012-09-03 Martin Rudalics <rudalics@gmx.at>
5082 * buffer.c (Fdelete_all_overlays): New function.
5084 2012-09-03 Chong Yidong <cyd@gnu.org>
5086 * gtkutil.c: Add extern decl for Qxft.
5088 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

5103 * eval.c (interactive_p): Omit always-true boolean argument
5104 EXCLUDE_SUBRS_P. All callers changed.
5105 * dispextern.h, lisp.h: Reflect above API changes.
5106 * firstfile.c (dummy): Use the address of 'main', whose signature
5107 won't change, instead of the address of 'initialize', whose
5108 signature just changed from int to bool.
5109 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
5110 * msdos.c (fatal_error_in_progress): ... from here.
5111 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
5113 (redisplay_internal, unwind_redisplay): Simply clear
5114 REDISPLAYING_P when unwinding, instead of saving its previous,
5115 always-false value and then restoring it.
5117 Clean up some extern decls.
5118 Mostly, this hoists extern decls out of .c files and into .h files.
5119 That way, we're more likely to catch errors if the interfaces change.
5120 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
5121 declare xg_mark_data.
5122 * dispextern.h (x_frame_parm_handlers):
5124 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)

5138 * widget.c (free_frame_faces):
5139 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
5140 * xfont.c (x_clear_errors):
5141 * xterm.c (x_frame_parm_handlers):
5142 Remove now-redundant extern decls.
5143 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
5144 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
5146 * xfaces.c: Remove unnecessary static decls.
5147 * xterm.c (updating_frame): Remove decl of nonexistent object.
5149 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
5150 when building globals.h, as the objects that are not built on
5151 this host are not needed to compile C files on this host.
5153 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
5155 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

5183 * keyboard.c (decode_timer):
5184 Use bool for boolean.
5185 * intervals.h, lisp.h, systime.h: Reflect above API changes.

5193 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
5195 * makefile.w32-in (CCL_H, W32FONT_H): New macros.

5203 2012-09-01 Eli Zaretskii <eliz@gnu.org>
5205 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
5206 more than one grapheme cluster passed to the shaper: compute the
5207 offset adjustment values separately for each cluster. (Bug#11860)
5209 * image.c: Restore mistakenly removed inclusion of w32.h. Without
5210 it, GCC doesn't see prototypes of w32_delayed_load, and complains
5211 about implicit conversions from integer to pointer.
5213 2012-09-01 Daniel Colascione <dancol@dancol.org>
5215 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
5216 system used too early.
5218 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
5220 Better seed support for (random).

5269 window system declarations.
5271 * frame.h: Move common functions here: set_frame_menubar,
5272 x_set_window_size, x_sync, x_get_focus_frame,
5273 x_set_mouse_position, x_set_mouse_pixel_position,
5274 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

5301 * lisp.h (mark_ttys): Remove prototype.
5302 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
5303 to mark_ttys because all possible values of 'top_frame' slot are
5304 the frames which are reachable from Vframe_list.
5305 * term.c (mark_ttys): Remove.
5306 (init_tty): Safely initialize 'top_frame' slot with Qnil.
5308 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>

5335 * lread.c (init_lread): For out-of-tree builds, only add the
5336 source directory's site-lisp dir to the load-path if it exists,
5337 consistent with in-tree builds. (Bug#12302)
5339 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

5358 Handle click on close button as quit.
5360 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
5361 Add window_closed and button_values. Add void as return value for
5362 add(Button|String|Split). addButton takes int instead of Lisp_Object.
5363 Add process_dialog as new member.
5365 2012-08-28 Eli Zaretskii <eliz@gnu.org>
5367 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it

5497 (code_convert_string, code_convert_string_norecord)
5498 (Fset_coding_system_priority):
5499 * fileio.c (Finsert_file_contents):
5500 Use bool for booleans.
5501 * coding.h, lisp.h: Reflect above API changes.
5502 * coding.c: Remove unnecessary static function decls.
5503 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
5504 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
5505 not a boolean 'int', since callers never look at the return value.
5506 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
5507 * coding.h (decoding_buffer_size, encoding_buffer_size)
5508 (emacs_mule_string_char): Remove unused extern decls.
5509 (struct iso_2022_spec, struct coding_system):
5510 Use 'unsigned int : 1' for boolean fields, since there's more than one.
5511 (struct emacs_mule_spec): Remove unused field 'full_support'.
5512 All initializations removed.
5513 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
5515 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
5517 Fix spare memory change (Bug#12286).
5518 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
5519 (valid_lisp_object_p): Likewise.
5521 2012-08-27 Martin Rudalics <rudalics@gmx.at>
5523 * window.c (Fset_window_configuration): Record any window's old
5524 buffer if it's replaced (see Bug#8789). If the new current
5525 buffer doesn't appear in the selected window, go to its old
5528 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
5530 Special MEM_TYPE_SPARE to denote reserved memory.
5531 * alloc.c (enum mem_type): New memory type.
5532 (refill_memory_reserve): Use new type for spare memory.
5533 This prevents live_cons_p and live_string_p from incorrect
5534 detection of uninitialized objects from spare memory as live.
5536 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
5539 * Makefile.in (.PHONY): versioclean -> versionclean.
5541 Remove unused external symbols.
5542 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
5543 * window.c (Qwindow_valid_p, decode_valid_window):
5544 Now static, not extern.
5545 * data.c (Qinterval): Remove; unused.
5546 (syms_of_data): Do not define 'interval'.
5547 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
5548 * window.h (decode_valid_window):
5551 * character.c, charset.c, chartab.c: Use bool for booleans.
5552 * character.c (lisp_string_width, string_count_byte8)
5553 (string_escape_byte8):
5554 * charset.c (charset_map_loaded, load_charset_map, read_hex):

5557 (Fdeclare_equiv_charset, find_charsets_in_text)

5560 (sub_char_table_set, sub_char_table_set_range)
5561 (char_table_set_range, optimize_sub_char_table)
5562 (map_sub_char_table):
5563 Use bool for boolean.
5564 * character.c (str_to_unibyte): Omit last boolean argument; it was
5565 always 0. All callers changed.
5566 * character.h, charset.h: Adjust to match previous changes.
5567 * character.h (char_printable_p): Remove decl of nonexistent function.
5568 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
5569 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
5570 are all boolean, so make them single-bit bitfields.
5572 * lisp.h (ASET): Remove attempt to detect side effects.
5573 It was meant to be temporary and it often doesn't work,
5574 because when IDX has side effects the behavior of IDX==IDX
5575 is undefined. See Stefan Monnier in
5576 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
5578 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
5580 * lisp.h (functionp): New function (extracted from Ffunctionp).
5581 (FUNCTIONP): Use it.
5582 * eval.c (Ffunctionp): Use it.
5584 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
5586 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
5587 as that's faster and simpler than static storage. Don't bother
5588 with the g_main_context_query overhead if g_main_context_pending
5589 says no events are pending.
5590 (gfds, gfds_size): Remove these static vars.
5591 (xgselect_initialize): Remove; no longer needed.
5592 All uses and decls removed.
5594 * emacs.c (fatal_error_signal_hook): Remove.
5595 All uses removed. This leftover from old code was always 0.
5597 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
5598 * casefiddle.c (casify_object, casify_region):
5599 * casetab.c (set_case_table):
5600 * category.c, category.h (word_boundary_p):
5601 * category.h (CHAR_HAS_CATEGORY):
5602 Use bool for booleans, instead of int.
5604 2012-08-25 Eli Zaretskii <eliz@gnu.org>
5606 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
5608 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
5610 On assertion failure, print backtrace if available.
5611 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
5612 (die) [ENABLE_CHECKING]: Print a backtrace if available.
5613 * Makefile.in (LIB_EXECINFO): New macro.
5616 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
5617 * bytecode.c (exec_byte_code):
5618 * callint.c (check_mark, Fcall_interactively):
5619 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
5620 (getenv_internal, sync_process_alive, call_process_exited):
5621 * lisp.h (USE_SAFE_ALLOCA):
5622 Use bool for booleans, instead of int.
5623 * lisp.h, process.h: Adjust prototypes to match above changes.
5624 * callint.c (Fcall_interactively): Don't assume the mark's
5625 offset fits in 'int'.
5627 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
5629 * buffer.c, buffer.h: Use bool for boolean.
5630 * buffer.c (reset_buffer_local_variables)
5631 (buffer_lisp_local_variables, Fset_buffer_modified_p)
5632 (Frestore_buffer_modified_p, Fset_buffer_multibyte):

5634 (overlay_touches_p, overlay_strings, Foverlay_put)
5635 (report_overlay_modification, call_overlay_mod_hooks):
5636 (mmap_enlarge, mmap_set_vars):
5637 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
5638 Use bool for booleans, instead of int.
5639 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
5640 since the 1-or-0 return value is always ignored anyway.
5641 (mmap_initialized_p):
5642 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
5643 * buffer.h, lisp.h: Adjust prototypes to match above changes.
5645 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5647 * bidi.c: Use bool for boolean.
5648 This is a bit more readable, and makes the text segment of bidi.o
5649 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
5650 Presumably it's faster too.
5651 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
5653 (bidi_cache_find_level_change, bidi_cache_iterator_state)
5654 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
5655 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
5656 (bidi_explicit_dir_char, bidi_level_of_next_char)
5657 (bidi_find_other_level_edge, bidi_move_to_visually_next):
5658 Use bool for booleans, instead of int.
5659 * dispextern.h (bidi_init_it, bidi_paragraph_init)
5660 (bidi_unshelve_cache): Adjust decls to match code.
5662 2012-08-23 Martin Rudalics <rudalics@gmx.at>
5664 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
5667 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5669 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
5670 * atimer.h: Include <stdbool.h>.
5672 2012-08-22 Dan Nicolaescu <dann@gnu.org>
5674 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
5675 compile time tests instead of run time tests on systems that do
5677 (FRAME_MAC_P): Remove leftover from deleted code.
5678 * frame.c (syms_of_frame): Remove leftover from deleted code.
5680 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
5682 * nsterm.m (insertText:): Don't clear modifiers if code is space.
5684 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
5686 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
5687 Otherwise, the compiler complains about (A?B:C) where B is void
5688 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
5689 (fontset_add): Return void, for FONTSET_ADD.
5691 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5693 * alloc.c: Use bool for booleans.
5694 (gc_in_progress, abort_on_gc)
5695 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5696 (dont_register_blocks) [GC_MALLOC_CHECK]:
5697 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
5698 (check_string_bytes, make_specified_string, memory_full)
5699 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
5700 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
5701 (mark_stack, valid_pointer_p, make_pure_string)
5702 (Fgarbage_collect, survives_gc_p, gc_sweep):
5703 Use bool for booleans, instead of int.
5704 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5705 Remove unused local.
5706 * alloc.c (PURE_POINTER_P):
5707 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
5708 * editfns.c (Fformat):
5709 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
5711 * fns.c (sweep_weak_table):
5712 * lisp.h (suppress_checking, push_message, survives_gc_p)
5713 (make_pure_string, gc_in_progress, abort_on_gc):
5714 * lread.c (readchar, read1):
5715 * print.c (Fprin1_to_string):
5716 * xdisp.c (push_message):
5717 Use bool for booleans affected directly or indirectly by
5720 Make recently-introduced setters macros.
5721 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
5722 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
5723 (set_fontset_default, set_fontset_fallback): Rename from their
5724 upper-case counterparts, and make them functions rather than macros.
5725 This is more consistent with the other recently-introduced setters.
5726 These don't need to be inline, since they're local.
5728 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
5730 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
5731 the loop (Bug#12247).
5733 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5735 * lisp.h (vcopy): Use memcpy rather than our own loop.
5736 This fixes a performance regression introduced by the recent
5737 addition of vcopy. This means 'vcopy' will need to be modified
5738 for a copying collector, but that's OK. Also, tighten the
5739 checking in the assertion.
5741 2012-08-21 Eli Zaretskii <eliz@gnu.org>
5743 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
5744 components for RTL text (Bug#11860). Adjust X-OFFSET of each
5745 non-base glyph for the width of the base character, according to
5746 what x_draw_composite_glyph_string_foreground expects.
5747 Generate WADJUST value according to composition_gstring_width's
5748 expectations, to produce correct width of the composed character.
5749 Reverse the sign of the DU offset produced by ScriptPlace.
5751 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5753 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
5755 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
5757 Avoid direct writes to contents member of struct Lisp_Vector.
5758 * lisp.h (vcopy): New function to copy data into vector.
5759 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
5760 * fns.c (Ffillarray): Use ASET.
5761 * keyboard.c (timer_check_2): Use AREF and ASET.
5762 (append_tool_bar_item, Frecent_keys): Use vcopy.
5763 * lread.c (read_vector): Use ASET.
5764 * msdos.c (Frecent_doskeys): Use vcopy.
5765 * xface.c (Finternal_copy_lisp_face): Use vcopy.
5766 (Finternal_merge_in_global_face): Use ASET and vcopy.
5767 * xfont.c (xfont_list_pattern): Likewise.
5769 2012-08-21 Martin Rudalics <rudalics@gmx.at>
5771 * window.c (Fwindow_point): For the selected window always return
5772 the position of its buffer's point.
5773 (Fset_window_point): For the selected window always go in its
5774 buffer to the specified position.
5776 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
5778 Setter macros for fontsets.
5779 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
5780 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
5781 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
5784 2012-08-20 Glenn Morris <rgm@gnu.org>
5786 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
5787 Don't assume that `ln -f' works.
5789 2012-08-20 Eli Zaretskii <eliz@gnu.org>
5791 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
5792 and later about non-assignments with no effect. See discussion at
5793 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
5796 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5798 Inline setter functions for Lisp_Objects slots of struct specbinding.
5799 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
5802 2012-08-20 Martin Rudalics <rudalics@gmx.at>
5804 * window.c (select_window): Always make selected window's buffer
5807 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5809 Use AREF and ASET for docstrings of category tables.
5810 * category.h (CATEGORY_DOCSTRING): Use AREF.
5811 (SET_CATEGORY_DOCSTRING): Use ASET.
5812 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
5814 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5816 Inline setter functions for hash table members.
5817 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
5818 (set_hash_hash, set_hash_index): Rename with _slot suffix.
5819 (set_hash_key_and_value, set_hash_index, set_hash_next)
5820 (set_hash_hash): New functions.
5821 * charset.c, fns.c: Adjust users.
5823 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5825 Inline getter and setter functions for per-buffer values.
5826 * buffer.h (per_buffer_default, set_per_buffer_default)
5827 (per_buffer_value, set_per_buffer_value): New functions.
5828 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
5829 * buffer.c, data.c: Adjust users.
5831 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
5833 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
5835 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
5837 Rely on <config.h> + <unistd.h> to declare 'environ',
5838 as gnulib does this if the system doesn't.
5839 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
5840 Remove declaration. MS-Windows declares it on stdlib.h which is
5841 included by conf_post.h.
5842 * emacs.c (environ) [DOUG_LEA_MALLOC]:
5843 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
5844 * vm-limit.c: Include <unistd.h>, for 'environ'.
5846 * unexaix.c, unexcoff.c: Include "mem-limits.h".
5847 (start_of_data): Remove decl; mem-limits.h provides it.
5849 * xdisp.c (handle_invisible_prop): Make it a bit faster
5850 and avoid a gcc -Wmaybe-uninitialized diagnostic.
5852 2012-08-19 Chong Yidong <cyd@gnu.org>
5854 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
5857 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
5859 * .gdbinit: Use call instead of set when calling a function in the
5862 * data.c (set_internal): Don't use set_blv_found.
5863 (Fkill_local_variable): Likewise.
5865 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
5867 * nsfont.m (ns_ascii_average_width): Ensure the string
5868 ascii_printable is initialized with a null-terminated character
5869 array. Otherwise, it can contain undesired extra characters.
5871 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
5873 port new setting code to Sun C 5.8 2005/10/13
5874 * chartab.c, lisp.h (char_table_set, char_table_set_range):
5875 Return void, not Lisp_Object. Otherwise, the compiler
5876 complains about (A?B:C) where B is void and C is Lisp_Object
5877 when compiling CHAR_TABLE_SET, due to the recent change to
5878 the API of sub_char_table_set_contents.
5880 2012-08-18 Chong Yidong <cyd@gnu.org>
5882 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
5883 for the string case (Bug#3874).
5885 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
5887 * buffer.h (BSET): Remove (Bug#12215).
5888 Replace all uses with calls to new setter functions.

6820 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when

6822 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
6823 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
6824 since it's used in non-static inline functions now.
6826 * xfaces.c (face_at_buffer_position, face_for_overlay_string):

6878 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
6879 This how ASET and AREF are supposed to work, and makes
6880 it easier to think about future improvements. See
6881 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.

7264 (w32_kbd_patch_key, key_event): Use the codepage returned by
7265 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.
7266 (key_event): use uChar.UnicodeChar only if
7267 w32_console_unicode_input is non-zero.

7297 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
7298 enumeration constants, as PURE and HEAP are too general, and clash
7299 with other headers and sources, such as gmalloc.c and the
7300 MS-Windows system headers. All users changed.
7302 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
7304 Revert last save_excursion_save and save_excursion_restore changes.
7305 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

7318 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
7319 arms of an 'if', not using conditional expressions; otherwise GDB
7320 complains about the types in the unevaluated arm when the argument
7321 is an integer literal.
7322 (xgetint): Simplify expression.
7323 * alloc.c (gdb_make_enums_visible): New constant. This ports to
7324 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
7325 Zaretskii in <http://bugs.gnu.org/12036#13>.
7326 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
7327 needed now that we have gdb_make_enums_visible.
7328 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
7329 (enum enum_USE_LSB_TAG):
7330 New enum types, packaging up enums that need to be exported to GDB.

7349 * xfns.c (syms_of_xfns): Likewise.
7351 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>

7354 * lisp.h (struct Lisp_Excursion): New data type.
7355 (PVEC_EXCURSION): New pseudovector type.
7356 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
7357 to deal with it. Adjust comments.

7372 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
7373 emacs.c, as this is a more-suitable home. Had this been done earlier
7374 the fix for 12036 would have avoided some of the problems noted in
7375 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
7376 would have been more obvious.
7377 * emacs.c: Do not include <verify.h>; no longer needed.
7378 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
7379 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
7380 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

7385 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
7386 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
7387 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
7388 not be usable in #if. This simplifies things.
7390 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
7392 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

7397 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
7398 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
7399 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
7400 Adjust to changes in lisp.h and emacs.c, by using
7401 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
7402 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
7403 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
7404 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
7405 instead of gdb_valbits.
7406 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
7407 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
7408 instead of gdb_array_mark_flag.
7409 (xboolvector): Get size from $->size, not $->header.size.
7410 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
7411 (xreload, hook-run, hookpost-run): Remove.
7412 * emacs.c: Include <verify.h>.
7413 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
7414 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
7416 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
7417 (gdb_USE_LSB_TAG): New enum constants.
7418 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
7419 Also define these as enum constants, so they're visible to GDB.
7420 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
7421 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
7422 as constants, so they're visible to GDB.

7425 Now enum constants, not macros, so they're visible to GDB.
7426 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
7427 more convenient now. All uses changed.
7428 (VALMASK) [USE_LSB_TAG]: Also define in this case.

7438 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
7439 add argument, tune behavior, and adjust all callers.
7441 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
7443 Use typedef for EMACS_INT, EMACS_UINT.
7444 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
7445 than macros. This simplifies debugging in the usual case, since
7446 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
7447 and it allows expressions involving EMACS_INT casts.
7448 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
7450 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

7460 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
7462 Adjust buffer text indirection counters at the end of Fkill_buffer.
7463 * buffer.c (Fkill_buffer): Adjust indirection counters when the
7464 buffer is definitely dead. This should really fix an issue reported
7465 by Christoph Scholtes again. (Bug#12007).
7466 (init_buffer_once): Initialize indirection counters of
7467 buffer_defaults and buffer_local_symbols (for sanity and safety).
7469 2012-07-24 Eli Zaretskii <eliz@gnu.org>
7471 * xdisp.c (init_iterator): Don't compute dimensions of truncation
7472 and continuation glyphs on tooltip frames, leave them at zero.

7475 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
7477 Simplify copy_overlay.
7478 * buffer.c (copy_overlay): Simplify. Use build_marker.

7500 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
7502 Swap buffer text indirection counters in Fbuffer_swap_text.
7503 * buffer.c (Fbuffer_swap_text): Swap indirections too.
7504 This avoids crash reported by Christoph Scholtes at
7505 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
7507 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
7509 * nsmenu.m (Popdown_data): New struct.
7510 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
7512 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
7513 (initWithContentRect): Make imgView and contentView non-static
7514 and autorelease them. Also autorelease img and matrix (Bug#12005).
7515 (dealloc): Remove (Bug#12005).
7517 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
7519 Adjust consing_since_gc when objects are explicitly freed.

7532 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
7534 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
7535 as it's limited by the amount of memory, not by INT_MAX.
7537 2012-07-21 Eli Zaretskii <eliz@gnu.org>
7539 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
7540 in special-event-map. See the discussion at

7599 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
7600 of type Lisp_Object to avoid redundant calls to make_unibyte_string.

7621 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
7622 'for_each_per_buffer_object_at'.
7623 All uses changed. It's better to use upper-case for macros that
7624 cannot be implemented as functions, to give the reader a clue
7625 that they're special.

8193 * s/bsd-common.h, s/cygwin.h: No need to undefine INTERRUPT_INPUT,
8194 since nothing has defined it on these platforms.

8210 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
8211 function attribute, so we only use it if it exists in the
8214 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
8216 Avoid call to strlen in fast_c_string_match_ignore_case.

8263 * s/aix4-2.h (unix): Remove; no longer needed.
8265 EMACS_TIME simplification (Bug#11875).
8266 This replaces macros (which typically do not work in GDB)
8267 with functions, typedefs and enums, making the code easier to debug.
8268 The functional style also makes code easier to read and maintain.
8269 * systime.h: Include <sys/time.h> on all hosts, not just if
8270 WINDOWSNT, since 'struct timeval' is needed in general.
8271 (EMACS_TIME): Now a typedef, not a macro.
8272 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
8274 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

8278 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
8279 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
8280 which are not functions. All uses rewritten to use:
8281 (make_emacs_time): New function.
8282 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
8283 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
8284 not functions. All uses rewritten to use the following, respectively:
8285 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
8286 (add_emacs_time, sub_emacs_time): New functions.
8287 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
8288 * fileio.c (Fcopy_file):
8289 * xterm.c (XTflash): Get the current time closer to when it's used.
8290 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

8304 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
8305 (menu_separator_name_p):
8306 * nsmenu.m (ns_update_menubar):
8307 Prefer memcmp to strncmp when either will do.
8308 * nsterm.m: Include <ftoastr.h>.
8310 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
8311 Prefer snprintf to strncpy.
8312 * nsterm.m (ns_term_init):
8313 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
8314 * nsterm.m (ns_term_init):
8315 Avoid the need for strncpy, by using build_string or
8316 make_unibyte_string directly. Use dtoastr, not snprintf.
8317 * process.c (Fmake_network_process): Diagnose service names that
8318 are too long, rather than silently truncating them or creating
8319 non-null-terminated names.
8320 (Fnetwork_interface_info): Likewise, for interface names.
8321 * sysdep.c (system_process_attributes) [GNU_LINUX]:
8322 Prefer sprintf to strncat.
8323 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
8324 Prefer vsnprintf to vsprintf + strncpy.
8326 2012-07-10 Glenn Morris <rgm@gnu.org>
8328 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
8329 Clarify fallback case.
8331 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8333 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
8334 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
8335 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
8336 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
8337 where argument type is known to be a Lisp_Cons.
8339 2012-07-10 Tom Tromey <tromey@redhat.com>
8341 * bytecode.c (BYTE_CODE_THREADED): New macro.
8342 (BYTE_CODES): New macro. Replaces all old byte-code defines.

8349 Optimize pure C strings initialization.
8350 * lisp.h (make_pure_string): Fix prototype.
8351 (build_pure_c_string): New function, defined as static inline. This
8352 provides a better opportunity to optimize away calls to strlen when
8353 the function is called with compile-time constant argument.
8354 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
8355 argument, adjust users accordingly. Use build_pure_c_string where
8357 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
8358 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
8359 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
8361 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8363 Avoid calls to strlen in miscellaneous functions.
8364 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
8365 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
8366 * lread.c (openp): Likewise.
8368 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8370 Avoid calls to strlen in path processing functions.
8371 * fileio.c (file_name_as_directory): Add comment. Change to add
8372 srclen argument and return the length of result. Adjust users
8374 (directory_file_name): Fix comment. Change to add srclen argument,
8375 swap 1st and 2nd arguments to obey the common convention.
8376 Adjust users accordingly.
8377 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
8379 2012-07-10 Glenn Morris <rgm@gnu.org>
8381 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:

8384 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
8385 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
8386 * s/gnu.h (DATA_START): Move definitions to configure.
8388 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
8389 We include usg5-4-common.h, which defines them both.
8391 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
8392 O_RDONLY already includes it).
8394 Stop ns builds setting the EMACSLOADPATH environment variable.
8395 * nsterm.m (ns_load_path): Rename from ns_init_paths.
8396 Now it does not set EMACSLOADPATH, just returns the load-path string.
8397 * nsterm.h: Update accordingly.
8398 * lread.c [HAVE_NS]: Include nsterm.h.
8399 (init_lread) [HAVE_NS]: Use ns_load_path.
8400 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
8402 2012-07-09 Glenn Morris <rgm@gnu.org>
8404 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
8405 since the included bsd-common.h does so.
8407 Stop ns builds setting the EMACSPATH environment variable.
8408 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
8409 (ns_init_paths): Do not set EMACSPATH.
8410 * nsterm.h (ns_exec_path): Add it.
8411 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
8414 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
8416 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
8418 * process.c (wait_reading_process_output): 'waitchannels' was unset
8419 when read_kbd || !NILP (wait_for_cell); fix this.
8421 Add GCC-style 'const' attribute to functions that can use it.
8422 * character.h (char_resolve_modifier_mask):
8423 * keyboard.h (make_ctrl_char):
8424 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
8425 (init_character_once, next_almost_prime, init_fns, init_image)
8426 (flush_pending_output, init_sound):
8427 * mem-limits.h (start_of_data):
8428 * menu.h (finish_menu_items):

8431 Declare the dummy function with ATTRIBUTE_CONST.
8432 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
8433 Add decls with ATTRIBUTE_CONST.
8435 Minor improvements to make_formatted_string.
8436 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
8437 where int is good enough, as vsprintf returns an int.
8438 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
8440 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8442 Use make_formatted_string to avoid double length calculation.
8443 * lisp.h (make_formatted_string): New prototype.
8444 * alloc.c (make_formatted_string): New function.
8445 * buffer.c (Fgenerate_new_buffer_name): Use it.
8446 * dbusbind.c (syms_of_dbusbind): Likewise.
8447 * editfns.c (Fcurrent_time_zone): Likewise.
8448 * filelock.c (get_boot_time): Likewise.
8449 * frame.c (make_terminal_frame, set_term_frame_name)
8450 (x_report_frame_params): Likewise.
8451 * image.c (gs_load): Likewise.
8452 * minibuf.c (get_minibuffer): Likewise.
8453 * msdos.c (dos_set_window_size): Likewise.
8454 * process.c (make_process): Likewise.

8458 2012-07-09 Glenn Morris <rgm@gnu.org>
8460 Stop ns builds polluting the environment with EMACSDATA, EMACSDOC.
8461 * nsterm.m (ns_etc_directory): New function, split from ns_init_paths.
8462 (ns_init_paths): Do not set EMACSDATA, EMACSDOC.

8467 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8469 Move marker debugging code under MARKER_DEBUG.
8470 * marker.c (MARKER_DEBUG): Move marker debugging code under
8471 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
8472 for bootstrap with --enable-checking (~3x slowdown reported
8473 by Juanma Barranquero <lekktu@gmail.com>).
8474 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
8476 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
8478 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
8479 See <http://bugs.gnu.org/11825#29>.
8481 2012-07-08 Eli Zaretskii <eliz@gnu.org>
8483 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
8484 has no font, use the frame's font. (Bug#11813)
8485 (display_line): Add commentary about displaying truncation glyphs
8487 (produce_special_glyphs): Move here from term.c.
8489 * term.c (produce_special_glyphs): Move to xdisp.c.
8491 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
8494 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
8496 * xdisp.c (display_line): Avoid warning about implicit declaration
8499 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
8501 * lisp.h: Remove empty conditional.
8503 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8505 * lread.c (load_path_check): Now static.
8507 Fix some minor --with-ns problems found by static checking.
8508 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
8509 (x_set_font) [!HAVE_X_WINDOWS]:
8510 * image.c (xpm_load_image) [HAVE_NS]:
8511 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
8512 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
8513 Remove unused local.
8514 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
8515 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
8516 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
8517 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
8518 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
8519 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
8520 Fix pointer signedness problem.
8521 * xfaces.c (FRAME_X_FONT_TABLE):
8522 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
8524 2012-07-07 Glenn Morris <rgm@gnu.org>
8526 * lread.c (load_path_check): New function, split from init_lread.
8527 (init_lread): Reorganize. Motivation:
8528 If EMACSLOADPATH is set, check/warn about that rather than the
8529 defaults, which we are not going to use. Hence we can remove
8530 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
8531 Don't warn if site-lisp directories are missing.
8532 If not installed, start from a blank load-path, since
8533 PATH_LOADSEARCH refers to the eventual installation directories.
8535 2012-07-07 Eli Zaretskii <eliz@gnu.org>
8537 Support truncation and continuation glyphs on GUI frames, when
8538 fringes are disabled. (Bug#11832)
8539 * xdisp.c (init_iterator): Get dimensions of truncation and
8540 continuation glyphs even if on GUI frames.
8541 Adjust it->last_visible_x on GUI frames when the left or right fringes,
8542 or both, are absent.
8543 (start_display, move_it_in_display_line_to): Handle the case of a
8544 GUI frame without a fringe to display continuation or truncation
8546 (insert_left_trunc_glyphs): Support GUI frames: make sure
8547 truncation glyphs overwrite enough glyphs from the current line to
8548 have sufficient space in pixels.
8549 (display_line): Support truncation and continuation glyphs on GUI
8550 frames. If some spare pixels are left on the line after inserting
8551 the truncation glyphs, fill that space with a stretch glyph of a
8552 suitably computed width.
8554 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
8555 produce_glyphs, to support GUI sessions.
8557 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8559 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
8561 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
8563 Do not require float-time's arg to fit in time_t (Bug#11825).
8564 This works better on hosts where time_t is unsigned, and where
8565 float-time is applied to the (negative) difference between two times.
8566 * editfns.c (decode_time_components): Last arg is now double *,
8567 not int *, and means to store all the result as a double, without
8568 worrying about whether the seconds part fits in time_t.
8569 All callers changed.
8570 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
8571 All callers changed.

8617 * process.c: Avoid unnecessary calls to gettime.
8618 (wait_reading_process_output): Don't get the time of day
8619 when gobbling data immediately and not waiting, as there's no need
8620 for it in that case. This removes a FIXME.
8622 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
8624 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3

8635 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8637 Compile marker debugging code only if ENABLE_CHECKING is defined.
8638 * marker.c (byte_char_debug_check, count_markers):
8639 Use only if ENABLE_CHECKING is defined.
8640 (byte_debug_flag): Remove.
8641 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8642 Always call byte_char_debug_check if ENABLE_CHECKING is defined.

8684 Port to OpenBSD 5.1 amd64.
8685 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
8686 This is needed for OpenBSD, and should be harmless on all BSD systems.
8687 Also, include <sys/sysctl.h>, as it should be available on all
8688 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
8689 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
8690 use p_pid member, not kp_proc.pid.
8692 2012-07-06 Glenn Morris <rgm@gnu.org>
8694 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
8696 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

8707 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
8709 Omit needless casts involving void * pointers and allocation.
8710 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
8711 as the former is more robust if P's type is changed.
8712 Prefer xzalloc to xmalloc + memset 0.
8713 Simplify malloc-or-realloc to realloc.
8714 Don't worry about xmalloc returning a null pointer.
8715 Prefer xstrdup to xmalloc + strcpy.
8716 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
8718 * keyboard.c (apply_modifiers_uncached): Prefer local array to
8719 alloca of a constant.

8723 * xdisp.c (display_line): Fix horizontal pixel coordinates when
8724 hscroll is larger than the line width. Fixes long and futile
8725 looping inside extend_face_to_end_of_line (on a TTY) producing
8726 glyphs that are not needed and thrown away.
8728 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>

8744 followed by gtk_box_set_homogeneous (Bug#11768).
8745 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
8746 (update_theme_scrollbar_width, xg_create_scroll_bar):
8747 Use gtk_scrollbar_new (Bug#11768).

8756 * xdisp.c (window_hscroll_limited): New function.
8757 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
8758 coordinates when window's hscroll is set to insanely large
8761 2012-07-05 Juanma Barranquero <lekktu@gmail.com>

8830 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
8831 This should be fixed in a better way; see Eli Zaretskii in
8832 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
8833 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
8835 * fileio.c (time_error_value): Rename from special_mtime.
8836 The old name's problems were noted by Eli Zaretskii in
8837 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
8839 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
8840 This variable's comment says Emacs needs at least one GDB-visible
8841 symbol of type enum pvec_type, to work around GDB problems.
8842 The symbol's value doesn't matter.
8844 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
8845 that causes compilation to fail on pre-C99 compilers.
8847 2012-07-04 Juanma Barranquero <lekktu@gmail.com>

8875 abusing vector->header.next.nbytes.
8876 (live_vector_p): Use PVEC_TYPE.
8877 (mark_object): Adapt code to extract pvectype. Use switch.
8879 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>

8886 Fix compilation with --enable-gcc-warnings and -O1
8888 * doprnt.c (doprnt): Change type of tem to int, initialize
8889 to avoid compiler warning. Add eassert.
8890 * search.c (simple_search): Initialize match_byte to avoid
8891 compiler warning. Add eassert.
8893 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8895 Avoid weird behavior with large horizontal scrolls.
8896 Without this change, for example, large hscroll values would
8897 mess up Emacs's display on Fedora 15 x86, presumably due to
8898 overflows in int calculations in the display code.
8899 Also, if buffers had long lines, Emacs would freeze.
8900 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
8901 (set_window_hscroll): New function, containing the old guts of
8902 Fset_window_hscroll. Return the clipped value.
8903 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.

8915 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
8916 since GCC 4.4.6 issues a bogus warning for them.
8918 Fix bugs in file timestamp newness comparisons.
8919 * fileio.c (Ffile_newer_than_file_p):
8920 * lread.c (Fload): Use full timestamp resolution of files,
8921 not just the 1-second resolution, so that files that are only
8922 slightly newer still count as newer.
8923 * fileio.c (Ffile_newer_than_file_p): Don't assume file
8924 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
8926 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
8928 * fileio.c: Improve handling of file time marker. (Bug#11852)

8935 * fileio.c (Finsert_file_contents): Properly handle st_mtime
8936 marker for non-existing file. (Bug#11852)
8938 2012-07-03 Glenn Morris <rgm@gnu.org>
8940 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
8941 and did not make it into globals.h).

9034 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
9036 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
9037 wrapper that is not needed because the wrapped code is a no-op (zero
9038 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
9039 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
9041 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
9043 * alloc.c (mark_buffer): Simplify. Remove prototype.
9044 (mark_object): Add comment. Reorganize marking of vector-like
9045 objects. Use CHECK_LIVE for all vector-like objects except buffers
9046 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
9047 Avoid redundant calls to mark_vectorlike for bool vectors.
9049 2012-06-30 Glenn Morris <rgm@gnu.org>
9051 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
9053 * epaths.in (PATH_SITELOADSEARCH): New.
9054 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
9055 This is rather than relying on --enable-locallisppath elements
9056 having "site-lisp" in their names. (Bug#10208#25, 11658)
9058 2012-06-30 Eli Zaretskii <eliz@gnu.org>
9060 * w32proc.c (sys_select): Accept and ignore one more argument.
9062 * w32.c (emacs_gnutls_pull): Call select with one more argument.
9064 * sysselect.h [DOS_NT]: Don't include sys/select.h.
9065 (pselect) [!MS_DOS]: Redirect to sys_select.
9067 * sysdep.c: Don't include dos.h and dosfns.h.
9069 * process.c (sys_select):
9070 * msdos.c (sys_select): Accept one more argument and ignore it.
9072 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
9073 adapt data types and code to that.
9076 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
9077 which clashes with the gnulib function of the same name.
9079 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
9081 * font.c (font_style_to_value, font_style_symbolic)
9082 (font_prop_validate_style): Add type checks for values in
9085 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
9087 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
9090 2012-06-29 Eli Zaretskii <eliz@gnu.org>
9092 * xdisp.c (try_window_id): Undo last change.
9094 * w32.c (getwd): Adjust commentary about startup_dir.
9095 (init_environment): Always call sys_access, even in non-MSVC
9096 builds. Don't chdir to the directory of the Emacs executable.
9097 This undoes code from 1997 which was justified by the need to
9098 "avoid conflicts when removing and renaming directories". But its
9099 downside was that every relative file name was being interpreted
9100 relative to the directory of the Emacs executable, which can never
9101 be TRT. In particular, it broke sys_access when called with
9102 relative file names.
9103 (sys_access): Map GetLastError to errno.
9105 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9107 * window.h (struct window): Change type of 'fringes_outside_margins'
9108 to bitfield. Fix comment. Adjust users accordingly.
9109 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
9111 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
9114 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
9116 * gnutls.c (emacs_gnutls_handshake):
9117 Add QUIT to make the loop interruptible.
9119 2012-06-29 Glenn Morris <rgm@gnu.org>
9121 * charset.c (init_charset): Make lack of etc/charsets fatal.
9123 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9125 * editfns.c (region_limit): Fix type mismatch.
9127 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9129 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
9130 undefined. Convert from xassert to eassert.
9131 * nsmenu.m: Convert from xassert to eassert.
9132 * nsterm.m: Likewise.
9134 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
9136 * editfns.c (region_limit): Clip to narrowing (bug#11770).
9138 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
9140 Avoid integer overflow on scroll-left and scroll-right.
9141 * window.c (HSCROLL_MAX): New macro.
9142 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
9143 overflow when requested scroll falls outside ptrdiff_t range.
9145 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9147 * window.h (struct window): Change type of 'hscroll',
9148 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
9149 'last_modified' and 'last_overlay_modified' to EMACS_INT.
9150 Adjust users accordingly.
9151 * xdisp.c (try_cursor_movement): Replace type check with eassert.
9152 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
9153 from EMACS_INT to ptrdiff_t.
9154 (make_window): Omit redundant initialization.
9156 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
9158 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
9160 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9162 * window.h (struct window): Change type of 'use_time' and
9163 'sequence_number' from Lisp_Object to int.
9164 * frame.c (make_frame): Adjust users accordingly.
9165 * print.c (print_object): Likewise.
9166 * window.c (select_window, Fwindow_use_time, make_parent_window)

9172 enabled with --enable-checking=[all,glyphs] configure option.
9173 Fix GLYPH_DEBUG usage assuming that it may be undefined,
9174 adjust comments accordingly.

9223 * alloc.c (allocate_string_data): Remove dead code.
9224 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to
9225 avoid GCC warning about unused macro.
9227 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
9229 * alloc.c (allocate_string): Omit intervals initialization.
9230 * alloc.c (make_uninit_multibyte_string): Initialize intervals
9231 as in make_pure_string and make_pure_c_string.

9285 2012-06-26 Dmitry Antipov <dmantipov@yandex.ru>
9287 * alloc.c: Remove build_string.
9288 * lisp.h: Define build_string as static inline. This provides
9289 a better opportunity to optimize away calls to strlen when the
9290 function is called with compile-time constant argument.
9291 * image.c (imagemagick_error): Convert to build_string.
9292 * w32proc.c (sys_spawnve): Likewise.
9293 * xterm.c (x_term_init): Likewise.
9295 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
9297 Use sprintf return value instead of invoking strlen on result.
9298 In the old days this wasn't portable, since some sprintf
9299 implementations returned char *. But they died out years ago and
9300 Emacs already assumes sprintf returns int.
9301 Similarly for float_to_string.
9302 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
9303 * ccl.c (ccl_driver):
9304 * character.c (string_escape_byte8):

9307 * print.c (print_object):
9308 * xdisp.c (message_dolog):
9309 * xfns.c (syms_of_xfns):
9310 Use sprintf or float_to_string result to avoid need to call strlen.
9311 * data.c (Fnumber_to_string):
9312 Use make_unibyte_string, since the string must be ASCII.
9313 * lisp.h, print.c (float_to_string): Now returns int length.
9314 * term.c (produce_glyphless_glyph):
9315 Use sprintf result rather than recomputing it.
9317 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
9318 * Makefile.in (ALL_CFLAGS):
9319 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
9320 * gmalloc.c, regex.c: Include <config.h> unconditionally.

9324 * dispextern.h (xstrcasecmp): Define to library function
9325 strcasecmp if available.
9326 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.

9341 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
9343 * gtkutil.c (get_utf8_string): Remove redundant assignment.
9344 sprintf already null-terminates its output.
9346 * xfns.c (x_window): Remove redundant cast.
9348 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
9350 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
9351 `const char *' to `char *' to avoid compiler warning.
9353 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
9355 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
9356 instead of truncating it to 63 (admittedly a generous limit).
9358 * process.c: Fix spelling and caps in comments.
9360 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
9362 * emacs.c (setpgrp): Remove definition, unused.

9374 * systime.h [WINDOWSNT]: Include sys/time.h.
9376 * s/ms-w32.h (struct timespec): Definition moved from
9377 nt/inc/sys/time.h. Suggested by Paul Eggert <eggert@cs.ucla.edu>.
9379 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>

9407 No need for separate decl merely because of _Noreturn.
9408 * sound.c (sound_warning, parse_sound):
9409 Remove unnecessary forward decls.
9411 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
9413 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
9414 * lisp.h (WAIT_READING_MAX): New macro.
9415 * dispnew.c (Fsleep_for, sit_for):
9416 * keyboard.c (kbd_buffer_get_event):
9417 * process.c (Faccept_process_output):
9418 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
9419 This improves on the previous patch, which introduced a bug
9420 when time_t is unsigned and as wide as intmax_t.
9421 See <http://bugs.gnu.org/9000#51>.
9423 2012-06-23 Eli Zaretskii <eliz@gnu.org>
9425 * dispnew.c (sit_for, Fsleep_for):
9426 * keyboard.c (kbd_buffer_get_event):

9428 comparing a 32-bit time_t with a 64-bit INTMAX_MAX.
9430 2012-06-23 Juanma Barranquero <lekktu@gmail.com>
9432 * makefile.w32-in: Update dependencies.
9434 * w32.c (ltime): Add return type and declare static.
9435 (w32_get_internal_run_time): Remove usused variable `time_100ns'.
9437 2012-06-23 Paul Eggert <eggert@cs.ucla.edu>
9439 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
9440 Privately reported by Herbert J. Skuhra.
9441 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
9443 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
9444 not make_lisp_timeval, when the argument is of type EMACS_TIME.
9446 2012-06-23 Eli Zaretskii <eliz@gnu.org>
9448 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
9449 last argument of make_unibyte_string.
9451 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
9452 language ID in the event parameters.
9454 * w32term.c (w32_read_socket): Put the new keyboard codepage into
9455 event.code, not the obscure "character set ID".
9457 2012-06-23 Chong Yidong <cyd@gnu.org>
9459 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.
9461 2012-06-23 Eli Zaretskii <eliz@gnu.org>
9463 Fix the MS-Windows build broken by 2012-06-22T21:17:42Z!eggert@cs.ucla.edu.
9464 * w32.c (fdutimens): New function.
9466 * w32proc.c (sys_select): Adapt to change in the EMACS_TIME type.
9468 * s/ms-w32.h (pselect): Redirect to sys_select.

9474 use_relocatable_buffers.
9476 2012-06-23 Paul Eggert <eggert@cs.ucla.edu>
9478 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
9479 Privately reported by Herbert J. Skuhra.
9480 [__FreeBSD__]: Remove "*/" typo after "#include".
9481 (timeval_to_EMACS_TIME) [__FreeBSD__]: New static function.
9482 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.

9486 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
9488 Support higher-resolution time stamps (Bug#9000).
9489 The time stamps are only nanosecond-resolution at the C level,
9490 since that's the best that any real-world system supports now.
9491 But they are picosecond-resolution at the Lisp level, as that's
9492 easy, and leaves room for future OS improvements.
9494 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
9497 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
9498 Don't get current time unless it's needed.
9500 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
9501 now provides it if it's absent.
9502 (start_atimer): Port to higher-res time stamps.
9503 Check for time stamp overflow. Don't get current time more
9504 often than is needed.
9506 * buffer.h (struct buffer): Buffer modtime now has high resolution.
9507 Include systime.h, not time.h.
9508 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
9510 * dired.c: Include stat-time.h.
9511 (Ffile-attributes): File times now have higher resolution.
9513 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
9514 (struct image): Timestamp now has higher resolution.
9516 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
9517 has at least microseconds now. All uses removed.
9518 (update_frame, update_single_window, update_window, update_frame_1)
9519 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
9520 (duration_to_sec_usec): Remove; no longer needed.
9522 * editfns.c (time_overflow): Now extern.
9523 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
9524 (float-time, Fformat_time_string, Fcurrent_time_string)
9525 (Fcurrent_time_zone): Accept and generate higher-resolution
9527 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
9528 (decode_time_components, lisp_seconds_argument): New functions.
9529 (make_time): Now static.
9530 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
9531 Report an error if the time is invalid, rather than having the caller
9534 * fileio.c: Include <stat-time.h>
9535 (Fcopy_file): Copy higher-resolution time stamps.
9536 Prefer to set the time stamp via a file descriptor if that works.

9553 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
9554 Port to higher-resolution time stamps. Do not assume time_t is signed.
9555 (decode_timer): New function. Timers are now vectors of length 9,
9556 not 8, to accommodate the picosecond component.
9557 (timer_check_2): Use it.
9559 * nsterm.m (select_timeout, timeval_subtract): Remove.
9560 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
9561 as they're a bit more accurate and handle overflow better.

9563 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
9564 * nsterm.h (ns_select): Adjust prototype.
9566 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
9567 us-resolution time stamps.
9568 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
9570 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
9572 * lisp.h (time_overflow): New decl.
9573 (wait_reading_process_output): First arg is now intmax_t, not int,
9574 to accommodate larger waits.
9576 * process.h (struct Lisp_Process.read_output_delay):
9577 Now counts nanoseconds, not microseconds.
9578 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about

9583 (Faccept_process_output, wait_reading_process_output):
9584 Check for time stamp overflow. Do not assume time_t is signed.
9585 (select_wrapper): Remove; we now use pselect.
9586 (Fprocess_attributes): Now generates ns-resolution time stamps.
9588 * sysdep.c: Include utimens.h. Don't include utime.h
9589 or worry about struct utimbuf; gnulib does that for us now.

9592 (set_file_times): Now sets ns-resolution time stamps.
9593 New arg FD; all uses changed.

9596 Now returns ns-resolution time stamp. All uses changed.
9597 Check for time stamp overflow.
9599 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
9600 provides a substitute now.
9602 * systime.h: Include timespec.h rather than sys/time.h and time.h,
9603 since it guarantees struct timespec.
9604 (EMACS_TIME): Now struct timespec, so that we can support
9605 ns-resolution time stamps.
9606 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
9607 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
9608 (EMACS_USECS): Remove.
9609 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
9610 so multiply the arg by 1000 before storing it.
9611 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
9613 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):

9620 (make_timeval, make_lisp_time, decode_time_components): New decls.
9621 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
9622 that it mishandled time_t overflow. You can't compare by subtracting!
9623 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
9624 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.

9635 (w32_get_internal_run_time):
9636 Port to higher-resolution Emacs time stamps.
9637 (ltime): Now accepts single 64-bit integer, as that's more convenient

9647 * xselect.c (wait_for_property_change, x_get_foreign_selection):
9648 Check for time stamp overflow, and support ns-resolution time stamps.
9650 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
9651 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
9652 (timeval_subtract): Remove; no longer needed.
9653 (XTflash, XTring_bell, x_wait_for_event):
9654 Port to ns-resolution time stamps. Don't assume time_t is signed.

9660 2012-06-22 Eli Zaretskii <eliz@gnu.org>
9662 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
9663 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
9664 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
9665 staticidx goes up to 1597 out of 1600 = 0x640.)
9667 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
9669 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
9670 Otherwise, the umask might be mistakenly 0 while handling input signals.

9681 access to `contents' member of Lisp_Vector objects with AREF and ASET
9684 2012-06-19 Chong Yidong <cyd@gnu.org>
9686 * frame.c (delete_frame): When selecting a frame on a different

9691 (unwind_format_mode_line): Restore them.
9692 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
9694 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
9695 since tty frames can be explicitly named.
9696 (prepare_menu_bars): Likewise.
9698 * term.c (Ftty_top_frame): New function.
9700 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

9703 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
9704 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
9705 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
9706 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

9715 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
9716 gets killed during executing of this function (Bug#11665).
9717 Try to always return Qt when the buffer has been actually killed.
9718 (Vkill_buffer_query_functions): In doc-string say that functions
9719 run by this hook should not change the current buffer.
9721 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
9723 Fix recently-introduced process.c problems found by static checking.
9724 * process.c (write_queue_push, write_queue_pop, send_process):

9743 * lisp.h (eassert): Assume C89 or later.
9744 This removes the need for CHECK.
9745 (CHECK): Remove. Its comments about always evaluating its
9746 argument were confusing, as 'eassert' typically does not evaluate
9749 * coding.c (produce_chars): Use ptrdiff_t, not int.
9751 * xterm.c (x_draw_underwave): Check for integer overflow.
9752 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

10056 Block-based vector allocation of small vectors.
10057 * lisp.h (struct vectorlike_header): New field `nbytes',
10058 adjust comment accordingly.
10059 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
10060 to denote vector blocks. Adjust users (live_vector_p,

10083 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
10085 * doprnt.c (doprnt): Truncate multibyte char correctly.
10086 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
10087 would mishandle a string argument "Xc" if X was a multibyte
10088 character of length 2: it would truncate after X's first byte
10089 rather than including all of X.
10091 2012-06-06 Chong Yidong <cyd@gnu.org>
10093 * buffer.c (word_wrap): Doc fix.
10095 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

10121 position is past the end of the mode line string.
10123 * buffer.c (buffer_local_value_1): New function, split from
10124 Fbuffer_local_value; can return Qunbound.
10125 (Fbuffer_local_value): Use it.
10126 (Vmode_line_format): Docstring tweaks.
10128 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>

10140 * minibuf.c (Fassoc_string): Remove duplicate declaration.
10142 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
10143 Convert pctcpu and pctmem to Lisp float properly.
10144 Let the compiler fold better, as 100.0/0x8000 is exact.
10146 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
10148 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
10151 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>

10155 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
10157 For a 'struct window', replace some Lisp_Object fields to
10158 bitfields where appropriate, remove unused fields.
10159 * window.h (struct window): Remove unused 'last_mark_x' and
10160 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
10161 change its type from Lisp_Object to bitfield.
10162 Change type of 'force_start', 'optional_new_start',
10163 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
10164 fields from Lisp_Object to bitfield. Adjust users accordingly.
10166 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10168 Pacify gcc -Wdouble-precision when using Xaw.
10169 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
10170 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
10171 Use 'float' consistently, rather than 'float' in most places
10172 and 'double' in a couple of places.
10174 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10176 * xdisp.c (handle_stop): Detect whether we have overlay strings
10177 loaded by testing it->current.overlay_string_index to be
10178 non-negative, instead of checking whether n_overlay_strings is
10179 positive. (Bug#11587)
10181 2012-05-31 Chong Yidong <cyd@gnu.org>
10183 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

10187 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10189 * search.c (search_buffer): Remove calls to
10190 r_alloc_inhibit_buffer_relocation, as it is now called by
10191 maybe_unify_char, which was the cause of relocation of buffer text
10194 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10196 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
10197 for the duration of call to load_charset, to avoid problems with
10198 callers of maybe_unify_char that access buffer text through C
10201 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
10202 decrement the inhibition flag, instead of just setting or
10205 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10207 Remove obsolete '#define static' cruft.
10208 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
10209 This #undef was "temporary" in 2000; it is no longer needed
10210 now that '#define static' has gone away.
10211 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
10212 (gray_bitmap_bits): Remove; no longer needed.
10213 All uses replaced with definiens.
10214 * xterm.c: Include "bitmaps/gray.xbm".
10216 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>

10219 The following changes affect the code only when profiling.
10220 * dispnew.c (__executable_start): Rename from safe_bcopy.
10221 Define only on platforms that need it.
10222 * emacs.c: Include <sys/gmon.h> when profiling.
10223 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
10224 (__executable_start): Remove decl, since lisp.h does it now.
10225 (safe_bcopy): Remove decl; no longer has that name.
10226 (main): Coalesce #if into single bit of code, for simplicity.
10227 Cast pointers to uintptr_t, since standard libraries want integers
10229 * lisp.h (__executable_start): New decl.
10231 2012-05-31 Glenn Morris <rgm@gnu.org>
10233 * image.c (Fimagemagick_types): Doc fix.

10254 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
10256 Do not create empty overlays with the evaporate property (Bug#9642).
10257 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
10258 Bug#9642, but explicitly check that the buffer the overlay would
10259 be moved to is live and rearrange lines to make sure that errors
10260 will not put the overlay in an inconsistent state.
10261 (Fdelete_overlay): Cosmetics.
10263 2012-05-28 Eli Zaretskii <eliz@gnu.org>
10265 * w32term.c (my_bring_window_to_top): New function.
10266 (x_raise_frame): Use handle returned by DeferWindowPos, which
10267 could be different from the original one.

10277 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
10279 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
10280 This avoids undefined behavior that might cause the eassert
10281 to not catch an out-of-range value.
10283 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
10285 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
10286 Update dependencies.
10288 2012-05-27 Eli Zaretskii <eliz@gnu.org>
10290 * bidi.c (bidi_mirror_char): Fix last change.
10292 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>

10297 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
10299 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
10300 Only r_alloc_inhibit_buffer_relocation needed to be added;
10301 the others were already declared.
10303 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
10304 before checking whether it's out of range. Put the check inside
10306 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
10308 2012-05-27 Ken Brown <kbrown@cornell.edu>
10310 * callproc.c (Fcall_process): Restore a line that was accidentally
10311 commented out in the 2011-02-13 change (bug#11547).
10313 2012-05-27 Eli Zaretskii <eliz@gnu.org>
10315 * lisp.h [REL_ALLOC]: Add prototypes for external functions
10316 defined on ralloc.c.
10318 * buffer.c [REL_ALLOC]: Remove prototypes of
10319 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
10320 they are now on lisp.h.
10322 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
10324 * search.c (search_buffer): Use it to inhibit relocation of buffer
10325 text while re_search_2 is doing its job, because re_search_2 is
10326 passed C pointers to buffer text. (Bug#11519)
10328 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
10329 Update value to 24.
10331 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
10332 state after an additional call to move_it_in_display_line_to, keep
10333 the values of it->max_ascent and it->max_descent found for the
10335 (pos_visible_p): Revert the comparison against bottom_y to what it
10336 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
10339 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10341 Fix coding-related core dumps with gcc -ftrapv.
10342 The code was computing A - B, where A and B are pointers, and B is
10343 random garbage. This can lead to core dumps on platforms that
10344 have special pointer registers, and it also leads to core dumps on
10345 x86-64 when compiled with gcc -ftrapv. The fix is to compute
10346 A - B only when B is initialized properly.
10347 * coding.c (coding_set_source, coding_set_destination): Return void.
10348 (coding_change_source, coding_change_destinations): New functions,
10349 with the old behaviors of coding_set_source and coding_set_destination.
10350 All callers that need an offset changed to use these new functions.
10352 2012-05-26 Glenn Morris <rgm@gnu.org>
10354 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)

10360 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
10362 * w32console.c: Include window.h.
10363 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
10365 (initialize_w32_display): Initialize mouse-highlight data.
10367 * w32inevt.c: Include termchar.h and window.h.
10368 (do_mouse_event): Support mouse-autoselect-window. When the mouse
10369 moves, call note_mouse_highlight. If help_echo changed, call
10370 gen_help_event to produce help-echo message in the echo area.
10371 Call clear_mouse_face if mouse_face_hidden is set in the mouse
10374 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10376 * lread.c (read1): Simplify slightly to avoid an overflow warning
10377 with GCC 4.7.0 on x86-64.
10379 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10381 * bidi.c (bidi_mirror_char): Revert last change: an int is
10382 definitely wide enough here.
10384 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
10386 Fix integer width and related bugs (Bug#9874).

10394 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
10396 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

10398 Use int, not EMACS_INT, where int is wide enough.
10399 (inhibit_garbage_collection, Fgarbage_collect):
10400 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10401 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
10402 int might not be wide enough.
10403 (bidi_cache_search, bidi_cache_find, bidi_init_it)
10404 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
10405 (bidi_at_paragraph_end, bidi_find_paragraph_start)
10406 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
10407 (bidi_level_of_next_char, bidi_move_to_visually_next):
10408 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10409 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
10410 (Fkill_buffer, Fset_buffer_major_mode)
10411 (advance_to_char_boundary, Fbuffer_swap_text)

10413 (overlay_touches_p, struct sortvec, record_overlay_string)
10414 (overlay_strings, recenter_overlay_lists)
10415 (adjust_overlays_for_insert, adjust_overlays_for_delete)

10420 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10421 (validate_region): Omit unnecessary test for b <= e,
10422 since that's guaranteed by the previous test.
10423 (adjust_overlays_for_delete): Avoid pos + length overflow.
10424 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
10425 (report_overlay_modification):
10426 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10427 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
10428 Omit pointer cast, which isn't needed anyway, and doesn't work
10429 after the EMACS_INT -> ptrdiff_t change.
10430 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
10431 * buffer.h: Adjust decls to match defn changes elsewhere.
10432 (struct buffer_text, struct buffer):
10433 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10434 Use EMACS_INT, not int, where int might not be wide enough.
10435 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
10436 not int, to avoid needless 32-bit limit on 64-bit hosts.
10437 (exec_byte_code): Use tighter memory-full test, one that checks
10438 for alloca overflow. Don't compute the address of the object just
10439 before an array, as that's not portable. Use EMACS_INT, not
10440 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
10441 * callint.c (Fcall_interactively):
10442 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

10453 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
10454 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10455 (casify_object): Avoid integer overflow when overallocating buffer.
10456 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
10457 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
10458 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
10459 * category.h (CATEGORYP): Don't assume arg is nonnegative.
10460 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the

10463 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10464 For CCL_MapSingle, check that content and value are in int range.
10465 (ccl_driver, Fregister_code_conversion_map):
10466 Check that Vcode_version_map_vector is a vector.
10467 (resolve_symbol_ccl_program): Check that vector header is in range.
10468 Always copy the vector, so that we can check its contents reliably
10469 now rather than having to recheck each instruction as it's being
10470 executed. Check that vector words fit in 'int'.
10471 (ccl_get_compiled_code, Fregister_ccl_program)
10472 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
10473 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

10475 contents are in range.
10476 (Fccl_execute_on_string): Check that status is in range.

10486 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

10499 Don't rely on undefined behavior with signed left shift overflow.
10500 Don't assume unsigned int fits into fixnum, or that fixnum fits
10501 into unsigned int. Don't require max_code to be a valid fixnum;
10502 that's not true for gb10830 4-byte on a 32-bit host. Allow
10503 invalid_code to be a cons, for the same reason. Require code_offset
10504 to be a character. Avoid int overflow if max_char is close
10506 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
10507 this is intended anyway and avoids some undefined behavior.
10508 (load_charset_map): Pass unsigned, not int, as 2nd arg of
10509 INDEX_TO_CODE_POINT, as that's what it expects.
10510 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
10511 * charset.h (DECODE_CHAR): Return int, not unsigned;
10512 this is what was intended anyway, and it avoids undefined behavior.

10514 integer-overflow issues.
10515 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
10516 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
10517 where the argument is EMACS_INT, and this behavior is not intended.
10518 * chartab.c (Fmake_char_table, Fset_char_table_range)
10519 (uniprop_get_decoder, uniprop_get_encoder):
10520 Don't assume fixnum fits in int.
10521 * cmds.c (move_point): New function, that does the gist of
10522 Fforward_char and Fbackward_char, but does so while checking
10523 for integer overflow more accurately.
10524 (Fforward_char, Fbackward_char): Use it.
10525 (Fforward_line, Fend_of_line, internal_self_insert)

11129 (last_escape_glyph_face_id, last_glyphless_glyph_face_id):
11130 (handle_tool_bar_click):
11131 Use int, not unsigned, since we prefer signed and the signedness
11132 doesn't matter here.
11133 (get_next_display_element, next_element_from_display_vector):
11134 Use int, not EMACS_INT, when int is wide enough.

11174 * xterm.c (x_x_to_emacs_modifiers):
11175 Don't assume EMACS_INT overflows nicely into int.
11176 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
11177 may come from Lisp.
11178 (handle_one_xevent): NATNUMP can eval its arg twice.
11179 (x_connection_closed):

11186 2012-05-25 Glenn Morris <rgm@gnu.org>
11188 * lisp.mk (lisp): Update for more files being compiled now.
11190 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
11192 * lread.c: Remove `read_pure' which makes no difference.
11193 (read_pure): Remove var.
11194 (unreadpure): Remove function.
11195 (readevalloop): Don't call read_list with -1 flag.
11196 (read1, read_vector): Don't test read_pure any more.
11197 (read_list): Simplify.
11199 * fileio.c, character.h: Minor style tweaks.

11205 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
11207 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
11208 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
11210 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
11213 This directory predates autoconf and is no longer needed nowadays.
11214 Move its few remaining bits of functionality to where they're needed.
11215 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
11216 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
11217 * m/template.h: Remove.
11218 * Makefile.in (M_FILE): Remove. All uses removed.
11219 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
11220 * lisp.h (USE_LSB_TAG):
11221 * mem-limits.h (EXCEEDS_LISP_PTR):
11222 Use VAL_MAX, not VALBITS, in #if.
11223 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
11224 (EMACS_UINT): Define unconditionally now.
11225 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
11226 (BITS_PER_EMACS_INT): New constants, replacing
11227 what used to be in config.h, but not useful in #if.
11228 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
11229 define them any more.
11230 (VAL_MAX): New macro.
11232 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
11233 BITS_PER_EMACS_INT, in #if.
11234 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
11235 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
11236 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
11237 * s/ms-w32.h (DATA_START):
11238 Move here from removed file m/intel386.h.
11239 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
11240 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
11242 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
11244 Assume C89 or later.
11245 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
11246 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)

11254 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
11255 * xterm.c (input_signal_count): Assume volatile works.
11257 2012-05-21 Ken Brown <kbrown@cornell.edu>
11259 * xgselect.c (xg_select): Fix first argument in call to 'select'

11264 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
11265 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
11267 2012-05-19 Ken Brown <kbrown@cornell.edu>
11269 * xfns.c (x_in_use): Remove `static' qualifier.
11270 * xterm.h (x_in_use): Declare.
11271 * xgselect.c: Include xterm.h.
11272 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
11273 and `display_arg' (bug#9754).
11275 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
11277 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
11279 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
11280 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
11282 2012-05-18 Eli Zaretskii <eliz@gnu.org>
11284 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
11286 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
11287 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
11289 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
11290 reference to image_cache->refcount.
11291 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
11293 2012-05-17 Juri Linkov <juri@jurta.org>
11295 * search.c (Fword_search_regexp, Fword_search_backward)
11296 (Fword_search_forward, Fword_search_backward_lax)
11297 (Fword_search_forward_lax): Move functions to isearch.el
11298 (bug#10145, bug#11381).
11300 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
11302 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
11304 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
11306 * lread.c (init_obarray): Declare Qt and Qnil as special.
11308 2012-05-14 Glenn Morris <rgm@gnu.org>
11310 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
11311 Put "libexec" before "bin", for the sake of init_callproc_1.
11313 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11315 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
11317 * unexaix.c: Port to more-recent AIX compilers.
11318 (report_error, report_error_1, make_hdr, copy_sym)
11319 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
11320 Make arguments const char *, not char *, to avoid violations of C
11321 standard and to fix some AIX warnings reported by Gilles Pion.
11323 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11325 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
11326 already have overlays loaded.
11327 (handle_single_display_spec): Before returning without displaying
11328 fringe bitmap, synchronize the bidi iterator with the main display
11329 iterator, by calling iterate_out_of_display_property.
11330 (iterate_out_of_display_property): Detect buffer iteration by
11331 testing that it->string is a Lisp string.
11332 (get_next_display_element): When the current object is exhausted,
11333 and there's something on it->stack, call set_iterator_to_next to
11334 proceed with what's on the stack, instead of returning zero.
11335 (set_iterator_to_next): If called at the end of a Lisp string,
11336 proceed to consider_string_end without incrementing string
11337 position. Don't increment display vector index past the end of
11338 the display vector. (Bug#11417)
11339 (pos_visible_p): Don't report a position visible when move_it_to
11340 stopped at the last line of window, which happens to be scanned
11341 backwards by the bidi iteration. (Bug#11464)
11343 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11345 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
11346 and right-margin display specs even if the spec is invalid or we
11347 are on a TTY, and thus unable to display on the fringes.
11348 That's because the text with the property will not be displayed anyway,
11349 so we need to signal to the caller that this is a "replacing"
11350 display spec. This fixes display when the spec is invalid or we
11353 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11355 * unexaix.c (make_hdr): Fix typo in prototype.
11356 This bug broke the build on AIX. Problem reported by Gilles Pion.
11358 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
11360 * keyboard.c (kbd_buffer_get_event): Read special events also in
11361 batch mode. (Bug#11415)
11363 2012-05-12 Glenn Morris <rgm@gnu.org>
11365 * ns.mk: Update for ns_appbindir no longer having trailing "/".
11367 2012-05-12 Eli Zaretskii <eliz@gnu.org>
11369 * lisp.mk (lisp): Add newcomment.elc.
11371 2012-05-12 Glenn Morris <rgm@gnu.org>
11373 * Makefile.in (MKDIR_P): New, set by configure.
11374 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
11376 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
11378 Remove unused function hourglass_started.
11379 * dispextern.h (hourglass_started):
11380 * w32fns.c (hourglass_started):
11381 * xdisp.c (hourglass_started): Remove.
11383 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
11385 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
11386 Update dependencies.
11388 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
11390 * xgselect.c (xg_select): Put maxfds+1 into a var.
11391 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
11393 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
11395 2012-05-10 Dave Abrahams <dave@boostpro.com>
11397 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
11398 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
11400 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
11402 * dbusbind.c (xd_registered_buses): New internal Lisp object.
11403 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
11404 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
11405 Initialize xd_registered_buses.
11407 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
11409 Untag more efficiently if USE_LSB_TAG.
11410 This is based on a proposal by YAMAMOTO Mitsuharu in
11411 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
11412 For an admittedly artificial (nth 8000 longlist) benchmark on
11413 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
11414 Emacs's overall text size by 1%.
11415 * lisp.h (XUNTAG): New macro.
11416 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
11417 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
11418 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
11419 * eval.c (Fautoload):
11420 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
11421 * frame.h (XFRAME): Use XUNTAG.
11423 Port recent dbusbind.c changes to 32-bit --with-wide-int.
11424 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
11425 Remove unportable assumptions about print widths of types like
11427 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
11428 intptr_t when converting between pointer and integer, to avoid GCC
11429 warnings about wrong width.
11431 2012-05-09 Eli Zaretskii <eliz@gnu.org>
11433 * w32proc.c (new_child): Force Windows to reserve only 64KB of
11434 stack for each reader_thread, instead of defaulting to 8MB
11435 determined by the linker. This avoids failures in creating
11436 subprocesses on Windows 7, see the discussion in this thread:
11437 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
11439 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
11441 Fix up display of the *Minibuf-0* buffer in the mini window.
11442 * keyboard.c (read_char): Don't clear the echo area if there's no
11444 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
11445 contents of *Minibuf-0*) if there's no message displayed in its stead.
11447 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
11449 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
11452 2012-05-06 Chong Yidong <cyd@gnu.org>
11454 * lisp.mk (lisp): Update.
11456 2012-05-05 Jim Meyering <meyering@redhat.com>
11458 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
11460 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
11462 * data.c (PUT_ERROR): New macro.
11463 (syms_of_data): Use it. Add new error type `user-error'.
11464 * undo.c (user_error): New function.
11465 (Fprimitive_undo): Use it.
11466 * print.c (print_error_message): Adjust print style for `user-error'.
11467 * keyboard.c (user_error): New function.
11468 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
11470 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
11472 Do not limit current-time-string to years 1000..9999.
11473 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
11474 (Fcurrent_time_string): Support any year that is supported by the
11475 underlying localtime representation. Don't use asctime, as it
11476 has undefined behavior for years outside the range -999..9999.
11478 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
11480 Fix race conditions involving setenv, gmtime, localtime, asctime.
11481 Without this fix, interrupts could mess up code that uses these
11482 nonreentrant functions, since setting TZ invalidates existing
11483 tm_zone or tzname values, and since most of these functions return
11484 pointers to static storage.
11485 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
11486 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
11487 Grow the critical sections to include not just invoking
11488 localtime/gmtime, but also accessing these functions' results
11489 including their tm_zone values if any, and any related TZ setting.
11490 (format_time_string): Last arg is now struct tm *, not struct tm **,
11491 so that the struct tm is saved in the critical section.
11492 All callers changed. Simplify allocation of initial buffer, partly
11493 motivated by the fact that memory allocation needs to be outside
11494 the critical section.
11496 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
11498 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
11499 with RESET_INTERVAL.
11501 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
11502 Remove duplicated buffer name initialization.
11504 2012-05-02 Jim Meyering <jim@meyering.net>
11506 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
11508 * xfns.c (x_window): Use xstrdup (Bug#11375).
11510 2012-05-02 Eli Zaretskii <eliz@gnu.org>
11512 * xdisp.c (pos_visible_p): If already at a newline from the
11513 display string before the 'while' loop, don't walk back the glyphs
11514 from it3.glyph_row. Solves assertion violation when the display
11515 string begins with a newline (egg.el). (Bug#11367)
11517 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
11519 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
11522 2012-05-01 Glenn Morris <rgm@gnu.org>
11524 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
11525 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
11526 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
11527 All were removed before 23.1.
11529 * dispnew.c: Remove HAVE_LIBNCURSES test;
11530 it is always true on relevant platforms.
11532 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
11533 Rename from LD_SWITCH_X_SITE_AUX_RPATH.

11545 Do not avoid creating empty evaporating overlays (Bug#9642).
11546 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
11547 That is, do not delete an evaporating overlay if it becomes
11548 empty after its bounds are adjusted to fit within its buffer.
11549 This fix caused other problems, and I'm reverting it until we get
11550 to the bottom of them.
11552 2012-04-27 Chong Yidong <cyd@gnu.org>
11554 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
11556 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11558 * xdisp.c (pos_visible_p): If the window start position is beyond
11559 ZV, start the display from buffer beginning. Prevents assertion
11560 violation in init_iterator when the minibuffer window is scrolled
11561 via the scroll bar.
11563 * window.c (window_scroll_pixel_based): Likewise.
11565 2012-04-27 Chong Yidong <cyd@gnu.org>

11579 2012-04-26 Eli Zaretskii <eliz@gnu.org>
11581 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
11582 display element, check also the underlying string or buffer
11583 character. (Bug#11341)
11585 * w32menu.c: Include w32heap.h.
11586 (add_menu_item): If the call to AppendMenuW (via
11587 unicode_append_menu) fails, disable Unicode menus only if we are
11588 running on Windows 9X/Me.
11590 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
11592 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
11593 (xgetint): Add missing shift for LSB tags.
11595 2012-04-24 Martin Rudalics <rudalics@gmx.at>
11597 * keyboard.c (read_char): Don't wipe echo area for select window

11603 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
11604 manipulation of :loaded-from data.
11606 2012-04-23 Juanma Barranquero <lekktu@gmail.com>

11609 now a cons (bug#11311).
11611 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
11613 Do not create empty overlays with the evaporate property (Bug#9642).
11614 * buffer.c (Fmove_overlay): Delete an evaporating overlay
11615 if it becomes empty after its bounds are adjusted to fit within
11616 its buffer. Without this fix, in a nonempty buffer (let ((o
11617 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
11618 yields an empty overlay that has the evaporate property, which is
11619 not supposed to happen.

11954 2012-04-09 Eli Zaretskii <eliz@gnu.org>
11956 * xdisp.c (set_cursor_from_row): If the display string appears in
11957 the buffer at position that is closer to point than the position
11958 after the display string, display the cursor on the first glyph of
11959 the display string. Fixes cursor display when a 'display' text
11960 property immediately follows invisible text. (Bug#11094)
11962 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
11964 composite.c: use 'double' consistently
11965 * composite.c (get_composition_id): Use 'double' consistently
11966 instead of converting 'float' to 'double' and vice versa; this is
11967 easier to understand and avoids a GCC warning.
11969 2012-04-09 Glenn Morris <rgm@gnu.org>
11971 * Makefile.in: Generate leim-list with bootstrap-emacs, in
11972 preparation for dumping it with emacs. (Bug#4789)
11973 (leimdir): New variable.
11974 ($(leimdir)/leim-list.el): New rule.
11975 (emacs$(EXEEXT)): Depend on leim-list.el.

11993 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
11994 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
11995 (mark_memory): Mark Lisp_Objects only if pointers might hide in
11996 objects, as mark_maybe_pointer will catch them otherwise.
11997 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
11998 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
12000 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
12002 Fix typo that broke non-Windows builds.

12005 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12007 Support building on MS-Windows with libxml2.
12009 * makefile.w32-in (OBJ2): Add xml.$(O).

12016 [!WINDOWSNT]: New macros.
12017 (init_libxml2_functions, libxml2_loaded_p): New functions.
12018 (parse_region): Call fn_xmlCheckVersion instead of using the macro
12019 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
12020 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
12021 Calls xmlCleanupParser only if libxml2 was loaded (or statically
12023 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
12024 Call init_libxml2_functions before calling libxml2 functions.
12025 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
12027 * emacs.c: Don't include libxml/parser.h.
12028 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
12029 xmlCleanupParser directly.
12031 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
12033 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12035 * indent.c (Fvertical_motion): If there is a display string at
12036 point, use it.vpos to compute how many lines to backtrack after
12037 move_it_to point. (Bug#11133)
12039 2012-04-06 Eli Zaretskii <eliz@gnu.org>
12041 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
12042 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
12043 about subtle differences between FETCH_CHAR* and STRING_CHAR*
12044 macros related to unification of CJK characters. For the details,
12045 see the discussion following the message here:
12046 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
12048 2012-04-04 Chong Yidong <cyd@gnu.org>
12050 * keyboard.c (Vdelayed_warnings_list): Doc fix.
12052 2012-04-01 Eli Zaretskii <eliz@gnu.org>
12054 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
12055 instead of alloca. (Bug#11138)
12057 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>

12062 2012-03-31 Eli Zaretskii <eliz@gnu.org>
12064 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
12065 position we get to after a call to move_it_to fails the
12066 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
12067 only if we wind up in a string from display property. (Bug#11063)
12069 * window.c (Fdelete_other_windows_internal): Invalidate the row
12070 and column information about mouse highlight, so that redisplay
12071 restores it after reallocating the glyph matrices. (Bug#7464)
12073 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
12074 string comes from a `display' text property, use the buffer
12075 position of that property as if we actually saw that position in
12077 (move_it_by_lines): Remove the assertion that
12078 "it->current_x == 0 && it->hpos == 0" which can be legitimately
12079 violated when there's a before-string at the beginning of a line.
12082 2012-03-30 Eli Zaretskii <eliz@gnu.org>
12084 * xdisp.c (append_space_for_newline): If the default face was
12085 remapped, use the remapped face for the appended newline.
12086 (extend_face_to_end_of_line): Use the remapped default face for
12087 extending the face to the end of the line.
12088 (display_line): Call extend_face_to_end_of_line when the default
12089 face was remapped. (Bug#11068)
12091 2012-03-29 Eli Zaretskii <eliz@gnu.org>
12093 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
12095 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
12097 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
12099 2012-03-27 Glenn Morris <rgm@gnu.org>
12101 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
12104 2012-03-26 Kenichi Handa <handa@m17n.org>
12106 * dispextern.h (struct glyph): Fix previous change. Change the
12107 bit length of glyphless.ch to 25 (Bug#11082).
12109 2012-03-26 Chong Yidong <cyd@gnu.org>
12111 * keyboard.c (Vselection_inhibit_update_commands): New variable.
12112 (command_loop_1): Use it; inhibit selection update for
12113 handle-select-window too (Bug#8996).
12115 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
12117 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
12119 2012-03-25 Kenichi Handa <handa@m17n.org>
12121 * dispextern.h (struct glyph): Change the bit length of
12122 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
12124 2012-03-24 Eli Zaretskii <eliz@gnu.org>
12126 * s/ms-w32.h (tzname): Include time.h before redirecting to
12127 _tzname. Fixes the MSVC build. (Bug#9960)
12129 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
12131 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
12134 * xterm.c (XTread_socket): Only modify handling_signal if
12135 !SYNC_INPUT. (Bug#11080)
12137 2012-03-23 Eli Zaretskii <eliz@gnu.org>
12139 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
12140 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
12141 when fetching a multibyte character consumes more bytes than
12142 CHAR_BYTES returns, due to unification of CJK characters in
12143 string_char. (Bug#11073)
12145 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
12147 * process.c (wait_reading_process_output): Handle pty disconnect
12148 by refraining from sending oneself a SIGCHLD (bug#10933).

12155 Mark string as coming from a prefix property.
12156 (handle_face_prop): Use default face for prefix strings (Bug#4281).
12157 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
12159 2012-03-21 Chong Yidong <cyd@gnu.org>
12161 * xfaces.c (Vface_remapping_alist): Doc fix.
12163 2012-03-20 Eli Zaretskii <eliz@gnu.org>
12165 * w32proc.c (Fw32_set_console_codepage)
12166 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
12169 2012-03-20 Chong Yidong <cyd@gnu.org>
12171 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
12172 to reflect default non-nil value of redisplay-dont-pause.
12174 2012-03-19 Kenichi Handa <handa@m17n.org>
12176 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
12177 it fit in a valid range (Bug#11003).
12179 2012-03-18 Eli Zaretskii <eliz@gnu.org>
12181 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
12182 that is not from display property, accept the row as a "cursor
12183 row" if one of the string's character has a non-nil `cursor'
12184 property. Fixes cursor positioning when there are newlines in
12185 overlay strings, e.g. in icomplete.el. (Bug#11035)
12187 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
12189 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
12191 2012-03-12 Chong Yidong <cyd@gnu.org>
12193 * eval.c (inhibit_lisp_code): Rename from
12194 inhibit_window_configuration_change_hook; move from window.c.
12196 * xfns.c (unwind_create_frame_1, Fx_create_frame):
12197 * window.c (run_window_configuration_change_hook)
12198 (syms_of_window): Callers changed.

12218 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
12221 2012-03-03 Glenn Morris <rgm@gnu.org>
12223 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
12225 2012-03-02 Eli Zaretskii <eliz@gnu.org>
12227 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
12228 position past the first glyph_row that ends at ZV. (Bug#10902)
12229 (redisplay_window, next_element_from_string): Fix typos in
12231 (redisplay_window): Pass to move_it_vertically the margin in
12232 pixels, not in screen lines.
12234 2012-03-02 Glenn Morris <rgm@gnu.org>
12236 * buffer.c (buffer-list-update-hook): Doc fix.
12238 2012-02-29 Eli Zaretskii <eliz@gnu.org>
12240 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
12241 push_it before setting up the iterator for the first overlay
12242 string, even if we have an empty string loaded.
12243 (next_overlay_string): If there's an empty string on the iterator
12244 stack, pop the stack. (Bug#10903)
12246 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
12248 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
12249 Suggested by Stefan Monnier in
12250 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
12251 * alloc.c (widen_to_Lisp_Object): New static function.
12252 (mark_memory): Also mark Lisp_Objects by fetching pointer words
12253 and widening them to Lisp_Objects. This would work even if
12254 USE_LSB_TAG is defined and wide integers are used, which might
12255 happen in a future version of Emacs.
12257 2012-02-25 Chong Yidong <cyd@gnu.org>
12259 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
12262 * xselect.c (Fx_selection_exists_p): Doc fix.

12264 before saving to clipboard manager.
12266 2012-02-24 Chong Yidong <cyd@gnu.org>
12268 * keyboard.c (process_special_events): Handle all X selection
12269 requests in kbd_buffer, not just the next one (Bug#8869).
12271 2012-02-23 Chong Yidong <cyd@gnu.org>
12273 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
12274 call when setting menu-bar-lines and tool-bar-lines parameters.
12275 (unwind_create_frame_1): New helper function.
12277 * window.c (inhibit_window_configuration_change_hook): New var.
12278 (run_window_configuration_change_hook): Obey it.
12279 (syms_of_window): Initialize it.
12281 2012-02-22 Chong Yidong <cyd@gnu.org>

12296 when computing $valmask.
12298 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
12299 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
12300 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
12301 It's useless in that case, and it can cause problems on hosts
12302 that allocate halves of EMACS_INT values separately.
12303 Reported by Dan Horák. Diagnosed by Andreas Schwab in
12304 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
12305 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
12306 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
12307 it avoids undefined behavior on hosts where shifting right by more
12308 than the word width has undefined behavior.
12310 2012-02-19 Chong Yidong <cyd@gnu.org>
12312 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
12313 (Funhandled_file_name_directory, Ffile_name_as_directory)

12330 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
12332 2012-02-15 Chong Yidong <cyd@gnu.org>
12334 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
12335 marked as special. Also, starting docstrings with * is obsolete.

12350 2012-02-12 Chong Yidong <cyd@gnu.org>
12352 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
12353 as that creates a dangerous corner case.
12355 * window.c (Fdelete_window_internal): Invalidate the mouse
12356 highlight (Bug#9904).
12358 2012-02-12 Glenn Morris <rgm@gnu.org>

12361 (Fx_get_selection_internal, Fx_disown_selection_internal)
12362 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
12363 * nsselect.m (Fx_own_selection_internal)
12364 (Fx_disown_selection_internal, Fx_selection_exists_p)
12365 (Fx_selection_owner_p, Fx_get_selection_internal):
12366 Sync docs and argument specs with the xselect.c versions.
12368 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
12370 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.

12374 * w32select.c (Fx_selection_exists_p): Sync doc string and
12375 argument list with xselect.c. (Bug#10783)
12377 * w16select.c (Fx_selection_exists_p): Sync doc string and

12388 2012-02-07 Chong Yidong <cyd@gnu.org>
12390 * buffer.c (Fbuffer_local_variables)
12391 (buffer_lisp_local_variables): Handle unbound vars correctly;
12392 don't let Qunbound leak into Lisp.
12394 2012-02-07 Glenn Morris <rgm@gnu.org>
12396 * image.c (Fimagemagick_types): Doc fix.
12398 * image.c (imagemagick-render-type): Change it from a lisp object
12399 to an integer. Move the doc here from the lisp manual.
12400 Treat all values not equal to 0 the same.
12402 2012-02-06 Chong Yidong <cyd@gnu.org>
12404 * doc.c (store_function_docstring): Avoid applying docstring of

12423 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
12424 after rounding frame sizes. (Bug#9723)
12426 2012-02-04 Eli Zaretskii <eliz@gnu.org>
12428 * keyboard.c (adjust_point_for_property): Don't position point
12429 before BEGV. (Bug#10696)
12431 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
12433 Handle overflow when computing char display width (Bug#9496).
12434 * character.c (char_width): Return EMACS_INT, not int.
12435 (char_width, c_string_width): Check for overflow when
12436 computing the width; this is possible now that individual
12437 characters can have unbounded width. Problem introduced
12438 by merge from Emacs 23 on 2012-01-19.

12923 2011-11-30 Eli Zaretskii <eliz@gnu.org>
12925 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
12926 verifies glyph row's hash code--we have just reallocated the
12927 glyphs, so their contents can be complete garbage. (Bug#10164)
12929 2011-11-30 Juanma Barranquero <lekktu@gmail.com>
12931 * dispnew.c (adjust_glyph_matrix) [XASSERTS]: Add missing check.
12933 2011-11-30 Eli Zaretskii <eliz@gnu.org>
12935 * dispnew.c (adjust_glyph_matrix) [XASSERTS]: Ensure ROW's
12936 attributes are tested _before_ calling verify_row_hash, to protect
12937 against GCC re-ordering of the tests. (Bug#10164)
12939 2011-11-29 Jan Djärv <jan.h.d@swipnet.se>

12944 if net_wm_state_hidden_seen is non-zero (Bug#10002)
12945 (get_current_wm_state): Set net_wm_state_hidden_seen to 1 if
12946 _NET_WM_STATE_HIDDEN is in NET_WM_STATE.
12948 2011-11-28 Paul Eggert <eggert@cs.ucla.edu>
12950 Remove GCPRO-related macros that exist only to avoid shadowing locals.

12960 * dispnew.c (scrolling_window): Truncate overlaps in copy destination
12961 of scroll runs so as to avoid assigning disabled bogus rows and
12962 unnecessary graphics copy operations.
12964 2011-11-27 Eli Zaretskii <eliz@gnu.org>
12966 * s/ms-w32.h (utimbuf) [_MSC_VER]: Don't define.

12972 * lisp.h (GCTYPEBITS): Move before first use.
12973 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
12974 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in
12975 this macro definition.
12977 * s/ms-w32.h (tzname): Redirect to _tzname for all values of
12980 2011-11-27 Jan Djärv <jan.h.d@swipnet.se>
12982 * gtkutil.c (xg_create_frame_widgets):

12993 Rename locals to avoid shadowing.
12994 * fileio.c (Finsert_file_contents):
12995 Rename inner 'gcpro1' to 'inner_gcpro1' to avoid shadowing.
12996 * process.c (wait_reading_process_output):
12997 Rename inner 'proc' to 'p' to avoid shadowing.
12998 Indent for consistency with usual Emacs style.
13000 2011-11-25 Eli Zaretskii <eliz@gnu.org>
13002 * xdisp.c (redisplay_window): If cursor row is not fully visible
13003 after recentering, and scroll-conservatively is set to a large
13004 number, scroll window by a few more lines to make the cursor fully
13005 visible and out of scroll-margin. (Bug#10105)
13006 (start_display): Don't move to the next line if the display should
13007 start at a newline that is part of a display vector or an overlay
13008 string. (Bug#10119)
13010 2011-11-24 Juri Linkov <juri@jurta.org>
13012 * image.c (imagemagick_load_image): Move `MagickSetResolution' down

13033 2011-11-22 Eli Zaretskii <eliz@gnu.org>
13035 * dispnew.c (adjust_glyph_matrix): Don't verify hash code of mode-
13036 and header-lines, as they don't have one computed for them.
13039 * .gdbinit (prow): Make displayed values more self-explaining.
13040 Add row's hash code.
13042 2011-11-21 Lars Magne Ingebrigtsen <larsi@gnus.org>

13085 2011-11-20 Paul Eggert <eggert@cs.ucla.edu>
13087 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
13088 Otherwise, valgrind does not work on some platforms.
13089 Problem reported by Andreas Schwab in
13090 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
13091 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
13092 is set, removing the need for VIRT_ADDRESS_VARIES.
13093 (PURE_P): Use a more-efficient implementation that needs just one
13094 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
13095 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
13096 to 4 (xorl, subq, cmpq, setbe).
13097 * alloc.c (pure): Always extern now, since that's the
13098 VIRT_ADDR_VARIES behavior.
13099 (PURE_POINTER_P): Use a single comparison, not two, for
13100 consistency with the new puresize.h.
13101 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
13102 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:
13103 Remove VIRT_ADDR_VARIES no longer needed.

13108 (erase_phys_cursor, update_window_cursor, show_mouse_face)
13109 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
13110 behave as if the cursor position were at the window margin.
13112 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
13113 and the cursor position is out of bounds, behave as if the cursor
13114 position were at the window margin. (Bug#10075)
13116 2011-11-18 Chong Yidong <cyd@gnu.org>
13118 * window.c (Fwindow_combination_limit): Make first argument
13119 non-optional, since it is meaningless for live windows like the

13131 2011-11-18 Eli Zaretskii <eliz@gnu.org>
13133 * dispnew.c (swap_glyph_pointers): Swap the used[] arrays and the
13134 hash values of the two rows.
13135 (copy_row_except_pointers): Preserve the used[] arrays and the
13136 hash values of the two rows. (Bug#10035)
13137 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
13139 * xdisp.c (row_hash): New function, body extracted from
13140 compute_line_metrics.
13141 (compute_line_metrics): Call row_hash, instead of computing the
13144 * dispnew.c (verify_row_hash): Call row_hash for computing the
13145 hash code of a row, instead of duplicating code from xdisp.c.
13147 * dispextern.h (row_hash): Add prototype.
13149 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
13151 * frame.c (delete_frame): Don't delete the terminal when the last
13152 X frame is closed if emacs is built with GTK toolkit.

13173 * window.c (Fwindow_nest): Rename to Fwindow_combination_limit.
13174 (Fset_window_nest): Rename to Fset_window_combination_limit.
13175 (Vwindow_nest): Rename to Vwindow_combination_limit.
13176 (recombine_windows, make_parent_window, make_window)
13177 (Fsplit_window_internal, saved_window)
13178 (Fset_window_configuration, save_window_save): Rename all
13179 occurrences of window_nest to window_combination_limit.
13181 2011-11-15 Juanma Barranquero <lekktu@gmail.com>
13183 * image.c (imagemagick_load_image): Fix typo.
13185 2011-11-14 Eli Zaretskii <eliz@gnu.org>
13187 * xdisp.c (display_line): Move the call to
13188 highlight_trailing_whitespace before the call to
13189 compute_line_metrics, since the latter needs to see the final
13190 faces of all the glyphs to compute ROW's hash value.
13191 Fixes assertion violations in row_equal_p. (Bug#10035)
13193 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
13195 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
13196 just return (bug#10044).
13198 2011-11-12 Eli Zaretskii <eliz@gnu.org>
13200 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
13201 with user-defined heap size. Bump the default size of the temacs
13202 heap to 27MB, to avoid memory warning when running temacs.
13203 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
13205 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
13206 current_matrix and desired_matrix. (Bug#9990)
13207 (verify_row_hash) [XASSERTS]: New function.
13208 (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify
13209 that the hash value of glyph rows is correct.

13225 * nsfns.m (unwind_create_frame):
13226 * w32fns.c (unwind_create_frame): Use Fmemq to check if frame is in
13227 Vframe_list (Bug#9999).

13238 2011-11-11 Johan Bockgård <bojohan@gnu.org>
13240 * xdisp.c (fill_composite_glyph_string): Always set s->face, to
13241 avoid a crash (bug#9496).
13243 2011-11-09 Chong Yidong <cyd@gnu.org>
13245 * window.c (Fwindow_inside_edges, Fwindow_inside_pixel_edges)

13252 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
13254 Avoid some portability problems by eschewing 'extern inline' functions.
13255 The trivial performance wins aren't worth the portability hassles; see
13256 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
13258 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
13259 (window_box_width, window_box_left, window_box_left_offset)
13260 (window_box_right, window_box_right_offset): Undo previous change,
13261 by removing the "extern"s.
13262 * intervals.c (adjust_intervals_for_insertion)
13263 (adjust_intervals_for_deletion): Undo previous change,
13264 making these static again.
13265 (offset_intervals, temp_set_point_both, temp_set_point)
13266 (copy_intervals_to_string): No longer inline.
13267 * xdisp.c (window_text_bottom_y, window_box_width)
13268 (window_box_height, window_box_left_offset)
13269 (window_box_right_offset, window_box_left, window_box_right)
13270 (window_box): No longer inline.

13295 * window.c (Fwindow_nest, Fset_window_nest)
13296 (Fset_window_new_total, Fset_window_new_normal)
13297 (Fwindow_resize_apply): Don't use term subwindow in doc-strings.
13298 (delete_all_subwindows): Rename to delete_all_child_windows.
13299 (Fdelete_other_windows_internal, Fset_window_configuration):
13300 Call delete_all_child_windows instead of delete_all_subwindows.
13301 * frame.c (delete_frame): Call delete_all_child_windows instead
13302 of delete_all_subwindows.
13304 2011-11-07 Paul Eggert <eggert@cs.ucla.edu>
13306 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
13307 This is also needed for porting to any host where GC_MARK_STACK is
13308 not GC_MAKE_GCPROS_NOOPS.
13309 (which_symbols): Use it.
13311 2011-11-07 Kenichi Handa <handa@m17n.org>
13313 * coding.c (coding_set_destination): Check coding->src_pos only
13314 when coding->src_object is a buffer (bug#9910).

13320 process_coding to 0 (bug#9912).
13322 2011-11-06 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13324 * xmenu.c (cleanup_widget_value_tree): New function.
13325 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
13326 calling free_menubar_widget_value_tree directly (Bug#9830).
13328 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
13330 Fix some portability problems with 'inline'.
13331 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
13332 (window_box_width, window_box_left, window_box_left_offset)
13333 (window_box_right, window_box_right_offset): Declare extern.
13334 Otherwise, these inline functions do not conform to C99 and
13335 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
13336 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
13337 * intervals.c (adjust_intervals_for_insertion)
13338 (adjust_intervals_for_deletion): Now extern, because otherwise the
13339 extern inline functions 'offset_intervals' couldn't refer to it.
13340 (static_offset_intervals): Remove.
13341 (offset_intervals): Rewrite using the old contents of
13342 static_offset_intervals. The old version didn't conform to C99
13343 because an extern inline function contained a reference to an
13344 identifier with static linkage.
13346 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
13348 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

13353 * xdisp.c (init_iterator, reseat_to_string): Don't set the
13354 iterator's bidi_p flag if Vpurify_flag is non-nil. (Bug#9963)
13355 (Fcurrent_bidi_paragraph_direction): If Vpurify_flag is non-nil,
13356 return Qleft_to_right.

13363 (Fwindow_use_time, Fwindow_total_size, Fwindow_normal_size)
13364 (Fwindow_new_normal, Fwindow_left_column, Fwindow_top_line)
13365 (Fwindow_margins, Fwindow_fringes, Fwindow_scroll_bars)
13366 (Fwindow_vscroll): Doc fix.
13367 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
13368 argument, since it makes no sense to pass a live window and for
13369 consistency with window-child.

13579 (w32font_open_internal, compute_metrics):
13580 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
13581 instead of calling the "wide" APIs directly.
13583 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
13585 * w32.h (syms_of_w32font): Add prototype.

13596 * process.c (make_process): Set gnutls_state to NULL.
13598 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
13599 non-NULL, regardless of GNUTLS_INITSTAGE.

13634 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
13636 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>

13639 terminal (Bug#6649).
13641 2011-10-20 Eli Zaretskii <eliz@gnu.org>
13643 * dispextern.h (struct bidi_it): New member next_en_type.
13645 * bidi.c (bidi_line_init): Initialize the next_en_type member.
13646 (bidi_resolve_explicit_1): When next_en_pos is valid for the
13647 current character, check also for next_en_type being WEAK_EN.
13648 (bidi_resolve_weak): Don't enter the expensive loop if the current
13649 position is before next_en_pos. Record the bidi type of the first
13650 non-ET, non-BN character we find, in addition to its position.
13651 (bidi_level_of_next_char): Invalidate next_en_type when
13652 next_en_pos is over-stepped.
13654 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
13656 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
13657 * editfns.c: Rewrite current-time-zone so that it invokes
13658 the equivalent of (format-time-string "%Z") to get the time zone name.
13659 This fixes a bug when the time zone name contains characters that
13660 need converting from the system time locale to Emacs internal format.
13661 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
13662 that patch fixed format-time-string to do the conversion, but
13663 I forgot to fix current-time-zone.
13664 (format_time_string): New function, containing most of
13665 what Fformat_time_string used to contain.
13666 (Fformat_time_string): Rewrite in terms of format_time_string.
13667 This doesn't change this function's behavior.
13668 (current-time-zone): Rewrite to use format_time_string.
13669 This fixes the bug reported by Michael Schierl in
13670 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
13671 Jason Rumney's 2007-06-07 change worked around this bug, but
13673 * systime.h (tzname, timezone): Remove no-longer-used declarations.
13675 2011-10-19 Eli Zaretskii <eliz@gnu.org>
13677 * xdisp.c (start_display): If the character at POS is displayed
13678 via a display vector, reset IT->current.dpvec_index to zero.
13679 (try_window_reusing_current_matrix): If a line ends in a display
13680 vector or the next line starts in a display vector, continue
13681 redrawing the window even though the character position of
13682 start_row was reached.
13685 2011-10-18 Chong Yidong <cyd@gnu.org>
13687 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
13688 with nobreak-char-display too.
13690 2011-10-18 Eli Zaretskii <eliz@gnu.org>
13692 Fix part 3 of bug#9771.
13693 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
13694 (bidi_resolve_neutral): Don't enter the expensive loop looking for
13695 non-neutral characters if the current character is a paragraph
13696 separator (a.k.a. Newline). This avoids running the same
13697 expensive loop twice, once when we consume the preceding newline
13698 and the other time when the line actually needs to be displayed.
13699 Avoid the loop when we see neutrals on the base embedding level
13700 following a character whose directionality is the same as the
13701 paragraph's. This avoids running the expensive loop when a line
13702 ends in a long sequence of neutrals, like control characters.
13703 Add assertion against STRONG_AL type. Slightly rearrange code
13704 that determines the type of a neutral given the first non-neutral
13706 (bidi_level_of_next_char): Set next_en_pos to zero when
13707 invalidating its info.
13709 2011-10-17 Eli Zaretskii <eliz@gnu.org>
13711 * xdisp.c (push_display_prop): Determine whether to record string
13712 or buffer position by IT->string, not by IT->method. Allow
13713 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
13714 (move_it_vertically_backward): Don't look for character position
13715 immediately after the newline when in a continuation line.
13718 2011-10-15 Martin Rudalics <rudalics@gmx.at>
13720 * window.c (coordinates_in_window): Rewrite and delabelize
13721 vertical border check. (Bug#5357) (Bug#9618)
13723 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
13725 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
13726 errors in XSetWindowBorder (bug#9310).
13728 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
13730 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
13731 avoid crash when xmalloc overrun checking is enabled.
13733 2011-10-13 Eli Zaretskii <eliz@gnu.org>
13735 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
13736 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
13737 cursor motion with <left> and <right> arrow keys.
13739 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
13740 some callers set that themselves.
13742 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13744 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
13745 display string and the previous row comes from the same string and
13746 is empty. (Bug#9739) (Bug#9738)
13748 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
13750 * doc.c (get_doc_string): Encode file name (bug#9735).
13752 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13754 * bidi.c (bidi_level_of_next_char):
13755 * xdisp.c (get_visually_first_element): Remove old incorrect
13756 comments regarding the Unicode Line Separator character.
13758 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
13760 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
13762 * alloc.c (Fgc_status): Do not access beyond zombies array
13763 boundary if nzombies > MAX_ZOMBIES.
13764 * alloc.c (dump_zombies): Add missing format specifier.
13766 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
13768 * xdisp.c (set_cursor_from_row): Simplify conditionals,
13769 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
13771 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
13772 Some packages use them to denote characters with modifiers.
13774 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
13776 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
13777 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
13778 matching a pp-number. Rename parameter var to var1.
13780 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
13782 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
13784 2011-10-08 Glenn Morris <rgm@gnu.org>
13786 * callint.c (Fcall_interactively): Give a more explicit error for the
13787 'c' case with a non-character input. (Bug#8479)
13789 2011-10-08 Eli Zaretskii <eliz@gnu.org>
13791 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
13793 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
13794 lines that are hscrolled on the left.

13802 Don't advertise functionality which we discourage or doesn't work.
13804 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
13806 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
13807 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
13808 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
13809 this makes Emacs dump core during garbage collection on rare
13810 occasions. sizeof is obviously inferior to offsetof here, so
13811 stick with offsetof.
13812 (GC_POINTER_ALIGNMENT): New macro.
13813 (mark_memory): Omit 3rd (offset) arg; caller changed.
13814 Don't assume EMACS_INT alignment is the same as pointer alignment.
13816 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
13818 * keyboard.c (read_key_sequence_remapped): New var.
13819 (read_key_sequence): Compute remapping in the right buffer.
13820 (command_loop_1): Use read_key_sequence's remapping directly.
13822 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
13824 * dired.c (file_name_completion): Don't expand file name.
13825 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
13826 before checking file name handler.
13828 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
13829 they've been requested explicitly (bug#9591).
13831 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
13833 * keymap.c (Fsingle_key_description): Use make_specified_string
13834 instead of build_string to build string from push_key_description.
13837 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13839 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
13840 This fixes a Y2038 bug on 64-bit hosts.
13841 * buffer.c (reset_buffer):
13842 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
13843 (Fclear_buffer_auto_save_failure):
13844 Use 0, not -1, to represent an unset failure time, since time_t
13845 might not be signed.
13847 Remove dependency on glibc malloc internals.
13848 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13849 Move back here from lisp.h, but with their new implementations.
13850 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13851 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
13852 * charset.c (charset_table_init): New static var.
13853 (syms_of_charset): Use it instead of xmalloc. This removes a
13854 dependency on glibc malloc internals. See Eli Zaretskii's comment in
13855 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
13856 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13857 Move back to alloc.c.
13858 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13859 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
13861 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
13863 * nsterm.m (windowDidResize): Call x_set_window_size only when
13864 ns_in_resize is true. Otherwise set pixelwidth/height and
13865 call change_frame_size (Bug#9628).
13867 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13869 Port --enable-checking=all to Fedora 14 x86-64.
13870 * charset.c (syms_of_charset): Also account for glibc malloc's
13871 internal overhead when calculating the initial malloc maximum.
13873 Port --enable-checking=all to Fedora 14 x86.
13874 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13876 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
13877 (overrun_check_realloc, overrun_check_free):
13878 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
13879 That way, xmalloc returns a properly-aligned pointer even if
13880 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
13881 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
13882 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
13883 into account when calculating the initial malloc maximum.
13884 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13885 Move here from alloc.c, so that charset.c can use it too.
13886 Properly align; the old code wasn't right for common 32-bit hosts
13887 when configured with --enable-checking=all.
13888 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13889 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
13891 2011-09-29 Eli Zaretskii <eliz@gnu.org>
13893 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
13896 2011-09-28 Eli Zaretskii <eliz@gnu.org>
13898 * xdisp.c (compute_display_string_end): If there's no display
13899 string at CHARPOS, return -1.
13901 * bidi.c (bidi_fetch_char): When compute_display_string_end
13902 returns a negative value, treat the character as a normal
13903 character not covered by a display string. (Bug#9624)
13905 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
13907 * lread.c (Fread_from_string): Fix typo in docstring.
13909 2011-09-27 Eli Zaretskii <eliz@gnu.org>
13911 * xdisp.c (handle_invisible_prop): If invisible text ends on a
13912 newline, reseat the iterator instead of bidi-iterating there one
13913 character at a time. (Bug#9610)
13914 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
13915 TO_CHARPOS if the bidi iterator is at base embedding level.
13917 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
13919 * lread.c (readevalloop): Use correct code for NBSP.
13920 (read1): Likewise. (Bug#9608)
13922 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
13924 * dbusbind.c (Fdbus_register_signal): When service is not
13925 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
13927 2011-09-25 Glenn Morris <rgm@gnu.org>
13929 * buffer.c (truncate-lines): Doc fix.
13931 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
13933 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
13934 (Fset_window_next_buffers): Doc fix.
13936 2011-09-24 Glenn Morris <rgm@gnu.org>
13938 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
13940 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
13942 Fix minor problems found by static checking.
13943 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
13944 * indent.c (Fvertical_motion): Fix == vs = typo.
13946 2011-09-24 Eli Zaretskii <eliz@gnu.org>
13948 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
13949 Default value is now t. Doc fix.
13951 * indent.c (Fvertical_motion): Compute and apply the overshoot
13952 logic when moving up, not only when moving down. Fix the
13953 confusing name and values of the it_overshoot_expected variable;
13954 logic changes accordingly. (Bug#9254) (Bug#9549)
13956 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
13957 CHARPOS is covered by a display string which includes newlines.
13958 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
13959 is covered by a display string with embedded newlines.
13961 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
13963 * dbusbind.c (Fdbus_register_signal): Add match rule to
13964 Vdbus_registered_objects_table. (Bug#9581)
13965 (Fdbus_register_method, Vdbus_registered_objects_table):
13968 2011-09-24 Jim Meyering <meyering@redhat.com>
13970 do not ignore write error for any output size
13971 The previous change was incomplete.
13972 While it makes emacs --batch detect the vast majority of stdout
13973 write failures, errors were still ignored whenever the output size is
13974 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
13975 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
13976 && echo FAIL: ignored write error
13977 FAIL: ignored write error
13978 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
13979 && echo FAIL: ignored write error
13980 FAIL: ignored write error
13981 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
13983 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
13985 * emacs.c (Fkill_emacs): In noninteractive mode exit
13986 non-successfully if a write error occurred on stdout. (Bug#9574)
13988 2011-09-21 Eli Zaretskii <eliz@gnu.org>
13990 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
13993 * dispextern.h (struct it): Update the comment documenting what
13996 2011-09-20 Eli Zaretskii <eliz@gnu.org>
13998 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
13999 a display string, extend search for cursor position to end of row.
14000 (find_row_edges): If the row ends in a newline from a display
14001 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
14002 Handle the case of a display string with multiple newlines.
14003 (Fcurrent_bidi_paragraph_direction): Fix search for previous
14004 non-empty line. Fixes confusing cursor motion with arrow keys at
14005 the beginning of a line that starts with whitespace.
14007 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14009 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
14012 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
14014 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
14015 boolean (Bug#9154).
14017 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14019 * xdisp.c (display_line): Record maximum and minimum buffer
14020 positions even if no glyphs were produced (e.g., by a zero-width
14021 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
14022 buffer positions that will be removed from the glyph row because
14024 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
14025 column is beyond frame width: don't subtract 1 "pixel" when
14026 computing width of the stretch.
14027 (reseat_at_next_visible_line_start): Undo the change made on
14028 2011-09-17 that saved paragraph information and restored it after
14029 the call to `reseat'. (Bug#9545)
14031 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14033 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
14034 and turn window cursor on if cleared (Bug#9415).
14036 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
14038 * search.c (boyer_moore): Take unibyte characters from pattern
14039 literally. (Bug#9458)
14041 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14043 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
14045 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
14047 Fix minor problem found by static checking.
14048 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
14049 initialized, to pacify gcc -Wuninitialized.
14051 * fileio.c: Report proper errno when syscall falls.
14052 (Finsert_file_contents): Save and restore errno,
14053 so that report_file_error outputs the correct diagnostic.
14054 (Fwrite_region) [CLASH_DETECTION]: Likewise.
14056 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14058 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
14060 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14062 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
14063 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
14065 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14067 * xdisp.c (reseat_at_next_visible_line_start): Keep information
14068 about the current paragraph and restore it after the call to reseat.
14070 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
14071 (bidi_find_paragraph_start): Search back for paragraph beginning
14072 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
14073 (bidi_move_to_visually_next): Only trigger paragraph-related
14074 computations when the last character is a newline or at EOB, not
14075 just any NEUTRAL_B. (Bug#9470)
14077 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
14078 truncated lines if point is covered by a display string. (Bug#9524)
14080 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
14082 * xselect.c: Relax test for outgoing X longs (Bug#9498).
14083 (cons_to_x_long): New function.
14084 (lisp_data_to_selection_data): Use it. Correct the test for
14085 short-versus-long data; it was negated. Break out of vector
14086 loop, for efficiency, when a long datum is discovered.
14088 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
14090 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
14092 2011-09-16 Eli Zaretskii <eliz@gnu.org>
14094 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
14095 GCC PR/17406) by declaring this function with external scope.
14097 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14099 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
14100 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
14102 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
14104 * editfns.c (Fformat): Correctly handle text properties on "%%".

14110 * term.c (encode_terminal_code):
14111 * composite.c (composition_update_it, get_composition_id):
14112 * xdisp.c (get_next_display_element)
14113 (fill_composite_glyph_string): Add comments about special meaning
14114 of TAB characters in a composition.
14116 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14118 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
14119 This occurs when processing a multibyte format.
14120 Problem reported by Wolfgang Jenker.
14122 2011-09-15 Johan Bockgård <bojohan@gnu.org>
14124 * xdisp.c (try_cursor_movement): Only check for exact match if
14125 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
14127 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14129 Remove unused external symbols.
14130 * dispextern.h (calc_pixel_width_or_height): Remove decl.
14131 * xdisp.c (calc_pixel_width_or_height): Now static.
14132 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
14133 * indent.c (check_display_width):
14134 * w32term.c: Fix comment to match code.
14135 * xterm.c, xterm.h (x_catching_errors): Remove.
14137 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14139 * xselect.c: Use signed conversions more consistently (Bug#9498).
14140 (selection_data_to_lisp_data): Assume incoming selection data are
14141 signed integers, not unsigned. This is to be consistent with
14142 outgoing selection data, which was modified to use signed integers
14143 in as part of the fix to Bug#9196 in response to Jan D.'s comment
14144 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
14145 expects long, not unsigned long.
14147 2011-09-14 Eli Zaretskii <eliz@gnu.org>
14149 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
14150 computation of loop end. Reported by Johan Bockgård
14153 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
14155 * frame.c (Fother_visible_frames_p): Function deleted.
14157 2011-09-12 Eli Zaretskii <eliz@gnu.org>
14159 * indent.c (compute_motion): Process display vector front to back
14160 rather than the other way around. (Bug#2496)
14162 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
14164 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
14166 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
14168 * minibuf.c (Fread_from_minibuffer): Doc fix.
14170 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14172 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
14173 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
14175 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
14177 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
14178 value for non-existent files.
14180 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14182 * fileio.c (Finsert_file_contents): If the file cannot be opened,
14183 set its "size" to -1. This will set the modtime_size field of
14184 the corresponding buffer to -1, which is what
14185 verify-visited-file-modtime expects for files that do not exist.
14188 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
14190 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
14192 * lisp.h: ... from here. push_key_description is no longer
14193 defined in keyboard.c, so its declaration should not be in
14194 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
14195 logically belongs with push_key_description.
14197 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
14199 * buffer.h: Include <sys/types.h> instead of <time.h>.
14200 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
14201 Problem reported by Herbert J. Skuhra.
14203 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
14205 * xml.c (parse_region): Make the parsing work for
14206 non-comment-starting XML files again (bug#9144).
14208 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
14210 * image.c (gif_load): Fix calculation of bottom and right corner.
14213 2011-09-10 Eli Zaretskii <eliz@gnu.org>
14215 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
14216 redisplay in small windows.
14218 2011-09-09 Eli Zaretskii <eliz@gnu.org>
14220 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
14222 2011-09-08 Martin Rudalics <rudalics@gmx.at>
14224 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
14225 Operate on live windows only.
14227 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
14229 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
14231 2011-09-07 Eli Zaretskii <eliz@gnu.org>
14233 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
14234 only under bidi iteration.
14236 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
14238 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
14240 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14242 isnan: Fix porting problem to Solaris 10 with bundled gcc.
14243 Without this fix, the command to link temacs failed due to an
14244 undefined symbol __builtin_isnan. This is because
14245 /usr/include/iso/math_c99.h #defines isnan(x) to
14246 __builtin_isnan(x), but the bundled gcc, which identifies itself
14247 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
14249 * floatfns.c (isnan): #undef, and then #define to a clone of
14251 (Fisnan): Always define, since it's always available now.
14252 (syms_of_floatfns): Always define isnan at the Lisp level.
14254 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14256 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
14258 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14260 * fileio.c: Fix bugs with large file offsets (Bug#9428).
14261 The previous code assumed that file offsets (off_t values) fit in
14262 EMACS_INT variables, which is not true on typical 32-bit hosts.
14263 The code messed up by falsely reporting buffer overflow in cases
14264 such as (insert-file-contents "big" nil 1 2) into an empty buffer
14265 when "big" contains more than 2**29 bytes, even though this
14266 inserts just one byte and does not overflow the buffer.
14267 (Finsert_file_contents): Store file offsets as off_t
14268 values, not as EMACS_INT values. Check for overflow when
14269 converting between EMACS_INT and off_t. When checking for
14270 buffer overflow or for overlap, take the offsets into account.
14271 Don't use EMACS_INT for small values where int suffices.
14272 When checking for overlap, fix a typo: ZV was used where
14273 ZV_BYTE was intended.
14274 (Fwrite_region): Don't assume off_t fits into 'long'.
14275 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
14277 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
14279 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
14281 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14283 sprintf-related integer and memory overflow issues (Bug#9412).
14285 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
14286 (esprintf, exprintf, evxprintf): New functions.
14287 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
14288 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
14289 (modify_event_symbol): Do not assume that the length of
14290 name_alist_or_stem is safe to alloca and fits in int.
14291 (Fexecute_extended_command): Likewise for function name and binding.
14292 (Frecursion_depth): Wrap around reliably on integer overflow.
14293 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
14294 since some callers pass EMACS_INT values.
14295 (Fsingle_key_description): Don't crash if symbol name contains more
14296 than MAX_ALLOCA bytes.
14297 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
14298 (get_minibuffer): Arg is now EMACS_INT, not int.
14299 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
14300 (esprintf, exprintf, evxprintf): New decls.
14301 * window.h (command_loop_level, minibuf_level): Reflect API changes.
14303 * dbusbind.c (signature_cat): New function.
14304 (xd_signature, Fdbus_register_signal):
14305 Do not overrun buffer; instead, report string overflow.
14307 * dispnew.c (add_window_display_history): Don't overrun buffer.
14308 Truncate instead; this is OK since it's just a log.
14310 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
14311 even if the time zone offset is outlandishly large.
14312 Don't mishandle offset == INT_MIN.
14314 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
14315 when creating daemon; the previous buffer-overflow check was incorrect.
14317 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
14318 which has the guts of the old verror function.
14320 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
14321 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
14323 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
14324 (font_unparse_xlfd): Don't blindly alloca long strings.
14325 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
14326 fits in int, when using sprintf. Use single snprintf to count
14327 length of string rather than counting it via multiple sprintfs;
14328 that's simpler and more reliable.
14329 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
14330 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
14331 sprintf, in case result does not fit in int.
14333 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
14334 (fontset_from_font): Print it.
14336 * frame.c (tty_frame_count): Now printmax_t, not int.
14337 (make_terminal_frame, set_term_frame_name): Print it.
14338 (x_report_frame_params): In X, window IDs are unsigned long,
14339 not signed long, so print them as unsigned.
14340 (validate_x_resource_name): Check for implausibly long names,
14341 and don't assume name length fits in 'int'.
14342 (x_get_resource_string): Don't blindly alloca invocation name;
14343 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
14346 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
14347 (xg_check_special_colors, xg_set_geometry):
14348 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
14350 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
14351 Use esprintf, not sprintf, in case result does not fit in int.
14353 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14354 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
14355 it as a large positive number.
14356 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
14357 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14359 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
14360 in case result does not fit in int.
14362 * print.c (float_to_string): Detect width overflow more reliably.
14363 (print_object): Make sprintf buffer a bit bigger, to avoid potential
14364 buffer overrun. Don't assume list length fits in 'int'. Treat
14365 print length of 0 as 0, not as infinity; to be consistent with other
14366 uses of print length in this function. Don't overflow print length
14367 index. Don't assume hash table size fits in 'long', or that
14368 vectorlike size fits in 'unsigned long'.
14370 * process.c (make_process): Use printmax_t, not int, to format
14371 process-name gensyms.
14373 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
14375 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
14376 to avoid potential buffer overrun.
14378 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
14379 if X resource line is longer than 512 bytes.
14381 * xfns.c (x_window): Make sprintf buffer a bit bigger
14382 to avoid potential buffer overrun.
14384 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
14386 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
14388 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14390 Integer overflow fixes for scrolling, etc.
14391 Without these, Emacs silently mishandles large integers sometimes.
14392 For example, "C-u 4294967297 M-x recenter" was treated as if
14393 it were "C-u 1 M-x recenter" on a typical 64-bit host.
14395 * xdisp.c (try_window_id): Check Emacs fixnum range before
14396 converting to 'int'.
14398 * window.c (window_scroll_line_based, Frecenter):
14399 Check that an Emacs fixnum is in range before assigning it to 'int'.
14400 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
14401 values converted from Emacs fixnums.
14402 (Frecenter): Don't wrap around a line count if it is out of 'int'
14403 range; instead, treat it as an extreme value.
14404 (Fset_window_configuration, compare_window_configurations):
14405 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
14407 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
14408 that can exceed INT_MAX. Check that EMACS_INT value is in range
14409 before assigning it to the (possibly-narrower) index.
14410 (match_limit): Don't assume that a fixnum can fit in 'int'.
14412 * print.c (print_object): Use ptrdiff_t, not int, for index that can
14415 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
14416 (Fvertical_motion): Don't wrap around LINES values that don't fit
14417 in 'int'. Instead, treat them as extreme values. This is good
14418 enough for windows, which can't have more than INT_MAX lines anyway.
14420 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
14422 * Require libxml/parser.h to avoid compilation warning.
14424 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
14426 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
14427 since this reportedly can destroy thread storage.
14429 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
14431 * syntax.c (find_defun_start): Update all cache variables if
14432 exiting early (Bug#9401).
14434 2011-08-30 Eli Zaretskii <eliz@gnu.org>
14436 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
14438 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
14439 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
14440 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
14442 * term.c (tty_append_glyph): New function.
14443 (produce_stretch_glyph): Static function and its prototype deleted.
14445 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
14448 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
14450 * image.c (parse_image_spec): Check for nonnegative, not for positive,
14451 when checking :margin (Bug#9390).
14452 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
14453 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
14454 so that the name doesn't mislead. All uses changed.
14456 2011-08-28 Johan Bockgård <bojohan@gnu.org>
14458 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
14461 2011-08-27 Eli Zaretskii <eliz@gnu.org>
14463 * xdisp.c (move_it_to): Don't bail out early when reaching
14464 position beyond to_charpos, if we are scanning backwards.
14465 (move_it_vertically_backward): When DY == 0, make sure we get to
14466 the first character in the line after the newline.
14468 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
14470 * ccl.c: Improve and simplify overflow checking (Bug#9196).
14471 (ccl_driver): Do not generate an out-of-range pointer.
14472 (Fccl_execute_on_string): Remove unnecessary check for
14473 integer overflow, noted by Stefan Monnier in
14474 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
14475 Remove a FIXME that didn't need fixing.
14476 Simplify the newly-introduced buffer reallocation code.
14478 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
14480 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
14482 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
14484 Integer and memory overflow issues (Bug#9196).
14486 * doc.c (get_doc_string): Rework so that
14487 get_doc_string_buffer_size is the actual buffer size, rather than
14488 being 1 less than the actual buffer size; this makes xpalloc more
14491 * image.c (x_allocate_bitmap_record, cache_image):
14492 * xselect.c (Fx_register_dnd_atom):
14493 Simplify previous changes by using xpalloc.
14495 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
14496 since either will do and ptrdiff_t is convenient with xpalloc.
14498 * charset.c (charset_table_size)
14499 (struct charset_sort_data.priority): Now ptrdiff_t.
14500 (charset_compare): Don't overflow if priorities differ greatly.
14501 (Fsort_charsets): Don't assume list length fits in int.
14502 Check for size-calculation overflow when allocating sort data.
14503 (syms_of_charset): Allocate an initial charset table that is
14504 just under 64 KiB, to avoid problems with glibc malloc and mmap.
14506 * cmds.c (internal_self_insert): Check for size-calculation overflow.
14508 * composite.h (struct composition.glyph_len): Now int, not unsigned.
14509 The actual value is always <= INT_MAX, and leaving it unsigned made
14510 overflow checking harder.
14512 * dispextern.h (struct glyph_matrix.rows_allocated)
14513 (struct face_cache.size): Now ptrdiff_t, for convenience in use
14514 with xpalloc. The values are still always <= INT_MAX.
14516 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
14518 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
14519 (SAFE_NALLOCA): New macro.
14521 * region-cache.c (struct boundary.pos, find_cache_boundary)
14522 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
14523 (set_cache_region, invalidate_region_cache)
14524 (revalidate_region_cache, know_region_cache, region_cache_forward)
14525 (region_cache_backward, pp_cache):
14526 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
14527 so that ptrdiff_t * can be passed to xpalloc.
14528 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
14529 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
14530 (pp_cache): Don't assume cache_len fits in int.
14531 * region-cache.h: Adjust extern decls to match.
14533 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
14534 EMACS_INT, since either will do, for xpalloc.
14536 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
14537 (xnmalloc, xnrealloc, xpalloc): New functions.
14539 * bidi.c (bidi_shelve_header_size): New constant.
14540 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
14541 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
14543 * bidi.c (bidi_cache_shrink):
14544 * buffer.c (overlays_at, overlays_in, record_overlay_string)
14546 Don't update size of array until after memory allocation succeeds,
14547 because xmalloc/xrealloc may not return.
14548 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
14549 now that we have proper integer overflow checking.
14550 (record_overlay_string, overlay_strings): Catch overflows when
14551 calculating size of overlay_str_buf.
14553 * callproc.c (Fcall_process): Check for size overflow when
14554 calculating size of args2.
14555 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
14556 Normally we prefer signed values, but sticking with ptrdiff_t would
14557 require adding more-complicated checks.
14559 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
14560 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
14561 Redo buffer-overflow calculations to avoid integer overflow.
14562 Add a FIXME comment where memory seems to be over-allocated.
14564 * character.c (Fstring): Check for size-calculation overflow.
14566 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
14567 unnecessary integer overflow. Check for size overflow.
14568 (encode_coding_object): Don't update size until xmalloc succeeds.
14570 * composite.c (get_composition_id): Check for overflow in glyph
14571 length calculations.
14573 Integer and memory overflow fixes for display code.
14574 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
14575 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
14576 (scrolling_window): Check for overflow in size calculations.
14577 (line_draw_cost, realloc_glyph_pool, add_row_entry):
14578 Don't assume glyph table len fits in int.

14580 (row_table_size): Now ptrdiff_t, not int.
14581 (scrolling_window): Avoid overflow in size calculations.
14582 Don't update size until allocation succeeds.
14583 * fns.c (concat): Check for overflow in size calculations.
14584 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
14585 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
14586 (NEXT_ALMOST_PRIME_LIMIT): New constant.
14588 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
14589 (get_doc_string): Check for size calculation overflow.
14590 Don't update size until allocation succeeds.
14591 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
14592 EMACS_INT, where ptrdiff_t will do.
14593 (Fsubstitute_command_keys): Check for string overflow.
14595 * editfns.c (set_time_zone_rule): Don't assume environment length
14597 (message_length): Now ptrdiff_t, not int.
14598 (Fmessage_box): Don't update size until allocation succeeds.
14599 Don't assume message length fits in int.
14600 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
14602 * emacs.c (main): Do not reallocate argv, since there is a null at
14603 the end that can be overwritten, and this way there's no need to
14604 worry about size-calculation overflow.
14605 (sort_args): Check for size-calculation overflow.
14607 * eval.c (init_eval_once, grow_specpdl): Don't update size until
14609 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
14611 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
14612 (x_set_scroll_bar_width, x_figure_window_size):
14613 Check for integer overflow.
14614 (x_set_alpha): Do not assume XINT fits in int.
14616 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
14617 This is for the members text_lines, text_cols, total_lines, total_cols,
14618 where the system imposes an 'int' limit.
14620 * fringe.c (Fdefine_fringe_bitmap):
14621 Don't update size until alloc works.
14623 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
14624 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
14626 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
14627 Check for size-calculation overflow.
14628 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
14629 do, as we prefer signed integers.
14630 (id_to_widget.max_size, id_to_widget.used)
14631 (xg_store_widget_in_map, xg_remove_widget_from_map)
14632 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
14633 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
14634 Use and return ptrdiff_t, not int.
14635 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
14636 * gtkutil.h: Change prototypes to match the above.
14638 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
14639 are duplicate now that they've been promoted to lisp.h.
14640 (x_allocate_bitmap_record, x_alloc_image_color)
14641 (make_image_cache, cache_image, xpm_load):
14642 Don't update size until alloc is done.
14643 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)

14647 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
14650 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
14651 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
14652 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
14653 Use ptrdiff_t, not int, to count maps.
14654 (read_char_minibuf_menu_prompt): Check for overflow in size
14655 calculations. Don't update size until allocation succeeds.
14656 Redo calculations to avoid overflow.
14657 * keyboard.h: Change prototypes to match the above.
14659 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
14661 (current_minor_maps): Check for size calculation overflow.
14662 * keymap.h: Change prototypes to match the above.
14664 * lread.c (read1, init_obarray): Don't update size until alloc done.
14666 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
14667 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
14669 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
14670 Now ptrdiff_t, not int.

14685 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
14686 for command line length. Do not attempt to address one before the
14687 beginning of an array, as that's not portable.
14689 * term.c (max_frame_lines): Remove; unused.
14690 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
14692 (encode_terminal_code, calculate_costs): Check for size
14693 calculation overflow.
14694 (encode_terminal_code): Use ptrdiff_t, not int, to record glyph
14695 table lengths and related sizes. Don't update size until alloc
14696 done. Redo calculations to avoid overflow.
14697 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
14699 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of

14711 Use ptrdiff_t, not int, for sizes.
14712 (store_mode_line_noprop_char): Don't update size until alloc done.
14714 * xfaces.c (lface_id_to_name_size, Finternal_make_lisp_face):
14715 Use ptrdiff_t, not int, for sizes.
14716 (Finternal_make_lisp_face, cache_face):
14717 Check for size calculation overflow.
14718 (cache_face): Treat size calculation overflows as if they were
14719 memory exhaustion (the usual treatment), rather than aborting.
14721 * xfns.c (x_encode_text, x_set_name_internal)
14722 (Fx_change_window_property): Use ptrdiff_t, not int, to count
14723 sizes, since they can exceed INT_MAX in size. Check for size
14724 calculation overflow.
14726 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
14727 (xg_select): Check for size calculation overflow.
14728 Don't update size until alloc done.
14730 * xrdb.c (get_environ_db): Don't assume path length fits in int,
14731 as sprintf is limited to int lengths.
14733 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
14734 (X_LONG_MIN): New macros.
14735 Use them to make the following changes clearer.
14736 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
14737 This change doesn't affect the value now, but it may help remind
14738 future maintainers not to raise the value too much later.
14739 (SELECTION_QUANTUM): Remove, replacing with ...
14740 (selection_quantum): ... new function, which avoids overflow.
14742 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
14743 assumption that selection length fits in 'int'.
14744 (x_reply_selection_request, x_handle_selection_request)
14745 (x_get_window_property, receive_incremental_selection)
14746 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
14747 (lisp_data_to_selection_data, clean_local_selection_data):
14748 Use ptrdiff_t, not int, to record length of selection.
14749 (x_reply_selection_request, x_get_window_property)
14750 (receive_incremental_selection, x_property_data_to_lisp):
14751 Redo calculations to avoid overflow.
14752 (x_reply_selection_request): When sending hint, ceiling it at
14753 X_LONG_MAX rather than relying on wraparound overflow to send
14755 (x_get_window_property, receive_incremental_selection)
14756 (lisp_data_to_selection_data, x_property_data_to_lisp):
14757 Check for size-calculation overflow.
14758 (x_get_window_property, receive_incremental_selection)
14759 (lisp_data_to_selection_data, Fx_register_dnd_atom):
14760 Don't store size until memory allocation succeeds.
14761 (x_get_window_property): Plug memory leak on memory exhaustion.
14762 Don't double-block input; malloc is safe here. Don't assume 2**34
14763 - 4 fits in unsigned long. Add an xassert to check
14764 XGetWindowProperty overflow. Be more careful about overflow
14765 calculations, and distinguish size from memory overflow better.
14766 (receive_incremental_selection): When tracing, don't assume
14767 unsigned int is less than INT_MAX.
14768 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
14769 harmful) conversions of unsigned short to int.
14770 (lisp_data_to_selection_data): Don't assume that integers
14771 in the range -65535 through -1 fit in an X unsigned short.
14772 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
14773 result parameters unless successful. Rely on cons_to_unsigned
14774 to report problems with elements; the old code wasn't right anyway.
14775 (x_check_property_data): Check for int overflow; we cannot use
14776 a wider type due to X limits.
14777 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
14779 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
14781 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
14782 (x_term_init): Check for size calculation overflow.
14783 (x_color_cells): Don't store size until memory allocation succeeds.
14784 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
14785 Don't assume alloca size is less than MAX_ALLOCA.
14786 (x_term_init): Don't assume length fits in int (sprintf is limited
14789 Use ptrdiff_t for composition IDs.
14790 * character.c (lisp_string_width):
14791 * composite.c (composition_table_size, n_compositions)
14792 (get_composition_id, composition_gstring_from_id):
14793 * dispextern.h (struct glyph_string.cmp_id, struct composition_it.id):
14794 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING):
14795 * window.c (Frecenter):
14796 Use ptrdiff_t, not int, for composition IDs.
14797 * composite.c (get_composition_id): Check for integer overflow.
14798 * composite.h: Adjust prototypes to match the above changes.

14808 * image.c (xpm_get_color_table_h):
14809 * lisp.h (hash_lookup, hash_put):
14810 * minibuf.c (Ftest_completion):
14811 Use ptrdiff_t for hash table indexes, not int (which is too
14812 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
14813 32-bit --with-wide-int hosts).
14815 * charset.c (Fdefine_charset_internal): Check for integer overflow.
14816 Add a FIXME comment about memory leaks.
14817 (syms_of_charset): Don't assume xmalloc returns.
14819 Don't assume that stated character widths fit in int.
14820 * character.c (Fchar_width, c_string_width, lisp_string_width):
14821 * character.h (CHAR_WIDTH):
14822 * indent.c (MULTIBYTE_BYTES_WIDTH):
14823 Use sanitize_char_width to avoid undefined and/or bad behavior
14824 with outlandish widths.
14825 * character.h (sanitize_tab_width): Rename from sanitize_width,
14826 now that we have two such functions. All uses changed.
14827 (sanitize_char_width): New inline function.
14829 Don't assume that tab-width fits in int.
14830 * character.h (sanitize_width): New inline function.
14831 (SANE_TAB_WIDTH): New macro.
14832 (ASCII_CHAR_WIDTH): Use it.
14833 * indent.c (sane_tab_width): Remove. All uses replaced by
14834 SANE_TAB_WIDTH (current_buffer).
14835 * xdisp.c (init_iterator): Use SANE_TAB_WIDTH.
14837 * fileio.c: Integer overflow issues with file modes.
14838 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
14840 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
14841 Remove unreachable code.
14842 (read_hex, load_charset_map_from_file): Check for integer overflow.
14844 * xterm.c: Don't go over XClientMessageEvent limit.
14845 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
14846 (x_send_scroll_bar_event): Likewise. Check that the size does not
14847 exceed limits imposed by XClientMessageEvent, as well as the usual
14848 ptrdiff_t and size_t limits.
14850 * keyboard.c: Overflow, signedness and related fixes.
14851 (make_lispy_movement): Use same integer type in forward decl
14852 that is used in the definition.
14853 (read_key_sequence, keyremap_step):
14854 Change bufsize argument back to int, undoing my 2011-03-30 change.
14855 We prefer signed types, and int is wide enough here.
14856 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
14857 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
14858 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
14859 length, not size_t. Use ptrdiff_t for index, not int.
14860 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
14861 possibility of integer overflow.
14863 Overflow, signedness and related fixes for images.
14865 * dispextern.h (struct it.stack[0].u.image.image_id)
14866 (struct_it.image_id, struct image.id, struct image_cache.size)
14867 (struct image_cache.used, struct image_cache.ref_count):

14873 * xdisp.c (calc_pixel_width_or_height):
14874 * xfns.c (image_cache_refcount):
14875 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
14876 on typical 64-bit hosts.

14882 when the callers expect that.
14883 (image_ascent): Redo ascent calculation to avoid int overflow.
14884 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
14885 (lookup_image): Remove unnecessary tests.
14886 (xbm_image_p): Locals are now of int, not EMACS_INT,
14887 since parse_image_check makes sure they fit into int.
14888 (png_load, gif_load, svg_load_image):
14889 Prefer int to unsigned where either will do.
14890 (tiff_handler): New function, combining the cores of the
14891 old tiff_error_handler and tiff_warning_handler.
14892 This function is rewritten to use vsnprintf and thereby avoid
14893 stack buffer overflows. It uses only the features of vsnprintf
14894 that are common to both POSIX and native Microsoft.
14895 (tiff_error_handler, tiff_warning_handler): Use it.
14896 (tiff_load, gif_load, imagemagick_load_image):
14897 Don't assume :index value fits in 'int'.
14898 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
14899 (imagemagick_load_image): Check that crop parameters fit into
14900 the integer types that MagickCropImage accepts. Don't assume
14901 Vimagemagick_render_type has a nonnegative value. Don't assume
14902 size_t fits in 'long'.
14903 (gs_load): Use printmax_t to print the widest integers possible.
14904 Check for integer overflow when computing image height and width.
14906 2011-08-26 Eli Zaretskii <eliz@gnu.org>
14908 * xdisp.c (redisplay_window): Don't force window start if point
14909 will be invisible in the resulting window. (Bug#9324)
14911 2011-08-25 Eli Zaretskii <eliz@gnu.org>
14913 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
14914 the display spec is of the form `(space ...)'.
14915 (handle_display_spec): Return the value returned by
14916 handle_single_display_spec, not just 1 or zero.
14917 (handle_single_display_spec): If the display spec is of the form
14918 `(space ...)', and specifies display in the text area, return 2
14920 (try_cursor_movement): Check for the need to scroll more
14921 accurately, and prefer exact match for point under bidi.
14922 Don't advance `row' beyond the last row of the window.
14924 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
14925 into disp_prop; all users changed.
14927 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
14928 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
14929 for the text covered by the display property.
14931 2011-08-25 Chong Yidong <cyd@stupidchicken.com>
14933 * buffer.c (Fbury_buffer_internal): Rename from Funrecord_buffer.

14935 (Frecord_buffer): Delete unused function.
14937 2011-08-24 Eli Zaretskii <eliz@gnu.org>
14939 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
14940 buffers, return left-to-right.
14941 (set_cursor_from_row): Consider candidate row a win if its glyph
14942 represents a newline and point is on that newline. Fixes cursor
14943 positioning on the newline at EOL of R2L text within L2R
14944 paragraph, and vice versa.
14945 (try_cursor_movement): Check continued rows, in addition to
14946 continuation rows. Fixes unwarranted scroll when point enters a
14947 continued line of R2L text within an L2R paragraph, or vice versa.
14948 (cursor_row_p): Consider the case of point being equal to
14949 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
14950 from the end of a short line to the beginning of a continued line
14951 of R2L text within L2R paragraph.
14952 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
14953 composed characters.
14955 * bidi.c (bidi_check_type): Use xassert.
14956 (bidi_cache_iterator_state): Update the disp_pos and disp_prop_p
14959 2011-08-23 Eli Zaretskii <eliz@gnu.org>
14961 * bidi.c (bidi_get_type): Abort if we get zero as the bidi type of
14964 2011-08-23 Chong Yidong <cyd@stupidchicken.com>
14966 * nsfont.m (ns_otf_to_script): Fix typo.
14968 2011-08-22 Kenichi Handa <handa@m17n.org>
14970 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
14971 extra slot even if the purpose is char-code-property-table.
14973 2011-08-23 Eli Zaretskii <eliz@gnu.org>
14975 * xdisp.c (redisplay_window): When computing centering_position,
14976 account for the height of the header line. (Bug#8874)
14978 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
14979 instead of CHAR_TO_BYTE. Fixes a crash when a completion
14980 candidate is selected by the mouse, and that candidate has a
14981 composed character under the mouse.
14983 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
14984 coordinates reported by pos-visible-in-window-p for a composed
14985 character in column zero.
14987 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
14989 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
14991 2011-08-22 Eli Zaretskii <eliz@gnu.org>
14993 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
14994 consider it a hit if to_charpos is anywhere in the range of the
14995 composed buffer positions.
14997 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
14999 * image.c (gif_load): Don't assume that each subimage has the same
15000 dimensions as the base image. Handle disposal method that is
15001 "undefined" by the gif spec (Bug#9335).
15003 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
15005 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
15006 (Fcondition_case): Document `debug' symbol in error handler.
15008 2011-08-19 Eli Zaretskii <eliz@gnu.org>
15010 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
15011 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
15012 from an Org mode buffer to a Speedbar frame.
15014 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
15015 a composition, take its buffer position from IT->cmp_it.charpos.
15016 Fixes cursor positioning at the beginning of a line that begins
15017 with a composed character.
15019 2011-08-18 Eli Zaretskii <eliz@gnu.org>
15021 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
15022 character bidirectional type, use STRONG_L instead. Fixes crashes
15023 in a buffer produced by `describe-categories'.
15025 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
15026 members before the level stack, so they would be saved and
15027 restored when copying iterator state. Fixes incorrect reordering
15028 around TABs covered by display properties.
15030 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
15032 * process.c (Fnetwork_interface_list): Correctly determine buffer size.
15034 2011-08-17 Chong Yidong <cyd@stupidchicken.com>
15036 * eval.c (internal_condition_case, internal_condition_case_1)
15037 (internal_condition_case_2, internal_condition_case_n):
15038 Remove unnecessary aborts (Bug#9081).
15040 2011-08-17 Eli Zaretskii <eliz@gnu.org>
15042 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
15043 has no `load' handler, try opening the file locally. (Bug#9311)
15045 2011-08-16 Ken Brown <kbrown@cornell.edu>
15047 * gmalloc.c: Expand comment.
15049 2011-08-16 Eli Zaretskii <eliz@gnu.org>
15051 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
15052 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
15054 2011-08-16 Ken Brown <kbrown@cornell.edu>
15056 Fix memory allocation problems in Cygwin build (Bug#9273).
15058 * unexcw.c ( __malloc_initialized): Declare external variable.
15059 (fixup_executable): Force the dumped emacs to reinitialize malloc.
15061 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
15063 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
15065 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
15066 in the static heap.
15067 [CYGWIN] (special_realloc): New function.
15068 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
15069 requests to realloc storage in the static heap.

15082 * dispextern.h: Fix a typo in the comment to bidi_type_t.
15084 * chartab.c: Improve commentary for the uniprop_table API.
15086 * bidi.c (bidi_paragraph_init): Support zero value of
15087 bidi_ignore_explicit_marks_for_paragraph_level.
15088 (bidi_initialize): Use uniprop_table instead of including
15089 biditype.h and bidimirror.h.
15091 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
15092 coordinates of the iterator when restoring from ppos_it.
15095 2011-08-14 Kenichi Handa <handa@m17n.org>
15097 * process.c (create_process): Call setup_process_coding_systems
15098 after the pid of the process is set to -1 (Bug#8162).
15100 2011-08-14 Eli Zaretskii <eliz@gnu.org>
15102 * xdisp.c (move_it_in_display_line_to): Don't invoke
15103 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
15104 ppos_it. Fixes vertical cursor motion when line beginning is
15105 covered by an image. (Bug#9296)
15107 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
15109 * nsterm.h (ns_run_ascript): Declare.
15110 (NSAPP_DATA2_RUNASSCRIPT): Define.
15112 * nsfns.m (as_script, as_result, as_status): New static variables.
15113 (ns_run_ascript): New function.
15114 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
15115 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
15116 the event loop. Get status from as_status (Bug#7276).
15118 * nsterm.m (sendEvent): If event is NSApplicationDefined and
15119 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
15120 the event loop (Bug#7276).
15122 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
15124 * gnutls.c (QCgnutls_bootprop_priority)
15125 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
15126 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
15127 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
15128 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
15129 (QCgnutls_bootprop_verify_hostname_error)
15130 (QCgnutls_bootprop_callbacks_verify): Rename from
15131 Qgnutls_bootprop_..., all uses changed.
15133 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
15136 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
15138 * xfaces.c (Qframe_set_background_mode): Now static.
15139 * dispextern.h (Qframe_set_background_mode): Remove decl.
15141 * process.c (Fnetwork_interface_info): Declare local only if needed.
15143 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
15145 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
15146 (Fnetwork_interface_list): Allocate in increments of bytes instead
15147 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
15148 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
15150 (struct ifflag_def): notrailers is smart on OSX.
15151 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
15152 Get hardware address with getifaddrs if available.
15154 2011-08-12 Eli Zaretskii <eliz@gnu.org>
15156 * xdisp.c (iterate_out_of_display_property): xassert that
15157 IT->position is set to within IT->object's boundaries. Break from
15158 the loop as soon as EOB is reached; avoids infloops in redisplay
15159 when IT->position is set up wrongly due to some bug.
15160 Set IT->current to match the bidi iterator unconditionally.
15161 (push_display_prop): Allow GET_FROM_STRING as IT->method on
15162 entry. Force push_it to save on the stack the current
15163 buffer/string position, to be restored by pop_it. Fix flags in
15164 the iterator structure wrt the object coming from a display
15165 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
15166 properties. (Bug#9284)
15168 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>

15183 no-display-properties-and-no-overlays under bidi display.
15184 Set disp_pos in the bidi iterator to avoid searches for display
15185 properties and overlays.
15187 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
15189 * editfns.c (Fset_time_zone_rule): Document relationship with the

15193 the font entity extracted from the cache (Bug#8109).
15195 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
15197 * composite.c (autocmp_chars): Don't reset point. That is done by
15198 restore_point_unwind (Bug#5984).
15200 2011-08-07 Juri Linkov <juri@jurta.org>
15202 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
15203 to show the arg `TIME' instead of `TIMEVAL'.
15205 2011-08-06 Eli Zaretskii <eliz@gnu.org>
15207 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
15208 display property strides EOL and includes a newline, as in
15209 longlines-mode. (Bug#9254)
15210 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
15211 word-wrap under bidirectional display. (Bug#9224)
15213 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
15214 is non-zero, even if the data buffer is NULL. Fixes a crash in
15215 vertical-motion with longlines-mode. (Bug#9254)
15217 2011-08-05 Eli Zaretskii <eliz@gnu.org>
15219 * bidi.c <bidi_cache_total_alloc>: Now static.
15220 (bidi_initialize): Initialize bidi_cache_total_alloc.
15222 * xdisp.c (display_line): Release buffer allocated for shelved bidi
15225 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
15226 amount allocated this far in `bidi_cache_total_alloc'.
15227 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
15228 non-zero, only free the data buffer without restoring the cache
15229 contents. All callers changed.
15231 * dispextern.h (bidi_unshelve_cache): Update prototype.
15233 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
15234 (move_it_in_display_line, move_it_to)
15235 (move_it_vertically_backward, move_it_by_lines): Replace the call
15236 to xfree to an equivalent call to bidi_unshelve_cache.
15237 (move_it_in_display_line_to): Fix logic of returning
15238 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
15240 2011-08-05 Eli Zaretskii <eliz@gnu.org>
15242 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
15243 came from a string character with a `cursor' property. (Bug#9229)
15245 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
15247 * Makefile.in (LIB_PTHREAD): New variable.
15248 (LIBES): Add LIB_PTHREAD (Bug#9216).
15250 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
15251 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
15253 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
15255 * regex.c (re_iswctype): Remove some redundant boolean conversions.
15257 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
15259 * xterm.c (x_find_topmost_parent): New function.
15260 (x_set_frame_alpha): Find topmost parent window with
15261 x_find_topmost_parent and set the property there also (bug#9181).
15262 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
15264 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
15266 * callproc.c (Fcall_process): Avoid vfork clobbering
15267 the local vars buffer, coding_systems, current_dir.
15269 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
15271 * keymap.c (Fmake_composed_keymap): Move to subr.el.
15273 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
15275 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
15276 so that it is not optimized away.
15278 * xdisp.c (compute_display_string_pos): Remove unused local.
15280 2011-08-02 Eli Zaretskii <eliz@gnu.org>
15282 Fix slow cursor motion and scrolling in large buffers with
15283 selective display, like Org Mode buffers. (Bug#9218)
15285 * dispextern.h (struct bidi_it): New member disp_prop_p.
15287 * xdisp.c: Remove one-slot cache of display string positions.
15288 (compute_display_string_pos): Accept an additional argument
15289 DISP_PROP_P; callers changed. Scan at most 5K characters forward
15290 for a display string or property. If found, set DISP_PROP_P
15293 * bidi.c (bidi_fetch_char): Accept an additional argument
15294 DISP_PROP_P, and pass it to compute_display_string_pos.
15295 Only handle text covered by a display string if DISP_PROP_P is returned
15296 non-zero. All callers of bidi_fetch_char changed.
15298 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
15300 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
15302 2010-12-03 Don March <don@ohspite.net>
15304 * keymap.c (Fdefine_key): Fix non-prefix key error message when
15305 last character M-[char] is translated to ESC [char] (bug#7541).
15307 2011-08-02 Kenichi Handa <handa@m17n.org>
15309 * lisp.h (uniprop_table): Extern it.
15311 * chartab.c (uniprop_table): Make it non-static.
15313 2011-08-01 Eli Zaretskii <eliz@gnu.org>
15315 * xdisp.c (forward_to_next_line_start): Accept additional argument
15316 BIDI_IT_PREV, and store into it the state of the bidi iterator had
15318 (reseat_at_next_visible_line_start): Use the bidi iterator state
15319 returned by forward_to_next_line_start to restore the state of
15320 it->bidi_it after backing up to previous newline. (Bug#9212)
15322 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
15324 * regex.c (re_comp): Protoize.
15325 (re_exec): Fix return type.
15326 (regexec): Fix type of `ret'. (Bug#9203)
15328 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15330 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
15331 This is needed if max-image-size is a floating-point number.
15333 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15335 * print.c (print_object): Print empty symbol as ##.
15337 * lread.c (read1): Read ## as empty symbol.
15339 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
15341 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
15342 setting frame foreground color (Bug#9175).
15343 (x_set_background_color): Likewise.
15345 * nsmenu.m (-setText): Size tooltip dimensions precisely to
15346 contents (Bug#9176).
15347 (EmacsTooltip -init): Remove bezels and add shadows to
15350 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
15351 or scroll bar (Bug#8470).
15353 * nsfont.m (nsfont_open): Remove assignment to voffset and
15354 unnecessary vars hshink, expand, hd, full_height, min_height.
15355 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
15357 * nsterm.h (nsfont_info): Remove voffset field.
15359 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
15361 Implement strike-through and overline on NextStep (Bug#8863).
15363 * nsfont.m (nsfont_open): Use underline position provided by font,
15364 instead of hard-coded value of 2.
15365 (nsfont_draw): Call ns_draw_text_decoration instead.
15367 * nsterm.h: Add declaration for ns_draw_text_decoration.
15369 * nsterm.m (ns_draw_text_decoration): New function for drawing
15370 underline, overline, and strike-through.
15371 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
15372 ns_draw_text_decoration. Change treatment of cursor drawing to
15373 accommodate underlining, etc.
15375 2011-07-28 Eli Zaretskii <eliz@gnu.org>
15377 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
15380 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15382 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
15383 Without this fix, if a signal arrives just after memory fills up,
15384 'malloc' might be invoked reentrantly.
15386 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
15387 In other words, assume that every image size is allowed, on non-X
15388 hosts. This assumption is probably wrong, but it lets Emacs compile.
15390 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15392 * regex.c (re_iswctype): Convert return values to boolean.
15394 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
15396 * xdisp.c (compute_display_string_pos): Don't use cached display
15397 string position if the buffer had its restriction changed.
15400 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15402 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
15404 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15406 Integer signedness and overflow and related fixes. (Bug#9079)
15408 * bidi.c: Integer size and overflow fixes.
15409 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
15410 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
15411 (bidi_cache_find_level_change, bidi_cache_ensure_space)
15412 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
15413 (bidi_find_other_level_edge):
15414 Use ptrdiff_t instead of EMACS_INT where either will do.
15415 This works better on 32-bit hosts configured --with-wide-int.
15416 (bidi_cache_ensure_space): Check for size-calculation overflow.
15417 Use % rather than repeated addition, for better worst-case speed.
15418 Don't set bidi_cache_size until after xrealloc returns, because it
15420 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
15421 (bidi_cache_ensure_space): Also check that the bidi cache size
15422 does not exceed that of the largest Lisp string or buffer. See Eli
15423 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
15425 * alloc.c (__malloc_size_t): Remove.
15426 All uses replaced by size_t. See Andreas Schwab's note
15427 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
15429 * image.c: Improve checking for integer overflow.
15430 (check_image_size): Assume that f is nonnull, since
15431 it is always nonnull in practice. This is one less thing to
15432 worry about when checking for integer overflow later.
15433 (x_check_image_size): New function, which checks for integer
15434 overflow issues inside X.
15435 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
15436 This removes the need for a memory_full check.
15437 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
15438 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
15439 (xbm_read_bitmap_data): Change locals back to 'int', since
15440 their values must fit in 'int'.
15441 (xpm_load_image, png_load, tiff_load):
15442 Invoke x_create_x_image_and_pixmap earlier,
15443 to avoid much needless work if the image is too large.
15444 (tiff_load): Treat overly large images as if
15445 x_create_x_image_and_pixmap failed, not as malloc failures.
15446 (gs_load): Use x_check_image_size.
15448 * gtkutil.c: Omit integer casts.
15449 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
15450 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
15452 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
15454 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
15455 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
15456 would wrongly return t on a 64-bit host.
15458 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
15459 The plain *_OVERFLOW macros run afoul of GCC bug 49705
15460 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
15461 and therefore cause GCC to emit a bogus diagnostic in some cases.
15463 * image.c: Integer signedness and overflow and related fixes.
15464 This is not an exhaustive set of fixes, but it's time to
15465 record what I've got.
15466 (lookup_pixel_color, check_image_size): Remove redundant decls.
15467 (check_image_size): Don't assume that arbitrary EMACS_INT values
15468 fit in 'int', or that arbitrary 'double' values fit in 'int'.
15469 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
15470 (tiff_load, imagemagick_load_image):
15471 Check for overflow in size calculations.
15472 (x_create_x_image_and_pixmap): Remove unnecessary test for
15473 xmalloc returning NULL; that can't happen.
15474 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
15475 (xpm_color_bucket): Use better integer hashing function.
15476 (xpm_cache_color): Don't possibly over-allocate memory.
15477 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
15478 (gif_memory_source):
15479 Use ptrdiff_t, not int or size_t, to record sizes.
15480 (png_load): Don't assume values greater than 2**31 fit in 'int'.
15481 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
15482 either works, as we prefer signed integers.
15483 (tiff_read_from_memory, tiff_write_from_memory):
15484 Return tsize_t, not size_t, since that's what the TIFF API wants.
15485 (tiff_read_from_memory): Don't fail simply because the read would
15486 go past EOF; instead, return a short read.
15487 (tiff_load): Omit no-longer-needed casts.
15488 (Fimagemagick_types): Don't assume size fits into 'int'.
15490 Improve hashing quality when configured --with-wide-int.
15491 * fns.c (hash_string): New function, taken from sxhash_string.
15492 Do not discard information about ASCII character case; this
15493 discarding is no longer needed.
15494 (sxhash-string): Use it. Change sig to match it. Caller changed.
15495 * lisp.h: Declare it.
15496 * lread.c (hash_string): Remove, since we now use fns.c's version.
15497 The fns.c version returns a wider integer if --with-wide-int is
15498 specified, so this should help the quality of the hashing a bit.
15500 * emacs.c: Integer overflow minor fix.
15501 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
15502 Define only if GNU_LINUX.
15503 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
15505 * dispnew.c: Integer signedness and overflow fixes.
15506 Remove unnecessary forward decls, that were a maintenance hassle.
15507 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
15509 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
15510 (scrolling_window): Use ptrdiff_t, not int, for byte count.
15511 (prepare_desired_row, line_draw_cost):
15512 Use int, not unsigned, where either works.
15513 (save_current_matrix, restore_current_matrix):
15514 Use ptrdiff_t, not size_t, where either works.
15515 (init_display): Check for overflow more accurately, and without
15516 relying on undefined behavior.
15518 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
15519 Remove, replacing with the new symbols in lisp.h. All uses changed.
15520 * fileio.c (make_temp_name):
15521 * filelock.c (lock_file_1, lock_file):
15522 * xdisp.c (message_dolog):
15523 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
15524 Use pMd etc. instead.
15525 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
15526 replacing the pWIDE etc. symbols removed from editfns.c.
15528 * keyboard.h (num_input_events): Now uintmax_t.
15529 This is (very slightly) less likely to mess up due to wraparound.
15532 * buffer.c: Integer signedness fixes.
15533 (alloc_buffer_text, enlarge_buffer_text):
15534 Use ptrdiff_t rather than size_t when either will do, as we prefer
15537 * alloc.c: Integer signedness and overflow fixes.
15538 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
15539 (__malloc_size_t): Default to size_t, not to int.
15540 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
15541 (Fgarbage_collect, mark_object_loop_halt, mark_object):
15542 Prefer ptrdiff_t to size_t when either would do, as we prefer
15544 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
15545 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
15546 Now const. Initialize with values that are in range even if char
15548 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
15549 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
15550 These functions do the right thing with sizes > 2**32.
15551 (check_depth): Now ptrdiff_t, not int.
15552 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
15553 Adjust to new way of storing sizes. Check for size overflow bugs
15555 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
15556 slightly wrong anyway, as it missed one instance of
15557 XMALLOC_OVERRUN_CHECK_OVERHEAD.
15558 (refill_memory_reserve): Omit needless cast to size_t.
15559 (mark_object_loop_halt): Mark as externally visible.
15561 * xselect.c: Integer signedness and overflow fixes.
15562 (Fx_register_dnd_atom, x_handle_dnd_message):
15563 Use ptrdiff_t, not size_t, since we prefer signed.
15564 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
15565 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
15566 x_dnd_atoms_size and x_dnd_atoms_length.
15568 * doprnt.c: Prefer signed to unsigned when either works.
15570 * doprnt.c (doprnt):
15572 * xdisp.c (vmessage):
15573 Use ptrdiff_t, not size_t, when using or implementing doprnt,
15574 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
15575 prefer signed arithmetic to avoid comparison confusion.
15576 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
15577 but is a bit tricky.
15579 Assume freestanding C89 headers, string.h, stdlib.h.
15580 * data.c, doprnt.c, floatfns.c, print.c:
15581 Include float.h unconditionally.
15582 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
15583 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
15584 * regex.c: Likewise for stddef.h, string.h.
15585 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
15586 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
15587 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
15588 (STDC_HEADERS): Remove obsolete defines.
15589 * sysdep.c: Include limits.h unconditionally.
15591 Assume support for memcmp, memcpy, memmove, memset.
15592 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
15593 * regex.c (memcmp, memcpy):
15594 Remove; we assume C89 now.
15596 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
15597 (__malloc_safe_bcopy): Remove; no longer needed.
15599 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
15600 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
15601 well either way, and we prefer signed to unsigned.
15603 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
15605 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
15606 closes the connection while we're reading (bug#9182).
15608 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
15610 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
15611 are specified (Bug#9168).
15613 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
15615 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
15616 Found by GCC static checking and --with-wide-int on a 32-bit host.
15618 2011-07-25 Eli Zaretskii <eliz@gnu.org>
15620 * xdisp.c (compute_display_string_pos): Fix logic of caching
15621 previous display string position. Initialize cached_prev_pos to
15622 -1. Fixes slow-down at the beginning of a buffer.
15624 2011-07-24 Eli Zaretskii <eliz@gnu.org>
15626 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
15627 for attrs[LFACE_FONTSET_INDEX].
15629 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
15631 * xml.c (parse_region): Remove unused local
15632 that was recently introduced.
15634 2011-07-23 Eli Zaretskii <eliz@gnu.org>
15636 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
15637 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
15639 * xdisp.c (move_it_in_display_line_to): Record the best matching
15640 position for TO_CHARPOS while scanning the line, and restore it on
15641 exit if none of the characters scanned was an exact match.
15642 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
15643 when exact match is impossible due to invisible text, and the
15644 lines are truncated.
15646 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
15648 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
15651 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15653 Fix a significant slow-down of cursor motion with C-n, C-p,
15654 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
15655 auto-repeat under bidi redisplay in fontified buffers.
15656 * xdisp.c (compute_stop_pos_backwards): New function.
15657 (next_element_from_buffer): Call compute_stop_pos_backwards to
15658 find a suitable prev_stop when we find ourselves before
15660 (reseat): Don't look for prev_stop, as that could mean a very long
15662 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
15663 <cached_disp_overlay_modiff>: Cache for last found display string
15665 (compute_display_string_pos): Return the cached position if asked
15666 about the same buffer in the same area of character positions, and
15667 the buffer wasn't changed since the time the display string
15668 position was cached.
15670 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15672 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
15673 is an integer, which is important for empty lines. (Bug#9149)
15675 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
15677 * frame.c (Fmodify_frame_parameters): In tty case, update the
15678 default face if necessary (Bug#4238).
15680 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
15682 * editfns.c (Fstring_to_char): No need to explain what a character
15683 is in the docstring (Bug#6576).
15685 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15687 * xml.c (parse_region): Make sure we always return a tree.
15689 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
15691 * xml.c (parse_region): If a document contains only comments,
15694 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15696 * xml.c (make_dom): Return comments, too.
15698 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
15701 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
15702 and the surrounding thread.
15703 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
15704 rather than fgets, and retry after EINTR. Otherwise, 'emacs
15705 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
15707 * s/openbsd.h (BROKEN_SIGIO): Define.
15708 * unexelf.c (unexec) [__OpenBSD__]:
15709 Don't update the .mdebug section of the Alpha COFF symbol table.
15711 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15713 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
15716 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
15718 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
15719 This fixes some race conditions on the permissions of any newly
15722 * alloc.c (valid_pointer_p): Use pipe, not open.
15723 This fixes some permissions issues when debugging.
15725 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
15726 If fchown fails to set both uid and gid, try to set just gid,
15727 as that is sometimes allowed. Adjust the file's mode to eliminate
15728 setuid or setgid bits that are inappropriate if fchown fails.
15730 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
15732 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ

15738 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
15740 * lread.c (read_integer): Unread even EOF character.
15741 (read1): Likewise. Properly record start position of symbol.

15744 symbol character follows.
15746 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
15748 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
15749 This works around a problem with the previous change to Fcopy_file.
15750 Recent glibc declares fchown with __attribute__((warn_unused_result)),
15751 and without this change, GCC might complain about discarding
15752 fchown's return value.
15754 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
15756 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
15758 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
15760 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
15762 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
15764 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
15765 it's used from the C level.
15767 * process.c: Use the same condition for POLL_FOR_INPUT in both
15768 keyboard.c and process.c (bug#1858).
15770 2011-07-09 Lawrence Mitchell <wence@gmx.li>
15772 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
15773 (Fgnutls_boot): Use it.
15775 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
15777 * doc.c (Fsubstitute_command_keys): Revert last change.
15779 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
15781 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
15782 quotes the next character, and doesn't affect other longer
15783 sequences (bug#8935).
15785 * lread.c (syms_of_lread): Clarify that is isn't only
15786 `eval-buffer' and `eval-defun' that's affected by
15787 `lexical-binding' (bug#8460).
15789 2011-07-15 Eli Zaretskii <eliz@gnu.org>
15791 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
15792 bidi redisplay when a line includes both an image and is truncated.
15794 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
15796 Fix minor problems found by static checking.
15797 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
15798 (elsz): Now a signed constant, not a size_t var. We prefer signed
15799 types to unsigned, to avoid integer comparison confusion. Without
15800 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
15801 "cannot optimize loop, the loop counter may overflow", a symptom
15803 * indent.c (Fvertical_motion): Mark locals as initialized.
15804 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
15806 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>

15829 buffer position was specified. Initialize paragraph_embedding to
15831 (reseat_to_string): Initialize the bidi iterator.
15832 (display_string): If we need to ignore text properties of
15833 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
15834 original value of -1 will not work with bidi.)
15835 (compute_display_string_pos): First arg is now struct
15836 `text_pos *'; all callers changed. Support display properties on
15838 (compute_display_string_end): Support display properties on Lisp
15840 (init_iterator, reseat_1, reseat_to_string): Initialize the
15841 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
15842 when iterating on a string not from display properties).
15843 (compute_display_string_pos, compute_display_string_end):
15844 Fix calculation of the object to scan. Fixes an error when using
15846 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
15847 base_level_stop; instead, set base_level_stop to BEGV.
15848 Fixes crashes in vertical-motion.
15849 (next_element_from_buffer): Improve commentary for when
15850 the iterator is before prev_stop.
15851 (init_iterator): Initialize bidi_p from the default value of
15852 bidi-display-reordering, not from buffer-local value. Use the
15853 buffer-local value only if initializing for buffer iteration.

15874 parts of next_element_from_buffer, next_element_from_string, and
15875 next_element_from_c_string.

15877 (display_menu_bar): Force left-to-right direction. Add a FIXME
15878 comment for making that be controlled by a user option.

15887 (get_overlay_strings_1, push_display_prop): Set up the bidi
15888 iterator for displaying display or overlay strings.
15889 (forward_to_next_line_start): Don't use the shortcut if
15891 (back_to_previous_visible_line_start): If handle_display_prop
15892 pushed the iterator stack, restore the internal state of the bidi
15893 iterator by calling bidi_pop_it same number of times.
15894 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
15895 and we are bidi-iterating, don't decrement the iterator position;
15896 instead, set the first_elt flag in the bidi iterator, to produce
15898 (reseat_1): Remove redundant setting of string_from_display_prop_p.
15899 (push_display_prop): xassert that we are iterating a buffer.
15900 (push_it, pop_it): Save and restore paragraph_embedding member.
15901 (handle_single_display_spec, next_overlay_string)
15902 (get_overlay_strings_1, reseat_1, reseat_to_string)
15903 (push_display_prop): Set up the `unibyte' member of bidi_it.string
15904 correctly. Don't assume unibyte strings are not bidi-reordered.

15913 property. Fix a typo in popping stretch info. Add an assertion
15914 for verifying that the iterator position is in sync with the bidi
15916 (handle_single_display_spec, get_overlay_strings_1)

15941 displayed in margins. (Bug#8133) (Bug#8867)
15942 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past

15970 changed to -1 and -2, respectively.
15971 (bidi_char_at_pos): New function.
15972 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):

16056 Vx_lost_selection_functions to Frun_hook_with_args.
16058 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
16060 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
16061 The old code sometimes used this field without initializing it.
16063 * alloc.c (gc_sweep): Don't read past end of array.
16064 In theory, the old code could also have corrupted Emacs internals,
16065 though it'd be very unlikely.

16331 if Emacs is configured with --with-wide-int.
16332 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):

16370 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
16371 subseconds part to the entropy, as that's a bit more random.
16372 Prefer signed to unsigned, since the signedness doesn't matter and
16373 in general we prefer signed. When given a limit, use a
16374 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
16375 latter isn't right if USE_2_TAGS_FOR_INTS.
16376 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
16377 not 0..VALMASK. Don't discard "excess" bits that random () returns.

16389 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
16390 This is more efficient than Ffile_directory_p and avoids a minor race.

16394 * buffer.c (Foverlay_put): Say what the return value is
16397 * fileio.c (barf_or_query_if_file_exists): Check first if the file
16398 is a directory before asking whether to use the file name

16401 error be more correct.
16403 * fns.c (Frequire): Remove the mention of the .gz files, since

16417 Qgnutls_bootprop_verify_error (which is no longer used).
16419 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
16420 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
16421 Also (re)move comments that are misplaced or no longer relevant.

16450 * lread.c (syms_of_lread): Mention single symbols defined by

16499 * xsettings.c (store_monospaced_changed): Take new font as arg and
16500 check for change against current_mono_font.

16504 (emacs_settings_init, gsettings_obj): Remove.
16505 (something_changedCB): New function for HAVE_GSETTINGS.

16507 with value as argument.
16508 (init_gsettings): Check that GSETTINGS_SCHEMA exists before calling
16509 g_settings_new (Bug#8967). Do not create gsettings_obj.

16522 * eval.c (struct backtrace): Simplify and port the data structure.
16523 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
16524 signed bit field, as this assumption is not portable and it makes
16525 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
16526 "char debug_on_exit : 1" as this is not portable either; instead,
16527 use the portable "unsigned int debug_on_exit : 1". Remove unused
16528 member evalargs. Remove obsolete comments about cc bombing out.
16530 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

16571 (sort_overlays, overlay_strings): When an overlay's clone number
16572 matches the window's clone number process the overlay even if
16573 the overlay's window property doesn't match the current window.
16575 * window.c (Fwindow_vchild): Rename to Fwindow_top_child.

16598 (emacs_fixed_new): Set priv->f to argument.
16599 (emacs_fixed_get_preferred_width)
16600 (emacs_fixed_get_preferred_height): Use min_width/height from
16601 frames size_hint to set minimum and natural (Bug#8919).
16602 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
16603 and use min_width/height from frames size_hint to set
16604 min_width/height (Bug#8919).
16606 * gtkutil.c (xg_create_frame_widgets): Pass f to emacs_fixed_new.

16624 Use gnulib's dup2 module instead of rolling our own.
16625 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.

16692 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
16694 Integer and buffer overflow fixes (Bug#8873).
16696 * print.c (printchar, strout): Check for string overflow.
16697 (PRINTPREPARE, printchar, strout):
16698 Don't set size unless allocation succeeds.
16700 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
16701 for sizes. Check for string overflow more accurately.
16702 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
16704 * macros.c: Integer and buffer overflow fixes.
16705 * keyboard.h (struct keyboard.kbd_macro_bufsize):
16706 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

16710 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
16712 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
16714 * lread.c: Integer overflow fixes.
16715 (read_integer): Radix is now EMACS_INT, not int,
16716 to improve quality of diagnostics for out-of-range radices.
16717 Calculate buffer size correctly for out-of-range radices.
16718 (read1): Check for integer overflow in radices, and in
16719 read-circle numbers.
16720 (read_escape): Avoid int overflow.
16721 (Fload, openp, read_buffer_size, read1)
16722 (substitute_object_recurse, read_vector, read_list, map_obarray):
16723 Use ptrdiff_t, not int, for sizes.

16738 2011-06-22 Leo Liu <sdl.web@gmail.com>
16740 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
16741 Move to minibuffer.el.
16743 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
16745 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
16746 The following patches are for when GLYPH_DEBUG && !XASSERT.
16747 * dispextern.h (trace_redisplay_p, dump_glyph_string):
16748 * dispnew.c (flush_stdout):
16749 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
16750 Mark as externally visible.
16751 * dispnew.c (check_window_matrix_pointers): Now static.
16752 * dispnew.c (window_to_frame_vpos):
16753 * xfns.c (unwind_create_frame):
16754 * xterm.c (x_check_font): Remove unused local.
16755 * scroll.c (CHECK_BOUNDS):
16756 * xfaces.c (cache_fache): Rename local to avoid shadowing.
16757 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
16758 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
16759 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
16760 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
16762 (debug_method_add): Use va_list and vsprintf rather than relying
16763 on undefined behavior with wrong number of arguments.
16764 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
16765 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
16766 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
16767 since we're not interested in debugging glyphs with old libraries.
16768 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
16769 GCC 4.6.0's static checking.
16771 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
16773 Integer overflow and signedness fixes (Bug#8873).
16774 A few related buffer overrun fixes, too.

16783 (x_create_bitmap_from_xpm_data):
16784 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
16785 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
16787 * xfaces.c (load_pixmap):
16788 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
16789 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
16790 (.bitmaps_last, struct x_output.icon_bitmap):
16791 Use ptrdiff_t, not int, for bitmap indexes.
16792 (x_allocate_bitmap_record): Check for size overflow.
16793 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
16795 Use ptrdiff_t, not int, for overlay counts.
16796 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
16797 * editfns.c (overlays_around, get_pos_property):
16798 * textprop.c (get_char_property_and_overlay):
16799 * xdisp.c (next_overlay_change, note_mouse_highlight):
16800 * xfaces.c (face_at_buffer_position):
16801 * buffer.c (OVERLAY_COUNT_MAX): New macro.
16802 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
16803 (Fnext_overlay_change, Fprevious_overlay_change)
16804 (mouse_face_overlay_overlaps, Foverlays_in):
16805 Use ptrdiff_t, not int, for sizes.
16806 (overlays_at, overlays_in): Check for size-calculation overflow.
16808 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
16810 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
16811 (x_session_initialize): Do not assume string length fits in int.
16813 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
16814 This is unlikely, but can occur if DPI is outlandish.
16816 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
16817 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
16819 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
16820 * xrdb.c (magic_file_p, search_magic_path):
16821 Omit last arg SUFFIX; it was always 0. All callers changed.
16822 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
16824 * xfont.c (xfont_match): Avoid need for strlen.
16826 * xfns.c: Don't assume strlen fits in int.

16829 * xdisp.c (message_log_check_duplicate): Return intmax_t,
16830 not unsigned long, as we prefer signed integers. All callers changed.
16831 Detect integer overflow in repeat count.
16832 (message_dolog): Don't assume print length fits in 39 bytes.
16833 (display_mode_element): Don't assume strlen fits in int.
16835 * termcap.c: Don't assume sizes fit in int and never overflow.
16836 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
16837 (gobble_line): Check for size-calculation overflow.
16839 * minibuf.c (Fread_buffer):
16840 * lread.c (intern, intern_c_string):
16841 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
16842 Don't assume string length fits in int.

16854 * filelock.c: Fix some buffer overrun and integer overflow issues.
16855 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
16856 Reformulate so as not to need the command string.
16857 Invoke gzip -cd rather than gunzip, as it's more portable.
16858 (lock_info_type, lock_file_1, lock_file):
16859 Don't assume pid_t and time_t fit in unsigned long.
16860 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
16861 (current_lock_owner): Prefer signed type for sizes.
16862 Use memcpy, not strncpy, where memcpy is what is really wanted.
16863 Don't assume (via atoi) that time_t and pid_t fit in int.
16864 Check for time_t and/or pid_t out of range, e.g., via a network share.
16865 Don't alloca where an auto var works fine.
16867 * fileio.c: Fix some integer overflow issues.
16868 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
16869 Don't assume string length fits in int.
16870 (directory_file_name): Don't assume string length fits in long.
16871 (make_temp_name): Don't assume pid fits in int, or that its print
16872 length is less than 20.
16874 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
16876 * coding.c (make_subsidiaries): Don't assume string length fits in int.
16878 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
16880 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.

16883 * emacs.c: Don't assume string length fits in 'int'.
16884 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
16885 (main): Don't invoke strlen when not needed.
16887 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.

16890 * callproc.c (getenv_internal_1, getenv_internal)
16891 (Fgetenv_internal):
16892 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
16894 * lread.c (invalid_syntax): Omit length argument.
16895 All uses changed. This doesn't fix a bug, but it simplifies the
16896 code away from its former Hollerith-constant appearance, and it's
16897 one less 'int' to worry about when looking at integer-overflow issues.
16898 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
16900 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
16901 This didn't break anything, but it didn't help either.
16902 It's confusing to put a bogus integer in a place where the actual
16903 value does not matter.
16904 (LIST_END_P): Remove unused macro and its bogus comment.
16905 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
16907 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
16908 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
16910 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
16911 We prefer signed types, and the value cannot exceed the EMACS_INT
16912 range anyway (because otherwise the length would not be representable).
16913 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
16914 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
16915 This avoids a GCC warning when WIDE_EMACS_INT.
16917 * indent.c (sane_tab_width): New function.
16918 (current_column, scan_for_column, Findent_to, position_indentation)
16919 (compute_motion): Use it. This is just for clarity.
16920 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
16922 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
16924 * lisp.h (lint_assume): New macro.
16925 * composite.c (composition_gstring_put_cache):
16926 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
16928 * editfns.c, insdel.c:
16929 Omit unnecessary forward decls, to simplify future changes.
16931 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
16933 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
16935 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
16936 Use much-faster test for byte-length change.
16937 Don't assume string byte-length fits in 'int'.
16938 Check that character arg fits in 'int'.
16939 (mapcar1): Declare byte as byte, for clarity.
16941 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
16943 * fns.c (concat): Catch string overflow earlier.
16944 Do not rely on integer wraparound.
16946 * dispextern.h (struct it.overlay_strings_charpos)
16947 (struct it.selective): Now EMACS_INT, not int.
16948 * xdisp.c (forward_to_next_line_start)
16949 (back_to_previous_visible_line_start)
16950 (reseat_at_next_visible_line_start, next_element_from_buffer):
16951 Don't arbitrarily truncate the value of 'selective' to int.
16953 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
16955 * composite.c: Don't truncate sizes to 'int'.
16956 (composition_gstring_p, composition_reseat_it)
16957 (composition_adjust_point): Use EMACS_INT, not int.
16958 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
16959 not EMACS_UINT, for indexes.
16961 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
16963 * buffer.c: Include <verify.h>.
16964 (struct sortvec.priority, struct sortstr.priority):
16965 Now EMACS_INT, not int.
16966 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
16967 (struct sortstr.size, record_overlay_string)
16968 (struct sortstrlist.size, struct sortlist.used):
16969 Don't truncate size to int.
16970 (record_overlay_string): Check for size-calculation overflow.
16971 (init_buffer_once): Check at compile-time, not run-time.
16973 2011-06-22 Jim Meyering <meyering@redhat.com>
16975 Don't leak an XBM-image-sized buffer
16976 * image.c (xbm_load): Free the image buffer after using it.
16978 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
16981 * composite.c (find_automatic_composition): Omit needless 'return 0;'
16982 that Sun C diagnosed.
16983 * fns.c (secure_hash): Fix pointer signedness issue.
16984 * intervals.c (static_offset_intervals): New function.
16985 (offset_intervals): Use it.
16987 2011-06-21 Leo Liu <sdl.web@gmail.com>
16990 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
16993 * fns.c (secure_hash): Rename from crypto_hash_function and change
16994 the first arg to accept symbols.
16995 (Fsecure_hash): New primitive.
16996 (syms_of_fns): New symbols.
16998 2011-06-20 Deniz Dogan <deniz@dogan.se>
17000 * process.c (Fset_process_buffer): Clarify return value in
17003 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
17005 * dispnew.c (add_window_display_history): Use BVAR.
17007 * xdisp.c (debug_method_add): Use BVAR.
17008 (check_window_end, dump_glyph_matrix, dump_glyph)
17009 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
17011 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
17014 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
17015 check till after the cache is created in init_frame_faces.
17017 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
17019 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
17021 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
17023 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
17024 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
17025 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
17027 Improve buffer-overflow checking (Bug#8873).
17028 * fileio.c (Finsert_file_contents):
17029 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
17030 Remove the old (too-loose) buffer overflow checks.
17031 They weren't needed, since make_gap checks for buffer overflow.
17032 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
17033 The old code merely checked for Emacs fixnum overflow, and relied
17034 on undefined (wraparound) behavior. The new code avoids undefined
17035 behavior, and also checks for ptrdiff_t and/or size_t overflow.
17037 * editfns.c (Finsert_char): Don't dump core with very negative counts.
17038 Tune. Don't use wider integers than needed. Don't use alloca.
17039 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
17041 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
17043 * insdel.c, lisp.h (buffer_overflow): New function.
17044 (insert_from_buffer_1, replace_range, replace_range_2):
17045 * insdel.c (make_gap_larger):
17046 * editfns.c (Finsert_char):
17047 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
17049 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
17051 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
17053 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
17055 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
17056 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
17058 * fileio.c: Don't assume EMACS_INT fits in off_t.
17059 (emacs_lseek): New static function.
17060 (Finsert_file_contents, Fwrite_region): Use it.
17061 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
17063 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
17065 * fns.c: Don't overflow int when computing a list length.
17066 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
17067 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
17068 truncation on 64-bit hosts. Check for QUIT every
17069 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
17070 faster and is responsive enough.
17071 (Flength): Report an error instead of overflowing an integer.
17072 (Fsafe_length): Return a float if the value is not representable
17073 as a fixnum. This shouldn't happen except in contrived situations.
17074 (Fnthcdr, Fsort): Don't assume list length fits in int.
17075 (Fcopy_sequence): Don't assume vector length fits in int.
17077 * alloc.c: Check that resized vectors' lengths fit in fixnums.
17078 (header_size, word_size): New constants.
17079 (allocate_vectorlike): Don't check size overflow here.
17080 (allocate_vector): Check it here instead, since this is the only
17081 caller of allocate_vectorlike that could cause overflow.
17082 Check that the new vector's length is representable as a fixnum.
17084 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
17085 The previous code was bogus. For example, next_almost_prime (32)
17086 returned 39, which is undesirable as it is a multiple of 3; and
17087 next_almost_prime (24) returned 25, which is a multiple of 5 so
17088 why was the code bothering to check for multiples of 7?
17090 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
17092 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
17094 Variadic C functions now count arguments with ptrdiff_t.
17095 This partly undoes my 2011-03-30 change, which replaced int with size_t.
17096 Back then I didn't know that the Emacs coding style prefers signed int.
17097 Also, in the meantime I found a few more instances where arguments
17098 were being counted with int, which may truncate counts on 64-bit
17099 machines, or EMACS_INT, which may be unnecessarily wide.
17100 * lisp.h (struct Lisp_Subr.function.aMANY)
17101 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
17102 Arg counts are now ptrdiff_t, not size_t.
17103 All variadic functions and their callers changed accordingly.
17104 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
17105 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
17106 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
17107 * callint.c (Fcall_interactively): Check arg count for overflow,
17108 to avoid potential buffer overrun. Use signed char, not 'int',
17109 for 'varies' array, so that we needn't bother to check its size
17110 calculation for overflow.
17111 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
17112 * eval.c (apply_lambda):
17113 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
17114 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
17115 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
17117 * callint.c (Fcall_interactively): Don't use index var as event count.
17119 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
17120 * mem-limits.h (SIZE): Remove; no longer used.
17122 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
17124 Remove unnecessary casts.
17125 * xterm.c (x_term_init):
17126 * xfns.c (x_set_border_pixel):
17127 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
17128 These aren't needed now that we assume ANSI C.
17130 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
17131 It's more likely to cause problems (due to unsigned overflow)
17134 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
17136 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
17138 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
17140 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
17142 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
17144 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
17146 GLYPH_CODE_FACE returns EMACS_INT, not int.
17147 * dispextern.h (merge_faces):
17148 * xfaces.c (merge_faces):
17149 * xdisp.c (get_next_display_element, next_element_from_display_vector):
17150 Don't assume EMACS_INT fits in int.
17152 * character.h (CHAR_VALID_P): Remove unused parameter.
17153 * fontset.c, lisp.h, xdisp.c: All uses changed.
17155 * editfns.c (Ftranslate_region_internal): Omit redundant test.
17157 * fns.c (concat): Minor tuning based on overflow analysis.
17158 This doesn't fix any bugs. Use int to hold character, instead
17159 of constantly refetching from Emacs object. Use XFASTINT, not
17160 XINT, for value known to be a character. Don't bother comparing
17161 a single byte to 0400, as it's always less.
17163 * floatfns.c (Fexpt):
17164 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
17166 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
17169 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
17171 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
17172 Without this fix, on a 64-bit host (aset S 0 4294967386) would
17173 incorrectly succeed when S was a string, because 4294967386 was
17174 truncated before it was used.
17176 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
17177 Otherwise, an out-of-range integer could cause undefined behavior
17180 * composite.c: Use int, not EMACS_INT, for characters.
17181 (fill_gstring_body, composition_compute_stop_pos): Use int, not
17182 EMACS_INT, for values that are known to be in character range.
17183 This doesn't fix any bugs but is the usual style inside Emacs and
17184 may generate better code on 32-bit machines.
17186 Make sure a 64-bit char is never passed to ENCODE_CHAR.
17187 This is for reasons similar to the recent CHAR_STRING fix.
17188 * charset.c (Fencode_char): Check that character arg is actually
17189 a character. Pass an int to ENCODE_CHAR.
17190 * charset.h (ENCODE_CHAR): Verify that the character argument is no
17191 wider than 'int', as a compile-time check to prevent future regressions
17194 * character.c (char_string): Remove unnecessary casts.
17196 Make sure a 64-bit char is never passed to CHAR_STRING.
17197 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
17198 by silently ignoring the top 32 bits, allowing some values
17199 that were far too large to be valid characters.
17200 * character.h: Include <verify.h>.
17201 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
17202 arguments are no wider than unsigned, as a compile-time check
17203 to prevent future regressions in this area.
17205 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
17206 (Fsubst_char_in_region):
17208 * xdisp.c (decode_mode_spec_coding):
17209 Adjust to CHAR_STRING's new requirement.
17210 * editfns.c (Finsert_char, Fsubst_char_in_region):
17211 * fns.c (concat): Check that character args are actually
17212 characters. Without this test, these functions did the wrong
17213 thing with wildly out-of-range values on 64-bit hosts.
17215 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
17216 These casts should not be needed on 32-bit hosts, either.
17217 * keyboard.c (read_char):
17218 * lread.c (Fload): Remove casts to unsigned.
17220 * lisp.h (UNSIGNED_CMP): New macro.
17221 This fixes comparison bugs on 64-bit hosts.
17222 (ASCII_CHAR_P): Use it.
17223 * casefiddle.c (casify_object):
17224 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
17225 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
17226 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
17227 * dispextern.h (FACE_FROM_ID):
17228 * keyboard.c (read_char): Use UNSIGNED_CMP.
17230 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
17231 not to EMACS_INT, to avoid GCC warning.
17233 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
17235 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
17236 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
17237 isn't needed on 32-bit machines.
17239 * buffer.c (Fgenerate_new_buffer_name):
17240 Use EMACS_INT for count, not int.
17241 (advance_to_char_boundary): Return EMACS_INT, not int.
17243 * data.c (Qcompiled_function): Now static.
17245 * window.c (window_body_lines): Now static.
17247 * image.c (gif_load): Rename local to avoid shadowing.
17249 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
17250 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
17251 * alloc.c (make_save_value): Integer argument is now of type
17252 ptrdiff_t, not int.
17253 (mark_object): Use ptrdiff_t, not int.
17254 * lisp.h (pD): New macro.
17255 * print.c (print_object): Use it.
17257 * alloc.c: Use EMACS_INT, not int, to count objects.
17258 (total_conses, total_markers, total_symbols, total_vector_size)
17259 (total_free_conses, total_free_markers, total_free_symbols)
17260 (total_free_floats, total_floats, total_free_intervals)
17261 (total_intervals, total_strings, total_free_strings):
17262 Now EMACS_INT, not int. All uses changed.
17263 (Fgarbage_collect): Compute overall total using a double, so that
17264 integer overflow is less likely to be a problem. Check for overflow
17265 when converting back to an integer.
17266 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
17267 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
17268 These were 'int' variables that could overflow on 64-bit hosts;
17269 they were never used, so remove them instead of repairing them.
17270 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
17271 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
17272 Previously, this ceilinged at INT_MAX, but that doesn't work on
17274 (allocate_pseudovector): Don't use EMACS_INT when int would do.
17276 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
17277 (allocate_vectorlike): Check for ptrdiff_t overflow.
17278 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
17279 when a (possibly-narrower) signed value would do just as well.
17280 We prefer using signed arithmetic, to avoid comparison confusion.
17282 * alloc.c: Catch some string size overflows that we were missing.
17283 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
17284 for convenience in STRING_BYTES_MAX.
17285 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
17286 The definition here is exact; the one in lisp.h was approximate.
17287 (allocate_string_data): Check for string overflow. This catches
17288 some instances we weren't catching before. Also, it catches
17289 size_t overflow on (unusual) hosts where SIZE_MAX <= min
17290 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
17291 and ptrdiff_t and EMACS_INT are both 64 bits.
17293 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
17294 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
17295 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
17297 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
17299 * alloc.c (Fmake_string): Check for out-of-range init.
17301 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
17303 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
17305 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
17307 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
17308 xg_get_default_scrollbar_width.
17310 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
17311 (int_gtk_range_get_value): Move to the scroll bar part of the file.
17312 (style_changed_cb): Call update_theme_scrollbar_width and call
17313 x_set_scroll_bar_default_width and xg_frame_set_char_size for
17314 all frames (Bug#8505).
17315 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
17316 Call gtk_window_set_resizable if HAVE_GTK3.
17317 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
17318 and height if HAVE_GTK3 (Bug#8505).
17319 (scroll_bar_width_for_theme): New variable.
17320 (update_theme_scrollbar_width): New function.
17321 (xg_get_default_scrollbar_width): Move code to
17322 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
17323 (xg_initialize): Call update_theme_scrollbar_width.
17325 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
17327 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
17329 2011-06-12 Martin Rudalics <rudalics@gmx.at>
17331 * frame.c (make_frame): Call other_buffer_safely instead of
17334 * window.c (temp_output_buffer_show): Call display_buffer with
17335 second argument Vtemp_buffer_show_specifiers and reset latter
17336 immediately after the call.
17337 (Vtemp_buffer_show_specifiers): New variable.
17338 (auto_window_vscroll_p, next_screen_context_lines)
17339 (Vscroll_preserve_screen_position): Remove leading asterisks from
17342 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
17344 Fix minor problems found by GCC 4.6.0 static checking.
17345 * buffer.c (Qclone_number): Remove for now, as it's unused.
17346 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
17347 (record_buffer): Remove unused local.
17348 * frame.c (other_visible_frames, frame_buffer_list): Now static.
17349 (set_frame_buffer_list): Remove; unused.
17350 * frame.h (other_visible_frames): Remove decl.
17351 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
17352 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
17353 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
17355 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
17356 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
17357 Define only if HAVE_GPM.
17358 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
17359 (update_hints_inhibit): Remove; never set. All uses removed.
17360 * widgetprv.h (emacsFrameClassRec): Remove decl.
17361 * window.c (delete_deletable_window): Now returns void, since it
17362 wasn't returning anything.
17363 (compare_window_configurations): Remove unused locals.
17364 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
17365 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.

17833 New error handlers.
17834 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
17835 Obey Vx_select_enable_clipboard_manager. Catch errors in
17836 x_clipboard_manager_save (Bug#8779).
17837 (Vx_select_enable_clipboard_manager): New variable.
17838 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
17840 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
17842 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
17844 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17846 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap

17853 2011-06-03 Eli Zaretskii <eliz@gnu.org>
17855 Support bidi reordering of text covered by display properties.
17857 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
17858 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
17859 (bidi_cache_search, bidi_cache_iterator_state)
17860 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
17861 (bidi_level_of_next_char, bidi_move_to_visually_next):
17862 Support character positions inside a run of characters covered by a
17864 (bidi_paragraph_init, bidi_resolve_explicit_1)
17865 (bidi_level_of_next_char): Call bidi_fetch_char and
17866 bidi_fetch_char_advance instead of FETCH_CHAR and
17867 FETCH_CHAR_ADVANCE.

17869 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
17871 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
17872 instead of using explicit *_CHAR codes.
17873 (bidi_resolve_explicit, bidi_resolve_weak):
17874 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
17875 bidirectional text is supported only in multibyte buffers.
17876 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
17877 it to initialize the frame_window_p member of struct bidi_it.
17878 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
17879 (bidi_resolve_explicit, bidi_resolve_weak)

17881 bidi_it->nchars is non-positive.
17882 (bidi_level_of_next_char): Don't try to lookup the cache for the
17883 next/previous character if nothing is cached there yet, or if we
17884 were just reseat()'ed to a new position.
17886 * xdisp.c (set_cursor_from_row): Set start and stop points
17887 according to the row's direction when priming the loop that looks
17888 for the glyph on which to display cursor.
17889 (single_display_spec_intangible_p): Function deleted.
17890 (display_prop_intangible_p): Reimplement to call
17891 handle_display_spec instead of single_display_spec_intangible_p.
17892 Accept 3 additional arguments needed by handle_display_spec.
17893 This fixes incorrect cursor motion across display property with complex
17894 values: lists, `(when COND...)' forms, etc.
17895 (single_display_spec_string_p): Support property values that are
17896 lists with the argument STRING its top-level element.
17897 (display_prop_string_p): Fix the condition for processing a
17898 property that is a list to be consistent with handle_display_spec.
17899 (handle_display_spec): New function, refactored from the
17900 last portion of handle_display_prop.
17901 (compute_display_string_pos): Accept additional argument
17902 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
17903 value of a `display' property is a "replacing spec".
17904 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
17905 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
17906 the display property, but just return a value indicating whether
17907 the display property will replace the characters it covers.
17908 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
17909 frame_window_p members of struct bidi_it.
17910 (compute_display_string_pos, compute_display_string_end):
17912 (push_it): Accept second argument POSITION, where pop_it should
17913 jump to continue iteration.
17914 (reseat_1): Initialize bidi_it.disp_pos.
17916 * keyboard.c (adjust_point_for_property): Adjust the call to
17917 display_prop_intangible_p to its new signature.
17919 * dispextern.h (struct bidi_it): New member frame_window_p.
17920 (bidi_init_it): Update prototypes.
17921 (display_prop_intangible_p): Update prototype.
17922 (compute_display_string_pos, compute_display_string_end):
17923 Declare prototypes.
17924 (struct bidi_it): New members nchars and disp_pos. ch_len is now
17927 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
17929 Malloc failure behavior now depends on size of allocation.
17930 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
17931 * lisp.h: Change signatures accordingly.
17932 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
17933 All callers changed. (Bug#8762)
17935 * gnutls.c: Use Emacs's memory allocators.
17936 Without this change, the gnutls library would invoke malloc etc.
17937 directly, which causes problems on non-SYNC_INPUT hosts, and which
17938 runs afoul of improving memory_full behavior. (Bug#8761)
17939 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
17940 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
17941 xfree instead of the default malloc, realloc, free.
17942 (Fgnutls_boot): No need to check for memory allocation failure,
17943 since xmalloc does that for us.
17945 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
17946 * category.c (hash_get_category_set):
17947 * ccl.c (ccl_driver):
17948 * charset.c (Fdefine_charset_internal):

17958 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
17959 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
17960 (Fsxhash, Fgethash, Fputhash, Fmaphash):
17961 * image.c (make_image, search_image_cache, lookup_image)
17962 (xpm_put_color_table_h):
17963 * lisp.h (struct Lisp_Hash_Table):
17964 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
17965 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
17966 for hashes and hash indexes, instead of 'unsigned' and 'int'.
17967 * alloc.c (allocate_vectorlike):
17968 Check for overflow in vector size calculations.
17969 * ccl.c (ccl_driver):
17970 Check for overflow when converting EMACS_INT to int.
17971 * fns.c, image.c: Remove unnecessary static decls that would otherwise
17972 need to be updated by these changes.
17973 * fns.c (make_hash_table, maybe_resize_hash_table):
17974 Check for integer overflow with large hash tables.
17975 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
17976 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
17977 (SXHASH_REDUCE): New macro.
17978 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
17979 Use it instead of discarding useful hash info with large hash values.
17980 (sxhash_float): New function.
17981 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
17982 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
17983 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
17984 Rewrite to use FIXNUM_BITS, as this simplifies things.
17985 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
17986 Adjust signatures to match updated version of code.
17987 (consing_since_gc): Now EMACS_INT, since a single hash table can
17988 use more than INT_MAX bytes.
17990 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
17992 Make it possible to build with GCC-4.6+ -O2 -flto.
17994 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
17996 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
17998 * minibuf.c (get_minibuffer, read_minibuf_unwind):
17999 Call minibuffer-inactive-mode.
18001 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
18003 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
18004 Update dependencies.
18006 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18008 * data.c (init_data): Remove code for UTS, this system is not
18011 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18013 Don't force ./temacs to start in terminal mode.
18015 * frame.c (make_initial_frame): Initialize faces in all cases, not
18016 only when CANNOT_DUMP is defined.
18017 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
18019 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18021 * dispnew.c (add_window_display_history): Use const for the string
18022 pointer. Remove declaration, not needed.
18024 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18026 Use 'inline', not 'INLINE'.
18027 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
18028 * alloc.c, fontset.c (INLINE): Remove.
18029 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
18030 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
18031 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
18032 * gmalloc.c (register_heapinfo): Use inline unconditionally.
18033 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
18035 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18037 Make it possible to run ./temacs.
18039 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
18040 syms_of_callproc does the same thing. Remove test for
18041 "initialized", do it in the caller.
18042 * emacs.c (main): Avoid calling set_initial_environment when dumping.
18044 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
18046 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
18047 (read_minibuf): Use get_minibuffer.
18048 (syms_of_minibuf): Use DEFSYM.
18049 (Qmetadata): New var.
18050 * data.c (Qbuffer): Don't make it static.
18051 (syms_of_data): Use DEFSYM.
18053 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18055 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
18056 (CCL_CODE_MIN): New macro.
18058 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
18060 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
18062 * eval.c (Qdebug): Now static.
18063 * lisp.h (Qdebug): Remove decl. This reverts a part of the
18064 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
18065 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
18067 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18069 * image.c: Various fixes to ImageMagick code comments.
18070 (Fimagemagick_types): Doc fix.
18072 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
18074 Minor fixes prompted by GCC 4.6.0 warnings.
18076 * xselect.c (converted_selections, conversion_fail_tag): Now static.
18078 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
18079 (x_clipboard_manager_save_all): Move extern decl to ...
18080 * xterm.h: ... here, so that it can be checked for consistency.
18082 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18084 * xselect.c (x_clipboard_manager_save_frame)
18085 (x_clipboard_manager_save_all): New functions.
18086 (Fx_clipboard_manager_save): Lisp function deleted.
18088 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
18089 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
18091 * xterm.h: Update prototype.
18093 2011-05-28 William Xu <william.xwl@gmail.com>
18095 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
18096 exiting (Bug#8239).
18098 2011-05-28 Jim Meyering <meyering@redhat.com>
18100 Avoid a sign-extension bug in crypto_hash_function.
18101 * fns.c (to_uchar): Define.
18102 (crypto_hash_function): Use it to convert some newly-signed
18103 variables to unsigned, to avoid sign-extension bugs. For example,
18104 without this change, (md5 "truc") would evaluate to
18105 45723a2aff78ff4fff7fff1114760e62 rather than the expected
18106 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
18107 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
18109 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18111 Integer overflow fixes.
18113 * dbusbind.c: Serial number integer overflow fixes.
18114 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
18115 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
18116 to hold a serial number that is too large for a fixnum.
18117 (Fdbus_method_return_internal, Fdbus_method_error_internal):
18118 Check for serial numbers out of range. Decode any serial number
18119 that was so large that it became a float. (Bug#8722)
18121 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
18122 (Fdbus_call_method, Fdbus_call_method_asynchronously):
18123 Use XFASTINT rather than XUINT when numbers are nonnegative.
18124 (xd_append_arg, Fdbus_method_return_internal):
18125 (Fdbus_method_error_internal): Likewise. Also, for unsigned
18126 arguments, check that Lisp number is nonnegative, rather than
18127 silently wrapping negative numbers around. (Bug#8722)
18128 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
18131 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
18133 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
18135 ccl: Add integer overflow checks.
18136 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
18137 (IN_INT_RANGE): New macros.
18138 (ccl_driver): Use them to check for integer overflow when
18139 decoding a CCL program. Many of the new checks are whether XINT (x)
18140 fits in int; it doesn't always, on 64-bit hosts. The new version
18141 doesn't catch all possible integer overflows, but it's an
18142 improvement. (Bug#8719)
18144 * alloc.c (make_event_array): Use XINT, not XUINT.
18145 There's no need for unsigned here.
18147 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
18148 This follows up to the 2011-05-06 change that substituted uintptr_t
18149 for EMACS_INT. This case wasn't caught back then.
18151 Rework Fformat to avoid integer overflow issues.
18152 * editfns.c: Include <float.h> unconditionally, as it's everywhere
18153 now (part of C89). Include <verify.h>.
18154 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
18155 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
18156 (Fformat): Avoid the prepass trying to compute sizes; it was only
18157 approximate and thus did not catch overflow reliably. Instead, walk
18158 through the format just once, formatting and computing sizes as we go,
18159 checking for integer overflow at every step, and allocating a larger
18160 buffer as needed. Keep track separately whether the format is
18161 multibyte. Keep only the most-recently calculated precision, rather
18162 than them all. Record whether each argument has been converted to
18163 string. Use EMACS_INT, not int, for byte and char and arg counts.
18164 Support field widths and precisions larger than INT_MAX. Avoid
18165 sprintf's undefined behavior with conversion specifications such as %#d
18166 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
18167 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
18168 formatting out-of-range floating point numbers with int
18169 formats. (Bug#8668)
18171 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
18173 * data.c: Avoid integer truncation in expressions involving floats.
18174 * data.c: Include <intprops.h>.
18175 (arith_driver): When there's an integer overflow in an expression
18176 involving floating point, convert the integers to floating point
18177 so that the resulting value does not suffer from catastrophic
18178 integer truncation. For example, on a 64-bit host (* 4
18179 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
18180 Do not rely on undefined behavior after integer overflow.
18182 merge count_size_as_multibyte, parse_str_to_multibyte
18183 * character.c, character.h (count_size_as_multibyte):
18184 Rename from parse_str_to_multibyte; all uses changed.
18185 Check for integer overflow.
18186 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
18187 since it's now a duplicate of the other. This is more of
18188 a character than a buffer op, so better that it's in character.c.
18189 * fns.c, print.c: Adjust to above changes.
18191 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
18193 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
18195 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18197 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18198 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
18199 (x_clipboard_manager_save): Now static.
18200 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
18202 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18203 (crypto_hash_function): Now static.
18204 Fix pointer signedness problems. Avoid unnecessary initializations.
18206 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
18208 * termhooks.h (Vselection_alist): Make it terminal-local.
18210 * terminal.c (create_terminal): Initialize it.
18212 * xselect.c: Support for clipboard managers.
18213 (Vselection_alist): Move to termhooks.h as terminal-local var.
18214 (LOCAL_SELECTION): New macro.
18215 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
18216 (symbol_to_x_atom): Remove gratuitous arg.
18217 (x_handle_selection_request, lisp_data_to_selection_data)
18218 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
18219 (x_own_selection, x_get_local_selection, x_convert_selection):
18220 New arg, specifying work frame. Use terminal-local Vselection_alist.
18221 (some_frame_on_display): Delete unused function.
18222 (Fx_own_selection_internal, Fx_get_selection_internal)
18223 (Fx_disown_selection_internal, Fx_selection_owner_p)
18224 (Fx_selection_exists_p): New optional frame arg.
18225 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
18226 (x_handle_selection_clear): Don't treat other terminals with the
18227 same keyboard specially. Use the terminal-local Vselection_alist.
18228 (x_clear_frame_selections): Use Frun_hook_with_args.
18230 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
18232 * xterm.h: Add support for those atoms.
18234 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
18236 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
18237 (converted_selections, conversion_fail_tag): New global variables.
18238 (x_selection_request_lisp_error): Free the above.
18239 (x_get_local_selection): Remove unnecessary code.
18240 (x_reply_selection_request): Args changed; handle arbitrary array
18241 of converted selections stored in converted_selections.
18242 Separate the XChangeProperty and SelectionNotify steps.
18243 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
18244 (x_convert_selection): New function.
18245 (x_handle_selection_event): Simplify.
18246 (x_get_foreign_selection): Don't ignore incoming requests while
18247 waiting for an answer; this will fail when we implement
18248 SAVE_TARGETS, and seems unnecessary anyway.
18249 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
18250 (Vx_sent_selection_functions): Doc fix.
18252 2011-05-26 Leo Liu <sdl.web@gmail.com>
18254 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
18256 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18258 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
18260 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
18261 for fringe update if it has periodic bitmap.
18262 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
18263 and fringe_bitmap_periodic_p.
18265 * fringe.c (get_fringe_bitmap_data): New function.
18266 (draw_fringe_bitmap_1, update_window_fringes): Use it.
18267 (update_window_fringes): Record periodicity of fringe bitmap in glyph
18268 row. Mark glyph row for fringe update if periodicity changed.
18270 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
18271 for fringe update unless it has periodic bitmap.
18273 2011-05-25 Kenichi Handa <handa@m17n.org>
18275 * xdisp.c (get_next_display_element): Set correct it->face_id for
18276 a static composition.
18278 2011-05-24 Leo Liu <sdl.web@gmail.com>
18281 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
18283 * fns.c (crypto_hash_function, Fsha1): New function.
18284 (Fmd5): Use crypto_hash_function.
18285 (syms_of_fns): Add Ssha1.
18287 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18289 * gnutls.c: Remove unused macros.
18290 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
18291 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
18292 Remove macros that are defined and never used.
18293 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
18295 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18297 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
18298 (Fx_get_selection_internal): Minor cleanup.
18299 (Fx_own_selection_internal): Rename arguments for consistency with
18302 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18304 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
18306 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18308 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
18310 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18312 * dispnew.c (scrolling_window): Don't exclude the case that the
18313 last enabled row in the desired matrix touches the bottom boundary.
18315 2011-05-21 Glenn Morris <rgm@gnu.org>
18317 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
18318 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
18319 and add some more files.
18321 2011-05-20 Eli Zaretskii <eliz@gnu.org>
18323 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
18324 report_file_error introduced by the change from 2011-05-07.
18326 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
18328 * systime.h (Time): Define only if emacs is defined.
18329 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
18330 where the include path doesn't have X11/X.h by default. See
18331 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
18333 2011-05-20 Kenichi Handa <handa@m17n.org>
18335 * composite.c (find_automatic_composition): Fix previous change.
18337 2011-05-20 Glenn Morris <rgm@gnu.org>
18339 * lisp.mk: New file, split from Makefile.in.
18340 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
18341 (shortlisp): Remove.
18342 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
18344 2011-05-19 Glenn Morris <rgm@gnu.org>
18346 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
18347 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
18348 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
18349 (lisp): Set the order to that of loadup.el.
18350 (shortlisp): Make it a copy of $lisp.
18351 (SOME_MACHINE_LISP): Remove.
18352 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
18353 Use just $shortlisp, not $SOME_MACHINE_LISP too.
18355 2011-05-18 Kenichi Handa <handa@m17n.org>
18357 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
18358 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
18359 (find_automatic_composition): Mostly rewrite for efficiency.
18361 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
18363 * makefile.w32-in: Update dependencies.
18365 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
18367 * menu.c: Include limits.h (fixes the MS-Windows build broken by
18368 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
18370 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
18372 Fix some integer overflow issues, such as string length overflow.
18374 * insdel.c (count_size_as_multibyte): Check for string overflow.
18376 * character.c (lisp_string_width): Check for string overflow.
18377 Use EMACS_INT, not int, for string indexes and lengths; in
18378 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
18379 the resulting string length overflows an EMACS_INT; instead,
18380 report a string overflow if no precision given. When checking for
18381 precision exhaustion, use a check that cannot possibly have
18382 integer overflow. (Bug#8675)
18383 * character.h (lisp_string_width): Adjust to new signature.
18385 * alloc.c (string_overflow): New function.
18386 (Fmake_string): Use it. This doesn't change behavior, but saves
18387 a few bytes and will simplify future changes.
18388 * character.c (string_escape_byte8): Likewise.
18389 * lisp.h (string_overflow): New decl.
18391 Fixups, following up to the user-interface timestamp change.
18392 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
18393 for UI timestamps, instead of unsigned long.
18394 * msdos.c (mouse_get_pos): Likewise.
18395 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
18396 * w32gui.h (Time): Define by including "systime.h" rather than by
18397 declaring it ourselves. (Bug#8664)
18399 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
18400 * image.c (clear_image_cache): Likewise.
18402 * term.c (term_mouse_position): Don't assume time_t wraparound.
18404 Be more systematic about user-interface timestamps.
18405 Before, the code sometimes used 'Time', sometimes 'unsigned long',
18406 and sometimes 'EMACS_UINT', to represent these timestamps.
18407 This change causes it to use 'Time' uniformly, as that's what X uses.
18408 This makes the code easier to follow, and makes it easier to catch
18409 integer overflow bugs such as Bug#8664.
18410 * frame.c (Fmouse_position, Fmouse_pixel_position):
18411 Use Time, not unsigned long, for user-interface timestamps.
18412 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
18413 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
18414 * keyboard.h (last_event_timestamp): Likewise.
18415 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
18416 * menu.h (xmenu_show): Likewise.
18417 * term.c (term_mouse_position): Likewise.
18418 * termhooks.h (struct input_event.timestamp): Likewise.
18419 (struct terminal.mouse_position_hook): Likewise.
18420 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
18421 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
18422 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
18423 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
18424 what it was before.
18425 * menu.h, termhooks.h: Include "systime.h", for Time.
18427 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
18428 Don't assume that the difference between two unsigned long values
18429 can fit into an integer. At this point, we know button_down_time
18430 <= event->timestamp, so the difference must be nonnegative, so
18431 there's no need to cast the result if double-click-time is
18432 nonnegative, as it should be; check that it's nonnegative, just in
18433 case. This bug is triggered when events are more than 2**31 ms
18434 apart (about 25 days). (Bug#8664)
18436 * xselect.c (last_event_timestamp): Remove duplicate decl.
18437 (x_own_selection): Remove needless cast to unsigned long.
18439 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
18440 that always fit in int. Use a sentinel instead of a counter, to
18441 avoid a temp and to allay GCC's concerns about possible int overflow.
18442 * frame.h (struct frame): Use int for menu_bar_items_used
18443 instead of EMACS_INT, since it always fits in int.
18445 * menu.c (grow_menu_items): Check for int overflow.
18447 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
18449 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
18450 Before, the code was not consistent. These values cannot exceed
18451 2**31 - 1 so there's no need to make them unsigned.
18452 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
18453 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
18454 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
18456 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
18458 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
18459 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
18460 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
18461 presumably because the widths might not match.
18463 * window.c (size_window): Avoid needless test at loop start.
18465 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
18467 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
18469 2011-05-12 Drew Adams <drew.adams@oracle.com>
18471 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
18473 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18475 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
18476 `width' to `bar_area_x' and `bar_area_width', respectively.
18477 (x_scroll_run): Take account of fringe background extension.
18479 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
18480 Rename local vars `left' and `width' to `bar_area_x' and
18481 `bar_area_width', respectively.
18482 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
18483 background extension.
18485 2011-05-10 Jim Meyering <meyering@redhat.com>
18487 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
18489 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
18491 * image.c (Finit_image_library): Return t for built-in image types,
18492 like pbm and xbm. (Bug#8640)
18494 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
18496 * w32menu.c (set_frame_menubar): Fix submenu allocation.
18498 2011-05-07 Eli Zaretskii <eliz@gnu.org>
18500 * w32console.c (Fset_screen_color): Doc fix.
18501 (Fget_screen_color): New function.
18502 (syms_of_ntterm): Defsubr it.
18504 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
18505 unlink the temporary file if Fcall_process didn't create it in the
18507 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
18508 child process will be redirected to a file specified with `:file'.
18509 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
18510 cue to call_process_cleanup not to close that handle.
18512 2011-05-07 Ben Key <bkey76@gmail.com>
18514 * makefile.w32-in: The bootstrap-temacs rule now makes use of
18515 one of two shell specific rules, either bootstrap-temacs-CMD or
18516 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
18517 to the previous implementation of the bootstrap-temacs rule.
18518 The bootstrap-temacs-CMD rule is similar to the previous
18519 implementation of the bootstrap-temacs rule except that it
18520 makes use of the ESC_CFLAGS variable instead of the CFLAGS
18523 These changes, along with some changes to nt/configure.bat,
18524 nt/gmake.defs, and nt/nmake.defs, are required to extend my
18525 earlier fix to add support for --cflags and --ldflags options
18526 that include quotes so that it works whether make uses cmd or
18529 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
18531 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
18532 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
18534 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
18535 a string. Handle both cases.
18536 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
18537 (Fdbus_register_method): Use Qinvalid_function.
18539 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18541 * makefile.w32-in: Update dependencies.
18542 (LISP_H): Add inttypes.h and stdin.h.
18543 (PROCESS_H): Add unistd.h.
18545 2011-05-06 Eli Zaretskii <eliz@gnu.org>
18547 * lread.c: Include limits.h (fixes the MS-Windows build broken by
18548 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
18550 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
18552 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
18554 * term.c (vfatal): Remove stray call to va_end.
18555 It's not needed and the C Standard doesn't allow it here anyway.
18557 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
18558 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
18560 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
18563 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
18565 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
18567 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
18569 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
18571 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
18573 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
18574 * charset.c (Fdefine_charset_internal): Don't initialize
18575 charset.code_space[15]. The value was garbage, on hosts with
18576 32-bit int (Bug#8600).
18578 * lread.c (read_integer): Be more consistent with string-to-number.
18579 Use string_to_number to do the actual conversion; this avoids
18580 rounding errors and fixes some other screwups. Without this fix,
18581 for example, #x1fffffffffffffff was misread as -2305843009213693952.
18582 (digit_to_number): Move earlier, for benefit of read_integer.
18583 Return -1 if the digit is out of range for the base, -2 if it is
18584 not a digit in any supported base. (Bug#8602)
18586 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
18588 * dispnew.c (scrolling_window): Return 1 if we scrolled,
18589 to match comment at start of function. This also removes a
18590 GCC warning about overflow in a 32+64-bit port.
18592 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
18594 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
18595 Reported by Stefan Monnier in
18596 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
18597 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18598 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
18600 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
18601 (EMACS_UINTPTR): Likewise, with uintptr_t.
18603 * lisp.h: Prefer 64-bit EMACS_INT if available.
18604 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
18605 on 32-bit hosts that have 64-bit int, so that they can access
18607 However, temporarily disable this change unless the temporary
18608 symbol WIDE_EMACS_INT is defined.
18610 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
18612 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
18613 This removes an assumption that EMACS_INT and long are the same
18614 width as pointers. The assumption is true for Emacs porting targets
18615 now, but we want to make other targets possible.
18616 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
18617 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
18618 In the rest of the code, change types of integers that hold casted
18619 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
18620 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
18621 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
18622 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
18623 No need to cast type when ORing.
18624 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
18625 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
18626 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
18627 assume EMACS_INT is the same width as char *.
18628 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
18629 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
18630 Remove no-longer-needed casts.
18631 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
18632 (xg_tool_bar_help_callback, xg_make_tool_item):
18633 Use EMACS_INTPTR to hold an integer
18634 that will be cast to void *; this can avoid a GCC warning
18635 if EMACS_INT is not the same width as void *.
18636 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
18637 * xdisp.c (display_echo_area_1, resize_mini_window_1):
18638 (current_message_1, set_message_1):
18639 Use a local to convert to proper width without a cast.
18640 * xmenu.c (dialog_selection_callback): Likewise.
18642 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
18643 Also, don't assume VALBITS / RAND_BITS is less than 5,
18644 and don't rely on undefined behavior when shifting a 1 left into
18646 * lisp.h (get_random): Change signature to match.
18648 * lread.c (hash_string): Use size_t, not int, for hash computation.
18649 Normally we prefer signed values; but hashing is special, because
18650 it's better to use unsigned division on hash table sizes so that
18651 the remainder is nonnegative. Also, size_t is the natural width
18652 for hashing into memory. The previous code used 'int', which doesn't
18653 retain enough info to hash well into very large tables.
18654 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
18656 * dbusbind.c: Don't possibly lose pointer info when converting.
18657 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18658 Use XPNTR rather than XHASH, so that the high-order bits of
18659 the pointer aren't lost when converting through void *.
18661 * eval.c (Fautoload): Don't double-shift a pointer.
18663 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
18665 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18667 * gnutls.c (DEF_GNUTLS_FN):
18668 * image.c (DEF_IMGLIB_FN): Make function pointers static.

18746 * process.c: Include lisp.h before w32.h, not after.
18747 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
18748 instead of gnutls_record_check_pending.
18750 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
18752 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
18754 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options

18800 rather than `XVECTOR (FOO)->size'.
18802 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
18803 inttypes.h, as a gnulib replacement is used if it not available in
18806 2011-04-21 Eli Zaretskii <eliz@gnu.org>
18808 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
18809 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
18810 of MOST_POSITIVE_FIXNUM. (Bug#8528)

18813 will grow beyond MOST_POSITIVE_FIXNUM.
18814 (decode_coding_emacs_mule): Abort if there isn't enough place in
18815 charbuf for the composition carryover bytes. Reserve an extra
18816 space for up to 2 characters produced in a loop.
18817 (decode_coding_iso_2022): Abort if there isn't enough place in
18818 charbuf for the composition carryover bytes.
18820 2011-04-21 Eli Zaretskii <eliz@gnu.org>
18822 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
18823 aborting when %lld or %lll format is passed.
18824 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
18825 %llo or %llx format is passed. (Bug#8545)
18827 * window.c (window_scroll_line_based): Use a marker instead of
18828 simple variables to record original value of point. (Bug#7952)
18830 * doprnt.c (doprnt): Fix the case where a multibyte sequence
18831 produced by %s or %c overflows available buffer space. (Bug#8545)
18833 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
18835 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
18836 (SIZE_MAX): Move defn after all includes, as they might #define it.
18838 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18840 * w32.c (init_environment): Warn about defaulting HOME to C:\.
18842 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18844 * keyboard.c (Qdelayed_warnings_hook): Define.
18845 (command_loop_1): Run `delayed-warnings-hook'
18846 if Vdelayed_warnings_list is non-nil.
18847 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
18848 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
18850 2011-04-28 Eli Zaretskii <eliz@gnu.org>
18852 * doprnt.c (doprnt): Don't return value smaller than the buffer
18853 size if the message was truncated. (Bug#8545).
18855 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18857 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
18858 (Fx_window_property): #if-0 the whole functions, not just the bodies.
18860 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18862 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
18864 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
18866 * makefile.w32-in: Update dependencies.
18868 2011-04-27 Eli Zaretskii <eliz@gnu.org>
18870 Improve `doprnt' and its usage. (Bug#8545)
18871 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
18872 `format_end'. Remove support for %l as a conversion specifier.
18873 Don't use xrealloc. Improve diagnostics when the %l size modifier
18874 is used. Update the commentary.
18876 * eval.c (verror): Simplify calculation of size_t.
18878 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
18881 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
18883 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
18886 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18888 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
18889 This makes this file independent of the recent pseudovector change.
18891 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
18893 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
18895 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
18896 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
18897 Remove unused local.
18898 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
18900 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
18901 GCC 4.6.0 optimizes based on type-based alias analysis.
18902 For example, if b is of type struct buffer * and v of type struct
18903 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
18904 != &v->size, and therefore "v->size = 1; b->size = 2; return
18905 v->size;" must therefore return 1. This assumption is incorrect
18906 for Emacs, since it type-puns struct Lisp_Vector * with many other
18907 types. To fix this problem, this patch adds a new type struct
18908 vectorlike_header that documents the constraints on layout of vectors
18909 and pseudovectors, and helps optimizing compilers not get fooled
18910 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
18911 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
18912 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
18914 (XSETPVECTYPE): Rewrite in terms of new macro.
18915 (XSETPVECTYPESIZE): New macro, specifying both type and size.
18916 This is a bit clearer, and further avoids the possibility of
18917 undesirable aliasing.
18918 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
18919 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
18920 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
18921 since Lisp_Subr is a special case (no "next" field).
18922 (ASIZE): Now uses header.size rather than size.
18923 All previous uses of XVECTOR (foo)->size replaced to use this macro,
18924 to avoid the hassle of writing XVECTOR (foo)->header.size.
18925 (struct vectorlike_header): New type.
18926 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
18927 object, to help avoid aliasing.
18928 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
18929 (SUBRP): Likewise, since Lisp_Subr is a special case.
18930 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
18931 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
18932 (struct Lisp_Hash_Table): Combine first two members into a single
18933 struct vectorlike_header member. All uses of "size" and "next" members
18934 changed to be "header.size" and "header.next".
18935 * buffer.h (struct buffer): Likewise.
18936 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
18937 * frame.h (struct frame): Likewise.
18938 * process.h (struct Lisp_Process): Likewise.
18939 * termhooks.h (struct terminal): Likewise.
18940 * window.c (struct save_window_data, struct saved_window): Likewise.
18941 * window.h (struct window): Likewise.
18942 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
18943 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
18944 * buffer.c (init_buffer_once): Likewise.
18945 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
18947 * process.c (Fformat_network_address): Use local var for size,
18950 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
18952 Make the Lisp reader and string-to-float more consistent (Bug#8525)
18953 * data.c (atof): Remove decl; no longer used or needed.
18954 (digit_to_number): Move to lread.c.
18955 (Fstring_to_number): Use new string_to_number function, to be
18956 consistent with how the Lisp reader treats infinities and NaNs.
18957 Do not assume that floating-point numbers represent EMACS_INT
18958 without losing information; this is not true on most 64-bit hosts.
18959 Avoid double-rounding errors, by insisting on integers when
18960 parsing non-base-10 numbers, as the documentation specifies.
18961 * lisp.h (string_to_number): New decl, replacing ...
18962 (isfloat_string): Remove.
18963 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
18964 (read1): Do not accept +. and -. as integers; this
18965 appears to have been a coding error. Similarly, do not accept
18966 strings like +-1e0 as floating point numbers. Do not report
18967 overflow for integer overflows unless the base is not 10 which
18968 means we have no simple and reliable way to continue.
18969 Break out the floating-point parsing into a new
18970 function string_to_number, so that Fstring_to_number parses
18971 floating point numbers consistently with the Lisp reader.
18972 (digit_to_number): Move here from data.c. Make it static inline.
18973 (E_CHAR, EXP_INT): Remove, replacing with ...
18974 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
18975 (string_to_number): New function, replacing isfloat_string.
18976 This function checks for valid syntax and produces the resulting
18977 Lisp float number too. Rework it so that string-to-number
18978 no longer mishandles examples like "1.0e+". Use strtoumax,
18979 so that overflow for non-base-10 numbers is reported only when
18980 there's no portable and simple way to convert to floating point.
18982 * textprop.c (set_text_properties_1): Rewrite for clarity,
18983 and to avoid GCC warning about integer overflow.
18985 * intervals.h (struct interval): Use EMACS_INT for members
18986 where EMACS_UINT might cause problems. See
18987 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
18988 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
18989 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
18991 (offset_intervals): Tell GCC not to worry about length overflow
18992 when negating a negative length.
18994 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
18995 (overrun_check_free): Likewise.
18997 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
18998 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
19001 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19002 (gnutls_make_error): Rename local to avoid shadowing.
19003 (gnutls_emacs_global_deinit): ifdef out; not used.
19004 (Fgnutls_boot): Use const for pointer to readonly storage.
19005 Comment out unused local. Fix pointer signedness problems.
19007 * lread.c (openp): Don't stuff size_t into an 'int'.
19008 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
19009 about possible signed overflow.
19011 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19012 (GDK_KEY_g): Don't define if already defined.
19013 (xg_prepare_tooltip): Avoid pointer signedness problem.
19014 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
19016 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
19017 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
19019 * xfns.c (Fx_window_property): Simplify a bit,
19020 to make a bit faster and to avoid GCC 4.6.0 warning.
19021 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
19023 * fns.c (internal_equal): Don't assume size_t fits in int.
19025 * alloc.c (compact_small_strings): Tighten assertion a little.
19027 Replace pEd with more-general pI, and fix some printf arg casts.
19028 * lisp.h (pI): New macro, generalizing old pEd macro to other
19029 conversion specifiers. For example, use "...%"pI"d..." rather
19030 than "...%"pEd"...".
19031 (pEd): Remove. All uses replaced with similar uses of pI.
19032 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
19033 * alloc.c (check_pure_size): Don't overflow by converting size to int.
19034 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
19035 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
19036 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
19037 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
19038 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
19040 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
19041 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
19042 * print.c (safe_debug_print, print_object): Likewise.
19043 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
19045 Use pI instead of if-then-else-abort. Use %p to avoid casts,
19046 avoiding the 0 flag, which is not portable.
19047 * process.c (Fmake_network_process): Use pI to avoid cast.
19048 * region-cache.c (pp_cache): Likewise.
19049 * xdisp.c (decode_mode_spec): Likewise.
19050 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
19051 behavior on 64-bit hosts with printf arg.
19052 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
19053 (x_stop_queuing_selection_requests): Likewise.
19054 (x_get_window_property): Don't truncate byte count to an 'int'
19057 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
19058 here, since it parses constructs like leading '-' and spaces,
19059 which are not wanted; and it overflows with large numbers.
19060 Instead, simply match F[0-9]+, which is what is wanted anyway.
19062 * alloc.c: Remove unportable assumptions about struct layout.
19063 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
19064 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
19065 (allocate_vectorlike, make_pure_vector): Use the new macros,
19066 plus offsetof, to remove unportable assumptions about struct layout.
19067 These assumptions hold on all porting targets that I know of, but
19068 they are not guaranteed, they're easy to remove, and removing them
19069 makes further changes easier.
19071 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
19072 This doesn't fix a bug but makes the code clearer.
19073 (string_overrun_cookie): Now const. Use initializers that
19074 don't formally overflow signed char, to avoid warnings.
19075 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
19076 can cause Emacs to crash when string overrun checking is enabled.
19077 (allocate_buffer): Don't assume sizeof (struct buffer) is a
19078 multiple of sizeof (EMACS_INT); it need not be, if
19079 alignof(EMACS_INT) < sizeof (EMACS_INT).
19080 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
19082 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
19084 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
19086 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>

19941 * xdisp.c (redisplay_window): Don't try to determine the character
19942 position of the scroll margin if the window start point w->startp
19943 is outside the buffer's accessible region. (Bug#8468)
19945 2011-04-10 Eli Zaretskii <eliz@gnu.org>
19947 Fix write-region and its subroutines for buffers > 2GB.

19959 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>

19980 4.6.0 generate slightly better code.
19982 * ftfont.c: Distingish more carefully between FcChar8 and char.
19983 The previous code passed unsigned char * to a functions like
19984 strlen and xstrcasecmp that expect char *, which does not
19985 conform to the C standard.
19986 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
19987 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
19988 char * when the C standard requires it.
19990 * keyboard.c (read_char): Remove unused var.
19992 * eval.c: Port to Windows vsnprintf (Bug#8435).
19993 Include <limits.h>.
19994 (SIZE_MAX): Define if the headers do not.
19995 (verror): Do not give up if vsnprintf returns a negative count.
19996 Instead, grow the buffer. This ports to Windows vsnprintf, which
19997 does not conform to C99. Problem reported by Eli Zaretskii.
19998 Also, simplify the allocation scheme, by avoiding the need for
19999 calling realloc, and removing the ALLOCATED variable.
20001 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
20003 Remove invocations of doprnt, as Emacs now uses vsnprintf.
20004 But keep the doprint source code for now, as we might revamp it
20005 and use it again (Bug#8435).
20006 * lisp.h (doprnt): Remove.
20007 * Makefile.in (base_obj): Remove doprnt.o.
20008 * deps.mk (doprnt.o): Remove.
20010 error: Print 32- and 64-bit integers portably (Bug#8435).
20011 Without this change, on typical 64-bit hosts error ("...%d...", N)
20012 was used to print both 32- and 64-bit integers N, which relied on
20013 undefined behavior.
20014 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
20015 * lisp.h (error, verror): Mark as printf-like functions.
20016 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
20017 Report overflow in size calculations when allocating printf buffer.
20018 Do not truncate output string at its first null byte.
20019 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
20020 Truncate the output at a character boundary, since vsnprintf does not
20022 * charset.c (check_iso_charset_parameter): Convert internal
20023 character to string before calling 'error', since %c now has the
20025 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
20026 overflow when computing char to be passed to 'error'. Do not
20027 pass Lisp_Object to 'error'; pass the integer instead.
20028 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
20029 formatted with plain %d.
20031 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
20033 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
20035 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
20037 * xterm.c (x_catch_errors): Remove duplicate declaration.
20039 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
20041 * xdisp.c, lisp.h (message_nolog): Remove; unused.
20043 2011-04-10 Jim Meyering <meyering@redhat.com>
20045 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
20046 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
20047 return ssize_t not "int", and use size_t as the buffer length.
20048 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
20049 * gnutls.h: Update declarations.
20050 * process.c (read_process_output): Use ssize_t, to match.
20051 (send_process): Likewise.
20053 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20055 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
20057 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20059 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
20060 Use unsigned char, to match FcChar8 type definition.
20062 * xterm.c (handle_one_xevent):
20063 * xmenu.c (create_and_show_popup_menu):
20064 * xselect.c (x_decline_selection_request)
20065 (x_reply_selection_request): Avoid type-punned deref of X events.
20067 2011-04-09 Eli Zaretskii <eliz@gnu.org>
20069 Fix some uses of `int' instead of EMACS_INT.
20070 * search.c (string_match_1, fast_string_match)
20071 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
20072 (scan_buffer, find_next_newline_no_quit)
20073 (find_before_next_newline, search_command, Freplace_match)
20074 (Fmatch_data): Make some `int' variables be EMACS_INT.
20076 * xdisp.c (display_count_lines): 3rd argument and return value now
20077 EMACS_INT. All callers changed.
20078 (pint2hrstr): Last argument is now EMACS_INT.
20080 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
20081 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
20082 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
20083 (decode_coding_utf_16, decode_coding_emacs_mule)
20084 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
20085 (decode_coding_ccl, decode_coding_charset)
20086 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
20087 (decode_coding_iso_2022, decode_coding_emacs_mule)
20088 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
20089 <char_offset, last_offset>: Declare EMACS_INT.

20091 (encode_coding_emacs_mule, encode_invocation_designation)
20092 (encode_designation_at_bol, encode_coding_iso_2022)
20093 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
20094 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
20096 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
20097 (encode_invocation_designation): Last argument P_NCHARS is now
20099 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
20100 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
20102 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
20105 * ccl.c (Fccl_execute_on_string): Declare some variables
20108 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
20110 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
20112 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
20114 * process.c (Fformat_network_address): Doc fix.
20116 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)

20120 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
20122 * keyboard.c (read_char): Call Lisp function help-form-show,
20123 instead of using internal_with_output_to_temp_buffer.
20124 (Qhelp_form_show): New var.
20125 (syms_of_keyboard): Use DEFSYM macro.
20127 * print.c (internal_with_output_to_temp_buffer): Function deleted.
20129 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
20131 2011-04-06 Chong Yidong <cyd@stupidchicken.com>

20140 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
20142 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
20144 Fix more problems found by GCC 4.6.0's static checks.

20148 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
20150 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
20152 * xdisp.c (vmessage): Mark as a printf-like function.
20154 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
20156 * sound.c (sound_warning): Don't crash if arg contains a printf format.
20158 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
20159 printf-like functions.
20160 (tiff_load): Add casts to remove these marks before passing them
20161 to system-supplied API.
20163 * eval.c (Fsignal): Remove excess argument to 'fatal'.
20165 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
20166 This avoids several warnings with gcc -Wstrict-overflow.
20167 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
20168 directly, rather than having caller test rule sign. This avoids
20169 some unnecessary tests.
20170 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
20171 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
20172 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
20174 * xfont.c (xfont_text_extents): Remove var that was set but not used.
20175 (xfont_open): Avoid unnecessary tests.
20177 * composite.c (composition_gstring_put_cache): Use unsigned integer.
20179 * composite.h, composite.c (composition_gstring_put_cache):
20180 Use EMACS_INT, not int, for length.

20183 breaking out part of COMPOSITION_DECODE_RULE.
20184 (COMPOSITION_DECODE_RULE): Use it.
20185 * composite.c (get_composition_id): Remove unused local vars,
20186 by using the new macro.
20188 * textprop.c (set_text_properties_1): Change while to do-while,
20189 since the condition is always true at first.
20191 * intervals.c (graft_intervals_into_buffer): Mark var as used.
20192 (interval_deletion_adjustment): Return unsigned value.
20195 * process.c (list_processes_1, create_pty, read_process_output):
20196 (exec_sentinel): Remove vars that were set but not used.
20197 (create_pty): Remove unnecessary "volatile"s.

20205 (update_syntax_table): Use unsigned instead of int.
20207 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
20208 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
20209 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
20211 * print.c (print_error_message): Avoid int overflow.
20213 * font.c (font_list_entities): Redo for clarity,
20214 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
20216 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
20217 (font_score): Avoid potential overflow in diff calculation.
20219 * fns.c (substring_both): Remove var that is set but not used.
20220 (sxhash): Redo loop for clarity and to avoid wraparound warning.
20222 * eval.c (funcall_lambda): Rename local to avoid shadowing.
20224 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
20225 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
20226 can always succeed if overflow has undefined behavior.
20228 * search.c (boyer_moore, wordify): Remove vars set but not used.
20229 (wordify): Omit three unnecessary tests.
20231 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
20232 All callers changed. This avoids the need for an unused var.
20234 * casefiddle.c (casify_region): Remove var that is set but not used.
20236 * dired.c (file_name_completion): Remove var that is set but not used.
20238 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
20240 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
20241 (Finsert_file_contents): Remove unnecessary code checking fd.
20243 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
20244 Check for integer overflow on size calculations.
20246 * buffer.c (Fprevious_overlay_change): Remove var that is set
20249 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
20250 Remove vars that are set but not used.
20251 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
20252 (timer_check_2): Mark vars as initialized.
20254 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
20256 * image.c (lookup_image): Remove var that is set but not used.
20257 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
20259 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
20260 that are set but not used.
20262 * xfns.c (make_invisible_cursor): Don't return garbage
20263 if XCreateBitmapFromData fails (Bug#8410).
20265 * xselect.c (x_get_local_selection, x_handle_property_notify):
20266 Remove vars that are set but not used.
20268 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
20269 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
20271 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
20272 Remove var that is set but not used.
20273 (scroll_bar_windows_size): Now size_t, not int.
20274 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
20275 Check for overflow.
20277 * xfaces.c (realize_named_face): Remove vars that are set but not used.
20278 (map_tty_color) [!defined MSDOS]: Likewise.
20280 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
20282 * coding.c: Remove vars that are set but not used.
20283 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
20284 All callers changed.
20285 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
20286 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
20287 (decode_coding_charset): Remove vars that are set but not used.
20289 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
20290 that is set but not used.
20292 * print.c (print_object): Remove var that is set but not used.
20294 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
20295 The gnulib version avoids calling malloc in the usual case,
20296 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
20297 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
20298 * filelock.c (current_lock_owner): Likewise.
20299 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
20300 * sysdep.c: Include allocator.h, careadlinkat.h.
20301 (emacs_no_realloc_allocator): New static constant.
20302 (emacs_readlink): New function.
20303 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
20304 ../lib/careadlinkat.h.
20306 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
20308 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
20309 first non-nil return value).
20311 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
20313 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
20314 if not defined (Bug#8403).

20323 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
20324 and thereabouts. All callers changed.
20325 (get_per_char_metric): Remove parameter `f', unused since
20326 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
20328 2011-04-02 Jim Meyering <meyering@redhat.com>
20330 do not dereference NULL upon failed strdup
20331 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
20332 (ns_get_family): Likewise.
20334 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
20336 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
20338 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
20340 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
20343 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
20345 Add lexical binding.
20347 * window.c (Ftemp_output_buffer_show): New fun.
20348 (Fsave_window_excursion):

20356 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
20358 (syms_of_lread): Declare `lexical-binding'.
20360 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
20362 * keyboard.c (eval_dyn): New fun.
20363 (menu_item_eval_property): Use it.
20365 * image.c (parse_image_spec): Use Ffunctionp.
20367 * fns.c (concat, mapcar1): Accept byte-code-functions.
20369 * eval.c (Fsetq): Handle lexical vars.
20370 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
20371 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
20372 (FletX, Flet): Obey lexical binding.
20373 (Fcommandp): Handle closures.
20374 (Feval): New `lexical' arg.
20375 (eval_sub): New function extracted from Feval. Use it almost
20376 everywhere where Feval was used. Look up vars in lexical env.
20378 (Ffunctionp): Move from subr.el.
20379 (Ffuncall): Handle closures.
20380 (apply_lambda): Remove `eval_flags'.
20381 (funcall_lambda): Handle closures and new byte-code-functions.
20382 (Fspecial_variable_p): New function.
20383 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
20384 but without exporting it to Lisp.
20386 * doc.c (Fdocumentation, store_function_docstring):
20387 * data.c (Finteractive_form): Handle closures.
20389 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
20392 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
20394 (exec_byte_code): New function extracted from Fbyte_code to handle new
20395 calling convention for byte-code-functions. Add new byte-codes.
20397 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
20399 * alloc.c (Fmake_symbol): Init new `declared_special' field.
20401 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20403 * xdisp.c (redisplay_internal): Fix prototype.
20405 2011-03-31 Eli Zaretskii <eliz@gnu.org>
20407 * xdisp.c (SCROLL_LIMIT): New macro.
20408 (try_scrolling): Use it when setting scroll_limit.
20409 Limit scrolling to 100 screen lines.
20410 (redisplay_window): Even when falling back on "recentering",
20411 position point in the window according to scroll-conservatively,
20412 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
20414 (try_scrolling): When point is above the window, allow searching
20415 as far as scroll_max, or one screenful, to compute vertical
20416 distance from PT to the scroll margin position. This prevents
20417 try_scrolling from unnecessarily failing when
20418 scroll-conservatively is set to a value slightly larger than the
20419 window height. Clean up the case of PT below the margin at bottom
20420 of window: scroll_max can no longer be INT_MAX. When aggressive
20421 scrolling is in use, don't let point enter the opposite scroll
20422 margin as result of the scroll.
20423 (syms_of_xdisp) <scroll-conservatively>: Document the
20424 threshold of 100 lines for never-recentering scrolling.
20426 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20428 * dispextern.h (move_it_by_lines):

20431 (message_log_check_duplicate): Remove parameters `prev_bol' and
20432 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
20433 (redisplay_internal): Remove parameter `preserve_echo_area',
20434 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
20436 * indent.c (Fvertical_motion):
20437 * window.c (window_scroll_pixel_based, Frecenter):
20438 Don't pass `need_y_p' to `move_it_by_lines'.
20440 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
20442 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
20443 steal a few bits to be more compact.
20444 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
20445 Remove unneeded casts.
20447 * bytecode.c (Fbyte_code): CAR and CDR can GC.
20449 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
20451 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
20452 binding" message (bug#7967).
20454 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
20456 Fix more problems found by GCC 4.6.0's static checks.
20458 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
20459 Remove unused local var.
20461 * editfns.c (Fmessage_box): Remove unused local var.
20463 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
20464 (note_mode_line_or_margin_highlight, note_mouse_highlight):
20465 Omit unused local vars.
20466 * window.c (shrink_windows): Omit unused local var.
20467 * menu.c (digest_single_submenu): Omit unused local var.
20468 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
20469 Omit unused local var.
20471 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
20472 Don't assume string length fits in int.
20473 (keyremap_step, read_key_sequence): Use size_t for sizes.
20474 (read_key_sequence): Don't check last_real_key_start redundantly.
20476 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
20477 instead of alloca (Bug#8344).
20479 * eval.c (Fbacktrace): Don't assume nargs fits in int.
20480 (Fbacktrace_frame): Don't assume nframes fits in int.
20482 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
20484 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
20487 * term.c (produce_glyphless_glyph): Remove unnecessary test.
20489 * cm.c (calccost): Turn while-do into do-while, for clarity.
20491 * keyboard.c (syms_of_keyboard): Use the same style as later
20492 in this function when indexing through an array. This also
20493 works around GCC bug 48267.
20495 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
20497 * xselect.c (x_check_property_data): Return correct size (Bug#8335).

20500 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
20502 * keyboard.c, keyboard.h (num_input_events): Now size_t.
20503 This avoids undefined behavior on integer overflow, and is a bit
20504 more convenient anyway since it is compared to a size_t variable.
20506 Variadic C functions now count arguments with size_t, not int.
20507 This avoids an unnecessary limitation on 64-bit machines, which
20508 caused (substring ...) to crash on large vectors (Bug#8344).
20509 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
20510 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
20511 All variadic functions and their callers changed accordingly.
20512 (struct gcpro.nvars): Now size_t, not int. All uses changed.

20516 (internal_condition_case_n, run_hook_with_args, apply_lambda)
20517 (funcall_lambda, mark_backtrace): Likewise.
20518 * fns.c (concat): Likewise.
20519 * frame.c (x_set_frame_parameters): Likewise.
20520 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
20521 0 if not found, not -1. All callers changed.
20523 * alloc.c (garbage_collect): Don't assume stack size fits in int.
20524 (stack_copy_size): Now size_t, not int.
20525 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

20530 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
20531 All callers changed.
20533 * lisp.h (multibyte_char_to_unibyte):
20534 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
20535 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

20541 * xdisp.c (message_dolog, set_message_1): All callers changed.
20543 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
20545 * keyboard.c (safe_run_hook_funcall): New function.
20546 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
20547 don't set the hook to nil, but remove the offending function instead.
20548 (Qcommand_hook_internal): Remove, unused.
20549 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
20550 Vcommand_hook_internal.
20552 * eval.c (enum run_hooks_condition): Remove.
20553 (funcall_nil, funcall_not): New functions.
20554 (run_hook_with_args): Call each function through a `funcall' argument.
20555 Remove `cond' argument, now redundant.
20556 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
20557 (Frun_hook_with_args_until_failure): Adjust accordingly.
20558 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
20560 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
20562 * dispextern.h (string_buffer_position): Remove declaration.
20564 * print.c (strout): Remove parameter `multibyte', unused since
20565 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
20567 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
20568 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
20569 All callers changed.
20571 * w32.c (_wsa_errlist): Use braces for struct initializers.
20573 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
20574 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
20575 All callers changed.

20577 used outside xdisp.c).
20578 (cursor_row_p): Remove parameter `w', unused since
20579 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

20581 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
20582 All callers changed.
20584 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
20586 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

20615 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
20617 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
20619 * w32.c (read_unc_volume): Use parameter `henum', instead of
20620 global variable `wget_enum_handle'.
20622 * keymap.c (describe_vector): Remove parameters `indices' and
20623 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

20638 * gtkutil.c (xg_maybe_add_timer):
20639 * keyboard.c (readable_events):
20640 * process.c (wait_reading_process_output):
20641 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
20643 * insdel.c (adjust_markers_gap_motion):
20644 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.

20718 2011-03-23 Julien Danjou <julien@danjou.info>
20720 * term.c (Fsuspend_tty, Fresume_tty):
20721 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
20722 * window.c (temp_output_buffer_show):

20727 * editfns.c (save_excursion_restore):
20728 * cmds.c (internal_self_insert):
20729 * callint.c (Fcall_interactively):
20730 * buffer.c (Fkill_all_local_variables):
20731 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
20733 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
20734 unconditionally since it does the check itself.
20736 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
20738 Fix more problems found by GCC 4.5.2's static checks.
20740 * coding.c (encode_coding_raw_text): Avoid unnecessary test
20741 the first time through the loop, since we know p0 < p1 then.
20742 This also avoids a gcc -Wstrict-overflow warning.
20744 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
20745 leading to a memory leak, possible in functions like
20746 load_charset_map_from_file that can allocate an unbounded number
20747 of objects (Bug#8318).
20749 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
20750 that could (at least in theory) be that large.
20752 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
20753 This is less likely to overflow, and avoids undefined behavior if
20754 overflow does occur. All callers changed. Use strtoul to scan
20755 for the unsigned long integer.
20756 (pint2hrstr): Simplify and tune code slightly.
20757 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

20767 * fileio.c (Fcopy_file): Report error if fchown or fchmod
20770 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
20772 * process.c (Fmake_network_process): Use socklen_t, not int,
20773 where POSIX says socklen_t is required in portable programs.
20774 This fixes a porting bug on hosts like 64-bit HP-UX, where
20775 socklen_t is wider than int (Bug#8277).
20776 (Fmake_network_process, server_accept_connection):
20777 (wait_reading_process_output, read_process_output):
20780 * process.c: Rename or move locals to avoid shadowing.
20781 (list_processes_1, Fmake_network_process):
20782 (read_process_output_error_handler, exec_sentinel_error_handler):
20783 Rename or move locals.
20784 (Fmake_network_process): Define label "retry_connect" only if needed.
20785 (Fnetwork_interface_info): Fix pointer signedness.

20787 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
20788 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
20790 Make tparam.h and terminfo.c consistent.
20791 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
20792 Include tparam.h instead, since it declares them.
20793 * cm.h (PC): Remove extern decl; tparam.h now does this.
20794 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
20795 * terminfo.c: Include tparam.h, to check interfaces.
20796 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
20797 (tparam): Adjust signature to match interface in tparam.h;
20798 this removes some undefined behavior. Check that outstring and len
20799 are zero, which they always are with Emacs.
20800 * tparam.h (PC, BC, UP): New extern decls.
20802 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
20803 (xftfont_open): Rename locals to avoid shadowing.
20805 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
20806 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
20807 (OTF_TAG_SYM): Omit macro if not needed.
20808 (ftfont_list): Remove unused local.
20809 (get_adstyle_property, ftfont_pattern_entity):
20810 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
20811 Rename locals to avoid shadowing.
20813 * xfont.c (xfont_list_family): Mark var as initialized.
20815 * xml.c (make_dom): Now static.
20817 * composite.c (composition_compute_stop_pos): Rename local to
20819 (composition_reseat_it): Remove unused locals.
20820 (find_automatic_composition, composition_adjust_point): Likewise.
20821 (composition_update_it): Mark var as initialized.
20822 (find_automatic_composition): Mark vars as initialized,
20823 with a FIXME (Bug#8290).
20825 character.h: Rename locals to avoid shadowing.
20826 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
20827 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
20828 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
20829 (BUF_DEC_POS): Be more systematic about renaming local temporaries
20830 to avoid shadowing.
20832 * textprop.c (property_change_between_p): Remove; unused.
20834 * intervals.c (interval_start_pos): Now static.
20836 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
20838 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
20839 Rename locals to avoid shadowing.
20841 * sound.c (wav_play, au_play, Fplay_sound_internal):
20842 Fix pointer signedness.
20843 (alsa_choose_format): Remove unused local var.
20844 (wav_play): Initialize a variable to 0, to prevent undefined
20845 behavior (Bug#8278).
20847 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
20849 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
20851 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
20852 clobbering (Bug#8298).
20853 * sysdep.c (sys_subshell): Likewise.
20854 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
20856 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
20857 This should get cleaned up, so that child_setup has the
20858 same signature on all platforms.
20860 * callproc.c (call_process_cleanup): Now static.
20861 (relocate_fd): Rename locals to avoid shadowing.
20863 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
20865 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
20866 not to be necessary, and produces flickering.
20868 2011-03-20 Glenn Morris <rgm@gnu.org>
20870 * config.in: Remove file.
20872 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
20874 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
20875 are now in src/globals.h.
20876 (syms_of_minibuf): Remove spurious & from previous change.

21030 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21031 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
21032 to use the following functions instead of these macros.
21033 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
21034 EMACS_INT, since callers assume the returned value fits in int.
21035 (upcase1): Likewise, for UPCASE_TABLE.
21036 (uppercasep, lowercasep, upcase): New static inline functions.
21037 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

21047 (regex_compile, re_match_2_internal): Mark locals as initialized.
21048 (RETALLOC_IF): Define only if needed.
21049 (WORDCHAR_P): Likewise. This one is never needed, but is used
21050 only in a comment talking about a compiler bug, so put inside
21051 the #if 0 of that comment.
21052 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
21053 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

21079 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
21080 New macros, so that the caller can use some names other than
21081 gcpro1, gcpro2, etc.
21082 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
21084 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
21085 argument, for consistency with GCPRO2_VAR, etc: it is now the
21086 prefix of the variable, not the variable itself. All uses
21088 * dired.c (directory_files_internal, file_name_completion):
21089 Rename locals to avoid shadowing.
21091 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
21092 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
21093 dired.c's scmp function, had undefined behavior.
21094 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21095 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
21096 * buffer.h: ... to here, because these macros use current_buffer,
21097 and the new implementation with inline functions needs to have
21098 current_buffer in scope now, rather than later when the macros
21100 (downcase, upcase1): New static inline functions.
21101 (DOWNCASE, UPCASE1): Reimplement using these functions.
21102 This avoids undefined behavior in expressions like
21103 DOWNCASE (x) == DOWNCASE (y), which previously suffered
21104 from race conditions in accessing the global variables
21105 case_temp1 and case_temp2.
21106 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
21107 * lisp.h (case_temp1, case_temp2): Remove their decls.
21108 * character.h (ASCII_CHAR_P): Move from here ...
21109 * lisp.h: ... to here, so that the inline functions mentioned
21110 above can use them.
21112 * dired.c (directory_files_internal_unwind): Now static.
21114 * fileio.c (file_name_as_directory, directory_file_name):
21115 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
21117 (file_name_as_directory): Use const pointers when appropriate.
21118 (Fexpand_file_name): Likewise. In particular, newdir might
21119 point at constant storage, so make it a const pointer.
21120 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
21121 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
21123 (Fset_file_times, Finsert_file_contents, auto_save_error):

21128 to avoid shadowing.
21130 * marker.c (bytepos_to_charpos): Remove; unused.
21132 * lisp.h (verify_bytepos, count_markers): New decls,
21133 so that gcc does not warn that these functions aren't declared.
21135 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
21136 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
21137 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
21138 (copy_text): Remove unused local var.
21140 * filelock.c (within_one_second): Now static.
21141 (lock_file_1): Rename local to avoid shadowing.
21143 * buffer.c (fix_overlays_before): Mark locals as initialized.
21144 (fix_start_end_in_overlays): Likewise. This function should be
21145 simplified by using pointers-to-pointers, but that's a different
21147 (switch_to_buffer_1): Now static.
21148 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
21149 (report_overlay_modification): Rename locals to avoid shadowing.
21151 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
21152 Fix pointer signedness issue.
21153 (sys_subshell): Mark local as volatile if checking for lint,
21154 to suppress a gcc -Wclobbered warning that does not seem to be right.
21155 (MAXPATHLEN): Define only if needed.
21157 * process.c (serial_open, serial_configure): Move decls from here ...
21158 * systty.h: ... to here, so that they can be checked.
21160 * fns.c (get_random, seed_random): Move extern decls from here ...
21161 * lisp.h: ... to here, so that they can be checked.
21163 * sysdep.c (reset_io): Now static.
21164 (wait_for_termination_signal): Remove; unused.
21166 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

21169 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
21170 (DENSE_TABLE_SIZE): Remove; unused.
21171 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
21172 (describe_map_tree):
21173 Rename locals to avoid shadowing.
21175 * keyboard.c: Declare functions static if they are not used elsewhere.

21323 1152921504606846976) returns the obviously-bogus value (-948597
21324 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
