3 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
4 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
5 for some of that bug's symptoms can now cause Emacs to abort.
7 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
8 The bug that caused SIGCHLD to get lost has been fixed, and the
9 workaround for it can now cause Emacs to abort.
11 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
13 * sysdep.c (emacs_abort): Bump backtrace size to 40.
14 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
15 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
17 2012-12-16 Romain Francoise <romain@orebokech.com>
19 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
20 (Fcopy_file): Change last arg to `preserve_extended_attributes'
21 and copy ACL entries of file in addition to SELinux context if

25 * Makefile.in (LIBACL_LIBS): New macro.
28 2012-12-15 Paul Eggert <eggert@cs.ucla.edu>
30 * fileio.c (internal_delete_file): Use bool for boolean.
32 2012-12-15 Eli Zaretskii <eliz@gnu.org>
34 Fix bug #13079 on MS-Windows with temp files not being deleted.
35 * w32.h (_child_process): New members input_file and
37 (register_child): First argument is now pid_t.
38 (record_infile, record_pending_deletion): New prototypes.
40 * w32proc.c (new_child): Initialize input_file and
41 pending_deletion members of the child.
42 (delete_child): Delete the child's temporary input file, if any,
43 that is pending deletion.
44 (register_child): First argument is now pid_t.
45 (record_infile, record_pending_deletion): New functions.
46 (reap_subprocess): Fix a typo in DebPrint string.
47 (sys_spawnve, sys_kill): Use pid_t for PID arguments.

50 if delete-file succeeds, zero otherwise.
52 * lisp.h (internal_delete_file): Adjust prototype.
54 * callproc.c (Fcall_process): Don't overwrite infile with result
56 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
57 asynchronous subprocess, record the name of the input file name,
59 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
60 delete the file, record it as pending deletion when the subprocess
63 2012-12-14 Eli Zaretskii <eliz@gnu.org>
65 * editfns.c [HAVE_PWD_H]: Include grp.h.

71 Fix permissions bugs with setgid directories etc. (Bug#13125)
72 * dired.c (Ffile_attributes): Return t as the 9th attribute,
73 to mark it as a placeholder. The old value was often wrong.

85 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
86 try to get accurate owner and group information from NT file
87 security APIs. This is to make most callers of 'stat' and
88 'lstat', which don't need that information, much faster.
90 * dired.c (Ffile_attributes) [WINDOWSNT]:
91 Set w32_stat_get_owner_group to a non-zero value, to request accurate
92 owner and group information from 'lstat'.
94 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
96 * fileio.c (Finsert_file_contents): Don't put tail into head area,
97 as that confuses set-auto-coding, so insist on the head-read
98 returning the full 1024 bytes. Let lseek compute the tail offset;
99 less work for us. Do not ignore I/O errors when reading the tail.
101 * xdisp.c: Minor style fixes.
102 (init_iterator): Hoist assignment out of if-expression.

123 files, fixing a regression from 24.2.
124 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
126 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
128 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
129 fstat shouldn't fail, and if it does fail copy-file should not proceed.
130 Remove unnecessary S_ISLNK test, as (contra the comments) this
131 function can't copy symlinks. Improve quality of error message
132 when attempting to copy files that are neither regular files nor
135 2012-12-12 Dmitry Antipov <dmantipov@yandex.ru>

143 2012-12-12 Daniel Colascione <dancol@dancol.org>
145 * unexcw.c (fixup_executable): use posix_fallocate to ensure that
146 the dumped Emacs is not a sparse file, greatly improving Cygwin
147 "make bootstrap" performance.

151 * inotify.c (inotify_callback): Generate an Emacs event for every
152 incoming inotify event.
154 2012-12-11 Eli Zaretskii <eliz@gnu.org>
156 * xdisp.c (handle_face_prop): Fix logic of computing
157 it->start_of_box_run_p.
158 (append_space_for_newline): If the glyph row is R2L, reset the
159 iterator's end_of_box_run_p flag before prepending the space glyph.
160 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
161 iterator's start_of_box_run_p flag before prepending the stretch.
162 (append_glyph, produce_image_glyph, append_composite_glyph)
163 (append_stretch_glyph, append_glyphless_glyph): Reverse the
164 left_box_line_p and right_box_line_p flags of the glyph for R2L
165 glyph rows. (Bug#13011)
167 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>

177 2012-12-11 Eli Zaretskii <eliz@gnu.org>
179 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
180 encoded_file_name, which is what it is.
182 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>

216 (hinst): Remove unneeded extern declaration.
217 (_start): Remove initialization of above variables; remove
218 initialization of hinst, as cache_system_info now does that.
220 * emacs.c (main): Call cache_system_info early in startup; we
221 previously weren't calling it in Cygwin builds.

248 2012-12-10 Eli Zaretskii <eliz@gnu.org>
250 Support for filesystem notifications on MS-Windows.
251 * w32proc.c (sys_select): If drain_message_queue returns non-zero,

475 * callproc.c, process.h (record_kill_process):
476 New function, containing part of the old call_process_kill.
477 (call_process_kill): Use it.
478 This does not change call_process_kill's behavior.
479 * process.c (Fdelete_process): Use record_kill_process to fix a
480 race condition that could cause Emacs to lose track of a child.
482 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
484 Avoid code duplication between prev_frame and next_frame.
485 * frame.c (candidate_frame): New function. Add comment.
486 (prev_frame, next_frame): Use it. Adjust comment.
488 2012-12-06 Eli Zaretskii <eliz@gnu.org>
490 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
491 fails, signal an error instead of continuing with an empty
493 Encode expanded temp file pattern before passing it to mkstemp or
496 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
497 Encode the file name before passing it to dostounix_filename, in
498 case it will downcase it (under w32-downcase-file-names).
501 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
503 Minor call-process cleanups.
504 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
505 at the same time as other platforms, to simplify analysis.
506 No need for fd0_volatile since we have synch_process_fd.
507 Avoid needless emacs_close; arg is always negative.

511 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
514 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
516 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
517 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
518 and mouse_face_hidden members to a bitfields.
519 * frame.h (struct frame): Remove set-but-not-used space_width member.
520 (FRAME_SPACE_WIDTH): Remove.
521 * nsterm.m, w32term.c, xterm.c: Adjust users.

527 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
529 Don't let call-process be a zombie factory (Bug#12980).
530 Fixing this bug required some cleanup of the signal-handling code.
531 As a side effect, this change also fixes a longstanding rare race
532 condition whereby Emacs could mistakenly kill unrelated processes,
533 and it fixes a bug where a second C-g does not kill a recalcitrant
534 synchronous process in GNU/Linux and similar platforms.
535 The patch should also fix the last vestiges of Bug#9488,
536 a bug which has mostly been fixed on the trunk by other changes.
537 * callproc.c, process.h (synch_process_alive, synch_process_death)
538 (synch_process_termsig, sync_process_retcode):
539 Remove. All uses removed, to simplify analysis and so that
540 less consing is done inside critical sections.
541 * callproc.c (call_process_exited): Remove. All uses replaced
542 with !synch_process_pid.
543 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
544 These take the role of what used to be in unwind-protect arg.
546 (block_child_signal, unblock_child_signal):
547 New functions, to avoid races that could kill innocent-victim processes.
548 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
549 (call_process_kill): Record killed processes as deleted, so that
550 zombies do not clutter up the system. Do this inside a critical
551 section, to avoid a race that would allow the clutter.
552 (call_process_cleanup): Fix code so that the second C-g works again
553 on common platforms such as GNU/Linux.
554 (Fcall_process): Create the child process in a critical section,
555 to fix a race condition. If creating an asynchronous process,
556 record it as deleted so that zombies do not clutter up the system.
557 Do unwind-protect for WINDOWSNT too, as that's simpler in the
558 light of these changes. Omit unnecessary call to emacs_close
559 before failure, as the unwind-protect code does that.
560 * callproc.c (call_process_cleanup):
561 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
562 * process.c (record_deleted_pid): New function, containing
563 code refactored out of Fdelete_process.
564 (Fdelete_process): Use it.
565 (process_status_retrieved): Remove. All callers changed to use
567 (record_child_status_change): Remove, folding its contents into ...
568 (handle_child_signal): ... this signal handler. Now, this
569 function is purely a handler for SIGCHLD, and is not called after
570 a synchronous waitpid returns; the synchronous code is moved to
571 wait_for_termination. There is no need to worry about reaping
572 more than one child now.
573 * sysdep.c (get_child_status, child_status_changed): New functions.
574 (wait_for_termination): Now takes int * status and bool
575 interruptible arguments, too. Do not record child status change;
576 that's now the caller's responsibility. All callers changed.
577 Reimplement in terms of get_child_status.
578 (wait_for_termination_1, interruptible_wait_for_termination):
579 Remove. All callers changed to use wait_for_termination.
580 * syswait.h: Include <stdbool.h>, for bool.
581 (record_child_status_change, interruptible_wait_for_termination):
583 (record_deleted_pid, child_status_changed): New decls.
584 (wait_for_termination): Adjust to API changes noted above.
586 * bytecode.c, lisp.h (Qbytecode): Remove.
587 No longer needed after 2012-11-20 interactive-p changes.
589 2012-12-03 Eli Zaretskii <eliz@gnu.org>
591 * xdisp.c (redisplay_window): If the cursor is visible, but inside
592 the scroll margin, move point outside the margin. (Bug#13055)
594 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
596 * gtkutil.c (my_log_handler): New function.

601 * lisp.h (modify_region): Rename to...
602 (modify_region_1): ...new prototype.
603 * textprop.c (modify_region): Now static. Adjust users.
604 * insdel.c (modify_region): Rename to...
605 (modify_region_1): ...new function to work with current buffer.
606 Adjust comment and users. Use true and false for booleans.
608 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
610 * alloc.c (free_save_value): New function.
611 (safe_alloca_unwind): Use it.
612 * lisp.h (free_save_value): New prototype.
613 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
615 (save_excursion_restore): Adjust to match saved data structure.
616 Use free_save_value to offload some work from GC. Drop obsolete
619 2012-12-03 Chong Yidong <cyd@gnu.org>
621 * fileio.c (Vauto_save_list_file_name): Doc fix.
623 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
625 * w32fns.c: Remove prototype of atof.
626 (syspage_mask): Declared DWORD_PTR, for compatibility with 64-bit
628 (file_dialog_callback): Declared UINT_PTR.
630 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
633 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
634 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
637 2012-12-03 Glenn Morris <rgm@gnu.org>
639 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
641 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
643 Fix xpalloc confusion after memory is exhausted.
644 * alloc.c (xpalloc): Comment fix.
645 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
646 and signals an error, do not clear charset_table_size, as
647 charset_table is still valid.
648 * doprnt.c (evxprintf): Clear *BUF after freeing it.
650 Use execve to avoid need to munge environ (Bug#13054).
651 * callproc.c (Fcall_process):
652 * process.c (create_process):
653 Don't save and restore environ; no longer needed.
654 * callproc.c (child_setup):
655 Use execve, not execvp, to preserve environ.
657 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
659 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
661 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
663 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
664 display for sliced images (Bug#10500).
666 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
668 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
670 * doc.c (Fdocumentation): Re-add handling of function-documentation,
671 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
673 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
675 * xdisp.c (window_outdated): Remove eassert since it hits
676 some suspicious corner cases (see Bug#13007 and Bug#13012).
677 (mode_line_update_needed): New function.
678 (redisplay_internal, redisplay_window): Use it.
679 (ensure_selected_frame): New function.
680 (redisplay_internal, unwind_redisplay): Use it.
681 (redisplay_internal): Move comment about buffer_shared...
682 (buffer_shared_and_changed): ...near to its real use.
684 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
686 * callproc.c (Fcall_process): Don't misreport vfork failure.
688 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
690 * callproc.c (Fcall_process): Fix vfork portability problems.
691 Do not assume that fd[0], count, filefd, and save_environ survive
692 vfork. Fix bug whereby wrong errno value could be reported for
693 pipe failure. Some minor cleanups, too, as follows. Move buf and
694 bufsize to the context where they're needed. Change new_argv to
695 be of type char **, as this is more convenient and avoids casts.
696 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
697 Now local constants, not macros.
699 2012-11-18 Kenichi Handa <handa@gnu.org>
701 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
702 for the variable "f".
704 2012-11-13 Kenichi Handa <handa@gnu.org>
706 * font.c (font_unparse_xlfd): Exclude special characters from the
707 generating XLFD name.

749 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
750 between bpos_covered and bpos_max. This fixes cursor display when
751 several display strings follow each other.
753 * .gdbinit (pgx): If the glyph's object is a string, display the
754 pointer to string data, rather than the value of the string object
755 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
757 * indent.c (Fvertical_motion): If the starting position is covered
758 by a display string, return to one position before that, to avoid
759 overshooting it inside move_it_to. (Bug#12930)
761 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
763 * frame.h (struct frame): Remove display_preempted member

780 of a literal "/". (Bug#12955)
781 (gl-stamp): Invoke fc.exe directly, not through cmd.

786 * dired.c: Assume HAVE_DIRENT_H.
787 (NAMLEN): Remove, replacing with ...
788 (dirent_namelen): New function. All uses changed. Use the GNU macro
789 _D_EXACT_NAMELEN if available, as it's faster than strlen.
790 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
791 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
792 * makefile.w32-in (DIR_H): Remove. All uses replaced with
794 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
795 * ndir.h: Rename to ../nt/inc/dirent.h.

802 * xftfont.c (xftfont_open): Remove duplicate assignment.
804 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
806 * alloc.c (Fgarbage_collect): Unblock input after clearing
807 gc_in_progress to avoid note_mouse_highlight glitch with GC.
808 * frame.h (FRAME_MOUSE_UPDATE): New macro.
809 * msdos.c (IT_frame_up_to_date): Use it here...
810 * w32term.c (w32_frame_up_to_date): ...here...
811 * xterm.c (XTframe_up_to_date): ...and here...
812 * nsterm.m (ns_frame_up_to_date): ...but not here.
813 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
815 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):

821 (update_menu_bar, update_tool_bar): Use it to
822 simplify large 'if' statements.
823 (redisplay_internal): Generalize commonly used
824 'tail' and 'frame' local variables.
826 2012-11-22 Eli Zaretskii <eliz@gnu.org>
828 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
829 with Windows system header.
831 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
833 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
834 * alloc.c: Assume unistd.h exists.
835 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
836 * sysdep.c (get_current_dir_name): Assume getcwd exists.

856 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
857 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
858 Define for the MSVC compiler.
860 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
862 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
863 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
864 dostounix_filename. Prevents crashes down the road, because
865 dostounix_filename assumes it gets a unibyte string.

911 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
913 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
915 2012-11-18 Eli Zaretskii <eliz@gnu.org>
917 * w32select.c: Include w32common.h before w32term.h, so that
918 windows.h gets included before w32term.h uses some of its
921 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
923 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:

944 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
945 ($(BLD)/sysdep.$(O)): Update dependencies.
947 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
949 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
950 * callproc.c (relocate_fd): Assume F_DUPFD.
951 * emacs.c, term.c (O_RDWR): Remove.
952 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
953 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
954 * nsterm.m: Assume <fcntl.h> exists.
955 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
956 (create_pty, Fmake_network_process, server_accept_connection)
957 (wait_reading_process_output, init_process_emacs):
959 (wait_reading_process_output): Put in a special case for WINDOWSNT
960 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
961 It's not clear this is needed, but it's a more-conservative change.
962 (create_process): Assume FD_CLOEXEC.
963 (create_process, create_pty): Assume O_NOCTTY.
964 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.

968 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
970 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
971 lack it, since gnulib guarantees this.
972 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
974 2012-11-17 Eli Zaretskii <eliz@gnu.org>
976 * w32.c (faccessat): Pretend that directories have the execute bit
977 set. Emacs expects that, e.g., in files.el:cd-absolute.
979 * w32proc.c (create_child): Don't clip the PID of the child
980 process to fit into an Emacs integer, as this is no longer a
982 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
983 reaping only the process specified by PID argument, if that is
984 positive. Use PID instead of dead_child to know which process to
985 reap. Wait for the child to die only if WNOHANG is not in
987 (sys_select): Don't set dead_child.
989 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
990 as it is no longer needed.
992 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
994 (record_child_status_change): Remove the setting of
995 record_at_most_one_child for the !WNOHANG case.
997 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
999 Fix problems in ns port found by static checking.
1000 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
1001 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
1002 not to process group.
1003 (ns_select): Use emacs_write, not write, as that's more robust
1004 in the presence of signals.
1005 (fd_handler:): Check for read errors.
1007 2012-11-16 Glenn Morris <rgm@gnu.org>
1009 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
1011 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
1013 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
1015 2012-11-16 Eli Zaretskii <eliz@gnu.org>
1017 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
1018 use the same value of thread handle.
1019 (start_timer_thread): If the timer thread exited (due to error),
1020 clean up by closing the two handles it used. Duplicate the caller
1021 thread's handle here, so it gets duplicated only once, when
1022 launching the timer thread. Set priority of the timer thread, not
1024 (getitimer): Don't duplicate the caller thread's handle here.
1027 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
1029 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
1032 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
1034 Remove no-longer-used pty_max_bytes variable.
1035 * process.c (pty_max_bytes): Remove; unused.
1036 (send_process): Do not set it.
1038 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
1040 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
1041 Update dependencies.
1043 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
1045 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
1046 This follows up on the 2012-09-29 patch that removed indirection
1047 for the 'function' field. Reported by Sergey Vinokurov in
1048 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
1050 2012-11-14 Eli Zaretskii <eliz@gnu.org>
1052 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
1053 different name, as the MS runtime does not have such a function,
1054 and probably never will.) All callers changed. Ignore DIRFD
1055 value if PATH is an absolute file name, to match Posix spec
1056 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
1059 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
1061 * xdisp.c (echo_area_display, redisplay_internal):
1062 Omit redundant check whether frame_garbaged is set.
1064 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
1066 Use faccessat, not access, when checking file permissions (Bug#12632).
1067 This fixes a bug that has been present in Emacs since its creation.
1068 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
1069 which must set some sort of record. (Torek's bug report was against
1070 a predecessor of GNU Emacs, but GNU Emacs happened to have the
1071 same common flaw.) See Torek's Usenet posting
1072 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
1073 Posted: Fri Apr 8 14:18:56 1983.
1074 * Makefile.in (LIB_EACCESS): New macro.
1076 * callproc.c (init_callproc):
1077 * charset.c (init_charset):
1078 * fileio.c (check_existing, check_executable, check_writable)
1080 * lread.c (openp, load_path_check):
1081 * process.c (allocate_pty):
1083 Use effective UID when checking permissions, not real UID.
1084 * callproc.c (init_callproc):
1085 * charset.c (init_charset):
1086 * lread.c (load_path_check, init_lread):
1087 Test whether directories are accessible, not merely whether they exist.
1088 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
1089 * fileio.c (check_existing, check_executable, check_writable)
1091 Use symbolic names instead of integers for the flags, as they're
1093 (check_writable): New arg AMODE. All uses changed.
1094 Set errno on failure.
1095 (Ffile_readable_p): Use faccessat, not stat + open + close.
1096 (Ffile_writable_p): No need to call check_existing + check_writable.
1097 Just call check_writable and then look at errno. This saves a syscall.
1098 dir should never be nil; replace an unnecessary runtime check
1099 with an eassert. When checking the parent directory of a nonexistent
1100 file, check that the directory is searchable as well as writable, as
1101 we can't create files in unsearchable directories.
1102 (file_directory_p): New function, which uses 'stat' on most platforms
1103 but faccessat with D_OK (for efficiency) if WINDOWSNT.
1104 (Ffile_directory_p, Fset_file_times): Use it.
1105 (file_accessible_directory_p): New function, which uses a single
1106 syscall for efficiency.
1107 (Ffile_accessible_directory_p): Use it.
1108 * xrdb.c (file_p): Use file_directory_p.
1109 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
1110 * lread.c (openp): When opening a file, use fstat rather than
1111 stat, as that avoids a permissions race. When not opening a file,
1112 use file_directory_p rather than stat.
1113 (dir_warning): First arg is now a usage string, not a format.
1114 Use errno. All uses changed.
1115 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
1116 that merely introduced a race.
1117 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
1118 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
1119 and similarly for the other O_* flags.
1120 * w32.c (sys_faccessat): Rename from sys_access and switch to
1121 faccessat's API. All uses changed.
1122 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
1123 (magic_db): Rename from magic_file_p.
1124 (magic_db, search_magic_path): Return an XrmDatabase rather than a
1125 char *, so that we don't have to test for file existence
1126 separately from opening the file for reading. This removes a race
1127 fixes a permission-checking problem, and simplifies the code.
1129 (file_p): Remove; no longer needed.
1131 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
1133 Omit glyphs initialization at startup.
1134 * dispnew.c (glyphs_initialized_initially_p): Remove.
1135 (adjust_frame_glyphs_initially): Likewise. Adjust users.
1136 (Fredraw_frame): Move actual code from here...
1137 (redraw_frame): ...to here. Add eassert. Adjust comment.
1138 (Fredraw_display): Use redraw_frame.
1139 * xdisp.c (clear_garbaged_frames): Likewise.
1141 2012-11-13 Eli Zaretskii <eliz@gnu.org>
1143 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
1144 passed to pint2str and pint2hrstr to be at most the size of the
1145 frame's decode_mode_spec_buffer. This avoids crashes with very
1146 large values of FIELD_WIDTH argument to decode_mode_spec.
1149 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
1151 Fix a race with verify-visited-file-modtime (Bug#12863).
1152 Since at least 1991 Emacs has ignored an mtime difference of no
1153 more than one second, but my guess is that this was to work around
1154 file system bugs that were fixed long ago. Since the race is
1155 causing problems now, let's remove that code.
1156 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
1157 whose time stamp is off by no more than a second. Insist that the
1158 file time stamps match exactly.
1160 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1162 * frame.h (struct frame): Convert external_tool_bar member to
1163 1-bit unsigned bitfield.
1164 * termhooks.h (struct terminal): Remove mouse_moved member since
1165 all users are long dead. Adjust comment on mouse_position_hook.
1167 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1169 Simplify by using FOR_EACH_FRAME here and there.
1170 * frame.c (next_frame, prev_frame, other_visible_frames)
1171 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
1172 * w32term.c (x_window_to_scroll_bar): Likewise.
1173 * window.c (window_list): Likewise.
1174 * xdisp.c (x_consider_frame_title): Likewise.
1175 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
1176 * xfns.c (x_window_to_frame, x_any_window_to_frame)
1177 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
1178 * xmenu.c (menubar_id_to_frame): Likewise.
1179 * xselect.c (frame_for_x_selection): Likewise.
1180 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
1181 (x_window_to_menu_bar): Likewise.
1182 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
1184 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
1186 * data.c (Qdefalias_fset_function): Now static.
1188 Another tweak to vectorlike_header change.
1189 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
1190 Remove, and replace all uses with ...
1191 (next_in_free_list, set_next_in_free_list):
1192 New functions, which respect C's aliasing rules better.
1194 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
1196 * window.c (list4i): Rename from 'quad'. All uses changed.
1197 Needed because <sys/types.h> defines 'quad' on Solaris 10.
1199 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
1201 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
1202 warning about mixing declarations and code in ISO C90.
1204 2012-11-10 Martin Rudalics <rudalics@gmx.at>
1206 * window.c (Fsplit_window_internal): Set combination limit of
1207 new parent window to t iff Vwindow_combination_limit is t;
1208 fixing a regression introduced with the change from 2012-09-22.
1209 (Fset_window_combination_limit): Fix doc-string.
1211 2012-11-10 Eli Zaretskii <eliz@gnu.org>
1213 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
1214 amount when the scroll margins are too large. When scrolling
1215 backwards in the buffer, give up if cannot reach point or the
1216 scroll margin within a reasonable number of screen lines.
1217 Fixes point position in window under scroll-up/down-aggressively when
1218 point is positioned many lines beyond the window top/bottom.
1221 * ralloc.c (relinquish): If real_morecore fails to return memory
1222 to the system, don't crash; instead, leave the last heap
1223 unchanged and return. (Bug#12774)
1225 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1227 * lisp.h (AUTOLOADP): New macro.
1228 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
1229 * data.c (Ffset): Remove special ad-advice-info handling.
1230 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
1232 (Finteractive_form): Simplify.
1233 (Fquo): Don't insist on having at least 2 arguments.
1234 (Qdefalias_fset_function): New var.
1236 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1238 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
1240 * nsfont.m (Qcondensed, Qexpanded): New variables.
1241 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
1242 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
1244 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1246 Fix recently introduced crash on MS-Windows (Bug#12839).
1247 * w32term.h (struct scroll_bar): Use convenient header.
1248 (SCROLL_BAR_VEC_SIZE): Remove.
1249 * w32term.c (x_scroll_bar_create): Use VECSIZE.
1251 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1253 Tweak last vectorlike_header change.
1254 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
1255 vectorlike object on the free list. This is introduced to avoid
1256 some (but not all) pointer casting and aliasing problems, see
1257 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
1258 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
1260 (xvectype, xvecsize): Use them to examine Lisp_Object values.
1262 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1264 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
1265 been removed, so remove them here also.
1267 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1269 * doc.c (Fdocumentation): Handle new property
1270 dynamic-docstring-function to replace the old ad-advice-info.
1272 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
1274 * fns.c (Qeql, hashtest_eq): Now static.
1276 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1278 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
1279 * fns.c (hashfn_eq, hashfn_eql, sxhash):
1280 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
1281 * buffer.c (compare_overlays): Use XLI rather than XHASH.
1283 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
1285 Use same hash function for hashfn_profiler as for hash_string etc.
1286 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
1287 * lisp.h (sxhash_combine): New inline function, with the contents
1288 of the old SXHASH_COMBINE.
1289 * profiler.c (hashfn_profiler): Use it, instead of having a
1290 special hash function containing a comparison that always yields 1.
1292 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1294 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
1295 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
1296 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
1299 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
1301 * image.c (xpm_make_color_table_h): Fix compiler error because
1302 make_hash_table changed.
1304 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
1306 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
1308 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1310 Use ad-hoc comparison function for the profiler's hash-tables.
1311 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
1312 (make_log): Use them.
1313 (handle_profiler_signal): Don't inhibit quit any longer since we don't
1314 call Fequal any more.
1315 (Ffunction_equal): New function.
1316 (cmpfn_profiler, hashfn_profiler): New functions.
1317 (syms_of_profiler): Initialize them.
1318 * lisp.h (struct hash_table_test): New struct.

1323 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
1324 (hash_lookup, hash_remove_from_table): Move assertion checking of
1325 hashfn result here. Check hash-equality before calling cmpfn.
1326 (Fmake_hash_table): Adjust call to make_hash_table.
1327 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.
1328 (syms_of_fns): Initialize them.

1332 * print.c (print_object): Adjust to new hash-table struct.
1333 * composite.c (composition_gstring_put_cache): Adjust to new hashfn.
1335 2012-11-08 Eli Zaretskii <eliz@gnu.org>
1337 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
1338 value of w32-scroll-lock-modifier is neither nil nor one of the
1339 known key modifiers. (Bug#12806)
1341 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
1343 Shrink struct vectorlike_header to the only size field.
1344 * lisp.h (enum pvec_type): Avoid explicit enum member values.
1346 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
1347 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
1348 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
1349 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
1350 information from the vector header. Adjust comment.
1351 (XSETPVECTYPE, XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR)
1352 (PSEUDOVECTOR_TYPEP, DEFUN): Adjust to match new vector header
1354 (XSETSUBR, SUBRP): Adjust to match new Lisp_Subr layout.
1355 (struct vectorlike_header): Remove next member. Adjust comment.

1357 (allocate_pseudovector): Adjust prototype.
1358 * alloc.c (mark_glyph_matrix, mark_face_cache, allocate_string)
1359 (sweep_string, lisp_malloc): Remove useless prototypes.
1360 (enum mem_type): Adjust comment.
1361 (NEXT_IN_FREE_LIST): New macro.
1362 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
1363 (Fmake_bool_vector): Likewise.
1364 (struct large_vector): New type to represent allocation unit for
1365 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
1366 (large_vectors): Change type to struct large_vector.
1367 (allocate_vector_from_block): Simplify.
1368 (PSEUDOVECTOR_NBYTES): Replace with...
1369 (vector_nbytes): ...new function. Adjust users.
1370 (sweep_vectors): Adjust processing of large vectors.
1371 (allocate_vectorlike): Likewise.
1372 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
1373 Add easserts. Adjust XSETPVECTYPESIZE usage.
1374 (allocate_buffer): Use BUFFER_PVEC_INIT.
1375 (live_vector_p): Adjust to match large vector.
1376 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
1377 * buffer.h (struct buffer): Add next member.
1378 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
1380 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
1381 * fns.c (internal_equal): Adjust to match enum pvec_type change.
1382 (copy_hash_table): Adjust to match vector header change.
1383 * lread.c (defsubr): Use XSETPVECTYPE.
1384 * .gdbinit (xpr, xbacktrace): Adjust to match vector header change.
1385 (xvectype): Likewise. Print PVEC_NORMAL_VECTOR for regular vectors.
1386 (xvecsize): New command.
1388 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
1390 * keyboard.c (event_to_kboard): Do not dereference
1391 frame_or_window field of SELECTION_REQUEST_EVENT
1392 and SELECTION_CLEAR_EVENT events (Bug#12814).
1393 * xterm.h (struct selection_input_event): Adjust comment.
1395 2012-11-07 Eli Zaretskii <eliz@gnu.org>
1397 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
1398 such as Scroll Lock, if the respective keys are treated as
1399 function keys, not as modifiers. This avoids destroying non-ASCII
1400 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
1402 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
1404 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
1406 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1408 Restore some duplicate definitions (Bug#12814).
1409 This undoes part of the 2012-11-03 changes. Some people build
1410 with plain -g rather than with -g3, and they need the duplicate
1411 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
1412 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
1413 Define as macros, as well as as enums or as constants.
1415 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
1417 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
1418 to keypad keys (Bug#12816).
1420 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1422 Minor adjustments of recently-changed frame functions.
1423 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
1424 known to be a frame (we're in the FRAMEP branch).
1425 * lisp.h (Qframep): Remove decl. frame.h declares this.
1426 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
1427 since they're meant for Lisp fixnum values.
1429 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1431 * window.c (Fwindow_combination_limit): Revert to the only
1432 required argument and adjust docstring as suggested in
1433 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
1434 by Martin Rudalics <rudalics@gmx.at>.
1436 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1438 Widely used frame validity and checking functions.
1439 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
1440 * frame.c (decode_live_frame, decode_any_frame): New functions.
1441 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
1442 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
1443 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
1444 (Fframe_pointer_visible_p): Use decode_any_frame.
1445 (Fmake_frame_visible, Fmake_frame_invisible, Ficonify_frame)

1448 (Fframe_focus): Likewise. Allow zero number of arguments.
1450 (frame_buffer_list, frame_buffer_predicate): Remove.
1451 * lisp.h (frame_buffer_predicate): Remove prototype.
1452 * buffer.c (Fother_buffer): Use decode_any_frame.
1453 * xdisp.c (Ftool_bar_lines_needed): Likewise.
1454 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
1455 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
1456 (Fclose_font, Ffont_info): Use decode_live_frame.
1457 * fontset.c (check_fontset_name): Likewise.
1458 * terminal.c (Fframe_terminal): Likewise.
1459 * w32fns.c (check_x_frame): Likewise.
1460 * window.c (Fminibuffer_window, Fwindow_at)
1461 (Fcurrent_window_configuration): Likewise.

1465 * xfaces.c (frame_or_selected_frame): Remove.
1466 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
1467 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
1468 (Fframe_face_alist): Use decode_live_frame.
1469 * xfns.c (check_x_frame): Likewise.
1471 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1473 * window.c (quad): New function.
1474 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
1475 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
1476 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
1477 (Fwindow_line_height): Use it.
1478 (Fwindow_fringes): Use list3.
1479 (Fwindow_scroll_bars): Use list4.
1480 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
1481 (Fwindow_combination_limit): Allow zero number of arguments.
1483 2012-11-05 Eli Zaretskii <eliz@gnu.org>
1485 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
1487 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
1488 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
1489 file descriptor 2 for standard error. (Bug#12805)
1491 2012-11-05 Chong Yidong <cyd@gnu.org>
1493 * process.c (wait_reading_process_output): Revert previous change.
1495 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
1497 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
1498 This removes code that has been obsolete since around 1990.
1499 * callproc.c (Fcall_process):
1501 * process.c (create_process):
1502 * term.c (dissociate_if_controlling_tty):
1503 Assume setsid exists.
1504 * callproc.c (child_setup): Assume setpgid exists and behaves as
1505 per POSIX.1-1988 or later.
1506 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
1507 * emacs.c (shut_down_emacs):
1508 * sysdep.c (sys_suspend, init_foreground_group):
1509 Assume getpgrp behaves as per POSIX.1-1998 or later.
1510 * msdos.c (setpgrp): Remove.
1511 (tcgetpgrp, setpgid, setsid): New functions.
1512 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
1513 * term.c (no_controlling_tty): Remove; unused.
1514 * w32proc.c (setpgrp): Remove.
1515 (setsid, tcgetpgrp): New functions.
1517 Simplify by assuming __fpending.
1518 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
1519 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
1520 Do not assume that __fpending's result fits in int.
1522 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
1524 Remove EMACS_OUTQSIZE+sleep hack.
1525 * dispnew.c (update_frame_1): Remove hack for terminals slower
1526 than 2400 bps, which throttled Emacs by having it sleep.
1527 This code hasn't worked since at least 2007, when the multi-tty stuff
1528 was added, and anyway those old terminals are long dead.
1529 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
1530 without the dispnew.c change, as dispnew.c doesn't include systty.h.
1532 Fix data-loss with --version (Bug#9574).
1533 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
1534 as we can't assume that emacs_strerror is initialized, and strerror
1535 is good enough here.
1536 (main): Invoke atexit earlier, to catch earlier instances of
1537 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
1539 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
1541 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
1542 (keyDown): Remap keypad keys to X11 virtual key codes.
1544 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
1546 Fix data-loss with --batch (Bug#9574).
1547 * emacs.c: Include <close-stream.h>.
1548 (close_output_streams): New function.
1549 (main): Pass it to atexit, so that Emacs closes stdout and stderr
1550 and handles errors appropriately.
1551 (Fkill_emacs): Don't worry about flushing, as close_output_stream
1554 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
1555 The symptom is a diagnostic "GLib-WARNING **: In call to
1556 g_spawn_sync(), exit status of a child process was requested but
1557 SIGCHLD action was set to SIG_IGN and ECHILD was received by
1558 waitpid(), so exit status can't be returned." The diagnostic
1559 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
1560 The real bug is a race condition between Emacs and glib: Emacs
1561 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
1562 so that glib can't find it. Work around the bug by invoking
1563 waitpid only on subprocesses that Emacs itself creates.
1564 * process.c (create_process, record_child_status_change):
1565 Don't use special value -1 in pid field, as the caller now must
1566 know the pid rather than having the callee infer it.
1567 The inference was sometimes incorrect anyway, due to another race.
1568 (create_process): Set new 'alive' member if child is created.
1569 (process_status_retrieved): New function.
1570 (record_child_status_change): Use it.
1571 Accept negative 1st argument, which means to wait for the
1572 processes that Emacs already knows about. Move special-case code
1573 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
1574 processes that have already been waited for, by testing and
1575 clearing new 'alive' member.
1576 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
1577 now does this internally.
1578 (handle_child_signal): Let record_child_status_change do all
1579 the work, since we do not want to reap all exited child processes,
1580 only the child processes that Emacs itself created.
1581 * process.h (Lisp_Process): New boolean member 'alive'.
1583 Omit duplicate definitions no longer needed with gcc -g3.
1584 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
1585 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
1586 Define only as macros. There's no longer any need to also define
1587 these symbols as enums or as constants, since we now assume
1588 gcc -g3 when debugging.
1590 2012-11-03 Eli Zaretskii <eliz@gnu.org>
1592 * lisp.mk: Adjust comments to the fact that term/internal is now
1593 loaded from loadup.el.
1595 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
1596 (msdos_fatal_signal): New function.
1597 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
1600 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
1601 for GCC versions before 4.
1602 (emacs_raise): Define to call msdos_fatal_signal.
1604 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
1605 iterator when starting in the middle of a display or overlay
1608 2012-11-03 Chong Yidong <cyd@gnu.org>
1610 * process.c (wait_reading_process_output): Clean up the last
1613 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
1615 * process.c (wait_reading_process_output): Avoid a race condition
1616 with SIGIO delivery (Bug#11536).
1618 2012-11-03 Chong Yidong <cyd@gnu.org>
1620 * buffer.c (cursor_type): Untabify docstring.
1622 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1624 * frame.h (struct frame): Drop can_have_scroll_bars member
1625 which is meaningless for a long time. Adjust comments.
1626 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
1627 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
1629 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1631 * window.c (decode_next_window_args): Update window arg after
1632 calling decode_live_window and so fix crash reported at
1633 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
1634 by Juanma Barranquero <lekktu@gmail.com>.
1635 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
1636 * font.c (Ffont_at): Likewise.
1638 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
1640 * widget.c (resize_cb): New function.
1641 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
1642 (EmacsFrameResize): Check if all is up to date before changing frame
1645 2012-11-02 Eli Zaretskii <eliz@gnu.org>
1647 Implement backtrace output for fatal errors on MS-Windows.
1648 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
1649 (BACKTRACE_LIMIT_MAX): New macro.
1650 (w32_backtrace): New function.
1651 (emacs_abort): Use w32_backtrace when the user chooses not to
1652 attach a debugger. Update the text of the abort dialog.
1654 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1656 Window-related stuff cleanup here and there.
1657 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
1658 Use decode_any_window.
1659 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
1660 * xdisp.c (Fformat_mode_line): Likewise.
1661 * font.c (Ffont_at): Use decode_live_window.
1662 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
1663 * window.c (decode_next_window_args): Likewise.
1664 (decode_any_window): Remove static.
1665 * window.h (decode_any_window): Add prototype.
1666 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
1667 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
1670 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1672 Remove pad from struct input_event.
1673 * termhooks.h (struct input_event): Remove padding field.
1675 * keyboard.c (event_to_kboard): Simplify because frame_or_window
1676 member is never cons for a long time. Adjust comment.
1677 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
1678 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
1679 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
1680 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
1682 2012-11-01 Eli Zaretskii <eliz@gnu.org>
1684 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
1686 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
1688 Fix crash when using Emacs as commit editor for git (Bug#12697).
1689 * callproc.c (setpgrp): Remove macro, as we now use setpgid
1690 and it is configured in conf_post.h.
1691 (Fcall_process): Don't invoke both setsid and setpgid; the former
1692 is enough, if it exists.
1693 * callproc.c (Fcall_process, child_setup):
1694 * process.c (create_process): Use setpgid.
1695 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
1697 * dispnew.c (init_display): Initialize the foreground group
1698 if we are running a tty display.
1699 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
1700 * lisp.h (init_foreground_group): New decl.
1701 * sysdep.c (inherited_pgroup): New static var.
1702 (init_foreground_group, tcsetpgrp_without_stopping)
1703 (narrow_foreground_group, widen_foreground_group): New functions.
1704 (init_sys_modes): Narrow foreground group.
1705 (reset_sys_modes): Widen foreground group.
1707 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
1709 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
1711 2012-10-31 Martin Rudalics <rudalics@gmx.at>
1713 * minibuf.c (read_minibuf): Restore current buffer since
1714 choose_minibuf_frame calling Fset_frame_selected_window may
1715 change it (Bug#12766).
1717 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
1719 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
1721 2012-10-30 Kenichi Handa <handa@gnu.org>
1723 * font.c (Ffont_at): If WINDOW is specified and it is not
1724 displaying the current buffer, signal an error.
1726 2012-10-29 Daniel Colascione <dancol@dancol.org>
1728 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
1729 In preparation for fixing bug#12739, move these functions from
1732 * coding.h, coding.c: ... to here, and compile them only when
1733 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
1734 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
1736 2012-10-28 Eli Zaretskii <eliz@gnu.org>
1738 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
1739 (timer_loop, getitimer, setitimer): Use it instead of
1740 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
1742 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
1745 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
1747 * nsterm.m (NO_APPDEFINED_DATA): New define.
1748 (last_appdefined_event_data): New variable
1749 (last_appdefined_event): Remove.
1750 (ns_select): Initialize t from last_appdefined_event_data instead
1751 of [last_appdefined_event data1].
1752 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
1753 remove last_appdefined_event (Bug#12698).
1755 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
1757 * frame.c (x_set_font): Catch internal error.
1759 2012-10-27 Eli Zaretskii <eliz@gnu.org>
1761 Avoid overflow in w32 implementation of interval timers.
1762 When possible, for ITIMER_PROF count only times the main thread
1764 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
1765 'volatile ULONGLONG' types. All the other data which was
1766 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
1767 (GetThreadTimes_Proc): New typedef.
1768 (w32_get_timer_time): New function, returns a suitable time value
1770 (timer_loop): Enter critical section when accessing ULONGLONG
1771 values of the itimer_data struct, as these accesses are no longer
1772 atomic. Call 'w32_get_timer_time' instead of 'clock'.
1773 Remove unused variable.
1774 (init_timers): Initialize s_pfn_Get_Thread_Times.
1775 (start_timer_thread): Don't assign itimer->caller_thread here.
1776 (getitimer): Assign itimer->caller_thread here.
1777 (setitimer): Always call getitimer to get the value of ticks_now.
1778 (sys_spawnve): Avoid compiler warning about format mismatch.
1780 2012-10-26 Eli Zaretskii <eliz@gnu.org>
1782 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
1783 mouse movement events if the menu bar is active. This avoids
1784 producing a busy "hour-glass" cursor by Windows if the mouse
1785 pointer is positioned over a tooltip shown for some menu item.
1787 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
1789 Don't assume process IDs fit in int.
1790 * emacs.c (shut_down_emacs) [!DOS_NT]:
1791 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
1792 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
1793 Use pid_t, not int, to store process IDs, as 'int'
1794 is not wide enough on a few platforms (e.g., AIX and IRIX).
1796 2012-10-23 Kenichi Handa <handa@gnu.org>
1798 The following change is to make face-font-rescale-alist work
1799 correctly for non-ASCII fonts.
1801 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
1802 (font_open_for_lface): Handle Vface_font_rescale_alist.
1804 2012-10-23 Chong Yidong <cyd@gnu.org>
1806 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
1808 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
1810 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
1812 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
1814 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
1817 2012-10-21 Glenn Morris <rgm@gnu.org>
1819 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
1821 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
1823 Port to OpenBSD 5.1.
1824 * frame.c (Fmouse_position, Fmouse_pixel_position):
1825 * xdisp.c (produce_stretch_glyph):
1826 Declare local vars only when they're needed.
1827 This is clearer and avoids a warning on OpenBSD about unused vars.
1828 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
1829 This is safer, and avoids OpenBSD warnings about unused vars.
1830 * keyboard.c (record_menu_key): Remove unnecessary decl.
1831 (poll_timer): Define only if POLL_FOR_INPUT is defined.
1832 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
1833 as our definition clashes with OpenBSD's.
1834 * xfaces.c (load_face_colors, check_lface_attrs)
1835 (get_lface_attributes_no_remap, get_lface_attributes)
1836 (lface_fully_specified_p, x_supports_face_attributes_p)
1837 (tty_supports_face_attributes_p, face_fontset, realize_face)
1838 (realize_x_face, realize_tty_face):
1839 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
1840 merely Lisp_Object *. This is more informative and avoids
1841 a warning on OpenBSD about accessing beyond an object's size.
1843 2012-10-20 Chong Yidong <cyd@gnu.org>
1845 * lread.c (Fload): Doc fix (Bug#12592).
1847 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
1849 * font.c (Ffont_at): Fix previous change.
1851 2012-10-19 Eli Zaretskii <eliz@gnu.org>
1853 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
1854 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
1857 * alloc.c (NSTATICS): Decrease to 0x800.
1859 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>
1861 * fns.c (Fnreverse): Include the problem element when signaling an
1864 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
1866 * nsterm.m (ns_select): Check writefds before call to
1867 FD_ISSET (Bug#12668).
1869 2012-10-18 Daniel Colascione <dancol@dancol.org>
1871 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
1872 (staticpro): If we run out of staticpro slots, die with an
1873 informative error instead of just calling emacs_abort.
1875 2012-10-18 Martin Rudalics <rudalics@gmx.at>
1877 Fix two flaws reported by Dmitry Antipov.
1878 * window.c (Ftemp_output_buffer_show): Remove.

2134 (get_input_pending): Remove first argument, since it was always
2135 the same pointer-to-int (now pointer-to-boolean) &input_pending,
2136 and behave as if it had that value. Return new value of
2137 input_pending. All callers changed.
2138 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
2139 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's

2182 match what GetLastError returns. Explain why the function is
2185 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
2186 'is_tooltip_frame', to avoid confusion with its global namesake.
2188 2012-10-08 Daniel Colascione <dancol@dancol.org>
2190 * xdisp.c (start_hourglass): Call w32_note_current_window when
2191 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
2192 build that caused Emacs to display the hourglass cursor forever.
2194 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
2195 which is broken under remote desktop, calculate the number of
2196 colors available for a display based on the display's number of
2197 planes and number of bits per pixel per plane. (bug#10397).
2199 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
2201 * nsfont.m (Vfonts_in_cache): New variable.
2202 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
2203 are used. Add cached fonts to Vfonts_in_cache.
2204 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
2206 2012-10-08 Juanma Barranquero <lekktu@gmail.com>

2230 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now

2234 2012-10-08 Daniel Colascione <dancol@dancol.org>
2236 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
2237 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
2238 accidental message numbering hole. Change other messages to

2258 * w32fns.c: Include w32common.h; include w32heap.h only in
2261 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
2262 Use `report_file_error' instead of `error' in order to better
2263 inform users of what went wrong. Increase NTGUI_UNICODE file
2264 dialog box file name length to 32k, the maximum allowed by the NT
2267 * w32common.h: New file.
2268 (ROUND_UP, ROUND_DOWN, get_page_size)

2272 (OS_NT, os_subtype, cache_system_info): Move here.
2274 * unexw32.c, unexcw.c: Include w32common.h.
2276 * emacs.c (main): Use (defined (WINDOWSNT) || defined
2277 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
2278 to call syms_of_w32select.
2280 * cygw32.h: Remove obsolete EXFUN declarations.
2282 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.

2296 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
2299 2012-10-08 Daniel Colascione <dancol@dancol.org>
2301 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
2302 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,

2306 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
2307 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
2308 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
2309 now a supported configuration.
2311 * Makefile.in: consolidate image variables into LIBIMAGE; add
2312 W32_OBJ and W32_LIBS. Compile new files.
2315 (_DebPrint) declare tracing facility for W32 debugging. We need
2316 to unify tracing later.
2318 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
2319 unconditional use of W32 Unicode functions. Cygwin runs only on
2320 100% Unicode operating systems.
2322 * cygw32.c: New file. Define Cygwin-specific facilities.
2323 (Fcygwin_convert_path_to_windows)
2324 (Fcygwin_convert_path_from_windows): New user functions for
2325 accessing Cygwin path-munging routines.
2327 * cygw32.h: New file.
2328 (WCSDATA, to_unicode, from_unicode): Define facilities for storing

2332 (w32_strerror): Just what it says on the tin.
2334 * emacs.c: Make the NS fork-then-exec code for daemon-launching
2335 also run for Cygwin; both systems have the same problem with using
2336 GUI facilities in a forked child. Also call syms_of_cygw32,
2337 syms_of_w32select in correct places.
2339 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
2340 needs fork-then-exec for daemon launching.
2342 * font.h: Include frame.h.
2344 * image.c: Use the image library cache machinery only when we're
2345 compiling for native WINDOWSNT; Cygwin can use shared libraries
2346 like any other Unixlike system.
2348 * keyboard.c: Clarify a comment regarding the input loop.
2350 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
2351 functions directly instead of trying to detect at runtime that our
2352 host operating system supports them. We make this change for two
2353 reasons: Cygwin lacks support for the multibyte character
2354 conversion functions used by the legacy menu code, and Cygwin
2355 never needs to rely on non-Unicode APIs.
2357 * unexw32.c (hinst): Declare extern.
2359 * w32.c: Change header order;
2360 (w32_strerror): Move to w32fns.c because we need it for
2361 non-WINDOWSNT builds.
2363 * w32.h: Add #error macro to make sure we don't include w32.h for
2364 Cygwin builds. Remove w32select declarations.
2366 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
2367 w32fns.c. w32console.c is WINDOWSNT-only.
2369 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
2370 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
2372 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
2373 (w32_major_version, w32_minor_version, w32_build_number)
2374 (os_subtype, sound_type): Define here
2375 (w32_defined_color): Make color parameter const for consistency
2376 with other _defined_color functions.
2377 (w32_createwindow): Unconditionally call w32_init_class instead of
2378 doing so only when hprevinst is non-NULL. Plumbing hprevinst
2379 through the code is complex and unnecessary because class
2380 registration is practically free.
2381 (w32_name_of_message): New EMACSDEBUG-only function.
2382 (Fset_message_beep): Move here
2383 (Fx_open_connection): Require that the display name for Windows be
2384 "w32" for consistency, emacsclient disambiguation, and maybe, one
2385 day, multi-window-system support.
2386 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
2387 Cygwin files for W32 GUI facilities, since these clearly don't
2388 expect Cygwin names.
2389 (_DebPrint): Define.
2390 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
2391 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
2392 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
2393 (w32_last_error): Remove.
2395 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
2397 * w32heap.c (syspage_mask): Declare here.
2398 (cache_system_info): Remove.
2400 * w32inevt.c (faked_key): Define globally, not statically.
2401 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
2402 (w32_console_toggle_lock_key): Move to w32fns.c.
2404 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
2406 * w32proc.c (_DebPrint): Move to w32fns.c.
2407 * w32select.c: Include string.h, stdio.h for Cygwin.
2408 * w32select.h: New File.
2410 * w32term.c: Include io.h for non-CYGWIN builds; needed for
2412 (w32_message_fd): New variable. Under Cygwin, holds the file
2413 descriptor the system used to tell us about pending thread
2416 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
2417 that prevented compilation under non-WINDOWSNT systems.
2419 (w32_initialize): Open /dev/windows and assign it to
2420 w32_message_fd. Provide w32 feature.
2422 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
2423 (WM_EMACS_INPUT_READY): add.
2424 (prepend_msg, w32_message_fd): Declare globally.
2427 (keyboard_handle): Use only when WINDOWSNT.
2428 (notify_msg_ready): New function. Posts a message to the main
2429 thread's message queue under CYGWIN, which wakes up the main
2430 thread from select(2) by making the /dev/windows file descriptor
2431 ready. Under WINDOWSNT, it sets an event the same way the old
2434 (post, prepend_msg): Actually call notify_msg_ready instead of
2435 setting the input event directly.
2437 2012-10-07 Eli Zaretskii <eliz@gnu.org>
2439 * ralloc.c (relinquish): If a heap is ready to be relinquished,
2440 but it still has blocs in it, don't return it to the system,
2441 instead of aborting. (Bug#12402)
2443 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
2445 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
2447 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
2448 MAC_OS_X_VERSION_10_6.
2449 (syms_of_nsterm): Remove comment about Panther and above for
2451 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
2452 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
2453 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
2455 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
2456 MAC_OS_X_VERSION_10_4.
2458 * nsmenu.m (fillWithWidgetValue:): Remove code for <
2459 MAC_OS_X_VERSION_10_2.
2461 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
2463 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
2464 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
2466 * nsterm.m (ns_in_resize): Remove (Bug#12479).
2467 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
2468 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
2469 Remove ns_in_resize check.
2470 (ns_clear_frame_area): Remove resize handle code.
2472 * nsfns.m (ns_in_resize): Remove.
2473 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
2474 Remove ns_in_resize check.
2476 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
2478 Improve sys_siglist detection.
2479 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
2480 defined as a macro, as is done in Solaris.
2481 (sys_siglist_entries): New macro.
2482 (save_strsignal): Use it.
2483 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
2484 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
2486 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
2488 * nsfns.m (Fx_create_frame): Call x_default_parameter with
2489 fullscreen/Fullscreen.
2491 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
2492 tobar_height is new.
2494 * nsterm.m (x_make_frame_visible): Check for fullscreen.
2495 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
2496 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
2497 (windowDidResize:): Check for correct window if old style fullscreen.
2498 Capitalize word in comment. Remove incorrect comment.
2499 (initFrameFromEmacs:): tbar_height renamed tibar_height.
2500 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
2501 error in drawing background.
2502 (toggleFullScreen:): Remove comment. Rearrange calls.
2503 Set toolbar values to zero, save old height in tobar_height.
2504 Restore tool bar height when leaving fullscreen.
2505 (canBecomeMainWindow): New function.
2507 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
2509 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
2511 2012-10-05 Eli Zaretskii <eliz@gnu.org>
2513 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
2515 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
2516 that time stamps of directories could also be changed.
2517 Don't request the too broad GENERIC_WRITE, only the more restrictive
2518 FILE_WRITE_ATTRIBUTES access rights.
2520 * fileio.c (Fset_file_times): Special-case ignoring errors for
2521 directories only on MSDOS, not on MS-Windows.
2523 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
2525 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
2527 2012-10-04 Eli Zaretskii <eliz@gnu.org>
2529 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
2530 see whether CreateFile failed.
2532 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
2534 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
2535 to avoid similar races.
2536 * keyboard.c (pending_signals): Now bool, not int.
2538 Port timers to OpenBSD, plus check for timer failures.
2539 OpenBSD problem reported by Han Boetes.
2540 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
2542 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
2543 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
2544 like OpenBSD, which has timer_settime but does not declare it.
2545 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
2546 whether to use itimerspec-related primitives. All uses of
2547 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
2549 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2551 * profiler.c (handle_profiler_signal): Fix a malloc race
2552 that caused Emacs to hang on Fedora 17 when profiling Lisp.
2554 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
2556 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
2558 2012-10-02 Eli Zaretskii <eliz@gnu.org>
2560 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
2561 consistent with the change in return value of 'safe_strsignal'.
2563 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2565 Prefer plain 'static' to 'static inline' (Bug#12541).
2566 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
2567 (bidi_set_sor_type, bidi_push_embedding_level)
2568 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
2569 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)

2573 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
2574 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
2575 Now 'static', not 'static inline'.
2577 Count overruns when profiling; change units to ns.
2578 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
2579 Give extra weight to samples after overruns, to attempt to count
2580 the time more accurately.
2581 (setup_cpu_timer): Change sampling interval units from ms to ns, since
2582 the underlying primitives nominally do ns.
2583 (Fprofiler_cpu_start): Document the change. Mention that
2584 the sampling intervals are only approximate.
2586 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
2588 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
2590 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
2591 case for the special 0 coding-system.
2593 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
2594 (Fmake_overlay): Remove redundant tests.
2595 (fix_start_end_in_overlays): Remove redundant recentering.
2597 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
2599 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
2600 Update dependencies.
2602 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2604 Fix a malloc race condition involving strsignal.
2605 A signal can arrive in the middle of a malloc, and Emacs's signal
2606 handler can invoke strsignal, which can invoke malloc, which is
2607 not portable. This race condition bug makes Emacs hang on GNU/Linux.
2608 Fix it by altering the signal handler so that it does not invoke
2610 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
2611 * process.c (status_message): Use const pointer, in case strsignal
2612 is #defined to safe_strsignal.
2613 * sysdep.c (sys_siglist, init_signals): Always define and
2614 initialize a substitute sys_siglist if the system does not define
2615 one, even if HAVE_STRSIGNAL.
2616 (safe_strsignal): Rename from strsignal. Always define,
2617 using sys_siglist. Return a const pointer.
2618 * syssignal.h (safe_strsignal): New decl.
2619 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
2621 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2623 * w32proc.c (timer_loop): Fix code that waits for timer
2624 expiration, to avoid high CPU usage.
2626 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
2628 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
2629 (sweep_weak_table): Remove redundant prototypes.
2631 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
2633 * emacs.c: Move the inclusion of TERM_HEADER after including
2634 windows.h on WINDOWSNT. This avoids compilation problems with
2637 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2639 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
2640 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
2641 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
2642 as the previous version used 'void *'.
2644 * ralloc.c (ROUNDUP): Fix last change.
2645 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
2648 * w32proc.c <disable_itimers>: New static flag.
2649 (init_timers): Initialize it to zero, after creating the critical
2650 sections used by the timer threads.
2651 (term_timers): Set to 1 before deleting the critical sections.
2652 (getitimer, setitimer): If disable_itimers is non-zero, return an
2653 error indication without doing anything. Reported by Fabrice
2654 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
2655 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
2657 [!HAVE_SETITIMER]: Behave as the previous version that didn't
2660 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
2661 term_ntproc after all the other bookkeeping, to get timers working
2662 as long as possible.
2664 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2666 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
2667 Suggested by Juri Linkov in
2668 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
2670 Prefer plain 'static' to 'static inline' (Bug#12541).
2671 With static functions, modern compilers inline pretty well by
2672 themselves; advice from programmers often hurts as much as it helps.
2673 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
2674 this change shrinks the text size of the Emacs executable by 1.1%
2675 without affecting CPU significantly in my benchmark.
2676 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)
2677 (live_float_p, live_misc_p, live_vector_p, live_buffer_p)

2751 (x_set_glyph_string_clipping, x_clear_glyph_string_rect):
2752 Now 'static', not 'static inline'.
2755 (bidi_copy_it): Do the whole copy with a single memcpy.
2756 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
2758 Revert the FOLLOW-SYMLINKS change for file-attributes.
2759 Doing it right would require several changes to Tramp, and there's
2760 not enough time to get that tested before the freeze today.
2761 * dired.c (directory_files_internal, Ffile_attributes):
2764 * frame.c (x_report_frame_params): Port better to wider ints.
2765 Do not assume that EMACS_UINT is the same width as uprintmax_t,
2766 or that pointers can be printed in 15 decimal digits.
2767 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

2791 (allocate_heap) [_WIN64]: Reserve 32GB of memory.
2792 (sbrk): Argument is now of type ptrdiff_t.
2794 * w32fns.c (HMONITOR): Condition declaration on _WIN32_WINNT being

2969 (handle_profiler_signal): Rename from sigprof_handler_1,
2970 for consistency with other handlers. Do not check whether
2971 cpu_log is a hash-table if garbage collecting, since it

2974 for consistency with other handlers.
2975 (setup_cpu_timer): New function, with much of what used to be in

2977 Prefer timer_settime if available, and prefer
2978 thread cputime clocks, then process cputime clocks, then
2979 monotonic clocks, to the old realtime clock. Use make_timeval
2980 to round more-correctly when falling back to setitimer.
2981 (Fprofiler_cpu_start): Use it.
2982 (Fprofiler_cpu_stop): Prefer timer_settime if available.

3252 2012-09-23 Eli Zaretskii <eliz@gnu.org>
3254 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
3255 fatal_error_backtrace.
3257 * w32proc.c (sys_kill): Undo last change: don't do anything when
3258 invoked to deliver SIGABRT to our own process. This is now
3259 handled by emacs_raise.
3261 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
3263 * w32term.c (w32_read_socket): Remove leftover reference to
3264 interrupt_input_pending.
3266 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3268 Do not use SA_NODEFER.
3269 Problem reported by Dani Moncayo in
3270 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
3272 * sysdep.c (emacs_abort): Do not reset signal handler.
3273 * emacs.c (terminate_due_to_signal): Reset signal handler here.
3274 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
3275 wanted even on POSIXish hosts, and it doesn't work on Windows.
3277 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3279 * xterm.c (x_term_init): Call fixup_locale before and after calling
3280 gtk_init (Bug#12392).
3282 2012-09-23 Chong Yidong <cyd@gnu.org>
3284 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
3285 Vdynamic_library_alist.
3287 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
3288 (Fgnutls_available_p): Caller changed.
3290 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
3291 (Flibxml_parse_xml_region): Likewise.
3293 * dispextern.h (struct image_type): Remove arg from init function.
3295 * image.c (Finit_image_library, lookup_image_type)
3296 (define_image_type): Remove now-unneeded second arg.
3297 (init_xpm_functions, init_png_functions, init_jpeg_functions)
3298 (init_tiff_functions, init_gif_functions, init_svg_functions):
3299 Arglist and w32_delayed_load calling convention changed.
3300 (gs_type): Remove init_gs_functions; there is no such function.
3301 (valid_image_p, make_image): Fix caller to lookup_image_type.
3303 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3305 Simplify and avoid signal-handling races (Bug#12471).
3307 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
3308 Avoid recursive loop if there's a fatal error in the function itself.
3309 * atimer.c (pending_atimers):
3310 * blockinput.h: Don't include "atimer.h"; no longer needed.
3311 (interrupt_input_pending): Remove. All uses removed.
3312 pending_signals now counts both atimers and ordinary interrupts.
3313 This is less racy than having three separate pending-signal flags.
3314 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
3316 Rename from their upper-case counterparts BLOCK_INPUT,
3317 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
3318 INPUT_BLOCKED_P, and turn into functions. All uses changed.
3319 This makes it easier to access volatile variables more accurately.
3320 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
3321 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
3322 that's more reliable if the code is buggy and sets
3323 interrupt_input_blocked to a negative value. All uses changed.
3324 * atimer.c (deliver_alarm_signal):
3325 Remove. No need to deliver this to the parent; any thread can
3326 handle this signal now. All uses replaced by underlying handler.
3327 * atimer.c (turn_on_atimers):
3328 * dispnew.c (handle_window_change_signal):
3329 * emacs.c (handle_danger_signal):
3330 * keyboard.c (kbd_buffer_get_event):
3331 Don't reestablish signal handler; not needed with sigaction.
3332 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
3334 Rework to avoid unnecessary accesses to volatile variables.
3335 (UNBLOCK_INPUT_TO): Now a function.
3336 (totally_unblock_input, unblock_input): New decls.
3337 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
3338 (init_data): Remove. Necessary stuff now done in init_signal.
3339 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
3340 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
3341 (fatal_error_code): Remove; no longer needed.
3342 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
3343 it doesn't always backtrace. All uses changed. No need to reset
3344 signal to default, since sigaction and/or die does that for us now.
3345 Use emacs_raise (FOO), not kill (getpid (), FOO).
3346 (main): Check more-accurately whether we're dumping.
3347 Move fatal-error setup to sysdep.c
3348 * floatfns.c: Do not include "syssignal.h"; no longer needed.
3349 * gtkutil.c (xg_get_file_name, xg_get_font):
3350 Remove no-longer-needed signal-mask manipulation.
3351 * keyboard.c, process.c (POLL_FOR_INPUT):
3352 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
3353 * keyboard.c (read_avail_input): Remove.
3354 All uses replaced by gobble_input.
3355 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
3356 (kbd_buffer_store_event_hold, gobble_input):
3357 (record_asynch_buffer_change) [USABLE_SIGIO]:
3358 (store_user_signal_events):
3359 No need to mess with signal mask.
3360 (gobble_input): If blocking input and there are terminals, simply
3361 set pending_signals to 1 and return. All hooks changed to not
3362 worry about whether input is blocked.
3363 (process_pending_signals): Clear pending_signals before processing
3364 them, in case a signal comes in while we're processing.
3365 By convention callers now test pending_signals before calling us.
3366 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
3367 New functions, to support changes to blockinput.h.
3368 (handle_input_available_signal): Now extern.
3369 (reinvoke_input_signal): Remove. All uses replaced by
3371 (quit_count): Now volatile, since a signal handler uses it.
3372 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
3373 All callers changed. Block SIGINT only if not already blocked.
3374 Clear sigmask reliably, even if Fsignal returns, which it can.
3375 Omit unnecessary accesses to volatile var.
3376 (quit_throw_to_read_char): No need to restore sigmask.
3377 * keyboard.c (gobble_input, handle_user_signal):
3378 * process.c (wait_reading_process_output):
3379 Call signal-handling code rather than killing ourselves.
3380 * lisp.h: Include <float.h>, for...
3381 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
3382 (pending_signals): Now volatile.
3383 (syms_of_data): Now const if IEEE floating point.
3384 (handle_input_available_signal) [USABLE_SIGIO]:
3385 (terminate_due_to_signal, record_child_status_change): New decls.
3386 * process.c (create_process): Avoid disaster if memory is exhausted
3387 while we're processing a vfork, by tightening the critical section
3389 (send_process_frame, process_sent_to, handle_pipe_signal)
3390 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
3392 (send_process): No need for setjmp/longjmp any more, since the
3393 SIGPIPE stuff is now gone. Instead, report an error if errno
3395 (record_child_status_change): Now extern. PID and W are now args.
3396 Return void, not bool. All callers changed.
3397 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
3398 Remove. All uses removed. This bug should be fixed now in a
3400 (wait_for_termination_1): Use waitpid rather than sigsuspend,
3401 and record the child status change directly. This avoids the
3402 need to futz with the signal mask.
3403 (process_fatal_action): Move here from emacs.c.
3404 (emacs_sigaction_flags): New function, containing
3405 much of what used to be in emacs_sigaction_init.
3406 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
3407 caught by emacs, to make races less likely.
3408 (deliver_process_signal): Rename from handle_on_main_thread.
3410 (BACKTRACE_LIMIT_MAX): Now at top level.
3411 (thread_backtrace_buffer, threadback_backtrace_pointers):
3413 (deliver_thread_signal, deliver_fatal_thread_signal):
3414 New functions, for more-accurate delivery of thread-specific signals.
3415 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
3416 (deliver_arith_signal): Handle in this thread, not
3417 in the main thread, since it's triggered by this thread.
3418 (maybe_fatal_sig): New function.
3419 (init_signals): New arg DUMPING so that we can be more accurate
3420 about whether we're dumping. Caller changed.
3421 Treat thread-specific signals differently from process-general signals.
3422 Block all signals while handling fatal error; that's safer.
3423 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
3425 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
3426 Ignore SIGPIPE unless batch.
3427 (emacs_backtrace): Output backtrace for the appropriate thread,
3428 which is not necessarily the main thread.
3429 * syssignal.h: Include <stdbool.h>.
3430 (emacs_raise): New macro.
3431 * xterm.c (x_connection_signal): Remove; no longer needed
3432 now that we use sigaction.
3433 (x_connection_closed): No need to mess with sigmask now.
3434 (x_initialize): No need to reset SIGPIPE handler here, since
3435 init_signals does this for us now.
3437 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3439 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
3440 background rect may be larger (Bug#12245).
3442 2012-09-23 Chong Yidong <cyd@gnu.org>
3444 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
3446 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3448 * .gdbinit: Just stop at fatal_error_backtrace.
3449 See Stefan Monnier's request in
3450 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
3451 Remove no-longer-used query of system type.
3453 2012-09-22 Chong Yidong <cyd@gnu.org>
3455 * search.c (Freplace_match): Doc fix (Bug#12325).
3457 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
3459 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
3460 (Fline_end_position): Doc fix.
3462 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
3464 2012-09-22 Chong Yidong <cyd@gnu.org>
3466 * dispextern.h (struct image_type): Add new slot, storing a type
3467 initialization function.
3469 * image.c (define_image_type): Call the image initializer function
3470 if it is defined. Arguments and return value changed.
3471 (valid_image_p, make_image): Callers changed.
3472 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
3473 (gif_type, imagemagick_type, svg_type, gs_type):
3474 Add initialization functions.
3475 (Finit_image_library): Call lookup_image_type.
3476 (CHECK_LIB_AVAILABLE): Macro deleted.
3477 (lookup_image_type): Call define_image_type here, rather than via
3478 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
3479 (syms_of_image): Move define_image_type calls for xbm_type and
3480 pbm_type to lookup_image_type.
3482 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3484 * keyboard.c (timer_check_2): Move calculation of 'timers' and
3485 'idle_timers' from here ...
3486 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
3487 lists, to avoid infloops when the timer does something stupid,
3488 like reinvoke itself with the same or smaller time-out.
3491 2012-09-22 Martin Rudalics <rudalics@gmx.at>
3493 * window.c (Fsplit_window_internal): Handle only Qt value of
3494 Vwindow_combination_limit separately.
3495 (Qtemp_buffer_resize): New symbol.
3496 (Vwindow_combination_limit): New default value.
3499 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3501 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
3502 the new overlay string. (Bug#10159)
3504 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3506 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
3507 or that fprintf is async-signal-safe. POSIX doesn't require
3510 2012-09-22 Chong Yidong <cyd@gnu.org>
3512 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
3515 2012-09-22 Kenichi Handa <handa@gnu.org>
3517 * composite.c (composition_reseat_it): Handle the case that a
3518 grapheme cluster is not covered by a single font (Bug#12352).
3520 2012-09-21 Chong Yidong <cyd@gnu.org>
3522 * image.c (define_image_type): Avoid adding duplicate types to
3523 image_types (Bug#12463). Suggested by Jörg Walter.
3525 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3527 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
3528 (print_load_command_name): Add case LC_DATA_IN_CODE.
3529 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
3531 2012-09-21 Glenn Morris <rgm@gnu.org>
3533 * eval.c (Frun_hook_with_args_until_success)
3534 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
3536 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
3538 * fileio.c (Ffile_selinux_context): Only call freecon when
3539 lgetfilecon succeeded.
3540 (Fset_file_selinux_context): Likewise. (Bug#12444)
3542 2012-09-21 Eli Zaretskii <eliz@gnu.org>
3544 * xdisp.c (try_window_reusing_current_matrix): Under bidi
3545 reordering, locate the cursor by calling set_cursor_from_row; if
3546 that fails, clear the desired glyph matrix before returning a
3547 failure indication to the caller. Fixes leaving garbled display
3548 when fast scrolling with a down-key. (Bug#12403)
3549 (compute_stop_pos_backwards): Fix a typo that caused crashes while
3550 scrolling through multibyte text.
3552 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
3554 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
3555 calling mark_vectorlike since that's the one that marks the window.
3556 (mark_discard_killed_buffers): Mark the final cdr.
3557 * window.h (struct window): Move prev/next_buffers to the
3558 non-standard fields.
3559 * window.c (make_window): Initialize prev/next_buffers manually.
3561 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
3563 Omit unused arg EXPECTED from socket hooks.
3564 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
3565 * nsterm.m (ns_term_init):
3566 * termhooks.h (struct terminal.read_socket_hook):
3567 * w32inevt.c (w32_console_read_socket):
3568 * w32term.c (w32_read_socket):
3569 * xterm.c (XTread_socket):
3570 Omit unused arg EXPECTED. All callers changed.
3571 (store_user_signal_events): Return void, not int, since callers no
3572 longer care about the return value. All uses changed.
3574 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
3576 * w32gui.h (XParseGeometry): Do not declare.
3578 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
3580 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
3581 Ignore 'expected'. See Eli Zaretskii in
3582 <http://bugs.gnu.org/12471#8> (last line).
3584 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
3585 (XParseGeometry): Now static. Substitute extremal values for
3586 values that are out of range.
3588 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
3590 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
3592 * nsfns.m (XParseGeometry): Remove.
3593 (Fx_create_frame): Call x_set_offset to correctly interpret
3594 top_pos in geometry.
3596 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
3597 (Fx_parse_geometry): If there is a space in string, call
3598 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
3600 2012-09-17 Eli Zaretskii <eliz@gnu.org>
3602 * search.c (scan_buffer): Use character positions in calls to
3603 region_cache_forward and region_cache_backward, not byte
3604 positions. (Bug#12196)
3606 * w32term.c (w32_read_socket): Set pending_signals to 1, like
3607 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
3609 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
3610 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
3611 emacs_blocked_malloc, now deleted.
3613 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
3615 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
3616 The workaround was for improving performance on Solaris 2.4, but
3617 is getting in the way now. Emacs will still work if someone is
3618 still running Solaris 2.4 in a museum somewhere; Sun dropped
3619 support for Solaris 2.4 in 2003.
3620 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
3621 * process.c (create_process) [HAVE_WORKING_VFORK]:
3622 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
3623 since Emacs no longer uses vfork on that platform.
3625 2012-09-17 Glenn Morris <rgm@gnu.org>
3627 * emacs.c: Use COPYRIGHT.
3629 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
3631 Remove configure's --without-sync-input option (Bug#12450).
3632 When auditing signal-handling in preparation for cleaning it up,
3633 I found that SYNC_INPUT has race conditions and would be a real
3634 pain to fix. Since it's an undocumented and deprecated
3635 configure-time option, now seems like a good time to remove it.
3636 Also see <http://bugs.gnu.org/11080#16>.
3637 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
3638 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
3639 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3640 (malloc_hysteresis):
3641 (check_depth) [XMALLOC_OVERRUN_CHECK]:
3642 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
3643 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
3644 (dont_register_blocks, bytes_used_when_reconsidered)
3645 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
3646 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
3647 [!SYSTEM_MALLOC && !SYNC_INPUT]:
3648 Remove. All uses removed.
3649 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
3650 implementation, one that depends on whether the new macro
3651 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
3653 * atimer.c (run_timers, handle_alarm_signal):
3654 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
3655 (handle_async_input, process_pending_signals)
3656 (handle_input_available_signal, init_keyboard):
3657 * nsterm.m (ns_read_socket):
3658 * process.c (wait_reading_process_output):
3659 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
3660 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
3662 * xterm.c (XTread_socket):
3664 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
3665 * eval.c (handling_signal): Remove. All uses removed.
3666 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
3667 All uses replaced with the SYNC_INPUT version.
3668 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
3670 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3673 * font.c (Ffont_shape_gstring): Remove unused local.
3675 2012-09-16 Glenn Morris <rgm@gnu.org>
3677 * Makefile.in (clean): No longer run nextstep's clean.
3679 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
3681 (ns-app): Move here from ns.mk, and simplify.
3682 (clean): Simplify nextstep entry.
3683 * ns.mk: Remove file.
3685 2012-09-17 Kenichi Handa <handa@gnu.org>
3687 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
3688 not covert the last few charactes.
3690 2012-09-16 Kenichi Handa <handa@gnu.org>
3692 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
3693 here, but just check the validity of glyphs in the glyph-string.
3695 2012-09-16 Martin Rudalics <rudalics@gmx.at>
3697 * window.c (Fwindow_parameter, Fset_window_parameter):
3698 Accept any window as argument (Bug#12452).
3700 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
3702 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
3703 to ns_term_init to avoid memory leak.
3705 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
3706 explicit retain/release.
3707 (ns_term_init): Only allow one display. Initialize outerpool and
3710 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3712 Port _setjmp fix to POSIXish hosts as well as Microsoft.
3713 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
3714 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
3715 the Microsoft problem in a different way, by altering ../nt/config.nt.
3717 2012-09-15 Eli Zaretskii <eliz@gnu.org>
3732 * w16select.c: Remove inclusion of setjmp.h, as it is now included
3733 by lisp.h. This completes removal of setjmp.h inclusion
3734 erroneously announced in the previous commit. (Bug#12446)
3736 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
3739 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
3740 not defined as a macro. The latter happens on MS-Windows.
3743 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3745 Port better to POSIX hosts lacking _setjmp (Bug#12446).
3746 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
3747 Some instances of '#include <setjmp.h>' removed, if the
3748 only reason for the instance was because "lisp.h" was included.
3749 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
3750 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
3751 and _longjmp with the new symbols. Emacs already uses _setjmp if
3752 available, so this change affects only POSIXish hosts that have
3753 sigsetjmp but not _setjmp, such as some versions of Solaris and
3754 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
3755 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
3756 (png_load_body) [HAVE_PNG]:
3757 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
3758 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
3759 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
3760 since PNG requires jmp_buf. This is the only exception to the
3761 general rule that we now use sys_setjmp and sys_longjmp.
3762 This exception is OK since this code does not change the signal
3763 mask or longjmp out of a signal handler.
3765 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
3767 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3768 Include "syssignal.h", for 'main_thread'.
3770 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
3772 Avoid out-of-range marker position (Bug#12426).
3773 * insdel.c (replace_range, replace_range_2):
3774 Adjust markers before overlays, as suggested by comments.
3775 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
3776 Remove redundant check before calling offset_intervals.
3778 2012-09-14 Martin Rudalics <rudalics@gmx.at>
3780 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
3781 current buffer (Bug#12387).
3783 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
3785 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
3787 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3789 Use a more backwards-compatible timer format (Bug#12430).
3790 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
3791 vector element, not from the 4th, since PSECS is now at the end.
3792 (Fcurrent_idle_time): Doc fix.
3794 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
3796 Function to mark objects and remove killed buffers at once.
3797 * alloc.c (discard_killed_buffers): Rename to ...
3798 (mark_discard_killed buffers) ... new name. Add marking
3799 of remaining objects. Fix comment. Adjust users.
3800 (mark_object): Do not touch frame buffer lists here.
3801 * frame.c (delete_frame): Reset frame buffer lists here.
3803 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3805 Better workaround for GNOME bug when --enable-gcc-warnings.
3806 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
3807 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
3808 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
3810 Simplify SIGIO usage (Bug#12408).
3811 The code that dealt with SIGIO was crufty and confusing, e.g., it
3812 played tricks like "#undef SIGIO" but these tricks were not used
3813 consistently. Simplify mostly by not #undeffing standard symbols,
3814 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
3815 or not as we please) rather than "defined SIGIO" (standard symbol
3816 that we probably shouldn't #undef).
3817 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
3818 Modules that need it can include it.
3819 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
3820 * dispextern.h (ignore_sigio): New decl.
3821 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
3822 unconditionally, since it's now a no-op if !USABLE_SIGIO.
3823 * emacs.c (shut_down_emacs):
3824 * keyboard.c (kbd_buffer_store_event_hold):
3825 Use ignore_sigio rather than invoking 'signal' directly.
3826 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
3828 (FIONREAD, SIGIO): Do not #undef.
3829 (tty_read_avail_input): Use #error rather than a syntax error.
3830 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
3831 for I_PIPE, used by SETUP_SLAVE_PTY.
3832 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
3833 * sysdep.c (croak): Remove; no longer needed. This bit of
3834 temporary code, with Fred N. Fish's comment that it's temporary,
3835 has been in Emacs since at least 1992!
3836 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
3837 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
3838 * syssignal.h (croak): Remove decl.
3839 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
3840 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
3841 now that we're termios-only.
3842 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
3843 * term.c (dissociate_if_controlling_tty): Use #error rather than
3846 Work around GCC and GNOME bugs when --enable-gcc-warnings.
3847 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
3848 to work around GNOME bug 683906.
3849 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
3850 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
3851 This works around GCC bug 54561.
3853 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
3855 More fixes for 'volatile' and setjmp/longjmp.
3856 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
3857 * image.c (struct png_load_context) [HAVE_PNG]: New type.
3858 (png_load_body) [HAVE_PNG]:
3859 (jpeg_load_body) [HAVE_JPEG]:
3860 New function, with most of the old parent function's body.
3861 (png_load) [HAVE_PNG]:
3862 (jpeg_load) [HAVE_JPEG]:
3863 Invoke the new function, to avoid longjmp munging our locals.
3864 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
3865 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
3866 longjmp is passed 2, as the C standard doesn't guarantee this.
3867 Instead, store the failure code into mgr->failure_code.
3869 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
3871 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
3872 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
3873 (syms_of_keyboard): Remove support for unread-command-char.
3875 2012-09-12 Eli Zaretskii <eliz@gnu.org>
3877 * w32proc.c (sys_kill): If PID is our process ID and the signal is
3878 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
3879 violation. (Bug#12426)
3881 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
3883 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
3885 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
3887 * eval.c: Add `inhibit-debugger'.
3888 (Qinhibit_debugger): New symbol.
3889 (call_debugger): Bind it instead of Qdebug_on_error.
3890 (maybe_call_debugger): Test Vinhibit_debugger.
3891 (syms_of_eval): Define inhibit-debugger.
3892 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
3893 (syms_of_xdisp): Remove inhibit-debug-on-message.
3895 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
3897 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
3898 If a nonvolatile local variable is written before a _longjmp to
3899 the frame containing the variable, and is read after the _longjmp,
3900 the value read is indeterminate. Some local variables of type
3901 'struct handler' and 'struct catchtag' are used in this way, so
3902 mark each of their slots as volatile if the slot can be set before
3903 _longjmp and read afterwards.
3904 * lisp.h (struct handler): var and chosen_clause are now volatile.
3905 (struct catchtag): val, next, and pdlcount are now volatile.
3907 * bidi.c (bidi_push_it, bidi_pop_it):
3908 * fns.c (copy_hash_table):
3909 * image.c (define_image_type):
3910 * keyboard.c (kbd_buffer_store_event_hold):
3911 * process.c (Fprocess_send_eof):
3912 * xfaces.c (x_create_gc) [HAVE_NS]:
3913 * xgselect.c (xg_select):
3914 Prefer assignment to memcpy when either will do.
3916 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
3917 Use pointer-to-a-pointer to simplify and avoid a NILP check each
3918 time an item is removed. No need to mark this function 'inline';
3919 the compiler knows better than we do.
3921 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
3923 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
3924 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
3925 to change_frame_size (Bug#12388).
3926 (windowDidResize:): Pass YES to updateFrameSize.
3928 * nsterm.h: Add delay parameter to updateFrameSize.
3930 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
3932 Discard killed buffers from deleted window and frame objects.
3933 This reduces an amount of references to killed buffers and
3934 helps GC to reclaim them faster.
3935 * alloc.c (discard_killed_buffers): New function.
3936 (mark_object): Use it for deleted windows and frames.
3937 (mark_object): If symbol's value is set up for a killed buffer
3938 or deleted frame, restore its global binding.
3939 * data.c (swap_in_global_binding): Add GC notice.
3940 (swap_in_symval_forwarding): Use convenient set_blv_where.
3941 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
3942 * window.h: ... to here.
3944 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
3946 Convenient macro to check whether the buffer is live.
3947 * buffer.h (BUFFER_LIVE_P): New macro.
3948 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
3949 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
3951 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3953 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
3954 composition cases (Bug#12364).
3956 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
3957 overhang of succeeding glyphs overlapping box cursor.
3959 * w32term.c (x_draw_glyph_string): Likewise.
3961 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
3963 Simplify, document, and port floating-point (Bug#12381).
3964 The porting part of this patch fixes bugs on non-IEEE platforms
3965 with frexp, ldexp, logb.
3966 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
3968 * floatfns.c: Simplify discussion of functions that Emacs doesn't
3969 support, by removing commented-out code and briefly listing the
3970 C89 functions excluded. The commented-out stuff was confusing
3971 maintenance, e.g., we thought we needed cbrt but it was commented out.
3972 (logb): Remove decl; no longer needed.
3973 (isfinite): New macro, if not already supplied.
3974 (isnan): Don't replace any existing macro.
3975 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
3976 are present on all C89 platforms.
3977 (Ffrexp): Do not special-case zero, as frexp does the right thing
3979 (Flogb): Do not use logb, as it doesn't have the desired meaning
3980 on hosts that use non-base-2 floating point. Instead, stick with
3981 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
3982 frexp, to avoid getting an unspecified result.
3984 * xdisp.c (Qinhibit_debug_on_message): Now static.
3986 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
3988 * nsterm.m (ns_update_begin): Set clip path to whole view by using
3989 NSBezierPath (Bug#12131).
3991 2012-09-10 Chong Yidong <cyd@gnu.org>
3993 * fns.c (Fdelq, Fdelete): Doc fix.
3995 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
3997 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
3998 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
4000 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
4002 * lisp.h (make_lisp_ptr): New macro to replace XSET.
4003 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
4006 2012-09-09 Eli Zaretskii <eliz@gnu.org>
4008 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
4009 left fringe if the window has a left margin. This avoids leaving
4010 traces of the cursor because its leftmost pixel is not drawn over.
4012 * dispnew.c (update_window_line): When the left margin area of a
4013 screen line is updated, set the redraw_fringe_bitmaps_p flag of
4014 that screen line. (Bug#12277)
4016 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
4018 Assume C89 or later for math functions (Bug#12381).
4019 This simplifies the code, and makes it a bit smaller and faster,
4020 and (most important) makes it easier to clean up signal handling
4021 since we can stop worring about floating-point exceptions in
4022 library code. That was a problem before C89, but the problem
4023 went away many years ago on all practical Emacs targets.
4024 * data.c, image.c, lread.c, print.c:
4025 Don't include <math.h>; no longer needed.
4026 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
4027 might be autoconfigured, as that never happens.
4029 * doprnt.c (DBL_MAX_10_EXP):
4030 * print.c (DBL_DIG):
4031 Remove. C89 or later always defines these.
4032 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
4033 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
4034 (arith_error, domain_error, domain_error2):
4035 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
4036 no longer needed -- we simply return what C returns. All uses removed.
4037 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
4039 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
4040 Remove. All uses expanded, as these macros are no longer used
4041 more than once and are now more trouble than they're worth.
4042 (Ftan): Use tan, not sin / cos.
4043 (Flogb): Assume C89 frexp.
4044 (fmod_float): Assume C89 fmod.
4045 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
4046 (init_floatfns): Remove. All uses removed.
4048 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4050 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
4051 compositeToPoint for OSX < 10.6 (Bug#12390).
4053 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
4055 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
4056 This produces more-accurate results.
4058 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4060 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
4061 changes (Bug#12088).
4063 2012-09-08 Chong Yidong <cyd@gnu.org>
4065 * syntax.c (Fstring_to_syntax): Doc fix.
4067 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4069 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
4070 in the internal border.
4071 (x_set_window_size): Remove static variables and their usage.
4072 (ns_redraw_scroll_bars): Fix NSTRACE arg.
4073 (ns_after_update_window_line, ns_draw_fringe_bitmap):
4074 Remove fringe/internal border adjustment (Bug#11052).
4075 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
4076 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
4077 (ns_fix_rect_ibw): Remove.
4078 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
4079 (ns_dumpglyphs_box_or_relief): Ditto.
4080 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
4082 (ns_dumpglyphs_image): Ditto.
4083 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
4085 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
4086 their usage. Add fringe_extended_p and its use as in other terms.
4087 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
4088 scroll bar was removed.
4089 (updateFrameSize): New function.
4090 (windowDidResize): Move code to updateFrameSize and call it.
4092 * nsterm.h (EmacsView): Add updateFrameSize.
4094 2012-09-07 Chong Yidong <cyd@gnu.org>
4096 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
4098 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
4100 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4102 More signal-handler cleanup (Bug#12327).
4103 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
4104 Problem introduced when merging patches. Noted by Eli Zaretskii in
4105 <http://bugs.gnu.org/12327#67>.
4106 * floatfns.c: Comment fix.
4107 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
4108 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
4109 and anyway the declaration is harmless even if SIGDANGER is not defined.
4110 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
4111 defined BROKEN_FIONREAD). systty.h formerly did this, but other
4112 source files not surprisingly expected syssignal.h to define, or
4113 not define, SIGIO, and it's cleaner to do it that way, for consistency.
4114 Include <sys/ioctl.h>, for FIONREAD.
4115 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
4116 This eliminates a problem whereby other files mysteriously had
4117 to include "syssignal.h" before including "systty.h" if they
4118 wanted to use "#ifdef SIGIO".
4120 2012-09-07 Eli Zaretskii <eliz@gnu.org>
4122 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
4124 * w32.c (sigemptyset): Empty the set.
4125 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
4127 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
4129 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
4131 * alloc.c (mark_buffer): Revert unsafe marking optimization.
4132 (mark_object): Likewise for frame objects.
4134 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4136 * syssignal.h (handle_on_main_thread): Always declare,
4137 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
4138 This ports to platforms without HAVE_PTHREAD.
4140 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4142 Signal-handler cleanup (Bug#12327).
4143 Emacs's signal handlers were written in the old 4.2BSD style with
4144 sigblock and sigmask and so forth, and this led to some
4145 inefficiencies and confusion. Rewrite these to use
4146 pthread_sigmask etc. without copying signal sets around. Also,
4147 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
4148 'signal', and instead use functions that do not attempt to take
4149 over the system name space. This patch causes Emacs's text
4150 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
4151 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
4152 Do not include <signal.h> or "syssignal.h", as these
4153 modules do not use signals.
4154 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
4155 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
4156 Do not include <signal.h>, as "syssignal.h" does that for us now.
4157 * atimer.c (sigmask_atimers): New function.
4158 (block_atimers, unblock_atimers): New functions,
4159 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
4161 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
4162 no longer needed here.
4163 * emacs.c (main): Inspect existing signal handler with sigaction,
4164 so that there's no need to block and unblock SIGHUP.
4165 * sysdep.c (struct save_signal): New member 'action', replacing
4166 old member 'handler'.
4167 (save_signal_handlers, restore_signal_handlers):
4168 Use sigaction instead of 'signal' to save and restore.
4169 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
4170 New function. All users of 'signal' modified to use set_sighandler
4171 if they're writeonly, and to use sys_signal if they're read+write.
4172 (emacs_sigaction_init, forwarded_signal): New functions.
4173 (sys_signal): Remove. All uses replaced by calls to sigaction
4174 and emacs_sigaction_init, or by direct calls to 'signal'.
4175 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
4176 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
4177 all uses replaced by pthread_sigmask etc. calls.
4178 * syssignal.h: Include <signal.h>.
4179 (emacs_sigaction_init, forwarded_signal): New decls.
4180 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
4181 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
4182 (sigmask, sys_sigmask): Remove; no longer needed.
4183 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
4184 (sigblock, sigunblock, sigfree):
4185 (sigsetmask) [!defined sigsetmask]:
4186 Remove. All uses replaced by pthread_sigmask.
4187 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
4188 no longer need to be replaced, and its typical old uses
4189 are now done via emacs_sigaction_init and sigaction.
4190 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
4191 (sys_sigdel): Remove; unused.
4192 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
4194 2012-09-06 Eli Zaretskii <eliz@gnu.org>
4196 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
4197 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
4199 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4201 Explicitly mark buffer_defaults and buffer_local_symbols.
4202 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
4203 mark_local_symbols here.
4204 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
4205 since special buffers aren't marked here any more.
4206 (allocate_buffer): Chain new buffer with all_buffers here...
4207 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
4209 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
4210 (syms_of_buffer): Remove staticpro of the above.
4211 (init_buffer_once): Set names for buffer_defaults and
4212 buffer_local_symbols.
4214 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4216 Use bool for booleans in font-related modules.
4217 * font.c (font_intern_prop, font_style_to_value)
4218 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
4219 (generate_otf_features, font_check_otf_features, font_check_otf)
4220 (font_match_p, font_list_entities, font_at):
4221 * fontset.c (fontset_id_valid_p, reorder_font_vector
4222 (fontset_find_font, Fset_fontset_font)
4223 (face_suitable_for_char_p) [0]:
4224 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
4225 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
4226 (m17n_flt_initialized, ftfont_shape_by_flt):
4227 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
4228 * nsfont.m (nsfont_draw):
4229 * w32font.c (w32font_draw):
4230 * w32term.c (x_draw_glyphless_glyph_string_foreground):
4231 Use bool for booleans.
4232 * font.h: Adjust to above API changes.
4233 (struct font, struct font_driver, struct font_driver_list):
4234 Use bool for booleans.
4235 (struct font): Remove useless member encoding_type.
4237 * fontset.c, xftfont.c: Omit unnecessary static decls.
4239 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4241 * alloc.c (mark_object): Revert window marking code
4242 since it's unsafe for the Fset_window_configuration.
4244 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4246 Fix race conditions with signal handlers and errno (Bug#12327).
4247 Be more systematic about preserving errno whenever a signal
4248 handler returns, even if it's not in the main thread. Do this by
4249 renaming signal handlers to distinguish between signal delivery
4250 and signal handling. All uses changed.
4251 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
4252 * data.c (deliver_arith_signal): Rename from arith_error.
4253 * dispnew.c (deliver_window_change_signal): Rename from
4254 window_change_signal.
4255 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
4256 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
4257 * keyboard.c (deliver_input_available_signal): Rename from
4258 input_available_signal.
4259 (deliver_user_signal): Rename from handle_user_signal.
4260 (deliver_interrupt_signal): Rename from interrupt_signal.
4261 * process.c (deliver_pipe_signal): Rename from send_process_trap.
4262 (deliver_child_signal): Rename from sigchld_handler.
4263 * atimer.c (handle_alarm_signal):
4264 * data.c (handle_arith_signal):
4265 * dispnew.c (handle_window_change_signal):
4266 * emacs.c (handle_fatal_signal, handle_danger_signal):
4267 * keyboard.c (handle_input_available_signal):
4268 * keyboard.c (handle_user_signal, handle_interrupt_signal):
4269 * process.c (handle_pipe_signal, handle_child_signal):
4270 New functions, with the actual signal-handling code taken from the
4271 original respective signal handlers, sans the sporadic attempts to
4272 preserve errno, since that's now done by handle_on_main_thread.
4273 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
4274 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
4275 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4277 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4278 Move initialization of main_thread to sysdep.c's init_signals.
4279 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
4280 our usage, and simplifies the mainline code.
4281 (record_child_status_change): New static function, as a helper
4282 for handle_child_signal, and with most of the old child handler's
4284 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
4285 (handle_child_signal): Use the above.
4286 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4287 Moved here from emacs.c.
4288 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
4289 code moved here from emacs.c's main function.
4290 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
4291 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
4292 This lets callers save and restore errno properly.
4294 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4296 Remove redundant or unused things here and there.
4297 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
4298 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
4299 * editfns.c (Fcompare_buffer_substrings): Likewise.
4300 * frame.h (struct terminal, struct font_driver_list):
4301 Remove redundant declarations.
4302 * window.h (Qleft, Qright): Likewise.
4304 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4306 Do not mark objects from deleted buffers, windows and frames.
4307 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
4308 (mark_object): Likewise for windows and frames.
4310 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4312 * alloc.c (valid_lisp_object_p): Treat killed buffers,
4313 buffer_defaults and buffer_local_symbols as valid objects.
4314 Return special value to denote them.
4316 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4318 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
4319 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
4320 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
4321 (file_name_absolute_p, Fsubstitute_in_file_name):
4322 (check_executable, check_writable, Ffile_accessible_directory_p)
4323 (Fset_file_selinux_context, Fdefault_file_modes)
4324 (Finsert_file_contents, choose_write_coding_system)
4325 (Fwrite_region, build_annotations, a_write, e_write)
4327 * filelock.c (boot_time_initialized, get_boot_time)
4328 (get_boot_time_1, lock_file_1, within_one_second):
4329 * floatfns.c (in_float):
4330 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
4331 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
4332 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
4333 * lisp.h (struct Lisp_Hash_Table.cmpfn):
4334 * window.c (compare_window_configurations):
4335 Use bool for booleans.
4336 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
4337 (Fdefault_file_modes): Now mode_t, not int, for modes.
4338 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
4339 (internal_delete_file): Now returns void, not a (boolean) int,
4340 since nobody was looking at the return value.
4341 * lisp.h, window.h: Adjust to above API changes.
4343 * xdisp.c (set_message): Simplify and reindent last change.
4345 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
4347 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
4349 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
4351 * eval.c (call_debugger): Make the function non-static so that we
4352 can call it from set_message.
4354 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
4355 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
4357 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4359 Give more-useful info on a fatal error (Bug#12328).
4360 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
4361 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
4362 of doing the work ourselves.
4363 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
4364 do most of the work.
4365 (fatal_error_backtrace): New function, taken from the guts
4366 of the old fatal_error_signal, but with a new option to output
4368 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
4369 info about the signal than just its number.
4370 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
4371 * sysdep.c: Include <execinfo.h>
4372 (emacs_backtrace): New function, taken partly from the previous
4373 code of the 'die' function.
4374 (emacs_abort): Call fatal_error_backtrace rather than abort.
4376 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
4378 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
4379 eager (load-time) macro-expansion.
4380 * lisp.mk (lisp): Add macroexp.
4382 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4384 Simplify redefinition of 'abort' (Bug#12316).
4385 Do not try to redefine the 'abort' function. Instead, redo
4386 the code so that it calls 'emacs_abort' rather than 'abort'.
4387 This removes the need for the NO_ABORT configure-time macro
4388 and makes it easier to change the abort code to do a backtrace.
4389 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
4390 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
4391 Remove; sysdep.c's emacs_abort now takes its place.
4392 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
4393 'abort' changed to use 'emacs_abort'.
4394 * msdos.c (dos_abort) [defined abort]: Remove; not used.
4395 (abort) [!defined abort]: Rename to ...
4396 (emacs_abort): ... new name.
4397 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
4398 the place of the old 'abort' in emacs.c.
4399 * w32.c, w32fns.c (abort): Do not #undef.
4400 * w32.c (emacs_abort): Rename from w32_abort.
4402 2012-09-04 Eli Zaretskii <eliz@gnu.org>
4404 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
4405 offsets[j].dv, since the y axis of the screen coordinates points
4406 down, while the y axis of the font definition coordinates points
4407 up. This fixes display of Arabic diacritics such as KASRA and
4408 KASRATAN. (Bug#11860)
4410 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4412 Be more systematic about _setjmp vs setjmp.
4413 * alloc.c (test_setjmp, mark_stack):
4414 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
4415 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
4416 (png_load, my_error_exit, jpeg_load):
4417 * process.c (send_process_trap, send_process):
4418 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
4419 The underscored versions are up to 30x faster on some hosts.
4420 Formerly, the code used setjmp+longjmp sometimes and
4421 _setjmp+_longjmp at other times, with no particular reason to
4422 prefer setjmp+longjmp.
4424 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
4426 Fix minor problem found by static checking.
4427 * buffer.c (Fdelete_all_overlays): Return nil.
4429 2012-09-03 Martin Rudalics <rudalics@gmx.at>
4431 * buffer.c (Fdelete_all_overlays): New function.
4433 2012-09-03 Chong Yidong <cyd@gnu.org>
4435 * gtkutil.c: Add extern decl for Qxft.
4437 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
4439 * emacs.c, eval.c: Use bool for boolean.
4440 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
4441 (malloc_using_checking) [DOUG_LEA_MALLOC]:
4442 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
4443 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)

4446 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
4447 (maybe_call_debugger, Fbacktrace):
4448 * process.c (read_process_output, exec_sentinel):
4449 Use bool for booleans.
4450 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
4451 All callers changed.
4452 * eval.c (interactive_p): Omit always-true boolean argument
4453 EXCLUDE_SUBRS_P. All callers changed.
4454 * dispextern.h, lisp.h: Reflect above API changes.
4455 * firstfile.c (dummy): Use the address of 'main', whose signature
4456 won't change, instead of the address of 'initialize', whose
4457 signature just changed from int to bool.
4458 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
4459 * msdos.c (fatal_error_in_progress): ... from here.
4460 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
4462 (redisplay_internal, unwind_redisplay): Simply clear
4463 REDISPLAYING_P when unwinding, instead of saving its previous,
4464 always-false value and then restoring it.
4466 Clean up some extern decls.
4467 Mostly, this hoists extern decls out of .c files and into .h files.
4468 That way, we're more likely to catch errors if the interfaces change.
4469 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
4470 declare xg_mark_data.
4471 * dispextern.h (x_frame_parm_handlers):
4473 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
4474 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
4475 (Qultra_bold, Qoblique, Qitalic):
4476 Move extern decl here from .c file.
4477 * alloc.c (xg_mark_data) [USE_GTK]:
4479 * eval.c (Qlexical_binding):
4480 * fns.c (time) [!HAVE_UNISTD_H]:

4489 * xfont.c (x_clear_errors):
4490 * xterm.c (x_frame_parm_handlers):
4491 Remove now-redundant extern decls.
4492 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
4493 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
4495 * xfaces.c: Remove unnecessary static decls.
4496 * xterm.c (updating_frame): Remove decl of nonexistent object.
4498 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
4499 when building globals.h, as the objects that are not built on
4500 this host are not needed to compile C files on this host.
4502 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
4504 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
4506 * frame.h: Add missing prototype for x_wm_set_size_hint.
4508 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

4512 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
4513 (Fsubstitute_command_keys):

4532 * keyboard.c (decode_timer):
4533 Use bool for boolean.
4534 * intervals.h, lisp.h, systime.h: Reflect above API changes.
4535 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
4537 2012-09-02 Chong Yidong <cyd@gnu.org>

4542 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
4544 * makefile.w32-in (CCL_H, W32FONT_H): New macros.

4550 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
4552 2012-09-01 Eli Zaretskii <eliz@gnu.org>
4554 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
4555 more than one grapheme cluster passed to the shaper: compute the
4556 offset adjustment values separately for each cluster. (Bug#11860)
4558 * image.c: Restore mistakenly removed inclusion of w32.h. Without
4559 it, GCC doesn't see prototypes of w32_delayed_load, and complains
4560 about implicit conversions from integer to pointer.
4562 2012-09-01 Daniel Colascione <dancol@dancol.org>
4564 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window

4614 window-system headers. Declare Vlibrary_cache when compiling for
4617 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
4618 window system declarations.
4620 * frame.h: Move common functions here: set_frame_menubar,
4621 x_set_window_size, x_sync, x_get_focus_frame,
4622 x_set_mouse_position, x_set_mouse_pixel_position,
4623 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

4634 window-system headers.
4636 * emacs.c: Include TERM_HEADER.
4638 * dispnew.c: Include TERM_HEADER instead of listing all possible

4650 * lisp.h (mark_ttys): Remove prototype.
4651 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
4652 to mark_ttys because all possible values of 'top_frame' slot are
4653 the frames which are reachable from Vframe_list.
4654 * term.c (mark_ttys): Remove.
4655 (init_tty): Safely initialize 'top_frame' slot with Qnil.

4674 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
4675 does not become zero (Bug#12234).
4677 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
4679 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
4680 for GCC 4.7.1 x86-64.
4682 2012-08-30 Glenn Morris <rgm@gnu.org>
4684 * lread.c (init_lread): For out-of-tree builds, only add the
4685 source directory's site-lisp dir to the load-path if it exists,
4686 consistent with in-tree builds. (Bug#12302)
4688 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
4690 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize

4704 Code formatting change.
4705 (timeout_handler:): Set timer_fired to YES.
4706 (runDialogAt:): Set timer_fired to NO.
4707 Handle click on close button as quit.
4709 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
4710 Add window_closed and button_values. Add void as return value for
4711 add(Button|String|Split). addButton takes int instead of Lisp_Object.
4712 Add process_dialog as new member.
4714 2012-08-28 Eli Zaretskii <eliz@gnu.org>
4716 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
4717 is not one of the heaps we manage. (Bug#12242)
4719 2012-08-28 Glenn Morris <rgm@gnu.org>
4721 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)

4852 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
4853 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
4854 not a boolean 'int', since callers never look at the return value.

4857 (emacs_mule_string_char): Remove unused extern decls.
4858 (struct iso_2022_spec, struct coding_system):

4874 buffer doesn't appear in the selected window, go to its old
4877 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
4879 Special MEM_TYPE_SPARE to denote reserved memory.
4880 * alloc.c (enum mem_type): New memory type.
4881 (refill_memory_reserve): Use new type for spare memory.

4911 (map_sub_char_table):
4912 Use bool for boolean.

4915 * character.h, charset.h: Adjust to match previous changes.
4916 * character.h (char_printable_p): Remove decl of nonexistent function.
4917 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
4918 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
4919 are all boolean, so make them single-bit bitfields.
4921 * lisp.h (ASET): Remove attempt to detect side effects.
4922 It was meant to be temporary and it often doesn't work,
4923 because when IDX has side effects the behavior of IDX==IDX
4924 is undefined. See Stefan Monnier in
4925 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
4927 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
4929 * lisp.h (functionp): New function (extracted from Ffunctionp).
4930 (FUNCTIONP): Use it.
4931 * eval.c (Ffunctionp): Use it.
4933 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
4935 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
4936 as that's faster and simpler than static storage. Don't bother
4937 with the g_main_context_query overhead if g_main_context_pending
4938 says no events are pending.
4939 (gfds, gfds_size): Remove these static vars.
4940 (xgselect_initialize): Remove; no longer needed.
4941 All uses and decls removed.
4943 * emacs.c (fatal_error_signal_hook): Remove.
4944 All uses removed. This leftover from old code was always 0.
4946 * casefiddle.c, casetab.c, category.c: Use bool for boolean.

4971 Use bool for booleans, instead of int.
4972 * lisp.h, process.h: Adjust prototypes to match above changes.
4973 * callint.c (Fcall_interactively): Don't assume the mark's
4974 offset fits in 'int'.

4987 Use bool for booleans, instead of int.
4988 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
4989 since the 1-or-0 return value is always ignored anyway.
4990 (mmap_initialized_p):
4991 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
4992 * buffer.h, lisp.h: Adjust prototypes to match above changes.
4994 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
4996 * bidi.c: Use bool for boolean.
4997 This is a bit more readable, and makes the text segment of bidi.o
4998 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
4999 Presumably it's faster too.

5009 (bidi_unshelve_cache): Adjust decls to match code.
5011 2012-08-23 Martin Rudalics <rudalics@gmx.at>
5013 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
5016 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5018 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
5019 * atimer.h: Include <stdbool.h>.
5021 2012-08-22 Dan Nicolaescu <dann@gnu.org>
5023 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
5024 compile time tests instead of run time tests on systems that do
5026 (FRAME_MAC_P): Remove leftover from deleted code.

5033 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
5035 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
5036 Otherwise, the compiler complains about (A?B:C) where B is void
5037 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
5038 (fontset_add): Return void, for FONTSET_ADD.
5040 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5042 * alloc.c: Use bool for booleans.
5043 (gc_in_progress, abort_on_gc)
5044 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5045 (dont_register_blocks) [GC_MALLOC_CHECK]:
5046 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
5047 (check_string_bytes, make_specified_string, memory_full)
5048 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
5049 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
5050 (mark_stack, valid_pointer_p, make_pure_string)
5051 (Fgarbage_collect, survives_gc_p, gc_sweep):
5052 Use bool for booleans, instead of int.
5053 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5054 Remove unused local.
5055 * alloc.c (PURE_POINTER_P):
5056 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
5057 * editfns.c (Fformat):
5058 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
5060 * fns.c (sweep_weak_table):
5061 * lisp.h (suppress_checking, push_message, survives_gc_p)
5062 (make_pure_string, gc_in_progress, abort_on_gc):
5063 * lread.c (readchar, read1):
5064 * print.c (Fprin1_to_string):
5065 * xdisp.c (push_message):
5066 Use bool for booleans affected directly or indirectly by
5069 Make recently-introduced setters macros.
5070 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
5071 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
5072 (set_fontset_default, set_fontset_fallback): Rename from their
5073 upper-case counterparts, and make them functions rather than macros.
5074 This is more consistent with the other recently-introduced setters.
5075 These don't need to be inline, since they're local.
5077 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
5079 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
5080 the loop (Bug#12247).
5082 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5084 * lisp.h (vcopy): Use memcpy rather than our own loop.
5085 This fixes a performance regression introduced by the recent
5086 addition of vcopy. This means 'vcopy' will need to be modified
5087 for a copying collector, but that's OK. Also, tighten the
5088 checking in the assertion.
5090 2012-08-21 Eli Zaretskii <eliz@gnu.org>
5092 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
5093 components for RTL text (Bug#11860). Adjust X-OFFSET of each
5094 non-base glyph for the width of the base character, according to
5095 what x_draw_composite_glyph_string_foreground expects.
5096 Generate WADJUST value according to composition_gstring_width's
5097 expectations, to produce correct width of the composed character.
5098 Reverse the sign of the DU offset produced by ScriptPlace.
5100 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5102 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
5104 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
5106 Avoid direct writes to contents member of struct Lisp_Vector.
5107 * lisp.h (vcopy): New function to copy data into vector.
5108 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
5109 * fns.c (Ffillarray): Use ASET.
5110 * keyboard.c (timer_check_2): Use AREF and ASET.
5111 (append_tool_bar_item, Frecent_keys): Use vcopy.
5112 * lread.c (read_vector): Use ASET.
5113 * msdos.c (Frecent_doskeys): Use vcopy.
5114 * xface.c (Finternal_copy_lisp_face): Use vcopy.
5115 (Finternal_merge_in_global_face): Use ASET and vcopy.

5121 the position of its buffer's point.
5122 (Fset_window_point): For the selected window always go in its
5123 buffer to the specified position.
5125 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
5127 Setter macros for fontsets.
5128 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
5129 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
5130 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
5133 2012-08-20 Glenn Morris <rgm@gnu.org>
5135 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
5136 Don't assume that `ln -f' works.
5138 2012-08-20 Eli Zaretskii <eliz@gnu.org>
5140 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
5141 and later about non-assignments with no effect. See discussion at
5142 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
5145 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5147 Inline setter functions for Lisp_Objects slots of struct specbinding.
5148 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
5151 2012-08-20 Martin Rudalics <rudalics@gmx.at>
5153 * window.c (select_window): Always make selected window's buffer
5156 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5158 Use AREF and ASET for docstrings of category tables.
5159 * category.h (CATEGORY_DOCSTRING): Use AREF.
5160 (SET_CATEGORY_DOCSTRING): Use ASET.
5161 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
5163 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5165 Inline setter functions for hash table members.
5166 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
5167 (set_hash_hash, set_hash_index): Rename with _slot suffix.
5168 (set_hash_key_and_value, set_hash_index, set_hash_next)
5169 (set_hash_hash): New functions.
5170 * charset.c, fns.c: Adjust users.
5172 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5174 Inline getter and setter functions for per-buffer values.
5175 * buffer.h (per_buffer_default, set_per_buffer_default)
5176 (per_buffer_value, set_per_buffer_value): New functions.
5177 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
5178 * buffer.c, data.c: Adjust users.
5180 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
5182 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
5184 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
5186 Rely on <config.h> + <unistd.h> to declare 'environ',
5187 as gnulib does this if the system doesn't.
5188 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
5189 Remove declaration. MS-Windows declares it on stdlib.h which is
5190 included by conf_post.h.
5191 * emacs.c (environ) [DOUG_LEA_MALLOC]:
5192 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
5193 * vm-limit.c: Include <unistd.h>, for 'environ'.
5195 * unexaix.c, unexcoff.c: Include "mem-limits.h".
5196 (start_of_data): Remove decl; mem-limits.h provides it.
5198 * xdisp.c (handle_invisible_prop): Make it a bit faster
5199 and avoid a gcc -Wmaybe-uninitialized diagnostic.
5201 2012-08-19 Chong Yidong <cyd@gnu.org>
5203 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
5206 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
5208 * .gdbinit: Use call instead of set when calling a function in the
5211 * data.c (set_internal): Don't use set_blv_found.
5212 (Fkill_local_variable): Likewise.
5214 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
5216 * nsfont.m (ns_ascii_average_width): Ensure the string
5217 ascii_printable is initialized with a null-terminated character
5218 array. Otherwise, it can contain undesired extra characters.
5220 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
5222 port new setting code to Sun C 5.8 2005/10/13
5223 * chartab.c, lisp.h (char_table_set, char_table_set_range):
5224 Return void, not Lisp_Object. Otherwise, the compiler
5225 complains about (A?B:C) where B is void and C is Lisp_Object
5226 when compiling CHAR_TABLE_SET, due to the recent change to
5227 the API of sub_char_table_set_contents.
5229 2012-08-18 Chong Yidong <cyd@gnu.org>
5231 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
5232 for the string case (Bug#3874).

5387 The old version was confusing because it used the same name
5388 'parent' for two different things.

5402 directly-specified attributes.
5403 (merge_face_ref): Recognize :font.
5405 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>

6059 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
6060 * w32.c (init_environment): Change the default values of many
6061 environment variables in dflt_envvars[] to NULL, to avoid pushing
6062 them into environment when they were not already defined.
6063 Remove the code that deletes site-lisp subdirectories from the default
6064 value of EMACSLOADPATH, as it is no longer needed.
6065 (check_windows_init_file): Now external, not static.
6066 Use Vload_path as is, without adding anything, as this function is now
6067 called when Vload_path is already set up.
6069 * w32.h (check_windows_init_file): Add prototype.
6071 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

6078 installation tree, as appropriate.
6080 * callproc.c (init_callproc_1): Call decode_env_path instead of
6081 doing its equivalent by hand.

6083 the code that sets Vexec_path run on MS-Windows.
6085 * lread.c (init_lread): Add comments to #ifdef's.
6087 * msdos.c (dos_set_window_size, IT_update_begin)

6099 Remove unnecessary casts involving pointers.
6100 These casts are no longer needed now that we assume C89 or later,

6114 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
6115 Remove unnecessary pointer casts.
6116 * alloc.c (record_xmalloc): New function.
6117 * lisp.h (record_xmalloc): New decl.
6118 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
6119 more like a function. This is because the pointer cast is not
6120 needed. All uses changed.
6121 * print.c (print_string, print_error_message): Avoid length recalc.
6123 Improve fix for macroexp crash with debugging (Bug#12118).
6124 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
6125 ARRAY_MARK_FLAG when checking subscripts, because ASET is
6126 not supposed to be invoked from the garbage collector.
6127 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
6128 (gc_aset): New function, which is like ASET but can be
6129 used in the garbage collector.

6158 with addition of handling of symlinks and support for 'lstat'.
6159 If possible, get file's attributes and security information by
6160 handle, not by name. Produce S_IFLNK bit for symlinks, when
6161 called from 'lstat'.
6162 (stat, lstat): New functions, call 'stat_worker'.
6163 (symlink, readlink, careadlinkat): Rewritten to create and resolve
6164 symlinks when the underlying filesystem supports them.
6166 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
6168 Fix macroexp crash on Windows with debugging (Bug#12118).
6169 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
6170 checking subscripts; problem introduced with the recent
6171 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
6172 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
6173 since it's used in non-static inline functions now.
6175 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
6176 Don't assume buffer size fits in 'int'. Remove unused local.

6193 * category.c (CATEGORY_INLINE):
6194 * character.c (CHARACTER_INLINE):
6195 * charset.c (CHARSET_INLINE):
6196 * composite.c (COMPOSITE_INLINE):
6197 * dispnew.c (DISPEXTERN_INLINE):
6198 * sysdep.c (SYSTIME_INLINE):
6199 Define to EXTERN_INLINE, so that the corresponding functions
6200 are compiled into code.
6201 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
6202 (INLINE_HEADER_END): New macros.
6203 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

6223 hard-coding the path separator.
6225 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
6227 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
6228 This how ASET and AREF are supposed to work, and makes
6229 it easier to think about future improvements. See
6230 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
6231 * charset.h (set_charset_attr): New function.

6613 (w32_kbd_patch_key, key_event): Use the codepage returned by
6614 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.

6723 the fix for 12036 would have avoided some of the problems noted in
6724 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
6725 would have been more obvious.

6735 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
6736 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
6737 not be usable in #if. This simplifies things.
6739 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
6741 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

6746 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
6747 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
6748 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
6749 Adjust to changes in lisp.h and emacs.c, by using

6752 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of

6754 instead of gdb_valbits.
6755 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
6756 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG

6758 (xboolvector): Get size from $->size, not $->header.size.
6759 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
6760 (xreload, hook-run, hookpost-run): Remove.
6761 * emacs.c: Include <verify.h>.
6762 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
6763 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):

7659 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
7660 Prefer snprintf to strncpy.
7661 * nsterm.m (ns_term_init):
7662 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
7663 * nsterm.m (ns_term_init):
7664 Avoid the need for strncpy, by using build_string or
7665 make_unibyte_string directly. Use dtoastr, not snprintf.
7666 * process.c (Fmake_network_process): Diagnose service names that
7667 are too long, rather than silently truncating them or creating
7668 non-null-terminated names.
7669 (Fnetwork_interface_info): Likewise, for interface names.
7670 * sysdep.c (system_process_attributes) [GNU_LINUX]:
7671 Prefer sprintf to strncat.
7672 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
7673 Prefer vsnprintf to vsprintf + strncpy.

7684 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
7685 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR

7698 Optimize pure C strings initialization.
7699 * lisp.h (make_pure_string): Fix prototype.
7700 (build_pure_c_string): New function, defined as static inline. This
7701 provides a better opportunity to optimize away calls to strlen when
7702 the function is called with compile-time constant argument.
7703 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
7704 argument, adjust users accordingly. Use build_pure_c_string where
7706 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
7707 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
7708 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
7710 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
7712 Avoid calls to strlen in miscellaneous functions.
7713 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
7714 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
7715 * lread.c (openp): Likewise.
7717 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
7719 Avoid calls to strlen in path processing functions.
7720 * fileio.c (file_name_as_directory): Add comment. Change to add
7721 srclen argument and return the length of result. Adjust users
7723 (directory_file_name): Fix comment. Change to add srclen argument,
7724 swap 1st and 2nd arguments to obey the common convention.
7725 Adjust users accordingly.
7726 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
7728 2012-07-10 Glenn Morris <rgm@gnu.org>
7730 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:

7735 * s/gnu.h (DATA_START): Move definitions to configure.
7737 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
7738 We include usg5-4-common.h, which defines them both.
7740 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
7741 O_RDONLY already includes it).
7743 Stop ns builds setting the EMACSLOADPATH environment variable.
7744 * nsterm.m (ns_load_path): Rename from ns_init_paths.
7745 Now it does not set EMACSLOADPATH, just returns the load-path string.
7746 * nsterm.h: Update accordingly.
7747 * lread.c [HAVE_NS]: Include nsterm.h.
7748 (init_lread) [HAVE_NS]: Use ns_load_path.

7751 2012-07-09 Glenn Morris <rgm@gnu.org>
7753 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
7754 since the included bsd-common.h does so.
7756 Stop ns builds setting the EMACSPATH environment variable.
7757 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
7758 (ns_init_paths): Do not set EMACSPATH.
7759 * nsterm.h (ns_exec_path): Add it.
7760 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
7763 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
7765 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
7767 * process.c (wait_reading_process_output): 'waitchannels' was unset
7768 when read_kbd || !NILP (wait_for_cell); fix this.
7770 Add GCC-style 'const' attribute to functions that can use it.
7771 * character.h (char_resolve_modifier_mask):
7772 * keyboard.h (make_ctrl_char):
7773 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

7782 Add decls with ATTRIBUTE_CONST.
7784 Minor improvements to make_formatted_string.
7785 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
7786 where int is good enough, as vsprintf returns an int.
7787 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
7789 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7791 Use make_formatted_string to avoid double length calculation.
7792 * lisp.h (make_formatted_string): New prototype.
7793 * alloc.c (make_formatted_string): New function.
7794 * buffer.c (Fgenerate_new_buffer_name): Use it.
7795 * dbusbind.c (syms_of_dbusbind): Likewise.

7816 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7818 Move marker debugging code under MARKER_DEBUG.
7819 * marker.c (MARKER_DEBUG): Move marker debugging code under
7820 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
7821 for bootstrap with --enable-checking (~3x slowdown reported
7822 by Juanma Barranquero <lekktu@gmail.com>).
7823 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
7825 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
7827 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
7828 See <http://bugs.gnu.org/11825#29>.
7830 2012-07-08 Eli Zaretskii <eliz@gnu.org>
7832 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
7833 has no font, use the frame's font. (Bug#11813)
7834 (display_line): Add commentary about displaying truncation glyphs
7836 (produce_special_glyphs): Move here from term.c.
7838 * term.c (produce_special_glyphs): Move to xdisp.c.
7840 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
7843 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
7845 * xdisp.c (display_line): Avoid warning about implicit declaration
7848 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
7850 * lisp.h: Remove empty conditional.
7852 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
7854 * lread.c (load_path_check): Now static.
7856 Fix some minor --with-ns problems found by static checking.
7857 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
7858 (x_set_font) [!HAVE_X_WINDOWS]:
7859 * image.c (xpm_load_image) [HAVE_NS]:
7860 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
7861 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
7862 Remove unused local.
7863 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
7864 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
7865 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
7866 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
7867 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
7868 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
7869 Fix pointer signedness problem.
7870 * xfaces.c (FRAME_X_FONT_TABLE):
7871 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
7873 2012-07-07 Glenn Morris <rgm@gnu.org>
7875 * lread.c (load_path_check): New function, split from init_lread.
7876 (init_lread): Reorganize. Motivation:
7877 If EMACSLOADPATH is set, check/warn about that rather than the
7878 defaults, which we are not going to use. Hence we can remove
7879 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
7880 Don't warn if site-lisp directories are missing.
7881 If not installed, start from a blank load-path, since
7882 PATH_LOADSEARCH refers to the eventual installation directories.
7884 2012-07-07 Eli Zaretskii <eliz@gnu.org>
7886 Support truncation and continuation glyphs on GUI frames, when
7887 fringes are disabled. (Bug#11832)
7888 * xdisp.c (init_iterator): Get dimensions of truncation and
7889 continuation glyphs even if on GUI frames.
7890 Adjust it->last_visible_x on GUI frames when the left or right fringes,
7891 or both, are absent.
7892 (start_display, move_it_in_display_line_to): Handle the case of a
7893 GUI frame without a fringe to display continuation or truncation
7895 (insert_left_trunc_glyphs): Support GUI frames: make sure
7896 truncation glyphs overwrite enough glyphs from the current line to
7897 have sufficient space in pixels.
7898 (display_line): Support truncation and continuation glyphs on GUI
7899 frames. If some spare pixels are left on the line after inserting
7900 the truncation glyphs, fill that space with a stretch glyph of a
7901 suitably computed width.
7903 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
7904 produce_glyphs, to support GUI sessions.
7906 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
7908 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
7910 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
7912 Do not require float-time's arg to fit in time_t (Bug#11825).
7913 This works better on hosts where time_t is unsigned, and where
7914 float-time is applied to the (negative) difference between two times.
7915 * editfns.c (decode_time_components): Last arg is now double *,
7916 not int *, and means to store all the result as a double, without
7917 worrying about whether the seconds part fits in time_t.
7918 All callers changed.
7919 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
7920 All callers changed.
7921 (Ffloat_time): Do not fail merely because the specified time falls
7922 outside of time_t range.
7924 2012-07-07 Glenn Morris <rgm@gnu.org>
7926 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

7932 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
7933 Update dependencies.
7935 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
7937 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7939 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

7941 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
7942 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
7943 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.

7946 * xfont.c (compare_font_names): Redo to omit the need for casts.
7948 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
7950 * xfns.c (Fx_change_window_property): Doc fix.
7951 * w32fns.c (Fx_change_window_property): Doc fix.
7953 * w32fns.c (Fx_window_property): Accept the same arguments as the
7954 X Windows version. Doc fix.
7955 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
7957 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
7958 Eli Zaretskii <eliz@gnu.org>
7960 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
7961 Windows-specific code from nt/config.nt moved here.
7962 Obsolete settings removed.
7964 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7966 * process.c: Avoid unnecessary calls to gettime.
7967 (wait_reading_process_output): Don't get the time of day
7968 when gobbling data immediately and not waiting, as there's no need
7969 for it in that case. This removes a FIXME.
7971 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
7973 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
7974 is defined (Bug#11768).
7976 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7978 Fix marker debugging code.
7979 * marker.c (byte_char_debug_check): Do not perform the check
7980 if buffer is not multibyte.
7981 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
7982 Call byte_char_debug_check with correct arguments.
7984 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7986 Compile marker debugging code only if ENABLE_CHECKING is defined.
7987 * marker.c (byte_char_debug_check, count_markers):
7988 Use only if ENABLE_CHECKING is defined.
7989 (byte_debug_flag): Remove.
7990 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
7991 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
7993 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7995 Avoid code repetition in marker-related functions.
7996 * marker.c (attach_marker): New function.
7997 (Fset_marker, set_marker_restricted, set_marker_both)
7998 (set_marker_restricted_both): Use it.
7999 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
8000 Consistently rename charno to charpos.
8001 (marker_position): Add eassert.
8002 (marker_byte_position): Convert to eassert.

8021 * window.c (save_window_save): Likewise.
8023 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8025 Do not use Fdelete_overlay in delete_all_overlays
8026 to avoid redundant calls to unchain_overlay.
8027 * buffer.c (drop_overlay): New function.
8028 (delete_all_overlays, Fdelete_overlay): Use it.
8029 * minibuf.c (get_minibuffer): Fix comment.
8031 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8033 Port to OpenBSD 5.1 amd64.
8034 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
8035 This is needed for OpenBSD, and should be harmless on all BSD systems.
8036 Also, include <sys/sysctl.h>, as it should be available on all
8037 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
8038 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
8039 use p_pid member, not kp_proc.pid.
8041 2012-07-06 Glenn Morris <rgm@gnu.org>
8043 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
8045 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
8047 More xmalloc and related cleanup.
8048 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
8049 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

8054 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
8055 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
8056 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
8058 Omit needless casts involving void * pointers and allocation.
8059 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
8060 as the former is more robust if P's type is changed.
8061 Prefer xzalloc to xmalloc + memset 0.
8062 Simplify malloc-or-realloc to realloc.
8063 Don't worry about xmalloc returning a null pointer.
8064 Prefer xstrdup to xmalloc + strcpy.
8065 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
8067 * keyboard.c (apply_modifiers_uncached): Prefer local array to
8068 alloca of a constant.
8070 2012-07-05 Eli Zaretskii <eliz@gnu.org>
8072 * xdisp.c (display_line): Fix horizontal pixel coordinates when
8073 hscroll is larger than the line width. Fixes long and futile
8074 looping inside extend_face_to_end_of_line (on a TTY) producing
8075 glyphs that are not needed and thrown away.
8077 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
8079 * marker.c (set_marker_restricted_both): Simplify by using
8082 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

8105 * xdisp.c (window_hscroll_limited): New function.
8106 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
8107 coordinates when window's hscroll is set to insanely large
8110 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
8112 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

8173 * fileio.c (time_error_value): Check the right error number.
8174 Problem reported by Troels Nielsen in
8175 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
8177 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8179 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
8180 This should be fixed in a better way; see Eli Zaretskii in
8181 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
8182 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
8184 * fileio.c (time_error_value): Rename from special_mtime.
8185 The old name's problems were noted by Eli Zaretskii in
8186 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
8188 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
8189 This variable's comment says Emacs needs at least one GDB-visible
8190 symbol of type enum pvec_type, to work around GDB problems.
8191 The symbol's value doesn't matter.
8193 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
8194 that causes compilation to fail on pre-C99 compilers.
8196 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
8198 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
8199 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
8201 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8203 * buffer.c (init_buffer_once): Fix initialization of
8204 headers for buffer_defaults and buffer_local_symbols.
8205 Reported by Juanma Barranquero <lekktu@gmail.com>.
8207 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
8209 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
8210 * lisp.h (enum pvec_type): Use fewer bits.
8211 (PSEUDOVECTOR_SIZE_BITS): New constant.
8212 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
8213 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
8214 change in pvec_type.
8215 (PSEUDOVECTOR_TYPEP): New macro.
8216 (TYPED_PSEUDOVECTORP): Use it.
8217 * fns.c (internal_equal): Adapt code to extract pvectype.

8219 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
8220 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
8221 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
8222 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
8223 (sweep_vectors): Use it. Use local var `total_bytes' instead of
8224 abusing vector->header.next.nbytes.
8225 (live_vector_p): Use PVEC_TYPE.
8226 (mark_object): Adapt code to extract pvectype. Use switch.
8228 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8230 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
8231 Tighten new eassert a bit.
8233 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8235 Fix compilation with --enable-gcc-warnings and -O1
8237 * doprnt.c (doprnt): Change type of tem to int, initialize
8238 to avoid compiler warning. Add eassert.
8239 * search.c (simple_search): Initialize match_byte to avoid
8240 compiler warning. Add eassert.
8242 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8244 Avoid weird behavior with large horizontal scrolls.
8245 Without this change, for example, large hscroll values would
8246 mess up Emacs's display on Fedora 15 x86, presumably due to
8247 overflows in int calculations in the display code.
8248 Also, if buffers had long lines, Emacs would freeze.
8249 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
8250 (set_window_hscroll): New function, containing the old guts of
8251 Fset_window_hscroll. Return the clipped value.
8252 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
8253 This avoids the need to check against PTRDIFF_MAX.
8255 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
8257 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8259 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
8261 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8263 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
8264 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
8265 since GCC 4.4.6 issues a bogus warning for them.
8267 Fix bugs in file timestamp newness comparisons.
8268 * fileio.c (Ffile_newer_than_file_p):
8269 * lread.c (Fload): Use full timestamp resolution of files,
8270 not just the 1-second resolution, so that files that are only
8271 slightly newer still count as newer.
8272 * fileio.c (Ffile_newer_than_file_p): Don't assume file
8273 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
8275 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
8277 * fileio.c: Improve handling of file time marker. (Bug#11852)
8278 (special_mtime): New function.
8279 (Finsert_file_contents, Fverify_visited_file_modtime):
8280 Use it to set special mtime values consistently.
8282 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
8284 * fileio.c (Finsert_file_contents): Properly handle st_mtime
8285 marker for non-existing file. (Bug#11852)
8287 2012-07-03 Glenn Morris <rgm@gnu.org>
8289 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
8290 and did not make it into globals.h).
8292 2012-07-03 Tom Tromey <tromey@redhat.com>
8294 * window.c (Fset_window_margins, Fset_window_fringes)
8295 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
8296 * textprop.c (Fprevious_property_change): No longer static.
8297 * syntax.c (Fsyntax_table_p): No longer static.

8328 * xterm.h: Remove EXFUN.
8330 2012-07-03 Glenn Morris <rgm@gnu.org>
8332 * lisp.h (Frandom): Make it visible to C.
8333 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
8334 buffer for invisible buffers. (Bug#1229)
8336 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8338 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
8339 values which aren't power of 2.
8340 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
8341 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
8344 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
8346 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
8348 * alloc.c (mark_object): Revert part of last patch to use `switch'.
8350 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8352 * alloc.c (allocate_vector_block): Remove redundant
8353 calls to mallopt if DOUG_LEA_MALLOC is defined.
8354 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
8355 avoid calls to mallopt if zero_vector is returned.
8357 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8359 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
8360 is enabled, avoid dereferencing NULL current_sblock if
8363 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8365 Cleanup basic buffer management.
8366 * buffer.h (struct buffer): Change layout to use generic vector
8367 marking code. Fix some comments. Change type of 'clip_changed'
8368 to bitfield. Remove unused #ifndef old.
8369 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
8370 (GET_OVERLAYS_AT): Fix indentation.
8371 (for_each_per_buffer_object_at): New macro.

8375 * alloc.c (allocate_buffer): Adjust to match new layout of
8376 struct buffer. Fix comment.
8377 (mark_overlay): New function.

8379 Lisp area of struct buffer.
8380 (mark_object): Use it. Adjust marking of misc objects
8381 and related comments.
8383 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
8385 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
8386 wrapper that is not needed because the wrapped code is a no-op (zero
8387 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
8388 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
8390 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
8392 * alloc.c (mark_buffer): Simplify. Remove prototype.
8393 (mark_object): Add comment. Reorganize marking of vector-like
8394 objects. Use CHECK_LIVE for all vector-like objects except buffers
8395 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
8396 Avoid redundant calls to mark_vectorlike for bool vectors.
8398 2012-06-30 Glenn Morris <rgm@gnu.org>
8400 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
8402 * epaths.in (PATH_SITELOADSEARCH): New.
8403 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
8404 This is rather than relying on --enable-locallisppath elements
8405 having "site-lisp" in their names. (Bug#10208#25, 11658)
8407 2012-06-30 Eli Zaretskii <eliz@gnu.org>
8409 * w32proc.c (sys_select): Accept and ignore one more argument.
8411 * w32.c (emacs_gnutls_pull): Call select with one more argument.
8413 * sysselect.h [DOS_NT]: Don't include sys/select.h.
8414 (pselect) [!MS_DOS]: Redirect to sys_select.
8416 * sysdep.c: Don't include dos.h and dosfns.h.
8418 * process.c (sys_select):
8419 * msdos.c (sys_select): Accept one more argument and ignore it.
8421 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
8422 adapt data types and code to that.
8425 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
8426 which clashes with the gnulib function of the same name.
8428 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
8430 * font.c (font_style_to_value, font_style_symbolic)
8431 (font_prop_validate_style): Add type checks for values in
8434 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
8436 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
8439 2012-06-29 Eli Zaretskii <eliz@gnu.org>
8441 * xdisp.c (try_window_id): Undo last change.
8443 * w32.c (getwd): Adjust commentary about startup_dir.
8444 (init_environment): Always call sys_access, even in non-MSVC
8445 builds. Don't chdir to the directory of the Emacs executable.
8446 This undoes code from 1997 which was justified by the need to
8447 "avoid conflicts when removing and renaming directories". But its
8448 downside was that every relative file name was being interpreted
8449 relative to the directory of the Emacs executable, which can never
8450 be TRT. In particular, it broke sys_access when called with
8451 relative file names.
8452 (sys_access): Map GetLastError to errno.
8454 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8456 * window.h (struct window): Change type of 'fringes_outside_margins'

8460 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
8463 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
8465 * gnutls.c (emacs_gnutls_handshake):
8466 Add QUIT to make the loop interruptible.
8468 2012-06-29 Glenn Morris <rgm@gnu.org>
8470 * charset.c (init_charset): Make lack of etc/charsets fatal.
8472 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8474 * editfns.c (region_limit): Fix type mismatch.
8476 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8478 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
8479 undefined. Convert from xassert to eassert.
8480 * nsmenu.m: Convert from xassert to eassert.
8481 * nsterm.m: Likewise.
8483 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
8485 * editfns.c (region_limit): Clip to narrowing (bug#11770).
8487 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
8489 Avoid integer overflow on scroll-left and scroll-right.
8490 * window.c (HSCROLL_MAX): New macro.
8491 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
8492 overflow when requested scroll falls outside ptrdiff_t range.
8494 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8496 * window.h (struct window): Change type of 'hscroll',
8497 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
8498 'last_modified' and 'last_overlay_modified' to EMACS_INT.
8499 Adjust users accordingly.
8500 * xdisp.c (try_cursor_movement): Replace type check with eassert.
8501 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
8502 from EMACS_INT to ptrdiff_t.
8503 (make_window): Omit redundant initialization.
8505 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
8507 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
8509 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8511 * window.h (struct window): Change type of 'use_time' and
8512 'sequence_number' from Lisp_Object to int.
8513 * frame.c (make_frame): Adjust users accordingly.
8514 * print.c (print_object): Likewise.

8521 enabled with --enable-checking=[all,glyphs] configure option.
8522 Fix GLYPH_DEBUG usage assuming that it may be undefined,
8523 adjust comments accordingly.

8574 avoid GCC warning about unused macro.
8576 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
8578 * alloc.c (allocate_string): Omit intervals initialization.
8579 * alloc.c (make_uninit_multibyte_string): Initialize intervals
8580 as in make_pure_string and make_pure_c_string.
8582 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
8584 * alloc.c (allocate_string): Fix last change.
8586 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

8636 * alloc.c: Remove build_string.
8637 * lisp.h: Define build_string as static inline. This provides
8638 a better opportunity to optimize away calls to strlen when the
8639 function is called with compile-time constant argument.
8640 * image.c (imagemagick_error): Convert to build_string.
8641 * w32proc.c (sys_spawnve): Likewise.
8642 * xterm.c (x_term_init): Likewise.
8644 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
8646 Use sprintf return value instead of invoking strlen on result.
8647 In the old days this wasn't portable, since some sprintf
8648 implementations returned char *. But they died out years ago and
8649 Emacs already assumes sprintf returns int.
8650 Similarly for float_to_string.
8651 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
8652 * ccl.c (ccl_driver):
8653 * character.c (string_escape_byte8):

8656 * print.c (print_object):
8657 * xdisp.c (message_dolog):
8658 * xfns.c (syms_of_xfns):
8659 Use sprintf or float_to_string result to avoid need to call strlen.
8660 * data.c (Fnumber_to_string):
8661 Use make_unibyte_string, since the string must be ASCII.
8662 * lisp.h, print.c (float_to_string): Now returns int length.
8663 * term.c (produce_glyphless_glyph):
8664 Use sprintf result rather than recomputing it.
8666 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
8667 * Makefile.in (ALL_CFLAGS):
8668 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
8669 * gmalloc.c, regex.c: Include <config.h> unconditionally.
8671 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
8673 * dispextern.h (xstrcasecmp): Define to library function
8674 strcasecmp if available.

8690 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
8692 * gtkutil.c (get_utf8_string): Remove redundant assignment.
8693 sprintf already null-terminates its output.
8695 * xfns.c (x_window): Remove redundant cast.
8697 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
8699 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
8700 `const char *' to `char *' to avoid compiler warning.
8702 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
8704 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
8705 instead of truncating it to 63 (admittedly a generous limit).
8707 * process.c: Fix spelling and caps in comments.
8709 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
8711 * emacs.c (setpgrp): Remove definition, unused.

8758 Remove unnecessary forward decls.
8760 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
8762 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).

8764 * dispnew.c (Fsleep_for, sit_for):
8765 * keyboard.c (kbd_buffer_get_event):
8766 * process.c (Faccept_process_output):
8767 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
8768 This improves on the previous patch, which introduced a bug
8769 when time_t is unsigned and as wide as intmax_t.
8770 See <http://bugs.gnu.org/9000#51>.
8772 2012-06-23 Eli Zaretskii <eliz@gnu.org>
8774 * dispnew.c (sit_for, Fsleep_for):
8775 * keyboard.c (kbd_buffer_get_event):

8788 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
8789 Privately reported by Herbert J. Skuhra.
8790 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
8792 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
8793 not make_lisp_timeval, when the argument is of type EMACS_TIME.
8795 2012-06-23 Eli Zaretskii <eliz@gnu.org>
8797 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
8798 last argument of make_unibyte_string.
8800 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
8801 language ID in the event parameters.
8803 * w32term.c (w32_read_socket): Put the new keyboard codepage into
8804 event.code, not the obscure "character set ID".

8827 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
8828 Privately reported by Herbert J. Skuhra.

8835 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
8837 Support higher-resolution time stamps (Bug#9000).
8838 The time stamps are only nanosecond-resolution at the C level,
8839 since that's the best that any real-world system supports now.
8840 But they are picosecond-resolution at the Lisp level, as that's
8841 easy, and leaves room for future OS improvements.
8843 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
8846 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
8847 Don't get current time unless it's needed.
8849 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
8850 now provides it if it's absent.
8851 (start_atimer): Port to higher-res time stamps.
8852 Check for time stamp overflow. Don't get current time more
8853 often than is needed.
8855 * buffer.h (struct buffer): Buffer modtime now has high resolution.
8856 Include systime.h, not time.h.
8857 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
8859 * dired.c: Include stat-time.h.
8860 (Ffile-attributes): File times now have higher resolution.
8862 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
8863 (struct image): Timestamp now has higher resolution.
8865 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
8866 has at least microseconds now. All uses removed.
8867 (update_frame, update_single_window, update_window, update_frame_1)
8868 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
8869 (duration_to_sec_usec): Remove; no longer needed.
8871 * editfns.c (time_overflow): Now extern.
8872 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
8873 (float-time, Fformat_time_string, Fcurrent_time_string)

8876 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
8877 (decode_time_components, lisp_seconds_argument): New functions.
8878 (make_time): Now static.
8879 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
8880 Report an error if the time is invalid, rather than having the caller
8883 * fileio.c: Include <stat-time.h>
8884 (Fcopy_file): Copy higher-resolution time stamps.
8885 Prefer to set the time stamp via a file descriptor if that works.
8886 (Fset_file_times, Finsert_file_contents, Fwrite_region)
8887 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
8888 (Fvisited_file_modtime, Fset_visited_file_modtime):
8889 Support higher-resolution time stamps.
8891 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
8893 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
8895 * image.c (prepare_image_for_display, clear_image_cache)
8896 (lookup_image): Port to higer-resolution time stamps.
8898 * keyboard.c (start_polling, bind_polling_period):
8899 Check for time stamp overflow.
8900 (read_char, kbd_buffer_get_event, timer_start_idle)
8901 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
8902 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
8903 Port to higher-resolution time stamps. Do not assume time_t is signed.
8904 (decode_timer): New function. Timers are now vectors of length 9,
8905 not 8, to accommodate the picosecond component.
8906 (timer_check_2): Use it.
8908 * nsterm.m (select_timeout, timeval_subtract): Remove.
8909 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
8910 as they're a bit more accurate and handle overflow better.
8911 (ns_select): Change prototype to be compatible with pselect.
8912 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
8913 * nsterm.h (ns_select): Adjust prototype.
8915 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
8916 us-resolution time stamps.
8917 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
8919 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
8921 * lisp.h (time_overflow): New decl.
8922 (wait_reading_process_output): First arg is now intmax_t, not int,
8923 to accommodate larger waits.
8925 * process.h (struct Lisp_Process.read_output_delay):
8926 Now counts nanoseconds, not microseconds.
8927 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
8929 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
8930 (wait_reading_process_output):
8931 Port to ns-resolution time stamps.
8932 (Faccept_process_output, wait_reading_process_output):
8933 Check for time stamp overflow. Do not assume time_t is signed.
8934 (select_wrapper): Remove; we now use pselect.
8935 (Fprocess_attributes): Now generates ns-resolution time stamps.
8937 * sysdep.c: Include utimens.h. Don't include utime.h
8938 or worry about struct utimbuf; gnulib does that for us now.
8939 (gettimeofday): Remove; gnulib provides a substitute.
8940 (make_timeval): New function.
8941 (set_file_times): Now sets ns-resolution time stamps.
8942 New arg FD; all uses changed.
8943 (time_from_jiffies, ltime_from_jiffies, get_up_time)
8944 (system_process_attributes):
8945 Now returns ns-resolution time stamp. All uses changed.
8946 Check for time stamp overflow.
8948 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
8949 provides a substitute now.
8951 * systime.h: Include timespec.h rather than sys/time.h and time.h,
8952 since it guarantees struct timespec.
8953 (EMACS_TIME): Now struct timespec, so that we can support
8954 ns-resolution time stamps.
8955 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
8956 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
8957 (EMACS_USECS): Remove.
8958 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
8959 so multiply the arg by 1000 before storing it.
8960 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
8962 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
8963 Port to ns-resolution time stamps.
8964 (EMACS_TIME_NEG_P): Remove; replaced by....
8965 (EMACS_TIME_SIGN): New macro.
8966 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
8967 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.

8969 (make_timeval, make_lisp_time, decode_time_components): New decls.
8970 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
8971 that it mishandled time_t overflow. You can't compare by subtracting!
8972 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
8973 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
8975 * term.c: Include <sys/time.h>.
8976 (timeval_to_Time): New function, for proper overflow wraparound.

8983 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
8984 (w32_get_internal_run_time):
8985 Port to higher-resolution Emacs time stamps.
8986 (ltime): Now accepts single 64-bit integer, as that's more convenient
8989 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
8991 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
8992 for compatibility with pselect. Support ns-resolution time stamps.
8994 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
8996 * xselect.c (wait_for_property_change, x_get_foreign_selection):
8997 Check for time stamp overflow, and support ns-resolution time stamps.
8999 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
9000 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
9001 (timeval_subtract): Remove; no longer needed.
9002 (XTflash, XTring_bell, x_wait_for_event):
9003 Port to ns-resolution time stamps. Don't assume time_t is signed.
9005 2012-06-22 Chong Yidong <cyd@gnu.org>

9009 2012-06-22 Eli Zaretskii <eliz@gnu.org>
9011 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
9012 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
9013 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
9014 staticidx goes up to 1597 out of 1600 = 0x640.)
9016 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
9018 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
9019 Otherwise, the umask might be mistakenly 0 while handling input signals.
9021 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
9023 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

9039 frame's selected window and its terminal's top-frame.
9040 (unwind_format_mode_line): Restore them.
9041 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
9043 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
9044 since tty frames can be explicitly named.
9045 (prepare_menu_bars): Likewise.
9047 * term.c (Ftty_top_frame): New function.
9049 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
9051 Port byte-code-meter to modern targets.
9052 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
9053 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
9054 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
9055 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
9056 (METER_1, METER_2): Simplify.
9058 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
9060 * data.c (Fdefalias): Return `symbol' (bug#11686).
9062 2012-06-18 Martin Rudalics <rudalics@gmx.at>
9064 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
9065 gets killed during executing of this function (Bug#11665).
9066 Try to always return Qt when the buffer has been actually killed.
9067 (Vkill_buffer_query_functions): In doc-string say that functions
9068 run by this hook should not change the current buffer.
9070 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
9072 Fix recently-introduced process.c problems found by static checking.
9073 * process.c (write_queue_push, write_queue_pop, send_process):
9074 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.
9075 (write_queue_pop): Fix pointer signedness problem.

9286 code works fine either way, and efficiency is not a concern here,
9287 as the union type is for debugging, not for production.
9288 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
9289 Use an inline function on all platforms when using the union type,
9290 since this is simpler and 'static inline' can be used portably
9292 (LISP_INITIALLY_ZERO): New macro.

9434 * doprnt.c (doprnt): Truncate multibyte char correctly.
9435 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
9436 would mishandle a string argument "Xc" if X was a multibyte
9437 character of length 2: it would truncate after X's first byte
9438 rather than including all of X.

9511 Change type of 'force_start', 'optional_new_start',
9512 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
9513 fields from Lisp_Object to bitfield. Adjust users accordingly.

9521 and 'double' in a couple of places.
9523 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9525 * xdisp.c (handle_stop): Detect whether we have overlay strings
9526 loaded by testing it->current.overlay_string_index to be
9527 non-negative, instead of checking whether n_overlay_strings is
9528 positive. (Bug#11587)

9540 maybe_unify_char, which was the cause of relocation of buffer text
9543 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9545 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
9546 for the duration of call to load_charset, to avoid problems with
9547 callers of maybe_unify_char that access buffer text through C
9550 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
9551 decrement the inhibition flag, instead of just setting or
9554 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
9556 Remove obsolete '#define static' cruft.
9557 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
9558 This #undef was "temporary" in 2000; it is no longer needed
9559 now that '#define static' has gone away.
9560 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
9561 (gray_bitmap_bits): Remove; no longer needed.
9562 All uses replaced with definiens.
9563 * xterm.c: Include "bitmaps/gray.xbm".
9565 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
9567 Clean up __executable_start, monstartup when --enable-profiling.
9568 The following changes affect the code only when profiling.
9569 * dispnew.c (__executable_start): Rename from safe_bcopy.
9570 Define only on platforms that need it.
9571 * emacs.c: Include <sys/gmon.h> when profiling.
9572 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
9573 (__executable_start): Remove decl, since lisp.h does it now.
9574 (safe_bcopy): Remove decl; no longer has that name.
9575 (main): Coalesce #if into single bit of code, for simplicity.
9576 Cast pointers to uintptr_t, since standard libraries want integers
9578 * lisp.h (__executable_start): New decl.
9580 2012-05-31 Glenn Morris <rgm@gnu.org>
9582 * image.c (Fimagemagick_types): Doc fix.
9584 2012-05-30 Jim Meyering <meyering@redhat.com>
9586 * callproc.c (Fcall_process_region): Include directory component

9601 * lread.c (read1): Tiny simplification.
9603 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
9605 Do not create empty overlays with the evaporate property (Bug#9642).
9606 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
9607 Bug#9642, but explicitly check that the buffer the overlay would
9608 be moved to is live and rearrange lines to make sure that errors
9609 will not put the overlay in an inconsistent state.
9610 (Fdelete_overlay): Cosmetics.
9612 2012-05-28 Eli Zaretskii <eliz@gnu.org>
9614 * w32term.c (my_bring_window_to_top): New function.
9615 (x_raise_frame): Use handle returned by DeferWindowPos, which
9616 could be different from the original one.

9620 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
9621 by calling BringWindowToTop.
9623 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
9624 (WM_EMACS_END): Increase by one.
9626 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
9628 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
9629 This avoids undefined behavior that might cause the eassert
9630 to not catch an out-of-range value.
9632 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
9634 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
9635 Update dependencies.
9637 2012-05-27 Eli Zaretskii <eliz@gnu.org>

9644 when referring to sectname field in printf format.
9646 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
9648 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
9649 Only r_alloc_inhibit_buffer_relocation needed to be added;
9650 the others were already declared.
9652 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
9653 before checking whether it's out of range. Put the check inside
9655 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
9657 2012-05-27 Ken Brown <kbrown@cornell.edu>
9659 * callproc.c (Fcall_process): Restore a line that was accidentally
9660 commented out in the 2011-02-13 change (bug#11547).
9662 2012-05-27 Eli Zaretskii <eliz@gnu.org>
9664 * lisp.h [REL_ALLOC]: Add prototypes for external functions
9665 defined on ralloc.c.
9667 * buffer.c [REL_ALLOC]: Remove prototypes of
9668 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
9669 they are now on lisp.h.
9671 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
9673 * search.c (search_buffer): Use it to inhibit relocation of buffer
9674 text while re_search_2 is doing its job, because re_search_2 is
9675 passed C pointers to buffer text. (Bug#11519)
9677 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
9680 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
9681 state after an additional call to move_it_in_display_line_to, keep
9682 the values of it->max_ascent and it->max_descent found for the
9684 (pos_visible_p): Revert the comparison against bottom_y to what it
9685 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
9688 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
9690 Fix coding-related core dumps with gcc -ftrapv.
9691 The code was computing A - B, where A and B are pointers, and B is
9692 random garbage. This can lead to core dumps on platforms that
9693 have special pointer registers, and it also leads to core dumps on
9694 x86-64 when compiled with gcc -ftrapv. The fix is to compute
9695 A - B only when B is initialized properly.
9696 * coding.c (coding_set_source, coding_set_destination): Return void.
9697 (coding_change_source, coding_change_destinations): New functions,
9698 with the old behaviors of coding_set_source and coding_set_destination.
9699 All callers that need an offset changed to use these new functions.
9701 2012-05-26 Glenn Morris <rgm@gnu.org>
9703 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
9705 2012-05-26 Eli Zaretskii <eliz@gnu.org>
9707 Extend mouse support on W32 text-mode console.
9708 * xdisp.c (draw_row_with_mouse_face):
9709 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
9711 * w32console.c: Include window.h.
9712 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
9714 (initialize_w32_display): Initialize mouse-highlight data.
9716 * w32inevt.c: Include termchar.h and window.h.
9717 (do_mouse_event): Support mouse-autoselect-window. When the mouse
9718 moves, call note_mouse_highlight. If help_echo changed, call
9719 gen_help_event to produce help-echo message in the echo area.
9720 Call clear_mouse_face if mouse_face_hidden is set in the mouse
9723 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
9725 * lread.c (read1): Simplify slightly to avoid an overflow warning
9726 with GCC 4.7.0 on x86-64.
9728 2012-05-26 Eli Zaretskii <eliz@gnu.org>
9730 * bidi.c (bidi_mirror_char): Revert last change: an int is
9731 definitely wide enough here.
9733 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
9735 Fix integer width and related bugs (Bug#9874).

9743 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
9745 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9746 (allocate_pseudovector):
9747 Use int, not EMACS_INT, where int is wide enough.
9748 (inhibit_garbage_collection, Fgarbage_collect):
9749 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9750 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
9751 int might not be wide enough.
9752 (bidi_cache_search, bidi_cache_find, bidi_init_it)

9755 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
9756 (bidi_level_of_next_char, bidi_move_to_visually_next):
9757 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9758 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
9759 (Fkill_buffer, Fset_buffer_major_mode)

9763 (overlay_strings, recenter_overlay_lists)
9764 (adjust_overlays_for_insert, adjust_overlays_for_delete)
9765 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
9766 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
9767 (Foverlay_recenter, last_overlay_modification_hooks_used)
9768 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
9769 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9770 (validate_region): Omit unnecessary test for b <= e,
9771 since that's guaranteed by the previous test.
9772 (adjust_overlays_for_delete): Avoid pos + length overflow.
9773 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
9774 (report_overlay_modification):
9775 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9776 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
9777 Omit pointer cast, which isn't needed anyway, and doesn't work
9778 after the EMACS_INT -> ptrdiff_t change.
9779 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
9780 * buffer.h: Adjust decls to match defn changes elsewhere.

9784 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
9785 not int, to avoid needless 32-bit limit on 64-bit hosts.
9786 (exec_byte_code): Use tighter memory-full test, one that checks
9787 for alloca overflow. Don't compute the address of the object just
9788 before an array, as that's not portable. Use EMACS_INT, not
9789 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
9790 * callint.c (Fcall_interactively):
9791 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9792 * callproc.c (call_process_kill, Fcall_process):
9793 Don't assume pid_t fits into an Emacs fixnum.

9802 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
9803 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9804 (casify_object): Avoid integer overflow when overallocating buffer.
9805 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
9806 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
9807 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
9808 * category.h (CATEGORYP): Don't assume arg is nonnegative.
9809 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
9810 integers are now checked earlier. All uses replaced with XINT.
9812 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9813 For CCL_MapSingle, check that content and value are in int range.
9814 (ccl_driver, Fregister_code_conversion_map):
9815 Check that Vcode_version_map_vector is a vector.
9816 (resolve_symbol_ccl_program): Check that vector header is in range.
9817 Always copy the vector, so that we can check its contents reliably
9818 now rather than having to recheck each instruction as it's being
9819 executed. Check that vector words fit in 'int'.
9820 (ccl_get_compiled_code, Fregister_ccl_program)
9821 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
9822 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
9823 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
9824 contents are in range.
9825 (Fccl_execute_on_string): Check that status is in range.
9826 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
9827 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
9828 Accept and return EMACS_INT, not int, because callers can pass values
9830 (c_string_width, strwidth, lisp_string_width, chars_in_text)

9833 (str_as_unibyte, str_to_unibyte, string_count_byte8)
9834 (string_escape_byte8, Fget_byte):
9835 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9836 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
9837 avoid mishandling large integers.
9838 * character.h: Adjust decls to match defn changes elsewhere.
9839 * charset.c (load_charset_map_from_file, find_charsets_in_text)

9847 (Fdefine_charset_internal): Check ranges here, more carefully.
9848 Don't rely on undefined behavior with signed left shift overflow.
9849 Don't assume unsigned int fits into fixnum, or that fixnum fits
9850 into unsigned int. Don't require max_code to be a valid fixnum;
9851 that's not true for gb10830 4-byte on a 32-bit host. Allow
9852 invalid_code to be a cons, for the same reason. Require code_offset
9853 to be a character. Avoid int overflow if max_char is close
9855 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
9856 this is intended anyway and avoids some undefined behavior.
9857 (load_charset_map): Pass unsigned, not int, as 2nd arg of
9858 INDEX_TO_CODE_POINT, as that's what it expects.
9859 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
9860 * charset.h (DECODE_CHAR): Return int, not unsigned;
9861 this is what was intended anyway, and it avoids undefined behavior.
9862 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
9863 integer-overflow issues.
9864 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
9865 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
9866 where the argument is EMACS_INT, and this behavior is not intended.
9867 * chartab.c (Fmake_char_table, Fset_char_table_range)
9868 (uniprop_get_decoder, uniprop_get_encoder):
9869 Don't assume fixnum fits in int.
9870 * cmds.c (move_point): New function, that does the gist of
9871 Fforward_char and Fbackward_char, but does so while checking
9872 for integer overflow more accurately.
9873 (Fforward_char, Fbackward_char): Use it.
9874 (Fforward_line, Fend_of_line, internal_self_insert)
9875 (internal_self_insert):
9876 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9877 Fix a FIXME, by checking for integer overflow when calculating
9878 target_clm and actual_clm.

9913 Don't access memory outside of the args array.
9914 (Fdefine_coding_system_internal): Check for charset-id overflow.
9915 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
9916 result of ENCODE_CHAR.

9934 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9935 * data.c (let_shadows_buffer_binding_p, let_shadows_global_binding_p):
9936 Do not attempt to compute the address of the object just before a
9937 buffer; this is not portable.
9939 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9940 (Faset): Use int, not EMACS_INT, where int is wide enough.
9941 (Fstring_to_number): Don't assume fixnums fit in int.

10653 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
10655 * lread.c (init_obarray): Declare Qt and Qnil as special.
10657 2012-05-14 Glenn Morris <rgm@gnu.org>
10659 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
10660 Put "libexec" before "bin", for the sake of init_callproc_1.
10662 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
10664 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
10666 * unexaix.c: Port to more-recent AIX compilers.
10667 (report_error, report_error_1, make_hdr, copy_sym)
10668 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
10669 Make arguments const char *, not char *, to avoid violations of C
10670 standard and to fix some AIX warnings reported by Gilles Pion.
10672 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10674 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
10675 already have overlays loaded.
10676 (handle_single_display_spec): Before returning without displaying
10677 fringe bitmap, synchronize the bidi iterator with the main display
10678 iterator, by calling iterate_out_of_display_property.
10679 (iterate_out_of_display_property): Detect buffer iteration by
10680 testing that it->string is a Lisp string.
10681 (get_next_display_element): When the current object is exhausted,
10682 and there's something on it->stack, call set_iterator_to_next to
10683 proceed with what's on the stack, instead of returning zero.
10684 (set_iterator_to_next): If called at the end of a Lisp string,
10685 proceed to consider_string_end without incrementing string
10686 position. Don't increment display vector index past the end of
10687 the display vector. (Bug#11417)
10688 (pos_visible_p): Don't report a position visible when move_it_to
10689 stopped at the last line of window, which happens to be scanned
10690 backwards by the bidi iteration. (Bug#11464)
10692 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10694 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
10695 and right-margin display specs even if the spec is invalid or we
10696 are on a TTY, and thus unable to display on the fringes.
10697 That's because the text with the property will not be displayed anyway,
10698 so we need to signal to the caller that this is a "replacing"
10699 display spec. This fixes display when the spec is invalid or we
10702 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
10704 * unexaix.c (make_hdr): Fix typo in prototype.
10705 This bug broke the build on AIX. Problem reported by Gilles Pion.
10707 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
10709 * keyboard.c (kbd_buffer_get_event): Read special events also in
10710 batch mode. (Bug#11415)
10712 2012-05-12 Glenn Morris <rgm@gnu.org>
10714 * ns.mk: Update for ns_appbindir no longer having trailing "/".
10716 2012-05-12 Eli Zaretskii <eliz@gnu.org>
10718 * lisp.mk (lisp): Add newcomment.elc.
10720 2012-05-12 Glenn Morris <rgm@gnu.org>
10722 * Makefile.in (MKDIR_P): New, set by configure.
10723 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
10725 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
10727 Remove unused function hourglass_started.
10728 * dispextern.h (hourglass_started):
10729 * w32fns.c (hourglass_started):
10730 * xdisp.c (hourglass_started): Remove.
10732 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
10734 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
10735 Update dependencies.
10737 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
10739 * xgselect.c (xg_select): Put maxfds+1 into a var.
10740 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
10742 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
10744 2012-05-10 Dave Abrahams <dave@boostpro.com>
10746 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
10747 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
10749 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
10751 * dbusbind.c (xd_registered_buses): New internal Lisp object.
10752 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
10753 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
10754 Initialize xd_registered_buses.
10756 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
10758 Untag more efficiently if USE_LSB_TAG.
10759 This is based on a proposal by YAMAMOTO Mitsuharu in
10760 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
10761 For an admittedly artificial (nth 8000 longlist) benchmark on
10762 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
10763 Emacs's overall text size by 1%.
10764 * lisp.h (XUNTAG): New macro.
10765 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
10766 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
10767 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
10768 * eval.c (Fautoload):
10769 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
10770 * frame.h (XFRAME): Use XUNTAG.
10772 Port recent dbusbind.c changes to 32-bit --with-wide-int.
10773 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
10774 Remove unportable assumptions about print widths of types like
10776 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
10777 intptr_t when converting between pointer and integer, to avoid GCC
10778 warnings about wrong width.
10780 2012-05-09 Eli Zaretskii <eliz@gnu.org>
10782 * w32proc.c (new_child): Force Windows to reserve only 64KB of
10783 stack for each reader_thread, instead of defaulting to 8MB
10784 determined by the linker. This avoids failures in creating
10785 subprocesses on Windows 7, see the discussion in this thread:
10786 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
10788 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
10790 Fix up display of the *Minibuf-0* buffer in the mini window.
10791 * keyboard.c (read_char): Don't clear the echo area if there's no
10793 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
10794 contents of *Minibuf-0*) if there's no message displayed in its stead.
10796 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
10798 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
10801 2012-05-06 Chong Yidong <cyd@gnu.org>
10803 * lisp.mk (lisp): Update.
10805 2012-05-05 Jim Meyering <meyering@redhat.com>
10807 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
10809 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
10811 * data.c (PUT_ERROR): New macro.
10812 (syms_of_data): Use it. Add new error type `user-error'.
10813 * undo.c (user_error): New function.
10814 (Fprimitive_undo): Use it.
10815 * print.c (print_error_message): Adjust print style for `user-error'.
10816 * keyboard.c (user_error): New function.
10817 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
10819 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
10821 Do not limit current-time-string to years 1000..9999.
10822 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
10823 (Fcurrent_time_string): Support any year that is supported by the
10824 underlying localtime representation. Don't use asctime, as it
10825 has undefined behavior for years outside the range -999..9999.
10827 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
10829 Fix race conditions involving setenv, gmtime, localtime, asctime.
10830 Without this fix, interrupts could mess up code that uses these
10831 nonreentrant functions, since setting TZ invalidates existing
10832 tm_zone or tzname values, and since most of these functions return
10833 pointers to static storage.
10834 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
10835 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
10836 Grow the critical sections to include not just invoking
10837 localtime/gmtime, but also accessing these functions' results
10838 including their tm_zone values if any, and any related TZ setting.
10839 (format_time_string): Last arg is now struct tm *, not struct tm **,
10840 so that the struct tm is saved in the critical section.
10841 All callers changed. Simplify allocation of initial buffer, partly
10842 motivated by the fact that memory allocation needs to be outside
10843 the critical section.
10845 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
10847 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
10848 with RESET_INTERVAL.
10850 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
10851 Remove duplicated buffer name initialization.
10853 2012-05-02 Jim Meyering <jim@meyering.net>
10855 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
10857 * xfns.c (x_window): Use xstrdup (Bug#11375).
10859 2012-05-02 Eli Zaretskii <eliz@gnu.org>
10861 * xdisp.c (pos_visible_p): If already at a newline from the
10862 display string before the 'while' loop, don't walk back the glyphs
10863 from it3.glyph_row. Solves assertion violation when the display
10864 string begins with a newline (egg.el). (Bug#11367)
10866 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
10868 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
10871 2012-05-01 Glenn Morris <rgm@gnu.org>
10873 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
10874 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
10875 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
10876 All were removed before 23.1.
10878 * dispnew.c: Remove HAVE_LIBNCURSES test;
10879 it is always true on relevant platforms.
10881 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
10882 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
10884 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
10886 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
10888 * .gdbinit (xpr): Remove checks for no longer existing misc types.
10889 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
10892 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
10894 Do not avoid creating empty evaporating overlays (Bug#9642).
10895 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
10896 That is, do not delete an evaporating overlay if it becomes
10897 empty after its bounds are adjusted to fit within its buffer.
10898 This fix caused other problems, and I'm reverting it until we get
10899 to the bottom of them.
10901 2012-04-27 Chong Yidong <cyd@gnu.org>
10903 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
10905 2012-04-27 Eli Zaretskii <eliz@gnu.org>
10907 * xdisp.c (pos_visible_p): If the window start position is beyond
10908 ZV, start the display from buffer beginning. Prevents assertion
10909 violation in init_iterator when the minibuffer window is scrolled
10910 via the scroll bar.
10912 * window.c (window_scroll_pixel_based): Likewise.
10914 2012-04-27 Chong Yidong <cyd@gnu.org>
10916 * keymap.c (where_is_internal): Doc fix (Bug#10872).
10918 2012-04-27 Glenn Morris <rgm@gnu.org>
10920 * fileio.c (Fcopy_file, Fset_file_selinux_context):
10921 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
10923 2012-04-27 Eli Zaretskii <eliz@gnu.org>
10925 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
10926 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
10928 2012-04-26 Eli Zaretskii <eliz@gnu.org>
10930 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
10931 display element, check also the underlying string or buffer
10932 character. (Bug#11341)
10934 * w32menu.c: Include w32heap.h.
10935 (add_menu_item): If the call to AppendMenuW (via
10936 unicode_append_menu) fails, disable Unicode menus only if we are
10937 running on Windows 9X/Me.
10939 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
10941 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
10942 (xgetint): Add missing shift for LSB tags.
10944 2012-04-24 Martin Rudalics <rudalics@gmx.at>
10946 * keyboard.c (read_char): Don't wipe echo area for select window
10947 events: These might get delayed via `mouse-autoselect-window'
10950 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
10952 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
10953 manipulation of :loaded-from data.
10955 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
10957 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
10958 now a cons (bug#11311).
10960 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
10962 Do not create empty overlays with the evaporate property (Bug#9642).
10963 * buffer.c (Fmove_overlay): Delete an evaporating overlay
10964 if it becomes empty after its bounds are adjusted to fit within
10965 its buffer. Without this fix, in a nonempty buffer (let ((o
10966 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
10967 yields an empty overlay that has the evaporate property, which is
10968 not supposed to happen.
10970 Fix minor GTK3 problems found by static checking.
10971 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
10972 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
10973 (struct _EmacsFixedClass, emacs_fixed_get_type):
10974 Move decls here from emacsgtkfixed.h, since they needn't be public.
10975 (emacs_fixed_get_type): Now static.
10976 (emacs_fixed_class_init): Omit unused local.
10977 (emacs_fixed_child_type): Remove; unused.
10978 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
10979 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
10980 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
10981 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
10982 (EMACS_FIXED_GET_CLASS): Remove; unused.
10983 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
10985 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
10986 Problem reported by Juanma Barranquero for Windows -Wunused-function.
10988 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
10990 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
10991 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
10992 (__malloc_size_t, __malloc_ptrdiff_t):
10993 Remove. All uses removed, replaced by the definiens if needed,
10994 since we can assume C89 or better now.
10995 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

11001 (_free, _realloc, _free_internal_nolock, _free_internal, free, cfree)
11002 (special_realloc, _realloc_internal_nolock, _realloc_internal)
11003 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
11004 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
11005 Define using prototypes, not old style.
11006 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
11007 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
11008 (align): Don't assume that signed integer overflow wraps around.
11009 Omit unused local var.
11010 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
11011 (_free_internal_nolock, memalign, mallochook, reallochook):
11012 Omit no-longer-needed casts.
11013 (valloc): Use getpagesize, not __getpagesize.
11014 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
11015 (struct hdr): The 'magic' member is now size_t, not unsigned long.
11017 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
11019 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
11021 Move functions from C to Lisp. Make non-blocking method calls
11022 the default. Implement further D-Bus standard interfaces.
11024 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.

11040 (xd_signature, xd_append_arg): Allow float for integer types.
11041 (xd_get_connection_references): New function.
11042 (xd_get_connection_address): Rename from xd_initialize.
11043 Return cached address.
11044 (xd_remove_watch): Do not unset $DBUS_SESSION_BUS_ADDRESS.
11045 (xd_close_bus): Rename from Fdbus_close_bus. Not needed on Lisp
11047 (Fdbus_init_bus): New optional arg PRIVATE. Cache address.
11048 Return number of refcounts.
11049 (Fdbus_get_unique_name): Make stronger parameter check.
11050 (Fdbus_message_internal): New defun.
11051 (Fdbus_call_method, Fdbus_call_method_asynchronously)
11052 (Fdbus_method_return_internal, Fdbus_method_error_internal)
11053 (Fdbus_send_signal, Fdbus_register_service)
11054 (Fdbus_register_signal, Fdbus_register_method): Move to dbus.el.

11064 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
11066 Fix GC_MALLOC_CHECK debugging output on 64-bit hosts.
11067 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
11068 Do not assume ptrdiff_t is the same width as 'int'.
11070 * alloc.c: Handle unusual debugging option combinations.
11071 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
11072 since the two debugging options are incompatible.
11073 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
11075 (mem_init, mem_insert, mem_insert_fixup):
11076 Define if GC_MARK_STACK || GC_MALLOC_CHECK.
11077 (NEED_MEM_INSERT): Remove; no longer needed.
11079 2012-04-22 Leo Liu <sdl.web@gmail.com>

11083 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
11085 * sysdep.c [__FreeBSD__]: Minor cleanups.
11086 (list_system_processes, system_process_attributes) [__FreeBSD__]:
11087 Use Emacs indenting style more consistently. Avoid some casts.
11088 Use 'double' consistently rather than mixing 'float' and 'double'.

11092 * sysdep.c (list_system_processes, system_process_attributes):
11093 Add implementation for FreeBSD (Bug#5243).

11099 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
11101 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
11102 It is never used otherwise.
11104 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
11106 * print.c (print_preprocess): Only check print_depth if print-circle
11108 (print_object): Check for cycles even when print-circle is nil and
11109 print-gensym is t, but only check print_depth if print-circle is nil.
11111 2012-04-20 Chong Yidong <cyd@gnu.org>
11113 * process.c (wait_reading_process_output): If EIO occurs on a pty,
11114 set the status to "failed" and ensure that sentinel is run.
11116 2012-04-20 Glenn Morris <rgm@gnu.org>
11118 * process.c (Fset_process_inherit_coding_system_flag)
11119 (Fset_process_query_on_exit_flag): Doc fix (mention return value).
11120 (Fmake_network_process, Fmake_serial_process): Doc fix.

11127 row, return zero immediately.
11128 (try_cursor_movement): If inside continuation line, don't back up
11129 farther than the first row after the header line, if any.
11130 Don't consider the header-line row as "partially visible", even if
11131 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
11133 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
11135 * lread.c (lisp_file_lexically_bound_p): Fix hang at ";-*-\n"

11142 * Makefile.in (C_WARNINGS_SWITCH): Remove.
11143 (WARN_CFLAGS, WERROR_CFLAGS): New macros.
11144 (ALL_CFLAGS): Use new macros rather than old.
11145 * process.c: Ignore -Wstrict-overflow to work around GCC bug 52904.
11146 * regex.c: Ignore -Wstrict-overflow. If !emacs, also ignore
11147 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
11148 -Wunused-result, -Wunused-variable. This should go away once
11149 the Emacs and Gnulib regex code is merged.
11150 (xmalloc, xrealloc): Now static.
11152 2012-04-17 Paul Eggert <eggert@cs.ucla.edu>

11169 New extern decls, to avoid calling undeclared functions.
11170 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
11171 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
11172 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
11173 (NEED_MEM_INSERT): New macro.
11174 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
11175 Remove one incorrect comment and fix another.

11183 Improve ralloc.c interface checking.
11184 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
11185 * buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)
11186 (r_alloc_free) [REL_ALLOC]: Move decls from here ...
11187 * lisp.h (r_alloc, r_alloc_free, r_re_alloc, r_alloc_reset_variable)

11189 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
11190 Remove decls. This fixes an "It stinks!".
11192 * alloc.c (which_symbols): Fix alignment issue / type clash.
11194 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
11196 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
11197 (struct Lisp_Misc_Any): Likewise.
11198 (struct Lisp_Free): Likewise.
11199 * alloc.c (union aligned_Lisp_Symbol): Define.

11207 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
11209 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
11210 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
11211 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
11212 * s/netbsd.h, s/sol2-6.h:
11213 Remove definition of GC_MARK_STACK, since the default now works.
11214 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
11215 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
11216 no longer the default.
11217 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
11219 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
11221 * lread.c (lisp_file_lexically_bound_p):
11222 Fix hang at ";-*-\n" (bug#11238).
11224 2012-04-14 Eli Zaretskii <eliz@gnu.org>
11226 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
11227 "unchanged" if its end.pos is beyond ZV. (Bug#11199)

11236 * s/cygwin.h (PTY_OPEN): Don't try to close a bogus file descriptor.
11238 2012-04-13 Reuben Thomas <rrt@sc3d.org>
11240 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
11242 2012-04-11 Daniel Colascione <dancol@dancol.org>
11244 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
11245 against is gone. It's better to use vfork now so that when Cygwin
11246 gains a new, working vfork, we use it automatically (bug#10398).
11248 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
11250 * window.c (save_window_save): Obey window-point-insertion-type.

11266 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
11268 * w32.c (w32_delayed_load): Record the full path of the library
11269 being loaded (bug#10424).
11271 2012-04-09 Glenn Morris <rgm@gnu.org>
11273 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
11274 not just in the obarray, before snarfing them. (Bug#11036)
11276 * Makefile.in ($(leimdir)/leim-list.el):
11277 Pass EMACS rather than BUILT_EMACS.
11279 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
11281 * process.c (make_process):
11282 * process.h: Add integer `gnutls_handshakes_tried' member to
11285 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.

11288 * gnutls.c (gnutls_log_function2i): Convenience log function.
11289 (emacs_gnutls_read): Use new log functions,
11290 `gnutls_handshakes_tried' process member, and
11291 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
11292 attempts per process (connection).
11294 2012-04-09 Chong Yidong <cyd@gnu.org>
11296 * eval.c (Fuser_variable_p, user_variable_p_eh)
11297 (lisp_indirect_variable): Functions deleted.
11298 (Fdefvar): Caller changed.
11300 * callint.c (Finteractive, Fcall_interactively):
11301 * minibuf.c (Fread_variable): Callers changed.
11303 2012-04-09 Eli Zaretskii <eliz@gnu.org>
11305 * xdisp.c (set_cursor_from_row): If the display string appears in
11306 the buffer at position that is closer to point than the position
11307 after the display string, display the cursor on the first glyph of
11308 the display string. Fixes cursor display when a 'display' text
11309 property immediately follows invisible text. (Bug#11094)
11311 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
11313 composite.c: use 'double' consistently
11314 * composite.c (get_composition_id): Use 'double' consistently
11315 instead of converting 'float' to 'double' and vice versa; this is
11316 easier to understand and avoids a GCC warning.
11318 2012-04-09 Glenn Morris <rgm@gnu.org>
11320 * Makefile.in: Generate leim-list with bootstrap-emacs, in
11321 preparation for dumping it with emacs. (Bug#4789)
11322 (leimdir): New variable.
11323 ($(leimdir)/leim-list.el): New rule.
11324 (emacs$(EXEEXT)): Depend on leim-list.el.

11342 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
11343 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
11344 (mark_memory): Mark Lisp_Objects only if pointers might hide in
11345 objects, as mark_maybe_pointer will catch them otherwise.
11346 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
11347 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

11354 2012-04-07 Eli Zaretskii <eliz@gnu.org>
11356 Support building on MS-Windows with libxml2.
11358 * makefile.w32-in (OBJ2): Add xml.$(O).
11359 (GLOBAL_SOURCES): Add xml.c.
11360 ($(BLD)/xml.$(O)): New dependency list.
11362 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
11363 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
11364 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
11365 [!WINDOWSNT]: New macros.
11366 (init_libxml2_functions, libxml2_loaded_p): New functions.
11367 (parse_region): Call fn_xmlCheckVersion instead of using the macro
11368 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
11369 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
11370 Calls xmlCleanupParser only if libxml2 was loaded (or statically
11372 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
11373 Call init_libxml2_functions before calling libxml2 functions.
11374 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
11376 * emacs.c: Don't include libxml/parser.h.
11377 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
11378 xmlCleanupParser directly.
11380 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
11382 2012-04-07 Eli Zaretskii <eliz@gnu.org>
11384 * indent.c (Fvertical_motion): If there is a display string at
11385 point, use it.vpos to compute how many lines to backtrack after
11386 move_it_to point. (Bug#11133)
11388 2012-04-06 Eli Zaretskii <eliz@gnu.org>
11390 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
11391 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
11392 about subtle differences between FETCH_CHAR* and STRING_CHAR*
11393 macros related to unification of CJK characters. For the details,
11394 see the discussion following the message here:
11395 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
11397 2012-04-04 Chong Yidong <cyd@gnu.org>
11399 * keyboard.c (Vdelayed_warnings_list): Doc fix.
11401 2012-04-01 Eli Zaretskii <eliz@gnu.org>
11403 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
11404 instead of alloca. (Bug#11138)
11406 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
11408 * w32menu.c (is_simple_dialog): Properly check lisp types.
11411 2012-03-31 Eli Zaretskii <eliz@gnu.org>
11413 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
11414 position we get to after a call to move_it_to fails the
11415 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
11416 only if we wind up in a string from display property. (Bug#11063)
11418 * window.c (Fdelete_other_windows_internal): Invalidate the row
11419 and column information about mouse highlight, so that redisplay
11420 restores it after reallocating the glyph matrices. (Bug#7464)
11422 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
11423 string comes from a `display' text property, use the buffer
11424 position of that property as if we actually saw that position in
11426 (move_it_by_lines): Remove the assertion that
11427 "it->current_x == 0 && it->hpos == 0" which can be legitimately
11428 violated when there's a before-string at the beginning of a line.
11431 2012-03-30 Eli Zaretskii <eliz@gnu.org>
11433 * xdisp.c (append_space_for_newline): If the default face was
11434 remapped, use the remapped face for the appended newline.
11435 (extend_face_to_end_of_line): Use the remapped default face for
11436 extending the face to the end of the line.
11437 (display_line): Call extend_face_to_end_of_line when the default
11438 face was remapped. (Bug#11068)
11440 2012-03-29 Eli Zaretskii <eliz@gnu.org>
11442 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
11444 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
11446 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
11448 2012-03-27 Glenn Morris <rgm@gnu.org>
11450 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
11453 2012-03-26 Kenichi Handa <handa@m17n.org>

11460 * keyboard.c (Vselection_inhibit_update_commands): New variable.
11461 (command_loop_1): Use it; inhibit selection update for
11462 handle-select-window too (Bug#8996).

11466 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
11468 2012-03-25 Kenichi Handa <handa@m17n.org>
11470 * dispextern.h (struct glyph): Change the bit length of
11471 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
11473 2012-03-24 Eli Zaretskii <eliz@gnu.org>
11475 * s/ms-w32.h (tzname): Include time.h before redirecting to
11476 _tzname. Fixes the MSVC build. (Bug#9960)

11480 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
11483 * xterm.c (XTread_socket): Only modify handling_signal if
11484 !SYNC_INPUT. (Bug#11080)
11486 2012-03-23 Eli Zaretskii <eliz@gnu.org>
11488 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
11489 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
11490 when fetching a multibyte character consumes more bytes than
11491 CHAR_BYTES returns, due to unification of CJK characters in
11492 string_char. (Bug#11073)
11494 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
11496 * process.c (wait_reading_process_output): Handle pty disconnect
11497 by refraining from sending oneself a SIGCHLD (bug#10933).
11499 2012-03-22 Chong Yidong <cyd@gnu.org>
11501 * dispextern.h (struct it): New member string_from_prefix_prop_p.
11503 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
11504 Mark string as coming from a prefix property.
11505 (handle_face_prop): Use default face for prefix strings (Bug#4281).
11506 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
11508 2012-03-21 Chong Yidong <cyd@gnu.org>
11510 * xfaces.c (Vface_remapping_alist): Doc fix.
11512 2012-03-20 Eli Zaretskii <eliz@gnu.org>
11514 * w32proc.c (Fw32_set_console_codepage)
11515 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):

11526 it fit in a valid range (Bug#11003).
11528 2012-03-18 Eli Zaretskii <eliz@gnu.org>
11530 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
11531 that is not from display property, accept the row as a "cursor
11532 row" if one of the string's character has a non-nil `cursor'
11533 property. Fixes cursor positioning when there are newlines in
11534 overlay strings, e.g. in icomplete.el. (Bug#11035)
11536 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
11538 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).

11567 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
11570 2012-03-03 Glenn Morris <rgm@gnu.org>
11572 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
11574 2012-03-02 Eli Zaretskii <eliz@gnu.org>

11577 position past the first glyph_row that ends at ZV. (Bug#10902)
11578 (redisplay_window, next_element_from_string): Fix typos in
11580 (redisplay_window): Pass to move_it_vertically the margin in

11585 * buffer.c (buffer-list-update-hook): Doc fix.
11587 2012-02-29 Eli Zaretskii <eliz@gnu.org>
11589 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
11590 push_it before setting up the iterator for the first overlay
11591 string, even if we have an empty string loaded.
11592 (next_overlay_string): If there's an empty string on the iterator
11593 stack, pop the stack. (Bug#10903)
11595 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
11597 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
11598 Suggested by Stefan Monnier in
11599 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
11600 * alloc.c (widen_to_Lisp_Object): New static function.
11601 (mark_memory): Also mark Lisp_Objects by fetching pointer words
11602 and widening them to Lisp_Objects. This would work even if
11603 USE_LSB_TAG is defined and wide integers are used, which might
11604 happen in a future version of Emacs.
11606 2012-02-25 Chong Yidong <cyd@gnu.org>
11608 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

11617 * keyboard.c (process_special_events): Handle all X selection
11618 requests in kbd_buffer, not just the next one (Bug#8869).
11620 2012-02-23 Chong Yidong <cyd@gnu.org>
11622 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
11623 call when setting menu-bar-lines and tool-bar-lines parameters.
11624 (unwind_create_frame_1): New helper function.
11626 * window.c (inhibit_window_configuration_change_hook): New var.

11645 when computing $valmask.
11647 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
11648 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
11649 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
11650 It's useless in that case, and it can cause problems on hosts
11651 that allocate halves of EMACS_INT values separately.
11652 Reported by Dan Horák. Diagnosed by Andreas Schwab in
11653 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
11654 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
11655 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
11656 it avoids undefined behavior on hosts where shifting right by more
11657 than the word width has undefined behavior.
11659 2012-02-19 Chong Yidong <cyd@gnu.org>
11661 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
11662 (Funhandled_file_name_directory, Ffile_name_as_directory)
11663 (Fdirectory_file_name, Fexpand_file_name)
11664 (Fsubstitute_in_file_name): Protect against invalid file handler
11665 return values (Bug#10845).

11681 2012-02-15 Chong Yidong <cyd@gnu.org>
11683 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is

11699 2012-02-12 Chong Yidong <cyd@gnu.org>
11701 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
11702 as that creates a dangerous corner case.
11704 * window.c (Fdelete_window_internal): Invalidate the mouse
11705 highlight (Bug#9904).
11707 2012-02-12 Glenn Morris <rgm@gnu.org>

11714 (Fx_selection_owner_p, Fx_get_selection_internal):
11715 Sync docs and argument specs with the xselect.c versions.
11717 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>

11737 2012-02-07 Chong Yidong <cyd@gnu.org>
11739 * buffer.c (Fbuffer_local_variables)
11740 (buffer_lisp_local_variables): Handle unbound vars correctly;
11741 don't let Qunbound leak into Lisp.
11743 2012-02-07 Glenn Morris <rgm@gnu.org>
11745 * image.c (Fimagemagick_types): Doc fix.
11747 * image.c (imagemagick-render-type): Change it from a lisp object
11748 to an integer. Move the doc here from the lisp manual.

11778 before BEGV. (Bug#10696)
11780 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
11782 Handle overflow when computing char display width (Bug#9496).
11783 * character.c (char_width): Return EMACS_INT, not int.
11784 (char_width, c_string_width): Check for overflow when
11785 computing the width; this is possible now that individual
11786 characters can have unbounded width. Problem introduced
11787 by merge from Emacs 23 on 2012-01-19.

11811 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
11813 (x_produce_glyphs): If the component of a composition is a null

11818 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
11819 first 2 arguments are identical. This makes inserting large
11820 output from a subprocess an order of magnitude faster on
11821 MS-Windows, where all sbrk'ed memory is always contiguous.

11921 DISP_STRING, and accept any glyph in a row whose object is that
11922 string as eligible for mouse highlight. Fixes mouse highlight of
11923 display strings from overlays. (Bug#10464)
11925 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>

11929 (Fmake_directory_internal): Use it.

12274 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
12275 verifies glyph row's hash code--we have just reallocated the

12440 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
12441 is set, removing the need for VIRT_ADDRESS_VARIES.
12442 (PURE_P): Use a more-efficient implementation that needs just one

12445 to 4 (xorl, subq, cmpq, setbe).
12446 * alloc.c (pure): Always extern now, since that's the

12457 (erase_phys_cursor, update_window_cursor, show_mouse_face)
12458 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
12459 behave as if the cursor position were at the window margin.
12461 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
12462 and the cursor position is out of bounds, behave as if the cursor
12463 position were at the window margin. (Bug#10075)
12465 2011-11-18 Chong Yidong <cyd@gnu.org>
12467 * window.c (Fwindow_combination_limit): Make first argument

12486 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
12488 * xdisp.c (row_hash): New function, body extracted from
12489 compute_line_metrics.
12490 (compute_line_metrics): Call row_hash, instead of computing the
12493 * dispnew.c (verify_row_hash): Call row_hash for computing the
12494 hash code of a row, instead of duplicating code from xdisp.c.

12950 an error. Set process slots as soon as we allocate them.
12952 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
12954 2011-10-27 Chong Yidong <cyd@gnu.org>
12956 * gnutls.c (emacs_gnutls_deinit): New function.
12957 Deallocate credentials structures as well as calling gnutls_deinit.
12958 (Fgnutls_deinit, Fgnutls_boot): Use it.
12960 * process.c (make_process): Initialize GnuTLS credentials to NULL.
12961 (deactivate_process): Call emacs_gnutls_deinit.
12963 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
12965 * image.c (x_create_x_image_and_pixmap):
12966 * w32.c (sys_rename, w32_delayed_load):
12967 * w32font.c (fill_in_logfont):
12968 * w32reg.c (x_get_string_resource): Silence compiler warnings.
12970 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
12972 * w32fns.c (w32_default_color_map): New function,
12973 extracted from Fw32_default_color_map.
12974 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
12976 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
12978 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
12980 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
12982 * keyboard.c (test_undefined): New function (bug#9751).
12983 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
12985 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
12987 * sysdep.c (init_sys_modes): Fix the check for the controlling
12988 terminal (Bug#6649).
12990 2011-10-20 Eli Zaretskii <eliz@gnu.org>
12992 * dispextern.h (struct bidi_it): New member next_en_type.
12994 * bidi.c (bidi_line_init): Initialize the next_en_type member.
12995 (bidi_resolve_explicit_1): When next_en_pos is valid for the
12996 current character, check also for next_en_type being WEAK_EN.
12997 (bidi_resolve_weak): Don't enter the expensive loop if the current
12998 position is before next_en_pos. Record the bidi type of the first
12999 non-ET, non-BN character we find, in addition to its position.
13000 (bidi_level_of_next_char): Invalidate next_en_type when
13001 next_en_pos is over-stepped.
13003 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
13005 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
13006 * editfns.c: Rewrite current-time-zone so that it invokes
13007 the equivalent of (format-time-string "%Z") to get the time zone name.
13008 This fixes a bug when the time zone name contains characters that
13009 need converting from the system time locale to Emacs internal format.
13010 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
13011 that patch fixed format-time-string to do the conversion, but
13012 I forgot to fix current-time-zone.
13013 (format_time_string): New function, containing most of
13014 what Fformat_time_string used to contain.
13015 (Fformat_time_string): Rewrite in terms of format_time_string.
13016 This doesn't change this function's behavior.
13017 (current-time-zone): Rewrite to use format_time_string.
13018 This fixes the bug reported by Michael Schierl in
13019 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
13020 Jason Rumney's 2007-06-07 change worked around this bug, but
13022 * systime.h (tzname, timezone): Remove no-longer-used declarations.
13024 2011-10-19 Eli Zaretskii <eliz@gnu.org>
13026 * xdisp.c (start_display): If the character at POS is displayed
13027 via a display vector, reset IT->current.dpvec_index to zero.
13028 (try_window_reusing_current_matrix): If a line ends in a display
13029 vector or the next line starts in a display vector, continue
13030 redrawing the window even though the character position of
13031 start_row was reached.
13034 2011-10-18 Chong Yidong <cyd@gnu.org>
13036 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
13037 with nobreak-char-display too.
13039 2011-10-18 Eli Zaretskii <eliz@gnu.org>
13041 Fix part 3 of bug#9771.
13042 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
13043 (bidi_resolve_neutral): Don't enter the expensive loop looking for
13044 non-neutral characters if the current character is a paragraph
13045 separator (a.k.a. Newline). This avoids running the same
13046 expensive loop twice, once when we consume the preceding newline
13047 and the other time when the line actually needs to be displayed.
13048 Avoid the loop when we see neutrals on the base embedding level
13049 following a character whose directionality is the same as the
13050 paragraph's. This avoids running the expensive loop when a line
13051 ends in a long sequence of neutrals, like control characters.
13052 Add assertion against STRONG_AL type. Slightly rearrange code
13053 that determines the type of a neutral given the first non-neutral
13055 (bidi_level_of_next_char): Set next_en_pos to zero when
13056 invalidating its info.
13058 2011-10-17 Eli Zaretskii <eliz@gnu.org>
13060 * xdisp.c (push_display_prop): Determine whether to record string
13061 or buffer position by IT->string, not by IT->method. Allow
13062 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
13063 (move_it_vertically_backward): Don't look for character position
13064 immediately after the newline when in a continuation line.
13067 2011-10-15 Martin Rudalics <rudalics@gmx.at>
13069 * window.c (coordinates_in_window): Rewrite and delabelize
13070 vertical border check. (Bug#5357) (Bug#9618)
13072 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
13074 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
13075 errors in XSetWindowBorder (bug#9310).
13077 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
13079 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
13080 avoid crash when xmalloc overrun checking is enabled.
13082 2011-10-13 Eli Zaretskii <eliz@gnu.org>
13084 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
13085 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
13086 cursor motion with <left> and <right> arrow keys.
13088 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
13089 some callers set that themselves.
13091 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13093 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
13094 display string and the previous row comes from the same string and
13095 is empty. (Bug#9739) (Bug#9738)
13097 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
13099 * doc.c (get_doc_string): Encode file name (bug#9735).
13101 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13103 * bidi.c (bidi_level_of_next_char):
13104 * xdisp.c (get_visually_first_element): Remove old incorrect
13105 comments regarding the Unicode Line Separator character.
13107 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
13109 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
13111 * alloc.c (Fgc_status): Do not access beyond zombies array
13112 boundary if nzombies > MAX_ZOMBIES.
13113 * alloc.c (dump_zombies): Add missing format specifier.
13115 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
13117 * xdisp.c (set_cursor_from_row): Simplify conditionals,
13118 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
13120 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
13121 Some packages use them to denote characters with modifiers.
13123 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
13125 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
13126 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
13127 matching a pp-number. Rename parameter var to var1.
13129 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
13131 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
13133 2011-10-08 Glenn Morris <rgm@gnu.org>
13135 * callint.c (Fcall_interactively): Give a more explicit error for the
13136 'c' case with a non-character input. (Bug#8479)
13138 2011-10-08 Eli Zaretskii <eliz@gnu.org>
13140 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
13142 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
13143 lines that are hscrolled on the left.
13145 * dispnew.c (buffer_posn_from_coords): Account for a possible
13146 presence of header-line. (Bug#4426)
13148 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
13150 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
13151 Don't advertise functionality which we discourage or doesn't work.
13153 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
13155 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
13156 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
13157 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
13158 this makes Emacs dump core during garbage collection on rare
13159 occasions. sizeof is obviously inferior to offsetof here, so
13160 stick with offsetof.
13161 (GC_POINTER_ALIGNMENT): New macro.
13162 (mark_memory): Omit 3rd (offset) arg; caller changed.
13163 Don't assume EMACS_INT alignment is the same as pointer alignment.
13165 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
13167 * keyboard.c (read_key_sequence_remapped): New var.
13168 (read_key_sequence): Compute remapping in the right buffer.
13169 (command_loop_1): Use read_key_sequence's remapping directly.
13171 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
13173 * dired.c (file_name_completion): Don't expand file name.
13174 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
13175 before checking file name handler.
13177 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
13178 they've been requested explicitly (bug#9591).
13180 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
13182 * keymap.c (Fsingle_key_description): Use make_specified_string
13183 instead of build_string to build string from push_key_description.
13186 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13188 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
13189 This fixes a Y2038 bug on 64-bit hosts.
13190 * buffer.c (reset_buffer):
13191 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
13192 (Fclear_buffer_auto_save_failure):
13193 Use 0, not -1, to represent an unset failure time, since time_t
13194 might not be signed.
13196 Remove dependency on glibc malloc internals.
13197 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13198 Move back here from lisp.h, but with their new implementations.
13199 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13200 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
13201 * charset.c (charset_table_init): New static var.
13202 (syms_of_charset): Use it instead of xmalloc. This removes a
13203 dependency on glibc malloc internals. See Eli Zaretskii's comment in
13204 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
13205 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13206 Move back to alloc.c.
13207 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13208 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
13210 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
13212 * nsterm.m (windowDidResize): Call x_set_window_size only when
13213 ns_in_resize is true. Otherwise set pixelwidth/height and
13214 call change_frame_size (Bug#9628).
13216 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13218 Port --enable-checking=all to Fedora 14 x86-64.
13219 * charset.c (syms_of_charset): Also account for glibc malloc's
13220 internal overhead when calculating the initial malloc maximum.
13222 Port --enable-checking=all to Fedora 14 x86.
13223 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13225 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
13226 (overrun_check_realloc, overrun_check_free):
13227 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
13228 That way, xmalloc returns a properly-aligned pointer even if
13229 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
13230 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
13231 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
13232 into account when calculating the initial malloc maximum.
13233 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13234 Move here from alloc.c, so that charset.c can use it too.
13235 Properly align; the old code wasn't right for common 32-bit hosts
13236 when configured with --enable-checking=all.
13237 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13238 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
13240 2011-09-29 Eli Zaretskii <eliz@gnu.org>
13242 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
13245 2011-09-28 Eli Zaretskii <eliz@gnu.org>
13247 * xdisp.c (compute_display_string_end): If there's no display
13248 string at CHARPOS, return -1.
13250 * bidi.c (bidi_fetch_char): When compute_display_string_end
13251 returns a negative value, treat the character as a normal
13252 character not covered by a display string. (Bug#9624)
13254 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
13256 * lread.c (Fread_from_string): Fix typo in docstring.
13258 2011-09-27 Eli Zaretskii <eliz@gnu.org>
13260 * xdisp.c (handle_invisible_prop): If invisible text ends on a
13261 newline, reseat the iterator instead of bidi-iterating there one
13262 character at a time. (Bug#9610)
13263 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
13264 TO_CHARPOS if the bidi iterator is at base embedding level.
13266 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
13268 * lread.c (readevalloop): Use correct code for NBSP.
13269 (read1): Likewise. (Bug#9608)
13271 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
13273 * dbusbind.c (Fdbus_register_signal): When service is not
13274 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
13276 2011-09-25 Glenn Morris <rgm@gnu.org>
13278 * buffer.c (truncate-lines): Doc fix.
13280 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
13282 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
13283 (Fset_window_next_buffers): Doc fix.
13285 2011-09-24 Glenn Morris <rgm@gnu.org>
13287 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
13289 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
13291 Fix minor problems found by static checking.
13292 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
13293 * indent.c (Fvertical_motion): Fix == vs = typo.
13295 2011-09-24 Eli Zaretskii <eliz@gnu.org>
13297 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
13298 Default value is now t. Doc fix.
13300 * indent.c (Fvertical_motion): Compute and apply the overshoot
13301 logic when moving up, not only when moving down. Fix the
13302 confusing name and values of the it_overshoot_expected variable;
13303 logic changes accordingly. (Bug#9254) (Bug#9549)
13305 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
13306 CHARPOS is covered by a display string which includes newlines.
13307 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
13308 is covered by a display string with embedded newlines.
13310 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
13312 * dbusbind.c (Fdbus_register_signal): Add match rule to
13313 Vdbus_registered_objects_table. (Bug#9581)
13314 (Fdbus_register_method, Vdbus_registered_objects_table):
13317 2011-09-24 Jim Meyering <meyering@redhat.com>
13319 do not ignore write error for any output size
13320 The previous change was incomplete.
13321 While it makes emacs --batch detect the vast majority of stdout
13322 write failures, errors were still ignored whenever the output size is
13323 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
13324 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
13325 && echo FAIL: ignored write error
13326 FAIL: ignored write error
13327 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
13328 && echo FAIL: ignored write error
13329 FAIL: ignored write error
13330 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
13332 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
13334 * emacs.c (Fkill_emacs): In noninteractive mode exit
13335 non-successfully if a write error occurred on stdout. (Bug#9574)
13337 2011-09-21 Eli Zaretskii <eliz@gnu.org>
13339 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
13342 * dispextern.h (struct it): Update the comment documenting what
13345 2011-09-20 Eli Zaretskii <eliz@gnu.org>
13347 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
13348 a display string, extend search for cursor position to end of row.
13349 (find_row_edges): If the row ends in a newline from a display
13350 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
13351 Handle the case of a display string with multiple newlines.
13352 (Fcurrent_bidi_paragraph_direction): Fix search for previous
13353 non-empty line. Fixes confusing cursor motion with arrow keys at
13354 the beginning of a line that starts with whitespace.
13356 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
13358 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
13361 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
13363 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
13364 boolean (Bug#9154).
13366 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13368 * xdisp.c (display_line): Record maximum and minimum buffer
13369 positions even if no glyphs were produced (e.g., by a zero-width
13370 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
13371 buffer positions that will be removed from the glyph row because
13373 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
13374 column is beyond frame width: don't subtract 1 "pixel" when
13375 computing width of the stretch.
13376 (reseat_at_next_visible_line_start): Undo the change made on
13377 2011-09-17 that saved paragraph information and restored it after
13378 the call to `reseat'. (Bug#9545)
13380 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13382 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
13383 and turn window cursor on if cleared (Bug#9415).
13385 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
13387 * search.c (boyer_moore): Take unibyte characters from pattern
13388 literally. (Bug#9458)
13390 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13392 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
13394 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
13396 Fix minor problem found by static checking.
13397 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
13398 initialized, to pacify gcc -Wuninitialized.
13400 * fileio.c: Report proper errno when syscall falls.
13401 (Finsert_file_contents): Save and restore errno,
13402 so that report_file_error outputs the correct diagnostic.
13403 (Fwrite_region) [CLASH_DETECTION]: Likewise.
13405 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13407 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
13409 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13411 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
13412 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
13414 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13416 * xdisp.c (reseat_at_next_visible_line_start): Keep information
13417 about the current paragraph and restore it after the call to reseat.
13419 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
13420 (bidi_find_paragraph_start): Search back for paragraph beginning
13421 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
13422 (bidi_move_to_visually_next): Only trigger paragraph-related
13423 computations when the last character is a newline or at EOB, not
13424 just any NEUTRAL_B. (Bug#9470)
13426 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
13427 truncated lines if point is covered by a display string. (Bug#9524)
13429 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
13431 * xselect.c: Relax test for outgoing X longs (Bug#9498).
13432 (cons_to_x_long): New function.
13433 (lisp_data_to_selection_data): Use it. Correct the test for
13434 short-versus-long data; it was negated. Break out of vector
13435 loop, for efficiency, when a long datum is discovered.
13437 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
13439 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
13441 2011-09-16 Eli Zaretskii <eliz@gnu.org>
13443 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
13444 GCC PR/17406) by declaring this function with external scope.
13446 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13448 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
13449 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
13451 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
13453 * editfns.c (Fformat): Correctly handle text properties on "%%".
13455 2011-09-15 Eli Zaretskii <eliz@gnu.org>
13457 * xterm.c (x_draw_composite_glyph_string_foreground):
13458 * w32term.c (x_draw_composite_glyph_string_foreground):
13459 * term.c (encode_terminal_code):
13460 * composite.c (composition_update_it, get_composition_id):
13461 * xdisp.c (get_next_display_element)
13462 (fill_composite_glyph_string): Add comments about special meaning
13463 of TAB characters in a composition.
13465 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13467 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
13468 This occurs when processing a multibyte format.
13469 Problem reported by Wolfgang Jenker.
13471 2011-09-15 Johan Bockgård <bojohan@gnu.org>
13473 * xdisp.c (try_cursor_movement): Only check for exact match if
13474 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
13476 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13478 Remove unused external symbols.
13479 * dispextern.h (calc_pixel_width_or_height): Remove decl.
13480 * xdisp.c (calc_pixel_width_or_height): Now static.
13481 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
13482 * indent.c (check_display_width):
13483 * w32term.c: Fix comment to match code.
13484 * xterm.c, xterm.h (x_catching_errors): Remove.
13486 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13488 * xselect.c: Use signed conversions more consistently (Bug#9498).
13489 (selection_data_to_lisp_data): Assume incoming selection data are
13490 signed integers, not unsigned. This is to be consistent with
13491 outgoing selection data, which was modified to use signed integers
13492 in as part of the fix to Bug#9196 in response to Jan D.'s comment
13493 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
13494 expects long, not unsigned long.
13496 2011-09-14 Eli Zaretskii <eliz@gnu.org>
13498 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
13499 computation of loop end. Reported by Johan Bockgård
13502 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
13504 * frame.c (Fother_visible_frames_p): Function deleted.
13506 2011-09-12 Eli Zaretskii <eliz@gnu.org>
13508 * indent.c (compute_motion): Process display vector front to back
13509 rather than the other way around. (Bug#2496)
13511 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
13513 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
13515 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
13517 * minibuf.c (Fread_from_minibuffer): Doc fix.
13519 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13521 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
13522 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
13524 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
13526 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
13527 value for non-existent files.
13529 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13531 * fileio.c (Finsert_file_contents): If the file cannot be opened,
13532 set its "size" to -1. This will set the modtime_size field of
13533 the corresponding buffer to -1, which is what
13534 verify-visited-file-modtime expects for files that do not exist.
13537 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
13539 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
13541 * lisp.h: ... from here. push_key_description is no longer
13542 defined in keyboard.c, so its declaration should not be in
13543 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
13544 logically belongs with push_key_description.
13546 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
13548 * buffer.h: Include <sys/types.h> instead of <time.h>.
13549 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
13550 Problem reported by Herbert J. Skuhra.
13552 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
13554 * xml.c (parse_region): Make the parsing work for
13555 non-comment-starting XML files again (bug#9144).
13557 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
13559 * image.c (gif_load): Fix calculation of bottom and right corner.
13562 2011-09-10 Eli Zaretskii <eliz@gnu.org>
13564 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
13565 redisplay in small windows.
13567 2011-09-09 Eli Zaretskii <eliz@gnu.org>
13569 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
13571 2011-09-08 Martin Rudalics <rudalics@gmx.at>
13573 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
13574 Operate on live windows only.
13576 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
13578 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
13580 2011-09-07 Eli Zaretskii <eliz@gnu.org>
13582 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
13583 only under bidi iteration.
13585 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
13587 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
13589 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13591 isnan: Fix porting problem to Solaris 10 with bundled gcc.
13592 Without this fix, the command to link temacs failed due to an
13593 undefined symbol __builtin_isnan. This is because
13594 /usr/include/iso/math_c99.h #defines isnan(x) to
13595 __builtin_isnan(x), but the bundled gcc, which identifies itself
13596 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
13598 * floatfns.c (isnan): #undef, and then #define to a clone of
13600 (Fisnan): Always define, since it's always available now.
13601 (syms_of_floatfns): Always define isnan at the Lisp level.
13603 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13605 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
13607 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13609 * fileio.c: Fix bugs with large file offsets (Bug#9428).
13610 The previous code assumed that file offsets (off_t values) fit in
13611 EMACS_INT variables, which is not true on typical 32-bit hosts.
13612 The code messed up by falsely reporting buffer overflow in cases
13613 such as (insert-file-contents "big" nil 1 2) into an empty buffer
13614 when "big" contains more than 2**29 bytes, even though this
13615 inserts just one byte and does not overflow the buffer.
13616 (Finsert_file_contents): Store file offsets as off_t
13617 values, not as EMACS_INT values. Check for overflow when
13618 converting between EMACS_INT and off_t. When checking for
13619 buffer overflow or for overlap, take the offsets into account.
13620 Don't use EMACS_INT for small values where int suffices.
13621 When checking for overlap, fix a typo: ZV was used where
13622 ZV_BYTE was intended.
13623 (Fwrite_region): Don't assume off_t fits into 'long'.
13624 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
13626 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
13628 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
13630 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13632 sprintf-related integer and memory overflow issues (Bug#9412).
13634 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
13635 (esprintf, exprintf, evxprintf): New functions.
13636 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
13637 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
13638 (modify_event_symbol): Do not assume that the length of
13639 name_alist_or_stem is safe to alloca and fits in int.
13640 (Fexecute_extended_command): Likewise for function name and binding.
13641 (Frecursion_depth): Wrap around reliably on integer overflow.
13642 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
13643 since some callers pass EMACS_INT values.
13644 (Fsingle_key_description): Don't crash if symbol name contains more
13645 than MAX_ALLOCA bytes.
13646 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
13647 (get_minibuffer): Arg is now EMACS_INT, not int.
13648 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
13649 (esprintf, exprintf, evxprintf): New decls.
13650 * window.h (command_loop_level, minibuf_level): Reflect API changes.
13652 * dbusbind.c (signature_cat): New function.
13653 (xd_signature, Fdbus_register_signal):
13654 Do not overrun buffer; instead, report string overflow.
13656 * dispnew.c (add_window_display_history): Don't overrun buffer.
13657 Truncate instead; this is OK since it's just a log.
13659 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
13660 even if the time zone offset is outlandishly large.
13661 Don't mishandle offset == INT_MIN.
13663 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
13664 when creating daemon; the previous buffer-overflow check was incorrect.
13666 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
13667 which has the guts of the old verror function.
13669 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
13670 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
13672 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
13673 (font_unparse_xlfd): Don't blindly alloca long strings.
13674 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
13675 fits in int, when using sprintf. Use single snprintf to count
13676 length of string rather than counting it via multiple sprintfs;
13677 that's simpler and more reliable.
13678 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
13679 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
13680 sprintf, in case result does not fit in int.
13682 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
13683 (fontset_from_font): Print it.
13685 * frame.c (tty_frame_count): Now printmax_t, not int.
13686 (make_terminal_frame, set_term_frame_name): Print it.
13687 (x_report_frame_params): In X, window IDs are unsigned long,
13688 not signed long, so print them as unsigned.
13689 (validate_x_resource_name): Check for implausibly long names,
13690 and don't assume name length fits in 'int'.
13691 (x_get_resource_string): Don't blindly alloca invocation name;
13692 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
13695 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
13696 (xg_check_special_colors, xg_set_geometry):
13697 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
13699 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
13700 Use esprintf, not sprintf, in case result does not fit in int.
13702 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13703 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
13704 it as a large positive number.
13705 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
13706 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13708 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
13709 in case result does not fit in int.
13711 * print.c (float_to_string): Detect width overflow more reliably.
13712 (print_object): Make sprintf buffer a bit bigger, to avoid potential
13713 buffer overrun. Don't assume list length fits in 'int'. Treat
13714 print length of 0 as 0, not as infinity; to be consistent with other
13715 uses of print length in this function. Don't overflow print length
13716 index. Don't assume hash table size fits in 'long', or that
13717 vectorlike size fits in 'unsigned long'.
13719 * process.c (make_process): Use printmax_t, not int, to format
13720 process-name gensyms.
13722 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
13724 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
13725 to avoid potential buffer overrun.
13727 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
13728 if X resource line is longer than 512 bytes.
13730 * xfns.c (x_window): Make sprintf buffer a bit bigger
13731 to avoid potential buffer overrun.
13733 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
13735 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
13737 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13739 Integer overflow fixes for scrolling, etc.
13740 Without these, Emacs silently mishandles large integers sometimes.
13741 For example, "C-u 4294967297 M-x recenter" was treated as if
13742 it were "C-u 1 M-x recenter" on a typical 64-bit host.
13744 * xdisp.c (try_window_id): Check Emacs fixnum range before
13745 converting to 'int'.
13747 * window.c (window_scroll_line_based, Frecenter):
13748 Check that an Emacs fixnum is in range before assigning it to 'int'.
13749 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
13750 values converted from Emacs fixnums.
13751 (Frecenter): Don't wrap around a line count if it is out of 'int'
13752 range; instead, treat it as an extreme value.
13753 (Fset_window_configuration, compare_window_configurations):
13754 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
13756 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
13757 that can exceed INT_MAX. Check that EMACS_INT value is in range
13758 before assigning it to the (possibly-narrower) index.
13759 (match_limit): Don't assume that a fixnum can fit in 'int'.
13761 * print.c (print_object): Use ptrdiff_t, not int, for index that can
13764 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
13765 (Fvertical_motion): Don't wrap around LINES values that don't fit
13766 in 'int'. Instead, treat them as extreme values. This is good
13767 enough for windows, which can't have more than INT_MAX lines anyway.
13769 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
13771 * Require libxml/parser.h to avoid compilation warning.
13773 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
13775 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
13776 since this reportedly can destroy thread storage.
13778 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
13780 * syntax.c (find_defun_start): Update all cache variables if
13781 exiting early (Bug#9401).
13783 2011-08-30 Eli Zaretskii <eliz@gnu.org>
13785 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
13787 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
13788 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
13789 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
13791 * term.c (tty_append_glyph): New function.
13792 (produce_stretch_glyph): Static function and its prototype deleted.
13794 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
13797 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
13799 * image.c (parse_image_spec): Check for nonnegative, not for positive,
13800 when checking :margin (Bug#9390).
13801 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
13802 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
13803 so that the name doesn't mislead. All uses changed.
13805 2011-08-28 Johan Bockgård <bojohan@gnu.org>
13807 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
13810 2011-08-27 Eli Zaretskii <eliz@gnu.org>
13812 * xdisp.c (move_it_to): Don't bail out early when reaching
13813 position beyond to_charpos, if we are scanning backwards.
13814 (move_it_vertically_backward): When DY == 0, make sure we get to
13815 the first character in the line after the newline.
13817 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
13819 * ccl.c: Improve and simplify overflow checking (Bug#9196).
13820 (ccl_driver): Do not generate an out-of-range pointer.
13821 (Fccl_execute_on_string): Remove unnecessary check for
13822 integer overflow, noted by Stefan Monnier in
13823 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
13824 Remove a FIXME that didn't need fixing.
13825 Simplify the newly-introduced buffer reallocation code.
13827 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
13829 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
13831 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
13833 Integer and memory overflow issues (Bug#9196).
13835 * doc.c (get_doc_string): Rework so that
13836 get_doc_string_buffer_size is the actual buffer size, rather than
13837 being 1 less than the actual buffer size; this makes xpalloc more
13840 * image.c (x_allocate_bitmap_record, cache_image):
13841 * xselect.c (Fx_register_dnd_atom):
13842 Simplify previous changes by using xpalloc.
13844 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
13845 since either will do and ptrdiff_t is convenient with xpalloc.
13847 * charset.c (charset_table_size)
13848 (struct charset_sort_data.priority): Now ptrdiff_t.
13849 (charset_compare): Don't overflow if priorities differ greatly.
13850 (Fsort_charsets): Don't assume list length fits in int.
13851 Check for size-calculation overflow when allocating sort data.
13852 (syms_of_charset): Allocate an initial charset table that is
13853 just under 64 KiB, to avoid problems with glibc malloc and mmap.
13855 * cmds.c (internal_self_insert): Check for size-calculation overflow.
13857 * composite.h (struct composition.glyph_len): Now int, not unsigned.
13858 The actual value is always <= INT_MAX, and leaving it unsigned made
13859 overflow checking harder.

13874 (region_cache_backward, pp_cache):
13875 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
13876 so that ptrdiff_t * can be passed to xpalloc.

13906 require adding more-complicated checks.
13908 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
13909 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.

13949 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
13951 * emacs.c (main): Do not reallocate argv, since there is a null at
13952 the end that can be overwritten, and this way there's no need to
13953 worry about size-calculation overflow.
13954 (sort_args): Check for size-calculation overflow.
13956 * eval.c (init_eval_once, grow_specpdl): Don't update size until

13963 (x_set_alpha): Do not assume XINT fits in int.
13965 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
13966 This is for the members text_lines, text_cols, total_lines, total_cols,
13967 where the system imposes an 'int' limit.

13976 Check for size-calculation overflow.
13977 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
13978 do, as we prefer signed integers.

14083 (X_LONG_MIN): New macros.
14084 Use them to make the following changes clearer.
14085 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.

14088 (SELECTION_QUANTUM): Remove, replacing with ...
14089 (selection_quantum): ... new function, which avoids overflow.
14091 (struct selection_data.size): Now ptrdiff_t, not int, to avoid

14109 Don't store size until memory allocation succeeds.
14110 (x_get_window_property): Plug memory leak on memory exhaustion.
14111 Don't double-block input; malloc is safe here. Don't assume 2**34
14112 - 4 fits in unsigned long. Add an xassert to check
14113 XGetWindowProperty overflow. Be more careful about overflow
14114 calculations, and distinguish size from memory overflow better.

14205 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
14206 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
14207 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
14208 length, not size_t. Use ptrdiff_t for index, not int.
14209 (keyremap_step, read_key_sequence): Redo bufsize check to avoid

14238 Prefer int to unsigned where either will do.
14239 (tiff_handler): New function, combining the cores of the
14240 old tiff_error_handler and tiff_warning_handler.

14242 stack buffer overflows. It uses only the features of vsnprintf
14243 that are common to both POSIX and native Microsoft.
14244 (tiff_error_handler, tiff_warning_handler): Use it.
14245 (tiff_load, gif_load, imagemagick_load_image):

14288 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
14289 buffers, return left-to-right.
14290 (set_cursor_from_row): Consider candidate row a win if its glyph
14291 represents a newline and point is on that newline. Fixes cursor
14292 positioning on the newline at EOL of R2L text within L2R
14293 paragraph, and vice versa.
14294 (try_cursor_movement): Check continued rows, in addition to
14295 continuation rows. Fixes unwarranted scroll when point enters a
14296 continued line of R2L text within an L2R paragraph, or vice versa.
14297 (cursor_row_p): Consider the case of point being equal to
14298 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
14299 from the end of a short line to the beginning of a continued line
14300 of R2L text within L2R paragraph.

14324 * xdisp.c (redisplay_window): When computing centering_position,
14325 account for the height of the header line. (Bug#8874)
14327 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
14328 instead of CHAR_TO_BYTE. Fixes a crash when a completion
14329 candidate is selected by the mouse, and that candidate has a
14330 composed character under the mouse.
14332 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
14333 coordinates reported by pos-visible-in-window-p for a composed
14334 character in column zero.
14336 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

14340 2011-08-22 Eli Zaretskii <eliz@gnu.org>
14342 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
14343 consider it a hit if to_charpos is anywhere in the range of the
14344 composed buffer positions.
14346 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
14348 * image.c (gif_load): Don't assume that each subimage has the same
14349 dimensions as the base image. Handle disposal method that is
14350 "undefined" by the gif spec (Bug#9335).
14352 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
14354 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
14355 (Fcondition_case): Document `debug' symbol in error handler.
14357 2011-08-19 Eli Zaretskii <eliz@gnu.org>
14359 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
14360 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
14361 from an Org mode buffer to a Speedbar frame.
14363 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
14364 a composition, take its buffer position from IT->cmp_it.charpos.
14365 Fixes cursor positioning at the beginning of a line that begins
14366 with a composed character.
14368 2011-08-18 Eli Zaretskii <eliz@gnu.org>
14370 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
14371 character bidirectional type, use STRONG_L instead. Fixes crashes
14372 in a buffer produced by `describe-categories'.
14374 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
14375 members before the level stack, so they would be saved and
14376 restored when copying iterator state. Fixes incorrect reordering
14377 around TABs covered by display properties.
14379 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
14381 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

14386 (internal_condition_case_2, internal_condition_case_n):
14387 Remove unnecessary aborts (Bug#9081).
14389 2011-08-17 Eli Zaretskii <eliz@gnu.org>
14391 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
14392 has no `load' handler, try opening the file locally. (Bug#9311)

14451 * xdisp.c (move_it_in_display_line_to): Don't invoke
14452 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
14453 ppos_it. Fixes vertical cursor motion when line beginning is
14454 covered by an image. (Bug#9296)
14456 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>

14463 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
14464 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
14465 the event loop. Get status from as_status (Bug#7276).
14467 * nsterm.m (sendEvent): If event is NSApplicationDefined and
14468 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
14469 the event loop (Bug#7276).
14471 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
14473 * gnutls.c (QCgnutls_bootprop_priority)

14495 (Fnetwork_interface_list): Allocate in increments of bytes instead
14496 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
14497 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
14499 (struct ifflag_def): notrailers is smart on OSX.
14500 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
14501 Get hardware address with getifaddrs if available.

14505 * xdisp.c (iterate_out_of_display_property): xassert that
14506 IT->position is set to within IT->object's boundaries. Break from
14507 the loop as soon as EOB is reached; avoids infloops in redisplay
14508 when IT->position is set up wrongly due to some bug.
14509 Set IT->current to match the bidi iterator unconditionally.
14510 (push_display_prop): Allow GET_FROM_STRING as IT->method on
14511 entry. Force push_it to save on the stack the current
14512 buffer/string position, to be restored by pop_it. Fix flags in
14513 the iterator structure wrt the object coming from a display
14514 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
14515 properties. (Bug#9284)
14517 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
14519 * fontset.c (fontset_get_font_group): Add proper type checks.

14558 longlines-mode. (Bug#9254)
14559 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
14560 word-wrap under bidirectional display. (Bug#9224)
14562 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
14563 is non-zero, even if the data buffer is NULL. Fixes a crash in
14564 vertical-motion with longlines-mode. (Bug#9254)
14566 2011-08-05 Eli Zaretskii <eliz@gnu.org>
14568 * bidi.c <bidi_cache_total_alloc>: Now static.

14571 * xdisp.c (display_line): Release buffer allocated for shelved bidi
14574 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
14575 amount allocated this far in `bidi_cache_total_alloc'.
14576 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
14577 non-zero, only free the data buffer without restoring the cache
14578 contents. All callers changed.
14580 * dispextern.h (bidi_unshelve_cache): Update prototype.
14582 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
14583 (move_it_in_display_line, move_it_to)
14584 (move_it_vertically_backward, move_it_by_lines): Replace the call
14585 to xfree to an equivalent call to bidi_unshelve_cache.
14586 (move_it_in_display_line_to): Fix logic of returning
14587 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)

14643 DISP_PROP_P, and pass it to compute_display_string_pos.
14644 Only handle text covered by a display string if DISP_PROP_P is returned
14645 non-zero. All callers of bidi_fetch_char changed.
14647 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>

14733 'malloc' might be invoked reentrantly.
14735 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
14736 In other words, assume that every image size is allowed, on non-X

14761 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
14762 (bidi_find_other_level_edge):
14763 Use ptrdiff_t instead of EMACS_INT where either will do.
14764 This works better on 32-bit hosts configured --with-wide-int.
14765 (bidi_cache_ensure_space): Check for size-calculation overflow.
14766 Use % rather than repeated addition, for better worst-case speed.
14767 Don't set bidi_cache_size until after xrealloc returns, because it
14769 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
14770 (bidi_cache_ensure_space): Also check that the bidi cache size
14771 does not exceed that of the largest Lisp string or buffer. See Eli
14772 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
14774 * alloc.c (__malloc_size_t): Remove.
14775 All uses replaced by size_t. See Andreas Schwab's note
14776 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
14778 * image.c: Improve checking for integer overflow.
14779 (check_image_size): Assume that f is nonnull, since
14780 it is always nonnull in practice. This is one less thing to
14781 worry about when checking for integer overflow later.
14782 (x_check_image_size): New function, which checks for integer
14783 overflow issues inside X.
14784 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
14785 This removes the need for a memory_full check.
14786 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
14787 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
14788 (xbm_read_bitmap_data): Change locals back to 'int', since
14789 their values must fit in 'int'.
14790 (xpm_load_image, png_load, tiff_load):
14791 Invoke x_create_x_image_and_pixmap earlier,
14792 to avoid much needless work if the image is too large.
14793 (tiff_load): Treat overly large images as if
14794 x_create_x_image_and_pixmap failed, not as malloc failures.
14795 (gs_load): Use x_check_image_size.
14797 * gtkutil.c: Omit integer casts.
14798 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
14799 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
14801 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
14803 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
14804 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
14805 would wrongly return t on a 64-bit host.
14807 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
14808 The plain *_OVERFLOW macros run afoul of GCC bug 49705
14809 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
14810 and therefore cause GCC to emit a bogus diagnostic in some cases.
14812 * image.c: Integer signedness and overflow and related fixes.
14813 This is not an exhaustive set of fixes, but it's time to
14814 record what I've got.
14815 (lookup_pixel_color, check_image_size): Remove redundant decls.
14816 (check_image_size): Don't assume that arbitrary EMACS_INT values
14817 fit in 'int', or that arbitrary 'double' values fit in 'int'.
14818 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
14819 (tiff_load, imagemagick_load_image):
14820 Check for overflow in size calculations.
14821 (x_create_x_image_and_pixmap): Remove unnecessary test for
14822 xmalloc returning NULL; that can't happen.
14823 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
14824 (xpm_color_bucket): Use better integer hashing function.
14825 (xpm_cache_color): Don't possibly over-allocate memory.
14826 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
14827 (gif_memory_source):
14828 Use ptrdiff_t, not int or size_t, to record sizes.
14829 (png_load): Don't assume values greater than 2**31 fit in 'int'.
14830 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
14831 either works, as we prefer signed integers.
14832 (tiff_read_from_memory, tiff_write_from_memory):
14833 Return tsize_t, not size_t, since that's what the TIFF API wants.
14834 (tiff_read_from_memory): Don't fail simply because the read would
14835 go past EOF; instead, return a short read.
14836 (tiff_load): Omit no-longer-needed casts.
14837 (Fimagemagick_types): Don't assume size fits into 'int'.
14839 Improve hashing quality when configured --with-wide-int.
14840 * fns.c (hash_string): New function, taken from sxhash_string.
14841 Do not discard information about ASCII character case; this
14842 discarding is no longer needed.
14843 (sxhash-string): Use it. Change sig to match it. Caller changed.
14844 * lisp.h: Declare it.
14845 * lread.c (hash_string): Remove, since we now use fns.c's version.
14846 The fns.c version returns a wider integer if --with-wide-int is
14847 specified, so this should help the quality of the hashing a bit.
14849 * emacs.c: Integer overflow minor fix.
14850 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
14851 Define only if GNU_LINUX.
14852 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
14854 * dispnew.c: Integer signedness and overflow fixes.
14855 Remove unnecessary forward decls, that were a maintenance hassle.
14856 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
14858 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
14859 (scrolling_window): Use ptrdiff_t, not int, for byte count.
14860 (prepare_desired_row, line_draw_cost):
14861 Use int, not unsigned, where either works.
14862 (save_current_matrix, restore_current_matrix):
14863 Use ptrdiff_t, not size_t, where either works.
14864 (init_display): Check for overflow more accurately, and without
14865 relying on undefined behavior.
14867 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
14868 Remove, replacing with the new symbols in lisp.h. All uses changed.
14869 * fileio.c (make_temp_name):
14870 * filelock.c (lock_file_1, lock_file):
14871 * xdisp.c (message_dolog):
14872 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
14873 Use pMd etc. instead.
14874 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
14875 replacing the pWIDE etc. symbols removed from editfns.c.
14877 * keyboard.h (num_input_events): Now uintmax_t.
14878 This is (very slightly) less likely to mess up due to wraparound.
14881 * buffer.c: Integer signedness fixes.
14882 (alloc_buffer_text, enlarge_buffer_text):
14883 Use ptrdiff_t rather than size_t when either will do, as we prefer
14886 * alloc.c: Integer signedness and overflow fixes.
14887 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
14888 (__malloc_size_t): Default to size_t, not to int.
14889 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
14890 (Fgarbage_collect, mark_object_loop_halt, mark_object):
14891 Prefer ptrdiff_t to size_t when either would do, as we prefer
14893 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
14894 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
14895 Now const. Initialize with values that are in range even if char
14897 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
14898 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
14899 These functions do the right thing with sizes > 2**32.
14900 (check_depth): Now ptrdiff_t, not int.
14901 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
14902 Adjust to new way of storing sizes. Check for size overflow bugs
14904 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
14905 slightly wrong anyway, as it missed one instance of
14906 XMALLOC_OVERRUN_CHECK_OVERHEAD.
14907 (refill_memory_reserve): Omit needless cast to size_t.
14908 (mark_object_loop_halt): Mark as externally visible.
14910 * xselect.c: Integer signedness and overflow fixes.
14911 (Fx_register_dnd_atom, x_handle_dnd_message):
14912 Use ptrdiff_t, not size_t, since we prefer signed.
14913 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
14914 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
14915 x_dnd_atoms_size and x_dnd_atoms_length.
14917 * doprnt.c: Prefer signed to unsigned when either works.
14919 * doprnt.c (doprnt):
14921 * xdisp.c (vmessage):
14922 Use ptrdiff_t, not size_t, when using or implementing doprnt,
14923 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
14924 prefer signed arithmetic to avoid comparison confusion.
14925 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
14926 but is a bit tricky.
14928 Assume freestanding C89 headers, string.h, stdlib.h.
14929 * data.c, doprnt.c, floatfns.c, print.c:
14930 Include float.h unconditionally.
14931 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
14932 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
14933 * regex.c: Likewise for stddef.h, string.h.
14934 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
14935 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
14936 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
14937 (STDC_HEADERS): Remove obsolete defines.
14938 * sysdep.c: Include limits.h unconditionally.
14940 Assume support for memcmp, memcpy, memmove, memset.
14941 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
14942 * regex.c (memcmp, memcpy):
14943 Remove; we assume C89 now.
14945 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
14946 (__malloc_safe_bcopy): Remove; no longer needed.
14948 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
14949 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
14950 well either way, and we prefer signed to unsigned.
14952 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
14954 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
14955 closes the connection while we're reading (bug#9182).
14957 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
14959 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
14960 are specified (Bug#9168).
14962 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
14964 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
14965 Found by GCC static checking and --with-wide-int on a 32-bit host.
14967 2011-07-25 Eli Zaretskii <eliz@gnu.org>
14969 * xdisp.c (compute_display_string_pos): Fix logic of caching
14970 previous display string position. Initialize cached_prev_pos to
14971 -1. Fixes slow-down at the beginning of a buffer.
14973 2011-07-24 Eli Zaretskii <eliz@gnu.org>
14975 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
14976 for attrs[LFACE_FONTSET_INDEX].
14978 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
14980 * xml.c (parse_region): Remove unused local
14981 that was recently introduced.
14983 2011-07-23 Eli Zaretskii <eliz@gnu.org>
14985 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
14986 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
14988 * xdisp.c (move_it_in_display_line_to): Record the best matching
14989 position for TO_CHARPOS while scanning the line, and restore it on
14990 exit if none of the characters scanned was an exact match.
14991 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
14992 when exact match is impossible due to invisible text, and the
14993 lines are truncated.
14995 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
14997 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
15000 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15002 Fix a significant slow-down of cursor motion with C-n, C-p,
15003 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
15004 auto-repeat under bidi redisplay in fontified buffers.
15005 * xdisp.c (compute_stop_pos_backwards): New function.
15006 (next_element_from_buffer): Call compute_stop_pos_backwards to
15007 find a suitable prev_stop when we find ourselves before
15009 (reseat): Don't look for prev_stop, as that could mean a very long
15011 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
15012 <cached_disp_overlay_modiff>: Cache for last found display string
15014 (compute_display_string_pos): Return the cached position if asked
15015 about the same buffer in the same area of character positions, and
15016 the buffer wasn't changed since the time the display string
15017 position was cached.
15019 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15021 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
15022 is an integer, which is important for empty lines. (Bug#9149)
15024 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
15026 * frame.c (Fmodify_frame_parameters): In tty case, update the
15027 default face if necessary (Bug#4238).
15029 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
15031 * editfns.c (Fstring_to_char): No need to explain what a character
15032 is in the docstring (Bug#6576).
15034 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15036 * xml.c (parse_region): Make sure we always return a tree.
15038 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
15040 * xml.c (parse_region): If a document contains only comments,
15043 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15045 * xml.c (make_dom): Return comments, too.
15047 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
15050 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
15051 and the surrounding thread.
15052 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
15053 rather than fgets, and retry after EINTR. Otherwise, 'emacs
15054 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
15056 * s/openbsd.h (BROKEN_SIGIO): Define.
15057 * unexelf.c (unexec) [__OpenBSD__]:
15058 Don't update the .mdebug section of the Alpha COFF symbol table.
15060 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15062 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
15065 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
15067 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
15068 This fixes some race conditions on the permissions of any newly
15071 * alloc.c (valid_pointer_p): Use pipe, not open.
15072 This fixes some permissions issues when debugging.
15074 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
15075 If fchown fails to set both uid and gid, try to set just gid,
15076 as that is sometimes allowed. Adjust the file's mode to eliminate
15077 setuid or setgid bits that are inappropriate if fchown fails.
15079 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
15081 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
15082 to compare Lisp_Objects.
15083 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
15084 global_gnutls_log_level, don't mistake it for a Lisp_Object.
15085 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
15087 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
15089 * lread.c (read_integer): Unread even EOF character.
15090 (read1): Likewise. Properly record start position of symbol.
15092 * lread.c (read1): Read `#:' as empty uninterned symbol if no
15093 symbol character follows.
15095 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
15097 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
15098 This works around a problem with the previous change to Fcopy_file.
15099 Recent glibc declares fchown with __attribute__((warn_unused_result)),
15100 and without this change, GCC might complain about discarding
15101 fchown's return value.
15103 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
15105 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
15107 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
15109 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
15111 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
15113 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
15114 it's used from the C level.
15116 * process.c: Use the same condition for POLL_FOR_INPUT in both
15117 keyboard.c and process.c (bug#1858).
15119 2011-07-09 Lawrence Mitchell <wence@gmx.li>
15121 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
15122 (Fgnutls_boot): Use it.
15124 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
15126 * doc.c (Fsubstitute_command_keys): Revert last change.
15128 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
15130 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
15131 quotes the next character, and doesn't affect other longer
15132 sequences (bug#8935).
15134 * lread.c (syms_of_lread): Clarify that is isn't only
15135 `eval-buffer' and `eval-defun' that's affected by
15136 `lexical-binding' (bug#8460).
15138 2011-07-15 Eli Zaretskii <eliz@gnu.org>
15140 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
15141 bidi redisplay when a line includes both an image and is truncated.
15143 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
15145 Fix minor problems found by static checking.
15146 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
15147 (elsz): Now a signed constant, not a size_t var. We prefer signed
15148 types to unsigned, to avoid integer comparison confusion. Without
15149 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
15150 "cannot optimize loop, the loop counter may overflow", a symptom
15152 * indent.c (Fvertical_motion): Mark locals as initialized.
15153 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
15155 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
15157 * search.c (Fre_search_backward): Mention `case-fold-search' in
15158 all the re_search_* functions (bug#8138).
15160 * keyboard.c (Fopen_dribble_file): Document when the file is
15163 2011-07-14 Eli Zaretskii <eliz@gnu.org>
15165 * bidi.c (bidi_dump_cached_states): Fix format of displaying
15168 Support bidi reordering of display and overlay strings.
15169 * xdisp.c (compute_display_string_pos)
15170 (compute_display_string_end): Accept additional argument STRING.
15171 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
15172 (reseat_to_string): Initialize bidi_it->string.s and
15173 bidi_it->string.schars.
15174 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
15175 NULL (avoids a crash in bidi_paragraph_init).
15176 Initialize itb.string.lstring.
15177 (init_iterator): Call bidi_init_it only of a valid
15178 buffer position was specified. Initialize paragraph_embedding to
15180 (reseat_to_string): Initialize the bidi iterator.
15181 (display_string): If we need to ignore text properties of
15182 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
15183 original value of -1 will not work with bidi.)
15184 (compute_display_string_pos): First arg is now struct
15185 `text_pos *'; all callers changed. Support display properties on
15187 (compute_display_string_end): Support display properties on Lisp
15189 (init_iterator, reseat_1, reseat_to_string): Initialize the
15190 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
15191 when iterating on a string not from display properties).
15192 (compute_display_string_pos, compute_display_string_end):
15193 Fix calculation of the object to scan. Fixes an error when using
15195 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
15196 base_level_stop; instead, set base_level_stop to BEGV.
15197 Fixes crashes in vertical-motion.
15198 (next_element_from_buffer): Improve commentary for when

15677 (clone_per_buffer_values): Don't assume that

15679 This isn't true in general, and it's particularly not true
15680 if Emacs is configured with --with-wide-int.
15681 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
15682 New macros, used in the buffer.c change.

15718 Random fixes. E.g., (random) never returned negative values.
15719 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
15720 subseconds part to the entropy, as that's a bit more random.
15721 Prefer signed to unsigned, since the signedness doesn't matter and
15722 in general we prefer signed. When given a limit, use a
15723 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
15724 latter isn't right if USE_2_TAGS_FOR_INTS.
15725 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
15726 not 0..VALMASK. Don't discard "excess" bits that random () returns.

15730 * textprop.c (text_property_stickiness):
15731 Obey Vtext_property_default_nonsticky.

15738 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
15739 This is more efficient than Ffile_directory_p and avoids a minor race.
15741 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
15743 * buffer.c (Foverlay_put): Say what the return value is
15746 * fileio.c (barf_or_query_if_file_exists): Check first if the file
15747 is a directory before asking whether to use the file name
15749 (barf_or_query_if_file_exists): Make the "File is a directory"
15750 error be more correct.
15752 * fns.c (Frequire): Remove the mention of the .gz files, since
15753 that's installation-specific, but keep the mention of
15754 `get-load-suffixes'.

15764 (syms_of_gnutls): Remove duplicate DEFSYM for
15765 Qgnutls_bootprop_verify_hostname_error, an error for
15766 Qgnutls_bootprop_verify_error (which is no longer used).
15768 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
15769 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
15770 Also (re)move comments that are misplaced or no longer relevant.
15772 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15774 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

15833 (syms_of_keymap): Defsubr make-composed-keymap.
15834 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

15871 * eval.c (struct backtrace): Simplify and port the data structure.
15872 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
15873 signed bit field, as this assumption is not portable and it makes
15874 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
15875 "char debug_on_exit : 1" as this is not portable either; instead,
15876 use the portable "unsigned int debug_on_exit : 1". Remove unused
15877 member evalargs. Remove obsolete comments about cc bombing out.
15879 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

16076 * image.c (cache_image): Check for size arithmetic overflow.
16078 * lread.c: Integer overflow issues.
16079 (saved_doc_string_size, saved_doc_string_length)
16080 (prev_saved_doc_string_size, prev_saved_doc_string_length):
16081 Now ptrdiff_t, not int.
16082 (read1): Don't assume doc string length fits in int. Check for
16083 out-of-range doc string lengths.
16084 (read_list): Don't assume file position fits in int.
16085 (read_escape): Check for hex character overflow.
16087 2011-06-22 Leo Liu <sdl.web@gmail.com>
16089 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
16090 Move to minibuffer.el.
16092 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
16094 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
16095 The following patches are for when GLYPH_DEBUG && !XASSERT.
16096 * dispextern.h (trace_redisplay_p, dump_glyph_string):
16097 * dispnew.c (flush_stdout):
16098 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
16099 Mark as externally visible.
16100 * dispnew.c (check_window_matrix_pointers): Now static.
16101 * dispnew.c (window_to_frame_vpos):
16102 * xfns.c (unwind_create_frame):
16103 * xterm.c (x_check_font): Remove unused local.
16104 * scroll.c (CHECK_BOUNDS):
16105 * xfaces.c (cache_fache): Rename local to avoid shadowing.
16106 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
16107 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
16108 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
16109 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
16111 (debug_method_add): Use va_list and vsprintf rather than relying
16112 on undefined behavior with wrong number of arguments.
16113 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
16114 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
16115 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
16116 since we're not interested in debugging glyphs with old libraries.
16117 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
16118 GCC 4.6.0's static checking.
16120 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
16122 Integer overflow and signedness fixes (Bug#8873).

16131 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
16132 (x_create_bitmap_from_xpm_data):
16133 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
16134 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
16136 * xfaces.c (load_pixmap):
16137 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
16138 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
16139 (.bitmaps_last, struct x_output.icon_bitmap):
16140 Use ptrdiff_t, not int, for bitmap indexes.
16141 (x_allocate_bitmap_record): Check for size overflow.
16142 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
16144 Use ptrdiff_t, not int, for overlay counts.
16145 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
16146 * editfns.c (overlays_around, get_pos_property):
16147 * textprop.c (get_char_property_and_overlay):
16148 * xdisp.c (next_overlay_change, note_mouse_highlight):
16149 * xfaces.c (face_at_buffer_position):
16150 * buffer.c (OVERLAY_COUNT_MAX): New macro.
16151 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
16152 (Fnext_overlay_change, Fprevious_overlay_change)
16153 (mouse_face_overlay_overlaps, Foverlays_in):
16154 Use ptrdiff_t, not int, for sizes.
16155 (overlays_at, overlays_in): Check for size-calculation overflow.
16157 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
16159 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
16160 (x_session_initialize): Do not assume string length fits in int.
16162 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
16163 This is unlikely, but can occur if DPI is outlandish.
16165 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
16166 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
16168 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
16169 * xrdb.c (magic_file_p, search_magic_path):
16170 Omit last arg SUFFIX; it was always 0. All callers changed.
16171 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
16173 * xfont.c (xfont_match): Avoid need for strlen.
16175 * xfns.c: Don't assume strlen fits in int.
16176 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
16178 * xdisp.c (message_log_check_duplicate): Return intmax_t,
16179 not unsigned long, as we prefer signed integers. All callers changed.
16180 Detect integer overflow in repeat count.
16181 (message_dolog): Don't assume print length fits in 39 bytes.
16182 (display_mode_element): Don't assume strlen fits in int.
16184 * termcap.c: Don't assume sizes fit in int and never overflow.
16185 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
16186 (gobble_line): Check for size-calculation overflow.
16188 * minibuf.c (Fread_buffer):
16189 * lread.c (intern, intern_c_string):
16190 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
16191 Don't assume string length fits in int.
16193 * keyboard.c (parse_tool_bar_item):
16194 * gtkutil.c (style_changed_cb): Avoid need for strlen.
16196 * font.c: Don't assume string length fits in int.
16197 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
16198 Use ptrdiff_t, not int.
16199 (font_intern_prop): Don't assume string length fits in int.
16200 Don't assume integer property fits in fixnum.
16201 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
16203 * filelock.c: Fix some buffer overrun and integer overflow issues.
16204 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
16205 Reformulate so as not to need the command string.
16206 Invoke gzip -cd rather than gunzip, as it's more portable.
16207 (lock_info_type, lock_file_1, lock_file):
16208 Don't assume pid_t and time_t fit in unsigned long.
16209 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
16210 (current_lock_owner): Prefer signed type for sizes.
16211 Use memcpy, not strncpy, where memcpy is what is really wanted.
16212 Don't assume (via atoi) that time_t and pid_t fit in int.
16213 Check for time_t and/or pid_t out of range, e.g., via a network share.
16214 Don't alloca where an auto var works fine.
16216 * fileio.c: Fix some integer overflow issues.
16217 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
16218 Don't assume string length fits in int.
16219 (directory_file_name): Don't assume string length fits in long.
16220 (make_temp_name): Don't assume pid fits in int, or that its print
16221 length is less than 20.
16223 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
16225 * coding.c (make_subsidiaries): Don't assume string length fits in int.
16227 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
16229 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
16230 We prefer signed integers, even for size calculations.
16232 * emacs.c: Don't assume string length fits in 'int'.
16233 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
16234 (main): Don't invoke strlen when not needed.
16236 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
16237 (XD_DEBUG_MESSAGE): Don't waste a byte.
16239 * callproc.c (getenv_internal_1, getenv_internal)
16240 (Fgetenv_internal):
16241 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
16243 * lread.c (invalid_syntax): Omit length argument.
16244 All uses changed. This doesn't fix a bug, but it simplifies the
16245 code away from its former Hollerith-constant appearance, and it's
16246 one less 'int' to worry about when looking at integer-overflow issues.
16247 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
16249 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
16250 This didn't break anything, but it didn't help either.
16251 It's confusing to put a bogus integer in a place where the actual
16252 value does not matter.
16253 (LIST_END_P): Remove unused macro and its bogus comment.
16254 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
16256 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
16257 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
16259 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
16260 We prefer signed types, and the value cannot exceed the EMACS_INT
16261 range anyway (because otherwise the length would not be representable).
16262 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
16263 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
16264 This avoids a GCC warning when WIDE_EMACS_INT.
16266 * indent.c (sane_tab_width): New function.
16267 (current_column, scan_for_column, Findent_to, position_indentation)
16268 (compute_motion): Use it. This is just for clarity.
16269 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
16271 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
16273 * lisp.h (lint_assume): New macro.
16274 * composite.c (composition_gstring_put_cache):
16275 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
16277 * editfns.c, insdel.c:
16278 Omit unnecessary forward decls, to simplify future changes.
16280 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
16282 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
16284 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
16285 Use much-faster test for byte-length change.
16286 Don't assume string byte-length fits in 'int'.
16287 Check that character arg fits in 'int'.
16288 (mapcar1): Declare byte as byte, for clarity.
16290 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
16292 * fns.c (concat): Catch string overflow earlier.
16293 Do not rely on integer wraparound.
16295 * dispextern.h (struct it.overlay_strings_charpos)
16296 (struct it.selective): Now EMACS_INT, not int.
16297 * xdisp.c (forward_to_next_line_start)
16298 (back_to_previous_visible_line_start)
16299 (reseat_at_next_visible_line_start, next_element_from_buffer):
16300 Don't arbitrarily truncate the value of 'selective' to int.
16302 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
16304 * composite.c: Don't truncate sizes to 'int'.
16305 (composition_gstring_p, composition_reseat_it)
16306 (composition_adjust_point): Use EMACS_INT, not int.
16307 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
16308 not EMACS_UINT, for indexes.
16310 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
16312 * buffer.c: Include <verify.h>.
16313 (struct sortvec.priority, struct sortstr.priority):
16314 Now EMACS_INT, not int.
16315 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
16316 (struct sortstr.size, record_overlay_string)
16317 (struct sortstrlist.size, struct sortlist.used):
16318 Don't truncate size to int.
16319 (record_overlay_string): Check for size-calculation overflow.
16320 (init_buffer_once): Check at compile-time, not run-time.
16322 2011-06-22 Jim Meyering <meyering@redhat.com>
16324 Don't leak an XBM-image-sized buffer
16325 * image.c (xbm_load): Free the image buffer after using it.
16327 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
16330 * composite.c (find_automatic_composition): Omit needless 'return 0;'
16331 that Sun C diagnosed.
16332 * fns.c (secure_hash): Fix pointer signedness issue.
16333 * intervals.c (static_offset_intervals): New function.
16334 (offset_intervals): Use it.
16336 2011-06-21 Leo Liu <sdl.web@gmail.com>
16339 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
16342 * fns.c (secure_hash): Rename from crypto_hash_function and change
16343 the first arg to accept symbols.
16344 (Fsecure_hash): New primitive.
16345 (syms_of_fns): New symbols.
16347 2011-06-20 Deniz Dogan <deniz@dogan.se>
16349 * process.c (Fset_process_buffer): Clarify return value in
16352 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
16354 * dispnew.c (add_window_display_history): Use BVAR.
16356 * xdisp.c (debug_method_add): Use BVAR.
16357 (check_window_end, dump_glyph_matrix, dump_glyph)
16358 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
16360 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
16363 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
16364 check till after the cache is created in init_frame_faces.
16366 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
16368 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
16370 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
16372 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
16373 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
16374 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
16376 Improve buffer-overflow checking (Bug#8873).
16377 * fileio.c (Finsert_file_contents):
16378 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
16379 Remove the old (too-loose) buffer overflow checks.
16380 They weren't needed, since make_gap checks for buffer overflow.
16381 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
16382 The old code merely checked for Emacs fixnum overflow, and relied
16383 on undefined (wraparound) behavior. The new code avoids undefined
16384 behavior, and also checks for ptrdiff_t and/or size_t overflow.
16386 * editfns.c (Finsert_char): Don't dump core with very negative counts.
16387 Tune. Don't use wider integers than needed. Don't use alloca.
16388 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
16390 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
16392 * insdel.c, lisp.h (buffer_overflow): New function.
16393 (insert_from_buffer_1, replace_range, replace_range_2):
16394 * insdel.c (make_gap_larger):
16395 * editfns.c (Finsert_char):
16396 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
16398 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
16400 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
16402 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
16404 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
16405 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
16407 * fileio.c: Don't assume EMACS_INT fits in off_t.
16408 (emacs_lseek): New static function.
16409 (Finsert_file_contents, Fwrite_region): Use it.
16410 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
16412 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
16414 * fns.c: Don't overflow int when computing a list length.
16415 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
16416 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
16417 truncation on 64-bit hosts. Check for QUIT every
16418 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
16419 faster and is responsive enough.
16420 (Flength): Report an error instead of overflowing an integer.
16421 (Fsafe_length): Return a float if the value is not representable
16422 as a fixnum. This shouldn't happen except in contrived situations.
16423 (Fnthcdr, Fsort): Don't assume list length fits in int.
16424 (Fcopy_sequence): Don't assume vector length fits in int.
16426 * alloc.c: Check that resized vectors' lengths fit in fixnums.
16427 (header_size, word_size): New constants.
16428 (allocate_vectorlike): Don't check size overflow here.
16429 (allocate_vector): Check it here instead, since this is the only
16430 caller of allocate_vectorlike that could cause overflow.
16431 Check that the new vector's length is representable as a fixnum.
16433 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
16434 The previous code was bogus. For example, next_almost_prime (32)
16435 returned 39, which is undesirable as it is a multiple of 3; and
16436 next_almost_prime (24) returned 25, which is a multiple of 5 so
16437 why was the code bothering to check for multiples of 7?
16439 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
16441 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
16443 Variadic C functions now count arguments with ptrdiff_t.
16444 This partly undoes my 2011-03-30 change, which replaced int with size_t.
16445 Back then I didn't know that the Emacs coding style prefers signed int.
16446 Also, in the meantime I found a few more instances where arguments
16447 were being counted with int, which may truncate counts on 64-bit
16448 machines, or EMACS_INT, which may be unnecessarily wide.
16449 * lisp.h (struct Lisp_Subr.function.aMANY)
16450 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
16451 Arg counts are now ptrdiff_t, not size_t.
16452 All variadic functions and their callers changed accordingly.
16453 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
16454 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
16455 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
16456 * callint.c (Fcall_interactively): Check arg count for overflow,
16457 to avoid potential buffer overrun. Use signed char, not 'int',
16458 for 'varies' array, so that we needn't bother to check its size
16459 calculation for overflow.
16460 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
16461 * eval.c (apply_lambda):
16462 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
16463 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
16464 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
16466 * callint.c (Fcall_interactively): Don't use index var as event count.
16468 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
16469 * mem-limits.h (SIZE): Remove; no longer used.
16471 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
16473 Remove unnecessary casts.
16474 * xterm.c (x_term_init):
16475 * xfns.c (x_set_border_pixel):
16476 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
16477 These aren't needed now that we assume ANSI C.
16479 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
16480 It's more likely to cause problems (due to unsigned overflow)
16483 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
16485 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
16487 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
16489 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
16491 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
16493 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
16495 GLYPH_CODE_FACE returns EMACS_INT, not int.
16496 * dispextern.h (merge_faces):
16497 * xfaces.c (merge_faces):
16498 * xdisp.c (get_next_display_element, next_element_from_display_vector):
16499 Don't assume EMACS_INT fits in int.
16501 * character.h (CHAR_VALID_P): Remove unused parameter.
16502 * fontset.c, lisp.h, xdisp.c: All uses changed.
16504 * editfns.c (Ftranslate_region_internal): Omit redundant test.
16506 * fns.c (concat): Minor tuning based on overflow analysis.
16507 This doesn't fix any bugs. Use int to hold character, instead
16508 of constantly refetching from Emacs object. Use XFASTINT, not
16509 XINT, for value known to be a character. Don't bother comparing
16510 a single byte to 0400, as it's always less.
16512 * floatfns.c (Fexpt):
16513 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
16515 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
16518 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
16520 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
16521 Without this fix, on a 64-bit host (aset S 0 4294967386) would
16522 incorrectly succeed when S was a string, because 4294967386 was
16523 truncated before it was used.
16525 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
16526 Otherwise, an out-of-range integer could cause undefined behavior
16529 * composite.c: Use int, not EMACS_INT, for characters.
16530 (fill_gstring_body, composition_compute_stop_pos): Use int, not
16531 EMACS_INT, for values that are known to be in character range.
16532 This doesn't fix any bugs but is the usual style inside Emacs and
16533 may generate better code on 32-bit machines.
16535 Make sure a 64-bit char is never passed to ENCODE_CHAR.
16536 This is for reasons similar to the recent CHAR_STRING fix.
16537 * charset.c (Fencode_char): Check that character arg is actually
16538 a character. Pass an int to ENCODE_CHAR.
16539 * charset.h (ENCODE_CHAR): Verify that the character argument is no
16540 wider than 'int', as a compile-time check to prevent future regressions
16543 * character.c (char_string): Remove unnecessary casts.
16545 Make sure a 64-bit char is never passed to CHAR_STRING.
16546 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
16547 by silently ignoring the top 32 bits, allowing some values
16548 that were far too large to be valid characters.
16549 * character.h: Include <verify.h>.
16550 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
16551 arguments are no wider than unsigned, as a compile-time check
16552 to prevent future regressions in this area.
16554 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
16555 (Fsubst_char_in_region):
16557 * xdisp.c (decode_mode_spec_coding):
16558 Adjust to CHAR_STRING's new requirement.
16559 * editfns.c (Finsert_char, Fsubst_char_in_region):
16560 * fns.c (concat): Check that character args are actually
16561 characters. Without this test, these functions did the wrong
16562 thing with wildly out-of-range values on 64-bit hosts.
16564 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
16565 These casts should not be needed on 32-bit hosts, either.
16566 * keyboard.c (read_char):
16567 * lread.c (Fload): Remove casts to unsigned.
16569 * lisp.h (UNSIGNED_CMP): New macro.
16570 This fixes comparison bugs on 64-bit hosts.
16571 (ASCII_CHAR_P): Use it.
16572 * casefiddle.c (casify_object):
16573 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
16574 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
16575 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
16576 * dispextern.h (FACE_FROM_ID):
16577 * keyboard.c (read_char): Use UNSIGNED_CMP.
16579 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
16580 not to EMACS_INT, to avoid GCC warning.
16582 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
16584 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
16585 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
16586 isn't needed on 32-bit machines.
16588 * buffer.c (Fgenerate_new_buffer_name):
16589 Use EMACS_INT for count, not int.
16590 (advance_to_char_boundary): Return EMACS_INT, not int.
16592 * data.c (Qcompiled_function): Now static.
16594 * window.c (window_body_lines): Now static.
16596 * image.c (gif_load): Rename local to avoid shadowing.
16598 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
16599 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
16600 * alloc.c (make_save_value): Integer argument is now of type
16601 ptrdiff_t, not int.
16602 (mark_object): Use ptrdiff_t, not int.
16603 * lisp.h (pD): New macro.
16604 * print.c (print_object): Use it.
16606 * alloc.c: Use EMACS_INT, not int, to count objects.
16607 (total_conses, total_markers, total_symbols, total_vector_size)
16608 (total_free_conses, total_free_markers, total_free_symbols)
16609 (total_free_floats, total_floats, total_free_intervals)
16610 (total_intervals, total_strings, total_free_strings):
16611 Now EMACS_INT, not int. All uses changed.
16612 (Fgarbage_collect): Compute overall total using a double, so that
16613 integer overflow is less likely to be a problem. Check for overflow
16614 when converting back to an integer.
16615 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
16616 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
16617 These were 'int' variables that could overflow on 64-bit hosts;
16618 they were never used, so remove them instead of repairing them.
16619 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
16620 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
16621 Previously, this ceilinged at INT_MAX, but that doesn't work on
16623 (allocate_pseudovector): Don't use EMACS_INT when int would do.
16625 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
16626 (allocate_vectorlike): Check for ptrdiff_t overflow.
16627 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
16628 when a (possibly-narrower) signed value would do just as well.
16629 We prefer using signed arithmetic, to avoid comparison confusion.
16631 * alloc.c: Catch some string size overflows that we were missing.
16632 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
16633 for convenience in STRING_BYTES_MAX.
16634 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
16635 The definition here is exact; the one in lisp.h was approximate.
16636 (allocate_string_data): Check for string overflow. This catches
16637 some instances we weren't catching before. Also, it catches
16638 size_t overflow on (unusual) hosts where SIZE_MAX <= min
16639 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
16640 and ptrdiff_t and EMACS_INT are both 64 bits.
16642 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
16643 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
16644 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
16646 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
16648 * alloc.c (Fmake_string): Check for out-of-range init.
16650 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
16652 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
16654 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
16656 * xfns.c (x_set_scroll_bar_default_width): Remove argument to

16667 and height if HAVE_GTK3 (Bug#8505).
16668 (scroll_bar_width_for_theme): New variable.
16669 (update_theme_scrollbar_width): New function.
16670 (xg_get_default_scrollbar_width): Move code to
16671 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.

16674 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
16676 * emacsgtkfixed.c, emacsgtkfixed.h: New files.

16683 * window.c (temp_output_buffer_show): Call display_buffer with
16684 second argument Vtemp_buffer_show_specifiers and reset latter
16685 immediately after the call.
16686 (Vtemp_buffer_show_specifiers): New variable.
16687 (auto_window_vscroll_p, next_screen_context_lines)
16688 (Vscroll_preserve_screen_position): Remove leading asterisks from

17221 instead of using explicit *_CHAR codes.
17222 (bidi_resolve_explicit, bidi_resolve_weak):

17239 (display_prop_intangible_p): Reimplement to call
17240 handle_display_spec instead of single_display_spec_intangible_p.
17241 Accept 3 additional arguments needed by handle_display_spec.

17251 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
17252 value of a `display' property is a "replacing spec".
17253 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
17254 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

17282 All callers changed. (Bug#8762)
17284 * gnutls.c: Use Emacs's memory allocators.
17285 Without this change, the gnutls library would invoke malloc etc.
17286 directly, which causes problems on non-SYNC_INPUT hosts, and which
17287 runs afoul of improving memory_full behavior. (Bug#8761)
17288 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
17289 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
17290 xfree instead of the default malloc, realloc, free.
17291 (Fgnutls_boot): No need to check for memory allocation failure,
17292 since xmalloc does that for us.

17316 * alloc.c (allocate_vectorlike):
17317 Check for overflow in vector size calculations.
17318 * ccl.c (ccl_driver):
17319 Check for overflow when converting EMACS_INT to int.

17321 need to be updated by these changes.
17322 * fns.c (make_hash_table, maybe_resize_hash_table):
17323 Check for integer overflow with large hash tables.
17324 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
17325 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
17326 (SXHASH_REDUCE): New macro.
17327 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
17328 Use it instead of discarding useful hash info with large hash values.
17329 (sxhash_float): New function.
17330 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
17331 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
17332 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
17333 Rewrite to use FIXNUM_BITS, as this simplifies things.
17334 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
17335 Adjust signatures to match updated version of code.
17336 (consing_since_gc): Now EMACS_INT, since a single hash table can
17337 use more than INT_MAX bytes.

17378 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
17379 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
17380 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
17381 * gmalloc.c (register_heapinfo): Use inline unconditionally.
17382 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
17384 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17386 Make it possible to run ./temacs.
17388 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
17389 syms_of_callproc does the same thing. Remove test for
17390 "initialized", do it in the caller.
17391 * emacs.c (main): Avoid calling set_initial_environment when dumping.
17393 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
17395 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
17396 (read_minibuf): Use get_minibuffer.
17397 (syms_of_minibuf): Use DEFSYM.
17398 (Qmetadata): New var.
17399 * data.c (Qbuffer): Don't make it static.
17400 (syms_of_data): Use DEFSYM.
17402 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
17404 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
17405 (CCL_CODE_MIN): New macro.
17407 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
17409 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
17411 * eval.c (Qdebug): Now static.
17412 * lisp.h (Qdebug): Remove decl. This reverts a part of the
17413 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
17414 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
17416 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
17418 * image.c: Various fixes to ImageMagick code comments.
17419 (Fimagemagick_types): Doc fix.
17421 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
17423 Minor fixes prompted by GCC 4.6.0 warnings.
17425 * xselect.c (converted_selections, conversion_fail_tag): Now static.
17427 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
17428 (x_clipboard_manager_save_all): Move extern decl to ...
17429 * xterm.h: ... here, so that it can be checked for consistency.
17431 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
17433 * xselect.c (x_clipboard_manager_save_frame)
17434 (x_clipboard_manager_save_all): New functions.
17435 (Fx_clipboard_manager_save): Lisp function deleted.
17437 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
17438 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
17440 * xterm.h: Update prototype.
17442 2011-05-28 William Xu <william.xwl@gmail.com>
17444 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
17445 exiting (Bug#8239).
17447 2011-05-28 Jim Meyering <meyering@redhat.com>
17449 Avoid a sign-extension bug in crypto_hash_function.
17450 * fns.c (to_uchar): Define.
17451 (crypto_hash_function): Use it to convert some newly-signed
17452 variables to unsigned, to avoid sign-extension bugs. For example,
17453 without this change, (md5 "truc") would evaluate to
17454 45723a2aff78ff4fff7fff1114760e62 rather than the expected
17455 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
17456 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
17458 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17460 Integer overflow fixes.
17462 * dbusbind.c: Serial number integer overflow fixes.
17463 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
17464 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
17465 to hold a serial number that is too large for a fixnum.
17466 (Fdbus_method_return_internal, Fdbus_method_error_internal):
17467 Check for serial numbers out of range. Decode any serial number
17468 that was so large that it became a float. (Bug#8722)
17470 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
17471 (Fdbus_call_method, Fdbus_call_method_asynchronously):
17472 Use XFASTINT rather than XUINT when numbers are nonnegative.
17473 (xd_append_arg, Fdbus_method_return_internal):
17474 (Fdbus_method_error_internal): Likewise. Also, for unsigned
17475 arguments, check that Lisp number is nonnegative, rather than
17476 silently wrapping negative numbers around. (Bug#8722)
17477 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
17480 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
17482 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
17484 ccl: Add integer overflow checks.
17485 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
17486 (IN_INT_RANGE): New macros.
17487 (ccl_driver): Use them to check for integer overflow when
17488 decoding a CCL program. Many of the new checks are whether XINT (x)
17489 fits in int; it doesn't always, on 64-bit hosts. The new version
17490 doesn't catch all possible integer overflows, but it's an
17491 improvement. (Bug#8719)
17493 * alloc.c (make_event_array): Use XINT, not XUINT.
17494 There's no need for unsigned here.
17496 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
17497 This follows up to the 2011-05-06 change that substituted uintptr_t
17498 for EMACS_INT. This case wasn't caught back then.
17500 Rework Fformat to avoid integer overflow issues.
17501 * editfns.c: Include <float.h> unconditionally, as it's everywhere
17502 now (part of C89). Include <verify.h>.
17503 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
17504 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
17505 (Fformat): Avoid the prepass trying to compute sizes; it was only
17506 approximate and thus did not catch overflow reliably. Instead, walk
17507 through the format just once, formatting and computing sizes as we go,
17508 checking for integer overflow at every step, and allocating a larger
17509 buffer as needed. Keep track separately whether the format is
17510 multibyte. Keep only the most-recently calculated precision, rather
17511 than them all. Record whether each argument has been converted to
17512 string. Use EMACS_INT, not int, for byte and char and arg counts.
17513 Support field widths and precisions larger than INT_MAX. Avoid
17514 sprintf's undefined behavior with conversion specifications such as %#d
17515 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
17516 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
17517 formatting out-of-range floating point numbers with int
17518 formats. (Bug#8668)
17520 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
17522 * data.c: Avoid integer truncation in expressions involving floats.
17523 * data.c: Include <intprops.h>.
17524 (arith_driver): When there's an integer overflow in an expression
17525 involving floating point, convert the integers to floating point
17526 so that the resulting value does not suffer from catastrophic
17527 integer truncation. For example, on a 64-bit host (* 4
17528 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
17529 Do not rely on undefined behavior after integer overflow.
17531 merge count_size_as_multibyte, parse_str_to_multibyte
17532 * character.c, character.h (count_size_as_multibyte):
17533 Rename from parse_str_to_multibyte; all uses changed.
17534 Check for integer overflow.
17535 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
17536 since it's now a duplicate of the other. This is more of
17537 a character than a buffer op, so better that it's in character.c.
17538 * fns.c, print.c: Adjust to above changes.
17540 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
17542 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
17544 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17546 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17547 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
17548 (x_clipboard_manager_save): Now static.
17549 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
17551 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17552 (crypto_hash_function): Now static.
17553 Fix pointer signedness problems. Avoid unnecessary initializations.
17555 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
17557 * termhooks.h (Vselection_alist): Make it terminal-local.
17559 * terminal.c (create_terminal): Initialize it.
17561 * xselect.c: Support for clipboard managers.
17562 (Vselection_alist): Move to termhooks.h as terminal-local var.
17563 (LOCAL_SELECTION): New macro.
17564 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
17565 (symbol_to_x_atom): Remove gratuitous arg.
17566 (x_handle_selection_request, lisp_data_to_selection_data)
17567 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
17568 (x_own_selection, x_get_local_selection, x_convert_selection):
17569 New arg, specifying work frame. Use terminal-local Vselection_alist.
17570 (some_frame_on_display): Delete unused function.
17571 (Fx_own_selection_internal, Fx_get_selection_internal)
17572 (Fx_disown_selection_internal, Fx_selection_owner_p)
17573 (Fx_selection_exists_p): New optional frame arg.
17574 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
17575 (x_handle_selection_clear): Don't treat other terminals with the
17576 same keyboard specially. Use the terminal-local Vselection_alist.
17577 (x_clear_frame_selections): Use Frun_hook_with_args.
17579 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
17581 * xterm.h: Add support for those atoms.
17583 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
17585 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
17586 (converted_selections, conversion_fail_tag): New global variables.
17587 (x_selection_request_lisp_error): Free the above.
17588 (x_get_local_selection): Remove unnecessary code.
17589 (x_reply_selection_request): Args changed; handle arbitrary array
17590 of converted selections stored in converted_selections.
17591 Separate the XChangeProperty and SelectionNotify steps.
17592 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
17593 (x_convert_selection): New function.
17594 (x_handle_selection_event): Simplify.
17595 (x_get_foreign_selection): Don't ignore incoming requests while
17596 waiting for an answer; this will fail when we implement
17597 SAVE_TARGETS, and seems unnecessary anyway.
17598 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
17599 (Vx_sent_selection_functions): Doc fix.
17601 2011-05-26 Leo Liu <sdl.web@gmail.com>
17603 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
17605 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17607 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
17609 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
17610 for fringe update if it has periodic bitmap.
17611 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
17612 and fringe_bitmap_periodic_p.
17614 * fringe.c (get_fringe_bitmap_data): New function.
17615 (draw_fringe_bitmap_1, update_window_fringes): Use it.
17616 (update_window_fringes): Record periodicity of fringe bitmap in glyph
17617 row. Mark glyph row for fringe update if periodicity changed.
17619 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
17620 for fringe update unless it has periodic bitmap.
17622 2011-05-25 Kenichi Handa <handa@m17n.org>
17624 * xdisp.c (get_next_display_element): Set correct it->face_id for
17625 a static composition.
17627 2011-05-24 Leo Liu <sdl.web@gmail.com>
17630 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
17632 * fns.c (crypto_hash_function, Fsha1): New function.
17633 (Fmd5): Use crypto_hash_function.
17634 (syms_of_fns): Add Ssha1.
17636 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
17638 * gnutls.c: Remove unused macros.
17639 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
17640 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
17641 Remove macros that are defined and never used.
17642 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
17644 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17646 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
17647 (Fx_get_selection_internal): Minor cleanup.
17648 (Fx_own_selection_internal): Rename arguments for consistency with
17651 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
17653 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
17655 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17657 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
17659 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17661 * dispnew.c (scrolling_window): Don't exclude the case that the
17662 last enabled row in the desired matrix touches the bottom boundary.
17664 2011-05-21 Glenn Morris <rgm@gnu.org>
17666 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
17667 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
17668 and add some more files.
17670 2011-05-20 Eli Zaretskii <eliz@gnu.org>
17672 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
17673 report_file_error introduced by the change from 2011-05-07.
17675 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
17677 * systime.h (Time): Define only if emacs is defined.
17678 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
17679 where the include path doesn't have X11/X.h by default. See
17680 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
17682 2011-05-20 Kenichi Handa <handa@m17n.org>
17684 * composite.c (find_automatic_composition): Fix previous change.
17686 2011-05-20 Glenn Morris <rgm@gnu.org>
17688 * lisp.mk: New file, split from Makefile.in.
17689 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
17690 (shortlisp): Remove.
17691 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
17693 2011-05-19 Glenn Morris <rgm@gnu.org>
17695 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
17696 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
17697 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
17698 (lisp): Set the order to that of loadup.el.
17699 (shortlisp): Make it a copy of $lisp.
17700 (SOME_MACHINE_LISP): Remove.
17701 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
17702 Use just $shortlisp, not $SOME_MACHINE_LISP too.
17704 2011-05-18 Kenichi Handa <handa@m17n.org>
17706 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
17707 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
17708 (find_automatic_composition): Mostly rewrite for efficiency.
17710 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
17712 * makefile.w32-in: Update dependencies.
17714 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
17716 * menu.c: Include limits.h (fixes the MS-Windows build broken by
17717 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
17719 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
17721 Fix some integer overflow issues, such as string length overflow.
17723 * insdel.c (count_size_as_multibyte): Check for string overflow.
17725 * character.c (lisp_string_width): Check for string overflow.
17726 Use EMACS_INT, not int, for string indexes and lengths; in
17727 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
17728 the resulting string length overflows an EMACS_INT; instead,
17729 report a string overflow if no precision given. When checking for
17730 precision exhaustion, use a check that cannot possibly have
17731 integer overflow. (Bug#8675)
17732 * character.h (lisp_string_width): Adjust to new signature.
17734 * alloc.c (string_overflow): New function.
17735 (Fmake_string): Use it. This doesn't change behavior, but saves
17736 a few bytes and will simplify future changes.
17737 * character.c (string_escape_byte8): Likewise.
17738 * lisp.h (string_overflow): New decl.
17740 Fixups, following up to the user-interface timestamp change.
17741 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
17742 for UI timestamps, instead of unsigned long.
17743 * msdos.c (mouse_get_pos): Likewise.
17744 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
17745 * w32gui.h (Time): Define by including "systime.h" rather than by
17746 declaring it ourselves. (Bug#8664)
17748 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
17749 * image.c (clear_image_cache): Likewise.
17751 * term.c (term_mouse_position): Don't assume time_t wraparound.
17753 Be more systematic about user-interface timestamps.
17754 Before, the code sometimes used 'Time', sometimes 'unsigned long',
17755 and sometimes 'EMACS_UINT', to represent these timestamps.
17756 This change causes it to use 'Time' uniformly, as that's what X uses.
17757 This makes the code easier to follow, and makes it easier to catch
17758 integer overflow bugs such as Bug#8664.
17759 * frame.c (Fmouse_position, Fmouse_pixel_position):
17760 Use Time, not unsigned long, for user-interface timestamps.
17761 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
17762 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
17763 * keyboard.h (last_event_timestamp): Likewise.
17764 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
17765 * menu.h (xmenu_show): Likewise.
17766 * term.c (term_mouse_position): Likewise.
17767 * termhooks.h (struct input_event.timestamp): Likewise.
17768 (struct terminal.mouse_position_hook): Likewise.
17769 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
17770 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
17771 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
17772 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
17773 what it was before.
17774 * menu.h, termhooks.h: Include "systime.h", for Time.
17776 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
17777 Don't assume that the difference between two unsigned long values
17778 can fit into an integer. At this point, we know button_down_time
17779 <= event->timestamp, so the difference must be nonnegative, so
17780 there's no need to cast the result if double-click-time is
17781 nonnegative, as it should be; check that it's nonnegative, just in
17782 case. This bug is triggered when events are more than 2**31 ms
17783 apart (about 25 days). (Bug#8664)
17785 * xselect.c (last_event_timestamp): Remove duplicate decl.
17786 (x_own_selection): Remove needless cast to unsigned long.
17788 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
17789 that always fit in int. Use a sentinel instead of a counter, to
17790 avoid a temp and to allay GCC's concerns about possible int overflow.
17791 * frame.h (struct frame): Use int for menu_bar_items_used
17792 instead of EMACS_INT, since it always fits in int.
17794 * menu.c (grow_menu_items): Check for int overflow.
17796 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
17798 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
17799 Before, the code was not consistent. These values cannot exceed
17800 2**31 - 1 so there's no need to make them unsigned.
17801 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
17802 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
17803 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
17805 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
17807 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
17808 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
17809 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
17810 presumably because the widths might not match.
17812 * window.c (size_window): Avoid needless test at loop start.
17814 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
17816 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
17818 2011-05-12 Drew Adams <drew.adams@oracle.com>
17820 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
17822 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17824 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
17825 `width' to `bar_area_x' and `bar_area_width', respectively.
17826 (x_scroll_run): Take account of fringe background extension.
17828 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
17829 Rename local vars `left' and `width' to `bar_area_x' and
17830 `bar_area_width', respectively.
17831 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
17832 background extension.
17834 2011-05-10 Jim Meyering <meyering@redhat.com>
17836 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
17838 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
17840 * image.c (Finit_image_library): Return t for built-in image types,
17841 like pbm and xbm. (Bug#8640)
17843 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
17845 * w32menu.c (set_frame_menubar): Fix submenu allocation.
17847 2011-05-07 Eli Zaretskii <eliz@gnu.org>
17849 * w32console.c (Fset_screen_color): Doc fix.
17850 (Fget_screen_color): New function.
17851 (syms_of_ntterm): Defsubr it.
17853 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
17854 unlink the temporary file if Fcall_process didn't create it in the
17856 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
17857 child process will be redirected to a file specified with `:file'.
17858 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
17859 cue to call_process_cleanup not to close that handle.
17861 2011-05-07 Ben Key <bkey76@gmail.com>
17863 * makefile.w32-in: The bootstrap-temacs rule now makes use of
17864 one of two shell specific rules, either bootstrap-temacs-CMD or
17865 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
17866 to the previous implementation of the bootstrap-temacs rule.
17867 The bootstrap-temacs-CMD rule is similar to the previous
17868 implementation of the bootstrap-temacs rule except that it
17869 makes use of the ESC_CFLAGS variable instead of the CFLAGS
17872 These changes, along with some changes to nt/configure.bat,
17873 nt/gmake.defs, and nt/nmake.defs, are required to extend my
17874 earlier fix to add support for --cflags and --ldflags options
17875 that include quotes so that it works whether make uses cmd or
17878 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
17880 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
17881 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
17883 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
17884 a string. Handle both cases.
17885 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
17886 (Fdbus_register_method): Use Qinvalid_function.
17888 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
17890 * makefile.w32-in: Update dependencies.
17891 (LISP_H): Add inttypes.h and stdin.h.
17892 (PROCESS_H): Add unistd.h.
17894 2011-05-06 Eli Zaretskii <eliz@gnu.org>
17896 * lread.c: Include limits.h (fixes the MS-Windows build broken by
17897 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
17899 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
17901 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
17903 * term.c (vfatal): Remove stray call to va_end.
17904 It's not needed and the C Standard doesn't allow it here anyway.
17906 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
17907 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
17909 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
17912 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
17914 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
17916 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
17918 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
17920 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
17922 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
17923 * charset.c (Fdefine_charset_internal): Don't initialize
17924 charset.code_space[15]. The value was garbage, on hosts with
17925 32-bit int (Bug#8600).
17927 * lread.c (read_integer): Be more consistent with string-to-number.
17928 Use string_to_number to do the actual conversion; this avoids
17929 rounding errors and fixes some other screwups. Without this fix,
17930 for example, #x1fffffffffffffff was misread as -2305843009213693952.
17931 (digit_to_number): Move earlier, for benefit of read_integer.
17932 Return -1 if the digit is out of range for the base, -2 if it is
17933 not a digit in any supported base. (Bug#8602)
17935 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
17937 * dispnew.c (scrolling_window): Return 1 if we scrolled,
17938 to match comment at start of function. This also removes a
17939 GCC warning about overflow in a 32+64-bit port.
17941 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
17943 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
17944 Reported by Stefan Monnier in
17945 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
17946 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
17947 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
17949 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
17950 (EMACS_UINTPTR): Likewise, with uintptr_t.
17952 * lisp.h: Prefer 64-bit EMACS_INT if available.
17953 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
17954 on 32-bit hosts that have 64-bit int, so that they can access
17956 However, temporarily disable this change unless the temporary
17957 symbol WIDE_EMACS_INT is defined.
17959 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
17961 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
17962 This removes an assumption that EMACS_INT and long are the same
17963 width as pointers. The assumption is true for Emacs porting targets
17964 now, but we want to make other targets possible.
17965 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
17966 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
17967 In the rest of the code, change types of integers that hold casted
17968 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
17969 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
17970 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
17971 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
17972 No need to cast type when ORing.
17973 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
17974 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
17975 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
17976 assume EMACS_INT is the same width as char *.
17977 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
17978 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
17979 Remove no-longer-needed casts.
17980 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
17981 (xg_tool_bar_help_callback, xg_make_tool_item):
17982 Use EMACS_INTPTR to hold an integer
17983 that will be cast to void *; this can avoid a GCC warning
17984 if EMACS_INT is not the same width as void *.
17985 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
17986 * xdisp.c (display_echo_area_1, resize_mini_window_1):
17987 (current_message_1, set_message_1):
17988 Use a local to convert to proper width without a cast.
17989 * xmenu.c (dialog_selection_callback): Likewise.
17991 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
17992 Also, don't assume VALBITS / RAND_BITS is less than 5,
17993 and don't rely on undefined behavior when shifting a 1 left into
17995 * lisp.h (get_random): Change signature to match.
17997 * lread.c (hash_string): Use size_t, not int, for hash computation.
17998 Normally we prefer signed values; but hashing is special, because
17999 it's better to use unsigned division on hash table sizes so that
18000 the remainder is nonnegative. Also, size_t is the natural width
18001 for hashing into memory. The previous code used 'int', which doesn't
18002 retain enough info to hash well into very large tables.
18003 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
18005 * dbusbind.c: Don't possibly lose pointer info when converting.
18006 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18007 Use XPNTR rather than XHASH, so that the high-order bits of
18008 the pointer aren't lost when converting through void *.
18010 * eval.c (Fautoload): Don't double-shift a pointer.
18012 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
18014 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18016 * gnutls.c (DEF_GNUTLS_FN):
18017 * image.c (DEF_IMGLIB_FN): Make function pointers static.
18019 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
18021 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
18024 2011-05-05 Eli Zaretskii <eliz@gnu.org>
18026 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
18027 New version that can reserve upto 2GB of heap space.
18029 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
18031 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).

18035 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
18036 `gnutls_certificate_set_x509_key_file'.
18038 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
18040 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
18041 Update dependencies.
18043 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18045 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
18046 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
18047 Remove unused parameter `fildes'.
18048 * process.c (read_process_output, send_process): Don't pass it.
18050 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18052 Fix previous change: the library cache is defined in w32.c.
18053 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
18054 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
18056 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18058 Implement dynamic loading of GnuTLS on Windows.
18060 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
18061 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
18062 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18065 * gnutls.c (Qgnutls_dll): Define.
18066 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
18067 (gnutls_*): Declare function pointers.
18068 (init_gnutls_functions): New function to initialize function pointers.

18071 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18072 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
18073 (emacs_gnutls_write, emacs_gnutls_read)
18074 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
18075 (Fgnutls_available_p): New function.
18076 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

18084 (w32_delayed_load): Move to w32.c.
18086 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
18088 * w32.c (QCloaded_from, Vlibrary_cache): Define.
18089 (w32_delayed_load): Move from image.c. When loading a library, record
18090 its filename in the :loaded-from property of the library id.
18091 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
18092 Initialize and staticpro them.
18093 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
18095 * process.c: Include lisp.h before w32.h, not after.
18096 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
18097 instead of gnutls_record_check_pending.
18099 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
18101 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
18103 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
18104 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
18107 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
18109 * xterm.c (x_set_frame_alpha): Do not set property on anything

18132 * sysdep.c (wait_for_termination_1): Make static.
18133 (wait_for_termination, interruptible_wait_for_termination):
18134 Move after wait_for_termination_1.
18136 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
18138 * sysdep.c (interruptible_wait_for_termination): New function
18139 which is like wait_for_termination, but allows keyboard
18142 * callproc.c (Fcall_process): Add (:file "file") as an option for
18144 (Fcall_process_region): Ditto.
18146 2011-04-30 Eli Zaretskii <eliz@gnu.org>
18148 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
18149 rather than `XVECTOR (FOO)->size'.
18151 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
18152 inttypes.h, as a gnulib replacement is used if it not available in
18155 2011-04-21 Eli Zaretskii <eliz@gnu.org>
18157 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
18158 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
18159 of MOST_POSITIVE_FIXNUM. (Bug#8528)
18161 * coding.c (coding_alloc_by_realloc): Error out if destination
18162 will grow beyond MOST_POSITIVE_FIXNUM.
18163 (decode_coding_emacs_mule): Abort if there isn't enough place in

18176 * window.c (window_scroll_line_based): Use a marker instead of
18177 simple variables to record original value of point. (Bug#7952)
18179 * doprnt.c (doprnt): Fix the case where a multibyte sequence
18180 produced by %s or %c overflows available buffer space. (Bug#8545)
18182 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
18184 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
18185 (SIZE_MAX): Move defn after all includes, as they might #define it.
18187 2011-04-28 Juanma Barranquero <lekktu@gmail.com>

18219 Improve `doprnt' and its usage. (Bug#8545)
18220 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
18221 `format_end'. Remove support for %l as a conversion specifier.
18222 Don't use xrealloc. Improve diagnostics when the %l size modifier
18223 is used. Update the commentary.
18225 * eval.c (verror): Simplify calculation of size_t.
18227 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
18230 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
18232 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
18235 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18237 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
18238 This makes this file independent of the recent pseudovector change.
18240 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
18242 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
18244 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
18245 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
18246 Remove unused local.
18247 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
18249 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
18250 GCC 4.6.0 optimizes based on type-based alias analysis.
18251 For example, if b is of type struct buffer * and v of type struct
18252 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
18253 != &v->size, and therefore "v->size = 1; b->size = 2; return
18254 v->size;" must therefore return 1. This assumption is incorrect
18255 for Emacs, since it type-puns struct Lisp_Vector * with many other
18256 types. To fix this problem, this patch adds a new type struct
18257 vectorlike_header that documents the constraints on layout of vectors
18258 and pseudovectors, and helps optimizing compilers not get fooled
18259 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
18260 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
18261 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
18263 (XSETPVECTYPE): Rewrite in terms of new macro.
18264 (XSETPVECTYPESIZE): New macro, specifying both type and size.
18265 This is a bit clearer, and further avoids the possibility of
18266 undesirable aliasing.
18267 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
18268 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
18269 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
18270 since Lisp_Subr is a special case (no "next" field).
18271 (ASIZE): Now uses header.size rather than size.
18272 All previous uses of XVECTOR (foo)->size replaced to use this macro,
18273 to avoid the hassle of writing XVECTOR (foo)->header.size.
18274 (struct vectorlike_header): New type.
18275 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
18276 object, to help avoid aliasing.
18277 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
18278 (SUBRP): Likewise, since Lisp_Subr is a special case.
18279 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
18280 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
18281 (struct Lisp_Hash_Table): Combine first two members into a single
18282 struct vectorlike_header member. All uses of "size" and "next" members
18283 changed to be "header.size" and "header.next".
18284 * buffer.h (struct buffer): Likewise.
18285 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
18286 * frame.h (struct frame): Likewise.
18287 * process.h (struct Lisp_Process): Likewise.
18288 * termhooks.h (struct terminal): Likewise.
18289 * window.c (struct save_window_data, struct saved_window): Likewise.
18290 * window.h (struct window): Likewise.
18291 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
18292 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
18293 * buffer.c (init_buffer_once): Likewise.
18294 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
18296 * process.c (Fformat_network_address): Use local var for size,
18299 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
18301 Make the Lisp reader and string-to-float more consistent (Bug#8525)
18302 * data.c (atof): Remove decl; no longer used or needed.
18303 (digit_to_number): Move to lread.c.
18304 (Fstring_to_number): Use new string_to_number function, to be
18305 consistent with how the Lisp reader treats infinities and NaNs.
18306 Do not assume that floating-point numbers represent EMACS_INT
18307 without losing information; this is not true on most 64-bit hosts.
18308 Avoid double-rounding errors, by insisting on integers when
18309 parsing non-base-10 numbers, as the documentation specifies.
18310 * lisp.h (string_to_number): New decl, replacing ...
18311 (isfloat_string): Remove.
18312 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
18313 (read1): Do not accept +. and -. as integers; this
18314 appears to have been a coding error. Similarly, do not accept
18315 strings like +-1e0 as floating point numbers. Do not report
18316 overflow for integer overflows unless the base is not 10 which
18317 means we have no simple and reliable way to continue.
18318 Break out the floating-point parsing into a new
18319 function string_to_number, so that Fstring_to_number parses
18320 floating point numbers consistently with the Lisp reader.
18321 (digit_to_number): Move here from data.c. Make it static inline.
18322 (E_CHAR, EXP_INT): Remove, replacing with ...
18323 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
18324 (string_to_number): New function, replacing isfloat_string.
18325 This function checks for valid syntax and produces the resulting
18326 Lisp float number too. Rework it so that string-to-number
18327 no longer mishandles examples like "1.0e+". Use strtoumax,
18328 so that overflow for non-base-10 numbers is reported only when
18329 there's no portable and simple way to convert to floating point.
18331 * textprop.c (set_text_properties_1): Rewrite for clarity,
18332 and to avoid GCC warning about integer overflow.
18334 * intervals.h (struct interval): Use EMACS_INT for members
18335 where EMACS_UINT might cause problems. See
18336 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
18337 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
18338 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
18340 (offset_intervals): Tell GCC not to worry about length overflow
18341 when negating a negative length.
18343 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
18344 (overrun_check_free): Likewise.
18346 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
18347 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
18350 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18351 (gnutls_make_error): Rename local to avoid shadowing.
18352 (gnutls_emacs_global_deinit): ifdef out; not used.
18353 (Fgnutls_boot): Use const for pointer to readonly storage.
18354 Comment out unused local. Fix pointer signedness problems.
18356 * lread.c (openp): Don't stuff size_t into an 'int'.
18357 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
18358 about possible signed overflow.
18360 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18361 (GDK_KEY_g): Don't define if already defined.
18362 (xg_prepare_tooltip): Avoid pointer signedness problem.
18363 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
18365 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
18366 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
18368 * xfns.c (Fx_window_property): Simplify a bit,
18369 to make a bit faster and to avoid GCC 4.6.0 warning.
18370 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
18372 * fns.c (internal_equal): Don't assume size_t fits in int.
18374 * alloc.c (compact_small_strings): Tighten assertion a little.
18376 Replace pEd with more-general pI, and fix some printf arg casts.
18377 * lisp.h (pI): New macro, generalizing old pEd macro to other
18378 conversion specifiers. For example, use "...%"pI"d..." rather
18379 than "...%"pEd"...".
18380 (pEd): Remove. All uses replaced with similar uses of pI.
18381 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
18382 * alloc.c (check_pure_size): Don't overflow by converting size to int.
18383 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
18384 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
18385 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
18386 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
18387 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
18389 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
18390 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
18391 * print.c (safe_debug_print, print_object): Likewise.
18392 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
18394 Use pI instead of if-then-else-abort. Use %p to avoid casts,
18395 avoiding the 0 flag, which is not portable.
18396 * process.c (Fmake_network_process): Use pI to avoid cast.
18397 * region-cache.c (pp_cache): Likewise.
18398 * xdisp.c (decode_mode_spec): Likewise.
18399 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
18400 behavior on 64-bit hosts with printf arg.
18401 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
18402 (x_stop_queuing_selection_requests): Likewise.
18403 (x_get_window_property): Don't truncate byte count to an 'int'
18406 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
18407 here, since it parses constructs like leading '-' and spaces,
18408 which are not wanted; and it overflows with large numbers.
18409 Instead, simply match F[0-9]+, which is what is wanted anyway.
18411 * alloc.c: Remove unportable assumptions about struct layout.
18412 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
18413 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
18414 (allocate_vectorlike, make_pure_vector): Use the new macros,
18415 plus offsetof, to remove unportable assumptions about struct layout.
18416 These assumptions hold on all porting targets that I know of, but
18417 they are not guaranteed, they're easy to remove, and removing them
18418 makes further changes easier.
18420 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
18421 This doesn't fix a bug but makes the code clearer.
18422 (string_overrun_cookie): Now const. Use initializers that
18423 don't formally overflow signed char, to avoid warnings.
18424 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
18425 can cause Emacs to crash when string overrun checking is enabled.
18426 (allocate_buffer): Don't assume sizeof (struct buffer) is a
18427 multiple of sizeof (EMACS_INT); it need not be, if
18428 alignof(EMACS_INT) < sizeof (EMACS_INT).
18429 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
18431 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

18438 supposed to be handshaking. (Bug#8556)
18439 Reported by Paul Eggert <eggert@cs.ucla.edu>.
18441 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

18446 (handle_user_signal): Break into debugger when debug-on-event
18447 matches the current signal symbol.

18451 * alloc.c (check_sblock, check_string_bytes)
18452 (check_string_free_list): Convert to standard C.
18454 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
18456 * w32.c (emacs_gnutls_push): Fix typo.
18458 2011-04-25 Eli Zaretskii <eliz@gnu.org>
18460 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
18461 "cast to pointer from integer of different size".
18463 Improve doprnt and its use in verror. (Bug#8545)
18464 * doprnt.c (doprnt): Document the set of format control sequences
18465 supported by the function. Use SAFE_ALLOCA instead of always
18468 * eval.c (verror): Don't limit the buffer size at size_max-1, that
18469 is one byte too soon. Don't use xrealloc; instead xfree and
18472 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
18474 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
18477 * gnutls.c: Renamed global_initialized to
18478 gnutls_global_initialized. Added internals for the
18479 :verify-hostname-error, :verify-error, and :verify-flags
18480 parameters of `gnutls-boot' and documented those parameters in the
18481 docstring. Start callback support.
18482 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
18483 unless a fatal error occurred. Call gnutls_alert_send_appropriate
18484 on error. Return error code.

18486 (emacs_gnutls_read): Likewise.
18487 (Fgnutls_boot): Return handshake error code.
18488 (emacs_gnutls_handle_error): New function.

18556 * doprnt.c: Include limits.h.
18557 (SIZE_MAX): New macro.
18558 (doprnt): Return a size_t value. 2nd arg is now size_t.
18559 Many local variables are now size_t instead of int or unsigned.
18560 Improve overflow protection. Support `l' modifier for integer
18561 conversions. Support %l conversion. Don't assume an EMACS_INT
18562 argument for integer conversions and for %c.
18564 * lisp.h (doprnt): Restore prototype.
18566 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
18567 $(SRC)/character.h.
18569 * Makefile.in (base_obj): Add back doprnt.o.
18571 * deps.mk (doprnt.o): Add back prerequisites.
18572 (callint.o): Depend on character.h.
18574 * eval.c (internal_lisp_condition_case): Include the handler
18575 representation in the error message.
18576 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
18577 when breaking from the loop.
18579 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
18581 * callint.c (Fcall_interactively): When displaying error message
18582 about invalid control letter, pass the character's codepoint, not
18583 a pointer to its multibyte form. Improve display of the character
18584 in octal and display also its hex code.
18586 * character.c (char_string): Use %x to display the (unsigned)
18587 codepoint of an invalid character, to avoid displaying a bogus
18590 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
18591 `error', not SYMBOL_NAME itself.
18593 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
18594 character arguments to `error'.
18596 * charset.c (check_iso_charset_parameter): Fix incorrect argument
18597 to `error' in error message about FINAL_CHAR argument. Make sure
18598 FINAL_CHAR is a character, and use %c when it is passed as
18599 argument to `error'.

18663 Define only if needed.
18665 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
18666 by pacifying GCC about it. Maybe it's time to retire it?
18667 * xfaces.c (USG, __TIMEVAL__): Likewise.
18669 * dispextern.h (struct redisplay_interface): Rename param
18670 to avoid shadowing.
18671 * termhooks.h (struct terminal): Likewise.
18672 * xterm.c (xembed_send_message): Likewise.
18674 * insdel.c (make_gap_smaller): Define only if
18675 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
18677 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
18680 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
18681 so that we aren't warned about unused symbols.
18683 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
18685 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).
18687 * xfns.c (x_real_positions): Mark locals as initialized.
18689 * xmenu.c (xmenu_show): Don't use uninitialized vars.
18691 * xterm.c: Fix problems found by static analysis with other toolkits.
18692 (toolkit_scroll_bar_interaction): Define and use only if USE_X_TOOLKIT.

19130 * charset.h (charset_iso_8859_1): Remove decl.
19131 * charset.c (charset_iso_8859_1, charset_emacs, map_charset_for_dump):
19134 * ccl.h (check_ccl_update, Vccl_program_table): Remove decls.
19135 * ccl.c (Vccl_program_table): Now static.
19136 (check_ccl_update): Remove; unused.
19138 * category.c (SET_CATEGORY_SET, set_category_set): Move here.
19139 * category.h: ... from here.
19140 * category.c (check_category_table, set_category_set): Now static.
19142 * casetab.c (Vascii_upcase_table, Vascii_eqv_table): Now static.
19143 * lisp.h: Remove these decls.
19145 * buffer.c (buffer_count): Remove unused var.
19147 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
19148 so that it's not optimized away.
19149 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
19150 * dispextern.h (bidi_dump_cached_states): Remove, since it's
19151 exported only to the debugger.
19153 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
19154 * atimer.h (run_all_atimers): Remove; not exported.
19156 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
19157 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
19158 was inaccessible from Lisp.
19159 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
19160 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
19162 alloc.c: Import and export fewer symbols, and remove unused items.
19163 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
19165 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
19166 it's not optimized away by whole-program optimization.
19167 (message_enable_multibyte, free_misc): Remove.
19168 (catchlist, handlerlist, mark_backtrace):
19169 Declare only if BYTE_MARK_STACK.
19170 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
19171 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
19172 (message_enable_multibyte): Remove decl.
19173 (free_misc, interval_free_list, float_block, float_block_index):
19174 (n_float_blocks, float_free_list, cons_block, cons_block_index):
19175 (cons_free_list, last_marked_index):
19177 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
19178 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
19179 (mark_backtrace): Define only if BYTE_MARK_STACK.
19180 * xdisp.c (message_enable_multibyte): Now static.
19182 Declare Lisp_Object Q* variables to be 'static' if not exported.
19183 This makes it easier for human readers (and static analyzers)
19184 to see whether these variables are used from other modules.
19185 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
19186 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
19187 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:
19188 * font.c, frame.c, fringe.c, ftfont.c, image.c, keyboard.c, keymap.c:

19190 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
19191 * xmenu.c, xselect.c:
19192 Declare Q* vars static if they are not used in other modules.
19193 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
19194 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
19195 Remove decls of unexported vars.
19196 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
19198 * lisp.h (DEFINE_FUNC): Make sname 'static'.
19200 Make Emacs functions such as Fatom 'static' by default.
19201 This makes it easier for human readers (and static analyzers)
19202 to see whether these functions can be called from other modules.
19203 DEFUN now defines a static function. To make the function external
19204 so that it can be used in other C modules, use the new macro DEFUE.
19205 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
19206 (Finit_image_library):
19207 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
19208 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
19209 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
19210 Remove decls, since these functions are now static.
19211 (Funintern, Fget_internal_run_time): New decls, since these functions
19212 were already external.
19214 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
19215 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

19219 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
19220 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
19221 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
19222 Mark functions with DEFUE instead of DEFUN,
19223 if they are used in other modules.
19224 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
19225 decls for now-static functions.
19226 * buffer.h (Fdelete_overlay): Remove decl.
19227 * callproc.c (Fgetenv_internal): Mark as internal.
19228 * composite.c (Fremove_list_of_text_properties): Remove decl.

19232 * doc.c (Fdocumntation_property): New forward static decl.
19233 * eval.c (Ffetch_bytecode): New forward static decl.
19234 (Funintern): Remove extern decl; now in .h file where it belongs.
19235 * fileio.c (Fmake_symbolic_link): New forward static decl.
19236 * image.c (Finit_image_library): New forward static decl.
19237 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
19238 * intervals.h (Fprevious_property_change):
19239 (Fremove_list_of_text_properties): Remove decls.
19240 * keyboard.c (Fthis_command_keys): Remove decl.
19241 (Fcommand_execute): New forward static decl.
19242 * keymap.c (Flookup_key): New forward static decl.
19243 (Fcopy_keymap): Now static.
19244 * keymap.h (Flookup_key): Remove decl.
19245 * process.c (Fget_process): New forward static decl.
19246 (Fprocess_datagram_address): Mark as internal.

19257 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
19259 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
19262 2011-04-13 Eli Zaretskii <eliz@gnu.org>
19264 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
19265 when at ZV. (Bug#8487)
19267 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
19269 * charset.c (Fclear_charset_maps): Use xfree instead of free.
19271 * keyboard.c (parse_tool_bar_item): Likewise.
19272 * sound.c (sound_cleanup, alsa_close): Likewise.
19273 * termcap.c (tgetent): Likewise.
19274 * xfns.c (x_default_font_parameter): Likewise.
19275 * xsettings.c (read_and_apply_settings): Likewise.
19277 * alloc.c (overrun_check_malloc, overrun_check_realloc)
19278 (overrun_check_free): Protoize.
19280 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
19282 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
19283 since callers should never pass a negative size.
19284 Change the signature to match that of plain 'read' and 'write'; see
19285 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
19286 * lisp.h: Update prototypes of emacs_write and emacs_read.
19288 2011-04-11 Eli Zaretskii <eliz@gnu.org>
19290 * xdisp.c (redisplay_window): Don't try to determine the character
19291 position of the scroll margin if the window start point w->startp
19292 is outside the buffer's accessible region. (Bug#8468)
19294 2011-04-10 Eli Zaretskii <eliz@gnu.org>
19296 Fix write-region and its subroutines for buffers > 2GB.
19297 * fileio.c (a_write, e_write): Modify declaration of arguments and
19298 local variables to support buffers larger than 2GB.
19299 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
19301 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
19302 argument, local variables, and return value.
19304 * lisp.h: Update prototypes of emacs_write and emacs_read.
19306 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
19308 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
19310 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
19312 Fix more problems found by GCC 4.6.0's static checks.
19314 * xdisp.c (vmessage): Use a better test for character truncation.
19316 * charset.c (load_charset_map): <, not <=, for optimization,
19317 and to avoid potential problems with integer overflow.
19318 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
19319 * casetab.c (set_identity, shuffle): Likewise.
19320 * editfns.c (Fformat): Likewise.
19321 * syntax.c (skip_chars): Likewise.
19323 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
19324 This also lets GCC 4.6.0 generate slightly better loop code.
19326 * callint.c (Fcall_interactively): <, not <=, for optimization.
19327 (Fcall_interactively): Count the number of arguments produced,
19328 not the number of arguments given. This is simpler and lets GCC
19329 4.6.0 generate slightly better code.
19331 * ftfont.c: Distingish more carefully between FcChar8 and char.
19332 The previous code passed unsigned char * to a functions like
19333 strlen and xstrcasecmp that expect char *, which does not
19334 conform to the C standard.
19335 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
19336 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
19337 char * when the C standard requires it.
19339 * keyboard.c (read_char): Remove unused var.
19341 * eval.c: Port to Windows vsnprintf (Bug#8435).
19342 Include <limits.h>.
19343 (SIZE_MAX): Define if the headers do not.
19344 (verror): Do not give up if vsnprintf returns a negative count.
19345 Instead, grow the buffer. This ports to Windows vsnprintf, which
19346 does not conform to C99. Problem reported by Eli Zaretskii.
19347 Also, simplify the allocation scheme, by avoiding the need for
19348 calling realloc, and removing the ALLOCATED variable.
19350 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
19352 Remove invocations of doprnt, as Emacs now uses vsnprintf.
19353 But keep the doprint source code for now, as we might revamp it
19354 and use it again (Bug#8435).
19355 * lisp.h (doprnt): Remove.
19356 * Makefile.in (base_obj): Remove doprnt.o.
19357 * deps.mk (doprnt.o): Remove.
19359 error: Print 32- and 64-bit integers portably (Bug#8435).
19360 Without this change, on typical 64-bit hosts error ("...%d...", N)
19361 was used to print both 32- and 64-bit integers N, which relied on
19362 undefined behavior.
19363 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
19364 * lisp.h (error, verror): Mark as printf-like functions.
19365 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
19366 Report overflow in size calculations when allocating printf buffer.
19367 Do not truncate output string at its first null byte.
19368 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
19369 Truncate the output at a character boundary, since vsnprintf does not
19371 * charset.c (check_iso_charset_parameter): Convert internal
19372 character to string before calling 'error', since %c now has the
19374 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
19375 overflow when computing char to be passed to 'error'. Do not
19376 pass Lisp_Object to 'error'; pass the integer instead.
19377 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
19378 formatted with plain %d.
19380 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
19382 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
19384 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
19386 * xterm.c (x_catch_errors): Remove duplicate declaration.
19388 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
19390 * xdisp.c, lisp.h (message_nolog): Remove; unused.
19392 2011-04-10 Jim Meyering <meyering@redhat.com>
19394 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
19395 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
19396 return ssize_t not "int", and use size_t as the buffer length.
19397 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
19398 * gnutls.h: Update declarations.
19399 * process.c (read_process_output): Use ssize_t, to match.
19400 (send_process): Likewise.
19402 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19404 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
19406 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19408 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
19409 Use unsigned char, to match FcChar8 type definition.
19411 * xterm.c (handle_one_xevent):
19412 * xmenu.c (create_and_show_popup_menu):
19413 * xselect.c (x_decline_selection_request)
19414 (x_reply_selection_request): Avoid type-punned deref of X events.
19416 2011-04-09 Eli Zaretskii <eliz@gnu.org>
19418 Fix some uses of `int' instead of EMACS_INT.
19419 * search.c (string_match_1, fast_string_match)
19420 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
19421 (scan_buffer, find_next_newline_no_quit)
19422 (find_before_next_newline, search_command, Freplace_match)
19423 (Fmatch_data): Make some `int' variables be EMACS_INT.
19425 * xdisp.c (display_count_lines): 3rd argument and return value now
19426 EMACS_INT. All callers changed.
19427 (pint2hrstr): Last argument is now EMACS_INT.
19429 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
19430 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
19431 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
19432 (decode_coding_utf_16, decode_coding_emacs_mule)
19433 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
19434 (decode_coding_ccl, decode_coding_charset)
19435 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
19436 (decode_coding_iso_2022, decode_coding_emacs_mule)
19437 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
19438 <char_offset, last_offset>: Declare EMACS_INT.

19440 (encode_coding_emacs_mule, encode_invocation_designation)
19441 (encode_designation_at_bol, encode_coding_iso_2022)
19442 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
19443 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
19445 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
19446 (encode_invocation_designation): Last argument P_NCHARS is now
19448 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
19449 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
19451 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
19454 * ccl.c (Fccl_execute_on_string): Declare some variables
19457 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
19459 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
19461 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
19463 * process.c (Fformat_network_address): Doc fix.
19465 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
19467 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
19469 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
19471 * keyboard.c (read_char): Call Lisp function help-form-show,
19472 instead of using internal_with_output_to_temp_buffer.
19473 (Qhelp_form_show): New var.
19474 (syms_of_keyboard): Use DEFSYM macro.
19476 * print.c (internal_with_output_to_temp_buffer): Function deleted.

19480 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
19482 * process.c (Flist_processes): Remove to Lisp.
19483 (list_processes_1): Delete.
19485 2011-04-06 Eli Zaretskii <eliz@gnu.org>
19487 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
19489 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
19491 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
19493 Fix more problems found by GCC 4.6.0's static checks.
19495 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
19497 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
19499 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
19501 * xdisp.c (vmessage): Mark as a printf-like function.
19503 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
19505 * sound.c (sound_warning): Don't crash if arg contains a printf format.
19507 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
19508 printf-like functions.
19509 (tiff_load): Add casts to remove these marks before passing them
19510 to system-supplied API.
19512 * eval.c (Fsignal): Remove excess argument to 'fatal'.
19514 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
19515 This avoids several warnings with gcc -Wstrict-overflow.
19516 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
19517 directly, rather than having caller test rule sign. This avoids
19518 some unnecessary tests.
19519 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
19520 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
19521 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
19523 * xfont.c (xfont_text_extents): Remove var that was set but not used.
19524 (xfont_open): Avoid unnecessary tests.
19526 * composite.c (composition_gstring_put_cache): Use unsigned integer.

19535 by using the new macro.
19537 * textprop.c (set_text_properties_1): Change while to do-while,
19538 since the condition is always true at first.
19540 * intervals.c (graft_intervals_into_buffer): Mark var as used.
19541 (interval_deletion_adjustment): Return unsigned value.
19544 * process.c (list_processes_1, create_pty, read_process_output):
19545 (exec_sentinel): Remove vars that were set but not used.
19546 (create_pty): Remove unnecessary "volatile"s.

19557 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
19558 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
19560 * print.c (print_error_message): Avoid int overflow.
19562 * font.c (font_list_entities): Redo for clarity,
19563 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.

19573 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
19574 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
19575 can always succeed if overflow has undefined behavior.

19578 (wordify): Omit three unnecessary tests.
19580 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
19581 All callers changed. This avoids the need for an unused var.
19583 * casefiddle.c (casify_region): Remove var that is set but not used.
19585 * dired.c (file_name_completion): Remove var that is set but not used.
19587 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
19589 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
19590 (Finsert_file_contents): Remove unnecessary code checking fd.
19592 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
19593 Check for integer overflow on size calculations.
19595 * buffer.c (Fprevious_overlay_change): Remove var that is set
19598 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
19599 Remove vars that are set but not used.
19600 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
19601 (timer_check_2): Mark vars as initialized.
19603 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
19605 * image.c (lookup_image): Remove var that is set but not used.
19606 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
19608 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
19609 that are set but not used.
19611 * xfns.c (make_invisible_cursor): Don't return garbage
19612 if XCreateBitmapFromData fails (Bug#8410).
19614 * xselect.c (x_get_local_selection, x_handle_property_notify):
19615 Remove vars that are set but not used.
19617 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
19618 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
19620 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
19621 Remove var that is set but not used.
19622 (scroll_bar_windows_size): Now size_t, not int.
19623 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
19624 Check for overflow.
19626 * xfaces.c (realize_named_face): Remove vars that are set but not used.
19627 (map_tty_color) [!defined MSDOS]: Likewise.
19629 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
19631 * coding.c: Remove vars that are set but not used.
19632 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
19633 All callers changed.
19634 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
19635 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
19636 (decode_coding_charset): Remove vars that are set but not used.
19638 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
19639 that is set but not used.
19641 * print.c (print_object): Remove var that is set but not used.
19643 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
19644 The gnulib version avoids calling malloc in the usual case,
19645 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
19646 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
19647 * filelock.c (current_lock_owner): Likewise.
19648 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
19649 * sysdep.c: Include allocator.h, careadlinkat.h.
19650 (emacs_no_realloc_allocator): New static constant.
19651 (emacs_readlink): New function.
19652 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
19653 ../lib/careadlinkat.h.
19655 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
19657 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
19658 first non-nil return value).

19667 * xdisp.c (display_count_lines): Remove parameter `start',
19668 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
19669 (get_char_face_and_encoding): Remove parameter `multibyte_p',
19670 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

19672 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
19673 and thereabouts. All callers changed.
19674 (get_per_char_metric): Remove parameter `f', unused since
19675 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
19677 2011-04-02 Jim Meyering <meyering@redhat.com>
19679 do not dereference NULL upon failed strdup
19680 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
19681 (ns_get_family): Likewise.
19683 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
19685 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
19687 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
19689 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
19692 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
19694 Add lexical binding.
19696 * window.c (Ftemp_output_buffer_show): New fun.
19697 (Fsave_window_excursion):
19698 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
19700 * lread.c (lisp_file_lexically_bound_p): New function.
19701 (Fload): Bind Qlexical_binding.
19702 (readevalloop): Remove `evalfun' arg.
19703 Bind Qinternal_interpreter_environment.
19704 (Feval_buffer): Bind Qlexical_binding.
19705 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
19707 (syms_of_lread): Declare `lexical-binding'.
19709 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
19711 * keyboard.c (eval_dyn): New fun.
19712 (menu_item_eval_property): Use it.
19714 * image.c (parse_image_spec): Use Ffunctionp.
19716 * fns.c (concat, mapcar1): Accept byte-code-functions.
19718 * eval.c (Fsetq): Handle lexical vars.
19719 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
19720 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
19721 (FletX, Flet): Obey lexical binding.
19722 (Fcommandp): Handle closures.
19723 (Feval): New `lexical' arg.
19724 (eval_sub): New function extracted from Feval. Use it almost
19725 everywhere where Feval was used. Look up vars in lexical env.
19727 (Ffunctionp): Move from subr.el.
19728 (Ffuncall): Handle closures.
19729 (apply_lambda): Remove `eval_flags'.
19730 (funcall_lambda): Handle closures and new byte-code-functions.
19731 (Fspecial_variable_p): New function.
19732 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
19733 but without exporting it to Lisp.
19735 * doc.c (Fdocumentation, store_function_docstring):
19736 * data.c (Finteractive_form): Handle closures.
19738 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
19741 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
19743 (exec_byte_code): New function extracted from Fbyte_code to handle new
19744 calling convention for byte-code-functions. Add new byte-codes.
19746 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
19748 * alloc.c (Fmake_symbol): Init new `declared_special' field.
19750 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
19752 * xdisp.c (redisplay_internal): Fix prototype.
19754 2011-03-31 Eli Zaretskii <eliz@gnu.org>
19756 * xdisp.c (SCROLL_LIMIT): New macro.
19757 (try_scrolling): Use it when setting scroll_limit.
19758 Limit scrolling to 100 screen lines.
19759 (redisplay_window): Even when falling back on "recentering",
19760 position point in the window according to scroll-conservatively,
19761 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
19763 (try_scrolling): When point is above the window, allow searching
19764 as far as scroll_max, or one screenful, to compute vertical
19765 distance from PT to the scroll margin position. This prevents
19766 try_scrolling from unnecessarily failing when
19767 scroll-conservatively is set to a value slightly larger than the
19768 window height. Clean up the case of PT below the margin at bottom
19769 of window: scroll_max can no longer be INT_MAX. When aggressive
19770 scrolling is in use, don't let point enter the opposite scroll
19771 margin as result of the scroll.
19772 (syms_of_xdisp) <scroll-conservatively>: Document the
19773 threshold of 100 lines for never-recentering scrolling.
19775 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
19777 * dispextern.h (move_it_by_lines):

19780 (message_log_check_duplicate): Remove parameters `prev_bol' and
19781 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
19782 (redisplay_internal): Remove parameter `preserve_echo_area',
19783 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
19785 * indent.c (Fvertical_motion):
19786 * window.c (window_scroll_pixel_based, Frecenter):
19787 Don't pass `need_y_p' to `move_it_by_lines'.
19789 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
19791 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
19792 steal a few bits to be more compact.
19793 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
19794 Remove unneeded casts.
19796 * bytecode.c (Fbyte_code): CAR and CDR can GC.
19798 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
19800 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
19801 binding" message (bug#7967).
19803 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
19805 Fix more problems found by GCC 4.6.0's static checks.
19807 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
19808 Remove unused local var.
19810 * editfns.c (Fmessage_box): Remove unused local var.
19812 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
19813 (note_mode_line_or_margin_highlight, note_mouse_highlight):
19814 Omit unused local vars.
19815 * window.c (shrink_windows): Omit unused local var.
19816 * menu.c (digest_single_submenu): Omit unused local var.
19817 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
19818 Omit unused local var.
19820 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
19821 Don't assume string length fits in int.
19822 (keyremap_step, read_key_sequence): Use size_t for sizes.
19823 (read_key_sequence): Don't check last_real_key_start redundantly.
19825 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
19826 instead of alloca (Bug#8344).
19828 * eval.c (Fbacktrace): Don't assume nargs fits in int.
19829 (Fbacktrace_frame): Don't assume nframes fits in int.
19831 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
19833 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
19836 * term.c (produce_glyphless_glyph): Remove unnecessary test.
19838 * cm.c (calccost): Turn while-do into do-while, for clarity.
19840 * keyboard.c (syms_of_keyboard): Use the same style as later
19841 in this function when indexing through an array. This also
19842 works around GCC bug 48267.
19844 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
19846 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
19848 * chartab.c (sub_char_table_ref_and_range): Redo for slight
19849 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
19851 * keyboard.c, keyboard.h (num_input_events): Now size_t.
19852 This avoids undefined behavior on integer overflow, and is a bit
19853 more convenient anyway since it is compared to a size_t variable.
19855 Variadic C functions now count arguments with size_t, not int.
19856 This avoids an unnecessary limitation on 64-bit machines, which
19857 caused (substring ...) to crash on large vectors (Bug#8344).
19858 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
19859 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

19867 * fns.c (concat): Likewise.
19868 * frame.c (x_set_frame_parameters): Likewise.
19869 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
19870 0 if not found, not -1. All callers changed.
19872 * alloc.c (garbage_collect): Don't assume stack size fits in int.
19873 (stack_copy_size): Now size_t, not int.
19874 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
19876 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
19878 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
19879 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
19880 All callers changed.
19882 * lisp.h (multibyte_char_to_unibyte):
19883 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
19884 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

19895 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
19896 don't set the hook to nil, but remove the offending function instead.
19897 (Qcommand_hook_internal): Remove, unused.
19898 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
19899 Vcommand_hook_internal.
19901 * eval.c (enum run_hooks_condition): Remove.
19902 (funcall_nil, funcall_not): New functions.
19903 (run_hook_with_args): Call each function through a `funcall' argument.

19917 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
19918 All callers changed.
19920 * w32.c (_wsa_errlist): Use braces for struct initializers.
19922 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
19923 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.

20069 * term.c (Fsuspend_tty, Fresume_tty):
20070 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
20071 * window.c (temp_output_buffer_show):
20072 * insdel.c (signal_before_change):
20073 * frame.c (Fhandle_switch_frame):

20078 * callint.c (Fcall_interactively):
20079 * buffer.c (Fkill_all_local_variables):
20080 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
20082 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
20083 unconditionally since it does the check itself.
20085 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
20087 Fix more problems found by GCC 4.5.2's static checks.
20089 * coding.c (encode_coding_raw_text): Avoid unnecessary test
20090 the first time through the loop, since we know p0 < p1 then.
20091 This also avoids a gcc -Wstrict-overflow warning.
20093 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
20094 leading to a memory leak, possible in functions like
20095 load_charset_map_from_file that can allocate an unbounded number
20096 of objects (Bug#8318).
20098 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
20099 that could (at least in theory) be that large.
20101 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
20102 This is less likely to overflow, and avoids undefined behavior if
20103 overflow does occur. All callers changed. Use strtoul to scan
20104 for the unsigned long integer.
20105 (pint2hrstr): Simplify and tune code slightly.
20106 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
20108 * scroll.c (do_scrolling): Work around GCC bug 48228.
20109 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

20114 This also avoids a warning with gcc -Wstrict-overflow.
20116 * fileio.c (Fcopy_file): Report error if fchown or fchmod
20119 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
20121 * process.c (Fmake_network_process): Use socklen_t, not int,
20122 where POSIX says socklen_t is required in portable programs.
20123 This fixes a porting bug on hosts like 64-bit HP-UX, where
20124 socklen_t is wider than int (Bug#8277).
20125 (Fmake_network_process, server_accept_connection):
20126 (wait_reading_process_output, read_process_output):
20129 * process.c: Rename or move locals to avoid shadowing.

20139 Make tparam.h and terminfo.c consistent.
20140 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
20141 Include tparam.h instead, since it declares them.
20142 * cm.h (PC): Remove extern decl; tparam.h now does this.
20143 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
20144 * terminfo.c: Include tparam.h, to check interfaces.
20145 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
20146 (tparam): Adjust signature to match interface in tparam.h;
20147 this removes some undefined behavior. Check that outstring and len
20148 are zero, which they always are with Emacs.
20149 * tparam.h (PC, BC, UP): New extern decls.
20151 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
20152 (xftfont_open): Rename locals to avoid shadowing.
20154 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
20155 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.

20166 * composite.c (composition_compute_stop_pos): Rename local to
20168 (composition_reseat_it): Remove unused locals.
20169 (find_automatic_composition, composition_adjust_point): Likewise.
20170 (composition_update_it): Mark var as initialized.
20171 (find_automatic_composition): Mark vars as initialized,
20172 with a FIXME (Bug#8290).

20176 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
20177 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
20178 (BUF_DEC_POS): Be more systematic about renaming local temporaries
20179 to avoid shadowing.
20181 * textprop.c (property_change_between_p): Remove; unused.
20183 * intervals.c (interval_start_pos): Now static.
20185 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

20188 Rename locals to avoid shadowing.
20190 * sound.c (wav_play, au_play, Fplay_sound_internal):
20191 Fix pointer signedness.
20192 (alsa_choose_format): Remove unused local var.
20193 (wav_play): Initialize a variable to 0, to prevent undefined
20194 behavior (Bug#8278).
20196 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
20198 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
20200 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
20201 clobbering (Bug#8298).
20202 * sysdep.c (sys_subshell): Likewise.
20203 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
20205 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
20206 This should get cleaned up, so that child_setup has the
20207 same signature on all platforms.
20209 * callproc.c (call_process_cleanup): Now static.
20210 (relocate_fd): Rename locals to avoid shadowing.
20212 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
20214 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
20215 not to be necessary, and produces flickering.
20217 2011-03-20 Glenn Morris <rgm@gnu.org>
20219 * config.in: Remove file.
20221 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
20223 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
20224 are now in src/globals.h.
20225 (syms_of_minibuf): Remove spurious & from previous change.
20227 2011-03-20 Leo Liu <sdl.web@gmail.com>
20229 * minibuf.c (completing-read-function): New variable.
20230 (completing-read-default): Rename from completing-read.
20231 (completing-read): Call completing-read-function.
20233 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
20235 * xfaces.c (Fx_load_color_file):
20236 Read color file from absolute filename (bug#8250).
20238 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
20240 * makefile.w32-in: Update dependencies.
20242 2011-03-17 Eli Zaretskii <eliz@gnu.org>
20244 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

20251 (sigchld_handler): Now static.
20253 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
20254 That way, the code declares only the vars that it needs.
20255 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
20256 * s/cygwin.h (PTY_ITERATION): Likewise.
20257 * s/darwin.h (PTY_ITERATION): Likewise.

20264 (CONSTANTLIM): Remove; unused.
20265 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
20266 Define only if needed.
20268 * unexelf.c (unexec): Name an expression,
20269 to avoid gcc -Wbad-function-cast warning.
20270 Use a different way to cause a compilation error if anyone uses
20271 n rather than nn, a way that does not involve shadowing.
20272 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
20274 * deps.mk (unexalpha.o): Remove; unused.
20276 New file unexec.h, the (simple) interface for unexec (Bug#8267).
20277 * unexec.h: New file.
20278 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
20279 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
20280 Depend on unexec.h.
20281 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
20282 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
20283 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
20284 Change as necessary to match prototype in unexec.h.
20286 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid

20339 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
20340 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
20341 some of which prompt warnings from gcc -Wbad-function-cast.
20342 (Fformat_time_string, Fencode_time, Finsert_char):
20343 (Ftranslate_region_internal, Fformat):
20344 Rename or remove local vars to avoid shadowing.
20345 (Ftranslate_region_internal): Mark var as initialized.
20347 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
20350 * lisp.h (eassert): Check that the argument compiles, even if
20351 ENABLE_CHECKING is not defined.
20353 * data.c (Findirect_variable): Name an expression, to avoid
20354 gcc -Wbad-function-cast warning.

20363 Rename locals to avoid shadowing.
20364 (mark_stack): Move local variables into the #ifdef region where
20366 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
20367 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
20369 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
20370 (GC_STRING_CHARS): Remove; not used.
20371 (Fmemory_limit): Cast sbrk's returned value to char *.
20373 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

20379 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
20380 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
20381 to use the following functions instead of these macros.
20382 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
20383 EMACS_INT, since callers assume the returned value fits in int.
20384 (upcase1): Likewise, for UPCASE_TABLE.
20385 (uppercasep, lowercasep, upcase): New static inline functions.
20386 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

20391 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
20392 (regex_compile, re_search_2, re_match_2_internal):
20393 Remove unused local vars.
20394 (FREE_VAR): Rewrite so as not to use empty "else",
20395 which gcc can warn about.
20396 (regex_compile, re_match_2_internal): Mark locals as initialized.
20397 (RETALLOC_IF): Define only if needed.
20398 (WORDCHAR_P): Likewise. This one is never needed, but is used
20399 only in a comment talking about a compiler bug, so put inside
20400 the #if 0 of that comment.
20401 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
20402 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
20405 * search.c (boyer_moore): Rename locals to avoid shadowing.
20406 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
20407 (PREV_CHAR_BOUNDARY): Likewise.
20409 * search.c (simple_search): Remove unused var.
20411 * dired.c (compile_pattern): Move decl from here ...

20419 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
20420 Rename locals to avoid shadowing.
20421 (Fvertical_motion): Mark locals as initialized.
20423 * casefiddle.c (casify_object, casify_region): Now static.
20424 (casify_region): Mark local as initialized.
20426 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
20428 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
20429 New macros, so that the caller can use some names other than
20430 gcpro1, gcpro2, etc.
20431 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
20433 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
20434 argument, for consistency with GCPRO2_VAR, etc: it is now the
20435 prefix of the variable, not the variable itself. All uses
20437 * dired.c (directory_files_internal, file_name_completion):
20438 Rename locals to avoid shadowing.
20440 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
20441 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
20442 dired.c's scmp function, had undefined behavior.
20443 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
20444 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
20445 * buffer.h: ... to here, because these macros use current_buffer,
20446 and the new implementation with inline functions needs to have
20447 current_buffer in scope now, rather than later when the macros
20449 (downcase, upcase1): New static inline functions.
20450 (DOWNCASE, UPCASE1): Reimplement using these functions.
20451 This avoids undefined behavior in expressions like
