3 * fileio.c (Finsert_file_contents): Doc fix.
5 * w32proc.c (new_child, delete_child, find_child_pid): For a
6 subprocess, consider its slot being in use as long as its process
7 handle (procinfo.hProcess) is not NULL. This avoids reusing the
8 slot when a new process is started immediately after killing
9 another one, without waiting enough time for the first process to
10 be reaped and resources allocated for it be orderly freed.
12 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
14 2012-12-21 Chong Yidong <cyd@gnu.org>
16 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).

22 * w32.c (get_name_and_id): Always pass NULL as the first argument
23 of lookup_account_sid. Avoids crashes with UNC file names that
24 refer to DFS domains, not to specific machine names. (Bug#12621)
25 Remove now unused argument FNAME; all callers changed.
26 (get_file_owner_and_group): Remove now unused argument FNAME; all
29 2012-12-21 Chong Yidong <cyd@gnu.org>
31 * editfns.c (Finsert_char): Since read-char-by-name now signals an
32 error for invalid chars, don't check for a nil return value.
34 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
36 Avoid calls to CHAR_TO_BYTE if byte position is known.

65 * intervals.c (graft_intervals_info_buffer): Find an interval here.
67 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
69 * coding.c (Fdetect_coding_region): Do not check start and end with
70 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
71 (code_convert_region): Likewise.

88 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
89 propagate redisplay's scrolling (if any) to the right window.

120 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
122 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
123 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
124 for some of that bug's symptoms can now cause Emacs to abort.
125 Remove the workaround.
126 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
127 The bug that caused SIGCHLD to get lost has been fixed, and the
128 workaround for it can now cause Emacs to abort.
130 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
132 * sysdep.c (emacs_abort): Bump backtrace size to 40.

156 (record_infile, record_pending_deletion): New prototypes.
158 * w32proc.c (new_child): Initialize input_file and
159 pending_deletion members of the child.
160 (delete_child): Delete the child's temporary input file, if any,
161 that is pending deletion.

163 (record_infile, record_pending_deletion): New functions.
164 (reap_subprocess): Fix a typo in DebPrint string.
165 (sys_spawnve, sys_kill): Use pid_t for PID arguments.

170 * lisp.h (internal_delete_file): Adjust prototype.
172 * callproc.c (Fcall_process): Don't overwrite infile with result
174 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an

177 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
178 delete the file, record it as pending deletion when the subprocess
181 2012-12-14 Eli Zaretskii <eliz@gnu.org>
183 * editfns.c [HAVE_PWD_H]: Include grp.h.
185 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.

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

193 file-ownership-preserved-p instead, with its new group arg.
194 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.

203 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
204 try to get accurate owner and group information from NT file
205 security APIs. This is to make most callers of 'stat' and
206 'lstat', which don't need that information, much faster.
208 * dired.c (Ffile_attributes) [WINDOWSNT]:
209 Set w32_stat_get_owner_group to a non-zero value, to request accurate
210 owner and group information from 'lstat'.

214 * fileio.c (Finsert_file_contents): Don't put tail into head area,
215 as that confuses set-auto-coding, so insist on the head-read
216 returning the full 1024 bytes. Let lseek compute the tail offset;

244 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
246 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
247 fstat shouldn't fail, and if it does fail copy-file should not proceed.
248 Remove unnecessary S_ISLNK test, as (contra the comments) this
249 function can't copy symlinks. Improve quality of error message
250 when attempting to copy files that are neither regular files nor
253 2012-12-12 Dmitry Antipov <dmantipov@yandex.ru>

261 2012-12-12 Daniel Colascione <dancol@dancol.org>
263 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
264 the dumped Emacs is not a sparse file, greatly improving Cygwin
265 "make bootstrap" performance.

270 incoming inotify event.
272 2012-12-11 Eli Zaretskii <eliz@gnu.org>
274 * xdisp.c (handle_face_prop): Fix logic of computing
275 it->start_of_box_run_p.
276 (append_space_for_newline): If the glyph row is R2L, reset the
277 iterator's end_of_box_run_p flag before prepending the space glyph.
278 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
279 iterator's start_of_box_run_p flag before prepending the stretch.
280 (append_glyph, produce_image_glyph, append_composite_glyph)
281 (append_stretch_glyph, append_glyphless_glyph): Reverse the
282 left_box_line_p and right_box_line_p flags of the glyph for R2L
283 glyph rows. (Bug#13011)

295 2012-12-11 Eli Zaretskii <eliz@gnu.org>
297 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
298 encoded_file_name, which is what it is.

333 (hinst): Remove unneeded extern declaration.
334 (_start): Remove initialization of above variables; remove
335 initialization of hinst, as cache_system_info now does that.
337 * emacs.c (main): Call cache_system_info early in startup; we
338 previously weren't calling it in Cygwin builds.

505 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
507 * w32fns.c (emacs_abort): Don't do arithmetics on void pointers.
509 2012-12-08 Eli Zaretskii <eliz@gnu.org>
511 * w32.c (unsetenv, sys_putenv): New functions.
513 2012-12-08 Chong Yidong <cyd@gnu.org>
515 * editfns.c (Finsert_char): Make the error message more
516 informative (Bug#12992).
518 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
520 Simplify get_lim_data.
521 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
522 Remove USG and vlimit methods; no longer used these days.
523 Add #error catchall just in case.
525 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
526 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
527 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
528 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
529 (deleted_pid_list, Fdelete_process, create_process)
530 (record_child_status_change, handle_child_signal, deliver_child_signal)
531 (init_process_emacs, syms_of_process):
532 Assume SIGCHLD is defined.
533 (parse_signal): Remove. All uses removed.
534 (abbr_to_signal): New static function.
535 (Fsignal_process): Use it to convert signal names to ints.
536 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
537 kill (getpgrp (), ...).
538 (emacs_sigaction_init): Assume SIGCHLD is defined.
539 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,
540 SIGPIPE, and SIGQUIT are defined. Do not worry about SIGCLD any more.
541 * syssignal.h (EMACS_KILLPG): Remove.
542 All uses replaced by 'kill' with a negative pid.
543 (SIGCHLD): Remove definition, as we now assume SIGCHLD.
544 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
546 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
548 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
549 This will cause a production Emacs to dump core instead of
552 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
554 * frame.c (make_frame): Do not set window's buffer to t.
555 * window.c (Fsplit_window_internal): Likewise. Previously it was
556 used to indicate that the window is being set up. Now we use
557 set_window_buffer for all new windows, so the condition in ...
558 (Fset_window_buffer): ... is always true and can be removed.
560 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
562 Convenient macro to check whether the buffer is hidden.
563 * buffer.h (BUFFER_HIDDEN_P): New macro.
564 * frame.c (make_frame): Use it. Adjust comment.
565 * buffer.c (candidate_buffer): New function.
566 (Fother_buffer, other_buffer_safely): Use it.
568 2012-12-06 Eli Zaretskii <eliz@gnu.org>
570 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
571 if the child process is still running. Instead, exit the wait
572 loop and return zero. (Bug#13086)
574 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
576 * frame.h (x_char_width, x_char_height): Remove prototypes.

585 (command_loop_2, top_level_1): Add static to match prototype.
587 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
589 Fix a recently-introduced delete-process race condition.
590 * callproc.c, process.h (record_kill_process):
591 New function, containing part of the old call_process_kill.
592 (call_process_kill): Use it.
593 This does not change call_process_kill's behavior.
594 * process.c (Fdelete_process): Use record_kill_process to fix a
595 race condition that could cause Emacs to lose track of a child.
597 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
599 Avoid code duplication between prev_frame and next_frame.
600 * frame.c (candidate_frame): New function. Add comment.
601 (prev_frame, next_frame): Use it. Adjust comment.
603 2012-12-06 Eli Zaretskii <eliz@gnu.org>
605 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
606 fails, signal an error instead of continuing with an empty
608 Encode expanded temp file pattern before passing it to mkstemp or
611 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
612 Encode the file name before passing it to dostounix_filename, in
613 case it will downcase it (under w32-downcase-file-names).
616 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
618 Minor call-process cleanups.
619 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
620 at the same time as other platforms, to simplify analysis.
621 No need for fd0_volatile since we have synch_process_fd.
622 Avoid needless emacs_close; arg is always negative.
624 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
626 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
629 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
631 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
632 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
633 and mouse_face_hidden members to a bitfields.
634 * frame.h (struct frame): Remove set-but-not-used space_width member.
635 (FRAME_SPACE_WIDTH): Remove.
636 * nsterm.m, w32term.c, xterm.c: Adjust users.
637 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
638 member. Adjust users. Convert term_initted, delete_in_insert_mode,
639 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
640 members to a bitfields.
642 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
644 Don't let call-process be a zombie factory (Bug#12980).
645 Fixing this bug required some cleanup of the signal-handling code.
646 As a side effect, this change also fixes a longstanding rare race
647 condition whereby Emacs could mistakenly kill unrelated processes,
648 and it fixes a bug where a second C-g does not kill a recalcitrant
649 synchronous process in GNU/Linux and similar platforms.
650 The patch should also fix the last vestiges of Bug#9488,
651 a bug which has mostly been fixed on the trunk by other changes.
652 * callproc.c, process.h (synch_process_alive, synch_process_death)
653 (synch_process_termsig, sync_process_retcode):
654 Remove. All uses removed, to simplify analysis and so that
655 less consing is done inside critical sections.
656 * callproc.c (call_process_exited): Remove. All uses replaced
657 with !synch_process_pid.
658 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
659 These take the role of what used to be in unwind-protect arg.
661 (block_child_signal, unblock_child_signal):
662 New functions, to avoid races that could kill innocent-victim processes.
663 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
664 (call_process_kill): Record killed processes as deleted, so that
665 zombies do not clutter up the system. Do this inside a critical
666 section, to avoid a race that would allow the clutter.
667 (call_process_cleanup): Fix code so that the second C-g works again
668 on common platforms such as GNU/Linux.
669 (Fcall_process): Create the child process in a critical section,
670 to fix a race condition. If creating an asynchronous process,
671 record it as deleted so that zombies do not clutter up the system.
672 Do unwind-protect for WINDOWSNT too, as that's simpler in the
673 light of these changes. Omit unnecessary call to emacs_close
674 before failure, as the unwind-protect code does that.
675 * callproc.c (call_process_cleanup):
676 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
677 * process.c (record_deleted_pid): New function, containing
678 code refactored out of Fdelete_process.
679 (Fdelete_process): Use it.
680 (process_status_retrieved): Remove. All callers changed to use
682 (record_child_status_change): Remove, folding its contents into ...
683 (handle_child_signal): ... this signal handler. Now, this
684 function is purely a handler for SIGCHLD, and is not called after
685 a synchronous waitpid returns; the synchronous code is moved to
686 wait_for_termination. There is no need to worry about reaping
687 more than one child now.
688 * sysdep.c (get_child_status, child_status_changed): New functions.
689 (wait_for_termination): Now takes int * status and bool
690 interruptible arguments, too. Do not record child status change;
691 that's now the caller's responsibility. All callers changed.
692 Reimplement in terms of get_child_status.
693 (wait_for_termination_1, interruptible_wait_for_termination):
694 Remove. All callers changed to use wait_for_termination.
695 * syswait.h: Include <stdbool.h>, for bool.
696 (record_child_status_change, interruptible_wait_for_termination):
698 (record_deleted_pid, child_status_changed): New decls.
699 (wait_for_termination): Adjust to API changes noted above.
701 * bytecode.c, lisp.h (Qbytecode): Remove.
702 No longer needed after 2012-11-20 interactive-p changes.
704 2012-12-03 Eli Zaretskii <eliz@gnu.org>
706 * xdisp.c (redisplay_window): If the cursor is visible, but inside
707 the scroll margin, move point outside the margin. (Bug#13055)
709 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
711 * gtkutil.c (my_log_handler): New function.
712 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
714 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
716 * lisp.h (modify_region): Rename to...
717 (modify_region_1): ...new prototype.
718 * textprop.c (modify_region): Now static. Adjust users.
719 * insdel.c (modify_region): Rename to...
720 (modify_region_1): ...new function to work with current buffer.
721 Adjust comment and users. Use true and false for booleans.
723 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
725 * alloc.c (free_save_value): New function.
726 (safe_alloca_unwind): Use it.
727 * lisp.h (free_save_value): New prototype.
728 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
730 (save_excursion_restore): Adjust to match saved data structure.
731 Use free_save_value to offload some work from GC. Drop obsolete
734 2012-12-03 Chong Yidong <cyd@gnu.org>
736 * fileio.c (Vauto_save_list_file_name): Doc fix.
738 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
740 * w32fns.c: Remove prototype of atof.
741 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
743 (file_dialog_callback): Make it UINT_PTR.
745 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
748 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
749 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
752 2012-12-03 Glenn Morris <rgm@gnu.org>
754 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
756 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
758 Fix xpalloc confusion after memory is exhausted.
759 * alloc.c (xpalloc): Comment fix.
760 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
761 and signals an error, do not clear charset_table_size, as
762 charset_table is still valid.
763 * doprnt.c (evxprintf): Clear *BUF after freeing it.
765 Use execve to avoid need to munge environ (Bug#13054).
766 * callproc.c (Fcall_process):
767 * process.c (create_process):
768 Don't save and restore environ; no longer needed.
769 * callproc.c (child_setup):
770 Use execve, not execvp, to preserve environ.
772 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
774 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
776 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
778 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
779 display for sliced images (Bug#10500).
781 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
783 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
785 * doc.c (Fdocumentation): Re-add handling of function-documentation,
786 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
788 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
790 * xdisp.c (window_outdated): Remove eassert since it hits
791 some suspicious corner cases (see Bug#13007 and Bug#13012).
792 (mode_line_update_needed): New function.
793 (redisplay_internal, redisplay_window): Use it.
794 (ensure_selected_frame): New function.
795 (redisplay_internal, unwind_redisplay): Use it.
796 (redisplay_internal): Move comment about buffer_shared...
797 (buffer_shared_and_changed): ...near to its real use.
799 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
801 * callproc.c (Fcall_process): Don't misreport vfork failure.
803 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
805 * callproc.c (Fcall_process): Fix vfork portability problems.
806 Do not assume that fd[0], count, filefd, and save_environ survive
807 vfork. Fix bug whereby wrong errno value could be reported for
808 pipe failure. Some minor cleanups, too, as follows. Move buf and
809 bufsize to the context where they're needed. Change new_argv to
810 be of type char **, as this is more convenient and avoids casts.
811 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
812 Now local constants, not macros.
814 2012-11-18 Kenichi Handa <handa@gnu.org>
816 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
817 for the variable "f".
819 2012-11-13 Kenichi Handa <handa@gnu.org>
821 * font.c (font_unparse_xlfd): Exclude special characters from the
822 generating XLFD name.
824 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
826 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.
827 * dired.c (stat_uname, stat_gname):

840 * unexcoff.c (write_segment): Assume EFAULT is defined.
842 2012-11-27 Eli Zaretskii <eliz@gnu.org>
844 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
847 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
848 highlighting on the frame was cleared. Prevents assertion
849 violations when repeatedly clicking on the "Top" link of the
850 "bread-crumbs" in Info buffers.

862 2012-11-24 Eli Zaretskii <eliz@gnu.org>
864 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
865 between bpos_covered and bpos_max. This fixes cursor display when
866 several display strings follow each other.
868 * .gdbinit (pgx): If the glyph's object is a string, display the
869 pointer to string data, rather than the value of the string object
870 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
872 * indent.c (Fvertical_motion): If the starting position is covered
873 by a display string, return to one position before that, to avoid
874 overshooting it inside move_it_to. (Bug#12930)
876 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
878 * frame.h (struct frame): Remove display_preempted member

886 asked_for_visible and menubar_active members.
887 Drop unused pending_menu_activation member.
888 * xterm.h (struct x_output): Drop outdated #if 0 code.
889 Use bitfields for explicit_parent, asked_for_visible,
890 has_been_visible and net_wm_state_hidden_seen members.
892 2012-11-23 Eli Zaretskii <eliz@gnu.org>

895 of a literal "/". (Bug#12955)
896 (gl-stamp): Invoke fc.exe directly, not through cmd.
898 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>

901 * dired.c: Assume HAVE_DIRENT_H.
902 (NAMLEN): Remove, replacing with ...
903 (dirent_namelen): New function. All uses changed. Use the GNU macro
904 _D_EXACT_NAMELEN if available, as it's faster than strlen.
905 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
906 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
907 * makefile.w32-in (DIR_H): Remove. All uses replaced with
909 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
910 * ndir.h: Rename to ../nt/inc/dirent.h.
911 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
912 Do not include <dirent.h>; no longer needed.
913 * w32.c: Include <dirent.h> rather than "ndir.h".
915 2012-11-23 Chong Yidong <cyd@gnu.org>
917 * xftfont.c (xftfont_open): Remove duplicate assignment.
919 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
921 * alloc.c (Fgarbage_collect): Unblock input after clearing
922 gc_in_progress to avoid note_mouse_highlight glitch with GC.
923 * frame.h (FRAME_MOUSE_UPDATE): New macro.
924 * msdos.c (IT_frame_up_to_date): Use it here...
925 * w32term.c (w32_frame_up_to_date): ...here...
926 * xterm.c (XTframe_up_to_date): ...and here...
927 * nsterm.m (ns_frame_up_to_date): ...but not here.
928 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
930 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
931 Do not check whether GC is in progress.
933 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
935 * xdisp.c (window_buffer_changed): New function.
936 (update_menu_bar, update_tool_bar): Use it to
937 simplify large 'if' statements.
938 (redisplay_internal): Generalize commonly used
939 'tail' and 'frame' local variables.
941 2012-11-22 Eli Zaretskii <eliz@gnu.org>
943 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
944 with Windows system header.
946 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
948 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
949 * alloc.c: Assume unistd.h exists.
950 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
951 * sysdep.c (get_current_dir_name): Assume getcwd exists.
952 (getwd) [USG]: Remove; no longer needed.
953 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.

965 * emacs.c (main): Set the G_SLICE environment variable for all
966 Cygwin builds, not just GTK builds. See
967 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
969 2012-11-21 Eli Zaretskii <eliz@gnu.org>
971 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
972 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
973 Define for the MSVC compiler.
975 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
977 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
978 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
979 dostounix_filename. Prevents crashes down the road, because

988 * lread.c (init_obarray): Set `function' fields to Qnil.
989 * eval.c (Fcommandp): Ignore Qunbound.

991 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
992 Test NILP rather than Qunbound.
993 (Ffmakunbound): Set to Qnil.
994 (Fsymbol_function): Never signal an error.
995 (Finteractive_form): Ignore Qunbound.
997 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
999 * eval.c (interactive_p): Remove no-longer-used decl.
1001 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
1003 * xdisp.c (buffer_shared): Adjust comment.
1004 (buffer_shared_and_changed): New function.
1005 (prepare_menu_bars, redisplay_internal): Use it to
1006 decide whether all windows or frames should be updated.
1007 (window_outdated): New function.
1008 (text_outside_line_unchanged_p, redisplay_window): Use it.
1009 (redisplay_internal): Likewise. Fix indentation.
1011 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
1013 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
1014 (syms_of_eval): Remove corresponding defsubr.
1015 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
1017 2012-11-19 Daniel Colascione <dancol@dancol.org>
1019 * w32fns.c (Fx_file_dialog):
1020 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
1021 cygwin_convert_file_name*.
1023 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
1024 Rename cygwin_convert_path* to cygwin_convert_file_name*.
1026 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
1028 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
1030 2012-11-18 Eli Zaretskii <eliz@gnu.org>
1032 * w32select.c: Include w32common.h before w32term.h, so that
1033 windows.h gets included before w32term.h uses some of its
1034 features, see below.
1036 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
1038 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
1040 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
1042 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
1044 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
1045 (ns_select): Return at once if events are held (Bug#12834).
1047 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
1049 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
1050 Needed following 2012-10-20 change. (Bug#12902)
1052 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
1054 * w32proc.c (waitpid): Remove unused label get_result.
1056 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
1058 * makefile.w32-in (SYSWAIT_H): New macro.
1059 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
1060 ($(BLD)/sysdep.$(O)): Update dependencies.
1062 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
1064 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
1065 * callproc.c (relocate_fd): Assume F_DUPFD.
1066 * emacs.c, term.c (O_RDWR): Remove.
1067 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
1068 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
1069 * nsterm.m: Assume <fcntl.h> exists.
1070 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
1071 (create_pty, Fmake_network_process, server_accept_connection)
1072 (wait_reading_process_output, init_process_emacs):
1074 (wait_reading_process_output): Put in a special case for WINDOWSNT
1075 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
1076 It's not clear this is needed, but it's a more-conservative change.
1077 (create_process): Assume FD_CLOEXEC.
1078 (create_process, create_pty): Assume O_NOCTTY.
1079 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
1080 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
1081 Omit if not DOS_NT, since F_GETFL is not defined there.
1082 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
1083 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
1085 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
1086 lack it, since gnulib guarantees this.
1087 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
1089 2012-11-17 Eli Zaretskii <eliz@gnu.org>
1091 * w32.c (faccessat): Pretend that directories have the execute bit
1092 set. Emacs expects that, e.g., in files.el:cd-absolute.
1094 * w32proc.c (create_child): Don't clip the PID of the child
1095 process to fit into an Emacs integer, as this is no longer a
1097 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
1098 reaping only the process specified by PID argument, if that is
1099 positive. Use PID instead of dead_child to know which process to
1100 reap. Wait for the child to die only if WNOHANG is not in
1102 (sys_select): Don't set dead_child.
1104 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
1105 as it is no longer needed.
1107 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
1109 (record_child_status_change): Remove the setting of
1110 record_at_most_one_child for the !WNOHANG case.
1112 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
1114 Fix problems in ns port found by static checking.
1115 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
1116 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
1117 not to process group.
1118 (ns_select): Use emacs_write, not write, as that's more robust
1119 in the presence of signals.
1120 (fd_handler:): Check for read errors.
1122 2012-11-16 Glenn Morris <rgm@gnu.org>
1124 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
1126 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
1128 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
1130 2012-11-16 Eli Zaretskii <eliz@gnu.org>
1132 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
1133 use the same value of thread handle.
1134 (start_timer_thread): If the timer thread exited (due to error),
1135 clean up by closing the two handles it used. Duplicate the caller
1136 thread's handle here, so it gets duplicated only once, when
1137 launching the timer thread. Set priority of the timer thread, not
1139 (getitimer): Don't duplicate the caller thread's handle here.
1142 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
1144 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
1147 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
1149 Remove no-longer-used pty_max_bytes variable.
1150 * process.c (pty_max_bytes): Remove; unused.
1151 (send_process): Do not set it.
1153 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
1155 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
1156 Update dependencies.
1158 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
1160 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
1161 This follows up on the 2012-09-29 patch that removed indirection
1162 for the 'function' field. Reported by Sergey Vinokurov in
1163 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
1165 2012-11-14 Eli Zaretskii <eliz@gnu.org>
1167 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
1168 different name, as the MS runtime does not have such a function,
1169 and probably never will.) All callers changed. Ignore DIRFD
1170 value if PATH is an absolute file name, to match Posix spec
1171 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
1174 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
1176 * xdisp.c (echo_area_display, redisplay_internal):
1177 Omit redundant check whether frame_garbaged is set.
1179 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
1181 Use faccessat, not access, when checking file permissions (Bug#12632).
1182 This fixes a bug that has been present in Emacs since its creation.
1183 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
1184 which must set some sort of record. (Torek's bug report was against
1185 a predecessor of GNU Emacs, but GNU Emacs happened to have the
1186 same common flaw.) See Torek's Usenet posting
1187 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
1188 Posted: Fri Apr 8 14:18:56 1983.
1189 * Makefile.in (LIB_EACCESS): New macro.
1191 * callproc.c (init_callproc):
1192 * charset.c (init_charset):
1193 * fileio.c (check_existing, check_executable, check_writable)
1195 * lread.c (openp, load_path_check):
1196 * process.c (allocate_pty):
1198 Use effective UID when checking permissions, not real UID.
1199 * callproc.c (init_callproc):
1200 * charset.c (init_charset):
1201 * lread.c (load_path_check, init_lread):
1202 Test whether directories are accessible, not merely whether they exist.
1203 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
1204 * fileio.c (check_existing, check_executable, check_writable)
1206 Use symbolic names instead of integers for the flags, as they're
1208 (check_writable): New arg AMODE. All uses changed.
1209 Set errno on failure.
1210 (Ffile_readable_p): Use faccessat, not stat + open + close.
1211 (Ffile_writable_p): No need to call check_existing + check_writable.
1212 Just call check_writable and then look at errno. This saves a syscall.
1213 dir should never be nil; replace an unnecessary runtime check
1214 with an eassert. When checking the parent directory of a nonexistent
1215 file, check that the directory is searchable as well as writable, as
1216 we can't create files in unsearchable directories.
1217 (file_directory_p): New function, which uses 'stat' on most platforms
1218 but faccessat with D_OK (for efficiency) if WINDOWSNT.
1219 (Ffile_directory_p, Fset_file_times): Use it.
1220 (file_accessible_directory_p): New function, which uses a single
1221 syscall for efficiency.
1222 (Ffile_accessible_directory_p): Use it.
1223 * xrdb.c (file_p): Use file_directory_p.
1224 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
1225 * lread.c (openp): When opening a file, use fstat rather than
1226 stat, as that avoids a permissions race. When not opening a file,
1227 use file_directory_p rather than stat.
1228 (dir_warning): First arg is now a usage string, not a format.
1229 Use errno. All uses changed.
1230 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
1231 that merely introduced a race.
1232 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
1233 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
1234 and similarly for the other O_* flags.
1235 * w32.c (sys_faccessat): Rename from sys_access and switch to
1236 faccessat's API. All uses changed.
1237 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
1238 (magic_db): Rename from magic_file_p.
1239 (magic_db, search_magic_path): Return an XrmDatabase rather than a
1240 char *, so that we don't have to test for file existence
1241 separately from opening the file for reading. This removes a race
1242 fixes a permission-checking problem, and simplifies the code.
1244 (file_p): Remove; no longer needed.
1246 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
1248 Omit glyphs initialization at startup.
1249 * dispnew.c (glyphs_initialized_initially_p): Remove.
1250 (adjust_frame_glyphs_initially): Likewise. Adjust users.
1251 (Fredraw_frame): Move actual code from here...
1252 (redraw_frame): ...to here. Add eassert. Adjust comment.
1253 (Fredraw_display): Use redraw_frame.
1254 * xdisp.c (clear_garbaged_frames): Likewise.
1256 2012-11-13 Eli Zaretskii <eliz@gnu.org>
1258 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
1259 passed to pint2str and pint2hrstr to be at most the size of the
1260 frame's decode_mode_spec_buffer. This avoids crashes with very
1261 large values of FIELD_WIDTH argument to decode_mode_spec.
1264 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
1266 Fix a race with verify-visited-file-modtime (Bug#12863).
1267 Since at least 1991 Emacs has ignored an mtime difference of no
1268 more than one second, but my guess is that this was to work around
1269 file system bugs that were fixed long ago. Since the race is
1270 causing problems now, let's remove that code.
1271 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
1272 whose time stamp is off by no more than a second. Insist that the
1273 file time stamps match exactly.
1275 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1277 * frame.h (struct frame): Convert external_tool_bar member to
1278 1-bit unsigned bitfield.
1279 * termhooks.h (struct terminal): Remove mouse_moved member since
1280 all users are long dead. Adjust comment on mouse_position_hook.
1282 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1284 Simplify by using FOR_EACH_FRAME here and there.
1285 * frame.c (next_frame, prev_frame, other_visible_frames)
1286 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
1287 * w32term.c (x_window_to_scroll_bar): Likewise.
1288 * window.c (window_list): Likewise.
1289 * xdisp.c (x_consider_frame_title): Likewise.
1290 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
1291 * xfns.c (x_window_to_frame, x_any_window_to_frame)
1292 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
1293 * xmenu.c (menubar_id_to_frame): Likewise.
1294 * xselect.c (frame_for_x_selection): Likewise.
1295 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
1296 (x_window_to_menu_bar): Likewise.
1297 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
1299 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
1301 * data.c (Qdefalias_fset_function): Now static.
1303 Another tweak to vectorlike_header change.
1304 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
1305 Remove, and replace all uses with ...
1306 (next_in_free_list, set_next_in_free_list):
1307 New functions, which respect C's aliasing rules better.
1309 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
1311 * window.c (list4i): Rename from 'quad'. All uses changed.
1312 Needed because <sys/types.h> defines 'quad' on Solaris 10.
1314 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
1316 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
1317 warning about mixing declarations and code in ISO C90.
1319 2012-11-10 Martin Rudalics <rudalics@gmx.at>
1321 * window.c (Fsplit_window_internal): Set combination limit of
1322 new parent window to t iff Vwindow_combination_limit is t;
1323 fixing a regression introduced with the change from 2012-09-22.
1324 (Fset_window_combination_limit): Fix doc-string.
1326 2012-11-10 Eli Zaretskii <eliz@gnu.org>
1328 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
1329 amount when the scroll margins are too large. When scrolling
1330 backwards in the buffer, give up if cannot reach point or the
1331 scroll margin within a reasonable number of screen lines.
1332 Fixes point position in window under scroll-up/down-aggressively when
1333 point is positioned many lines beyond the window top/bottom.
1336 * ralloc.c (relinquish): If real_morecore fails to return memory
1337 to the system, don't crash; instead, leave the last heap
1338 unchanged and return. (Bug#12774)
1340 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1342 * lisp.h (AUTOLOADP): New macro.
1343 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
1344 * data.c (Ffset): Remove special ad-advice-info handling.
1345 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
1347 (Finteractive_form): Simplify.
1348 (Fquo): Don't insist on having at least 2 arguments.
1349 (Qdefalias_fset_function): New var.
1351 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1353 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
1355 * nsfont.m (Qcondensed, Qexpanded): New variables.
1356 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
1357 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
1359 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1361 Fix recently introduced crash on MS-Windows (Bug#12839).
1362 * w32term.h (struct scroll_bar): Use convenient header.
1363 (SCROLL_BAR_VEC_SIZE): Remove.
1364 * w32term.c (x_scroll_bar_create): Use VECSIZE.
1366 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1368 Tweak last vectorlike_header change.
1369 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
1370 vectorlike object on the free list. This is introduced to avoid
1371 some (but not all) pointer casting and aliasing problems, see
1372 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
1373 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
1375 (xvectype, xvecsize): Use them to examine Lisp_Object values.
1377 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1379 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
1380 been removed, so remove them here also.
1382 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1384 * doc.c (Fdocumentation): Handle new property
1385 dynamic-docstring-function to replace the old ad-advice-info.
1387 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
1389 * fns.c (Qeql, hashtest_eq): Now static.
1391 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1393 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
1394 * fns.c (hashfn_eq, hashfn_eql, sxhash):
1395 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
1396 * buffer.c (compare_overlays): Use XLI rather than XHASH.
1398 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
1400 Use same hash function for hashfn_profiler as for hash_string etc.
1401 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
1402 * lisp.h (sxhash_combine): New inline function, with the contents
1403 of the old SXHASH_COMBINE.
1404 * profiler.c (hashfn_profiler): Use it, instead of having a
1405 special hash function containing a comparison that always yields 1.
1407 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1409 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
1410 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
1411 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
1414 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
1416 * image.c (xpm_make_color_table_h): Fix compiler error because
1417 make_hash_table changed.
1419 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
1421 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
1423 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1425 Use ad-hoc comparison function for the profiler's hash-tables.
1426 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
1427 (make_log): Use them.
1428 (handle_profiler_signal): Don't inhibit quit any longer since we don't
1429 call Fequal any more.
1430 (Ffunction_equal): New function.
1431 (cmpfn_profiler, hashfn_profiler): New functions.

1438 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
1439 (hash_lookup, hash_remove_from_table): Move assertion checking of
1440 hashfn result here. Check hash-equality before calling cmpfn.
1441 (Fmake_hash_table): Adjust call to make_hash_table.
1442 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.
1443 (syms_of_fns): Initialize them.

1448 * composite.c (composition_gstring_put_cache): Adjust to new hashfn.
1450 2012-11-08 Eli Zaretskii <eliz@gnu.org>
1452 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
1453 value of w32-scroll-lock-modifier is neither nil nor one of the
1454 known key modifiers. (Bug#12806)
1456 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
1458 Shrink struct vectorlike_header to the only size field.
1459 * lisp.h (enum pvec_type): Avoid explicit enum member values.
1461 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
1462 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
1463 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
1464 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
1465 information from the vector header. Adjust comment.

1475 (enum mem_type): Adjust comment.
1476 (NEXT_IN_FREE_LIST): New macro.
1477 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
1478 (Fmake_bool_vector): Likewise.
1479 (struct large_vector): New type to represent allocation unit for
1480 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
1481 (large_vectors): Change type to struct large_vector.
1482 (allocate_vector_from_block): Simplify.
1483 (PSEUDOVECTOR_NBYTES): Replace with...
1484 (vector_nbytes): ...new function. Adjust users.
1485 (sweep_vectors): Adjust processing of large vectors.
1486 (allocate_vectorlike): Likewise.
1487 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
1488 Add easserts. Adjust XSETPVECTYPESIZE usage.
1489 (allocate_buffer): Use BUFFER_PVEC_INIT.
1490 (live_vector_p): Adjust to match large vector.
1491 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
1492 * buffer.h (struct buffer): Add next member.
1493 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
1495 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
1496 * fns.c (internal_equal): Adjust to match enum pvec_type change.
1497 (copy_hash_table): Adjust to match vector header change.

1501 (xvecsize): New command.
1503 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
1505 * keyboard.c (event_to_kboard): Do not dereference
1506 frame_or_window field of SELECTION_REQUEST_EVENT
1507 and SELECTION_CLEAR_EVENT events (Bug#12814).
1508 * xterm.h (struct selection_input_event): Adjust comment.
1510 2012-11-07 Eli Zaretskii <eliz@gnu.org>
1512 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
1513 such as Scroll Lock, if the respective keys are treated as
1514 function keys, not as modifiers. This avoids destroying non-ASCII
1515 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
1517 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
1519 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
1521 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1523 Restore some duplicate definitions (Bug#12814).
1524 This undoes part of the 2012-11-03 changes. Some people build
1525 with plain -g rather than with -g3, and they need the duplicate
1526 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
1527 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
1528 Define as macros, as well as as enums or as constants.
1530 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
1532 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
1533 to keypad keys (Bug#12816).
1535 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1537 Minor adjustments of recently-changed frame functions.
1538 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
1539 known to be a frame (we're in the FRAMEP branch).
1540 * lisp.h (Qframep): Remove decl. frame.h declares this.
1541 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
1542 since they're meant for Lisp fixnum values.
1544 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1546 * window.c (Fwindow_combination_limit): Revert to the only
1547 required argument and adjust docstring as suggested in
1548 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
1549 by Martin Rudalics <rudalics@gmx.at>.
1551 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1553 Widely used frame validity and checking functions.
1554 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
1555 * frame.c (decode_live_frame, decode_any_frame): New functions.
1556 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
1557 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
1558 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
1559 (Fframe_pointer_visible_p): Use decode_any_frame.

1561 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
1562 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
1563 (Fframe_focus): Likewise. Allow zero number of arguments.
1565 (frame_buffer_list, frame_buffer_predicate): Remove.
1566 * lisp.h (frame_buffer_predicate): Remove prototype.
1567 * buffer.c (Fother_buffer): Use decode_any_frame.
1568 * xdisp.c (Ftool_bar_lines_needed): Likewise.
1569 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
1570 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
1571 (Fclose_font, Ffont_info): Use decode_live_frame.
1572 * fontset.c (check_fontset_name): Likewise.
1573 * terminal.c (Fframe_terminal): Likewise.
1574 * w32fns.c (check_x_frame): Likewise.
1575 * window.c (Fminibuffer_window, Fwindow_at)
1576 (Fcurrent_window_configuration): Likewise.
1577 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
1578 Likewise. Allow zero number of arguments. Adjust docstring.
1579 * dispnew.c (Fredraw_frame): Likewise.
1580 * xfaces.c (frame_or_selected_frame): Remove.
1581 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
1582 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
1583 (Fframe_face_alist): Use decode_live_frame.
1584 * xfns.c (check_x_frame): Likewise.
1586 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1588 * window.c (quad): New function.
1589 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
1590 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
1591 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
1592 (Fwindow_line_height): Use it.
1593 (Fwindow_fringes): Use list3.
1594 (Fwindow_scroll_bars): Use list4.
1595 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
1596 (Fwindow_combination_limit): Allow zero number of arguments.
1598 2012-11-05 Eli Zaretskii <eliz@gnu.org>
1600 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
1602 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
1603 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
1604 file descriptor 2 for standard error. (Bug#12805)
1606 2012-11-05 Chong Yidong <cyd@gnu.org>
1608 * process.c (wait_reading_process_output): Revert previous change.
1610 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
1612 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
1613 This removes code that has been obsolete since around 1990.
1614 * callproc.c (Fcall_process):
1616 * process.c (create_process):
1617 * term.c (dissociate_if_controlling_tty):
1618 Assume setsid exists.
1619 * callproc.c (child_setup): Assume setpgid exists and behaves as
1620 per POSIX.1-1988 or later.
1621 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
1622 * emacs.c (shut_down_emacs):
1623 * sysdep.c (sys_suspend, init_foreground_group):
1624 Assume getpgrp behaves as per POSIX.1-1998 or later.
1625 * msdos.c (setpgrp): Remove.
1626 (tcgetpgrp, setpgid, setsid): New functions.
1627 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
1628 * term.c (no_controlling_tty): Remove; unused.
1629 * w32proc.c (setpgrp): Remove.
1630 (setsid, tcgetpgrp): New functions.
1632 Simplify by assuming __fpending.
1633 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
1634 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
1635 Do not assume that __fpending's result fits in int.
1637 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
1639 Remove EMACS_OUTQSIZE+sleep hack.
1640 * dispnew.c (update_frame_1): Remove hack for terminals slower
1641 than 2400 bps, which throttled Emacs by having it sleep.
1642 This code hasn't worked since at least 2007, when the multi-tty stuff
1643 was added, and anyway those old terminals are long dead.
1644 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
1645 without the dispnew.c change, as dispnew.c doesn't include systty.h.
1647 Fix data-loss with --version (Bug#9574).
1648 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
1649 as we can't assume that emacs_strerror is initialized, and strerror
1650 is good enough here.
1651 (main): Invoke atexit earlier, to catch earlier instances of
1652 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
1654 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
1656 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
1657 (keyDown): Remap keypad keys to X11 virtual key codes.
1659 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
1661 Fix data-loss with --batch (Bug#9574).
1662 * emacs.c: Include <close-stream.h>.
1663 (close_output_streams): New function.
1664 (main): Pass it to atexit, so that Emacs closes stdout and stderr
1665 and handles errors appropriately.
1666 (Fkill_emacs): Don't worry about flushing, as close_output_stream
1669 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
1670 The symptom is a diagnostic "GLib-WARNING **: In call to
1671 g_spawn_sync(), exit status of a child process was requested but
1672 SIGCHLD action was set to SIG_IGN and ECHILD was received by
1673 waitpid(), so exit status can't be returned." The diagnostic
1674 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
1675 The real bug is a race condition between Emacs and glib: Emacs
1676 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
1677 so that glib can't find it. Work around the bug by invoking
1678 waitpid only on subprocesses that Emacs itself creates.
1679 * process.c (create_process, record_child_status_change):
1680 Don't use special value -1 in pid field, as the caller now must
1681 know the pid rather than having the callee infer it.
1682 The inference was sometimes incorrect anyway, due to another race.
1683 (create_process): Set new 'alive' member if child is created.
1684 (process_status_retrieved): New function.
1685 (record_child_status_change): Use it.
1686 Accept negative 1st argument, which means to wait for the
1687 processes that Emacs already knows about. Move special-case code
1688 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
1689 processes that have already been waited for, by testing and
1690 clearing new 'alive' member.
1691 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
1692 now does this internally.
1693 (handle_child_signal): Let record_child_status_change do all
1694 the work, since we do not want to reap all exited child processes,
1695 only the child processes that Emacs itself created.
1696 * process.h (Lisp_Process): New boolean member 'alive'.
1698 Omit duplicate definitions no longer needed with gcc -g3.
1699 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
1700 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
1701 Define only as macros. There's no longer any need to also define
1702 these symbols as enums or as constants, since we now assume
1703 gcc -g3 when debugging.
1705 2012-11-03 Eli Zaretskii <eliz@gnu.org>
1707 * lisp.mk: Adjust comments to the fact that term/internal is now
1708 loaded from loadup.el.
1710 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
1711 (msdos_fatal_signal): New function.
1712 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
1715 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
1716 for GCC versions before 4.
1717 (emacs_raise): Define to call msdos_fatal_signal.
1719 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
1720 iterator when starting in the middle of a display or overlay
1723 2012-11-03 Chong Yidong <cyd@gnu.org>
1725 * process.c (wait_reading_process_output): Clean up the last
1728 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
1730 * process.c (wait_reading_process_output): Avoid a race condition
1731 with SIGIO delivery (Bug#11536).
1733 2012-11-03 Chong Yidong <cyd@gnu.org>
1735 * buffer.c (cursor_type): Untabify docstring.
1737 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1739 * frame.h (struct frame): Drop can_have_scroll_bars member
1740 which is meaningless for a long time. Adjust comments.
1741 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
1742 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
1744 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1746 * window.c (decode_next_window_args): Update window arg after
1747 calling decode_live_window and so fix crash reported at
1748 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
1749 by Juanma Barranquero <lekktu@gmail.com>.
1750 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
1751 * font.c (Ffont_at): Likewise.
1753 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
1755 * widget.c (resize_cb): New function.
1756 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
1757 (EmacsFrameResize): Check if all is up to date before changing frame
1760 2012-11-02 Eli Zaretskii <eliz@gnu.org>
1762 Implement backtrace output for fatal errors on MS-Windows.
1763 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
1764 (BACKTRACE_LIMIT_MAX): New macro.
1765 (w32_backtrace): New function.
1766 (emacs_abort): Use w32_backtrace when the user chooses not to
1767 attach a debugger. Update the text of the abort dialog.
1769 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1771 Window-related stuff cleanup here and there.
1772 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
1773 Use decode_any_window.
1774 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
1775 * xdisp.c (Fformat_mode_line): Likewise.
1776 * font.c (Ffont_at): Use decode_live_window.
1777 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
1778 * window.c (decode_next_window_args): Likewise.
1779 (decode_any_window): Remove static.
1780 * window.h (decode_any_window): Add prototype.
1781 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
1782 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
1785 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1787 Remove pad from struct input_event.
1788 * termhooks.h (struct input_event): Remove padding field.
1790 * keyboard.c (event_to_kboard): Simplify because frame_or_window
1791 member is never cons for a long time. Adjust comment.
1792 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
1793 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
1794 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
1795 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
1797 2012-11-01 Eli Zaretskii <eliz@gnu.org>
1799 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
1801 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
1803 Fix crash when using Emacs as commit editor for git (Bug#12697).
1804 * callproc.c (setpgrp): Remove macro, as we now use setpgid
1805 and it is configured in conf_post.h.
1806 (Fcall_process): Don't invoke both setsid and setpgid; the former
1807 is enough, if it exists.
1808 * callproc.c (Fcall_process, child_setup):
1809 * process.c (create_process): Use setpgid.
1810 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
1812 * dispnew.c (init_display): Initialize the foreground group
1813 if we are running a tty display.
1814 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
1815 * lisp.h (init_foreground_group): New decl.
1816 * sysdep.c (inherited_pgroup): New static var.
1817 (init_foreground_group, tcsetpgrp_without_stopping)
1818 (narrow_foreground_group, widen_foreground_group): New functions.
1819 (init_sys_modes): Narrow foreground group.
1820 (reset_sys_modes): Widen foreground group.
1822 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
1824 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
1826 2012-10-31 Martin Rudalics <rudalics@gmx.at>
1828 * minibuf.c (read_minibuf): Restore current buffer since
1829 choose_minibuf_frame calling Fset_frame_selected_window may
1830 change it (Bug#12766).
1832 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
1834 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
1836 2012-10-30 Kenichi Handa <handa@gnu.org>
1838 * font.c (Ffont_at): If WINDOW is specified and it is not
1839 displaying the current buffer, signal an error.
1841 2012-10-29 Daniel Colascione <dancol@dancol.org>
1843 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
1844 In preparation for fixing bug#12739, move these functions from
1847 * coding.h, coding.c: ... to here, and compile them only when
1848 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
1849 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
1851 2012-10-28 Eli Zaretskii <eliz@gnu.org>
1853 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
1854 (timer_loop, getitimer, setitimer): Use it instead of
1855 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
1857 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
1860 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
1862 * nsterm.m (NO_APPDEFINED_DATA): New define.
1863 (last_appdefined_event_data): New variable
1864 (last_appdefined_event): Remove.
1865 (ns_select): Initialize t from last_appdefined_event_data instead
1866 of [last_appdefined_event data1].
1867 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,

1874 2012-10-27 Eli Zaretskii <eliz@gnu.org>
1876 Avoid overflow in w32 implementation of interval timers.
1877 When possible, for ITIMER_PROF count only times the main thread
1879 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
1880 'volatile ULONGLONG' types. All the other data which was
1881 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
1882 (GetThreadTimes_Proc): New typedef.
1883 (w32_get_timer_time): New function, returns a suitable time value
1885 (timer_loop): Enter critical section when accessing ULONGLONG
1886 values of the itimer_data struct, as these accesses are no longer
1887 atomic. Call 'w32_get_timer_time' instead of 'clock'.
1888 Remove unused variable.
1889 (init_timers): Initialize s_pfn_Get_Thread_Times.
1890 (start_timer_thread): Don't assign itimer->caller_thread here.

1897 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
1898 mouse movement events if the menu bar is active. This avoids
1899 producing a busy "hour-glass" cursor by Windows if the mouse
1900 pointer is positioned over a tooltip shown for some menu item.
1902 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
1904 Don't assume process IDs fit in int.
1905 * emacs.c (shut_down_emacs) [!DOS_NT]:
1906 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
1907 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
1908 Use pid_t, not int, to store process IDs, as 'int'
1909 is not wide enough on a few platforms (e.g., AIX and IRIX).
1911 2012-10-23 Kenichi Handa <handa@gnu.org>
1913 The following change is to make face-font-rescale-alist work
1914 correctly for non-ASCII fonts.

1934 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
1936 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
1938 Port to OpenBSD 5.1.
1939 * frame.c (Fmouse_position, Fmouse_pixel_position):
1940 * xdisp.c (produce_stretch_glyph):
1941 Declare local vars only when they're needed.
1942 This is clearer and avoids a warning on OpenBSD about unused vars.

1944 This is safer, and avoids OpenBSD warnings about unused vars.
1945 * keyboard.c (record_menu_key): Remove unnecessary decl.
1946 (poll_timer): Define only if POLL_FOR_INPUT is defined.
1947 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
1948 as our definition clashes with OpenBSD's.
1949 * xfaces.c (load_face_colors, check_lface_attrs)
1950 (get_lface_attributes_no_remap, get_lface_attributes)
1951 (lface_fully_specified_p, x_supports_face_attributes_p)
1952 (tty_supports_face_attributes_p, face_fontset, realize_face)
1953 (realize_x_face, realize_tty_face):
1954 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
1955 merely Lisp_Object *. This is more informative and avoids
1956 a warning on OpenBSD about accessing beyond an object's size.
1958 2012-10-20 Chong Yidong <cyd@gnu.org>
1960 * lread.c (Fload): Doc fix (Bug#12592).

1986 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
1987 (staticpro): If we run out of staticpro slots, die with an
1988 informative error instead of just calling emacs_abort.
1990 2012-10-18 Martin Rudalics <rudalics@gmx.at>
1992 Fix two flaws reported by Dmitry Antipov.

2250 the same pointer-to-int (now pointer-to-boolean) &input_pending,

2303 2012-10-08 Daniel Colascione <dancol@dancol.org>
2305 * xdisp.c (start_hourglass): Call w32_note_current_window when

2307 build that caused Emacs to display the hourglass cursor forever.
2309 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
2310 which is broken under remote desktop, calculate the number of

2349 2012-10-08 Daniel Colascione <dancol@dancol.org>
2351 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
2352 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
2353 accidental message numbering hole. Change other messages to
2356 * w32select.h (HAVE_W32SELECT): Remove.
2358 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
2359 w32common.h instead of w32heap.h.
2361 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
2362 (get_allocation_unit, get_processor_type, get_w32_major_version)
2363 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
2364 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
2365 (OS_NT, os_subtype, cache_system_info): Move declarations to
2368 * w32heap.c: Include w32common.h.
2369 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
2370 (w32_minor_version, w32_build_number, w32_subtype):
2371 Remove duplicate definitions.
2373 * w32fns.c: Include w32common.h; include w32heap.h only in
2376 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
2377 Use `report_file_error' instead of `error' in order to better
2378 inform users of what went wrong. Increase NTGUI_UNICODE file
2379 dialog box file name length to 32k, the maximum allowed by the NT
2382 * w32common.h: New file.
2383 (ROUND_UP, ROUND_DOWN, get_page_size)
2384 (get_allocation_unit, get_processor_type, get_w32_major_version)
2385 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
2386 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
2387 (OS_NT, os_subtype, cache_system_info): Move here.
2389 * unexw32.c, unexcw.c: Include w32common.h.
2391 * emacs.c (main): Use (defined (WINDOWSNT) || defined
2392 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
2393 to call syms_of_w32select.
2395 * cygw32.h: Remove obsolete EXFUN declarations.
2397 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
2399 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
2400 of w32inevt.o from SOME_MACHINE_OBJECTS.
2402 2012-10-08 Daniel Colascione <dancol@dancol.org>
2404 * image.c: Permanent fix for JPEG compilation issue --- limit
2405 jpeglib `boolean' redefinition to Cygwin builds.
2407 2012-10-08 Eli Zaretskii <eliz@gnu.org>
2409 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
2411 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
2414 2012-10-08 Daniel Colascione <dancol@dancol.org>
2416 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
2417 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
2418 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
2419 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
2420 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
2421 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
2422 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
2423 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
2424 now a supported configuration.
2426 * Makefile.in: consolidate image variables into LIBIMAGE; add
2427 W32_OBJ and W32_LIBS. Compile new files.
2430 (_DebPrint) declare tracing facility for W32 debugging. We need
2431 to unify tracing later.
2433 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
2434 unconditional use of W32 Unicode functions. Cygwin runs only on
2435 100% Unicode operating systems.
2437 * cygw32.c: New file. Define Cygwin-specific facilities.
2438 (Fcygwin_convert_path_to_windows)
2439 (Fcygwin_convert_path_from_windows): New user functions for
2440 accessing Cygwin path-munging routines.
2442 * cygw32.h: New file.
2443 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
2444 UTF-16LE strings temporarily inside non-Lisp-visible string
2447 (w32_strerror): Just what it says on the tin.
2449 * emacs.c: Make the NS fork-then-exec code for daemon-launching
2450 also run for Cygwin; both systems have the same problem with using
2451 GUI facilities in a forked child. Also call syms_of_cygw32,
2452 syms_of_w32select in correct places.
2454 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
2455 needs fork-then-exec for daemon launching.
2457 * font.h: Include frame.h.
2459 * image.c: Use the image library cache machinery only when we're
2460 compiling for native WINDOWSNT; Cygwin can use shared libraries
2461 like any other Unixlike system.
2463 * keyboard.c: Clarify a comment regarding the input loop.
2465 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
2466 functions directly instead of trying to detect at runtime that our
2467 host operating system supports them. We make this change for two
2468 reasons: Cygwin lacks support for the multibyte character
2469 conversion functions used by the legacy menu code, and Cygwin
2470 never needs to rely on non-Unicode APIs.
2472 * unexw32.c (hinst): Declare extern.
2474 * w32.c: Change header order;
2475 (w32_strerror): Move to w32fns.c because we need it for
2476 non-WINDOWSNT builds.
2478 * w32.h: Add #error macro to make sure we don't include w32.h for
2479 Cygwin builds. Remove w32select declarations.
2481 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
2482 w32fns.c. w32console.c is WINDOWSNT-only.
2484 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
2485 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
2487 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
2488 (w32_major_version, w32_minor_version, w32_build_number)
2489 (os_subtype, sound_type): Define here
2490 (w32_defined_color): Make color parameter const for consistency
2491 with other _defined_color functions.
2492 (w32_createwindow): Unconditionally call w32_init_class instead of
2493 doing so only when hprevinst is non-NULL. Plumbing hprevinst
2494 through the code is complex and unnecessary because class
2495 registration is practically free.
2496 (w32_name_of_message): New EMACSDEBUG-only function.
2497 (Fset_message_beep): Move here
2498 (Fx_open_connection): Require that the display name for Windows be
2499 "w32" for consistency, emacsclient disambiguation, and maybe, one
2500 day, multi-window-system support.
2501 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
2502 Cygwin files for W32 GUI facilities, since these clearly don't
2503 expect Cygwin names.
2504 (_DebPrint): Define.
2505 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
2506 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
2507 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
2508 (w32_last_error): Remove.
2510 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
2512 * w32heap.c (syspage_mask): Declare here.
2513 (cache_system_info): Remove.
2515 * w32inevt.c (faked_key): Define globally, not statically.
2516 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
2517 (w32_console_toggle_lock_key): Move to w32fns.c.
2519 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
2521 * w32proc.c (_DebPrint): Move to w32fns.c.
2522 * w32select.c: Include string.h, stdio.h for Cygwin.
2523 * w32select.h: New File.
2525 * w32term.c: Include io.h for non-CYGWIN builds; needed for
2527 (w32_message_fd): New variable. Under Cygwin, holds the file
2528 descriptor the system used to tell us about pending thread
2531 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
2532 that prevented compilation under non-WINDOWSNT systems.
2534 (w32_initialize): Open /dev/windows and assign it to
2535 w32_message_fd. Provide w32 feature.
2537 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
2538 (WM_EMACS_INPUT_READY): add.
2539 (prepend_msg, w32_message_fd): Declare globally.
2542 (keyboard_handle): Use only when WINDOWSNT.
2543 (notify_msg_ready): New function. Posts a message to the main
2544 thread's message queue under CYGWIN, which wakes up the main
2545 thread from select(2) by making the /dev/windows file descriptor
2546 ready. Under WINDOWSNT, it sets an event the same way the old
2549 (post, prepend_msg): Actually call notify_msg_ready instead of
2550 setting the input event directly.
2552 2012-10-07 Eli Zaretskii <eliz@gnu.org>
2554 * ralloc.c (relinquish): If a heap is ready to be relinquished,
2555 but it still has blocs in it, don't return it to the system,
2556 instead of aborting. (Bug#12402)
2558 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
2560 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
2562 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
2563 MAC_OS_X_VERSION_10_6.
2564 (syms_of_nsterm): Remove comment about Panther and above for
2566 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
2567 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
2568 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
2570 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
2571 MAC_OS_X_VERSION_10_4.
2573 * nsmenu.m (fillWithWidgetValue:): Remove code for <
2574 MAC_OS_X_VERSION_10_2.
2576 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
2578 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
2579 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
2581 * nsterm.m (ns_in_resize): Remove (Bug#12479).
2582 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
2583 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
2584 Remove ns_in_resize check.
2585 (ns_clear_frame_area): Remove resize handle code.
2587 * nsfns.m (ns_in_resize): Remove.
2588 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
2589 Remove ns_in_resize check.
2591 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
2593 Improve sys_siglist detection.
2594 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
2595 defined as a macro, as is done in Solaris.
2596 (sys_siglist_entries): New macro.
2597 (save_strsignal): Use it.
2598 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
2599 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
2601 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
2603 * nsfns.m (Fx_create_frame): Call x_default_parameter with
2604 fullscreen/Fullscreen.
2606 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
2607 tobar_height is new.
2609 * nsterm.m (x_make_frame_visible): Check for fullscreen.
2610 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
2611 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
2612 (windowDidResize:): Check for correct window if old style fullscreen.
2613 Capitalize word in comment. Remove incorrect comment.
2614 (initFrameFromEmacs:): tbar_height renamed tibar_height.
2615 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
2616 error in drawing background.
2617 (toggleFullScreen:): Remove comment. Rearrange calls.
2618 Set toolbar values to zero, save old height in tobar_height.
2619 Restore tool bar height when leaving fullscreen.
2620 (canBecomeMainWindow): New function.
2622 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
2624 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
2626 2012-10-05 Eli Zaretskii <eliz@gnu.org>
2628 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
2630 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
2631 that time stamps of directories could also be changed.
2632 Don't request the too broad GENERIC_WRITE, only the more restrictive
2633 FILE_WRITE_ATTRIBUTES access rights.
2635 * fileio.c (Fset_file_times): Special-case ignoring errors for
2636 directories only on MSDOS, not on MS-Windows.
2638 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
2640 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
2642 2012-10-04 Eli Zaretskii <eliz@gnu.org>
2644 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
2645 see whether CreateFile failed.
2647 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
2649 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
2650 to avoid similar races.
2651 * keyboard.c (pending_signals): Now bool, not int.
2653 Port timers to OpenBSD, plus check for timer failures.
2654 OpenBSD problem reported by Han Boetes.
2655 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
2657 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
2658 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
2659 like OpenBSD, which has timer_settime but does not declare it.
2660 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
2661 whether to use itimerspec-related primitives. All uses of
2662 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
2664 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2666 * profiler.c (handle_profiler_signal): Fix a malloc race
2667 that caused Emacs to hang on Fedora 17 when profiling Lisp.
2669 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
2671 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
2673 2012-10-02 Eli Zaretskii <eliz@gnu.org>
2675 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
2676 consistent with the change in return value of 'safe_strsignal'.
2678 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2680 Prefer plain 'static' to 'static inline' (Bug#12541).
2681 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
2682 (bidi_set_sor_type, bidi_push_embedding_level)
2683 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
2684 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
2685 (bidi_cache_search, bidi_cache_ensure_space)
2686 (bidi_cache_iterator_state, bidi_cache_find)
2687 (bidi_peek_at_next_level, bidi_set_paragraph_end)
2688 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
2689 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
2690 Now 'static', not 'static inline'.
2692 Count overruns when profiling; change units to ns.
2693 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
2694 Give extra weight to samples after overruns, to attempt to count
2695 the time more accurately.
2696 (setup_cpu_timer): Change sampling interval units from ms to ns, since
2697 the underlying primitives nominally do ns.
2698 (Fprofiler_cpu_start): Document the change. Mention that
2699 the sampling intervals are only approximate.
2701 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
2703 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
2705 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
2706 case for the special 0 coding-system.
2708 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
2709 (Fmake_overlay): Remove redundant tests.
2710 (fix_start_end_in_overlays): Remove redundant recentering.
2712 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
2714 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
2715 Update dependencies.
2717 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2719 Fix a malloc race condition involving strsignal.
2720 A signal can arrive in the middle of a malloc, and Emacs's signal
2721 handler can invoke strsignal, which can invoke malloc, which is
2722 not portable. This race condition bug makes Emacs hang on GNU/Linux.
2723 Fix it by altering the signal handler so that it does not invoke
2725 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
2726 * process.c (status_message): Use const pointer, in case strsignal
2727 is #defined to safe_strsignal.
2728 * sysdep.c (sys_siglist, init_signals): Always define and
2729 initialize a substitute sys_siglist if the system does not define
2730 one, even if HAVE_STRSIGNAL.
2731 (safe_strsignal): Rename from strsignal. Always define,
2732 using sys_siglist. Return a const pointer.
2733 * syssignal.h (safe_strsignal): New decl.
2734 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
2736 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2738 * w32proc.c (timer_loop): Fix code that waits for timer
2739 expiration, to avoid high CPU usage.
2741 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
2743 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
2744 (sweep_weak_table): Remove redundant prototypes.
2746 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
2748 * emacs.c: Move the inclusion of TERM_HEADER after including
2749 windows.h on WINDOWSNT. This avoids compilation problems with
2752 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2754 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
2755 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
2756 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
2757 as the previous version used 'void *'.
2759 * ralloc.c (ROUNDUP): Fix last change.
2760 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
2763 * w32proc.c <disable_itimers>: New static flag.
2764 (init_timers): Initialize it to zero, after creating the critical
2765 sections used by the timer threads.
2766 (term_timers): Set to 1 before deleting the critical sections.
2767 (getitimer, setitimer): If disable_itimers is non-zero, return an
2768 error indication without doing anything. Reported by Fabrice
2769 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
2770 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
2772 [!HAVE_SETITIMER]: Behave as the previous version that didn't
2775 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
2776 term_ntproc after all the other bookkeeping, to get timers working
2777 as long as possible.
2779 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2781 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
2782 Suggested by Juri Linkov in
2783 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
2785 Prefer plain 'static' to 'static inline' (Bug#12541).
2786 With static functions, modern compilers inline pretty well by
2787 themselves; advice from programmers often hurts as much as it helps.
2788 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
2789 this change shrinks the text size of the Emacs executable by 1.1%
2790 without affecting CPU significantly in my benchmark.
2791 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)
2792 (live_float_p, live_misc_p, live_vector_p, live_buffer_p)
2793 (mark_maybe_object, mark_maybe_pointer, bounded_number):
2794 * buffer.c (bset_abbrev_mode, bset_abbrev_table)
2795 (bset_auto_fill_function, bset_auto_save_file_format)
2796 (bset_auto_save_file_name, bset_backed_up, bset_begv_marker)

3275 now return bool, not int. All uses changed.
3276 * image.c: Omit unnecessary static decls.
3277 (x_create_bitmap_mask, x_build_heuristic_mask):
3278 Return void, not int, since callers don't care about the return value.

3313 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3315 Move pid_t related decls out of lisp.h.
3316 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
3317 (interruptible_wait_for_termination):
3318 Move these decls from lisp.h to syswait.h, since they use pid_t.
3319 Needed on FreeBSD; see Herbert J. Skuhra in
3320 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
3321 * callproc.c: Include syswait.h.

3341 Use bool for boolean.
3342 * gtkutil.c (xg_update_frame_menubar):

3367 2012-09-23 Eli Zaretskii <eliz@gnu.org>
3369 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
3370 fatal_error_backtrace.
3372 * w32proc.c (sys_kill): Undo last change: don't do anything when
3373 invoked to deliver SIGABRT to our own process. This is now
3374 handled by emacs_raise.
3376 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
3378 * w32term.c (w32_read_socket): Remove leftover reference to
3379 interrupt_input_pending.
3381 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3383 Do not use SA_NODEFER.
3384 Problem reported by Dani Moncayo in
3385 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
3387 * sysdep.c (emacs_abort): Do not reset signal handler.
3388 * emacs.c (terminate_due_to_signal): Reset signal handler here.
3389 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
3390 wanted even on POSIXish hosts, and it doesn't work on Windows.
3392 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3394 * xterm.c (x_term_init): Call fixup_locale before and after calling
3395 gtk_init (Bug#12392).
3397 2012-09-23 Chong Yidong <cyd@gnu.org>
3399 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
3400 Vdynamic_library_alist.
3402 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
3403 (Fgnutls_available_p): Caller changed.
3405 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
3406 (Flibxml_parse_xml_region): Likewise.
3408 * dispextern.h (struct image_type): Remove arg from init function.
3410 * image.c (Finit_image_library, lookup_image_type)
3411 (define_image_type): Remove now-unneeded second arg.
3412 (init_xpm_functions, init_png_functions, init_jpeg_functions)
3413 (init_tiff_functions, init_gif_functions, init_svg_functions):
3414 Arglist and w32_delayed_load calling convention changed.
3415 (gs_type): Remove init_gs_functions; there is no such function.
3416 (valid_image_p, make_image): Fix caller to lookup_image_type.
3418 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3420 Simplify and avoid signal-handling races (Bug#12471).
3422 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
3423 Avoid recursive loop if there's a fatal error in the function itself.
3424 * atimer.c (pending_atimers):
3425 * blockinput.h: Don't include "atimer.h"; no longer needed.
3426 (interrupt_input_pending): Remove. All uses removed.
3427 pending_signals now counts both atimers and ordinary interrupts.
3428 This is less racy than having three separate pending-signal flags.
3429 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
3431 Rename from their upper-case counterparts BLOCK_INPUT,
3432 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
3433 INPUT_BLOCKED_P, and turn into functions. All uses changed.
3434 This makes it easier to access volatile variables more accurately.
3435 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
3436 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
3437 that's more reliable if the code is buggy and sets
3438 interrupt_input_blocked to a negative value. All uses changed.
3439 * atimer.c (deliver_alarm_signal):
3440 Remove. No need to deliver this to the parent; any thread can
3441 handle this signal now. All uses replaced by underlying handler.
3442 * atimer.c (turn_on_atimers):
3443 * dispnew.c (handle_window_change_signal):
3444 * emacs.c (handle_danger_signal):
3445 * keyboard.c (kbd_buffer_get_event):
3446 Don't reestablish signal handler; not needed with sigaction.
3447 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
3449 Rework to avoid unnecessary accesses to volatile variables.
3450 (UNBLOCK_INPUT_TO): Now a function.
3451 (totally_unblock_input, unblock_input): New decls.
3452 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
3453 (init_data): Remove. Necessary stuff now done in init_signal.
3454 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
3455 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
3456 (fatal_error_code): Remove; no longer needed.
3457 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
3458 it doesn't always backtrace. All uses changed. No need to reset
3459 signal to default, since sigaction and/or die does that for us now.
3460 Use emacs_raise (FOO), not kill (getpid (), FOO).
3461 (main): Check more-accurately whether we're dumping.
3462 Move fatal-error setup to sysdep.c
3463 * floatfns.c: Do not include "syssignal.h"; no longer needed.
3464 * gtkutil.c (xg_get_file_name, xg_get_font):
3465 Remove no-longer-needed signal-mask manipulation.
3466 * keyboard.c, process.c (POLL_FOR_INPUT):
3467 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
3468 * keyboard.c (read_avail_input): Remove.
3469 All uses replaced by gobble_input.
3470 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
3471 (kbd_buffer_store_event_hold, gobble_input):
3472 (record_asynch_buffer_change) [USABLE_SIGIO]:
3473 (store_user_signal_events):
3474 No need to mess with signal mask.
3475 (gobble_input): If blocking input and there are terminals, simply
3476 set pending_signals to 1 and return. All hooks changed to not
3477 worry about whether input is blocked.
3478 (process_pending_signals): Clear pending_signals before processing
3479 them, in case a signal comes in while we're processing.
3480 By convention callers now test pending_signals before calling us.
3481 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
3482 New functions, to support changes to blockinput.h.
3483 (handle_input_available_signal): Now extern.
3484 (reinvoke_input_signal): Remove. All uses replaced by
3486 (quit_count): Now volatile, since a signal handler uses it.
3487 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
3488 All callers changed. Block SIGINT only if not already blocked.
3489 Clear sigmask reliably, even if Fsignal returns, which it can.
3490 Omit unnecessary accesses to volatile var.
3491 (quit_throw_to_read_char): No need to restore sigmask.
3492 * keyboard.c (gobble_input, handle_user_signal):
3493 * process.c (wait_reading_process_output):
3494 Call signal-handling code rather than killing ourselves.
3495 * lisp.h: Include <float.h>, for...
3496 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
3497 (pending_signals): Now volatile.
3498 (syms_of_data): Now const if IEEE floating point.
3499 (handle_input_available_signal) [USABLE_SIGIO]:
3500 (terminate_due_to_signal, record_child_status_change): New decls.
3501 * process.c (create_process): Avoid disaster if memory is exhausted
3502 while we're processing a vfork, by tightening the critical section
3504 (send_process_frame, process_sent_to, handle_pipe_signal)
3505 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
3507 (send_process): No need for setjmp/longjmp any more, since the
3508 SIGPIPE stuff is now gone. Instead, report an error if errno
3510 (record_child_status_change): Now extern. PID and W are now args.
3511 Return void, not bool. All callers changed.
3512 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
3513 Remove. All uses removed. This bug should be fixed now in a
3515 (wait_for_termination_1): Use waitpid rather than sigsuspend,
3516 and record the child status change directly. This avoids the
3517 need to futz with the signal mask.
3518 (process_fatal_action): Move here from emacs.c.
3519 (emacs_sigaction_flags): New function, containing
3520 much of what used to be in emacs_sigaction_init.
3521 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
3522 caught by emacs, to make races less likely.
3523 (deliver_process_signal): Rename from handle_on_main_thread.
3525 (BACKTRACE_LIMIT_MAX): Now at top level.
3526 (thread_backtrace_buffer, threadback_backtrace_pointers):
3528 (deliver_thread_signal, deliver_fatal_thread_signal):
3529 New functions, for more-accurate delivery of thread-specific signals.
3530 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
3531 (deliver_arith_signal): Handle in this thread, not
3532 in the main thread, since it's triggered by this thread.
3533 (maybe_fatal_sig): New function.
3534 (init_signals): New arg DUMPING so that we can be more accurate
3535 about whether we're dumping. Caller changed.
3536 Treat thread-specific signals differently from process-general signals.
3537 Block all signals while handling fatal error; that's safer.
3538 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
3540 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
3541 Ignore SIGPIPE unless batch.
3542 (emacs_backtrace): Output backtrace for the appropriate thread,
3543 which is not necessarily the main thread.
3544 * syssignal.h: Include <stdbool.h>.
3545 (emacs_raise): New macro.
3546 * xterm.c (x_connection_signal): Remove; no longer needed
3547 now that we use sigaction.
3548 (x_connection_closed): No need to mess with sigmask now.
3549 (x_initialize): No need to reset SIGPIPE handler here, since
3550 init_signals does this for us now.
3552 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3554 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
3555 background rect may be larger (Bug#12245).
3557 2012-09-23 Chong Yidong <cyd@gnu.org>
3559 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
3561 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3563 * .gdbinit: Just stop at fatal_error_backtrace.
3564 See Stefan Monnier's request in
3565 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
3566 Remove no-longer-used query of system type.
3568 2012-09-22 Chong Yidong <cyd@gnu.org>
3570 * search.c (Freplace_match): Doc fix (Bug#12325).
3572 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
3574 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
3575 (Fline_end_position): Doc fix.
3577 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
3579 2012-09-22 Chong Yidong <cyd@gnu.org>
3581 * dispextern.h (struct image_type): Add new slot, storing a type
3582 initialization function.
3584 * image.c (define_image_type): Call the image initializer function
3585 if it is defined. Arguments and return value changed.
3586 (valid_image_p, make_image): Callers changed.
3587 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
3588 (gif_type, imagemagick_type, svg_type, gs_type):
3589 Add initialization functions.
3590 (Finit_image_library): Call lookup_image_type.
3591 (CHECK_LIB_AVAILABLE): Macro deleted.
3592 (lookup_image_type): Call define_image_type here, rather than via
3593 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
3594 (syms_of_image): Move define_image_type calls for xbm_type and
3595 pbm_type to lookup_image_type.
3597 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3599 * keyboard.c (timer_check_2): Move calculation of 'timers' and
3600 'idle_timers' from here ...
3601 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
3602 lists, to avoid infloops when the timer does something stupid,
3603 like reinvoke itself with the same or smaller time-out.
3606 2012-09-22 Martin Rudalics <rudalics@gmx.at>
3608 * window.c (Fsplit_window_internal): Handle only Qt value of
3609 Vwindow_combination_limit separately.
3610 (Qtemp_buffer_resize): New symbol.
3611 (Vwindow_combination_limit): New default value.
3614 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3616 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
3617 the new overlay string. (Bug#10159)
3619 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3621 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
3622 or that fprintf is async-signal-safe. POSIX doesn't require
3625 2012-09-22 Chong Yidong <cyd@gnu.org>
3627 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
3630 2012-09-22 Kenichi Handa <handa@gnu.org>
3632 * composite.c (composition_reseat_it): Handle the case that a
3633 grapheme cluster is not covered by a single font (Bug#12352).
3635 2012-09-21 Chong Yidong <cyd@gnu.org>
3637 * image.c (define_image_type): Avoid adding duplicate types to
3638 image_types (Bug#12463). Suggested by Jörg Walter.
3640 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3642 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
3643 (print_load_command_name): Add case LC_DATA_IN_CODE.
3644 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.

3648 * eval.c (Frun_hook_with_args_until_success)
3649 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
3651 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
3653 * fileio.c (Ffile_selinux_context): Only call freecon when
3654 lgetfilecon succeeded.
3655 (Fset_file_selinux_context): Likewise. (Bug#12444)
3657 2012-09-21 Eli Zaretskii <eliz@gnu.org>
3659 * xdisp.c (try_window_reusing_current_matrix): Under bidi
3660 reordering, locate the cursor by calling set_cursor_from_row; if
3661 that fails, clear the desired glyph matrix before returning a
3662 failure indication to the caller. Fixes leaving garbled display
3663 when fast scrolling with a down-key. (Bug#12403)
3664 (compute_stop_pos_backwards): Fix a typo that caused crashes while
3665 scrolling through multibyte text.
3667 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
3669 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
3670 calling mark_vectorlike since that's the one that marks the window.
3671 (mark_discard_killed_buffers): Mark the final cdr.
3672 * window.h (struct window): Move prev/next_buffers to the
3673 non-standard fields.
3674 * window.c (make_window): Initialize prev/next_buffers manually.
3676 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
3678 Omit unused arg EXPECTED from socket hooks.
3679 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
3680 * nsterm.m (ns_term_init):
3681 * termhooks.h (struct terminal.read_socket_hook):

3683 * w32term.c (w32_read_socket):
3684 * xterm.c (XTread_socket):
3685 Omit unused arg EXPECTED. All callers changed.
3686 (store_user_signal_events): Return void, not int, since callers no
3687 longer care about the return value. All uses changed.
3689 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
3691 * w32gui.h (XParseGeometry): Do not declare.
3693 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
3695 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
3696 Ignore 'expected'. See Eli Zaretskii in
3697 <http://bugs.gnu.org/12471#8> (last line).
3699 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
3700 (XParseGeometry): Now static. Substitute extremal values for
3701 values that are out of range.
3703 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
3705 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
3707 * nsfns.m (XParseGeometry): Remove.
3708 (Fx_create_frame): Call x_set_offset to correctly interpret
3709 top_pos in geometry.
3711 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
3712 (Fx_parse_geometry): If there is a space in string, call
3713 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
3715 2012-09-17 Eli Zaretskii <eliz@gnu.org>
3717 * search.c (scan_buffer): Use character positions in calls to
3718 region_cache_forward and region_cache_backward, not byte
3719 positions. (Bug#12196)
3721 * w32term.c (w32_read_socket): Set pending_signals to 1, like
3722 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
3724 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
3725 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
3726 emacs_blocked_malloc, now deleted.
3728 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
3730 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
3731 The workaround was for improving performance on Solaris 2.4, but
3732 is getting in the way now. Emacs will still work if someone is
3733 still running Solaris 2.4 in a museum somewhere; Sun dropped
3734 support for Solaris 2.4 in 2003.
3735 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
3736 * process.c (create_process) [HAVE_WORKING_VFORK]:
3737 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
3738 since Emacs no longer uses vfork on that platform.
3740 2012-09-17 Glenn Morris <rgm@gnu.org>
3742 * emacs.c: Use COPYRIGHT.
3744 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
3746 Remove configure's --without-sync-input option (Bug#12450).
3747 When auditing signal-handling in preparation for cleaning it up,
3748 I found that SYNC_INPUT has race conditions and would be a real
3749 pain to fix. Since it's an undocumented and deprecated
3750 configure-time option, now seems like a good time to remove it.
3751 Also see <http://bugs.gnu.org/11080#16>.
3752 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
3753 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
3754 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3755 (malloc_hysteresis):
3756 (check_depth) [XMALLOC_OVERRUN_CHECK]:
3757 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
3758 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
3759 (dont_register_blocks, bytes_used_when_reconsidered)
3760 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
3761 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
3762 [!SYSTEM_MALLOC && !SYNC_INPUT]:
3763 Remove. All uses removed.
3764 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
3765 implementation, one that depends on whether the new macro
3766 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
3768 * atimer.c (run_timers, handle_alarm_signal):
3769 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
3770 (handle_async_input, process_pending_signals)
3771 (handle_input_available_signal, init_keyboard):
3772 * nsterm.m (ns_read_socket):
3773 * process.c (wait_reading_process_output):
3774 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
3775 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
3777 * xterm.c (XTread_socket):
3779 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
3780 * eval.c (handling_signal): Remove. All uses removed.
3781 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
3782 All uses replaced with the SYNC_INPUT version.
3783 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
3785 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3788 * font.c (Ffont_shape_gstring): Remove unused local.
3790 2012-09-16 Glenn Morris <rgm@gnu.org>
3792 * Makefile.in (clean): No longer run nextstep's clean.
3794 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
3796 (ns-app): Move here from ns.mk, and simplify.
3797 (clean): Simplify nextstep entry.
3798 * ns.mk: Remove file.
3800 2012-09-17 Kenichi Handa <handa@gnu.org>
3802 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
3803 not covert the last few charactes.
3805 2012-09-16 Kenichi Handa <handa@gnu.org>
3807 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
3808 here, but just check the validity of glyphs in the glyph-string.
3810 2012-09-16 Martin Rudalics <rudalics@gmx.at>
3812 * window.c (Fwindow_parameter, Fset_window_parameter):
3813 Accept any window as argument (Bug#12452).
3815 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
3817 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
3818 to ns_term_init to avoid memory leak.
3820 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
3821 explicit retain/release.
3822 (ns_term_init): Only allow one display. Initialize outerpool and
3825 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3827 Port _setjmp fix to POSIXish hosts as well as Microsoft.
3828 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
3829 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
3830 the Microsoft problem in a different way, by altering ../nt/config.nt.
3832 2012-09-15 Eli Zaretskii <eliz@gnu.org>
3847 * w16select.c: Remove inclusion of setjmp.h, as it is now included
3848 by lisp.h. This completes removal of setjmp.h inclusion
3849 erroneously announced in the previous commit. (Bug#12446)
3851 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
3854 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
3855 not defined as a macro. The latter happens on MS-Windows.
3858 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3860 Port better to POSIX hosts lacking _setjmp (Bug#12446).
3861 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
3862 Some instances of '#include <setjmp.h>' removed, if the
3863 only reason for the instance was because "lisp.h" was included.
3864 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
3865 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
3866 and _longjmp with the new symbols. Emacs already uses _setjmp if
3867 available, so this change affects only POSIXish hosts that have
3868 sigsetjmp but not _setjmp, such as some versions of Solaris and
3869 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
3870 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
3871 (png_load_body) [HAVE_PNG]:
3872 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
3873 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
3874 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
3875 since PNG requires jmp_buf. This is the only exception to the
3876 general rule that we now use sys_setjmp and sys_longjmp.
3877 This exception is OK since this code does not change the signal
3878 mask or longjmp out of a signal handler.
3880 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
3882 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3883 Include "syssignal.h", for 'main_thread'.
3885 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
3887 Avoid out-of-range marker position (Bug#12426).
3888 * insdel.c (replace_range, replace_range_2):
3889 Adjust markers before overlays, as suggested by comments.
3890 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
3891 Remove redundant check before calling offset_intervals.
3893 2012-09-14 Martin Rudalics <rudalics@gmx.at>
3895 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
3896 current buffer (Bug#12387).
3898 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
3900 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
3902 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3904 Use a more backwards-compatible timer format (Bug#12430).
3905 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
3906 vector element, not from the 4th, since PSECS is now at the end.
3907 (Fcurrent_idle_time): Doc fix.
3909 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
3911 Function to mark objects and remove killed buffers at once.
3912 * alloc.c (discard_killed_buffers): Rename to ...
3913 (mark_discard_killed buffers) ... new name. Add marking
3914 of remaining objects. Fix comment. Adjust users.
3915 (mark_object): Do not touch frame buffer lists here.
3916 * frame.c (delete_frame): Reset frame buffer lists here.
3918 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3920 Better workaround for GNOME bug when --enable-gcc-warnings.
3921 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
3922 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
3923 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
3925 Simplify SIGIO usage (Bug#12408).
3926 The code that dealt with SIGIO was crufty and confusing, e.g., it
3927 played tricks like "#undef SIGIO" but these tricks were not used
3928 consistently. Simplify mostly by not #undeffing standard symbols,
3929 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
3930 or not as we please) rather than "defined SIGIO" (standard symbol
3931 that we probably shouldn't #undef).
3932 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
3933 Modules that need it can include it.
3934 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
3935 * dispextern.h (ignore_sigio): New decl.
3936 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
3937 unconditionally, since it's now a no-op if !USABLE_SIGIO.
3938 * emacs.c (shut_down_emacs):
3939 * keyboard.c (kbd_buffer_store_event_hold):
3940 Use ignore_sigio rather than invoking 'signal' directly.
3941 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
3943 (FIONREAD, SIGIO): Do not #undef.
3944 (tty_read_avail_input): Use #error rather than a syntax error.
3945 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
3946 for I_PIPE, used by SETUP_SLAVE_PTY.
3947 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
3948 * sysdep.c (croak): Remove; no longer needed. This bit of
3949 temporary code, with Fred N. Fish's comment that it's temporary,
3950 has been in Emacs since at least 1992!
3951 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
3952 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
3953 * syssignal.h (croak): Remove decl.
3954 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
3955 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
3956 now that we're termios-only.
3957 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
3958 * term.c (dissociate_if_controlling_tty): Use #error rather than
3961 Work around GCC and GNOME bugs when --enable-gcc-warnings.
3962 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
3963 to work around GNOME bug 683906.
3964 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
3965 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
3966 This works around GCC bug 54561.
3968 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
3970 More fixes for 'volatile' and setjmp/longjmp.
3971 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
3972 * image.c (struct png_load_context) [HAVE_PNG]: New type.
3973 (png_load_body) [HAVE_PNG]:
3974 (jpeg_load_body) [HAVE_JPEG]:
3975 New function, with most of the old parent function's body.
3976 (png_load) [HAVE_PNG]:
3977 (jpeg_load) [HAVE_JPEG]:
3978 Invoke the new function, to avoid longjmp munging our locals.
3979 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
3980 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
3981 longjmp is passed 2, as the C standard doesn't guarantee this.
3982 Instead, store the failure code into mgr->failure_code.
3984 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
3986 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
3987 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
3988 (syms_of_keyboard): Remove support for unread-command-char.
3990 2012-09-12 Eli Zaretskii <eliz@gnu.org>
3992 * w32proc.c (sys_kill): If PID is our process ID and the signal is
3993 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
3994 violation. (Bug#12426)
3996 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
3998 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
4000 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4002 * eval.c: Add `inhibit-debugger'.
4003 (Qinhibit_debugger): New symbol.
4004 (call_debugger): Bind it instead of Qdebug_on_error.
4005 (maybe_call_debugger): Test Vinhibit_debugger.
4006 (syms_of_eval): Define inhibit-debugger.
4007 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
4008 (syms_of_xdisp): Remove inhibit-debug-on-message.
4010 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4012 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
4013 If a nonvolatile local variable is written before a _longjmp to
4014 the frame containing the variable, and is read after the _longjmp,
4015 the value read is indeterminate. Some local variables of type
4016 'struct handler' and 'struct catchtag' are used in this way, so
4017 mark each of their slots as volatile if the slot can be set before
4018 _longjmp and read afterwards.
4019 * lisp.h (struct handler): var and chosen_clause are now volatile.
4020 (struct catchtag): val, next, and pdlcount are now volatile.
4022 * bidi.c (bidi_push_it, bidi_pop_it):
4023 * fns.c (copy_hash_table):
4024 * image.c (define_image_type):
4025 * keyboard.c (kbd_buffer_store_event_hold):
4026 * process.c (Fprocess_send_eof):
4027 * xfaces.c (x_create_gc) [HAVE_NS]:
4028 * xgselect.c (xg_select):
4029 Prefer assignment to memcpy when either will do.
4031 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
4032 Use pointer-to-a-pointer to simplify and avoid a NILP check each
4033 time an item is removed. No need to mark this function 'inline';
4034 the compiler knows better than we do.
4036 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
4038 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
4039 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
4040 to change_frame_size (Bug#12388).
4041 (windowDidResize:): Pass YES to updateFrameSize.
4043 * nsterm.h: Add delay parameter to updateFrameSize.
4045 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4047 Discard killed buffers from deleted window and frame objects.
4048 This reduces an amount of references to killed buffers and
4049 helps GC to reclaim them faster.
4050 * alloc.c (discard_killed_buffers): New function.
4051 (mark_object): Use it for deleted windows and frames.
4052 (mark_object): If symbol's value is set up for a killed buffer
4053 or deleted frame, restore its global binding.
4054 * data.c (swap_in_global_binding): Add GC notice.
4055 (swap_in_symval_forwarding): Use convenient set_blv_where.
4056 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
4057 * window.h: ... to here.
4059 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4061 Convenient macro to check whether the buffer is live.
4062 * buffer.h (BUFFER_LIVE_P): New macro.
4063 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
4064 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
4066 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4068 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
4069 composition cases (Bug#12364).
4071 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
4072 overhang of succeeding glyphs overlapping box cursor.
4074 * w32term.c (x_draw_glyph_string): Likewise.
4076 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4078 Simplify, document, and port floating-point (Bug#12381).
4079 The porting part of this patch fixes bugs on non-IEEE platforms
4080 with frexp, ldexp, logb.
4081 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
4083 * floatfns.c: Simplify discussion of functions that Emacs doesn't
4084 support, by removing commented-out code and briefly listing the
4085 C89 functions excluded. The commented-out stuff was confusing
4086 maintenance, e.g., we thought we needed cbrt but it was commented out.
4087 (logb): Remove decl; no longer needed.
4088 (isfinite): New macro, if not already supplied.
4089 (isnan): Don't replace any existing macro.
4090 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
4091 are present on all C89 platforms.
4092 (Ffrexp): Do not special-case zero, as frexp does the right thing
4094 (Flogb): Do not use logb, as it doesn't have the desired meaning
4095 on hosts that use non-base-2 floating point. Instead, stick with
4096 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
4097 frexp, to avoid getting an unspecified result.
4099 * xdisp.c (Qinhibit_debug_on_message): Now static.
4101 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
4103 * nsterm.m (ns_update_begin): Set clip path to whole view by using
4104 NSBezierPath (Bug#12131).
4106 2012-09-10 Chong Yidong <cyd@gnu.org>
4108 * fns.c (Fdelq, Fdelete): Doc fix.
4110 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
4112 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
4113 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
4115 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
4117 * lisp.h (make_lisp_ptr): New macro to replace XSET.
4118 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
4121 2012-09-09 Eli Zaretskii <eliz@gnu.org>
4123 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
4124 left fringe if the window has a left margin. This avoids leaving
4125 traces of the cursor because its leftmost pixel is not drawn over.
4127 * dispnew.c (update_window_line): When the left margin area of a
4128 screen line is updated, set the redraw_fringe_bitmaps_p flag of
4129 that screen line. (Bug#12277)
4131 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
4133 Assume C89 or later for math functions (Bug#12381).
4134 This simplifies the code, and makes it a bit smaller and faster,
4135 and (most important) makes it easier to clean up signal handling
4136 since we can stop worring about floating-point exceptions in
4137 library code. That was a problem before C89, but the problem
4138 went away many years ago on all practical Emacs targets.
4139 * data.c, image.c, lread.c, print.c:
4140 Don't include <math.h>; no longer needed.
4141 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
4142 might be autoconfigured, as that never happens.
4144 * doprnt.c (DBL_MAX_10_EXP):
4145 * print.c (DBL_DIG):
4146 Remove. C89 or later always defines these.
4147 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
4148 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
4149 (arith_error, domain_error, domain_error2):
4150 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
4151 no longer needed -- we simply return what C returns. All uses removed.
4152 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
4154 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
4155 Remove. All uses expanded, as these macros are no longer used
4156 more than once and are now more trouble than they're worth.
4157 (Ftan): Use tan, not sin / cos.
4158 (Flogb): Assume C89 frexp.
4159 (fmod_float): Assume C89 fmod.
4160 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
4161 (init_floatfns): Remove. All uses removed.
4163 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4165 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
4166 compositeToPoint for OSX < 10.6 (Bug#12390).
4168 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
4170 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
4171 This produces more-accurate results.
4173 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4175 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
4176 changes (Bug#12088).
4178 2012-09-08 Chong Yidong <cyd@gnu.org>
4180 * syntax.c (Fstring_to_syntax): Doc fix.
4182 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4184 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
4185 in the internal border.
4186 (x_set_window_size): Remove static variables and their usage.
4187 (ns_redraw_scroll_bars): Fix NSTRACE arg.
4188 (ns_after_update_window_line, ns_draw_fringe_bitmap):
4189 Remove fringe/internal border adjustment (Bug#11052).
4190 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
4191 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
4192 (ns_fix_rect_ibw): Remove.
4193 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
4194 (ns_dumpglyphs_box_or_relief): Ditto.
4195 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
4197 (ns_dumpglyphs_image): Ditto.
4198 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
4200 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
4201 their usage. Add fringe_extended_p and its use as in other terms.
4202 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
4203 scroll bar was removed.
4204 (updateFrameSize): New function.
4205 (windowDidResize): Move code to updateFrameSize and call it.
4207 * nsterm.h (EmacsView): Add updateFrameSize.
4209 2012-09-07 Chong Yidong <cyd@gnu.org>
4211 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
4213 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
4215 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4217 More signal-handler cleanup (Bug#12327).
4218 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
4219 Problem introduced when merging patches. Noted by Eli Zaretskii in
4220 <http://bugs.gnu.org/12327#67>.
4221 * floatfns.c: Comment fix.
4222 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
4223 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
4224 and anyway the declaration is harmless even if SIGDANGER is not defined.
4225 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
4226 defined BROKEN_FIONREAD). systty.h formerly did this, but other
4227 source files not surprisingly expected syssignal.h to define, or
4228 not define, SIGIO, and it's cleaner to do it that way, for consistency.
4229 Include <sys/ioctl.h>, for FIONREAD.
4230 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
4231 This eliminates a problem whereby other files mysteriously had
4232 to include "syssignal.h" before including "systty.h" if they
4233 wanted to use "#ifdef SIGIO".
4235 2012-09-07 Eli Zaretskii <eliz@gnu.org>
4237 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
4239 * w32.c (sigemptyset): Empty the set.
4240 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
4242 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
4244 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
4246 * alloc.c (mark_buffer): Revert unsafe marking optimization.
4247 (mark_object): Likewise for frame objects.
4249 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4251 * syssignal.h (handle_on_main_thread): Always declare,
4252 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
4253 This ports to platforms without HAVE_PTHREAD.
4255 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4257 Signal-handler cleanup (Bug#12327).
4258 Emacs's signal handlers were written in the old 4.2BSD style with
4259 sigblock and sigmask and so forth, and this led to some
4260 inefficiencies and confusion. Rewrite these to use
4261 pthread_sigmask etc. without copying signal sets around. Also,
4262 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
4263 'signal', and instead use functions that do not attempt to take
4264 over the system name space. This patch causes Emacs's text
4265 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
4266 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
4267 Do not include <signal.h> or "syssignal.h", as these
4268 modules do not use signals.
4269 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
4270 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
4271 Do not include <signal.h>, as "syssignal.h" does that for us now.
4272 * atimer.c (sigmask_atimers): New function.
4273 (block_atimers, unblock_atimers): New functions,
4274 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
4276 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
4277 no longer needed here.
4278 * emacs.c (main): Inspect existing signal handler with sigaction,
4279 so that there's no need to block and unblock SIGHUP.
4280 * sysdep.c (struct save_signal): New member 'action', replacing
4281 old member 'handler'.
4282 (save_signal_handlers, restore_signal_handlers):
4283 Use sigaction instead of 'signal' to save and restore.
4284 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
4285 New function. All users of 'signal' modified to use set_sighandler
4286 if they're writeonly, and to use sys_signal if they're read+write.
4287 (emacs_sigaction_init, forwarded_signal): New functions.
4288 (sys_signal): Remove. All uses replaced by calls to sigaction
4289 and emacs_sigaction_init, or by direct calls to 'signal'.
4290 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
4291 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
4292 all uses replaced by pthread_sigmask etc. calls.
4293 * syssignal.h: Include <signal.h>.
4294 (emacs_sigaction_init, forwarded_signal): New decls.
4295 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
4296 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
4297 (sigmask, sys_sigmask): Remove; no longer needed.
4298 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
4299 (sigblock, sigunblock, sigfree):
4300 (sigsetmask) [!defined sigsetmask]:
4301 Remove. All uses replaced by pthread_sigmask.
4302 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
4303 no longer need to be replaced, and its typical old uses
4304 are now done via emacs_sigaction_init and sigaction.
4305 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
4306 (sys_sigdel): Remove; unused.
4307 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
4309 2012-09-06 Eli Zaretskii <eliz@gnu.org>
4311 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
4312 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
4314 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4316 Explicitly mark buffer_defaults and buffer_local_symbols.
4317 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
4318 mark_local_symbols here.
4319 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
4320 since special buffers aren't marked here any more.
4321 (allocate_buffer): Chain new buffer with all_buffers here...
4322 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
4324 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
4325 (syms_of_buffer): Remove staticpro of the above.
4326 (init_buffer_once): Set names for buffer_defaults and
4327 buffer_local_symbols.
4329 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4331 Use bool for booleans in font-related modules.
4332 * font.c (font_intern_prop, font_style_to_value)
4333 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
4334 (generate_otf_features, font_check_otf_features, font_check_otf)
4335 (font_match_p, font_list_entities, font_at):
4336 * fontset.c (fontset_id_valid_p, reorder_font_vector
4337 (fontset_find_font, Fset_fontset_font)
4338 (face_suitable_for_char_p) [0]:
4339 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
4340 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
4341 (m17n_flt_initialized, ftfont_shape_by_flt):
4342 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
4343 * nsfont.m (nsfont_draw):
4344 * w32font.c (w32font_draw):
4345 * w32term.c (x_draw_glyphless_glyph_string_foreground):
4346 Use bool for booleans.
4347 * font.h: Adjust to above API changes.
4348 (struct font, struct font_driver, struct font_driver_list):
4349 Use bool for booleans.
4350 (struct font): Remove useless member encoding_type.
4352 * fontset.c, xftfont.c: Omit unnecessary static decls.
4354 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4356 * alloc.c (mark_object): Revert window marking code
4357 since it's unsafe for the Fset_window_configuration.
4359 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4361 Fix race conditions with signal handlers and errno (Bug#12327).
4362 Be more systematic about preserving errno whenever a signal
4363 handler returns, even if it's not in the main thread. Do this by
4364 renaming signal handlers to distinguish between signal delivery
4365 and signal handling. All uses changed.
4366 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
4367 * data.c (deliver_arith_signal): Rename from arith_error.
4368 * dispnew.c (deliver_window_change_signal): Rename from
4369 window_change_signal.
4370 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
4371 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
4372 * keyboard.c (deliver_input_available_signal): Rename from
4373 input_available_signal.
4374 (deliver_user_signal): Rename from handle_user_signal.
4375 (deliver_interrupt_signal): Rename from interrupt_signal.
4376 * process.c (deliver_pipe_signal): Rename from send_process_trap.
4377 (deliver_child_signal): Rename from sigchld_handler.
4378 * atimer.c (handle_alarm_signal):
4379 * data.c (handle_arith_signal):
4380 * dispnew.c (handle_window_change_signal):
4381 * emacs.c (handle_fatal_signal, handle_danger_signal):
4382 * keyboard.c (handle_input_available_signal):
4383 * keyboard.c (handle_user_signal, handle_interrupt_signal):
4384 * process.c (handle_pipe_signal, handle_child_signal):
4385 New functions, with the actual signal-handling code taken from the
4386 original respective signal handlers, sans the sporadic attempts to
4387 preserve errno, since that's now done by handle_on_main_thread.
4388 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
4389 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
4390 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4392 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4393 Move initialization of main_thread to sysdep.c's init_signals.
4394 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
4395 our usage, and simplifies the mainline code.
4396 (record_child_status_change): New static function, as a helper
4397 for handle_child_signal, and with most of the old child handler's
4399 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
4400 (handle_child_signal): Use the above.
4401 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4402 Moved here from emacs.c.
4403 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
4404 code moved here from emacs.c's main function.
4405 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
4406 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
4407 This lets callers save and restore errno properly.
4409 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4411 Remove redundant or unused things here and there.
4412 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
4413 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
4414 * editfns.c (Fcompare_buffer_substrings): Likewise.
4415 * frame.h (struct terminal, struct font_driver_list):
4416 Remove redundant declarations.
4417 * window.h (Qleft, Qright): Likewise.
4419 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4421 Do not mark objects from deleted buffers, windows and frames.
4422 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
4423 (mark_object): Likewise for windows and frames.
4425 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4427 * alloc.c (valid_lisp_object_p): Treat killed buffers,
4428 buffer_defaults and buffer_local_symbols as valid objects.
4429 Return special value to denote them.
4431 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4433 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
4434 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
4435 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
4436 (file_name_absolute_p, Fsubstitute_in_file_name):
4437 (check_executable, check_writable, Ffile_accessible_directory_p)
4438 (Fset_file_selinux_context, Fdefault_file_modes)
4439 (Finsert_file_contents, choose_write_coding_system)
4440 (Fwrite_region, build_annotations, a_write, e_write)
4442 * filelock.c (boot_time_initialized, get_boot_time)
4443 (get_boot_time_1, lock_file_1, within_one_second):
4444 * floatfns.c (in_float):
4445 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
4446 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
4447 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
4448 * lisp.h (struct Lisp_Hash_Table.cmpfn):
4449 * window.c (compare_window_configurations):
4450 Use bool for booleans.
4451 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
4452 (Fdefault_file_modes): Now mode_t, not int, for modes.
4453 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
4454 (internal_delete_file): Now returns void, not a (boolean) int,
4455 since nobody was looking at the return value.
4456 * lisp.h, window.h: Adjust to above API changes.
4458 * xdisp.c (set_message): Simplify and reindent last change.
4460 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
4462 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
4464 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
4466 * eval.c (call_debugger): Make the function non-static so that we
4467 can call it from set_message.
4469 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
4470 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
4472 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4474 Give more-useful info on a fatal error (Bug#12328).
4475 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
4476 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
4477 of doing the work ourselves.
4478 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
4479 do most of the work.
4480 (fatal_error_backtrace): New function, taken from the guts
4481 of the old fatal_error_signal, but with a new option to output
4483 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
4484 info about the signal than just its number.
4485 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
4486 * sysdep.c: Include <execinfo.h>
4487 (emacs_backtrace): New function, taken partly from the previous
4488 code of the 'die' function.
4489 (emacs_abort): Call fatal_error_backtrace rather than abort.
4491 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
4493 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
4494 eager (load-time) macro-expansion.
4495 * lisp.mk (lisp): Add macroexp.
4497 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4499 Simplify redefinition of 'abort' (Bug#12316).
4500 Do not try to redefine the 'abort' function. Instead, redo
4501 the code so that it calls 'emacs_abort' rather than 'abort'.
4502 This removes the need for the NO_ABORT configure-time macro
4503 and makes it easier to change the abort code to do a backtrace.
4504 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
4505 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
4506 Remove; sysdep.c's emacs_abort now takes its place.
4507 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
4508 'abort' changed to use 'emacs_abort'.
4509 * msdos.c (dos_abort) [defined abort]: Remove; not used.
4510 (abort) [!defined abort]: Rename to ...
4511 (emacs_abort): ... new name.
4512 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
4513 the place of the old 'abort' in emacs.c.
4514 * w32.c, w32fns.c (abort): Do not #undef.
4515 * w32.c (emacs_abort): Rename from w32_abort.
4517 2012-09-04 Eli Zaretskii <eliz@gnu.org>
4519 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
4520 offsets[j].dv, since the y axis of the screen coordinates points
4521 down, while the y axis of the font definition coordinates points
4522 up. This fixes display of Arabic diacritics such as KASRA and
4523 KASRATAN. (Bug#11860)
4525 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4527 Be more systematic about _setjmp vs setjmp.
4528 * alloc.c (test_setjmp, mark_stack):
4529 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
4530 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
4531 (png_load, my_error_exit, jpeg_load):
4532 * process.c (send_process_trap, send_process):
4533 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
4534 The underscored versions are up to 30x faster on some hosts.
4535 Formerly, the code used setjmp+longjmp sometimes and
4536 _setjmp+_longjmp at other times, with no particular reason to
4537 prefer setjmp+longjmp.
4539 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
4541 Fix minor problem found by static checking.
4542 * buffer.c (Fdelete_all_overlays): Return nil.
4544 2012-09-03 Martin Rudalics <rudalics@gmx.at>
4546 * buffer.c (Fdelete_all_overlays): New function.
4548 2012-09-03 Chong Yidong <cyd@gnu.org>
4550 * gtkutil.c: Add extern decl for Qxft.
4552 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
4554 * emacs.c, eval.c: Use bool for boolean.
4555 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
4556 (malloc_using_checking) [DOUG_LEA_MALLOC]:
4557 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
4558 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
4559 (main, decode_env_path, Fdaemon_initialized):
4560 * eval.c (call_debugger, Finteractive_p, interactive_p):
4561 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
4562 (maybe_call_debugger, Fbacktrace):
4563 * process.c (read_process_output, exec_sentinel):
4564 Use bool for booleans.
4565 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
4566 All callers changed.
4567 * eval.c (interactive_p): Omit always-true boolean argument
4568 EXCLUDE_SUBRS_P. All callers changed.

4574 * msdos.c (fatal_error_in_progress): ... from here.
4575 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead

4578 REDISPLAYING_P when unwinding, instead of saving its previous,
4579 always-false value and then restoring it.
4581 Clean up some extern decls.
4582 Mostly, this hoists extern decls out of .c files and into .h files.
4583 That way, we're more likely to catch errors if the interfaces change.

4669 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
4670 more than one grapheme cluster passed to the shaper: compute the
4671 offset adjustment values separately for each cluster. (Bug#11860)
4673 * image.c: Restore mistakenly removed inclusion of w32.h. Without
4674 it, GCC doesn't see prototypes of w32_delayed_load, and complains
4675 about implicit conversions from integer to pointer.
4677 2012-09-01 Daniel Colascione <dancol@dancol.org>
4679 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window

4733 window system declarations.
4735 * frame.h: Move common functions here: set_frame_menubar,
4736 x_set_window_size, x_sync, x_get_focus_frame,
4737 x_set_mouse_position, x_set_mouse_pixel_position,
4738 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

4799 * lread.c (init_lread): For out-of-tree builds, only add the
4800 source directory's site-lisp dir to the load-path if it exists,
4801 consistent with in-tree builds. (Bug#12302)
4803 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

4824 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
4825 Add window_closed and button_values. Add void as return value for
4826 add(Button|String|Split). addButton takes int instead of Lisp_Object.
4827 Add process_dialog as new member.

5017 (string_escape_byte8):
5018 * charset.c (charset_map_loaded, load_charset_map, read_hex):
5019 (load_charset_map_from_file, map_charset_chars)
5020 (Fdefine_charset_internal, define_charset_internal)
5021 (Fdeclare_equiv_charset, find_charsets_in_text)
5022 (Ffind_charset_region, char_charset, Fiso_charset):
5023 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
5024 (sub_char_table_set, sub_char_table_set_range)
5025 (char_table_set_range, optimize_sub_char_table)
5026 (map_sub_char_table):
5027 Use bool for boolean.
5028 * character.c (str_to_unibyte): Omit last boolean argument; it was
5029 always 0. All callers changed.
5030 * character.h, charset.h: Adjust to match previous changes.
5031 * character.h (char_printable_p): Remove decl of nonexistent function.
5032 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
5033 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
5034 are all boolean, so make them single-bit bitfields.
5036 * lisp.h (ASET): Remove attempt to detect side effects.
5037 It was meant to be temporary and it often doesn't work,
5038 because when IDX has side effects the behavior of IDX==IDX
5039 is undefined. See Stefan Monnier in
5040 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
5042 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
5044 * lisp.h (functionp): New function (extracted from Ffunctionp).
5045 (FUNCTIONP): Use it.
5046 * eval.c (Ffunctionp): Use it.
5048 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
5050 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
5051 as that's faster and simpler than static storage. Don't bother
5052 with the g_main_context_query overhead if g_main_context_pending
5053 says no events are pending.
5054 (gfds, gfds_size): Remove these static vars.
5055 (xgselect_initialize): Remove; no longer needed.
5056 All uses and decls removed.
5058 * emacs.c (fatal_error_signal_hook): Remove.
5059 All uses removed. This leftover from old code was always 0.
5061 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
5062 * casefiddle.c (casify_object, casify_region):
5063 * casetab.c (set_case_table):
5064 * category.c, category.h (word_boundary_p):
5065 * category.h (CHAR_HAS_CATEGORY):
5066 Use bool for booleans, instead of int.
5068 2012-08-25 Eli Zaretskii <eliz@gnu.org>
5070 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
5072 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
5074 On assertion failure, print backtrace if available.
5075 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
5076 (die) [ENABLE_CHECKING]: Print a backtrace if available.
5077 * Makefile.in (LIB_EXECINFO): New macro.
5080 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
5081 * bytecode.c (exec_byte_code):
5082 * callint.c (check_mark, Fcall_interactively):
5083 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
5084 (getenv_internal, sync_process_alive, call_process_exited):
5085 * lisp.h (USE_SAFE_ALLOCA):
5086 Use bool for booleans, instead of int.
5087 * lisp.h, process.h: Adjust prototypes to match above changes.
5088 * callint.c (Fcall_interactively): Don't assume the mark's
5089 offset fits in 'int'.
5091 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
5093 * buffer.c, buffer.h: Use bool for boolean.
5094 * buffer.c (reset_buffer_local_variables)
5095 (buffer_lisp_local_variables, Fset_buffer_modified_p)
5096 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
5097 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
5098 (overlay_touches_p, overlay_strings, Foverlay_put)
5099 (report_overlay_modification, call_overlay_mod_hooks):
5100 (mmap_enlarge, mmap_set_vars):
5101 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
5102 Use bool for booleans, instead of int.
5103 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
5104 since the 1-or-0 return value is always ignored anyway.
5105 (mmap_initialized_p):
5106 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
5107 * buffer.h, lisp.h: Adjust prototypes to match above changes.
5109 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5111 * bidi.c: Use bool for boolean.
5112 This is a bit more readable, and makes the text segment of bidi.o
5113 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
5114 Presumably it's faster too.
5115 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
5117 (bidi_cache_find_level_change, bidi_cache_iterator_state)
5118 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
5119 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
5120 (bidi_explicit_dir_char, bidi_level_of_next_char)
5121 (bidi_find_other_level_edge, bidi_move_to_visually_next):
5122 Use bool for booleans, instead of int.
5123 * dispextern.h (bidi_init_it, bidi_paragraph_init)
5124 (bidi_unshelve_cache): Adjust decls to match code.
5126 2012-08-23 Martin Rudalics <rudalics@gmx.at>
5128 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
5131 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5133 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
5134 * atimer.h: Include <stdbool.h>.
5136 2012-08-22 Dan Nicolaescu <dann@gnu.org>
5138 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
5139 compile time tests instead of run time tests on systems that do
5141 (FRAME_MAC_P): Remove leftover from deleted code.
5142 * frame.c (syms_of_frame): Remove leftover from deleted code.
5144 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
5146 * nsterm.m (insertText:): Don't clear modifiers if code is space.
5148 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
5150 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
5151 Otherwise, the compiler complains about (A?B:C) where B is void
5152 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
5153 (fontset_add): Return void, for FONTSET_ADD.
5155 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5157 * alloc.c: Use bool for booleans.
5158 (gc_in_progress, abort_on_gc)
5159 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5160 (dont_register_blocks) [GC_MALLOC_CHECK]:
5161 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
5162 (check_string_bytes, make_specified_string, memory_full)
5163 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
5164 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
5165 (mark_stack, valid_pointer_p, make_pure_string)
5166 (Fgarbage_collect, survives_gc_p, gc_sweep):
5167 Use bool for booleans, instead of int.
5168 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5169 Remove unused local.
5170 * alloc.c (PURE_POINTER_P):
5171 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
5172 * editfns.c (Fformat):
5173 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
5175 * fns.c (sweep_weak_table):
5176 * lisp.h (suppress_checking, push_message, survives_gc_p)
5177 (make_pure_string, gc_in_progress, abort_on_gc):
5178 * lread.c (readchar, read1):
5179 * print.c (Fprin1_to_string):
5180 * xdisp.c (push_message):
5181 Use bool for booleans affected directly or indirectly by
5184 Make recently-introduced setters macros.
5185 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
5186 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
5187 (set_fontset_default, set_fontset_fallback): Rename from their
5188 upper-case counterparts, and make them functions rather than macros.
5189 This is more consistent with the other recently-introduced setters.
5190 These don't need to be inline, since they're local.
5192 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
5194 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
5195 the loop (Bug#12247).
5197 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5199 * lisp.h (vcopy): Use memcpy rather than our own loop.
5200 This fixes a performance regression introduced by the recent
5201 addition of vcopy. This means 'vcopy' will need to be modified
5202 for a copying collector, but that's OK. Also, tighten the
5203 checking in the assertion.
5205 2012-08-21 Eli Zaretskii <eliz@gnu.org>
5207 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
5208 components for RTL text (Bug#11860). Adjust X-OFFSET of each
5209 non-base glyph for the width of the base character, according to
5210 what x_draw_composite_glyph_string_foreground expects.
5211 Generate WADJUST value according to composition_gstring_width's
5212 expectations, to produce correct width of the composed character.
5213 Reverse the sign of the DU offset produced by ScriptPlace.
5215 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5217 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
5219 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
5221 Avoid direct writes to contents member of struct Lisp_Vector.
5222 * lisp.h (vcopy): New function to copy data into vector.
5223 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
5224 * fns.c (Ffillarray): Use ASET.
5225 * keyboard.c (timer_check_2): Use AREF and ASET.
5226 (append_tool_bar_item, Frecent_keys): Use vcopy.
5227 * lread.c (read_vector): Use ASET.
5228 * msdos.c (Frecent_doskeys): Use vcopy.
5229 * xface.c (Finternal_copy_lisp_face): Use vcopy.
5230 (Finternal_merge_in_global_face): Use ASET and vcopy.
5231 * xfont.c (xfont_list_pattern): Likewise.
5233 2012-08-21 Martin Rudalics <rudalics@gmx.at>

5236 the position of its buffer's point.
5237 (Fset_window_point): For the selected window always go in its
5238 buffer to the specified position.
5240 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
5242 Setter macros for fontsets.
5243 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
5244 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
5245 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
5248 2012-08-20 Glenn Morris <rgm@gnu.org>
5250 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
5251 Don't assume that `ln -f' works.
5253 2012-08-20 Eli Zaretskii <eliz@gnu.org>
5255 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
5256 and later about non-assignments with no effect. See discussion at
5257 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
5260 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5262 Inline setter functions for Lisp_Objects slots of struct specbinding.
5263 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
5266 2012-08-20 Martin Rudalics <rudalics@gmx.at>
5268 * window.c (select_window): Always make selected window's buffer
5271 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5273 Use AREF and ASET for docstrings of category tables.
5274 * category.h (CATEGORY_DOCSTRING): Use AREF.
5275 (SET_CATEGORY_DOCSTRING): Use ASET.
5276 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
5278 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5280 Inline setter functions for hash table members.
5281 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
5282 (set_hash_hash, set_hash_index): Rename with _slot suffix.
5283 (set_hash_key_and_value, set_hash_index, set_hash_next)
5284 (set_hash_hash): New functions.
5285 * charset.c, fns.c: Adjust users.
5287 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5289 Inline getter and setter functions for per-buffer values.
5290 * buffer.h (per_buffer_default, set_per_buffer_default)
5291 (per_buffer_value, set_per_buffer_value): New functions.
5292 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
5293 * buffer.c, data.c: Adjust users.
5295 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
5297 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
5299 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
5301 Rely on <config.h> + <unistd.h> to declare 'environ',
5302 as gnulib does this if the system doesn't.
5303 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
5304 Remove declaration. MS-Windows declares it on stdlib.h which is
5305 included by conf_post.h.
5306 * emacs.c (environ) [DOUG_LEA_MALLOC]:
5307 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
5308 * vm-limit.c: Include <unistd.h>, for 'environ'.
5310 * unexaix.c, unexcoff.c: Include "mem-limits.h".
5311 (start_of_data): Remove decl; mem-limits.h provides it.
5313 * xdisp.c (handle_invisible_prop): Make it a bit faster
5314 and avoid a gcc -Wmaybe-uninitialized diagnostic.
5316 2012-08-19 Chong Yidong <cyd@gnu.org>
5318 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
5321 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
5323 * .gdbinit: Use call instead of set when calling a function in the
5326 * data.c (set_internal): Don't use set_blv_found.
5327 (Fkill_local_variable): Likewise.
5329 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
5331 * nsfont.m (ns_ascii_average_width): Ensure the string
5332 ascii_printable is initialized with a null-terminated character
5333 array. Otherwise, it can contain undesired extra characters.
5335 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
5337 port new setting code to Sun C 5.8 2005/10/13
5338 * chartab.c, lisp.h (char_table_set, char_table_set_range):
5339 Return void, not Lisp_Object. Otherwise, the compiler
5340 complains about (A?B:C) where B is void and C is Lisp_Object
5341 when compiling CHAR_TABLE_SET, due to the recent change to
5342 the API of sub_char_table_set_contents.
5344 2012-08-18 Chong Yidong <cyd@gnu.org>
5346 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
5347 for the string case (Bug#3874).
5349 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
5351 * buffer.h (BSET): Remove (Bug#12215).

5421 New setter functions.
5423 * termhooks.h (TSET): Remove (Bug#12215).

5425 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
5426 (TERMHOOKS_INLINE): New macro.
5427 (tset_charset_list, tset_selection_alist): New setter functions.
5428 * terminal.c (TERMHOOKS_INLINE):
5429 Define to EXTERN_INLINE, so that the corresponding functions
5430 are compiled into code.
5431 (tset_param_alist): New setter function.
5433 2012-08-17 Paul Eggert <eggert@cs.ucla.edu>
5435 * keyboard.h (KSET): Remove (Bug#12215).

6179 value of EMACSLOADPATH, as it is no longer needed.
6180 (check_windows_init_file): Now external, not static.
6181 Use Vload_path as is, without adding anything, as this function is now
6182 called when Vload_path is already set up.

6186 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

6231 * alloc.c (record_xmalloc): New function.
6232 * lisp.h (record_xmalloc): New decl.
6233 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
6234 more like a function. This is because the pointer cast is not
6235 needed. All uses changed.
6236 * print.c (print_string, print_error_message): Avoid length recalc.
6238 Improve fix for macroexp crash with debugging (Bug#12118).
6239 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
6240 ARRAY_MARK_FLAG when checking subscripts, because ASET is
6241 not supposed to be invoked from the garbage collector.
6242 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
6243 (gc_aset): New function, which is like ASET but can be
6244 used in the garbage collector.

6273 with addition of handling of symlinks and support for 'lstat'.
6274 If possible, get file's attributes and security information by
6275 handle, not by name. Produce S_IFLNK bit for symlinks, when
6276 called from 'lstat'.
6277 (stat, lstat): New functions, call 'stat_worker'.
6278 (symlink, readlink, careadlinkat): Rewritten to create and resolve
6279 symlinks when the underlying filesystem supports them.
6281 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
6283 Fix macroexp crash on Windows with debugging (Bug#12118).
6284 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
6285 checking subscripts; problem introduced with the recent
6286 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
6287 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
6288 since it's used in non-static inline functions now.
6290 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
6291 Don't assume buffer size fits in 'int'. Remove unused local.

6317 (INLINE_HEADER_END): New macros.
6318 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

6783 arms of an 'if', not using conditional expressions; otherwise GDB
6784 complains about the types in the unevaluated arm when the argument
6785 is an integer literal.
6786 (xgetint): Simplify expression.
6787 * alloc.c (gdb_make_enums_visible): New constant. This ports to
6788 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
6789 Zaretskii in <http://bugs.gnu.org/12036#13>.
6790 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
6791 needed now that we have gdb_make_enums_visible.
6792 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
6793 (enum enum_USE_LSB_TAG):
6794 New enum types, packaging up enums that need to be exported to GDB.
6796 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
6798 Utility function to make a list from specified amount of objects.

6800 (listn): New prototype.
6801 * alloc.c (listn): New function.
6802 (Fmemory_use_count, syms_of_alloc): Use it.

6812 * xdisp.c (syms_of_xdisp): Likewise.
6813 * xfns.c (syms_of_xfns): Likewise.
6815 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
6817 Fast save_excursion_save and save_excursion_restore.
6818 * lisp.h (struct Lisp_Excursion): New data type.
6819 (PVEC_EXCURSION): New pseudovector type.
6820 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
6821 to deal with it. Adjust comments.
6822 (init_marker, attach_marker): New prototype.
6823 (unchain_marker): Adjust prototype.
6824 * marker.c (attach_marker): Change to global.

6832 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
6834 Fix export of symbols to GDB (Bug#12036).
6835 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
6836 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
6837 emacs.c, as this is a more-suitable home. Had this been done earlier
6838 the fix for 12036 would have avoided some of the problems noted in
6839 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
6840 would have been more obvious.
6841 * emacs.c: Do not include <verify.h>; no longer needed.
6842 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
6843 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
6844 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
6845 Remove; now done in lisp.h.
6846 * lisp.h (PUBLISH_TO_GDB): New macro.
6847 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
6848 (DATA_SEG_BITS): Use it.
6849 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
6850 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
6851 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
6852 not be usable in #if. This simplifies things.
6854 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
6856 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
6858 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
6860 Simplify export of symbols to GDB (Bug#12036).
6861 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
6862 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
6863 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
6864 Adjust to changes in lisp.h and emacs.c, by using
6865 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
6866 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
6867 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
6868 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
6869 instead of gdb_valbits.
6870 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
6871 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
6872 instead of gdb_array_mark_flag.
6873 (xboolvector): Get size from $->size, not $->header.size.
6874 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
6875 (xreload, hook-run, hookpost-run): Remove.
6876 * emacs.c: Include <verify.h>.
6877 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
6878 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
6880 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
6881 (gdb_USE_LSB_TAG): New enum constants.
6882 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
6883 Also define these as enum constants, so they're visible to GDB.
6884 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
6885 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
6886 as constants, so they're visible to GDB.
6887 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
6888 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
6889 Now enum constants, not macros, so they're visible to GDB.
6890 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
6891 more convenient now. All uses changed.
6892 (VALMASK) [USE_LSB_TAG]: Also define in this case.
6893 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
6895 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

6900 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
6902 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
6903 add argument, tune behavior, and adjust all callers.
6905 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
6907 Use typedef for EMACS_INT, EMACS_UINT.
6908 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
6909 than macros. This simplifies debugging in the usual case, since
6910 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
6911 and it allows expressions involving EMACS_INT casts.
6912 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
6914 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
6916 * nsterm.m (ns_read_socket): Return early if there is a modal

6922 that FOCUS-FRAME can be omitted.
6924 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
6926 Adjust buffer text indirection counters at the end of Fkill_buffer.
6927 * buffer.c (Fkill_buffer): Adjust indirection counters when the
6928 buffer is definitely dead. This should really fix an issue reported
6929 by Christoph Scholtes again. (Bug#12007).
6930 (init_buffer_once): Initialize indirection counters of
6931 buffer_defaults and buffer_local_symbols (for sanity and safety).
6933 2012-07-24 Eli Zaretskii <eliz@gnu.org>
6935 * xdisp.c (init_iterator): Don't compute dimensions of truncation
6936 and continuation glyphs on tooltip frames, leave them at zero.
6937 Avoids continued lines in tooltips. (Bug#11832)
6939 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
6941 Simplify copy_overlay.
6942 * buffer.c (copy_overlay): Simplify. Use build_marker.

6964 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
6966 Swap buffer text indirection counters in Fbuffer_swap_text.
6967 * buffer.c (Fbuffer_swap_text): Swap indirections too.
6968 This avoids crash reported by Christoph Scholtes at
6969 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
6971 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
6973 * nsmenu.m (Popdown_data): New struct.
6974 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
6976 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.

6978 and autorelease them. Also autorelease img and matrix (Bug#12005).
6979 (dealloc): Remove (Bug#12005).

6996 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
6998 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
6999 as it's limited by the amount of memory, not by INT_MAX.
7001 2012-07-21 Eli Zaretskii <eliz@gnu.org>
7003 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
7004 in special-event-map. See the discussion at

7064 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
7065 Adjust users accordingly.
7066 * font.h (font_open_by_name): Adjust prototype.
7068 2012-07-20 Dmitry Antipov <dmantipov@yandex.ru>

7085 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
7086 'for_each_per_buffer_object_at'.
7087 All uses changed. It's better to use upper-case for macros that
7088 cannot be implemented as functions, to give the reader a clue
7089 that they're special.
7091 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>

7134 * intervals.c (merge_interval_right, merge_interval_left):
7135 Do not zero out this interval if it is absorbed by its children,
7136 as this interval's total length doesn't change in that case. See
7137 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00403.html>.
7139 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
7141 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
7142 when invoking (make-bool-vector N t) and N is a positive

7145 Remove some struct layout assumptions in bool vectors.
7146 * alloc.c (bool_header_size): New constant.
7147 (header_size, word_size): Move earlier, as they're now used earlier.

7150 padding before the data member of a bool vector.
7151 (sweep_vectors): Use PSEUDOVECTOR_TYPEP, in an eassert, rather
7152 than doing the check by hand with an abort ().
7154 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
7156 * eval.c (Fdefvar): Don't check constants since we only set the var if
7157 it's not yet defined anyway (bug#11904).
7159 * lisp.h (last_undo_boundary): Declare new var.
7160 * keyboard.c (command_loop_1): Set it.
7161 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
7162 were auto-added by the command loop (bug#11774).
7164 2012-07-18 Andreas Schwab <schwab@linux-m68k.org>
7166 * w32font.c (Qsymbol): Remove local definition.

7667 * s/gnu.h: Remove file, which is now empty.
7669 * s/gnu.h, s/gnu-linux.h:
7670 Move GNU_LIBRARY_PENDING_OUTPUT_COUNT to configure.
7672 2012-07-11 John Wiegley <johnw@newartisans.com>
7674 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
7675 function attribute, so we only use it if it exists in the
7678 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
7680 Avoid call to strlen in fast_c_string_match_ignore_case.
7681 * search.c (fast_c_string_match_ignore_case): Change to use
7682 length argument. Adjust users accordingly.
7683 * lisp.h (fast_c_string_match_ignore_case): Adjust prototype.
7685 2012-07-11 Paul Eggert <eggert@cs.ucla.edu>

7726 Remove "#define unix" that is no longer needed (Bug#11905).
7727 * s/aix4-2.h (unix): Remove; no longer needed.
7729 EMACS_TIME simplification (Bug#11875).
7730 This replaces macros (which typically do not work in GDB)
7731 with functions, typedefs and enums, making the code easier to debug.
7732 The functional style also makes code easier to read and maintain.
7733 * systime.h: Include <sys/time.h> on all hosts, not just if
7734 WINDOWSNT, since 'struct timeval' is needed in general.
7735 (EMACS_TIME): Now a typedef, not a macro.
7736 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
7738 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

7741 (EMACS_TIME_LE): Now functions, not macros.
7742 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
7743 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
7744 which are not functions. All uses rewritten to use:
7745 (make_emacs_time): New function.
7746 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
7747 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
7748 not functions. All uses rewritten to use the following, respectively:
7749 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
7750 (add_emacs_time, sub_emacs_time): New functions.
7751 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
7752 * fileio.c (Fcopy_file):
7753 * xterm.c (XTflash): Get the current time closer to when it's used.
7754 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

7761 * frame.c (Fmake_terminal_frame):
7762 * gtkutil.c (get_utf8_string):
7764 * nsmenu.m (ns_update_menubar):
7765 * regex.c (regerror):
7766 Prefer memcpy to strncpy and strncat when either will do.
7767 * fileio.c (Fsubstitute_in_file_name):
7768 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
7769 (menu_separator_name_p):
7770 * nsmenu.m (ns_update_menubar):
7771 Prefer memcmp to strncmp when either will do.
7772 * nsterm.m: Include <ftoastr.h>.
7774 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
7775 Prefer snprintf to strncpy.
7776 * nsterm.m (ns_term_init):
7777 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
7778 * nsterm.m (ns_term_init):
7779 Avoid the need for strncpy, by using build_string or
7780 make_unibyte_string directly. Use dtoastr, not snprintf.
7781 * process.c (Fmake_network_process): Diagnose service names that
7782 are too long, rather than silently truncating them or creating
7783 non-null-terminated names.
7784 (Fnetwork_interface_info): Likewise, for interface names.
7785 * sysdep.c (system_process_attributes) [GNU_LINUX]:
7786 Prefer sprintf to strncat.
7787 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
7788 Prefer vsnprintf to vsprintf + strncpy.
7790 2012-07-10 Glenn Morris <rgm@gnu.org>
7792 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
7793 Clarify fallback case.
7795 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
7797 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
7798 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
7799 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
7800 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
7801 where argument type is known to be a Lisp_Cons.
7803 2012-07-10 Tom Tromey <tromey@redhat.com>
7805 * bytecode.c (BYTE_CODE_THREADED): New macro.
7806 (BYTE_CODES): New macro. Replaces all old byte-code defines.

7813 Optimize pure C strings initialization.
7814 * lisp.h (make_pure_string): Fix prototype.
7815 (build_pure_c_string): New function, defined as static inline. This
7816 provides a better opportunity to optimize away calls to strlen when
7817 the function is called with compile-time constant argument.
7818 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
7819 argument, adjust users accordingly. Use build_pure_c_string where
7821 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
7822 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
7823 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
7825 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
7827 Avoid calls to strlen in miscellaneous functions.
7828 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
7829 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
7830 * lread.c (openp): Likewise.
7832 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
7834 Avoid calls to strlen in path processing functions.
7835 * fileio.c (file_name_as_directory): Add comment. Change to add
7836 srclen argument and return the length of result. Adjust users
7838 (directory_file_name): Fix comment. Change to add srclen argument,
7839 swap 1st and 2nd arguments to obey the common convention.
7840 Adjust users accordingly.
7841 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
7843 2012-07-10 Glenn Morris <rgm@gnu.org>
7845 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
7846 Move PENDING_OUTPUT_COUNT definition to configure.
7848 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
7849 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
7850 * s/gnu.h (DATA_START): Move definitions to configure.
7852 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
7853 We include usg5-4-common.h, which defines them both.
7855 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
7856 O_RDONLY already includes it).
7858 Stop ns builds setting the EMACSLOADPATH environment variable.
7859 * nsterm.m (ns_load_path): Rename from ns_init_paths.
7860 Now it does not set EMACSLOADPATH, just returns the load-path string.
7861 * nsterm.h: Update accordingly.
7862 * lread.c [HAVE_NS]: Include nsterm.h.
7863 (init_lread) [HAVE_NS]: Use ns_load_path.
7864 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
7866 2012-07-09 Glenn Morris <rgm@gnu.org>
7868 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
7869 since the included bsd-common.h does so.
7871 Stop ns builds setting the EMACSPATH environment variable.
7872 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
7873 (ns_init_paths): Do not set EMACSPATH.
7874 * nsterm.h (ns_exec_path): Add it.
7875 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
7878 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
7880 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
7882 * process.c (wait_reading_process_output): 'waitchannels' was unset
7883 when read_kbd || !NILP (wait_for_cell); fix this.
7885 Add GCC-style 'const' attribute to functions that can use it.
7886 * character.h (char_resolve_modifier_mask):
7887 * keyboard.h (make_ctrl_char):
7888 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
7889 (init_character_once, next_almost_prime, init_fns, init_image)
7890 (flush_pending_output, init_sound):

7895 Declare the dummy function with ATTRIBUTE_CONST.
7896 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
7897 Add decls with ATTRIBUTE_CONST.
7899 Minor improvements to make_formatted_string.
7900 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
7901 where int is good enough, as vsprintf returns an int.
7902 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
7904 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7906 Use make_formatted_string to avoid double length calculation.
7907 * lisp.h (make_formatted_string): New prototype.

7914 (x_report_frame_params): Likewise.
7915 * image.c (gs_load): Likewise.
7916 * minibuf.c (get_minibuffer): Likewise.

7931 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7933 Move marker debugging code under MARKER_DEBUG.
7934 * marker.c (MARKER_DEBUG): Move marker debugging code under
7935 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
7936 for bootstrap with --enable-checking (~3x slowdown reported
7937 by Juanma Barranquero <lekktu@gmail.com>).
7938 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
7940 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
7942 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
7943 See <http://bugs.gnu.org/11825#29>.
7945 2012-07-08 Eli Zaretskii <eliz@gnu.org>
7947 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
7948 has no font, use the frame's font. (Bug#11813)
7949 (display_line): Add commentary about displaying truncation glyphs
7951 (produce_special_glyphs): Move here from term.c.
7953 * term.c (produce_special_glyphs): Move to xdisp.c.
7955 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
7958 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
7960 * xdisp.c (display_line): Avoid warning about implicit declaration
7963 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
7965 * lisp.h: Remove empty conditional.
7967 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
7969 * lread.c (load_path_check): Now static.
7971 Fix some minor --with-ns problems found by static checking.
7972 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
7973 (x_set_font) [!HAVE_X_WINDOWS]:
7974 * image.c (xpm_load_image) [HAVE_NS]:
7975 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
7976 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
7977 Remove unused local.
7978 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
7979 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.

7981 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
7982 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
7983 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
7984 Fix pointer signedness problem.
7985 * xfaces.c (FRAME_X_FONT_TABLE):
7986 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
7988 2012-07-07 Glenn Morris <rgm@gnu.org>
7990 * lread.c (load_path_check): New function, split from init_lread.
7991 (init_lread): Reorganize. Motivation:
7992 If EMACSLOADPATH is set, check/warn about that rather than the
7993 defaults, which we are not going to use. Hence we can remove
7994 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
7995 Don't warn if site-lisp directories are missing.
7996 If not installed, start from a blank load-path, since
7997 PATH_LOADSEARCH refers to the eventual installation directories.
7999 2012-07-07 Eli Zaretskii <eliz@gnu.org>
8001 Support truncation and continuation glyphs on GUI frames, when
8002 fringes are disabled. (Bug#11832)
8003 * xdisp.c (init_iterator): Get dimensions of truncation and
8004 continuation glyphs even if on GUI frames.
8005 Adjust it->last_visible_x on GUI frames when the left or right fringes,
8006 or both, are absent.
8007 (start_display, move_it_in_display_line_to): Handle the case of a
8008 GUI frame without a fringe to display continuation or truncation
8010 (insert_left_trunc_glyphs): Support GUI frames: make sure
8011 truncation glyphs overwrite enough glyphs from the current line to
8012 have sufficient space in pixels.
8013 (display_line): Support truncation and continuation glyphs on GUI
8014 frames. If some spare pixels are left on the line after inserting
8015 the truncation glyphs, fill that space with a stretch glyph of a
8016 suitably computed width.
8018 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
8019 produce_glyphs, to support GUI sessions.
8021 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8023 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
8025 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
8027 Do not require float-time's arg to fit in time_t (Bug#11825).
8028 This works better on hosts where time_t is unsigned, and where
8029 float-time is applied to the (negative) difference between two times.
8030 * editfns.c (decode_time_components): Last arg is now double *,
8031 not int *, and means to store all the result as a double, without
8032 worrying about whether the seconds part fits in time_t.
8033 All callers changed.
8034 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
8035 All callers changed.
8036 (Ffloat_time): Do not fail merely because the specified time falls
8037 outside of time_t range.

8047 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
8048 Update dependencies.
8050 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
8052 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8054 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
8055 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
8056 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
8057 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
8058 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
8059 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
8061 * xfont.c (compare_font_names): Redo to omit the need for casts.
8063 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
8065 * xfns.c (Fx_change_window_property): Doc fix.
8066 * w32fns.c (Fx_change_window_property): Doc fix.
8068 * w32fns.c (Fx_window_property): Accept the same arguments as the
8069 X Windows version. Doc fix.
8070 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
8072 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
8073 Eli Zaretskii <eliz@gnu.org>
8075 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
8076 Windows-specific code from nt/config.nt moved here.
8077 Obsolete settings removed.
8079 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8081 * process.c: Avoid unnecessary calls to gettime.
8082 (wait_reading_process_output): Don't get the time of day
8083 when gobbling data immediately and not waiting, as there's no need
8084 for it in that case. This removes a FIXME.
8086 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
8088 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
8089 is defined (Bug#11768).
8091 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8093 Fix marker debugging code.
8094 * marker.c (byte_char_debug_check): Do not perform the check
8095 if buffer is not multibyte.
8096 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8097 Call byte_char_debug_check with correct arguments.
8099 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8101 Compile marker debugging code only if ENABLE_CHECKING is defined.
8102 * marker.c (byte_char_debug_check, count_markers):
8103 Use only if ENABLE_CHECKING is defined.
8104 (byte_debug_flag): Remove.
8105 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8106 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
8108 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8110 Avoid code repetition in marker-related functions.
8111 * marker.c (attach_marker): New function.
8112 (Fset_marker, set_marker_restricted, set_marker_both)
8113 (set_marker_restricted_both): Use it.
8114 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
8115 Consistently rename charno to charpos.
8116 (marker_position): Add eassert.
8117 (marker_byte_position): Convert to eassert.
8119 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8121 Simplify list operations in unchain_overlay and unchain_marker.
8122 * buffer.c (unchain_overlay): Simplify. Add comment.
8123 * marker.c (unchain_marker): Simplify. Fix comments.
8125 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8127 Introduce fast path for the widely used marker operation.
8128 * alloc.c (build_marker): New function.
8129 * lisp.h (build_marker): New prototype.
8130 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
8131 * composite.c (autocmp_chars): Likewise.
8132 * editfns.c (buildmark): Remove.
8133 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
8134 (save_restriction_save): Use build_marker.
8135 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
8136 * window.c (save_window_save): Likewise.
8138 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

8141 to avoid redundant calls to unchain_overlay.
8142 * buffer.c (drop_overlay): New function.
8143 (delete_all_overlays, Fdelete_overlay): Use it.
8144 * minibuf.c (get_minibuffer): Fix comment.
8146 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8148 Port to OpenBSD 5.1 amd64.
8149 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
8150 This is needed for OpenBSD, and should be harmless on all BSD systems.
8151 Also, include <sys/sysctl.h>, as it should be available on all
8152 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
8153 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
8154 use p_pid member, not kp_proc.pid.
8156 2012-07-06 Glenn Morris <rgm@gnu.org>
8158 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
8160 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
8162 More xmalloc and related cleanup.
8163 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

8170 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
8171 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
8173 Omit needless casts involving void * pointers and allocation.
8174 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
8175 as the former is more robust if P's type is changed.
8176 Prefer xzalloc to xmalloc + memset 0.
8177 Simplify malloc-or-realloc to realloc.
8178 Don't worry about xmalloc returning a null pointer.
8179 Prefer xstrdup to xmalloc + strcpy.
8180 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
8182 * keyboard.c (apply_modifiers_uncached): Prefer local array to
8183 alloca of a constant.
8185 2012-07-05 Eli Zaretskii <eliz@gnu.org>
8187 * xdisp.c (display_line): Fix horizontal pixel coordinates when
8188 hscroll is larger than the line width. Fixes long and futile
8189 looping inside extend_face_to_end_of_line (on a TTY) producing
8190 glyphs that are not needed and thrown away.
8192 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
8194 * marker.c (set_marker_restricted_both): Simplify by using
8197 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
8199 * editfns.c (region_limit): Simplify by using clip_to_bounds.
8201 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
8203 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
8204 not defined (Bug#11768).
8205 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
8206 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
8207 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
8208 followed by gtk_box_set_homogeneous (Bug#11768).
8209 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
8210 (update_theme_scrollbar_width, xg_create_scroll_bar):
8211 Use gtk_scrollbar_new (Bug#11768).
8212 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
8213 (is_box_type): New function (Bug#11768).
8214 (xg_tool_item_stale_p): Call is_box_type.
8215 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
8216 with default display (Bug#11768).

8220 * xdisp.c (window_hscroll_limited): New function.
8221 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
8222 coordinates when window's hscroll is set to insanely large
8225 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
8227 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

8230 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
8233 * lisp.h (xzalloc): New prototype. Omit needless casts.
8234 * alloc.c (xzalloc): New function. Omit needless casts.

8286 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
8288 * fileio.c (time_error_value): Check the right error number.
8289 Problem reported by Troels Nielsen in
8290 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
8292 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8294 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
8295 This should be fixed in a better way; see Eli Zaretskii in
8296 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
8297 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
8299 * fileio.c (time_error_value): Rename from special_mtime.
8300 The old name's problems were noted by Eli Zaretskii in
8301 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
8303 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
8304 This variable's comment says Emacs needs at least one GDB-visible
8305 symbol of type enum pvec_type, to work around GDB problems.
8306 The symbol's value doesn't matter.
8308 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
8309 that causes compilation to fail on pre-C99 compilers.
8311 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
8313 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
8314 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
8316 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8318 * buffer.c (init_buffer_once): Fix initialization of
8319 headers for buffer_defaults and buffer_local_symbols.
8320 Reported by Juanma Barranquero <lekktu@gmail.com>.
8322 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
8324 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
8325 * lisp.h (enum pvec_type): Use fewer bits.
8326 (PSEUDOVECTOR_SIZE_BITS): New constant.
8327 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
8328 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
8329 change in pvec_type.
8330 (PSEUDOVECTOR_TYPEP): New macro.
8331 (TYPED_PSEUDOVECTORP): Use it.
8332 * fns.c (internal_equal): Adapt code to extract pvectype.

8336 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
8337 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
8338 (sweep_vectors): Use it. Use local var `total_bytes' instead of
8339 abusing vector->header.next.nbytes.
8340 (live_vector_p): Use PVEC_TYPE.
8341 (mark_object): Adapt code to extract pvectype. Use switch.
8343 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8345 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
8346 Tighten new eassert a bit.
8348 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8350 Fix compilation with --enable-gcc-warnings and -O1
8352 * doprnt.c (doprnt): Change type of tem to int, initialize
8353 to avoid compiler warning. Add eassert.
8354 * search.c (simple_search): Initialize match_byte to avoid
8355 compiler warning. Add eassert.
8357 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8359 Avoid weird behavior with large horizontal scrolls.
8360 Without this change, for example, large hscroll values would
8361 mess up Emacs's display on Fedora 15 x86, presumably due to
8362 overflows in int calculations in the display code.
8363 Also, if buffers had long lines, Emacs would freeze.
8364 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
8365 (set_window_hscroll): New function, containing the old guts of
8366 Fset_window_hscroll. Return the clipped value.
8367 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
8368 This avoids the need to check against PTRDIFF_MAX.
8370 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
8372 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8374 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
8376 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8378 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
8379 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
8380 since GCC 4.4.6 issues a bogus warning for them.
8382 Fix bugs in file timestamp newness comparisons.
8383 * fileio.c (Ffile_newer_than_file_p):
8384 * lread.c (Fload): Use full timestamp resolution of files,
8385 not just the 1-second resolution, so that files that are only
8386 slightly newer still count as newer.
8387 * fileio.c (Ffile_newer_than_file_p): Don't assume file
8388 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
8390 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
8392 * fileio.c: Improve handling of file time marker. (Bug#11852)
8393 (special_mtime): New function.
8394 (Finsert_file_contents, Fverify_visited_file_modtime):
8395 Use it to set special mtime values consistently.
8397 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
8399 * fileio.c (Finsert_file_contents): Properly handle st_mtime
8400 marker for non-existing file. (Bug#11852)
8402 2012-07-03 Glenn Morris <rgm@gnu.org>
8404 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
8405 and did not make it into globals.h).
8407 2012-07-03 Tom Tromey <tromey@redhat.com>
8409 * window.c (Fset_window_margins, Fset_window_fringes)
8410 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
8411 * textprop.c (Fprevious_property_change): No longer static.
8412 * syntax.c (Fsyntax_table_p): No longer static.
8413 * process.c (Fget_process, Fprocess_datagram_address): No longer

8427 * dired.c (Ffile_attributes): No longer static.
8428 * composite.c (Fcomposition_get_gstring): No longer static.
8429 * callproc.c (Fgetenv_internal): No longer static.
8431 * ccl.h: Remove EXFUNs.

8433 * dispextern.h: Remove EXFUNs.
8434 * intervals.h: Remove EXFUNs.
8435 * fontset.h: Remove EXFUN.
8436 * font.h: Remove EXFUNs.
8437 * dosfns.c (system_process_attributes): Remove EXFUN.
8438 * keymap.h: Remove EXFUNs.
8439 * lisp.h: Remove EXFUNs.
8440 * w32term.h: Remove EXFUNs.
8441 * window.h: Remove EXFUNs.
8442 * xsettings.h: Remove EXFUN.
8443 * xterm.h: Remove EXFUN.
8445 2012-07-03 Glenn Morris <rgm@gnu.org>
8447 * lisp.h (Frandom): Make it visible to C.
8448 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
8449 buffer for invisible buffers. (Bug#1229)
8451 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8453 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
8454 values which aren't power of 2.
8455 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
8456 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
8459 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
8461 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
8463 * alloc.c (mark_object): Revert part of last patch to use `switch'.
8465 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8467 * alloc.c (allocate_vector_block): Remove redundant
8468 calls to mallopt if DOUG_LEA_MALLOC is defined.
8469 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
8470 avoid calls to mallopt if zero_vector is returned.
8472 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8474 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
8475 is enabled, avoid dereferencing NULL current_sblock if
8478 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8480 Cleanup basic buffer management.
8481 * buffer.h (struct buffer): Change layout to use generic vector
8482 marking code. Fix some comments. Change type of 'clip_changed'
8483 to bitfield. Remove unused #ifndef old.
8484 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
8485 (GET_OVERLAYS_AT): Fix indentation.
8486 (for_each_per_buffer_object_at): New macro.
8487 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
8488 (Fbuffer_local_variables): Use it.
8489 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
8490 * alloc.c (allocate_buffer): Adjust to match new layout of
8491 struct buffer. Fix comment.
8492 (mark_overlay): New function.
8493 (mark_buffer): Use it. Use mark_vectorlike to mark normal
8494 Lisp area of struct buffer.
8495 (mark_object): Use it. Adjust marking of misc objects
8496 and related comments.
8498 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
8500 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
8501 wrapper that is not needed because the wrapped code is a no-op (zero
8502 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
8503 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
8505 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
8507 * alloc.c (mark_buffer): Simplify. Remove prototype.
8508 (mark_object): Add comment. Reorganize marking of vector-like
8509 objects. Use CHECK_LIVE for all vector-like objects except buffers
8510 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
8511 Avoid redundant calls to mark_vectorlike for bool vectors.
8513 2012-06-30 Glenn Morris <rgm@gnu.org>
8515 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
8517 * epaths.in (PATH_SITELOADSEARCH): New.
8518 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
8519 This is rather than relying on --enable-locallisppath elements
8520 having "site-lisp" in their names. (Bug#10208#25, 11658)
8522 2012-06-30 Eli Zaretskii <eliz@gnu.org>
8524 * w32proc.c (sys_select): Accept and ignore one more argument.
8526 * w32.c (emacs_gnutls_pull): Call select with one more argument.
8528 * sysselect.h [DOS_NT]: Don't include sys/select.h.
8529 (pselect) [!MS_DOS]: Redirect to sys_select.
8531 * sysdep.c: Don't include dos.h and dosfns.h.
8533 * process.c (sys_select):
8534 * msdos.c (sys_select): Accept one more argument and ignore it.
8536 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
8537 adapt data types and code to that.
8540 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
8541 which clashes with the gnulib function of the same name.
8543 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
8545 * font.c (font_style_to_value, font_style_symbolic)
8546 (font_prop_validate_style): Add type checks for values in
8549 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
8551 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
8554 2012-06-29 Eli Zaretskii <eliz@gnu.org>
8556 * xdisp.c (try_window_id): Undo last change.
8558 * w32.c (getwd): Adjust commentary about startup_dir.
8559 (init_environment): Always call sys_access, even in non-MSVC
8560 builds. Don't chdir to the directory of the Emacs executable.
8561 This undoes code from 1997 which was justified by the need to
8562 "avoid conflicts when removing and renaming directories". But its
8563 downside was that every relative file name was being interpreted
8564 relative to the directory of the Emacs executable, which can never
8565 be TRT. In particular, it broke sys_access when called with
8566 relative file names.
8567 (sys_access): Map GetLastError to errno.
8569 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8571 * window.h (struct window): Change type of 'fringes_outside_margins'
8572 to bitfield. Fix comment. Adjust users accordingly.
8573 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
8575 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
8578 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
8580 * gnutls.c (emacs_gnutls_handshake):
8581 Add QUIT to make the loop interruptible.
8583 2012-06-29 Glenn Morris <rgm@gnu.org>
8585 * charset.c (init_charset): Make lack of etc/charsets fatal.

8761 Use sprintf return value instead of invoking strlen on result.
8762 In the old days this wasn't portable, since some sprintf
8763 implementations returned char *. But they died out years ago and
8764 Emacs already assumes sprintf returns int.
8765 Similarly for float_to_string.
8766 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

8774 Use sprintf or float_to_string result to avoid need to call strlen.
8775 * data.c (Fnumber_to_string):
8776 Use make_unibyte_string, since the string must be ASCII.
8777 * lisp.h, print.c (float_to_string): Now returns int length.
8778 * term.c (produce_glyphless_glyph):
8779 Use sprintf result rather than recomputing it.
8781 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
8782 * Makefile.in (ALL_CFLAGS):
8783 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

8808 sprintf already null-terminates its output.
8810 * xfns.c (x_window): Remove redundant cast.
8812 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
8814 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
8815 `const char *' to `char *' to avoid compiler warning.
8817 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
8819 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
8820 instead of truncating it to 63 (admittedly a generous limit).

8875 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
8877 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).

8879 * dispnew.c (Fsleep_for, sit_for):
8880 * keyboard.c (kbd_buffer_get_event):
8881 * process.c (Faccept_process_output):
8882 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
8883 This improves on the previous patch, which introduced a bug
8884 when time_t is unsigned and as wide as intmax_t.
8885 See <http://bugs.gnu.org/9000#51>.
8887 2012-06-23 Eli Zaretskii <eliz@gnu.org>

8950 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
8952 Support higher-resolution time stamps (Bug#9000).
8953 The time stamps are only nanosecond-resolution at the C level,
8954 since that's the best that any real-world system supports now.
8955 But they are picosecond-resolution at the Lisp level, as that's
8956 easy, and leaves room for future OS improvements.
8958 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
8961 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
8962 Don't get current time unless it's needed.
8964 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
8965 now provides it if it's absent.
8966 (start_atimer): Port to higher-res time stamps.
8967 Check for time stamp overflow. Don't get current time more
8968 often than is needed.
8970 * buffer.h (struct buffer): Buffer modtime now has high resolution.
8971 Include systime.h, not time.h.
8972 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
8974 * dired.c: Include stat-time.h.
8975 (Ffile-attributes): File times now have higher resolution.

8978 (struct image): Timestamp now has higher resolution.
8980 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
8981 has at least microseconds now. All uses removed.
8982 (update_frame, update_single_window, update_window, update_frame_1)
8983 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
8984 (duration_to_sec_usec): Remove; no longer needed.
8986 * editfns.c (time_overflow): Now extern.
8987 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
8988 (float-time, Fformat_time_string, Fcurrent_time_string)

8992 (decode_time_components, lisp_seconds_argument): New functions.
8993 (make_time): Now static.
8994 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
8995 Report an error if the time is invalid, rather than having the caller
8998 * fileio.c: Include <stat-time.h>
8999 (Fcopy_file): Copy higher-resolution time stamps.
9000 Prefer to set the time stamp via a file descriptor if that works.
9001 (Fset_file_times, Finsert_file_contents, Fwrite_region)
9002 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
9003 (Fvisited_file_modtime, Fset_visited_file_modtime):
9004 Support higher-resolution time stamps.
9006 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
9008 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
9010 * image.c (prepare_image_for_display, clear_image_cache)
9011 (lookup_image): Port to higer-resolution time stamps.
9013 * keyboard.c (start_polling, bind_polling_period):
9014 Check for time stamp overflow.
9015 (read_char, kbd_buffer_get_event, timer_start_idle)
9016 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
9017 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
9018 Port to higher-resolution time stamps. Do not assume time_t is signed.
9019 (decode_timer): New function. Timers are now vectors of length 9,
9020 not 8, to accommodate the picosecond component.
9021 (timer_check_2): Use it.
9023 * nsterm.m (select_timeout, timeval_subtract): Remove.
9024 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
9025 as they're a bit more accurate and handle overflow better.
9026 (ns_select): Change prototype to be compatible with pselect.
9027 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
9028 * nsterm.h (ns_select): Adjust prototype.
9030 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
9031 us-resolution time stamps.
9032 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
9034 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
9036 * lisp.h (time_overflow): New decl.
9037 (wait_reading_process_output): First arg is now intmax_t, not int,
9038 to accommodate larger waits.
9040 * process.h (struct Lisp_Process.read_output_delay):
9041 Now counts nanoseconds, not microseconds.
9042 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
9044 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
9045 (wait_reading_process_output):
9046 Port to ns-resolution time stamps.
9047 (Faccept_process_output, wait_reading_process_output):
9048 Check for time stamp overflow. Do not assume time_t is signed.
9049 (select_wrapper): Remove; we now use pselect.
9050 (Fprocess_attributes): Now generates ns-resolution time stamps.
9052 * sysdep.c: Include utimens.h. Don't include utime.h
9053 or worry about struct utimbuf; gnulib does that for us now.
9054 (gettimeofday): Remove; gnulib provides a substitute.
9055 (make_timeval): New function.
9056 (set_file_times): Now sets ns-resolution time stamps.
9057 New arg FD; all uses changed.
9058 (time_from_jiffies, ltime_from_jiffies, get_up_time)
9059 (system_process_attributes):
9060 Now returns ns-resolution time stamp. All uses changed.
9061 Check for time stamp overflow.
9063 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
9064 provides a substitute now.
9066 * systime.h: Include timespec.h rather than sys/time.h and time.h,
9067 since it guarantees struct timespec.
9068 (EMACS_TIME): Now struct timespec, so that we can support
9069 ns-resolution time stamps.
9070 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
9071 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
9072 (EMACS_USECS): Remove.
9073 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
9074 so multiply the arg by 1000 before storing it.
9075 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):

9084 (make_timeval, make_lisp_time, decode_time_components): New decls.
9085 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in

9127 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
9128 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,

9180 gets killed during executing of this function (Bug#11665).

9183 run by this hook should not change the current buffer.
9185 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

9545 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
9547 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
9549 * doprnt.c (doprnt): Truncate multibyte char correctly.
9550 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
9551 would mishandle a string argument "Xc" if X was a multibyte
9552 character of length 2: it would truncate after X's first byte
9553 rather than including all of X.
9555 2012-06-06 Chong Yidong <cyd@gnu.org>
9557 * buffer.c (word_wrap): Doc fix.
9559 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>
9561 * xdisp.c (note_mode_line_or_margin_highlight): Pacify gcc -Wall.

9570 (temacs$(EXEEXT)): Disable memory randomization for the temacs
9571 binary via PaX flags if the paxctl utility is available.
9572 (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
9573 Restore PaX flags to their default. (Bug#11398)
9575 2012-06-03 Chong Yidong <cyd@gnu.org>
9577 * xdisp.c (decode_mode_spec_coding): Display a space for a unibyte
9580 2012-06-03 Chong Yidong <cyd@gnu.org>
9582 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
9583 (note_mode_line_or_margin_highlight): If there is no help echo,
9584 use mode-line-default-help-echo. Handle the case where the mouse
9585 position is past the end of the mode line string.
9587 * buffer.c (buffer_local_value_1): New function, split from
9588 Fbuffer_local_value; can return Qunbound.
9589 (Fbuffer_local_value): Use it.
9590 (Vmode_line_format): Docstring tweaks.
9592 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
9594 * sysdep.c (system_process_attributes): Improve comment.
9596 2012-06-02 Stefan Monnier <monnier@iro.umontreal.ca>
9598 * keyboard.c: Export real-this-command to Elisp.
9599 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
9600 and DEFVAR it. Update all users.
9602 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
9604 * minibuf.c (Fassoc_string): Remove duplicate declaration.
9606 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
9607 Convert pctcpu and pctmem to Lisp float properly.
9608 Let the compiler fold better, as 100.0/0x8000 is exact.
9610 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
9612 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
9615 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
9617 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
9619 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
9621 For a 'struct window', replace some Lisp_Object fields to
9622 bitfields where appropriate, remove unused fields.
9623 * window.h (struct window): Remove unused 'last_mark_x' and
9624 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
9625 change its type from Lisp_Object to bitfield.
9626 Change type of 'force_start', 'optional_new_start',
9627 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
9628 fields from Lisp_Object to bitfield. Adjust users accordingly.
9630 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
9632 Pacify gcc -Wdouble-precision when using Xaw.
9633 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
9634 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
9635 Use 'float' consistently, rather than 'float' in most places
9636 and 'double' in a couple of places.
9638 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9640 * xdisp.c (handle_stop): Detect whether we have overlay strings
9641 loaded by testing it->current.overlay_string_index to be
9642 non-negative, instead of checking whether n_overlay_strings is
9643 positive. (Bug#11587)
9645 2012-05-31 Chong Yidong <cyd@gnu.org>
9647 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
9649 * doc.c (Fsubstitute_command_keys): Doc fix.
9651 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9653 * search.c (search_buffer): Remove calls to
9654 r_alloc_inhibit_buffer_relocation, as it is now called by
9655 maybe_unify_char, which was the cause of relocation of buffer text
9658 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9660 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
9661 for the duration of call to load_charset, to avoid problems with
9662 callers of maybe_unify_char that access buffer text through C
9665 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
9666 decrement the inhibition flag, instead of just setting or
9669 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
9671 Remove obsolete '#define static' cruft.
9672 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
9673 This #undef was "temporary" in 2000; it is no longer needed
9674 now that '#define static' has gone away.
9675 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
9676 (gray_bitmap_bits): Remove; no longer needed.
9677 All uses replaced with definiens.
9678 * xterm.c: Include "bitmaps/gray.xbm".
9680 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
9682 Clean up __executable_start, monstartup when --enable-profiling.
9683 The following changes affect the code only when profiling.
9684 * dispnew.c (__executable_start): Rename from safe_bcopy.
9685 Define only on platforms that need it.
9686 * emacs.c: Include <sys/gmon.h> when profiling.
9687 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
9688 (__executable_start): Remove decl, since lisp.h does it now.
9689 (safe_bcopy): Remove decl; no longer has that name.
9690 (main): Coalesce #if into single bit of code, for simplicity.
9691 Cast pointers to uintptr_t, since standard libraries want integers
9693 * lisp.h (__executable_start): New decl.
9695 2012-05-31 Glenn Morris <rgm@gnu.org>
9697 * image.c (Fimagemagick_types): Doc fix.
9699 2012-05-30 Jim Meyering <meyering@redhat.com>
9701 * callproc.c (Fcall_process_region): Include directory component
9702 in mkstemp error message (Bug#11586).
9704 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
9706 * alloc.c, lisp.h (make_pure_vector): Now static.
9708 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>

9711 Move to byte-run.el.
9712 (Fautoload): Do the hash-doc more carefully.
9713 * data.c (Fdefalias): Purify definition, except for keymaps.
9714 (Qdefun): Move from eval.c.
9715 * lisp.h (Qdefun): Remove.
9716 * lread.c (read1): Tiny simplification.
9718 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
9720 Do not create empty overlays with the evaporate property (Bug#9642).
9721 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
9722 Bug#9642, but explicitly check that the buffer the overlay would
9723 be moved to is live and rearrange lines to make sure that errors
9724 will not put the overlay in an inconsistent state.
9725 (Fdelete_overlay): Cosmetics.
9727 2012-05-28 Eli Zaretskii <eliz@gnu.org>
9729 * w32term.c (my_bring_window_to_top): New function.
9730 (x_raise_frame): Use handle returned by DeferWindowPos, which
9731 could be different from the original one.
9732 Call my_bring_window_to_top instead of my_set_foreground_window.
9735 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
9736 by calling BringWindowToTop.
9738 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
9739 (WM_EMACS_END): Increase by one.
9741 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
9743 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
9744 This avoids undefined behavior that might cause the eassert
9745 to not catch an out-of-range value.
9747 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
9749 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
9750 Update dependencies.
9752 2012-05-27 Eli Zaretskii <eliz@gnu.org>
9754 * bidi.c (bidi_mirror_char): Fix last change.
9756 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
9758 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
9759 when referring to sectname field in printf format.
9761 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
9763 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
9764 Only r_alloc_inhibit_buffer_relocation needed to be added;
9765 the others were already declared.
9767 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
9768 before checking whether it's out of range. Put the check inside
9770 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
9772 2012-05-27 Ken Brown <kbrown@cornell.edu>
9774 * callproc.c (Fcall_process): Restore a line that was accidentally
9775 commented out in the 2011-02-13 change (bug#11547).
9777 2012-05-27 Eli Zaretskii <eliz@gnu.org>
9779 * lisp.h [REL_ALLOC]: Add prototypes for external functions
9780 defined on ralloc.c.
9782 * buffer.c [REL_ALLOC]: Remove prototypes of
9783 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
9784 they are now on lisp.h.
9786 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
9788 * search.c (search_buffer): Use it to inhibit relocation of buffer
9789 text while re_search_2 is doing its job, because re_search_2 is
9790 passed C pointers to buffer text. (Bug#11519)
9792 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
9795 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
9796 state after an additional call to move_it_in_display_line_to, keep
9797 the values of it->max_ascent and it->max_descent found for the
9799 (pos_visible_p): Revert the comparison against bottom_y to what it
9800 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
9803 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
9805 Fix coding-related core dumps with gcc -ftrapv.
9806 The code was computing A - B, where A and B are pointers, and B is
9807 random garbage. This can lead to core dumps on platforms that
9808 have special pointer registers, and it also leads to core dumps on
9809 x86-64 when compiled with gcc -ftrapv. The fix is to compute
9810 A - B only when B is initialized properly.
9811 * coding.c (coding_set_source, coding_set_destination): Return void.
9812 (coding_change_source, coding_change_destinations): New functions,
9813 with the old behaviors of coding_set_source and coding_set_destination.
9814 All callers that need an offset changed to use these new functions.
9816 2012-05-26 Glenn Morris <rgm@gnu.org>
9818 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
9820 2012-05-26 Eli Zaretskii <eliz@gnu.org>
9822 Extend mouse support on W32 text-mode console.
9823 * xdisp.c (draw_row_with_mouse_face):
9824 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
9826 * w32console.c: Include window.h.
9827 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
9829 (initialize_w32_display): Initialize mouse-highlight data.
9831 * w32inevt.c: Include termchar.h and window.h.
9832 (do_mouse_event): Support mouse-autoselect-window. When the mouse
9833 moves, call note_mouse_highlight. If help_echo changed, call
9834 gen_help_event to produce help-echo message in the echo area.
9835 Call clear_mouse_face if mouse_face_hidden is set in the mouse
9838 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
9840 * lread.c (read1): Simplify slightly to avoid an overflow warning
9841 with GCC 4.7.0 on x86-64.
9843 2012-05-26 Eli Zaretskii <eliz@gnu.org>
9845 * bidi.c (bidi_mirror_char): Revert last change: an int is
9846 definitely wide enough here.
9848 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
9850 Fix integer width and related bugs (Bug#9874).
9851 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
9852 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
9853 (string_bytes, check_sblock, allocate_string_data):
9854 (compact_small_strings, Fmake_bool_vector, make_string)
9855 (make_unibyte_string, make_multibyte_string)
9856 (make_string_from_bytes, make_specified_string)
9857 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
9858 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
9860 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9861 (allocate_pseudovector):
9862 Use int, not EMACS_INT, where int is wide enough.
9863 (inhibit_garbage_collection, Fgarbage_collect):
9864 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9865 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
9866 int might not be wide enough.
9867 (bidi_cache_search, bidi_cache_find, bidi_init_it)
9868 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
9869 (bidi_at_paragraph_end, bidi_find_paragraph_start)
9870 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
9871 (bidi_level_of_next_char, bidi_move_to_visually_next):
9872 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9873 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
9874 (Fkill_buffer, Fset_buffer_major_mode)
9875 (advance_to_char_boundary, Fbuffer_swap_text)
9876 (Fset_buffer_multibyte, overlays_at, overlays_in)
9877 (overlay_touches_p, struct sortvec, record_overlay_string)
9878 (overlay_strings, recenter_overlay_lists)
9879 (adjust_overlays_for_insert, adjust_overlays_for_delete)
9880 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
9881 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
9882 (Foverlay_recenter, last_overlay_modification_hooks_used)
9883 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
9884 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9885 (validate_region): Omit unnecessary test for b <= e,
9886 since that's guaranteed by the previous test.
9887 (adjust_overlays_for_delete): Avoid pos + length overflow.
9888 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
9889 (report_overlay_modification):
9890 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9891 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
9892 Omit pointer cast, which isn't needed anyway, and doesn't work
9893 after the EMACS_INT -> ptrdiff_t change.
9894 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
9895 * buffer.h: Adjust decls to match defn changes elsewhere.
9896 (struct buffer_text, struct buffer):
9897 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9898 Use EMACS_INT, not int, where int might not be wide enough.
9899 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
9900 not int, to avoid needless 32-bit limit on 64-bit hosts.
9901 (exec_byte_code): Use tighter memory-full test, one that checks
9902 for alloca overflow. Don't compute the address of the object just
9903 before an array, as that's not portable. Use EMACS_INT, not
9904 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
9905 * callint.c (Fcall_interactively):
9906 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9907 * callproc.c (call_process_kill, Fcall_process):
9908 Don't assume pid_t fits into an Emacs fixnum.
9909 (call_process_cleanup, Fcall_process, child_setup):
9910 Don't assume pid_t fits into int.
9911 (call_process_cleanup, Fcall_process, delete_temp_file)
9912 (Fcall_process_region):
9913 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9914 (Fcall_process): Simplify handling of volatile integers.
9915 Use int, not EMACS_INT, where int will do.
9916 * casefiddle.c (casify_object, casify_region, operate_on_word)
9917 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
9918 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9919 (casify_object): Avoid integer overflow when overallocating buffer.
9920 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
9921 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
9922 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
9923 * category.h (CATEGORYP): Don't assume arg is nonnegative.
9924 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
9925 integers are now checked earlier. All uses replaced with XINT.
9927 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9928 For CCL_MapSingle, check that content and value are in int range.
9929 (ccl_driver, Fregister_code_conversion_map):
9930 Check that Vcode_version_map_vector is a vector.
9931 (resolve_symbol_ccl_program): Check that vector header is in range.
9932 Always copy the vector, so that we can check its contents reliably
9933 now rather than having to recheck each instruction as it's being
9934 executed. Check that vector words fit in 'int'.
9935 (ccl_get_compiled_code, Fregister_ccl_program)
9936 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
9937 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
9938 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
9939 contents are in range.
9940 (Fccl_execute_on_string): Check that status is in range.
9941 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
9942 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
9943 Accept and return EMACS_INT, not int, because callers can pass values
9945 (c_string_width, strwidth, lisp_string_width, chars_in_text)
9946 (multibyte_chars_in_text, parse_str_as_multibyte)
9947 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
9948 (str_as_unibyte, str_to_unibyte, string_count_byte8)
9949 (string_escape_byte8, Fget_byte):
9950 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9951 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
9952 avoid mishandling large integers.
9953 * character.h: Adjust decls to match defn changes elsewhere.
9954 * charset.c (load_charset_map_from_file, find_charsets_in_text)
9955 (Ffind_charset_region):
9956 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9957 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
9958 (load_charset_map_from_vector, Fdefine_charset_internal):
9959 Don't assume fixnum fits in int.
9960 (load_charset_map_from_vector, Fmap_charset_chars):
9961 Remove now-unnecessary CHECK_NATNUMs.
9962 (Fdefine_charset_internal): Check ranges here, more carefully.
9963 Don't rely on undefined behavior with signed left shift overflow.
9964 Don't assume unsigned int fits into fixnum, or that fixnum fits
9965 into unsigned int. Don't require max_code to be a valid fixnum;
9966 that's not true for gb10830 4-byte on a 32-bit host. Allow
9967 invalid_code to be a cons, for the same reason. Require code_offset
9968 to be a character. Avoid int overflow if max_char is close
9970 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
9971 this is intended anyway and avoids some undefined behavior.
9972 (load_charset_map): Pass unsigned, not int, as 2nd arg of
9973 INDEX_TO_CODE_POINT, as that's what it expects.
9974 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
9975 * charset.h (DECODE_CHAR): Return int, not unsigned;
9976 this is what was intended anyway, and it avoids undefined behavior.
9977 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
9978 integer-overflow issues.
9979 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
9980 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
9981 where the argument is EMACS_INT, and this behavior is not intended.
9982 * chartab.c (Fmake_char_table, Fset_char_table_range)

10658 (unreadpure): Remove function.
10659 (readevalloop): Don't call read_list with -1 flag.
10660 (read1, read_vector): Don't test read_pure any more.
10661 (read_list): Simplify.
10663 * fileio.c, character.h: Minor style tweaks.
10665 2012-05-24 Dmitry Antipov <dmantipov@yandex.ru>
10667 * window.h (clip_changed): Remove useless declaration.
10669 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
10671 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
10672 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
10674 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
10677 This directory predates autoconf and is no longer needed nowadays.
10678 Move its few remaining bits of functionality to where they're needed.
10679 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
10680 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
10681 * m/template.h: Remove.
10682 * Makefile.in (M_FILE): Remove. All uses removed.
10683 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
10684 * lisp.h (USE_LSB_TAG):
10685 * mem-limits.h (EXCEEDS_LISP_PTR):
10686 Use VAL_MAX, not VALBITS, in #if.
10687 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
10688 (EMACS_UINT): Define unconditionally now.
10689 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
10690 (BITS_PER_EMACS_INT): New constants, replacing
10691 what used to be in config.h, but not useful in #if.
10692 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
10693 define them any more.
10694 (VAL_MAX): New macro.
10696 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
10697 BITS_PER_EMACS_INT, in #if.
10698 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
10699 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
10700 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
10701 * s/ms-w32.h (DATA_START):
10702 Move here from removed file m/intel386.h.
10703 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
10704 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
10706 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
10708 Assume C89 or later.
10709 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
10710 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
10712 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
10713 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
10714 * textprop.c, tparam.c (NULL): Remove.
10715 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
10716 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
10717 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
10718 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
10719 * xterm.c (input_signal_count): Assume volatile works.
10721 2012-05-21 Ken Brown <kbrown@cornell.edu>
10723 * xgselect.c (xg_select): Fix first argument in call to 'select'
10726 2012-05-20 Ken Brown <kbrown@cornell.edu>
10728 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
10729 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
10731 2012-05-19 Ken Brown <kbrown@cornell.edu>
10733 * xfns.c (x_in_use): Remove `static' qualifier.
10734 * xterm.h (x_in_use): Declare.
10735 * xgselect.c: Include xterm.h.
10736 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
10737 and `display_arg' (bug#9754).
10739 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
10741 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
10743 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
10744 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
10746 2012-05-18 Eli Zaretskii <eliz@gnu.org>
10748 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
10750 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
10751 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
10753 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
10754 reference to image_cache->refcount.
10755 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
10757 2012-05-17 Juri Linkov <juri@jurta.org>
10759 * search.c (Fword_search_regexp, Fword_search_backward)
10760 (Fword_search_forward, Fword_search_backward_lax)
10761 (Fword_search_forward_lax): Move functions to isearch.el
10762 (bug#10145, bug#11381).
10764 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
10766 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
10768 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
10770 * lread.c (init_obarray): Declare Qt and Qnil as special.
10772 2012-05-14 Glenn Morris <rgm@gnu.org>
10774 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
10775 Put "libexec" before "bin", for the sake of init_callproc_1.
10777 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
10779 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
10781 * unexaix.c: Port to more-recent AIX compilers.
10782 (report_error, report_error_1, make_hdr, copy_sym)
10783 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
10784 Make arguments const char *, not char *, to avoid violations of C
10785 standard and to fix some AIX warnings reported by Gilles Pion.
10787 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10789 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
10790 already have overlays loaded.
10791 (handle_single_display_spec): Before returning without displaying
10792 fringe bitmap, synchronize the bidi iterator with the main display
10793 iterator, by calling iterate_out_of_display_property.
10794 (iterate_out_of_display_property): Detect buffer iteration by
10795 testing that it->string is a Lisp string.
10796 (get_next_display_element): When the current object is exhausted,
10797 and there's something on it->stack, call set_iterator_to_next to
10798 proceed with what's on the stack, instead of returning zero.
10799 (set_iterator_to_next): If called at the end of a Lisp string,
10800 proceed to consider_string_end without incrementing string
10801 position. Don't increment display vector index past the end of
10802 the display vector. (Bug#11417)
10803 (pos_visible_p): Don't report a position visible when move_it_to
10804 stopped at the last line of window, which happens to be scanned
10805 backwards by the bidi iteration. (Bug#11464)
10807 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10809 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
10810 and right-margin display specs even if the spec is invalid or we
10811 are on a TTY, and thus unable to display on the fringes.
10812 That's because the text with the property will not be displayed anyway,
10813 so we need to signal to the caller that this is a "replacing"
10814 display spec. This fixes display when the spec is invalid or we
10817 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
10819 * unexaix.c (make_hdr): Fix typo in prototype.
10820 This bug broke the build on AIX. Problem reported by Gilles Pion.
10822 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
10824 * keyboard.c (kbd_buffer_get_event): Read special events also in
10825 batch mode. (Bug#11415)
10827 2012-05-12 Glenn Morris <rgm@gnu.org>
10829 * ns.mk: Update for ns_appbindir no longer having trailing "/".
10831 2012-05-12 Eli Zaretskii <eliz@gnu.org>
10833 * lisp.mk (lisp): Add newcomment.elc.
10835 2012-05-12 Glenn Morris <rgm@gnu.org>
10837 * Makefile.in (MKDIR_P): New, set by configure.
10838 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
10840 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
10842 Remove unused function hourglass_started.
10843 * dispextern.h (hourglass_started):
10844 * w32fns.c (hourglass_started):
10845 * xdisp.c (hourglass_started): Remove.
10847 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
10849 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
10850 Update dependencies.
10852 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
10854 * xgselect.c (xg_select): Put maxfds+1 into a var.
10855 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
10857 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
10859 2012-05-10 Dave Abrahams <dave@boostpro.com>
10861 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
10862 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
10864 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
10866 * dbusbind.c (xd_registered_buses): New internal Lisp object.
10867 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
10868 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
10869 Initialize xd_registered_buses.
10871 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
10873 Untag more efficiently if USE_LSB_TAG.
10874 This is based on a proposal by YAMAMOTO Mitsuharu in
10875 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
10876 For an admittedly artificial (nth 8000 longlist) benchmark on
10877 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
10878 Emacs's overall text size by 1%.
10879 * lisp.h (XUNTAG): New macro.
10880 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
10881 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
10882 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
10883 * eval.c (Fautoload):
10884 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
10885 * frame.h (XFRAME): Use XUNTAG.
10887 Port recent dbusbind.c changes to 32-bit --with-wide-int.
10888 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
10889 Remove unportable assumptions about print widths of types like
10891 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
10892 intptr_t when converting between pointer and integer, to avoid GCC
10893 warnings about wrong width.
10895 2012-05-09 Eli Zaretskii <eliz@gnu.org>
10897 * w32proc.c (new_child): Force Windows to reserve only 64KB of
10898 stack for each reader_thread, instead of defaulting to 8MB
10899 determined by the linker. This avoids failures in creating
10900 subprocesses on Windows 7, see the discussion in this thread:
10901 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
10903 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
10905 Fix up display of the *Minibuf-0* buffer in the mini window.
10906 * keyboard.c (read_char): Don't clear the echo area if there's no
10908 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
10909 contents of *Minibuf-0*) if there's no message displayed in its stead.
10911 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
10913 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
10916 2012-05-06 Chong Yidong <cyd@gnu.org>
10918 * lisp.mk (lisp): Update.
10920 2012-05-05 Jim Meyering <meyering@redhat.com>
10922 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
10924 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
10926 * data.c (PUT_ERROR): New macro.
10927 (syms_of_data): Use it. Add new error type `user-error'.
10928 * undo.c (user_error): New function.
10929 (Fprimitive_undo): Use it.
10930 * print.c (print_error_message): Adjust print style for `user-error'.
10931 * keyboard.c (user_error): New function.
10932 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
10934 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
10936 Do not limit current-time-string to years 1000..9999.
10937 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
10938 (Fcurrent_time_string): Support any year that is supported by the
10939 underlying localtime representation. Don't use asctime, as it
10940 has undefined behavior for years outside the range -999..9999.
10942 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
10944 Fix race conditions involving setenv, gmtime, localtime, asctime.
10945 Without this fix, interrupts could mess up code that uses these
10946 nonreentrant functions, since setting TZ invalidates existing
10947 tm_zone or tzname values, and since most of these functions return
10948 pointers to static storage.
10949 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
10950 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
10951 Grow the critical sections to include not just invoking
10952 localtime/gmtime, but also accessing these functions' results
10953 including their tm_zone values if any, and any related TZ setting.
10954 (format_time_string): Last arg is now struct tm *, not struct tm **,
10955 so that the struct tm is saved in the critical section.
10956 All callers changed. Simplify allocation of initial buffer, partly
10957 motivated by the fact that memory allocation needs to be outside
10958 the critical section.
10960 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
10962 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
10963 with RESET_INTERVAL.
10965 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
10966 Remove duplicated buffer name initialization.
10968 2012-05-02 Jim Meyering <jim@meyering.net>
10970 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
10972 * xfns.c (x_window): Use xstrdup (Bug#11375).
10974 2012-05-02 Eli Zaretskii <eliz@gnu.org>
10976 * xdisp.c (pos_visible_p): If already at a newline from the
10977 display string before the 'while' loop, don't walk back the glyphs
10978 from it3.glyph_row. Solves assertion violation when the display
10979 string begins with a newline (egg.el). (Bug#11367)
10981 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
10983 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
10986 2012-05-01 Glenn Morris <rgm@gnu.org>
10988 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
10989 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
10990 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
10991 All were removed before 23.1.
10993 * dispnew.c: Remove HAVE_LIBNCURSES test;
10994 it is always true on relevant platforms.
10996 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
10997 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
10999 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
11001 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
11003 * .gdbinit (xpr): Remove checks for no longer existing misc types.
11004 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
11007 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
11009 Do not avoid creating empty evaporating overlays (Bug#9642).
11010 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
11011 That is, do not delete an evaporating overlay if it becomes
11012 empty after its bounds are adjusted to fit within its buffer.
11013 This fix caused other problems, and I'm reverting it until we get
11014 to the bottom of them.
11016 2012-04-27 Chong Yidong <cyd@gnu.org>
11018 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
11020 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11022 * xdisp.c (pos_visible_p): If the window start position is beyond
11023 ZV, start the display from buffer beginning. Prevents assertion
11024 violation in init_iterator when the minibuffer window is scrolled
11025 via the scroll bar.
11027 * window.c (window_scroll_pixel_based): Likewise.
11029 2012-04-27 Chong Yidong <cyd@gnu.org>
11031 * keymap.c (where_is_internal): Doc fix (Bug#10872).
11033 2012-04-27 Glenn Morris <rgm@gnu.org>
11035 * fileio.c (Fcopy_file, Fset_file_selinux_context):
11036 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
11038 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11040 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
11041 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
11043 2012-04-26 Eli Zaretskii <eliz@gnu.org>
11045 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
11046 display element, check also the underlying string or buffer
11047 character. (Bug#11341)
11049 * w32menu.c: Include w32heap.h.
11050 (add_menu_item): If the call to AppendMenuW (via
11051 unicode_append_menu) fails, disable Unicode menus only if we are
11052 running on Windows 9X/Me.
11054 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
11056 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
11057 (xgetint): Add missing shift for LSB tags.
11059 2012-04-24 Martin Rudalics <rudalics@gmx.at>
11061 * keyboard.c (read_char): Don't wipe echo area for select window
11062 events: These might get delayed via `mouse-autoselect-window'
11065 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
11067 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
11068 manipulation of :loaded-from data.
11070 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
11072 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
11073 now a cons (bug#11311).
11075 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
11077 Do not create empty overlays with the evaporate property (Bug#9642).
11078 * buffer.c (Fmove_overlay): Delete an evaporating overlay
11079 if it becomes empty after its bounds are adjusted to fit within
11080 its buffer. Without this fix, in a nonempty buffer (let ((o
11081 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
11082 yields an empty overlay that has the evaporate property, which is
11083 not supposed to happen.
11085 Fix minor GTK3 problems found by static checking.
11086 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
11087 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
11088 (struct _EmacsFixedClass, emacs_fixed_get_type):
11089 Move decls here from emacsgtkfixed.h, since they needn't be public.
11090 (emacs_fixed_get_type): Now static.
11091 (emacs_fixed_class_init): Omit unused local.
11092 (emacs_fixed_child_type): Remove; unused.
11093 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
11094 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
11095 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
11096 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)

11198 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
11200 * sysdep.c [__FreeBSD__]: Minor cleanups.
11201 (list_system_processes, system_process_attributes) [__FreeBSD__]:
11202 Use Emacs indenting style more consistently. Avoid some casts.

11228 * process.c (wait_reading_process_output): If EIO occurs on a pty,
11229 set the status to "failed" and ensure that sentinel is run.
11231 2012-04-20 Glenn Morris <rgm@gnu.org>
11233 * process.c (Fset_process_inherit_coding_system_flag)

11286 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
11287 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
11288 (NEED_MEM_INSERT): New macro.
11289 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
11290 Remove one incorrect comment and fix another.

11326 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
11327 * s/netbsd.h, s/sol2-6.h:
11328 Remove definition of GC_MARK_STACK, since the default now works.
11329 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:

11357 2012-04-11 Daniel Colascione <dancol@dancol.org>
11359 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
11360 against is gone. It's better to use vfork now so that when Cygwin
11361 gains a new, working vfork, we use it automatically (bug#10398).
11363 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

11416 * minibuf.c (Fread_variable): Callers changed.
11418 2012-04-09 Eli Zaretskii <eliz@gnu.org>
11420 * xdisp.c (set_cursor_from_row): If the display string appears in
11421 the buffer at position that is closer to point than the position
11422 after the display string, display the cursor on the first glyph of
11423 the display string. Fixes cursor display when a 'display' text
11424 property immediately follows invisible text. (Bug#11094)
11426 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
11428 composite.c: use 'double' consistently
11429 * composite.c (get_composition_id): Use 'double' consistently
11430 instead of converting 'float' to 'double' and vice versa; this is
11431 easier to understand and avoids a GCC warning.
11433 2012-04-09 Glenn Morris <rgm@gnu.org>
11435 * Makefile.in: Generate leim-list with bootstrap-emacs, in
11436 preparation for dumping it with emacs. (Bug#4789)

11485 Calls xmlCleanupParser only if libxml2 was loaded (or statically
11487 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
11488 Call init_libxml2_functions before calling libxml2 functions.
11489 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
11491 * emacs.c: Don't include libxml/parser.h.

11500 point, use it.vpos to compute how many lines to backtrack after
11501 move_it_to point. (Bug#11133)
11503 2012-04-06 Eli Zaretskii <eliz@gnu.org>
11505 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
11506 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
11507 about subtle differences between FETCH_CHAR* and STRING_CHAR*
11508 macros related to unification of CJK characters. For the details,
11509 see the discussion following the message here:
11510 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.

11523 * w32menu.c (is_simple_dialog): Properly check lisp types.
11526 2012-03-31 Eli Zaretskii <eliz@gnu.org>
11528 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
11529 position we get to after a call to move_it_to fails the
11530 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
11531 only if we wind up in a string from display property. (Bug#11063)
11533 * window.c (Fdelete_other_windows_internal): Invalidate the row
11534 and column information about mouse highlight, so that redisplay
11535 restores it after reallocating the glyph matrices. (Bug#7464)
11537 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
11538 string comes from a `display' text property, use the buffer
11539 position of that property as if we actually saw that position in
11541 (move_it_by_lines): Remove the assertion that
11542 "it->current_x == 0 && it->hpos == 0" which can be legitimately
11543 violated when there's a before-string at the beginning of a line.
11546 2012-03-30 Eli Zaretskii <eliz@gnu.org>
11548 * xdisp.c (append_space_for_newline): If the default face was
11549 remapped, use the remapped face for the appended newline.
11550 (extend_face_to_end_of_line): Use the remapped default face for
11551 extending the face to the end of the line.
11552 (display_line): Call extend_face_to_end_of_line when the default
11553 face was remapped. (Bug#11068)
11555 2012-03-29 Eli Zaretskii <eliz@gnu.org>
11557 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
11559 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
11561 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
11563 2012-03-27 Glenn Morris <rgm@gnu.org>
11565 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
11568 2012-03-26 Kenichi Handa <handa@m17n.org>
11570 * dispextern.h (struct glyph): Fix previous change. Change the
11571 bit length of glyphless.ch to 25 (Bug#11082).
11573 2012-03-26 Chong Yidong <cyd@gnu.org>
11575 * keyboard.c (Vselection_inhibit_update_commands): New variable.
11576 (command_loop_1): Use it; inhibit selection update for
11577 handle-select-window too (Bug#8996).
11579 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
11581 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
11583 2012-03-25 Kenichi Handa <handa@m17n.org>
11585 * dispextern.h (struct glyph): Change the bit length of
11586 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
11588 2012-03-24 Eli Zaretskii <eliz@gnu.org>
11590 * s/ms-w32.h (tzname): Include time.h before redirecting to
11591 _tzname. Fixes the MSVC build. (Bug#9960)
11593 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
11595 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
11598 * xterm.c (XTread_socket): Only modify handling_signal if
11599 !SYNC_INPUT. (Bug#11080)
11601 2012-03-23 Eli Zaretskii <eliz@gnu.org>
11603 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
11604 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
11605 when fetching a multibyte character consumes more bytes than
11606 CHAR_BYTES returns, due to unification of CJK characters in
11607 string_char. (Bug#11073)
11609 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
11611 * process.c (wait_reading_process_output): Handle pty disconnect
11612 by refraining from sending oneself a SIGCHLD (bug#10933).
11614 2012-03-22 Chong Yidong <cyd@gnu.org>

11619 Mark string as coming from a prefix property.
11620 (handle_face_prop): Use default face for prefix strings (Bug#4281).
11621 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
11623 2012-03-21 Chong Yidong <cyd@gnu.org>
11625 * xfaces.c (Vface_remapping_alist): Doc fix.
11627 2012-03-20 Eli Zaretskii <eliz@gnu.org>
11629 * w32proc.c (Fw32_set_console_codepage)
11630 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
11633 2012-03-20 Chong Yidong <cyd@gnu.org>
11635 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
11636 to reflect default non-nil value of redisplay-dont-pause.
11638 2012-03-19 Kenichi Handa <handa@m17n.org>
11640 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
11641 it fit in a valid range (Bug#11003).
11643 2012-03-18 Eli Zaretskii <eliz@gnu.org>
11645 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
11646 that is not from display property, accept the row as a "cursor
11647 row" if one of the string's character has a non-nil `cursor'
11648 property. Fixes cursor positioning when there are newlines in
11649 overlay strings, e.g. in icomplete.el. (Bug#11035)
11651 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
11653 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
11655 2012-03-12 Chong Yidong <cyd@gnu.org>
11657 * eval.c (inhibit_lisp_code): Rename from
11658 inhibit_window_configuration_change_hook; move from window.c.
11660 * xfns.c (unwind_create_frame_1, Fx_create_frame):
11661 * window.c (run_window_configuration_change_hook)
11662 (syms_of_window): Callers changed.

11673 is visible (Bug#10955).
11675 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
11677 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).

11681 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
11682 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
11685 2012-03-03 Glenn Morris <rgm@gnu.org>
11687 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
11689 2012-03-02 Eli Zaretskii <eliz@gnu.org>
11691 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
11692 position past the first glyph_row that ends at ZV. (Bug#10902)
11693 (redisplay_window, next_element_from_string): Fix typos in
11695 (redisplay_window): Pass to move_it_vertically the margin in
11696 pixels, not in screen lines.
11698 2012-03-02 Glenn Morris <rgm@gnu.org>
11700 * buffer.c (buffer-list-update-hook): Doc fix.
11702 2012-02-29 Eli Zaretskii <eliz@gnu.org>
11704 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
11705 push_it before setting up the iterator for the first overlay
11706 string, even if we have an empty string loaded.
11707 (next_overlay_string): If there's an empty string on the iterator
11708 stack, pop the stack. (Bug#10903)
11710 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
11712 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
11713 Suggested by Stefan Monnier in
11714 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
11715 * alloc.c (widen_to_Lisp_Object): New static function.
11716 (mark_memory): Also mark Lisp_Objects by fetching pointer words
11717 and widening them to Lisp_Objects. This would work even if
11718 USE_LSB_TAG is defined and wide integers are used, which might
11719 happen in a future version of Emacs.
11721 2012-02-25 Chong Yidong <cyd@gnu.org>
11723 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
11726 * xselect.c (Fx_selection_exists_p): Doc fix.
11727 (x_clipboard_manager_save_all): Print an informative message
11728 before saving to clipboard manager.
11730 2012-02-24 Chong Yidong <cyd@gnu.org>
11732 * keyboard.c (process_special_events): Handle all X selection
11733 requests in kbd_buffer, not just the next one (Bug#8869).
11735 2012-02-23 Chong Yidong <cyd@gnu.org>
11737 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
11738 call when setting menu-bar-lines and tool-bar-lines parameters.
11739 (unwind_create_frame_1): New helper function.
11741 * window.c (inhibit_window_configuration_change_hook): New var.
11742 (run_window_configuration_change_hook): Obey it.
11743 (syms_of_window): Initialize it.
11745 2012-02-22 Chong Yidong <cyd@gnu.org>
11747 * xterm.c (x_draw_image_relief): Add missing type check for
11748 Vtool_bar_button_margin (Bug#10743).
11750 2012-02-21 Chong Yidong <cyd@gnu.org>
11752 * fileio.c (Vfile_name_handler_alist): Doc fix.
11754 * buffer.c (Fget_file_buffer): Protect against invalid file
11755 handler return value.
11757 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
11759 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
11760 when computing $valmask.
11762 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
11763 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
11764 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
11765 It's useless in that case, and it can cause problems on hosts
11766 that allocate halves of EMACS_INT values separately.
11767 Reported by Dan Horák. Diagnosed by Andreas Schwab in
11768 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
11769 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
11770 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
11771 it avoids undefined behavior on hosts where shifting right by more
11772 than the word width has undefined behavior.
11774 2012-02-19 Chong Yidong <cyd@gnu.org>
11776 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
11777 (Funhandled_file_name_directory, Ffile_name_as_directory)
11778 (Fdirectory_file_name, Fexpand_file_name)
11779 (Fsubstitute_in_file_name): Protect against invalid file handler
11780 return values (Bug#10845).
11782 2012-02-18 Eli Zaretskii <eliz@gnu.org>
11784 * .gdbinit (pitx): Fix incorrect references to fields of the

11794 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
11796 2012-02-15 Chong Yidong <cyd@gnu.org>
11798 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
11799 marked as special. Also, starting docstrings with * is obsolete.

11812 * keymap.c (Fsingle_key_description): Handle char ranges.
11814 2012-02-12 Chong Yidong <cyd@gnu.org>
11816 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
11817 as that creates a dangerous corner case.
11819 * window.c (Fdelete_window_internal): Invalidate the mouse
11820 highlight (Bug#9904).
11822 2012-02-12 Glenn Morris <rgm@gnu.org>

11825 (Fx_get_selection_internal, Fx_disown_selection_internal)
11826 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
11827 * nsselect.m (Fx_own_selection_internal)
11828 (Fx_disown_selection_internal, Fx_selection_exists_p)
11829 (Fx_selection_owner_p, Fx_get_selection_internal):
11830 Sync docs and argument specs with the xselect.c versions.
11832 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
11834 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
11836 2012-02-11 Eli Zaretskii <eliz@gnu.org>
11838 * w32select.c (Fx_selection_exists_p): Sync doc string and
11839 argument list with xselect.c. (Bug#10783)

11850 * coding.c (produce_chars): Fix updating of src_end (Bug#10701).
11852 2012-02-07 Chong Yidong <cyd@gnu.org>
11854 * buffer.c (Fbuffer_local_variables)
11855 (buffer_lisp_local_variables): Handle unbound vars correctly;
11856 don't let Qunbound leak into Lisp.
11858 2012-02-07 Glenn Morris <rgm@gnu.org>
11860 * image.c (Fimagemagick_types): Doc fix.
11862 * image.c (imagemagick-render-type): Change it from a lisp object
11863 to an integer. Move the doc here from the lisp manual.
11864 Treat all values not equal to 0 the same.
11866 2012-02-06 Chong Yidong <cyd@gnu.org>
11868 * doc.c (store_function_docstring): Avoid applying docstring of

11883 Include --enable-checking, if specified, in the return value.
11885 2012-02-04 Martin Rudalics <rudalics@gmx.at>
11887 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
11888 after rounding frame sizes. (Bug#9723)

11892 * keyboard.c (adjust_point_for_property): Don't position point
11893 before BEGV. (Bug#10696)
11895 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
11897 Handle overflow when computing char display width (Bug#9496).
11898 * character.c (char_width): Return EMACS_INT, not int.
11899 (char_width, c_string_width): Check for overflow when
11900 computing the width; this is possible now that individual
11901 characters can have unbounded width. Problem introduced
11902 by merge from Emacs 23 on 2012-01-19.
11904 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
11906 * dbusbind.c (Fdbus_register_method): Mention the return value
11907 :ignore in the docstring.
11909 2012-02-02 Glenn Morris <rgm@gnu.org>
11911 * callproc.c (Fcall_process, Fcall_process_region): Doc fix.

11921 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
11922 0, do not call append_composite_glyph.
11924 2012-02-02 Kenichi Handa <handa@m17n.org>
11926 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
11928 (x_produce_glyphs): If the component of a composition is a null
11929 string, set it->pixel_width to 1 to avoid zero-width glyph.
11931 2012-02-01 Eli Zaretskii <eliz@gnu.org>
11933 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
11934 first 2 arguments are identical. This makes inserting large
11935 output from a subprocess an order of magnitude faster on
11936 MS-Windows, where all sbrk'ed memory is always contiguous.
11938 2012-01-31 Glenn Morris <rgm@gnu.org>
11940 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

11976 2012-01-21 Chong Yidong <cyd@gnu.org>
11978 * floatfns.c (Fcopysign): Make the second argument non-optional,
11979 since nil is not allowed anyway.
11981 2012-01-21 Andreas Schwab <schwab@linux-m68k.org>
11983 * process.c (read_process_output): Use p instead of XPROCESS (proc).

11990 Rewrite doc-strings.
11992 2012-01-19 Kenichi Handa <handa@m17n.org>
11994 * character.c (char_width): New function.
11995 (Fchar_width, c_string_width, lisp_string_width):
11996 Use char_width (Bug#9496).

12016 highlight ends on a newline. (Bug#10464)
12017 (mouse_face_from_buffer_pos): Fix off-by-one error in calculating
12018 he end column for display of highlight that ends on a newline

12551 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
12552 Otherwise, valgrind does not work on some platforms.
12553 Problem reported by Andreas Schwab in
12554 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
12555 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
12556 is set, removing the need for VIRT_ADDRESS_VARIES.
12557 (PURE_P): Use a more-efficient implementation that needs just one
12558 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
12559 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
12560 to 4 (xorl, subq, cmpq, setbe).
12561 * alloc.c (pure): Always extern now, since that's the
12562 VIRT_ADDR_VARIES behavior.
12563 (PURE_POINTER_P): Use a single comparison, not two, for
12564 consistency with the new puresize.h.
12565 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
12566 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

12574 behave as if the cursor position were at the window margin.
12576 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
12577 and the cursor position is out of bounds, behave as if the cursor
12578 position were at the window margin. (Bug#10075)
12580 2011-11-18 Chong Yidong <cyd@gnu.org>
12582 * window.c (Fwindow_combination_limit): Make first argument

12603 * xdisp.c (row_hash): New function, body extracted from
12604 compute_line_metrics.
12605 (compute_line_metrics): Call row_hash, instead of computing the
12608 * dispnew.c (verify_row_hash): Call row_hash for computing the
12609 hash code of a row, instead of duplicating code from xdisp.c.
12611 * dispextern.h (row_hash): Add prototype.
12613 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

12649 2011-11-14 Eli Zaretskii <eliz@gnu.org>
12651 * xdisp.c (display_line): Move the call to
12652 highlight_trailing_whitespace before the call to
12653 compute_line_metrics, since the latter needs to see the final
12654 faces of all the glyphs to compute ROW's hash value.
12655 Fixes assertion violations in row_equal_p. (Bug#10035)
12657 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
12659 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
12660 just return (bug#10044).

12664 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
12665 with user-defined heap size. Bump the default size of the temacs

12669 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
12670 current_matrix and desired_matrix. (Bug#9990)
12671 (verify_row_hash) [XASSERTS]: New function.

12718 Avoid some portability problems by eschewing 'extern inline' functions.
12719 The trivial performance wins aren't worth the portability hassles; see
12720 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
12722 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

12788 * xmenu.c (cleanup_widget_value_tree): New function.
12789 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

12796 (window_box_width, window_box_left, window_box_left_offset)
12797 (window_box_right, window_box_right_offset): Declare extern.
12798 Otherwise, these inline functions do not conform to C99 and
12799 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
12800 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
12801 * intervals.c (adjust_intervals_for_insertion)

12804 (static_offset_intervals): Remove.
12805 (offset_intervals): Rewrite using the old contents of
12806 static_offset_intervals. The old version didn't conform to C99

12946 2011-11-01 Martin Rudalics <rudalics@gmx.at>
12948 * window.c (temp_output_buffer_show): Don't use
12949 Vtemp_buffer_show_specifiers.
12950 (Vtemp_buffer_show_specifiers): Remove unused variable.
12952 2011-10-30 Eli Zaretskii <eliz@gnu.org>
12954 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
12955 past the beginning of the current glyph matrix.
12957 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
12959 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.
12960 (x_error_handler): Ignore BadMatch for X_SetInputFocus for
12961 HAVE_GTK3 (Bug#9869).
12963 * gtkutil.c (xg_win_to_widget, xg_event_is_for_menubar): Initialize
12964 type to GDK_NOTHING so valgrind does not complain (Bug#9901).
12966 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
12968 * xterm.c: Declare x_handle_net_wm_state to return int.
12969 (handle_one_xevent): Check if we are iconified but don't have
12970 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
12971 (get_current_wm_state): Return non-zero if not hidden,
12972 check for _NET_WM_STATE_HIDDEN (Bug#9893).
12973 (do_ewmh_fullscreen): Ignore return value from get_current_wm_state.
12974 (x_handle_net_wm_state): Return what get_current_wm_state returns.
12975 (x_term_init): Initialize dpyinfo->Xatom_net_wm_state_hidden.
12977 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
12979 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
12980 so that this new function doesn't get optimized away by a
12981 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
12983 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
12985 * frame.h (MOUSE_HL_INFO): Remove excess parens.
12987 2011-10-29 Eli Zaretskii <eliz@gnu.org>
12989 Fix the `xbytecode' command.
12990 * .gdbinit (xprintbytestr): New command.
12991 (xwhichsymbols): Rename from `which'; all callers changed.
12992 (xbytecode): Print the byte-code string as well.
12994 2011-10-29 Kim Storm <storm@cua.dk>
12996 * alloc.c (which_symbols): New function.
12998 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
13000 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
13003 2011-10-29 Glenn Morris <rgm@gnu.org>
13005 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
13006 Not clear what it was for, and it causes various bugs. (Bug#9839)
13008 2011-10-28 Eli Zaretskii <eliz@gnu.org>
13010 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
13011 possible random value that matches one of those tested as
13012 condition to clear the mouse face.
13014 2011-10-28 Chong Yidong <cyd@gnu.org>
13016 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
13018 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
13020 * window.c (make_window): Initialize phys_cursor_on_p.
13022 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
13024 * lisp.h (struct Lisp_Symbol): Update comments.
13026 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
13028 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
13030 2011-10-28 Eli Zaretskii <eliz@gnu.org>
13032 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
13033 <oslsachem@gmail.com> for helping to debug this.
13035 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
13036 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
13037 (g_b_init_get_glyph_outline_w): New static variables.
13038 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
13039 (GetGlyphOutlineW_Proc): New typedefs.
13040 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
13041 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
13043 (w32font_open_internal, compute_metrics):
13044 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
13045 instead of calling the "wide" APIs directly.
13047 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
13049 * w32.h (syms_of_w32font): Add prototype.
13051 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
13053 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
13054 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
13055 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
13056 (Fmove_to_window_line): Doc fix.
13058 2011-10-27 Chong Yidong <cyd@gnu.org>
13060 * process.c (make_process): Set gnutls_state to NULL.
13062 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
13063 non-NULL, regardless of GNUTLS_INITSTAGE.
13064 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
13065 an error. Set process slots as soon as we allocate them.
13067 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
13069 2011-10-27 Chong Yidong <cyd@gnu.org>
13071 * gnutls.c (emacs_gnutls_deinit): New function.
13072 Deallocate credentials structures as well as calling gnutls_deinit.
13073 (Fgnutls_deinit, Fgnutls_boot): Use it.
13075 * process.c (make_process): Initialize GnuTLS credentials to NULL.
13076 (deactivate_process): Call emacs_gnutls_deinit.
13078 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
13080 * image.c (x_create_x_image_and_pixmap):
13081 * w32.c (sys_rename, w32_delayed_load):
13082 * w32font.c (fill_in_logfont):
13083 * w32reg.c (x_get_string_resource): Silence compiler warnings.
13085 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
13087 * w32fns.c (w32_default_color_map): New function,
13088 extracted from Fw32_default_color_map.
13089 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
13091 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
13093 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
13095 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
13097 * keyboard.c (test_undefined): New function (bug#9751).
13098 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
13100 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
13102 * sysdep.c (init_sys_modes): Fix the check for the controlling
13103 terminal (Bug#6649).
13105 2011-10-20 Eli Zaretskii <eliz@gnu.org>
13107 * dispextern.h (struct bidi_it): New member next_en_type.
13109 * bidi.c (bidi_line_init): Initialize the next_en_type member.
13110 (bidi_resolve_explicit_1): When next_en_pos is valid for the
13111 current character, check also for next_en_type being WEAK_EN.
13112 (bidi_resolve_weak): Don't enter the expensive loop if the current
13113 position is before next_en_pos. Record the bidi type of the first
13114 non-ET, non-BN character we find, in addition to its position.
13115 (bidi_level_of_next_char): Invalidate next_en_type when
13116 next_en_pos is over-stepped.
13118 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
13120 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
13121 * editfns.c: Rewrite current-time-zone so that it invokes
13122 the equivalent of (format-time-string "%Z") to get the time zone name.
13123 This fixes a bug when the time zone name contains characters that
13124 need converting from the system time locale to Emacs internal format.
13125 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
13126 that patch fixed format-time-string to do the conversion, but
13127 I forgot to fix current-time-zone.
13128 (format_time_string): New function, containing most of
13129 what Fformat_time_string used to contain.
13130 (Fformat_time_string): Rewrite in terms of format_time_string.
13131 This doesn't change this function's behavior.
13132 (current-time-zone): Rewrite to use format_time_string.
13133 This fixes the bug reported by Michael Schierl in
13134 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
13135 Jason Rumney's 2007-06-07 change worked around this bug, but
13137 * systime.h (tzname, timezone): Remove no-longer-used declarations.
13139 2011-10-19 Eli Zaretskii <eliz@gnu.org>
13141 * xdisp.c (start_display): If the character at POS is displayed
13142 via a display vector, reset IT->current.dpvec_index to zero.
13143 (try_window_reusing_current_matrix): If a line ends in a display
13144 vector or the next line starts in a display vector, continue
13145 redrawing the window even though the character position of
13146 start_row was reached.
13149 2011-10-18 Chong Yidong <cyd@gnu.org>
13151 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
13152 with nobreak-char-display too.
13154 2011-10-18 Eli Zaretskii <eliz@gnu.org>
13156 Fix part 3 of bug#9771.
13157 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
13158 (bidi_resolve_neutral): Don't enter the expensive loop looking for
13159 non-neutral characters if the current character is a paragraph
13160 separator (a.k.a. Newline). This avoids running the same
13161 expensive loop twice, once when we consume the preceding newline
13162 and the other time when the line actually needs to be displayed.
13163 Avoid the loop when we see neutrals on the base embedding level
13164 following a character whose directionality is the same as the
13165 paragraph's. This avoids running the expensive loop when a line
13166 ends in a long sequence of neutrals, like control characters.
13167 Add assertion against STRONG_AL type. Slightly rearrange code
13168 that determines the type of a neutral given the first non-neutral
13170 (bidi_level_of_next_char): Set next_en_pos to zero when
13171 invalidating its info.
13173 2011-10-17 Eli Zaretskii <eliz@gnu.org>
13175 * xdisp.c (push_display_prop): Determine whether to record string
13176 or buffer position by IT->string, not by IT->method. Allow
13177 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
13178 (move_it_vertically_backward): Don't look for character position
13179 immediately after the newline when in a continuation line.
13182 2011-10-15 Martin Rudalics <rudalics@gmx.at>
13184 * window.c (coordinates_in_window): Rewrite and delabelize
13185 vertical border check. (Bug#5357) (Bug#9618)
13187 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
13189 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
13190 errors in XSetWindowBorder (bug#9310).
13192 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
13194 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
13195 avoid crash when xmalloc overrun checking is enabled.
13197 2011-10-13 Eli Zaretskii <eliz@gnu.org>
13199 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
13200 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
13201 cursor motion with <left> and <right> arrow keys.
13203 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
13204 some callers set that themselves.
13206 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13208 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
13209 display string and the previous row comes from the same string and
13210 is empty. (Bug#9739) (Bug#9738)
13212 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
13214 * doc.c (get_doc_string): Encode file name (bug#9735).
13216 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13218 * bidi.c (bidi_level_of_next_char):
13219 * xdisp.c (get_visually_first_element): Remove old incorrect
13220 comments regarding the Unicode Line Separator character.
13222 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
13224 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
13226 * alloc.c (Fgc_status): Do not access beyond zombies array
13227 boundary if nzombies > MAX_ZOMBIES.
13228 * alloc.c (dump_zombies): Add missing format specifier.
13230 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
13232 * xdisp.c (set_cursor_from_row): Simplify conditionals,
13233 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
13235 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
13236 Some packages use them to denote characters with modifiers.
13238 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
13240 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
13241 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
13242 matching a pp-number. Rename parameter var to var1.
13244 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
13246 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
13248 2011-10-08 Glenn Morris <rgm@gnu.org>
13250 * callint.c (Fcall_interactively): Give a more explicit error for the
13251 'c' case with a non-character input. (Bug#8479)
13253 2011-10-08 Eli Zaretskii <eliz@gnu.org>
13255 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
13257 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
13258 lines that are hscrolled on the left.
13260 * dispnew.c (buffer_posn_from_coords): Account for a possible
13261 presence of header-line. (Bug#4426)
13263 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
13265 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
13266 Don't advertise functionality which we discourage or doesn't work.
13268 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
13270 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
13271 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
13272 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
13273 this makes Emacs dump core during garbage collection on rare
13274 occasions. sizeof is obviously inferior to offsetof here, so
13275 stick with offsetof.
13276 (GC_POINTER_ALIGNMENT): New macro.
13277 (mark_memory): Omit 3rd (offset) arg; caller changed.
13278 Don't assume EMACS_INT alignment is the same as pointer alignment.
13280 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
13282 * keyboard.c (read_key_sequence_remapped): New var.
13283 (read_key_sequence): Compute remapping in the right buffer.
13284 (command_loop_1): Use read_key_sequence's remapping directly.
13286 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
13288 * dired.c (file_name_completion): Don't expand file name.
13289 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
13290 before checking file name handler.
13292 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
13293 they've been requested explicitly (bug#9591).
13295 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
13297 * keymap.c (Fsingle_key_description): Use make_specified_string
13298 instead of build_string to build string from push_key_description.
13301 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13303 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
13304 This fixes a Y2038 bug on 64-bit hosts.
13305 * buffer.c (reset_buffer):
13306 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
13307 (Fclear_buffer_auto_save_failure):
13308 Use 0, not -1, to represent an unset failure time, since time_t
13309 might not be signed.
13311 Remove dependency on glibc malloc internals.
13312 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13313 Move back here from lisp.h, but with their new implementations.
13314 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13315 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
13316 * charset.c (charset_table_init): New static var.
13317 (syms_of_charset): Use it instead of xmalloc. This removes a
13318 dependency on glibc malloc internals. See Eli Zaretskii's comment in
13319 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
13320 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13321 Move back to alloc.c.
13322 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13323 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
13325 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
13327 * nsterm.m (windowDidResize): Call x_set_window_size only when
13328 ns_in_resize is true. Otherwise set pixelwidth/height and
13329 call change_frame_size (Bug#9628).
13331 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13333 Port --enable-checking=all to Fedora 14 x86-64.
13334 * charset.c (syms_of_charset): Also account for glibc malloc's
13335 internal overhead when calculating the initial malloc maximum.
13337 Port --enable-checking=all to Fedora 14 x86.
13338 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13340 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
13341 (overrun_check_realloc, overrun_check_free):
13342 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
13343 That way, xmalloc returns a properly-aligned pointer even if
13344 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
13345 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
13346 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
13347 into account when calculating the initial malloc maximum.
13348 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13349 Move here from alloc.c, so that charset.c can use it too.
13350 Properly align; the old code wasn't right for common 32-bit hosts
13351 when configured with --enable-checking=all.
13352 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13353 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
13355 2011-09-29 Eli Zaretskii <eliz@gnu.org>
13357 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
13360 2011-09-28 Eli Zaretskii <eliz@gnu.org>
13362 * xdisp.c (compute_display_string_end): If there's no display
13363 string at CHARPOS, return -1.
13365 * bidi.c (bidi_fetch_char): When compute_display_string_end
13366 returns a negative value, treat the character as a normal
13367 character not covered by a display string. (Bug#9624)
13369 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
13371 * lread.c (Fread_from_string): Fix typo in docstring.
13373 2011-09-27 Eli Zaretskii <eliz@gnu.org>
13375 * xdisp.c (handle_invisible_prop): If invisible text ends on a
13376 newline, reseat the iterator instead of bidi-iterating there one
13377 character at a time. (Bug#9610)
13378 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
13379 TO_CHARPOS if the bidi iterator is at base embedding level.
13381 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
13383 * lread.c (readevalloop): Use correct code for NBSP.
13384 (read1): Likewise. (Bug#9608)
13386 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
13388 * dbusbind.c (Fdbus_register_signal): When service is not
13389 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
13391 2011-09-25 Glenn Morris <rgm@gnu.org>
13393 * buffer.c (truncate-lines): Doc fix.
13395 2011-09-24 Chong Yidong <cyd@stupidchicken.com>

13410 2011-09-24 Eli Zaretskii <eliz@gnu.org>
13412 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
13413 Default value is now t. Doc fix.
13415 * indent.c (Fvertical_motion): Compute and apply the overshoot
13416 logic when moving up, not only when moving down. Fix the
13417 confusing name and values of the it_overshoot_expected variable;
13418 logic changes accordingly. (Bug#9254) (Bug#9549)
13420 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
13421 CHARPOS is covered by a display string which includes newlines.
13422 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
13423 is covered by a display string with embedded newlines.
13425 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
13427 * dbusbind.c (Fdbus_register_signal): Add match rule to
13428 Vdbus_registered_objects_table. (Bug#9581)
13429 (Fdbus_register_method, Vdbus_registered_objects_table):
13432 2011-09-24 Jim Meyering <meyering@redhat.com>
13434 do not ignore write error for any output size
13435 The previous change was incomplete.
13436 While it makes emacs --batch detect the vast majority of stdout
13437 write failures, errors were still ignored whenever the output size is
13438 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
13439 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
13440 && echo FAIL: ignored write error
13441 FAIL: ignored write error
13442 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
13443 && echo FAIL: ignored write error
13444 FAIL: ignored write error
13445 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
13447 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
13449 * emacs.c (Fkill_emacs): In noninteractive mode exit
13450 non-successfully if a write error occurred on stdout. (Bug#9574)
13452 2011-09-21 Eli Zaretskii <eliz@gnu.org>
13454 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
13457 * dispextern.h (struct it): Update the comment documenting what
13460 2011-09-20 Eli Zaretskii <eliz@gnu.org>
13462 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
13463 a display string, extend search for cursor position to end of row.
13464 (find_row_edges): If the row ends in a newline from a display
13465 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
13466 Handle the case of a display string with multiple newlines.
13467 (Fcurrent_bidi_paragraph_direction): Fix search for previous
13468 non-empty line. Fixes confusing cursor motion with arrow keys at
13469 the beginning of a line that starts with whitespace.
13471 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
13473 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
13476 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
13478 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
13479 boolean (Bug#9154).
13481 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13483 * xdisp.c (display_line): Record maximum and minimum buffer
13484 positions even if no glyphs were produced (e.g., by a zero-width
13485 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
13486 buffer positions that will be removed from the glyph row because
13488 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
13489 column is beyond frame width: don't subtract 1 "pixel" when
13490 computing width of the stretch.
13491 (reseat_at_next_visible_line_start): Undo the change made on
13492 2011-09-17 that saved paragraph information and restored it after
13493 the call to `reseat'. (Bug#9545)
13495 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13497 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
13498 and turn window cursor on if cleared (Bug#9415).
13500 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
13502 * search.c (boyer_moore): Take unibyte characters from pattern
13503 literally. (Bug#9458)

13513 initialized, to pacify gcc -Wuninitialized.
13515 * fileio.c: Report proper errno when syscall falls.
13516 (Finsert_file_contents): Save and restore errno,
13517 so that report_file_error outputs the correct diagnostic.
13518 (Fwrite_region) [CLASH_DETECTION]: Likewise.
13520 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13522 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
13524 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13526 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
13527 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
13529 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13531 * xdisp.c (reseat_at_next_visible_line_start): Keep information
13532 about the current paragraph and restore it after the call to reseat.
13534 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
13535 (bidi_find_paragraph_start): Search back for paragraph beginning
13536 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
13537 (bidi_move_to_visually_next): Only trigger paragraph-related
13538 computations when the last character is a newline or at EOB, not
13539 just any NEUTRAL_B. (Bug#9470)
13541 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
13542 truncated lines if point is covered by a display string. (Bug#9524)
13544 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
13546 * xselect.c: Relax test for outgoing X longs (Bug#9498).
13547 (cons_to_x_long): New function.
13548 (lisp_data_to_selection_data): Use it. Correct the test for
13549 short-versus-long data; it was negated. Break out of vector
13550 loop, for efficiency, when a long datum is discovered.
13552 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
13554 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
13556 2011-09-16 Eli Zaretskii <eliz@gnu.org>
13558 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
13559 GCC PR/17406) by declaring this function with external scope.
13561 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13563 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
13564 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
13566 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
13568 * editfns.c (Fformat): Correctly handle text properties on "%%".

13578 of TAB characters in a composition.
13580 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13582 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
13583 This occurs when processing a multibyte format.
13584 Problem reported by Wolfgang Jenker.
13586 2011-09-15 Johan Bockgård <bojohan@gnu.org>
13588 * xdisp.c (try_cursor_movement): Only check for exact match if
13589 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
13591 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13593 Remove unused external symbols.
13594 * dispextern.h (calc_pixel_width_or_height): Remove decl.
13595 * xdisp.c (calc_pixel_width_or_height): Now static.
13596 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.

13601 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13603 * xselect.c: Use signed conversions more consistently (Bug#9498).
13604 (selection_data_to_lisp_data): Assume incoming selection data are
13605 signed integers, not unsigned. This is to be consistent with
13606 outgoing selection data, which was modified to use signed integers
13607 in as part of the fix to Bug#9196 in response to Jan D.'s comment
13608 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
13609 expects long, not unsigned long.
13611 2011-09-14 Eli Zaretskii <eliz@gnu.org>
13613 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
13614 computation of loop end. Reported by Johan Bockgård
13617 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
13619 * frame.c (Fother_visible_frames_p): Function deleted.
13621 2011-09-12 Eli Zaretskii <eliz@gnu.org>
13623 * indent.c (compute_motion): Process display vector front to back
13624 rather than the other way around. (Bug#2496)
13626 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
13628 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
13630 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
13632 * minibuf.c (Fread_from_minibuffer): Doc fix.
13634 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13636 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
13637 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
13639 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
13641 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
13642 value for non-existent files.
13644 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13646 * fileio.c (Finsert_file_contents): If the file cannot be opened,
13647 set its "size" to -1. This will set the modtime_size field of
13648 the corresponding buffer to -1, which is what
13649 verify-visited-file-modtime expects for files that do not exist.
13652 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
13654 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
13656 * lisp.h: ... from here. push_key_description is no longer
13657 defined in keyboard.c, so its declaration should not be in
13658 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
13659 logically belongs with push_key_description.
13661 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
13663 * buffer.h: Include <sys/types.h> instead of <time.h>.
13664 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
13665 Problem reported by Herbert J. Skuhra.
13667 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
13669 * xml.c (parse_region): Make the parsing work for
13670 non-comment-starting XML files again (bug#9144).
13672 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
13674 * image.c (gif_load): Fix calculation of bottom and right corner.
13677 2011-09-10 Eli Zaretskii <eliz@gnu.org>
13679 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
13680 redisplay in small windows.
13682 2011-09-09 Eli Zaretskii <eliz@gnu.org>
13684 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
13686 2011-09-08 Martin Rudalics <rudalics@gmx.at>
13688 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
13689 Operate on live windows only.
13691 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
13693 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
13695 2011-09-07 Eli Zaretskii <eliz@gnu.org>
13697 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
13698 only under bidi iteration.
13700 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
13702 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
13704 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13706 isnan: Fix porting problem to Solaris 10 with bundled gcc.
13707 Without this fix, the command to link temacs failed due to an
13708 undefined symbol __builtin_isnan. This is because
13709 /usr/include/iso/math_c99.h #defines isnan(x) to
13710 __builtin_isnan(x), but the bundled gcc, which identifies itself
13711 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
13713 * floatfns.c (isnan): #undef, and then #define to a clone of
13715 (Fisnan): Always define, since it's always available now.
13716 (syms_of_floatfns): Always define isnan at the Lisp level.
13718 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13720 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
13722 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13724 * fileio.c: Fix bugs with large file offsets (Bug#9428).
13725 The previous code assumed that file offsets (off_t values) fit in
13726 EMACS_INT variables, which is not true on typical 32-bit hosts.
13727 The code messed up by falsely reporting buffer overflow in cases
13728 such as (insert-file-contents "big" nil 1 2) into an empty buffer
13729 when "big" contains more than 2**29 bytes, even though this
13730 inserts just one byte and does not overflow the buffer.
13731 (Finsert_file_contents): Store file offsets as off_t
13732 values, not as EMACS_INT values. Check for overflow when
13733 converting between EMACS_INT and off_t. When checking for
13734 buffer overflow or for overlap, take the offsets into account.
13735 Don't use EMACS_INT for small values where int suffices.
13736 When checking for overlap, fix a typo: ZV was used where
13737 ZV_BYTE was intended.
13738 (Fwrite_region): Don't assume off_t fits into 'long'.
13739 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
13741 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
13743 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
13745 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13747 sprintf-related integer and memory overflow issues (Bug#9412).
13749 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
13750 (esprintf, exprintf, evxprintf): New functions.
13751 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
13752 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
13753 (modify_event_symbol): Do not assume that the length of
13754 name_alist_or_stem is safe to alloca and fits in int.
13755 (Fexecute_extended_command): Likewise for function name and binding.
13756 (Frecursion_depth): Wrap around reliably on integer overflow.
13757 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
13758 since some callers pass EMACS_INT values.
13759 (Fsingle_key_description): Don't crash if symbol name contains more
13760 than MAX_ALLOCA bytes.
13761 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
13762 (get_minibuffer): Arg is now EMACS_INT, not int.
13763 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
13764 (esprintf, exprintf, evxprintf): New decls.
13765 * window.h (command_loop_level, minibuf_level): Reflect API changes.
13767 * dbusbind.c (signature_cat): New function.
13768 (xd_signature, Fdbus_register_signal):
13769 Do not overrun buffer; instead, report string overflow.
13771 * dispnew.c (add_window_display_history): Don't overrun buffer.
13772 Truncate instead; this is OK since it's just a log.
13774 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
13775 even if the time zone offset is outlandishly large.
13776 Don't mishandle offset == INT_MIN.
13778 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
13779 when creating daemon; the previous buffer-overflow check was incorrect.
13781 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
13782 which has the guts of the old verror function.
13784 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
13785 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
13787 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
13788 (font_unparse_xlfd): Don't blindly alloca long strings.
13789 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
13790 fits in int, when using sprintf. Use single snprintf to count
13791 length of string rather than counting it via multiple sprintfs;
13792 that's simpler and more reliable.
13793 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
13794 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
13795 sprintf, in case result does not fit in int.
13797 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
13798 (fontset_from_font): Print it.
13800 * frame.c (tty_frame_count): Now printmax_t, not int.
13801 (make_terminal_frame, set_term_frame_name): Print it.
13802 (x_report_frame_params): In X, window IDs are unsigned long,
13803 not signed long, so print them as unsigned.
13804 (validate_x_resource_name): Check for implausibly long names,
13805 and don't assume name length fits in 'int'.
13806 (x_get_resource_string): Don't blindly alloca invocation name;
13807 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
13810 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
13811 (xg_check_special_colors, xg_set_geometry):
13812 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
13814 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
13815 Use esprintf, not sprintf, in case result does not fit in int.
13817 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13818 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
13819 it as a large positive number.
13820 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
13821 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13823 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
13824 in case result does not fit in int.
13826 * print.c (float_to_string): Detect width overflow more reliably.
13827 (print_object): Make sprintf buffer a bit bigger, to avoid potential
13828 buffer overrun. Don't assume list length fits in 'int'. Treat
13829 print length of 0 as 0, not as infinity; to be consistent with other
13830 uses of print length in this function. Don't overflow print length
13831 index. Don't assume hash table size fits in 'long', or that
13832 vectorlike size fits in 'unsigned long'.
13834 * process.c (make_process): Use printmax_t, not int, to format
13835 process-name gensyms.
13837 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
13839 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
13840 to avoid potential buffer overrun.
13842 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
13843 if X resource line is longer than 512 bytes.
13845 * xfns.c (x_window): Make sprintf buffer a bit bigger
13846 to avoid potential buffer overrun.
13848 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
13850 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
13852 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13854 Integer overflow fixes for scrolling, etc.
13855 Without these, Emacs silently mishandles large integers sometimes.
13856 For example, "C-u 4294967297 M-x recenter" was treated as if
13857 it were "C-u 1 M-x recenter" on a typical 64-bit host.
13859 * xdisp.c (try_window_id): Check Emacs fixnum range before
13860 converting to 'int'.
13862 * window.c (window_scroll_line_based, Frecenter):
13863 Check that an Emacs fixnum is in range before assigning it to 'int'.
13864 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
13865 values converted from Emacs fixnums.
13866 (Frecenter): Don't wrap around a line count if it is out of 'int'
13867 range; instead, treat it as an extreme value.
13868 (Fset_window_configuration, compare_window_configurations):
13869 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
13871 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
13872 that can exceed INT_MAX. Check that EMACS_INT value is in range
13873 before assigning it to the (possibly-narrower) index.
13874 (match_limit): Don't assume that a fixnum can fit in 'int'.
13876 * print.c (print_object): Use ptrdiff_t, not int, for index that can
13879 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
13880 (Fvertical_motion): Don't wrap around LINES values that don't fit
13881 in 'int'. Instead, treat them as extreme values. This is good
13882 enough for windows, which can't have more than INT_MAX lines anyway.
13884 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
13886 * Require libxml/parser.h to avoid compilation warning.
13888 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
13890 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
13891 since this reportedly can destroy thread storage.
13893 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
13895 * syntax.c (find_defun_start): Update all cache variables if
13896 exiting early (Bug#9401).
13898 2011-08-30 Eli Zaretskii <eliz@gnu.org>
13900 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
13902 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
13903 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
13904 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
13906 * term.c (tty_append_glyph): New function.
13907 (produce_stretch_glyph): Static function and its prototype deleted.
13909 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
13912 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
13914 * image.c (parse_image_spec): Check for nonnegative, not for positive,
13915 when checking :margin (Bug#9390).
13916 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
13917 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
13918 so that the name doesn't mislead. All uses changed.
13920 2011-08-28 Johan Bockgård <bojohan@gnu.org>
13922 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
13925 2011-08-27 Eli Zaretskii <eliz@gnu.org>
13927 * xdisp.c (move_it_to): Don't bail out early when reaching
13928 position beyond to_charpos, if we are scanning backwards.
13929 (move_it_vertically_backward): When DY == 0, make sure we get to
13930 the first character in the line after the newline.
13932 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
13934 * ccl.c: Improve and simplify overflow checking (Bug#9196).
13935 (ccl_driver): Do not generate an out-of-range pointer.
13936 (Fccl_execute_on_string): Remove unnecessary check for
13937 integer overflow, noted by Stefan Monnier in
13938 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
13939 Remove a FIXME that didn't need fixing.
13940 Simplify the newly-introduced buffer reallocation code.
13942 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
13944 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
13946 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
13948 Integer and memory overflow issues (Bug#9196).
13950 * doc.c (get_doc_string): Rework so that
13951 get_doc_string_buffer_size is the actual buffer size, rather than
13952 being 1 less than the actual buffer size; this makes xpalloc more
13955 * image.c (x_allocate_bitmap_record, cache_image):
13956 * xselect.c (Fx_register_dnd_atom):
13957 Simplify previous changes by using xpalloc.
13959 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
13960 since either will do and ptrdiff_t is convenient with xpalloc.
13962 * charset.c (charset_table_size)
13963 (struct charset_sort_data.priority): Now ptrdiff_t.
13964 (charset_compare): Don't overflow if priorities differ greatly.
13965 (Fsort_charsets): Don't assume list length fits in int.
13966 Check for size-calculation overflow when allocating sort data.
13967 (syms_of_charset): Allocate an initial charset table that is
13968 just under 64 KiB, to avoid problems with glibc malloc and mmap.
13970 * cmds.c (internal_self_insert): Check for size-calculation overflow.
13972 * composite.h (struct composition.glyph_len): Now int, not unsigned.
13973 The actual value is always <= INT_MAX, and leaving it unsigned made
13974 overflow checking harder.
13976 * dispextern.h (struct glyph_matrix.rows_allocated)
13977 (struct face_cache.size): Now ptrdiff_t, for convenience in use
13978 with xpalloc. The values are still always <= INT_MAX.
13980 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
13982 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
13983 (SAFE_NALLOCA): New macro.
13985 * region-cache.c (struct boundary.pos, find_cache_boundary)
13986 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
13987 (set_cache_region, invalidate_region_cache)
13988 (revalidate_region_cache, know_region_cache, region_cache_forward)
13989 (region_cache_backward, pp_cache):
13990 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
13991 so that ptrdiff_t * can be passed to xpalloc.
13992 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
13993 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
13994 (pp_cache): Don't assume cache_len fits in int.
13995 * region-cache.h: Adjust extern decls to match.
13997 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
13998 EMACS_INT, since either will do, for xpalloc.
14000 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
14001 (xnmalloc, xnrealloc, xpalloc): New functions.
14003 * bidi.c (bidi_shelve_header_size): New constant.
14004 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
14005 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
14007 * bidi.c (bidi_cache_shrink):
14008 * buffer.c (overlays_at, overlays_in, record_overlay_string)
14010 Don't update size of array until after memory allocation succeeds,
14011 because xmalloc/xrealloc may not return.
14012 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
14013 now that we have proper integer overflow checking.
14014 (record_overlay_string, overlay_strings): Catch overflows when
14015 calculating size of overlay_str_buf.
14017 * callproc.c (Fcall_process): Check for size overflow when
14018 calculating size of args2.
14019 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
14020 Normally we prefer signed values, but sticking with ptrdiff_t would
14021 require adding more-complicated checks.
14023 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
14024 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
14025 Redo buffer-overflow calculations to avoid integer overflow.
14026 Add a FIXME comment where memory seems to be over-allocated.
14028 * character.c (Fstring): Check for size-calculation overflow.
14030 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
14031 unnecessary integer overflow. Check for size overflow.
14032 (encode_coding_object): Don't update size until xmalloc succeeds.
14034 * composite.c (get_composition_id): Check for overflow in glyph
14035 length calculations.
14037 Integer and memory overflow fixes for display code.
14038 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
14039 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
14040 (scrolling_window): Check for overflow in size calculations.

14052 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
14053 (get_doc_string): Check for size calculation overflow.
14054 Don't update size until allocation succeeds.
14055 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
14056 EMACS_INT, where ptrdiff_t will do.
14057 (Fsubstitute_command_keys): Check for string overflow.
14059 * editfns.c (set_time_zone_rule): Don't assume environment length
14061 (message_length): Now ptrdiff_t, not int.
14062 (Fmessage_box): Don't update size until allocation succeeds.
14063 Don't assume message length fits in int.
14064 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
14066 * emacs.c (main): Do not reallocate argv, since there is a null at
14067 the end that can be overwritten, and this way there's no need to
14068 worry about size-calculation overflow.
14069 (sort_args): Check for size-calculation overflow.
14071 * eval.c (init_eval_once, grow_specpdl): Don't update size until
14073 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
14075 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
14076 (x_set_scroll_bar_width, x_figure_window_size):
14077 Check for integer overflow.
14078 (x_set_alpha): Do not assume XINT fits in int.
14080 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
14081 This is for the members text_lines, text_cols, total_lines, total_cols,
14082 where the system imposes an 'int' limit.
14084 * fringe.c (Fdefine_fringe_bitmap):
14085 Don't update size until alloc works.
14087 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
14088 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
14090 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
14091 Check for size-calculation overflow.
14092 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
14093 do, as we prefer signed integers.
14094 (id_to_widget.max_size, id_to_widget.used)
14095 (xg_store_widget_in_map, xg_remove_widget_from_map)
14096 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
14097 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
14098 Use and return ptrdiff_t, not int.
14099 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
14100 * gtkutil.h: Change prototypes to match the above.
14102 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
14103 are duplicate now that they've been promoted to lisp.h.
14104 (x_allocate_bitmap_record, x_alloc_image_color)
14105 (make_image_cache, cache_image, xpm_load):
14106 Don't update size until alloc is done.
14107 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)

14110 (ct_colors_allocated_max): New constant.
14111 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid

14117 Use ptrdiff_t, not int, to count maps.
14118 (read_char_minibuf_menu_prompt): Check for overflow in size
14119 calculations. Don't update size until allocation succeeds.
14120 Redo calculations to avoid overflow.
14121 * keyboard.h: Change prototypes to match the above.
14123 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
14125 (current_minor_maps): Check for size calculation overflow.
14126 * keymap.h: Change prototypes to match the above.
14128 * lread.c (read1, init_obarray): Don't update size until alloc done.
14130 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.

14133 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
14134 Now ptrdiff_t, not int.
14135 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

14147 (Fset_match_data): Don't assume list lengths fit in 'int'.
14149 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
14150 for command line length. Do not attempt to address one before the
14151 beginning of an array, as that's not portable.
14153 * term.c (max_frame_lines): Remove; unused.
14154 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
14156 (encode_terminal_code, calculate_costs): Check for size
14157 calculation overflow.

14160 done. Redo calculations to avoid overflow.
14161 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
14163 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
14164 subtracting pointers.
14165 (gobble_line): Check for overflow more carefully. Don't update size
14168 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.

14179 Use ptrdiff_t, not int, for sizes.
14180 (Finternal_make_lisp_face, cache_face):
14181 Check for size calculation overflow.
14182 (cache_face): Treat size calculation overflows as if they were
14183 memory exhaustion (the usual treatment), rather than aborting.
14185 * xfns.c (x_encode_text, x_set_name_internal)
14186 (Fx_change_window_property): Use ptrdiff_t, not int, to count
14187 sizes, since they can exceed INT_MAX in size. Check for size
14188 calculation overflow.
14190 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
14191 (xg_select): Check for size calculation overflow.
14192 Don't update size until alloc done.
14194 * xrdb.c (get_environ_db): Don't assume path length fits in int,
14195 as sprintf is limited to int lengths.
14197 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
14198 (X_LONG_MIN): New macros.
14199 Use them to make the following changes clearer.
14200 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
14201 This change doesn't affect the value now, but it may help remind
14202 future maintainers not to raise the value too much later.
14203 (SELECTION_QUANTUM): Remove, replacing with ...
14204 (selection_quantum): ... new function, which avoids overflow.
14206 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
14207 assumption that selection length fits in 'int'.

14219 (x_get_window_property, receive_incremental_selection)
14220 (lisp_data_to_selection_data, x_property_data_to_lisp):
14221 Check for size-calculation overflow.
14222 (x_get_window_property, receive_incremental_selection)
14223 (lisp_data_to_selection_data, Fx_register_dnd_atom):
14224 Don't store size until memory allocation succeeds.
14225 (x_get_window_property): Plug memory leak on memory exhaustion.
14226 Don't double-block input; malloc is safe here. Don't assume 2**34
14227 - 4 fits in unsigned long. Add an xassert to check
14228 XGetWindowProperty overflow. Be more careful about overflow
14229 calculations, and distinguish size from memory overflow better.
14230 (receive_incremental_selection): When tracing, don't assume
14231 unsigned int is less than INT_MAX.
14232 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
14233 harmful) conversions of unsigned short to int.
14234 (lisp_data_to_selection_data): Don't assume that integers
14235 in the range -65535 through -1 fit in an X unsigned short.
14236 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
14237 result parameters unless successful. Rely on cons_to_unsigned
14238 to report problems with elements; the old code wasn't right anyway.
14239 (x_check_property_data): Check for int overflow; we cannot use
14240 a wider type due to X limits.
14241 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
14243 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.

14273 * lisp.h (hash_lookup, hash_put):
14274 * minibuf.c (Ftest_completion):
14275 Use ptrdiff_t for hash table indexes, not int (which is too
14276 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
14277 32-bit --with-wide-int hosts).
14279 * charset.c (Fdefine_charset_internal): Check for integer overflow.
14280 Add a FIXME comment about memory leaks.
14281 (syms_of_charset): Don't assume xmalloc returns.
14283 Don't assume that stated character widths fit in int.

14288 with outlandish widths.
14289 * character.h (sanitize_tab_width): Rename from sanitize_width,
14290 now that we have two such functions. All uses changed.
14291 (sanitize_char_width): New inline function.
14293 Don't assume that tab-width fits in int.
14294 * character.h (sanitize_width): New inline function.
14295 (SANE_TAB_WIDTH): New macro.
14296 (ASCII_CHAR_WIDTH): Use it.

14301 * fileio.c: Integer overflow issues with file modes.
14302 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
14304 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
14305 Remove unreachable code.
14306 (read_hex, load_charset_map_from_file): Check for integer overflow.
14308 * xterm.c: Don't go over XClientMessageEvent limit.
14309 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
14310 (x_send_scroll_bar_event): Likewise. Check that the size does not
14311 exceed limits imposed by XClientMessageEvent, as well as the usual
14312 ptrdiff_t and size_t limits.
14314 * keyboard.c: Overflow, signedness and related fixes.
14315 (make_lispy_movement): Use same integer type in forward decl
14316 that is used in the definition.
14317 (read_key_sequence, keyremap_step):
14318 Change bufsize argument back to int, undoing my 2011-03-30 change.
14319 We prefer signed types, and int is wide enough here.
14320 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
14321 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
14322 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
14323 length, not size_t. Use ptrdiff_t for index, not int.
14324 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
14325 possibility of integer overflow.
14327 Overflow, signedness and related fixes for images.
14329 * dispextern.h (struct it.stack[0].u.image.image_id)
14330 (struct_it.image_id, struct image.id, struct image_cache.size)

14346 when the callers expect that.
14347 (image_ascent): Redo ascent calculation to avoid int overflow.
14348 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
14349 (lookup_image): Remove unnecessary tests.
14350 (xbm_image_p): Locals are now of int, not EMACS_INT,
14351 since parse_image_check makes sure they fit into int.
14352 (png_load, gif_load, svg_load_image):
14353 Prefer int to unsigned where either will do.
14354 (tiff_handler): New function, combining the cores of the
14355 old tiff_error_handler and tiff_warning_handler.
14356 This function is rewritten to use vsnprintf and thereby avoid
14357 stack buffer overflows. It uses only the features of vsnprintf
14358 that are common to both POSIX and native Microsoft.
14359 (tiff_error_handler, tiff_warning_handler): Use it.
14360 (tiff_load, gif_load, imagemagick_load_image):
14361 Don't assume :index value fits in 'int'.
14362 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
14363 (imagemagick_load_image): Check that crop parameters fit into
14364 the integer types that MagickCropImage accepts. Don't assume
14365 Vimagemagick_render_type has a nonnegative value. Don't assume
14366 size_t fits in 'long'.
14367 (gs_load): Use printmax_t to print the widest integers possible.
14368 Check for integer overflow when computing image height and width.

14380 handle_single_display_spec, not just 1 or zero.
14381 (handle_single_display_spec): If the display spec is of the form
14382 `(space ...)', and specifies display in the text area, return 2
14384 (try_cursor_movement): Check for the need to scroll more
14385 accurately, and prefer exact match for point under bidi.
14386 Don't advance `row' beyond the last row of the window.
14388 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
14389 into disp_prop; all users changed.
14391 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
14392 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
14393 for the text covered by the display property.

14403 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
14404 buffers, return left-to-right.
14405 (set_cursor_from_row): Consider candidate row a win if its glyph
14406 represents a newline and point is on that newline. Fixes cursor
14407 positioning on the newline at EOL of R2L text within L2R
14408 paragraph, and vice versa.
14409 (try_cursor_movement): Check continued rows, in addition to
14410 continuation rows. Fixes unwarranted scroll when point enters a
14411 continued line of R2L text within an L2R paragraph, or vice versa.
14412 (cursor_row_p): Consider the case of point being equal to
14413 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
14414 from the end of a short line to the beginning of a continued line
14415 of R2L text within L2R paragraph.
14416 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
14417 composed characters.
14419 * bidi.c (bidi_check_type): Use xassert.
14420 (bidi_cache_iterator_state): Update the disp_pos and disp_prop_p
14423 2011-08-23 Eli Zaretskii <eliz@gnu.org>

14430 * nsfont.m (ns_otf_to_script): Fix typo.
14432 2011-08-22 Kenichi Handa <handa@m17n.org>
14434 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
14435 extra slot even if the purpose is char-code-property-table.
14437 2011-08-23 Eli Zaretskii <eliz@gnu.org>
14439 * xdisp.c (redisplay_window): When computing centering_position,
14440 account for the height of the header line. (Bug#8874)
14442 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
14443 instead of CHAR_TO_BYTE. Fixes a crash when a completion
14444 candidate is selected by the mouse, and that candidate has a
14445 composed character under the mouse.
14447 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
14448 coordinates reported by pos-visible-in-window-p for a composed
14449 character in column zero.
14451 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
14453 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
14455 2011-08-22 Eli Zaretskii <eliz@gnu.org>
14457 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
14458 consider it a hit if to_charpos is anywhere in the range of the
14459 composed buffer positions.
14461 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
14463 * image.c (gif_load): Don't assume that each subimage has the same
14464 dimensions as the base image. Handle disposal method that is
14465 "undefined" by the gif spec (Bug#9335).
14467 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
14469 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

14472 2011-08-19 Eli Zaretskii <eliz@gnu.org>
14474 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
14475 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
14476 from an Org mode buffer to a Speedbar frame.
14478 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
14479 a composition, take its buffer position from IT->cmp_it.charpos.
14480 Fixes cursor positioning at the beginning of a line that begins
14481 with a composed character.
14483 2011-08-18 Eli Zaretskii <eliz@gnu.org>
14485 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
14486 character bidirectional type, use STRONG_L instead. Fixes crashes
14487 in a buffer produced by `describe-categories'.
14489 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
14490 members before the level stack, so they would be saved and
14491 restored when copying iterator state. Fixes incorrect reordering
14492 around TABs covered by display properties.
14494 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
14496 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

14566 * xdisp.c (move_it_in_display_line_to): Don't invoke
14567 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
14568 ppos_it. Fixes vertical cursor motion when line beginning is
14569 covered by an image. (Bug#9296)
14571 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
14573 * nsterm.h (ns_run_ascript): Declare.

14577 (ns_run_ascript): New function.
14578 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
14579 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
14580 the event loop. Get status from as_status (Bug#7276).
14582 * nsterm.m (sendEvent): If event is NSApplicationDefined and
14583 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
14584 the event loop (Bug#7276).
14586 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>

14610 (Fnetwork_interface_list): Allocate in increments of bytes instead
14611 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
14612 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
14614 (struct ifflag_def): notrailers is smart on OSX.
14615 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
14616 Get hardware address with getifaddrs if available.
14618 2011-08-12 Eli Zaretskii <eliz@gnu.org>
14620 * xdisp.c (iterate_out_of_display_property): xassert that
14621 IT->position is set to within IT->object's boundaries. Break from
14622 the loop as soon as EOB is reached; avoids infloops in redisplay

14624 Set IT->current to match the bidi iterator unconditionally.
14625 (push_display_prop): Allow GET_FROM_STRING as IT->method on
14626 entry. Force push_it to save on the stack the current
14627 buffer/string position, to be restored by pop_it. Fix flags in
14628 the iterator structure wrt the object coming from a display
14629 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
14630 properties. (Bug#9284)
14632 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
14634 * fontset.c (fontset_get_font_group): Add proper type checks.

14662 restore_point_unwind (Bug#5984).
14664 2011-08-07 Juri Linkov <juri@jurta.org>
14666 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'

14671 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
14672 display property strides EOL and includes a newline, as in
14673 longlines-mode. (Bug#9254)
14674 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
14675 word-wrap under bidirectional display. (Bug#9224)
14677 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
14678 is non-zero, even if the data buffer is NULL. Fixes a crash in
14679 vertical-motion with longlines-mode. (Bug#9254)
14681 2011-08-05 Eli Zaretskii <eliz@gnu.org>
14683 * bidi.c <bidi_cache_total_alloc>: Now static.

14686 * xdisp.c (display_line): Release buffer allocated for shelved bidi
14689 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
14690 amount allocated this far in `bidi_cache_total_alloc'.
14691 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
14692 non-zero, only free the data buffer without restoring the cache
14693 contents. All callers changed.
14695 * dispextern.h (bidi_unshelve_cache): Update prototype.
14697 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
14698 (move_it_in_display_line, move_it_to)
14699 (move_it_vertically_backward, move_it_by_lines): Replace the call
14700 to xfree to an equivalent call to bidi_unshelve_cache.
14701 (move_it_in_display_line_to): Fix logic of returning
14702 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
14704 2011-08-05 Eli Zaretskii <eliz@gnu.org>
14706 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that

14746 Fix slow cursor motion and scrolling in large buffers with
14747 selective display, like Org Mode buffers. (Bug#9218)
14749 * dispextern.h (struct bidi_it): New member disp_prop_p.
14751 * xdisp.c: Remove one-slot cache of display string positions.
14752 (compute_display_string_pos): Accept an additional argument
14753 DISP_PROP_P; callers changed. Scan at most 5K characters forward
14754 for a display string or property. If found, set DISP_PROP_P
14757 * bidi.c (bidi_fetch_char): Accept an additional argument
14758 DISP_PROP_P, and pass it to compute_display_string_pos.
14759 Only handle text covered by a display string if DISP_PROP_P is returned
14760 non-zero. All callers of bidi_fetch_char changed.
14762 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
14764 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
14766 2010-12-03 Don March <don@ohspite.net>
14768 * keymap.c (Fdefine_key): Fix non-prefix key error message when
14769 last character M-[char] is translated to ESC [char] (bug#7541).
14771 2011-08-02 Kenichi Handa <handa@m17n.org>
14773 * lisp.h (uniprop_table): Extern it.
14775 * chartab.c (uniprop_table): Make it non-static.
14777 2011-08-01 Eli Zaretskii <eliz@gnu.org>
14779 * xdisp.c (forward_to_next_line_start): Accept additional argument
14780 BIDI_IT_PREV, and store into it the state of the bidi iterator had
14782 (reseat_at_next_visible_line_start): Use the bidi iterator state
14783 returned by forward_to_next_line_start to restore the state of
14784 it->bidi_it after backing up to previous newline. (Bug#9212)
14786 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
14788 * regex.c (re_comp): Protoize.
14789 (re_exec): Fix return type.
14790 (regexec): Fix type of `ret'. (Bug#9203)
14792 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14794 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
14795 This is needed if max-image-size is a floating-point number.
14797 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
14799 * print.c (print_object): Print empty symbol as ##.
14801 * lread.c (read1): Read ## as empty symbol.
14803 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
14805 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
14806 setting frame foreground color (Bug#9175).
14807 (x_set_background_color): Likewise.
14809 * nsmenu.m (-setText): Size tooltip dimensions precisely to
14810 contents (Bug#9176).
14811 (EmacsTooltip -init): Remove bezels and add shadows to
14814 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
14815 or scroll bar (Bug#8470).
14817 * nsfont.m (nsfont_open): Remove assignment to voffset and
14818 unnecessary vars hshink, expand, hd, full_height, min_height.
14819 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
14821 * nsterm.h (nsfont_info): Remove voffset field.
14823 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
14825 Implement strike-through and overline on NextStep (Bug#8863).
14827 * nsfont.m (nsfont_open): Use underline position provided by font,
14828 instead of hard-coded value of 2.
14829 (nsfont_draw): Call ns_draw_text_decoration instead.
14831 * nsterm.h: Add declaration for ns_draw_text_decoration.
14833 * nsterm.m (ns_draw_text_decoration): New function for drawing
14834 underline, overline, and strike-through.
14835 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
14836 ns_draw_text_decoration. Change treatment of cursor drawing to
14837 accommodate underlining, etc.
14839 2011-07-28 Eli Zaretskii <eliz@gnu.org>
14841 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
14844 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14846 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
14847 Without this fix, if a signal arrives just after memory fills up,
14848 'malloc' might be invoked reentrantly.
14850 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
14851 In other words, assume that every image size is allowed, on non-X
14852 hosts. This assumption is probably wrong, but it lets Emacs compile.
14854 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
14856 * regex.c (re_iswctype): Convert return values to boolean.
14858 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
14860 * xdisp.c (compute_display_string_pos): Don't use cached display
14861 string position if the buffer had its restriction changed.
14864 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14866 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
14868 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14870 Integer signedness and overflow and related fixes. (Bug#9079)
14872 * bidi.c: Integer size and overflow fixes.
14873 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
14874 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
14875 (bidi_cache_find_level_change, bidi_cache_ensure_space)
14876 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
14877 (bidi_find_other_level_edge):
14878 Use ptrdiff_t instead of EMACS_INT where either will do.
14879 This works better on 32-bit hosts configured --with-wide-int.
14880 (bidi_cache_ensure_space): Check for size-calculation overflow.
14881 Use % rather than repeated addition, for better worst-case speed.
14882 Don't set bidi_cache_size until after xrealloc returns, because it
14884 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
14885 (bidi_cache_ensure_space): Also check that the bidi cache size
14886 does not exceed that of the largest Lisp string or buffer. See Eli
14887 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
14889 * alloc.c (__malloc_size_t): Remove.
14890 All uses replaced by size_t. See Andreas Schwab's note
14891 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
14893 * image.c: Improve checking for integer overflow.
14894 (check_image_size): Assume that f is nonnull, since
14895 it is always nonnull in practice. This is one less thing to
14896 worry about when checking for integer overflow later.
14897 (x_check_image_size): New function, which checks for integer
14898 overflow issues inside X.
14899 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
14900 This removes the need for a memory_full check.
14901 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
14902 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
14903 (xbm_read_bitmap_data): Change locals back to 'int', since
14904 their values must fit in 'int'.
14905 (xpm_load_image, png_load, tiff_load):
14906 Invoke x_create_x_image_and_pixmap earlier,
14907 to avoid much needless work if the image is too large.
14908 (tiff_load): Treat overly large images as if
14909 x_create_x_image_and_pixmap failed, not as malloc failures.
14910 (gs_load): Use x_check_image_size.
14912 * gtkutil.c: Omit integer casts.
14913 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
14914 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
14916 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
14918 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
14919 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
14920 would wrongly return t on a 64-bit host.
14922 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
14923 The plain *_OVERFLOW macros run afoul of GCC bug 49705
14924 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
14925 and therefore cause GCC to emit a bogus diagnostic in some cases.
14927 * image.c: Integer signedness and overflow and related fixes.
14928 This is not an exhaustive set of fixes, but it's time to
14929 record what I've got.
14930 (lookup_pixel_color, check_image_size): Remove redundant decls.
14931 (check_image_size): Don't assume that arbitrary EMACS_INT values
14932 fit in 'int', or that arbitrary 'double' values fit in 'int'.
14933 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
14934 (tiff_load, imagemagick_load_image):
14935 Check for overflow in size calculations.
14936 (x_create_x_image_and_pixmap): Remove unnecessary test for
14937 xmalloc returning NULL; that can't happen.
14938 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
14939 (xpm_color_bucket): Use better integer hashing function.
14940 (xpm_cache_color): Don't possibly over-allocate memory.
14941 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
14942 (gif_memory_source):
14943 Use ptrdiff_t, not int or size_t, to record sizes.
14944 (png_load): Don't assume values greater than 2**31 fit in 'int'.
14945 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
14946 either works, as we prefer signed integers.
14947 (tiff_read_from_memory, tiff_write_from_memory):
14948 Return tsize_t, not size_t, since that's what the TIFF API wants.
14949 (tiff_read_from_memory): Don't fail simply because the read would
14950 go past EOF; instead, return a short read.
14951 (tiff_load): Omit no-longer-needed casts.
14952 (Fimagemagick_types): Don't assume size fits into 'int'.
14954 Improve hashing quality when configured --with-wide-int.
14955 * fns.c (hash_string): New function, taken from sxhash_string.
14956 Do not discard information about ASCII character case; this
14957 discarding is no longer needed.
14958 (sxhash-string): Use it. Change sig to match it. Caller changed.
14959 * lisp.h: Declare it.
14960 * lread.c (hash_string): Remove, since we now use fns.c's version.
14961 The fns.c version returns a wider integer if --with-wide-int is
14962 specified, so this should help the quality of the hashing a bit.
14964 * emacs.c: Integer overflow minor fix.
14965 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
14966 Define only if GNU_LINUX.
14967 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
14969 * dispnew.c: Integer signedness and overflow fixes.
14970 Remove unnecessary forward decls, that were a maintenance hassle.
14971 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
14973 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
14974 (scrolling_window): Use ptrdiff_t, not int, for byte count.
14975 (prepare_desired_row, line_draw_cost):
14976 Use int, not unsigned, where either works.
14977 (save_current_matrix, restore_current_matrix):
14978 Use ptrdiff_t, not size_t, where either works.
14979 (init_display): Check for overflow more accurately, and without
14980 relying on undefined behavior.
14982 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
14983 Remove, replacing with the new symbols in lisp.h. All uses changed.
14984 * fileio.c (make_temp_name):
14985 * filelock.c (lock_file_1, lock_file):
14986 * xdisp.c (message_dolog):
14987 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
14988 Use pMd etc. instead.
14989 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
14990 replacing the pWIDE etc. symbols removed from editfns.c.
14992 * keyboard.h (num_input_events): Now uintmax_t.
14993 This is (very slightly) less likely to mess up due to wraparound.
14996 * buffer.c: Integer signedness fixes.
14997 (alloc_buffer_text, enlarge_buffer_text):
14998 Use ptrdiff_t rather than size_t when either will do, as we prefer
15001 * alloc.c: Integer signedness and overflow fixes.
15002 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
15003 (__malloc_size_t): Default to size_t, not to int.
15004 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
15005 (Fgarbage_collect, mark_object_loop_halt, mark_object):
15006 Prefer ptrdiff_t to size_t when either would do, as we prefer
15008 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
15009 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
15010 Now const. Initialize with values that are in range even if char
15012 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
15013 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
15014 These functions do the right thing with sizes > 2**32.
15015 (check_depth): Now ptrdiff_t, not int.
15016 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
15017 Adjust to new way of storing sizes. Check for size overflow bugs
15019 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
15020 slightly wrong anyway, as it missed one instance of
15021 XMALLOC_OVERRUN_CHECK_OVERHEAD.
15022 (refill_memory_reserve): Omit needless cast to size_t.
15023 (mark_object_loop_halt): Mark as externally visible.
15025 * xselect.c: Integer signedness and overflow fixes.
15026 (Fx_register_dnd_atom, x_handle_dnd_message):
15027 Use ptrdiff_t, not size_t, since we prefer signed.
15028 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
15029 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
15030 x_dnd_atoms_size and x_dnd_atoms_length.
15032 * doprnt.c: Prefer signed to unsigned when either works.
15034 * doprnt.c (doprnt):
15036 * xdisp.c (vmessage):
15037 Use ptrdiff_t, not size_t, when using or implementing doprnt,
15038 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
15039 prefer signed arithmetic to avoid comparison confusion.
15040 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
15041 but is a bit tricky.
15043 Assume freestanding C89 headers, string.h, stdlib.h.
15044 * data.c, doprnt.c, floatfns.c, print.c:
15045 Include float.h unconditionally.
15046 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
15047 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
15048 * regex.c: Likewise for stddef.h, string.h.
15049 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
15050 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
15051 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
15052 (STDC_HEADERS): Remove obsolete defines.
15053 * sysdep.c: Include limits.h unconditionally.
15055 Assume support for memcmp, memcpy, memmove, memset.
15056 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
15057 * regex.c (memcmp, memcpy):
15058 Remove; we assume C89 now.
15060 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
15061 (__malloc_safe_bcopy): Remove; no longer needed.
15063 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
15064 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
15065 well either way, and we prefer signed to unsigned.
15067 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
15069 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
15070 closes the connection while we're reading (bug#9182).
15072 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
15074 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
15075 are specified (Bug#9168).
15077 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
15079 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
15080 Found by GCC static checking and --with-wide-int on a 32-bit host.
15082 2011-07-25 Eli Zaretskii <eliz@gnu.org>
15084 * xdisp.c (compute_display_string_pos): Fix logic of caching
15085 previous display string position. Initialize cached_prev_pos to
15086 -1. Fixes slow-down at the beginning of a buffer.
15088 2011-07-24 Eli Zaretskii <eliz@gnu.org>
15090 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
15091 for attrs[LFACE_FONTSET_INDEX].
15093 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
15095 * xml.c (parse_region): Remove unused local
15096 that was recently introduced.
15098 2011-07-23 Eli Zaretskii <eliz@gnu.org>
15100 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
15101 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
15103 * xdisp.c (move_it_in_display_line_to): Record the best matching
15104 position for TO_CHARPOS while scanning the line, and restore it on
15105 exit if none of the characters scanned was an exact match.
15106 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
15107 when exact match is impossible due to invisible text, and the
15108 lines are truncated.
15110 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
15112 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
15115 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15117 Fix a significant slow-down of cursor motion with C-n, C-p,
15118 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
15119 auto-repeat under bidi redisplay in fontified buffers.
15120 * xdisp.c (compute_stop_pos_backwards): New function.
15121 (next_element_from_buffer): Call compute_stop_pos_backwards to
15122 find a suitable prev_stop when we find ourselves before
15124 (reseat): Don't look for prev_stop, as that could mean a very long
15126 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
15127 <cached_disp_overlay_modiff>: Cache for last found display string
15129 (compute_display_string_pos): Return the cached position if asked
15130 about the same buffer in the same area of character positions, and
15131 the buffer wasn't changed since the time the display string
15132 position was cached.
15134 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15136 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
15137 is an integer, which is important for empty lines. (Bug#9149)
15139 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
15141 * frame.c (Fmodify_frame_parameters): In tty case, update the
15142 default face if necessary (Bug#4238).
15144 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
15146 * editfns.c (Fstring_to_char): No need to explain what a character
15147 is in the docstring (Bug#6576).
15149 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15151 * xml.c (parse_region): Make sure we always return a tree.
15153 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
15155 * xml.c (parse_region): If a document contains only comments,
15158 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15160 * xml.c (make_dom): Return comments, too.
15162 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
15165 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
15166 and the surrounding thread.
15167 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
15168 rather than fgets, and retry after EINTR. Otherwise, 'emacs
15169 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
15171 * s/openbsd.h (BROKEN_SIGIO): Define.
15172 * unexelf.c (unexec) [__OpenBSD__]:
15173 Don't update the .mdebug section of the Alpha COFF symbol table.
15175 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15177 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
15180 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
15182 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
15183 This fixes some race conditions on the permissions of any newly
15186 * alloc.c (valid_pointer_p): Use pipe, not open.
15187 This fixes some permissions issues when debugging.
15189 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
15190 If fchown fails to set both uid and gid, try to set just gid,
15191 as that is sometimes allowed. Adjust the file's mode to eliminate
15192 setuid or setgid bits that are inappropriate if fchown fails.

15212 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
15213 This works around a problem with the previous change to Fcopy_file.
15214 Recent glibc declares fchown with __attribute__((warn_unused_result)),
15215 and without this change, GCC might complain about discarding
15216 fchown's return value.
15218 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
15220 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).

15243 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
15245 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
15246 quotes the next character, and doesn't affect other longer
15247 sequences (bug#8935).
15249 * lread.c (syms_of_lread): Clarify that is isn't only
15250 `eval-buffer' and `eval-defun' that's affected by

15261 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
15262 (elsz): Now a signed constant, not a size_t var. We prefer signed
15263 types to unsigned, to avoid integer comparison confusion. Without
15264 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
15265 "cannot optimize loop, the loop counter may overflow", a symptom
15267 * indent.c (Fvertical_motion): Mark locals as initialized.
15268 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
15270 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>

15297 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
15298 original value of -1 will not work with bidi.)
15299 (compute_display_string_pos): First arg is now struct

15308 Fix calculation of the object to scan. Fixes an error when using

15311 base_level_stop; instead, set base_level_stop to BEGV.
15312 Fixes crashes in vertical-motion.
15313 (next_element_from_buffer): Improve commentary for when
15314 the iterator is before prev_stop.
15315 (init_iterator): Initialize bidi_p from the default value of

15356 pushed the iterator stack, restore the internal state of the bidi
15357 iterator by calling bidi_pop_it same number of times.
15358 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
15359 and we are bidi-iterating, don't decrement the iterator position;
15360 instead, set the first_elt flag in the bidi iterator, to produce
15362 (reseat_1): Remove redundant setting of string_from_display_prop_p.
15363 (push_display_prop): xassert that we are iterating a buffer.

15367 (push_display_prop): Set up the `unibyte' member of bidi_it.string
15368 correctly. Don't assume unibyte strings are not bidi-reordered.

15792 (clone_per_buffer_values): Don't assume that

15794 This isn't true in general, and it's particularly not true
15795 if Emacs is configured with --with-wide-int.
15796 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
15797 New macros, used in the buffer.c change.

15833 Random fixes. E.g., (random) never returned negative values.
15834 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
15835 subseconds part to the entropy, as that's a bit more random.
15836 Prefer signed to unsigned, since the signedness doesn't matter and
15837 in general we prefer signed. When given a limit, use a
15838 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
15839 latter isn't right if USE_2_TAGS_FOR_INTS.
15840 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
15841 not 0..VALMASK. Don't discard "excess" bits that random () returns.

15845 * textprop.c (text_property_stickiness):

15853 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
15854 This is more efficient than Ffile_directory_p and avoids a minor race.
15856 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
15858 * buffer.c (Foverlay_put): Say what the return value is
15861 * fileio.c (barf_or_query_if_file_exists): Check first if the file
15862 is a directory before asking whether to use the file name
15864 (barf_or_query_if_file_exists): Make the "File is a directory"
15865 error be more correct.
15867 * fns.c (Frequire): Remove the mention of the .gz files, since
15868 that's installation-specific, but keep the mention of
15869 `get-load-suffixes'.

15873 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

15881 Qgnutls_bootprop_verify_error (which is no longer used).
15883 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
15884 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
15885 Also (re)move comments that are misplaced or no longer relevant.

15914 * lread.c (syms_of_lread): Mention single symbols defined by
15915 `defvar' or `defconst' (bug#7154).
15917 * fns.c (Frequire): Mention .el.gz files (bug#7314).

15986 * eval.c (struct backtrace): Simplify and port the data structure.
15987 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
15988 signed bit field, as this assumption is not portable and it makes
15989 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
15990 "char debug_on_exit : 1" as this is not portable either; instead,
15991 use the portable "unsigned int debug_on_exit : 1". Remove unused
15992 member evalargs. Remove obsolete comments about cc bombing out.
15994 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

16066 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
16067 and use min_width/height from frames size_hint to set
16068 min_width/height (Bug#8919).
16070 * gtkutil.c (xg_create_frame_widgets): Pass f to emacs_fixed_new.
16071 (x_wm_set_size_hint): Remove call to emacs_fixed_set_min_size.
16074 2011-06-26 Eli Zaretskii <eliz@gnu.org>
16076 * bidi.c (bidi_paragraph_init): Test for ZV_BYTE before calling
16077 bidi_at_paragraph_end, since fast_looking_at doesn't like to be
16080 2011-06-26 Chong Yidong <cyd@stupidchicken.com>
16082 * process.c (wait_reading_process_output): Bypass select if
16083 waiting for a cell while ignoring keyboard input, and input is
16084 pending. Suggested by Jan Djärv (Bug#8869).
16086 2011-06-25 Paul Eggert <eggert@cs.ucla.edu>
16088 Use gnulib's dup2 module instead of rolling our own.
16089 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.
16091 2011-06-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16093 * dispnew.c (scrolling_window): Before scrolling, turn off a

16156 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
16158 Integer and buffer overflow fixes (Bug#8873).
16160 * print.c (printchar, strout): Check for string overflow.
16161 (PRINTPREPARE, printchar, strout):
16162 Don't set size unless allocation succeeds.
16164 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
16165 for sizes. Check for string overflow more accurately.
16166 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
16168 * macros.c: Integer and buffer overflow fixes.
16169 * keyboard.h (struct keyboard.kbd_macro_bufsize):
16170 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
16171 Use ptrdiff_t, not int, for sizes.
16172 Don't increment bufsize until after realloc succeeds.
16173 Check for size-calculation overflow.
16174 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
16176 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
16178 * lread.c: Integer overflow fixes.
16179 (read_integer): Radix is now EMACS_INT, not int,
16180 to improve quality of diagnostics for out-of-range radices.
16181 Calculate buffer size correctly for out-of-range radices.
16182 (read1): Check for integer overflow in radices, and in
16183 read-circle numbers.
16184 (read_escape): Avoid int overflow.
16185 (Fload, openp, read_buffer_size, read1)
16186 (substitute_object_recurse, read_vector, read_list, map_obarray):
16187 Use ptrdiff_t, not int, for sizes.

16202 2011-06-22 Leo Liu <sdl.web@gmail.com>
16204 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
16205 Move to minibuffer.el.
16207 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
16209 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
16210 The following patches are for when GLYPH_DEBUG && !XASSERT.
16211 * dispextern.h (trace_redisplay_p, dump_glyph_string):
16212 * dispnew.c (flush_stdout):
16213 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
16214 Mark as externally visible.
16215 * dispnew.c (check_window_matrix_pointers): Now static.
16216 * dispnew.c (window_to_frame_vpos):
16217 * xfns.c (unwind_create_frame):
16218 * xterm.c (x_check_font): Remove unused local.
16219 * scroll.c (CHECK_BOUNDS):
16220 * xfaces.c (cache_fache): Rename local to avoid shadowing.
16221 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
16222 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
16223 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
16224 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
16226 (debug_method_add): Use va_list and vsprintf rather than relying
16227 on undefined behavior with wrong number of arguments.
16228 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
16229 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
16230 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
16231 since we're not interested in debugging glyphs with old libraries.
16232 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
16233 GCC 4.6.0's static checking.
16235 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
16237 Integer overflow and signedness fixes (Bug#8873).

16246 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
16247 (x_create_bitmap_from_xpm_data):
16248 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
16249 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
16251 * xfaces.c (load_pixmap):
16252 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
16253 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
16254 (.bitmaps_last, struct x_output.icon_bitmap):
16255 Use ptrdiff_t, not int, for bitmap indexes.
16256 (x_allocate_bitmap_record): Check for size overflow.
16257 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
16259 Use ptrdiff_t, not int, for overlay counts.
16260 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
16261 * editfns.c (overlays_around, get_pos_property):
16262 * textprop.c (get_char_property_and_overlay):
16263 * xdisp.c (next_overlay_change, note_mouse_highlight):
16264 * xfaces.c (face_at_buffer_position):
16265 * buffer.c (OVERLAY_COUNT_MAX): New macro.
16266 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
16267 (Fnext_overlay_change, Fprevious_overlay_change)
16268 (mouse_face_overlay_overlaps, Foverlays_in):
16269 Use ptrdiff_t, not int, for sizes.
16270 (overlays_at, overlays_in): Check for size-calculation overflow.
16272 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
16274 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
16275 (x_session_initialize): Do not assume string length fits in int.
16277 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
16278 This is unlikely, but can occur if DPI is outlandish.
16280 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
16281 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
16283 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
16284 * xrdb.c (magic_file_p, search_magic_path):
16285 Omit last arg SUFFIX; it was always 0. All callers changed.
16286 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
16288 * xfont.c (xfont_match): Avoid need for strlen.
16290 * xfns.c: Don't assume strlen fits in int.
16291 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
16293 * xdisp.c (message_log_check_duplicate): Return intmax_t,
16294 not unsigned long, as we prefer signed integers. All callers changed.
16295 Detect integer overflow in repeat count.
16296 (message_dolog): Don't assume print length fits in 39 bytes.
16297 (display_mode_element): Don't assume strlen fits in int.
16299 * termcap.c: Don't assume sizes fit in int and never overflow.
16300 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
16301 (gobble_line): Check for size-calculation overflow.
16303 * minibuf.c (Fread_buffer):
16304 * lread.c (intern, intern_c_string):
16305 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

16309 * gtkutil.c (style_changed_cb): Avoid need for strlen.
16311 * font.c: Don't assume string length fits in int.
16312 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
16313 Use ptrdiff_t, not int.
16314 (font_intern_prop): Don't assume string length fits in int.
16315 Don't assume integer property fits in fixnum.
16316 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
16318 * filelock.c: Fix some buffer overrun and integer overflow issues.
16319 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
16320 Reformulate so as not to need the command string.
16321 Invoke gzip -cd rather than gunzip, as it's more portable.
16322 (lock_info_type, lock_file_1, lock_file):
16323 Don't assume pid_t and time_t fit in unsigned long.
16324 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
16325 (current_lock_owner): Prefer signed type for sizes.
16326 Use memcpy, not strncpy, where memcpy is what is really wanted.
16327 Don't assume (via atoi) that time_t and pid_t fit in int.
16328 Check for time_t and/or pid_t out of range, e.g., via a network share.
16329 Don't alloca where an auto var works fine.
16331 * fileio.c: Fix some integer overflow issues.
16332 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
16333 Don't assume string length fits in int.
16334 (directory_file_name): Don't assume string length fits in long.
16335 (make_temp_name): Don't assume pid fits in int, or that its print
16336 length is less than 20.
16338 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
16340 * coding.c (make_subsidiaries): Don't assume string length fits in int.
16342 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
16344 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
16345 We prefer signed integers, even for size calculations.
16347 * emacs.c: Don't assume string length fits in 'int'.
16348 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
16349 (main): Don't invoke strlen when not needed.
16351 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
16352 (XD_DEBUG_MESSAGE): Don't waste a byte.
16354 * callproc.c (getenv_internal_1, getenv_internal)
16355 (Fgetenv_internal):
16356 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
16358 * lread.c (invalid_syntax): Omit length argument.
16359 All uses changed. This doesn't fix a bug, but it simplifies the
16360 code away from its former Hollerith-constant appearance, and it's
16361 one less 'int' to worry about when looking at integer-overflow issues.
16362 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
16364 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
16365 This didn't break anything, but it didn't help either.
16366 It's confusing to put a bogus integer in a place where the actual
16367 value does not matter.
16368 (LIST_END_P): Remove unused macro and its bogus comment.
16369 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
16371 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
16372 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
16374 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
16375 We prefer signed types, and the value cannot exceed the EMACS_INT
16376 range anyway (because otherwise the length would not be representable).
16377 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
16378 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
16379 This avoids a GCC warning when WIDE_EMACS_INT.
16381 * indent.c (sane_tab_width): New function.
16382 (current_column, scan_for_column, Findent_to, position_indentation)
16383 (compute_motion): Use it. This is just for clarity.
16384 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
16386 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
16388 * lisp.h (lint_assume): New macro.
16389 * composite.c (composition_gstring_put_cache):
16390 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
16392 * editfns.c, insdel.c:
16393 Omit unnecessary forward decls, to simplify future changes.
16395 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
16397 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
16399 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
16400 Use much-faster test for byte-length change.
16401 Don't assume string byte-length fits in 'int'.
16402 Check that character arg fits in 'int'.
16403 (mapcar1): Declare byte as byte, for clarity.
16405 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
16407 * fns.c (concat): Catch string overflow earlier.
16408 Do not rely on integer wraparound.
16410 * dispextern.h (struct it.overlay_strings_charpos)
16411 (struct it.selective): Now EMACS_INT, not int.
16412 * xdisp.c (forward_to_next_line_start)
16413 (back_to_previous_visible_line_start)
16414 (reseat_at_next_visible_line_start, next_element_from_buffer):
16415 Don't arbitrarily truncate the value of 'selective' to int.
16417 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
16419 * composite.c: Don't truncate sizes to 'int'.
16420 (composition_gstring_p, composition_reseat_it)
16421 (composition_adjust_point): Use EMACS_INT, not int.
16422 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
16423 not EMACS_UINT, for indexes.
16425 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
16427 * buffer.c: Include <verify.h>.
16428 (struct sortvec.priority, struct sortstr.priority):
16429 Now EMACS_INT, not int.
16430 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
16431 (struct sortstr.size, record_overlay_string)
16432 (struct sortstrlist.size, struct sortlist.used):
16433 Don't truncate size to int.
16434 (record_overlay_string): Check for size-calculation overflow.
16435 (init_buffer_once): Check at compile-time, not run-time.
16437 2011-06-22 Jim Meyering <meyering@redhat.com>
16439 Don't leak an XBM-image-sized buffer
16440 * image.c (xbm_load): Free the image buffer after using it.
16442 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
16445 * composite.c (find_automatic_composition): Omit needless 'return 0;'
16446 that Sun C diagnosed.
16447 * fns.c (secure_hash): Fix pointer signedness issue.
16448 * intervals.c (static_offset_intervals): New function.
16449 (offset_intervals): Use it.
16451 2011-06-21 Leo Liu <sdl.web@gmail.com>
16454 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
16457 * fns.c (secure_hash): Rename from crypto_hash_function and change
16458 the first arg to accept symbols.
16459 (Fsecure_hash): New primitive.
16460 (syms_of_fns): New symbols.
16462 2011-06-20 Deniz Dogan <deniz@dogan.se>
16464 * process.c (Fset_process_buffer): Clarify return value in
16467 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
16469 * dispnew.c (add_window_display_history): Use BVAR.
16471 * xdisp.c (debug_method_add): Use BVAR.
16472 (check_window_end, dump_glyph_matrix, dump_glyph)
16473 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
16475 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
16478 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
16479 check till after the cache is created in init_frame_faces.
16481 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
16483 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
16485 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
16487 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
16488 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
16489 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
16491 Improve buffer-overflow checking (Bug#8873).
16492 * fileio.c (Finsert_file_contents):
16493 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
16494 Remove the old (too-loose) buffer overflow checks.
16495 They weren't needed, since make_gap checks for buffer overflow.
16496 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
16497 The old code merely checked for Emacs fixnum overflow, and relied
16498 on undefined (wraparound) behavior. The new code avoids undefined
16499 behavior, and also checks for ptrdiff_t and/or size_t overflow.
16501 * editfns.c (Finsert_char): Don't dump core with very negative counts.
16502 Tune. Don't use wider integers than needed. Don't use alloca.
16503 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
16505 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
16507 * insdel.c, lisp.h (buffer_overflow): New function.
16508 (insert_from_buffer_1, replace_range, replace_range_2):
16509 * insdel.c (make_gap_larger):
16510 * editfns.c (Finsert_char):
16511 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
16513 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
16515 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
16517 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
16519 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
16520 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
16522 * fileio.c: Don't assume EMACS_INT fits in off_t.
16523 (emacs_lseek): New static function.
16524 (Finsert_file_contents, Fwrite_region): Use it.
16525 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
16527 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
16529 * fns.c: Don't overflow int when computing a list length.
16530 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
16531 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
16532 truncation on 64-bit hosts. Check for QUIT every
16533 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
16534 faster and is responsive enough.
16535 (Flength): Report an error instead of overflowing an integer.
16536 (Fsafe_length): Return a float if the value is not representable
16537 as a fixnum. This shouldn't happen except in contrived situations.
16538 (Fnthcdr, Fsort): Don't assume list length fits in int.
16539 (Fcopy_sequence): Don't assume vector length fits in int.
16541 * alloc.c: Check that resized vectors' lengths fit in fixnums.
16542 (header_size, word_size): New constants.
16543 (allocate_vectorlike): Don't check size overflow here.
16544 (allocate_vector): Check it here instead, since this is the only
16545 caller of allocate_vectorlike that could cause overflow.
16546 Check that the new vector's length is representable as a fixnum.
16548 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
16549 The previous code was bogus. For example, next_almost_prime (32)
16550 returned 39, which is undesirable as it is a multiple of 3; and
16551 next_almost_prime (24) returned 25, which is a multiple of 5 so
16552 why was the code bothering to check for multiples of 7?
16554 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
16556 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
16558 Variadic C functions now count arguments with ptrdiff_t.
16559 This partly undoes my 2011-03-30 change, which replaced int with size_t.
16560 Back then I didn't know that the Emacs coding style prefers signed int.
16561 Also, in the meantime I found a few more instances where arguments
16562 were being counted with int, which may truncate counts on 64-bit
16563 machines, or EMACS_INT, which may be unnecessarily wide.
16564 * lisp.h (struct Lisp_Subr.function.aMANY)
16565 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
16566 Arg counts are now ptrdiff_t, not size_t.
16567 All variadic functions and their callers changed accordingly.
16568 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
16569 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
16570 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
16571 * callint.c (Fcall_interactively): Check arg count for overflow,
16572 to avoid potential buffer overrun. Use signed char, not 'int',
16573 for 'varies' array, so that we needn't bother to check its size
16574 calculation for overflow.
16575 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
16576 * eval.c (apply_lambda):
16577 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
16578 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
16579 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
16581 * callint.c (Fcall_interactively): Don't use index var as event count.
16583 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
16584 * mem-limits.h (SIZE): Remove; no longer used.
16586 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
16588 Remove unnecessary casts.
16589 * xterm.c (x_term_init):
16590 * xfns.c (x_set_border_pixel):
16591 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
16592 These aren't needed now that we assume ANSI C.
16594 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
16595 It's more likely to cause problems (due to unsigned overflow)
16598 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
16600 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
16602 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
16604 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
16606 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
16608 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
16610 GLYPH_CODE_FACE returns EMACS_INT, not int.
16611 * dispextern.h (merge_faces):
16612 * xfaces.c (merge_faces):
16613 * xdisp.c (get_next_display_element, next_element_from_display_vector):
16614 Don't assume EMACS_INT fits in int.
16616 * character.h (CHAR_VALID_P): Remove unused parameter.
16617 * fontset.c, lisp.h, xdisp.c: All uses changed.
16619 * editfns.c (Ftranslate_region_internal): Omit redundant test.
16621 * fns.c (concat): Minor tuning based on overflow analysis.
16622 This doesn't fix any bugs. Use int to hold character, instead
16623 of constantly refetching from Emacs object. Use XFASTINT, not
16624 XINT, for value known to be a character. Don't bother comparing
16625 a single byte to 0400, as it's always less.
16627 * floatfns.c (Fexpt):
16628 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
16630 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
16633 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
16635 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
16636 Without this fix, on a 64-bit host (aset S 0 4294967386) would
16637 incorrectly succeed when S was a string, because 4294967386 was
16638 truncated before it was used.
16640 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
16641 Otherwise, an out-of-range integer could cause undefined behavior
16644 * composite.c: Use int, not EMACS_INT, for characters.
16645 (fill_gstring_body, composition_compute_stop_pos): Use int, not
16646 EMACS_INT, for values that are known to be in character range.
16647 This doesn't fix any bugs but is the usual style inside Emacs and
16648 may generate better code on 32-bit machines.
16650 Make sure a 64-bit char is never passed to ENCODE_CHAR.
16651 This is for reasons similar to the recent CHAR_STRING fix.
16652 * charset.c (Fencode_char): Check that character arg is actually
16653 a character. Pass an int to ENCODE_CHAR.
16654 * charset.h (ENCODE_CHAR): Verify that the character argument is no
16655 wider than 'int', as a compile-time check to prevent future regressions
16658 * character.c (char_string): Remove unnecessary casts.
16660 Make sure a 64-bit char is never passed to CHAR_STRING.
16661 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
16662 by silently ignoring the top 32 bits, allowing some values
16663 that were far too large to be valid characters.
16664 * character.h: Include <verify.h>.
16665 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
16666 arguments are no wider than unsigned, as a compile-time check
16667 to prevent future regressions in this area.
16669 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
16670 (Fsubst_char_in_region):
16672 * xdisp.c (decode_mode_spec_coding):
16673 Adjust to CHAR_STRING's new requirement.
16674 * editfns.c (Finsert_char, Fsubst_char_in_region):
16675 * fns.c (concat): Check that character args are actually
16676 characters. Without this test, these functions did the wrong
16677 thing with wildly out-of-range values on 64-bit hosts.
16679 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
16680 These casts should not be needed on 32-bit hosts, either.
16681 * keyboard.c (read_char):
16682 * lread.c (Fload): Remove casts to unsigned.
16684 * lisp.h (UNSIGNED_CMP): New macro.
16685 This fixes comparison bugs on 64-bit hosts.
16686 (ASCII_CHAR_P): Use it.
16687 * casefiddle.c (casify_object):
16688 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
16689 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
16690 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
16691 * dispextern.h (FACE_FROM_ID):
16692 * keyboard.c (read_char): Use UNSIGNED_CMP.
16694 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
16695 not to EMACS_INT, to avoid GCC warning.
16697 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
16699 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
16700 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
16701 isn't needed on 32-bit machines.
16703 * buffer.c (Fgenerate_new_buffer_name):
16704 Use EMACS_INT for count, not int.
16705 (advance_to_char_boundary): Return EMACS_INT, not int.
16707 * data.c (Qcompiled_function): Now static.
16709 * window.c (window_body_lines): Now static.
16711 * image.c (gif_load): Rename local to avoid shadowing.
16713 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
16714 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
16715 * alloc.c (make_save_value): Integer argument is now of type
16716 ptrdiff_t, not int.
16717 (mark_object): Use ptrdiff_t, not int.
16718 * lisp.h (pD): New macro.
16719 * print.c (print_object): Use it.
16721 * alloc.c: Use EMACS_INT, not int, to count objects.
16722 (total_conses, total_markers, total_symbols, total_vector_size)
16723 (total_free_conses, total_free_markers, total_free_symbols)
16724 (total_free_floats, total_floats, total_free_intervals)
16725 (total_intervals, total_strings, total_free_strings):
16726 Now EMACS_INT, not int. All uses changed.
16727 (Fgarbage_collect): Compute overall total using a double, so that
16728 integer overflow is less likely to be a problem. Check for overflow
16729 when converting back to an integer.
16730 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
16731 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
16732 These were 'int' variables that could overflow on 64-bit hosts;
16733 they were never used, so remove them instead of repairing them.
16734 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
16735 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
16736 Previously, this ceilinged at INT_MAX, but that doesn't work on
16738 (allocate_pseudovector): Don't use EMACS_INT when int would do.
16740 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
16741 (allocate_vectorlike): Check for ptrdiff_t overflow.
16742 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
16743 when a (possibly-narrower) signed value would do just as well.
16744 We prefer using signed arithmetic, to avoid comparison confusion.
16746 * alloc.c: Catch some string size overflows that we were missing.
16747 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
16748 for convenience in STRING_BYTES_MAX.
16749 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
16750 The definition here is exact; the one in lisp.h was approximate.
16751 (allocate_string_data): Check for string overflow. This catches
16752 some instances we weren't catching before. Also, it catches
16753 size_t overflow on (unusual) hosts where SIZE_MAX <= min
16754 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
16755 and ptrdiff_t and EMACS_INT are both 64 bits.
16757 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
16758 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
16759 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
16761 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
16763 * alloc.c (Fmake_string): Check for out-of-range init.
16765 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
16767 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
16769 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
16771 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
16772 xg_get_default_scrollbar_width.
16774 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
16775 (int_gtk_range_get_value): Move to the scroll bar part of the file.
16776 (style_changed_cb): Call update_theme_scrollbar_width and call
16777 x_set_scroll_bar_default_width and xg_frame_set_char_size for
16778 all frames (Bug#8505).
16779 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
16780 Call gtk_window_set_resizable if HAVE_GTK3.
16781 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
16782 and height if HAVE_GTK3 (Bug#8505).
16783 (scroll_bar_width_for_theme): New variable.
16784 (update_theme_scrollbar_width): New function.
16785 (xg_get_default_scrollbar_width): Move code to
16786 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
16787 (xg_initialize): Call update_theme_scrollbar_width.
16789 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
16791 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
16793 2011-06-12 Martin Rudalics <rudalics@gmx.at>
16795 * frame.c (make_frame): Call other_buffer_safely instead of
16798 * window.c (temp_output_buffer_show): Call display_buffer with
16799 second argument Vtemp_buffer_show_specifiers and reset latter
16800 immediately after the call.
16801 (Vtemp_buffer_show_specifiers): New variable.
16802 (auto_window_vscroll_p, next_screen_context_lines)
16803 (Vscroll_preserve_screen_position): Remove leading asterisks from
16806 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
16808 Fix minor problems found by GCC 4.6.0 static checking.
16809 * buffer.c (Qclone_number): Remove for now, as it's unused.
16810 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
16811 (record_buffer): Remove unused local.
16812 * frame.c (other_visible_frames, frame_buffer_list): Now static.
16813 (set_frame_buffer_list): Remove; unused.
16814 * frame.h (other_visible_frames): Remove decl.
16815 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
16816 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
16817 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
16819 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
16820 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
16821 Define only if HAVE_GPM.
16822 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
16823 (update_hints_inhibit): Remove; never set. All uses removed.
16824 * widgetprv.h (emacsFrameClassRec): Remove decl.
16825 * window.c (delete_deletable_window): Now returns void, since it
16826 wasn't returning anything.
16827 (compare_window_configurations): Remove unused locals.
16828 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
16829 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
16830 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
16831 the same widths as pointers. This follows up on the 2011-05-06 patch.
16832 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
16833 * xterm.h: Likewise.
16834 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.

16839 (LISP_H): Add lib/intprops.h.
16841 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
16843 * image.c (gif_load): Add animation frame delay to the metadata.
16844 (syms_of_image): Use DEFSYM. New symbol `delay'.
16846 2011-06-11 Martin Rudalics <rudalics@gmx.at>
16848 * window.c (delete_deletable_window): Re-add.
16849 (Fset_window_configuration): Rewrite to handle dead buffers and
16850 consequently deletable windows.
16851 (window_tree, Fwindow_tree): Remove. Supply functionality in
16853 (compare_window_configurations): Simplify code.
16855 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
16857 * image.c (imagemagick_load_image): Fix type mismatch.
16858 (Fimagemagick_types): Likewise.
16860 * window.h (replace_buffer_in_windows): Declare.
16862 2011-06-11 Martin Rudalics <rudalics@gmx.at>
16864 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
16865 Qclone_number. Remove external declaration of Qdelete_window.
16866 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
16868 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
16869 Run Qbuffer_list_update_hook if allowed.
16870 (Fother_buffer): Rewrite doc-string. Major rewrite for new
16871 buffer list implementation.
16872 (other_buffer_safely): New function.
16873 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
16874 calls to replace_buffer_in_windows and
16875 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
16877 (record_buffer): Inhibit quitting and rewrite using quittable
16878 functions. Run Qbuffer_list_update_hook if allowed.
16879 (Frecord_buffer, Funrecord_buffer): New functions.
16880 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
16881 Move switch-to-buffer to window.el.
16882 (bury-buffer): Move to window.el.
16883 (Vbuffer_list_update_hook): New variable.
16885 * lisp.h (other_buffer_safely): Add prototype in buffer.c
16888 * window.h (resize_frame_windows): Move up in code.
16889 (Fwindow_frame): Remove EXFUN.
16890 (replace_buffer_in_all_windows): Remove prototype.
16891 (replace_buffer_in_windows_safely): Add prototype.
16893 * window.c: Declare Qdelete_window static again. Move down
16894 declaration of select_count.
16895 (Fnext_window, Fprevious_window): Rewrite doc-strings.
16896 (Fother_window): Move to window.el.
16897 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
16898 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.
16899 (Fdelete_windows_on, Freplace_buffer_in_windows): Move to
16901 (replace_buffer_in_windows): Implement by calling
16902 Qreplace_buffer_in_windows.
16903 (replace_buffer_in_all_windows): Remove with some functionality
16904 moved into replace_buffer_in_windows_safely.
16905 (replace_buffer_in_windows_safely): New function.
16906 (select_window_norecord, select_frame_norecord): Move in front
16907 of run_window_configuration_change_hook. Remove now obsolete
16909 (Fset_window_buffer): Rewrite doc-string.
16910 Call Qrecord_window_buffer.
16911 (keys_of_window): Move binding for other-window to window.el.
16913 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
16915 * dispextern.h (struct image): Replace data member, whose int_val
16916 and ptr_val fields were not used by anything, with a single
16919 * image.c (Fimage_metadata, make_image, mark_image, tiff_load)
16920 (gif_clear_image, gif_load, imagemagick_load_image)
16921 (gs_clear_image, gs_load): Callers changed.

17386 (compute_display_string_pos, compute_display_string_end):
17387 Declare prototypes.
17388 (struct bidi_it): New members nchars and disp_pos. ch_len is now
17391 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
17393 Malloc failure behavior now depends on size of allocation.
17394 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
17395 * lisp.h: Change signatures accordingly.
17396 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
17397 All callers changed. (Bug#8762)
17399 * gnutls.c: Use Emacs's memory allocators.
17400 Without this change, the gnutls library would invoke malloc etc.
17401 directly, which causes problems on non-SYNC_INPUT hosts, and which
17402 runs afoul of improving memory_full behavior. (Bug#8761)
17403 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
17404 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
17405 xfree instead of the default malloc, realloc, free.
17406 (Fgnutls_boot): No need to check for memory allocation failure,
17407 since xmalloc does that for us.
17409 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
17410 * category.c (hash_get_category_set):
17411 * ccl.c (ccl_driver):
17412 * charset.c (Fdefine_charset_internal):

17423 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
17424 (Fsxhash, Fgethash, Fputhash, Fmaphash):
17425 * image.c (make_image, search_image_cache, lookup_image)
17426 (xpm_put_color_table_h):
17427 * lisp.h (struct Lisp_Hash_Table):
17428 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
17429 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
17430 for hashes and hash indexes, instead of 'unsigned' and 'int'.
17431 * alloc.c (allocate_vectorlike):
17432 Check for overflow in vector size calculations.
17433 * ccl.c (ccl_driver):
17434 Check for overflow when converting EMACS_INT to int.
17435 * fns.c, image.c: Remove unnecessary static decls that would otherwise
17436 need to be updated by these changes.
17437 * fns.c (make_hash_table, maybe_resize_hash_table):
17438 Check for integer overflow with large hash tables.
17439 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
17440 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
17441 (SXHASH_REDUCE): New macro.
17442 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
17443 Use it instead of discarding useful hash info with large hash values.
17444 (sxhash_float): New function.
17445 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
17446 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
17447 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
17448 Rewrite to use FIXNUM_BITS, as this simplifies things.
17449 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
17450 Adjust signatures to match updated version of code.
17451 (consing_since_gc): Now EMACS_INT, since a single hash table can
17452 use more than INT_MAX bytes.
17454 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
17456 Make it possible to build with GCC-4.6+ -O2 -flto.
17458 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
17460 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
17462 * minibuf.c (get_minibuffer, read_minibuf_unwind):
17463 Call minibuffer-inactive-mode.
17465 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
17467 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
17468 Update dependencies.
17470 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17472 * data.c (init_data): Remove code for UTS, this system is not
17475 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17477 Don't force ./temacs to start in terminal mode.
17479 * frame.c (make_initial_frame): Initialize faces in all cases, not
17480 only when CANNOT_DUMP is defined.
17481 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
17483 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17485 * dispnew.c (add_window_display_history): Use const for the string
17486 pointer. Remove declaration, not needed.
17488 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
17490 Use 'inline', not 'INLINE'.
17491 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
17492 * alloc.c, fontset.c (INLINE): Remove.
17493 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
17494 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
17495 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
17496 * gmalloc.c (register_heapinfo): Use inline unconditionally.
17497 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
17499 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17501 Make it possible to run ./temacs.
17503 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
17504 syms_of_callproc does the same thing. Remove test for
17505 "initialized", do it in the caller.
17506 * emacs.c (main): Avoid calling set_initial_environment when dumping.
17508 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
17510 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
17511 (read_minibuf): Use get_minibuffer.
17512 (syms_of_minibuf): Use DEFSYM.
17513 (Qmetadata): New var.
17514 * data.c (Qbuffer): Don't make it static.
17515 (syms_of_data): Use DEFSYM.
17517 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
17519 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
17520 (CCL_CODE_MIN): New macro.
17522 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
17524 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
17526 * eval.c (Qdebug): Now static.
17527 * lisp.h (Qdebug): Remove decl. This reverts a part of the
17528 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
17529 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
17531 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
17533 * image.c: Various fixes to ImageMagick code comments.
17534 (Fimagemagick_types): Doc fix.
17536 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
17538 Minor fixes prompted by GCC 4.6.0 warnings.
17540 * xselect.c (converted_selections, conversion_fail_tag): Now static.
17542 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
17543 (x_clipboard_manager_save_all): Move extern decl to ...
17544 * xterm.h: ... here, so that it can be checked for consistency.
17546 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
17548 * xselect.c (x_clipboard_manager_save_frame)
17549 (x_clipboard_manager_save_all): New functions.
17550 (Fx_clipboard_manager_save): Lisp function deleted.
17552 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
17553 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
17555 * xterm.h: Update prototype.
17557 2011-05-28 William Xu <william.xwl@gmail.com>
17559 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
17560 exiting (Bug#8239).
17562 2011-05-28 Jim Meyering <meyering@redhat.com>
17564 Avoid a sign-extension bug in crypto_hash_function.
17565 * fns.c (to_uchar): Define.
17566 (crypto_hash_function): Use it to convert some newly-signed
17567 variables to unsigned, to avoid sign-extension bugs. For example,
17568 without this change, (md5 "truc") would evaluate to
17569 45723a2aff78ff4fff7fff1114760e62 rather than the expected
17570 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
17571 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
17573 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17575 Integer overflow fixes.
17577 * dbusbind.c: Serial number integer overflow fixes.
17578 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
17579 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
17580 to hold a serial number that is too large for a fixnum.
17581 (Fdbus_method_return_internal, Fdbus_method_error_internal):
17582 Check for serial numbers out of range. Decode any serial number
17583 that was so large that it became a float. (Bug#8722)
17585 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
17586 (Fdbus_call_method, Fdbus_call_method_asynchronously):
17587 Use XFASTINT rather than XUINT when numbers are nonnegative.
17588 (xd_append_arg, Fdbus_method_return_internal):
17589 (Fdbus_method_error_internal): Likewise. Also, for unsigned
17590 arguments, check that Lisp number is nonnegative, rather than
17591 silently wrapping negative numbers around. (Bug#8722)
17592 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
17595 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
17597 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
17599 ccl: Add integer overflow checks.
17600 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
17601 (IN_INT_RANGE): New macros.
17602 (ccl_driver): Use them to check for integer overflow when
17603 decoding a CCL program. Many of the new checks are whether XINT (x)
17604 fits in int; it doesn't always, on 64-bit hosts. The new version
17605 doesn't catch all possible integer overflows, but it's an
17606 improvement. (Bug#8719)
17608 * alloc.c (make_event_array): Use XINT, not XUINT.
17609 There's no need for unsigned here.
17611 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
17612 This follows up to the 2011-05-06 change that substituted uintptr_t
17613 for EMACS_INT. This case wasn't caught back then.
17615 Rework Fformat to avoid integer overflow issues.
17616 * editfns.c: Include <float.h> unconditionally, as it's everywhere
17617 now (part of C89). Include <verify.h>.
17618 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
17619 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
17620 (Fformat): Avoid the prepass trying to compute sizes; it was only
17621 approximate and thus did not catch overflow reliably. Instead, walk
17622 through the format just once, formatting and computing sizes as we go,
17623 checking for integer overflow at every step, and allocating a larger
17624 buffer as needed. Keep track separately whether the format is
17625 multibyte. Keep only the most-recently calculated precision, rather
17626 than them all. Record whether each argument has been converted to
17627 string. Use EMACS_INT, not int, for byte and char and arg counts.
17628 Support field widths and precisions larger than INT_MAX. Avoid
17629 sprintf's undefined behavior with conversion specifications such as %#d
17630 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
17631 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
17632 formatting out-of-range floating point numbers with int
17633 formats. (Bug#8668)
17635 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
17637 * data.c: Avoid integer truncation in expressions involving floats.
17638 * data.c: Include <intprops.h>.
17639 (arith_driver): When there's an integer overflow in an expression
17640 involving floating point, convert the integers to floating point
17641 so that the resulting value does not suffer from catastrophic
17642 integer truncation. For example, on a 64-bit host (* 4
17643 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
17644 Do not rely on undefined behavior after integer overflow.
17646 merge count_size_as_multibyte, parse_str_to_multibyte
17647 * character.c, character.h (count_size_as_multibyte):
17648 Rename from parse_str_to_multibyte; all uses changed.
17649 Check for integer overflow.
17650 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
17651 since it's now a duplicate of the other. This is more of
17652 a character than a buffer op, so better that it's in character.c.
17653 * fns.c, print.c: Adjust to above changes.
17655 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
17657 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
17659 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17661 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17662 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
17663 (x_clipboard_manager_save): Now static.
17664 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
17666 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17667 (crypto_hash_function): Now static.
17668 Fix pointer signedness problems. Avoid unnecessary initializations.
17670 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
17672 * termhooks.h (Vselection_alist): Make it terminal-local.
17674 * terminal.c (create_terminal): Initialize it.
17676 * xselect.c: Support for clipboard managers.
17677 (Vselection_alist): Move to termhooks.h as terminal-local var.
17678 (LOCAL_SELECTION): New macro.
17679 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
17680 (symbol_to_x_atom): Remove gratuitous arg.
17681 (x_handle_selection_request, lisp_data_to_selection_data)
17682 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
17683 (x_own_selection, x_get_local_selection, x_convert_selection):
17684 New arg, specifying work frame. Use terminal-local Vselection_alist.
17685 (some_frame_on_display): Delete unused function.
17686 (Fx_own_selection_internal, Fx_get_selection_internal)
17687 (Fx_disown_selection_internal, Fx_selection_owner_p)
17688 (Fx_selection_exists_p): New optional frame arg.
17689 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
17690 (x_handle_selection_clear): Don't treat other terminals with the
17691 same keyboard specially. Use the terminal-local Vselection_alist.
17692 (x_clear_frame_selections): Use Frun_hook_with_args.
17694 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
17696 * xterm.h: Add support for those atoms.
17698 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
17700 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
17701 (converted_selections, conversion_fail_tag): New global variables.
17702 (x_selection_request_lisp_error): Free the above.
17703 (x_get_local_selection): Remove unnecessary code.
17704 (x_reply_selection_request): Args changed; handle arbitrary array
17705 of converted selections stored in converted_selections.
17706 Separate the XChangeProperty and SelectionNotify steps.
17707 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
17708 (x_convert_selection): New function.
17709 (x_handle_selection_event): Simplify.
17710 (x_get_foreign_selection): Don't ignore incoming requests while
17711 waiting for an answer; this will fail when we implement
17712 SAVE_TARGETS, and seems unnecessary anyway.
17713 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
17714 (Vx_sent_selection_functions): Doc fix.
17716 2011-05-26 Leo Liu <sdl.web@gmail.com>
17718 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
17720 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17722 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
17724 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
17725 for fringe update if it has periodic bitmap.
17726 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
17727 and fringe_bitmap_periodic_p.
17729 * fringe.c (get_fringe_bitmap_data): New function.
17730 (draw_fringe_bitmap_1, update_window_fringes): Use it.
17731 (update_window_fringes): Record periodicity of fringe bitmap in glyph
17732 row. Mark glyph row for fringe update if periodicity changed.
17734 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
17735 for fringe update unless it has periodic bitmap.
17737 2011-05-25 Kenichi Handa <handa@m17n.org>

17756 Remove macros that are defined and never used.
17757 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
17759 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17761 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
17762 (Fx_get_selection_internal): Minor cleanup.

17788 report_file_error introduced by the change from 2011-05-07.
17790 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
17792 * systime.h (Time): Define only if emacs is defined.
17793 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
17794 where the include path doesn't have X11/X.h by default. See
17795 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
17797 2011-05-20 Kenichi Handa <handa@m17n.org>
17799 * composite.c (find_automatic_composition): Fix previous change.
17801 2011-05-20 Glenn Morris <rgm@gnu.org>

17811 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
17812 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
17813 (lisp): Set the order to that of loadup.el.
17814 (shortlisp): Make it a copy of $lisp.
17815 (SOME_MACHINE_LISP): Remove.
17816 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
17817 Use just $shortlisp, not $SOME_MACHINE_LISP too.
17819 2011-05-18 Kenichi Handa <handa@m17n.org>
17821 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
17822 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
17823 (find_automatic_composition): Mostly rewrite for efficiency.
17825 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
17827 * makefile.w32-in: Update dependencies.
17829 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
17831 * menu.c: Include limits.h (fixes the MS-Windows build broken by
17832 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
17834 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
17836 Fix some integer overflow issues, such as string length overflow.
17838 * insdel.c (count_size_as_multibyte): Check for string overflow.
17840 * character.c (lisp_string_width): Check for string overflow.
17841 Use EMACS_INT, not int, for string indexes and lengths; in
17842 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
17843 the resulting string length overflows an EMACS_INT; instead,
17844 report a string overflow if no precision given. When checking for
17845 precision exhaustion, use a check that cannot possibly have
17846 integer overflow. (Bug#8675)
17847 * character.h (lisp_string_width): Adjust to new signature.
17849 * alloc.c (string_overflow): New function.
17850 (Fmake_string): Use it. This doesn't change behavior, but saves
17851 a few bytes and will simplify future changes.
17852 * character.c (string_escape_byte8): Likewise.
17853 * lisp.h (string_overflow): New decl.
17855 Fixups, following up to the user-interface timestamp change.
17856 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
17857 for UI timestamps, instead of unsigned long.
17858 * msdos.c (mouse_get_pos): Likewise.
17859 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
17860 * w32gui.h (Time): Define by including "systime.h" rather than by
17861 declaring it ourselves. (Bug#8664)
17863 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
17864 * image.c (clear_image_cache): Likewise.
17866 * term.c (term_mouse_position): Don't assume time_t wraparound.
17868 Be more systematic about user-interface timestamps.
17869 Before, the code sometimes used 'Time', sometimes 'unsigned long',
17870 and sometimes 'EMACS_UINT', to represent these timestamps.
17871 This change causes it to use 'Time' uniformly, as that's what X uses.
17872 This makes the code easier to follow, and makes it easier to catch
17873 integer overflow bugs such as Bug#8664.
17874 * frame.c (Fmouse_position, Fmouse_pixel_position):
17875 Use Time, not unsigned long, for user-interface timestamps.
17876 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
17877 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
17878 * keyboard.h (last_event_timestamp): Likewise.
17879 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
17880 * menu.h (xmenu_show): Likewise.
17881 * term.c (term_mouse_position): Likewise.
17882 * termhooks.h (struct input_event.timestamp): Likewise.
17883 (struct terminal.mouse_position_hook): Likewise.
17884 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
17885 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
17886 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
17887 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
17888 what it was before.
17889 * menu.h, termhooks.h: Include "systime.h", for Time.
17891 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
17892 Don't assume that the difference between two unsigned long values
17893 can fit into an integer. At this point, we know button_down_time
17894 <= event->timestamp, so the difference must be nonnegative, so
17895 there's no need to cast the result if double-click-time is
17896 nonnegative, as it should be; check that it's nonnegative, just in
17897 case. This bug is triggered when events are more than 2**31 ms
17898 apart (about 25 days). (Bug#8664)
17900 * xselect.c (last_event_timestamp): Remove duplicate decl.
17901 (x_own_selection): Remove needless cast to unsigned long.
17903 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
17904 that always fit in int. Use a sentinel instead of a counter, to
17905 avoid a temp and to allay GCC's concerns about possible int overflow.
17906 * frame.h (struct frame): Use int for menu_bar_items_used
17907 instead of EMACS_INT, since it always fits in int.
17909 * menu.c (grow_menu_items): Check for int overflow.
17911 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
17913 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
17914 Before, the code was not consistent. These values cannot exceed
17915 2**31 - 1 so there's no need to make them unsigned.
17916 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
17917 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
17918 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
17920 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
17922 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
17923 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
17924 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
17925 presumably because the widths might not match.
17927 * window.c (size_window): Avoid needless test at loop start.
17929 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
17931 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
17933 2011-05-12 Drew Adams <drew.adams@oracle.com>
17935 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
17937 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17939 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
17940 `width' to `bar_area_x' and `bar_area_width', respectively.
17941 (x_scroll_run): Take account of fringe background extension.
17943 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
17944 Rename local vars `left' and `width' to `bar_area_x' and
17945 `bar_area_width', respectively.
17946 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
17947 background extension.
17949 2011-05-10 Jim Meyering <meyering@redhat.com>
17951 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
17953 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
17955 * image.c (Finit_image_library): Return t for built-in image types,
17956 like pbm and xbm. (Bug#8640)
17958 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
17960 * w32menu.c (set_frame_menubar): Fix submenu allocation.
17962 2011-05-07 Eli Zaretskii <eliz@gnu.org>
17964 * w32console.c (Fset_screen_color): Doc fix.
17965 (Fget_screen_color): New function.
17966 (syms_of_ntterm): Defsubr it.
17968 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
17969 unlink the temporary file if Fcall_process didn't create it in the
17971 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
17972 child process will be redirected to a file specified with `:file'.
17973 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
17974 cue to call_process_cleanup not to close that handle.
17976 2011-05-07 Ben Key <bkey76@gmail.com>
17978 * makefile.w32-in: The bootstrap-temacs rule now makes use of
17979 one of two shell specific rules, either bootstrap-temacs-CMD or
17980 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
17981 to the previous implementation of the bootstrap-temacs rule.
17982 The bootstrap-temacs-CMD rule is similar to the previous
17983 implementation of the bootstrap-temacs rule except that it
17984 makes use of the ESC_CFLAGS variable instead of the CFLAGS
17987 These changes, along with some changes to nt/configure.bat,
17988 nt/gmake.defs, and nt/nmake.defs, are required to extend my
17989 earlier fix to add support for --cflags and --ldflags options
17990 that include quotes so that it works whether make uses cmd or
17993 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
17995 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
17996 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
17998 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
17999 a string. Handle both cases.
18000 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
18001 (Fdbus_register_method): Use Qinvalid_function.
18003 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18005 * makefile.w32-in: Update dependencies.
18006 (LISP_H): Add inttypes.h and stdin.h.
18007 (PROCESS_H): Add unistd.h.
18009 2011-05-06 Eli Zaretskii <eliz@gnu.org>
18011 * lread.c: Include limits.h (fixes the MS-Windows build broken by
18012 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
18014 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
18016 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
18018 * term.c (vfatal): Remove stray call to va_end.
18019 It's not needed and the C Standard doesn't allow it here anyway.
18021 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
18022 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
18024 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
18027 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
18029 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
18031 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
18033 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
18035 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
18037 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
18038 * charset.c (Fdefine_charset_internal): Don't initialize
18039 charset.code_space[15]. The value was garbage, on hosts with
18040 32-bit int (Bug#8600).
18042 * lread.c (read_integer): Be more consistent with string-to-number.
18043 Use string_to_number to do the actual conversion; this avoids
18044 rounding errors and fixes some other screwups. Without this fix,
18045 for example, #x1fffffffffffffff was misread as -2305843009213693952.
18046 (digit_to_number): Move earlier, for benefit of read_integer.
18047 Return -1 if the digit is out of range for the base, -2 if it is
18048 not a digit in any supported base. (Bug#8602)
18050 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
18052 * dispnew.c (scrolling_window): Return 1 if we scrolled,
18053 to match comment at start of function. This also removes a
18054 GCC warning about overflow in a 32+64-bit port.
18056 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
18058 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
18059 Reported by Stefan Monnier in
18060 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
18061 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18062 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
18064 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
18065 (EMACS_UINTPTR): Likewise, with uintptr_t.
18067 * lisp.h: Prefer 64-bit EMACS_INT if available.
18068 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
18069 on 32-bit hosts that have 64-bit int, so that they can access
18071 However, temporarily disable this change unless the temporary
18072 symbol WIDE_EMACS_INT is defined.
18074 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
18076 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
18077 This removes an assumption that EMACS_INT and long are the same
18078 width as pointers. The assumption is true for Emacs porting targets
18079 now, but we want to make other targets possible.
18080 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
18081 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
18082 In the rest of the code, change types of integers that hold casted
18083 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
18084 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
18085 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
18086 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
18087 No need to cast type when ORing.
18088 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
18089 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
18090 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
18091 assume EMACS_INT is the same width as char *.
18092 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
18093 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
18094 Remove no-longer-needed casts.
18095 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
18096 (xg_tool_bar_help_callback, xg_make_tool_item):
18097 Use EMACS_INTPTR to hold an integer
18098 that will be cast to void *; this can avoid a GCC warning
18099 if EMACS_INT is not the same width as void *.
18100 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
18101 * xdisp.c (display_echo_area_1, resize_mini_window_1):
18102 (current_message_1, set_message_1):
18103 Use a local to convert to proper width without a cast.
18104 * xmenu.c (dialog_selection_callback): Likewise.
18106 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
18107 Also, don't assume VALBITS / RAND_BITS is less than 5,
18108 and don't rely on undefined behavior when shifting a 1 left into
18110 * lisp.h (get_random): Change signature to match.
18112 * lread.c (hash_string): Use size_t, not int, for hash computation.
18113 Normally we prefer signed values; but hashing is special, because
18114 it's better to use unsigned division on hash table sizes so that
18115 the remainder is nonnegative. Also, size_t is the natural width
18116 for hashing into memory. The previous code used 'int', which doesn't
18117 retain enough info to hash well into very large tables.
18118 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
18120 * dbusbind.c: Don't possibly lose pointer info when converting.
18121 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18122 Use XPNTR rather than XHASH, so that the high-order bits of
18123 the pointer aren't lost when converting through void *.
18125 * eval.c (Fautoload): Don't double-shift a pointer.
18127 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
18129 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18131 * gnutls.c (DEF_GNUTLS_FN):
18132 * image.c (DEF_IMGLIB_FN): Make function pointers static.
18134 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
18136 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
18139 2011-05-05 Eli Zaretskii <eliz@gnu.org>
18141 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
18142 New version that can reserve upto 2GB of heap space.
18144 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
18146 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
18148 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
18150 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
18151 `gnutls_certificate_set_x509_key_file'.
18153 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
18155 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
18156 Update dependencies.
18158 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18160 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
18161 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
18162 Remove unused parameter `fildes'.
18163 * process.c (read_process_output, send_process): Don't pass it.
18165 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18167 Fix previous change: the library cache is defined in w32.c.
18168 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
18169 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
18171 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18173 Implement dynamic loading of GnuTLS on Windows.
18175 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
18176 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
18177 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18180 * gnutls.c (Qgnutls_dll): Define.
18181 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
18182 (gnutls_*): Declare function pointers.
18183 (init_gnutls_functions): New function to initialize function pointers.
18184 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
18185 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
18186 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18187 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
18188 (emacs_gnutls_write, emacs_gnutls_read)
18189 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
18190 (Fgnutls_available_p): New function.
18191 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
18192 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
18193 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
18195 * image.c: Include w32.h.
18196 (Vimage_type_cache): Delete.
18197 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
18198 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
18199 (w32_delayed_load): Move to w32.c.
18201 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
18203 * w32.c (QCloaded_from, Vlibrary_cache): Define.
18204 (w32_delayed_load): Move from image.c. When loading a library, record
18205 its filename in the :loaded-from property of the library id.
18206 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
18207 Initialize and staticpro them.
18208 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
18210 * process.c: Include lisp.h before w32.h, not after.
18211 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
18212 instead of gnutls_record_check_pending.
18214 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
18216 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
18218 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
18219 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
18222 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
18224 * xterm.c (x_set_frame_alpha): Do not set property on anything
18225 else than FRAME_X_OUTER_WINDOW (Bug#8608).
18227 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
18229 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)

18264 rather than `XVECTOR (FOO)->size'.
18266 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
18267 inttypes.h, as a gnulib replacement is used if it not available in
18270 2011-04-21 Eli Zaretskii <eliz@gnu.org>
18272 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
18273 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
18274 of MOST_POSITIVE_FIXNUM. (Bug#8528)
18276 * coding.c (coding_alloc_by_realloc): Error out if destination
18277 will grow beyond MOST_POSITIVE_FIXNUM.
18278 (decode_coding_emacs_mule): Abort if there isn't enough place in
18279 charbuf for the composition carryover bytes. Reserve an extra
18280 space for up to 2 characters produced in a loop.
18281 (decode_coding_iso_2022): Abort if there isn't enough place in
18282 charbuf for the composition carryover bytes.
18284 2011-04-21 Eli Zaretskii <eliz@gnu.org>
18286 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
18287 aborting when %lld or %lll format is passed.
18288 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
18289 %llo or %llx format is passed. (Bug#8545)
18291 * window.c (window_scroll_line_based): Use a marker instead of
18292 simple variables to record original value of point. (Bug#7952)
18294 * doprnt.c (doprnt): Fix the case where a multibyte sequence
18295 produced by %s or %c overflows available buffer space. (Bug#8545)
18297 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
18299 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
18300 (SIZE_MAX): Move defn after all includes, as they might #define it.
18302 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18304 * w32.c (init_environment): Warn about defaulting HOME to C:\.
18306 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18308 * keyboard.c (Qdelayed_warnings_hook): Define.
18309 (command_loop_1): Run `delayed-warnings-hook'
18310 if Vdelayed_warnings_list is non-nil.
18311 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
18312 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
18314 2011-04-28 Eli Zaretskii <eliz@gnu.org>
18316 * doprnt.c (doprnt): Don't return value smaller than the buffer
18317 size if the message was truncated. (Bug#8545).
18319 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18321 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
18322 (Fx_window_property): #if-0 the whole functions, not just the bodies.
18324 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18326 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
18328 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
18330 * makefile.w32-in: Update dependencies.
18332 2011-04-27 Eli Zaretskii <eliz@gnu.org>
18334 Improve `doprnt' and its usage. (Bug#8545)
18335 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
18336 `format_end'. Remove support for %l as a conversion specifier.
18337 Don't use xrealloc. Improve diagnostics when the %l size modifier
18338 is used. Update the commentary.
18340 * eval.c (verror): Simplify calculation of size_t.
18342 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
18345 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
18347 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
18350 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18352 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
18353 This makes this file independent of the recent pseudovector change.
18355 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
18357 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
18359 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
18360 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
18361 Remove unused local.
18362 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
18364 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
18365 GCC 4.6.0 optimizes based on type-based alias analysis.
18366 For example, if b is of type struct buffer * and v of type struct
18367 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
18368 != &v->size, and therefore "v->size = 1; b->size = 2; return
18369 v->size;" must therefore return 1. This assumption is incorrect
18370 for Emacs, since it type-puns struct Lisp_Vector * with many other
18371 types. To fix this problem, this patch adds a new type struct
18372 vectorlike_header that documents the constraints on layout of vectors
18373 and pseudovectors, and helps optimizing compilers not get fooled
18374 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
18375 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
18376 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
18378 (XSETPVECTYPE): Rewrite in terms of new macro.
18379 (XSETPVECTYPESIZE): New macro, specifying both type and size.
18380 This is a bit clearer, and further avoids the possibility of
18381 undesirable aliasing.
18382 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
18383 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
18384 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
18385 since Lisp_Subr is a special case (no "next" field).
18386 (ASIZE): Now uses header.size rather than size.
18387 All previous uses of XVECTOR (foo)->size replaced to use this macro,
18388 to avoid the hassle of writing XVECTOR (foo)->header.size.
18389 (struct vectorlike_header): New type.
18390 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
18391 object, to help avoid aliasing.
18392 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
18393 (SUBRP): Likewise, since Lisp_Subr is a special case.
18394 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
18395 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
18396 (struct Lisp_Hash_Table): Combine first two members into a single
18397 struct vectorlike_header member. All uses of "size" and "next" members
18398 changed to be "header.size" and "header.next".
18399 * buffer.h (struct buffer): Likewise.
18400 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
18401 * frame.h (struct frame): Likewise.
18402 * process.h (struct Lisp_Process): Likewise.
18403 * termhooks.h (struct terminal): Likewise.
18404 * window.c (struct save_window_data, struct saved_window): Likewise.
18405 * window.h (struct window): Likewise.
18406 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
18407 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
18408 * buffer.c (init_buffer_once): Likewise.
18409 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
18411 * process.c (Fformat_network_address): Use local var for size,
18414 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
18416 Make the Lisp reader and string-to-float more consistent (Bug#8525)
18417 * data.c (atof): Remove decl; no longer used or needed.
18418 (digit_to_number): Move to lread.c.
18419 (Fstring_to_number): Use new string_to_number function, to be
18420 consistent with how the Lisp reader treats infinities and NaNs.
18421 Do not assume that floating-point numbers represent EMACS_INT
18422 without losing information; this is not true on most 64-bit hosts.
18423 Avoid double-rounding errors, by insisting on integers when
18424 parsing non-base-10 numbers, as the documentation specifies.
18425 * lisp.h (string_to_number): New decl, replacing ...
18426 (isfloat_string): Remove.
18427 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
18428 (read1): Do not accept +. and -. as integers; this
18429 appears to have been a coding error. Similarly, do not accept
18430 strings like +-1e0 as floating point numbers. Do not report
18431 overflow for integer overflows unless the base is not 10 which
18432 means we have no simple and reliable way to continue.
18433 Break out the floating-point parsing into a new
18434 function string_to_number, so that Fstring_to_number parses
18435 floating point numbers consistently with the Lisp reader.
18436 (digit_to_number): Move here from data.c. Make it static inline.
18437 (E_CHAR, EXP_INT): Remove, replacing with ...
18438 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
18439 (string_to_number): New function, replacing isfloat_string.
18440 This function checks for valid syntax and produces the resulting
18441 Lisp float number too. Rework it so that string-to-number
18442 no longer mishandles examples like "1.0e+". Use strtoumax,
18443 so that overflow for non-base-10 numbers is reported only when
18444 there's no portable and simple way to convert to floating point.
18446 * textprop.c (set_text_properties_1): Rewrite for clarity,
18447 and to avoid GCC warning about integer overflow.
18449 * intervals.h (struct interval): Use EMACS_INT for members
18450 where EMACS_UINT might cause problems. See
18451 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
18452 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
18453 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
18455 (offset_intervals): Tell GCC not to worry about length overflow
18456 when negating a negative length.
18458 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
18459 (overrun_check_free): Likewise.
18461 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
18462 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
18465 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18466 (gnutls_make_error): Rename local to avoid shadowing.
18467 (gnutls_emacs_global_deinit): ifdef out; not used.
18468 (Fgnutls_boot): Use const for pointer to readonly storage.
18469 Comment out unused local. Fix pointer signedness problems.
18471 * lread.c (openp): Don't stuff size_t into an 'int'.
18472 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
18473 about possible signed overflow.
18475 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18476 (GDK_KEY_g): Don't define if already defined.
18477 (xg_prepare_tooltip): Avoid pointer signedness problem.
18478 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
18480 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
18481 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
18483 * xfns.c (Fx_window_property): Simplify a bit,
18484 to make a bit faster and to avoid GCC 4.6.0 warning.
18485 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
18487 * fns.c (internal_equal): Don't assume size_t fits in int.
18489 * alloc.c (compact_small_strings): Tighten assertion a little.
18491 Replace pEd with more-general pI, and fix some printf arg casts.
18492 * lisp.h (pI): New macro, generalizing old pEd macro to other
18493 conversion specifiers. For example, use "...%"pI"d..." rather
18494 than "...%"pEd"...".
18495 (pEd): Remove. All uses replaced with similar uses of pI.
18496 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
18497 * alloc.c (check_pure_size): Don't overflow by converting size to int.
18498 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
18499 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
18500 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
18501 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
18502 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
18504 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
18505 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
18506 * print.c (safe_debug_print, print_object): Likewise.
18507 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
18509 Use pI instead of if-then-else-abort. Use %p to avoid casts,
18510 avoiding the 0 flag, which is not portable.
18511 * process.c (Fmake_network_process): Use pI to avoid cast.
18512 * region-cache.c (pp_cache): Likewise.
18513 * xdisp.c (decode_mode_spec): Likewise.
18514 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
18515 behavior on 64-bit hosts with printf arg.
18516 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
18517 (x_stop_queuing_selection_requests): Likewise.
18518 (x_get_window_property): Don't truncate byte count to an 'int'
18521 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
18522 here, since it parses constructs like leading '-' and spaces,
18523 which are not wanted; and it overflows with large numbers.
18524 Instead, simply match F[0-9]+, which is what is wanted anyway.
18526 * alloc.c: Remove unportable assumptions about struct layout.
18527 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
18528 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
18529 (allocate_vectorlike, make_pure_vector): Use the new macros,
18530 plus offsetof, to remove unportable assumptions about struct layout.
18531 These assumptions hold on all porting targets that I know of, but
18532 they are not guaranteed, they're easy to remove, and removing them
18533 makes further changes easier.
18535 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
18536 This doesn't fix a bug but makes the code clearer.
18537 (string_overrun_cookie): Now const. Use initializers that
18538 don't formally overflow signed char, to avoid warnings.
18539 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
18540 can cause Emacs to crash when string overrun checking is enabled.
18541 (allocate_buffer): Don't assume sizeof (struct buffer) is a
18542 multiple of sizeof (EMACS_INT); it need not be, if
18543 alignof(EMACS_INT) < sizeof (EMACS_INT).
18544 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
18546 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

18550 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
18552 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
18553 supposed to be handshaking. (Bug#8556)
18554 Reported by Paul Eggert <eggert@cs.ucla.edu>.

18561 (handle_user_signal): Break into debugger when debug-on-event
18562 matches the current signal symbol.
18564 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
18566 * alloc.c (check_sblock, check_string_bytes)
18567 (check_string_free_list): Convert to standard C.
18569 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
18571 * w32.c (emacs_gnutls_push): Fix typo.
18573 2011-04-25 Eli Zaretskii <eliz@gnu.org>
18575 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
18576 "cast to pointer from integer of different size".
18578 Improve doprnt and its use in verror. (Bug#8545)
18579 * doprnt.c (doprnt): Document the set of format control sequences
18580 supported by the function. Use SAFE_ALLOCA instead of always
18583 * eval.c (verror): Don't limit the buffer size at size_max-1, that
18584 is one byte too soon. Don't use xrealloc; instead xfree and
18587 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
18589 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
18592 * gnutls.c: Renamed global_initialized to
18593 gnutls_global_initialized. Added internals for the
18594 :verify-hostname-error, :verify-error, and :verify-flags
18595 parameters of `gnutls-boot' and documented those parameters in the
18596 docstring. Start callback support.
18597 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
18598 unless a fatal error occurred. Call gnutls_alert_send_appropriate
18599 on error. Return error code.
18600 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
18601 (emacs_gnutls_read): Likewise.
18602 (Fgnutls_boot): Return handshake error code.
18603 (emacs_gnutls_handle_error): New function.
18604 (wsaerror_to_errno): Likewise.

18607 (emacs_gnutls_push): Likewise.
18609 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
18610 (emacs_gnutls_push): Likewise.
18612 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
18614 * process.c (wait_reading_process_output): Check if GnuTLS
18615 buffered some data internally if no FDs are set for TLS
18618 * makefile.w32-in (OBJ2): Add gnutls.$(O).
18619 (LIBS): Link to USER_LIBS.

18624 * xdisp.c (handle_single_display_spec): Rename the
18625 display_replaced_before_p argument into display_replaced_p, to
18626 make it consistent with the commentary. Fix typos in the
18629 * textprop.c (syms_of_textprop): Remove dead code.

18641 to changes in oldXMenu/XMenu.h from 2011-04-16.
18642 (struct XMenu): Declare `help_text' `const char **'.

18659 changes in globals.h immediately force recompilation.
18660 (TAGS): Depend on $(CURDIR)/m/intel386.h and
18661 $(CURDIR)/s/ms-w32.h.

18671 * doprnt.c: Include limits.h.
18672 (SIZE_MAX): New macro.
18673 (doprnt): Return a size_t value. 2nd arg is now size_t.
18674 Many local variables are now size_t instead of int or unsigned.
18675 Improve overflow protection. Support `l' modifier for integer
18676 conversions. Support %l conversion. Don't assume an EMACS_INT
18677 argument for integer conversions and for %c.

18701 * character.c (char_string): Use %x to display the (unsigned)
18702 codepoint of an invalid character, to avoid displaying a bogus
18705 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
18706 `error', not SYMBOL_NAME itself.
18708 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
18709 character arguments to `error'.
18711 * charset.c (check_iso_charset_parameter): Fix incorrect argument
18712 to `error' in error message about FINAL_CHAR argument. Make sure
18713 FINAL_CHAR is a character, and use %c when it is passed as
18714 argument to `error'.
18716 2011-04-23 Eli Zaretskii <eliz@gnu.org>
18718 * s/ms-w32.h (localtime): Redirect to sys_localtime.

18834 out-of-range initializers by using, for example, '\xab' rather
18837 * xgselect.c (xgselect_initialize): Check vs interface
18838 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).

18903 * nsfont.m: Fixed bugs in ns_get_family and
18904 ns_descriptor_to_entity that were caused by using free to
18905 deallocate memory blocks that were allocated by xmalloc (via
18906 xstrdup). This caused Emacs to crash when compiled with

18924 Emacs source code has been audited now.
18925 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
18926 (emacs_read, emacs_write): Use it.
18927 * process.c (send_process): Adjust to the new signatures of
18928 emacs_write and emacs_gnutls_write. Do not attempt to store
18929 a byte offset into an 'int'; it might overflow.
18930 See http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00483.html

19152 * editfns.c, lisp.h (get_operating_system_release): Remove.
19153 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
19154 worth the hassle of breaking this out.
19156 * xterm.c: Make symbols static if they're not exported.
19157 (x_raise_frame, x_lower_frame, x_wm_set_window_state):

19269 * atimer.h (run_all_atimers): Remove; not exported.
19271 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
19272 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
19273 was inaccessible from Lisp.
19274 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
19275 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
19277 alloc.c: Import and export fewer symbols, and remove unused items.
19278 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
19280 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
19281 it's not optimized away by whole-program optimization.

19294 (mark_backtrace): Define only if BYTE_MARK_STACK.
19295 * xdisp.c (message_enable_multibyte): Now static.
19297 Declare Lisp_Object Q* variables to be 'static' if not exported.
19298 This makes it easier for human readers (and static analyzers)
19299 to see whether these variables are used from other modules.
19300 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
19301 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:

19311 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
19313 * lisp.h (DEFINE_FUNC): Make sname 'static'.
19315 Make Emacs functions such as Fatom 'static' by default.
19316 This makes it easier for human readers (and static analyzers)
19317 to see whether these functions can be called from other modules.
19318 DEFUN now defines a static function. To make the function external
19319 so that it can be used in other C modules, use the new macro DEFUE.
19320 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
19321 (Finit_image_library):
19322 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):

19324 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
19325 Remove decls, since these functions are now static.
19326 (Funintern, Fget_internal_run_time): New decls, since these functions
19327 were already external.
19329 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

19337 Mark functions with DEFUE instead of DEFUN,
19338 if they are used in other modules.
19339 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
19340 decls for now-static functions.
19341 * buffer.h (Fdelete_overlay): Remove decl.
19342 * callproc.c (Fgetenv_internal): Mark as internal.

19351 * image.c (Finit_image_library): New forward static decl.
19352 * insdel.c (Fcombine_after_change_execute): Make forward decl static.

19354 (Fremove_list_of_text_properties): Remove decls.
19355 * keyboard.c (Fthis_command_keys): Remove decl.
19356 (Fcommand_execute): New forward static decl.

19377 2011-04-13 Eli Zaretskii <eliz@gnu.org>
19379 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
19380 when at ZV. (Bug#8487)
19382 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
19384 * charset.c (Fclear_charset_maps): Use xfree instead of free.

19390 * xsettings.c (read_and_apply_settings): Likewise.
19392 * alloc.c (overrun_check_malloc, overrun_check_realloc)
19393 (overrun_check_free): Protoize.
19395 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
19397 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
19398 since callers should never pass a negative size.
19399 Change the signature to match that of plain 'read' and 'write'; see
19400 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
19401 * lisp.h: Update prototypes of emacs_write and emacs_read.
19403 2011-04-11 Eli Zaretskii <eliz@gnu.org>
19405 * xdisp.c (redisplay_window): Don't try to determine the character
19406 position of the scroll margin if the window start point w->startp
19407 is outside the buffer's accessible region. (Bug#8468)
19409 2011-04-10 Eli Zaretskii <eliz@gnu.org>
19411 Fix write-region and its subroutines for buffers > 2GB.
19412 * fileio.c (a_write, e_write): Modify declaration of arguments and
19413 local variables to support buffers larger than 2GB.
19414 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
19416 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
19417 argument, local variables, and return value.
19419 * lisp.h: Update prototypes of emacs_write and emacs_read.
19421 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
19423 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
19425 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
19427 Fix more problems found by GCC 4.6.0's static checks.
19429 * xdisp.c (vmessage): Use a better test for character truncation.
19431 * charset.c (load_charset_map): <, not <=, for optimization,
19432 and to avoid potential problems with integer overflow.
19433 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
19434 * casetab.c (set_identity, shuffle): Likewise.
19435 * editfns.c (Fformat): Likewise.
19436 * syntax.c (skip_chars): Likewise.
19438 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
19439 This also lets GCC 4.6.0 generate slightly better loop code.
19441 * callint.c (Fcall_interactively): <, not <=, for optimization.
19442 (Fcall_interactively): Count the number of arguments produced,
19443 not the number of arguments given. This is simpler and lets GCC
19444 4.6.0 generate slightly better code.
19446 * ftfont.c: Distingish more carefully between FcChar8 and char.
19447 The previous code passed unsigned char * to a functions like
19448 strlen and xstrcasecmp that expect char *, which does not
19449 conform to the C standard.
19450 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
19451 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
19452 char * when the C standard requires it.
19454 * keyboard.c (read_char): Remove unused var.
19456 * eval.c: Port to Windows vsnprintf (Bug#8435).
19457 Include <limits.h>.
19458 (SIZE_MAX): Define if the headers do not.
19459 (verror): Do not give up if vsnprintf returns a negative count.
19460 Instead, grow the buffer. This ports to Windows vsnprintf, which
19461 does not conform to C99. Problem reported by Eli Zaretskii.
19462 Also, simplify the allocation scheme, by avoiding the need for
19463 calling realloc, and removing the ALLOCATED variable.
19465 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
19467 Remove invocations of doprnt, as Emacs now uses vsnprintf.
19468 But keep the doprint source code for now, as we might revamp it
19469 and use it again (Bug#8435).
19470 * lisp.h (doprnt): Remove.
19471 * Makefile.in (base_obj): Remove doprnt.o.
19472 * deps.mk (doprnt.o): Remove.
19474 error: Print 32- and 64-bit integers portably (Bug#8435).
19475 Without this change, on typical 64-bit hosts error ("...%d...", N)
19476 was used to print both 32- and 64-bit integers N, which relied on
19477 undefined behavior.
19478 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
19479 * lisp.h (error, verror): Mark as printf-like functions.
19480 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
19481 Report overflow in size calculations when allocating printf buffer.
19482 Do not truncate output string at its first null byte.
19483 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
19484 Truncate the output at a character boundary, since vsnprintf does not
19486 * charset.c (check_iso_charset_parameter): Convert internal
19487 character to string before calling 'error', since %c now has the
19489 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
19490 overflow when computing char to be passed to 'error'. Do not
19491 pass Lisp_Object to 'error'; pass the integer instead.
19492 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
19493 formatted with plain %d.
19495 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
19497 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
19499 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
19501 * xterm.c (x_catch_errors): Remove duplicate declaration.
19503 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
19505 * xdisp.c, lisp.h (message_nolog): Remove; unused.
19507 2011-04-10 Jim Meyering <meyering@redhat.com>
19509 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
19510 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
19511 return ssize_t not "int", and use size_t as the buffer length.
19512 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
19513 * gnutls.h: Update declarations.
19514 * process.c (read_process_output): Use ssize_t, to match.
19515 (send_process): Likewise.
19517 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19519 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
19521 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19523 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
19524 Use unsigned char, to match FcChar8 type definition.
19526 * xterm.c (handle_one_xevent):
19527 * xmenu.c (create_and_show_popup_menu):
19528 * xselect.c (x_decline_selection_request)
19529 (x_reply_selection_request): Avoid type-punned deref of X events.
19531 2011-04-09 Eli Zaretskii <eliz@gnu.org>
19533 Fix some uses of `int' instead of EMACS_INT.
19534 * search.c (string_match_1, fast_string_match)
19535 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
19536 (scan_buffer, find_next_newline_no_quit)
19537 (find_before_next_newline, search_command, Freplace_match)
19538 (Fmatch_data): Make some `int' variables be EMACS_INT.
19540 * xdisp.c (display_count_lines): 3rd argument and return value now
19541 EMACS_INT. All callers changed.

19587 instead of using internal_with_output_to_temp_buffer.
19588 (Qhelp_form_show): New var.
19589 (syms_of_keyboard): Use DEFSYM macro.
19591 * print.c (internal_with_output_to_temp_buffer): Function deleted.

19604 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
19606 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
19608 Fix more problems found by GCC 4.6.0's static checks.
19610 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.

19614 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
19616 * xdisp.c (vmessage): Mark as a printf-like function.
19618 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.

19625 to system-supplied API.
19627 * eval.c (Fsignal): Remove excess argument to 'fatal'.
19629 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
19630 This avoids several warnings with gcc -Wstrict-overflow.
19631 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
19632 directly, rather than having caller test rule sign. This avoids
19633 some unnecessary tests.
19634 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
19635 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
19636 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
19638 * xfont.c (xfont_text_extents): Remove var that was set but not used.
19639 (xfont_open): Avoid unnecessary tests.
19641 * composite.c (composition_gstring_put_cache): Use unsigned integer.
19643 * composite.h, composite.c (composition_gstring_put_cache):
19644 Use EMACS_INT, not int, for length.
19646 * composite.h (COMPOSITION_DECODE_REFS): New macro,
19647 breaking out part of COMPOSITION_DECODE_RULE.
19648 (COMPOSITION_DECODE_RULE): Use it.
19649 * composite.c (get_composition_id): Remove unused local vars,
19650 by using the new macro.
19652 * textprop.c (set_text_properties_1): Change while to do-while,
19653 since the condition is always true at first.
19655 * intervals.c (graft_intervals_into_buffer): Mark var as used.
19656 (interval_deletion_adjustment): Return unsigned value.
19659 * process.c (list_processes_1, create_pty, read_process_output):
19660 (exec_sentinel): Remove vars that were set but not used.
19661 (create_pty): Remove unnecessary "volatile"s.
19662 (Fnetwork_interface_info): Avoid possibility of int overflow.

19675 * print.c (print_error_message): Avoid int overflow.
19677 * font.c (font_list_entities): Redo for clarity,
19678 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
19680 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
19681 (font_score): Avoid potential overflow in diff calculation.
19683 * fns.c (substring_both): Remove var that is set but not used.
19684 (sxhash): Redo loop for clarity and to avoid wraparound warning.
19686 * eval.c (funcall_lambda): Rename local to avoid shadowing.
19688 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
19689 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
19690 can always succeed if overflow has undefined behavior.
19692 * search.c (boyer_moore, wordify): Remove vars set but not used.
19693 (wordify): Omit three unnecessary tests.
19695 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
19696 All callers changed. This avoids the need for an unused var.

19700 * dired.c (file_name_completion): Remove var that is set but not used.
19702 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
19704 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
19705 (Finsert_file_contents): Remove unnecessary code checking fd.
19707 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
19708 Check for integer overflow on size calculations.
19710 * buffer.c (Fprevious_overlay_change): Remove var that is set
19713 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
19714 Remove vars that are set but not used.
19715 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
19716 (timer_check_2): Mark vars as initialized.
19718 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
19720 * image.c (lookup_image): Remove var that is set but not used.
19721 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
19723 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
19724 that are set but not used.
19726 * xfns.c (make_invisible_cursor): Don't return garbage
19727 if XCreateBitmapFromData fails (Bug#8410).
19729 * xselect.c (x_get_local_selection, x_handle_property_notify):
19730 Remove vars that are set but not used.
19732 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
19733 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
19735 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
19736 Remove var that is set but not used.
19737 (scroll_bar_windows_size): Now size_t, not int.
19738 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
19739 Check for overflow.
19741 * xfaces.c (realize_named_face): Remove vars that are set but not used.
19742 (map_tty_color) [!defined MSDOS]: Likewise.
19744 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
19746 * coding.c: Remove vars that are set but not used.
19747 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
19748 All callers changed.
19749 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
19750 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
19751 (decode_coding_charset): Remove vars that are set but not used.
19753 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
19754 that is set but not used.
19756 * print.c (print_object): Remove var that is set but not used.
19758 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
19759 The gnulib version avoids calling malloc in the usual case,
19760 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
19761 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
19762 * filelock.c (current_lock_owner): Likewise.
19763 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
19764 * sysdep.c: Include allocator.h, careadlinkat.h.
19765 (emacs_no_realloc_allocator): New static constant.
19766 (emacs_readlink): New function.
19767 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
19768 ../lib/careadlinkat.h.
19770 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
19772 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
19773 first non-nil return value).
19775 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
19777 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
19778 if not defined (Bug#8403).
19780 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
19782 * xdisp.c (display_count_lines): Remove parameter `start',
19783 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
19784 (get_char_face_and_encoding): Remove parameter `multibyte_p',
19785 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

19787 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
19788 and thereabouts. All callers changed.
19789 (get_per_char_metric): Remove parameter `f', unused since
19790 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
19792 2011-04-02 Jim Meyering <meyering@redhat.com>
19794 do not dereference NULL upon failed strdup
19795 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
19796 (ns_get_family): Likewise.
19798 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
19800 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
19802 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
19804 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
19807 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
19809 Add lexical binding.
19811 * window.c (Ftemp_output_buffer_show): New fun.
19812 (Fsave_window_excursion):
19813 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
19815 * lread.c (lisp_file_lexically_bound_p): New function.

19817 (readevalloop): Remove `evalfun' arg.
19818 Bind Qinternal_interpreter_environment.
19819 (Feval_buffer): Bind Qlexical_binding.
19820 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
19822 (syms_of_lread): Declare `lexical-binding'.
19824 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
19826 * keyboard.c (eval_dyn): New fun.
19827 (menu_item_eval_property): Use it.
19829 * image.c (parse_image_spec): Use Ffunctionp.
19831 * fns.c (concat, mapcar1): Accept byte-code-functions.
19833 * eval.c (Fsetq): Handle lexical vars.
19834 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
19835 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
19836 (FletX, Flet): Obey lexical binding.
19837 (Fcommandp): Handle closures.
19838 (Feval): New `lexical' arg.
19839 (eval_sub): New function extracted from Feval. Use it almost
19840 everywhere where Feval was used. Look up vars in lexical env.
19842 (Ffunctionp): Move from subr.el.
19843 (Ffuncall): Handle closures.
19844 (apply_lambda): Remove `eval_flags'.
19845 (funcall_lambda): Handle closures and new byte-code-functions.
19846 (Fspecial_variable_p): New function.
19847 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
19848 but without exporting it to Lisp.
19850 * doc.c (Fdocumentation, store_function_docstring):
19851 * data.c (Finteractive_form): Handle closures.
19853 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
19856 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
19858 (exec_byte_code): New function extracted from Fbyte_code to handle new
19859 calling convention for byte-code-functions. Add new byte-codes.
19861 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
19863 * alloc.c (Fmake_symbol): Init new `declared_special' field.
19865 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
19867 * xdisp.c (redisplay_internal): Fix prototype.
19869 2011-03-31 Eli Zaretskii <eliz@gnu.org>
19871 * xdisp.c (SCROLL_LIMIT): New macro.
19872 (try_scrolling): Use it when setting scroll_limit.
19873 Limit scrolling to 100 screen lines.
19874 (redisplay_window): Even when falling back on "recentering",
19875 position point in the window according to scroll-conservatively,
19876 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
19878 (try_scrolling): When point is above the window, allow searching
19879 as far as scroll_max, or one screenful, to compute vertical
19880 distance from PT to the scroll margin position. This prevents
19881 try_scrolling from unnecessarily failing when
19882 scroll-conservatively is set to a value slightly larger than the
19883 window height. Clean up the case of PT below the margin at bottom
19884 of window: scroll_max can no longer be INT_MAX. When aggressive
19885 scrolling is in use, don't let point enter the opposite scroll
19886 margin as result of the scroll.
19887 (syms_of_xdisp) <scroll-conservatively>: Document the
19888 threshold of 100 lines for never-recentering scrolling.
19890 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
19892 * dispextern.h (move_it_by_lines):
19893 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
19894 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
19895 (message_log_check_duplicate): Remove parameters `prev_bol' and
19896 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
19897 (redisplay_internal): Remove parameter `preserve_echo_area',
19898 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
19900 * indent.c (Fvertical_motion):
19901 * window.c (window_scroll_pixel_based, Frecenter):
19902 Don't pass `need_y_p' to `move_it_by_lines'.
19904 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
19906 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
19907 steal a few bits to be more compact.
19908 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
19909 Remove unneeded casts.
19911 * bytecode.c (Fbyte_code): CAR and CDR can GC.
19913 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
19915 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
19916 binding" message (bug#7967).
19918 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
19920 Fix more problems found by GCC 4.6.0's static checks.
19922 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
19923 Remove unused local var.
19925 * editfns.c (Fmessage_box): Remove unused local var.
19927 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
19928 (note_mode_line_or_margin_highlight, note_mouse_highlight):
19929 Omit unused local vars.
19930 * window.c (shrink_windows): Omit unused local var.
19931 * menu.c (digest_single_submenu): Omit unused local var.
19932 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
19933 Omit unused local var.
19935 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
19936 Don't assume string length fits in int.
19937 (keyremap_step, read_key_sequence): Use size_t for sizes.
19938 (read_key_sequence): Don't check last_real_key_start redundantly.
19940 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
19941 instead of alloca (Bug#8344).
19943 * eval.c (Fbacktrace): Don't assume nargs fits in int.
19944 (Fbacktrace_frame): Don't assume nframes fits in int.
19946 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
19948 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
19951 * term.c (produce_glyphless_glyph): Remove unnecessary test.
19953 * cm.c (calccost): Turn while-do into do-while, for clarity.
19955 * keyboard.c (syms_of_keyboard): Use the same style as later
19956 in this function when indexing through an array. This also
19957 works around GCC bug 48267.
19959 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
19961 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
19963 * chartab.c (sub_char_table_ref_and_range): Redo for slight
19964 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
19966 * keyboard.c, keyboard.h (num_input_events): Now size_t.
19967 This avoids undefined behavior on integer overflow, and is a bit
19968 more convenient anyway since it is compared to a size_t variable.
19970 Variadic C functions now count arguments with size_t, not int.
19971 This avoids an unnecessary limitation on 64-bit machines, which
19972 caused (substring ...) to crash on large vectors (Bug#8344).
19973 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
19974 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
19975 All variadic functions and their callers changed accordingly.

19982 * fns.c (concat): Likewise.
19983 * frame.c (x_set_frame_parameters): Likewise.
19984 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
19985 0 if not found, not -1. All callers changed.
19987 * alloc.c (garbage_collect): Don't assume stack size fits in int.
19988 (stack_copy_size): Now size_t, not int.
19989 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
19991 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
19993 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
19994 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
19995 All callers changed.
19997 * lisp.h (multibyte_char_to_unibyte):
19998 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',

20202 Fix more problems found by GCC 4.5.2's static checks.
20204 * coding.c (encode_coding_raw_text): Avoid unnecessary test
20205 the first time through the loop, since we know p0 < p1 then.
20206 This also avoids a gcc -Wstrict-overflow warning.
20208 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
20209 leading to a memory leak, possible in functions like
20210 load_charset_map_from_file that can allocate an unbounded number
20211 of objects (Bug#8318).
20213 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
20214 that could (at least in theory) be that large.
20216 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
20217 This is less likely to overflow, and avoids undefined behavior if
20218 overflow does occur. All callers changed. Use strtoul to scan

20236 * process.c (Fmake_network_process): Use socklen_t, not int,
20237 where POSIX says socklen_t is required in portable programs.
20238 This fixes a porting bug on hosts like 64-bit HP-UX, where
20239 socklen_t is wider than int (Bug#8277).
20240 (Fmake_network_process, server_accept_connection):
20241 (wait_reading_process_output, read_process_output):

20256 Include tparam.h instead, since it declares them.

20258 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
20259 * terminfo.c: Include tparam.h, to check interfaces.
20260 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
20261 (tparam): Adjust signature to match interface in tparam.h;
20262 this removes some undefined behavior. Check that outstring and len
20263 are zero, which they always are with Emacs.
20264 * tparam.h (PC, BC, UP): New extern decls.
20266 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
20267 (xftfont_open): Rename locals to avoid shadowing.

20285 (composition_update_it): Mark var as initialized.
20286 (find_automatic_composition): Mark vars as initialized,
20287 with a FIXME (Bug#8290).

20307 (alsa_choose_format): Remove unused local var.
20308 (wav_play): Initialize a variable to 0, to prevent undefined
20309 behavior (Bug#8278).
20311 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
20313 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
20315 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
20316 clobbering (Bug#8298).
20317 * sysdep.c (sys_subshell): Likewise.
20318 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
20320 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
20321 This should get cleaned up, so that child_setup has the
20322 same signature on all platforms.
20324 * callproc.c (call_process_cleanup): Now static.
20325 (relocate_fd): Rename locals to avoid shadowing.
20327 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
20329 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
20330 not to be necessary, and produces flickering.

20334 * config.in: Remove file.
20336 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

20381 Define only if needed.
20383 * unexelf.c (unexec): Name an expression,
20384 to avoid gcc -Wbad-function-cast warning.
20385 Use a different way to cause a compilation error if anyone uses
20386 n rather than nn, a way that does not involve shadowing.
20387 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
20389 * deps.mk (unexalpha.o): Remove; unused.

20452 * process.c (get_operating_system_release): Move decl to lisp.h.
20453 * xrdb.c (get_system_name): Likewise.
20454 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
20455 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
20456 some of which prompt warnings from gcc -Wbad-function-cast.
20457 (Fformat_time_string, Fencode_time, Finsert_char):
20458 (Ftranslate_region_internal, Fformat):
20459 Rename or remove local vars to avoid shadowing.

20485 (GC_STRING_CHARS): Remove; not used.
20486 (Fmemory_limit): Cast sbrk's returned value to char *.
20488 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
20489 avoids undefined behavior in theory.
20491 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
20493 Use functions, not macros, for up- and down-casing (Bug#8254).
20494 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
20495 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
20496 to use the following functions instead of these macros.
20497 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
20498 EMACS_INT, since callers assume the returned value fits in int.
20499 (upcase1): Likewise, for UPCASE_TABLE.
20500 (uppercasep, lowercasep, upcase): New static inline functions.
20501 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

20511 (regex_compile, re_match_2_internal): Mark locals as initialized.
20512 (RETALLOC_IF): Define only if needed.
20513 (WORDCHAR_P): Likewise. This one is never needed, but is used
20514 only in a comment talking about a compiler bug, so put inside
20515 the #if 0 of that comment.
20516 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
20517 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

20543 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
20544 New macros, so that the caller can use some names other than
20545 gcpro1, gcpro2, etc.
20546 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
20548 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
20549 argument, for consistency with GCPRO2_VAR, etc: it is now the
20550 prefix of the variable, not the variable itself. All uses
20552 * dired.c (directory_files_internal, file_name_completion):
20553 Rename locals to avoid shadowing.
20555 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
20556 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
20557 dired.c's scmp function, had undefined behavior.
20558 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
20559 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
20560 * buffer.h: ... to here, because these macros use current_buffer,
20561 and the new implementation with inline functions needs to have
20562 current_buffer in scope now, rather than later when the macros
20564 (downcase, upcase1): New static inline functions.
20565 (DOWNCASE, UPCASE1): Reimplement using these functions.
20566 This avoids undefined behavior in expressions like
20567 DOWNCASE (x) == DOWNCASE (y), which previously suffered
20568 from race conditions in accessing the global variables
20569 case_temp1 and case_temp2.
20570 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
20571 * lisp.h (case_temp1, case_temp2): Remove their decls.
20572 * character.h (ASCII_CHAR_P): Move from here ...
20573 * lisp.h: ... to here, so that the inline functions mentioned
20574 above can use them.
20576 * dired.c (directory_files_internal_unwind): Now static.
20578 * fileio.c (file_name_as_directory, directory_file_name):
20579 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
20581 (file_name_as_directory): Use const pointers when appropriate.
20582 (Fexpand_file_name): Likewise. In particular, newdir might
20583 point at constant storage, so make it a const pointer.
20584 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
20585 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
20587 (Fset_file_times, Finsert_file_contents, auto_save_error):

20592 to avoid shadowing.
20594 * marker.c (bytepos_to_charpos): Remove; unused.
20596 * lisp.h (verify_bytepos, count_markers): New decls,
20597 so that gcc does not warn that these functions aren't declared.
20599 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
20600 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
20601 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
20602 (copy_text): Remove unused local var.
20604 * filelock.c (within_one_second): Now static.
20605 (lock_file_1): Rename local to avoid shadowing.
20607 * buffer.c (fix_overlays_before): Mark locals as initialized.
20608 (fix_start_end_in_overlays): Likewise. This function should be
20609 simplified by using pointers-to-pointers, but that's a different
20611 (switch_to_buffer_1): Now static.
20612 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
20613 (report_overlay_modification): Rename locals to avoid shadowing.
20615 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
20616 Fix pointer signedness issue.
20617 (sys_subshell): Mark local as volatile if checking for lint,
20618 to suppress a gcc -Wclobbered warning that does not seem to be right.
20619 (MAXPATHLEN): Define only if needed.
20621 * process.c (serial_open, serial_configure): Move decls from here ...
20622 * systty.h: ... to here, so that they can be checked.
20624 * fns.c (get_random, seed_random): Move extern decls from here ...
20625 * lisp.h: ... to here, so that they can be checked.
20627 * sysdep.c (reset_io): Now static.
20628 (wait_for_termination_signal): Remove; unused.
20630 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

20635 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
20636 (describe_map_tree):
20637 Rename locals to avoid shadowing.
20639 * keyboard.c: Declare functions static if they are not used elsewhere.

20788 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
