1 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
3 * buffer.h (BUF_COMPACT): New macro to follow the common style.
4 * buffer.c (Fget_buffer_create): Use it to set compact field of
5 struct buffer_text to avoid accessing an uninitialized value
6 when compact_buffer is called for the first time.
7 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
9 2012-12-23 Eli Zaretskii <eliz@gnu.org>
11 * w32.c (acl_set_file): If setting the file security descriptor
12 fails, and the new DACL is identical to the existing one, silently
13 return success. This fixes problems for users backing up their
14 own files without having the necessary privileges for setting
17 * w32proc.c (reader_thread): Do not index fd_info[] with negative
19 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
20 after WaitForSingleObject returns normally. This expedites reader
21 thread shutdown when delete_child triggers it.
22 (reap_subprocess): More accurate commentary for why we call
23 delete_child only when cp->fd is negative.
25 * w32.c (sys_close): Do not call delete_child on a subprocess
26 whose handle is not yet closed. Instead, set its file descriptor
27 to a negative value, so that reap_subprocess will call
28 delete_child on that subprocess when its SIGCHLD arrives. This
29 avoids closing handles used for communications between sys_select
30 and reader_thread, which doesn't give sys_select a chance to
31 notice that the process exited and invoke the SIGCHLD handler for
34 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
36 * nsfns.m (Fns_do_applescript): Run event loop until script has
37 been executed (Bug#12969).
38 (ns_run_ascript): Chech as_script for nil, set to nil after
41 2012-12-22 Martin Rudalics <rudalics@gmx.at>
43 * window.c (Fselect_window): Reword doc-string (Bug#13248).

47 * w32term.c (w32fullscreen_hook): New function.
48 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
50 2012-12-21 Eli Zaretskii <eliz@gnu.org>
52 * fileio.c (Finsert_file_contents): Doc fix.
54 * w32proc.c (new_child, delete_child, find_child_pid): For a
55 subprocess, consider its slot being in use as long as its process
56 handle (procinfo.hProcess) is not NULL. This avoids reusing the
57 slot when a new process is started immediately after killing
58 another one, without waiting enough time for the first process to
59 be reaped and resources allocated for it be orderly freed.
61 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
63 2012-12-21 Chong Yidong <cyd@gnu.org>
65 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
67 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
69 2012-12-21 Eli Zaretskii <eliz@gnu.org>
71 * w32.c (get_name_and_id): Always pass NULL as the first argument
72 of lookup_account_sid. Avoids crashes with UNC file names that
73 refer to DFS domains, not to specific machine names. (Bug#12621)
74 Remove now unused argument FNAME; all callers changed.
75 (get_file_owner_and_group): Remove now unused argument FNAME; all
78 2012-12-21 Chong Yidong <cyd@gnu.org>
80 * editfns.c (Finsert_char): Since read-char-by-name now signals an
81 error for invalid chars, don't check for a nil return value.
83 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
85 Avoid calls to CHAR_TO_BYTE if byte position is known.
86 * editfns.c (make_buffer_string_both): Use move_gap_both.
87 (Fbuffer_string): Use make_buffer_string_both.
88 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
90 (buf_bytepos_to_charpos): Likewise.
91 (charpos_to_bytepos): Remove.
92 * fileio.c (Finsert_file_contents): Use move_gap_both.

95 names for byte positions.
96 * lisp.h (charpos_to_bytepos): Remove prototype.
97 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
98 * insdel.c (move_gap): Likewise.

108 proper value of frame-local variables.
110 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
112 * textprop.c (set_text_properties_1): Do not allow NULL interval.
113 Rename 4th argument since it may be buffer or string. Adjust comment.
114 * intervals.c (graft_intervals_info_buffer): Find an interval here.
116 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
118 * coding.c (Fdetect_coding_region): Do not check start and end with
119 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
120 (code_convert_region): Likewise.
122 2012-12-18 Eli Zaretskii <eliz@gnu.org>
124 * w32.c (acl_get_file, acl_set_file): Run the file name through
125 map_w32_filename, and resolve any symlinks in the file name, like
127 (acl_set_file): Call revert_to_self, if any privileges were

137 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
138 propagate redisplay's scrolling (if any) to the right window.
139 (redisplay_internal): Use ensure_selected_frame.
140 (display_mode_lines): Complete last fix.
141 * window.c (select_window_1): New func, extracted from select_window.
142 (select_window): Use it.
143 * window.h (select_window_1): Declare.
145 2012-12-17 Eli Zaretskii <eliz@gnu.org>
147 Emulate Posix ACL APIs on MS-Windows.
148 * w32.c: Include sddl.h and sys/acl.h.

169 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
171 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
172 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
173 for some of that bug's symptoms can now cause Emacs to abort.
174 Remove the workaround.
175 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
176 The bug that caused SIGCHLD to get lost has been fixed, and the
177 workaround for it can now cause Emacs to abort.
179 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
181 * sysdep.c (emacs_abort): Bump backtrace size to 40.
182 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
183 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

187 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
188 (Fcopy_file): Change last arg to `preserve_extended_attributes'
189 and copy ACL entries of file in addition to SELinux context if set.

192 * Makefile.in (LIBACL_LIBS): New macro.
195 2012-12-15 Paul Eggert <eggert@cs.ucla.edu>
197 * fileio.c (internal_delete_file): Use bool for boolean.

204 (register_child): First argument is now pid_t.
205 (record_infile, record_pending_deletion): New prototypes.
207 * w32proc.c (new_child): Initialize input_file and
208 pending_deletion members of the child.
209 (delete_child): Delete the child's temporary input file, if any,
210 that is pending deletion.
211 (register_child): First argument is now pid_t.
212 (record_infile, record_pending_deletion): New functions.
213 (reap_subprocess): Fix a typo in DebPrint string.
214 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
216 * fileio.c (internal_delete_file): Return an int again: non-zero
217 if delete-file succeeds, zero otherwise.
219 * lisp.h (internal_delete_file): Adjust prototype.
221 * callproc.c (Fcall_process): Don't overwrite infile with result
223 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
224 asynchronous subprocess, record the name of the input file name,
226 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
227 delete the file, record it as pending deletion when the subprocess
230 2012-12-14 Eli Zaretskii <eliz@gnu.org>
232 * editfns.c [HAVE_PWD_H]: Include grp.h.
234 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.
236 2012-12-14 Paul Eggert <eggert@cs.ucla.edu>
238 Fix permissions bugs with setgid directories etc. (Bug#13125)
239 * dired.c (Ffile_attributes): Return t as the 9th attribute,
240 to mark it as a placeholder. The old value was often wrong.
241 The only user of this attribute has been changed to use
242 file-ownership-preserved-p instead, with its new group arg.
243 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.

250 2012-12-14 Eli Zaretskii <eliz@gnu.org>
252 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
253 try to get accurate owner and group information from NT file
254 security APIs. This is to make most callers of 'stat' and
255 'lstat', which don't need that information, much faster.
257 * dired.c (Ffile_attributes) [WINDOWSNT]:
258 Set w32_stat_get_owner_group to a non-zero value, to request accurate
259 owner and group information from 'lstat'.
261 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
263 * fileio.c (Finsert_file_contents): Don't put tail into head area,
264 as that confuses set-auto-coding, so insist on the head-read
265 returning the full 1024 bytes. Let lseek compute the tail offset;
266 less work for us. Do not ignore I/O errors when reading the tail.
268 * xdisp.c: Minor style fixes.
269 (init_iterator): Hoist assignment out of if-expression.

287 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
289 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
290 files, fixing a regression from 24.2.
291 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
293 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
295 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
296 fstat shouldn't fail, and if it does fail copy-file should not proceed.
297 Remove unnecessary S_ISLNK test, as (contra the comments) this
298 function can't copy symlinks. Improve quality of error message
299 when attempting to copy files that are neither regular files nor
302 2012-12-12 Dmitry Antipov <dmantipov@yandex.ru>
304 * dispnew.c (set_window_cursor_after_update): Use clip_to_bounds.

310 2012-12-12 Daniel Colascione <dancol@dancol.org>
312 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
313 the dumped Emacs is not a sparse file, greatly improving Cygwin
314 "make bootstrap" performance.
316 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
318 * inotify.c (inotify_callback): Generate an Emacs event for every
319 incoming inotify event.
321 2012-12-11 Eli Zaretskii <eliz@gnu.org>
323 * xdisp.c (handle_face_prop): Fix logic of computing
324 it->start_of_box_run_p.
325 (append_space_for_newline): If the glyph row is R2L, reset the
326 iterator's end_of_box_run_p flag before prepending the space glyph.
327 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
328 iterator's start_of_box_run_p flag before prepending the stretch.
329 (append_glyph, produce_image_glyph, append_composite_glyph)
330 (append_stretch_glyph, append_glyphless_glyph): Reverse the
331 left_box_line_p and right_box_line_p flags of the glyph for R2L
332 glyph rows. (Bug#13011)
334 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
336 * buffer.c (Fset_buffer_multibyte): Do not force redisplay
337 if changed buffer is not shown in a window.
338 * insdel.c (prepare_to_modify_buffer): Likewise.
339 * window.c (replace_buffer_in_windows_safely): Do nothing
340 if buffer is not shown in a window.
341 (Fforce_window_update): Likewise if string or buffer argument
344 2012-12-11 Eli Zaretskii <eliz@gnu.org>
346 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
347 encoded_file_name, which is what it is.

382 (hinst): Remove unneeded extern declaration.
383 (_start): Remove initialization of above variables; remove
384 initialization of hinst, as cache_system_info now does that.
386 * emacs.c (main): Call cache_system_info early in startup; we
387 previously weren't calling it in Cygwin builds.
389 * Makefile.in (ntsource, WINDRES, W32_RES, W#@_RES_LINK):
390 Teach the autoconf build system how to compile a Windows resource file

512 displayed on the left or the right margin, don't consider it as a
513 factor in cursor positioning. (Bug#13108)
515 2012-12-10 Martin Rudalics <rudalics@gmx.at>
517 * editfns.c (Fcompare_buffer_substrings): Reword doc-string.
519 2012-12-10 Paul Eggert <eggert@cs.ucla.edu>
521 * fileio.c (Fsubstitute_in_file_name): Use ptrdiff_t, not int,
524 2012-12-08 Eli Zaretskii <eliz@gnu.org>
526 * w32.c (unsetenv): Return 0 if the input string is too long.
528 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
530 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).
531 * alloc.c (xputenv): New function.
532 * dbusbind.c (Fdbus_init_bus):
534 * xterm.c (x_term_init):
535 Use xputenv instead of setenv or putenv, to detect memory exhaustion.
536 * editfns.c (initial_tz): Move static var decl up.
537 (tzvalbuf_in_environ): New static var.
538 (init_editfns): Initialize these two static vars.
539 (Fencode_time): Don't assume arbitrary limit on EMACS_INT width.
540 Save old TZ value on stack, if it's small.
541 (Fencode_time, set_time_zone_rule): Don't modify 'environ' directly;
542 instead, use xputenv+unsetenv to set and restore TZ.
543 (environbuf): Remove static var. All uses removed.
544 (Fset_time_zone_rule): Do not save TZ and environ;
545 no longer needed here.
546 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
547 Move to inside set_time_zone_rule; they don't need file scope any more.
548 (set_time_zone_rule): Maintain the TZ=value string separately.
549 (syms_of_editfns): Don't initialize initial_tz;
550 init_editfns now does it.
551 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
552 * lisp.h (xputenv): New decl.
554 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
556 * w32fns.c (emacs_abort): Don't do arithmetics on void pointers.
558 2012-12-08 Eli Zaretskii <eliz@gnu.org>
560 * w32.c (unsetenv, sys_putenv): New functions.
562 2012-12-08 Chong Yidong <cyd@gnu.org>
564 * editfns.c (Finsert_char): Make the error message more
565 informative (Bug#12992).
567 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
569 Simplify get_lim_data.
570 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
571 Remove USG and vlimit methods; no longer used these days.
572 Add #error catchall just in case.
574 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
575 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
576 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
577 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
578 (deleted_pid_list, Fdelete_process, create_process)
579 (record_child_status_change, handle_child_signal, deliver_child_signal)
580 (init_process_emacs, syms_of_process):
581 Assume SIGCHLD is defined.
582 (parse_signal): Remove. All uses removed.
583 (abbr_to_signal): New static function.
584 (Fsignal_process): Use it to convert signal names to ints.
585 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
586 kill (getpgrp (), ...).
587 (emacs_sigaction_init): Assume SIGCHLD is defined.
588 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,
589 SIGPIPE, and SIGQUIT are defined. Do not worry about SIGCLD any more.
590 * syssignal.h (EMACS_KILLPG): Remove.
591 All uses replaced by 'kill' with a negative pid.
592 (SIGCHLD): Remove definition, as we now assume SIGCHLD.
593 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
595 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
597 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
598 This will cause a production Emacs to dump core instead of
601 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
603 * frame.c (make_frame): Do not set window's buffer to t.
604 * window.c (Fsplit_window_internal): Likewise. Previously it was
605 used to indicate that the window is being set up. Now we use
606 set_window_buffer for all new windows, so the condition in ...
607 (Fset_window_buffer): ... is always true and can be removed.
609 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
611 Convenient macro to check whether the buffer is hidden.
612 * buffer.h (BUFFER_HIDDEN_P): New macro.
613 * frame.c (make_frame): Use it. Adjust comment.
614 * buffer.c (candidate_buffer): New function.
615 (Fother_buffer, other_buffer_safely): Use it.
617 2012-12-06 Eli Zaretskii <eliz@gnu.org>
619 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
620 if the child process is still running. Instead, exit the wait
621 loop and return zero. (Bug#13086)
623 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
625 * frame.h (x_char_width, x_char_height): Remove prototypes.

634 (command_loop_2, top_level_1): Add static to match prototype.
636 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
638 Fix a recently-introduced delete-process race condition.
639 * callproc.c, process.h (record_kill_process):
640 New function, containing part of the old call_process_kill.
641 (call_process_kill): Use it.
642 This does not change call_process_kill's behavior.
643 * process.c (Fdelete_process): Use record_kill_process to fix a
644 race condition that could cause Emacs to lose track of a child.
646 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
648 Avoid code duplication between prev_frame and next_frame.
649 * frame.c (candidate_frame): New function. Add comment.
650 (prev_frame, next_frame): Use it. Adjust comment.
652 2012-12-06 Eli Zaretskii <eliz@gnu.org>
654 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
655 fails, signal an error instead of continuing with an empty
657 Encode expanded temp file pattern before passing it to mkstemp or
660 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
661 Encode the file name before passing it to dostounix_filename, in
662 case it will downcase it (under w32-downcase-file-names).
665 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
667 Minor call-process cleanups.
668 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
669 at the same time as other platforms, to simplify analysis.
670 No need for fd0_volatile since we have synch_process_fd.
671 Avoid needless emacs_close; arg is always negative.
673 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
675 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
678 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
680 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
681 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
682 and mouse_face_hidden members to a bitfields.
683 * frame.h (struct frame): Remove set-but-not-used space_width member.
684 (FRAME_SPACE_WIDTH): Remove.
685 * nsterm.m, w32term.c, xterm.c: Adjust users.
686 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
687 member. Adjust users. Convert term_initted, delete_in_insert_mode,
688 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
689 members to a bitfields.
691 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
693 Don't let call-process be a zombie factory (Bug#12980).
694 Fixing this bug required some cleanup of the signal-handling code.
695 As a side effect, this change also fixes a longstanding rare race
696 condition whereby Emacs could mistakenly kill unrelated processes,
697 and it fixes a bug where a second C-g does not kill a recalcitrant
698 synchronous process in GNU/Linux and similar platforms.
699 The patch should also fix the last vestiges of Bug#9488,
700 a bug which has mostly been fixed on the trunk by other changes.
701 * callproc.c, process.h (synch_process_alive, synch_process_death)
702 (synch_process_termsig, sync_process_retcode):
703 Remove. All uses removed, to simplify analysis and so that
704 less consing is done inside critical sections.
705 * callproc.c (call_process_exited): Remove. All uses replaced
706 with !synch_process_pid.
707 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
708 These take the role of what used to be in unwind-protect arg.
710 (block_child_signal, unblock_child_signal):
711 New functions, to avoid races that could kill innocent-victim processes.
712 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
713 (call_process_kill): Record killed processes as deleted, so that
714 zombies do not clutter up the system. Do this inside a critical
715 section, to avoid a race that would allow the clutter.
716 (call_process_cleanup): Fix code so that the second C-g works again
717 on common platforms such as GNU/Linux.
718 (Fcall_process): Create the child process in a critical section,
719 to fix a race condition. If creating an asynchronous process,
720 record it as deleted so that zombies do not clutter up the system.
721 Do unwind-protect for WINDOWSNT too, as that's simpler in the
722 light of these changes. Omit unnecessary call to emacs_close
723 before failure, as the unwind-protect code does that.
724 * callproc.c (call_process_cleanup):
725 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
726 * process.c (record_deleted_pid): New function, containing
727 code refactored out of Fdelete_process.
728 (Fdelete_process): Use it.
729 (process_status_retrieved): Remove. All callers changed to use
731 (record_child_status_change): Remove, folding its contents into ...
732 (handle_child_signal): ... this signal handler. Now, this
733 function is purely a handler for SIGCHLD, and is not called after
734 a synchronous waitpid returns; the synchronous code is moved to
735 wait_for_termination. There is no need to worry about reaping
736 more than one child now.
737 * sysdep.c (get_child_status, child_status_changed): New functions.
738 (wait_for_termination): Now takes int * status and bool
739 interruptible arguments, too. Do not record child status change;
740 that's now the caller's responsibility. All callers changed.
741 Reimplement in terms of get_child_status.
742 (wait_for_termination_1, interruptible_wait_for_termination):
743 Remove. All callers changed to use wait_for_termination.
744 * syswait.h: Include <stdbool.h>, for bool.
745 (record_child_status_change, interruptible_wait_for_termination):
747 (record_deleted_pid, child_status_changed): New decls.
748 (wait_for_termination): Adjust to API changes noted above.
750 * bytecode.c, lisp.h (Qbytecode): Remove.
751 No longer needed after 2012-11-20 interactive-p changes.
753 2012-12-03 Eli Zaretskii <eliz@gnu.org>
755 * xdisp.c (redisplay_window): If the cursor is visible, but inside
756 the scroll margin, move point outside the margin. (Bug#13055)
758 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
760 * gtkutil.c (my_log_handler): New function.
761 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
763 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
765 * lisp.h (modify_region): Rename to...
766 (modify_region_1): ...new prototype.
767 * textprop.c (modify_region): Now static. Adjust users.
768 * insdel.c (modify_region): Rename to...
769 (modify_region_1): ...new function to work with current buffer.
770 Adjust comment and users. Use true and false for booleans.
772 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
774 * alloc.c (free_save_value): New function.
775 (safe_alloca_unwind): Use it.
776 * lisp.h (free_save_value): New prototype.
777 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
779 (save_excursion_restore): Adjust to match saved data structure.
780 Use free_save_value to offload some work from GC. Drop obsolete
783 2012-12-03 Chong Yidong <cyd@gnu.org>
785 * fileio.c (Vauto_save_list_file_name): Doc fix.
787 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
789 * w32fns.c: Remove prototype of atof.
790 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
792 (file_dialog_callback): Make it UINT_PTR.
794 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
797 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
798 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
801 2012-12-03 Glenn Morris <rgm@gnu.org>
803 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
805 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
807 Fix xpalloc confusion after memory is exhausted.
808 * alloc.c (xpalloc): Comment fix.
809 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
810 and signals an error, do not clear charset_table_size, as
811 charset_table is still valid.
812 * doprnt.c (evxprintf): Clear *BUF after freeing it.
814 Use execve to avoid need to munge environ (Bug#13054).
815 * callproc.c (Fcall_process):
816 * process.c (create_process):
817 Don't save and restore environ; no longer needed.
818 * callproc.c (child_setup):
819 Use execve, not execvp, to preserve environ.
821 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
823 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
825 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
827 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
828 display for sliced images (Bug#10500).
830 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
832 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
834 * doc.c (Fdocumentation): Re-add handling of function-documentation,
835 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
837 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
839 * xdisp.c (window_outdated): Remove eassert since it hits
840 some suspicious corner cases (see Bug#13007 and Bug#13012).
841 (mode_line_update_needed): New function.
842 (redisplay_internal, redisplay_window): Use it.
843 (ensure_selected_frame): New function.
844 (redisplay_internal, unwind_redisplay): Use it.
845 (redisplay_internal): Move comment about buffer_shared...
846 (buffer_shared_and_changed): ...near to its real use.
848 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
850 * callproc.c (Fcall_process): Don't misreport vfork failure.
852 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
854 * callproc.c (Fcall_process): Fix vfork portability problems.
855 Do not assume that fd[0], count, filefd, and save_environ survive
856 vfork. Fix bug whereby wrong errno value could be reported for
857 pipe failure. Some minor cleanups, too, as follows. Move buf and
858 bufsize to the context where they're needed. Change new_argv to
859 be of type char **, as this is more convenient and avoids casts.
860 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
861 Now local constants, not macros.
863 2012-11-18 Kenichi Handa <handa@gnu.org>
865 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
866 for the variable "f".
868 2012-11-13 Kenichi Handa <handa@gnu.org>
870 * font.c (font_unparse_xlfd): Exclude special characters from the
871 generating XLFD name.
873 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>

883 * fileio.c (Fcopy_file): Assume EISDIR is defined.
884 * gmalloc.c (ENOMEM, EINVAL): Assume they're defined.
885 * gnutls.c (emacs_gnutls_write): Assume EAGAIN is defined.
886 * lread.c (readbyte_from_file): Assume EINTR is defined.
887 * process.c (wait_reading_process_output, send_process) [subprocesses]:
888 Assume EIO and EAGAIN are defined.
889 * unexcoff.c (write_segment): Assume EFAULT is defined.
891 2012-11-27 Eli Zaretskii <eliz@gnu.org>
893 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
896 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
897 highlighting on the frame was cleared. Prevents assertion
898 violations when repeatedly clicking on the "Top" link of the
899 "bread-crumbs" in Info buffers.

911 2012-11-24 Eli Zaretskii <eliz@gnu.org>
913 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
914 between bpos_covered and bpos_max. This fixes cursor display when
915 several display strings follow each other.
917 * .gdbinit (pgx): If the glyph's object is a string, display the
918 pointer to string data, rather than the value of the string object
919 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
921 * indent.c (Fvertical_motion): If the starting position is covered
922 by a display string, return to one position before that, to avoid
923 overshooting it inside move_it_to. (Bug#12930)
925 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
927 * frame.h (struct frame): Remove display_preempted member

934 (struct w32_output): Use bitfields for explicit_parent,
935 asked_for_visible and menubar_active members.
936 Drop unused pending_menu_activation member.
937 * xterm.h (struct x_output): Drop outdated #if 0 code.
938 Use bitfields for explicit_parent, asked_for_visible,
939 has_been_visible and net_wm_state_hidden_seen members.
941 2012-11-23 Eli Zaretskii <eliz@gnu.org>

944 of a literal "/". (Bug#12955)
945 (gl-stamp): Invoke fc.exe directly, not through cmd.
947 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>

950 * dired.c: Assume HAVE_DIRENT_H.
951 (NAMLEN): Remove, replacing with ...
952 (dirent_namelen): New function. All uses changed. Use the GNU macro
953 _D_EXACT_NAMELEN if available, as it's faster than strlen.
954 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
955 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
956 * makefile.w32-in (DIR_H): Remove. All uses replaced with
958 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
959 * ndir.h: Rename to ../nt/inc/dirent.h.
960 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
961 Do not include <dirent.h>; no longer needed.
962 * w32.c: Include <dirent.h> rather than "ndir.h".
964 2012-11-23 Chong Yidong <cyd@gnu.org>
966 * xftfont.c (xftfont_open): Remove duplicate assignment.
968 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
970 * alloc.c (Fgarbage_collect): Unblock input after clearing
971 gc_in_progress to avoid note_mouse_highlight glitch with GC.
972 * frame.h (FRAME_MOUSE_UPDATE): New macro.
973 * msdos.c (IT_frame_up_to_date): Use it here...
974 * w32term.c (w32_frame_up_to_date): ...here...
975 * xterm.c (XTframe_up_to_date): ...and here...
976 * nsterm.m (ns_frame_up_to_date): ...but not here.
977 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
979 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
980 Do not check whether GC is in progress.
982 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
984 * xdisp.c (window_buffer_changed): New function.
985 (update_menu_bar, update_tool_bar): Use it to
986 simplify large 'if' statements.
987 (redisplay_internal): Generalize commonly used
988 'tail' and 'frame' local variables.
990 2012-11-22 Eli Zaretskii <eliz@gnu.org>
992 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
993 with Windows system header.
995 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
997 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
998 * alloc.c: Assume unistd.h exists.
999 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
1000 * sysdep.c (get_current_dir_name): Assume getcwd exists.
1001 (getwd) [USG]: Remove; no longer needed.
1002 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
1003 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
1004 * w32.h (getcwd): Remove decl.
1006 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
1008 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
1009 Make it set selected_window as well.
1010 (update_tool_bar): Use it.
1012 2012-11-21 Ken Brown <kbrown@cornell.edu>
1014 * emacs.c (main): Set the G_SLICE environment variable for all
1015 Cygwin builds, not just GTK builds. See
1016 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
1018 2012-11-21 Eli Zaretskii <eliz@gnu.org>
1020 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1021 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
1022 Define for the MSVC compiler.
1024 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
1026 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
1027 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
1028 dostounix_filename. Prevents crashes down the road, because
1029 dostounix_filename assumes it gets a unibyte string.
1030 Reported by Michel de Ruiter <michel@sentient.nl>, see
1031 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
1033 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>

1037 * lread.c (init_obarray): Set `function' fields to Qnil.
1038 * eval.c (Fcommandp): Ignore Qunbound.
1039 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
1040 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
1041 Test NILP rather than Qunbound.
1042 (Ffmakunbound): Set to Qnil.
1043 (Fsymbol_function): Never signal an error.
1044 (Finteractive_form): Ignore Qunbound.
1046 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
1048 * eval.c (interactive_p): Remove no-longer-used decl.
1050 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
1052 * xdisp.c (buffer_shared): Adjust comment.
1053 (buffer_shared_and_changed): New function.
1054 (prepare_menu_bars, redisplay_internal): Use it to
1055 decide whether all windows or frames should be updated.
1056 (window_outdated): New function.
1057 (text_outside_line_unchanged_p, redisplay_window): Use it.
1058 (redisplay_internal): Likewise. Fix indentation.
1060 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
1062 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
1063 (syms_of_eval): Remove corresponding defsubr.
1064 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
1066 2012-11-19 Daniel Colascione <dancol@dancol.org>
1068 * w32fns.c (Fx_file_dialog):
1069 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
1070 cygwin_convert_file_name*.
1072 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
1073 Rename cygwin_convert_path* to cygwin_convert_file_name*.
1075 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
1077 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
1079 2012-11-18 Eli Zaretskii <eliz@gnu.org>
1081 * w32select.c: Include w32common.h before w32term.h, so that
1082 windows.h gets included before w32term.h uses some of its
1083 features, see below.
1085 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
1087 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
1089 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
1091 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
1093 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
1094 (ns_select): Return at once if events are held (Bug#12834).
1096 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
1098 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
1099 Needed following 2012-10-20 change. (Bug#12902)
1101 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
1103 * w32proc.c (waitpid): Remove unused label get_result.
1105 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
1107 * makefile.w32-in (SYSWAIT_H): New macro.
1108 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
1109 ($(BLD)/sysdep.$(O)): Update dependencies.
1111 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
1113 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
1114 * callproc.c (relocate_fd): Assume F_DUPFD.
1115 * emacs.c, term.c (O_RDWR): Remove.
1116 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
1117 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
1118 * nsterm.m: Assume <fcntl.h> exists.
1119 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
1120 (create_pty, Fmake_network_process, server_accept_connection)
1121 (wait_reading_process_output, init_process_emacs):
1123 (wait_reading_process_output): Put in a special case for WINDOWSNT
1124 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
1125 It's not clear this is needed, but it's a more-conservative change.
1126 (create_process): Assume FD_CLOEXEC.
1127 (create_process, create_pty): Assume O_NOCTTY.
1128 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
1129 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
1130 Omit if not DOS_NT, since F_GETFL is not defined there.
1131 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
1132 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
1134 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
1135 lack it, since gnulib guarantees this.
1136 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
1138 2012-11-17 Eli Zaretskii <eliz@gnu.org>
1140 * w32.c (faccessat): Pretend that directories have the execute bit
1141 set. Emacs expects that, e.g., in files.el:cd-absolute.
1143 * w32proc.c (create_child): Don't clip the PID of the child
1144 process to fit into an Emacs integer, as this is no longer a
1146 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
1147 reaping only the process specified by PID argument, if that is
1148 positive. Use PID instead of dead_child to know which process to
1149 reap. Wait for the child to die only if WNOHANG is not in
1151 (sys_select): Don't set dead_child.
1153 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
1154 as it is no longer needed.
1156 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
1158 (record_child_status_change): Remove the setting of
1159 record_at_most_one_child for the !WNOHANG case.
1161 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
1163 Fix problems in ns port found by static checking.
1164 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
1165 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
1166 not to process group.
1167 (ns_select): Use emacs_write, not write, as that's more robust
1168 in the presence of signals.
1169 (fd_handler:): Check for read errors.
1171 2012-11-16 Glenn Morris <rgm@gnu.org>
1173 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
1175 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
1177 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
1179 2012-11-16 Eli Zaretskii <eliz@gnu.org>
1181 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
1182 use the same value of thread handle.
1183 (start_timer_thread): If the timer thread exited (due to error),
1184 clean up by closing the two handles it used. Duplicate the caller
1185 thread's handle here, so it gets duplicated only once, when
1186 launching the timer thread. Set priority of the timer thread, not
1188 (getitimer): Don't duplicate the caller thread's handle here.
1191 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
1193 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
1196 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
1198 Remove no-longer-used pty_max_bytes variable.
1199 * process.c (pty_max_bytes): Remove; unused.
1200 (send_process): Do not set it.
1202 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
1204 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
1205 Update dependencies.
1207 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
1209 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
1210 This follows up on the 2012-09-29 patch that removed indirection
1211 for the 'function' field. Reported by Sergey Vinokurov in
1212 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
1214 2012-11-14 Eli Zaretskii <eliz@gnu.org>
1216 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
1217 different name, as the MS runtime does not have such a function,
1218 and probably never will.) All callers changed. Ignore DIRFD
1219 value if PATH is an absolute file name, to match Posix spec
1220 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
1223 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
1225 * xdisp.c (echo_area_display, redisplay_internal):
1226 Omit redundant check whether frame_garbaged is set.
1228 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
1230 Use faccessat, not access, when checking file permissions (Bug#12632).
1231 This fixes a bug that has been present in Emacs since its creation.
1232 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
1233 which must set some sort of record. (Torek's bug report was against
1234 a predecessor of GNU Emacs, but GNU Emacs happened to have the
1235 same common flaw.) See Torek's Usenet posting
1236 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
1237 Posted: Fri Apr 8 14:18:56 1983.
1238 * Makefile.in (LIB_EACCESS): New macro.
1240 * callproc.c (init_callproc):
1241 * charset.c (init_charset):
1242 * fileio.c (check_existing, check_executable, check_writable)
1244 * lread.c (openp, load_path_check):
1245 * process.c (allocate_pty):
1247 Use effective UID when checking permissions, not real UID.
1248 * callproc.c (init_callproc):
1249 * charset.c (init_charset):
1250 * lread.c (load_path_check, init_lread):
1251 Test whether directories are accessible, not merely whether they exist.
1252 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
1253 * fileio.c (check_existing, check_executable, check_writable)
1255 Use symbolic names instead of integers for the flags, as they're
1257 (check_writable): New arg AMODE. All uses changed.
1258 Set errno on failure.
1259 (Ffile_readable_p): Use faccessat, not stat + open + close.
1260 (Ffile_writable_p): No need to call check_existing + check_writable.
1261 Just call check_writable and then look at errno. This saves a syscall.
1262 dir should never be nil; replace an unnecessary runtime check
1263 with an eassert. When checking the parent directory of a nonexistent
1264 file, check that the directory is searchable as well as writable, as
1265 we can't create files in unsearchable directories.
1266 (file_directory_p): New function, which uses 'stat' on most platforms
1267 but faccessat with D_OK (for efficiency) if WINDOWSNT.
1268 (Ffile_directory_p, Fset_file_times): Use it.
1269 (file_accessible_directory_p): New function, which uses a single
1270 syscall for efficiency.
1271 (Ffile_accessible_directory_p): Use it.
1272 * xrdb.c (file_p): Use file_directory_p.
1273 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
1274 * lread.c (openp): When opening a file, use fstat rather than
1275 stat, as that avoids a permissions race. When not opening a file,
1276 use file_directory_p rather than stat.
1277 (dir_warning): First arg is now a usage string, not a format.
1278 Use errno. All uses changed.
1279 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
1280 that merely introduced a race.
1281 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
1282 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
1283 and similarly for the other O_* flags.
1284 * w32.c (sys_faccessat): Rename from sys_access and switch to
1285 faccessat's API. All uses changed.
1286 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
1287 (magic_db): Rename from magic_file_p.
1288 (magic_db, search_magic_path): Return an XrmDatabase rather than a
1289 char *, so that we don't have to test for file existence
1290 separately from opening the file for reading. This removes a race
1291 fixes a permission-checking problem, and simplifies the code.
1293 (file_p): Remove; no longer needed.
1295 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
1297 Omit glyphs initialization at startup.
1298 * dispnew.c (glyphs_initialized_initially_p): Remove.
1299 (adjust_frame_glyphs_initially): Likewise. Adjust users.
1300 (Fredraw_frame): Move actual code from here...
1301 (redraw_frame): ...to here. Add eassert. Adjust comment.
1302 (Fredraw_display): Use redraw_frame.
1303 * xdisp.c (clear_garbaged_frames): Likewise.
1305 2012-11-13 Eli Zaretskii <eliz@gnu.org>
1307 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
1308 passed to pint2str and pint2hrstr to be at most the size of the
1309 frame's decode_mode_spec_buffer. This avoids crashes with very
1310 large values of FIELD_WIDTH argument to decode_mode_spec.
1313 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
1315 Fix a race with verify-visited-file-modtime (Bug#12863).
1316 Since at least 1991 Emacs has ignored an mtime difference of no
1317 more than one second, but my guess is that this was to work around
1318 file system bugs that were fixed long ago. Since the race is
1319 causing problems now, let's remove that code.
1320 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
1321 whose time stamp is off by no more than a second. Insist that the
1322 file time stamps match exactly.
1324 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1326 * frame.h (struct frame): Convert external_tool_bar member to
1327 1-bit unsigned bitfield.
1328 * termhooks.h (struct terminal): Remove mouse_moved member since
1329 all users are long dead. Adjust comment on mouse_position_hook.
1331 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1333 Simplify by using FOR_EACH_FRAME here and there.
1334 * frame.c (next_frame, prev_frame, other_visible_frames)
1335 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
1336 * w32term.c (x_window_to_scroll_bar): Likewise.
1337 * window.c (window_list): Likewise.
1338 * xdisp.c (x_consider_frame_title): Likewise.
1339 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
1340 * xfns.c (x_window_to_frame, x_any_window_to_frame)
1341 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
1342 * xmenu.c (menubar_id_to_frame): Likewise.
1343 * xselect.c (frame_for_x_selection): Likewise.
1344 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
1345 (x_window_to_menu_bar): Likewise.
1346 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
1348 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
1350 * data.c (Qdefalias_fset_function): Now static.
1352 Another tweak to vectorlike_header change.
1353 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
1354 Remove, and replace all uses with ...
1355 (next_in_free_list, set_next_in_free_list):
1356 New functions, which respect C's aliasing rules better.
1358 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
1360 * window.c (list4i): Rename from 'quad'. All uses changed.
1361 Needed because <sys/types.h> defines 'quad' on Solaris 10.
1363 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
1365 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
1366 warning about mixing declarations and code in ISO C90.
1368 2012-11-10 Martin Rudalics <rudalics@gmx.at>
1370 * window.c (Fsplit_window_internal): Set combination limit of
1371 new parent window to t iff Vwindow_combination_limit is t;
1372 fixing a regression introduced with the change from 2012-09-22.
1373 (Fset_window_combination_limit): Fix doc-string.
1375 2012-11-10 Eli Zaretskii <eliz@gnu.org>
1377 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
1378 amount when the scroll margins are too large. When scrolling
1379 backwards in the buffer, give up if cannot reach point or the
1380 scroll margin within a reasonable number of screen lines.
1381 Fixes point position in window under scroll-up/down-aggressively when
1382 point is positioned many lines beyond the window top/bottom.
1385 * ralloc.c (relinquish): If real_morecore fails to return memory
1386 to the system, don't crash; instead, leave the last heap
1387 unchanged and return. (Bug#12774)
1389 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1391 * lisp.h (AUTOLOADP): New macro.
1392 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
1393 * data.c (Ffset): Remove special ad-advice-info handling.
1394 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
1396 (Finteractive_form): Simplify.
1397 (Fquo): Don't insist on having at least 2 arguments.
1398 (Qdefalias_fset_function): New var.
1400 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1402 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
1404 * nsfont.m (Qcondensed, Qexpanded): New variables.
1405 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
1406 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
1408 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1410 Fix recently introduced crash on MS-Windows (Bug#12839).
1411 * w32term.h (struct scroll_bar): Use convenient header.
1412 (SCROLL_BAR_VEC_SIZE): Remove.
1413 * w32term.c (x_scroll_bar_create): Use VECSIZE.
1415 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1417 Tweak last vectorlike_header change.
1418 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
1419 vectorlike object on the free list. This is introduced to avoid
1420 some (but not all) pointer casting and aliasing problems, see
1421 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
1422 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
1424 (xvectype, xvecsize): Use them to examine Lisp_Object values.
1426 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1428 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
1429 been removed, so remove them here also.
1431 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1433 * doc.c (Fdocumentation): Handle new property
1434 dynamic-docstring-function to replace the old ad-advice-info.
1436 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
1438 * fns.c (Qeql, hashtest_eq): Now static.
1440 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>

1449 Use same hash function for hashfn_profiler as for hash_string etc.
1450 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
1451 * lisp.h (sxhash_combine): New inline function, with the contents
1452 of the old SXHASH_COMBINE.
1453 * profiler.c (hashfn_profiler): Use it, instead of having a
1454 special hash function containing a comparison that always yields 1.
1456 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1458 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
1459 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
1460 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
1463 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
1465 * image.c (xpm_make_color_table_h): Fix compiler error because
1466 make_hash_table changed.
1468 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
1470 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
1472 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1474 Use ad-hoc comparison function for the profiler's hash-tables.
1475 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
1476 (make_log): Use them.
1477 (handle_profiler_signal): Don't inhibit quit any longer since we don't
1478 call Fequal any more.

1487 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
1488 (hash_lookup, hash_remove_from_table): Move assertion checking of
1489 hashfn result here. Check hash-equality before calling cmpfn.

1501 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
1502 value of w32-scroll-lock-modifier is neither nil nor one of the
1503 known key modifiers. (Bug#12806)
1505 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
1507 Shrink struct vectorlike_header to the only size field.
1508 * lisp.h (enum pvec_type): Avoid explicit enum member values.
1510 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
1511 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
1512 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
1513 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
1514 information from the vector header. Adjust comment.

1529 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
1530 (large_vectors): Change type to struct large_vector.
1531 (allocate_vector_from_block): Simplify.
1532 (PSEUDOVECTOR_NBYTES): Replace with...

1535 (allocate_vectorlike): Likewise.
1536 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
1537 Add easserts. Adjust XSETPVECTYPESIZE usage.
1538 (allocate_buffer): Use BUFFER_PVEC_INIT.
1539 (live_vector_p): Adjust to match large vector.
1540 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
1541 * buffer.h (struct buffer): Add next member.
1542 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
1544 (FOR_EACH_BUFFER): Adjust to match struct buffer change.

1552 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
1554 * keyboard.c (event_to_kboard): Do not dereference
1555 frame_or_window field of SELECTION_REQUEST_EVENT
1556 and SELECTION_CLEAR_EVENT events (Bug#12814).
1557 * xterm.h (struct selection_input_event): Adjust comment.
1559 2012-11-07 Eli Zaretskii <eliz@gnu.org>
1561 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
1562 such as Scroll Lock, if the respective keys are treated as
1563 function keys, not as modifiers. This avoids destroying non-ASCII
1564 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
1566 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
1568 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
1570 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1572 Restore some duplicate definitions (Bug#12814).
1573 This undoes part of the 2012-11-03 changes. Some people build
1574 with plain -g rather than with -g3, and they need the duplicate
1575 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
1576 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
1577 Define as macros, as well as as enums or as constants.
1579 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
1581 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
1582 to keypad keys (Bug#12816).
1584 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1586 Minor adjustments of recently-changed frame functions.
1587 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
1588 known to be a frame (we're in the FRAMEP branch).
1589 * lisp.h (Qframep): Remove decl. frame.h declares this.
1590 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
1591 since they're meant for Lisp fixnum values.
1593 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1595 * window.c (Fwindow_combination_limit): Revert to the only
1596 required argument and adjust docstring as suggested in
1597 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
1598 by Martin Rudalics <rudalics@gmx.at>.
1600 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1602 Widely used frame validity and checking functions.
1603 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
1604 * frame.c (decode_live_frame, decode_any_frame): New functions.
1605 (delete_frame, Fredirect_frame_focus, Fframe_parameters)

1615 * lisp.h (frame_buffer_predicate): Remove prototype.
1616 * buffer.c (Fother_buffer): Use decode_any_frame.
1617 * xdisp.c (Ftool_bar_lines_needed): Likewise.
1618 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
1619 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
1620 (Fclose_font, Ffont_info): Use decode_live_frame.
1621 * fontset.c (check_fontset_name): Likewise.
1622 * terminal.c (Fframe_terminal): Likewise.
1623 * w32fns.c (check_x_frame): Likewise.
1624 * window.c (Fminibuffer_window, Fwindow_at)
1625 (Fcurrent_window_configuration): Likewise.
1626 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
1627 Likewise. Allow zero number of arguments. Adjust docstring.
1628 * dispnew.c (Fredraw_frame): Likewise.
1629 * xfaces.c (frame_or_selected_frame): Remove.
1630 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
1631 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
1632 (Fframe_face_alist): Use decode_live_frame.
1633 * xfns.c (check_x_frame): Likewise.
1635 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1637 * window.c (quad): New function.
1638 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
1639 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
1640 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
1641 (Fwindow_line_height): Use it.
1642 (Fwindow_fringes): Use list3.
1643 (Fwindow_scroll_bars): Use list4.
1644 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
1645 (Fwindow_combination_limit): Allow zero number of arguments.
1647 2012-11-05 Eli Zaretskii <eliz@gnu.org>
1649 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
1651 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
1652 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
1653 file descriptor 2 for standard error. (Bug#12805)
1655 2012-11-05 Chong Yidong <cyd@gnu.org>
1657 * process.c (wait_reading_process_output): Revert previous change.
1659 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
1661 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
1662 This removes code that has been obsolete since around 1990.
1663 * callproc.c (Fcall_process):
1665 * process.c (create_process):
1666 * term.c (dissociate_if_controlling_tty):
1667 Assume setsid exists.
1668 * callproc.c (child_setup): Assume setpgid exists and behaves as
1669 per POSIX.1-1988 or later.
1670 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
1671 * emacs.c (shut_down_emacs):
1672 * sysdep.c (sys_suspend, init_foreground_group):
1673 Assume getpgrp behaves as per POSIX.1-1998 or later.
1674 * msdos.c (setpgrp): Remove.
1675 (tcgetpgrp, setpgid, setsid): New functions.
1676 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
1677 * term.c (no_controlling_tty): Remove; unused.
1678 * w32proc.c (setpgrp): Remove.
1679 (setsid, tcgetpgrp): New functions.
1681 Simplify by assuming __fpending.
1682 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
1683 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
1684 Do not assume that __fpending's result fits in int.
1686 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
1688 Remove EMACS_OUTQSIZE+sleep hack.
1689 * dispnew.c (update_frame_1): Remove hack for terminals slower
1690 than 2400 bps, which throttled Emacs by having it sleep.
1691 This code hasn't worked since at least 2007, when the multi-tty stuff
1692 was added, and anyway those old terminals are long dead.
1693 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
1694 without the dispnew.c change, as dispnew.c doesn't include systty.h.
1696 Fix data-loss with --version (Bug#9574).
1697 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
1698 as we can't assume that emacs_strerror is initialized, and strerror
1699 is good enough here.
1700 (main): Invoke atexit earlier, to catch earlier instances of
1701 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
1703 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
1705 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
1706 (keyDown): Remap keypad keys to X11 virtual key codes.
1708 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
1710 Fix data-loss with --batch (Bug#9574).
1711 * emacs.c: Include <close-stream.h>.
1712 (close_output_streams): New function.
1713 (main): Pass it to atexit, so that Emacs closes stdout and stderr
1714 and handles errors appropriately.
1715 (Fkill_emacs): Don't worry about flushing, as close_output_stream
1718 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
1719 The symptom is a diagnostic "GLib-WARNING **: In call to
1720 g_spawn_sync(), exit status of a child process was requested but
1721 SIGCHLD action was set to SIG_IGN and ECHILD was received by
1722 waitpid(), so exit status can't be returned." The diagnostic
1723 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
1724 The real bug is a race condition between Emacs and glib: Emacs
1725 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
1726 so that glib can't find it. Work around the bug by invoking
1727 waitpid only on subprocesses that Emacs itself creates.
1728 * process.c (create_process, record_child_status_change):
1729 Don't use special value -1 in pid field, as the caller now must
1730 know the pid rather than having the callee infer it.
1731 The inference was sometimes incorrect anyway, due to another race.
1732 (create_process): Set new 'alive' member if child is created.
1733 (process_status_retrieved): New function.
1734 (record_child_status_change): Use it.
1735 Accept negative 1st argument, which means to wait for the
1736 processes that Emacs already knows about. Move special-case code
1737 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
1738 processes that have already been waited for, by testing and
1739 clearing new 'alive' member.
1740 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
1741 now does this internally.
1742 (handle_child_signal): Let record_child_status_change do all
1743 the work, since we do not want to reap all exited child processes,
1744 only the child processes that Emacs itself created.
1745 * process.h (Lisp_Process): New boolean member 'alive'.
1747 Omit duplicate definitions no longer needed with gcc -g3.
1748 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
1749 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
1750 Define only as macros. There's no longer any need to also define
1751 these symbols as enums or as constants, since we now assume
1752 gcc -g3 when debugging.
1754 2012-11-03 Eli Zaretskii <eliz@gnu.org>
1756 * lisp.mk: Adjust comments to the fact that term/internal is now
1757 loaded from loadup.el.
1759 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
1760 (msdos_fatal_signal): New function.
1761 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
1764 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
1765 for GCC versions before 4.
1766 (emacs_raise): Define to call msdos_fatal_signal.
1768 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
1769 iterator when starting in the middle of a display or overlay
1772 2012-11-03 Chong Yidong <cyd@gnu.org>
1774 * process.c (wait_reading_process_output): Clean up the last
1777 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
1779 * process.c (wait_reading_process_output): Avoid a race condition
1780 with SIGIO delivery (Bug#11536).
1782 2012-11-03 Chong Yidong <cyd@gnu.org>
1784 * buffer.c (cursor_type): Untabify docstring.
1786 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1788 * frame.h (struct frame): Drop can_have_scroll_bars member
1789 which is meaningless for a long time. Adjust comments.
1790 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
1791 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
1793 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1795 * window.c (decode_next_window_args): Update window arg after
1796 calling decode_live_window and so fix crash reported at
1797 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
1798 by Juanma Barranquero <lekktu@gmail.com>.
1799 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
1800 * font.c (Ffont_at): Likewise.
1802 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
1804 * widget.c (resize_cb): New function.
1805 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
1806 (EmacsFrameResize): Check if all is up to date before changing frame
1809 2012-11-02 Eli Zaretskii <eliz@gnu.org>
1811 Implement backtrace output for fatal errors on MS-Windows.
1812 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
1813 (BACKTRACE_LIMIT_MAX): New macro.
1814 (w32_backtrace): New function.
1815 (emacs_abort): Use w32_backtrace when the user chooses not to
1816 attach a debugger. Update the text of the abort dialog.
1818 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1820 Window-related stuff cleanup here and there.
1821 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
1822 Use decode_any_window.
1823 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
1824 * xdisp.c (Fformat_mode_line): Likewise.
1825 * font.c (Ffont_at): Use decode_live_window.
1826 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
1827 * window.c (decode_next_window_args): Likewise.
1828 (decode_any_window): Remove static.
1829 * window.h (decode_any_window): Add prototype.
1830 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
1831 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
1834 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1836 Remove pad from struct input_event.
1837 * termhooks.h (struct input_event): Remove padding field.
1839 * keyboard.c (event_to_kboard): Simplify because frame_or_window
1840 member is never cons for a long time. Adjust comment.
1841 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
1842 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
1843 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
1844 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
1846 2012-11-01 Eli Zaretskii <eliz@gnu.org>
1848 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
1850 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
1852 Fix crash when using Emacs as commit editor for git (Bug#12697).
1853 * callproc.c (setpgrp): Remove macro, as we now use setpgid
1854 and it is configured in conf_post.h.
1855 (Fcall_process): Don't invoke both setsid and setpgid; the former
1856 is enough, if it exists.
1857 * callproc.c (Fcall_process, child_setup):
1858 * process.c (create_process): Use setpgid.
1859 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
1861 * dispnew.c (init_display): Initialize the foreground group
1862 if we are running a tty display.
1863 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
1864 * lisp.h (init_foreground_group): New decl.
1865 * sysdep.c (inherited_pgroup): New static var.
1866 (init_foreground_group, tcsetpgrp_without_stopping)
1867 (narrow_foreground_group, widen_foreground_group): New functions.
1868 (init_sys_modes): Narrow foreground group.
1869 (reset_sys_modes): Widen foreground group.

1873 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
1875 2012-10-31 Martin Rudalics <rudalics@gmx.at>
1877 * minibuf.c (read_minibuf): Restore current buffer since
1878 choose_minibuf_frame calling Fset_frame_selected_window may
1879 change it (Bug#12766).

1883 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
1885 2012-10-30 Kenichi Handa <handa@gnu.org>
1887 * font.c (Ffont_at): If WINDOW is specified and it is not
1888 displaying the current buffer, signal an error.
1890 2012-10-29 Daniel Colascione <dancol@dancol.org>
1892 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
1893 In preparation for fixing bug#12739, move these functions from
1896 * coding.h, coding.c: ... to here, and compile them only when
1897 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
1898 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
1900 2012-10-28 Eli Zaretskii <eliz@gnu.org>
1902 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
1903 (timer_loop, getitimer, setitimer): Use it instead of
1904 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
1906 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
1909 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>

1913 (last_appdefined_event): Remove.
1914 (ns_select): Initialize t from last_appdefined_event_data instead
1915 of [last_appdefined_event data1].
1916 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
1917 remove last_appdefined_event (Bug#12698).
1919 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
1921 * frame.c (x_set_font): Catch internal error.
1923 2012-10-27 Eli Zaretskii <eliz@gnu.org>
1925 Avoid overflow in w32 implementation of interval timers.
1926 When possible, for ITIMER_PROF count only times the main thread
1928 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
1929 'volatile ULONGLONG' types. All the other data which was
1930 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
1931 (GetThreadTimes_Proc): New typedef.
1932 (w32_get_timer_time): New function, returns a suitable time value
1934 (timer_loop): Enter critical section when accessing ULONGLONG
1935 values of the itimer_data struct, as these accesses are no longer
1936 atomic. Call 'w32_get_timer_time' instead of 'clock'.
1937 Remove unused variable.
1938 (init_timers): Initialize s_pfn_Get_Thread_Times.
1939 (start_timer_thread): Don't assign itimer->caller_thread here.
1940 (getitimer): Assign itimer->caller_thread here.

1946 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
1947 mouse movement events if the menu bar is active. This avoids
1948 producing a busy "hour-glass" cursor by Windows if the mouse
1949 pointer is positioned over a tooltip shown for some menu item.
1951 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
1953 Don't assume process IDs fit in int.
1954 * emacs.c (shut_down_emacs) [!DOS_NT]:
1955 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
1956 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
1957 Use pid_t, not int, to store process IDs, as 'int'
1958 is not wide enough on a few platforms (e.g., AIX and IRIX).
1960 2012-10-23 Kenichi Handa <handa@gnu.org>
1962 The following change is to make face-font-rescale-alist work
1963 correctly for non-ASCII fonts.
1965 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
1966 (font_open_for_lface): Handle Vface_font_rescale_alist.

1981 2012-10-21 Glenn Morris <rgm@gnu.org>
1983 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
1985 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>

1988 * frame.c (Fmouse_position, Fmouse_pixel_position):
1989 * xdisp.c (produce_stretch_glyph):
1990 Declare local vars only when they're needed.
1991 This is clearer and avoids a warning on OpenBSD about unused vars.

1993 This is safer, and avoids OpenBSD warnings about unused vars.
1994 * keyboard.c (record_menu_key): Remove unnecessary decl.
1995 (poll_timer): Define only if POLL_FOR_INPUT is defined.
1996 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
1997 as our definition clashes with OpenBSD's.
1998 * xfaces.c (load_face_colors, check_lface_attrs)
1999 (get_lface_attributes_no_remap, get_lface_attributes)
2000 (lface_fully_specified_p, x_supports_face_attributes_p)
2001 (tty_supports_face_attributes_p, face_fontset, realize_face)
2002 (realize_x_face, realize_tty_face):
2003 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
2004 merely Lisp_Object *. This is more informative and avoids
2005 a warning on OpenBSD about accessing beyond an object's size.
2007 2012-10-20 Chong Yidong <cyd@gnu.org>
2009 * lread.c (Fload): Doc fix (Bug#12592).

2035 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
2036 (staticpro): If we run out of staticpro slots, die with an
2037 informative error instead of just calling emacs_abort.
2039 2012-10-18 Martin Rudalics <rudalics@gmx.at>
2041 Fix two flaws reported by Dmitry Antipov.

2299 the same pointer-to-int (now pointer-to-boolean) &input_pending,

2301 input_pending. All callers changed.
2302 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
2303 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's

2354 * xdisp.c (start_hourglass): Call w32_note_current_window when
2355 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
2356 build that caused Emacs to display the hourglass cursor forever.
2358 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
2359 which is broken under remote desktop, calculate the number of
2360 colors available for a display based on the display's number of
2361 planes and number of bits per pixel per plane. (bug#10397).
2363 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
2365 * nsfont.m (Vfonts_in_cache): New variable.
2366 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
2367 are used. Add cached fonts to Vfonts_in_cache.
2368 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
2370 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
2372 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
2374 (FONT_H): Define after FRAME_H.
2375 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
2376 Update dependencies.
2378 * w32term.c: Remove leftover declaration of keyboard_codepage.
2380 2012-10-08 Eli Zaretskii <eliz@gnu.org>
2382 * makefile.w32-in (FONT_H): Add $(FRAME_H).
2383 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
2384 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
2385 (GLOBAL_SOURCES): Add cygw32.c.
2386 ($(BLD)/unexw32.$(O)):
2388 ($(BLD)/w32console.$(O)):
2389 ($(BLD)/w32fns.$(O)):
2390 ($(BLD)/w32heap.$(O)):
2391 ($(BLD)/w32menu.$(O)):
2392 ($(BLD)/w32proc.$(O)): Add w32common.h.
2394 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
2396 (x_to_w32_color): Don't modify the argument, modify a copy instead.
2398 2012-10-08 Daniel Colascione <dancol@dancol.org>
2400 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
2401 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
2402 accidental message numbering hole. Change other messages to
2405 * w32select.h (HAVE_W32SELECT): Remove.
2407 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
2408 w32common.h instead of w32heap.h.
2410 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
2411 (get_allocation_unit, get_processor_type, get_w32_major_version)
2412 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
2413 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
2414 (OS_NT, os_subtype, cache_system_info): Move declarations to
2417 * w32heap.c: Include w32common.h.
2418 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
2419 (w32_minor_version, w32_build_number, w32_subtype):
2420 Remove duplicate definitions.
2422 * w32fns.c: Include w32common.h; include w32heap.h only in
2425 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
2426 Use `report_file_error' instead of `error' in order to better
2427 inform users of what went wrong. Increase NTGUI_UNICODE file
2428 dialog box file name length to 32k, the maximum allowed by the NT
2431 * w32common.h: New file.
2432 (ROUND_UP, ROUND_DOWN, get_page_size)
2433 (get_allocation_unit, get_processor_type, get_w32_major_version)
2434 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
2435 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
2436 (OS_NT, os_subtype, cache_system_info): Move here.
2438 * unexw32.c, unexcw.c: Include w32common.h.
2440 * emacs.c (main): Use (defined (WINDOWSNT) || defined
2441 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
2442 to call syms_of_w32select.
2444 * cygw32.h: Remove obsolete EXFUN declarations.
2446 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
2448 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
2449 of w32inevt.o from SOME_MACHINE_OBJECTS.
2451 2012-10-08 Daniel Colascione <dancol@dancol.org>
2453 * image.c: Permanent fix for JPEG compilation issue --- limit
2454 jpeglib `boolean' redefinition to Cygwin builds.
2456 2012-10-08 Eli Zaretskii <eliz@gnu.org>
2458 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
2460 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
2463 2012-10-08 Daniel Colascione <dancol@dancol.org>
2465 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
2466 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
2467 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
2468 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
2469 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
2470 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
2471 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
2472 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
2473 now a supported configuration.
2475 * Makefile.in: consolidate image variables into LIBIMAGE; add
2476 W32_OBJ and W32_LIBS. Compile new files.
2479 (_DebPrint) declare tracing facility for W32 debugging. We need
2480 to unify tracing later.
2482 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
2483 unconditional use of W32 Unicode functions. Cygwin runs only on
2484 100% Unicode operating systems.
2486 * cygw32.c: New file. Define Cygwin-specific facilities.
2487 (Fcygwin_convert_path_to_windows)
2488 (Fcygwin_convert_path_from_windows): New user functions for
2489 accessing Cygwin path-munging routines.
2491 * cygw32.h: New file.
2492 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
2493 UTF-16LE strings temporarily inside non-Lisp-visible string
2496 (w32_strerror): Just what it says on the tin.
2498 * emacs.c: Make the NS fork-then-exec code for daemon-launching
2499 also run for Cygwin; both systems have the same problem with using
2500 GUI facilities in a forked child. Also call syms_of_cygw32,
2501 syms_of_w32select in correct places.
2503 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
2504 needs fork-then-exec for daemon launching.
2506 * font.h: Include frame.h.
2508 * image.c: Use the image library cache machinery only when we're
2509 compiling for native WINDOWSNT; Cygwin can use shared libraries
2510 like any other Unixlike system.
2512 * keyboard.c: Clarify a comment regarding the input loop.
2514 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
2515 functions directly instead of trying to detect at runtime that our
2516 host operating system supports them. We make this change for two
2517 reasons: Cygwin lacks support for the multibyte character
2518 conversion functions used by the legacy menu code, and Cygwin
2519 never needs to rely on non-Unicode APIs.
2521 * unexw32.c (hinst): Declare extern.
2523 * w32.c: Change header order;
2524 (w32_strerror): Move to w32fns.c because we need it for
2525 non-WINDOWSNT builds.
2527 * w32.h: Add #error macro to make sure we don't include w32.h for
2528 Cygwin builds. Remove w32select declarations.
2530 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
2531 w32fns.c. w32console.c is WINDOWSNT-only.
2533 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
2534 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
2536 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
2537 (w32_major_version, w32_minor_version, w32_build_number)
2538 (os_subtype, sound_type): Define here
2539 (w32_defined_color): Make color parameter const for consistency
2540 with other _defined_color functions.
2541 (w32_createwindow): Unconditionally call w32_init_class instead of
2542 doing so only when hprevinst is non-NULL. Plumbing hprevinst
2543 through the code is complex and unnecessary because class
2544 registration is practically free.
2545 (w32_name_of_message): New EMACSDEBUG-only function.
2546 (Fset_message_beep): Move here
2547 (Fx_open_connection): Require that the display name for Windows be
2548 "w32" for consistency, emacsclient disambiguation, and maybe, one
2549 day, multi-window-system support.
2550 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
2551 Cygwin files for W32 GUI facilities, since these clearly don't
2552 expect Cygwin names.
2553 (_DebPrint): Define.
2554 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
2555 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
2556 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
2557 (w32_last_error): Remove.
2559 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
2561 * w32heap.c (syspage_mask): Declare here.
2562 (cache_system_info): Remove.
2564 * w32inevt.c (faked_key): Define globally, not statically.
2565 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
2566 (w32_console_toggle_lock_key): Move to w32fns.c.
2568 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
2570 * w32proc.c (_DebPrint): Move to w32fns.c.
2571 * w32select.c: Include string.h, stdio.h for Cygwin.
2572 * w32select.h: New File.
2574 * w32term.c: Include io.h for non-CYGWIN builds; needed for
2576 (w32_message_fd): New variable. Under Cygwin, holds the file
2577 descriptor the system used to tell us about pending thread
2580 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
2581 that prevented compilation under non-WINDOWSNT systems.
2583 (w32_initialize): Open /dev/windows and assign it to
2584 w32_message_fd. Provide w32 feature.
2586 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
2587 (WM_EMACS_INPUT_READY): add.
2588 (prepend_msg, w32_message_fd): Declare globally.
2591 (keyboard_handle): Use only when WINDOWSNT.
2592 (notify_msg_ready): New function. Posts a message to the main
2593 thread's message queue under CYGWIN, which wakes up the main
2594 thread from select(2) by making the /dev/windows file descriptor
2595 ready. Under WINDOWSNT, it sets an event the same way the old
2598 (post, prepend_msg): Actually call notify_msg_ready instead of
2599 setting the input event directly.
2601 2012-10-07 Eli Zaretskii <eliz@gnu.org>
2603 * ralloc.c (relinquish): If a heap is ready to be relinquished,
2604 but it still has blocs in it, don't return it to the system,
2605 instead of aborting. (Bug#12402)
2607 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
2609 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
2611 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
2612 MAC_OS_X_VERSION_10_6.
2613 (syms_of_nsterm): Remove comment about Panther and above for
2615 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
2616 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
2617 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
2619 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
2620 MAC_OS_X_VERSION_10_4.
2622 * nsmenu.m (fillWithWidgetValue:): Remove code for <
2623 MAC_OS_X_VERSION_10_2.
2625 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
2627 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
2628 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
2630 * nsterm.m (ns_in_resize): Remove (Bug#12479).
2631 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
2632 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
2633 Remove ns_in_resize check.
2634 (ns_clear_frame_area): Remove resize handle code.
2636 * nsfns.m (ns_in_resize): Remove.
2637 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
2638 Remove ns_in_resize check.
2640 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
2642 Improve sys_siglist detection.
2643 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
2644 defined as a macro, as is done in Solaris.
2645 (sys_siglist_entries): New macro.
2646 (save_strsignal): Use it.
2647 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
2648 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
2650 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
2652 * nsfns.m (Fx_create_frame): Call x_default_parameter with
2653 fullscreen/Fullscreen.
2655 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
2656 tobar_height is new.
2658 * nsterm.m (x_make_frame_visible): Check for fullscreen.
2659 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
2660 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
2661 (windowDidResize:): Check for correct window if old style fullscreen.
2662 Capitalize word in comment. Remove incorrect comment.
2663 (initFrameFromEmacs:): tbar_height renamed tibar_height.
2664 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
2665 error in drawing background.
2666 (toggleFullScreen:): Remove comment. Rearrange calls.
2667 Set toolbar values to zero, save old height in tobar_height.
2668 Restore tool bar height when leaving fullscreen.
2669 (canBecomeMainWindow): New function.
2671 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
2673 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
2675 2012-10-05 Eli Zaretskii <eliz@gnu.org>
2677 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
2679 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
2680 that time stamps of directories could also be changed.
2681 Don't request the too broad GENERIC_WRITE, only the more restrictive
2682 FILE_WRITE_ATTRIBUTES access rights.
2684 * fileio.c (Fset_file_times): Special-case ignoring errors for
2685 directories only on MSDOS, not on MS-Windows.
2687 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
2689 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
2691 2012-10-04 Eli Zaretskii <eliz@gnu.org>
2693 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
2694 see whether CreateFile failed.
2696 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
2698 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
2699 to avoid similar races.
2700 * keyboard.c (pending_signals): Now bool, not int.
2702 Port timers to OpenBSD, plus check for timer failures.
2703 OpenBSD problem reported by Han Boetes.
2704 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
2706 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
2707 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
2708 like OpenBSD, which has timer_settime but does not declare it.
2709 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
2710 whether to use itimerspec-related primitives. All uses of
2711 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
2713 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2715 * profiler.c (handle_profiler_signal): Fix a malloc race
2716 that caused Emacs to hang on Fedora 17 when profiling Lisp.
2718 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
2720 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
2722 2012-10-02 Eli Zaretskii <eliz@gnu.org>
2724 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
2725 consistent with the change in return value of 'safe_strsignal'.
2727 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2729 Prefer plain 'static' to 'static inline' (Bug#12541).
2730 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
2731 (bidi_set_sor_type, bidi_push_embedding_level)
2732 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
2733 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
2734 (bidi_cache_search, bidi_cache_ensure_space)
2735 (bidi_cache_iterator_state, bidi_cache_find)
2736 (bidi_peek_at_next_level, bidi_set_paragraph_end)
2737 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
2738 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
2739 Now 'static', not 'static inline'.
2741 Count overruns when profiling; change units to ns.
2742 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
2743 Give extra weight to samples after overruns, to attempt to count
2744 the time more accurately.
2745 (setup_cpu_timer): Change sampling interval units from ms to ns, since
2746 the underlying primitives nominally do ns.
2747 (Fprofiler_cpu_start): Document the change. Mention that
2748 the sampling intervals are only approximate.
2750 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
2752 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
2754 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
2755 case for the special 0 coding-system.
2757 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
2758 (Fmake_overlay): Remove redundant tests.
2759 (fix_start_end_in_overlays): Remove redundant recentering.
2761 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
2763 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
2764 Update dependencies.
2766 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2768 Fix a malloc race condition involving strsignal.
2769 A signal can arrive in the middle of a malloc, and Emacs's signal
2770 handler can invoke strsignal, which can invoke malloc, which is
2771 not portable. This race condition bug makes Emacs hang on GNU/Linux.
2772 Fix it by altering the signal handler so that it does not invoke
2774 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
2775 * process.c (status_message): Use const pointer, in case strsignal
2776 is #defined to safe_strsignal.
2777 * sysdep.c (sys_siglist, init_signals): Always define and
2778 initialize a substitute sys_siglist if the system does not define
2779 one, even if HAVE_STRSIGNAL.
2780 (safe_strsignal): Rename from strsignal. Always define,
2781 using sys_siglist. Return a const pointer.
2782 * syssignal.h (safe_strsignal): New decl.
2783 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
2785 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2787 * w32proc.c (timer_loop): Fix code that waits for timer
2788 expiration, to avoid high CPU usage.
2790 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
2792 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
2793 (sweep_weak_table): Remove redundant prototypes.
2795 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
2797 * emacs.c: Move the inclusion of TERM_HEADER after including
2798 windows.h on WINDOWSNT. This avoids compilation problems with
2801 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2803 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
2804 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
2805 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
2806 as the previous version used 'void *'.
2808 * ralloc.c (ROUNDUP): Fix last change.
2809 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
2812 * w32proc.c <disable_itimers>: New static flag.
2813 (init_timers): Initialize it to zero, after creating the critical
2814 sections used by the timer threads.
2815 (term_timers): Set to 1 before deleting the critical sections.
2816 (getitimer, setitimer): If disable_itimers is non-zero, return an
2817 error indication without doing anything. Reported by Fabrice
2818 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
2819 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
2821 [!HAVE_SETITIMER]: Behave as the previous version that didn't
2824 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
2825 term_ntproc after all the other bookkeeping, to get timers working
2826 as long as possible.

2830 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
2831 Suggested by Juri Linkov in
2832 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
2834 Prefer plain 'static' to 'static inline' (Bug#12541).
2835 With static functions, modern compilers inline pretty well by
2836 themselves; advice from programmers often hurts as much as it helps.
2837 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
2838 this change shrinks the text size of the Emacs executable by 1.1%
2839 without affecting CPU significantly in my benchmark.
2840 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)
2841 (live_float_p, live_misc_p, live_vector_p, live_buffer_p)

2916 Now 'static', not 'static inline'.
2919 (bidi_copy_it): Do the whole copy with a single memcpy.
2920 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
2922 Revert the FOLLOW-SYMLINKS change for file-attributes.
2923 Doing it right would require several changes to Tramp, and there's
2924 not enough time to get that tested before the freeze today.
2925 * dired.c (directory_files_internal, Ffile_attributes):
2928 * frame.c (x_report_frame_params): Port better to wider ints.
2929 Do not assume that EMACS_UINT is the same width as uprintmax_t,

3133 (handle_profiler_signal): Rename from sigprof_handler_1,
3134 for consistency with other handlers. Do not check whether
3135 cpu_log is a hash-table if garbage collecting, since it

3138 for consistency with other handlers.
3139 (setup_cpu_timer): New function, with much of what used to be in

3141 Prefer timer_settime if available, and prefer
3142 thread cputime clocks, then process cputime clocks, then
3143 monotonic clocks, to the old realtime clock. Use make_timeval
3144 to round more-correctly when falling back to setitimer.
3145 (Fprofiler_cpu_start): Use it.
3146 (Fprofiler_cpu_stop): Prefer timer_settime if available.
3147 Don't assume that passing NULL as the 2nd argument of setitimer
3148 is the same as passing a pointer to all-zero storage.

3150 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
3151 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
3152 non-fatal signal handlers. Ignore SIGPROF on startup.
3153 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
3154 in profiler.c, since sysdep.c now uses it.
3156 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

3212 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
3213 Since this stuff is now private to charset.c, there's no need for
3214 a public macro and no need to inline by hand.

3262 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
3264 Move Vlibrary_cache to emacs.c and reset before dumping.
3266 * lisp.h (reset_image_types): Declare.
3267 [WINDOWSNT] (Vlibrary_cache): Declare.
3269 * image.c (reset_image_types): New function.
3271 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.
3272 (syms_of_emacs) [WINDOWSNT] <Vlibrary_cache>: Initialize and staticpro.
3273 (Fdump_emacs): Reset Vlibrary_cache and image_types.
3275 * w32.c (Vlibrary_cache): Do not define; moved to emacs.c
3276 (globals_of_w32) <Vlibrary_cache>: Do not initialize.
3278 * w32.h (Vlibrary_cache): Do not declare.
3280 2012-09-25 Eli Zaretskii <eliz@gnu.org>
3282 * w32proc.c (sys_signal): Handle all signals defined by the
3283 MS-Windows runtime, not just SIGCHLD. Actually install the signal
3284 handlers for signals supported by Windows. Don't override
3285 term_ntproc as the handler for SIGABRT.
3286 (sigaction): Rewrite to call sys_signal instead of duplicating its
3288 (sys_kill): Improve commentary.
3290 * w32.c (term_ntproc): Accept (and ignore) one argument, for
3291 consistency with a signature of a signal handler. All callers
3293 (init_ntproc): Accept an argument DUMPING. If dumping, don't
3294 install term_ntproc as a signal handler for SIGABRT, as that
3295 should be done by the dumped Emacs.
3297 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
3299 * w32select.c (term_w32select): Protect against repeated
3300 invocation by setting clipboard_owner to NULL after calling
3303 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
3304 and term_ntproc to their modified signatures.
3306 * character.c (char_string, string_char): Remove calls to
3307 MAYBE_UNIFY_CHAR. See the discussion starting at
3308 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
3311 2012-09-25 Chong Yidong <cyd@gnu.org>
3313 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
3315 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
3317 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
3318 when encountering an unknown bytecode.
3320 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
3322 image.c, indent.c: Use bool for booleans.
3323 * dispextern.h (struct image_type): Members valid_p, load, init
3324 now return bool, not int. All uses changed.
3325 * image.c: Omit unnecessary static decls.
3326 (x_create_bitmap_mask, x_build_heuristic_mask):
3327 Return void, not int, since callers don't care about the return value.

3356 Use bool for booleans.
3358 2012-09-24 Chong Yidong <cyd@gnu.org>
3360 * chartab.c (Fset_char_table_default): Obsolete function removed.
3362 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3364 Move pid_t related decls out of lisp.h.
3365 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
3366 (interruptible_wait_for_termination):
3367 Move these decls from lisp.h to syswait.h, since they use pid_t.
3368 Needed on FreeBSD; see Herbert J. Skuhra in
3369 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
3370 * callproc.c: Include syswait.h.

3388 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
3389 * xfns.c (Fx_show_tip) [USE_GTK]:
3390 Use bool for boolean.
3391 * gtkutil.c (xg_update_frame_menubar):
3392 * xmenu.c (update_frame_menubar):
3393 Return void, not int, since caller ignores return value.
3394 * gtkutil.c (xg_change_toolbar_position):
3397 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
3399 * makefile.w32-in (BLOCKINPUT_H): Remove.

3416 2012-09-23 Eli Zaretskii <eliz@gnu.org>
3418 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
3419 fatal_error_backtrace.
3421 * w32proc.c (sys_kill): Undo last change: don't do anything when
3422 invoked to deliver SIGABRT to our own process. This is now
3423 handled by emacs_raise.
3425 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
3427 * w32term.c (w32_read_socket): Remove leftover reference to
3428 interrupt_input_pending.
3430 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3432 Do not use SA_NODEFER.
3433 Problem reported by Dani Moncayo in
3434 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
3436 * sysdep.c (emacs_abort): Do not reset signal handler.
3437 * emacs.c (terminate_due_to_signal): Reset signal handler here.
3438 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
3439 wanted even on POSIXish hosts, and it doesn't work on Windows.
3441 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3443 * xterm.c (x_term_init): Call fixup_locale before and after calling
3444 gtk_init (Bug#12392).
3446 2012-09-23 Chong Yidong <cyd@gnu.org>
3448 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
3449 Vdynamic_library_alist.
3451 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
3452 (Fgnutls_available_p): Caller changed.
3454 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
3455 (Flibxml_parse_xml_region): Likewise.
3457 * dispextern.h (struct image_type): Remove arg from init function.
3459 * image.c (Finit_image_library, lookup_image_type)
3460 (define_image_type): Remove now-unneeded second arg.
3461 (init_xpm_functions, init_png_functions, init_jpeg_functions)
3462 (init_tiff_functions, init_gif_functions, init_svg_functions):
3463 Arglist and w32_delayed_load calling convention changed.
3464 (gs_type): Remove init_gs_functions; there is no such function.
3465 (valid_image_p, make_image): Fix caller to lookup_image_type.
3467 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3469 Simplify and avoid signal-handling races (Bug#12471).
3471 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
3472 Avoid recursive loop if there's a fatal error in the function itself.
3473 * atimer.c (pending_atimers):
3474 * blockinput.h: Don't include "atimer.h"; no longer needed.
3475 (interrupt_input_pending): Remove. All uses removed.
3476 pending_signals now counts both atimers and ordinary interrupts.
3477 This is less racy than having three separate pending-signal flags.
3478 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
3480 Rename from their upper-case counterparts BLOCK_INPUT,
3481 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
3482 INPUT_BLOCKED_P, and turn into functions. All uses changed.
3483 This makes it easier to access volatile variables more accurately.
3484 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
3485 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
3486 that's more reliable if the code is buggy and sets
3487 interrupt_input_blocked to a negative value. All uses changed.
3488 * atimer.c (deliver_alarm_signal):
3489 Remove. No need to deliver this to the parent; any thread can
3490 handle this signal now. All uses replaced by underlying handler.
3491 * atimer.c (turn_on_atimers):
3492 * dispnew.c (handle_window_change_signal):
3493 * emacs.c (handle_danger_signal):
3494 * keyboard.c (kbd_buffer_get_event):
3495 Don't reestablish signal handler; not needed with sigaction.
3496 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
3498 Rework to avoid unnecessary accesses to volatile variables.
3499 (UNBLOCK_INPUT_TO): Now a function.
3500 (totally_unblock_input, unblock_input): New decls.
3501 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
3502 (init_data): Remove. Necessary stuff now done in init_signal.
3503 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
3504 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
3505 (fatal_error_code): Remove; no longer needed.
3506 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
3507 it doesn't always backtrace. All uses changed. No need to reset
3508 signal to default, since sigaction and/or die does that for us now.
3509 Use emacs_raise (FOO), not kill (getpid (), FOO).
3510 (main): Check more-accurately whether we're dumping.
3511 Move fatal-error setup to sysdep.c
3512 * floatfns.c: Do not include "syssignal.h"; no longer needed.
3513 * gtkutil.c (xg_get_file_name, xg_get_font):
3514 Remove no-longer-needed signal-mask manipulation.
3515 * keyboard.c, process.c (POLL_FOR_INPUT):
3516 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
3517 * keyboard.c (read_avail_input): Remove.
3518 All uses replaced by gobble_input.
3519 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
3520 (kbd_buffer_store_event_hold, gobble_input):
3521 (record_asynch_buffer_change) [USABLE_SIGIO]:
3522 (store_user_signal_events):
3523 No need to mess with signal mask.
3524 (gobble_input): If blocking input and there are terminals, simply
3525 set pending_signals to 1 and return. All hooks changed to not
3526 worry about whether input is blocked.
3527 (process_pending_signals): Clear pending_signals before processing
3528 them, in case a signal comes in while we're processing.
3529 By convention callers now test pending_signals before calling us.
3530 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
3531 New functions, to support changes to blockinput.h.
3532 (handle_input_available_signal): Now extern.
3533 (reinvoke_input_signal): Remove. All uses replaced by
3535 (quit_count): Now volatile, since a signal handler uses it.
3536 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
3537 All callers changed. Block SIGINT only if not already blocked.
3538 Clear sigmask reliably, even if Fsignal returns, which it can.
3539 Omit unnecessary accesses to volatile var.
3540 (quit_throw_to_read_char): No need to restore sigmask.
3541 * keyboard.c (gobble_input, handle_user_signal):
3542 * process.c (wait_reading_process_output):
3543 Call signal-handling code rather than killing ourselves.
3544 * lisp.h: Include <float.h>, for...
3545 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
3546 (pending_signals): Now volatile.
3547 (syms_of_data): Now const if IEEE floating point.
3548 (handle_input_available_signal) [USABLE_SIGIO]:
3549 (terminate_due_to_signal, record_child_status_change): New decls.
3550 * process.c (create_process): Avoid disaster if memory is exhausted
3551 while we're processing a vfork, by tightening the critical section
3553 (send_process_frame, process_sent_to, handle_pipe_signal)
3554 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
3556 (send_process): No need for setjmp/longjmp any more, since the
3557 SIGPIPE stuff is now gone. Instead, report an error if errno
3559 (record_child_status_change): Now extern. PID and W are now args.
3560 Return void, not bool. All callers changed.
3561 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
3562 Remove. All uses removed. This bug should be fixed now in a
3564 (wait_for_termination_1): Use waitpid rather than sigsuspend,
3565 and record the child status change directly. This avoids the
3566 need to futz with the signal mask.
3567 (process_fatal_action): Move here from emacs.c.
3568 (emacs_sigaction_flags): New function, containing
3569 much of what used to be in emacs_sigaction_init.
3570 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
3571 caught by emacs, to make races less likely.
3572 (deliver_process_signal): Rename from handle_on_main_thread.
3574 (BACKTRACE_LIMIT_MAX): Now at top level.
3575 (thread_backtrace_buffer, threadback_backtrace_pointers):
3577 (deliver_thread_signal, deliver_fatal_thread_signal):
3578 New functions, for more-accurate delivery of thread-specific signals.
3579 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
3580 (deliver_arith_signal): Handle in this thread, not
3581 in the main thread, since it's triggered by this thread.
3582 (maybe_fatal_sig): New function.
3583 (init_signals): New arg DUMPING so that we can be more accurate
3584 about whether we're dumping. Caller changed.
3585 Treat thread-specific signals differently from process-general signals.
3586 Block all signals while handling fatal error; that's safer.
3587 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
3589 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
3590 Ignore SIGPIPE unless batch.
3591 (emacs_backtrace): Output backtrace for the appropriate thread,
3592 which is not necessarily the main thread.
3593 * syssignal.h: Include <stdbool.h>.
3594 (emacs_raise): New macro.
3595 * xterm.c (x_connection_signal): Remove; no longer needed
3596 now that we use sigaction.
3597 (x_connection_closed): No need to mess with sigmask now.
3598 (x_initialize): No need to reset SIGPIPE handler here, since
3599 init_signals does this for us now.
3601 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3603 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
3604 background rect may be larger (Bug#12245).
3606 2012-09-23 Chong Yidong <cyd@gnu.org>
3608 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
3610 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3612 * .gdbinit: Just stop at fatal_error_backtrace.
3613 See Stefan Monnier's request in
3614 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
3615 Remove no-longer-used query of system type.
3617 2012-09-22 Chong Yidong <cyd@gnu.org>
3619 * search.c (Freplace_match): Doc fix (Bug#12325).
3621 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
3623 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
3624 (Fline_end_position): Doc fix.
3626 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
3628 2012-09-22 Chong Yidong <cyd@gnu.org>
3630 * dispextern.h (struct image_type): Add new slot, storing a type
3631 initialization function.
3633 * image.c (define_image_type): Call the image initializer function
3634 if it is defined. Arguments and return value changed.
3635 (valid_image_p, make_image): Callers changed.
3636 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
3637 (gif_type, imagemagick_type, svg_type, gs_type):
3638 Add initialization functions.
3639 (Finit_image_library): Call lookup_image_type.
3640 (CHECK_LIB_AVAILABLE): Macro deleted.
3641 (lookup_image_type): Call define_image_type here, rather than via
3642 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
3643 (syms_of_image): Move define_image_type calls for xbm_type and
3644 pbm_type to lookup_image_type.
3646 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3648 * keyboard.c (timer_check_2): Move calculation of 'timers' and
3649 'idle_timers' from here ...
3650 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
3651 lists, to avoid infloops when the timer does something stupid,
3652 like reinvoke itself with the same or smaller time-out.
3655 2012-09-22 Martin Rudalics <rudalics@gmx.at>
3657 * window.c (Fsplit_window_internal): Handle only Qt value of
3658 Vwindow_combination_limit separately.
3659 (Qtemp_buffer_resize): New symbol.
3660 (Vwindow_combination_limit): New default value.
3663 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3665 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
3666 the new overlay string. (Bug#10159)
3668 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3670 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
3671 or that fprintf is async-signal-safe. POSIX doesn't require
3674 2012-09-22 Chong Yidong <cyd@gnu.org>
3676 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
3679 2012-09-22 Kenichi Handa <handa@gnu.org>
3681 * composite.c (composition_reseat_it): Handle the case that a
3682 grapheme cluster is not covered by a single font (Bug#12352).
3684 2012-09-21 Chong Yidong <cyd@gnu.org>
3686 * image.c (define_image_type): Avoid adding duplicate types to
3687 image_types (Bug#12463). Suggested by Jörg Walter.
3689 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3691 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
3692 (print_load_command_name): Add case LC_DATA_IN_CODE.
3693 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
3695 2012-09-21 Glenn Morris <rgm@gnu.org>
3697 * eval.c (Frun_hook_with_args_until_success)
3698 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
3700 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
3702 * fileio.c (Ffile_selinux_context): Only call freecon when
3703 lgetfilecon succeeded.
3704 (Fset_file_selinux_context): Likewise. (Bug#12444)
3706 2012-09-21 Eli Zaretskii <eliz@gnu.org>
3708 * xdisp.c (try_window_reusing_current_matrix): Under bidi
3709 reordering, locate the cursor by calling set_cursor_from_row; if
3710 that fails, clear the desired glyph matrix before returning a
3711 failure indication to the caller. Fixes leaving garbled display
3712 when fast scrolling with a down-key. (Bug#12403)
3713 (compute_stop_pos_backwards): Fix a typo that caused crashes while
3714 scrolling through multibyte text.
3716 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
3718 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
3719 calling mark_vectorlike since that's the one that marks the window.
3720 (mark_discard_killed_buffers): Mark the final cdr.
3721 * window.h (struct window): Move prev/next_buffers to the
3722 non-standard fields.
3723 * window.c (make_window): Initialize prev/next_buffers manually.
3725 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
3727 Omit unused arg EXPECTED from socket hooks.
3728 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
3729 * nsterm.m (ns_term_init):
3730 * termhooks.h (struct terminal.read_socket_hook):
3731 * w32inevt.c (w32_console_read_socket):
3732 * w32term.c (w32_read_socket):
3733 * xterm.c (XTread_socket):
3734 Omit unused arg EXPECTED. All callers changed.
3735 (store_user_signal_events): Return void, not int, since callers no
3736 longer care about the return value. All uses changed.
3738 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
3740 * w32gui.h (XParseGeometry): Do not declare.
3742 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
3744 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
3745 Ignore 'expected'. See Eli Zaretskii in
3746 <http://bugs.gnu.org/12471#8> (last line).
3748 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
3749 (XParseGeometry): Now static. Substitute extremal values for
3750 values that are out of range.
3752 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
3754 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
3756 * nsfns.m (XParseGeometry): Remove.
3757 (Fx_create_frame): Call x_set_offset to correctly interpret
3758 top_pos in geometry.
3760 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
3761 (Fx_parse_geometry): If there is a space in string, call
3762 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
3764 2012-09-17 Eli Zaretskii <eliz@gnu.org>
3766 * search.c (scan_buffer): Use character positions in calls to
3767 region_cache_forward and region_cache_backward, not byte
3768 positions. (Bug#12196)
3770 * w32term.c (w32_read_socket): Set pending_signals to 1, like
3771 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
3773 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
3774 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
3775 emacs_blocked_malloc, now deleted.
3777 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
3779 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
3780 The workaround was for improving performance on Solaris 2.4, but
3781 is getting in the way now. Emacs will still work if someone is
3782 still running Solaris 2.4 in a museum somewhere; Sun dropped
3783 support for Solaris 2.4 in 2003.
3784 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
3785 * process.c (create_process) [HAVE_WORKING_VFORK]:
3786 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
3787 since Emacs no longer uses vfork on that platform.
3789 2012-09-17 Glenn Morris <rgm@gnu.org>
3791 * emacs.c: Use COPYRIGHT.
3793 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
3795 Remove configure's --without-sync-input option (Bug#12450).
3796 When auditing signal-handling in preparation for cleaning it up,
3797 I found that SYNC_INPUT has race conditions and would be a real
3798 pain to fix. Since it's an undocumented and deprecated
3799 configure-time option, now seems like a good time to remove it.
3800 Also see <http://bugs.gnu.org/11080#16>.
3801 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
3802 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
3803 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3804 (malloc_hysteresis):
3805 (check_depth) [XMALLOC_OVERRUN_CHECK]:
3806 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
3807 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
3808 (dont_register_blocks, bytes_used_when_reconsidered)
3809 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
3810 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
3811 [!SYSTEM_MALLOC && !SYNC_INPUT]:
3812 Remove. All uses removed.
3813 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
3814 implementation, one that depends on whether the new macro
3815 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
3817 * atimer.c (run_timers, handle_alarm_signal):
3818 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
3819 (handle_async_input, process_pending_signals)
3820 (handle_input_available_signal, init_keyboard):
3821 * nsterm.m (ns_read_socket):
3822 * process.c (wait_reading_process_output):
3823 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
3824 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
3826 * xterm.c (XTread_socket):
3828 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
3829 * eval.c (handling_signal): Remove. All uses removed.
3830 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
3831 All uses replaced with the SYNC_INPUT version.
3832 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
3834 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3837 * font.c (Ffont_shape_gstring): Remove unused local.
3839 2012-09-16 Glenn Morris <rgm@gnu.org>
3841 * Makefile.in (clean): No longer run nextstep's clean.
3843 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
3845 (ns-app): Move here from ns.mk, and simplify.
3846 (clean): Simplify nextstep entry.
3847 * ns.mk: Remove file.
3849 2012-09-17 Kenichi Handa <handa@gnu.org>
3851 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
3852 not covert the last few charactes.
3854 2012-09-16 Kenichi Handa <handa@gnu.org>
3856 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
3857 here, but just check the validity of glyphs in the glyph-string.
3859 2012-09-16 Martin Rudalics <rudalics@gmx.at>
3861 * window.c (Fwindow_parameter, Fset_window_parameter):
3862 Accept any window as argument (Bug#12452).
3864 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
3866 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
3867 to ns_term_init to avoid memory leak.
3869 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
3870 explicit retain/release.
3871 (ns_term_init): Only allow one display. Initialize outerpool and
3874 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3876 Port _setjmp fix to POSIXish hosts as well as Microsoft.
3877 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
3878 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
3879 the Microsoft problem in a different way, by altering ../nt/config.nt.
3881 2012-09-15 Eli Zaretskii <eliz@gnu.org>
3896 * w16select.c: Remove inclusion of setjmp.h, as it is now included
3897 by lisp.h. This completes removal of setjmp.h inclusion
3898 erroneously announced in the previous commit. (Bug#12446)
3900 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
3903 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
3904 not defined as a macro. The latter happens on MS-Windows.
3907 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3909 Port better to POSIX hosts lacking _setjmp (Bug#12446).
3910 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
3911 Some instances of '#include <setjmp.h>' removed, if the
3912 only reason for the instance was because "lisp.h" was included.
3913 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
3914 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
3915 and _longjmp with the new symbols. Emacs already uses _setjmp if
3916 available, so this change affects only POSIXish hosts that have
3917 sigsetjmp but not _setjmp, such as some versions of Solaris and
3918 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
3919 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
3920 (png_load_body) [HAVE_PNG]:
3921 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
3922 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
3923 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
3924 since PNG requires jmp_buf. This is the only exception to the
3925 general rule that we now use sys_setjmp and sys_longjmp.
3926 This exception is OK since this code does not change the signal
3927 mask or longjmp out of a signal handler.
3929 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
3931 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3932 Include "syssignal.h", for 'main_thread'.
3934 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
3936 Avoid out-of-range marker position (Bug#12426).
3937 * insdel.c (replace_range, replace_range_2):
3938 Adjust markers before overlays, as suggested by comments.
3939 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
3940 Remove redundant check before calling offset_intervals.
3942 2012-09-14 Martin Rudalics <rudalics@gmx.at>
3944 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
3945 current buffer (Bug#12387).
3947 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
3949 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
3951 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3953 Use a more backwards-compatible timer format (Bug#12430).
3954 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
3955 vector element, not from the 4th, since PSECS is now at the end.
3956 (Fcurrent_idle_time): Doc fix.
3958 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
3960 Function to mark objects and remove killed buffers at once.
3961 * alloc.c (discard_killed_buffers): Rename to ...
3962 (mark_discard_killed buffers) ... new name. Add marking
3963 of remaining objects. Fix comment. Adjust users.
3964 (mark_object): Do not touch frame buffer lists here.
3965 * frame.c (delete_frame): Reset frame buffer lists here.
3967 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3969 Better workaround for GNOME bug when --enable-gcc-warnings.
3970 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
3971 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
3972 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
3974 Simplify SIGIO usage (Bug#12408).
3975 The code that dealt with SIGIO was crufty and confusing, e.g., it
3976 played tricks like "#undef SIGIO" but these tricks were not used
3977 consistently. Simplify mostly by not #undeffing standard symbols,
3978 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
3979 or not as we please) rather than "defined SIGIO" (standard symbol
3980 that we probably shouldn't #undef).
3981 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
3982 Modules that need it can include it.
3983 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
3984 * dispextern.h (ignore_sigio): New decl.
3985 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
3986 unconditionally, since it's now a no-op if !USABLE_SIGIO.
3987 * emacs.c (shut_down_emacs):
3988 * keyboard.c (kbd_buffer_store_event_hold):
3989 Use ignore_sigio rather than invoking 'signal' directly.
3990 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
3992 (FIONREAD, SIGIO): Do not #undef.
3993 (tty_read_avail_input): Use #error rather than a syntax error.
3994 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
3995 for I_PIPE, used by SETUP_SLAVE_PTY.
3996 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
3997 * sysdep.c (croak): Remove; no longer needed. This bit of
3998 temporary code, with Fred N. Fish's comment that it's temporary,
3999 has been in Emacs since at least 1992!
4000 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
4001 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
4002 * syssignal.h (croak): Remove decl.
4003 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
4004 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
4005 now that we're termios-only.
4006 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
4007 * term.c (dissociate_if_controlling_tty): Use #error rather than
4010 Work around GCC and GNOME bugs when --enable-gcc-warnings.
4011 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
4012 to work around GNOME bug 683906.
4013 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
4014 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
4015 This works around GCC bug 54561.
4017 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4019 More fixes for 'volatile' and setjmp/longjmp.
4020 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
4021 * image.c (struct png_load_context) [HAVE_PNG]: New type.
4022 (png_load_body) [HAVE_PNG]:
4023 (jpeg_load_body) [HAVE_JPEG]:
4024 New function, with most of the old parent function's body.
4025 (png_load) [HAVE_PNG]:
4026 (jpeg_load) [HAVE_JPEG]:
4027 Invoke the new function, to avoid longjmp munging our locals.
4028 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
4029 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
4030 longjmp is passed 2, as the C standard doesn't guarantee this.
4031 Instead, store the failure code into mgr->failure_code.
4033 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4035 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
4036 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
4037 (syms_of_keyboard): Remove support for unread-command-char.
4039 2012-09-12 Eli Zaretskii <eliz@gnu.org>
4041 * w32proc.c (sys_kill): If PID is our process ID and the signal is
4042 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
4043 violation. (Bug#12426)
4045 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4047 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
4049 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4051 * eval.c: Add `inhibit-debugger'.
4052 (Qinhibit_debugger): New symbol.
4053 (call_debugger): Bind it instead of Qdebug_on_error.
4054 (maybe_call_debugger): Test Vinhibit_debugger.
4055 (syms_of_eval): Define inhibit-debugger.
4056 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
4057 (syms_of_xdisp): Remove inhibit-debug-on-message.
4059 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4061 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
4062 If a nonvolatile local variable is written before a _longjmp to
4063 the frame containing the variable, and is read after the _longjmp,
4064 the value read is indeterminate. Some local variables of type
4065 'struct handler' and 'struct catchtag' are used in this way, so
4066 mark each of their slots as volatile if the slot can be set before
4067 _longjmp and read afterwards.
4068 * lisp.h (struct handler): var and chosen_clause are now volatile.
4069 (struct catchtag): val, next, and pdlcount are now volatile.
4071 * bidi.c (bidi_push_it, bidi_pop_it):
4072 * fns.c (copy_hash_table):
4073 * image.c (define_image_type):
4074 * keyboard.c (kbd_buffer_store_event_hold):
4075 * process.c (Fprocess_send_eof):
4076 * xfaces.c (x_create_gc) [HAVE_NS]:
4077 * xgselect.c (xg_select):
4078 Prefer assignment to memcpy when either will do.
4080 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
4081 Use pointer-to-a-pointer to simplify and avoid a NILP check each
4082 time an item is removed. No need to mark this function 'inline';
4083 the compiler knows better than we do.
4085 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
4087 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
4088 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
4089 to change_frame_size (Bug#12388).
4090 (windowDidResize:): Pass YES to updateFrameSize.
4092 * nsterm.h: Add delay parameter to updateFrameSize.
4094 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4096 Discard killed buffers from deleted window and frame objects.
4097 This reduces an amount of references to killed buffers and
4098 helps GC to reclaim them faster.
4099 * alloc.c (discard_killed_buffers): New function.
4100 (mark_object): Use it for deleted windows and frames.
4101 (mark_object): If symbol's value is set up for a killed buffer
4102 or deleted frame, restore its global binding.
4103 * data.c (swap_in_global_binding): Add GC notice.
4104 (swap_in_symval_forwarding): Use convenient set_blv_where.
4105 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
4106 * window.h: ... to here.
4108 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4110 Convenient macro to check whether the buffer is live.
4111 * buffer.h (BUFFER_LIVE_P): New macro.
4112 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
4113 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
4115 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4117 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
4118 composition cases (Bug#12364).
4120 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
4121 overhang of succeeding glyphs overlapping box cursor.
4123 * w32term.c (x_draw_glyph_string): Likewise.
4125 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4127 Simplify, document, and port floating-point (Bug#12381).
4128 The porting part of this patch fixes bugs on non-IEEE platforms
4129 with frexp, ldexp, logb.
4130 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
4132 * floatfns.c: Simplify discussion of functions that Emacs doesn't
4133 support, by removing commented-out code and briefly listing the
4134 C89 functions excluded. The commented-out stuff was confusing
4135 maintenance, e.g., we thought we needed cbrt but it was commented out.
4136 (logb): Remove decl; no longer needed.
4137 (isfinite): New macro, if not already supplied.
4138 (isnan): Don't replace any existing macro.
4139 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
4140 are present on all C89 platforms.
4141 (Ffrexp): Do not special-case zero, as frexp does the right thing
4143 (Flogb): Do not use logb, as it doesn't have the desired meaning
4144 on hosts that use non-base-2 floating point. Instead, stick with
4145 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
4146 frexp, to avoid getting an unspecified result.
4148 * xdisp.c (Qinhibit_debug_on_message): Now static.
4150 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
4152 * nsterm.m (ns_update_begin): Set clip path to whole view by using
4153 NSBezierPath (Bug#12131).
4155 2012-09-10 Chong Yidong <cyd@gnu.org>
4157 * fns.c (Fdelq, Fdelete): Doc fix.
4159 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
4161 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
4162 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
4164 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
4166 * lisp.h (make_lisp_ptr): New macro to replace XSET.
4167 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
4170 2012-09-09 Eli Zaretskii <eliz@gnu.org>
4172 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
4173 left fringe if the window has a left margin. This avoids leaving
4174 traces of the cursor because its leftmost pixel is not drawn over.
4176 * dispnew.c (update_window_line): When the left margin area of a
4177 screen line is updated, set the redraw_fringe_bitmaps_p flag of
4178 that screen line. (Bug#12277)
4180 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
4182 Assume C89 or later for math functions (Bug#12381).
4183 This simplifies the code, and makes it a bit smaller and faster,
4184 and (most important) makes it easier to clean up signal handling
4185 since we can stop worring about floating-point exceptions in
4186 library code. That was a problem before C89, but the problem
4187 went away many years ago on all practical Emacs targets.
4188 * data.c, image.c, lread.c, print.c:
4189 Don't include <math.h>; no longer needed.
4190 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
4191 might be autoconfigured, as that never happens.
4193 * doprnt.c (DBL_MAX_10_EXP):
4194 * print.c (DBL_DIG):
4195 Remove. C89 or later always defines these.
4196 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
4197 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
4198 (arith_error, domain_error, domain_error2):
4199 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
4200 no longer needed -- we simply return what C returns. All uses removed.
4201 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
4203 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
4204 Remove. All uses expanded, as these macros are no longer used
4205 more than once and are now more trouble than they're worth.
4206 (Ftan): Use tan, not sin / cos.
4207 (Flogb): Assume C89 frexp.
4208 (fmod_float): Assume C89 fmod.
4209 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
4210 (init_floatfns): Remove. All uses removed.
4212 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4214 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
4215 compositeToPoint for OSX < 10.6 (Bug#12390).
4217 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
4219 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
4220 This produces more-accurate results.
4222 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4224 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
4225 changes (Bug#12088).
4227 2012-09-08 Chong Yidong <cyd@gnu.org>
4229 * syntax.c (Fstring_to_syntax): Doc fix.
4231 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4233 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
4234 in the internal border.
4235 (x_set_window_size): Remove static variables and their usage.
4236 (ns_redraw_scroll_bars): Fix NSTRACE arg.
4237 (ns_after_update_window_line, ns_draw_fringe_bitmap):
4238 Remove fringe/internal border adjustment (Bug#11052).
4239 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
4240 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
4241 (ns_fix_rect_ibw): Remove.
4242 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
4243 (ns_dumpglyphs_box_or_relief): Ditto.
4244 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
4246 (ns_dumpglyphs_image): Ditto.
4247 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
4249 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
4250 their usage. Add fringe_extended_p and its use as in other terms.
4251 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
4252 scroll bar was removed.
4253 (updateFrameSize): New function.
4254 (windowDidResize): Move code to updateFrameSize and call it.
4256 * nsterm.h (EmacsView): Add updateFrameSize.
4258 2012-09-07 Chong Yidong <cyd@gnu.org>
4260 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
4262 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
4264 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4266 More signal-handler cleanup (Bug#12327).
4267 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
4268 Problem introduced when merging patches. Noted by Eli Zaretskii in
4269 <http://bugs.gnu.org/12327#67>.
4270 * floatfns.c: Comment fix.
4271 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
4272 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
4273 and anyway the declaration is harmless even if SIGDANGER is not defined.
4274 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
4275 defined BROKEN_FIONREAD). systty.h formerly did this, but other
4276 source files not surprisingly expected syssignal.h to define, or
4277 not define, SIGIO, and it's cleaner to do it that way, for consistency.
4278 Include <sys/ioctl.h>, for FIONREAD.
4279 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
4280 This eliminates a problem whereby other files mysteriously had
4281 to include "syssignal.h" before including "systty.h" if they
4282 wanted to use "#ifdef SIGIO".
4284 2012-09-07 Eli Zaretskii <eliz@gnu.org>
4286 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
4288 * w32.c (sigemptyset): Empty the set.
4289 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
4291 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
4293 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
4295 * alloc.c (mark_buffer): Revert unsafe marking optimization.
4296 (mark_object): Likewise for frame objects.
4298 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4300 * syssignal.h (handle_on_main_thread): Always declare,
4301 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
4302 This ports to platforms without HAVE_PTHREAD.
4304 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4306 Signal-handler cleanup (Bug#12327).
4307 Emacs's signal handlers were written in the old 4.2BSD style with
4308 sigblock and sigmask and so forth, and this led to some
4309 inefficiencies and confusion. Rewrite these to use
4310 pthread_sigmask etc. without copying signal sets around. Also,
4311 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
4312 'signal', and instead use functions that do not attempt to take
4313 over the system name space. This patch causes Emacs's text
4314 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
4315 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
4316 Do not include <signal.h> or "syssignal.h", as these
4317 modules do not use signals.
4318 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
4319 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
4320 Do not include <signal.h>, as "syssignal.h" does that for us now.
4321 * atimer.c (sigmask_atimers): New function.
4322 (block_atimers, unblock_atimers): New functions,
4323 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
4325 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
4326 no longer needed here.
4327 * emacs.c (main): Inspect existing signal handler with sigaction,
4328 so that there's no need to block and unblock SIGHUP.
4329 * sysdep.c (struct save_signal): New member 'action', replacing
4330 old member 'handler'.
4331 (save_signal_handlers, restore_signal_handlers):
4332 Use sigaction instead of 'signal' to save and restore.
4333 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
4334 New function. All users of 'signal' modified to use set_sighandler
4335 if they're writeonly, and to use sys_signal if they're read+write.
4336 (emacs_sigaction_init, forwarded_signal): New functions.
4337 (sys_signal): Remove. All uses replaced by calls to sigaction
4338 and emacs_sigaction_init, or by direct calls to 'signal'.
4339 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
4340 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
4341 all uses replaced by pthread_sigmask etc. calls.
4342 * syssignal.h: Include <signal.h>.
4343 (emacs_sigaction_init, forwarded_signal): New decls.
4344 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
4345 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
4346 (sigmask, sys_sigmask): Remove; no longer needed.
4347 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
4348 (sigblock, sigunblock, sigfree):
4349 (sigsetmask) [!defined sigsetmask]:
4350 Remove. All uses replaced by pthread_sigmask.
4351 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
4352 no longer need to be replaced, and its typical old uses
4353 are now done via emacs_sigaction_init and sigaction.
4354 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
4355 (sys_sigdel): Remove; unused.
4356 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
4358 2012-09-06 Eli Zaretskii <eliz@gnu.org>
4360 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
4361 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
4363 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4365 Explicitly mark buffer_defaults and buffer_local_symbols.
4366 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
4367 mark_local_symbols here.
4368 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
4369 since special buffers aren't marked here any more.
4370 (allocate_buffer): Chain new buffer with all_buffers here...
4371 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
4373 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
4374 (syms_of_buffer): Remove staticpro of the above.
4375 (init_buffer_once): Set names for buffer_defaults and
4376 buffer_local_symbols.
4378 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4380 Use bool for booleans in font-related modules.
4381 * font.c (font_intern_prop, font_style_to_value)
4382 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
4383 (generate_otf_features, font_check_otf_features, font_check_otf)
4384 (font_match_p, font_list_entities, font_at):
4385 * fontset.c (fontset_id_valid_p, reorder_font_vector
4386 (fontset_find_font, Fset_fontset_font)
4387 (face_suitable_for_char_p) [0]:
4388 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
4389 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
4390 (m17n_flt_initialized, ftfont_shape_by_flt):
4391 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
4392 * nsfont.m (nsfont_draw):
4393 * w32font.c (w32font_draw):
4394 * w32term.c (x_draw_glyphless_glyph_string_foreground):
4395 Use bool for booleans.
4396 * font.h: Adjust to above API changes.
4397 (struct font, struct font_driver, struct font_driver_list):
4398 Use bool for booleans.
4399 (struct font): Remove useless member encoding_type.
4401 * fontset.c, xftfont.c: Omit unnecessary static decls.
4403 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4405 * alloc.c (mark_object): Revert window marking code
4406 since it's unsafe for the Fset_window_configuration.
4408 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4410 Fix race conditions with signal handlers and errno (Bug#12327).
4411 Be more systematic about preserving errno whenever a signal
4412 handler returns, even if it's not in the main thread. Do this by
4413 renaming signal handlers to distinguish between signal delivery
4414 and signal handling. All uses changed.
4415 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
4416 * data.c (deliver_arith_signal): Rename from arith_error.
4417 * dispnew.c (deliver_window_change_signal): Rename from
4418 window_change_signal.
4419 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
4420 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
4421 * keyboard.c (deliver_input_available_signal): Rename from
4422 input_available_signal.
4423 (deliver_user_signal): Rename from handle_user_signal.
4424 (deliver_interrupt_signal): Rename from interrupt_signal.
4425 * process.c (deliver_pipe_signal): Rename from send_process_trap.
4426 (deliver_child_signal): Rename from sigchld_handler.
4427 * atimer.c (handle_alarm_signal):
4428 * data.c (handle_arith_signal):
4429 * dispnew.c (handle_window_change_signal):
4430 * emacs.c (handle_fatal_signal, handle_danger_signal):
4431 * keyboard.c (handle_input_available_signal):
4432 * keyboard.c (handle_user_signal, handle_interrupt_signal):
4433 * process.c (handle_pipe_signal, handle_child_signal):
4434 New functions, with the actual signal-handling code taken from the
4435 original respective signal handlers, sans the sporadic attempts to
4436 preserve errno, since that's now done by handle_on_main_thread.
4437 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
4438 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
4439 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4441 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4442 Move initialization of main_thread to sysdep.c's init_signals.
4443 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
4444 our usage, and simplifies the mainline code.
4445 (record_child_status_change): New static function, as a helper
4446 for handle_child_signal, and with most of the old child handler's
4448 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
4449 (handle_child_signal): Use the above.
4450 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4451 Moved here from emacs.c.
4452 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
4453 code moved here from emacs.c's main function.
4454 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
4455 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
4456 This lets callers save and restore errno properly.
4458 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4460 Remove redundant or unused things here and there.
4461 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
4462 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
4463 * editfns.c (Fcompare_buffer_substrings): Likewise.
4464 * frame.h (struct terminal, struct font_driver_list):
4465 Remove redundant declarations.
4466 * window.h (Qleft, Qright): Likewise.
4468 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4470 Do not mark objects from deleted buffers, windows and frames.
4471 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
4472 (mark_object): Likewise for windows and frames.
4474 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4476 * alloc.c (valid_lisp_object_p): Treat killed buffers,
4477 buffer_defaults and buffer_local_symbols as valid objects.
4478 Return special value to denote them.
4480 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4482 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
4483 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
4484 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
4485 (file_name_absolute_p, Fsubstitute_in_file_name):
4486 (check_executable, check_writable, Ffile_accessible_directory_p)
4487 (Fset_file_selinux_context, Fdefault_file_modes)
4488 (Finsert_file_contents, choose_write_coding_system)
4489 (Fwrite_region, build_annotations, a_write, e_write)
4491 * filelock.c (boot_time_initialized, get_boot_time)
4492 (get_boot_time_1, lock_file_1, within_one_second):
4493 * floatfns.c (in_float):
4494 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
4495 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
4496 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
4497 * lisp.h (struct Lisp_Hash_Table.cmpfn):
4498 * window.c (compare_window_configurations):
4499 Use bool for booleans.
4500 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
4501 (Fdefault_file_modes): Now mode_t, not int, for modes.
4502 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
4503 (internal_delete_file): Now returns void, not a (boolean) int,
4504 since nobody was looking at the return value.
4505 * lisp.h, window.h: Adjust to above API changes.
4507 * xdisp.c (set_message): Simplify and reindent last change.
4509 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
4511 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
4513 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
4515 * eval.c (call_debugger): Make the function non-static so that we
4516 can call it from set_message.
4518 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
4519 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
4521 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4523 Give more-useful info on a fatal error (Bug#12328).
4524 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
4525 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
4526 of doing the work ourselves.
4527 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
4528 do most of the work.
4529 (fatal_error_backtrace): New function, taken from the guts
4530 of the old fatal_error_signal, but with a new option to output
4532 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
4533 info about the signal than just its number.
4534 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
4535 * sysdep.c: Include <execinfo.h>
4536 (emacs_backtrace): New function, taken partly from the previous
4537 code of the 'die' function.
4538 (emacs_abort): Call fatal_error_backtrace rather than abort.
4540 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
4542 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
4543 eager (load-time) macro-expansion.
4544 * lisp.mk (lisp): Add macroexp.
4546 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4548 Simplify redefinition of 'abort' (Bug#12316).
4549 Do not try to redefine the 'abort' function. Instead, redo
4550 the code so that it calls 'emacs_abort' rather than 'abort'.
4551 This removes the need for the NO_ABORT configure-time macro
4552 and makes it easier to change the abort code to do a backtrace.
4553 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
4554 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
4555 Remove; sysdep.c's emacs_abort now takes its place.
4556 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
4557 'abort' changed to use 'emacs_abort'.
4558 * msdos.c (dos_abort) [defined abort]: Remove; not used.
4559 (abort) [!defined abort]: Rename to ...
4560 (emacs_abort): ... new name.
4561 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
4562 the place of the old 'abort' in emacs.c.
4563 * w32.c, w32fns.c (abort): Do not #undef.
4564 * w32.c (emacs_abort): Rename from w32_abort.
4566 2012-09-04 Eli Zaretskii <eliz@gnu.org>
4568 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
4569 offsets[j].dv, since the y axis of the screen coordinates points

4571 up. This fixes display of Arabic diacritics such as KASRA and
4572 KASRATAN. (Bug#11860)
4574 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4576 Be more systematic about _setjmp vs setjmp.
4577 * alloc.c (test_setjmp, mark_stack):
4578 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
4579 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
4580 (png_load, my_error_exit, jpeg_load):
4581 * process.c (send_process_trap, send_process):
4582 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
4583 The underscored versions are up to 30x faster on some hosts.
4584 Formerly, the code used setjmp+longjmp sometimes and
4585 _setjmp+_longjmp at other times, with no particular reason to
4586 prefer setjmp+longjmp.

4623 * msdos.c (fatal_error_in_progress): ... from here.

4627 REDISPLAYING_P when unwinding, instead of saving its previous,
4628 always-false value and then restoring it.
4630 Clean up some extern decls.
4631 Mostly, this hoists extern decls out of .c files and into .h files.
4632 That way, we're more likely to catch errors if the interfaces change.
4633 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
4634 declare xg_mark_data.

4656 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
4657 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
4659 * xfaces.c: Remove unnecessary static decls.
4660 * xterm.c (updating_frame): Remove decl of nonexistent object.
4662 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
4663 when building globals.h, as the objects that are not built on
4664 this host are not needed to compile C files on this host.

4718 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
4719 more than one grapheme cluster passed to the shaper: compute the
4720 offset adjustment values separately for each cluster. (Bug#11860)
4722 * image.c: Restore mistakenly removed inclusion of w32.h. Without
4723 it, GCC doesn't see prototypes of w32_delayed_load, and complains
4724 about implicit conversions from integer to pointer.
4726 2012-09-01 Daniel Colascione <dancol@dancol.org>
4728 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
4729 system used too early.

4782 window system declarations.
4784 * frame.h: Move common functions here: set_frame_menubar,
4785 x_set_window_size, x_sync, x_get_focus_frame,
4786 x_set_mouse_position, x_set_mouse_pixel_position,
4787 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

4873 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
4874 Add window_closed and button_values. Add void as return value for
4875 add(Button|String|Split). addButton takes int instead of Lisp_Object.

5017 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
5018 not a boolean 'int', since callers never look at the return value.
5019 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
5020 * coding.h (decoding_buffer_size, encoding_buffer_size)
5021 (emacs_mule_string_char): Remove unused extern decls.
5022 (struct iso_2022_spec, struct coding_system):
5023 Use 'unsigned int : 1' for boolean fields, since there's more than one.
5024 (struct emacs_mule_spec): Remove unused field 'full_support'.
5025 All initializations removed.
5026 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
5028 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
5030 Fix spare memory change (Bug#12286).
5031 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
5032 (valid_lisp_object_p): Likewise.
5034 2012-08-27 Martin Rudalics <rudalics@gmx.at>
5036 * window.c (Fset_window_configuration): Record any window's old
5037 buffer if it's replaced (see Bug#8789). If the new current
5038 buffer doesn't appear in the selected window, go to its old
5041 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
5043 Special MEM_TYPE_SPARE to denote reserved memory.
5044 * alloc.c (enum mem_type): New memory type.
5045 (refill_memory_reserve): Use new type for spare memory.
5046 This prevents live_cons_p and live_string_p from incorrect
5047 detection of uninitialized objects from spare memory as live.
5049 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
5052 * Makefile.in (.PHONY): versioclean -> versionclean.
5054 Remove unused external symbols.
5055 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
5056 * window.c (Qwindow_valid_p, decode_valid_window):
5057 Now static, not extern.
5058 * data.c (Qinterval): Remove; unused.
5059 (syms_of_data): Do not define 'interval'.
5060 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
5061 * window.h (decode_valid_window):
5064 * character.c, charset.c, chartab.c: Use bool for booleans.
5065 * character.c (lisp_string_width, string_count_byte8)
5066 (string_escape_byte8):
5067 * charset.c (charset_map_loaded, load_charset_map, read_hex):
5068 (load_charset_map_from_file, map_charset_chars)
5069 (Fdefine_charset_internal, define_charset_internal)
5070 (Fdeclare_equiv_charset, find_charsets_in_text)
5071 (Ffind_charset_region, char_charset, Fiso_charset):
5072 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
5073 (sub_char_table_set, sub_char_table_set_range)
5074 (char_table_set_range, optimize_sub_char_table)
5075 (map_sub_char_table):
5076 Use bool for boolean.
5077 * character.c (str_to_unibyte): Omit last boolean argument; it was
5078 always 0. All callers changed.
5079 * character.h, charset.h: Adjust to match previous changes.
5080 * character.h (char_printable_p): Remove decl of nonexistent function.
5081 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
5082 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
5083 are all boolean, so make them single-bit bitfields.
5085 * lisp.h (ASET): Remove attempt to detect side effects.
5086 It was meant to be temporary and it often doesn't work,
5087 because when IDX has side effects the behavior of IDX==IDX
5088 is undefined. See Stefan Monnier in
5089 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
5091 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
5093 * lisp.h (functionp): New function (extracted from Ffunctionp).
5094 (FUNCTIONP): Use it.
5095 * eval.c (Ffunctionp): Use it.
5097 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
5099 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
5100 as that's faster and simpler than static storage. Don't bother
5101 with the g_main_context_query overhead if g_main_context_pending
5102 says no events are pending.
5103 (gfds, gfds_size): Remove these static vars.
5104 (xgselect_initialize): Remove; no longer needed.
5105 All uses and decls removed.
5107 * emacs.c (fatal_error_signal_hook): Remove.
5108 All uses removed. This leftover from old code was always 0.
5110 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
5111 * casefiddle.c (casify_object, casify_region):
5112 * casetab.c (set_case_table):
5113 * category.c, category.h (word_boundary_p):
5114 * category.h (CHAR_HAS_CATEGORY):
5115 Use bool for booleans, instead of int.
5117 2012-08-25 Eli Zaretskii <eliz@gnu.org>
5119 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
5121 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
5123 On assertion failure, print backtrace if available.
5124 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
5125 (die) [ENABLE_CHECKING]: Print a backtrace if available.
5126 * Makefile.in (LIB_EXECINFO): New macro.
5129 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
5130 * bytecode.c (exec_byte_code):
5131 * callint.c (check_mark, Fcall_interactively):
5132 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
5133 (getenv_internal, sync_process_alive, call_process_exited):
5134 * lisp.h (USE_SAFE_ALLOCA):
5135 Use bool for booleans, instead of int.
5136 * lisp.h, process.h: Adjust prototypes to match above changes.
5137 * callint.c (Fcall_interactively): Don't assume the mark's
5138 offset fits in 'int'.
5140 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
5142 * buffer.c, buffer.h: Use bool for boolean.
5143 * buffer.c (reset_buffer_local_variables)
5144 (buffer_lisp_local_variables, Fset_buffer_modified_p)
5145 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
5146 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
5147 (overlay_touches_p, overlay_strings, Foverlay_put)
5148 (report_overlay_modification, call_overlay_mod_hooks):
5149 (mmap_enlarge, mmap_set_vars):
5150 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
5151 Use bool for booleans, instead of int.
5152 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
5153 since the 1-or-0 return value is always ignored anyway.
5154 (mmap_initialized_p):
5155 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
5156 * buffer.h, lisp.h: Adjust prototypes to match above changes.
5158 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5160 * bidi.c: Use bool for boolean.
5161 This is a bit more readable, and makes the text segment of bidi.o
5162 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
5163 Presumably it's faster too.
5164 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
5166 (bidi_cache_find_level_change, bidi_cache_iterator_state)
5167 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
5168 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
5169 (bidi_explicit_dir_char, bidi_level_of_next_char)
5170 (bidi_find_other_level_edge, bidi_move_to_visually_next):
5171 Use bool for booleans, instead of int.
5172 * dispextern.h (bidi_init_it, bidi_paragraph_init)
5173 (bidi_unshelve_cache): Adjust decls to match code.
5175 2012-08-23 Martin Rudalics <rudalics@gmx.at>
5177 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
5180 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5182 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
5183 * atimer.h: Include <stdbool.h>.
5185 2012-08-22 Dan Nicolaescu <dann@gnu.org>
5187 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
5188 compile time tests instead of run time tests on systems that do
5190 (FRAME_MAC_P): Remove leftover from deleted code.
5191 * frame.c (syms_of_frame): Remove leftover from deleted code.
5193 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
5195 * nsterm.m (insertText:): Don't clear modifiers if code is space.
5197 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
5199 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
5200 Otherwise, the compiler complains about (A?B:C) where B is void
5201 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
5202 (fontset_add): Return void, for FONTSET_ADD.
5204 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5206 * alloc.c: Use bool for booleans.
5207 (gc_in_progress, abort_on_gc)
5208 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5209 (dont_register_blocks) [GC_MALLOC_CHECK]:
5210 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
5211 (check_string_bytes, make_specified_string, memory_full)
5212 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
5213 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
5214 (mark_stack, valid_pointer_p, make_pure_string)
5215 (Fgarbage_collect, survives_gc_p, gc_sweep):
5216 Use bool for booleans, instead of int.
5217 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5218 Remove unused local.
5219 * alloc.c (PURE_POINTER_P):
5220 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
5221 * editfns.c (Fformat):
5222 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
5224 * fns.c (sweep_weak_table):
5225 * lisp.h (suppress_checking, push_message, survives_gc_p)
5226 (make_pure_string, gc_in_progress, abort_on_gc):
5227 * lread.c (readchar, read1):
5228 * print.c (Fprin1_to_string):
5229 * xdisp.c (push_message):
5230 Use bool for booleans affected directly or indirectly by
5233 Make recently-introduced setters macros.
5234 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
5235 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
5236 (set_fontset_default, set_fontset_fallback): Rename from their
5237 upper-case counterparts, and make them functions rather than macros.
5238 This is more consistent with the other recently-introduced setters.
5239 These don't need to be inline, since they're local.
5241 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
5243 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
5244 the loop (Bug#12247).
5246 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5248 * lisp.h (vcopy): Use memcpy rather than our own loop.
5249 This fixes a performance regression introduced by the recent
5250 addition of vcopy. This means 'vcopy' will need to be modified
5251 for a copying collector, but that's OK. Also, tighten the
5252 checking in the assertion.
5254 2012-08-21 Eli Zaretskii <eliz@gnu.org>
5256 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
5257 components for RTL text (Bug#11860). Adjust X-OFFSET of each
5258 non-base glyph for the width of the base character, according to
5259 what x_draw_composite_glyph_string_foreground expects.
5260 Generate WADJUST value according to composition_gstring_width's
5261 expectations, to produce correct width of the composed character.
5262 Reverse the sign of the DU offset produced by ScriptPlace.
5264 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5266 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
5268 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
5270 Avoid direct writes to contents member of struct Lisp_Vector.
5271 * lisp.h (vcopy): New function to copy data into vector.
5272 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
5273 * fns.c (Ffillarray): Use ASET.
5274 * keyboard.c (timer_check_2): Use AREF and ASET.
5275 (append_tool_bar_item, Frecent_keys): Use vcopy.
5276 * lread.c (read_vector): Use ASET.
5277 * msdos.c (Frecent_doskeys): Use vcopy.
5278 * xface.c (Finternal_copy_lisp_face): Use vcopy.
5279 (Finternal_merge_in_global_face): Use ASET and vcopy.
5280 * xfont.c (xfont_list_pattern): Likewise.
5282 2012-08-21 Martin Rudalics <rudalics@gmx.at>
5284 * window.c (Fwindow_point): For the selected window always return
5285 the position of its buffer's point.
5286 (Fset_window_point): For the selected window always go in its
5287 buffer to the specified position.
5289 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
5291 Setter macros for fontsets.
5292 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
5293 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
5294 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
5297 2012-08-20 Glenn Morris <rgm@gnu.org>
5299 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
5300 Don't assume that `ln -f' works.
5302 2012-08-20 Eli Zaretskii <eliz@gnu.org>
5304 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
5305 and later about non-assignments with no effect. See discussion at
5306 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
5309 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5311 Inline setter functions for Lisp_Objects slots of struct specbinding.
5312 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
5315 2012-08-20 Martin Rudalics <rudalics@gmx.at>
5317 * window.c (select_window): Always make selected window's buffer
5320 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5322 Use AREF and ASET for docstrings of category tables.
5323 * category.h (CATEGORY_DOCSTRING): Use AREF.
5324 (SET_CATEGORY_DOCSTRING): Use ASET.
5325 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
5327 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5329 Inline setter functions for hash table members.
5330 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
5331 (set_hash_hash, set_hash_index): Rename with _slot suffix.
5332 (set_hash_key_and_value, set_hash_index, set_hash_next)
5333 (set_hash_hash): New functions.
5334 * charset.c, fns.c: Adjust users.
5336 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5338 Inline getter and setter functions for per-buffer values.
5339 * buffer.h (per_buffer_default, set_per_buffer_default)
5340 (per_buffer_value, set_per_buffer_value): New functions.
5341 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
5342 * buffer.c, data.c: Adjust users.
5344 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
5346 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
5348 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
5350 Rely on <config.h> + <unistd.h> to declare 'environ',
5351 as gnulib does this if the system doesn't.
5352 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
5353 Remove declaration. MS-Windows declares it on stdlib.h which is
5354 included by conf_post.h.
5355 * emacs.c (environ) [DOUG_LEA_MALLOC]:
5356 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
5357 * vm-limit.c: Include <unistd.h>, for 'environ'.
5359 * unexaix.c, unexcoff.c: Include "mem-limits.h".
5360 (start_of_data): Remove decl; mem-limits.h provides it.
5362 * xdisp.c (handle_invisible_prop): Make it a bit faster
5363 and avoid a gcc -Wmaybe-uninitialized diagnostic.
5365 2012-08-19 Chong Yidong <cyd@gnu.org>
5367 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
5370 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
5372 * .gdbinit: Use call instead of set when calling a function in the
5375 * data.c (set_internal): Don't use set_blv_found.
5376 (Fkill_local_variable): Likewise.
5378 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
5380 * nsfont.m (ns_ascii_average_width): Ensure the string
5381 ascii_printable is initialized with a null-terminated character
5382 array. Otherwise, it can contain undesired extra characters.
5384 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
5386 port new setting code to Sun C 5.8 2005/10/13
5387 * chartab.c, lisp.h (char_table_set, char_table_set_range):
5388 Return void, not Lisp_Object. Otherwise, the compiler
5389 complains about (A?B:C) where B is void and C is Lisp_Object
5390 when compiling CHAR_TABLE_SET, due to the recent change to
5391 the API of sub_char_table_set_contents.
5393 2012-08-18 Chong Yidong <cyd@gnu.org>
5395 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
5396 for the string case (Bug#3874).
5398 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
5400 * buffer.h (BSET): Remove (Bug#12215).
5401 Replace all uses with calls to new setter functions.

5429 * category.c (bset_category_table):
5430 * syntax.c (bset_syntax_table):
5431 New setter functions.
5433 * process.h (PSET): Remove (Bug#12215).
5434 Replace all uses with calls to new setter functions.
5435 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
5436 (PROCESS_INLINE): New macro.
5437 (pset_childp): New setter function.
5438 (pset_gnutls_cred_type) [HAVE_GNUTLS]: New setter function.
5439 * process.c (PROCESS_INLINE):
5440 Define to EXTERN_INLINE, so that the corresponding functions
5441 are compiled into code.
5442 (pset_buffer, pset_command, pset_decode_coding_system)
5443 (pset_decoding_buf, pset_encode_coding_system)

5445 (pset_plist, pset_sentinel, pset_status, pset_tty_name)
5446 (pset_type, pset_write_queue): New setter functions.
5448 * window.h (WSET): Remove (Bug#12215).
5449 Replace all uses with calls to new setter functions.
5450 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
5451 (WINDOW_INLINE): New macro.

6337 since it's used in non-static inline functions now.
6339 * xfaces.c (face_at_buffer_position, face_for_overlay_string):

6392 This how ASET and AREF are supposed to work, and makes
6393 it easier to think about future improvements. See
6394 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.

6807 * alloc.c (listn): Fix the order the arguments are consed onto the
6810 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
6811 enumeration constants, as PURE and HEAP are too general, and clash
6812 with other headers and sources, such as gmalloc.c and the
6813 MS-Windows system headers. All users changed.
6815 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
6817 Revert last save_excursion_save and save_excursion_restore changes.
6818 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

6828 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
6830 Improve GDB symbol export (Bug#12036).
6831 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
6832 arms of an 'if', not using conditional expressions; otherwise GDB
6833 complains about the types in the unevaluated arm when the argument
6834 is an integer literal.
6835 (xgetint): Simplify expression.
6836 * alloc.c (gdb_make_enums_visible): New constant. This ports to
6837 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
6838 Zaretskii in <http://bugs.gnu.org/12036#13>.
6839 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
6840 needed now that we have gdb_make_enums_visible.
6841 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
6842 (enum enum_USE_LSB_TAG):
6843 New enum types, packaging up enums that need to be exported to GDB.
6845 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
6847 Utility function to make a list from specified amount of objects.

6861 * xdisp.c (syms_of_xdisp): Likewise.
6862 * xfns.c (syms_of_xfns): Likewise.
6864 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
6866 Fast save_excursion_save and save_excursion_restore.
6867 * lisp.h (struct Lisp_Excursion): New data type.
6868 (PVEC_EXCURSION): New pseudovector type.
6869 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
6870 to deal with it. Adjust comments.
6871 (init_marker, attach_marker): New prototype.
6872 (unchain_marker): Adjust prototype.

6881 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
6883 Fix export of symbols to GDB (Bug#12036).
6884 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
6885 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
6886 emacs.c, as this is a more-suitable home. Had this been done earlier
6887 the fix for 12036 would have avoided some of the problems noted in
6888 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
6889 would have been more obvious.
6890 * emacs.c: Do not include <verify.h>; no longer needed.
6891 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
6892 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
6893 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
6894 Remove; now done in lisp.h.
6895 * lisp.h (PUBLISH_TO_GDB): New macro.
6896 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
6897 (DATA_SEG_BITS): Use it.
6898 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
6899 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
6900 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
6901 not be usable in #if. This simplifies things.
6903 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
6905 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
6907 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
6909 Simplify export of symbols to GDB (Bug#12036).
6910 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
6911 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
6912 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
6913 Adjust to changes in lisp.h and emacs.c, by using
6914 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
6915 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
6916 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
6917 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
6918 instead of gdb_valbits.
6919 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
6920 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
6921 instead of gdb_array_mark_flag.
6922 (xboolvector): Get size from $->size, not $->header.size.
6923 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
6924 (xreload, hook-run, hookpost-run): Remove.
6925 * emacs.c: Include <verify.h>.
6926 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
6927 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
6929 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
6930 (gdb_USE_LSB_TAG): New enum constants.
6931 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
6932 Also define these as enum constants, so they're visible to GDB.
6933 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
6934 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
6935 as constants, so they're visible to GDB.
6936 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
6937 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
6938 Now enum constants, not macros, so they're visible to GDB.
6939 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
6940 more convenient now. All uses changed.
6941 (VALMASK) [USE_LSB_TAG]: Also define in this case.
6942 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
6944 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

6949 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
6951 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
6952 add argument, tune behavior, and adjust all callers.
6954 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
6956 Use typedef for EMACS_INT, EMACS_UINT.
6957 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
6958 than macros. This simplifies debugging in the usual case, since
6959 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
6960 and it allows expressions involving EMACS_INT casts.
6961 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
6963 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
6965 * nsterm.m (ns_read_socket): Return early if there is a modal

6971 that FOCUS-FRAME can be omitted.
6973 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
6975 Adjust buffer text indirection counters at the end of Fkill_buffer.
6976 * buffer.c (Fkill_buffer): Adjust indirection counters when the
6977 buffer is definitely dead. This should really fix an issue reported
6978 by Christoph Scholtes again. (Bug#12007).
6979 (init_buffer_once): Initialize indirection counters of
6980 buffer_defaults and buffer_local_symbols (for sanity and safety).
6982 2012-07-24 Eli Zaretskii <eliz@gnu.org>
6984 * xdisp.c (init_iterator): Don't compute dimensions of truncation
6985 and continuation glyphs on tooltip frames, leave them at zero.

6988 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
6990 Simplify copy_overlay.
6991 * buffer.c (copy_overlay): Simplify. Use build_marker.

7000 it signals an error when a tooltip frame is being created.
7002 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
7004 Cleanup miscellaneous objects allocation and initialization.

7011 (build_overlay): Add prototype.
7013 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
7015 Swap buffer text indirection counters in Fbuffer_swap_text.
7016 * buffer.c (Fbuffer_swap_text): Swap indirections too.
7017 This avoids crash reported by Christoph Scholtes at
7018 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
7020 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
7022 * nsmenu.m (Popdown_data): New struct.
7023 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
7025 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
7026 (initWithContentRect): Make imgView and contentView non-static
7027 and autorelease them. Also autorelease img and matrix (Bug#12005).
7028 (dealloc): Remove (Bug#12005).
7030 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
7032 Adjust consing_since_gc when objects are explicitly freed.

7045 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
7047 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
7048 as it's limited by the amount of memory, not by INT_MAX.
7050 2012-07-21 Eli Zaretskii <eliz@gnu.org>
7052 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
7053 in special-event-map. See the discussion at
7054 http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00417.html
7057 * w32menu.c (add_menu_item): Cast to ULONG_PTR when assigning
7058 info.dwItemData. Fixes crashes on 64-bit Windows.

7112 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
7113 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
7114 Adjust users accordingly.
7115 * font.h (font_open_by_name): Adjust prototype.
7117 2012-07-20 Dmitry Antipov <dmantipov@yandex.ru>

7133 * buffer.h (FOR_EACH_BUFFER): Rename from 'for_each_buffer'.
7134 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
7135 'for_each_per_buffer_object_at'.
7136 All uses changed. It's better to use upper-case for macros that
7137 cannot be implemented as functions, to give the reader a clue
7138 that they're special.
7140 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>
7142 * alloc.c (Fgarbage_collect): Tweak docstring.

7183 * intervals.c (merge_interval_right, merge_interval_left):
7184 Do not zero out this interval if it is absorbed by its children,
7185 as this interval's total length doesn't change in that case. See
7186 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00403.html>.
7188 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
7190 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
7191 when invoking (make-bool-vector N t) and N is a positive
7192 multiple of 8 -- the last 8 bits were mistakenly cleared.
7194 Remove some struct layout assumptions in bool vectors.
7195 * alloc.c (bool_header_size): New constant.
7196 (header_size, word_size): Move earlier, as they're now used earlier.
7197 Use 'word_size' in a few more places, where it's appropriate.
7198 (Fmake_bool_vector, sweep_vectors): Don't assume that there is no
7199 padding before the data member of a bool vector.
7200 (sweep_vectors): Use PSEUDOVECTOR_TYPEP, in an eassert, rather
7201 than doing the check by hand with an abort ().
7203 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
7205 * eval.c (Fdefvar): Don't check constants since we only set the var if
7206 it's not yet defined anyway (bug#11904).
7208 * lisp.h (last_undo_boundary): Declare new var.
7209 * keyboard.c (command_loop_1): Set it.
7210 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
7211 were auto-added by the command loop (bug#11774).
7213 2012-07-18 Andreas Schwab <schwab@linux-m68k.org>
7215 * w32font.c (Qsymbol): Remove local definition.

7704 2012-07-11 Glenn Morris <rgm@gnu.org>
7706 * s/bsd-common.h, s/cygwin.h: No need to undefine INTERRUPT_INPUT,
7707 since nothing has defined it on these platforms.
7709 * s/aix4-2.h, s/bsd-common.h, s/cygwin.h, s/gnu-linux.h:
7710 * s/irix6-5.h: Move SIGNALS_VIA_CHARACTERS to configure.

7721 2012-07-11 John Wiegley <johnw@newartisans.com>
7723 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
7724 function attribute, so we only use it if it exists in the
7727 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
7729 Avoid call to strlen in fast_c_string_match_ignore_case.

7776 * s/aix4-2.h (unix): Remove; no longer needed.
7778 EMACS_TIME simplification (Bug#11875).
7779 This replaces macros (which typically do not work in GDB)
7780 with functions, typedefs and enums, making the code easier to debug.
7781 The functional style also makes code easier to read and maintain.
7782 * systime.h: Include <sys/time.h> on all hosts, not just if
7783 WINDOWSNT, since 'struct timeval' is needed in general.
7784 (EMACS_TIME): Now a typedef, not a macro.
7785 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
7787 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

7791 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
7792 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
7793 which are not functions. All uses rewritten to use:
7794 (make_emacs_time): New function.
7795 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
7796 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
7797 not functions. All uses rewritten to use the following, respectively:
7798 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
7799 (add_emacs_time, sub_emacs_time): New functions.
7800 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
7801 * fileio.c (Fcopy_file):
7802 * xterm.c (XTflash): Get the current time closer to when it's used.
7803 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

7811 * gtkutil.c (get_utf8_string):
7813 * nsmenu.m (ns_update_menubar):
7814 * regex.c (regerror):
7815 Prefer memcpy to strncpy and strncat when either will do.
7816 * fileio.c (Fsubstitute_in_file_name):
7817 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
7818 (menu_separator_name_p):
7819 * nsmenu.m (ns_update_menubar):
7820 Prefer memcmp to strncmp when either will do.
7821 * nsterm.m: Include <ftoastr.h>.
7823 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
7824 Prefer snprintf to strncpy.
7825 * nsterm.m (ns_term_init):
7826 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
7827 * nsterm.m (ns_term_init):
7828 Avoid the need for strncpy, by using build_string or
7829 make_unibyte_string directly. Use dtoastr, not snprintf.
7830 * process.c (Fmake_network_process): Diagnose service names that
7831 are too long, rather than silently truncating them or creating
7832 non-null-terminated names.
7833 (Fnetwork_interface_info): Likewise, for interface names.
7834 * sysdep.c (system_process_attributes) [GNU_LINUX]:
7835 Prefer sprintf to strncat.
7836 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
7837 Prefer vsnprintf to vsprintf + strncpy.
7839 2012-07-10 Glenn Morris <rgm@gnu.org>
7841 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
7842 Clarify fallback case.
7844 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
7846 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
7847 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
7848 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
7849 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
7850 where argument type is known to be a Lisp_Cons.
7852 2012-07-10 Tom Tromey <tromey@redhat.com>
7854 * bytecode.c (BYTE_CODE_THREADED): New macro.

7862 Optimize pure C strings initialization.
7863 * lisp.h (make_pure_string): Fix prototype.
7864 (build_pure_c_string): New function, defined as static inline. This
7865 provides a better opportunity to optimize away calls to strlen when
7866 the function is called with compile-time constant argument.
7867 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
7868 argument, adjust users accordingly. Use build_pure_c_string where
7870 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
7871 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
7872 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
7874 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
7876 Avoid calls to strlen in miscellaneous functions.
7877 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
7878 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
7879 * lread.c (openp): Likewise.
7881 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
7883 Avoid calls to strlen in path processing functions.
7884 * fileio.c (file_name_as_directory): Add comment. Change to add
7885 srclen argument and return the length of result. Adjust users
7887 (directory_file_name): Fix comment. Change to add srclen argument,
7888 swap 1st and 2nd arguments to obey the common convention.
7889 Adjust users accordingly.
7890 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
7892 2012-07-10 Glenn Morris <rgm@gnu.org>
7894 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:

7897 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
7898 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
7899 * s/gnu.h (DATA_START): Move definitions to configure.
7901 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
7902 We include usg5-4-common.h, which defines them both.
7904 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
7905 O_RDONLY already includes it).
7907 Stop ns builds setting the EMACSLOADPATH environment variable.
7908 * nsterm.m (ns_load_path): Rename from ns_init_paths.
7909 Now it does not set EMACSLOADPATH, just returns the load-path string.
7910 * nsterm.h: Update accordingly.
7911 * lread.c [HAVE_NS]: Include nsterm.h.
7912 (init_lread) [HAVE_NS]: Use ns_load_path.
7913 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
7915 2012-07-09 Glenn Morris <rgm@gnu.org>
7917 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
7918 since the included bsd-common.h does so.
7920 Stop ns builds setting the EMACSPATH environment variable.
7921 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
7922 (ns_init_paths): Do not set EMACSPATH.
7923 * nsterm.h (ns_exec_path): Add it.
7924 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
7927 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
7929 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
7931 * process.c (wait_reading_process_output): 'waitchannels' was unset
7932 when read_kbd || !NILP (wait_for_cell); fix this.
7934 Add GCC-style 'const' attribute to functions that can use it.
7935 * character.h (char_resolve_modifier_mask):
7936 * keyboard.h (make_ctrl_char):
7937 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
7938 (init_character_once, next_almost_prime, init_fns, init_image)
7939 (flush_pending_output, init_sound):
7940 * mem-limits.h (start_of_data):

7944 Declare the dummy function with ATTRIBUTE_CONST.
7945 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
7946 Add decls with ATTRIBUTE_CONST.
7948 Minor improvements to make_formatted_string.
7949 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
7950 where int is good enough, as vsprintf returns an int.
7951 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
7953 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7955 Use make_formatted_string to avoid double length calculation.
7956 * lisp.h (make_formatted_string): New prototype.
7957 * alloc.c (make_formatted_string): New function.
7958 * buffer.c (Fgenerate_new_buffer_name): Use it.
7959 * dbusbind.c (syms_of_dbusbind): Likewise.
7960 * editfns.c (Fcurrent_time_zone): Likewise.
7961 * filelock.c (get_boot_time): Likewise.
7962 * frame.c (make_terminal_frame, set_term_frame_name)
7963 (x_report_frame_params): Likewise.
7964 * image.c (gs_load): Likewise.
7965 * minibuf.c (get_minibuffer): Likewise.

7980 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7982 Move marker debugging code under MARKER_DEBUG.
7983 * marker.c (MARKER_DEBUG): Move marker debugging code under
7984 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
7985 for bootstrap with --enable-checking (~3x slowdown reported
7986 by Juanma Barranquero <lekktu@gmail.com>).
7987 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
7989 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
7991 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
7992 See <http://bugs.gnu.org/11825#29>.
7994 2012-07-08 Eli Zaretskii <eliz@gnu.org>
7996 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
7997 has no font, use the frame's font. (Bug#11813)
7998 (display_line): Add commentary about displaying truncation glyphs
8000 (produce_special_glyphs): Move here from term.c.
8002 * term.c (produce_special_glyphs): Move to xdisp.c.
8004 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
8007 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
8009 * xdisp.c (display_line): Avoid warning about implicit declaration
8012 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
8014 * lisp.h: Remove empty conditional.
8016 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8018 * lread.c (load_path_check): Now static.
8020 Fix some minor --with-ns problems found by static checking.
8021 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
8022 (x_set_font) [!HAVE_X_WINDOWS]:
8023 * image.c (xpm_load_image) [HAVE_NS]:
8024 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
8025 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
8026 Remove unused local.
8027 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
8028 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
8029 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
8030 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
8031 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
8032 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
8033 Fix pointer signedness problem.
8034 * xfaces.c (FRAME_X_FONT_TABLE):
8035 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
8037 2012-07-07 Glenn Morris <rgm@gnu.org>
8039 * lread.c (load_path_check): New function, split from init_lread.
8040 (init_lread): Reorganize. Motivation:
8041 If EMACSLOADPATH is set, check/warn about that rather than the
8042 defaults, which we are not going to use. Hence we can remove
8043 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
8044 Don't warn if site-lisp directories are missing.
8045 If not installed, start from a blank load-path, since
8046 PATH_LOADSEARCH refers to the eventual installation directories.
8048 2012-07-07 Eli Zaretskii <eliz@gnu.org>
8050 Support truncation and continuation glyphs on GUI frames, when
8051 fringes are disabled. (Bug#11832)
8052 * xdisp.c (init_iterator): Get dimensions of truncation and
8053 continuation glyphs even if on GUI frames.
8054 Adjust it->last_visible_x on GUI frames when the left or right fringes,
8055 or both, are absent.
8056 (start_display, move_it_in_display_line_to): Handle the case of a
8057 GUI frame without a fringe to display continuation or truncation
8059 (insert_left_trunc_glyphs): Support GUI frames: make sure
8060 truncation glyphs overwrite enough glyphs from the current line to
8061 have sufficient space in pixels.
8062 (display_line): Support truncation and continuation glyphs on GUI
8063 frames. If some spare pixels are left on the line after inserting
8064 the truncation glyphs, fill that space with a stretch glyph of a
8065 suitably computed width.
8067 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
8068 produce_glyphs, to support GUI sessions.
8070 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8072 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
8074 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
8076 Do not require float-time's arg to fit in time_t (Bug#11825).
8077 This works better on hosts where time_t is unsigned, and where
8078 float-time is applied to the (negative) difference between two times.
8079 * editfns.c (decode_time_components): Last arg is now double *,
8080 not int *, and means to store all the result as a double, without
8081 worrying about whether the seconds part fits in time_t.
8082 All callers changed.
8083 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
8084 All callers changed.
8085 (Ffloat_time): Do not fail merely because the specified time falls
8086 outside of time_t range.
8088 2012-07-07 Glenn Morris <rgm@gnu.org>
8090 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

8094 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
8096 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
8097 Update dependencies.
8099 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
8101 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8103 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
8104 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
8105 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
8106 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
8107 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
8108 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
8110 * xfont.c (compare_font_names): Redo to omit the need for casts.
8112 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
8114 * xfns.c (Fx_change_window_property): Doc fix.
8115 * w32fns.c (Fx_change_window_property): Doc fix.
8117 * w32fns.c (Fx_window_property): Accept the same arguments as the
8118 X Windows version. Doc fix.
8119 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
8121 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
8122 Eli Zaretskii <eliz@gnu.org>
8124 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
8125 Windows-specific code from nt/config.nt moved here.
8126 Obsolete settings removed.
8128 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8130 * process.c: Avoid unnecessary calls to gettime.
8131 (wait_reading_process_output): Don't get the time of day
8132 when gobbling data immediately and not waiting, as there's no need
8133 for it in that case. This removes a FIXME.
8135 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
8137 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
8138 is defined (Bug#11768).
8140 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8142 Fix marker debugging code.
8143 * marker.c (byte_char_debug_check): Do not perform the check
8144 if buffer is not multibyte.
8145 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8146 Call byte_char_debug_check with correct arguments.
8148 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8150 Compile marker debugging code only if ENABLE_CHECKING is defined.
8151 * marker.c (byte_char_debug_check, count_markers):
8152 Use only if ENABLE_CHECKING is defined.
8153 (byte_debug_flag): Remove.
8154 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8155 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
8157 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8159 Avoid code repetition in marker-related functions.
8160 * marker.c (attach_marker): New function.

8162 (set_marker_restricted_both): Use it.
8163 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
8164 Consistently rename charno to charpos.
8165 (marker_position): Add eassert.
8166 (marker_byte_position): Convert to eassert.
8168 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

8178 * lisp.h (build_marker): New prototype.
8179 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
8180 * composite.c (autocmp_chars): Likewise.
8181 * editfns.c (buildmark): Remove.
8182 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
8183 (save_restriction_save): Use build_marker.
8184 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
8185 * window.c (save_window_save): Likewise.
8187 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

8190 to avoid redundant calls to unchain_overlay.
8191 * buffer.c (drop_overlay): New function.
8192 (delete_all_overlays, Fdelete_overlay): Use it.
8193 * minibuf.c (get_minibuffer): Fix comment.
8195 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8197 Port to OpenBSD 5.1 amd64.
8198 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
8199 This is needed for OpenBSD, and should be harmless on all BSD systems.
8200 Also, include <sys/sysctl.h>, as it should be available on all
8201 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
8202 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
8203 use p_pid member, not kp_proc.pid.
8205 2012-07-06 Glenn Morris <rgm@gnu.org>
8207 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
8209 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
8211 More xmalloc and related cleanup.
8212 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

8220 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
8222 Omit needless casts involving void * pointers and allocation.
8223 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
8224 as the former is more robust if P's type is changed.
8225 Prefer xzalloc to xmalloc + memset 0.
8226 Simplify malloc-or-realloc to realloc.
8227 Don't worry about xmalloc returning a null pointer.
8228 Prefer xstrdup to xmalloc + strcpy.
8229 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
8231 * keyboard.c (apply_modifiers_uncached): Prefer local array to
8232 alloca of a constant.
8234 2012-07-05 Eli Zaretskii <eliz@gnu.org>
8236 * xdisp.c (display_line): Fix horizontal pixel coordinates when
8237 hscroll is larger than the line width. Fixes long and futile
8238 looping inside extend_face_to_end_of_line (on a TTY) producing
8239 glyphs that are not needed and thrown away.
8241 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
8243 * marker.c (set_marker_restricted_both): Simplify by using
8246 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
8248 * editfns.c (region_limit): Simplify by using clip_to_bounds.

8253 not defined (Bug#11768).
8254 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
8255 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
8256 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
8257 followed by gtk_box_set_homogeneous (Bug#11768).
8258 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
8259 (update_theme_scrollbar_width, xg_create_scroll_bar):
8260 Use gtk_scrollbar_new (Bug#11768).
8261 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
8262 (is_box_type): New function (Bug#11768).
8263 (xg_tool_item_stale_p): Call is_box_type.
8264 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
8265 with default display (Bug#11768).

8269 * xdisp.c (window_hscroll_limited): New function.
8270 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
8271 coordinates when window's hscroll is set to insanely large
8274 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
8276 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

8337 * fileio.c (time_error_value): Check the right error number.
8338 Problem reported by Troels Nielsen in
8339 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
8341 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8343 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
8344 This should be fixed in a better way; see Eli Zaretskii in
8345 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
8346 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
8348 * fileio.c (time_error_value): Rename from special_mtime.
8349 The old name's problems were noted by Eli Zaretskii in
8350 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
8352 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
8353 This variable's comment says Emacs needs at least one GDB-visible
8354 symbol of type enum pvec_type, to work around GDB problems.
8355 The symbol's value doesn't matter.
8357 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
8358 that causes compilation to fail on pre-C99 compilers.
8360 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
8362 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
8363 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
8365 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8367 * buffer.c (init_buffer_once): Fix initialization of
8368 headers for buffer_defaults and buffer_local_symbols.
8369 Reported by Juanma Barranquero <lekktu@gmail.com>.
8371 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
8373 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
8374 * lisp.h (enum pvec_type): Use fewer bits.
8375 (PSEUDOVECTOR_SIZE_BITS): New constant.
8376 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
8377 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
8378 change in pvec_type.
8379 (PSEUDOVECTOR_TYPEP): New macro.

8385 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
8386 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
8387 (sweep_vectors): Use it. Use local var `total_bytes' instead of
8388 abusing vector->header.next.nbytes.
8389 (live_vector_p): Use PVEC_TYPE.
8390 (mark_object): Adapt code to extract pvectype. Use switch.
8392 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8394 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
8395 Tighten new eassert a bit.
8397 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8399 Fix compilation with --enable-gcc-warnings and -O1
8401 * doprnt.c (doprnt): Change type of tem to int, initialize
8402 to avoid compiler warning. Add eassert.
8403 * search.c (simple_search): Initialize match_byte to avoid
8404 compiler warning. Add eassert.
8406 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8408 Avoid weird behavior with large horizontal scrolls.
8409 Without this change, for example, large hscroll values would
8410 mess up Emacs's display on Fedora 15 x86, presumably due to
8411 overflows in int calculations in the display code.
8412 Also, if buffers had long lines, Emacs would freeze.
8413 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
8414 (set_window_hscroll): New function, containing the old guts of
8415 Fset_window_hscroll. Return the clipped value.
8416 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
8417 This avoids the need to check against PTRDIFF_MAX.
8419 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
8421 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8423 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
8425 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8427 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
8428 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
8429 since GCC 4.4.6 issues a bogus warning for them.
8431 Fix bugs in file timestamp newness comparisons.
8432 * fileio.c (Ffile_newer_than_file_p):
8433 * lread.c (Fload): Use full timestamp resolution of files,
8434 not just the 1-second resolution, so that files that are only
8435 slightly newer still count as newer.
8436 * fileio.c (Ffile_newer_than_file_p): Don't assume file
8437 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
8439 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
8441 * fileio.c: Improve handling of file time marker. (Bug#11852)
8442 (special_mtime): New function.
8443 (Finsert_file_contents, Fverify_visited_file_modtime):
8444 Use it to set special mtime values consistently.
8446 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
8448 * fileio.c (Finsert_file_contents): Properly handle st_mtime
8449 marker for non-existing file. (Bug#11852)
8451 2012-07-03 Glenn Morris <rgm@gnu.org>
8453 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
8454 and did not make it into globals.h).
8456 2012-07-03 Tom Tromey <tromey@redhat.com>

8494 2012-07-03 Glenn Morris <rgm@gnu.org>
8496 * lisp.h (Frandom): Make it visible to C.
8497 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
8498 buffer for invisible buffers. (Bug#1229)

8502 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
8503 values which aren't power of 2.
8504 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
8505 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
8508 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
8510 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.

8516 * alloc.c (allocate_vector_block): Remove redundant
8517 calls to mallopt if DOUG_LEA_MALLOC is defined.
8518 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
8519 avoid calls to mallopt if zero_vector is returned.
8521 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8523 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
8524 is enabled, avoid dereferencing NULL current_sblock if
8527 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8529 Cleanup basic buffer management.
8530 * buffer.h (struct buffer): Change layout to use generic vector
8531 marking code. Fix some comments. Change type of 'clip_changed'
8532 to bitfield. Remove unused #ifndef old.
8533 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
8534 (GET_OVERLAYS_AT): Fix indentation.

8539 * alloc.c (allocate_buffer): Adjust to match new layout of
8540 struct buffer. Fix comment.
8541 (mark_overlay): New function.

8543 Lisp area of struct buffer.
8544 (mark_object): Use it. Adjust marking of misc objects
8545 and related comments.
8547 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
8549 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
8550 wrapper that is not needed because the wrapped code is a no-op (zero
8551 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
8552 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
8554 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
8556 * alloc.c (mark_buffer): Simplify. Remove prototype.
8557 (mark_object): Add comment. Reorganize marking of vector-like
8558 objects. Use CHECK_LIVE for all vector-like objects except buffers
8559 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
8560 Avoid redundant calls to mark_vectorlike for bool vectors.
8562 2012-06-30 Glenn Morris <rgm@gnu.org>
8564 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
8566 * epaths.in (PATH_SITELOADSEARCH): New.
8567 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
8568 This is rather than relying on --enable-locallisppath elements
8569 having "site-lisp" in their names. (Bug#10208#25, 11658)
8571 2012-06-30 Eli Zaretskii <eliz@gnu.org>
8573 * w32proc.c (sys_select): Accept and ignore one more argument.

8582 * process.c (sys_select):
8583 * msdos.c (sys_select): Accept one more argument and ignore it.
8585 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
8586 adapt data types and code to that.
8589 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
8590 which clashes with the gnulib function of the same name.
8592 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
8594 * font.c (font_style_to_value, font_style_symbolic)
8595 (font_prop_validate_style): Add type checks for values in
8598 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
8600 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
8603 2012-06-29 Eli Zaretskii <eliz@gnu.org>
8605 * xdisp.c (try_window_id): Undo last change.
8607 * w32.c (getwd): Adjust commentary about startup_dir.
8608 (init_environment): Always call sys_access, even in non-MSVC
8609 builds. Don't chdir to the directory of the Emacs executable.
8610 This undoes code from 1997 which was justified by the need to
8611 "avoid conflicts when removing and renaming directories". But its
8612 downside was that every relative file name was being interpreted
8613 relative to the directory of the Emacs executable, which can never
8614 be TRT. In particular, it broke sys_access when called with
8615 relative file names.
8616 (sys_access): Map GetLastError to errno.
8618 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8620 * window.h (struct window): Change type of 'fringes_outside_margins'

8665 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
8666 from EMACS_INT to ptrdiff_t.

8808 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
8810 Use sprintf return value instead of invoking strlen on result.
8811 In the old days this wasn't portable, since some sprintf
8812 implementations returned char *. But they died out years ago and
8813 Emacs already assumes sprintf returns int.
8814 Similarly for float_to_string.
8815 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

8822 * xfns.c (syms_of_xfns):
8823 Use sprintf or float_to_string result to avoid need to call strlen.
8824 * data.c (Fnumber_to_string):
8825 Use make_unibyte_string, since the string must be ASCII.
8826 * lisp.h, print.c (float_to_string): Now returns int length.
8827 * term.c (produce_glyphless_glyph):
8828 Use sprintf result rather than recomputing it.
8830 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
8831 * Makefile.in (ALL_CFLAGS):
8832 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

8838 strcasecmp if available.

8861 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
8863 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

8866 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
8868 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
8869 instead of truncating it to 63 (admittedly a generous limit).
8871 * process.c: Fix spelling and caps in comments.

8929 * keyboard.c (kbd_buffer_get_event):
8930 * process.c (Faccept_process_output):
8931 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
8932 This improves on the previous patch, which introduced a bug

8999 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
9001 Support higher-resolution time stamps (Bug#9000).
9002 The time stamps are only nanosecond-resolution at the C level,
9003 since that's the best that any real-world system supports now.
9004 But they are picosecond-resolution at the Lisp level, as that's
9005 easy, and leaves room for future OS improvements.
9007 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
9010 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
9011 Don't get current time unless it's needed.
9013 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
9014 now provides it if it's absent.
9015 (start_atimer): Port to higher-res time stamps.
9016 Check for time stamp overflow. Don't get current time more
9017 often than is needed.
9019 * buffer.h (struct buffer): Buffer modtime now has high resolution.
9020 Include systime.h, not time.h.
9021 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
9023 * dired.c: Include stat-time.h.
9024 (Ffile-attributes): File times now have higher resolution.
9026 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
9027 (struct image): Timestamp now has higher resolution.
9029 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
9030 has at least microseconds now. All uses removed.
9031 (update_frame, update_single_window, update_window, update_frame_1)
9032 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
9033 (duration_to_sec_usec): Remove; no longer needed.
9035 * editfns.c (time_overflow): Now extern.
9036 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
9037 (float-time, Fformat_time_string, Fcurrent_time_string)
9038 (Fcurrent_time_zone): Accept and generate higher-resolution
9040 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
9041 (decode_time_components, lisp_seconds_argument): New functions.
9042 (make_time): Now static.
9043 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
9044 Report an error if the time is invalid, rather than having the caller
9047 * fileio.c: Include <stat-time.h>
9048 (Fcopy_file): Copy higher-resolution time stamps.
9049 Prefer to set the time stamp via a file descriptor if that works.
9050 (Fset_file_times, Finsert_file_contents, Fwrite_region)
9051 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
9052 (Fvisited_file_modtime, Fset_visited_file_modtime):
9053 Support higher-resolution time stamps.
9055 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
9057 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
9059 * image.c (prepare_image_for_display, clear_image_cache)
9060 (lookup_image): Port to higer-resolution time stamps.
9062 * keyboard.c (start_polling, bind_polling_period):
9063 Check for time stamp overflow.
9064 (read_char, kbd_buffer_get_event, timer_start_idle)
9065 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
9066 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
9067 Port to higher-resolution time stamps. Do not assume time_t is signed.
9068 (decode_timer): New function. Timers are now vectors of length 9,
9069 not 8, to accommodate the picosecond component.
9070 (timer_check_2): Use it.
9072 * nsterm.m (select_timeout, timeval_subtract): Remove.
9073 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
9074 as they're a bit more accurate and handle overflow better.
9075 (ns_select): Change prototype to be compatible with pselect.
9076 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
9077 * nsterm.h (ns_select): Adjust prototype.
9079 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
9080 us-resolution time stamps.
9081 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
9083 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
9085 * lisp.h (time_overflow): New decl.
9086 (wait_reading_process_output): First arg is now intmax_t, not int,
9087 to accommodate larger waits.
9089 * process.h (struct Lisp_Process.read_output_delay):
9090 Now counts nanoseconds, not microseconds.
9091 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about

9094 (wait_reading_process_output):
9095 Port to ns-resolution time stamps.
9096 (Faccept_process_output, wait_reading_process_output):
9097 Check for time stamp overflow. Do not assume time_t is signed.
9098 (select_wrapper): Remove; we now use pselect.
9099 (Fprocess_attributes): Now generates ns-resolution time stamps.
9101 * sysdep.c: Include utimens.h. Don't include utime.h
9102 or worry about struct utimbuf; gnulib does that for us now.

9104 (make_timeval): New function.
9105 (set_file_times): Now sets ns-resolution time stamps.
9106 New arg FD; all uses changed.
9107 (time_from_jiffies, ltime_from_jiffies, get_up_time)

9109 Now returns ns-resolution time stamp. All uses changed.
9110 Check for time stamp overflow.
9112 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
9113 provides a substitute now.
9115 * systime.h: Include timespec.h rather than sys/time.h and time.h,
9116 since it guarantees struct timespec.
9117 (EMACS_TIME): Now struct timespec, so that we can support
9118 ns-resolution time stamps.
9119 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.

9121 (EMACS_USECS): Remove.
9122 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
9123 so multiply the arg by 1000 before storing it.

9133 (make_timeval, make_lisp_time, decode_time_components): New decls.
9134 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
9135 that it mishandled time_t overflow. You can't compare by subtracting!
9136 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
9137 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.

9148 (w32_get_internal_run_time):
9149 Port to higher-resolution Emacs time stamps.

9155 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
9156 for compatibility with pselect. Support ns-resolution time stamps.

9160 * xselect.c (wait_for_property_change, x_get_foreign_selection):
9161 Check for time stamp overflow, and support ns-resolution time stamps.

9164 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
9165 (timeval_subtract): Remove; no longer needed.
9166 (XTflash, XTring_bell, x_wait_for_event):
9167 Port to ns-resolution time stamps. Don't assume time_t is signed.

9173 2012-06-22 Eli Zaretskii <eliz@gnu.org>
9175 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
9176 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
9177 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
9178 staticidx goes up to 1597 out of 1600 = 0x640.)

9182 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
9183 Otherwise, the umask might be mistakenly 0 while handling input signals.

9197 2012-06-19 Chong Yidong <cyd@gnu.org>
9199 * frame.c (delete_frame): When selecting a frame on a different

9204 (unwind_format_mode_line): Restore them.
9205 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
9207 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
9208 since tty frames can be explicitly named.
9209 (prepare_menu_bars): Likewise.
9211 * term.c (Ftty_top_frame): New function.
9213 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

9216 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
9217 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
9218 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
9219 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

9228 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
9229 gets killed during executing of this function (Bug#11665).
9230 Try to always return Qt when the buffer has been actually killed.
9231 (Vkill_buffer_query_functions): In doc-string say that functions
9232 run by this hook should not change the current buffer.
9234 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
9236 Fix recently-introduced process.c problems found by static checking.
9237 * process.c (write_queue_push, write_queue_pop, send_process):

9257 This removes the need for CHECK.
9258 (CHECK): Remove. Its comments about always evaluating its
9259 argument were confusing, as 'eassert' typically does not evaluate
9262 * coding.c (produce_chars): Use ptrdiff_t, not int.
9264 * xterm.c (x_draw_underwave): Check for integer overflow.
9265 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

9558 2012-06-08 Juanma Barranquero <lekktu@gmail.com>
9560 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
9561 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
9563 2012-06-08 Eli Zaretskii <eliz@gnu.org>
9565 * alloc.c (allocate_vectorlike): Fix last change.
9567 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
9569 Block-based vector allocation of small vectors.
9570 * lisp.h (struct vectorlike_header): New field `nbytes',
9571 adjust comment accordingly.
9572 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
9573 to denote vector blocks. Adjust users (live_vector_p,
9574 mark_maybe_pointer, valid_lisp_object_p) accordingly.
9575 (COMMON_MULTIPLE): Move outside #if USE_LSB_TAG.
9576 (VECTOR_BLOCK_SIZE, vroundup, VECTOR_BLOCK_BYTES),
9577 (VBLOCK_BYTES_MIN, VBLOCK_BYTES_MAX, VECTOR_MAX_FREE_LIST_INDEX),
9578 (VECTOR_FREE_LIST_FLAG, ADVANCE, VINDEX, SETUP_ON_FREE_LIST),
9579 (VECTOR_SIZE, VECTOR_IN_BLOCK): New macros.
9580 (roundup_size): New constant.

9594 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
9596 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
9598 * doprnt.c (doprnt): Truncate multibyte char correctly.
9599 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
9600 would mishandle a string argument "Xc" if X was a multibyte
9601 character of length 2: it would truncate after X's first byte
9602 rather than including all of X.
9604 2012-06-06 Chong Yidong <cyd@gnu.org>
9606 * buffer.c (word_wrap): Doc fix.
9608 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

9629 2012-06-03 Chong Yidong <cyd@gnu.org>
9631 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
9632 (note_mode_line_or_margin_highlight): If there is no help echo,
9633 use mode-line-default-help-echo. Handle the case where the mouse
9634 position is past the end of the mode line string.
9636 * buffer.c (buffer_local_value_1): New function, split from
9637 Fbuffer_local_value; can return Qunbound.

9648 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
9649 and DEFVAR it. Update all users.

9653 * minibuf.c (Fassoc_string): Remove duplicate declaration.
9655 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
9656 Convert pctcpu and pctmem to Lisp float properly.
9657 Let the compiler fold better, as 100.0/0x8000 is exact.
9659 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
9661 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
9664 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
9666 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
9668 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
9670 For a 'struct window', replace some Lisp_Object fields to
9671 bitfields where appropriate, remove unused fields.
9672 * window.h (struct window): Remove unused 'last_mark_x' and
9673 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
9674 change its type from Lisp_Object to bitfield.
9675 Change type of 'force_start', 'optional_new_start',
9676 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
9677 fields from Lisp_Object to bitfield. Adjust users accordingly.
9679 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
9681 Pacify gcc -Wdouble-precision when using Xaw.
9682 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
9683 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
9684 Use 'float' consistently, rather than 'float' in most places
9685 and 'double' in a couple of places.
9687 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9689 * xdisp.c (handle_stop): Detect whether we have overlay strings
9690 loaded by testing it->current.overlay_string_index to be
9691 non-negative, instead of checking whether n_overlay_strings is
9692 positive. (Bug#11587)
9694 2012-05-31 Chong Yidong <cyd@gnu.org>
9696 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
9698 * doc.c (Fsubstitute_command_keys): Doc fix.
9700 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9702 * search.c (search_buffer): Remove calls to
9703 r_alloc_inhibit_buffer_relocation, as it is now called by
9704 maybe_unify_char, which was the cause of relocation of buffer text
9707 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9709 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
9710 for the duration of call to load_charset, to avoid problems with
9711 callers of maybe_unify_char that access buffer text through C
9714 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
9715 decrement the inhibition flag, instead of just setting or
9718 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
9720 Remove obsolete '#define static' cruft.
9721 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
9722 This #undef was "temporary" in 2000; it is no longer needed
9723 now that '#define static' has gone away.
9724 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
9725 (gray_bitmap_bits): Remove; no longer needed.
9726 All uses replaced with definiens.
9727 * xterm.c: Include "bitmaps/gray.xbm".
9729 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
9731 Clean up __executable_start, monstartup when --enable-profiling.
9732 The following changes affect the code only when profiling.
9733 * dispnew.c (__executable_start): Rename from safe_bcopy.
9734 Define only on platforms that need it.
9735 * emacs.c: Include <sys/gmon.h> when profiling.
9736 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
9737 (__executable_start): Remove decl, since lisp.h does it now.
9738 (safe_bcopy): Remove decl; no longer has that name.
9739 (main): Coalesce #if into single bit of code, for simplicity.
9740 Cast pointers to uintptr_t, since standard libraries want integers

9744 2012-05-31 Glenn Morris <rgm@gnu.org>
9746 * image.c (Fimagemagick_types): Doc fix.

9765 * lread.c (read1): Tiny simplification.
9767 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
9769 Do not create empty overlays with the evaporate property (Bug#9642).
9770 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
9771 Bug#9642, but explicitly check that the buffer the overlay would
9772 be moved to is live and rearrange lines to make sure that errors
9773 will not put the overlay in an inconsistent state.
9774 (Fdelete_overlay): Cosmetics.
9776 2012-05-28 Eli Zaretskii <eliz@gnu.org>
9778 * w32term.c (my_bring_window_to_top): New function.
9779 (x_raise_frame): Use handle returned by DeferWindowPos, which
9780 could be different from the original one.
9781 Call my_bring_window_to_top instead of my_set_foreground_window.
9784 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
9785 by calling BringWindowToTop.
9787 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
9788 (WM_EMACS_END): Increase by one.
9790 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
9792 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
9793 This avoids undefined behavior that might cause the eassert
9794 to not catch an out-of-range value.
9796 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
9798 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

9808 when referring to sectname field in printf format.
9810 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
9812 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
9813 Only r_alloc_inhibit_buffer_relocation needed to be added;
9814 the others were already declared.
9816 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
9817 before checking whether it's out of range. Put the check inside
9819 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
9821 2012-05-27 Ken Brown <kbrown@cornell.edu>
9823 * callproc.c (Fcall_process): Restore a line that was accidentally
9824 commented out in the 2011-02-13 change (bug#11547).
9826 2012-05-27 Eli Zaretskii <eliz@gnu.org>
9828 * lisp.h [REL_ALLOC]: Add prototypes for external functions
9829 defined on ralloc.c.
9831 * buffer.c [REL_ALLOC]: Remove prototypes of
9832 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
9833 they are now on lisp.h.
9835 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
9837 * search.c (search_buffer): Use it to inhibit relocation of buffer
9838 text while re_search_2 is doing its job, because re_search_2 is
9839 passed C pointers to buffer text. (Bug#11519)
9841 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
9844 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
9845 state after an additional call to move_it_in_display_line_to, keep
9846 the values of it->max_ascent and it->max_descent found for the
9848 (pos_visible_p): Revert the comparison against bottom_y to what it
9849 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
9852 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
9854 Fix coding-related core dumps with gcc -ftrapv.
9855 The code was computing A - B, where A and B are pointers, and B is
9856 random garbage. This can lead to core dumps on platforms that
9857 have special pointer registers, and it also leads to core dumps on
9858 x86-64 when compiled with gcc -ftrapv. The fix is to compute
9859 A - B only when B is initialized properly.
9860 * coding.c (coding_set_source, coding_set_destination): Return void.
9861 (coding_change_source, coding_change_destinations): New functions,
9862 with the old behaviors of coding_set_source and coding_set_destination.
9863 All callers that need an offset changed to use these new functions.
9865 2012-05-26 Glenn Morris <rgm@gnu.org>
9867 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
9869 2012-05-26 Eli Zaretskii <eliz@gnu.org>
9871 Extend mouse support on W32 text-mode console.
9872 * xdisp.c (draw_row_with_mouse_face):
9873 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
9875 * w32console.c: Include window.h.
9876 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
9878 (initialize_w32_display): Initialize mouse-highlight data.
9880 * w32inevt.c: Include termchar.h and window.h.
9881 (do_mouse_event): Support mouse-autoselect-window. When the mouse
9882 moves, call note_mouse_highlight. If help_echo changed, call
9883 gen_help_event to produce help-echo message in the echo area.
9884 Call clear_mouse_face if mouse_face_hidden is set in the mouse
9887 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
9889 * lread.c (read1): Simplify slightly to avoid an overflow warning
9890 with GCC 4.7.0 on x86-64.
9892 2012-05-26 Eli Zaretskii <eliz@gnu.org>
9894 * bidi.c (bidi_mirror_char): Revert last change: an int is
9895 definitely wide enough here.
9897 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
9899 Fix integer width and related bugs (Bug#9874).

9907 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
9909 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9910 (allocate_pseudovector):
9911 Use int, not EMACS_INT, where int is wide enough.
9912 (inhibit_garbage_collection, Fgarbage_collect):
9913 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9914 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
9915 int might not be wide enough.
9916 (bidi_cache_search, bidi_cache_find, bidi_init_it)

9919 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
9920 (bidi_level_of_next_char, bidi_move_to_visually_next):
9921 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9922 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)

9924 (advance_to_char_boundary, Fbuffer_swap_text)
9925 (Fset_buffer_multibyte, overlays_at, overlays_in)
9926 (overlay_touches_p, struct sortvec, record_overlay_string)
9927 (overlay_strings, recenter_overlay_lists)
9928 (adjust_overlays_for_insert, adjust_overlays_for_delete)
9929 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
9930 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
9931 (Foverlay_recenter, last_overlay_modification_hooks_used)
9932 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
9933 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9934 (validate_region): Omit unnecessary test for b <= e,
9935 since that's guaranteed by the previous test.
9936 (adjust_overlays_for_delete): Avoid pos + length overflow.
9937 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
9938 (report_overlay_modification):
9939 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9940 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
9941 Omit pointer cast, which isn't needed anyway, and doesn't work
9942 after the EMACS_INT -> ptrdiff_t change.
9943 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
9944 * buffer.h: Adjust decls to match defn changes elsewhere.
9945 (struct buffer_text, struct buffer):
9946 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9947 Use EMACS_INT, not int, where int might not be wide enough.
9948 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
9949 not int, to avoid needless 32-bit limit on 64-bit hosts.
9950 (exec_byte_code): Use tighter memory-full test, one that checks
9951 for alloca overflow. Don't compute the address of the object just
9952 before an array, as that's not portable. Use EMACS_INT, not
9953 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
9954 * callint.c (Fcall_interactively):
9955 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9956 * callproc.c (call_process_kill, Fcall_process):
9957 Don't assume pid_t fits into an Emacs fixnum.

9966 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
9967 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9968 (casify_object): Avoid integer overflow when overallocating buffer.
9969 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
9970 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
9971 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
9972 * category.h (CATEGORYP): Don't assume arg is nonnegative.
9973 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
9974 integers are now checked earlier. All uses replaced with XINT.
9976 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9977 For CCL_MapSingle, check that content and value are in int range.

9979 Check that Vcode_version_map_vector is a vector.
9980 (resolve_symbol_ccl_program): Check that vector header is in range.
9981 Always copy the vector, so that we can check its contents reliably
9982 now rather than having to recheck each instruction as it's being
9983 executed. Check that vector words fit in 'int'.
9984 (ccl_get_compiled_code, Fregister_ccl_program)
9985 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
9986 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
9987 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
9988 contents are in range.
9989 (Fccl_execute_on_string): Check that status is in range.
9990 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
9991 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
9992 Accept and return EMACS_INT, not int, because callers can pass values
9994 (c_string_width, strwidth, lisp_string_width, chars_in_text)

9999 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10000 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
10001 avoid mishandling large integers.

10013 Don't assume unsigned int fits into fixnum, or that fixnum fits

10668 (Fx_create_frame, x_create_tip_frame, Fx_show_tip)
10669 (Fx_hide_tip, Fx_file_dialog, Fx_select_font):
10670 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10671 (Fx_change_window_property): Don't assume fixnums fit in int.
10672 * xfont.c (xfont_chars_supported):
10673 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10674 * xmenu.c (Fx_popup_dialog, set_frame_menubar)
10675 (create_and_show_popup_menu, create_and_show_dialog, xmenu_show):
10676 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10677 * xml.c (parse_region):
10678 * xrdb.c (magic_file_p):
10679 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10680 * xselect.c (TRACE1): Don't assume pid_t promotes to int.
10681 (x_get_local_selection, x_reply_selection_request)
10682 (x_handle_selection_request, wait_for_property_change):
10683 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10684 (selection_data_to_lisp_data): Use short, not EMACS_INT, where
10685 short is wide enough.
10686 (x_send_client_event): Don't assume fixnum fits in int.
10687 * xterm.c (x_x_to_emacs_modifiers):
10688 Don't assume EMACS_INT overflows nicely into int.
10689 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
10690 may come from Lisp.
10691 (handle_one_xevent): NATNUMP can eval its arg twice.
10692 (x_connection_closed):
10693 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10694 * xterm.h: Adjust decls to match defn changes elsewhere.
10695 (struct scroll_bar): Use struct vectorlike_header
10696 rather than rolling our own approximation.
10697 (SCROLL_BAR_VEC_SIZE): Remove; not used.
10699 2012-05-25 Glenn Morris <rgm@gnu.org>
10701 * lisp.mk (lisp): Update for more files being compiled now.
10703 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
10705 * lread.c: Remove `read_pure' which makes no difference.
10706 (read_pure): Remove var.
10707 (unreadpure): Remove function.
10708 (readevalloop): Don't call read_list with -1 flag.
10709 (read1, read_vector): Don't test read_pure any more.
10710 (read_list): Simplify.
10712 * fileio.c, character.h: Minor style tweaks.
10714 2012-05-24 Dmitry Antipov <dmantipov@yandex.ru>
10716 * window.h (clip_changed): Remove useless declaration.
10718 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
10720 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
10721 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
10723 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
10726 This directory predates autoconf and is no longer needed nowadays.
10727 Move its few remaining bits of functionality to where they're needed.
10728 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
10729 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
10730 * m/template.h: Remove.
10731 * Makefile.in (M_FILE): Remove. All uses removed.
10732 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
10733 * lisp.h (USE_LSB_TAG):
10734 * mem-limits.h (EXCEEDS_LISP_PTR):
10735 Use VAL_MAX, not VALBITS, in #if.
10736 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
10737 (EMACS_UINT): Define unconditionally now.
10738 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
10739 (BITS_PER_EMACS_INT): New constants, replacing
10740 what used to be in config.h, but not useful in #if.
10741 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
10742 define them any more.
10743 (VAL_MAX): New macro.
10745 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
10746 BITS_PER_EMACS_INT, in #if.
10747 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
10748 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
10749 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
10750 * s/ms-w32.h (DATA_START):
10751 Move here from removed file m/intel386.h.
10752 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
10753 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
10755 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
10757 Assume C89 or later.
10758 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
10759 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
10761 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
10762 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
10763 * textprop.c, tparam.c (NULL): Remove.
10764 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
10765 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
10766 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
10767 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
10768 * xterm.c (input_signal_count): Assume volatile works.
10770 2012-05-21 Ken Brown <kbrown@cornell.edu>
10772 * xgselect.c (xg_select): Fix first argument in call to 'select'
10775 2012-05-20 Ken Brown <kbrown@cornell.edu>
10777 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
10778 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
10780 2012-05-19 Ken Brown <kbrown@cornell.edu>
10782 * xfns.c (x_in_use): Remove `static' qualifier.
10783 * xterm.h (x_in_use): Declare.
10784 * xgselect.c: Include xterm.h.
10785 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
10786 and `display_arg' (bug#9754).
10788 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
10790 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
10792 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
10793 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
10795 2012-05-18 Eli Zaretskii <eliz@gnu.org>
10797 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
10799 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
10800 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
10802 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
10803 reference to image_cache->refcount.
10804 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
10806 2012-05-17 Juri Linkov <juri@jurta.org>
10808 * search.c (Fword_search_regexp, Fword_search_backward)
10809 (Fword_search_forward, Fword_search_backward_lax)
10810 (Fword_search_forward_lax): Move functions to isearch.el
10811 (bug#10145, bug#11381).
10813 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
10815 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
10817 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
10819 * lread.c (init_obarray): Declare Qt and Qnil as special.
10821 2012-05-14 Glenn Morris <rgm@gnu.org>
10823 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
10824 Put "libexec" before "bin", for the sake of init_callproc_1.
10826 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
10828 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
10830 * unexaix.c: Port to more-recent AIX compilers.
10831 (report_error, report_error_1, make_hdr, copy_sym)
10832 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
10833 Make arguments const char *, not char *, to avoid violations of C
10834 standard and to fix some AIX warnings reported by Gilles Pion.
10836 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10838 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
10839 already have overlays loaded.
10840 (handle_single_display_spec): Before returning without displaying
10841 fringe bitmap, synchronize the bidi iterator with the main display
10842 iterator, by calling iterate_out_of_display_property.
10843 (iterate_out_of_display_property): Detect buffer iteration by
10844 testing that it->string is a Lisp string.
10845 (get_next_display_element): When the current object is exhausted,
10846 and there's something on it->stack, call set_iterator_to_next to
10847 proceed with what's on the stack, instead of returning zero.
10848 (set_iterator_to_next): If called at the end of a Lisp string,
10849 proceed to consider_string_end without incrementing string
10850 position. Don't increment display vector index past the end of
10851 the display vector. (Bug#11417)
10852 (pos_visible_p): Don't report a position visible when move_it_to
10853 stopped at the last line of window, which happens to be scanned
10854 backwards by the bidi iteration. (Bug#11464)
10856 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10858 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
10859 and right-margin display specs even if the spec is invalid or we
10860 are on a TTY, and thus unable to display on the fringes.
10861 That's because the text with the property will not be displayed anyway,
10862 so we need to signal to the caller that this is a "replacing"
10863 display spec. This fixes display when the spec is invalid or we
10866 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
10868 * unexaix.c (make_hdr): Fix typo in prototype.
10869 This bug broke the build on AIX. Problem reported by Gilles Pion.
10871 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
10873 * keyboard.c (kbd_buffer_get_event): Read special events also in
10874 batch mode. (Bug#11415)
10876 2012-05-12 Glenn Morris <rgm@gnu.org>
10878 * ns.mk: Update for ns_appbindir no longer having trailing "/".
10880 2012-05-12 Eli Zaretskii <eliz@gnu.org>
10882 * lisp.mk (lisp): Add newcomment.elc.
10884 2012-05-12 Glenn Morris <rgm@gnu.org>
10886 * Makefile.in (MKDIR_P): New, set by configure.
10887 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
10889 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
10891 Remove unused function hourglass_started.
10892 * dispextern.h (hourglass_started):
10893 * w32fns.c (hourglass_started):
10894 * xdisp.c (hourglass_started): Remove.
10896 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
10898 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
10899 Update dependencies.
10901 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
10903 * xgselect.c (xg_select): Put maxfds+1 into a var.
10904 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
10906 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
10908 2012-05-10 Dave Abrahams <dave@boostpro.com>
10910 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
10911 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
10913 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
10915 * dbusbind.c (xd_registered_buses): New internal Lisp object.
10916 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
10917 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
10918 Initialize xd_registered_buses.
10920 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
10922 Untag more efficiently if USE_LSB_TAG.
10923 This is based on a proposal by YAMAMOTO Mitsuharu in
10924 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
10925 For an admittedly artificial (nth 8000 longlist) benchmark on
10926 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
10927 Emacs's overall text size by 1%.
10928 * lisp.h (XUNTAG): New macro.
10929 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
10930 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
10931 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
10932 * eval.c (Fautoload):
10933 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
10934 * frame.h (XFRAME): Use XUNTAG.
10936 Port recent dbusbind.c changes to 32-bit --with-wide-int.
10937 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
10938 Remove unportable assumptions about print widths of types like
10940 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
10941 intptr_t when converting between pointer and integer, to avoid GCC
10942 warnings about wrong width.
10944 2012-05-09 Eli Zaretskii <eliz@gnu.org>
10946 * w32proc.c (new_child): Force Windows to reserve only 64KB of
10947 stack for each reader_thread, instead of defaulting to 8MB
10948 determined by the linker. This avoids failures in creating
10949 subprocesses on Windows 7, see the discussion in this thread:
10950 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
10952 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
10954 Fix up display of the *Minibuf-0* buffer in the mini window.
10955 * keyboard.c (read_char): Don't clear the echo area if there's no
10957 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
10958 contents of *Minibuf-0*) if there's no message displayed in its stead.
10960 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
10962 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
10965 2012-05-06 Chong Yidong <cyd@gnu.org>
10967 * lisp.mk (lisp): Update.
10969 2012-05-05 Jim Meyering <meyering@redhat.com>
10971 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
10973 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
10975 * data.c (PUT_ERROR): New macro.
10976 (syms_of_data): Use it. Add new error type `user-error'.
10977 * undo.c (user_error): New function.
10978 (Fprimitive_undo): Use it.
10979 * print.c (print_error_message): Adjust print style for `user-error'.
10980 * keyboard.c (user_error): New function.
10981 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
10983 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
10985 Do not limit current-time-string to years 1000..9999.
10986 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
10987 (Fcurrent_time_string): Support any year that is supported by the
10988 underlying localtime representation. Don't use asctime, as it
10989 has undefined behavior for years outside the range -999..9999.
10991 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
10993 Fix race conditions involving setenv, gmtime, localtime, asctime.
10994 Without this fix, interrupts could mess up code that uses these
10995 nonreentrant functions, since setting TZ invalidates existing
10996 tm_zone or tzname values, and since most of these functions return
10997 pointers to static storage.
10998 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
10999 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
11000 Grow the critical sections to include not just invoking
11001 localtime/gmtime, but also accessing these functions' results
11002 including their tm_zone values if any, and any related TZ setting.
11003 (format_time_string): Last arg is now struct tm *, not struct tm **,
11004 so that the struct tm is saved in the critical section.
11005 All callers changed. Simplify allocation of initial buffer, partly
11006 motivated by the fact that memory allocation needs to be outside
11007 the critical section.
11009 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
11011 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
11012 with RESET_INTERVAL.
11014 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
11015 Remove duplicated buffer name initialization.
11017 2012-05-02 Jim Meyering <jim@meyering.net>
11019 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
11021 * xfns.c (x_window): Use xstrdup (Bug#11375).
11023 2012-05-02 Eli Zaretskii <eliz@gnu.org>
11025 * xdisp.c (pos_visible_p): If already at a newline from the
11026 display string before the 'while' loop, don't walk back the glyphs
11027 from it3.glyph_row. Solves assertion violation when the display
11028 string begins with a newline (egg.el). (Bug#11367)
11030 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
11032 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
11035 2012-05-01 Glenn Morris <rgm@gnu.org>
11037 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
11038 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
11039 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
11040 All were removed before 23.1.
11042 * dispnew.c: Remove HAVE_LIBNCURSES test;
11043 it is always true on relevant platforms.
11045 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
11046 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
11048 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
11050 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
11052 * .gdbinit (xpr): Remove checks for no longer existing misc types.
11053 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
11056 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
11058 Do not avoid creating empty evaporating overlays (Bug#9642).
11059 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
11060 That is, do not delete an evaporating overlay if it becomes
11061 empty after its bounds are adjusted to fit within its buffer.
11062 This fix caused other problems, and I'm reverting it until we get
11063 to the bottom of them.
11065 2012-04-27 Chong Yidong <cyd@gnu.org>
11067 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
11069 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11071 * xdisp.c (pos_visible_p): If the window start position is beyond
11072 ZV, start the display from buffer beginning. Prevents assertion
11073 violation in init_iterator when the minibuffer window is scrolled
11074 via the scroll bar.
11076 * window.c (window_scroll_pixel_based): Likewise.
11078 2012-04-27 Chong Yidong <cyd@gnu.org>
11080 * keymap.c (where_is_internal): Doc fix (Bug#10872).
11082 2012-04-27 Glenn Morris <rgm@gnu.org>
11084 * fileio.c (Fcopy_file, Fset_file_selinux_context):
11085 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
11087 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11089 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
11090 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
11092 2012-04-26 Eli Zaretskii <eliz@gnu.org>
11094 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
11095 display element, check also the underlying string or buffer
11096 character. (Bug#11341)

11101 running on Windows 9X/Me.
11103 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
11105 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.

11126 Do not create empty overlays with the evaporate property (Bug#9642).
11127 * buffer.c (Fmove_overlay): Delete an evaporating overlay
11128 if it becomes empty after its bounds are adjusted to fit within
11129 its buffer. Without this fix, in a nonempty buffer (let ((o
11130 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
11131 yields an empty overlay that has the evaporate property, which is
11132 not supposed to happen.

11155 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
11156 (__malloc_size_t, __malloc_ptrdiff_t):
11157 Remove. All uses removed, replaced by the definiens if needed,
11158 since we can assume C89 or better now.

11247 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
11249 * sysdep.c [__FreeBSD__]: Minor cleanups.
11250 (list_system_processes, system_process_attributes) [__FreeBSD__]:
11251 Use Emacs indenting style more consistently. Avoid some casts.
11252 Use 'double' consistently rather than mixing 'float' and 'double'.

11256 * sysdep.c (list_system_processes, system_process_attributes):
11257 Add implementation for FreeBSD (Bug#5243).

11263 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
11265 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
11266 It is never used otherwise.
11268 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
11270 * print.c (print_preprocess): Only check print_depth if print-circle

11277 * process.c (wait_reading_process_output): If EIO occurs on a pty,
11278 set the status to "failed" and ensure that sentinel is run.
11280 2012-04-20 Glenn Morris <rgm@gnu.org>
11282 * process.c (Fset_process_inherit_coding_system_flag)
11283 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

11311 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
11312 -Wunused-result, -Wunused-variable. This should go away once
11313 the Emacs and Gnulib regex code is merged.

11333 New extern decls, to avoid calling undeclared functions.
11334 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
11335 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
11336 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
11337 (NEED_MEM_INSERT): New macro.
11338 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
11339 Remove one incorrect comment and fix another.

11375 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
11376 * s/netbsd.h, s/sol2-6.h:
11377 Remove definition of GC_MARK_STACK, since the default now works.
11378 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:

11406 2012-04-11 Daniel Colascione <dancol@dancol.org>
11408 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
11409 against is gone. It's better to use vfork now so that when Cygwin
11410 gains a new, working vfork, we use it automatically (bug#10398).
11412 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

11462 (Fdefvar): Caller changed.
11464 * callint.c (Finteractive, Fcall_interactively):
11465 * minibuf.c (Fread_variable): Callers changed.
11467 2012-04-09 Eli Zaretskii <eliz@gnu.org>
11469 * xdisp.c (set_cursor_from_row): If the display string appears in
11470 the buffer at position that is closer to point than the position
11471 after the display string, display the cursor on the first glyph of
11472 the display string. Fixes cursor display when a 'display' text
11473 property immediately follows invisible text. (Bug#11094)
11475 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
11477 composite.c: use 'double' consistently
11478 * composite.c (get_composition_id): Use 'double' consistently
11479 instead of converting 'float' to 'double' and vice versa; this is
11480 easier to understand and avoids a GCC warning.
11482 2012-04-09 Glenn Morris <rgm@gnu.org>
11484 * Makefile.in: Generate leim-list with bootstrap-emacs, in
11485 preparation for dumping it with emacs. (Bug#4789)

11529 [!WINDOWSNT]: New macros.
11530 (init_libxml2_functions, libxml2_loaded_p): New functions.
11531 (parse_region): Call fn_xmlCheckVersion instead of using the macro
11532 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
11533 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
11534 Calls xmlCleanupParser only if libxml2 was loaded (or statically
11536 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
11537 Call init_libxml2_functions before calling libxml2 functions.
11538 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
11540 * emacs.c: Don't include libxml/parser.h.
11541 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
11542 xmlCleanupParser directly.
11544 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
11546 2012-04-07 Eli Zaretskii <eliz@gnu.org>
11548 * indent.c (Fvertical_motion): If there is a display string at
11549 point, use it.vpos to compute how many lines to backtrack after
11550 move_it_to point. (Bug#11133)
11552 2012-04-06 Eli Zaretskii <eliz@gnu.org>
11554 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
11555 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
11556 about subtle differences between FETCH_CHAR* and STRING_CHAR*
11557 macros related to unification of CJK characters. For the details,
11558 see the discussion following the message here:
11559 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
11561 2012-04-04 Chong Yidong <cyd@gnu.org>
11563 * keyboard.c (Vdelayed_warnings_list): Doc fix.
11565 2012-04-01 Eli Zaretskii <eliz@gnu.org>
11567 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
11568 instead of alloca. (Bug#11138)
11570 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
11572 * w32menu.c (is_simple_dialog): Properly check lisp types.
11575 2012-03-31 Eli Zaretskii <eliz@gnu.org>
11577 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
11578 position we get to after a call to move_it_to fails the
11579 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
11580 only if we wind up in a string from display property. (Bug#11063)
11582 * window.c (Fdelete_other_windows_internal): Invalidate the row
11583 and column information about mouse highlight, so that redisplay
11584 restores it after reallocating the glyph matrices. (Bug#7464)
11586 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
11587 string comes from a `display' text property, use the buffer
11588 position of that property as if we actually saw that position in
11590 (move_it_by_lines): Remove the assertion that
11591 "it->current_x == 0 && it->hpos == 0" which can be legitimately
11592 violated when there's a before-string at the beginning of a line.
11595 2012-03-30 Eli Zaretskii <eliz@gnu.org>
11597 * xdisp.c (append_space_for_newline): If the default face was
11598 remapped, use the remapped face for the appended newline.
11599 (extend_face_to_end_of_line): Use the remapped default face for
11600 extending the face to the end of the line.
11601 (display_line): Call extend_face_to_end_of_line when the default
11602 face was remapped. (Bug#11068)
11604 2012-03-29 Eli Zaretskii <eliz@gnu.org>
11606 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
11608 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
11610 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
11612 2012-03-27 Glenn Morris <rgm@gnu.org>
11614 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
11617 2012-03-26 Kenichi Handa <handa@m17n.org>
11619 * dispextern.h (struct glyph): Fix previous change. Change the
11620 bit length of glyphless.ch to 25 (Bug#11082).
11622 2012-03-26 Chong Yidong <cyd@gnu.org>
11624 * keyboard.c (Vselection_inhibit_update_commands): New variable.
11625 (command_loop_1): Use it; inhibit selection update for
11626 handle-select-window too (Bug#8996).
11628 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
11630 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
11632 2012-03-25 Kenichi Handa <handa@m17n.org>
11634 * dispextern.h (struct glyph): Change the bit length of
11635 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
11637 2012-03-24 Eli Zaretskii <eliz@gnu.org>
11639 * s/ms-w32.h (tzname): Include time.h before redirecting to
11640 _tzname. Fixes the MSVC build. (Bug#9960)
11642 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
11644 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
11647 * xterm.c (XTread_socket): Only modify handling_signal if
11648 !SYNC_INPUT. (Bug#11080)
11650 2012-03-23 Eli Zaretskii <eliz@gnu.org>
11652 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
11653 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
11654 when fetching a multibyte character consumes more bytes than
11655 CHAR_BYTES returns, due to unification of CJK characters in
11656 string_char. (Bug#11073)
11658 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
11660 * process.c (wait_reading_process_output): Handle pty disconnect
11661 by refraining from sending oneself a SIGCHLD (bug#10933).
11663 2012-03-22 Chong Yidong <cyd@gnu.org>
11665 * dispextern.h (struct it): New member string_from_prefix_prop_p.
11667 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
11668 Mark string as coming from a prefix property.
11669 (handle_face_prop): Use default face for prefix strings (Bug#4281).
11670 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
11672 2012-03-21 Chong Yidong <cyd@gnu.org>
11674 * xfaces.c (Vface_remapping_alist): Doc fix.
11676 2012-03-20 Eli Zaretskii <eliz@gnu.org>
11678 * w32proc.c (Fw32_set_console_codepage)
11679 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
11682 2012-03-20 Chong Yidong <cyd@gnu.org>
11684 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
11685 to reflect default non-nil value of redisplay-dont-pause.
11687 2012-03-19 Kenichi Handa <handa@m17n.org>
11689 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
11690 it fit in a valid range (Bug#11003).
11692 2012-03-18 Eli Zaretskii <eliz@gnu.org>
11694 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
11695 that is not from display property, accept the row as a "cursor
11696 row" if one of the string's character has a non-nil `cursor'
11697 property. Fixes cursor positioning when there are newlines in
11698 overlay strings, e.g. in icomplete.el. (Bug#11035)
11700 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
11702 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
11704 2012-03-12 Chong Yidong <cyd@gnu.org>
11706 * eval.c (inhibit_lisp_code): Rename from
11707 inhibit_window_configuration_change_hook; move from window.c.
11709 * xfns.c (unwind_create_frame_1, Fx_create_frame):
11710 * window.c (run_window_configuration_change_hook)
11711 (syms_of_window): Callers changed.

11717 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
11719 2012-03-10 Chong Yidong <cyd@gnu.org>
11721 * frame.c (other_visible_frames): Don't assume the selected frame
11722 is visible (Bug#10955).
11724 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
11726 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).

11730 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
11731 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
11734 2012-03-03 Glenn Morris <rgm@gnu.org>
11736 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
11738 2012-03-02 Eli Zaretskii <eliz@gnu.org>
11740 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
11741 position past the first glyph_row that ends at ZV. (Bug#10902)
11742 (redisplay_window, next_element_from_string): Fix typos in
11744 (redisplay_window): Pass to move_it_vertically the margin in
11745 pixels, not in screen lines.
11747 2012-03-02 Glenn Morris <rgm@gnu.org>
11749 * buffer.c (buffer-list-update-hook): Doc fix.
11751 2012-02-29 Eli Zaretskii <eliz@gnu.org>
11753 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
11754 push_it before setting up the iterator for the first overlay
11755 string, even if we have an empty string loaded.
11756 (next_overlay_string): If there's an empty string on the iterator
11757 stack, pop the stack. (Bug#10903)
11759 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
11761 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
11762 Suggested by Stefan Monnier in
11763 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
11764 * alloc.c (widen_to_Lisp_Object): New static function.
11765 (mark_memory): Also mark Lisp_Objects by fetching pointer words
11766 and widening them to Lisp_Objects. This would work even if
11767 USE_LSB_TAG is defined and wide integers are used, which might
11768 happen in a future version of Emacs.
11770 2012-02-25 Chong Yidong <cyd@gnu.org>
11772 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
11775 * xselect.c (Fx_selection_exists_p): Doc fix.
11776 (x_clipboard_manager_save_all): Print an informative message
11777 before saving to clipboard manager.
11779 2012-02-24 Chong Yidong <cyd@gnu.org>
11781 * keyboard.c (process_special_events): Handle all X selection
11782 requests in kbd_buffer, not just the next one (Bug#8869).
11784 2012-02-23 Chong Yidong <cyd@gnu.org>
11786 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
11787 call when setting menu-bar-lines and tool-bar-lines parameters.
11788 (unwind_create_frame_1): New helper function.
11790 * window.c (inhibit_window_configuration_change_hook): New var.
11791 (run_window_configuration_change_hook): Obey it.
11792 (syms_of_window): Initialize it.
11794 2012-02-22 Chong Yidong <cyd@gnu.org>
11796 * xterm.c (x_draw_image_relief): Add missing type check for
11797 Vtool_bar_button_margin (Bug#10743).
11799 2012-02-21 Chong Yidong <cyd@gnu.org>
11801 * fileio.c (Vfile_name_handler_alist): Doc fix.
11803 * buffer.c (Fget_file_buffer): Protect against invalid file
11804 handler return value.
11806 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
11808 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
11809 when computing $valmask.
11811 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
11812 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
11813 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
11814 It's useless in that case, and it can cause problems on hosts
11815 that allocate halves of EMACS_INT values separately.
11816 Reported by Dan Horák. Diagnosed by Andreas Schwab in
11817 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
11818 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
11819 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
11820 it avoids undefined behavior on hosts where shifting right by more
11821 than the word width has undefined behavior.
11823 2012-02-19 Chong Yidong <cyd@gnu.org>
11825 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
11826 (Funhandled_file_name_directory, Ffile_name_as_directory)
11827 (Fdirectory_file_name, Fexpand_file_name)
11828 (Fsubstitute_in_file_name): Protect against invalid file handler
11829 return values (Bug#10845).
11831 2012-02-18 Eli Zaretskii <eliz@gnu.org>
11833 * .gdbinit (pitx): Fix incorrect references to fields of the
11836 2012-02-17 Chong Yidong <cyd@gnu.org>
11838 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
11840 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
11842 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
11843 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
11845 2012-02-15 Chong Yidong <cyd@gnu.org>
11847 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
11848 marked as special. Also, starting docstrings with * is obsolete.
11850 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
11852 * gnutls.c (emacs_gnutls_write): Fix last change.

11856 * gnutls.c (emacs_gnutls_write): Set errno appropriately for
11859 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
11861 * keymap.c (Fsingle_key_description): Handle char ranges.
11863 2012-02-12 Chong Yidong <cyd@gnu.org>
11865 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
11866 as that creates a dangerous corner case.
11868 * window.c (Fdelete_window_internal): Invalidate the mouse
11869 highlight (Bug#9904).
11871 2012-02-12 Glenn Morris <rgm@gnu.org>
11873 * xselect.c (Fx_own_selection_internal)
11874 (Fx_get_selection_internal, Fx_disown_selection_internal)
11875 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
11876 * nsselect.m (Fx_own_selection_internal)
11877 (Fx_disown_selection_internal, Fx_selection_exists_p)
11878 (Fx_selection_owner_p, Fx_get_selection_internal):
11879 Sync docs and argument specs with the xselect.c versions.
11881 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
11883 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
11885 2012-02-11 Eli Zaretskii <eliz@gnu.org>
11887 * w32select.c (Fx_selection_exists_p): Sync doc string and
11888 argument list with xselect.c. (Bug#10783)
11890 * w16select.c (Fx_selection_exists_p): Sync doc string and
11891 argument list with xselect.c. (Bug#10783)
11893 2012-02-10 Glenn Morris <rgm@gnu.org>
11895 * fns.c (Fsecure_hash): Doc fix.
11897 2012-02-09 Kenichi Handa <handa@m17n.org>
11899 * coding.c (produce_chars): Fix updating of src_end (Bug#10701).
11901 2012-02-07 Chong Yidong <cyd@gnu.org>
11903 * buffer.c (Fbuffer_local_variables)
11904 (buffer_lisp_local_variables): Handle unbound vars correctly;
11905 don't let Qunbound leak into Lisp.
11907 2012-02-07 Glenn Morris <rgm@gnu.org>
11909 * image.c (Fimagemagick_types): Doc fix.
11911 * image.c (imagemagick-render-type): Change it from a lisp object
11912 to an integer. Move the doc here from the lisp manual.
11913 Treat all values not equal to 0 the same.
11915 2012-02-06 Chong Yidong <cyd@gnu.org>
11917 * doc.c (store_function_docstring): Avoid applying docstring of
11918 alias to base function (Bug#2603).

11925 2012-02-04 Chong Yidong <cyd@gnu.org>
11927 * nsterm.m: Declare a global (Bug#10694).
11929 2012-02-04 Eli Zaretskii <eliz@gnu.org>
11931 * w32.c (get_emacs_configuration_options):
11932 Include --enable-checking, if specified, in the return value.
11934 2012-02-04 Martin Rudalics <rudalics@gmx.at>
11936 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
11937 after rounding frame sizes. (Bug#9723)
11939 2012-02-04 Eli Zaretskii <eliz@gnu.org>
11941 * keyboard.c (adjust_point_for_property): Don't position point
11942 before BEGV. (Bug#10696)
11944 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
11946 Handle overflow when computing char display width (Bug#9496).
11947 * character.c (char_width): Return EMACS_INT, not int.
11948 (char_width, c_string_width): Check for overflow when
11949 computing the width; this is possible now that individual
11950 characters can have unbounded width. Problem introduced
11951 by merge from Emacs 23 on 2012-01-19.
11953 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
11955 * dbusbind.c (Fdbus_register_method): Mention the return value
11956 :ignore in the docstring.
11958 2012-02-02 Glenn Morris <rgm@gnu.org>
11960 * callproc.c (Fcall_process, Fcall_process_region): Doc fix.
11962 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:
11963 Unconditionally set to t. (Bug#10673)

11968 2012-02-02 Kenichi Handa <handa@m17n.org>
11970 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
11971 0, do not call append_composite_glyph.
11973 2012-02-02 Kenichi Handa <handa@m17n.org>
11975 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
11977 (x_produce_glyphs): If the component of a composition is a null
11978 string, set it->pixel_width to 1 to avoid zero-width glyph.
11980 2012-02-01 Eli Zaretskii <eliz@gnu.org>
11982 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
11983 first 2 arguments are identical. This makes inserting large
11984 output from a subprocess an order of magnitude faster on
11985 MS-Windows, where all sbrk'ed memory is always contiguous.
11987 2012-01-31 Glenn Morris <rgm@gnu.org>
11989 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

12515 * xdisp.c (redisplay_window): If cursor row is not fully visible
12516 after recentering, and scroll-conservatively is set to a large
12517 number, scroll window by a few more lines to make the cursor fully
12518 visible and out of scroll-margin. (Bug#10105)
12519 (start_display): Don't move to the next line if the display should
12520 start at a newline that is part of a display vector or an overlay
12521 string. (Bug#10119)

12600 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
12601 Otherwise, valgrind does not work on some platforms.
12602 Problem reported by Andreas Schwab in
12603 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
12604 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
12605 is set, removing the need for VIRT_ADDRESS_VARIES.
12606 (PURE_P): Use a more-efficient implementation that needs just one
12607 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
12608 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
12609 to 4 (xorl, subq, cmpq, setbe).
12610 * alloc.c (pure): Always extern now, since that's the
12611 VIRT_ADDR_VARIES behavior.
12612 (PURE_POINTER_P): Use a single comparison, not two, for
12613 consistency with the new puresize.h.
12614 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
12615 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

12621 (erase_phys_cursor, update_window_cursor, show_mouse_face)
12622 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
12623 behave as if the cursor position were at the window margin.
12625 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
12626 and the cursor position is out of bounds, behave as if the cursor
12627 position were at the window margin. (Bug#10075)
12629 2011-11-18 Chong Yidong <cyd@gnu.org>
12631 * window.c (Fwindow_combination_limit): Make first argument

12650 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
12652 * xdisp.c (row_hash): New function, body extracted from
12653 compute_line_metrics.
12654 (compute_line_metrics): Call row_hash, instead of computing the
12657 * dispnew.c (verify_row_hash): Call row_hash for computing the
12658 hash code of a row, instead of duplicating code from xdisp.c.
12660 * dispextern.h (row_hash): Add prototype.
12662 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

12690 (Fsplit_window_internal, saved_window)
12691 (Fset_window_configuration, save_window_save): Rename all
12692 occurrences of window_nest to window_combination_limit.

12698 2011-11-14 Eli Zaretskii <eliz@gnu.org>
12700 * xdisp.c (display_line): Move the call to
12701 highlight_trailing_whitespace before the call to
12702 compute_line_metrics, since the latter needs to see the final
12703 faces of all the glyphs to compute ROW's hash value.
12704 Fixes assertion violations in row_equal_p. (Bug#10035)
12706 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
12708 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
12709 just return (bug#10044).
12711 2011-11-12 Eli Zaretskii <eliz@gnu.org>
12713 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
12714 with user-defined heap size. Bump the default size of the temacs
12715 heap to 27MB, to avoid memory warning when running temacs.
12716 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
12718 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
12719 current_matrix and desired_matrix. (Bug#9990)
12720 (verify_row_hash) [XASSERTS]: New function.
12721 (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify
12722 that the hash value of glyph rows is correct.

12765 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
12767 Avoid some portability problems by eschewing 'extern inline' functions.
12768 The trivial performance wins aren't worth the portability hassles; see
12769 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
12771 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

12777 making these static again.
12778 (offset_intervals, temp_set_point_both, temp_set_point)
12779 (copy_intervals_to_string): No longer inline.
12780 * xdisp.c (window_text_bottom_y, window_box_width)

12837 * xmenu.c (cleanup_widget_value_tree): New function.
12838 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
12839 calling free_menubar_widget_value_tree directly (Bug#9830).

12845 (window_box_width, window_box_left, window_box_left_offset)
12846 (window_box_right, window_box_right_offset): Declare extern.
12847 Otherwise, these inline functions do not conform to C99 and
12848 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
12849 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
12850 * intervals.c (adjust_intervals_for_insertion)

12853 (static_offset_intervals): Remove.
12854 (offset_intervals): Rewrite using the old contents of
12855 static_offset_intervals. The old version didn't conform to C99
12856 because an extern inline function contained a reference to an
12857 identifier with static linkage.

12909 * nsfns.m: Declare image_cache_refcount if GLYPH_DEBUG.
12910 (unwind_create_frame): New function (Bug#9943).
12911 (Fx_create_frame): Restructure code to be more similar to the one in
12912 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).

12928 Support MSVC build with newer versions of Visual Studio.
12929 * makefile.w32-in (TAGS-gmake): Don't use $(patsubst ...), as
12930 Nmake barfs on that. Use $(OBJ*_c) variables instead, defined on

12934 which are not supported by MSVC.
12935 (Lisp_Symbol, Lisp_Misc_Any, Lisp_Marker, Lisp_Misc_Overlay)

12951 [_MSC_VER]: Include sys/timeb.h, sys/stat.h, and signal.h.
12952 (fstat, stat, utime) [_MSC_VER]: Redirect to their sys_* cousins.
12953 (malloc, free, realloc, calloc) [_MSC_VER]: Always redirect to the
12955 (alloca) [_MSC_VER]: Define to _alloca.
12957 * lisp.h (DECL_ALIGN) [_MSC_VER]: Define for MSVC.
12959 * regex.c <re_char> [_MSC_VER]: A separate definition for MSVC.
12961 2011-11-04 Eli Zaretskii <eliz@gnu.org>
12963 * xdisp.c (note_mouse_highlight): If either of
12964 previous/next-single-property-change returns nil, treat that as
12965 the beginning or the end of the buffer. (Bug#9955)
12967 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
12969 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or
12970 label is not null (Bug#9951).
12971 (xg_tool_item_stale_p): Handle the fact that wimage and/or wlbl

12979 2011-11-03 Eli Zaretskii <eliz@gnu.org>
12981 * xdisp.c (note_mouse_highlight): Initialize `area'. (Bug#9947)
12983 * w32fns.c (unwind_create_frame): If needed, free the glyph
12984 matrices of the partially constructed frame. (Bug#9943)

12987 2011-11-01 Eli Zaretskii <eliz@gnu.org>
12989 * xdisp.c (mouse_face_from_buffer_pos): Fix a typo in a comment.
12990 Don't stop backward scan on the continuation glyph, even though
12991 its CHARPOS is positive.
12992 (mouse_face_from_buffer_pos, note_mouse_highlight):
12993 Rename cover_string to disp_string.
12995 2011-11-01 Martin Rudalics <rudalics@gmx.at>
12997 * window.c (temp_output_buffer_show): Don't use
12998 Vtemp_buffer_show_specifiers.
12999 (Vtemp_buffer_show_specifiers): Remove unused variable.
13001 2011-10-30 Eli Zaretskii <eliz@gnu.org>
13003 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
13004 past the beginning of the current glyph matrix.
13006 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
13008 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.
13009 (x_error_handler): Ignore BadMatch for X_SetInputFocus for
13010 HAVE_GTK3 (Bug#9869).
13012 * gtkutil.c (xg_win_to_widget, xg_event_is_for_menubar): Initialize
13013 type to GDK_NOTHING so valgrind does not complain (Bug#9901).
13015 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
13017 * xterm.c: Declare x_handle_net_wm_state to return int.
13018 (handle_one_xevent): Check if we are iconified but don't have
13019 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
13020 (get_current_wm_state): Return non-zero if not hidden,
13021 check for _NET_WM_STATE_HIDDEN (Bug#9893).

13028 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
13029 so that this new function doesn't get optimized away by a
13030 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
13032 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
13034 * frame.h (MOUSE_HL_INFO): Remove excess parens.
13036 2011-10-29 Eli Zaretskii <eliz@gnu.org>
13038 Fix the `xbytecode' command.
13039 * .gdbinit (xprintbytestr): New command.
13040 (xwhichsymbols): Rename from `which'; all callers changed.
13041 (xbytecode): Print the byte-code string as well.
13043 2011-10-29 Kim Storm <storm@cua.dk>
13045 * alloc.c (which_symbols): New function.
13047 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
13049 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
13052 2011-10-29 Glenn Morris <rgm@gnu.org>
13054 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
13055 Not clear what it was for, and it causes various bugs. (Bug#9839)
13057 2011-10-28 Eli Zaretskii <eliz@gnu.org>
13059 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
13060 possible random value that matches one of those tested as
13061 condition to clear the mouse face.
13063 2011-10-28 Chong Yidong <cyd@gnu.org>
13065 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
13067 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
13069 * window.c (make_window): Initialize phys_cursor_on_p.
13071 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
13073 * lisp.h (struct Lisp_Symbol): Update comments.
13075 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
13077 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
13079 2011-10-28 Eli Zaretskii <eliz@gnu.org>
13081 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
13082 <oslsachem@gmail.com> for helping to debug this.
13084 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
13085 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
13086 (g_b_init_get_glyph_outline_w): New static variables.
13087 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)

13090 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
13092 (w32font_open_internal, compute_metrics):
13093 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
13094 instead of calling the "wide" APIs directly.
13096 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
13098 * w32.h (syms_of_w32font): Add prototype.
13100 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
13102 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
13103 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
13104 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
13105 (Fmove_to_window_line): Doc fix.
13107 2011-10-27 Chong Yidong <cyd@gnu.org>
13109 * process.c (make_process): Set gnutls_state to NULL.
13111 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
13112 non-NULL, regardless of GNUTLS_INITSTAGE.
13113 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
13114 an error. Set process slots as soon as we allocate them.
13116 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
13118 2011-10-27 Chong Yidong <cyd@gnu.org>
13120 * gnutls.c (emacs_gnutls_deinit): New function.

13124 * process.c (make_process): Initialize GnuTLS credentials to NULL.
13125 (deactivate_process): Call emacs_gnutls_deinit.
13127 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
13129 * image.c (x_create_x_image_and_pixmap):
13130 * w32.c (sys_rename, w32_delayed_load):
13131 * w32font.c (fill_in_logfont):

13137 extracted from Fw32_default_color_map.
13138 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
13140 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
13142 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
13144 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
13146 * keyboard.c (test_undefined): New function (bug#9751).
13147 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
13149 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
13151 * sysdep.c (init_sys_modes): Fix the check for the controlling
13152 terminal (Bug#6649).
13154 2011-10-20 Eli Zaretskii <eliz@gnu.org>
13156 * dispextern.h (struct bidi_it): New member next_en_type.
13158 * bidi.c (bidi_line_init): Initialize the next_en_type member.
13159 (bidi_resolve_explicit_1): When next_en_pos is valid for the
13160 current character, check also for next_en_type being WEAK_EN.
13161 (bidi_resolve_weak): Don't enter the expensive loop if the current
13162 position is before next_en_pos. Record the bidi type of the first
13163 non-ET, non-BN character we find, in addition to its position.
13164 (bidi_level_of_next_char): Invalidate next_en_type when
13165 next_en_pos is over-stepped.
13167 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
13169 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
13170 * editfns.c: Rewrite current-time-zone so that it invokes
13171 the equivalent of (format-time-string "%Z") to get the time zone name.
13172 This fixes a bug when the time zone name contains characters that
13173 need converting from the system time locale to Emacs internal format.
13174 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
13175 that patch fixed format-time-string to do the conversion, but
13176 I forgot to fix current-time-zone.
13177 (format_time_string): New function, containing most of
13178 what Fformat_time_string used to contain.
13179 (Fformat_time_string): Rewrite in terms of format_time_string.
13180 This doesn't change this function's behavior.
13181 (current-time-zone): Rewrite to use format_time_string.
13182 This fixes the bug reported by Michael Schierl in
13183 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
13184 Jason Rumney's 2007-06-07 change worked around this bug, but
13186 * systime.h (tzname, timezone): Remove no-longer-used declarations.
13188 2011-10-19 Eli Zaretskii <eliz@gnu.org>
13190 * xdisp.c (start_display): If the character at POS is displayed
13191 via a display vector, reset IT->current.dpvec_index to zero.
13192 (try_window_reusing_current_matrix): If a line ends in a display
13193 vector or the next line starts in a display vector, continue
13194 redrawing the window even though the character position of
13195 start_row was reached.
13198 2011-10-18 Chong Yidong <cyd@gnu.org>
13200 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
13201 with nobreak-char-display too.
13203 2011-10-18 Eli Zaretskii <eliz@gnu.org>
13205 Fix part 3 of bug#9771.
13206 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
13207 (bidi_resolve_neutral): Don't enter the expensive loop looking for
13208 non-neutral characters if the current character is a paragraph
13209 separator (a.k.a. Newline). This avoids running the same
13210 expensive loop twice, once when we consume the preceding newline
13211 and the other time when the line actually needs to be displayed.
13212 Avoid the loop when we see neutrals on the base embedding level
13213 following a character whose directionality is the same as the
13214 paragraph's. This avoids running the expensive loop when a line
13215 ends in a long sequence of neutrals, like control characters.
13216 Add assertion against STRONG_AL type. Slightly rearrange code
13217 that determines the type of a neutral given the first non-neutral
13219 (bidi_level_of_next_char): Set next_en_pos to zero when
13220 invalidating its info.
13222 2011-10-17 Eli Zaretskii <eliz@gnu.org>
13224 * xdisp.c (push_display_prop): Determine whether to record string
13225 or buffer position by IT->string, not by IT->method. Allow
13226 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
13227 (move_it_vertically_backward): Don't look for character position
13228 immediately after the newline when in a continuation line.
13231 2011-10-15 Martin Rudalics <rudalics@gmx.at>
13233 * window.c (coordinates_in_window): Rewrite and delabelize
13234 vertical border check. (Bug#5357) (Bug#9618)
13236 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
13238 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
13239 errors in XSetWindowBorder (bug#9310).
13241 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
13243 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
13244 avoid crash when xmalloc overrun checking is enabled.
13246 2011-10-13 Eli Zaretskii <eliz@gnu.org>
13248 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
13249 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
13250 cursor motion with <left> and <right> arrow keys.
13252 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
13253 some callers set that themselves.
13255 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13257 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
13258 display string and the previous row comes from the same string and
13259 is empty. (Bug#9739) (Bug#9738)
13261 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
13263 * doc.c (get_doc_string): Encode file name (bug#9735).
13265 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13267 * bidi.c (bidi_level_of_next_char):
13268 * xdisp.c (get_visually_first_element): Remove old incorrect
13269 comments regarding the Unicode Line Separator character.
13271 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
13273 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
13275 * alloc.c (Fgc_status): Do not access beyond zombies array
13276 boundary if nzombies > MAX_ZOMBIES.
13277 * alloc.c (dump_zombies): Add missing format specifier.
13279 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
13281 * xdisp.c (set_cursor_from_row): Simplify conditionals,
13282 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
13284 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
13285 Some packages use them to denote characters with modifiers.
13287 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
13289 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
13290 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
13291 matching a pp-number. Rename parameter var to var1.
13293 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
13295 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
13297 2011-10-08 Glenn Morris <rgm@gnu.org>
13299 * callint.c (Fcall_interactively): Give a more explicit error for the
13300 'c' case with a non-character input. (Bug#8479)
13302 2011-10-08 Eli Zaretskii <eliz@gnu.org>
13304 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
13306 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
13307 lines that are hscrolled on the left.
13309 * dispnew.c (buffer_posn_from_coords): Account for a possible
13310 presence of header-line. (Bug#4426)
13312 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
13314 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
13315 Don't advertise functionality which we discourage or doesn't work.
13317 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
13319 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
13320 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
13321 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
13322 this makes Emacs dump core during garbage collection on rare
13323 occasions. sizeof is obviously inferior to offsetof here, so
13324 stick with offsetof.
13325 (GC_POINTER_ALIGNMENT): New macro.
13326 (mark_memory): Omit 3rd (offset) arg; caller changed.
13327 Don't assume EMACS_INT alignment is the same as pointer alignment.
13329 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
13331 * keyboard.c (read_key_sequence_remapped): New var.
13332 (read_key_sequence): Compute remapping in the right buffer.
13333 (command_loop_1): Use read_key_sequence's remapping directly.
13335 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
13337 * dired.c (file_name_completion): Don't expand file name.
13338 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
13339 before checking file name handler.
13341 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
13342 they've been requested explicitly (bug#9591).
13344 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
13346 * keymap.c (Fsingle_key_description): Use make_specified_string
13347 instead of build_string to build string from push_key_description.
13350 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13352 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
13353 This fixes a Y2038 bug on 64-bit hosts.
13354 * buffer.c (reset_buffer):
13355 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
13356 (Fclear_buffer_auto_save_failure):
13357 Use 0, not -1, to represent an unset failure time, since time_t
13358 might not be signed.
13360 Remove dependency on glibc malloc internals.
13361 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13362 Move back here from lisp.h, but with their new implementations.
13363 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13364 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
13365 * charset.c (charset_table_init): New static var.
13366 (syms_of_charset): Use it instead of xmalloc. This removes a
13367 dependency on glibc malloc internals. See Eli Zaretskii's comment in
13368 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
13369 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13370 Move back to alloc.c.
13371 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13372 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
13374 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
13376 * nsterm.m (windowDidResize): Call x_set_window_size only when
13377 ns_in_resize is true. Otherwise set pixelwidth/height and
13378 call change_frame_size (Bug#9628).
13380 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13382 Port --enable-checking=all to Fedora 14 x86-64.
13383 * charset.c (syms_of_charset): Also account for glibc malloc's
13384 internal overhead when calculating the initial malloc maximum.
13386 Port --enable-checking=all to Fedora 14 x86.
13387 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13389 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
13390 (overrun_check_realloc, overrun_check_free):
13391 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
13392 That way, xmalloc returns a properly-aligned pointer even if
13393 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
13394 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
13395 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
13396 into account when calculating the initial malloc maximum.
13397 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13398 Move here from alloc.c, so that charset.c can use it too.
13399 Properly align; the old code wasn't right for common 32-bit hosts
13400 when configured with --enable-checking=all.
13401 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13402 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
13404 2011-09-29 Eli Zaretskii <eliz@gnu.org>
13406 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
13409 2011-09-28 Eli Zaretskii <eliz@gnu.org>
13411 * xdisp.c (compute_display_string_end): If there's no display
13412 string at CHARPOS, return -1.
13414 * bidi.c (bidi_fetch_char): When compute_display_string_end
13415 returns a negative value, treat the character as a normal
13416 character not covered by a display string. (Bug#9624)
13418 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
13420 * lread.c (Fread_from_string): Fix typo in docstring.
13422 2011-09-27 Eli Zaretskii <eliz@gnu.org>
13424 * xdisp.c (handle_invisible_prop): If invisible text ends on a
13425 newline, reseat the iterator instead of bidi-iterating there one
13426 character at a time. (Bug#9610)
13427 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
13428 TO_CHARPOS if the bidi iterator is at base embedding level.
13430 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
13432 * lread.c (readevalloop): Use correct code for NBSP.
13433 (read1): Likewise. (Bug#9608)
13435 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
13437 * dbusbind.c (Fdbus_register_signal): When service is not
13438 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
13440 2011-09-25 Glenn Morris <rgm@gnu.org>
13442 * buffer.c (truncate-lines): Doc fix.
13444 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
13446 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
13447 (Fset_window_next_buffers): Doc fix.
13449 2011-09-24 Glenn Morris <rgm@gnu.org>
13451 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
13453 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
13455 Fix minor problems found by static checking.
13456 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
13457 * indent.c (Fvertical_motion): Fix == vs = typo.
13459 2011-09-24 Eli Zaretskii <eliz@gnu.org>
13461 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
13462 Default value is now t. Doc fix.
13464 * indent.c (Fvertical_motion): Compute and apply the overshoot
13465 logic when moving up, not only when moving down. Fix the
13466 confusing name and values of the it_overshoot_expected variable;
13467 logic changes accordingly. (Bug#9254) (Bug#9549)
13469 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
13470 CHARPOS is covered by a display string which includes newlines.
13471 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
13472 is covered by a display string with embedded newlines.
13474 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
13476 * dbusbind.c (Fdbus_register_signal): Add match rule to
13477 Vdbus_registered_objects_table. (Bug#9581)
13478 (Fdbus_register_method, Vdbus_registered_objects_table):
13481 2011-09-24 Jim Meyering <meyering@redhat.com>
13483 do not ignore write error for any output size
13484 The previous change was incomplete.
13485 While it makes emacs --batch detect the vast majority of stdout
13486 write failures, errors were still ignored whenever the output size is
13487 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
13488 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
13489 && echo FAIL: ignored write error
13490 FAIL: ignored write error
13491 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
13492 && echo FAIL: ignored write error
13493 FAIL: ignored write error
13494 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
13496 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
13498 * emacs.c (Fkill_emacs): In noninteractive mode exit
13499 non-successfully if a write error occurred on stdout. (Bug#9574)
13501 2011-09-21 Eli Zaretskii <eliz@gnu.org>
13503 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
13506 * dispextern.h (struct it): Update the comment documenting what
13509 2011-09-20 Eli Zaretskii <eliz@gnu.org>
13511 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
13512 a display string, extend search for cursor position to end of row.
13513 (find_row_edges): If the row ends in a newline from a display
13514 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
13515 Handle the case of a display string with multiple newlines.
13516 (Fcurrent_bidi_paragraph_direction): Fix search for previous
13517 non-empty line. Fixes confusing cursor motion with arrow keys at
13518 the beginning of a line that starts with whitespace.
13520 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
13522 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
13525 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
13527 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
13528 boolean (Bug#9154).
13530 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13532 * xdisp.c (display_line): Record maximum and minimum buffer
13533 positions even if no glyphs were produced (e.g., by a zero-width
13534 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
13535 buffer positions that will be removed from the glyph row because
13537 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
13538 column is beyond frame width: don't subtract 1 "pixel" when
13539 computing width of the stretch.
13540 (reseat_at_next_visible_line_start): Undo the change made on
13541 2011-09-17 that saved paragraph information and restored it after
13542 the call to `reseat'. (Bug#9545)
13544 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13546 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
13547 and turn window cursor on if cleared (Bug#9415).
13549 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
13551 * search.c (boyer_moore): Take unibyte characters from pattern
13552 literally. (Bug#9458)
13554 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13556 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
13558 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
13560 Fix minor problem found by static checking.
13561 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
13562 initialized, to pacify gcc -Wuninitialized.
13564 * fileio.c: Report proper errno when syscall falls.
13565 (Finsert_file_contents): Save and restore errno,
13566 so that report_file_error outputs the correct diagnostic.
13567 (Fwrite_region) [CLASH_DETECTION]: Likewise.
13569 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13571 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
13573 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13575 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
13576 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
13578 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13580 * xdisp.c (reseat_at_next_visible_line_start): Keep information
13581 about the current paragraph and restore it after the call to reseat.
13583 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
13584 (bidi_find_paragraph_start): Search back for paragraph beginning
13585 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
13586 (bidi_move_to_visually_next): Only trigger paragraph-related
13587 computations when the last character is a newline or at EOB, not
13588 just any NEUTRAL_B. (Bug#9470)
13590 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
13591 truncated lines if point is covered by a display string. (Bug#9524)
13593 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
13595 * xselect.c: Relax test for outgoing X longs (Bug#9498).
13596 (cons_to_x_long): New function.
13597 (lisp_data_to_selection_data): Use it. Correct the test for
13598 short-versus-long data; it was negated. Break out of vector
13599 loop, for efficiency, when a long datum is discovered.
13601 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
13603 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
13605 2011-09-16 Eli Zaretskii <eliz@gnu.org>
13607 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
13608 GCC PR/17406) by declaring this function with external scope.
13610 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13612 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
13613 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
13615 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
13617 * editfns.c (Fformat): Correctly handle text properties on "%%".

13623 * term.c (encode_terminal_code):
13624 * composite.c (composition_update_it, get_composition_id):
13625 * xdisp.c (get_next_display_element)
13626 (fill_composite_glyph_string): Add comments about special meaning
13627 of TAB characters in a composition.
13629 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13631 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
13632 This occurs when processing a multibyte format.
13633 Problem reported by Wolfgang Jenker.
13635 2011-09-15 Johan Bockgård <bojohan@gnu.org>
13637 * xdisp.c (try_cursor_movement): Only check for exact match if
13638 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
13640 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13642 Remove unused external symbols.
13643 * dispextern.h (calc_pixel_width_or_height): Remove decl.
13644 * xdisp.c (calc_pixel_width_or_height): Now static.
13645 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
13646 * indent.c (check_display_width):
13647 * w32term.c: Fix comment to match code.
13648 * xterm.c, xterm.h (x_catching_errors): Remove.
13650 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13652 * xselect.c: Use signed conversions more consistently (Bug#9498).
13653 (selection_data_to_lisp_data): Assume incoming selection data are
13654 signed integers, not unsigned. This is to be consistent with
13655 outgoing selection data, which was modified to use signed integers
13656 in as part of the fix to Bug#9196 in response to Jan D.'s comment
13657 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
13658 expects long, not unsigned long.
13660 2011-09-14 Eli Zaretskii <eliz@gnu.org>
13662 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
13663 computation of loop end. Reported by Johan Bockgård
13666 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
13668 * frame.c (Fother_visible_frames_p): Function deleted.
13670 2011-09-12 Eli Zaretskii <eliz@gnu.org>
13672 * indent.c (compute_motion): Process display vector front to back
13673 rather than the other way around. (Bug#2496)
13675 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
13677 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
13679 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
13681 * minibuf.c (Fread_from_minibuffer): Doc fix.
13683 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13685 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
13686 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
13688 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
13690 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
13691 value for non-existent files.
13693 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13695 * fileio.c (Finsert_file_contents): If the file cannot be opened,
13696 set its "size" to -1. This will set the modtime_size field of
13697 the corresponding buffer to -1, which is what
13698 verify-visited-file-modtime expects for files that do not exist.
13701 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
13703 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
13705 * lisp.h: ... from here. push_key_description is no longer
13706 defined in keyboard.c, so its declaration should not be in
13707 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
13708 logically belongs with push_key_description.
13710 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
13712 * buffer.h: Include <sys/types.h> instead of <time.h>.
13713 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
13714 Problem reported by Herbert J. Skuhra.
13716 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
13718 * xml.c (parse_region): Make the parsing work for
13719 non-comment-starting XML files again (bug#9144).
13721 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
13723 * image.c (gif_load): Fix calculation of bottom and right corner.
13726 2011-09-10 Eli Zaretskii <eliz@gnu.org>
13728 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
13729 redisplay in small windows.
13731 2011-09-09 Eli Zaretskii <eliz@gnu.org>
13733 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
13735 2011-09-08 Martin Rudalics <rudalics@gmx.at>
13737 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
13738 Operate on live windows only.
13740 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
13742 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
13744 2011-09-07 Eli Zaretskii <eliz@gnu.org>
13746 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
13747 only under bidi iteration.
13749 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
13751 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
13753 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13755 isnan: Fix porting problem to Solaris 10 with bundled gcc.
13756 Without this fix, the command to link temacs failed due to an
13757 undefined symbol __builtin_isnan. This is because
13758 /usr/include/iso/math_c99.h #defines isnan(x) to
13759 __builtin_isnan(x), but the bundled gcc, which identifies itself
13760 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
13762 * floatfns.c (isnan): #undef, and then #define to a clone of
13764 (Fisnan): Always define, since it's always available now.
13765 (syms_of_floatfns): Always define isnan at the Lisp level.
13767 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13769 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
13771 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13773 * fileio.c: Fix bugs with large file offsets (Bug#9428).
13774 The previous code assumed that file offsets (off_t values) fit in
13775 EMACS_INT variables, which is not true on typical 32-bit hosts.
13776 The code messed up by falsely reporting buffer overflow in cases
13777 such as (insert-file-contents "big" nil 1 2) into an empty buffer
13778 when "big" contains more than 2**29 bytes, even though this
13779 inserts just one byte and does not overflow the buffer.
13780 (Finsert_file_contents): Store file offsets as off_t
13781 values, not as EMACS_INT values. Check for overflow when
13782 converting between EMACS_INT and off_t. When checking for
13783 buffer overflow or for overlap, take the offsets into account.
13784 Don't use EMACS_INT for small values where int suffices.
13785 When checking for overlap, fix a typo: ZV was used where
13786 ZV_BYTE was intended.
13787 (Fwrite_region): Don't assume off_t fits into 'long'.
13788 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
13790 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
13792 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
13794 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13796 sprintf-related integer and memory overflow issues (Bug#9412).
13798 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
13799 (esprintf, exprintf, evxprintf): New functions.
13800 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
13801 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
13802 (modify_event_symbol): Do not assume that the length of
13803 name_alist_or_stem is safe to alloca and fits in int.
13804 (Fexecute_extended_command): Likewise for function name and binding.
13805 (Frecursion_depth): Wrap around reliably on integer overflow.
13806 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
13807 since some callers pass EMACS_INT values.
13808 (Fsingle_key_description): Don't crash if symbol name contains more
13809 than MAX_ALLOCA bytes.
13810 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
13811 (get_minibuffer): Arg is now EMACS_INT, not int.
13812 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
13813 (esprintf, exprintf, evxprintf): New decls.
13814 * window.h (command_loop_level, minibuf_level): Reflect API changes.
13816 * dbusbind.c (signature_cat): New function.
13817 (xd_signature, Fdbus_register_signal):
13818 Do not overrun buffer; instead, report string overflow.
13820 * dispnew.c (add_window_display_history): Don't overrun buffer.
13821 Truncate instead; this is OK since it's just a log.
13823 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
13824 even if the time zone offset is outlandishly large.
13825 Don't mishandle offset == INT_MIN.
13827 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
13828 when creating daemon; the previous buffer-overflow check was incorrect.
13830 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
13831 which has the guts of the old verror function.
13833 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
13834 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
13836 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
13837 (font_unparse_xlfd): Don't blindly alloca long strings.
13838 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
13839 fits in int, when using sprintf. Use single snprintf to count
13840 length of string rather than counting it via multiple sprintfs;
13841 that's simpler and more reliable.
13842 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
13843 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
13844 sprintf, in case result does not fit in int.
13846 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
13847 (fontset_from_font): Print it.
13849 * frame.c (tty_frame_count): Now printmax_t, not int.
13850 (make_terminal_frame, set_term_frame_name): Print it.
13851 (x_report_frame_params): In X, window IDs are unsigned long,
13852 not signed long, so print them as unsigned.
13853 (validate_x_resource_name): Check for implausibly long names,
13854 and don't assume name length fits in 'int'.
13855 (x_get_resource_string): Don't blindly alloca invocation name;
13856 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
13859 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
13860 (xg_check_special_colors, xg_set_geometry):
13861 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
13863 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
13864 Use esprintf, not sprintf, in case result does not fit in int.
13866 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13867 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
13868 it as a large positive number.

13870 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13872 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
13873 in case result does not fit in int.
13875 * print.c (float_to_string): Detect width overflow more reliably.
13876 (print_object): Make sprintf buffer a bit bigger, to avoid potential
13877 buffer overrun. Don't assume list length fits in 'int'. Treat
13878 print length of 0 as 0, not as infinity; to be consistent with other
13879 uses of print length in this function. Don't overflow print length
13880 index. Don't assume hash table size fits in 'long', or that
13881 vectorlike size fits in 'unsigned long'.
13883 * process.c (make_process): Use printmax_t, not int, to format
13884 process-name gensyms.
13886 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
13888 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
13889 to avoid potential buffer overrun.
13891 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
13892 if X resource line is longer than 512 bytes.
13894 * xfns.c (x_window): Make sprintf buffer a bit bigger
13895 to avoid potential buffer overrun.
13897 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
13899 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
13901 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13903 Integer overflow fixes for scrolling, etc.
13904 Without these, Emacs silently mishandles large integers sometimes.
13905 For example, "C-u 4294967297 M-x recenter" was treated as if
13906 it were "C-u 1 M-x recenter" on a typical 64-bit host.
13908 * xdisp.c (try_window_id): Check Emacs fixnum range before
13909 converting to 'int'.
13911 * window.c (window_scroll_line_based, Frecenter):
13912 Check that an Emacs fixnum is in range before assigning it to 'int'.
13913 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
13914 values converted from Emacs fixnums.
13915 (Frecenter): Don't wrap around a line count if it is out of 'int'
13916 range; instead, treat it as an extreme value.
13917 (Fset_window_configuration, compare_window_configurations):
13918 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
13920 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
13921 that can exceed INT_MAX. Check that EMACS_INT value is in range
13922 before assigning it to the (possibly-narrower) index.
13923 (match_limit): Don't assume that a fixnum can fit in 'int'.
13925 * print.c (print_object): Use ptrdiff_t, not int, for index that can
13928 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
13929 (Fvertical_motion): Don't wrap around LINES values that don't fit
13930 in 'int'. Instead, treat them as extreme values. This is good
13931 enough for windows, which can't have more than INT_MAX lines anyway.
13933 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
13935 * Require libxml/parser.h to avoid compilation warning.
13937 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
13939 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
13940 since this reportedly can destroy thread storage.
13942 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
13944 * syntax.c (find_defun_start): Update all cache variables if
13945 exiting early (Bug#9401).
13947 2011-08-30 Eli Zaretskii <eliz@gnu.org>
13949 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
13951 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
13952 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
13953 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
13955 * term.c (tty_append_glyph): New function.
13956 (produce_stretch_glyph): Static function and its prototype deleted.
13958 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
13961 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
13963 * image.c (parse_image_spec): Check for nonnegative, not for positive,
13964 when checking :margin (Bug#9390).
13965 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
13966 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
13967 so that the name doesn't mislead. All uses changed.
13969 2011-08-28 Johan Bockgård <bojohan@gnu.org>
13971 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
13974 2011-08-27 Eli Zaretskii <eliz@gnu.org>
13976 * xdisp.c (move_it_to): Don't bail out early when reaching
13977 position beyond to_charpos, if we are scanning backwards.
13978 (move_it_vertically_backward): When DY == 0, make sure we get to
13979 the first character in the line after the newline.
13981 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
13983 * ccl.c: Improve and simplify overflow checking (Bug#9196).
13984 (ccl_driver): Do not generate an out-of-range pointer.
13985 (Fccl_execute_on_string): Remove unnecessary check for
13986 integer overflow, noted by Stefan Monnier in
13987 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
13988 Remove a FIXME that didn't need fixing.
13989 Simplify the newly-introduced buffer reallocation code.
13991 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
13993 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
13995 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
13997 Integer and memory overflow issues (Bug#9196).
13999 * doc.c (get_doc_string): Rework so that
14000 get_doc_string_buffer_size is the actual buffer size, rather than
14001 being 1 less than the actual buffer size; this makes xpalloc more
14004 * image.c (x_allocate_bitmap_record, cache_image):
14005 * xselect.c (Fx_register_dnd_atom):
14006 Simplify previous changes by using xpalloc.
14008 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
14009 since either will do and ptrdiff_t is convenient with xpalloc.
14011 * charset.c (charset_table_size)
14012 (struct charset_sort_data.priority): Now ptrdiff_t.
14013 (charset_compare): Don't overflow if priorities differ greatly.
14014 (Fsort_charsets): Don't assume list length fits in int.
14015 Check for size-calculation overflow when allocating sort data.
14016 (syms_of_charset): Allocate an initial charset table that is
14017 just under 64 KiB, to avoid problems with glibc malloc and mmap.
14019 * cmds.c (internal_self_insert): Check for size-calculation overflow.
14021 * composite.h (struct composition.glyph_len): Now int, not unsigned.
14022 The actual value is always <= INT_MAX, and leaving it unsigned made
14023 overflow checking harder.
14025 * dispextern.h (struct glyph_matrix.rows_allocated)
14026 (struct face_cache.size): Now ptrdiff_t, for convenience in use
14027 with xpalloc. The values are still always <= INT_MAX.
14029 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
14031 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
14032 (SAFE_NALLOCA): New macro.
14034 * region-cache.c (struct boundary.pos, find_cache_boundary)
14035 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
14036 (set_cache_region, invalidate_region_cache)
14037 (revalidate_region_cache, know_region_cache, region_cache_forward)
14038 (region_cache_backward, pp_cache):
14039 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
14040 so that ptrdiff_t * can be passed to xpalloc.
14041 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
14042 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
14043 (pp_cache): Don't assume cache_len fits in int.
14044 * region-cache.h: Adjust extern decls to match.
14046 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
14047 EMACS_INT, since either will do, for xpalloc.
14049 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
14050 (xnmalloc, xnrealloc, xpalloc): New functions.
14052 * bidi.c (bidi_shelve_header_size): New constant.
14053 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
14054 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
14056 * bidi.c (bidi_cache_shrink):
14057 * buffer.c (overlays_at, overlays_in, record_overlay_string)
14059 Don't update size of array until after memory allocation succeeds,
14060 because xmalloc/xrealloc may not return.
14061 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
14062 now that we have proper integer overflow checking.
14063 (record_overlay_string, overlay_strings): Catch overflows when
14064 calculating size of overlay_str_buf.
14066 * callproc.c (Fcall_process): Check for size overflow when
14067 calculating size of args2.
14068 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
14069 Normally we prefer signed values, but sticking with ptrdiff_t would
14070 require adding more-complicated checks.
14072 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
14073 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
14074 Redo buffer-overflow calculations to avoid integer overflow.
14075 Add a FIXME comment where memory seems to be over-allocated.
14077 * character.c (Fstring): Check for size-calculation overflow.
14079 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
14080 unnecessary integer overflow. Check for size overflow.
14081 (encode_coding_object): Don't update size until xmalloc succeeds.
14083 * composite.c (get_composition_id): Check for overflow in glyph
14084 length calculations.
14086 Integer and memory overflow fixes for display code.
14087 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
14088 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
14089 (scrolling_window): Check for overflow in size calculations.
14090 (line_draw_cost, realloc_glyph_pool, add_row_entry):
14091 Don't assume glyph table len fits in int.

14093 (row_table_size): Now ptrdiff_t, not int.
14094 (scrolling_window): Avoid overflow in size calculations.
14095 Don't update size until allocation succeeds.
14096 * fns.c (concat): Check for overflow in size calculations.
14097 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
14098 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.

14101 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
14102 (get_doc_string): Check for size calculation overflow.
14103 Don't update size until allocation succeeds.
14104 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
14105 EMACS_INT, where ptrdiff_t will do.
14106 (Fsubstitute_command_keys): Check for string overflow.
14108 * editfns.c (set_time_zone_rule): Don't assume environment length
14110 (message_length): Now ptrdiff_t, not int.
14111 (Fmessage_box): Don't update size until allocation succeeds.
14112 Don't assume message length fits in int.
14113 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
14115 * emacs.c (main): Do not reallocate argv, since there is a null at
14116 the end that can be overwritten, and this way there's no need to
14117 worry about size-calculation overflow.
14118 (sort_args): Check for size-calculation overflow.
14120 * eval.c (init_eval_once, grow_specpdl): Don't update size until
14122 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
14124 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
14125 (x_set_scroll_bar_width, x_figure_window_size):
14126 Check for integer overflow.
14127 (x_set_alpha): Do not assume XINT fits in int.
14129 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
14130 This is for the members text_lines, text_cols, total_lines, total_cols,
14131 where the system imposes an 'int' limit.
14133 * fringe.c (Fdefine_fringe_bitmap):
14134 Don't update size until alloc works.
14136 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
14137 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
14139 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
14140 Check for size-calculation overflow.
14141 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
14142 do, as we prefer signed integers.
14143 (id_to_widget.max_size, id_to_widget.used)
14144 (xg_store_widget_in_map, xg_remove_widget_from_map)
14145 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
14146 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
14147 Use and return ptrdiff_t, not int.
14148 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
14149 * gtkutil.h: Change prototypes to match the above.
14151 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
14152 are duplicate now that they've been promoted to lisp.h.
14153 (x_allocate_bitmap_record, x_alloc_image_color)
14154 (make_image_cache, cache_image, xpm_load):
14155 Don't update size until alloc is done.
14156 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
14158 Check for size calculation overflow.
14159 (ct_colors_allocated_max): New constant.
14160 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
14163 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
14164 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
14165 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
14166 Use ptrdiff_t, not int, to count maps.
14167 (read_char_minibuf_menu_prompt): Check for overflow in size
14168 calculations. Don't update size until allocation succeeds.
14169 Redo calculations to avoid overflow.
14170 * keyboard.h: Change prototypes to match the above.
14172 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
14174 (current_minor_maps): Check for size calculation overflow.
14175 * keymap.h: Change prototypes to match the above.
14177 * lread.c (read1, init_obarray): Don't update size until alloc done.
14179 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
14180 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
14182 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
14183 Now ptrdiff_t, not int.
14184 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

14188 in size calculation.
14190 * region-cache.c (move_cache_gap): Check for size calculation overflow.
14192 * scroll.c (do_line_insertion_deletion_costs): Check for size calc
14193 overflow. Don't bother calling xmalloc when xrealloc will do.
14195 * search.c (Freplace_match): Check for size calculation overflow.
14196 (Fset_match_data): Don't assume list lengths fit in 'int'.
14198 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
14199 for command line length. Do not attempt to address one before the
14200 beginning of an array, as that's not portable.
14202 * term.c (max_frame_lines): Remove; unused.
14203 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
14205 (encode_terminal_code, calculate_costs): Check for size
14206 calculation overflow.
14207 (encode_terminal_code): Use ptrdiff_t, not int, to record glyph
14208 table lengths and related sizes. Don't update size until alloc
14209 done. Redo calculations to avoid overflow.
14210 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
14212 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
14213 subtracting pointers.
14214 (gobble_line): Check for overflow more carefully. Don't update size
14217 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
14218 Don't update size until alloc done.
14219 Redo size calculations to avoid overflow.

14221 (main) [DEBUG]: Fix typo in invoking tparam1.
14223 * xdisp.c (store_mode_line_noprop_char, x_consider_frame_title):
14224 Use ptrdiff_t, not int, for sizes.
14225 (store_mode_line_noprop_char): Don't update size until alloc done.
14227 * xfaces.c (lface_id_to_name_size, Finternal_make_lisp_face):
14228 Use ptrdiff_t, not int, for sizes.
14229 (Finternal_make_lisp_face, cache_face):
14230 Check for size calculation overflow.
14231 (cache_face): Treat size calculation overflows as if they were
14232 memory exhaustion (the usual treatment), rather than aborting.
14234 * xfns.c (x_encode_text, x_set_name_internal)
14235 (Fx_change_window_property): Use ptrdiff_t, not int, to count
14236 sizes, since they can exceed INT_MAX in size. Check for size
14237 calculation overflow.
14239 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
14240 (xg_select): Check for size calculation overflow.
14241 Don't update size until alloc done.
14243 * xrdb.c (get_environ_db): Don't assume path length fits in int,
14244 as sprintf is limited to int lengths.
14246 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
14247 (X_LONG_MIN): New macros.
14248 Use them to make the following changes clearer.
14249 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
14250 This change doesn't affect the value now, but it may help remind
14251 future maintainers not to raise the value too much later.
14252 (SELECTION_QUANTUM): Remove, replacing with ...
14253 (selection_quantum): ... new function, which avoids overflow.
14255 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
14256 assumption that selection length fits in 'int'.
14257 (x_reply_selection_request, x_handle_selection_request)
14258 (x_get_window_property, receive_incremental_selection)
14259 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
14260 (lisp_data_to_selection_data, clean_local_selection_data):
14261 Use ptrdiff_t, not int, to record length of selection.
14262 (x_reply_selection_request, x_get_window_property)
14263 (receive_incremental_selection, x_property_data_to_lisp):
14264 Redo calculations to avoid overflow.
14265 (x_reply_selection_request): When sending hint, ceiling it at
14266 X_LONG_MAX rather than relying on wraparound overflow to send
14268 (x_get_window_property, receive_incremental_selection)
14269 (lisp_data_to_selection_data, x_property_data_to_lisp):
14270 Check for size-calculation overflow.
14271 (x_get_window_property, receive_incremental_selection)
14272 (lisp_data_to_selection_data, Fx_register_dnd_atom):
14273 Don't store size until memory allocation succeeds.
14274 (x_get_window_property): Plug memory leak on memory exhaustion.
14275 Don't double-block input; malloc is safe here. Don't assume 2**34
14276 - 4 fits in unsigned long. Add an xassert to check
14277 XGetWindowProperty overflow. Be more careful about overflow
14278 calculations, and distinguish size from memory overflow better.
14279 (receive_incremental_selection): When tracing, don't assume
14280 unsigned int is less than INT_MAX.
14281 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
14282 harmful) conversions of unsigned short to int.
14283 (lisp_data_to_selection_data): Don't assume that integers
14284 in the range -65535 through -1 fit in an X unsigned short.
14285 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
14286 result parameters unless successful. Rely on cons_to_unsigned
14287 to report problems with elements; the old code wasn't right anyway.
14288 (x_check_property_data): Check for int overflow; we cannot use
14289 a wider type due to X limits.

14322 * lisp.h (hash_lookup, hash_put):
14323 * minibuf.c (Ftest_completion):
14324 Use ptrdiff_t for hash table indexes, not int (which is too
14325 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
14326 32-bit --with-wide-int hosts).
14328 * charset.c (Fdefine_charset_internal): Check for integer overflow.
14329 Add a FIXME comment about memory leaks.
14330 (syms_of_charset): Don't assume xmalloc returns.

14334 * character.h (CHAR_WIDTH):
14335 * indent.c (MULTIBYTE_BYTES_WIDTH):
14336 Use sanitize_char_width to avoid undefined and/or bad behavior
14337 with outlandish widths.
14338 * character.h (sanitize_tab_width): Rename from sanitize_width,
14339 now that we have two such functions. All uses changed.

14357 * xterm.c: Don't go over XClientMessageEvent limit.
14358 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
14359 (x_send_scroll_bar_event): Likewise. Check that the size does not
14360 exceed limits imposed by XClientMessageEvent, as well as the usual
14361 ptrdiff_t and size_t limits.
14363 * keyboard.c: Overflow, signedness and related fixes.
14364 (make_lispy_movement): Use same integer type in forward decl
14365 that is used in the definition.
14366 (read_key_sequence, keyremap_step):
14367 Change bufsize argument back to int, undoing my 2011-03-30 change.
14368 We prefer signed types, and int is wide enough here.
14369 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
14370 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
14371 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
14372 length, not size_t. Use ptrdiff_t for index, not int.
14373 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
14374 possibility of integer overflow.
14376 Overflow, signedness and related fixes for images.

14400 since parse_image_check makes sure they fit into int.
14401 (png_load, gif_load, svg_load_image):
14402 Prefer int to unsigned where either will do.
14403 (tiff_handler): New function, combining the cores of the
14404 old tiff_error_handler and tiff_warning_handler.
14405 This function is rewritten to use vsnprintf and thereby avoid
14406 stack buffer overflows. It uses only the features of vsnprintf
14407 that are common to both POSIX and native Microsoft.
14408 (tiff_error_handler, tiff_warning_handler): Use it.
14409 (tiff_load, gif_load, imagemagick_load_image):
14410 Don't assume :index value fits in 'int'.
14411 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
14412 (imagemagick_load_image): Check that crop parameters fit into
14413 the integer types that MagickCropImage accepts. Don't assume
14414 Vimagemagick_render_type has a nonnegative value. Don't assume
14415 size_t fits in 'long'.
14416 (gs_load): Use printmax_t to print the widest integers possible.

14430 (handle_single_display_spec): If the display spec is of the form
14431 `(space ...)', and specifies display in the text area, return 2
14433 (try_cursor_movement): Check for the need to scroll more
14434 accurately, and prefer exact match for point under bidi.
14435 Don't advance `row' beyond the last row of the window.

14452 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
14453 buffers, return left-to-right.
14454 (set_cursor_from_row): Consider candidate row a win if its glyph
14455 represents a newline and point is on that newline. Fixes cursor
14456 positioning on the newline at EOL of R2L text within L2R
14457 paragraph, and vice versa.
14458 (try_cursor_movement): Check continued rows, in addition to
14459 continuation rows. Fixes unwarranted scroll when point enters a
14460 continued line of R2L text within an L2R paragraph, or vice versa.
14461 (cursor_row_p): Consider the case of point being equal to
14462 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
14463 from the end of a short line to the beginning of a continued line
14464 of R2L text within L2R paragraph.
14465 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

14483 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
14484 extra slot even if the purpose is char-code-property-table.
14486 2011-08-23 Eli Zaretskii <eliz@gnu.org>
14488 * xdisp.c (redisplay_window): When computing centering_position,
14489 account for the height of the header line. (Bug#8874)
14491 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
14492 instead of CHAR_TO_BYTE. Fixes a crash when a completion
14493 candidate is selected by the mouse, and that candidate has a
14494 composed character under the mouse.
14496 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
14497 coordinates reported by pos-visible-in-window-p for a composed
14498 character in column zero.
14500 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
14502 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
14504 2011-08-22 Eli Zaretskii <eliz@gnu.org>
14506 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
14507 consider it a hit if to_charpos is anywhere in the range of the
14508 composed buffer positions.
14510 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
14512 * image.c (gif_load): Don't assume that each subimage has the same
14513 dimensions as the base image. Handle disposal method that is
14514 "undefined" by the gif spec (Bug#9335).
14516 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
14518 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

14521 2011-08-19 Eli Zaretskii <eliz@gnu.org>
14523 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
14524 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
14525 from an Org mode buffer to a Speedbar frame.
14527 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
14528 a composition, take its buffer position from IT->cmp_it.charpos.
14529 Fixes cursor positioning at the beginning of a line that begins
14530 with a composed character.
14532 2011-08-18 Eli Zaretskii <eliz@gnu.org>
14534 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
14535 character bidirectional type, use STRONG_L instead. Fixes crashes
14536 in a buffer produced by `describe-categories'.
14538 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
14539 members before the level stack, so they would be saved and
14540 restored when copying iterator state. Fixes incorrect reordering
14541 around TABs covered by display properties.
14543 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
14545 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

14553 2011-08-17 Eli Zaretskii <eliz@gnu.org>
14555 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
14556 has no `load' handler, try opening the file locally. (Bug#9311)
14558 2011-08-16 Ken Brown <kbrown@cornell.edu>
14560 * gmalloc.c: Expand comment.
14562 2011-08-16 Eli Zaretskii <eliz@gnu.org>
14564 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
14565 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.

14610 * process.c (create_process): Call setup_process_coding_systems
14611 after the pid of the process is set to -1 (Bug#8162).
14613 2011-08-14 Eli Zaretskii <eliz@gnu.org>
14615 * xdisp.c (move_it_in_display_line_to): Don't invoke
14616 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
14617 ppos_it. Fixes vertical cursor motion when line beginning is
14618 covered by an image. (Bug#9296)
14620 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
14622 * nsterm.h (ns_run_ascript): Declare.

14626 (ns_run_ascript): New function.
14627 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
14628 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
14629 the event loop. Get status from as_status (Bug#7276).
14631 * nsterm.m (sendEvent): If event is NSApplicationDefined and
14632 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
14633 the event loop (Bug#7276).
14635 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>

14658 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
14659 (Fnetwork_interface_list): Allocate in increments of bytes instead
14660 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
14661 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
14663 (struct ifflag_def): notrailers is smart on OSX.
14664 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
14665 Get hardware address with getifaddrs if available.
14667 2011-08-12 Eli Zaretskii <eliz@gnu.org>
14669 * xdisp.c (iterate_out_of_display_property): xassert that
14670 IT->position is set to within IT->object's boundaries. Break from
14671 the loop as soon as EOB is reached; avoids infloops in redisplay
14672 when IT->position is set up wrongly due to some bug.
14673 Set IT->current to match the bidi iterator unconditionally.
14674 (push_display_prop): Allow GET_FROM_STRING as IT->method on
14675 entry. Force push_it to save on the stack the current
14676 buffer/string position, to be restored by pop_it. Fix flags in
14677 the iterator structure wrt the object coming from a display
14678 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
14679 properties. (Bug#9284)
14681 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
14683 * fontset.c (fontset_get_font_group): Add proper type checks.

14696 no-display-properties-and-no-overlays under bidi display.
14697 Set disp_pos in the bidi iterator to avoid searches for display
14698 properties and overlays.
14700 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
14702 * editfns.c (Fset_time_zone_rule): Document relationship with the

14708 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
14710 * composite.c (autocmp_chars): Don't reset point. That is done by
14711 restore_point_unwind (Bug#5984).
14713 2011-08-07 Juri Linkov <juri@jurta.org>
14715 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
14716 to show the arg `TIME' instead of `TIMEVAL'.
14718 2011-08-06 Eli Zaretskii <eliz@gnu.org>
14720 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
14721 display property strides EOL and includes a newline, as in
14722 longlines-mode. (Bug#9254)
14723 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
14724 word-wrap under bidirectional display. (Bug#9224)
14726 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
14727 is non-zero, even if the data buffer is NULL. Fixes a crash in
14728 vertical-motion with longlines-mode. (Bug#9254)
14730 2011-08-05 Eli Zaretskii <eliz@gnu.org>
14732 * bidi.c <bidi_cache_total_alloc>: Now static.
14733 (bidi_initialize): Initialize bidi_cache_total_alloc.
14735 * xdisp.c (display_line): Release buffer allocated for shelved bidi
14738 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
14739 amount allocated this far in `bidi_cache_total_alloc'.
14740 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
14741 non-zero, only free the data buffer without restoring the cache
14742 contents. All callers changed.
14744 * dispextern.h (bidi_unshelve_cache): Update prototype.
14746 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
14747 (move_it_in_display_line, move_it_to)
14748 (move_it_vertically_backward, move_it_by_lines): Replace the call
14749 to xfree to an equivalent call to bidi_unshelve_cache.
14750 (move_it_in_display_line_to): Fix logic of returning
14751 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
14753 2011-08-05 Eli Zaretskii <eliz@gnu.org>
14755 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
14756 came from a string character with a `cursor' property. (Bug#9229)
14758 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
14760 * Makefile.in (LIB_PTHREAD): New variable.
14761 (LIBES): Add LIB_PTHREAD (Bug#9216).
14763 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
14764 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
14766 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
14768 * regex.c (re_iswctype): Remove some redundant boolean conversions.
14770 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
14772 * xterm.c (x_find_topmost_parent): New function.
14773 (x_set_frame_alpha): Find topmost parent window with
14774 x_find_topmost_parent and set the property there also (bug#9181).
14775 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
14777 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
14779 * callproc.c (Fcall_process): Avoid vfork clobbering
14780 the local vars buffer, coding_systems, current_dir.
14782 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
14784 * keymap.c (Fmake_composed_keymap): Move to subr.el.
14786 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
14788 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
14789 so that it is not optimized away.
14791 * xdisp.c (compute_display_string_pos): Remove unused local.
14793 2011-08-02 Eli Zaretskii <eliz@gnu.org>
14795 Fix slow cursor motion and scrolling in large buffers with
14796 selective display, like Org Mode buffers. (Bug#9218)
14798 * dispextern.h (struct bidi_it): New member disp_prop_p.
14800 * xdisp.c: Remove one-slot cache of display string positions.
14801 (compute_display_string_pos): Accept an additional argument
14802 DISP_PROP_P; callers changed. Scan at most 5K characters forward
14803 for a display string or property. If found, set DISP_PROP_P
14806 * bidi.c (bidi_fetch_char): Accept an additional argument
14807 DISP_PROP_P, and pass it to compute_display_string_pos.
14808 Only handle text covered by a display string if DISP_PROP_P is returned
14809 non-zero. All callers of bidi_fetch_char changed.
14811 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
14813 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
14815 2010-12-03 Don March <don@ohspite.net>
14817 * keymap.c (Fdefine_key): Fix non-prefix key error message when
14818 last character M-[char] is translated to ESC [char] (bug#7541).
14820 2011-08-02 Kenichi Handa <handa@m17n.org>
14822 * lisp.h (uniprop_table): Extern it.
14824 * chartab.c (uniprop_table): Make it non-static.
14826 2011-08-01 Eli Zaretskii <eliz@gnu.org>
14828 * xdisp.c (forward_to_next_line_start): Accept additional argument
14829 BIDI_IT_PREV, and store into it the state of the bidi iterator had
14831 (reseat_at_next_visible_line_start): Use the bidi iterator state
14832 returned by forward_to_next_line_start to restore the state of
14833 it->bidi_it after backing up to previous newline. (Bug#9212)
14835 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
14837 * regex.c (re_comp): Protoize.
14838 (re_exec): Fix return type.
14839 (regexec): Fix type of `ret'. (Bug#9203)
14841 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14843 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
14844 This is needed if max-image-size is a floating-point number.
14846 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
14848 * print.c (print_object): Print empty symbol as ##.
14850 * lread.c (read1): Read ## as empty symbol.
14852 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
14854 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
14855 setting frame foreground color (Bug#9175).
14856 (x_set_background_color): Likewise.
14858 * nsmenu.m (-setText): Size tooltip dimensions precisely to
14859 contents (Bug#9176).
14860 (EmacsTooltip -init): Remove bezels and add shadows to
14863 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
14864 or scroll bar (Bug#8470).
14866 * nsfont.m (nsfont_open): Remove assignment to voffset and
14867 unnecessary vars hshink, expand, hd, full_height, min_height.
14868 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
14870 * nsterm.h (nsfont_info): Remove voffset field.
14872 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
14874 Implement strike-through and overline on NextStep (Bug#8863).
14876 * nsfont.m (nsfont_open): Use underline position provided by font,
14877 instead of hard-coded value of 2.
14878 (nsfont_draw): Call ns_draw_text_decoration instead.
14880 * nsterm.h: Add declaration for ns_draw_text_decoration.
14882 * nsterm.m (ns_draw_text_decoration): New function for drawing
14883 underline, overline, and strike-through.
14884 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
14885 ns_draw_text_decoration. Change treatment of cursor drawing to
14886 accommodate underlining, etc.
14888 2011-07-28 Eli Zaretskii <eliz@gnu.org>
14890 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
14893 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14895 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
14896 Without this fix, if a signal arrives just after memory fills up,
14897 'malloc' might be invoked reentrantly.
14899 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
14900 In other words, assume that every image size is allowed, on non-X
14901 hosts. This assumption is probably wrong, but it lets Emacs compile.
14903 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
14905 * regex.c (re_iswctype): Convert return values to boolean.
14907 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
14909 * xdisp.c (compute_display_string_pos): Don't use cached display
14910 string position if the buffer had its restriction changed.
14913 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14915 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
14917 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14919 Integer signedness and overflow and related fixes. (Bug#9079)
14921 * bidi.c: Integer size and overflow fixes.
14922 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
14923 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
14924 (bidi_cache_find_level_change, bidi_cache_ensure_space)
14925 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
14926 (bidi_find_other_level_edge):
14927 Use ptrdiff_t instead of EMACS_INT where either will do.
14928 This works better on 32-bit hosts configured --with-wide-int.
14929 (bidi_cache_ensure_space): Check for size-calculation overflow.
14930 Use % rather than repeated addition, for better worst-case speed.
14931 Don't set bidi_cache_size until after xrealloc returns, because it
14933 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
14934 (bidi_cache_ensure_space): Also check that the bidi cache size
14935 does not exceed that of the largest Lisp string or buffer. See Eli
14936 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
14938 * alloc.c (__malloc_size_t): Remove.
14939 All uses replaced by size_t. See Andreas Schwab's note
14940 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
14942 * image.c: Improve checking for integer overflow.
14943 (check_image_size): Assume that f is nonnull, since
14944 it is always nonnull in practice. This is one less thing to
14945 worry about when checking for integer overflow later.
14946 (x_check_image_size): New function, which checks for integer
14947 overflow issues inside X.
14948 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
14949 This removes the need for a memory_full check.
14950 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
14951 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
14952 (xbm_read_bitmap_data): Change locals back to 'int', since
14953 their values must fit in 'int'.
14954 (xpm_load_image, png_load, tiff_load):
14955 Invoke x_create_x_image_and_pixmap earlier,
14956 to avoid much needless work if the image is too large.
14957 (tiff_load): Treat overly large images as if
14958 x_create_x_image_and_pixmap failed, not as malloc failures.
14959 (gs_load): Use x_check_image_size.
14961 * gtkutil.c: Omit integer casts.
14962 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
14963 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
14965 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
14967 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
14968 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
14969 would wrongly return t on a 64-bit host.
14971 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
14972 The plain *_OVERFLOW macros run afoul of GCC bug 49705
14973 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
14974 and therefore cause GCC to emit a bogus diagnostic in some cases.
14976 * image.c: Integer signedness and overflow and related fixes.
14977 This is not an exhaustive set of fixes, but it's time to
14978 record what I've got.
14979 (lookup_pixel_color, check_image_size): Remove redundant decls.
14980 (check_image_size): Don't assume that arbitrary EMACS_INT values
14981 fit in 'int', or that arbitrary 'double' values fit in 'int'.
14982 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
14983 (tiff_load, imagemagick_load_image):
14984 Check for overflow in size calculations.
14985 (x_create_x_image_and_pixmap): Remove unnecessary test for
14986 xmalloc returning NULL; that can't happen.
14987 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
14988 (xpm_color_bucket): Use better integer hashing function.
14989 (xpm_cache_color): Don't possibly over-allocate memory.
14990 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
14991 (gif_memory_source):
14992 Use ptrdiff_t, not int or size_t, to record sizes.
14993 (png_load): Don't assume values greater than 2**31 fit in 'int'.
14994 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
14995 either works, as we prefer signed integers.
14996 (tiff_read_from_memory, tiff_write_from_memory):
14997 Return tsize_t, not size_t, since that's what the TIFF API wants.
14998 (tiff_read_from_memory): Don't fail simply because the read would
14999 go past EOF; instead, return a short read.
15000 (tiff_load): Omit no-longer-needed casts.
15001 (Fimagemagick_types): Don't assume size fits into 'int'.
15003 Improve hashing quality when configured --with-wide-int.
15004 * fns.c (hash_string): New function, taken from sxhash_string.
15005 Do not discard information about ASCII character case; this
15006 discarding is no longer needed.
15007 (sxhash-string): Use it. Change sig to match it. Caller changed.
15008 * lisp.h: Declare it.
15009 * lread.c (hash_string): Remove, since we now use fns.c's version.
15010 The fns.c version returns a wider integer if --with-wide-int is
15011 specified, so this should help the quality of the hashing a bit.
15013 * emacs.c: Integer overflow minor fix.
15014 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
15015 Define only if GNU_LINUX.
15016 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
15018 * dispnew.c: Integer signedness and overflow fixes.
15019 Remove unnecessary forward decls, that were a maintenance hassle.
15020 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
15022 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
15023 (scrolling_window): Use ptrdiff_t, not int, for byte count.
15024 (prepare_desired_row, line_draw_cost):
15025 Use int, not unsigned, where either works.
15026 (save_current_matrix, restore_current_matrix):
15027 Use ptrdiff_t, not size_t, where either works.
15028 (init_display): Check for overflow more accurately, and without
15029 relying on undefined behavior.
15031 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
15032 Remove, replacing with the new symbols in lisp.h. All uses changed.
15033 * fileio.c (make_temp_name):
15034 * filelock.c (lock_file_1, lock_file):
15035 * xdisp.c (message_dolog):
15036 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
15037 Use pMd etc. instead.
15038 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
15039 replacing the pWIDE etc. symbols removed from editfns.c.
15041 * keyboard.h (num_input_events): Now uintmax_t.
15042 This is (very slightly) less likely to mess up due to wraparound.
15045 * buffer.c: Integer signedness fixes.
15046 (alloc_buffer_text, enlarge_buffer_text):
15047 Use ptrdiff_t rather than size_t when either will do, as we prefer
15050 * alloc.c: Integer signedness and overflow fixes.
15051 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
15052 (__malloc_size_t): Default to size_t, not to int.
15053 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
15054 (Fgarbage_collect, mark_object_loop_halt, mark_object):
15055 Prefer ptrdiff_t to size_t when either would do, as we prefer
15057 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
15058 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
15059 Now const. Initialize with values that are in range even if char
15061 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
15062 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
15063 These functions do the right thing with sizes > 2**32.
15064 (check_depth): Now ptrdiff_t, not int.
15065 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
15066 Adjust to new way of storing sizes. Check for size overflow bugs
15068 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
15069 slightly wrong anyway, as it missed one instance of
15070 XMALLOC_OVERRUN_CHECK_OVERHEAD.
15071 (refill_memory_reserve): Omit needless cast to size_t.
15072 (mark_object_loop_halt): Mark as externally visible.
15074 * xselect.c: Integer signedness and overflow fixes.
15075 (Fx_register_dnd_atom, x_handle_dnd_message):
15076 Use ptrdiff_t, not size_t, since we prefer signed.
15077 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
15078 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
15079 x_dnd_atoms_size and x_dnd_atoms_length.
15081 * doprnt.c: Prefer signed to unsigned when either works.
15083 * doprnt.c (doprnt):
15085 * xdisp.c (vmessage):
15086 Use ptrdiff_t, not size_t, when using or implementing doprnt,
15087 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
15088 prefer signed arithmetic to avoid comparison confusion.
15089 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
15090 but is a bit tricky.
15092 Assume freestanding C89 headers, string.h, stdlib.h.
15093 * data.c, doprnt.c, floatfns.c, print.c:
15094 Include float.h unconditionally.
15095 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
15096 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
15097 * regex.c: Likewise for stddef.h, string.h.
15098 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
15099 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
15100 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
15101 (STDC_HEADERS): Remove obsolete defines.
15102 * sysdep.c: Include limits.h unconditionally.
15104 Assume support for memcmp, memcpy, memmove, memset.
15105 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
15106 * regex.c (memcmp, memcpy):
15107 Remove; we assume C89 now.
15109 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
15110 (__malloc_safe_bcopy): Remove; no longer needed.
15112 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
15113 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
15114 well either way, and we prefer signed to unsigned.
15116 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
15118 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
15119 closes the connection while we're reading (bug#9182).
15121 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
15123 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
15124 are specified (Bug#9168).
15126 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
15128 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
15129 Found by GCC static checking and --with-wide-int on a 32-bit host.
15131 2011-07-25 Eli Zaretskii <eliz@gnu.org>
15133 * xdisp.c (compute_display_string_pos): Fix logic of caching
15134 previous display string position. Initialize cached_prev_pos to
15135 -1. Fixes slow-down at the beginning of a buffer.
15137 2011-07-24 Eli Zaretskii <eliz@gnu.org>
15139 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
15140 for attrs[LFACE_FONTSET_INDEX].
15142 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
15144 * xml.c (parse_region): Remove unused local
15145 that was recently introduced.
15147 2011-07-23 Eli Zaretskii <eliz@gnu.org>
15149 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
15150 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
15152 * xdisp.c (move_it_in_display_line_to): Record the best matching
15153 position for TO_CHARPOS while scanning the line, and restore it on
15154 exit if none of the characters scanned was an exact match.
15155 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
15156 when exact match is impossible due to invisible text, and the
15157 lines are truncated.
15159 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
15161 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
15164 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15166 Fix a significant slow-down of cursor motion with C-n, C-p,
15167 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
15168 auto-repeat under bidi redisplay in fontified buffers.
15169 * xdisp.c (compute_stop_pos_backwards): New function.
15170 (next_element_from_buffer): Call compute_stop_pos_backwards to
15171 find a suitable prev_stop when we find ourselves before
15173 (reseat): Don't look for prev_stop, as that could mean a very long
15175 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
15176 <cached_disp_overlay_modiff>: Cache for last found display string
15178 (compute_display_string_pos): Return the cached position if asked
15179 about the same buffer in the same area of character positions, and
15180 the buffer wasn't changed since the time the display string
15181 position was cached.
15183 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15185 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
15186 is an integer, which is important for empty lines. (Bug#9149)
15188 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
15190 * frame.c (Fmodify_frame_parameters): In tty case, update the
15191 default face if necessary (Bug#4238).
15193 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
15195 * editfns.c (Fstring_to_char): No need to explain what a character
15196 is in the docstring (Bug#6576).
15198 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15200 * xml.c (parse_region): Make sure we always return a tree.
15202 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
15204 * xml.c (parse_region): If a document contains only comments,
15207 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15209 * xml.c (make_dom): Return comments, too.
15211 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
15214 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
15215 and the surrounding thread.
15216 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
15217 rather than fgets, and retry after EINTR. Otherwise, 'emacs
15218 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
15220 * s/openbsd.h (BROKEN_SIGIO): Define.
15221 * unexelf.c (unexec) [__OpenBSD__]:
15222 Don't update the .mdebug section of the Alpha COFF symbol table.
15224 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15226 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
15229 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
15231 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
15232 This fixes some race conditions on the permissions of any newly
15235 * alloc.c (valid_pointer_p): Use pipe, not open.
15236 This fixes some permissions issues when debugging.
15238 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
15239 If fchown fails to set both uid and gid, try to set just gid,
15240 as that is sometimes allowed. Adjust the file's mode to eliminate
15241 setuid or setgid bits that are inappropriate if fchown fails.
15243 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
15245 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
15246 to compare Lisp_Objects.

15251 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
15253 * lread.c (read_integer): Unread even EOF character.
15254 (read1): Likewise. Properly record start position of symbol.

15257 symbol character follows.
15259 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
15261 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
15262 This works around a problem with the previous change to Fcopy_file.
15263 Recent glibc declares fchown with __attribute__((warn_unused_result)),
15264 and without this change, GCC might complain about discarding
15265 fchown's return value.
15267 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
15269 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
15271 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
15273 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
15275 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
15277 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
15278 it's used from the C level.
15280 * process.c: Use the same condition for POLL_FOR_INPUT in both
15281 keyboard.c and process.c (bug#1858).
15283 2011-07-09 Lawrence Mitchell <wence@gmx.li>
15285 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
15286 (Fgnutls_boot): Use it.
15288 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
15290 * doc.c (Fsubstitute_command_keys): Revert last change.
15292 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
15294 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
15295 quotes the next character, and doesn't affect other longer
15296 sequences (bug#8935).
15298 * lread.c (syms_of_lread): Clarify that is isn't only
15299 `eval-buffer' and `eval-defun' that's affected by
15300 `lexical-binding' (bug#8460).
15302 2011-07-15 Eli Zaretskii <eliz@gnu.org>
15304 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
15305 bidi redisplay when a line includes both an image and is truncated.
15307 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
15309 Fix minor problems found by static checking.
15310 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
15311 (elsz): Now a signed constant, not a size_t var. We prefer signed
15312 types to unsigned, to avoid integer comparison confusion. Without
15313 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
15314 "cannot optimize loop, the loop counter may overflow", a symptom
15316 * indent.c (Fvertical_motion): Mark locals as initialized.
15317 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
15319 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>

15345 (display_string): If we need to ignore text properties of
15346 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
15347 original value of -1 will not work with bidi.)
15348 (compute_display_string_pos): First arg is now struct
15349 `text_pos *'; all callers changed. Support display properties on
15351 (compute_display_string_end): Support display properties on Lisp
15353 (init_iterator, reseat_1, reseat_to_string): Initialize the
15354 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
15355 when iterating on a string not from display properties).
15356 (compute_display_string_pos, compute_display_string_end):
15357 Fix calculation of the object to scan. Fixes an error when using
15359 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
15360 base_level_stop; instead, set base_level_stop to BEGV.
15361 Fixes crashes in vertical-motion.
15362 (next_element_from_buffer): Improve commentary for when
15363 the iterator is before prev_stop.
15364 (init_iterator): Initialize bidi_p from the default value of
15365 bidi-display-reordering, not from buffer-local value. Use the
15366 buffer-local value only if initializing for buffer iteration.

15387 parts of next_element_from_buffer, next_element_from_string, and
15388 next_element_from_c_string.
15389 (tool_bar_lines_needed, redisplay_tool_bar)
15390 (display_menu_bar): Force left-to-right direction. Add a FIXME
15391 comment for making that be controlled by a user option.

15400 (get_overlay_strings_1, push_display_prop): Set up the bidi
15401 iterator for displaying display or overlay strings.
15402 (forward_to_next_line_start): Don't use the shortcut if
15404 (back_to_previous_visible_line_start): If handle_display_prop
15405 pushed the iterator stack, restore the internal state of the bidi
15406 iterator by calling bidi_pop_it same number of times.
15407 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
15408 and we are bidi-iterating, don't decrement the iterator position;
15409 instead, set the first_elt flag in the bidi iterator, to produce
15411 (reseat_1): Remove redundant setting of string_from_display_prop_p.
15412 (push_display_prop): xassert that we are iterating a buffer.
15413 (push_it, pop_it): Save and restore paragraph_embedding member.
15414 (handle_single_display_spec, next_overlay_string)
15415 (get_overlay_strings_1, reseat_1, reseat_to_string)
15416 (push_display_prop): Set up the `unibyte' member of bidi_it.string
15417 correctly. Don't assume unibyte strings are not bidi-reordered.

15425 popping after iteration over a string that came from a display
15426 property. Fix a typo in popping stretch info. Add an assertion
15427 for verifying that the iterator position is in sync with the bidi
15429 (handle_single_display_spec, get_overlay_strings_1)

15443 (try_scrolling, redisplay_window, display_line): Use them when
15444 saving a temporary copy of the iterator and restoring it back.
15445 (back_to_previous_visible_line_start, reseat_1)

15481 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
15482 can now be zero (for strings); special values 0 and -1 were
15483 changed to -1 and -2, respectively.
15484 (bidi_char_at_pos): New function.
15485 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):

15518 (bidi_push_it, bidi_pop_it): Add prototypes.
15519 (struct iterator_stack_entry): New members bidi_p,
15520 paragraph_embedding, and from_disp_prop_p.

15568 Pass Qx_lost_selection_functions rather than
15569 Vx_lost_selection_functions to Frun_hook_with_args.
15571 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
15573 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
15574 The old code sometimes used this field without initializing it.
15576 * alloc.c (gc_sweep): Don't read past end of array.
15577 In theory, the old code could also have corrupted Emacs internals,
15578 though it'd be very unlikely.

15582 * character.c (Fcharacterp): Don't advertise optional ignored
15583 argument. (Bug#4026)

15841 (clone_per_buffer_values): Don't assume that

15843 This isn't true in general, and it's particularly not true
15844 if Emacs is configured with --with-wide-int.
15845 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
15846 New macros, used in the buffer.c change.

15880 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
15882 Random fixes. E.g., (random) never returned negative values.
15883 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
15884 subseconds part to the entropy, as that's a bit more random.
15885 Prefer signed to unsigned, since the signedness doesn't matter and
15886 in general we prefer signed. When given a limit, use a
15887 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
15888 latter isn't right if USE_2_TAGS_FOR_INTS.
15889 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
15890 not 0..VALMASK. Don't discard "excess" bits that random () returns.
15892 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
15894 * textprop.c (text_property_stickiness):
15895 Obey Vtext_property_default_nonsticky.

15900 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
15902 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
15903 This is more efficient than Ffile_directory_p and avoids a minor race.
15905 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
15907 * buffer.c (Foverlay_put): Say what the return value is
15910 * fileio.c (barf_or_query_if_file_exists): Check first if the file
15911 is a directory before asking whether to use the file name
15913 (barf_or_query_if_file_exists): Make the "File is a directory"
15914 error be more correct.
15916 * fns.c (Frequire): Remove the mention of the .gz files, since
15917 that's installation-specific, but keep the mention of
15918 `get-load-suffixes'.
15920 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
15922 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

15928 (syms_of_gnutls): Remove duplicate DEFSYM for
15929 Qgnutls_bootprop_verify_hostname_error, an error for
15930 Qgnutls_bootprop_verify_error (which is no longer used).
15932 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
15933 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
15934 Also (re)move comments that are misplaced or no longer relevant.
15936 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15938 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

15956 2011-07-02 Chong Yidong <cyd@stupidchicken.com>
15958 * keyboard.c (command_loop_1): If a down-mouse event is unbound,
15959 leave any prefix arg for the up event (Bug#1586).
15961 2011-07-02 Lars Magne Ingebrigtsen <larsi@gnus.org>
15963 * lread.c (syms_of_lread): Mention single symbols defined by
15964 `defvar' or `defconst' (bug#7154).
15966 * fns.c (Frequire): Mention .el.gz files (bug#7314).
15967 (Frequire): Mention get-load-suffixes.

15997 (syms_of_keymap): Defsubr make-composed-keymap.
15998 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

16027 (xgselect_initialize): Ditto.
16029 * process.c: Add defined (HAVE_GSETTINGS) for xgselect.h

16035 * eval.c (struct backtrace): Simplify and port the data structure.
16036 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
16037 signed bit field, as this assumption is not portable and it makes
16038 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
16039 "char debug_on_exit : 1" as this is not portable either; instead,
16040 use the portable "unsigned int debug_on_exit : 1". Remove unused
16041 member evalargs. Remove obsolete comments about cc bombing out.
16043 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

16137 Use gnulib's dup2 module instead of rolling our own.
16138 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.

16209 * print.c (printchar, strout): Check for string overflow.
16210 (PRINTPREPARE, printchar, strout):
16211 Don't set size unless allocation succeeds.
16213 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
16214 for sizes. Check for string overflow more accurately.
16215 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
16217 * macros.c: Integer and buffer overflow fixes.
16218 * keyboard.h (struct keyboard.kbd_macro_bufsize):
16219 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

16223 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
16225 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
16227 * lread.c: Integer overflow fixes.
16228 (read_integer): Radix is now EMACS_INT, not int,
16229 to improve quality of diagnostics for out-of-range radices.
16230 Calculate buffer size correctly for out-of-range radices.
16231 (read1): Check for integer overflow in radices, and in
16232 read-circle numbers.
16233 (read_escape): Avoid int overflow.
16234 (Fload, openp, read_buffer_size, read1)
16235 (substitute_object_recurse, read_vector, read_list, map_obarray):
16236 Use ptrdiff_t, not int, for sizes.

16251 2011-06-22 Leo Liu <sdl.web@gmail.com>
16253 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
16254 Move to minibuffer.el.
16256 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
16258 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
16259 The following patches are for when GLYPH_DEBUG && !XASSERT.
16260 * dispextern.h (trace_redisplay_p, dump_glyph_string):
16261 * dispnew.c (flush_stdout):
16262 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
16263 Mark as externally visible.
16264 * dispnew.c (check_window_matrix_pointers): Now static.
16265 * dispnew.c (window_to_frame_vpos):
16266 * xfns.c (unwind_create_frame):
16267 * xterm.c (x_check_font): Remove unused local.
16268 * scroll.c (CHECK_BOUNDS):
16269 * xfaces.c (cache_fache): Rename local to avoid shadowing.
16270 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
16271 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
16272 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
16273 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
16275 (debug_method_add): Use va_list and vsprintf rather than relying
16276 on undefined behavior with wrong number of arguments.
16277 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
16278 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
16279 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
16280 since we're not interested in debugging glyphs with old libraries.
16281 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
16282 GCC 4.6.0's static checking.
16284 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
16286 Integer overflow and signedness fixes (Bug#8873).

16302 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
16303 (.bitmaps_last, struct x_output.icon_bitmap):
16304 Use ptrdiff_t, not int, for bitmap indexes.
16305 (x_allocate_bitmap_record): Check for size overflow.
16306 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
16308 Use ptrdiff_t, not int, for overlay counts.
16309 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
16310 * editfns.c (overlays_around, get_pos_property):
16311 * textprop.c (get_char_property_and_overlay):
16312 * xdisp.c (next_overlay_change, note_mouse_highlight):
16313 * xfaces.c (face_at_buffer_position):
16314 * buffer.c (OVERLAY_COUNT_MAX): New macro.
16315 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
16316 (Fnext_overlay_change, Fprevious_overlay_change)
16317 (mouse_face_overlay_overlaps, Foverlays_in):
16318 Use ptrdiff_t, not int, for sizes.
16319 (overlays_at, overlays_in): Check for size-calculation overflow.
16321 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
16323 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
16324 (x_session_initialize): Do not assume string length fits in int.
16326 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
16327 This is unlikely, but can occur if DPI is outlandish.
16329 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
16330 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
16332 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
16333 * xrdb.c (magic_file_p, search_magic_path):
16334 Omit last arg SUFFIX; it was always 0. All callers changed.
16335 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
16337 * xfont.c (xfont_match): Avoid need for strlen.
16339 * xfns.c: Don't assume strlen fits in int.

16342 * xdisp.c (message_log_check_duplicate): Return intmax_t,
16343 not unsigned long, as we prefer signed integers. All callers changed.
16344 Detect integer overflow in repeat count.
16345 (message_dolog): Don't assume print length fits in 39 bytes.
16346 (display_mode_element): Don't assume strlen fits in int.
16348 * termcap.c: Don't assume sizes fit in int and never overflow.
16349 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
16350 (gobble_line): Check for size-calculation overflow.
16352 * minibuf.c (Fread_buffer):
16353 * lread.c (intern, intern_c_string):
16354 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

16367 * filelock.c: Fix some buffer overrun and integer overflow issues.
16368 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
16369 Reformulate so as not to need the command string.
16370 Invoke gzip -cd rather than gunzip, as it's more portable.
16371 (lock_info_type, lock_file_1, lock_file):
16372 Don't assume pid_t and time_t fit in unsigned long.
16373 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
16374 (current_lock_owner): Prefer signed type for sizes.
16375 Use memcpy, not strncpy, where memcpy is what is really wanted.
16376 Don't assume (via atoi) that time_t and pid_t fit in int.
16377 Check for time_t and/or pid_t out of range, e.g., via a network share.
16378 Don't alloca where an auto var works fine.
16380 * fileio.c: Fix some integer overflow issues.
16381 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
16382 Don't assume string length fits in int.
16383 (directory_file_name): Don't assume string length fits in long.
16384 (make_temp_name): Don't assume pid fits in int, or that its print
16385 length is less than 20.
16387 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
16389 * coding.c (make_subsidiaries): Don't assume string length fits in int.
16391 * callproc.c (child_setup): Rewrite to avoid two strlen calls.

16404 (Fgetenv_internal):
16405 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
16407 * lread.c (invalid_syntax): Omit length argument.
16408 All uses changed. This doesn't fix a bug, but it simplifies the
16409 code away from its former Hollerith-constant appearance, and it's
16410 one less 'int' to worry about when looking at integer-overflow issues.
16411 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
16413 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
16414 This didn't break anything, but it didn't help either.
16415 It's confusing to put a bogus integer in a place where the actual
16416 value does not matter.
16417 (LIST_END_P): Remove unused macro and its bogus comment.
16418 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
16420 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
16421 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
16423 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
16424 We prefer signed types, and the value cannot exceed the EMACS_INT
16425 range anyway (because otherwise the length would not be representable).
16426 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
16427 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
16428 This avoids a GCC warning when WIDE_EMACS_INT.
16430 * indent.c (sane_tab_width): New function.
16431 (current_column, scan_for_column, Findent_to, position_indentation)
16432 (compute_motion): Use it. This is just for clarity.
16433 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
16435 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
16437 * lisp.h (lint_assume): New macro.
16438 * composite.c (composition_gstring_put_cache):
16439 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
16441 * editfns.c, insdel.c:
16442 Omit unnecessary forward decls, to simplify future changes.
16444 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
16446 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
16448 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
16449 Use much-faster test for byte-length change.
16450 Don't assume string byte-length fits in 'int'.
16451 Check that character arg fits in 'int'.
16452 (mapcar1): Declare byte as byte, for clarity.
16454 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
16456 * fns.c (concat): Catch string overflow earlier.
16457 Do not rely on integer wraparound.
16459 * dispextern.h (struct it.overlay_strings_charpos)
16460 (struct it.selective): Now EMACS_INT, not int.
16461 * xdisp.c (forward_to_next_line_start)
16462 (back_to_previous_visible_line_start)
16463 (reseat_at_next_visible_line_start, next_element_from_buffer):
16464 Don't arbitrarily truncate the value of 'selective' to int.
16466 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
16468 * composite.c: Don't truncate sizes to 'int'.
16469 (composition_gstring_p, composition_reseat_it)
16470 (composition_adjust_point): Use EMACS_INT, not int.
16471 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
16472 not EMACS_UINT, for indexes.
16474 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
16476 * buffer.c: Include <verify.h>.
16477 (struct sortvec.priority, struct sortstr.priority):
16478 Now EMACS_INT, not int.
16479 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
16480 (struct sortstr.size, record_overlay_string)
16481 (struct sortstrlist.size, struct sortlist.used):
16482 Don't truncate size to int.
16483 (record_overlay_string): Check for size-calculation overflow.
16484 (init_buffer_once): Check at compile-time, not run-time.
16486 2011-06-22 Jim Meyering <meyering@redhat.com>
16488 Don't leak an XBM-image-sized buffer
16489 * image.c (xbm_load): Free the image buffer after using it.
16491 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
16494 * composite.c (find_automatic_composition): Omit needless 'return 0;'
16495 that Sun C diagnosed.
16496 * fns.c (secure_hash): Fix pointer signedness issue.
16497 * intervals.c (static_offset_intervals): New function.
16498 (offset_intervals): Use it.
16500 2011-06-21 Leo Liu <sdl.web@gmail.com>
16503 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
16506 * fns.c (secure_hash): Rename from crypto_hash_function and change
16507 the first arg to accept symbols.
16508 (Fsecure_hash): New primitive.
16509 (syms_of_fns): New symbols.
16511 2011-06-20 Deniz Dogan <deniz@dogan.se>
16513 * process.c (Fset_process_buffer): Clarify return value in
16516 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
16518 * dispnew.c (add_window_display_history): Use BVAR.
16520 * xdisp.c (debug_method_add): Use BVAR.
16521 (check_window_end, dump_glyph_matrix, dump_glyph)
16522 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
16524 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
16527 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
16528 check till after the cache is created in init_frame_faces.
16530 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
16532 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
16534 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
16536 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
16537 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
16538 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
16540 Improve buffer-overflow checking (Bug#8873).
16541 * fileio.c (Finsert_file_contents):
16542 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
16543 Remove the old (too-loose) buffer overflow checks.
16544 They weren't needed, since make_gap checks for buffer overflow.
16545 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
16546 The old code merely checked for Emacs fixnum overflow, and relied
16547 on undefined (wraparound) behavior. The new code avoids undefined
16548 behavior, and also checks for ptrdiff_t and/or size_t overflow.
16550 * editfns.c (Finsert_char): Don't dump core with very negative counts.
16551 Tune. Don't use wider integers than needed. Don't use alloca.
16552 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
16554 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
16556 * insdel.c, lisp.h (buffer_overflow): New function.
16557 (insert_from_buffer_1, replace_range, replace_range_2):
16558 * insdel.c (make_gap_larger):
16559 * editfns.c (Finsert_char):
16560 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
16562 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
16564 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
16566 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
16568 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
16569 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
16571 * fileio.c: Don't assume EMACS_INT fits in off_t.
16572 (emacs_lseek): New static function.
16573 (Finsert_file_contents, Fwrite_region): Use it.
16574 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
16576 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
16578 * fns.c: Don't overflow int when computing a list length.
16579 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
16580 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
16581 truncation on 64-bit hosts. Check for QUIT every
16582 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
16583 faster and is responsive enough.
16584 (Flength): Report an error instead of overflowing an integer.
16585 (Fsafe_length): Return a float if the value is not representable
16586 as a fixnum. This shouldn't happen except in contrived situations.
16587 (Fnthcdr, Fsort): Don't assume list length fits in int.
16588 (Fcopy_sequence): Don't assume vector length fits in int.
16590 * alloc.c: Check that resized vectors' lengths fit in fixnums.
16591 (header_size, word_size): New constants.
16592 (allocate_vectorlike): Don't check size overflow here.
16593 (allocate_vector): Check it here instead, since this is the only
16594 caller of allocate_vectorlike that could cause overflow.
16595 Check that the new vector's length is representable as a fixnum.
16597 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
16598 The previous code was bogus. For example, next_almost_prime (32)
16599 returned 39, which is undesirable as it is a multiple of 3; and
16600 next_almost_prime (24) returned 25, which is a multiple of 5 so
16601 why was the code bothering to check for multiples of 7?
16603 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
16605 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
16607 Variadic C functions now count arguments with ptrdiff_t.
16608 This partly undoes my 2011-03-30 change, which replaced int with size_t.
16609 Back then I didn't know that the Emacs coding style prefers signed int.
16610 Also, in the meantime I found a few more instances where arguments
16611 were being counted with int, which may truncate counts on 64-bit
16612 machines, or EMACS_INT, which may be unnecessarily wide.
16613 * lisp.h (struct Lisp_Subr.function.aMANY)
16614 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
16615 Arg counts are now ptrdiff_t, not size_t.
16616 All variadic functions and their callers changed accordingly.
16617 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
16618 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
16619 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
16620 * callint.c (Fcall_interactively): Check arg count for overflow,
16621 to avoid potential buffer overrun. Use signed char, not 'int',
16622 for 'varies' array, so that we needn't bother to check its size
16623 calculation for overflow.
16624 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
16625 * eval.c (apply_lambda):
16626 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
16627 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
16628 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
16630 * callint.c (Fcall_interactively): Don't use index var as event count.
16632 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
16633 * mem-limits.h (SIZE): Remove; no longer used.
16635 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
16637 Remove unnecessary casts.
16638 * xterm.c (x_term_init):
16639 * xfns.c (x_set_border_pixel):
16640 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
16641 These aren't needed now that we assume ANSI C.
16643 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
16644 It's more likely to cause problems (due to unsigned overflow)
16647 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
16649 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
16651 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
16653 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
16655 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
16657 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
16659 GLYPH_CODE_FACE returns EMACS_INT, not int.
16660 * dispextern.h (merge_faces):
16661 * xfaces.c (merge_faces):
16662 * xdisp.c (get_next_display_element, next_element_from_display_vector):
16663 Don't assume EMACS_INT fits in int.
16665 * character.h (CHAR_VALID_P): Remove unused parameter.
16666 * fontset.c, lisp.h, xdisp.c: All uses changed.
16668 * editfns.c (Ftranslate_region_internal): Omit redundant test.
16670 * fns.c (concat): Minor tuning based on overflow analysis.
16671 This doesn't fix any bugs. Use int to hold character, instead
16672 of constantly refetching from Emacs object. Use XFASTINT, not
16673 XINT, for value known to be a character. Don't bother comparing
16674 a single byte to 0400, as it's always less.
16676 * floatfns.c (Fexpt):
16677 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
16679 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
16682 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
16684 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
16685 Without this fix, on a 64-bit host (aset S 0 4294967386) would
16686 incorrectly succeed when S was a string, because 4294967386 was
16687 truncated before it was used.
16689 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
16690 Otherwise, an out-of-range integer could cause undefined behavior
16693 * composite.c: Use int, not EMACS_INT, for characters.
16694 (fill_gstring_body, composition_compute_stop_pos): Use int, not
16695 EMACS_INT, for values that are known to be in character range.
16696 This doesn't fix any bugs but is the usual style inside Emacs and
16697 may generate better code on 32-bit machines.
16699 Make sure a 64-bit char is never passed to ENCODE_CHAR.
16700 This is for reasons similar to the recent CHAR_STRING fix.
16701 * charset.c (Fencode_char): Check that character arg is actually
16702 a character. Pass an int to ENCODE_CHAR.
16703 * charset.h (ENCODE_CHAR): Verify that the character argument is no
16704 wider than 'int', as a compile-time check to prevent future regressions
16707 * character.c (char_string): Remove unnecessary casts.
16709 Make sure a 64-bit char is never passed to CHAR_STRING.
16710 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
16711 by silently ignoring the top 32 bits, allowing some values
16712 that were far too large to be valid characters.
16713 * character.h: Include <verify.h>.
16714 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
16715 arguments are no wider than unsigned, as a compile-time check
16716 to prevent future regressions in this area.
16718 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
16719 (Fsubst_char_in_region):
16721 * xdisp.c (decode_mode_spec_coding):
16722 Adjust to CHAR_STRING's new requirement.
16723 * editfns.c (Finsert_char, Fsubst_char_in_region):
16724 * fns.c (concat): Check that character args are actually
16725 characters. Without this test, these functions did the wrong
16726 thing with wildly out-of-range values on 64-bit hosts.
16728 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
16729 These casts should not be needed on 32-bit hosts, either.
16730 * keyboard.c (read_char):
16731 * lread.c (Fload): Remove casts to unsigned.
16733 * lisp.h (UNSIGNED_CMP): New macro.
16734 This fixes comparison bugs on 64-bit hosts.
16735 (ASCII_CHAR_P): Use it.
16736 * casefiddle.c (casify_object):
16737 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
16738 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
16739 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
16740 * dispextern.h (FACE_FROM_ID):
16741 * keyboard.c (read_char): Use UNSIGNED_CMP.
16743 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
16744 not to EMACS_INT, to avoid GCC warning.
16746 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
16748 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
16749 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
16750 isn't needed on 32-bit machines.
16752 * buffer.c (Fgenerate_new_buffer_name):
16753 Use EMACS_INT for count, not int.
16754 (advance_to_char_boundary): Return EMACS_INT, not int.
16756 * data.c (Qcompiled_function): Now static.
16758 * window.c (window_body_lines): Now static.
16760 * image.c (gif_load): Rename local to avoid shadowing.
16762 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
16763 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
16764 * alloc.c (make_save_value): Integer argument is now of type
16765 ptrdiff_t, not int.
16766 (mark_object): Use ptrdiff_t, not int.
16767 * lisp.h (pD): New macro.
16768 * print.c (print_object): Use it.
16770 * alloc.c: Use EMACS_INT, not int, to count objects.
16771 (total_conses, total_markers, total_symbols, total_vector_size)
16772 (total_free_conses, total_free_markers, total_free_symbols)
16773 (total_free_floats, total_floats, total_free_intervals)
16774 (total_intervals, total_strings, total_free_strings):
16775 Now EMACS_INT, not int. All uses changed.
16776 (Fgarbage_collect): Compute overall total using a double, so that
16777 integer overflow is less likely to be a problem. Check for overflow
16778 when converting back to an integer.
16779 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
16780 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
16781 These were 'int' variables that could overflow on 64-bit hosts;
16782 they were never used, so remove them instead of repairing them.
16783 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
16784 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
16785 Previously, this ceilinged at INT_MAX, but that doesn't work on
16787 (allocate_pseudovector): Don't use EMACS_INT when int would do.
16789 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
16790 (allocate_vectorlike): Check for ptrdiff_t overflow.
16791 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
16792 when a (possibly-narrower) signed value would do just as well.
16793 We prefer using signed arithmetic, to avoid comparison confusion.
16795 * alloc.c: Catch some string size overflows that we were missing.
16796 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
16797 for convenience in STRING_BYTES_MAX.
16798 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
16799 The definition here is exact; the one in lisp.h was approximate.
16800 (allocate_string_data): Check for string overflow. This catches
16801 some instances we weren't catching before. Also, it catches
16802 size_t overflow on (unusual) hosts where SIZE_MAX <= min
16803 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
16804 and ptrdiff_t and EMACS_INT are both 64 bits.
16806 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
16807 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
16808 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
16810 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
16812 * alloc.c (Fmake_string): Check for out-of-range init.
16814 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
16816 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
16818 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
16820 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
16821 xg_get_default_scrollbar_width.
16823 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
16824 (int_gtk_range_get_value): Move to the scroll bar part of the file.
16825 (style_changed_cb): Call update_theme_scrollbar_width and call
16826 x_set_scroll_bar_default_width and xg_frame_set_char_size for
16827 all frames (Bug#8505).
16828 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
16829 Call gtk_window_set_resizable if HAVE_GTK3.
16830 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
16831 and height if HAVE_GTK3 (Bug#8505).
16832 (scroll_bar_width_for_theme): New variable.
16833 (update_theme_scrollbar_width): New function.
16834 (xg_get_default_scrollbar_width): Move code to
16835 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
16836 (xg_initialize): Call update_theme_scrollbar_width.
16838 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
16840 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
16842 2011-06-12 Martin Rudalics <rudalics@gmx.at>
16844 * frame.c (make_frame): Call other_buffer_safely instead of
16847 * window.c (temp_output_buffer_show): Call display_buffer with
16848 second argument Vtemp_buffer_show_specifiers and reset latter
16849 immediately after the call.
16850 (Vtemp_buffer_show_specifiers): New variable.
16851 (auto_window_vscroll_p, next_screen_context_lines)
16852 (Vscroll_preserve_screen_position): Remove leading asterisks from
16855 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
16857 Fix minor problems found by GCC 4.6.0 static checking.
16858 * buffer.c (Qclone_number): Remove for now, as it's unused.
16859 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
16860 (record_buffer): Remove unused local.
16861 * frame.c (other_visible_frames, frame_buffer_list): Now static.
16862 (set_frame_buffer_list): Remove; unused.
16863 * frame.h (other_visible_frames): Remove decl.
16864 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
16865 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
16866 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
16868 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
16869 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
16870 Define only if HAVE_GPM.
16871 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
16872 (update_hints_inhibit): Remove; never set. All uses removed.
16873 * widgetprv.h (emacsFrameClassRec): Remove decl.
16874 * window.c (delete_deletable_window): Now returns void, since it
16875 wasn't returning anything.
16876 (compare_window_configurations): Remove unused locals.
16877 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
16878 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
16879 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
16880 the same widths as pointers. This follows up on the 2011-05-06 patch.
16881 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
16882 * xterm.h: Likewise.
16883 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
16885 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
16887 * makefile.w32-in: Update dependencies.
16888 (LISP_H): Add lib/intprops.h.
16890 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
16892 * image.c (gif_load): Add animation frame delay to the metadata.
16893 (syms_of_image): Use DEFSYM. New symbol `delay'.
16895 2011-06-11 Martin Rudalics <rudalics@gmx.at>
16897 * window.c (delete_deletable_window): Re-add.
16898 (Fset_window_configuration): Rewrite to handle dead buffers and
16899 consequently deletable windows.
16900 (window_tree, Fwindow_tree): Remove. Supply functionality in
16902 (compare_window_configurations): Simplify code.
16904 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
16906 * image.c (imagemagick_load_image): Fix type mismatch.
16907 (Fimagemagick_types): Likewise.
16909 * window.h (replace_buffer_in_windows): Declare.
16911 2011-06-11 Martin Rudalics <rudalics@gmx.at>
16913 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
16914 Qclone_number. Remove external declaration of Qdelete_window.
16915 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
16917 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
16918 Run Qbuffer_list_update_hook if allowed.
16919 (Fother_buffer): Rewrite doc-string. Major rewrite for new
16920 buffer list implementation.
16921 (other_buffer_safely): New function.
16922 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
16923 calls to replace_buffer_in_windows and
16924 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
16926 (record_buffer): Inhibit quitting and rewrite using quittable
16927 functions. Run Qbuffer_list_update_hook if allowed.
16928 (Frecord_buffer, Funrecord_buffer): New functions.
16929 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
16930 Move switch-to-buffer to window.el.
16931 (bury-buffer): Move to window.el.
16932 (Vbuffer_list_update_hook): New variable.
16934 * lisp.h (other_buffer_safely): Add prototype in buffer.c
16937 * window.h (resize_frame_windows): Move up in code.
16938 (Fwindow_frame): Remove EXFUN.

17388 bidirectional text is supported only in multibyte buffers.
17389 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
17390 it to initialize the frame_window_p member of struct bidi_it.
17391 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
17392 (bidi_resolve_explicit, bidi_resolve_weak)
17393 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
17394 bidi_it->nchars is non-positive.
17395 (bidi_level_of_next_char): Don't try to lookup the cache for the
17396 next/previous character if nothing is cached there yet, or if we
17397 were just reseat()'ed to a new position.
17399 * xdisp.c (set_cursor_from_row): Set start and stop points
17400 according to the row's direction when priming the loop that looks
17401 for the glyph on which to display cursor.
17402 (single_display_spec_intangible_p): Function deleted.
17403 (display_prop_intangible_p): Reimplement to call
17404 handle_display_spec instead of single_display_spec_intangible_p.
17405 Accept 3 additional arguments needed by handle_display_spec.
17406 This fixes incorrect cursor motion across display property with complex
17407 values: lists, `(when COND...)' forms, etc.
17408 (single_display_spec_string_p): Support property values that are
17409 lists with the argument STRING its top-level element.
17410 (display_prop_string_p): Fix the condition for processing a
17411 property that is a list to be consistent with handle_display_spec.
17412 (handle_display_spec): New function, refactored from the
17413 last portion of handle_display_prop.
17414 (compute_display_string_pos): Accept additional argument
17415 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
17416 value of a `display' property is a "replacing spec".
17417 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
17418 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
17419 the display property, but just return a value indicating whether
17420 the display property will replace the characters it covers.
17421 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
17422 frame_window_p members of struct bidi_it.
17423 (compute_display_string_pos, compute_display_string_end):
17425 (push_it): Accept second argument POSITION, where pop_it should
17426 jump to continue iteration.
17427 (reseat_1): Initialize bidi_it.disp_pos.
17429 * keyboard.c (adjust_point_for_property): Adjust the call to
17430 display_prop_intangible_p to its new signature.
17432 * dispextern.h (struct bidi_it): New member frame_window_p.
17433 (bidi_init_it): Update prototypes.
17434 (display_prop_intangible_p): Update prototype.
17435 (compute_display_string_pos, compute_display_string_end):
17436 Declare prototypes.
17437 (struct bidi_it): New members nchars and disp_pos. ch_len is now
17440 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
17442 Malloc failure behavior now depends on size of allocation.
17443 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
17444 * lisp.h: Change signatures accordingly.
17445 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
17446 All callers changed. (Bug#8762)
17448 * gnutls.c: Use Emacs's memory allocators.
17449 Without this change, the gnutls library would invoke malloc etc.
17450 directly, which causes problems on non-SYNC_INPUT hosts, and which
17451 runs afoul of improving memory_full behavior. (Bug#8761)
17452 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
17453 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
17454 xfree instead of the default malloc, realloc, free.
17455 (Fgnutls_boot): No need to check for memory allocation failure,
17456 since xmalloc does that for us.
17458 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
17459 * category.c (hash_get_category_set):
17460 * ccl.c (ccl_driver):
17461 * charset.c (Fdefine_charset_internal):
17462 * charset.h (struct charset.hash_index):

17464 (composition_gstring_put_cache):
17465 * composite.h (struct composition.hash_index):
17466 * dispextern.h (struct image.hash):
17467 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
17468 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
17469 (hashfn_equal, hashfn_user_defined, make_hash_table)
17470 (maybe_resize_hash_table, hash_lookup, hash_put)
17471 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
17472 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
17473 (Fsxhash, Fgethash, Fputhash, Fmaphash):
17474 * image.c (make_image, search_image_cache, lookup_image)
17475 (xpm_put_color_table_h):
17476 * lisp.h (struct Lisp_Hash_Table):
17477 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
17478 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
17479 for hashes and hash indexes, instead of 'unsigned' and 'int'.
17480 * alloc.c (allocate_vectorlike):
17481 Check for overflow in vector size calculations.
17482 * ccl.c (ccl_driver):
17483 Check for overflow when converting EMACS_INT to int.
17484 * fns.c, image.c: Remove unnecessary static decls that would otherwise
17485 need to be updated by these changes.
17486 * fns.c (make_hash_table, maybe_resize_hash_table):
17487 Check for integer overflow with large hash tables.
17488 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
17489 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
17490 (SXHASH_REDUCE): New macro.
17491 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
17492 Use it instead of discarding useful hash info with large hash values.
17493 (sxhash_float): New function.
17494 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
17495 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
17496 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
17497 Rewrite to use FIXNUM_BITS, as this simplifies things.
17498 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
17499 Adjust signatures to match updated version of code.
17500 (consing_since_gc): Now EMACS_INT, since a single hash table can
17501 use more than INT_MAX bytes.
17503 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
17505 Make it possible to build with GCC-4.6+ -O2 -flto.
17507 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
17509 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
17511 * minibuf.c (get_minibuffer, read_minibuf_unwind):
17512 Call minibuffer-inactive-mode.
17514 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
17516 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
17517 Update dependencies.
17519 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17521 * data.c (init_data): Remove code for UTS, this system is not
17524 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17526 Don't force ./temacs to start in terminal mode.
17528 * frame.c (make_initial_frame): Initialize faces in all cases, not
17529 only when CANNOT_DUMP is defined.
17530 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
17532 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17534 * dispnew.c (add_window_display_history): Use const for the string
17535 pointer. Remove declaration, not needed.
17537 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
17539 Use 'inline', not 'INLINE'.
17540 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
17541 * alloc.c, fontset.c (INLINE): Remove.
17542 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
17543 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
17544 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
17545 * gmalloc.c (register_heapinfo): Use inline unconditionally.
17546 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
17548 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17550 Make it possible to run ./temacs.
17552 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
17553 syms_of_callproc does the same thing. Remove test for
17554 "initialized", do it in the caller.
17555 * emacs.c (main): Avoid calling set_initial_environment when dumping.
17557 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
17559 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
17560 (read_minibuf): Use get_minibuffer.
17561 (syms_of_minibuf): Use DEFSYM.
17562 (Qmetadata): New var.
17563 * data.c (Qbuffer): Don't make it static.
17564 (syms_of_data): Use DEFSYM.
17566 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
17568 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
17569 (CCL_CODE_MIN): New macro.
17571 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
17573 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
17575 * eval.c (Qdebug): Now static.
17576 * lisp.h (Qdebug): Remove decl. This reverts a part of the
17577 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
17578 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
17580 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
17582 * image.c: Various fixes to ImageMagick code comments.
17583 (Fimagemagick_types): Doc fix.
17585 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
17587 Minor fixes prompted by GCC 4.6.0 warnings.
17589 * xselect.c (converted_selections, conversion_fail_tag): Now static.
17591 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
17592 (x_clipboard_manager_save_all): Move extern decl to ...
17593 * xterm.h: ... here, so that it can be checked for consistency.
17595 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
17597 * xselect.c (x_clipboard_manager_save_frame)
17598 (x_clipboard_manager_save_all): New functions.
17599 (Fx_clipboard_manager_save): Lisp function deleted.
17601 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
17602 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
17604 * xterm.h: Update prototype.
17606 2011-05-28 William Xu <william.xwl@gmail.com>
17608 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
17609 exiting (Bug#8239).
17611 2011-05-28 Jim Meyering <meyering@redhat.com>
17613 Avoid a sign-extension bug in crypto_hash_function.
17614 * fns.c (to_uchar): Define.
17615 (crypto_hash_function): Use it to convert some newly-signed
17616 variables to unsigned, to avoid sign-extension bugs. For example,
17617 without this change, (md5 "truc") would evaluate to
17618 45723a2aff78ff4fff7fff1114760e62 rather than the expected
17619 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
17620 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
17622 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17624 Integer overflow fixes.
17626 * dbusbind.c: Serial number integer overflow fixes.
17627 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
17628 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
17629 to hold a serial number that is too large for a fixnum.
17630 (Fdbus_method_return_internal, Fdbus_method_error_internal):
17631 Check for serial numbers out of range. Decode any serial number
17632 that was so large that it became a float. (Bug#8722)
17634 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
17635 (Fdbus_call_method, Fdbus_call_method_asynchronously):
17636 Use XFASTINT rather than XUINT when numbers are nonnegative.
17637 (xd_append_arg, Fdbus_method_return_internal):
17638 (Fdbus_method_error_internal): Likewise. Also, for unsigned
17639 arguments, check that Lisp number is nonnegative, rather than
17640 silently wrapping negative numbers around. (Bug#8722)
17641 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
17644 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
17646 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
17648 ccl: Add integer overflow checks.
17649 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
17650 (IN_INT_RANGE): New macros.
17651 (ccl_driver): Use them to check for integer overflow when
17652 decoding a CCL program. Many of the new checks are whether XINT (x)
17653 fits in int; it doesn't always, on 64-bit hosts. The new version
17654 doesn't catch all possible integer overflows, but it's an
17655 improvement. (Bug#8719)
17657 * alloc.c (make_event_array): Use XINT, not XUINT.
17658 There's no need for unsigned here.
17660 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
17661 This follows up to the 2011-05-06 change that substituted uintptr_t
17662 for EMACS_INT. This case wasn't caught back then.
17664 Rework Fformat to avoid integer overflow issues.
17665 * editfns.c: Include <float.h> unconditionally, as it's everywhere
17666 now (part of C89). Include <verify.h>.
17667 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
17668 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
17669 (Fformat): Avoid the prepass trying to compute sizes; it was only
17670 approximate and thus did not catch overflow reliably. Instead, walk
17671 through the format just once, formatting and computing sizes as we go,
17672 checking for integer overflow at every step, and allocating a larger
17673 buffer as needed. Keep track separately whether the format is
17674 multibyte. Keep only the most-recently calculated precision, rather
17675 than them all. Record whether each argument has been converted to
17676 string. Use EMACS_INT, not int, for byte and char and arg counts.
17677 Support field widths and precisions larger than INT_MAX. Avoid
17678 sprintf's undefined behavior with conversion specifications such as %#d
17679 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
17680 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
17681 formatting out-of-range floating point numbers with int
17682 formats. (Bug#8668)
17684 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
17686 * data.c: Avoid integer truncation in expressions involving floats.
17687 * data.c: Include <intprops.h>.
17688 (arith_driver): When there's an integer overflow in an expression
17689 involving floating point, convert the integers to floating point
17690 so that the resulting value does not suffer from catastrophic
17691 integer truncation. For example, on a 64-bit host (* 4
17692 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
17693 Do not rely on undefined behavior after integer overflow.
17695 merge count_size_as_multibyte, parse_str_to_multibyte
17696 * character.c, character.h (count_size_as_multibyte):
17697 Rename from parse_str_to_multibyte; all uses changed.
17698 Check for integer overflow.
17699 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
17700 since it's now a duplicate of the other. This is more of
17701 a character than a buffer op, so better that it's in character.c.
17702 * fns.c, print.c: Adjust to above changes.
17704 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
17706 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
17708 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17710 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17711 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
17712 (x_clipboard_manager_save): Now static.
17713 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
17715 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17716 (crypto_hash_function): Now static.
17717 Fix pointer signedness problems. Avoid unnecessary initializations.
17719 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
17721 * termhooks.h (Vselection_alist): Make it terminal-local.
17723 * terminal.c (create_terminal): Initialize it.
17725 * xselect.c: Support for clipboard managers.
17726 (Vselection_alist): Move to termhooks.h as terminal-local var.
17727 (LOCAL_SELECTION): New macro.
17728 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
17729 (symbol_to_x_atom): Remove gratuitous arg.
17730 (x_handle_selection_request, lisp_data_to_selection_data)
17731 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
17732 (x_own_selection, x_get_local_selection, x_convert_selection):
17733 New arg, specifying work frame. Use terminal-local Vselection_alist.
17734 (some_frame_on_display): Delete unused function.
17735 (Fx_own_selection_internal, Fx_get_selection_internal)
17736 (Fx_disown_selection_internal, Fx_selection_owner_p)
17737 (Fx_selection_exists_p): New optional frame arg.
17738 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
17739 (x_handle_selection_clear): Don't treat other terminals with the
17740 same keyboard specially. Use the terminal-local Vselection_alist.
17741 (x_clear_frame_selections): Use Frun_hook_with_args.
17743 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
17745 * xterm.h: Add support for those atoms.
17747 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
17749 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
17750 (converted_selections, conversion_fail_tag): New global variables.
17751 (x_selection_request_lisp_error): Free the above.
17752 (x_get_local_selection): Remove unnecessary code.
17753 (x_reply_selection_request): Args changed; handle arbitrary array
17754 of converted selections stored in converted_selections.
17755 Separate the XChangeProperty and SelectionNotify steps.
17756 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
17757 (x_convert_selection): New function.
17758 (x_handle_selection_event): Simplify.
17759 (x_get_foreign_selection): Don't ignore incoming requests while
17760 waiting for an answer; this will fail when we implement
17761 SAVE_TARGETS, and seems unnecessary anyway.
17762 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
17763 (Vx_sent_selection_functions): Doc fix.
17765 2011-05-26 Leo Liu <sdl.web@gmail.com>
17767 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
17769 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17771 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
17773 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
17774 for fringe update if it has periodic bitmap.
17775 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
17776 and fringe_bitmap_periodic_p.
17778 * fringe.c (get_fringe_bitmap_data): New function.
17779 (draw_fringe_bitmap_1, update_window_fringes): Use it.
17780 (update_window_fringes): Record periodicity of fringe bitmap in glyph
17781 row. Mark glyph row for fringe update if periodicity changed.
17783 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
17784 for fringe update unless it has periodic bitmap.
17786 2011-05-25 Kenichi Handa <handa@m17n.org>
17788 * xdisp.c (get_next_display_element): Set correct it->face_id for
17789 a static composition.
17791 2011-05-24 Leo Liu <sdl.web@gmail.com>

17797 (Fmd5): Use crypto_hash_function.
17798 (syms_of_fns): Add Ssha1.
17800 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
17802 * gnutls.c: Remove unused macros.
17803 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
17804 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
17805 Remove macros that are defined and never used.
17806 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
17808 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17810 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
17811 (Fx_get_selection_internal): Minor cleanup.
17812 (Fx_own_selection_internal): Rename arguments for consistency with
17815 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
17817 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
17819 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17821 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
17823 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17825 * dispnew.c (scrolling_window): Don't exclude the case that the
17826 last enabled row in the desired matrix touches the bottom boundary.
17828 2011-05-21 Glenn Morris <rgm@gnu.org>
17830 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
17831 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
17832 and add some more files.
17834 2011-05-20 Eli Zaretskii <eliz@gnu.org>
17836 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
17837 report_file_error introduced by the change from 2011-05-07.
17839 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
17841 * systime.h (Time): Define only if emacs is defined.
17842 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
17843 where the include path doesn't have X11/X.h by default. See
17844 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
17846 2011-05-20 Kenichi Handa <handa@m17n.org>
17848 * composite.c (find_automatic_composition): Fix previous change.
17850 2011-05-20 Glenn Morris <rgm@gnu.org>
17852 * lisp.mk: New file, split from Makefile.in.
17853 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
17854 (shortlisp): Remove.
17855 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
17857 2011-05-19 Glenn Morris <rgm@gnu.org>
17859 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
17860 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
17861 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
17862 (lisp): Set the order to that of loadup.el.
17863 (shortlisp): Make it a copy of $lisp.
17864 (SOME_MACHINE_LISP): Remove.
17865 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
17866 Use just $shortlisp, not $SOME_MACHINE_LISP too.
17868 2011-05-18 Kenichi Handa <handa@m17n.org>
17870 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
17871 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
17872 (find_automatic_composition): Mostly rewrite for efficiency.
17874 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
17876 * makefile.w32-in: Update dependencies.
17878 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
17880 * menu.c: Include limits.h (fixes the MS-Windows build broken by
17881 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
17883 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
17885 Fix some integer overflow issues, such as string length overflow.
17887 * insdel.c (count_size_as_multibyte): Check for string overflow.
17889 * character.c (lisp_string_width): Check for string overflow.
17890 Use EMACS_INT, not int, for string indexes and lengths; in
17891 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
17892 the resulting string length overflows an EMACS_INT; instead,
17893 report a string overflow if no precision given. When checking for
17894 precision exhaustion, use a check that cannot possibly have
17895 integer overflow. (Bug#8675)
17896 * character.h (lisp_string_width): Adjust to new signature.
17898 * alloc.c (string_overflow): New function.
17899 (Fmake_string): Use it. This doesn't change behavior, but saves
17900 a few bytes and will simplify future changes.
17901 * character.c (string_escape_byte8): Likewise.
17902 * lisp.h (string_overflow): New decl.
17904 Fixups, following up to the user-interface timestamp change.
17905 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
17906 for UI timestamps, instead of unsigned long.
17907 * msdos.c (mouse_get_pos): Likewise.
17908 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
17909 * w32gui.h (Time): Define by including "systime.h" rather than by
17910 declaring it ourselves. (Bug#8664)
17912 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
17913 * image.c (clear_image_cache): Likewise.
17915 * term.c (term_mouse_position): Don't assume time_t wraparound.
17917 Be more systematic about user-interface timestamps.
17918 Before, the code sometimes used 'Time', sometimes 'unsigned long',
17919 and sometimes 'EMACS_UINT', to represent these timestamps.
17920 This change causes it to use 'Time' uniformly, as that's what X uses.
17921 This makes the code easier to follow, and makes it easier to catch
17922 integer overflow bugs such as Bug#8664.
17923 * frame.c (Fmouse_position, Fmouse_pixel_position):
17924 Use Time, not unsigned long, for user-interface timestamps.
17925 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
17926 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
17927 * keyboard.h (last_event_timestamp): Likewise.
17928 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
17929 * menu.h (xmenu_show): Likewise.
17930 * term.c (term_mouse_position): Likewise.
17931 * termhooks.h (struct input_event.timestamp): Likewise.
17932 (struct terminal.mouse_position_hook): Likewise.
17933 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
17934 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
17935 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
17936 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
17937 what it was before.
17938 * menu.h, termhooks.h: Include "systime.h", for Time.
17940 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
17941 Don't assume that the difference between two unsigned long values
17942 can fit into an integer. At this point, we know button_down_time
17943 <= event->timestamp, so the difference must be nonnegative, so
17944 there's no need to cast the result if double-click-time is
17945 nonnegative, as it should be; check that it's nonnegative, just in
17946 case. This bug is triggered when events are more than 2**31 ms
17947 apart (about 25 days). (Bug#8664)
17949 * xselect.c (last_event_timestamp): Remove duplicate decl.
17950 (x_own_selection): Remove needless cast to unsigned long.
17952 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
17953 that always fit in int. Use a sentinel instead of a counter, to
17954 avoid a temp and to allay GCC's concerns about possible int overflow.
17955 * frame.h (struct frame): Use int for menu_bar_items_used
17956 instead of EMACS_INT, since it always fits in int.
17958 * menu.c (grow_menu_items): Check for int overflow.
17960 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
17962 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
17963 Before, the code was not consistent. These values cannot exceed
17964 2**31 - 1 so there's no need to make them unsigned.
17965 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
17966 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
17967 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
17969 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
17971 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
17972 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
17973 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
17974 presumably because the widths might not match.
17976 * window.c (size_window): Avoid needless test at loop start.
17978 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
17980 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
17982 2011-05-12 Drew Adams <drew.adams@oracle.com>
17984 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
17986 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17988 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
17989 `width' to `bar_area_x' and `bar_area_width', respectively.
17990 (x_scroll_run): Take account of fringe background extension.
17992 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
17993 Rename local vars `left' and `width' to `bar_area_x' and
17994 `bar_area_width', respectively.
17995 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
17996 background extension.
17998 2011-05-10 Jim Meyering <meyering@redhat.com>
18000 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
18002 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
18004 * image.c (Finit_image_library): Return t for built-in image types,
18005 like pbm and xbm. (Bug#8640)
18007 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
18009 * w32menu.c (set_frame_menubar): Fix submenu allocation.
18011 2011-05-07 Eli Zaretskii <eliz@gnu.org>
18013 * w32console.c (Fset_screen_color): Doc fix.
18014 (Fget_screen_color): New function.
18015 (syms_of_ntterm): Defsubr it.
18017 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
18018 unlink the temporary file if Fcall_process didn't create it in the
18020 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
18021 child process will be redirected to a file specified with `:file'.
18022 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
18023 cue to call_process_cleanup not to close that handle.
18025 2011-05-07 Ben Key <bkey76@gmail.com>
18027 * makefile.w32-in: The bootstrap-temacs rule now makes use of
18028 one of two shell specific rules, either bootstrap-temacs-CMD or
18029 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
18030 to the previous implementation of the bootstrap-temacs rule.
18031 The bootstrap-temacs-CMD rule is similar to the previous
18032 implementation of the bootstrap-temacs rule except that it
18033 makes use of the ESC_CFLAGS variable instead of the CFLAGS
18036 These changes, along with some changes to nt/configure.bat,
18037 nt/gmake.defs, and nt/nmake.defs, are required to extend my
18038 earlier fix to add support for --cflags and --ldflags options
18039 that include quotes so that it works whether make uses cmd or
18042 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
18044 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
18045 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
18047 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
18048 a string. Handle both cases.
18049 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
18050 (Fdbus_register_method): Use Qinvalid_function.
18052 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18054 * makefile.w32-in: Update dependencies.
18055 (LISP_H): Add inttypes.h and stdin.h.
18056 (PROCESS_H): Add unistd.h.
18058 2011-05-06 Eli Zaretskii <eliz@gnu.org>
18060 * lread.c: Include limits.h (fixes the MS-Windows build broken by
18061 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
18063 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
18065 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
18067 * term.c (vfatal): Remove stray call to va_end.
18068 It's not needed and the C Standard doesn't allow it here anyway.
18070 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
18071 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
18073 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
18076 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
18078 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
18080 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
18082 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
18084 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
18086 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
18087 * charset.c (Fdefine_charset_internal): Don't initialize
18088 charset.code_space[15]. The value was garbage, on hosts with
18089 32-bit int (Bug#8600).
18091 * lread.c (read_integer): Be more consistent with string-to-number.
18092 Use string_to_number to do the actual conversion; this avoids
18093 rounding errors and fixes some other screwups. Without this fix,
18094 for example, #x1fffffffffffffff was misread as -2305843009213693952.
18095 (digit_to_number): Move earlier, for benefit of read_integer.
18096 Return -1 if the digit is out of range for the base, -2 if it is
18097 not a digit in any supported base. (Bug#8602)
18099 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
18101 * dispnew.c (scrolling_window): Return 1 if we scrolled,
18102 to match comment at start of function. This also removes a
18103 GCC warning about overflow in a 32+64-bit port.
18105 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
18107 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
18108 Reported by Stefan Monnier in
18109 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
18110 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18111 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
18113 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
18114 (EMACS_UINTPTR): Likewise, with uintptr_t.
18116 * lisp.h: Prefer 64-bit EMACS_INT if available.
18117 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
18118 on 32-bit hosts that have 64-bit int, so that they can access
18120 However, temporarily disable this change unless the temporary
18121 symbol WIDE_EMACS_INT is defined.
18123 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
18125 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
18126 This removes an assumption that EMACS_INT and long are the same
18127 width as pointers. The assumption is true for Emacs porting targets
18128 now, but we want to make other targets possible.
18129 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
18130 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
18131 In the rest of the code, change types of integers that hold casted
18132 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
18133 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
18134 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
18135 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
18136 No need to cast type when ORing.
18137 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
18138 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
18139 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
18140 assume EMACS_INT is the same width as char *.
18141 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
18142 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
18143 Remove no-longer-needed casts.
18144 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
18145 (xg_tool_bar_help_callback, xg_make_tool_item):
18146 Use EMACS_INTPTR to hold an integer
18147 that will be cast to void *; this can avoid a GCC warning
18148 if EMACS_INT is not the same width as void *.
18149 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
18150 * xdisp.c (display_echo_area_1, resize_mini_window_1):
18151 (current_message_1, set_message_1):
18152 Use a local to convert to proper width without a cast.
18153 * xmenu.c (dialog_selection_callback): Likewise.
18155 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
18156 Also, don't assume VALBITS / RAND_BITS is less than 5,
18157 and don't rely on undefined behavior when shifting a 1 left into
18159 * lisp.h (get_random): Change signature to match.
18161 * lread.c (hash_string): Use size_t, not int, for hash computation.
18162 Normally we prefer signed values; but hashing is special, because
18163 it's better to use unsigned division on hash table sizes so that
18164 the remainder is nonnegative. Also, size_t is the natural width
18165 for hashing into memory. The previous code used 'int', which doesn't
18166 retain enough info to hash well into very large tables.
18167 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
18169 * dbusbind.c: Don't possibly lose pointer info when converting.
18170 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18171 Use XPNTR rather than XHASH, so that the high-order bits of
18172 the pointer aren't lost when converting through void *.
18174 * eval.c (Fautoload): Don't double-shift a pointer.
18176 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
18178 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18180 * gnutls.c (DEF_GNUTLS_FN):
18181 * image.c (DEF_IMGLIB_FN): Make function pointers static.
18183 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
18185 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
18188 2011-05-05 Eli Zaretskii <eliz@gnu.org>
18190 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
18191 New version that can reserve upto 2GB of heap space.
18193 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
18195 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
18197 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
18199 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
18200 `gnutls_certificate_set_x509_key_file'.
18202 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
18204 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
18205 Update dependencies.
18207 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18209 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
18210 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
18211 Remove unused parameter `fildes'.
18212 * process.c (read_process_output, send_process): Don't pass it.
18214 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18216 Fix previous change: the library cache is defined in w32.c.
18217 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
18218 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
18220 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18222 Implement dynamic loading of GnuTLS on Windows.
18224 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
18225 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
18226 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18229 * gnutls.c (Qgnutls_dll): Define.
18230 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
18231 (gnutls_*): Declare function pointers.
18232 (init_gnutls_functions): New function to initialize function pointers.
18233 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
18234 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
18235 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18236 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
18237 (emacs_gnutls_write, emacs_gnutls_read)

18259 * process.c: Include lisp.h before w32.h, not after.
18260 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
18261 instead of gnutls_record_check_pending.

18313 rather than `XVECTOR (FOO)->size'.
18315 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
18316 inttypes.h, as a gnulib replacement is used if it not available in

18331 charbuf for the composition carryover bytes.
18333 2011-04-21 Eli Zaretskii <eliz@gnu.org>

18336 aborting when %lld or %lll format is passed.
18337 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
18338 %llo or %llx format is passed. (Bug#8545)
18340 * window.c (window_scroll_line_based): Use a marker instead of
18341 simple variables to record original value of point. (Bug#7952)
18343 * doprnt.c (doprnt): Fix the case where a multibyte sequence
18344 produced by %s or %c overflows available buffer space. (Bug#8545)
18346 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
18348 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
18349 (SIZE_MAX): Move defn after all includes, as they might #define it.
18351 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18353 * w32.c (init_environment): Warn about defaulting HOME to C:\.
18355 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18357 * keyboard.c (Qdelayed_warnings_hook): Define.
18358 (command_loop_1): Run `delayed-warnings-hook'
18359 if Vdelayed_warnings_list is non-nil.
18360 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
18361 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
18363 2011-04-28 Eli Zaretskii <eliz@gnu.org>
18365 * doprnt.c (doprnt): Don't return value smaller than the buffer
18366 size if the message was truncated. (Bug#8545).
18368 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18370 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

18377 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
18379 * makefile.w32-in: Update dependencies.
18381 2011-04-27 Eli Zaretskii <eliz@gnu.org>
18383 Improve `doprnt' and its usage. (Bug#8545)
18384 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
18385 `format_end'. Remove support for %l as a conversion specifier.
18386 Don't use xrealloc. Improve diagnostics when the %l size modifier
18387 is used. Update the commentary.
18389 * eval.c (verror): Simplify calculation of size_t.
18391 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
18394 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
18396 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
18399 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18401 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
18402 This makes this file independent of the recent pseudovector change.
18404 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
18406 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
18408 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
18409 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
18410 Remove unused local.
18411 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
18413 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
18414 GCC 4.6.0 optimizes based on type-based alias analysis.
18415 For example, if b is of type struct buffer * and v of type struct
18416 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
18417 != &v->size, and therefore "v->size = 1; b->size = 2; return
18418 v->size;" must therefore return 1. This assumption is incorrect
18419 for Emacs, since it type-puns struct Lisp_Vector * with many other
18420 types. To fix this problem, this patch adds a new type struct
18421 vectorlike_header that documents the constraints on layout of vectors
18422 and pseudovectors, and helps optimizing compilers not get fooled
18423 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
18424 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
18425 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
18427 (XSETPVECTYPE): Rewrite in terms of new macro.
18428 (XSETPVECTYPESIZE): New macro, specifying both type and size.
18429 This is a bit clearer, and further avoids the possibility of
18430 undesirable aliasing.
18431 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
18432 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
18433 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
18434 since Lisp_Subr is a special case (no "next" field).
18435 (ASIZE): Now uses header.size rather than size.
18436 All previous uses of XVECTOR (foo)->size replaced to use this macro,
18437 to avoid the hassle of writing XVECTOR (foo)->header.size.
18438 (struct vectorlike_header): New type.
18439 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
18440 object, to help avoid aliasing.
18441 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
18442 (SUBRP): Likewise, since Lisp_Subr is a special case.
18443 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
18444 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
18445 (struct Lisp_Hash_Table): Combine first two members into a single
18446 struct vectorlike_header member. All uses of "size" and "next" members
18447 changed to be "header.size" and "header.next".
18448 * buffer.h (struct buffer): Likewise.
18449 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
18450 * frame.h (struct frame): Likewise.
18451 * process.h (struct Lisp_Process): Likewise.
18452 * termhooks.h (struct terminal): Likewise.
18453 * window.c (struct save_window_data, struct saved_window): Likewise.
18454 * window.h (struct window): Likewise.
18455 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
18456 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
18457 * buffer.c (init_buffer_once): Likewise.
18458 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
18460 * process.c (Fformat_network_address): Use local var for size,
18463 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
18465 Make the Lisp reader and string-to-float more consistent (Bug#8525)
18466 * data.c (atof): Remove decl; no longer used or needed.
18467 (digit_to_number): Move to lread.c.
18468 (Fstring_to_number): Use new string_to_number function, to be
18469 consistent with how the Lisp reader treats infinities and NaNs.
18470 Do not assume that floating-point numbers represent EMACS_INT
18471 without losing information; this is not true on most 64-bit hosts.
18472 Avoid double-rounding errors, by insisting on integers when
18473 parsing non-base-10 numbers, as the documentation specifies.
18474 * lisp.h (string_to_number): New decl, replacing ...
18475 (isfloat_string): Remove.
18476 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
18477 (read1): Do not accept +. and -. as integers; this
18478 appears to have been a coding error. Similarly, do not accept
18479 strings like +-1e0 as floating point numbers. Do not report
18480 overflow for integer overflows unless the base is not 10 which
18481 means we have no simple and reliable way to continue.
18482 Break out the floating-point parsing into a new
18483 function string_to_number, so that Fstring_to_number parses
18484 floating point numbers consistently with the Lisp reader.
18485 (digit_to_number): Move here from data.c. Make it static inline.
18486 (E_CHAR, EXP_INT): Remove, replacing with ...
18487 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
18488 (string_to_number): New function, replacing isfloat_string.
18489 This function checks for valid syntax and produces the resulting
18490 Lisp float number too. Rework it so that string-to-number
18491 no longer mishandles examples like "1.0e+". Use strtoumax,
18492 so that overflow for non-base-10 numbers is reported only when
18493 there's no portable and simple way to convert to floating point.
18495 * textprop.c (set_text_properties_1): Rewrite for clarity,
18496 and to avoid GCC warning about integer overflow.
18498 * intervals.h (struct interval): Use EMACS_INT for members
18499 where EMACS_UINT might cause problems. See
18500 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
18501 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
18502 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
18504 (offset_intervals): Tell GCC not to worry about length overflow
18505 when negating a negative length.
18507 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
18508 (overrun_check_free): Likewise.
18510 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
18511 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
18514 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18515 (gnutls_make_error): Rename local to avoid shadowing.
18516 (gnutls_emacs_global_deinit): ifdef out; not used.
18517 (Fgnutls_boot): Use const for pointer to readonly storage.
18518 Comment out unused local. Fix pointer signedness problems.
18520 * lread.c (openp): Don't stuff size_t into an 'int'.
18521 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
18522 about possible signed overflow.
18524 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18525 (GDK_KEY_g): Don't define if already defined.
18526 (xg_prepare_tooltip): Avoid pointer signedness problem.
18527 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
18529 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
18530 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
18532 * xfns.c (Fx_window_property): Simplify a bit,
18533 to make a bit faster and to avoid GCC 4.6.0 warning.
18534 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
18536 * fns.c (internal_equal): Don't assume size_t fits in int.
18538 * alloc.c (compact_small_strings): Tighten assertion a little.
18540 Replace pEd with more-general pI, and fix some printf arg casts.
18541 * lisp.h (pI): New macro, generalizing old pEd macro to other
18542 conversion specifiers. For example, use "...%"pI"d..." rather
18543 than "...%"pEd"...".
18544 (pEd): Remove. All uses replaced with similar uses of pI.
18545 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
18546 * alloc.c (check_pure_size): Don't overflow by converting size to int.
18547 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
18548 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
18549 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
18550 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
18551 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
18553 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
18554 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
18555 * print.c (safe_debug_print, print_object): Likewise.
18556 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
18558 Use pI instead of if-then-else-abort. Use %p to avoid casts,
18559 avoiding the 0 flag, which is not portable.
18560 * process.c (Fmake_network_process): Use pI to avoid cast.
18561 * region-cache.c (pp_cache): Likewise.
18562 * xdisp.c (decode_mode_spec): Likewise.
18563 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
18564 behavior on 64-bit hosts with printf arg.
18565 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
18566 (x_stop_queuing_selection_requests): Likewise.
18567 (x_get_window_property): Don't truncate byte count to an 'int'
18570 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
18571 here, since it parses constructs like leading '-' and spaces,
18572 which are not wanted; and it overflows with large numbers.
18573 Instead, simply match F[0-9]+, which is what is wanted anyway.
18575 * alloc.c: Remove unportable assumptions about struct layout.
18576 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
18577 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
18578 (allocate_vectorlike, make_pure_vector): Use the new macros,
18579 plus offsetof, to remove unportable assumptions about struct layout.
18580 These assumptions hold on all porting targets that I know of, but
18581 they are not guaranteed, they're easy to remove, and removing them
18582 makes further changes easier.
18584 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
18585 This doesn't fix a bug but makes the code clearer.
18586 (string_overrun_cookie): Now const. Use initializers that
18587 don't formally overflow signed char, to avoid warnings.
18588 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
18589 can cause Emacs to crash when string overrun checking is enabled.
18590 (allocate_buffer): Don't assume sizeof (struct buffer) is a
18591 multiple of sizeof (EMACS_INT); it need not be, if
18592 alignof(EMACS_INT) < sizeof (EMACS_INT).
18593 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
18595 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
18597 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
18599 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
18601 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
18602 supposed to be handshaking. (Bug#8556)
18603 Reported by Paul Eggert <eggert@cs.ucla.edu>.
18605 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
18607 * lisp.h (Qdebug): List symbol.
18608 * eval.c (Qdebug): Restore global linkage.
18609 * keyboard.c (debug-on-event): New variable.
18610 (handle_user_signal): Break into debugger when debug-on-event
18611 matches the current signal symbol.
18613 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
18615 * alloc.c (check_sblock, check_string_bytes)
18616 (check_string_free_list): Convert to standard C.
18618 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
18620 * w32.c (emacs_gnutls_push): Fix typo.
18622 2011-04-25 Eli Zaretskii <eliz@gnu.org>
18624 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
18625 "cast to pointer from integer of different size".
18627 Improve doprnt and its use in verror. (Bug#8545)
18628 * doprnt.c (doprnt): Document the set of format control sequences
18629 supported by the function. Use SAFE_ALLOCA instead of always
18632 * eval.c (verror): Don't limit the buffer size at size_max-1, that
18633 is one byte too soon. Don't use xrealloc; instead xfree and
18636 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
18638 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
18641 * gnutls.c: Renamed global_initialized to
18642 gnutls_global_initialized. Added internals for the
18643 :verify-hostname-error, :verify-error, and :verify-flags
18644 parameters of `gnutls-boot' and documented those parameters in the
18645 docstring. Start callback support.
18646 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
18647 unless a fatal error occurred. Call gnutls_alert_send_appropriate
18648 on error. Return error code.
18649 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
18650 (emacs_gnutls_read): Likewise.
18651 (Fgnutls_boot): Return handshake error code.
18652 (emacs_gnutls_handle_error): New function.
18653 (wsaerror_to_errno): Likewise.
18655 * w32.h (emacs_gnutls_pull): Add prototype.
18656 (emacs_gnutls_push): Likewise.
18658 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
18659 (emacs_gnutls_push): Likewise.
18661 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)

18976 * process.c (send_process): Adjust to the new signatures of
18977 emacs_write and emacs_gnutls_write. Do not attempt to store

19170 * font.c (font_close_object): Now static.
19171 * font.h (font_close_object): Remove.
19172 * fontset.c (FONTSET_OBJLIST): Remove.
19173 (free_realized_fontset) #if-0 the body, which does nothing.
19174 (face_suitable_for_char_p): #if-0, as it's never called.
19175 * fontset.h (face_suitable_for_char_p): Remove decl.
19176 * xfaces.c (face_at_string_position):
19177 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,
19178 since 0 is always ASCII.
19180 * fns.c (weak_hash_tables): Now static.
19182 * fileio.c: Make symbols static if they're not exported.

19201 * editfns.c, lisp.h (get_operating_system_release): Remove.
19202 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
19203 worth the hassle of breaking this out.
19205 * xterm.c: Make symbols static if they're not exported.
19206 (x_raise_frame, x_lower_frame, x_wm_set_window_state):

19309 * buffer.c (buffer_count): Remove unused var.

19318 * atimer.h (run_all_atimers): Remove; not exported.
19320 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
19321 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
19322 was inaccessible from Lisp.
19323 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
19324 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
19326 alloc.c: Import and export fewer symbols, and remove unused items.
19327 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
19329 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
19330 it's not optimized away by whole-program optimization.
19331 (message_enable_multibyte, free_misc): Remove.
19332 (catchlist, handlerlist, mark_backtrace):
19333 Declare only if BYTE_MARK_STACK.

19342 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
19343 (mark_backtrace): Define only if BYTE_MARK_STACK.
19344 * xdisp.c (message_enable_multibyte): Now static.
19346 Declare Lisp_Object Q* variables to be 'static' if not exported.
19347 This makes it easier for human readers (and static analyzers)
19348 to see whether these variables are used from other modules.
19349 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
19350 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:

19359 Remove decls of unexported vars.
19360 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
19362 * lisp.h (DEFINE_FUNC): Make sname 'static'.
19364 Make Emacs functions such as Fatom 'static' by default.
19365 This makes it easier for human readers (and static analyzers)
19366 to see whether these functions can be called from other modules.
19367 DEFUN now defines a static function. To make the function external
19368 so that it can be used in other C modules, use the new macro DEFUE.
19369 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
19370 (Finit_image_library):
19371 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
19372 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
19373 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
19374 Remove decls, since these functions are now static.
19375 (Funintern, Fget_internal_run_time): New decls, since these functions
19376 were already external.
19378 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
19379 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

19385 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
19386 Mark functions with DEFUE instead of DEFUN,
19387 if they are used in other modules.
19388 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
19389 decls for now-static functions.
19390 * buffer.h (Fdelete_overlay): Remove decl.
19391 * callproc.c (Fgetenv_internal): Mark as internal.
19392 * composite.c (Fremove_list_of_text_properties): Remove decl.

19399 * fileio.c (Fmake_symbolic_link): New forward static decl.
19400 * image.c (Finit_image_library): New forward static decl.
19401 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
19402 * intervals.h (Fprevious_property_change):
19403 (Fremove_list_of_text_properties): Remove decls.
19404 * keyboard.c (Fthis_command_keys): Remove decl.
19405 (Fcommand_execute): New forward static decl.

19421 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
19423 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
19426 2011-04-13 Eli Zaretskii <eliz@gnu.org>
19428 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
19429 when at ZV. (Bug#8487)
19431 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
19433 * charset.c (Fclear_charset_maps): Use xfree instead of free.
19435 * keyboard.c (parse_tool_bar_item): Likewise.
19436 * sound.c (sound_cleanup, alsa_close): Likewise.
19437 * termcap.c (tgetent): Likewise.
19438 * xfns.c (x_default_font_parameter): Likewise.
19439 * xsettings.c (read_and_apply_settings): Likewise.
19441 * alloc.c (overrun_check_malloc, overrun_check_realloc)
19442 (overrun_check_free): Protoize.
19444 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
19446 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
19447 since callers should never pass a negative size.
19448 Change the signature to match that of plain 'read' and 'write'; see
19449 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
19450 * lisp.h: Update prototypes of emacs_write and emacs_read.
19452 2011-04-11 Eli Zaretskii <eliz@gnu.org>
19454 * xdisp.c (redisplay_window): Don't try to determine the character
19455 position of the scroll margin if the window start point w->startp
19456 is outside the buffer's accessible region. (Bug#8468)
19458 2011-04-10 Eli Zaretskii <eliz@gnu.org>
19460 Fix write-region and its subroutines for buffers > 2GB.
19461 * fileio.c (a_write, e_write): Modify declaration of arguments and
19462 local variables to support buffers larger than 2GB.
19463 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
19465 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
19466 argument, local variables, and return value.
19468 * lisp.h: Update prototypes of emacs_write and emacs_read.
19470 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
19472 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
19474 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
19476 Fix more problems found by GCC 4.6.0's static checks.
19478 * xdisp.c (vmessage): Use a better test for character truncation.
19480 * charset.c (load_charset_map): <, not <=, for optimization,
19481 and to avoid potential problems with integer overflow.
19482 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
19483 * casetab.c (set_identity, shuffle): Likewise.
19484 * editfns.c (Fformat): Likewise.
19485 * syntax.c (skip_chars): Likewise.
19487 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
19488 This also lets GCC 4.6.0 generate slightly better loop code.
19490 * callint.c (Fcall_interactively): <, not <=, for optimization.
19491 (Fcall_interactively): Count the number of arguments produced,
19492 not the number of arguments given. This is simpler and lets GCC
19493 4.6.0 generate slightly better code.
19495 * ftfont.c: Distingish more carefully between FcChar8 and char.
19496 The previous code passed unsigned char * to a functions like
19497 strlen and xstrcasecmp that expect char *, which does not
19498 conform to the C standard.
19499 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
19500 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
19501 char * when the C standard requires it.
19503 * keyboard.c (read_char): Remove unused var.
19505 * eval.c: Port to Windows vsnprintf (Bug#8435).
19506 Include <limits.h>.
19507 (SIZE_MAX): Define if the headers do not.
19508 (verror): Do not give up if vsnprintf returns a negative count.
19509 Instead, grow the buffer. This ports to Windows vsnprintf, which
19510 does not conform to C99. Problem reported by Eli Zaretskii.
19511 Also, simplify the allocation scheme, by avoiding the need for
19512 calling realloc, and removing the ALLOCATED variable.
19514 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
19516 Remove invocations of doprnt, as Emacs now uses vsnprintf.
19517 But keep the doprint source code for now, as we might revamp it
19518 and use it again (Bug#8435).
19519 * lisp.h (doprnt): Remove.
19520 * Makefile.in (base_obj): Remove doprnt.o.
19521 * deps.mk (doprnt.o): Remove.
19523 error: Print 32- and 64-bit integers portably (Bug#8435).
19524 Without this change, on typical 64-bit hosts error ("...%d...", N)
19525 was used to print both 32- and 64-bit integers N, which relied on
19526 undefined behavior.
19527 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
19528 * lisp.h (error, verror): Mark as printf-like functions.
19529 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
19530 Report overflow in size calculations when allocating printf buffer.
19531 Do not truncate output string at its first null byte.
19532 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
19533 Truncate the output at a character boundary, since vsnprintf does not
19535 * charset.c (check_iso_charset_parameter): Convert internal
19536 character to string before calling 'error', since %c now has the
19538 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
19539 overflow when computing char to be passed to 'error'. Do not
19540 pass Lisp_Object to 'error'; pass the integer instead.
19541 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
19542 formatted with plain %d.
19544 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.

19559 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
19560 return ssize_t not "int", and use size_t as the buffer length.
19561 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
19562 * gnutls.h: Update declarations.
19563 * process.c (read_process_output): Use ssize_t, to match.

19679 This avoids several warnings with gcc -Wstrict-overflow.
19680 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
19681 directly, rather than having caller test rule sign. This avoids
19682 some unnecessary tests.
19683 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
19684 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
19685 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.

19702 since the condition is always true at first.
19704 * intervals.c (graft_intervals_into_buffer): Mark var as used.

19735 * eval.c (funcall_lambda): Rename local to avoid shadowing.
19737 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
19738 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
19739 can always succeed if overflow has undefined behavior.
19741 * search.c (boyer_moore, wordify): Remove vars set but not used.
19742 (wordify): Omit three unnecessary tests.
19744 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

19772 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
19773 that are set but not used.
19775 * xfns.c (make_invisible_cursor): Don't return garbage
19776 if XCreateBitmapFromData fails (Bug#8410).
19778 * xselect.c (x_get_local_selection, x_handle_property_notify):
19779 Remove vars that are set but not used.
19781 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

19799 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
19800 (decode_coding_charset): Remove vars that are set but not used.

19803 that is set but not used.
19805 * print.c (print_object): Remove var that is set but not used.
19807 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
19808 The gnulib version avoids calling malloc in the usual case,
19809 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
19810 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
19811 * filelock.c (current_lock_owner): Likewise.
19812 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
19813 * sysdep.c: Include allocator.h, careadlinkat.h.
19814 (emacs_no_realloc_allocator): New static constant.
19815 (emacs_readlink): New function.
19816 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
19817 ../lib/careadlinkat.h.
19819 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
19821 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
19822 first non-nil return value).

19838 (get_per_char_metric): Remove parameter `f', unused since
19839 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

19884 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
19885 (FletX, Flet): Obey lexical binding.
19886 (Fcommandp): Handle closures.
19887 (Feval): New `lexical' arg.
19888 (eval_sub): New function extracted from Feval. Use it almost
19889 everywhere where Feval was used. Look up vars in lexical env.
19891 (Ffunctionp): Move from subr.el.

19893 (apply_lambda): Remove `eval_flags'.
19894 (funcall_lambda): Handle closures and new byte-code-functions.
19895 (Fspecial_variable_p): New function.
19896 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,

19899 * doc.c (Fdocumentation, store_function_docstring):
19900 * data.c (Finteractive_form): Handle closures.
19902 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
19905 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
19907 (exec_byte_code): New function extracted from Fbyte_code to handle new
19908 calling convention for byte-code-functions. Add new byte-codes.

19923 (redisplay_window): Even when falling back on "recentering",
19924 position point in the window according to scroll-conservatively,
19925 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
19927 (try_scrolling): When point is above the window, allow searching
19928 as far as scroll_max, or one screenful, to compute vertical
19929 distance from PT to the scroll margin position. This prevents
19930 try_scrolling from unnecessarily failing when
19931 scroll-conservatively is set to a value slightly larger than the
19932 window height. Clean up the case of PT below the margin at bottom
19933 of window: scroll_max can no longer be INT_MAX. When aggressive
19934 scrolling is in use, don't let point enter the opposite scroll
19935 margin as result of the scroll.
19936 (syms_of_xdisp) <scroll-conservatively>: Document the
19937 threshold of 100 lines for never-recentering scrolling.

20004 * keyboard.c (syms_of_keyboard): Use the same style as later
20005 in this function when indexing through an array. This also
20006 works around GCC bug 48267.
20008 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
20010 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
20012 * chartab.c (sub_char_table_ref_and_range): Redo for slight
20013 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
20015 * keyboard.c, keyboard.h (num_input_events): Now size_t.
20016 This avoids undefined behavior on integer overflow, and is a bit
20017 more convenient anyway since it is compared to a size_t variable.
20019 Variadic C functions now count arguments with size_t, not int.
20020 This avoids an unnecessary limitation on 64-bit machines, which
20021 caused (substring ...) to crash on large vectors (Bug#8344).
20022 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
20023 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
20024 All variadic functions and their callers changed accordingly.
20025 (struct gcpro.nvars): Now size_t, not int. All uses changed.

20027 * editfns.c (general_insert_function): Likewise.
20028 * eval.c (struct backtrace.nargs, interactive_p)
20029 (internal_condition_case_n, run_hook_with_args, apply_lambda)
20030 (funcall_lambda, mark_backtrace): Likewise.
20031 * fns.c (concat): Likewise.
20032 * frame.c (x_set_frame_parameters): Likewise.
20033 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
20034 0 if not found, not -1. All callers changed.
20036 * alloc.c (garbage_collect): Don't assume stack size fits in int.
20037 (stack_copy_size): Now size_t, not int.
20038 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

20059 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
20060 don't set the hook to nil, but remove the offending function instead.
20061 (Qcommand_hook_internal): Remove, unused.
20062 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
20063 Vcommand_hook_internal.
20065 * eval.c (enum run_hooks_condition): Remove.
20066 (funcall_nil, funcall_not): New functions.
20067 (run_hook_with_args): Call each function through a `funcall' argument.

20077 * print.c (strout): Remove parameter `multibyte', unused since
20078 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
20080 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
20081 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.

20094 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
20095 All callers changed.
20097 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
20099 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

20128 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
20130 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
20132 * w32.c (read_unc_volume): Use parameter `henum', instead of
20133 global variable `wget_enum_handle'.
20135 * keymap.c (describe_vector): Remove parameters `indices' and
20136 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

20242 * callint.c (Fcall_interactively):
20243 * buffer.c (Fkill_all_local_variables):
20244 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
20246 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
20247 unconditionally since it does the check itself.
20249 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
20251 Fix more problems found by GCC 4.5.2's static checks.
20253 * coding.c (encode_coding_raw_text): Avoid unnecessary test
20254 the first time through the loop, since we know p0 < p1 then.
20255 This also avoids a gcc -Wstrict-overflow warning.
20257 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
20258 leading to a memory leak, possible in functions like
20259 load_charset_map_from_file that can allocate an unbounded number
20260 of objects (Bug#8318).
20262 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
20263 that could (at least in theory) be that large.
20265 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
20266 This is less likely to overflow, and avoids undefined behavior if
20267 overflow does occur. All callers changed. Use strtoul to scan
20268 for the unsigned long integer.
20269 (pint2hrstr): Simplify and tune code slightly.
20270 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

20285 * process.c (Fmake_network_process): Use socklen_t, not int,
20286 where POSIX says socklen_t is required in portable programs.
20287 This fixes a porting bug on hosts like 64-bit HP-UX, where
20288 socklen_t is wider than int (Bug#8277).
20289 (Fmake_network_process, server_accept_connection):
20290 (wait_reading_process_output, read_process_output):
20293 * process.c: Rename or move locals to avoid shadowing.

20303 Make tparam.h and terminfo.c consistent.
20304 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
20305 Include tparam.h instead, since it declares them.
20306 * cm.h (PC): Remove extern decl; tparam.h now does this.
20307 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
20308 * terminfo.c: Include tparam.h, to check interfaces.
20309 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
20310 (tparam): Adjust signature to match interface in tparam.h;
20311 this removes some undefined behavior. Check that outstring and len
20312 are zero, which they always are with Emacs.
20313 * tparam.h (PC, BC, UP): New extern decls.
20315 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
20316 (xftfont_open): Rename locals to avoid shadowing.
20318 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
20319 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.

20321 (ftfont_list): Remove unused local.
20322 (get_adstyle_property, ftfont_pattern_entity):
20323 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
20324 Rename locals to avoid shadowing.
20326 * xfont.c (xfont_list_family): Mark var as initialized.
20328 * xml.c (make_dom): Now static.
20330 * composite.c (composition_compute_stop_pos): Rename local to
20332 (composition_reseat_it): Remove unused locals.
20333 (find_automatic_composition, composition_adjust_point): Likewise.
20334 (composition_update_it): Mark var as initialized.
20335 (find_automatic_composition): Mark vars as initialized,
20336 with a FIXME (Bug#8290).
20338 character.h: Rename locals to avoid shadowing.
20339 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
20340 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
20341 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
20342 (BUF_DEC_POS): Be more systematic about renaming local temporaries
20343 to avoid shadowing.
20345 * textprop.c (property_change_between_p): Remove; unused.
20347 * intervals.c (interval_start_pos): Now static.
20349 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
20351 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
20352 Rename locals to avoid shadowing.
20354 * sound.c (wav_play, au_play, Fplay_sound_internal):
20355 Fix pointer signedness.
20356 (alsa_choose_format): Remove unused local var.
20357 (wav_play): Initialize a variable to 0, to prevent undefined
20358 behavior (Bug#8278).
20360 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
20362 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
20364 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
20365 clobbering (Bug#8298).
20366 * sysdep.c (sys_subshell): Likewise.
20367 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
20369 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
20370 This should get cleaned up, so that child_setup has the
20371 same signature on all platforms.
20373 * callproc.c (call_process_cleanup): Now static.
20374 (relocate_fd): Rename locals to avoid shadowing.
20376 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
20378 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
20379 not to be necessary, and produces flickering.
20381 2011-03-20 Glenn Morris <rgm@gnu.org>
20383 * config.in: Remove file.
20385 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
20387 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
20388 are now in src/globals.h.

20415 (sigchld_handler): Now static.
20417 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
20418 That way, the code declares only the vars that it needs.
20419 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
20420 * s/cygwin.h (PTY_ITERATION): Likewise.
20421 * s/darwin.h (PTY_ITERATION): Likewise.

20424 * s/irix6-5.h (PTY_OPEN): Declare stb, to loosen coupling.
20425 * process.c (allocate_pty): Don't declare stb unless it's needed.
20427 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
20428 (CONSTANTLIM): Remove; unused.
20429 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
20430 Define only if needed.
20432 * unexelf.c (unexec): Name an expression,
20433 to avoid gcc -Wbad-function-cast warning.
20434 Use a different way to cause a compilation error if anyone uses
20435 n rather than nn, a way that does not involve shadowing.
20436 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
20438 * deps.mk (unexalpha.o): Remove; unused.
20440 New file unexec.h, the (simple) interface for unexec (Bug#8267).
20441 * unexec.h: New file.
20442 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
20443 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
20444 Depend on unexec.h.
20445 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.

20504 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
20505 some of which prompt warnings from gcc -Wbad-function-cast.
20506 (Fformat_time_string, Fencode_time, Finsert_char):

20535 (Fmemory_limit): Cast sbrk's returned value to char *.
20537 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

20543 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
20544 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
20545 to use the following functions instead of these macros.
20546 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
20547 EMACS_INT, since callers assume the returned value fits in int.
20548 (upcase1): Likewise, for UPCASE_TABLE.
20549 (uppercasep, lowercasep, upcase): New static inline functions.
20550 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

20560 (regex_compile, re_match_2_internal): Mark locals as initialized.
20561 (RETALLOC_IF): Define only if needed.
20562 (WORDCHAR_P): Likewise. This one is never needed, but is used
20563 only in a comment talking about a compiler bug, so put inside
20564 the #if 0 of that comment.
20565 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
20566 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

20593 New macros, so that the caller can use some names other than
20594 gcpro1, gcpro2, etc.
20595 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
20597 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
20598 argument, for consistency with GCPRO2_VAR, etc: it is now the

20601 * dired.c (directory_files_internal, file_name_completion):
20602 Rename locals to avoid shadowing.
20604 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
20605 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
20606 dired.c's scmp function, had undefined behavior.
20607 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
20608 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
20609 * buffer.h: ... to here, because these macros use current_buffer,
20610 and the new implementation with inline functions needs to have
20611 current_buffer in scope now, rather than later when the macros
20613 (downcase, upcase1): New static inline functions.
20614 (DOWNCASE, UPCASE1): Reimplement using these functions.
20615 This avoids undefined behavior in expressions like
20616 DOWNCASE (x) == DOWNCASE (y), which previously suffered
20617 from race conditions in accessing the global variables
20618 case_temp1 and case_temp2.
20619 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
20620 * lisp.h (case_temp1, case_temp2): Remove their decls.
20621 * character.h (ASCII_CHAR_P): Move from here ...
20622 * lisp.h: ... to here, so that the inline functions mentioned
20623 above can use them.

20630 (file_name_as_directory): Use const pointers when appropriate.
20631 (Fexpand_file_name): Likewise. In particular, newdir might
20632 point at constant storage, so make it a const pointer.

20634 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
20636 (Fset_file_times, Finsert_file_contents, auto_save_error):

20641 to avoid shadowing.
20643 * marker.c (bytepos_to_charpos): Remove; unused.
20645 * lisp.h (verify_bytepos, count_markers): New decls,
20646 so that gcc does not warn that these functions aren't declared.
20648 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
20649 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
20650 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
20651 (copy_text): Remove unused local var.

20656 * buffer.c (fix_overlays_before): Mark locals as initialized.
20657 (fix_start_end_in_overlays): Likewise. This function should be
20658 simplified by using pointers-to-pointers, but that's a different
20660 (switch_to_buffer_1): Now static.
20661 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
20662 (report_overlay_modification): Rename locals to avoid shadowing.

20665 Fix pointer signedness issue.
20666 (sys_subshell): Mark local as volatile if checking for lint,
20667 to suppress a gcc -Wclobbered warning that does not seem to be right.
20668 (MAXPATHLEN): Define only if needed.
20670 * process.c (serial_open, serial_configure): Move decls from here ...
20671 * systty.h: ... to here, so that they can be checked.
20673 * fns.c (get_random, seed_random): Move extern decls from here ...
20674 * lisp.h: ... to here, so that they can be checked.
20676 * sysdep.c (reset_io): Now static.
20677 (wait_for_termination_signal): Remove; unused.

20685 (describe_map_tree):
20686 Rename locals to avoid shadowing.

20835 For example, without this patch (encode-time 0 0 0 1 1
20836 1152921504606846976) returns the obviously-bogus value (-948597
20837 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
20838 reports time overflow. See
