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.
8 (Fset_buffer_modified_p): Use buffer_window_count to check
9 whether the buffer is displayed in some window.
10 * xdisp.c (message_dolog): Likewise.
12 2012-12-23 Eli Zaretskii <eliz@gnu.org>
14 * w32.c (acl_set_file): If setting the file security descriptor
15 fails, and the new DACL is identical to the existing one, silently
16 return success. This fixes problems for users backing up their
17 own files without having the necessary privileges for setting
20 * w32proc.c (reader_thread): Do not index fd_info[] with negative
22 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
23 after WaitForSingleObject returns normally. This expedites reader
24 thread shutdown when delete_child triggers it.
25 (reap_subprocess): More accurate commentary for why we call
26 delete_child only when cp->fd is negative.
28 * w32.c (sys_close): Do not call delete_child on a subprocess
29 whose handle is not yet closed. Instead, set its file descriptor
30 to a negative value, so that reap_subprocess will call
31 delete_child on that subprocess when its SIGCHLD arrives. This
32 avoids closing handles used for communications between sys_select
33 and reader_thread, which doesn't give sys_select a chance to
34 notice that the process exited and invoke the SIGCHLD handler for
37 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
39 * nsfns.m (Fns_do_applescript): Run event loop until script has
40 been executed (Bug#12969).

51 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
53 2012-12-21 Eli Zaretskii <eliz@gnu.org>
55 * fileio.c (Finsert_file_contents): Doc fix.
57 * w32proc.c (new_child, delete_child, find_child_pid): For a
58 subprocess, consider its slot being in use as long as its process
59 handle (procinfo.hProcess) is not NULL. This avoids reusing the
60 slot when a new process is started immediately after killing
61 another one, without waiting enough time for the first process to
62 be reaped and resources allocated for it be orderly freed.
64 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
66 2012-12-21 Chong Yidong <cyd@gnu.org>
68 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
70 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
72 2012-12-21 Eli Zaretskii <eliz@gnu.org>
74 * w32.c (get_name_and_id): Always pass NULL as the first argument
75 of lookup_account_sid. Avoids crashes with UNC file names that
76 refer to DFS domains, not to specific machine names. (Bug#12621)
77 Remove now unused argument FNAME; all callers changed.
78 (get_file_owner_and_group): Remove now unused argument FNAME; all
81 2012-12-21 Chong Yidong <cyd@gnu.org>
83 * editfns.c (Finsert_char): Since read-char-by-name now signals an
84 error for invalid chars, don't check for a nil return value.
86 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
88 Avoid calls to CHAR_TO_BYTE if byte position is known.
89 * editfns.c (make_buffer_string_both): Use move_gap_both.
90 (Fbuffer_string): Use make_buffer_string_both.
91 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
93 (buf_bytepos_to_charpos): Likewise.
94 (charpos_to_bytepos): Remove.
95 * fileio.c (Finsert_file_contents): Use move_gap_both.

98 names for byte positions.
99 * lisp.h (charpos_to_bytepos): Remove prototype.
100 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
101 * insdel.c (move_gap): Likewise.

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

140 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
141 propagate redisplay's scrolling (if any) to the right window.
142 (redisplay_internal): Use ensure_selected_frame.
143 (display_mode_lines): Complete last fix.
144 * window.c (select_window_1): New func, extracted from select_window.
145 (select_window): Use it.
146 * window.h (select_window_1): Declare.
148 2012-12-17 Eli Zaretskii <eliz@gnu.org>

172 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
174 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
175 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
176 for some of that bug's symptoms can now cause Emacs to abort.
177 Remove the workaround.
178 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
179 The bug that caused SIGCHLD to get lost has been fixed, and the

182 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
184 * sysdep.c (emacs_abort): Bump backtrace size to 40.

190 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
191 (Fcopy_file): Change last arg to `preserve_extended_attributes'

195 * Makefile.in (LIBACL_LIBS): New macro.
198 2012-12-15 Paul Eggert <eggert@cs.ucla.edu>
200 * fileio.c (internal_delete_file): Use bool for boolean.

207 (register_child): First argument is now pid_t.
208 (record_infile, record_pending_deletion): New prototypes.
210 * w32proc.c (new_child): Initialize input_file and
211 pending_deletion members of the child.
212 (delete_child): Delete the child's temporary input file, if any,
213 that is pending deletion.
214 (register_child): First argument is now pid_t.
215 (record_infile, record_pending_deletion): New functions.
216 (reap_subprocess): Fix a typo in DebPrint string.
217 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
219 * fileio.c (internal_delete_file): Return an int again: non-zero
220 if delete-file succeeds, zero otherwise.
222 * lisp.h (internal_delete_file): Adjust prototype.
224 * callproc.c (Fcall_process): Don't overwrite infile with result
226 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
227 asynchronous subprocess, record the name of the input file name,
229 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
230 delete the file, record it as pending deletion when the subprocess
233 2012-12-14 Eli Zaretskii <eliz@gnu.org>
235 * editfns.c [HAVE_PWD_H]: Include grp.h.
237 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.
239 2012-12-14 Paul Eggert <eggert@cs.ucla.edu>
241 Fix permissions bugs with setgid directories etc. (Bug#13125)
242 * dired.c (Ffile_attributes): Return t as the 9th attribute,
243 to mark it as a placeholder. The old value was often wrong.

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

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

290 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
292 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
293 files, fixing a regression from 24.2.
294 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
296 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
298 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
299 fstat shouldn't fail, and if it does fail copy-file should not proceed.
300 Remove unnecessary S_ISLNK test, as (contra the comments) this
301 function can't copy symlinks. Improve quality of error message
302 when attempting to copy files that are neither regular files nor
305 2012-12-12 Dmitry Antipov <dmantipov@yandex.ru>

313 2012-12-12 Daniel Colascione <dancol@dancol.org>
315 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
316 the dumped Emacs is not a sparse file, greatly improving Cygwin
317 "make bootstrap" performance.
319 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
321 * inotify.c (inotify_callback): Generate an Emacs event for every
322 incoming inotify event.
324 2012-12-11 Eli Zaretskii <eliz@gnu.org>
326 * xdisp.c (handle_face_prop): Fix logic of computing
327 it->start_of_box_run_p.
328 (append_space_for_newline): If the glyph row is R2L, reset the
329 iterator's end_of_box_run_p flag before prepending the space glyph.
330 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
331 iterator's start_of_box_run_p flag before prepending the stretch.
332 (append_glyph, produce_image_glyph, append_composite_glyph)
333 (append_stretch_glyph, append_glyphless_glyph): Reverse the
334 left_box_line_p and right_box_line_p flags of the glyph for R2L
335 glyph rows. (Bug#13011)
337 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
339 * buffer.c (Fset_buffer_multibyte): Do not force redisplay
340 if changed buffer is not shown in a window.

342 * window.c (replace_buffer_in_windows_safely): Do nothing
343 if buffer is not shown in a window.

347 2012-12-11 Eli Zaretskii <eliz@gnu.org>
349 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
350 encoded_file_name, which is what it is.

385 (hinst): Remove unneeded extern declaration.
386 (_start): Remove initialization of above variables; remove
387 initialization of hinst, as cache_system_info now does that.
389 * emacs.c (main): Call cache_system_info early in startup; we
390 previously weren't calling it in Cygwin builds.
392 * Makefile.in (ntsource, WINDRES, W32_RES, W#@_RES_LINK):

515 displayed on the left or the right margin, don't consider it as a
516 factor in cursor positioning. (Bug#13108)
518 2012-12-10 Martin Rudalics <rudalics@gmx.at>
520 * editfns.c (Fcompare_buffer_substrings): Reword doc-string.
522 2012-12-10 Paul Eggert <eggert@cs.ucla.edu>
524 * fileio.c (Fsubstitute_in_file_name): Use ptrdiff_t, not int,
527 2012-12-08 Eli Zaretskii <eliz@gnu.org>
529 * w32.c (unsetenv): Return 0 if the input string is too long.
531 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
533 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).
534 * alloc.c (xputenv): New function.
535 * dbusbind.c (Fdbus_init_bus):
537 * xterm.c (x_term_init):
538 Use xputenv instead of setenv or putenv, to detect memory exhaustion.
539 * editfns.c (initial_tz): Move static var decl up.
540 (tzvalbuf_in_environ): New static var.
541 (init_editfns): Initialize these two static vars.
542 (Fencode_time): Don't assume arbitrary limit on EMACS_INT width.
543 Save old TZ value on stack, if it's small.
544 (Fencode_time, set_time_zone_rule): Don't modify 'environ' directly;
545 instead, use xputenv+unsetenv to set and restore TZ.
546 (environbuf): Remove static var. All uses removed.
547 (Fset_time_zone_rule): Do not save TZ and environ;
548 no longer needed here.
549 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
550 Move to inside set_time_zone_rule; they don't need file scope any more.
551 (set_time_zone_rule): Maintain the TZ=value string separately.
552 (syms_of_editfns): Don't initialize initial_tz;
553 init_editfns now does it.
554 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
555 * lisp.h (xputenv): New decl.
557 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
559 * w32fns.c (emacs_abort): Don't do arithmetics on void pointers.
561 2012-12-08 Eli Zaretskii <eliz@gnu.org>
563 * w32.c (unsetenv, sys_putenv): New functions.
565 2012-12-08 Chong Yidong <cyd@gnu.org>
567 * editfns.c (Finsert_char): Make the error message more
568 informative (Bug#12992).
570 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
572 Simplify get_lim_data.
573 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
574 Remove USG and vlimit methods; no longer used these days.
575 Add #error catchall just in case.
577 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
578 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
579 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
580 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
581 (deleted_pid_list, Fdelete_process, create_process)
582 (record_child_status_change, handle_child_signal, deliver_child_signal)
583 (init_process_emacs, syms_of_process):
584 Assume SIGCHLD is defined.
585 (parse_signal): Remove. All uses removed.
586 (abbr_to_signal): New static function.
587 (Fsignal_process): Use it to convert signal names to ints.
588 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
589 kill (getpgrp (), ...).
590 (emacs_sigaction_init): Assume SIGCHLD is defined.
591 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,
592 SIGPIPE, and SIGQUIT are defined. Do not worry about SIGCLD any more.
593 * syssignal.h (EMACS_KILLPG): Remove.
594 All uses replaced by 'kill' with a negative pid.
595 (SIGCHLD): Remove definition, as we now assume SIGCHLD.
596 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
598 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
600 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
601 This will cause a production Emacs to dump core instead of
604 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
606 * frame.c (make_frame): Do not set window's buffer to t.
607 * window.c (Fsplit_window_internal): Likewise. Previously it was
608 used to indicate that the window is being set up. Now we use
609 set_window_buffer for all new windows, so the condition in ...
610 (Fset_window_buffer): ... is always true and can be removed.
612 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
614 Convenient macro to check whether the buffer is hidden.
615 * buffer.h (BUFFER_HIDDEN_P): New macro.
616 * frame.c (make_frame): Use it. Adjust comment.
617 * buffer.c (candidate_buffer): New function.
618 (Fother_buffer, other_buffer_safely): Use it.
620 2012-12-06 Eli Zaretskii <eliz@gnu.org>
622 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
623 if the child process is still running. Instead, exit the wait
624 loop and return zero. (Bug#13086)
626 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
628 * frame.h (x_char_width, x_char_height): Remove prototypes.

630 * xfns.c (x_char_width, x_char_height): Remove.
631 * w32fns.c (x_char_width, x_char_height): Likewise.
632 * nsfns.c (x_char_width, x_char_height): Likewise.

635 (Fframe_char_height): Likewise with FRAME_LINE_HEIGHT.
636 * keyboard.c (command_loop_1): Remove prototype.
637 (command_loop_2, top_level_1): Add static to match prototype.
639 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
641 Fix a recently-introduced delete-process race condition.
642 * callproc.c, process.h (record_kill_process):
643 New function, containing part of the old call_process_kill.
644 (call_process_kill): Use it.
645 This does not change call_process_kill's behavior.
646 * process.c (Fdelete_process): Use record_kill_process to fix a
647 race condition that could cause Emacs to lose track of a child.
649 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
651 Avoid code duplication between prev_frame and next_frame.
652 * frame.c (candidate_frame): New function. Add comment.
653 (prev_frame, next_frame): Use it. Adjust comment.
655 2012-12-06 Eli Zaretskii <eliz@gnu.org>
657 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
658 fails, signal an error instead of continuing with an empty
660 Encode expanded temp file pattern before passing it to mkstemp or
663 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
664 Encode the file name before passing it to dostounix_filename, in
665 case it will downcase it (under w32-downcase-file-names).
668 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
670 Minor call-process cleanups.
671 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
672 at the same time as other platforms, to simplify analysis.
673 No need for fd0_volatile since we have synch_process_fd.
674 Avoid needless emacs_close; arg is always negative.
676 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
678 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
681 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
683 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
684 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
685 and mouse_face_hidden members to a bitfields.
686 * frame.h (struct frame): Remove set-but-not-used space_width member.
687 (FRAME_SPACE_WIDTH): Remove.
688 * nsterm.m, w32term.c, xterm.c: Adjust users.
689 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
690 member. Adjust users. Convert term_initted, delete_in_insert_mode,
691 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
692 members to a bitfields.
694 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
696 Don't let call-process be a zombie factory (Bug#12980).
697 Fixing this bug required some cleanup of the signal-handling code.
698 As a side effect, this change also fixes a longstanding rare race
699 condition whereby Emacs could mistakenly kill unrelated processes,
700 and it fixes a bug where a second C-g does not kill a recalcitrant
701 synchronous process in GNU/Linux and similar platforms.
702 The patch should also fix the last vestiges of Bug#9488,
703 a bug which has mostly been fixed on the trunk by other changes.
704 * callproc.c, process.h (synch_process_alive, synch_process_death)
705 (synch_process_termsig, sync_process_retcode):
706 Remove. All uses removed, to simplify analysis and so that
707 less consing is done inside critical sections.
708 * callproc.c (call_process_exited): Remove. All uses replaced
709 with !synch_process_pid.
710 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
711 These take the role of what used to be in unwind-protect arg.
713 (block_child_signal, unblock_child_signal):
714 New functions, to avoid races that could kill innocent-victim processes.
715 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
716 (call_process_kill): Record killed processes as deleted, so that
717 zombies do not clutter up the system. Do this inside a critical
718 section, to avoid a race that would allow the clutter.
719 (call_process_cleanup): Fix code so that the second C-g works again
720 on common platforms such as GNU/Linux.
721 (Fcall_process): Create the child process in a critical section,
722 to fix a race condition. If creating an asynchronous process,
723 record it as deleted so that zombies do not clutter up the system.
724 Do unwind-protect for WINDOWSNT too, as that's simpler in the
725 light of these changes. Omit unnecessary call to emacs_close
726 before failure, as the unwind-protect code does that.
727 * callproc.c (call_process_cleanup):
728 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
729 * process.c (record_deleted_pid): New function, containing
730 code refactored out of Fdelete_process.
731 (Fdelete_process): Use it.
732 (process_status_retrieved): Remove. All callers changed to use
734 (record_child_status_change): Remove, folding its contents into ...
735 (handle_child_signal): ... this signal handler. Now, this
736 function is purely a handler for SIGCHLD, and is not called after
737 a synchronous waitpid returns; the synchronous code is moved to
738 wait_for_termination. There is no need to worry about reaping
739 more than one child now.
740 * sysdep.c (get_child_status, child_status_changed): New functions.
741 (wait_for_termination): Now takes int * status and bool
742 interruptible arguments, too. Do not record child status change;
743 that's now the caller's responsibility. All callers changed.
744 Reimplement in terms of get_child_status.
745 (wait_for_termination_1, interruptible_wait_for_termination):
746 Remove. All callers changed to use wait_for_termination.
747 * syswait.h: Include <stdbool.h>, for bool.
748 (record_child_status_change, interruptible_wait_for_termination):
750 (record_deleted_pid, child_status_changed): New decls.
751 (wait_for_termination): Adjust to API changes noted above.
753 * bytecode.c, lisp.h (Qbytecode): Remove.
754 No longer needed after 2012-11-20 interactive-p changes.
756 2012-12-03 Eli Zaretskii <eliz@gnu.org>
758 * xdisp.c (redisplay_window): If the cursor is visible, but inside
759 the scroll margin, move point outside the margin. (Bug#13055)
761 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
763 * gtkutil.c (my_log_handler): New function.
764 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
766 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
768 * lisp.h (modify_region): Rename to...
769 (modify_region_1): ...new prototype.
770 * textprop.c (modify_region): Now static. Adjust users.
771 * insdel.c (modify_region): Rename to...
772 (modify_region_1): ...new function to work with current buffer.
773 Adjust comment and users. Use true and false for booleans.
775 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
777 * alloc.c (free_save_value): New function.
778 (safe_alloca_unwind): Use it.
779 * lisp.h (free_save_value): New prototype.
780 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
782 (save_excursion_restore): Adjust to match saved data structure.
783 Use free_save_value to offload some work from GC. Drop obsolete
786 2012-12-03 Chong Yidong <cyd@gnu.org>
788 * fileio.c (Vauto_save_list_file_name): Doc fix.
790 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
792 * w32fns.c: Remove prototype of atof.
793 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
795 (file_dialog_callback): Make it UINT_PTR.
797 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
800 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
801 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
804 2012-12-03 Glenn Morris <rgm@gnu.org>
806 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
808 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
810 Fix xpalloc confusion after memory is exhausted.
811 * alloc.c (xpalloc): Comment fix.
812 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
813 and signals an error, do not clear charset_table_size, as
814 charset_table is still valid.
815 * doprnt.c (evxprintf): Clear *BUF after freeing it.
817 Use execve to avoid need to munge environ (Bug#13054).
818 * callproc.c (Fcall_process):
819 * process.c (create_process):
820 Don't save and restore environ; no longer needed.
821 * callproc.c (child_setup):
822 Use execve, not execvp, to preserve environ.
824 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
826 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
828 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
830 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
831 display for sliced images (Bug#10500).
833 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
835 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
837 * doc.c (Fdocumentation): Re-add handling of function-documentation,
838 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
840 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
842 * xdisp.c (window_outdated): Remove eassert since it hits
843 some suspicious corner cases (see Bug#13007 and Bug#13012).
844 (mode_line_update_needed): New function.
845 (redisplay_internal, redisplay_window): Use it.
846 (ensure_selected_frame): New function.
847 (redisplay_internal, unwind_redisplay): Use it.
848 (redisplay_internal): Move comment about buffer_shared...
849 (buffer_shared_and_changed): ...near to its real use.
851 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
853 * callproc.c (Fcall_process): Don't misreport vfork failure.
855 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
857 * callproc.c (Fcall_process): Fix vfork portability problems.
858 Do not assume that fd[0], count, filefd, and save_environ survive
859 vfork. Fix bug whereby wrong errno value could be reported for
860 pipe failure. Some minor cleanups, too, as follows. Move buf and
861 bufsize to the context where they're needed. Change new_argv to
862 be of type char **, as this is more convenient and avoids casts.
863 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
864 Now local constants, not macros.
866 2012-11-18 Kenichi Handa <handa@gnu.org>
868 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
869 for the variable "f".
871 2012-11-13 Kenichi Handa <handa@gnu.org>
873 * font.c (font_unparse_xlfd): Exclude special characters from the
874 generating XLFD name.
876 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>

884 Assume EAGAIN and EINTR are defined.
886 * fileio.c (Fcopy_file): Assume EISDIR is defined.
887 * gmalloc.c (ENOMEM, EINVAL): Assume they're defined.
888 * gnutls.c (emacs_gnutls_write): Assume EAGAIN is defined.
889 * lread.c (readbyte_from_file): Assume EINTR is defined.
890 * process.c (wait_reading_process_output, send_process) [subprocesses]:
891 Assume EIO and EAGAIN are defined.
892 * unexcoff.c (write_segment): Assume EFAULT is defined.
894 2012-11-27 Eli Zaretskii <eliz@gnu.org>
896 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
899 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
900 highlighting on the frame was cleared. Prevents assertion
901 violations when repeatedly clicking on the "Top" link of the
902 "bread-crumbs" in Info buffers.
904 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>

914 2012-11-24 Eli Zaretskii <eliz@gnu.org>
916 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
917 between bpos_covered and bpos_max. This fixes cursor display when
918 several display strings follow each other.
920 * .gdbinit (pgx): If the glyph's object is a string, display the
921 pointer to string data, rather than the value of the string object
922 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
924 * indent.c (Fvertical_motion): If the starting position is covered
925 by a display string, return to one position before that, to avoid
926 overshooting it inside move_it_to. (Bug#12930)
928 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
930 * frame.h (struct frame): Remove display_preempted member
931 since all users are dead long ago.

933 * w32menu.c (pending_menu_activation): Remove since not
935 (set_frame_menubar): Adjust user.

937 (struct w32_output): Use bitfields for explicit_parent,
938 asked_for_visible and menubar_active members.
939 Drop unused pending_menu_activation member.
940 * xterm.h (struct x_output): Drop outdated #if 0 code.
941 Use bitfields for explicit_parent, asked_for_visible,
942 has_been_visible and net_wm_state_hidden_seen members.
944 2012-11-23 Eli Zaretskii <eliz@gnu.org>

947 of a literal "/". (Bug#12955)
948 (gl-stamp): Invoke fc.exe directly, not through cmd.
950 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
952 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
953 * dired.c: Assume HAVE_DIRENT_H.
954 (NAMLEN): Remove, replacing with ...
955 (dirent_namelen): New function. All uses changed. Use the GNU macro
956 _D_EXACT_NAMELEN if available, as it's faster than strlen.
957 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
958 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
959 * makefile.w32-in (DIR_H): Remove. All uses replaced with
961 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
962 * ndir.h: Rename to ../nt/inc/dirent.h.
963 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
964 Do not include <dirent.h>; no longer needed.
965 * w32.c: Include <dirent.h> rather than "ndir.h".
967 2012-11-23 Chong Yidong <cyd@gnu.org>
969 * xftfont.c (xftfont_open): Remove duplicate assignment.
971 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
973 * alloc.c (Fgarbage_collect): Unblock input after clearing
974 gc_in_progress to avoid note_mouse_highlight glitch with GC.
975 * frame.h (FRAME_MOUSE_UPDATE): New macro.
976 * msdos.c (IT_frame_up_to_date): Use it here...
977 * w32term.c (w32_frame_up_to_date): ...here...
978 * xterm.c (XTframe_up_to_date): ...and here...
979 * nsterm.m (ns_frame_up_to_date): ...but not here.
980 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
982 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
983 Do not check whether GC is in progress.
985 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
987 * xdisp.c (window_buffer_changed): New function.
988 (update_menu_bar, update_tool_bar): Use it to
989 simplify large 'if' statements.
990 (redisplay_internal): Generalize commonly used
991 'tail' and 'frame' local variables.
993 2012-11-22 Eli Zaretskii <eliz@gnu.org>
995 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
996 with Windows system header.
998 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
1000 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
1001 * alloc.c: Assume unistd.h exists.
1002 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
1003 * sysdep.c (get_current_dir_name): Assume getcwd exists.
1004 (getwd) [USG]: Remove; no longer needed.
1005 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
1006 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
1007 * w32.h (getcwd): Remove decl.
1009 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
1011 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
1012 Make it set selected_window as well.
1013 (update_tool_bar): Use it.
1015 2012-11-21 Ken Brown <kbrown@cornell.edu>
1017 * emacs.c (main): Set the G_SLICE environment variable for all
1018 Cygwin builds, not just GTK builds. See
1019 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
1021 2012-11-21 Eli Zaretskii <eliz@gnu.org>
1023 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1024 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
1025 Define for the MSVC compiler.
1027 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
1029 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
1030 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
1031 dostounix_filename. Prevents crashes down the road, because
1032 dostounix_filename assumes it gets a unibyte string.
1033 Reported by Michel de Ruiter <michel@sentient.nl>, see
1034 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
1036 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>

1040 * lread.c (init_obarray): Set `function' fields to Qnil.
1041 * eval.c (Fcommandp): Ignore Qunbound.
1042 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
1043 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
1044 Test NILP rather than Qunbound.
1045 (Ffmakunbound): Set to Qnil.
1046 (Fsymbol_function): Never signal an error.
1047 (Finteractive_form): Ignore Qunbound.
1049 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
1051 * eval.c (interactive_p): Remove no-longer-used decl.
1053 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
1055 * xdisp.c (buffer_shared): Adjust comment.
1056 (buffer_shared_and_changed): New function.
1057 (prepare_menu_bars, redisplay_internal): Use it to
1058 decide whether all windows or frames should be updated.
1059 (window_outdated): New function.
1060 (text_outside_line_unchanged_p, redisplay_window): Use it.
1061 (redisplay_internal): Likewise. Fix indentation.
1063 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
1065 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
1066 (syms_of_eval): Remove corresponding defsubr.
1067 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
1069 2012-11-19 Daniel Colascione <dancol@dancol.org>
1071 * w32fns.c (Fx_file_dialog):
1072 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
1073 cygwin_convert_file_name*.
1075 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
1076 Rename cygwin_convert_path* to cygwin_convert_file_name*.
1078 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
1080 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
1082 2012-11-18 Eli Zaretskii <eliz@gnu.org>
1084 * w32select.c: Include w32common.h before w32term.h, so that
1085 windows.h gets included before w32term.h uses some of its
1086 features, see below.
1088 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
1090 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
1092 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
1094 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
1096 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
1097 (ns_select): Return at once if events are held (Bug#12834).
1099 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
1101 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
1102 Needed following 2012-10-20 change. (Bug#12902)
1104 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
1106 * w32proc.c (waitpid): Remove unused label get_result.
1108 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
1110 * makefile.w32-in (SYSWAIT_H): New macro.
1111 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
1112 ($(BLD)/sysdep.$(O)): Update dependencies.
1114 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
1116 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
1117 * callproc.c (relocate_fd): Assume F_DUPFD.
1118 * emacs.c, term.c (O_RDWR): Remove.
1119 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
1120 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
1121 * nsterm.m: Assume <fcntl.h> exists.
1122 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
1123 (create_pty, Fmake_network_process, server_accept_connection)
1124 (wait_reading_process_output, init_process_emacs):
1126 (wait_reading_process_output): Put in a special case for WINDOWSNT
1127 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
1128 It's not clear this is needed, but it's a more-conservative change.
1129 (create_process): Assume FD_CLOEXEC.
1130 (create_process, create_pty): Assume O_NOCTTY.
1131 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
1132 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
1133 Omit if not DOS_NT, since F_GETFL is not defined there.
1134 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
1135 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
1137 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
1138 lack it, since gnulib guarantees this.
1139 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
1141 2012-11-17 Eli Zaretskii <eliz@gnu.org>
1143 * w32.c (faccessat): Pretend that directories have the execute bit
1144 set. Emacs expects that, e.g., in files.el:cd-absolute.
1146 * w32proc.c (create_child): Don't clip the PID of the child
1147 process to fit into an Emacs integer, as this is no longer a
1149 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
1150 reaping only the process specified by PID argument, if that is
1151 positive. Use PID instead of dead_child to know which process to
1152 reap. Wait for the child to die only if WNOHANG is not in
1154 (sys_select): Don't set dead_child.
1156 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
1157 as it is no longer needed.
1159 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
1161 (record_child_status_change): Remove the setting of
1162 record_at_most_one_child for the !WNOHANG case.
1164 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
1166 Fix problems in ns port found by static checking.
1167 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
1168 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
1169 not to process group.
1170 (ns_select): Use emacs_write, not write, as that's more robust
1171 in the presence of signals.
1172 (fd_handler:): Check for read errors.
1174 2012-11-16 Glenn Morris <rgm@gnu.org>
1176 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
1178 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
1180 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
1182 2012-11-16 Eli Zaretskii <eliz@gnu.org>
1184 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
1185 use the same value of thread handle.
1186 (start_timer_thread): If the timer thread exited (due to error),
1187 clean up by closing the two handles it used. Duplicate the caller
1188 thread's handle here, so it gets duplicated only once, when
1189 launching the timer thread. Set priority of the timer thread, not
1191 (getitimer): Don't duplicate the caller thread's handle here.
1194 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
1196 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
1199 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
1201 Remove no-longer-used pty_max_bytes variable.
1202 * process.c (pty_max_bytes): Remove; unused.
1203 (send_process): Do not set it.
1205 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
1207 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
1208 Update dependencies.
1210 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
1212 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
1213 This follows up on the 2012-09-29 patch that removed indirection
1214 for the 'function' field. Reported by Sergey Vinokurov in
1215 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
1217 2012-11-14 Eli Zaretskii <eliz@gnu.org>
1219 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
1220 different name, as the MS runtime does not have such a function,
1221 and probably never will.) All callers changed. Ignore DIRFD
1222 value if PATH is an absolute file name, to match Posix spec
1223 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
1226 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
1228 * xdisp.c (echo_area_display, redisplay_internal):
1229 Omit redundant check whether frame_garbaged is set.
1231 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
1233 Use faccessat, not access, when checking file permissions (Bug#12632).
1234 This fixes a bug that has been present in Emacs since its creation.
1235 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
1236 which must set some sort of record. (Torek's bug report was against
1237 a predecessor of GNU Emacs, but GNU Emacs happened to have the
1238 same common flaw.) See Torek's Usenet posting
1239 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
1240 Posted: Fri Apr 8 14:18:56 1983.
1241 * Makefile.in (LIB_EACCESS): New macro.
1243 * callproc.c (init_callproc):
1244 * charset.c (init_charset):
1245 * fileio.c (check_existing, check_executable, check_writable)
1247 * lread.c (openp, load_path_check):
1248 * process.c (allocate_pty):
1250 Use effective UID when checking permissions, not real UID.
1251 * callproc.c (init_callproc):
1252 * charset.c (init_charset):
1253 * lread.c (load_path_check, init_lread):
1254 Test whether directories are accessible, not merely whether they exist.
1255 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
1256 * fileio.c (check_existing, check_executable, check_writable)
1258 Use symbolic names instead of integers for the flags, as they're
1260 (check_writable): New arg AMODE. All uses changed.
1261 Set errno on failure.
1262 (Ffile_readable_p): Use faccessat, not stat + open + close.
1263 (Ffile_writable_p): No need to call check_existing + check_writable.
1264 Just call check_writable and then look at errno. This saves a syscall.
1265 dir should never be nil; replace an unnecessary runtime check
1266 with an eassert. When checking the parent directory of a nonexistent
1267 file, check that the directory is searchable as well as writable, as
1268 we can't create files in unsearchable directories.
1269 (file_directory_p): New function, which uses 'stat' on most platforms
1270 but faccessat with D_OK (for efficiency) if WINDOWSNT.
1271 (Ffile_directory_p, Fset_file_times): Use it.
1272 (file_accessible_directory_p): New function, which uses a single
1273 syscall for efficiency.
1274 (Ffile_accessible_directory_p): Use it.
1275 * xrdb.c (file_p): Use file_directory_p.
1276 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
1277 * lread.c (openp): When opening a file, use fstat rather than
1278 stat, as that avoids a permissions race. When not opening a file,
1279 use file_directory_p rather than stat.
1280 (dir_warning): First arg is now a usage string, not a format.
1281 Use errno. All uses changed.
1282 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
1283 that merely introduced a race.
1284 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
1285 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
1286 and similarly for the other O_* flags.
1287 * w32.c (sys_faccessat): Rename from sys_access and switch to
1288 faccessat's API. All uses changed.
1289 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
1290 (magic_db): Rename from magic_file_p.
1291 (magic_db, search_magic_path): Return an XrmDatabase rather than a
1292 char *, so that we don't have to test for file existence
1293 separately from opening the file for reading. This removes a race
1294 fixes a permission-checking problem, and simplifies the code.
1296 (file_p): Remove; no longer needed.
1298 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
1300 Omit glyphs initialization at startup.
1301 * dispnew.c (glyphs_initialized_initially_p): Remove.
1302 (adjust_frame_glyphs_initially): Likewise. Adjust users.
1303 (Fredraw_frame): Move actual code from here...
1304 (redraw_frame): ...to here. Add eassert. Adjust comment.
1305 (Fredraw_display): Use redraw_frame.
1306 * xdisp.c (clear_garbaged_frames): Likewise.
1308 2012-11-13 Eli Zaretskii <eliz@gnu.org>
1310 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
1311 passed to pint2str and pint2hrstr to be at most the size of the
1312 frame's decode_mode_spec_buffer. This avoids crashes with very
1313 large values of FIELD_WIDTH argument to decode_mode_spec.
1316 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
1318 Fix a race with verify-visited-file-modtime (Bug#12863).
1319 Since at least 1991 Emacs has ignored an mtime difference of no
1320 more than one second, but my guess is that this was to work around
1321 file system bugs that were fixed long ago. Since the race is
1322 causing problems now, let's remove that code.
1323 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
1324 whose time stamp is off by no more than a second. Insist that the
1325 file time stamps match exactly.
1327 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1329 * frame.h (struct frame): Convert external_tool_bar member to
1330 1-bit unsigned bitfield.
1331 * termhooks.h (struct terminal): Remove mouse_moved member since
1332 all users are long dead. Adjust comment on mouse_position_hook.
1334 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1336 Simplify by using FOR_EACH_FRAME here and there.
1337 * frame.c (next_frame, prev_frame, other_visible_frames)
1338 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
1339 * w32term.c (x_window_to_scroll_bar): Likewise.
1340 * window.c (window_list): Likewise.
1341 * xdisp.c (x_consider_frame_title): Likewise.
1342 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
1343 * xfns.c (x_window_to_frame, x_any_window_to_frame)
1344 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
1345 * xmenu.c (menubar_id_to_frame): Likewise.
1346 * xselect.c (frame_for_x_selection): Likewise.
1347 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
1348 (x_window_to_menu_bar): Likewise.
1349 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
1351 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
1353 * data.c (Qdefalias_fset_function): Now static.
1355 Another tweak to vectorlike_header change.
1356 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
1357 Remove, and replace all uses with ...
1358 (next_in_free_list, set_next_in_free_list):
1359 New functions, which respect C's aliasing rules better.
1361 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
1363 * window.c (list4i): Rename from 'quad'. All uses changed.
1364 Needed because <sys/types.h> defines 'quad' on Solaris 10.
1366 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
1368 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
1369 warning about mixing declarations and code in ISO C90.
1371 2012-11-10 Martin Rudalics <rudalics@gmx.at>
1373 * window.c (Fsplit_window_internal): Set combination limit of
1374 new parent window to t iff Vwindow_combination_limit is t;
1375 fixing a regression introduced with the change from 2012-09-22.
1376 (Fset_window_combination_limit): Fix doc-string.
1378 2012-11-10 Eli Zaretskii <eliz@gnu.org>
1380 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
1381 amount when the scroll margins are too large. When scrolling
1382 backwards in the buffer, give up if cannot reach point or the
1383 scroll margin within a reasonable number of screen lines.
1384 Fixes point position in window under scroll-up/down-aggressively when
1385 point is positioned many lines beyond the window top/bottom.
1388 * ralloc.c (relinquish): If real_morecore fails to return memory
1389 to the system, don't crash; instead, leave the last heap
1390 unchanged and return. (Bug#12774)
1392 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1394 * lisp.h (AUTOLOADP): New macro.
1395 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
1396 * data.c (Ffset): Remove special ad-advice-info handling.
1397 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
1399 (Finteractive_form): Simplify.
1400 (Fquo): Don't insist on having at least 2 arguments.
1401 (Qdefalias_fset_function): New var.
1403 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1405 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
1407 * nsfont.m (Qcondensed, Qexpanded): New variables.
1408 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
1409 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
1411 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1413 Fix recently introduced crash on MS-Windows (Bug#12839).
1414 * w32term.h (struct scroll_bar): Use convenient header.
1415 (SCROLL_BAR_VEC_SIZE): Remove.
1416 * w32term.c (x_scroll_bar_create): Use VECSIZE.
1418 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1420 Tweak last vectorlike_header change.
1421 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
1422 vectorlike object on the free list. This is introduced to avoid
1423 some (but not all) pointer casting and aliasing problems, see
1424 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
1425 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
1427 (xvectype, xvecsize): Use them to examine Lisp_Object values.
1429 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1431 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
1432 been removed, so remove them here also.
1434 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1436 * doc.c (Fdocumentation): Handle new property
1437 dynamic-docstring-function to replace the old ad-advice-info.

1452 Use same hash function for hashfn_profiler as for hash_string etc.
1453 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
1454 * lisp.h (sxhash_combine): New inline function, with the contents
1455 of the old SXHASH_COMBINE.
1456 * profiler.c (hashfn_profiler): Use it, instead of having a
1457 special hash function containing a comparison that always yields 1.
1459 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1461 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
1462 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
1463 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
1466 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
1468 * image.c (xpm_make_color_table_h): Fix compiler error because
1469 make_hash_table changed.
1471 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
1473 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
1475 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1477 Use ad-hoc comparison function for the profiler's hash-tables.
1478 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
1479 (make_log): Use them.
1480 (handle_profiler_signal): Don't inhibit quit any longer since we don't
1481 call Fequal any more.

1490 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
1491 (hash_lookup, hash_remove_from_table): Move assertion checking of
1492 hashfn result here. Check hash-equality before calling cmpfn.

1504 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
1505 value of w32-scroll-lock-modifier is neither nil nor one of the
1506 known key modifiers. (Bug#12806)
1508 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
1510 Shrink struct vectorlike_header to the only size field.
1511 * lisp.h (enum pvec_type): Avoid explicit enum member values.
1513 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
1514 PVEC_TYPE_MASK to arrange new bitfield in the vector header.

1516 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
1517 information from the vector header. Adjust comment.

1532 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
1533 (large_vectors): Change type to struct large_vector.
1534 (allocate_vector_from_block): Simplify.
1535 (PSEUDOVECTOR_NBYTES): Replace with...

1538 (allocate_vectorlike): Likewise.
1539 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
1540 Add easserts. Adjust XSETPVECTYPESIZE usage.
1541 (allocate_buffer): Use BUFFER_PVEC_INIT.
1542 (live_vector_p): Adjust to match large vector.
1543 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
1544 * buffer.h (struct buffer): Add next member.
1545 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
1547 (FOR_EACH_BUFFER): Adjust to match struct buffer change.

1555 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
1557 * keyboard.c (event_to_kboard): Do not dereference
1558 frame_or_window field of SELECTION_REQUEST_EVENT
1559 and SELECTION_CLEAR_EVENT events (Bug#12814).
1560 * xterm.h (struct selection_input_event): Adjust comment.
1562 2012-11-07 Eli Zaretskii <eliz@gnu.org>
1564 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
1565 such as Scroll Lock, if the respective keys are treated as
1566 function keys, not as modifiers. This avoids destroying non-ASCII
1567 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
1569 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
1571 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
1573 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1575 Restore some duplicate definitions (Bug#12814).
1576 This undoes part of the 2012-11-03 changes. Some people build
1577 with plain -g rather than with -g3, and they need the duplicate
1578 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
1579 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
1580 Define as macros, as well as as enums or as constants.
1582 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
1584 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
1585 to keypad keys (Bug#12816).
1587 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1589 Minor adjustments of recently-changed frame functions.
1590 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
1591 known to be a frame (we're in the FRAMEP branch).
1592 * lisp.h (Qframep): Remove decl. frame.h declares this.
1593 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
1594 since they're meant for Lisp fixnum values.
1596 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1598 * window.c (Fwindow_combination_limit): Revert to the only
1599 required argument and adjust docstring as suggested in
1600 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
1601 by Martin Rudalics <rudalics@gmx.at>.
1603 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1605 Widely used frame validity and checking functions.
1606 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
1607 * frame.c (decode_live_frame, decode_any_frame): New functions.
1608 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
1609 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
1610 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)

1617 (frame_buffer_list, frame_buffer_predicate): Remove.
1618 * lisp.h (frame_buffer_predicate): Remove prototype.
1619 * buffer.c (Fother_buffer): Use decode_any_frame.
1620 * xdisp.c (Ftool_bar_lines_needed): Likewise.
1621 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
1622 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
1623 (Fclose_font, Ffont_info): Use decode_live_frame.
1624 * fontset.c (check_fontset_name): Likewise.
1625 * terminal.c (Fframe_terminal): Likewise.
1626 * w32fns.c (check_x_frame): Likewise.
1627 * window.c (Fminibuffer_window, Fwindow_at)
1628 (Fcurrent_window_configuration): Likewise.
1629 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
1630 Likewise. Allow zero number of arguments. Adjust docstring.
1631 * dispnew.c (Fredraw_frame): Likewise.
1632 * xfaces.c (frame_or_selected_frame): Remove.
1633 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
1634 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
1635 (Fframe_face_alist): Use decode_live_frame.
1636 * xfns.c (check_x_frame): Likewise.
1638 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1640 * window.c (quad): New function.
1641 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
1642 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
1643 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
1644 (Fwindow_line_height): Use it.
1645 (Fwindow_fringes): Use list3.
1646 (Fwindow_scroll_bars): Use list4.
1647 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
1648 (Fwindow_combination_limit): Allow zero number of arguments.
1650 2012-11-05 Eli Zaretskii <eliz@gnu.org>
1652 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
1654 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
1655 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
1656 file descriptor 2 for standard error. (Bug#12805)
1658 2012-11-05 Chong Yidong <cyd@gnu.org>
1660 * process.c (wait_reading_process_output): Revert previous change.
1662 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
1664 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
1665 This removes code that has been obsolete since around 1990.
1666 * callproc.c (Fcall_process):
1668 * process.c (create_process):
1669 * term.c (dissociate_if_controlling_tty):
1670 Assume setsid exists.
1671 * callproc.c (child_setup): Assume setpgid exists and behaves as
1672 per POSIX.1-1988 or later.
1673 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
1674 * emacs.c (shut_down_emacs):
1675 * sysdep.c (sys_suspend, init_foreground_group):
1676 Assume getpgrp behaves as per POSIX.1-1998 or later.
1677 * msdos.c (setpgrp): Remove.
1678 (tcgetpgrp, setpgid, setsid): New functions.
1679 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
1680 * term.c (no_controlling_tty): Remove; unused.
1681 * w32proc.c (setpgrp): Remove.
1682 (setsid, tcgetpgrp): New functions.
1684 Simplify by assuming __fpending.
1685 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
1686 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
1687 Do not assume that __fpending's result fits in int.
1689 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
1691 Remove EMACS_OUTQSIZE+sleep hack.
1692 * dispnew.c (update_frame_1): Remove hack for terminals slower
1693 than 2400 bps, which throttled Emacs by having it sleep.
1694 This code hasn't worked since at least 2007, when the multi-tty stuff
1695 was added, and anyway those old terminals are long dead.
1696 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
1697 without the dispnew.c change, as dispnew.c doesn't include systty.h.
1699 Fix data-loss with --version (Bug#9574).
1700 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
1701 as we can't assume that emacs_strerror is initialized, and strerror
1702 is good enough here.
1703 (main): Invoke atexit earlier, to catch earlier instances of
1704 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
1706 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
1708 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
1709 (keyDown): Remap keypad keys to X11 virtual key codes.
1711 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
1713 Fix data-loss with --batch (Bug#9574).
1714 * emacs.c: Include <close-stream.h>.
1715 (close_output_streams): New function.
1716 (main): Pass it to atexit, so that Emacs closes stdout and stderr
1717 and handles errors appropriately.
1718 (Fkill_emacs): Don't worry about flushing, as close_output_stream
1721 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
1722 The symptom is a diagnostic "GLib-WARNING **: In call to
1723 g_spawn_sync(), exit status of a child process was requested but
1724 SIGCHLD action was set to SIG_IGN and ECHILD was received by
1725 waitpid(), so exit status can't be returned." The diagnostic
1726 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
1727 The real bug is a race condition between Emacs and glib: Emacs
1728 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
1729 so that glib can't find it. Work around the bug by invoking
1730 waitpid only on subprocesses that Emacs itself creates.
1731 * process.c (create_process, record_child_status_change):
1732 Don't use special value -1 in pid field, as the caller now must
1733 know the pid rather than having the callee infer it.
1734 The inference was sometimes incorrect anyway, due to another race.
1735 (create_process): Set new 'alive' member if child is created.
1736 (process_status_retrieved): New function.
1737 (record_child_status_change): Use it.
1738 Accept negative 1st argument, which means to wait for the
1739 processes that Emacs already knows about. Move special-case code
1740 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
1741 processes that have already been waited for, by testing and
1742 clearing new 'alive' member.
1743 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
1744 now does this internally.
1745 (handle_child_signal): Let record_child_status_change do all
1746 the work, since we do not want to reap all exited child processes,
1747 only the child processes that Emacs itself created.
1748 * process.h (Lisp_Process): New boolean member 'alive'.
1750 Omit duplicate definitions no longer needed with gcc -g3.
1751 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
1752 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
1753 Define only as macros. There's no longer any need to also define
1754 these symbols as enums or as constants, since we now assume
1755 gcc -g3 when debugging.
1757 2012-11-03 Eli Zaretskii <eliz@gnu.org>
1759 * lisp.mk: Adjust comments to the fact that term/internal is now
1760 loaded from loadup.el.
1762 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
1763 (msdos_fatal_signal): New function.
1764 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
1767 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
1768 for GCC versions before 4.
1769 (emacs_raise): Define to call msdos_fatal_signal.
1771 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
1772 iterator when starting in the middle of a display or overlay
1775 2012-11-03 Chong Yidong <cyd@gnu.org>
1777 * process.c (wait_reading_process_output): Clean up the last
1780 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
1782 * process.c (wait_reading_process_output): Avoid a race condition
1783 with SIGIO delivery (Bug#11536).
1785 2012-11-03 Chong Yidong <cyd@gnu.org>
1787 * buffer.c (cursor_type): Untabify docstring.
1789 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1791 * frame.h (struct frame): Drop can_have_scroll_bars member
1792 which is meaningless for a long time. Adjust comments.
1793 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
1794 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
1796 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1798 * window.c (decode_next_window_args): Update window arg after
1799 calling decode_live_window and so fix crash reported at
1800 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
1801 by Juanma Barranquero <lekktu@gmail.com>.
1802 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
1803 * font.c (Ffont_at): Likewise.
1805 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
1807 * widget.c (resize_cb): New function.
1808 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
1809 (EmacsFrameResize): Check if all is up to date before changing frame
1812 2012-11-02 Eli Zaretskii <eliz@gnu.org>
1814 Implement backtrace output for fatal errors on MS-Windows.
1815 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
1816 (BACKTRACE_LIMIT_MAX): New macro.
1817 (w32_backtrace): New function.
1818 (emacs_abort): Use w32_backtrace when the user chooses not to
1819 attach a debugger. Update the text of the abort dialog.
1821 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1823 Window-related stuff cleanup here and there.
1824 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
1825 Use decode_any_window.
1826 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
1827 * xdisp.c (Fformat_mode_line): Likewise.
1828 * font.c (Ffont_at): Use decode_live_window.
1829 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
1830 * window.c (decode_next_window_args): Likewise.
1831 (decode_any_window): Remove static.
1832 * window.h (decode_any_window): Add prototype.
1833 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
1834 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
1837 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1839 Remove pad from struct input_event.
1840 * termhooks.h (struct input_event): Remove padding field.
1842 * keyboard.c (event_to_kboard): Simplify because frame_or_window
1843 member is never cons for a long time. Adjust comment.
1844 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
1845 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
1846 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
1847 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
1849 2012-11-01 Eli Zaretskii <eliz@gnu.org>
1851 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
1853 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
1855 Fix crash when using Emacs as commit editor for git (Bug#12697).
1856 * callproc.c (setpgrp): Remove macro, as we now use setpgid
1857 and it is configured in conf_post.h.
1858 (Fcall_process): Don't invoke both setsid and setpgid; the former
1859 is enough, if it exists.
1860 * callproc.c (Fcall_process, child_setup):
1861 * process.c (create_process): Use setpgid.
1862 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
1864 * dispnew.c (init_display): Initialize the foreground group
1865 if we are running a tty display.
1866 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
1867 * lisp.h (init_foreground_group): New decl.
1868 * sysdep.c (inherited_pgroup): New static var.
1869 (init_foreground_group, tcsetpgrp_without_stopping)

1878 2012-10-31 Martin Rudalics <rudalics@gmx.at>
1880 * minibuf.c (read_minibuf): Restore current buffer since
1881 choose_minibuf_frame calling Fset_frame_selected_window may

1886 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
1888 2012-10-30 Kenichi Handa <handa@gnu.org>
1890 * font.c (Ffont_at): If WINDOW is specified and it is not
1891 displaying the current buffer, signal an error.
1893 2012-10-29 Daniel Colascione <dancol@dancol.org>
1895 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
1896 In preparation for fixing bug#12739, move these functions from
1899 * coding.h, coding.c: ... to here, and compile them only when
1900 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
1901 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
1903 2012-10-28 Eli Zaretskii <eliz@gnu.org>
1905 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
1906 (timer_loop, getitimer, setitimer): Use it instead of

1909 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
1912 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>

1916 (last_appdefined_event): Remove.
1917 (ns_select): Initialize t from last_appdefined_event_data instead
1918 of [last_appdefined_event data1].

1920 remove last_appdefined_event (Bug#12698).
1922 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
1924 * frame.c (x_set_font): Catch internal error.
1926 2012-10-27 Eli Zaretskii <eliz@gnu.org>
1928 Avoid overflow in w32 implementation of interval timers.
1929 When possible, for ITIMER_PROF count only times the main thread
1931 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
1932 'volatile ULONGLONG' types. All the other data which was
1933 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
1934 (GetThreadTimes_Proc): New typedef.
1935 (w32_get_timer_time): New function, returns a suitable time value
1937 (timer_loop): Enter critical section when accessing ULONGLONG
1938 values of the itimer_data struct, as these accesses are no longer
1939 atomic. Call 'w32_get_timer_time' instead of 'clock'.
1940 Remove unused variable.
1941 (init_timers): Initialize s_pfn_Get_Thread_Times.
1942 (start_timer_thread): Don't assign itimer->caller_thread here.

1949 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
1950 mouse movement events if the menu bar is active. This avoids
1951 producing a busy "hour-glass" cursor by Windows if the mouse
1952 pointer is positioned over a tooltip shown for some menu item.
1954 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
1956 Don't assume process IDs fit in int.
1957 * emacs.c (shut_down_emacs) [!DOS_NT]:
1958 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
1959 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
1960 Use pid_t, not int, to store process IDs, as 'int'
1961 is not wide enough on a few platforms (e.g., AIX and IRIX).
1963 2012-10-23 Kenichi Handa <handa@gnu.org>
1965 The following change is to make face-font-rescale-alist work
1966 correctly for non-ASCII fonts.

1984 2012-10-21 Glenn Morris <rgm@gnu.org>
1986 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
1988 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>

1991 * frame.c (Fmouse_position, Fmouse_pixel_position):
1992 * xdisp.c (produce_stretch_glyph):
1993 Declare local vars only when they're needed.
1994 This is clearer and avoids a warning on OpenBSD about unused vars.

1996 This is safer, and avoids OpenBSD warnings about unused vars.
1997 * keyboard.c (record_menu_key): Remove unnecessary decl.
1998 (poll_timer): Define only if POLL_FOR_INPUT is defined.
1999 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
2000 as our definition clashes with OpenBSD's.
2001 * xfaces.c (load_face_colors, check_lface_attrs)
2002 (get_lface_attributes_no_remap, get_lface_attributes)
2003 (lface_fully_specified_p, x_supports_face_attributes_p)
2004 (tty_supports_face_attributes_p, face_fontset, realize_face)
2005 (realize_x_face, realize_tty_face):
2006 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
2007 merely Lisp_Object *. This is more informative and avoids
2008 a warning on OpenBSD about accessing beyond an object's size.
2010 2012-10-20 Chong Yidong <cyd@gnu.org>
2012 * lread.c (Fload): Doc fix (Bug#12592).

2038 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
2039 (staticpro): If we run out of staticpro slots, die with an
2040 informative error instead of just calling emacs_abort.
2042 2012-10-18 Martin Rudalics <rudalics@gmx.at>
2044 Fix two flaws reported by Dmitry Antipov.

2302 the same pointer-to-int (now pointer-to-boolean) &input_pending,

2304 input_pending. All callers changed.
2305 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
2306 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's

2353 'is_tooltip_frame', to avoid confusion with its global namesake.
2355 2012-10-08 Daniel Colascione <dancol@dancol.org>
2357 * xdisp.c (start_hourglass): Call w32_note_current_window when
2358 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
2359 build that caused Emacs to display the hourglass cursor forever.
2361 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
2362 which is broken under remote desktop, calculate the number of
2363 colors available for a display based on the display's number of
2364 planes and number of bits per pixel per plane. (bug#10397).
2366 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
2368 * nsfont.m (Vfonts_in_cache): New variable.
2369 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
2370 are used. Add cached fonts to Vfonts_in_cache.
2371 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
2373 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
2375 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
2377 (FONT_H): Define after FRAME_H.
2378 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
2379 Update dependencies.
2381 * w32term.c: Remove leftover declaration of keyboard_codepage.
2383 2012-10-08 Eli Zaretskii <eliz@gnu.org>
2385 * makefile.w32-in (FONT_H): Add $(FRAME_H).
2386 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
2387 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
2388 (GLOBAL_SOURCES): Add cygw32.c.
2389 ($(BLD)/unexw32.$(O)):
2391 ($(BLD)/w32console.$(O)):
2392 ($(BLD)/w32fns.$(O)):
2393 ($(BLD)/w32heap.$(O)):
2394 ($(BLD)/w32menu.$(O)):
2395 ($(BLD)/w32proc.$(O)): Add w32common.h.
2397 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
2399 (x_to_w32_color): Don't modify the argument, modify a copy instead.
2401 2012-10-08 Daniel Colascione <dancol@dancol.org>
2403 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
2404 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
2405 accidental message numbering hole. Change other messages to
2408 * w32select.h (HAVE_W32SELECT): Remove.
2410 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
2411 w32common.h instead of w32heap.h.
2413 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
2414 (get_allocation_unit, get_processor_type, get_w32_major_version)
2415 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
2416 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
2417 (OS_NT, os_subtype, cache_system_info): Move declarations to
2420 * w32heap.c: Include w32common.h.
2421 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
2422 (w32_minor_version, w32_build_number, w32_subtype):
2423 Remove duplicate definitions.
2425 * w32fns.c: Include w32common.h; include w32heap.h only in
2428 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
2429 Use `report_file_error' instead of `error' in order to better
2430 inform users of what went wrong. Increase NTGUI_UNICODE file
2431 dialog box file name length to 32k, the maximum allowed by the NT
2434 * w32common.h: New file.
2435 (ROUND_UP, ROUND_DOWN, get_page_size)
2436 (get_allocation_unit, get_processor_type, get_w32_major_version)
2437 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
2438 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
2439 (OS_NT, os_subtype, cache_system_info): Move here.
2441 * unexw32.c, unexcw.c: Include w32common.h.
2443 * emacs.c (main): Use (defined (WINDOWSNT) || defined
2444 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
2445 to call syms_of_w32select.
2447 * cygw32.h: Remove obsolete EXFUN declarations.
2449 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
2451 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
2452 of w32inevt.o from SOME_MACHINE_OBJECTS.
2454 2012-10-08 Daniel Colascione <dancol@dancol.org>
2456 * image.c: Permanent fix for JPEG compilation issue --- limit
2457 jpeglib `boolean' redefinition to Cygwin builds.
2459 2012-10-08 Eli Zaretskii <eliz@gnu.org>
2461 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
2463 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
2466 2012-10-08 Daniel Colascione <dancol@dancol.org>
2468 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
2469 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
2470 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
2471 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
2472 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
2473 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
2474 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
2475 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
2476 now a supported configuration.
2478 * Makefile.in: consolidate image variables into LIBIMAGE; add
2479 W32_OBJ and W32_LIBS. Compile new files.
2482 (_DebPrint) declare tracing facility for W32 debugging. We need
2483 to unify tracing later.
2485 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
2486 unconditional use of W32 Unicode functions. Cygwin runs only on
2487 100% Unicode operating systems.
2489 * cygw32.c: New file. Define Cygwin-specific facilities.
2490 (Fcygwin_convert_path_to_windows)
2491 (Fcygwin_convert_path_from_windows): New user functions for
2492 accessing Cygwin path-munging routines.
2494 * cygw32.h: New file.
2495 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
2496 UTF-16LE strings temporarily inside non-Lisp-visible string
2499 (w32_strerror): Just what it says on the tin.
2501 * emacs.c: Make the NS fork-then-exec code for daemon-launching
2502 also run for Cygwin; both systems have the same problem with using
2503 GUI facilities in a forked child. Also call syms_of_cygw32,
2504 syms_of_w32select in correct places.
2506 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
2507 needs fork-then-exec for daemon launching.
2509 * font.h: Include frame.h.
2511 * image.c: Use the image library cache machinery only when we're
2512 compiling for native WINDOWSNT; Cygwin can use shared libraries
2513 like any other Unixlike system.
2515 * keyboard.c: Clarify a comment regarding the input loop.
2517 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
2518 functions directly instead of trying to detect at runtime that our
2519 host operating system supports them. We make this change for two
2520 reasons: Cygwin lacks support for the multibyte character
2521 conversion functions used by the legacy menu code, and Cygwin
2522 never needs to rely on non-Unicode APIs.
2524 * unexw32.c (hinst): Declare extern.
2526 * w32.c: Change header order;
2527 (w32_strerror): Move to w32fns.c because we need it for
2528 non-WINDOWSNT builds.
2530 * w32.h: Add #error macro to make sure we don't include w32.h for
2531 Cygwin builds. Remove w32select declarations.
2533 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
2534 w32fns.c. w32console.c is WINDOWSNT-only.
2536 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
2537 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
2539 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
2540 (w32_major_version, w32_minor_version, w32_build_number)
2541 (os_subtype, sound_type): Define here
2542 (w32_defined_color): Make color parameter const for consistency
2543 with other _defined_color functions.
2544 (w32_createwindow): Unconditionally call w32_init_class instead of
2545 doing so only when hprevinst is non-NULL. Plumbing hprevinst
2546 through the code is complex and unnecessary because class
2547 registration is practically free.
2548 (w32_name_of_message): New EMACSDEBUG-only function.
2549 (Fset_message_beep): Move here
2550 (Fx_open_connection): Require that the display name for Windows be
2551 "w32" for consistency, emacsclient disambiguation, and maybe, one
2552 day, multi-window-system support.
2553 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
2554 Cygwin files for W32 GUI facilities, since these clearly don't
2555 expect Cygwin names.
2556 (_DebPrint): Define.
2557 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
2558 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
2559 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
2560 (w32_last_error): Remove.
2562 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
2564 * w32heap.c (syspage_mask): Declare here.
2565 (cache_system_info): Remove.
2567 * w32inevt.c (faked_key): Define globally, not statically.
2568 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
2569 (w32_console_toggle_lock_key): Move to w32fns.c.
2571 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
2573 * w32proc.c (_DebPrint): Move to w32fns.c.
2574 * w32select.c: Include string.h, stdio.h for Cygwin.
2575 * w32select.h: New File.
2577 * w32term.c: Include io.h for non-CYGWIN builds; needed for
2579 (w32_message_fd): New variable. Under Cygwin, holds the file
2580 descriptor the system used to tell us about pending thread
2583 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
2584 that prevented compilation under non-WINDOWSNT systems.
2586 (w32_initialize): Open /dev/windows and assign it to
2587 w32_message_fd. Provide w32 feature.
2589 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
2590 (WM_EMACS_INPUT_READY): add.
2591 (prepend_msg, w32_message_fd): Declare globally.
2594 (keyboard_handle): Use only when WINDOWSNT.
2595 (notify_msg_ready): New function. Posts a message to the main
2596 thread's message queue under CYGWIN, which wakes up the main
2597 thread from select(2) by making the /dev/windows file descriptor
2598 ready. Under WINDOWSNT, it sets an event the same way the old
2601 (post, prepend_msg): Actually call notify_msg_ready instead of
2602 setting the input event directly.
2604 2012-10-07 Eli Zaretskii <eliz@gnu.org>
2606 * ralloc.c (relinquish): If a heap is ready to be relinquished,
2607 but it still has blocs in it, don't return it to the system,
2608 instead of aborting. (Bug#12402)
2610 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
2612 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
2614 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
2615 MAC_OS_X_VERSION_10_6.
2616 (syms_of_nsterm): Remove comment about Panther and above for
2618 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
2619 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
2620 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
2622 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
2623 MAC_OS_X_VERSION_10_4.
2625 * nsmenu.m (fillWithWidgetValue:): Remove code for <
2626 MAC_OS_X_VERSION_10_2.
2628 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
2630 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
2631 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
2633 * nsterm.m (ns_in_resize): Remove (Bug#12479).
2634 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
2635 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
2636 Remove ns_in_resize check.
2637 (ns_clear_frame_area): Remove resize handle code.
2639 * nsfns.m (ns_in_resize): Remove.
2640 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
2641 Remove ns_in_resize check.
2643 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
2645 Improve sys_siglist detection.
2646 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
2647 defined as a macro, as is done in Solaris.
2648 (sys_siglist_entries): New macro.
2649 (save_strsignal): Use it.
2650 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
2651 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
2653 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
2655 * nsfns.m (Fx_create_frame): Call x_default_parameter with
2656 fullscreen/Fullscreen.
2658 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
2659 tobar_height is new.
2661 * nsterm.m (x_make_frame_visible): Check for fullscreen.
2662 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
2663 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
2664 (windowDidResize:): Check for correct window if old style fullscreen.
2665 Capitalize word in comment. Remove incorrect comment.
2666 (initFrameFromEmacs:): tbar_height renamed tibar_height.
2667 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
2668 error in drawing background.
2669 (toggleFullScreen:): Remove comment. Rearrange calls.
2670 Set toolbar values to zero, save old height in tobar_height.
2671 Restore tool bar height when leaving fullscreen.
2672 (canBecomeMainWindow): New function.
2674 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
2676 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
2678 2012-10-05 Eli Zaretskii <eliz@gnu.org>
2680 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
2682 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
2683 that time stamps of directories could also be changed.
2684 Don't request the too broad GENERIC_WRITE, only the more restrictive
2685 FILE_WRITE_ATTRIBUTES access rights.
2687 * fileio.c (Fset_file_times): Special-case ignoring errors for
2688 directories only on MSDOS, not on MS-Windows.
2690 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
2692 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
2694 2012-10-04 Eli Zaretskii <eliz@gnu.org>
2696 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
2697 see whether CreateFile failed.
2699 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
2701 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
2702 to avoid similar races.
2703 * keyboard.c (pending_signals): Now bool, not int.
2705 Port timers to OpenBSD, plus check for timer failures.
2706 OpenBSD problem reported by Han Boetes.
2707 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
2709 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
2710 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
2711 like OpenBSD, which has timer_settime but does not declare it.
2712 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
2713 whether to use itimerspec-related primitives. All uses of
2714 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
2716 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2718 * profiler.c (handle_profiler_signal): Fix a malloc race
2719 that caused Emacs to hang on Fedora 17 when profiling Lisp.
2721 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
2723 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
2725 2012-10-02 Eli Zaretskii <eliz@gnu.org>
2727 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
2728 consistent with the change in return value of 'safe_strsignal'.
2730 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2732 Prefer plain 'static' to 'static inline' (Bug#12541).
2733 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
2734 (bidi_set_sor_type, bidi_push_embedding_level)
2735 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
2736 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
2737 (bidi_cache_search, bidi_cache_ensure_space)
2738 (bidi_cache_iterator_state, bidi_cache_find)
2739 (bidi_peek_at_next_level, bidi_set_paragraph_end)
2740 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
2741 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
2742 Now 'static', not 'static inline'.
2744 Count overruns when profiling; change units to ns.
2745 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
2746 Give extra weight to samples after overruns, to attempt to count
2747 the time more accurately.
2748 (setup_cpu_timer): Change sampling interval units from ms to ns, since
2749 the underlying primitives nominally do ns.
2750 (Fprofiler_cpu_start): Document the change. Mention that
2751 the sampling intervals are only approximate.
2753 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
2755 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
2757 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
2758 case for the special 0 coding-system.
2760 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
2761 (Fmake_overlay): Remove redundant tests.
2762 (fix_start_end_in_overlays): Remove redundant recentering.
2764 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
2766 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
2767 Update dependencies.
2769 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2771 Fix a malloc race condition involving strsignal.
2772 A signal can arrive in the middle of a malloc, and Emacs's signal
2773 handler can invoke strsignal, which can invoke malloc, which is
2774 not portable. This race condition bug makes Emacs hang on GNU/Linux.
2775 Fix it by altering the signal handler so that it does not invoke
2777 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
2778 * process.c (status_message): Use const pointer, in case strsignal
2779 is #defined to safe_strsignal.
2780 * sysdep.c (sys_siglist, init_signals): Always define and
2781 initialize a substitute sys_siglist if the system does not define
2782 one, even if HAVE_STRSIGNAL.
2783 (safe_strsignal): Rename from strsignal. Always define,
2784 using sys_siglist. Return a const pointer.
2785 * syssignal.h (safe_strsignal): New decl.
2786 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
2788 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2790 * w32proc.c (timer_loop): Fix code that waits for timer
2791 expiration, to avoid high CPU usage.
2793 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
2795 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
2796 (sweep_weak_table): Remove redundant prototypes.
2798 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
2800 * emacs.c: Move the inclusion of TERM_HEADER after including
2801 windows.h on WINDOWSNT. This avoids compilation problems with
2804 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2806 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
2807 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
2808 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
2809 as the previous version used 'void *'.
2811 * ralloc.c (ROUNDUP): Fix last change.
2812 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
2815 * w32proc.c <disable_itimers>: New static flag.
2816 (init_timers): Initialize it to zero, after creating the critical
2817 sections used by the timer threads.
2818 (term_timers): Set to 1 before deleting the critical sections.
2819 (getitimer, setitimer): If disable_itimers is non-zero, return an
2820 error indication without doing anything. Reported by Fabrice
2821 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
2822 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
2824 [!HAVE_SETITIMER]: Behave as the previous version that didn't
2827 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
2828 term_ntproc after all the other bookkeeping, to get timers working
2829 as long as possible.
2831 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2833 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
2834 Suggested by Juri Linkov in
2835 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
2837 Prefer plain 'static' to 'static inline' (Bug#12541).
2838 With static functions, modern compilers inline pretty well by
2839 themselves; advice from programmers often hurts as much as it helps.
2840 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
2841 this change shrinks the text size of the Emacs executable by 1.1%
2842 without affecting CPU significantly in my benchmark.
2843 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

2923 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
2925 Revert the FOLLOW-SYMLINKS change for file-attributes.
2926 Doing it right would require several changes to Tramp, and there's
2927 not enough time to get that tested before the freeze today.
2928 * dired.c (directory_files_internal, Ffile_attributes):
2931 * frame.c (x_report_frame_params): Port better to wider ints.

3136 (handle_profiler_signal): Rename from sigprof_handler_1,
3137 for consistency with other handlers. Do not check whether
3138 cpu_log is a hash-table if garbage collecting, since it

3141 for consistency with other handlers.
3142 (setup_cpu_timer): New function, with much of what used to be in

3144 Prefer timer_settime if available, and prefer
3145 thread cputime clocks, then process cputime clocks, then
3146 monotonic clocks, to the old realtime clock. Use make_timeval
3147 to round more-correctly when falling back to setitimer.
3148 (Fprofiler_cpu_start): Use it.
3149 (Fprofiler_cpu_stop): Prefer timer_settime if available.
3150 Don't assume that passing NULL as the 2nd argument of setitimer
3151 is the same as passing a pointer to all-zero storage.

3153 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
3154 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
3155 non-fatal signal handlers. Ignore SIGPROF on startup.
3156 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
3157 in profiler.c, since sysdep.c now uses it.
3159 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

3215 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
3216 Since this stuff is now private to charset.c, there's no need for
3217 a public macro and no need to inline by hand.

3265 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
3267 Move Vlibrary_cache to emacs.c and reset before dumping.
3269 * lisp.h (reset_image_types): Declare.
3270 [WINDOWSNT] (Vlibrary_cache): Declare.
3272 * image.c (reset_image_types): New function.
3274 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.
3275 (syms_of_emacs) [WINDOWSNT] <Vlibrary_cache>: Initialize and staticpro.
3276 (Fdump_emacs): Reset Vlibrary_cache and image_types.
3278 * w32.c (Vlibrary_cache): Do not define; moved to emacs.c
3279 (globals_of_w32) <Vlibrary_cache>: Do not initialize.
3281 * w32.h (Vlibrary_cache): Do not declare.
3283 2012-09-25 Eli Zaretskii <eliz@gnu.org>
3285 * w32proc.c (sys_signal): Handle all signals defined by the
3286 MS-Windows runtime, not just SIGCHLD. Actually install the signal
3287 handlers for signals supported by Windows. Don't override
3288 term_ntproc as the handler for SIGABRT.
3289 (sigaction): Rewrite to call sys_signal instead of duplicating its
3291 (sys_kill): Improve commentary.
3293 * w32.c (term_ntproc): Accept (and ignore) one argument, for
3294 consistency with a signature of a signal handler. All callers
3296 (init_ntproc): Accept an argument DUMPING. If dumping, don't
3297 install term_ntproc as a signal handler for SIGABRT, as that
3298 should be done by the dumped Emacs.
3300 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
3302 * w32select.c (term_w32select): Protect against repeated
3303 invocation by setting clipboard_owner to NULL after calling
3306 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
3307 and term_ntproc to their modified signatures.
3309 * character.c (char_string, string_char): Remove calls to
3310 MAYBE_UNIFY_CHAR. See the discussion starting at
3311 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
3314 2012-09-25 Chong Yidong <cyd@gnu.org>
3316 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
3318 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
3320 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
3321 when encountering an unknown bytecode.
3323 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
3325 image.c, indent.c: Use bool for booleans.
3326 * dispextern.h (struct image_type): Members valid_p, load, init
3327 now return bool, not int. All uses changed.
3328 * image.c: Omit unnecessary static decls.
3329 (x_create_bitmap_mask, x_build_heuristic_mask):
3330 Return void, not int, since callers don't care about the return value.

3359 Use bool for booleans.
3361 2012-09-24 Chong Yidong <cyd@gnu.org>
3363 * chartab.c (Fset_char_table_default): Obsolete function removed.
3365 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3367 Move pid_t related decls out of lisp.h.
3368 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
3369 (interruptible_wait_for_termination):
3370 Move these decls from lisp.h to syswait.h, since they use pid_t.
3371 Needed on FreeBSD; see Herbert J. Skuhra in
3372 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
3373 * callproc.c: Include syswait.h.

3391 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
3392 * xfns.c (Fx_show_tip) [USE_GTK]:
3393 Use bool for boolean.
3394 * gtkutil.c (xg_update_frame_menubar):
3395 * xmenu.c (update_frame_menubar):
3396 Return void, not int, since caller ignores return value.

3400 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
3402 * makefile.w32-in (BLOCKINPUT_H): Remove.

3419 2012-09-23 Eli Zaretskii <eliz@gnu.org>
3421 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
3422 fatal_error_backtrace.
3424 * w32proc.c (sys_kill): Undo last change: don't do anything when
3425 invoked to deliver SIGABRT to our own process. This is now
3426 handled by emacs_raise.
3428 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
3430 * w32term.c (w32_read_socket): Remove leftover reference to
3431 interrupt_input_pending.
3433 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3435 Do not use SA_NODEFER.
3436 Problem reported by Dani Moncayo in
3437 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
3439 * sysdep.c (emacs_abort): Do not reset signal handler.
3440 * emacs.c (terminate_due_to_signal): Reset signal handler here.
3441 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
3442 wanted even on POSIXish hosts, and it doesn't work on Windows.
3444 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3446 * xterm.c (x_term_init): Call fixup_locale before and after calling
3447 gtk_init (Bug#12392).
3449 2012-09-23 Chong Yidong <cyd@gnu.org>
3451 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
3452 Vdynamic_library_alist.
3454 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
3455 (Fgnutls_available_p): Caller changed.
3457 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
3458 (Flibxml_parse_xml_region): Likewise.
3460 * dispextern.h (struct image_type): Remove arg from init function.
3462 * image.c (Finit_image_library, lookup_image_type)
3463 (define_image_type): Remove now-unneeded second arg.
3464 (init_xpm_functions, init_png_functions, init_jpeg_functions)
3465 (init_tiff_functions, init_gif_functions, init_svg_functions):
3466 Arglist and w32_delayed_load calling convention changed.
3467 (gs_type): Remove init_gs_functions; there is no such function.
3468 (valid_image_p, make_image): Fix caller to lookup_image_type.
3470 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3472 Simplify and avoid signal-handling races (Bug#12471).
3474 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
3475 Avoid recursive loop if there's a fatal error in the function itself.
3476 * atimer.c (pending_atimers):
3477 * blockinput.h: Don't include "atimer.h"; no longer needed.
3478 (interrupt_input_pending): Remove. All uses removed.
3479 pending_signals now counts both atimers and ordinary interrupts.
3480 This is less racy than having three separate pending-signal flags.
3481 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
3483 Rename from their upper-case counterparts BLOCK_INPUT,
3484 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
3485 INPUT_BLOCKED_P, and turn into functions. All uses changed.
3486 This makes it easier to access volatile variables more accurately.
3487 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
3488 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
3489 that's more reliable if the code is buggy and sets
3490 interrupt_input_blocked to a negative value. All uses changed.
3491 * atimer.c (deliver_alarm_signal):
3492 Remove. No need to deliver this to the parent; any thread can
3493 handle this signal now. All uses replaced by underlying handler.
3494 * atimer.c (turn_on_atimers):
3495 * dispnew.c (handle_window_change_signal):
3496 * emacs.c (handle_danger_signal):
3497 * keyboard.c (kbd_buffer_get_event):
3498 Don't reestablish signal handler; not needed with sigaction.
3499 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
3501 Rework to avoid unnecessary accesses to volatile variables.
3502 (UNBLOCK_INPUT_TO): Now a function.
3503 (totally_unblock_input, unblock_input): New decls.
3504 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
3505 (init_data): Remove. Necessary stuff now done in init_signal.
3506 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
3507 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
3508 (fatal_error_code): Remove; no longer needed.
3509 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
3510 it doesn't always backtrace. All uses changed. No need to reset
3511 signal to default, since sigaction and/or die does that for us now.
3512 Use emacs_raise (FOO), not kill (getpid (), FOO).
3513 (main): Check more-accurately whether we're dumping.
3514 Move fatal-error setup to sysdep.c
3515 * floatfns.c: Do not include "syssignal.h"; no longer needed.
3516 * gtkutil.c (xg_get_file_name, xg_get_font):
3517 Remove no-longer-needed signal-mask manipulation.
3518 * keyboard.c, process.c (POLL_FOR_INPUT):
3519 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
3520 * keyboard.c (read_avail_input): Remove.
3521 All uses replaced by gobble_input.
3522 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
3523 (kbd_buffer_store_event_hold, gobble_input):
3524 (record_asynch_buffer_change) [USABLE_SIGIO]:
3525 (store_user_signal_events):
3526 No need to mess with signal mask.
3527 (gobble_input): If blocking input and there are terminals, simply
3528 set pending_signals to 1 and return. All hooks changed to not
3529 worry about whether input is blocked.
3530 (process_pending_signals): Clear pending_signals before processing
3531 them, in case a signal comes in while we're processing.
3532 By convention callers now test pending_signals before calling us.
3533 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
3534 New functions, to support changes to blockinput.h.
3535 (handle_input_available_signal): Now extern.
3536 (reinvoke_input_signal): Remove. All uses replaced by
3538 (quit_count): Now volatile, since a signal handler uses it.
3539 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
3540 All callers changed. Block SIGINT only if not already blocked.
3541 Clear sigmask reliably, even if Fsignal returns, which it can.
3542 Omit unnecessary accesses to volatile var.
3543 (quit_throw_to_read_char): No need to restore sigmask.
3544 * keyboard.c (gobble_input, handle_user_signal):
3545 * process.c (wait_reading_process_output):
3546 Call signal-handling code rather than killing ourselves.
3547 * lisp.h: Include <float.h>, for...
3548 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
3549 (pending_signals): Now volatile.
3550 (syms_of_data): Now const if IEEE floating point.
3551 (handle_input_available_signal) [USABLE_SIGIO]:
3552 (terminate_due_to_signal, record_child_status_change): New decls.
3553 * process.c (create_process): Avoid disaster if memory is exhausted
3554 while we're processing a vfork, by tightening the critical section
3556 (send_process_frame, process_sent_to, handle_pipe_signal)
3557 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
3559 (send_process): No need for setjmp/longjmp any more, since the
3560 SIGPIPE stuff is now gone. Instead, report an error if errno
3562 (record_child_status_change): Now extern. PID and W are now args.
3563 Return void, not bool. All callers changed.
3564 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
3565 Remove. All uses removed. This bug should be fixed now in a
3567 (wait_for_termination_1): Use waitpid rather than sigsuspend,
3568 and record the child status change directly. This avoids the
3569 need to futz with the signal mask.
3570 (process_fatal_action): Move here from emacs.c.
3571 (emacs_sigaction_flags): New function, containing
3572 much of what used to be in emacs_sigaction_init.
3573 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
3574 caught by emacs, to make races less likely.
3575 (deliver_process_signal): Rename from handle_on_main_thread.
3577 (BACKTRACE_LIMIT_MAX): Now at top level.
3578 (thread_backtrace_buffer, threadback_backtrace_pointers):
3580 (deliver_thread_signal, deliver_fatal_thread_signal):
3581 New functions, for more-accurate delivery of thread-specific signals.
3582 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
3583 (deliver_arith_signal): Handle in this thread, not
3584 in the main thread, since it's triggered by this thread.
3585 (maybe_fatal_sig): New function.
3586 (init_signals): New arg DUMPING so that we can be more accurate
3587 about whether we're dumping. Caller changed.
3588 Treat thread-specific signals differently from process-general signals.
3589 Block all signals while handling fatal error; that's safer.
3590 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
3592 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
3593 Ignore SIGPIPE unless batch.
3594 (emacs_backtrace): Output backtrace for the appropriate thread,
3595 which is not necessarily the main thread.
3596 * syssignal.h: Include <stdbool.h>.
3597 (emacs_raise): New macro.
3598 * xterm.c (x_connection_signal): Remove; no longer needed
3599 now that we use sigaction.
3600 (x_connection_closed): No need to mess with sigmask now.
3601 (x_initialize): No need to reset SIGPIPE handler here, since
3602 init_signals does this for us now.
3604 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3606 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
3607 background rect may be larger (Bug#12245).
3609 2012-09-23 Chong Yidong <cyd@gnu.org>
3611 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
3613 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3615 * .gdbinit: Just stop at fatal_error_backtrace.
3616 See Stefan Monnier's request in
3617 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
3618 Remove no-longer-used query of system type.
3620 2012-09-22 Chong Yidong <cyd@gnu.org>
3622 * search.c (Freplace_match): Doc fix (Bug#12325).
3624 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
3626 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
3627 (Fline_end_position): Doc fix.
3629 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
3631 2012-09-22 Chong Yidong <cyd@gnu.org>
3633 * dispextern.h (struct image_type): Add new slot, storing a type
3634 initialization function.
3636 * image.c (define_image_type): Call the image initializer function
3637 if it is defined. Arguments and return value changed.
3638 (valid_image_p, make_image): Callers changed.
3639 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
3640 (gif_type, imagemagick_type, svg_type, gs_type):
3641 Add initialization functions.
3642 (Finit_image_library): Call lookup_image_type.
3643 (CHECK_LIB_AVAILABLE): Macro deleted.
3644 (lookup_image_type): Call define_image_type here, rather than via
3645 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
3646 (syms_of_image): Move define_image_type calls for xbm_type and
3647 pbm_type to lookup_image_type.
3649 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3651 * keyboard.c (timer_check_2): Move calculation of 'timers' and
3652 'idle_timers' from here ...
3653 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
3654 lists, to avoid infloops when the timer does something stupid,
3655 like reinvoke itself with the same or smaller time-out.
3658 2012-09-22 Martin Rudalics <rudalics@gmx.at>
3660 * window.c (Fsplit_window_internal): Handle only Qt value of
3661 Vwindow_combination_limit separately.
3662 (Qtemp_buffer_resize): New symbol.
3663 (Vwindow_combination_limit): New default value.
3666 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3668 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
3669 the new overlay string. (Bug#10159)
3671 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3673 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
3674 or that fprintf is async-signal-safe. POSIX doesn't require
3677 2012-09-22 Chong Yidong <cyd@gnu.org>
3679 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
3682 2012-09-22 Kenichi Handa <handa@gnu.org>
3684 * composite.c (composition_reseat_it): Handle the case that a
3685 grapheme cluster is not covered by a single font (Bug#12352).
3687 2012-09-21 Chong Yidong <cyd@gnu.org>
3689 * image.c (define_image_type): Avoid adding duplicate types to
3690 image_types (Bug#12463). Suggested by Jörg Walter.
3692 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3694 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
3695 (print_load_command_name): Add case LC_DATA_IN_CODE.
3696 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
3698 2012-09-21 Glenn Morris <rgm@gnu.org>
3700 * eval.c (Frun_hook_with_args_until_success)
3701 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
3703 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
3705 * fileio.c (Ffile_selinux_context): Only call freecon when
3706 lgetfilecon succeeded.
3707 (Fset_file_selinux_context): Likewise. (Bug#12444)
3709 2012-09-21 Eli Zaretskii <eliz@gnu.org>
3711 * xdisp.c (try_window_reusing_current_matrix): Under bidi
3712 reordering, locate the cursor by calling set_cursor_from_row; if
3713 that fails, clear the desired glyph matrix before returning a
3714 failure indication to the caller. Fixes leaving garbled display
3715 when fast scrolling with a down-key. (Bug#12403)
3716 (compute_stop_pos_backwards): Fix a typo that caused crashes while
3717 scrolling through multibyte text.
3719 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
3721 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
3722 calling mark_vectorlike since that's the one that marks the window.
3723 (mark_discard_killed_buffers): Mark the final cdr.
3724 * window.h (struct window): Move prev/next_buffers to the
3725 non-standard fields.
3726 * window.c (make_window): Initialize prev/next_buffers manually.
3728 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
3730 Omit unused arg EXPECTED from socket hooks.
3731 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
3732 * nsterm.m (ns_term_init):
3733 * termhooks.h (struct terminal.read_socket_hook):
3734 * w32inevt.c (w32_console_read_socket):
3735 * w32term.c (w32_read_socket):
3736 * xterm.c (XTread_socket):
3737 Omit unused arg EXPECTED. All callers changed.
3738 (store_user_signal_events): Return void, not int, since callers no
3739 longer care about the return value. All uses changed.
3741 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
3743 * w32gui.h (XParseGeometry): Do not declare.
3745 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
3747 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
3748 Ignore 'expected'. See Eli Zaretskii in
3749 <http://bugs.gnu.org/12471#8> (last line).
3751 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
3752 (XParseGeometry): Now static. Substitute extremal values for
3753 values that are out of range.
3755 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
3757 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
3759 * nsfns.m (XParseGeometry): Remove.
3760 (Fx_create_frame): Call x_set_offset to correctly interpret
3761 top_pos in geometry.
3763 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
3764 (Fx_parse_geometry): If there is a space in string, call
3765 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
3767 2012-09-17 Eli Zaretskii <eliz@gnu.org>
3769 * search.c (scan_buffer): Use character positions in calls to
3770 region_cache_forward and region_cache_backward, not byte
3771 positions. (Bug#12196)
3773 * w32term.c (w32_read_socket): Set pending_signals to 1, like
3774 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
3776 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
3777 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
3778 emacs_blocked_malloc, now deleted.
3780 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
3782 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
3783 The workaround was for improving performance on Solaris 2.4, but
3784 is getting in the way now. Emacs will still work if someone is
3785 still running Solaris 2.4 in a museum somewhere; Sun dropped
3786 support for Solaris 2.4 in 2003.
3787 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
3788 * process.c (create_process) [HAVE_WORKING_VFORK]:
3789 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
3790 since Emacs no longer uses vfork on that platform.
3792 2012-09-17 Glenn Morris <rgm@gnu.org>
3794 * emacs.c: Use COPYRIGHT.
3796 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
3798 Remove configure's --without-sync-input option (Bug#12450).
3799 When auditing signal-handling in preparation for cleaning it up,
3800 I found that SYNC_INPUT has race conditions and would be a real
3801 pain to fix. Since it's an undocumented and deprecated
3802 configure-time option, now seems like a good time to remove it.
3803 Also see <http://bugs.gnu.org/11080#16>.
3804 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
3805 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
3806 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3807 (malloc_hysteresis):
3808 (check_depth) [XMALLOC_OVERRUN_CHECK]:
3809 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
3810 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
3811 (dont_register_blocks, bytes_used_when_reconsidered)
3812 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
3813 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
3814 [!SYSTEM_MALLOC && !SYNC_INPUT]:
3815 Remove. All uses removed.
3816 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
3817 implementation, one that depends on whether the new macro
3818 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
3820 * atimer.c (run_timers, handle_alarm_signal):
3821 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
3822 (handle_async_input, process_pending_signals)
3823 (handle_input_available_signal, init_keyboard):
3824 * nsterm.m (ns_read_socket):
3825 * process.c (wait_reading_process_output):
3826 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
3827 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
3829 * xterm.c (XTread_socket):
3831 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
3832 * eval.c (handling_signal): Remove. All uses removed.
3833 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
3834 All uses replaced with the SYNC_INPUT version.
3835 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
3837 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3840 * font.c (Ffont_shape_gstring): Remove unused local.
3842 2012-09-16 Glenn Morris <rgm@gnu.org>
3844 * Makefile.in (clean): No longer run nextstep's clean.
3846 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
3848 (ns-app): Move here from ns.mk, and simplify.
3849 (clean): Simplify nextstep entry.
3850 * ns.mk: Remove file.
3852 2012-09-17 Kenichi Handa <handa@gnu.org>
3854 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
3855 not covert the last few charactes.
3857 2012-09-16 Kenichi Handa <handa@gnu.org>
3859 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
3860 here, but just check the validity of glyphs in the glyph-string.
3862 2012-09-16 Martin Rudalics <rudalics@gmx.at>
3864 * window.c (Fwindow_parameter, Fset_window_parameter):
3865 Accept any window as argument (Bug#12452).
3867 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
3869 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
3870 to ns_term_init to avoid memory leak.
3872 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
3873 explicit retain/release.
3874 (ns_term_init): Only allow one display. Initialize outerpool and
3877 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3879 Port _setjmp fix to POSIXish hosts as well as Microsoft.
3880 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
3881 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
3882 the Microsoft problem in a different way, by altering ../nt/config.nt.
3884 2012-09-15 Eli Zaretskii <eliz@gnu.org>
3899 * w16select.c: Remove inclusion of setjmp.h, as it is now included
3900 by lisp.h. This completes removal of setjmp.h inclusion
3901 erroneously announced in the previous commit. (Bug#12446)
3903 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
3906 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
3907 not defined as a macro. The latter happens on MS-Windows.
3910 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3912 Port better to POSIX hosts lacking _setjmp (Bug#12446).
3913 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
3914 Some instances of '#include <setjmp.h>' removed, if the
3915 only reason for the instance was because "lisp.h" was included.
3916 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
3917 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
3918 and _longjmp with the new symbols. Emacs already uses _setjmp if
3919 available, so this change affects only POSIXish hosts that have
3920 sigsetjmp but not _setjmp, such as some versions of Solaris and
3921 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
3922 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
3923 (png_load_body) [HAVE_PNG]:
3924 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
3925 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
3926 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
3927 since PNG requires jmp_buf. This is the only exception to the
3928 general rule that we now use sys_setjmp and sys_longjmp.
3929 This exception is OK since this code does not change the signal
3930 mask or longjmp out of a signal handler.
3932 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
3934 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3935 Include "syssignal.h", for 'main_thread'.
3937 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
3939 Avoid out-of-range marker position (Bug#12426).
3940 * insdel.c (replace_range, replace_range_2):
3941 Adjust markers before overlays, as suggested by comments.
3942 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
3943 Remove redundant check before calling offset_intervals.
3945 2012-09-14 Martin Rudalics <rudalics@gmx.at>
3947 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
3948 current buffer (Bug#12387).
3950 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
3952 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
3954 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3956 Use a more backwards-compatible timer format (Bug#12430).
3957 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
3958 vector element, not from the 4th, since PSECS is now at the end.
3959 (Fcurrent_idle_time): Doc fix.
3961 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
3963 Function to mark objects and remove killed buffers at once.
3964 * alloc.c (discard_killed_buffers): Rename to ...
3965 (mark_discard_killed buffers) ... new name. Add marking
3966 of remaining objects. Fix comment. Adjust users.
3967 (mark_object): Do not touch frame buffer lists here.
3968 * frame.c (delete_frame): Reset frame buffer lists here.
3970 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3972 Better workaround for GNOME bug when --enable-gcc-warnings.
3973 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
3974 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
3975 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
3977 Simplify SIGIO usage (Bug#12408).
3978 The code that dealt with SIGIO was crufty and confusing, e.g., it
3979 played tricks like "#undef SIGIO" but these tricks were not used
3980 consistently. Simplify mostly by not #undeffing standard symbols,
3981 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
3982 or not as we please) rather than "defined SIGIO" (standard symbol
3983 that we probably shouldn't #undef).
3984 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
3985 Modules that need it can include it.
3986 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
3987 * dispextern.h (ignore_sigio): New decl.
3988 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
3989 unconditionally, since it's now a no-op if !USABLE_SIGIO.
3990 * emacs.c (shut_down_emacs):
3991 * keyboard.c (kbd_buffer_store_event_hold):
3992 Use ignore_sigio rather than invoking 'signal' directly.
3993 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
3995 (FIONREAD, SIGIO): Do not #undef.
3996 (tty_read_avail_input): Use #error rather than a syntax error.
3997 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
3998 for I_PIPE, used by SETUP_SLAVE_PTY.
3999 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
4000 * sysdep.c (croak): Remove; no longer needed. This bit of
4001 temporary code, with Fred N. Fish's comment that it's temporary,
4002 has been in Emacs since at least 1992!
4003 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
4004 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
4005 * syssignal.h (croak): Remove decl.
4006 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
4007 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
4008 now that we're termios-only.
4009 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
4010 * term.c (dissociate_if_controlling_tty): Use #error rather than
4013 Work around GCC and GNOME bugs when --enable-gcc-warnings.
4014 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
4015 to work around GNOME bug 683906.
4016 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
4017 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
4018 This works around GCC bug 54561.
4020 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4022 More fixes for 'volatile' and setjmp/longjmp.
4023 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
4024 * image.c (struct png_load_context) [HAVE_PNG]: New type.
4025 (png_load_body) [HAVE_PNG]:
4026 (jpeg_load_body) [HAVE_JPEG]:
4027 New function, with most of the old parent function's body.
4028 (png_load) [HAVE_PNG]:
4029 (jpeg_load) [HAVE_JPEG]:
4030 Invoke the new function, to avoid longjmp munging our locals.
4031 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
4032 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
4033 longjmp is passed 2, as the C standard doesn't guarantee this.
4034 Instead, store the failure code into mgr->failure_code.
4036 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4038 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
4039 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
4040 (syms_of_keyboard): Remove support for unread-command-char.
4042 2012-09-12 Eli Zaretskii <eliz@gnu.org>
4044 * w32proc.c (sys_kill): If PID is our process ID and the signal is
4045 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
4046 violation. (Bug#12426)
4048 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4050 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
4052 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4054 * eval.c: Add `inhibit-debugger'.
4055 (Qinhibit_debugger): New symbol.
4056 (call_debugger): Bind it instead of Qdebug_on_error.
4057 (maybe_call_debugger): Test Vinhibit_debugger.
4058 (syms_of_eval): Define inhibit-debugger.
4059 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
4060 (syms_of_xdisp): Remove inhibit-debug-on-message.
4062 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4064 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
4065 If a nonvolatile local variable is written before a _longjmp to
4066 the frame containing the variable, and is read after the _longjmp,
4067 the value read is indeterminate. Some local variables of type
4068 'struct handler' and 'struct catchtag' are used in this way, so
4069 mark each of their slots as volatile if the slot can be set before
4070 _longjmp and read afterwards.
4071 * lisp.h (struct handler): var and chosen_clause are now volatile.
4072 (struct catchtag): val, next, and pdlcount are now volatile.
4074 * bidi.c (bidi_push_it, bidi_pop_it):
4075 * fns.c (copy_hash_table):
4076 * image.c (define_image_type):
4077 * keyboard.c (kbd_buffer_store_event_hold):
4078 * process.c (Fprocess_send_eof):
4079 * xfaces.c (x_create_gc) [HAVE_NS]:
4080 * xgselect.c (xg_select):
4081 Prefer assignment to memcpy when either will do.
4083 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
4084 Use pointer-to-a-pointer to simplify and avoid a NILP check each
4085 time an item is removed. No need to mark this function 'inline';
4086 the compiler knows better than we do.
4088 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
4090 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
4091 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
4092 to change_frame_size (Bug#12388).
4093 (windowDidResize:): Pass YES to updateFrameSize.
4095 * nsterm.h: Add delay parameter to updateFrameSize.
4097 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4099 Discard killed buffers from deleted window and frame objects.
4100 This reduces an amount of references to killed buffers and
4101 helps GC to reclaim them faster.
4102 * alloc.c (discard_killed_buffers): New function.
4103 (mark_object): Use it for deleted windows and frames.
4104 (mark_object): If symbol's value is set up for a killed buffer
4105 or deleted frame, restore its global binding.
4106 * data.c (swap_in_global_binding): Add GC notice.
4107 (swap_in_symval_forwarding): Use convenient set_blv_where.
4108 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
4109 * window.h: ... to here.
4111 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4113 Convenient macro to check whether the buffer is live.
4114 * buffer.h (BUFFER_LIVE_P): New macro.
4115 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
4116 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
4118 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4120 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
4121 composition cases (Bug#12364).
4123 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
4124 overhang of succeeding glyphs overlapping box cursor.
4126 * w32term.c (x_draw_glyph_string): Likewise.
4128 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4130 Simplify, document, and port floating-point (Bug#12381).
4131 The porting part of this patch fixes bugs on non-IEEE platforms
4132 with frexp, ldexp, logb.
4133 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
4135 * floatfns.c: Simplify discussion of functions that Emacs doesn't
4136 support, by removing commented-out code and briefly listing the
4137 C89 functions excluded. The commented-out stuff was confusing
4138 maintenance, e.g., we thought we needed cbrt but it was commented out.
4139 (logb): Remove decl; no longer needed.
4140 (isfinite): New macro, if not already supplied.
4141 (isnan): Don't replace any existing macro.
4142 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
4143 are present on all C89 platforms.
4144 (Ffrexp): Do not special-case zero, as frexp does the right thing
4146 (Flogb): Do not use logb, as it doesn't have the desired meaning
4147 on hosts that use non-base-2 floating point. Instead, stick with
4148 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
4149 frexp, to avoid getting an unspecified result.
4151 * xdisp.c (Qinhibit_debug_on_message): Now static.
4153 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
4155 * nsterm.m (ns_update_begin): Set clip path to whole view by using
4156 NSBezierPath (Bug#12131).
4158 2012-09-10 Chong Yidong <cyd@gnu.org>
4160 * fns.c (Fdelq, Fdelete): Doc fix.
4162 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
4164 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
4165 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
4167 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
4169 * lisp.h (make_lisp_ptr): New macro to replace XSET.
4170 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
4173 2012-09-09 Eli Zaretskii <eliz@gnu.org>
4175 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
4176 left fringe if the window has a left margin. This avoids leaving
4177 traces of the cursor because its leftmost pixel is not drawn over.
4179 * dispnew.c (update_window_line): When the left margin area of a
4180 screen line is updated, set the redraw_fringe_bitmaps_p flag of
4181 that screen line. (Bug#12277)
4183 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
4185 Assume C89 or later for math functions (Bug#12381).
4186 This simplifies the code, and makes it a bit smaller and faster,
4187 and (most important) makes it easier to clean up signal handling
4188 since we can stop worring about floating-point exceptions in
4189 library code. That was a problem before C89, but the problem
4190 went away many years ago on all practical Emacs targets.
4191 * data.c, image.c, lread.c, print.c:
4192 Don't include <math.h>; no longer needed.
4193 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
4194 might be autoconfigured, as that never happens.
4196 * doprnt.c (DBL_MAX_10_EXP):
4197 * print.c (DBL_DIG):
4198 Remove. C89 or later always defines these.
4199 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
4200 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
4201 (arith_error, domain_error, domain_error2):
4202 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
4203 no longer needed -- we simply return what C returns. All uses removed.
4204 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
4206 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
4207 Remove. All uses expanded, as these macros are no longer used
4208 more than once and are now more trouble than they're worth.
4209 (Ftan): Use tan, not sin / cos.
4210 (Flogb): Assume C89 frexp.
4211 (fmod_float): Assume C89 fmod.
4212 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
4213 (init_floatfns): Remove. All uses removed.
4215 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4217 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
4218 compositeToPoint for OSX < 10.6 (Bug#12390).
4220 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
4222 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
4223 This produces more-accurate results.
4225 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4227 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
4228 changes (Bug#12088).
4230 2012-09-08 Chong Yidong <cyd@gnu.org>
4232 * syntax.c (Fstring_to_syntax): Doc fix.
4234 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4236 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
4237 in the internal border.
4238 (x_set_window_size): Remove static variables and their usage.
4239 (ns_redraw_scroll_bars): Fix NSTRACE arg.
4240 (ns_after_update_window_line, ns_draw_fringe_bitmap):
4241 Remove fringe/internal border adjustment (Bug#11052).
4242 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
4243 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
4244 (ns_fix_rect_ibw): Remove.
4245 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
4246 (ns_dumpglyphs_box_or_relief): Ditto.
4247 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
4249 (ns_dumpglyphs_image): Ditto.
4250 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
4252 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
4253 their usage. Add fringe_extended_p and its use as in other terms.
4254 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
4255 scroll bar was removed.
4256 (updateFrameSize): New function.
4257 (windowDidResize): Move code to updateFrameSize and call it.
4259 * nsterm.h (EmacsView): Add updateFrameSize.
4261 2012-09-07 Chong Yidong <cyd@gnu.org>
4263 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
4265 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
4267 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4269 More signal-handler cleanup (Bug#12327).
4270 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
4271 Problem introduced when merging patches. Noted by Eli Zaretskii in
4272 <http://bugs.gnu.org/12327#67>.
4273 * floatfns.c: Comment fix.
4274 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
4275 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
4276 and anyway the declaration is harmless even if SIGDANGER is not defined.
4277 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
4278 defined BROKEN_FIONREAD). systty.h formerly did this, but other
4279 source files not surprisingly expected syssignal.h to define, or
4280 not define, SIGIO, and it's cleaner to do it that way, for consistency.
4281 Include <sys/ioctl.h>, for FIONREAD.
4282 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
4283 This eliminates a problem whereby other files mysteriously had
4284 to include "syssignal.h" before including "systty.h" if they
4285 wanted to use "#ifdef SIGIO".
4287 2012-09-07 Eli Zaretskii <eliz@gnu.org>
4289 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
4291 * w32.c (sigemptyset): Empty the set.
4292 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
4294 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
4296 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
4298 * alloc.c (mark_buffer): Revert unsafe marking optimization.
4299 (mark_object): Likewise for frame objects.
4301 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4303 * syssignal.h (handle_on_main_thread): Always declare,
4304 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
4305 This ports to platforms without HAVE_PTHREAD.
4307 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4309 Signal-handler cleanup (Bug#12327).
4310 Emacs's signal handlers were written in the old 4.2BSD style with
4311 sigblock and sigmask and so forth, and this led to some
4312 inefficiencies and confusion. Rewrite these to use
4313 pthread_sigmask etc. without copying signal sets around. Also,
4314 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
4315 'signal', and instead use functions that do not attempt to take
4316 over the system name space. This patch causes Emacs's text
4317 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
4318 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
4319 Do not include <signal.h> or "syssignal.h", as these
4320 modules do not use signals.
4321 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
4322 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
4323 Do not include <signal.h>, as "syssignal.h" does that for us now.
4324 * atimer.c (sigmask_atimers): New function.
4325 (block_atimers, unblock_atimers): New functions,
4326 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
4328 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
4329 no longer needed here.
4330 * emacs.c (main): Inspect existing signal handler with sigaction,
4331 so that there's no need to block and unblock SIGHUP.
4332 * sysdep.c (struct save_signal): New member 'action', replacing
4333 old member 'handler'.
4334 (save_signal_handlers, restore_signal_handlers):
4335 Use sigaction instead of 'signal' to save and restore.
4336 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
4337 New function. All users of 'signal' modified to use set_sighandler
4338 if they're writeonly, and to use sys_signal if they're read+write.
4339 (emacs_sigaction_init, forwarded_signal): New functions.
4340 (sys_signal): Remove. All uses replaced by calls to sigaction
4341 and emacs_sigaction_init, or by direct calls to 'signal'.
4342 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
4343 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
4344 all uses replaced by pthread_sigmask etc. calls.
4345 * syssignal.h: Include <signal.h>.
4346 (emacs_sigaction_init, forwarded_signal): New decls.
4347 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
4348 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
4349 (sigmask, sys_sigmask): Remove; no longer needed.
4350 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
4351 (sigblock, sigunblock, sigfree):
4352 (sigsetmask) [!defined sigsetmask]:
4353 Remove. All uses replaced by pthread_sigmask.
4354 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
4355 no longer need to be replaced, and its typical old uses
4356 are now done via emacs_sigaction_init and sigaction.
4357 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
4358 (sys_sigdel): Remove; unused.
4359 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
4361 2012-09-06 Eli Zaretskii <eliz@gnu.org>
4363 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
4364 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
4366 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4368 Explicitly mark buffer_defaults and buffer_local_symbols.
4369 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
4370 mark_local_symbols here.
4371 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
4372 since special buffers aren't marked here any more.
4373 (allocate_buffer): Chain new buffer with all_buffers here...
4374 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
4376 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
4377 (syms_of_buffer): Remove staticpro of the above.
4378 (init_buffer_once): Set names for buffer_defaults and
4379 buffer_local_symbols.
4381 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4383 Use bool for booleans in font-related modules.
4384 * font.c (font_intern_prop, font_style_to_value)
4385 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
4386 (generate_otf_features, font_check_otf_features, font_check_otf)
4387 (font_match_p, font_list_entities, font_at):
4388 * fontset.c (fontset_id_valid_p, reorder_font_vector
4389 (fontset_find_font, Fset_fontset_font)
4390 (face_suitable_for_char_p) [0]:
4391 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
4392 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
4393 (m17n_flt_initialized, ftfont_shape_by_flt):
4394 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
4395 * nsfont.m (nsfont_draw):
4396 * w32font.c (w32font_draw):
4397 * w32term.c (x_draw_glyphless_glyph_string_foreground):
4398 Use bool for booleans.
4399 * font.h: Adjust to above API changes.
4400 (struct font, struct font_driver, struct font_driver_list):
4401 Use bool for booleans.
4402 (struct font): Remove useless member encoding_type.
4404 * fontset.c, xftfont.c: Omit unnecessary static decls.
4406 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4408 * alloc.c (mark_object): Revert window marking code
4409 since it's unsafe for the Fset_window_configuration.
4411 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4413 Fix race conditions with signal handlers and errno (Bug#12327).
4414 Be more systematic about preserving errno whenever a signal
4415 handler returns, even if it's not in the main thread. Do this by
4416 renaming signal handlers to distinguish between signal delivery
4417 and signal handling. All uses changed.
4418 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
4419 * data.c (deliver_arith_signal): Rename from arith_error.
4420 * dispnew.c (deliver_window_change_signal): Rename from
4421 window_change_signal.
4422 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
4423 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
4424 * keyboard.c (deliver_input_available_signal): Rename from
4425 input_available_signal.
4426 (deliver_user_signal): Rename from handle_user_signal.
4427 (deliver_interrupt_signal): Rename from interrupt_signal.
4428 * process.c (deliver_pipe_signal): Rename from send_process_trap.
4429 (deliver_child_signal): Rename from sigchld_handler.
4430 * atimer.c (handle_alarm_signal):
4431 * data.c (handle_arith_signal):
4432 * dispnew.c (handle_window_change_signal):
4433 * emacs.c (handle_fatal_signal, handle_danger_signal):
4434 * keyboard.c (handle_input_available_signal):
4435 * keyboard.c (handle_user_signal, handle_interrupt_signal):
4436 * process.c (handle_pipe_signal, handle_child_signal):
4437 New functions, with the actual signal-handling code taken from the
4438 original respective signal handlers, sans the sporadic attempts to
4439 preserve errno, since that's now done by handle_on_main_thread.
4440 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
4441 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
4442 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4444 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4445 Move initialization of main_thread to sysdep.c's init_signals.
4446 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
4447 our usage, and simplifies the mainline code.
4448 (record_child_status_change): New static function, as a helper
4449 for handle_child_signal, and with most of the old child handler's
4451 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
4452 (handle_child_signal): Use the above.
4453 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4454 Moved here from emacs.c.
4455 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
4456 code moved here from emacs.c's main function.
4457 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
4458 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
4459 This lets callers save and restore errno properly.
4461 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4463 Remove redundant or unused things here and there.
4464 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
4465 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
4466 * editfns.c (Fcompare_buffer_substrings): Likewise.
4467 * frame.h (struct terminal, struct font_driver_list):
4468 Remove redundant declarations.
4469 * window.h (Qleft, Qright): Likewise.
4471 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4473 Do not mark objects from deleted buffers, windows and frames.
4474 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
4475 (mark_object): Likewise for windows and frames.
4477 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4479 * alloc.c (valid_lisp_object_p): Treat killed buffers,
4480 buffer_defaults and buffer_local_symbols as valid objects.
4481 Return special value to denote them.
4483 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4485 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
4486 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
4487 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
4488 (file_name_absolute_p, Fsubstitute_in_file_name):
4489 (check_executable, check_writable, Ffile_accessible_directory_p)
4490 (Fset_file_selinux_context, Fdefault_file_modes)
4491 (Finsert_file_contents, choose_write_coding_system)
4492 (Fwrite_region, build_annotations, a_write, e_write)
4494 * filelock.c (boot_time_initialized, get_boot_time)
4495 (get_boot_time_1, lock_file_1, within_one_second):
4496 * floatfns.c (in_float):
4497 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
4498 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
4499 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
4500 * lisp.h (struct Lisp_Hash_Table.cmpfn):
4501 * window.c (compare_window_configurations):
4502 Use bool for booleans.
4503 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
4504 (Fdefault_file_modes): Now mode_t, not int, for modes.
4505 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
4506 (internal_delete_file): Now returns void, not a (boolean) int,
4507 since nobody was looking at the return value.
4508 * lisp.h, window.h: Adjust to above API changes.
4510 * xdisp.c (set_message): Simplify and reindent last change.
4512 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
4514 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
4516 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
4518 * eval.c (call_debugger): Make the function non-static so that we
4519 can call it from set_message.
4521 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
4522 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
4524 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4526 Give more-useful info on a fatal error (Bug#12328).
4527 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
4528 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
4529 of doing the work ourselves.
4530 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
4531 do most of the work.
4532 (fatal_error_backtrace): New function, taken from the guts
4533 of the old fatal_error_signal, but with a new option to output
4535 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
4536 info about the signal than just its number.
4537 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
4538 * sysdep.c: Include <execinfo.h>
4539 (emacs_backtrace): New function, taken partly from the previous
4540 code of the 'die' function.
4541 (emacs_abort): Call fatal_error_backtrace rather than abort.
4543 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
4545 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
4546 eager (load-time) macro-expansion.
4547 * lisp.mk (lisp): Add macroexp.
4549 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4551 Simplify redefinition of 'abort' (Bug#12316).
4552 Do not try to redefine the 'abort' function. Instead, redo
4553 the code so that it calls 'emacs_abort' rather than 'abort'.
4554 This removes the need for the NO_ABORT configure-time macro
4555 and makes it easier to change the abort code to do a backtrace.
4556 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
4557 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
4558 Remove; sysdep.c's emacs_abort now takes its place.
4559 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
4560 'abort' changed to use 'emacs_abort'.
4561 * msdos.c (dos_abort) [defined abort]: Remove; not used.
4562 (abort) [!defined abort]: Rename to ...
4563 (emacs_abort): ... new name.
4564 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
4565 the place of the old 'abort' in emacs.c.
4566 * w32.c, w32fns.c (abort): Do not #undef.
4567 * w32.c (emacs_abort): Rename from w32_abort.
4569 2012-09-04 Eli Zaretskii <eliz@gnu.org>
4571 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
4572 offsets[j].dv, since the y axis of the screen coordinates points
4573 down, while the y axis of the font definition coordinates points
4574 up. This fixes display of Arabic diacritics such as KASRA and
4575 KASRATAN. (Bug#11860)
4577 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4579 Be more systematic about _setjmp vs setjmp.
4580 * alloc.c (test_setjmp, mark_stack):
4581 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
4582 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
4583 (png_load, my_error_exit, jpeg_load):
4584 * process.c (send_process_trap, send_process):
4585 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
4586 The underscored versions are up to 30x faster on some hosts.
4587 Formerly, the code used setjmp+longjmp sometimes and
4588 _setjmp+_longjmp at other times, with no particular reason to
4589 prefer setjmp+longjmp.

4626 * msdos.c (fatal_error_in_progress): ... from here.
4627 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
4629 (redisplay_internal, unwind_redisplay): Simply clear
4630 REDISPLAYING_P when unwinding, instead of saving its previous,
4631 always-false value and then restoring it.
4633 Clean up some extern decls.
4634 Mostly, this hoists extern decls out of .c files and into .h files.
4635 That way, we're more likely to catch errors if the interfaces change.
4636 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
4637 declare xg_mark_data.
4638 * dispextern.h (x_frame_parm_handlers):

4658 Remove now-redundant extern decls.
4659 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
4660 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
4662 * xfaces.c: Remove unnecessary static decls.
4663 * xterm.c (updating_frame): Remove decl of nonexistent object.
4665 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
4666 when building globals.h, as the objects that are not built on
4667 this host are not needed to compile C files on this host.

4721 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
4722 more than one grapheme cluster passed to the shaper: compute the
4723 offset adjustment values separately for each cluster. (Bug#11860)
4725 * image.c: Restore mistakenly removed inclusion of w32.h. Without
4726 it, GCC doesn't see prototypes of w32_delayed_load, and complains
4727 about implicit conversions from integer to pointer.
4729 2012-09-01 Daniel Colascione <dancol@dancol.org>
4731 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
4732 system used too early.

4785 window system declarations.
4787 * frame.h: Move common functions here: set_frame_menubar,
4788 x_set_window_size, x_sync, x_get_focus_frame,
4789 x_set_mouse_position, x_set_mouse_pixel_position,
4790 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

4851 * lread.c (init_lread): For out-of-tree builds, only add the
4852 source directory's site-lisp dir to the load-path if it exists,

4876 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
4877 Add window_closed and button_values. Add void as return value for
4878 add(Button|String|Split). addButton takes int instead of Lisp_Object.

5020 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
5021 not a boolean 'int', since callers never look at the return value.
5022 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
5023 * coding.h (decoding_buffer_size, encoding_buffer_size)
5024 (emacs_mule_string_char): Remove unused extern decls.
5025 (struct iso_2022_spec, struct coding_system):
5026 Use 'unsigned int : 1' for boolean fields, since there's more than one.
5027 (struct emacs_mule_spec): Remove unused field 'full_support'.
5028 All initializations removed.
5029 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
5031 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
5033 Fix spare memory change (Bug#12286).
5034 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
5035 (valid_lisp_object_p): Likewise.
5037 2012-08-27 Martin Rudalics <rudalics@gmx.at>
5039 * window.c (Fset_window_configuration): Record any window's old
5040 buffer if it's replaced (see Bug#8789). If the new current
5041 buffer doesn't appear in the selected window, go to its old
5044 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
5046 Special MEM_TYPE_SPARE to denote reserved memory.
5047 * alloc.c (enum mem_type): New memory type.
5048 (refill_memory_reserve): Use new type for spare memory.
5049 This prevents live_cons_p and live_string_p from incorrect
5050 detection of uninitialized objects from spare memory as live.
5052 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
5055 * Makefile.in (.PHONY): versioclean -> versionclean.
5057 Remove unused external symbols.
5058 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
5059 * window.c (Qwindow_valid_p, decode_valid_window):
5060 Now static, not extern.
5061 * data.c (Qinterval): Remove; unused.
5062 (syms_of_data): Do not define 'interval'.
5063 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
5064 * window.h (decode_valid_window):
5067 * character.c, charset.c, chartab.c: Use bool for booleans.
5068 * character.c (lisp_string_width, string_count_byte8)
5069 (string_escape_byte8):
5070 * charset.c (charset_map_loaded, load_charset_map, read_hex):
5071 (load_charset_map_from_file, map_charset_chars)
5072 (Fdefine_charset_internal, define_charset_internal)
5073 (Fdeclare_equiv_charset, find_charsets_in_text)
5074 (Ffind_charset_region, char_charset, Fiso_charset):
5075 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
5076 (sub_char_table_set, sub_char_table_set_range)
5077 (char_table_set_range, optimize_sub_char_table)
5078 (map_sub_char_table):
5079 Use bool for boolean.
5080 * character.c (str_to_unibyte): Omit last boolean argument; it was
5081 always 0. All callers changed.
5082 * character.h, charset.h: Adjust to match previous changes.
5083 * character.h (char_printable_p): Remove decl of nonexistent function.
5084 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
5085 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
5086 are all boolean, so make them single-bit bitfields.
5088 * lisp.h (ASET): Remove attempt to detect side effects.
5089 It was meant to be temporary and it often doesn't work,
5090 because when IDX has side effects the behavior of IDX==IDX
5091 is undefined. See Stefan Monnier in
5092 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
5094 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
5096 * lisp.h (functionp): New function (extracted from Ffunctionp).
5097 (FUNCTIONP): Use it.
5098 * eval.c (Ffunctionp): Use it.
5100 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
5102 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
5103 as that's faster and simpler than static storage. Don't bother
5104 with the g_main_context_query overhead if g_main_context_pending
5105 says no events are pending.
5106 (gfds, gfds_size): Remove these static vars.
5107 (xgselect_initialize): Remove; no longer needed.
5108 All uses and decls removed.
5110 * emacs.c (fatal_error_signal_hook): Remove.
5111 All uses removed. This leftover from old code was always 0.
5113 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
5114 * casefiddle.c (casify_object, casify_region):
5115 * casetab.c (set_case_table):
5116 * category.c, category.h (word_boundary_p):
5117 * category.h (CHAR_HAS_CATEGORY):
5118 Use bool for booleans, instead of int.
5120 2012-08-25 Eli Zaretskii <eliz@gnu.org>
5122 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
5124 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
5126 On assertion failure, print backtrace if available.
5127 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
5128 (die) [ENABLE_CHECKING]: Print a backtrace if available.
5129 * Makefile.in (LIB_EXECINFO): New macro.
5132 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
5133 * bytecode.c (exec_byte_code):
5134 * callint.c (check_mark, Fcall_interactively):
5135 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
5136 (getenv_internal, sync_process_alive, call_process_exited):
5137 * lisp.h (USE_SAFE_ALLOCA):
5138 Use bool for booleans, instead of int.
5139 * lisp.h, process.h: Adjust prototypes to match above changes.
5140 * callint.c (Fcall_interactively): Don't assume the mark's
5141 offset fits in 'int'.
5143 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
5145 * buffer.c, buffer.h: Use bool for boolean.
5146 * buffer.c (reset_buffer_local_variables)
5147 (buffer_lisp_local_variables, Fset_buffer_modified_p)
5148 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
5149 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
5150 (overlay_touches_p, overlay_strings, Foverlay_put)
5151 (report_overlay_modification, call_overlay_mod_hooks):
5152 (mmap_enlarge, mmap_set_vars):
5153 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
5154 Use bool for booleans, instead of int.
5155 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
5156 since the 1-or-0 return value is always ignored anyway.
5157 (mmap_initialized_p):
5158 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
5159 * buffer.h, lisp.h: Adjust prototypes to match above changes.
5161 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5163 * bidi.c: Use bool for boolean.
5164 This is a bit more readable, and makes the text segment of bidi.o
5165 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
5166 Presumably it's faster too.
5167 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
5169 (bidi_cache_find_level_change, bidi_cache_iterator_state)
5170 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
5171 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
5172 (bidi_explicit_dir_char, bidi_level_of_next_char)
5173 (bidi_find_other_level_edge, bidi_move_to_visually_next):
5174 Use bool for booleans, instead of int.
5175 * dispextern.h (bidi_init_it, bidi_paragraph_init)
5176 (bidi_unshelve_cache): Adjust decls to match code.
5178 2012-08-23 Martin Rudalics <rudalics@gmx.at>
5180 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
5183 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5185 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
5186 * atimer.h: Include <stdbool.h>.
5188 2012-08-22 Dan Nicolaescu <dann@gnu.org>
5190 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
5191 compile time tests instead of run time tests on systems that do
5193 (FRAME_MAC_P): Remove leftover from deleted code.
5194 * frame.c (syms_of_frame): Remove leftover from deleted code.
5196 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
5198 * nsterm.m (insertText:): Don't clear modifiers if code is space.
5200 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
5202 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
5203 Otherwise, the compiler complains about (A?B:C) where B is void
5204 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
5205 (fontset_add): Return void, for FONTSET_ADD.
5207 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5209 * alloc.c: Use bool for booleans.
5210 (gc_in_progress, abort_on_gc)
5211 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5212 (dont_register_blocks) [GC_MALLOC_CHECK]:
5213 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
5214 (check_string_bytes, make_specified_string, memory_full)
5215 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
5216 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
5217 (mark_stack, valid_pointer_p, make_pure_string)
5218 (Fgarbage_collect, survives_gc_p, gc_sweep):
5219 Use bool for booleans, instead of int.
5220 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5221 Remove unused local.
5222 * alloc.c (PURE_POINTER_P):
5223 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
5224 * editfns.c (Fformat):
5225 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
5227 * fns.c (sweep_weak_table):
5228 * lisp.h (suppress_checking, push_message, survives_gc_p)
5229 (make_pure_string, gc_in_progress, abort_on_gc):
5230 * lread.c (readchar, read1):
5231 * print.c (Fprin1_to_string):
5232 * xdisp.c (push_message):
5233 Use bool for booleans affected directly or indirectly by
5236 Make recently-introduced setters macros.
5237 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
5238 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
5239 (set_fontset_default, set_fontset_fallback): Rename from their
5240 upper-case counterparts, and make them functions rather than macros.
5241 This is more consistent with the other recently-introduced setters.
5242 These don't need to be inline, since they're local.
5244 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
5246 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
5247 the loop (Bug#12247).
5249 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5251 * lisp.h (vcopy): Use memcpy rather than our own loop.
5252 This fixes a performance regression introduced by the recent
5253 addition of vcopy. This means 'vcopy' will need to be modified
5254 for a copying collector, but that's OK. Also, tighten the
5255 checking in the assertion.
5257 2012-08-21 Eli Zaretskii <eliz@gnu.org>
5259 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
5260 components for RTL text (Bug#11860). Adjust X-OFFSET of each
5261 non-base glyph for the width of the base character, according to
5262 what x_draw_composite_glyph_string_foreground expects.
5263 Generate WADJUST value according to composition_gstring_width's
5264 expectations, to produce correct width of the composed character.
5265 Reverse the sign of the DU offset produced by ScriptPlace.
5267 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5269 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
5271 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
5273 Avoid direct writes to contents member of struct Lisp_Vector.
5274 * lisp.h (vcopy): New function to copy data into vector.
5275 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
5276 * fns.c (Ffillarray): Use ASET.
5277 * keyboard.c (timer_check_2): Use AREF and ASET.
5278 (append_tool_bar_item, Frecent_keys): Use vcopy.
5279 * lread.c (read_vector): Use ASET.
5280 * msdos.c (Frecent_doskeys): Use vcopy.
5281 * xface.c (Finternal_copy_lisp_face): Use vcopy.
5282 (Finternal_merge_in_global_face): Use ASET and vcopy.
5283 * xfont.c (xfont_list_pattern): Likewise.
5285 2012-08-21 Martin Rudalics <rudalics@gmx.at>
5287 * window.c (Fwindow_point): For the selected window always return
5288 the position of its buffer's point.
5289 (Fset_window_point): For the selected window always go in its
5290 buffer to the specified position.
5292 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
5294 Setter macros for fontsets.
5295 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
5296 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
5297 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
5300 2012-08-20 Glenn Morris <rgm@gnu.org>
5302 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
5303 Don't assume that `ln -f' works.
5305 2012-08-20 Eli Zaretskii <eliz@gnu.org>
5307 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
5308 and later about non-assignments with no effect. See discussion at
5309 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
5312 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5314 Inline setter functions for Lisp_Objects slots of struct specbinding.
5315 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
5318 2012-08-20 Martin Rudalics <rudalics@gmx.at>
5320 * window.c (select_window): Always make selected window's buffer
5323 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5325 Use AREF and ASET for docstrings of category tables.
5326 * category.h (CATEGORY_DOCSTRING): Use AREF.
5327 (SET_CATEGORY_DOCSTRING): Use ASET.
5328 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
5330 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5332 Inline setter functions for hash table members.
5333 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
5334 (set_hash_hash, set_hash_index): Rename with _slot suffix.
5335 (set_hash_key_and_value, set_hash_index, set_hash_next)
5336 (set_hash_hash): New functions.
5337 * charset.c, fns.c: Adjust users.
5339 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5341 Inline getter and setter functions for per-buffer values.
5342 * buffer.h (per_buffer_default, set_per_buffer_default)
5343 (per_buffer_value, set_per_buffer_value): New functions.
5344 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
5345 * buffer.c, data.c: Adjust users.
5347 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
5349 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
5351 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
5353 Rely on <config.h> + <unistd.h> to declare 'environ',
5354 as gnulib does this if the system doesn't.
5355 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
5356 Remove declaration. MS-Windows declares it on stdlib.h which is
5357 included by conf_post.h.
5358 * emacs.c (environ) [DOUG_LEA_MALLOC]:
5359 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
5360 * vm-limit.c: Include <unistd.h>, for 'environ'.
5362 * unexaix.c, unexcoff.c: Include "mem-limits.h".
5363 (start_of_data): Remove decl; mem-limits.h provides it.
5365 * xdisp.c (handle_invisible_prop): Make it a bit faster
5366 and avoid a gcc -Wmaybe-uninitialized diagnostic.
5368 2012-08-19 Chong Yidong <cyd@gnu.org>
5370 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
5373 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
5375 * .gdbinit: Use call instead of set when calling a function in the
5378 * data.c (set_internal): Don't use set_blv_found.
5379 (Fkill_local_variable): Likewise.
5381 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
5383 * nsfont.m (ns_ascii_average_width): Ensure the string
5384 ascii_printable is initialized with a null-terminated character
5385 array. Otherwise, it can contain undesired extra characters.
5387 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
5389 port new setting code to Sun C 5.8 2005/10/13
5390 * chartab.c, lisp.h (char_table_set, char_table_set_range):
5391 Return void, not Lisp_Object. Otherwise, the compiler
5392 complains about (A?B:C) where B is void and C is Lisp_Object
5393 when compiling CHAR_TABLE_SET, due to the recent change to
5394 the API of sub_char_table_set_contents.
5396 2012-08-18 Chong Yidong <cyd@gnu.org>
5398 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
5399 for the string case (Bug#3874).
5401 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
5403 * buffer.h (BSET): Remove (Bug#12215).
5404 Replace all uses with calls to new setter functions.

5432 * category.c (bset_category_table):
5433 * syntax.c (bset_syntax_table):
5434 New setter functions.
5436 * process.h (PSET): Remove (Bug#12215).
5437 Replace all uses with calls to new setter functions.
5438 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
5439 (PROCESS_INLINE): New macro.
5440 (pset_childp): New setter function.
5441 (pset_gnutls_cred_type) [HAVE_GNUTLS]: New setter function.
5442 * process.c (PROCESS_INLINE):
5443 Define to EXTERN_INLINE, so that the corresponding functions
5444 are compiled into code.
5445 (pset_buffer, pset_command, pset_decode_coding_system)
5446 (pset_decoding_buf, pset_encode_coding_system)

5448 (pset_plist, pset_sentinel, pset_status, pset_tty_name)
5449 (pset_type, pset_write_queue): New setter functions.
5451 * window.h (WSET): Remove (Bug#12215).
5452 Replace all uses with calls to new setter functions.
5453 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
5454 (WINDOW_INLINE): New macro.

6340 since it's used in non-static inline functions now.
6342 * xfaces.c (face_at_buffer_position, face_for_overlay_string):

6369 (INLINE_HEADER_END): New macros.
6370 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

6395 This how ASET and AREF are supposed to work, and makes
6396 it easier to think about future improvements. See
6397 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
6398 * charset.h (set_charset_attr): New function.

6788 family of Windows, zero otherwise.
6790 * w32inevt.h: Declare w32_console_unicode_input.
6792 * xdisp.c (init_iterator): Don't reference tip_frame in a build

6810 * alloc.c (listn): Fix the order the arguments are consed onto the
6813 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
6814 enumeration constants, as PURE and HEAP are too general, and clash
6815 with other headers and sources, such as gmalloc.c and the
6816 MS-Windows system headers. All users changed.
6818 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
6820 Revert last save_excursion_save and save_excursion_restore changes.
6821 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

6831 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
6833 Improve GDB symbol export (Bug#12036).
6834 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
6835 arms of an 'if', not using conditional expressions; otherwise GDB
6836 complains about the types in the unevaluated arm when the argument
6837 is an integer literal.
6838 (xgetint): Simplify expression.
6839 * alloc.c (gdb_make_enums_visible): New constant. This ports to
6840 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
6841 Zaretskii in <http://bugs.gnu.org/12036#13>.
6842 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
6843 needed now that we have gdb_make_enums_visible.
6844 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
6845 (enum enum_USE_LSB_TAG):
6846 New enum types, packaging up enums that need to be exported to GDB.
6848 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
6850 Utility function to make a list from specified amount of objects.

6864 * xdisp.c (syms_of_xdisp): Likewise.
6865 * xfns.c (syms_of_xfns): Likewise.
6867 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
6869 Fast save_excursion_save and save_excursion_restore.
6870 * lisp.h (struct Lisp_Excursion): New data type.
6871 (PVEC_EXCURSION): New pseudovector type.
6872 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
6873 to deal with it. Adjust comments.
6874 (init_marker, attach_marker): New prototype.
6875 (unchain_marker): Adjust prototype.

6884 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
6886 Fix export of symbols to GDB (Bug#12036).
6887 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
6888 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
6889 emacs.c, as this is a more-suitable home. Had this been done earlier
6890 the fix for 12036 would have avoided some of the problems noted in
6891 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
6892 would have been more obvious.
6893 * emacs.c: Do not include <verify.h>; no longer needed.
6894 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
6895 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
6896 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
6897 Remove; now done in lisp.h.
6898 * lisp.h (PUBLISH_TO_GDB): New macro.
6899 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
6900 (DATA_SEG_BITS): Use it.
6901 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
6902 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
6903 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
6904 not be usable in #if. This simplifies things.
6906 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
6908 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
6910 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
6912 Simplify export of symbols to GDB (Bug#12036).
6913 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
6914 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
6915 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
6916 Adjust to changes in lisp.h and emacs.c, by using
6917 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
6918 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
6919 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
6920 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
6921 instead of gdb_valbits.
6922 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
6923 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
6924 instead of gdb_array_mark_flag.
6925 (xboolvector): Get size from $->size, not $->header.size.
6926 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
6927 (xreload, hook-run, hookpost-run): Remove.
6928 * emacs.c: Include <verify.h>.
6929 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
6930 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
6932 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
6933 (gdb_USE_LSB_TAG): New enum constants.
6934 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
6935 Also define these as enum constants, so they're visible to GDB.
6936 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
6937 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
6938 as constants, so they're visible to GDB.
6939 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
6940 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
6941 Now enum constants, not macros, so they're visible to GDB.
6942 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
6943 more convenient now. All uses changed.
6944 (VALMASK) [USE_LSB_TAG]: Also define in this case.
6945 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
6947 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

6952 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
6954 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
6955 add argument, tune behavior, and adjust all callers.
6957 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
6959 Use typedef for EMACS_INT, EMACS_UINT.
6960 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
6961 than macros. This simplifies debugging in the usual case, since
6962 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
6963 and it allows expressions involving EMACS_INT casts.
6964 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
6966 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
6968 * nsterm.m (ns_read_socket): Return early if there is a modal
6971 2012-07-25 Martin Rudalics <rudalics@gmx.at>

6974 that FOCUS-FRAME can be omitted.
6976 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
6978 Adjust buffer text indirection counters at the end of Fkill_buffer.
6979 * buffer.c (Fkill_buffer): Adjust indirection counters when the
6980 buffer is definitely dead. This should really fix an issue reported
6981 by Christoph Scholtes again. (Bug#12007).
6982 (init_buffer_once): Initialize indirection counters of
6983 buffer_defaults and buffer_local_symbols (for sanity and safety).
6985 2012-07-24 Eli Zaretskii <eliz@gnu.org>
6987 * xdisp.c (init_iterator): Don't compute dimensions of truncation
6988 and continuation glyphs on tooltip frames, leave them at zero.

6991 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
6993 Simplify copy_overlay.
6994 * buffer.c (copy_overlay): Simplify. Use build_marker.

7003 it signals an error when a tooltip frame is being created.
7005 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
7007 Cleanup miscellaneous objects allocation and initialization.
7008 * alloc.c (allocate_misc): Change to static. Add argument to
7009 specify the subtype. Adjust comment and users.

7014 (build_overlay): Add prototype.
7016 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
7018 Swap buffer text indirection counters in Fbuffer_swap_text.
7019 * buffer.c (Fbuffer_swap_text): Swap indirections too.
7020 This avoids crash reported by Christoph Scholtes at
7021 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
7023 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
7025 * nsmenu.m (Popdown_data): New struct.
7026 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
7028 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
7029 (initWithContentRect): Make imgView and contentView non-static
7030 and autorelease them. Also autorelease img and matrix (Bug#12005).
7031 (dealloc): Remove (Bug#12005).
7033 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
7035 Adjust consing_since_gc when objects are explicitly freed.

7048 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
7050 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
7051 as it's limited by the amount of memory, not by INT_MAX.
7053 2012-07-21 Eli Zaretskii <eliz@gnu.org>
7055 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
7056 in special-event-map. See the discussion at
7057 http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00417.html
7060 * w32menu.c (add_menu_item): Cast to ULONG_PTR when assigning
7061 info.dwItemData. Fixes crashes on 64-bit Windows.

7115 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
7116 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
7117 Adjust users accordingly.
7118 * font.h (font_open_by_name): Adjust prototype.
7120 2012-07-20 Dmitry Antipov <dmantipov@yandex.ru>

7136 * buffer.h (FOR_EACH_BUFFER): Rename from 'for_each_buffer'.
7137 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
7138 'for_each_per_buffer_object_at'.
7139 All uses changed. It's better to use upper-case for macros that
7140 cannot be implemented as functions, to give the reader a clue
7141 that they're special.
7143 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>
7145 * alloc.c (Fgarbage_collect): Tweak docstring.

7185 Fix bug that created negative-length intervals.
7186 * intervals.c (merge_interval_right, merge_interval_left):
7187 Do not zero out this interval if it is absorbed by its children,
7188 as this interval's total length doesn't change in that case. See
7189 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00403.html>.
7191 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
7193 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
7194 when invoking (make-bool-vector N t) and N is a positive
7195 multiple of 8 -- the last 8 bits were mistakenly cleared.
7197 Remove some struct layout assumptions in bool vectors.
7198 * alloc.c (bool_header_size): New constant.
7199 (header_size, word_size): Move earlier, as they're now used earlier.
7200 Use 'word_size' in a few more places, where it's appropriate.
7201 (Fmake_bool_vector, sweep_vectors): Don't assume that there is no
7202 padding before the data member of a bool vector.
7203 (sweep_vectors): Use PSEUDOVECTOR_TYPEP, in an eassert, rather
7204 than doing the check by hand with an abort ().
7206 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
7208 * eval.c (Fdefvar): Don't check constants since we only set the var if
7209 it's not yet defined anyway (bug#11904).
7211 * lisp.h (last_undo_boundary): Declare new var.
7212 * keyboard.c (command_loop_1): Set it.
7213 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
7214 were auto-added by the command loop (bug#11774).
7216 2012-07-18 Andreas Schwab <schwab@linux-m68k.org>
7218 * w32font.c (Qsymbol): Remove local definition.

7709 * s/bsd-common.h, s/cygwin.h: No need to undefine INTERRUPT_INPUT,
7710 since nothing has defined it on these platforms.

7724 2012-07-11 John Wiegley <johnw@newartisans.com>
7726 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
7727 function attribute, so we only use it if it exists in the
7730 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
7732 Avoid call to strlen in fast_c_string_match_ignore_case.

7779 * s/aix4-2.h (unix): Remove; no longer needed.
7781 EMACS_TIME simplification (Bug#11875).
7782 This replaces macros (which typically do not work in GDB)
7783 with functions, typedefs and enums, making the code easier to debug.
7784 The functional style also makes code easier to read and maintain.
7785 * systime.h: Include <sys/time.h> on all hosts, not just if
7786 WINDOWSNT, since 'struct timeval' is needed in general.
7787 (EMACS_TIME): Now a typedef, not a macro.
7788 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
7790 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

7799 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
7800 not functions. All uses rewritten to use the following, respectively:
7801 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
7802 (add_emacs_time, sub_emacs_time): New functions.
7803 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
7804 * fileio.c (Fcopy_file):
7805 * xterm.c (XTflash): Get the current time closer to when it's used.
7806 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

7820 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
7821 (menu_separator_name_p):
7822 * nsmenu.m (ns_update_menubar):
7823 Prefer memcmp to strncmp when either will do.
7824 * nsterm.m: Include <ftoastr.h>.
7826 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
7827 Prefer snprintf to strncpy.
7828 * nsterm.m (ns_term_init):
7829 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
7830 * nsterm.m (ns_term_init):
7831 Avoid the need for strncpy, by using build_string or
7832 make_unibyte_string directly. Use dtoastr, not snprintf.
7833 * process.c (Fmake_network_process): Diagnose service names that
7834 are too long, rather than silently truncating them or creating
7835 non-null-terminated names.
7836 (Fnetwork_interface_info): Likewise, for interface names.
7837 * sysdep.c (system_process_attributes) [GNU_LINUX]:
7838 Prefer sprintf to strncat.
7839 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
7840 Prefer vsnprintf to vsprintf + strncpy.
7842 2012-07-10 Glenn Morris <rgm@gnu.org>
7844 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
7845 Clarify fallback case.
7847 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
7849 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
7850 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
7851 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
7852 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
7853 where argument type is known to be a Lisp_Cons.
7855 2012-07-10 Tom Tromey <tromey@redhat.com>
7857 * bytecode.c (BYTE_CODE_THREADED): New macro.

7865 Optimize pure C strings initialization.
7866 * lisp.h (make_pure_string): Fix prototype.
7867 (build_pure_c_string): New function, defined as static inline. This
7868 provides a better opportunity to optimize away calls to strlen when
7869 the function is called with compile-time constant argument.
7870 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
7871 argument, adjust users accordingly. Use build_pure_c_string where
7873 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
7874 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
7875 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
7877 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
7879 Avoid calls to strlen in miscellaneous functions.
7880 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
7881 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
7882 * lread.c (openp): Likewise.
7884 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
7886 Avoid calls to strlen in path processing functions.
7887 * fileio.c (file_name_as_directory): Add comment. Change to add
7888 srclen argument and return the length of result. Adjust users
7890 (directory_file_name): Fix comment. Change to add srclen argument,

7892 Adjust users accordingly.
7893 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
7895 2012-07-10 Glenn Morris <rgm@gnu.org>
7897 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:

7901 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
7902 * s/gnu.h (DATA_START): Move definitions to configure.
7904 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
7905 We include usg5-4-common.h, which defines them both.
7907 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
7908 O_RDONLY already includes it).
7910 Stop ns builds setting the EMACSLOADPATH environment variable.
7911 * nsterm.m (ns_load_path): Rename from ns_init_paths.
7912 Now it does not set EMACSLOADPATH, just returns the load-path string.
7913 * nsterm.h: Update accordingly.
7914 * lread.c [HAVE_NS]: Include nsterm.h.
7915 (init_lread) [HAVE_NS]: Use ns_load_path.
7916 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
7918 2012-07-09 Glenn Morris <rgm@gnu.org>
7920 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
7921 since the included bsd-common.h does so.
7923 Stop ns builds setting the EMACSPATH environment variable.
7924 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
7925 (ns_init_paths): Do not set EMACSPATH.
7926 * nsterm.h (ns_exec_path): Add it.
7927 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
7930 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
7932 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
7934 * process.c (wait_reading_process_output): 'waitchannels' was unset
7935 when read_kbd || !NILP (wait_for_cell); fix this.
7937 Add GCC-style 'const' attribute to functions that can use it.
7938 * character.h (char_resolve_modifier_mask):
7939 * keyboard.h (make_ctrl_char):
7940 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

7949 Add decls with ATTRIBUTE_CONST.
7951 Minor improvements to make_formatted_string.
7952 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
7953 where int is good enough, as vsprintf returns an int.
7954 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
7956 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7958 Use make_formatted_string to avoid double length calculation.
7959 * lisp.h (make_formatted_string): New prototype.
7960 * alloc.c (make_formatted_string): New function.
7961 * buffer.c (Fgenerate_new_buffer_name): Use it.
7962 * dbusbind.c (syms_of_dbusbind): Likewise.
7963 * editfns.c (Fcurrent_time_zone): Likewise.
7964 * filelock.c (get_boot_time): Likewise.
7965 * frame.c (make_terminal_frame, set_term_frame_name)
7966 (x_report_frame_params): Likewise.
7967 * image.c (gs_load): Likewise.
7968 * minibuf.c (get_minibuffer): Likewise.

7983 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7985 Move marker debugging code under MARKER_DEBUG.
7986 * marker.c (MARKER_DEBUG): Move marker debugging code under
7987 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
7988 for bootstrap with --enable-checking (~3x slowdown reported
7989 by Juanma Barranquero <lekktu@gmail.com>).
7990 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
7992 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
7994 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
7995 See <http://bugs.gnu.org/11825#29>.
7997 2012-07-08 Eli Zaretskii <eliz@gnu.org>
7999 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
8000 has no font, use the frame's font. (Bug#11813)
8001 (display_line): Add commentary about displaying truncation glyphs
8003 (produce_special_glyphs): Move here from term.c.
8005 * term.c (produce_special_glyphs): Move to xdisp.c.
8007 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
8010 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
8012 * xdisp.c (display_line): Avoid warning about implicit declaration
8015 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
8017 * lisp.h: Remove empty conditional.
8019 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8021 * lread.c (load_path_check): Now static.
8023 Fix some minor --with-ns problems found by static checking.
8024 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
8025 (x_set_font) [!HAVE_X_WINDOWS]:
8026 * image.c (xpm_load_image) [HAVE_NS]:
8027 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
8028 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
8029 Remove unused local.
8030 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
8031 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
8032 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
8033 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
8034 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
8035 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
8036 Fix pointer signedness problem.
8037 * xfaces.c (FRAME_X_FONT_TABLE):
8038 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
8040 2012-07-07 Glenn Morris <rgm@gnu.org>
8042 * lread.c (load_path_check): New function, split from init_lread.
8043 (init_lread): Reorganize. Motivation:
8044 If EMACSLOADPATH is set, check/warn about that rather than the
8045 defaults, which we are not going to use. Hence we can remove
8046 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
8047 Don't warn if site-lisp directories are missing.
8048 If not installed, start from a blank load-path, since
8049 PATH_LOADSEARCH refers to the eventual installation directories.
8051 2012-07-07 Eli Zaretskii <eliz@gnu.org>
8053 Support truncation and continuation glyphs on GUI frames, when
8054 fringes are disabled. (Bug#11832)
8055 * xdisp.c (init_iterator): Get dimensions of truncation and
8056 continuation glyphs even if on GUI frames.
8057 Adjust it->last_visible_x on GUI frames when the left or right fringes,
8058 or both, are absent.
8059 (start_display, move_it_in_display_line_to): Handle the case of a
8060 GUI frame without a fringe to display continuation or truncation
8062 (insert_left_trunc_glyphs): Support GUI frames: make sure
8063 truncation glyphs overwrite enough glyphs from the current line to
8064 have sufficient space in pixels.
8065 (display_line): Support truncation and continuation glyphs on GUI
8066 frames. If some spare pixels are left on the line after inserting
8067 the truncation glyphs, fill that space with a stretch glyph of a
8068 suitably computed width.
8070 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
8071 produce_glyphs, to support GUI sessions.
8073 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8075 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
8077 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
8079 Do not require float-time's arg to fit in time_t (Bug#11825).
8080 This works better on hosts where time_t is unsigned, and where
8081 float-time is applied to the (negative) difference between two times.
8082 * editfns.c (decode_time_components): Last arg is now double *,
8083 not int *, and means to store all the result as a double, without
8084 worrying about whether the seconds part fits in time_t.
8085 All callers changed.
8086 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
8087 All callers changed.
8088 (Ffloat_time): Do not fail merely because the specified time falls
8089 outside of time_t range.
8091 2012-07-07 Glenn Morris <rgm@gnu.org>
8093 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

8097 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
8099 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
8100 Update dependencies.
8102 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
8104 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8106 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
8107 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
8108 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
8109 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
8110 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
8111 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
8113 * xfont.c (compare_font_names): Redo to omit the need for casts.
8115 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
8117 * xfns.c (Fx_change_window_property): Doc fix.
8118 * w32fns.c (Fx_change_window_property): Doc fix.
8120 * w32fns.c (Fx_window_property): Accept the same arguments as the
8121 X Windows version. Doc fix.
8122 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
8124 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
8125 Eli Zaretskii <eliz@gnu.org>
8127 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.

8129 Obsolete settings removed.
8131 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8133 * process.c: Avoid unnecessary calls to gettime.
8134 (wait_reading_process_output): Don't get the time of day
8135 when gobbling data immediately and not waiting, as there's no need
8136 for it in that case. This removes a FIXME.
8138 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
8140 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
8141 is defined (Bug#11768).

8145 Fix marker debugging code.
8146 * marker.c (byte_char_debug_check): Do not perform the check
8147 if buffer is not multibyte.
8148 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8149 Call byte_char_debug_check with correct arguments.
8151 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8153 Compile marker debugging code only if ENABLE_CHECKING is defined.
8154 * marker.c (byte_char_debug_check, count_markers):
8155 Use only if ENABLE_CHECKING is defined.
8156 (byte_debug_flag): Remove.
8157 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8158 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
8160 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8162 Avoid code repetition in marker-related functions.
8163 * marker.c (attach_marker): New function.

8166 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
8167 Consistently rename charno to charpos.
8168 (marker_position): Add eassert.
8169 (marker_byte_position): Convert to eassert.
8171 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

8181 * lisp.h (build_marker): New prototype.
8182 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
8183 * composite.c (autocmp_chars): Likewise.
8184 * editfns.c (buildmark): Remove.
8185 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
8186 (save_restriction_save): Use build_marker.
8187 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
8188 * window.c (save_window_save): Likewise.
8190 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

8195 (delete_all_overlays, Fdelete_overlay): Use it.
8196 * minibuf.c (get_minibuffer): Fix comment.
8198 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8200 Port to OpenBSD 5.1 amd64.
8201 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
8202 This is needed for OpenBSD, and should be harmless on all BSD systems.
8203 Also, include <sys/sysctl.h>, as it should be available on all
8204 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
8205 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
8206 use p_pid member, not kp_proc.pid.
8208 2012-07-06 Glenn Morris <rgm@gnu.org>
8210 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
8212 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
8214 More xmalloc and related cleanup.
8215 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

8223 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
8225 Omit needless casts involving void * pointers and allocation.
8226 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
8227 as the former is more robust if P's type is changed.
8228 Prefer xzalloc to xmalloc + memset 0.
8229 Simplify malloc-or-realloc to realloc.
8230 Don't worry about xmalloc returning a null pointer.
8231 Prefer xstrdup to xmalloc + strcpy.
8232 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
8234 * keyboard.c (apply_modifiers_uncached): Prefer local array to
8235 alloca of a constant.
8237 2012-07-05 Eli Zaretskii <eliz@gnu.org>
8239 * xdisp.c (display_line): Fix horizontal pixel coordinates when
8240 hscroll is larger than the line width. Fixes long and futile
8241 looping inside extend_face_to_end_of_line (on a TTY) producing
8242 glyphs that are not needed and thrown away.
8244 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
8246 * marker.c (set_marker_restricted_both): Simplify by using
8249 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

8258 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
8259 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
8260 followed by gtk_box_set_homogeneous (Bug#11768).
8261 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
8262 (update_theme_scrollbar_width, xg_create_scroll_bar):
8263 Use gtk_scrollbar_new (Bug#11768).
8264 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
8265 (is_box_type): New function (Bug#11768).
8266 (xg_tool_item_stale_p): Call is_box_type.
8267 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
8268 with default display (Bug#11768).

8272 * xdisp.c (window_hscroll_limited): New function.
8273 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
8274 coordinates when window's hscroll is set to insanely large
8277 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
8279 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

8340 * fileio.c (time_error_value): Check the right error number.
8341 Problem reported by Troels Nielsen in
8342 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
8344 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8346 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
8347 This should be fixed in a better way; see Eli Zaretskii in
8348 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
8349 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
8351 * fileio.c (time_error_value): Rename from special_mtime.
8352 The old name's problems were noted by Eli Zaretskii in
8353 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
8355 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
8356 This variable's comment says Emacs needs at least one GDB-visible
8357 symbol of type enum pvec_type, to work around GDB problems.
8358 The symbol's value doesn't matter.
8360 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
8361 that causes compilation to fail on pre-C99 compilers.
8363 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
8365 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
8366 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
8368 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8370 * buffer.c (init_buffer_once): Fix initialization of
8371 headers for buffer_defaults and buffer_local_symbols.
8372 Reported by Juanma Barranquero <lekktu@gmail.com>.
8374 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
8376 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
8377 * lisp.h (enum pvec_type): Use fewer bits.
8378 (PSEUDOVECTOR_SIZE_BITS): New constant.
8379 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
8380 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
8381 change in pvec_type.
8382 (PSEUDOVECTOR_TYPEP): New macro.

8388 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
8389 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
8390 (sweep_vectors): Use it. Use local var `total_bytes' instead of
8391 abusing vector->header.next.nbytes.
8392 (live_vector_p): Use PVEC_TYPE.
8393 (mark_object): Adapt code to extract pvectype. Use switch.
8395 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8397 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
8398 Tighten new eassert a bit.
8400 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8402 Fix compilation with --enable-gcc-warnings and -O1
8404 * doprnt.c (doprnt): Change type of tem to int, initialize
8405 to avoid compiler warning. Add eassert.
8406 * search.c (simple_search): Initialize match_byte to avoid
8407 compiler warning. Add eassert.
8409 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8411 Avoid weird behavior with large horizontal scrolls.
8412 Without this change, for example, large hscroll values would
8413 mess up Emacs's display on Fedora 15 x86, presumably due to
8414 overflows in int calculations in the display code.
8415 Also, if buffers had long lines, Emacs would freeze.
8416 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
8417 (set_window_hscroll): New function, containing the old guts of
8418 Fset_window_hscroll. Return the clipped value.
8419 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
8420 This avoids the need to check against PTRDIFF_MAX.
8422 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
8424 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8426 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
8428 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8430 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
8431 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
8432 since GCC 4.4.6 issues a bogus warning for them.
8434 Fix bugs in file timestamp newness comparisons.
8435 * fileio.c (Ffile_newer_than_file_p):
8436 * lread.c (Fload): Use full timestamp resolution of files,
8437 not just the 1-second resolution, so that files that are only
8438 slightly newer still count as newer.
8439 * fileio.c (Ffile_newer_than_file_p): Don't assume file
8440 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
8442 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
8444 * fileio.c: Improve handling of file time marker. (Bug#11852)
8445 (special_mtime): New function.
8446 (Finsert_file_contents, Fverify_visited_file_modtime):
8447 Use it to set special mtime values consistently.
8449 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
8451 * fileio.c (Finsert_file_contents): Properly handle st_mtime
8452 marker for non-existing file. (Bug#11852)
8454 2012-07-03 Glenn Morris <rgm@gnu.org>
8456 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
8457 and did not make it into globals.h).
8459 2012-07-03 Tom Tromey <tromey@redhat.com>

8499 * lisp.h (Frandom): Make it visible to C.
8500 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
8501 buffer for invisible buffers. (Bug#1229)

8505 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
8506 values which aren't power of 2.
8507 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
8508 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
8511 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
8513 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.

8519 * alloc.c (allocate_vector_block): Remove redundant
8520 calls to mallopt if DOUG_LEA_MALLOC is defined.
8521 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
8522 avoid calls to mallopt if zero_vector is returned.
8524 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8526 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
8527 is enabled, avoid dereferencing NULL current_sblock if
8530 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8532 Cleanup basic buffer management.
8533 * buffer.h (struct buffer): Change layout to use generic vector
8534 marking code. Fix some comments. Change type of 'clip_changed'
8535 to bitfield. Remove unused #ifndef old.
8536 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
8537 (GET_OVERLAYS_AT): Fix indentation.

8542 * alloc.c (allocate_buffer): Adjust to match new layout of
8543 struct buffer. Fix comment.
8544 (mark_overlay): New function.

8546 Lisp area of struct buffer.
8547 (mark_object): Use it. Adjust marking of misc objects
8548 and related comments.
8550 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
8552 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
8553 wrapper that is not needed because the wrapped code is a no-op (zero
8554 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
8555 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
8557 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
8559 * alloc.c (mark_buffer): Simplify. Remove prototype.
8560 (mark_object): Add comment. Reorganize marking of vector-like
8561 objects. Use CHECK_LIVE for all vector-like objects except buffers
8562 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
8563 Avoid redundant calls to mark_vectorlike for bool vectors.
8565 2012-06-30 Glenn Morris <rgm@gnu.org>
8567 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
8569 * epaths.in (PATH_SITELOADSEARCH): New.
8570 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
8571 This is rather than relying on --enable-locallisppath elements
8572 having "site-lisp" in their names. (Bug#10208#25, 11658)
8574 2012-06-30 Eli Zaretskii <eliz@gnu.org>
8576 * w32proc.c (sys_select): Accept and ignore one more argument.

8585 * process.c (sys_select):
8586 * msdos.c (sys_select): Accept one more argument and ignore it.
8588 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
8589 adapt data types and code to that.
8592 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
8593 which clashes with the gnulib function of the same name.
8595 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
8597 * font.c (font_style_to_value, font_style_symbolic)
8598 (font_prop_validate_style): Add type checks for values in
8601 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
8603 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
8606 2012-06-29 Eli Zaretskii <eliz@gnu.org>
8608 * xdisp.c (try_window_id): Undo last change.
8610 * w32.c (getwd): Adjust commentary about startup_dir.
8611 (init_environment): Always call sys_access, even in non-MSVC
8612 builds. Don't chdir to the directory of the Emacs executable.
8613 This undoes code from 1997 which was justified by the need to
8614 "avoid conflicts when removing and renaming directories". But its
8615 downside was that every relative file name was being interpreted
8616 relative to the directory of the Emacs executable, which can never
8617 be TRT. In particular, it broke sys_access when called with
8618 relative file names.
8619 (sys_access): Map GetLastError to errno.
8621 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8623 * window.h (struct window): Change type of 'fringes_outside_margins'

8668 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
8669 from EMACS_INT to ptrdiff_t.
8670 (make_window): Omit redundant initialization.

8745 * alloc.c (allocate_string): Omit intervals initialization.
8746 * alloc.c (make_uninit_multibyte_string): Initialize intervals

8811 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
8813 Use sprintf return value instead of invoking strlen on result.
8814 In the old days this wasn't portable, since some sprintf
8815 implementations returned char *. But they died out years ago and
8816 Emacs already assumes sprintf returns int.
8817 Similarly for float_to_string.
8818 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

8826 Use sprintf or float_to_string result to avoid need to call strlen.
8827 * data.c (Fnumber_to_string):
8828 Use make_unibyte_string, since the string must be ASCII.
8829 * lisp.h, print.c (float_to_string): Now returns int length.
8830 * term.c (produce_glyphless_glyph):
8831 Use sprintf result rather than recomputing it.
8833 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
8834 * Makefile.in (ALL_CFLAGS):
8835 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

8841 strcasecmp if available.

8864 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
8866 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

8869 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
8871 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
8872 instead of truncating it to 63 (admittedly a generous limit).
8874 * process.c: Fix spelling and caps in comments.

8932 * keyboard.c (kbd_buffer_get_event):
8933 * process.c (Faccept_process_output):
8934 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
8935 This improves on the previous patch, which introduced a bug
8936 when time_t is unsigned and as wide as intmax_t.
8937 See <http://bugs.gnu.org/9000#51>.
8939 2012-06-23 Eli Zaretskii <eliz@gnu.org>

8955 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
8956 Privately reported by Herbert J. Skuhra.
8957 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.

9002 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
9004 Support higher-resolution time stamps (Bug#9000).
9005 The time stamps are only nanosecond-resolution at the C level,
9006 since that's the best that any real-world system supports now.
9007 But they are picosecond-resolution at the Lisp level, as that's
9008 easy, and leaves room for future OS improvements.
9010 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
9013 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
9014 Don't get current time unless it's needed.
9016 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
9017 now provides it if it's absent.
9018 (start_atimer): Port to higher-res time stamps.
9019 Check for time stamp overflow. Don't get current time more
9020 often than is needed.
9022 * buffer.h (struct buffer): Buffer modtime now has high resolution.
9023 Include systime.h, not time.h.
9024 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
9026 * dired.c: Include stat-time.h.
9027 (Ffile-attributes): File times now have higher resolution.
9029 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
9030 (struct image): Timestamp now has higher resolution.
9032 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
9033 has at least microseconds now. All uses removed.
9034 (update_frame, update_single_window, update_window, update_frame_1)
9035 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
9036 (duration_to_sec_usec): Remove; no longer needed.
9038 * editfns.c (time_overflow): Now extern.
9039 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
9040 (float-time, Fformat_time_string, Fcurrent_time_string)
9041 (Fcurrent_time_zone): Accept and generate higher-resolution
9043 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
9044 (decode_time_components, lisp_seconds_argument): New functions.
9045 (make_time): Now static.
9046 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
9047 Report an error if the time is invalid, rather than having the caller
9050 * fileio.c: Include <stat-time.h>
9051 (Fcopy_file): Copy higher-resolution time stamps.
9052 Prefer to set the time stamp via a file descriptor if that works.
9053 (Fset_file_times, Finsert_file_contents, Fwrite_region)
9054 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
9055 (Fvisited_file_modtime, Fset_visited_file_modtime):
9056 Support higher-resolution time stamps.
9058 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
9060 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
9062 * image.c (prepare_image_for_display, clear_image_cache)
9063 (lookup_image): Port to higer-resolution time stamps.
9065 * keyboard.c (start_polling, bind_polling_period):
9066 Check for time stamp overflow.
9067 (read_char, kbd_buffer_get_event, timer_start_idle)
9068 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
9069 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
9070 Port to higher-resolution time stamps. Do not assume time_t is signed.
9071 (decode_timer): New function. Timers are now vectors of length 9,
9072 not 8, to accommodate the picosecond component.
9073 (timer_check_2): Use it.
9075 * nsterm.m (select_timeout, timeval_subtract): Remove.
9076 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
9077 as they're a bit more accurate and handle overflow better.
9078 (ns_select): Change prototype to be compatible with pselect.
9079 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
9080 * nsterm.h (ns_select): Adjust prototype.
9082 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
9083 us-resolution time stamps.
9084 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
9086 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
9088 * lisp.h (time_overflow): New decl.
9089 (wait_reading_process_output): First arg is now intmax_t, not int,
9090 to accommodate larger waits.
9092 * process.h (struct Lisp_Process.read_output_delay):
9093 Now counts nanoseconds, not microseconds.
9094 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about

9097 (wait_reading_process_output):
9098 Port to ns-resolution time stamps.
9099 (Faccept_process_output, wait_reading_process_output):
9100 Check for time stamp overflow. Do not assume time_t is signed.
9101 (select_wrapper): Remove; we now use pselect.
9102 (Fprocess_attributes): Now generates ns-resolution time stamps.
9104 * sysdep.c: Include utimens.h. Don't include utime.h
9105 or worry about struct utimbuf; gnulib does that for us now.
9106 (gettimeofday): Remove; gnulib provides a substitute.
9107 (make_timeval): New function.
9108 (set_file_times): Now sets ns-resolution time stamps.
9109 New arg FD; all uses changed.
9110 (time_from_jiffies, ltime_from_jiffies, get_up_time)

9112 Now returns ns-resolution time stamp. All uses changed.
9113 Check for time stamp overflow.
9115 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
9116 provides a substitute now.
9118 * systime.h: Include timespec.h rather than sys/time.h and time.h,
9119 since it guarantees struct timespec.
9120 (EMACS_TIME): Now struct timespec, so that we can support
9121 ns-resolution time stamps.
9122 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.

9124 (EMACS_USECS): Remove.
9125 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
9126 so multiply the arg by 1000 before storing it.

9136 (make_timeval, make_lisp_time, decode_time_components): New decls.
9137 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
9138 that it mishandled time_t overflow. You can't compare by subtracting!
9139 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
9140 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.

9151 (w32_get_internal_run_time):
9152 Port to higher-resolution Emacs time stamps.
9153 (ltime): Now accepts single 64-bit integer, as that's more convenient

9158 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
9159 for compatibility with pselect. Support ns-resolution time stamps.

9163 * xselect.c (wait_for_property_change, x_get_foreign_selection):
9164 Check for time stamp overflow, and support ns-resolution time stamps.
9166 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
9167 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
9168 (timeval_subtract): Remove; no longer needed.
9169 (XTflash, XTring_bell, x_wait_for_event):
9170 Port to ns-resolution time stamps. Don't assume time_t is signed.

9176 2012-06-22 Eli Zaretskii <eliz@gnu.org>
9178 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
9179 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
9180 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
9181 staticidx goes up to 1597 out of 1600 = 0x640.)
9183 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
9185 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
9186 Otherwise, the umask might be mistakenly 0 while handling input signals.

9196 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
9197 access to `contents' member of Lisp_Vector objects with AREF and ASET
9200 2012-06-19 Chong Yidong <cyd@gnu.org>
9202 * frame.c (delete_frame): When selecting a frame on a different
9203 text terminal, do not alter the terminal's top-frame.

9207 (unwind_format_mode_line): Restore them.
9208 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
9210 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
9211 since tty frames can be explicitly named.
9212 (prepare_menu_bars): Likewise.
9214 * term.c (Ftty_top_frame): New function.
9216 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
9218 Port byte-code-meter to modern targets.
9219 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
9220 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
9221 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
9222 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

9231 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
9232 gets killed during executing of this function (Bug#11665).
9233 Try to always return Qt when the buffer has been actually killed.
9234 (Vkill_buffer_query_functions): In doc-string say that functions
9235 run by this hook should not change the current buffer.
9237 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
9239 Fix recently-introduced process.c problems found by static checking.
9240 * process.c (write_queue_push, write_queue_pop, send_process):

9260 This removes the need for CHECK.
9261 (CHECK): Remove. Its comments about always evaluating its
9262 argument were confusing, as 'eassert' typically does not evaluate
9265 * coding.c (produce_chars): Use ptrdiff_t, not int.
9267 * xterm.c (x_draw_underwave): Check for integer overflow.
9268 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

9561 2012-06-08 Juanma Barranquero <lekktu@gmail.com>
9563 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
9564 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
9566 2012-06-08 Eli Zaretskii <eliz@gnu.org>
9568 * alloc.c (allocate_vectorlike): Fix last change.
9570 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
9572 Block-based vector allocation of small vectors.
9573 * lisp.h (struct vectorlike_header): New field `nbytes',
9574 adjust comment accordingly.
9575 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
9576 to denote vector blocks. Adjust users (live_vector_p,
9577 mark_maybe_pointer, valid_lisp_object_p) accordingly.
9578 (COMMON_MULTIPLE): Move outside #if USE_LSB_TAG.
9579 (VECTOR_BLOCK_SIZE, vroundup, VECTOR_BLOCK_BYTES),
9580 (VBLOCK_BYTES_MIN, VBLOCK_BYTES_MAX, VECTOR_MAX_FREE_LIST_INDEX),
9581 (VECTOR_FREE_LIST_FLAG, ADVANCE, VINDEX, SETUP_ON_FREE_LIST),
9582 (VECTOR_SIZE, VECTOR_IN_BLOCK): New macros.
9583 (roundup_size): New constant.

9597 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
9599 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
9601 * doprnt.c (doprnt): Truncate multibyte char correctly.
9602 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
9603 would mishandle a string argument "Xc" if X was a multibyte
9604 character of length 2: it would truncate after X's first byte
9605 rather than including all of X.
9607 2012-06-06 Chong Yidong <cyd@gnu.org>
9609 * buffer.c (word_wrap): Doc fix.
9611 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

9634 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
9635 (note_mode_line_or_margin_highlight): If there is no help echo,
9636 use mode-line-default-help-echo. Handle the case where the mouse
9637 position is past the end of the mode line string.
9639 * buffer.c (buffer_local_value_1): New function, split from
9640 Fbuffer_local_value; can return Qunbound.

9651 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
9652 and DEFVAR it. Update all users.

9656 * minibuf.c (Fassoc_string): Remove duplicate declaration.
9658 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
9659 Convert pctcpu and pctmem to Lisp float properly.
9660 Let the compiler fold better, as 100.0/0x8000 is exact.
9662 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
9664 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
9667 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
9669 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
9671 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
9673 For a 'struct window', replace some Lisp_Object fields to
9674 bitfields where appropriate, remove unused fields.
9675 * window.h (struct window): Remove unused 'last_mark_x' and
9676 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
9677 change its type from Lisp_Object to bitfield.
9678 Change type of 'force_start', 'optional_new_start',
9679 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
9680 fields from Lisp_Object to bitfield. Adjust users accordingly.
9682 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
9684 Pacify gcc -Wdouble-precision when using Xaw.
9685 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
9686 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
9687 Use 'float' consistently, rather than 'float' in most places
9688 and 'double' in a couple of places.
9690 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9692 * xdisp.c (handle_stop): Detect whether we have overlay strings
9693 loaded by testing it->current.overlay_string_index to be
9694 non-negative, instead of checking whether n_overlay_strings is
9695 positive. (Bug#11587)
9697 2012-05-31 Chong Yidong <cyd@gnu.org>
9699 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
9701 * doc.c (Fsubstitute_command_keys): Doc fix.
9703 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9705 * search.c (search_buffer): Remove calls to
9706 r_alloc_inhibit_buffer_relocation, as it is now called by
9707 maybe_unify_char, which was the cause of relocation of buffer text
9710 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9712 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
9713 for the duration of call to load_charset, to avoid problems with
9714 callers of maybe_unify_char that access buffer text through C
9717 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
9718 decrement the inhibition flag, instead of just setting or
9721 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
9723 Remove obsolete '#define static' cruft.
9724 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
9725 This #undef was "temporary" in 2000; it is no longer needed
9726 now that '#define static' has gone away.
9727 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
9728 (gray_bitmap_bits): Remove; no longer needed.
9729 All uses replaced with definiens.
9730 * xterm.c: Include "bitmaps/gray.xbm".
9732 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
9734 Clean up __executable_start, monstartup when --enable-profiling.
9735 The following changes affect the code only when profiling.
9736 * dispnew.c (__executable_start): Rename from safe_bcopy.
9737 Define only on platforms that need it.
9738 * emacs.c: Include <sys/gmon.h> when profiling.
9739 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
9740 (__executable_start): Remove decl, since lisp.h does it now.
9741 (safe_bcopy): Remove decl; no longer has that name.
9742 (main): Coalesce #if into single bit of code, for simplicity.
9743 Cast pointers to uintptr_t, since standard libraries want integers
9745 * lisp.h (__executable_start): New decl.
9747 2012-05-31 Glenn Morris <rgm@gnu.org>
9749 * image.c (Fimagemagick_types): Doc fix.

9768 * lread.c (read1): Tiny simplification.
9770 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
9772 Do not create empty overlays with the evaporate property (Bug#9642).
9773 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
9774 Bug#9642, but explicitly check that the buffer the overlay would
9775 be moved to is live and rearrange lines to make sure that errors
9776 will not put the overlay in an inconsistent state.
9777 (Fdelete_overlay): Cosmetics.
9779 2012-05-28 Eli Zaretskii <eliz@gnu.org>
9781 * w32term.c (my_bring_window_to_top): New function.
9782 (x_raise_frame): Use handle returned by DeferWindowPos, which
9783 could be different from the original one.
9784 Call my_bring_window_to_top instead of my_set_foreground_window.
9787 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
9788 by calling BringWindowToTop.
9790 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
9791 (WM_EMACS_END): Increase by one.
9793 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
9795 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
9796 This avoids undefined behavior that might cause the eassert
9797 to not catch an out-of-range value.
9799 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
9801 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

9811 when referring to sectname field in printf format.
9813 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
9815 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
9816 Only r_alloc_inhibit_buffer_relocation needed to be added;
9817 the others were already declared.
9819 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
9820 before checking whether it's out of range. Put the check inside
9822 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
9824 2012-05-27 Ken Brown <kbrown@cornell.edu>
9826 * callproc.c (Fcall_process): Restore a line that was accidentally
9827 commented out in the 2011-02-13 change (bug#11547).
9829 2012-05-27 Eli Zaretskii <eliz@gnu.org>
9831 * lisp.h [REL_ALLOC]: Add prototypes for external functions
9832 defined on ralloc.c.
9834 * buffer.c [REL_ALLOC]: Remove prototypes of
9835 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
9836 they are now on lisp.h.
9838 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
9840 * search.c (search_buffer): Use it to inhibit relocation of buffer
9841 text while re_search_2 is doing its job, because re_search_2 is
9842 passed C pointers to buffer text. (Bug#11519)
9844 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
9847 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
9848 state after an additional call to move_it_in_display_line_to, keep
9849 the values of it->max_ascent and it->max_descent found for the
9851 (pos_visible_p): Revert the comparison against bottom_y to what it
9852 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
9855 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
9857 Fix coding-related core dumps with gcc -ftrapv.
9858 The code was computing A - B, where A and B are pointers, and B is
9859 random garbage. This can lead to core dumps on platforms that
9860 have special pointer registers, and it also leads to core dumps on
9861 x86-64 when compiled with gcc -ftrapv. The fix is to compute
9862 A - B only when B is initialized properly.
9863 * coding.c (coding_set_source, coding_set_destination): Return void.
9864 (coding_change_source, coding_change_destinations): New functions,
9865 with the old behaviors of coding_set_source and coding_set_destination.
9866 All callers that need an offset changed to use these new functions.
9868 2012-05-26 Glenn Morris <rgm@gnu.org>
9870 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
9872 2012-05-26 Eli Zaretskii <eliz@gnu.org>
9874 Extend mouse support on W32 text-mode console.
9875 * xdisp.c (draw_row_with_mouse_face):
9876 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
9878 * w32console.c: Include window.h.
9879 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
9881 (initialize_w32_display): Initialize mouse-highlight data.
9883 * w32inevt.c: Include termchar.h and window.h.
9884 (do_mouse_event): Support mouse-autoselect-window. When the mouse
9885 moves, call note_mouse_highlight. If help_echo changed, call
9886 gen_help_event to produce help-echo message in the echo area.
9887 Call clear_mouse_face if mouse_face_hidden is set in the mouse
9890 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
9892 * lread.c (read1): Simplify slightly to avoid an overflow warning
9893 with GCC 4.7.0 on x86-64.
9895 2012-05-26 Eli Zaretskii <eliz@gnu.org>
9897 * bidi.c (bidi_mirror_char): Revert last change: an int is
9898 definitely wide enough here.
9900 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
9902 Fix integer width and related bugs (Bug#9874).

9910 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
9912 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9913 (allocate_pseudovector):
9914 Use int, not EMACS_INT, where int is wide enough.
9915 (inhibit_garbage_collection, Fgarbage_collect):
9916 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9917 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
9918 int might not be wide enough.
9919 (bidi_cache_search, bidi_cache_find, bidi_init_it)
9920 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)

9922 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
9923 (bidi_level_of_next_char, bidi_move_to_visually_next):
9924 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9925 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
9926 (Fkill_buffer, Fset_buffer_major_mode)
9927 (advance_to_char_boundary, Fbuffer_swap_text)
9928 (Fset_buffer_multibyte, overlays_at, overlays_in)
9929 (overlay_touches_p, struct sortvec, record_overlay_string)
9930 (overlay_strings, recenter_overlay_lists)
9931 (adjust_overlays_for_insert, adjust_overlays_for_delete)
9932 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
9933 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
9934 (Foverlay_recenter, last_overlay_modification_hooks_used)
9935 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
9936 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9937 (validate_region): Omit unnecessary test for b <= e,
9938 since that's guaranteed by the previous test.
9939 (adjust_overlays_for_delete): Avoid pos + length overflow.
9940 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
9941 (report_overlay_modification):
9942 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9943 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
9944 Omit pointer cast, which isn't needed anyway, and doesn't work
9945 after the EMACS_INT -> ptrdiff_t change.
9946 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
9947 * buffer.h: Adjust decls to match defn changes elsewhere.
9948 (struct buffer_text, struct buffer):
9949 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9950 Use EMACS_INT, not int, where int might not be wide enough.
9951 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
9952 not int, to avoid needless 32-bit limit on 64-bit hosts.
9953 (exec_byte_code): Use tighter memory-full test, one that checks
9954 for alloca overflow. Don't compute the address of the object just
9955 before an array, as that's not portable. Use EMACS_INT, not
9956 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
9957 * callint.c (Fcall_interactively):
9958 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9959 * callproc.c (call_process_kill, Fcall_process):
9960 Don't assume pid_t fits into an Emacs fixnum.
9961 (call_process_cleanup, Fcall_process, child_setup):

9969 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
9970 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9971 (casify_object): Avoid integer overflow when overallocating buffer.
9972 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
9973 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
9974 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
9975 * category.h (CATEGORYP): Don't assume arg is nonnegative.
9976 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
9977 integers are now checked earlier. All uses replaced with XINT.
9979 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9980 For CCL_MapSingle, check that content and value are in int range.

9982 Check that Vcode_version_map_vector is a vector.
9983 (resolve_symbol_ccl_program): Check that vector header is in range.
9984 Always copy the vector, so that we can check its contents reliably
9985 now rather than having to recheck each instruction as it's being
9986 executed. Check that vector words fit in 'int'.
9987 (ccl_get_compiled_code, Fregister_ccl_program)
9988 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
9989 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
9990 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
9991 contents are in range.
9992 (Fccl_execute_on_string): Check that status is in range.
9993 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
9994 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
9995 Accept and return EMACS_INT, not int, because callers can pass values
9997 (c_string_width, strwidth, lisp_string_width, chars_in_text)
9998 (multibyte_chars_in_text, parse_str_as_multibyte)
9999 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)

10002 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10003 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
10004 avoid mishandling large integers.

10016 Don't assume unsigned int fits into fixnum, or that fixnum fits

10671 (Fx_create_frame, x_create_tip_frame, Fx_show_tip)
10672 (Fx_hide_tip, Fx_file_dialog, Fx_select_font):
10673 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10674 (Fx_change_window_property): Don't assume fixnums fit in int.
10675 * xfont.c (xfont_chars_supported):
10676 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10677 * xmenu.c (Fx_popup_dialog, set_frame_menubar)
10678 (create_and_show_popup_menu, create_and_show_dialog, xmenu_show):
10679 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10680 * xml.c (parse_region):
10681 * xrdb.c (magic_file_p):
10682 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10683 * xselect.c (TRACE1): Don't assume pid_t promotes to int.
10684 (x_get_local_selection, x_reply_selection_request)
10685 (x_handle_selection_request, wait_for_property_change):
10686 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10687 (selection_data_to_lisp_data): Use short, not EMACS_INT, where
10688 short is wide enough.
10689 (x_send_client_event): Don't assume fixnum fits in int.
10690 * xterm.c (x_x_to_emacs_modifiers):
10691 Don't assume EMACS_INT overflows nicely into int.
10692 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
10693 may come from Lisp.
10694 (handle_one_xevent): NATNUMP can eval its arg twice.
10695 (x_connection_closed):
10696 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10697 * xterm.h: Adjust decls to match defn changes elsewhere.
10698 (struct scroll_bar): Use struct vectorlike_header
10699 rather than rolling our own approximation.
10700 (SCROLL_BAR_VEC_SIZE): Remove; not used.
10702 2012-05-25 Glenn Morris <rgm@gnu.org>
10704 * lisp.mk (lisp): Update for more files being compiled now.
10706 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
10708 * lread.c: Remove `read_pure' which makes no difference.
10709 (read_pure): Remove var.
10710 (unreadpure): Remove function.
10711 (readevalloop): Don't call read_list with -1 flag.
10712 (read1, read_vector): Don't test read_pure any more.
10713 (read_list): Simplify.
10715 * fileio.c, character.h: Minor style tweaks.
10717 2012-05-24 Dmitry Antipov <dmantipov@yandex.ru>
10719 * window.h (clip_changed): Remove useless declaration.
10721 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
10723 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
10724 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
10726 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
10729 This directory predates autoconf and is no longer needed nowadays.
10730 Move its few remaining bits of functionality to where they're needed.
10731 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
10732 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
10733 * m/template.h: Remove.
10734 * Makefile.in (M_FILE): Remove. All uses removed.
10735 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
10736 * lisp.h (USE_LSB_TAG):
10737 * mem-limits.h (EXCEEDS_LISP_PTR):
10738 Use VAL_MAX, not VALBITS, in #if.
10739 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
10740 (EMACS_UINT): Define unconditionally now.
10741 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
10742 (BITS_PER_EMACS_INT): New constants, replacing
10743 what used to be in config.h, but not useful in #if.
10744 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
10745 define them any more.
10746 (VAL_MAX): New macro.
10748 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
10749 BITS_PER_EMACS_INT, in #if.
10750 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
10751 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
10752 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
10753 * s/ms-w32.h (DATA_START):
10754 Move here from removed file m/intel386.h.
10755 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
10756 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
10758 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
10760 Assume C89 or later.
10761 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
10762 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
10764 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
10765 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
10766 * textprop.c, tparam.c (NULL): Remove.
10767 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
10768 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
10769 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
10770 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
10771 * xterm.c (input_signal_count): Assume volatile works.
10773 2012-05-21 Ken Brown <kbrown@cornell.edu>
10775 * xgselect.c (xg_select): Fix first argument in call to 'select'
10778 2012-05-20 Ken Brown <kbrown@cornell.edu>
10780 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
10781 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
10783 2012-05-19 Ken Brown <kbrown@cornell.edu>
10785 * xfns.c (x_in_use): Remove `static' qualifier.
10786 * xterm.h (x_in_use): Declare.
10787 * xgselect.c: Include xterm.h.
10788 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
10789 and `display_arg' (bug#9754).
10791 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
10793 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
10795 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
10796 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
10798 2012-05-18 Eli Zaretskii <eliz@gnu.org>
10800 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
10802 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
10803 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
10805 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
10806 reference to image_cache->refcount.
10807 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
10809 2012-05-17 Juri Linkov <juri@jurta.org>
10811 * search.c (Fword_search_regexp, Fword_search_backward)
10812 (Fword_search_forward, Fword_search_backward_lax)
10813 (Fword_search_forward_lax): Move functions to isearch.el
10814 (bug#10145, bug#11381).
10816 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
10818 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
10820 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
10822 * lread.c (init_obarray): Declare Qt and Qnil as special.
10824 2012-05-14 Glenn Morris <rgm@gnu.org>
10826 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
10827 Put "libexec" before "bin", for the sake of init_callproc_1.
10829 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
10831 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
10833 * unexaix.c: Port to more-recent AIX compilers.
10834 (report_error, report_error_1, make_hdr, copy_sym)
10835 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
10836 Make arguments const char *, not char *, to avoid violations of C
10837 standard and to fix some AIX warnings reported by Gilles Pion.
10839 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10841 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
10842 already have overlays loaded.
10843 (handle_single_display_spec): Before returning without displaying
10844 fringe bitmap, synchronize the bidi iterator with the main display
10845 iterator, by calling iterate_out_of_display_property.
10846 (iterate_out_of_display_property): Detect buffer iteration by
10847 testing that it->string is a Lisp string.
10848 (get_next_display_element): When the current object is exhausted,
10849 and there's something on it->stack, call set_iterator_to_next to
10850 proceed with what's on the stack, instead of returning zero.
10851 (set_iterator_to_next): If called at the end of a Lisp string,
10852 proceed to consider_string_end without incrementing string
10853 position. Don't increment display vector index past the end of
10854 the display vector. (Bug#11417)
10855 (pos_visible_p): Don't report a position visible when move_it_to
10856 stopped at the last line of window, which happens to be scanned
10857 backwards by the bidi iteration. (Bug#11464)
10859 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10861 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
10862 and right-margin display specs even if the spec is invalid or we
10863 are on a TTY, and thus unable to display on the fringes.
10864 That's because the text with the property will not be displayed anyway,
10865 so we need to signal to the caller that this is a "replacing"
10866 display spec. This fixes display when the spec is invalid or we
10869 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
10871 * unexaix.c (make_hdr): Fix typo in prototype.
10872 This bug broke the build on AIX. Problem reported by Gilles Pion.
10874 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
10876 * keyboard.c (kbd_buffer_get_event): Read special events also in
10877 batch mode. (Bug#11415)
10879 2012-05-12 Glenn Morris <rgm@gnu.org>
10881 * ns.mk: Update for ns_appbindir no longer having trailing "/".
10883 2012-05-12 Eli Zaretskii <eliz@gnu.org>
10885 * lisp.mk (lisp): Add newcomment.elc.
10887 2012-05-12 Glenn Morris <rgm@gnu.org>
10889 * Makefile.in (MKDIR_P): New, set by configure.
10890 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
10892 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
10894 Remove unused function hourglass_started.
10895 * dispextern.h (hourglass_started):
10896 * w32fns.c (hourglass_started):
10897 * xdisp.c (hourglass_started): Remove.
10899 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
10901 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
10902 Update dependencies.
10904 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
10906 * xgselect.c (xg_select): Put maxfds+1 into a var.
10907 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
10909 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
10911 2012-05-10 Dave Abrahams <dave@boostpro.com>
10913 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
10914 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
10916 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
10918 * dbusbind.c (xd_registered_buses): New internal Lisp object.
10919 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
10920 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
10921 Initialize xd_registered_buses.
10923 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
10925 Untag more efficiently if USE_LSB_TAG.
10926 This is based on a proposal by YAMAMOTO Mitsuharu in
10927 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
10928 For an admittedly artificial (nth 8000 longlist) benchmark on
10929 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
10930 Emacs's overall text size by 1%.
10931 * lisp.h (XUNTAG): New macro.
10932 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
10933 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
10934 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
10935 * eval.c (Fautoload):
10936 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
10937 * frame.h (XFRAME): Use XUNTAG.
10939 Port recent dbusbind.c changes to 32-bit --with-wide-int.
10940 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
10941 Remove unportable assumptions about print widths of types like
10943 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
10944 intptr_t when converting between pointer and integer, to avoid GCC
10945 warnings about wrong width.
10947 2012-05-09 Eli Zaretskii <eliz@gnu.org>
10949 * w32proc.c (new_child): Force Windows to reserve only 64KB of
10950 stack for each reader_thread, instead of defaulting to 8MB
10951 determined by the linker. This avoids failures in creating
10952 subprocesses on Windows 7, see the discussion in this thread:
10953 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
10955 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
10957 Fix up display of the *Minibuf-0* buffer in the mini window.
10958 * keyboard.c (read_char): Don't clear the echo area if there's no
10960 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
10961 contents of *Minibuf-0*) if there's no message displayed in its stead.
10963 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
10965 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
10968 2012-05-06 Chong Yidong <cyd@gnu.org>
10970 * lisp.mk (lisp): Update.
10972 2012-05-05 Jim Meyering <meyering@redhat.com>
10974 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
10976 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
10978 * data.c (PUT_ERROR): New macro.
10979 (syms_of_data): Use it. Add new error type `user-error'.
10980 * undo.c (user_error): New function.
10981 (Fprimitive_undo): Use it.
10982 * print.c (print_error_message): Adjust print style for `user-error'.
10983 * keyboard.c (user_error): New function.
10984 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
10986 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
10988 Do not limit current-time-string to years 1000..9999.
10989 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
10990 (Fcurrent_time_string): Support any year that is supported by the
10991 underlying localtime representation. Don't use asctime, as it
10992 has undefined behavior for years outside the range -999..9999.
10994 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
10996 Fix race conditions involving setenv, gmtime, localtime, asctime.
10997 Without this fix, interrupts could mess up code that uses these
10998 nonreentrant functions, since setting TZ invalidates existing
10999 tm_zone or tzname values, and since most of these functions return
11000 pointers to static storage.
11001 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
11002 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
11003 Grow the critical sections to include not just invoking
11004 localtime/gmtime, but also accessing these functions' results
11005 including their tm_zone values if any, and any related TZ setting.
11006 (format_time_string): Last arg is now struct tm *, not struct tm **,
11007 so that the struct tm is saved in the critical section.
11008 All callers changed. Simplify allocation of initial buffer, partly
11009 motivated by the fact that memory allocation needs to be outside
11010 the critical section.
11012 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
11014 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
11015 with RESET_INTERVAL.
11017 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
11018 Remove duplicated buffer name initialization.
11020 2012-05-02 Jim Meyering <jim@meyering.net>
11022 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
11024 * xfns.c (x_window): Use xstrdup (Bug#11375).
11026 2012-05-02 Eli Zaretskii <eliz@gnu.org>
11028 * xdisp.c (pos_visible_p): If already at a newline from the
11029 display string before the 'while' loop, don't walk back the glyphs
11030 from it3.glyph_row. Solves assertion violation when the display
11031 string begins with a newline (egg.el). (Bug#11367)
11033 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
11035 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
11038 2012-05-01 Glenn Morris <rgm@gnu.org>
11040 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
11041 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
11042 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
11043 All were removed before 23.1.
11045 * dispnew.c: Remove HAVE_LIBNCURSES test;
11046 it is always true on relevant platforms.
11048 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
11049 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
11051 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
11053 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
11055 * .gdbinit (xpr): Remove checks for no longer existing misc types.
11056 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
11059 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
11061 Do not avoid creating empty evaporating overlays (Bug#9642).
11062 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
11063 That is, do not delete an evaporating overlay if it becomes
11064 empty after its bounds are adjusted to fit within its buffer.
11065 This fix caused other problems, and I'm reverting it until we get
11066 to the bottom of them.
11068 2012-04-27 Chong Yidong <cyd@gnu.org>
11070 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
11072 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11074 * xdisp.c (pos_visible_p): If the window start position is beyond
11075 ZV, start the display from buffer beginning. Prevents assertion
11076 violation in init_iterator when the minibuffer window is scrolled
11077 via the scroll bar.
11079 * window.c (window_scroll_pixel_based): Likewise.
11081 2012-04-27 Chong Yidong <cyd@gnu.org>
11083 * keymap.c (where_is_internal): Doc fix (Bug#10872).
11085 2012-04-27 Glenn Morris <rgm@gnu.org>
11087 * fileio.c (Fcopy_file, Fset_file_selinux_context):
11088 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
11090 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11092 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
11093 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
11095 2012-04-26 Eli Zaretskii <eliz@gnu.org>
11097 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
11098 display element, check also the underlying string or buffer
11099 character. (Bug#11341)

11104 running on Windows 9X/Me.
11106 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
11108 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.

11129 Do not create empty overlays with the evaporate property (Bug#9642).
11130 * buffer.c (Fmove_overlay): Delete an evaporating overlay
11131 if it becomes empty after its bounds are adjusted to fit within
11132 its buffer. Without this fix, in a nonempty buffer (let ((o
11133 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
11134 yields an empty overlay that has the evaporate property, which is
11135 not supposed to happen.

11158 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
11159 (__malloc_size_t, __malloc_ptrdiff_t):
11160 Remove. All uses removed, replaced by the definiens if needed,
11161 since we can assume C89 or better now.

11250 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
11252 * sysdep.c [__FreeBSD__]: Minor cleanups.
11253 (list_system_processes, system_process_attributes) [__FreeBSD__]:
11254 Use Emacs indenting style more consistently. Avoid some casts.
11255 Use 'double' consistently rather than mixing 'float' and 'double'.

11266 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
11268 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
11269 It is never used otherwise.
11271 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
11273 * print.c (print_preprocess): Only check print_depth if print-circle

11280 * process.c (wait_reading_process_output): If EIO occurs on a pty,
11281 set the status to "failed" and ensure that sentinel is run.
11283 2012-04-20 Glenn Morris <rgm@gnu.org>
11285 * process.c (Fset_process_inherit_coding_system_flag)
11286 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

11314 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
11315 -Wunused-result, -Wunused-variable. This should go away once
11316 the Emacs and Gnulib regex code is merged.

11336 New extern decls, to avoid calling undeclared functions.
11337 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
11338 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
11339 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
11340 (NEED_MEM_INSERT): New macro.
11341 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
11342 Remove one incorrect comment and fix another.

11409 2012-04-11 Daniel Colascione <dancol@dancol.org>
11411 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
11412 against is gone. It's better to use vfork now so that when Cygwin
11413 gains a new, working vfork, we use it automatically (bug#10398).
11415 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

11465 (Fdefvar): Caller changed.
11467 * callint.c (Finteractive, Fcall_interactively):
11468 * minibuf.c (Fread_variable): Callers changed.
11470 2012-04-09 Eli Zaretskii <eliz@gnu.org>
11472 * xdisp.c (set_cursor_from_row): If the display string appears in
11473 the buffer at position that is closer to point than the position
11474 after the display string, display the cursor on the first glyph of
11475 the display string. Fixes cursor display when a 'display' text
11476 property immediately follows invisible text. (Bug#11094)
11478 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
11480 composite.c: use 'double' consistently
11481 * composite.c (get_composition_id): Use 'double' consistently
11482 instead of converting 'float' to 'double' and vice versa; this is
11483 easier to understand and avoids a GCC warning.
11485 2012-04-09 Glenn Morris <rgm@gnu.org>
11487 * Makefile.in: Generate leim-list with bootstrap-emacs, in
11488 preparation for dumping it with emacs. (Bug#4789)

11532 [!WINDOWSNT]: New macros.
11533 (init_libxml2_functions, libxml2_loaded_p): New functions.
11534 (parse_region): Call fn_xmlCheckVersion instead of using the macro
11535 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
11536 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
11537 Calls xmlCleanupParser only if libxml2 was loaded (or statically
11539 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
11540 Call init_libxml2_functions before calling libxml2 functions.
11541 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
11543 * emacs.c: Don't include libxml/parser.h.
11544 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
11545 xmlCleanupParser directly.
11547 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
11549 2012-04-07 Eli Zaretskii <eliz@gnu.org>
11551 * indent.c (Fvertical_motion): If there is a display string at
11552 point, use it.vpos to compute how many lines to backtrack after
11553 move_it_to point. (Bug#11133)
11555 2012-04-06 Eli Zaretskii <eliz@gnu.org>
11557 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
11558 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
11559 about subtle differences between FETCH_CHAR* and STRING_CHAR*
11560 macros related to unification of CJK characters. For the details,
11561 see the discussion following the message here:
11562 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
11564 2012-04-04 Chong Yidong <cyd@gnu.org>
11566 * keyboard.c (Vdelayed_warnings_list): Doc fix.
11568 2012-04-01 Eli Zaretskii <eliz@gnu.org>
11570 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
11571 instead of alloca. (Bug#11138)
11573 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
11575 * w32menu.c (is_simple_dialog): Properly check lisp types.
11578 2012-03-31 Eli Zaretskii <eliz@gnu.org>
11580 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
11581 position we get to after a call to move_it_to fails the
11582 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
11583 only if we wind up in a string from display property. (Bug#11063)
11585 * window.c (Fdelete_other_windows_internal): Invalidate the row
11586 and column information about mouse highlight, so that redisplay
11587 restores it after reallocating the glyph matrices. (Bug#7464)
11589 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
11590 string comes from a `display' text property, use the buffer
11591 position of that property as if we actually saw that position in
11593 (move_it_by_lines): Remove the assertion that
11594 "it->current_x == 0 && it->hpos == 0" which can be legitimately
11595 violated when there's a before-string at the beginning of a line.
11598 2012-03-30 Eli Zaretskii <eliz@gnu.org>
11600 * xdisp.c (append_space_for_newline): If the default face was
11601 remapped, use the remapped face for the appended newline.
11602 (extend_face_to_end_of_line): Use the remapped default face for
11603 extending the face to the end of the line.
11604 (display_line): Call extend_face_to_end_of_line when the default
11605 face was remapped. (Bug#11068)
11607 2012-03-29 Eli Zaretskii <eliz@gnu.org>
11609 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
11611 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
11613 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
11615 2012-03-27 Glenn Morris <rgm@gnu.org>
11617 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
11620 2012-03-26 Kenichi Handa <handa@m17n.org>
11622 * dispextern.h (struct glyph): Fix previous change. Change the
11623 bit length of glyphless.ch to 25 (Bug#11082).
11625 2012-03-26 Chong Yidong <cyd@gnu.org>
11627 * keyboard.c (Vselection_inhibit_update_commands): New variable.
11628 (command_loop_1): Use it; inhibit selection update for
11629 handle-select-window too (Bug#8996).
11631 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
11633 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
11635 2012-03-25 Kenichi Handa <handa@m17n.org>
11637 * dispextern.h (struct glyph): Change the bit length of
11638 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
11640 2012-03-24 Eli Zaretskii <eliz@gnu.org>
11642 * s/ms-w32.h (tzname): Include time.h before redirecting to
11643 _tzname. Fixes the MSVC build. (Bug#9960)
11645 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
11647 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
11650 * xterm.c (XTread_socket): Only modify handling_signal if
11651 !SYNC_INPUT. (Bug#11080)
11653 2012-03-23 Eli Zaretskii <eliz@gnu.org>
11655 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
11656 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
11657 when fetching a multibyte character consumes more bytes than
11658 CHAR_BYTES returns, due to unification of CJK characters in
11659 string_char. (Bug#11073)
11661 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
11663 * process.c (wait_reading_process_output): Handle pty disconnect
11664 by refraining from sending oneself a SIGCHLD (bug#10933).
11666 2012-03-22 Chong Yidong <cyd@gnu.org>
11668 * dispextern.h (struct it): New member string_from_prefix_prop_p.
11670 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
11671 Mark string as coming from a prefix property.
11672 (handle_face_prop): Use default face for prefix strings (Bug#4281).
11673 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
11675 2012-03-21 Chong Yidong <cyd@gnu.org>
11677 * xfaces.c (Vface_remapping_alist): Doc fix.
11679 2012-03-20 Eli Zaretskii <eliz@gnu.org>
11681 * w32proc.c (Fw32_set_console_codepage)
11682 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
11685 2012-03-20 Chong Yidong <cyd@gnu.org>
11687 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
11688 to reflect default non-nil value of redisplay-dont-pause.
11690 2012-03-19 Kenichi Handa <handa@m17n.org>
11692 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
11693 it fit in a valid range (Bug#11003).
11695 2012-03-18 Eli Zaretskii <eliz@gnu.org>
11697 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
11698 that is not from display property, accept the row as a "cursor
11699 row" if one of the string's character has a non-nil `cursor'
11700 property. Fixes cursor positioning when there are newlines in
11701 overlay strings, e.g. in icomplete.el. (Bug#11035)
11703 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
11705 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
11707 2012-03-12 Chong Yidong <cyd@gnu.org>
11709 * eval.c (inhibit_lisp_code): Rename from
11710 inhibit_window_configuration_change_hook; move from window.c.
11712 * xfns.c (unwind_create_frame_1, Fx_create_frame):
11713 * window.c (run_window_configuration_change_hook)
11714 (syms_of_window): Callers changed.

11720 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
11722 2012-03-10 Chong Yidong <cyd@gnu.org>
11724 * frame.c (other_visible_frames): Don't assume the selected frame
11725 is visible (Bug#10955).
11727 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
11729 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
11731 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
11733 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
11734 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
11737 2012-03-03 Glenn Morris <rgm@gnu.org>
11739 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
11741 2012-03-02 Eli Zaretskii <eliz@gnu.org>
11743 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
11744 position past the first glyph_row that ends at ZV. (Bug#10902)
11745 (redisplay_window, next_element_from_string): Fix typos in
11747 (redisplay_window): Pass to move_it_vertically the margin in
11748 pixels, not in screen lines.
11750 2012-03-02 Glenn Morris <rgm@gnu.org>
11752 * buffer.c (buffer-list-update-hook): Doc fix.
11754 2012-02-29 Eli Zaretskii <eliz@gnu.org>
11756 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
11757 push_it before setting up the iterator for the first overlay
11758 string, even if we have an empty string loaded.
11759 (next_overlay_string): If there's an empty string on the iterator
11760 stack, pop the stack. (Bug#10903)
11762 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
11764 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
11765 Suggested by Stefan Monnier in
11766 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
11767 * alloc.c (widen_to_Lisp_Object): New static function.
11768 (mark_memory): Also mark Lisp_Objects by fetching pointer words
11769 and widening them to Lisp_Objects. This would work even if
11770 USE_LSB_TAG is defined and wide integers are used, which might
11771 happen in a future version of Emacs.
11773 2012-02-25 Chong Yidong <cyd@gnu.org>
11775 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
11778 * xselect.c (Fx_selection_exists_p): Doc fix.
11779 (x_clipboard_manager_save_all): Print an informative message
11780 before saving to clipboard manager.
11782 2012-02-24 Chong Yidong <cyd@gnu.org>
11784 * keyboard.c (process_special_events): Handle all X selection
11785 requests in kbd_buffer, not just the next one (Bug#8869).
11787 2012-02-23 Chong Yidong <cyd@gnu.org>
11789 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
11790 call when setting menu-bar-lines and tool-bar-lines parameters.
11791 (unwind_create_frame_1): New helper function.
11793 * window.c (inhibit_window_configuration_change_hook): New var.
11794 (run_window_configuration_change_hook): Obey it.
11795 (syms_of_window): Initialize it.
11797 2012-02-22 Chong Yidong <cyd@gnu.org>
11799 * xterm.c (x_draw_image_relief): Add missing type check for
11800 Vtool_bar_button_margin (Bug#10743).
11802 2012-02-21 Chong Yidong <cyd@gnu.org>
11804 * fileio.c (Vfile_name_handler_alist): Doc fix.
11806 * buffer.c (Fget_file_buffer): Protect against invalid file
11807 handler return value.
11809 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
11811 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
11812 when computing $valmask.
11814 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
11815 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
11816 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
11817 It's useless in that case, and it can cause problems on hosts
11818 that allocate halves of EMACS_INT values separately.
11819 Reported by Dan Horák. Diagnosed by Andreas Schwab in
11820 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
11821 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
11822 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
11823 it avoids undefined behavior on hosts where shifting right by more
11824 than the word width has undefined behavior.
11826 2012-02-19 Chong Yidong <cyd@gnu.org>
11828 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
11829 (Funhandled_file_name_directory, Ffile_name_as_directory)
11830 (Fdirectory_file_name, Fexpand_file_name)
11831 (Fsubstitute_in_file_name): Protect against invalid file handler
11832 return values (Bug#10845).
11834 2012-02-18 Eli Zaretskii <eliz@gnu.org>
11836 * .gdbinit (pitx): Fix incorrect references to fields of the
11839 2012-02-17 Chong Yidong <cyd@gnu.org>

11843 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
11845 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
11846 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
11848 2012-02-15 Chong Yidong <cyd@gnu.org>
11850 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
11851 marked as special. Also, starting docstrings with * is obsolete.
11853 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
11855 * gnutls.c (emacs_gnutls_write): Fix last change.

11859 * gnutls.c (emacs_gnutls_write): Set errno appropriately for
11862 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
11864 * keymap.c (Fsingle_key_description): Handle char ranges.
11866 2012-02-12 Chong Yidong <cyd@gnu.org>
11868 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
11869 as that creates a dangerous corner case.
11871 * window.c (Fdelete_window_internal): Invalidate the mouse
11872 highlight (Bug#9904).
11874 2012-02-12 Glenn Morris <rgm@gnu.org>
11876 * xselect.c (Fx_own_selection_internal)
11877 (Fx_get_selection_internal, Fx_disown_selection_internal)
11878 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
11879 * nsselect.m (Fx_own_selection_internal)
11880 (Fx_disown_selection_internal, Fx_selection_exists_p)
11881 (Fx_selection_owner_p, Fx_get_selection_internal):
11882 Sync docs and argument specs with the xselect.c versions.
11884 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
11886 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
11888 2012-02-11 Eli Zaretskii <eliz@gnu.org>
11890 * w32select.c (Fx_selection_exists_p): Sync doc string and
11891 argument list with xselect.c. (Bug#10783)
11893 * w16select.c (Fx_selection_exists_p): Sync doc string and
11894 argument list with xselect.c. (Bug#10783)
11896 2012-02-10 Glenn Morris <rgm@gnu.org>
11898 * fns.c (Fsecure_hash): Doc fix.
11900 2012-02-09 Kenichi Handa <handa@m17n.org>
11902 * coding.c (produce_chars): Fix updating of src_end (Bug#10701).
11904 2012-02-07 Chong Yidong <cyd@gnu.org>
11906 * buffer.c (Fbuffer_local_variables)
11907 (buffer_lisp_local_variables): Handle unbound vars correctly;
11908 don't let Qunbound leak into Lisp.
11910 2012-02-07 Glenn Morris <rgm@gnu.org>
11912 * image.c (Fimagemagick_types): Doc fix.
11914 * image.c (imagemagick-render-type): Change it from a lisp object
11915 to an integer. Move the doc here from the lisp manual.
11916 Treat all values not equal to 0 the same.
11918 2012-02-06 Chong Yidong <cyd@gnu.org>
11920 * doc.c (store_function_docstring): Avoid applying docstring of
11921 alias to base function (Bug#2603).
11923 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>

11928 2012-02-04 Chong Yidong <cyd@gnu.org>
11930 * nsterm.m: Declare a global (Bug#10694).
11932 2012-02-04 Eli Zaretskii <eliz@gnu.org>
11934 * w32.c (get_emacs_configuration_options):
11935 Include --enable-checking, if specified, in the return value.
11937 2012-02-04 Martin Rudalics <rudalics@gmx.at>
11939 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
11940 after rounding frame sizes. (Bug#9723)
11942 2012-02-04 Eli Zaretskii <eliz@gnu.org>
11944 * keyboard.c (adjust_point_for_property): Don't position point
11945 before BEGV. (Bug#10696)
11947 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
11949 Handle overflow when computing char display width (Bug#9496).
11950 * character.c (char_width): Return EMACS_INT, not int.
11951 (char_width, c_string_width): Check for overflow when
11952 computing the width; this is possible now that individual
11953 characters can have unbounded width. Problem introduced
11954 by merge from Emacs 23 on 2012-01-19.
11956 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
11958 * dbusbind.c (Fdbus_register_method): Mention the return value
11959 :ignore in the docstring.
11961 2012-02-02 Glenn Morris <rgm@gnu.org>
11963 * callproc.c (Fcall_process, Fcall_process_region): Doc fix.
11965 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:
11966 Unconditionally set to t. (Bug#10673)

11971 2012-02-02 Kenichi Handa <handa@m17n.org>
11973 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
11974 0, do not call append_composite_glyph.
11976 2012-02-02 Kenichi Handa <handa@m17n.org>
11978 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
11980 (x_produce_glyphs): If the component of a composition is a null
11981 string, set it->pixel_width to 1 to avoid zero-width glyph.
11983 2012-02-01 Eli Zaretskii <eliz@gnu.org>
11985 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
11986 first 2 arguments are identical. This makes inserting large
11987 output from a subprocess an order of magnitude faster on
11988 MS-Windows, where all sbrk'ed memory is always contiguous.
11990 2012-01-31 Glenn Morris <rgm@gnu.org>
11992 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

12518 * xdisp.c (redisplay_window): If cursor row is not fully visible
12519 after recentering, and scroll-conservatively is set to a large
12520 number, scroll window by a few more lines to make the cursor fully
12521 visible and out of scroll-margin. (Bug#10105)
12522 (start_display): Don't move to the next line if the display should
12523 start at a newline that is part of a display vector or an overlay
12524 string. (Bug#10119)

12603 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
12604 Otherwise, valgrind does not work on some platforms.
12605 Problem reported by Andreas Schwab in
12606 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
12607 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
12608 is set, removing the need for VIRT_ADDRESS_VARIES.
12609 (PURE_P): Use a more-efficient implementation that needs just one
12610 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
12611 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
12612 to 4 (xorl, subq, cmpq, setbe).
12613 * alloc.c (pure): Always extern now, since that's the
12614 VIRT_ADDR_VARIES behavior.

12616 consistency with the new puresize.h.
12617 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
12618 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

12624 (erase_phys_cursor, update_window_cursor, show_mouse_face)
12625 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
12626 behave as if the cursor position were at the window margin.
12628 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
12629 and the cursor position is out of bounds, behave as if the cursor
12630 position were at the window margin. (Bug#10075)
12632 2011-11-18 Chong Yidong <cyd@gnu.org>
12634 * window.c (Fwindow_combination_limit): Make first argument

12653 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
12655 * xdisp.c (row_hash): New function, body extracted from
12656 compute_line_metrics.
12657 (compute_line_metrics): Call row_hash, instead of computing the
12660 * dispnew.c (verify_row_hash): Call row_hash for computing the
12661 hash code of a row, instead of duplicating code from xdisp.c.
12663 * dispextern.h (row_hash): Add prototype.
12665 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
12667 * frame.c (delete_frame): Don't delete the terminal when the last

12693 (Fsplit_window_internal, saved_window)
12694 (Fset_window_configuration, save_window_save): Rename all
12695 occurrences of window_nest to window_combination_limit.

12701 2011-11-14 Eli Zaretskii <eliz@gnu.org>
12703 * xdisp.c (display_line): Move the call to
12704 highlight_trailing_whitespace before the call to
12705 compute_line_metrics, since the latter needs to see the final
12706 faces of all the glyphs to compute ROW's hash value.
12707 Fixes assertion violations in row_equal_p. (Bug#10035)
12709 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
12711 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
12712 just return (bug#10044).
12714 2011-11-12 Eli Zaretskii <eliz@gnu.org>
12716 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
12717 with user-defined heap size. Bump the default size of the temacs
12718 heap to 27MB, to avoid memory warning when running temacs.
12719 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
12721 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
12722 current_matrix and desired_matrix. (Bug#9990)
12723 (verify_row_hash) [XASSERTS]: New function.

12768 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
12770 Avoid some portability problems by eschewing 'extern inline' functions.
12771 The trivial performance wins aren't worth the portability hassles; see
12772 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
12774 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

12777 by removing the "extern"s.
12778 * intervals.c (adjust_intervals_for_insertion)
12779 (adjust_intervals_for_deletion): Undo previous change,
12780 making these static again.
12781 (offset_intervals, temp_set_point_both, temp_set_point)
12782 (copy_intervals_to_string): No longer inline.
12783 * xdisp.c (window_text_bottom_y, window_box_width)

12840 * xmenu.c (cleanup_widget_value_tree): New function.
12841 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
12842 calling free_menubar_widget_value_tree directly (Bug#9830).

12848 (window_box_width, window_box_left, window_box_left_offset)
12849 (window_box_right, window_box_right_offset): Declare extern.
12850 Otherwise, these inline functions do not conform to C99 and
12851 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
12852 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
12853 * intervals.c (adjust_intervals_for_insertion)

12856 (static_offset_intervals): Remove.
12857 (offset_intervals): Rewrite using the old contents of
12858 static_offset_intervals. The old version didn't conform to C99
12859 because an extern inline function contained a reference to an
12860 identifier with static linkage.

12912 * nsfns.m: Declare image_cache_refcount if GLYPH_DEBUG.
12913 (unwind_create_frame): New function (Bug#9943).
12914 (Fx_create_frame): Restructure code to be more similar to the one in
12915 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).

12931 Support MSVC build with newer versions of Visual Studio.
12932 * makefile.w32-in (TAGS-gmake): Don't use $(patsubst ...), as

12937 which are not supported by MSVC.
12938 (Lisp_Symbol, Lisp_Misc_Any, Lisp_Marker, Lisp_Misc_Overlay)

12954 [_MSC_VER]: Include sys/timeb.h, sys/stat.h, and signal.h.
12955 (fstat, stat, utime) [_MSC_VER]: Redirect to their sys_* cousins.
12956 (malloc, free, realloc, calloc) [_MSC_VER]: Always redirect to the
12958 (alloca) [_MSC_VER]: Define to _alloca.
12960 * lisp.h (DECL_ALIGN) [_MSC_VER]: Define for MSVC.
12962 * regex.c <re_char> [_MSC_VER]: A separate definition for MSVC.
12964 2011-11-04 Eli Zaretskii <eliz@gnu.org>
12966 * xdisp.c (note_mouse_highlight): If either of
12967 previous/next-single-property-change returns nil, treat that as
12968 the beginning or the end of the buffer. (Bug#9955)
12970 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
12972 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or
12973 label is not null (Bug#9951).
12974 (xg_tool_item_stale_p): Handle the fact that wimage and/or wlbl

12979 * window.c (Fwindow_body_size): Mention in the doc string that the
12980 return value is in frame's canonical units. (Bug#9949)
12982 2011-11-03 Eli Zaretskii <eliz@gnu.org>
12984 * xdisp.c (note_mouse_highlight): Initialize `area'. (Bug#9947)
12986 * w32fns.c (unwind_create_frame): If needed, free the glyph

12990 2011-11-01 Eli Zaretskii <eliz@gnu.org>
12992 * xdisp.c (mouse_face_from_buffer_pos): Fix a typo in a comment.
12993 Don't stop backward scan on the continuation glyph, even though
12994 its CHARPOS is positive.
12995 (mouse_face_from_buffer_pos, note_mouse_highlight):
12996 Rename cover_string to disp_string.
12998 2011-11-01 Martin Rudalics <rudalics@gmx.at>
13000 * window.c (temp_output_buffer_show): Don't use
13001 Vtemp_buffer_show_specifiers.
13002 (Vtemp_buffer_show_specifiers): Remove unused variable.
13004 2011-10-30 Eli Zaretskii <eliz@gnu.org>
13006 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
13007 past the beginning of the current glyph matrix.
13009 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
13011 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.
13012 (x_error_handler): Ignore BadMatch for X_SetInputFocus for
13013 HAVE_GTK3 (Bug#9869).
13015 * gtkutil.c (xg_win_to_widget, xg_event_is_for_menubar): Initialize
13016 type to GDK_NOTHING so valgrind does not complain (Bug#9901).
13018 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
13020 * xterm.c: Declare x_handle_net_wm_state to return int.
13021 (handle_one_xevent): Check if we are iconified but don't have
13022 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
13023 (get_current_wm_state): Return non-zero if not hidden,
13024 check for _NET_WM_STATE_HIDDEN (Bug#9893).

13031 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
13032 so that this new function doesn't get optimized away by a
13033 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
13035 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
13037 * frame.h (MOUSE_HL_INFO): Remove excess parens.
13039 2011-10-29 Eli Zaretskii <eliz@gnu.org>
13041 Fix the `xbytecode' command.
13042 * .gdbinit (xprintbytestr): New command.
13043 (xwhichsymbols): Rename from `which'; all callers changed.
13044 (xbytecode): Print the byte-code string as well.
13046 2011-10-29 Kim Storm <storm@cua.dk>
13048 * alloc.c (which_symbols): New function.
13050 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
13052 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
13055 2011-10-29 Glenn Morris <rgm@gnu.org>
13057 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
13058 Not clear what it was for, and it causes various bugs. (Bug#9839)
13060 2011-10-28 Eli Zaretskii <eliz@gnu.org>
13062 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
13063 possible random value that matches one of those tested as
13064 condition to clear the mouse face.
13066 2011-10-28 Chong Yidong <cyd@gnu.org>
13068 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
13070 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
13072 * window.c (make_window): Initialize phys_cursor_on_p.
13074 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
13076 * lisp.h (struct Lisp_Symbol): Update comments.
13078 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
13080 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
13082 2011-10-28 Eli Zaretskii <eliz@gnu.org>
13084 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
13085 <oslsachem@gmail.com> for helping to debug this.
13087 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
13088 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
13089 (g_b_init_get_glyph_outline_w): New static variables.
13090 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)

13093 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
13095 (w32font_open_internal, compute_metrics):
13096 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
13097 instead of calling the "wide" APIs directly.
13099 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
13101 * w32.h (syms_of_w32font): Add prototype.
13103 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
13105 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
13106 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
13107 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
13108 (Fmove_to_window_line): Doc fix.
13110 2011-10-27 Chong Yidong <cyd@gnu.org>
13112 * process.c (make_process): Set gnutls_state to NULL.
13114 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
13115 non-NULL, regardless of GNUTLS_INITSTAGE.
13116 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
13117 an error. Set process slots as soon as we allocate them.
13119 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
13121 2011-10-27 Chong Yidong <cyd@gnu.org>
13123 * gnutls.c (emacs_gnutls_deinit): New function.

13125 (Fgnutls_deinit, Fgnutls_boot): Use it.
13127 * process.c (make_process): Initialize GnuTLS credentials to NULL.
13128 (deactivate_process): Call emacs_gnutls_deinit.
13130 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
13132 * image.c (x_create_x_image_and_pixmap):
13133 * w32.c (sys_rename, w32_delayed_load):
13134 * w32font.c (fill_in_logfont):
13135 * w32reg.c (x_get_string_resource): Silence compiler warnings.
13137 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
13139 * w32fns.c (w32_default_color_map): New function,
13140 extracted from Fw32_default_color_map.
13141 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
13143 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
13145 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
13147 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
13149 * keyboard.c (test_undefined): New function (bug#9751).
13150 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
13152 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
13154 * sysdep.c (init_sys_modes): Fix the check for the controlling
13155 terminal (Bug#6649).
13157 2011-10-20 Eli Zaretskii <eliz@gnu.org>
13159 * dispextern.h (struct bidi_it): New member next_en_type.
13161 * bidi.c (bidi_line_init): Initialize the next_en_type member.
13162 (bidi_resolve_explicit_1): When next_en_pos is valid for the
13163 current character, check also for next_en_type being WEAK_EN.
13164 (bidi_resolve_weak): Don't enter the expensive loop if the current
13165 position is before next_en_pos. Record the bidi type of the first
13166 non-ET, non-BN character we find, in addition to its position.
13167 (bidi_level_of_next_char): Invalidate next_en_type when
13168 next_en_pos is over-stepped.
13170 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
13172 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
13173 * editfns.c: Rewrite current-time-zone so that it invokes
13174 the equivalent of (format-time-string "%Z") to get the time zone name.
13175 This fixes a bug when the time zone name contains characters that
13176 need converting from the system time locale to Emacs internal format.
13177 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
13178 that patch fixed format-time-string to do the conversion, but
13179 I forgot to fix current-time-zone.
13180 (format_time_string): New function, containing most of
13181 what Fformat_time_string used to contain.
13182 (Fformat_time_string): Rewrite in terms of format_time_string.
13183 This doesn't change this function's behavior.
13184 (current-time-zone): Rewrite to use format_time_string.
13185 This fixes the bug reported by Michael Schierl in
13186 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
13187 Jason Rumney's 2007-06-07 change worked around this bug, but
13189 * systime.h (tzname, timezone): Remove no-longer-used declarations.
13191 2011-10-19 Eli Zaretskii <eliz@gnu.org>
13193 * xdisp.c (start_display): If the character at POS is displayed
13194 via a display vector, reset IT->current.dpvec_index to zero.
13195 (try_window_reusing_current_matrix): If a line ends in a display
13196 vector or the next line starts in a display vector, continue
13197 redrawing the window even though the character position of
13198 start_row was reached.
13201 2011-10-18 Chong Yidong <cyd@gnu.org>
13203 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
13204 with nobreak-char-display too.
13206 2011-10-18 Eli Zaretskii <eliz@gnu.org>
13208 Fix part 3 of bug#9771.
13209 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
13210 (bidi_resolve_neutral): Don't enter the expensive loop looking for
13211 non-neutral characters if the current character is a paragraph
13212 separator (a.k.a. Newline). This avoids running the same
13213 expensive loop twice, once when we consume the preceding newline
13214 and the other time when the line actually needs to be displayed.
13215 Avoid the loop when we see neutrals on the base embedding level
13216 following a character whose directionality is the same as the
13217 paragraph's. This avoids running the expensive loop when a line
13218 ends in a long sequence of neutrals, like control characters.
13219 Add assertion against STRONG_AL type. Slightly rearrange code
13220 that determines the type of a neutral given the first non-neutral
13222 (bidi_level_of_next_char): Set next_en_pos to zero when
13223 invalidating its info.
13225 2011-10-17 Eli Zaretskii <eliz@gnu.org>
13227 * xdisp.c (push_display_prop): Determine whether to record string
13228 or buffer position by IT->string, not by IT->method. Allow
13229 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
13230 (move_it_vertically_backward): Don't look for character position
13231 immediately after the newline when in a continuation line.
13234 2011-10-15 Martin Rudalics <rudalics@gmx.at>
13236 * window.c (coordinates_in_window): Rewrite and delabelize
13237 vertical border check. (Bug#5357) (Bug#9618)
13239 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
13241 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
13242 errors in XSetWindowBorder (bug#9310).
13244 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
13246 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
13247 avoid crash when xmalloc overrun checking is enabled.
13249 2011-10-13 Eli Zaretskii <eliz@gnu.org>
13251 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
13252 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
13253 cursor motion with <left> and <right> arrow keys.
13255 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
13256 some callers set that themselves.
13258 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13260 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
13261 display string and the previous row comes from the same string and
13262 is empty. (Bug#9739) (Bug#9738)
13264 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
13266 * doc.c (get_doc_string): Encode file name (bug#9735).
13268 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13270 * bidi.c (bidi_level_of_next_char):
13271 * xdisp.c (get_visually_first_element): Remove old incorrect
13272 comments regarding the Unicode Line Separator character.
13274 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
13276 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
13278 * alloc.c (Fgc_status): Do not access beyond zombies array
13279 boundary if nzombies > MAX_ZOMBIES.
13280 * alloc.c (dump_zombies): Add missing format specifier.
13282 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
13284 * xdisp.c (set_cursor_from_row): Simplify conditionals,
13285 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
13287 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
13288 Some packages use them to denote characters with modifiers.
13290 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
13292 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
13293 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
13294 matching a pp-number. Rename parameter var to var1.
13296 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
13298 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
13300 2011-10-08 Glenn Morris <rgm@gnu.org>
13302 * callint.c (Fcall_interactively): Give a more explicit error for the
13303 'c' case with a non-character input. (Bug#8479)
13305 2011-10-08 Eli Zaretskii <eliz@gnu.org>
13307 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
13309 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
13310 lines that are hscrolled on the left.
13312 * dispnew.c (buffer_posn_from_coords): Account for a possible
13313 presence of header-line. (Bug#4426)
13315 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
13317 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
13318 Don't advertise functionality which we discourage or doesn't work.
13320 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
13322 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
13323 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
13324 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
13325 this makes Emacs dump core during garbage collection on rare
13326 occasions. sizeof is obviously inferior to offsetof here, so
13327 stick with offsetof.
13328 (GC_POINTER_ALIGNMENT): New macro.
13329 (mark_memory): Omit 3rd (offset) arg; caller changed.
13330 Don't assume EMACS_INT alignment is the same as pointer alignment.
13332 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
13334 * keyboard.c (read_key_sequence_remapped): New var.
13335 (read_key_sequence): Compute remapping in the right buffer.
13336 (command_loop_1): Use read_key_sequence's remapping directly.
13338 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
13340 * dired.c (file_name_completion): Don't expand file name.
13341 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
13342 before checking file name handler.
13344 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
13345 they've been requested explicitly (bug#9591).
13347 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
13349 * keymap.c (Fsingle_key_description): Use make_specified_string
13350 instead of build_string to build string from push_key_description.
13353 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13355 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
13356 This fixes a Y2038 bug on 64-bit hosts.
13357 * buffer.c (reset_buffer):
13358 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
13359 (Fclear_buffer_auto_save_failure):
13360 Use 0, not -1, to represent an unset failure time, since time_t
13361 might not be signed.
13363 Remove dependency on glibc malloc internals.
13364 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13365 Move back here from lisp.h, but with their new implementations.
13366 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13367 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
13368 * charset.c (charset_table_init): New static var.
13369 (syms_of_charset): Use it instead of xmalloc. This removes a
13370 dependency on glibc malloc internals. See Eli Zaretskii's comment in
13371 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
13372 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13373 Move back to alloc.c.
13374 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13375 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
13377 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
13379 * nsterm.m (windowDidResize): Call x_set_window_size only when
13380 ns_in_resize is true. Otherwise set pixelwidth/height and
13381 call change_frame_size (Bug#9628).
13383 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13385 Port --enable-checking=all to Fedora 14 x86-64.
13386 * charset.c (syms_of_charset): Also account for glibc malloc's
13387 internal overhead when calculating the initial malloc maximum.
13389 Port --enable-checking=all to Fedora 14 x86.
13390 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13392 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
13393 (overrun_check_realloc, overrun_check_free):
13394 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
13395 That way, xmalloc returns a properly-aligned pointer even if
13396 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
13397 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
13398 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
13399 into account when calculating the initial malloc maximum.
13400 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13401 Move here from alloc.c, so that charset.c can use it too.
13402 Properly align; the old code wasn't right for common 32-bit hosts
13403 when configured with --enable-checking=all.
13404 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13405 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
13407 2011-09-29 Eli Zaretskii <eliz@gnu.org>
13409 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
13412 2011-09-28 Eli Zaretskii <eliz@gnu.org>
13414 * xdisp.c (compute_display_string_end): If there's no display
13415 string at CHARPOS, return -1.
13417 * bidi.c (bidi_fetch_char): When compute_display_string_end
13418 returns a negative value, treat the character as a normal
13419 character not covered by a display string. (Bug#9624)
13421 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
13423 * lread.c (Fread_from_string): Fix typo in docstring.
13425 2011-09-27 Eli Zaretskii <eliz@gnu.org>
13427 * xdisp.c (handle_invisible_prop): If invisible text ends on a
13428 newline, reseat the iterator instead of bidi-iterating there one
13429 character at a time. (Bug#9610)
13430 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
13431 TO_CHARPOS if the bidi iterator is at base embedding level.
13433 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
13435 * lread.c (readevalloop): Use correct code for NBSP.
13436 (read1): Likewise. (Bug#9608)
13438 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
13440 * dbusbind.c (Fdbus_register_signal): When service is not
13441 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
13443 2011-09-25 Glenn Morris <rgm@gnu.org>
13445 * buffer.c (truncate-lines): Doc fix.
13447 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
13449 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
13450 (Fset_window_next_buffers): Doc fix.
13452 2011-09-24 Glenn Morris <rgm@gnu.org>
13454 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
13456 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
13458 Fix minor problems found by static checking.
13459 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
13460 * indent.c (Fvertical_motion): Fix == vs = typo.
13462 2011-09-24 Eli Zaretskii <eliz@gnu.org>
13464 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
13465 Default value is now t. Doc fix.
13467 * indent.c (Fvertical_motion): Compute and apply the overshoot
13468 logic when moving up, not only when moving down. Fix the
13469 confusing name and values of the it_overshoot_expected variable;
13470 logic changes accordingly. (Bug#9254) (Bug#9549)
13472 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
13473 CHARPOS is covered by a display string which includes newlines.
13474 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
13475 is covered by a display string with embedded newlines.
13477 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
13479 * dbusbind.c (Fdbus_register_signal): Add match rule to
13480 Vdbus_registered_objects_table. (Bug#9581)
13481 (Fdbus_register_method, Vdbus_registered_objects_table):
13484 2011-09-24 Jim Meyering <meyering@redhat.com>
13486 do not ignore write error for any output size
13487 The previous change was incomplete.
13488 While it makes emacs --batch detect the vast majority of stdout
13489 write failures, errors were still ignored whenever the output size is
13490 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
13491 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
13492 && echo FAIL: ignored write error
13493 FAIL: ignored write error
13494 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
13495 && echo FAIL: ignored write error
13496 FAIL: ignored write error
13497 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
13499 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
13501 * emacs.c (Fkill_emacs): In noninteractive mode exit
13502 non-successfully if a write error occurred on stdout. (Bug#9574)
13504 2011-09-21 Eli Zaretskii <eliz@gnu.org>
13506 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
13509 * dispextern.h (struct it): Update the comment documenting what
13512 2011-09-20 Eli Zaretskii <eliz@gnu.org>
13514 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
13515 a display string, extend search for cursor position to end of row.
13516 (find_row_edges): If the row ends in a newline from a display
13517 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
13518 Handle the case of a display string with multiple newlines.
13519 (Fcurrent_bidi_paragraph_direction): Fix search for previous
13520 non-empty line. Fixes confusing cursor motion with arrow keys at
13521 the beginning of a line that starts with whitespace.
13523 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
13525 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
13528 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
13530 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
13531 boolean (Bug#9154).
13533 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13535 * xdisp.c (display_line): Record maximum and minimum buffer
13536 positions even if no glyphs were produced (e.g., by a zero-width
13537 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
13538 buffer positions that will be removed from the glyph row because
13540 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
13541 column is beyond frame width: don't subtract 1 "pixel" when
13542 computing width of the stretch.
13543 (reseat_at_next_visible_line_start): Undo the change made on
13544 2011-09-17 that saved paragraph information and restored it after
13545 the call to `reseat'. (Bug#9545)
13547 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13549 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
13550 and turn window cursor on if cleared (Bug#9415).
13552 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
13554 * search.c (boyer_moore): Take unibyte characters from pattern
13555 literally. (Bug#9458)
13557 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13559 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
13561 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
13563 Fix minor problem found by static checking.
13564 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
13565 initialized, to pacify gcc -Wuninitialized.
13567 * fileio.c: Report proper errno when syscall falls.
13568 (Finsert_file_contents): Save and restore errno,
13569 so that report_file_error outputs the correct diagnostic.
13570 (Fwrite_region) [CLASH_DETECTION]: Likewise.
13572 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13574 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
13576 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13578 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
13579 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
13581 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13583 * xdisp.c (reseat_at_next_visible_line_start): Keep information
13584 about the current paragraph and restore it after the call to reseat.
13586 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
13587 (bidi_find_paragraph_start): Search back for paragraph beginning
13588 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
13589 (bidi_move_to_visually_next): Only trigger paragraph-related
13590 computations when the last character is a newline or at EOB, not
13591 just any NEUTRAL_B. (Bug#9470)
13593 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
13594 truncated lines if point is covered by a display string. (Bug#9524)
13596 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
13598 * xselect.c: Relax test for outgoing X longs (Bug#9498).
13599 (cons_to_x_long): New function.
13600 (lisp_data_to_selection_data): Use it. Correct the test for
13601 short-versus-long data; it was negated. Break out of vector
13602 loop, for efficiency, when a long datum is discovered.
13604 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
13606 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
13608 2011-09-16 Eli Zaretskii <eliz@gnu.org>
13610 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
13611 GCC PR/17406) by declaring this function with external scope.
13613 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13615 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
13616 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
13618 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
13620 * editfns.c (Fformat): Correctly handle text properties on "%%".

13629 (fill_composite_glyph_string): Add comments about special meaning
13630 of TAB characters in a composition.
13632 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13634 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
13635 This occurs when processing a multibyte format.
13636 Problem reported by Wolfgang Jenker.
13638 2011-09-15 Johan Bockgård <bojohan@gnu.org>
13640 * xdisp.c (try_cursor_movement): Only check for exact match if
13641 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
13643 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13645 Remove unused external symbols.
13646 * dispextern.h (calc_pixel_width_or_height): Remove decl.
13647 * xdisp.c (calc_pixel_width_or_height): Now static.
13648 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
13649 * indent.c (check_display_width):
13650 * w32term.c: Fix comment to match code.
13651 * xterm.c, xterm.h (x_catching_errors): Remove.
13653 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13655 * xselect.c: Use signed conversions more consistently (Bug#9498).
13656 (selection_data_to_lisp_data): Assume incoming selection data are
13657 signed integers, not unsigned. This is to be consistent with
13658 outgoing selection data, which was modified to use signed integers
13659 in as part of the fix to Bug#9196 in response to Jan D.'s comment
13660 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
13661 expects long, not unsigned long.
13663 2011-09-14 Eli Zaretskii <eliz@gnu.org>
13665 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
13666 computation of loop end. Reported by Johan Bockgård
13669 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
13671 * frame.c (Fother_visible_frames_p): Function deleted.
13673 2011-09-12 Eli Zaretskii <eliz@gnu.org>
13675 * indent.c (compute_motion): Process display vector front to back
13676 rather than the other way around. (Bug#2496)
13678 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
13680 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
13682 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
13684 * minibuf.c (Fread_from_minibuffer): Doc fix.
13686 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13688 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
13689 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
13691 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
13693 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
13694 value for non-existent files.
13696 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13698 * fileio.c (Finsert_file_contents): If the file cannot be opened,
13699 set its "size" to -1. This will set the modtime_size field of
13700 the corresponding buffer to -1, which is what
13701 verify-visited-file-modtime expects for files that do not exist.
13704 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
13706 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
13708 * lisp.h: ... from here. push_key_description is no longer
13709 defined in keyboard.c, so its declaration should not be in
13710 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
13711 logically belongs with push_key_description.
13713 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
13715 * buffer.h: Include <sys/types.h> instead of <time.h>.
13716 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
13717 Problem reported by Herbert J. Skuhra.
13719 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
13721 * xml.c (parse_region): Make the parsing work for
13722 non-comment-starting XML files again (bug#9144).
13724 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
13726 * image.c (gif_load): Fix calculation of bottom and right corner.
13729 2011-09-10 Eli Zaretskii <eliz@gnu.org>
13731 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
13732 redisplay in small windows.
13734 2011-09-09 Eli Zaretskii <eliz@gnu.org>
13736 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
13738 2011-09-08 Martin Rudalics <rudalics@gmx.at>
13740 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
13741 Operate on live windows only.
13743 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
13745 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
13747 2011-09-07 Eli Zaretskii <eliz@gnu.org>
13749 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
13750 only under bidi iteration.
13752 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
13754 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
13756 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13758 isnan: Fix porting problem to Solaris 10 with bundled gcc.
13759 Without this fix, the command to link temacs failed due to an
13760 undefined symbol __builtin_isnan. This is because
13761 /usr/include/iso/math_c99.h #defines isnan(x) to
13762 __builtin_isnan(x), but the bundled gcc, which identifies itself
13763 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
13765 * floatfns.c (isnan): #undef, and then #define to a clone of
13767 (Fisnan): Always define, since it's always available now.
13768 (syms_of_floatfns): Always define isnan at the Lisp level.
13770 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13772 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
13774 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13776 * fileio.c: Fix bugs with large file offsets (Bug#9428).
13777 The previous code assumed that file offsets (off_t values) fit in
13778 EMACS_INT variables, which is not true on typical 32-bit hosts.
13779 The code messed up by falsely reporting buffer overflow in cases
13780 such as (insert-file-contents "big" nil 1 2) into an empty buffer
13781 when "big" contains more than 2**29 bytes, even though this
13782 inserts just one byte and does not overflow the buffer.
13783 (Finsert_file_contents): Store file offsets as off_t
13784 values, not as EMACS_INT values. Check for overflow when
13785 converting between EMACS_INT and off_t. When checking for
13786 buffer overflow or for overlap, take the offsets into account.
13787 Don't use EMACS_INT for small values where int suffices.
13788 When checking for overlap, fix a typo: ZV was used where
13789 ZV_BYTE was intended.
13790 (Fwrite_region): Don't assume off_t fits into 'long'.
13791 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
13793 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
13795 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
13797 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13799 sprintf-related integer and memory overflow issues (Bug#9412).
13801 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
13802 (esprintf, exprintf, evxprintf): New functions.
13803 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
13804 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
13805 (modify_event_symbol): Do not assume that the length of
13806 name_alist_or_stem is safe to alloca and fits in int.
13807 (Fexecute_extended_command): Likewise for function name and binding.
13808 (Frecursion_depth): Wrap around reliably on integer overflow.
13809 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
13810 since some callers pass EMACS_INT values.
13811 (Fsingle_key_description): Don't crash if symbol name contains more
13812 than MAX_ALLOCA bytes.
13813 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
13814 (get_minibuffer): Arg is now EMACS_INT, not int.
13815 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
13816 (esprintf, exprintf, evxprintf): New decls.
13817 * window.h (command_loop_level, minibuf_level): Reflect API changes.
13819 * dbusbind.c (signature_cat): New function.
13820 (xd_signature, Fdbus_register_signal):
13821 Do not overrun buffer; instead, report string overflow.
13823 * dispnew.c (add_window_display_history): Don't overrun buffer.
13824 Truncate instead; this is OK since it's just a log.
13826 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
13827 even if the time zone offset is outlandishly large.
13828 Don't mishandle offset == INT_MIN.
13830 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
13831 when creating daemon; the previous buffer-overflow check was incorrect.
13833 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
13834 which has the guts of the old verror function.
13836 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
13837 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
13839 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
13840 (font_unparse_xlfd): Don't blindly alloca long strings.
13841 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
13842 fits in int, when using sprintf. Use single snprintf to count
13843 length of string rather than counting it via multiple sprintfs;
13844 that's simpler and more reliable.
13845 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
13846 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
13847 sprintf, in case result does not fit in int.
13849 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
13850 (fontset_from_font): Print it.
13852 * frame.c (tty_frame_count): Now printmax_t, not int.
13853 (make_terminal_frame, set_term_frame_name): Print it.
13854 (x_report_frame_params): In X, window IDs are unsigned long,
13855 not signed long, so print them as unsigned.
13856 (validate_x_resource_name): Check for implausibly long names,
13857 and don't assume name length fits in 'int'.
13858 (x_get_resource_string): Don't blindly alloca invocation name;
13859 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
13862 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
13863 (xg_check_special_colors, xg_set_geometry):
13864 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
13866 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
13867 Use esprintf, not sprintf, in case result does not fit in int.
13869 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13870 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
13871 it as a large positive number.

13873 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13875 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
13876 in case result does not fit in int.
13878 * print.c (float_to_string): Detect width overflow more reliably.
13879 (print_object): Make sprintf buffer a bit bigger, to avoid potential
13880 buffer overrun. Don't assume list length fits in 'int'. Treat
13881 print length of 0 as 0, not as infinity; to be consistent with other
13882 uses of print length in this function. Don't overflow print length
13883 index. Don't assume hash table size fits in 'long', or that
13884 vectorlike size fits in 'unsigned long'.
13886 * process.c (make_process): Use printmax_t, not int, to format
13887 process-name gensyms.
13889 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
13891 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
13892 to avoid potential buffer overrun.
13894 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
13895 if X resource line is longer than 512 bytes.
13897 * xfns.c (x_window): Make sprintf buffer a bit bigger
13898 to avoid potential buffer overrun.
13900 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
13902 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
13904 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13906 Integer overflow fixes for scrolling, etc.
13907 Without these, Emacs silently mishandles large integers sometimes.
13908 For example, "C-u 4294967297 M-x recenter" was treated as if
13909 it were "C-u 1 M-x recenter" on a typical 64-bit host.
13911 * xdisp.c (try_window_id): Check Emacs fixnum range before
13912 converting to 'int'.
13914 * window.c (window_scroll_line_based, Frecenter):
13915 Check that an Emacs fixnum is in range before assigning it to 'int'.
13916 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
13917 values converted from Emacs fixnums.
13918 (Frecenter): Don't wrap around a line count if it is out of 'int'
13919 range; instead, treat it as an extreme value.
13920 (Fset_window_configuration, compare_window_configurations):
13921 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
13923 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
13924 that can exceed INT_MAX. Check that EMACS_INT value is in range
13925 before assigning it to the (possibly-narrower) index.
13926 (match_limit): Don't assume that a fixnum can fit in 'int'.
13928 * print.c (print_object): Use ptrdiff_t, not int, for index that can
13931 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
13932 (Fvertical_motion): Don't wrap around LINES values that don't fit
13933 in 'int'. Instead, treat them as extreme values. This is good
13934 enough for windows, which can't have more than INT_MAX lines anyway.
13936 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
13938 * Require libxml/parser.h to avoid compilation warning.
13940 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
13942 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
13943 since this reportedly can destroy thread storage.
13945 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
13947 * syntax.c (find_defun_start): Update all cache variables if
13948 exiting early (Bug#9401).
13950 2011-08-30 Eli Zaretskii <eliz@gnu.org>
13952 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
13954 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
13955 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
13956 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
13958 * term.c (tty_append_glyph): New function.
13959 (produce_stretch_glyph): Static function and its prototype deleted.
13961 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
13964 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
13966 * image.c (parse_image_spec): Check for nonnegative, not for positive,
13967 when checking :margin (Bug#9390).
13968 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
13969 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
13970 so that the name doesn't mislead. All uses changed.
13972 2011-08-28 Johan Bockgård <bojohan@gnu.org>
13974 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
13977 2011-08-27 Eli Zaretskii <eliz@gnu.org>
13979 * xdisp.c (move_it_to): Don't bail out early when reaching
13980 position beyond to_charpos, if we are scanning backwards.
13981 (move_it_vertically_backward): When DY == 0, make sure we get to
13982 the first character in the line after the newline.
13984 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
13986 * ccl.c: Improve and simplify overflow checking (Bug#9196).
13987 (ccl_driver): Do not generate an out-of-range pointer.
13988 (Fccl_execute_on_string): Remove unnecessary check for
13989 integer overflow, noted by Stefan Monnier in
13990 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
13991 Remove a FIXME that didn't need fixing.
13992 Simplify the newly-introduced buffer reallocation code.
13994 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
13996 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
13998 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
14000 Integer and memory overflow issues (Bug#9196).
14002 * doc.c (get_doc_string): Rework so that
14003 get_doc_string_buffer_size is the actual buffer size, rather than
14004 being 1 less than the actual buffer size; this makes xpalloc more
14007 * image.c (x_allocate_bitmap_record, cache_image):
14008 * xselect.c (Fx_register_dnd_atom):
14009 Simplify previous changes by using xpalloc.
14011 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
14012 since either will do and ptrdiff_t is convenient with xpalloc.
14014 * charset.c (charset_table_size)
14015 (struct charset_sort_data.priority): Now ptrdiff_t.
14016 (charset_compare): Don't overflow if priorities differ greatly.
14017 (Fsort_charsets): Don't assume list length fits in int.
14018 Check for size-calculation overflow when allocating sort data.
14019 (syms_of_charset): Allocate an initial charset table that is
14020 just under 64 KiB, to avoid problems with glibc malloc and mmap.
14022 * cmds.c (internal_self_insert): Check for size-calculation overflow.
14024 * composite.h (struct composition.glyph_len): Now int, not unsigned.
14025 The actual value is always <= INT_MAX, and leaving it unsigned made
14026 overflow checking harder.
14028 * dispextern.h (struct glyph_matrix.rows_allocated)
14029 (struct face_cache.size): Now ptrdiff_t, for convenience in use
14030 with xpalloc. The values are still always <= INT_MAX.
14032 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
14034 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
14035 (SAFE_NALLOCA): New macro.
14037 * region-cache.c (struct boundary.pos, find_cache_boundary)
14038 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
14039 (set_cache_region, invalidate_region_cache)
14040 (revalidate_region_cache, know_region_cache, region_cache_forward)
14041 (region_cache_backward, pp_cache):
14042 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
14043 so that ptrdiff_t * can be passed to xpalloc.
14044 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
14045 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
14046 (pp_cache): Don't assume cache_len fits in int.
14047 * region-cache.h: Adjust extern decls to match.
14049 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
14050 EMACS_INT, since either will do, for xpalloc.
14052 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
14053 (xnmalloc, xnrealloc, xpalloc): New functions.
14055 * bidi.c (bidi_shelve_header_size): New constant.
14056 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
14057 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
14059 * bidi.c (bidi_cache_shrink):
14060 * buffer.c (overlays_at, overlays_in, record_overlay_string)
14062 Don't update size of array until after memory allocation succeeds,
14063 because xmalloc/xrealloc may not return.
14064 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
14065 now that we have proper integer overflow checking.
14066 (record_overlay_string, overlay_strings): Catch overflows when
14067 calculating size of overlay_str_buf.
14069 * callproc.c (Fcall_process): Check for size overflow when
14070 calculating size of args2.
14071 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
14072 Normally we prefer signed values, but sticking with ptrdiff_t would
14073 require adding more-complicated checks.
14075 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
14076 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
14077 Redo buffer-overflow calculations to avoid integer overflow.
14078 Add a FIXME comment where memory seems to be over-allocated.
14080 * character.c (Fstring): Check for size-calculation overflow.
14082 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
14083 unnecessary integer overflow. Check for size overflow.
14084 (encode_coding_object): Don't update size until xmalloc succeeds.
14086 * composite.c (get_composition_id): Check for overflow in glyph
14087 length calculations.
14089 Integer and memory overflow fixes for display code.
14090 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
14091 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
14092 (scrolling_window): Check for overflow in size calculations.
14093 (line_draw_cost, realloc_glyph_pool, add_row_entry):
14094 Don't assume glyph table len fits in int.

14096 (row_table_size): Now ptrdiff_t, not int.
14097 (scrolling_window): Avoid overflow in size calculations.
14098 Don't update size until allocation succeeds.
14099 * fns.c (concat): Check for overflow in size calculations.
14100 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
14101 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.

14104 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
14105 (get_doc_string): Check for size calculation overflow.
14106 Don't update size until allocation succeeds.
14107 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
14108 EMACS_INT, where ptrdiff_t will do.
14109 (Fsubstitute_command_keys): Check for string overflow.
14111 * editfns.c (set_time_zone_rule): Don't assume environment length
14113 (message_length): Now ptrdiff_t, not int.
14114 (Fmessage_box): Don't update size until allocation succeeds.
14115 Don't assume message length fits in int.
14116 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
14118 * emacs.c (main): Do not reallocate argv, since there is a null at
14119 the end that can be overwritten, and this way there's no need to
14120 worry about size-calculation overflow.
14121 (sort_args): Check for size-calculation overflow.
14123 * eval.c (init_eval_once, grow_specpdl): Don't update size until
14125 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
14127 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
14128 (x_set_scroll_bar_width, x_figure_window_size):
14129 Check for integer overflow.
14130 (x_set_alpha): Do not assume XINT fits in int.
14132 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
14133 This is for the members text_lines, text_cols, total_lines, total_cols,
14134 where the system imposes an 'int' limit.
14136 * fringe.c (Fdefine_fringe_bitmap):
14137 Don't update size until alloc works.
14139 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
14140 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
14142 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
14143 Check for size-calculation overflow.
14144 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
14145 do, as we prefer signed integers.
14146 (id_to_widget.max_size, id_to_widget.used)
14147 (xg_store_widget_in_map, xg_remove_widget_from_map)
14148 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
14149 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
14150 Use and return ptrdiff_t, not int.
14151 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
14152 * gtkutil.h: Change prototypes to match the above.
14154 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
14155 are duplicate now that they've been promoted to lisp.h.
14156 (x_allocate_bitmap_record, x_alloc_image_color)
14157 (make_image_cache, cache_image, xpm_load):
14158 Don't update size until alloc is done.
14159 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
14161 Check for size calculation overflow.
14162 (ct_colors_allocated_max): New constant.
14163 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
14166 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
14167 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
14168 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
14169 Use ptrdiff_t, not int, to count maps.
14170 (read_char_minibuf_menu_prompt): Check for overflow in size
14171 calculations. Don't update size until allocation succeeds.
14172 Redo calculations to avoid overflow.
14173 * keyboard.h: Change prototypes to match the above.
14175 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
14177 (current_minor_maps): Check for size calculation overflow.
14178 * keymap.h: Change prototypes to match the above.
14180 * lread.c (read1, init_obarray): Don't update size until alloc done.
14182 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
14183 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
14185 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
14186 Now ptrdiff_t, not int.
14187 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.
14188 (ns_draw_fringe_bitmap): Rewrite to avoid overflow.

14191 in size calculation.
14193 * region-cache.c (move_cache_gap): Check for size calculation overflow.
14195 * scroll.c (do_line_insertion_deletion_costs): Check for size calc
14196 overflow. Don't bother calling xmalloc when xrealloc will do.
14198 * search.c (Freplace_match): Check for size calculation overflow.
14199 (Fset_match_data): Don't assume list lengths fit in 'int'.
14201 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
14202 for command line length. Do not attempt to address one before the
14203 beginning of an array, as that's not portable.
14205 * term.c (max_frame_lines): Remove; unused.
14206 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
14208 (encode_terminal_code, calculate_costs): Check for size
14209 calculation overflow.
14210 (encode_terminal_code): Use ptrdiff_t, not int, to record glyph
14211 table lengths and related sizes. Don't update size until alloc
14212 done. Redo calculations to avoid overflow.
14213 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
14215 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
14216 subtracting pointers.
14217 (gobble_line): Check for overflow more carefully. Don't update size
14220 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
14221 Don't update size until alloc done.
14222 Redo size calculations to avoid overflow.

14224 (main) [DEBUG]: Fix typo in invoking tparam1.
14226 * xdisp.c (store_mode_line_noprop_char, x_consider_frame_title):
14227 Use ptrdiff_t, not int, for sizes.
14228 (store_mode_line_noprop_char): Don't update size until alloc done.
14230 * xfaces.c (lface_id_to_name_size, Finternal_make_lisp_face):
14231 Use ptrdiff_t, not int, for sizes.
14232 (Finternal_make_lisp_face, cache_face):
14233 Check for size calculation overflow.
14234 (cache_face): Treat size calculation overflows as if they were
14235 memory exhaustion (the usual treatment), rather than aborting.
14237 * xfns.c (x_encode_text, x_set_name_internal)
14238 (Fx_change_window_property): Use ptrdiff_t, not int, to count
14239 sizes, since they can exceed INT_MAX in size. Check for size
14240 calculation overflow.
14242 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
14243 (xg_select): Check for size calculation overflow.
14244 Don't update size until alloc done.
14246 * xrdb.c (get_environ_db): Don't assume path length fits in int,
14247 as sprintf is limited to int lengths.
14249 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
14250 (X_LONG_MIN): New macros.
14251 Use them to make the following changes clearer.
14252 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
14253 This change doesn't affect the value now, but it may help remind
14254 future maintainers not to raise the value too much later.
14255 (SELECTION_QUANTUM): Remove, replacing with ...
14256 (selection_quantum): ... new function, which avoids overflow.
14258 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
14259 assumption that selection length fits in 'int'.
14260 (x_reply_selection_request, x_handle_selection_request)
14261 (x_get_window_property, receive_incremental_selection)
14262 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
14263 (lisp_data_to_selection_data, clean_local_selection_data):
14264 Use ptrdiff_t, not int, to record length of selection.
14265 (x_reply_selection_request, x_get_window_property)
14266 (receive_incremental_selection, x_property_data_to_lisp):
14267 Redo calculations to avoid overflow.
14268 (x_reply_selection_request): When sending hint, ceiling it at
14269 X_LONG_MAX rather than relying on wraparound overflow to send
14271 (x_get_window_property, receive_incremental_selection)
14272 (lisp_data_to_selection_data, x_property_data_to_lisp):
14273 Check for size-calculation overflow.
14274 (x_get_window_property, receive_incremental_selection)
14275 (lisp_data_to_selection_data, Fx_register_dnd_atom):
14276 Don't store size until memory allocation succeeds.
14277 (x_get_window_property): Plug memory leak on memory exhaustion.
14278 Don't double-block input; malloc is safe here. Don't assume 2**34
14279 - 4 fits in unsigned long. Add an xassert to check
14280 XGetWindowProperty overflow. Be more careful about overflow
14281 calculations, and distinguish size from memory overflow better.
14282 (receive_incremental_selection): When tracing, don't assume
14283 unsigned int is less than INT_MAX.
14284 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
14285 harmful) conversions of unsigned short to int.
14286 (lisp_data_to_selection_data): Don't assume that integers
14287 in the range -65535 through -1 fit in an X unsigned short.
14288 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
14289 result parameters unless successful. Rely on cons_to_unsigned
14290 to report problems with elements; the old code wasn't right anyway.
14291 (x_check_property_data): Check for int overflow; we cannot use
14292 a wider type due to X limits.

14325 * lisp.h (hash_lookup, hash_put):
14326 * minibuf.c (Ftest_completion):
14327 Use ptrdiff_t for hash table indexes, not int (which is too
14328 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
14329 32-bit --with-wide-int hosts).
14331 * charset.c (Fdefine_charset_internal): Check for integer overflow.
14332 Add a FIXME comment about memory leaks.
14333 (syms_of_charset): Don't assume xmalloc returns.

14340 with outlandish widths.
14341 * character.h (sanitize_tab_width): Rename from sanitize_width,
14342 now that we have two such functions. All uses changed.

14360 * xterm.c: Don't go over XClientMessageEvent limit.
14361 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
14362 (x_send_scroll_bar_event): Likewise. Check that the size does not
14363 exceed limits imposed by XClientMessageEvent, as well as the usual
14364 ptrdiff_t and size_t limits.
14366 * keyboard.c: Overflow, signedness and related fixes.
14367 (make_lispy_movement): Use same integer type in forward decl
14368 that is used in the definition.
14369 (read_key_sequence, keyremap_step):
14370 Change bufsize argument back to int, undoing my 2011-03-30 change.
14371 We prefer signed types, and int is wide enough here.
14372 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
14373 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
14374 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
14375 length, not size_t. Use ptrdiff_t for index, not int.
14376 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
14377 possibility of integer overflow.
14379 Overflow, signedness and related fixes for images.

14403 since parse_image_check makes sure they fit into int.
14404 (png_load, gif_load, svg_load_image):
14405 Prefer int to unsigned where either will do.
14406 (tiff_handler): New function, combining the cores of the
14407 old tiff_error_handler and tiff_warning_handler.
14408 This function is rewritten to use vsnprintf and thereby avoid
14409 stack buffer overflows. It uses only the features of vsnprintf
14410 that are common to both POSIX and native Microsoft.
14411 (tiff_error_handler, tiff_warning_handler): Use it.
14412 (tiff_load, gif_load, imagemagick_load_image):
14413 Don't assume :index value fits in 'int'.
14414 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
14415 (imagemagick_load_image): Check that crop parameters fit into
14416 the integer types that MagickCropImage accepts. Don't assume
14417 Vimagemagick_render_type has a nonnegative value. Don't assume
14418 size_t fits in 'long'.
14419 (gs_load): Use printmax_t to print the widest integers possible.

14433 (handle_single_display_spec): If the display spec is of the form
14434 `(space ...)', and specifies display in the text area, return 2
14436 (try_cursor_movement): Check for the need to scroll more
14437 accurately, and prefer exact match for point under bidi.
14438 Don't advance `row' beyond the last row of the window.

14455 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
14456 buffers, return left-to-right.
14457 (set_cursor_from_row): Consider candidate row a win if its glyph
14458 represents a newline and point is on that newline. Fixes cursor
14459 positioning on the newline at EOL of R2L text within L2R
14460 paragraph, and vice versa.
14461 (try_cursor_movement): Check continued rows, in addition to
14462 continuation rows. Fixes unwarranted scroll when point enters a
14463 continued line of R2L text within an L2R paragraph, or vice versa.
14464 (cursor_row_p): Consider the case of point being equal to
14465 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
14466 from the end of a short line to the beginning of a continued line
14467 of R2L text within L2R paragraph.
14468 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

14487 extra slot even if the purpose is char-code-property-table.
14489 2011-08-23 Eli Zaretskii <eliz@gnu.org>
14491 * xdisp.c (redisplay_window): When computing centering_position,
14492 account for the height of the header line. (Bug#8874)
14494 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
14495 instead of CHAR_TO_BYTE. Fixes a crash when a completion
14496 candidate is selected by the mouse, and that candidate has a
14497 composed character under the mouse.
14499 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
14500 coordinates reported by pos-visible-in-window-p for a composed
14501 character in column zero.
14503 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

14507 2011-08-22 Eli Zaretskii <eliz@gnu.org>
14509 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
14510 consider it a hit if to_charpos is anywhere in the range of the
14511 composed buffer positions.
14513 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
14515 * image.c (gif_load): Don't assume that each subimage has the same
14516 dimensions as the base image. Handle disposal method that is
14517 "undefined" by the gif spec (Bug#9335).
14519 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
14521 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

14524 2011-08-19 Eli Zaretskii <eliz@gnu.org>
14526 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
14527 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
14528 from an Org mode buffer to a Speedbar frame.
14530 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
14531 a composition, take its buffer position from IT->cmp_it.charpos.
14532 Fixes cursor positioning at the beginning of a line that begins
14533 with a composed character.
14535 2011-08-18 Eli Zaretskii <eliz@gnu.org>
14537 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
14538 character bidirectional type, use STRONG_L instead. Fixes crashes
14539 in a buffer produced by `describe-categories'.
14541 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
14542 members before the level stack, so they would be saved and
14543 restored when copying iterator state. Fixes incorrect reordering
14544 around TABs covered by display properties.
14546 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
14548 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

14613 * process.c (create_process): Call setup_process_coding_systems
14614 after the pid of the process is set to -1 (Bug#8162).
14616 2011-08-14 Eli Zaretskii <eliz@gnu.org>
14618 * xdisp.c (move_it_in_display_line_to): Don't invoke
14619 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
14620 ppos_it. Fixes vertical cursor motion when line beginning is
14621 covered by an image. (Bug#9296)
14623 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
14625 * nsterm.h (ns_run_ascript): Declare.

14629 (ns_run_ascript): New function.
14630 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
14631 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
14632 the event loop. Get status from as_status (Bug#7276).
14634 * nsterm.m (sendEvent): If event is NSApplicationDefined and
14635 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
14636 the event loop (Bug#7276).
14638 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>

14662 (Fnetwork_interface_list): Allocate in increments of bytes instead
14663 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
14664 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
14666 (struct ifflag_def): notrailers is smart on OSX.
14667 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
14668 Get hardware address with getifaddrs if available.
14670 2011-08-12 Eli Zaretskii <eliz@gnu.org>
14672 * xdisp.c (iterate_out_of_display_property): xassert that
14673 IT->position is set to within IT->object's boundaries. Break from
14674 the loop as soon as EOB is reached; avoids infloops in redisplay

14676 Set IT->current to match the bidi iterator unconditionally.
14677 (push_display_prop): Allow GET_FROM_STRING as IT->method on
14678 entry. Force push_it to save on the stack the current
14679 buffer/string position, to be restored by pop_it. Fix flags in
14680 the iterator structure wrt the object coming from a display
14681 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
14682 properties. (Bug#9284)
14684 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
14686 * fontset.c (fontset_get_font_group): Add proper type checks.

14711 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
14713 * composite.c (autocmp_chars): Don't reset point. That is done by
14714 restore_point_unwind (Bug#5984).
14716 2011-08-07 Juri Linkov <juri@jurta.org>
14718 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
14719 to show the arg `TIME' instead of `TIMEVAL'.
14721 2011-08-06 Eli Zaretskii <eliz@gnu.org>
14723 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
14724 display property strides EOL and includes a newline, as in
14725 longlines-mode. (Bug#9254)
14726 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
14727 word-wrap under bidirectional display. (Bug#9224)
14729 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
14730 is non-zero, even if the data buffer is NULL. Fixes a crash in
14731 vertical-motion with longlines-mode. (Bug#9254)
14733 2011-08-05 Eli Zaretskii <eliz@gnu.org>
14735 * bidi.c <bidi_cache_total_alloc>: Now static.
14736 (bidi_initialize): Initialize bidi_cache_total_alloc.
14738 * xdisp.c (display_line): Release buffer allocated for shelved bidi
14741 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
14742 amount allocated this far in `bidi_cache_total_alloc'.
14743 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
14744 non-zero, only free the data buffer without restoring the cache
14745 contents. All callers changed.
14747 * dispextern.h (bidi_unshelve_cache): Update prototype.
14749 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
14750 (move_it_in_display_line, move_it_to)
14751 (move_it_vertically_backward, move_it_by_lines): Replace the call
14752 to xfree to an equivalent call to bidi_unshelve_cache.
14753 (move_it_in_display_line_to): Fix logic of returning
14754 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
14756 2011-08-05 Eli Zaretskii <eliz@gnu.org>
14758 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
14759 came from a string character with a `cursor' property. (Bug#9229)
14761 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
14763 * Makefile.in (LIB_PTHREAD): New variable.
14764 (LIBES): Add LIB_PTHREAD (Bug#9216).
14766 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
14767 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
14769 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
14771 * regex.c (re_iswctype): Remove some redundant boolean conversions.
14773 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
14775 * xterm.c (x_find_topmost_parent): New function.
14776 (x_set_frame_alpha): Find topmost parent window with
14777 x_find_topmost_parent and set the property there also (bug#9181).
14778 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
14780 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
14782 * callproc.c (Fcall_process): Avoid vfork clobbering
14783 the local vars buffer, coding_systems, current_dir.
14785 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
14787 * keymap.c (Fmake_composed_keymap): Move to subr.el.
14789 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
14791 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
14792 so that it is not optimized away.
14794 * xdisp.c (compute_display_string_pos): Remove unused local.
14796 2011-08-02 Eli Zaretskii <eliz@gnu.org>
14798 Fix slow cursor motion and scrolling in large buffers with
14799 selective display, like Org Mode buffers. (Bug#9218)
14801 * dispextern.h (struct bidi_it): New member disp_prop_p.
14803 * xdisp.c: Remove one-slot cache of display string positions.
14804 (compute_display_string_pos): Accept an additional argument
14805 DISP_PROP_P; callers changed. Scan at most 5K characters forward
14806 for a display string or property. If found, set DISP_PROP_P
14809 * bidi.c (bidi_fetch_char): Accept an additional argument
14810 DISP_PROP_P, and pass it to compute_display_string_pos.
14811 Only handle text covered by a display string if DISP_PROP_P is returned
14812 non-zero. All callers of bidi_fetch_char changed.
14814 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
14816 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
14818 2010-12-03 Don March <don@ohspite.net>
14820 * keymap.c (Fdefine_key): Fix non-prefix key error message when
14821 last character M-[char] is translated to ESC [char] (bug#7541).
14823 2011-08-02 Kenichi Handa <handa@m17n.org>
14825 * lisp.h (uniprop_table): Extern it.
14827 * chartab.c (uniprop_table): Make it non-static.
14829 2011-08-01 Eli Zaretskii <eliz@gnu.org>
14831 * xdisp.c (forward_to_next_line_start): Accept additional argument
14832 BIDI_IT_PREV, and store into it the state of the bidi iterator had
14834 (reseat_at_next_visible_line_start): Use the bidi iterator state
14835 returned by forward_to_next_line_start to restore the state of
14836 it->bidi_it after backing up to previous newline. (Bug#9212)
14838 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
14840 * regex.c (re_comp): Protoize.
14841 (re_exec): Fix return type.
14842 (regexec): Fix type of `ret'. (Bug#9203)
14844 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14846 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
14847 This is needed if max-image-size is a floating-point number.
14849 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
14851 * print.c (print_object): Print empty symbol as ##.
14853 * lread.c (read1): Read ## as empty symbol.
14855 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
14857 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
14858 setting frame foreground color (Bug#9175).
14859 (x_set_background_color): Likewise.
14861 * nsmenu.m (-setText): Size tooltip dimensions precisely to
14862 contents (Bug#9176).
14863 (EmacsTooltip -init): Remove bezels and add shadows to
14866 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
14867 or scroll bar (Bug#8470).
14869 * nsfont.m (nsfont_open): Remove assignment to voffset and
14870 unnecessary vars hshink, expand, hd, full_height, min_height.
14871 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
14873 * nsterm.h (nsfont_info): Remove voffset field.
14875 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
14877 Implement strike-through and overline on NextStep (Bug#8863).
14879 * nsfont.m (nsfont_open): Use underline position provided by font,
14880 instead of hard-coded value of 2.
14881 (nsfont_draw): Call ns_draw_text_decoration instead.
14883 * nsterm.h: Add declaration for ns_draw_text_decoration.
14885 * nsterm.m (ns_draw_text_decoration): New function for drawing
14886 underline, overline, and strike-through.
14887 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
14888 ns_draw_text_decoration. Change treatment of cursor drawing to
14889 accommodate underlining, etc.
14891 2011-07-28 Eli Zaretskii <eliz@gnu.org>
14893 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
14896 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14898 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
14899 Without this fix, if a signal arrives just after memory fills up,
14900 'malloc' might be invoked reentrantly.
14902 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
14903 In other words, assume that every image size is allowed, on non-X
14904 hosts. This assumption is probably wrong, but it lets Emacs compile.
14906 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
14908 * regex.c (re_iswctype): Convert return values to boolean.
14910 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
14912 * xdisp.c (compute_display_string_pos): Don't use cached display
14913 string position if the buffer had its restriction changed.
14916 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14918 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
14920 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14922 Integer signedness and overflow and related fixes. (Bug#9079)
14924 * bidi.c: Integer size and overflow fixes.
14925 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
14926 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
14927 (bidi_cache_find_level_change, bidi_cache_ensure_space)
14928 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
14929 (bidi_find_other_level_edge):
14930 Use ptrdiff_t instead of EMACS_INT where either will do.
14931 This works better on 32-bit hosts configured --with-wide-int.
14932 (bidi_cache_ensure_space): Check for size-calculation overflow.
14933 Use % rather than repeated addition, for better worst-case speed.
14934 Don't set bidi_cache_size until after xrealloc returns, because it
14936 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
14937 (bidi_cache_ensure_space): Also check that the bidi cache size
14938 does not exceed that of the largest Lisp string or buffer. See Eli
14939 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
14941 * alloc.c (__malloc_size_t): Remove.
14942 All uses replaced by size_t. See Andreas Schwab's note
14943 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
14945 * image.c: Improve checking for integer overflow.
14946 (check_image_size): Assume that f is nonnull, since
14947 it is always nonnull in practice. This is one less thing to
14948 worry about when checking for integer overflow later.
14949 (x_check_image_size): New function, which checks for integer
14950 overflow issues inside X.
14951 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
14952 This removes the need for a memory_full check.
14953 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
14954 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
14955 (xbm_read_bitmap_data): Change locals back to 'int', since
14956 their values must fit in 'int'.
14957 (xpm_load_image, png_load, tiff_load):
14958 Invoke x_create_x_image_and_pixmap earlier,
14959 to avoid much needless work if the image is too large.
14960 (tiff_load): Treat overly large images as if
14961 x_create_x_image_and_pixmap failed, not as malloc failures.
14962 (gs_load): Use x_check_image_size.
14964 * gtkutil.c: Omit integer casts.
14965 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
14966 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
14968 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
14970 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
14971 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
14972 would wrongly return t on a 64-bit host.
14974 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
14975 The plain *_OVERFLOW macros run afoul of GCC bug 49705
14976 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
14977 and therefore cause GCC to emit a bogus diagnostic in some cases.
14979 * image.c: Integer signedness and overflow and related fixes.
14980 This is not an exhaustive set of fixes, but it's time to
14981 record what I've got.
14982 (lookup_pixel_color, check_image_size): Remove redundant decls.
14983 (check_image_size): Don't assume that arbitrary EMACS_INT values
14984 fit in 'int', or that arbitrary 'double' values fit in 'int'.
14985 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
14986 (tiff_load, imagemagick_load_image):
14987 Check for overflow in size calculations.
14988 (x_create_x_image_and_pixmap): Remove unnecessary test for
14989 xmalloc returning NULL; that can't happen.
14990 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
14991 (xpm_color_bucket): Use better integer hashing function.
14992 (xpm_cache_color): Don't possibly over-allocate memory.
14993 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
14994 (gif_memory_source):
14995 Use ptrdiff_t, not int or size_t, to record sizes.
14996 (png_load): Don't assume values greater than 2**31 fit in 'int'.
14997 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
14998 either works, as we prefer signed integers.
14999 (tiff_read_from_memory, tiff_write_from_memory):
15000 Return tsize_t, not size_t, since that's what the TIFF API wants.
15001 (tiff_read_from_memory): Don't fail simply because the read would
15002 go past EOF; instead, return a short read.
15003 (tiff_load): Omit no-longer-needed casts.
15004 (Fimagemagick_types): Don't assume size fits into 'int'.
15006 Improve hashing quality when configured --with-wide-int.
15007 * fns.c (hash_string): New function, taken from sxhash_string.
15008 Do not discard information about ASCII character case; this
15009 discarding is no longer needed.
15010 (sxhash-string): Use it. Change sig to match it. Caller changed.
15011 * lisp.h: Declare it.
15012 * lread.c (hash_string): Remove, since we now use fns.c's version.
15013 The fns.c version returns a wider integer if --with-wide-int is
15014 specified, so this should help the quality of the hashing a bit.
15016 * emacs.c: Integer overflow minor fix.
15017 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
15018 Define only if GNU_LINUX.
15019 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
15021 * dispnew.c: Integer signedness and overflow fixes.
15022 Remove unnecessary forward decls, that were a maintenance hassle.
15023 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
15025 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
15026 (scrolling_window): Use ptrdiff_t, not int, for byte count.
15027 (prepare_desired_row, line_draw_cost):
15028 Use int, not unsigned, where either works.
15029 (save_current_matrix, restore_current_matrix):
15030 Use ptrdiff_t, not size_t, where either works.
15031 (init_display): Check for overflow more accurately, and without
15032 relying on undefined behavior.
15034 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
15035 Remove, replacing with the new symbols in lisp.h. All uses changed.
15036 * fileio.c (make_temp_name):
15037 * filelock.c (lock_file_1, lock_file):
15038 * xdisp.c (message_dolog):
15039 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
15040 Use pMd etc. instead.
15041 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
15042 replacing the pWIDE etc. symbols removed from editfns.c.
15044 * keyboard.h (num_input_events): Now uintmax_t.
15045 This is (very slightly) less likely to mess up due to wraparound.
15048 * buffer.c: Integer signedness fixes.
15049 (alloc_buffer_text, enlarge_buffer_text):
15050 Use ptrdiff_t rather than size_t when either will do, as we prefer
15053 * alloc.c: Integer signedness and overflow fixes.
15054 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
15055 (__malloc_size_t): Default to size_t, not to int.
15056 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
15057 (Fgarbage_collect, mark_object_loop_halt, mark_object):
15058 Prefer ptrdiff_t to size_t when either would do, as we prefer
15060 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
15061 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
15062 Now const. Initialize with values that are in range even if char
15064 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
15065 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
15066 These functions do the right thing with sizes > 2**32.
15067 (check_depth): Now ptrdiff_t, not int.
15068 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
15069 Adjust to new way of storing sizes. Check for size overflow bugs
15071 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
15072 slightly wrong anyway, as it missed one instance of
15073 XMALLOC_OVERRUN_CHECK_OVERHEAD.
15074 (refill_memory_reserve): Omit needless cast to size_t.
15075 (mark_object_loop_halt): Mark as externally visible.
15077 * xselect.c: Integer signedness and overflow fixes.
15078 (Fx_register_dnd_atom, x_handle_dnd_message):
15079 Use ptrdiff_t, not size_t, since we prefer signed.
15080 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
15081 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
15082 x_dnd_atoms_size and x_dnd_atoms_length.
15084 * doprnt.c: Prefer signed to unsigned when either works.
15086 * doprnt.c (doprnt):
15088 * xdisp.c (vmessage):
15089 Use ptrdiff_t, not size_t, when using or implementing doprnt,
15090 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
15091 prefer signed arithmetic to avoid comparison confusion.
15092 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
15093 but is a bit tricky.
15095 Assume freestanding C89 headers, string.h, stdlib.h.
15096 * data.c, doprnt.c, floatfns.c, print.c:
15097 Include float.h unconditionally.
15098 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
15099 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
15100 * regex.c: Likewise for stddef.h, string.h.
15101 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
15102 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
15103 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
15104 (STDC_HEADERS): Remove obsolete defines.
15105 * sysdep.c: Include limits.h unconditionally.
15107 Assume support for memcmp, memcpy, memmove, memset.
15108 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
15109 * regex.c (memcmp, memcpy):
15110 Remove; we assume C89 now.
15112 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
15113 (__malloc_safe_bcopy): Remove; no longer needed.
15115 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
15116 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
15117 well either way, and we prefer signed to unsigned.
15119 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
15121 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
15122 closes the connection while we're reading (bug#9182).
15124 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
15126 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
15127 are specified (Bug#9168).
15129 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
15131 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
15132 Found by GCC static checking and --with-wide-int on a 32-bit host.
15134 2011-07-25 Eli Zaretskii <eliz@gnu.org>
15136 * xdisp.c (compute_display_string_pos): Fix logic of caching
15137 previous display string position. Initialize cached_prev_pos to
15138 -1. Fixes slow-down at the beginning of a buffer.
15140 2011-07-24 Eli Zaretskii <eliz@gnu.org>
15142 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
15143 for attrs[LFACE_FONTSET_INDEX].
15145 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
15147 * xml.c (parse_region): Remove unused local
15148 that was recently introduced.
15150 2011-07-23 Eli Zaretskii <eliz@gnu.org>
15152 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
15153 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
15155 * xdisp.c (move_it_in_display_line_to): Record the best matching
15156 position for TO_CHARPOS while scanning the line, and restore it on
15157 exit if none of the characters scanned was an exact match.
15158 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
15159 when exact match is impossible due to invisible text, and the
15160 lines are truncated.
15162 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
15164 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
15167 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15169 Fix a significant slow-down of cursor motion with C-n, C-p,
15170 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
15171 auto-repeat under bidi redisplay in fontified buffers.
15172 * xdisp.c (compute_stop_pos_backwards): New function.
15173 (next_element_from_buffer): Call compute_stop_pos_backwards to
15174 find a suitable prev_stop when we find ourselves before
15176 (reseat): Don't look for prev_stop, as that could mean a very long
15178 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
15179 <cached_disp_overlay_modiff>: Cache for last found display string
15181 (compute_display_string_pos): Return the cached position if asked
15182 about the same buffer in the same area of character positions, and
15183 the buffer wasn't changed since the time the display string
15184 position was cached.
15186 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15188 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
15189 is an integer, which is important for empty lines. (Bug#9149)
15191 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
15193 * frame.c (Fmodify_frame_parameters): In tty case, update the
15194 default face if necessary (Bug#4238).
15196 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
15198 * editfns.c (Fstring_to_char): No need to explain what a character
15199 is in the docstring (Bug#6576).
15201 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15203 * xml.c (parse_region): Make sure we always return a tree.
15205 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
15207 * xml.c (parse_region): If a document contains only comments,
15210 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15212 * xml.c (make_dom): Return comments, too.

15217 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
15218 and the surrounding thread.
15219 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
15220 rather than fgets, and retry after EINTR. Otherwise, 'emacs
15221 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
15223 * s/openbsd.h (BROKEN_SIGIO): Define.
15224 * unexelf.c (unexec) [__OpenBSD__]:
15225 Don't update the .mdebug section of the Alpha COFF symbol table.
15227 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15229 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
15232 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
15234 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
15235 This fixes some race conditions on the permissions of any newly
15238 * alloc.c (valid_pointer_p): Use pipe, not open.
15239 This fixes some permissions issues when debugging.
15241 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
15242 If fchown fails to set both uid and gid, try to set just gid,
15243 as that is sometimes allowed. Adjust the file's mode to eliminate
15244 setuid or setgid bits that are inappropriate if fchown fails.
15246 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
15248 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
15249 to compare Lisp_Objects.

15254 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
15256 * lread.c (read_integer): Unread even EOF character.
15257 (read1): Likewise. Properly record start position of symbol.

15260 symbol character follows.
15262 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
15264 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
15265 This works around a problem with the previous change to Fcopy_file.
15266 Recent glibc declares fchown with __attribute__((warn_unused_result)),
15267 and without this change, GCC might complain about discarding
15268 fchown's return value.
15270 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
15272 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
15274 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
15276 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
15278 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
15280 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
15281 it's used from the C level.
15283 * process.c: Use the same condition for POLL_FOR_INPUT in both
15284 keyboard.c and process.c (bug#1858).
15286 2011-07-09 Lawrence Mitchell <wence@gmx.li>
15288 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
15289 (Fgnutls_boot): Use it.
15291 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
15293 * doc.c (Fsubstitute_command_keys): Revert last change.
15295 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
15297 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
15298 quotes the next character, and doesn't affect other longer
15299 sequences (bug#8935).
15301 * lread.c (syms_of_lread): Clarify that is isn't only
15302 `eval-buffer' and `eval-defun' that's affected by
15303 `lexical-binding' (bug#8460).
15305 2011-07-15 Eli Zaretskii <eliz@gnu.org>
15307 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
15308 bidi redisplay when a line includes both an image and is truncated.
15310 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
15312 Fix minor problems found by static checking.
15313 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
15314 (elsz): Now a signed constant, not a size_t var. We prefer signed
15315 types to unsigned, to avoid integer comparison confusion. Without
15316 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
15317 "cannot optimize loop, the loop counter may overflow", a symptom
15319 * indent.c (Fvertical_motion): Mark locals as initialized.
15320 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
15322 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>

15348 (display_string): If we need to ignore text properties of
15349 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
15350 original value of -1 will not work with bidi.)
15351 (compute_display_string_pos): First arg is now struct
15352 `text_pos *'; all callers changed. Support display properties on
15354 (compute_display_string_end): Support display properties on Lisp
15356 (init_iterator, reseat_1, reseat_to_string): Initialize the
15357 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
15358 when iterating on a string not from display properties).
15359 (compute_display_string_pos, compute_display_string_end):
15360 Fix calculation of the object to scan. Fixes an error when using
15362 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
15363 base_level_stop; instead, set base_level_stop to BEGV.
15364 Fixes crashes in vertical-motion.
15365 (next_element_from_buffer): Improve commentary for when
15366 the iterator is before prev_stop.
15367 (init_iterator): Initialize bidi_p from the default value of
15368 bidi-display-reordering, not from buffer-local value. Use the
15369 buffer-local value only if initializing for buffer iteration.
15370 (handle_invisible_prop): Support invisible properties on strings
15371 that are being bidi-reordered.

15390 parts of next_element_from_buffer, next_element_from_string, and
15391 next_element_from_c_string.
15392 (tool_bar_lines_needed, redisplay_tool_bar)
15393 (display_menu_bar): Force left-to-right direction. Add a FIXME
15394 comment for making that be controlled by a user option.

15403 (get_overlay_strings_1, push_display_prop): Set up the bidi
15404 iterator for displaying display or overlay strings.
15405 (forward_to_next_line_start): Don't use the shortcut if
15407 (back_to_previous_visible_line_start): If handle_display_prop
15408 pushed the iterator stack, restore the internal state of the bidi
15409 iterator by calling bidi_pop_it same number of times.
15410 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
15411 and we are bidi-iterating, don't decrement the iterator position;
15412 instead, set the first_elt flag in the bidi iterator, to produce
15414 (reseat_1): Remove redundant setting of string_from_display_prop_p.
15415 (push_display_prop): xassert that we are iterating a buffer.
15416 (push_it, pop_it): Save and restore paragraph_embedding member.
15417 (handle_single_display_spec, next_overlay_string)
15418 (get_overlay_strings_1, reseat_1, reseat_to_string)
15419 (push_display_prop): Set up the `unibyte' member of bidi_it.string
15420 correctly. Don't assume unibyte strings are not bidi-reordered.

15428 popping after iteration over a string that came from a display
15429 property. Fix a typo in popping stretch info. Add an assertion
15430 for verifying that the iterator position is in sync with the bidi
15432 (handle_single_display_spec, get_overlay_strings_1)

15446 (try_scrolling, redisplay_window, display_line): Use them when
15447 saving a temporary copy of the iterator and restoring it back.

15486 changed to -1 and -2, respectively.
15487 (bidi_char_at_pos): New function.
15488 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):

15521 (bidi_push_it, bidi_pop_it): Add prototypes.
15522 (struct iterator_stack_entry): New members bidi_p,
15523 paragraph_embedding, and from_disp_prop_p.

15571 Pass Qx_lost_selection_functions rather than
15572 Vx_lost_selection_functions to Frun_hook_with_args.
15574 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
15576 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
15577 The old code sometimes used this field without initializing it.
15579 * alloc.c (gc_sweep): Don't read past end of array.
15580 In theory, the old code could also have corrupted Emacs internals,
15581 though it'd be very unlikely.

15585 * character.c (Fcharacterp): Don't advertise optional ignored
15586 argument. (Bug#4026)

15844 (clone_per_buffer_values): Don't assume that

15846 This isn't true in general, and it's particularly not true
15847 if Emacs is configured with --with-wide-int.
15848 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
15849 New macros, used in the buffer.c change.

15885 Random fixes. E.g., (random) never returned negative values.
15886 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
15887 subseconds part to the entropy, as that's a bit more random.
15888 Prefer signed to unsigned, since the signedness doesn't matter and
15889 in general we prefer signed. When given a limit, use a
15890 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
15891 latter isn't right if USE_2_TAGS_FOR_INTS.
15892 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
15893 not 0..VALMASK. Don't discard "excess" bits that random () returns.
15895 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
15897 * textprop.c (text_property_stickiness):
15898 Obey Vtext_property_default_nonsticky.

15903 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
15905 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
15906 This is more efficient than Ffile_directory_p and avoids a minor race.
15908 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
15910 * buffer.c (Foverlay_put): Say what the return value is
15913 * fileio.c (barf_or_query_if_file_exists): Check first if the file
15914 is a directory before asking whether to use the file name
15916 (barf_or_query_if_file_exists): Make the "File is a directory"
15917 error be more correct.
15919 * fns.c (Frequire): Remove the mention of the .gz files, since
15920 that's installation-specific, but keep the mention of
15921 `get-load-suffixes'.
15923 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
15925 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

15931 (syms_of_gnutls): Remove duplicate DEFSYM for
15932 Qgnutls_bootprop_verify_hostname_error, an error for
15933 Qgnutls_bootprop_verify_error (which is no longer used).
15935 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
15936 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
15937 Also (re)move comments that are misplaced or no longer relevant.

15959 2011-07-02 Chong Yidong <cyd@stupidchicken.com>
15961 * keyboard.c (command_loop_1): If a down-mouse event is unbound,
15962 leave any prefix arg for the up event (Bug#1586).
15964 2011-07-02 Lars Magne Ingebrigtsen <larsi@gnus.org>
15966 * lread.c (syms_of_lread): Mention single symbols defined by
15967 `defvar' or `defconst' (bug#7154).
15969 * fns.c (Frequire): Mention .el.gz files (bug#7314).
15970 (Frequire): Mention get-load-suffixes.

16000 (syms_of_keymap): Defsubr make-composed-keymap.
16001 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

16030 (xgselect_initialize): Ditto.
16032 * process.c: Add defined (HAVE_GSETTINGS) for xgselect.h

16038 * eval.c (struct backtrace): Simplify and port the data structure.
16039 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
16040 signed bit field, as this assumption is not portable and it makes
16041 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
16042 "char debug_on_exit : 1" as this is not portable either; instead,
16043 use the portable "unsigned int debug_on_exit : 1". Remove unused
16044 member evalargs. Remove obsolete comments about cc bombing out.
16046 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

16140 Use gnulib's dup2 module instead of rolling our own.
16141 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.
16143 2011-06-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16145 * dispnew.c (scrolling_window): Before scrolling, turn off a

16212 * print.c (printchar, strout): Check for string overflow.
16213 (PRINTPREPARE, printchar, strout):
16214 Don't set size unless allocation succeeds.
16216 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
16217 for sizes. Check for string overflow more accurately.
16218 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
16220 * macros.c: Integer and buffer overflow fixes.
16221 * keyboard.h (struct keyboard.kbd_macro_bufsize):
16222 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

16226 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
16228 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
16230 * lread.c: Integer overflow fixes.
16231 (read_integer): Radix is now EMACS_INT, not int,
16232 to improve quality of diagnostics for out-of-range radices.
16233 Calculate buffer size correctly for out-of-range radices.
16234 (read1): Check for integer overflow in radices, and in
16235 read-circle numbers.
16236 (read_escape): Avoid int overflow.
16237 (Fload, openp, read_buffer_size, read1)
16238 (substitute_object_recurse, read_vector, read_list, map_obarray):
16239 Use ptrdiff_t, not int, for sizes.

16254 2011-06-22 Leo Liu <sdl.web@gmail.com>
16256 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
16257 Move to minibuffer.el.
16259 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
16261 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
16262 The following patches are for when GLYPH_DEBUG && !XASSERT.
16263 * dispextern.h (trace_redisplay_p, dump_glyph_string):
16264 * dispnew.c (flush_stdout):
16265 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
16266 Mark as externally visible.
16267 * dispnew.c (check_window_matrix_pointers): Now static.
16268 * dispnew.c (window_to_frame_vpos):
16269 * xfns.c (unwind_create_frame):
16270 * xterm.c (x_check_font): Remove unused local.
16271 * scroll.c (CHECK_BOUNDS):
16272 * xfaces.c (cache_fache): Rename local to avoid shadowing.
16273 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
16274 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
16275 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
16276 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
16278 (debug_method_add): Use va_list and vsprintf rather than relying
16279 on undefined behavior with wrong number of arguments.
16280 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
16281 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
16282 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
16283 since we're not interested in debugging glyphs with old libraries.
16284 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
16285 GCC 4.6.0's static checking.
16287 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
16289 Integer overflow and signedness fixes (Bug#8873).

16305 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
16306 (.bitmaps_last, struct x_output.icon_bitmap):
16307 Use ptrdiff_t, not int, for bitmap indexes.
16308 (x_allocate_bitmap_record): Check for size overflow.
16309 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
16311 Use ptrdiff_t, not int, for overlay counts.
16312 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
16313 * editfns.c (overlays_around, get_pos_property):
16314 * textprop.c (get_char_property_and_overlay):
16315 * xdisp.c (next_overlay_change, note_mouse_highlight):
16316 * xfaces.c (face_at_buffer_position):
16317 * buffer.c (OVERLAY_COUNT_MAX): New macro.
16318 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
16319 (Fnext_overlay_change, Fprevious_overlay_change)
16320 (mouse_face_overlay_overlaps, Foverlays_in):
16321 Use ptrdiff_t, not int, for sizes.
16322 (overlays_at, overlays_in): Check for size-calculation overflow.
16324 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
16326 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
16327 (x_session_initialize): Do not assume string length fits in int.
16329 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
16330 This is unlikely, but can occur if DPI is outlandish.
16332 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
16333 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
16335 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
16336 * xrdb.c (magic_file_p, search_magic_path):
16337 Omit last arg SUFFIX; it was always 0. All callers changed.
16338 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
16340 * xfont.c (xfont_match): Avoid need for strlen.
16342 * xfns.c: Don't assume strlen fits in int.

16345 * xdisp.c (message_log_check_duplicate): Return intmax_t,
16346 not unsigned long, as we prefer signed integers. All callers changed.
16347 Detect integer overflow in repeat count.
16348 (message_dolog): Don't assume print length fits in 39 bytes.
16349 (display_mode_element): Don't assume strlen fits in int.
16351 * termcap.c: Don't assume sizes fit in int and never overflow.
16352 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
16353 (gobble_line): Check for size-calculation overflow.
16355 * minibuf.c (Fread_buffer):
16356 * lread.c (intern, intern_c_string):
16357 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

16370 * filelock.c: Fix some buffer overrun and integer overflow issues.
16371 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
16372 Reformulate so as not to need the command string.
16373 Invoke gzip -cd rather than gunzip, as it's more portable.
16374 (lock_info_type, lock_file_1, lock_file):
16375 Don't assume pid_t and time_t fit in unsigned long.
16376 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
16377 (current_lock_owner): Prefer signed type for sizes.
16378 Use memcpy, not strncpy, where memcpy is what is really wanted.
16379 Don't assume (via atoi) that time_t and pid_t fit in int.
16380 Check for time_t and/or pid_t out of range, e.g., via a network share.
16381 Don't alloca where an auto var works fine.
16383 * fileio.c: Fix some integer overflow issues.
16384 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
16385 Don't assume string length fits in int.
16386 (directory_file_name): Don't assume string length fits in long.
16387 (make_temp_name): Don't assume pid fits in int, or that its print
16388 length is less than 20.
16390 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
16392 * coding.c (make_subsidiaries): Don't assume string length fits in int.
16394 * callproc.c (child_setup): Rewrite to avoid two strlen calls.

16407 (Fgetenv_internal):
16408 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
16410 * lread.c (invalid_syntax): Omit length argument.
16411 All uses changed. This doesn't fix a bug, but it simplifies the
16412 code away from its former Hollerith-constant appearance, and it's
16413 one less 'int' to worry about when looking at integer-overflow issues.
16414 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
16416 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
16417 This didn't break anything, but it didn't help either.
16418 It's confusing to put a bogus integer in a place where the actual
16419 value does not matter.
16420 (LIST_END_P): Remove unused macro and its bogus comment.
16421 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
16423 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
16424 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
16426 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
16427 We prefer signed types, and the value cannot exceed the EMACS_INT
16428 range anyway (because otherwise the length would not be representable).
16429 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
16430 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
16431 This avoids a GCC warning when WIDE_EMACS_INT.
16433 * indent.c (sane_tab_width): New function.
16434 (current_column, scan_for_column, Findent_to, position_indentation)
16435 (compute_motion): Use it. This is just for clarity.
16436 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
16438 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
16440 * lisp.h (lint_assume): New macro.
16441 * composite.c (composition_gstring_put_cache):
16442 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
16444 * editfns.c, insdel.c:
16445 Omit unnecessary forward decls, to simplify future changes.
16447 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
16449 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
16451 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
16452 Use much-faster test for byte-length change.
16453 Don't assume string byte-length fits in 'int'.
16454 Check that character arg fits in 'int'.
16455 (mapcar1): Declare byte as byte, for clarity.
16457 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
16459 * fns.c (concat): Catch string overflow earlier.
16460 Do not rely on integer wraparound.
16462 * dispextern.h (struct it.overlay_strings_charpos)
16463 (struct it.selective): Now EMACS_INT, not int.
16464 * xdisp.c (forward_to_next_line_start)
16465 (back_to_previous_visible_line_start)
16466 (reseat_at_next_visible_line_start, next_element_from_buffer):
16467 Don't arbitrarily truncate the value of 'selective' to int.
16469 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
16471 * composite.c: Don't truncate sizes to 'int'.
16472 (composition_gstring_p, composition_reseat_it)
16473 (composition_adjust_point): Use EMACS_INT, not int.
16474 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
16475 not EMACS_UINT, for indexes.
16477 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
16479 * buffer.c: Include <verify.h>.
16480 (struct sortvec.priority, struct sortstr.priority):
16481 Now EMACS_INT, not int.
16482 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
16483 (struct sortstr.size, record_overlay_string)
16484 (struct sortstrlist.size, struct sortlist.used):
16485 Don't truncate size to int.
16486 (record_overlay_string): Check for size-calculation overflow.
16487 (init_buffer_once): Check at compile-time, not run-time.
16489 2011-06-22 Jim Meyering <meyering@redhat.com>
16491 Don't leak an XBM-image-sized buffer
16492 * image.c (xbm_load): Free the image buffer after using it.
16494 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
16497 * composite.c (find_automatic_composition): Omit needless 'return 0;'
16498 that Sun C diagnosed.
16499 * fns.c (secure_hash): Fix pointer signedness issue.
16500 * intervals.c (static_offset_intervals): New function.
16501 (offset_intervals): Use it.
16503 2011-06-21 Leo Liu <sdl.web@gmail.com>
16506 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
16509 * fns.c (secure_hash): Rename from crypto_hash_function and change
16510 the first arg to accept symbols.
16511 (Fsecure_hash): New primitive.
16512 (syms_of_fns): New symbols.
16514 2011-06-20 Deniz Dogan <deniz@dogan.se>
16516 * process.c (Fset_process_buffer): Clarify return value in
16519 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
16521 * dispnew.c (add_window_display_history): Use BVAR.
16523 * xdisp.c (debug_method_add): Use BVAR.
16524 (check_window_end, dump_glyph_matrix, dump_glyph)
16525 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
16527 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
16530 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
16531 check till after the cache is created in init_frame_faces.
16533 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
16535 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
16537 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
16539 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
16540 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
16541 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
16543 Improve buffer-overflow checking (Bug#8873).
16544 * fileio.c (Finsert_file_contents):
16545 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
16546 Remove the old (too-loose) buffer overflow checks.
16547 They weren't needed, since make_gap checks for buffer overflow.
16548 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
16549 The old code merely checked for Emacs fixnum overflow, and relied
16550 on undefined (wraparound) behavior. The new code avoids undefined
16551 behavior, and also checks for ptrdiff_t and/or size_t overflow.
16553 * editfns.c (Finsert_char): Don't dump core with very negative counts.
16554 Tune. Don't use wider integers than needed. Don't use alloca.
16555 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
16557 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
16559 * insdel.c, lisp.h (buffer_overflow): New function.
16560 (insert_from_buffer_1, replace_range, replace_range_2):
16561 * insdel.c (make_gap_larger):
16562 * editfns.c (Finsert_char):
16563 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
16565 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
16567 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
16569 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
16571 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
16572 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
16574 * fileio.c: Don't assume EMACS_INT fits in off_t.
16575 (emacs_lseek): New static function.
16576 (Finsert_file_contents, Fwrite_region): Use it.
16577 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
16579 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
16581 * fns.c: Don't overflow int when computing a list length.
16582 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
16583 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
16584 truncation on 64-bit hosts. Check for QUIT every
16585 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
16586 faster and is responsive enough.
16587 (Flength): Report an error instead of overflowing an integer.
16588 (Fsafe_length): Return a float if the value is not representable
16589 as a fixnum. This shouldn't happen except in contrived situations.
16590 (Fnthcdr, Fsort): Don't assume list length fits in int.
16591 (Fcopy_sequence): Don't assume vector length fits in int.
16593 * alloc.c: Check that resized vectors' lengths fit in fixnums.
16594 (header_size, word_size): New constants.
16595 (allocate_vectorlike): Don't check size overflow here.
16596 (allocate_vector): Check it here instead, since this is the only
16597 caller of allocate_vectorlike that could cause overflow.
16598 Check that the new vector's length is representable as a fixnum.
16600 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
16601 The previous code was bogus. For example, next_almost_prime (32)
16602 returned 39, which is undesirable as it is a multiple of 3; and
16603 next_almost_prime (24) returned 25, which is a multiple of 5 so
16604 why was the code bothering to check for multiples of 7?
16606 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
16608 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
16610 Variadic C functions now count arguments with ptrdiff_t.
16611 This partly undoes my 2011-03-30 change, which replaced int with size_t.
16612 Back then I didn't know that the Emacs coding style prefers signed int.
16613 Also, in the meantime I found a few more instances where arguments
16614 were being counted with int, which may truncate counts on 64-bit
16615 machines, or EMACS_INT, which may be unnecessarily wide.
16616 * lisp.h (struct Lisp_Subr.function.aMANY)
16617 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
16618 Arg counts are now ptrdiff_t, not size_t.
16619 All variadic functions and their callers changed accordingly.
16620 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
16621 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
16622 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
16623 * callint.c (Fcall_interactively): Check arg count for overflow,
16624 to avoid potential buffer overrun. Use signed char, not 'int',
16625 for 'varies' array, so that we needn't bother to check its size
16626 calculation for overflow.
16627 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
16628 * eval.c (apply_lambda):
16629 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
16630 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
16631 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
16633 * callint.c (Fcall_interactively): Don't use index var as event count.
16635 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
16636 * mem-limits.h (SIZE): Remove; no longer used.
16638 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
16640 Remove unnecessary casts.
16641 * xterm.c (x_term_init):
16642 * xfns.c (x_set_border_pixel):
16643 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
16644 These aren't needed now that we assume ANSI C.
16646 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
16647 It's more likely to cause problems (due to unsigned overflow)
16650 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
16652 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
16654 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
16656 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
16658 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
16660 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
16662 GLYPH_CODE_FACE returns EMACS_INT, not int.
16663 * dispextern.h (merge_faces):
16664 * xfaces.c (merge_faces):
16665 * xdisp.c (get_next_display_element, next_element_from_display_vector):
16666 Don't assume EMACS_INT fits in int.
16668 * character.h (CHAR_VALID_P): Remove unused parameter.
16669 * fontset.c, lisp.h, xdisp.c: All uses changed.
16671 * editfns.c (Ftranslate_region_internal): Omit redundant test.
16673 * fns.c (concat): Minor tuning based on overflow analysis.
16674 This doesn't fix any bugs. Use int to hold character, instead
16675 of constantly refetching from Emacs object. Use XFASTINT, not
16676 XINT, for value known to be a character. Don't bother comparing
16677 a single byte to 0400, as it's always less.
16679 * floatfns.c (Fexpt):
16680 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
16682 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
16685 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
16687 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
16688 Without this fix, on a 64-bit host (aset S 0 4294967386) would
16689 incorrectly succeed when S was a string, because 4294967386 was
16690 truncated before it was used.
16692 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
16693 Otherwise, an out-of-range integer could cause undefined behavior
16696 * composite.c: Use int, not EMACS_INT, for characters.
16697 (fill_gstring_body, composition_compute_stop_pos): Use int, not
16698 EMACS_INT, for values that are known to be in character range.
16699 This doesn't fix any bugs but is the usual style inside Emacs and
16700 may generate better code on 32-bit machines.
16702 Make sure a 64-bit char is never passed to ENCODE_CHAR.
16703 This is for reasons similar to the recent CHAR_STRING fix.
16704 * charset.c (Fencode_char): Check that character arg is actually
16705 a character. Pass an int to ENCODE_CHAR.
16706 * charset.h (ENCODE_CHAR): Verify that the character argument is no
16707 wider than 'int', as a compile-time check to prevent future regressions
16710 * character.c (char_string): Remove unnecessary casts.
16712 Make sure a 64-bit char is never passed to CHAR_STRING.
16713 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
16714 by silently ignoring the top 32 bits, allowing some values
16715 that were far too large to be valid characters.
16716 * character.h: Include <verify.h>.
16717 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
16718 arguments are no wider than unsigned, as a compile-time check
16719 to prevent future regressions in this area.
16721 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
16722 (Fsubst_char_in_region):
16724 * xdisp.c (decode_mode_spec_coding):
16725 Adjust to CHAR_STRING's new requirement.
16726 * editfns.c (Finsert_char, Fsubst_char_in_region):
16727 * fns.c (concat): Check that character args are actually
16728 characters. Without this test, these functions did the wrong
16729 thing with wildly out-of-range values on 64-bit hosts.
16731 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
16732 These casts should not be needed on 32-bit hosts, either.
16733 * keyboard.c (read_char):
16734 * lread.c (Fload): Remove casts to unsigned.
16736 * lisp.h (UNSIGNED_CMP): New macro.
16737 This fixes comparison bugs on 64-bit hosts.
16738 (ASCII_CHAR_P): Use it.
16739 * casefiddle.c (casify_object):
16740 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
16741 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
16742 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
16743 * dispextern.h (FACE_FROM_ID):
16744 * keyboard.c (read_char): Use UNSIGNED_CMP.
16746 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
16747 not to EMACS_INT, to avoid GCC warning.
16749 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
16751 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
16752 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
16753 isn't needed on 32-bit machines.
16755 * buffer.c (Fgenerate_new_buffer_name):
16756 Use EMACS_INT for count, not int.
16757 (advance_to_char_boundary): Return EMACS_INT, not int.
16759 * data.c (Qcompiled_function): Now static.
16761 * window.c (window_body_lines): Now static.
16763 * image.c (gif_load): Rename local to avoid shadowing.
16765 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
16766 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
16767 * alloc.c (make_save_value): Integer argument is now of type
16768 ptrdiff_t, not int.
16769 (mark_object): Use ptrdiff_t, not int.
16770 * lisp.h (pD): New macro.
16771 * print.c (print_object): Use it.
16773 * alloc.c: Use EMACS_INT, not int, to count objects.
16774 (total_conses, total_markers, total_symbols, total_vector_size)
16775 (total_free_conses, total_free_markers, total_free_symbols)
16776 (total_free_floats, total_floats, total_free_intervals)
16777 (total_intervals, total_strings, total_free_strings):
16778 Now EMACS_INT, not int. All uses changed.
16779 (Fgarbage_collect): Compute overall total using a double, so that
16780 integer overflow is less likely to be a problem. Check for overflow
16781 when converting back to an integer.
16782 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
16783 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
16784 These were 'int' variables that could overflow on 64-bit hosts;
16785 they were never used, so remove them instead of repairing them.
16786 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
16787 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
16788 Previously, this ceilinged at INT_MAX, but that doesn't work on
16790 (allocate_pseudovector): Don't use EMACS_INT when int would do.
16792 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
16793 (allocate_vectorlike): Check for ptrdiff_t overflow.
16794 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
16795 when a (possibly-narrower) signed value would do just as well.
16796 We prefer using signed arithmetic, to avoid comparison confusion.
16798 * alloc.c: Catch some string size overflows that we were missing.
16799 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
16800 for convenience in STRING_BYTES_MAX.
16801 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
16802 The definition here is exact; the one in lisp.h was approximate.
16803 (allocate_string_data): Check for string overflow. This catches
16804 some instances we weren't catching before. Also, it catches
16805 size_t overflow on (unusual) hosts where SIZE_MAX <= min
16806 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
16807 and ptrdiff_t and EMACS_INT are both 64 bits.
16809 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
16810 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
16811 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
16813 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
16815 * alloc.c (Fmake_string): Check for out-of-range init.
16817 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
16819 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
16821 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
16823 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
16824 xg_get_default_scrollbar_width.
16826 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
16827 (int_gtk_range_get_value): Move to the scroll bar part of the file.
16828 (style_changed_cb): Call update_theme_scrollbar_width and call
16829 x_set_scroll_bar_default_width and xg_frame_set_char_size for
16830 all frames (Bug#8505).
16831 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
16832 Call gtk_window_set_resizable if HAVE_GTK3.
16833 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
16834 and height if HAVE_GTK3 (Bug#8505).
16835 (scroll_bar_width_for_theme): New variable.
16836 (update_theme_scrollbar_width): New function.
16837 (xg_get_default_scrollbar_width): Move code to
16838 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
16839 (xg_initialize): Call update_theme_scrollbar_width.
16841 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
16843 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
16845 2011-06-12 Martin Rudalics <rudalics@gmx.at>
16847 * frame.c (make_frame): Call other_buffer_safely instead of
16850 * window.c (temp_output_buffer_show): Call display_buffer with
16851 second argument Vtemp_buffer_show_specifiers and reset latter
16852 immediately after the call.
16853 (Vtemp_buffer_show_specifiers): New variable.
16854 (auto_window_vscroll_p, next_screen_context_lines)
16855 (Vscroll_preserve_screen_position): Remove leading asterisks from
16858 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
16860 Fix minor problems found by GCC 4.6.0 static checking.
16861 * buffer.c (Qclone_number): Remove for now, as it's unused.
16862 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
16863 (record_buffer): Remove unused local.
16864 * frame.c (other_visible_frames, frame_buffer_list): Now static.
16865 (set_frame_buffer_list): Remove; unused.
16866 * frame.h (other_visible_frames): Remove decl.
16867 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
16868 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
16869 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
16871 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
16872 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
16873 Define only if HAVE_GPM.
16874 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
16875 (update_hints_inhibit): Remove; never set. All uses removed.
16876 * widgetprv.h (emacsFrameClassRec): Remove decl.
16877 * window.c (delete_deletable_window): Now returns void, since it
16878 wasn't returning anything.
16879 (compare_window_configurations): Remove unused locals.
16880 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
16881 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
16882 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
16883 the same widths as pointers. This follows up on the 2011-05-06 patch.
16884 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
16885 * xterm.h: Likewise.
16886 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
16888 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
16890 * makefile.w32-in: Update dependencies.
16891 (LISP_H): Add lib/intprops.h.
16893 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
16895 * image.c (gif_load): Add animation frame delay to the metadata.
16896 (syms_of_image): Use DEFSYM. New symbol `delay'.
16898 2011-06-11 Martin Rudalics <rudalics@gmx.at>
16900 * window.c (delete_deletable_window): Re-add.
16901 (Fset_window_configuration): Rewrite to handle dead buffers and
16902 consequently deletable windows.
16903 (window_tree, Fwindow_tree): Remove. Supply functionality in
16905 (compare_window_configurations): Simplify code.
16907 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
16909 * image.c (imagemagick_load_image): Fix type mismatch.
16910 (Fimagemagick_types): Likewise.
16912 * window.h (replace_buffer_in_windows): Declare.
16914 2011-06-11 Martin Rudalics <rudalics@gmx.at>
16916 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
16917 Qclone_number. Remove external declaration of Qdelete_window.
16918 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
16920 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
16921 Run Qbuffer_list_update_hook if allowed.
16922 (Fother_buffer): Rewrite doc-string. Major rewrite for new
16923 buffer list implementation.
16924 (other_buffer_safely): New function.
16925 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
16926 calls to replace_buffer_in_windows and
16927 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
16929 (record_buffer): Inhibit quitting and rewrite using quittable
16930 functions. Run Qbuffer_list_update_hook if allowed.
16931 (Frecord_buffer, Funrecord_buffer): New functions.
16932 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
16933 Move switch-to-buffer to window.el.
16934 (bury-buffer): Move to window.el.
16935 (Vbuffer_list_update_hook): New variable.
16937 * lisp.h (other_buffer_safely): Add prototype in buffer.c
16940 * window.h (resize_frame_windows): Move up in code.
16941 (Fwindow_frame): Remove EXFUN.

17391 bidirectional text is supported only in multibyte buffers.
17392 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
17393 it to initialize the frame_window_p member of struct bidi_it.
17394 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
17395 (bidi_resolve_explicit, bidi_resolve_weak)
17396 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
17397 bidi_it->nchars is non-positive.
17398 (bidi_level_of_next_char): Don't try to lookup the cache for the
17399 next/previous character if nothing is cached there yet, or if we
17400 were just reseat()'ed to a new position.
17402 * xdisp.c (set_cursor_from_row): Set start and stop points
17403 according to the row's direction when priming the loop that looks
17404 for the glyph on which to display cursor.
17405 (single_display_spec_intangible_p): Function deleted.
17406 (display_prop_intangible_p): Reimplement to call
17407 handle_display_spec instead of single_display_spec_intangible_p.
17408 Accept 3 additional arguments needed by handle_display_spec.
17409 This fixes incorrect cursor motion across display property with complex
17410 values: lists, `(when COND...)' forms, etc.
17411 (single_display_spec_string_p): Support property values that are
17412 lists with the argument STRING its top-level element.
17413 (display_prop_string_p): Fix the condition for processing a
17414 property that is a list to be consistent with handle_display_spec.
17415 (handle_display_spec): New function, refactored from the
17416 last portion of handle_display_prop.
17417 (compute_display_string_pos): Accept additional argument
17418 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
17419 value of a `display' property is a "replacing spec".
17420 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
17421 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
17422 the display property, but just return a value indicating whether
17423 the display property will replace the characters it covers.
17424 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
17425 frame_window_p members of struct bidi_it.
17426 (compute_display_string_pos, compute_display_string_end):
17428 (push_it): Accept second argument POSITION, where pop_it should
17429 jump to continue iteration.
17430 (reseat_1): Initialize bidi_it.disp_pos.
17432 * keyboard.c (adjust_point_for_property): Adjust the call to
17433 display_prop_intangible_p to its new signature.
17435 * dispextern.h (struct bidi_it): New member frame_window_p.
17436 (bidi_init_it): Update prototypes.
17437 (display_prop_intangible_p): Update prototype.
17438 (compute_display_string_pos, compute_display_string_end):
17439 Declare prototypes.
17440 (struct bidi_it): New members nchars and disp_pos. ch_len is now
17443 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
17445 Malloc failure behavior now depends on size of allocation.
17446 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
17447 * lisp.h: Change signatures accordingly.
17448 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
17449 All callers changed. (Bug#8762)
17451 * gnutls.c: Use Emacs's memory allocators.
17452 Without this change, the gnutls library would invoke malloc etc.
17453 directly, which causes problems on non-SYNC_INPUT hosts, and which
17454 runs afoul of improving memory_full behavior. (Bug#8761)
17455 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
17456 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
17457 xfree instead of the default malloc, realloc, free.
17458 (Fgnutls_boot): No need to check for memory allocation failure,
17459 since xmalloc does that for us.
17461 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
17462 * category.c (hash_get_category_set):
17463 * ccl.c (ccl_driver):

17475 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
17476 (Fsxhash, Fgethash, Fputhash, Fmaphash):
17477 * image.c (make_image, search_image_cache, lookup_image)
17478 (xpm_put_color_table_h):
17479 * lisp.h (struct Lisp_Hash_Table):
17480 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
17481 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
17482 for hashes and hash indexes, instead of 'unsigned' and 'int'.
17483 * alloc.c (allocate_vectorlike):
17484 Check for overflow in vector size calculations.
17485 * ccl.c (ccl_driver):
17486 Check for overflow when converting EMACS_INT to int.
17487 * fns.c, image.c: Remove unnecessary static decls that would otherwise
17488 need to be updated by these changes.
17489 * fns.c (make_hash_table, maybe_resize_hash_table):
17490 Check for integer overflow with large hash tables.
17491 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
17492 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
17493 (SXHASH_REDUCE): New macro.
17494 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
17495 Use it instead of discarding useful hash info with large hash values.
17496 (sxhash_float): New function.
17497 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
17498 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
17499 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
17500 Rewrite to use FIXNUM_BITS, as this simplifies things.
17501 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
17502 Adjust signatures to match updated version of code.
17503 (consing_since_gc): Now EMACS_INT, since a single hash table can
17504 use more than INT_MAX bytes.
17506 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
17508 Make it possible to build with GCC-4.6+ -O2 -flto.
17510 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
17512 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
17514 * minibuf.c (get_minibuffer, read_minibuf_unwind):
17515 Call minibuffer-inactive-mode.
17517 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
17519 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
17520 Update dependencies.
17522 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17524 * data.c (init_data): Remove code for UTS, this system is not
17527 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17529 Don't force ./temacs to start in terminal mode.
17531 * frame.c (make_initial_frame): Initialize faces in all cases, not
17532 only when CANNOT_DUMP is defined.
17533 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
17535 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17537 * dispnew.c (add_window_display_history): Use const for the string
17538 pointer. Remove declaration, not needed.
17540 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
17542 Use 'inline', not 'INLINE'.
17543 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
17544 * alloc.c, fontset.c (INLINE): Remove.
17545 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
17546 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
17547 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
17548 * gmalloc.c (register_heapinfo): Use inline unconditionally.
17549 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
17551 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17553 Make it possible to run ./temacs.
17555 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
17556 syms_of_callproc does the same thing. Remove test for
17557 "initialized", do it in the caller.
17558 * emacs.c (main): Avoid calling set_initial_environment when dumping.
17560 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
17562 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
17563 (read_minibuf): Use get_minibuffer.
17564 (syms_of_minibuf): Use DEFSYM.
17565 (Qmetadata): New var.
17566 * data.c (Qbuffer): Don't make it static.
17567 (syms_of_data): Use DEFSYM.
17569 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
17571 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
17572 (CCL_CODE_MIN): New macro.
17574 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
17576 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
17578 * eval.c (Qdebug): Now static.
17579 * lisp.h (Qdebug): Remove decl. This reverts a part of the
17580 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
17581 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
17583 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
17585 * image.c: Various fixes to ImageMagick code comments.
17586 (Fimagemagick_types): Doc fix.
17588 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
17590 Minor fixes prompted by GCC 4.6.0 warnings.
17592 * xselect.c (converted_selections, conversion_fail_tag): Now static.
17594 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
17595 (x_clipboard_manager_save_all): Move extern decl to ...
17596 * xterm.h: ... here, so that it can be checked for consistency.
17598 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
17600 * xselect.c (x_clipboard_manager_save_frame)
17601 (x_clipboard_manager_save_all): New functions.
17602 (Fx_clipboard_manager_save): Lisp function deleted.
17604 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
17605 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
17607 * xterm.h: Update prototype.
17609 2011-05-28 William Xu <william.xwl@gmail.com>
17611 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
17612 exiting (Bug#8239).
17614 2011-05-28 Jim Meyering <meyering@redhat.com>
17616 Avoid a sign-extension bug in crypto_hash_function.
17617 * fns.c (to_uchar): Define.
17618 (crypto_hash_function): Use it to convert some newly-signed
17619 variables to unsigned, to avoid sign-extension bugs. For example,
17620 without this change, (md5 "truc") would evaluate to
17621 45723a2aff78ff4fff7fff1114760e62 rather than the expected
17622 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
17623 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
17625 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17627 Integer overflow fixes.
17629 * dbusbind.c: Serial number integer overflow fixes.
17630 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
17631 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
17632 to hold a serial number that is too large for a fixnum.
17633 (Fdbus_method_return_internal, Fdbus_method_error_internal):
17634 Check for serial numbers out of range. Decode any serial number
17635 that was so large that it became a float. (Bug#8722)
17637 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
17638 (Fdbus_call_method, Fdbus_call_method_asynchronously):
17639 Use XFASTINT rather than XUINT when numbers are nonnegative.
17640 (xd_append_arg, Fdbus_method_return_internal):
17641 (Fdbus_method_error_internal): Likewise. Also, for unsigned
17642 arguments, check that Lisp number is nonnegative, rather than
17643 silently wrapping negative numbers around. (Bug#8722)
17644 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
17647 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
17649 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
17651 ccl: Add integer overflow checks.
17652 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
17653 (IN_INT_RANGE): New macros.
17654 (ccl_driver): Use them to check for integer overflow when
17655 decoding a CCL program. Many of the new checks are whether XINT (x)
17656 fits in int; it doesn't always, on 64-bit hosts. The new version
17657 doesn't catch all possible integer overflows, but it's an
17658 improvement. (Bug#8719)
17660 * alloc.c (make_event_array): Use XINT, not XUINT.
17661 There's no need for unsigned here.
17663 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
17664 This follows up to the 2011-05-06 change that substituted uintptr_t
17665 for EMACS_INT. This case wasn't caught back then.
17667 Rework Fformat to avoid integer overflow issues.
17668 * editfns.c: Include <float.h> unconditionally, as it's everywhere
17669 now (part of C89). Include <verify.h>.
17670 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
17671 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
17672 (Fformat): Avoid the prepass trying to compute sizes; it was only
17673 approximate and thus did not catch overflow reliably. Instead, walk
17674 through the format just once, formatting and computing sizes as we go,
17675 checking for integer overflow at every step, and allocating a larger
17676 buffer as needed. Keep track separately whether the format is
17677 multibyte. Keep only the most-recently calculated precision, rather
17678 than them all. Record whether each argument has been converted to
17679 string. Use EMACS_INT, not int, for byte and char and arg counts.
17680 Support field widths and precisions larger than INT_MAX. Avoid
17681 sprintf's undefined behavior with conversion specifications such as %#d
17682 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
17683 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
17684 formatting out-of-range floating point numbers with int
17685 formats. (Bug#8668)
17687 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
17689 * data.c: Avoid integer truncation in expressions involving floats.
17690 * data.c: Include <intprops.h>.
17691 (arith_driver): When there's an integer overflow in an expression
17692 involving floating point, convert the integers to floating point
17693 so that the resulting value does not suffer from catastrophic
17694 integer truncation. For example, on a 64-bit host (* 4
17695 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
17696 Do not rely on undefined behavior after integer overflow.
17698 merge count_size_as_multibyte, parse_str_to_multibyte
17699 * character.c, character.h (count_size_as_multibyte):
17700 Rename from parse_str_to_multibyte; all uses changed.
17701 Check for integer overflow.
17702 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
17703 since it's now a duplicate of the other. This is more of
17704 a character than a buffer op, so better that it's in character.c.
17705 * fns.c, print.c: Adjust to above changes.
17707 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
17709 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
17711 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17713 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17714 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
17715 (x_clipboard_manager_save): Now static.
17716 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
17718 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17719 (crypto_hash_function): Now static.
17720 Fix pointer signedness problems. Avoid unnecessary initializations.
17722 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
17724 * termhooks.h (Vselection_alist): Make it terminal-local.
17726 * terminal.c (create_terminal): Initialize it.
17728 * xselect.c: Support for clipboard managers.
17729 (Vselection_alist): Move to termhooks.h as terminal-local var.
17730 (LOCAL_SELECTION): New macro.
17731 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
17732 (symbol_to_x_atom): Remove gratuitous arg.
17733 (x_handle_selection_request, lisp_data_to_selection_data)
17734 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
17735 (x_own_selection, x_get_local_selection, x_convert_selection):
17736 New arg, specifying work frame. Use terminal-local Vselection_alist.
17737 (some_frame_on_display): Delete unused function.
17738 (Fx_own_selection_internal, Fx_get_selection_internal)
17739 (Fx_disown_selection_internal, Fx_selection_owner_p)
17740 (Fx_selection_exists_p): New optional frame arg.
17741 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
17742 (x_handle_selection_clear): Don't treat other terminals with the
17743 same keyboard specially. Use the terminal-local Vselection_alist.
17744 (x_clear_frame_selections): Use Frun_hook_with_args.
17746 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
17748 * xterm.h: Add support for those atoms.
17750 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
17752 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
17753 (converted_selections, conversion_fail_tag): New global variables.
17754 (x_selection_request_lisp_error): Free the above.
17755 (x_get_local_selection): Remove unnecessary code.
17756 (x_reply_selection_request): Args changed; handle arbitrary array
17757 of converted selections stored in converted_selections.
17758 Separate the XChangeProperty and SelectionNotify steps.
17759 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
17760 (x_convert_selection): New function.
17761 (x_handle_selection_event): Simplify.
17762 (x_get_foreign_selection): Don't ignore incoming requests while
17763 waiting for an answer; this will fail when we implement
17764 SAVE_TARGETS, and seems unnecessary anyway.
17765 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
17766 (Vx_sent_selection_functions): Doc fix.
17768 2011-05-26 Leo Liu <sdl.web@gmail.com>
17770 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
17772 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17774 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
17776 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
17777 for fringe update if it has periodic bitmap.
17778 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
17779 and fringe_bitmap_periodic_p.
17781 * fringe.c (get_fringe_bitmap_data): New function.
17782 (draw_fringe_bitmap_1, update_window_fringes): Use it.
17783 (update_window_fringes): Record periodicity of fringe bitmap in glyph
17784 row. Mark glyph row for fringe update if periodicity changed.
17786 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
17787 for fringe update unless it has periodic bitmap.
17789 2011-05-25 Kenichi Handa <handa@m17n.org>
17791 * xdisp.c (get_next_display_element): Set correct it->face_id for
17792 a static composition.

17800 (Fmd5): Use crypto_hash_function.
17801 (syms_of_fns): Add Ssha1.
17803 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
17805 * gnutls.c: Remove unused macros.
17806 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
17807 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
17808 Remove macros that are defined and never used.
17809 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
17811 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17813 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
17814 (Fx_get_selection_internal): Minor cleanup.
17815 (Fx_own_selection_internal): Rename arguments for consistency with
17818 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
17820 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
17822 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17824 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
17826 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17828 * dispnew.c (scrolling_window): Don't exclude the case that the
17829 last enabled row in the desired matrix touches the bottom boundary.
17831 2011-05-21 Glenn Morris <rgm@gnu.org>
17833 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
17834 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
17835 and add some more files.
17837 2011-05-20 Eli Zaretskii <eliz@gnu.org>
17839 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
17840 report_file_error introduced by the change from 2011-05-07.
17842 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
17844 * systime.h (Time): Define only if emacs is defined.
17845 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
17846 where the include path doesn't have X11/X.h by default. See
17847 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
17849 2011-05-20 Kenichi Handa <handa@m17n.org>
17851 * composite.c (find_automatic_composition): Fix previous change.
17853 2011-05-20 Glenn Morris <rgm@gnu.org>
17855 * lisp.mk: New file, split from Makefile.in.
17856 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
17857 (shortlisp): Remove.
17858 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
17860 2011-05-19 Glenn Morris <rgm@gnu.org>
17862 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
17863 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
17864 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
17865 (lisp): Set the order to that of loadup.el.
17866 (shortlisp): Make it a copy of $lisp.
17867 (SOME_MACHINE_LISP): Remove.
17868 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
17869 Use just $shortlisp, not $SOME_MACHINE_LISP too.
17871 2011-05-18 Kenichi Handa <handa@m17n.org>
17873 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
17874 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
17875 (find_automatic_composition): Mostly rewrite for efficiency.
17877 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
17879 * makefile.w32-in: Update dependencies.
17881 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
17883 * menu.c: Include limits.h (fixes the MS-Windows build broken by
17884 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
17886 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
17888 Fix some integer overflow issues, such as string length overflow.
17890 * insdel.c (count_size_as_multibyte): Check for string overflow.
17892 * character.c (lisp_string_width): Check for string overflow.
17893 Use EMACS_INT, not int, for string indexes and lengths; in
17894 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
17895 the resulting string length overflows an EMACS_INT; instead,
17896 report a string overflow if no precision given. When checking for
17897 precision exhaustion, use a check that cannot possibly have
17898 integer overflow. (Bug#8675)
17899 * character.h (lisp_string_width): Adjust to new signature.
17901 * alloc.c (string_overflow): New function.
17902 (Fmake_string): Use it. This doesn't change behavior, but saves
17903 a few bytes and will simplify future changes.
17904 * character.c (string_escape_byte8): Likewise.
17905 * lisp.h (string_overflow): New decl.
17907 Fixups, following up to the user-interface timestamp change.
17908 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
17909 for UI timestamps, instead of unsigned long.
17910 * msdos.c (mouse_get_pos): Likewise.
17911 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
17912 * w32gui.h (Time): Define by including "systime.h" rather than by
17913 declaring it ourselves. (Bug#8664)
17915 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
17916 * image.c (clear_image_cache): Likewise.
17918 * term.c (term_mouse_position): Don't assume time_t wraparound.
17920 Be more systematic about user-interface timestamps.
17921 Before, the code sometimes used 'Time', sometimes 'unsigned long',
17922 and sometimes 'EMACS_UINT', to represent these timestamps.
17923 This change causes it to use 'Time' uniformly, as that's what X uses.
17924 This makes the code easier to follow, and makes it easier to catch
17925 integer overflow bugs such as Bug#8664.
17926 * frame.c (Fmouse_position, Fmouse_pixel_position):
17927 Use Time, not unsigned long, for user-interface timestamps.
17928 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
17929 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
17930 * keyboard.h (last_event_timestamp): Likewise.
17931 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
17932 * menu.h (xmenu_show): Likewise.
17933 * term.c (term_mouse_position): Likewise.
17934 * termhooks.h (struct input_event.timestamp): Likewise.
17935 (struct terminal.mouse_position_hook): Likewise.
17936 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
17937 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
17938 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
17939 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
17940 what it was before.
17941 * menu.h, termhooks.h: Include "systime.h", for Time.
17943 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
17944 Don't assume that the difference between two unsigned long values
17945 can fit into an integer. At this point, we know button_down_time
17946 <= event->timestamp, so the difference must be nonnegative, so
17947 there's no need to cast the result if double-click-time is
17948 nonnegative, as it should be; check that it's nonnegative, just in
17949 case. This bug is triggered when events are more than 2**31 ms
17950 apart (about 25 days). (Bug#8664)
17952 * xselect.c (last_event_timestamp): Remove duplicate decl.
17953 (x_own_selection): Remove needless cast to unsigned long.
17955 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
17956 that always fit in int. Use a sentinel instead of a counter, to
17957 avoid a temp and to allay GCC's concerns about possible int overflow.
17958 * frame.h (struct frame): Use int for menu_bar_items_used
17959 instead of EMACS_INT, since it always fits in int.
17961 * menu.c (grow_menu_items): Check for int overflow.
17963 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
17965 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
17966 Before, the code was not consistent. These values cannot exceed
17967 2**31 - 1 so there's no need to make them unsigned.
17968 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
17969 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
17970 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
17972 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
17974 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
17975 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
17976 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
17977 presumably because the widths might not match.
17979 * window.c (size_window): Avoid needless test at loop start.
17981 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
17983 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
17985 2011-05-12 Drew Adams <drew.adams@oracle.com>
17987 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
17989 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17991 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
17992 `width' to `bar_area_x' and `bar_area_width', respectively.
17993 (x_scroll_run): Take account of fringe background extension.
17995 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
17996 Rename local vars `left' and `width' to `bar_area_x' and
17997 `bar_area_width', respectively.
17998 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
17999 background extension.
18001 2011-05-10 Jim Meyering <meyering@redhat.com>
18003 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
18005 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
18007 * image.c (Finit_image_library): Return t for built-in image types,
18008 like pbm and xbm. (Bug#8640)
18010 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
18012 * w32menu.c (set_frame_menubar): Fix submenu allocation.
18014 2011-05-07 Eli Zaretskii <eliz@gnu.org>
18016 * w32console.c (Fset_screen_color): Doc fix.
18017 (Fget_screen_color): New function.
18018 (syms_of_ntterm): Defsubr it.
18020 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
18021 unlink the temporary file if Fcall_process didn't create it in the
18023 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
18024 child process will be redirected to a file specified with `:file'.
18025 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
18026 cue to call_process_cleanup not to close that handle.
18028 2011-05-07 Ben Key <bkey76@gmail.com>
18030 * makefile.w32-in: The bootstrap-temacs rule now makes use of
18031 one of two shell specific rules, either bootstrap-temacs-CMD or
18032 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
18033 to the previous implementation of the bootstrap-temacs rule.
18034 The bootstrap-temacs-CMD rule is similar to the previous
18035 implementation of the bootstrap-temacs rule except that it
18036 makes use of the ESC_CFLAGS variable instead of the CFLAGS
18039 These changes, along with some changes to nt/configure.bat,
18040 nt/gmake.defs, and nt/nmake.defs, are required to extend my
18041 earlier fix to add support for --cflags and --ldflags options
18042 that include quotes so that it works whether make uses cmd or
18045 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
18047 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
18048 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
18050 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
18051 a string. Handle both cases.
18052 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
18053 (Fdbus_register_method): Use Qinvalid_function.
18055 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18057 * makefile.w32-in: Update dependencies.
18058 (LISP_H): Add inttypes.h and stdin.h.
18059 (PROCESS_H): Add unistd.h.
18061 2011-05-06 Eli Zaretskii <eliz@gnu.org>
18063 * lread.c: Include limits.h (fixes the MS-Windows build broken by
18064 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
18066 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
18068 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
18070 * term.c (vfatal): Remove stray call to va_end.
18071 It's not needed and the C Standard doesn't allow it here anyway.
18073 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
18074 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
18076 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
18079 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
18081 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
18083 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
18085 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
18087 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
18089 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
18090 * charset.c (Fdefine_charset_internal): Don't initialize
18091 charset.code_space[15]. The value was garbage, on hosts with
18092 32-bit int (Bug#8600).
18094 * lread.c (read_integer): Be more consistent with string-to-number.
18095 Use string_to_number to do the actual conversion; this avoids
18096 rounding errors and fixes some other screwups. Without this fix,
18097 for example, #x1fffffffffffffff was misread as -2305843009213693952.
18098 (digit_to_number): Move earlier, for benefit of read_integer.
18099 Return -1 if the digit is out of range for the base, -2 if it is
18100 not a digit in any supported base. (Bug#8602)
18102 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
18104 * dispnew.c (scrolling_window): Return 1 if we scrolled,
18105 to match comment at start of function. This also removes a
18106 GCC warning about overflow in a 32+64-bit port.
18108 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
18110 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
18111 Reported by Stefan Monnier in
18112 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
18113 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18114 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
18116 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
18117 (EMACS_UINTPTR): Likewise, with uintptr_t.
18119 * lisp.h: Prefer 64-bit EMACS_INT if available.
18120 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
18121 on 32-bit hosts that have 64-bit int, so that they can access
18123 However, temporarily disable this change unless the temporary
18124 symbol WIDE_EMACS_INT is defined.
18126 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
18128 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
18129 This removes an assumption that EMACS_INT and long are the same
18130 width as pointers. The assumption is true for Emacs porting targets
18131 now, but we want to make other targets possible.
18132 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
18133 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
18134 In the rest of the code, change types of integers that hold casted
18135 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
18136 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
18137 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
18138 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
18139 No need to cast type when ORing.
18140 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
18141 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
18142 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
18143 assume EMACS_INT is the same width as char *.
18144 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
18145 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
18146 Remove no-longer-needed casts.
18147 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
18148 (xg_tool_bar_help_callback, xg_make_tool_item):
18149 Use EMACS_INTPTR to hold an integer
18150 that will be cast to void *; this can avoid a GCC warning
18151 if EMACS_INT is not the same width as void *.
18152 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
18153 * xdisp.c (display_echo_area_1, resize_mini_window_1):
18154 (current_message_1, set_message_1):
18155 Use a local to convert to proper width without a cast.
18156 * xmenu.c (dialog_selection_callback): Likewise.
18158 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
18159 Also, don't assume VALBITS / RAND_BITS is less than 5,
18160 and don't rely on undefined behavior when shifting a 1 left into
18162 * lisp.h (get_random): Change signature to match.
18164 * lread.c (hash_string): Use size_t, not int, for hash computation.
18165 Normally we prefer signed values; but hashing is special, because
18166 it's better to use unsigned division on hash table sizes so that
18167 the remainder is nonnegative. Also, size_t is the natural width
18168 for hashing into memory. The previous code used 'int', which doesn't
18169 retain enough info to hash well into very large tables.
18170 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
18172 * dbusbind.c: Don't possibly lose pointer info when converting.
18173 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18174 Use XPNTR rather than XHASH, so that the high-order bits of
18175 the pointer aren't lost when converting through void *.
18177 * eval.c (Fautoload): Don't double-shift a pointer.
18179 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
18181 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18183 * gnutls.c (DEF_GNUTLS_FN):
18184 * image.c (DEF_IMGLIB_FN): Make function pointers static.
18186 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
18188 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
18191 2011-05-05 Eli Zaretskii <eliz@gnu.org>
18193 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
18194 New version that can reserve upto 2GB of heap space.
18196 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
18198 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
18200 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
18202 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
18203 `gnutls_certificate_set_x509_key_file'.
18205 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
18207 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
18208 Update dependencies.
18210 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18212 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
18213 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
18214 Remove unused parameter `fildes'.
18215 * process.c (read_process_output, send_process): Don't pass it.
18217 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18219 Fix previous change: the library cache is defined in w32.c.
18220 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
18221 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
18223 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18225 Implement dynamic loading of GnuTLS on Windows.
18227 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
18228 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
18229 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18232 * gnutls.c (Qgnutls_dll): Define.
18233 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
18234 (gnutls_*): Declare function pointers.
18235 (init_gnutls_functions): New function to initialize function pointers.
18236 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
18237 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
18238 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18239 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
18240 (emacs_gnutls_write, emacs_gnutls_read)

18316 rather than `XVECTOR (FOO)->size'.
18318 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
18319 inttypes.h, as a gnulib replacement is used if it not available in

18334 charbuf for the composition carryover bytes.
18336 2011-04-21 Eli Zaretskii <eliz@gnu.org>

18339 aborting when %lld or %lll format is passed.
18340 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
18341 %llo or %llx format is passed. (Bug#8545)
18343 * window.c (window_scroll_line_based): Use a marker instead of
18344 simple variables to record original value of point. (Bug#7952)
18346 * doprnt.c (doprnt): Fix the case where a multibyte sequence
18347 produced by %s or %c overflows available buffer space. (Bug#8545)
18349 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
18351 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
18352 (SIZE_MAX): Move defn after all includes, as they might #define it.
18354 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18356 * w32.c (init_environment): Warn about defaulting HOME to C:\.
18358 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18360 * keyboard.c (Qdelayed_warnings_hook): Define.
18361 (command_loop_1): Run `delayed-warnings-hook'
18362 if Vdelayed_warnings_list is non-nil.
18363 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
18364 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
18366 2011-04-28 Eli Zaretskii <eliz@gnu.org>
18368 * doprnt.c (doprnt): Don't return value smaller than the buffer
18369 size if the message was truncated. (Bug#8545).
18371 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18373 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

18380 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
18382 * makefile.w32-in: Update dependencies.
18384 2011-04-27 Eli Zaretskii <eliz@gnu.org>
18386 Improve `doprnt' and its usage. (Bug#8545)
18387 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
18388 `format_end'. Remove support for %l as a conversion specifier.
18389 Don't use xrealloc. Improve diagnostics when the %l size modifier
18390 is used. Update the commentary.
18392 * eval.c (verror): Simplify calculation of size_t.
18394 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
18397 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
18399 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
18402 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18404 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
18405 This makes this file independent of the recent pseudovector change.
18407 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
18409 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
18411 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
18412 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
18413 Remove unused local.
18414 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
18416 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
18417 GCC 4.6.0 optimizes based on type-based alias analysis.
18418 For example, if b is of type struct buffer * and v of type struct
18419 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
18420 != &v->size, and therefore "v->size = 1; b->size = 2; return
18421 v->size;" must therefore return 1. This assumption is incorrect
18422 for Emacs, since it type-puns struct Lisp_Vector * with many other
18423 types. To fix this problem, this patch adds a new type struct
18424 vectorlike_header that documents the constraints on layout of vectors
18425 and pseudovectors, and helps optimizing compilers not get fooled
18426 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
18427 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
18428 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
18430 (XSETPVECTYPE): Rewrite in terms of new macro.
18431 (XSETPVECTYPESIZE): New macro, specifying both type and size.
18432 This is a bit clearer, and further avoids the possibility of
18433 undesirable aliasing.
18434 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
18435 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
18436 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
18437 since Lisp_Subr is a special case (no "next" field).
18438 (ASIZE): Now uses header.size rather than size.
18439 All previous uses of XVECTOR (foo)->size replaced to use this macro,
18440 to avoid the hassle of writing XVECTOR (foo)->header.size.
18441 (struct vectorlike_header): New type.
18442 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
18443 object, to help avoid aliasing.
18444 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
18445 (SUBRP): Likewise, since Lisp_Subr is a special case.
18446 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
18447 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
18448 (struct Lisp_Hash_Table): Combine first two members into a single
18449 struct vectorlike_header member. All uses of "size" and "next" members
18450 changed to be "header.size" and "header.next".
18451 * buffer.h (struct buffer): Likewise.
18452 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
18453 * frame.h (struct frame): Likewise.
18454 * process.h (struct Lisp_Process): Likewise.
18455 * termhooks.h (struct terminal): Likewise.
18456 * window.c (struct save_window_data, struct saved_window): Likewise.
18457 * window.h (struct window): Likewise.
18458 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
18459 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
18460 * buffer.c (init_buffer_once): Likewise.
18461 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
18463 * process.c (Fformat_network_address): Use local var for size,
18466 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
18468 Make the Lisp reader and string-to-float more consistent (Bug#8525)
18469 * data.c (atof): Remove decl; no longer used or needed.
18470 (digit_to_number): Move to lread.c.
18471 (Fstring_to_number): Use new string_to_number function, to be
18472 consistent with how the Lisp reader treats infinities and NaNs.
18473 Do not assume that floating-point numbers represent EMACS_INT
18474 without losing information; this is not true on most 64-bit hosts.
18475 Avoid double-rounding errors, by insisting on integers when
18476 parsing non-base-10 numbers, as the documentation specifies.
18477 * lisp.h (string_to_number): New decl, replacing ...
18478 (isfloat_string): Remove.
18479 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
18480 (read1): Do not accept +. and -. as integers; this
18481 appears to have been a coding error. Similarly, do not accept
18482 strings like +-1e0 as floating point numbers. Do not report
18483 overflow for integer overflows unless the base is not 10 which
18484 means we have no simple and reliable way to continue.
18485 Break out the floating-point parsing into a new
18486 function string_to_number, so that Fstring_to_number parses
18487 floating point numbers consistently with the Lisp reader.
18488 (digit_to_number): Move here from data.c. Make it static inline.
18489 (E_CHAR, EXP_INT): Remove, replacing with ...
18490 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
18491 (string_to_number): New function, replacing isfloat_string.
18492 This function checks for valid syntax and produces the resulting
18493 Lisp float number too. Rework it so that string-to-number
18494 no longer mishandles examples like "1.0e+". Use strtoumax,
18495 so that overflow for non-base-10 numbers is reported only when
18496 there's no portable and simple way to convert to floating point.
18498 * textprop.c (set_text_properties_1): Rewrite for clarity,
18499 and to avoid GCC warning about integer overflow.
18501 * intervals.h (struct interval): Use EMACS_INT for members
18502 where EMACS_UINT might cause problems. See
18503 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
18504 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
18505 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
18507 (offset_intervals): Tell GCC not to worry about length overflow
18508 when negating a negative length.
18510 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
18511 (overrun_check_free): Likewise.
18513 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
18514 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
18517 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18518 (gnutls_make_error): Rename local to avoid shadowing.
18519 (gnutls_emacs_global_deinit): ifdef out; not used.
18520 (Fgnutls_boot): Use const for pointer to readonly storage.
18521 Comment out unused local. Fix pointer signedness problems.
18523 * lread.c (openp): Don't stuff size_t into an 'int'.
18524 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
18525 about possible signed overflow.
18527 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18528 (GDK_KEY_g): Don't define if already defined.
18529 (xg_prepare_tooltip): Avoid pointer signedness problem.
18530 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
18532 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
18533 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
18535 * xfns.c (Fx_window_property): Simplify a bit,
18536 to make a bit faster and to avoid GCC 4.6.0 warning.
18537 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
18539 * fns.c (internal_equal): Don't assume size_t fits in int.
18541 * alloc.c (compact_small_strings): Tighten assertion a little.
18543 Replace pEd with more-general pI, and fix some printf arg casts.
18544 * lisp.h (pI): New macro, generalizing old pEd macro to other
18545 conversion specifiers. For example, use "...%"pI"d..." rather
18546 than "...%"pEd"...".
18547 (pEd): Remove. All uses replaced with similar uses of pI.
18548 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
18549 * alloc.c (check_pure_size): Don't overflow by converting size to int.
18550 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
18551 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
18552 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
18553 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
18554 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
18556 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
18557 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
18558 * print.c (safe_debug_print, print_object): Likewise.
18559 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
18561 Use pI instead of if-then-else-abort. Use %p to avoid casts,
18562 avoiding the 0 flag, which is not portable.
18563 * process.c (Fmake_network_process): Use pI to avoid cast.
18564 * region-cache.c (pp_cache): Likewise.
18565 * xdisp.c (decode_mode_spec): Likewise.
18566 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
18567 behavior on 64-bit hosts with printf arg.
18568 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
18569 (x_stop_queuing_selection_requests): Likewise.
18570 (x_get_window_property): Don't truncate byte count to an 'int'
18573 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
18574 here, since it parses constructs like leading '-' and spaces,
18575 which are not wanted; and it overflows with large numbers.
18576 Instead, simply match F[0-9]+, which is what is wanted anyway.
18578 * alloc.c: Remove unportable assumptions about struct layout.
18579 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
18580 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
18581 (allocate_vectorlike, make_pure_vector): Use the new macros,
18582 plus offsetof, to remove unportable assumptions about struct layout.
18583 These assumptions hold on all porting targets that I know of, but
18584 they are not guaranteed, they're easy to remove, and removing them
18585 makes further changes easier.
18587 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
18588 This doesn't fix a bug but makes the code clearer.
18589 (string_overrun_cookie): Now const. Use initializers that
18590 don't formally overflow signed char, to avoid warnings.
18591 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
18592 can cause Emacs to crash when string overrun checking is enabled.
18593 (allocate_buffer): Don't assume sizeof (struct buffer) is a
18594 multiple of sizeof (EMACS_INT); it need not be, if
18595 alignof(EMACS_INT) < sizeof (EMACS_INT).
18596 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
18598 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
18600 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
18602 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
18604 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
18605 supposed to be handshaking. (Bug#8556)
18606 Reported by Paul Eggert <eggert@cs.ucla.edu>.
18608 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
18610 * lisp.h (Qdebug): List symbol.
18611 * eval.c (Qdebug): Restore global linkage.
18612 * keyboard.c (debug-on-event): New variable.
18613 (handle_user_signal): Break into debugger when debug-on-event
18614 matches the current signal symbol.
18616 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
18618 * alloc.c (check_sblock, check_string_bytes)
18619 (check_string_free_list): Convert to standard C.
18621 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
18623 * w32.c (emacs_gnutls_push): Fix typo.
18625 2011-04-25 Eli Zaretskii <eliz@gnu.org>
18627 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
18628 "cast to pointer from integer of different size".
18630 Improve doprnt and its use in verror. (Bug#8545)
18631 * doprnt.c (doprnt): Document the set of format control sequences
18632 supported by the function. Use SAFE_ALLOCA instead of always
18635 * eval.c (verror): Don't limit the buffer size at size_max-1, that
18636 is one byte too soon. Don't use xrealloc; instead xfree and
18639 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
18641 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
18644 * gnutls.c: Renamed global_initialized to
18645 gnutls_global_initialized. Added internals for the
18646 :verify-hostname-error, :verify-error, and :verify-flags
18647 parameters of `gnutls-boot' and documented those parameters in the
18648 docstring. Start callback support.
18649 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
18650 unless a fatal error occurred. Call gnutls_alert_send_appropriate
18651 on error. Return error code.
18652 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
18653 (emacs_gnutls_read): Likewise.
18654 (Fgnutls_boot): Return handshake error code.
18655 (emacs_gnutls_handle_error): New function.
18656 (wsaerror_to_errno): Likewise.
18658 * w32.h (emacs_gnutls_pull): Add prototype.
18659 (emacs_gnutls_push): Likewise.
18661 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
18662 (emacs_gnutls_push): Likewise.
18664 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)

18979 * process.c (send_process): Adjust to the new signatures of
18980 emacs_write and emacs_gnutls_write. Do not attempt to store

19173 * font.c (font_close_object): Now static.
19174 * font.h (font_close_object): Remove.
19175 * fontset.c (FONTSET_OBJLIST): Remove.
19176 (free_realized_fontset) #if-0 the body, which does nothing.

19178 * fontset.h (face_suitable_for_char_p): Remove decl.
19179 * xfaces.c (face_at_string_position):
19180 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,
19181 since 0 is always ASCII.
19183 * fns.c (weak_hash_tables): Now static.
19185 * fileio.c: Make symbols static if they're not exported.

19204 * editfns.c, lisp.h (get_operating_system_release): Remove.
19205 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
19206 worth the hassle of breaking this out.
19208 * xterm.c: Make symbols static if they're not exported.
19209 (x_raise_frame, x_lower_frame, x_wm_set_window_state):

19312 * buffer.c (buffer_count): Remove unused var.

19321 * atimer.h (run_all_atimers): Remove; not exported.
19323 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
19324 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
19325 was inaccessible from Lisp.
19326 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
19327 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
19329 alloc.c: Import and export fewer symbols, and remove unused items.
19330 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
19332 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
19333 it's not optimized away by whole-program optimization.
19334 (message_enable_multibyte, free_misc): Remove.
19335 (catchlist, handlerlist, mark_backtrace):
19336 Declare only if BYTE_MARK_STACK.

19345 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
19346 (mark_backtrace): Define only if BYTE_MARK_STACK.
19347 * xdisp.c (message_enable_multibyte): Now static.
19349 Declare Lisp_Object Q* variables to be 'static' if not exported.
19350 This makes it easier for human readers (and static analyzers)
19351 to see whether these variables are used from other modules.
19352 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
19353 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:

19362 Remove decls of unexported vars.
19363 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
19365 * lisp.h (DEFINE_FUNC): Make sname 'static'.
19367 Make Emacs functions such as Fatom 'static' by default.
19368 This makes it easier for human readers (and static analyzers)
19369 to see whether these functions can be called from other modules.
19370 DEFUN now defines a static function. To make the function external
19371 so that it can be used in other C modules, use the new macro DEFUE.
19372 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
19373 (Finit_image_library):
19374 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
19375 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
19376 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
19377 Remove decls, since these functions are now static.
19378 (Funintern, Fget_internal_run_time): New decls, since these functions
19379 were already external.
19381 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
19382 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

19388 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
19389 Mark functions with DEFUE instead of DEFUN,
19390 if they are used in other modules.
19391 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
19392 decls for now-static functions.
19393 * buffer.h (Fdelete_overlay): Remove decl.
19394 * callproc.c (Fgetenv_internal): Mark as internal.
19395 * composite.c (Fremove_list_of_text_properties): Remove decl.

19403 * image.c (Finit_image_library): New forward static decl.
19404 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
19405 * intervals.h (Fprevious_property_change):
19406 (Fremove_list_of_text_properties): Remove decls.
19407 * keyboard.c (Fthis_command_keys): Remove decl.
19408 (Fcommand_execute): New forward static decl.

19424 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
19426 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
19429 2011-04-13 Eli Zaretskii <eliz@gnu.org>
19431 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
19432 when at ZV. (Bug#8487)
19434 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
19436 * charset.c (Fclear_charset_maps): Use xfree instead of free.
19438 * keyboard.c (parse_tool_bar_item): Likewise.
19439 * sound.c (sound_cleanup, alsa_close): Likewise.
19440 * termcap.c (tgetent): Likewise.
19441 * xfns.c (x_default_font_parameter): Likewise.
19442 * xsettings.c (read_and_apply_settings): Likewise.
19444 * alloc.c (overrun_check_malloc, overrun_check_realloc)
19445 (overrun_check_free): Protoize.
19447 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
19449 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
19450 since callers should never pass a negative size.
19451 Change the signature to match that of plain 'read' and 'write'; see
19452 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
19453 * lisp.h: Update prototypes of emacs_write and emacs_read.
19455 2011-04-11 Eli Zaretskii <eliz@gnu.org>
19457 * xdisp.c (redisplay_window): Don't try to determine the character
19458 position of the scroll margin if the window start point w->startp
19459 is outside the buffer's accessible region. (Bug#8468)
19461 2011-04-10 Eli Zaretskii <eliz@gnu.org>
19463 Fix write-region and its subroutines for buffers > 2GB.
19464 * fileio.c (a_write, e_write): Modify declaration of arguments and
19465 local variables to support buffers larger than 2GB.
19466 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
19468 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
19469 argument, local variables, and return value.
19471 * lisp.h: Update prototypes of emacs_write and emacs_read.
19473 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
19475 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
19477 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
19479 Fix more problems found by GCC 4.6.0's static checks.
19481 * xdisp.c (vmessage): Use a better test for character truncation.
19483 * charset.c (load_charset_map): <, not <=, for optimization,
19484 and to avoid potential problems with integer overflow.
19485 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
19486 * casetab.c (set_identity, shuffle): Likewise.
19487 * editfns.c (Fformat): Likewise.
19488 * syntax.c (skip_chars): Likewise.
19490 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
19491 This also lets GCC 4.6.0 generate slightly better loop code.
19493 * callint.c (Fcall_interactively): <, not <=, for optimization.
19494 (Fcall_interactively): Count the number of arguments produced,
19495 not the number of arguments given. This is simpler and lets GCC
19496 4.6.0 generate slightly better code.
19498 * ftfont.c: Distingish more carefully between FcChar8 and char.
19499 The previous code passed unsigned char * to a functions like
19500 strlen and xstrcasecmp that expect char *, which does not
19501 conform to the C standard.
19502 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
19503 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
19504 char * when the C standard requires it.
19506 * keyboard.c (read_char): Remove unused var.
19508 * eval.c: Port to Windows vsnprintf (Bug#8435).
19509 Include <limits.h>.
19510 (SIZE_MAX): Define if the headers do not.
19511 (verror): Do not give up if vsnprintf returns a negative count.
19512 Instead, grow the buffer. This ports to Windows vsnprintf, which
19513 does not conform to C99. Problem reported by Eli Zaretskii.
19514 Also, simplify the allocation scheme, by avoiding the need for
19515 calling realloc, and removing the ALLOCATED variable.
19517 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
19519 Remove invocations of doprnt, as Emacs now uses vsnprintf.
19520 But keep the doprint source code for now, as we might revamp it
19521 and use it again (Bug#8435).
19522 * lisp.h (doprnt): Remove.
19523 * Makefile.in (base_obj): Remove doprnt.o.
19524 * deps.mk (doprnt.o): Remove.
19526 error: Print 32- and 64-bit integers portably (Bug#8435).
19527 Without this change, on typical 64-bit hosts error ("...%d...", N)
19528 was used to print both 32- and 64-bit integers N, which relied on
19529 undefined behavior.
19530 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
19531 * lisp.h (error, verror): Mark as printf-like functions.
19532 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
19533 Report overflow in size calculations when allocating printf buffer.
19534 Do not truncate output string at its first null byte.
19535 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
19536 Truncate the output at a character boundary, since vsnprintf does not
19538 * charset.c (check_iso_charset_parameter): Convert internal
19539 character to string before calling 'error', since %c now has the
19541 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
19542 overflow when computing char to be passed to 'error'. Do not
19543 pass Lisp_Object to 'error'; pass the integer instead.
19544 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
19545 formatted with plain %d.
19547 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.

19682 This avoids several warnings with gcc -Wstrict-overflow.
19683 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
19684 directly, rather than having caller test rule sign. This avoids
19685 some unnecessary tests.
19686 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
19687 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
19688 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.

19705 since the condition is always true at first.
19707 * intervals.c (graft_intervals_into_buffer): Mark var as used.

19738 * eval.c (funcall_lambda): Rename local to avoid shadowing.
19740 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
19741 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
19742 can always succeed if overflow has undefined behavior.
19744 * search.c (boyer_moore, wordify): Remove vars set but not used.
19745 (wordify): Omit three unnecessary tests.
19747 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

19775 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
19776 that are set but not used.
19778 * xfns.c (make_invisible_cursor): Don't return garbage
19779 if XCreateBitmapFromData fails (Bug#8410).
19781 * xselect.c (x_get_local_selection, x_handle_property_notify):
19782 Remove vars that are set but not used.
19784 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

19806 that is set but not used.
19808 * print.c (print_object): Remove var that is set but not used.
19810 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
19811 The gnulib version avoids calling malloc in the usual case,
19812 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
19813 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
19814 * filelock.c (current_lock_owner): Likewise.
19815 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
19816 * sysdep.c: Include allocator.h, careadlinkat.h.
19817 (emacs_no_realloc_allocator): New static constant.
19818 (emacs_readlink): New function.
19819 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
19820 ../lib/careadlinkat.h.
19822 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
19824 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
19825 first non-nil return value).

19841 (get_per_char_metric): Remove parameter `f', unused since
19842 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

19887 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
19888 (FletX, Flet): Obey lexical binding.
19889 (Fcommandp): Handle closures.
19890 (Feval): New `lexical' arg.
19891 (eval_sub): New function extracted from Feval. Use it almost
19892 everywhere where Feval was used. Look up vars in lexical env.
19894 (Ffunctionp): Move from subr.el.

19896 (apply_lambda): Remove `eval_flags'.
19897 (funcall_lambda): Handle closures and new byte-code-functions.
19898 (Fspecial_variable_p): New function.
19899 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,

19902 * doc.c (Fdocumentation, store_function_docstring):
19903 * data.c (Finteractive_form): Handle closures.
19905 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
19908 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):

19926 (redisplay_window): Even when falling back on "recentering",
19927 position point in the window according to scroll-conservatively,
19928 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
19930 (try_scrolling): When point is above the window, allow searching
19931 as far as scroll_max, or one screenful, to compute vertical
19932 distance from PT to the scroll margin position. This prevents
19933 try_scrolling from unnecessarily failing when
19934 scroll-conservatively is set to a value slightly larger than the
19935 window height. Clean up the case of PT below the margin at bottom
19936 of window: scroll_max can no longer be INT_MAX. When aggressive
19937 scrolling is in use, don't let point enter the opposite scroll
19938 margin as result of the scroll.
19939 (syms_of_xdisp) <scroll-conservatively>: Document the
19940 threshold of 100 lines for never-recentering scrolling.

19988 Don't assume string length fits in int.
19989 (keyremap_step, read_key_sequence): Use size_t for sizes.

20007 * keyboard.c (syms_of_keyboard): Use the same style as later
20008 in this function when indexing through an array. This also
20009 works around GCC bug 48267.
20011 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
20013 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
20015 * chartab.c (sub_char_table_ref_and_range): Redo for slight
20016 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
20018 * keyboard.c, keyboard.h (num_input_events): Now size_t.
20019 This avoids undefined behavior on integer overflow, and is a bit
20020 more convenient anyway since it is compared to a size_t variable.
20022 Variadic C functions now count arguments with size_t, not int.
20023 This avoids an unnecessary limitation on 64-bit machines, which
20024 caused (substring ...) to crash on large vectors (Bug#8344).
20025 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
20026 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
20027 All variadic functions and their callers changed accordingly.

20030 * editfns.c (general_insert_function): Likewise.
20031 * eval.c (struct backtrace.nargs, interactive_p)
20032 (internal_condition_case_n, run_hook_with_args, apply_lambda)
20033 (funcall_lambda, mark_backtrace): Likewise.
20034 * fns.c (concat): Likewise.
20035 * frame.c (x_set_frame_parameters): Likewise.
20036 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
20037 0 if not found, not -1. All callers changed.
20039 * alloc.c (garbage_collect): Don't assume stack size fits in int.
20040 (stack_copy_size): Now size_t, not int.
20041 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

20050 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
20051 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

20061 * keyboard.c (safe_run_hook_funcall): New function.
20062 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
20063 don't set the hook to nil, but remove the offending function instead.
20064 (Qcommand_hook_internal): Remove, unused.
20065 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
20066 Vcommand_hook_internal.
20068 * eval.c (enum run_hooks_condition): Remove.
20069 (funcall_nil, funcall_not): New functions.
20070 (run_hook_with_args): Call each function through a `funcall' argument.

20080 * print.c (strout): Remove parameter `multibyte', unused since
20081 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
20083 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
20084 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
20085 All callers changed.
20087 * w32.c (_wsa_errlist): Use braces for struct initializers.

20097 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
20098 All callers changed.
20100 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
20102 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

20131 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
20133 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
20135 * w32.c (read_unc_volume): Use parameter `henum', instead of
20136 global variable `wget_enum_handle'.
20138 * keymap.c (describe_vector): Remove parameters `indices' and
20139 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

20245 * callint.c (Fcall_interactively):
20246 * buffer.c (Fkill_all_local_variables):
20247 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
20249 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
20250 unconditionally since it does the check itself.
20252 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
20254 Fix more problems found by GCC 4.5.2's static checks.
20256 * coding.c (encode_coding_raw_text): Avoid unnecessary test
20257 the first time through the loop, since we know p0 < p1 then.
20258 This also avoids a gcc -Wstrict-overflow warning.
20260 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
20261 leading to a memory leak, possible in functions like
20262 load_charset_map_from_file that can allocate an unbounded number
20263 of objects (Bug#8318).
20265 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
20266 that could (at least in theory) be that large.
20268 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
20269 This is less likely to overflow, and avoids undefined behavior if
20270 overflow does occur. All callers changed. Use strtoul to scan
20271 for the unsigned long integer.
20272 (pint2hrstr): Simplify and tune code slightly.
20273 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

20288 * process.c (Fmake_network_process): Use socklen_t, not int,
20289 where POSIX says socklen_t is required in portable programs.
20290 This fixes a porting bug on hosts like 64-bit HP-UX, where
20291 socklen_t is wider than int (Bug#8277).
20292 (Fmake_network_process, server_accept_connection):
20293 (wait_reading_process_output, read_process_output):
20296 * process.c: Rename or move locals to avoid shadowing.

20303 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
20304 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
20306 Make tparam.h and terminfo.c consistent.
20307 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
20308 Include tparam.h instead, since it declares them.
20309 * cm.h (PC): Remove extern decl; tparam.h now does this.
20310 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
20311 * terminfo.c: Include tparam.h, to check interfaces.
20312 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
20313 (tparam): Adjust signature to match interface in tparam.h;
20314 this removes some undefined behavior. Check that outstring and len
20315 are zero, which they always are with Emacs.
20316 * tparam.h (PC, BC, UP): New extern decls.
20318 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
20319 (xftfont_open): Rename locals to avoid shadowing.

20324 (ftfont_list): Remove unused local.
20325 (get_adstyle_property, ftfont_pattern_entity):
20326 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
20327 Rename locals to avoid shadowing.
20329 * xfont.c (xfont_list_family): Mark var as initialized.
20331 * xml.c (make_dom): Now static.
20333 * composite.c (composition_compute_stop_pos): Rename local to
20335 (composition_reseat_it): Remove unused locals.
20336 (find_automatic_composition, composition_adjust_point): Likewise.
20337 (composition_update_it): Mark var as initialized.
20338 (find_automatic_composition): Mark vars as initialized,
20339 with a FIXME (Bug#8290).
20341 character.h: Rename locals to avoid shadowing.
20342 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
20343 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
20344 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
20345 (BUF_DEC_POS): Be more systematic about renaming local temporaries
20346 to avoid shadowing.
20348 * textprop.c (property_change_between_p): Remove; unused.
20350 * intervals.c (interval_start_pos): Now static.
20352 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
20354 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
20355 Rename locals to avoid shadowing.
20357 * sound.c (wav_play, au_play, Fplay_sound_internal):
20358 Fix pointer signedness.
20359 (alsa_choose_format): Remove unused local var.
20360 (wav_play): Initialize a variable to 0, to prevent undefined
20361 behavior (Bug#8278).
20363 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
20365 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
20367 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
20368 clobbering (Bug#8298).
20369 * sysdep.c (sys_subshell): Likewise.
20370 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
20372 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
20373 This should get cleaned up, so that child_setup has the
20374 same signature on all platforms.
20376 * callproc.c (call_process_cleanup): Now static.
20377 (relocate_fd): Rename locals to avoid shadowing.
20379 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
20381 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
20382 not to be necessary, and produces flickering.
20384 2011-03-20 Glenn Morris <rgm@gnu.org>
20386 * config.in: Remove file.
20388 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
20390 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
20391 are now in src/globals.h.

20418 (sigchld_handler): Now static.
20420 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
20421 That way, the code declares only the vars that it needs.
20422 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
20423 * s/cygwin.h (PTY_ITERATION): Likewise.
20424 * s/darwin.h (PTY_ITERATION): Likewise.

20427 * s/irix6-5.h (PTY_OPEN): Declare stb, to loosen coupling.
20428 * process.c (allocate_pty): Don't declare stb unless it's needed.
20430 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
20431 (CONSTANTLIM): Remove; unused.
20432 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
20433 Define only if needed.
20435 * unexelf.c (unexec): Name an expression,
20436 to avoid gcc -Wbad-function-cast warning.
20437 Use a different way to cause a compilation error if anyone uses
20438 n rather than nn, a way that does not involve shadowing.
20439 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
20441 * deps.mk (unexalpha.o): Remove; unused.
20443 New file unexec.h, the (simple) interface for unexec (Bug#8267).
20444 * unexec.h: New file.
20445 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
20446 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
20447 Depend on unexec.h.
20448 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.

20507 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
20508 some of which prompt warnings from gcc -Wbad-function-cast.
20509 (Fformat_time_string, Fencode_time, Finsert_char):

20538 (Fmemory_limit): Cast sbrk's returned value to char *.
20540 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

20543 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
20545 Use functions, not macros, for up- and down-casing (Bug#8254).
20546 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
20547 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
20548 to use the following functions instead of these macros.
20549 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
20550 EMACS_INT, since callers assume the returned value fits in int.
20551 (upcase1): Likewise, for UPCASE_TABLE.
20552 (uppercasep, lowercasep, upcase): New static inline functions.
20553 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

20563 (regex_compile, re_match_2_internal): Mark locals as initialized.
20564 (RETALLOC_IF): Define only if needed.
20565 (WORDCHAR_P): Likewise. This one is never needed, but is used
20566 only in a comment talking about a compiler bug, so put inside
20567 the #if 0 of that comment.
20568 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
20569 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

20595 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
20596 New macros, so that the caller can use some names other than
20597 gcpro1, gcpro2, etc.
20598 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
20600 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
20601 argument, for consistency with GCPRO2_VAR, etc: it is now the
20602 prefix of the variable, not the variable itself. All uses
20604 * dired.c (directory_files_internal, file_name_completion):
20605 Rename locals to avoid shadowing.
20607 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
20608 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
20609 dired.c's scmp function, had undefined behavior.
20610 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
20611 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
20612 * buffer.h: ... to here, because these macros use current_buffer,
20613 and the new implementation with inline functions needs to have
20614 current_buffer in scope now, rather than later when the macros
20616 (downcase, upcase1): New static inline functions.
20617 (DOWNCASE, UPCASE1): Reimplement using these functions.
20618 This avoids undefined behavior in expressions like
20619 DOWNCASE (x) == DOWNCASE (y), which previously suffered
20620 from race conditions in accessing the global variables
20621 case_temp1 and case_temp2.
20622 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
20623 * lisp.h (case_temp1, case_temp2): Remove their decls.
20624 * character.h (ASCII_CHAR_P): Move from here ...
20625 * lisp.h: ... to here, so that the inline functions mentioned
20626 above can use them.

20630 * fileio.c (file_name_as_directory, directory_file_name):

20633 (file_name_as_directory): Use const pointers when appropriate.
20634 (Fexpand_file_name): Likewise. In particular, newdir might
20635 point at constant storage, so make it a const pointer.
20636 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
20637 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
20639 (Fset_file_times, Finsert_file_contents, auto_save_error):

20644 to avoid shadowing.
20646 * marker.c (bytepos_to_charpos): Remove; unused.
20648 * lisp.h (verify_bytepos, count_markers): New decls,
20649 so that gcc does not warn that these functions aren't declared.
20651 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
20652 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
20653 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
20654 (copy_text): Remove unused local var.

20657 (lock_file_1): Rename local to avoid shadowing.
20659 * buffer.c (fix_overlays_before): Mark locals as initialized.
20660 (fix_start_end_in_overlays): Likewise. This function should be
20661 simplified by using pointers-to-pointers, but that's a different
20663 (switch_to_buffer_1): Now static.
20664 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
20665 (report_overlay_modification): Rename locals to avoid shadowing.

20668 Fix pointer signedness issue.
20669 (sys_subshell): Mark local as volatile if checking for lint,
20670 to suppress a gcc -Wclobbered warning that does not seem to be right.
20671 (MAXPATHLEN): Define only if needed.
20673 * process.c (serial_open, serial_configure): Move decls from here ...
20674 * systty.h: ... to here, so that they can be checked.
20676 * fns.c (get_random, seed_random): Move extern decls from here ...
20677 * lisp.h: ... to here, so that they can be checked.
20679 * sysdep.c (reset_io): Now static.
20680 (wait_for_termination_signal): Remove; unused.
20682 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

20687 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
20688 (describe_map_tree):
20689 Rename locals to avoid shadowing.
20691 * keyboard.c: Declare functions static if they are not used elsewhere.

20838 For example, without this patch (encode-time 0 0 0 1 1
20839 1152921504606846976) returns the obviously-bogus value (-948597
20840 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
20841 reports time overflow. See
