3 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
4 if the child process is still running. Instead, exit the wait
5 loop and return zero. (Bug#13086)
7 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
9 * frame.h (x_char_width, x_char_height): Remove prototypes.

17 * keyboard.c (command_loop_1): Remove prototype.
18 (command_loop_2, top_level_1): Add static to match prototype.
20 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
22 Fix a recently-introduced delete-process race condition.
23 * callproc.c, process.h (record_kill_process):
24 New function, containing part of the old call_process_kill.
25 (call_process_kill): Use it.
26 This does not change call_process_kill's behavior.
27 * process.c (Fdelete_process): Use record_kill_process to fix a
28 race condition that could cause Emacs to lose track of a child.
30 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
32 Avoid code duplication between prev_frame and next_frame.
33 * frame.c (candidate_frame): New function. Add comment.
34 (prev_frame, next_frame): Use it. Adjust comment.
36 2012-12-06 Eli Zaretskii <eliz@gnu.org>
38 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
39 fails, signal an error instead of continuing with an empty
41 Encode expanded temp file pattern before passing it to mkstemp or
44 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
45 Encode the file name before passing it to dostounix_filename, in
46 case it will downcase it (under w32-downcase-file-names).
49 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
51 Minor call-process cleanups.
52 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
53 at the same time as other platforms, to simplify analysis.
54 No need for fd0_volatile since we have synch_process_fd.
55 Avoid needless emacs_close; arg is always negative.
57 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
59 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
62 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
64 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
65 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
66 and mouse_face_hidden members to a bitfields.
67 * frame.h (struct frame): Remove set-but-not-used space_width member.
68 (FRAME_SPACE_WIDTH): Remove.
69 * nsterm.m, w32term.c, xterm.c: Adjust users.
70 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
71 member. Adjust users. Convert term_initted, delete_in_insert_mode,

73 members to a bitfields.
75 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
77 Don't let call-process be a zombie factory (Bug#12980).
78 Fixing this bug required some cleanup of the signal-handling code.
79 As a side effect, this change also fixes a longstanding rare race
80 condition whereby Emacs could mistakenly kill unrelated processes,
81 and it fixes a bug where a second C-g does not kill a recalcitrant
82 synchronous process in GNU/Linux and similar platforms.
83 The patch should also fix the last vestiges of Bug#9488,
84 a bug which has mostly been fixed on the trunk by other changes.
85 * callproc.c, process.h (synch_process_alive, synch_process_death)
86 (synch_process_termsig, sync_process_retcode):
87 Remove. All uses removed, to simplify analysis and so that
88 less consing is done inside critical sections.
89 * callproc.c (call_process_exited): Remove. All uses replaced
90 with !synch_process_pid.
91 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
92 These take the role of what used to be in unwind-protect arg.
94 (block_child_signal, unblock_child_signal):
95 New functions, to avoid races that could kill innocent-victim processes.
96 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
97 (call_process_kill): Record killed processes as deleted, so that
98 zombies do not clutter up the system. Do this inside a critical
99 section, to avoid a race that would allow the clutter.
100 (call_process_cleanup): Fix code so that the second C-g works again
101 on common platforms such as GNU/Linux.
102 (Fcall_process): Create the child process in a critical section,
103 to fix a race condition. If creating an asynchronous process,
104 record it as deleted so that zombies do not clutter up the system.
105 Do unwind-protect for WINDOWSNT too, as that's simpler in the
106 light of these changes. Omit unnecessary call to emacs_close
107 before failure, as the unwind-protect code does that.
108 * callproc.c (call_process_cleanup):
109 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
110 * process.c (record_deleted_pid): New function, containing
111 code refactored out of Fdelete_process.
112 (Fdelete_process): Use it.
113 (process_status_retrieved): Remove. All callers changed to use
115 (record_child_status_change): Remove, folding its contents into ...
116 (handle_child_signal): ... this signal handler. Now, this
117 function is purely a handler for SIGCHLD, and is not called after
118 a synchronous waitpid returns; the synchronous code is moved to
119 wait_for_termination. There is no need to worry about reaping
120 more than one child now.
121 * sysdep.c (get_child_status, child_status_changed): New functions.
122 (wait_for_termination): Now takes int * status and bool
123 interruptible arguments, too. Do not record child status change;
124 that's now the caller's responsibility. All callers changed.
125 Reimplement in terms of get_child_status.
126 (wait_for_termination_1, interruptible_wait_for_termination):
127 Remove. All callers changed to use wait_for_termination.
128 * syswait.h: Include <stdbool.h>, for bool.
129 (record_child_status_change, interruptible_wait_for_termination):
131 (record_deleted_pid, child_status_changed): New decls.
132 (wait_for_termination): Adjust to API changes noted above.
134 * bytecode.c, lisp.h (Qbytecode): Remove.
135 No longer needed after 2012-11-20 interactive-p changes.
137 2012-12-03 Eli Zaretskii <eliz@gnu.org>
139 * xdisp.c (redisplay_window): If the cursor is visible, but inside
140 the scroll margin, move point outside the margin. (Bug#13055)
142 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
144 * gtkutil.c (my_log_handler): New function.
145 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).

149 * lisp.h (modify_region): Rename to...
150 (modify_region_1): ...new prototype.
151 * textprop.c (modify_region): Now static. Adjust users.
152 * insdel.c (modify_region): Rename to...
153 (modify_region_1): ...new function to work with current buffer.
154 Adjust comment and users. Use true and false for booleans.
156 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
158 * alloc.c (free_save_value): New function.
159 (safe_alloca_unwind): Use it.
160 * lisp.h (free_save_value): New prototype.
161 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
163 (save_excursion_restore): Adjust to match saved data structure.
164 Use free_save_value to offload some work from GC. Drop obsolete
167 2012-12-03 Chong Yidong <cyd@gnu.org>
169 * fileio.c (Vauto_save_list_file_name): Doc fix.
171 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
173 * w32fns.c: Remove prototype of atof.
174 (syspage_mask): Declared DWORD_PTR, for compatibility with 64-bit
176 (file_dialog_callback): Declared UINT_PTR.
178 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
181 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
182 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
185 2012-12-03 Glenn Morris <rgm@gnu.org>
187 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
189 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
191 Fix xpalloc confusion after memory is exhausted.
192 * alloc.c (xpalloc): Comment fix.
193 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
194 and signals an error, do not clear charset_table_size, as
195 charset_table is still valid.
196 * doprnt.c (evxprintf): Clear *BUF after freeing it.
198 Use execve to avoid need to munge environ (Bug#13054).
199 * callproc.c (Fcall_process):
200 * process.c (create_process):
201 Don't save and restore environ; no longer needed.
202 * callproc.c (child_setup):
203 Use execve, not execvp, to preserve environ.
205 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
207 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
209 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
211 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
212 display for sliced images (Bug#10500).

219 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
221 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
223 * xdisp.c (window_outdated): Remove eassert since it hits
224 some suspicious corner cases (see Bug#13007 and Bug#13012).

230 (buffer_shared_and_changed): ...near to its real use.
232 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
234 * callproc.c (Fcall_process): Don't misreport vfork failure.
236 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
238 * callproc.c (Fcall_process): Fix vfork portability problems.
239 Do not assume that fd[0], count, filefd, and save_environ survive
240 vfork. Fix bug whereby wrong errno value could be reported for
241 pipe failure. Some minor cleanups, too, as follows. Move buf and
242 bufsize to the context where they're needed. Change new_argv to
243 be of type char **, as this is more convenient and avoids casts.
244 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
245 Now local constants, not macros.
247 2012-11-18 Kenichi Handa <handa@gnu.org>
249 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
250 for the variable "f".

254 * font.c (font_unparse_xlfd): Exclude special characters from the
255 generating XLFD name.

297 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
298 between bpos_covered and bpos_max. This fixes cursor display when
299 several display strings follow each other.
301 * .gdbinit (pgx): If the glyph's object is a string, display the
302 pointer to string data, rather than the value of the string object
303 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
305 * indent.c (Fvertical_motion): If the starting position is covered
306 by a display string, return to one position before that, to avoid
307 overshooting it inside move_it_to. (Bug#12930)

337 _D_EXACT_NAMELEN if available, as it's faster than strlen.
338 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
339 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
340 * makefile.w32-in (DIR_H): Remove. All uses replaced with

408 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
410 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
411 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
412 dostounix_filename. Prevents crashes down the road, because
413 dostounix_filename assumes it gets a unibyte string. Reported by
414 Michel de Ruiter <michel@sentient.nl>, see

487 * w32proc.c (waitpid): Remove unused label get_result.
489 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
491 * makefile.w32-in (SYSWAIT_H): New macro.
492 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
493 ($(BLD)/sysdep.$(O)): Update dependencies.
495 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
497 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
498 * callproc.c (relocate_fd): Assume F_DUPFD.
499 * emacs.c, term.c (O_RDWR): Remove.
500 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
501 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
502 * nsterm.m: Assume <fcntl.h> exists.
503 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
504 (create_pty, Fmake_network_process, server_accept_connection)
505 (wait_reading_process_output, init_process_emacs):
507 (wait_reading_process_output): Put in a special case for WINDOWSNT
508 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
509 It's not clear this is needed, but it's a more-conservative change.
510 (create_process): Assume FD_CLOEXEC.
511 (create_process, create_pty): Assume O_NOCTTY.
512 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
513 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
514 Omit if not DOS_NT, since F_GETFL is not defined there.
515 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
516 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
518 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
519 lack it, since gnulib guarantees this.
520 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
522 2012-11-17 Eli Zaretskii <eliz@gnu.org>
524 * w32.c (faccessat): Pretend that directories have the execute bit
525 set. Emacs expects that, e.g., in files.el:cd-absolute.
527 * w32proc.c (create_child): Don't clip the PID of the child
528 process to fit into an Emacs integer, as this is no longer a
530 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
531 reaping only the process specified by PID argument, if that is
532 positive. Use PID instead of dead_child to know which process to
533 reap. Wait for the child to die only if WNOHANG is not in
535 (sys_select): Don't set dead_child.
537 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
538 as it is no longer needed.
540 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
542 (record_child_status_change): Remove the setting of
543 record_at_most_one_child for the !WNOHANG case.
545 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
547 Fix problems in ns port found by static checking.
548 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
549 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
550 not to process group.
551 (ns_select): Use emacs_write, not write, as that's more robust
552 in the presence of signals.
553 (fd_handler:): Check for read errors.
555 2012-11-16 Glenn Morris <rgm@gnu.org>
557 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
559 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
561 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
563 2012-11-16 Eli Zaretskii <eliz@gnu.org>
565 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
566 use the same value of thread handle.
567 (start_timer_thread): If the timer thread exited (due to error),
568 clean up by closing the two handles it used. Duplicate the caller
569 thread's handle here, so it gets duplicated only once, when
570 launching the timer thread. Set priority of the timer thread, not
572 (getitimer): Don't duplicate the caller thread's handle here.
575 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
577 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
580 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
582 Remove no-longer-used pty_max_bytes variable.
583 * process.c (pty_max_bytes): Remove; unused.
584 (send_process): Do not set it.
586 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
588 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
591 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
593 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
594 This follows up on the 2012-09-29 patch that removed indirection
595 for the 'function' field. Reported by Sergey Vinokurov in
596 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
598 2012-11-14 Eli Zaretskii <eliz@gnu.org>
600 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
601 different name, as the MS runtime does not have such a function,
602 and probably never will.) All callers changed. Ignore DIRFD
603 value if PATH is an absolute file name, to match Posix spec
604 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
607 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
609 * xdisp.c (echo_area_display, redisplay_internal):
610 Omit redundant check whether frame_garbaged is set.
612 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
614 Use faccessat, not access, when checking file permissions (Bug#12632).
615 This fixes a bug that has been present in Emacs since its creation.
616 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
617 which must set some sort of record. (Torek's bug report was against
618 a predecessor of GNU Emacs, but GNU Emacs happened to have the
619 same common flaw.) See Torek's Usenet posting
620 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
621 Posted: Fri Apr 8 14:18:56 1983.
622 * Makefile.in (LIB_EACCESS): New macro.
624 * callproc.c (init_callproc):
625 * charset.c (init_charset):
626 * fileio.c (check_existing, check_executable, check_writable)
628 * lread.c (openp, load_path_check):
629 * process.c (allocate_pty):
631 Use effective UID when checking permissions, not real UID.
632 * callproc.c (init_callproc):
633 * charset.c (init_charset):
634 * lread.c (load_path_check, init_lread):
635 Test whether directories are accessible, not merely whether they exist.
636 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
637 * fileio.c (check_existing, check_executable, check_writable)
639 Use symbolic names instead of integers for the flags, as they're
641 (check_writable): New arg AMODE. All uses changed.
642 Set errno on failure.
643 (Ffile_readable_p): Use faccessat, not stat + open + close.
644 (Ffile_writable_p): No need to call check_existing + check_writable.
645 Just call check_writable and then look at errno. This saves a syscall.
646 dir should never be nil; replace an unnecessary runtime check
647 with an eassert. When checking the parent directory of a nonexistent
648 file, check that the directory is searchable as well as writable, as
649 we can't create files in unsearchable directories.
650 (file_directory_p): New function, which uses 'stat' on most platforms
651 but faccessat with D_OK (for efficiency) if WINDOWSNT.
652 (Ffile_directory_p, Fset_file_times): Use it.
653 (file_accessible_directory_p): New function, which uses a single
654 syscall for efficiency.
655 (Ffile_accessible_directory_p): Use it.
656 * xrdb.c (file_p): Use file_directory_p.
657 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
658 * lread.c (openp): When opening a file, use fstat rather than
659 stat, as that avoids a permissions race. When not opening a file,
660 use file_directory_p rather than stat.
661 (dir_warning): First arg is now a usage string, not a format.
662 Use errno. All uses changed.
663 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
664 that merely introduced a race.
665 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
666 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
667 and similarly for the other O_* flags.
668 * w32.c (sys_faccessat): Rename from sys_access and switch to
669 faccessat's API. All uses changed.
670 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
671 (magic_db): Rename from magic_file_p.
672 (magic_db, search_magic_path): Return an XrmDatabase rather than a
673 char *, so that we don't have to test for file existence
674 separately from opening the file for reading. This removes a race
675 fixes a permission-checking problem, and simplifies the code.
677 (file_p): Remove; no longer needed.
679 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
681 Omit glyphs initialization at startup.
682 * dispnew.c (glyphs_initialized_initially_p): Remove.
683 (adjust_frame_glyphs_initially): Likewise. Adjust users.
684 (Fredraw_frame): Move actual code from here...
685 (redraw_frame): ...to here. Add eassert. Adjust comment.
686 (Fredraw_display): Use redraw_frame.
687 * xdisp.c (clear_garbaged_frames): Likewise.
689 2012-11-13 Eli Zaretskii <eliz@gnu.org>
691 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
692 passed to pint2str and pint2hrstr to be at most the size of the
693 frame's decode_mode_spec_buffer. This avoids crashes with very
694 large values of FIELD_WIDTH argument to decode_mode_spec.
697 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
699 Fix a race with verify-visited-file-modtime (Bug#12863).
700 Since at least 1991 Emacs has ignored an mtime difference of no
701 more than one second, but my guess is that this was to work around
702 file system bugs that were fixed long ago. Since the race is
703 causing problems now, let's remove that code.
704 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
705 whose time stamp is off by no more than a second. Insist that the
706 file time stamps match exactly.
708 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
710 * frame.h (struct frame): Convert external_tool_bar member to
711 1-bit unsigned bitfield.
712 * termhooks.h (struct terminal): Remove mouse_moved member since
713 all users are long dead. Adjust comment on mouse_position_hook.
715 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
717 Simplify by using FOR_EACH_FRAME here and there.
718 * frame.c (next_frame, prev_frame, other_visible_frames)
719 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
720 * w32term.c (x_window_to_scroll_bar): Likewise.
721 * window.c (window_list): Likewise.
722 * xdisp.c (x_consider_frame_title): Likewise.
723 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
724 * xfns.c (x_window_to_frame, x_any_window_to_frame)
725 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
726 * xmenu.c (menubar_id_to_frame): Likewise.
727 * xselect.c (frame_for_x_selection): Likewise.
728 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
729 (x_window_to_menu_bar): Likewise.
730 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
732 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
734 * data.c (Qdefalias_fset_function): Now static.
736 Another tweak to vectorlike_header change.
737 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
738 Remove, and replace all uses with ...
739 (next_in_free_list, set_next_in_free_list):
740 New functions, which respect C's aliasing rules better.
742 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
744 * window.c (list4i): Rename from 'quad'. All uses changed.
745 Needed because <sys/types.h> defines 'quad' on Solaris 10.
747 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
749 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
750 warning about mixing declarations and code in ISO C90.
752 2012-11-10 Martin Rudalics <rudalics@gmx.at>
754 * window.c (Fsplit_window_internal): Set combination limit of
755 new parent window to t iff Vwindow_combination_limit is t;
756 fixing a regression introduced with the change from 2012-09-22.
757 (Fset_window_combination_limit): Fix doc-string.
759 2012-11-10 Eli Zaretskii <eliz@gnu.org>
761 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
762 amount when the scroll margins are too large. When scrolling
763 backwards in the buffer, give up if cannot reach point or the
764 scroll margin within a reasonable number of screen lines.
765 Fixes point position in window under scroll-up/down-aggressively when
766 point is positioned many lines beyond the window top/bottom.
769 * ralloc.c (relinquish): If real_morecore fails to return memory
770 to the system, don't crash; instead, leave the last heap
771 unchanged and return. (Bug#12774)
773 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
775 * lisp.h (AUTOLOADP): New macro.
776 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
777 * data.c (Ffset): Remove special ad-advice-info handling.
778 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
780 (Finteractive_form): Simplify.
781 (Fquo): Don't insist on having at least 2 arguments.
782 (Qdefalias_fset_function): New var.
784 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
786 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
788 * nsfont.m (Qcondensed, Qexpanded): New variables.
789 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
790 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
792 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
794 Fix recently introduced crash on MS-Windows (Bug#12839).
795 * w32term.h (struct scroll_bar): Use convenient header.
796 (SCROLL_BAR_VEC_SIZE): Remove.
797 * w32term.c (x_scroll_bar_create): Use VECSIZE.
799 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
801 Tweak last vectorlike_header change.
802 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
803 vectorlike object on the free list. This is introduced to avoid
804 some (but not all) pointer casting and aliasing problems, see
805 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
806 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
808 (xvectype, xvecsize): Use them to examine Lisp_Object values.
810 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
812 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
813 been removed, so remove them here also.
815 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
817 * doc.c (Fdocumentation): Handle new property
818 dynamic-docstring-function to replace the old ad-advice-info.
820 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
822 * fns.c (Qeql, hashtest_eq): Now static.
824 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
826 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
827 * fns.c (hashfn_eq, hashfn_eql, sxhash):
828 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
829 * buffer.c (compare_overlays): Use XLI rather than XHASH.
831 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
833 Use same hash function for hashfn_profiler as for hash_string etc.
834 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
835 * lisp.h (sxhash_combine): New inline function, with the contents
836 of the old SXHASH_COMBINE.
837 * profiler.c (hashfn_profiler): Use it, instead of having a
838 special hash function containing a comparison that always yields 1.
840 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
842 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
843 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
844 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
847 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
849 * image.c (xpm_make_color_table_h): Fix compiler error because
850 make_hash_table changed.
852 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
854 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
856 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
858 Use ad-hoc comparison function for the profiler's hash-tables.
859 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
860 (make_log): Use them.
861 (handle_profiler_signal): Don't inhibit quit any longer since we don't
862 call Fequal any more.
863 (Ffunction_equal): New function.
864 (cmpfn_profiler, hashfn_profiler): New functions.
865 (syms_of_profiler): Initialize them.
866 * lisp.h (struct hash_table_test): New struct.

868 * alloc.c (mark_object): Mark hash_table_test fields of hash tables.
869 * fns.c (make_hash_table): Take a struct to describe the test.
870 (cmpfn_eql, cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
871 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
872 (hash_lookup, hash_remove_from_table): Move assertion checking of
873 hashfn result here. Check hash-equality before calling cmpfn.
874 (Fmake_hash_table): Adjust call to make_hash_table.
875 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.
876 (syms_of_fns): Initialize them.

885 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
886 value of w32-scroll-lock-modifier is neither nil nor one of the
887 known key modifiers. (Bug#12806)
889 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
891 Shrink struct vectorlike_header to the only size field.
892 * lisp.h (enum pvec_type): Avoid explicit enum member values.
894 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
895 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
896 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
897 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
898 information from the vector header. Adjust comment.

908 (enum mem_type): Adjust comment.
909 (NEXT_IN_FREE_LIST): New macro.
910 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
911 (Fmake_bool_vector): Likewise.

913 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
914 (large_vectors): Change type to struct large_vector.
915 (allocate_vector_from_block): Simplify.
916 (PSEUDOVECTOR_NBYTES): Replace with...
917 (vector_nbytes): ...new function. Adjust users.
918 (sweep_vectors): Adjust processing of large vectors.
919 (allocate_vectorlike): Likewise.
920 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
921 Add easserts. Adjust XSETPVECTYPESIZE usage.
922 (allocate_buffer): Use BUFFER_PVEC_INIT.
923 (live_vector_p): Adjust to match large vector.
924 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
925 * buffer.h (struct buffer): Add next member.
926 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
928 (FOR_EACH_BUFFER): Adjust to match struct buffer change.

934 (xvecsize): New command.
936 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
938 * keyboard.c (event_to_kboard): Do not dereference
939 frame_or_window field of SELECTION_REQUEST_EVENT
940 and SELECTION_CLEAR_EVENT events (Bug#12814).
941 * xterm.h (struct selection_input_event): Adjust comment.
943 2012-11-07 Eli Zaretskii <eliz@gnu.org>
945 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
946 such as Scroll Lock, if the respective keys are treated as
947 function keys, not as modifiers. This avoids destroying non-ASCII
948 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
950 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
952 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
954 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
956 Restore some duplicate definitions (Bug#12814).
957 This undoes part of the 2012-11-03 changes. Some people build
958 with plain -g rather than with -g3, and they need the duplicate
959 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
960 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
961 Define as macros, as well as as enums or as constants.
963 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
965 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
966 to keypad keys (Bug#12816).
968 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
970 Minor adjustments of recently-changed frame functions.
971 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
972 known to be a frame (we're in the FRAMEP branch).
973 * lisp.h (Qframep): Remove decl. frame.h declares this.
974 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
975 since they're meant for Lisp fixnum values.
977 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
979 * window.c (Fwindow_combination_limit): Revert to the only
980 required argument and adjust docstring as suggested in
981 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
982 by Martin Rudalics <rudalics@gmx.at>.
984 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
986 Widely used frame validity and checking functions.
987 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
988 * frame.c (decode_live_frame, decode_any_frame): New functions.
989 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
990 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
991 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
992 (Fframe_pointer_visible_p): Use decode_any_frame.

998 (frame_buffer_list, frame_buffer_predicate): Remove.
999 * lisp.h (frame_buffer_predicate): Remove prototype.
1000 * buffer.c (Fother_buffer): Use decode_any_frame.
1001 * xdisp.c (Ftool_bar_lines_needed): Likewise.
1002 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
1003 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
1004 (Fclose_font, Ffont_info): Use decode_live_frame.
1005 * fontset.c (check_fontset_name): Likewise.
1006 * terminal.c (Fframe_terminal): Likewise.
1007 * w32fns.c (check_x_frame): Likewise.
1008 * window.c (Fminibuffer_window, Fwindow_at)
1009 (Fcurrent_window_configuration): Likewise.

1013 * xfaces.c (frame_or_selected_frame): Remove.
1014 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
1015 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
1016 (Fframe_face_alist): Use decode_live_frame.
1017 * xfns.c (check_x_frame): Likewise.
1019 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1021 * window.c (quad): New function.
1022 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
1023 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
1024 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
1025 (Fwindow_line_height): Use it.
1026 (Fwindow_fringes): Use list3.
1027 (Fwindow_scroll_bars): Use list4.
1028 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
1029 (Fwindow_combination_limit): Allow zero number of arguments.
1031 2012-11-05 Eli Zaretskii <eliz@gnu.org>
1033 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
1035 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
1036 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
1037 file descriptor 2 for standard error. (Bug#12805)
1039 2012-11-05 Chong Yidong <cyd@gnu.org>
1041 * process.c (wait_reading_process_output): Revert previous change.
1043 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
1045 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
1046 This removes code that has been obsolete since around 1990.
1047 * callproc.c (Fcall_process):
1049 * process.c (create_process):
1050 * term.c (dissociate_if_controlling_tty):
1051 Assume setsid exists.
1052 * callproc.c (child_setup): Assume setpgid exists and behaves as
1053 per POSIX.1-1988 or later.
1054 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
1055 * emacs.c (shut_down_emacs):
1056 * sysdep.c (sys_suspend, init_foreground_group):
1057 Assume getpgrp behaves as per POSIX.1-1998 or later.
1058 * msdos.c (setpgrp): Remove.
1059 (tcgetpgrp, setpgid, setsid): New functions.
1060 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
1061 * term.c (no_controlling_tty): Remove; unused.
1062 * w32proc.c (setpgrp): Remove.
1063 (setsid, tcgetpgrp): New functions.
1065 Simplify by assuming __fpending.
1066 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
1067 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
1068 Do not assume that __fpending's result fits in int.
1070 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
1072 Remove EMACS_OUTQSIZE+sleep hack.
1073 * dispnew.c (update_frame_1): Remove hack for terminals slower
1074 than 2400 bps, which throttled Emacs by having it sleep.
1075 This code hasn't worked since at least 2007, when the multi-tty stuff
1076 was added, and anyway those old terminals are long dead.
1077 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
1078 without the dispnew.c change, as dispnew.c doesn't include systty.h.
1080 Fix data-loss with --version (Bug#9574).
1081 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
1082 as we can't assume that emacs_strerror is initialized, and strerror
1083 is good enough here.
1084 (main): Invoke atexit earlier, to catch earlier instances of
1085 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
1087 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
1089 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
1090 (keyDown): Remap keypad keys to X11 virtual key codes.
1092 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
1094 Fix data-loss with --batch (Bug#9574).
1095 * emacs.c: Include <close-stream.h>.
1096 (close_output_streams): New function.
1097 (main): Pass it to atexit, so that Emacs closes stdout and stderr
1098 and handles errors appropriately.
1099 (Fkill_emacs): Don't worry about flushing, as close_output_stream
1102 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
1103 The symptom is a diagnostic "GLib-WARNING **: In call to
1104 g_spawn_sync(), exit status of a child process was requested but
1105 SIGCHLD action was set to SIG_IGN and ECHILD was received by
1106 waitpid(), so exit status can't be returned." The diagnostic
1107 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
1108 The real bug is a race condition between Emacs and glib: Emacs
1109 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
1110 so that glib can't find it. Work around the bug by invoking
1111 waitpid only on subprocesses that Emacs itself creates.
1112 * process.c (create_process, record_child_status_change):
1113 Don't use special value -1 in pid field, as the caller now must
1114 know the pid rather than having the callee infer it.
1115 The inference was sometimes incorrect anyway, due to another race.
1116 (create_process): Set new 'alive' member if child is created.
1117 (process_status_retrieved): New function.
1118 (record_child_status_change): Use it.
1119 Accept negative 1st argument, which means to wait for the
1120 processes that Emacs already knows about. Move special-case code
1121 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
1122 processes that have already been waited for, by testing and
1123 clearing new 'alive' member.
1124 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
1125 now does this internally.
1126 (handle_child_signal): Let record_child_status_change do all
1127 the work, since we do not want to reap all exited child processes,
1128 only the child processes that Emacs itself created.
1129 * process.h (Lisp_Process): New boolean member 'alive'.
1131 Omit duplicate definitions no longer needed with gcc -g3.
1132 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
1133 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
1134 Define only as macros. There's no longer any need to also define
1135 these symbols as enums or as constants, since we now assume
1136 gcc -g3 when debugging.
1138 2012-11-03 Eli Zaretskii <eliz@gnu.org>
1140 * lisp.mk: Adjust comments to the fact that term/internal is now
1141 loaded from loadup.el.
1143 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
1144 (msdos_fatal_signal): New function.
1145 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
1148 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
1149 for GCC versions before 4.
1150 (emacs_raise): Define to call msdos_fatal_signal.
1152 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
1153 iterator when starting in the middle of a display or overlay
1156 2012-11-03 Chong Yidong <cyd@gnu.org>
1158 * process.c (wait_reading_process_output): Clean up the last
1161 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
1163 * process.c (wait_reading_process_output): Avoid a race condition
1164 with SIGIO delivery (Bug#11536).
1166 2012-11-03 Chong Yidong <cyd@gnu.org>
1168 * buffer.c (cursor_type): Untabify docstring.
1170 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1172 * frame.h (struct frame): Drop can_have_scroll_bars member
1173 which is meaningless for a long time. Adjust comments.
1174 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
1175 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
1177 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1179 * window.c (decode_next_window_args): Update window arg after
1180 calling decode_live_window and so fix crash reported at
1181 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
1182 by Juanma Barranquero <lekktu@gmail.com>.
1183 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
1184 * font.c (Ffont_at): Likewise.
1186 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
1188 * widget.c (resize_cb): New function.
1189 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
1190 (EmacsFrameResize): Check if all is up to date before changing frame
1193 2012-11-02 Eli Zaretskii <eliz@gnu.org>
1195 Implement backtrace output for fatal errors on MS-Windows.
1196 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
1197 (BACKTRACE_LIMIT_MAX): New macro.
1198 (w32_backtrace): New function.
1199 (emacs_abort): Use w32_backtrace when the user chooses not to
1200 attach a debugger. Update the text of the abort dialog.
1202 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1204 Window-related stuff cleanup here and there.
1205 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
1206 Use decode_any_window.
1207 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
1208 * xdisp.c (Fformat_mode_line): Likewise.
1209 * font.c (Ffont_at): Use decode_live_window.
1210 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
1211 * window.c (decode_next_window_args): Likewise.
1212 (decode_any_window): Remove static.
1213 * window.h (decode_any_window): Add prototype.
1214 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
1215 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
1218 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1220 Remove pad from struct input_event.
1221 * termhooks.h (struct input_event): Remove padding field.
1223 * keyboard.c (event_to_kboard): Simplify because frame_or_window
1224 member is never cons for a long time. Adjust comment.
1225 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
1226 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
1227 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
1228 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
1230 2012-11-01 Eli Zaretskii <eliz@gnu.org>
1232 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
1234 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
1236 Fix crash when using Emacs as commit editor for git (Bug#12697).
1237 * callproc.c (setpgrp): Remove macro, as we now use setpgid
1238 and it is configured in conf_post.h.
1239 (Fcall_process): Don't invoke both setsid and setpgid; the former
1240 is enough, if it exists.
1241 * callproc.c (Fcall_process, child_setup):
1242 * process.c (create_process): Use setpgid.
1243 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
1245 * dispnew.c (init_display): Initialize the foreground group
1246 if we are running a tty display.
1247 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
1248 * lisp.h (init_foreground_group): New decl.
1249 * sysdep.c (inherited_pgroup): New static var.
1250 (init_foreground_group, tcsetpgrp_without_stopping)
1251 (narrow_foreground_group, widen_foreground_group): New functions.
1252 (init_sys_modes): Narrow foreground group.
1253 (reset_sys_modes): Widen foreground group.
1255 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
1257 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
1259 2012-10-31 Martin Rudalics <rudalics@gmx.at>
1261 * minibuf.c (read_minibuf): Restore current buffer since
1262 choose_minibuf_frame calling Fset_frame_selected_window may
1263 change it (Bug#12766).
1265 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
1267 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
1269 2012-10-30 Kenichi Handa <handa@gnu.org>
1271 * font.c (Ffont_at): If WINDOW is specified and it is not
1272 displaying the current buffer, signal an error.
1274 2012-10-29 Daniel Colascione <dancol@dancol.org>
1276 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
1277 In preparation for fixing bug#12739, move these functions from
1280 * coding.h, coding.c: ... to here, and compile them only when
1281 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
1282 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
1284 2012-10-28 Eli Zaretskii <eliz@gnu.org>
1286 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
1287 (timer_loop, getitimer, setitimer): Use it instead of
1288 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
1290 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
1293 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
1295 * nsterm.m (NO_APPDEFINED_DATA): New define.
1296 (last_appdefined_event_data): New variable
1297 (last_appdefined_event): Remove.
1298 (ns_select): Initialize t from last_appdefined_event_data instead
1299 of [last_appdefined_event data1].
1300 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
1301 remove last_appdefined_event (Bug#12698).
1303 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
1305 * frame.c (x_set_font): Catch internal error.
1307 2012-10-27 Eli Zaretskii <eliz@gnu.org>
1309 Avoid overflow in w32 implementation of interval timers.
1310 When possible, for ITIMER_PROF count only times the main thread
1312 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
1313 'volatile ULONGLONG' types. All the other data which was
1314 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
1315 (GetThreadTimes_Proc): New typedef.
1316 (w32_get_timer_time): New function, returns a suitable time value
1318 (timer_loop): Enter critical section when accessing ULONGLONG
1319 values of the itimer_data struct, as these accesses are no longer
1320 atomic. Call 'w32_get_timer_time' instead of 'clock'.
1321 Remove unused variable.
1322 (init_timers): Initialize s_pfn_Get_Thread_Times.
1323 (start_timer_thread): Don't assign itimer->caller_thread here.
1324 (getitimer): Assign itimer->caller_thread here.
1325 (setitimer): Always call getitimer to get the value of ticks_now.
1326 (sys_spawnve): Avoid compiler warning about format mismatch.
1328 2012-10-26 Eli Zaretskii <eliz@gnu.org>
1330 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
1331 mouse movement events if the menu bar is active. This avoids
1332 producing a busy "hour-glass" cursor by Windows if the mouse
1333 pointer is positioned over a tooltip shown for some menu item.
1335 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
1337 Don't assume process IDs fit in int.
1338 * emacs.c (shut_down_emacs) [!DOS_NT]:
1339 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
1340 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
1341 Use pid_t, not int, to store process IDs, as 'int'
1342 is not wide enough on a few platforms (e.g., AIX and IRIX).
1344 2012-10-23 Kenichi Handa <handa@gnu.org>
1346 The following change is to make face-font-rescale-alist work
1347 correctly for non-ASCII fonts.
1349 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
1350 (font_open_for_lface): Handle Vface_font_rescale_alist.
1352 2012-10-23 Chong Yidong <cyd@gnu.org>
1354 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
1356 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
1358 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
1360 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
1362 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
1365 2012-10-21 Glenn Morris <rgm@gnu.org>
1367 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
1369 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
1371 Port to OpenBSD 5.1.
1372 * frame.c (Fmouse_position, Fmouse_pixel_position):
1373 * xdisp.c (produce_stretch_glyph):
1374 Declare local vars only when they're needed.
1375 This is clearer and avoids a warning on OpenBSD about unused vars.
1376 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
1377 This is safer, and avoids OpenBSD warnings about unused vars.
1378 * keyboard.c (record_menu_key): Remove unnecessary decl.
1379 (poll_timer): Define only if POLL_FOR_INPUT is defined.
1380 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
1381 as our definition clashes with OpenBSD's.
1382 * xfaces.c (load_face_colors, check_lface_attrs)
1383 (get_lface_attributes_no_remap, get_lface_attributes)
1384 (lface_fully_specified_p, x_supports_face_attributes_p)
1385 (tty_supports_face_attributes_p, face_fontset, realize_face)
1386 (realize_x_face, realize_tty_face):
1387 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
1388 merely Lisp_Object *. This is more informative and avoids
1389 a warning on OpenBSD about accessing beyond an object's size.
1391 2012-10-20 Chong Yidong <cyd@gnu.org>
1393 * lread.c (Fload): Doc fix (Bug#12592).

1876 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
1877 UTF-16LE strings temporarily inside non-Lisp-visible string
1880 (w32_strerror): Just what it says on the tin.
1882 * emacs.c: Make the NS fork-then-exec code for daemon-launching
1883 also run for Cygwin; both systems have the same problem with using
1884 GUI facilities in a forked child. Also call syms_of_cygw32,
1885 syms_of_w32select in correct places.
1887 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
1888 needs fork-then-exec for daemon launching.
1890 * font.h: Include frame.h.
1892 * image.c: Use the image library cache machinery only when we're
1893 compiling for native WINDOWSNT; Cygwin can use shared libraries
1894 like any other Unixlike system.
1896 * keyboard.c: Clarify a comment regarding the input loop.
1898 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
1899 functions directly instead of trying to detect at runtime that our
1900 host operating system supports them. We make this change for two
1901 reasons: Cygwin lacks support for the multibyte character
1902 conversion functions used by the legacy menu code, and Cygwin
1903 never needs to rely on non-Unicode APIs.
1905 * unexw32.c (hinst): Declare extern.
1907 * w32.c: Change header order;
1908 (w32_strerror): Move to w32fns.c because we need it for
1909 non-WINDOWSNT builds.
1911 * w32.h: Add #error macro to make sure we don't include w32.h for
1912 Cygwin builds. Remove w32select declarations.
1914 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
1915 w32fns.c. w32console.c is WINDOWSNT-only.
1917 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
1918 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
1920 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
1921 (w32_major_version, w32_minor_version, w32_build_number)
1922 (os_subtype, sound_type): Define here
1923 (w32_defined_color): Make color parameter const for consistency
1924 with other _defined_color functions.
1925 (w32_createwindow): Unconditionally call w32_init_class instead of
1926 doing so only when hprevinst is non-NULL. Plumbing hprevinst
1927 through the code is complex and unnecessary because class
1928 registration is practically free.
1929 (w32_name_of_message): New EMACSDEBUG-only function.
1930 (Fset_message_beep): Move here
1931 (Fx_open_connection): Require that the display name for Windows be
1932 "w32" for consistency, emacsclient disambiguation, and maybe, one
1933 day, multi-window-system support.
1934 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
1935 Cygwin files for W32 GUI facilities, since these clearly don't
1936 expect Cygwin names.
1937 (_DebPrint): Define.
1938 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
1939 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
1940 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
1941 (w32_last_error): Remove.
1943 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
1945 * w32heap.c (syspage_mask): Declare here.
1946 (cache_system_info): Remove.
1948 * w32inevt.c (faked_key): Define globally, not statically.
1949 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
1950 (w32_console_toggle_lock_key): Move to w32fns.c.
1952 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
1954 * w32proc.c (_DebPrint): Move to w32fns.c.
1955 * w32select.c: Include string.h, stdio.h for Cygwin.
1956 * w32select.h: New File.
1958 * w32term.c: Include io.h for non-CYGWIN builds; needed for
1960 (w32_message_fd): New variable. Under Cygwin, holds the file
1961 descriptor the system used to tell us about pending thread
1964 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
1965 that prevented compilation under non-WINDOWSNT systems.
1967 (w32_initialize): Open /dev/windows and assign it to
1968 w32_message_fd. Provide w32 feature.
1970 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
1971 (WM_EMACS_INPUT_READY): add.
1972 (prepend_msg, w32_message_fd): Declare globally.
1975 (keyboard_handle): Use only when WINDOWSNT.
1976 (notify_msg_ready): New function. Posts a message to the main
1977 thread's message queue under CYGWIN, which wakes up the main
1978 thread from select(2) by making the /dev/windows file descriptor
1979 ready. Under WINDOWSNT, it sets an event the same way the old
1982 (post, prepend_msg): Actually call notify_msg_ready instead of
1983 setting the input event directly.
1985 2012-10-07 Eli Zaretskii <eliz@gnu.org>
1987 * ralloc.c (relinquish): If a heap is ready to be relinquished,
1988 but it still has blocs in it, don't return it to the system,
1989 instead of aborting. (Bug#12402)
1991 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
1993 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
1995 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
1996 MAC_OS_X_VERSION_10_6.
1997 (syms_of_nsterm): Remove comment about Panther and above for
1999 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
2000 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
2001 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
2003 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
2004 MAC_OS_X_VERSION_10_4.
2006 * nsmenu.m (fillWithWidgetValue:): Remove code for <
2007 MAC_OS_X_VERSION_10_2.
2009 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
2011 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
2012 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
2014 * nsterm.m (ns_in_resize): Remove (Bug#12479).
2015 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
2016 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
2017 Remove ns_in_resize check.
2018 (ns_clear_frame_area): Remove resize handle code.
2020 * nsfns.m (ns_in_resize): Remove.
2021 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
2022 Remove ns_in_resize check.
2024 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
2026 Improve sys_siglist detection.
2027 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
2028 defined as a macro, as is done in Solaris.
2029 (sys_siglist_entries): New macro.
2030 (save_strsignal): Use it.
2031 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
2032 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
2034 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
2036 * nsfns.m (Fx_create_frame): Call x_default_parameter with
2037 fullscreen/Fullscreen.
2039 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
2040 tobar_height is new.
2042 * nsterm.m (x_make_frame_visible): Check for fullscreen.
2043 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
2044 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
2045 (windowDidResize:): Check for correct window if old style fullscreen.
2046 Capitalize word in comment. Remove incorrect comment.
2047 (initFrameFromEmacs:): tbar_height renamed tibar_height.
2048 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
2049 error in drawing background.
2050 (toggleFullScreen:): Remove comment. Rearrange calls.
2051 Set toolbar values to zero, save old height in tobar_height.
2052 Restore tool bar height when leaving fullscreen.
2053 (canBecomeMainWindow): New function.
2055 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
2057 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
2059 2012-10-05 Eli Zaretskii <eliz@gnu.org>
2061 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
2063 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
2064 that time stamps of directories could also be changed.
2065 Don't request the too broad GENERIC_WRITE, only the more restrictive
2066 FILE_WRITE_ATTRIBUTES access rights.
2068 * fileio.c (Fset_file_times): Special-case ignoring errors for
2069 directories only on MSDOS, not on MS-Windows.
2071 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
2073 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
2075 2012-10-04 Eli Zaretskii <eliz@gnu.org>
2077 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
2078 see whether CreateFile failed.
2080 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
2082 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
2083 to avoid similar races.
2084 * keyboard.c (pending_signals): Now bool, not int.
2086 Port timers to OpenBSD, plus check for timer failures.
2087 OpenBSD problem reported by Han Boetes.
2088 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
2090 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
2091 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
2092 like OpenBSD, which has timer_settime but does not declare it.
2093 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
2094 whether to use itimerspec-related primitives. All uses of
2095 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
2097 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2099 * profiler.c (handle_profiler_signal): Fix a malloc race
2100 that caused Emacs to hang on Fedora 17 when profiling Lisp.
2102 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
2104 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
2106 2012-10-02 Eli Zaretskii <eliz@gnu.org>
2108 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
2109 consistent with the change in return value of 'safe_strsignal'.
2111 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2113 Prefer plain 'static' to 'static inline' (Bug#12541).
2114 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
2115 (bidi_set_sor_type, bidi_push_embedding_level)
2116 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
2117 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
2118 (bidi_cache_search, bidi_cache_ensure_space)
2119 (bidi_cache_iterator_state, bidi_cache_find)
2120 (bidi_peek_at_next_level, bidi_set_paragraph_end)
2121 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
2122 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
2123 Now 'static', not 'static inline'.
2125 Count overruns when profiling; change units to ns.
2126 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
2127 Give extra weight to samples after overruns, to attempt to count
2128 the time more accurately.
2129 (setup_cpu_timer): Change sampling interval units from ms to ns, since
2130 the underlying primitives nominally do ns.
2131 (Fprofiler_cpu_start): Document the change. Mention that
2132 the sampling intervals are only approximate.
2134 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
2136 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
2138 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
2139 case for the special 0 coding-system.
2141 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
2142 (Fmake_overlay): Remove redundant tests.
2143 (fix_start_end_in_overlays): Remove redundant recentering.
2145 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
2147 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
2148 Update dependencies.
2150 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2152 Fix a malloc race condition involving strsignal.
2153 A signal can arrive in the middle of a malloc, and Emacs's signal
2154 handler can invoke strsignal, which can invoke malloc, which is
2155 not portable. This race condition bug makes Emacs hang on GNU/Linux.
2156 Fix it by altering the signal handler so that it does not invoke
2158 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
2159 * process.c (status_message): Use const pointer, in case strsignal
2160 is #defined to safe_strsignal.
2161 * sysdep.c (sys_siglist, init_signals): Always define and
2162 initialize a substitute sys_siglist if the system does not define
2163 one, even if HAVE_STRSIGNAL.
2164 (safe_strsignal): Rename from strsignal. Always define,
2165 using sys_siglist. Return a const pointer.
2166 * syssignal.h (safe_strsignal): New decl.
2167 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
2169 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2171 * w32proc.c (timer_loop): Fix code that waits for timer
2172 expiration, to avoid high CPU usage.
2174 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
2176 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
2177 (sweep_weak_table): Remove redundant prototypes.
2179 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
2181 * emacs.c: Move the inclusion of TERM_HEADER after including
2182 windows.h on WINDOWSNT. This avoids compilation problems with
2185 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2187 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
2188 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
2189 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
2190 as the previous version used 'void *'.
2192 * ralloc.c (ROUNDUP): Fix last change.
2193 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
2196 * w32proc.c <disable_itimers>: New static flag.
2197 (init_timers): Initialize it to zero, after creating the critical
2198 sections used by the timer threads.
2199 (term_timers): Set to 1 before deleting the critical sections.
2200 (getitimer, setitimer): If disable_itimers is non-zero, return an
2201 error indication without doing anything. Reported by Fabrice
2202 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
2203 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
2205 [!HAVE_SETITIMER]: Behave as the previous version that didn't
2208 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
2209 term_ntproc after all the other bookkeeping, to get timers working
2210 as long as possible.
2212 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2214 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
2215 Suggested by Juri Linkov in
2216 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
2218 Prefer plain 'static' to 'static inline' (Bug#12541).
2219 With static functions, modern compilers inline pretty well by
2220 themselves; advice from programmers often hurts as much as it helps.
2221 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
2222 this change shrinks the text size of the Emacs executable by 1.1%
2223 without affecting CPU significantly in my benchmark.
2224 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)
2225 (live_float_p, live_misc_p, live_vector_p, live_buffer_p)
2226 (mark_maybe_object, mark_maybe_pointer, bounded_number):

2299 (x_set_glyph_string_clipping, x_clear_glyph_string_rect):
2300 Now 'static', not 'static inline'.
2303 (bidi_copy_it): Do the whole copy with a single memcpy.
2304 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
2306 Revert the FOLLOW-SYMLINKS change for file-attributes.
2307 Doing it right would require several changes to Tramp, and there's
2308 not enough time to get that tested before the freeze today.
2309 * dired.c (directory_files_internal, Ffile_attributes):
2312 * frame.c (x_report_frame_params): Port better to wider ints.
2313 Do not assume that EMACS_UINT is the same width as uprintmax_t,
2314 or that pointers can be printed in 15 decimal digits.

2496 Suggested by Eli Zaretskii in
2497 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
2499 2012-09-30 Eli Zaretskii <eliz@gnu.org>
2501 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
2502 HAVE_TIMER_SETTIME is defined.
2504 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
2506 Profiler improvements: more-accurate timers, overflow checks.
2507 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
2508 signal.h, setjmp.h. Include systime.h instead.
2509 (saturated_add): New function.

2516 All uses changed to store the new value.
2517 (handle_profiler_signal): Rename from sigprof_handler_1,
2518 for consistency with other handlers. Do not check whether
2519 cpu_log is a hash-table if garbage collecting, since it
2520 doesn't matter in that case.

2522 for consistency with other handlers.
2523 (setup_cpu_timer): New function, with much of what used to be in
2524 Fprofiler_cpu_start. Check for out-of-range argument.
2525 Prefer timer_settime if available, and prefer
2526 thread cputime clocks, then process cputime clocks, then
2527 monotonic clocks, to the old realtime clock. Use make_timeval
2528 to round more-correctly when falling back to setitimer.
2529 (Fprofiler_cpu_start): Use it.
2530 (Fprofiler_cpu_stop): Prefer timer_settime if available.
2531 Don't assume that passing NULL as the 2nd argument of setitimer

2534 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
2535 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
2536 non-fatal signal handlers. Ignore SIGPROF on startup.
2537 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
2538 in profiler.c, since sysdep.c now uses it.
2540 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

2597 Since this stuff is now private to charset.c, there's no need for
2598 a public macro and no need to inline by hand.

2672 (sys_kill): Improve commentary.
2674 * w32.c (term_ntproc): Accept (and ignore) one argument, for
2675 consistency with a signature of a signal handler. All callers

2772 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
2773 * xfns.c (Fx_show_tip) [USE_GTK]:
2774 Use bool for boolean.
2775 * gtkutil.c (xg_update_frame_menubar):
2776 * xmenu.c (update_frame_menubar):
2777 Return void, not int, since caller ignores return value.
2778 * gtkutil.c (xg_change_toolbar_position):
2781 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
2783 * makefile.w32-in (BLOCKINPUT_H): Remove.

2800 2012-09-23 Eli Zaretskii <eliz@gnu.org>
2802 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
2803 fatal_error_backtrace.
2805 * w32proc.c (sys_kill): Undo last change: don't do anything when
2806 invoked to deliver SIGABRT to our own process. This is now
2807 handled by emacs_raise.
2809 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
2811 * w32term.c (w32_read_socket): Remove leftover reference to
2812 interrupt_input_pending.
2814 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
2816 Do not use SA_NODEFER.
2817 Problem reported by Dani Moncayo in
2818 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
2820 * sysdep.c (emacs_abort): Do not reset signal handler.
2821 * emacs.c (terminate_due_to_signal): Reset signal handler here.
2822 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
2823 wanted even on POSIXish hosts, and it doesn't work on Windows.
2825 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
2827 * xterm.c (x_term_init): Call fixup_locale before and after calling
2828 gtk_init (Bug#12392).
2830 2012-09-23 Chong Yidong <cyd@gnu.org>
2832 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
2833 Vdynamic_library_alist.
2835 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
2836 (Fgnutls_available_p): Caller changed.
2838 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
2839 (Flibxml_parse_xml_region): Likewise.
2841 * dispextern.h (struct image_type): Remove arg from init function.
2843 * image.c (Finit_image_library, lookup_image_type)
2844 (define_image_type): Remove now-unneeded second arg.
2845 (init_xpm_functions, init_png_functions, init_jpeg_functions)
2846 (init_tiff_functions, init_gif_functions, init_svg_functions):
2847 Arglist and w32_delayed_load calling convention changed.
2848 (gs_type): Remove init_gs_functions; there is no such function.
2849 (valid_image_p, make_image): Fix caller to lookup_image_type.
2851 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
2853 Simplify and avoid signal-handling races (Bug#12471).
2855 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
2856 Avoid recursive loop if there's a fatal error in the function itself.
2857 * atimer.c (pending_atimers):
2858 * blockinput.h: Don't include "atimer.h"; no longer needed.
2859 (interrupt_input_pending): Remove. All uses removed.
2860 pending_signals now counts both atimers and ordinary interrupts.
2861 This is less racy than having three separate pending-signal flags.
2862 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
2864 Rename from their upper-case counterparts BLOCK_INPUT,
2865 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
2866 INPUT_BLOCKED_P, and turn into functions. All uses changed.
2867 This makes it easier to access volatile variables more accurately.
2868 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
2869 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
2870 that's more reliable if the code is buggy and sets
2871 interrupt_input_blocked to a negative value. All uses changed.
2872 * atimer.c (deliver_alarm_signal):
2873 Remove. No need to deliver this to the parent; any thread can
2874 handle this signal now. All uses replaced by underlying handler.
2875 * atimer.c (turn_on_atimers):
2876 * dispnew.c (handle_window_change_signal):
2877 * emacs.c (handle_danger_signal):
2878 * keyboard.c (kbd_buffer_get_event):
2879 Don't reestablish signal handler; not needed with sigaction.
2880 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
2882 Rework to avoid unnecessary accesses to volatile variables.
2883 (UNBLOCK_INPUT_TO): Now a function.
2884 (totally_unblock_input, unblock_input): New decls.
2885 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
2886 (init_data): Remove. Necessary stuff now done in init_signal.
2887 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
2888 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
2889 (fatal_error_code): Remove; no longer needed.
2890 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
2891 it doesn't always backtrace. All uses changed. No need to reset
2892 signal to default, since sigaction and/or die does that for us now.
2893 Use emacs_raise (FOO), not kill (getpid (), FOO).
2894 (main): Check more-accurately whether we're dumping.
2895 Move fatal-error setup to sysdep.c
2896 * floatfns.c: Do not include "syssignal.h"; no longer needed.
2897 * gtkutil.c (xg_get_file_name, xg_get_font):
2898 Remove no-longer-needed signal-mask manipulation.
2899 * keyboard.c, process.c (POLL_FOR_INPUT):
2900 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
2901 * keyboard.c (read_avail_input): Remove.
2902 All uses replaced by gobble_input.
2903 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
2904 (kbd_buffer_store_event_hold, gobble_input):
2905 (record_asynch_buffer_change) [USABLE_SIGIO]:
2906 (store_user_signal_events):
2907 No need to mess with signal mask.
2908 (gobble_input): If blocking input and there are terminals, simply
2909 set pending_signals to 1 and return. All hooks changed to not
2910 worry about whether input is blocked.
2911 (process_pending_signals): Clear pending_signals before processing
2912 them, in case a signal comes in while we're processing.
2913 By convention callers now test pending_signals before calling us.
2914 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
2915 New functions, to support changes to blockinput.h.
2916 (handle_input_available_signal): Now extern.
2917 (reinvoke_input_signal): Remove. All uses replaced by
2919 (quit_count): Now volatile, since a signal handler uses it.
2920 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
2921 All callers changed. Block SIGINT only if not already blocked.
2922 Clear sigmask reliably, even if Fsignal returns, which it can.
2923 Omit unnecessary accesses to volatile var.
2924 (quit_throw_to_read_char): No need to restore sigmask.
2925 * keyboard.c (gobble_input, handle_user_signal):
2926 * process.c (wait_reading_process_output):
2927 Call signal-handling code rather than killing ourselves.
2928 * lisp.h: Include <float.h>, for...
2929 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
2930 (pending_signals): Now volatile.
2931 (syms_of_data): Now const if IEEE floating point.
2932 (handle_input_available_signal) [USABLE_SIGIO]:
2933 (terminate_due_to_signal, record_child_status_change): New decls.
2934 * process.c (create_process): Avoid disaster if memory is exhausted
2935 while we're processing a vfork, by tightening the critical section
2937 (send_process_frame, process_sent_to, handle_pipe_signal)
2938 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
2940 (send_process): No need for setjmp/longjmp any more, since the
2941 SIGPIPE stuff is now gone. Instead, report an error if errno
2943 (record_child_status_change): Now extern. PID and W are now args.
2944 Return void, not bool. All callers changed.
2945 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
2946 Remove. All uses removed. This bug should be fixed now in a
2948 (wait_for_termination_1): Use waitpid rather than sigsuspend,
2949 and record the child status change directly. This avoids the
2950 need to futz with the signal mask.
2951 (process_fatal_action): Move here from emacs.c.
2952 (emacs_sigaction_flags): New function, containing
2953 much of what used to be in emacs_sigaction_init.
2954 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
2955 caught by emacs, to make races less likely.
2956 (deliver_process_signal): Rename from handle_on_main_thread.
2958 (BACKTRACE_LIMIT_MAX): Now at top level.
2959 (thread_backtrace_buffer, threadback_backtrace_pointers):
2961 (deliver_thread_signal, deliver_fatal_thread_signal):
2962 New functions, for more-accurate delivery of thread-specific signals.
2963 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
2964 (deliver_arith_signal): Handle in this thread, not
2965 in the main thread, since it's triggered by this thread.
2966 (maybe_fatal_sig): New function.
2967 (init_signals): New arg DUMPING so that we can be more accurate
2968 about whether we're dumping. Caller changed.
2969 Treat thread-specific signals differently from process-general signals.
2970 Block all signals while handling fatal error; that's safer.
2971 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
2973 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
2974 Ignore SIGPIPE unless batch.
2975 (emacs_backtrace): Output backtrace for the appropriate thread,
2976 which is not necessarily the main thread.
2977 * syssignal.h: Include <stdbool.h>.
2978 (emacs_raise): New macro.
2979 * xterm.c (x_connection_signal): Remove; no longer needed
2980 now that we use sigaction.
2981 (x_connection_closed): No need to mess with sigmask now.
2982 (x_initialize): No need to reset SIGPIPE handler here, since
2983 init_signals does this for us now.
2985 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
2987 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
2988 background rect may be larger (Bug#12245).
2990 2012-09-23 Chong Yidong <cyd@gnu.org>
2992 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
2994 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
2996 * .gdbinit: Just stop at fatal_error_backtrace.
2997 See Stefan Monnier's request in
2998 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
2999 Remove no-longer-used query of system type.
3001 2012-09-22 Chong Yidong <cyd@gnu.org>
3003 * search.c (Freplace_match): Doc fix (Bug#12325).
3005 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
3007 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
3008 (Fline_end_position): Doc fix.
3010 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
3012 2012-09-22 Chong Yidong <cyd@gnu.org>
3014 * dispextern.h (struct image_type): Add new slot, storing a type
3015 initialization function.
3017 * image.c (define_image_type): Call the image initializer function
3018 if it is defined. Arguments and return value changed.
3019 (valid_image_p, make_image): Callers changed.
3020 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
3021 (gif_type, imagemagick_type, svg_type, gs_type):
3022 Add initialization functions.
3023 (Finit_image_library): Call lookup_image_type.
3024 (CHECK_LIB_AVAILABLE): Macro deleted.
3025 (lookup_image_type): Call define_image_type here, rather than via
3026 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
3027 (syms_of_image): Move define_image_type calls for xbm_type and
3028 pbm_type to lookup_image_type.
3030 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3032 * keyboard.c (timer_check_2): Move calculation of 'timers' and
3033 'idle_timers' from here ...
3034 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
3035 lists, to avoid infloops when the timer does something stupid,
3036 like reinvoke itself with the same or smaller time-out.
3039 2012-09-22 Martin Rudalics <rudalics@gmx.at>
3041 * window.c (Fsplit_window_internal): Handle only Qt value of
3042 Vwindow_combination_limit separately.
3043 (Qtemp_buffer_resize): New symbol.
3044 (Vwindow_combination_limit): New default value.
3047 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3049 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
3050 the new overlay string. (Bug#10159)
3052 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3054 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
3055 or that fprintf is async-signal-safe. POSIX doesn't require
3058 2012-09-22 Chong Yidong <cyd@gnu.org>
3060 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
3063 2012-09-22 Kenichi Handa <handa@gnu.org>
3065 * composite.c (composition_reseat_it): Handle the case that a
3066 grapheme cluster is not covered by a single font (Bug#12352).
3068 2012-09-21 Chong Yidong <cyd@gnu.org>
3070 * image.c (define_image_type): Avoid adding duplicate types to
3071 image_types (Bug#12463). Suggested by Jörg Walter.
3073 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3075 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
3076 (print_load_command_name): Add case LC_DATA_IN_CODE.
3077 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
3079 2012-09-21 Glenn Morris <rgm@gnu.org>
3081 * eval.c (Frun_hook_with_args_until_success)
3082 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
3084 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
3086 * fileio.c (Ffile_selinux_context): Only call freecon when
3087 lgetfilecon succeeded.
3088 (Fset_file_selinux_context): Likewise. (Bug#12444)
3090 2012-09-21 Eli Zaretskii <eliz@gnu.org>
3092 * xdisp.c (try_window_reusing_current_matrix): Under bidi
3093 reordering, locate the cursor by calling set_cursor_from_row; if
3094 that fails, clear the desired glyph matrix before returning a
3095 failure indication to the caller. Fixes leaving garbled display
3096 when fast scrolling with a down-key. (Bug#12403)
3097 (compute_stop_pos_backwards): Fix a typo that caused crashes while
3098 scrolling through multibyte text.
3100 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
3102 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
3103 calling mark_vectorlike since that's the one that marks the window.
3104 (mark_discard_killed_buffers): Mark the final cdr.
3105 * window.h (struct window): Move prev/next_buffers to the
3106 non-standard fields.
3107 * window.c (make_window): Initialize prev/next_buffers manually.
3109 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
3111 Omit unused arg EXPECTED from socket hooks.
3112 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
3113 * nsterm.m (ns_term_init):
3114 * termhooks.h (struct terminal.read_socket_hook):
3115 * w32inevt.c (w32_console_read_socket):
3116 * w32term.c (w32_read_socket):
3117 * xterm.c (XTread_socket):
3118 Omit unused arg EXPECTED. All callers changed.
3119 (store_user_signal_events): Return void, not int, since callers no
3120 longer care about the return value. All uses changed.
3122 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
3124 * w32gui.h (XParseGeometry): Do not declare.
3126 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
3128 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
3129 Ignore 'expected'. See Eli Zaretskii in
3130 <http://bugs.gnu.org/12471#8> (last line).
3132 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
3133 (XParseGeometry): Now static. Substitute extremal values for
3134 values that are out of range.
3136 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
3138 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
3140 * nsfns.m (XParseGeometry): Remove.
3141 (Fx_create_frame): Call x_set_offset to correctly interpret
3142 top_pos in geometry.
3144 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
3145 (Fx_parse_geometry): If there is a space in string, call
3146 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
3148 2012-09-17 Eli Zaretskii <eliz@gnu.org>
3150 * search.c (scan_buffer): Use character positions in calls to
3151 region_cache_forward and region_cache_backward, not byte
3152 positions. (Bug#12196)
3154 * w32term.c (w32_read_socket): Set pending_signals to 1, like
3155 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
3157 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
3158 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
3159 emacs_blocked_malloc, now deleted.
3161 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
3163 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
3164 The workaround was for improving performance on Solaris 2.4, but
3165 is getting in the way now. Emacs will still work if someone is
3166 still running Solaris 2.4 in a museum somewhere; Sun dropped
3167 support for Solaris 2.4 in 2003.
3168 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
3169 * process.c (create_process) [HAVE_WORKING_VFORK]:
3170 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
3171 since Emacs no longer uses vfork on that platform.
3173 2012-09-17 Glenn Morris <rgm@gnu.org>
3175 * emacs.c: Use COPYRIGHT.
3177 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
3179 Remove configure's --without-sync-input option (Bug#12450).
3180 When auditing signal-handling in preparation for cleaning it up,
3181 I found that SYNC_INPUT has race conditions and would be a real
3182 pain to fix. Since it's an undocumented and deprecated
3183 configure-time option, now seems like a good time to remove it.
3184 Also see <http://bugs.gnu.org/11080#16>.
3185 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
3186 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
3187 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3188 (malloc_hysteresis):
3189 (check_depth) [XMALLOC_OVERRUN_CHECK]:
3190 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
3191 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
3192 (dont_register_blocks, bytes_used_when_reconsidered)
3193 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
3194 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
3195 [!SYSTEM_MALLOC && !SYNC_INPUT]:
3196 Remove. All uses removed.
3197 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
3198 implementation, one that depends on whether the new macro
3199 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
3201 * atimer.c (run_timers, handle_alarm_signal):
3202 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)

3204 (handle_input_available_signal, init_keyboard):
3205 * nsterm.m (ns_read_socket):
3206 * process.c (wait_reading_process_output):
3207 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
3208 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
3210 * xterm.c (XTread_socket):
3212 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
3213 * eval.c (handling_signal): Remove. All uses removed.
3214 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
3215 All uses replaced with the SYNC_INPUT version.
3216 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
3218 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3221 * font.c (Ffont_shape_gstring): Remove unused local.
3223 2012-09-16 Glenn Morris <rgm@gnu.org>
3225 * Makefile.in (clean): No longer run nextstep's clean.
3227 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
3229 (ns-app): Move here from ns.mk, and simplify.
3230 (clean): Simplify nextstep entry.
3231 * ns.mk: Remove file.
3233 2012-09-17 Kenichi Handa <handa@gnu.org>
3235 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
3236 not covert the last few charactes.
3238 2012-09-16 Kenichi Handa <handa@gnu.org>
3240 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
3241 here, but just check the validity of glyphs in the glyph-string.
3243 2012-09-16 Martin Rudalics <rudalics@gmx.at>
3245 * window.c (Fwindow_parameter, Fset_window_parameter):
3246 Accept any window as argument (Bug#12452).
3248 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
3250 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
3251 to ns_term_init to avoid memory leak.
3253 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
3254 explicit retain/release.
3255 (ns_term_init): Only allow one display. Initialize outerpool and
3258 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3260 Port _setjmp fix to POSIXish hosts as well as Microsoft.
3261 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
3262 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
3263 the Microsoft problem in a different way, by altering ../nt/config.nt.
3265 2012-09-15 Eli Zaretskii <eliz@gnu.org>
3280 * w16select.c: Remove inclusion of setjmp.h, as it is now included
3281 by lisp.h. This completes removal of setjmp.h inclusion
3282 erroneously announced in the previous commit. (Bug#12446)
3284 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
3287 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
3288 not defined as a macro. The latter happens on MS-Windows.
3291 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3293 Port better to POSIX hosts lacking _setjmp (Bug#12446).
3294 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
3295 Some instances of '#include <setjmp.h>' removed, if the
3296 only reason for the instance was because "lisp.h" was included.
3297 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
3298 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
3299 and _longjmp with the new symbols. Emacs already uses _setjmp if
3300 available, so this change affects only POSIXish hosts that have
3301 sigsetjmp but not _setjmp, such as some versions of Solaris and
3302 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
3303 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
3304 (png_load_body) [HAVE_PNG]:
3305 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
3306 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
3307 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
3308 since PNG requires jmp_buf. This is the only exception to the
3309 general rule that we now use sys_setjmp and sys_longjmp.
3310 This exception is OK since this code does not change the signal
3311 mask or longjmp out of a signal handler.
3313 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
3315 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3316 Include "syssignal.h", for 'main_thread'.
3318 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
3320 Avoid out-of-range marker position (Bug#12426).
3321 * insdel.c (replace_range, replace_range_2):
3322 Adjust markers before overlays, as suggested by comments.
3323 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
3324 Remove redundant check before calling offset_intervals.
3326 2012-09-14 Martin Rudalics <rudalics@gmx.at>
3328 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
3329 current buffer (Bug#12387).
3331 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
3333 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
3335 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3337 Use a more backwards-compatible timer format (Bug#12430).
3338 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
3339 vector element, not from the 4th, since PSECS is now at the end.
3340 (Fcurrent_idle_time): Doc fix.
3342 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
3344 Function to mark objects and remove killed buffers at once.
3345 * alloc.c (discard_killed_buffers): Rename to ...
3346 (mark_discard_killed buffers) ... new name. Add marking
3347 of remaining objects. Fix comment. Adjust users.
3348 (mark_object): Do not touch frame buffer lists here.
3349 * frame.c (delete_frame): Reset frame buffer lists here.
3351 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3353 Better workaround for GNOME bug when --enable-gcc-warnings.
3354 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
3355 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
3356 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
3358 Simplify SIGIO usage (Bug#12408).
3359 The code that dealt with SIGIO was crufty and confusing, e.g., it
3360 played tricks like "#undef SIGIO" but these tricks were not used
3361 consistently. Simplify mostly by not #undeffing standard symbols,
3362 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
3363 or not as we please) rather than "defined SIGIO" (standard symbol
3364 that we probably shouldn't #undef).
3365 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
3366 Modules that need it can include it.
3367 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
3368 * dispextern.h (ignore_sigio): New decl.
3369 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
3370 unconditionally, since it's now a no-op if !USABLE_SIGIO.
3371 * emacs.c (shut_down_emacs):
3372 * keyboard.c (kbd_buffer_store_event_hold):
3373 Use ignore_sigio rather than invoking 'signal' directly.
3374 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
3376 (FIONREAD, SIGIO): Do not #undef.
3377 (tty_read_avail_input): Use #error rather than a syntax error.
3378 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
3379 for I_PIPE, used by SETUP_SLAVE_PTY.
3380 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
3381 * sysdep.c (croak): Remove; no longer needed. This bit of
3382 temporary code, with Fred N. Fish's comment that it's temporary,
3383 has been in Emacs since at least 1992!
3384 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
3385 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
3386 * syssignal.h (croak): Remove decl.
3387 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
3388 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
3389 now that we're termios-only.
3390 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
3391 * term.c (dissociate_if_controlling_tty): Use #error rather than
3394 Work around GCC and GNOME bugs when --enable-gcc-warnings.
3395 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
3396 to work around GNOME bug 683906.
3397 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
3398 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
3399 This works around GCC bug 54561.
3401 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
3403 More fixes for 'volatile' and setjmp/longjmp.
3404 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
3405 * image.c (struct png_load_context) [HAVE_PNG]: New type.
3406 (png_load_body) [HAVE_PNG]:
3407 (jpeg_load_body) [HAVE_JPEG]:
3408 New function, with most of the old parent function's body.
3409 (png_load) [HAVE_PNG]:
3410 (jpeg_load) [HAVE_JPEG]:
3411 Invoke the new function, to avoid longjmp munging our locals.
3412 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
3413 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
3414 longjmp is passed 2, as the C standard doesn't guarantee this.
3415 Instead, store the failure code into mgr->failure_code.
3417 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
3419 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
3420 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
3421 (syms_of_keyboard): Remove support for unread-command-char.
3423 2012-09-12 Eli Zaretskii <eliz@gnu.org>
3425 * w32proc.c (sys_kill): If PID is our process ID and the signal is
3426 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
3427 violation. (Bug#12426)
3429 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
3431 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
3433 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
3435 * eval.c: Add `inhibit-debugger'.
3436 (Qinhibit_debugger): New symbol.
3437 (call_debugger): Bind it instead of Qdebug_on_error.
3438 (maybe_call_debugger): Test Vinhibit_debugger.
3439 (syms_of_eval): Define inhibit-debugger.
3440 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
3441 (syms_of_xdisp): Remove inhibit-debug-on-message.
3443 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
3445 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
3446 If a nonvolatile local variable is written before a _longjmp to
3447 the frame containing the variable, and is read after the _longjmp,
3448 the value read is indeterminate. Some local variables of type
3449 'struct handler' and 'struct catchtag' are used in this way, so
3450 mark each of their slots as volatile if the slot can be set before
3451 _longjmp and read afterwards.
3452 * lisp.h (struct handler): var and chosen_clause are now volatile.
3453 (struct catchtag): val, next, and pdlcount are now volatile.
3455 * bidi.c (bidi_push_it, bidi_pop_it):
3456 * fns.c (copy_hash_table):
3457 * image.c (define_image_type):
3458 * keyboard.c (kbd_buffer_store_event_hold):
3459 * process.c (Fprocess_send_eof):
3460 * xfaces.c (x_create_gc) [HAVE_NS]:
3461 * xgselect.c (xg_select):
3462 Prefer assignment to memcpy when either will do.
3464 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
3465 Use pointer-to-a-pointer to simplify and avoid a NILP check each
3466 time an item is removed. No need to mark this function 'inline';
3467 the compiler knows better than we do.
3469 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
3471 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
3472 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
3473 to change_frame_size (Bug#12388).
3474 (windowDidResize:): Pass YES to updateFrameSize.
3476 * nsterm.h: Add delay parameter to updateFrameSize.
3478 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
3480 Discard killed buffers from deleted window and frame objects.
3481 This reduces an amount of references to killed buffers and
3482 helps GC to reclaim them faster.
3483 * alloc.c (discard_killed_buffers): New function.
3484 (mark_object): Use it for deleted windows and frames.
3485 (mark_object): If symbol's value is set up for a killed buffer
3486 or deleted frame, restore its global binding.
3487 * data.c (swap_in_global_binding): Add GC notice.
3488 (swap_in_symval_forwarding): Use convenient set_blv_where.
3489 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
3490 * window.h: ... to here.
3492 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
3494 Convenient macro to check whether the buffer is live.
3495 * buffer.h (BUFFER_LIVE_P): New macro.
3496 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
3497 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
3499 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3501 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
3502 composition cases (Bug#12364).
3504 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
3505 overhang of succeeding glyphs overlapping box cursor.
3507 * w32term.c (x_draw_glyph_string): Likewise.
3509 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
3511 Simplify, document, and port floating-point (Bug#12381).
3512 The porting part of this patch fixes bugs on non-IEEE platforms
3513 with frexp, ldexp, logb.
3514 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
3516 * floatfns.c: Simplify discussion of functions that Emacs doesn't
3517 support, by removing commented-out code and briefly listing the
3518 C89 functions excluded. The commented-out stuff was confusing
3519 maintenance, e.g., we thought we needed cbrt but it was commented out.
3520 (logb): Remove decl; no longer needed.
3521 (isfinite): New macro, if not already supplied.
3522 (isnan): Don't replace any existing macro.
3523 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
3524 are present on all C89 platforms.
3525 (Ffrexp): Do not special-case zero, as frexp does the right thing
3527 (Flogb): Do not use logb, as it doesn't have the desired meaning
3528 on hosts that use non-base-2 floating point. Instead, stick with
3529 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
3530 frexp, to avoid getting an unspecified result.
3532 * xdisp.c (Qinhibit_debug_on_message): Now static.
3534 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
3536 * nsterm.m (ns_update_begin): Set clip path to whole view by using
3537 NSBezierPath (Bug#12131).
3539 2012-09-10 Chong Yidong <cyd@gnu.org>
3541 * fns.c (Fdelq, Fdelete): Doc fix.
3543 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
3545 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
3546 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
3548 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
3550 * lisp.h (make_lisp_ptr): New macro to replace XSET.
3551 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
3554 2012-09-09 Eli Zaretskii <eliz@gnu.org>
3556 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
3557 left fringe if the window has a left margin. This avoids leaving
3558 traces of the cursor because its leftmost pixel is not drawn over.
3560 * dispnew.c (update_window_line): When the left margin area of a
3561 screen line is updated, set the redraw_fringe_bitmaps_p flag of
3562 that screen line. (Bug#12277)
3564 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
3566 Assume C89 or later for math functions (Bug#12381).
3567 This simplifies the code, and makes it a bit smaller and faster,
3568 and (most important) makes it easier to clean up signal handling
3569 since we can stop worring about floating-point exceptions in
3570 library code. That was a problem before C89, but the problem
3571 went away many years ago on all practical Emacs targets.
3572 * data.c, image.c, lread.c, print.c:
3573 Don't include <math.h>; no longer needed.
3574 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
3575 might be autoconfigured, as that never happens.
3577 * doprnt.c (DBL_MAX_10_EXP):
3578 * print.c (DBL_DIG):
3579 Remove. C89 or later always defines these.
3580 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
3581 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
3582 (arith_error, domain_error, domain_error2):
3583 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
3584 no longer needed -- we simply return what C returns. All uses removed.
3585 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
3587 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
3588 Remove. All uses expanded, as these macros are no longer used
3589 more than once and are now more trouble than they're worth.
3590 (Ftan): Use tan, not sin / cos.
3591 (Flogb): Assume C89 frexp.
3592 (fmod_float): Assume C89 fmod.
3593 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
3594 (init_floatfns): Remove. All uses removed.
3596 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3598 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
3599 compositeToPoint for OSX < 10.6 (Bug#12390).
3601 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
3603 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
3604 This produces more-accurate results.
3606 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3608 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
3609 changes (Bug#12088).
3611 2012-09-08 Chong Yidong <cyd@gnu.org>
3613 * syntax.c (Fstring_to_syntax): Doc fix.
3615 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3617 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
3618 in the internal border.
3619 (x_set_window_size): Remove static variables and their usage.
3620 (ns_redraw_scroll_bars): Fix NSTRACE arg.
3621 (ns_after_update_window_line, ns_draw_fringe_bitmap):
3622 Remove fringe/internal border adjustment (Bug#11052).
3623 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
3624 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
3625 (ns_fix_rect_ibw): Remove.
3626 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
3627 (ns_dumpglyphs_box_or_relief): Ditto.
3628 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
3630 (ns_dumpglyphs_image): Ditto.
3631 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
3633 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
3634 their usage. Add fringe_extended_p and its use as in other terms.
3635 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
3636 scroll bar was removed.
3637 (updateFrameSize): New function.
3638 (windowDidResize): Move code to updateFrameSize and call it.
3640 * nsterm.h (EmacsView): Add updateFrameSize.
3642 2012-09-07 Chong Yidong <cyd@gnu.org>
3644 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
3646 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
3648 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
3650 More signal-handler cleanup (Bug#12327).
3651 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
3652 Problem introduced when merging patches. Noted by Eli Zaretskii in
3653 <http://bugs.gnu.org/12327#67>.
3654 * floatfns.c: Comment fix.
3655 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
3656 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
3657 and anyway the declaration is harmless even if SIGDANGER is not defined.
3658 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
3659 defined BROKEN_FIONREAD). systty.h formerly did this, but other
3660 source files not surprisingly expected syssignal.h to define, or
3661 not define, SIGIO, and it's cleaner to do it that way, for consistency.
3662 Include <sys/ioctl.h>, for FIONREAD.
3663 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
3664 This eliminates a problem whereby other files mysteriously had
3665 to include "syssignal.h" before including "systty.h" if they
3666 wanted to use "#ifdef SIGIO".
3668 2012-09-07 Eli Zaretskii <eliz@gnu.org>
3670 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
3672 * w32.c (sigemptyset): Empty the set.
3673 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
3675 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
3677 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
3679 * alloc.c (mark_buffer): Revert unsafe marking optimization.
3680 (mark_object): Likewise for frame objects.
3682 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
3684 * syssignal.h (handle_on_main_thread): Always declare,
3685 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
3686 This ports to platforms without HAVE_PTHREAD.
3688 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
3690 Signal-handler cleanup (Bug#12327).
3691 Emacs's signal handlers were written in the old 4.2BSD style with
3692 sigblock and sigmask and so forth, and this led to some
3693 inefficiencies and confusion. Rewrite these to use
3694 pthread_sigmask etc. without copying signal sets around. Also,
3695 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
3696 'signal', and instead use functions that do not attempt to take
3697 over the system name space. This patch causes Emacs's text
3698 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
3699 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
3700 Do not include <signal.h> or "syssignal.h", as these
3701 modules do not use signals.
3702 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
3703 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
3704 Do not include <signal.h>, as "syssignal.h" does that for us now.
3705 * atimer.c (sigmask_atimers): New function.
3706 (block_atimers, unblock_atimers): New functions,
3707 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
3709 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
3710 no longer needed here.
3711 * emacs.c (main): Inspect existing signal handler with sigaction,
3712 so that there's no need to block and unblock SIGHUP.
3713 * sysdep.c (struct save_signal): New member 'action', replacing
3714 old member 'handler'.
3715 (save_signal_handlers, restore_signal_handlers):
3716 Use sigaction instead of 'signal' to save and restore.
3717 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
3718 New function. All users of 'signal' modified to use set_sighandler
3719 if they're writeonly, and to use sys_signal if they're read+write.
3720 (emacs_sigaction_init, forwarded_signal): New functions.
3721 (sys_signal): Remove. All uses replaced by calls to sigaction
3722 and emacs_sigaction_init, or by direct calls to 'signal'.
3723 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
3724 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
3725 all uses replaced by pthread_sigmask etc. calls.
3726 * syssignal.h: Include <signal.h>.
3727 (emacs_sigaction_init, forwarded_signal): New decls.
3728 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
3729 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
3730 (sigmask, sys_sigmask): Remove; no longer needed.
3731 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
3732 (sigblock, sigunblock, sigfree):
3733 (sigsetmask) [!defined sigsetmask]:
3734 Remove. All uses replaced by pthread_sigmask.
3735 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
3736 no longer need to be replaced, and its typical old uses
3737 are now done via emacs_sigaction_init and sigaction.
3738 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
3739 (sys_sigdel): Remove; unused.
3740 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
3742 2012-09-06 Eli Zaretskii <eliz@gnu.org>
3744 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
3745 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
3747 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
3749 Explicitly mark buffer_defaults and buffer_local_symbols.
3750 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
3751 mark_local_symbols here.
3752 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
3753 since special buffers aren't marked here any more.
3754 (allocate_buffer): Chain new buffer with all_buffers here...
3755 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
3757 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
3758 (syms_of_buffer): Remove staticpro of the above.
3759 (init_buffer_once): Set names for buffer_defaults and
3760 buffer_local_symbols.
3762 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
3764 Use bool for booleans in font-related modules.
3765 * font.c (font_intern_prop, font_style_to_value)
3766 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
3767 (generate_otf_features, font_check_otf_features, font_check_otf)
3768 (font_match_p, font_list_entities, font_at):
3769 * fontset.c (fontset_id_valid_p, reorder_font_vector
3770 (fontset_find_font, Fset_fontset_font)
3771 (face_suitable_for_char_p) [0]:
3772 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
3773 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
3774 (m17n_flt_initialized, ftfont_shape_by_flt):
3775 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
3776 * nsfont.m (nsfont_draw):
3777 * w32font.c (w32font_draw):
3778 * w32term.c (x_draw_glyphless_glyph_string_foreground):
3779 Use bool for booleans.
3780 * font.h: Adjust to above API changes.
3781 (struct font, struct font_driver, struct font_driver_list):
3782 Use bool for booleans.
3783 (struct font): Remove useless member encoding_type.
3785 * fontset.c, xftfont.c: Omit unnecessary static decls.
3787 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
3789 * alloc.c (mark_object): Revert window marking code
3790 since it's unsafe for the Fset_window_configuration.
3792 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
3794 Fix race conditions with signal handlers and errno (Bug#12327).
3795 Be more systematic about preserving errno whenever a signal
3796 handler returns, even if it's not in the main thread. Do this by
3797 renaming signal handlers to distinguish between signal delivery
3798 and signal handling. All uses changed.
3799 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
3800 * data.c (deliver_arith_signal): Rename from arith_error.
3801 * dispnew.c (deliver_window_change_signal): Rename from
3802 window_change_signal.
3803 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
3804 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
3805 * keyboard.c (deliver_input_available_signal): Rename from
3806 input_available_signal.
3807 (deliver_user_signal): Rename from handle_user_signal.
3808 (deliver_interrupt_signal): Rename from interrupt_signal.
3809 * process.c (deliver_pipe_signal): Rename from send_process_trap.
3810 (deliver_child_signal): Rename from sigchld_handler.
3811 * atimer.c (handle_alarm_signal):
3812 * data.c (handle_arith_signal):
3813 * dispnew.c (handle_window_change_signal):
3814 * emacs.c (handle_fatal_signal, handle_danger_signal):
3815 * keyboard.c (handle_input_available_signal):
3816 * keyboard.c (handle_user_signal, handle_interrupt_signal):
3817 * process.c (handle_pipe_signal, handle_child_signal):
3818 New functions, with the actual signal-handling code taken from the
3819 original respective signal handlers, sans the sporadic attempts to
3820 preserve errno, since that's now done by handle_on_main_thread.
3821 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
3822 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
3823 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3825 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3826 Move initialization of main_thread to sysdep.c's init_signals.
3827 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
3828 our usage, and simplifies the mainline code.
3829 (record_child_status_change): New static function, as a helper
3830 for handle_child_signal, and with most of the old child handler's
3832 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
3833 (handle_child_signal): Use the above.
3834 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3835 Moved here from emacs.c.
3836 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
3837 code moved here from emacs.c's main function.
3838 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
3839 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
3840 This lets callers save and restore errno properly.
3842 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3844 Remove redundant or unused things here and there.
3845 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
3846 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
3847 * editfns.c (Fcompare_buffer_substrings): Likewise.
3848 * frame.h (struct terminal, struct font_driver_list):
3849 Remove redundant declarations.
3850 * window.h (Qleft, Qright): Likewise.
3852 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3854 Do not mark objects from deleted buffers, windows and frames.
3855 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
3856 (mark_object): Likewise for windows and frames.
3858 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3860 * alloc.c (valid_lisp_object_p): Treat killed buffers,
3861 buffer_defaults and buffer_local_symbols as valid objects.
3862 Return special value to denote them.
3864 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
3866 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
3867 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
3868 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
3869 (file_name_absolute_p, Fsubstitute_in_file_name):
3870 (check_executable, check_writable, Ffile_accessible_directory_p)
3871 (Fset_file_selinux_context, Fdefault_file_modes)
3872 (Finsert_file_contents, choose_write_coding_system)
3873 (Fwrite_region, build_annotations, a_write, e_write)
3875 * filelock.c (boot_time_initialized, get_boot_time)
3876 (get_boot_time_1, lock_file_1, within_one_second):
3877 * floatfns.c (in_float):
3878 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
3879 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
3880 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
3881 * lisp.h (struct Lisp_Hash_Table.cmpfn):
3882 * window.c (compare_window_configurations):
3883 Use bool for booleans.
3884 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
3885 (Fdefault_file_modes): Now mode_t, not int, for modes.
3886 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
3887 (internal_delete_file): Now returns void, not a (boolean) int,
3888 since nobody was looking at the return value.
3889 * lisp.h, window.h: Adjust to above API changes.
3891 * xdisp.c (set_message): Simplify and reindent last change.
3893 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
3895 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
3897 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
3899 * eval.c (call_debugger): Make the function non-static so that we
3900 can call it from set_message.
3902 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
3903 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
3905 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3907 Give more-useful info on a fatal error (Bug#12328).
3908 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
3909 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
3910 of doing the work ourselves.
3911 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
3912 do most of the work.
3913 (fatal_error_backtrace): New function, taken from the guts
3914 of the old fatal_error_signal, but with a new option to output
3916 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
3917 info about the signal than just its number.
3918 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
3919 * sysdep.c: Include <execinfo.h>
3920 (emacs_backtrace): New function, taken partly from the previous
3921 code of the 'die' function.
3922 (emacs_abort): Call fatal_error_backtrace rather than abort.
3924 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
3926 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
3927 eager (load-time) macro-expansion.
3928 * lisp.mk (lisp): Add macroexp.
3930 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3932 Simplify redefinition of 'abort' (Bug#12316).
3933 Do not try to redefine the 'abort' function. Instead, redo
3934 the code so that it calls 'emacs_abort' rather than 'abort'.
3935 This removes the need for the NO_ABORT configure-time macro
3936 and makes it easier to change the abort code to do a backtrace.
3937 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
3938 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
3939 Remove; sysdep.c's emacs_abort now takes its place.
3940 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
3941 'abort' changed to use 'emacs_abort'.
3942 * msdos.c (dos_abort) [defined abort]: Remove; not used.
3943 (abort) [!defined abort]: Rename to ...
3944 (emacs_abort): ... new name.
3945 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
3946 the place of the old 'abort' in emacs.c.
3947 * w32.c, w32fns.c (abort): Do not #undef.
3948 * w32.c (emacs_abort): Rename from w32_abort.
3950 2012-09-04 Eli Zaretskii <eliz@gnu.org>
3952 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
3953 offsets[j].dv, since the y axis of the screen coordinates points
3954 down, while the y axis of the font definition coordinates points
3955 up. This fixes display of Arabic diacritics such as KASRA and
3956 KASRATAN. (Bug#11860)
3958 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3960 Be more systematic about _setjmp vs setjmp.
3961 * alloc.c (test_setjmp, mark_stack):
3962 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
3963 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
3964 (png_load, my_error_exit, jpeg_load):
3965 * process.c (send_process_trap, send_process):
3966 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
3967 The underscored versions are up to 30x faster on some hosts.
3968 Formerly, the code used setjmp+longjmp sometimes and
3969 _setjmp+_longjmp at other times, with no particular reason to
3970 prefer setjmp+longjmp.
3972 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
3974 Fix minor problem found by static checking.
3975 * buffer.c (Fdelete_all_overlays): Return nil.
3977 2012-09-03 Martin Rudalics <rudalics@gmx.at>
3979 * buffer.c (Fdelete_all_overlays): New function.
3981 2012-09-03 Chong Yidong <cyd@gnu.org>
3983 * gtkutil.c: Add extern decl for Qxft.
3985 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
3987 * emacs.c, eval.c: Use bool for boolean.
3988 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
3989 (malloc_using_checking) [DOUG_LEA_MALLOC]:
3990 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:

3995 (maybe_call_debugger, Fbacktrace):
3996 * process.c (read_process_output, exec_sentinel):
3997 Use bool for booleans.
3998 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
3999 All callers changed.
4000 * eval.c (interactive_p): Omit always-true boolean argument
4001 EXCLUDE_SUBRS_P. All callers changed.
4002 * dispextern.h, lisp.h: Reflect above API changes.
4003 * firstfile.c (dummy): Use the address of 'main', whose signature
4004 won't change, instead of the address of 'initialize', whose
4005 signature just changed from int to bool.
4006 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
4007 * msdos.c (fatal_error_in_progress): ... from here.
4008 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
4010 (redisplay_internal, unwind_redisplay): Simply clear
4011 REDISPLAYING_P when unwinding, instead of saving its previous,
4012 always-false value and then restoring it.
4014 Clean up some extern decls.
4015 Mostly, this hoists extern decls out of .c files and into .h files.
4016 That way, we're more likely to catch errors if the interfaces change.
4017 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
4018 declare xg_mark_data.
4019 * dispextern.h (x_frame_parm_handlers):
4021 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
4022 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
4023 (Qultra_bold, Qoblique, Qitalic):
4024 Move extern decl here from .c file.
4025 * alloc.c (xg_mark_data) [USE_GTK]:
4027 * eval.c (Qlexical_binding):
4028 * fns.c (time) [!HAVE_UNISTD_H]:

4037 * xfont.c (x_clear_errors):
4038 * xterm.c (x_frame_parm_handlers):
4039 Remove now-redundant extern decls.
4040 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
4041 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
4043 * xfaces.c: Remove unnecessary static decls.
4044 * xterm.c (updating_frame): Remove decl of nonexistent object.
4046 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
4047 when building globals.h, as the objects that are not built on
4048 this host are not needed to compile C files on this host.
4050 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
4052 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
4054 * frame.h: Add missing prototype for x_wm_set_size_hint.
4056 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

4104 offset adjustment values separately for each cluster. (Bug#11860)
4106 * image.c: Restore mistakenly removed inclusion of w32.h. Without
4107 it, GCC doesn't see prototypes of w32_delayed_load, and complains
4108 about implicit conversions from integer to pointer.

4166 window system declarations.
4168 * frame.h: Move common functions here: set_frame_menubar,
4169 x_set_window_size, x_sync, x_get_focus_frame,
4170 x_set_mouse_position, x_set_mouse_pixel_position,
4171 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

4201 the frames which are reachable from Vframe_list.
4202 * term.c (mark_ttys): Remove.
4203 (init_tty): Safely initialize 'top_frame' slot with Qnil.

4227 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
4228 for GCC 4.7.1 x86-64.
4230 2012-08-30 Glenn Morris <rgm@gnu.org>
4232 * lread.c (init_lread): For out-of-tree builds, only add the
4233 source directory's site-lisp dir to the load-path if it exists,
4234 consistent with in-tree builds. (Bug#12302)
4236 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

4257 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
4258 Add window_closed and button_values. Add void as return value for
4259 add(Button|String|Split). addButton takes int instead of Lisp_Object.

4470 It was meant to be temporary and it often doesn't work,
4471 because when IDX has side effects the behavior of IDX==IDX
4472 is undefined. See Stefan Monnier in
4473 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.

4489 All uses and decls removed.

4536 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
4537 since the 1-or-0 return value is always ignored anyway.
4538 (mmap_initialized_p):
4539 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
4540 * buffer.h, lisp.h: Adjust prototypes to match above changes.
4542 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
4544 * bidi.c: Use bool for boolean.
4545 This is a bit more readable, and makes the text segment of bidi.o
4546 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
4547 Presumably it's faster too.
4548 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
4550 (bidi_cache_find_level_change, bidi_cache_iterator_state)
4551 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
4552 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
4553 (bidi_explicit_dir_char, bidi_level_of_next_char)
4554 (bidi_find_other_level_edge, bidi_move_to_visually_next):
4555 Use bool for booleans, instead of int.
4556 * dispextern.h (bidi_init_it, bidi_paragraph_init)
4557 (bidi_unshelve_cache): Adjust decls to match code.
4559 2012-08-23 Martin Rudalics <rudalics@gmx.at>
4561 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
4564 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
4566 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
4567 * atimer.h: Include <stdbool.h>.
4569 2012-08-22 Dan Nicolaescu <dann@gnu.org>
4571 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
4572 compile time tests instead of run time tests on systems that do
4574 (FRAME_MAC_P): Remove leftover from deleted code.
4575 * frame.c (syms_of_frame): Remove leftover from deleted code.
4577 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
4579 * nsterm.m (insertText:): Don't clear modifiers if code is space.
4581 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
4583 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
4584 Otherwise, the compiler complains about (A?B:C) where B is void
4585 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
4586 (fontset_add): Return void, for FONTSET_ADD.
4588 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4590 * alloc.c: Use bool for booleans.
4591 (gc_in_progress, abort_on_gc)
4592 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
4593 (dont_register_blocks) [GC_MALLOC_CHECK]:
4594 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
4595 (check_string_bytes, make_specified_string, memory_full)
4596 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
4597 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
4598 (mark_stack, valid_pointer_p, make_pure_string)
4599 (Fgarbage_collect, survives_gc_p, gc_sweep):
4600 Use bool for booleans, instead of int.
4601 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
4602 Remove unused local.
4603 * alloc.c (PURE_POINTER_P):
4604 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
4605 * editfns.c (Fformat):
4606 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
4608 * fns.c (sweep_weak_table):
4609 * lisp.h (suppress_checking, push_message, survives_gc_p)
4610 (make_pure_string, gc_in_progress, abort_on_gc):
4611 * lread.c (readchar, read1):
4612 * print.c (Fprin1_to_string):
4613 * xdisp.c (push_message):
4614 Use bool for booleans affected directly or indirectly by
4617 Make recently-introduced setters macros.
4618 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
4619 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
4620 (set_fontset_default, set_fontset_fallback): Rename from their
4621 upper-case counterparts, and make them functions rather than macros.
4622 This is more consistent with the other recently-introduced setters.
4623 These don't need to be inline, since they're local.
4625 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
4627 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
4628 the loop (Bug#12247).
4630 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4632 * lisp.h (vcopy): Use memcpy rather than our own loop.
4633 This fixes a performance regression introduced by the recent
4634 addition of vcopy. This means 'vcopy' will need to be modified
4635 for a copying collector, but that's OK. Also, tighten the
4636 checking in the assertion.
4638 2012-08-21 Eli Zaretskii <eliz@gnu.org>
4640 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
4641 components for RTL text (Bug#11860). Adjust X-OFFSET of each
4642 non-base glyph for the width of the base character, according to
4643 what x_draw_composite_glyph_string_foreground expects.
4644 Generate WADJUST value according to composition_gstring_width's
4645 expectations, to produce correct width of the composed character.
4646 Reverse the sign of the DU offset produced by ScriptPlace.
4648 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4650 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
4652 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
4654 Avoid direct writes to contents member of struct Lisp_Vector.
4655 * lisp.h (vcopy): New function to copy data into vector.
4656 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
4657 * fns.c (Ffillarray): Use ASET.
4658 * keyboard.c (timer_check_2): Use AREF and ASET.
4659 (append_tool_bar_item, Frecent_keys): Use vcopy.
4660 * lread.c (read_vector): Use ASET.
4661 * msdos.c (Frecent_doskeys): Use vcopy.
4662 * xface.c (Finternal_copy_lisp_face): Use vcopy.
4663 (Finternal_merge_in_global_face): Use ASET and vcopy.
4664 * xfont.c (xfont_list_pattern): Likewise.
4666 2012-08-21 Martin Rudalics <rudalics@gmx.at>
4668 * window.c (Fwindow_point): For the selected window always return
4669 the position of its buffer's point.
4670 (Fset_window_point): For the selected window always go in its
4671 buffer to the specified position.
4673 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
4675 Setter macros for fontsets.
4676 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
4677 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
4678 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
4681 2012-08-20 Glenn Morris <rgm@gnu.org>
4683 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
4684 Don't assume that `ln -f' works.
4686 2012-08-20 Eli Zaretskii <eliz@gnu.org>
4688 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
4689 and later about non-assignments with no effect. See discussion at
4690 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
4693 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
4695 Inline setter functions for Lisp_Objects slots of struct specbinding.
4696 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
4699 2012-08-20 Martin Rudalics <rudalics@gmx.at>
4701 * window.c (select_window): Always make selected window's buffer
4704 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
4706 Use AREF and ASET for docstrings of category tables.
4707 * category.h (CATEGORY_DOCSTRING): Use AREF.
4708 (SET_CATEGORY_DOCSTRING): Use ASET.
4709 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
4711 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
4713 Inline setter functions for hash table members.
4714 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
4715 (set_hash_hash, set_hash_index): Rename with _slot suffix.
4716 (set_hash_key_and_value, set_hash_index, set_hash_next)
4717 (set_hash_hash): New functions.
4718 * charset.c, fns.c: Adjust users.
4720 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
4722 Inline getter and setter functions for per-buffer values.
4723 * buffer.h (per_buffer_default, set_per_buffer_default)
4724 (per_buffer_value, set_per_buffer_value): New functions.
4725 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
4726 * buffer.c, data.c: Adjust users.
4728 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
4730 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
4732 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
4734 Rely on <config.h> + <unistd.h> to declare 'environ',
4735 as gnulib does this if the system doesn't.
4736 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
4737 Remove declaration. MS-Windows declares it on stdlib.h which is
4738 included by conf_post.h.
4739 * emacs.c (environ) [DOUG_LEA_MALLOC]:
4740 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
4741 * vm-limit.c: Include <unistd.h>, for 'environ'.
4743 * unexaix.c, unexcoff.c: Include "mem-limits.h".
4744 (start_of_data): Remove decl; mem-limits.h provides it.
4746 * xdisp.c (handle_invisible_prop): Make it a bit faster
4747 and avoid a gcc -Wmaybe-uninitialized diagnostic.
4749 2012-08-19 Chong Yidong <cyd@gnu.org>
4751 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
4754 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
4756 * .gdbinit: Use call instead of set when calling a function in the
4759 * data.c (set_internal): Don't use set_blv_found.
4760 (Fkill_local_variable): Likewise.
4762 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
4764 * nsfont.m (ns_ascii_average_width): Ensure the string
4765 ascii_printable is initialized with a null-terminated character
4766 array. Otherwise, it can contain undesired extra characters.
4768 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
4770 port new setting code to Sun C 5.8 2005/10/13
4771 * chartab.c, lisp.h (char_table_set, char_table_set_range):
4772 Return void, not Lisp_Object. Otherwise, the compiler
4773 complains about (A?B:C) where B is void and C is Lisp_Object
4774 when compiling CHAR_TABLE_SET, due to the recent change to
4775 the API of sub_char_table_set_contents.
4777 2012-08-18 Chong Yidong <cyd@gnu.org>
4779 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
4780 for the string case (Bug#3874).
4782 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
4784 * buffer.h (BSET): Remove (Bug#12215).

4863 are compiled into code.
4864 (tset_param_alist): New setter function.
4866 2012-08-17 Paul Eggert <eggert@cs.ucla.edu>

4901 A few more naming-convention fixes for getters and setters.
4902 * buffer.c (set_buffer_overlays_before): Move here from buffer.h,
4903 and rename from buffer_overlays_set_before.
4904 (set_buffer_overlays_after): Move here from buffer.h, and rename
4905 from buffer_overlays_set_after.
4906 * buffer.h (buffer_intervals): Rename from buffer_get_intervals.

4933 "CSET (XCHAR_TABLE (char_table), parent, parent);" with
4934 "set_char_table_parent (char_table, parent);".
4935 The old version was confusing because it used the same name
4936 'parent' for two different things.
4938 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>
4940 Functions to get and set Lisp_Object fields of buffer-local variables.

4946 2012-08-17 Chong Yidong <cyd@gnu.org>
4948 * xfaces.c (merge_face_vectors): If the target font specfies a
4949 font spec, make the font's attributes take precedence over
4950 directly-specified attributes.
4951 (merge_face_ref): Recognize :font.
4953 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>
4955 Do not use memcpy for copying intervals.
4956 * intervals.c (reproduce_interval): New function.

5608 * w32.c (init_environment): Change the default values of many
5609 environment variables in dflt_envvars[] to NULL, to avoid pushing
5610 them into environment when they were not already defined.
5611 Remove the code that deletes site-lisp subdirectories from the default
5612 value of EMACSLOADPATH, as it is no longer needed.
5613 (check_windows_init_file): Now external, not static.
5614 Use Vload_path as is, without adding anything, as this function is now
5615 called when Vload_path is already set up.
5617 * w32.h (check_windows_init_file): Add prototype.
5619 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

5626 installation tree, as appropriate.
5628 * callproc.c (init_callproc_1): Call decode_env_path instead of
5629 doing its equivalent by hand.

5662 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
5663 Remove unnecessary pointer casts.
5664 * alloc.c (record_xmalloc): New function.
5665 * lisp.h (record_xmalloc): New decl.
5666 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
5667 more like a function. This is because the pointer cast is not
5668 needed. All uses changed.
5669 * print.c (print_string, print_error_message): Avoid length recalc.
5671 Improve fix for macroexp crash with debugging (Bug#12118).
5672 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
5673 ARRAY_MARK_FLAG when checking subscripts, because ASET is
5674 not supposed to be invoked from the garbage collector.

5676 (gc_aset): New function, which is like ASET but can be
5677 used in the garbage collector.

5706 with addition of handling of symlinks and support for 'lstat'.
5707 If possible, get file's attributes and security information by
5708 handle, not by name. Produce S_IFLNK bit for symlinks, when
5709 called from 'lstat'.
5710 (stat, lstat): New functions, call 'stat_worker'.
5711 (symlink, readlink, careadlinkat): Rewritten to create and resolve
5712 symlinks when the underlying filesystem supports them.
5714 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
5716 Fix macroexp crash on Windows with debugging (Bug#12118).
5717 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
5718 checking subscripts; problem introduced with the recent
5719 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
5720 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
5721 since it's used in non-static inline functions now.
5723 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
5724 Don't assume buffer size fits in 'int'. Remove unused local.

5744 * composite.c (COMPOSITE_INLINE):
5745 * dispnew.c (DISPEXTERN_INLINE):
5746 * sysdep.c (SYSTIME_INLINE):
5747 Define to EXTERN_INLINE, so that the corresponding functions
5748 are compiled into code.
5749 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
5750 (INLINE_HEADER_END): New macros.
5751 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

5771 hard-coding the path separator.
5773 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
5775 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
5776 This how ASET and AREF are supposed to work, and makes
5777 it easier to think about future improvements. See
5778 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
5779 * charset.h (set_charset_attr): New function.

6271 the fix for 12036 would have avoided some of the problems noted in

6294 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
6295 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
6296 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
6297 Adjust to changes in lisp.h and emacs.c, by using
6298 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
6299 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
6300 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
6301 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
6302 instead of gdb_valbits.
6303 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
6304 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
6305 instead of gdb_array_mark_flag.
6306 (xboolvector): Get size from $->size, not $->header.size.
6307 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
6308 (xreload, hook-run, hookpost-run): Remove.
6309 * emacs.c: Include <verify.h>.
6310 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
6311 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
6313 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
6314 (gdb_USE_LSB_TAG): New enum constants.
6315 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

6317 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
6318 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
6319 as constants, so they're visible to GDB.

6321 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
6322 Now enum constants, not macros, so they're visible to GDB.
6323 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
6324 more convenient now. All uses changed.
6325 (VALMASK) [USE_LSB_TAG]: Also define in this case.

6338 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
6340 Use typedef for EMACS_INT, EMACS_UINT.
6341 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
6342 than macros. This simplifies debugging in the usual case, since
6343 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
6344 and it allows expressions involving EMACS_INT casts.
6345 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
6347 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

6363 (init_buffer_once): Initialize indirection counters of
6364 buffer_defaults and buffer_local_symbols (for sanity and safety).
6366 2012-07-24 Eli Zaretskii <eliz@gnu.org>

6399 Swap buffer text indirection counters in Fbuffer_swap_text.
6400 * buffer.c (Fbuffer_swap_text): Swap indirections too.
6401 This avoids crash reported by Christoph Scholtes at
6402 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
6404 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
6406 * nsmenu.m (Popdown_data): New struct.

6429 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
6431 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
6432 as it's limited by the amount of memory, not by INT_MAX.
6434 2012-07-21 Eli Zaretskii <eliz@gnu.org>
6436 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
6437 in special-event-map. See the discussion at

7210 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
7211 * nsterm.m (ns_term_init):
7212 Avoid the need for strncpy, by using build_string or
7213 make_unibyte_string directly. Use dtoastr, not snprintf.
7214 * process.c (Fmake_network_process): Diagnose service names that
7215 are too long, rather than silently truncating them or creating
7216 non-null-terminated names.
7217 (Fnetwork_interface_info): Likewise, for interface names.
7218 * sysdep.c (system_process_attributes) [GNU_LINUX]:
7219 Prefer sprintf to strncat.
7220 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:

7246 Optimize pure C strings initialization.
7247 * lisp.h (make_pure_string): Fix prototype.
7248 (build_pure_c_string): New function, defined as static inline. This
7249 provides a better opportunity to optimize away calls to strlen when
7250 the function is called with compile-time constant argument.
7251 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
7252 argument, adjust users accordingly. Use build_pure_c_string where
7254 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
7255 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
7256 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
7258 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
7260 Avoid calls to strlen in miscellaneous functions.
7261 * buffer.c (init_buffer): Use precalculated len, adjust if needed.

7273 Adjust users accordingly.
7274 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
7276 2012-07-10 Glenn Morris <rgm@gnu.org>

7283 * s/gnu.h (DATA_START): Move definitions to configure.
7285 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
7286 We include usg5-4-common.h, which defines them both.
7288 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
7289 O_RDONLY already includes it).
7291 Stop ns builds setting the EMACSLOADPATH environment variable.
7292 * nsterm.m (ns_load_path): Rename from ns_init_paths.
7293 Now it does not set EMACSLOADPATH, just returns the load-path string.
7294 * nsterm.h: Update accordingly.
7295 * lread.c [HAVE_NS]: Include nsterm.h.
7296 (init_lread) [HAVE_NS]: Use ns_load_path.

7299 2012-07-09 Glenn Morris <rgm@gnu.org>
7301 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
7302 since the included bsd-common.h does so.
7304 Stop ns builds setting the EMACSPATH environment variable.
7305 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
7306 (ns_init_paths): Do not set EMACSPATH.
7307 * nsterm.h (ns_exec_path): Add it.
7308 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
7311 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
7313 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
7315 * process.c (wait_reading_process_output): 'waitchannels' was unset
7316 when read_kbd || !NILP (wait_for_cell); fix this.
7318 Add GCC-style 'const' attribute to functions that can use it.
7319 * character.h (char_resolve_modifier_mask):
7320 * keyboard.h (make_ctrl_char):
7321 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

7330 Add decls with ATTRIBUTE_CONST.
7332 Minor improvements to make_formatted_string.
7333 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
7334 where int is good enough, as vsprintf returns an int.
7335 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
7337 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7339 Use make_formatted_string to avoid double length calculation.

7364 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7366 Move marker debugging code under MARKER_DEBUG.
7367 * marker.c (MARKER_DEBUG): Move marker debugging code under
7368 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
7369 for bootstrap with --enable-checking (~3x slowdown reported
7370 by Juanma Barranquero <lekktu@gmail.com>).
7371 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
7373 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
7375 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
7376 See <http://bugs.gnu.org/11825#29>.
7378 2012-07-08 Eli Zaretskii <eliz@gnu.org>
7380 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
7381 has no font, use the frame's font. (Bug#11813)
7382 (display_line): Add commentary about displaying truncation glyphs
7384 (produce_special_glyphs): Move here from term.c.
7386 * term.c (produce_special_glyphs): Move to xdisp.c.
7388 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
7391 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
7393 * xdisp.c (display_line): Avoid warning about implicit declaration
7396 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
7398 * lisp.h: Remove empty conditional.
7400 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
7402 * lread.c (load_path_check): Now static.
7404 Fix some minor --with-ns problems found by static checking.
7405 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
7406 (x_set_font) [!HAVE_X_WINDOWS]:
7407 * image.c (xpm_load_image) [HAVE_NS]:
7408 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
7409 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
7410 Remove unused local.
7411 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
7412 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
7413 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
7414 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
7415 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
7416 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:

7419 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
7421 2012-07-07 Glenn Morris <rgm@gnu.org>
7423 * lread.c (load_path_check): New function, split from init_lread.
7424 (init_lread): Reorganize. Motivation:
7425 If EMACSLOADPATH is set, check/warn about that rather than the
7426 defaults, which we are not going to use. Hence we can remove
7427 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
7428 Don't warn if site-lisp directories are missing.
7429 If not installed, start from a blank load-path, since
7430 PATH_LOADSEARCH refers to the eventual installation directories.
7432 2012-07-07 Eli Zaretskii <eliz@gnu.org>
7434 Support truncation and continuation glyphs on GUI frames, when
7435 fringes are disabled. (Bug#11832)
7436 * xdisp.c (init_iterator): Get dimensions of truncation and
7437 continuation glyphs even if on GUI frames.
7438 Adjust it->last_visible_x on GUI frames when the left or right fringes,
7439 or both, are absent.
7440 (start_display, move_it_in_display_line_to): Handle the case of a
7441 GUI frame without a fringe to display continuation or truncation
7443 (insert_left_trunc_glyphs): Support GUI frames: make sure
7444 truncation glyphs overwrite enough glyphs from the current line to
7445 have sufficient space in pixels.
7446 (display_line): Support truncation and continuation glyphs on GUI
7447 frames. If some spare pixels are left on the line after inserting
7448 the truncation glyphs, fill that space with a stretch glyph of a
7449 suitably computed width.
7451 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
7452 produce_glyphs, to support GUI sessions.
7454 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
7456 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
7458 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
7460 Do not require float-time's arg to fit in time_t (Bug#11825).
7461 This works better on hosts where time_t is unsigned, and where
7462 float-time is applied to the (negative) difference between two times.
7463 * editfns.c (decode_time_components): Last arg is now double *,
7464 not int *, and means to store all the result as a double, without
7465 worrying about whether the seconds part fits in time_t.
7466 All callers changed.
7467 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
7468 All callers changed.
7469 (Ffloat_time): Do not fail merely because the specified time falls
7470 outside of time_t range.
7472 2012-07-07 Glenn Morris <rgm@gnu.org>
7474 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
7475 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):

7478 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
7480 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
7481 Update dependencies.
7483 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
7485 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7487 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

7489 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
7490 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
7491 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.

7494 * xfont.c (compare_font_names): Redo to omit the need for casts.
7496 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
7498 * xfns.c (Fx_change_window_property): Doc fix.
7499 * w32fns.c (Fx_change_window_property): Doc fix.
7501 * w32fns.c (Fx_window_property): Accept the same arguments as the
7502 X Windows version. Doc fix.
7503 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
7505 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
7506 Eli Zaretskii <eliz@gnu.org>
7508 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
7509 Windows-specific code from nt/config.nt moved here.
7510 Obsolete settings removed.
7512 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7514 * process.c: Avoid unnecessary calls to gettime.
7515 (wait_reading_process_output): Don't get the time of day
7516 when gobbling data immediately and not waiting, as there's no need
7517 for it in that case. This removes a FIXME.
7519 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
7521 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
7522 is defined (Bug#11768).
7524 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7526 Fix marker debugging code.
7527 * marker.c (byte_char_debug_check): Do not perform the check
7528 if buffer is not multibyte.
7529 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
7530 Call byte_char_debug_check with correct arguments.
7532 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7534 Compile marker debugging code only if ENABLE_CHECKING is defined.
7535 * marker.c (byte_char_debug_check, count_markers):
7536 Use only if ENABLE_CHECKING is defined.
7537 (byte_debug_flag): Remove.
7538 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
7539 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
7541 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7543 Avoid code repetition in marker-related functions.
7544 * marker.c (attach_marker): New function.
7545 (Fset_marker, set_marker_restricted, set_marker_both)
7546 (set_marker_restricted_both): Use it.
7547 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
7548 Consistently rename charno to charpos.
7549 (marker_position): Add eassert.
7550 (marker_byte_position): Convert to eassert.

7569 * window.c (save_window_save): Likewise.
7571 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7573 Do not use Fdelete_overlay in delete_all_overlays
7574 to avoid redundant calls to unchain_overlay.
7575 * buffer.c (drop_overlay): New function.
7576 (delete_all_overlays, Fdelete_overlay): Use it.
7577 * minibuf.c (get_minibuffer): Fix comment.
7579 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7581 Port to OpenBSD 5.1 amd64.
7582 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
7583 This is needed for OpenBSD, and should be harmless on all BSD systems.
7584 Also, include <sys/sysctl.h>, as it should be available on all
7585 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
7586 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
7587 use p_pid member, not kp_proc.pid.
7589 2012-07-06 Glenn Morris <rgm@gnu.org>
7591 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
7593 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
7595 More xmalloc and related cleanup.
7596 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
7597 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
7598 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:
7599 * font.c, fontset.c, frame.c, fringe.c, ftfont.c, ftxfont.c, gmalloc.c:
7600 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:
7601 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:
7602 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
7603 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
7604 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
7606 Omit needless casts involving void * pointers and allocation.
7607 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
7608 as the former is more robust if P's type is changed.
7609 Prefer xzalloc to xmalloc + memset 0.
7610 Simplify malloc-or-realloc to realloc.
7611 Don't worry about xmalloc returning a null pointer.
7612 Prefer xstrdup to xmalloc + strcpy.
7613 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
7615 * keyboard.c (apply_modifiers_uncached): Prefer local array to
7616 alloca of a constant.
7618 2012-07-05 Eli Zaretskii <eliz@gnu.org>
7620 * xdisp.c (display_line): Fix horizontal pixel coordinates when
7621 hscroll is larger than the line width. Fixes long and futile
7622 looping inside extend_face_to_end_of_line (on a TTY) producing
7623 glyphs that are not needed and thrown away.
7625 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
7627 * marker.c (set_marker_restricted_both): Simplify by using

7637 not defined (Bug#11768).
7638 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
7639 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
7640 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
7641 followed by gtk_box_set_homogeneous (Bug#11768).
7642 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
7643 (update_theme_scrollbar_width, xg_create_scroll_bar):
7644 Use gtk_scrollbar_new (Bug#11768).
7645 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.

7653 * xdisp.c (window_hscroll_limited): New function.
7654 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
7655 coordinates when window's hscroll is set to insanely large
7658 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
7660 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
7661 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
7663 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
7666 * lisp.h (xzalloc): New prototype. Omit needless casts.
7667 * alloc.c (xzalloc): New function. Omit needless casts.

7721 * fileio.c (time_error_value): Check the right error number.
7722 Problem reported by Troels Nielsen in
7723 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
7725 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7727 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
7728 This should be fixed in a better way; see Eli Zaretskii in
7729 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
7730 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
7732 * fileio.c (time_error_value): Rename from special_mtime.
7733 The old name's problems were noted by Eli Zaretskii in
7734 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
7736 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
7737 This variable's comment says Emacs needs at least one GDB-visible
7738 symbol of type enum pvec_type, to work around GDB problems.
7739 The symbol's value doesn't matter.
7741 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
7742 that causes compilation to fail on pre-C99 compilers.
7744 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
7746 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
7747 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
7749 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
7751 * buffer.c (init_buffer_once): Fix initialization of
7752 headers for buffer_defaults and buffer_local_symbols.
7753 Reported by Juanma Barranquero <lekktu@gmail.com>.
7755 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
7757 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
7758 * lisp.h (enum pvec_type): Use fewer bits.
7759 (PSEUDOVECTOR_SIZE_BITS): New constant.
7760 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
7761 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
7762 change in pvec_type.
7763 (PSEUDOVECTOR_TYPEP): New macro.
7764 (TYPED_PSEUDOVECTORP): Use it.
7765 * fns.c (internal_equal): Adapt code to extract pvectype.

7767 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
7768 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
7769 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
7770 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
7771 (sweep_vectors): Use it. Use local var `total_bytes' instead of
7772 abusing vector->header.next.nbytes.
7773 (live_vector_p): Use PVEC_TYPE.
7774 (mark_object): Adapt code to extract pvectype. Use switch.
7776 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7778 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
7779 Tighten new eassert a bit.
7781 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
7783 Fix compilation with --enable-gcc-warnings and -O1
7785 * doprnt.c (doprnt): Change type of tem to int, initialize
7786 to avoid compiler warning. Add eassert.
7787 * search.c (simple_search): Initialize match_byte to avoid
7788 compiler warning. Add eassert.
7790 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7792 Avoid weird behavior with large horizontal scrolls.
7793 Without this change, for example, large hscroll values would
7794 mess up Emacs's display on Fedora 15 x86, presumably due to
7795 overflows in int calculations in the display code.
7796 Also, if buffers had long lines, Emacs would freeze.
7797 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
7798 (set_window_hscroll): New function, containing the old guts of
7799 Fset_window_hscroll. Return the clipped value.
7800 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
7801 This avoids the need to check against PTRDIFF_MAX.
7803 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
7805 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
7807 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
7809 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7811 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
7812 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
7813 since GCC 4.4.6 issues a bogus warning for them.
7815 Fix bugs in file timestamp newness comparisons.
7816 * fileio.c (Ffile_newer_than_file_p):
7817 * lread.c (Fload): Use full timestamp resolution of files,
7818 not just the 1-second resolution, so that files that are only
7819 slightly newer still count as newer.
7820 * fileio.c (Ffile_newer_than_file_p): Don't assume file
7821 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
7823 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
7825 * fileio.c: Improve handling of file time marker. (Bug#11852)
7826 (special_mtime): New function.
7827 (Finsert_file_contents, Fverify_visited_file_modtime):
7828 Use it to set special mtime values consistently.
7830 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
7832 * fileio.c (Finsert_file_contents): Properly handle st_mtime
7833 marker for non-existing file. (Bug#11852)
7835 2012-07-03 Glenn Morris <rgm@gnu.org>
7837 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
7838 and did not make it into globals.h).
7840 2012-07-03 Tom Tromey <tromey@redhat.com>
7842 * window.c (Fset_window_margins, Fset_window_fringes)
7843 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
7844 * textprop.c (Fprevious_property_change): No longer static.
7845 * syntax.c (Fsyntax_table_p): No longer static.

7867 * intervals.h: Remove EXFUNs.
7868 * fontset.h: Remove EXFUN.

7873 * w32term.h: Remove EXFUNs.
7874 * window.h: Remove EXFUNs.

7876 * xterm.h: Remove EXFUN.
7878 2012-07-03 Glenn Morris <rgm@gnu.org>
7880 * lisp.h (Frandom): Make it visible to C.
7881 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
7882 buffer for invisible buffers. (Bug#1229)
7884 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7886 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
7887 values which aren't power of 2.
7888 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
7889 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
7892 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
7894 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
7896 * alloc.c (mark_object): Revert part of last patch to use `switch'.
7898 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7900 * alloc.c (allocate_vector_block): Remove redundant
7901 calls to mallopt if DOUG_LEA_MALLOC is defined.
7902 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
7903 avoid calls to mallopt if zero_vector is returned.
7905 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7907 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
7908 is enabled, avoid dereferencing NULL current_sblock if
7911 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7913 Cleanup basic buffer management.
7914 * buffer.h (struct buffer): Change layout to use generic vector
7915 marking code. Fix some comments. Change type of 'clip_changed'
7916 to bitfield. Remove unused #ifndef old.
7917 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
7918 (GET_OVERLAYS_AT): Fix indentation.
7919 (for_each_per_buffer_object_at): New macro.

7923 * alloc.c (allocate_buffer): Adjust to match new layout of
7924 struct buffer. Fix comment.
7925 (mark_overlay): New function.

7928 (mark_object): Use it. Adjust marking of misc objects
7929 and related comments.
7931 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
7933 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
7934 wrapper that is not needed because the wrapped code is a no-op (zero
7935 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
7936 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
7938 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
7940 * alloc.c (mark_buffer): Simplify. Remove prototype.
7941 (mark_object): Add comment. Reorganize marking of vector-like
7942 objects. Use CHECK_LIVE for all vector-like objects except buffers
7943 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
7944 Avoid redundant calls to mark_vectorlike for bool vectors.
7946 2012-06-30 Glenn Morris <rgm@gnu.org>
7948 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
7950 * epaths.in (PATH_SITELOADSEARCH): New.
7951 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
7952 This is rather than relying on --enable-locallisppath elements
7953 having "site-lisp" in their names. (Bug#10208#25, 11658)
7955 2012-06-30 Eli Zaretskii <eliz@gnu.org>
7957 * w32proc.c (sys_select): Accept and ignore one more argument.
7959 * w32.c (emacs_gnutls_pull): Call select with one more argument.
7961 * sysselect.h [DOS_NT]: Don't include sys/select.h.
7962 (pselect) [!MS_DOS]: Redirect to sys_select.
7964 * sysdep.c: Don't include dos.h and dosfns.h.
7966 * process.c (sys_select):
7967 * msdos.c (sys_select): Accept one more argument and ignore it.
7969 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
7970 adapt data types and code to that.
7973 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
7974 which clashes with the gnulib function of the same name.
7976 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
7978 * font.c (font_style_to_value, font_style_symbolic)
7979 (font_prop_validate_style): Add type checks for values in
7982 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
7984 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
7987 2012-06-29 Eli Zaretskii <eliz@gnu.org>
7989 * xdisp.c (try_window_id): Undo last change.
7991 * w32.c (getwd): Adjust commentary about startup_dir.
7992 (init_environment): Always call sys_access, even in non-MSVC
7993 builds. Don't chdir to the directory of the Emacs executable.
7994 This undoes code from 1997 which was justified by the need to
7995 "avoid conflicts when removing and renaming directories". But its
7996 downside was that every relative file name was being interpreted
7997 relative to the directory of the Emacs executable, which can never
7998 be TRT. In particular, it broke sys_access when called with
7999 relative file names.
8000 (sys_access): Map GetLastError to errno.
8002 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8004 * window.h (struct window): Change type of 'fringes_outside_margins'

8006 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
8008 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
8011 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
8013 * gnutls.c (emacs_gnutls_handshake):
8014 Add QUIT to make the loop interruptible.
8016 2012-06-29 Glenn Morris <rgm@gnu.org>
8018 * charset.c (init_charset): Make lack of etc/charsets fatal.
8020 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8022 * editfns.c (region_limit): Fix type mismatch.
8024 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8026 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
8027 undefined. Convert from xassert to eassert.
8028 * nsmenu.m: Convert from xassert to eassert.
8029 * nsterm.m: Likewise.
8031 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
8033 * editfns.c (region_limit): Clip to narrowing (bug#11770).
8035 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
8037 Avoid integer overflow on scroll-left and scroll-right.
8038 * window.c (HSCROLL_MAX): New macro.
8039 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
8040 overflow when requested scroll falls outside ptrdiff_t range.
8042 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8044 * window.h (struct window): Change type of 'hscroll',
8045 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
8046 'last_modified' and 'last_overlay_modified' to EMACS_INT.
8047 Adjust users accordingly.
8048 * xdisp.c (try_cursor_movement): Replace type check with eassert.
8049 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
8050 from EMACS_INT to ptrdiff_t.
8051 (make_window): Omit redundant initialization.
8053 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
8055 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
8057 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8059 * window.h (struct window): Change type of 'use_time' and
8060 'sequence_number' from Lisp_Object to int.

8069 enabled with --enable-checking=[all,glyphs] configure option.
8070 Fix GLYPH_DEBUG usage assuming that it may be undefined,
8071 adjust comments accordingly.

8189 * w32proc.c (sys_spawnve): Likewise.
8190 * xterm.c (x_term_init): Likewise.
8192 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
8194 Use sprintf return value instead of invoking strlen on result.
8195 In the old days this wasn't portable, since some sprintf
8196 implementations returned char *. But they died out years ago and
8197 Emacs already assumes sprintf returns int.
8198 Similarly for float_to_string.
8199 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
8200 * ccl.c (ccl_driver):
8201 * character.c (string_escape_byte8):

8204 * print.c (print_object):
8205 * xdisp.c (message_dolog):
8206 * xfns.c (syms_of_xfns):
8207 Use sprintf or float_to_string result to avoid need to call strlen.
8208 * data.c (Fnumber_to_string):
8209 Use make_unibyte_string, since the string must be ASCII.
8210 * lisp.h, print.c (float_to_string): Now returns int length.
8211 * term.c (produce_glyphless_glyph):
8212 Use sprintf result rather than recomputing it.
8214 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
8215 * Makefile.in (ALL_CFLAGS):
8216 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
8217 * gmalloc.c, regex.c: Include <config.h> unconditionally.

8238 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
8240 * gtkutil.c (get_utf8_string): Remove redundant assignment.
8241 sprintf already null-terminates its output.
8243 * xfns.c (x_window): Remove redundant cast.
8245 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
8247 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
8248 `const char *' to `char *' to avoid compiler warning.
8250 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
8252 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
8253 instead of truncating it to 63 (admittedly a generous limit).
8255 * process.c: Fix spelling and caps in comments.
8257 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
8259 * emacs.c (setpgrp): Remove definition, unused.

8306 Remove unnecessary forward decls.
8308 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
8310 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
8311 * lisp.h (WAIT_READING_MAX): New macro.
8312 * dispnew.c (Fsleep_for, sit_for):
8313 * keyboard.c (kbd_buffer_get_event):
8314 * process.c (Faccept_process_output):
8315 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
8316 This improves on the previous patch, which introduced a bug
8317 when time_t is unsigned and as wide as intmax_t.
8318 See <http://bugs.gnu.org/9000#51>.
8320 2012-06-23 Eli Zaretskii <eliz@gnu.org>
8322 * dispnew.c (sit_for, Fsleep_for):
8323 * keyboard.c (kbd_buffer_get_event):

8336 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
8337 Privately reported by Herbert J. Skuhra.
8338 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
8340 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
8341 not make_lisp_timeval, when the argument is of type EMACS_TIME.
8343 2012-06-23 Eli Zaretskii <eliz@gnu.org>
8345 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
8346 last argument of make_unibyte_string.
8348 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
8349 language ID in the event parameters.
8351 * w32term.c (w32_read_socket): Put the new keyboard codepage into
8352 event.code, not the obscure "character set ID".

8375 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
8376 Privately reported by Herbert J. Skuhra.

8383 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
8385 Support higher-resolution time stamps (Bug#9000).
8386 The time stamps are only nanosecond-resolution at the C level,
8387 since that's the best that any real-world system supports now.
8388 But they are picosecond-resolution at the Lisp level, as that's
8389 easy, and leaves room for future OS improvements.
8391 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
8394 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
8395 Don't get current time unless it's needed.
8397 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
8398 now provides it if it's absent.
8399 (start_atimer): Port to higher-res time stamps.
8400 Check for time stamp overflow. Don't get current time more
8401 often than is needed.
8403 * buffer.h (struct buffer): Buffer modtime now has high resolution.
8404 Include systime.h, not time.h.
8405 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
8407 * dired.c: Include stat-time.h.
8408 (Ffile-attributes): File times now have higher resolution.
8410 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
8411 (struct image): Timestamp now has higher resolution.
8413 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
8414 has at least microseconds now. All uses removed.
8415 (update_frame, update_single_window, update_window, update_frame_1)
8416 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
8417 (duration_to_sec_usec): Remove; no longer needed.
8419 * editfns.c (time_overflow): Now extern.
8420 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
8421 (float-time, Fformat_time_string, Fcurrent_time_string)

8425 (decode_time_components, lisp_seconds_argument): New functions.
8426 (make_time): Now static.
8427 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
8428 Report an error if the time is invalid, rather than having the caller
8431 * fileio.c: Include <stat-time.h>
8432 (Fcopy_file): Copy higher-resolution time stamps.
8433 Prefer to set the time stamp via a file descriptor if that works.

8435 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
8436 (Fvisited_file_modtime, Fset_visited_file_modtime):
8437 Support higher-resolution time stamps.
8439 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
8441 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
8443 * image.c (prepare_image_for_display, clear_image_cache)
8444 (lookup_image): Port to higer-resolution time stamps.
8446 * keyboard.c (start_polling, bind_polling_period):
8447 Check for time stamp overflow.
8448 (read_char, kbd_buffer_get_event, timer_start_idle)
8449 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
8450 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
8451 Port to higher-resolution time stamps. Do not assume time_t is signed.
8452 (decode_timer): New function. Timers are now vectors of length 9,
8453 not 8, to accommodate the picosecond component.
8454 (timer_check_2): Use it.
8456 * nsterm.m (select_timeout, timeval_subtract): Remove.
8457 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
8458 as they're a bit more accurate and handle overflow better.
8459 (ns_select): Change prototype to be compatible with pselect.
8460 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
8461 * nsterm.h (ns_select): Adjust prototype.
8463 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
8464 us-resolution time stamps.
8465 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
8467 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
8469 * lisp.h (time_overflow): New decl.
8470 (wait_reading_process_output): First arg is now intmax_t, not int,
8471 to accommodate larger waits.
8473 * process.h (struct Lisp_Process.read_output_delay):
8474 Now counts nanoseconds, not microseconds.
8475 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
8477 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
8478 (wait_reading_process_output):
8479 Port to ns-resolution time stamps.
8480 (Faccept_process_output, wait_reading_process_output):
8481 Check for time stamp overflow. Do not assume time_t is signed.
8482 (select_wrapper): Remove; we now use pselect.
8483 (Fprocess_attributes): Now generates ns-resolution time stamps.
8485 * sysdep.c: Include utimens.h. Don't include utime.h
8486 or worry about struct utimbuf; gnulib does that for us now.
8487 (gettimeofday): Remove; gnulib provides a substitute.
8488 (make_timeval): New function.
8489 (set_file_times): Now sets ns-resolution time stamps.
8490 New arg FD; all uses changed.
8491 (time_from_jiffies, ltime_from_jiffies, get_up_time)
8492 (system_process_attributes):
8493 Now returns ns-resolution time stamp. All uses changed.
8494 Check for time stamp overflow.
8496 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
8497 provides a substitute now.
8499 * systime.h: Include timespec.h rather than sys/time.h and time.h,
8500 since it guarantees struct timespec.
8501 (EMACS_TIME): Now struct timespec, so that we can support
8502 ns-resolution time stamps.
8503 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
8504 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
8505 (EMACS_USECS): Remove.
8506 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
8507 so multiply the arg by 1000 before storing it.
8508 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
8510 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
8511 Port to ns-resolution time stamps.
8512 (EMACS_TIME_NEG_P): Remove; replaced by....
8513 (EMACS_TIME_SIGN): New macro.
8514 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
8515 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.

8517 (make_timeval, make_lisp_time, decode_time_components): New decls.
8518 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
8519 that it mishandled time_t overflow. You can't compare by subtracting!
8520 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
8521 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
8523 * term.c: Include <sys/time.h>.
8524 (timeval_to_Time): New function, for proper overflow wraparound.

8529 (Fprimitive_undo): Use them when restoring time stamps.
8531 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
8532 (w32_get_internal_run_time):
8533 Port to higher-resolution Emacs time stamps.
8534 (ltime): Now accepts single 64-bit integer, as that's more convenient
8537 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
8539 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
8540 for compatibility with pselect. Support ns-resolution time stamps.
8542 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
8544 * xselect.c (wait_for_property_change, x_get_foreign_selection):
8545 Check for time stamp overflow, and support ns-resolution time stamps.
8547 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
8548 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
8549 (timeval_subtract): Remove; no longer needed.
8550 (XTflash, XTring_bell, x_wait_for_event):
8551 Port to ns-resolution time stamps. Don't assume time_t is signed.
8553 2012-06-22 Chong Yidong <cyd@gnu.org>
8555 * xdisp.c (x_consider_frame_title): Revert last change.
8557 2012-06-22 Eli Zaretskii <eliz@gnu.org>
8559 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
8560 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
8561 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
8562 staticidx goes up to 1597 out of 1600 = 0x640.)
8564 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
8566 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
8567 Otherwise, the umask might be mistakenly 0 while handling input signals.
8569 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
8571 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

8576 * font.c, image.c, keyboard.c, lread.c, menu.c, minibuf.c, msdos.c:
8577 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
8578 access to `contents' member of Lisp_Vector objects with AREF and ASET
8581 2012-06-19 Chong Yidong <cyd@gnu.org>
8583 * frame.c (delete_frame): When selecting a frame on a different
8584 text terminal, do not alter the terminal's top-frame.

8587 frame's selected window and its terminal's top-frame.
8588 (unwind_format_mode_line): Restore them.
8589 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
8591 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
8592 since tty frames can be explicitly named.
8593 (prepare_menu_bars): Likewise.
8595 * term.c (Ftty_top_frame): New function.
8597 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

8613 gets killed during executing of this function (Bug#11665).
8614 Try to always return Qt when the buffer has been actually killed.

8616 run by this hook should not change the current buffer.

8646 * coding.c (produce_chars): Use ptrdiff_t, not int.
8648 * xterm.c (x_draw_underwave): Check for integer overflow.
8649 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

8653 * nsterm.m (x_free_frame_resources): Move xfree so freed memory isn't
8654 referenced (Bug#11583).

8742 * xdisp.c (set_cursor_from_row): Don't dereference glyphs_end.
8743 If all the glyphs of the glyph row came from strings, and we have no
8744 cursor positioning clues, put the cursor on the first glyph of the

8833 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
8834 code works fine either way, and efficiency is not a concern here,
8835 as the union type is for debugging, not for production.
8836 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
8837 Use an inline function on all platforms when using the union type,
8838 since this is simpler and 'static inline' can be used portably
8840 (LISP_INITIALLY_ZERO): New macro.
8841 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.

8982 * doprnt.c (doprnt): Truncate multibyte char correctly.
8983 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
8984 would mishandle a string argument "Xc" if X was a multibyte
8985 character of length 2: it would truncate after X's first byte
8986 rather than including all of X.

9052 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
9054 For a 'struct window', replace some Lisp_Object fields to
9055 bitfields where appropriate, remove unused fields.
9056 * window.h (struct window): Remove unused 'last_mark_x' and
9057 'last_mark_y' fields. Rename 'mini_p' field to 'mini',

9060 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
9061 fields from Lisp_Object to bitfield. Adjust users accordingly.
9063 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
9065 Pacify gcc -Wdouble-precision when using Xaw.

9067 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:

9069 and 'double' in a couple of places.
9071 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9073 * xdisp.c (handle_stop): Detect whether we have overlay strings
9074 loaded by testing it->current.overlay_string_index to be
9075 non-negative, instead of checking whether n_overlay_strings is
9076 positive. (Bug#11587)
9078 2012-05-31 Chong Yidong <cyd@gnu.org>
9080 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
9082 * doc.c (Fsubstitute_command_keys): Doc fix.
9084 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9086 * search.c (search_buffer): Remove calls to
9087 r_alloc_inhibit_buffer_relocation, as it is now called by
9088 maybe_unify_char, which was the cause of relocation of buffer text
9091 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9093 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
9094 for the duration of call to load_charset, to avoid problems with
9095 callers of maybe_unify_char that access buffer text through C
9098 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
9099 decrement the inhibition flag, instead of just setting or
9102 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
9104 Remove obsolete '#define static' cruft.
9105 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
9106 This #undef was "temporary" in 2000; it is no longer needed
9107 now that '#define static' has gone away.
9108 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
9109 (gray_bitmap_bits): Remove; no longer needed.
9110 All uses replaced with definiens.
9111 * xterm.c: Include "bitmaps/gray.xbm".
9113 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
9115 Clean up __executable_start, monstartup when --enable-profiling.
9116 The following changes affect the code only when profiling.
9117 * dispnew.c (__executable_start): Rename from safe_bcopy.
9118 Define only on platforms that need it.
9119 * emacs.c: Include <sys/gmon.h> when profiling.
9120 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
9121 (__executable_start): Remove decl, since lisp.h does it now.
9122 (safe_bcopy): Remove decl; no longer has that name.
9123 (main): Coalesce #if into single bit of code, for simplicity.
9124 Cast pointers to uintptr_t, since standard libraries want integers
9126 * lisp.h (__executable_start): New decl.
9128 2012-05-31 Glenn Morris <rgm@gnu.org>
9130 * image.c (Fimagemagick_types): Doc fix.
9132 2012-05-30 Jim Meyering <meyering@redhat.com>
9134 * callproc.c (Fcall_process_region): Include directory component

9147 (Qdefun): Move from eval.c.
9148 * lisp.h (Qdefun): Remove.
9149 * lread.c (read1): Tiny simplification.
9151 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
9153 Do not create empty overlays with the evaporate property (Bug#9642).
9154 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
9155 Bug#9642, but explicitly check that the buffer the overlay would
9156 be moved to is live and rearrange lines to make sure that errors
9157 will not put the overlay in an inconsistent state.
9158 (Fdelete_overlay): Cosmetics.
9160 2012-05-28 Eli Zaretskii <eliz@gnu.org>
9162 * w32term.c (my_bring_window_to_top): New function.
9163 (x_raise_frame): Use handle returned by DeferWindowPos, which
9164 could be different from the original one.
9165 Call my_bring_window_to_top instead of my_set_foreground_window.
9168 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
9169 by calling BringWindowToTop.
9171 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
9172 (WM_EMACS_END): Increase by one.
9174 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
9176 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
9177 This avoids undefined behavior that might cause the eassert
9178 to not catch an out-of-range value.
9180 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
9182 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
9183 Update dependencies.
9185 2012-05-27 Eli Zaretskii <eliz@gnu.org>
9187 * bidi.c (bidi_mirror_char): Fix last change.
9189 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
9191 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
9192 when referring to sectname field in printf format.
9194 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
9196 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
9197 Only r_alloc_inhibit_buffer_relocation needed to be added;
9198 the others were already declared.
9200 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
9201 before checking whether it's out of range. Put the check inside
9203 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
9205 2012-05-27 Ken Brown <kbrown@cornell.edu>
9207 * callproc.c (Fcall_process): Restore a line that was accidentally
9208 commented out in the 2011-02-13 change (bug#11547).
9210 2012-05-27 Eli Zaretskii <eliz@gnu.org>
9212 * lisp.h [REL_ALLOC]: Add prototypes for external functions
9213 defined on ralloc.c.
9215 * buffer.c [REL_ALLOC]: Remove prototypes of
9216 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
9217 they are now on lisp.h.
9219 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
9221 * search.c (search_buffer): Use it to inhibit relocation of buffer
9222 text while re_search_2 is doing its job, because re_search_2 is
9223 passed C pointers to buffer text. (Bug#11519)
9225 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
9228 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
9229 state after an additional call to move_it_in_display_line_to, keep
9230 the values of it->max_ascent and it->max_descent found for the
9232 (pos_visible_p): Revert the comparison against bottom_y to what it
9233 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
9236 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
9238 Fix coding-related core dumps with gcc -ftrapv.
9239 The code was computing A - B, where A and B are pointers, and B is
9240 random garbage. This can lead to core dumps on platforms that
9241 have special pointer registers, and it also leads to core dumps on
9242 x86-64 when compiled with gcc -ftrapv. The fix is to compute
9243 A - B only when B is initialized properly.
9244 * coding.c (coding_set_source, coding_set_destination): Return void.
9245 (coding_change_source, coding_change_destinations): New functions,
9246 with the old behaviors of coding_set_source and coding_set_destination.
9247 All callers that need an offset changed to use these new functions.
9249 2012-05-26 Glenn Morris <rgm@gnu.org>
9251 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
9253 2012-05-26 Eli Zaretskii <eliz@gnu.org>
9255 Extend mouse support on W32 text-mode console.
9256 * xdisp.c (draw_row_with_mouse_face):
9257 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
9259 * w32console.c: Include window.h.
9260 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
9262 (initialize_w32_display): Initialize mouse-highlight data.
9264 * w32inevt.c: Include termchar.h and window.h.
9265 (do_mouse_event): Support mouse-autoselect-window. When the mouse
9266 moves, call note_mouse_highlight. If help_echo changed, call
9267 gen_help_event to produce help-echo message in the echo area.
9268 Call clear_mouse_face if mouse_face_hidden is set in the mouse
9271 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
9273 * lread.c (read1): Simplify slightly to avoid an overflow warning
9274 with GCC 4.7.0 on x86-64.
9276 2012-05-26 Eli Zaretskii <eliz@gnu.org>
9278 * bidi.c (bidi_mirror_char): Revert last change: an int is
9279 definitely wide enough here.
9281 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
9283 Fix integer width and related bugs (Bug#9874).
9284 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
9285 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)

9291 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
9293 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9294 (allocate_pseudovector):
9295 Use int, not EMACS_INT, where int is wide enough.
9296 (inhibit_garbage_collection, Fgarbage_collect):
9297 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9298 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
9299 int might not be wide enough.
9300 (bidi_cache_search, bidi_cache_find, bidi_init_it)
9301 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)

9303 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
9304 (bidi_level_of_next_char, bidi_move_to_visually_next):
9305 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9306 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
9307 (Fkill_buffer, Fset_buffer_major_mode)
9308 (advance_to_char_boundary, Fbuffer_swap_text)

9311 (overlay_strings, recenter_overlay_lists)
9312 (adjust_overlays_for_insert, adjust_overlays_for_delete)
9313 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
9314 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
9315 (Foverlay_recenter, last_overlay_modification_hooks_used)
9316 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
9317 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9318 (validate_region): Omit unnecessary test for b <= e,
9319 since that's guaranteed by the previous test.
9320 (adjust_overlays_for_delete): Avoid pos + length overflow.
9321 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
9322 (report_overlay_modification):
9323 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9324 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
9325 Omit pointer cast, which isn't needed anyway, and doesn't work
9326 after the EMACS_INT -> ptrdiff_t change.
9327 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
9328 * buffer.h: Adjust decls to match defn changes elsewhere.
9329 (struct buffer_text, struct buffer):

9331 Use EMACS_INT, not int, where int might not be wide enough.
9332 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
9333 not int, to avoid needless 32-bit limit on 64-bit hosts.
9334 (exec_byte_code): Use tighter memory-full test, one that checks
9335 for alloca overflow. Don't compute the address of the object just
9336 before an array, as that's not portable. Use EMACS_INT, not
9337 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
9338 * callint.c (Fcall_interactively):
9339 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9340 * callproc.c (call_process_kill, Fcall_process):
9341 Don't assume pid_t fits into an Emacs fixnum.

9350 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
9351 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9352 (casify_object): Avoid integer overflow when overallocating buffer.
9353 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
9354 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
9355 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
9356 * category.h (CATEGORYP): Don't assume arg is nonnegative.
9357 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
9358 integers are now checked earlier. All uses replaced with XINT.
9360 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9361 For CCL_MapSingle, check that content and value are in int range.
9362 (ccl_driver, Fregister_code_conversion_map):
9363 Check that Vcode_version_map_vector is a vector.
9364 (resolve_symbol_ccl_program): Check that vector header is in range.
9365 Always copy the vector, so that we can check its contents reliably
9366 now rather than having to recheck each instruction as it's being
9367 executed. Check that vector words fit in 'int'.
9368 (ccl_get_compiled_code, Fregister_ccl_program)
9369 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
9370 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
9371 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
9372 contents are in range.
9373 (Fccl_execute_on_string): Check that status is in range.
9374 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
9375 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
9376 Accept and return EMACS_INT, not int, because callers can pass values
9378 (c_string_width, strwidth, lisp_string_width, chars_in_text)

9381 (str_as_unibyte, str_to_unibyte, string_count_byte8)
9382 (string_escape_byte8, Fget_byte):
9383 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9384 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
9385 avoid mishandling large integers.
9386 * character.h: Adjust decls to match defn changes elsewhere.
9387 * charset.c (load_charset_map_from_file, find_charsets_in_text)

9395 (Fdefine_charset_internal): Check ranges here, more carefully.
9396 Don't rely on undefined behavior with signed left shift overflow.
9397 Don't assume unsigned int fits into fixnum, or that fixnum fits
9398 into unsigned int. Don't require max_code to be a valid fixnum;
9399 that's not true for gb10830 4-byte on a 32-bit host. Allow
9400 invalid_code to be a cons, for the same reason. Require code_offset
9401 to be a character. Avoid int overflow if max_char is close
9403 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
9404 this is intended anyway and avoids some undefined behavior.
9405 (load_charset_map): Pass unsigned, not int, as 2nd arg of
9406 INDEX_TO_CODE_POINT, as that's what it expects.
9407 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
9408 * charset.h (DECODE_CHAR): Return int, not unsigned;
9409 this is what was intended anyway, and it avoids undefined behavior.
9410 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
9411 integer-overflow issues.
9412 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
9413 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
9414 where the argument is EMACS_INT, and this behavior is not intended.
9415 * chartab.c (Fmake_char_table, Fset_char_table_range)
9416 (uniprop_get_decoder, uniprop_get_encoder):
9417 Don't assume fixnum fits in int.
9418 * cmds.c (move_point): New function, that does the gist of
9419 Fforward_char and Fbackward_char, but does so while checking
9420 for integer overflow more accurately.
9421 (Fforward_char, Fbackward_char): Use it.
9422 (Fforward_line, Fend_of_line, internal_self_insert)
9423 (internal_self_insert):
9424 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9425 Fix a FIXME, by checking for integer overflow when calculating
9426 target_clm and actual_clm.

9456 (Funencodable_char_position, Fcheck_coding_systems_region)
9457 (get_translation, handle_composition_annotation, consume_chars):
9458 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9459 (consume_chars): Rewrite to not calculate an address outside buffer.
9460 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
9461 Don't access memory outside of the args array.
9462 (Fdefine_coding_system_internal): Check for charset-id overflow.
9463 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
9464 result of ENCODE_CHAR.
9465 * coding.h: Adjust decls to match defn changes elsewhere.
9466 (struct coding_system):
9467 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

9482 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9483 * data.c (let_shadows_buffer_binding_p, let_shadows_global_binding_p):
9484 Do not attempt to compute the address of the object just before a
9485 buffer; this is not portable.

10205 2012-05-14 Glenn Morris <rgm@gnu.org>
10207 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
10208 Put "libexec" before "bin", for the sake of init_callproc_1.
10210 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
10212 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
10214 * unexaix.c: Port to more-recent AIX compilers.
10215 (report_error, report_error_1, make_hdr, copy_sym)
10216 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
10217 Make arguments const char *, not char *, to avoid violations of C
10218 standard and to fix some AIX warnings reported by Gilles Pion.
10220 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10222 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
10223 already have overlays loaded.
10224 (handle_single_display_spec): Before returning without displaying
10225 fringe bitmap, synchronize the bidi iterator with the main display
10226 iterator, by calling iterate_out_of_display_property.
10227 (iterate_out_of_display_property): Detect buffer iteration by
10228 testing that it->string is a Lisp string.
10229 (get_next_display_element): When the current object is exhausted,
10230 and there's something on it->stack, call set_iterator_to_next to
10231 proceed with what's on the stack, instead of returning zero.
10232 (set_iterator_to_next): If called at the end of a Lisp string,
10233 proceed to consider_string_end without incrementing string
10234 position. Don't increment display vector index past the end of
10235 the display vector. (Bug#11417)
10236 (pos_visible_p): Don't report a position visible when move_it_to
10237 stopped at the last line of window, which happens to be scanned
10238 backwards by the bidi iteration. (Bug#11464)
10240 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10242 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
10243 and right-margin display specs even if the spec is invalid or we
10244 are on a TTY, and thus unable to display on the fringes.
10245 That's because the text with the property will not be displayed anyway,
10246 so we need to signal to the caller that this is a "replacing"
10247 display spec. This fixes display when the spec is invalid or we
10250 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
10252 * unexaix.c (make_hdr): Fix typo in prototype.
10253 This bug broke the build on AIX. Problem reported by Gilles Pion.
10255 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
10257 * keyboard.c (kbd_buffer_get_event): Read special events also in
10258 batch mode. (Bug#11415)
10260 2012-05-12 Glenn Morris <rgm@gnu.org>
10262 * ns.mk: Update for ns_appbindir no longer having trailing "/".
10264 2012-05-12 Eli Zaretskii <eliz@gnu.org>
10266 * lisp.mk (lisp): Add newcomment.elc.
10268 2012-05-12 Glenn Morris <rgm@gnu.org>
10270 * Makefile.in (MKDIR_P): New, set by configure.
10271 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
10273 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
10275 Remove unused function hourglass_started.
10276 * dispextern.h (hourglass_started):
10277 * w32fns.c (hourglass_started):
10278 * xdisp.c (hourglass_started): Remove.
10280 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
10282 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
10283 Update dependencies.
10285 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
10287 * xgselect.c (xg_select): Put maxfds+1 into a var.
10288 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
10290 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
10292 2012-05-10 Dave Abrahams <dave@boostpro.com>
10294 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
10295 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
10297 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
10299 * dbusbind.c (xd_registered_buses): New internal Lisp object.
10300 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
10301 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
10302 Initialize xd_registered_buses.
10304 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
10306 Untag more efficiently if USE_LSB_TAG.
10307 This is based on a proposal by YAMAMOTO Mitsuharu in
10308 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
10309 For an admittedly artificial (nth 8000 longlist) benchmark on
10310 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
10311 Emacs's overall text size by 1%.
10312 * lisp.h (XUNTAG): New macro.
10313 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
10314 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
10315 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
10316 * eval.c (Fautoload):
10317 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
10318 * frame.h (XFRAME): Use XUNTAG.
10320 Port recent dbusbind.c changes to 32-bit --with-wide-int.
10321 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
10322 Remove unportable assumptions about print widths of types like
10324 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
10325 intptr_t when converting between pointer and integer, to avoid GCC
10326 warnings about wrong width.
10328 2012-05-09 Eli Zaretskii <eliz@gnu.org>
10330 * w32proc.c (new_child): Force Windows to reserve only 64KB of
10331 stack for each reader_thread, instead of defaulting to 8MB
10332 determined by the linker. This avoids failures in creating
10333 subprocesses on Windows 7, see the discussion in this thread:
10334 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
10336 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
10338 Fix up display of the *Minibuf-0* buffer in the mini window.
10339 * keyboard.c (read_char): Don't clear the echo area if there's no
10341 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
10342 contents of *Minibuf-0*) if there's no message displayed in its stead.
10344 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
10346 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
10349 2012-05-06 Chong Yidong <cyd@gnu.org>
10351 * lisp.mk (lisp): Update.
10353 2012-05-05 Jim Meyering <meyering@redhat.com>
10355 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
10357 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
10359 * data.c (PUT_ERROR): New macro.
10360 (syms_of_data): Use it. Add new error type `user-error'.
10361 * undo.c (user_error): New function.
10362 (Fprimitive_undo): Use it.
10363 * print.c (print_error_message): Adjust print style for `user-error'.
10364 * keyboard.c (user_error): New function.
10365 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
10367 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
10369 Do not limit current-time-string to years 1000..9999.
10370 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
10371 (Fcurrent_time_string): Support any year that is supported by the
10372 underlying localtime representation. Don't use asctime, as it
10373 has undefined behavior for years outside the range -999..9999.
10375 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
10377 Fix race conditions involving setenv, gmtime, localtime, asctime.
10378 Without this fix, interrupts could mess up code that uses these
10379 nonreentrant functions, since setting TZ invalidates existing
10380 tm_zone or tzname values, and since most of these functions return
10381 pointers to static storage.
10382 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
10383 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
10384 Grow the critical sections to include not just invoking
10385 localtime/gmtime, but also accessing these functions' results
10386 including their tm_zone values if any, and any related TZ setting.
10387 (format_time_string): Last arg is now struct tm *, not struct tm **,
10388 so that the struct tm is saved in the critical section.
10389 All callers changed. Simplify allocation of initial buffer, partly
10390 motivated by the fact that memory allocation needs to be outside
10391 the critical section.
10393 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
10395 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
10396 with RESET_INTERVAL.
10398 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
10399 Remove duplicated buffer name initialization.
10401 2012-05-02 Jim Meyering <jim@meyering.net>
10403 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
10405 * xfns.c (x_window): Use xstrdup (Bug#11375).
10407 2012-05-02 Eli Zaretskii <eliz@gnu.org>
10409 * xdisp.c (pos_visible_p): If already at a newline from the
10410 display string before the 'while' loop, don't walk back the glyphs
10411 from it3.glyph_row. Solves assertion violation when the display
10412 string begins with a newline (egg.el). (Bug#11367)
10414 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
10416 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
10419 2012-05-01 Glenn Morris <rgm@gnu.org>
10421 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
10422 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
10423 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
10424 All were removed before 23.1.
10426 * dispnew.c: Remove HAVE_LIBNCURSES test;
10427 it is always true on relevant platforms.
10429 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
10430 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
10432 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
10434 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
10436 * .gdbinit (xpr): Remove checks for no longer existing misc types.
10437 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
10440 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
10442 Do not avoid creating empty evaporating overlays (Bug#9642).
10443 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
10444 That is, do not delete an evaporating overlay if it becomes
10445 empty after its bounds are adjusted to fit within its buffer.
10446 This fix caused other problems, and I'm reverting it until we get
10447 to the bottom of them.
10449 2012-04-27 Chong Yidong <cyd@gnu.org>
10451 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
10453 2012-04-27 Eli Zaretskii <eliz@gnu.org>
10455 * xdisp.c (pos_visible_p): If the window start position is beyond
10456 ZV, start the display from buffer beginning. Prevents assertion
10457 violation in init_iterator when the minibuffer window is scrolled
10458 via the scroll bar.
10460 * window.c (window_scroll_pixel_based): Likewise.
10462 2012-04-27 Chong Yidong <cyd@gnu.org>
10464 * keymap.c (where_is_internal): Doc fix (Bug#10872).
10466 2012-04-27 Glenn Morris <rgm@gnu.org>
10468 * fileio.c (Fcopy_file, Fset_file_selinux_context):
10469 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
10471 2012-04-27 Eli Zaretskii <eliz@gnu.org>
10473 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
10474 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
10476 2012-04-26 Eli Zaretskii <eliz@gnu.org>
10478 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
10479 display element, check also the underlying string or buffer
10480 character. (Bug#11341)
10482 * w32menu.c: Include w32heap.h.
10483 (add_menu_item): If the call to AppendMenuW (via
10484 unicode_append_menu) fails, disable Unicode menus only if we are
10485 running on Windows 9X/Me.
10487 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
10489 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
10490 (xgetint): Add missing shift for LSB tags.
10492 2012-04-24 Martin Rudalics <rudalics@gmx.at>
10494 * keyboard.c (read_char): Don't wipe echo area for select window
10495 events: These might get delayed via `mouse-autoselect-window'
10498 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
10500 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
10501 manipulation of :loaded-from data.
10503 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
10505 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
10506 now a cons (bug#11311).
10508 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
10510 Do not create empty overlays with the evaporate property (Bug#9642).
10511 * buffer.c (Fmove_overlay): Delete an evaporating overlay
10512 if it becomes empty after its bounds are adjusted to fit within
10513 its buffer. Without this fix, in a nonempty buffer (let ((o
10514 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
10515 yields an empty overlay that has the evaporate property, which is
10516 not supposed to happen.
10518 Fix minor GTK3 problems found by static checking.
10519 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
10520 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
10521 (struct _EmacsFixedClass, emacs_fixed_get_type):
10522 Move decls here from emacsgtkfixed.h, since they needn't be public.
10523 (emacs_fixed_get_type): Now static.
10524 (emacs_fixed_class_init): Omit unused local.
10525 (emacs_fixed_child_type): Remove; unused.
10526 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
10527 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
10528 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
10529 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
10530 (EMACS_FIXED_GET_CLASS): Remove; unused.
10531 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
10533 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
10534 Problem reported by Juanma Barranquero for Windows -Wunused-function.
10536 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
10538 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
10539 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
10540 (__malloc_size_t, __malloc_ptrdiff_t):
10541 Remove. All uses removed, replaced by the definiens if needed,
10542 since we can assume C89 or better now.
10543 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

10551 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
10552 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
10553 Define using prototypes, not old style.
10554 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
10555 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
10556 (align): Don't assume that signed integer overflow wraps around.
10557 Omit unused local var.
10558 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
10559 (_free_internal_nolock, memalign, mallochook, reallochook):
10560 Omit no-longer-needed casts.
10561 (valloc): Use getpagesize, not __getpagesize.
10562 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
10563 (struct hdr): The 'magic' member is now size_t, not unsigned long.
10565 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
10567 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
10569 Move functions from C to Lisp. Make non-blocking method calls
10570 the default. Implement further D-Bus standard interfaces.
10572 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.

10588 (xd_signature, xd_append_arg): Allow float for integer types.
10589 (xd_get_connection_references): New function.
10590 (xd_get_connection_address): Rename from xd_initialize.
10591 Return cached address.
10592 (xd_remove_watch): Do not unset $DBUS_SESSION_BUS_ADDRESS.
10593 (xd_close_bus): Rename from Fdbus_close_bus. Not needed on Lisp

10600 (Fdbus_method_return_internal, Fdbus_method_error_internal)
10601 (Fdbus_send_signal, Fdbus_register_service)

10612 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
10614 Fix GC_MALLOC_CHECK debugging output on 64-bit hosts.
10615 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
10616 Do not assume ptrdiff_t is the same width as 'int'.
10618 * alloc.c: Handle unusual debugging option combinations.
10619 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
10620 since the two debugging options are incompatible.
10621 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
10623 (mem_init, mem_insert, mem_insert_fixup):
10624 Define if GC_MARK_STACK || GC_MALLOC_CHECK.
10625 (NEED_MEM_INSERT): Remove; no longer needed.
10627 2012-04-22 Leo Liu <sdl.web@gmail.com>

10631 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
10633 * sysdep.c [__FreeBSD__]: Minor cleanups.
10634 (list_system_processes, system_process_attributes) [__FreeBSD__]:
10635 Use Emacs indenting style more consistently. Avoid some casts.
10636 Use 'double' consistently rather than mixing 'float' and 'double'.

10654 * print.c (print_preprocess): Only check print_depth if print-circle
10656 (print_object): Check for cycles even when print-circle is nil and
10657 print-gensym is t, but only check print_depth if print-circle is nil.

10661 * process.c (wait_reading_process_output): If EIO occurs on a pty,
10662 set the status to "failed" and ensure that sentinel is run.
10664 2012-04-20 Glenn Morris <rgm@gnu.org>
10666 * process.c (Fset_process_inherit_coding_system_flag)
10667 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

10677 farther than the first row after the header line, if any.
10678 Don't consider the header-line row as "partially visible", even if
10679 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
10681 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

10691 (WARN_CFLAGS, WERROR_CFLAGS): New macros.
10692 (ALL_CFLAGS): Use new macros rather than old.
10693 * process.c: Ignore -Wstrict-overflow to work around GCC bug 52904.

10695 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
10696 -Wunused-result, -Wunused-variable. This should go away once
10697 the Emacs and Gnulib regex code is merged.
10698 (xmalloc, xrealloc): Now static.
10700 2012-04-17 Paul Eggert <eggert@cs.ucla.edu>

10717 New extern decls, to avoid calling undeclared functions.
10718 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
10719 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
10720 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
10721 (NEED_MEM_INSERT): New macro.
10722 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
10723 Remove one incorrect comment and fix another.

10737 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
10738 Remove decls. This fixes an "It stinks!".
10740 * alloc.c (which_symbols): Fix alignment issue / type clash.
10742 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
10744 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
10745 (struct Lisp_Misc_Any): Likewise.
10746 (struct Lisp_Free): Likewise.
10747 * alloc.c (union aligned_Lisp_Symbol): Define.

10757 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
10758 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
10759 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
10760 * s/netbsd.h, s/sol2-6.h:
10761 Remove definition of GC_MARK_STACK, since the default now works.
10762 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
10763 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
10764 no longer the default.
10765 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
10767 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
10769 * lread.c (lisp_file_lexically_bound_p):

10772 2012-04-14 Eli Zaretskii <eliz@gnu.org>
10774 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
10775 "unchanged" if its end.pos is beyond ZV. (Bug#11199)

10786 2012-04-13 Reuben Thomas <rrt@sc3d.org>
10788 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
10790 2012-04-11 Daniel Colascione <dancol@dancol.org>
10792 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
10793 against is gone. It's better to use vfork now so that when Cygwin
10794 gains a new, working vfork, we use it automatically (bug#10398).
10796 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
10798 * window.c (save_window_save): Obey window-point-insertion-type.

10814 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
10816 * w32.c (w32_delayed_load): Record the full path of the library
10817 being loaded (bug#10424).
10819 2012-04-09 Glenn Morris <rgm@gnu.org>
10821 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
10822 not just in the obarray, before snarfing them. (Bug#11036)

10827 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
10829 * process.c (make_process):
10830 * process.h: Add integer `gnutls_handshakes_tried' member to

10839 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
10840 attempts per process (connection).
10842 2012-04-09 Chong Yidong <cyd@gnu.org>
10844 * eval.c (Fuser_variable_p, user_variable_p_eh)
10845 (lisp_indirect_variable): Functions deleted.
10846 (Fdefvar): Caller changed.
10848 * callint.c (Finteractive, Fcall_interactively):
10849 * minibuf.c (Fread_variable): Callers changed.
10851 2012-04-09 Eli Zaretskii <eliz@gnu.org>
10853 * xdisp.c (set_cursor_from_row): If the display string appears in
10854 the buffer at position that is closer to point than the position
10855 after the display string, display the cursor on the first glyph of
10856 the display string. Fixes cursor display when a 'display' text
10857 property immediately follows invisible text. (Bug#11094)
10859 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
10861 composite.c: use 'double' consistently
10862 * composite.c (get_composition_id): Use 'double' consistently
10863 instead of converting 'float' to 'double' and vice versa; this is
10864 easier to understand and avoids a GCC warning.
10866 2012-04-09 Glenn Morris <rgm@gnu.org>
10868 * Makefile.in: Generate leim-list with bootstrap-emacs, in
10869 preparation for dumping it with emacs. (Bug#4789)
10870 (leimdir): New variable.

10890 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
10891 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
10892 (mark_memory): Mark Lisp_Objects only if pointers might hide in
10893 objects, as mark_maybe_pointer will catch them otherwise.
10894 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
10895 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

10906 * makefile.w32-in (OBJ2): Add xml.$(O).
10907 (GLOBAL_SOURCES): Add xml.c.
10908 ($(BLD)/xml.$(O)): New dependency list.
10910 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
10911 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
10912 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
10913 [!WINDOWSNT]: New macros.
10914 (init_libxml2_functions, libxml2_loaded_p): New functions.
10915 (parse_region): Call fn_xmlCheckVersion instead of using the macro
10916 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
10917 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
10918 Calls xmlCleanupParser only if libxml2 was loaded (or statically
10920 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
10921 Call init_libxml2_functions before calling libxml2 functions.
10922 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
10924 * emacs.c: Don't include libxml/parser.h.
10925 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
10926 xmlCleanupParser directly.
10928 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
10930 2012-04-07 Eli Zaretskii <eliz@gnu.org>
10932 * indent.c (Fvertical_motion): If there is a display string at
10933 point, use it.vpos to compute how many lines to backtrack after
10934 move_it_to point. (Bug#11133)
10936 2012-04-06 Eli Zaretskii <eliz@gnu.org>
10938 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
10939 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
10940 about subtle differences between FETCH_CHAR* and STRING_CHAR*
10941 macros related to unification of CJK characters. For the details,
10942 see the discussion following the message here:
10943 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
10945 2012-04-04 Chong Yidong <cyd@gnu.org>
10947 * keyboard.c (Vdelayed_warnings_list): Doc fix.
10949 2012-04-01 Eli Zaretskii <eliz@gnu.org>
10951 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
10952 instead of alloca. (Bug#11138)
10954 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
10956 * w32menu.c (is_simple_dialog): Properly check lisp types.
10959 2012-03-31 Eli Zaretskii <eliz@gnu.org>
10961 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
10962 position we get to after a call to move_it_to fails the
10963 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
10964 only if we wind up in a string from display property. (Bug#11063)
10966 * window.c (Fdelete_other_windows_internal): Invalidate the row
10967 and column information about mouse highlight, so that redisplay
10968 restores it after reallocating the glyph matrices. (Bug#7464)
10970 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
10971 string comes from a `display' text property, use the buffer
10972 position of that property as if we actually saw that position in
10974 (move_it_by_lines): Remove the assertion that
10975 "it->current_x == 0 && it->hpos == 0" which can be legitimately
10976 violated when there's a before-string at the beginning of a line.
10979 2012-03-30 Eli Zaretskii <eliz@gnu.org>
10981 * xdisp.c (append_space_for_newline): If the default face was
10982 remapped, use the remapped face for the appended newline.
10983 (extend_face_to_end_of_line): Use the remapped default face for
10984 extending the face to the end of the line.
10985 (display_line): Call extend_face_to_end_of_line when the default
10986 face was remapped. (Bug#11068)

11008 * keyboard.c (Vselection_inhibit_update_commands): New variable.
11009 (command_loop_1): Use it; inhibit selection update for

11014 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
11016 2012-03-25 Kenichi Handa <handa@m17n.org>
11018 * dispextern.h (struct glyph): Change the bit length of
11019 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
11021 2012-03-24 Eli Zaretskii <eliz@gnu.org>
11023 * s/ms-w32.h (tzname): Include time.h before redirecting to

11032 !SYNC_INPUT. (Bug#11080)
11034 2012-03-23 Eli Zaretskii <eliz@gnu.org>
11036 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
11037 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
11038 when fetching a multibyte character consumes more bytes than
11039 CHAR_BYTES returns, due to unification of CJK characters in
11040 string_char. (Bug#11073)
11042 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
11044 * process.c (wait_reading_process_output): Handle pty disconnect
11045 by refraining from sending oneself a SIGCHLD (bug#10933).
11047 2012-03-22 Chong Yidong <cyd@gnu.org>
11049 * dispextern.h (struct it): New member string_from_prefix_prop_p.
11051 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
11052 Mark string as coming from a prefix property.
11053 (handle_face_prop): Use default face for prefix strings (Bug#4281).
11054 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
11056 2012-03-21 Chong Yidong <cyd@gnu.org>
11058 * xfaces.c (Vface_remapping_alist): Doc fix.
11060 2012-03-20 Eli Zaretskii <eliz@gnu.org>

11074 it fit in a valid range (Bug#11003).
11076 2012-03-18 Eli Zaretskii <eliz@gnu.org>
11078 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
11079 that is not from display property, accept the row as a "cursor
11080 row" if one of the string's character has a non-nil `cursor'
11081 property. Fixes cursor positioning when there are newlines in
11082 overlay strings, e.g. in icomplete.el. (Bug#11035)
11084 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
11086 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
11088 2012-03-12 Chong Yidong <cyd@gnu.org>
11090 * eval.c (inhibit_lisp_code): Rename from
11091 inhibit_window_configuration_change_hook; move from window.c.
11093 * xfns.c (unwind_create_frame_1, Fx_create_frame):

11125 position past the first glyph_row that ends at ZV. (Bug#10902)
11126 (redisplay_window, next_element_from_string): Fix typos in
11128 (redisplay_window): Pass to move_it_vertically the margin in

11135 2012-02-29 Eli Zaretskii <eliz@gnu.org>
11137 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
11138 push_it before setting up the iterator for the first overlay
11139 string, even if we have an empty string loaded.
11140 (next_overlay_string): If there's an empty string on the iterator
11141 stack, pop the stack. (Bug#10903)
11143 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
11145 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
11146 Suggested by Stefan Monnier in
11147 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
11148 * alloc.c (widen_to_Lisp_Object): New static function.
11149 (mark_memory): Also mark Lisp_Objects by fetching pointer words
11150 and widening them to Lisp_Objects. This would work even if
11151 USE_LSB_TAG is defined and wide integers are used, which might
11152 happen in a future version of Emacs.
11154 2012-02-25 Chong Yidong <cyd@gnu.org>
11156 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

11165 * keyboard.c (process_special_events): Handle all X selection
11166 requests in kbd_buffer, not just the next one (Bug#8869).
11168 2012-02-23 Chong Yidong <cyd@gnu.org>
11170 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
11171 call when setting menu-bar-lines and tool-bar-lines parameters.
11172 (unwind_create_frame_1): New helper function.
11174 * window.c (inhibit_window_configuration_change_hook): New var.

11195 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
11196 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
11197 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
11198 It's useless in that case, and it can cause problems on hosts
11199 that allocate halves of EMACS_INT values separately.
11200 Reported by Dan Horák. Diagnosed by Andreas Schwab in
11201 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
11202 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
11203 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
11204 it avoids undefined behavior on hosts where shifting right by more
11205 than the word width has undefined behavior.
11207 2012-02-19 Chong Yidong <cyd@gnu.org>
11209 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
11210 (Funhandled_file_name_directory, Ffile_name_as_directory)

11229 2012-02-15 Chong Yidong <cyd@gnu.org>
11231 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is

11250 as that creates a dangerous corner case.
11252 * window.c (Fdelete_window_internal): Invalidate the mouse
11253 highlight (Bug#9904).

11287 * buffer.c (Fbuffer_local_variables)
11288 (buffer_lisp_local_variables): Handle unbound vars correctly;
11289 don't let Qunbound leak into Lisp.
11291 2012-02-07 Glenn Morris <rgm@gnu.org>
11293 * image.c (Fimagemagick_types): Doc fix.
11295 * image.c (imagemagick-render-type): Change it from a lisp object
11296 to an integer. Move the doc here from the lisp manual.

11330 Handle overflow when computing char display width (Bug#9496).
11331 * character.c (char_width): Return EMACS_INT, not int.
11332 (char_width, c_string_width): Check for overflow when
11333 computing the width; this is possible now that individual
11334 characters can have unbounded width. Problem introduced

11366 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
11367 first 2 arguments are identical. This makes inserting large
11368 output from a subprocess an order of magnitude faster on
11369 MS-Windows, where all sbrk'ed memory is always contiguous.

11989 is set, removing the need for VIRT_ADDRESS_VARIES.
11990 (PURE_P): Use a more-efficient implementation that needs just one

12006 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
12007 behave as if the cursor position were at the window margin.
12009 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
12010 and the cursor position is out of bounds, behave as if the cursor
12011 position were at the window margin. (Bug#10075)
12013 2011-11-18 Chong Yidong <cyd@gnu.org>
12015 * window.c (Fwindow_combination_limit): Make first argument

12037 compute_line_metrics.
12038 (compute_line_metrics): Call row_hash, instead of computing the
12041 * dispnew.c (verify_row_hash): Call row_hash for computing the
12042 hash code of a row, instead of duplicating code from xdisp.c.
12044 * dispextern.h (row_hash): Add prototype.
12046 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
12048 * frame.c (delete_frame): Don't delete the terminal when the last

12088 Fixes assertion violations in row_equal_p. (Bug#10035)
12090 2011-11-14 Juanma Barranquero <lekktu@gmail.com>

12231 Otherwise, these inline functions do not conform to C99 and
12232 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
12233 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
12234 * intervals.c (adjust_intervals_for_insertion)

12237 (static_offset_intervals): Remove.
12238 (offset_intervals): Rewrite using the old contents of
12239 static_offset_intervals. The old version didn't conform to C99
12240 because an extern inline function contained a reference to an
12241 identifier with static linkage.

12504 * gnutls.c (emacs_gnutls_deinit): New function.
12505 Deallocate credentials structures as well as calling gnutls_deinit.
12506 (Fgnutls_deinit, Fgnutls_boot): Use it.
12508 * process.c (make_process): Initialize GnuTLS credentials to NULL.
12509 (deactivate_process): Call emacs_gnutls_deinit.
12511 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
12513 * image.c (x_create_x_image_and_pixmap):
12514 * w32.c (sys_rename, w32_delayed_load):
12515 * w32font.c (fill_in_logfont):
12516 * w32reg.c (x_get_string_resource): Silence compiler warnings.
12518 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
12520 * w32fns.c (w32_default_color_map): New function,
12521 extracted from Fw32_default_color_map.
12522 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
12524 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
12526 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
12528 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
12530 * keyboard.c (test_undefined): New function (bug#9751).
12531 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
12533 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
12535 * sysdep.c (init_sys_modes): Fix the check for the controlling
12536 terminal (Bug#6649).
12538 2011-10-20 Eli Zaretskii <eliz@gnu.org>
12540 * dispextern.h (struct bidi_it): New member next_en_type.
12542 * bidi.c (bidi_line_init): Initialize the next_en_type member.
12543 (bidi_resolve_explicit_1): When next_en_pos is valid for the
12544 current character, check also for next_en_type being WEAK_EN.
12545 (bidi_resolve_weak): Don't enter the expensive loop if the current
12546 position is before next_en_pos. Record the bidi type of the first
12547 non-ET, non-BN character we find, in addition to its position.
12548 (bidi_level_of_next_char): Invalidate next_en_type when
12549 next_en_pos is over-stepped.
12551 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
12553 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
12554 * editfns.c: Rewrite current-time-zone so that it invokes
12555 the equivalent of (format-time-string "%Z") to get the time zone name.
12556 This fixes a bug when the time zone name contains characters that
12557 need converting from the system time locale to Emacs internal format.
12558 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
12559 that patch fixed format-time-string to do the conversion, but
12560 I forgot to fix current-time-zone.
12561 (format_time_string): New function, containing most of
12562 what Fformat_time_string used to contain.
12563 (Fformat_time_string): Rewrite in terms of format_time_string.
12564 This doesn't change this function's behavior.
12565 (current-time-zone): Rewrite to use format_time_string.
12566 This fixes the bug reported by Michael Schierl in
12567 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
12568 Jason Rumney's 2007-06-07 change worked around this bug, but
12570 * systime.h (tzname, timezone): Remove no-longer-used declarations.
12572 2011-10-19 Eli Zaretskii <eliz@gnu.org>
12574 * xdisp.c (start_display): If the character at POS is displayed
12575 via a display vector, reset IT->current.dpvec_index to zero.
12576 (try_window_reusing_current_matrix): If a line ends in a display
12577 vector or the next line starts in a display vector, continue
12578 redrawing the window even though the character position of
12579 start_row was reached.
12582 2011-10-18 Chong Yidong <cyd@gnu.org>
12584 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
12585 with nobreak-char-display too.
12587 2011-10-18 Eli Zaretskii <eliz@gnu.org>
12589 Fix part 3 of bug#9771.
12590 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
12591 (bidi_resolve_neutral): Don't enter the expensive loop looking for
12592 non-neutral characters if the current character is a paragraph
12593 separator (a.k.a. Newline). This avoids running the same
12594 expensive loop twice, once when we consume the preceding newline
12595 and the other time when the line actually needs to be displayed.
12596 Avoid the loop when we see neutrals on the base embedding level
12597 following a character whose directionality is the same as the
12598 paragraph's. This avoids running the expensive loop when a line
12599 ends in a long sequence of neutrals, like control characters.
12600 Add assertion against STRONG_AL type. Slightly rearrange code
12601 that determines the type of a neutral given the first non-neutral
12603 (bidi_level_of_next_char): Set next_en_pos to zero when
12604 invalidating its info.
12606 2011-10-17 Eli Zaretskii <eliz@gnu.org>
12608 * xdisp.c (push_display_prop): Determine whether to record string
12609 or buffer position by IT->string, not by IT->method. Allow
12610 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
12611 (move_it_vertically_backward): Don't look for character position
12612 immediately after the newline when in a continuation line.
12615 2011-10-15 Martin Rudalics <rudalics@gmx.at>
12617 * window.c (coordinates_in_window): Rewrite and delabelize
12618 vertical border check. (Bug#5357) (Bug#9618)
12620 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
12622 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
12623 errors in XSetWindowBorder (bug#9310).
12625 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
12627 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
12628 avoid crash when xmalloc overrun checking is enabled.
12630 2011-10-13 Eli Zaretskii <eliz@gnu.org>
12632 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
12633 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
12634 cursor motion with <left> and <right> arrow keys.
12636 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
12637 some callers set that themselves.
12639 2011-10-12 Eli Zaretskii <eliz@gnu.org>
12641 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
12642 display string and the previous row comes from the same string and
12643 is empty. (Bug#9739) (Bug#9738)
12645 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
12647 * doc.c (get_doc_string): Encode file name (bug#9735).
12649 2011-10-12 Eli Zaretskii <eliz@gnu.org>
12651 * bidi.c (bidi_level_of_next_char):
12652 * xdisp.c (get_visually_first_element): Remove old incorrect
12653 comments regarding the Unicode Line Separator character.
12655 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
12657 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
12659 * alloc.c (Fgc_status): Do not access beyond zombies array
12660 boundary if nzombies > MAX_ZOMBIES.
12661 * alloc.c (dump_zombies): Add missing format specifier.
12663 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
12665 * xdisp.c (set_cursor_from_row): Simplify conditionals,
12666 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
12668 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
12669 Some packages use them to denote characters with modifiers.
12671 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
12673 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
12674 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
12675 matching a pp-number. Rename parameter var to var1.
12677 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
12679 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
12681 2011-10-08 Glenn Morris <rgm@gnu.org>
12683 * callint.c (Fcall_interactively): Give a more explicit error for the
12684 'c' case with a non-character input. (Bug#8479)
12686 2011-10-08 Eli Zaretskii <eliz@gnu.org>
12688 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
12690 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
12691 lines that are hscrolled on the left.
12693 * dispnew.c (buffer_posn_from_coords): Account for a possible
12694 presence of header-line. (Bug#4426)
12696 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
12698 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
12699 Don't advertise functionality which we discourage or doesn't work.
12701 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
12703 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
12704 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
12705 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
12706 this makes Emacs dump core during garbage collection on rare
12707 occasions. sizeof is obviously inferior to offsetof here, so
12708 stick with offsetof.
12709 (GC_POINTER_ALIGNMENT): New macro.
12710 (mark_memory): Omit 3rd (offset) arg; caller changed.
12711 Don't assume EMACS_INT alignment is the same as pointer alignment.
12713 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
12715 * keyboard.c (read_key_sequence_remapped): New var.
12716 (read_key_sequence): Compute remapping in the right buffer.
12717 (command_loop_1): Use read_key_sequence's remapping directly.
12719 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
12721 * dired.c (file_name_completion): Don't expand file name.
12722 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
12723 before checking file name handler.
12725 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
12726 they've been requested explicitly (bug#9591).
12728 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
12730 * keymap.c (Fsingle_key_description): Use make_specified_string
12731 instead of build_string to build string from push_key_description.
12734 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
12736 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
12737 This fixes a Y2038 bug on 64-bit hosts.
12738 * buffer.c (reset_buffer):
12739 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
12740 (Fclear_buffer_auto_save_failure):
12741 Use 0, not -1, to represent an unset failure time, since time_t
12742 might not be signed.
12744 Remove dependency on glibc malloc internals.
12745 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12746 Move back here from lisp.h, but with their new implementations.
12747 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
12748 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
12749 * charset.c (charset_table_init): New static var.
12750 (syms_of_charset): Use it instead of xmalloc. This removes a
12751 dependency on glibc malloc internals. See Eli Zaretskii's comment in
12752 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
12753 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12754 Move back to alloc.c.
12755 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
12756 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
12758 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
12760 * nsterm.m (windowDidResize): Call x_set_window_size only when
12761 ns_in_resize is true. Otherwise set pixelwidth/height and
12762 call change_frame_size (Bug#9628).
12764 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
12766 Port --enable-checking=all to Fedora 14 x86-64.
12767 * charset.c (syms_of_charset): Also account for glibc malloc's
12768 internal overhead when calculating the initial malloc maximum.
12770 Port --enable-checking=all to Fedora 14 x86.
12771 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12773 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
12774 (overrun_check_realloc, overrun_check_free):
12775 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
12776 That way, xmalloc returns a properly-aligned pointer even if
12777 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
12778 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
12779 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
12780 into account when calculating the initial malloc maximum.
12781 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12782 Move here from alloc.c, so that charset.c can use it too.
12783 Properly align; the old code wasn't right for common 32-bit hosts
12784 when configured with --enable-checking=all.
12785 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
12786 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
12788 2011-09-29 Eli Zaretskii <eliz@gnu.org>
12790 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
12793 2011-09-28 Eli Zaretskii <eliz@gnu.org>
12795 * xdisp.c (compute_display_string_end): If there's no display
12796 string at CHARPOS, return -1.
12798 * bidi.c (bidi_fetch_char): When compute_display_string_end
12799 returns a negative value, treat the character as a normal
12800 character not covered by a display string. (Bug#9624)
12802 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
12804 * lread.c (Fread_from_string): Fix typo in docstring.
12806 2011-09-27 Eli Zaretskii <eliz@gnu.org>
12808 * xdisp.c (handle_invisible_prop): If invisible text ends on a
12809 newline, reseat the iterator instead of bidi-iterating there one
12810 character at a time. (Bug#9610)
12811 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
12812 TO_CHARPOS if the bidi iterator is at base embedding level.
12814 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
12816 * lread.c (readevalloop): Use correct code for NBSP.
12817 (read1): Likewise. (Bug#9608)
12819 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
12821 * dbusbind.c (Fdbus_register_signal): When service is not
12822 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
12824 2011-09-25 Glenn Morris <rgm@gnu.org>
12826 * buffer.c (truncate-lines): Doc fix.
12828 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
12830 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
12831 (Fset_window_next_buffers): Doc fix.
12833 2011-09-24 Glenn Morris <rgm@gnu.org>
12835 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
12837 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
12839 Fix minor problems found by static checking.
12840 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
12841 * indent.c (Fvertical_motion): Fix == vs = typo.
12843 2011-09-24 Eli Zaretskii <eliz@gnu.org>
12845 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
12846 Default value is now t. Doc fix.
12848 * indent.c (Fvertical_motion): Compute and apply the overshoot
12849 logic when moving up, not only when moving down. Fix the
12850 confusing name and values of the it_overshoot_expected variable;
12851 logic changes accordingly. (Bug#9254) (Bug#9549)
12853 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
12854 CHARPOS is covered by a display string which includes newlines.
12855 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
12856 is covered by a display string with embedded newlines.
12858 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
12860 * dbusbind.c (Fdbus_register_signal): Add match rule to
12861 Vdbus_registered_objects_table. (Bug#9581)
12862 (Fdbus_register_method, Vdbus_registered_objects_table):
12865 2011-09-24 Jim Meyering <meyering@redhat.com>
12867 do not ignore write error for any output size
12868 The previous change was incomplete.
12869 While it makes emacs --batch detect the vast majority of stdout
12870 write failures, errors were still ignored whenever the output size is
12871 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
12872 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
12873 && echo FAIL: ignored write error
12874 FAIL: ignored write error
12875 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
12876 && echo FAIL: ignored write error
12877 FAIL: ignored write error
12878 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
12880 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
12882 * emacs.c (Fkill_emacs): In noninteractive mode exit
12883 non-successfully if a write error occurred on stdout. (Bug#9574)
12885 2011-09-21 Eli Zaretskii <eliz@gnu.org>
12887 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
12890 * dispextern.h (struct it): Update the comment documenting what
12893 2011-09-20 Eli Zaretskii <eliz@gnu.org>
12895 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
12896 a display string, extend search for cursor position to end of row.
12897 (find_row_edges): If the row ends in a newline from a display
12898 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
12899 Handle the case of a display string with multiple newlines.
12900 (Fcurrent_bidi_paragraph_direction): Fix search for previous
12901 non-empty line. Fixes confusing cursor motion with arrow keys at
12902 the beginning of a line that starts with whitespace.
12904 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
12906 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
12909 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
12911 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
12912 boolean (Bug#9154).
12914 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12916 * xdisp.c (display_line): Record maximum and minimum buffer
12917 positions even if no glyphs were produced (e.g., by a zero-width
12918 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
12919 buffer positions that will be removed from the glyph row because
12921 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
12922 column is beyond frame width: don't subtract 1 "pixel" when
12923 computing width of the stretch.
12924 (reseat_at_next_visible_line_start): Undo the change made on
12925 2011-09-17 that saved paragraph information and restored it after
12926 the call to `reseat'. (Bug#9545)
12928 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12930 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
12931 and turn window cursor on if cleared (Bug#9415).
12933 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
12935 * search.c (boyer_moore): Take unibyte characters from pattern
12936 literally. (Bug#9458)
12938 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12940 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
12942 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
12944 Fix minor problem found by static checking.
12945 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
12946 initialized, to pacify gcc -Wuninitialized.
12948 * fileio.c: Report proper errno when syscall falls.
12949 (Finsert_file_contents): Save and restore errno,
12950 so that report_file_error outputs the correct diagnostic.
12951 (Fwrite_region) [CLASH_DETECTION]: Likewise.
12953 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12955 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
12957 2011-09-17 Eli Zaretskii <eliz@gnu.org>
12959 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
12960 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
12962 2011-09-17 Eli Zaretskii <eliz@gnu.org>
12964 * xdisp.c (reseat_at_next_visible_line_start): Keep information
12965 about the current paragraph and restore it after the call to reseat.
12967 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
12968 (bidi_find_paragraph_start): Search back for paragraph beginning
12969 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
12970 (bidi_move_to_visually_next): Only trigger paragraph-related
12971 computations when the last character is a newline or at EOB, not
12972 just any NEUTRAL_B. (Bug#9470)
12974 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
12975 truncated lines if point is covered by a display string. (Bug#9524)
12977 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
12979 * xselect.c: Relax test for outgoing X longs (Bug#9498).
12980 (cons_to_x_long): New function.
12981 (lisp_data_to_selection_data): Use it. Correct the test for
12982 short-versus-long data; it was negated. Break out of vector
12983 loop, for efficiency, when a long datum is discovered.
12985 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
12987 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
12989 2011-09-16 Eli Zaretskii <eliz@gnu.org>
12991 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
12992 GCC PR/17406) by declaring this function with external scope.
12994 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
12996 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
12997 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
12999 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
13001 * editfns.c (Fformat): Correctly handle text properties on "%%".
13003 2011-09-15 Eli Zaretskii <eliz@gnu.org>
13005 * xterm.c (x_draw_composite_glyph_string_foreground):
13006 * w32term.c (x_draw_composite_glyph_string_foreground):
13007 * term.c (encode_terminal_code):
13008 * composite.c (composition_update_it, get_composition_id):
13009 * xdisp.c (get_next_display_element)
13010 (fill_composite_glyph_string): Add comments about special meaning
13011 of TAB characters in a composition.
13013 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13015 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
13016 This occurs when processing a multibyte format.
13017 Problem reported by Wolfgang Jenker.
13019 2011-09-15 Johan Bockgård <bojohan@gnu.org>
13021 * xdisp.c (try_cursor_movement): Only check for exact match if
13022 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
13024 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13026 Remove unused external symbols.
13027 * dispextern.h (calc_pixel_width_or_height): Remove decl.
13028 * xdisp.c (calc_pixel_width_or_height): Now static.
13029 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
13030 * indent.c (check_display_width):
13031 * w32term.c: Fix comment to match code.
13032 * xterm.c, xterm.h (x_catching_errors): Remove.
13034 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13036 * xselect.c: Use signed conversions more consistently (Bug#9498).
13037 (selection_data_to_lisp_data): Assume incoming selection data are
13038 signed integers, not unsigned. This is to be consistent with
13039 outgoing selection data, which was modified to use signed integers
13040 in as part of the fix to Bug#9196 in response to Jan D.'s comment
13041 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
13042 expects long, not unsigned long.
13044 2011-09-14 Eli Zaretskii <eliz@gnu.org>
13046 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
13047 computation of loop end. Reported by Johan Bockgård
13050 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
13052 * frame.c (Fother_visible_frames_p): Function deleted.
13054 2011-09-12 Eli Zaretskii <eliz@gnu.org>
13056 * indent.c (compute_motion): Process display vector front to back
13057 rather than the other way around. (Bug#2496)
13059 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
13061 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
13063 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
13065 * minibuf.c (Fread_from_minibuffer): Doc fix.
13067 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13069 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
13070 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
13072 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
13074 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
13075 value for non-existent files.
13077 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13079 * fileio.c (Finsert_file_contents): If the file cannot be opened,
13080 set its "size" to -1. This will set the modtime_size field of
13081 the corresponding buffer to -1, which is what
13082 verify-visited-file-modtime expects for files that do not exist.
13085 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
13087 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
13089 * lisp.h: ... from here. push_key_description is no longer
13090 defined in keyboard.c, so its declaration should not be in
13091 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
13092 logically belongs with push_key_description.
13094 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
13096 * buffer.h: Include <sys/types.h> instead of <time.h>.
13097 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
13098 Problem reported by Herbert J. Skuhra.
13100 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
13102 * xml.c (parse_region): Make the parsing work for
13103 non-comment-starting XML files again (bug#9144).
13105 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
13107 * image.c (gif_load): Fix calculation of bottom and right corner.
13110 2011-09-10 Eli Zaretskii <eliz@gnu.org>
13112 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
13113 redisplay in small windows.
13115 2011-09-09 Eli Zaretskii <eliz@gnu.org>
13117 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
13119 2011-09-08 Martin Rudalics <rudalics@gmx.at>
13121 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
13122 Operate on live windows only.
13124 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
13126 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
13128 2011-09-07 Eli Zaretskii <eliz@gnu.org>
13130 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
13131 only under bidi iteration.
13133 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
13135 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
13137 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13139 isnan: Fix porting problem to Solaris 10 with bundled gcc.
13140 Without this fix, the command to link temacs failed due to an
13141 undefined symbol __builtin_isnan. This is because
13142 /usr/include/iso/math_c99.h #defines isnan(x) to
13143 __builtin_isnan(x), but the bundled gcc, which identifies itself
13144 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
13146 * floatfns.c (isnan): #undef, and then #define to a clone of
13148 (Fisnan): Always define, since it's always available now.
13149 (syms_of_floatfns): Always define isnan at the Lisp level.
13151 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13153 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
13155 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13157 * fileio.c: Fix bugs with large file offsets (Bug#9428).
13158 The previous code assumed that file offsets (off_t values) fit in
13159 EMACS_INT variables, which is not true on typical 32-bit hosts.
13160 The code messed up by falsely reporting buffer overflow in cases
13161 such as (insert-file-contents "big" nil 1 2) into an empty buffer
13162 when "big" contains more than 2**29 bytes, even though this
13163 inserts just one byte and does not overflow the buffer.
13164 (Finsert_file_contents): Store file offsets as off_t
13165 values, not as EMACS_INT values. Check for overflow when
13166 converting between EMACS_INT and off_t. When checking for
13167 buffer overflow or for overlap, take the offsets into account.
13168 Don't use EMACS_INT for small values where int suffices.
13169 When checking for overlap, fix a typo: ZV was used where
13170 ZV_BYTE was intended.
13171 (Fwrite_region): Don't assume off_t fits into 'long'.
13172 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
13174 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
13176 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
13178 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13180 sprintf-related integer and memory overflow issues (Bug#9412).
13182 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
13183 (esprintf, exprintf, evxprintf): New functions.
13184 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
13185 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
13186 (modify_event_symbol): Do not assume that the length of
13187 name_alist_or_stem is safe to alloca and fits in int.
13188 (Fexecute_extended_command): Likewise for function name and binding.
13189 (Frecursion_depth): Wrap around reliably on integer overflow.
13190 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
13191 since some callers pass EMACS_INT values.
13192 (Fsingle_key_description): Don't crash if symbol name contains more
13193 than MAX_ALLOCA bytes.
13194 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
13195 (get_minibuffer): Arg is now EMACS_INT, not int.
13196 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
13197 (esprintf, exprintf, evxprintf): New decls.
13198 * window.h (command_loop_level, minibuf_level): Reflect API changes.
13200 * dbusbind.c (signature_cat): New function.
13201 (xd_signature, Fdbus_register_signal):
13202 Do not overrun buffer; instead, report string overflow.
13204 * dispnew.c (add_window_display_history): Don't overrun buffer.
13205 Truncate instead; this is OK since it's just a log.
13207 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
13208 even if the time zone offset is outlandishly large.
13209 Don't mishandle offset == INT_MIN.
13211 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
13212 when creating daemon; the previous buffer-overflow check was incorrect.
13214 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
13215 which has the guts of the old verror function.
13217 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
13218 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
13220 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
13221 (font_unparse_xlfd): Don't blindly alloca long strings.
13222 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
13223 fits in int, when using sprintf. Use single snprintf to count
13224 length of string rather than counting it via multiple sprintfs;
13225 that's simpler and more reliable.
13226 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
13227 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
13228 sprintf, in case result does not fit in int.
13230 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
13231 (fontset_from_font): Print it.
13233 * frame.c (tty_frame_count): Now printmax_t, not int.
13234 (make_terminal_frame, set_term_frame_name): Print it.
13235 (x_report_frame_params): In X, window IDs are unsigned long,
13236 not signed long, so print them as unsigned.
13237 (validate_x_resource_name): Check for implausibly long names,
13238 and don't assume name length fits in 'int'.
13239 (x_get_resource_string): Don't blindly alloca invocation name;
13240 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
13243 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
13244 (xg_check_special_colors, xg_set_geometry):
13245 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
13247 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
13248 Use esprintf, not sprintf, in case result does not fit in int.
13250 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13251 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
13252 it as a large positive number.
13253 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
13254 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13256 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
13257 in case result does not fit in int.
13259 * print.c (float_to_string): Detect width overflow more reliably.
13260 (print_object): Make sprintf buffer a bit bigger, to avoid potential
13261 buffer overrun. Don't assume list length fits in 'int'. Treat
13262 print length of 0 as 0, not as infinity; to be consistent with other
13263 uses of print length in this function. Don't overflow print length
13264 index. Don't assume hash table size fits in 'long', or that
13265 vectorlike size fits in 'unsigned long'.
13267 * process.c (make_process): Use printmax_t, not int, to format
13268 process-name gensyms.
13270 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
13272 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
13273 to avoid potential buffer overrun.
13275 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
13276 if X resource line is longer than 512 bytes.
13278 * xfns.c (x_window): Make sprintf buffer a bit bigger
13279 to avoid potential buffer overrun.
13281 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
13283 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
13285 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13287 Integer overflow fixes for scrolling, etc.
13288 Without these, Emacs silently mishandles large integers sometimes.
13289 For example, "C-u 4294967297 M-x recenter" was treated as if
13290 it were "C-u 1 M-x recenter" on a typical 64-bit host.
13292 * xdisp.c (try_window_id): Check Emacs fixnum range before
13293 converting to 'int'.
13295 * window.c (window_scroll_line_based, Frecenter):
13296 Check that an Emacs fixnum is in range before assigning it to 'int'.
13297 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
13298 values converted from Emacs fixnums.
13299 (Frecenter): Don't wrap around a line count if it is out of 'int'
13300 range; instead, treat it as an extreme value.
13301 (Fset_window_configuration, compare_window_configurations):
13302 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
13304 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
13305 that can exceed INT_MAX. Check that EMACS_INT value is in range
13306 before assigning it to the (possibly-narrower) index.
13307 (match_limit): Don't assume that a fixnum can fit in 'int'.
13309 * print.c (print_object): Use ptrdiff_t, not int, for index that can
13312 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
13313 (Fvertical_motion): Don't wrap around LINES values that don't fit
13314 in 'int'. Instead, treat them as extreme values. This is good
13315 enough for windows, which can't have more than INT_MAX lines anyway.
13317 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
13319 * Require libxml/parser.h to avoid compilation warning.
13321 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
13323 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
13324 since this reportedly can destroy thread storage.
13326 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
13328 * syntax.c (find_defun_start): Update all cache variables if
13329 exiting early (Bug#9401).
13331 2011-08-30 Eli Zaretskii <eliz@gnu.org>
13333 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
13335 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
13336 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
13337 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
13339 * term.c (tty_append_glyph): New function.
13340 (produce_stretch_glyph): Static function and its prototype deleted.
13342 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
13345 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
13347 * image.c (parse_image_spec): Check for nonnegative, not for positive,
13348 when checking :margin (Bug#9390).
13349 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
13350 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
13351 so that the name doesn't mislead. All uses changed.
13353 2011-08-28 Johan Bockgård <bojohan@gnu.org>
13355 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
13358 2011-08-27 Eli Zaretskii <eliz@gnu.org>
13360 * xdisp.c (move_it_to): Don't bail out early when reaching
13361 position beyond to_charpos, if we are scanning backwards.
13362 (move_it_vertically_backward): When DY == 0, make sure we get to
13363 the first character in the line after the newline.
13365 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
13367 * ccl.c: Improve and simplify overflow checking (Bug#9196).
13368 (ccl_driver): Do not generate an out-of-range pointer.
13369 (Fccl_execute_on_string): Remove unnecessary check for
13370 integer overflow, noted by Stefan Monnier in
13371 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
13372 Remove a FIXME that didn't need fixing.
13373 Simplify the newly-introduced buffer reallocation code.
13375 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
13377 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
13379 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
13381 Integer and memory overflow issues (Bug#9196).
13383 * doc.c (get_doc_string): Rework so that
13384 get_doc_string_buffer_size is the actual buffer size, rather than
13385 being 1 less than the actual buffer size; this makes xpalloc more
13388 * image.c (x_allocate_bitmap_record, cache_image):
13389 * xselect.c (Fx_register_dnd_atom):
13390 Simplify previous changes by using xpalloc.
13392 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
13393 since either will do and ptrdiff_t is convenient with xpalloc.
13395 * charset.c (charset_table_size)
13396 (struct charset_sort_data.priority): Now ptrdiff_t.
13397 (charset_compare): Don't overflow if priorities differ greatly.
13398 (Fsort_charsets): Don't assume list length fits in int.
13399 Check for size-calculation overflow when allocating sort data.
13400 (syms_of_charset): Allocate an initial charset table that is
13401 just under 64 KiB, to avoid problems with glibc malloc and mmap.
13403 * cmds.c (internal_self_insert): Check for size-calculation overflow.
13405 * composite.h (struct composition.glyph_len): Now int, not unsigned.
13406 The actual value is always <= INT_MAX, and leaving it unsigned made
13407 overflow checking harder.

13421 (revalidate_region_cache, know_region_cache, region_cache_forward)
13422 (region_cache_backward, pp_cache):
13423 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
13424 so that ptrdiff_t * can be passed to xpalloc.

13443 Don't update size of array until after memory allocation succeeds,
13444 because xmalloc/xrealloc may not return.
13445 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
13446 now that we have proper integer overflow checking.

13450 * callproc.c (Fcall_process): Check for size overflow when

13457 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.

13497 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
13499 * emacs.c (main): Do not reallocate argv, since there is a null at
13500 the end that can be overwritten, and this way there's no need to
13501 worry about size-calculation overflow.
13502 (sort_args): Check for size-calculation overflow.
13504 * eval.c (init_eval_once, grow_specpdl): Don't update size until

13511 (x_set_alpha): Do not assume XINT fits in int.
13513 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
13514 This is for the members text_lines, text_cols, total_lines, total_cols,
13515 where the system imposes an 'int' limit.

13524 Check for size-calculation overflow.
13525 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
13526 do, as we prefer signed integers.

13533 * gtkutil.h: Change prototypes to match the above.
13535 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these

13631 (X_LONG_MIN): New macros.
13632 Use them to make the following changes clearer.
13633 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.

13636 (SELECTION_QUANTUM): Remove, replacing with ...
13637 (selection_quantum): ... new function, which avoids overflow.
13639 (struct selection_data.size): Now ptrdiff_t, not int, to avoid

13657 Don't store size until memory allocation succeeds.
13658 (x_get_window_property): Plug memory leak on memory exhaustion.
13659 Don't double-block input; malloc is safe here. Don't assume 2**34
13660 - 4 fits in unsigned long. Add an xassert to check
13661 XGetWindowProperty overflow. Be more careful about overflow
13662 calculations, and distinguish size from memory overflow better.

13706 * lisp.h (hash_lookup, hash_put):
13707 * minibuf.c (Ftest_completion):

13753 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
13754 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
13755 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
13756 length, not size_t. Use ptrdiff_t for index, not int.
13757 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
13758 possibility of integer overflow.

13786 Prefer int to unsigned where either will do.
13787 (tiff_handler): New function, combining the cores of the
13788 old tiff_error_handler and tiff_warning_handler.
13789 This function is rewritten to use vsnprintf and thereby avoid
13790 stack buffer overflows. It uses only the features of vsnprintf
13791 that are common to both POSIX and native Microsoft.
13792 (tiff_error_handler, tiff_warning_handler): Use it.
13793 (tiff_load, gif_load, imagemagick_load_image):
13794 Don't assume :index value fits in 'int'.

13834 2011-08-24 Eli Zaretskii <eliz@gnu.org>
13836 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
13837 buffers, return left-to-right.
13838 (set_cursor_from_row): Consider candidate row a win if its glyph
13839 represents a newline and point is on that newline. Fixes cursor
13840 positioning on the newline at EOL of R2L text within L2R
13841 paragraph, and vice versa.
13842 (try_cursor_movement): Check continued rows, in addition to
13843 continuation rows. Fixes unwarranted scroll when point enters a
13844 continued line of R2L text within an L2R paragraph, or vice versa.
13845 (cursor_row_p): Consider the case of point being equal to
13846 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
13847 from the end of a short line to the beginning of a continued line
13848 of R2L text within L2R paragraph.
13849 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

13867 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
13868 extra slot even if the purpose is char-code-property-table.
13870 2011-08-23 Eli Zaretskii <eliz@gnu.org>
13872 * xdisp.c (redisplay_window): When computing centering_position,
13873 account for the height of the header line. (Bug#8874)
13875 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
13876 instead of CHAR_TO_BYTE. Fixes a crash when a completion
13877 candidate is selected by the mouse, and that candidate has a
13878 composed character under the mouse.
13880 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
13881 coordinates reported by pos-visible-in-window-p for a composed
13882 character in column zero.
13884 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
13886 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
13888 2011-08-22 Eli Zaretskii <eliz@gnu.org>
13890 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
13891 consider it a hit if to_charpos is anywhere in the range of the
13892 composed buffer positions.
13894 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
13896 * image.c (gif_load): Don't assume that each subimage has the same
13897 dimensions as the base image. Handle disposal method that is
13898 "undefined" by the gif spec (Bug#9335).
13900 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
13902 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
13903 (Fcondition_case): Document `debug' symbol in error handler.
13905 2011-08-19 Eli Zaretskii <eliz@gnu.org>
13907 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
13908 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
13909 from an Org mode buffer to a Speedbar frame.
13911 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
13912 a composition, take its buffer position from IT->cmp_it.charpos.
13913 Fixes cursor positioning at the beginning of a line that begins
13914 with a composed character.
13916 2011-08-18 Eli Zaretskii <eliz@gnu.org>
13918 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
13919 character bidirectional type, use STRONG_L instead. Fixes crashes
13920 in a buffer produced by `describe-categories'.
13922 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
13923 members before the level stack, so they would be saved and
13924 restored when copying iterator state. Fixes incorrect reordering
13925 around TABs covered by display properties.
13927 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
13929 * process.c (Fnetwork_interface_list): Correctly determine buffer size.
13931 2011-08-17 Chong Yidong <cyd@stupidchicken.com>
13933 * eval.c (internal_condition_case, internal_condition_case_1)
13934 (internal_condition_case_2, internal_condition_case_n):
13935 Remove unnecessary aborts (Bug#9081).
13937 2011-08-17 Eli Zaretskii <eliz@gnu.org>
13939 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
13940 has no `load' handler, try opening the file locally. (Bug#9311)
13942 2011-08-16 Ken Brown <kbrown@cornell.edu>
13944 * gmalloc.c: Expand comment.
13946 2011-08-16 Eli Zaretskii <eliz@gnu.org>

13994 * process.c (create_process): Call setup_process_coding_systems
13995 after the pid of the process is set to -1 (Bug#8162).
13997 2011-08-14 Eli Zaretskii <eliz@gnu.org>
13999 * xdisp.c (move_it_in_display_line_to): Don't invoke
14000 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
14001 ppos_it. Fixes vertical cursor motion when line beginning is
14002 covered by an image. (Bug#9296)
14004 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
14006 * nsterm.h (ns_run_ascript): Declare.

14010 (ns_run_ascript): New function.
14011 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
14012 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
14013 the event loop. Get status from as_status (Bug#7276).
14015 * nsterm.m (sendEvent): If event is NSApplicationDefined and
14016 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
14017 the event loop (Bug#7276).
14019 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
14021 * gnutls.c (QCgnutls_bootprop_priority)
14022 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
14023 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
14024 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
14025 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)

14043 (Fnetwork_interface_list): Allocate in increments of bytes instead
14044 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
14045 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
14047 (struct ifflag_def): notrailers is smart on OSX.
14048 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
14049 Get hardware address with getifaddrs if available.
14051 2011-08-12 Eli Zaretskii <eliz@gnu.org>
14053 * xdisp.c (iterate_out_of_display_property): xassert that
14054 IT->position is set to within IT->object's boundaries. Break from
14055 the loop as soon as EOB is reached; avoids infloops in redisplay
14056 when IT->position is set up wrongly due to some bug.
14057 Set IT->current to match the bidi iterator unconditionally.
14058 (push_display_prop): Allow GET_FROM_STRING as IT->method on
14059 entry. Force push_it to save on the stack the current
14060 buffer/string position, to be restored by pop_it. Fix flags in
14061 the iterator structure wrt the object coming from a display
14062 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
14063 properties. (Bug#9284)
14065 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
14067 * fontset.c (fontset_get_font_group): Add proper type checks.

14097 2011-08-07 Juri Linkov <juri@jurta.org>
14099 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
14100 to show the arg `TIME' instead of `TIMEVAL'.
14102 2011-08-06 Eli Zaretskii <eliz@gnu.org>
14104 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
14105 display property strides EOL and includes a newline, as in
14106 longlines-mode. (Bug#9254)
14107 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
14108 word-wrap under bidirectional display. (Bug#9224)
14110 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
14111 is non-zero, even if the data buffer is NULL. Fixes a crash in
14112 vertical-motion with longlines-mode. (Bug#9254)
14114 2011-08-05 Eli Zaretskii <eliz@gnu.org>
14116 * bidi.c <bidi_cache_total_alloc>: Now static.

14119 * xdisp.c (display_line): Release buffer allocated for shelved bidi
14122 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
14123 amount allocated this far in `bidi_cache_total_alloc'.
14124 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
14125 non-zero, only free the data buffer without restoring the cache
14126 contents. All callers changed.
14128 * dispextern.h (bidi_unshelve_cache): Update prototype.
14130 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)

14133 to xfree to an equivalent call to bidi_unshelve_cache.
14134 (move_it_in_display_line_to): Fix logic of returning
14135 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
14137 2011-08-05 Eli Zaretskii <eliz@gnu.org>
14139 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that

14190 * bidi.c (bidi_fetch_char): Accept an additional argument
14191 DISP_PROP_P, and pass it to compute_display_string_pos.
14192 Only handle text covered by a display string if DISP_PROP_P is returned
14193 non-zero. All callers of bidi_fetch_char changed.
14195 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>

14227 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
14228 This is needed if max-image-size is a floating-point number.

14280 Without this fix, if a signal arrives just after memory fills up,
14281 'malloc' might be invoked reentrantly.
14283 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
14284 In other words, assume that every image size is allowed, on non-X
14285 hosts. This assumption is probably wrong, but it lets Emacs compile.

14309 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
14310 (bidi_find_other_level_edge):
14311 Use ptrdiff_t instead of EMACS_INT where either will do.
14312 This works better on 32-bit hosts configured --with-wide-int.
14313 (bidi_cache_ensure_space): Check for size-calculation overflow.
14314 Use % rather than repeated addition, for better worst-case speed.
14315 Don't set bidi_cache_size until after xrealloc returns, because it
14317 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
14318 (bidi_cache_ensure_space): Also check that the bidi cache size
14319 does not exceed that of the largest Lisp string or buffer. See Eli
14320 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
14322 * alloc.c (__malloc_size_t): Remove.
14323 All uses replaced by size_t. See Andreas Schwab's note
14324 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
14326 * image.c: Improve checking for integer overflow.
14327 (check_image_size): Assume that f is nonnull, since
14328 it is always nonnull in practice. This is one less thing to
14329 worry about when checking for integer overflow later.
14330 (x_check_image_size): New function, which checks for integer
14331 overflow issues inside X.
14332 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
14333 This removes the need for a memory_full check.
14334 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
14335 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
14336 (xbm_read_bitmap_data): Change locals back to 'int', since
14337 their values must fit in 'int'.
14338 (xpm_load_image, png_load, tiff_load):
14339 Invoke x_create_x_image_and_pixmap earlier,
14340 to avoid much needless work if the image is too large.
14341 (tiff_load): Treat overly large images as if
14342 x_create_x_image_and_pixmap failed, not as malloc failures.
14343 (gs_load): Use x_check_image_size.
14345 * gtkutil.c: Omit integer casts.
14346 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
14347 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
14349 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
14351 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
14352 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
14353 would wrongly return t on a 64-bit host.
14355 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
14356 The plain *_OVERFLOW macros run afoul of GCC bug 49705
14357 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
14358 and therefore cause GCC to emit a bogus diagnostic in some cases.
14360 * image.c: Integer signedness and overflow and related fixes.
14361 This is not an exhaustive set of fixes, but it's time to
14362 record what I've got.
14363 (lookup_pixel_color, check_image_size): Remove redundant decls.
14364 (check_image_size): Don't assume that arbitrary EMACS_INT values
14365 fit in 'int', or that arbitrary 'double' values fit in 'int'.
14366 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
14367 (tiff_load, imagemagick_load_image):
14368 Check for overflow in size calculations.
14369 (x_create_x_image_and_pixmap): Remove unnecessary test for
14370 xmalloc returning NULL; that can't happen.
14371 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
14372 (xpm_color_bucket): Use better integer hashing function.
14373 (xpm_cache_color): Don't possibly over-allocate memory.
14374 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
14375 (gif_memory_source):
14376 Use ptrdiff_t, not int or size_t, to record sizes.
14377 (png_load): Don't assume values greater than 2**31 fit in 'int'.
14378 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
14379 either works, as we prefer signed integers.
14380 (tiff_read_from_memory, tiff_write_from_memory):
14381 Return tsize_t, not size_t, since that's what the TIFF API wants.
14382 (tiff_read_from_memory): Don't fail simply because the read would
14383 go past EOF; instead, return a short read.
14384 (tiff_load): Omit no-longer-needed casts.
14385 (Fimagemagick_types): Don't assume size fits into 'int'.
14387 Improve hashing quality when configured --with-wide-int.
14388 * fns.c (hash_string): New function, taken from sxhash_string.
14389 Do not discard information about ASCII character case; this
14390 discarding is no longer needed.
14391 (sxhash-string): Use it. Change sig to match it. Caller changed.
14392 * lisp.h: Declare it.
14393 * lread.c (hash_string): Remove, since we now use fns.c's version.
14394 The fns.c version returns a wider integer if --with-wide-int is
14395 specified, so this should help the quality of the hashing a bit.
14397 * emacs.c: Integer overflow minor fix.
14398 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
14399 Define only if GNU_LINUX.
14400 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
14402 * dispnew.c: Integer signedness and overflow fixes.
14403 Remove unnecessary forward decls, that were a maintenance hassle.
14404 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
14406 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
14407 (scrolling_window): Use ptrdiff_t, not int, for byte count.
14408 (prepare_desired_row, line_draw_cost):
14409 Use int, not unsigned, where either works.
14410 (save_current_matrix, restore_current_matrix):
14411 Use ptrdiff_t, not size_t, where either works.
14412 (init_display): Check for overflow more accurately, and without
14413 relying on undefined behavior.
14415 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
14416 Remove, replacing with the new symbols in lisp.h. All uses changed.
14417 * fileio.c (make_temp_name):
14418 * filelock.c (lock_file_1, lock_file):
14419 * xdisp.c (message_dolog):
14420 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
14421 Use pMd etc. instead.
14422 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
14423 replacing the pWIDE etc. symbols removed from editfns.c.
14425 * keyboard.h (num_input_events): Now uintmax_t.
14426 This is (very slightly) less likely to mess up due to wraparound.
14429 * buffer.c: Integer signedness fixes.
14430 (alloc_buffer_text, enlarge_buffer_text):
14431 Use ptrdiff_t rather than size_t when either will do, as we prefer
14434 * alloc.c: Integer signedness and overflow fixes.
14435 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
14436 (__malloc_size_t): Default to size_t, not to int.
14437 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
14438 (Fgarbage_collect, mark_object_loop_halt, mark_object):
14439 Prefer ptrdiff_t to size_t when either would do, as we prefer
14441 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
14442 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
14443 Now const. Initialize with values that are in range even if char
14445 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
14446 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
14447 These functions do the right thing with sizes > 2**32.
14448 (check_depth): Now ptrdiff_t, not int.
14449 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
14450 Adjust to new way of storing sizes. Check for size overflow bugs
14452 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
14453 slightly wrong anyway, as it missed one instance of
14454 XMALLOC_OVERRUN_CHECK_OVERHEAD.
14455 (refill_memory_reserve): Omit needless cast to size_t.
14456 (mark_object_loop_halt): Mark as externally visible.
14458 * xselect.c: Integer signedness and overflow fixes.
14459 (Fx_register_dnd_atom, x_handle_dnd_message):
14460 Use ptrdiff_t, not size_t, since we prefer signed.
14461 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
14462 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
14463 x_dnd_atoms_size and x_dnd_atoms_length.
14465 * doprnt.c: Prefer signed to unsigned when either works.
14467 * doprnt.c (doprnt):
14469 * xdisp.c (vmessage):
14470 Use ptrdiff_t, not size_t, when using or implementing doprnt,
14471 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
14472 prefer signed arithmetic to avoid comparison confusion.
14473 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
14474 but is a bit tricky.
14476 Assume freestanding C89 headers, string.h, stdlib.h.
14477 * data.c, doprnt.c, floatfns.c, print.c:
14478 Include float.h unconditionally.
14479 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
14480 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
14481 * regex.c: Likewise for stddef.h, string.h.
14482 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
14483 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
14484 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
14485 (STDC_HEADERS): Remove obsolete defines.
14486 * sysdep.c: Include limits.h unconditionally.
14488 Assume support for memcmp, memcpy, memmove, memset.
14489 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
14490 * regex.c (memcmp, memcpy):
14491 Remove; we assume C89 now.
14493 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
14494 (__malloc_safe_bcopy): Remove; no longer needed.
14496 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
14497 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
14498 well either way, and we prefer signed to unsigned.
14500 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
14502 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
14503 closes the connection while we're reading (bug#9182).
14505 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
14507 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
14508 are specified (Bug#9168).
14510 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
14512 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
14513 Found by GCC static checking and --with-wide-int on a 32-bit host.
14515 2011-07-25 Eli Zaretskii <eliz@gnu.org>
14517 * xdisp.c (compute_display_string_pos): Fix logic of caching
14518 previous display string position. Initialize cached_prev_pos to
14519 -1. Fixes slow-down at the beginning of a buffer.
14521 2011-07-24 Eli Zaretskii <eliz@gnu.org>
14523 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
14524 for attrs[LFACE_FONTSET_INDEX].
14526 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
14528 * xml.c (parse_region): Remove unused local
14529 that was recently introduced.
14531 2011-07-23 Eli Zaretskii <eliz@gnu.org>
14533 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
14534 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
14536 * xdisp.c (move_it_in_display_line_to): Record the best matching
14537 position for TO_CHARPOS while scanning the line, and restore it on
14538 exit if none of the characters scanned was an exact match.
14539 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
14540 when exact match is impossible due to invisible text, and the
14541 lines are truncated.
14543 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
14545 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
14548 2011-07-22 Eli Zaretskii <eliz@gnu.org>
14550 Fix a significant slow-down of cursor motion with C-n, C-p,
14551 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
14552 auto-repeat under bidi redisplay in fontified buffers.
14553 * xdisp.c (compute_stop_pos_backwards): New function.
14554 (next_element_from_buffer): Call compute_stop_pos_backwards to
14555 find a suitable prev_stop when we find ourselves before
14557 (reseat): Don't look for prev_stop, as that could mean a very long
14559 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
14560 <cached_disp_overlay_modiff>: Cache for last found display string
14562 (compute_display_string_pos): Return the cached position if asked
14563 about the same buffer in the same area of character positions, and
14564 the buffer wasn't changed since the time the display string
14565 position was cached.
14567 2011-07-22 Eli Zaretskii <eliz@gnu.org>
14569 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
14570 is an integer, which is important for empty lines. (Bug#9149)
14572 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
14574 * frame.c (Fmodify_frame_parameters): In tty case, update the
14575 default face if necessary (Bug#4238).
14577 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
14579 * editfns.c (Fstring_to_char): No need to explain what a character
14580 is in the docstring (Bug#6576).
14582 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
14584 * xml.c (parse_region): Make sure we always return a tree.
14586 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
14588 * xml.c (parse_region): If a document contains only comments,
14591 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
14593 * xml.c (make_dom): Return comments, too.
14595 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
14598 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
14599 and the surrounding thread.
14600 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
14601 rather than fgets, and retry after EINTR. Otherwise, 'emacs
14602 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
14604 * s/openbsd.h (BROKEN_SIGIO): Define.
14605 * unexelf.c (unexec) [__OpenBSD__]:
14606 Don't update the .mdebug section of the Alpha COFF symbol table.
14608 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14610 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
14613 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
14615 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
14616 This fixes some race conditions on the permissions of any newly
14619 * alloc.c (valid_pointer_p): Use pipe, not open.
14620 This fixes some permissions issues when debugging.
14622 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
14623 If fchown fails to set both uid and gid, try to set just gid,
14624 as that is sometimes allowed. Adjust the file's mode to eliminate
14625 setuid or setgid bits that are inappropriate if fchown fails.
14627 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
14629 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
14630 to compare Lisp_Objects.
14631 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
14632 global_gnutls_log_level, don't mistake it for a Lisp_Object.
14633 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
14635 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
14637 * lread.c (read_integer): Unread even EOF character.
14638 (read1): Likewise. Properly record start position of symbol.
14640 * lread.c (read1): Read `#:' as empty uninterned symbol if no
14641 symbol character follows.
14643 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
14645 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
14646 This works around a problem with the previous change to Fcopy_file.
14647 Recent glibc declares fchown with __attribute__((warn_unused_result)),
14648 and without this change, GCC might complain about discarding
14649 fchown's return value.
14651 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
14653 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
14655 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
14657 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
14659 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
14661 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
14662 it's used from the C level.
14664 * process.c: Use the same condition for POLL_FOR_INPUT in both
14665 keyboard.c and process.c (bug#1858).
14667 2011-07-09 Lawrence Mitchell <wence@gmx.li>
14669 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
14670 (Fgnutls_boot): Use it.
14672 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
14674 * doc.c (Fsubstitute_command_keys): Revert last change.
14676 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
14678 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
14679 quotes the next character, and doesn't affect other longer
14680 sequences (bug#8935).
14682 * lread.c (syms_of_lread): Clarify that is isn't only
14683 `eval-buffer' and `eval-defun' that's affected by
14684 `lexical-binding' (bug#8460).
14686 2011-07-15 Eli Zaretskii <eliz@gnu.org>
14688 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
14689 bidi redisplay when a line includes both an image and is truncated.
14691 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
14693 Fix minor problems found by static checking.
14694 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
14695 (elsz): Now a signed constant, not a size_t var. We prefer signed
14696 types to unsigned, to avoid integer comparison confusion. Without
14697 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
14698 "cannot optimize loop, the loop counter may overflow", a symptom
14700 * indent.c (Fvertical_motion): Mark locals as initialized.
14701 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
14703 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
14705 * search.c (Fre_search_backward): Mention `case-fold-search' in
14706 all the re_search_* functions (bug#8138).
14708 * keyboard.c (Fopen_dribble_file): Document when the file is
14711 2011-07-14 Eli Zaretskii <eliz@gnu.org>
14713 * bidi.c (bidi_dump_cached_states): Fix format of displaying
14716 Support bidi reordering of display and overlay strings.
14717 * xdisp.c (compute_display_string_pos)
14718 (compute_display_string_end): Accept additional argument STRING.
14719 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
14720 (reseat_to_string): Initialize bidi_it->string.s and
14721 bidi_it->string.schars.
14722 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
14723 NULL (avoids a crash in bidi_paragraph_init).
14724 Initialize itb.string.lstring.
14725 (init_iterator): Call bidi_init_it only of a valid
14726 buffer position was specified. Initialize paragraph_embedding to
14728 (reseat_to_string): Initialize the bidi iterator.
14729 (display_string): If we need to ignore text properties of
14730 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
14731 original value of -1 will not work with bidi.)
14732 (compute_display_string_pos): First arg is now struct
14733 `text_pos *'; all callers changed. Support display properties on
14735 (compute_display_string_end): Support display properties on Lisp
14737 (init_iterator, reseat_1, reseat_to_string): Initialize the
14738 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
14739 when iterating on a string not from display properties).
14740 (compute_display_string_pos, compute_display_string_end):
14741 Fix calculation of the object to scan. Fixes an error when using
14743 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
14744 base_level_stop; instead, set base_level_stop to BEGV.
14745 Fixes crashes in vertical-motion.
14746 (next_element_from_buffer): Improve commentary for when
14747 the iterator is before prev_stop.
14748 (init_iterator): Initialize bidi_p from the default value of
14749 bidi-display-reordering, not from buffer-local value. Use the
14750 buffer-local value only if initializing for buffer iteration.

15223 * alloc.c (mark_buffer):
15224 * buffer.c (reset_buffer_local_variables, Fbuffer_local_variables)
15225 (clone_per_buffer_values): Don't assume that

15227 This isn't true in general, and it's particularly not true
15228 if Emacs is configured with --with-wide-int.
15229 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
15230 New macros, used in the buffer.c change.

15266 Random fixes. E.g., (random) never returned negative values.
15267 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
15268 subseconds part to the entropy, as that's a bit more random.
15269 Prefer signed to unsigned, since the signedness doesn't matter and
15270 in general we prefer signed. When given a limit, use a
15271 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
15272 latter isn't right if USE_2_TAGS_FOR_INTS.
15273 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
15274 not 0..VALMASK. Don't discard "excess" bits that random () returns.

15278 * textprop.c (text_property_stickiness):
15279 Obey Vtext_property_default_nonsticky.

15286 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
15287 This is more efficient than Ffile_directory_p and avoids a minor race.
15289 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
15291 * buffer.c (Foverlay_put): Say what the return value is
15294 * fileio.c (barf_or_query_if_file_exists): Check first if the file
15295 is a directory before asking whether to use the file name
15297 (barf_or_query_if_file_exists): Make the "File is a directory"
15298 error be more correct.
15300 * fns.c (Frequire): Remove the mention of the .gz files, since
15301 that's installation-specific, but keep the mention of
15302 `get-load-suffixes'.

15314 Qgnutls_bootprop_verify_error (which is no longer used).
15316 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
15317 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
15318 Also (re)move comments that are misplaced or no longer relevant.
15320 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15322 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

15381 (syms_of_keymap): Defsubr make-composed-keymap.
15382 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

15419 * eval.c (struct backtrace): Simplify and port the data structure.
15420 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
15421 signed bit field, as this assumption is not portable and it makes
15422 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
15423 "char debug_on_exit : 1" as this is not portable either; instead,
15424 use the portable "unsigned int debug_on_exit : 1". Remove unused
15425 member evalargs. Remove obsolete comments about cc bombing out.
15427 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

15629 Now ptrdiff_t, not int.
15630 (read1): Don't assume doc string length fits in int. Check for
15631 out-of-range doc string lengths.
15632 (read_list): Don't assume file position fits in int.
15633 (read_escape): Check for hex character overflow.
15635 2011-06-22 Leo Liu <sdl.web@gmail.com>
15637 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
15638 Move to minibuffer.el.
15640 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
15642 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
15643 The following patches are for when GLYPH_DEBUG && !XASSERT.
15644 * dispextern.h (trace_redisplay_p, dump_glyph_string):
15645 * dispnew.c (flush_stdout):
15646 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
15647 Mark as externally visible.
15648 * dispnew.c (check_window_matrix_pointers): Now static.
15649 * dispnew.c (window_to_frame_vpos):
15650 * xfns.c (unwind_create_frame):
15651 * xterm.c (x_check_font): Remove unused local.
15652 * scroll.c (CHECK_BOUNDS):
15653 * xfaces.c (cache_fache): Rename local to avoid shadowing.
15654 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
15655 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
15656 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
15657 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
15659 (debug_method_add): Use va_list and vsprintf rather than relying
15660 on undefined behavior with wrong number of arguments.
15661 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
15662 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
15663 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
15664 since we're not interested in debugging glyphs with old libraries.
15665 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
15666 GCC 4.6.0's static checking.
15668 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
15670 Integer overflow and signedness fixes (Bug#8873).

15679 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
15680 (x_create_bitmap_from_xpm_data):
15681 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
15682 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
15684 * xfaces.c (load_pixmap):
15685 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
15686 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
15687 (.bitmaps_last, struct x_output.icon_bitmap):
15688 Use ptrdiff_t, not int, for bitmap indexes.
15689 (x_allocate_bitmap_record): Check for size overflow.
15690 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
15692 Use ptrdiff_t, not int, for overlay counts.
15693 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
15694 * editfns.c (overlays_around, get_pos_property):
15695 * textprop.c (get_char_property_and_overlay):
15696 * xdisp.c (next_overlay_change, note_mouse_highlight):
15697 * xfaces.c (face_at_buffer_position):
15698 * buffer.c (OVERLAY_COUNT_MAX): New macro.
15699 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
15700 (Fnext_overlay_change, Fprevious_overlay_change)
15701 (mouse_face_overlay_overlaps, Foverlays_in):
15702 Use ptrdiff_t, not int, for sizes.
15703 (overlays_at, overlays_in): Check for size-calculation overflow.
15705 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
15707 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
15708 (x_session_initialize): Do not assume string length fits in int.
15710 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
15711 This is unlikely, but can occur if DPI is outlandish.
15713 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
15714 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
15716 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
15717 * xrdb.c (magic_file_p, search_magic_path):
15718 Omit last arg SUFFIX; it was always 0. All callers changed.
15719 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
15721 * xfont.c (xfont_match): Avoid need for strlen.
15723 * xfns.c: Don't assume strlen fits in int.
15724 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
15726 * xdisp.c (message_log_check_duplicate): Return intmax_t,
15727 not unsigned long, as we prefer signed integers. All callers changed.
15728 Detect integer overflow in repeat count.
15729 (message_dolog): Don't assume print length fits in 39 bytes.
15730 (display_mode_element): Don't assume strlen fits in int.
15732 * termcap.c: Don't assume sizes fit in int and never overflow.
15733 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
15734 (gobble_line): Check for size-calculation overflow.
15736 * minibuf.c (Fread_buffer):
15737 * lread.c (intern, intern_c_string):
15738 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
15739 Don't assume string length fits in int.
15741 * keyboard.c (parse_tool_bar_item):
15742 * gtkutil.c (style_changed_cb): Avoid need for strlen.
15744 * font.c: Don't assume string length fits in int.
15745 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
15746 Use ptrdiff_t, not int.
15747 (font_intern_prop): Don't assume string length fits in int.
15748 Don't assume integer property fits in fixnum.
15749 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
15751 * filelock.c: Fix some buffer overrun and integer overflow issues.
15752 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
15753 Reformulate so as not to need the command string.
15754 Invoke gzip -cd rather than gunzip, as it's more portable.
15755 (lock_info_type, lock_file_1, lock_file):
15756 Don't assume pid_t and time_t fit in unsigned long.
15757 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
15758 (current_lock_owner): Prefer signed type for sizes.
15759 Use memcpy, not strncpy, where memcpy is what is really wanted.
15760 Don't assume (via atoi) that time_t and pid_t fit in int.
15761 Check for time_t and/or pid_t out of range, e.g., via a network share.
15762 Don't alloca where an auto var works fine.
15764 * fileio.c: Fix some integer overflow issues.
15765 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
15766 Don't assume string length fits in int.
15767 (directory_file_name): Don't assume string length fits in long.
15768 (make_temp_name): Don't assume pid fits in int, or that its print
15769 length is less than 20.
15771 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
15773 * coding.c (make_subsidiaries): Don't assume string length fits in int.
15775 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
15777 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
15778 We prefer signed integers, even for size calculations.
15780 * emacs.c: Don't assume string length fits in 'int'.
15781 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
15782 (main): Don't invoke strlen when not needed.
15784 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
15785 (XD_DEBUG_MESSAGE): Don't waste a byte.
15787 * callproc.c (getenv_internal_1, getenv_internal)
15788 (Fgetenv_internal):
15789 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
15791 * lread.c (invalid_syntax): Omit length argument.
15792 All uses changed. This doesn't fix a bug, but it simplifies the
15793 code away from its former Hollerith-constant appearance, and it's
15794 one less 'int' to worry about when looking at integer-overflow issues.
15795 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
15797 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
15798 This didn't break anything, but it didn't help either.
15799 It's confusing to put a bogus integer in a place where the actual
15800 value does not matter.
15801 (LIST_END_P): Remove unused macro and its bogus comment.
15802 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
15804 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
15805 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
15807 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
15808 We prefer signed types, and the value cannot exceed the EMACS_INT
15809 range anyway (because otherwise the length would not be representable).
15810 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
15811 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
15812 This avoids a GCC warning when WIDE_EMACS_INT.
15814 * indent.c (sane_tab_width): New function.
15815 (current_column, scan_for_column, Findent_to, position_indentation)
15816 (compute_motion): Use it. This is just for clarity.
15817 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
15819 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
15821 * lisp.h (lint_assume): New macro.
15822 * composite.c (composition_gstring_put_cache):
15823 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
15825 * editfns.c, insdel.c:
15826 Omit unnecessary forward decls, to simplify future changes.
15828 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
15830 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
15832 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
15833 Use much-faster test for byte-length change.
15834 Don't assume string byte-length fits in 'int'.
15835 Check that character arg fits in 'int'.
15836 (mapcar1): Declare byte as byte, for clarity.
15838 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
15840 * fns.c (concat): Catch string overflow earlier.
15841 Do not rely on integer wraparound.
15843 * dispextern.h (struct it.overlay_strings_charpos)
15844 (struct it.selective): Now EMACS_INT, not int.
15845 * xdisp.c (forward_to_next_line_start)
15846 (back_to_previous_visible_line_start)
15847 (reseat_at_next_visible_line_start, next_element_from_buffer):
15848 Don't arbitrarily truncate the value of 'selective' to int.
15850 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
15852 * composite.c: Don't truncate sizes to 'int'.
15853 (composition_gstring_p, composition_reseat_it)
15854 (composition_adjust_point): Use EMACS_INT, not int.
15855 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
15856 not EMACS_UINT, for indexes.
15858 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
15860 * buffer.c: Include <verify.h>.
15861 (struct sortvec.priority, struct sortstr.priority):
15862 Now EMACS_INT, not int.
15863 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
15864 (struct sortstr.size, record_overlay_string)
15865 (struct sortstrlist.size, struct sortlist.used):
15866 Don't truncate size to int.
15867 (record_overlay_string): Check for size-calculation overflow.
15868 (init_buffer_once): Check at compile-time, not run-time.
15870 2011-06-22 Jim Meyering <meyering@redhat.com>
15872 Don't leak an XBM-image-sized buffer
15873 * image.c (xbm_load): Free the image buffer after using it.
15875 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
15878 * composite.c (find_automatic_composition): Omit needless 'return 0;'
15879 that Sun C diagnosed.
15880 * fns.c (secure_hash): Fix pointer signedness issue.
15881 * intervals.c (static_offset_intervals): New function.
15882 (offset_intervals): Use it.
15884 2011-06-21 Leo Liu <sdl.web@gmail.com>
15887 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
15890 * fns.c (secure_hash): Rename from crypto_hash_function and change
15891 the first arg to accept symbols.
15892 (Fsecure_hash): New primitive.
15893 (syms_of_fns): New symbols.
15895 2011-06-20 Deniz Dogan <deniz@dogan.se>
15897 * process.c (Fset_process_buffer): Clarify return value in
15900 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
15902 * dispnew.c (add_window_display_history): Use BVAR.
15904 * xdisp.c (debug_method_add): Use BVAR.
15905 (check_window_end, dump_glyph_matrix, dump_glyph)
15906 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
15908 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
15911 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
15912 check till after the cache is created in init_frame_faces.
15914 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
15916 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
15918 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
15920 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
15921 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
15922 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
15924 Improve buffer-overflow checking (Bug#8873).
15925 * fileio.c (Finsert_file_contents):
15926 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
15927 Remove the old (too-loose) buffer overflow checks.
15928 They weren't needed, since make_gap checks for buffer overflow.
15929 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
15930 The old code merely checked for Emacs fixnum overflow, and relied
15931 on undefined (wraparound) behavior. The new code avoids undefined
15932 behavior, and also checks for ptrdiff_t and/or size_t overflow.
15934 * editfns.c (Finsert_char): Don't dump core with very negative counts.
15935 Tune. Don't use wider integers than needed. Don't use alloca.
15936 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
15938 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
15940 * insdel.c, lisp.h (buffer_overflow): New function.
15941 (insert_from_buffer_1, replace_range, replace_range_2):
15942 * insdel.c (make_gap_larger):
15943 * editfns.c (Finsert_char):
15944 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
15946 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
15948 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
15950 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
15952 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
15953 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
15955 * fileio.c: Don't assume EMACS_INT fits in off_t.
15956 (emacs_lseek): New static function.
15957 (Finsert_file_contents, Fwrite_region): Use it.
15958 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
15960 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
15962 * fns.c: Don't overflow int when computing a list length.
15963 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
15964 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
15965 truncation on 64-bit hosts. Check for QUIT every
15966 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
15967 faster and is responsive enough.
15968 (Flength): Report an error instead of overflowing an integer.
15969 (Fsafe_length): Return a float if the value is not representable
15970 as a fixnum. This shouldn't happen except in contrived situations.
15971 (Fnthcdr, Fsort): Don't assume list length fits in int.
15972 (Fcopy_sequence): Don't assume vector length fits in int.
15974 * alloc.c: Check that resized vectors' lengths fit in fixnums.
15975 (header_size, word_size): New constants.
15976 (allocate_vectorlike): Don't check size overflow here.
15977 (allocate_vector): Check it here instead, since this is the only
15978 caller of allocate_vectorlike that could cause overflow.
15979 Check that the new vector's length is representable as a fixnum.
15981 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
15982 The previous code was bogus. For example, next_almost_prime (32)
15983 returned 39, which is undesirable as it is a multiple of 3; and
15984 next_almost_prime (24) returned 25, which is a multiple of 5 so
15985 why was the code bothering to check for multiples of 7?
15987 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
15989 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
15991 Variadic C functions now count arguments with ptrdiff_t.
15992 This partly undoes my 2011-03-30 change, which replaced int with size_t.
15993 Back then I didn't know that the Emacs coding style prefers signed int.
15994 Also, in the meantime I found a few more instances where arguments
15995 were being counted with int, which may truncate counts on 64-bit
15996 machines, or EMACS_INT, which may be unnecessarily wide.
15997 * lisp.h (struct Lisp_Subr.function.aMANY)
15998 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
15999 Arg counts are now ptrdiff_t, not size_t.
16000 All variadic functions and their callers changed accordingly.
16001 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
16002 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
16003 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
16004 * callint.c (Fcall_interactively): Check arg count for overflow,
16005 to avoid potential buffer overrun. Use signed char, not 'int',
16006 for 'varies' array, so that we needn't bother to check its size
16007 calculation for overflow.
16008 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
16009 * eval.c (apply_lambda):
16010 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
16011 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
16012 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
16014 * callint.c (Fcall_interactively): Don't use index var as event count.
16016 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
16017 * mem-limits.h (SIZE): Remove; no longer used.
16019 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
16021 Remove unnecessary casts.
16022 * xterm.c (x_term_init):
16023 * xfns.c (x_set_border_pixel):
16024 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
16025 These aren't needed now that we assume ANSI C.
16027 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
16028 It's more likely to cause problems (due to unsigned overflow)
16031 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
16033 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
16035 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
16037 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
16039 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
16041 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
16043 GLYPH_CODE_FACE returns EMACS_INT, not int.
16044 * dispextern.h (merge_faces):
16045 * xfaces.c (merge_faces):
16046 * xdisp.c (get_next_display_element, next_element_from_display_vector):
16047 Don't assume EMACS_INT fits in int.
16049 * character.h (CHAR_VALID_P): Remove unused parameter.
16050 * fontset.c, lisp.h, xdisp.c: All uses changed.
16052 * editfns.c (Ftranslate_region_internal): Omit redundant test.
16054 * fns.c (concat): Minor tuning based on overflow analysis.
16055 This doesn't fix any bugs. Use int to hold character, instead
16056 of constantly refetching from Emacs object. Use XFASTINT, not
16057 XINT, for value known to be a character. Don't bother comparing
16058 a single byte to 0400, as it's always less.
16060 * floatfns.c (Fexpt):
16061 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
16063 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
16066 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
16068 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
16069 Without this fix, on a 64-bit host (aset S 0 4294967386) would
16070 incorrectly succeed when S was a string, because 4294967386 was
16071 truncated before it was used.
16073 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
16074 Otherwise, an out-of-range integer could cause undefined behavior
16077 * composite.c: Use int, not EMACS_INT, for characters.
16078 (fill_gstring_body, composition_compute_stop_pos): Use int, not
16079 EMACS_INT, for values that are known to be in character range.
16080 This doesn't fix any bugs but is the usual style inside Emacs and
16081 may generate better code on 32-bit machines.
16083 Make sure a 64-bit char is never passed to ENCODE_CHAR.
16084 This is for reasons similar to the recent CHAR_STRING fix.
16085 * charset.c (Fencode_char): Check that character arg is actually
16086 a character. Pass an int to ENCODE_CHAR.
16087 * charset.h (ENCODE_CHAR): Verify that the character argument is no
16088 wider than 'int', as a compile-time check to prevent future regressions
16091 * character.c (char_string): Remove unnecessary casts.
16093 Make sure a 64-bit char is never passed to CHAR_STRING.
16094 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
16095 by silently ignoring the top 32 bits, allowing some values
16096 that were far too large to be valid characters.
16097 * character.h: Include <verify.h>.
16098 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
16099 arguments are no wider than unsigned, as a compile-time check
16100 to prevent future regressions in this area.
16102 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
16103 (Fsubst_char_in_region):
16105 * xdisp.c (decode_mode_spec_coding):
16106 Adjust to CHAR_STRING's new requirement.
16107 * editfns.c (Finsert_char, Fsubst_char_in_region):
16108 * fns.c (concat): Check that character args are actually
16109 characters. Without this test, these functions did the wrong
16110 thing with wildly out-of-range values on 64-bit hosts.
16112 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
16113 These casts should not be needed on 32-bit hosts, either.
16114 * keyboard.c (read_char):
16115 * lread.c (Fload): Remove casts to unsigned.
16117 * lisp.h (UNSIGNED_CMP): New macro.
16118 This fixes comparison bugs on 64-bit hosts.
16119 (ASCII_CHAR_P): Use it.
16120 * casefiddle.c (casify_object):
16121 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
16122 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
16123 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
16124 * dispextern.h (FACE_FROM_ID):
16125 * keyboard.c (read_char): Use UNSIGNED_CMP.
16127 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
16128 not to EMACS_INT, to avoid GCC warning.
16130 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
16132 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
16133 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
16134 isn't needed on 32-bit machines.
16136 * buffer.c (Fgenerate_new_buffer_name):
16137 Use EMACS_INT for count, not int.
16138 (advance_to_char_boundary): Return EMACS_INT, not int.
16140 * data.c (Qcompiled_function): Now static.
16142 * window.c (window_body_lines): Now static.
16144 * image.c (gif_load): Rename local to avoid shadowing.
16146 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
16147 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
16148 * alloc.c (make_save_value): Integer argument is now of type
16149 ptrdiff_t, not int.
16150 (mark_object): Use ptrdiff_t, not int.
16151 * lisp.h (pD): New macro.
16152 * print.c (print_object): Use it.
16154 * alloc.c: Use EMACS_INT, not int, to count objects.
16155 (total_conses, total_markers, total_symbols, total_vector_size)
16156 (total_free_conses, total_free_markers, total_free_symbols)
16157 (total_free_floats, total_floats, total_free_intervals)
16158 (total_intervals, total_strings, total_free_strings):
16159 Now EMACS_INT, not int. All uses changed.
16160 (Fgarbage_collect): Compute overall total using a double, so that
16161 integer overflow is less likely to be a problem. Check for overflow
16162 when converting back to an integer.
16163 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
16164 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
16165 These were 'int' variables that could overflow on 64-bit hosts;
16166 they were never used, so remove them instead of repairing them.
16167 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
16168 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
16169 Previously, this ceilinged at INT_MAX, but that doesn't work on
16171 (allocate_pseudovector): Don't use EMACS_INT when int would do.
16173 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
16174 (allocate_vectorlike): Check for ptrdiff_t overflow.
16175 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
16176 when a (possibly-narrower) signed value would do just as well.
16177 We prefer using signed arithmetic, to avoid comparison confusion.
16179 * alloc.c: Catch some string size overflows that we were missing.
16180 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
16181 for convenience in STRING_BYTES_MAX.
16182 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
16183 The definition here is exact; the one in lisp.h was approximate.
16184 (allocate_string_data): Check for string overflow. This catches
16185 some instances we weren't catching before. Also, it catches
16186 size_t overflow on (unusual) hosts where SIZE_MAX <= min
16187 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
16188 and ptrdiff_t and EMACS_INT are both 64 bits.
16190 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
16191 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
16192 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
16194 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
16196 * alloc.c (Fmake_string): Check for out-of-range init.
16198 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
16200 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
16202 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
16204 * xfns.c (x_set_scroll_bar_default_width): Remove argument to

16207 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
16208 (int_gtk_range_get_value): Move to the scroll bar part of the file.
16209 (style_changed_cb): Call update_theme_scrollbar_width and call

16211 all frames (Bug#8505).
16212 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
16213 Call gtk_window_set_resizable if HAVE_GTK3.

16215 and height if HAVE_GTK3 (Bug#8505).
16216 (scroll_bar_width_for_theme): New variable.
16217 (update_theme_scrollbar_width): New function.
16218 (xg_get_default_scrollbar_width): Move code to
16219 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.

16222 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
16224 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
16226 2011-06-12 Martin Rudalics <rudalics@gmx.at>
16228 * frame.c (make_frame): Call other_buffer_safely instead of
16231 * window.c (temp_output_buffer_show): Call display_buffer with
16232 second argument Vtemp_buffer_show_specifiers and reset latter
16233 immediately after the call.
16234 (Vtemp_buffer_show_specifiers): New variable.
16235 (auto_window_vscroll_p, next_screen_context_lines)
16236 (Vscroll_preserve_screen_position): Remove leading asterisks from

16787 (display_prop_intangible_p): Reimplement to call
16788 handle_display_spec instead of single_display_spec_intangible_p.

16800 value of a `display' property is a "replacing spec".
16801 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
16802 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

16832 * gnutls.c: Use Emacs's memory allocators.
16833 Without this change, the gnutls library would invoke malloc etc.
16834 directly, which causes problems on non-SYNC_INPUT hosts, and which
16835 runs afoul of improving memory_full behavior. (Bug#8761)
16836 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
16837 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
16838 xfree instead of the default malloc, realloc, free.
16839 (Fgnutls_boot): No need to check for memory allocation failure,
16840 since xmalloc does that for us.

16869 need to be updated by these changes.
16870 * fns.c (make_hash_table, maybe_resize_hash_table):
16871 Check for integer overflow with large hash tables.
16872 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
16873 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
16874 (SXHASH_REDUCE): New macro.
16875 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
16876 Use it instead of discarding useful hash info with large hash values.
16877 (sxhash_float): New function.
16878 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
16879 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
16880 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
16881 Rewrite to use FIXNUM_BITS, as this simplifies things.
16882 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
16883 Adjust signatures to match updated version of code.
16884 (consing_since_gc): Now EMACS_INT, since a single hash table can
16885 use more than INT_MAX bytes.

16928 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
16929 * gmalloc.c (register_heapinfo): Use inline unconditionally.
16930 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
16932 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
16934 Make it possible to run ./temacs.
16936 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
16937 syms_of_callproc does the same thing. Remove test for
16938 "initialized", do it in the caller.
16939 * emacs.c (main): Avoid calling set_initial_environment when dumping.
16941 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
16943 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
16944 (read_minibuf): Use get_minibuffer.
16945 (syms_of_minibuf): Use DEFSYM.
16946 (Qmetadata): New var.
16947 * data.c (Qbuffer): Don't make it static.
16948 (syms_of_data): Use DEFSYM.
16950 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
16952 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
16953 (CCL_CODE_MIN): New macro.
16955 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
16957 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
16959 * eval.c (Qdebug): Now static.
16960 * lisp.h (Qdebug): Remove decl. This reverts a part of the
16961 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
16962 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
16964 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
16966 * image.c: Various fixes to ImageMagick code comments.
16967 (Fimagemagick_types): Doc fix.
16969 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
16971 Minor fixes prompted by GCC 4.6.0 warnings.
16973 * xselect.c (converted_selections, conversion_fail_tag): Now static.
16975 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
16976 (x_clipboard_manager_save_all): Move extern decl to ...
16977 * xterm.h: ... here, so that it can be checked for consistency.
16979 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
16981 * xselect.c (x_clipboard_manager_save_frame)
16982 (x_clipboard_manager_save_all): New functions.
16983 (Fx_clipboard_manager_save): Lisp function deleted.
16985 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
16986 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
16988 * xterm.h: Update prototype.
16990 2011-05-28 William Xu <william.xwl@gmail.com>
16992 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
16993 exiting (Bug#8239).
16995 2011-05-28 Jim Meyering <meyering@redhat.com>
16997 Avoid a sign-extension bug in crypto_hash_function.
16998 * fns.c (to_uchar): Define.
16999 (crypto_hash_function): Use it to convert some newly-signed
17000 variables to unsigned, to avoid sign-extension bugs. For example,
17001 without this change, (md5 "truc") would evaluate to
17002 45723a2aff78ff4fff7fff1114760e62 rather than the expected
17003 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
17004 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
17006 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17008 Integer overflow fixes.
17010 * dbusbind.c: Serial number integer overflow fixes.
17011 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
17012 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
17013 to hold a serial number that is too large for a fixnum.
17014 (Fdbus_method_return_internal, Fdbus_method_error_internal):
17015 Check for serial numbers out of range. Decode any serial number
17016 that was so large that it became a float. (Bug#8722)
17018 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
17019 (Fdbus_call_method, Fdbus_call_method_asynchronously):
17020 Use XFASTINT rather than XUINT when numbers are nonnegative.
17021 (xd_append_arg, Fdbus_method_return_internal):
17022 (Fdbus_method_error_internal): Likewise. Also, for unsigned
17023 arguments, check that Lisp number is nonnegative, rather than
17024 silently wrapping negative numbers around. (Bug#8722)
17025 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
17028 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
17030 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
17032 ccl: Add integer overflow checks.
17033 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
17034 (IN_INT_RANGE): New macros.
17035 (ccl_driver): Use them to check for integer overflow when
17036 decoding a CCL program. Many of the new checks are whether XINT (x)
17037 fits in int; it doesn't always, on 64-bit hosts. The new version
17038 doesn't catch all possible integer overflows, but it's an
17039 improvement. (Bug#8719)
17041 * alloc.c (make_event_array): Use XINT, not XUINT.
17042 There's no need for unsigned here.
17044 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
17045 This follows up to the 2011-05-06 change that substituted uintptr_t
17046 for EMACS_INT. This case wasn't caught back then.
17048 Rework Fformat to avoid integer overflow issues.
17049 * editfns.c: Include <float.h> unconditionally, as it's everywhere
17050 now (part of C89). Include <verify.h>.
17051 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
17052 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
17053 (Fformat): Avoid the prepass trying to compute sizes; it was only
17054 approximate and thus did not catch overflow reliably. Instead, walk
17055 through the format just once, formatting and computing sizes as we go,
17056 checking for integer overflow at every step, and allocating a larger
17057 buffer as needed. Keep track separately whether the format is
17058 multibyte. Keep only the most-recently calculated precision, rather
17059 than them all. Record whether each argument has been converted to
17060 string. Use EMACS_INT, not int, for byte and char and arg counts.
17061 Support field widths and precisions larger than INT_MAX. Avoid
17062 sprintf's undefined behavior with conversion specifications such as %#d
17063 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
17064 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
17065 formatting out-of-range floating point numbers with int
17066 formats. (Bug#8668)
17068 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
17070 * data.c: Avoid integer truncation in expressions involving floats.
17071 * data.c: Include <intprops.h>.
17072 (arith_driver): When there's an integer overflow in an expression
17073 involving floating point, convert the integers to floating point
17074 so that the resulting value does not suffer from catastrophic
17075 integer truncation. For example, on a 64-bit host (* 4
17076 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
17077 Do not rely on undefined behavior after integer overflow.
17079 merge count_size_as_multibyte, parse_str_to_multibyte
17080 * character.c, character.h (count_size_as_multibyte):
17081 Rename from parse_str_to_multibyte; all uses changed.
17082 Check for integer overflow.
17083 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
17084 since it's now a duplicate of the other. This is more of
17085 a character than a buffer op, so better that it's in character.c.
17086 * fns.c, print.c: Adjust to above changes.
17088 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
17090 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
17092 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17094 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17095 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
17096 (x_clipboard_manager_save): Now static.
17097 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
17099 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17100 (crypto_hash_function): Now static.
17101 Fix pointer signedness problems. Avoid unnecessary initializations.
17103 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
17105 * termhooks.h (Vselection_alist): Make it terminal-local.
17107 * terminal.c (create_terminal): Initialize it.
17109 * xselect.c: Support for clipboard managers.
17110 (Vselection_alist): Move to termhooks.h as terminal-local var.
17111 (LOCAL_SELECTION): New macro.
17112 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
17113 (symbol_to_x_atom): Remove gratuitous arg.
17114 (x_handle_selection_request, lisp_data_to_selection_data)
17115 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
17116 (x_own_selection, x_get_local_selection, x_convert_selection):
17117 New arg, specifying work frame. Use terminal-local Vselection_alist.
17118 (some_frame_on_display): Delete unused function.
17119 (Fx_own_selection_internal, Fx_get_selection_internal)
17120 (Fx_disown_selection_internal, Fx_selection_owner_p)
17121 (Fx_selection_exists_p): New optional frame arg.
17122 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
17123 (x_handle_selection_clear): Don't treat other terminals with the
17124 same keyboard specially. Use the terminal-local Vselection_alist.
17125 (x_clear_frame_selections): Use Frun_hook_with_args.
17127 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
17129 * xterm.h: Add support for those atoms.
17131 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
17133 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
17134 (converted_selections, conversion_fail_tag): New global variables.
17135 (x_selection_request_lisp_error): Free the above.
17136 (x_get_local_selection): Remove unnecessary code.
17137 (x_reply_selection_request): Args changed; handle arbitrary array
17138 of converted selections stored in converted_selections.
17139 Separate the XChangeProperty and SelectionNotify steps.
17140 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
17141 (x_convert_selection): New function.
17142 (x_handle_selection_event): Simplify.
17143 (x_get_foreign_selection): Don't ignore incoming requests while
17144 waiting for an answer; this will fail when we implement
17145 SAVE_TARGETS, and seems unnecessary anyway.
17146 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
17147 (Vx_sent_selection_functions): Doc fix.
17149 2011-05-26 Leo Liu <sdl.web@gmail.com>
17151 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
17153 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17155 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
17157 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
17158 for fringe update if it has periodic bitmap.
17159 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
17160 and fringe_bitmap_periodic_p.
17162 * fringe.c (get_fringe_bitmap_data): New function.
17163 (draw_fringe_bitmap_1, update_window_fringes): Use it.
17164 (update_window_fringes): Record periodicity of fringe bitmap in glyph
17165 row. Mark glyph row for fringe update if periodicity changed.
17167 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
17168 for fringe update unless it has periodic bitmap.
17170 2011-05-25 Kenichi Handa <handa@m17n.org>
17172 * xdisp.c (get_next_display_element): Set correct it->face_id for
17173 a static composition.
17175 2011-05-24 Leo Liu <sdl.web@gmail.com>
17178 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
17180 * fns.c (crypto_hash_function, Fsha1): New function.
17181 (Fmd5): Use crypto_hash_function.
17182 (syms_of_fns): Add Ssha1.
17184 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
17186 * gnutls.c: Remove unused macros.
17187 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
17188 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
17189 Remove macros that are defined and never used.
17190 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
17192 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17194 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
17195 (Fx_get_selection_internal): Minor cleanup.
17196 (Fx_own_selection_internal): Rename arguments for consistency with
17199 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
17201 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
17203 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17205 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
17207 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17209 * dispnew.c (scrolling_window): Don't exclude the case that the
17210 last enabled row in the desired matrix touches the bottom boundary.
17212 2011-05-21 Glenn Morris <rgm@gnu.org>
17214 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
17215 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
17216 and add some more files.
17218 2011-05-20 Eli Zaretskii <eliz@gnu.org>
17220 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
17221 report_file_error introduced by the change from 2011-05-07.
17223 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
17225 * systime.h (Time): Define only if emacs is defined.
17226 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
17227 where the include path doesn't have X11/X.h by default. See
17228 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
17230 2011-05-20 Kenichi Handa <handa@m17n.org>
17232 * composite.c (find_automatic_composition): Fix previous change.
17234 2011-05-20 Glenn Morris <rgm@gnu.org>
17236 * lisp.mk: New file, split from Makefile.in.
17237 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
17238 (shortlisp): Remove.
17239 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
17241 2011-05-19 Glenn Morris <rgm@gnu.org>
17243 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
17244 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
17245 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
17246 (lisp): Set the order to that of loadup.el.
17247 (shortlisp): Make it a copy of $lisp.
17248 (SOME_MACHINE_LISP): Remove.
17249 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
17250 Use just $shortlisp, not $SOME_MACHINE_LISP too.
17252 2011-05-18 Kenichi Handa <handa@m17n.org>
17254 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
17255 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
17256 (find_automatic_composition): Mostly rewrite for efficiency.
17258 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
17260 * makefile.w32-in: Update dependencies.
17262 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
17264 * menu.c: Include limits.h (fixes the MS-Windows build broken by
17265 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
17267 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
17269 Fix some integer overflow issues, such as string length overflow.
17271 * insdel.c (count_size_as_multibyte): Check for string overflow.
17273 * character.c (lisp_string_width): Check for string overflow.
17274 Use EMACS_INT, not int, for string indexes and lengths; in
17275 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
17276 the resulting string length overflows an EMACS_INT; instead,
17277 report a string overflow if no precision given. When checking for
17278 precision exhaustion, use a check that cannot possibly have
17279 integer overflow. (Bug#8675)
17280 * character.h (lisp_string_width): Adjust to new signature.
17282 * alloc.c (string_overflow): New function.
17283 (Fmake_string): Use it. This doesn't change behavior, but saves
17284 a few bytes and will simplify future changes.
17285 * character.c (string_escape_byte8): Likewise.
17286 * lisp.h (string_overflow): New decl.
17288 Fixups, following up to the user-interface timestamp change.
17289 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
17290 for UI timestamps, instead of unsigned long.
17291 * msdos.c (mouse_get_pos): Likewise.
17292 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
17293 * w32gui.h (Time): Define by including "systime.h" rather than by
17294 declaring it ourselves. (Bug#8664)
17296 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
17297 * image.c (clear_image_cache): Likewise.
17299 * term.c (term_mouse_position): Don't assume time_t wraparound.
17301 Be more systematic about user-interface timestamps.
17302 Before, the code sometimes used 'Time', sometimes 'unsigned long',
17303 and sometimes 'EMACS_UINT', to represent these timestamps.
17304 This change causes it to use 'Time' uniformly, as that's what X uses.
17305 This makes the code easier to follow, and makes it easier to catch
17306 integer overflow bugs such as Bug#8664.
17307 * frame.c (Fmouse_position, Fmouse_pixel_position):
17308 Use Time, not unsigned long, for user-interface timestamps.
17309 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
17310 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
17311 * keyboard.h (last_event_timestamp): Likewise.
17312 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
17313 * menu.h (xmenu_show): Likewise.
17314 * term.c (term_mouse_position): Likewise.
17315 * termhooks.h (struct input_event.timestamp): Likewise.
17316 (struct terminal.mouse_position_hook): Likewise.
17317 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
17318 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
17319 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
17320 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
17321 what it was before.
17322 * menu.h, termhooks.h: Include "systime.h", for Time.
17324 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
17325 Don't assume that the difference between two unsigned long values
17326 can fit into an integer. At this point, we know button_down_time
17327 <= event->timestamp, so the difference must be nonnegative, so
17328 there's no need to cast the result if double-click-time is
17329 nonnegative, as it should be; check that it's nonnegative, just in
17330 case. This bug is triggered when events are more than 2**31 ms
17331 apart (about 25 days). (Bug#8664)
17333 * xselect.c (last_event_timestamp): Remove duplicate decl.
17334 (x_own_selection): Remove needless cast to unsigned long.
17336 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
17337 that always fit in int. Use a sentinel instead of a counter, to
17338 avoid a temp and to allay GCC's concerns about possible int overflow.
17339 * frame.h (struct frame): Use int for menu_bar_items_used
17340 instead of EMACS_INT, since it always fits in int.
17342 * menu.c (grow_menu_items): Check for int overflow.
17344 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
17346 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
17347 Before, the code was not consistent. These values cannot exceed
17348 2**31 - 1 so there's no need to make them unsigned.
17349 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
17350 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
17351 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
17353 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
17355 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
17356 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
17357 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
17358 presumably because the widths might not match.
17360 * window.c (size_window): Avoid needless test at loop start.
17362 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
17364 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
17366 2011-05-12 Drew Adams <drew.adams@oracle.com>
17368 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
17370 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17372 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
17373 `width' to `bar_area_x' and `bar_area_width', respectively.
17374 (x_scroll_run): Take account of fringe background extension.
17376 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
17377 Rename local vars `left' and `width' to `bar_area_x' and
17378 `bar_area_width', respectively.
17379 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
17380 background extension.
17382 2011-05-10 Jim Meyering <meyering@redhat.com>
17384 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
17386 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
17388 * image.c (Finit_image_library): Return t for built-in image types,
17389 like pbm and xbm. (Bug#8640)
17391 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
17393 * w32menu.c (set_frame_menubar): Fix submenu allocation.
17395 2011-05-07 Eli Zaretskii <eliz@gnu.org>
17397 * w32console.c (Fset_screen_color): Doc fix.
17398 (Fget_screen_color): New function.
17399 (syms_of_ntterm): Defsubr it.
17401 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
17402 unlink the temporary file if Fcall_process didn't create it in the
17404 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
17405 child process will be redirected to a file specified with `:file'.
17406 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
17407 cue to call_process_cleanup not to close that handle.
17409 2011-05-07 Ben Key <bkey76@gmail.com>
17411 * makefile.w32-in: The bootstrap-temacs rule now makes use of
17412 one of two shell specific rules, either bootstrap-temacs-CMD or
17413 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
17414 to the previous implementation of the bootstrap-temacs rule.
17415 The bootstrap-temacs-CMD rule is similar to the previous
17416 implementation of the bootstrap-temacs rule except that it
17417 makes use of the ESC_CFLAGS variable instead of the CFLAGS
17420 These changes, along with some changes to nt/configure.bat,
17421 nt/gmake.defs, and nt/nmake.defs, are required to extend my
17422 earlier fix to add support for --cflags and --ldflags options
17423 that include quotes so that it works whether make uses cmd or
17426 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
17428 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
17429 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
17431 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
17432 a string. Handle both cases.
17433 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
17434 (Fdbus_register_method): Use Qinvalid_function.
17436 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
17438 * makefile.w32-in: Update dependencies.
17439 (LISP_H): Add inttypes.h and stdin.h.
17440 (PROCESS_H): Add unistd.h.
17442 2011-05-06 Eli Zaretskii <eliz@gnu.org>
17444 * lread.c: Include limits.h (fixes the MS-Windows build broken by
17445 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
17447 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
17449 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
17451 * term.c (vfatal): Remove stray call to va_end.
17452 It's not needed and the C Standard doesn't allow it here anyway.
17454 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
17455 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
17457 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
17460 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
17462 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
17464 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
17466 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
17468 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
17470 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
17471 * charset.c (Fdefine_charset_internal): Don't initialize
17472 charset.code_space[15]. The value was garbage, on hosts with
17473 32-bit int (Bug#8600).
17475 * lread.c (read_integer): Be more consistent with string-to-number.
17476 Use string_to_number to do the actual conversion; this avoids
17477 rounding errors and fixes some other screwups. Without this fix,
17478 for example, #x1fffffffffffffff was misread as -2305843009213693952.
17479 (digit_to_number): Move earlier, for benefit of read_integer.
17480 Return -1 if the digit is out of range for the base, -2 if it is
17481 not a digit in any supported base. (Bug#8602)
17483 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
17485 * dispnew.c (scrolling_window): Return 1 if we scrolled,
17486 to match comment at start of function. This also removes a
17487 GCC warning about overflow in a 32+64-bit port.
17489 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
17491 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
17492 Reported by Stefan Monnier in
17493 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
17494 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
17495 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
17497 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
17498 (EMACS_UINTPTR): Likewise, with uintptr_t.
17500 * lisp.h: Prefer 64-bit EMACS_INT if available.
17501 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
17502 on 32-bit hosts that have 64-bit int, so that they can access
17504 However, temporarily disable this change unless the temporary
17505 symbol WIDE_EMACS_INT is defined.
17507 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
17509 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
17510 This removes an assumption that EMACS_INT and long are the same
17511 width as pointers. The assumption is true for Emacs porting targets
17512 now, but we want to make other targets possible.
17513 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
17514 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
17515 In the rest of the code, change types of integers that hold casted
17516 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
17517 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
17518 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
17519 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
17520 No need to cast type when ORing.
17521 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
17522 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
17523 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
17524 assume EMACS_INT is the same width as char *.
17525 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
17526 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
17527 Remove no-longer-needed casts.
17528 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
17529 (xg_tool_bar_help_callback, xg_make_tool_item):
17530 Use EMACS_INTPTR to hold an integer
17531 that will be cast to void *; this can avoid a GCC warning
17532 if EMACS_INT is not the same width as void *.
17533 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
17534 * xdisp.c (display_echo_area_1, resize_mini_window_1):
17535 (current_message_1, set_message_1):
17536 Use a local to convert to proper width without a cast.
17537 * xmenu.c (dialog_selection_callback): Likewise.
17539 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
17540 Also, don't assume VALBITS / RAND_BITS is less than 5,
17541 and don't rely on undefined behavior when shifting a 1 left into
17543 * lisp.h (get_random): Change signature to match.
17545 * lread.c (hash_string): Use size_t, not int, for hash computation.
17546 Normally we prefer signed values; but hashing is special, because
17547 it's better to use unsigned division on hash table sizes so that
17548 the remainder is nonnegative. Also, size_t is the natural width
17549 for hashing into memory. The previous code used 'int', which doesn't
17550 retain enough info to hash well into very large tables.
17551 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
17553 * dbusbind.c: Don't possibly lose pointer info when converting.
17554 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
17555 Use XPNTR rather than XHASH, so that the high-order bits of
17556 the pointer aren't lost when converting through void *.
17558 * eval.c (Fautoload): Don't double-shift a pointer.
17560 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
17562 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
17564 * gnutls.c (DEF_GNUTLS_FN):
17565 * image.c (DEF_IMGLIB_FN): Make function pointers static.
17567 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
17569 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
17572 2011-05-05 Eli Zaretskii <eliz@gnu.org>
17574 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
17575 New version that can reserve upto 2GB of heap space.
17577 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
17579 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
17581 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
17583 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
17584 `gnutls_certificate_set_x509_key_file'.
17586 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
17588 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
17589 Update dependencies.
17591 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
17593 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
17594 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
17595 Remove unused parameter `fildes'.
17596 * process.c (read_process_output, send_process): Don't pass it.
17598 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
17600 Fix previous change: the library cache is defined in w32.c.
17601 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
17602 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
17604 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
17606 Implement dynamic loading of GnuTLS on Windows.
17608 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
17609 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
17610 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
17613 * gnutls.c (Qgnutls_dll): Define.
17614 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
17615 (gnutls_*): Declare function pointers.
17616 (init_gnutls_functions): New function to initialize function pointers.

17619 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
17620 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
17621 (emacs_gnutls_write, emacs_gnutls_read)
17622 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
17623 (Fgnutls_available_p): New function.
17624 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

17632 (w32_delayed_load): Move to w32.c.
17634 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
17636 * w32.c (QCloaded_from, Vlibrary_cache): Define.
17637 (w32_delayed_load): Move from image.c. When loading a library, record
17638 its filename in the :loaded-from property of the library id.
17639 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
17640 Initialize and staticpro them.
17641 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
17643 * process.c: Include lisp.h before w32.h, not after.
17644 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
17645 instead of gnutls_record_check_pending.
17647 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
17649 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
17651 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
17652 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
17655 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
17657 * xterm.c (x_set_frame_alpha): Do not set property on anything

17681 (wait_for_termination, interruptible_wait_for_termination):
17682 Move after wait_for_termination_1.
17684 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
17686 * sysdep.c (interruptible_wait_for_termination): New function
17687 which is like wait_for_termination, but allows keyboard
17690 * callproc.c (Fcall_process): Add (:file "file") as an option for
17692 (Fcall_process_region): Ditto.
17694 2011-04-30 Eli Zaretskii <eliz@gnu.org>
17696 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
17697 rather than `XVECTOR (FOO)->size'.
17699 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
17700 inttypes.h, as a gnulib replacement is used if it not available in
17703 2011-04-21 Eli Zaretskii <eliz@gnu.org>
17705 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
17706 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
17707 of MOST_POSITIVE_FIXNUM. (Bug#8528)
17709 * coding.c (coding_alloc_by_realloc): Error out if destination
17710 will grow beyond MOST_POSITIVE_FIXNUM.
17711 (decode_coding_emacs_mule): Abort if there isn't enough place in

17724 * window.c (window_scroll_line_based): Use a marker instead of
17725 simple variables to record original value of point. (Bug#7952)
17727 * doprnt.c (doprnt): Fix the case where a multibyte sequence
17728 produced by %s or %c overflows available buffer space. (Bug#8545)
17730 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
17732 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

17767 Improve `doprnt' and its usage. (Bug#8545)
17768 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
17769 `format_end'. Remove support for %l as a conversion specifier.
17770 Don't use xrealloc. Improve diagnostics when the %l size modifier
17771 is used. Update the commentary.
17773 * eval.c (verror): Simplify calculation of size_t.
17775 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
17778 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
17780 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
17783 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
17785 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
17786 This makes this file independent of the recent pseudovector change.
17788 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
17790 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
17792 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
17793 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
17794 Remove unused local.
17795 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
17797 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
17798 GCC 4.6.0 optimizes based on type-based alias analysis.
17799 For example, if b is of type struct buffer * and v of type struct
17800 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
17801 != &v->size, and therefore "v->size = 1; b->size = 2; return
17802 v->size;" must therefore return 1. This assumption is incorrect
17803 for Emacs, since it type-puns struct Lisp_Vector * with many other
17804 types. To fix this problem, this patch adds a new type struct
17805 vectorlike_header that documents the constraints on layout of vectors
17806 and pseudovectors, and helps optimizing compilers not get fooled
17807 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
17808 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
17809 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
17811 (XSETPVECTYPE): Rewrite in terms of new macro.
17812 (XSETPVECTYPESIZE): New macro, specifying both type and size.
17813 This is a bit clearer, and further avoids the possibility of
17814 undesirable aliasing.
17815 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
17816 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
17817 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
17818 since Lisp_Subr is a special case (no "next" field).
17819 (ASIZE): Now uses header.size rather than size.
17820 All previous uses of XVECTOR (foo)->size replaced to use this macro,
17821 to avoid the hassle of writing XVECTOR (foo)->header.size.
17822 (struct vectorlike_header): New type.
17823 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
17824 object, to help avoid aliasing.
17825 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
17826 (SUBRP): Likewise, since Lisp_Subr is a special case.
17827 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
17828 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
17829 (struct Lisp_Hash_Table): Combine first two members into a single
17830 struct vectorlike_header member. All uses of "size" and "next" members
17831 changed to be "header.size" and "header.next".
17832 * buffer.h (struct buffer): Likewise.
17833 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
17834 * frame.h (struct frame): Likewise.
17835 * process.h (struct Lisp_Process): Likewise.
17836 * termhooks.h (struct terminal): Likewise.
17837 * window.c (struct save_window_data, struct saved_window): Likewise.
17838 * window.h (struct window): Likewise.
17839 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
17840 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
17841 * buffer.c (init_buffer_once): Likewise.
17842 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
17844 * process.c (Fformat_network_address): Use local var for size,
17847 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
17849 Make the Lisp reader and string-to-float more consistent (Bug#8525)
17850 * data.c (atof): Remove decl; no longer used or needed.
17851 (digit_to_number): Move to lread.c.
17852 (Fstring_to_number): Use new string_to_number function, to be
17853 consistent with how the Lisp reader treats infinities and NaNs.
17854 Do not assume that floating-point numbers represent EMACS_INT
17855 without losing information; this is not true on most 64-bit hosts.
17856 Avoid double-rounding errors, by insisting on integers when
17857 parsing non-base-10 numbers, as the documentation specifies.
17858 * lisp.h (string_to_number): New decl, replacing ...
17859 (isfloat_string): Remove.
17860 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
17861 (read1): Do not accept +. and -. as integers; this
17862 appears to have been a coding error. Similarly, do not accept
17863 strings like +-1e0 as floating point numbers. Do not report
17864 overflow for integer overflows unless the base is not 10 which
17865 means we have no simple and reliable way to continue.
17866 Break out the floating-point parsing into a new
17867 function string_to_number, so that Fstring_to_number parses
17868 floating point numbers consistently with the Lisp reader.
17869 (digit_to_number): Move here from data.c. Make it static inline.
17870 (E_CHAR, EXP_INT): Remove, replacing with ...
17871 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
17872 (string_to_number): New function, replacing isfloat_string.
17873 This function checks for valid syntax and produces the resulting
17874 Lisp float number too. Rework it so that string-to-number
17875 no longer mishandles examples like "1.0e+". Use strtoumax,
17876 so that overflow for non-base-10 numbers is reported only when
17877 there's no portable and simple way to convert to floating point.
17879 * textprop.c (set_text_properties_1): Rewrite for clarity,
17880 and to avoid GCC warning about integer overflow.
17882 * intervals.h (struct interval): Use EMACS_INT for members
17883 where EMACS_UINT might cause problems. See
17884 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
17885 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
17886 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
17888 (offset_intervals): Tell GCC not to worry about length overflow
17889 when negating a negative length.
17891 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
17892 (overrun_check_free): Likewise.
17894 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
17895 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
17898 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
17899 (gnutls_make_error): Rename local to avoid shadowing.
17900 (gnutls_emacs_global_deinit): ifdef out; not used.
17901 (Fgnutls_boot): Use const for pointer to readonly storage.
17902 Comment out unused local. Fix pointer signedness problems.
17904 * lread.c (openp): Don't stuff size_t into an 'int'.
17905 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
17906 about possible signed overflow.
17908 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
17909 (GDK_KEY_g): Don't define if already defined.
17910 (xg_prepare_tooltip): Avoid pointer signedness problem.
17911 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
17913 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
17914 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
17916 * xfns.c (Fx_window_property): Simplify a bit,
17917 to make a bit faster and to avoid GCC 4.6.0 warning.
17918 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
17920 * fns.c (internal_equal): Don't assume size_t fits in int.
17922 * alloc.c (compact_small_strings): Tighten assertion a little.
17924 Replace pEd with more-general pI, and fix some printf arg casts.
17925 * lisp.h (pI): New macro, generalizing old pEd macro to other
17926 conversion specifiers. For example, use "...%"pI"d..." rather
17927 than "...%"pEd"...".
17928 (pEd): Remove. All uses replaced with similar uses of pI.
17929 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
17930 * alloc.c (check_pure_size): Don't overflow by converting size to int.
17931 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
17932 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
17933 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
17934 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
17935 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
17937 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
17938 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
17939 * print.c (safe_debug_print, print_object): Likewise.
17940 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
17942 Use pI instead of if-then-else-abort. Use %p to avoid casts,
17943 avoiding the 0 flag, which is not portable.
17944 * process.c (Fmake_network_process): Use pI to avoid cast.
17945 * region-cache.c (pp_cache): Likewise.
17946 * xdisp.c (decode_mode_spec): Likewise.
17947 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
17948 behavior on 64-bit hosts with printf arg.
17949 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
17950 (x_stop_queuing_selection_requests): Likewise.
17951 (x_get_window_property): Don't truncate byte count to an 'int'
17954 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
17955 here, since it parses constructs like leading '-' and spaces,
17956 which are not wanted; and it overflows with large numbers.
17957 Instead, simply match F[0-9]+, which is what is wanted anyway.
17959 * alloc.c: Remove unportable assumptions about struct layout.
17960 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
17961 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
17962 (allocate_vectorlike, make_pure_vector): Use the new macros,
17963 plus offsetof, to remove unportable assumptions about struct layout.
17964 These assumptions hold on all porting targets that I know of, but
17965 they are not guaranteed, they're easy to remove, and removing them
17966 makes further changes easier.
17968 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
17969 This doesn't fix a bug but makes the code clearer.
17970 (string_overrun_cookie): Now const. Use initializers that
17971 don't formally overflow signed char, to avoid warnings.
17972 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
17973 can cause Emacs to crash when string overrun checking is enabled.
17974 (allocate_buffer): Don't assume sizeof (struct buffer) is a
17975 multiple of sizeof (EMACS_INT); it need not be, if
17976 alignof(EMACS_INT) < sizeof (EMACS_INT).
17977 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
17979 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

17986 supposed to be handshaking. (Bug#8556)
17987 Reported by Paul Eggert <eggert@cs.ucla.edu>.
17989 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

17994 (handle_user_signal): Break into debugger when debug-on-event
17995 matches the current signal symbol.
17997 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
17999 * alloc.c (check_sblock, check_string_bytes)
18000 (check_string_free_list): Convert to standard C.
18002 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
18004 * w32.c (emacs_gnutls_push): Fix typo.
18006 2011-04-25 Eli Zaretskii <eliz@gnu.org>
18008 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
18009 "cast to pointer from integer of different size".
18011 Improve doprnt and its use in verror. (Bug#8545)
18012 * doprnt.c (doprnt): Document the set of format control sequences
18013 supported by the function. Use SAFE_ALLOCA instead of always
18016 * eval.c (verror): Don't limit the buffer size at size_max-1, that
18017 is one byte too soon. Don't use xrealloc; instead xfree and
18020 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
18022 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
18025 * gnutls.c: Renamed global_initialized to
18026 gnutls_global_initialized. Added internals for the
18027 :verify-hostname-error, :verify-error, and :verify-flags
18028 parameters of `gnutls-boot' and documented those parameters in the
18029 docstring. Start callback support.
18030 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
18031 unless a fatal error occurred. Call gnutls_alert_send_appropriate
18032 on error. Return error code.

18034 (emacs_gnutls_read): Likewise.
18035 (Fgnutls_boot): Return handshake error code.

18099 <char-direction-table>: Deleted.
18101 2011-04-23 Eli Zaretskii <eliz@gnu.org>
18103 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
18104 * doprnt.c: Include limits.h.
18105 (SIZE_MAX): New macro.
18106 (doprnt): Return a size_t value. 2nd arg is now size_t.
18107 Many local variables are now size_t instead of int or unsigned.
18108 Improve overflow protection. Support `l' modifier for integer
18109 conversions. Support %l conversion. Don't assume an EMACS_INT
18110 argument for integer conversions and for %c.
18112 * lisp.h (doprnt): Restore prototype.
18114 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
18115 $(SRC)/character.h.
18117 * Makefile.in (base_obj): Add back doprnt.o.
18119 * deps.mk (doprnt.o): Add back prerequisites.
18120 (callint.o): Depend on character.h.
18122 * eval.c (internal_lisp_condition_case): Include the handler
18123 representation in the error message.
18124 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
18125 when breaking from the loop.
18127 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
18129 * callint.c (Fcall_interactively): When displaying error message
18130 about invalid control letter, pass the character's codepoint, not
18131 a pointer to its multibyte form. Improve display of the character
18132 in octal and display also its hex code.
18134 * character.c (char_string): Use %x to display the (unsigned)
18135 codepoint of an invalid character, to avoid displaying a bogus
18138 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
18139 `error', not SYMBOL_NAME itself.
18141 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
18142 character arguments to `error'.
18144 * charset.c (check_iso_charset_parameter): Fix incorrect argument
18145 to `error' in error message about FINAL_CHAR argument. Make sure
18146 FINAL_CHAR is a character, and use %c when it is passed as
18147 argument to `error'.

18211 Define only if needed.
18213 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
18214 by pacifying GCC about it. Maybe it's time to retire it?
18215 * xfaces.c (USG, __TIMEVAL__): Likewise.
18217 * dispextern.h (struct redisplay_interface): Rename param
18218 to avoid shadowing.
18219 * termhooks.h (struct terminal): Likewise.
18220 * xterm.c (xembed_send_message): Likewise.
18222 * insdel.c (make_gap_smaller): Define only if
18223 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
18225 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
18228 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
18229 so that we aren't warned about unused symbols.
18231 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
18233 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).
18235 * xfns.c (x_real_positions): Mark locals as initialized.
18237 * xmenu.c (xmenu_show): Don't use uninitialized vars.
18239 * xterm.c: Fix problems found by static analysis with other toolkits.
18240 (toolkit_scroll_bar_interaction): Define and use only if USE_X_TOOLKIT.
18241 (x_dispatch_event): Declare static if USE_GTK, and
18242 define if USE_GTK || USE_X_TOOLKIT.
18243 (SET_SAVED_BUTTON_EVENT): Define only if USE_X_TOOLKIT || USE_GTK.

18683 * ccl.c (Vccl_program_table): Now static.
18684 (check_ccl_update): Remove; unused.
18686 * category.c (SET_CATEGORY_SET, set_category_set): Move here.
18687 * category.h: ... from here.
18688 * category.c (check_category_table, set_category_set): Now static.
18690 * casetab.c (Vascii_upcase_table, Vascii_eqv_table): Now static.
18691 * lisp.h: Remove these decls.
18693 * buffer.c (buffer_count): Remove unused var.
18695 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
18696 so that it's not optimized away.
18697 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
18698 * dispextern.h (bidi_dump_cached_states): Remove, since it's
18699 exported only to the debugger.
18701 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
18702 * atimer.h (run_all_atimers): Remove; not exported.
18704 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
18705 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
18706 was inaccessible from Lisp.
18707 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
18708 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
18710 alloc.c: Import and export fewer symbols, and remove unused items.
18711 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
18713 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
18714 it's not optimized away by whole-program optimization.
18715 (message_enable_multibyte, free_misc): Remove.
18716 (catchlist, handlerlist, mark_backtrace):
18717 Declare only if BYTE_MARK_STACK.
18718 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
18719 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
18720 (message_enable_multibyte): Remove decl.
18721 (free_misc, interval_free_list, float_block, float_block_index):
18722 (n_float_blocks, float_free_list, cons_block, cons_block_index):
18723 (cons_free_list, last_marked_index):
18725 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
18726 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
18727 (mark_backtrace): Define only if BYTE_MARK_STACK.
18728 * xdisp.c (message_enable_multibyte): Now static.
18730 Declare Lisp_Object Q* variables to be 'static' if not exported.
18731 This makes it easier for human readers (and static analyzers)
18732 to see whether these variables are used from other modules.
18733 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
18734 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
18735 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

18738 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
18739 * xmenu.c, xselect.c:
18740 Declare Q* vars static if they are not used in other modules.
18741 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
18742 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
18743 Remove decls of unexported vars.
18744 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
18746 * lisp.h (DEFINE_FUNC): Make sname 'static'.
18748 Make Emacs functions such as Fatom 'static' by default.
18749 This makes it easier for human readers (and static analyzers)
18750 to see whether these functions can be called from other modules.
18751 DEFUN now defines a static function. To make the function external
18752 so that it can be used in other C modules, use the new macro DEFUE.
18753 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
18754 (Finit_image_library):
18755 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
18756 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
18757 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
18758 Remove decls, since these functions are now static.
18759 (Funintern, Fget_internal_run_time): New decls, since these functions
18760 were already external.
18762 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
18763 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

18769 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
18770 Mark functions with DEFUE instead of DEFUN,
18771 if they are used in other modules.
18772 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
18773 decls for now-static functions.
18774 * buffer.h (Fdelete_overlay): Remove decl.
18775 * callproc.c (Fgetenv_internal): Mark as internal.
18776 * composite.c (Fremove_list_of_text_properties): Remove decl.

18783 * fileio.c (Fmake_symbolic_link): New forward static decl.
18784 * image.c (Finit_image_library): New forward static decl.
18785 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
18786 * intervals.h (Fprevious_property_change):
18787 (Fremove_list_of_text_properties): Remove decls.
18788 * keyboard.c (Fthis_command_keys): Remove decl.
18789 (Fcommand_execute): New forward static decl.

18810 2011-04-13 Eli Zaretskii <eliz@gnu.org>
18812 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
18813 when at ZV. (Bug#8487)
18815 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
18817 * charset.c (Fclear_charset_maps): Use xfree instead of free.

18820 * sound.c (sound_cleanup, alsa_close): Likewise.
18821 * termcap.c (tgetent): Likewise.

18823 * xsettings.c (read_and_apply_settings): Likewise.
18825 * alloc.c (overrun_check_malloc, overrun_check_realloc)
18826 (overrun_check_free): Protoize.
18828 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
18830 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
18831 since callers should never pass a negative size.
18832 Change the signature to match that of plain 'read' and 'write'; see
18833 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
18834 * lisp.h: Update prototypes of emacs_write and emacs_read.
18836 2011-04-11 Eli Zaretskii <eliz@gnu.org>
18838 * xdisp.c (redisplay_window): Don't try to determine the character
18839 position of the scroll margin if the window start point w->startp
18840 is outside the buffer's accessible region. (Bug#8468)
18842 2011-04-10 Eli Zaretskii <eliz@gnu.org>
18844 Fix write-region and its subroutines for buffers > 2GB.
18845 * fileio.c (a_write, e_write): Modify declaration of arguments and
18846 local variables to support buffers larger than 2GB.
18847 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
18849 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
18850 argument, local variables, and return value.
18852 * lisp.h: Update prototypes of emacs_write and emacs_read.
18854 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
18856 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
18858 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
18860 Fix more problems found by GCC 4.6.0's static checks.
18862 * xdisp.c (vmessage): Use a better test for character truncation.
18864 * charset.c (load_charset_map): <, not <=, for optimization,
18865 and to avoid potential problems with integer overflow.
18866 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
18867 * casetab.c (set_identity, shuffle): Likewise.
18868 * editfns.c (Fformat): Likewise.
18869 * syntax.c (skip_chars): Likewise.
18871 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
18872 This also lets GCC 4.6.0 generate slightly better loop code.
18874 * callint.c (Fcall_interactively): <, not <=, for optimization.
18875 (Fcall_interactively): Count the number of arguments produced,
18876 not the number of arguments given. This is simpler and lets GCC
18877 4.6.0 generate slightly better code.
18879 * ftfont.c: Distingish more carefully between FcChar8 and char.
18880 The previous code passed unsigned char * to a functions like
18881 strlen and xstrcasecmp that expect char *, which does not
18882 conform to the C standard.
18883 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
18884 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
18885 char * when the C standard requires it.
18887 * keyboard.c (read_char): Remove unused var.
18889 * eval.c: Port to Windows vsnprintf (Bug#8435).
18890 Include <limits.h>.
18891 (SIZE_MAX): Define if the headers do not.
18892 (verror): Do not give up if vsnprintf returns a negative count.
18893 Instead, grow the buffer. This ports to Windows vsnprintf, which
18894 does not conform to C99. Problem reported by Eli Zaretskii.
18895 Also, simplify the allocation scheme, by avoiding the need for
18896 calling realloc, and removing the ALLOCATED variable.
18898 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
18900 Remove invocations of doprnt, as Emacs now uses vsnprintf.
18901 But keep the doprint source code for now, as we might revamp it
18902 and use it again (Bug#8435).
18903 * lisp.h (doprnt): Remove.
18904 * Makefile.in (base_obj): Remove doprnt.o.
18905 * deps.mk (doprnt.o): Remove.
18907 error: Print 32- and 64-bit integers portably (Bug#8435).
18908 Without this change, on typical 64-bit hosts error ("...%d...", N)
18909 was used to print both 32- and 64-bit integers N, which relied on
18910 undefined behavior.
18911 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
18912 * lisp.h (error, verror): Mark as printf-like functions.
18913 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
18914 Report overflow in size calculations when allocating printf buffer.
18915 Do not truncate output string at its first null byte.
18916 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
18917 Truncate the output at a character boundary, since vsnprintf does not
18919 * charset.c (check_iso_charset_parameter): Convert internal
18920 character to string before calling 'error', since %c now has the
18922 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
18923 overflow when computing char to be passed to 'error'. Do not
18924 pass Lisp_Object to 'error'; pass the integer instead.
18925 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
18926 formatted with plain %d.
18928 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
18930 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
18932 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
18934 * xterm.c (x_catch_errors): Remove duplicate declaration.
18936 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
18938 * xdisp.c, lisp.h (message_nolog): Remove; unused.
18940 2011-04-10 Jim Meyering <meyering@redhat.com>
18942 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
18943 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
18944 return ssize_t not "int", and use size_t as the buffer length.
18945 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
18946 * gnutls.h: Update declarations.
18947 * process.c (read_process_output): Use ssize_t, to match.
18948 (send_process): Likewise.
18950 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
18952 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
18954 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
18956 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
18957 Use unsigned char, to match FcChar8 type definition.
18959 * xterm.c (handle_one_xevent):
18960 * xmenu.c (create_and_show_popup_menu):
18961 * xselect.c (x_decline_selection_request)
18962 (x_reply_selection_request): Avoid type-punned deref of X events.
18964 2011-04-09 Eli Zaretskii <eliz@gnu.org>
18966 Fix some uses of `int' instead of EMACS_INT.
18967 * search.c (string_match_1, fast_string_match)
18968 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
18969 (scan_buffer, find_next_newline_no_quit)
18970 (find_before_next_newline, search_command, Freplace_match)
18971 (Fmatch_data): Make some `int' variables be EMACS_INT.
18973 * xdisp.c (display_count_lines): 3rd argument and return value now
18974 EMACS_INT. All callers changed.
18975 (pint2hrstr): Last argument is now EMACS_INT.
18977 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
18978 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
18979 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
18980 (decode_coding_utf_16, decode_coding_emacs_mule)

18982 (decode_coding_ccl, decode_coding_charset)
18983 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
18984 (decode_coding_iso_2022, decode_coding_emacs_mule)
18985 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
18986 <char_offset, last_offset>: Declare EMACS_INT.

18990 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
18991 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
18993 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
18994 (encode_invocation_designation): Last argument P_NCHARS is now
18996 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
18997 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
18999 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
19002 * ccl.c (Fccl_execute_on_string): Declare some variables
19005 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
19007 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
19009 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
19011 * process.c (Fformat_network_address): Doc fix.
19013 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
19015 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
19017 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
19019 * keyboard.c (read_char): Call Lisp function help-form-show,
19020 instead of using internal_with_output_to_temp_buffer.
19021 (Qhelp_form_show): New var.
19022 (syms_of_keyboard): Use DEFSYM macro.
19024 * print.c (internal_with_output_to_temp_buffer): Function deleted.

19031 (list_processes_1): Delete.
19033 2011-04-06 Eli Zaretskii <eliz@gnu.org>
19035 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
19037 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
19039 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
19041 Fix more problems found by GCC 4.6.0's static checks.
19043 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
19045 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
19047 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
19049 * xdisp.c (vmessage): Mark as a printf-like function.
19051 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
19053 * sound.c (sound_warning): Don't crash if arg contains a printf format.
19055 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
19056 printf-like functions.

19058 to system-supplied API.
19060 * eval.c (Fsignal): Remove excess argument to 'fatal'.
19062 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
19063 This avoids several warnings with gcc -Wstrict-overflow.
19064 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
19065 directly, rather than having caller test rule sign. This avoids
19066 some unnecessary tests.
19067 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
19068 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
19069 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
19071 * xfont.c (xfont_text_extents): Remove var that was set but not used.
19072 (xfont_open): Avoid unnecessary tests.
19074 * composite.c (composition_gstring_put_cache): Use unsigned integer.

19083 by using the new macro.
19085 * textprop.c (set_text_properties_1): Change while to do-while,
19086 since the condition is always true at first.
19088 * intervals.c (graft_intervals_into_buffer): Mark var as used.
19089 (interval_deletion_adjustment): Return unsigned value.
19092 * process.c (list_processes_1, create_pty, read_process_output):

19119 * eval.c (funcall_lambda): Rename local to avoid shadowing.
19121 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
19122 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
19123 can always succeed if overflow has undefined behavior.
19125 * search.c (boyer_moore, wordify): Remove vars set but not used.
19126 (wordify): Omit three unnecessary tests.
19128 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
19129 All callers changed. This avoids the need for an unused var.
19131 * casefiddle.c (casify_region): Remove var that is set but not used.
19133 * dired.c (file_name_completion): Remove var that is set but not used.
19135 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
19137 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
19138 (Finsert_file_contents): Remove unnecessary code checking fd.
19140 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
19141 Check for integer overflow on size calculations.
19143 * buffer.c (Fprevious_overlay_change): Remove var that is set
19146 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
19147 Remove vars that are set but not used.
19148 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
19149 (timer_check_2): Mark vars as initialized.
19151 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
19153 * image.c (lookup_image): Remove var that is set but not used.
19154 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
19156 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
19157 that are set but not used.
19159 * xfns.c (make_invisible_cursor): Don't return garbage
19160 if XCreateBitmapFromData fails (Bug#8410).
19162 * xselect.c (x_get_local_selection, x_handle_property_notify):
19163 Remove vars that are set but not used.
19165 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
19166 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
19168 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
19169 Remove var that is set but not used.
19170 (scroll_bar_windows_size): Now size_t, not int.
19171 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
19172 Check for overflow.
19174 * xfaces.c (realize_named_face): Remove vars that are set but not used.
19175 (map_tty_color) [!defined MSDOS]: Likewise.
19177 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
19179 * coding.c: Remove vars that are set but not used.
19180 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
19181 All callers changed.
19182 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
19183 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
19184 (decode_coding_charset): Remove vars that are set but not used.
19186 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
19187 that is set but not used.
19189 * print.c (print_object): Remove var that is set but not used.
19191 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
19192 The gnulib version avoids calling malloc in the usual case,
19193 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
19194 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
19195 * filelock.c (current_lock_owner): Likewise.
19196 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
19197 * sysdep.c: Include allocator.h, careadlinkat.h.
19198 (emacs_no_realloc_allocator): New static constant.
19199 (emacs_readlink): New function.
19200 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
19201 ../lib/careadlinkat.h.
19203 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
19205 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
19206 first non-nil return value).

19217 (get_char_face_and_encoding): Remove parameter `multibyte_p',
19218 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

19220 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
19221 and thereabouts. All callers changed.
19222 (get_per_char_metric): Remove parameter `f', unused since
19223 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
19225 2011-04-02 Jim Meyering <meyering@redhat.com>
19227 do not dereference NULL upon failed strdup
19228 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
19229 (ns_get_family): Likewise.
19231 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
19233 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
19235 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
19237 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
19240 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
19242 Add lexical binding.
19244 * window.c (Ftemp_output_buffer_show): New fun.
19245 (Fsave_window_excursion):
19246 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
19248 * lread.c (lisp_file_lexically_bound_p): New function.
19249 (Fload): Bind Qlexical_binding.
19250 (readevalloop): Remove `evalfun' arg.
19251 Bind Qinternal_interpreter_environment.
19252 (Feval_buffer): Bind Qlexical_binding.
19253 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
19255 (syms_of_lread): Declare `lexical-binding'.
19257 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
19259 * keyboard.c (eval_dyn): New fun.
19260 (menu_item_eval_property): Use it.
19262 * image.c (parse_image_spec): Use Ffunctionp.
19264 * fns.c (concat, mapcar1): Accept byte-code-functions.
19266 * eval.c (Fsetq): Handle lexical vars.
19267 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
19268 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
19269 (FletX, Flet): Obey lexical binding.
19270 (Fcommandp): Handle closures.
19271 (Feval): New `lexical' arg.
19272 (eval_sub): New function extracted from Feval. Use it almost
19273 everywhere where Feval was used. Look up vars in lexical env.
19275 (Ffunctionp): Move from subr.el.
19276 (Ffuncall): Handle closures.
19277 (apply_lambda): Remove `eval_flags'.
19278 (funcall_lambda): Handle closures and new byte-code-functions.
19279 (Fspecial_variable_p): New function.
19280 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
19281 but without exporting it to Lisp.
19283 * doc.c (Fdocumentation, store_function_docstring):
19284 * data.c (Finteractive_form): Handle closures.
19286 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
19289 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
19291 (exec_byte_code): New function extracted from Fbyte_code to handle new
19292 calling convention for byte-code-functions. Add new byte-codes.
19294 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
19296 * alloc.c (Fmake_symbol): Init new `declared_special' field.
19298 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
19300 * xdisp.c (redisplay_internal): Fix prototype.
19302 2011-03-31 Eli Zaretskii <eliz@gnu.org>
19304 * xdisp.c (SCROLL_LIMIT): New macro.
19305 (try_scrolling): Use it when setting scroll_limit.
19306 Limit scrolling to 100 screen lines.
19307 (redisplay_window): Even when falling back on "recentering",
19308 position point in the window according to scroll-conservatively,
19309 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
19311 (try_scrolling): When point is above the window, allow searching
19312 as far as scroll_max, or one screenful, to compute vertical
19313 distance from PT to the scroll margin position. This prevents
19314 try_scrolling from unnecessarily failing when
19315 scroll-conservatively is set to a value slightly larger than the
19316 window height. Clean up the case of PT below the margin at bottom
19317 of window: scroll_max can no longer be INT_MAX. When aggressive
19318 scrolling is in use, don't let point enter the opposite scroll
19319 margin as result of the scroll.
19320 (syms_of_xdisp) <scroll-conservatively>: Document the
19321 threshold of 100 lines for never-recentering scrolling.
19323 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
19325 * dispextern.h (move_it_by_lines):
19326 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused

19328 (message_log_check_duplicate): Remove parameters `prev_bol' and
19329 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
19330 (redisplay_internal): Remove parameter `preserve_echo_area',
19331 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
19333 * indent.c (Fvertical_motion):
19334 * window.c (window_scroll_pixel_based, Frecenter):
19335 Don't pass `need_y_p' to `move_it_by_lines'.
19337 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
19339 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
19340 steal a few bits to be more compact.
19341 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
19342 Remove unneeded casts.
19344 * bytecode.c (Fbyte_code): CAR and CDR can GC.
19346 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
19348 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
19349 binding" message (bug#7967).
19351 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
19353 Fix more problems found by GCC 4.6.0's static checks.
19355 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
19356 Remove unused local var.
19358 * editfns.c (Fmessage_box): Remove unused local var.
19360 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
19361 (note_mode_line_or_margin_highlight, note_mouse_highlight):
19362 Omit unused local vars.
19363 * window.c (shrink_windows): Omit unused local var.
19364 * menu.c (digest_single_submenu): Omit unused local var.
19365 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
19366 Omit unused local var.
19368 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
19369 Don't assume string length fits in int.
19370 (keyremap_step, read_key_sequence): Use size_t for sizes.
19371 (read_key_sequence): Don't check last_real_key_start redundantly.
19373 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
19374 instead of alloca (Bug#8344).
19376 * eval.c (Fbacktrace): Don't assume nargs fits in int.
19377 (Fbacktrace_frame): Don't assume nframes fits in int.
19379 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
19381 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
19384 * term.c (produce_glyphless_glyph): Remove unnecessary test.
19386 * cm.c (calccost): Turn while-do into do-while, for clarity.
19388 * keyboard.c (syms_of_keyboard): Use the same style as later
19389 in this function when indexing through an array. This also
19390 works around GCC bug 48267.
19392 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
19394 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
19396 * chartab.c (sub_char_table_ref_and_range): Redo for slight
19397 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
19399 * keyboard.c, keyboard.h (num_input_events): Now size_t.
19400 This avoids undefined behavior on integer overflow, and is a bit
19401 more convenient anyway since it is compared to a size_t variable.
19403 Variadic C functions now count arguments with size_t, not int.
19404 This avoids an unnecessary limitation on 64-bit machines, which
19405 caused (substring ...) to crash on large vectors (Bug#8344).
19406 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
19407 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

19415 * fns.c (concat): Likewise.
19416 * frame.c (x_set_frame_parameters): Likewise.
19417 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
19418 0 if not found, not -1. All callers changed.
19420 * alloc.c (garbage_collect): Don't assume stack size fits in int.
19421 (stack_copy_size): Now size_t, not int.
19422 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
19424 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
19426 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
19427 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
19428 All callers changed.
19430 * lisp.h (multibyte_char_to_unibyte):
19431 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
19432 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

19443 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
19444 don't set the hook to nil, but remove the offending function instead.
19445 (Qcommand_hook_internal): Remove, unused.
19446 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
19447 Vcommand_hook_internal.
19449 * eval.c (enum run_hooks_condition): Remove.
19450 (funcall_nil, funcall_not): New functions.
19451 (run_hook_with_args): Call each function through a `funcall' argument.

19465 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
19466 All callers changed.
19468 * w32.c (_wsa_errlist): Use braces for struct initializers.
19470 * xdisp.c (string_buffer_position_lim): Remove parameter `w',

19588 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
19590 * w32term.c (x_set_glyph_string_clipping):
19591 Don't pass uninitialized region to CombineRgn.

19615 2011-03-23 Julien Danjou <julien@danjou.info>
19617 * term.c (Fsuspend_tty, Fresume_tty):
19618 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
19619 * window.c (temp_output_buffer_show):
19620 * insdel.c (signal_before_change):
19621 * frame.c (Fhandle_switch_frame):

19626 * callint.c (Fcall_interactively):
19627 * buffer.c (Fkill_all_local_variables):
19628 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
19630 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
19631 unconditionally since it does the check itself.
19633 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
19635 Fix more problems found by GCC 4.5.2's static checks.
19637 * coding.c (encode_coding_raw_text): Avoid unnecessary test
19638 the first time through the loop, since we know p0 < p1 then.
19639 This also avoids a gcc -Wstrict-overflow warning.
19641 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
19642 leading to a memory leak, possible in functions like
19643 load_charset_map_from_file that can allocate an unbounded number
19644 of objects (Bug#8318).
19646 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
19647 that could (at least in theory) be that large.
19649 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
19650 This is less likely to overflow, and avoids undefined behavior if
19651 overflow does occur. All callers changed. Use strtoul to scan
19652 for the unsigned long integer.
19653 (pint2hrstr): Simplify and tune code slightly.
19654 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
19656 * scroll.c (do_scrolling): Work around GCC bug 48228.
19657 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

19662 This also avoids a warning with gcc -Wstrict-overflow.
19664 * fileio.c (Fcopy_file): Report error if fchown or fchmod
19667 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
19669 * process.c (Fmake_network_process): Use socklen_t, not int,
19670 where POSIX says socklen_t is required in portable programs.
19671 This fixes a porting bug on hosts like 64-bit HP-UX, where
19672 socklen_t is wider than int (Bug#8277).
19673 (Fmake_network_process, server_accept_connection):
19674 (wait_reading_process_output, read_process_output):
19677 * process.c: Rename or move locals to avoid shadowing.

19687 Make tparam.h and terminfo.c consistent.
19688 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
19689 Include tparam.h instead, since it declares them.
19690 * cm.h (PC): Remove extern decl; tparam.h now does this.
19691 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
19692 * terminfo.c: Include tparam.h, to check interfaces.
19693 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
19694 (tparam): Adjust signature to match interface in tparam.h;
19695 this removes some undefined behavior. Check that outstring and len
19696 are zero, which they always are with Emacs.
19697 * tparam.h (PC, BC, UP): New extern decls.
19699 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
19700 (xftfont_open): Rename locals to avoid shadowing.
19702 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
19703 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
19704 (OTF_TAG_SYM): Omit macro if not needed.

19714 * composite.c (composition_compute_stop_pos): Rename local to
19716 (composition_reseat_it): Remove unused locals.
19717 (find_automatic_composition, composition_adjust_point): Likewise.
19718 (composition_update_it): Mark var as initialized.
19719 (find_automatic_composition): Mark vars as initialized,
19720 with a FIXME (Bug#8290).

19724 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
19725 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
19726 (BUF_DEC_POS): Be more systematic about renaming local temporaries
19727 to avoid shadowing.
19729 * textprop.c (property_change_between_p): Remove; unused.
19731 * intervals.c (interval_start_pos): Now static.
19733 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

19736 Rename locals to avoid shadowing.
19738 * sound.c (wav_play, au_play, Fplay_sound_internal):
19739 Fix pointer signedness.
19740 (alsa_choose_format): Remove unused local var.
19741 (wav_play): Initialize a variable to 0, to prevent undefined
19742 behavior (Bug#8278).
19744 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
19746 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
19748 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
19749 clobbering (Bug#8298).
19750 * sysdep.c (sys_subshell): Likewise.
19751 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
19753 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
19754 This should get cleaned up, so that child_setup has the
19755 same signature on all platforms.
19757 * callproc.c (call_process_cleanup): Now static.
19758 (relocate_fd): Rename locals to avoid shadowing.
19760 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
19762 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
19763 not to be necessary, and produces flickering.
19765 2011-03-20 Glenn Morris <rgm@gnu.org>
19767 * config.in: Remove file.
19769 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
19771 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
19772 are now in src/globals.h.
19773 (syms_of_minibuf): Remove spurious & from previous change.
19775 2011-03-20 Leo Liu <sdl.web@gmail.com>
19777 * minibuf.c (completing-read-function): New variable.
19778 (completing-read-default): Rename from completing-read.
19779 (completing-read): Call completing-read-function.
19781 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
19783 * xfaces.c (Fx_load_color_file):
19784 Read color file from absolute filename (bug#8250).
19786 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
19788 * makefile.w32-in: Update dependencies.
19790 2011-03-17 Eli Zaretskii <eliz@gnu.org>
19792 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

19799 (sigchld_handler): Now static.
19801 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
19802 That way, the code declares only the vars that it needs.
19803 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
19804 * s/cygwin.h (PTY_ITERATION): Likewise.
19805 * s/darwin.h (PTY_ITERATION): Likewise.

19812 (CONSTANTLIM): Remove; unused.
19813 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
19814 Define only if needed.
19816 * unexelf.c (unexec): Name an expression,
19817 to avoid gcc -Wbad-function-cast warning.
19818 Use a different way to cause a compilation error if anyone uses
19819 n rather than nn, a way that does not involve shadowing.
19820 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
19822 * deps.mk (unexalpha.o): Remove; unused.
19824 New file unexec.h, the (simple) interface for unexec (Bug#8267).
19825 * unexec.h: New file.
19826 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
19827 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
19828 Depend on unexec.h.
19829 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
19830 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
19831 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
19832 Change as necessary to match prototype in unexec.h.
19834 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid
19836 (back_comment, skip_chars): Mark vars as initialized.

19887 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
19888 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
19889 some of which prompt warnings from gcc -Wbad-function-cast.
19890 (Fformat_time_string, Fencode_time, Finsert_char):
19891 (Ftranslate_region_internal, Fformat):
19892 Rename or remove local vars to avoid shadowing.
19893 (Ftranslate_region_internal): Mark var as initialized.
19895 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
19898 * lisp.h (eassert): Check that the argument compiles, even if
19899 ENABLE_CHECKING is not defined.
19901 * data.c (Findirect_variable): Name an expression, to avoid
19902 gcc -Wbad-function-cast warning.

19914 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
19915 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
19917 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
19918 (GC_STRING_CHARS): Remove; not used.
19919 (Fmemory_limit): Cast sbrk's returned value to char *.
19921 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
19922 avoids undefined behavior in theory.

19927 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
19928 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
19929 to use the following functions instead of these macros.
19930 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
19931 EMACS_INT, since callers assume the returned value fits in int.
19932 (upcase1): Likewise, for UPCASE_TABLE.
19933 (uppercasep, lowercasep, upcase): New static inline functions.
19934 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

19939 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
19940 (regex_compile, re_search_2, re_match_2_internal):
19941 Remove unused local vars.
19942 (FREE_VAR): Rewrite so as not to use empty "else",
19943 which gcc can warn about.
19944 (regex_compile, re_match_2_internal): Mark locals as initialized.
19945 (RETALLOC_IF): Define only if needed.
19946 (WORDCHAR_P): Likewise. This one is never needed, but is used
19947 only in a comment talking about a compiler bug, so put inside
19948 the #if 0 of that comment.
19949 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
19950 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
19953 * search.c (boyer_moore): Rename locals to avoid shadowing.
19954 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
19955 (PREV_CHAR_BOUNDARY): Likewise.
19957 * search.c (simple_search): Remove unused var.
19959 * dired.c (compile_pattern): Move decl from here ...

19967 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
19968 Rename locals to avoid shadowing.
19969 (Fvertical_motion): Mark locals as initialized.
19971 * casefiddle.c (casify_object, casify_region): Now static.
19972 (casify_region): Mark local as initialized.
19974 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
19976 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
19977 New macros, so that the caller can use some names other than
19978 gcpro1, gcpro2, etc.
19979 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
19981 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
19982 argument, for consistency with GCPRO2_VAR, etc: it is now the
19983 prefix of the variable, not the variable itself. All uses
19985 * dired.c (directory_files_internal, file_name_completion):
19986 Rename locals to avoid shadowing.
19988 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
19989 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
19990 dired.c's scmp function, had undefined behavior.
19991 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
19992 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
19993 * buffer.h: ... to here, because these macros use current_buffer,
19994 and the new implementation with inline functions needs to have
19995 current_buffer in scope now, rather than later when the macros
19997 (downcase, upcase1): New static inline functions.
19998 (DOWNCASE, UPCASE1): Reimplement using these functions.
19999 This avoids undefined behavior in expressions like
20000 DOWNCASE (x) == DOWNCASE (y), which previously suffered
