1 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
3 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
4 This will cause a production Emacs to dump core instead of
7 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
9 * frame.c (make_frame): Do not set window's buffer to t.
10 * window.c (Fsplit_window_internal): Likewise. Previously it was
11 used to indicate that the window is being set up. Now we use
12 set_window_buffer for all new windows, so the condition in ...
13 (Fset_window_buffer): ... is always true and can be removed.
15 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
17 Convenient macro to check whether the buffer is hidden.
18 * buffer.h (BUFFER_HIDDEN_P): New macro.
19 * frame.c (make_frame): Use it. Adjust comment.
20 * buffer.c (candidate_buffer): New function.
21 (Fother_buffer, other_buffer_safely): Use it.
23 2012-12-06 Eli Zaretskii <eliz@gnu.org>
25 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
26 if the child process is still running. Instead, exit the wait
27 loop and return zero. (Bug#13086)
29 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
31 * frame.h (x_char_width, x_char_height): Remove prototypes.

38 (Fframe_char_height): Likewise with FRAME_LINE_HEIGHT.
39 * keyboard.c (command_loop_1): Remove prototype.
40 (command_loop_2, top_level_1): Add static to match prototype.
42 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
44 Fix a recently-introduced delete-process race condition.
45 * callproc.c, process.h (record_kill_process):
46 New function, containing part of the old call_process_kill.
47 (call_process_kill): Use it.
48 This does not change call_process_kill's behavior.
49 * process.c (Fdelete_process): Use record_kill_process to fix a
50 race condition that could cause Emacs to lose track of a child.
52 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
54 Avoid code duplication between prev_frame and next_frame.
55 * frame.c (candidate_frame): New function. Add comment.
56 (prev_frame, next_frame): Use it. Adjust comment.
58 2012-12-06 Eli Zaretskii <eliz@gnu.org>
60 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
61 fails, signal an error instead of continuing with an empty
63 Encode expanded temp file pattern before passing it to mkstemp or
66 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
67 Encode the file name before passing it to dostounix_filename, in
68 case it will downcase it (under w32-downcase-file-names).
71 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
73 Minor call-process cleanups.
74 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
75 at the same time as other platforms, to simplify analysis.
76 No need for fd0_volatile since we have synch_process_fd.
77 Avoid needless emacs_close; arg is always negative.
79 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
81 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
84 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
86 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
87 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
88 and mouse_face_hidden members to a bitfields.
89 * frame.h (struct frame): Remove set-but-not-used space_width member.
90 (FRAME_SPACE_WIDTH): Remove.
91 * nsterm.m, w32term.c, xterm.c: Adjust users.
92 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
93 member. Adjust users. Convert term_initted, delete_in_insert_mode,
94 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
95 members to a bitfields.
97 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
99 Don't let call-process be a zombie factory (Bug#12980).
100 Fixing this bug required some cleanup of the signal-handling code.
101 As a side effect, this change also fixes a longstanding rare race
102 condition whereby Emacs could mistakenly kill unrelated processes,
103 and it fixes a bug where a second C-g does not kill a recalcitrant
104 synchronous process in GNU/Linux and similar platforms.
105 The patch should also fix the last vestiges of Bug#9488,
106 a bug which has mostly been fixed on the trunk by other changes.
107 * callproc.c, process.h (synch_process_alive, synch_process_death)
108 (synch_process_termsig, sync_process_retcode):
109 Remove. All uses removed, to simplify analysis and so that
110 less consing is done inside critical sections.
111 * callproc.c (call_process_exited): Remove. All uses replaced
112 with !synch_process_pid.
113 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
114 These take the role of what used to be in unwind-protect arg.
116 (block_child_signal, unblock_child_signal):
117 New functions, to avoid races that could kill innocent-victim processes.
118 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
119 (call_process_kill): Record killed processes as deleted, so that
120 zombies do not clutter up the system. Do this inside a critical
121 section, to avoid a race that would allow the clutter.
122 (call_process_cleanup): Fix code so that the second C-g works again
123 on common platforms such as GNU/Linux.
124 (Fcall_process): Create the child process in a critical section,
125 to fix a race condition. If creating an asynchronous process,
126 record it as deleted so that zombies do not clutter up the system.
127 Do unwind-protect for WINDOWSNT too, as that's simpler in the
128 light of these changes. Omit unnecessary call to emacs_close
129 before failure, as the unwind-protect code does that.
130 * callproc.c (call_process_cleanup):
131 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
132 * process.c (record_deleted_pid): New function, containing
133 code refactored out of Fdelete_process.
134 (Fdelete_process): Use it.
135 (process_status_retrieved): Remove. All callers changed to use
137 (record_child_status_change): Remove, folding its contents into ...
138 (handle_child_signal): ... this signal handler. Now, this
139 function is purely a handler for SIGCHLD, and is not called after
140 a synchronous waitpid returns; the synchronous code is moved to
141 wait_for_termination. There is no need to worry about reaping
142 more than one child now.
143 * sysdep.c (get_child_status, child_status_changed): New functions.
144 (wait_for_termination): Now takes int * status and bool
145 interruptible arguments, too. Do not record child status change;
146 that's now the caller's responsibility. All callers changed.
147 Reimplement in terms of get_child_status.
148 (wait_for_termination_1, interruptible_wait_for_termination):
149 Remove. All callers changed to use wait_for_termination.
150 * syswait.h: Include <stdbool.h>, for bool.
151 (record_child_status_change, interruptible_wait_for_termination):
153 (record_deleted_pid, child_status_changed): New decls.
154 (wait_for_termination): Adjust to API changes noted above.
156 * bytecode.c, lisp.h (Qbytecode): Remove.
157 No longer needed after 2012-11-20 interactive-p changes.
159 2012-12-03 Eli Zaretskii <eliz@gnu.org>
161 * xdisp.c (redisplay_window): If the cursor is visible, but inside
162 the scroll margin, move point outside the margin. (Bug#13055)
164 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
166 * gtkutil.c (my_log_handler): New function.
167 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
169 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
171 * lisp.h (modify_region): Rename to...
172 (modify_region_1): ...new prototype.
173 * textprop.c (modify_region): Now static. Adjust users.
174 * insdel.c (modify_region): Rename to...
175 (modify_region_1): ...new function to work with current buffer.
176 Adjust comment and users. Use true and false for booleans.
178 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
180 * alloc.c (free_save_value): New function.
181 (safe_alloca_unwind): Use it.
182 * lisp.h (free_save_value): New prototype.
183 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
185 (save_excursion_restore): Adjust to match saved data structure.
186 Use free_save_value to offload some work from GC. Drop obsolete
189 2012-12-03 Chong Yidong <cyd@gnu.org>
191 * fileio.c (Vauto_save_list_file_name): Doc fix.
193 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
195 * w32fns.c: Remove prototype of atof.
196 (syspage_mask): Declared DWORD_PTR, for compatibility with 64-bit
198 (file_dialog_callback): Declared UINT_PTR.
200 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
203 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
204 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
207 2012-12-03 Glenn Morris <rgm@gnu.org>
209 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
211 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
213 Fix xpalloc confusion after memory is exhausted.
214 * alloc.c (xpalloc): Comment fix.
215 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
216 and signals an error, do not clear charset_table_size, as
217 charset_table is still valid.
218 * doprnt.c (evxprintf): Clear *BUF after freeing it.
220 Use execve to avoid need to munge environ (Bug#13054).
221 * callproc.c (Fcall_process):
222 * process.c (create_process):
223 Don't save and restore environ; no longer needed.
224 * callproc.c (child_setup):
225 Use execve, not execvp, to preserve environ.
227 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
229 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
231 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
233 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
234 display for sliced images (Bug#10500).
236 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
238 2012-11-30 Juanma Barranquero <lekktu@gmail.com>

241 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
243 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
245 * xdisp.c (window_outdated): Remove eassert since it hits
246 some suspicious corner cases (see Bug#13007 and Bug#13012).
247 (mode_line_update_needed): New function.
248 (redisplay_internal, redisplay_window): Use it.
249 (ensure_selected_frame): New function.
250 (redisplay_internal, unwind_redisplay): Use it.
251 (redisplay_internal): Move comment about buffer_shared...
252 (buffer_shared_and_changed): ...near to its real use.
254 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
256 * callproc.c (Fcall_process): Don't misreport vfork failure.
258 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
260 * callproc.c (Fcall_process): Fix vfork portability problems.
261 Do not assume that fd[0], count, filefd, and save_environ survive
262 vfork. Fix bug whereby wrong errno value could be reported for
263 pipe failure. Some minor cleanups, too, as follows. Move buf and
264 bufsize to the context where they're needed. Change new_argv to
265 be of type char **, as this is more convenient and avoids casts.
266 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
267 Now local constants, not macros.
269 2012-11-18 Kenichi Handa <handa@gnu.org>
271 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
272 for the variable "f".
274 2012-11-13 Kenichi Handa <handa@gnu.org>
276 * font.c (font_unparse_xlfd): Exclude special characters from the
277 generating XLFD name.

319 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
320 between bpos_covered and bpos_max. This fixes cursor display when
321 several display strings follow each other.
323 * .gdbinit (pgx): If the glyph's object is a string, display the
324 pointer to string data, rather than the value of the string object
325 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
327 * indent.c (Fvertical_motion): If the starting position is covered
328 by a display string, return to one position before that, to avoid
329 overshooting it inside move_it_to. (Bug#12930)
331 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>

357 (NAMLEN): Remove, replacing with ...
358 (dirent_namelen): New function. All uses changed. Use the GNU macro
359 _D_EXACT_NAMELEN if available, as it's faster than strlen.
360 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
361 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
362 * makefile.w32-in (DIR_H): Remove. All uses replaced with
364 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
365 * ndir.h: Rename to ../nt/inc/dirent.h.
366 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
367 Do not include <dirent.h>; no longer needed.

379 * msdos.c (IT_frame_up_to_date): Use it here...
380 * w32term.c (w32_frame_up_to_date): ...here...
381 * xterm.c (XTframe_up_to_date): ...and here...
382 * nsterm.m (ns_frame_up_to_date): ...but not here.
383 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
385 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
386 Do not check whether GC is in progress.

390 * xdisp.c (window_buffer_changed): New function.
391 (update_menu_bar, update_tool_bar): Use it to
392 simplify large 'if' statements.
393 (redisplay_internal): Generalize commonly used
394 'tail' and 'frame' local variables.
396 2012-11-22 Eli Zaretskii <eliz@gnu.org>
398 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
399 with Windows system header.

403 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
404 * alloc.c: Assume unistd.h exists.

426 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
427 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
428 Define for the MSVC compiler.
430 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
432 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
433 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
434 dostounix_filename. Prevents crashes down the road, because
435 dostounix_filename assumes it gets a unibyte string. Reported by
436 Michel de Ruiter <michel@sentient.nl>, see

487 * w32select.c: Include w32common.h before w32term.h, so that
488 windows.h gets included before w32term.h uses some of its
491 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
493 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
495 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
497 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
499 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
500 (ns_select): Return at once if events are held (Bug#12834).
502 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
504 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
505 Needed following 2012-10-20 change. (Bug#12902)
507 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
509 * w32proc.c (waitpid): Remove unused label get_result.
511 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
513 * makefile.w32-in (SYSWAIT_H): New macro.
514 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
515 ($(BLD)/sysdep.$(O)): Update dependencies.
517 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
519 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
520 * callproc.c (relocate_fd): Assume F_DUPFD.
521 * emacs.c, term.c (O_RDWR): Remove.
522 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
523 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
524 * nsterm.m: Assume <fcntl.h> exists.
525 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
526 (create_pty, Fmake_network_process, server_accept_connection)
527 (wait_reading_process_output, init_process_emacs):
529 (wait_reading_process_output): Put in a special case for WINDOWSNT
530 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
531 It's not clear this is needed, but it's a more-conservative change.
532 (create_process): Assume FD_CLOEXEC.
533 (create_process, create_pty): Assume O_NOCTTY.
534 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
535 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
536 Omit if not DOS_NT, since F_GETFL is not defined there.
537 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
538 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
540 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
541 lack it, since gnulib guarantees this.
542 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
544 2012-11-17 Eli Zaretskii <eliz@gnu.org>
546 * w32.c (faccessat): Pretend that directories have the execute bit
547 set. Emacs expects that, e.g., in files.el:cd-absolute.
549 * w32proc.c (create_child): Don't clip the PID of the child
550 process to fit into an Emacs integer, as this is no longer a
552 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
553 reaping only the process specified by PID argument, if that is
554 positive. Use PID instead of dead_child to know which process to
555 reap. Wait for the child to die only if WNOHANG is not in
557 (sys_select): Don't set dead_child.
559 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
560 as it is no longer needed.
562 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
564 (record_child_status_change): Remove the setting of
565 record_at_most_one_child for the !WNOHANG case.
567 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
569 Fix problems in ns port found by static checking.
570 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
571 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
572 not to process group.
573 (ns_select): Use emacs_write, not write, as that's more robust
574 in the presence of signals.
575 (fd_handler:): Check for read errors.
577 2012-11-16 Glenn Morris <rgm@gnu.org>
579 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
581 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
583 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
585 2012-11-16 Eli Zaretskii <eliz@gnu.org>
587 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
588 use the same value of thread handle.
589 (start_timer_thread): If the timer thread exited (due to error),
590 clean up by closing the two handles it used. Duplicate the caller
591 thread's handle here, so it gets duplicated only once, when
592 launching the timer thread. Set priority of the timer thread, not
594 (getitimer): Don't duplicate the caller thread's handle here.
597 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
599 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
602 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
604 Remove no-longer-used pty_max_bytes variable.
605 * process.c (pty_max_bytes): Remove; unused.
606 (send_process): Do not set it.
608 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
610 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
613 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
615 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
616 This follows up on the 2012-09-29 patch that removed indirection
617 for the 'function' field. Reported by Sergey Vinokurov in
618 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
620 2012-11-14 Eli Zaretskii <eliz@gnu.org>
622 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
623 different name, as the MS runtime does not have such a function,
624 and probably never will.) All callers changed. Ignore DIRFD
625 value if PATH is an absolute file name, to match Posix spec
626 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
629 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
631 * xdisp.c (echo_area_display, redisplay_internal):
632 Omit redundant check whether frame_garbaged is set.
634 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
636 Use faccessat, not access, when checking file permissions (Bug#12632).
637 This fixes a bug that has been present in Emacs since its creation.
638 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
639 which must set some sort of record. (Torek's bug report was against
640 a predecessor of GNU Emacs, but GNU Emacs happened to have the
641 same common flaw.) See Torek's Usenet posting
642 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
643 Posted: Fri Apr 8 14:18:56 1983.
644 * Makefile.in (LIB_EACCESS): New macro.
646 * callproc.c (init_callproc):
647 * charset.c (init_charset):
648 * fileio.c (check_existing, check_executable, check_writable)
650 * lread.c (openp, load_path_check):
651 * process.c (allocate_pty):
653 Use effective UID when checking permissions, not real UID.
654 * callproc.c (init_callproc):
655 * charset.c (init_charset):
656 * lread.c (load_path_check, init_lread):
657 Test whether directories are accessible, not merely whether they exist.
658 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
659 * fileio.c (check_existing, check_executable, check_writable)
661 Use symbolic names instead of integers for the flags, as they're
663 (check_writable): New arg AMODE. All uses changed.
664 Set errno on failure.
665 (Ffile_readable_p): Use faccessat, not stat + open + close.
666 (Ffile_writable_p): No need to call check_existing + check_writable.
667 Just call check_writable and then look at errno. This saves a syscall.
668 dir should never be nil; replace an unnecessary runtime check
669 with an eassert. When checking the parent directory of a nonexistent
670 file, check that the directory is searchable as well as writable, as
671 we can't create files in unsearchable directories.
672 (file_directory_p): New function, which uses 'stat' on most platforms
673 but faccessat with D_OK (for efficiency) if WINDOWSNT.
674 (Ffile_directory_p, Fset_file_times): Use it.
675 (file_accessible_directory_p): New function, which uses a single
676 syscall for efficiency.
677 (Ffile_accessible_directory_p): Use it.
678 * xrdb.c (file_p): Use file_directory_p.
679 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
680 * lread.c (openp): When opening a file, use fstat rather than
681 stat, as that avoids a permissions race. When not opening a file,
682 use file_directory_p rather than stat.
683 (dir_warning): First arg is now a usage string, not a format.
684 Use errno. All uses changed.
685 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
686 that merely introduced a race.
687 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
688 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
689 and similarly for the other O_* flags.
690 * w32.c (sys_faccessat): Rename from sys_access and switch to
691 faccessat's API. All uses changed.
692 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
693 (magic_db): Rename from magic_file_p.
694 (magic_db, search_magic_path): Return an XrmDatabase rather than a
695 char *, so that we don't have to test for file existence
696 separately from opening the file for reading. This removes a race
697 fixes a permission-checking problem, and simplifies the code.
699 (file_p): Remove; no longer needed.
701 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
703 Omit glyphs initialization at startup.
704 * dispnew.c (glyphs_initialized_initially_p): Remove.
705 (adjust_frame_glyphs_initially): Likewise. Adjust users.
706 (Fredraw_frame): Move actual code from here...
707 (redraw_frame): ...to here. Add eassert. Adjust comment.
708 (Fredraw_display): Use redraw_frame.
709 * xdisp.c (clear_garbaged_frames): Likewise.
711 2012-11-13 Eli Zaretskii <eliz@gnu.org>
713 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
714 passed to pint2str and pint2hrstr to be at most the size of the
715 frame's decode_mode_spec_buffer. This avoids crashes with very
716 large values of FIELD_WIDTH argument to decode_mode_spec.
719 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
721 Fix a race with verify-visited-file-modtime (Bug#12863).
722 Since at least 1991 Emacs has ignored an mtime difference of no
723 more than one second, but my guess is that this was to work around
724 file system bugs that were fixed long ago. Since the race is
725 causing problems now, let's remove that code.
726 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
727 whose time stamp is off by no more than a second. Insist that the
728 file time stamps match exactly.
730 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
732 * frame.h (struct frame): Convert external_tool_bar member to
733 1-bit unsigned bitfield.
734 * termhooks.h (struct terminal): Remove mouse_moved member since
735 all users are long dead. Adjust comment on mouse_position_hook.
737 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
739 Simplify by using FOR_EACH_FRAME here and there.
740 * frame.c (next_frame, prev_frame, other_visible_frames)
741 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
742 * w32term.c (x_window_to_scroll_bar): Likewise.
743 * window.c (window_list): Likewise.
744 * xdisp.c (x_consider_frame_title): Likewise.
745 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
746 * xfns.c (x_window_to_frame, x_any_window_to_frame)
747 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
748 * xmenu.c (menubar_id_to_frame): Likewise.
749 * xselect.c (frame_for_x_selection): Likewise.
750 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
751 (x_window_to_menu_bar): Likewise.
752 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
754 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
756 * data.c (Qdefalias_fset_function): Now static.
758 Another tweak to vectorlike_header change.
759 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
760 Remove, and replace all uses with ...
761 (next_in_free_list, set_next_in_free_list):
762 New functions, which respect C's aliasing rules better.
764 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
766 * window.c (list4i): Rename from 'quad'. All uses changed.
767 Needed because <sys/types.h> defines 'quad' on Solaris 10.
769 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
771 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
772 warning about mixing declarations and code in ISO C90.
774 2012-11-10 Martin Rudalics <rudalics@gmx.at>
776 * window.c (Fsplit_window_internal): Set combination limit of
777 new parent window to t iff Vwindow_combination_limit is t;
778 fixing a regression introduced with the change from 2012-09-22.
779 (Fset_window_combination_limit): Fix doc-string.
781 2012-11-10 Eli Zaretskii <eliz@gnu.org>
783 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
784 amount when the scroll margins are too large. When scrolling
785 backwards in the buffer, give up if cannot reach point or the
786 scroll margin within a reasonable number of screen lines.
787 Fixes point position in window under scroll-up/down-aggressively when
788 point is positioned many lines beyond the window top/bottom.
791 * ralloc.c (relinquish): If real_morecore fails to return memory
792 to the system, don't crash; instead, leave the last heap
793 unchanged and return. (Bug#12774)
795 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
797 * lisp.h (AUTOLOADP): New macro.
798 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
799 * data.c (Ffset): Remove special ad-advice-info handling.
800 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
802 (Finteractive_form): Simplify.
803 (Fquo): Don't insist on having at least 2 arguments.
804 (Qdefalias_fset_function): New var.
806 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
808 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
810 * nsfont.m (Qcondensed, Qexpanded): New variables.
811 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
812 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
814 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
816 Fix recently introduced crash on MS-Windows (Bug#12839).
817 * w32term.h (struct scroll_bar): Use convenient header.
818 (SCROLL_BAR_VEC_SIZE): Remove.
819 * w32term.c (x_scroll_bar_create): Use VECSIZE.
821 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
823 Tweak last vectorlike_header change.
824 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
825 vectorlike object on the free list. This is introduced to avoid
826 some (but not all) pointer casting and aliasing problems, see
827 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
828 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
830 (xvectype, xvecsize): Use them to examine Lisp_Object values.
832 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
834 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
835 been removed, so remove them here also.
837 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
839 * doc.c (Fdocumentation): Handle new property
840 dynamic-docstring-function to replace the old ad-advice-info.
842 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
844 * fns.c (Qeql, hashtest_eq): Now static.
846 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
848 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
849 * fns.c (hashfn_eq, hashfn_eql, sxhash):
850 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
851 * buffer.c (compare_overlays): Use XLI rather than XHASH.
853 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
855 Use same hash function for hashfn_profiler as for hash_string etc.
856 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
857 * lisp.h (sxhash_combine): New inline function, with the contents
858 of the old SXHASH_COMBINE.
859 * profiler.c (hashfn_profiler): Use it, instead of having a
860 special hash function containing a comparison that always yields 1.
862 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
864 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
865 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
866 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
869 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
871 * image.c (xpm_make_color_table_h): Fix compiler error because
872 make_hash_table changed.
874 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
876 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
878 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
880 Use ad-hoc comparison function for the profiler's hash-tables.
881 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
882 (make_log): Use them.
883 (handle_profiler_signal): Don't inhibit quit any longer since we don't
884 call Fequal any more.
885 (Ffunction_equal): New function.
886 (cmpfn_profiler, hashfn_profiler): New functions.
887 (syms_of_profiler): Initialize them.

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

897 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.
898 (syms_of_fns): Initialize them.

907 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
908 value of w32-scroll-lock-modifier is neither nil nor one of the
909 known key modifiers. (Bug#12806)
911 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
913 Shrink struct vectorlike_header to the only size field.
914 * lisp.h (enum pvec_type): Avoid explicit enum member values.
916 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
917 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
918 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
919 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
920 information from the vector header. Adjust comment.

935 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
936 (large_vectors): Change type to struct large_vector.
937 (allocate_vector_from_block): Simplify.
938 (PSEUDOVECTOR_NBYTES): Replace with...
939 (vector_nbytes): ...new function. Adjust users.
940 (sweep_vectors): Adjust processing of large vectors.
941 (allocate_vectorlike): Likewise.
942 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
943 Add easserts. Adjust XSETPVECTYPESIZE usage.
944 (allocate_buffer): Use BUFFER_PVEC_INIT.
945 (live_vector_p): Adjust to match large vector.
946 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
947 * buffer.h (struct buffer): Add next member.
948 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
950 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
951 * fns.c (internal_equal): Adjust to match enum pvec_type change.
952 (copy_hash_table): Adjust to match vector header change.
953 * lread.c (defsubr): Use XSETPVECTYPE.
954 * .gdbinit (xpr, xbacktrace): Adjust to match vector header change.
955 (xvectype): Likewise. Print PVEC_NORMAL_VECTOR for regular vectors.
956 (xvecsize): New command.
958 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
960 * keyboard.c (event_to_kboard): Do not dereference
961 frame_or_window field of SELECTION_REQUEST_EVENT
962 and SELECTION_CLEAR_EVENT events (Bug#12814).
963 * xterm.h (struct selection_input_event): Adjust comment.
965 2012-11-07 Eli Zaretskii <eliz@gnu.org>
967 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
968 such as Scroll Lock, if the respective keys are treated as
969 function keys, not as modifiers. This avoids destroying non-ASCII
970 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
972 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
974 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
976 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
978 Restore some duplicate definitions (Bug#12814).
979 This undoes part of the 2012-11-03 changes. Some people build
980 with plain -g rather than with -g3, and they need the duplicate
981 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
982 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
983 Define as macros, as well as as enums or as constants.
985 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
987 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
988 to keypad keys (Bug#12816).
990 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
992 Minor adjustments of recently-changed frame functions.
993 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
994 known to be a frame (we're in the FRAMEP branch).
995 * lisp.h (Qframep): Remove decl. frame.h declares this.
996 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
997 since they're meant for Lisp fixnum values.
999 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1001 * window.c (Fwindow_combination_limit): Revert to the only
1002 required argument and adjust docstring as suggested in
1003 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
1004 by Martin Rudalics <rudalics@gmx.at>.
1006 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1008 Widely used frame validity and checking functions.
1009 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
1010 * frame.c (decode_live_frame, decode_any_frame): New functions.
1011 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
1012 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
1013 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
1014 (Fframe_pointer_visible_p): Use decode_any_frame.
1015 (Fmake_frame_visible, Fmake_frame_invisible, Ficonify_frame)
1016 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
1017 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
1018 (Fframe_focus): Likewise. Allow zero number of arguments.
1020 (frame_buffer_list, frame_buffer_predicate): Remove.
1021 * lisp.h (frame_buffer_predicate): Remove prototype.
1022 * buffer.c (Fother_buffer): Use decode_any_frame.
1023 * xdisp.c (Ftool_bar_lines_needed): Likewise.
1024 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
1025 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
1026 (Fclose_font, Ffont_info): Use decode_live_frame.
1027 * fontset.c (check_fontset_name): Likewise.
1028 * terminal.c (Fframe_terminal): Likewise.
1029 * w32fns.c (check_x_frame): Likewise.
1030 * window.c (Fminibuffer_window, Fwindow_at)
1031 (Fcurrent_window_configuration): Likewise.
1032 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
1033 Likewise. Allow zero number of arguments. Adjust docstring.
1034 * dispnew.c (Fredraw_frame): Likewise.
1035 * xfaces.c (frame_or_selected_frame): Remove.
1036 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
1037 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
1038 (Fframe_face_alist): Use decode_live_frame.
1039 * xfns.c (check_x_frame): Likewise.
1041 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1043 * window.c (quad): New function.
1044 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
1045 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
1046 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
1047 (Fwindow_line_height): Use it.
1048 (Fwindow_fringes): Use list3.
1049 (Fwindow_scroll_bars): Use list4.
1050 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
1051 (Fwindow_combination_limit): Allow zero number of arguments.
1053 2012-11-05 Eli Zaretskii <eliz@gnu.org>
1055 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
1057 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
1058 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
1059 file descriptor 2 for standard error. (Bug#12805)
1061 2012-11-05 Chong Yidong <cyd@gnu.org>
1063 * process.c (wait_reading_process_output): Revert previous change.
1065 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
1067 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
1068 This removes code that has been obsolete since around 1990.
1069 * callproc.c (Fcall_process):
1071 * process.c (create_process):
1072 * term.c (dissociate_if_controlling_tty):
1073 Assume setsid exists.
1074 * callproc.c (child_setup): Assume setpgid exists and behaves as
1075 per POSIX.1-1988 or later.
1076 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
1077 * emacs.c (shut_down_emacs):
1078 * sysdep.c (sys_suspend, init_foreground_group):
1079 Assume getpgrp behaves as per POSIX.1-1998 or later.
1080 * msdos.c (setpgrp): Remove.
1081 (tcgetpgrp, setpgid, setsid): New functions.
1082 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
1083 * term.c (no_controlling_tty): Remove; unused.
1084 * w32proc.c (setpgrp): Remove.
1085 (setsid, tcgetpgrp): New functions.
1087 Simplify by assuming __fpending.
1088 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
1089 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
1090 Do not assume that __fpending's result fits in int.
1092 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
1094 Remove EMACS_OUTQSIZE+sleep hack.
1095 * dispnew.c (update_frame_1): Remove hack for terminals slower
1096 than 2400 bps, which throttled Emacs by having it sleep.
1097 This code hasn't worked since at least 2007, when the multi-tty stuff
1098 was added, and anyway those old terminals are long dead.
1099 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
1100 without the dispnew.c change, as dispnew.c doesn't include systty.h.
1102 Fix data-loss with --version (Bug#9574).
1103 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
1104 as we can't assume that emacs_strerror is initialized, and strerror
1105 is good enough here.
1106 (main): Invoke atexit earlier, to catch earlier instances of
1107 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
1109 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
1111 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
1112 (keyDown): Remap keypad keys to X11 virtual key codes.
1114 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
1116 Fix data-loss with --batch (Bug#9574).
1117 * emacs.c: Include <close-stream.h>.
1118 (close_output_streams): New function.
1119 (main): Pass it to atexit, so that Emacs closes stdout and stderr
1120 and handles errors appropriately.
1121 (Fkill_emacs): Don't worry about flushing, as close_output_stream
1124 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
1125 The symptom is a diagnostic "GLib-WARNING **: In call to
1126 g_spawn_sync(), exit status of a child process was requested but
1127 SIGCHLD action was set to SIG_IGN and ECHILD was received by
1128 waitpid(), so exit status can't be returned." The diagnostic
1129 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
1130 The real bug is a race condition between Emacs and glib: Emacs
1131 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
1132 so that glib can't find it. Work around the bug by invoking
1133 waitpid only on subprocesses that Emacs itself creates.
1134 * process.c (create_process, record_child_status_change):
1135 Don't use special value -1 in pid field, as the caller now must
1136 know the pid rather than having the callee infer it.
1137 The inference was sometimes incorrect anyway, due to another race.
1138 (create_process): Set new 'alive' member if child is created.
1139 (process_status_retrieved): New function.
1140 (record_child_status_change): Use it.
1141 Accept negative 1st argument, which means to wait for the
1142 processes that Emacs already knows about. Move special-case code
1143 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
1144 processes that have already been waited for, by testing and
1145 clearing new 'alive' member.
1146 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
1147 now does this internally.
1148 (handle_child_signal): Let record_child_status_change do all
1149 the work, since we do not want to reap all exited child processes,
1150 only the child processes that Emacs itself created.
1151 * process.h (Lisp_Process): New boolean member 'alive'.
1153 Omit duplicate definitions no longer needed with gcc -g3.
1154 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
1155 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
1156 Define only as macros. There's no longer any need to also define
1157 these symbols as enums or as constants, since we now assume
1158 gcc -g3 when debugging.
1160 2012-11-03 Eli Zaretskii <eliz@gnu.org>
1162 * lisp.mk: Adjust comments to the fact that term/internal is now
1163 loaded from loadup.el.
1165 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
1166 (msdos_fatal_signal): New function.
1167 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
1170 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
1171 for GCC versions before 4.
1172 (emacs_raise): Define to call msdos_fatal_signal.
1174 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
1175 iterator when starting in the middle of a display or overlay
1178 2012-11-03 Chong Yidong <cyd@gnu.org>
1180 * process.c (wait_reading_process_output): Clean up the last
1183 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
1185 * process.c (wait_reading_process_output): Avoid a race condition
1186 with SIGIO delivery (Bug#11536).
1188 2012-11-03 Chong Yidong <cyd@gnu.org>
1190 * buffer.c (cursor_type): Untabify docstring.
1192 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1194 * frame.h (struct frame): Drop can_have_scroll_bars member
1195 which is meaningless for a long time. Adjust comments.
1196 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
1197 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
1199 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1201 * window.c (decode_next_window_args): Update window arg after
1202 calling decode_live_window and so fix crash reported at
1203 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
1204 by Juanma Barranquero <lekktu@gmail.com>.
1205 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
1206 * font.c (Ffont_at): Likewise.
1208 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
1210 * widget.c (resize_cb): New function.
1211 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
1212 (EmacsFrameResize): Check if all is up to date before changing frame
1215 2012-11-02 Eli Zaretskii <eliz@gnu.org>
1217 Implement backtrace output for fatal errors on MS-Windows.
1218 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
1219 (BACKTRACE_LIMIT_MAX): New macro.
1220 (w32_backtrace): New function.
1221 (emacs_abort): Use w32_backtrace when the user chooses not to
1222 attach a debugger. Update the text of the abort dialog.
1224 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1226 Window-related stuff cleanup here and there.
1227 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
1228 Use decode_any_window.
1229 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
1230 * xdisp.c (Fformat_mode_line): Likewise.
1231 * font.c (Ffont_at): Use decode_live_window.
1232 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
1233 * window.c (decode_next_window_args): Likewise.
1234 (decode_any_window): Remove static.
1235 * window.h (decode_any_window): Add prototype.
1236 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
1237 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
1240 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1242 Remove pad from struct input_event.
1243 * termhooks.h (struct input_event): Remove padding field.
1245 * keyboard.c (event_to_kboard): Simplify because frame_or_window
1246 member is never cons for a long time. Adjust comment.
1247 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
1248 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
1249 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
1250 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
1252 2012-11-01 Eli Zaretskii <eliz@gnu.org>
1254 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
1256 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
1258 Fix crash when using Emacs as commit editor for git (Bug#12697).
1259 * callproc.c (setpgrp): Remove macro, as we now use setpgid
1260 and it is configured in conf_post.h.
1261 (Fcall_process): Don't invoke both setsid and setpgid; the former
1262 is enough, if it exists.
1263 * callproc.c (Fcall_process, child_setup):
1264 * process.c (create_process): Use setpgid.
1265 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
1267 * dispnew.c (init_display): Initialize the foreground group
1268 if we are running a tty display.
1269 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
1270 * lisp.h (init_foreground_group): New decl.
1271 * sysdep.c (inherited_pgroup): New static var.
1272 (init_foreground_group, tcsetpgrp_without_stopping)
1273 (narrow_foreground_group, widen_foreground_group): New functions.
1274 (init_sys_modes): Narrow foreground group.
1275 (reset_sys_modes): Widen foreground group.
1277 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
1279 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
1281 2012-10-31 Martin Rudalics <rudalics@gmx.at>
1283 * minibuf.c (read_minibuf): Restore current buffer since
1284 choose_minibuf_frame calling Fset_frame_selected_window may
1285 change it (Bug#12766).
1287 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
1289 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
1291 2012-10-30 Kenichi Handa <handa@gnu.org>
1293 * font.c (Ffont_at): If WINDOW is specified and it is not
1294 displaying the current buffer, signal an error.
1296 2012-10-29 Daniel Colascione <dancol@dancol.org>
1298 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
1299 In preparation for fixing bug#12739, move these functions from
1302 * coding.h, coding.c: ... to here, and compile them only when
1303 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
1304 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
1306 2012-10-28 Eli Zaretskii <eliz@gnu.org>
1308 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
1309 (timer_loop, getitimer, setitimer): Use it instead of
1310 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
1312 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
1315 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
1317 * nsterm.m (NO_APPDEFINED_DATA): New define.
1318 (last_appdefined_event_data): New variable
1319 (last_appdefined_event): Remove.
1320 (ns_select): Initialize t from last_appdefined_event_data instead
1321 of [last_appdefined_event data1].
1322 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
1323 remove last_appdefined_event (Bug#12698).
1325 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
1327 * frame.c (x_set_font): Catch internal error.
1329 2012-10-27 Eli Zaretskii <eliz@gnu.org>
1331 Avoid overflow in w32 implementation of interval timers.
1332 When possible, for ITIMER_PROF count only times the main thread
1334 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
1335 'volatile ULONGLONG' types. All the other data which was
1336 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
1337 (GetThreadTimes_Proc): New typedef.
1338 (w32_get_timer_time): New function, returns a suitable time value
1340 (timer_loop): Enter critical section when accessing ULONGLONG
1341 values of the itimer_data struct, as these accesses are no longer
1342 atomic. Call 'w32_get_timer_time' instead of 'clock'.
1343 Remove unused variable.
1344 (init_timers): Initialize s_pfn_Get_Thread_Times.
1345 (start_timer_thread): Don't assign itimer->caller_thread here.
1346 (getitimer): Assign itimer->caller_thread here.
1347 (setitimer): Always call getitimer to get the value of ticks_now.
1348 (sys_spawnve): Avoid compiler warning about format mismatch.
1350 2012-10-26 Eli Zaretskii <eliz@gnu.org>
1352 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
1353 mouse movement events if the menu bar is active. This avoids
1354 producing a busy "hour-glass" cursor by Windows if the mouse
1355 pointer is positioned over a tooltip shown for some menu item.
1357 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
1359 Don't assume process IDs fit in int.
1360 * emacs.c (shut_down_emacs) [!DOS_NT]:
1361 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
1362 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
1363 Use pid_t, not int, to store process IDs, as 'int'
1364 is not wide enough on a few platforms (e.g., AIX and IRIX).
1366 2012-10-23 Kenichi Handa <handa@gnu.org>
1368 The following change is to make face-font-rescale-alist work
1369 correctly for non-ASCII fonts.
1371 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
1372 (font_open_for_lface): Handle Vface_font_rescale_alist.
1374 2012-10-23 Chong Yidong <cyd@gnu.org>
1376 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
1378 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
1380 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
1382 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
1384 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
1387 2012-10-21 Glenn Morris <rgm@gnu.org>
1389 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
1391 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
1393 Port to OpenBSD 5.1.
1394 * frame.c (Fmouse_position, Fmouse_pixel_position):
1395 * xdisp.c (produce_stretch_glyph):
1396 Declare local vars only when they're needed.
1397 This is clearer and avoids a warning on OpenBSD about unused vars.
1398 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.

1875 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
1876 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
1877 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
1878 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
1879 now a supported configuration.
1881 * Makefile.in: consolidate image variables into LIBIMAGE; add
1882 W32_OBJ and W32_LIBS. Compile new files.
1885 (_DebPrint) declare tracing facility for W32 debugging. We need
1886 to unify tracing later.
1888 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
1889 unconditional use of W32 Unicode functions. Cygwin runs only on
1890 100% Unicode operating systems.
1892 * cygw32.c: New file. Define Cygwin-specific facilities.
1893 (Fcygwin_convert_path_to_windows)
1894 (Fcygwin_convert_path_from_windows): New user functions for
1895 accessing Cygwin path-munging routines.
1897 * cygw32.h: New file.
1898 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
1899 UTF-16LE strings temporarily inside non-Lisp-visible string
1902 (w32_strerror): Just what it says on the tin.
1904 * emacs.c: Make the NS fork-then-exec code for daemon-launching
1905 also run for Cygwin; both systems have the same problem with using
1906 GUI facilities in a forked child. Also call syms_of_cygw32,
1907 syms_of_w32select in correct places.
1909 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
1910 needs fork-then-exec for daemon launching.
1912 * font.h: Include frame.h.
1914 * image.c: Use the image library cache machinery only when we're
1915 compiling for native WINDOWSNT; Cygwin can use shared libraries
1916 like any other Unixlike system.
1918 * keyboard.c: Clarify a comment regarding the input loop.
1920 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
1921 functions directly instead of trying to detect at runtime that our
1922 host operating system supports them. We make this change for two
1923 reasons: Cygwin lacks support for the multibyte character
1924 conversion functions used by the legacy menu code, and Cygwin
1925 never needs to rely on non-Unicode APIs.
1927 * unexw32.c (hinst): Declare extern.
1929 * w32.c: Change header order;
1930 (w32_strerror): Move to w32fns.c because we need it for
1931 non-WINDOWSNT builds.
1933 * w32.h: Add #error macro to make sure we don't include w32.h for
1934 Cygwin builds. Remove w32select declarations.
1936 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
1937 w32fns.c. w32console.c is WINDOWSNT-only.
1939 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
1940 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
1942 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
1943 (w32_major_version, w32_minor_version, w32_build_number)
1944 (os_subtype, sound_type): Define here
1945 (w32_defined_color): Make color parameter const for consistency
1946 with other _defined_color functions.
1947 (w32_createwindow): Unconditionally call w32_init_class instead of
1948 doing so only when hprevinst is non-NULL. Plumbing hprevinst
1949 through the code is complex and unnecessary because class
1950 registration is practically free.
1951 (w32_name_of_message): New EMACSDEBUG-only function.
1952 (Fset_message_beep): Move here
1953 (Fx_open_connection): Require that the display name for Windows be
1954 "w32" for consistency, emacsclient disambiguation, and maybe, one
1955 day, multi-window-system support.
1956 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
1957 Cygwin files for W32 GUI facilities, since these clearly don't
1958 expect Cygwin names.
1959 (_DebPrint): Define.
1960 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
1961 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
1962 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
1963 (w32_last_error): Remove.
1965 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
1967 * w32heap.c (syspage_mask): Declare here.
1968 (cache_system_info): Remove.
1970 * w32inevt.c (faked_key): Define globally, not statically.
1971 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
1972 (w32_console_toggle_lock_key): Move to w32fns.c.
1974 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
1976 * w32proc.c (_DebPrint): Move to w32fns.c.
1977 * w32select.c: Include string.h, stdio.h for Cygwin.
1978 * w32select.h: New File.
1980 * w32term.c: Include io.h for non-CYGWIN builds; needed for
1982 (w32_message_fd): New variable. Under Cygwin, holds the file
1983 descriptor the system used to tell us about pending thread
1986 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
1987 that prevented compilation under non-WINDOWSNT systems.
1989 (w32_initialize): Open /dev/windows and assign it to
1990 w32_message_fd. Provide w32 feature.
1992 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
1993 (WM_EMACS_INPUT_READY): add.
1994 (prepend_msg, w32_message_fd): Declare globally.
1997 (keyboard_handle): Use only when WINDOWSNT.
1998 (notify_msg_ready): New function. Posts a message to the main
1999 thread's message queue under CYGWIN, which wakes up the main
2000 thread from select(2) by making the /dev/windows file descriptor
2001 ready. Under WINDOWSNT, it sets an event the same way the old
2004 (post, prepend_msg): Actually call notify_msg_ready instead of
2005 setting the input event directly.
2007 2012-10-07 Eli Zaretskii <eliz@gnu.org>
2009 * ralloc.c (relinquish): If a heap is ready to be relinquished,
2010 but it still has blocs in it, don't return it to the system,
2011 instead of aborting. (Bug#12402)
2013 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
2015 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
2017 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
2018 MAC_OS_X_VERSION_10_6.
2019 (syms_of_nsterm): Remove comment about Panther and above for
2021 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
2022 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
2023 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
2025 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
2026 MAC_OS_X_VERSION_10_4.
2028 * nsmenu.m (fillWithWidgetValue:): Remove code for <
2029 MAC_OS_X_VERSION_10_2.
2031 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
2033 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
2034 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
2036 * nsterm.m (ns_in_resize): Remove (Bug#12479).
2037 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
2038 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
2039 Remove ns_in_resize check.
2040 (ns_clear_frame_area): Remove resize handle code.
2042 * nsfns.m (ns_in_resize): Remove.
2043 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
2044 Remove ns_in_resize check.
2046 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
2048 Improve sys_siglist detection.
2049 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
2050 defined as a macro, as is done in Solaris.
2051 (sys_siglist_entries): New macro.
2052 (save_strsignal): Use it.
2053 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
2054 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
2056 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
2058 * nsfns.m (Fx_create_frame): Call x_default_parameter with
2059 fullscreen/Fullscreen.
2061 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
2062 tobar_height is new.
2064 * nsterm.m (x_make_frame_visible): Check for fullscreen.
2065 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
2066 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
2067 (windowDidResize:): Check for correct window if old style fullscreen.
2068 Capitalize word in comment. Remove incorrect comment.
2069 (initFrameFromEmacs:): tbar_height renamed tibar_height.
2070 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
2071 error in drawing background.
2072 (toggleFullScreen:): Remove comment. Rearrange calls.
2073 Set toolbar values to zero, save old height in tobar_height.
2074 Restore tool bar height when leaving fullscreen.
2075 (canBecomeMainWindow): New function.
2077 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
2079 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
2081 2012-10-05 Eli Zaretskii <eliz@gnu.org>
2083 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
2085 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
2086 that time stamps of directories could also be changed.
2087 Don't request the too broad GENERIC_WRITE, only the more restrictive
2088 FILE_WRITE_ATTRIBUTES access rights.
2090 * fileio.c (Fset_file_times): Special-case ignoring errors for
2091 directories only on MSDOS, not on MS-Windows.
2093 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
2095 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
2097 2012-10-04 Eli Zaretskii <eliz@gnu.org>
2099 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
2100 see whether CreateFile failed.
2102 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
2104 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
2105 to avoid similar races.
2106 * keyboard.c (pending_signals): Now bool, not int.
2108 Port timers to OpenBSD, plus check for timer failures.
2109 OpenBSD problem reported by Han Boetes.
2110 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
2112 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
2113 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
2114 like OpenBSD, which has timer_settime but does not declare it.
2115 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
2116 whether to use itimerspec-related primitives. All uses of
2117 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
2119 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2121 * profiler.c (handle_profiler_signal): Fix a malloc race
2122 that caused Emacs to hang on Fedora 17 when profiling Lisp.
2124 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
2126 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
2128 2012-10-02 Eli Zaretskii <eliz@gnu.org>
2130 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
2131 consistent with the change in return value of 'safe_strsignal'.
2133 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2135 Prefer plain 'static' to 'static inline' (Bug#12541).
2136 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
2137 (bidi_set_sor_type, bidi_push_embedding_level)
2138 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
2139 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
2140 (bidi_cache_search, bidi_cache_ensure_space)
2141 (bidi_cache_iterator_state, bidi_cache_find)
2142 (bidi_peek_at_next_level, bidi_set_paragraph_end)
2143 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
2144 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
2145 Now 'static', not 'static inline'.
2147 Count overruns when profiling; change units to ns.
2148 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
2149 Give extra weight to samples after overruns, to attempt to count
2150 the time more accurately.
2151 (setup_cpu_timer): Change sampling interval units from ms to ns, since
2152 the underlying primitives nominally do ns.
2153 (Fprofiler_cpu_start): Document the change. Mention that
2154 the sampling intervals are only approximate.
2156 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
2158 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
2160 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
2161 case for the special 0 coding-system.
2163 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
2164 (Fmake_overlay): Remove redundant tests.
2165 (fix_start_end_in_overlays): Remove redundant recentering.
2167 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
2169 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
2170 Update dependencies.
2172 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2174 Fix a malloc race condition involving strsignal.
2175 A signal can arrive in the middle of a malloc, and Emacs's signal
2176 handler can invoke strsignal, which can invoke malloc, which is
2177 not portable. This race condition bug makes Emacs hang on GNU/Linux.
2178 Fix it by altering the signal handler so that it does not invoke
2180 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
2181 * process.c (status_message): Use const pointer, in case strsignal
2182 is #defined to safe_strsignal.
2183 * sysdep.c (sys_siglist, init_signals): Always define and
2184 initialize a substitute sys_siglist if the system does not define
2185 one, even if HAVE_STRSIGNAL.
2186 (safe_strsignal): Rename from strsignal. Always define,
2187 using sys_siglist. Return a const pointer.
2188 * syssignal.h (safe_strsignal): New decl.
2189 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
2191 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2193 * w32proc.c (timer_loop): Fix code that waits for timer
2194 expiration, to avoid high CPU usage.
2196 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
2198 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
2199 (sweep_weak_table): Remove redundant prototypes.
2201 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
2203 * emacs.c: Move the inclusion of TERM_HEADER after including
2204 windows.h on WINDOWSNT. This avoids compilation problems with
2207 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2209 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
2210 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
2211 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
2212 as the previous version used 'void *'.
2214 * ralloc.c (ROUNDUP): Fix last change.
2215 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
2218 * w32proc.c <disable_itimers>: New static flag.
2219 (init_timers): Initialize it to zero, after creating the critical
2220 sections used by the timer threads.
2221 (term_timers): Set to 1 before deleting the critical sections.
2222 (getitimer, setitimer): If disable_itimers is non-zero, return an
2223 error indication without doing anything. Reported by Fabrice
2224 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
2225 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
2227 [!HAVE_SETITIMER]: Behave as the previous version that didn't
2230 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
2231 term_ntproc after all the other bookkeeping, to get timers working
2232 as long as possible.
2234 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2236 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
2237 Suggested by Juri Linkov in
2238 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
2240 Prefer plain 'static' to 'static inline' (Bug#12541).
2241 With static functions, modern compilers inline pretty well by
2242 themselves; advice from programmers often hurts as much as it helps.
2243 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
2244 this change shrinks the text size of the Emacs executable by 1.1%
2245 without affecting CPU significantly in my benchmark.

2539 (handle_profiler_signal): Rename from sigprof_handler_1,
2540 for consistency with other handlers. Do not check whether
2541 cpu_log is a hash-table if garbage collecting, since it

2544 for consistency with other handlers.
2545 (setup_cpu_timer): New function, with much of what used to be in

2547 Prefer timer_settime if available, and prefer
2548 thread cputime clocks, then process cputime clocks, then
2549 monotonic clocks, to the old realtime clock. Use make_timeval
2550 to round more-correctly when falling back to setitimer.
2551 (Fprofiler_cpu_start): Use it.
2552 (Fprofiler_cpu_stop): Prefer timer_settime if available.

2618 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
2619 Since this stuff is now private to charset.c, there's no need for
2620 a public macro and no need to inline by hand.

2779 * gnutls.c (gnutls_global_initialized, init_gnutls_functions)
2780 (emacs_gnutls_handle_error):
2781 * gtkutil.c (xg_check_special_colors, xg_prepare_tooltip)

2792 * gtkutil.c, w32term.c, xterm.c (x_wm_set_size_hint):
2793 * nsmenu.m (ns_update_menubar):
2794 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
2795 * xfns.c (Fx_show_tip) [USE_GTK]:
2796 Use bool for boolean.
2797 * gtkutil.c (xg_update_frame_menubar):
2798 * xmenu.c (update_frame_menubar):
2799 Return void, not int, since caller ignores return value.
2800 * gtkutil.c (xg_change_toolbar_position):
2803 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
2805 * makefile.w32-in (BLOCKINPUT_H): Remove.

2822 2012-09-23 Eli Zaretskii <eliz@gnu.org>
2824 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
2825 fatal_error_backtrace.
2827 * w32proc.c (sys_kill): Undo last change: don't do anything when
2828 invoked to deliver SIGABRT to our own process. This is now
2829 handled by emacs_raise.
2831 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
2833 * w32term.c (w32_read_socket): Remove leftover reference to
2834 interrupt_input_pending.
2836 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
2838 Do not use SA_NODEFER.
2839 Problem reported by Dani Moncayo in
2840 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
2842 * sysdep.c (emacs_abort): Do not reset signal handler.
2843 * emacs.c (terminate_due_to_signal): Reset signal handler here.
2844 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
2845 wanted even on POSIXish hosts, and it doesn't work on Windows.
2847 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
2849 * xterm.c (x_term_init): Call fixup_locale before and after calling
2850 gtk_init (Bug#12392).
2852 2012-09-23 Chong Yidong <cyd@gnu.org>
2854 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
2855 Vdynamic_library_alist.
2857 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
2858 (Fgnutls_available_p): Caller changed.
2860 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
2861 (Flibxml_parse_xml_region): Likewise.
2863 * dispextern.h (struct image_type): Remove arg from init function.
2865 * image.c (Finit_image_library, lookup_image_type)
2866 (define_image_type): Remove now-unneeded second arg.
2867 (init_xpm_functions, init_png_functions, init_jpeg_functions)
2868 (init_tiff_functions, init_gif_functions, init_svg_functions):
2869 Arglist and w32_delayed_load calling convention changed.
2870 (gs_type): Remove init_gs_functions; there is no such function.
2871 (valid_image_p, make_image): Fix caller to lookup_image_type.
2873 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
2875 Simplify and avoid signal-handling races (Bug#12471).
2877 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
2878 Avoid recursive loop if there's a fatal error in the function itself.
2879 * atimer.c (pending_atimers):
2880 * blockinput.h: Don't include "atimer.h"; no longer needed.
2881 (interrupt_input_pending): Remove. All uses removed.
2882 pending_signals now counts both atimers and ordinary interrupts.
2883 This is less racy than having three separate pending-signal flags.
2884 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
2886 Rename from their upper-case counterparts BLOCK_INPUT,
2887 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
2888 INPUT_BLOCKED_P, and turn into functions. All uses changed.
2889 This makes it easier to access volatile variables more accurately.
2890 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
2891 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
2892 that's more reliable if the code is buggy and sets
2893 interrupt_input_blocked to a negative value. All uses changed.
2894 * atimer.c (deliver_alarm_signal):
2895 Remove. No need to deliver this to the parent; any thread can
2896 handle this signal now. All uses replaced by underlying handler.
2897 * atimer.c (turn_on_atimers):
2898 * dispnew.c (handle_window_change_signal):
2899 * emacs.c (handle_danger_signal):
2900 * keyboard.c (kbd_buffer_get_event):
2901 Don't reestablish signal handler; not needed with sigaction.
2902 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
2904 Rework to avoid unnecessary accesses to volatile variables.
2905 (UNBLOCK_INPUT_TO): Now a function.
2906 (totally_unblock_input, unblock_input): New decls.
2907 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
2908 (init_data): Remove. Necessary stuff now done in init_signal.
2909 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
2910 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
2911 (fatal_error_code): Remove; no longer needed.
2912 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
2913 it doesn't always backtrace. All uses changed. No need to reset
2914 signal to default, since sigaction and/or die does that for us now.
2915 Use emacs_raise (FOO), not kill (getpid (), FOO).
2916 (main): Check more-accurately whether we're dumping.
2917 Move fatal-error setup to sysdep.c
2918 * floatfns.c: Do not include "syssignal.h"; no longer needed.
2919 * gtkutil.c (xg_get_file_name, xg_get_font):
2920 Remove no-longer-needed signal-mask manipulation.
2921 * keyboard.c, process.c (POLL_FOR_INPUT):
2922 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
2923 * keyboard.c (read_avail_input): Remove.
2924 All uses replaced by gobble_input.
2925 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
2926 (kbd_buffer_store_event_hold, gobble_input):
2927 (record_asynch_buffer_change) [USABLE_SIGIO]:
2928 (store_user_signal_events):
2929 No need to mess with signal mask.
2930 (gobble_input): If blocking input and there are terminals, simply
2931 set pending_signals to 1 and return. All hooks changed to not
2932 worry about whether input is blocked.
2933 (process_pending_signals): Clear pending_signals before processing
2934 them, in case a signal comes in while we're processing.
2935 By convention callers now test pending_signals before calling us.
2936 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
2937 New functions, to support changes to blockinput.h.
2938 (handle_input_available_signal): Now extern.
2939 (reinvoke_input_signal): Remove. All uses replaced by
2941 (quit_count): Now volatile, since a signal handler uses it.
2942 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
2943 All callers changed. Block SIGINT only if not already blocked.
2944 Clear sigmask reliably, even if Fsignal returns, which it can.
2945 Omit unnecessary accesses to volatile var.
2946 (quit_throw_to_read_char): No need to restore sigmask.
2947 * keyboard.c (gobble_input, handle_user_signal):
2948 * process.c (wait_reading_process_output):
2949 Call signal-handling code rather than killing ourselves.
2950 * lisp.h: Include <float.h>, for...
2951 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
2952 (pending_signals): Now volatile.
2953 (syms_of_data): Now const if IEEE floating point.
2954 (handle_input_available_signal) [USABLE_SIGIO]:
2955 (terminate_due_to_signal, record_child_status_change): New decls.
2956 * process.c (create_process): Avoid disaster if memory is exhausted
2957 while we're processing a vfork, by tightening the critical section
2959 (send_process_frame, process_sent_to, handle_pipe_signal)
2960 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
2962 (send_process): No need for setjmp/longjmp any more, since the
2963 SIGPIPE stuff is now gone. Instead, report an error if errno
2965 (record_child_status_change): Now extern. PID and W are now args.
2966 Return void, not bool. All callers changed.
2967 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
2968 Remove. All uses removed. This bug should be fixed now in a
2970 (wait_for_termination_1): Use waitpid rather than sigsuspend,
2971 and record the child status change directly. This avoids the
2972 need to futz with the signal mask.
2973 (process_fatal_action): Move here from emacs.c.
2974 (emacs_sigaction_flags): New function, containing
2975 much of what used to be in emacs_sigaction_init.
2976 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
2977 caught by emacs, to make races less likely.
2978 (deliver_process_signal): Rename from handle_on_main_thread.
2980 (BACKTRACE_LIMIT_MAX): Now at top level.
2981 (thread_backtrace_buffer, threadback_backtrace_pointers):
2983 (deliver_thread_signal, deliver_fatal_thread_signal):
2984 New functions, for more-accurate delivery of thread-specific signals.
2985 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
2986 (deliver_arith_signal): Handle in this thread, not
2987 in the main thread, since it's triggered by this thread.
2988 (maybe_fatal_sig): New function.
2989 (init_signals): New arg DUMPING so that we can be more accurate
2990 about whether we're dumping. Caller changed.
2991 Treat thread-specific signals differently from process-general signals.
2992 Block all signals while handling fatal error; that's safer.
2993 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
2995 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
2996 Ignore SIGPIPE unless batch.
2997 (emacs_backtrace): Output backtrace for the appropriate thread,
2998 which is not necessarily the main thread.
2999 * syssignal.h: Include <stdbool.h>.
3000 (emacs_raise): New macro.
3001 * xterm.c (x_connection_signal): Remove; no longer needed
3002 now that we use sigaction.
3003 (x_connection_closed): No need to mess with sigmask now.
3004 (x_initialize): No need to reset SIGPIPE handler here, since
3005 init_signals does this for us now.
3007 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3009 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
3010 background rect may be larger (Bug#12245).
3012 2012-09-23 Chong Yidong <cyd@gnu.org>
3014 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
3016 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3018 * .gdbinit: Just stop at fatal_error_backtrace.
3019 See Stefan Monnier's request in
3020 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
3021 Remove no-longer-used query of system type.
3023 2012-09-22 Chong Yidong <cyd@gnu.org>
3025 * search.c (Freplace_match): Doc fix (Bug#12325).
3027 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
3029 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
3030 (Fline_end_position): Doc fix.
3032 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
3034 2012-09-22 Chong Yidong <cyd@gnu.org>
3036 * dispextern.h (struct image_type): Add new slot, storing a type
3037 initialization function.
3039 * image.c (define_image_type): Call the image initializer function
3040 if it is defined. Arguments and return value changed.
3041 (valid_image_p, make_image): Callers changed.
3042 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
3043 (gif_type, imagemagick_type, svg_type, gs_type):
3044 Add initialization functions.
3045 (Finit_image_library): Call lookup_image_type.
3046 (CHECK_LIB_AVAILABLE): Macro deleted.
3047 (lookup_image_type): Call define_image_type here, rather than via
3048 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
3049 (syms_of_image): Move define_image_type calls for xbm_type and
3050 pbm_type to lookup_image_type.
3052 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3054 * keyboard.c (timer_check_2): Move calculation of 'timers' and
3055 'idle_timers' from here ...
3056 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
3057 lists, to avoid infloops when the timer does something stupid,
3058 like reinvoke itself with the same or smaller time-out.
3061 2012-09-22 Martin Rudalics <rudalics@gmx.at>
3063 * window.c (Fsplit_window_internal): Handle only Qt value of
3064 Vwindow_combination_limit separately.
3065 (Qtemp_buffer_resize): New symbol.
3066 (Vwindow_combination_limit): New default value.
3069 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3071 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
3072 the new overlay string. (Bug#10159)
3074 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3076 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
3077 or that fprintf is async-signal-safe. POSIX doesn't require
3080 2012-09-22 Chong Yidong <cyd@gnu.org>
3082 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
3085 2012-09-22 Kenichi Handa <handa@gnu.org>
3087 * composite.c (composition_reseat_it): Handle the case that a
3088 grapheme cluster is not covered by a single font (Bug#12352).
3090 2012-09-21 Chong Yidong <cyd@gnu.org>
3092 * image.c (define_image_type): Avoid adding duplicate types to
3093 image_types (Bug#12463). Suggested by Jörg Walter.
3095 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3097 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
3098 (print_load_command_name): Add case LC_DATA_IN_CODE.
3099 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
3101 2012-09-21 Glenn Morris <rgm@gnu.org>
3103 * eval.c (Frun_hook_with_args_until_success)
3104 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
3106 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
3108 * fileio.c (Ffile_selinux_context): Only call freecon when
3109 lgetfilecon succeeded.
3110 (Fset_file_selinux_context): Likewise. (Bug#12444)
3112 2012-09-21 Eli Zaretskii <eliz@gnu.org>
3114 * xdisp.c (try_window_reusing_current_matrix): Under bidi
3115 reordering, locate the cursor by calling set_cursor_from_row; if
3116 that fails, clear the desired glyph matrix before returning a
3117 failure indication to the caller. Fixes leaving garbled display
3118 when fast scrolling with a down-key. (Bug#12403)
3119 (compute_stop_pos_backwards): Fix a typo that caused crashes while
3120 scrolling through multibyte text.
3122 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
3124 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
3125 calling mark_vectorlike since that's the one that marks the window.
3126 (mark_discard_killed_buffers): Mark the final cdr.
3127 * window.h (struct window): Move prev/next_buffers to the
3128 non-standard fields.
3129 * window.c (make_window): Initialize prev/next_buffers manually.
3131 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
3133 Omit unused arg EXPECTED from socket hooks.
3134 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
3135 * nsterm.m (ns_term_init):
3136 * termhooks.h (struct terminal.read_socket_hook):
3137 * w32inevt.c (w32_console_read_socket):
3138 * w32term.c (w32_read_socket):
3139 * xterm.c (XTread_socket):
3140 Omit unused arg EXPECTED. All callers changed.
3141 (store_user_signal_events): Return void, not int, since callers no
3142 longer care about the return value. All uses changed.
3144 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
3146 * w32gui.h (XParseGeometry): Do not declare.
3148 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
3150 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
3151 Ignore 'expected'. See Eli Zaretskii in
3152 <http://bugs.gnu.org/12471#8> (last line).
3154 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
3155 (XParseGeometry): Now static. Substitute extremal values for
3156 values that are out of range.
3158 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
3160 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
3162 * nsfns.m (XParseGeometry): Remove.
3163 (Fx_create_frame): Call x_set_offset to correctly interpret
3164 top_pos in geometry.
3166 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
3167 (Fx_parse_geometry): If there is a space in string, call
3168 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
3170 2012-09-17 Eli Zaretskii <eliz@gnu.org>
3172 * search.c (scan_buffer): Use character positions in calls to
3173 region_cache_forward and region_cache_backward, not byte
3174 positions. (Bug#12196)
3176 * w32term.c (w32_read_socket): Set pending_signals to 1, like
3177 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
3179 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
3180 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
3181 emacs_blocked_malloc, now deleted.
3183 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
3185 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
3186 The workaround was for improving performance on Solaris 2.4, but
3187 is getting in the way now. Emacs will still work if someone is
3188 still running Solaris 2.4 in a museum somewhere; Sun dropped
3189 support for Solaris 2.4 in 2003.
3190 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
3191 * process.c (create_process) [HAVE_WORKING_VFORK]:
3192 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
3193 since Emacs no longer uses vfork on that platform.
3195 2012-09-17 Glenn Morris <rgm@gnu.org>
3197 * emacs.c: Use COPYRIGHT.
3199 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
3201 Remove configure's --without-sync-input option (Bug#12450).
3202 When auditing signal-handling in preparation for cleaning it up,
3203 I found that SYNC_INPUT has race conditions and would be a real
3204 pain to fix. Since it's an undocumented and deprecated
3205 configure-time option, now seems like a good time to remove it.
3206 Also see <http://bugs.gnu.org/11080#16>.
3207 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
3208 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.

3217 [!SYSTEM_MALLOC && !SYNC_INPUT]:
3218 Remove. All uses removed.
3219 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
3220 implementation, one that depends on whether the new macro
3221 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
3223 * atimer.c (run_timers, handle_alarm_signal):
3224 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)

3235 * eval.c (handling_signal): Remove. All uses removed.
3236 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
3237 All uses replaced with the SYNC_INPUT version.

3240 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3243 * font.c (Ffont_shape_gstring): Remove unused local.
3245 2012-09-16 Glenn Morris <rgm@gnu.org>
3247 * Makefile.in (clean): No longer run nextstep's clean.
3249 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
3251 (ns-app): Move here from ns.mk, and simplify.
3252 (clean): Simplify nextstep entry.
3253 * ns.mk: Remove file.
3255 2012-09-17 Kenichi Handa <handa@gnu.org>
3257 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
3258 not covert the last few charactes.
3260 2012-09-16 Kenichi Handa <handa@gnu.org>
3262 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
3263 here, but just check the validity of glyphs in the glyph-string.
3265 2012-09-16 Martin Rudalics <rudalics@gmx.at>
3267 * window.c (Fwindow_parameter, Fset_window_parameter):
3268 Accept any window as argument (Bug#12452).
3270 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
3272 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
3273 to ns_term_init to avoid memory leak.
3275 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
3276 explicit retain/release.
3277 (ns_term_init): Only allow one display. Initialize outerpool and
3280 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3282 Port _setjmp fix to POSIXish hosts as well as Microsoft.
3283 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
3284 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
3285 the Microsoft problem in a different way, by altering ../nt/config.nt.
3287 2012-09-15 Eli Zaretskii <eliz@gnu.org>
3302 * w16select.c: Remove inclusion of setjmp.h, as it is now included
3303 by lisp.h. This completes removal of setjmp.h inclusion
3304 erroneously announced in the previous commit. (Bug#12446)
3306 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
3309 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
3310 not defined as a macro. The latter happens on MS-Windows.
3313 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3315 Port better to POSIX hosts lacking _setjmp (Bug#12446).
3316 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
3317 Some instances of '#include <setjmp.h>' removed, if the
3318 only reason for the instance was because "lisp.h" was included.
3319 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
3320 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
3321 and _longjmp with the new symbols. Emacs already uses _setjmp if
3322 available, so this change affects only POSIXish hosts that have
3323 sigsetjmp but not _setjmp, such as some versions of Solaris and
3324 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
3325 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
3326 (png_load_body) [HAVE_PNG]:
3327 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
3328 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
3329 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
3330 since PNG requires jmp_buf. This is the only exception to the
3331 general rule that we now use sys_setjmp and sys_longjmp.
3332 This exception is OK since this code does not change the signal
3333 mask or longjmp out of a signal handler.
3335 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
3337 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3338 Include "syssignal.h", for 'main_thread'.
3340 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
3342 Avoid out-of-range marker position (Bug#12426).
3343 * insdel.c (replace_range, replace_range_2):
3344 Adjust markers before overlays, as suggested by comments.
3345 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
3346 Remove redundant check before calling offset_intervals.
3348 2012-09-14 Martin Rudalics <rudalics@gmx.at>
3350 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
3351 current buffer (Bug#12387).
3353 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
3355 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
3357 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3359 Use a more backwards-compatible timer format (Bug#12430).
3360 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
3361 vector element, not from the 4th, since PSECS is now at the end.
3362 (Fcurrent_idle_time): Doc fix.
3364 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
3366 Function to mark objects and remove killed buffers at once.
3367 * alloc.c (discard_killed_buffers): Rename to ...
3368 (mark_discard_killed buffers) ... new name. Add marking
3369 of remaining objects. Fix comment. Adjust users.
3370 (mark_object): Do not touch frame buffer lists here.
3371 * frame.c (delete_frame): Reset frame buffer lists here.
3373 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3375 Better workaround for GNOME bug when --enable-gcc-warnings.
3376 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
3377 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
3378 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
3380 Simplify SIGIO usage (Bug#12408).
3381 The code that dealt with SIGIO was crufty and confusing, e.g., it
3382 played tricks like "#undef SIGIO" but these tricks were not used
3383 consistently. Simplify mostly by not #undeffing standard symbols,
3384 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
3385 or not as we please) rather than "defined SIGIO" (standard symbol
3386 that we probably shouldn't #undef).
3387 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
3388 Modules that need it can include it.
3389 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
3390 * dispextern.h (ignore_sigio): New decl.
3391 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
3392 unconditionally, since it's now a no-op if !USABLE_SIGIO.
3393 * emacs.c (shut_down_emacs):
3394 * keyboard.c (kbd_buffer_store_event_hold):
3395 Use ignore_sigio rather than invoking 'signal' directly.
3396 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
3398 (FIONREAD, SIGIO): Do not #undef.
3399 (tty_read_avail_input): Use #error rather than a syntax error.
3400 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
3401 for I_PIPE, used by SETUP_SLAVE_PTY.
3402 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
3403 * sysdep.c (croak): Remove; no longer needed. This bit of
3404 temporary code, with Fred N. Fish's comment that it's temporary,
3405 has been in Emacs since at least 1992!
3406 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
3407 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
3408 * syssignal.h (croak): Remove decl.
3409 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
3410 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
3411 now that we're termios-only.
3412 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
3413 * term.c (dissociate_if_controlling_tty): Use #error rather than
3416 Work around GCC and GNOME bugs when --enable-gcc-warnings.
3417 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
3418 to work around GNOME bug 683906.
3419 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
3420 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
3421 This works around GCC bug 54561.
3423 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
3425 More fixes for 'volatile' and setjmp/longjmp.
3426 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
3427 * image.c (struct png_load_context) [HAVE_PNG]: New type.
3428 (png_load_body) [HAVE_PNG]:
3429 (jpeg_load_body) [HAVE_JPEG]:
3430 New function, with most of the old parent function's body.
3431 (png_load) [HAVE_PNG]:
3432 (jpeg_load) [HAVE_JPEG]:
3433 Invoke the new function, to avoid longjmp munging our locals.
3434 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
3435 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
3436 longjmp is passed 2, as the C standard doesn't guarantee this.
3437 Instead, store the failure code into mgr->failure_code.
3439 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
3441 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
3442 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
3443 (syms_of_keyboard): Remove support for unread-command-char.
3445 2012-09-12 Eli Zaretskii <eliz@gnu.org>
3447 * w32proc.c (sys_kill): If PID is our process ID and the signal is
3448 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
3449 violation. (Bug#12426)
3451 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
3453 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
3455 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
3457 * eval.c: Add `inhibit-debugger'.
3458 (Qinhibit_debugger): New symbol.
3459 (call_debugger): Bind it instead of Qdebug_on_error.
3460 (maybe_call_debugger): Test Vinhibit_debugger.
3461 (syms_of_eval): Define inhibit-debugger.
3462 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
3463 (syms_of_xdisp): Remove inhibit-debug-on-message.
3465 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
3467 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
3468 If a nonvolatile local variable is written before a _longjmp to
3469 the frame containing the variable, and is read after the _longjmp,
3470 the value read is indeterminate. Some local variables of type
3471 'struct handler' and 'struct catchtag' are used in this way, so
3472 mark each of their slots as volatile if the slot can be set before
3473 _longjmp and read afterwards.
3474 * lisp.h (struct handler): var and chosen_clause are now volatile.
3475 (struct catchtag): val, next, and pdlcount are now volatile.
3477 * bidi.c (bidi_push_it, bidi_pop_it):
3478 * fns.c (copy_hash_table):
3479 * image.c (define_image_type):
3480 * keyboard.c (kbd_buffer_store_event_hold):
3481 * process.c (Fprocess_send_eof):
3482 * xfaces.c (x_create_gc) [HAVE_NS]:
3483 * xgselect.c (xg_select):
3484 Prefer assignment to memcpy when either will do.
3486 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
3487 Use pointer-to-a-pointer to simplify and avoid a NILP check each
3488 time an item is removed. No need to mark this function 'inline';
3489 the compiler knows better than we do.
3491 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
3493 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
3494 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
3495 to change_frame_size (Bug#12388).
3496 (windowDidResize:): Pass YES to updateFrameSize.
3498 * nsterm.h: Add delay parameter to updateFrameSize.
3500 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
3502 Discard killed buffers from deleted window and frame objects.
3503 This reduces an amount of references to killed buffers and
3504 helps GC to reclaim them faster.
3505 * alloc.c (discard_killed_buffers): New function.
3506 (mark_object): Use it for deleted windows and frames.
3507 (mark_object): If symbol's value is set up for a killed buffer
3508 or deleted frame, restore its global binding.
3509 * data.c (swap_in_global_binding): Add GC notice.
3510 (swap_in_symval_forwarding): Use convenient set_blv_where.
3511 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
3512 * window.h: ... to here.
3514 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
3516 Convenient macro to check whether the buffer is live.
3517 * buffer.h (BUFFER_LIVE_P): New macro.
3518 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
3519 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
3521 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3523 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
3524 composition cases (Bug#12364).
3526 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
3527 overhang of succeeding glyphs overlapping box cursor.
3529 * w32term.c (x_draw_glyph_string): Likewise.
3531 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
3533 Simplify, document, and port floating-point (Bug#12381).
3534 The porting part of this patch fixes bugs on non-IEEE platforms
3535 with frexp, ldexp, logb.
3536 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
3538 * floatfns.c: Simplify discussion of functions that Emacs doesn't
3539 support, by removing commented-out code and briefly listing the
3540 C89 functions excluded. The commented-out stuff was confusing
3541 maintenance, e.g., we thought we needed cbrt but it was commented out.
3542 (logb): Remove decl; no longer needed.
3543 (isfinite): New macro, if not already supplied.
3544 (isnan): Don't replace any existing macro.
3545 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
3546 are present on all C89 platforms.
3547 (Ffrexp): Do not special-case zero, as frexp does the right thing
3549 (Flogb): Do not use logb, as it doesn't have the desired meaning
3550 on hosts that use non-base-2 floating point. Instead, stick with
3551 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
3552 frexp, to avoid getting an unspecified result.
3554 * xdisp.c (Qinhibit_debug_on_message): Now static.
3556 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
3558 * nsterm.m (ns_update_begin): Set clip path to whole view by using
3559 NSBezierPath (Bug#12131).
3561 2012-09-10 Chong Yidong <cyd@gnu.org>
3563 * fns.c (Fdelq, Fdelete): Doc fix.
3565 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
3567 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
3568 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
3570 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
3572 * lisp.h (make_lisp_ptr): New macro to replace XSET.
3573 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
3576 2012-09-09 Eli Zaretskii <eliz@gnu.org>
3578 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
3579 left fringe if the window has a left margin. This avoids leaving
3580 traces of the cursor because its leftmost pixel is not drawn over.
3582 * dispnew.c (update_window_line): When the left margin area of a
3583 screen line is updated, set the redraw_fringe_bitmaps_p flag of
3584 that screen line. (Bug#12277)
3586 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
3588 Assume C89 or later for math functions (Bug#12381).
3589 This simplifies the code, and makes it a bit smaller and faster,
3590 and (most important) makes it easier to clean up signal handling
3591 since we can stop worring about floating-point exceptions in
3592 library code. That was a problem before C89, but the problem
3593 went away many years ago on all practical Emacs targets.
3594 * data.c, image.c, lread.c, print.c:
3595 Don't include <math.h>; no longer needed.
3596 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
3597 might be autoconfigured, as that never happens.
3599 * doprnt.c (DBL_MAX_10_EXP):
3600 * print.c (DBL_DIG):
3601 Remove. C89 or later always defines these.
3602 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
3603 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
3604 (arith_error, domain_error, domain_error2):
3605 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
3606 no longer needed -- we simply return what C returns. All uses removed.
3607 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
3609 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
3610 Remove. All uses expanded, as these macros are no longer used
3611 more than once and are now more trouble than they're worth.
3612 (Ftan): Use tan, not sin / cos.
3613 (Flogb): Assume C89 frexp.
3614 (fmod_float): Assume C89 fmod.
3615 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
3616 (init_floatfns): Remove. All uses removed.
3618 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3620 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
3621 compositeToPoint for OSX < 10.6 (Bug#12390).
3623 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
3625 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
3626 This produces more-accurate results.
3628 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3630 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
3631 changes (Bug#12088).
3633 2012-09-08 Chong Yidong <cyd@gnu.org>
3635 * syntax.c (Fstring_to_syntax): Doc fix.
3637 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3639 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
3640 in the internal border.
3641 (x_set_window_size): Remove static variables and their usage.
3642 (ns_redraw_scroll_bars): Fix NSTRACE arg.
3643 (ns_after_update_window_line, ns_draw_fringe_bitmap):
3644 Remove fringe/internal border adjustment (Bug#11052).
3645 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
3646 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
3647 (ns_fix_rect_ibw): Remove.
3648 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
3649 (ns_dumpglyphs_box_or_relief): Ditto.
3650 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
3652 (ns_dumpglyphs_image): Ditto.
3653 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
3655 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
3656 their usage. Add fringe_extended_p and its use as in other terms.
3657 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
3658 scroll bar was removed.
3659 (updateFrameSize): New function.
3660 (windowDidResize): Move code to updateFrameSize and call it.
3662 * nsterm.h (EmacsView): Add updateFrameSize.
3664 2012-09-07 Chong Yidong <cyd@gnu.org>
3666 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
3668 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
3670 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
3672 More signal-handler cleanup (Bug#12327).
3673 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
3674 Problem introduced when merging patches. Noted by Eli Zaretskii in
3675 <http://bugs.gnu.org/12327#67>.
3676 * floatfns.c: Comment fix.
3677 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
3678 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
3679 and anyway the declaration is harmless even if SIGDANGER is not defined.
3680 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
3681 defined BROKEN_FIONREAD). systty.h formerly did this, but other
3682 source files not surprisingly expected syssignal.h to define, or
3683 not define, SIGIO, and it's cleaner to do it that way, for consistency.
3684 Include <sys/ioctl.h>, for FIONREAD.
3685 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
3686 This eliminates a problem whereby other files mysteriously had
3687 to include "syssignal.h" before including "systty.h" if they
3688 wanted to use "#ifdef SIGIO".
3690 2012-09-07 Eli Zaretskii <eliz@gnu.org>
3692 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
3694 * w32.c (sigemptyset): Empty the set.
3695 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
3697 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
3699 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
3701 * alloc.c (mark_buffer): Revert unsafe marking optimization.
3702 (mark_object): Likewise for frame objects.
3704 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
3706 * syssignal.h (handle_on_main_thread): Always declare,
3707 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
3708 This ports to platforms without HAVE_PTHREAD.
3710 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
3712 Signal-handler cleanup (Bug#12327).
3713 Emacs's signal handlers were written in the old 4.2BSD style with
3714 sigblock and sigmask and so forth, and this led to some
3715 inefficiencies and confusion. Rewrite these to use
3716 pthread_sigmask etc. without copying signal sets around. Also,
3717 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
3718 'signal', and instead use functions that do not attempt to take
3719 over the system name space. This patch causes Emacs's text
3720 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
3721 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
3722 Do not include <signal.h> or "syssignal.h", as these
3723 modules do not use signals.
3724 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
3725 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
3726 Do not include <signal.h>, as "syssignal.h" does that for us now.
3727 * atimer.c (sigmask_atimers): New function.
3728 (block_atimers, unblock_atimers): New functions,
3729 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
3731 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
3732 no longer needed here.
3733 * emacs.c (main): Inspect existing signal handler with sigaction,
3734 so that there's no need to block and unblock SIGHUP.
3735 * sysdep.c (struct save_signal): New member 'action', replacing
3736 old member 'handler'.
3737 (save_signal_handlers, restore_signal_handlers):
3738 Use sigaction instead of 'signal' to save and restore.
3739 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
3740 New function. All users of 'signal' modified to use set_sighandler
3741 if they're writeonly, and to use sys_signal if they're read+write.
3742 (emacs_sigaction_init, forwarded_signal): New functions.
3743 (sys_signal): Remove. All uses replaced by calls to sigaction
3744 and emacs_sigaction_init, or by direct calls to 'signal'.
3745 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
3746 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
3747 all uses replaced by pthread_sigmask etc. calls.
3748 * syssignal.h: Include <signal.h>.
3749 (emacs_sigaction_init, forwarded_signal): New decls.
3750 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
3751 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
3752 (sigmask, sys_sigmask): Remove; no longer needed.
3753 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
3754 (sigblock, sigunblock, sigfree):
3755 (sigsetmask) [!defined sigsetmask]:
3756 Remove. All uses replaced by pthread_sigmask.
3757 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
3758 no longer need to be replaced, and its typical old uses
3759 are now done via emacs_sigaction_init and sigaction.
3760 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
3761 (sys_sigdel): Remove; unused.
3762 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
3764 2012-09-06 Eli Zaretskii <eliz@gnu.org>
3766 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
3767 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
3769 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
3771 Explicitly mark buffer_defaults and buffer_local_symbols.
3772 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
3773 mark_local_symbols here.
3774 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
3775 since special buffers aren't marked here any more.
3776 (allocate_buffer): Chain new buffer with all_buffers here...
3777 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
3779 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
3780 (syms_of_buffer): Remove staticpro of the above.
3781 (init_buffer_once): Set names for buffer_defaults and
3782 buffer_local_symbols.
3784 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
3786 Use bool for booleans in font-related modules.
3787 * font.c (font_intern_prop, font_style_to_value)
3788 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
3789 (generate_otf_features, font_check_otf_features, font_check_otf)
3790 (font_match_p, font_list_entities, font_at):
3791 * fontset.c (fontset_id_valid_p, reorder_font_vector
3792 (fontset_find_font, Fset_fontset_font)
3793 (face_suitable_for_char_p) [0]:
3794 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
3795 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
3796 (m17n_flt_initialized, ftfont_shape_by_flt):
3797 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
3798 * nsfont.m (nsfont_draw):
3799 * w32font.c (w32font_draw):
3800 * w32term.c (x_draw_glyphless_glyph_string_foreground):
3801 Use bool for booleans.
3802 * font.h: Adjust to above API changes.
3803 (struct font, struct font_driver, struct font_driver_list):
3804 Use bool for booleans.
3805 (struct font): Remove useless member encoding_type.
3807 * fontset.c, xftfont.c: Omit unnecessary static decls.
3809 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
3811 * alloc.c (mark_object): Revert window marking code
3812 since it's unsafe for the Fset_window_configuration.
3814 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
3816 Fix race conditions with signal handlers and errno (Bug#12327).
3817 Be more systematic about preserving errno whenever a signal
3818 handler returns, even if it's not in the main thread. Do this by
3819 renaming signal handlers to distinguish between signal delivery
3820 and signal handling. All uses changed.
3821 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
3822 * data.c (deliver_arith_signal): Rename from arith_error.
3823 * dispnew.c (deliver_window_change_signal): Rename from
3824 window_change_signal.
3825 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
3826 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
3827 * keyboard.c (deliver_input_available_signal): Rename from
3828 input_available_signal.
3829 (deliver_user_signal): Rename from handle_user_signal.
3830 (deliver_interrupt_signal): Rename from interrupt_signal.
3831 * process.c (deliver_pipe_signal): Rename from send_process_trap.
3832 (deliver_child_signal): Rename from sigchld_handler.
3833 * atimer.c (handle_alarm_signal):
3834 * data.c (handle_arith_signal):
3835 * dispnew.c (handle_window_change_signal):
3836 * emacs.c (handle_fatal_signal, handle_danger_signal):
3837 * keyboard.c (handle_input_available_signal):
3838 * keyboard.c (handle_user_signal, handle_interrupt_signal):
3839 * process.c (handle_pipe_signal, handle_child_signal):
3840 New functions, with the actual signal-handling code taken from the
3841 original respective signal handlers, sans the sporadic attempts to
3842 preserve errno, since that's now done by handle_on_main_thread.
3843 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
3844 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
3845 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3847 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3848 Move initialization of main_thread to sysdep.c's init_signals.
3849 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
3850 our usage, and simplifies the mainline code.
3851 (record_child_status_change): New static function, as a helper
3852 for handle_child_signal, and with most of the old child handler's
3854 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
3855 (handle_child_signal): Use the above.
3856 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3857 Moved here from emacs.c.
3858 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
3859 code moved here from emacs.c's main function.
3860 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
3861 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
3862 This lets callers save and restore errno properly.
3864 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3866 Remove redundant or unused things here and there.
3867 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
3868 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
3869 * editfns.c (Fcompare_buffer_substrings): Likewise.
3870 * frame.h (struct terminal, struct font_driver_list):
3871 Remove redundant declarations.
3872 * window.h (Qleft, Qright): Likewise.
3874 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3876 Do not mark objects from deleted buffers, windows and frames.
3877 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
3878 (mark_object): Likewise for windows and frames.
3880 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3882 * alloc.c (valid_lisp_object_p): Treat killed buffers,
3883 buffer_defaults and buffer_local_symbols as valid objects.
3884 Return special value to denote them.
3886 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
3888 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
3889 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
3890 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
3891 (file_name_absolute_p, Fsubstitute_in_file_name):
3892 (check_executable, check_writable, Ffile_accessible_directory_p)
3893 (Fset_file_selinux_context, Fdefault_file_modes)
3894 (Finsert_file_contents, choose_write_coding_system)
3895 (Fwrite_region, build_annotations, a_write, e_write)
3897 * filelock.c (boot_time_initialized, get_boot_time)
3898 (get_boot_time_1, lock_file_1, within_one_second):
3899 * floatfns.c (in_float):
3900 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
3901 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
3902 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
3903 * lisp.h (struct Lisp_Hash_Table.cmpfn):
3904 * window.c (compare_window_configurations):
3905 Use bool for booleans.
3906 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
3907 (Fdefault_file_modes): Now mode_t, not int, for modes.
3908 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
3909 (internal_delete_file): Now returns void, not a (boolean) int,
3910 since nobody was looking at the return value.
3911 * lisp.h, window.h: Adjust to above API changes.
3913 * xdisp.c (set_message): Simplify and reindent last change.
3915 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
3917 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
3919 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
3921 * eval.c (call_debugger): Make the function non-static so that we
3922 can call it from set_message.
3924 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
3925 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
3927 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3929 Give more-useful info on a fatal error (Bug#12328).
3930 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
3931 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
3932 of doing the work ourselves.
3933 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
3934 do most of the work.
3935 (fatal_error_backtrace): New function, taken from the guts
3936 of the old fatal_error_signal, but with a new option to output
3938 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
3939 info about the signal than just its number.
3940 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
3941 * sysdep.c: Include <execinfo.h>
3942 (emacs_backtrace): New function, taken partly from the previous
3943 code of the 'die' function.
3944 (emacs_abort): Call fatal_error_backtrace rather than abort.
3946 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
3948 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
3949 eager (load-time) macro-expansion.
3950 * lisp.mk (lisp): Add macroexp.
3952 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3954 Simplify redefinition of 'abort' (Bug#12316).
3955 Do not try to redefine the 'abort' function. Instead, redo
3956 the code so that it calls 'emacs_abort' rather than 'abort'.
3957 This removes the need for the NO_ABORT configure-time macro
3958 and makes it easier to change the abort code to do a backtrace.
3959 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
3960 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
3961 Remove; sysdep.c's emacs_abort now takes its place.
3962 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
3963 'abort' changed to use 'emacs_abort'.
3964 * msdos.c (dos_abort) [defined abort]: Remove; not used.
3965 (abort) [!defined abort]: Rename to ...
3966 (emacs_abort): ... new name.
3967 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
3968 the place of the old 'abort' in emacs.c.
3969 * w32.c, w32fns.c (abort): Do not #undef.
3970 * w32.c (emacs_abort): Rename from w32_abort.
3972 2012-09-04 Eli Zaretskii <eliz@gnu.org>
3974 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
3975 offsets[j].dv, since the y axis of the screen coordinates points
3976 down, while the y axis of the font definition coordinates points
3977 up. This fixes display of Arabic diacritics such as KASRA and
3978 KASRATAN. (Bug#11860)
3980 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3982 Be more systematic about _setjmp vs setjmp.
3983 * alloc.c (test_setjmp, mark_stack):
3984 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
3985 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
3986 (png_load, my_error_exit, jpeg_load):
3987 * process.c (send_process_trap, send_process):
3988 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
3989 The underscored versions are up to 30x faster on some hosts.
3990 Formerly, the code used setjmp+longjmp sometimes and
3991 _setjmp+_longjmp at other times, with no particular reason to
3992 prefer setjmp+longjmp.
3994 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
3996 Fix minor problem found by static checking.
3997 * buffer.c (Fdelete_all_overlays): Return nil.
3999 2012-09-03 Martin Rudalics <rudalics@gmx.at>
4001 * buffer.c (Fdelete_all_overlays): New function.
4003 2012-09-03 Chong Yidong <cyd@gnu.org>
4005 * gtkutil.c: Add extern decl for Qxft.
4007 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
4009 * emacs.c, eval.c: Use bool for boolean.
4010 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
4011 (malloc_using_checking) [DOUG_LEA_MALLOC]:
4012 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
4013 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
4014 (main, decode_env_path, Fdaemon_initialized):
4015 * eval.c (call_debugger, Finteractive_p, interactive_p):
4016 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
4017 (maybe_call_debugger, Fbacktrace):
4018 * process.c (read_process_output, exec_sentinel):
4019 Use bool for booleans.
4020 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
4021 All callers changed.
4022 * eval.c (interactive_p): Omit always-true boolean argument
4023 EXCLUDE_SUBRS_P. All callers changed.
4024 * dispextern.h, lisp.h: Reflect above API changes.
4025 * firstfile.c (dummy): Use the address of 'main', whose signature
4026 won't change, instead of the address of 'initialize', whose
4027 signature just changed from int to bool.
4028 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
4029 * msdos.c (fatal_error_in_progress): ... from here.
4030 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
4032 (redisplay_internal, unwind_redisplay): Simply clear
4033 REDISPLAYING_P when unwinding, instead of saving its previous,
4034 always-false value and then restoring it.
4036 Clean up some extern decls.
4037 Mostly, this hoists extern decls out of .c files and into .h files.
4038 That way, we're more likely to catch errors if the interfaces change.
4039 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
4040 declare xg_mark_data.
4041 * dispextern.h (x_frame_parm_handlers):
4043 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
4044 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
4045 (Qultra_bold, Qoblique, Qitalic):
4046 Move extern decl here from .c file.
4047 * alloc.c (xg_mark_data) [USE_GTK]:
4049 * eval.c (Qlexical_binding):
4050 * fns.c (time) [!HAVE_UNISTD_H]:
4051 * gtkutil.c (Qxft, Qnormal, Qextra_light, Qlight, Qsemi_light)
4052 (Qsemi_bold, Qbold, Qextra_bold, Qultra_bold, Qoblique, Qitalic):
4053 * image.c (Vlibrary_cache, QCloaded_from) [HAVE_NTGUI]:
4054 * lread.c (Qinternal_interpreter_environment):
4055 * minibuf.c (Qbuffer):
4056 * process.c (QCfamily, QCfilter):
4057 * widget.c (free_frame_faces):
4058 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
4059 * xfont.c (x_clear_errors):
4060 * xterm.c (x_frame_parm_handlers):
4061 Remove now-redundant extern decls.
4062 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
4063 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
4065 * xfaces.c: Remove unnecessary static decls.
4066 * xterm.c (updating_frame): Remove decl of nonexistent object.
4068 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
4069 when building globals.h, as the objects that are not built on
4070 this host are not needed to compile C files on this host.
4072 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
4074 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
4076 * frame.h: Add missing prototype for x_wm_set_size_hint.
4078 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
4080 * doc.c, editfns.c, insdel.c, intervals.c: Use bool for boolean.
4081 * doc.c (read_bytecode_char, get_doc_string, reread_doc_file)
4082 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
4083 (Fsubstitute_command_keys):

4126 offset adjustment values separately for each cluster. (Bug#11860)
4128 * image.c: Restore mistakenly removed inclusion of w32.h. Without
4129 it, GCC doesn't see prototypes of w32_delayed_load, and complains
4130 about implicit conversions from integer to pointer.

4188 window system declarations.
4190 * frame.h: Move common functions here: set_frame_menubar,
4191 x_set_window_size, x_sync, x_get_focus_frame,

4224 * term.c (mark_ttys): Remove.
4225 (init_tty): Safely initialize 'top_frame' slot with Qnil.

4249 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
4250 for GCC 4.7.1 x86-64.
4252 2012-08-30 Glenn Morris <rgm@gnu.org>
4254 * lread.c (init_lread): For out-of-tree builds, only add the
4255 source directory's site-lisp dir to the load-path if it exists,
4256 consistent with in-tree builds. (Bug#12302)
4258 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

4492 It was meant to be temporary and it often doesn't work,
4493 because when IDX has side effects the behavior of IDX==IDX
4494 is undefined. See Stefan Monnier in
4495 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.

4506 as that's faster and simpler than static storage. Don't bother
4507 with the g_main_context_query overhead if g_main_context_pending
4508 says no events are pending.
4509 (gfds, gfds_size): Remove these static vars.
4510 (xgselect_initialize): Remove; no longer needed.
4511 All uses and decls removed.

4537 * callint.c (check_mark, Fcall_interactively):
4538 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
4539 (getenv_internal, sync_process_alive, call_process_exited):
4540 * lisp.h (USE_SAFE_ALLOCA):
4541 Use bool for booleans, instead of int.
4542 * lisp.h, process.h: Adjust prototypes to match above changes.
4543 * callint.c (Fcall_interactively): Don't assume the mark's
4544 offset fits in 'int'.
4546 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
4548 * buffer.c, buffer.h: Use bool for boolean.
4549 * buffer.c (reset_buffer_local_variables)
4550 (buffer_lisp_local_variables, Fset_buffer_modified_p)
4551 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
4552 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
4553 (overlay_touches_p, overlay_strings, Foverlay_put)
4554 (report_overlay_modification, call_overlay_mod_hooks):
4555 (mmap_enlarge, mmap_set_vars):
4556 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
4557 Use bool for booleans, instead of int.
4558 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
4559 since the 1-or-0 return value is always ignored anyway.
4560 (mmap_initialized_p):
4561 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
4562 * buffer.h, lisp.h: Adjust prototypes to match above changes.
4564 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
4566 * bidi.c: Use bool for boolean.
4567 This is a bit more readable, and makes the text segment of bidi.o
4568 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
4569 Presumably it's faster too.
4570 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
4572 (bidi_cache_find_level_change, bidi_cache_iterator_state)
4573 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
4574 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
4575 (bidi_explicit_dir_char, bidi_level_of_next_char)
4576 (bidi_find_other_level_edge, bidi_move_to_visually_next):
4577 Use bool for booleans, instead of int.
4578 * dispextern.h (bidi_init_it, bidi_paragraph_init)
4579 (bidi_unshelve_cache): Adjust decls to match code.
4581 2012-08-23 Martin Rudalics <rudalics@gmx.at>
4583 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
4586 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
4588 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
4589 * atimer.h: Include <stdbool.h>.
4591 2012-08-22 Dan Nicolaescu <dann@gnu.org>
4593 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
4594 compile time tests instead of run time tests on systems that do
4596 (FRAME_MAC_P): Remove leftover from deleted code.
4597 * frame.c (syms_of_frame): Remove leftover from deleted code.
4599 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
4601 * nsterm.m (insertText:): Don't clear modifiers if code is space.
4603 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
4605 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
4606 Otherwise, the compiler complains about (A?B:C) where B is void
4607 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
4608 (fontset_add): Return void, for FONTSET_ADD.
4610 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4612 * alloc.c: Use bool for booleans.
4613 (gc_in_progress, abort_on_gc)
4614 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
4615 (dont_register_blocks) [GC_MALLOC_CHECK]:
4616 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
4617 (check_string_bytes, make_specified_string, memory_full)
4618 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
4619 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
4620 (mark_stack, valid_pointer_p, make_pure_string)
4621 (Fgarbage_collect, survives_gc_p, gc_sweep):
4622 Use bool for booleans, instead of int.
4623 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
4624 Remove unused local.
4625 * alloc.c (PURE_POINTER_P):
4626 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
4627 * editfns.c (Fformat):
4628 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
4630 * fns.c (sweep_weak_table):
4631 * lisp.h (suppress_checking, push_message, survives_gc_p)
4632 (make_pure_string, gc_in_progress, abort_on_gc):
4633 * lread.c (readchar, read1):
4634 * print.c (Fprin1_to_string):
4635 * xdisp.c (push_message):
4636 Use bool for booleans affected directly or indirectly by
4639 Make recently-introduced setters macros.
4640 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
4641 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
4642 (set_fontset_default, set_fontset_fallback): Rename from their
4643 upper-case counterparts, and make them functions rather than macros.
4644 This is more consistent with the other recently-introduced setters.
4645 These don't need to be inline, since they're local.
4647 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
4649 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
4650 the loop (Bug#12247).
4652 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4654 * lisp.h (vcopy): Use memcpy rather than our own loop.
4655 This fixes a performance regression introduced by the recent
4656 addition of vcopy. This means 'vcopy' will need to be modified
4657 for a copying collector, but that's OK. Also, tighten the
4658 checking in the assertion.
4660 2012-08-21 Eli Zaretskii <eliz@gnu.org>
4662 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
4663 components for RTL text (Bug#11860). Adjust X-OFFSET of each
4664 non-base glyph for the width of the base character, according to
4665 what x_draw_composite_glyph_string_foreground expects.
4666 Generate WADJUST value according to composition_gstring_width's
4667 expectations, to produce correct width of the composed character.
4668 Reverse the sign of the DU offset produced by ScriptPlace.
4670 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4672 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
4674 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
4676 Avoid direct writes to contents member of struct Lisp_Vector.
4677 * lisp.h (vcopy): New function to copy data into vector.
4678 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
4679 * fns.c (Ffillarray): Use ASET.
4680 * keyboard.c (timer_check_2): Use AREF and ASET.
4681 (append_tool_bar_item, Frecent_keys): Use vcopy.
4682 * lread.c (read_vector): Use ASET.
4683 * msdos.c (Frecent_doskeys): Use vcopy.
4684 * xface.c (Finternal_copy_lisp_face): Use vcopy.
4685 (Finternal_merge_in_global_face): Use ASET and vcopy.

4691 the position of its buffer's point.
4692 (Fset_window_point): For the selected window always go in its
4693 buffer to the specified position.
4695 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
4697 Setter macros for fontsets.
4698 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
4699 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
4700 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
4703 2012-08-20 Glenn Morris <rgm@gnu.org>
4705 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
4706 Don't assume that `ln -f' works.
4708 2012-08-20 Eli Zaretskii <eliz@gnu.org>
4710 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
4711 and later about non-assignments with no effect. See discussion at
4712 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
4715 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
4717 Inline setter functions for Lisp_Objects slots of struct specbinding.
4718 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
4721 2012-08-20 Martin Rudalics <rudalics@gmx.at>
4723 * window.c (select_window): Always make selected window's buffer
4726 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
4728 Use AREF and ASET for docstrings of category tables.
4729 * category.h (CATEGORY_DOCSTRING): Use AREF.
4730 (SET_CATEGORY_DOCSTRING): Use ASET.
4731 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
4733 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
4735 Inline setter functions for hash table members.
4736 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
4737 (set_hash_hash, set_hash_index): Rename with _slot suffix.
4738 (set_hash_key_and_value, set_hash_index, set_hash_next)
4739 (set_hash_hash): New functions.
4740 * charset.c, fns.c: Adjust users.
4742 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
4744 Inline getter and setter functions for per-buffer values.
4745 * buffer.h (per_buffer_default, set_per_buffer_default)
4746 (per_buffer_value, set_per_buffer_value): New functions.
4747 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
4748 * buffer.c, data.c: Adjust users.
4750 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
4752 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
4754 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
4756 Rely on <config.h> + <unistd.h> to declare 'environ',
4757 as gnulib does this if the system doesn't.
4758 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
4759 Remove declaration. MS-Windows declares it on stdlib.h which is
4760 included by conf_post.h.
4761 * emacs.c (environ) [DOUG_LEA_MALLOC]:
4762 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
4763 * vm-limit.c: Include <unistd.h>, for 'environ'.
4765 * unexaix.c, unexcoff.c: Include "mem-limits.h".
4766 (start_of_data): Remove decl; mem-limits.h provides it.
4768 * xdisp.c (handle_invisible_prop): Make it a bit faster
4769 and avoid a gcc -Wmaybe-uninitialized diagnostic.
4771 2012-08-19 Chong Yidong <cyd@gnu.org>
4773 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
4776 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
4778 * .gdbinit: Use call instead of set when calling a function in the
4781 * data.c (set_internal): Don't use set_blv_found.
4782 (Fkill_local_variable): Likewise.
4784 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
4786 * nsfont.m (ns_ascii_average_width): Ensure the string
4787 ascii_printable is initialized with a null-terminated character
4788 array. Otherwise, it can contain undesired extra characters.
4790 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
4792 port new setting code to Sun C 5.8 2005/10/13
4793 * chartab.c, lisp.h (char_table_set, char_table_set_range):
4794 Return void, not Lisp_Object. Otherwise, the compiler
4795 complains about (A?B:C) where B is void and C is Lisp_Object
4796 when compiling CHAR_TABLE_SET, due to the recent change to
4797 the API of sub_char_table_set_contents.
4799 2012-08-18 Chong Yidong <cyd@gnu.org>
4801 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
4802 for the string case (Bug#3874).
4804 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
4806 * buffer.h (BSET): Remove (Bug#12215).

4885 are compiled into code.
4886 (tset_param_alist): New setter function.
4888 2012-08-17 Paul Eggert <eggert@cs.ucla.edu>
4890 * keyboard.h (KSET): Remove (Bug#12215).

4923 A few more naming-convention fixes for getters and setters.
4924 * buffer.c (set_buffer_overlays_before): Move here from buffer.h,
4925 and rename from buffer_overlays_set_before.
4926 (set_buffer_overlays_after): Move here from buffer.h, and rename
4927 from buffer_overlays_set_after.
4928 * buffer.h (buffer_intervals): Rename from buffer_get_intervals.

5629 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
5630 * w32.c (init_environment): Change the default values of many
5631 environment variables in dflt_envvars[] to NULL, to avoid pushing
5632 them into environment when they were not already defined.
5633 Remove the code that deletes site-lisp subdirectories from the default
5634 value of EMACSLOADPATH, as it is no longer needed.
5635 (check_windows_init_file): Now external, not static.
5636 Use Vload_path as is, without adding anything, as this function is now
5637 called when Vload_path is already set up.
5639 * w32.h (check_windows_init_file): Add prototype.
5641 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

5648 installation tree, as appropriate.
5650 * callproc.c (init_callproc_1): Call decode_env_path instead of
5651 doing its equivalent by hand.

5669 Remove unnecessary casts involving pointers.
5670 These casts are no longer needed now that we assume C89 or later,

5684 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
5685 Remove unnecessary pointer casts.
5686 * alloc.c (record_xmalloc): New function.
5687 * lisp.h (record_xmalloc): New decl.
5688 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
5689 more like a function. This is because the pointer cast is not
5690 needed. All uses changed.
5691 * print.c (print_string, print_error_message): Avoid length recalc.
5693 Improve fix for macroexp crash with debugging (Bug#12118).
5694 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
5695 ARRAY_MARK_FLAG when checking subscripts, because ASET is
5696 not supposed to be invoked from the garbage collector.

5698 (gc_aset): New function, which is like ASET but can be
5699 used in the garbage collector.

5728 with addition of handling of symlinks and support for 'lstat'.
5729 If possible, get file's attributes and security information by
5730 handle, not by name. Produce S_IFLNK bit for symlinks, when
5731 called from 'lstat'.
5732 (stat, lstat): New functions, call 'stat_worker'.
5733 (symlink, readlink, careadlinkat): Rewritten to create and resolve
5734 symlinks when the underlying filesystem supports them.
5736 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
5738 Fix macroexp crash on Windows with debugging (Bug#12118).
5739 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
5740 checking subscripts; problem introduced with the recent
5741 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
5742 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
5743 since it's used in non-static inline functions now.
5745 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
5746 Don't assume buffer size fits in 'int'. Remove unused local.

5766 * composite.c (COMPOSITE_INLINE):
5767 * dispnew.c (DISPEXTERN_INLINE):
5768 * sysdep.c (SYSTIME_INLINE):
5769 Define to EXTERN_INLINE, so that the corresponding functions
5770 are compiled into code.
5771 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
5772 (INLINE_HEADER_END): New macros.
5773 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

5793 hard-coding the path separator.
5795 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
5797 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
5798 This how ASET and AREF are supposed to work, and makes
5799 it easier to think about future improvements. See
5800 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
5801 * charset.h (set_charset_attr): New function.

6293 the fix for 12036 would have avoided some of the problems noted in

6297 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
6298 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
6299 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
6300 Remove; now done in lisp.h.
6301 * lisp.h (PUBLISH_TO_GDB): New macro.

6303 (DATA_SEG_BITS): Use it.
6304 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
6305 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
6306 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
6307 not be usable in #if. This simplifies things.
6309 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
6311 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

6316 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
6317 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
6318 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
6319 Adjust to changes in lisp.h and emacs.c, by using
6320 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
6321 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
6322 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
6323 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
6324 instead of gdb_valbits.
6325 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
6326 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
6327 instead of gdb_array_mark_flag.
6328 (xboolvector): Get size from $->size, not $->header.size.
6329 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
6330 (xreload, hook-run, hookpost-run): Remove.
6331 * emacs.c: Include <verify.h>.
6332 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
6333 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
6335 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
6336 (gdb_USE_LSB_TAG): New enum constants.
6337 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
6338 Also define these as enum constants, so they're visible to GDB.
6339 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
6340 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
6341 as constants, so they're visible to GDB.

6343 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
6344 Now enum constants, not macros, so they're visible to GDB.
6345 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
6346 more convenient now. All uses changed.
6347 (VALMASK) [USE_LSB_TAG]: Also define in this case.

6360 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
6362 Use typedef for EMACS_INT, EMACS_UINT.
6363 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
6364 than macros. This simplifies debugging in the usual case, since
6365 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
6366 and it allows expressions involving EMACS_INT casts.
6367 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
6369 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

6384 by Christoph Scholtes again. (Bug#12007).
6385 (init_buffer_once): Initialize indirection counters of
6386 buffer_defaults and buffer_local_symbols (for sanity and safety).
6388 2012-07-24 Eli Zaretskii <eliz@gnu.org>

6419 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
6421 Swap buffer text indirection counters in Fbuffer_swap_text.
6422 * buffer.c (Fbuffer_swap_text): Swap indirections too.
6423 This avoids crash reported by Christoph Scholtes at
6424 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
6426 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
6428 * nsmenu.m (Popdown_data): New struct.

6451 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
6453 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
6454 as it's limited by the amount of memory, not by INT_MAX.
6456 2012-07-21 Eli Zaretskii <eliz@gnu.org>
6458 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'

6609 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
6611 * eval.c (Fdefvar): Don't check constants since we only set the var if
6612 it's not yet defined anyway (bug#11904).
6614 * lisp.h (last_undo_boundary): Declare new var.
6615 * keyboard.c (command_loop_1): Set it.
6616 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
6617 were auto-added by the command loop (bug#11774).

7205 (add_emacs_time, sub_emacs_time): New functions.
7206 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

7232 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
7233 * nsterm.m (ns_term_init):
7234 Avoid the need for strncpy, by using build_string or
7235 make_unibyte_string directly. Use dtoastr, not snprintf.
7236 * process.c (Fmake_network_process): Diagnose service names that
7237 are too long, rather than silently truncating them or creating
7238 non-null-terminated names.
7239 (Fnetwork_interface_info): Likewise, for interface names.
7240 * sysdep.c (system_process_attributes) [GNU_LINUX]:
7241 Prefer sprintf to strncat.
7242 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:

7254 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
7255 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR

7268 Optimize pure C strings initialization.
7269 * lisp.h (make_pure_string): Fix prototype.
7270 (build_pure_c_string): New function, defined as static inline. This
7271 provides a better opportunity to optimize away calls to strlen when
7272 the function is called with compile-time constant argument.
7273 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
7274 argument, adjust users accordingly. Use build_pure_c_string where
7276 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
7277 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
7278 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
7280 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
7282 Avoid calls to strlen in miscellaneous functions.
7283 * buffer.c (init_buffer): Use precalculated len, adjust if needed.

7305 * s/gnu.h (DATA_START): Move definitions to configure.
7307 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
7308 We include usg5-4-common.h, which defines them both.
7310 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
7311 O_RDONLY already includes it).
7313 Stop ns builds setting the EMACSLOADPATH environment variable.
7314 * nsterm.m (ns_load_path): Rename from ns_init_paths.
7315 Now it does not set EMACSLOADPATH, just returns the load-path string.
7316 * nsterm.h: Update accordingly.
7317 * lread.c [HAVE_NS]: Include nsterm.h.
7318 (init_lread) [HAVE_NS]: Use ns_load_path.

7321 2012-07-09 Glenn Morris <rgm@gnu.org>
7323 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
7324 since the included bsd-common.h does so.
7326 Stop ns builds setting the EMACSPATH environment variable.
7327 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
7328 (ns_init_paths): Do not set EMACSPATH.
7329 * nsterm.h (ns_exec_path): Add it.
7330 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
7333 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
7335 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
7337 * process.c (wait_reading_process_output): 'waitchannels' was unset
7338 when read_kbd || !NILP (wait_for_cell); fix this.
7340 Add GCC-style 'const' attribute to functions that can use it.
7341 * character.h (char_resolve_modifier_mask):
7342 * keyboard.h (make_ctrl_char):
7343 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

7352 Add decls with ATTRIBUTE_CONST.
7354 Minor improvements to make_formatted_string.
7355 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
7356 where int is good enough, as vsprintf returns an int.
7357 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
7359 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7361 Use make_formatted_string to avoid double length calculation.
7362 * lisp.h (make_formatted_string): New prototype.

7386 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7388 Move marker debugging code under MARKER_DEBUG.
7389 * marker.c (MARKER_DEBUG): Move marker debugging code under
7390 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
7391 for bootstrap with --enable-checking (~3x slowdown reported
7392 by Juanma Barranquero <lekktu@gmail.com>).
7393 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
7395 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
7397 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
7398 See <http://bugs.gnu.org/11825#29>.
7400 2012-07-08 Eli Zaretskii <eliz@gnu.org>
7402 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
7403 has no font, use the frame's font. (Bug#11813)
7404 (display_line): Add commentary about displaying truncation glyphs
7406 (produce_special_glyphs): Move here from term.c.
7408 * term.c (produce_special_glyphs): Move to xdisp.c.
7410 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
7413 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
7415 * xdisp.c (display_line): Avoid warning about implicit declaration
7418 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
7420 * lisp.h: Remove empty conditional.
7422 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
7424 * lread.c (load_path_check): Now static.
7426 Fix some minor --with-ns problems found by static checking.
7427 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
7428 (x_set_font) [!HAVE_X_WINDOWS]:
7429 * image.c (xpm_load_image) [HAVE_NS]:
7430 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
7431 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
7432 Remove unused local.
7433 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
7434 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
7435 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
7436 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
7437 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
7438 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
7439 Fix pointer signedness problem.
7440 * xfaces.c (FRAME_X_FONT_TABLE):
7441 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
7443 2012-07-07 Glenn Morris <rgm@gnu.org>
7445 * lread.c (load_path_check): New function, split from init_lread.
7446 (init_lread): Reorganize. Motivation:
7447 If EMACSLOADPATH is set, check/warn about that rather than the
7448 defaults, which we are not going to use. Hence we can remove
7449 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
7450 Don't warn if site-lisp directories are missing.
7451 If not installed, start from a blank load-path, since
7452 PATH_LOADSEARCH refers to the eventual installation directories.
7454 2012-07-07 Eli Zaretskii <eliz@gnu.org>
7456 Support truncation and continuation glyphs on GUI frames, when
7457 fringes are disabled. (Bug#11832)
7458 * xdisp.c (init_iterator): Get dimensions of truncation and
7459 continuation glyphs even if on GUI frames.
7460 Adjust it->last_visible_x on GUI frames when the left or right fringes,
7461 or both, are absent.
7462 (start_display, move_it_in_display_line_to): Handle the case of a
7463 GUI frame without a fringe to display continuation or truncation
7465 (insert_left_trunc_glyphs): Support GUI frames: make sure
7466 truncation glyphs overwrite enough glyphs from the current line to
7467 have sufficient space in pixels.
7468 (display_line): Support truncation and continuation glyphs on GUI
7469 frames. If some spare pixels are left on the line after inserting
7470 the truncation glyphs, fill that space with a stretch glyph of a
7471 suitably computed width.
7473 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
7474 produce_glyphs, to support GUI sessions.
7476 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
7478 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
7480 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
7482 Do not require float-time's arg to fit in time_t (Bug#11825).
7483 This works better on hosts where time_t is unsigned, and where
7484 float-time is applied to the (negative) difference between two times.
7485 * editfns.c (decode_time_components): Last arg is now double *,
7486 not int *, and means to store all the result as a double, without
7487 worrying about whether the seconds part fits in time_t.
7488 All callers changed.
7489 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
7490 All callers changed.
7491 (Ffloat_time): Do not fail merely because the specified time falls
7492 outside of time_t range.
7494 2012-07-07 Glenn Morris <rgm@gnu.org>
7496 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
7497 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
7498 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
7500 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
7502 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
7503 Update dependencies.
7505 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
7507 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7509 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

7511 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
7512 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
7513 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
7514 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
7516 * xfont.c (compare_font_names): Redo to omit the need for casts.
7518 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
7520 * xfns.c (Fx_change_window_property): Doc fix.
7521 * w32fns.c (Fx_change_window_property): Doc fix.
7523 * w32fns.c (Fx_window_property): Accept the same arguments as the
7524 X Windows version. Doc fix.
7525 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
7527 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
7528 Eli Zaretskii <eliz@gnu.org>
7530 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
7531 Windows-specific code from nt/config.nt moved here.
7532 Obsolete settings removed.
7534 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7536 * process.c: Avoid unnecessary calls to gettime.
7537 (wait_reading_process_output): Don't get the time of day
7538 when gobbling data immediately and not waiting, as there's no need
7539 for it in that case. This removes a FIXME.
7541 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
7543 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
7544 is defined (Bug#11768).
7546 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7548 Fix marker debugging code.
7549 * marker.c (byte_char_debug_check): Do not perform the check
7550 if buffer is not multibyte.
7551 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
7552 Call byte_char_debug_check with correct arguments.
7554 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7556 Compile marker debugging code only if ENABLE_CHECKING is defined.
7557 * marker.c (byte_char_debug_check, count_markers):
7558 Use only if ENABLE_CHECKING is defined.
7559 (byte_debug_flag): Remove.
7560 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
7561 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
7563 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7565 Avoid code repetition in marker-related functions.
7566 * marker.c (attach_marker): New function.
7567 (Fset_marker, set_marker_restricted, set_marker_both)
7568 (set_marker_restricted_both): Use it.
7569 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
7570 Consistently rename charno to charpos.
7571 (marker_position): Add eassert.
7572 (marker_byte_position): Convert to eassert.

7591 * window.c (save_window_save): Likewise.
7593 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7595 Do not use Fdelete_overlay in delete_all_overlays
7596 to avoid redundant calls to unchain_overlay.
7597 * buffer.c (drop_overlay): New function.
7598 (delete_all_overlays, Fdelete_overlay): Use it.
7599 * minibuf.c (get_minibuffer): Fix comment.
7601 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7603 Port to OpenBSD 5.1 amd64.
7604 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
7605 This is needed for OpenBSD, and should be harmless on all BSD systems.
7606 Also, include <sys/sysctl.h>, as it should be available on all
7607 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
7608 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
7609 use p_pid member, not kp_proc.pid.
7611 2012-07-06 Glenn Morris <rgm@gnu.org>
7613 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
7615 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
7617 More xmalloc and related cleanup.

7621 * font.c, fontset.c, frame.c, fringe.c, ftfont.c, ftxfont.c, gmalloc.c:
7622 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:

7626 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
7628 Omit needless casts involving void * pointers and allocation.
7629 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
7630 as the former is more robust if P's type is changed.
7631 Prefer xzalloc to xmalloc + memset 0.
7632 Simplify malloc-or-realloc to realloc.
7633 Don't worry about xmalloc returning a null pointer.
7634 Prefer xstrdup to xmalloc + strcpy.
7635 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
7637 * keyboard.c (apply_modifiers_uncached): Prefer local array to
7638 alloca of a constant.
7640 2012-07-05 Eli Zaretskii <eliz@gnu.org>
7642 * xdisp.c (display_line): Fix horizontal pixel coordinates when
7643 hscroll is larger than the line width. Fixes long and futile
7644 looping inside extend_face_to_end_of_line (on a TTY) producing
7645 glyphs that are not needed and thrown away.
7647 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
7649 * marker.c (set_marker_restricted_both): Simplify by using

7659 not defined (Bug#11768).
7660 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
7661 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
7662 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
7663 followed by gtk_box_set_homogeneous (Bug#11768).
7664 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
7665 (update_theme_scrollbar_width, xg_create_scroll_bar):
7666 Use gtk_scrollbar_new (Bug#11768).
7667 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
7668 (is_box_type): New function (Bug#11768).
7669 (xg_tool_item_stale_p): Call is_box_type.

7675 * xdisp.c (window_hscroll_limited): New function.
7676 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
7677 coordinates when window's hscroll is set to insanely large
7680 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
7682 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
7683 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
7685 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
7688 * lisp.h (xzalloc): New prototype. Omit needless casts.

7743 * fileio.c (time_error_value): Check the right error number.
7744 Problem reported by Troels Nielsen in
7745 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.

7749 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
7750 This should be fixed in a better way; see Eli Zaretskii in
7751 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
7752 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
7754 * fileio.c (time_error_value): Rename from special_mtime.
7755 The old name's problems were noted by Eli Zaretskii in
7756 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
7758 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
7759 This variable's comment says Emacs needs at least one GDB-visible
7760 symbol of type enum pvec_type, to work around GDB problems.
7761 The symbol's value doesn't matter.
7763 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
7764 that causes compilation to fail on pre-C99 compilers.
7766 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
7768 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
7769 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
7771 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
7773 * buffer.c (init_buffer_once): Fix initialization of
7774 headers for buffer_defaults and buffer_local_symbols.
7775 Reported by Juanma Barranquero <lekktu@gmail.com>.
7777 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
7779 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
7780 * lisp.h (enum pvec_type): Use fewer bits.
7781 (PSEUDOVECTOR_SIZE_BITS): New constant.
7782 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
7783 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
7784 change in pvec_type.
7785 (PSEUDOVECTOR_TYPEP): New macro.
7786 (TYPED_PSEUDOVECTORP): Use it.
7787 * fns.c (internal_equal): Adapt code to extract pvectype.

7789 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
7790 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
7791 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
7792 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
7793 (sweep_vectors): Use it. Use local var `total_bytes' instead of
7794 abusing vector->header.next.nbytes.
7795 (live_vector_p): Use PVEC_TYPE.
7796 (mark_object): Adapt code to extract pvectype. Use switch.
7798 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7800 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
7801 Tighten new eassert a bit.
7803 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
7805 Fix compilation with --enable-gcc-warnings and -O1
7807 * doprnt.c (doprnt): Change type of tem to int, initialize
7808 to avoid compiler warning. Add eassert.
7809 * search.c (simple_search): Initialize match_byte to avoid
7810 compiler warning. Add eassert.
7812 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7814 Avoid weird behavior with large horizontal scrolls.
7815 Without this change, for example, large hscroll values would
7816 mess up Emacs's display on Fedora 15 x86, presumably due to
7817 overflows in int calculations in the display code.
7818 Also, if buffers had long lines, Emacs would freeze.
7819 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
7820 (set_window_hscroll): New function, containing the old guts of
7821 Fset_window_hscroll. Return the clipped value.
7822 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
7823 This avoids the need to check against PTRDIFF_MAX.
7825 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
7827 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
7829 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
7831 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7833 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
7834 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
7835 since GCC 4.4.6 issues a bogus warning for them.
7837 Fix bugs in file timestamp newness comparisons.
7838 * fileio.c (Ffile_newer_than_file_p):
7839 * lread.c (Fload): Use full timestamp resolution of files,
7840 not just the 1-second resolution, so that files that are only
7841 slightly newer still count as newer.
7842 * fileio.c (Ffile_newer_than_file_p): Don't assume file
7843 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
7845 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
7847 * fileio.c: Improve handling of file time marker. (Bug#11852)
7848 (special_mtime): New function.
7849 (Finsert_file_contents, Fverify_visited_file_modtime):
7850 Use it to set special mtime values consistently.
7852 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
7854 * fileio.c (Finsert_file_contents): Properly handle st_mtime
7855 marker for non-existing file. (Bug#11852)
7857 2012-07-03 Glenn Morris <rgm@gnu.org>
7859 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
7860 and did not make it into globals.h).
7862 2012-07-03 Tom Tromey <tromey@redhat.com>
7864 * window.c (Fset_window_margins, Fset_window_fringes)

7898 * xterm.h: Remove EXFUN.
7900 2012-07-03 Glenn Morris <rgm@gnu.org>
7902 * lisp.h (Frandom): Make it visible to C.
7903 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
7904 buffer for invisible buffers. (Bug#1229)
7906 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7908 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
7909 values which aren't power of 2.
7910 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
7911 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
7914 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
7916 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
7918 * alloc.c (mark_object): Revert part of last patch to use `switch'.
7920 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7922 * alloc.c (allocate_vector_block): Remove redundant
7923 calls to mallopt if DOUG_LEA_MALLOC is defined.
7924 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
7925 avoid calls to mallopt if zero_vector is returned.
7927 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7929 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
7930 is enabled, avoid dereferencing NULL current_sblock if
7933 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7935 Cleanup basic buffer management.
7936 * buffer.h (struct buffer): Change layout to use generic vector
7937 marking code. Fix some comments. Change type of 'clip_changed'
7938 to bitfield. Remove unused #ifndef old.
7939 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
7940 (GET_OVERLAYS_AT): Fix indentation.
7941 (for_each_per_buffer_object_at): New macro.

7945 * alloc.c (allocate_buffer): Adjust to match new layout of
7946 struct buffer. Fix comment.
7947 (mark_overlay): New function.

7949 Lisp area of struct buffer.
7950 (mark_object): Use it. Adjust marking of misc objects
7951 and related comments.
7953 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
7955 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
7956 wrapper that is not needed because the wrapped code is a no-op (zero
7957 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
7958 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
7960 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
7962 * alloc.c (mark_buffer): Simplify. Remove prototype.
7963 (mark_object): Add comment. Reorganize marking of vector-like
7964 objects. Use CHECK_LIVE for all vector-like objects except buffers
7965 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
7966 Avoid redundant calls to mark_vectorlike for bool vectors.
7968 2012-06-30 Glenn Morris <rgm@gnu.org>
7970 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
7972 * epaths.in (PATH_SITELOADSEARCH): New.
7973 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
7974 This is rather than relying on --enable-locallisppath elements
7975 having "site-lisp" in their names. (Bug#10208#25, 11658)
7977 2012-06-30 Eli Zaretskii <eliz@gnu.org>
7979 * w32proc.c (sys_select): Accept and ignore one more argument.
7981 * w32.c (emacs_gnutls_pull): Call select with one more argument.
7983 * sysselect.h [DOS_NT]: Don't include sys/select.h.
7984 (pselect) [!MS_DOS]: Redirect to sys_select.
7986 * sysdep.c: Don't include dos.h and dosfns.h.
7988 * process.c (sys_select):
7989 * msdos.c (sys_select): Accept one more argument and ignore it.
7991 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
7992 adapt data types and code to that.
7995 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
7996 which clashes with the gnulib function of the same name.
7998 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
8000 * font.c (font_style_to_value, font_style_symbolic)
8001 (font_prop_validate_style): Add type checks for values in
8004 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
8006 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
8009 2012-06-29 Eli Zaretskii <eliz@gnu.org>
8011 * xdisp.c (try_window_id): Undo last change.
8013 * w32.c (getwd): Adjust commentary about startup_dir.
8014 (init_environment): Always call sys_access, even in non-MSVC
8015 builds. Don't chdir to the directory of the Emacs executable.
8016 This undoes code from 1997 which was justified by the need to
8017 "avoid conflicts when removing and renaming directories". But its
8018 downside was that every relative file name was being interpreted
8019 relative to the directory of the Emacs executable, which can never
8020 be TRT. In particular, it broke sys_access when called with
8021 relative file names.
8022 (sys_access): Map GetLastError to errno.
8024 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8026 * window.h (struct window): Change type of 'fringes_outside_margins'

8030 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
8033 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
8035 * gnutls.c (emacs_gnutls_handshake):
8036 Add QUIT to make the loop interruptible.
8038 2012-06-29 Glenn Morris <rgm@gnu.org>
8040 * charset.c (init_charset): Make lack of etc/charsets fatal.
8042 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8044 * editfns.c (region_limit): Fix type mismatch.
8046 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8048 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
8049 undefined. Convert from xassert to eassert.
8050 * nsmenu.m: Convert from xassert to eassert.
8051 * nsterm.m: Likewise.
8053 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
8055 * editfns.c (region_limit): Clip to narrowing (bug#11770).
8057 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
8059 Avoid integer overflow on scroll-left and scroll-right.
8060 * window.c (HSCROLL_MAX): New macro.
8061 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
8062 overflow when requested scroll falls outside ptrdiff_t range.
8064 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8066 * window.h (struct window): Change type of 'hscroll',
8067 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
8068 'last_modified' and 'last_overlay_modified' to EMACS_INT.
8069 Adjust users accordingly.
8070 * xdisp.c (try_cursor_movement): Replace type check with eassert.
8071 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
8072 from EMACS_INT to ptrdiff_t.
8073 (make_window): Omit redundant initialization.
8075 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
8077 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
8079 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8081 * window.h (struct window): Change type of 'use_time' and
8082 'sequence_number' from Lisp_Object to int.
8083 * frame.c (make_frame): Adjust users accordingly.
8084 * print.c (print_object): Likewise.
8085 * window.c (select_window, Fwindow_use_time, make_parent_window)
8086 (make_window): Likewise.
8088 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8090 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
8091 enabled with --enable-checking=[all,glyphs] configure option.
8092 Fix GLYPH_DEBUG usage assuming that it may be undefined,
8093 adjust comments accordingly.

8216 Use sprintf return value instead of invoking strlen on result.
8217 In the old days this wasn't portable, since some sprintf
8218 implementations returned char *. But they died out years ago and
8219 Emacs already assumes sprintf returns int.
8220 Similarly for float_to_string.
8221 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

8229 Use sprintf or float_to_string result to avoid need to call strlen.
8230 * data.c (Fnumber_to_string):
8231 Use make_unibyte_string, since the string must be ASCII.
8232 * lisp.h, print.c (float_to_string): Now returns int length.
8233 * term.c (produce_glyphless_glyph):
8234 Use sprintf result rather than recomputing it.
8236 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
8237 * Makefile.in (ALL_CFLAGS):
8238 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

8269 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

8274 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
8275 instead of truncating it to 63 (admittedly a generous limit).

8335 * keyboard.c (kbd_buffer_get_event):
8336 * process.c (Faccept_process_output):

8338 This improves on the previous patch, which introduced a bug
8339 when time_t is unsigned and as wide as intmax_t.
8340 See <http://bugs.gnu.org/9000#51>.

8359 Privately reported by Herbert J. Skuhra.
8360 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.

8405 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
8407 Support higher-resolution time stamps (Bug#9000).
8408 The time stamps are only nanosecond-resolution at the C level,
8409 since that's the best that any real-world system supports now.
8410 But they are picosecond-resolution at the Lisp level, as that's
8411 easy, and leaves room for future OS improvements.
8413 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
8416 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
8417 Don't get current time unless it's needed.
8419 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
8420 now provides it if it's absent.
8421 (start_atimer): Port to higher-res time stamps.
8422 Check for time stamp overflow. Don't get current time more
8423 often than is needed.
8425 * buffer.h (struct buffer): Buffer modtime now has high resolution.
8426 Include systime.h, not time.h.
8427 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
8429 * dired.c: Include stat-time.h.
8430 (Ffile-attributes): File times now have higher resolution.
8432 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
8433 (struct image): Timestamp now has higher resolution.
8435 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
8436 has at least microseconds now. All uses removed.
8437 (update_frame, update_single_window, update_window, update_frame_1)
8438 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
8439 (duration_to_sec_usec): Remove; no longer needed.
8441 * editfns.c (time_overflow): Now extern.
8442 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
8443 (float-time, Fformat_time_string, Fcurrent_time_string)

8447 (decode_time_components, lisp_seconds_argument): New functions.
8448 (make_time): Now static.
8449 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
8450 Report an error if the time is invalid, rather than having the caller
8453 * fileio.c: Include <stat-time.h>
8454 (Fcopy_file): Copy higher-resolution time stamps.
8455 Prefer to set the time stamp via a file descriptor if that works.

8457 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
8458 (Fvisited_file_modtime, Fset_visited_file_modtime):
8459 Support higher-resolution time stamps.
8461 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
8463 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
8465 * image.c (prepare_image_for_display, clear_image_cache)
8466 (lookup_image): Port to higer-resolution time stamps.
8468 * keyboard.c (start_polling, bind_polling_period):
8469 Check for time stamp overflow.
8470 (read_char, kbd_buffer_get_event, timer_start_idle)
8471 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
8472 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
8473 Port to higher-resolution time stamps. Do not assume time_t is signed.
8474 (decode_timer): New function. Timers are now vectors of length 9,
8475 not 8, to accommodate the picosecond component.
8476 (timer_check_2): Use it.
8478 * nsterm.m (select_timeout, timeval_subtract): Remove.
8479 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
8480 as they're a bit more accurate and handle overflow better.
8481 (ns_select): Change prototype to be compatible with pselect.
8482 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
8483 * nsterm.h (ns_select): Adjust prototype.
8485 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
8486 us-resolution time stamps.
8487 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
8489 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
8491 * lisp.h (time_overflow): New decl.
8492 (wait_reading_process_output): First arg is now intmax_t, not int,
8493 to accommodate larger waits.
8495 * process.h (struct Lisp_Process.read_output_delay):
8496 Now counts nanoseconds, not microseconds.
8497 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
8499 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
8500 (wait_reading_process_output):
8501 Port to ns-resolution time stamps.
8502 (Faccept_process_output, wait_reading_process_output):
8503 Check for time stamp overflow. Do not assume time_t is signed.
8504 (select_wrapper): Remove; we now use pselect.
8505 (Fprocess_attributes): Now generates ns-resolution time stamps.
8507 * sysdep.c: Include utimens.h. Don't include utime.h
8508 or worry about struct utimbuf; gnulib does that for us now.
8509 (gettimeofday): Remove; gnulib provides a substitute.
8510 (make_timeval): New function.
8511 (set_file_times): Now sets ns-resolution time stamps.
8512 New arg FD; all uses changed.
8513 (time_from_jiffies, ltime_from_jiffies, get_up_time)
8514 (system_process_attributes):
8515 Now returns ns-resolution time stamp. All uses changed.
8516 Check for time stamp overflow.
8518 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
8519 provides a substitute now.
8521 * systime.h: Include timespec.h rather than sys/time.h and time.h,
8522 since it guarantees struct timespec.
8523 (EMACS_TIME): Now struct timespec, so that we can support
8524 ns-resolution time stamps.
8525 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
8526 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
8527 (EMACS_USECS): Remove.
8528 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
8529 so multiply the arg by 1000 before storing it.
8530 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
8532 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
8533 Port to ns-resolution time stamps.
8534 (EMACS_TIME_NEG_P): Remove; replaced by....
8535 (EMACS_TIME_SIGN): New macro.
8536 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
8537 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
8538 (set_file_times, make_time, lisp_time_argument): Adjust signature.
8539 (make_timeval, make_lisp_time, decode_time_components): New decls.
8540 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
8541 that it mishandled time_t overflow. You can't compare by subtracting!
8542 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
8543 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
8545 * term.c: Include <sys/time.h>.
8546 (timeval_to_Time): New function, for proper overflow wraparound.
8547 (term_mouse_position, term_mouse_click): Use it.
8549 * undo.c (record_first_change): Support higher-resolution time stamps
8551 (Fprimitive_undo): Use them when restoring time stamps.
8553 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
8554 (w32_get_internal_run_time):
8555 Port to higher-resolution Emacs time stamps.
8556 (ltime): Now accepts single 64-bit integer, as that's more convenient
8559 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
8561 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
8562 for compatibility with pselect. Support ns-resolution time stamps.
8564 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
8566 * xselect.c (wait_for_property_change, x_get_foreign_selection):
8567 Check for time stamp overflow, and support ns-resolution time stamps.
8569 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
8570 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
8571 (timeval_subtract): Remove; no longer needed.
8572 (XTflash, XTring_bell, x_wait_for_event):
8573 Port to ns-resolution time stamps. Don't assume time_t is signed.
8575 2012-06-22 Chong Yidong <cyd@gnu.org>
8577 * xdisp.c (x_consider_frame_title): Revert last change.
8579 2012-06-22 Eli Zaretskii <eliz@gnu.org>
8581 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
8582 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
8583 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
8584 staticidx goes up to 1597 out of 1600 = 0x640.)
8586 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
8588 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
8589 Otherwise, the umask might be mistakenly 0 while handling input signals.
8591 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
8593 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

8858 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
8859 Use an inline function on all platforms when using the union type,
8860 since this is simpler and 'static inline' can be used portably

9005 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
9006 would mishandle a string argument "Xc" if X was a multibyte
9007 character of length 2: it would truncate after X's first byte
9008 rather than including all of X.

9077 bitfields where appropriate, remove unused fields.
9078 * window.h (struct window): Remove unused 'last_mark_x' and
9079 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
9080 change its type from Lisp_Object to bitfield.
9081 Change type of 'force_start', 'optional_new_start',
9082 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
9083 fields from Lisp_Object to bitfield. Adjust users accordingly.
9085 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
9087 Pacify gcc -Wdouble-precision when using Xaw.
9088 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
9089 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
9090 Use 'float' consistently, rather than 'float' in most places
9091 and 'double' in a couple of places.
9093 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9095 * xdisp.c (handle_stop): Detect whether we have overlay strings
9096 loaded by testing it->current.overlay_string_index to be
9097 non-negative, instead of checking whether n_overlay_strings is
9098 positive. (Bug#11587)
9100 2012-05-31 Chong Yidong <cyd@gnu.org>
9102 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
9104 * doc.c (Fsubstitute_command_keys): Doc fix.
9106 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9108 * search.c (search_buffer): Remove calls to
9109 r_alloc_inhibit_buffer_relocation, as it is now called by
9110 maybe_unify_char, which was the cause of relocation of buffer text
9113 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9115 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
9116 for the duration of call to load_charset, to avoid problems with
9117 callers of maybe_unify_char that access buffer text through C
9120 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
9121 decrement the inhibition flag, instead of just setting or
9124 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
9126 Remove obsolete '#define static' cruft.
9127 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
9128 This #undef was "temporary" in 2000; it is no longer needed
9129 now that '#define static' has gone away.
9130 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
9131 (gray_bitmap_bits): Remove; no longer needed.
9132 All uses replaced with definiens.
9133 * xterm.c: Include "bitmaps/gray.xbm".
9135 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
9137 Clean up __executable_start, monstartup when --enable-profiling.
9138 The following changes affect the code only when profiling.
9139 * dispnew.c (__executable_start): Rename from safe_bcopy.
9140 Define only on platforms that need it.
9141 * emacs.c: Include <sys/gmon.h> when profiling.
9142 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
9143 (__executable_start): Remove decl, since lisp.h does it now.
9144 (safe_bcopy): Remove decl; no longer has that name.
9145 (main): Coalesce #if into single bit of code, for simplicity.
9146 Cast pointers to uintptr_t, since standard libraries want integers
9148 * lisp.h (__executable_start): New decl.
9150 2012-05-31 Glenn Morris <rgm@gnu.org>
9152 * image.c (Fimagemagick_types): Doc fix.

9171 * lread.c (read1): Tiny simplification.
9173 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
9175 Do not create empty overlays with the evaporate property (Bug#9642).
9176 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
9177 Bug#9642, but explicitly check that the buffer the overlay would
9178 be moved to is live and rearrange lines to make sure that errors
9179 will not put the overlay in an inconsistent state.
9180 (Fdelete_overlay): Cosmetics.
9182 2012-05-28 Eli Zaretskii <eliz@gnu.org>
9184 * w32term.c (my_bring_window_to_top): New function.
9185 (x_raise_frame): Use handle returned by DeferWindowPos, which
9186 could be different from the original one.
9187 Call my_bring_window_to_top instead of my_set_foreground_window.
9190 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
9191 by calling BringWindowToTop.
9193 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
9194 (WM_EMACS_END): Increase by one.
9196 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
9198 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
9199 This avoids undefined behavior that might cause the eassert
9200 to not catch an out-of-range value.
9202 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
9204 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
9205 Update dependencies.
9207 2012-05-27 Eli Zaretskii <eliz@gnu.org>
9209 * bidi.c (bidi_mirror_char): Fix last change.
9211 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
9213 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
9214 when referring to sectname field in printf format.
9216 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
9218 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
9219 Only r_alloc_inhibit_buffer_relocation needed to be added;
9220 the others were already declared.
9222 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
9223 before checking whether it's out of range. Put the check inside
9225 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
9227 2012-05-27 Ken Brown <kbrown@cornell.edu>
9229 * callproc.c (Fcall_process): Restore a line that was accidentally
9230 commented out in the 2011-02-13 change (bug#11547).
9232 2012-05-27 Eli Zaretskii <eliz@gnu.org>
9234 * lisp.h [REL_ALLOC]: Add prototypes for external functions
9235 defined on ralloc.c.
9237 * buffer.c [REL_ALLOC]: Remove prototypes of
9238 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
9239 they are now on lisp.h.
9241 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
9243 * search.c (search_buffer): Use it to inhibit relocation of buffer
9244 text while re_search_2 is doing its job, because re_search_2 is
9245 passed C pointers to buffer text. (Bug#11519)
9247 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
9250 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
9251 state after an additional call to move_it_in_display_line_to, keep
9252 the values of it->max_ascent and it->max_descent found for the
9254 (pos_visible_p): Revert the comparison against bottom_y to what it
9255 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
9258 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
9260 Fix coding-related core dumps with gcc -ftrapv.
9261 The code was computing A - B, where A and B are pointers, and B is
9262 random garbage. This can lead to core dumps on platforms that
9263 have special pointer registers, and it also leads to core dumps on
9264 x86-64 when compiled with gcc -ftrapv. The fix is to compute
9265 A - B only when B is initialized properly.
9266 * coding.c (coding_set_source, coding_set_destination): Return void.
9267 (coding_change_source, coding_change_destinations): New functions,
9268 with the old behaviors of coding_set_source and coding_set_destination.
9269 All callers that need an offset changed to use these new functions.
9271 2012-05-26 Glenn Morris <rgm@gnu.org>
9273 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
9275 2012-05-26 Eli Zaretskii <eliz@gnu.org>
9277 Extend mouse support on W32 text-mode console.
9278 * xdisp.c (draw_row_with_mouse_face):
9279 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
9281 * w32console.c: Include window.h.
9282 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
9284 (initialize_w32_display): Initialize mouse-highlight data.
9286 * w32inevt.c: Include termchar.h and window.h.
9287 (do_mouse_event): Support mouse-autoselect-window. When the mouse
9288 moves, call note_mouse_highlight. If help_echo changed, call
9289 gen_help_event to produce help-echo message in the echo area.
9290 Call clear_mouse_face if mouse_face_hidden is set in the mouse
9293 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
9295 * lread.c (read1): Simplify slightly to avoid an overflow warning
9296 with GCC 4.7.0 on x86-64.
9298 2012-05-26 Eli Zaretskii <eliz@gnu.org>
9300 * bidi.c (bidi_mirror_char): Revert last change: an int is
9301 definitely wide enough here.
9303 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
9305 Fix integer width and related bugs (Bug#9874).
9306 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
9307 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
9308 (string_bytes, check_sblock, allocate_string_data):
9309 (compact_small_strings, Fmake_bool_vector, make_string)
9310 (make_unibyte_string, make_multibyte_string)
9311 (make_string_from_bytes, make_specified_string)
9312 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
9313 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
9315 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9316 (allocate_pseudovector):
9317 Use int, not EMACS_INT, where int is wide enough.
9318 (inhibit_garbage_collection, Fgarbage_collect):
9319 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9320 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
9321 int might not be wide enough.
9322 (bidi_cache_search, bidi_cache_find, bidi_init_it)
9323 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
9324 (bidi_at_paragraph_end, bidi_find_paragraph_start)
9325 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
9326 (bidi_level_of_next_char, bidi_move_to_visually_next):
9327 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9328 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
9329 (Fkill_buffer, Fset_buffer_major_mode)
9330 (advance_to_char_boundary, Fbuffer_swap_text)
9331 (Fset_buffer_multibyte, overlays_at, overlays_in)
9332 (overlay_touches_p, struct sortvec, record_overlay_string)
9333 (overlay_strings, recenter_overlay_lists)
9334 (adjust_overlays_for_insert, adjust_overlays_for_delete)
9335 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
9336 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
9337 (Foverlay_recenter, last_overlay_modification_hooks_used)
9338 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
9339 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9340 (validate_region): Omit unnecessary test for b <= e,
9341 since that's guaranteed by the previous test.
9342 (adjust_overlays_for_delete): Avoid pos + length overflow.
9343 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
9344 (report_overlay_modification):
9345 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9346 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
9347 Omit pointer cast, which isn't needed anyway, and doesn't work
9348 after the EMACS_INT -> ptrdiff_t change.
9349 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
9350 * buffer.h: Adjust decls to match defn changes elsewhere.
9351 (struct buffer_text, struct buffer):

9353 Use EMACS_INT, not int, where int might not be wide enough.
9354 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
9355 not int, to avoid needless 32-bit limit on 64-bit hosts.
9356 (exec_byte_code): Use tighter memory-full test, one that checks
9357 for alloca overflow. Don't compute the address of the object just
9358 before an array, as that's not portable. Use EMACS_INT, not
9359 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
9360 * callint.c (Fcall_interactively):
9361 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9362 * callproc.c (call_process_kill, Fcall_process):
9363 Don't assume pid_t fits into an Emacs fixnum.
9364 (call_process_cleanup, Fcall_process, child_setup):

9366 (call_process_cleanup, Fcall_process, delete_temp_file)
9367 (Fcall_process_region):
9368 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9369 (Fcall_process): Simplify handling of volatile integers.
9370 Use int, not EMACS_INT, where int will do.
9371 * casefiddle.c (casify_object, casify_region, operate_on_word)
9372 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
9373 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9374 (casify_object): Avoid integer overflow when overallocating buffer.
9375 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
9376 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
9377 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
9378 * category.h (CATEGORYP): Don't assume arg is nonnegative.
9379 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
9380 integers are now checked earlier. All uses replaced with XINT.
9382 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9383 For CCL_MapSingle, check that content and value are in int range.
9384 (ccl_driver, Fregister_code_conversion_map):
9385 Check that Vcode_version_map_vector is a vector.
9386 (resolve_symbol_ccl_program): Check that vector header is in range.
9387 Always copy the vector, so that we can check its contents reliably
9388 now rather than having to recheck each instruction as it's being
9389 executed. Check that vector words fit in 'int'.
9390 (ccl_get_compiled_code, Fregister_ccl_program)
9391 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
9392 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
9393 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
9394 contents are in range.
9395 (Fccl_execute_on_string): Check that status is in range.
9396 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
9397 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
9398 Accept and return EMACS_INT, not int, because callers can pass values
9400 (c_string_width, strwidth, lisp_string_width, chars_in_text)
9401 (multibyte_chars_in_text, parse_str_as_multibyte)
9402 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
9403 (str_as_unibyte, str_to_unibyte, string_count_byte8)
9404 (string_escape_byte8, Fget_byte):
9405 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9406 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
9407 avoid mishandling large integers.
9408 * character.h: Adjust decls to match defn changes elsewhere.
9409 * charset.c (load_charset_map_from_file, find_charsets_in_text)
9410 (Ffind_charset_region):
9411 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9412 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
9413 (load_charset_map_from_vector, Fdefine_charset_internal):
9414 Don't assume fixnum fits in int.
9415 (load_charset_map_from_vector, Fmap_charset_chars):
9416 Remove now-unnecessary CHECK_NATNUMs.
9417 (Fdefine_charset_internal): Check ranges here, more carefully.
9418 Don't rely on undefined behavior with signed left shift overflow.
9419 Don't assume unsigned int fits into fixnum, or that fixnum fits
9420 into unsigned int. Don't require max_code to be a valid fixnum;
9421 that's not true for gb10830 4-byte on a 32-bit host. Allow
9422 invalid_code to be a cons, for the same reason. Require code_offset
9423 to be a character. Avoid int overflow if max_char is close
9425 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
9426 this is intended anyway and avoids some undefined behavior.
9427 (load_charset_map): Pass unsigned, not int, as 2nd arg of
9428 INDEX_TO_CODE_POINT, as that's what it expects.
9429 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
9430 * charset.h (DECODE_CHAR): Return int, not unsigned;
9431 this is what was intended anyway, and it avoids undefined behavior.
9432 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
9433 integer-overflow issues.
9434 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
9435 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
9436 where the argument is EMACS_INT, and this behavior is not intended.
9437 * chartab.c (Fmake_char_table, Fset_char_table_range)
9438 (uniprop_get_decoder, uniprop_get_encoder):
9439 Don't assume fixnum fits in int.
9440 * cmds.c (move_point): New function, that does the gist of
9441 Fforward_char and Fbackward_char, but does so while checking
9442 for integer overflow more accurately.
9443 (Fforward_char, Fbackward_char): Use it.
9444 (Fforward_line, Fend_of_line, internal_self_insert)
9445 (internal_self_insert):
9446 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9447 Fix a FIXME, by checking for integer overflow when calculating
9448 target_clm and actual_clm.
9449 * coding.c (detect_coding_XXX, encode_coding_XXX, CODING_DECODE_CHAR)

9478 (Funencodable_char_position, Fcheck_coding_systems_region)
9479 (get_translation, handle_composition_annotation, consume_chars):
9480 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9481 (consume_chars): Rewrite to not calculate an address outside buffer.
9482 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
9483 Don't access memory outside of the args array.
9484 (Fdefine_coding_system_internal): Check for charset-id overflow.
9485 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
9486 result of ENCODE_CHAR.
9487 * coding.h: Adjust decls to match defn changes elsewhere.
9488 (struct coding_system):

10199 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
10201 2012-05-18 Eli Zaretskii <eliz@gnu.org>
10203 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
10205 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
10206 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
10208 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
10209 reference to image_cache->refcount.
10210 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
10212 2012-05-17 Juri Linkov <juri@jurta.org>
10214 * search.c (Fword_search_regexp, Fword_search_backward)
10215 (Fword_search_forward, Fword_search_backward_lax)
10216 (Fword_search_forward_lax): Move functions to isearch.el
10217 (bug#10145, bug#11381).
10219 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
10221 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
10223 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
10225 * lread.c (init_obarray): Declare Qt and Qnil as special.
10227 2012-05-14 Glenn Morris <rgm@gnu.org>
10229 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
10230 Put "libexec" before "bin", for the sake of init_callproc_1.
10232 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
10234 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
10236 * unexaix.c: Port to more-recent AIX compilers.
10237 (report_error, report_error_1, make_hdr, copy_sym)
10238 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
10239 Make arguments const char *, not char *, to avoid violations of C
10240 standard and to fix some AIX warnings reported by Gilles Pion.
10242 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10244 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
10245 already have overlays loaded.
10246 (handle_single_display_spec): Before returning without displaying
10247 fringe bitmap, synchronize the bidi iterator with the main display
10248 iterator, by calling iterate_out_of_display_property.
10249 (iterate_out_of_display_property): Detect buffer iteration by
10250 testing that it->string is a Lisp string.
10251 (get_next_display_element): When the current object is exhausted,
10252 and there's something on it->stack, call set_iterator_to_next to
10253 proceed with what's on the stack, instead of returning zero.
10254 (set_iterator_to_next): If called at the end of a Lisp string,
10255 proceed to consider_string_end without incrementing string
10256 position. Don't increment display vector index past the end of
10257 the display vector. (Bug#11417)
10258 (pos_visible_p): Don't report a position visible when move_it_to
10259 stopped at the last line of window, which happens to be scanned
10260 backwards by the bidi iteration. (Bug#11464)
10262 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10264 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
10265 and right-margin display specs even if the spec is invalid or we
10266 are on a TTY, and thus unable to display on the fringes.
10267 That's because the text with the property will not be displayed anyway,
10268 so we need to signal to the caller that this is a "replacing"
10269 display spec. This fixes display when the spec is invalid or we
10272 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
10274 * unexaix.c (make_hdr): Fix typo in prototype.
10275 This bug broke the build on AIX. Problem reported by Gilles Pion.
10277 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
10279 * keyboard.c (kbd_buffer_get_event): Read special events also in
10280 batch mode. (Bug#11415)
10282 2012-05-12 Glenn Morris <rgm@gnu.org>
10284 * ns.mk: Update for ns_appbindir no longer having trailing "/".
10286 2012-05-12 Eli Zaretskii <eliz@gnu.org>
10288 * lisp.mk (lisp): Add newcomment.elc.
10290 2012-05-12 Glenn Morris <rgm@gnu.org>
10292 * Makefile.in (MKDIR_P): New, set by configure.
10293 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
10295 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
10297 Remove unused function hourglass_started.
10298 * dispextern.h (hourglass_started):
10299 * w32fns.c (hourglass_started):
10300 * xdisp.c (hourglass_started): Remove.
10302 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
10304 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
10305 Update dependencies.
10307 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
10309 * xgselect.c (xg_select): Put maxfds+1 into a var.
10310 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
10312 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
10314 2012-05-10 Dave Abrahams <dave@boostpro.com>
10316 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
10317 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
10319 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
10321 * dbusbind.c (xd_registered_buses): New internal Lisp object.
10322 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
10323 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
10324 Initialize xd_registered_buses.
10326 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
10328 Untag more efficiently if USE_LSB_TAG.
10329 This is based on a proposal by YAMAMOTO Mitsuharu in
10330 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
10331 For an admittedly artificial (nth 8000 longlist) benchmark on
10332 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
10333 Emacs's overall text size by 1%.
10334 * lisp.h (XUNTAG): New macro.
10335 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
10336 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
10337 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
10338 * eval.c (Fautoload):
10339 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
10340 * frame.h (XFRAME): Use XUNTAG.
10342 Port recent dbusbind.c changes to 32-bit --with-wide-int.
10343 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
10344 Remove unportable assumptions about print widths of types like
10346 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
10347 intptr_t when converting between pointer and integer, to avoid GCC
10348 warnings about wrong width.
10350 2012-05-09 Eli Zaretskii <eliz@gnu.org>
10352 * w32proc.c (new_child): Force Windows to reserve only 64KB of
10353 stack for each reader_thread, instead of defaulting to 8MB
10354 determined by the linker. This avoids failures in creating
10355 subprocesses on Windows 7, see the discussion in this thread:
10356 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
10358 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
10360 Fix up display of the *Minibuf-0* buffer in the mini window.
10361 * keyboard.c (read_char): Don't clear the echo area if there's no
10363 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
10364 contents of *Minibuf-0*) if there's no message displayed in its stead.
10366 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
10368 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
10371 2012-05-06 Chong Yidong <cyd@gnu.org>
10373 * lisp.mk (lisp): Update.
10375 2012-05-05 Jim Meyering <meyering@redhat.com>
10377 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
10379 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
10381 * data.c (PUT_ERROR): New macro.
10382 (syms_of_data): Use it. Add new error type `user-error'.
10383 * undo.c (user_error): New function.
10384 (Fprimitive_undo): Use it.
10385 * print.c (print_error_message): Adjust print style for `user-error'.
10386 * keyboard.c (user_error): New function.
10387 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
10389 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
10391 Do not limit current-time-string to years 1000..9999.
10392 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
10393 (Fcurrent_time_string): Support any year that is supported by the
10394 underlying localtime representation. Don't use asctime, as it
10395 has undefined behavior for years outside the range -999..9999.
10397 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
10399 Fix race conditions involving setenv, gmtime, localtime, asctime.
10400 Without this fix, interrupts could mess up code that uses these
10401 nonreentrant functions, since setting TZ invalidates existing
10402 tm_zone or tzname values, and since most of these functions return
10403 pointers to static storage.
10404 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
10405 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
10406 Grow the critical sections to include not just invoking
10407 localtime/gmtime, but also accessing these functions' results
10408 including their tm_zone values if any, and any related TZ setting.
10409 (format_time_string): Last arg is now struct tm *, not struct tm **,
10410 so that the struct tm is saved in the critical section.
10411 All callers changed. Simplify allocation of initial buffer, partly
10412 motivated by the fact that memory allocation needs to be outside
10413 the critical section.
10415 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
10417 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
10418 with RESET_INTERVAL.
10420 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
10421 Remove duplicated buffer name initialization.
10423 2012-05-02 Jim Meyering <jim@meyering.net>
10425 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
10427 * xfns.c (x_window): Use xstrdup (Bug#11375).
10429 2012-05-02 Eli Zaretskii <eliz@gnu.org>
10431 * xdisp.c (pos_visible_p): If already at a newline from the
10432 display string before the 'while' loop, don't walk back the glyphs
10433 from it3.glyph_row. Solves assertion violation when the display
10434 string begins with a newline (egg.el). (Bug#11367)
10436 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
10438 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
10441 2012-05-01 Glenn Morris <rgm@gnu.org>
10443 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
10444 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
10445 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
10446 All were removed before 23.1.
10448 * dispnew.c: Remove HAVE_LIBNCURSES test;
10449 it is always true on relevant platforms.
10451 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
10452 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
10454 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
10456 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
10458 * .gdbinit (xpr): Remove checks for no longer existing misc types.
10459 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
10462 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
10464 Do not avoid creating empty evaporating overlays (Bug#9642).
10465 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
10466 That is, do not delete an evaporating overlay if it becomes
10467 empty after its bounds are adjusted to fit within its buffer.
10468 This fix caused other problems, and I'm reverting it until we get
10469 to the bottom of them.
10471 2012-04-27 Chong Yidong <cyd@gnu.org>
10473 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
10475 2012-04-27 Eli Zaretskii <eliz@gnu.org>
10477 * xdisp.c (pos_visible_p): If the window start position is beyond
10478 ZV, start the display from buffer beginning. Prevents assertion
10479 violation in init_iterator when the minibuffer window is scrolled
10480 via the scroll bar.
10482 * window.c (window_scroll_pixel_based): Likewise.
10484 2012-04-27 Chong Yidong <cyd@gnu.org>
10486 * keymap.c (where_is_internal): Doc fix (Bug#10872).
10488 2012-04-27 Glenn Morris <rgm@gnu.org>
10490 * fileio.c (Fcopy_file, Fset_file_selinux_context):
10491 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
10493 2012-04-27 Eli Zaretskii <eliz@gnu.org>
10495 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
10496 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
10498 2012-04-26 Eli Zaretskii <eliz@gnu.org>
10500 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
10501 display element, check also the underlying string or buffer
10502 character. (Bug#11341)
10504 * w32menu.c: Include w32heap.h.
10505 (add_menu_item): If the call to AppendMenuW (via
10506 unicode_append_menu) fails, disable Unicode menus only if we are
10507 running on Windows 9X/Me.
10509 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
10511 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
10512 (xgetint): Add missing shift for LSB tags.
10514 2012-04-24 Martin Rudalics <rudalics@gmx.at>
10516 * keyboard.c (read_char): Don't wipe echo area for select window
10517 events: These might get delayed via `mouse-autoselect-window'
10520 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
10522 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
10523 manipulation of :loaded-from data.
10525 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
10527 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
10528 now a cons (bug#11311).
10530 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
10532 Do not create empty overlays with the evaporate property (Bug#9642).
10533 * buffer.c (Fmove_overlay): Delete an evaporating overlay
10534 if it becomes empty after its bounds are adjusted to fit within
10535 its buffer. Without this fix, in a nonempty buffer (let ((o
10536 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
10537 yields an empty overlay that has the evaporate property, which is
10538 not supposed to happen.
10540 Fix minor GTK3 problems found by static checking.
10541 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
10542 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
10543 (struct _EmacsFixedClass, emacs_fixed_get_type):
10544 Move decls here from emacsgtkfixed.h, since they needn't be public.
10545 (emacs_fixed_get_type): Now static.
10546 (emacs_fixed_class_init): Omit unused local.
10547 (emacs_fixed_child_type): Remove; unused.

10549 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
10550 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
10551 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
10552 (EMACS_FIXED_GET_CLASS): Remove; unused.
10553 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
10555 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
10556 Problem reported by Juanma Barranquero for Windows -Wunused-function.
10558 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
10560 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
10561 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
10562 (__malloc_size_t, __malloc_ptrdiff_t):
10563 Remove. All uses removed, replaced by the definiens if needed,
10564 since we can assume C89 or better now.
10565 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

10573 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
10574 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
10575 Define using prototypes, not old style.
10576 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
10577 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
10578 (align): Don't assume that signed integer overflow wraps around.
10579 Omit unused local var.
10580 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
10581 (_free_internal_nolock, memalign, mallochook, reallochook):
10582 Omit no-longer-needed casts.
10583 (valloc): Use getpagesize, not __getpagesize.
10584 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
10585 (struct hdr): The 'magic' member is now size_t, not unsigned long.
10587 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
10589 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
10591 Move functions from C to Lisp. Make non-blocking method calls
10592 the default. Implement further D-Bus standard interfaces.
10594 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.

10649 2012-04-22 Leo Liu <sdl.web@gmail.com>
10651 * sysdep.c (list_system_processes): Support Darwin (Bug#5725).
10653 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
10655 * sysdep.c [__FreeBSD__]: Minor cleanups.
10656 (list_system_processes, system_process_attributes) [__FreeBSD__]:
10657 Use Emacs indenting style more consistently. Avoid some casts.
10658 Use 'double' consistently rather than mixing 'float' and 'double'.
10660 2012-04-21 Eduard Wiebe <usenet@pusto.de>
10662 * sysdep.c (list_system_processes, system_process_attributes):
10663 Add implementation for FreeBSD (Bug#5243).

10669 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
10671 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
10672 It is never used otherwise.
10674 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
10676 * print.c (print_preprocess): Only check print_depth if print-circle
10678 (print_object): Check for cycles even when print-circle is nil and
10679 print-gensym is t, but only check print_depth if print-circle is nil.
10681 2012-04-20 Chong Yidong <cyd@gnu.org>
10683 * process.c (wait_reading_process_output): If EIO occurs on a pty,
10684 set the status to "failed" and ensure that sentinel is run.
10686 2012-04-20 Glenn Morris <rgm@gnu.org>
10688 * process.c (Fset_process_inherit_coding_system_flag)
10689 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

10699 farther than the first row after the header line, if any.
10700 Don't consider the header-line row as "partially visible", even if
10701 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
10703 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

10715 * process.c: Ignore -Wstrict-overflow to work around GCC bug 52904.
10716 * regex.c: Ignore -Wstrict-overflow. If !emacs, also ignore
10717 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
10718 -Wunused-result, -Wunused-variable. This should go away once
10719 the Emacs and Gnulib regex code is merged.
10720 (xmalloc, xrealloc): Now static.
10722 2012-04-17 Paul Eggert <eggert@cs.ucla.edu>

10739 New extern decls, to avoid calling undeclared functions.
10740 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
10741 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
10742 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
10743 (NEED_MEM_INSERT): New macro.
10744 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
10745 Remove one incorrect comment and fix another.

10759 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
10760 Remove decls. This fixes an "It stinks!".
10762 * alloc.c (which_symbols): Fix alignment issue / type clash.
10764 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
10766 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
10767 (struct Lisp_Misc_Any): Likewise.
10768 (struct Lisp_Free): Likewise.
10769 * alloc.c (union aligned_Lisp_Symbol): Define.

10781 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
10782 * s/netbsd.h, s/sol2-6.h:
10783 Remove definition of GC_MARK_STACK, since the default now works.
10784 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
10785 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
10786 no longer the default.
10787 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
10789 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
10791 * lread.c (lisp_file_lexically_bound_p):
10792 Fix hang at ";-*-\n" (bug#11238).
10794 2012-04-14 Eli Zaretskii <eliz@gnu.org>
10796 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
10797 "unchanged" if its end.pos is beyond ZV. (Bug#11199)

10810 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
10812 2012-04-11 Daniel Colascione <dancol@dancol.org>
10814 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
10815 against is gone. It's better to use vfork now so that when Cygwin
10816 gains a new, working vfork, we use it automatically (bug#10398).
10818 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

10838 * w32.c (w32_delayed_load): Record the full path of the library
10839 being loaded (bug#10424).
10841 2012-04-09 Glenn Morris <rgm@gnu.org>
10843 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
10844 not just in the obarray, before snarfing them. (Bug#11036)

10861 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
10862 attempts per process (connection).
10864 2012-04-09 Chong Yidong <cyd@gnu.org>
10866 * eval.c (Fuser_variable_p, user_variable_p_eh)
10867 (lisp_indirect_variable): Functions deleted.
10868 (Fdefvar): Caller changed.
10870 * callint.c (Finteractive, Fcall_interactively):
10871 * minibuf.c (Fread_variable): Callers changed.
10873 2012-04-09 Eli Zaretskii <eliz@gnu.org>
10875 * xdisp.c (set_cursor_from_row): If the display string appears in
10876 the buffer at position that is closer to point than the position
10877 after the display string, display the cursor on the first glyph of
10878 the display string. Fixes cursor display when a 'display' text
10879 property immediately follows invisible text. (Bug#11094)
10881 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
10883 composite.c: use 'double' consistently
10884 * composite.c (get_composition_id): Use 'double' consistently
10885 instead of converting 'float' to 'double' and vice versa; this is
10886 easier to understand and avoids a GCC warning.
10888 2012-04-09 Glenn Morris <rgm@gnu.org>
10890 * Makefile.in: Generate leim-list with bootstrap-emacs, in
10891 preparation for dumping it with emacs. (Bug#4789)

10913 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
10914 (mark_memory): Mark Lisp_Objects only if pointers might hide in
10915 objects, as mark_maybe_pointer will catch them otherwise.
10916 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
10917 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

10929 (GLOBAL_SOURCES): Add xml.c.
10930 ($(BLD)/xml.$(O)): New dependency list.
10932 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
10933 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
10934 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
10935 [!WINDOWSNT]: New macros.
10936 (init_libxml2_functions, libxml2_loaded_p): New functions.
10937 (parse_region): Call fn_xmlCheckVersion instead of using the macro
10938 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
10939 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
10940 Calls xmlCleanupParser only if libxml2 was loaded (or statically
10942 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
10943 Call init_libxml2_functions before calling libxml2 functions.
10944 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
10946 * emacs.c: Don't include libxml/parser.h.
10947 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
10948 xmlCleanupParser directly.

10952 2012-04-07 Eli Zaretskii <eliz@gnu.org>
10954 * indent.c (Fvertical_motion): If there is a display string at
10955 point, use it.vpos to compute how many lines to backtrack after
10956 move_it_to point. (Bug#11133)
10958 2012-04-06 Eli Zaretskii <eliz@gnu.org>
10960 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
10961 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
10962 about subtle differences between FETCH_CHAR* and STRING_CHAR*
10963 macros related to unification of CJK characters. For the details,
10964 see the discussion following the message here:
10965 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
10967 2012-04-04 Chong Yidong <cyd@gnu.org>
10969 * keyboard.c (Vdelayed_warnings_list): Doc fix.
10971 2012-04-01 Eli Zaretskii <eliz@gnu.org>
10973 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

10981 2012-03-31 Eli Zaretskii <eliz@gnu.org>
10983 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
10984 position we get to after a call to move_it_to fails the
10985 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
10986 only if we wind up in a string from display property. (Bug#11063)
10988 * window.c (Fdelete_other_windows_internal): Invalidate the row
10989 and column information about mouse highlight, so that redisplay
10990 restores it after reallocating the glyph matrices. (Bug#7464)
10992 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
10993 string comes from a `display' text property, use the buffer
10994 position of that property as if we actually saw that position in
10996 (move_it_by_lines): Remove the assertion that
10997 "it->current_x == 0 && it->hpos == 0" which can be legitimately
10998 violated when there's a before-string at the beginning of a line.
11001 2012-03-30 Eli Zaretskii <eliz@gnu.org>
11003 * xdisp.c (append_space_for_newline): If the default face was
11004 remapped, use the remapped face for the appended newline.
11005 (extend_face_to_end_of_line): Use the remapped default face for
11006 extending the face to the end of the line.
11007 (display_line): Call extend_face_to_end_of_line when the default
11008 face was remapped. (Bug#11068)
11010 2012-03-29 Eli Zaretskii <eliz@gnu.org>
11012 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

11030 * keyboard.c (Vselection_inhibit_update_commands): New variable.
11031 (command_loop_1): Use it; inhibit selection update for

11036 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
11038 2012-03-25 Kenichi Handa <handa@m17n.org>
11040 * dispextern.h (struct glyph): Change the bit length of
11041 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
11043 2012-03-24 Eli Zaretskii <eliz@gnu.org>
11045 * s/ms-w32.h (tzname): Include time.h before redirecting to

11054 !SYNC_INPUT. (Bug#11080)
11056 2012-03-23 Eli Zaretskii <eliz@gnu.org>
11058 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
11059 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
11060 when fetching a multibyte character consumes more bytes than
11061 CHAR_BYTES returns, due to unification of CJK characters in
11062 string_char. (Bug#11073)
11064 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
11066 * process.c (wait_reading_process_output): Handle pty disconnect
11067 by refraining from sending oneself a SIGCHLD (bug#10933).
11069 2012-03-22 Chong Yidong <cyd@gnu.org>
11071 * dispextern.h (struct it): New member string_from_prefix_prop_p.
11073 * xdisp.c (push_prefix_prop): Rename from push_display_prop.

11095 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
11096 it fit in a valid range (Bug#11003).
11098 2012-03-18 Eli Zaretskii <eliz@gnu.org>
11100 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
11101 that is not from display property, accept the row as a "cursor
11102 row" if one of the string's character has a non-nil `cursor'
11103 property. Fixes cursor positioning when there are newlines in
11104 overlay strings, e.g. in icomplete.el. (Bug#11035)
11106 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
11108 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).

11137 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
11140 2012-03-03 Glenn Morris <rgm@gnu.org>
11142 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
11144 2012-03-02 Eli Zaretskii <eliz@gnu.org>

11147 position past the first glyph_row that ends at ZV. (Bug#10902)
11148 (redisplay_window, next_element_from_string): Fix typos in
11150 (redisplay_window): Pass to move_it_vertically the margin in
11151 pixels, not in screen lines.
11153 2012-03-02 Glenn Morris <rgm@gnu.org>
11155 * buffer.c (buffer-list-update-hook): Doc fix.
11157 2012-02-29 Eli Zaretskii <eliz@gnu.org>
11159 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
11160 push_it before setting up the iterator for the first overlay
11161 string, even if we have an empty string loaded.
11162 (next_overlay_string): If there's an empty string on the iterator
11163 stack, pop the stack. (Bug#10903)
11165 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
11167 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
11168 Suggested by Stefan Monnier in
11169 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
11170 * alloc.c (widen_to_Lisp_Object): New static function.
11171 (mark_memory): Also mark Lisp_Objects by fetching pointer words
11172 and widening them to Lisp_Objects. This would work even if
11173 USE_LSB_TAG is defined and wide integers are used, which might
11174 happen in a future version of Emacs.
11176 2012-02-25 Chong Yidong <cyd@gnu.org>
11178 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

11183 before saving to clipboard manager.
11185 2012-02-24 Chong Yidong <cyd@gnu.org>
11187 * keyboard.c (process_special_events): Handle all X selection
11188 requests in kbd_buffer, not just the next one (Bug#8869).
11190 2012-02-23 Chong Yidong <cyd@gnu.org>
11192 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
11193 call when setting menu-bar-lines and tool-bar-lines parameters.
11194 (unwind_create_frame_1): New helper function.
11196 * window.c (inhibit_window_configuration_change_hook): New var.

11207 * fileio.c (Vfile_name_handler_alist): Doc fix.
11209 * buffer.c (Fget_file_buffer): Protect against invalid file
11210 handler return value.

11214 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
11215 when computing $valmask.
11217 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
11218 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
11219 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
11220 It's useless in that case, and it can cause problems on hosts
11221 that allocate halves of EMACS_INT values separately.
11222 Reported by Dan Horák. Diagnosed by Andreas Schwab in
11223 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
11224 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
11225 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
11226 it avoids undefined behavior on hosts where shifting right by more
11227 than the word width has undefined behavior.
11229 2012-02-19 Chong Yidong <cyd@gnu.org>
11231 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
11232 (Funhandled_file_name_directory, Ffile_name_as_directory)
11233 (Fdirectory_file_name, Fexpand_file_name)
11234 (Fsubstitute_in_file_name): Protect against invalid file handler
11235 return values (Bug#10845).

11249 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
11251 2012-02-15 Chong Yidong <cyd@gnu.org>
11253 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
11254 marked as special. Also, starting docstrings with * is obsolete.

11269 2012-02-12 Chong Yidong <cyd@gnu.org>
11271 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
11272 as that creates a dangerous corner case.
11274 * window.c (Fdelete_window_internal): Invalidate the mouse
11275 highlight (Bug#9904).
11277 2012-02-12 Glenn Morris <rgm@gnu.org>

11280 (Fx_get_selection_internal, Fx_disown_selection_internal)
11281 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
11282 * nsselect.m (Fx_own_selection_internal)
11283 (Fx_disown_selection_internal, Fx_selection_exists_p)
11284 (Fx_selection_owner_p, Fx_get_selection_internal):
11285 Sync docs and argument specs with the xselect.c versions.
11287 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>

11307 2012-02-07 Chong Yidong <cyd@gnu.org>
11309 * buffer.c (Fbuffer_local_variables)
11310 (buffer_lisp_local_variables): Handle unbound vars correctly;
11311 don't let Qunbound leak into Lisp.
11313 2012-02-07 Glenn Morris <rgm@gnu.org>
11315 * image.c (Fimagemagick_types): Doc fix.
11317 * image.c (imagemagick-render-type): Change it from a lisp object
11318 to an integer. Move the doc here from the lisp manual.

11335 2012-02-04 Eli Zaretskii <eliz@gnu.org>
11337 * w32.c (get_emacs_configuration_options):
11338 Include --enable-checking, if specified, in the return value.

11348 before BEGV. (Bug#10696)
11350 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
11352 Handle overflow when computing char display width (Bug#9496).
11353 * character.c (char_width): Return EMACS_INT, not int.
11354 (char_width, c_string_width): Check for overflow when
11355 computing the width; this is possible now that individual
11356 characters can have unbounded width. Problem introduced
11357 by merge from Emacs 23 on 2012-01-19.

11381 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
11383 (x_produce_glyphs): If the component of a composition is a null

11388 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
11389 first 2 arguments are identical. This makes inserting large
11390 output from a subprocess an order of magnitude faster on
11391 MS-Windows, where all sbrk'ed memory is always contiguous.
11393 2012-01-31 Glenn Morris <rgm@gnu.org>

11490 * xdisp.c (rows_from_pos_range): Accept additional argument
11491 DISP_STRING, and accept any glyph in a row whose object is that
11492 string as eligible for mouse highlight. Fixes mouse highlight of
11493 display strings from overlays. (Bug#10464)
11495 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
11497 emacs: fix an auto-save permissions race condition (Bug#10400)

11499 (Fmake_directory_internal): Use it.
11500 (do_auto_save_make_dir): Set it, instead of invoking chmod after

11504 (Fdo_auto_save): Catch all errors, not just file errors, so
11505 that the var is always cleared.

12010 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
12011 is set, removing the need for VIRT_ADDRESS_VARIES.
12012 (PURE_P): Use a more-efficient implementation that needs just one

12015 to 4 (xorl, subq, cmpq, setbe).
12016 * alloc.c (pure): Always extern now, since that's the

12027 (erase_phys_cursor, update_window_cursor, show_mouse_face)
12028 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
12029 behave as if the cursor position were at the window margin.
12031 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
12032 and the cursor position is out of bounds, behave as if the cursor
12033 position were at the window margin. (Bug#10075)
12035 2011-11-18 Chong Yidong <cyd@gnu.org>
12037 * window.c (Fwindow_combination_limit): Make first argument
12038 non-optional, since it is meaningless for live windows like the
12041 2011-11-18 Dmitry Antipov <dmantipov@yandex.ru>

12259 (static_offset_intervals): Remove.
12260 (offset_intervals): Rewrite using the old contents of
12261 static_offset_intervals. The old version didn't conform to C99

12499 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
12500 instead of calling the "wide" APIs directly.
12502 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
12504 * w32.h (syms_of_w32font): Add prototype.
12506 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
12508 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
12509 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
12510 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
12511 (Fmove_to_window_line): Doc fix.
12513 2011-10-27 Chong Yidong <cyd@gnu.org>
12515 * process.c (make_process): Set gnutls_state to NULL.
12517 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
12518 non-NULL, regardless of GNUTLS_INITSTAGE.
12519 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
12520 an error. Set process slots as soon as we allocate them.
12522 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
12524 2011-10-27 Chong Yidong <cyd@gnu.org>
12526 * gnutls.c (emacs_gnutls_deinit): New function.
12527 Deallocate credentials structures as well as calling gnutls_deinit.
12528 (Fgnutls_deinit, Fgnutls_boot): Use it.
12530 * process.c (make_process): Initialize GnuTLS credentials to NULL.
12531 (deactivate_process): Call emacs_gnutls_deinit.
12533 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
12535 * image.c (x_create_x_image_and_pixmap):
12536 * w32.c (sys_rename, w32_delayed_load):
12537 * w32font.c (fill_in_logfont):
12538 * w32reg.c (x_get_string_resource): Silence compiler warnings.
12540 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
12542 * w32fns.c (w32_default_color_map): New function,
12543 extracted from Fw32_default_color_map.
12544 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
12546 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
12548 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
12550 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
12552 * keyboard.c (test_undefined): New function (bug#9751).
12553 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
12555 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
12557 * sysdep.c (init_sys_modes): Fix the check for the controlling
12558 terminal (Bug#6649).
12560 2011-10-20 Eli Zaretskii <eliz@gnu.org>
12562 * dispextern.h (struct bidi_it): New member next_en_type.
12564 * bidi.c (bidi_line_init): Initialize the next_en_type member.
12565 (bidi_resolve_explicit_1): When next_en_pos is valid for the
12566 current character, check also for next_en_type being WEAK_EN.
12567 (bidi_resolve_weak): Don't enter the expensive loop if the current
12568 position is before next_en_pos. Record the bidi type of the first
12569 non-ET, non-BN character we find, in addition to its position.
12570 (bidi_level_of_next_char): Invalidate next_en_type when
12571 next_en_pos is over-stepped.
12573 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
12575 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
12576 * editfns.c: Rewrite current-time-zone so that it invokes
12577 the equivalent of (format-time-string "%Z") to get the time zone name.
12578 This fixes a bug when the time zone name contains characters that
12579 need converting from the system time locale to Emacs internal format.
12580 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
12581 that patch fixed format-time-string to do the conversion, but
12582 I forgot to fix current-time-zone.
12583 (format_time_string): New function, containing most of
12584 what Fformat_time_string used to contain.
12585 (Fformat_time_string): Rewrite in terms of format_time_string.
12586 This doesn't change this function's behavior.
12587 (current-time-zone): Rewrite to use format_time_string.
12588 This fixes the bug reported by Michael Schierl in
12589 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
12590 Jason Rumney's 2007-06-07 change worked around this bug, but
12592 * systime.h (tzname, timezone): Remove no-longer-used declarations.
12594 2011-10-19 Eli Zaretskii <eliz@gnu.org>
12596 * xdisp.c (start_display): If the character at POS is displayed
12597 via a display vector, reset IT->current.dpvec_index to zero.
12598 (try_window_reusing_current_matrix): If a line ends in a display
12599 vector or the next line starts in a display vector, continue
12600 redrawing the window even though the character position of
12601 start_row was reached.
12604 2011-10-18 Chong Yidong <cyd@gnu.org>
12606 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
12607 with nobreak-char-display too.
12609 2011-10-18 Eli Zaretskii <eliz@gnu.org>
12611 Fix part 3 of bug#9771.
12612 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
12613 (bidi_resolve_neutral): Don't enter the expensive loop looking for
12614 non-neutral characters if the current character is a paragraph
12615 separator (a.k.a. Newline). This avoids running the same
12616 expensive loop twice, once when we consume the preceding newline
12617 and the other time when the line actually needs to be displayed.
12618 Avoid the loop when we see neutrals on the base embedding level
12619 following a character whose directionality is the same as the
12620 paragraph's. This avoids running the expensive loop when a line
12621 ends in a long sequence of neutrals, like control characters.
12622 Add assertion against STRONG_AL type. Slightly rearrange code
12623 that determines the type of a neutral given the first non-neutral
12625 (bidi_level_of_next_char): Set next_en_pos to zero when
12626 invalidating its info.
12628 2011-10-17 Eli Zaretskii <eliz@gnu.org>
12630 * xdisp.c (push_display_prop): Determine whether to record string
12631 or buffer position by IT->string, not by IT->method. Allow
12632 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
12633 (move_it_vertically_backward): Don't look for character position
12634 immediately after the newline when in a continuation line.
12637 2011-10-15 Martin Rudalics <rudalics@gmx.at>
12639 * window.c (coordinates_in_window): Rewrite and delabelize
12640 vertical border check. (Bug#5357) (Bug#9618)
12642 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
12644 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
12645 errors in XSetWindowBorder (bug#9310).
12647 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
12649 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
12650 avoid crash when xmalloc overrun checking is enabled.
12652 2011-10-13 Eli Zaretskii <eliz@gnu.org>
12654 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
12655 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
12656 cursor motion with <left> and <right> arrow keys.
12658 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
12659 some callers set that themselves.
12661 2011-10-12 Eli Zaretskii <eliz@gnu.org>
12663 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
12664 display string and the previous row comes from the same string and
12665 is empty. (Bug#9739) (Bug#9738)
12667 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
12669 * doc.c (get_doc_string): Encode file name (bug#9735).
12671 2011-10-12 Eli Zaretskii <eliz@gnu.org>
12673 * bidi.c (bidi_level_of_next_char):
12674 * xdisp.c (get_visually_first_element): Remove old incorrect
12675 comments regarding the Unicode Line Separator character.
12677 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
12679 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
12681 * alloc.c (Fgc_status): Do not access beyond zombies array
12682 boundary if nzombies > MAX_ZOMBIES.
12683 * alloc.c (dump_zombies): Add missing format specifier.
12685 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
12687 * xdisp.c (set_cursor_from_row): Simplify conditionals,
12688 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
12690 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
12691 Some packages use them to denote characters with modifiers.
12693 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
12695 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
12696 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
12697 matching a pp-number. Rename parameter var to var1.
12699 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
12701 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
12703 2011-10-08 Glenn Morris <rgm@gnu.org>
12705 * callint.c (Fcall_interactively): Give a more explicit error for the
12706 'c' case with a non-character input. (Bug#8479)
12708 2011-10-08 Eli Zaretskii <eliz@gnu.org>
12710 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
12712 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
12713 lines that are hscrolled on the left.
12715 * dispnew.c (buffer_posn_from_coords): Account for a possible
12716 presence of header-line. (Bug#4426)
12718 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
12720 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
12721 Don't advertise functionality which we discourage or doesn't work.
12723 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
12725 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
12726 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
12727 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
12728 this makes Emacs dump core during garbage collection on rare
12729 occasions. sizeof is obviously inferior to offsetof here, so
12730 stick with offsetof.
12731 (GC_POINTER_ALIGNMENT): New macro.
12732 (mark_memory): Omit 3rd (offset) arg; caller changed.
12733 Don't assume EMACS_INT alignment is the same as pointer alignment.
12735 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
12737 * keyboard.c (read_key_sequence_remapped): New var.
12738 (read_key_sequence): Compute remapping in the right buffer.
12739 (command_loop_1): Use read_key_sequence's remapping directly.
12741 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
12743 * dired.c (file_name_completion): Don't expand file name.
12744 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
12745 before checking file name handler.
12747 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
12748 they've been requested explicitly (bug#9591).
12750 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
12752 * keymap.c (Fsingle_key_description): Use make_specified_string
12753 instead of build_string to build string from push_key_description.
12756 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
12758 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
12759 This fixes a Y2038 bug on 64-bit hosts.
12760 * buffer.c (reset_buffer):
12761 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
12762 (Fclear_buffer_auto_save_failure):
12763 Use 0, not -1, to represent an unset failure time, since time_t
12764 might not be signed.
12766 Remove dependency on glibc malloc internals.
12767 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12768 Move back here from lisp.h, but with their new implementations.
12769 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
12770 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
12771 * charset.c (charset_table_init): New static var.
12772 (syms_of_charset): Use it instead of xmalloc. This removes a
12773 dependency on glibc malloc internals. See Eli Zaretskii's comment in
12774 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
12775 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12776 Move back to alloc.c.
12777 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
12778 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
12780 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
12782 * nsterm.m (windowDidResize): Call x_set_window_size only when
12783 ns_in_resize is true. Otherwise set pixelwidth/height and
12784 call change_frame_size (Bug#9628).
12786 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
12788 Port --enable-checking=all to Fedora 14 x86-64.
12789 * charset.c (syms_of_charset): Also account for glibc malloc's
12790 internal overhead when calculating the initial malloc maximum.
12792 Port --enable-checking=all to Fedora 14 x86.
12793 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12795 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
12796 (overrun_check_realloc, overrun_check_free):
12797 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
12798 That way, xmalloc returns a properly-aligned pointer even if
12799 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
12800 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
12801 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
12802 into account when calculating the initial malloc maximum.
12803 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12804 Move here from alloc.c, so that charset.c can use it too.
12805 Properly align; the old code wasn't right for common 32-bit hosts
12806 when configured with --enable-checking=all.
12807 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
12808 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
12810 2011-09-29 Eli Zaretskii <eliz@gnu.org>
12812 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
12815 2011-09-28 Eli Zaretskii <eliz@gnu.org>
12817 * xdisp.c (compute_display_string_end): If there's no display
12818 string at CHARPOS, return -1.
12820 * bidi.c (bidi_fetch_char): When compute_display_string_end
12821 returns a negative value, treat the character as a normal
12822 character not covered by a display string. (Bug#9624)
12824 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
12826 * lread.c (Fread_from_string): Fix typo in docstring.
12828 2011-09-27 Eli Zaretskii <eliz@gnu.org>
12830 * xdisp.c (handle_invisible_prop): If invisible text ends on a
12831 newline, reseat the iterator instead of bidi-iterating there one
12832 character at a time. (Bug#9610)
12833 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
12834 TO_CHARPOS if the bidi iterator is at base embedding level.
12836 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
12838 * lread.c (readevalloop): Use correct code for NBSP.
12839 (read1): Likewise. (Bug#9608)
12841 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
12843 * dbusbind.c (Fdbus_register_signal): When service is not
12844 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
12846 2011-09-25 Glenn Morris <rgm@gnu.org>
12848 * buffer.c (truncate-lines): Doc fix.
12850 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
12852 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
12853 (Fset_window_next_buffers): Doc fix.
12855 2011-09-24 Glenn Morris <rgm@gnu.org>
12857 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
12859 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
12861 Fix minor problems found by static checking.
12862 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
12863 * indent.c (Fvertical_motion): Fix == vs = typo.
12865 2011-09-24 Eli Zaretskii <eliz@gnu.org>
12867 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
12868 Default value is now t. Doc fix.
12870 * indent.c (Fvertical_motion): Compute and apply the overshoot
12871 logic when moving up, not only when moving down. Fix the
12872 confusing name and values of the it_overshoot_expected variable;
12873 logic changes accordingly. (Bug#9254) (Bug#9549)
12875 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
12876 CHARPOS is covered by a display string which includes newlines.
12877 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
12878 is covered by a display string with embedded newlines.
12880 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
12882 * dbusbind.c (Fdbus_register_signal): Add match rule to
12883 Vdbus_registered_objects_table. (Bug#9581)
12884 (Fdbus_register_method, Vdbus_registered_objects_table):
12887 2011-09-24 Jim Meyering <meyering@redhat.com>
12889 do not ignore write error for any output size
12890 The previous change was incomplete.
12891 While it makes emacs --batch detect the vast majority of stdout
12892 write failures, errors were still ignored whenever the output size is
12893 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
12894 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
12895 && echo FAIL: ignored write error
12896 FAIL: ignored write error
12897 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
12898 && echo FAIL: ignored write error
12899 FAIL: ignored write error
12900 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
12902 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
12904 * emacs.c (Fkill_emacs): In noninteractive mode exit
12905 non-successfully if a write error occurred on stdout. (Bug#9574)
12907 2011-09-21 Eli Zaretskii <eliz@gnu.org>
12909 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
12912 * dispextern.h (struct it): Update the comment documenting what
12915 2011-09-20 Eli Zaretskii <eliz@gnu.org>
12917 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
12918 a display string, extend search for cursor position to end of row.
12919 (find_row_edges): If the row ends in a newline from a display
12920 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
12921 Handle the case of a display string with multiple newlines.
12922 (Fcurrent_bidi_paragraph_direction): Fix search for previous
12923 non-empty line. Fixes confusing cursor motion with arrow keys at
12924 the beginning of a line that starts with whitespace.
12926 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
12928 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
12931 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
12933 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
12934 boolean (Bug#9154).
12936 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12938 * xdisp.c (display_line): Record maximum and minimum buffer
12939 positions even if no glyphs were produced (e.g., by a zero-width
12940 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
12941 buffer positions that will be removed from the glyph row because
12943 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
12944 column is beyond frame width: don't subtract 1 "pixel" when
12945 computing width of the stretch.
12946 (reseat_at_next_visible_line_start): Undo the change made on
12947 2011-09-17 that saved paragraph information and restored it after
12948 the call to `reseat'. (Bug#9545)
12950 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12952 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
12953 and turn window cursor on if cleared (Bug#9415).
12955 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
12957 * search.c (boyer_moore): Take unibyte characters from pattern
12958 literally. (Bug#9458)
12960 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12962 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
12964 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
12966 Fix minor problem found by static checking.
12967 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
12968 initialized, to pacify gcc -Wuninitialized.
12970 * fileio.c: Report proper errno when syscall falls.
12971 (Finsert_file_contents): Save and restore errno,
12972 so that report_file_error outputs the correct diagnostic.
12973 (Fwrite_region) [CLASH_DETECTION]: Likewise.
12975 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12977 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
12979 2011-09-17 Eli Zaretskii <eliz@gnu.org>
12981 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
12982 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
12984 2011-09-17 Eli Zaretskii <eliz@gnu.org>
12986 * xdisp.c (reseat_at_next_visible_line_start): Keep information
12987 about the current paragraph and restore it after the call to reseat.
12989 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
12990 (bidi_find_paragraph_start): Search back for paragraph beginning
12991 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
12992 (bidi_move_to_visually_next): Only trigger paragraph-related
12993 computations when the last character is a newline or at EOB, not
12994 just any NEUTRAL_B. (Bug#9470)
12996 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
12997 truncated lines if point is covered by a display string. (Bug#9524)
12999 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
13001 * xselect.c: Relax test for outgoing X longs (Bug#9498).
13002 (cons_to_x_long): New function.
13003 (lisp_data_to_selection_data): Use it. Correct the test for
13004 short-versus-long data; it was negated. Break out of vector
13005 loop, for efficiency, when a long datum is discovered.
13007 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
13009 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
13011 2011-09-16 Eli Zaretskii <eliz@gnu.org>
13013 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
13014 GCC PR/17406) by declaring this function with external scope.
13016 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13018 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
13019 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
13021 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
13023 * editfns.c (Fformat): Correctly handle text properties on "%%".
13025 2011-09-15 Eli Zaretskii <eliz@gnu.org>
13027 * xterm.c (x_draw_composite_glyph_string_foreground):
13028 * w32term.c (x_draw_composite_glyph_string_foreground):
13029 * term.c (encode_terminal_code):
13030 * composite.c (composition_update_it, get_composition_id):
13031 * xdisp.c (get_next_display_element)
13032 (fill_composite_glyph_string): Add comments about special meaning
13033 of TAB characters in a composition.
13035 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13037 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
13038 This occurs when processing a multibyte format.
13039 Problem reported by Wolfgang Jenker.
13041 2011-09-15 Johan Bockgård <bojohan@gnu.org>
13043 * xdisp.c (try_cursor_movement): Only check for exact match if
13044 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
13046 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13048 Remove unused external symbols.
13049 * dispextern.h (calc_pixel_width_or_height): Remove decl.
13050 * xdisp.c (calc_pixel_width_or_height): Now static.
13051 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
13052 * indent.c (check_display_width):
13053 * w32term.c: Fix comment to match code.
13054 * xterm.c, xterm.h (x_catching_errors): Remove.
13056 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13058 * xselect.c: Use signed conversions more consistently (Bug#9498).
13059 (selection_data_to_lisp_data): Assume incoming selection data are
13060 signed integers, not unsigned. This is to be consistent with
13061 outgoing selection data, which was modified to use signed integers
13062 in as part of the fix to Bug#9196 in response to Jan D.'s comment
13063 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
13064 expects long, not unsigned long.
13066 2011-09-14 Eli Zaretskii <eliz@gnu.org>
13068 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
13069 computation of loop end. Reported by Johan Bockgård
13072 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
13074 * frame.c (Fother_visible_frames_p): Function deleted.
13076 2011-09-12 Eli Zaretskii <eliz@gnu.org>
13078 * indent.c (compute_motion): Process display vector front to back
13079 rather than the other way around. (Bug#2496)
13081 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
13083 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
13085 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
13087 * minibuf.c (Fread_from_minibuffer): Doc fix.
13089 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13091 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
13092 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
13094 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
13096 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
13097 value for non-existent files.
13099 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13101 * fileio.c (Finsert_file_contents): If the file cannot be opened,
13102 set its "size" to -1. This will set the modtime_size field of
13103 the corresponding buffer to -1, which is what
13104 verify-visited-file-modtime expects for files that do not exist.
13107 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
13109 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
13111 * lisp.h: ... from here. push_key_description is no longer
13112 defined in keyboard.c, so its declaration should not be in
13113 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
13114 logically belongs with push_key_description.
13116 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
13118 * buffer.h: Include <sys/types.h> instead of <time.h>.
13119 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
13120 Problem reported by Herbert J. Skuhra.
13122 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
13124 * xml.c (parse_region): Make the parsing work for
13125 non-comment-starting XML files again (bug#9144).
13127 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
13129 * image.c (gif_load): Fix calculation of bottom and right corner.
13132 2011-09-10 Eli Zaretskii <eliz@gnu.org>
13134 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
13135 redisplay in small windows.
13137 2011-09-09 Eli Zaretskii <eliz@gnu.org>
13139 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
13141 2011-09-08 Martin Rudalics <rudalics@gmx.at>
13143 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
13144 Operate on live windows only.
13146 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
13148 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
13150 2011-09-07 Eli Zaretskii <eliz@gnu.org>
13152 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
13153 only under bidi iteration.
13155 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
13157 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
13159 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13161 isnan: Fix porting problem to Solaris 10 with bundled gcc.
13162 Without this fix, the command to link temacs failed due to an
13163 undefined symbol __builtin_isnan. This is because
13164 /usr/include/iso/math_c99.h #defines isnan(x) to
13165 __builtin_isnan(x), but the bundled gcc, which identifies itself
13166 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
13168 * floatfns.c (isnan): #undef, and then #define to a clone of
13170 (Fisnan): Always define, since it's always available now.
13171 (syms_of_floatfns): Always define isnan at the Lisp level.
13173 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13175 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
13177 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13179 * fileio.c: Fix bugs with large file offsets (Bug#9428).
13180 The previous code assumed that file offsets (off_t values) fit in
13181 EMACS_INT variables, which is not true on typical 32-bit hosts.
13182 The code messed up by falsely reporting buffer overflow in cases
13183 such as (insert-file-contents "big" nil 1 2) into an empty buffer
13184 when "big" contains more than 2**29 bytes, even though this
13185 inserts just one byte and does not overflow the buffer.
13186 (Finsert_file_contents): Store file offsets as off_t
13187 values, not as EMACS_INT values. Check for overflow when
13188 converting between EMACS_INT and off_t. When checking for
13189 buffer overflow or for overlap, take the offsets into account.
13190 Don't use EMACS_INT for small values where int suffices.
13191 When checking for overlap, fix a typo: ZV was used where
13192 ZV_BYTE was intended.
13193 (Fwrite_region): Don't assume off_t fits into 'long'.
13194 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
13196 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
13198 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
13200 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13202 sprintf-related integer and memory overflow issues (Bug#9412).
13204 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
13205 (esprintf, exprintf, evxprintf): New functions.
13206 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
13207 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
13208 (modify_event_symbol): Do not assume that the length of
13209 name_alist_or_stem is safe to alloca and fits in int.
13210 (Fexecute_extended_command): Likewise for function name and binding.
13211 (Frecursion_depth): Wrap around reliably on integer overflow.
13212 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
13213 since some callers pass EMACS_INT values.
13214 (Fsingle_key_description): Don't crash if symbol name contains more
13215 than MAX_ALLOCA bytes.
13216 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
13217 (get_minibuffer): Arg is now EMACS_INT, not int.
13218 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
13219 (esprintf, exprintf, evxprintf): New decls.
13220 * window.h (command_loop_level, minibuf_level): Reflect API changes.
13222 * dbusbind.c (signature_cat): New function.
13223 (xd_signature, Fdbus_register_signal):
13224 Do not overrun buffer; instead, report string overflow.
13226 * dispnew.c (add_window_display_history): Don't overrun buffer.
13227 Truncate instead; this is OK since it's just a log.
13229 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
13230 even if the time zone offset is outlandishly large.
13231 Don't mishandle offset == INT_MIN.
13233 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
13234 when creating daemon; the previous buffer-overflow check was incorrect.
13236 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
13237 which has the guts of the old verror function.
13239 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
13240 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
13242 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
13243 (font_unparse_xlfd): Don't blindly alloca long strings.
13244 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
13245 fits in int, when using sprintf. Use single snprintf to count
13246 length of string rather than counting it via multiple sprintfs;
13247 that's simpler and more reliable.
13248 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
13249 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
13250 sprintf, in case result does not fit in int.
13252 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
13253 (fontset_from_font): Print it.
13255 * frame.c (tty_frame_count): Now printmax_t, not int.
13256 (make_terminal_frame, set_term_frame_name): Print it.
13257 (x_report_frame_params): In X, window IDs are unsigned long,
13258 not signed long, so print them as unsigned.
13259 (validate_x_resource_name): Check for implausibly long names,
13260 and don't assume name length fits in 'int'.
13261 (x_get_resource_string): Don't blindly alloca invocation name;
13262 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
13265 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
13266 (xg_check_special_colors, xg_set_geometry):
13267 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
13269 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
13270 Use esprintf, not sprintf, in case result does not fit in int.
13272 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13273 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
13274 it as a large positive number.
13275 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
13276 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13278 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
13279 in case result does not fit in int.
13281 * print.c (float_to_string): Detect width overflow more reliably.
13282 (print_object): Make sprintf buffer a bit bigger, to avoid potential
13283 buffer overrun. Don't assume list length fits in 'int'. Treat
13284 print length of 0 as 0, not as infinity; to be consistent with other
13285 uses of print length in this function. Don't overflow print length
13286 index. Don't assume hash table size fits in 'long', or that
13287 vectorlike size fits in 'unsigned long'.
13289 * process.c (make_process): Use printmax_t, not int, to format
13290 process-name gensyms.
13292 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
13294 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
13295 to avoid potential buffer overrun.
13297 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
13298 if X resource line is longer than 512 bytes.
13300 * xfns.c (x_window): Make sprintf buffer a bit bigger
13301 to avoid potential buffer overrun.
13303 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
13305 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
13307 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13309 Integer overflow fixes for scrolling, etc.
13310 Without these, Emacs silently mishandles large integers sometimes.
13311 For example, "C-u 4294967297 M-x recenter" was treated as if
13312 it were "C-u 1 M-x recenter" on a typical 64-bit host.
13314 * xdisp.c (try_window_id): Check Emacs fixnum range before
13315 converting to 'int'.
13317 * window.c (window_scroll_line_based, Frecenter):
13318 Check that an Emacs fixnum is in range before assigning it to 'int'.
13319 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
13320 values converted from Emacs fixnums.
13321 (Frecenter): Don't wrap around a line count if it is out of 'int'
13322 range; instead, treat it as an extreme value.
13323 (Fset_window_configuration, compare_window_configurations):
13324 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
13326 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
13327 that can exceed INT_MAX. Check that EMACS_INT value is in range
13328 before assigning it to the (possibly-narrower) index.
13329 (match_limit): Don't assume that a fixnum can fit in 'int'.
13331 * print.c (print_object): Use ptrdiff_t, not int, for index that can
13334 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
13335 (Fvertical_motion): Don't wrap around LINES values that don't fit
13336 in 'int'. Instead, treat them as extreme values. This is good
13337 enough for windows, which can't have more than INT_MAX lines anyway.
13339 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
13341 * Require libxml/parser.h to avoid compilation warning.
13343 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
13345 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
13346 since this reportedly can destroy thread storage.
13348 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
13350 * syntax.c (find_defun_start): Update all cache variables if
13351 exiting early (Bug#9401).
13353 2011-08-30 Eli Zaretskii <eliz@gnu.org>
13355 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
13357 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
13358 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
13359 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
13361 * term.c (tty_append_glyph): New function.
13362 (produce_stretch_glyph): Static function and its prototype deleted.
13364 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
13367 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
13369 * image.c (parse_image_spec): Check for nonnegative, not for positive,
13370 when checking :margin (Bug#9390).
13371 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
13372 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
13373 so that the name doesn't mislead. All uses changed.
13375 2011-08-28 Johan Bockgård <bojohan@gnu.org>
13377 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
13380 2011-08-27 Eli Zaretskii <eliz@gnu.org>
13382 * xdisp.c (move_it_to): Don't bail out early when reaching
13383 position beyond to_charpos, if we are scanning backwards.
13384 (move_it_vertically_backward): When DY == 0, make sure we get to
13385 the first character in the line after the newline.
13387 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
13389 * ccl.c: Improve and simplify overflow checking (Bug#9196).
13390 (ccl_driver): Do not generate an out-of-range pointer.
13391 (Fccl_execute_on_string): Remove unnecessary check for
13392 integer overflow, noted by Stefan Monnier in
13393 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
13394 Remove a FIXME that didn't need fixing.
13395 Simplify the newly-introduced buffer reallocation code.
13397 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
13399 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
13401 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
13403 Integer and memory overflow issues (Bug#9196).
13405 * doc.c (get_doc_string): Rework so that
13406 get_doc_string_buffer_size is the actual buffer size, rather than
13407 being 1 less than the actual buffer size; this makes xpalloc more
13410 * image.c (x_allocate_bitmap_record, cache_image):
13411 * xselect.c (Fx_register_dnd_atom):
13412 Simplify previous changes by using xpalloc.
13414 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
13415 since either will do and ptrdiff_t is convenient with xpalloc.
13417 * charset.c (charset_table_size)
13418 (struct charset_sort_data.priority): Now ptrdiff_t.
13419 (charset_compare): Don't overflow if priorities differ greatly.
13420 (Fsort_charsets): Don't assume list length fits in int.
13421 Check for size-calculation overflow when allocating sort data.
13422 (syms_of_charset): Allocate an initial charset table that is
13423 just under 64 KiB, to avoid problems with glibc malloc and mmap.
13425 * cmds.c (internal_self_insert): Check for size-calculation overflow.
13427 * composite.h (struct composition.glyph_len): Now int, not unsigned.
13428 The actual value is always <= INT_MAX, and leaving it unsigned made
13429 overflow checking harder.
13431 * dispextern.h (struct glyph_matrix.rows_allocated)
13432 (struct face_cache.size): Now ptrdiff_t, for convenience in use
13433 with xpalloc. The values are still always <= INT_MAX.
13435 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
13437 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
13438 (SAFE_NALLOCA): New macro.
13440 * region-cache.c (struct boundary.pos, find_cache_boundary)
13441 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
13442 (set_cache_region, invalidate_region_cache)
13443 (revalidate_region_cache, know_region_cache, region_cache_forward)
13444 (region_cache_backward, pp_cache):
13445 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
13446 so that ptrdiff_t * can be passed to xpalloc.
13447 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
13448 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
13449 (pp_cache): Don't assume cache_len fits in int.
13450 * region-cache.h: Adjust extern decls to match.
13452 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
13453 EMACS_INT, since either will do, for xpalloc.
13455 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
13456 (xnmalloc, xnrealloc, xpalloc): New functions.
13458 * bidi.c (bidi_shelve_header_size): New constant.
13459 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
13460 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
13462 * bidi.c (bidi_cache_shrink):
13463 * buffer.c (overlays_at, overlays_in, record_overlay_string)
13465 Don't update size of array until after memory allocation succeeds,
13466 because xmalloc/xrealloc may not return.
13467 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
13468 now that we have proper integer overflow checking.
13469 (record_overlay_string, overlay_strings): Catch overflows when
13470 calculating size of overlay_str_buf.
13472 * callproc.c (Fcall_process): Check for size overflow when
13473 calculating size of args2.
13474 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
13475 Normally we prefer signed values, but sticking with ptrdiff_t would
13476 require adding more-complicated checks.
13478 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
13479 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
13480 Redo buffer-overflow calculations to avoid integer overflow.
13481 Add a FIXME comment where memory seems to be over-allocated.
13483 * character.c (Fstring): Check for size-calculation overflow.
13485 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
13486 unnecessary integer overflow. Check for size overflow.
13487 (encode_coding_object): Don't update size until xmalloc succeeds.
13489 * composite.c (get_composition_id): Check for overflow in glyph
13490 length calculations.
13492 Integer and memory overflow fixes for display code.
13493 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
13494 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
13495 (scrolling_window): Check for overflow in size calculations.

13507 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
13508 (get_doc_string): Check for size calculation overflow.
13509 Don't update size until allocation succeeds.
13510 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
13511 EMACS_INT, where ptrdiff_t will do.
13512 (Fsubstitute_command_keys): Check for string overflow.
13514 * editfns.c (set_time_zone_rule): Don't assume environment length
13516 (message_length): Now ptrdiff_t, not int.
13517 (Fmessage_box): Don't update size until allocation succeeds.
13518 Don't assume message length fits in int.
13519 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
13521 * emacs.c (main): Do not reallocate argv, since there is a null at
13522 the end that can be overwritten, and this way there's no need to
13523 worry about size-calculation overflow.
13524 (sort_args): Check for size-calculation overflow.
13526 * eval.c (init_eval_once, grow_specpdl): Don't update size until
13528 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
13530 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
13531 (x_set_scroll_bar_width, x_figure_window_size):
13532 Check for integer overflow.
13533 (x_set_alpha): Do not assume XINT fits in int.
13535 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
13536 This is for the members text_lines, text_cols, total_lines, total_cols,
13537 where the system imposes an 'int' limit.
13539 * fringe.c (Fdefine_fringe_bitmap):
13540 Don't update size until alloc works.
13542 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
13543 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
13545 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
13546 Check for size-calculation overflow.
13547 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
13548 do, as we prefer signed integers.
13549 (id_to_widget.max_size, id_to_widget.used)
13550 (xg_store_widget_in_map, xg_remove_widget_from_map)
13551 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
13552 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
13553 Use and return ptrdiff_t, not int.
13554 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
13555 * gtkutil.h: Change prototypes to match the above.
13557 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
13558 are duplicate now that they've been promoted to lisp.h.
13559 (x_allocate_bitmap_record, x_alloc_image_color)
13560 (make_image_cache, cache_image, xpm_load):
13561 Don't update size until alloc is done.

13572 Use ptrdiff_t, not int, to count maps.
13573 (read_char_minibuf_menu_prompt): Check for overflow in size
13574 calculations. Don't update size until allocation succeeds.
13575 Redo calculations to avoid overflow.
13576 * keyboard.h: Change prototypes to match the above.
13578 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
13580 (current_minor_maps): Check for size calculation overflow.
13581 * keymap.h: Change prototypes to match the above.
13583 * lread.c (read1, init_obarray): Don't update size until alloc done.
13585 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.

13604 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
13605 for command line length. Do not attempt to address one before the
13606 beginning of an array, as that's not portable.
13608 * term.c (max_frame_lines): Remove; unused.
13609 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
13611 (encode_terminal_code, calculate_costs): Check for size
13612 calculation overflow.

13618 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
13619 subtracting pointers.
13620 (gobble_line): Check for overflow more carefully. Don't update size
13623 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
13624 Don't update size until alloc done.

13634 Use ptrdiff_t, not int, for sizes.
13635 (Finternal_make_lisp_face, cache_face):
13636 Check for size calculation overflow.
13637 (cache_face): Treat size calculation overflows as if they were
13638 memory exhaustion (the usual treatment), rather than aborting.
13640 * xfns.c (x_encode_text, x_set_name_internal)
13641 (Fx_change_window_property): Use ptrdiff_t, not int, to count
13642 sizes, since they can exceed INT_MAX in size. Check for size

13646 (xg_select): Check for size calculation overflow.
13647 Don't update size until alloc done.
13649 * xrdb.c (get_environ_db): Don't assume path length fits in int,
13650 as sprintf is limited to int lengths.
13652 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
13653 (X_LONG_MIN): New macros.
13654 Use them to make the following changes clearer.
13655 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
13656 This change doesn't affect the value now, but it may help remind
13657 future maintainers not to raise the value too much later.
13658 (SELECTION_QUANTUM): Remove, replacing with ...
13659 (selection_quantum): ... new function, which avoids overflow.
13661 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
13662 assumption that selection length fits in 'int'.
13663 (x_reply_selection_request, x_handle_selection_request)
13664 (x_get_window_property, receive_incremental_selection)
13665 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
13666 (lisp_data_to_selection_data, clean_local_selection_data):
13667 Use ptrdiff_t, not int, to record length of selection.
13668 (x_reply_selection_request, x_get_window_property)

13670 Redo calculations to avoid overflow.
13671 (x_reply_selection_request): When sending hint, ceiling it at
13672 X_LONG_MAX rather than relying on wraparound overflow to send
13674 (x_get_window_property, receive_incremental_selection)
13675 (lisp_data_to_selection_data, x_property_data_to_lisp):
13676 Check for size-calculation overflow.
13677 (x_get_window_property, receive_incremental_selection)
13678 (lisp_data_to_selection_data, Fx_register_dnd_atom):
13679 Don't store size until memory allocation succeeds.
13680 (x_get_window_property): Plug memory leak on memory exhaustion.
13681 Don't double-block input; malloc is safe here. Don't assume 2**34
13682 - 4 fits in unsigned long. Add an xassert to check
13683 XGetWindowProperty overflow. Be more careful about overflow
13684 calculations, and distinguish size from memory overflow better.
13685 (receive_incremental_selection): When tracing, don't assume
13686 unsigned int is less than INT_MAX.
13687 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
13688 harmful) conversions of unsigned short to int.
13689 (lisp_data_to_selection_data): Don't assume that integers
13690 in the range -65535 through -1 fit in an X unsigned short.
13691 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
13692 result parameters unless successful. Rely on cons_to_unsigned
13693 to report problems with elements; the old code wasn't right anyway.
13694 (x_check_property_data): Check for int overflow; we cannot use
13695 a wider type due to X limits.
13696 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
13698 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
13700 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
13701 (x_term_init): Check for size calculation overflow.
13702 (x_color_cells): Don't store size until memory allocation succeeds.
13703 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
13704 Don't assume alloca size is less than MAX_ALLOCA.
13705 (x_term_init): Don't assume length fits in int (sprintf is limited
13708 Use ptrdiff_t for composition IDs.

13728 * lisp.h (hash_lookup, hash_put):
13729 * minibuf.c (Ftest_completion):
13730 Use ptrdiff_t for hash table indexes, not int (which is too
13731 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
13732 32-bit --with-wide-int hosts).
13734 * charset.c (Fdefine_charset_internal): Check for integer overflow.
13735 Add a FIXME comment about memory leaks.
13736 (syms_of_charset): Don't assume xmalloc returns.
13738 Don't assume that stated character widths fit in int.
13739 * character.c (Fchar_width, c_string_width, lisp_string_width):
13740 * character.h (CHAR_WIDTH):
13741 * indent.c (MULTIBYTE_BYTES_WIDTH):
13742 Use sanitize_char_width to avoid undefined and/or bad behavior
13743 with outlandish widths.
13744 * character.h (sanitize_tab_width): Rename from sanitize_width,
13745 now that we have two such functions. All uses changed.
13746 (sanitize_char_width): New inline function.
13748 Don't assume that tab-width fits in int.
13749 * character.h (sanitize_width): New inline function.
13750 (SANE_TAB_WIDTH): New macro.
13751 (ASCII_CHAR_WIDTH): Use it.

13756 * fileio.c: Integer overflow issues with file modes.
13757 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
13759 * charset.c (read_hex): New arg OVERFLOW. All uses changed.

13764 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
13765 (x_send_scroll_bar_event): Likewise. Check that the size does not
13766 exceed limits imposed by XClientMessageEvent, as well as the usual
13767 ptrdiff_t and size_t limits.
13769 * keyboard.c: Overflow, signedness and related fixes.
13770 (make_lispy_movement): Use same integer type in forward decl
13771 that is used in the definition.
13772 (read_key_sequence, keyremap_step):
13773 Change bufsize argument back to int, undoing my 2011-03-30 change.
13774 We prefer signed types, and int is wide enough here.
13775 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
13776 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
13777 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
13778 length, not size_t. Use ptrdiff_t for index, not int.
13779 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
13780 possibility of integer overflow.
13782 Overflow, signedness and related fixes for images.
13784 * dispextern.h (struct it.stack[0].u.image.image_id)
13785 (struct_it.image_id, struct image.id, struct image_cache.size)

13792 * xdisp.c (calc_pixel_width_or_height):
13793 * xfns.c (image_cache_refcount):
13794 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
13795 on typical 64-bit hosts.

13803 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
13804 (lookup_image): Remove unnecessary tests.
13805 (xbm_image_p): Locals are now of int, not EMACS_INT,
13806 since parse_image_check makes sure they fit into int.
13807 (png_load, gif_load, svg_load_image):
13808 Prefer int to unsigned where either will do.
13809 (tiff_handler): New function, combining the cores of the
13810 old tiff_error_handler and tiff_warning_handler.
13811 This function is rewritten to use vsnprintf and thereby avoid
13812 stack buffer overflows. It uses only the features of vsnprintf
13813 that are common to both POSIX and native Microsoft.
13814 (tiff_error_handler, tiff_warning_handler): Use it.
13815 (tiff_load, gif_load, imagemagick_load_image):
13816 Don't assume :index value fits in 'int'.
13817 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
13818 (imagemagick_load_image): Check that crop parameters fit into
13819 the integer types that MagickCropImage accepts. Don't assume
13820 Vimagemagick_render_type has a nonnegative value. Don't assume
13821 size_t fits in 'long'.
13822 (gs_load): Use printmax_t to print the widest integers possible.
13823 Check for integer overflow when computing image height and width.
13825 2011-08-26 Eli Zaretskii <eliz@gnu.org>

13836 (handle_single_display_spec): If the display spec is of the form
13837 `(space ...)', and specifies display in the text area, return 2
13839 (try_cursor_movement): Check for the need to scroll more
13840 accurately, and prefer exact match for point under bidi.
13841 Don't advance `row' beyond the last row of the window.

13862 positioning on the newline at EOL of R2L text within L2R
13863 paragraph, and vice versa.
13864 (try_cursor_movement): Check continued rows, in addition to
13865 continuation rows. Fixes unwarranted scroll when point enters a
13866 continued line of R2L text within an L2R paragraph, or vice versa.

13894 * xdisp.c (redisplay_window): When computing centering_position,
13895 account for the height of the header line. (Bug#8874)
13897 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
13898 instead of CHAR_TO_BYTE. Fixes a crash when a completion
13899 candidate is selected by the mouse, and that candidate has a
13900 composed character under the mouse.
13902 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
13903 coordinates reported by pos-visible-in-window-p for a composed
13904 character in column zero.
13906 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

13913 consider it a hit if to_charpos is anywhere in the range of the
13914 composed buffer positions.
13916 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
13918 * image.c (gif_load): Don't assume that each subimage has the same
13919 dimensions as the base image. Handle disposal method that is
13920 "undefined" by the gif spec (Bug#9335).
13922 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
13924 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

13930 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
13931 from an Org mode buffer to a Speedbar frame.
13933 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
13934 a composition, take its buffer position from IT->cmp_it.charpos.
13935 Fixes cursor positioning at the beginning of a line that begins
13936 with a composed character.
13938 2011-08-18 Eli Zaretskii <eliz@gnu.org>
13940 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
13941 character bidirectional type, use STRONG_L instead. Fixes crashes
13942 in a buffer produced by `describe-categories'.
13944 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
13945 members before the level stack, so they would be saved and
13946 restored when copying iterator state. Fixes incorrect reordering
13947 around TABs covered by display properties.

14037 * nsterm.m (sendEvent): If event is NSApplicationDefined and
14038 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
14039 the event loop (Bug#7276).

14081 entry. Force push_it to save on the stack the current
14082 buffer/string position, to be restored by pop_it. Fix flags in
14083 the iterator structure wrt the object coming from a display
14084 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
14085 properties. (Bug#9284)

14305 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
14306 In other words, assume that every image size is allowed, on non-X
14307 hosts. This assumption is probably wrong, but it lets Emacs compile.
14309 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
14311 * regex.c (re_iswctype): Convert return values to boolean.
14313 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
14315 * xdisp.c (compute_display_string_pos): Don't use cached display
14316 string position if the buffer had its restriction changed.
14319 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14321 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
14323 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14325 Integer signedness and overflow and related fixes. (Bug#9079)
14327 * bidi.c: Integer size and overflow fixes.
14328 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
14329 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
14330 (bidi_cache_find_level_change, bidi_cache_ensure_space)
14331 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
14332 (bidi_find_other_level_edge):
14333 Use ptrdiff_t instead of EMACS_INT where either will do.
14334 This works better on 32-bit hosts configured --with-wide-int.
14335 (bidi_cache_ensure_space): Check for size-calculation overflow.
14336 Use % rather than repeated addition, for better worst-case speed.
14337 Don't set bidi_cache_size until after xrealloc returns, because it
14339 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
14340 (bidi_cache_ensure_space): Also check that the bidi cache size
14341 does not exceed that of the largest Lisp string or buffer. See Eli
14342 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
14344 * alloc.c (__malloc_size_t): Remove.
14345 All uses replaced by size_t. See Andreas Schwab's note
14346 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
14348 * image.c: Improve checking for integer overflow.
14349 (check_image_size): Assume that f is nonnull, since
14350 it is always nonnull in practice. This is one less thing to
14351 worry about when checking for integer overflow later.
14352 (x_check_image_size): New function, which checks for integer
14353 overflow issues inside X.
14354 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
14355 This removes the need for a memory_full check.
14356 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
14357 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
14358 (xbm_read_bitmap_data): Change locals back to 'int', since
14359 their values must fit in 'int'.
14360 (xpm_load_image, png_load, tiff_load):
14361 Invoke x_create_x_image_and_pixmap earlier,
14362 to avoid much needless work if the image is too large.
14363 (tiff_load): Treat overly large images as if
14364 x_create_x_image_and_pixmap failed, not as malloc failures.
14365 (gs_load): Use x_check_image_size.
14367 * gtkutil.c: Omit integer casts.
14368 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
14369 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
14371 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
14373 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
14374 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
14375 would wrongly return t on a 64-bit host.
14377 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
14378 The plain *_OVERFLOW macros run afoul of GCC bug 49705
14379 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
14380 and therefore cause GCC to emit a bogus diagnostic in some cases.
14382 * image.c: Integer signedness and overflow and related fixes.
14383 This is not an exhaustive set of fixes, but it's time to
14384 record what I've got.
14385 (lookup_pixel_color, check_image_size): Remove redundant decls.
14386 (check_image_size): Don't assume that arbitrary EMACS_INT values
14387 fit in 'int', or that arbitrary 'double' values fit in 'int'.
14388 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
14389 (tiff_load, imagemagick_load_image):
14390 Check for overflow in size calculations.
14391 (x_create_x_image_and_pixmap): Remove unnecessary test for
14392 xmalloc returning NULL; that can't happen.
14393 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
14394 (xpm_color_bucket): Use better integer hashing function.
14395 (xpm_cache_color): Don't possibly over-allocate memory.
14396 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
14397 (gif_memory_source):
14398 Use ptrdiff_t, not int or size_t, to record sizes.
14399 (png_load): Don't assume values greater than 2**31 fit in 'int'.
14400 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
14401 either works, as we prefer signed integers.
14402 (tiff_read_from_memory, tiff_write_from_memory):
14403 Return tsize_t, not size_t, since that's what the TIFF API wants.
14404 (tiff_read_from_memory): Don't fail simply because the read would
14405 go past EOF; instead, return a short read.
14406 (tiff_load): Omit no-longer-needed casts.
14407 (Fimagemagick_types): Don't assume size fits into 'int'.
14409 Improve hashing quality when configured --with-wide-int.
14410 * fns.c (hash_string): New function, taken from sxhash_string.
14411 Do not discard information about ASCII character case; this
14412 discarding is no longer needed.
14413 (sxhash-string): Use it. Change sig to match it. Caller changed.
14414 * lisp.h: Declare it.
14415 * lread.c (hash_string): Remove, since we now use fns.c's version.
14416 The fns.c version returns a wider integer if --with-wide-int is
14417 specified, so this should help the quality of the hashing a bit.
14419 * emacs.c: Integer overflow minor fix.
14420 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
14421 Define only if GNU_LINUX.
14422 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
14424 * dispnew.c: Integer signedness and overflow fixes.
14425 Remove unnecessary forward decls, that were a maintenance hassle.
14426 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
14428 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
14429 (scrolling_window): Use ptrdiff_t, not int, for byte count.
14430 (prepare_desired_row, line_draw_cost):
14431 Use int, not unsigned, where either works.
14432 (save_current_matrix, restore_current_matrix):
14433 Use ptrdiff_t, not size_t, where either works.
14434 (init_display): Check for overflow more accurately, and without
14435 relying on undefined behavior.
14437 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
14438 Remove, replacing with the new symbols in lisp.h. All uses changed.
14439 * fileio.c (make_temp_name):
14440 * filelock.c (lock_file_1, lock_file):
14441 * xdisp.c (message_dolog):
14442 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
14443 Use pMd etc. instead.
14444 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
14445 replacing the pWIDE etc. symbols removed from editfns.c.
14447 * keyboard.h (num_input_events): Now uintmax_t.
14448 This is (very slightly) less likely to mess up due to wraparound.
14451 * buffer.c: Integer signedness fixes.
14452 (alloc_buffer_text, enlarge_buffer_text):
14453 Use ptrdiff_t rather than size_t when either will do, as we prefer
14456 * alloc.c: Integer signedness and overflow fixes.
14457 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
14458 (__malloc_size_t): Default to size_t, not to int.
14459 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
14460 (Fgarbage_collect, mark_object_loop_halt, mark_object):
14461 Prefer ptrdiff_t to size_t when either would do, as we prefer
14463 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
14464 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
14465 Now const. Initialize with values that are in range even if char
14467 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
14468 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
14469 These functions do the right thing with sizes > 2**32.
14470 (check_depth): Now ptrdiff_t, not int.
14471 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
14472 Adjust to new way of storing sizes. Check for size overflow bugs
14474 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
14475 slightly wrong anyway, as it missed one instance of
14476 XMALLOC_OVERRUN_CHECK_OVERHEAD.
14477 (refill_memory_reserve): Omit needless cast to size_t.
14478 (mark_object_loop_halt): Mark as externally visible.
14480 * xselect.c: Integer signedness and overflow fixes.
14481 (Fx_register_dnd_atom, x_handle_dnd_message):
14482 Use ptrdiff_t, not size_t, since we prefer signed.
14483 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
14484 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
14485 x_dnd_atoms_size and x_dnd_atoms_length.
14487 * doprnt.c: Prefer signed to unsigned when either works.
14489 * doprnt.c (doprnt):
14491 * xdisp.c (vmessage):
14492 Use ptrdiff_t, not size_t, when using or implementing doprnt,
14493 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
14494 prefer signed arithmetic to avoid comparison confusion.
14495 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
14496 but is a bit tricky.
14498 Assume freestanding C89 headers, string.h, stdlib.h.
14499 * data.c, doprnt.c, floatfns.c, print.c:
14500 Include float.h unconditionally.
14501 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
14502 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
14503 * regex.c: Likewise for stddef.h, string.h.
14504 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
14505 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
14506 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
14507 (STDC_HEADERS): Remove obsolete defines.
14508 * sysdep.c: Include limits.h unconditionally.
14510 Assume support for memcmp, memcpy, memmove, memset.
14511 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
14512 * regex.c (memcmp, memcpy):
14513 Remove; we assume C89 now.
14515 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
14516 (__malloc_safe_bcopy): Remove; no longer needed.
14518 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
14519 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
14520 well either way, and we prefer signed to unsigned.
14522 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
14524 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
14525 closes the connection while we're reading (bug#9182).
14527 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
14529 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
14530 are specified (Bug#9168).
14532 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
14534 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
14535 Found by GCC static checking and --with-wide-int on a 32-bit host.
14537 2011-07-25 Eli Zaretskii <eliz@gnu.org>
14539 * xdisp.c (compute_display_string_pos): Fix logic of caching
14540 previous display string position. Initialize cached_prev_pos to
14541 -1. Fixes slow-down at the beginning of a buffer.
14543 2011-07-24 Eli Zaretskii <eliz@gnu.org>
14545 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
14546 for attrs[LFACE_FONTSET_INDEX].
14548 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
14550 * xml.c (parse_region): Remove unused local
14551 that was recently introduced.
14553 2011-07-23 Eli Zaretskii <eliz@gnu.org>
14555 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
14556 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
14558 * xdisp.c (move_it_in_display_line_to): Record the best matching
14559 position for TO_CHARPOS while scanning the line, and restore it on
14560 exit if none of the characters scanned was an exact match.
14561 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
14562 when exact match is impossible due to invisible text, and the
14563 lines are truncated.
14565 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
14567 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
14570 2011-07-22 Eli Zaretskii <eliz@gnu.org>
14572 Fix a significant slow-down of cursor motion with C-n, C-p,
14573 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
14574 auto-repeat under bidi redisplay in fontified buffers.
14575 * xdisp.c (compute_stop_pos_backwards): New function.
14576 (next_element_from_buffer): Call compute_stop_pos_backwards to
14577 find a suitable prev_stop when we find ourselves before
14579 (reseat): Don't look for prev_stop, as that could mean a very long
14581 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
14582 <cached_disp_overlay_modiff>: Cache for last found display string
14584 (compute_display_string_pos): Return the cached position if asked
14585 about the same buffer in the same area of character positions, and
14586 the buffer wasn't changed since the time the display string
14587 position was cached.
14589 2011-07-22 Eli Zaretskii <eliz@gnu.org>
14591 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
14592 is an integer, which is important for empty lines. (Bug#9149)
14594 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
14596 * frame.c (Fmodify_frame_parameters): In tty case, update the
14597 default face if necessary (Bug#4238).
14599 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
14601 * editfns.c (Fstring_to_char): No need to explain what a character
14602 is in the docstring (Bug#6576).
14604 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
14606 * xml.c (parse_region): Make sure we always return a tree.
14608 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
14610 * xml.c (parse_region): If a document contains only comments,
14613 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
14615 * xml.c (make_dom): Return comments, too.
14617 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
14620 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
14621 and the surrounding thread.
14622 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
14623 rather than fgets, and retry after EINTR. Otherwise, 'emacs
14624 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
14626 * s/openbsd.h (BROKEN_SIGIO): Define.
14627 * unexelf.c (unexec) [__OpenBSD__]:
14628 Don't update the .mdebug section of the Alpha COFF symbol table.
14630 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14632 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
14635 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
14637 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
14638 This fixes some race conditions on the permissions of any newly
14641 * alloc.c (valid_pointer_p): Use pipe, not open.
14642 This fixes some permissions issues when debugging.
14644 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
14645 If fchown fails to set both uid and gid, try to set just gid,
14646 as that is sometimes allowed. Adjust the file's mode to eliminate
14647 setuid or setgid bits that are inappropriate if fchown fails.
14649 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
14651 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
14652 to compare Lisp_Objects.
14653 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
14654 global_gnutls_log_level, don't mistake it for a Lisp_Object.
14655 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
14657 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
14659 * lread.c (read_integer): Unread even EOF character.
14660 (read1): Likewise. Properly record start position of symbol.
14662 * lread.c (read1): Read `#:' as empty uninterned symbol if no
14663 symbol character follows.
14665 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
14667 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
14668 This works around a problem with the previous change to Fcopy_file.
14669 Recent glibc declares fchown with __attribute__((warn_unused_result)),
14670 and without this change, GCC might complain about discarding
14671 fchown's return value.
14673 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
14675 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
14677 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
14679 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
14681 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
14683 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
14684 it's used from the C level.
14686 * process.c: Use the same condition for POLL_FOR_INPUT in both
14687 keyboard.c and process.c (bug#1858).
14689 2011-07-09 Lawrence Mitchell <wence@gmx.li>
14691 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
14692 (Fgnutls_boot): Use it.
14694 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
14696 * doc.c (Fsubstitute_command_keys): Revert last change.
14698 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
14700 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
14701 quotes the next character, and doesn't affect other longer
14702 sequences (bug#8935).
14704 * lread.c (syms_of_lread): Clarify that is isn't only
14705 `eval-buffer' and `eval-defun' that's affected by
14706 `lexical-binding' (bug#8460).
14708 2011-07-15 Eli Zaretskii <eliz@gnu.org>
14710 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
14711 bidi redisplay when a line includes both an image and is truncated.
14713 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
14715 Fix minor problems found by static checking.
14716 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
14717 (elsz): Now a signed constant, not a size_t var. We prefer signed
14718 types to unsigned, to avoid integer comparison confusion. Without
14719 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
14720 "cannot optimize loop, the loop counter may overflow", a symptom
14722 * indent.c (Fvertical_motion): Mark locals as initialized.
14723 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
14725 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
14727 * search.c (Fre_search_backward): Mention `case-fold-search' in
14728 all the re_search_* functions (bug#8138).
14730 * keyboard.c (Fopen_dribble_file): Document when the file is
14733 2011-07-14 Eli Zaretskii <eliz@gnu.org>
14735 * bidi.c (bidi_dump_cached_states): Fix format of displaying
14738 Support bidi reordering of display and overlay strings.
14739 * xdisp.c (compute_display_string_pos)
14740 (compute_display_string_end): Accept additional argument STRING.
14741 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
14742 (reseat_to_string): Initialize bidi_it->string.s and
14743 bidi_it->string.schars.
14744 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
14745 NULL (avoids a crash in bidi_paragraph_init).
14746 Initialize itb.string.lstring.

15247 (clone_per_buffer_values): Don't assume that

15249 This isn't true in general, and it's particularly not true
15250 if Emacs is configured with --with-wide-int.
15251 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
15252 New macros, used in the buffer.c change.

15288 Random fixes. E.g., (random) never returned negative values.
15289 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
15290 subseconds part to the entropy, as that's a bit more random.
15291 Prefer signed to unsigned, since the signedness doesn't matter and
15292 in general we prefer signed. When given a limit, use a
15293 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
15294 latter isn't right if USE_2_TAGS_FOR_INTS.
15295 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
15296 not 0..VALMASK. Don't discard "excess" bits that random () returns.
15298 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
15300 * textprop.c (text_property_stickiness):
15301 Obey Vtext_property_default_nonsticky.

15308 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
15309 This is more efficient than Ffile_directory_p and avoids a minor race.
15311 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
15313 * buffer.c (Foverlay_put): Say what the return value is
15316 * fileio.c (barf_or_query_if_file_exists): Check first if the file
15317 is a directory before asking whether to use the file name
15319 (barf_or_query_if_file_exists): Make the "File is a directory"
15320 error be more correct.
15322 * fns.c (Frequire): Remove the mention of the .gz files, since
15323 that's installation-specific, but keep the mention of
15324 `get-load-suffixes'.
15326 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
15328 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

15334 (syms_of_gnutls): Remove duplicate DEFSYM for
15335 Qgnutls_bootprop_verify_hostname_error, an error for
15336 Qgnutls_bootprop_verify_error (which is no longer used).
15338 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
15339 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
15340 Also (re)move comments that are misplaced or no longer relevant.
15342 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15344 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).
15346 2011-07-03 Chong Yidong <cyd@stupidchicken.com>
15348 * xfaces.c (Finternal_merge_in_global_face): Modify the foreground

15403 (syms_of_keymap): Defsubr make-composed-keymap.
15404 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

15441 * eval.c (struct backtrace): Simplify and port the data structure.
15442 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
15443 signed bit field, as this assumption is not portable and it makes
15444 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
15445 "char debug_on_exit : 1" as this is not portable either; instead,
15446 use the portable "unsigned int debug_on_exit : 1". Remove unused
15447 member evalargs. Remove obsolete comments about cc bombing out.
15449 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

15624 * keyboard.h (struct keyboard.kbd_macro_bufsize):
15625 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
15626 Use ptrdiff_t, not int, for sizes.
15627 Don't increment bufsize until after realloc succeeds.
15628 Check for size-calculation overflow.
15629 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
15631 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
15633 * lread.c: Integer overflow fixes.
15634 (read_integer): Radix is now EMACS_INT, not int,
15635 to improve quality of diagnostics for out-of-range radices.
15636 Calculate buffer size correctly for out-of-range radices.
15637 (read1): Check for integer overflow in radices, and in
15638 read-circle numbers.
15639 (read_escape): Avoid int overflow.
15640 (Fload, openp, read_buffer_size, read1)
15641 (substitute_object_recurse, read_vector, read_list, map_obarray):
15642 Use ptrdiff_t, not int, for sizes.
15643 (read1): Use EMACS_INT, not int, for sizes.
15644 Check for size overflow.
15646 * image.c (cache_image): Check for size arithmetic overflow.
15648 * lread.c: Integer overflow issues.
15649 (saved_doc_string_size, saved_doc_string_length)

15655 (read_escape): Check for hex character overflow.
15657 2011-06-22 Leo Liu <sdl.web@gmail.com>
15659 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
15660 Move to minibuffer.el.
15662 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
15664 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
15665 The following patches are for when GLYPH_DEBUG && !XASSERT.
15666 * dispextern.h (trace_redisplay_p, dump_glyph_string):
15667 * dispnew.c (flush_stdout):
15668 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
15669 Mark as externally visible.
15670 * dispnew.c (check_window_matrix_pointers): Now static.
15671 * dispnew.c (window_to_frame_vpos):
15672 * xfns.c (unwind_create_frame):
15673 * xterm.c (x_check_font): Remove unused local.
15674 * scroll.c (CHECK_BOUNDS):
15675 * xfaces.c (cache_fache): Rename local to avoid shadowing.
15676 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
15677 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
15678 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
15679 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
15681 (debug_method_add): Use va_list and vsprintf rather than relying
15682 on undefined behavior with wrong number of arguments.
15683 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
15684 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
15685 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
15686 since we're not interested in debugging glyphs with old libraries.
15687 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
15688 GCC 4.6.0's static checking.
15690 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
15692 Integer overflow and signedness fixes (Bug#8873).

15701 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
15702 (x_create_bitmap_from_xpm_data):
15703 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
15704 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
15706 * xfaces.c (load_pixmap):
15707 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
15708 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
15709 (.bitmaps_last, struct x_output.icon_bitmap):
15710 Use ptrdiff_t, not int, for bitmap indexes.
15711 (x_allocate_bitmap_record): Check for size overflow.
15712 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
15714 Use ptrdiff_t, not int, for overlay counts.
15715 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
15716 * editfns.c (overlays_around, get_pos_property):
15717 * textprop.c (get_char_property_and_overlay):
15718 * xdisp.c (next_overlay_change, note_mouse_highlight):
15719 * xfaces.c (face_at_buffer_position):
15720 * buffer.c (OVERLAY_COUNT_MAX): New macro.
15721 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
15722 (Fnext_overlay_change, Fprevious_overlay_change)
15723 (mouse_face_overlay_overlaps, Foverlays_in):
15724 Use ptrdiff_t, not int, for sizes.
15725 (overlays_at, overlays_in): Check for size-calculation overflow.
15727 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
15729 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
15730 (x_session_initialize): Do not assume string length fits in int.
15732 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
15733 This is unlikely, but can occur if DPI is outlandish.
15735 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
15736 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
15738 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
15739 * xrdb.c (magic_file_p, search_magic_path):
15740 Omit last arg SUFFIX; it was always 0. All callers changed.
15741 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
15743 * xfont.c (xfont_match): Avoid need for strlen.
15745 * xfns.c: Don't assume strlen fits in int.
15746 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
15748 * xdisp.c (message_log_check_duplicate): Return intmax_t,
15749 not unsigned long, as we prefer signed integers. All callers changed.
15750 Detect integer overflow in repeat count.
15751 (message_dolog): Don't assume print length fits in 39 bytes.
15752 (display_mode_element): Don't assume strlen fits in int.
15754 * termcap.c: Don't assume sizes fit in int and never overflow.
15755 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
15756 (gobble_line): Check for size-calculation overflow.
15758 * minibuf.c (Fread_buffer):
15759 * lread.c (intern, intern_c_string):
15760 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
15761 Don't assume string length fits in int.
15763 * keyboard.c (parse_tool_bar_item):
15764 * gtkutil.c (style_changed_cb): Avoid need for strlen.
15766 * font.c: Don't assume string length fits in int.
15767 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
15768 Use ptrdiff_t, not int.
15769 (font_intern_prop): Don't assume string length fits in int.
15770 Don't assume integer property fits in fixnum.
15771 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
15773 * filelock.c: Fix some buffer overrun and integer overflow issues.
15774 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
15775 Reformulate so as not to need the command string.
15776 Invoke gzip -cd rather than gunzip, as it's more portable.
15777 (lock_info_type, lock_file_1, lock_file):
15778 Don't assume pid_t and time_t fit in unsigned long.
15779 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
15780 (current_lock_owner): Prefer signed type for sizes.
15781 Use memcpy, not strncpy, where memcpy is what is really wanted.
15782 Don't assume (via atoi) that time_t and pid_t fit in int.
15783 Check for time_t and/or pid_t out of range, e.g., via a network share.
15784 Don't alloca where an auto var works fine.
15786 * fileio.c: Fix some integer overflow issues.
15787 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
15788 Don't assume string length fits in int.
15789 (directory_file_name): Don't assume string length fits in long.
15790 (make_temp_name): Don't assume pid fits in int, or that its print
15791 length is less than 20.
15793 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
15795 * coding.c (make_subsidiaries): Don't assume string length fits in int.
15797 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
15799 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
15800 We prefer signed integers, even for size calculations.
15802 * emacs.c: Don't assume string length fits in 'int'.
15803 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
15804 (main): Don't invoke strlen when not needed.
15806 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
15807 (XD_DEBUG_MESSAGE): Don't waste a byte.
15809 * callproc.c (getenv_internal_1, getenv_internal)
15810 (Fgetenv_internal):
15811 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
15813 * lread.c (invalid_syntax): Omit length argument.
15814 All uses changed. This doesn't fix a bug, but it simplifies the
15815 code away from its former Hollerith-constant appearance, and it's
15816 one less 'int' to worry about when looking at integer-overflow issues.
15817 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
15819 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
15820 This didn't break anything, but it didn't help either.
15821 It's confusing to put a bogus integer in a place where the actual
15822 value does not matter.
15823 (LIST_END_P): Remove unused macro and its bogus comment.
15824 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
15826 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
15827 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
15829 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
15830 We prefer signed types, and the value cannot exceed the EMACS_INT
15831 range anyway (because otherwise the length would not be representable).
15832 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
15833 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
15834 This avoids a GCC warning when WIDE_EMACS_INT.
15836 * indent.c (sane_tab_width): New function.
15837 (current_column, scan_for_column, Findent_to, position_indentation)
15838 (compute_motion): Use it. This is just for clarity.
15839 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
15841 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
15843 * lisp.h (lint_assume): New macro.
15844 * composite.c (composition_gstring_put_cache):
15845 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
15847 * editfns.c, insdel.c:
15848 Omit unnecessary forward decls, to simplify future changes.
15850 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
15852 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
15854 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
15855 Use much-faster test for byte-length change.
15856 Don't assume string byte-length fits in 'int'.
15857 Check that character arg fits in 'int'.
15858 (mapcar1): Declare byte as byte, for clarity.
15860 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
15862 * fns.c (concat): Catch string overflow earlier.
15863 Do not rely on integer wraparound.
15865 * dispextern.h (struct it.overlay_strings_charpos)
15866 (struct it.selective): Now EMACS_INT, not int.
15867 * xdisp.c (forward_to_next_line_start)
15868 (back_to_previous_visible_line_start)
15869 (reseat_at_next_visible_line_start, next_element_from_buffer):
15870 Don't arbitrarily truncate the value of 'selective' to int.
15872 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
15874 * composite.c: Don't truncate sizes to 'int'.
15875 (composition_gstring_p, composition_reseat_it)
15876 (composition_adjust_point): Use EMACS_INT, not int.
15877 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
15878 not EMACS_UINT, for indexes.
15880 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
15882 * buffer.c: Include <verify.h>.
15883 (struct sortvec.priority, struct sortstr.priority):
15884 Now EMACS_INT, not int.
15885 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
15886 (struct sortstr.size, record_overlay_string)
15887 (struct sortstrlist.size, struct sortlist.used):
15888 Don't truncate size to int.
15889 (record_overlay_string): Check for size-calculation overflow.
15890 (init_buffer_once): Check at compile-time, not run-time.
15892 2011-06-22 Jim Meyering <meyering@redhat.com>
15894 Don't leak an XBM-image-sized buffer
15895 * image.c (xbm_load): Free the image buffer after using it.
15897 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
15900 * composite.c (find_automatic_composition): Omit needless 'return 0;'
15901 that Sun C diagnosed.
15902 * fns.c (secure_hash): Fix pointer signedness issue.
15903 * intervals.c (static_offset_intervals): New function.
15904 (offset_intervals): Use it.
15906 2011-06-21 Leo Liu <sdl.web@gmail.com>
15909 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
15912 * fns.c (secure_hash): Rename from crypto_hash_function and change
15913 the first arg to accept symbols.
15914 (Fsecure_hash): New primitive.
15915 (syms_of_fns): New symbols.
15917 2011-06-20 Deniz Dogan <deniz@dogan.se>
15919 * process.c (Fset_process_buffer): Clarify return value in
15922 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
15924 * dispnew.c (add_window_display_history): Use BVAR.
15926 * xdisp.c (debug_method_add): Use BVAR.
15927 (check_window_end, dump_glyph_matrix, dump_glyph)
15928 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
15930 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
15933 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
15934 check till after the cache is created in init_frame_faces.
15936 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
15938 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
15940 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
15942 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
15943 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
15944 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
15946 Improve buffer-overflow checking (Bug#8873).
15947 * fileio.c (Finsert_file_contents):
15948 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
15949 Remove the old (too-loose) buffer overflow checks.
15950 They weren't needed, since make_gap checks for buffer overflow.
15951 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
15952 The old code merely checked for Emacs fixnum overflow, and relied
15953 on undefined (wraparound) behavior. The new code avoids undefined
15954 behavior, and also checks for ptrdiff_t and/or size_t overflow.
15956 * editfns.c (Finsert_char): Don't dump core with very negative counts.
15957 Tune. Don't use wider integers than needed. Don't use alloca.
15958 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
15960 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
15962 * insdel.c, lisp.h (buffer_overflow): New function.
15963 (insert_from_buffer_1, replace_range, replace_range_2):
15964 * insdel.c (make_gap_larger):
15965 * editfns.c (Finsert_char):
15966 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
15968 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
15970 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
15972 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
15974 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
15975 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
15977 * fileio.c: Don't assume EMACS_INT fits in off_t.
15978 (emacs_lseek): New static function.
15979 (Finsert_file_contents, Fwrite_region): Use it.
15980 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
15982 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
15984 * fns.c: Don't overflow int when computing a list length.
15985 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
15986 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
15987 truncation on 64-bit hosts. Check for QUIT every
15988 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
15989 faster and is responsive enough.
15990 (Flength): Report an error instead of overflowing an integer.
15991 (Fsafe_length): Return a float if the value is not representable
15992 as a fixnum. This shouldn't happen except in contrived situations.
15993 (Fnthcdr, Fsort): Don't assume list length fits in int.
15994 (Fcopy_sequence): Don't assume vector length fits in int.
15996 * alloc.c: Check that resized vectors' lengths fit in fixnums.
15997 (header_size, word_size): New constants.
15998 (allocate_vectorlike): Don't check size overflow here.
15999 (allocate_vector): Check it here instead, since this is the only
16000 caller of allocate_vectorlike that could cause overflow.
16001 Check that the new vector's length is representable as a fixnum.
16003 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
16004 The previous code was bogus. For example, next_almost_prime (32)
16005 returned 39, which is undesirable as it is a multiple of 3; and
16006 next_almost_prime (24) returned 25, which is a multiple of 5 so
16007 why was the code bothering to check for multiples of 7?
16009 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
16011 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
16013 Variadic C functions now count arguments with ptrdiff_t.
16014 This partly undoes my 2011-03-30 change, which replaced int with size_t.
16015 Back then I didn't know that the Emacs coding style prefers signed int.
16016 Also, in the meantime I found a few more instances where arguments
16017 were being counted with int, which may truncate counts on 64-bit
16018 machines, or EMACS_INT, which may be unnecessarily wide.
16019 * lisp.h (struct Lisp_Subr.function.aMANY)
16020 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
16021 Arg counts are now ptrdiff_t, not size_t.
16022 All variadic functions and their callers changed accordingly.
16023 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
16024 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
16025 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
16026 * callint.c (Fcall_interactively): Check arg count for overflow,
16027 to avoid potential buffer overrun. Use signed char, not 'int',
16028 for 'varies' array, so that we needn't bother to check its size
16029 calculation for overflow.
16030 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
16031 * eval.c (apply_lambda):
16032 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
16033 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
16034 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
16036 * callint.c (Fcall_interactively): Don't use index var as event count.
16038 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
16039 * mem-limits.h (SIZE): Remove; no longer used.
16041 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
16043 Remove unnecessary casts.
16044 * xterm.c (x_term_init):
16045 * xfns.c (x_set_border_pixel):
16046 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
16047 These aren't needed now that we assume ANSI C.
16049 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
16050 It's more likely to cause problems (due to unsigned overflow)
16053 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
16055 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
16057 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
16059 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
16061 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
16063 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
16065 GLYPH_CODE_FACE returns EMACS_INT, not int.
16066 * dispextern.h (merge_faces):
16067 * xfaces.c (merge_faces):
16068 * xdisp.c (get_next_display_element, next_element_from_display_vector):
16069 Don't assume EMACS_INT fits in int.
16071 * character.h (CHAR_VALID_P): Remove unused parameter.
16072 * fontset.c, lisp.h, xdisp.c: All uses changed.
16074 * editfns.c (Ftranslate_region_internal): Omit redundant test.
16076 * fns.c (concat): Minor tuning based on overflow analysis.
16077 This doesn't fix any bugs. Use int to hold character, instead
16078 of constantly refetching from Emacs object. Use XFASTINT, not
16079 XINT, for value known to be a character. Don't bother comparing
16080 a single byte to 0400, as it's always less.
16082 * floatfns.c (Fexpt):
16083 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
16085 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
16088 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
16090 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
16091 Without this fix, on a 64-bit host (aset S 0 4294967386) would
16092 incorrectly succeed when S was a string, because 4294967386 was
16093 truncated before it was used.
16095 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
16096 Otherwise, an out-of-range integer could cause undefined behavior
16099 * composite.c: Use int, not EMACS_INT, for characters.
16100 (fill_gstring_body, composition_compute_stop_pos): Use int, not
16101 EMACS_INT, for values that are known to be in character range.
16102 This doesn't fix any bugs but is the usual style inside Emacs and
16103 may generate better code on 32-bit machines.
16105 Make sure a 64-bit char is never passed to ENCODE_CHAR.
16106 This is for reasons similar to the recent CHAR_STRING fix.
16107 * charset.c (Fencode_char): Check that character arg is actually
16108 a character. Pass an int to ENCODE_CHAR.
16109 * charset.h (ENCODE_CHAR): Verify that the character argument is no
16110 wider than 'int', as a compile-time check to prevent future regressions
16113 * character.c (char_string): Remove unnecessary casts.
16115 Make sure a 64-bit char is never passed to CHAR_STRING.
16116 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
16117 by silently ignoring the top 32 bits, allowing some values
16118 that were far too large to be valid characters.
16119 * character.h: Include <verify.h>.
16120 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
16121 arguments are no wider than unsigned, as a compile-time check
16122 to prevent future regressions in this area.
16124 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
16125 (Fsubst_char_in_region):
16127 * xdisp.c (decode_mode_spec_coding):
16128 Adjust to CHAR_STRING's new requirement.
16129 * editfns.c (Finsert_char, Fsubst_char_in_region):
16130 * fns.c (concat): Check that character args are actually
16131 characters. Without this test, these functions did the wrong
16132 thing with wildly out-of-range values on 64-bit hosts.
16134 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
16135 These casts should not be needed on 32-bit hosts, either.
16136 * keyboard.c (read_char):
16137 * lread.c (Fload): Remove casts to unsigned.
16139 * lisp.h (UNSIGNED_CMP): New macro.
16140 This fixes comparison bugs on 64-bit hosts.
16141 (ASCII_CHAR_P): Use it.
16142 * casefiddle.c (casify_object):
16143 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
16144 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
16145 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
16146 * dispextern.h (FACE_FROM_ID):
16147 * keyboard.c (read_char): Use UNSIGNED_CMP.
16149 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
16150 not to EMACS_INT, to avoid GCC warning.
16152 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
16154 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
16155 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
16156 isn't needed on 32-bit machines.
16158 * buffer.c (Fgenerate_new_buffer_name):
16159 Use EMACS_INT for count, not int.
16160 (advance_to_char_boundary): Return EMACS_INT, not int.
16162 * data.c (Qcompiled_function): Now static.
16164 * window.c (window_body_lines): Now static.
16166 * image.c (gif_load): Rename local to avoid shadowing.
16168 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
16169 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
16170 * alloc.c (make_save_value): Integer argument is now of type
16171 ptrdiff_t, not int.
16172 (mark_object): Use ptrdiff_t, not int.
16173 * lisp.h (pD): New macro.
16174 * print.c (print_object): Use it.
16176 * alloc.c: Use EMACS_INT, not int, to count objects.
16177 (total_conses, total_markers, total_symbols, total_vector_size)
16178 (total_free_conses, total_free_markers, total_free_symbols)
16179 (total_free_floats, total_floats, total_free_intervals)
16180 (total_intervals, total_strings, total_free_strings):
16181 Now EMACS_INT, not int. All uses changed.
16182 (Fgarbage_collect): Compute overall total using a double, so that
16183 integer overflow is less likely to be a problem. Check for overflow
16184 when converting back to an integer.
16185 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
16186 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
16187 These were 'int' variables that could overflow on 64-bit hosts;
16188 they were never used, so remove them instead of repairing them.
16189 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
16190 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
16191 Previously, this ceilinged at INT_MAX, but that doesn't work on
16193 (allocate_pseudovector): Don't use EMACS_INT when int would do.
16195 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
16196 (allocate_vectorlike): Check for ptrdiff_t overflow.
16197 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
16198 when a (possibly-narrower) signed value would do just as well.
16199 We prefer using signed arithmetic, to avoid comparison confusion.
16201 * alloc.c: Catch some string size overflows that we were missing.
16202 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
16203 for convenience in STRING_BYTES_MAX.
16204 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
16205 The definition here is exact; the one in lisp.h was approximate.
16206 (allocate_string_data): Check for string overflow. This catches
16207 some instances we weren't catching before. Also, it catches
16208 size_t overflow on (unusual) hosts where SIZE_MAX <= min
16209 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
16210 and ptrdiff_t and EMACS_INT are both 64 bits.
16212 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
16213 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
16214 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
16216 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
16218 * alloc.c (Fmake_string): Check for out-of-range init.
16220 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
16222 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
16224 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
16226 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
16227 xg_get_default_scrollbar_width.
16229 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
16230 (int_gtk_range_get_value): Move to the scroll bar part of the file.
16231 (style_changed_cb): Call update_theme_scrollbar_width and call
16232 x_set_scroll_bar_default_width and xg_frame_set_char_size for
16233 all frames (Bug#8505).
16234 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
16235 Call gtk_window_set_resizable if HAVE_GTK3.

16237 and height if HAVE_GTK3 (Bug#8505).
16238 (scroll_bar_width_for_theme): New variable.
16239 (update_theme_scrollbar_width): New function.
16240 (xg_get_default_scrollbar_width): Move code to
16241 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
16242 (xg_initialize): Call update_theme_scrollbar_width.
16244 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
16246 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
16248 2011-06-12 Martin Rudalics <rudalics@gmx.at>
16250 * frame.c (make_frame): Call other_buffer_safely instead of
16253 * window.c (temp_output_buffer_show): Call display_buffer with
16254 second argument Vtemp_buffer_show_specifiers and reset latter
16255 immediately after the call.
16256 (Vtemp_buffer_show_specifiers): New variable.
16257 (auto_window_vscroll_p, next_screen_context_lines)
16258 (Vscroll_preserve_screen_position): Remove leading asterisks from

16441 Remove static from declaration of Qdelete_window, it's
16442 temporarily needed by Fbury_buffer.
16443 (replace_window): Don't assign orig_top_line and

16448 Replace Fdelete_window calls with calls to Qdelete_window.
16449 (Fdelete_other_windows): Remove. Deleting other windows is

16809 (display_prop_intangible_p): Reimplement to call
16810 handle_display_spec instead of single_display_spec_intangible_p.

16822 value of a `display' property is a "replacing spec".
16823 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
16824 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

16854 * gnutls.c: Use Emacs's memory allocators.
16855 Without this change, the gnutls library would invoke malloc etc.
16856 directly, which causes problems on non-SYNC_INPUT hosts, and which
16857 runs afoul of improving memory_full behavior. (Bug#8761)
16858 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
16859 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
16860 xfree instead of the default malloc, realloc, free.
16861 (Fgnutls_boot): No need to check for memory allocation failure,
16862 since xmalloc does that for us.

16885 for hashes and hash indexes, instead of 'unsigned' and 'int'.
16886 * alloc.c (allocate_vectorlike):
16887 Check for overflow in vector size calculations.
16888 * ccl.c (ccl_driver):
16889 Check for overflow when converting EMACS_INT to int.

16891 need to be updated by these changes.
16892 * fns.c (make_hash_table, maybe_resize_hash_table):
16893 Check for integer overflow with large hash tables.
16894 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
16895 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
16896 (SXHASH_REDUCE): New macro.
16897 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
16898 Use it instead of discarding useful hash info with large hash values.
16899 (sxhash_float): New function.
16900 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
16901 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
16902 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
16903 Rewrite to use FIXNUM_BITS, as this simplifies things.
16904 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
16905 Adjust signatures to match updated version of code.
16906 (consing_since_gc): Now EMACS_INT, since a single hash table can
16907 use more than INT_MAX bytes.

16922 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
16923 Update dependencies.
16925 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
16927 * data.c (init_data): Remove code for UTS, this system is not
16930 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
16932 Don't force ./temacs to start in terminal mode.
16934 * frame.c (make_initial_frame): Initialize faces in all cases, not
16935 only when CANNOT_DUMP is defined.
16936 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
16938 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
16940 * dispnew.c (add_window_display_history): Use const for the string
16941 pointer. Remove declaration, not needed.
16943 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
16945 Use 'inline', not 'INLINE'.
16946 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
16947 * alloc.c, fontset.c (INLINE): Remove.
16948 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
16949 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
16950 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
16951 * gmalloc.c (register_heapinfo): Use inline unconditionally.
16952 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
16954 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
16956 Make it possible to run ./temacs.
16958 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
16959 syms_of_callproc does the same thing. Remove test for
16960 "initialized", do it in the caller.
16961 * emacs.c (main): Avoid calling set_initial_environment when dumping.
16963 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
16965 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
16966 (read_minibuf): Use get_minibuffer.
16967 (syms_of_minibuf): Use DEFSYM.
16968 (Qmetadata): New var.
16969 * data.c (Qbuffer): Don't make it static.
16970 (syms_of_data): Use DEFSYM.
16972 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
16974 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
16975 (CCL_CODE_MIN): New macro.
16977 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
16979 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
16981 * eval.c (Qdebug): Now static.
16982 * lisp.h (Qdebug): Remove decl. This reverts a part of the
16983 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
16984 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
16986 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
16988 * image.c: Various fixes to ImageMagick code comments.
16989 (Fimagemagick_types): Doc fix.
16991 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
16993 Minor fixes prompted by GCC 4.6.0 warnings.
16995 * xselect.c (converted_selections, conversion_fail_tag): Now static.
16997 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
16998 (x_clipboard_manager_save_all): Move extern decl to ...
16999 * xterm.h: ... here, so that it can be checked for consistency.
17001 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
17003 * xselect.c (x_clipboard_manager_save_frame)
17004 (x_clipboard_manager_save_all): New functions.
17005 (Fx_clipboard_manager_save): Lisp function deleted.
17007 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
17008 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
17010 * xterm.h: Update prototype.
17012 2011-05-28 William Xu <william.xwl@gmail.com>
17014 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
17015 exiting (Bug#8239).
17017 2011-05-28 Jim Meyering <meyering@redhat.com>
17019 Avoid a sign-extension bug in crypto_hash_function.
17020 * fns.c (to_uchar): Define.
17021 (crypto_hash_function): Use it to convert some newly-signed
17022 variables to unsigned, to avoid sign-extension bugs. For example,
17023 without this change, (md5 "truc") would evaluate to
17024 45723a2aff78ff4fff7fff1114760e62 rather than the expected
17025 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
17026 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
17028 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17030 Integer overflow fixes.
17032 * dbusbind.c: Serial number integer overflow fixes.
17033 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
17034 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
17035 to hold a serial number that is too large for a fixnum.
17036 (Fdbus_method_return_internal, Fdbus_method_error_internal):
17037 Check for serial numbers out of range. Decode any serial number
17038 that was so large that it became a float. (Bug#8722)
17040 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
17041 (Fdbus_call_method, Fdbus_call_method_asynchronously):
17042 Use XFASTINT rather than XUINT when numbers are nonnegative.
17043 (xd_append_arg, Fdbus_method_return_internal):
17044 (Fdbus_method_error_internal): Likewise. Also, for unsigned
17045 arguments, check that Lisp number is nonnegative, rather than
17046 silently wrapping negative numbers around. (Bug#8722)
17047 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
17050 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
17052 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
17054 ccl: Add integer overflow checks.
17055 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
17056 (IN_INT_RANGE): New macros.
17057 (ccl_driver): Use them to check for integer overflow when
17058 decoding a CCL program. Many of the new checks are whether XINT (x)
17059 fits in int; it doesn't always, on 64-bit hosts. The new version
17060 doesn't catch all possible integer overflows, but it's an
17061 improvement. (Bug#8719)
17063 * alloc.c (make_event_array): Use XINT, not XUINT.
17064 There's no need for unsigned here.
17066 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
17067 This follows up to the 2011-05-06 change that substituted uintptr_t
17068 for EMACS_INT. This case wasn't caught back then.
17070 Rework Fformat to avoid integer overflow issues.
17071 * editfns.c: Include <float.h> unconditionally, as it's everywhere
17072 now (part of C89). Include <verify.h>.
17073 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
17074 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
17075 (Fformat): Avoid the prepass trying to compute sizes; it was only
17076 approximate and thus did not catch overflow reliably. Instead, walk
17077 through the format just once, formatting and computing sizes as we go,
17078 checking for integer overflow at every step, and allocating a larger
17079 buffer as needed. Keep track separately whether the format is
17080 multibyte. Keep only the most-recently calculated precision, rather
17081 than them all. Record whether each argument has been converted to
17082 string. Use EMACS_INT, not int, for byte and char and arg counts.
17083 Support field widths and precisions larger than INT_MAX. Avoid
17084 sprintf's undefined behavior with conversion specifications such as %#d
17085 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
17086 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
17087 formatting out-of-range floating point numbers with int
17088 formats. (Bug#8668)
17090 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
17092 * data.c: Avoid integer truncation in expressions involving floats.
17093 * data.c: Include <intprops.h>.
17094 (arith_driver): When there's an integer overflow in an expression
17095 involving floating point, convert the integers to floating point
17096 so that the resulting value does not suffer from catastrophic
17097 integer truncation. For example, on a 64-bit host (* 4
17098 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
17099 Do not rely on undefined behavior after integer overflow.
17101 merge count_size_as_multibyte, parse_str_to_multibyte
17102 * character.c, character.h (count_size_as_multibyte):
17103 Rename from parse_str_to_multibyte; all uses changed.
17104 Check for integer overflow.
17105 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
17106 since it's now a duplicate of the other. This is more of
17107 a character than a buffer op, so better that it's in character.c.
17108 * fns.c, print.c: Adjust to above changes.
17110 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
17112 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
17114 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17116 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17117 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
17118 (x_clipboard_manager_save): Now static.
17119 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
17121 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17122 (crypto_hash_function): Now static.
17123 Fix pointer signedness problems. Avoid unnecessary initializations.
17125 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
17127 * termhooks.h (Vselection_alist): Make it terminal-local.
17129 * terminal.c (create_terminal): Initialize it.
17131 * xselect.c: Support for clipboard managers.
17132 (Vselection_alist): Move to termhooks.h as terminal-local var.
17133 (LOCAL_SELECTION): New macro.
17134 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
17135 (symbol_to_x_atom): Remove gratuitous arg.
17136 (x_handle_selection_request, lisp_data_to_selection_data)
17137 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
17138 (x_own_selection, x_get_local_selection, x_convert_selection):
17139 New arg, specifying work frame. Use terminal-local Vselection_alist.
17140 (some_frame_on_display): Delete unused function.
17141 (Fx_own_selection_internal, Fx_get_selection_internal)
17142 (Fx_disown_selection_internal, Fx_selection_owner_p)
17143 (Fx_selection_exists_p): New optional frame arg.
17144 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
17145 (x_handle_selection_clear): Don't treat other terminals with the
17146 same keyboard specially. Use the terminal-local Vselection_alist.
17147 (x_clear_frame_selections): Use Frun_hook_with_args.
17149 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
17151 * xterm.h: Add support for those atoms.
17153 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
17155 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
17156 (converted_selections, conversion_fail_tag): New global variables.
17157 (x_selection_request_lisp_error): Free the above.
17158 (x_get_local_selection): Remove unnecessary code.
17159 (x_reply_selection_request): Args changed; handle arbitrary array
17160 of converted selections stored in converted_selections.
17161 Separate the XChangeProperty and SelectionNotify steps.
17162 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
17163 (x_convert_selection): New function.
17164 (x_handle_selection_event): Simplify.
17165 (x_get_foreign_selection): Don't ignore incoming requests while
17166 waiting for an answer; this will fail when we implement
17167 SAVE_TARGETS, and seems unnecessary anyway.
17168 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
17169 (Vx_sent_selection_functions): Doc fix.
17171 2011-05-26 Leo Liu <sdl.web@gmail.com>
17173 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
17175 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17177 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
17179 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
17180 for fringe update if it has periodic bitmap.
17181 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
17182 and fringe_bitmap_periodic_p.
17184 * fringe.c (get_fringe_bitmap_data): New function.
17185 (draw_fringe_bitmap_1, update_window_fringes): Use it.
17186 (update_window_fringes): Record periodicity of fringe bitmap in glyph
17187 row. Mark glyph row for fringe update if periodicity changed.
17189 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
17190 for fringe update unless it has periodic bitmap.
17192 2011-05-25 Kenichi Handa <handa@m17n.org>
17194 * xdisp.c (get_next_display_element): Set correct it->face_id for
17195 a static composition.
17197 2011-05-24 Leo Liu <sdl.web@gmail.com>
17200 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
17202 * fns.c (crypto_hash_function, Fsha1): New function.
17203 (Fmd5): Use crypto_hash_function.
17204 (syms_of_fns): Add Ssha1.
17206 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
17208 * gnutls.c: Remove unused macros.
17209 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
17210 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
17211 Remove macros that are defined and never used.
17212 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
17214 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17216 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
17217 (Fx_get_selection_internal): Minor cleanup.
17218 (Fx_own_selection_internal): Rename arguments for consistency with
17221 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
17223 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
17225 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17227 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
17229 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17231 * dispnew.c (scrolling_window): Don't exclude the case that the
17232 last enabled row in the desired matrix touches the bottom boundary.
17234 2011-05-21 Glenn Morris <rgm@gnu.org>
17236 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
17237 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
17238 and add some more files.
17240 2011-05-20 Eli Zaretskii <eliz@gnu.org>
17242 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
17243 report_file_error introduced by the change from 2011-05-07.
17245 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
17247 * systime.h (Time): Define only if emacs is defined.
17248 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
17249 where the include path doesn't have X11/X.h by default. See
17250 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
17252 2011-05-20 Kenichi Handa <handa@m17n.org>
17254 * composite.c (find_automatic_composition): Fix previous change.
17256 2011-05-20 Glenn Morris <rgm@gnu.org>
17258 * lisp.mk: New file, split from Makefile.in.
17259 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
17260 (shortlisp): Remove.
17261 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
17263 2011-05-19 Glenn Morris <rgm@gnu.org>
17265 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
17266 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
17267 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
17268 (lisp): Set the order to that of loadup.el.
17269 (shortlisp): Make it a copy of $lisp.
17270 (SOME_MACHINE_LISP): Remove.
17271 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
17272 Use just $shortlisp, not $SOME_MACHINE_LISP too.
17274 2011-05-18 Kenichi Handa <handa@m17n.org>
17276 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
17277 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
17278 (find_automatic_composition): Mostly rewrite for efficiency.
17280 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
17282 * makefile.w32-in: Update dependencies.
17284 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
17286 * menu.c: Include limits.h (fixes the MS-Windows build broken by
17287 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
17289 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
17291 Fix some integer overflow issues, such as string length overflow.
17293 * insdel.c (count_size_as_multibyte): Check for string overflow.
17295 * character.c (lisp_string_width): Check for string overflow.
17296 Use EMACS_INT, not int, for string indexes and lengths; in
17297 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
17298 the resulting string length overflows an EMACS_INT; instead,
17299 report a string overflow if no precision given. When checking for
17300 precision exhaustion, use a check that cannot possibly have
17301 integer overflow. (Bug#8675)
17302 * character.h (lisp_string_width): Adjust to new signature.
17304 * alloc.c (string_overflow): New function.
17305 (Fmake_string): Use it. This doesn't change behavior, but saves
17306 a few bytes and will simplify future changes.
17307 * character.c (string_escape_byte8): Likewise.
17308 * lisp.h (string_overflow): New decl.
17310 Fixups, following up to the user-interface timestamp change.
17311 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
17312 for UI timestamps, instead of unsigned long.
17313 * msdos.c (mouse_get_pos): Likewise.
17314 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
17315 * w32gui.h (Time): Define by including "systime.h" rather than by
17316 declaring it ourselves. (Bug#8664)
17318 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
17319 * image.c (clear_image_cache): Likewise.
17321 * term.c (term_mouse_position): Don't assume time_t wraparound.
17323 Be more systematic about user-interface timestamps.
17324 Before, the code sometimes used 'Time', sometimes 'unsigned long',
17325 and sometimes 'EMACS_UINT', to represent these timestamps.
17326 This change causes it to use 'Time' uniformly, as that's what X uses.
17327 This makes the code easier to follow, and makes it easier to catch
17328 integer overflow bugs such as Bug#8664.
17329 * frame.c (Fmouse_position, Fmouse_pixel_position):
17330 Use Time, not unsigned long, for user-interface timestamps.
17331 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
17332 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
17333 * keyboard.h (last_event_timestamp): Likewise.
17334 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
17335 * menu.h (xmenu_show): Likewise.
17336 * term.c (term_mouse_position): Likewise.
17337 * termhooks.h (struct input_event.timestamp): Likewise.
17338 (struct terminal.mouse_position_hook): Likewise.
17339 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
17340 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
17341 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
17342 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
17343 what it was before.
17344 * menu.h, termhooks.h: Include "systime.h", for Time.
17346 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
17347 Don't assume that the difference between two unsigned long values
17348 can fit into an integer. At this point, we know button_down_time
17349 <= event->timestamp, so the difference must be nonnegative, so
17350 there's no need to cast the result if double-click-time is
17351 nonnegative, as it should be; check that it's nonnegative, just in
17352 case. This bug is triggered when events are more than 2**31 ms
17353 apart (about 25 days). (Bug#8664)
17355 * xselect.c (last_event_timestamp): Remove duplicate decl.
17356 (x_own_selection): Remove needless cast to unsigned long.
17358 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
17359 that always fit in int. Use a sentinel instead of a counter, to
17360 avoid a temp and to allay GCC's concerns about possible int overflow.
17361 * frame.h (struct frame): Use int for menu_bar_items_used
17362 instead of EMACS_INT, since it always fits in int.
17364 * menu.c (grow_menu_items): Check for int overflow.
17366 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
17368 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
17369 Before, the code was not consistent. These values cannot exceed
17370 2**31 - 1 so there's no need to make them unsigned.
17371 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
17372 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
17373 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
17375 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
17377 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
17378 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
17379 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
17380 presumably because the widths might not match.
17382 * window.c (size_window): Avoid needless test at loop start.
17384 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
17386 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
17388 2011-05-12 Drew Adams <drew.adams@oracle.com>
17390 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
17392 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17394 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
17395 `width' to `bar_area_x' and `bar_area_width', respectively.
17396 (x_scroll_run): Take account of fringe background extension.
17398 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
17399 Rename local vars `left' and `width' to `bar_area_x' and
17400 `bar_area_width', respectively.
17401 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
17402 background extension.
17404 2011-05-10 Jim Meyering <meyering@redhat.com>
17406 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
17408 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
17410 * image.c (Finit_image_library): Return t for built-in image types,
17411 like pbm and xbm. (Bug#8640)
17413 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
17415 * w32menu.c (set_frame_menubar): Fix submenu allocation.
17417 2011-05-07 Eli Zaretskii <eliz@gnu.org>
17419 * w32console.c (Fset_screen_color): Doc fix.
17420 (Fget_screen_color): New function.
17421 (syms_of_ntterm): Defsubr it.
17423 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
17424 unlink the temporary file if Fcall_process didn't create it in the
17426 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
17427 child process will be redirected to a file specified with `:file'.
17428 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
17429 cue to call_process_cleanup not to close that handle.
17431 2011-05-07 Ben Key <bkey76@gmail.com>
17433 * makefile.w32-in: The bootstrap-temacs rule now makes use of
17434 one of two shell specific rules, either bootstrap-temacs-CMD or
17435 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
17436 to the previous implementation of the bootstrap-temacs rule.
17437 The bootstrap-temacs-CMD rule is similar to the previous
17438 implementation of the bootstrap-temacs rule except that it
17439 makes use of the ESC_CFLAGS variable instead of the CFLAGS
17442 These changes, along with some changes to nt/configure.bat,
17443 nt/gmake.defs, and nt/nmake.defs, are required to extend my
17444 earlier fix to add support for --cflags and --ldflags options
17445 that include quotes so that it works whether make uses cmd or
17448 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
17450 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
17451 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
17453 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
17454 a string. Handle both cases.
17455 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
17456 (Fdbus_register_method): Use Qinvalid_function.
17458 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
17460 * makefile.w32-in: Update dependencies.
17461 (LISP_H): Add inttypes.h and stdin.h.
17462 (PROCESS_H): Add unistd.h.
17464 2011-05-06 Eli Zaretskii <eliz@gnu.org>
17466 * lread.c: Include limits.h (fixes the MS-Windows build broken by
17467 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
17469 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
17471 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
17473 * term.c (vfatal): Remove stray call to va_end.
17474 It's not needed and the C Standard doesn't allow it here anyway.
17476 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
17477 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
17479 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
17482 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
17484 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
17486 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
17488 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
17490 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
17492 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
17493 * charset.c (Fdefine_charset_internal): Don't initialize
17494 charset.code_space[15]. The value was garbage, on hosts with
17495 32-bit int (Bug#8600).
17497 * lread.c (read_integer): Be more consistent with string-to-number.
17498 Use string_to_number to do the actual conversion; this avoids
17499 rounding errors and fixes some other screwups. Without this fix,
17500 for example, #x1fffffffffffffff was misread as -2305843009213693952.
17501 (digit_to_number): Move earlier, for benefit of read_integer.
17502 Return -1 if the digit is out of range for the base, -2 if it is
17503 not a digit in any supported base. (Bug#8602)
17505 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
17507 * dispnew.c (scrolling_window): Return 1 if we scrolled,
17508 to match comment at start of function. This also removes a
17509 GCC warning about overflow in a 32+64-bit port.
17511 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
17513 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
17514 Reported by Stefan Monnier in
17515 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
17516 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
17517 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
17519 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
17520 (EMACS_UINTPTR): Likewise, with uintptr_t.
17522 * lisp.h: Prefer 64-bit EMACS_INT if available.
17523 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
17524 on 32-bit hosts that have 64-bit int, so that they can access
17526 However, temporarily disable this change unless the temporary
17527 symbol WIDE_EMACS_INT is defined.
17529 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
17531 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
17532 This removes an assumption that EMACS_INT and long are the same
17533 width as pointers. The assumption is true for Emacs porting targets
17534 now, but we want to make other targets possible.
17535 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
17536 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
17537 In the rest of the code, change types of integers that hold casted
17538 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
17539 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
17540 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
17541 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
17542 No need to cast type when ORing.
17543 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
17544 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
17545 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
17546 assume EMACS_INT is the same width as char *.
17547 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
17548 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
17549 Remove no-longer-needed casts.
17550 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
17551 (xg_tool_bar_help_callback, xg_make_tool_item):
17552 Use EMACS_INTPTR to hold an integer
17553 that will be cast to void *; this can avoid a GCC warning
17554 if EMACS_INT is not the same width as void *.
17555 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
17556 * xdisp.c (display_echo_area_1, resize_mini_window_1):
17557 (current_message_1, set_message_1):
17558 Use a local to convert to proper width without a cast.
17559 * xmenu.c (dialog_selection_callback): Likewise.
17561 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
17562 Also, don't assume VALBITS / RAND_BITS is less than 5,
17563 and don't rely on undefined behavior when shifting a 1 left into
17565 * lisp.h (get_random): Change signature to match.
17567 * lread.c (hash_string): Use size_t, not int, for hash computation.
17568 Normally we prefer signed values; but hashing is special, because
17569 it's better to use unsigned division on hash table sizes so that
17570 the remainder is nonnegative. Also, size_t is the natural width
17571 for hashing into memory. The previous code used 'int', which doesn't
17572 retain enough info to hash well into very large tables.
17573 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
17575 * dbusbind.c: Don't possibly lose pointer info when converting.
17576 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
17577 Use XPNTR rather than XHASH, so that the high-order bits of
17578 the pointer aren't lost when converting through void *.
17580 * eval.c (Fautoload): Don't double-shift a pointer.
17582 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
17584 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
17586 * gnutls.c (DEF_GNUTLS_FN):
17587 * image.c (DEF_IMGLIB_FN): Make function pointers static.
17589 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
17591 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
17594 2011-05-05 Eli Zaretskii <eliz@gnu.org>
17596 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
17597 New version that can reserve upto 2GB of heap space.
17599 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
17601 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
17603 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
17605 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
17606 `gnutls_certificate_set_x509_key_file'.
17608 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
17610 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
17611 Update dependencies.
17613 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
17615 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
17616 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
17617 Remove unused parameter `fildes'.
17618 * process.c (read_process_output, send_process): Don't pass it.
17620 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
17622 Fix previous change: the library cache is defined in w32.c.
17623 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
17624 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
17626 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
17628 Implement dynamic loading of GnuTLS on Windows.
17630 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
17631 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
17632 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
17635 * gnutls.c (Qgnutls_dll): Define.
17636 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
17637 (gnutls_*): Declare function pointers.
17638 (init_gnutls_functions): New function to initialize function pointers.
17639 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
17640 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
17641 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
17642 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
17643 (emacs_gnutls_write, emacs_gnutls_read)
17644 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
17645 (Fgnutls_available_p): New function.
17646 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
17647 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
17648 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
17650 * image.c: Include w32.h.
17651 (Vimage_type_cache): Delete.
17652 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
17653 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
17654 (w32_delayed_load): Move to w32.c.
17656 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
17658 * w32.c (QCloaded_from, Vlibrary_cache): Define.
17659 (w32_delayed_load): Move from image.c. When loading a library, record
17660 its filename in the :loaded-from property of the library id.
17661 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
17662 Initialize and staticpro them.
17663 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
17665 * process.c: Include lisp.h before w32.h, not after.
17666 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
17667 instead of gnutls_record_check_pending.
17669 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
17671 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
17673 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
17674 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
17677 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
17679 * xterm.c (x_set_frame_alpha): Do not set property on anything
17680 else than FRAME_X_OUTER_WINDOW (Bug#8608).

17695 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
17696 (Qgnutls_bootprop_callbacks_verify): Make static.
17698 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
17700 * callproc.c: Indentation fixup.
17702 * sysdep.c (wait_for_termination_1): Make static.
17703 (wait_for_termination, interruptible_wait_for_termination):
17704 Move after wait_for_termination_1.
17706 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
17708 * sysdep.c (interruptible_wait_for_termination): New function
17709 which is like wait_for_termination, but allows keyboard
17712 * callproc.c (Fcall_process): Add (:file "file") as an option for
17714 (Fcall_process_region): Ditto.
17716 2011-04-30 Eli Zaretskii <eliz@gnu.org>
17718 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
17719 rather than `XVECTOR (FOO)->size'.
17721 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
17722 inttypes.h, as a gnulib replacement is used if it not available in
17725 2011-04-21 Eli Zaretskii <eliz@gnu.org>
17727 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
17728 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
17729 of MOST_POSITIVE_FIXNUM. (Bug#8528)
17731 * coding.c (coding_alloc_by_realloc): Error out if destination
17732 will grow beyond MOST_POSITIVE_FIXNUM.
17733 (decode_coding_emacs_mule): Abort if there isn't enough place in

17744 %llo or %llx format is passed. (Bug#8545)
17746 * window.c (window_scroll_line_based): Use a marker instead of
17747 simple variables to record original value of point. (Bug#7952)
17749 * doprnt.c (doprnt): Fix the case where a multibyte sequence
17750 produced by %s or %c overflows available buffer space. (Bug#8545)
17752 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
17754 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
17755 (SIZE_MAX): Move defn after all includes, as they might #define it.
17757 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
17759 * w32.c (init_environment): Warn about defaulting HOME to C:\.

17783 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
17785 * makefile.w32-in: Update dependencies.

17789 Improve `doprnt' and its usage. (Bug#8545)
17790 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
17791 `format_end'. Remove support for %l as a conversion specifier.
17792 Don't use xrealloc. Improve diagnostics when the %l size modifier
17793 is used. Update the commentary.
17795 * eval.c (verror): Simplify calculation of size_t.
17797 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
17800 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
17802 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
17805 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
17807 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
17808 This makes this file independent of the recent pseudovector change.
17810 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
17812 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
17814 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
17815 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
17816 Remove unused local.
17817 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
17819 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
17820 GCC 4.6.0 optimizes based on type-based alias analysis.
17821 For example, if b is of type struct buffer * and v of type struct
17822 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
17823 != &v->size, and therefore "v->size = 1; b->size = 2; return
17824 v->size;" must therefore return 1. This assumption is incorrect
17825 for Emacs, since it type-puns struct Lisp_Vector * with many other
17826 types. To fix this problem, this patch adds a new type struct
17827 vectorlike_header that documents the constraints on layout of vectors
17828 and pseudovectors, and helps optimizing compilers not get fooled
17829 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
17830 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
17831 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
17833 (XSETPVECTYPE): Rewrite in terms of new macro.
17834 (XSETPVECTYPESIZE): New macro, specifying both type and size.
17835 This is a bit clearer, and further avoids the possibility of
17836 undesirable aliasing.
17837 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
17838 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
17839 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
17840 since Lisp_Subr is a special case (no "next" field).
17841 (ASIZE): Now uses header.size rather than size.
17842 All previous uses of XVECTOR (foo)->size replaced to use this macro,
17843 to avoid the hassle of writing XVECTOR (foo)->header.size.
17844 (struct vectorlike_header): New type.
17845 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
17846 object, to help avoid aliasing.
17847 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
17848 (SUBRP): Likewise, since Lisp_Subr is a special case.
17849 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
17850 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
17851 (struct Lisp_Hash_Table): Combine first two members into a single
17852 struct vectorlike_header member. All uses of "size" and "next" members
17853 changed to be "header.size" and "header.next".
17854 * buffer.h (struct buffer): Likewise.
17855 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
17856 * frame.h (struct frame): Likewise.
17857 * process.h (struct Lisp_Process): Likewise.
17858 * termhooks.h (struct terminal): Likewise.
17859 * window.c (struct save_window_data, struct saved_window): Likewise.
17860 * window.h (struct window): Likewise.
17861 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
17862 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
17863 * buffer.c (init_buffer_once): Likewise.
17864 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
17866 * process.c (Fformat_network_address): Use local var for size,
17869 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
17871 Make the Lisp reader and string-to-float more consistent (Bug#8525)
17872 * data.c (atof): Remove decl; no longer used or needed.
17873 (digit_to_number): Move to lread.c.
17874 (Fstring_to_number): Use new string_to_number function, to be
17875 consistent with how the Lisp reader treats infinities and NaNs.
17876 Do not assume that floating-point numbers represent EMACS_INT
17877 without losing information; this is not true on most 64-bit hosts.
17878 Avoid double-rounding errors, by insisting on integers when
17879 parsing non-base-10 numbers, as the documentation specifies.
17880 * lisp.h (string_to_number): New decl, replacing ...
17881 (isfloat_string): Remove.
17882 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
17883 (read1): Do not accept +. and -. as integers; this
17884 appears to have been a coding error. Similarly, do not accept
17885 strings like +-1e0 as floating point numbers. Do not report
17886 overflow for integer overflows unless the base is not 10 which
17887 means we have no simple and reliable way to continue.
17888 Break out the floating-point parsing into a new
17889 function string_to_number, so that Fstring_to_number parses
17890 floating point numbers consistently with the Lisp reader.
17891 (digit_to_number): Move here from data.c. Make it static inline.
17892 (E_CHAR, EXP_INT): Remove, replacing with ...
17893 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
17894 (string_to_number): New function, replacing isfloat_string.
17895 This function checks for valid syntax and produces the resulting
17896 Lisp float number too. Rework it so that string-to-number
17897 no longer mishandles examples like "1.0e+". Use strtoumax,
17898 so that overflow for non-base-10 numbers is reported only when
17899 there's no portable and simple way to convert to floating point.
17901 * textprop.c (set_text_properties_1): Rewrite for clarity,
17902 and to avoid GCC warning about integer overflow.
17904 * intervals.h (struct interval): Use EMACS_INT for members
17905 where EMACS_UINT might cause problems. See
17906 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
17907 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
17908 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
17910 (offset_intervals): Tell GCC not to worry about length overflow
17911 when negating a negative length.
17913 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
17914 (overrun_check_free): Likewise.
17916 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
17917 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
17920 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
17921 (gnutls_make_error): Rename local to avoid shadowing.
17922 (gnutls_emacs_global_deinit): ifdef out; not used.
17923 (Fgnutls_boot): Use const for pointer to readonly storage.
17924 Comment out unused local. Fix pointer signedness problems.
17926 * lread.c (openp): Don't stuff size_t into an 'int'.
17927 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
17928 about possible signed overflow.
17930 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
17931 (GDK_KEY_g): Don't define if already defined.
17932 (xg_prepare_tooltip): Avoid pointer signedness problem.
17933 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
17935 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
17936 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
17938 * xfns.c (Fx_window_property): Simplify a bit,
17939 to make a bit faster and to avoid GCC 4.6.0 warning.
17940 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
17942 * fns.c (internal_equal): Don't assume size_t fits in int.
17944 * alloc.c (compact_small_strings): Tighten assertion a little.
17946 Replace pEd with more-general pI, and fix some printf arg casts.
17947 * lisp.h (pI): New macro, generalizing old pEd macro to other
17948 conversion specifiers. For example, use "...%"pI"d..." rather
17949 than "...%"pEd"...".
17950 (pEd): Remove. All uses replaced with similar uses of pI.
17951 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
17952 * alloc.c (check_pure_size): Don't overflow by converting size to int.
17953 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
17954 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
17955 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
17956 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
17957 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
17959 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
17960 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
17961 * print.c (safe_debug_print, print_object): Likewise.
17962 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
17964 Use pI instead of if-then-else-abort. Use %p to avoid casts,
17965 avoiding the 0 flag, which is not portable.
17966 * process.c (Fmake_network_process): Use pI to avoid cast.
17967 * region-cache.c (pp_cache): Likewise.
17968 * xdisp.c (decode_mode_spec): Likewise.
17969 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
17970 behavior on 64-bit hosts with printf arg.
17971 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
17972 (x_stop_queuing_selection_requests): Likewise.
17973 (x_get_window_property): Don't truncate byte count to an 'int'
17976 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
17977 here, since it parses constructs like leading '-' and spaces,
17978 which are not wanted; and it overflows with large numbers.
17979 Instead, simply match F[0-9]+, which is what is wanted anyway.
17981 * alloc.c: Remove unportable assumptions about struct layout.
17982 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
17983 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
17984 (allocate_vectorlike, make_pure_vector): Use the new macros,
17985 plus offsetof, to remove unportable assumptions about struct layout.
17986 These assumptions hold on all porting targets that I know of, but
17987 they are not guaranteed, they're easy to remove, and removing them
17988 makes further changes easier.
17990 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
17991 This doesn't fix a bug but makes the code clearer.
17992 (string_overrun_cookie): Now const. Use initializers that
17993 don't formally overflow signed char, to avoid warnings.
17994 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
17995 can cause Emacs to crash when string overrun checking is enabled.
17996 (allocate_buffer): Don't assume sizeof (struct buffer) is a
17997 multiple of sizeof (EMACS_INT); it need not be, if
17998 alignof(EMACS_INT) < sizeof (EMACS_INT).
17999 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
18001 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

18008 supposed to be handshaking. (Bug#8556)
18009 Reported by Paul Eggert <eggert@cs.ucla.edu>.
18011 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

18028 2011-04-25 Eli Zaretskii <eliz@gnu.org>
18030 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
18031 "cast to pointer from integer of different size".
18033 Improve doprnt and its use in verror. (Bug#8545)
18034 * doprnt.c (doprnt): Document the set of format control sequences
18035 supported by the function. Use SAFE_ALLOCA instead of always
18038 * eval.c (verror): Don't limit the buffer size at size_max-1, that
18039 is one byte too soon. Don't use xrealloc; instead xfree and
18042 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
18044 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
18047 * gnutls.c: Renamed global_initialized to
18048 gnutls_global_initialized. Added internals for the
18049 :verify-hostname-error, :verify-error, and :verify-flags
18050 parameters of `gnutls-boot' and documented those parameters in the
18051 docstring. Start callback support.
18052 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
18053 unless a fatal error occurred. Call gnutls_alert_send_appropriate
18054 on error. Return error code.
18055 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
18056 (emacs_gnutls_read): Likewise.
18057 (Fgnutls_boot): Return handshake error code.
18058 (emacs_gnutls_handle_error): New function.

18121 <char-direction-table>: Deleted.
18123 2011-04-23 Eli Zaretskii <eliz@gnu.org>
18125 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
18126 * doprnt.c: Include limits.h.
18127 (SIZE_MAX): New macro.
18128 (doprnt): Return a size_t value. 2nd arg is now size_t.
18129 Many local variables are now size_t instead of int or unsigned.
18130 Improve overflow protection. Support `l' modifier for integer
18131 conversions. Support %l conversion. Don't assume an EMACS_INT
18132 argument for integer conversions and for %c.
18134 * lisp.h (doprnt): Restore prototype.
18136 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
18137 $(SRC)/character.h.
18139 * Makefile.in (base_obj): Add back doprnt.o.
18141 * deps.mk (doprnt.o): Add back prerequisites.
18142 (callint.o): Depend on character.h.
18144 * eval.c (internal_lisp_condition_case): Include the handler
18145 representation in the error message.
18146 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
18147 when breaking from the loop.
18149 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
18151 * callint.c (Fcall_interactively): When displaying error message
18152 about invalid control letter, pass the character's codepoint, not
18153 a pointer to its multibyte form. Improve display of the character
18154 in octal and display also its hex code.
18156 * character.c (char_string): Use %x to display the (unsigned)
18157 codepoint of an invalid character, to avoid displaying a bogus
18160 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
18161 `error', not SYMBOL_NAME itself.
18163 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
18164 character arguments to `error'.
18166 * charset.c (check_iso_charset_parameter): Fix incorrect argument
18167 to `error' in error message about FINAL_CHAR argument. Make sure
18168 FINAL_CHAR is a character, and use %c when it is passed as
18169 argument to `error'.

18233 Define only if needed.
18235 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
18236 by pacifying GCC about it. Maybe it's time to retire it?

18712 * casetab.c (Vascii_upcase_table, Vascii_eqv_table): Now static.
18713 * lisp.h: Remove these decls.
18715 * buffer.c (buffer_count): Remove unused var.
18717 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
18718 so that it's not optimized away.
18719 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
18720 * dispextern.h (bidi_dump_cached_states): Remove, since it's
18721 exported only to the debugger.
18723 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
18724 * atimer.h (run_all_atimers): Remove; not exported.
18726 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
18727 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
18728 was inaccessible from Lisp.
18729 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
18730 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
18732 alloc.c: Import and export fewer symbols, and remove unused items.
18733 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
18735 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
18736 it's not optimized away by whole-program optimization.
18737 (message_enable_multibyte, free_misc): Remove.
18738 (catchlist, handlerlist, mark_backtrace):
18739 Declare only if BYTE_MARK_STACK.
18740 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
18741 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
18742 (message_enable_multibyte): Remove decl.

18748 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
18749 (mark_backtrace): Define only if BYTE_MARK_STACK.
18750 * xdisp.c (message_enable_multibyte): Now static.
18752 Declare Lisp_Object Q* variables to be 'static' if not exported.
18753 This makes it easier for human readers (and static analyzers)
18754 to see whether these variables are used from other modules.
18755 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
18756 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
18757 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

18761 * xmenu.c, xselect.c:
18762 Declare Q* vars static if they are not used in other modules.

18764 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
18765 Remove decls of unexported vars.
18766 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
18768 * lisp.h (DEFINE_FUNC): Make sname 'static'.
18770 Make Emacs functions such as Fatom 'static' by default.
18771 This makes it easier for human readers (and static analyzers)
18772 to see whether these functions can be called from other modules.
18773 DEFUN now defines a static function. To make the function external
18774 so that it can be used in other C modules, use the new macro DEFUE.
18775 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
18776 (Finit_image_library):
18777 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
18778 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
18779 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
18780 Remove decls, since these functions are now static.
18781 (Funintern, Fget_internal_run_time): New decls, since these functions
18782 were already external.
18784 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
18785 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

18791 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
18792 Mark functions with DEFUE instead of DEFUN,
18793 if they are used in other modules.
18794 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
18795 decls for now-static functions.
18796 * buffer.h (Fdelete_overlay): Remove decl.
18797 * callproc.c (Fgetenv_internal): Mark as internal.

18806 * image.c (Finit_image_library): New forward static decl.
18807 * insdel.c (Fcombine_after_change_execute): Make forward decl static.

18832 2011-04-13 Eli Zaretskii <eliz@gnu.org>
18834 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
18835 when at ZV. (Bug#8487)
18837 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
18839 * charset.c (Fclear_charset_maps): Use xfree instead of free.

18842 * sound.c (sound_cleanup, alsa_close): Likewise.
18843 * termcap.c (tgetent): Likewise.
18844 * xfns.c (x_default_font_parameter): Likewise.
18845 * xsettings.c (read_and_apply_settings): Likewise.
18847 * alloc.c (overrun_check_malloc, overrun_check_realloc)
18848 (overrun_check_free): Protoize.
18850 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
18852 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
18853 since callers should never pass a negative size.
18854 Change the signature to match that of plain 'read' and 'write'; see
18855 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
18856 * lisp.h: Update prototypes of emacs_write and emacs_read.
18858 2011-04-11 Eli Zaretskii <eliz@gnu.org>
18860 * xdisp.c (redisplay_window): Don't try to determine the character
18861 position of the scroll margin if the window start point w->startp
18862 is outside the buffer's accessible region. (Bug#8468)
18864 2011-04-10 Eli Zaretskii <eliz@gnu.org>
18866 Fix write-region and its subroutines for buffers > 2GB.
18867 * fileio.c (a_write, e_write): Modify declaration of arguments and
18868 local variables to support buffers larger than 2GB.
18869 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
18871 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
18872 argument, local variables, and return value.
18874 * lisp.h: Update prototypes of emacs_write and emacs_read.
18876 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
18878 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
18880 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
18882 Fix more problems found by GCC 4.6.0's static checks.
18884 * xdisp.c (vmessage): Use a better test for character truncation.
18886 * charset.c (load_charset_map): <, not <=, for optimization,
18887 and to avoid potential problems with integer overflow.
18888 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
18889 * casetab.c (set_identity, shuffle): Likewise.
18890 * editfns.c (Fformat): Likewise.
18891 * syntax.c (skip_chars): Likewise.
18893 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
18894 This also lets GCC 4.6.0 generate slightly better loop code.
18896 * callint.c (Fcall_interactively): <, not <=, for optimization.
18897 (Fcall_interactively): Count the number of arguments produced,
18898 not the number of arguments given. This is simpler and lets GCC
18899 4.6.0 generate slightly better code.
18901 * ftfont.c: Distingish more carefully between FcChar8 and char.
18902 The previous code passed unsigned char * to a functions like
18903 strlen and xstrcasecmp that expect char *, which does not
18904 conform to the C standard.
18905 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
18906 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
18907 char * when the C standard requires it.
18909 * keyboard.c (read_char): Remove unused var.
18911 * eval.c: Port to Windows vsnprintf (Bug#8435).
18912 Include <limits.h>.
18913 (SIZE_MAX): Define if the headers do not.
18914 (verror): Do not give up if vsnprintf returns a negative count.
18915 Instead, grow the buffer. This ports to Windows vsnprintf, which
18916 does not conform to C99. Problem reported by Eli Zaretskii.
18917 Also, simplify the allocation scheme, by avoiding the need for
18918 calling realloc, and removing the ALLOCATED variable.
18920 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
18922 Remove invocations of doprnt, as Emacs now uses vsnprintf.
18923 But keep the doprint source code for now, as we might revamp it
18924 and use it again (Bug#8435).
18925 * lisp.h (doprnt): Remove.
18926 * Makefile.in (base_obj): Remove doprnt.o.
18927 * deps.mk (doprnt.o): Remove.
18929 error: Print 32- and 64-bit integers portably (Bug#8435).
18930 Without this change, on typical 64-bit hosts error ("...%d...", N)
18931 was used to print both 32- and 64-bit integers N, which relied on
18932 undefined behavior.
18933 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
18934 * lisp.h (error, verror): Mark as printf-like functions.
18935 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
18936 Report overflow in size calculations when allocating printf buffer.
18937 Do not truncate output string at its first null byte.
18938 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
18939 Truncate the output at a character boundary, since vsnprintf does not
18941 * charset.c (check_iso_charset_parameter): Convert internal
18942 character to string before calling 'error', since %c now has the
18944 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
18945 overflow when computing char to be passed to 'error'. Do not
18946 pass Lisp_Object to 'error'; pass the integer instead.
18947 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
18948 formatted with plain %d.
18950 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
18952 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
18954 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
18956 * xterm.c (x_catch_errors): Remove duplicate declaration.
18958 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
18960 * xdisp.c, lisp.h (message_nolog): Remove; unused.
18962 2011-04-10 Jim Meyering <meyering@redhat.com>
18964 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
18965 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
18966 return ssize_t not "int", and use size_t as the buffer length.
18967 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
18968 * gnutls.h: Update declarations.
18969 * process.c (read_process_output): Use ssize_t, to match.
18970 (send_process): Likewise.
18972 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
18974 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
18976 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
18978 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
18979 Use unsigned char, to match FcChar8 type definition.
18981 * xterm.c (handle_one_xevent):
18982 * xmenu.c (create_and_show_popup_menu):
18983 * xselect.c (x_decline_selection_request)
18984 (x_reply_selection_request): Avoid type-punned deref of X events.
18986 2011-04-09 Eli Zaretskii <eliz@gnu.org>
18988 Fix some uses of `int' instead of EMACS_INT.
18989 * search.c (string_match_1, fast_string_match)
18990 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
18991 (scan_buffer, find_next_newline_no_quit)
18992 (find_before_next_newline, search_command, Freplace_match)
18993 (Fmatch_data): Make some `int' variables be EMACS_INT.
18995 * xdisp.c (display_count_lines): 3rd argument and return value now
18996 EMACS_INT. All callers changed.
18997 (pint2hrstr): Last argument is now EMACS_INT.
18999 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
19000 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)

19010 (encode_coding_emacs_mule, encode_invocation_designation)
19011 (encode_designation_at_bol, encode_coding_iso_2022)
19012 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
19013 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
19015 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
19016 (encode_invocation_designation): Last argument P_NCHARS is now
19018 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
19019 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
19021 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
19024 * ccl.c (Fccl_execute_on_string): Declare some variables
19027 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
19029 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
19031 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
19033 * process.c (Fformat_network_address): Doc fix.
19035 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
19037 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
19039 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
19041 * keyboard.c (read_char): Call Lisp function help-form-show,
19042 instead of using internal_with_output_to_temp_buffer.
19043 (Qhelp_form_show): New var.
19044 (syms_of_keyboard): Use DEFSYM macro.
19046 * print.c (internal_with_output_to_temp_buffer): Function deleted.

19053 (list_processes_1): Delete.
19055 2011-04-06 Eli Zaretskii <eliz@gnu.org>
19057 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
19059 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
19061 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
19063 Fix more problems found by GCC 4.6.0's static checks.
19065 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
19067 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
19069 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
19071 * xdisp.c (vmessage): Mark as a printf-like function.
19073 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
19075 * sound.c (sound_warning): Don't crash if arg contains a printf format.
19077 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
19078 printf-like functions.
19079 (tiff_load): Add casts to remove these marks before passing them
19080 to system-supplied API.
19082 * eval.c (Fsignal): Remove excess argument to 'fatal'.
19084 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
19085 This avoids several warnings with gcc -Wstrict-overflow.
19086 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
19087 directly, rather than having caller test rule sign. This avoids
19088 some unnecessary tests.
19089 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
19090 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
19091 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
19093 * xfont.c (xfont_text_extents): Remove var that was set but not used.
19094 (xfont_open): Avoid unnecessary tests.
19096 * composite.c (composition_gstring_put_cache): Use unsigned integer.

19105 by using the new macro.
19107 * textprop.c (set_text_properties_1): Change while to do-while,
19108 since the condition is always true at first.
19110 * intervals.c (graft_intervals_into_buffer): Mark var as used.
19111 (interval_deletion_adjustment): Return unsigned value.
19114 * process.c (list_processes_1, create_pty, read_process_output):

19130 * print.c (print_error_message): Avoid int overflow.
19132 * font.c (font_list_entities): Redo for clarity,
19133 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.

19148 (wordify): Omit three unnecessary tests.
19150 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
19151 All callers changed. This avoids the need for an unused var.
19153 * casefiddle.c (casify_region): Remove var that is set but not used.
19155 * dired.c (file_name_completion): Remove var that is set but not used.
19157 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
19159 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
19160 (Finsert_file_contents): Remove unnecessary code checking fd.
19162 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
19163 Check for integer overflow on size calculations.
19165 * buffer.c (Fprevious_overlay_change): Remove var that is set
19168 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
19169 Remove vars that are set but not used.
19170 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
19171 (timer_check_2): Mark vars as initialized.
19173 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
19175 * image.c (lookup_image): Remove var that is set but not used.
19176 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
19178 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
19179 that are set but not used.
19181 * xfns.c (make_invisible_cursor): Don't return garbage
19182 if XCreateBitmapFromData fails (Bug#8410).
19184 * xselect.c (x_get_local_selection, x_handle_property_notify):
19185 Remove vars that are set but not used.
19187 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
19188 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
19190 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
19191 Remove var that is set but not used.
19192 (scroll_bar_windows_size): Now size_t, not int.
19193 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
19194 Check for overflow.
19196 * xfaces.c (realize_named_face): Remove vars that are set but not used.
19197 (map_tty_color) [!defined MSDOS]: Likewise.
19199 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
19201 * coding.c: Remove vars that are set but not used.
19202 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
19203 All callers changed.
19204 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
19205 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
19206 (decode_coding_charset): Remove vars that are set but not used.
19208 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
19209 that is set but not used.
19211 * print.c (print_object): Remove var that is set but not used.
19213 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
19214 The gnulib version avoids calling malloc in the usual case,
19215 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
19216 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
19217 * filelock.c (current_lock_owner): Likewise.
19218 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
19219 * sysdep.c: Include allocator.h, careadlinkat.h.
19220 (emacs_no_realloc_allocator): New static constant.
19221 (emacs_readlink): New function.
19222 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
19223 ../lib/careadlinkat.h.
19225 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
19227 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
19228 first non-nil return value).

19242 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
19243 and thereabouts. All callers changed.
19244 (get_per_char_metric): Remove parameter `f', unused since
19245 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
19247 2011-04-02 Jim Meyering <meyering@redhat.com>
19249 do not dereference NULL upon failed strdup
19250 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
19251 (ns_get_family): Likewise.
19253 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
19255 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
19257 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
19259 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
19262 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
19264 Add lexical binding.
19266 * window.c (Ftemp_output_buffer_show): New fun.
19267 (Fsave_window_excursion):
19268 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
19270 * lread.c (lisp_file_lexically_bound_p): New function.
19271 (Fload): Bind Qlexical_binding.
19272 (readevalloop): Remove `evalfun' arg.
19273 Bind Qinternal_interpreter_environment.
19274 (Feval_buffer): Bind Qlexical_binding.
19275 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
19277 (syms_of_lread): Declare `lexical-binding'.
19279 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
19281 * keyboard.c (eval_dyn): New fun.
19282 (menu_item_eval_property): Use it.
19284 * image.c (parse_image_spec): Use Ffunctionp.
19286 * fns.c (concat, mapcar1): Accept byte-code-functions.
19288 * eval.c (Fsetq): Handle lexical vars.
19289 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
19290 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
19291 (FletX, Flet): Obey lexical binding.
19292 (Fcommandp): Handle closures.
19293 (Feval): New `lexical' arg.
19294 (eval_sub): New function extracted from Feval. Use it almost
19295 everywhere where Feval was used. Look up vars in lexical env.
19297 (Ffunctionp): Move from subr.el.
19298 (Ffuncall): Handle closures.
19299 (apply_lambda): Remove `eval_flags'.
19300 (funcall_lambda): Handle closures and new byte-code-functions.
19301 (Fspecial_variable_p): New function.
19302 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
19303 but without exporting it to Lisp.
19305 * doc.c (Fdocumentation, store_function_docstring):
19306 * data.c (Finteractive_form): Handle closures.
19308 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
19311 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
19313 (exec_byte_code): New function extracted from Fbyte_code to handle new
19314 calling convention for byte-code-functions. Add new byte-codes.
19316 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
19318 * alloc.c (Fmake_symbol): Init new `declared_special' field.
19320 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
19322 * xdisp.c (redisplay_internal): Fix prototype.
19324 2011-03-31 Eli Zaretskii <eliz@gnu.org>
19326 * xdisp.c (SCROLL_LIMIT): New macro.
19327 (try_scrolling): Use it when setting scroll_limit.
19328 Limit scrolling to 100 screen lines.
19329 (redisplay_window): Even when falling back on "recentering",
19330 position point in the window according to scroll-conservatively,
19331 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
19333 (try_scrolling): When point is above the window, allow searching
19334 as far as scroll_max, or one screenful, to compute vertical
19335 distance from PT to the scroll margin position. This prevents
19336 try_scrolling from unnecessarily failing when
19337 scroll-conservatively is set to a value slightly larger than the
19338 window height. Clean up the case of PT below the margin at bottom
19339 of window: scroll_max can no longer be INT_MAX. When aggressive
19340 scrolling is in use, don't let point enter the opposite scroll
19341 margin as result of the scroll.
19342 (syms_of_xdisp) <scroll-conservatively>: Document the
19343 threshold of 100 lines for never-recentering scrolling.
19345 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
19347 * dispextern.h (move_it_by_lines):
19348 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused

19350 (message_log_check_duplicate): Remove parameters `prev_bol' and
19351 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
19352 (redisplay_internal): Remove parameter `preserve_echo_area',
19353 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
19355 * indent.c (Fvertical_motion):
19356 * window.c (window_scroll_pixel_based, Frecenter):
19357 Don't pass `need_y_p' to `move_it_by_lines'.
19359 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
19361 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
19362 steal a few bits to be more compact.
19363 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
19364 Remove unneeded casts.
19366 * bytecode.c (Fbyte_code): CAR and CDR can GC.
19368 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
19370 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
19371 binding" message (bug#7967).
19373 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
19375 Fix more problems found by GCC 4.6.0's static checks.
19377 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
19378 Remove unused local var.
19380 * editfns.c (Fmessage_box): Remove unused local var.
19382 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
19383 (note_mode_line_or_margin_highlight, note_mouse_highlight):
19384 Omit unused local vars.
19385 * window.c (shrink_windows): Omit unused local var.
19386 * menu.c (digest_single_submenu): Omit unused local var.
19387 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
19388 Omit unused local var.
19390 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
19391 Don't assume string length fits in int.
19392 (keyremap_step, read_key_sequence): Use size_t for sizes.
19393 (read_key_sequence): Don't check last_real_key_start redundantly.
19395 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
19396 instead of alloca (Bug#8344).
19398 * eval.c (Fbacktrace): Don't assume nargs fits in int.
19399 (Fbacktrace_frame): Don't assume nframes fits in int.
19401 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
19403 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
19406 * term.c (produce_glyphless_glyph): Remove unnecessary test.
19408 * cm.c (calccost): Turn while-do into do-while, for clarity.
19410 * keyboard.c (syms_of_keyboard): Use the same style as later
19411 in this function when indexing through an array. This also
19412 works around GCC bug 48267.
19414 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
19416 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
19418 * chartab.c (sub_char_table_ref_and_range): Redo for slight
19419 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
19421 * keyboard.c, keyboard.h (num_input_events): Now size_t.
19422 This avoids undefined behavior on integer overflow, and is a bit
19423 more convenient anyway since it is compared to a size_t variable.
19425 Variadic C functions now count arguments with size_t, not int.
19426 This avoids an unnecessary limitation on 64-bit machines, which
19427 caused (substring ...) to crash on large vectors (Bug#8344).

19437 * fns.c (concat): Likewise.
19438 * frame.c (x_set_frame_parameters): Likewise.
19439 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
19440 0 if not found, not -1. All callers changed.
19442 * alloc.c (garbage_collect): Don't assume stack size fits in int.
19443 (stack_copy_size): Now size_t, not int.
19444 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
19446 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
19448 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
19449 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
19450 All callers changed.
19452 * lisp.h (multibyte_char_to_unibyte):
19453 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
19454 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

19465 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
19466 don't set the hook to nil, but remove the offending function instead.
19467 (Qcommand_hook_internal): Remove, unused.
19468 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
19469 Vcommand_hook_internal.
19471 * eval.c (enum run_hooks_condition): Remove.
19472 (funcall_nil, funcall_not): New functions.
19473 (run_hook_with_args): Call each function through a `funcall' argument.

19487 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
19488 All callers changed.
19490 * w32.c (_wsa_errlist): Use braces for struct initializers.
19492 * xdisp.c (string_buffer_position_lim): Remove parameter `w',

19639 * term.c (Fsuspend_tty, Fresume_tty):
19640 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
19641 * window.c (temp_output_buffer_show):
19642 * insdel.c (signal_before_change):

19648 * callint.c (Fcall_interactively):
19649 * buffer.c (Fkill_all_local_variables):
19650 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
19652 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
19653 unconditionally since it does the check itself.
19655 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
19657 Fix more problems found by GCC 4.5.2's static checks.
19659 * coding.c (encode_coding_raw_text): Avoid unnecessary test
19660 the first time through the loop, since we know p0 < p1 then.
19661 This also avoids a gcc -Wstrict-overflow warning.
19663 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
19664 leading to a memory leak, possible in functions like
19665 load_charset_map_from_file that can allocate an unbounded number
19666 of objects (Bug#8318).
19668 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
19669 that could (at least in theory) be that large.
19671 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
19672 This is less likely to overflow, and avoids undefined behavior if
19673 overflow does occur. All callers changed. Use strtoul to scan
19674 for the unsigned long integer.
19675 (pint2hrstr): Simplify and tune code slightly.
19676 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

19686 * fileio.c (Fcopy_file): Report error if fchown or fchmod
19689 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
19691 * process.c (Fmake_network_process): Use socklen_t, not int,
19692 where POSIX says socklen_t is required in portable programs.
19693 This fixes a porting bug on hosts like 64-bit HP-UX, where
19694 socklen_t is wider than int (Bug#8277).
19695 (Fmake_network_process, server_accept_connection):
19696 (wait_reading_process_output, read_process_output):
19699 * process.c: Rename or move locals to avoid shadowing.

19709 Make tparam.h and terminfo.c consistent.
19710 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
19711 Include tparam.h instead, since it declares them.
19712 * cm.h (PC): Remove extern decl; tparam.h now does this.
19713 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
19714 * terminfo.c: Include tparam.h, to check interfaces.
19715 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
19716 (tparam): Adjust signature to match interface in tparam.h;
19717 this removes some undefined behavior. Check that outstring and len
19718 are zero, which they always are with Emacs.
19719 * tparam.h (PC, BC, UP): New extern decls.
19721 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
19722 (xftfont_open): Rename locals to avoid shadowing.

19739 (find_automatic_composition, composition_adjust_point): Likewise.
19740 (composition_update_it): Mark var as initialized.
19741 (find_automatic_composition): Mark vars as initialized,
19742 with a FIXME (Bug#8290).

19746 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
19747 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
19748 (BUF_DEC_POS): Be more systematic about renaming local temporaries
19749 to avoid shadowing.
19751 * textprop.c (property_change_between_p): Remove; unused.
19753 * intervals.c (interval_start_pos): Now static.
19755 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

19761 Fix pointer signedness.
19762 (alsa_choose_format): Remove unused local var.
19763 (wav_play): Initialize a variable to 0, to prevent undefined
19764 behavior (Bug#8278).
19766 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
19768 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
19770 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
19771 clobbering (Bug#8298).
19772 * sysdep.c (sys_subshell): Likewise.
19773 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
19775 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
19776 This should get cleaned up, so that child_setup has the
19777 same signature on all platforms.
19779 * callproc.c (call_process_cleanup): Now static.
19780 (relocate_fd): Rename locals to avoid shadowing.
19782 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
19784 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
19785 not to be necessary, and produces flickering.
19787 2011-03-20 Glenn Morris <rgm@gnu.org>
19789 * config.in: Remove file.
19791 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
19793 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
19794 are now in src/globals.h.
19795 (syms_of_minibuf): Remove spurious & from previous change.

19821 (sigchld_handler): Now static.
19823 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
19824 That way, the code declares only the vars that it needs.

19836 Define only if needed.
19838 * unexelf.c (unexec): Name an expression,
19839 to avoid gcc -Wbad-function-cast warning.
19840 Use a different way to cause a compilation error if anyone uses
19841 n rather than nn, a way that does not involve shadowing.
19842 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
19844 * deps.mk (unexalpha.o): Remove; unused.
19846 New file unexec.h, the (simple) interface for unexec (Bug#8267).

19968 (WORDCHAR_P): Likewise. This one is never needed, but is used

19999 New macros, so that the caller can use some names other than
20000 gcpro1, gcpro2, etc.
20001 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
20003 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
20004 argument, for consistency with GCPRO2_VAR, etc: it is now the
20005 prefix of the variable, not the variable itself. All uses
20007 * dired.c (directory_files_internal, file_name_completion):
20008 Rename locals to avoid shadowing.
20010 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
20011 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
20012 dired.c's scmp function, had undefined behavior.
20013 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
20014 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
20015 * buffer.h: ... to here, because these macros use current_buffer,
20016 and the new implementation with inline functions needs to have
20017 current_buffer in scope now, rather than later when the macros
20019 (downcase, upcase1): New static inline functions.
20020 (DOWNCASE, UPCASE1): Reimplement using these functions.
20021 This avoids undefined behavior in expressions like
20022 DOWNCASE (x) == DOWNCASE (y), which previously suffered
20023 from race conditions in accessing the global variables
20024 case_temp1 and case_temp2.
20025 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.

20052 so that gcc does not warn that these functions aren't declared.

20055 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
20056 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.

20062 * buffer.c (fix_overlays_before): Mark locals as initialized.
20063 (fix_start_end_in_overlays): Likewise. This function should be
20064 simplified by using pointers-to-pointers, but that's a different

20073 to suppress a gcc -Wclobbered warning that does not seem to be right.
20074 (MAXPATHLEN): Define only if needed.
20076 * process.c (serial_open, serial_configure): Move decls from here ...
20077 * systty.h: ... to here, so that they can be checked.
20079 * fns.c (get_random, seed_random): Move extern decls from here ...
20080 * lisp.h: ... to here, so that they can be checked.
20082 * sysdep.c (reset_io): Now static.
20083 (wait_for_termination_signal): Remove; unused.
20085 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

20090 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
20091 (describe_map_tree):
20092 Rename locals to avoid shadowing.
20094 * keyboard.c: Declare functions static if they are not used elsewhere.

20436 -Wuninitialized does not deduce are never used uninitialized.
20437 (detect_coding_iso_2022): Initialize a local variable that might
20438 be used uninitialized. Leave a FIXME because it's not clear that
20439 this initialization is needed. (Bug#8211)
