9 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
10 and mouse_face_hidden members to a bitfields.
11 * frame.h (struct frame): Remove set-but-not-used space_width member.
12 (FRAME_SPACE_WIDTH): Remove.

21 Don't let call-process be a zombie factory (Bug#12980).
22 Fixing this bug required some cleanup of the signal-handling code.
23 As a side effect, this change also fixes a longstanding rare race
24 condition whereby Emacs could mistakenly kill unrelated processes,
25 and it fixes a bug where a second C-g does not kill a recalcitrant
26 synchronous process in GNU/Linux and similar platforms.
27 The patch should also fix the last vestiges of Bug#9488,
28 a bug which has mostly been fixed on the trunk by other changes.
29 * callproc.c, process.h (synch_process_alive, synch_process_death)
30 (synch_process_termsig, sync_process_retcode):
31 Remove. All uses removed, to simplify analysis and so that
32 less consing is done inside critical sections.
33 * callproc.c (call_process_exited): Remove. All uses replaced
34 with !synch_process_pid.
35 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
36 These take the role of what used to be in unwind-protect arg.
38 (block_child_signal, unblock_child_signal):
39 New functions, to avoid races that could kill innocent-victim processes.
40 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
41 (call_process_kill): Record killed processes as deleted, so that
42 zombies do not clutter up the system. Do this inside a critical
43 section, to avoid a race that would allow the clutter.
44 (call_process_cleanup): Fix code so that the second C-g works again
45 on common platforms such as GNU/Linux.
46 (Fcall_process): Create the child process in a critical section,
47 to fix a race condition. If creating an asynchronous process,
48 record it as deleted so that zombies do not clutter up the system.
49 Do unwind-protect for WINDOWSNT too, as that's simpler in the
50 light of these changes. Omit unnecessary call to emacs_close
51 before failure, as the unwind-protect code does that.
52 * callproc.c (call_process_cleanup):
53 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
54 * process.c (record_deleted_pid): New function, containing
55 code refactored out of Fdelete_process.
56 (Fdelete_process): Use it.
57 (process_status_retrieved): Remove. All callers changed to use
59 (record_child_status_change): Remove, folding its contents into ...
60 (handle_child_signal): ... this signal handler. Now, this
61 function is purely a handler for SIGCHLD, and is not called after
62 a synchronous waitpid returns; the synchronous code is moved to
63 wait_for_termination. There is no need to worry about reaping
64 more than one child now.
65 * sysdep.c (get_child_status, child_status_changed): New functions.
66 (wait_for_termination): Now takes int * status and bool
67 interruptible arguments, too. Do not record child status change;
68 that's now the caller's responsibility. All callers changed.
69 Reimplement in terms of get_child_status.
70 (wait_for_termination_1, interruptible_wait_for_termination):
71 Remove. All callers changed to use wait_for_termination.
72 * syswait.h: Include <stdbool.h>, for bool.
73 (record_child_status_change, interruptible_wait_for_termination):
75 (record_deleted_pid, child_status_changed): New decls.
76 (wait_for_termination): Adjust to API changes noted above.
78 * bytecode.c, lisp.h (Qbytecode): Remove.
79 No longer needed after 2012-11-20 interactive-p changes.
81 2012-12-03 Eli Zaretskii <eliz@gnu.org>
83 * xdisp.c (redisplay_window): If the cursor is visible, but inside
84 the scroll margin, move point outside the margin. (Bug#13055)
86 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
88 * gtkutil.c (my_log_handler): New function.
89 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
91 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
93 * lisp.h (modify_region): Rename to...
94 (modify_region_1): ...new prototype.
95 * textprop.c (modify_region): Now static. Adjust users.
96 * insdel.c (modify_region): Rename to...
97 (modify_region_1): ...new function to work with current buffer.
98 Adjust comment and users. Use true and false for booleans.
100 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
102 * alloc.c (free_save_value): New function.
103 (safe_alloca_unwind): Use it.
104 * lisp.h (free_save_value): New prototype.
105 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
107 (save_excursion_restore): Adjust to match saved data structure.
108 Use free_save_value to offload some work from GC. Drop obsolete
111 2012-12-03 Chong Yidong <cyd@gnu.org>
113 * fileio.c (Vauto_save_list_file_name): Doc fix.
115 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
117 * w32fns.c: Remove prototype of atof.
118 (syspage_mask): Declared DWORD_PTR, for compatibility with 64-bit
120 (file_dialog_callback): Declared UINT_PTR.
122 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
125 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
126 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
129 2012-12-03 Glenn Morris <rgm@gnu.org>
131 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
133 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
135 Fix xpalloc confusion after memory is exhausted.
136 * alloc.c (xpalloc): Comment fix.
137 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
138 and signals an error, do not clear charset_table_size, as
139 charset_table is still valid.
140 * doprnt.c (evxprintf): Clear *BUF after freeing it.
142 Use execve to avoid need to munge environ (Bug#13054).
143 * callproc.c (Fcall_process):
144 * process.c (create_process):
145 Don't save and restore environ; no longer needed.
146 * callproc.c (child_setup):
147 Use execve, not execvp, to preserve environ.
149 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
151 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
153 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
155 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
156 display for sliced images (Bug#10500).
158 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
160 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
162 * doc.c (Fdocumentation): Re-add handling of function-documentation,
163 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
165 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
167 * xdisp.c (window_outdated): Remove eassert since it hits
168 some suspicious corner cases (see Bug#13007 and Bug#13012).
169 (mode_line_update_needed): New function.
170 (redisplay_internal, redisplay_window): Use it.
171 (ensure_selected_frame): New function.
172 (redisplay_internal, unwind_redisplay): Use it.
173 (redisplay_internal): Move comment about buffer_shared...
174 (buffer_shared_and_changed): ...near to its real use.
176 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
178 * callproc.c (Fcall_process): Don't misreport vfork failure.
180 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
182 * callproc.c (Fcall_process): Fix vfork portability problems.
183 Do not assume that fd[0], count, filefd, and save_environ survive
184 vfork. Fix bug whereby wrong errno value could be reported for
185 pipe failure. Some minor cleanups, too, as follows. Move buf and
186 bufsize to the context where they're needed. Change new_argv to
187 be of type char **, as this is more convenient and avoids casts.
188 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
189 Now local constants, not macros.
191 2012-11-18 Kenichi Handa <handa@gnu.org>
193 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
194 for the variable "f".
196 2012-11-13 Kenichi Handa <handa@gnu.org>
198 * font.c (font_unparse_xlfd): Exclude special characters from the
199 generating XLFD name.

241 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
242 between bpos_covered and bpos_max. This fixes cursor display when
243 several display strings follow each other.
245 * .gdbinit (pgx): If the glyph's object is a string, display the
246 pointer to string data, rather than the value of the string object
247 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
249 * indent.c (Fvertical_motion): If the starting position is covered
250 by a display string, return to one position before that, to avoid
251 overshooting it inside move_it_to. (Bug#12930)
253 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
255 * frame.h (struct frame): Remove display_preempted member

263 asked_for_visible and menubar_active members. Drop
264 unused pending_menu_activation member.
265 * xterm.h (struct x_output): Drop outdated #if 0 code.
266 Use bitfields for explicit_parent, asked_for_visible,
267 has_been_visible and net_wm_state_hidden_seen members.

272 of a literal "/". (Bug#12955)
273 (gl-stamp): Invoke fc.exe directly, not through cmd.
275 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>

278 * dired.c: Assume HAVE_DIRENT_H.
279 (NAMLEN): Remove, replacing with ...
280 (dirent_namelen): New function. All uses changed. Use the GNU macro
281 _D_EXACT_NAMELEN if available, as it's faster than strlen.
282 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
283 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
284 * makefile.w32-in (DIR_H): Remove. All uses replaced with
286 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
287 * ndir.h: Rename to ../nt/inc/dirent.h.

292 2012-11-23 Chong Yidong <cyd@gnu.org>
294 * xftfont.c (xftfont_open): Remove duplicate assignment.
296 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
298 * alloc.c (Fgarbage_collect): Unblock input after clearing
299 gc_in_progress to avoid note_mouse_highlight glitch with GC.
300 * frame.h (FRAME_MOUSE_UPDATE): New macro.
301 * msdos.c (IT_frame_up_to_date): Use it here...
302 * w32term.c (w32_frame_up_to_date): ...here...
303 * xterm.c (XTframe_up_to_date): ...and here...
304 * nsterm.m (ns_frame_up_to_date): ...but not here.
305 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
307 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):

313 (update_menu_bar, update_tool_bar): Use it to
314 simplify large 'if' statements.
315 (redisplay_internal): Generalize commonly used
316 'tail' and 'frame' local variables.
318 2012-11-22 Eli Zaretskii <eliz@gnu.org>
320 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
321 with Windows system header.
323 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
325 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
326 * alloc.c: Assume unistd.h exists.
327 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
328 * sysdep.c (get_current_dir_name): Assume getcwd exists.
329 (getwd) [USG]: Remove; no longer needed.

344 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
346 2012-11-21 Eli Zaretskii <eliz@gnu.org>
348 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
349 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
350 Define for the MSVC compiler.
352 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
354 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
355 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
356 dostounix_filename. Prevents crashes down the road, because
357 dostounix_filename assumes it gets a unibyte string. Reported by
358 Michel de Ruiter <michel@sentient.nl>, see
359 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
361 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>

384 (window_outdated): New function.
385 (text_outside_line_unchanged_p, redisplay_window): Use it.
386 (redisplay_internal): Likewise. Fix indentation.
388 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>

397 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
398 cygwin_convert_file_name*.

401 Rename cygwin_convert_path* to cygwin_convert_file_name*.
403 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
405 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
407 2012-11-18 Eli Zaretskii <eliz@gnu.org>
409 * w32select.c: Include w32common.h before w32term.h, so that
410 windows.h gets included before w32term.h uses some of its
413 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
415 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:

426 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
427 Needed following 2012-10-20 change. (Bug#12902)
429 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
431 * w32proc.c (waitpid): Remove unused label get_result.
433 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
435 * makefile.w32-in (SYSWAIT_H): New macro.
436 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
437 ($(BLD)/sysdep.$(O)): Update dependencies.
439 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
441 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
442 * callproc.c (relocate_fd): Assume F_DUPFD.
443 * emacs.c, term.c (O_RDWR): Remove.
444 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
445 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
446 * nsterm.m: Assume <fcntl.h> exists.
447 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
448 (create_pty, Fmake_network_process, server_accept_connection)
449 (wait_reading_process_output, init_process_emacs):
451 (wait_reading_process_output): Put in a special case for WINDOWSNT
452 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
453 It's not clear this is needed, but it's a more-conservative change.
454 (create_process): Assume FD_CLOEXEC.
455 (create_process, create_pty): Assume O_NOCTTY.
456 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
457 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
458 Omit if not DOS_NT, since F_GETFL is not defined there.
459 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
460 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
462 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
463 lack it, since gnulib guarantees this.
464 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
466 2012-11-17 Eli Zaretskii <eliz@gnu.org>
468 * w32.c (faccessat): Pretend that directories have the execute bit
469 set. Emacs expects that, e.g., in files.el:cd-absolute.
471 * w32proc.c (create_child): Don't clip the PID of the child
472 process to fit into an Emacs integer, as this is no longer a
474 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
475 reaping only the process specified by PID argument, if that is
476 positive. Use PID instead of dead_child to know which process to
477 reap. Wait for the child to die only if WNOHANG is not in
479 (sys_select): Don't set dead_child.
481 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
482 as it is no longer needed.
484 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
486 (record_child_status_change): Remove the setting of
487 record_at_most_one_child for the !WNOHANG case.
489 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
491 Fix problems in ns port found by static checking.
492 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
493 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
494 not to process group.
495 (ns_select): Use emacs_write, not write, as that's more robust
496 in the presence of signals.
497 (fd_handler:): Check for read errors.
499 2012-11-16 Glenn Morris <rgm@gnu.org>
501 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
503 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
505 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
507 2012-11-16 Eli Zaretskii <eliz@gnu.org>
509 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
510 use the same value of thread handle.
511 (start_timer_thread): If the timer thread exited (due to error),
512 clean up by closing the two handles it used. Duplicate the caller
513 thread's handle here, so it gets duplicated only once, when
514 launching the timer thread. Set priority of the timer thread, not
516 (getitimer): Don't duplicate the caller thread's handle here.
519 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
521 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
524 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
526 Remove no-longer-used pty_max_bytes variable.
527 * process.c (pty_max_bytes): Remove; unused.
528 (send_process): Do not set it.
530 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
532 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
535 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
537 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
538 This follows up on the 2012-09-29 patch that removed indirection
539 for the 'function' field. Reported by Sergey Vinokurov in
540 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
542 2012-11-14 Eli Zaretskii <eliz@gnu.org>
544 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
545 different name, as the MS runtime does not have such a function,
546 and probably never will.) All callers changed. Ignore DIRFD
547 value if PATH is an absolute file name, to match Posix spec
548 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
551 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
553 * xdisp.c (echo_area_display, redisplay_internal):
554 Omit redundant check whether frame_garbaged is set.
556 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
558 Use faccessat, not access, when checking file permissions (Bug#12632).
559 This fixes a bug that has been present in Emacs since its creation.
560 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
561 which must set some sort of record. (Torek's bug report was against
562 a predecessor of GNU Emacs, but GNU Emacs happened to have the
563 same common flaw.) See Torek's Usenet posting
564 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
565 Posted: Fri Apr 8 14:18:56 1983.
566 * Makefile.in (LIB_EACCESS): New macro.
568 * callproc.c (init_callproc):
569 * charset.c (init_charset):
570 * fileio.c (check_existing, check_executable, check_writable)
572 * lread.c (openp, load_path_check):
573 * process.c (allocate_pty):
575 Use effective UID when checking permissions, not real UID.
576 * callproc.c (init_callproc):
577 * charset.c (init_charset):
578 * lread.c (load_path_check, init_lread):
579 Test whether directories are accessible, not merely whether they exist.
580 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
581 * fileio.c (check_existing, check_executable, check_writable)
583 Use symbolic names instead of integers for the flags, as they're
585 (check_writable): New arg AMODE. All uses changed.
586 Set errno on failure.
587 (Ffile_readable_p): Use faccessat, not stat + open + close.
588 (Ffile_writable_p): No need to call check_existing + check_writable.
589 Just call check_writable and then look at errno. This saves a syscall.
590 dir should never be nil; replace an unnecessary runtime check
591 with an eassert. When checking the parent directory of a nonexistent
592 file, check that the directory is searchable as well as writable, as
593 we can't create files in unsearchable directories.
594 (file_directory_p): New function, which uses 'stat' on most platforms
595 but faccessat with D_OK (for efficiency) if WINDOWSNT.
596 (Ffile_directory_p, Fset_file_times): Use it.
597 (file_accessible_directory_p): New function, which uses a single
598 syscall for efficiency.
599 (Ffile_accessible_directory_p): Use it.
600 * xrdb.c (file_p): Use file_directory_p.
601 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
602 * lread.c (openp): When opening a file, use fstat rather than
603 stat, as that avoids a permissions race. When not opening a file,
604 use file_directory_p rather than stat.
605 (dir_warning): First arg is now a usage string, not a format.
606 Use errno. All uses changed.
607 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
608 that merely introduced a race.
609 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
610 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
611 and similarly for the other O_* flags.
612 * w32.c (sys_faccessat): Rename from sys_access and switch to
613 faccessat's API. All uses changed.
614 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
615 (magic_db): Rename from magic_file_p.
616 (magic_db, search_magic_path): Return an XrmDatabase rather than a
617 char *, so that we don't have to test for file existence
618 separately from opening the file for reading. This removes a race
619 fixes a permission-checking problem, and simplifies the code.
621 (file_p): Remove; no longer needed.
623 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
625 Omit glyphs initialization at startup.
626 * dispnew.c (glyphs_initialized_initially_p): Remove.
627 (adjust_frame_glyphs_initially): Likewise. Adjust users.
628 (Fredraw_frame): Move actual code from here...
629 (redraw_frame): ...to here. Add eassert. Adjust comment.
630 (Fredraw_display): Use redraw_frame.
631 * xdisp.c (clear_garbaged_frames): Likewise.
633 2012-11-13 Eli Zaretskii <eliz@gnu.org>
635 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
636 passed to pint2str and pint2hrstr to be at most the size of the
637 frame's decode_mode_spec_buffer. This avoids crashes with very
638 large values of FIELD_WIDTH argument to decode_mode_spec.
641 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
643 Fix a race with verify-visited-file-modtime (Bug#12863).
644 Since at least 1991 Emacs has ignored an mtime difference of no
645 more than one second, but my guess is that this was to work around
646 file system bugs that were fixed long ago. Since the race is
647 causing problems now, let's remove that code.
648 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
649 whose time stamp is off by no more than a second. Insist that the
650 file time stamps match exactly.
652 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
654 * frame.h (struct frame): Convert external_tool_bar member to
655 1-bit unsigned bitfield.
656 * termhooks.h (struct terminal): Remove mouse_moved member since
657 all users are long dead. Adjust comment on mouse_position_hook.
659 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
661 Simplify by using FOR_EACH_FRAME here and there.
662 * frame.c (next_frame, prev_frame, other_visible_frames)
663 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
664 * w32term.c (x_window_to_scroll_bar): Likewise.
665 * window.c (window_list): Likewise.
666 * xdisp.c (x_consider_frame_title): Likewise.
667 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
668 * xfns.c (x_window_to_frame, x_any_window_to_frame)
669 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
670 * xmenu.c (menubar_id_to_frame): Likewise.
671 * xselect.c (frame_for_x_selection): Likewise.
672 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
673 (x_window_to_menu_bar): Likewise.
674 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
676 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
678 * data.c (Qdefalias_fset_function): Now static.
680 Another tweak to vectorlike_header change.
681 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
682 Remove, and replace all uses with ...
683 (next_in_free_list, set_next_in_free_list):
684 New functions, which respect C's aliasing rules better.
686 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
688 * window.c (list4i): Rename from 'quad'. All uses changed.
689 Needed because <sys/types.h> defines 'quad' on Solaris 10.
691 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
693 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
694 warning about mixing declarations and code in ISO C90.
696 2012-11-10 Martin Rudalics <rudalics@gmx.at>
698 * window.c (Fsplit_window_internal): Set combination limit of
699 new parent window to t iff Vwindow_combination_limit is t;
700 fixing a regression introduced with the change from 2012-09-22.
701 (Fset_window_combination_limit): Fix doc-string.
703 2012-11-10 Eli Zaretskii <eliz@gnu.org>
705 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
706 amount when the scroll margins are too large. When scrolling
707 backwards in the buffer, give up if cannot reach point or the
708 scroll margin within a reasonable number of screen lines.
709 Fixes point position in window under scroll-up/down-aggressively when
710 point is positioned many lines beyond the window top/bottom.
713 * ralloc.c (relinquish): If real_morecore fails to return memory
714 to the system, don't crash; instead, leave the last heap
715 unchanged and return. (Bug#12774)
717 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
719 * lisp.h (AUTOLOADP): New macro.
720 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
721 * data.c (Ffset): Remove special ad-advice-info handling.
722 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
724 (Finteractive_form): Simplify.
725 (Fquo): Don't insist on having at least 2 arguments.
726 (Qdefalias_fset_function): New var.
728 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
730 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
732 * nsfont.m (Qcondensed, Qexpanded): New variables.
733 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
734 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
736 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
738 Fix recently introduced crash on MS-Windows (Bug#12839).
739 * w32term.h (struct scroll_bar): Use convenient header.
740 (SCROLL_BAR_VEC_SIZE): Remove.
741 * w32term.c (x_scroll_bar_create): Use VECSIZE.
743 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
745 Tweak last vectorlike_header change.
746 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
747 vectorlike object on the free list. This is introduced to avoid
748 some (but not all) pointer casting and aliasing problems, see
749 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
750 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
752 (xvectype, xvecsize): Use them to examine Lisp_Object values.
754 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
756 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
757 been removed, so remove them here also.
759 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
761 * doc.c (Fdocumentation): Handle new property
762 dynamic-docstring-function to replace the old ad-advice-info.
764 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
766 * fns.c (Qeql, hashtest_eq): Now static.
768 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
770 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
771 * fns.c (hashfn_eq, hashfn_eql, sxhash):
772 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
773 * buffer.c (compare_overlays): Use XLI rather than XHASH.
775 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
777 Use same hash function for hashfn_profiler as for hash_string etc.
778 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
779 * lisp.h (sxhash_combine): New inline function, with the contents
780 of the old SXHASH_COMBINE.
781 * profiler.c (hashfn_profiler): Use it, instead of having a
782 special hash function containing a comparison that always yields 1.
784 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
786 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
787 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
788 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
791 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
793 * image.c (xpm_make_color_table_h): Fix compiler error because
794 make_hash_table changed.
796 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
798 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
800 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
802 Use ad-hoc comparison function for the profiler's hash-tables.
803 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
804 (make_log): Use them.
805 (handle_profiler_signal): Don't inhibit quit any longer since we don't
806 call Fequal any more.
807 (Ffunction_equal): New function.
808 (cmpfn_profiler, hashfn_profiler): New functions.
809 (syms_of_profiler): Initialize them.
810 * lisp.h (struct hash_table_test): New struct.

812 * alloc.c (mark_object): Mark hash_table_test fields of hash tables.
813 * fns.c (make_hash_table): Take a struct to describe the test.
814 (cmpfn_eql, cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
815 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
816 (hash_lookup, hash_remove_from_table): Move assertion checking of
817 hashfn result here. Check hash-equality before calling cmpfn.

819 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.
820 (syms_of_fns): Initialize them.

830 value of w32-scroll-lock-modifier is neither nil nor one of the
831 known key modifiers. (Bug#12806)
833 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
835 Shrink struct vectorlike_header to the only size field.
836 * lisp.h (enum pvec_type): Avoid explicit enum member values.
838 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
839 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
840 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
841 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
842 information from the vector header. Adjust comment.

852 (enum mem_type): Adjust comment.
853 (NEXT_IN_FREE_LIST): New macro.
854 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
855 (Fmake_bool_vector): Likewise.
856 (struct large_vector): New type to represent allocation unit for
857 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
858 (large_vectors): Change type to struct large_vector.
859 (allocate_vector_from_block): Simplify.
860 (PSEUDOVECTOR_NBYTES): Replace with...
861 (vector_nbytes): ...new function. Adjust users.
862 (sweep_vectors): Adjust processing of large vectors.
863 (allocate_vectorlike): Likewise.
864 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
865 Add easserts. Adjust XSETPVECTYPESIZE usage.
866 (allocate_buffer): Use BUFFER_PVEC_INIT.
867 (live_vector_p): Adjust to match large vector.
868 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
869 * buffer.h (struct buffer): Add next member.
870 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
872 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
873 * fns.c (internal_equal): Adjust to match enum pvec_type change.

878 (xvecsize): New command.
880 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
882 * keyboard.c (event_to_kboard): Do not dereference
883 frame_or_window field of SELECTION_REQUEST_EVENT
884 and SELECTION_CLEAR_EVENT events (Bug#12814).
885 * xterm.h (struct selection_input_event): Adjust comment.
887 2012-11-07 Eli Zaretskii <eliz@gnu.org>
889 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
890 such as Scroll Lock, if the respective keys are treated as
891 function keys, not as modifiers. This avoids destroying non-ASCII
892 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
894 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
896 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
898 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
900 Restore some duplicate definitions (Bug#12814).
901 This undoes part of the 2012-11-03 changes. Some people build
902 with plain -g rather than with -g3, and they need the duplicate
903 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
904 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
905 Define as macros, as well as as enums or as constants.
907 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
909 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
910 to keypad keys (Bug#12816).
912 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
914 Minor adjustments of recently-changed frame functions.
915 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
916 known to be a frame (we're in the FRAMEP branch).
917 * lisp.h (Qframep): Remove decl. frame.h declares this.
918 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
919 since they're meant for Lisp fixnum values.
921 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
923 * window.c (Fwindow_combination_limit): Revert to the only
924 required argument and adjust docstring as suggested in
925 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
926 by Martin Rudalics <rudalics@gmx.at>.
928 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
930 Widely used frame validity and checking functions.
931 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.

935 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
936 (Fframe_pointer_visible_p): Use decode_any_frame.
937 (Fmake_frame_visible, Fmake_frame_invisible, Ficonify_frame)
938 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
939 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
940 (Fframe_focus): Likewise. Allow zero number of arguments.
942 (frame_buffer_list, frame_buffer_predicate): Remove.
943 * lisp.h (frame_buffer_predicate): Remove prototype.
944 * buffer.c (Fother_buffer): Use decode_any_frame.
945 * xdisp.c (Ftool_bar_lines_needed): Likewise.
946 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
947 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
948 (Fclose_font, Ffont_info): Use decode_live_frame.
949 * fontset.c (check_fontset_name): Likewise.
950 * terminal.c (Fframe_terminal): Likewise.
951 * w32fns.c (check_x_frame): Likewise.
952 * window.c (Fminibuffer_window, Fwindow_at)
953 (Fcurrent_window_configuration): Likewise.
954 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
955 Likewise. Allow zero number of arguments. Adjust docstring.
956 * dispnew.c (Fredraw_frame): Likewise.
957 * xfaces.c (frame_or_selected_frame): Remove.
958 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
959 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
960 (Fframe_face_alist): Use decode_live_frame.
961 * xfns.c (check_x_frame): Likewise.
963 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
965 * window.c (quad): New function.
966 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
967 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
968 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
969 (Fwindow_line_height): Use it.
970 (Fwindow_fringes): Use list3.
971 (Fwindow_scroll_bars): Use list4.
972 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
973 (Fwindow_combination_limit): Allow zero number of arguments.
975 2012-11-05 Eli Zaretskii <eliz@gnu.org>
977 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
979 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
980 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
981 file descriptor 2 for standard error. (Bug#12805)
983 2012-11-05 Chong Yidong <cyd@gnu.org>
985 * process.c (wait_reading_process_output): Revert previous change.
987 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
989 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
990 This removes code that has been obsolete since around 1990.
991 * callproc.c (Fcall_process):
993 * process.c (create_process):
994 * term.c (dissociate_if_controlling_tty):
995 Assume setsid exists.
996 * callproc.c (child_setup): Assume setpgid exists and behaves as
997 per POSIX.1-1988 or later.
998 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
999 * emacs.c (shut_down_emacs):
1000 * sysdep.c (sys_suspend, init_foreground_group):
1001 Assume getpgrp behaves as per POSIX.1-1998 or later.
1002 * msdos.c (setpgrp): Remove.
1003 (tcgetpgrp, setpgid, setsid): New functions.
1004 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
1005 * term.c (no_controlling_tty): Remove; unused.
1006 * w32proc.c (setpgrp): Remove.
1007 (setsid, tcgetpgrp): New functions.
1009 Simplify by assuming __fpending.
1010 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
1011 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
1012 Do not assume that __fpending's result fits in int.
1014 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
1016 Remove EMACS_OUTQSIZE+sleep hack.
1017 * dispnew.c (update_frame_1): Remove hack for terminals slower
1018 than 2400 bps, which throttled Emacs by having it sleep.
1019 This code hasn't worked since at least 2007, when the multi-tty stuff
1020 was added, and anyway those old terminals are long dead.
1021 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
1022 without the dispnew.c change, as dispnew.c doesn't include systty.h.
1024 Fix data-loss with --version (Bug#9574).
1025 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
1026 as we can't assume that emacs_strerror is initialized, and strerror
1027 is good enough here.
1028 (main): Invoke atexit earlier, to catch earlier instances of
1029 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
1031 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
1033 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
1034 (keyDown): Remap keypad keys to X11 virtual key codes.
1036 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
1038 Fix data-loss with --batch (Bug#9574).
1039 * emacs.c: Include <close-stream.h>.
1040 (close_output_streams): New function.
1041 (main): Pass it to atexit, so that Emacs closes stdout and stderr
1042 and handles errors appropriately.
1043 (Fkill_emacs): Don't worry about flushing, as close_output_stream
1046 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
1047 The symptom is a diagnostic "GLib-WARNING **: In call to
1048 g_spawn_sync(), exit status of a child process was requested but
1049 SIGCHLD action was set to SIG_IGN and ECHILD was received by
1050 waitpid(), so exit status can't be returned." The diagnostic
1051 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
1052 The real bug is a race condition between Emacs and glib: Emacs
1053 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
1054 so that glib can't find it. Work around the bug by invoking
1055 waitpid only on subprocesses that Emacs itself creates.
1056 * process.c (create_process, record_child_status_change):
1057 Don't use special value -1 in pid field, as the caller now must
1058 know the pid rather than having the callee infer it.
1059 The inference was sometimes incorrect anyway, due to another race.
1060 (create_process): Set new 'alive' member if child is created.
1061 (process_status_retrieved): New function.
1062 (record_child_status_change): Use it.
1063 Accept negative 1st argument, which means to wait for the
1064 processes that Emacs already knows about. Move special-case code
1065 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
1066 processes that have already been waited for, by testing and
1067 clearing new 'alive' member.
1068 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
1069 now does this internally.
1070 (handle_child_signal): Let record_child_status_change do all
1071 the work, since we do not want to reap all exited child processes,
1072 only the child processes that Emacs itself created.
1073 * process.h (Lisp_Process): New boolean member 'alive'.
1075 Omit duplicate definitions no longer needed with gcc -g3.
1076 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
1077 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
1078 Define only as macros. There's no longer any need to also define
1079 these symbols as enums or as constants, since we now assume
1080 gcc -g3 when debugging.
1082 2012-11-03 Eli Zaretskii <eliz@gnu.org>
1084 * lisp.mk: Adjust comments to the fact that term/internal is now
1085 loaded from loadup.el.
1087 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
1088 (msdos_fatal_signal): New function.
1089 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
1092 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
1093 for GCC versions before 4.
1094 (emacs_raise): Define to call msdos_fatal_signal.
1096 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
1097 iterator when starting in the middle of a display or overlay
1100 2012-11-03 Chong Yidong <cyd@gnu.org>
1102 * process.c (wait_reading_process_output): Clean up the last
1105 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
1107 * process.c (wait_reading_process_output): Avoid a race condition
1108 with SIGIO delivery (Bug#11536).
1110 2012-11-03 Chong Yidong <cyd@gnu.org>
1112 * buffer.c (cursor_type): Untabify docstring.
1114 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1116 * frame.h (struct frame): Drop can_have_scroll_bars member
1117 which is meaningless for a long time. Adjust comments.
1118 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
1119 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
1121 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1123 * window.c (decode_next_window_args): Update window arg after
1124 calling decode_live_window and so fix crash reported at
1125 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
1126 by Juanma Barranquero <lekktu@gmail.com>.
1127 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
1128 * font.c (Ffont_at): Likewise.
1130 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
1132 * widget.c (resize_cb): New function.
1133 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
1134 (EmacsFrameResize): Check if all is up to date before changing frame
1137 2012-11-02 Eli Zaretskii <eliz@gnu.org>
1139 Implement backtrace output for fatal errors on MS-Windows.
1140 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
1141 (BACKTRACE_LIMIT_MAX): New macro.
1142 (w32_backtrace): New function.
1143 (emacs_abort): Use w32_backtrace when the user chooses not to
1144 attach a debugger. Update the text of the abort dialog.
1146 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1148 Window-related stuff cleanup here and there.
1149 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
1150 Use decode_any_window.
1151 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
1152 * xdisp.c (Fformat_mode_line): Likewise.
1153 * font.c (Ffont_at): Use decode_live_window.
1154 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
1155 * window.c (decode_next_window_args): Likewise.
1156 (decode_any_window): Remove static.
1157 * window.h (decode_any_window): Add prototype.
1158 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
1159 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
1162 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1164 Remove pad from struct input_event.
1165 * termhooks.h (struct input_event): Remove padding field.
1167 * keyboard.c (event_to_kboard): Simplify because frame_or_window
1168 member is never cons for a long time. Adjust comment.
1169 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
1170 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
1171 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
1172 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
1174 2012-11-01 Eli Zaretskii <eliz@gnu.org>
1176 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
1178 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
1180 Fix crash when using Emacs as commit editor for git (Bug#12697).
1181 * callproc.c (setpgrp): Remove macro, as we now use setpgid
1182 and it is configured in conf_post.h.
1183 (Fcall_process): Don't invoke both setsid and setpgid; the former
1184 is enough, if it exists.
1185 * callproc.c (Fcall_process, child_setup):
1186 * process.c (create_process): Use setpgid.
1187 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
1189 * dispnew.c (init_display): Initialize the foreground group
1190 if we are running a tty display.
1191 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
1192 * lisp.h (init_foreground_group): New decl.
1193 * sysdep.c (inherited_pgroup): New static var.
1194 (init_foreground_group, tcsetpgrp_without_stopping)
1195 (narrow_foreground_group, widen_foreground_group): New functions.
1196 (init_sys_modes): Narrow foreground group.
1197 (reset_sys_modes): Widen foreground group.
1199 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
1201 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
1203 2012-10-31 Martin Rudalics <rudalics@gmx.at>
1205 * minibuf.c (read_minibuf): Restore current buffer since
1206 choose_minibuf_frame calling Fset_frame_selected_window may
1207 change it (Bug#12766).
1209 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
1211 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
1213 2012-10-30 Kenichi Handa <handa@gnu.org>
1215 * font.c (Ffont_at): If WINDOW is specified and it is not
1216 displaying the current buffer, signal an error.
1218 2012-10-29 Daniel Colascione <dancol@dancol.org>
1220 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
1221 In preparation for fixing bug#12739, move these functions from
1224 * coding.h, coding.c: ... to here, and compile them only when
1225 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
1226 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
1228 2012-10-28 Eli Zaretskii <eliz@gnu.org>
1230 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
1231 (timer_loop, getitimer, setitimer): Use it instead of
1232 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
1234 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
1237 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
1239 * nsterm.m (NO_APPDEFINED_DATA): New define.
1240 (last_appdefined_event_data): New variable
1241 (last_appdefined_event): Remove.
1242 (ns_select): Initialize t from last_appdefined_event_data instead
1243 of [last_appdefined_event data1].
1244 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
1245 remove last_appdefined_event (Bug#12698).
1247 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
1249 * frame.c (x_set_font): Catch internal error.
1251 2012-10-27 Eli Zaretskii <eliz@gnu.org>
1253 Avoid overflow in w32 implementation of interval timers.
1254 When possible, for ITIMER_PROF count only times the main thread
1256 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
1257 'volatile ULONGLONG' types. All the other data which was
1258 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
1259 (GetThreadTimes_Proc): New typedef.
1260 (w32_get_timer_time): New function, returns a suitable time value
1262 (timer_loop): Enter critical section when accessing ULONGLONG
1263 values of the itimer_data struct, as these accesses are no longer
1264 atomic. Call 'w32_get_timer_time' instead of 'clock'.
1265 Remove unused variable.
1266 (init_timers): Initialize s_pfn_Get_Thread_Times.
1267 (start_timer_thread): Don't assign itimer->caller_thread here.
1268 (getitimer): Assign itimer->caller_thread here.
1269 (setitimer): Always call getitimer to get the value of ticks_now.
1270 (sys_spawnve): Avoid compiler warning about format mismatch.
1272 2012-10-26 Eli Zaretskii <eliz@gnu.org>
1274 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
1275 mouse movement events if the menu bar is active. This avoids
1276 producing a busy "hour-glass" cursor by Windows if the mouse
1277 pointer is positioned over a tooltip shown for some menu item.
1279 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
1281 Don't assume process IDs fit in int.
1282 * emacs.c (shut_down_emacs) [!DOS_NT]:
1283 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
1284 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
1285 Use pid_t, not int, to store process IDs, as 'int'
1286 is not wide enough on a few platforms (e.g., AIX and IRIX).
1288 2012-10-23 Kenichi Handa <handa@gnu.org>
1290 The following change is to make face-font-rescale-alist work
1291 correctly for non-ASCII fonts.
1293 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
1294 (font_open_for_lface): Handle Vface_font_rescale_alist.
1296 2012-10-23 Chong Yidong <cyd@gnu.org>
1298 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
1300 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
1302 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
1304 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
1306 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
1309 2012-10-21 Glenn Morris <rgm@gnu.org>
1311 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
1313 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
1315 Port to OpenBSD 5.1.
1316 * frame.c (Fmouse_position, Fmouse_pixel_position):
1317 * xdisp.c (produce_stretch_glyph):
1318 Declare local vars only when they're needed.
1319 This is clearer and avoids a warning on OpenBSD about unused vars.
1320 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
1321 This is safer, and avoids OpenBSD warnings about unused vars.
1322 * keyboard.c (record_menu_key): Remove unnecessary decl.
1323 (poll_timer): Define only if POLL_FOR_INPUT is defined.
1324 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
1325 as our definition clashes with OpenBSD's.
1326 * xfaces.c (load_face_colors, check_lface_attrs)
1327 (get_lface_attributes_no_remap, get_lface_attributes)
1328 (lface_fully_specified_p, x_supports_face_attributes_p)
1329 (tty_supports_face_attributes_p, face_fontset, realize_face)
1330 (realize_x_face, realize_tty_face):
1331 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
1332 merely Lisp_Object *. This is more informative and avoids
1333 a warning on OpenBSD about accessing beyond an object's size.
1335 2012-10-20 Chong Yidong <cyd@gnu.org>
1337 * lread.c (Fload): Doc fix (Bug#12592).
1339 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
1341 * font.c (Ffont_at): Fix previous change.
1343 2012-10-19 Eli Zaretskii <eliz@gnu.org>
1345 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
1346 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
1349 * alloc.c (NSTATICS): Decrease to 0x800.
1351 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>
1353 * fns.c (Fnreverse): Include the problem element when signalling an
1356 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
1358 * nsterm.m (ns_select): Check writefds before call to
1359 FD_ISSET (Bug#12668).
1361 2012-10-18 Daniel Colascione <dancol@dancol.org>
1363 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
1364 (staticpro): If we run out of staticpro slots, die with an
1365 informative error instead of just calling emacs_abort.
1367 2012-10-18 Martin Rudalics <rudalics@gmx.at>
1369 Fix two flaws reported by Dmitry Antipov.
1370 * window.c (Ftemp_output_buffer_show): Remove.
1371 (Fwindow_vscroll, Fset_window_vscroll): Use decode_live_window.
1372 (syms_of_window): Remove defsubr for Stemp_output_buffer_show.
1374 2012-10-17 Eli Zaretskii <eliz@gnu.org>
1376 * makefile.w32-in ($(BLD)/w32.$(O)):
1377 ($(BLD)/vm-limit.$(O)):
1379 ($(BLD)/unexw32.$(O)):
1380 ($(BLD)/fileio.$(O)):
1381 ($(BLD)/dispnew.$(O)): Update dependencies.
1383 * w32term.h (w32_initialize_display_info, initialize_w32_display):
1386 * w32proc.c: Include ctype.h.
1388 * w32.h (init_environment, check_windows_init_file)
1389 (syms_of_ntproc, syms_of_ntterm, dostounix_filename)
1390 (unixtodos_filename, init_winsock, srandom, random, sys_pipe)
1391 (set_process_dir, sys_spawnve, register_child, sys_sleep, getwd)
1392 (sys_link): Add prototypes.
1394 * w32.c: Include w32select.h.
1395 (sys_access, e_malloc, sys_select): Add prototypes.
1396 (emacs_gnutls_pull): 'timeout' is now EMACS_TIME, not struct timeval.
1398 * vm-limit.c [WINDOWSNT]: Include w32heap.h.
1400 * unexw32.c: Include lisp.h and w32.h.
1402 * term.c [WINDOWSNT]: Include w32term.h.
1404 * process.c [WINDOWSNT]: Add prototype of sys_select.

1466 * image.c (init_tiff_functions, init_imagemagick_functions)
1467 (init_svg_functions): Fix cygw32 build break by using these
1468 functions only when WINDOWSNT _and_ HAVE_NTGUI.

1489 Fix some stat-related races.
1490 * fileio.c (Fwrite_region): Avoid race condition if a file is

1523 * fileio.c (check_existing): New function.
1524 (make_temp_name, Ffile_exists_p, Ffile_writable_p): Call it
1525 instead of calling 'stat', when what's needed is to check whether
1526 a file exists. This avoids expensive system calls on MS-Windows.
1529 * w32.c (init_environment): Call 'check_existing' instead of 'stat'.
1531 * lread.c (openp) [WINDOWSNT]: Call 'access' instead of 'stat' to

1621 (detect_input_pending_run_timers):
1622 * process.c (wait_reading_process_output):
1623 Use unsigned for counter where wraparound-on-overflow is desired,
1624 since unsigned is guaranteed to have that behavior and signed is not.
1625 (read_char): Use ptrdiff_t for string length.
1626 (get_input_pending): Remove first argument, since it was always
1627 the same pointer-to-int (now pointer-to-boolean) &input_pending,
1628 and behave as if it had that value. Return new value of
1629 input_pending. All callers changed.
1630 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
1631 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
1633 * keymap.c (push_key_description): Omit last arg, which was always 1.
1634 All callers changed.
1636 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.
1638 2012-10-10 Juanma Barranquero <lekktu@gmail.com>

1654 Don't include termopts.h.
1656 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
1658 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
1660 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
1662 * commands.h (immediate_quit): Remove duplicate decl.
1664 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
1666 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles

1669 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
1671 2012-10-09 Eli Zaretskii <eliz@gnu.org>
1673 * w32fns.c (w32_last_error): Change the return value to DWORD, to
1674 match what GetLastError returns. Explain why the function is
1677 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
1678 'is_tooltip_frame', to avoid confusion with its global namesake.
1680 2012-10-08 Daniel Colascione <dancol@dancol.org>
1682 * xdisp.c (start_hourglass): Call w32_note_current_window when
1683 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
1684 build that caused Emacs to display the hourglass cursor forever.
1686 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
1687 which is broken under remote desktop, calculate the number of
1688 colors available for a display based on the display's number of
1689 planes and number of bits per pixel per plane. (bug#10397).
1691 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
1693 * nsfont.m (Vfonts_in_cache): New variable.
1694 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
1695 are used. Add cached fonts to Vfonts_in_cache.
1696 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
1698 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
1700 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
1702 (FONT_H): Define after FRAME_H.
1703 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
1704 Update dependencies.
1706 * w32term.c: Remove leftover declaration of keyboard_codepage.
1708 2012-10-08 Eli Zaretskii <eliz@gnu.org>
1710 * makefile.w32-in (FONT_H): Add $(FRAME_H).
1711 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
1712 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
1713 (GLOBAL_SOURCES): Add cygw32.c.
1714 ($(BLD)/unexw32.$(O)):
1716 ($(BLD)/w32console.$(O)):
1717 ($(BLD)/w32fns.$(O)):
1718 ($(BLD)/w32heap.$(O)):
1719 ($(BLD)/w32menu.$(O)):
1720 ($(BLD)/w32proc.$(O)): Add w32common.h.
1722 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
1724 (x_to_w32_color): Don't modify the argument, modify a copy instead.
1726 2012-10-08 Daniel Colascione <dancol@dancol.org>
1728 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
1729 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
1730 accidental message numbering hole. Change other messages to
1733 * w32select.h (HAVE_W32SELECT): Remove.
1735 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
1736 w32common.h instead of w32heap.h.
1738 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
1739 (get_allocation_unit, get_processor_type, get_w32_major_version)
1740 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
1741 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
1742 (OS_NT, os_subtype, cache_system_info): Move declarations to
1745 * w32heap.c: Include w32common.h.
1746 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
1747 (w32_minor_version, w32_build_number, w32_subtype):
1748 Remove duplicate definitions.
1750 * w32fns.c: Include w32common.h; include w32heap.h only in
1753 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
1754 Use `report_file_error' instead of `error' in order to better
1755 inform users of what went wrong. Increase NTGUI_UNICODE file
1756 dialog box file name length to 32k, the maximum allowed by the NT
1759 * w32common.h: New file.
1760 (ROUND_UP, ROUND_DOWN, get_page_size)
1761 (get_allocation_unit, get_processor_type, get_w32_major_version)
1762 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
1763 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
1764 (OS_NT, os_subtype, cache_system_info): Move here.
1766 * unexw32.c, unexcw.c: Include w32common.h.
1768 * emacs.c (main): Use (defined (WINDOWSNT) || defined
1769 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
1770 to call syms_of_w32select.
1772 * cygw32.h: Remove obsolete EXFUN declarations.
1774 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.

1777 of w32inevt.o from SOME_MACHINE_OBJECTS.
1779 2012-10-08 Daniel Colascione <dancol@dancol.org>
1781 * image.c: Permanent fix for JPEG compilation issue --- limit
1782 jpeglib `boolean' redefinition to Cygwin builds.
1784 2012-10-08 Eli Zaretskii <eliz@gnu.org>
1786 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
1788 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
1791 2012-10-08 Daniel Colascione <dancol@dancol.org>
1793 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
1794 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
1795 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
1796 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
1797 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
1798 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
1799 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
1800 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
1801 now a supported configuration.
1803 * Makefile.in: consolidate image variables into LIBIMAGE; add
1804 W32_OBJ and W32_LIBS. Compile new files.
1807 (_DebPrint) declare tracing facility for W32 debugging. We need
1808 to unify tracing later.
1810 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
1811 unconditional use of W32 Unicode functions. Cygwin runs only on
1812 100% Unicode operating systems.
1814 * cygw32.c: New file. Define Cygwin-specific facilities.
1815 (Fcygwin_convert_path_to_windows)
1816 (Fcygwin_convert_path_from_windows): New user functions for
1817 accessing Cygwin path-munging routines.
1819 * cygw32.h: New file.
1820 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
1821 UTF-16LE strings temporarily inside non-Lisp-visible string
1824 (w32_strerror): Just what it says on the tin.
1826 * emacs.c: Make the NS fork-then-exec code for daemon-launching
1827 also run for Cygwin; both systems have the same problem with using
1828 GUI facilities in a forked child. Also call syms_of_cygw32,
1829 syms_of_w32select in correct places.
1831 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
1832 needs fork-then-exec for daemon launching.
1834 * font.h: Include frame.h.
1836 * image.c: Use the image library cache machinery only when we're
1837 compiling for native WINDOWSNT; Cygwin can use shared libraries
1838 like any other Unixlike system.
1840 * keyboard.c: Clarify a comment regarding the input loop.
1842 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
1843 functions directly instead of trying to detect at runtime that our
1844 host operating system supports them. We make this change for two
1845 reasons: Cygwin lacks support for the multibyte character
1846 conversion functions used by the legacy menu code, and Cygwin
1847 never needs to rely on non-Unicode APIs.
1849 * unexw32.c (hinst): Declare extern.
1851 * w32.c: Change header order;
1852 (w32_strerror): Move to w32fns.c because we need it for
1853 non-WINDOWSNT builds.
1855 * w32.h: Add #error macro to make sure we don't include w32.h for
1856 Cygwin builds. Remove w32select declarations.
1858 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
1859 w32fns.c. w32console.c is WINDOWSNT-only.
1861 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
1862 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
1864 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
1865 (w32_major_version, w32_minor_version, w32_build_number)
1866 (os_subtype, sound_type): Define here
1867 (w32_defined_color): Make color parameter const for consistency
1868 with other _defined_color functions.
1869 (w32_createwindow): Unconditionally call w32_init_class instead of
1870 doing so only when hprevinst is non-NULL. Plumbing hprevinst
1871 through the code is complex and unnecessary because class
1872 registration is practically free.
1873 (w32_name_of_message): New EMACSDEBUG-only function.
1874 (Fset_message_beep): Move here
1875 (Fx_open_connection): Require that the display name for Windows be
1876 "w32" for consistency, emacsclient disambiguation, and maybe, one
1877 day, multi-window-system support.
1878 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
1879 Cygwin files for W32 GUI facilities, since these clearly don't

1905 descriptor the system used to tell us about pending thread
1908 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
1909 that prevented compilation under non-WINDOWSNT systems.

1916 (prepend_msg, w32_message_fd): Declare globally.
1919 (keyboard_handle): Use only when WINDOWSNT.
1920 (notify_msg_ready): New function. Posts a message to the main
1921 thread's message queue under CYGWIN, which wakes up the main
1922 thread from select(2) by making the /dev/windows file descriptor
1923 ready. Under WINDOWSNT, it sets an event the same way the old
1926 (post, prepend_msg): Actually call notify_msg_ready instead of
1927 setting the input event directly.
1929 2012-10-07 Eli Zaretskii <eliz@gnu.org>
1931 * ralloc.c (relinquish): If a heap is ready to be relinquished,
1932 but it still has blocs in it, don't return it to the system,
1933 instead of aborting. (Bug#12402)
1935 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>

1972 defined as a macro, as is done in Solaris.
1973 (sys_siglist_entries): New macro.
1974 (save_strsignal): Use it.
1975 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
1976 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
1978 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
1980 * nsfns.m (Fx_create_frame): Call x_default_parameter with
1981 fullscreen/Fullscreen.
1983 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
1984 tobar_height is new.
1986 * nsterm.m (x_make_frame_visible): Check for fullscreen.
1987 (ns_fullscreen_hook): Activate old style fullscreen with a timer.

2003 2012-10-05 Eli Zaretskii <eliz@gnu.org>
2005 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
2007 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
2008 that time stamps of directories could also be changed.
2009 Don't request the too broad GENERIC_WRITE, only the more restrictive
2010 FILE_WRITE_ATTRIBUTES access rights.
2012 * fileio.c (Fset_file_times): Special-case ignoring errors for
2013 directories only on MSDOS, not on MS-Windows.
2015 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
2017 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
2019 2012-10-04 Eli Zaretskii <eliz@gnu.org>

2026 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
2027 to avoid similar races.
2028 * keyboard.c (pending_signals): Now bool, not int.

2034 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
2035 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
2036 like OpenBSD, which has timer_settime but does not declare it.
2037 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
2038 whether to use itimerspec-related primitives. All uses of
2039 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
2041 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2043 * profiler.c (handle_profiler_signal): Fix a malloc race
2044 that caused Emacs to hang on Fedora 17 when profiling Lisp.

2048 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
2050 2012-10-02 Eli Zaretskii <eliz@gnu.org>
2052 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
2053 consistent with the change in return value of 'safe_strsignal'.
2055 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2057 Prefer plain 'static' to 'static inline' (Bug#12541).

2065 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
2066 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
2067 Now 'static', not 'static inline'.
2069 Count overruns when profiling; change units to ns.
2070 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
2071 Give extra weight to samples after overruns, to attempt to count
2072 the time more accurately.
2073 (setup_cpu_timer): Change sampling interval units from ms to ns, since
2074 the underlying primitives nominally do ns.
2075 (Fprofiler_cpu_start): Document the change. Mention that
2076 the sampling intervals are only approximate.
2078 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
2080 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.

2083 case for the special 0 coding-system.
2085 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
2086 (Fmake_overlay): Remove redundant tests.
2087 (fix_start_end_in_overlays): Remove redundant recentering.
2089 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
2091 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
2092 Update dependencies.
2094 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2096 Fix a malloc race condition involving strsignal.
2097 A signal can arrive in the middle of a malloc, and Emacs's signal
2098 handler can invoke strsignal, which can invoke malloc, which is
2099 not portable. This race condition bug makes Emacs hang on GNU/Linux.
2100 Fix it by altering the signal handler so that it does not invoke
2102 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
2103 * process.c (status_message): Use const pointer, in case strsignal
2104 is #defined to safe_strsignal.
2105 * sysdep.c (sys_siglist, init_signals): Always define and
2106 initialize a substitute sys_siglist if the system does not define
2107 one, even if HAVE_STRSIGNAL.
2108 (safe_strsignal): Rename from strsignal. Always define,
2109 using sys_siglist. Return a const pointer.
2110 * syssignal.h (safe_strsignal): New decl.
2111 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
2113 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2115 * w32proc.c (timer_loop): Fix code that waits for timer
2116 expiration, to avoid high CPU usage.
2118 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
2120 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
2121 (sweep_weak_table): Remove redundant prototypes.
2123 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
2125 * emacs.c: Move the inclusion of TERM_HEADER after including
2126 windows.h on WINDOWSNT. This avoids compilation problems with
2129 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2131 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
2132 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
2133 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
2134 as the previous version used 'void *'.
2136 * ralloc.c (ROUNDUP): Fix last change.
2137 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
2140 * w32proc.c <disable_itimers>: New static flag.
2141 (init_timers): Initialize it to zero, after creating the critical
2142 sections used by the timer threads.
2143 (term_timers): Set to 1 before deleting the critical sections.
2144 (getitimer, setitimer): If disable_itimers is non-zero, return an
2145 error indication without doing anything. Reported by Fabrice
2146 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
2147 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
2149 [!HAVE_SETITIMER]: Behave as the previous version that didn't
2152 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
2153 term_ntproc after all the other bookkeeping, to get timers working
2154 as long as possible.
2156 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2158 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
2159 Suggested by Juri Linkov in
2160 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
2162 Prefer plain 'static' to 'static inline' (Bug#12541).
2163 With static functions, modern compilers inline pretty well by
2164 themselves; advice from programmers often hurts as much as it helps.
2165 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
2166 this change shrinks the text size of the Emacs executable by 1.1%
2167 without affecting CPU significantly in my benchmark.
2168 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

2247 (bidi_copy_it): Do the whole copy with a single memcpy.
2248 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
2250 Revert the FOLLOW-SYMLINKS change for file-attributes.
2251 Doing it right would require several changes to Tramp, and there's
2252 not enough time to get that tested before the freeze today.
2253 * dired.c (directory_files_internal, Ffile_attributes):
2256 * frame.c (x_report_frame_params): Port better to wider ints.
2257 Do not assume that EMACS_UINT is the same width as uprintmax_t,
2258 or that pointers can be printed in 15 decimal digits.
2259 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

2440 Suggested by Eli Zaretskii in
2441 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
2443 2012-09-30 Eli Zaretskii <eliz@gnu.org>
2445 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
2446 HAVE_TIMER_SETTIME is defined.
2448 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
2450 Profiler improvements: more-accurate timers, overflow checks.
2451 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
2452 signal.h, setjmp.h. Include systime.h instead.
2453 (saturated_add): New function.

2460 All uses changed to store the new value.
2461 (handle_profiler_signal): Rename from sigprof_handler_1,
2462 for consistency with other handlers. Do not check whether
2463 cpu_log is a hash-table if garbage collecting, since it
2464 doesn't matter in that case.

2466 for consistency with other handlers.
2467 (setup_cpu_timer): New function, with much of what used to be in
2468 Fprofiler_cpu_start. Check for out-of-range argument.
2469 Prefer timer_settime if available, and prefer
2470 thread cputime clocks, then process cputime clocks, then
2471 monotonic clocks, to the old realtime clock. Use make_timeval
2472 to round more-correctly when falling back to setitimer.
2473 (Fprofiler_cpu_start): Use it.
2474 (Fprofiler_cpu_stop): Prefer timer_settime if available.
2475 Don't assume that passing NULL as the 2nd argument of setitimer

2478 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
2479 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
2480 non-fatal signal handlers. Ignore SIGPROF on startup.
2481 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
2482 in profiler.c, since sysdep.c now uses it.
2484 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

2540 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
2541 Since this stuff is now private to charset.c, there's no need for
2542 a public macro and no need to inline by hand.

2614 (sigaction): Rewrite to call sys_signal instead of duplicating its
2616 (sys_kill): Improve commentary.
2618 * w32.c (term_ntproc): Accept (and ignore) one argument, for
2619 consistency with a signature of a signal handler. All callers
2621 (init_ntproc): Accept an argument DUMPING. If dumping, don't
2622 install term_ntproc as a signal handler for SIGABRT, as that
2623 should be done by the dumped Emacs.
2625 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
2627 * w32select.c (term_w32select): Protect against repeated
2628 invocation by setting clipboard_owner to NULL after calling

2765 * emacs.c (terminate_due_to_signal): Reset signal handler here.
2766 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
2767 wanted even on POSIXish hosts, and it doesn't work on Windows.
2769 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
2771 * xterm.c (x_term_init): Call fixup_locale before and after calling
2772 gtk_init (Bug#12392).
2774 2012-09-23 Chong Yidong <cyd@gnu.org>
2776 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
2777 Vdynamic_library_alist.
2779 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
2780 (Fgnutls_available_p): Caller changed.
2782 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
2783 (Flibxml_parse_xml_region): Likewise.
2785 * dispextern.h (struct image_type): Remove arg from init function.
2787 * image.c (Finit_image_library, lookup_image_type)
2788 (define_image_type): Remove now-unneeded second arg.
2789 (init_xpm_functions, init_png_functions, init_jpeg_functions)
2790 (init_tiff_functions, init_gif_functions, init_svg_functions):
2791 Arglist and w32_delayed_load calling convention changed.
2792 (gs_type): Remove init_gs_functions; there is no such function.
2793 (valid_image_p, make_image): Fix caller to lookup_image_type.
2795 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
2797 Simplify and avoid signal-handling races (Bug#12471).
2799 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
2800 Avoid recursive loop if there's a fatal error in the function itself.
2801 * atimer.c (pending_atimers):
2802 * blockinput.h: Don't include "atimer.h"; no longer needed.
2803 (interrupt_input_pending): Remove. All uses removed.
2804 pending_signals now counts both atimers and ordinary interrupts.
2805 This is less racy than having three separate pending-signal flags.
2806 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
2808 Rename from their upper-case counterparts BLOCK_INPUT,
2809 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
2810 INPUT_BLOCKED_P, and turn into functions. All uses changed.
2811 This makes it easier to access volatile variables more accurately.
2812 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
2813 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
2814 that's more reliable if the code is buggy and sets
2815 interrupt_input_blocked to a negative value. All uses changed.
2816 * atimer.c (deliver_alarm_signal):
2817 Remove. No need to deliver this to the parent; any thread can
2818 handle this signal now. All uses replaced by underlying handler.
2819 * atimer.c (turn_on_atimers):
2820 * dispnew.c (handle_window_change_signal):
2821 * emacs.c (handle_danger_signal):
2822 * keyboard.c (kbd_buffer_get_event):
2823 Don't reestablish signal handler; not needed with sigaction.
2824 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
2826 Rework to avoid unnecessary accesses to volatile variables.
2827 (UNBLOCK_INPUT_TO): Now a function.
2828 (totally_unblock_input, unblock_input): New decls.
2829 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
2830 (init_data): Remove. Necessary stuff now done in init_signal.
2831 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
2832 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
2833 (fatal_error_code): Remove; no longer needed.
2834 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
2835 it doesn't always backtrace. All uses changed. No need to reset
2836 signal to default, since sigaction and/or die does that for us now.
2837 Use emacs_raise (FOO), not kill (getpid (), FOO).
2838 (main): Check more-accurately whether we're dumping.
2839 Move fatal-error setup to sysdep.c
2840 * floatfns.c: Do not include "syssignal.h"; no longer needed.
2841 * gtkutil.c (xg_get_file_name, xg_get_font):
2842 Remove no-longer-needed signal-mask manipulation.
2843 * keyboard.c, process.c (POLL_FOR_INPUT):
2844 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
2845 * keyboard.c (read_avail_input): Remove.
2846 All uses replaced by gobble_input.
2847 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
2848 (kbd_buffer_store_event_hold, gobble_input):
2849 (record_asynch_buffer_change) [USABLE_SIGIO]:
2850 (store_user_signal_events):
2851 No need to mess with signal mask.
2852 (gobble_input): If blocking input and there are terminals, simply
2853 set pending_signals to 1 and return. All hooks changed to not
2854 worry about whether input is blocked.
2855 (process_pending_signals): Clear pending_signals before processing
2856 them, in case a signal comes in while we're processing.
2857 By convention callers now test pending_signals before calling us.
2858 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
2859 New functions, to support changes to blockinput.h.
2860 (handle_input_available_signal): Now extern.
2861 (reinvoke_input_signal): Remove. All uses replaced by
2863 (quit_count): Now volatile, since a signal handler uses it.
2864 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
2865 All callers changed. Block SIGINT only if not already blocked.
2866 Clear sigmask reliably, even if Fsignal returns, which it can.
2867 Omit unnecessary accesses to volatile var.
2868 (quit_throw_to_read_char): No need to restore sigmask.
2869 * keyboard.c (gobble_input, handle_user_signal):
2870 * process.c (wait_reading_process_output):
2871 Call signal-handling code rather than killing ourselves.
2872 * lisp.h: Include <float.h>, for...
2873 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
2874 (pending_signals): Now volatile.
2875 (syms_of_data): Now const if IEEE floating point.
2876 (handle_input_available_signal) [USABLE_SIGIO]:
2877 (terminate_due_to_signal, record_child_status_change): New decls.
2878 * process.c (create_process): Avoid disaster if memory is exhausted
2879 while we're processing a vfork, by tightening the critical section
2881 (send_process_frame, process_sent_to, handle_pipe_signal)
2882 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
2884 (send_process): No need for setjmp/longjmp any more, since the
2885 SIGPIPE stuff is now gone. Instead, report an error if errno
2887 (record_child_status_change): Now extern. PID and W are now args.
2888 Return void, not bool. All callers changed.
2889 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
2890 Remove. All uses removed. This bug should be fixed now in a
2892 (wait_for_termination_1): Use waitpid rather than sigsuspend,
2893 and record the child status change directly. This avoids the
2894 need to futz with the signal mask.
2895 (process_fatal_action): Move here from emacs.c.
2896 (emacs_sigaction_flags): New function, containing
2897 much of what used to be in emacs_sigaction_init.
2898 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
2899 caught by emacs, to make races less likely.
2900 (deliver_process_signal): Rename from handle_on_main_thread.
2902 (BACKTRACE_LIMIT_MAX): Now at top level.
2903 (thread_backtrace_buffer, threadback_backtrace_pointers):
2905 (deliver_thread_signal, deliver_fatal_thread_signal):
2906 New functions, for more-accurate delivery of thread-specific signals.
2907 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
2908 (deliver_arith_signal): Handle in this thread, not
2909 in the main thread, since it's triggered by this thread.
2910 (maybe_fatal_sig): New function.
2911 (init_signals): New arg DUMPING so that we can be more accurate
2912 about whether we're dumping. Caller changed.
2913 Treat thread-specific signals differently from process-general signals.
2914 Block all signals while handling fatal error; that's safer.
2915 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
2917 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
2918 Ignore SIGPIPE unless batch.
2919 (emacs_backtrace): Output backtrace for the appropriate thread,
2920 which is not necessarily the main thread.
2921 * syssignal.h: Include <stdbool.h>.
2922 (emacs_raise): New macro.
2923 * xterm.c (x_connection_signal): Remove; no longer needed
2924 now that we use sigaction.
2925 (x_connection_closed): No need to mess with sigmask now.
2926 (x_initialize): No need to reset SIGPIPE handler here, since
2927 init_signals does this for us now.
2929 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
2931 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
2932 background rect may be larger (Bug#12245).
2934 2012-09-23 Chong Yidong <cyd@gnu.org>
2936 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
2938 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
2940 * .gdbinit: Just stop at fatal_error_backtrace.
2941 See Stefan Monnier's request in
2942 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
2943 Remove no-longer-used query of system type.
2945 2012-09-22 Chong Yidong <cyd@gnu.org>
2947 * search.c (Freplace_match): Doc fix (Bug#12325).
2949 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
2951 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
2952 (Fline_end_position): Doc fix.
2954 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
2956 2012-09-22 Chong Yidong <cyd@gnu.org>
2958 * dispextern.h (struct image_type): Add new slot, storing a type
2959 initialization function.
2961 * image.c (define_image_type): Call the image initializer function
2962 if it is defined. Arguments and return value changed.
2963 (valid_image_p, make_image): Callers changed.
2964 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
2965 (gif_type, imagemagick_type, svg_type, gs_type):
2966 Add initialization functions.
2967 (Finit_image_library): Call lookup_image_type.
2968 (CHECK_LIB_AVAILABLE): Macro deleted.
2969 (lookup_image_type): Call define_image_type here, rather than via
2970 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
2971 (syms_of_image): Move define_image_type calls for xbm_type and
2972 pbm_type to lookup_image_type.
2974 2012-09-22 Eli Zaretskii <eliz@gnu.org>
2976 * keyboard.c (timer_check_2): Move calculation of 'timers' and
2977 'idle_timers' from here ...
2978 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
2979 lists, to avoid infloops when the timer does something stupid,
2980 like reinvoke itself with the same or smaller time-out.
2983 2012-09-22 Martin Rudalics <rudalics@gmx.at>
2985 * window.c (Fsplit_window_internal): Handle only Qt value of
2986 Vwindow_combination_limit separately.
2987 (Qtemp_buffer_resize): New symbol.
2988 (Vwindow_combination_limit): New default value.
2991 2012-09-22 Eli Zaretskii <eliz@gnu.org>
2993 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
2994 the new overlay string. (Bug#10159)
2996 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
2998 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
2999 or that fprintf is async-signal-safe. POSIX doesn't require
3002 2012-09-22 Chong Yidong <cyd@gnu.org>
3004 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
3007 2012-09-22 Kenichi Handa <handa@gnu.org>
3009 * composite.c (composition_reseat_it): Handle the case that a
3010 grapheme cluster is not covered by a single font (Bug#12352).
3012 2012-09-21 Chong Yidong <cyd@gnu.org>
3014 * image.c (define_image_type): Avoid adding duplicate types to
3015 image_types (Bug#12463). Suggested by Jörg Walter.
3017 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3019 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
3020 (print_load_command_name): Add case LC_DATA_IN_CODE.
3021 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
3023 2012-09-21 Glenn Morris <rgm@gnu.org>
3025 * eval.c (Frun_hook_with_args_until_success)
3026 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
3028 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
3030 * fileio.c (Ffile_selinux_context): Only call freecon when
3031 lgetfilecon succeeded.
3032 (Fset_file_selinux_context): Likewise. (Bug#12444)
3034 2012-09-21 Eli Zaretskii <eliz@gnu.org>
3036 * xdisp.c (try_window_reusing_current_matrix): Under bidi
3037 reordering, locate the cursor by calling set_cursor_from_row; if
3038 that fails, clear the desired glyph matrix before returning a
3039 failure indication to the caller. Fixes leaving garbled display
3040 when fast scrolling with a down-key. (Bug#12403)
3041 (compute_stop_pos_backwards): Fix a typo that caused crashes while
3042 scrolling through multibyte text.
3044 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
3046 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
3047 calling mark_vectorlike since that's the one that marks the window.
3048 (mark_discard_killed_buffers): Mark the final cdr.
3049 * window.h (struct window): Move prev/next_buffers to the
3050 non-standard fields.
3051 * window.c (make_window): Initialize prev/next_buffers manually.
3053 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
3055 Omit unused arg EXPECTED from socket hooks.
3056 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
3057 * nsterm.m (ns_term_init):
3058 * termhooks.h (struct terminal.read_socket_hook):
3059 * w32inevt.c (w32_console_read_socket):
3060 * w32term.c (w32_read_socket):
3061 * xterm.c (XTread_socket):
3062 Omit unused arg EXPECTED. All callers changed.
3063 (store_user_signal_events): Return void, not int, since callers no
3064 longer care about the return value. All uses changed.
3066 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
3068 * w32gui.h (XParseGeometry): Do not declare.
3070 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
3072 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
3073 Ignore 'expected'. See Eli Zaretskii in
3074 <http://bugs.gnu.org/12471#8> (last line).
3076 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
3077 (XParseGeometry): Now static. Substitute extremal values for
3078 values that are out of range.
3080 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
3082 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
3084 * nsfns.m (XParseGeometry): Remove.
3085 (Fx_create_frame): Call x_set_offset to correctly interpret
3086 top_pos in geometry.
3088 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
3089 (Fx_parse_geometry): If there is a space in string, call
3090 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
3092 2012-09-17 Eli Zaretskii <eliz@gnu.org>
3094 * search.c (scan_buffer): Use character positions in calls to
3095 region_cache_forward and region_cache_backward, not byte
3096 positions. (Bug#12196)
3098 * w32term.c (w32_read_socket): Set pending_signals to 1, like
3099 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
3101 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
3102 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
3103 emacs_blocked_malloc, now deleted.
3105 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
3107 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
3108 The workaround was for improving performance on Solaris 2.4, but
3109 is getting in the way now. Emacs will still work if someone is
3110 still running Solaris 2.4 in a museum somewhere; Sun dropped
3111 support for Solaris 2.4 in 2003.
3112 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
3113 * process.c (create_process) [HAVE_WORKING_VFORK]:
3114 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
3115 since Emacs no longer uses vfork on that platform.
3117 2012-09-17 Glenn Morris <rgm@gnu.org>
3119 * emacs.c: Use COPYRIGHT.
3121 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
3123 Remove configure's --without-sync-input option (Bug#12450).
3124 When auditing signal-handling in preparation for cleaning it up,
3125 I found that SYNC_INPUT has race conditions and would be a real
3126 pain to fix. Since it's an undocumented and deprecated
3127 configure-time option, now seems like a good time to remove it.
3128 Also see <http://bugs.gnu.org/11080#16>.
3129 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
3130 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
3131 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3132 (malloc_hysteresis):
3133 (check_depth) [XMALLOC_OVERRUN_CHECK]:
3134 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
3135 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
3136 (dont_register_blocks, bytes_used_when_reconsidered)
3137 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
3138 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
3139 [!SYSTEM_MALLOC && !SYNC_INPUT]:
3140 Remove. All uses removed.
3141 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
3142 implementation, one that depends on whether the new macro
3143 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
3145 * atimer.c (run_timers, handle_alarm_signal):
3146 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
3147 (handle_async_input, process_pending_signals)
3148 (handle_input_available_signal, init_keyboard):
3149 * nsterm.m (ns_read_socket):
3150 * process.c (wait_reading_process_output):
3151 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
3152 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
3154 * xterm.c (XTread_socket):
3156 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
3157 * eval.c (handling_signal): Remove. All uses removed.
3158 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
3159 All uses replaced with the SYNC_INPUT version.
3160 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
3162 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3165 * font.c (Ffont_shape_gstring): Remove unused local.
3167 2012-09-16 Glenn Morris <rgm@gnu.org>
3169 * Makefile.in (clean): No longer run nextstep's clean.
3171 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
3173 (ns-app): Move here from ns.mk, and simplify.
3174 (clean): Simplify nextstep entry.
3175 * ns.mk: Remove file.
3177 2012-09-17 Kenichi Handa <handa@gnu.org>
3179 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
3180 not covert the last few charactes.
3182 2012-09-16 Kenichi Handa <handa@gnu.org>
3184 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
3185 here, but just check the validity of glyphs in the glyph-string.
3187 2012-09-16 Martin Rudalics <rudalics@gmx.at>
3189 * window.c (Fwindow_parameter, Fset_window_parameter):
3190 Accept any window as argument (Bug#12452).
3192 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
3194 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
3195 to ns_term_init to avoid memory leak.
3197 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
3198 explicit retain/release.
3199 (ns_term_init): Only allow one display. Initialize outerpool and
3202 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3204 Port _setjmp fix to POSIXish hosts as well as Microsoft.
3205 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
3206 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
3207 the Microsoft problem in a different way, by altering ../nt/config.nt.
3209 2012-09-15 Eli Zaretskii <eliz@gnu.org>
3224 * w16select.c: Remove inclusion of setjmp.h, as it is now included
3225 by lisp.h. This completes removal of setjmp.h inclusion
3226 erroneously announced in the previous commit. (Bug#12446)
3228 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
3231 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
3232 not defined as a macro. The latter happens on MS-Windows.
3235 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3237 Port better to POSIX hosts lacking _setjmp (Bug#12446).
3238 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
3239 Some instances of '#include <setjmp.h>' removed, if the
3240 only reason for the instance was because "lisp.h" was included.
3241 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
3242 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
3243 and _longjmp with the new symbols. Emacs already uses _setjmp if
3244 available, so this change affects only POSIXish hosts that have
3245 sigsetjmp but not _setjmp, such as some versions of Solaris and
3246 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
3247 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
3248 (png_load_body) [HAVE_PNG]:
3249 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
3250 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
3251 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
3252 since PNG requires jmp_buf. This is the only exception to the
3253 general rule that we now use sys_setjmp and sys_longjmp.
3254 This exception is OK since this code does not change the signal
3255 mask or longjmp out of a signal handler.
3257 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
3259 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3260 Include "syssignal.h", for 'main_thread'.
3262 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
3264 Avoid out-of-range marker position (Bug#12426).
3265 * insdel.c (replace_range, replace_range_2):
3266 Adjust markers before overlays, as suggested by comments.
3267 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
3268 Remove redundant check before calling offset_intervals.
3270 2012-09-14 Martin Rudalics <rudalics@gmx.at>
3272 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
3273 current buffer (Bug#12387).
3275 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
3277 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
3279 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3281 Use a more backwards-compatible timer format (Bug#12430).
3282 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
3283 vector element, not from the 4th, since PSECS is now at the end.
3284 (Fcurrent_idle_time): Doc fix.
3286 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
3288 Function to mark objects and remove killed buffers at once.
3289 * alloc.c (discard_killed_buffers): Rename to ...
3290 (mark_discard_killed buffers) ... new name. Add marking
3291 of remaining objects. Fix comment. Adjust users.
3292 (mark_object): Do not touch frame buffer lists here.
3293 * frame.c (delete_frame): Reset frame buffer lists here.
3295 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3297 Better workaround for GNOME bug when --enable-gcc-warnings.
3298 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
3299 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
3300 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
3302 Simplify SIGIO usage (Bug#12408).
3303 The code that dealt with SIGIO was crufty and confusing, e.g., it
3304 played tricks like "#undef SIGIO" but these tricks were not used
3305 consistently. Simplify mostly by not #undeffing standard symbols,
3306 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
3307 or not as we please) rather than "defined SIGIO" (standard symbol
3308 that we probably shouldn't #undef).
3309 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
3310 Modules that need it can include it.
3311 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
3312 * dispextern.h (ignore_sigio): New decl.
3313 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
3314 unconditionally, since it's now a no-op if !USABLE_SIGIO.
3315 * emacs.c (shut_down_emacs):
3316 * keyboard.c (kbd_buffer_store_event_hold):
3317 Use ignore_sigio rather than invoking 'signal' directly.
3318 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
3320 (FIONREAD, SIGIO): Do not #undef.
3321 (tty_read_avail_input): Use #error rather than a syntax error.
3322 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
3323 for I_PIPE, used by SETUP_SLAVE_PTY.
3324 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
3325 * sysdep.c (croak): Remove; no longer needed. This bit of
3326 temporary code, with Fred N. Fish's comment that it's temporary,
3327 has been in Emacs since at least 1992!
3328 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
3329 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
3330 * syssignal.h (croak): Remove decl.
3331 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
3332 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
3333 now that we're termios-only.
3334 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
3335 * term.c (dissociate_if_controlling_tty): Use #error rather than
3338 Work around GCC and GNOME bugs when --enable-gcc-warnings.
3339 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
3340 to work around GNOME bug 683906.
3341 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
3342 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
3343 This works around GCC bug 54561.
3345 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
3347 More fixes for 'volatile' and setjmp/longjmp.
3348 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
3349 * image.c (struct png_load_context) [HAVE_PNG]: New type.
3350 (png_load_body) [HAVE_PNG]:
3351 (jpeg_load_body) [HAVE_JPEG]:
3352 New function, with most of the old parent function's body.
3353 (png_load) [HAVE_PNG]:
3354 (jpeg_load) [HAVE_JPEG]:
3355 Invoke the new function, to avoid longjmp munging our locals.
3356 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
3357 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
3358 longjmp is passed 2, as the C standard doesn't guarantee this.
3359 Instead, store the failure code into mgr->failure_code.
3361 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
3363 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
3364 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
3365 (syms_of_keyboard): Remove support for unread-command-char.
3367 2012-09-12 Eli Zaretskii <eliz@gnu.org>
3369 * w32proc.c (sys_kill): If PID is our process ID and the signal is
3370 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
3371 violation. (Bug#12426)
3373 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
3375 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
3377 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
3379 * eval.c: Add `inhibit-debugger'.
3380 (Qinhibit_debugger): New symbol.
3381 (call_debugger): Bind it instead of Qdebug_on_error.
3382 (maybe_call_debugger): Test Vinhibit_debugger.
3383 (syms_of_eval): Define inhibit-debugger.
3384 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
3385 (syms_of_xdisp): Remove inhibit-debug-on-message.
3387 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
3389 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
3390 If a nonvolatile local variable is written before a _longjmp to
3391 the frame containing the variable, and is read after the _longjmp,
3392 the value read is indeterminate. Some local variables of type
3393 'struct handler' and 'struct catchtag' are used in this way, so
3394 mark each of their slots as volatile if the slot can be set before
3395 _longjmp and read afterwards.
3396 * lisp.h (struct handler): var and chosen_clause are now volatile.
3397 (struct catchtag): val, next, and pdlcount are now volatile.
3399 * bidi.c (bidi_push_it, bidi_pop_it):
3400 * fns.c (copy_hash_table):
3401 * image.c (define_image_type):
3402 * keyboard.c (kbd_buffer_store_event_hold):
3403 * process.c (Fprocess_send_eof):
3404 * xfaces.c (x_create_gc) [HAVE_NS]:
3405 * xgselect.c (xg_select):
3406 Prefer assignment to memcpy when either will do.
3408 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
3409 Use pointer-to-a-pointer to simplify and avoid a NILP check each
3410 time an item is removed. No need to mark this function 'inline';
3411 the compiler knows better than we do.
3413 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
3415 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
3416 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
3417 to change_frame_size (Bug#12388).
3418 (windowDidResize:): Pass YES to updateFrameSize.
3420 * nsterm.h: Add delay parameter to updateFrameSize.
3422 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
3424 Discard killed buffers from deleted window and frame objects.
3425 This reduces an amount of references to killed buffers and
3426 helps GC to reclaim them faster.
3427 * alloc.c (discard_killed_buffers): New function.
3428 (mark_object): Use it for deleted windows and frames.
3429 (mark_object): If symbol's value is set up for a killed buffer
3430 or deleted frame, restore its global binding.
3431 * data.c (swap_in_global_binding): Add GC notice.
3432 (swap_in_symval_forwarding): Use convenient set_blv_where.
3433 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
3434 * window.h: ... to here.
3436 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
3438 Convenient macro to check whether the buffer is live.
3439 * buffer.h (BUFFER_LIVE_P): New macro.
3440 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
3441 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
3443 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3445 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
3446 composition cases (Bug#12364).
3448 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
3449 overhang of succeeding glyphs overlapping box cursor.
3451 * w32term.c (x_draw_glyph_string): Likewise.
3453 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
3455 Simplify, document, and port floating-point (Bug#12381).
3456 The porting part of this patch fixes bugs on non-IEEE platforms
3457 with frexp, ldexp, logb.
3458 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
3460 * floatfns.c: Simplify discussion of functions that Emacs doesn't
3461 support, by removing commented-out code and briefly listing the
3462 C89 functions excluded. The commented-out stuff was confusing
3463 maintenance, e.g., we thought we needed cbrt but it was commented out.
3464 (logb): Remove decl; no longer needed.
3465 (isfinite): New macro, if not already supplied.
3466 (isnan): Don't replace any existing macro.
3467 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
3468 are present on all C89 platforms.
3469 (Ffrexp): Do not special-case zero, as frexp does the right thing
3471 (Flogb): Do not use logb, as it doesn't have the desired meaning
3472 on hosts that use non-base-2 floating point. Instead, stick with
3473 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
3474 frexp, to avoid getting an unspecified result.
3476 * xdisp.c (Qinhibit_debug_on_message): Now static.
3478 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
3480 * nsterm.m (ns_update_begin): Set clip path to whole view by using
3481 NSBezierPath (Bug#12131).
3483 2012-09-10 Chong Yidong <cyd@gnu.org>
3485 * fns.c (Fdelq, Fdelete): Doc fix.
3487 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
3489 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
3490 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
3492 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
3494 * lisp.h (make_lisp_ptr): New macro to replace XSET.
3495 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
3498 2012-09-09 Eli Zaretskii <eliz@gnu.org>
3500 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
3501 left fringe if the window has a left margin. This avoids leaving
3502 traces of the cursor because its leftmost pixel is not drawn over.
3504 * dispnew.c (update_window_line): When the left margin area of a
3505 screen line is updated, set the redraw_fringe_bitmaps_p flag of
3506 that screen line. (Bug#12277)
3508 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
3510 Assume C89 or later for math functions (Bug#12381).
3511 This simplifies the code, and makes it a bit smaller and faster,
3512 and (most important) makes it easier to clean up signal handling
3513 since we can stop worring about floating-point exceptions in
3514 library code. That was a problem before C89, but the problem
3515 went away many years ago on all practical Emacs targets.
3516 * data.c, image.c, lread.c, print.c:
3517 Don't include <math.h>; no longer needed.
3518 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
3519 might be autoconfigured, as that never happens.
3521 * doprnt.c (DBL_MAX_10_EXP):
3522 * print.c (DBL_DIG):
3523 Remove. C89 or later always defines these.
3524 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
3525 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
3526 (arith_error, domain_error, domain_error2):
3527 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
3528 no longer needed -- we simply return what C returns. All uses removed.
3529 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
3531 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
3532 Remove. All uses expanded, as these macros are no longer used
3533 more than once and are now more trouble than they're worth.
3534 (Ftan): Use tan, not sin / cos.
3535 (Flogb): Assume C89 frexp.
3536 (fmod_float): Assume C89 fmod.
3537 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
3538 (init_floatfns): Remove. All uses removed.
3540 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3542 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
3543 compositeToPoint for OSX < 10.6 (Bug#12390).
3545 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
3547 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
3548 This produces more-accurate results.
3550 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3552 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
3553 changes (Bug#12088).
3555 2012-09-08 Chong Yidong <cyd@gnu.org>
3557 * syntax.c (Fstring_to_syntax): Doc fix.
3559 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3561 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
3562 in the internal border.
3563 (x_set_window_size): Remove static variables and their usage.
3564 (ns_redraw_scroll_bars): Fix NSTRACE arg.
3565 (ns_after_update_window_line, ns_draw_fringe_bitmap):
3566 Remove fringe/internal border adjustment (Bug#11052).
3567 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
3568 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
3569 (ns_fix_rect_ibw): Remove.
3570 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
3571 (ns_dumpglyphs_box_or_relief): Ditto.
3572 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
3574 (ns_dumpglyphs_image): Ditto.
3575 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
3577 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
3578 their usage. Add fringe_extended_p and its use as in other terms.
3579 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
3580 scroll bar was removed.
3581 (updateFrameSize): New function.
3582 (windowDidResize): Move code to updateFrameSize and call it.
3584 * nsterm.h (EmacsView): Add updateFrameSize.
3586 2012-09-07 Chong Yidong <cyd@gnu.org>
3588 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
3590 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
3592 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
3594 More signal-handler cleanup (Bug#12327).
3595 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
3596 Problem introduced when merging patches. Noted by Eli Zaretskii in
3597 <http://bugs.gnu.org/12327#67>.
3598 * floatfns.c: Comment fix.
3599 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
3600 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
3601 and anyway the declaration is harmless even if SIGDANGER is not defined.
3602 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
3603 defined BROKEN_FIONREAD). systty.h formerly did this, but other
3604 source files not surprisingly expected syssignal.h to define, or
3605 not define, SIGIO, and it's cleaner to do it that way, for consistency.
3606 Include <sys/ioctl.h>, for FIONREAD.
3607 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
3608 This eliminates a problem whereby other files mysteriously had
3609 to include "syssignal.h" before including "systty.h" if they
3610 wanted to use "#ifdef SIGIO".
3612 2012-09-07 Eli Zaretskii <eliz@gnu.org>
3614 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
3616 * w32.c (sigemptyset): Empty the set.
3617 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
3619 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
3621 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
3623 * alloc.c (mark_buffer): Revert unsafe marking optimization.
3624 (mark_object): Likewise for frame objects.
3626 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
3628 * syssignal.h (handle_on_main_thread): Always declare,
3629 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
3630 This ports to platforms without HAVE_PTHREAD.
3632 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
3634 Signal-handler cleanup (Bug#12327).
3635 Emacs's signal handlers were written in the old 4.2BSD style with
3636 sigblock and sigmask and so forth, and this led to some
3637 inefficiencies and confusion. Rewrite these to use
3638 pthread_sigmask etc. without copying signal sets around. Also,
3639 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
3640 'signal', and instead use functions that do not attempt to take
3641 over the system name space. This patch causes Emacs's text
3642 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
3643 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
3644 Do not include <signal.h> or "syssignal.h", as these
3645 modules do not use signals.
3646 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
3647 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
3648 Do not include <signal.h>, as "syssignal.h" does that for us now.
3649 * atimer.c (sigmask_atimers): New function.
3650 (block_atimers, unblock_atimers): New functions,
3651 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
3653 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
3654 no longer needed here.
3655 * emacs.c (main): Inspect existing signal handler with sigaction,
3656 so that there's no need to block and unblock SIGHUP.
3657 * sysdep.c (struct save_signal): New member 'action', replacing
3658 old member 'handler'.
3659 (save_signal_handlers, restore_signal_handlers):
3660 Use sigaction instead of 'signal' to save and restore.
3661 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
3662 New function. All users of 'signal' modified to use set_sighandler
3663 if they're writeonly, and to use sys_signal if they're read+write.
3664 (emacs_sigaction_init, forwarded_signal): New functions.
3665 (sys_signal): Remove. All uses replaced by calls to sigaction
3666 and emacs_sigaction_init, or by direct calls to 'signal'.
3667 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
3668 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
3669 all uses replaced by pthread_sigmask etc. calls.
3670 * syssignal.h: Include <signal.h>.
3671 (emacs_sigaction_init, forwarded_signal): New decls.
3672 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
3673 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
3674 (sigmask, sys_sigmask): Remove; no longer needed.
3675 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
3676 (sigblock, sigunblock, sigfree):
3677 (sigsetmask) [!defined sigsetmask]:
3678 Remove. All uses replaced by pthread_sigmask.
3679 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
3680 no longer need to be replaced, and its typical old uses
3681 are now done via emacs_sigaction_init and sigaction.
3682 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
3683 (sys_sigdel): Remove; unused.
3684 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
3686 2012-09-06 Eli Zaretskii <eliz@gnu.org>
3688 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
3689 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
3691 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
3693 Explicitly mark buffer_defaults and buffer_local_symbols.
3694 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
3695 mark_local_symbols here.
3696 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
3697 since special buffers aren't marked here any more.
3698 (allocate_buffer): Chain new buffer with all_buffers here...
3699 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
3701 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
3702 (syms_of_buffer): Remove staticpro of the above.

3706 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
3708 Use bool for booleans in font-related modules.
3709 * font.c (font_intern_prop, font_style_to_value)
3710 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
3711 (generate_otf_features, font_check_otf_features, font_check_otf)
3712 (font_match_p, font_list_entities, font_at):
3713 * fontset.c (fontset_id_valid_p, reorder_font_vector
3714 (fontset_find_font, Fset_fontset_font)
3715 (face_suitable_for_char_p) [0]:
3716 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
3717 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
3718 (m17n_flt_initialized, ftfont_shape_by_flt):
3719 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
3720 * nsfont.m (nsfont_draw):
3721 * w32font.c (w32font_draw):
3722 * w32term.c (x_draw_glyphless_glyph_string_foreground):
3723 Use bool for booleans.
3724 * font.h: Adjust to above API changes.
3725 (struct font, struct font_driver, struct font_driver_list):
3726 Use bool for booleans.
3727 (struct font): Remove useless member encoding_type.
3729 * fontset.c, xftfont.c: Omit unnecessary static decls.
3731 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
3733 * alloc.c (mark_object): Revert window marking code
3734 since it's unsafe for the Fset_window_configuration.
3736 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
3738 Fix race conditions with signal handlers and errno (Bug#12327).
3739 Be more systematic about preserving errno whenever a signal
3740 handler returns, even if it's not in the main thread. Do this by
3741 renaming signal handlers to distinguish between signal delivery
3742 and signal handling. All uses changed.
3743 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
3744 * data.c (deliver_arith_signal): Rename from arith_error.
3745 * dispnew.c (deliver_window_change_signal): Rename from
3746 window_change_signal.
3747 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
3748 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
3749 * keyboard.c (deliver_input_available_signal): Rename from
3750 input_available_signal.
3751 (deliver_user_signal): Rename from handle_user_signal.
3752 (deliver_interrupt_signal): Rename from interrupt_signal.
3753 * process.c (deliver_pipe_signal): Rename from send_process_trap.
3754 (deliver_child_signal): Rename from sigchld_handler.
3755 * atimer.c (handle_alarm_signal):
3756 * data.c (handle_arith_signal):
3757 * dispnew.c (handle_window_change_signal):
3758 * emacs.c (handle_fatal_signal, handle_danger_signal):
3759 * keyboard.c (handle_input_available_signal):
3760 * keyboard.c (handle_user_signal, handle_interrupt_signal):
3761 * process.c (handle_pipe_signal, handle_child_signal):
3762 New functions, with the actual signal-handling code taken from the
3763 original respective signal handlers, sans the sporadic attempts to
3764 preserve errno, since that's now done by handle_on_main_thread.
3765 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
3766 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
3767 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3769 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3770 Move initialization of main_thread to sysdep.c's init_signals.
3771 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
3772 our usage, and simplifies the mainline code.
3773 (record_child_status_change): New static function, as a helper
3774 for handle_child_signal, and with most of the old child handler's
3776 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
3777 (handle_child_signal): Use the above.
3778 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3779 Moved here from emacs.c.
3780 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
3781 code moved here from emacs.c's main function.
3782 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
3783 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
3784 This lets callers save and restore errno properly.
3786 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3788 Remove redundant or unused things here and there.
3789 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
3790 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
3791 * editfns.c (Fcompare_buffer_substrings): Likewise.
3792 * frame.h (struct terminal, struct font_driver_list):
3793 Remove redundant declarations.
3794 * window.h (Qleft, Qright): Likewise.
3796 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3798 Do not mark objects from deleted buffers, windows and frames.
3799 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
3800 (mark_object): Likewise for windows and frames.
3802 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3804 * alloc.c (valid_lisp_object_p): Treat killed buffers,
3805 buffer_defaults and buffer_local_symbols as valid objects.
3806 Return special value to denote them.
3808 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
3810 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
3811 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
3812 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
3813 (file_name_absolute_p, Fsubstitute_in_file_name):
3814 (check_executable, check_writable, Ffile_accessible_directory_p)
3815 (Fset_file_selinux_context, Fdefault_file_modes)
3816 (Finsert_file_contents, choose_write_coding_system)
3817 (Fwrite_region, build_annotations, a_write, e_write)
3819 * filelock.c (boot_time_initialized, get_boot_time)
3820 (get_boot_time_1, lock_file_1, within_one_second):
3821 * floatfns.c (in_float):
3822 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
3823 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
3824 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
3825 * lisp.h (struct Lisp_Hash_Table.cmpfn):
3826 * window.c (compare_window_configurations):
3827 Use bool for booleans.
3828 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
3829 (Fdefault_file_modes): Now mode_t, not int, for modes.
3830 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
3831 (internal_delete_file): Now returns void, not a (boolean) int,
3832 since nobody was looking at the return value.
3833 * lisp.h, window.h: Adjust to above API changes.
3835 * xdisp.c (set_message): Simplify and reindent last change.
3837 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
3839 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
3841 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
3843 * eval.c (call_debugger): Make the function non-static so that we
3844 can call it from set_message.
3846 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
3847 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
3849 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3851 Give more-useful info on a fatal error (Bug#12328).
3852 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
3853 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
3854 of doing the work ourselves.
3855 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
3856 do most of the work.
3857 (fatal_error_backtrace): New function, taken from the guts
3858 of the old fatal_error_signal, but with a new option to output
3860 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
3861 info about the signal than just its number.
3862 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
3863 * sysdep.c: Include <execinfo.h>
3864 (emacs_backtrace): New function, taken partly from the previous
3865 code of the 'die' function.
3866 (emacs_abort): Call fatal_error_backtrace rather than abort.
3868 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
3870 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
3871 eager (load-time) macro-expansion.
3872 * lisp.mk (lisp): Add macroexp.
3874 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3876 Simplify redefinition of 'abort' (Bug#12316).
3877 Do not try to redefine the 'abort' function. Instead, redo
3878 the code so that it calls 'emacs_abort' rather than 'abort'.
3879 This removes the need for the NO_ABORT configure-time macro
3880 and makes it easier to change the abort code to do a backtrace.
3881 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
3882 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
3883 Remove; sysdep.c's emacs_abort now takes its place.
3884 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
3885 'abort' changed to use 'emacs_abort'.
3886 * msdos.c (dos_abort) [defined abort]: Remove; not used.
3887 (abort) [!defined abort]: Rename to ...
3888 (emacs_abort): ... new name.
3889 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
3890 the place of the old 'abort' in emacs.c.
3891 * w32.c, w32fns.c (abort): Do not #undef.
3892 * w32.c (emacs_abort): Rename from w32_abort.
3894 2012-09-04 Eli Zaretskii <eliz@gnu.org>
3896 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
3897 offsets[j].dv, since the y axis of the screen coordinates points
3898 down, while the y axis of the font definition coordinates points
3899 up. This fixes display of Arabic diacritics such as KASRA and
3900 KASRATAN. (Bug#11860)
3902 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3904 Be more systematic about _setjmp vs setjmp.
3905 * alloc.c (test_setjmp, mark_stack):
3906 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
3907 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
3908 (png_load, my_error_exit, jpeg_load):
3909 * process.c (send_process_trap, send_process):
3910 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
3911 The underscored versions are up to 30x faster on some hosts.
3912 Formerly, the code used setjmp+longjmp sometimes and
3913 _setjmp+_longjmp at other times, with no particular reason to
3914 prefer setjmp+longjmp.
3916 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
3918 Fix minor problem found by static checking.
3919 * buffer.c (Fdelete_all_overlays): Return nil.
3921 2012-09-03 Martin Rudalics <rudalics@gmx.at>
3923 * buffer.c (Fdelete_all_overlays): New function.
3925 2012-09-03 Chong Yidong <cyd@gnu.org>
3927 * gtkutil.c: Add extern decl for Qxft.
3929 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
3931 * emacs.c, eval.c: Use bool for boolean.
3932 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
3933 (malloc_using_checking) [DOUG_LEA_MALLOC]:
3934 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
3935 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
3936 (main, decode_env_path, Fdaemon_initialized):
3937 * eval.c (call_debugger, Finteractive_p, interactive_p):
3938 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
3939 (maybe_call_debugger, Fbacktrace):
3940 * process.c (read_process_output, exec_sentinel):
3941 Use bool for booleans.
3942 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
3943 All callers changed.
3944 * eval.c (interactive_p): Omit always-true boolean argument
3945 EXCLUDE_SUBRS_P. All callers changed.
3946 * dispextern.h, lisp.h: Reflect above API changes.
3947 * firstfile.c (dummy): Use the address of 'main', whose signature
3948 won't change, instead of the address of 'initialize', whose
3949 signature just changed from int to bool.
3950 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
3951 * msdos.c (fatal_error_in_progress): ... from here.
3952 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
3954 (redisplay_internal, unwind_redisplay): Simply clear
3955 REDISPLAYING_P when unwinding, instead of saving its previous,
3956 always-false value and then restoring it.
3958 Clean up some extern decls.
3959 Mostly, this hoists extern decls out of .c files and into .h files.
3960 That way, we're more likely to catch errors if the interfaces change.
3961 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
3962 declare xg_mark_data.
3963 * dispextern.h (x_frame_parm_handlers):
3965 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
3966 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
3967 (Qultra_bold, Qoblique, Qitalic):
3968 Move extern decl here from .c file.
3969 * alloc.c (xg_mark_data) [USE_GTK]:
3971 * eval.c (Qlexical_binding):
3972 * fns.c (time) [!HAVE_UNISTD_H]:

3978 * process.c (QCfamily, QCfilter):
3979 * widget.c (free_frame_faces):
3980 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
3981 * xfont.c (x_clear_errors):
3982 * xterm.c (x_frame_parm_handlers):
3983 Remove now-redundant extern decls.
3984 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
3985 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
3987 * xfaces.c: Remove unnecessary static decls.
3988 * xterm.c (updating_frame): Remove decl of nonexistent object.
3990 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
3991 when building globals.h, as the objects that are not built on
3992 this host are not needed to compile C files on this host.
3994 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
3996 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
3998 * frame.h: Add missing prototype for x_wm_set_size_hint.
4000 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

4004 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
4005 (Fsubstitute_command_keys):

4007 (save_excursion_save, save_excursion_restore)
4008 (disassemble_lisp_time, decode_time_components, emacs_nmemftime)

4010 (make_buffer_string, make_buffer_string_both)
4011 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):

4025 Use bool for boolean.
4026 * intervals.h, lisp.h, systime.h: Reflect above API changes.
4027 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
4029 2012-09-02 Chong Yidong <cyd@gnu.org>
4031 * keymap.c (push_key_description): Print M-TAB as C-M-i
4034 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
4036 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
4037 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))
4038 ($(BLD)/editfns.$(O), $(BLD)/ccl.$(O), $(BLD)/chartab.$(O))

4042 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
4044 2012-09-01 Eli Zaretskii <eliz@gnu.org>
4046 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
4047 more than one grapheme cluster passed to the shaper: compute the
4048 offset adjustment values separately for each cluster. (Bug#11860)
4050 * image.c: Restore mistakenly removed inclusion of w32.h. Without
4051 it, GCC doesn't see prototypes of w32_delayed_load, and complains
4052 about implicit conversions from integer to pointer.
4054 2012-09-01 Daniel Colascione <dancol@dancol.org>
4056 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
4057 system used too early.
4059 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
4061 Better seed support for (random).
4062 * emacs.c (main): Call init_random.
4063 * fns.c (Frandom): Set the seed from a string argument, if given.
4064 Remove long-obsolete Gentzel cruft.
4065 * lisp.h, sysdep.c (seed_random): Now takes address and size, not long.
4066 (init_random): New function.
4068 2012-09-01 Daniel Colascione <dancol@dancol.org>
4070 * xterm.h: Add header guards. Declare x_menubar_window_to_frame.
4071 Remove x_set_frame_alpha, x_bitmap_icon, x_make_frame_visible,
4072 x_make_frame_invisible, x_iconify_frame, x_free_frame_resources,
4073 x_wm_set_size_hint, x_query_colors, x_real_positions,
4074 x_set_menu_bar_lines, x_char_width, x_char_height, x_sync,
4075 x_set_tool_bar_lines, x_activate_menubar, and free_frame_menubar,

4166 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
4167 does not become zero (Bug#12234).

4197 (timeout_handler:): Set timer_fired to YES.
4198 (runDialogAt:): Set timer_fired to NO.
4199 Handle click on close button as quit.
4201 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
4202 Add window_closed and button_values. Add void as return value for
4203 add(Button|String|Split). addButton takes int instead of Lisp_Object.
4204 Add process_dialog as new member.
4206 2012-08-28 Eli Zaretskii <eliz@gnu.org>
4208 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it

4281 2012-08-27 Martin Rudalics <rudalics@gmx.at>
4283 * window.c (Fset_window_configuration): Revert first part of
4286 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
4288 * nsterm.h (NSPanel): New class variable dialog_return.

4291 Initialize dialog_return.
4292 (windowShouldClose:): Use stop instead of stopModalWithCode.
4293 (clicked:): Ditto, and also set dialog_return (Bug#12258).
4294 (timeout_handler:): Use stop instead of abortModal. Send a dummy

4344 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
4345 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
4346 not a boolean 'int', since callers never look at the return value.

4349 (emacs_mule_string_char): Remove unused extern decls.
4350 (struct iso_2022_spec, struct coding_system):

4358 Fix spare memory change (Bug#12286).
4359 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
4360 (valid_lisp_object_p): Likewise.
4362 2012-08-27 Martin Rudalics <rudalics@gmx.at>
4364 * window.c (Fset_window_configuration): Record any window's old
4365 buffer if it's replaced (see Bug#8789). If the new current
4366 buffer doesn't appear in the selected window, go to its old
4369 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
4371 Special MEM_TYPE_SPARE to denote reserved memory.
4372 * alloc.c (enum mem_type): New memory type.
4373 (refill_memory_reserve): Use new type for spare memory.
4374 This prevents live_cons_p and live_string_p from incorrect

4377 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
4380 * Makefile.in (.PHONY): versioclean -> versionclean.

4384 * window.c (Qwindow_valid_p, decode_valid_window):
4385 Now static, not extern.
4386 * data.c (Qinterval): Remove; unused.

4403 (map_sub_char_table):
4404 Use bool for boolean.
4405 * character.c (str_to_unibyte): Omit last boolean argument; it was
4406 always 0. All callers changed.
4407 * character.h, charset.h: Adjust to match previous changes.
4408 * character.h (char_printable_p): Remove decl of nonexistent function.
4409 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
4410 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
4411 are all boolean, so make them single-bit bitfields.
4413 * lisp.h (ASET): Remove attempt to detect side effects.
4414 It was meant to be temporary and it often doesn't work,
4415 because when IDX has side effects the behavior of IDX==IDX
4416 is undefined. See Stefan Monnier in
4417 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
4419 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
4421 * lisp.h (functionp): New function (extracted from Ffunctionp).
4422 (FUNCTIONP): Use it.
4423 * eval.c (Ffunctionp): Use it.
4425 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
4427 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
4428 as that's faster and simpler than static storage. Don't bother
4429 with the g_main_context_query overhead if g_main_context_pending
4430 says no events are pending.
4431 (gfds, gfds_size): Remove these static vars.
4432 (xgselect_initialize): Remove; no longer needed.
4433 All uses and decls removed.
4435 * emacs.c (fatal_error_signal_hook): Remove.
4436 All uses removed. This leftover from old code was always 0.
4438 * casefiddle.c, casetab.c, category.c: Use bool for boolean.

4463 Use bool for booleans, instead of int.
4464 * lisp.h, process.h: Adjust prototypes to match above changes.
4465 * callint.c (Fcall_interactively): Don't assume the mark's
4466 offset fits in 'int'.

4478 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
4479 Use bool for booleans, instead of int.
4480 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
4481 since the 1-or-0 return value is always ignored anyway.
4482 (mmap_initialized_p):
4483 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
4484 * buffer.h, lisp.h: Adjust prototypes to match above changes.
4486 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
4488 * bidi.c: Use bool for boolean.
4489 This is a bit more readable, and makes the text segment of bidi.o
4490 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
4491 Presumably it's faster too.

4525 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
4527 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
4528 Otherwise, the compiler complains about (A?B:C) where B is void
4529 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
4530 (fontset_add): Return void, for FONTSET_ADD.
4532 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>

4536 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
4537 (dont_register_blocks) [GC_MALLOC_CHECK]:
4538 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
4539 (check_string_bytes, make_specified_string, memory_full)
4540 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
4541 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
4542 (mark_stack, valid_pointer_p, make_pure_string)
4543 (Fgarbage_collect, survives_gc_p, gc_sweep):
4544 Use bool for booleans, instead of int.
4545 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
4546 Remove unused local.
4547 * alloc.c (PURE_POINTER_P):
4548 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
4549 * editfns.c (Fformat):
4550 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
4552 * fns.c (sweep_weak_table):
4553 * lisp.h (suppress_checking, push_message, survives_gc_p)
4554 (make_pure_string, gc_in_progress, abort_on_gc):
4555 * lread.c (readchar, read1):
4556 * print.c (Fprin1_to_string):
4557 * xdisp.c (push_message):
4558 Use bool for booleans affected directly or indirectly by
4561 Make recently-introduced setters macros.
4562 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
4563 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
4564 (set_fontset_default, set_fontset_fallback): Rename from their
4565 upper-case counterparts, and make them functions rather than macros.
4566 This is more consistent with the other recently-introduced setters.
4567 These don't need to be inline, since they're local.
4569 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
4571 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in

4574 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4576 * lisp.h (vcopy): Use memcpy rather than our own loop.
4577 This fixes a performance regression introduced by the recent
4578 addition of vcopy. This means 'vcopy' will need to be modified
4579 for a copying collector, but that's OK. Also, tighten the
4580 checking in the assertion.
4582 2012-08-21 Eli Zaretskii <eliz@gnu.org>
4584 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
4585 components for RTL text (Bug#11860). Adjust X-OFFSET of each
4586 non-base glyph for the width of the base character, according to
4587 what x_draw_composite_glyph_string_foreground expects.
4588 Generate WADJUST value according to composition_gstring_width's
4589 expectations, to produce correct width of the composed character.
4590 Reverse the sign of the DU offset produced by ScriptPlace.
4592 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4594 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.

4615 buffer to the specified position.
4617 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>

4620 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
4621 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
4622 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
4625 2012-08-20 Glenn Morris <rgm@gnu.org>
4627 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
4628 Don't assume that `ln -f' works.
4630 2012-08-20 Eli Zaretskii <eliz@gnu.org>
4632 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
4633 and later about non-assignments with no effect. See discussion at
4634 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
4637 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
4639 Inline setter functions for Lisp_Objects slots of struct specbinding.
4640 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
4643 2012-08-20 Martin Rudalics <rudalics@gmx.at>
4645 * window.c (select_window): Always make selected window's buffer
4648 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>

4651 * category.h (CATEGORY_DOCSTRING): Use AREF.
4652 (SET_CATEGORY_DOCSTRING): Use ASET.
4653 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
4655 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
4657 Inline setter functions for hash table members.
4658 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
4659 (set_hash_hash, set_hash_index): Rename with _slot suffix.
4660 (set_hash_key_and_value, set_hash_index, set_hash_next)
4661 (set_hash_hash): New functions.
4662 * charset.c, fns.c: Adjust users.
4664 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
4666 Inline getter and setter functions for per-buffer values.

4670 * buffer.c, data.c: Adjust users.
4672 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
4674 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
4676 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
4678 Rely on <config.h> + <unistd.h> to declare 'environ',
4679 as gnulib does this if the system doesn't.
4680 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
4681 Remove declaration. MS-Windows declares it on stdlib.h which is
4682 included by conf_post.h.
4683 * emacs.c (environ) [DOUG_LEA_MALLOC]:
4684 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
4685 * vm-limit.c: Include <unistd.h>, for 'environ'.
4687 * unexaix.c, unexcoff.c: Include "mem-limits.h".
4688 (start_of_data): Remove decl; mem-limits.h provides it.
4690 * xdisp.c (handle_invisible_prop): Make it a bit faster
4691 and avoid a gcc -Wmaybe-uninitialized diagnostic.
4693 2012-08-19 Chong Yidong <cyd@gnu.org>
4695 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
4698 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>

4703 * data.c (set_internal): Don't use set_blv_found.
4704 (Fkill_local_variable): Likewise.
4706 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
4708 * nsfont.m (ns_ascii_average_width): Ensure the string
4709 ascii_printable is initialized with a null-terminated character
4710 array. Otherwise, it can contain undesired extra characters.
4712 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
4714 port new setting code to Sun C 5.8 2005/10/13
4715 * chartab.c, lisp.h (char_table_set, char_table_set_range):
4716 Return void, not Lisp_Object. Otherwise, the compiler
4717 complains about (A?B:C) where B is void and C is Lisp_Object
4718 when compiling CHAR_TABLE_SET, due to the recent change to
4719 the API of sub_char_table_set_contents.
4721 2012-08-18 Chong Yidong <cyd@gnu.org>
4723 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE

4880 'parent' for two different things.

4894 directly-specified attributes.
4895 (merge_face_ref): Recognize :font.
4897 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>

4944 Use C-locale tests instead of locale-specific tests for character
4945 types, since we want the ASCII interpretation here, not the
4946 interpretation suitable for whatever happens to be the current locale.

5551 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
5552 * w32.c (init_environment): Change the default values of many
5553 environment variables in dflt_envvars[] to NULL, to avoid pushing
5554 them into environment when they were not already defined.
5555 Remove the code that deletes site-lisp subdirectories from the default
5556 value of EMACSLOADPATH, as it is no longer needed.
5557 (check_windows_init_file): Now external, not static.
5558 Use Vload_path as is, without adding anything, as this function is now
5559 called when Vload_path is already set up.
5561 * w32.h (check_windows_init_file): Add prototype.
5563 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

5569 any, in the DEFALT argument into the root of the Emacs build or
5570 installation tree, as appropriate.
5572 * callproc.c (init_callproc_1): Call decode_env_path instead of
5573 doing its equivalent by hand.
5574 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
5575 the code that sets Vexec_path run on MS-Windows.
5577 * lread.c (init_lread): Add comments to #ifdef's.
5579 * msdos.c (dos_set_window_size, IT_update_begin)

5589 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
5591 Remove unnecessary casts involving pointers.
5592 These casts are no longer needed now that we assume C89 or later,
5593 since they involve casting to or from void *.

5595 (make_pure_float, make_pure_vector):
5596 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

5605 (x_get_window_property, x_get_window_property_as_lisp_data):
5606 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
5607 Remove unnecessary pointer casts.
5608 * alloc.c (record_xmalloc): New function.
5609 * lisp.h (record_xmalloc): New decl.
5610 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
5611 more like a function. This is because the pointer cast is not
5612 needed. All uses changed.
5613 * print.c (print_string, print_error_message): Avoid length recalc.
5615 Improve fix for macroexp crash with debugging (Bug#12118).
5616 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
5617 ARRAY_MARK_FLAG when checking subscripts, because ASET is
5618 not supposed to be invoked from the garbage collector.
5619 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
5620 (gc_aset): New function, which is like ASET but can be
5621 used in the garbage collector.
5622 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

5634 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
5635 (map_w32_filename): Improve commentary. Simplify switch.
5636 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
5637 headers (most versions of MinGW w32api don't).
5638 (get_security_info, create_symbolic_link)
5639 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
5641 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks

5646 have the required privileges.
5647 (get_file_security_desc_by_name): Rename from

5650 with addition of handling of symlinks and support for 'lstat'.
5651 If possible, get file's attributes and security information by
5652 handle, not by name. Produce S_IFLNK bit for symlinks, when
5653 called from 'lstat'.
5654 (stat, lstat): New functions, call 'stat_worker'.
5655 (symlink, readlink, careadlinkat): Rewritten to create and resolve
5656 symlinks when the underlying filesystem supports them.
5658 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
5660 Fix macroexp crash on Windows with debugging (Bug#12118).
5661 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
5662 checking subscripts; problem introduced with the recent
5663 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
5664 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
5665 since it's used in non-static inline functions now.
5667 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
5668 Don't assume buffer size fits in 'int'. Remove unused local.
5670 Use C99-style 'extern inline' if available.

5685 * category.c (CATEGORY_INLINE):
5686 * character.c (CHARACTER_INLINE):
5687 * charset.c (CHARSET_INLINE):
5688 * composite.c (COMPOSITE_INLINE):
5689 * dispnew.c (DISPEXTERN_INLINE):
5690 * sysdep.c (SYSTIME_INLINE):
5691 Define to EXTERN_INLINE, so that the corresponding functions
5692 are compiled into code.
5693 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
5694 (INLINE_HEADER_END): New macros.
5695 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

5715 hard-coding the path separator.
5717 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
5719 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
5720 This how ASET and AREF are supposed to work, and makes
5721 it easier to think about future improvements. See
5722 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
5723 * charset.h (set_charset_attr): New function.

6215 the fix for 12036 would have avoided some of the problems noted in

6227 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
6228 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
6229 not be usable in #if. This simplifies things.
6231 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
6233 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

6240 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
6241 Adjust to changes in lisp.h and emacs.c, by using

6244 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of

6248 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
6249 instead of gdb_array_mark_flag.
6250 (xboolvector): Get size from $->size, not $->header.size.
6251 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
6252 (xreload, hook-run, hookpost-run): Remove.
6253 * emacs.c: Include <verify.h>.
6254 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
6255 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
6257 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
6258 (gdb_USE_LSB_TAG): New enum constants.
6259 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

6262 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these

6267 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
6268 more convenient now. All uses changed.
6269 (VALMASK) [USE_LSB_TAG]: Also define in this case.

6272 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

6277 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
6279 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,

7151 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
7152 Prefer snprintf to strncpy.
7153 * nsterm.m (ns_term_init):
7154 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
7155 * nsterm.m (ns_term_init):
7156 Avoid the need for strncpy, by using build_string or
7157 make_unibyte_string directly. Use dtoastr, not snprintf.
7158 * process.c (Fmake_network_process): Diagnose service names that
7159 are too long, rather than silently truncating them or creating
7160 non-null-terminated names.

7177 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
7178 where argument type is known to be a Lisp_Cons.

7191 * lisp.h (make_pure_string): Fix prototype.
7192 (build_pure_c_string): New function, defined as static inline. This
7193 provides a better opportunity to optimize away calls to strlen when
7194 the function is called with compile-time constant argument.
7195 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
7196 argument, adjust users accordingly. Use build_pure_c_string where
7198 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
7199 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
7200 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
7202 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
7204 Avoid calls to strlen in miscellaneous functions.
7205 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
7206 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
7207 * lread.c (openp): Likewise.
7209 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
7211 Avoid calls to strlen in path processing functions.
7212 * fileio.c (file_name_as_directory): Add comment. Change to add
7213 srclen argument and return the length of result. Adjust users
7215 (directory_file_name): Fix comment. Change to add srclen argument,
7216 swap 1st and 2nd arguments to obey the common convention.
7217 Adjust users accordingly.
7218 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
7220 2012-07-10 Glenn Morris <rgm@gnu.org>
7222 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
7223 Move PENDING_OUTPUT_COUNT definition to configure.
7225 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
7226 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
7227 * s/gnu.h (DATA_START): Move definitions to configure.
7229 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
7230 We include usg5-4-common.h, which defines them both.
7232 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
7233 O_RDONLY already includes it).
7235 Stop ns builds setting the EMACSLOADPATH environment variable.
7236 * nsterm.m (ns_load_path): Rename from ns_init_paths.
7237 Now it does not set EMACSLOADPATH, just returns the load-path string.
7238 * nsterm.h: Update accordingly.
7239 * lread.c [HAVE_NS]: Include nsterm.h.
7240 (init_lread) [HAVE_NS]: Use ns_load_path.
7241 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
7243 2012-07-09 Glenn Morris <rgm@gnu.org>
7245 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
7246 since the included bsd-common.h does so.
7248 Stop ns builds setting the EMACSPATH environment variable.
7249 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
7250 (ns_init_paths): Do not set EMACSPATH.
7251 * nsterm.h (ns_exec_path): Add it.
7252 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
7255 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
7257 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
7259 * process.c (wait_reading_process_output): 'waitchannels' was unset
7260 when read_kbd || !NILP (wait_for_cell); fix this.
7262 Add GCC-style 'const' attribute to functions that can use it.
7263 * character.h (char_resolve_modifier_mask):
7264 * keyboard.h (make_ctrl_char):
7265 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
7266 (init_character_once, next_almost_prime, init_fns, init_image)
7267 (flush_pending_output, init_sound):

7272 Declare the dummy function with ATTRIBUTE_CONST.
7273 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
7274 Add decls with ATTRIBUTE_CONST.
7276 Minor improvements to make_formatted_string.
7277 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
7278 where int is good enough, as vsprintf returns an int.
7279 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
7281 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7283 Use make_formatted_string to avoid double length calculation.
7284 * lisp.h (make_formatted_string): New prototype.
7285 * alloc.c (make_formatted_string): New function.
7286 * buffer.c (Fgenerate_new_buffer_name): Use it.
7287 * dbusbind.c (syms_of_dbusbind): Likewise.
7288 * editfns.c (Fcurrent_time_zone): Likewise.
7289 * filelock.c (get_boot_time): Likewise.
7290 * frame.c (make_terminal_frame, set_term_frame_name)
7291 (x_report_frame_params): Likewise.
7292 * image.c (gs_load): Likewise.
7293 * minibuf.c (get_minibuffer): Likewise.

7306 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
7308 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7310 Move marker debugging code under MARKER_DEBUG.
7311 * marker.c (MARKER_DEBUG): Move marker debugging code under
7312 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
7313 for bootstrap with --enable-checking (~3x slowdown reported
7314 by Juanma Barranquero <lekktu@gmail.com>).
7315 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
7317 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
7319 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
7320 See <http://bugs.gnu.org/11825#29>.
7322 2012-07-08 Eli Zaretskii <eliz@gnu.org>
7324 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
7325 has no font, use the frame's font. (Bug#11813)
7326 (display_line): Add commentary about displaying truncation glyphs
7328 (produce_special_glyphs): Move here from term.c.
7330 * term.c (produce_special_glyphs): Move to xdisp.c.
7332 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
7335 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
7337 * xdisp.c (display_line): Avoid warning about implicit declaration
7340 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
7342 * lisp.h: Remove empty conditional.
7344 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
7346 * lread.c (load_path_check): Now static.
7348 Fix some minor --with-ns problems found by static checking.
7349 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
7350 (x_set_font) [!HAVE_X_WINDOWS]:
7351 * image.c (xpm_load_image) [HAVE_NS]:
7352 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
7353 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
7354 Remove unused local.
7355 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
7356 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
7357 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
7358 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
7359 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
7360 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
7361 Fix pointer signedness problem.
7362 * xfaces.c (FRAME_X_FONT_TABLE):
7363 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
7365 2012-07-07 Glenn Morris <rgm@gnu.org>
7367 * lread.c (load_path_check): New function, split from init_lread.
7368 (init_lread): Reorganize. Motivation:
7369 If EMACSLOADPATH is set, check/warn about that rather than the
7370 defaults, which we are not going to use. Hence we can remove
7371 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
7372 Don't warn if site-lisp directories are missing.
7373 If not installed, start from a blank load-path, since
7374 PATH_LOADSEARCH refers to the eventual installation directories.
7376 2012-07-07 Eli Zaretskii <eliz@gnu.org>
7378 Support truncation and continuation glyphs on GUI frames, when
7379 fringes are disabled. (Bug#11832)
7380 * xdisp.c (init_iterator): Get dimensions of truncation and
7381 continuation glyphs even if on GUI frames.
7382 Adjust it->last_visible_x on GUI frames when the left or right fringes,
7383 or both, are absent.
7384 (start_display, move_it_in_display_line_to): Handle the case of a
7385 GUI frame without a fringe to display continuation or truncation
7387 (insert_left_trunc_glyphs): Support GUI frames: make sure
7388 truncation glyphs overwrite enough glyphs from the current line to
7389 have sufficient space in pixels.
7390 (display_line): Support truncation and continuation glyphs on GUI
7391 frames. If some spare pixels are left on the line after inserting
7392 the truncation glyphs, fill that space with a stretch glyph of a
7393 suitably computed width.
7395 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
7396 produce_glyphs, to support GUI sessions.
7398 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
7400 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
7402 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
7404 Do not require float-time's arg to fit in time_t (Bug#11825).
7405 This works better on hosts where time_t is unsigned, and where
7406 float-time is applied to the (negative) difference between two times.
7407 * editfns.c (decode_time_components): Last arg is now double *,
7408 not int *, and means to store all the result as a double, without
7409 worrying about whether the seconds part fits in time_t.
7410 All callers changed.
7411 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
7412 All callers changed.
7413 (Ffloat_time): Do not fail merely because the specified time falls
7414 outside of time_t range.
7416 2012-07-07 Glenn Morris <rgm@gnu.org>
7418 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

7424 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
7425 Update dependencies.
7427 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
7429 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>

7433 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
7434 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
7435 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
7436 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
7438 * xfont.c (compare_font_names): Redo to omit the need for casts.
7440 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
7442 * xfns.c (Fx_change_window_property): Doc fix.
7443 * w32fns.c (Fx_change_window_property): Doc fix.
7445 * w32fns.c (Fx_window_property): Accept the same arguments as the
7446 X Windows version. Doc fix.
7447 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
7449 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
7450 Eli Zaretskii <eliz@gnu.org>
7452 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
7453 Windows-specific code from nt/config.nt moved here.
7454 Obsolete settings removed.
7456 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7458 * process.c: Avoid unnecessary calls to gettime.
7459 (wait_reading_process_output): Don't get the time of day
7460 when gobbling data immediately and not waiting, as there's no need
7461 for it in that case. This removes a FIXME.
7463 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
7465 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
7466 is defined (Bug#11768).
7468 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7470 Fix marker debugging code.
7471 * marker.c (byte_char_debug_check): Do not perform the check
7472 if buffer is not multibyte.
7473 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
7474 Call byte_char_debug_check with correct arguments.
7476 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7478 Compile marker debugging code only if ENABLE_CHECKING is defined.
7479 * marker.c (byte_char_debug_check, count_markers):
7480 Use only if ENABLE_CHECKING is defined.
7481 (byte_debug_flag): Remove.
7482 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
7483 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
7485 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7487 Avoid code repetition in marker-related functions.
7488 * marker.c (attach_marker): New function.
7489 (Fset_marker, set_marker_restricted, set_marker_both)
7490 (set_marker_restricted_both): Use it.
7491 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
7492 Consistently rename charno to charpos.
7493 (marker_position): Add eassert.
7494 (marker_byte_position): Convert to eassert.

7513 * window.c (save_window_save): Likewise.
7515 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7517 Do not use Fdelete_overlay in delete_all_overlays
7518 to avoid redundant calls to unchain_overlay.
7519 * buffer.c (drop_overlay): New function.
7520 (delete_all_overlays, Fdelete_overlay): Use it.
7521 * minibuf.c (get_minibuffer): Fix comment.
7523 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7525 Port to OpenBSD 5.1 amd64.
7526 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
7527 This is needed for OpenBSD, and should be harmless on all BSD systems.
7528 Also, include <sys/sysctl.h>, as it should be available on all
7529 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
7530 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
7531 use p_pid member, not kp_proc.pid.
7533 2012-07-06 Glenn Morris <rgm@gnu.org>
7535 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
7537 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
7539 More xmalloc and related cleanup.

7548 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
7550 Omit needless casts involving void * pointers and allocation.
7551 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
7552 as the former is more robust if P's type is changed.
7553 Prefer xzalloc to xmalloc + memset 0.
7554 Simplify malloc-or-realloc to realloc.
7555 Don't worry about xmalloc returning a null pointer.
7556 Prefer xstrdup to xmalloc + strcpy.
7557 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
7559 * keyboard.c (apply_modifiers_uncached): Prefer local array to
7560 alloca of a constant.
7562 2012-07-05 Eli Zaretskii <eliz@gnu.org>
7564 * xdisp.c (display_line): Fix horizontal pixel coordinates when
7565 hscroll is larger than the line width. Fixes long and futile
7566 looping inside extend_face_to_end_of_line (on a TTY) producing
7567 glyphs that are not needed and thrown away.
7569 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
7571 * marker.c (set_marker_restricted_both): Simplify by using

7597 * xdisp.c (window_hscroll_limited): New function.
7598 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
7599 coordinates when window's hscroll is set to insanely large
7602 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
7604 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

7665 * fileio.c (time_error_value): Check the right error number.
7666 Problem reported by Troels Nielsen in
7667 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
7669 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7671 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
7672 This should be fixed in a better way; see Eli Zaretskii in
7673 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
7674 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
7676 * fileio.c (time_error_value): Rename from special_mtime.
7677 The old name's problems were noted by Eli Zaretskii in
7678 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
7680 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
7681 This variable's comment says Emacs needs at least one GDB-visible
7682 symbol of type enum pvec_type, to work around GDB problems.
7683 The symbol's value doesn't matter.
7685 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
7686 that causes compilation to fail on pre-C99 compilers.
7688 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
7690 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

7693 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
7695 * buffer.c (init_buffer_once): Fix initialization of
7696 headers for buffer_defaults and buffer_local_symbols.
7697 Reported by Juanma Barranquero <lekktu@gmail.com>.

7701 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
7702 * lisp.h (enum pvec_type): Use fewer bits.
7703 (PSEUDOVECTOR_SIZE_BITS): New constant.
7704 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
7705 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
7706 change in pvec_type.
7707 (PSEUDOVECTOR_TYPEP): New macro.
7708 (TYPED_PSEUDOVECTORP): Use it.
7709 * fns.c (internal_equal): Adapt code to extract pvectype.

7713 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
7714 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
7715 (sweep_vectors): Use it. Use local var `total_bytes' instead of
7716 abusing vector->header.next.nbytes.
7717 (live_vector_p): Use PVEC_TYPE.
7718 (mark_object): Adapt code to extract pvectype. Use switch.
7720 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7722 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
7723 Tighten new eassert a bit.
7725 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
7727 Fix compilation with --enable-gcc-warnings and -O1
7729 * doprnt.c (doprnt): Change type of tem to int, initialize
7730 to avoid compiler warning. Add eassert.
7731 * search.c (simple_search): Initialize match_byte to avoid
7732 compiler warning. Add eassert.
7734 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7736 Avoid weird behavior with large horizontal scrolls.
7737 Without this change, for example, large hscroll values would
7738 mess up Emacs's display on Fedora 15 x86, presumably due to
7739 overflows in int calculations in the display code.
7740 Also, if buffers had long lines, Emacs would freeze.
7741 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
7742 (set_window_hscroll): New function, containing the old guts of
7743 Fset_window_hscroll. Return the clipped value.
7744 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
7745 This avoids the need to check against PTRDIFF_MAX.
7747 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
7749 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
7751 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
7753 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7755 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
7756 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
7757 since GCC 4.4.6 issues a bogus warning for them.
7759 Fix bugs in file timestamp newness comparisons.
7760 * fileio.c (Ffile_newer_than_file_p):
7761 * lread.c (Fload): Use full timestamp resolution of files,
7762 not just the 1-second resolution, so that files that are only
7763 slightly newer still count as newer.
7764 * fileio.c (Ffile_newer_than_file_p): Don't assume file
7765 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
7767 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
7769 * fileio.c: Improve handling of file time marker. (Bug#11852)
7770 (special_mtime): New function.
7771 (Finsert_file_contents, Fverify_visited_file_modtime):
7772 Use it to set special mtime values consistently.
7774 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
7776 * fileio.c (Finsert_file_contents): Properly handle st_mtime
7777 marker for non-existing file. (Bug#11852)
7779 2012-07-03 Glenn Morris <rgm@gnu.org>
7781 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
7782 and did not make it into globals.h).
7784 2012-07-03 Tom Tromey <tromey@redhat.com>
7786 * window.c (Fset_window_margins, Fset_window_fringes)

7822 2012-07-03 Glenn Morris <rgm@gnu.org>
7824 * lisp.h (Frandom): Make it visible to C.
7825 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
7826 buffer for invisible buffers. (Bug#1229)
7828 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7830 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
7831 values which aren't power of 2.
7832 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
7833 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
7836 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
7838 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
7840 * alloc.c (mark_object): Revert part of last patch to use `switch'.
7842 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7844 * alloc.c (allocate_vector_block): Remove redundant
7845 calls to mallopt if DOUG_LEA_MALLOC is defined.
7846 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
7847 avoid calls to mallopt if zero_vector is returned.
7849 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7851 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
7852 is enabled, avoid dereferencing NULL current_sblock if
7855 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7857 Cleanup basic buffer management.
7858 * buffer.h (struct buffer): Change layout to use generic vector
7859 marking code. Fix some comments. Change type of 'clip_changed'
7860 to bitfield. Remove unused #ifndef old.
7861 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
7862 (GET_OVERLAYS_AT): Fix indentation.
7863 (for_each_per_buffer_object_at): New macro.
7864 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

7867 * alloc.c (allocate_buffer): Adjust to match new layout of
7868 struct buffer. Fix comment.
7869 (mark_overlay): New function.

7871 Lisp area of struct buffer.
7872 (mark_object): Use it. Adjust marking of misc objects
7873 and related comments.
7875 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
7877 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
7878 wrapper that is not needed because the wrapped code is a no-op (zero
7879 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
7880 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
7882 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
7884 * alloc.c (mark_buffer): Simplify. Remove prototype.
7885 (mark_object): Add comment. Reorganize marking of vector-like
7886 objects. Use CHECK_LIVE for all vector-like objects except buffers
7887 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
7888 Avoid redundant calls to mark_vectorlike for bool vectors.
7890 2012-06-30 Glenn Morris <rgm@gnu.org>
7892 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
7894 * epaths.in (PATH_SITELOADSEARCH): New.
7895 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
7896 This is rather than relying on --enable-locallisppath elements
7897 having "site-lisp" in their names. (Bug#10208#25, 11658)
7899 2012-06-30 Eli Zaretskii <eliz@gnu.org>
7901 * w32proc.c (sys_select): Accept and ignore one more argument.
7903 * w32.c (emacs_gnutls_pull): Call select with one more argument.
7905 * sysselect.h [DOS_NT]: Don't include sys/select.h.
7906 (pselect) [!MS_DOS]: Redirect to sys_select.
7908 * sysdep.c: Don't include dos.h and dosfns.h.
7910 * process.c (sys_select):
7911 * msdos.c (sys_select): Accept one more argument and ignore it.
7913 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
7914 adapt data types and code to that.
7917 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
7918 which clashes with the gnulib function of the same name.
7920 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
7922 * font.c (font_style_to_value, font_style_symbolic)
7923 (font_prop_validate_style): Add type checks for values in
7926 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
7928 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
7931 2012-06-29 Eli Zaretskii <eliz@gnu.org>
7933 * xdisp.c (try_window_id): Undo last change.
7935 * w32.c (getwd): Adjust commentary about startup_dir.
7936 (init_environment): Always call sys_access, even in non-MSVC
7937 builds. Don't chdir to the directory of the Emacs executable.
7938 This undoes code from 1997 which was justified by the need to
7939 "avoid conflicts when removing and renaming directories". But its
7940 downside was that every relative file name was being interpreted
7941 relative to the directory of the Emacs executable, which can never
7942 be TRT. In particular, it broke sys_access when called with
7943 relative file names.
7944 (sys_access): Map GetLastError to errno.
7946 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
7948 * window.h (struct window): Change type of 'fringes_outside_margins'

7952 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
7955 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
7957 * gnutls.c (emacs_gnutls_handshake):
7958 Add QUIT to make the loop interruptible.
7960 2012-06-29 Glenn Morris <rgm@gnu.org>
7962 * charset.c (init_charset): Make lack of etc/charsets fatal.
7964 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
7966 * editfns.c (region_limit): Fix type mismatch.
7968 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

7971 undefined. Convert from xassert to eassert.
7972 * nsmenu.m: Convert from xassert to eassert.
7973 * nsterm.m: Likewise.
7975 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
7977 * editfns.c (region_limit): Clip to narrowing (bug#11770).
7979 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
7981 Avoid integer overflow on scroll-left and scroll-right.
7982 * window.c (HSCROLL_MAX): New macro.
7983 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
7984 overflow when requested scroll falls outside ptrdiff_t range.
7986 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
7988 * window.h (struct window): Change type of 'hscroll',
7989 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
7990 'last_modified' and 'last_overlay_modified' to EMACS_INT.
7991 Adjust users accordingly.
7992 * xdisp.c (try_cursor_movement): Replace type check with eassert.
7993 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
7994 from EMACS_INT to ptrdiff_t.
7995 (make_window): Omit redundant initialization.
7997 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

8001 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>

8070 * alloc.c (allocate_string): Omit intervals initialization.
8071 * alloc.c (make_uninit_multibyte_string): Initialize intervals

8128 * alloc.c: Remove build_string.
8129 * lisp.h: Define build_string as static inline. This provides
8130 a better opportunity to optimize away calls to strlen when the
8131 function is called with compile-time constant argument.
8132 * image.c (imagemagick_error): Convert to build_string.
8133 * w32proc.c (sys_spawnve): Likewise.

8136 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
8138 Use sprintf return value instead of invoking strlen on result.
8139 In the old days this wasn't portable, since some sprintf
8140 implementations returned char *. But they died out years ago and
8141 Emacs already assumes sprintf returns int.
8142 Similarly for float_to_string.
8143 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

8151 Use sprintf or float_to_string result to avoid need to call strlen.
8152 * data.c (Fnumber_to_string):
8153 Use make_unibyte_string, since the string must be ASCII.
8154 * lisp.h, print.c (float_to_string): Now returns int length.
8155 * term.c (produce_glyphless_glyph):
8156 Use sprintf result rather than recomputing it.
8158 Clean out last vestiges of the old HAVE_CONFIG_H stuff.

8327 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
8329 Support higher-resolution time stamps (Bug#9000).
8330 The time stamps are only nanosecond-resolution at the C level,
8331 since that's the best that any real-world system supports now.
8332 But they are picosecond-resolution at the Lisp level, as that's
8333 easy, and leaves room for future OS improvements.
8335 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
8338 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
8339 Don't get current time unless it's needed.
8341 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
8342 now provides it if it's absent.
8343 (start_atimer): Port to higher-res time stamps.
8344 Check for time stamp overflow. Don't get current time more
8345 often than is needed.
8347 * buffer.h (struct buffer): Buffer modtime now has high resolution.
8348 Include systime.h, not time.h.
8349 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
8351 * dired.c: Include stat-time.h.
8352 (Ffile-attributes): File times now have higher resolution.
8354 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
8355 (struct image): Timestamp now has higher resolution.
8357 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
8358 has at least microseconds now. All uses removed.
8359 (update_frame, update_single_window, update_window, update_frame_1)
8360 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
8361 (duration_to_sec_usec): Remove; no longer needed.
8363 * editfns.c (time_overflow): Now extern.

8365 (float-time, Fformat_time_string, Fcurrent_time_string)
8366 (Fcurrent_time_zone): Accept and generate higher-resolution
8368 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
8369 (decode_time_components, lisp_seconds_argument): New functions.
8370 (make_time): Now static.
8371 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
8372 Report an error if the time is invalid, rather than having the caller
8375 * fileio.c: Include <stat-time.h>
8376 (Fcopy_file): Copy higher-resolution time stamps.
8377 Prefer to set the time stamp via a file descriptor if that works.
8378 (Fset_file_times, Finsert_file_contents, Fwrite_region)
8379 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
8380 (Fvisited_file_modtime, Fset_visited_file_modtime):
8381 Support higher-resolution time stamps.
8383 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
8385 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
8387 * image.c (prepare_image_for_display, clear_image_cache)
8388 (lookup_image): Port to higer-resolution time stamps.
8390 * keyboard.c (start_polling, bind_polling_period):
8391 Check for time stamp overflow.
8392 (read_char, kbd_buffer_get_event, timer_start_idle)
8393 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
8394 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
8395 Port to higher-resolution time stamps. Do not assume time_t is signed.
8396 (decode_timer): New function. Timers are now vectors of length 9,
8397 not 8, to accommodate the picosecond component.
8398 (timer_check_2): Use it.
8400 * nsterm.m (select_timeout, timeval_subtract): Remove.
8401 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
8402 as they're a bit more accurate and handle overflow better.
8403 (ns_select): Change prototype to be compatible with pselect.
8404 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
8405 * nsterm.h (ns_select): Adjust prototype.
8407 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
8408 us-resolution time stamps.
8409 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
8411 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
8413 * lisp.h (time_overflow): New decl.
8414 (wait_reading_process_output): First arg is now intmax_t, not int,
8415 to accommodate larger waits.
8417 * process.h (struct Lisp_Process.read_output_delay):
8418 Now counts nanoseconds, not microseconds.
8419 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
8421 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
8422 (wait_reading_process_output):
8423 Port to ns-resolution time stamps.
8424 (Faccept_process_output, wait_reading_process_output):
8425 Check for time stamp overflow. Do not assume time_t is signed.
8426 (select_wrapper): Remove; we now use pselect.
8427 (Fprocess_attributes): Now generates ns-resolution time stamps.
8429 * sysdep.c: Include utimens.h. Don't include utime.h
8430 or worry about struct utimbuf; gnulib does that for us now.
8431 (gettimeofday): Remove; gnulib provides a substitute.
8432 (make_timeval): New function.
8433 (set_file_times): Now sets ns-resolution time stamps.
8434 New arg FD; all uses changed.
8435 (time_from_jiffies, ltime_from_jiffies, get_up_time)
8436 (system_process_attributes):
8437 Now returns ns-resolution time stamp. All uses changed.
8438 Check for time stamp overflow.
8440 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
8441 provides a substitute now.
8443 * systime.h: Include timespec.h rather than sys/time.h and time.h,
8444 since it guarantees struct timespec.
8445 (EMACS_TIME): Now struct timespec, so that we can support
8446 ns-resolution time stamps.
8447 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
8448 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
8449 (EMACS_USECS): Remove.
8450 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
8451 so multiply the arg by 1000 before storing it.
8452 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
8454 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
8455 Port to ns-resolution time stamps.
8456 (EMACS_TIME_NEG_P): Remove; replaced by....
8457 (EMACS_TIME_SIGN): New macro.
8458 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
8459 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
8460 (set_file_times, make_time, lisp_time_argument): Adjust signature.
8461 (make_timeval, make_lisp_time, decode_time_components): New decls.
8462 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
8463 that it mishandled time_t overflow. You can't compare by subtracting!
8464 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
8465 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
8467 * term.c: Include <sys/time.h>.
8468 (timeval_to_Time): New function, for proper overflow wraparound.

8471 * undo.c (record_first_change): Support higher-resolution time stamps
8473 (Fprimitive_undo): Use them when restoring time stamps.
8475 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
8476 (w32_get_internal_run_time):
8477 Port to higher-resolution Emacs time stamps.
8478 (ltime): Now accepts single 64-bit integer, as that's more convenient
8481 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
8483 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
8484 for compatibility with pselect. Support ns-resolution time stamps.
8486 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
8488 * xselect.c (wait_for_property_change, x_get_foreign_selection):
8489 Check for time stamp overflow, and support ns-resolution time stamps.
8491 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
8492 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
8493 (timeval_subtract): Remove; no longer needed.
8494 (XTflash, XTring_bell, x_wait_for_event):
8495 Port to ns-resolution time stamps. Don't assume time_t is signed.
8497 2012-06-22 Chong Yidong <cyd@gnu.org>

8501 2012-06-22 Eli Zaretskii <eliz@gnu.org>
8503 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
8504 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
8505 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
8506 staticidx goes up to 1597 out of 1600 = 0x640.)
8508 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
8510 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
8511 Otherwise, the umask might be mistakenly 0 while handling input signals.
8513 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
8515 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

8522 access to `contents' member of Lisp_Vector objects with AREF and ASET
8525 2012-06-19 Chong Yidong <cyd@gnu.org>
8527 * frame.c (delete_frame): When selecting a frame on a different
8528 text terminal, do not alter the terminal's top-frame.

8532 (unwind_format_mode_line): Restore them.
8533 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
8535 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
8536 since tty frames can be explicitly named.
8537 (prepare_menu_bars): Likewise.
8539 * term.c (Ftty_top_frame): New function.
8541 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

8544 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
8545 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
8546 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
8547 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
8548 (METER_1, METER_2): Simplify.
8550 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
8552 * data.c (Fdefalias): Return `symbol' (bug#11686).
8554 2012-06-18 Martin Rudalics <rudalics@gmx.at>
8556 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
8557 gets killed during executing of this function (Bug#11665).
8558 Try to always return Qt when the buffer has been actually killed.
8559 (Vkill_buffer_query_functions): In doc-string say that functions
8560 run by this hook should not change the current buffer.
8562 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
8564 Fix recently-introduced process.c problems found by static checking.
8565 * process.c (write_queue_push, write_queue_pop, send_process):

8568 (send_process): Remove unused local.
8570 2012-06-17 Chong Yidong <cyd@gnu.org>

8573 frames that are not on top.
8575 2012-06-17 Troels Nielsen <bn.troels@gmail.com>
8577 * process.c (make_process): Initialize write_queue.
8578 (write_queue_push, write_queue_pop): New functions.

8582 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
8584 * lisp.h (eassert): Assume C89 or later.
8585 This removes the need for CHECK.
8586 (CHECK): Remove. Its comments about always evaluating its
8587 argument were confusing, as 'eassert' typically does not evaluate
8590 * coding.c (produce_chars): Use ptrdiff_t, not int.
8592 * xterm.c (x_draw_underwave): Check for integer overflow.
8593 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

8778 code works fine either way, and efficiency is not a concern here,
8779 as the union type is for debugging, not for production.
8780 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
8781 Use an inline function on all platforms when using the union type,
8782 since this is simpler and 'static inline' can be used portably
8784 (LISP_INITIALLY_ZERO): New macro.
8785 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.

8926 * doprnt.c (doprnt): Truncate multibyte char correctly.
8927 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
8928 would mishandle a string argument "Xc" if X was a multibyte
8929 character of length 2: it would truncate after X's first byte
8930 rather than including all of X.

9004 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
9005 fields from Lisp_Object to bitfield. Adjust users accordingly.

9013 and 'double' in a couple of places.
9015 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9017 * xdisp.c (handle_stop): Detect whether we have overlay strings
9018 loaded by testing it->current.overlay_string_index to be
9019 non-negative, instead of checking whether n_overlay_strings is
9020 positive. (Bug#11587)

9030 * search.c (search_buffer): Remove calls to
9031 r_alloc_inhibit_buffer_relocation, as it is now called by
9032 maybe_unify_char, which was the cause of relocation of buffer text
9035 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9037 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
9038 for the duration of call to load_charset, to avoid problems with
9039 callers of maybe_unify_char that access buffer text through C
9042 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
9043 decrement the inhibition flag, instead of just setting or

9049 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.

9053 (gray_bitmap_bits): Remove; no longer needed.

9093 * lread.c (read1): Tiny simplification.
9095 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
9097 Do not create empty overlays with the evaporate property (Bug#9642).
9098 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
9099 Bug#9642, but explicitly check that the buffer the overlay would
9100 be moved to is live and rearrange lines to make sure that errors
9101 will not put the overlay in an inconsistent state.
9102 (Fdelete_overlay): Cosmetics.
9104 2012-05-28 Eli Zaretskii <eliz@gnu.org>
9106 * w32term.c (my_bring_window_to_top): New function.
9107 (x_raise_frame): Use handle returned by DeferWindowPos, which
9108 could be different from the original one.

9112 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
9113 by calling BringWindowToTop.
9115 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
9116 (WM_EMACS_END): Increase by one.
9118 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
9120 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
9121 This avoids undefined behavior that might cause the eassert
9122 to not catch an out-of-range value.
9124 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
9126 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
9127 Update dependencies.

9136 when referring to sectname field in printf format.
9138 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
9140 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
9141 Only r_alloc_inhibit_buffer_relocation needed to be added;
9142 the others were already declared.
9144 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
9145 before checking whether it's out of range. Put the check inside
9147 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
9149 2012-05-27 Ken Brown <kbrown@cornell.edu>
9151 * callproc.c (Fcall_process): Restore a line that was accidentally
9152 commented out in the 2011-02-13 change (bug#11547).
9154 2012-05-27 Eli Zaretskii <eliz@gnu.org>
9156 * lisp.h [REL_ALLOC]: Add prototypes for external functions
9157 defined on ralloc.c.
9159 * buffer.c [REL_ALLOC]: Remove prototypes of
9160 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
9161 they are now on lisp.h.
9163 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
9165 * search.c (search_buffer): Use it to inhibit relocation of buffer
9166 text while re_search_2 is doing its job, because re_search_2 is
9167 passed C pointers to buffer text. (Bug#11519)
9169 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
9172 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
9173 state after an additional call to move_it_in_display_line_to, keep
9174 the values of it->max_ascent and it->max_descent found for the
9176 (pos_visible_p): Revert the comparison against bottom_y to what it
9177 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
9180 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
9182 Fix coding-related core dumps with gcc -ftrapv.
9183 The code was computing A - B, where A and B are pointers, and B is
9184 random garbage. This can lead to core dumps on platforms that
9185 have special pointer registers, and it also leads to core dumps on
9186 x86-64 when compiled with gcc -ftrapv. The fix is to compute
9187 A - B only when B is initialized properly.
9188 * coding.c (coding_set_source, coding_set_destination): Return void.
9189 (coding_change_source, coding_change_destinations): New functions,
9190 with the old behaviors of coding_set_source and coding_set_destination.
9191 All callers that need an offset changed to use these new functions.
9193 2012-05-26 Glenn Morris <rgm@gnu.org>
9195 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
9197 2012-05-26 Eli Zaretskii <eliz@gnu.org>
9199 Extend mouse support on W32 text-mode console.
9200 * xdisp.c (draw_row_with_mouse_face):
9201 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
9203 * w32console.c: Include window.h.
9204 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
9206 (initialize_w32_display): Initialize mouse-highlight data.
9208 * w32inevt.c: Include termchar.h and window.h.
9209 (do_mouse_event): Support mouse-autoselect-window. When the mouse
9210 moves, call note_mouse_highlight. If help_echo changed, call
9211 gen_help_event to produce help-echo message in the echo area.
9212 Call clear_mouse_face if mouse_face_hidden is set in the mouse
9215 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
9217 * lread.c (read1): Simplify slightly to avoid an overflow warning
9218 with GCC 4.7.0 on x86-64.
9220 2012-05-26 Eli Zaretskii <eliz@gnu.org>
9222 * bidi.c (bidi_mirror_char): Revert last change: an int is
9223 definitely wide enough here.
9225 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
9227 Fix integer width and related bugs (Bug#9874).

9235 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
9237 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9238 (allocate_pseudovector):
9239 Use int, not EMACS_INT, where int is wide enough.
9240 (inhibit_garbage_collection, Fgarbage_collect):
9241 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9242 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
9243 int might not be wide enough.
9244 (bidi_cache_search, bidi_cache_find, bidi_init_it)

9248 (bidi_level_of_next_char, bidi_move_to_visually_next):
9249 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9250 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
9251 (Fkill_buffer, Fset_buffer_major_mode)

9258 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
9259 (Foverlay_recenter, last_overlay_modification_hooks_used)
9260 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
9261 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9262 (validate_region): Omit unnecessary test for b <= e,
9263 since that's guaranteed by the previous test.
9264 (adjust_overlays_for_delete): Avoid pos + length overflow.
9265 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
9266 (report_overlay_modification):
9267 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9268 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
9269 Omit pointer cast, which isn't needed anyway, and doesn't work
9270 after the EMACS_INT -> ptrdiff_t change.
9271 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
9272 * buffer.h: Adjust decls to match defn changes elsewhere.

9277 not int, to avoid needless 32-bit limit on 64-bit hosts.
9278 (exec_byte_code): Use tighter memory-full test, one that checks
9279 for alloca overflow. Don't compute the address of the object just
9280 before an array, as that's not portable. Use EMACS_INT, not
9281 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
9282 * callint.c (Fcall_interactively):
9283 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

9294 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
9295 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9296 (casify_object): Avoid integer overflow when overallocating buffer.
9297 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
9298 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
9299 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
9300 * category.h (CATEGORYP): Don't assume arg is nonnegative.
9301 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
9302 integers are now checked earlier. All uses replaced with XINT.
9304 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9305 For CCL_MapSingle, check that content and value are in int range.
9306 (ccl_driver, Fregister_code_conversion_map):
9307 Check that Vcode_version_map_vector is a vector.
9308 (resolve_symbol_ccl_program): Check that vector header is in range.
9309 Always copy the vector, so that we can check its contents reliably
9310 now rather than having to recheck each instruction as it's being
9311 executed. Check that vector words fit in 'int'.
9312 (ccl_get_compiled_code, Fregister_ccl_program)
9313 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
9314 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
9315 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
9316 contents are in range.
9317 (Fccl_execute_on_string): Check that status is in range.
9318 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
9319 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
9320 Accept and return EMACS_INT, not int, because callers can pass values
9322 (c_string_width, strwidth, lisp_string_width, chars_in_text)

9325 (str_as_unibyte, str_to_unibyte, string_count_byte8)
9326 (string_escape_byte8, Fget_byte):
9327 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9328 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
9329 avoid mishandling large integers.
9330 * character.h: Adjust decls to match defn changes elsewhere.

9339 (Fdefine_charset_internal): Check ranges here, more carefully.
9340 Don't rely on undefined behavior with signed left shift overflow.
9341 Don't assume unsigned int fits into fixnum, or that fixnum fits
9342 into unsigned int. Don't require max_code to be a valid fixnum;
9343 that's not true for gb10830 4-byte on a 32-bit host. Allow
9344 invalid_code to be a cons, for the same reason. Require code_offset
9345 to be a character. Avoid int overflow if max_char is close
9347 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
9348 this is intended anyway and avoids some undefined behavior.
9349 (load_charset_map): Pass unsigned, not int, as 2nd arg of
9350 INDEX_TO_CODE_POINT, as that's what it expects.
9351 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
9352 * charset.h (DECODE_CHAR): Return int, not unsigned;
9353 this is what was intended anyway, and it avoids undefined behavior.
9354 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
9355 integer-overflow issues.
9356 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
9357 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
9358 where the argument is EMACS_INT, and this behavior is not intended.
9359 * chartab.c (Fmake_char_table, Fset_char_table_range)
9360 (uniprop_get_decoder, uniprop_get_encoder):
9361 Don't assume fixnum fits in int.
9362 * cmds.c (move_point): New function, that does the gist of
9363 Fforward_char and Fbackward_char, but does so while checking
9364 for integer overflow more accurately.
9365 (Fforward_char, Fbackward_char): Use it.
9366 (Fforward_line, Fend_of_line, internal_self_insert)
9367 (internal_self_insert):
9368 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9369 Fix a FIXME, by checking for integer overflow when calculating
9370 target_clm and actual_clm.

9405 Don't access memory outside of the args array.
9406 (Fdefine_coding_system_internal): Check for charset-id overflow.

10159 (report_error, report_error_1, make_hdr, copy_sym)
10160 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
10161 Make arguments const char *, not char *, to avoid violations of C

10164 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10166 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
10167 already have overlays loaded.
10168 (handle_single_display_spec): Before returning without displaying
10169 fringe bitmap, synchronize the bidi iterator with the main display
10170 iterator, by calling iterate_out_of_display_property.
10171 (iterate_out_of_display_property): Detect buffer iteration by
10172 testing that it->string is a Lisp string.
10173 (get_next_display_element): When the current object is exhausted,
10174 and there's something on it->stack, call set_iterator_to_next to
10175 proceed with what's on the stack, instead of returning zero.
10176 (set_iterator_to_next): If called at the end of a Lisp string,
10177 proceed to consider_string_end without incrementing string
10178 position. Don't increment display vector index past the end of

10180 (pos_visible_p): Don't report a position visible when move_it_to
10181 stopped at the last line of window, which happens to be scanned
10182 backwards by the bidi iteration. (Bug#11464)
10184 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10186 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
10187 and right-margin display specs even if the spec is invalid or we
10188 are on a TTY, and thus unable to display on the fringes.
10189 That's because the text with the property will not be displayed anyway,
10190 so we need to signal to the caller that this is a "replacing"
10191 display spec. This fixes display when the spec is invalid or we
10194 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
10196 * unexaix.c (make_hdr): Fix typo in prototype.

10212 2012-05-12 Glenn Morris <rgm@gnu.org>
10214 * Makefile.in (MKDIR_P): New, set by configure.
10215 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
10217 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
10219 Remove unused function hourglass_started.
10220 * dispextern.h (hourglass_started):
10221 * w32fns.c (hourglass_started):
10222 * xdisp.c (hourglass_started): Remove.
10224 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
10226 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
10227 Update dependencies.
10229 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
10231 * xgselect.c (xg_select): Put maxfds+1 into a var.
10232 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
10234 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
10236 2012-05-10 Dave Abrahams <dave@boostpro.com>
10238 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
10239 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
10241 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
10243 * dbusbind.c (xd_registered_buses): New internal Lisp object.
10244 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
10245 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
10246 Initialize xd_registered_buses.
10248 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
10250 Untag more efficiently if USE_LSB_TAG.
10251 This is based on a proposal by YAMAMOTO Mitsuharu in
10252 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
10253 For an admittedly artificial (nth 8000 longlist) benchmark on
10254 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
10255 Emacs's overall text size by 1%.
10256 * lisp.h (XUNTAG): New macro.
10257 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
10258 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
10259 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
10260 * eval.c (Fautoload):
10261 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
10262 * frame.h (XFRAME): Use XUNTAG.
10264 Port recent dbusbind.c changes to 32-bit --with-wide-int.
10265 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
10266 Remove unportable assumptions about print widths of types like
10268 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
10269 intptr_t when converting between pointer and integer, to avoid GCC
10270 warnings about wrong width.
10272 2012-05-09 Eli Zaretskii <eliz@gnu.org>
10274 * w32proc.c (new_child): Force Windows to reserve only 64KB of
10275 stack for each reader_thread, instead of defaulting to 8MB
10276 determined by the linker. This avoids failures in creating
10277 subprocesses on Windows 7, see the discussion in this thread:
10278 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
10280 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
10282 Fix up display of the *Minibuf-0* buffer in the mini window.
10283 * keyboard.c (read_char): Don't clear the echo area if there's no
10285 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
10286 contents of *Minibuf-0*) if there's no message displayed in its stead.
10288 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
10290 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
10293 2012-05-06 Chong Yidong <cyd@gnu.org>
10295 * lisp.mk (lisp): Update.
10297 2012-05-05 Jim Meyering <meyering@redhat.com>
10299 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
10301 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
10303 * data.c (PUT_ERROR): New macro.
10304 (syms_of_data): Use it. Add new error type `user-error'.
10305 * undo.c (user_error): New function.
10306 (Fprimitive_undo): Use it.
10307 * print.c (print_error_message): Adjust print style for `user-error'.
10308 * keyboard.c (user_error): New function.
10309 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
10311 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
10313 Do not limit current-time-string to years 1000..9999.
10314 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
10315 (Fcurrent_time_string): Support any year that is supported by the
10316 underlying localtime representation. Don't use asctime, as it
10317 has undefined behavior for years outside the range -999..9999.
10319 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
10321 Fix race conditions involving setenv, gmtime, localtime, asctime.
10322 Without this fix, interrupts could mess up code that uses these
10323 nonreentrant functions, since setting TZ invalidates existing
10324 tm_zone or tzname values, and since most of these functions return
10325 pointers to static storage.
10326 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
10327 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
10328 Grow the critical sections to include not just invoking
10329 localtime/gmtime, but also accessing these functions' results
10330 including their tm_zone values if any, and any related TZ setting.
10331 (format_time_string): Last arg is now struct tm *, not struct tm **,
10332 so that the struct tm is saved in the critical section.
10333 All callers changed. Simplify allocation of initial buffer, partly
10334 motivated by the fact that memory allocation needs to be outside
10335 the critical section.
10337 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
10339 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
10340 with RESET_INTERVAL.
10342 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
10343 Remove duplicated buffer name initialization.
10345 2012-05-02 Jim Meyering <jim@meyering.net>
10347 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
10349 * xfns.c (x_window): Use xstrdup (Bug#11375).
10351 2012-05-02 Eli Zaretskii <eliz@gnu.org>
10353 * xdisp.c (pos_visible_p): If already at a newline from the
10354 display string before the 'while' loop, don't walk back the glyphs
10355 from it3.glyph_row. Solves assertion violation when the display
10356 string begins with a newline (egg.el). (Bug#11367)
10358 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
10360 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
10363 2012-05-01 Glenn Morris <rgm@gnu.org>
10365 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
10366 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
10367 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
10368 All were removed before 23.1.
10370 * dispnew.c: Remove HAVE_LIBNCURSES test;
10371 it is always true on relevant platforms.
10373 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
10374 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
10376 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
10378 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
10380 * .gdbinit (xpr): Remove checks for no longer existing misc types.
10381 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
10384 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
10386 Do not avoid creating empty evaporating overlays (Bug#9642).
10387 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
10388 That is, do not delete an evaporating overlay if it becomes
10389 empty after its bounds are adjusted to fit within its buffer.
10390 This fix caused other problems, and I'm reverting it until we get
10391 to the bottom of them.
10393 2012-04-27 Chong Yidong <cyd@gnu.org>
10395 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
10397 2012-04-27 Eli Zaretskii <eliz@gnu.org>
10399 * xdisp.c (pos_visible_p): If the window start position is beyond
10400 ZV, start the display from buffer beginning. Prevents assertion
10401 violation in init_iterator when the minibuffer window is scrolled
10402 via the scroll bar.
10404 * window.c (window_scroll_pixel_based): Likewise.
10406 2012-04-27 Chong Yidong <cyd@gnu.org>
10408 * keymap.c (where_is_internal): Doc fix (Bug#10872).
10410 2012-04-27 Glenn Morris <rgm@gnu.org>
10412 * fileio.c (Fcopy_file, Fset_file_selinux_context):
10413 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
10415 2012-04-27 Eli Zaretskii <eliz@gnu.org>
10417 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
10418 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
10420 2012-04-26 Eli Zaretskii <eliz@gnu.org>
10422 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
10423 display element, check also the underlying string or buffer
10424 character. (Bug#11341)
10426 * w32menu.c: Include w32heap.h.
10427 (add_menu_item): If the call to AppendMenuW (via
10428 unicode_append_menu) fails, disable Unicode menus only if we are
10429 running on Windows 9X/Me.
10431 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
10433 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
10434 (xgetint): Add missing shift for LSB tags.
10436 2012-04-24 Martin Rudalics <rudalics@gmx.at>
10438 * keyboard.c (read_char): Don't wipe echo area for select window
10439 events: These might get delayed via `mouse-autoselect-window'
10442 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
10444 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
10445 manipulation of :loaded-from data.
10447 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
10449 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
10450 now a cons (bug#11311).
10452 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
10454 Do not create empty overlays with the evaporate property (Bug#9642).
10455 * buffer.c (Fmove_overlay): Delete an evaporating overlay
10456 if it becomes empty after its bounds are adjusted to fit within
10457 its buffer. Without this fix, in a nonempty buffer (let ((o
10458 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
10459 yields an empty overlay that has the evaporate property, which is
10460 not supposed to happen.
10462 Fix minor GTK3 problems found by static checking.
10463 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
10464 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
10465 (struct _EmacsFixedClass, emacs_fixed_get_type):
10466 Move decls here from emacsgtkfixed.h, since they needn't be public.
10467 (emacs_fixed_get_type): Now static.
10468 (emacs_fixed_class_init): Omit unused local.
10469 (emacs_fixed_child_type): Remove; unused.

10471 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
10472 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
10473 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
10474 (EMACS_FIXED_GET_CLASS): Remove; unused.
10475 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
10477 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
10478 Problem reported by Juanma Barranquero for Windows -Wunused-function.
10480 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
10482 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
10483 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
10484 (__malloc_size_t, __malloc_ptrdiff_t):
10485 Remove. All uses removed, replaced by the definiens if needed,
10486 since we can assume C89 or better now.
10487 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
10488 (protect_malloc_state, align, get_contiguous_space)
10489 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

10494 (special_realloc, _realloc_internal_nolock, _realloc_internal)
10495 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
10496 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
10497 Define using prototypes, not old style.
10498 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
10499 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
10500 (align): Don't assume that signed integer overflow wraps around.
10501 Omit unused local var.
10502 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)

10504 Omit no-longer-needed casts.
10505 (valloc): Use getpagesize, not __getpagesize.
10506 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
10507 (struct hdr): The 'magic' member is now size_t, not unsigned long.
10509 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
10511 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
10513 Move functions from C to Lisp. Make non-blocking method calls
10514 the default. Implement further D-Bus standard interfaces.

10544 (Fdbus_method_return_internal, Fdbus_method_error_internal)
10545 (Fdbus_send_signal, Fdbus_register_service)
10546 (Fdbus_register_signal, Fdbus_register_method): Move to dbus.el.

10559 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
10560 Do not assume ptrdiff_t is the same width as 'int'.
10562 * alloc.c: Handle unusual debugging option combinations.
10563 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
10564 since the two debugging options are incompatible.
10565 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
10567 (mem_init, mem_insert, mem_insert_fixup):
10568 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

10578 (list_system_processes, system_process_attributes) [__FreeBSD__]:
10579 Use Emacs indenting style more consistently. Avoid some casts.
10580 Use 'double' consistently rather than mixing 'float' and 'double'.
10582 2012-04-21 Eduard Wiebe <usenet@pusto.de>
10584 * sysdep.c (list_system_processes, system_process_attributes):

10618 (set_cursor_from_row): If called for a mode-line or header-line
10619 row, return zero immediately.
10620 (try_cursor_movement): If inside continuation line, don't back up
10621 farther than the first row after the header line, if any.
10622 Don't consider the header-line row as "partially visible", even if
10623 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
10625 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

10661 New extern decls, to avoid calling undeclared functions.
10662 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
10663 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
10664 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
10665 (NEED_MEM_INSERT): New macro.
10666 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
10667 Remove one incorrect comment and fix another.

10681 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
10682 Remove decls. This fixes an "It stinks!".
10684 * alloc.c (which_symbols): Fix alignment issue / type clash.
10686 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
10688 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
10689 (struct Lisp_Misc_Any): Likewise.
10690 (struct Lisp_Free): Likewise.
10691 * alloc.c (union aligned_Lisp_Symbol): Define.

10701 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
10702 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
10703 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
10704 * s/netbsd.h, s/sol2-6.h:
10705 Remove definition of GC_MARK_STACK, since the default now works.
10706 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
10707 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
10708 no longer the default.
10709 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
10711 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
10713 * lread.c (lisp_file_lexically_bound_p):
10714 Fix hang at ";-*-\n" (bug#11238).
10716 2012-04-14 Eli Zaretskii <eliz@gnu.org>
10718 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row

10730 2012-04-13 Reuben Thomas <rrt@sc3d.org>
10732 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
10734 2012-04-11 Daniel Colascione <dancol@dancol.org>
10736 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
10737 against is gone. It's better to use vfork now so that when Cygwin
10738 gains a new, working vfork, we use it automatically (bug#10398).
10740 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

10758 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
10760 * w32.c (w32_delayed_load): Record the full path of the library
10761 being loaded (bug#10424).
10763 2012-04-09 Glenn Morris <rgm@gnu.org>
10765 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
10766 not just in the obarray, before snarfing them. (Bug#11036)
10768 * Makefile.in ($(leimdir)/leim-list.el):
10769 Pass EMACS rather than BUILT_EMACS.
10771 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
10773 * process.c (make_process):
10774 * process.h: Add integer `gnutls_handshakes_tried' member to

10783 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
10784 attempts per process (connection).
10786 2012-04-09 Chong Yidong <cyd@gnu.org>
10788 * eval.c (Fuser_variable_p, user_variable_p_eh)
10789 (lisp_indirect_variable): Functions deleted.
10790 (Fdefvar): Caller changed.
10792 * callint.c (Finteractive, Fcall_interactively):
10793 * minibuf.c (Fread_variable): Callers changed.
10795 2012-04-09 Eli Zaretskii <eliz@gnu.org>
10797 * xdisp.c (set_cursor_from_row): If the display string appears in
10798 the buffer at position that is closer to point than the position
10799 after the display string, display the cursor on the first glyph of
10800 the display string. Fixes cursor display when a 'display' text
10801 property immediately follows invisible text. (Bug#11094)
10803 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
10805 composite.c: use 'double' consistently
10806 * composite.c (get_composition_id): Use 'double' consistently
10807 instead of converting 'float' to 'double' and vice versa; this is
10808 easier to understand and avoids a GCC warning.
10810 2012-04-09 Glenn Morris <rgm@gnu.org>
10812 * Makefile.in: Generate leim-list with bootstrap-emacs, in
10813 preparation for dumping it with emacs. (Bug#4789)
10814 (leimdir): New variable.
10815 ($(leimdir)/leim-list.el): New rule.
10816 (emacs$(EXEEXT)): Depend on leim-list.el.

10834 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
10835 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
10836 (mark_memory): Mark Lisp_Objects only if pointers might hide in
10837 objects, as mark_maybe_pointer will catch them otherwise.
10838 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
10839 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

10848 Support building on MS-Windows with libxml2.
10850 * makefile.w32-in (OBJ2): Add xml.$(O).
10851 (GLOBAL_SOURCES): Add xml.c.
10852 ($(BLD)/xml.$(O)): New dependency list.
10854 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
10855 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
10856 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
10857 [!WINDOWSNT]: New macros.
10858 (init_libxml2_functions, libxml2_loaded_p): New functions.
10859 (parse_region): Call fn_xmlCheckVersion instead of using the macro
10860 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
10861 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
10862 Calls xmlCleanupParser only if libxml2 was loaded (or statically
10864 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
10865 Call init_libxml2_functions before calling libxml2 functions.
10866 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
10868 * emacs.c: Don't include libxml/parser.h.
10869 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
10870 xmlCleanupParser directly.
10872 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
10874 2012-04-07 Eli Zaretskii <eliz@gnu.org>
10876 * indent.c (Fvertical_motion): If there is a display string at
10877 point, use it.vpos to compute how many lines to backtrack after
10878 move_it_to point. (Bug#11133)
10880 2012-04-06 Eli Zaretskii <eliz@gnu.org>
10882 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
10883 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
10884 about subtle differences between FETCH_CHAR* and STRING_CHAR*
10885 macros related to unification of CJK characters. For the details,
10886 see the discussion following the message here:
10887 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
10889 2012-04-04 Chong Yidong <cyd@gnu.org>
10891 * keyboard.c (Vdelayed_warnings_list): Doc fix.
10893 2012-04-01 Eli Zaretskii <eliz@gnu.org>
10895 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

10903 2012-03-31 Eli Zaretskii <eliz@gnu.org>
10905 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
10906 position we get to after a call to move_it_to fails the
10907 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
10908 only if we wind up in a string from display property. (Bug#11063)
10910 * window.c (Fdelete_other_windows_internal): Invalidate the row
10911 and column information about mouse highlight, so that redisplay
10912 restores it after reallocating the glyph matrices. (Bug#7464)
10914 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
10915 string comes from a `display' text property, use the buffer
10916 position of that property as if we actually saw that position in
10918 (move_it_by_lines): Remove the assertion that
10919 "it->current_x == 0 && it->hpos == 0" which can be legitimately
10920 violated when there's a before-string at the beginning of a line.
10923 2012-03-30 Eli Zaretskii <eliz@gnu.org>
10925 * xdisp.c (append_space_for_newline): If the default face was
10926 remapped, use the remapped face for the appended newline.
10927 (extend_face_to_end_of_line): Use the remapped default face for
10928 extending the face to the end of the line.
10929 (display_line): Call extend_face_to_end_of_line when the default
10930 face was remapped. (Bug#11068)
10932 2012-03-29 Eli Zaretskii <eliz@gnu.org>
10934 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

10952 * keyboard.c (Vselection_inhibit_update_commands): New variable.
10953 (command_loop_1): Use it; inhibit selection update for

10960 2012-03-25 Kenichi Handa <handa@m17n.org>
10962 * dispextern.h (struct glyph): Change the bit length of
10963 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
10965 2012-03-24 Eli Zaretskii <eliz@gnu.org>
10967 * s/ms-w32.h (tzname): Include time.h before redirecting to

10972 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
10975 * xterm.c (XTread_socket): Only modify handling_signal if
10976 !SYNC_INPUT. (Bug#11080)
10978 2012-03-23 Eli Zaretskii <eliz@gnu.org>
10980 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
10981 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
10982 when fetching a multibyte character consumes more bytes than
10983 CHAR_BYTES returns, due to unification of CJK characters in
10984 string_char. (Bug#11073)
10986 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
10988 * process.c (wait_reading_process_output): Handle pty disconnect
10989 by refraining from sending oneself a SIGCHLD (bug#10933).
10991 2012-03-22 Chong Yidong <cyd@gnu.org>
10993 * dispextern.h (struct it): New member string_from_prefix_prop_p.

11020 2012-03-18 Eli Zaretskii <eliz@gnu.org>
11022 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
11023 that is not from display property, accept the row as a "cursor
11024 row" if one of the string's character has a non-nil `cursor'
11025 property. Fixes cursor positioning when there are newlines in
11026 overlay strings, e.g. in icomplete.el. (Bug#11035)
11028 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
11030 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
11032 2012-03-12 Chong Yidong <cyd@gnu.org>
11034 * eval.c (inhibit_lisp_code): Rename from
11035 inhibit_window_configuration_change_hook; move from window.c.
11037 * xfns.c (unwind_create_frame_1, Fx_create_frame):
11038 * window.c (run_window_configuration_change_hook)
11039 (syms_of_window): Callers changed.
11041 2012-03-11 Chong Yidong <cyd@gnu.org>

11047 2012-03-10 Chong Yidong <cyd@gnu.org>
11049 * frame.c (other_visible_frames): Don't assume the selected frame
11050 is visible (Bug#10955).
11052 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
11054 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
11056 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
11058 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
11059 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
11062 2012-03-03 Glenn Morris <rgm@gnu.org>
11064 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
11066 2012-03-02 Eli Zaretskii <eliz@gnu.org>

11069 position past the first glyph_row that ends at ZV. (Bug#10902)
11070 (redisplay_window, next_element_from_string): Fix typos in
11072 (redisplay_window): Pass to move_it_vertically the margin in
11073 pixels, not in screen lines.
11075 2012-03-02 Glenn Morris <rgm@gnu.org>
11077 * buffer.c (buffer-list-update-hook): Doc fix.
11079 2012-02-29 Eli Zaretskii <eliz@gnu.org>
11081 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
11082 push_it before setting up the iterator for the first overlay
11083 string, even if we have an empty string loaded.
11084 (next_overlay_string): If there's an empty string on the iterator
11085 stack, pop the stack. (Bug#10903)
11087 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
11089 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
11090 Suggested by Stefan Monnier in
11091 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
11092 * alloc.c (widen_to_Lisp_Object): New static function.
11093 (mark_memory): Also mark Lisp_Objects by fetching pointer words
11094 and widening them to Lisp_Objects. This would work even if
11095 USE_LSB_TAG is defined and wide integers are used, which might
11096 happen in a future version of Emacs.
11098 2012-02-25 Chong Yidong <cyd@gnu.org>
11100 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
11103 * xselect.c (Fx_selection_exists_p): Doc fix.

11110 requests in kbd_buffer, not just the next one (Bug#8869).
11112 2012-02-23 Chong Yidong <cyd@gnu.org>

11140 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
11141 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
11142 It's useless in that case, and it can cause problems on hosts
11143 that allocate halves of EMACS_INT values separately.
11144 Reported by Dan Horák. Diagnosed by Andreas Schwab in
11145 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
11146 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
11147 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
11148 it avoids undefined behavior on hosts where shifting right by more
11149 than the word width has undefined behavior.
11151 2012-02-19 Chong Yidong <cyd@gnu.org>
11153 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
11154 (Funhandled_file_name_directory, Ffile_name_as_directory)

11196 * window.c (Fdelete_window_internal): Invalidate the mouse
11197 highlight (Bug#9904).

11275 * character.c (char_width): Return EMACS_INT, not int.
11276 (char_width, c_string_width): Check for overflow when

11303 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to

11310 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
11311 first 2 arguments are identical. This makes inserting large

11766 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
11767 verifies glyph row's hash code--we have just reallocated the

11933 is set, removing the need for VIRT_ADDRESS_VARIES.
11934 (PURE_P): Use a more-efficient implementation that needs just one

11951 behave as if the cursor position were at the window margin.
11953 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
11954 and the cursor position is out of bounds, behave as if the cursor
11955 position were at the window margin. (Bug#10075)
11957 2011-11-18 Chong Yidong <cyd@gnu.org>
11959 * window.c (Fwindow_combination_limit): Make first argument

11981 compute_line_metrics.
11982 (compute_line_metrics): Call row_hash, instead of computing the
11985 * dispnew.c (verify_row_hash): Call row_hash for computing the
11986 hash code of a row, instead of duplicating code from xdisp.c.
11988 * dispextern.h (row_hash): Add prototype.
11990 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
11992 * frame.c (delete_frame): Don't delete the terminal when the last

12041 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
12042 with user-defined heap size. Bump the default size of the temacs

12046 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
12047 current_matrix and desired_matrix. (Bug#9990)
12048 (verify_row_hash) [XASSERTS]: New function.

12095 Avoid some portability problems by eschewing 'extern inline' functions.
12096 The trivial performance wins aren't worth the portability hassles; see
12097 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
12099 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

12148 This is also needed for porting to any host where GC_MARK_STACK is
12149 not GC_MAKE_GCPROS_NOOPS.
12150 (which_symbols): Use it.

12165 * xmenu.c (cleanup_widget_value_tree): New function.
12166 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

12173 (window_box_width, window_box_left, window_box_left_offset)
12174 (window_box_right, window_box_right_offset): Declare extern.
12175 Otherwise, these inline functions do not conform to C99 and
12176 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
12177 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
12178 * intervals.c (adjust_intervals_for_insertion)

12181 (static_offset_intervals): Remove.
12182 (offset_intervals): Rewrite using the old contents of
12183 static_offset_intervals. The old version didn't conform to C99
12184 because an extern inline function contained a reference to an
12185 identifier with static linkage.

12251 official. Move initialization of image_cache_refcount and
12252 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

12498 * editfns.c: Rewrite current-time-zone so that it invokes
12499 the equivalent of (format-time-string "%Z") to get the time zone name.
12500 This fixes a bug when the time zone name contains characters that
12501 need converting from the system time locale to Emacs internal format.
12502 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
12503 that patch fixed format-time-string to do the conversion, but
12504 I forgot to fix current-time-zone.
12505 (format_time_string): New function, containing most of
12506 what Fformat_time_string used to contain.
12507 (Fformat_time_string): Rewrite in terms of format_time_string.
12508 This doesn't change this function's behavior.
12509 (current-time-zone): Rewrite to use format_time_string.
12510 This fixes the bug reported by Michael Schierl in
12511 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
12512 Jason Rumney's 2007-06-07 change worked around this bug, but
12514 * systime.h (tzname, timezone): Remove no-longer-used declarations.
12516 2011-10-19 Eli Zaretskii <eliz@gnu.org>
12518 * xdisp.c (start_display): If the character at POS is displayed
12519 via a display vector, reset IT->current.dpvec_index to zero.
12520 (try_window_reusing_current_matrix): If a line ends in a display
12521 vector or the next line starts in a display vector, continue
12522 redrawing the window even though the character position of
12523 start_row was reached.
12526 2011-10-18 Chong Yidong <cyd@gnu.org>
12528 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
12529 with nobreak-char-display too.
12531 2011-10-18 Eli Zaretskii <eliz@gnu.org>
12533 Fix part 3 of bug#9771.
12534 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
12535 (bidi_resolve_neutral): Don't enter the expensive loop looking for
12536 non-neutral characters if the current character is a paragraph
12537 separator (a.k.a. Newline). This avoids running the same
12538 expensive loop twice, once when we consume the preceding newline
12539 and the other time when the line actually needs to be displayed.
12540 Avoid the loop when we see neutrals on the base embedding level
12541 following a character whose directionality is the same as the
12542 paragraph's. This avoids running the expensive loop when a line
12543 ends in a long sequence of neutrals, like control characters.
12544 Add assertion against STRONG_AL type. Slightly rearrange code
12545 that determines the type of a neutral given the first non-neutral
12547 (bidi_level_of_next_char): Set next_en_pos to zero when
12548 invalidating its info.
12550 2011-10-17 Eli Zaretskii <eliz@gnu.org>
12552 * xdisp.c (push_display_prop): Determine whether to record string
12553 or buffer position by IT->string, not by IT->method. Allow
12554 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
12555 (move_it_vertically_backward): Don't look for character position
12556 immediately after the newline when in a continuation line.
12559 2011-10-15 Martin Rudalics <rudalics@gmx.at>
12561 * window.c (coordinates_in_window): Rewrite and delabelize
12562 vertical border check. (Bug#5357) (Bug#9618)
12564 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
12566 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
12567 errors in XSetWindowBorder (bug#9310).
12569 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
12571 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
12572 avoid crash when xmalloc overrun checking is enabled.
12574 2011-10-13 Eli Zaretskii <eliz@gnu.org>
12576 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
12577 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
12578 cursor motion with <left> and <right> arrow keys.
12580 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
12581 some callers set that themselves.
12583 2011-10-12 Eli Zaretskii <eliz@gnu.org>
12585 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
12586 display string and the previous row comes from the same string and
12587 is empty. (Bug#9739) (Bug#9738)
12589 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
12591 * doc.c (get_doc_string): Encode file name (bug#9735).
12593 2011-10-12 Eli Zaretskii <eliz@gnu.org>
12595 * bidi.c (bidi_level_of_next_char):
12596 * xdisp.c (get_visually_first_element): Remove old incorrect
12597 comments regarding the Unicode Line Separator character.
12599 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
12601 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
12603 * alloc.c (Fgc_status): Do not access beyond zombies array
12604 boundary if nzombies > MAX_ZOMBIES.
12605 * alloc.c (dump_zombies): Add missing format specifier.
12607 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
12609 * xdisp.c (set_cursor_from_row): Simplify conditionals,
12610 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
12612 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
12613 Some packages use them to denote characters with modifiers.
12615 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
12617 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
12618 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
12619 matching a pp-number. Rename parameter var to var1.
12621 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
12623 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
12625 2011-10-08 Glenn Morris <rgm@gnu.org>
12627 * callint.c (Fcall_interactively): Give a more explicit error for the
12628 'c' case with a non-character input. (Bug#8479)
12630 2011-10-08 Eli Zaretskii <eliz@gnu.org>
12632 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
12634 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
12635 lines that are hscrolled on the left.
12637 * dispnew.c (buffer_posn_from_coords): Account for a possible
12638 presence of header-line. (Bug#4426)
12640 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
12642 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
12643 Don't advertise functionality which we discourage or doesn't work.
12645 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
12647 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
12648 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
12649 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
12650 this makes Emacs dump core during garbage collection on rare
12651 occasions. sizeof is obviously inferior to offsetof here, so
12652 stick with offsetof.
12653 (GC_POINTER_ALIGNMENT): New macro.
12654 (mark_memory): Omit 3rd (offset) arg; caller changed.
12655 Don't assume EMACS_INT alignment is the same as pointer alignment.
12657 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
12659 * keyboard.c (read_key_sequence_remapped): New var.
12660 (read_key_sequence): Compute remapping in the right buffer.
12661 (command_loop_1): Use read_key_sequence's remapping directly.
12663 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
12665 * dired.c (file_name_completion): Don't expand file name.
12666 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
12667 before checking file name handler.
12669 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
12670 they've been requested explicitly (bug#9591).
12672 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
12674 * keymap.c (Fsingle_key_description): Use make_specified_string
12675 instead of build_string to build string from push_key_description.
12678 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
12680 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
12681 This fixes a Y2038 bug on 64-bit hosts.
12682 * buffer.c (reset_buffer):
12683 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
12684 (Fclear_buffer_auto_save_failure):
12685 Use 0, not -1, to represent an unset failure time, since time_t
12686 might not be signed.
12688 Remove dependency on glibc malloc internals.
12689 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12690 Move back here from lisp.h, but with their new implementations.
12691 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
12692 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
12693 * charset.c (charset_table_init): New static var.
12694 (syms_of_charset): Use it instead of xmalloc. This removes a
12695 dependency on glibc malloc internals. See Eli Zaretskii's comment in
12696 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
12697 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12698 Move back to alloc.c.
12699 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
12700 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
12702 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
12704 * nsterm.m (windowDidResize): Call x_set_window_size only when
12705 ns_in_resize is true. Otherwise set pixelwidth/height and
12706 call change_frame_size (Bug#9628).
12708 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
12710 Port --enable-checking=all to Fedora 14 x86-64.
12711 * charset.c (syms_of_charset): Also account for glibc malloc's
12712 internal overhead when calculating the initial malloc maximum.
12714 Port --enable-checking=all to Fedora 14 x86.
12715 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12717 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
12718 (overrun_check_realloc, overrun_check_free):
12719 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
12720 That way, xmalloc returns a properly-aligned pointer even if
12721 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
12722 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
12723 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
12724 into account when calculating the initial malloc maximum.
12725 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12726 Move here from alloc.c, so that charset.c can use it too.
12727 Properly align; the old code wasn't right for common 32-bit hosts
12728 when configured with --enable-checking=all.
12729 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
12730 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
12732 2011-09-29 Eli Zaretskii <eliz@gnu.org>
12734 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
12737 2011-09-28 Eli Zaretskii <eliz@gnu.org>
12739 * xdisp.c (compute_display_string_end): If there's no display
12740 string at CHARPOS, return -1.
12742 * bidi.c (bidi_fetch_char): When compute_display_string_end
12743 returns a negative value, treat the character as a normal
12744 character not covered by a display string. (Bug#9624)
12746 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
12748 * lread.c (Fread_from_string): Fix typo in docstring.
12750 2011-09-27 Eli Zaretskii <eliz@gnu.org>
12752 * xdisp.c (handle_invisible_prop): If invisible text ends on a
12753 newline, reseat the iterator instead of bidi-iterating there one
12754 character at a time. (Bug#9610)
12755 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
12756 TO_CHARPOS if the bidi iterator is at base embedding level.
12758 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
12760 * lread.c (readevalloop): Use correct code for NBSP.
12761 (read1): Likewise. (Bug#9608)
12763 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
12765 * dbusbind.c (Fdbus_register_signal): When service is not
12766 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
12768 2011-09-25 Glenn Morris <rgm@gnu.org>
12770 * buffer.c (truncate-lines): Doc fix.
12772 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
12774 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
12775 (Fset_window_next_buffers): Doc fix.
12777 2011-09-24 Glenn Morris <rgm@gnu.org>
12779 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
12781 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
12783 Fix minor problems found by static checking.
12784 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
12785 * indent.c (Fvertical_motion): Fix == vs = typo.
12787 2011-09-24 Eli Zaretskii <eliz@gnu.org>
12789 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
12790 Default value is now t. Doc fix.
12792 * indent.c (Fvertical_motion): Compute and apply the overshoot
12793 logic when moving up, not only when moving down. Fix the
12794 confusing name and values of the it_overshoot_expected variable;
12795 logic changes accordingly. (Bug#9254) (Bug#9549)
12797 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
12798 CHARPOS is covered by a display string which includes newlines.
12799 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
12800 is covered by a display string with embedded newlines.
12802 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
12804 * dbusbind.c (Fdbus_register_signal): Add match rule to
12805 Vdbus_registered_objects_table. (Bug#9581)
12806 (Fdbus_register_method, Vdbus_registered_objects_table):
12809 2011-09-24 Jim Meyering <meyering@redhat.com>
12811 do not ignore write error for any output size
12812 The previous change was incomplete.
12813 While it makes emacs --batch detect the vast majority of stdout
12814 write failures, errors were still ignored whenever the output size is
12815 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
12816 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
12817 && echo FAIL: ignored write error
12818 FAIL: ignored write error
12819 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
12820 && echo FAIL: ignored write error
12821 FAIL: ignored write error
12822 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
12824 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
12826 * emacs.c (Fkill_emacs): In noninteractive mode exit
12827 non-successfully if a write error occurred on stdout. (Bug#9574)
12829 2011-09-21 Eli Zaretskii <eliz@gnu.org>
12831 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
12834 * dispextern.h (struct it): Update the comment documenting what
12837 2011-09-20 Eli Zaretskii <eliz@gnu.org>
12839 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
12840 a display string, extend search for cursor position to end of row.
12841 (find_row_edges): If the row ends in a newline from a display
12842 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
12843 Handle the case of a display string with multiple newlines.
12844 (Fcurrent_bidi_paragraph_direction): Fix search for previous
12845 non-empty line. Fixes confusing cursor motion with arrow keys at
12846 the beginning of a line that starts with whitespace.
12848 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
12850 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
12853 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
12855 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
12856 boolean (Bug#9154).
12858 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12860 * xdisp.c (display_line): Record maximum and minimum buffer
12861 positions even if no glyphs were produced (e.g., by a zero-width
12862 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
12863 buffer positions that will be removed from the glyph row because
12865 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
12866 column is beyond frame width: don't subtract 1 "pixel" when
12867 computing width of the stretch.
12868 (reseat_at_next_visible_line_start): Undo the change made on
12869 2011-09-17 that saved paragraph information and restored it after
12870 the call to `reseat'. (Bug#9545)
12872 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12874 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
12875 and turn window cursor on if cleared (Bug#9415).
12877 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
12879 * search.c (boyer_moore): Take unibyte characters from pattern
12880 literally. (Bug#9458)
12882 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12884 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
12886 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
12888 Fix minor problem found by static checking.
12889 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
12890 initialized, to pacify gcc -Wuninitialized.
12892 * fileio.c: Report proper errno when syscall falls.
12893 (Finsert_file_contents): Save and restore errno,
12894 so that report_file_error outputs the correct diagnostic.
12895 (Fwrite_region) [CLASH_DETECTION]: Likewise.
12897 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12899 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
12901 2011-09-17 Eli Zaretskii <eliz@gnu.org>
12903 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
12904 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
12906 2011-09-17 Eli Zaretskii <eliz@gnu.org>
12908 * xdisp.c (reseat_at_next_visible_line_start): Keep information
12909 about the current paragraph and restore it after the call to reseat.
12911 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
12912 (bidi_find_paragraph_start): Search back for paragraph beginning
12913 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
12914 (bidi_move_to_visually_next): Only trigger paragraph-related
12915 computations when the last character is a newline or at EOB, not
12916 just any NEUTRAL_B. (Bug#9470)
12918 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
12919 truncated lines if point is covered by a display string. (Bug#9524)
12921 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
12923 * xselect.c: Relax test for outgoing X longs (Bug#9498).
12924 (cons_to_x_long): New function.
12925 (lisp_data_to_selection_data): Use it. Correct the test for
12926 short-versus-long data; it was negated. Break out of vector
12927 loop, for efficiency, when a long datum is discovered.
12929 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
12931 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
12933 2011-09-16 Eli Zaretskii <eliz@gnu.org>
12935 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
12936 GCC PR/17406) by declaring this function with external scope.
12938 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
12940 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).

12945 * editfns.c (Fformat): Correctly handle text properties on "%%".
12947 2011-09-15 Eli Zaretskii <eliz@gnu.org>
12949 * xterm.c (x_draw_composite_glyph_string_foreground):
12950 * w32term.c (x_draw_composite_glyph_string_foreground):
12951 * term.c (encode_terminal_code):
12952 * composite.c (composition_update_it, get_composition_id):
12953 * xdisp.c (get_next_display_element)
12954 (fill_composite_glyph_string): Add comments about special meaning
12955 of TAB characters in a composition.
12957 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
12959 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
12960 This occurs when processing a multibyte format.
12961 Problem reported by Wolfgang Jenker.

12965 * xdisp.c (try_cursor_movement): Only check for exact match if
12966 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
12968 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
12970 Remove unused external symbols.
12971 * dispextern.h (calc_pixel_width_or_height): Remove decl.
12972 * xdisp.c (calc_pixel_width_or_height): Now static.
12973 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
12974 * indent.c (check_display_width):
12975 * w32term.c: Fix comment to match code.
12976 * xterm.c, xterm.h (x_catching_errors): Remove.
12978 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
12980 * xselect.c: Use signed conversions more consistently (Bug#9498).
12981 (selection_data_to_lisp_data): Assume incoming selection data are
12982 signed integers, not unsigned. This is to be consistent with
12983 outgoing selection data, which was modified to use signed integers
12984 in as part of the fix to Bug#9196 in response to Jan D.'s comment
12985 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
12986 expects long, not unsigned long.
12988 2011-09-14 Eli Zaretskii <eliz@gnu.org>
12990 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
12991 computation of loop end. Reported by Johan Bockgård
12994 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
12996 * frame.c (Fother_visible_frames_p): Function deleted.
12998 2011-09-12 Eli Zaretskii <eliz@gnu.org>
13000 * indent.c (compute_motion): Process display vector front to back
13001 rather than the other way around. (Bug#2496)
13003 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
13005 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
13007 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
13009 * minibuf.c (Fread_from_minibuffer): Doc fix.
13011 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13013 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
13014 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
13016 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
13018 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
13019 value for non-existent files.
13021 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13023 * fileio.c (Finsert_file_contents): If the file cannot be opened,
13024 set its "size" to -1. This will set the modtime_size field of
13025 the corresponding buffer to -1, which is what
13026 verify-visited-file-modtime expects for files that do not exist.
13029 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
13031 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
13033 * lisp.h: ... from here. push_key_description is no longer
13034 defined in keyboard.c, so its declaration should not be in
13035 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
13036 logically belongs with push_key_description.
13038 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
13040 * buffer.h: Include <sys/types.h> instead of <time.h>.
13041 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
13042 Problem reported by Herbert J. Skuhra.
13044 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
13046 * xml.c (parse_region): Make the parsing work for
13047 non-comment-starting XML files again (bug#9144).
13049 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
13051 * image.c (gif_load): Fix calculation of bottom and right corner.
13054 2011-09-10 Eli Zaretskii <eliz@gnu.org>
13056 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
13057 redisplay in small windows.
13059 2011-09-09 Eli Zaretskii <eliz@gnu.org>
13061 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
13063 2011-09-08 Martin Rudalics <rudalics@gmx.at>
13065 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
13066 Operate on live windows only.
13068 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
13070 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
13072 2011-09-07 Eli Zaretskii <eliz@gnu.org>
13074 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
13075 only under bidi iteration.
13077 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
13079 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
13081 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13083 isnan: Fix porting problem to Solaris 10 with bundled gcc.
13084 Without this fix, the command to link temacs failed due to an
13085 undefined symbol __builtin_isnan. This is because
13086 /usr/include/iso/math_c99.h #defines isnan(x) to
13087 __builtin_isnan(x), but the bundled gcc, which identifies itself
13088 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
13090 * floatfns.c (isnan): #undef, and then #define to a clone of
13092 (Fisnan): Always define, since it's always available now.
13093 (syms_of_floatfns): Always define isnan at the Lisp level.
13095 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13097 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
13099 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13101 * fileio.c: Fix bugs with large file offsets (Bug#9428).
13102 The previous code assumed that file offsets (off_t values) fit in
13103 EMACS_INT variables, which is not true on typical 32-bit hosts.
13104 The code messed up by falsely reporting buffer overflow in cases
13105 such as (insert-file-contents "big" nil 1 2) into an empty buffer
13106 when "big" contains more than 2**29 bytes, even though this
13107 inserts just one byte and does not overflow the buffer.
13108 (Finsert_file_contents): Store file offsets as off_t
13109 values, not as EMACS_INT values. Check for overflow when
13110 converting between EMACS_INT and off_t. When checking for
13111 buffer overflow or for overlap, take the offsets into account.
13112 Don't use EMACS_INT for small values where int suffices.
13113 When checking for overlap, fix a typo: ZV was used where
13114 ZV_BYTE was intended.
13115 (Fwrite_region): Don't assume off_t fits into 'long'.
13116 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
13118 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
13120 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
13122 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13124 sprintf-related integer and memory overflow issues (Bug#9412).
13126 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
13127 (esprintf, exprintf, evxprintf): New functions.
13128 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
13129 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
13130 (modify_event_symbol): Do not assume that the length of
13131 name_alist_or_stem is safe to alloca and fits in int.
13132 (Fexecute_extended_command): Likewise for function name and binding.
13133 (Frecursion_depth): Wrap around reliably on integer overflow.
13134 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
13135 since some callers pass EMACS_INT values.
13136 (Fsingle_key_description): Don't crash if symbol name contains more
13137 than MAX_ALLOCA bytes.
13138 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
13139 (get_minibuffer): Arg is now EMACS_INT, not int.
13140 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
13141 (esprintf, exprintf, evxprintf): New decls.
13142 * window.h (command_loop_level, minibuf_level): Reflect API changes.
13144 * dbusbind.c (signature_cat): New function.
13145 (xd_signature, Fdbus_register_signal):
13146 Do not overrun buffer; instead, report string overflow.
13148 * dispnew.c (add_window_display_history): Don't overrun buffer.
13149 Truncate instead; this is OK since it's just a log.
13151 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
13152 even if the time zone offset is outlandishly large.
13153 Don't mishandle offset == INT_MIN.
13155 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
13156 when creating daemon; the previous buffer-overflow check was incorrect.
13158 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
13159 which has the guts of the old verror function.
13161 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
13162 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
13164 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
13165 (font_unparse_xlfd): Don't blindly alloca long strings.
13166 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
13167 fits in int, when using sprintf. Use single snprintf to count
13168 length of string rather than counting it via multiple sprintfs;
13169 that's simpler and more reliable.
13170 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
13171 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
13172 sprintf, in case result does not fit in int.
13174 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
13175 (fontset_from_font): Print it.
13177 * frame.c (tty_frame_count): Now printmax_t, not int.
13178 (make_terminal_frame, set_term_frame_name): Print it.
13179 (x_report_frame_params): In X, window IDs are unsigned long,
13180 not signed long, so print them as unsigned.
13181 (validate_x_resource_name): Check for implausibly long names,
13182 and don't assume name length fits in 'int'.
13183 (x_get_resource_string): Don't blindly alloca invocation name;
13184 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
13187 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
13188 (xg_check_special_colors, xg_set_geometry):
13189 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
13191 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
13192 Use esprintf, not sprintf, in case result does not fit in int.
13194 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13195 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
13196 it as a large positive number.
13197 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
13198 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13200 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
13201 in case result does not fit in int.
13203 * print.c (float_to_string): Detect width overflow more reliably.
13204 (print_object): Make sprintf buffer a bit bigger, to avoid potential
13205 buffer overrun. Don't assume list length fits in 'int'. Treat
13206 print length of 0 as 0, not as infinity; to be consistent with other
13207 uses of print length in this function. Don't overflow print length
13208 index. Don't assume hash table size fits in 'long', or that
13209 vectorlike size fits in 'unsigned long'.
13211 * process.c (make_process): Use printmax_t, not int, to format
13212 process-name gensyms.
13214 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
13216 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
13217 to avoid potential buffer overrun.
13219 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
13220 if X resource line is longer than 512 bytes.
13222 * xfns.c (x_window): Make sprintf buffer a bit bigger
13223 to avoid potential buffer overrun.
13225 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
13227 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
13229 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13231 Integer overflow fixes for scrolling, etc.
13232 Without these, Emacs silently mishandles large integers sometimes.
13233 For example, "C-u 4294967297 M-x recenter" was treated as if
13234 it were "C-u 1 M-x recenter" on a typical 64-bit host.
13236 * xdisp.c (try_window_id): Check Emacs fixnum range before
13237 converting to 'int'.
13239 * window.c (window_scroll_line_based, Frecenter):
13240 Check that an Emacs fixnum is in range before assigning it to 'int'.
13241 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
13242 values converted from Emacs fixnums.
13243 (Frecenter): Don't wrap around a line count if it is out of 'int'
13244 range; instead, treat it as an extreme value.
13245 (Fset_window_configuration, compare_window_configurations):
13246 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
13248 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
13249 that can exceed INT_MAX. Check that EMACS_INT value is in range
13250 before assigning it to the (possibly-narrower) index.
13251 (match_limit): Don't assume that a fixnum can fit in 'int'.
13253 * print.c (print_object): Use ptrdiff_t, not int, for index that can
13256 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
13257 (Fvertical_motion): Don't wrap around LINES values that don't fit
13258 in 'int'. Instead, treat them as extreme values. This is good
13259 enough for windows, which can't have more than INT_MAX lines anyway.
13261 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
13263 * Require libxml/parser.h to avoid compilation warning.
13265 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
13267 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
13268 since this reportedly can destroy thread storage.
13270 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
13272 * syntax.c (find_defun_start): Update all cache variables if
13273 exiting early (Bug#9401).
13275 2011-08-30 Eli Zaretskii <eliz@gnu.org>
13277 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
13279 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
13280 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
13281 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
13283 * term.c (tty_append_glyph): New function.
13284 (produce_stretch_glyph): Static function and its prototype deleted.
13286 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
13289 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
13291 * image.c (parse_image_spec): Check for nonnegative, not for positive,
13292 when checking :margin (Bug#9390).
13293 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
13294 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
13295 so that the name doesn't mislead. All uses changed.
13297 2011-08-28 Johan Bockgård <bojohan@gnu.org>
13299 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
13302 2011-08-27 Eli Zaretskii <eliz@gnu.org>
13304 * xdisp.c (move_it_to): Don't bail out early when reaching
13305 position beyond to_charpos, if we are scanning backwards.
13306 (move_it_vertically_backward): When DY == 0, make sure we get to
13307 the first character in the line after the newline.
13309 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
13311 * ccl.c: Improve and simplify overflow checking (Bug#9196).
13312 (ccl_driver): Do not generate an out-of-range pointer.
13313 (Fccl_execute_on_string): Remove unnecessary check for
13314 integer overflow, noted by Stefan Monnier in
13315 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
13316 Remove a FIXME that didn't need fixing.
13317 Simplify the newly-introduced buffer reallocation code.
13319 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
13321 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
13323 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
13325 Integer and memory overflow issues (Bug#9196).
13327 * doc.c (get_doc_string): Rework so that
13328 get_doc_string_buffer_size is the actual buffer size, rather than
13329 being 1 less than the actual buffer size; this makes xpalloc more
13332 * image.c (x_allocate_bitmap_record, cache_image):
13333 * xselect.c (Fx_register_dnd_atom):
13334 Simplify previous changes by using xpalloc.
13336 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
13337 since either will do and ptrdiff_t is convenient with xpalloc.
13339 * charset.c (charset_table_size)
13340 (struct charset_sort_data.priority): Now ptrdiff_t.
13341 (charset_compare): Don't overflow if priorities differ greatly.
13342 (Fsort_charsets): Don't assume list length fits in int.
13343 Check for size-calculation overflow when allocating sort data.
13344 (syms_of_charset): Allocate an initial charset table that is
13345 just under 64 KiB, to avoid problems with glibc malloc and mmap.
13347 * cmds.c (internal_self_insert): Check for size-calculation overflow.
13349 * composite.h (struct composition.glyph_len): Now int, not unsigned.
13350 The actual value is always <= INT_MAX, and leaving it unsigned made
13351 overflow checking harder.
13353 * dispextern.h (struct glyph_matrix.rows_allocated)
13354 (struct face_cache.size): Now ptrdiff_t, for convenience in use
13355 with xpalloc. The values are still always <= INT_MAX.
13357 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
13359 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
13360 (SAFE_NALLOCA): New macro.
13362 * region-cache.c (struct boundary.pos, find_cache_boundary)
13363 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
13364 (set_cache_region, invalidate_region_cache)
13365 (revalidate_region_cache, know_region_cache, region_cache_forward)
13366 (region_cache_backward, pp_cache):
13367 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
13368 so that ptrdiff_t * can be passed to xpalloc.
13369 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
13370 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
13371 (pp_cache): Don't assume cache_len fits in int.
13372 * region-cache.h: Adjust extern decls to match.
13374 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
13375 EMACS_INT, since either will do, for xpalloc.
13377 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
13378 (xnmalloc, xnrealloc, xpalloc): New functions.
13380 * bidi.c (bidi_shelve_header_size): New constant.
13381 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
13382 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
13384 * bidi.c (bidi_cache_shrink):
13385 * buffer.c (overlays_at, overlays_in, record_overlay_string)
13387 Don't update size of array until after memory allocation succeeds,
13388 because xmalloc/xrealloc may not return.
13389 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
13390 now that we have proper integer overflow checking.
13391 (record_overlay_string, overlay_strings): Catch overflows when
13392 calculating size of overlay_str_buf.
13394 * callproc.c (Fcall_process): Check for size overflow when
13395 calculating size of args2.
13396 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
13397 Normally we prefer signed values, but sticking with ptrdiff_t would
13398 require adding more-complicated checks.
13400 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
13401 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
13402 Redo buffer-overflow calculations to avoid integer overflow.
13403 Add a FIXME comment where memory seems to be over-allocated.
13405 * character.c (Fstring): Check for size-calculation overflow.
13407 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
13408 unnecessary integer overflow. Check for size overflow.
13409 (encode_coding_object): Don't update size until xmalloc succeeds.
13411 * composite.c (get_composition_id): Check for overflow in glyph
13412 length calculations.
13414 Integer and memory overflow fixes for display code.
13415 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
13416 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
13417 (scrolling_window): Check for overflow in size calculations.
13418 (line_draw_cost, realloc_glyph_pool, add_row_entry):

13441 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
13443 * emacs.c (main): Do not reallocate argv, since there is a null at
13444 the end that can be overwritten, and this way there's no need to
13445 worry about size-calculation overflow.

13575 (X_LONG_MIN): New macros.
13576 Use them to make the following changes clearer.
13577 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.

13579 future maintainers not to raise the value too much later.
13580 (SELECTION_QUANTUM): Remove, replacing with ...
13581 (selection_quantum): ... new function, which avoids overflow.
13583 (struct selection_data.size): Now ptrdiff_t, not int, to avoid

13601 Don't store size until memory allocation succeeds.
13602 (x_get_window_property): Plug memory leak on memory exhaustion.
13603 Don't double-block input; malloc is safe here. Don't assume 2**34
13604 - 4 fits in unsigned long. Add an xassert to check
13605 XGetWindowProperty overflow. Be more careful about overflow
13606 calculations, and distinguish size from memory overflow better.

13613 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
13614 result parameters unless successful. Rely on cons_to_unsigned
13615 to report problems with elements; the old code wasn't right anyway.

13650 * lisp.h (hash_lookup, hash_put):
13651 * minibuf.c (Ftest_completion):
13652 Use ptrdiff_t for hash table indexes, not int (which is too
13653 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on

13688 exceed limits imposed by XClientMessageEvent, as well as the usual
13689 ptrdiff_t and size_t limits.

13692 (make_lispy_movement): Use same integer type in forward decl
13693 that is used in the definition.

13695 Change bufsize argument back to int, undoing my 2011-03-30 change.
13696 We prefer signed types, and int is wide enough here.
13697 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
13698 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
13699 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
13700 length, not size_t. Use ptrdiff_t for index, not int.
13701 (keyremap_step, read_key_sequence): Redo bufsize check to avoid

13730 Prefer int to unsigned where either will do.
13731 (tiff_handler): New function, combining the cores of the
13732 old tiff_error_handler and tiff_warning_handler.

13734 stack buffer overflows. It uses only the features of vsnprintf
13735 that are common to both POSIX and native Microsoft.
13736 (tiff_error_handler, tiff_warning_handler): Use it.
13737 (tiff_load, gif_load, imagemagick_load_image):
13738 Don't assume :index value fits in 'int'.

13784 positioning on the newline at EOL of R2L text within L2R
13785 paragraph, and vice versa.
13786 (try_cursor_movement): Check continued rows, in addition to
13787 continuation rows. Fixes unwarranted scroll when point enters a
13788 continued line of R2L text within an L2R paragraph, or vice versa.
13789 (cursor_row_p): Consider the case of point being equal to
13790 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving

13819 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
13820 instead of CHAR_TO_BYTE. Fixes a crash when a completion
13821 candidate is selected by the mouse, and that candidate has a
13822 composed character under the mouse.
13824 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
13825 coordinates reported by pos-visible-in-window-p for a composed

13840 * image.c (gif_load): Don't assume that each subimage has the same
13841 dimensions as the base image. Handle disposal method that is
13842 "undefined" by the gif spec (Bug#9335).

13849 2011-08-19 Eli Zaretskii <eliz@gnu.org>
13851 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
13852 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
13853 from an Org mode buffer to a Speedbar frame.
13855 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
13856 a composition, take its buffer position from IT->cmp_it.charpos.
13857 Fixes cursor positioning at the beginning of a line that begins
13858 with a composed character.
13860 2011-08-18 Eli Zaretskii <eliz@gnu.org>
13862 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
13863 character bidirectional type, use STRONG_L instead. Fixes crashes
13864 in a buffer produced by `describe-categories'.
13866 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
13867 members before the level stack, so they would be saved and
13868 restored when copying iterator state. Fixes incorrect reordering
13869 around TABs covered by display properties.
13871 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
13873 * process.c (Fnetwork_interface_list): Correctly determine buffer size.
13875 2011-08-17 Chong Yidong <cyd@stupidchicken.com>
13877 * eval.c (internal_condition_case, internal_condition_case_1)
13878 (internal_condition_case_2, internal_condition_case_n):
13879 Remove unnecessary aborts (Bug#9081).
13881 2011-08-17 Eli Zaretskii <eliz@gnu.org>
13883 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
13884 has no `load' handler, try opening the file locally. (Bug#9311)
13886 2011-08-16 Ken Brown <kbrown@cornell.edu>
13888 * gmalloc.c: Expand comment.
13890 2011-08-16 Eli Zaretskii <eliz@gnu.org>
13892 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
13893 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
13895 2011-08-16 Ken Brown <kbrown@cornell.edu>
13897 Fix memory allocation problems in Cygwin build (Bug#9273).

13904 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
13906 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
13907 in the static heap.
13908 [CYGWIN] (special_realloc): New function.
13909 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
13910 requests to realloc storage in the static heap.

13925 * chartab.c: Improve commentary for the uniprop_table API.
13927 * bidi.c (bidi_paragraph_init): Support zero value of
13928 bidi_ignore_explicit_marks_for_paragraph_level.
13929 (bidi_initialize): Use uniprop_table instead of including
13930 biditype.h and bidimirror.h.
13932 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
13933 coordinates of the iterator when restoring from ppos_it.
13936 2011-08-14 Kenichi Handa <handa@m17n.org>

13939 after the pid of the process is set to -1 (Bug#8162).
13941 2011-08-14 Eli Zaretskii <eliz@gnu.org>
13943 * xdisp.c (move_it_in_display_line_to): Don't invoke
13944 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
13945 ppos_it. Fixes vertical cursor motion when line beginning is
13946 covered by an image. (Bug#9296)
13948 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
13950 * nsterm.h (ns_run_ascript): Declare.
13951 (NSAPP_DATA2_RUNASSCRIPT): Define.
13953 * nsfns.m (as_script, as_result, as_status): New static variables.
13954 (ns_run_ascript): New function.
13955 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
13956 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
13957 the event loop. Get status from as_status (Bug#7276).
13959 * nsterm.m (sendEvent): If event is NSApplicationDefined and
13960 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
13961 the event loop (Bug#7276).
13963 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
13965 * gnutls.c (QCgnutls_bootprop_priority)
13966 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
13967 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
13968 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
13969 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
13970 (QCgnutls_bootprop_verify_hostname_error)
13971 (QCgnutls_bootprop_callbacks_verify): Rename from
13972 Qgnutls_bootprop_..., all uses changed.
13974 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
13977 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
13979 * xfaces.c (Qframe_set_background_mode): Now static.

13984 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
13986 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
13987 (Fnetwork_interface_list): Allocate in increments of bytes instead
13988 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
13989 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
13991 (struct ifflag_def): notrailers is smart on OSX.
13992 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
13993 Get hardware address with getifaddrs if available.
13995 2011-08-12 Eli Zaretskii <eliz@gnu.org>
13997 * xdisp.c (iterate_out_of_display_property): xassert that
13998 IT->position is set to within IT->object's boundaries. Break from
13999 the loop as soon as EOB is reached; avoids infloops in redisplay
14000 when IT->position is set up wrongly due to some bug.
14001 Set IT->current to match the bidi iterator unconditionally.
14002 (push_display_prop): Allow GET_FROM_STRING as IT->method on
14003 entry. Force push_it to save on the stack the current
14004 buffer/string position, to be restored by pop_it. Fix flags in
14005 the iterator structure wrt the object coming from a display
14006 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
14007 properties. (Bug#9284)
14009 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
14011 * fontset.c (fontset_get_font_group): Add proper type checks.
14014 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>

14017 and LC_VERSION_MIN_MACOSX.
14018 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
14019 (dump_it) [LC_FUNCTION_STARTS]: Use it.
14021 2011-08-08 Eli Zaretskii <eliz@gnu.org>

14024 no-display-properties-and-no-overlays under bidi display.
14025 Set disp_pos in the bidi iterator to avoid searches for display
14026 properties and overlays.
14028 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
14030 * editfns.c (Fset_time_zone_rule): Document relationship with the

14034 the font entity extracted from the cache (Bug#8109).
14036 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
14038 * composite.c (autocmp_chars): Don't reset point. That is done by
14039 restore_point_unwind (Bug#5984).
14041 2011-08-07 Juri Linkov <juri@jurta.org>
14043 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
14044 to show the arg `TIME' instead of `TIMEVAL'.
14046 2011-08-06 Eli Zaretskii <eliz@gnu.org>
14048 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
14049 display property strides EOL and includes a newline, as in
14050 longlines-mode. (Bug#9254)
14051 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
14052 word-wrap under bidirectional display. (Bug#9224)
14054 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
14055 is non-zero, even if the data buffer is NULL. Fixes a crash in
14056 vertical-motion with longlines-mode. (Bug#9254)
14058 2011-08-05 Eli Zaretskii <eliz@gnu.org>
14060 * bidi.c <bidi_cache_total_alloc>: Now static.
14061 (bidi_initialize): Initialize bidi_cache_total_alloc.
14063 * xdisp.c (display_line): Release buffer allocated for shelved bidi
14066 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
14067 amount allocated this far in `bidi_cache_total_alloc'.
14068 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
14069 non-zero, only free the data buffer without restoring the cache
14070 contents. All callers changed.
14072 * dispextern.h (bidi_unshelve_cache): Update prototype.
14074 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
14075 (move_it_in_display_line, move_it_to)
14076 (move_it_vertically_backward, move_it_by_lines): Replace the call
14077 to xfree to an equivalent call to bidi_unshelve_cache.
14078 (move_it_in_display_line_to): Fix logic of returning
14079 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
14081 2011-08-05 Eli Zaretskii <eliz@gnu.org>
14083 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
14084 came from a string character with a `cursor' property. (Bug#9229)
14086 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
14088 * Makefile.in (LIB_PTHREAD): New variable.
14089 (LIBES): Add LIB_PTHREAD (Bug#9216).
14091 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
14092 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
14094 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
14096 * regex.c (re_iswctype): Remove some redundant boolean conversions.
14098 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
14100 * xterm.c (x_find_topmost_parent): New function.
14101 (x_set_frame_alpha): Find topmost parent window with
14102 x_find_topmost_parent and set the property there also (bug#9181).
14103 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
14105 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
14107 * callproc.c (Fcall_process): Avoid vfork clobbering
14108 the local vars buffer, coding_systems, current_dir.
14110 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
14112 * keymap.c (Fmake_composed_keymap): Move to subr.el.
14114 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
14116 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
14117 so that it is not optimized away.
14119 * xdisp.c (compute_display_string_pos): Remove unused local.
14121 2011-08-02 Eli Zaretskii <eliz@gnu.org>
14123 Fix slow cursor motion and scrolling in large buffers with
14124 selective display, like Org Mode buffers. (Bug#9218)
14126 * dispextern.h (struct bidi_it): New member disp_prop_p.
14128 * xdisp.c: Remove one-slot cache of display string positions.
14129 (compute_display_string_pos): Accept an additional argument
14130 DISP_PROP_P; callers changed. Scan at most 5K characters forward
14131 for a display string or property. If found, set DISP_PROP_P
14134 * bidi.c (bidi_fetch_char): Accept an additional argument
14135 DISP_PROP_P, and pass it to compute_display_string_pos.
14136 Only handle text covered by a display string if DISP_PROP_P is returned
14137 non-zero. All callers of bidi_fetch_char changed.
14139 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
14141 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
14143 2010-12-03 Don March <don@ohspite.net>
14145 * keymap.c (Fdefine_key): Fix non-prefix key error message when
14146 last character M-[char] is translated to ESC [char] (bug#7541).
14148 2011-08-02 Kenichi Handa <handa@m17n.org>
14150 * lisp.h (uniprop_table): Extern it.
14152 * chartab.c (uniprop_table): Make it non-static.
14154 2011-08-01 Eli Zaretskii <eliz@gnu.org>
14156 * xdisp.c (forward_to_next_line_start): Accept additional argument
14157 BIDI_IT_PREV, and store into it the state of the bidi iterator had
14159 (reseat_at_next_visible_line_start): Use the bidi iterator state
14160 returned by forward_to_next_line_start to restore the state of
14161 it->bidi_it after backing up to previous newline. (Bug#9212)
14163 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
14165 * regex.c (re_comp): Protoize.
14166 (re_exec): Fix return type.
14167 (regexec): Fix type of `ret'. (Bug#9203)
14169 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14171 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
14172 This is needed if max-image-size is a floating-point number.
14174 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
14176 * print.c (print_object): Print empty symbol as ##.
14178 * lread.c (read1): Read ## as empty symbol.
14180 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
14182 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
14183 setting frame foreground color (Bug#9175).
14184 (x_set_background_color): Likewise.
14186 * nsmenu.m (-setText): Size tooltip dimensions precisely to
14187 contents (Bug#9176).
14188 (EmacsTooltip -init): Remove bezels and add shadows to
14191 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
14192 or scroll bar (Bug#8470).
14194 * nsfont.m (nsfont_open): Remove assignment to voffset and
14195 unnecessary vars hshink, expand, hd, full_height, min_height.
14196 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
14198 * nsterm.h (nsfont_info): Remove voffset field.
14200 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
14202 Implement strike-through and overline on NextStep (Bug#8863).
14204 * nsfont.m (nsfont_open): Use underline position provided by font,
14205 instead of hard-coded value of 2.
14206 (nsfont_draw): Call ns_draw_text_decoration instead.
14208 * nsterm.h: Add declaration for ns_draw_text_decoration.
14210 * nsterm.m (ns_draw_text_decoration): New function for drawing
14211 underline, overline, and strike-through.
14212 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
14213 ns_draw_text_decoration. Change treatment of cursor drawing to
14214 accommodate underlining, etc.
14216 2011-07-28 Eli Zaretskii <eliz@gnu.org>
14218 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
14221 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14223 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
14224 Without this fix, if a signal arrives just after memory fills up,
14225 'malloc' might be invoked reentrantly.
14227 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
14228 In other words, assume that every image size is allowed, on non-X
14229 hosts. This assumption is probably wrong, but it lets Emacs compile.
14231 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
14233 * regex.c (re_iswctype): Convert return values to boolean.
14235 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
14237 * xdisp.c (compute_display_string_pos): Don't use cached display
14238 string position if the buffer had its restriction changed.
14241 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14243 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
14245 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14247 Integer signedness and overflow and related fixes. (Bug#9079)
14249 * bidi.c: Integer size and overflow fixes.
14250 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
14251 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
14252 (bidi_cache_find_level_change, bidi_cache_ensure_space)
14253 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
14254 (bidi_find_other_level_edge):
14255 Use ptrdiff_t instead of EMACS_INT where either will do.
14256 This works better on 32-bit hosts configured --with-wide-int.
14257 (bidi_cache_ensure_space): Check for size-calculation overflow.
14258 Use % rather than repeated addition, for better worst-case speed.
14259 Don't set bidi_cache_size until after xrealloc returns, because it
14261 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
14262 (bidi_cache_ensure_space): Also check that the bidi cache size
14263 does not exceed that of the largest Lisp string or buffer. See Eli
14264 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
14266 * alloc.c (__malloc_size_t): Remove.
14267 All uses replaced by size_t. See Andreas Schwab's note
14268 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
14270 * image.c: Improve checking for integer overflow.
14271 (check_image_size): Assume that f is nonnull, since
14272 it is always nonnull in practice. This is one less thing to
14273 worry about when checking for integer overflow later.
14274 (x_check_image_size): New function, which checks for integer
14275 overflow issues inside X.
14276 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
14277 This removes the need for a memory_full check.
14278 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
14279 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
14280 (xbm_read_bitmap_data): Change locals back to 'int', since
14281 their values must fit in 'int'.
14282 (xpm_load_image, png_load, tiff_load):
14283 Invoke x_create_x_image_and_pixmap earlier,
14284 to avoid much needless work if the image is too large.
14285 (tiff_load): Treat overly large images as if
14286 x_create_x_image_and_pixmap failed, not as malloc failures.
14287 (gs_load): Use x_check_image_size.
14289 * gtkutil.c: Omit integer casts.
14290 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
14291 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
14293 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
14295 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
14296 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
14297 would wrongly return t on a 64-bit host.
14299 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
14300 The plain *_OVERFLOW macros run afoul of GCC bug 49705
14301 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
14302 and therefore cause GCC to emit a bogus diagnostic in some cases.
14304 * image.c: Integer signedness and overflow and related fixes.
14305 This is not an exhaustive set of fixes, but it's time to
14306 record what I've got.
14307 (lookup_pixel_color, check_image_size): Remove redundant decls.
14308 (check_image_size): Don't assume that arbitrary EMACS_INT values
14309 fit in 'int', or that arbitrary 'double' values fit in 'int'.
14310 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
14311 (tiff_load, imagemagick_load_image):
14312 Check for overflow in size calculations.
14313 (x_create_x_image_and_pixmap): Remove unnecessary test for
14314 xmalloc returning NULL; that can't happen.
14315 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
14316 (xpm_color_bucket): Use better integer hashing function.
14317 (xpm_cache_color): Don't possibly over-allocate memory.
14318 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
14319 (gif_memory_source):
14320 Use ptrdiff_t, not int or size_t, to record sizes.
14321 (png_load): Don't assume values greater than 2**31 fit in 'int'.
14322 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
14323 either works, as we prefer signed integers.
14324 (tiff_read_from_memory, tiff_write_from_memory):
14325 Return tsize_t, not size_t, since that's what the TIFF API wants.
14326 (tiff_read_from_memory): Don't fail simply because the read would
14327 go past EOF; instead, return a short read.
14328 (tiff_load): Omit no-longer-needed casts.
14329 (Fimagemagick_types): Don't assume size fits into 'int'.
14331 Improve hashing quality when configured --with-wide-int.
14332 * fns.c (hash_string): New function, taken from sxhash_string.
14333 Do not discard information about ASCII character case; this
14334 discarding is no longer needed.
14335 (sxhash-string): Use it. Change sig to match it. Caller changed.
14336 * lisp.h: Declare it.
14337 * lread.c (hash_string): Remove, since we now use fns.c's version.
14338 The fns.c version returns a wider integer if --with-wide-int is
14339 specified, so this should help the quality of the hashing a bit.
14341 * emacs.c: Integer overflow minor fix.
14342 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
14343 Define only if GNU_LINUX.
14344 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
14346 * dispnew.c: Integer signedness and overflow fixes.
14347 Remove unnecessary forward decls, that were a maintenance hassle.
14348 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
14350 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
14351 (scrolling_window): Use ptrdiff_t, not int, for byte count.
14352 (prepare_desired_row, line_draw_cost):
14353 Use int, not unsigned, where either works.
14354 (save_current_matrix, restore_current_matrix):
14355 Use ptrdiff_t, not size_t, where either works.
14356 (init_display): Check for overflow more accurately, and without
14357 relying on undefined behavior.
14359 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
14360 Remove, replacing with the new symbols in lisp.h. All uses changed.
14361 * fileio.c (make_temp_name):
14362 * filelock.c (lock_file_1, lock_file):
14363 * xdisp.c (message_dolog):
14364 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
14365 Use pMd etc. instead.
14366 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
14367 replacing the pWIDE etc. symbols removed from editfns.c.
14369 * keyboard.h (num_input_events): Now uintmax_t.
14370 This is (very slightly) less likely to mess up due to wraparound.
14373 * buffer.c: Integer signedness fixes.
14374 (alloc_buffer_text, enlarge_buffer_text):
14375 Use ptrdiff_t rather than size_t when either will do, as we prefer
14378 * alloc.c: Integer signedness and overflow fixes.
14379 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
14380 (__malloc_size_t): Default to size_t, not to int.
14381 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
14382 (Fgarbage_collect, mark_object_loop_halt, mark_object):
14383 Prefer ptrdiff_t to size_t when either would do, as we prefer
14385 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
14386 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
14387 Now const. Initialize with values that are in range even if char
14389 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
14390 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
14391 These functions do the right thing with sizes > 2**32.
14392 (check_depth): Now ptrdiff_t, not int.
14393 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
14394 Adjust to new way of storing sizes. Check for size overflow bugs
14396 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
14397 slightly wrong anyway, as it missed one instance of
14398 XMALLOC_OVERRUN_CHECK_OVERHEAD.
14399 (refill_memory_reserve): Omit needless cast to size_t.
14400 (mark_object_loop_halt): Mark as externally visible.
14402 * xselect.c: Integer signedness and overflow fixes.
14403 (Fx_register_dnd_atom, x_handle_dnd_message):
14404 Use ptrdiff_t, not size_t, since we prefer signed.
14405 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
14406 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
14407 x_dnd_atoms_size and x_dnd_atoms_length.
14409 * doprnt.c: Prefer signed to unsigned when either works.
14411 * doprnt.c (doprnt):
14413 * xdisp.c (vmessage):
14414 Use ptrdiff_t, not size_t, when using or implementing doprnt,
14415 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
14416 prefer signed arithmetic to avoid comparison confusion.
14417 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
14418 but is a bit tricky.
14420 Assume freestanding C89 headers, string.h, stdlib.h.
14421 * data.c, doprnt.c, floatfns.c, print.c:
14422 Include float.h unconditionally.
14423 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
14424 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
14425 * regex.c: Likewise for stddef.h, string.h.
14426 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
14427 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
14428 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
14429 (STDC_HEADERS): Remove obsolete defines.
14430 * sysdep.c: Include limits.h unconditionally.
14432 Assume support for memcmp, memcpy, memmove, memset.
14433 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
14434 * regex.c (memcmp, memcpy):
14435 Remove; we assume C89 now.
14437 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
14438 (__malloc_safe_bcopy): Remove; no longer needed.
14440 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
14441 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
14442 well either way, and we prefer signed to unsigned.
14444 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
14446 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
14447 closes the connection while we're reading (bug#9182).
14449 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
14451 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
14452 are specified (Bug#9168).
14454 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
14456 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
14457 Found by GCC static checking and --with-wide-int on a 32-bit host.
14459 2011-07-25 Eli Zaretskii <eliz@gnu.org>
14461 * xdisp.c (compute_display_string_pos): Fix logic of caching
14462 previous display string position. Initialize cached_prev_pos to
14463 -1. Fixes slow-down at the beginning of a buffer.
14465 2011-07-24 Eli Zaretskii <eliz@gnu.org>
14467 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
14468 for attrs[LFACE_FONTSET_INDEX].
14470 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
14472 * xml.c (parse_region): Remove unused local
14473 that was recently introduced.
14475 2011-07-23 Eli Zaretskii <eliz@gnu.org>
14477 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
14478 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
14480 * xdisp.c (move_it_in_display_line_to): Record the best matching
14481 position for TO_CHARPOS while scanning the line, and restore it on
14482 exit if none of the characters scanned was an exact match.
14483 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
14484 when exact match is impossible due to invisible text, and the
14485 lines are truncated.
14487 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
14489 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
14492 2011-07-22 Eli Zaretskii <eliz@gnu.org>
14494 Fix a significant slow-down of cursor motion with C-n, C-p,
14495 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
14496 auto-repeat under bidi redisplay in fontified buffers.
14497 * xdisp.c (compute_stop_pos_backwards): New function.
14498 (next_element_from_buffer): Call compute_stop_pos_backwards to
14499 find a suitable prev_stop when we find ourselves before
14501 (reseat): Don't look for prev_stop, as that could mean a very long
14503 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
14504 <cached_disp_overlay_modiff>: Cache for last found display string
14506 (compute_display_string_pos): Return the cached position if asked
14507 about the same buffer in the same area of character positions, and
14508 the buffer wasn't changed since the time the display string
14509 position was cached.
14511 2011-07-22 Eli Zaretskii <eliz@gnu.org>
14513 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
14514 is an integer, which is important for empty lines. (Bug#9149)
14516 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
14518 * frame.c (Fmodify_frame_parameters): In tty case, update the
14519 default face if necessary (Bug#4238).
14521 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
14523 * editfns.c (Fstring_to_char): No need to explain what a character
14524 is in the docstring (Bug#6576).
14526 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
14528 * xml.c (parse_region): Make sure we always return a tree.
14530 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
14532 * xml.c (parse_region): If a document contains only comments,
14535 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
14537 * xml.c (make_dom): Return comments, too.
14539 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
14542 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
14543 and the surrounding thread.
14544 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
14545 rather than fgets, and retry after EINTR. Otherwise, 'emacs
14546 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
14548 * s/openbsd.h (BROKEN_SIGIO): Define.
14549 * unexelf.c (unexec) [__OpenBSD__]:
14550 Don't update the .mdebug section of the Alpha COFF symbol table.
14552 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14554 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
14557 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
14559 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
14560 This fixes some race conditions on the permissions of any newly
14563 * alloc.c (valid_pointer_p): Use pipe, not open.
14564 This fixes some permissions issues when debugging.
14566 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
14567 If fchown fails to set both uid and gid, try to set just gid,
14568 as that is sometimes allowed. Adjust the file's mode to eliminate
14569 setuid or setgid bits that are inappropriate if fchown fails.
14571 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
14573 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
14574 to compare Lisp_Objects.
14575 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
14576 global_gnutls_log_level, don't mistake it for a Lisp_Object.
14577 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
14579 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
14581 * lread.c (read_integer): Unread even EOF character.
14582 (read1): Likewise. Properly record start position of symbol.
14584 * lread.c (read1): Read `#:' as empty uninterned symbol if no
14585 symbol character follows.
14587 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
14589 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
14590 This works around a problem with the previous change to Fcopy_file.
14591 Recent glibc declares fchown with __attribute__((warn_unused_result)),
14592 and without this change, GCC might complain about discarding
14593 fchown's return value.
14595 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
14597 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
14599 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
14601 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
14603 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
14605 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
14606 it's used from the C level.
14608 * process.c: Use the same condition for POLL_FOR_INPUT in both
14609 keyboard.c and process.c (bug#1858).
14611 2011-07-09 Lawrence Mitchell <wence@gmx.li>
14613 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
14614 (Fgnutls_boot): Use it.
14616 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
14618 * doc.c (Fsubstitute_command_keys): Revert last change.
14620 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
14622 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
14623 quotes the next character, and doesn't affect other longer
14624 sequences (bug#8935).
14626 * lread.c (syms_of_lread): Clarify that is isn't only
14627 `eval-buffer' and `eval-defun' that's affected by
14628 `lexical-binding' (bug#8460).
14630 2011-07-15 Eli Zaretskii <eliz@gnu.org>
14632 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
14633 bidi redisplay when a line includes both an image and is truncated.
14635 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
14637 Fix minor problems found by static checking.
14638 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
14639 (elsz): Now a signed constant, not a size_t var. We prefer signed
14640 types to unsigned, to avoid integer comparison confusion. Without
14641 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
14642 "cannot optimize loop, the loop counter may overflow", a symptom
14644 * indent.c (Fvertical_motion): Mark locals as initialized.
14645 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
14647 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
14649 * search.c (Fre_search_backward): Mention `case-fold-search' in
14650 all the re_search_* functions (bug#8138).
14652 * keyboard.c (Fopen_dribble_file): Document when the file is
14655 2011-07-14 Eli Zaretskii <eliz@gnu.org>
14657 * bidi.c (bidi_dump_cached_states): Fix format of displaying
14660 Support bidi reordering of display and overlay strings.

14662 (compute_display_string_end): Accept additional argument STRING.
14663 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
14664 (reseat_to_string): Initialize bidi_it->string.s and
14665 bidi_it->string.schars.
14666 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
14667 NULL (avoids a crash in bidi_paragraph_init).
14668 Initialize itb.string.lstring.
14669 (init_iterator): Call bidi_init_it only of a valid
14670 buffer position was specified. Initialize paragraph_embedding to
14672 (reseat_to_string): Initialize the bidi iterator.
14673 (display_string): If we need to ignore text properties of
14674 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
14675 original value of -1 will not work with bidi.)
14676 (compute_display_string_pos): First arg is now struct
14677 `text_pos *'; all callers changed. Support display properties on
14679 (compute_display_string_end): Support display properties on Lisp
14681 (init_iterator, reseat_1, reseat_to_string): Initialize the
14682 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
14683 when iterating on a string not from display properties).
14684 (compute_display_string_pos, compute_display_string_end):
14685 Fix calculation of the object to scan. Fixes an error when using
14687 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
14688 base_level_stop; instead, set base_level_stop to BEGV.
14689 Fixes crashes in vertical-motion.
14690 (next_element_from_buffer): Improve commentary for when
14691 the iterator is before prev_stop.
14692 (init_iterator): Initialize bidi_p from the default value of
14693 bidi-display-reordering, not from buffer-local value. Use the
14694 buffer-local value only if initializing for buffer iteration.
14695 (handle_invisible_prop): Support invisible properties on strings
14696 that are being bidi-reordered.
14697 (set_iterator_to_next): Support bidi reordering of C strings and
14699 (next_element_from_string): Support bidi reordering of Lisp
14701 (handle_stop_backwards): Support Lisp strings as well.
14702 (display_string): Support display of R2L glyph rows.
14703 Use IT_STRING_CHARPOS when displaying from a Lisp string.
14704 (init_iterator): Don't initialize it->bidi_p for strings
14706 (reseat_to_string): Initialize it->bidi_p for strings here.
14707 (next_element_from_string, next_element_from_c_string)
14708 (next_element_from_buffer): Add xassert's for correspondence
14709 between IT's object being iterated and it->bidi_it.string
14711 (face_before_or_after_it_pos): Support bidi iteration.
14712 (next_element_from_c_string): Handle the case of the first string
14713 character that is not the first one in the visual order.
14714 (get_visually_first_element): New function, refactored from common
14715 parts of next_element_from_buffer, next_element_from_string, and
14716 next_element_from_c_string.
14717 (tool_bar_lines_needed, redisplay_tool_bar)
14718 (display_menu_bar): Force left-to-right direction. Add a FIXME
14719 comment for making that be controlled by a user option.
14720 (push_it, pop_it): Save and restore the state of the
14721 bidi iterator. Save and restore the bidi_p flag.
14722 (pop_it): Iterate out of display property for string iteration as
14724 (iterate_out_of_display_property): Support iteration over strings.
14725 (handle_single_display_spec): Set up it->bidi_it for iteration
14726 over a display string, and call bidi_init_it.
14727 (handle_single_display_spec, next_overlay_string)
14728 (get_overlay_strings_1, push_display_prop): Set up the bidi
14729 iterator for displaying display or overlay strings.
14730 (forward_to_next_line_start): Don't use the shortcut if
14732 (back_to_previous_visible_line_start): If handle_display_prop
14733 pushed the iterator stack, restore the internal state of the bidi
14734 iterator by calling bidi_pop_it same number of times.
14735 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
14736 and we are bidi-iterating, don't decrement the iterator position;
14737 instead, set the first_elt flag in the bidi iterator, to produce
14739 (reseat_1): Remove redundant setting of string_from_display_prop_p.
14740 (push_display_prop): xassert that we are iterating a buffer.
14741 (push_it, pop_it): Save and restore paragraph_embedding member.
14742 (handle_single_display_spec, next_overlay_string)
14743 (get_overlay_strings_1, reseat_1, reseat_to_string)
14744 (push_display_prop): Set up the `unibyte' member of bidi_it.string
14745 correctly. Don't assume unibyte strings are not bidi-reordered.
14746 (compute_display_string_pos)
14747 (compute_display_string_end): Fix handling the case of C string.
14748 (push_it, pop_it): Save and restore from_disp_prop_p.

15208 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
15210 Random fixes. E.g., (random) never returned negative values.
15211 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
15212 subseconds part to the entropy, as that's a bit more random.
15213 Prefer signed to unsigned, since the signedness doesn't matter and
15214 in general we prefer signed. When given a limit, use a
15215 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
15216 latter isn't right if USE_2_TAGS_FOR_INTS.
15217 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
15218 not 0..VALMASK. Don't discard "excess" bits that random () returns.
15220 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
15222 * textprop.c (text_property_stickiness):
15223 Obey Vtext_property_default_nonsticky.

15230 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
15231 This is more efficient than Ffile_directory_p and avoids a minor race.
15233 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
15235 * buffer.c (Foverlay_put): Say what the return value is
15238 * fileio.c (barf_or_query_if_file_exists): Check first if the file
15239 is a directory before asking whether to use the file name
15241 (barf_or_query_if_file_exists): Make the "File is a directory"
15242 error be more correct.
15244 * fns.c (Frequire): Remove the mention of the .gz files, since
15245 that's installation-specific, but keep the mention of
15246 `get-load-suffixes'.
15248 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
15250 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

15255 * gnutls.c (Fgnutls_boot): Don't mention :verify-error.
15256 (syms_of_gnutls): Remove duplicate DEFSYM for
15257 Qgnutls_bootprop_verify_hostname_error, an error for
15258 Qgnutls_bootprop_verify_error (which is no longer used).
15260 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
15261 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
15262 Also (re)move comments that are misplaced or no longer relevant.
15264 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15266 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

15270 * xfaces.c (Finternal_merge_in_global_face): Modify the foreground
15271 and background color parameters if they have been changed.

15291 * lread.c (syms_of_lread): Mention single symbols defined by
15292 `defvar' or `defconst' (bug#7154).
15294 * fns.c (Frequire): Mention .el.gz files (bug#7314).
15295 (Frequire): Mention get-load-suffixes.
15297 2011-07-02 Martin Rudalics <rudalics@gmx.at>
15299 * window.h (window): Remove clone_number slot.

15325 (syms_of_keymap): Defsubr make-composed-keymap.
15326 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

15363 * eval.c (struct backtrace): Simplify and port the data structure.
15364 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
15365 signed bit field, as this assumption is not portable and it makes
15366 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
15367 "char debug_on_exit : 1" as this is not portable either; instead,
15368 use the portable "unsigned int debug_on_exit : 1". Remove unused
15369 member evalargs. Remove obsolete comments about cc bombing out.
15371 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>
15373 * xsettings.c: Include glib-object.h, gio/gio.h if HAVE_GSETTINGS.

15439 (emacs_fixed_new): Set priv->f to argument.
15440 (emacs_fixed_get_preferred_width)
15441 (emacs_fixed_get_preferred_height): Use min_width/height from
15442 frames size_hint to set minimum and natural (Bug#8919).
15443 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
15444 and use min_width/height from frames size_hint to set
15445 min_width/height (Bug#8919).

15537 * print.c (printchar, strout): Check for string overflow.
15538 (PRINTPREPARE, printchar, strout):
15539 Don't set size unless allocation succeeds.
15541 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
15542 for sizes. Check for string overflow more accurately.

15546 * keyboard.h (struct keyboard.kbd_macro_bufsize):
15547 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

15555 * lread.c: Integer overflow fixes.
15556 (read_integer): Radix is now EMACS_INT, not int,
15557 to improve quality of diagnostics for out-of-range radices.
15558 Calculate buffer size correctly for out-of-range radices.
15559 (read1): Check for integer overflow in radices, and in
15560 read-circle numbers.
15561 (read_escape): Avoid int overflow.
15562 (Fload, openp, read_buffer_size, read1)
15563 (substitute_object_recurse, read_vector, read_list, map_obarray):
15564 Use ptrdiff_t, not int, for sizes.

15584 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
15586 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
15587 The following patches are for when GLYPH_DEBUG && !XASSERT.
15588 * dispextern.h (trace_redisplay_p, dump_glyph_string):
15589 * dispnew.c (flush_stdout):
15590 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
15591 Mark as externally visible.
15592 * dispnew.c (check_window_matrix_pointers): Now static.
15593 * dispnew.c (window_to_frame_vpos):
15594 * xfns.c (unwind_create_frame):
15595 * xterm.c (x_check_font): Remove unused local.
15596 * scroll.c (CHECK_BOUNDS):
15597 * xfaces.c (cache_fache): Rename local to avoid shadowing.
15598 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.

15600 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
15601 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
15603 (debug_method_add): Use va_list and vsprintf rather than relying
15604 on undefined behavior with wrong number of arguments.
15605 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
15606 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
15607 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
15608 since we're not interested in debugging glyphs with old libraries.
15609 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
15610 GCC 4.6.0's static checking.
15612 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
15614 Integer overflow and signedness fixes (Bug#8873).

15628 * xfaces.c (load_pixmap):
15629 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
15630 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
15631 (.bitmaps_last, struct x_output.icon_bitmap):
15632 Use ptrdiff_t, not int, for bitmap indexes.
15633 (x_allocate_bitmap_record): Check for size overflow.
15634 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
15636 Use ptrdiff_t, not int, for overlay counts.
15637 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
15638 * editfns.c (overlays_around, get_pos_property):
15639 * textprop.c (get_char_property_and_overlay):
15640 * xdisp.c (next_overlay_change, note_mouse_highlight):
15641 * xfaces.c (face_at_buffer_position):
15642 * buffer.c (OVERLAY_COUNT_MAX): New macro.
15643 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
15644 (Fnext_overlay_change, Fprevious_overlay_change)
15645 (mouse_face_overlay_overlaps, Foverlays_in):
15646 Use ptrdiff_t, not int, for sizes.
15647 (overlays_at, overlays_in): Check for size-calculation overflow.
15649 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
15651 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
15652 (x_session_initialize): Do not assume string length fits in int.
15654 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
15655 This is unlikely, but can occur if DPI is outlandish.
15657 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
15658 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
15660 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
15661 * xrdb.c (magic_file_p, search_magic_path):
15662 Omit last arg SUFFIX; it was always 0. All callers changed.
15663 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
15665 * xfont.c (xfont_match): Avoid need for strlen.
15667 * xfns.c: Don't assume strlen fits in int.
15668 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
15670 * xdisp.c (message_log_check_duplicate): Return intmax_t,
15671 not unsigned long, as we prefer signed integers. All callers changed.
15672 Detect integer overflow in repeat count.
15673 (message_dolog): Don't assume print length fits in 39 bytes.
15674 (display_mode_element): Don't assume strlen fits in int.
15676 * termcap.c: Don't assume sizes fit in int and never overflow.
15677 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
15678 (gobble_line): Check for size-calculation overflow.
15680 * minibuf.c (Fread_buffer):
15681 * lread.c (intern, intern_c_string):
15682 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
15683 Don't assume string length fits in int.
15685 * keyboard.c (parse_tool_bar_item):
15686 * gtkutil.c (style_changed_cb): Avoid need for strlen.
15688 * font.c: Don't assume string length fits in int.
15689 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
15690 Use ptrdiff_t, not int.
15691 (font_intern_prop): Don't assume string length fits in int.
15692 Don't assume integer property fits in fixnum.
15693 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
15695 * filelock.c: Fix some buffer overrun and integer overflow issues.
15696 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
15697 Reformulate so as not to need the command string.
15698 Invoke gzip -cd rather than gunzip, as it's more portable.
15699 (lock_info_type, lock_file_1, lock_file):
15700 Don't assume pid_t and time_t fit in unsigned long.
15701 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
15702 (current_lock_owner): Prefer signed type for sizes.
15703 Use memcpy, not strncpy, where memcpy is what is really wanted.
15704 Don't assume (via atoi) that time_t and pid_t fit in int.
15705 Check for time_t and/or pid_t out of range, e.g., via a network share.
15706 Don't alloca where an auto var works fine.
15708 * fileio.c: Fix some integer overflow issues.
15709 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
15710 Don't assume string length fits in int.
15711 (directory_file_name): Don't assume string length fits in long.
15712 (make_temp_name): Don't assume pid fits in int, or that its print
15713 length is less than 20.
15715 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
15717 * coding.c (make_subsidiaries): Don't assume string length fits in int.
15719 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
15721 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
15722 We prefer signed integers, even for size calculations.
15724 * emacs.c: Don't assume string length fits in 'int'.
15725 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
15726 (main): Don't invoke strlen when not needed.
15728 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
15729 (XD_DEBUG_MESSAGE): Don't waste a byte.
15731 * callproc.c (getenv_internal_1, getenv_internal)
15732 (Fgetenv_internal):
15733 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
15735 * lread.c (invalid_syntax): Omit length argument.
15736 All uses changed. This doesn't fix a bug, but it simplifies the
15737 code away from its former Hollerith-constant appearance, and it's
15738 one less 'int' to worry about when looking at integer-overflow issues.
15739 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
15741 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
15742 This didn't break anything, but it didn't help either.
15743 It's confusing to put a bogus integer in a place where the actual
15744 value does not matter.
15745 (LIST_END_P): Remove unused macro and its bogus comment.
15746 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
15748 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
15749 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
15751 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
15752 We prefer signed types, and the value cannot exceed the EMACS_INT
15753 range anyway (because otherwise the length would not be representable).
15754 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
15755 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
15756 This avoids a GCC warning when WIDE_EMACS_INT.
15758 * indent.c (sane_tab_width): New function.
15759 (current_column, scan_for_column, Findent_to, position_indentation)
15760 (compute_motion): Use it. This is just for clarity.
15761 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
15763 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
15765 * lisp.h (lint_assume): New macro.
15766 * composite.c (composition_gstring_put_cache):
15767 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
15769 * editfns.c, insdel.c:
15770 Omit unnecessary forward decls, to simplify future changes.
15772 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
15774 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
15776 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
15777 Use much-faster test for byte-length change.
15778 Don't assume string byte-length fits in 'int'.
15779 Check that character arg fits in 'int'.
15780 (mapcar1): Declare byte as byte, for clarity.
15782 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
15784 * fns.c (concat): Catch string overflow earlier.
15785 Do not rely on integer wraparound.
15787 * dispextern.h (struct it.overlay_strings_charpos)
15788 (struct it.selective): Now EMACS_INT, not int.
15789 * xdisp.c (forward_to_next_line_start)
15790 (back_to_previous_visible_line_start)
15791 (reseat_at_next_visible_line_start, next_element_from_buffer):
15792 Don't arbitrarily truncate the value of 'selective' to int.
15794 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
15796 * composite.c: Don't truncate sizes to 'int'.
15797 (composition_gstring_p, composition_reseat_it)
15798 (composition_adjust_point): Use EMACS_INT, not int.
15799 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
15800 not EMACS_UINT, for indexes.
15802 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
15804 * buffer.c: Include <verify.h>.
15805 (struct sortvec.priority, struct sortstr.priority):
15806 Now EMACS_INT, not int.
15807 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
15808 (struct sortstr.size, record_overlay_string)
15809 (struct sortstrlist.size, struct sortlist.used):
15810 Don't truncate size to int.
15811 (record_overlay_string): Check for size-calculation overflow.
15812 (init_buffer_once): Check at compile-time, not run-time.
15814 2011-06-22 Jim Meyering <meyering@redhat.com>
15816 Don't leak an XBM-image-sized buffer
15817 * image.c (xbm_load): Free the image buffer after using it.
15819 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
15822 * composite.c (find_automatic_composition): Omit needless 'return 0;'
15823 that Sun C diagnosed.
15824 * fns.c (secure_hash): Fix pointer signedness issue.
15825 * intervals.c (static_offset_intervals): New function.
15826 (offset_intervals): Use it.
15828 2011-06-21 Leo Liu <sdl.web@gmail.com>
15831 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
15834 * fns.c (secure_hash): Rename from crypto_hash_function and change
15835 the first arg to accept symbols.
15836 (Fsecure_hash): New primitive.
15837 (syms_of_fns): New symbols.
15839 2011-06-20 Deniz Dogan <deniz@dogan.se>
15841 * process.c (Fset_process_buffer): Clarify return value in
15844 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
15846 * dispnew.c (add_window_display_history): Use BVAR.
15848 * xdisp.c (debug_method_add): Use BVAR.
15849 (check_window_end, dump_glyph_matrix, dump_glyph)
15850 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
15852 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
15855 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
15856 check till after the cache is created in init_frame_faces.
15858 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
15860 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
15862 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
15864 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
15865 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
15866 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
15868 Improve buffer-overflow checking (Bug#8873).
15869 * fileio.c (Finsert_file_contents):
15870 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
15871 Remove the old (too-loose) buffer overflow checks.
15872 They weren't needed, since make_gap checks for buffer overflow.
15873 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
15874 The old code merely checked for Emacs fixnum overflow, and relied
15875 on undefined (wraparound) behavior. The new code avoids undefined
15876 behavior, and also checks for ptrdiff_t and/or size_t overflow.
15878 * editfns.c (Finsert_char): Don't dump core with very negative counts.
15879 Tune. Don't use wider integers than needed. Don't use alloca.
15880 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
15882 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
15884 * insdel.c, lisp.h (buffer_overflow): New function.
15885 (insert_from_buffer_1, replace_range, replace_range_2):
15886 * insdel.c (make_gap_larger):
15887 * editfns.c (Finsert_char):
15888 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
15890 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
15892 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
15894 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
15896 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
15897 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
15899 * fileio.c: Don't assume EMACS_INT fits in off_t.
15900 (emacs_lseek): New static function.
15901 (Finsert_file_contents, Fwrite_region): Use it.
15902 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
15904 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
15906 * fns.c: Don't overflow int when computing a list length.
15907 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
15908 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
15909 truncation on 64-bit hosts. Check for QUIT every
15910 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
15911 faster and is responsive enough.
15912 (Flength): Report an error instead of overflowing an integer.
15913 (Fsafe_length): Return a float if the value is not representable
15914 as a fixnum. This shouldn't happen except in contrived situations.
15915 (Fnthcdr, Fsort): Don't assume list length fits in int.
15916 (Fcopy_sequence): Don't assume vector length fits in int.
15918 * alloc.c: Check that resized vectors' lengths fit in fixnums.
15919 (header_size, word_size): New constants.
15920 (allocate_vectorlike): Don't check size overflow here.
15921 (allocate_vector): Check it here instead, since this is the only
15922 caller of allocate_vectorlike that could cause overflow.
15923 Check that the new vector's length is representable as a fixnum.
15925 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
15926 The previous code was bogus. For example, next_almost_prime (32)
15927 returned 39, which is undesirable as it is a multiple of 3; and
15928 next_almost_prime (24) returned 25, which is a multiple of 5 so
15929 why was the code bothering to check for multiples of 7?
15931 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
15933 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
15935 Variadic C functions now count arguments with ptrdiff_t.
15936 This partly undoes my 2011-03-30 change, which replaced int with size_t.
15937 Back then I didn't know that the Emacs coding style prefers signed int.
15938 Also, in the meantime I found a few more instances where arguments
15939 were being counted with int, which may truncate counts on 64-bit
15940 machines, or EMACS_INT, which may be unnecessarily wide.
15941 * lisp.h (struct Lisp_Subr.function.aMANY)
15942 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
15943 Arg counts are now ptrdiff_t, not size_t.
15944 All variadic functions and their callers changed accordingly.
15945 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
15946 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
15947 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
15948 * callint.c (Fcall_interactively): Check arg count for overflow,
15949 to avoid potential buffer overrun. Use signed char, not 'int',
15950 for 'varies' array, so that we needn't bother to check its size
15951 calculation for overflow.
15952 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
15953 * eval.c (apply_lambda):
15954 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
15955 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
15956 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
15958 * callint.c (Fcall_interactively): Don't use index var as event count.
15960 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
15961 * mem-limits.h (SIZE): Remove; no longer used.
15963 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
15965 Remove unnecessary casts.
15966 * xterm.c (x_term_init):
15967 * xfns.c (x_set_border_pixel):
15968 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
15969 These aren't needed now that we assume ANSI C.
15971 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
15972 It's more likely to cause problems (due to unsigned overflow)
15975 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
15977 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
15979 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
15981 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
15983 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
15985 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
15987 GLYPH_CODE_FACE returns EMACS_INT, not int.
15988 * dispextern.h (merge_faces):
15989 * xfaces.c (merge_faces):
15990 * xdisp.c (get_next_display_element, next_element_from_display_vector):
15991 Don't assume EMACS_INT fits in int.
15993 * character.h (CHAR_VALID_P): Remove unused parameter.
15994 * fontset.c, lisp.h, xdisp.c: All uses changed.
15996 * editfns.c (Ftranslate_region_internal): Omit redundant test.
15998 * fns.c (concat): Minor tuning based on overflow analysis.
15999 This doesn't fix any bugs. Use int to hold character, instead
16000 of constantly refetching from Emacs object. Use XFASTINT, not
16001 XINT, for value known to be a character. Don't bother comparing
16002 a single byte to 0400, as it's always less.
16004 * floatfns.c (Fexpt):
16005 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
16007 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
16010 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
16012 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
16013 Without this fix, on a 64-bit host (aset S 0 4294967386) would
16014 incorrectly succeed when S was a string, because 4294967386 was
16015 truncated before it was used.
16017 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
16018 Otherwise, an out-of-range integer could cause undefined behavior
16021 * composite.c: Use int, not EMACS_INT, for characters.
16022 (fill_gstring_body, composition_compute_stop_pos): Use int, not
16023 EMACS_INT, for values that are known to be in character range.
16024 This doesn't fix any bugs but is the usual style inside Emacs and
16025 may generate better code on 32-bit machines.
16027 Make sure a 64-bit char is never passed to ENCODE_CHAR.
16028 This is for reasons similar to the recent CHAR_STRING fix.
16029 * charset.c (Fencode_char): Check that character arg is actually
16030 a character. Pass an int to ENCODE_CHAR.
16031 * charset.h (ENCODE_CHAR): Verify that the character argument is no
16032 wider than 'int', as a compile-time check to prevent future regressions
16035 * character.c (char_string): Remove unnecessary casts.
16037 Make sure a 64-bit char is never passed to CHAR_STRING.
16038 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
16039 by silently ignoring the top 32 bits, allowing some values
16040 that were far too large to be valid characters.
16041 * character.h: Include <verify.h>.
16042 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
16043 arguments are no wider than unsigned, as a compile-time check
16044 to prevent future regressions in this area.
16046 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
16047 (Fsubst_char_in_region):
16049 * xdisp.c (decode_mode_spec_coding):
16050 Adjust to CHAR_STRING's new requirement.
16051 * editfns.c (Finsert_char, Fsubst_char_in_region):
16052 * fns.c (concat): Check that character args are actually
16053 characters. Without this test, these functions did the wrong
16054 thing with wildly out-of-range values on 64-bit hosts.
16056 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
16057 These casts should not be needed on 32-bit hosts, either.
16058 * keyboard.c (read_char):
16059 * lread.c (Fload): Remove casts to unsigned.
16061 * lisp.h (UNSIGNED_CMP): New macro.
16062 This fixes comparison bugs on 64-bit hosts.
16063 (ASCII_CHAR_P): Use it.
16064 * casefiddle.c (casify_object):
16065 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
16066 (SINGLE_BYTE_CHAR_P, CHAR_STRING):

16119 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
16120 when a (possibly-narrower) signed value would do just as well.
16121 We prefer using signed arithmetic, to avoid comparison confusion.
16123 * alloc.c: Catch some string size overflows that we were missing.
16124 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
16125 for convenience in STRING_BYTES_MAX.
16126 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
16127 The definition here is exact; the one in lisp.h was approximate.
16128 (allocate_string_data): Check for string overflow. This catches
16129 some instances we weren't catching before. Also, it catches
16130 size_t overflow on (unusual) hosts where SIZE_MAX <= min
16131 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
16132 and ptrdiff_t and EMACS_INT are both 64 bits.
16134 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
16135 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.

16713 instead of using explicit *_CHAR codes.
16714 (bidi_resolve_explicit, bidi_resolve_weak):

16723 (bidi_level_of_next_char): Don't try to lookup the cache for the
16724 next/previous character if nothing is cached there yet, or if we
16725 were just reseat()'ed to a new position.
16727 * xdisp.c (set_cursor_from_row): Set start and stop points
16728 according to the row's direction when priming the loop that looks
16729 for the glyph on which to display cursor.

16731 (display_prop_intangible_p): Reimplement to call
16732 handle_display_spec instead of single_display_spec_intangible_p.
16733 Accept 3 additional arguments needed by handle_display_spec.
16734 This fixes incorrect cursor motion across display property with complex

16743 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
16744 value of a `display' property is a "replacing spec".
16745 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
16746 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
16747 the display property, but just return a value indicating whether
16748 the display property will replace the characters it covers.
16749 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
16750 frame_window_p members of struct bidi_it.
16751 (compute_display_string_pos, compute_display_string_end):

16776 * gnutls.c: Use Emacs's memory allocators.
16777 Without this change, the gnutls library would invoke malloc etc.
16778 directly, which causes problems on non-SYNC_INPUT hosts, and which
16779 runs afoul of improving memory_full behavior. (Bug#8761)
16780 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
16781 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
16782 xfree instead of the default malloc, realloc, free.
16783 (Fgnutls_boot): No need to check for memory allocation failure,
16784 since xmalloc does that for us.

16806 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
16807 for hashes and hash indexes, instead of 'unsigned' and 'int'.
16808 * alloc.c (allocate_vectorlike):
16809 Check for overflow in vector size calculations.
16810 * ccl.c (ccl_driver):
16811 Check for overflow when converting EMACS_INT to int.

16813 need to be updated by these changes.
16814 * fns.c (make_hash_table, maybe_resize_hash_table):
16815 Check for integer overflow with large hash tables.
16816 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
16817 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
16818 (SXHASH_REDUCE): New macro.
16819 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
16820 Use it instead of discarding useful hash info with large hash values.
16821 (sxhash_float): New function.
16822 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
16823 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
16824 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
16825 Rewrite to use FIXNUM_BITS, as this simplifies things.
16826 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
16827 Adjust signatures to match updated version of code.
16828 (consing_since_gc): Now EMACS_INT, since a single hash table can
16829 use more than INT_MAX bytes.

16878 Make it possible to run ./temacs.
16880 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
16881 syms_of_callproc does the same thing. Remove test for

16939 2011-05-28 Jim Meyering <meyering@redhat.com>
16941 Avoid a sign-extension bug in crypto_hash_function.
16942 * fns.c (to_uchar): Define.
16943 (crypto_hash_function): Use it to convert some newly-signed
16944 variables to unsigned, to avoid sign-extension bugs. For example,
16945 without this change, (md5 "truc") would evaluate to
16946 45723a2aff78ff4fff7fff1114760e62 rather than the expected
16947 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
16948 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
16950 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
16952 Integer overflow fixes.
16954 * dbusbind.c: Serial number integer overflow fixes.
16955 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
16956 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
16957 to hold a serial number that is too large for a fixnum.
16958 (Fdbus_method_return_internal, Fdbus_method_error_internal):
16959 Check for serial numbers out of range. Decode any serial number
16960 that was so large that it became a float. (Bug#8722)
16962 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
16963 (Fdbus_call_method, Fdbus_call_method_asynchronously):
16964 Use XFASTINT rather than XUINT when numbers are nonnegative.
16965 (xd_append_arg, Fdbus_method_return_internal):
16966 (Fdbus_method_error_internal): Likewise. Also, for unsigned
16967 arguments, check that Lisp number is nonnegative, rather than
16968 silently wrapping negative numbers around. (Bug#8722)
16969 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
16972 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
16974 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
16976 ccl: Add integer overflow checks.
16977 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
16978 (IN_INT_RANGE): New macros.
16979 (ccl_driver): Use them to check for integer overflow when
16980 decoding a CCL program. Many of the new checks are whether XINT (x)
16981 fits in int; it doesn't always, on 64-bit hosts. The new version
16982 doesn't catch all possible integer overflows, but it's an
16983 improvement. (Bug#8719)
16985 * alloc.c (make_event_array): Use XINT, not XUINT.
16986 There's no need for unsigned here.
16988 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
16989 This follows up to the 2011-05-06 change that substituted uintptr_t
16990 for EMACS_INT. This case wasn't caught back then.
16992 Rework Fformat to avoid integer overflow issues.
16993 * editfns.c: Include <float.h> unconditionally, as it's everywhere
16994 now (part of C89). Include <verify.h>.
16995 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
16996 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
16997 (Fformat): Avoid the prepass trying to compute sizes; it was only
16998 approximate and thus did not catch overflow reliably. Instead, walk
16999 through the format just once, formatting and computing sizes as we go,
17000 checking for integer overflow at every step, and allocating a larger
17001 buffer as needed. Keep track separately whether the format is
17002 multibyte. Keep only the most-recently calculated precision, rather
17003 than them all. Record whether each argument has been converted to
17004 string. Use EMACS_INT, not int, for byte and char and arg counts.
17005 Support field widths and precisions larger than INT_MAX. Avoid
17006 sprintf's undefined behavior with conversion specifications such as %#d
17007 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
17008 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
17009 formatting out-of-range floating point numbers with int
17010 formats. (Bug#8668)
17012 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
17014 * data.c: Avoid integer truncation in expressions involving floats.
17015 * data.c: Include <intprops.h>.
17016 (arith_driver): When there's an integer overflow in an expression
17017 involving floating point, convert the integers to floating point
17018 so that the resulting value does not suffer from catastrophic
17019 integer truncation. For example, on a 64-bit host (* 4
17020 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
17021 Do not rely on undefined behavior after integer overflow.
17023 merge count_size_as_multibyte, parse_str_to_multibyte
17024 * character.c, character.h (count_size_as_multibyte):
17025 Rename from parse_str_to_multibyte; all uses changed.
17026 Check for integer overflow.
17027 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
17028 since it's now a duplicate of the other. This is more of
17029 a character than a buffer op, so better that it's in character.c.
17030 * fns.c, print.c: Adjust to above changes.
17032 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
17034 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
17036 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17038 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17039 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
17040 (x_clipboard_manager_save): Now static.
17041 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
17043 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17044 (crypto_hash_function): Now static.
17045 Fix pointer signedness problems. Avoid unnecessary initializations.
17047 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
17049 * termhooks.h (Vselection_alist): Make it terminal-local.
17051 * terminal.c (create_terminal): Initialize it.
17053 * xselect.c: Support for clipboard managers.
17054 (Vselection_alist): Move to termhooks.h as terminal-local var.
17055 (LOCAL_SELECTION): New macro.
17056 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
17057 (symbol_to_x_atom): Remove gratuitous arg.
17058 (x_handle_selection_request, lisp_data_to_selection_data)
17059 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
17060 (x_own_selection, x_get_local_selection, x_convert_selection):
17061 New arg, specifying work frame. Use terminal-local Vselection_alist.
17062 (some_frame_on_display): Delete unused function.
17063 (Fx_own_selection_internal, Fx_get_selection_internal)
17064 (Fx_disown_selection_internal, Fx_selection_owner_p)
17065 (Fx_selection_exists_p): New optional frame arg.
17066 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
17067 (x_handle_selection_clear): Don't treat other terminals with the
17068 same keyboard specially. Use the terminal-local Vselection_alist.
17069 (x_clear_frame_selections): Use Frun_hook_with_args.
17071 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
17073 * xterm.h: Add support for those atoms.
17075 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
17077 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
17078 (converted_selections, conversion_fail_tag): New global variables.
17079 (x_selection_request_lisp_error): Free the above.
17080 (x_get_local_selection): Remove unnecessary code.
17081 (x_reply_selection_request): Args changed; handle arbitrary array
17082 of converted selections stored in converted_selections.
17083 Separate the XChangeProperty and SelectionNotify steps.
17084 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
17085 (x_convert_selection): New function.
17086 (x_handle_selection_event): Simplify.
17087 (x_get_foreign_selection): Don't ignore incoming requests while
17088 waiting for an answer; this will fail when we implement
17089 SAVE_TARGETS, and seems unnecessary anyway.
17090 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
17091 (Vx_sent_selection_functions): Doc fix.
17093 2011-05-26 Leo Liu <sdl.web@gmail.com>
17095 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
17097 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17099 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
17101 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
17102 for fringe update if it has periodic bitmap.
17103 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
17104 and fringe_bitmap_periodic_p.
17106 * fringe.c (get_fringe_bitmap_data): New function.
17107 (draw_fringe_bitmap_1, update_window_fringes): Use it.
17108 (update_window_fringes): Record periodicity of fringe bitmap in glyph
17109 row. Mark glyph row for fringe update if periodicity changed.
17111 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
17112 for fringe update unless it has periodic bitmap.
17114 2011-05-25 Kenichi Handa <handa@m17n.org>
17116 * xdisp.c (get_next_display_element): Set correct it->face_id for
17117 a static composition.
17119 2011-05-24 Leo Liu <sdl.web@gmail.com>
17122 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
17124 * fns.c (crypto_hash_function, Fsha1): New function.
17125 (Fmd5): Use crypto_hash_function.
17126 (syms_of_fns): Add Ssha1.
17128 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
17130 * gnutls.c: Remove unused macros.
17131 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
17132 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
17133 Remove macros that are defined and never used.
17134 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
17136 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17138 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
17139 (Fx_get_selection_internal): Minor cleanup.
17140 (Fx_own_selection_internal): Rename arguments for consistency with
17143 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
17145 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
17147 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17149 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
17151 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17153 * dispnew.c (scrolling_window): Don't exclude the case that the
17154 last enabled row in the desired matrix touches the bottom boundary.
17156 2011-05-21 Glenn Morris <rgm@gnu.org>
17158 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
17159 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
17160 and add some more files.
17162 2011-05-20 Eli Zaretskii <eliz@gnu.org>
17164 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
17165 report_file_error introduced by the change from 2011-05-07.
17167 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
17169 * systime.h (Time): Define only if emacs is defined.
17170 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
17171 where the include path doesn't have X11/X.h by default. See
17172 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
17174 2011-05-20 Kenichi Handa <handa@m17n.org>
17176 * composite.c (find_automatic_composition): Fix previous change.
17178 2011-05-20 Glenn Morris <rgm@gnu.org>
17180 * lisp.mk: New file, split from Makefile.in.
17181 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
17182 (shortlisp): Remove.
17183 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
17185 2011-05-19 Glenn Morris <rgm@gnu.org>
17187 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
17188 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
17189 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
17190 (lisp): Set the order to that of loadup.el.
17191 (shortlisp): Make it a copy of $lisp.
17192 (SOME_MACHINE_LISP): Remove.
17193 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
17194 Use just $shortlisp, not $SOME_MACHINE_LISP too.
17196 2011-05-18 Kenichi Handa <handa@m17n.org>
17198 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
17199 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
17200 (find_automatic_composition): Mostly rewrite for efficiency.
17202 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
17204 * makefile.w32-in: Update dependencies.
17206 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
17208 * menu.c: Include limits.h (fixes the MS-Windows build broken by
17209 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
17211 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
17213 Fix some integer overflow issues, such as string length overflow.
17215 * insdel.c (count_size_as_multibyte): Check for string overflow.
17217 * character.c (lisp_string_width): Check for string overflow.
17218 Use EMACS_INT, not int, for string indexes and lengths; in
17219 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
17220 the resulting string length overflows an EMACS_INT; instead,
17221 report a string overflow if no precision given. When checking for
17222 precision exhaustion, use a check that cannot possibly have
17223 integer overflow. (Bug#8675)
17224 * character.h (lisp_string_width): Adjust to new signature.
17226 * alloc.c (string_overflow): New function.
17227 (Fmake_string): Use it. This doesn't change behavior, but saves
17228 a few bytes and will simplify future changes.
17229 * character.c (string_escape_byte8): Likewise.
17230 * lisp.h (string_overflow): New decl.
17232 Fixups, following up to the user-interface timestamp change.
17233 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
17234 for UI timestamps, instead of unsigned long.
17235 * msdos.c (mouse_get_pos): Likewise.
17236 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
17237 * w32gui.h (Time): Define by including "systime.h" rather than by
17238 declaring it ourselves. (Bug#8664)
17240 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
17241 * image.c (clear_image_cache): Likewise.
17243 * term.c (term_mouse_position): Don't assume time_t wraparound.
17245 Be more systematic about user-interface timestamps.
17246 Before, the code sometimes used 'Time', sometimes 'unsigned long',
17247 and sometimes 'EMACS_UINT', to represent these timestamps.
17248 This change causes it to use 'Time' uniformly, as that's what X uses.
17249 This makes the code easier to follow, and makes it easier to catch
17250 integer overflow bugs such as Bug#8664.
17251 * frame.c (Fmouse_position, Fmouse_pixel_position):
17252 Use Time, not unsigned long, for user-interface timestamps.
17253 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
17254 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
17255 * keyboard.h (last_event_timestamp): Likewise.
17256 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
17257 * menu.h (xmenu_show): Likewise.
17258 * term.c (term_mouse_position): Likewise.
17259 * termhooks.h (struct input_event.timestamp): Likewise.
17260 (struct terminal.mouse_position_hook): Likewise.
17261 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
17262 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
17263 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
17264 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
17265 what it was before.
17266 * menu.h, termhooks.h: Include "systime.h", for Time.
17268 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
17269 Don't assume that the difference between two unsigned long values
17270 can fit into an integer. At this point, we know button_down_time
17271 <= event->timestamp, so the difference must be nonnegative, so
17272 there's no need to cast the result if double-click-time is
17273 nonnegative, as it should be; check that it's nonnegative, just in
17274 case. This bug is triggered when events are more than 2**31 ms
17275 apart (about 25 days). (Bug#8664)
17277 * xselect.c (last_event_timestamp): Remove duplicate decl.
17278 (x_own_selection): Remove needless cast to unsigned long.
17280 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
17281 that always fit in int. Use a sentinel instead of a counter, to
17282 avoid a temp and to allay GCC's concerns about possible int overflow.
17283 * frame.h (struct frame): Use int for menu_bar_items_used
17284 instead of EMACS_INT, since it always fits in int.
17286 * menu.c (grow_menu_items): Check for int overflow.
17288 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
17290 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
17291 Before, the code was not consistent. These values cannot exceed
17292 2**31 - 1 so there's no need to make them unsigned.
17293 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
17294 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
17295 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
17297 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
17299 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
17300 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
17301 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
17302 presumably because the widths might not match.
17304 * window.c (size_window): Avoid needless test at loop start.
17306 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
17308 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
17310 2011-05-12 Drew Adams <drew.adams@oracle.com>
17312 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
17314 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17316 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
17317 `width' to `bar_area_x' and `bar_area_width', respectively.
17318 (x_scroll_run): Take account of fringe background extension.
17320 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
17321 Rename local vars `left' and `width' to `bar_area_x' and
17322 `bar_area_width', respectively.
17323 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
17324 background extension.
17326 2011-05-10 Jim Meyering <meyering@redhat.com>
17328 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
17330 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
17332 * image.c (Finit_image_library): Return t for built-in image types,
17333 like pbm and xbm. (Bug#8640)
17335 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
17337 * w32menu.c (set_frame_menubar): Fix submenu allocation.
17339 2011-05-07 Eli Zaretskii <eliz@gnu.org>
17341 * w32console.c (Fset_screen_color): Doc fix.
17342 (Fget_screen_color): New function.
17343 (syms_of_ntterm): Defsubr it.
17345 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
17346 unlink the temporary file if Fcall_process didn't create it in the
17348 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
17349 child process will be redirected to a file specified with `:file'.
17350 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
17351 cue to call_process_cleanup not to close that handle.
17353 2011-05-07 Ben Key <bkey76@gmail.com>
17355 * makefile.w32-in: The bootstrap-temacs rule now makes use of
17356 one of two shell specific rules, either bootstrap-temacs-CMD or
17357 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
17358 to the previous implementation of the bootstrap-temacs rule.
17359 The bootstrap-temacs-CMD rule is similar to the previous
17360 implementation of the bootstrap-temacs rule except that it
17361 makes use of the ESC_CFLAGS variable instead of the CFLAGS
17364 These changes, along with some changes to nt/configure.bat,
17365 nt/gmake.defs, and nt/nmake.defs, are required to extend my
17366 earlier fix to add support for --cflags and --ldflags options
17367 that include quotes so that it works whether make uses cmd or
17370 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
17372 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
17373 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
17375 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
17376 a string. Handle both cases.
17377 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
17378 (Fdbus_register_method): Use Qinvalid_function.
17380 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
17382 * makefile.w32-in: Update dependencies.
17383 (LISP_H): Add inttypes.h and stdin.h.
17384 (PROCESS_H): Add unistd.h.
17386 2011-05-06 Eli Zaretskii <eliz@gnu.org>
17388 * lread.c: Include limits.h (fixes the MS-Windows build broken by
17389 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
17391 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
17393 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
17395 * term.c (vfatal): Remove stray call to va_end.
17396 It's not needed and the C Standard doesn't allow it here anyway.
17398 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
17399 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
17401 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
17404 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
17406 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
17408 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
17410 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
17412 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
17414 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
17415 * charset.c (Fdefine_charset_internal): Don't initialize
17416 charset.code_space[15]. The value was garbage, on hosts with
17417 32-bit int (Bug#8600).
17419 * lread.c (read_integer): Be more consistent with string-to-number.
17420 Use string_to_number to do the actual conversion; this avoids
17421 rounding errors and fixes some other screwups. Without this fix,
17422 for example, #x1fffffffffffffff was misread as -2305843009213693952.
17423 (digit_to_number): Move earlier, for benefit of read_integer.
17424 Return -1 if the digit is out of range for the base, -2 if it is
17425 not a digit in any supported base. (Bug#8602)
17427 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
17429 * dispnew.c (scrolling_window): Return 1 if we scrolled,
17430 to match comment at start of function. This also removes a
17431 GCC warning about overflow in a 32+64-bit port.
17433 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
17435 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
17436 Reported by Stefan Monnier in
17437 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
17438 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
17439 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
17441 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
17442 (EMACS_UINTPTR): Likewise, with uintptr_t.
17444 * lisp.h: Prefer 64-bit EMACS_INT if available.
17445 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
17446 on 32-bit hosts that have 64-bit int, so that they can access
17448 However, temporarily disable this change unless the temporary
17449 symbol WIDE_EMACS_INT is defined.
17451 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
17453 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
17454 This removes an assumption that EMACS_INT and long are the same
17455 width as pointers. The assumption is true for Emacs porting targets
17456 now, but we want to make other targets possible.
17457 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
17458 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
17459 In the rest of the code, change types of integers that hold casted
17460 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
17461 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
17462 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
17463 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
17464 No need to cast type when ORing.
17465 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
17466 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
17467 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
17468 assume EMACS_INT is the same width as char *.
17469 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
17470 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
17471 Remove no-longer-needed casts.
17472 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
17473 (xg_tool_bar_help_callback, xg_make_tool_item):
17474 Use EMACS_INTPTR to hold an integer
17475 that will be cast to void *; this can avoid a GCC warning
17476 if EMACS_INT is not the same width as void *.
17477 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
17478 * xdisp.c (display_echo_area_1, resize_mini_window_1):
17479 (current_message_1, set_message_1):
17480 Use a local to convert to proper width without a cast.
17481 * xmenu.c (dialog_selection_callback): Likewise.
17483 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
17484 Also, don't assume VALBITS / RAND_BITS is less than 5,
17485 and don't rely on undefined behavior when shifting a 1 left into
17487 * lisp.h (get_random): Change signature to match.
17489 * lread.c (hash_string): Use size_t, not int, for hash computation.
17490 Normally we prefer signed values; but hashing is special, because
17491 it's better to use unsigned division on hash table sizes so that
17492 the remainder is nonnegative. Also, size_t is the natural width
17493 for hashing into memory. The previous code used 'int', which doesn't
17494 retain enough info to hash well into very large tables.
17495 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
17497 * dbusbind.c: Don't possibly lose pointer info when converting.
17498 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
17499 Use XPNTR rather than XHASH, so that the high-order bits of
17500 the pointer aren't lost when converting through void *.
17502 * eval.c (Fautoload): Don't double-shift a pointer.
17504 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
17506 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
17508 * gnutls.c (DEF_GNUTLS_FN):
17509 * image.c (DEF_IMGLIB_FN): Make function pointers static.
17511 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
17513 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
17516 2011-05-05 Eli Zaretskii <eliz@gnu.org>
17518 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
17519 New version that can reserve upto 2GB of heap space.
17521 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
17523 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
17525 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
17527 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
17528 `gnutls_certificate_set_x509_key_file'.
17530 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
17532 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
17533 Update dependencies.
17535 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
17537 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
17538 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
17539 Remove unused parameter `fildes'.
17540 * process.c (read_process_output, send_process): Don't pass it.
17542 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
17544 Fix previous change: the library cache is defined in w32.c.
17545 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
17546 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
17548 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
17550 Implement dynamic loading of GnuTLS on Windows.
17552 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
17553 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
17554 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
17557 * gnutls.c (Qgnutls_dll): Define.
17558 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
17559 (gnutls_*): Declare function pointers.
17560 (init_gnutls_functions): New function to initialize function pointers.

17563 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
17564 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
17565 (emacs_gnutls_write, emacs_gnutls_read)
17566 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
17567 (Fgnutls_available_p): New function.
17568 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

17580 * w32.c (QCloaded_from, Vlibrary_cache): Define.
17581 (w32_delayed_load): Move from image.c. When loading a library, record
17582 its filename in the :loaded-from property of the library id.
17583 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
17584 Initialize and staticpro them.
17585 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
17587 * process.c: Include lisp.h before w32.h, not after.
17588 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
17589 instead of gnutls_record_check_pending.
17591 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
17593 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
17595 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
17596 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
17599 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
17601 * xterm.c (x_set_frame_alpha): Do not set property on anything
17602 else than FRAME_X_OUTER_WINDOW (Bug#8608).
17604 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
17606 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
17608 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
17610 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

17620 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
17622 * callproc.c: Indentation fixup.
17624 * sysdep.c (wait_for_termination_1): Make static.
17625 (wait_for_termination, interruptible_wait_for_termination):
17626 Move after wait_for_termination_1.
17628 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
17630 * sysdep.c (interruptible_wait_for_termination): New function
17631 which is like wait_for_termination, but allows keyboard
17634 * callproc.c (Fcall_process): Add (:file "file") as an option for
17636 (Fcall_process_region): Ditto.
17638 2011-04-30 Eli Zaretskii <eliz@gnu.org>
17640 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
17641 rather than `XVECTOR (FOO)->size'.
17643 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
17644 inttypes.h, as a gnulib replacement is used if it not available in
17647 2011-04-21 Eli Zaretskii <eliz@gnu.org>
17649 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
17650 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
17651 of MOST_POSITIVE_FIXNUM. (Bug#8528)
17653 * coding.c (coding_alloc_by_realloc): Error out if destination
17654 will grow beyond MOST_POSITIVE_FIXNUM.
17655 (decode_coding_emacs_mule): Abort if there isn't enough place in
17656 charbuf for the composition carryover bytes. Reserve an extra
17657 space for up to 2 characters produced in a loop.
17658 (decode_coding_iso_2022): Abort if there isn't enough place in
17659 charbuf for the composition carryover bytes.

17664 aborting when %lld or %lll format is passed.
17665 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
17666 %llo or %llx format is passed. (Bug#8545)
17668 * window.c (window_scroll_line_based): Use a marker instead of
17669 simple variables to record original value of point. (Bug#7952)
17671 * doprnt.c (doprnt): Fix the case where a multibyte sequence
17672 produced by %s or %c overflows available buffer space. (Bug#8545)
17674 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
17676 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

17705 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
17707 * makefile.w32-in: Update dependencies.
17709 2011-04-27 Eli Zaretskii <eliz@gnu.org>
17711 Improve `doprnt' and its usage. (Bug#8545)
17712 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
17713 `format_end'. Remove support for %l as a conversion specifier.
17714 Don't use xrealloc. Improve diagnostics when the %l size modifier
17715 is used. Update the commentary.
17717 * eval.c (verror): Simplify calculation of size_t.
17719 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
17722 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
17724 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
17727 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
17729 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
17730 This makes this file independent of the recent pseudovector change.
17732 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
17734 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
17736 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
17737 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
17738 Remove unused local.
17739 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
17741 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
17742 GCC 4.6.0 optimizes based on type-based alias analysis.
17743 For example, if b is of type struct buffer * and v of type struct
17744 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
17745 != &v->size, and therefore "v->size = 1; b->size = 2; return
17746 v->size;" must therefore return 1. This assumption is incorrect
17747 for Emacs, since it type-puns struct Lisp_Vector * with many other
17748 types. To fix this problem, this patch adds a new type struct
17749 vectorlike_header that documents the constraints on layout of vectors
17750 and pseudovectors, and helps optimizing compilers not get fooled
17751 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
17752 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
17753 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
17755 (XSETPVECTYPE): Rewrite in terms of new macro.
17756 (XSETPVECTYPESIZE): New macro, specifying both type and size.
17757 This is a bit clearer, and further avoids the possibility of
17758 undesirable aliasing.
17759 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
17760 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
17761 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
17762 since Lisp_Subr is a special case (no "next" field).
17763 (ASIZE): Now uses header.size rather than size.
17764 All previous uses of XVECTOR (foo)->size replaced to use this macro,
17765 to avoid the hassle of writing XVECTOR (foo)->header.size.
17766 (struct vectorlike_header): New type.
17767 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
17768 object, to help avoid aliasing.
17769 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
17770 (SUBRP): Likewise, since Lisp_Subr is a special case.
17771 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
17772 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
17773 (struct Lisp_Hash_Table): Combine first two members into a single
17774 struct vectorlike_header member. All uses of "size" and "next" members
17775 changed to be "header.size" and "header.next".
17776 * buffer.h (struct buffer): Likewise.
17777 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
17778 * frame.h (struct frame): Likewise.
17779 * process.h (struct Lisp_Process): Likewise.
17780 * termhooks.h (struct terminal): Likewise.
17781 * window.c (struct save_window_data, struct saved_window): Likewise.
17782 * window.h (struct window): Likewise.
17783 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
17784 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
17785 * buffer.c (init_buffer_once): Likewise.
17786 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
17788 * process.c (Fformat_network_address): Use local var for size,
17791 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
17793 Make the Lisp reader and string-to-float more consistent (Bug#8525)
17794 * data.c (atof): Remove decl; no longer used or needed.
17795 (digit_to_number): Move to lread.c.
17796 (Fstring_to_number): Use new string_to_number function, to be
17797 consistent with how the Lisp reader treats infinities and NaNs.
17798 Do not assume that floating-point numbers represent EMACS_INT
17799 without losing information; this is not true on most 64-bit hosts.
17800 Avoid double-rounding errors, by insisting on integers when
17801 parsing non-base-10 numbers, as the documentation specifies.
17802 * lisp.h (string_to_number): New decl, replacing ...
17803 (isfloat_string): Remove.
17804 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
17805 (read1): Do not accept +. and -. as integers; this
17806 appears to have been a coding error. Similarly, do not accept
17807 strings like +-1e0 as floating point numbers. Do not report
17808 overflow for integer overflows unless the base is not 10 which
17809 means we have no simple and reliable way to continue.
17810 Break out the floating-point parsing into a new
17811 function string_to_number, so that Fstring_to_number parses
17812 floating point numbers consistently with the Lisp reader.
17813 (digit_to_number): Move here from data.c. Make it static inline.
17814 (E_CHAR, EXP_INT): Remove, replacing with ...
17815 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
17816 (string_to_number): New function, replacing isfloat_string.
17817 This function checks for valid syntax and produces the resulting
17818 Lisp float number too. Rework it so that string-to-number
17819 no longer mishandles examples like "1.0e+". Use strtoumax,
17820 so that overflow for non-base-10 numbers is reported only when
17821 there's no portable and simple way to convert to floating point.
17823 * textprop.c (set_text_properties_1): Rewrite for clarity,
17824 and to avoid GCC warning about integer overflow.
17826 * intervals.h (struct interval): Use EMACS_INT for members
17827 where EMACS_UINT might cause problems. See
17828 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
17829 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
17830 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
17832 (offset_intervals): Tell GCC not to worry about length overflow
17833 when negating a negative length.
17835 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
17836 (overrun_check_free): Likewise.
17838 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
17839 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
17842 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
17843 (gnutls_make_error): Rename local to avoid shadowing.
17844 (gnutls_emacs_global_deinit): ifdef out; not used.
17845 (Fgnutls_boot): Use const for pointer to readonly storage.
17846 Comment out unused local. Fix pointer signedness problems.
17848 * lread.c (openp): Don't stuff size_t into an 'int'.
17849 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
17850 about possible signed overflow.
17852 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
17853 (GDK_KEY_g): Don't define if already defined.
17854 (xg_prepare_tooltip): Avoid pointer signedness problem.
17855 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
17857 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
17858 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
17860 * xfns.c (Fx_window_property): Simplify a bit,
17861 to make a bit faster and to avoid GCC 4.6.0 warning.
17862 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
17864 * fns.c (internal_equal): Don't assume size_t fits in int.
17866 * alloc.c (compact_small_strings): Tighten assertion a little.
17868 Replace pEd with more-general pI, and fix some printf arg casts.
17869 * lisp.h (pI): New macro, generalizing old pEd macro to other
17870 conversion specifiers. For example, use "...%"pI"d..." rather
17871 than "...%"pEd"...".
17872 (pEd): Remove. All uses replaced with similar uses of pI.
17873 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
17874 * alloc.c (check_pure_size): Don't overflow by converting size to int.
17875 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
17876 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
17877 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
17878 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
17879 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
17881 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
17882 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
17883 * print.c (safe_debug_print, print_object): Likewise.
17884 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
17886 Use pI instead of if-then-else-abort. Use %p to avoid casts,
17887 avoiding the 0 flag, which is not portable.
17888 * process.c (Fmake_network_process): Use pI to avoid cast.
17889 * region-cache.c (pp_cache): Likewise.
17890 * xdisp.c (decode_mode_spec): Likewise.
17891 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
17892 behavior on 64-bit hosts with printf arg.
17893 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
17894 (x_stop_queuing_selection_requests): Likewise.
17895 (x_get_window_property): Don't truncate byte count to an 'int'
17898 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
17899 here, since it parses constructs like leading '-' and spaces,
17900 which are not wanted; and it overflows with large numbers.
17901 Instead, simply match F[0-9]+, which is what is wanted anyway.
17903 * alloc.c: Remove unportable assumptions about struct layout.
17904 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
17905 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
17906 (allocate_vectorlike, make_pure_vector): Use the new macros,
17907 plus offsetof, to remove unportable assumptions about struct layout.
17908 These assumptions hold on all porting targets that I know of, but
17909 they are not guaranteed, they're easy to remove, and removing them
17910 makes further changes easier.
17912 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
17913 This doesn't fix a bug but makes the code clearer.
17914 (string_overrun_cookie): Now const. Use initializers that
17915 don't formally overflow signed char, to avoid warnings.
17916 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
17917 can cause Emacs to crash when string overrun checking is enabled.
17918 (allocate_buffer): Don't assume sizeof (struct buffer) is a
17919 multiple of sizeof (EMACS_INT); it need not be, if
17920 alignof(EMACS_INT) < sizeof (EMACS_INT).
17921 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
17923 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

17930 supposed to be handshaking. (Bug#8556)
17931 Reported by Paul Eggert <eggert@cs.ucla.edu>.
17933 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
17935 * lisp.h (Qdebug): List symbol.
17936 * eval.c (Qdebug): Restore global linkage.

17950 2011-04-25 Eli Zaretskii <eliz@gnu.org>
17952 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
17953 "cast to pointer from integer of different size".
17955 Improve doprnt and its use in verror. (Bug#8545)
17956 * doprnt.c (doprnt): Document the set of format control sequences
17957 supported by the function. Use SAFE_ALLOCA instead of always
17960 * eval.c (verror): Don't limit the buffer size at size_max-1, that
17961 is one byte too soon. Don't use xrealloc; instead xfree and
17964 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
17966 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
17969 * gnutls.c: Renamed global_initialized to
17970 gnutls_global_initialized. Added internals for the
17971 :verify-hostname-error, :verify-error, and :verify-flags
17972 parameters of `gnutls-boot' and documented those parameters in the
17973 docstring. Start callback support.
17974 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
17975 unless a fatal error occurred. Call gnutls_alert_send_appropriate
17976 on error. Return error code.

18048 * doprnt.c: Include limits.h.
18049 (SIZE_MAX): New macro.
18050 (doprnt): Return a size_t value. 2nd arg is now size_t.
18051 Many local variables are now size_t instead of int or unsigned.
18052 Improve overflow protection. Support `l' modifier for integer
18053 conversions. Support %l conversion. Don't assume an EMACS_INT
18054 argument for integer conversions and for %c.
18056 * lisp.h (doprnt): Restore prototype.
18058 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
18059 $(SRC)/character.h.
18061 * Makefile.in (base_obj): Add back doprnt.o.
18063 * deps.mk (doprnt.o): Add back prerequisites.
18064 (callint.o): Depend on character.h.
18066 * eval.c (internal_lisp_condition_case): Include the handler
18067 representation in the error message.

18073 * callint.c (Fcall_interactively): When displaying error message
18074 about invalid control letter, pass the character's codepoint, not
18075 a pointer to its multibyte form. Improve display of the character
18076 in octal and display also its hex code.
18078 * character.c (char_string): Use %x to display the (unsigned)
18079 codepoint of an invalid character, to avoid displaying a bogus
18082 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
18083 `error', not SYMBOL_NAME itself.
18085 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
18086 character arguments to `error'.
18088 * charset.c (check_iso_charset_parameter): Fix incorrect argument
18089 to `error' in error message about FINAL_CHAR argument. Make sure
18090 FINAL_CHAR is a character, and use %c when it is passed as

18157 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
18158 by pacifying GCC about it. Maybe it's time to retire it?
18159 * xfaces.c (USG, __TIMEVAL__): Likewise.
18161 * dispextern.h (struct redisplay_interface): Rename param
18162 to avoid shadowing.
18163 * termhooks.h (struct terminal): Likewise.
18164 * xterm.c (xembed_send_message): Likewise.
18166 * insdel.c (make_gap_smaller): Define only if
18167 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
18169 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
18172 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
18173 so that we aren't warned about unused symbols.
18175 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
18177 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).

18190 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
18192 * xmenu.c (menu_help_callback): Pointer type fixes.

18210 compatible char. Avoid the old compiler warnings about
18211 out-of-range initializers by using, for example, '\xab' rather
18214 * xgselect.c (xgselect_initialize): Check vs interface
18215 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).

18280 * nsfont.m: Fixed bugs in ns_get_family and
18281 ns_descriptor_to_entity that were caused by using free to
18282 deallocate memory blocks that were allocated by xmalloc (via
18283 xstrdup). This caused Emacs to crash when compiled with
18284 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
18285 --enable-checking=xmallocoverrun). xfree is now used to
18286 deallocate these memory blocks.

18682 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
18683 * xmenu.c, xselect.c:
18684 Declare Q* vars static if they are not used in other modules.
18685 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
18686 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
18687 Remove decls of unexported vars.
18688 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
18690 * lisp.h (DEFINE_FUNC): Make sname 'static'.
18692 Make Emacs functions such as Fatom 'static' by default.
18693 This makes it easier for human readers (and static analyzers)
18694 to see whether these functions can be called from other modules.
18695 DEFUN now defines a static function. To make the function external
18696 so that it can be used in other C modules, use the new macro DEFUE.
18697 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
18698 (Finit_image_library):
18699 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
18700 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
18701 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
18702 Remove decls, since these functions are now static.
18703 (Funintern, Fget_internal_run_time): New decls, since these functions
18704 were already external.
18706 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
18707 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

18713 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
18714 Mark functions with DEFUE instead of DEFUN,
18715 if they are used in other modules.
18716 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
18717 decls for now-static functions.
18718 * buffer.h (Fdelete_overlay): Remove decl.
18719 * callproc.c (Fgetenv_internal): Mark as internal.
18720 * composite.c (Fremove_list_of_text_properties): Remove decl.

18724 * doc.c (Fdocumntation_property): New forward static decl.
18725 * eval.c (Ffetch_bytecode): New forward static decl.
18726 (Funintern): Remove extern decl; now in .h file where it belongs.
18727 * fileio.c (Fmake_symbolic_link): New forward static decl.
18728 * image.c (Finit_image_library): New forward static decl.
18729 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
18730 * intervals.h (Fprevious_property_change):
18731 (Fremove_list_of_text_properties): Remove decls.
18732 * keyboard.c (Fthis_command_keys): Remove decl.
18733 (Fcommand_execute): New forward static decl.
18734 * keymap.c (Flookup_key): New forward static decl.
18735 (Fcopy_keymap): Now static.
18736 * keymap.h (Flookup_key): Remove decl.

18749 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
18751 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
18754 2011-04-13 Eli Zaretskii <eliz@gnu.org>
18756 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
18757 when at ZV. (Bug#8487)
18759 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
18761 * charset.c (Fclear_charset_maps): Use xfree instead of free.
18763 * keyboard.c (parse_tool_bar_item): Likewise.
18764 * sound.c (sound_cleanup, alsa_close): Likewise.
18765 * termcap.c (tgetent): Likewise.
18766 * xfns.c (x_default_font_parameter): Likewise.
18767 * xsettings.c (read_and_apply_settings): Likewise.
18769 * alloc.c (overrun_check_malloc, overrun_check_realloc)
18770 (overrun_check_free): Protoize.
18772 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
18774 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
18775 since callers should never pass a negative size.
18776 Change the signature to match that of plain 'read' and 'write'; see
18777 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
18778 * lisp.h: Update prototypes of emacs_write and emacs_read.
18780 2011-04-11 Eli Zaretskii <eliz@gnu.org>
18782 * xdisp.c (redisplay_window): Don't try to determine the character
18783 position of the scroll margin if the window start point w->startp
18784 is outside the buffer's accessible region. (Bug#8468)
18786 2011-04-10 Eli Zaretskii <eliz@gnu.org>
18788 Fix write-region and its subroutines for buffers > 2GB.
18789 * fileio.c (a_write, e_write): Modify declaration of arguments and
18790 local variables to support buffers larger than 2GB.
18791 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
18793 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
18794 argument, local variables, and return value.
18796 * lisp.h: Update prototypes of emacs_write and emacs_read.
18798 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
18800 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
18802 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
18804 Fix more problems found by GCC 4.6.0's static checks.
18806 * xdisp.c (vmessage): Use a better test for character truncation.
18808 * charset.c (load_charset_map): <, not <=, for optimization,
18809 and to avoid potential problems with integer overflow.
18810 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
18811 * casetab.c (set_identity, shuffle): Likewise.
18812 * editfns.c (Fformat): Likewise.
18813 * syntax.c (skip_chars): Likewise.
18815 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
18816 This also lets GCC 4.6.0 generate slightly better loop code.
18818 * callint.c (Fcall_interactively): <, not <=, for optimization.
18819 (Fcall_interactively): Count the number of arguments produced,
18820 not the number of arguments given. This is simpler and lets GCC
18821 4.6.0 generate slightly better code.
18823 * ftfont.c: Distingish more carefully between FcChar8 and char.
18824 The previous code passed unsigned char * to a functions like
18825 strlen and xstrcasecmp that expect char *, which does not
18826 conform to the C standard.
18827 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
18828 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
18829 char * when the C standard requires it.
18831 * keyboard.c (read_char): Remove unused var.
18833 * eval.c: Port to Windows vsnprintf (Bug#8435).
18834 Include <limits.h>.
18835 (SIZE_MAX): Define if the headers do not.
18836 (verror): Do not give up if vsnprintf returns a negative count.
18837 Instead, grow the buffer. This ports to Windows vsnprintf, which
18838 does not conform to C99. Problem reported by Eli Zaretskii.
18839 Also, simplify the allocation scheme, by avoiding the need for
18840 calling realloc, and removing the ALLOCATED variable.
18842 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
18844 Remove invocations of doprnt, as Emacs now uses vsnprintf.
18845 But keep the doprint source code for now, as we might revamp it
18846 and use it again (Bug#8435).
18847 * lisp.h (doprnt): Remove.
18848 * Makefile.in (base_obj): Remove doprnt.o.
18849 * deps.mk (doprnt.o): Remove.
18851 error: Print 32- and 64-bit integers portably (Bug#8435).
18852 Without this change, on typical 64-bit hosts error ("...%d...", N)
18853 was used to print both 32- and 64-bit integers N, which relied on
18854 undefined behavior.
18855 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
18856 * lisp.h (error, verror): Mark as printf-like functions.
18857 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
18858 Report overflow in size calculations when allocating printf buffer.
18859 Do not truncate output string at its first null byte.
18860 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
18861 Truncate the output at a character boundary, since vsnprintf does not
18863 * charset.c (check_iso_charset_parameter): Convert internal
18864 character to string before calling 'error', since %c now has the
18866 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
18867 overflow when computing char to be passed to 'error'. Do not
18868 pass Lisp_Object to 'error'; pass the integer instead.
18869 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
18870 formatted with plain %d.
18872 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
18874 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
18876 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
18878 * xterm.c (x_catch_errors): Remove duplicate declaration.
18880 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
18882 * xdisp.c, lisp.h (message_nolog): Remove; unused.
18884 2011-04-10 Jim Meyering <meyering@redhat.com>
18886 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
18887 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
18888 return ssize_t not "int", and use size_t as the buffer length.
18889 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
18890 * gnutls.h: Update declarations.
18891 * process.c (read_process_output): Use ssize_t, to match.
18892 (send_process): Likewise.
18894 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
18896 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
18898 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
18900 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
18901 Use unsigned char, to match FcChar8 type definition.
18903 * xterm.c (handle_one_xevent):
18904 * xmenu.c (create_and_show_popup_menu):
18905 * xselect.c (x_decline_selection_request)
18906 (x_reply_selection_request): Avoid type-punned deref of X events.
18908 2011-04-09 Eli Zaretskii <eliz@gnu.org>
18910 Fix some uses of `int' instead of EMACS_INT.
18911 * search.c (string_match_1, fast_string_match)
18912 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
18913 (scan_buffer, find_next_newline_no_quit)
18914 (find_before_next_newline, search_command, Freplace_match)
18915 (Fmatch_data): Make some `int' variables be EMACS_INT.
18917 * xdisp.c (display_count_lines): 3rd argument and return value now
18918 EMACS_INT. All callers changed.
18919 (pint2hrstr): Last argument is now EMACS_INT.
18921 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
18922 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
18923 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
18924 (decode_coding_utf_16, decode_coding_emacs_mule)

18926 (decode_coding_ccl, decode_coding_charset)
18927 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
18928 (decode_coding_iso_2022, decode_coding_emacs_mule)
18929 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
18930 <char_offset, last_offset>: Declare EMACS_INT.

18933 (encode_designation_at_bol, encode_coding_iso_2022)
18934 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
18935 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
18937 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
18938 (encode_invocation_designation): Last argument P_NCHARS is now
18940 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
18941 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
18943 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
18946 * ccl.c (Fccl_execute_on_string): Declare some variables
18949 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
18951 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
18953 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
18955 * process.c (Fformat_network_address): Doc fix.
18957 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
18959 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
18961 2011-04-08 Chong Yidong <cyd@stupidchicken.com>

18964 instead of using internal_with_output_to_temp_buffer.
18965 (Qhelp_form_show): New var.
18966 (syms_of_keyboard): Use DEFSYM macro.
18968 * print.c (internal_with_output_to_temp_buffer): Function deleted.

18979 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
18981 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
18983 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
18985 Fix more problems found by GCC 4.6.0's static checks.
18987 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
18989 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
18991 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
18993 * xdisp.c (vmessage): Mark as a printf-like function.
18995 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
18997 * sound.c (sound_warning): Don't crash if arg contains a printf format.

19002 to system-supplied API.
19004 * eval.c (Fsignal): Remove excess argument to 'fatal'.
19006 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
19007 This avoids several warnings with gcc -Wstrict-overflow.
19008 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
19009 directly, rather than having caller test rule sign. This avoids
19010 some unnecessary tests.
19011 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
19012 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
19013 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
19015 * xfont.c (xfont_text_extents): Remove var that was set but not used.
19016 (xfont_open): Avoid unnecessary tests.
19018 * composite.c (composition_gstring_put_cache): Use unsigned integer.

19027 by using the new macro.
19029 * textprop.c (set_text_properties_1): Change while to do-while,
19030 since the condition is always true at first.
19032 * intervals.c (graft_intervals_into_buffer): Mark var as used.
19033 (interval_deletion_adjustment): Return unsigned value.
19036 * process.c (list_processes_1, create_pty, read_process_output):

19049 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
19050 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
19052 * print.c (print_error_message): Avoid int overflow.
19054 * font.c (font_list_entities): Redo for clarity,
19055 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
19057 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
19058 (font_score): Avoid potential overflow in diff calculation.
19060 * fns.c (substring_both): Remove var that is set but not used.
19061 (sxhash): Redo loop for clarity and to avoid wraparound warning.
19063 * eval.c (funcall_lambda): Rename local to avoid shadowing.
19065 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
19066 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
19067 can always succeed if overflow has undefined behavior.
19069 * search.c (boyer_moore, wordify): Remove vars set but not used.
19070 (wordify): Omit three unnecessary tests.
19072 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
19073 All callers changed. This avoids the need for an unused var.
19075 * casefiddle.c (casify_region): Remove var that is set but not used.
19077 * dired.c (file_name_completion): Remove var that is set but not used.

19081 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
19082 (Finsert_file_contents): Remove unnecessary code checking fd.
19084 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
19085 Check for integer overflow on size calculations.
19087 * buffer.c (Fprevious_overlay_change): Remove var that is set
19090 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
19091 Remove vars that are set but not used.
19092 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
19093 (timer_check_2): Mark vars as initialized.
19095 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
19097 * image.c (lookup_image): Remove var that is set but not used.
19098 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
19100 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
19101 that are set but not used.
19103 * xfns.c (make_invisible_cursor): Don't return garbage
19104 if XCreateBitmapFromData fails (Bug#8410).
19106 * xselect.c (x_get_local_selection, x_handle_property_notify):
19107 Remove vars that are set but not used.
19109 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
19110 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
19112 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
19113 Remove var that is set but not used.
19114 (scroll_bar_windows_size): Now size_t, not int.
19115 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
19116 Check for overflow.
19118 * xfaces.c (realize_named_face): Remove vars that are set but not used.
19119 (map_tty_color) [!defined MSDOS]: Likewise.
19121 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
19123 * coding.c: Remove vars that are set but not used.
19124 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.

19131 that is set but not used.
19133 * print.c (print_object): Remove var that is set but not used.
19135 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
19136 The gnulib version avoids calling malloc in the usual case,
19137 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
19138 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
19139 * filelock.c (current_lock_owner): Likewise.
19140 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
19141 * sysdep.c: Include allocator.h, careadlinkat.h.
19142 (emacs_no_realloc_allocator): New static constant.
19143 (emacs_readlink): New function.
19144 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
19145 ../lib/careadlinkat.h.
19147 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
19149 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the

19171 do not dereference NULL upon failed strdup
19172 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
19173 (ns_get_family): Likewise.
19175 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
19177 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
19179 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
19181 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
19184 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
19186 Add lexical binding.
19188 * window.c (Ftemp_output_buffer_show): New fun.

19197 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
19199 (syms_of_lread): Declare `lexical-binding'.
19201 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
19203 * keyboard.c (eval_dyn): New fun.
19204 (menu_item_eval_property): Use it.
19206 * image.c (parse_image_spec): Use Ffunctionp.
19208 * fns.c (concat, mapcar1): Accept byte-code-functions.
19210 * eval.c (Fsetq): Handle lexical vars.
19211 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
19212 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
19213 (FletX, Flet): Obey lexical binding.
19214 (Fcommandp): Handle closures.
19215 (Feval): New `lexical' arg.
19216 (eval_sub): New function extracted from Feval. Use it almost
19217 everywhere where Feval was used. Look up vars in lexical env.
19219 (Ffunctionp): Move from subr.el.
19220 (Ffuncall): Handle closures.
19221 (apply_lambda): Remove `eval_flags'.
19222 (funcall_lambda): Handle closures and new byte-code-functions.
19223 (Fspecial_variable_p): New function.
19224 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
19225 but without exporting it to Lisp.
19227 * doc.c (Fdocumentation, store_function_docstring):
19228 * data.c (Finteractive_form): Handle closures.
19230 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
19233 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
19235 (exec_byte_code): New function extracted from Fbyte_code to handle new
19236 calling convention for byte-code-functions. Add new byte-codes.
19238 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
19240 * alloc.c (Fmake_symbol): Init new `declared_special' field.
19242 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
19244 * xdisp.c (redisplay_internal): Fix prototype.
19246 2011-03-31 Eli Zaretskii <eliz@gnu.org>
19248 * xdisp.c (SCROLL_LIMIT): New macro.
19249 (try_scrolling): Use it when setting scroll_limit.
19250 Limit scrolling to 100 screen lines.
19251 (redisplay_window): Even when falling back on "recentering",
19252 position point in the window according to scroll-conservatively,
19253 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
19255 (try_scrolling): When point is above the window, allow searching
19256 as far as scroll_max, or one screenful, to compute vertical
19257 distance from PT to the scroll margin position. This prevents
19258 try_scrolling from unnecessarily failing when
19259 scroll-conservatively is set to a value slightly larger than the
19260 window height. Clean up the case of PT below the margin at bottom
19261 of window: scroll_max can no longer be INT_MAX. When aggressive
19262 scrolling is in use, don't let point enter the opposite scroll
19263 margin as result of the scroll.
19264 (syms_of_xdisp) <scroll-conservatively>: Document the
19265 threshold of 100 lines for never-recentering scrolling.

19272 (message_log_check_duplicate): Remove parameters `prev_bol' and
19273 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
19274 (redisplay_internal): Remove parameter `preserve_echo_area',
19275 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
19277 * indent.c (Fvertical_motion):
19278 * window.c (window_scroll_pixel_based, Frecenter):
19279 Don't pass `need_y_p' to `move_it_by_lines'.
19281 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
19283 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
19284 steal a few bits to be more compact.
19285 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
19286 Remove unneeded casts.
19288 * bytecode.c (Fbyte_code): CAR and CDR can GC.
19290 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
19292 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
19293 binding" message (bug#7967).
19295 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
19297 Fix more problems found by GCC 4.6.0's static checks.
19299 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
19300 Remove unused local var.
19302 * editfns.c (Fmessage_box): Remove unused local var.
19304 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
19305 (note_mode_line_or_margin_highlight, note_mouse_highlight):
19306 Omit unused local vars.
19307 * window.c (shrink_windows): Omit unused local var.
19308 * menu.c (digest_single_submenu): Omit unused local var.
19309 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
19310 Omit unused local var.
19312 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
19313 Don't assume string length fits in int.
19314 (keyremap_step, read_key_sequence): Use size_t for sizes.

19317 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
19318 instead of alloca (Bug#8344).
19320 * eval.c (Fbacktrace): Don't assume nargs fits in int.
19321 (Fbacktrace_frame): Don't assume nframes fits in int.
19323 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

19330 * cm.c (calccost): Turn while-do into do-while, for clarity.
19332 * keyboard.c (syms_of_keyboard): Use the same style as later
19333 in this function when indexing through an array. This also
19334 works around GCC bug 48267.
19336 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
19338 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
19340 * chartab.c (sub_char_table_ref_and_range): Redo for slight
19341 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
19343 * keyboard.c, keyboard.h (num_input_events): Now size_t.
19344 This avoids undefined behavior on integer overflow, and is a bit
19345 more convenient anyway since it is compared to a size_t variable.
19347 Variadic C functions now count arguments with size_t, not int.
19348 This avoids an unnecessary limitation on 64-bit machines, which
19349 caused (substring ...) to crash on large vectors (Bug#8344).

19359 * fns.c (concat): Likewise.
19360 * frame.c (x_set_frame_parameters): Likewise.
19361 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
19362 0 if not found, not -1. All callers changed.
19364 * alloc.c (garbage_collect): Don't assume stack size fits in int.
19365 (stack_copy_size): Now size_t, not int.
19366 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
19368 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
19370 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
19371 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

19387 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
19388 don't set the hook to nil, but remove the offending function instead.
19389 (Qcommand_hook_internal): Remove, unused.
19390 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
19391 Vcommand_hook_internal.
19393 * eval.c (enum run_hooks_condition): Remove.
19394 (funcall_nil, funcall_not): New functions.
19395 (run_hook_with_args): Call each function through a `funcall' argument.

19559 2011-03-23 Julien Danjou <julien@danjou.info>
19561 * term.c (Fsuspend_tty, Fresume_tty):
19562 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
19563 * window.c (temp_output_buffer_show):
19564 * insdel.c (signal_before_change):
19565 * frame.c (Fhandle_switch_frame):
19566 * fileio.c (Fdo_auto_save):
19567 * emacs.c (Fkill_emacs):
19568 * editfns.c (save_excursion_restore):
19569 * cmds.c (internal_self_insert):
19570 * callint.c (Fcall_interactively):
19571 * buffer.c (Fkill_all_local_variables):
19572 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
19574 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
19575 unconditionally since it does the check itself.
19577 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
19579 Fix more problems found by GCC 4.5.2's static checks.
19581 * coding.c (encode_coding_raw_text): Avoid unnecessary test
19582 the first time through the loop, since we know p0 < p1 then.
19583 This also avoids a gcc -Wstrict-overflow warning.
19585 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
19586 leading to a memory leak, possible in functions like
19587 load_charset_map_from_file that can allocate an unbounded number
19588 of objects (Bug#8318).
19590 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
19591 that could (at least in theory) be that large.
19593 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
19594 This is less likely to overflow, and avoids undefined behavior if
19595 overflow does occur. All callers changed. Use strtoul to scan
19596 for the unsigned long integer.
19597 (pint2hrstr): Simplify and tune code slightly.
19598 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
19600 * scroll.c (do_scrolling): Work around GCC bug 48228.
19601 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
19603 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
19604 This also avoids a warning with gcc -Wstrict-overflow.
19605 (validate_x_resource_name): Simplify count usage.
19606 This also avoids a warning with gcc -Wstrict-overflow.
19608 * fileio.c (Fcopy_file): Report error if fchown or fchmod
19611 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
19613 * process.c (Fmake_network_process): Use socklen_t, not int,
19614 where POSIX says socklen_t is required in portable programs.
19615 This fixes a porting bug on hosts like 64-bit HP-UX, where
19616 socklen_t is wider than int (Bug#8277).
19617 (Fmake_network_process, server_accept_connection):
19618 (wait_reading_process_output, read_process_output):
19621 * process.c: Rename or move locals to avoid shadowing.
19622 (list_processes_1, Fmake_network_process):
19623 (read_process_output_error_handler, exec_sentinel_error_handler):
19624 Rename or move locals.
19625 (Fmake_network_process): Define label "retry_connect" only if needed.
19626 (Fnetwork_interface_info): Fix pointer signedness.
19627 (process_send_signal): Add cast to avoid pointer signedness problem.
19628 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
19629 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
19631 Make tparam.h and terminfo.c consistent.
19632 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
19633 Include tparam.h instead, since it declares them.
19634 * cm.h (PC): Remove extern decl; tparam.h now does this.
19635 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
19636 * terminfo.c: Include tparam.h, to check interfaces.
19637 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
19638 (tparam): Adjust signature to match interface in tparam.h;
19639 this removes some undefined behavior. Check that outstring and len
19640 are zero, which they always are with Emacs.
19641 * tparam.h (PC, BC, UP): New extern decls.
19643 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
19644 (xftfont_open): Rename locals to avoid shadowing.
19646 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
19647 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
19648 (OTF_TAG_SYM): Omit macro if not needed.
19649 (ftfont_list): Remove unused local.
19650 (get_adstyle_property, ftfont_pattern_entity):
19651 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
19652 Rename locals to avoid shadowing.
19654 * xfont.c (xfont_list_family): Mark var as initialized.
19656 * xml.c (make_dom): Now static.
19658 * composite.c (composition_compute_stop_pos): Rename local to
19660 (composition_reseat_it): Remove unused locals.
19661 (find_automatic_composition, composition_adjust_point): Likewise.
19662 (composition_update_it): Mark var as initialized.
19663 (find_automatic_composition): Mark vars as initialized,
19664 with a FIXME (Bug#8290).
19666 character.h: Rename locals to avoid shadowing.
19667 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
19668 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
19669 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
19670 (BUF_DEC_POS): Be more systematic about renaming local temporaries
19671 to avoid shadowing.
19673 * textprop.c (property_change_between_p): Remove; unused.
19675 * intervals.c (interval_start_pos): Now static.
19677 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

19680 Rename locals to avoid shadowing.
19682 * sound.c (wav_play, au_play, Fplay_sound_internal):
19683 Fix pointer signedness.
19684 (alsa_choose_format): Remove unused local var.
19685 (wav_play): Initialize a variable to 0, to prevent undefined
19686 behavior (Bug#8278).
19688 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
19690 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
19692 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
19693 clobbering (Bug#8298).
19694 * sysdep.c (sys_subshell): Likewise.
19695 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
19697 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
19698 This should get cleaned up, so that child_setup has the
19699 same signature on all platforms.
19701 * callproc.c (call_process_cleanup): Now static.
19702 (relocate_fd): Rename locals to avoid shadowing.
19704 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
19706 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
19707 not to be necessary, and produces flickering.
19709 2011-03-20 Glenn Morris <rgm@gnu.org>
19711 * config.in: Remove file.
19713 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
19715 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
19716 are now in src/globals.h.
19717 (syms_of_minibuf): Remove spurious & from previous change.
19719 2011-03-20 Leo Liu <sdl.web@gmail.com>
19721 * minibuf.c (completing-read-function): New variable.
19722 (completing-read-default): Rename from completing-read.
19723 (completing-read): Call completing-read-function.
19725 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
19727 * xfaces.c (Fx_load_color_file):
19728 Read color file from absolute filename (bug#8250).
19730 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
19732 * makefile.w32-in: Update dependencies.
19734 2011-03-17 Eli Zaretskii <eliz@gnu.org>
19736 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.
19738 2011-03-17 Paul Eggert <eggert@cs.ucla.edu>

19743 (sigchld_handler): Now static.
19745 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
19746 That way, the code declares only the vars that it needs.
19747 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
19748 * s/cygwin.h (PTY_ITERATION): Likewise.
19749 * s/darwin.h (PTY_ITERATION): Likewise.

19753 * process.c (allocate_pty): Don't declare stb unless it's needed.
19755 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
19756 (CONSTANTLIM): Remove; unused.
19757 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
19758 Define only if needed.
19760 * unexelf.c (unexec): Name an expression,
19761 to avoid gcc -Wbad-function-cast warning.
19762 Use a different way to cause a compilation error if anyone uses
19763 n rather than nn, a way that does not involve shadowing.
19764 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
19766 * deps.mk (unexalpha.o): Remove; unused.
19768 New file unexec.h, the (simple) interface for unexec (Bug#8267).
19769 * unexec.h: New file.
19770 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
19771 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
19772 Depend on unexec.h.
19773 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
19774 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
19775 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
19776 Change as necessary to match prototype in unexec.h.
19778 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid
19780 (back_comment, skip_chars): Mark vars as initialized.

19794 instead of using an uninitialized var.
19795 (font_sort_entities): Mark var as initialized.
19797 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
19799 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

19811 * floatfns.c (domain_error2): Define only if needed.
19812 (Ffrexp, Fldexp): Rename locals to avoid shadowing.
19814 * alloc.c (mark_backtrace): Move decl from here ...

19823 * callint.c (quotify_arg, quotify_args): Now static.
19824 (Fcall_interactively): Rename locals to avoid shadowing.
19825 Use const pointer when appropriate.

19831 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
19832 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
19833 some of which prompt warnings from gcc -Wbad-function-cast.
19834 (Fformat_time_string, Fencode_time, Finsert_char):
19835 (Ftranslate_region_internal, Fformat):
19836 Rename or remove local vars to avoid shadowing.
19837 (Ftranslate_region_internal): Mark var as initialized.
19839 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
19842 * lisp.h (eassert): Check that the argument compiles, even if
19843 ENABLE_CHECKING is not defined.
19845 * data.c (Findirect_variable): Name an expression, to avoid
19846 gcc -Wbad-function-cast warning.
19847 (default_value, arithcompare, arith_driver, arith_error): Now static.

19855 Rename locals to avoid shadowing.
19856 (mark_stack): Move local variables into the #ifdef region where
19858 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
19859 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
19861 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
19862 (GC_STRING_CHARS): Remove; not used.
19863 (Fmemory_limit): Cast sbrk's returned value to char *.
19865 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
19866 avoids undefined behavior in theory.
19868 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
19870 Use functions, not macros, for up- and down-casing (Bug#8254).
19871 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
19872 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
19873 to use the following functions instead of these macros.
19874 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
19875 EMACS_INT, since callers assume the returned value fits in int.
19876 (upcase1): Likewise, for UPCASE_TABLE.
19877 (uppercasep, lowercasep, upcase): New static inline functions.
19878 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
19879 the race-condition problem in the old DOWNCASE.
19881 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
19882 Rename locals to avoid shadowing.
19883 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
19884 (regex_compile, re_search_2, re_match_2_internal):
19885 Remove unused local vars.
19886 (FREE_VAR): Rewrite so as not to use empty "else",
19887 which gcc can warn about.
19888 (regex_compile, re_match_2_internal): Mark locals as initialized.
19889 (RETALLOC_IF): Define only if needed.
19890 (WORDCHAR_P): Likewise. This one is never needed, but is used
19891 only in a comment talking about a compiler bug, so put inside
19892 the #if 0 of that comment.
19893 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
19894 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
19897 * search.c (boyer_moore): Rename locals to avoid shadowing.
19898 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
19899 (PREV_CHAR_BOUNDARY): Likewise.

19909 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
19911 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
19912 Rename locals to avoid shadowing.
19913 (Fvertical_motion): Mark locals as initialized.
19915 * casefiddle.c (casify_object, casify_region): Now static.
19916 (casify_region): Mark local as initialized.
19918 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
19920 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
19921 New macros, so that the caller can use some names other than
19922 gcpro1, gcpro2, etc.
19923 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
19925 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
19926 argument, for consistency with GCPRO2_VAR, etc: it is now the
19927 prefix of the variable, not the variable itself. All uses
19929 * dired.c (directory_files_internal, file_name_completion):
19930 Rename locals to avoid shadowing.
19932 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
19933 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
19934 dired.c's scmp function, had undefined behavior.
19935 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
19936 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
19937 * buffer.h: ... to here, because these macros use current_buffer,
19938 and the new implementation with inline functions needs to have
19939 current_buffer in scope now, rather than later when the macros
19941 (downcase, upcase1): New static inline functions.
19942 (DOWNCASE, UPCASE1): Reimplement using these functions.
19943 This avoids undefined behavior in expressions like
19944 DOWNCASE (x) == DOWNCASE (y), which previously suffered
19945 from race conditions in accessing the global variables
19946 case_temp1 and case_temp2.
19947 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
19948 * lisp.h (case_temp1, case_temp2): Remove their decls.
19949 * character.h (ASCII_CHAR_P): Move from here ...
19950 * lisp.h: ... to here, so that the inline functions mentioned
19951 above can use them.
19953 * dired.c (directory_files_internal_unwind): Now static.
19955 * fileio.c (file_name_as_directory, directory_file_name):
19956 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
19958 (file_name_as_directory): Use const pointers when appropriate.
19959 (Fexpand_file_name): Likewise. In particular, newdir might
19960 point at constant storage, so make it a const pointer.
19961 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
19962 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
19964 (Fset_file_times, Finsert_file_contents, auto_save_error):
19965 Rename locals to avoid shadowing.
19967 * minibuf.c (choose_minibuf_frame_1): Now static.
19968 (Ftry_completion, Fall_completions): Rename or remove locals
19969 to avoid shadowing.
19971 * marker.c (bytepos_to_charpos): Remove; unused.
19973 * lisp.h (verify_bytepos, count_markers): New decls,
19974 so that gcc does not warn that these functions aren't declared.
19976 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
19977 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
19978 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
19979 (copy_text): Remove unused local var.
19981 * filelock.c (within_one_second): Now static.
19982 (lock_file_1): Rename local to avoid shadowing.
19984 * buffer.c (fix_overlays_before): Mark locals as initialized.
19985 (fix_start_end_in_overlays): Likewise. This function should be
19986 simplified by using pointers-to-pointers, but that's a different
19988 (switch_to_buffer_1): Now static.
19989 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
19990 (report_overlay_modification): Rename locals to avoid shadowing.
19992 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
19993 Fix pointer signedness issue.
19994 (sys_subshell): Mark local as volatile if checking for lint,
19995 to suppress a gcc -Wclobbered warning that does not seem to be right.
19996 (MAXPATHLEN): Define only if needed.
19998 * process.c (serial_open, serial_configure): Move decls from here ...
19999 * systty.h: ... to here, so that they can be checked.
20001 * fns.c (get_random, seed_random): Move extern decls from here ...
20002 * lisp.h: ... to here, so that they can be checked.
20004 * sysdep.c (reset_io): Now static.
20005 (wait_for_termination_signal): Remove; unused.
20007 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
20008 (copy_keymap_item, append_key, push_text_char_description):
