3 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
4 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
5 and mouse_face_hidden members to a bitfields.
6 * frame.h (struct frame): Remove set-but-not-used space_width member.
7 (FRAME_SPACE_WIDTH): Remove.

16 Don't let call-process be a zombie factory (Bug#12980).
17 Fixing this bug required some cleanup of the signal-handling code.
18 As a side effect, this change also fixes a longstanding rare race
19 condition whereby Emacs could mistakenly kill unrelated processes,
20 and it fixes a bug where a second C-g does not kill a recalcitrant
21 synchronous process in GNU/Linux and similar platforms.
22 The patch should also fix the last vestiges of Bug#9488,
23 a bug which has mostly been fixed on the trunk by other changes.
24 * callproc.c, process.h (synch_process_alive, synch_process_death)
25 (synch_process_termsig, sync_process_retcode):
26 Remove. All uses removed, to simplify analysis and so that
27 less consing is done inside critical sections.
28 * callproc.c (call_process_exited): Remove. All uses replaced
29 with !synch_process_pid.
30 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
31 These take the role of what used to be in unwind-protect arg.
33 (block_child_signal, unblock_child_signal):
34 New functions, to avoid races that could kill innocent-victim processes.
35 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
36 (call_process_kill): Record killed processes as deleted, so that
37 zombies do not clutter up the system. Do this inside a critical
38 section, to avoid a race that would allow the clutter.
39 (call_process_cleanup): Fix code so that the second C-g works again
40 on common platforms such as GNU/Linux.
41 (Fcall_process): Create the child process in a critical section,
42 to fix a race condition. If creating an asynchronous process,
43 record it as deleted so that zombies do not clutter up the system.
44 Do unwind-protect for WINDOWSNT too, as that's simpler in the
45 light of these changes. Omit unnecessary call to emacs_close
46 before failure, as the unwind-protect code does that.
47 * callproc.c (call_process_cleanup):
48 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
49 * process.c (record_deleted_pid): New function, containing
50 code refactored out of Fdelete_process.
51 (Fdelete_process): Use it.
52 (process_status_retrieved): Remove. All callers changed to use
54 (record_child_status_change): Remove, folding its contents into ...
55 (handle_child_signal): ... this signal handler. Now, this
56 function is purely a handler for SIGCHLD, and is not called after
57 a synchronous waitpid returns; the synchronous code is moved to
58 wait_for_termination. There is no need to worry about reaping
59 more than one child now.
60 * sysdep.c (get_child_status, child_status_changed): New functions.
61 (wait_for_termination): Now takes int * status and bool
62 interruptible arguments, too. Do not record child status change;
63 that's now the caller's responsibility. All callers changed.
64 Reimplement in terms of get_child_status.
65 (wait_for_termination_1, interruptible_wait_for_termination):
66 Remove. All callers changed to use wait_for_termination.
67 * syswait.h: Include <stdbool.h>, for bool.
68 (record_child_status_change, interruptible_wait_for_termination):
70 (record_deleted_pid, child_status_changed): New decls.
71 (wait_for_termination): Adjust to API changes noted above.
73 * bytecode.c, lisp.h (Qbytecode): Remove.
74 No longer needed after 2012-11-20 interactive-p changes.
76 2012-12-03 Eli Zaretskii <eliz@gnu.org>
78 * xdisp.c (redisplay_window): If the cursor is visible, but inside
79 the scroll margin, move point outside the margin. (Bug#13055)
81 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
83 * gtkutil.c (my_log_handler): New function.
84 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).

88 * lisp.h (modify_region): Rename to...
89 (modify_region_1): ...new prototype.
90 * textprop.c (modify_region): Now static. Adjust users.
91 * insdel.c (modify_region): Rename to...
92 (modify_region_1): ...new function to work with current buffer.
93 Adjust comment and users. Use true and false for booleans.
95 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
97 * alloc.c (free_save_value): New function.
98 (safe_alloca_unwind): Use it.
99 * lisp.h (free_save_value): New prototype.
100 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
102 (save_excursion_restore): Adjust to match saved data structure.
103 Use free_save_value to offload some work from GC. Drop obsolete
106 2012-12-03 Chong Yidong <cyd@gnu.org>
108 * fileio.c (Vauto_save_list_file_name): Doc fix.
110 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
112 * w32fns.c: Remove prototype of atof.
113 (syspage_mask): Declared DWORD_PTR, for compatibility with 64-bit
115 (file_dialog_callback): Declared UINT_PTR.
117 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
120 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
121 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
124 2012-12-03 Glenn Morris <rgm@gnu.org>
126 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
128 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
130 Fix xpalloc confusion after memory is exhausted.
131 * alloc.c (xpalloc): Comment fix.
132 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
133 and signals an error, do not clear charset_table_size, as
134 charset_table is still valid.
135 * doprnt.c (evxprintf): Clear *BUF after freeing it.
137 Use execve to avoid need to munge environ (Bug#13054).
138 * callproc.c (Fcall_process):
139 * process.c (create_process):
140 Don't save and restore environ; no longer needed.
141 * callproc.c (child_setup):
142 Use execve, not execvp, to preserve environ.
144 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
146 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
148 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
150 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
151 display for sliced images (Bug#10500).
153 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
155 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
157 * doc.c (Fdocumentation): Re-add handling of function-documentation,
158 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
160 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
162 * xdisp.c (window_outdated): Remove eassert since it hits
163 some suspicious corner cases (see Bug#13007 and Bug#13012).
164 (mode_line_update_needed): New function.
165 (redisplay_internal, redisplay_window): Use it.
166 (ensure_selected_frame): New function.
167 (redisplay_internal, unwind_redisplay): Use it.
168 (redisplay_internal): Move comment about buffer_shared...
169 (buffer_shared_and_changed): ...near to its real use.
171 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
173 * callproc.c (Fcall_process): Don't misreport vfork failure.
175 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
177 * callproc.c (Fcall_process): Fix vfork portability problems.
178 Do not assume that fd[0], count, filefd, and save_environ survive
179 vfork. Fix bug whereby wrong errno value could be reported for
180 pipe failure. Some minor cleanups, too, as follows. Move buf and
181 bufsize to the context where they're needed. Change new_argv to
182 be of type char **, as this is more convenient and avoids casts.
183 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
184 Now local constants, not macros.
186 2012-11-18 Kenichi Handa <handa@gnu.org>
188 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
189 for the variable "f".
191 2012-11-13 Kenichi Handa <handa@gnu.org>
193 * font.c (font_unparse_xlfd): Exclude special characters from the
194 generating XLFD name.

236 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
237 between bpos_covered and bpos_max. This fixes cursor display when
238 several display strings follow each other.
240 * .gdbinit (pgx): If the glyph's object is a string, display the
241 pointer to string data, rather than the value of the string object
242 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
244 * indent.c (Fvertical_motion): If the starting position is covered
245 by a display string, return to one position before that, to avoid
246 overshooting it inside move_it_to. (Bug#12930)
248 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
250 * frame.h (struct frame): Remove display_preempted member

259 unused pending_menu_activation member.
260 * xterm.h (struct x_output): Drop outdated #if 0 code.
261 Use bitfields for explicit_parent, asked_for_visible,
262 has_been_visible and net_wm_state_hidden_seen members.

267 of a literal "/". (Bug#12955)
268 (gl-stamp): Invoke fc.exe directly, not through cmd.
270 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>

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

287 2012-11-23 Chong Yidong <cyd@gnu.org>
289 * xftfont.c (xftfont_open): Remove duplicate assignment.
291 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
293 * alloc.c (Fgarbage_collect): Unblock input after clearing
294 gc_in_progress to avoid note_mouse_highlight glitch with GC.
295 * frame.h (FRAME_MOUSE_UPDATE): New macro.
296 * msdos.c (IT_frame_up_to_date): Use it here...
297 * w32term.c (w32_frame_up_to_date): ...here...
298 * xterm.c (XTframe_up_to_date): ...and here...
299 * nsterm.m (ns_frame_up_to_date): ...but not here.
300 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
302 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):

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

341 2012-11-21 Eli Zaretskii <eliz@gnu.org>
343 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
344 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
345 Define for the MSVC compiler.
347 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
349 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
350 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
351 dostounix_filename. Prevents crashes down the road, because
352 dostounix_filename assumes it gets a unibyte string. Reported by
353 Michel de Ruiter <michel@sentient.nl>, see
354 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
356 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>

380 (text_outside_line_unchanged_p, redisplay_window): Use it.
381 (redisplay_internal): Likewise. Fix indentation.
383 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>

392 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
393 cygwin_convert_file_name*.

396 Rename cygwin_convert_path* to cygwin_convert_file_name*.
398 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
400 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
402 2012-11-18 Eli Zaretskii <eliz@gnu.org>
404 * w32select.c: Include w32common.h before w32term.h, so that
405 windows.h gets included before w32term.h uses some of its
408 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
410 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:

421 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
422 Needed following 2012-10-20 change. (Bug#12902)
424 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
426 * w32proc.c (waitpid): Remove unused label get_result.
428 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
430 * makefile.w32-in (SYSWAIT_H): New macro.
431 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
432 ($(BLD)/sysdep.$(O)): Update dependencies.
434 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
436 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
437 * callproc.c (relocate_fd): Assume F_DUPFD.
438 * emacs.c, term.c (O_RDWR): Remove.
439 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
440 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
441 * nsterm.m: Assume <fcntl.h> exists.
442 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
443 (create_pty, Fmake_network_process, server_accept_connection)
444 (wait_reading_process_output, init_process_emacs):
446 (wait_reading_process_output): Put in a special case for WINDOWSNT
447 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
448 It's not clear this is needed, but it's a more-conservative change.
449 (create_process): Assume FD_CLOEXEC.
450 (create_process, create_pty): Assume O_NOCTTY.
451 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
452 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
453 Omit if not DOS_NT, since F_GETFL is not defined there.

455 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
457 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
458 lack it, since gnulib guarantees this.
459 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
461 2012-11-17 Eli Zaretskii <eliz@gnu.org>
463 * w32.c (faccessat): Pretend that directories have the execute bit
464 set. Emacs expects that, e.g., in files.el:cd-absolute.
466 * w32proc.c (create_child): Don't clip the PID of the child
467 process to fit into an Emacs integer, as this is no longer a
469 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
470 reaping only the process specified by PID argument, if that is
471 positive. Use PID instead of dead_child to know which process to
472 reap. Wait for the child to die only if WNOHANG is not in
474 (sys_select): Don't set dead_child.
476 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
477 as it is no longer needed.
479 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
481 (record_child_status_change): Remove the setting of
482 record_at_most_one_child for the !WNOHANG case.
484 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
486 Fix problems in ns port found by static checking.
487 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
488 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
489 not to process group.
490 (ns_select): Use emacs_write, not write, as that's more robust
491 in the presence of signals.
492 (fd_handler:): Check for read errors.
494 2012-11-16 Glenn Morris <rgm@gnu.org>
496 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
498 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
500 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
502 2012-11-16 Eli Zaretskii <eliz@gnu.org>
504 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
505 use the same value of thread handle.
506 (start_timer_thread): If the timer thread exited (due to error),
507 clean up by closing the two handles it used. Duplicate the caller
508 thread's handle here, so it gets duplicated only once, when
509 launching the timer thread. Set priority of the timer thread, not
511 (getitimer): Don't duplicate the caller thread's handle here.
514 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
516 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
519 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
521 Remove no-longer-used pty_max_bytes variable.
522 * process.c (pty_max_bytes): Remove; unused.
523 (send_process): Do not set it.
525 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
527 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
530 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
532 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
533 This follows up on the 2012-09-29 patch that removed indirection
534 for the 'function' field. Reported by Sergey Vinokurov in
535 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
537 2012-11-14 Eli Zaretskii <eliz@gnu.org>
539 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
540 different name, as the MS runtime does not have such a function,
541 and probably never will.) All callers changed. Ignore DIRFD
542 value if PATH is an absolute file name, to match Posix spec
543 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
546 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
548 * xdisp.c (echo_area_display, redisplay_internal):
549 Omit redundant check whether frame_garbaged is set.
551 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
553 Use faccessat, not access, when checking file permissions (Bug#12632).
554 This fixes a bug that has been present in Emacs since its creation.
555 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
556 which must set some sort of record. (Torek's bug report was against
557 a predecessor of GNU Emacs, but GNU Emacs happened to have the
558 same common flaw.) See Torek's Usenet posting
559 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
560 Posted: Fri Apr 8 14:18:56 1983.
561 * Makefile.in (LIB_EACCESS): New macro.
563 * callproc.c (init_callproc):
564 * charset.c (init_charset):
565 * fileio.c (check_existing, check_executable, check_writable)
567 * lread.c (openp, load_path_check):
568 * process.c (allocate_pty):
570 Use effective UID when checking permissions, not real UID.
571 * callproc.c (init_callproc):
572 * charset.c (init_charset):
573 * lread.c (load_path_check, init_lread):
574 Test whether directories are accessible, not merely whether they exist.
575 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
576 * fileio.c (check_existing, check_executable, check_writable)
578 Use symbolic names instead of integers for the flags, as they're
580 (check_writable): New arg AMODE. All uses changed.
581 Set errno on failure.
582 (Ffile_readable_p): Use faccessat, not stat + open + close.
583 (Ffile_writable_p): No need to call check_existing + check_writable.
584 Just call check_writable and then look at errno. This saves a syscall.
585 dir should never be nil; replace an unnecessary runtime check
586 with an eassert. When checking the parent directory of a nonexistent
587 file, check that the directory is searchable as well as writable, as
588 we can't create files in unsearchable directories.
589 (file_directory_p): New function, which uses 'stat' on most platforms
590 but faccessat with D_OK (for efficiency) if WINDOWSNT.
591 (Ffile_directory_p, Fset_file_times): Use it.
592 (file_accessible_directory_p): New function, which uses a single
593 syscall for efficiency.
594 (Ffile_accessible_directory_p): Use it.
595 * xrdb.c (file_p): Use file_directory_p.
596 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
597 * lread.c (openp): When opening a file, use fstat rather than
598 stat, as that avoids a permissions race. When not opening a file,
599 use file_directory_p rather than stat.
600 (dir_warning): First arg is now a usage string, not a format.
601 Use errno. All uses changed.
602 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
603 that merely introduced a race.
604 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
605 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
606 and similarly for the other O_* flags.
607 * w32.c (sys_faccessat): Rename from sys_access and switch to
608 faccessat's API. All uses changed.
609 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
610 (magic_db): Rename from magic_file_p.
611 (magic_db, search_magic_path): Return an XrmDatabase rather than a
612 char *, so that we don't have to test for file existence
613 separately from opening the file for reading. This removes a race
614 fixes a permission-checking problem, and simplifies the code.
616 (file_p): Remove; no longer needed.
618 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
620 Omit glyphs initialization at startup.
621 * dispnew.c (glyphs_initialized_initially_p): Remove.
622 (adjust_frame_glyphs_initially): Likewise. Adjust users.
623 (Fredraw_frame): Move actual code from here...
624 (redraw_frame): ...to here. Add eassert. Adjust comment.
625 (Fredraw_display): Use redraw_frame.
626 * xdisp.c (clear_garbaged_frames): Likewise.
628 2012-11-13 Eli Zaretskii <eliz@gnu.org>
630 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
631 passed to pint2str and pint2hrstr to be at most the size of the
632 frame's decode_mode_spec_buffer. This avoids crashes with very
633 large values of FIELD_WIDTH argument to decode_mode_spec.
636 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
638 Fix a race with verify-visited-file-modtime (Bug#12863).
639 Since at least 1991 Emacs has ignored an mtime difference of no
640 more than one second, but my guess is that this was to work around
641 file system bugs that were fixed long ago. Since the race is
642 causing problems now, let's remove that code.
643 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
644 whose time stamp is off by no more than a second. Insist that the
645 file time stamps match exactly.
647 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
649 * frame.h (struct frame): Convert external_tool_bar member to
650 1-bit unsigned bitfield.
651 * termhooks.h (struct terminal): Remove mouse_moved member since
652 all users are long dead. Adjust comment on mouse_position_hook.
654 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
656 Simplify by using FOR_EACH_FRAME here and there.
657 * frame.c (next_frame, prev_frame, other_visible_frames)
658 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
659 * w32term.c (x_window_to_scroll_bar): Likewise.
660 * window.c (window_list): Likewise.
661 * xdisp.c (x_consider_frame_title): Likewise.
662 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
663 * xfns.c (x_window_to_frame, x_any_window_to_frame)
664 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
665 * xmenu.c (menubar_id_to_frame): Likewise.
666 * xselect.c (frame_for_x_selection): Likewise.
667 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
668 (x_window_to_menu_bar): Likewise.
669 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
671 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
673 * data.c (Qdefalias_fset_function): Now static.
675 Another tweak to vectorlike_header change.
676 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
677 Remove, and replace all uses with ...
678 (next_in_free_list, set_next_in_free_list):
679 New functions, which respect C's aliasing rules better.
681 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
683 * window.c (list4i): Rename from 'quad'. All uses changed.
684 Needed because <sys/types.h> defines 'quad' on Solaris 10.
686 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
688 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
689 warning about mixing declarations and code in ISO C90.
691 2012-11-10 Martin Rudalics <rudalics@gmx.at>
693 * window.c (Fsplit_window_internal): Set combination limit of
694 new parent window to t iff Vwindow_combination_limit is t;
695 fixing a regression introduced with the change from 2012-09-22.
696 (Fset_window_combination_limit): Fix doc-string.
698 2012-11-10 Eli Zaretskii <eliz@gnu.org>
700 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
701 amount when the scroll margins are too large. When scrolling
702 backwards in the buffer, give up if cannot reach point or the
703 scroll margin within a reasonable number of screen lines.
704 Fixes point position in window under scroll-up/down-aggressively when
705 point is positioned many lines beyond the window top/bottom.
708 * ralloc.c (relinquish): If real_morecore fails to return memory
709 to the system, don't crash; instead, leave the last heap
710 unchanged and return. (Bug#12774)
712 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
714 * lisp.h (AUTOLOADP): New macro.
715 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
716 * data.c (Ffset): Remove special ad-advice-info handling.
717 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
719 (Finteractive_form): Simplify.
720 (Fquo): Don't insist on having at least 2 arguments.
721 (Qdefalias_fset_function): New var.
723 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
725 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
727 * nsfont.m (Qcondensed, Qexpanded): New variables.
728 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
729 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
731 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
733 Fix recently introduced crash on MS-Windows (Bug#12839).
734 * w32term.h (struct scroll_bar): Use convenient header.
735 (SCROLL_BAR_VEC_SIZE): Remove.
736 * w32term.c (x_scroll_bar_create): Use VECSIZE.
738 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
740 Tweak last vectorlike_header change.
741 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
742 vectorlike object on the free list. This is introduced to avoid
743 some (but not all) pointer casting and aliasing problems, see
744 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
745 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
747 (xvectype, xvecsize): Use them to examine Lisp_Object values.
749 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
751 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
752 been removed, so remove them here also.
754 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
756 * doc.c (Fdocumentation): Handle new property
757 dynamic-docstring-function to replace the old ad-advice-info.
759 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
761 * fns.c (Qeql, hashtest_eq): Now static.
763 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
765 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
766 * fns.c (hashfn_eq, hashfn_eql, sxhash):
767 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
768 * buffer.c (compare_overlays): Use XLI rather than XHASH.
770 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
772 Use same hash function for hashfn_profiler as for hash_string etc.
773 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
774 * lisp.h (sxhash_combine): New inline function, with the contents
775 of the old SXHASH_COMBINE.
776 * profiler.c (hashfn_profiler): Use it, instead of having a
777 special hash function containing a comparison that always yields 1.
779 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
781 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
782 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
783 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
786 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
788 * image.c (xpm_make_color_table_h): Fix compiler error because
789 make_hash_table changed.
791 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
793 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
795 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
797 Use ad-hoc comparison function for the profiler's hash-tables.
798 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
799 (make_log): Use them.
800 (handle_profiler_signal): Don't inhibit quit any longer since we don't
801 call Fequal any more.
802 (Ffunction_equal): New function.
803 (cmpfn_profiler, hashfn_profiler): New functions.
804 (syms_of_profiler): Initialize them.
805 * lisp.h (struct hash_table_test): New struct.

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

814 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.
815 (syms_of_fns): Initialize them.

825 value of w32-scroll-lock-modifier is neither nil nor one of the
826 known key modifiers. (Bug#12806)
828 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
830 Shrink struct vectorlike_header to the only size field.
831 * lisp.h (enum pvec_type): Avoid explicit enum member values.
833 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
834 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
835 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
836 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
837 information from the vector header. Adjust comment.

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

873 (xvecsize): New command.
875 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
877 * keyboard.c (event_to_kboard): Do not dereference
878 frame_or_window field of SELECTION_REQUEST_EVENT
879 and SELECTION_CLEAR_EVENT events (Bug#12814).
880 * xterm.h (struct selection_input_event): Adjust comment.
882 2012-11-07 Eli Zaretskii <eliz@gnu.org>
884 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
885 such as Scroll Lock, if the respective keys are treated as
886 function keys, not as modifiers. This avoids destroying non-ASCII
887 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
889 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
891 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
893 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
895 Restore some duplicate definitions (Bug#12814).
896 This undoes part of the 2012-11-03 changes. Some people build
897 with plain -g rather than with -g3, and they need the duplicate
898 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
899 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
900 Define as macros, as well as as enums or as constants.
902 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
904 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
905 to keypad keys (Bug#12816).
907 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
909 Minor adjustments of recently-changed frame functions.
910 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
911 known to be a frame (we're in the FRAMEP branch).
912 * lisp.h (Qframep): Remove decl. frame.h declares this.
913 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
914 since they're meant for Lisp fixnum values.
916 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
918 * window.c (Fwindow_combination_limit): Revert to the only
919 required argument and adjust docstring as suggested in
920 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
921 by Martin Rudalics <rudalics@gmx.at>.
923 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
925 Widely used frame validity and checking functions.
926 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.

930 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
931 (Fframe_pointer_visible_p): Use decode_any_frame.
932 (Fmake_frame_visible, Fmake_frame_invisible, Ficonify_frame)
933 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
934 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
935 (Fframe_focus): Likewise. Allow zero number of arguments.
937 (frame_buffer_list, frame_buffer_predicate): Remove.
938 * lisp.h (frame_buffer_predicate): Remove prototype.
939 * buffer.c (Fother_buffer): Use decode_any_frame.
940 * xdisp.c (Ftool_bar_lines_needed): Likewise.
941 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
942 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
943 (Fclose_font, Ffont_info): Use decode_live_frame.
944 * fontset.c (check_fontset_name): Likewise.
945 * terminal.c (Fframe_terminal): Likewise.
946 * w32fns.c (check_x_frame): Likewise.
947 * window.c (Fminibuffer_window, Fwindow_at)
948 (Fcurrent_window_configuration): Likewise.
949 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
950 Likewise. Allow zero number of arguments. Adjust docstring.
951 * dispnew.c (Fredraw_frame): Likewise.
952 * xfaces.c (frame_or_selected_frame): Remove.
953 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
954 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
955 (Fframe_face_alist): Use decode_live_frame.
956 * xfns.c (check_x_frame): Likewise.
958 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
960 * window.c (quad): New function.
961 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
962 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
963 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
964 (Fwindow_line_height): Use it.
965 (Fwindow_fringes): Use list3.
966 (Fwindow_scroll_bars): Use list4.
967 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
968 (Fwindow_combination_limit): Allow zero number of arguments.
970 2012-11-05 Eli Zaretskii <eliz@gnu.org>
972 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
974 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
975 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
976 file descriptor 2 for standard error. (Bug#12805)
978 2012-11-05 Chong Yidong <cyd@gnu.org>
980 * process.c (wait_reading_process_output): Revert previous change.
982 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
984 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
985 This removes code that has been obsolete since around 1990.
986 * callproc.c (Fcall_process):
988 * process.c (create_process):
989 * term.c (dissociate_if_controlling_tty):
990 Assume setsid exists.
991 * callproc.c (child_setup): Assume setpgid exists and behaves as
992 per POSIX.1-1988 or later.
993 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
994 * emacs.c (shut_down_emacs):
995 * sysdep.c (sys_suspend, init_foreground_group):
996 Assume getpgrp behaves as per POSIX.1-1998 or later.
997 * msdos.c (setpgrp): Remove.
998 (tcgetpgrp, setpgid, setsid): New functions.
999 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
1000 * term.c (no_controlling_tty): Remove; unused.
1001 * w32proc.c (setpgrp): Remove.
1002 (setsid, tcgetpgrp): New functions.
1004 Simplify by assuming __fpending.
1005 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
1006 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
1007 Do not assume that __fpending's result fits in int.
1009 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
1011 Remove EMACS_OUTQSIZE+sleep hack.
1012 * dispnew.c (update_frame_1): Remove hack for terminals slower
1013 than 2400 bps, which throttled Emacs by having it sleep.
1014 This code hasn't worked since at least 2007, when the multi-tty stuff
1015 was added, and anyway those old terminals are long dead.
1016 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
1017 without the dispnew.c change, as dispnew.c doesn't include systty.h.
1019 Fix data-loss with --version (Bug#9574).
1020 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
1021 as we can't assume that emacs_strerror is initialized, and strerror
1022 is good enough here.
1023 (main): Invoke atexit earlier, to catch earlier instances of
1024 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
1026 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
1028 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
1029 (keyDown): Remap keypad keys to X11 virtual key codes.
1031 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
1033 Fix data-loss with --batch (Bug#9574).
1034 * emacs.c: Include <close-stream.h>.
1035 (close_output_streams): New function.
1036 (main): Pass it to atexit, so that Emacs closes stdout and stderr
1037 and handles errors appropriately.
1038 (Fkill_emacs): Don't worry about flushing, as close_output_stream
1041 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
1042 The symptom is a diagnostic "GLib-WARNING **: In call to
1043 g_spawn_sync(), exit status of a child process was requested but
1044 SIGCHLD action was set to SIG_IGN and ECHILD was received by
1045 waitpid(), so exit status can't be returned." The diagnostic
1046 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
1047 The real bug is a race condition between Emacs and glib: Emacs
1048 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
1049 so that glib can't find it. Work around the bug by invoking
1050 waitpid only on subprocesses that Emacs itself creates.
1051 * process.c (create_process, record_child_status_change):
1052 Don't use special value -1 in pid field, as the caller now must
1053 know the pid rather than having the callee infer it.
1054 The inference was sometimes incorrect anyway, due to another race.
1055 (create_process): Set new 'alive' member if child is created.
1056 (process_status_retrieved): New function.
1057 (record_child_status_change): Use it.
1058 Accept negative 1st argument, which means to wait for the
1059 processes that Emacs already knows about. Move special-case code
1060 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
1061 processes that have already been waited for, by testing and
1062 clearing new 'alive' member.
1063 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
1064 now does this internally.
1065 (handle_child_signal): Let record_child_status_change do all
1066 the work, since we do not want to reap all exited child processes,
1067 only the child processes that Emacs itself created.
1068 * process.h (Lisp_Process): New boolean member 'alive'.
1070 Omit duplicate definitions no longer needed with gcc -g3.
1071 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
1072 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
1073 Define only as macros. There's no longer any need to also define
1074 these symbols as enums or as constants, since we now assume
1075 gcc -g3 when debugging.
1077 2012-11-03 Eli Zaretskii <eliz@gnu.org>
1079 * lisp.mk: Adjust comments to the fact that term/internal is now
1080 loaded from loadup.el.
1082 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
1083 (msdos_fatal_signal): New function.
1084 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
1087 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
1088 for GCC versions before 4.
1089 (emacs_raise): Define to call msdos_fatal_signal.
1091 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
1092 iterator when starting in the middle of a display or overlay
1095 2012-11-03 Chong Yidong <cyd@gnu.org>
1097 * process.c (wait_reading_process_output): Clean up the last
1100 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
1102 * process.c (wait_reading_process_output): Avoid a race condition
1103 with SIGIO delivery (Bug#11536).
1105 2012-11-03 Chong Yidong <cyd@gnu.org>
1107 * buffer.c (cursor_type): Untabify docstring.
1109 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1111 * frame.h (struct frame): Drop can_have_scroll_bars member
1112 which is meaningless for a long time. Adjust comments.
1113 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
1114 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
1116 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1118 * window.c (decode_next_window_args): Update window arg after
1119 calling decode_live_window and so fix crash reported at
1120 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
1121 by Juanma Barranquero <lekktu@gmail.com>.
1122 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
1123 * font.c (Ffont_at): Likewise.
1125 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
1127 * widget.c (resize_cb): New function.
1128 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
1129 (EmacsFrameResize): Check if all is up to date before changing frame
1132 2012-11-02 Eli Zaretskii <eliz@gnu.org>
1134 Implement backtrace output for fatal errors on MS-Windows.
1135 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
1136 (BACKTRACE_LIMIT_MAX): New macro.
1137 (w32_backtrace): New function.
1138 (emacs_abort): Use w32_backtrace when the user chooses not to
1139 attach a debugger. Update the text of the abort dialog.
1141 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1143 Window-related stuff cleanup here and there.
1144 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
1145 Use decode_any_window.
1146 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
1147 * xdisp.c (Fformat_mode_line): Likewise.
1148 * font.c (Ffont_at): Use decode_live_window.
1149 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
1150 * window.c (decode_next_window_args): Likewise.
1151 (decode_any_window): Remove static.
1152 * window.h (decode_any_window): Add prototype.
1153 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
1154 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
1157 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1159 Remove pad from struct input_event.
1160 * termhooks.h (struct input_event): Remove padding field.
1162 * keyboard.c (event_to_kboard): Simplify because frame_or_window
1163 member is never cons for a long time. Adjust comment.
1164 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
1165 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
1166 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
1167 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
1169 2012-11-01 Eli Zaretskii <eliz@gnu.org>
1171 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
1173 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
1175 Fix crash when using Emacs as commit editor for git (Bug#12697).
1176 * callproc.c (setpgrp): Remove macro, as we now use setpgid
1177 and it is configured in conf_post.h.
1178 (Fcall_process): Don't invoke both setsid and setpgid; the former
1179 is enough, if it exists.
1180 * callproc.c (Fcall_process, child_setup):
1181 * process.c (create_process): Use setpgid.
1182 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
1184 * dispnew.c (init_display): Initialize the foreground group
1185 if we are running a tty display.
1186 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
1187 * lisp.h (init_foreground_group): New decl.
1188 * sysdep.c (inherited_pgroup): New static var.
1189 (init_foreground_group, tcsetpgrp_without_stopping)
1190 (narrow_foreground_group, widen_foreground_group): New functions.
1191 (init_sys_modes): Narrow foreground group.
1192 (reset_sys_modes): Widen foreground group.
1194 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
1196 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
1198 2012-10-31 Martin Rudalics <rudalics@gmx.at>
1200 * minibuf.c (read_minibuf): Restore current buffer since
1201 choose_minibuf_frame calling Fset_frame_selected_window may
1202 change it (Bug#12766).
1204 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
1206 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
1208 2012-10-30 Kenichi Handa <handa@gnu.org>
1210 * font.c (Ffont_at): If WINDOW is specified and it is not
1211 displaying the current buffer, signal an error.
1213 2012-10-29 Daniel Colascione <dancol@dancol.org>
1215 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
1216 In preparation for fixing bug#12739, move these functions from
1219 * coding.h, coding.c: ... to here, and compile them only when
1220 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
1221 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
1223 2012-10-28 Eli Zaretskii <eliz@gnu.org>
1225 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
1226 (timer_loop, getitimer, setitimer): Use it instead of
1227 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
1229 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
1232 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
1234 * nsterm.m (NO_APPDEFINED_DATA): New define.
1235 (last_appdefined_event_data): New variable
1236 (last_appdefined_event): Remove.
1237 (ns_select): Initialize t from last_appdefined_event_data instead
1238 of [last_appdefined_event data1].
1239 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
1240 remove last_appdefined_event (Bug#12698).
1242 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
1244 * frame.c (x_set_font): Catch internal error.
1246 2012-10-27 Eli Zaretskii <eliz@gnu.org>
1248 Avoid overflow in w32 implementation of interval timers.
1249 When possible, for ITIMER_PROF count only times the main thread
1251 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
1252 'volatile ULONGLONG' types. All the other data which was
1253 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
1254 (GetThreadTimes_Proc): New typedef.
1255 (w32_get_timer_time): New function, returns a suitable time value
1257 (timer_loop): Enter critical section when accessing ULONGLONG
1258 values of the itimer_data struct, as these accesses are no longer
1259 atomic. Call 'w32_get_timer_time' instead of 'clock'.
1260 Remove unused variable.
1261 (init_timers): Initialize s_pfn_Get_Thread_Times.
1262 (start_timer_thread): Don't assign itimer->caller_thread here.
1263 (getitimer): Assign itimer->caller_thread here.
1264 (setitimer): Always call getitimer to get the value of ticks_now.
1265 (sys_spawnve): Avoid compiler warning about format mismatch.
1267 2012-10-26 Eli Zaretskii <eliz@gnu.org>
1269 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
1270 mouse movement events if the menu bar is active. This avoids
1271 producing a busy "hour-glass" cursor by Windows if the mouse
1272 pointer is positioned over a tooltip shown for some menu item.
1274 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
1276 Don't assume process IDs fit in int.
1277 * emacs.c (shut_down_emacs) [!DOS_NT]:
1278 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
1279 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
1280 Use pid_t, not int, to store process IDs, as 'int'
1281 is not wide enough on a few platforms (e.g., AIX and IRIX).
1283 2012-10-23 Kenichi Handa <handa@gnu.org>
1285 The following change is to make face-font-rescale-alist work
1286 correctly for non-ASCII fonts.
1288 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
1289 (font_open_for_lface): Handle Vface_font_rescale_alist.
1291 2012-10-23 Chong Yidong <cyd@gnu.org>
1293 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
1295 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
1297 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
1299 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
1301 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
1304 2012-10-21 Glenn Morris <rgm@gnu.org>
1306 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
1308 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
1310 Port to OpenBSD 5.1.
1311 * frame.c (Fmouse_position, Fmouse_pixel_position):
1312 * xdisp.c (produce_stretch_glyph):
1313 Declare local vars only when they're needed.
1314 This is clearer and avoids a warning on OpenBSD about unused vars.
1315 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
1316 This is safer, and avoids OpenBSD warnings about unused vars.
1317 * keyboard.c (record_menu_key): Remove unnecessary decl.
1318 (poll_timer): Define only if POLL_FOR_INPUT is defined.
1319 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
1320 as our definition clashes with OpenBSD's.
1321 * xfaces.c (load_face_colors, check_lface_attrs)
1322 (get_lface_attributes_no_remap, get_lface_attributes)
1323 (lface_fully_specified_p, x_supports_face_attributes_p)
1324 (tty_supports_face_attributes_p, face_fontset, realize_face)
1325 (realize_x_face, realize_tty_face):
1326 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
1327 merely Lisp_Object *. This is more informative and avoids
1328 a warning on OpenBSD about accessing beyond an object's size.
1330 2012-10-20 Chong Yidong <cyd@gnu.org>
1332 * lread.c (Fload): Doc fix (Bug#12592).
1334 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
1336 * font.c (Ffont_at): Fix previous change.
1338 2012-10-19 Eli Zaretskii <eliz@gnu.org>
1340 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
1341 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
1344 * alloc.c (NSTATICS): Decrease to 0x800.
1346 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>
1348 * fns.c (Fnreverse): Include the problem element when signalling an
1351 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
1353 * nsterm.m (ns_select): Check writefds before call to
1354 FD_ISSET (Bug#12668).
1356 2012-10-18 Daniel Colascione <dancol@dancol.org>
1358 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
1359 (staticpro): If we run out of staticpro slots, die with an
1360 informative error instead of just calling emacs_abort.
1362 2012-10-18 Martin Rudalics <rudalics@gmx.at>
1364 Fix two flaws reported by Dmitry Antipov.
1365 * window.c (Ftemp_output_buffer_show): Remove.
1366 (Fwindow_vscroll, Fset_window_vscroll): Use decode_live_window.
1367 (syms_of_window): Remove defsubr for Stemp_output_buffer_show.
1369 2012-10-17 Eli Zaretskii <eliz@gnu.org>
1371 * makefile.w32-in ($(BLD)/w32.$(O)):
1372 ($(BLD)/vm-limit.$(O)):
1374 ($(BLD)/unexw32.$(O)):
1375 ($(BLD)/fileio.$(O)):
1376 ($(BLD)/dispnew.$(O)): Update dependencies.
1378 * w32term.h (w32_initialize_display_info, initialize_w32_display):
1381 * w32proc.c: Include ctype.h.
1383 * w32.h (init_environment, check_windows_init_file)
1384 (syms_of_ntproc, syms_of_ntterm, dostounix_filename)
1385 (unixtodos_filename, init_winsock, srandom, random, sys_pipe)
1386 (set_process_dir, sys_spawnve, register_child, sys_sleep, getwd)
1387 (sys_link): Add prototypes.
1389 * w32.c: Include w32select.h.
1390 (sys_access, e_malloc, sys_select): Add prototypes.
1391 (emacs_gnutls_pull): 'timeout' is now EMACS_TIME, not struct timeval.
1393 * vm-limit.c [WINDOWSNT]: Include w32heap.h.
1395 * unexw32.c: Include lisp.h and w32.h.
1397 * term.c [WINDOWSNT]: Include w32term.h.
1399 * process.c [WINDOWSNT]: Add prototype of sys_select.
1401 * fileio.c [WINDOWSNT]: Include w32.h.

1461 * image.c (init_tiff_functions, init_imagemagick_functions)
1462 (init_svg_functions): Fix cygw32 build break by using these
1463 functions only when WINDOWSNT _and_ HAVE_NTGUI.

1518 * fileio.c (check_existing): New function.
1519 (make_temp_name, Ffile_exists_p, Ffile_writable_p): Call it
1520 instead of calling 'stat', when what's needed is to check whether
1521 a file exists. This avoids expensive system calls on MS-Windows.
1524 * w32.c (init_environment): Call 'check_existing' instead of 'stat'.
1526 * lread.c (openp) [WINDOWSNT]: Call 'access' instead of 'stat' to

1616 (detect_input_pending_run_timers):
1617 * process.c (wait_reading_process_output):
1618 Use unsigned for counter where wraparound-on-overflow is desired,
1619 since unsigned is guaranteed to have that behavior and signed is not.
1620 (read_char): Use ptrdiff_t for string length.
1621 (get_input_pending): Remove first argument, since it was always
1622 the same pointer-to-int (now pointer-to-boolean) &input_pending,
1623 and behave as if it had that value. Return new value of
1624 input_pending. All callers changed.
1625 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
1626 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
1628 * keymap.c (push_key_description): Omit last arg, which was always 1.
1629 All callers changed.
1631 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.
1633 2012-10-10 Juanma Barranquero <lekktu@gmail.com>

1649 Don't include termopts.h.
1651 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
1653 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
1655 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
1657 * commands.h (immediate_quit): Remove duplicate decl.
1659 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
1661 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles

1664 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
1666 2012-10-09 Eli Zaretskii <eliz@gnu.org>
1668 * w32fns.c (w32_last_error): Change the return value to DWORD, to
1669 match what GetLastError returns. Explain why the function is
1672 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
1673 'is_tooltip_frame', to avoid confusion with its global namesake.
1675 2012-10-08 Daniel Colascione <dancol@dancol.org>
1677 * xdisp.c (start_hourglass): Call w32_note_current_window when
1678 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
1679 build that caused Emacs to display the hourglass cursor forever.
1681 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
1682 which is broken under remote desktop, calculate the number of
1683 colors available for a display based on the display's number of
1684 planes and number of bits per pixel per plane. (bug#10397).
1686 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
1688 * nsfont.m (Vfonts_in_cache): New variable.
1689 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
1690 are used. Add cached fonts to Vfonts_in_cache.
1691 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
1693 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
1695 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
1697 (FONT_H): Define after FRAME_H.
1698 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
1699 Update dependencies.
1701 * w32term.c: Remove leftover declaration of keyboard_codepage.
1703 2012-10-08 Eli Zaretskii <eliz@gnu.org>
1705 * makefile.w32-in (FONT_H): Add $(FRAME_H).
1706 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
1707 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
1708 (GLOBAL_SOURCES): Add cygw32.c.
1709 ($(BLD)/unexw32.$(O)):
1711 ($(BLD)/w32console.$(O)):
1712 ($(BLD)/w32fns.$(O)):
1713 ($(BLD)/w32heap.$(O)):
1714 ($(BLD)/w32menu.$(O)):
1715 ($(BLD)/w32proc.$(O)): Add w32common.h.
1717 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
1719 (x_to_w32_color): Don't modify the argument, modify a copy instead.
1721 2012-10-08 Daniel Colascione <dancol@dancol.org>
1723 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
1724 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
1725 accidental message numbering hole. Change other messages to
1728 * w32select.h (HAVE_W32SELECT): Remove.
1730 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
1731 w32common.h instead of w32heap.h.
1733 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
1734 (get_allocation_unit, get_processor_type, get_w32_major_version)
1735 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
1736 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
1737 (OS_NT, os_subtype, cache_system_info): Move declarations to
1740 * w32heap.c: Include w32common.h.
1741 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
1742 (w32_minor_version, w32_build_number, w32_subtype):
1743 Remove duplicate definitions.
1745 * w32fns.c: Include w32common.h; include w32heap.h only in
1748 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
1749 Use `report_file_error' instead of `error' in order to better
1750 inform users of what went wrong. Increase NTGUI_UNICODE file
1751 dialog box file name length to 32k, the maximum allowed by the NT
1754 * w32common.h: New file.
1755 (ROUND_UP, ROUND_DOWN, get_page_size)
1756 (get_allocation_unit, get_processor_type, get_w32_major_version)
1757 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
1758 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
1759 (OS_NT, os_subtype, cache_system_info): Move here.
1761 * unexw32.c, unexcw.c: Include w32common.h.
1763 * emacs.c (main): Use (defined (WINDOWSNT) || defined
1764 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
1765 to call syms_of_w32select.
1767 * cygw32.h: Remove obsolete EXFUN declarations.
1769 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.

1772 of w32inevt.o from SOME_MACHINE_OBJECTS.
1774 2012-10-08 Daniel Colascione <dancol@dancol.org>
1776 * image.c: Permanent fix for JPEG compilation issue --- limit
1777 jpeglib `boolean' redefinition to Cygwin builds.
1779 2012-10-08 Eli Zaretskii <eliz@gnu.org>
1781 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
1783 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
1786 2012-10-08 Daniel Colascione <dancol@dancol.org>
1788 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
1789 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
1790 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
1791 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
1792 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
1793 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
1794 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
1795 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
1796 now a supported configuration.
1798 * Makefile.in: consolidate image variables into LIBIMAGE; add
1799 W32_OBJ and W32_LIBS. Compile new files.
1802 (_DebPrint) declare tracing facility for W32 debugging. We need
1803 to unify tracing later.
1805 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
1806 unconditional use of W32 Unicode functions. Cygwin runs only on
1807 100% Unicode operating systems.
1809 * cygw32.c: New file. Define Cygwin-specific facilities.
1810 (Fcygwin_convert_path_to_windows)
1811 (Fcygwin_convert_path_from_windows): New user functions for
1812 accessing Cygwin path-munging routines.
1814 * cygw32.h: New file.
1815 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
1816 UTF-16LE strings temporarily inside non-Lisp-visible string
1819 (w32_strerror): Just what it says on the tin.
1821 * emacs.c: Make the NS fork-then-exec code for daemon-launching
1822 also run for Cygwin; both systems have the same problem with using
1823 GUI facilities in a forked child. Also call syms_of_cygw32,
1824 syms_of_w32select in correct places.
1826 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
1827 needs fork-then-exec for daemon launching.
1829 * font.h: Include frame.h.
1831 * image.c: Use the image library cache machinery only when we're
1832 compiling for native WINDOWSNT; Cygwin can use shared libraries
1833 like any other Unixlike system.
1835 * keyboard.c: Clarify a comment regarding the input loop.
1837 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
1838 functions directly instead of trying to detect at runtime that our
1839 host operating system supports them. We make this change for two
1840 reasons: Cygwin lacks support for the multibyte character
1841 conversion functions used by the legacy menu code, and Cygwin
1842 never needs to rely on non-Unicode APIs.
1844 * unexw32.c (hinst): Declare extern.
1846 * w32.c: Change header order;
1847 (w32_strerror): Move to w32fns.c because we need it for
1848 non-WINDOWSNT builds.
1850 * w32.h: Add #error macro to make sure we don't include w32.h for
1851 Cygwin builds. Remove w32select declarations.
1853 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
1854 w32fns.c. w32console.c is WINDOWSNT-only.
1856 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
1857 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
1859 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
1860 (w32_major_version, w32_minor_version, w32_build_number)
1861 (os_subtype, sound_type): Define here
1862 (w32_defined_color): Make color parameter const for consistency
1863 with other _defined_color functions.
1864 (w32_createwindow): Unconditionally call w32_init_class instead of
1865 doing so only when hprevinst is non-NULL. Plumbing hprevinst
1866 through the code is complex and unnecessary because class
1867 registration is practically free.
1868 (w32_name_of_message): New EMACSDEBUG-only function.
1869 (Fset_message_beep): Move here
1870 (Fx_open_connection): Require that the display name for Windows be
1871 "w32" for consistency, emacsclient disambiguation, and maybe, one
1872 day, multi-window-system support.
1873 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
1874 Cygwin files for W32 GUI facilities, since these clearly don't

1900 descriptor the system used to tell us about pending thread
1903 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
1904 that prevented compilation under non-WINDOWSNT systems.

1911 (prepend_msg, w32_message_fd): Declare globally.
1914 (keyboard_handle): Use only when WINDOWSNT.
1915 (notify_msg_ready): New function. Posts a message to the main
1916 thread's message queue under CYGWIN, which wakes up the main
1917 thread from select(2) by making the /dev/windows file descriptor
1918 ready. Under WINDOWSNT, it sets an event the same way the old
1921 (post, prepend_msg): Actually call notify_msg_ready instead of
1922 setting the input event directly.
1924 2012-10-07 Eli Zaretskii <eliz@gnu.org>
1926 * ralloc.c (relinquish): If a heap is ready to be relinquished,
1927 but it still has blocs in it, don't return it to the system,
1928 instead of aborting. (Bug#12402)
1930 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>

1967 defined as a macro, as is done in Solaris.
1968 (sys_siglist_entries): New macro.
1969 (save_strsignal): Use it.
1970 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
1971 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
1973 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
1975 * nsfns.m (Fx_create_frame): Call x_default_parameter with
1976 fullscreen/Fullscreen.
1978 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
1979 tobar_height is new.
1981 * nsterm.m (x_make_frame_visible): Check for fullscreen.
1982 (ns_fullscreen_hook): Activate old style fullscreen with a timer.

1998 2012-10-05 Eli Zaretskii <eliz@gnu.org>
2000 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
2002 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
2003 that time stamps of directories could also be changed.
2004 Don't request the too broad GENERIC_WRITE, only the more restrictive
2005 FILE_WRITE_ATTRIBUTES access rights.
2007 * fileio.c (Fset_file_times): Special-case ignoring errors for
2008 directories only on MSDOS, not on MS-Windows.
2010 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
2012 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
2014 2012-10-04 Eli Zaretskii <eliz@gnu.org>

2021 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
2022 to avoid similar races.
2023 * keyboard.c (pending_signals): Now bool, not int.
2025 Port timers to OpenBSD, plus check for timer failures.
2026 OpenBSD problem reported by Han Boetes.

2029 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
2030 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
2031 like OpenBSD, which has timer_settime but does not declare it.
2032 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
2033 whether to use itimerspec-related primitives. All uses of
2034 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
2036 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2038 * profiler.c (handle_profiler_signal): Fix a malloc race
2039 that caused Emacs to hang on Fedora 17 when profiling Lisp.

2043 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
2045 2012-10-02 Eli Zaretskii <eliz@gnu.org>
2047 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
2048 consistent with the change in return value of 'safe_strsignal'.
2050 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2052 Prefer plain 'static' to 'static inline' (Bug#12541).

2060 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
2061 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
2062 Now 'static', not 'static inline'.
2064 Count overruns when profiling; change units to ns.
2065 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
2066 Give extra weight to samples after overruns, to attempt to count
2067 the time more accurately.
2068 (setup_cpu_timer): Change sampling interval units from ms to ns, since
2069 the underlying primitives nominally do ns.
2070 (Fprofiler_cpu_start): Document the change. Mention that
2071 the sampling intervals are only approximate.
2073 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
2075 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.

2078 case for the special 0 coding-system.
2080 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
2081 (Fmake_overlay): Remove redundant tests.
2082 (fix_start_end_in_overlays): Remove redundant recentering.
2084 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
2086 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
2087 Update dependencies.
2089 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2091 Fix a malloc race condition involving strsignal.
2092 A signal can arrive in the middle of a malloc, and Emacs's signal
2093 handler can invoke strsignal, which can invoke malloc, which is
2094 not portable. This race condition bug makes Emacs hang on GNU/Linux.
2095 Fix it by altering the signal handler so that it does not invoke
2097 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
2098 * process.c (status_message): Use const pointer, in case strsignal
2099 is #defined to safe_strsignal.
2100 * sysdep.c (sys_siglist, init_signals): Always define and
2101 initialize a substitute sys_siglist if the system does not define
2102 one, even if HAVE_STRSIGNAL.
2103 (safe_strsignal): Rename from strsignal. Always define,
2104 using sys_siglist. Return a const pointer.
2105 * syssignal.h (safe_strsignal): New decl.
2106 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
2108 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2110 * w32proc.c (timer_loop): Fix code that waits for timer
2111 expiration, to avoid high CPU usage.
2113 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
2115 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
2116 (sweep_weak_table): Remove redundant prototypes.
2118 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
2120 * emacs.c: Move the inclusion of TERM_HEADER after including
2121 windows.h on WINDOWSNT. This avoids compilation problems with
2124 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2126 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
2127 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
2128 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
2129 as the previous version used 'void *'.
2131 * ralloc.c (ROUNDUP): Fix last change.
2132 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
2135 * w32proc.c <disable_itimers>: New static flag.
2136 (init_timers): Initialize it to zero, after creating the critical
2137 sections used by the timer threads.
2138 (term_timers): Set to 1 before deleting the critical sections.
2139 (getitimer, setitimer): If disable_itimers is non-zero, return an
2140 error indication without doing anything. Reported by Fabrice
2141 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
2142 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
2144 [!HAVE_SETITIMER]: Behave as the previous version that didn't
2147 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
2148 term_ntproc after all the other bookkeeping, to get timers working
2149 as long as possible.
2151 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2153 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
2154 Suggested by Juri Linkov in
2155 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
2157 Prefer plain 'static' to 'static inline' (Bug#12541).
2158 With static functions, modern compilers inline pretty well by
2159 themselves; advice from programmers often hurts as much as it helps.
2160 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
2161 this change shrinks the text size of the Emacs executable by 1.1%
2162 without affecting CPU significantly in my benchmark.
2163 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

2243 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
2245 Revert the FOLLOW-SYMLINKS change for file-attributes.
2246 Doing it right would require several changes to Tramp, and there's
2247 not enough time to get that tested before the freeze today.
2248 * dired.c (directory_files_internal, Ffile_attributes):
2251 * frame.c (x_report_frame_params): Port better to wider ints.
2252 Do not assume that EMACS_UINT is the same width as uprintmax_t,
2253 or that pointers can be printed in 15 decimal digits.
2254 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

2435 Suggested by Eli Zaretskii in
2436 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
2438 2012-09-30 Eli Zaretskii <eliz@gnu.org>
2440 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
2441 HAVE_TIMER_SETTIME is defined.

2445 Profiler improvements: more-accurate timers, overflow checks.
2446 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
2447 signal.h, setjmp.h. Include systime.h instead.
2448 (saturated_add): New function.

2455 All uses changed to store the new value.
2456 (handle_profiler_signal): Rename from sigprof_handler_1,
2457 for consistency with other handlers. Do not check whether
2458 cpu_log is a hash-table if garbage collecting, since it
2459 doesn't matter in that case.

2461 for consistency with other handlers.
2462 (setup_cpu_timer): New function, with much of what used to be in
2463 Fprofiler_cpu_start. Check for out-of-range argument.
2464 Prefer timer_settime if available, and prefer
2465 thread cputime clocks, then process cputime clocks, then
2466 monotonic clocks, to the old realtime clock. Use make_timeval
2467 to round more-correctly when falling back to setitimer.
2468 (Fprofiler_cpu_start): Use it.
2469 (Fprofiler_cpu_stop): Prefer timer_settime if available.
2470 Don't assume that passing NULL as the 2nd argument of setitimer

2473 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
2474 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
2475 non-fatal signal handlers. Ignore SIGPROF on startup.
2476 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
2477 in profiler.c, since sysdep.c now uses it.
2479 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

2535 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
2536 Since this stuff is now private to charset.c, there's no need for
2537 a public macro and no need to inline by hand.

2609 (sigaction): Rewrite to call sys_signal instead of duplicating its
2611 (sys_kill): Improve commentary.
2613 * w32.c (term_ntproc): Accept (and ignore) one argument, for
2614 consistency with a signature of a signal handler. All callers
2616 (init_ntproc): Accept an argument DUMPING. If dumping, don't
2617 install term_ntproc as a signal handler for SIGABRT, as that
2618 should be done by the dumped Emacs.
2620 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
2622 * w32select.c (term_w32select): Protect against repeated
2623 invocation by setting clipboard_owner to NULL after calling

2741 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
2742 fatal_error_backtrace.

2760 * emacs.c (terminate_due_to_signal): Reset signal handler here.
2761 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
2762 wanted even on POSIXish hosts, and it doesn't work on Windows.
2764 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
2766 * xterm.c (x_term_init): Call fixup_locale before and after calling
2767 gtk_init (Bug#12392).
2769 2012-09-23 Chong Yidong <cyd@gnu.org>
2771 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
2772 Vdynamic_library_alist.
2774 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
2775 (Fgnutls_available_p): Caller changed.
2777 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
2778 (Flibxml_parse_xml_region): Likewise.
2780 * dispextern.h (struct image_type): Remove arg from init function.
2782 * image.c (Finit_image_library, lookup_image_type)
2783 (define_image_type): Remove now-unneeded second arg.
2784 (init_xpm_functions, init_png_functions, init_jpeg_functions)
2785 (init_tiff_functions, init_gif_functions, init_svg_functions):
2786 Arglist and w32_delayed_load calling convention changed.
2787 (gs_type): Remove init_gs_functions; there is no such function.
2788 (valid_image_p, make_image): Fix caller to lookup_image_type.
2790 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
2792 Simplify and avoid signal-handling races (Bug#12471).
2794 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
2795 Avoid recursive loop if there's a fatal error in the function itself.
2796 * atimer.c (pending_atimers):
2797 * blockinput.h: Don't include "atimer.h"; no longer needed.
2798 (interrupt_input_pending): Remove. All uses removed.
2799 pending_signals now counts both atimers and ordinary interrupts.
2800 This is less racy than having three separate pending-signal flags.
2801 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
2803 Rename from their upper-case counterparts BLOCK_INPUT,
2804 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
2805 INPUT_BLOCKED_P, and turn into functions. All uses changed.
2806 This makes it easier to access volatile variables more accurately.
2807 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
2808 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
2809 that's more reliable if the code is buggy and sets
2810 interrupt_input_blocked to a negative value. All uses changed.
2811 * atimer.c (deliver_alarm_signal):
2812 Remove. No need to deliver this to the parent; any thread can
2813 handle this signal now. All uses replaced by underlying handler.
2814 * atimer.c (turn_on_atimers):
2815 * dispnew.c (handle_window_change_signal):
2816 * emacs.c (handle_danger_signal):
2817 * keyboard.c (kbd_buffer_get_event):
2818 Don't reestablish signal handler; not needed with sigaction.
2819 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
2821 Rework to avoid unnecessary accesses to volatile variables.
2822 (UNBLOCK_INPUT_TO): Now a function.
2823 (totally_unblock_input, unblock_input): New decls.
2824 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
2825 (init_data): Remove. Necessary stuff now done in init_signal.
2826 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
2827 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
2828 (fatal_error_code): Remove; no longer needed.
2829 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
2830 it doesn't always backtrace. All uses changed. No need to reset
2831 signal to default, since sigaction and/or die does that for us now.
2832 Use emacs_raise (FOO), not kill (getpid (), FOO).
2833 (main): Check more-accurately whether we're dumping.
2834 Move fatal-error setup to sysdep.c
2835 * floatfns.c: Do not include "syssignal.h"; no longer needed.
2836 * gtkutil.c (xg_get_file_name, xg_get_font):
2837 Remove no-longer-needed signal-mask manipulation.
2838 * keyboard.c, process.c (POLL_FOR_INPUT):
2839 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
2840 * keyboard.c (read_avail_input): Remove.
2841 All uses replaced by gobble_input.
2842 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
2843 (kbd_buffer_store_event_hold, gobble_input):
2844 (record_asynch_buffer_change) [USABLE_SIGIO]:
2845 (store_user_signal_events):
2846 No need to mess with signal mask.
2847 (gobble_input): If blocking input and there are terminals, simply
2848 set pending_signals to 1 and return. All hooks changed to not
2849 worry about whether input is blocked.
2850 (process_pending_signals): Clear pending_signals before processing
2851 them, in case a signal comes in while we're processing.
2852 By convention callers now test pending_signals before calling us.
2853 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
2854 New functions, to support changes to blockinput.h.
2855 (handle_input_available_signal): Now extern.
2856 (reinvoke_input_signal): Remove. All uses replaced by
2858 (quit_count): Now volatile, since a signal handler uses it.
2859 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
2860 All callers changed. Block SIGINT only if not already blocked.
2861 Clear sigmask reliably, even if Fsignal returns, which it can.
2862 Omit unnecessary accesses to volatile var.
2863 (quit_throw_to_read_char): No need to restore sigmask.
2864 * keyboard.c (gobble_input, handle_user_signal):
2865 * process.c (wait_reading_process_output):
2866 Call signal-handling code rather than killing ourselves.
2867 * lisp.h: Include <float.h>, for...
2868 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
2869 (pending_signals): Now volatile.
2870 (syms_of_data): Now const if IEEE floating point.
2871 (handle_input_available_signal) [USABLE_SIGIO]:
2872 (terminate_due_to_signal, record_child_status_change): New decls.
2873 * process.c (create_process): Avoid disaster if memory is exhausted
2874 while we're processing a vfork, by tightening the critical section
2876 (send_process_frame, process_sent_to, handle_pipe_signal)
2877 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
2879 (send_process): No need for setjmp/longjmp any more, since the
2880 SIGPIPE stuff is now gone. Instead, report an error if errno
2882 (record_child_status_change): Now extern. PID and W are now args.
2883 Return void, not bool. All callers changed.
2884 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
2885 Remove. All uses removed. This bug should be fixed now in a
2887 (wait_for_termination_1): Use waitpid rather than sigsuspend,
2888 and record the child status change directly. This avoids the
2889 need to futz with the signal mask.
2890 (process_fatal_action): Move here from emacs.c.
2891 (emacs_sigaction_flags): New function, containing
2892 much of what used to be in emacs_sigaction_init.
2893 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
2894 caught by emacs, to make races less likely.
2895 (deliver_process_signal): Rename from handle_on_main_thread.
2897 (BACKTRACE_LIMIT_MAX): Now at top level.
2898 (thread_backtrace_buffer, threadback_backtrace_pointers):
2900 (deliver_thread_signal, deliver_fatal_thread_signal):
2901 New functions, for more-accurate delivery of thread-specific signals.
2902 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
2903 (deliver_arith_signal): Handle in this thread, not
2904 in the main thread, since it's triggered by this thread.
2905 (maybe_fatal_sig): New function.
2906 (init_signals): New arg DUMPING so that we can be more accurate
2907 about whether we're dumping. Caller changed.
2908 Treat thread-specific signals differently from process-general signals.
2909 Block all signals while handling fatal error; that's safer.
2910 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
2912 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
2913 Ignore SIGPIPE unless batch.
2914 (emacs_backtrace): Output backtrace for the appropriate thread,
2915 which is not necessarily the main thread.
2916 * syssignal.h: Include <stdbool.h>.
2917 (emacs_raise): New macro.
2918 * xterm.c (x_connection_signal): Remove; no longer needed
2919 now that we use sigaction.
2920 (x_connection_closed): No need to mess with sigmask now.
2921 (x_initialize): No need to reset SIGPIPE handler here, since
2922 init_signals does this for us now.
2924 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
2926 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
2927 background rect may be larger (Bug#12245).
2929 2012-09-23 Chong Yidong <cyd@gnu.org>
2931 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
2933 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
2935 * .gdbinit: Just stop at fatal_error_backtrace.
2936 See Stefan Monnier's request in
2937 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
2938 Remove no-longer-used query of system type.
2940 2012-09-22 Chong Yidong <cyd@gnu.org>
2942 * search.c (Freplace_match): Doc fix (Bug#12325).
2944 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
2946 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
2947 (Fline_end_position): Doc fix.
2949 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
2951 2012-09-22 Chong Yidong <cyd@gnu.org>
2953 * dispextern.h (struct image_type): Add new slot, storing a type
2954 initialization function.
2956 * image.c (define_image_type): Call the image initializer function
2957 if it is defined. Arguments and return value changed.
2958 (valid_image_p, make_image): Callers changed.
2959 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
2960 (gif_type, imagemagick_type, svg_type, gs_type):
2961 Add initialization functions.
2962 (Finit_image_library): Call lookup_image_type.
2963 (CHECK_LIB_AVAILABLE): Macro deleted.
2964 (lookup_image_type): Call define_image_type here, rather than via
2965 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
2966 (syms_of_image): Move define_image_type calls for xbm_type and
2967 pbm_type to lookup_image_type.
2969 2012-09-22 Eli Zaretskii <eliz@gnu.org>
2971 * keyboard.c (timer_check_2): Move calculation of 'timers' and
2972 'idle_timers' from here ...
2973 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
2974 lists, to avoid infloops when the timer does something stupid,
2975 like reinvoke itself with the same or smaller time-out.
2978 2012-09-22 Martin Rudalics <rudalics@gmx.at>
2980 * window.c (Fsplit_window_internal): Handle only Qt value of
2981 Vwindow_combination_limit separately.
2982 (Qtemp_buffer_resize): New symbol.
2983 (Vwindow_combination_limit): New default value.
2986 2012-09-22 Eli Zaretskii <eliz@gnu.org>
2988 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
2989 the new overlay string. (Bug#10159)
2991 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
2993 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
2994 or that fprintf is async-signal-safe. POSIX doesn't require
2997 2012-09-22 Chong Yidong <cyd@gnu.org>
2999 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
3002 2012-09-22 Kenichi Handa <handa@gnu.org>
3004 * composite.c (composition_reseat_it): Handle the case that a
3005 grapheme cluster is not covered by a single font (Bug#12352).
3007 2012-09-21 Chong Yidong <cyd@gnu.org>
3009 * image.c (define_image_type): Avoid adding duplicate types to
3010 image_types (Bug#12463). Suggested by Jörg Walter.
3012 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3014 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
3015 (print_load_command_name): Add case LC_DATA_IN_CODE.
3016 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
3018 2012-09-21 Glenn Morris <rgm@gnu.org>
3020 * eval.c (Frun_hook_with_args_until_success)
3021 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
3023 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
3025 * fileio.c (Ffile_selinux_context): Only call freecon when
3026 lgetfilecon succeeded.
3027 (Fset_file_selinux_context): Likewise. (Bug#12444)
3029 2012-09-21 Eli Zaretskii <eliz@gnu.org>
3031 * xdisp.c (try_window_reusing_current_matrix): Under bidi
3032 reordering, locate the cursor by calling set_cursor_from_row; if
3033 that fails, clear the desired glyph matrix before returning a
3034 failure indication to the caller. Fixes leaving garbled display
3035 when fast scrolling with a down-key. (Bug#12403)
3036 (compute_stop_pos_backwards): Fix a typo that caused crashes while
3037 scrolling through multibyte text.
3039 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
3041 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
3042 calling mark_vectorlike since that's the one that marks the window.
3043 (mark_discard_killed_buffers): Mark the final cdr.
3044 * window.h (struct window): Move prev/next_buffers to the
3045 non-standard fields.
3046 * window.c (make_window): Initialize prev/next_buffers manually.
3048 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
3050 Omit unused arg EXPECTED from socket hooks.
3051 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
3052 * nsterm.m (ns_term_init):
3053 * termhooks.h (struct terminal.read_socket_hook):
3054 * w32inevt.c (w32_console_read_socket):
3055 * w32term.c (w32_read_socket):
3056 * xterm.c (XTread_socket):
3057 Omit unused arg EXPECTED. All callers changed.
3058 (store_user_signal_events): Return void, not int, since callers no
3059 longer care about the return value. All uses changed.
3061 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
3063 * w32gui.h (XParseGeometry): Do not declare.
3065 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
3067 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
3068 Ignore 'expected'. See Eli Zaretskii in
3069 <http://bugs.gnu.org/12471#8> (last line).
3071 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
3072 (XParseGeometry): Now static. Substitute extremal values for
3073 values that are out of range.
3075 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
3077 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
3079 * nsfns.m (XParseGeometry): Remove.
3080 (Fx_create_frame): Call x_set_offset to correctly interpret
3081 top_pos in geometry.
3083 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
3084 (Fx_parse_geometry): If there is a space in string, call
3085 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
3087 2012-09-17 Eli Zaretskii <eliz@gnu.org>
3089 * search.c (scan_buffer): Use character positions in calls to
3090 region_cache_forward and region_cache_backward, not byte
3091 positions. (Bug#12196)
3093 * w32term.c (w32_read_socket): Set pending_signals to 1, like
3094 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
3096 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
3097 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
3098 emacs_blocked_malloc, now deleted.
3100 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
3102 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
3103 The workaround was for improving performance on Solaris 2.4, but
3104 is getting in the way now. Emacs will still work if someone is
3105 still running Solaris 2.4 in a museum somewhere; Sun dropped
3106 support for Solaris 2.4 in 2003.
3107 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
3108 * process.c (create_process) [HAVE_WORKING_VFORK]:
3109 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
3110 since Emacs no longer uses vfork on that platform.
3112 2012-09-17 Glenn Morris <rgm@gnu.org>
3114 * emacs.c: Use COPYRIGHT.
3116 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
3118 Remove configure's --without-sync-input option (Bug#12450).
3119 When auditing signal-handling in preparation for cleaning it up,
3120 I found that SYNC_INPUT has race conditions and would be a real
3121 pain to fix. Since it's an undocumented and deprecated
3122 configure-time option, now seems like a good time to remove it.
3123 Also see <http://bugs.gnu.org/11080#16>.
3124 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
3125 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
3126 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3127 (malloc_hysteresis):
3128 (check_depth) [XMALLOC_OVERRUN_CHECK]:
3129 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
3130 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
3131 (dont_register_blocks, bytes_used_when_reconsidered)
3132 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
3133 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
3134 [!SYSTEM_MALLOC && !SYNC_INPUT]:
3135 Remove. All uses removed.
3136 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
3137 implementation, one that depends on whether the new macro
3138 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
3140 * atimer.c (run_timers, handle_alarm_signal):
3141 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
3142 (handle_async_input, process_pending_signals)
3143 (handle_input_available_signal, init_keyboard):
3144 * nsterm.m (ns_read_socket):
3145 * process.c (wait_reading_process_output):
3146 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
3147 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
3149 * xterm.c (XTread_socket):
3151 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
3152 * eval.c (handling_signal): Remove. All uses removed.
3153 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
3154 All uses replaced with the SYNC_INPUT version.
3155 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
3157 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3160 * font.c (Ffont_shape_gstring): Remove unused local.
3162 2012-09-16 Glenn Morris <rgm@gnu.org>
3164 * Makefile.in (clean): No longer run nextstep's clean.
3166 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
3168 (ns-app): Move here from ns.mk, and simplify.
3169 (clean): Simplify nextstep entry.
3170 * ns.mk: Remove file.
3172 2012-09-17 Kenichi Handa <handa@gnu.org>
3174 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
3175 not covert the last few charactes.
3177 2012-09-16 Kenichi Handa <handa@gnu.org>
3179 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
3180 here, but just check the validity of glyphs in the glyph-string.
3182 2012-09-16 Martin Rudalics <rudalics@gmx.at>
3184 * window.c (Fwindow_parameter, Fset_window_parameter):
3185 Accept any window as argument (Bug#12452).
3187 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
3189 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
3190 to ns_term_init to avoid memory leak.
3192 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
3193 explicit retain/release.
3194 (ns_term_init): Only allow one display. Initialize outerpool and
3197 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3199 Port _setjmp fix to POSIXish hosts as well as Microsoft.
3200 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
3201 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
3202 the Microsoft problem in a different way, by altering ../nt/config.nt.
3204 2012-09-15 Eli Zaretskii <eliz@gnu.org>
3219 * w16select.c: Remove inclusion of setjmp.h, as it is now included
3220 by lisp.h. This completes removal of setjmp.h inclusion
3221 erroneously announced in the previous commit. (Bug#12446)
3223 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
3226 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
3227 not defined as a macro. The latter happens on MS-Windows.
3230 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3232 Port better to POSIX hosts lacking _setjmp (Bug#12446).
3233 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
3234 Some instances of '#include <setjmp.h>' removed, if the
3235 only reason for the instance was because "lisp.h" was included.
3236 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
3237 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
3238 and _longjmp with the new symbols. Emacs already uses _setjmp if
3239 available, so this change affects only POSIXish hosts that have
3240 sigsetjmp but not _setjmp, such as some versions of Solaris and
3241 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
3242 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
3243 (png_load_body) [HAVE_PNG]:
3244 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
3245 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
3246 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
3247 since PNG requires jmp_buf. This is the only exception to the
3248 general rule that we now use sys_setjmp and sys_longjmp.
3249 This exception is OK since this code does not change the signal
3250 mask or longjmp out of a signal handler.
3252 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
3254 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3255 Include "syssignal.h", for 'main_thread'.
3257 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
3259 Avoid out-of-range marker position (Bug#12426).
3260 * insdel.c (replace_range, replace_range_2):
3261 Adjust markers before overlays, as suggested by comments.
3262 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
3263 Remove redundant check before calling offset_intervals.
3265 2012-09-14 Martin Rudalics <rudalics@gmx.at>
3267 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
3268 current buffer (Bug#12387).
3270 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
3272 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
3274 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3276 Use a more backwards-compatible timer format (Bug#12430).
3277 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
3278 vector element, not from the 4th, since PSECS is now at the end.
3279 (Fcurrent_idle_time): Doc fix.
3281 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
3283 Function to mark objects and remove killed buffers at once.
3284 * alloc.c (discard_killed_buffers): Rename to ...
3285 (mark_discard_killed buffers) ... new name. Add marking
3286 of remaining objects. Fix comment. Adjust users.
3287 (mark_object): Do not touch frame buffer lists here.
3288 * frame.c (delete_frame): Reset frame buffer lists here.
3290 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3292 Better workaround for GNOME bug when --enable-gcc-warnings.
3293 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
3294 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
3295 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
3297 Simplify SIGIO usage (Bug#12408).
3298 The code that dealt with SIGIO was crufty and confusing, e.g., it
3299 played tricks like "#undef SIGIO" but these tricks were not used
3300 consistently. Simplify mostly by not #undeffing standard symbols,
3301 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
3302 or not as we please) rather than "defined SIGIO" (standard symbol
3303 that we probably shouldn't #undef).
3304 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
3305 Modules that need it can include it.
3306 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
3307 * dispextern.h (ignore_sigio): New decl.
3308 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
3309 unconditionally, since it's now a no-op if !USABLE_SIGIO.
3310 * emacs.c (shut_down_emacs):
3311 * keyboard.c (kbd_buffer_store_event_hold):
3312 Use ignore_sigio rather than invoking 'signal' directly.
3313 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
3315 (FIONREAD, SIGIO): Do not #undef.
3316 (tty_read_avail_input): Use #error rather than a syntax error.
3317 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
3318 for I_PIPE, used by SETUP_SLAVE_PTY.
3319 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
3320 * sysdep.c (croak): Remove; no longer needed. This bit of
3321 temporary code, with Fred N. Fish's comment that it's temporary,
3322 has been in Emacs since at least 1992!
3323 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
3324 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
3325 * syssignal.h (croak): Remove decl.
3326 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
3327 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
3328 now that we're termios-only.
3329 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
3330 * term.c (dissociate_if_controlling_tty): Use #error rather than
3333 Work around GCC and GNOME bugs when --enable-gcc-warnings.
3334 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
3335 to work around GNOME bug 683906.
3336 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
3337 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
3338 This works around GCC bug 54561.
3340 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
3342 More fixes for 'volatile' and setjmp/longjmp.
3343 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
3344 * image.c (struct png_load_context) [HAVE_PNG]: New type.
3345 (png_load_body) [HAVE_PNG]:
3346 (jpeg_load_body) [HAVE_JPEG]:
3347 New function, with most of the old parent function's body.
3348 (png_load) [HAVE_PNG]:
3349 (jpeg_load) [HAVE_JPEG]:
3350 Invoke the new function, to avoid longjmp munging our locals.
3351 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
3352 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
3353 longjmp is passed 2, as the C standard doesn't guarantee this.
3354 Instead, store the failure code into mgr->failure_code.
3356 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
3358 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
3359 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
3360 (syms_of_keyboard): Remove support for unread-command-char.
3362 2012-09-12 Eli Zaretskii <eliz@gnu.org>
3364 * w32proc.c (sys_kill): If PID is our process ID and the signal is
3365 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
3366 violation. (Bug#12426)
3368 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
3370 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
3372 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
3374 * eval.c: Add `inhibit-debugger'.
3375 (Qinhibit_debugger): New symbol.
3376 (call_debugger): Bind it instead of Qdebug_on_error.
3377 (maybe_call_debugger): Test Vinhibit_debugger.
3378 (syms_of_eval): Define inhibit-debugger.
3379 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
3380 (syms_of_xdisp): Remove inhibit-debug-on-message.
3382 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
3384 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
3385 If a nonvolatile local variable is written before a _longjmp to
3386 the frame containing the variable, and is read after the _longjmp,
3387 the value read is indeterminate. Some local variables of type
3388 'struct handler' and 'struct catchtag' are used in this way, so
3389 mark each of their slots as volatile if the slot can be set before
3390 _longjmp and read afterwards.
3391 * lisp.h (struct handler): var and chosen_clause are now volatile.
3392 (struct catchtag): val, next, and pdlcount are now volatile.
3394 * bidi.c (bidi_push_it, bidi_pop_it):
3395 * fns.c (copy_hash_table):
3396 * image.c (define_image_type):
3397 * keyboard.c (kbd_buffer_store_event_hold):
3398 * process.c (Fprocess_send_eof):
3399 * xfaces.c (x_create_gc) [HAVE_NS]:
3400 * xgselect.c (xg_select):
3401 Prefer assignment to memcpy when either will do.
3403 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
3404 Use pointer-to-a-pointer to simplify and avoid a NILP check each
3405 time an item is removed. No need to mark this function 'inline';
3406 the compiler knows better than we do.
3408 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
3410 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
3411 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
3412 to change_frame_size (Bug#12388).
3413 (windowDidResize:): Pass YES to updateFrameSize.
3415 * nsterm.h: Add delay parameter to updateFrameSize.
3417 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
3419 Discard killed buffers from deleted window and frame objects.
3420 This reduces an amount of references to killed buffers and
3421 helps GC to reclaim them faster.
3422 * alloc.c (discard_killed_buffers): New function.
3423 (mark_object): Use it for deleted windows and frames.
3424 (mark_object): If symbol's value is set up for a killed buffer
3425 or deleted frame, restore its global binding.
3426 * data.c (swap_in_global_binding): Add GC notice.
3427 (swap_in_symval_forwarding): Use convenient set_blv_where.
3428 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
3429 * window.h: ... to here.
3431 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
3433 Convenient macro to check whether the buffer is live.
3434 * buffer.h (BUFFER_LIVE_P): New macro.
3435 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
3436 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
3438 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3440 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
3441 composition cases (Bug#12364).
3443 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
3444 overhang of succeeding glyphs overlapping box cursor.
3446 * w32term.c (x_draw_glyph_string): Likewise.
3448 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
3450 Simplify, document, and port floating-point (Bug#12381).
3451 The porting part of this patch fixes bugs on non-IEEE platforms
3452 with frexp, ldexp, logb.
3453 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
3455 * floatfns.c: Simplify discussion of functions that Emacs doesn't
3456 support, by removing commented-out code and briefly listing the
3457 C89 functions excluded. The commented-out stuff was confusing
3458 maintenance, e.g., we thought we needed cbrt but it was commented out.
3459 (logb): Remove decl; no longer needed.
3460 (isfinite): New macro, if not already supplied.
3461 (isnan): Don't replace any existing macro.
3462 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
3463 are present on all C89 platforms.
3464 (Ffrexp): Do not special-case zero, as frexp does the right thing
3466 (Flogb): Do not use logb, as it doesn't have the desired meaning
3467 on hosts that use non-base-2 floating point. Instead, stick with
3468 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
3469 frexp, to avoid getting an unspecified result.
3471 * xdisp.c (Qinhibit_debug_on_message): Now static.
3473 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
3475 * nsterm.m (ns_update_begin): Set clip path to whole view by using
3476 NSBezierPath (Bug#12131).
3478 2012-09-10 Chong Yidong <cyd@gnu.org>
3480 * fns.c (Fdelq, Fdelete): Doc fix.
3482 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
3484 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
3485 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
3487 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
3489 * lisp.h (make_lisp_ptr): New macro to replace XSET.
3490 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
3493 2012-09-09 Eli Zaretskii <eliz@gnu.org>
3495 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
3496 left fringe if the window has a left margin. This avoids leaving
3497 traces of the cursor because its leftmost pixel is not drawn over.
3499 * dispnew.c (update_window_line): When the left margin area of a
3500 screen line is updated, set the redraw_fringe_bitmaps_p flag of
3501 that screen line. (Bug#12277)
3503 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
3505 Assume C89 or later for math functions (Bug#12381).
3506 This simplifies the code, and makes it a bit smaller and faster,
3507 and (most important) makes it easier to clean up signal handling
3508 since we can stop worring about floating-point exceptions in
3509 library code. That was a problem before C89, but the problem
3510 went away many years ago on all practical Emacs targets.
3511 * data.c, image.c, lread.c, print.c:
3512 Don't include <math.h>; no longer needed.
3513 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
3514 might be autoconfigured, as that never happens.
3516 * doprnt.c (DBL_MAX_10_EXP):
3517 * print.c (DBL_DIG):
3518 Remove. C89 or later always defines these.
3519 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
3520 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
3521 (arith_error, domain_error, domain_error2):
3522 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
3523 no longer needed -- we simply return what C returns. All uses removed.
3524 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
3526 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
3527 Remove. All uses expanded, as these macros are no longer used
3528 more than once and are now more trouble than they're worth.
3529 (Ftan): Use tan, not sin / cos.
3530 (Flogb): Assume C89 frexp.
3531 (fmod_float): Assume C89 fmod.
3532 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
3533 (init_floatfns): Remove. All uses removed.
3535 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3537 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
3538 compositeToPoint for OSX < 10.6 (Bug#12390).
3540 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
3542 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
3543 This produces more-accurate results.
3545 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3547 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
3548 changes (Bug#12088).
3550 2012-09-08 Chong Yidong <cyd@gnu.org>
3552 * syntax.c (Fstring_to_syntax): Doc fix.
3554 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3556 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
3557 in the internal border.
3558 (x_set_window_size): Remove static variables and their usage.
3559 (ns_redraw_scroll_bars): Fix NSTRACE arg.
3560 (ns_after_update_window_line, ns_draw_fringe_bitmap):
3561 Remove fringe/internal border adjustment (Bug#11052).
3562 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
3563 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
3564 (ns_fix_rect_ibw): Remove.
3565 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
3566 (ns_dumpglyphs_box_or_relief): Ditto.
3567 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
3569 (ns_dumpglyphs_image): Ditto.
3570 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
3572 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
3573 their usage. Add fringe_extended_p and its use as in other terms.
3574 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
3575 scroll bar was removed.
3576 (updateFrameSize): New function.
3577 (windowDidResize): Move code to updateFrameSize and call it.
3579 * nsterm.h (EmacsView): Add updateFrameSize.
3581 2012-09-07 Chong Yidong <cyd@gnu.org>
3583 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
3585 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
3587 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
3589 More signal-handler cleanup (Bug#12327).
3590 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
3591 Problem introduced when merging patches. Noted by Eli Zaretskii in
3592 <http://bugs.gnu.org/12327#67>.
3593 * floatfns.c: Comment fix.
3594 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
3595 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
3596 and anyway the declaration is harmless even if SIGDANGER is not defined.
3597 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
3598 defined BROKEN_FIONREAD). systty.h formerly did this, but other
3599 source files not surprisingly expected syssignal.h to define, or
3600 not define, SIGIO, and it's cleaner to do it that way, for consistency.
3601 Include <sys/ioctl.h>, for FIONREAD.
3602 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
3603 This eliminates a problem whereby other files mysteriously had
3604 to include "syssignal.h" before including "systty.h" if they
3605 wanted to use "#ifdef SIGIO".
3607 2012-09-07 Eli Zaretskii <eliz@gnu.org>
3609 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
3611 * w32.c (sigemptyset): Empty the set.
3612 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
3614 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
3616 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
3618 * alloc.c (mark_buffer): Revert unsafe marking optimization.
3619 (mark_object): Likewise for frame objects.
3621 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
3623 * syssignal.h (handle_on_main_thread): Always declare,
3624 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
3625 This ports to platforms without HAVE_PTHREAD.
3627 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
3629 Signal-handler cleanup (Bug#12327).
3630 Emacs's signal handlers were written in the old 4.2BSD style with
3631 sigblock and sigmask and so forth, and this led to some
3632 inefficiencies and confusion. Rewrite these to use
3633 pthread_sigmask etc. without copying signal sets around. Also,
3634 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
3635 'signal', and instead use functions that do not attempt to take
3636 over the system name space. This patch causes Emacs's text
3637 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
3638 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
3639 Do not include <signal.h> or "syssignal.h", as these
3640 modules do not use signals.
3641 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
3642 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
3643 Do not include <signal.h>, as "syssignal.h" does that for us now.
3644 * atimer.c (sigmask_atimers): New function.
3645 (block_atimers, unblock_atimers): New functions,
3646 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
3648 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
3649 no longer needed here.
3650 * emacs.c (main): Inspect existing signal handler with sigaction,
3651 so that there's no need to block and unblock SIGHUP.
3652 * sysdep.c (struct save_signal): New member 'action', replacing
3653 old member 'handler'.
3654 (save_signal_handlers, restore_signal_handlers):
3655 Use sigaction instead of 'signal' to save and restore.
3656 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
3657 New function. All users of 'signal' modified to use set_sighandler
3658 if they're writeonly, and to use sys_signal if they're read+write.
3659 (emacs_sigaction_init, forwarded_signal): New functions.
3660 (sys_signal): Remove. All uses replaced by calls to sigaction
3661 and emacs_sigaction_init, or by direct calls to 'signal'.
3662 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
3663 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
3664 all uses replaced by pthread_sigmask etc. calls.
3665 * syssignal.h: Include <signal.h>.
3666 (emacs_sigaction_init, forwarded_signal): New decls.
3667 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
3668 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
3669 (sigmask, sys_sigmask): Remove; no longer needed.
3670 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
3671 (sigblock, sigunblock, sigfree):
3672 (sigsetmask) [!defined sigsetmask]:
3673 Remove. All uses replaced by pthread_sigmask.
3674 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
3675 no longer need to be replaced, and its typical old uses
3676 are now done via emacs_sigaction_init and sigaction.
3677 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
3678 (sys_sigdel): Remove; unused.
3679 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
3681 2012-09-06 Eli Zaretskii <eliz@gnu.org>
3683 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
3684 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
3686 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
3688 Explicitly mark buffer_defaults and buffer_local_symbols.
3689 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
3690 mark_local_symbols here.
3691 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
3692 since special buffers aren't marked here any more.
3693 (allocate_buffer): Chain new buffer with all_buffers here...
3694 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
3696 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
3697 (syms_of_buffer): Remove staticpro of the above.

3701 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
3703 Use bool for booleans in font-related modules.
3704 * font.c (font_intern_prop, font_style_to_value)
3705 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
3706 (generate_otf_features, font_check_otf_features, font_check_otf)
3707 (font_match_p, font_list_entities, font_at):
3708 * fontset.c (fontset_id_valid_p, reorder_font_vector
3709 (fontset_find_font, Fset_fontset_font)
3710 (face_suitable_for_char_p) [0]:
3711 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
3712 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
3713 (m17n_flt_initialized, ftfont_shape_by_flt):
3714 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
3715 * nsfont.m (nsfont_draw):
3716 * w32font.c (w32font_draw):
3717 * w32term.c (x_draw_glyphless_glyph_string_foreground):
3718 Use bool for booleans.
3719 * font.h: Adjust to above API changes.
3720 (struct font, struct font_driver, struct font_driver_list):
3721 Use bool for booleans.
3722 (struct font): Remove useless member encoding_type.
3724 * fontset.c, xftfont.c: Omit unnecessary static decls.
3726 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
3728 * alloc.c (mark_object): Revert window marking code
3729 since it's unsafe for the Fset_window_configuration.
3731 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
3733 Fix race conditions with signal handlers and errno (Bug#12327).
3734 Be more systematic about preserving errno whenever a signal
3735 handler returns, even if it's not in the main thread. Do this by
3736 renaming signal handlers to distinguish between signal delivery
3737 and signal handling. All uses changed.
3738 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
3739 * data.c (deliver_arith_signal): Rename from arith_error.
3740 * dispnew.c (deliver_window_change_signal): Rename from
3741 window_change_signal.
3742 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
3743 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
3744 * keyboard.c (deliver_input_available_signal): Rename from
3745 input_available_signal.
3746 (deliver_user_signal): Rename from handle_user_signal.
3747 (deliver_interrupt_signal): Rename from interrupt_signal.
3748 * process.c (deliver_pipe_signal): Rename from send_process_trap.
3749 (deliver_child_signal): Rename from sigchld_handler.
3750 * atimer.c (handle_alarm_signal):
3751 * data.c (handle_arith_signal):
3752 * dispnew.c (handle_window_change_signal):
3753 * emacs.c (handle_fatal_signal, handle_danger_signal):
3754 * keyboard.c (handle_input_available_signal):
3755 * keyboard.c (handle_user_signal, handle_interrupt_signal):
3756 * process.c (handle_pipe_signal, handle_child_signal):
3757 New functions, with the actual signal-handling code taken from the
3758 original respective signal handlers, sans the sporadic attempts to
3759 preserve errno, since that's now done by handle_on_main_thread.
3760 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
3761 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
3762 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3764 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3765 Move initialization of main_thread to sysdep.c's init_signals.
3766 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
3767 our usage, and simplifies the mainline code.
3768 (record_child_status_change): New static function, as a helper
3769 for handle_child_signal, and with most of the old child handler's
3771 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
3772 (handle_child_signal): Use the above.
3773 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3774 Moved here from emacs.c.
3775 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
3776 code moved here from emacs.c's main function.
3777 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
3778 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
3779 This lets callers save and restore errno properly.
3781 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3783 Remove redundant or unused things here and there.
3784 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
3785 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
3786 * editfns.c (Fcompare_buffer_substrings): Likewise.
3787 * frame.h (struct terminal, struct font_driver_list):
3788 Remove redundant declarations.
3789 * window.h (Qleft, Qright): Likewise.
3791 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3793 Do not mark objects from deleted buffers, windows and frames.
3794 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
3795 (mark_object): Likewise for windows and frames.
3797 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3799 * alloc.c (valid_lisp_object_p): Treat killed buffers,
3800 buffer_defaults and buffer_local_symbols as valid objects.
3801 Return special value to denote them.
3803 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
3805 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
3806 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
3807 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
3808 (file_name_absolute_p, Fsubstitute_in_file_name):
3809 (check_executable, check_writable, Ffile_accessible_directory_p)
3810 (Fset_file_selinux_context, Fdefault_file_modes)
3811 (Finsert_file_contents, choose_write_coding_system)
3812 (Fwrite_region, build_annotations, a_write, e_write)
3814 * filelock.c (boot_time_initialized, get_boot_time)
3815 (get_boot_time_1, lock_file_1, within_one_second):
3816 * floatfns.c (in_float):
3817 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
3818 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
3819 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
3820 * lisp.h (struct Lisp_Hash_Table.cmpfn):
3821 * window.c (compare_window_configurations):
3822 Use bool for booleans.
3823 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
3824 (Fdefault_file_modes): Now mode_t, not int, for modes.
3825 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
3826 (internal_delete_file): Now returns void, not a (boolean) int,
3827 since nobody was looking at the return value.
3828 * lisp.h, window.h: Adjust to above API changes.
3830 * xdisp.c (set_message): Simplify and reindent last change.
3832 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
3834 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
3836 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
3838 * eval.c (call_debugger): Make the function non-static so that we
3839 can call it from set_message.
3841 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
3842 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
3844 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3846 Give more-useful info on a fatal error (Bug#12328).
3847 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
3848 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
3849 of doing the work ourselves.
3850 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
3851 do most of the work.
3852 (fatal_error_backtrace): New function, taken from the guts
3853 of the old fatal_error_signal, but with a new option to output
3855 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
3856 info about the signal than just its number.
3857 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
3858 * sysdep.c: Include <execinfo.h>
3859 (emacs_backtrace): New function, taken partly from the previous
3860 code of the 'die' function.
3861 (emacs_abort): Call fatal_error_backtrace rather than abort.
3863 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
3865 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
3866 eager (load-time) macro-expansion.
3867 * lisp.mk (lisp): Add macroexp.
3869 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3871 Simplify redefinition of 'abort' (Bug#12316).
3872 Do not try to redefine the 'abort' function. Instead, redo
3873 the code so that it calls 'emacs_abort' rather than 'abort'.
3874 This removes the need for the NO_ABORT configure-time macro
3875 and makes it easier to change the abort code to do a backtrace.
3876 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
3877 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
3878 Remove; sysdep.c's emacs_abort now takes its place.
3879 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
3880 'abort' changed to use 'emacs_abort'.
3881 * msdos.c (dos_abort) [defined abort]: Remove; not used.
3882 (abort) [!defined abort]: Rename to ...
3883 (emacs_abort): ... new name.
3884 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
3885 the place of the old 'abort' in emacs.c.
3886 * w32.c, w32fns.c (abort): Do not #undef.
3887 * w32.c (emacs_abort): Rename from w32_abort.
3889 2012-09-04 Eli Zaretskii <eliz@gnu.org>
3891 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
3892 offsets[j].dv, since the y axis of the screen coordinates points
3893 down, while the y axis of the font definition coordinates points
3894 up. This fixes display of Arabic diacritics such as KASRA and
3895 KASRATAN. (Bug#11860)
3897 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3899 Be more systematic about _setjmp vs setjmp.
3900 * alloc.c (test_setjmp, mark_stack):
3901 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
3902 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
3903 (png_load, my_error_exit, jpeg_load):
3904 * process.c (send_process_trap, send_process):
3905 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
3906 The underscored versions are up to 30x faster on some hosts.
3907 Formerly, the code used setjmp+longjmp sometimes and
3908 _setjmp+_longjmp at other times, with no particular reason to
3909 prefer setjmp+longjmp.
3911 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
3913 Fix minor problem found by static checking.
3914 * buffer.c (Fdelete_all_overlays): Return nil.
3916 2012-09-03 Martin Rudalics <rudalics@gmx.at>
3918 * buffer.c (Fdelete_all_overlays): New function.
3920 2012-09-03 Chong Yidong <cyd@gnu.org>
3922 * gtkutil.c: Add extern decl for Qxft.
3924 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
3926 * emacs.c, eval.c: Use bool for boolean.
3927 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
3928 (malloc_using_checking) [DOUG_LEA_MALLOC]:
3929 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
3930 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
3931 (main, decode_env_path, Fdaemon_initialized):
3932 * eval.c (call_debugger, Finteractive_p, interactive_p):
3933 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
3934 (maybe_call_debugger, Fbacktrace):
3935 * process.c (read_process_output, exec_sentinel):
3936 Use bool for booleans.
3937 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
3938 All callers changed.
3939 * eval.c (interactive_p): Omit always-true boolean argument
3940 EXCLUDE_SUBRS_P. All callers changed.
3941 * dispextern.h, lisp.h: Reflect above API changes.
3942 * firstfile.c (dummy): Use the address of 'main', whose signature
3943 won't change, instead of the address of 'initialize', whose
3944 signature just changed from int to bool.
3945 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
3946 * msdos.c (fatal_error_in_progress): ... from here.
3947 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
3949 (redisplay_internal, unwind_redisplay): Simply clear
3950 REDISPLAYING_P when unwinding, instead of saving its previous,
3951 always-false value and then restoring it.
3953 Clean up some extern decls.
3954 Mostly, this hoists extern decls out of .c files and into .h files.
3955 That way, we're more likely to catch errors if the interfaces change.
3956 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
3957 declare xg_mark_data.
3958 * dispextern.h (x_frame_parm_handlers):
3960 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
3961 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
3962 (Qultra_bold, Qoblique, Qitalic):
3963 Move extern decl here from .c file.
3964 * alloc.c (xg_mark_data) [USE_GTK]:
3966 * eval.c (Qlexical_binding):
3967 * fns.c (time) [!HAVE_UNISTD_H]:

3973 * process.c (QCfamily, QCfilter):
3974 * widget.c (free_frame_faces):
3975 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
3976 * xfont.c (x_clear_errors):
3977 * xterm.c (x_frame_parm_handlers):
3978 Remove now-redundant extern decls.
3979 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
3980 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
3982 * xfaces.c: Remove unnecessary static decls.
3983 * xterm.c (updating_frame): Remove decl of nonexistent object.
3985 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
3986 when building globals.h, as the objects that are not built on
3987 this host are not needed to compile C files on this host.
3989 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
3991 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
3993 * frame.h: Add missing prototype for x_wm_set_size_hint.
3995 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

3999 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
4000 (Fsubstitute_command_keys):

4002 (save_excursion_save, save_excursion_restore)
4003 (disassemble_lisp_time, decode_time_components, emacs_nmemftime)

4005 (make_buffer_string, make_buffer_string_both)
4006 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):
4007 * insdel.c (check_markers, gap_left, adjust_markers_for_insert)

4019 * keyboard.c (decode_timer):
4020 Use bool for boolean.
4021 * intervals.h, lisp.h, systime.h: Reflect above API changes.
4022 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
4024 2012-09-02 Chong Yidong <cyd@gnu.org>
4026 * keymap.c (push_key_description): Print M-TAB as C-M-i
4029 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
4031 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
4032 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))
4033 ($(BLD)/editfns.$(O), $(BLD)/ccl.$(O), $(BLD)/chartab.$(O))

4037 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
4039 2012-09-01 Eli Zaretskii <eliz@gnu.org>
4041 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
4042 more than one grapheme cluster passed to the shaper: compute the
4043 offset adjustment values separately for each cluster. (Bug#11860)
4045 * image.c: Restore mistakenly removed inclusion of w32.h. Without
4046 it, GCC doesn't see prototypes of w32_delayed_load, and complains
4047 about implicit conversions from integer to pointer.
4049 2012-09-01 Daniel Colascione <dancol@dancol.org>
4051 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
4052 system used too early.
4054 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
4056 Better seed support for (random).
4057 * emacs.c (main): Call init_random.
4058 * fns.c (Frandom): Set the seed from a string argument, if given.
4059 Remove long-obsolete Gentzel cruft.
4060 * lisp.h, sysdep.c (seed_random): Now takes address and size, not long.
4061 (init_random): New function.
4063 2012-09-01 Daniel Colascione <dancol@dancol.org>
4065 * xterm.h: Add header guards. Declare x_menubar_window_to_frame.
4066 Remove x_set_frame_alpha, x_bitmap_icon, x_make_frame_visible,
4067 x_make_frame_invisible, x_iconify_frame, x_free_frame_resources,
4068 x_wm_set_size_hint, x_query_colors, x_real_positions,
4069 x_set_menu_bar_lines, x_char_width, x_char_height, x_sync,
4070 x_set_tool_bar_lines, x_activate_menubar, and free_frame_menubar,

4161 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
4162 does not become zero (Bug#12234).

4192 (timeout_handler:): Set timer_fired to YES.
4193 (runDialogAt:): Set timer_fired to NO.
4194 Handle click on close button as quit.
4196 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
4197 Add window_closed and button_values. Add void as return value for
4198 add(Button|String|Split). addButton takes int instead of Lisp_Object.
4199 Add process_dialog as new member.
4201 2012-08-28 Eli Zaretskii <eliz@gnu.org>
4203 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it

4339 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
4340 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
4341 not a boolean 'int', since callers never look at the return value.

4344 (emacs_mule_string_char): Remove unused extern decls.
4345 (struct iso_2022_spec, struct coding_system):

4353 Fix spare memory change (Bug#12286).
4354 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
4355 (valid_lisp_object_p): Likewise.
4357 2012-08-27 Martin Rudalics <rudalics@gmx.at>
4359 * window.c (Fset_window_configuration): Record any window's old
4360 buffer if it's replaced (see Bug#8789). If the new current
4361 buffer doesn't appear in the selected window, go to its old
4364 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
4366 Special MEM_TYPE_SPARE to denote reserved memory.
4367 * alloc.c (enum mem_type): New memory type.
4368 (refill_memory_reserve): Use new type for spare memory.
4369 This prevents live_cons_p and live_string_p from incorrect

4372 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
4375 * Makefile.in (.PHONY): versioclean -> versionclean.

4379 * window.c (Qwindow_valid_p, decode_valid_window):
4380 Now static, not extern.
4381 * data.c (Qinterval): Remove; unused.

4398 (map_sub_char_table):
4399 Use bool for boolean.

4401 always 0. All callers changed.
4402 * character.h, charset.h: Adjust to match previous changes.
4403 * character.h (char_printable_p): Remove decl of nonexistent function.
4404 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
4405 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
4406 are all boolean, so make them single-bit bitfields.
4408 * lisp.h (ASET): Remove attempt to detect side effects.
4409 It was meant to be temporary and it often doesn't work,
4410 because when IDX has side effects the behavior of IDX==IDX
4411 is undefined. See Stefan Monnier in
4412 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
4414 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
4416 * lisp.h (functionp): New function (extracted from Ffunctionp).
4417 (FUNCTIONP): Use it.
4418 * eval.c (Ffunctionp): Use it.
4420 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
4422 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
4423 as that's faster and simpler than static storage. Don't bother
4424 with the g_main_context_query overhead if g_main_context_pending
4425 says no events are pending.
4426 (gfds, gfds_size): Remove these static vars.
4427 (xgselect_initialize): Remove; no longer needed.
4428 All uses and decls removed.
4430 * emacs.c (fatal_error_signal_hook): Remove.
4431 All uses removed. This leftover from old code was always 0.
4433 * casefiddle.c, casetab.c, category.c: Use bool for boolean.

4435 * casetab.c (set_case_table):

4446 On assertion failure, print backtrace if available.

4458 Use bool for booleans, instead of int.
4459 * lisp.h, process.h: Adjust prototypes to match above changes.
4460 * callint.c (Fcall_interactively): Don't assume the mark's
4461 offset fits in 'int'.

4473 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
4474 Use bool for booleans, instead of int.
4475 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
4476 since the 1-or-0 return value is always ignored anyway.
4477 (mmap_initialized_p):
4478 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
4479 * buffer.h, lisp.h: Adjust prototypes to match above changes.
4481 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
4483 * bidi.c: Use bool for boolean.
4484 This is a bit more readable, and makes the text segment of bidi.o
4485 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
4486 Presumably it's faster too.

4520 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
4522 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
4523 Otherwise, the compiler complains about (A?B:C) where B is void
4524 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
4525 (fontset_add): Return void, for FONTSET_ADD.
4527 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>

4531 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
4532 (dont_register_blocks) [GC_MALLOC_CHECK]:
4533 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
4534 (check_string_bytes, make_specified_string, memory_full)
4535 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
4536 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
4537 (mark_stack, valid_pointer_p, make_pure_string)
4538 (Fgarbage_collect, survives_gc_p, gc_sweep):
4539 Use bool for booleans, instead of int.
4540 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
4541 Remove unused local.
4542 * alloc.c (PURE_POINTER_P):
4543 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
4544 * editfns.c (Fformat):
4545 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
4547 * fns.c (sweep_weak_table):
4548 * lisp.h (suppress_checking, push_message, survives_gc_p)
4549 (make_pure_string, gc_in_progress, abort_on_gc):
4550 * lread.c (readchar, read1):
4551 * print.c (Fprin1_to_string):
4552 * xdisp.c (push_message):
4553 Use bool for booleans affected directly or indirectly by
4556 Make recently-introduced setters macros.
4557 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
4558 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
4559 (set_fontset_default, set_fontset_fallback): Rename from their
4560 upper-case counterparts, and make them functions rather than macros.
4561 This is more consistent with the other recently-introduced setters.
4562 These don't need to be inline, since they're local.
4564 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
4566 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in

4569 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4571 * lisp.h (vcopy): Use memcpy rather than our own loop.
4572 This fixes a performance regression introduced by the recent
4573 addition of vcopy. This means 'vcopy' will need to be modified
4574 for a copying collector, but that's OK. Also, tighten the
4575 checking in the assertion.
4577 2012-08-21 Eli Zaretskii <eliz@gnu.org>
4579 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
4580 components for RTL text (Bug#11860). Adjust X-OFFSET of each
4581 non-base glyph for the width of the base character, according to
4582 what x_draw_composite_glyph_string_foreground expects.
4583 Generate WADJUST value according to composition_gstring_width's
4584 expectations, to produce correct width of the composed character.
4585 Reverse the sign of the DU offset produced by ScriptPlace.
4587 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4589 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.

4593 Avoid direct writes to contents member of struct Lisp_Vector.
4594 * lisp.h (vcopy): New function to copy data into vector.

4610 buffer to the specified position.
4612 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>

4615 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
4616 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
4617 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
4620 2012-08-20 Glenn Morris <rgm@gnu.org>
4622 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
4623 Don't assume that `ln -f' works.
4625 2012-08-20 Eli Zaretskii <eliz@gnu.org>
4627 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
4628 and later about non-assignments with no effect. See discussion at
4629 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
4632 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
4634 Inline setter functions for Lisp_Objects slots of struct specbinding.
4635 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
4638 2012-08-20 Martin Rudalics <rudalics@gmx.at>
4640 * window.c (select_window): Always make selected window's buffer
4643 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
4645 Use AREF and ASET for docstrings of category tables.
4646 * category.h (CATEGORY_DOCSTRING): Use AREF.
4647 (SET_CATEGORY_DOCSTRING): Use ASET.
4648 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
4650 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
4652 Inline setter functions for hash table members.
4653 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
4654 (set_hash_hash, set_hash_index): Rename with _slot suffix.
4655 (set_hash_key_and_value, set_hash_index, set_hash_next)
4656 (set_hash_hash): New functions.
4657 * charset.c, fns.c: Adjust users.
4659 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
4661 Inline getter and setter functions for per-buffer values.

4665 * buffer.c, data.c: Adjust users.
4667 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
4669 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
4671 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
4673 Rely on <config.h> + <unistd.h> to declare 'environ',
4674 as gnulib does this if the system doesn't.
4675 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
4676 Remove declaration. MS-Windows declares it on stdlib.h which is
4677 included by conf_post.h.
4678 * emacs.c (environ) [DOUG_LEA_MALLOC]:
4679 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
4680 * vm-limit.c: Include <unistd.h>, for 'environ'.
4682 * unexaix.c, unexcoff.c: Include "mem-limits.h".
4683 (start_of_data): Remove decl; mem-limits.h provides it.
4685 * xdisp.c (handle_invisible_prop): Make it a bit faster
4686 and avoid a gcc -Wmaybe-uninitialized diagnostic.
4688 2012-08-19 Chong Yidong <cyd@gnu.org>
4690 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
4693 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>

4698 * data.c (set_internal): Don't use set_blv_found.
4699 (Fkill_local_variable): Likewise.
4701 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
4703 * nsfont.m (ns_ascii_average_width): Ensure the string
4704 ascii_printable is initialized with a null-terminated character
4705 array. Otherwise, it can contain undesired extra characters.
4707 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
4709 port new setting code to Sun C 5.8 2005/10/13
4710 * chartab.c, lisp.h (char_table_set, char_table_set_range):
4711 Return void, not Lisp_Object. Otherwise, the compiler
4712 complains about (A?B:C) where B is void and C is Lisp_Object
4713 when compiling CHAR_TABLE_SET, due to the recent change to
4714 the API of sub_char_table_set_contents.
4716 2012-08-18 Chong Yidong <cyd@gnu.org>
4718 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE

4874 The old version was confusing because it used the same name
4875 'parent' for two different things.

4888 font spec, make the font's attributes take precedence over
4889 directly-specified attributes.
4890 (merge_face_ref): Recognize :font.
4892 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>

4939 Use C-locale tests instead of locale-specific tests for character
4940 types, since we want the ASCII interpretation here, not the
4941 interpretation suitable for whatever happens to be the current locale.

5546 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
5547 * w32.c (init_environment): Change the default values of many
5548 environment variables in dflt_envvars[] to NULL, to avoid pushing
5549 them into environment when they were not already defined.
5550 Remove the code that deletes site-lisp subdirectories from the default
5551 value of EMACSLOADPATH, as it is no longer needed.
5552 (check_windows_init_file): Now external, not static.
5553 Use Vload_path as is, without adding anything, as this function is now
5554 called when Vload_path is already set up.
5556 * w32.h (check_windows_init_file): Add prototype.
5558 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

5564 any, in the DEFALT argument into the root of the Emacs build or
5565 installation tree, as appropriate.
5567 * callproc.c (init_callproc_1): Call decode_env_path instead of
5568 doing its equivalent by hand.
5569 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
5570 the code that sets Vexec_path run on MS-Windows.
5572 * lread.c (init_lread): Add comments to #ifdef's.
5574 * msdos.c (dos_set_window_size, IT_update_begin)

5582 Now constants, not macros.
5584 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
5586 Remove unnecessary casts involving pointers.
5587 These casts are no longer needed now that we assume C89 or later,
5588 since they involve casting to or from void *.

5590 (make_pure_float, make_pure_vector):
5591 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

5600 (x_get_window_property, x_get_window_property_as_lisp_data):
5601 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
5602 Remove unnecessary pointer casts.
5603 * alloc.c (record_xmalloc): New function.
5604 * lisp.h (record_xmalloc): New decl.
5605 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
5606 more like a function. This is because the pointer cast is not
5607 needed. All uses changed.
5608 * print.c (print_string, print_error_message): Avoid length recalc.
5610 Improve fix for macroexp crash with debugging (Bug#12118).
5611 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
5612 ARRAY_MARK_FLAG when checking subscripts, because ASET is
5613 not supposed to be invoked from the garbage collector.
5614 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
5615 (gc_aset): New function, which is like ASET but can be
5616 used in the garbage collector.
5617 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

5629 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
5630 (map_w32_filename): Improve commentary. Simplify switch.
5631 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
5632 headers (most versions of MinGW w32api don't).
5633 (get_security_info, create_symbolic_link)
5634 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
5636 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
5637 in the argument file name.

5641 have the required privileges.
5642 (get_file_security_desc_by_name): Rename from
5643 get_file_security_desc.

5645 with addition of handling of symlinks and support for 'lstat'.
5646 If possible, get file's attributes and security information by
5647 handle, not by name. Produce S_IFLNK bit for symlinks, when
5648 called from 'lstat'.
5649 (stat, lstat): New functions, call 'stat_worker'.
5650 (symlink, readlink, careadlinkat): Rewritten to create and resolve
5651 symlinks when the underlying filesystem supports them.
5653 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
5655 Fix macroexp crash on Windows with debugging (Bug#12118).
5656 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
5657 checking subscripts; problem introduced with the recent
5658 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
5659 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
5660 since it's used in non-static inline functions now.
5662 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
5663 Don't assume buffer size fits in 'int'. Remove unused local.
5665 Use C99-style 'extern inline' if available.

5680 * category.c (CATEGORY_INLINE):
5681 * character.c (CHARACTER_INLINE):
5682 * charset.c (CHARSET_INLINE):
5683 * composite.c (COMPOSITE_INLINE):
5684 * dispnew.c (DISPEXTERN_INLINE):
5685 * sysdep.c (SYSTIME_INLINE):
5686 Define to EXTERN_INLINE, so that the corresponding functions
5687 are compiled into code.
5688 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
5689 (INLINE_HEADER_END): New macros.
5690 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

5710 hard-coding the path separator.
5712 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
5714 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
5715 This how ASET and AREF are supposed to work, and makes
5716 it easier to think about future improvements. See
5717 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
5718 * charset.h (set_charset_attr): New function.

6210 the fix for 12036 would have avoided some of the problems noted in

6222 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
6223 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
6224 not be usable in #if. This simplifies things.
6226 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
6228 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

6233 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
6234 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
6235 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
6236 Adjust to changes in lisp.h and emacs.c, by using

6239 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of

6243 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
6244 instead of gdb_array_mark_flag.
6245 (xboolvector): Get size from $->size, not $->header.size.
6246 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
6247 (xreload, hook-run, hookpost-run): Remove.
6248 * emacs.c: Include <verify.h>.
6249 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
6250 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
6252 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
6253 (gdb_USE_LSB_TAG): New enum constants.
6254 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
6255 Also define these as enum constants, so they're visible to GDB.

6257 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these

6262 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
6263 more convenient now. All uses changed.
6264 (VALMASK) [USE_LSB_TAG]: Also define in this case.

6272 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
6274 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,

7146 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
7147 Prefer snprintf to strncpy.
7148 * nsterm.m (ns_term_init):
7149 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
7150 * nsterm.m (ns_term_init):
7151 Avoid the need for strncpy, by using build_string or
7152 make_unibyte_string directly. Use dtoastr, not snprintf.
7153 * process.c (Fmake_network_process): Diagnose service names that
7154 are too long, rather than silently truncating them or creating
7155 non-null-terminated names.

7172 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
7173 where argument type is known to be a Lisp_Cons.

7186 * lisp.h (make_pure_string): Fix prototype.
7187 (build_pure_c_string): New function, defined as static inline. This
7188 provides a better opportunity to optimize away calls to strlen when
7189 the function is called with compile-time constant argument.
7190 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
7191 argument, adjust users accordingly. Use build_pure_c_string where
7193 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
7194 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
7195 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
7197 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
7199 Avoid calls to strlen in miscellaneous functions.
7200 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
7201 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
7202 * lread.c (openp): Likewise.
7204 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
7206 Avoid calls to strlen in path processing functions.
7207 * fileio.c (file_name_as_directory): Add comment. Change to add
7208 srclen argument and return the length of result. Adjust users
7210 (directory_file_name): Fix comment. Change to add srclen argument,
7211 swap 1st and 2nd arguments to obey the common convention.
7212 Adjust users accordingly.
7213 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
7215 2012-07-10 Glenn Morris <rgm@gnu.org>
7217 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
7218 Move PENDING_OUTPUT_COUNT definition to configure.
7220 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
7221 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
7222 * s/gnu.h (DATA_START): Move definitions to configure.
7224 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
7225 We include usg5-4-common.h, which defines them both.
7227 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
7228 O_RDONLY already includes it).
7230 Stop ns builds setting the EMACSLOADPATH environment variable.
7231 * nsterm.m (ns_load_path): Rename from ns_init_paths.
7232 Now it does not set EMACSLOADPATH, just returns the load-path string.
7233 * nsterm.h: Update accordingly.
7234 * lread.c [HAVE_NS]: Include nsterm.h.
7235 (init_lread) [HAVE_NS]: Use ns_load_path.
7236 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
7238 2012-07-09 Glenn Morris <rgm@gnu.org>
7240 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
7241 since the included bsd-common.h does so.
7243 Stop ns builds setting the EMACSPATH environment variable.
7244 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
7245 (ns_init_paths): Do not set EMACSPATH.
7246 * nsterm.h (ns_exec_path): Add it.
7247 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
7250 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
7252 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
7254 * process.c (wait_reading_process_output): 'waitchannels' was unset
7255 when read_kbd || !NILP (wait_for_cell); fix this.
7257 Add GCC-style 'const' attribute to functions that can use it.
7258 * character.h (char_resolve_modifier_mask):
7259 * keyboard.h (make_ctrl_char):
7260 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
7261 (init_character_once, next_almost_prime, init_fns, init_image)
7262 (flush_pending_output, init_sound):

7267 Declare the dummy function with ATTRIBUTE_CONST.
7268 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
7269 Add decls with ATTRIBUTE_CONST.
7271 Minor improvements to make_formatted_string.
7272 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
7273 where int is good enough, as vsprintf returns an int.
7274 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
7276 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7278 Use make_formatted_string to avoid double length calculation.
7279 * lisp.h (make_formatted_string): New prototype.
7280 * alloc.c (make_formatted_string): New function.
7281 * buffer.c (Fgenerate_new_buffer_name): Use it.
7282 * dbusbind.c (syms_of_dbusbind): Likewise.
7283 * editfns.c (Fcurrent_time_zone): Likewise.
7284 * filelock.c (get_boot_time): Likewise.
7285 * frame.c (make_terminal_frame, set_term_frame_name)
7286 (x_report_frame_params): Likewise.
7287 * image.c (gs_load): Likewise.
7288 * minibuf.c (get_minibuffer): Likewise.

7301 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
7303 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7305 Move marker debugging code under MARKER_DEBUG.
7306 * marker.c (MARKER_DEBUG): Move marker debugging code under
7307 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
7308 for bootstrap with --enable-checking (~3x slowdown reported
7309 by Juanma Barranquero <lekktu@gmail.com>).
7310 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
7312 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
7314 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
7315 See <http://bugs.gnu.org/11825#29>.
7317 2012-07-08 Eli Zaretskii <eliz@gnu.org>
7319 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
7320 has no font, use the frame's font. (Bug#11813)
7321 (display_line): Add commentary about displaying truncation glyphs
7323 (produce_special_glyphs): Move here from term.c.
7325 * term.c (produce_special_glyphs): Move to xdisp.c.
7327 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
7330 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
7332 * xdisp.c (display_line): Avoid warning about implicit declaration
7335 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
7337 * lisp.h: Remove empty conditional.
7339 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
7341 * lread.c (load_path_check): Now static.
7343 Fix some minor --with-ns problems found by static checking.
7344 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
7345 (x_set_font) [!HAVE_X_WINDOWS]:
7346 * image.c (xpm_load_image) [HAVE_NS]:
7347 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
7348 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
7349 Remove unused local.
7350 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
7351 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
7352 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
7353 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
7354 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
7355 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
7356 Fix pointer signedness problem.
7357 * xfaces.c (FRAME_X_FONT_TABLE):
7358 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
7360 2012-07-07 Glenn Morris <rgm@gnu.org>
7362 * lread.c (load_path_check): New function, split from init_lread.
7363 (init_lread): Reorganize. Motivation:
7364 If EMACSLOADPATH is set, check/warn about that rather than the
7365 defaults, which we are not going to use. Hence we can remove
7366 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
7367 Don't warn if site-lisp directories are missing.
7368 If not installed, start from a blank load-path, since
7369 PATH_LOADSEARCH refers to the eventual installation directories.
7371 2012-07-07 Eli Zaretskii <eliz@gnu.org>
7373 Support truncation and continuation glyphs on GUI frames, when
7374 fringes are disabled. (Bug#11832)
7375 * xdisp.c (init_iterator): Get dimensions of truncation and
7376 continuation glyphs even if on GUI frames.
7377 Adjust it->last_visible_x on GUI frames when the left or right fringes,
7378 or both, are absent.
7379 (start_display, move_it_in_display_line_to): Handle the case of a
7380 GUI frame without a fringe to display continuation or truncation
7382 (insert_left_trunc_glyphs): Support GUI frames: make sure
7383 truncation glyphs overwrite enough glyphs from the current line to
7384 have sufficient space in pixels.
7385 (display_line): Support truncation and continuation glyphs on GUI
7386 frames. If some spare pixels are left on the line after inserting
7387 the truncation glyphs, fill that space with a stretch glyph of a
7388 suitably computed width.
7390 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
7391 produce_glyphs, to support GUI sessions.
7393 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
7395 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
7397 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
7399 Do not require float-time's arg to fit in time_t (Bug#11825).
7400 This works better on hosts where time_t is unsigned, and where
7401 float-time is applied to the (negative) difference between two times.
7402 * editfns.c (decode_time_components): Last arg is now double *,
7403 not int *, and means to store all the result as a double, without
7404 worrying about whether the seconds part fits in time_t.
7405 All callers changed.
7406 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
7407 All callers changed.
7408 (Ffloat_time): Do not fail merely because the specified time falls
7409 outside of time_t range.
7411 2012-07-07 Glenn Morris <rgm@gnu.org>
7413 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

7419 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
7420 Update dependencies.
7422 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
7424 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>

7428 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
7429 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
7430 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.

7433 * xfont.c (compare_font_names): Redo to omit the need for casts.
7435 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
7437 * xfns.c (Fx_change_window_property): Doc fix.
7438 * w32fns.c (Fx_change_window_property): Doc fix.
7440 * w32fns.c (Fx_window_property): Accept the same arguments as the
7441 X Windows version. Doc fix.
7442 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
7444 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
7445 Eli Zaretskii <eliz@gnu.org>
7447 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
7448 Windows-specific code from nt/config.nt moved here.
7449 Obsolete settings removed.
7451 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7453 * process.c: Avoid unnecessary calls to gettime.
7454 (wait_reading_process_output): Don't get the time of day
7455 when gobbling data immediately and not waiting, as there's no need
7456 for it in that case. This removes a FIXME.
7458 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
7460 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
7461 is defined (Bug#11768).
7463 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7465 Fix marker debugging code.
7466 * marker.c (byte_char_debug_check): Do not perform the check
7467 if buffer is not multibyte.
7468 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
7469 Call byte_char_debug_check with correct arguments.
7471 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7473 Compile marker debugging code only if ENABLE_CHECKING is defined.
7474 * marker.c (byte_char_debug_check, count_markers):
7475 Use only if ENABLE_CHECKING is defined.
7476 (byte_debug_flag): Remove.
7477 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
7478 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
7480 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7482 Avoid code repetition in marker-related functions.
7483 * marker.c (attach_marker): New function.
7484 (Fset_marker, set_marker_restricted, set_marker_both)
7485 (set_marker_restricted_both): Use it.
7486 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
7487 Consistently rename charno to charpos.
7488 (marker_position): Add eassert.
7489 (marker_byte_position): Convert to eassert.

7508 * window.c (save_window_save): Likewise.
7510 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7512 Do not use Fdelete_overlay in delete_all_overlays
7513 to avoid redundant calls to unchain_overlay.
7514 * buffer.c (drop_overlay): New function.
7515 (delete_all_overlays, Fdelete_overlay): Use it.
7516 * minibuf.c (get_minibuffer): Fix comment.
7518 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7520 Port to OpenBSD 5.1 amd64.
7521 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
7522 This is needed for OpenBSD, and should be harmless on all BSD systems.
7523 Also, include <sys/sysctl.h>, as it should be available on all
7524 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
7525 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
7526 use p_pid member, not kp_proc.pid.
7528 2012-07-06 Glenn Morris <rgm@gnu.org>
7530 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
7532 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
7534 More xmalloc and related cleanup.

7543 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
7545 Omit needless casts involving void * pointers and allocation.
7546 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
7547 as the former is more robust if P's type is changed.
7548 Prefer xzalloc to xmalloc + memset 0.
7549 Simplify malloc-or-realloc to realloc.
7550 Don't worry about xmalloc returning a null pointer.
7551 Prefer xstrdup to xmalloc + strcpy.
7552 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
7554 * keyboard.c (apply_modifiers_uncached): Prefer local array to
7555 alloca of a constant.
7557 2012-07-05 Eli Zaretskii <eliz@gnu.org>
7559 * xdisp.c (display_line): Fix horizontal pixel coordinates when
7560 hscroll is larger than the line width. Fixes long and futile
7561 looping inside extend_face_to_end_of_line (on a TTY) producing
7562 glyphs that are not needed and thrown away.
7564 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>

7592 * xdisp.c (window_hscroll_limited): New function.
7593 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
7594 coordinates when window's hscroll is set to insanely large
7597 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
7599 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

7660 * fileio.c (time_error_value): Check the right error number.
7661 Problem reported by Troels Nielsen in
7662 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
7664 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7666 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
7667 This should be fixed in a better way; see Eli Zaretskii in
7668 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
7669 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
7671 * fileio.c (time_error_value): Rename from special_mtime.
7672 The old name's problems were noted by Eli Zaretskii in
7673 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
7675 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
7676 This variable's comment says Emacs needs at least one GDB-visible
7677 symbol of type enum pvec_type, to work around GDB problems.
7678 The symbol's value doesn't matter.
7680 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
7681 that causes compilation to fail on pre-C99 compilers.
7683 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
7685 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
7686 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
7688 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
7690 * buffer.c (init_buffer_once): Fix initialization of
7691 headers for buffer_defaults and buffer_local_symbols.
7692 Reported by Juanma Barranquero <lekktu@gmail.com>.
7694 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
7696 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
7697 * lisp.h (enum pvec_type): Use fewer bits.
7698 (PSEUDOVECTOR_SIZE_BITS): New constant.
7699 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
7700 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
7701 change in pvec_type.
7702 (PSEUDOVECTOR_TYPEP): New macro.
7703 (TYPED_PSEUDOVECTORP): Use it.
7704 * fns.c (internal_equal): Adapt code to extract pvectype.

7708 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
7709 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
7710 (sweep_vectors): Use it. Use local var `total_bytes' instead of
7711 abusing vector->header.next.nbytes.
7712 (live_vector_p): Use PVEC_TYPE.
7713 (mark_object): Adapt code to extract pvectype. Use switch.
7715 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7717 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
7718 Tighten new eassert a bit.
7720 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
7722 Fix compilation with --enable-gcc-warnings and -O1
7724 * doprnt.c (doprnt): Change type of tem to int, initialize
7725 to avoid compiler warning. Add eassert.
7726 * search.c (simple_search): Initialize match_byte to avoid
7727 compiler warning. Add eassert.
7729 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7731 Avoid weird behavior with large horizontal scrolls.
7732 Without this change, for example, large hscroll values would
7733 mess up Emacs's display on Fedora 15 x86, presumably due to
7734 overflows in int calculations in the display code.
7735 Also, if buffers had long lines, Emacs would freeze.
7736 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
7737 (set_window_hscroll): New function, containing the old guts of
7738 Fset_window_hscroll. Return the clipped value.
7739 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
7740 This avoids the need to check against PTRDIFF_MAX.
7742 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
7744 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
7746 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
7748 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7750 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
7751 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
7752 since GCC 4.4.6 issues a bogus warning for them.
7754 Fix bugs in file timestamp newness comparisons.
7755 * fileio.c (Ffile_newer_than_file_p):
7756 * lread.c (Fload): Use full timestamp resolution of files,
7757 not just the 1-second resolution, so that files that are only
7758 slightly newer still count as newer.
7759 * fileio.c (Ffile_newer_than_file_p): Don't assume file
7760 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
7762 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
7764 * fileio.c: Improve handling of file time marker. (Bug#11852)
7765 (special_mtime): New function.
7766 (Finsert_file_contents, Fverify_visited_file_modtime):
7767 Use it to set special mtime values consistently.
7769 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
7771 * fileio.c (Finsert_file_contents): Properly handle st_mtime
7772 marker for non-existing file. (Bug#11852)
7774 2012-07-03 Glenn Morris <rgm@gnu.org>
7776 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
7777 and did not make it into globals.h).
7779 2012-07-03 Tom Tromey <tromey@redhat.com>
7781 * window.c (Fset_window_margins, Fset_window_fringes)

7817 2012-07-03 Glenn Morris <rgm@gnu.org>
7819 * lisp.h (Frandom): Make it visible to C.
7820 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
7821 buffer for invisible buffers. (Bug#1229)
7823 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7825 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
7826 values which aren't power of 2.
7827 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
7828 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
7831 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
7833 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
7835 * alloc.c (mark_object): Revert part of last patch to use `switch'.
7837 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7839 * alloc.c (allocate_vector_block): Remove redundant
7840 calls to mallopt if DOUG_LEA_MALLOC is defined.
7841 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
7842 avoid calls to mallopt if zero_vector is returned.
7844 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7846 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
7847 is enabled, avoid dereferencing NULL current_sblock if
7850 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7852 Cleanup basic buffer management.
7853 * buffer.h (struct buffer): Change layout to use generic vector
7854 marking code. Fix some comments. Change type of 'clip_changed'
7855 to bitfield. Remove unused #ifndef old.
7856 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
7857 (GET_OVERLAYS_AT): Fix indentation.
7858 (for_each_per_buffer_object_at): New macro.
7859 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

7861 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
7862 * alloc.c (allocate_buffer): Adjust to match new layout of
7863 struct buffer. Fix comment.
7864 (mark_overlay): New function.
7865 (mark_buffer): Use it. Use mark_vectorlike to mark normal
7866 Lisp area of struct buffer.
7867 (mark_object): Use it. Adjust marking of misc objects
7868 and related comments.
7870 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
7872 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
7873 wrapper that is not needed because the wrapped code is a no-op (zero
7874 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
7875 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
7877 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
7879 * alloc.c (mark_buffer): Simplify. Remove prototype.
7880 (mark_object): Add comment. Reorganize marking of vector-like
7881 objects. Use CHECK_LIVE for all vector-like objects except buffers
7882 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
7883 Avoid redundant calls to mark_vectorlike for bool vectors.
7885 2012-06-30 Glenn Morris <rgm@gnu.org>
7887 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
7889 * epaths.in (PATH_SITELOADSEARCH): New.
7890 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
7891 This is rather than relying on --enable-locallisppath elements
7892 having "site-lisp" in their names. (Bug#10208#25, 11658)
7894 2012-06-30 Eli Zaretskii <eliz@gnu.org>
7896 * w32proc.c (sys_select): Accept and ignore one more argument.
7898 * w32.c (emacs_gnutls_pull): Call select with one more argument.
7900 * sysselect.h [DOS_NT]: Don't include sys/select.h.
7901 (pselect) [!MS_DOS]: Redirect to sys_select.
7903 * sysdep.c: Don't include dos.h and dosfns.h.
7905 * process.c (sys_select):
7906 * msdos.c (sys_select): Accept one more argument and ignore it.
7908 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
7909 adapt data types and code to that.
7912 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
7913 which clashes with the gnulib function of the same name.
7915 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
7917 * font.c (font_style_to_value, font_style_symbolic)
7918 (font_prop_validate_style): Add type checks for values in
7921 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
7923 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
7926 2012-06-29 Eli Zaretskii <eliz@gnu.org>
7928 * xdisp.c (try_window_id): Undo last change.
7930 * w32.c (getwd): Adjust commentary about startup_dir.
7931 (init_environment): Always call sys_access, even in non-MSVC
7932 builds. Don't chdir to the directory of the Emacs executable.
7933 This undoes code from 1997 which was justified by the need to
7934 "avoid conflicts when removing and renaming directories". But its
7935 downside was that every relative file name was being interpreted
7936 relative to the directory of the Emacs executable, which can never
7937 be TRT. In particular, it broke sys_access when called with
7938 relative file names.
7939 (sys_access): Map GetLastError to errno.
7941 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
7943 * window.h (struct window): Change type of 'fringes_outside_margins'

7947 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
7950 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
7952 * gnutls.c (emacs_gnutls_handshake):
7953 Add QUIT to make the loop interruptible.
7955 2012-06-29 Glenn Morris <rgm@gnu.org>
7957 * charset.c (init_charset): Make lack of etc/charsets fatal.
7959 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

7963 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

7966 undefined. Convert from xassert to eassert.
7967 * nsmenu.m: Convert from xassert to eassert.
7968 * nsterm.m: Likewise.
7970 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
7972 * editfns.c (region_limit): Clip to narrowing (bug#11770).
7974 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
7976 Avoid integer overflow on scroll-left and scroll-right.
7977 * window.c (HSCROLL_MAX): New macro.
7978 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
7979 overflow when requested scroll falls outside ptrdiff_t range.
7981 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
7983 * window.h (struct window): Change type of 'hscroll',
7984 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
7985 'last_modified' and 'last_overlay_modified' to EMACS_INT.
7986 Adjust users accordingly.
7987 * xdisp.c (try_cursor_movement): Replace type check with eassert.
7988 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
7989 from EMACS_INT to ptrdiff_t.
7990 (make_window): Omit redundant initialization.
7992 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

7996 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>

8065 * alloc.c (allocate_string): Omit intervals initialization.
8066 * alloc.c (make_uninit_multibyte_string): Initialize intervals

8123 * alloc.c: Remove build_string.
8124 * lisp.h: Define build_string as static inline. This provides
8125 a better opportunity to optimize away calls to strlen when the
8126 function is called with compile-time constant argument.
8127 * image.c (imagemagick_error): Convert to build_string.
8128 * w32proc.c (sys_spawnve): Likewise.

8131 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
8133 Use sprintf return value instead of invoking strlen on result.
8134 In the old days this wasn't portable, since some sprintf
8135 implementations returned char *. But they died out years ago and
8136 Emacs already assumes sprintf returns int.
8137 Similarly for float_to_string.
8138 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

8146 Use sprintf or float_to_string result to avoid need to call strlen.
8147 * data.c (Fnumber_to_string):
8148 Use make_unibyte_string, since the string must be ASCII.
8149 * lisp.h, print.c (float_to_string): Now returns int length.
8150 * term.c (produce_glyphless_glyph):
8151 Use sprintf result rather than recomputing it.
8153 Clean out last vestiges of the old HAVE_CONFIG_H stuff.

8322 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
8324 Support higher-resolution time stamps (Bug#9000).
8325 The time stamps are only nanosecond-resolution at the C level,
8326 since that's the best that any real-world system supports now.
8327 But they are picosecond-resolution at the Lisp level, as that's
8328 easy, and leaves room for future OS improvements.
8330 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
8333 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
8334 Don't get current time unless it's needed.
8336 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
8337 now provides it if it's absent.
8338 (start_atimer): Port to higher-res time stamps.
8339 Check for time stamp overflow. Don't get current time more
8340 often than is needed.
8342 * buffer.h (struct buffer): Buffer modtime now has high resolution.
8343 Include systime.h, not time.h.
8344 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
8346 * dired.c: Include stat-time.h.
8347 (Ffile-attributes): File times now have higher resolution.

8350 (struct image): Timestamp now has higher resolution.
8352 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
8353 has at least microseconds now. All uses removed.
8354 (update_frame, update_single_window, update_window, update_frame_1)
8355 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
8356 (duration_to_sec_usec): Remove; no longer needed.
8358 * editfns.c (time_overflow): Now extern.

8364 (decode_time_components, lisp_seconds_argument): New functions.
8365 (make_time): Now static.
8366 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
8367 Report an error if the time is invalid, rather than having the caller
8370 * fileio.c: Include <stat-time.h>
8371 (Fcopy_file): Copy higher-resolution time stamps.
8372 Prefer to set the time stamp via a file descriptor if that works.
8373 (Fset_file_times, Finsert_file_contents, Fwrite_region)
8374 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
8375 (Fvisited_file_modtime, Fset_visited_file_modtime):
8376 Support higher-resolution time stamps.
8378 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
8380 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
8382 * image.c (prepare_image_for_display, clear_image_cache)
8383 (lookup_image): Port to higer-resolution time stamps.
8385 * keyboard.c (start_polling, bind_polling_period):
8386 Check for time stamp overflow.
8387 (read_char, kbd_buffer_get_event, timer_start_idle)
8388 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
8389 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
8390 Port to higher-resolution time stamps. Do not assume time_t is signed.
8391 (decode_timer): New function. Timers are now vectors of length 9,
8392 not 8, to accommodate the picosecond component.
8393 (timer_check_2): Use it.
8395 * nsterm.m (select_timeout, timeval_subtract): Remove.
8396 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
8397 as they're a bit more accurate and handle overflow better.
8398 (ns_select): Change prototype to be compatible with pselect.
8399 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
8400 * nsterm.h (ns_select): Adjust prototype.
8402 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
8403 us-resolution time stamps.
8404 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
8406 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
8408 * lisp.h (time_overflow): New decl.
8409 (wait_reading_process_output): First arg is now intmax_t, not int,
8410 to accommodate larger waits.
8412 * process.h (struct Lisp_Process.read_output_delay):
8413 Now counts nanoseconds, not microseconds.
8414 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
8416 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
8417 (wait_reading_process_output):
8418 Port to ns-resolution time stamps.
8419 (Faccept_process_output, wait_reading_process_output):
8420 Check for time stamp overflow. Do not assume time_t is signed.
8421 (select_wrapper): Remove; we now use pselect.
8422 (Fprocess_attributes): Now generates ns-resolution time stamps.
8424 * sysdep.c: Include utimens.h. Don't include utime.h
8425 or worry about struct utimbuf; gnulib does that for us now.
8426 (gettimeofday): Remove; gnulib provides a substitute.
8427 (make_timeval): New function.
8428 (set_file_times): Now sets ns-resolution time stamps.
8429 New arg FD; all uses changed.
8430 (time_from_jiffies, ltime_from_jiffies, get_up_time)
8431 (system_process_attributes):
8432 Now returns ns-resolution time stamp. All uses changed.
8433 Check for time stamp overflow.
8435 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
8436 provides a substitute now.
8438 * systime.h: Include timespec.h rather than sys/time.h and time.h,
8439 since it guarantees struct timespec.
8440 (EMACS_TIME): Now struct timespec, so that we can support
8441 ns-resolution time stamps.
8442 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
8443 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
8444 (EMACS_USECS): Remove.
8445 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
8446 so multiply the arg by 1000 before storing it.
8447 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
8449 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
8450 Port to ns-resolution time stamps.
8451 (EMACS_TIME_NEG_P): Remove; replaced by....
8452 (EMACS_TIME_SIGN): New macro.
8453 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
8454 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
8455 (set_file_times, make_time, lisp_time_argument): Adjust signature.
8456 (make_timeval, make_lisp_time, decode_time_components): New decls.
8457 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
8458 that it mishandled time_t overflow. You can't compare by subtracting!
8459 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
8460 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
8462 * term.c: Include <sys/time.h>.
8463 (timeval_to_Time): New function, for proper overflow wraparound.

8471 (w32_get_internal_run_time):
8472 Port to higher-resolution Emacs time stamps.
8473 (ltime): Now accepts single 64-bit integer, as that's more convenient
8476 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
8478 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
8479 for compatibility with pselect. Support ns-resolution time stamps.
8481 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
8483 * xselect.c (wait_for_property_change, x_get_foreign_selection):
8484 Check for time stamp overflow, and support ns-resolution time stamps.
8486 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
8487 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
8488 (timeval_subtract): Remove; no longer needed.
8489 (XTflash, XTring_bell, x_wait_for_event):
8490 Port to ns-resolution time stamps. Don't assume time_t is signed.
8492 2012-06-22 Chong Yidong <cyd@gnu.org>
8494 * xdisp.c (x_consider_frame_title): Revert last change.
8496 2012-06-22 Eli Zaretskii <eliz@gnu.org>
8498 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
8499 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
8500 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
8501 staticidx goes up to 1597 out of 1600 = 0x640.)
8503 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
8505 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
8506 Otherwise, the umask might be mistakenly 0 while handling input signals.
8508 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
8510 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

8517 access to `contents' member of Lisp_Vector objects with AREF and ASET
8520 2012-06-19 Chong Yidong <cyd@gnu.org>
8522 * frame.c (delete_frame): When selecting a frame on a different
8523 text terminal, do not alter the terminal's top-frame.

8527 (unwind_format_mode_line): Restore them.
8528 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
8530 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
8531 since tty frames can be explicitly named.
8532 (prepare_menu_bars): Likewise.
8534 * term.c (Ftty_top_frame): New function.
8536 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

8539 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
8540 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
8541 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
8542 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
8543 (METER_1, METER_2): Simplify.
8545 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
8547 * data.c (Fdefalias): Return `symbol' (bug#11686).
8549 2012-06-18 Martin Rudalics <rudalics@gmx.at>
8551 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
8552 gets killed during executing of this function (Bug#11665).
8553 Try to always return Qt when the buffer has been actually killed.
8554 (Vkill_buffer_query_functions): In doc-string say that functions
8555 run by this hook should not change the current buffer.
8557 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
8559 Fix recently-introduced process.c problems found by static checking.
8560 * process.c (write_queue_push, write_queue_pop, send_process):

8563 (send_process): Remove unused local.
8565 2012-06-17 Chong Yidong <cyd@gnu.org>

8568 frames that are not on top.
8570 2012-06-17 Troels Nielsen <bn.troels@gmail.com>
8572 * process.c (make_process): Initialize write_queue.
8573 (write_queue_push, write_queue_pop): New functions.

8577 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
8579 * lisp.h (eassert): Assume C89 or later.
8580 This removes the need for CHECK.
8581 (CHECK): Remove. Its comments about always evaluating its
8582 argument were confusing, as 'eassert' typically does not evaluate
8585 * coding.c (produce_chars): Use ptrdiff_t, not int.
8587 * xterm.c (x_draw_underwave): Check for integer overflow.
8588 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

8773 code works fine either way, and efficiency is not a concern here,
8774 as the union type is for debugging, not for production.
8775 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
8776 Use an inline function on all platforms when using the union type,
8777 since this is simpler and 'static inline' can be used portably

8892 Block-based vector allocation of small vectors.

8921 * doprnt.c (doprnt): Truncate multibyte char correctly.
8922 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
8923 would mishandle a string argument "Xc" if X was a multibyte
8924 character of length 2: it would truncate after X's first byte
8925 rather than including all of X.

8999 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
9000 fields from Lisp_Object to bitfield. Adjust users accordingly.

9008 and 'double' in a couple of places.
9010 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9012 * xdisp.c (handle_stop): Detect whether we have overlay strings
9013 loaded by testing it->current.overlay_string_index to be
9014 non-negative, instead of checking whether n_overlay_strings is
9015 positive. (Bug#11587)

9025 * search.c (search_buffer): Remove calls to

9027 maybe_unify_char, which was the cause of relocation of buffer text
9030 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9032 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
9033 for the duration of call to load_charset, to avoid problems with
9034 callers of maybe_unify_char that access buffer text through C
9037 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
9038 decrement the inhibition flag, instead of just setting or

9044 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.

9048 (gray_bitmap_bits): Remove; no longer needed.

9092 Do not create empty overlays with the evaporate property (Bug#9642).
9093 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
9094 Bug#9642, but explicitly check that the buffer the overlay would
9095 be moved to is live and rearrange lines to make sure that errors
9096 will not put the overlay in an inconsistent state.
9097 (Fdelete_overlay): Cosmetics.
9099 2012-05-28 Eli Zaretskii <eliz@gnu.org>
9101 * w32term.c (my_bring_window_to_top): New function.
9102 (x_raise_frame): Use handle returned by DeferWindowPos, which
9103 could be different from the original one.

9107 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
9108 by calling BringWindowToTop.
9110 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
9111 (WM_EMACS_END): Increase by one.
9113 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
9115 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
9116 This avoids undefined behavior that might cause the eassert
9117 to not catch an out-of-range value.
9119 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
9121 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
9122 Update dependencies.

9131 when referring to sectname field in printf format.
9133 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
9135 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
9136 Only r_alloc_inhibit_buffer_relocation needed to be added;
9137 the others were already declared.
9139 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
9140 before checking whether it's out of range. Put the check inside
9142 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
9144 2012-05-27 Ken Brown <kbrown@cornell.edu>
9146 * callproc.c (Fcall_process): Restore a line that was accidentally
9147 commented out in the 2011-02-13 change (bug#11547).
9149 2012-05-27 Eli Zaretskii <eliz@gnu.org>
9151 * lisp.h [REL_ALLOC]: Add prototypes for external functions
9152 defined on ralloc.c.
9154 * buffer.c [REL_ALLOC]: Remove prototypes of
9155 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
9156 they are now on lisp.h.
9158 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
9160 * search.c (search_buffer): Use it to inhibit relocation of buffer
9161 text while re_search_2 is doing its job, because re_search_2 is
9162 passed C pointers to buffer text. (Bug#11519)
9164 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
9167 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
9168 state after an additional call to move_it_in_display_line_to, keep
9169 the values of it->max_ascent and it->max_descent found for the
9171 (pos_visible_p): Revert the comparison against bottom_y to what it
9172 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
9175 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
9177 Fix coding-related core dumps with gcc -ftrapv.
9178 The code was computing A - B, where A and B are pointers, and B is
9179 random garbage. This can lead to core dumps on platforms that
9180 have special pointer registers, and it also leads to core dumps on
9181 x86-64 when compiled with gcc -ftrapv. The fix is to compute
9182 A - B only when B is initialized properly.
9183 * coding.c (coding_set_source, coding_set_destination): Return void.
9184 (coding_change_source, coding_change_destinations): New functions,
9185 with the old behaviors of coding_set_source and coding_set_destination.
9186 All callers that need an offset changed to use these new functions.
9188 2012-05-26 Glenn Morris <rgm@gnu.org>
9190 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
9192 2012-05-26 Eli Zaretskii <eliz@gnu.org>
9194 Extend mouse support on W32 text-mode console.
9195 * xdisp.c (draw_row_with_mouse_face):
9196 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
9198 * w32console.c: Include window.h.
9199 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
9201 (initialize_w32_display): Initialize mouse-highlight data.
9203 * w32inevt.c: Include termchar.h and window.h.
9204 (do_mouse_event): Support mouse-autoselect-window. When the mouse
9205 moves, call note_mouse_highlight. If help_echo changed, call
9206 gen_help_event to produce help-echo message in the echo area.
9207 Call clear_mouse_face if mouse_face_hidden is set in the mouse
9210 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
9212 * lread.c (read1): Simplify slightly to avoid an overflow warning
9213 with GCC 4.7.0 on x86-64.
9215 2012-05-26 Eli Zaretskii <eliz@gnu.org>
9217 * bidi.c (bidi_mirror_char): Revert last change: an int is
9218 definitely wide enough here.
9220 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
9222 Fix integer width and related bugs (Bug#9874).

9230 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
9232 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9233 (allocate_pseudovector):
9234 Use int, not EMACS_INT, where int is wide enough.
9235 (inhibit_garbage_collection, Fgarbage_collect):
9236 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9237 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
9238 int might not be wide enough.
9239 (bidi_cache_search, bidi_cache_find, bidi_init_it)

9253 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
9254 (Foverlay_recenter, last_overlay_modification_hooks_used)
9255 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
9256 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9257 (validate_region): Omit unnecessary test for b <= e,
9258 since that's guaranteed by the previous test.
9259 (adjust_overlays_for_delete): Avoid pos + length overflow.
9260 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
9261 (report_overlay_modification):
9262 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9263 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
9264 Omit pointer cast, which isn't needed anyway, and doesn't work
9265 after the EMACS_INT -> ptrdiff_t change.
9266 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
9267 * buffer.h: Adjust decls to match defn changes elsewhere.

9272 not int, to avoid needless 32-bit limit on 64-bit hosts.
9273 (exec_byte_code): Use tighter memory-full test, one that checks
9274 for alloca overflow. Don't compute the address of the object just
9275 before an array, as that's not portable. Use EMACS_INT, not
9276 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
9277 * callint.c (Fcall_interactively):
9278 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

9289 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
9290 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9291 (casify_object): Avoid integer overflow when overallocating buffer.
9292 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
9293 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
9294 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
9295 * category.h (CATEGORYP): Don't assume arg is nonnegative.
9296 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
9297 integers are now checked earlier. All uses replaced with XINT.
9299 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9300 For CCL_MapSingle, check that content and value are in int range.
9301 (ccl_driver, Fregister_code_conversion_map):
9302 Check that Vcode_version_map_vector is a vector.
9303 (resolve_symbol_ccl_program): Check that vector header is in range.
9304 Always copy the vector, so that we can check its contents reliably
9305 now rather than having to recheck each instruction as it's being
9306 executed. Check that vector words fit in 'int'.
9307 (ccl_get_compiled_code, Fregister_ccl_program)
9308 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
9309 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
9310 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
9311 contents are in range.
9312 (Fccl_execute_on_string): Check that status is in range.
9313 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
9314 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
9315 Accept and return EMACS_INT, not int, because callers can pass values
9317 (c_string_width, strwidth, lisp_string_width, chars_in_text)

9321 (string_escape_byte8, Fget_byte):
9322 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9323 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
9324 avoid mishandling large integers.
9325 * character.h: Adjust decls to match defn changes elsewhere.

9334 (Fdefine_charset_internal): Check ranges here, more carefully.
9335 Don't rely on undefined behavior with signed left shift overflow.
9336 Don't assume unsigned int fits into fixnum, or that fixnum fits
9337 into unsigned int. Don't require max_code to be a valid fixnum;
9338 that's not true for gb10830 4-byte on a 32-bit host. Allow
9339 invalid_code to be a cons, for the same reason. Require code_offset
9340 to be a character. Avoid int overflow if max_char is close
9342 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
9343 this is intended anyway and avoids some undefined behavior.
9344 (load_charset_map): Pass unsigned, not int, as 2nd arg of
9345 INDEX_TO_CODE_POINT, as that's what it expects.
9346 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
9347 * charset.h (DECODE_CHAR): Return int, not unsigned;
9348 this is what was intended anyway, and it avoids undefined behavior.
9349 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
9350 integer-overflow issues.
9351 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
9352 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
9353 where the argument is EMACS_INT, and this behavior is not intended.
9354 * chartab.c (Fmake_char_table, Fset_char_table_range)
9355 (uniprop_get_decoder, uniprop_get_encoder):
9356 Don't assume fixnum fits in int.
9357 * cmds.c (move_point): New function, that does the gist of
9358 Fforward_char and Fbackward_char, but does so while checking
9359 for integer overflow more accurately.
9360 (Fforward_char, Fbackward_char): Use it.
9361 (Fforward_line, Fend_of_line, internal_self_insert)
9362 (internal_self_insert):
9363 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9364 Fix a FIXME, by checking for integer overflow when calculating
9365 target_clm and actual_clm.

9400 Don't access memory outside of the args array.
9401 (Fdefine_coding_system_internal): Check for charset-id overflow.

10154 (report_error, report_error_1, make_hdr, copy_sym)
10155 (mark_x, adjust_lnnoptrs, unrelocate_symbols):

10159 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10161 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
10162 already have overlays loaded.
10163 (handle_single_display_spec): Before returning without displaying
10164 fringe bitmap, synchronize the bidi iterator with the main display
10165 iterator, by calling iterate_out_of_display_property.
10166 (iterate_out_of_display_property): Detect buffer iteration by
10167 testing that it->string is a Lisp string.
10168 (get_next_display_element): When the current object is exhausted,
10169 and there's something on it->stack, call set_iterator_to_next to
10170 proceed with what's on the stack, instead of returning zero.
10171 (set_iterator_to_next): If called at the end of a Lisp string,
10172 proceed to consider_string_end without incrementing string
10173 position. Don't increment display vector index past the end of

10175 (pos_visible_p): Don't report a position visible when move_it_to
10176 stopped at the last line of window, which happens to be scanned
10177 backwards by the bidi iteration. (Bug#11464)
10179 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10181 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
10182 and right-margin display specs even if the spec is invalid or we
10183 are on a TTY, and thus unable to display on the fringes.
10184 That's because the text with the property will not be displayed anyway,
10185 so we need to signal to the caller that this is a "replacing"
10186 display spec. This fixes display when the spec is invalid or we
10189 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
10191 * unexaix.c (make_hdr): Fix typo in prototype.

10207 2012-05-12 Glenn Morris <rgm@gnu.org>
10209 * Makefile.in (MKDIR_P): New, set by configure.
10210 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
10212 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
10214 Remove unused function hourglass_started.
10215 * dispextern.h (hourglass_started):
10216 * w32fns.c (hourglass_started):
10217 * xdisp.c (hourglass_started): Remove.
10219 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
10221 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
10222 Update dependencies.
10224 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
10226 * xgselect.c (xg_select): Put maxfds+1 into a var.
10227 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
10229 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
10231 2012-05-10 Dave Abrahams <dave@boostpro.com>
10233 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
10234 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
10236 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
10238 * dbusbind.c (xd_registered_buses): New internal Lisp object.
10239 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
10240 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
10241 Initialize xd_registered_buses.
10243 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
10245 Untag more efficiently if USE_LSB_TAG.
10246 This is based on a proposal by YAMAMOTO Mitsuharu in
10247 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
10248 For an admittedly artificial (nth 8000 longlist) benchmark on
10249 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
10250 Emacs's overall text size by 1%.
10251 * lisp.h (XUNTAG): New macro.
10252 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
10253 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
10254 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
10255 * eval.c (Fautoload):
10256 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
10257 * frame.h (XFRAME): Use XUNTAG.
10259 Port recent dbusbind.c changes to 32-bit --with-wide-int.
10260 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
10261 Remove unportable assumptions about print widths of types like
10263 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
10264 intptr_t when converting between pointer and integer, to avoid GCC
10265 warnings about wrong width.
10267 2012-05-09 Eli Zaretskii <eliz@gnu.org>
10269 * w32proc.c (new_child): Force Windows to reserve only 64KB of
10270 stack for each reader_thread, instead of defaulting to 8MB
10271 determined by the linker. This avoids failures in creating
10272 subprocesses on Windows 7, see the discussion in this thread:
10273 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
10275 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
10277 Fix up display of the *Minibuf-0* buffer in the mini window.
10278 * keyboard.c (read_char): Don't clear the echo area if there's no
10280 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
10281 contents of *Minibuf-0*) if there's no message displayed in its stead.
10283 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
10285 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
10288 2012-05-06 Chong Yidong <cyd@gnu.org>
10290 * lisp.mk (lisp): Update.
10292 2012-05-05 Jim Meyering <meyering@redhat.com>
10294 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
10296 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
10298 * data.c (PUT_ERROR): New macro.
10299 (syms_of_data): Use it. Add new error type `user-error'.
10300 * undo.c (user_error): New function.
10301 (Fprimitive_undo): Use it.
10302 * print.c (print_error_message): Adjust print style for `user-error'.
10303 * keyboard.c (user_error): New function.
10304 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
10306 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
10308 Do not limit current-time-string to years 1000..9999.
10309 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
10310 (Fcurrent_time_string): Support any year that is supported by the
10311 underlying localtime representation. Don't use asctime, as it
10312 has undefined behavior for years outside the range -999..9999.
10314 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
10316 Fix race conditions involving setenv, gmtime, localtime, asctime.
10317 Without this fix, interrupts could mess up code that uses these
10318 nonreentrant functions, since setting TZ invalidates existing
10319 tm_zone or tzname values, and since most of these functions return
10320 pointers to static storage.
10321 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
10322 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
10323 Grow the critical sections to include not just invoking
10324 localtime/gmtime, but also accessing these functions' results
10325 including their tm_zone values if any, and any related TZ setting.
10326 (format_time_string): Last arg is now struct tm *, not struct tm **,
10327 so that the struct tm is saved in the critical section.
10328 All callers changed. Simplify allocation of initial buffer, partly
10329 motivated by the fact that memory allocation needs to be outside
10330 the critical section.
10332 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
10334 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
10335 with RESET_INTERVAL.
10337 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
10338 Remove duplicated buffer name initialization.
10340 2012-05-02 Jim Meyering <jim@meyering.net>
10342 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
10344 * xfns.c (x_window): Use xstrdup (Bug#11375).
10346 2012-05-02 Eli Zaretskii <eliz@gnu.org>
10348 * xdisp.c (pos_visible_p): If already at a newline from the
10349 display string before the 'while' loop, don't walk back the glyphs
10350 from it3.glyph_row. Solves assertion violation when the display
10351 string begins with a newline (egg.el). (Bug#11367)
10353 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
10355 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
10358 2012-05-01 Glenn Morris <rgm@gnu.org>
10360 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
10361 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
10362 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
10363 All were removed before 23.1.
10365 * dispnew.c: Remove HAVE_LIBNCURSES test;
10366 it is always true on relevant platforms.
10368 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
10369 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
10371 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
10373 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
10375 * .gdbinit (xpr): Remove checks for no longer existing misc types.
10376 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
10379 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
10381 Do not avoid creating empty evaporating overlays (Bug#9642).
10382 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
10383 That is, do not delete an evaporating overlay if it becomes
10384 empty after its bounds are adjusted to fit within its buffer.
10385 This fix caused other problems, and I'm reverting it until we get
10386 to the bottom of them.
10388 2012-04-27 Chong Yidong <cyd@gnu.org>
10390 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
10392 2012-04-27 Eli Zaretskii <eliz@gnu.org>
10394 * xdisp.c (pos_visible_p): If the window start position is beyond
10395 ZV, start the display from buffer beginning. Prevents assertion
10396 violation in init_iterator when the minibuffer window is scrolled
10397 via the scroll bar.
10399 * window.c (window_scroll_pixel_based): Likewise.
10401 2012-04-27 Chong Yidong <cyd@gnu.org>
10403 * keymap.c (where_is_internal): Doc fix (Bug#10872).
10405 2012-04-27 Glenn Morris <rgm@gnu.org>
10407 * fileio.c (Fcopy_file, Fset_file_selinux_context):
10408 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
10410 2012-04-27 Eli Zaretskii <eliz@gnu.org>
10412 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
10413 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
10415 2012-04-26 Eli Zaretskii <eliz@gnu.org>
10417 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
10418 display element, check also the underlying string or buffer
10419 character. (Bug#11341)
10421 * w32menu.c: Include w32heap.h.
10422 (add_menu_item): If the call to AppendMenuW (via
10423 unicode_append_menu) fails, disable Unicode menus only if we are
10424 running on Windows 9X/Me.
10426 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
10428 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
10429 (xgetint): Add missing shift for LSB tags.
10431 2012-04-24 Martin Rudalics <rudalics@gmx.at>
10433 * keyboard.c (read_char): Don't wipe echo area for select window
10434 events: These might get delayed via `mouse-autoselect-window'
10437 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
10439 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
10440 manipulation of :loaded-from data.
10442 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
10444 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
10445 now a cons (bug#11311).
10447 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
10449 Do not create empty overlays with the evaporate property (Bug#9642).
10450 * buffer.c (Fmove_overlay): Delete an evaporating overlay
10451 if it becomes empty after its bounds are adjusted to fit within
10452 its buffer. Without this fix, in a nonempty buffer (let ((o
10453 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
10454 yields an empty overlay that has the evaporate property, which is
10455 not supposed to happen.
10457 Fix minor GTK3 problems found by static checking.
10458 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
10459 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
10460 (struct _EmacsFixedClass, emacs_fixed_get_type):
10461 Move decls here from emacsgtkfixed.h, since they needn't be public.
10462 (emacs_fixed_get_type): Now static.
10463 (emacs_fixed_class_init): Omit unused local.
10464 (emacs_fixed_child_type): Remove; unused.

10466 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
10467 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
10468 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
10469 (EMACS_FIXED_GET_CLASS): Remove; unused.
10470 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
10472 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
10473 Problem reported by Juanma Barranquero for Windows -Wunused-function.
10475 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
10477 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
10478 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
10479 (__malloc_size_t, __malloc_ptrdiff_t):
10480 Remove. All uses removed, replaced by the definiens if needed,
10481 since we can assume C89 or better now.
10482 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
10483 (protect_malloc_state, align, get_contiguous_space)
10484 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

10489 (special_realloc, _realloc_internal_nolock, _realloc_internal)
10490 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
10491 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
10492 Define using prototypes, not old style.
10493 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
10494 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
10495 (align): Don't assume that signed integer overflow wraps around.
10496 Omit unused local var.
10497 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)

10499 Omit no-longer-needed casts.
10500 (valloc): Use getpagesize, not __getpagesize.
10501 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
10502 (struct hdr): The 'magic' member is now size_t, not unsigned long.
10504 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
10506 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
10508 Move functions from C to Lisp. Make non-blocking method calls
10509 the default. Implement further D-Bus standard interfaces.

10539 (Fdbus_method_return_internal, Fdbus_method_error_internal)
10540 (Fdbus_send_signal, Fdbus_register_service)
10541 (Fdbus_register_signal, Fdbus_register_method): Move to dbus.el.

10554 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
10555 Do not assume ptrdiff_t is the same width as 'int'.
10557 * alloc.c: Handle unusual debugging option combinations.
10558 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
10559 since the two debugging options are incompatible.
10560 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
10562 (mem_init, mem_insert, mem_insert_fixup):
10563 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

10573 (list_system_processes, system_process_attributes) [__FreeBSD__]:
10574 Use Emacs indenting style more consistently. Avoid some casts.
10575 Use 'double' consistently rather than mixing 'float' and 'double'.
10577 2012-04-21 Eduard Wiebe <usenet@pusto.de>
10579 * sysdep.c (list_system_processes, system_process_attributes):

10593 * print.c (print_preprocess): Only check print_depth if print-circle
10595 (print_object): Check for cycles even when print-circle is nil and

10611 * xdisp.c (string_buffer_position_lim): Limit starting position to
10613 (set_cursor_from_row): If called for a mode-line or header-line
10614 row, return zero immediately.
10615 (try_cursor_movement): If inside continuation line, don't back up
10616 farther than the first row after the header line, if any.
10617 Don't consider the header-line row as "partially visible", even if
10618 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
10620 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

10656 New extern decls, to avoid calling undeclared functions.
10657 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
10658 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
10659 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
10660 (NEED_MEM_INSERT): New macro.
10661 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
10662 Remove one incorrect comment and fix another.

10676 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
10677 Remove decls. This fixes an "It stinks!".
10679 * alloc.c (which_symbols): Fix alignment issue / type clash.
10681 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
10683 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
10684 (struct Lisp_Misc_Any): Likewise.
10685 (struct Lisp_Free): Likewise.
10686 * alloc.c (union aligned_Lisp_Symbol): Define.

10696 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
10697 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
10698 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
10699 * s/netbsd.h, s/sol2-6.h:
10700 Remove definition of GC_MARK_STACK, since the default now works.
10701 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
10702 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
10703 no longer the default.
10704 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
10706 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
10708 * lread.c (lisp_file_lexically_bound_p):
10709 Fix hang at ";-*-\n" (bug#11238).
10711 2012-04-14 Eli Zaretskii <eliz@gnu.org>
10713 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row

10727 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
10729 2012-04-11 Daniel Colascione <dancol@dancol.org>
10731 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
10732 against is gone. It's better to use vfork now so that when Cygwin
10733 gains a new, working vfork, we use it automatically (bug#10398).
10735 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

10753 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
10755 * w32.c (w32_delayed_load): Record the full path of the library
10756 being loaded (bug#10424).
10758 2012-04-09 Glenn Morris <rgm@gnu.org>
10760 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
10761 not just in the obarray, before snarfing them. (Bug#11036)
10763 * Makefile.in ($(leimdir)/leim-list.el):
10764 Pass EMACS rather than BUILT_EMACS.
10766 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
10768 * process.c (make_process):
10769 * process.h: Add integer `gnutls_handshakes_tried' member to

10778 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
10779 attempts per process (connection).
10781 2012-04-09 Chong Yidong <cyd@gnu.org>
10783 * eval.c (Fuser_variable_p, user_variable_p_eh)
10784 (lisp_indirect_variable): Functions deleted.
10785 (Fdefvar): Caller changed.
10787 * callint.c (Finteractive, Fcall_interactively):
10788 * minibuf.c (Fread_variable): Callers changed.
10790 2012-04-09 Eli Zaretskii <eliz@gnu.org>
10792 * xdisp.c (set_cursor_from_row): If the display string appears in
10793 the buffer at position that is closer to point than the position
10794 after the display string, display the cursor on the first glyph of
10795 the display string. Fixes cursor display when a 'display' text
10796 property immediately follows invisible text. (Bug#11094)
10798 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
10800 composite.c: use 'double' consistently
10801 * composite.c (get_composition_id): Use 'double' consistently
10802 instead of converting 'float' to 'double' and vice versa; this is
10803 easier to understand and avoids a GCC warning.
10805 2012-04-09 Glenn Morris <rgm@gnu.org>
10807 * Makefile.in: Generate leim-list with bootstrap-emacs, in
10808 preparation for dumping it with emacs. (Bug#4789)

10829 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
10830 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
10831 (mark_memory): Mark Lisp_Objects only if pointers might hide in
10832 objects, as mark_maybe_pointer will catch them otherwise.
10833 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
10834 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

10847 ($(BLD)/xml.$(O)): New dependency list.
10849 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
10850 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
10851 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
10852 [!WINDOWSNT]: New macros.
10853 (init_libxml2_functions, libxml2_loaded_p): New functions.
10854 (parse_region): Call fn_xmlCheckVersion instead of using the macro
10855 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
10856 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
10857 Calls xmlCleanupParser only if libxml2 was loaded (or statically
10859 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
10860 Call init_libxml2_functions before calling libxml2 functions.
10861 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
10863 * emacs.c: Don't include libxml/parser.h.
10864 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
10865 xmlCleanupParser directly.
10867 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
10869 2012-04-07 Eli Zaretskii <eliz@gnu.org>
10871 * indent.c (Fvertical_motion): If there is a display string at
10872 point, use it.vpos to compute how many lines to backtrack after
10873 move_it_to point. (Bug#11133)
10875 2012-04-06 Eli Zaretskii <eliz@gnu.org>
10877 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
10878 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
10879 about subtle differences between FETCH_CHAR* and STRING_CHAR*
10880 macros related to unification of CJK characters. For the details,
10881 see the discussion following the message here:
10882 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
10884 2012-04-04 Chong Yidong <cyd@gnu.org>
10886 * keyboard.c (Vdelayed_warnings_list): Doc fix.
10888 2012-04-01 Eli Zaretskii <eliz@gnu.org>
10890 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

10898 2012-03-31 Eli Zaretskii <eliz@gnu.org>
10900 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
10901 position we get to after a call to move_it_to fails the
10902 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
10903 only if we wind up in a string from display property. (Bug#11063)
10905 * window.c (Fdelete_other_windows_internal): Invalidate the row
10906 and column information about mouse highlight, so that redisplay
10907 restores it after reallocating the glyph matrices. (Bug#7464)
10909 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
10910 string comes from a `display' text property, use the buffer
10911 position of that property as if we actually saw that position in
10913 (move_it_by_lines): Remove the assertion that
10914 "it->current_x == 0 && it->hpos == 0" which can be legitimately
10915 violated when there's a before-string at the beginning of a line.
10918 2012-03-30 Eli Zaretskii <eliz@gnu.org>
10920 * xdisp.c (append_space_for_newline): If the default face was
10921 remapped, use the remapped face for the appended newline.
10922 (extend_face_to_end_of_line): Use the remapped default face for
10923 extending the face to the end of the line.
10924 (display_line): Call extend_face_to_end_of_line when the default
10925 face was remapped. (Bug#11068)
10927 2012-03-29 Eli Zaretskii <eliz@gnu.org>
10929 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

10947 * keyboard.c (Vselection_inhibit_update_commands): New variable.
10948 (command_loop_1): Use it; inhibit selection update for

10955 2012-03-25 Kenichi Handa <handa@m17n.org>
10957 * dispextern.h (struct glyph): Change the bit length of
10958 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
10960 2012-03-24 Eli Zaretskii <eliz@gnu.org>
10962 * s/ms-w32.h (tzname): Include time.h before redirecting to

10967 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
10970 * xterm.c (XTread_socket): Only modify handling_signal if
10971 !SYNC_INPUT. (Bug#11080)
10973 2012-03-23 Eli Zaretskii <eliz@gnu.org>
10975 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
10976 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
10977 when fetching a multibyte character consumes more bytes than
10978 CHAR_BYTES returns, due to unification of CJK characters in
10979 string_char. (Bug#11073)
10981 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
10983 * process.c (wait_reading_process_output): Handle pty disconnect
10984 by refraining from sending oneself a SIGCHLD (bug#10933).
10986 2012-03-22 Chong Yidong <cyd@gnu.org>
10988 * dispextern.h (struct it): New member string_from_prefix_prop_p.

11018 that is not from display property, accept the row as a "cursor
11019 row" if one of the string's character has a non-nil `cursor'
11020 property. Fixes cursor positioning when there are newlines in
11021 overlay strings, e.g. in icomplete.el. (Bug#11035)
11023 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
11025 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
11027 2012-03-12 Chong Yidong <cyd@gnu.org>
11029 * eval.c (inhibit_lisp_code): Rename from
11030 inhibit_window_configuration_change_hook; move from window.c.
11032 * xfns.c (unwind_create_frame_1, Fx_create_frame):
11033 * window.c (run_window_configuration_change_hook)
11034 (syms_of_window): Callers changed.
11036 2012-03-11 Chong Yidong <cyd@gnu.org>

11044 * frame.c (other_visible_frames): Don't assume the selected frame
11045 is visible (Bug#10955).
11047 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
11049 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
11051 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
11053 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
11054 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
11057 2012-03-03 Glenn Morris <rgm@gnu.org>
11059 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
11061 2012-03-02 Eli Zaretskii <eliz@gnu.org>

11064 position past the first glyph_row that ends at ZV. (Bug#10902)
11065 (redisplay_window, next_element_from_string): Fix typos in
11067 (redisplay_window): Pass to move_it_vertically the margin in
11068 pixels, not in screen lines.
11070 2012-03-02 Glenn Morris <rgm@gnu.org>
11072 * buffer.c (buffer-list-update-hook): Doc fix.
11074 2012-02-29 Eli Zaretskii <eliz@gnu.org>
11076 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
11077 push_it before setting up the iterator for the first overlay
11078 string, even if we have an empty string loaded.
11079 (next_overlay_string): If there's an empty string on the iterator
11080 stack, pop the stack. (Bug#10903)
11082 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
11084 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
11085 Suggested by Stefan Monnier in
11086 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
11087 * alloc.c (widen_to_Lisp_Object): New static function.
11088 (mark_memory): Also mark Lisp_Objects by fetching pointer words
11089 and widening them to Lisp_Objects. This would work even if
11090 USE_LSB_TAG is defined and wide integers are used, which might
11091 happen in a future version of Emacs.
11093 2012-02-25 Chong Yidong <cyd@gnu.org>
11095 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
11098 * xselect.c (Fx_selection_exists_p): Doc fix.

11105 requests in kbd_buffer, not just the next one (Bug#8869).
11107 2012-02-23 Chong Yidong <cyd@gnu.org>

11135 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
11136 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
11137 It's useless in that case, and it can cause problems on hosts
11138 that allocate halves of EMACS_INT values separately.
11139 Reported by Dan Horák. Diagnosed by Andreas Schwab in
11140 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
11141 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
11142 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
11143 it avoids undefined behavior on hosts where shifting right by more
11144 than the word width has undefined behavior.
11146 2012-02-19 Chong Yidong <cyd@gnu.org>
11148 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
11149 (Funhandled_file_name_directory, Ffile_name_as_directory)

11191 * window.c (Fdelete_window_internal): Invalidate the mouse
11192 highlight (Bug#9904).

11230 2012-02-07 Glenn Morris <rgm@gnu.org>
11232 * image.c (Fimagemagick_types): Doc fix.
11234 * image.c (imagemagick-render-type): Change it from a lisp object

11270 * character.c (char_width): Return EMACS_INT, not int.
11271 (char_width, c_string_width): Check for overflow when

11298 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to

11305 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
11306 first 2 arguments are identical. This makes inserting large

11761 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
11762 verifies glyph row's hash code--we have just reallocated the

11928 is set, removing the need for VIRT_ADDRESS_VARIES.
11929 (PURE_P): Use a more-efficient implementation that needs just one

11946 behave as if the cursor position were at the window margin.
11948 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
11949 and the cursor position is out of bounds, behave as if the cursor
11950 position were at the window margin. (Bug#10075)
11952 2011-11-18 Chong Yidong <cyd@gnu.org>
11954 * window.c (Fwindow_combination_limit): Make first argument

11976 compute_line_metrics.
11977 (compute_line_metrics): Call row_hash, instead of computing the
11980 * dispnew.c (verify_row_hash): Call row_hash for computing the
11981 hash code of a row, instead of duplicating code from xdisp.c.
11983 * dispextern.h (row_hash): Add prototype.
11985 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
11987 * frame.c (delete_frame): Don't delete the terminal when the last

12036 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
12037 with user-defined heap size. Bump the default size of the temacs

12041 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
12042 current_matrix and desired_matrix. (Bug#9990)
12043 (verify_row_hash) [XASSERTS]: New function.

12090 Avoid some portability problems by eschewing 'extern inline' functions.
12091 The trivial performance wins aren't worth the portability hassles; see
12092 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
12094 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

12143 This is also needed for porting to any host where GC_MARK_STACK is
12144 not GC_MAKE_GCPROS_NOOPS.
12145 (which_symbols): Use it.

12160 * xmenu.c (cleanup_widget_value_tree): New function.
12161 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

12168 (window_box_width, window_box_left, window_box_left_offset)
12169 (window_box_right, window_box_right_offset): Declare extern.
12170 Otherwise, these inline functions do not conform to C99 and
12171 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
12172 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
12173 * intervals.c (adjust_intervals_for_insertion)

12176 (static_offset_intervals): Remove.
12177 (offset_intervals): Rewrite using the old contents of
12178 static_offset_intervals. The old version didn't conform to C99
12179 because an extern inline function contained a reference to an
12180 identifier with static linkage.

12246 official. Move initialization of image_cache_refcount and
12247 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

12493 * editfns.c: Rewrite current-time-zone so that it invokes
12494 the equivalent of (format-time-string "%Z") to get the time zone name.
12495 This fixes a bug when the time zone name contains characters that
12496 need converting from the system time locale to Emacs internal format.
12497 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
12498 that patch fixed format-time-string to do the conversion, but
12499 I forgot to fix current-time-zone.

12501 what Fformat_time_string used to contain.
12502 (Fformat_time_string): Rewrite in terms of format_time_string.
12503 This doesn't change this function's behavior.
12504 (current-time-zone): Rewrite to use format_time_string.
12505 This fixes the bug reported by Michael Schierl in
12506 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
12507 Jason Rumney's 2007-06-07 change worked around this bug, but
12509 * systime.h (tzname, timezone): Remove no-longer-used declarations.
12511 2011-10-19 Eli Zaretskii <eliz@gnu.org>
12513 * xdisp.c (start_display): If the character at POS is displayed
12514 via a display vector, reset IT->current.dpvec_index to zero.
12515 (try_window_reusing_current_matrix): If a line ends in a display
12516 vector or the next line starts in a display vector, continue
12517 redrawing the window even though the character position of
12518 start_row was reached.
12521 2011-10-18 Chong Yidong <cyd@gnu.org>
12523 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
12524 with nobreak-char-display too.
12526 2011-10-18 Eli Zaretskii <eliz@gnu.org>
12528 Fix part 3 of bug#9771.
12529 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
12530 (bidi_resolve_neutral): Don't enter the expensive loop looking for
12531 non-neutral characters if the current character is a paragraph
12532 separator (a.k.a. Newline). This avoids running the same
12533 expensive loop twice, once when we consume the preceding newline
12534 and the other time when the line actually needs to be displayed.
12535 Avoid the loop when we see neutrals on the base embedding level
12536 following a character whose directionality is the same as the
12537 paragraph's. This avoids running the expensive loop when a line
12538 ends in a long sequence of neutrals, like control characters.
12539 Add assertion against STRONG_AL type. Slightly rearrange code
12540 that determines the type of a neutral given the first non-neutral
12542 (bidi_level_of_next_char): Set next_en_pos to zero when
12543 invalidating its info.
12545 2011-10-17 Eli Zaretskii <eliz@gnu.org>
12547 * xdisp.c (push_display_prop): Determine whether to record string
12548 or buffer position by IT->string, not by IT->method. Allow
12549 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
12550 (move_it_vertically_backward): Don't look for character position
12551 immediately after the newline when in a continuation line.
12554 2011-10-15 Martin Rudalics <rudalics@gmx.at>
12556 * window.c (coordinates_in_window): Rewrite and delabelize
12557 vertical border check. (Bug#5357) (Bug#9618)
12559 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
12561 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
12562 errors in XSetWindowBorder (bug#9310).
12564 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
12566 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
12567 avoid crash when xmalloc overrun checking is enabled.
12569 2011-10-13 Eli Zaretskii <eliz@gnu.org>
12571 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
12572 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
12573 cursor motion with <left> and <right> arrow keys.
12575 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
12576 some callers set that themselves.
12578 2011-10-12 Eli Zaretskii <eliz@gnu.org>
12580 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
12581 display string and the previous row comes from the same string and
12582 is empty. (Bug#9739) (Bug#9738)
12584 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
12586 * doc.c (get_doc_string): Encode file name (bug#9735).
12588 2011-10-12 Eli Zaretskii <eliz@gnu.org>
12590 * bidi.c (bidi_level_of_next_char):
12591 * xdisp.c (get_visually_first_element): Remove old incorrect
12592 comments regarding the Unicode Line Separator character.
12594 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
12596 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
12598 * alloc.c (Fgc_status): Do not access beyond zombies array
12599 boundary if nzombies > MAX_ZOMBIES.
12600 * alloc.c (dump_zombies): Add missing format specifier.
12602 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
12604 * xdisp.c (set_cursor_from_row): Simplify conditionals,
12605 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
12607 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
12608 Some packages use them to denote characters with modifiers.
12610 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
12612 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
12613 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
12614 matching a pp-number. Rename parameter var to var1.
12616 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
12618 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
12620 2011-10-08 Glenn Morris <rgm@gnu.org>
12622 * callint.c (Fcall_interactively): Give a more explicit error for the
12623 'c' case with a non-character input. (Bug#8479)
12625 2011-10-08 Eli Zaretskii <eliz@gnu.org>
12627 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
12629 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
12630 lines that are hscrolled on the left.
12632 * dispnew.c (buffer_posn_from_coords): Account for a possible
12633 presence of header-line. (Bug#4426)
12635 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
12637 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
12638 Don't advertise functionality which we discourage or doesn't work.
12640 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
12642 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
12643 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
12644 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
12645 this makes Emacs dump core during garbage collection on rare
12646 occasions. sizeof is obviously inferior to offsetof here, so
12647 stick with offsetof.
12648 (GC_POINTER_ALIGNMENT): New macro.
12649 (mark_memory): Omit 3rd (offset) arg; caller changed.
12650 Don't assume EMACS_INT alignment is the same as pointer alignment.
12652 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
12654 * keyboard.c (read_key_sequence_remapped): New var.
12655 (read_key_sequence): Compute remapping in the right buffer.
12656 (command_loop_1): Use read_key_sequence's remapping directly.
12658 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
12660 * dired.c (file_name_completion): Don't expand file name.
12661 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
12662 before checking file name handler.
12664 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
12665 they've been requested explicitly (bug#9591).
12667 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
12669 * keymap.c (Fsingle_key_description): Use make_specified_string
12670 instead of build_string to build string from push_key_description.
12673 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
12675 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
12676 This fixes a Y2038 bug on 64-bit hosts.
12677 * buffer.c (reset_buffer):
12678 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
12679 (Fclear_buffer_auto_save_failure):
12680 Use 0, not -1, to represent an unset failure time, since time_t
12681 might not be signed.
12683 Remove dependency on glibc malloc internals.
12684 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12685 Move back here from lisp.h, but with their new implementations.
12686 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
12687 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
12688 * charset.c (charset_table_init): New static var.
12689 (syms_of_charset): Use it instead of xmalloc. This removes a
12690 dependency on glibc malloc internals. See Eli Zaretskii's comment in
12691 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
12692 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12693 Move back to alloc.c.
12694 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
12695 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
12697 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
12699 * nsterm.m (windowDidResize): Call x_set_window_size only when
12700 ns_in_resize is true. Otherwise set pixelwidth/height and
12701 call change_frame_size (Bug#9628).
12703 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
12705 Port --enable-checking=all to Fedora 14 x86-64.
12706 * charset.c (syms_of_charset): Also account for glibc malloc's
12707 internal overhead when calculating the initial malloc maximum.
12709 Port --enable-checking=all to Fedora 14 x86.
12710 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12712 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
12713 (overrun_check_realloc, overrun_check_free):
12714 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
12715 That way, xmalloc returns a properly-aligned pointer even if
12716 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
12717 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
12718 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
12719 into account when calculating the initial malloc maximum.
12720 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12721 Move here from alloc.c, so that charset.c can use it too.
12722 Properly align; the old code wasn't right for common 32-bit hosts
12723 when configured with --enable-checking=all.
12724 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
12725 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
12727 2011-09-29 Eli Zaretskii <eliz@gnu.org>
12729 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
12732 2011-09-28 Eli Zaretskii <eliz@gnu.org>
12734 * xdisp.c (compute_display_string_end): If there's no display
12735 string at CHARPOS, return -1.
12737 * bidi.c (bidi_fetch_char): When compute_display_string_end
12738 returns a negative value, treat the character as a normal
12739 character not covered by a display string. (Bug#9624)
12741 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
12743 * lread.c (Fread_from_string): Fix typo in docstring.
12745 2011-09-27 Eli Zaretskii <eliz@gnu.org>
12747 * xdisp.c (handle_invisible_prop): If invisible text ends on a
12748 newline, reseat the iterator instead of bidi-iterating there one
12749 character at a time. (Bug#9610)
12750 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
12751 TO_CHARPOS if the bidi iterator is at base embedding level.
12753 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
12755 * lread.c (readevalloop): Use correct code for NBSP.
12756 (read1): Likewise. (Bug#9608)
12758 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
12760 * dbusbind.c (Fdbus_register_signal): When service is not
12761 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
12763 2011-09-25 Glenn Morris <rgm@gnu.org>
12765 * buffer.c (truncate-lines): Doc fix.
12767 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
12769 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
12770 (Fset_window_next_buffers): Doc fix.
12772 2011-09-24 Glenn Morris <rgm@gnu.org>
12774 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
12776 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
12778 Fix minor problems found by static checking.
12779 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
12780 * indent.c (Fvertical_motion): Fix == vs = typo.
12782 2011-09-24 Eli Zaretskii <eliz@gnu.org>
12784 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
12785 Default value is now t. Doc fix.
12787 * indent.c (Fvertical_motion): Compute and apply the overshoot
12788 logic when moving up, not only when moving down. Fix the
12789 confusing name and values of the it_overshoot_expected variable;
12790 logic changes accordingly. (Bug#9254) (Bug#9549)
12792 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
12793 CHARPOS is covered by a display string which includes newlines.
12794 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
12795 is covered by a display string with embedded newlines.
12797 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
12799 * dbusbind.c (Fdbus_register_signal): Add match rule to
12800 Vdbus_registered_objects_table. (Bug#9581)
12801 (Fdbus_register_method, Vdbus_registered_objects_table):
12804 2011-09-24 Jim Meyering <meyering@redhat.com>
12806 do not ignore write error for any output size
12807 The previous change was incomplete.
12808 While it makes emacs --batch detect the vast majority of stdout
12809 write failures, errors were still ignored whenever the output size is
12810 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
12811 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
12812 && echo FAIL: ignored write error
12813 FAIL: ignored write error
12814 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
12815 && echo FAIL: ignored write error
12816 FAIL: ignored write error
12817 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
12819 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
12821 * emacs.c (Fkill_emacs): In noninteractive mode exit
12822 non-successfully if a write error occurred on stdout. (Bug#9574)
12824 2011-09-21 Eli Zaretskii <eliz@gnu.org>
12826 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
12829 * dispextern.h (struct it): Update the comment documenting what
12832 2011-09-20 Eli Zaretskii <eliz@gnu.org>
12834 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
12835 a display string, extend search for cursor position to end of row.
12836 (find_row_edges): If the row ends in a newline from a display
12837 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
12838 Handle the case of a display string with multiple newlines.
12839 (Fcurrent_bidi_paragraph_direction): Fix search for previous
12840 non-empty line. Fixes confusing cursor motion with arrow keys at
12841 the beginning of a line that starts with whitespace.
12843 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
12845 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
12848 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
12850 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
12851 boolean (Bug#9154).
12853 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12855 * xdisp.c (display_line): Record maximum and minimum buffer
12856 positions even if no glyphs were produced (e.g., by a zero-width
12857 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
12858 buffer positions that will be removed from the glyph row because
12860 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
12861 column is beyond frame width: don't subtract 1 "pixel" when
12862 computing width of the stretch.
12863 (reseat_at_next_visible_line_start): Undo the change made on
12864 2011-09-17 that saved paragraph information and restored it after
12865 the call to `reseat'. (Bug#9545)
12867 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12869 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
12870 and turn window cursor on if cleared (Bug#9415).
12872 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
12874 * search.c (boyer_moore): Take unibyte characters from pattern
12875 literally. (Bug#9458)
12877 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12879 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
12881 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
12883 Fix minor problem found by static checking.
12884 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
12885 initialized, to pacify gcc -Wuninitialized.
12887 * fileio.c: Report proper errno when syscall falls.
12888 (Finsert_file_contents): Save and restore errno,
12889 so that report_file_error outputs the correct diagnostic.
12890 (Fwrite_region) [CLASH_DETECTION]: Likewise.
12892 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12894 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
12896 2011-09-17 Eli Zaretskii <eliz@gnu.org>
12898 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
12899 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
12901 2011-09-17 Eli Zaretskii <eliz@gnu.org>
12903 * xdisp.c (reseat_at_next_visible_line_start): Keep information
12904 about the current paragraph and restore it after the call to reseat.
12906 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
12907 (bidi_find_paragraph_start): Search back for paragraph beginning
12908 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
12909 (bidi_move_to_visually_next): Only trigger paragraph-related
12910 computations when the last character is a newline or at EOB, not
12911 just any NEUTRAL_B. (Bug#9470)
12913 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
12914 truncated lines if point is covered by a display string. (Bug#9524)
12916 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
12918 * xselect.c: Relax test for outgoing X longs (Bug#9498).
12919 (cons_to_x_long): New function.
12920 (lisp_data_to_selection_data): Use it. Correct the test for
12921 short-versus-long data; it was negated. Break out of vector
12922 loop, for efficiency, when a long datum is discovered.
12924 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
12926 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
12928 2011-09-16 Eli Zaretskii <eliz@gnu.org>
12930 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
12931 GCC PR/17406) by declaring this function with external scope.
12933 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
12935 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).

12938 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
12940 * editfns.c (Fformat): Correctly handle text properties on "%%".
12942 2011-09-15 Eli Zaretskii <eliz@gnu.org>
12944 * xterm.c (x_draw_composite_glyph_string_foreground):
12945 * w32term.c (x_draw_composite_glyph_string_foreground):
12946 * term.c (encode_terminal_code):
12947 * composite.c (composition_update_it, get_composition_id):
12948 * xdisp.c (get_next_display_element)
12949 (fill_composite_glyph_string): Add comments about special meaning
12950 of TAB characters in a composition.
12952 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
12954 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
12955 This occurs when processing a multibyte format.
12956 Problem reported by Wolfgang Jenker.
12958 2011-09-15 Johan Bockgård <bojohan@gnu.org>
12960 * xdisp.c (try_cursor_movement): Only check for exact match if
12961 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
12963 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
12965 Remove unused external symbols.
12966 * dispextern.h (calc_pixel_width_or_height): Remove decl.
12967 * xdisp.c (calc_pixel_width_or_height): Now static.
12968 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
12969 * indent.c (check_display_width):
12970 * w32term.c: Fix comment to match code.
12971 * xterm.c, xterm.h (x_catching_errors): Remove.
12973 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
12975 * xselect.c: Use signed conversions more consistently (Bug#9498).
12976 (selection_data_to_lisp_data): Assume incoming selection data are
12977 signed integers, not unsigned. This is to be consistent with
12978 outgoing selection data, which was modified to use signed integers
12979 in as part of the fix to Bug#9196 in response to Jan D.'s comment
12980 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
12981 expects long, not unsigned long.
12983 2011-09-14 Eli Zaretskii <eliz@gnu.org>
12985 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
12986 computation of loop end. Reported by Johan Bockgård
12989 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
12991 * frame.c (Fother_visible_frames_p): Function deleted.
12993 2011-09-12 Eli Zaretskii <eliz@gnu.org>
12995 * indent.c (compute_motion): Process display vector front to back
12996 rather than the other way around. (Bug#2496)
12998 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
13000 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
13002 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
13004 * minibuf.c (Fread_from_minibuffer): Doc fix.
13006 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13008 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
13009 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
13011 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
13013 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
13014 value for non-existent files.
13016 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13018 * fileio.c (Finsert_file_contents): If the file cannot be opened,
13019 set its "size" to -1. This will set the modtime_size field of
13020 the corresponding buffer to -1, which is what
13021 verify-visited-file-modtime expects for files that do not exist.
13024 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
13026 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
13028 * lisp.h: ... from here. push_key_description is no longer
13029 defined in keyboard.c, so its declaration should not be in
13030 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
13031 logically belongs with push_key_description.
13033 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
13035 * buffer.h: Include <sys/types.h> instead of <time.h>.
13036 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
13037 Problem reported by Herbert J. Skuhra.
13039 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
13041 * xml.c (parse_region): Make the parsing work for
13042 non-comment-starting XML files again (bug#9144).
13044 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
13046 * image.c (gif_load): Fix calculation of bottom and right corner.
13049 2011-09-10 Eli Zaretskii <eliz@gnu.org>
13051 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
13052 redisplay in small windows.
13054 2011-09-09 Eli Zaretskii <eliz@gnu.org>
13056 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
13058 2011-09-08 Martin Rudalics <rudalics@gmx.at>
13060 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
13061 Operate on live windows only.
13063 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
13065 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
13067 2011-09-07 Eli Zaretskii <eliz@gnu.org>
13069 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
13070 only under bidi iteration.
13072 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
13074 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
13076 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13078 isnan: Fix porting problem to Solaris 10 with bundled gcc.
13079 Without this fix, the command to link temacs failed due to an
13080 undefined symbol __builtin_isnan. This is because
13081 /usr/include/iso/math_c99.h #defines isnan(x) to
13082 __builtin_isnan(x), but the bundled gcc, which identifies itself
13083 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
13085 * floatfns.c (isnan): #undef, and then #define to a clone of
13087 (Fisnan): Always define, since it's always available now.
13088 (syms_of_floatfns): Always define isnan at the Lisp level.
13090 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13092 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
13094 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13096 * fileio.c: Fix bugs with large file offsets (Bug#9428).
13097 The previous code assumed that file offsets (off_t values) fit in
13098 EMACS_INT variables, which is not true on typical 32-bit hosts.
13099 The code messed up by falsely reporting buffer overflow in cases
13100 such as (insert-file-contents "big" nil 1 2) into an empty buffer
13101 when "big" contains more than 2**29 bytes, even though this
13102 inserts just one byte and does not overflow the buffer.
13103 (Finsert_file_contents): Store file offsets as off_t
13104 values, not as EMACS_INT values. Check for overflow when
13105 converting between EMACS_INT and off_t. When checking for
13106 buffer overflow or for overlap, take the offsets into account.
13107 Don't use EMACS_INT for small values where int suffices.
13108 When checking for overlap, fix a typo: ZV was used where
13109 ZV_BYTE was intended.
13110 (Fwrite_region): Don't assume off_t fits into 'long'.
13111 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
13113 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
13115 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
13117 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13119 sprintf-related integer and memory overflow issues (Bug#9412).
13121 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
13122 (esprintf, exprintf, evxprintf): New functions.
13123 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
13124 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
13125 (modify_event_symbol): Do not assume that the length of
13126 name_alist_or_stem is safe to alloca and fits in int.
13127 (Fexecute_extended_command): Likewise for function name and binding.
13128 (Frecursion_depth): Wrap around reliably on integer overflow.
13129 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
13130 since some callers pass EMACS_INT values.
13131 (Fsingle_key_description): Don't crash if symbol name contains more
13132 than MAX_ALLOCA bytes.
13133 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
13134 (get_minibuffer): Arg is now EMACS_INT, not int.
13135 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
13136 (esprintf, exprintf, evxprintf): New decls.
13137 * window.h (command_loop_level, minibuf_level): Reflect API changes.
13139 * dbusbind.c (signature_cat): New function.
13140 (xd_signature, Fdbus_register_signal):
13141 Do not overrun buffer; instead, report string overflow.
13143 * dispnew.c (add_window_display_history): Don't overrun buffer.
13144 Truncate instead; this is OK since it's just a log.
13146 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
13147 even if the time zone offset is outlandishly large.
13148 Don't mishandle offset == INT_MIN.
13150 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
13151 when creating daemon; the previous buffer-overflow check was incorrect.
13153 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
13154 which has the guts of the old verror function.
13156 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
13157 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
13159 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
13160 (font_unparse_xlfd): Don't blindly alloca long strings.
13161 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
13162 fits in int, when using sprintf. Use single snprintf to count
13163 length of string rather than counting it via multiple sprintfs;
13164 that's simpler and more reliable.
13165 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
13166 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
13167 sprintf, in case result does not fit in int.
13169 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
13170 (fontset_from_font): Print it.
13172 * frame.c (tty_frame_count): Now printmax_t, not int.
13173 (make_terminal_frame, set_term_frame_name): Print it.
13174 (x_report_frame_params): In X, window IDs are unsigned long,
13175 not signed long, so print them as unsigned.
13176 (validate_x_resource_name): Check for implausibly long names,
13177 and don't assume name length fits in 'int'.
13178 (x_get_resource_string): Don't blindly alloca invocation name;
13179 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
13182 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
13183 (xg_check_special_colors, xg_set_geometry):
13184 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
13186 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
13187 Use esprintf, not sprintf, in case result does not fit in int.
13189 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13190 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
13191 it as a large positive number.
13192 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
13193 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13195 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
13196 in case result does not fit in int.
13198 * print.c (float_to_string): Detect width overflow more reliably.
13199 (print_object): Make sprintf buffer a bit bigger, to avoid potential
13200 buffer overrun. Don't assume list length fits in 'int'. Treat
13201 print length of 0 as 0, not as infinity; to be consistent with other
13202 uses of print length in this function. Don't overflow print length
13203 index. Don't assume hash table size fits in 'long', or that
13204 vectorlike size fits in 'unsigned long'.
13206 * process.c (make_process): Use printmax_t, not int, to format
13207 process-name gensyms.
13209 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
13211 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
13212 to avoid potential buffer overrun.
13214 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
13215 if X resource line is longer than 512 bytes.
13217 * xfns.c (x_window): Make sprintf buffer a bit bigger
13218 to avoid potential buffer overrun.
13220 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
13222 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
13224 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13226 Integer overflow fixes for scrolling, etc.
13227 Without these, Emacs silently mishandles large integers sometimes.
13228 For example, "C-u 4294967297 M-x recenter" was treated as if
13229 it were "C-u 1 M-x recenter" on a typical 64-bit host.
13231 * xdisp.c (try_window_id): Check Emacs fixnum range before
13232 converting to 'int'.
13234 * window.c (window_scroll_line_based, Frecenter):
13235 Check that an Emacs fixnum is in range before assigning it to 'int'.
13236 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
13237 values converted from Emacs fixnums.
13238 (Frecenter): Don't wrap around a line count if it is out of 'int'
13239 range; instead, treat it as an extreme value.
13240 (Fset_window_configuration, compare_window_configurations):
13241 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
13243 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
13244 that can exceed INT_MAX. Check that EMACS_INT value is in range
13245 before assigning it to the (possibly-narrower) index.
13246 (match_limit): Don't assume that a fixnum can fit in 'int'.
13248 * print.c (print_object): Use ptrdiff_t, not int, for index that can
13251 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
13252 (Fvertical_motion): Don't wrap around LINES values that don't fit
13253 in 'int'. Instead, treat them as extreme values. This is good
13254 enough for windows, which can't have more than INT_MAX lines anyway.
13256 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
13258 * Require libxml/parser.h to avoid compilation warning.
13260 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
13262 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
13263 since this reportedly can destroy thread storage.
13265 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
13267 * syntax.c (find_defun_start): Update all cache variables if
13268 exiting early (Bug#9401).
13270 2011-08-30 Eli Zaretskii <eliz@gnu.org>
13272 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
13274 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
13275 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
13276 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
13278 * term.c (tty_append_glyph): New function.
13279 (produce_stretch_glyph): Static function and its prototype deleted.
13281 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
13284 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
13286 * image.c (parse_image_spec): Check for nonnegative, not for positive,
13287 when checking :margin (Bug#9390).
13288 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
13289 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
13290 so that the name doesn't mislead. All uses changed.
13292 2011-08-28 Johan Bockgård <bojohan@gnu.org>
13294 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
13297 2011-08-27 Eli Zaretskii <eliz@gnu.org>
13299 * xdisp.c (move_it_to): Don't bail out early when reaching
13300 position beyond to_charpos, if we are scanning backwards.
13301 (move_it_vertically_backward): When DY == 0, make sure we get to
13302 the first character in the line after the newline.
13304 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
13306 * ccl.c: Improve and simplify overflow checking (Bug#9196).
13307 (ccl_driver): Do not generate an out-of-range pointer.
13308 (Fccl_execute_on_string): Remove unnecessary check for
13309 integer overflow, noted by Stefan Monnier in
13310 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
13311 Remove a FIXME that didn't need fixing.
13312 Simplify the newly-introduced buffer reallocation code.
13314 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
13316 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
13318 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
13320 Integer and memory overflow issues (Bug#9196).
13322 * doc.c (get_doc_string): Rework so that
13323 get_doc_string_buffer_size is the actual buffer size, rather than
13324 being 1 less than the actual buffer size; this makes xpalloc more
13327 * image.c (x_allocate_bitmap_record, cache_image):
13328 * xselect.c (Fx_register_dnd_atom):
13329 Simplify previous changes by using xpalloc.
13331 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
13332 since either will do and ptrdiff_t is convenient with xpalloc.
13334 * charset.c (charset_table_size)
13335 (struct charset_sort_data.priority): Now ptrdiff_t.
13336 (charset_compare): Don't overflow if priorities differ greatly.
13337 (Fsort_charsets): Don't assume list length fits in int.
13338 Check for size-calculation overflow when allocating sort data.
13339 (syms_of_charset): Allocate an initial charset table that is
13340 just under 64 KiB, to avoid problems with glibc malloc and mmap.
13342 * cmds.c (internal_self_insert): Check for size-calculation overflow.
13344 * composite.h (struct composition.glyph_len): Now int, not unsigned.
13345 The actual value is always <= INT_MAX, and leaving it unsigned made
13346 overflow checking harder.
13348 * dispextern.h (struct glyph_matrix.rows_allocated)
13349 (struct face_cache.size): Now ptrdiff_t, for convenience in use
13350 with xpalloc. The values are still always <= INT_MAX.
13352 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
13354 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
13355 (SAFE_NALLOCA): New macro.
13357 * region-cache.c (struct boundary.pos, find_cache_boundary)
13358 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
13359 (set_cache_region, invalidate_region_cache)
13360 (revalidate_region_cache, know_region_cache, region_cache_forward)
13361 (region_cache_backward, pp_cache):
13362 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
13363 so that ptrdiff_t * can be passed to xpalloc.
13364 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
13365 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
13366 (pp_cache): Don't assume cache_len fits in int.
13367 * region-cache.h: Adjust extern decls to match.
13369 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
13370 EMACS_INT, since either will do, for xpalloc.
13372 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
13373 (xnmalloc, xnrealloc, xpalloc): New functions.
13375 * bidi.c (bidi_shelve_header_size): New constant.
13376 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
13377 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
13379 * bidi.c (bidi_cache_shrink):
13380 * buffer.c (overlays_at, overlays_in, record_overlay_string)
13382 Don't update size of array until after memory allocation succeeds,
13383 because xmalloc/xrealloc may not return.
13384 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
13385 now that we have proper integer overflow checking.
13386 (record_overlay_string, overlay_strings): Catch overflows when
13387 calculating size of overlay_str_buf.
13389 * callproc.c (Fcall_process): Check for size overflow when
13390 calculating size of args2.
13391 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
13392 Normally we prefer signed values, but sticking with ptrdiff_t would
13393 require adding more-complicated checks.
13395 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
13396 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
13397 Redo buffer-overflow calculations to avoid integer overflow.
13398 Add a FIXME comment where memory seems to be over-allocated.
13400 * character.c (Fstring): Check for size-calculation overflow.
13402 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
13403 unnecessary integer overflow. Check for size overflow.
13404 (encode_coding_object): Don't update size until xmalloc succeeds.
13406 * composite.c (get_composition_id): Check for overflow in glyph
13407 length calculations.
13409 Integer and memory overflow fixes for display code.
13410 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
13411 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
13412 (scrolling_window): Check for overflow in size calculations.
13413 (line_draw_cost, realloc_glyph_pool, add_row_entry):

13436 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
13438 * emacs.c (main): Do not reallocate argv, since there is a null at
13439 the end that can be overwritten, and this way there's no need to
13440 worry about size-calculation overflow.
13441 (sort_args): Check for size-calculation overflow.

13570 (X_LONG_MIN): New macros.
13571 Use them to make the following changes clearer.
13572 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.

13574 future maintainers not to raise the value too much later.
13575 (SELECTION_QUANTUM): Remove, replacing with ...
13576 (selection_quantum): ... new function, which avoids overflow.
13578 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
13579 assumption that selection length fits in 'int'.

13596 Don't store size until memory allocation succeeds.
13597 (x_get_window_property): Plug memory leak on memory exhaustion.
13598 Don't double-block input; malloc is safe here. Don't assume 2**34
13599 - 4 fits in unsigned long. Add an xassert to check
13600 XGetWindowProperty overflow. Be more careful about overflow
13601 calculations, and distinguish size from memory overflow better.

13608 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
13609 result parameters unless successful. Rely on cons_to_unsigned
13610 to report problems with elements; the old code wasn't right anyway.

13645 * lisp.h (hash_lookup, hash_put):
13646 * minibuf.c (Ftest_completion):
13647 Use ptrdiff_t for hash table indexes, not int (which is too
13648 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on

13681 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
13682 (x_send_scroll_bar_event): Likewise. Check that the size does not
13683 exceed limits imposed by XClientMessageEvent, as well as the usual
13684 ptrdiff_t and size_t limits.
13686 * keyboard.c: Overflow, signedness and related fixes.
13687 (make_lispy_movement): Use same integer type in forward decl
13688 that is used in the definition.

13690 Change bufsize argument back to int, undoing my 2011-03-30 change.
13691 We prefer signed types, and int is wide enough here.
13692 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
13693 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
13694 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
13695 length, not size_t. Use ptrdiff_t for index, not int.
13696 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
13697 possibility of integer overflow.

13725 Prefer int to unsigned where either will do.
13726 (tiff_handler): New function, combining the cores of the
13727 old tiff_error_handler and tiff_warning_handler.

13729 stack buffer overflows. It uses only the features of vsnprintf
13730 that are common to both POSIX and native Microsoft.
13731 (tiff_error_handler, tiff_warning_handler): Use it.
13732 (tiff_load, gif_load, imagemagick_load_image):
13733 Don't assume :index value fits in 'int'.

13736 the integer types that MagickCropImage accepts. Don't assume
13737 Vimagemagick_render_type has a nonnegative value. Don't assume

13753 (handle_single_display_spec): If the display spec is of the form
13754 `(space ...)', and specifies display in the text area, return 2
13756 (try_cursor_movement): Check for the need to scroll more
13757 accurately, and prefer exact match for point under bidi.
13758 Don't advance `row' beyond the last row of the window.

13779 positioning on the newline at EOL of R2L text within L2R
13780 paragraph, and vice versa.
13781 (try_cursor_movement): Check continued rows, in addition to
13782 continuation rows. Fixes unwarranted scroll when point enters a
13783 continued line of R2L text within an L2R paragraph, or vice versa.
13784 (cursor_row_p): Consider the case of point being equal to
13785 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
13786 from the end of a short line to the beginning of a continued line
13787 of R2L text within L2R paragraph.

13814 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
13815 instead of CHAR_TO_BYTE. Fixes a crash when a completion
13816 candidate is selected by the mouse, and that candidate has a
13817 composed character under the mouse.
13819 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
13820 coordinates reported by pos-visible-in-window-p for a composed

13830 consider it a hit if to_charpos is anywhere in the range of the
13831 composed buffer positions.
13833 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
13835 * image.c (gif_load): Don't assume that each subimage has the same
13836 dimensions as the base image. Handle disposal method that is
13837 "undefined" by the gif spec (Bug#9335).
13839 2011-08-20 Chong Yidong <cyd@stupidchicken.com>

13844 2011-08-19 Eli Zaretskii <eliz@gnu.org>
13846 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
13847 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
13848 from an Org mode buffer to a Speedbar frame.
13850 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
13851 a composition, take its buffer position from IT->cmp_it.charpos.
13852 Fixes cursor positioning at the beginning of a line that begins
13853 with a composed character.
13855 2011-08-18 Eli Zaretskii <eliz@gnu.org>
13857 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
13858 character bidirectional type, use STRONG_L instead. Fixes crashes
13859 in a buffer produced by `describe-categories'.
13861 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
13862 members before the level stack, so they would be saved and
13863 restored when copying iterator state. Fixes incorrect reordering
13864 around TABs covered by display properties.
13866 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
13868 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

13873 (internal_condition_case_2, internal_condition_case_n):
13874 Remove unnecessary aborts (Bug#9081).
13876 2011-08-17 Eli Zaretskii <eliz@gnu.org>
13878 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
13879 has no `load' handler, try opening the file locally. (Bug#9311)
13881 2011-08-16 Ken Brown <kbrown@cornell.edu>
13883 * gmalloc.c: Expand comment.
13885 2011-08-16 Eli Zaretskii <eliz@gnu.org>

13901 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
13902 in the static heap.
13903 [CYGWIN] (special_realloc): New function.
13904 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
13905 requests to realloc storage in the static heap.

13920 * chartab.c: Improve commentary for the uniprop_table API.
13922 * bidi.c (bidi_paragraph_init): Support zero value of
13923 bidi_ignore_explicit_marks_for_paragraph_level.
13924 (bidi_initialize): Use uniprop_table instead of including
13925 biditype.h and bidimirror.h.
13927 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
13928 coordinates of the iterator when restoring from ppos_it.

13938 * xdisp.c (move_it_in_display_line_to): Don't invoke
13939 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
13940 ppos_it. Fixes vertical cursor motion when line beginning is
13941 covered by an image. (Bug#9296)
13943 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
13945 * nsterm.h (ns_run_ascript): Declare.
13946 (NSAPP_DATA2_RUNASSCRIPT): Define.
13948 * nsfns.m (as_script, as_result, as_status): New static variables.
13949 (ns_run_ascript): New function.
13950 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
13951 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
13952 the event loop. Get status from as_status (Bug#7276).
13954 * nsterm.m (sendEvent): If event is NSApplicationDefined and
13955 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
13956 the event loop (Bug#7276).
13958 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
13960 * gnutls.c (QCgnutls_bootprop_priority)
13961 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
13962 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
13963 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
13964 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
13965 (QCgnutls_bootprop_verify_hostname_error)
13966 (QCgnutls_bootprop_callbacks_verify): Rename from
13967 Qgnutls_bootprop_..., all uses changed.

13981 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
13982 (Fnetwork_interface_list): Allocate in increments of bytes instead
13983 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
13984 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
13986 (struct ifflag_def): notrailers is smart on OSX.
13987 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
13988 Get hardware address with getifaddrs if available.
13990 2011-08-12 Eli Zaretskii <eliz@gnu.org>
13992 * xdisp.c (iterate_out_of_display_property): xassert that
13993 IT->position is set to within IT->object's boundaries. Break from
13994 the loop as soon as EOB is reached; avoids infloops in redisplay
13995 when IT->position is set up wrongly due to some bug.
13996 Set IT->current to match the bidi iterator unconditionally.
13997 (push_display_prop): Allow GET_FROM_STRING as IT->method on
13998 entry. Force push_it to save on the stack the current
13999 buffer/string position, to be restored by pop_it. Fix flags in
14000 the iterator structure wrt the object coming from a display
14001 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
14002 properties. (Bug#9284)
14004 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
14006 * fontset.c (fontset_get_font_group): Add proper type checks.

14019 no-display-properties-and-no-overlays under bidi display.
14020 Set disp_pos in the bidi iterator to avoid searches for display
14021 properties and overlays.
14023 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
14025 * editfns.c (Fset_time_zone_rule): Document relationship with the

14031 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
14033 * composite.c (autocmp_chars): Don't reset point. That is done by
14034 restore_point_unwind (Bug#5984).
14036 2011-08-07 Juri Linkov <juri@jurta.org>
14038 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
14039 to show the arg `TIME' instead of `TIMEVAL'.
14041 2011-08-06 Eli Zaretskii <eliz@gnu.org>
14043 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
14044 display property strides EOL and includes a newline, as in
14045 longlines-mode. (Bug#9254)
14046 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
14047 word-wrap under bidirectional display. (Bug#9224)
14049 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
14050 is non-zero, even if the data buffer is NULL. Fixes a crash in
14051 vertical-motion with longlines-mode. (Bug#9254)
14053 2011-08-05 Eli Zaretskii <eliz@gnu.org>
14055 * bidi.c <bidi_cache_total_alloc>: Now static.
14056 (bidi_initialize): Initialize bidi_cache_total_alloc.
14058 * xdisp.c (display_line): Release buffer allocated for shelved bidi
14061 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
14062 amount allocated this far in `bidi_cache_total_alloc'.
14063 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
14064 non-zero, only free the data buffer without restoring the cache
14065 contents. All callers changed.
14067 * dispextern.h (bidi_unshelve_cache): Update prototype.
14069 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
14070 (move_it_in_display_line, move_it_to)
14071 (move_it_vertically_backward, move_it_by_lines): Replace the call
14072 to xfree to an equivalent call to bidi_unshelve_cache.
14073 (move_it_in_display_line_to): Fix logic of returning
14074 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
14076 2011-08-05 Eli Zaretskii <eliz@gnu.org>
14078 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
14079 came from a string character with a `cursor' property. (Bug#9229)
14081 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
14083 * Makefile.in (LIB_PTHREAD): New variable.
14084 (LIBES): Add LIB_PTHREAD (Bug#9216).
14086 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
14087 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
14089 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
14091 * regex.c (re_iswctype): Remove some redundant boolean conversions.
14093 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
14095 * xterm.c (x_find_topmost_parent): New function.
14096 (x_set_frame_alpha): Find topmost parent window with
14097 x_find_topmost_parent and set the property there also (bug#9181).
14098 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
14100 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
14102 * callproc.c (Fcall_process): Avoid vfork clobbering
14103 the local vars buffer, coding_systems, current_dir.
14105 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>

14109 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
14111 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
14112 so that it is not optimized away.
14114 * xdisp.c (compute_display_string_pos): Remove unused local.
14116 2011-08-02 Eli Zaretskii <eliz@gnu.org>
14118 Fix slow cursor motion and scrolling in large buffers with
14119 selective display, like Org Mode buffers. (Bug#9218)
14121 * dispextern.h (struct bidi_it): New member disp_prop_p.
14123 * xdisp.c: Remove one-slot cache of display string positions.
14124 (compute_display_string_pos): Accept an additional argument
14125 DISP_PROP_P; callers changed. Scan at most 5K characters forward
14126 for a display string or property. If found, set DISP_PROP_P
14129 * bidi.c (bidi_fetch_char): Accept an additional argument
14130 DISP_PROP_P, and pass it to compute_display_string_pos.
14131 Only handle text covered by a display string if DISP_PROP_P is returned
14132 non-zero. All callers of bidi_fetch_char changed.
14134 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
14136 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
14138 2010-12-03 Don March <don@ohspite.net>
14140 * keymap.c (Fdefine_key): Fix non-prefix key error message when
14141 last character M-[char] is translated to ESC [char] (bug#7541).
14143 2011-08-02 Kenichi Handa <handa@m17n.org>
14145 * lisp.h (uniprop_table): Extern it.
14147 * chartab.c (uniprop_table): Make it non-static.
14149 2011-08-01 Eli Zaretskii <eliz@gnu.org>
14151 * xdisp.c (forward_to_next_line_start): Accept additional argument
14152 BIDI_IT_PREV, and store into it the state of the bidi iterator had
14154 (reseat_at_next_visible_line_start): Use the bidi iterator state
14155 returned by forward_to_next_line_start to restore the state of
14156 it->bidi_it after backing up to previous newline. (Bug#9212)
14158 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
14160 * regex.c (re_comp): Protoize.
14161 (re_exec): Fix return type.
14162 (regexec): Fix type of `ret'. (Bug#9203)
14164 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14166 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
14167 This is needed if max-image-size is a floating-point number.
14169 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
14171 * print.c (print_object): Print empty symbol as ##.
14173 * lread.c (read1): Read ## as empty symbol.
14175 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
14177 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
14178 setting frame foreground color (Bug#9175).
14179 (x_set_background_color): Likewise.
14181 * nsmenu.m (-setText): Size tooltip dimensions precisely to
14182 contents (Bug#9176).
14183 (EmacsTooltip -init): Remove bezels and add shadows to
14186 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
14187 or scroll bar (Bug#8470).
14189 * nsfont.m (nsfont_open): Remove assignment to voffset and
14190 unnecessary vars hshink, expand, hd, full_height, min_height.
14191 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
14193 * nsterm.h (nsfont_info): Remove voffset field.
14195 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
14197 Implement strike-through and overline on NextStep (Bug#8863).
14199 * nsfont.m (nsfont_open): Use underline position provided by font,
14200 instead of hard-coded value of 2.
14201 (nsfont_draw): Call ns_draw_text_decoration instead.
14203 * nsterm.h: Add declaration for ns_draw_text_decoration.
14205 * nsterm.m (ns_draw_text_decoration): New function for drawing
14206 underline, overline, and strike-through.

14208 ns_draw_text_decoration. Change treatment of cursor drawing to
14209 accommodate underlining, etc.
14211 2011-07-28 Eli Zaretskii <eliz@gnu.org>
14213 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
14216 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14218 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
14219 Without this fix, if a signal arrives just after memory fills up,
14220 'malloc' might be invoked reentrantly.
14222 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
14223 In other words, assume that every image size is allowed, on non-X
14224 hosts. This assumption is probably wrong, but it lets Emacs compile.
14226 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
14228 * regex.c (re_iswctype): Convert return values to boolean.
14230 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
14232 * xdisp.c (compute_display_string_pos): Don't use cached display
14233 string position if the buffer had its restriction changed.
14236 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14238 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
14240 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14242 Integer signedness and overflow and related fixes. (Bug#9079)
14244 * bidi.c: Integer size and overflow fixes.
14245 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
14246 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
14247 (bidi_cache_find_level_change, bidi_cache_ensure_space)
14248 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
14249 (bidi_find_other_level_edge):
14250 Use ptrdiff_t instead of EMACS_INT where either will do.
14251 This works better on 32-bit hosts configured --with-wide-int.
14252 (bidi_cache_ensure_space): Check for size-calculation overflow.
14253 Use % rather than repeated addition, for better worst-case speed.
14254 Don't set bidi_cache_size until after xrealloc returns, because it
14256 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
14257 (bidi_cache_ensure_space): Also check that the bidi cache size
14258 does not exceed that of the largest Lisp string or buffer. See Eli
14259 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
14261 * alloc.c (__malloc_size_t): Remove.
14262 All uses replaced by size_t. See Andreas Schwab's note
14263 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
14265 * image.c: Improve checking for integer overflow.
14266 (check_image_size): Assume that f is nonnull, since
14267 it is always nonnull in practice. This is one less thing to
14268 worry about when checking for integer overflow later.
14269 (x_check_image_size): New function, which checks for integer
14270 overflow issues inside X.
14271 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
14272 This removes the need for a memory_full check.
14273 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
14274 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
14275 (xbm_read_bitmap_data): Change locals back to 'int', since
14276 their values must fit in 'int'.
14277 (xpm_load_image, png_load, tiff_load):
14278 Invoke x_create_x_image_and_pixmap earlier,
14279 to avoid much needless work if the image is too large.
14280 (tiff_load): Treat overly large images as if
14281 x_create_x_image_and_pixmap failed, not as malloc failures.
14282 (gs_load): Use x_check_image_size.
14284 * gtkutil.c: Omit integer casts.
14285 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
14286 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
14288 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
14290 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
14291 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
14292 would wrongly return t on a 64-bit host.
14294 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
14295 The plain *_OVERFLOW macros run afoul of GCC bug 49705
14296 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
14297 and therefore cause GCC to emit a bogus diagnostic in some cases.
14299 * image.c: Integer signedness and overflow and related fixes.
14300 This is not an exhaustive set of fixes, but it's time to
14301 record what I've got.
14302 (lookup_pixel_color, check_image_size): Remove redundant decls.
14303 (check_image_size): Don't assume that arbitrary EMACS_INT values
14304 fit in 'int', or that arbitrary 'double' values fit in 'int'.
14305 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
14306 (tiff_load, imagemagick_load_image):
14307 Check for overflow in size calculations.
14308 (x_create_x_image_and_pixmap): Remove unnecessary test for
14309 xmalloc returning NULL; that can't happen.
14310 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
14311 (xpm_color_bucket): Use better integer hashing function.
14312 (xpm_cache_color): Don't possibly over-allocate memory.
14313 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
14314 (gif_memory_source):
14315 Use ptrdiff_t, not int or size_t, to record sizes.
14316 (png_load): Don't assume values greater than 2**31 fit in 'int'.
14317 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
14318 either works, as we prefer signed integers.
14319 (tiff_read_from_memory, tiff_write_from_memory):
14320 Return tsize_t, not size_t, since that's what the TIFF API wants.
14321 (tiff_read_from_memory): Don't fail simply because the read would
14322 go past EOF; instead, return a short read.
14323 (tiff_load): Omit no-longer-needed casts.
14324 (Fimagemagick_types): Don't assume size fits into 'int'.
14326 Improve hashing quality when configured --with-wide-int.
14327 * fns.c (hash_string): New function, taken from sxhash_string.
14328 Do not discard information about ASCII character case; this
14329 discarding is no longer needed.
14330 (sxhash-string): Use it. Change sig to match it. Caller changed.
14331 * lisp.h: Declare it.
14332 * lread.c (hash_string): Remove, since we now use fns.c's version.
14333 The fns.c version returns a wider integer if --with-wide-int is
14334 specified, so this should help the quality of the hashing a bit.
14336 * emacs.c: Integer overflow minor fix.
14337 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
14338 Define only if GNU_LINUX.
14339 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
14341 * dispnew.c: Integer signedness and overflow fixes.
14342 Remove unnecessary forward decls, that were a maintenance hassle.
14343 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
14345 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
14346 (scrolling_window): Use ptrdiff_t, not int, for byte count.
14347 (prepare_desired_row, line_draw_cost):
14348 Use int, not unsigned, where either works.
14349 (save_current_matrix, restore_current_matrix):
14350 Use ptrdiff_t, not size_t, where either works.
14351 (init_display): Check for overflow more accurately, and without
14352 relying on undefined behavior.
14354 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
14355 Remove, replacing with the new symbols in lisp.h. All uses changed.
14356 * fileio.c (make_temp_name):
14357 * filelock.c (lock_file_1, lock_file):
14358 * xdisp.c (message_dolog):
14359 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
14360 Use pMd etc. instead.
14361 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
14362 replacing the pWIDE etc. symbols removed from editfns.c.
14364 * keyboard.h (num_input_events): Now uintmax_t.
14365 This is (very slightly) less likely to mess up due to wraparound.
14368 * buffer.c: Integer signedness fixes.
14369 (alloc_buffer_text, enlarge_buffer_text):
14370 Use ptrdiff_t rather than size_t when either will do, as we prefer
14373 * alloc.c: Integer signedness and overflow fixes.
14374 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
14375 (__malloc_size_t): Default to size_t, not to int.
14376 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
14377 (Fgarbage_collect, mark_object_loop_halt, mark_object):
14378 Prefer ptrdiff_t to size_t when either would do, as we prefer
14380 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
14381 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
14382 Now const. Initialize with values that are in range even if char
14384 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
14385 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
14386 These functions do the right thing with sizes > 2**32.
14387 (check_depth): Now ptrdiff_t, not int.
14388 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
14389 Adjust to new way of storing sizes. Check for size overflow bugs
14391 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
14392 slightly wrong anyway, as it missed one instance of
14393 XMALLOC_OVERRUN_CHECK_OVERHEAD.
14394 (refill_memory_reserve): Omit needless cast to size_t.
14395 (mark_object_loop_halt): Mark as externally visible.
14397 * xselect.c: Integer signedness and overflow fixes.
14398 (Fx_register_dnd_atom, x_handle_dnd_message):
14399 Use ptrdiff_t, not size_t, since we prefer signed.
14400 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
14401 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
14402 x_dnd_atoms_size and x_dnd_atoms_length.
14404 * doprnt.c: Prefer signed to unsigned when either works.
14406 * doprnt.c (doprnt):
14408 * xdisp.c (vmessage):
14409 Use ptrdiff_t, not size_t, when using or implementing doprnt,
14410 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
14411 prefer signed arithmetic to avoid comparison confusion.
14412 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
14413 but is a bit tricky.
14415 Assume freestanding C89 headers, string.h, stdlib.h.
14416 * data.c, doprnt.c, floatfns.c, print.c:
14417 Include float.h unconditionally.
14418 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
14419 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
14420 * regex.c: Likewise for stddef.h, string.h.
14421 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
14422 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
14423 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
14424 (STDC_HEADERS): Remove obsolete defines.
14425 * sysdep.c: Include limits.h unconditionally.
14427 Assume support for memcmp, memcpy, memmove, memset.
14428 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
14429 * regex.c (memcmp, memcpy):
14430 Remove; we assume C89 now.
14432 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
14433 (__malloc_safe_bcopy): Remove; no longer needed.
14435 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
14436 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
14437 well either way, and we prefer signed to unsigned.
14439 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
14441 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
14442 closes the connection while we're reading (bug#9182).
14444 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
14446 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
14447 are specified (Bug#9168).
14449 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
14451 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
14452 Found by GCC static checking and --with-wide-int on a 32-bit host.
14454 2011-07-25 Eli Zaretskii <eliz@gnu.org>
14456 * xdisp.c (compute_display_string_pos): Fix logic of caching
14457 previous display string position. Initialize cached_prev_pos to
14458 -1. Fixes slow-down at the beginning of a buffer.
14460 2011-07-24 Eli Zaretskii <eliz@gnu.org>
14462 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
14463 for attrs[LFACE_FONTSET_INDEX].
14465 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
14467 * xml.c (parse_region): Remove unused local
14468 that was recently introduced.
14470 2011-07-23 Eli Zaretskii <eliz@gnu.org>
14472 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
14473 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
14475 * xdisp.c (move_it_in_display_line_to): Record the best matching
14476 position for TO_CHARPOS while scanning the line, and restore it on
14477 exit if none of the characters scanned was an exact match.
14478 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
14479 when exact match is impossible due to invisible text, and the
14480 lines are truncated.
14482 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
14484 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
14487 2011-07-22 Eli Zaretskii <eliz@gnu.org>
14489 Fix a significant slow-down of cursor motion with C-n, C-p,
14490 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
14491 auto-repeat under bidi redisplay in fontified buffers.
14492 * xdisp.c (compute_stop_pos_backwards): New function.
14493 (next_element_from_buffer): Call compute_stop_pos_backwards to
14494 find a suitable prev_stop when we find ourselves before
14496 (reseat): Don't look for prev_stop, as that could mean a very long
14498 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
14499 <cached_disp_overlay_modiff>: Cache for last found display string
14501 (compute_display_string_pos): Return the cached position if asked
14502 about the same buffer in the same area of character positions, and
14503 the buffer wasn't changed since the time the display string
14504 position was cached.
14506 2011-07-22 Eli Zaretskii <eliz@gnu.org>
14508 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
14509 is an integer, which is important for empty lines. (Bug#9149)
14511 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
14513 * frame.c (Fmodify_frame_parameters): In tty case, update the
14514 default face if necessary (Bug#4238).
14516 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
14518 * editfns.c (Fstring_to_char): No need to explain what a character
14519 is in the docstring (Bug#6576).
14521 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
14523 * xml.c (parse_region): Make sure we always return a tree.
14525 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
14527 * xml.c (parse_region): If a document contains only comments,
14530 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
14532 * xml.c (make_dom): Return comments, too.
14534 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
14537 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
14538 and the surrounding thread.
14539 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
14540 rather than fgets, and retry after EINTR. Otherwise, 'emacs
14541 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
14543 * s/openbsd.h (BROKEN_SIGIO): Define.
14544 * unexelf.c (unexec) [__OpenBSD__]:
14545 Don't update the .mdebug section of the Alpha COFF symbol table.
14547 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14549 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
14552 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
14554 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
14555 This fixes some race conditions on the permissions of any newly
14558 * alloc.c (valid_pointer_p): Use pipe, not open.
14559 This fixes some permissions issues when debugging.
14561 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
14562 If fchown fails to set both uid and gid, try to set just gid,
14563 as that is sometimes allowed. Adjust the file's mode to eliminate
14564 setuid or setgid bits that are inappropriate if fchown fails.
14566 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
14568 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
14569 to compare Lisp_Objects.
14570 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
14571 global_gnutls_log_level, don't mistake it for a Lisp_Object.
14572 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
14574 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
14576 * lread.c (read_integer): Unread even EOF character.
14577 (read1): Likewise. Properly record start position of symbol.
14579 * lread.c (read1): Read `#:' as empty uninterned symbol if no
14580 symbol character follows.
14582 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
14584 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
14585 This works around a problem with the previous change to Fcopy_file.
14586 Recent glibc declares fchown with __attribute__((warn_unused_result)),
14587 and without this change, GCC might complain about discarding
14588 fchown's return value.
14590 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
14592 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
14594 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
14596 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
14598 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
14600 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
14601 it's used from the C level.
14603 * process.c: Use the same condition for POLL_FOR_INPUT in both
14604 keyboard.c and process.c (bug#1858).
14606 2011-07-09 Lawrence Mitchell <wence@gmx.li>
14608 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
14609 (Fgnutls_boot): Use it.
14611 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
14613 * doc.c (Fsubstitute_command_keys): Revert last change.
14615 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
14617 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
14618 quotes the next character, and doesn't affect other longer
14619 sequences (bug#8935).
14621 * lread.c (syms_of_lread): Clarify that is isn't only
14622 `eval-buffer' and `eval-defun' that's affected by
14623 `lexical-binding' (bug#8460).
14625 2011-07-15 Eli Zaretskii <eliz@gnu.org>
14627 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
14628 bidi redisplay when a line includes both an image and is truncated.
14630 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
14632 Fix minor problems found by static checking.
14633 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
14634 (elsz): Now a signed constant, not a size_t var. We prefer signed
14635 types to unsigned, to avoid integer comparison confusion. Without
14636 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
14637 "cannot optimize loop, the loop counter may overflow", a symptom
14639 * indent.c (Fvertical_motion): Mark locals as initialized.
14640 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
14642 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
14644 * search.c (Fre_search_backward): Mention `case-fold-search' in
14645 all the re_search_* functions (bug#8138).
14647 * keyboard.c (Fopen_dribble_file): Document when the file is
14650 2011-07-14 Eli Zaretskii <eliz@gnu.org>
14652 * bidi.c (bidi_dump_cached_states): Fix format of displaying
14655 Support bidi reordering of display and overlay strings.

14657 (compute_display_string_end): Accept additional argument STRING.
14658 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
14659 (reseat_to_string): Initialize bidi_it->string.s and
14660 bidi_it->string.schars.
14661 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
14662 NULL (avoids a crash in bidi_paragraph_init).
14663 Initialize itb.string.lstring.
14664 (init_iterator): Call bidi_init_it only of a valid
14665 buffer position was specified. Initialize paragraph_embedding to
14667 (reseat_to_string): Initialize the bidi iterator.
14668 (display_string): If we need to ignore text properties of
14669 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
14670 original value of -1 will not work with bidi.)
14671 (compute_display_string_pos): First arg is now struct
14672 `text_pos *'; all callers changed. Support display properties on
14674 (compute_display_string_end): Support display properties on Lisp
14676 (init_iterator, reseat_1, reseat_to_string): Initialize the
14677 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
14678 when iterating on a string not from display properties).
14679 (compute_display_string_pos, compute_display_string_end):
14680 Fix calculation of the object to scan. Fixes an error when using
14682 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
14683 base_level_stop; instead, set base_level_stop to BEGV.
14684 Fixes crashes in vertical-motion.
14685 (next_element_from_buffer): Improve commentary for when
14686 the iterator is before prev_stop.
14687 (init_iterator): Initialize bidi_p from the default value of
14688 bidi-display-reordering, not from buffer-local value. Use the
14689 buffer-local value only if initializing for buffer iteration.
14690 (handle_invisible_prop): Support invisible properties on strings
14691 that are being bidi-reordered.
14692 (set_iterator_to_next): Support bidi reordering of C strings and
14694 (next_element_from_string): Support bidi reordering of Lisp
14696 (handle_stop_backwards): Support Lisp strings as well.
14697 (display_string): Support display of R2L glyph rows.
14698 Use IT_STRING_CHARPOS when displaying from a Lisp string.
14699 (init_iterator): Don't initialize it->bidi_p for strings
14701 (reseat_to_string): Initialize it->bidi_p for strings here.
14702 (next_element_from_string, next_element_from_c_string)
14703 (next_element_from_buffer): Add xassert's for correspondence
14704 between IT's object being iterated and it->bidi_it.string
14706 (face_before_or_after_it_pos): Support bidi iteration.
14707 (next_element_from_c_string): Handle the case of the first string
14708 character that is not the first one in the visual order.
14709 (get_visually_first_element): New function, refactored from common
14710 parts of next_element_from_buffer, next_element_from_string, and
14711 next_element_from_c_string.
14712 (tool_bar_lines_needed, redisplay_tool_bar)
14713 (display_menu_bar): Force left-to-right direction. Add a FIXME
14714 comment for making that be controlled by a user option.
14715 (push_it, pop_it): Save and restore the state of the
14716 bidi iterator. Save and restore the bidi_p flag.
14717 (pop_it): Iterate out of display property for string iteration as
14719 (iterate_out_of_display_property): Support iteration over strings.
14720 (handle_single_display_spec): Set up it->bidi_it for iteration
14721 over a display string, and call bidi_init_it.
14722 (handle_single_display_spec, next_overlay_string)
14723 (get_overlay_strings_1, push_display_prop): Set up the bidi
14724 iterator for displaying display or overlay strings.
14725 (forward_to_next_line_start): Don't use the shortcut if
14727 (back_to_previous_visible_line_start): If handle_display_prop
14728 pushed the iterator stack, restore the internal state of the bidi
14729 iterator by calling bidi_pop_it same number of times.
14730 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
14731 and we are bidi-iterating, don't decrement the iterator position;
14732 instead, set the first_elt flag in the bidi iterator, to produce
14734 (reseat_1): Remove redundant setting of string_from_display_prop_p.
14735 (push_display_prop): xassert that we are iterating a buffer.
14736 (push_it, pop_it): Save and restore paragraph_embedding member.
14737 (handle_single_display_spec, next_overlay_string)
14738 (get_overlay_strings_1, reseat_1, reseat_to_string)
14739 (push_display_prop): Set up the `unibyte' member of bidi_it.string
14740 correctly. Don't assume unibyte strings are not bidi-reordered.
14741 (compute_display_string_pos)
14742 (compute_display_string_end): Fix handling the case of C string.
14743 (push_it, pop_it): Save and restore from_disp_prop_p.

15203 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
15205 Random fixes. E.g., (random) never returned negative values.
15206 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
15207 subseconds part to the entropy, as that's a bit more random.
15208 Prefer signed to unsigned, since the signedness doesn't matter and
15209 in general we prefer signed. When given a limit, use a
15210 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
15211 latter isn't right if USE_2_TAGS_FOR_INTS.
15212 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
15213 not 0..VALMASK. Don't discard "excess" bits that random () returns.
15215 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
15217 * textprop.c (text_property_stickiness):
15218 Obey Vtext_property_default_nonsticky.

15225 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
15226 This is more efficient than Ffile_directory_p and avoids a minor race.
15228 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
15230 * buffer.c (Foverlay_put): Say what the return value is
15233 * fileio.c (barf_or_query_if_file_exists): Check first if the file
15234 is a directory before asking whether to use the file name
15236 (barf_or_query_if_file_exists): Make the "File is a directory"
15237 error be more correct.
15239 * fns.c (Frequire): Remove the mention of the .gz files, since
15240 that's installation-specific, but keep the mention of
15241 `get-load-suffixes'.
15243 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
15245 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

15250 * gnutls.c (Fgnutls_boot): Don't mention :verify-error.
15251 (syms_of_gnutls): Remove duplicate DEFSYM for
15252 Qgnutls_bootprop_verify_hostname_error, an error for
15253 Qgnutls_bootprop_verify_error (which is no longer used).
15255 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
15256 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
15257 Also (re)move comments that are misplaced or no longer relevant.
15259 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15261 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

15265 * xfaces.c (Finternal_merge_in_global_face): Modify the foreground
15266 and background color parameters if they have been changed.

15286 * lread.c (syms_of_lread): Mention single symbols defined by
15287 `defvar' or `defconst' (bug#7154).
15289 * fns.c (Frequire): Mention .el.gz files (bug#7314).
15290 (Frequire): Mention get-load-suffixes.
15292 2011-07-02 Martin Rudalics <rudalics@gmx.at>

15320 (syms_of_keymap): Defsubr make-composed-keymap.
15321 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

15358 * eval.c (struct backtrace): Simplify and port the data structure.
15359 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
15360 signed bit field, as this assumption is not portable and it makes
15361 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
15362 "char debug_on_exit : 1" as this is not portable either; instead,
15363 use the portable "unsigned int debug_on_exit : 1". Remove unused
15364 member evalargs. Remove obsolete comments about cc bombing out.
15366 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>
15368 * xsettings.c: Include glib-object.h, gio/gio.h if HAVE_GSETTINGS.

15434 (emacs_fixed_new): Set priv->f to argument.
15435 (emacs_fixed_get_preferred_width)
15436 (emacs_fixed_get_preferred_height): Use min_width/height from
15437 frames size_hint to set minimum and natural (Bug#8919).
15438 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
15439 and use min_width/height from frames size_hint to set
15440 min_width/height (Bug#8919).

15532 * print.c (printchar, strout): Check for string overflow.
15533 (PRINTPREPARE, printchar, strout):
15534 Don't set size unless allocation succeeds.
15536 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
15537 for sizes. Check for string overflow more accurately.

15541 * keyboard.h (struct keyboard.kbd_macro_bufsize):
15542 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

15551 (read_integer): Radix is now EMACS_INT, not int,
15552 to improve quality of diagnostics for out-of-range radices.
15553 Calculate buffer size correctly for out-of-range radices.
15554 (read1): Check for integer overflow in radices, and in
15555 read-circle numbers.
15556 (read_escape): Avoid int overflow.
15557 (Fload, openp, read_buffer_size, read1)
15558 (substitute_object_recurse, read_vector, read_list, map_obarray):
15559 Use ptrdiff_t, not int, for sizes.

15579 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
15581 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
15582 The following patches are for when GLYPH_DEBUG && !XASSERT.
15583 * dispextern.h (trace_redisplay_p, dump_glyph_string):
15584 * dispnew.c (flush_stdout):
15585 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
15586 Mark as externally visible.
15587 * dispnew.c (check_window_matrix_pointers): Now static.
15588 * dispnew.c (window_to_frame_vpos):
15589 * xfns.c (unwind_create_frame):
15590 * xterm.c (x_check_font): Remove unused local.

15596 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
15598 (debug_method_add): Use va_list and vsprintf rather than relying
15599 on undefined behavior with wrong number of arguments.
15600 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
15601 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
15602 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
15603 since we're not interested in debugging glyphs with old libraries.
15604 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
15605 GCC 4.6.0's static checking.
15607 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

15623 * xfaces.c (load_pixmap):
15624 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
15625 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
15626 (.bitmaps_last, struct x_output.icon_bitmap):
15627 Use ptrdiff_t, not int, for bitmap indexes.
15628 (x_allocate_bitmap_record): Check for size overflow.
15629 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
15631 Use ptrdiff_t, not int, for overlay counts.
15632 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
15633 * editfns.c (overlays_around, get_pos_property):
15634 * textprop.c (get_char_property_and_overlay):
15635 * xdisp.c (next_overlay_change, note_mouse_highlight):
15636 * xfaces.c (face_at_buffer_position):
15637 * buffer.c (OVERLAY_COUNT_MAX): New macro.
15638 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
15639 (Fnext_overlay_change, Fprevious_overlay_change)
15640 (mouse_face_overlay_overlaps, Foverlays_in):
15641 Use ptrdiff_t, not int, for sizes.
15642 (overlays_at, overlays_in): Check for size-calculation overflow.
15644 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
15646 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
15647 (x_session_initialize): Do not assume string length fits in int.
15649 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
15650 This is unlikely, but can occur if DPI is outlandish.
15652 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
15653 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
15655 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
15656 * xrdb.c (magic_file_p, search_magic_path):
15657 Omit last arg SUFFIX; it was always 0. All callers changed.
15658 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
15660 * xfont.c (xfont_match): Avoid need for strlen.
15662 * xfns.c: Don't assume strlen fits in int.
15663 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
15665 * xdisp.c (message_log_check_duplicate): Return intmax_t,
15666 not unsigned long, as we prefer signed integers. All callers changed.
15667 Detect integer overflow in repeat count.
15668 (message_dolog): Don't assume print length fits in 39 bytes.
15669 (display_mode_element): Don't assume strlen fits in int.
15671 * termcap.c: Don't assume sizes fit in int and never overflow.
15672 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
15673 (gobble_line): Check for size-calculation overflow.
15675 * minibuf.c (Fread_buffer):
15676 * lread.c (intern, intern_c_string):
15677 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
15678 Don't assume string length fits in int.
15680 * keyboard.c (parse_tool_bar_item):
15681 * gtkutil.c (style_changed_cb): Avoid need for strlen.
15683 * font.c: Don't assume string length fits in int.
15684 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
15685 Use ptrdiff_t, not int.
15686 (font_intern_prop): Don't assume string length fits in int.
15687 Don't assume integer property fits in fixnum.
15688 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
15690 * filelock.c: Fix some buffer overrun and integer overflow issues.
15691 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
15692 Reformulate so as not to need the command string.
15693 Invoke gzip -cd rather than gunzip, as it's more portable.
15694 (lock_info_type, lock_file_1, lock_file):
15695 Don't assume pid_t and time_t fit in unsigned long.
15696 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
15697 (current_lock_owner): Prefer signed type for sizes.
15698 Use memcpy, not strncpy, where memcpy is what is really wanted.
15699 Don't assume (via atoi) that time_t and pid_t fit in int.
15700 Check for time_t and/or pid_t out of range, e.g., via a network share.
15701 Don't alloca where an auto var works fine.
15703 * fileio.c: Fix some integer overflow issues.
15704 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
15705 Don't assume string length fits in int.
15706 (directory_file_name): Don't assume string length fits in long.
15707 (make_temp_name): Don't assume pid fits in int, or that its print
15708 length is less than 20.
15710 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
15712 * coding.c (make_subsidiaries): Don't assume string length fits in int.
15714 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
15716 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
15717 We prefer signed integers, even for size calculations.
15719 * emacs.c: Don't assume string length fits in 'int'.
15720 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
15721 (main): Don't invoke strlen when not needed.
15723 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
15724 (XD_DEBUG_MESSAGE): Don't waste a byte.
15726 * callproc.c (getenv_internal_1, getenv_internal)
15727 (Fgetenv_internal):
15728 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
15730 * lread.c (invalid_syntax): Omit length argument.
15731 All uses changed. This doesn't fix a bug, but it simplifies the
15732 code away from its former Hollerith-constant appearance, and it's
15733 one less 'int' to worry about when looking at integer-overflow issues.
15734 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
15736 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
15737 This didn't break anything, but it didn't help either.
15738 It's confusing to put a bogus integer in a place where the actual
15739 value does not matter.
15740 (LIST_END_P): Remove unused macro and its bogus comment.
15741 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
15743 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
15744 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
15746 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
15747 We prefer signed types, and the value cannot exceed the EMACS_INT
15748 range anyway (because otherwise the length would not be representable).
15749 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
15750 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
15751 This avoids a GCC warning when WIDE_EMACS_INT.
15753 * indent.c (sane_tab_width): New function.
15754 (current_column, scan_for_column, Findent_to, position_indentation)
15755 (compute_motion): Use it. This is just for clarity.
15756 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
15758 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
15760 * lisp.h (lint_assume): New macro.
15761 * composite.c (composition_gstring_put_cache):
15762 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
15764 * editfns.c, insdel.c:
15765 Omit unnecessary forward decls, to simplify future changes.
15767 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
15769 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
15771 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
15772 Use much-faster test for byte-length change.
15773 Don't assume string byte-length fits in 'int'.
15774 Check that character arg fits in 'int'.
15775 (mapcar1): Declare byte as byte, for clarity.
15777 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
15779 * fns.c (concat): Catch string overflow earlier.
15780 Do not rely on integer wraparound.
15782 * dispextern.h (struct it.overlay_strings_charpos)
15783 (struct it.selective): Now EMACS_INT, not int.
15784 * xdisp.c (forward_to_next_line_start)
15785 (back_to_previous_visible_line_start)
15786 (reseat_at_next_visible_line_start, next_element_from_buffer):
15787 Don't arbitrarily truncate the value of 'selective' to int.
15789 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
15791 * composite.c: Don't truncate sizes to 'int'.
15792 (composition_gstring_p, composition_reseat_it)
15793 (composition_adjust_point): Use EMACS_INT, not int.
15794 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
15795 not EMACS_UINT, for indexes.
15797 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
15799 * buffer.c: Include <verify.h>.
15800 (struct sortvec.priority, struct sortstr.priority):
15801 Now EMACS_INT, not int.
15802 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
15803 (struct sortstr.size, record_overlay_string)
15804 (struct sortstrlist.size, struct sortlist.used):
15805 Don't truncate size to int.
15806 (record_overlay_string): Check for size-calculation overflow.
15807 (init_buffer_once): Check at compile-time, not run-time.
15809 2011-06-22 Jim Meyering <meyering@redhat.com>
15811 Don't leak an XBM-image-sized buffer
15812 * image.c (xbm_load): Free the image buffer after using it.
15814 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
15817 * composite.c (find_automatic_composition): Omit needless 'return 0;'
15818 that Sun C diagnosed.
15819 * fns.c (secure_hash): Fix pointer signedness issue.
15820 * intervals.c (static_offset_intervals): New function.
15821 (offset_intervals): Use it.
15823 2011-06-21 Leo Liu <sdl.web@gmail.com>
15826 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
15829 * fns.c (secure_hash): Rename from crypto_hash_function and change
15830 the first arg to accept symbols.
15831 (Fsecure_hash): New primitive.
15832 (syms_of_fns): New symbols.
15834 2011-06-20 Deniz Dogan <deniz@dogan.se>
15836 * process.c (Fset_process_buffer): Clarify return value in
15839 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
15841 * dispnew.c (add_window_display_history): Use BVAR.
15843 * xdisp.c (debug_method_add): Use BVAR.
15844 (check_window_end, dump_glyph_matrix, dump_glyph)
15845 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
15847 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
15850 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
15851 check till after the cache is created in init_frame_faces.
15853 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
15855 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
15857 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
15859 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
15860 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
15861 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
15863 Improve buffer-overflow checking (Bug#8873).
15864 * fileio.c (Finsert_file_contents):
15865 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
15866 Remove the old (too-loose) buffer overflow checks.
15867 They weren't needed, since make_gap checks for buffer overflow.
15868 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
15869 The old code merely checked for Emacs fixnum overflow, and relied
15870 on undefined (wraparound) behavior. The new code avoids undefined
15871 behavior, and also checks for ptrdiff_t and/or size_t overflow.
15873 * editfns.c (Finsert_char): Don't dump core with very negative counts.
15874 Tune. Don't use wider integers than needed. Don't use alloca.
15875 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
15877 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
15879 * insdel.c, lisp.h (buffer_overflow): New function.
15880 (insert_from_buffer_1, replace_range, replace_range_2):
15881 * insdel.c (make_gap_larger):
15882 * editfns.c (Finsert_char):
15883 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
15885 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
15887 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
15889 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
15891 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
15892 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
15894 * fileio.c: Don't assume EMACS_INT fits in off_t.
15895 (emacs_lseek): New static function.
15896 (Finsert_file_contents, Fwrite_region): Use it.
15897 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
15899 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
15901 * fns.c: Don't overflow int when computing a list length.
15902 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
15903 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
15904 truncation on 64-bit hosts. Check for QUIT every
15905 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
15906 faster and is responsive enough.
15907 (Flength): Report an error instead of overflowing an integer.
15908 (Fsafe_length): Return a float if the value is not representable
15909 as a fixnum. This shouldn't happen except in contrived situations.
15910 (Fnthcdr, Fsort): Don't assume list length fits in int.
15911 (Fcopy_sequence): Don't assume vector length fits in int.
15913 * alloc.c: Check that resized vectors' lengths fit in fixnums.
15914 (header_size, word_size): New constants.
15915 (allocate_vectorlike): Don't check size overflow here.
15916 (allocate_vector): Check it here instead, since this is the only
15917 caller of allocate_vectorlike that could cause overflow.
15918 Check that the new vector's length is representable as a fixnum.
15920 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
15921 The previous code was bogus. For example, next_almost_prime (32)
15922 returned 39, which is undesirable as it is a multiple of 3; and
15923 next_almost_prime (24) returned 25, which is a multiple of 5 so
15924 why was the code bothering to check for multiples of 7?
15926 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
15928 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
15930 Variadic C functions now count arguments with ptrdiff_t.
15931 This partly undoes my 2011-03-30 change, which replaced int with size_t.
15932 Back then I didn't know that the Emacs coding style prefers signed int.
15933 Also, in the meantime I found a few more instances where arguments
15934 were being counted with int, which may truncate counts on 64-bit
15935 machines, or EMACS_INT, which may be unnecessarily wide.
15936 * lisp.h (struct Lisp_Subr.function.aMANY)
15937 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
15938 Arg counts are now ptrdiff_t, not size_t.
15939 All variadic functions and their callers changed accordingly.
15940 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
15941 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
15942 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
15943 * callint.c (Fcall_interactively): Check arg count for overflow,
15944 to avoid potential buffer overrun. Use signed char, not 'int',
15945 for 'varies' array, so that we needn't bother to check its size
15946 calculation for overflow.
15947 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
15948 * eval.c (apply_lambda):
15949 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
15950 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
15951 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
15953 * callint.c (Fcall_interactively): Don't use index var as event count.
15955 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
15956 * mem-limits.h (SIZE): Remove; no longer used.
15958 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
15960 Remove unnecessary casts.
15961 * xterm.c (x_term_init):
15962 * xfns.c (x_set_border_pixel):
15963 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
15964 These aren't needed now that we assume ANSI C.
15966 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
15967 It's more likely to cause problems (due to unsigned overflow)
15970 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
15972 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
15974 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
15976 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
15978 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
15980 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
15982 GLYPH_CODE_FACE returns EMACS_INT, not int.
15983 * dispextern.h (merge_faces):
15984 * xfaces.c (merge_faces):
15985 * xdisp.c (get_next_display_element, next_element_from_display_vector):
15986 Don't assume EMACS_INT fits in int.
15988 * character.h (CHAR_VALID_P): Remove unused parameter.
15989 * fontset.c, lisp.h, xdisp.c: All uses changed.
15991 * editfns.c (Ftranslate_region_internal): Omit redundant test.
15993 * fns.c (concat): Minor tuning based on overflow analysis.
15994 This doesn't fix any bugs. Use int to hold character, instead
15995 of constantly refetching from Emacs object. Use XFASTINT, not
15996 XINT, for value known to be a character. Don't bother comparing
15997 a single byte to 0400, as it's always less.
15999 * floatfns.c (Fexpt):
16000 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
16002 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
16005 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
16007 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
16008 Without this fix, on a 64-bit host (aset S 0 4294967386) would
16009 incorrectly succeed when S was a string, because 4294967386 was
16010 truncated before it was used.
16012 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
16013 Otherwise, an out-of-range integer could cause undefined behavior
16016 * composite.c: Use int, not EMACS_INT, for characters.
16017 (fill_gstring_body, composition_compute_stop_pos): Use int, not
16018 EMACS_INT, for values that are known to be in character range.
16019 This doesn't fix any bugs but is the usual style inside Emacs and
16020 may generate better code on 32-bit machines.
16022 Make sure a 64-bit char is never passed to ENCODE_CHAR.
16023 This is for reasons similar to the recent CHAR_STRING fix.
16024 * charset.c (Fencode_char): Check that character arg is actually
16025 a character. Pass an int to ENCODE_CHAR.
16026 * charset.h (ENCODE_CHAR): Verify that the character argument is no
16027 wider than 'int', as a compile-time check to prevent future regressions
16030 * character.c (char_string): Remove unnecessary casts.
16032 Make sure a 64-bit char is never passed to CHAR_STRING.
16033 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
16034 by silently ignoring the top 32 bits, allowing some values
16035 that were far too large to be valid characters.
16036 * character.h: Include <verify.h>.
16037 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
16038 arguments are no wider than unsigned, as a compile-time check
16039 to prevent future regressions in this area.
16041 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
16042 (Fsubst_char_in_region):
16044 * xdisp.c (decode_mode_spec_coding):
16045 Adjust to CHAR_STRING's new requirement.
16046 * editfns.c (Finsert_char, Fsubst_char_in_region):
16047 * fns.c (concat): Check that character args are actually
16048 characters. Without this test, these functions did the wrong
16049 thing with wildly out-of-range values on 64-bit hosts.
16051 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
16052 These casts should not be needed on 32-bit hosts, either.
16053 * keyboard.c (read_char):
16054 * lread.c (Fload): Remove casts to unsigned.
16056 * lisp.h (UNSIGNED_CMP): New macro.
16057 This fixes comparison bugs on 64-bit hosts.
16058 (ASCII_CHAR_P): Use it.
16059 * casefiddle.c (casify_object):
16060 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
16061 (SINGLE_BYTE_CHAR_P, CHAR_STRING):

16064 * keyboard.c (read_char): Use UNSIGNED_CMP.
16066 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,

16104 These were 'int' variables that could overflow on 64-bit hosts;
16105 they were never used, so remove them instead of repairing them.

16114 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
16115 when a (possibly-narrower) signed value would do just as well.
16116 We prefer using signed arithmetic, to avoid comparison confusion.
16118 * alloc.c: Catch some string size overflows that we were missing.
16119 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
16120 for convenience in STRING_BYTES_MAX.
16121 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
16122 The definition here is exact; the one in lisp.h was approximate.
16123 (allocate_string_data): Check for string overflow. This catches
16124 some instances we weren't catching before. Also, it catches
16125 size_t overflow on (unusual) hosts where SIZE_MAX <= min
16126 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
16127 and ptrdiff_t and EMACS_INT are both 64 bits.
16129 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
16130 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.

16708 instead of using explicit *_CHAR codes.
16709 (bidi_resolve_explicit, bidi_resolve_weak):

16718 (bidi_level_of_next_char): Don't try to lookup the cache for the
16719 next/previous character if nothing is cached there yet, or if we
16720 were just reseat()'ed to a new position.
16722 * xdisp.c (set_cursor_from_row): Set start and stop points
16723 according to the row's direction when priming the loop that looks
16724 for the glyph on which to display cursor.

16726 (display_prop_intangible_p): Reimplement to call
16727 handle_display_spec instead of single_display_spec_intangible_p.
16728 Accept 3 additional arguments needed by handle_display_spec.
16729 This fixes incorrect cursor motion across display property with complex
16730 values: lists, `(when COND...)' forms, etc.

16738 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
16739 value of a `display' property is a "replacing spec".
16740 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
16741 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
16742 the display property, but just return a value indicating whether
16743 the display property will replace the characters it covers.
16744 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
16745 frame_window_p members of struct bidi_it.
16746 (compute_display_string_pos, compute_display_string_end):

16769 All callers changed. (Bug#8762)
16771 * gnutls.c: Use Emacs's memory allocators.
16772 Without this change, the gnutls library would invoke malloc etc.
16773 directly, which causes problems on non-SYNC_INPUT hosts, and which
16774 runs afoul of improving memory_full behavior. (Bug#8761)
16775 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
16776 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
16777 xfree instead of the default malloc, realloc, free.
16778 (Fgnutls_boot): No need to check for memory allocation failure,
16779 since xmalloc does that for us.

16801 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
16802 for hashes and hash indexes, instead of 'unsigned' and 'int'.
16803 * alloc.c (allocate_vectorlike):
16804 Check for overflow in vector size calculations.
16805 * ccl.c (ccl_driver):
16806 Check for overflow when converting EMACS_INT to int.

16808 need to be updated by these changes.
16809 * fns.c (make_hash_table, maybe_resize_hash_table):
16810 Check for integer overflow with large hash tables.
16811 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
16812 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
16813 (SXHASH_REDUCE): New macro.
16814 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
16815 Use it instead of discarding useful hash info with large hash values.
16816 (sxhash_float): New function.
16817 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
16818 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
16819 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
16820 Rewrite to use FIXNUM_BITS, as this simplifies things.
16821 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
16822 Adjust signatures to match updated version of code.
16823 (consing_since_gc): Now EMACS_INT, since a single hash table can
16824 use more than INT_MAX bytes.

16873 Make it possible to run ./temacs.
16875 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
16876 syms_of_callproc does the same thing. Remove test for

16934 2011-05-28 Jim Meyering <meyering@redhat.com>
16936 Avoid a sign-extension bug in crypto_hash_function.
16937 * fns.c (to_uchar): Define.
16938 (crypto_hash_function): Use it to convert some newly-signed
16939 variables to unsigned, to avoid sign-extension bugs. For example,
16940 without this change, (md5 "truc") would evaluate to
16941 45723a2aff78ff4fff7fff1114760e62 rather than the expected
16942 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
16943 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
16945 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
16947 Integer overflow fixes.
16949 * dbusbind.c: Serial number integer overflow fixes.
16950 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
16951 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
16952 to hold a serial number that is too large for a fixnum.
16953 (Fdbus_method_return_internal, Fdbus_method_error_internal):
16954 Check for serial numbers out of range. Decode any serial number
16955 that was so large that it became a float. (Bug#8722)
16957 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
16958 (Fdbus_call_method, Fdbus_call_method_asynchronously):
16959 Use XFASTINT rather than XUINT when numbers are nonnegative.
16960 (xd_append_arg, Fdbus_method_return_internal):
16961 (Fdbus_method_error_internal): Likewise. Also, for unsigned
16962 arguments, check that Lisp number is nonnegative, rather than
16963 silently wrapping negative numbers around. (Bug#8722)
16964 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
16967 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
16969 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
16971 ccl: Add integer overflow checks.
16972 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
16973 (IN_INT_RANGE): New macros.
16974 (ccl_driver): Use them to check for integer overflow when
16975 decoding a CCL program. Many of the new checks are whether XINT (x)
16976 fits in int; it doesn't always, on 64-bit hosts. The new version
16977 doesn't catch all possible integer overflows, but it's an
16978 improvement. (Bug#8719)
16980 * alloc.c (make_event_array): Use XINT, not XUINT.
16981 There's no need for unsigned here.
16983 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
16984 This follows up to the 2011-05-06 change that substituted uintptr_t
16985 for EMACS_INT. This case wasn't caught back then.
16987 Rework Fformat to avoid integer overflow issues.
16988 * editfns.c: Include <float.h> unconditionally, as it's everywhere
16989 now (part of C89). Include <verify.h>.
16990 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
16991 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
16992 (Fformat): Avoid the prepass trying to compute sizes; it was only
16993 approximate and thus did not catch overflow reliably. Instead, walk
16994 through the format just once, formatting and computing sizes as we go,
16995 checking for integer overflow at every step, and allocating a larger
16996 buffer as needed. Keep track separately whether the format is
16997 multibyte. Keep only the most-recently calculated precision, rather
16998 than them all. Record whether each argument has been converted to
16999 string. Use EMACS_INT, not int, for byte and char and arg counts.
17000 Support field widths and precisions larger than INT_MAX. Avoid
17001 sprintf's undefined behavior with conversion specifications such as %#d
17002 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
17003 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
17004 formatting out-of-range floating point numbers with int
17005 formats. (Bug#8668)
17007 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
17009 * data.c: Avoid integer truncation in expressions involving floats.
17010 * data.c: Include <intprops.h>.
17011 (arith_driver): When there's an integer overflow in an expression
17012 involving floating point, convert the integers to floating point
17013 so that the resulting value does not suffer from catastrophic
17014 integer truncation. For example, on a 64-bit host (* 4
17015 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
17016 Do not rely on undefined behavior after integer overflow.
17018 merge count_size_as_multibyte, parse_str_to_multibyte
17019 * character.c, character.h (count_size_as_multibyte):
17020 Rename from parse_str_to_multibyte; all uses changed.
17021 Check for integer overflow.
17022 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
17023 since it's now a duplicate of the other. This is more of
17024 a character than a buffer op, so better that it's in character.c.
17025 * fns.c, print.c: Adjust to above changes.
17027 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
17029 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
17031 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17033 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17034 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
17035 (x_clipboard_manager_save): Now static.
17036 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
17038 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17039 (crypto_hash_function): Now static.
17040 Fix pointer signedness problems. Avoid unnecessary initializations.
17042 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
17044 * termhooks.h (Vselection_alist): Make it terminal-local.
17046 * terminal.c (create_terminal): Initialize it.
17048 * xselect.c: Support for clipboard managers.
17049 (Vselection_alist): Move to termhooks.h as terminal-local var.
17050 (LOCAL_SELECTION): New macro.
17051 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
17052 (symbol_to_x_atom): Remove gratuitous arg.
17053 (x_handle_selection_request, lisp_data_to_selection_data)
17054 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
17055 (x_own_selection, x_get_local_selection, x_convert_selection):
17056 New arg, specifying work frame. Use terminal-local Vselection_alist.
17057 (some_frame_on_display): Delete unused function.
17058 (Fx_own_selection_internal, Fx_get_selection_internal)
17059 (Fx_disown_selection_internal, Fx_selection_owner_p)
17060 (Fx_selection_exists_p): New optional frame arg.
17061 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
17062 (x_handle_selection_clear): Don't treat other terminals with the
17063 same keyboard specially. Use the terminal-local Vselection_alist.
17064 (x_clear_frame_selections): Use Frun_hook_with_args.
17066 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
17068 * xterm.h: Add support for those atoms.
17070 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
17072 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
17073 (converted_selections, conversion_fail_tag): New global variables.
17074 (x_selection_request_lisp_error): Free the above.
17075 (x_get_local_selection): Remove unnecessary code.
17076 (x_reply_selection_request): Args changed; handle arbitrary array
17077 of converted selections stored in converted_selections.
17078 Separate the XChangeProperty and SelectionNotify steps.
17079 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
17080 (x_convert_selection): New function.
17081 (x_handle_selection_event): Simplify.
17082 (x_get_foreign_selection): Don't ignore incoming requests while
17083 waiting for an answer; this will fail when we implement
17084 SAVE_TARGETS, and seems unnecessary anyway.
17085 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
17086 (Vx_sent_selection_functions): Doc fix.
17088 2011-05-26 Leo Liu <sdl.web@gmail.com>
17090 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
17092 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17094 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
17096 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
17097 for fringe update if it has periodic bitmap.
17098 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
17099 and fringe_bitmap_periodic_p.
17101 * fringe.c (get_fringe_bitmap_data): New function.
17102 (draw_fringe_bitmap_1, update_window_fringes): Use it.
17103 (update_window_fringes): Record periodicity of fringe bitmap in glyph
17104 row. Mark glyph row for fringe update if periodicity changed.
17106 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
17107 for fringe update unless it has periodic bitmap.
17109 2011-05-25 Kenichi Handa <handa@m17n.org>
17111 * xdisp.c (get_next_display_element): Set correct it->face_id for
17112 a static composition.
17114 2011-05-24 Leo Liu <sdl.web@gmail.com>
17117 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
17119 * fns.c (crypto_hash_function, Fsha1): New function.
17120 (Fmd5): Use crypto_hash_function.
17121 (syms_of_fns): Add Ssha1.
17123 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
17125 * gnutls.c: Remove unused macros.
17126 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
17127 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
17128 Remove macros that are defined and never used.
17129 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
17131 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17133 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
17134 (Fx_get_selection_internal): Minor cleanup.
17135 (Fx_own_selection_internal): Rename arguments for consistency with
17138 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
17140 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
17142 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17144 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
17146 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17148 * dispnew.c (scrolling_window): Don't exclude the case that the
17149 last enabled row in the desired matrix touches the bottom boundary.
17151 2011-05-21 Glenn Morris <rgm@gnu.org>
17153 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
17154 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
17155 and add some more files.
17157 2011-05-20 Eli Zaretskii <eliz@gnu.org>
17159 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
17160 report_file_error introduced by the change from 2011-05-07.
17162 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
17164 * systime.h (Time): Define only if emacs is defined.
17165 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
17166 where the include path doesn't have X11/X.h by default. See
17167 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
17169 2011-05-20 Kenichi Handa <handa@m17n.org>
17171 * composite.c (find_automatic_composition): Fix previous change.
17173 2011-05-20 Glenn Morris <rgm@gnu.org>
17175 * lisp.mk: New file, split from Makefile.in.
17176 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
17177 (shortlisp): Remove.
17178 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
17180 2011-05-19 Glenn Morris <rgm@gnu.org>
17182 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
17183 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
17184 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
17185 (lisp): Set the order to that of loadup.el.
17186 (shortlisp): Make it a copy of $lisp.
17187 (SOME_MACHINE_LISP): Remove.
17188 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
17189 Use just $shortlisp, not $SOME_MACHINE_LISP too.
17191 2011-05-18 Kenichi Handa <handa@m17n.org>
17193 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
17194 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
17195 (find_automatic_composition): Mostly rewrite for efficiency.
17197 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
17199 * makefile.w32-in: Update dependencies.
17201 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
17203 * menu.c: Include limits.h (fixes the MS-Windows build broken by
17204 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
17206 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
17208 Fix some integer overflow issues, such as string length overflow.
17210 * insdel.c (count_size_as_multibyte): Check for string overflow.
17212 * character.c (lisp_string_width): Check for string overflow.
17213 Use EMACS_INT, not int, for string indexes and lengths; in
17214 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
17215 the resulting string length overflows an EMACS_INT; instead,
17216 report a string overflow if no precision given. When checking for
17217 precision exhaustion, use a check that cannot possibly have
17218 integer overflow. (Bug#8675)
17219 * character.h (lisp_string_width): Adjust to new signature.
17221 * alloc.c (string_overflow): New function.
17222 (Fmake_string): Use it. This doesn't change behavior, but saves
17223 a few bytes and will simplify future changes.
17224 * character.c (string_escape_byte8): Likewise.
17225 * lisp.h (string_overflow): New decl.
17227 Fixups, following up to the user-interface timestamp change.
17228 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
17229 for UI timestamps, instead of unsigned long.
17230 * msdos.c (mouse_get_pos): Likewise.
17231 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
17232 * w32gui.h (Time): Define by including "systime.h" rather than by
17233 declaring it ourselves. (Bug#8664)
17235 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
17236 * image.c (clear_image_cache): Likewise.
17238 * term.c (term_mouse_position): Don't assume time_t wraparound.
17240 Be more systematic about user-interface timestamps.
17241 Before, the code sometimes used 'Time', sometimes 'unsigned long',
17242 and sometimes 'EMACS_UINT', to represent these timestamps.
17243 This change causes it to use 'Time' uniformly, as that's what X uses.
17244 This makes the code easier to follow, and makes it easier to catch
17245 integer overflow bugs such as Bug#8664.
17246 * frame.c (Fmouse_position, Fmouse_pixel_position):
17247 Use Time, not unsigned long, for user-interface timestamps.
17248 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
17249 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
17250 * keyboard.h (last_event_timestamp): Likewise.
17251 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
17252 * menu.h (xmenu_show): Likewise.
17253 * term.c (term_mouse_position): Likewise.
17254 * termhooks.h (struct input_event.timestamp): Likewise.
17255 (struct terminal.mouse_position_hook): Likewise.
17256 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
17257 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
17258 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
17259 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
17260 what it was before.
17261 * menu.h, termhooks.h: Include "systime.h", for Time.
17263 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
17264 Don't assume that the difference between two unsigned long values
17265 can fit into an integer. At this point, we know button_down_time
17266 <= event->timestamp, so the difference must be nonnegative, so
17267 there's no need to cast the result if double-click-time is
17268 nonnegative, as it should be; check that it's nonnegative, just in
17269 case. This bug is triggered when events are more than 2**31 ms
17270 apart (about 25 days). (Bug#8664)
17272 * xselect.c (last_event_timestamp): Remove duplicate decl.
17273 (x_own_selection): Remove needless cast to unsigned long.
17275 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
17276 that always fit in int. Use a sentinel instead of a counter, to
17277 avoid a temp and to allay GCC's concerns about possible int overflow.
17278 * frame.h (struct frame): Use int for menu_bar_items_used
17279 instead of EMACS_INT, since it always fits in int.
17281 * menu.c (grow_menu_items): Check for int overflow.
17283 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
17285 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
17286 Before, the code was not consistent. These values cannot exceed
17287 2**31 - 1 so there's no need to make them unsigned.
17288 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
17289 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
17290 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
17292 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
17294 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
17295 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
17296 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
17297 presumably because the widths might not match.
17299 * window.c (size_window): Avoid needless test at loop start.
17301 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
17303 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
17305 2011-05-12 Drew Adams <drew.adams@oracle.com>
17307 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
17309 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17311 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
17312 `width' to `bar_area_x' and `bar_area_width', respectively.
17313 (x_scroll_run): Take account of fringe background extension.
17315 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
17316 Rename local vars `left' and `width' to `bar_area_x' and
17317 `bar_area_width', respectively.
17318 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
17319 background extension.
17321 2011-05-10 Jim Meyering <meyering@redhat.com>
17323 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
17325 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
17327 * image.c (Finit_image_library): Return t for built-in image types,
17328 like pbm and xbm. (Bug#8640)
17330 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
17332 * w32menu.c (set_frame_menubar): Fix submenu allocation.
17334 2011-05-07 Eli Zaretskii <eliz@gnu.org>
17336 * w32console.c (Fset_screen_color): Doc fix.
17337 (Fget_screen_color): New function.
17338 (syms_of_ntterm): Defsubr it.
17340 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
17341 unlink the temporary file if Fcall_process didn't create it in the
17343 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
17344 child process will be redirected to a file specified with `:file'.
17345 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
17346 cue to call_process_cleanup not to close that handle.
17348 2011-05-07 Ben Key <bkey76@gmail.com>
17350 * makefile.w32-in: The bootstrap-temacs rule now makes use of
17351 one of two shell specific rules, either bootstrap-temacs-CMD or
17352 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
17353 to the previous implementation of the bootstrap-temacs rule.
17354 The bootstrap-temacs-CMD rule is similar to the previous
17355 implementation of the bootstrap-temacs rule except that it
17356 makes use of the ESC_CFLAGS variable instead of the CFLAGS
17359 These changes, along with some changes to nt/configure.bat,
17360 nt/gmake.defs, and nt/nmake.defs, are required to extend my
17361 earlier fix to add support for --cflags and --ldflags options
17362 that include quotes so that it works whether make uses cmd or
17365 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
17367 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
17368 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
17370 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
17371 a string. Handle both cases.
17372 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
17373 (Fdbus_register_method): Use Qinvalid_function.
17375 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
17377 * makefile.w32-in: Update dependencies.
17378 (LISP_H): Add inttypes.h and stdin.h.
17379 (PROCESS_H): Add unistd.h.
17381 2011-05-06 Eli Zaretskii <eliz@gnu.org>
17383 * lread.c: Include limits.h (fixes the MS-Windows build broken by
17384 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
17386 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
17388 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
17390 * term.c (vfatal): Remove stray call to va_end.
17391 It's not needed and the C Standard doesn't allow it here anyway.
17393 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
17394 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
17396 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
17399 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
17401 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
17403 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
17405 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
17407 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
17409 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
17410 * charset.c (Fdefine_charset_internal): Don't initialize
17411 charset.code_space[15]. The value was garbage, on hosts with
17412 32-bit int (Bug#8600).
17414 * lread.c (read_integer): Be more consistent with string-to-number.
17415 Use string_to_number to do the actual conversion; this avoids
17416 rounding errors and fixes some other screwups. Without this fix,
17417 for example, #x1fffffffffffffff was misread as -2305843009213693952.
17418 (digit_to_number): Move earlier, for benefit of read_integer.
17419 Return -1 if the digit is out of range for the base, -2 if it is
17420 not a digit in any supported base. (Bug#8602)
17422 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
17424 * dispnew.c (scrolling_window): Return 1 if we scrolled,
17425 to match comment at start of function. This also removes a
17426 GCC warning about overflow in a 32+64-bit port.
17428 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
17430 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
17431 Reported by Stefan Monnier in
17432 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
17433 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
17434 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
17436 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
17437 (EMACS_UINTPTR): Likewise, with uintptr_t.
17439 * lisp.h: Prefer 64-bit EMACS_INT if available.
17440 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
17441 on 32-bit hosts that have 64-bit int, so that they can access
17443 However, temporarily disable this change unless the temporary
17444 symbol WIDE_EMACS_INT is defined.
17446 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
17448 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
17449 This removes an assumption that EMACS_INT and long are the same
17450 width as pointers. The assumption is true for Emacs porting targets
17451 now, but we want to make other targets possible.
17452 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
17453 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
17454 In the rest of the code, change types of integers that hold casted
17455 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
17456 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
17457 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
17458 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
17459 No need to cast type when ORing.
17460 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
17461 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
17462 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
17463 assume EMACS_INT is the same width as char *.
17464 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
17465 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
17466 Remove no-longer-needed casts.
17467 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
17468 (xg_tool_bar_help_callback, xg_make_tool_item):
17469 Use EMACS_INTPTR to hold an integer
17470 that will be cast to void *; this can avoid a GCC warning
17471 if EMACS_INT is not the same width as void *.
17472 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
17473 * xdisp.c (display_echo_area_1, resize_mini_window_1):
17474 (current_message_1, set_message_1):
17475 Use a local to convert to proper width without a cast.
17476 * xmenu.c (dialog_selection_callback): Likewise.
17478 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
17479 Also, don't assume VALBITS / RAND_BITS is less than 5,
17480 and don't rely on undefined behavior when shifting a 1 left into
17482 * lisp.h (get_random): Change signature to match.
17484 * lread.c (hash_string): Use size_t, not int, for hash computation.
17485 Normally we prefer signed values; but hashing is special, because
17486 it's better to use unsigned division on hash table sizes so that
17487 the remainder is nonnegative. Also, size_t is the natural width
17488 for hashing into memory. The previous code used 'int', which doesn't
17489 retain enough info to hash well into very large tables.
17490 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
17492 * dbusbind.c: Don't possibly lose pointer info when converting.
17493 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
17494 Use XPNTR rather than XHASH, so that the high-order bits of
17495 the pointer aren't lost when converting through void *.
17497 * eval.c (Fautoload): Don't double-shift a pointer.
17499 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
17501 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
17503 * gnutls.c (DEF_GNUTLS_FN):
17504 * image.c (DEF_IMGLIB_FN): Make function pointers static.
17506 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
17508 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
17511 2011-05-05 Eli Zaretskii <eliz@gnu.org>
17513 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
17514 New version that can reserve upto 2GB of heap space.
17516 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
17518 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).

17522 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
17523 `gnutls_certificate_set_x509_key_file'.
17525 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
17527 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
17528 Update dependencies.
17530 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
17532 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
17533 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
17534 Remove unused parameter `fildes'.
17535 * process.c (read_process_output, send_process): Don't pass it.
17537 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
17539 Fix previous change: the library cache is defined in w32.c.
17540 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
17541 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
17543 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
17545 Implement dynamic loading of GnuTLS on Windows.
17547 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
17548 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
17549 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
17552 * gnutls.c (Qgnutls_dll): Define.
17553 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
17554 (gnutls_*): Declare function pointers.
17555 (init_gnutls_functions): New function to initialize function pointers.

17558 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
17559 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
17560 (emacs_gnutls_write, emacs_gnutls_read)
17561 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
17562 (Fgnutls_available_p): New function.
17563 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

17575 * w32.c (QCloaded_from, Vlibrary_cache): Define.
17576 (w32_delayed_load): Move from image.c. When loading a library, record
17577 its filename in the :loaded-from property of the library id.
17578 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
17579 Initialize and staticpro them.
17580 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
17582 * process.c: Include lisp.h before w32.h, not after.
17583 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
17584 instead of gnutls_record_check_pending.
17586 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
17588 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
17590 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
17591 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
17594 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
17596 * xterm.c (x_set_frame_alpha): Do not set property on anything
17597 else than FRAME_X_OUTER_WINDOW (Bug#8608).
17599 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
17601 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
17603 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
17605 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

17619 * sysdep.c (wait_for_termination_1): Make static.
17620 (wait_for_termination, interruptible_wait_for_termination):
17621 Move after wait_for_termination_1.
17623 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
17625 * sysdep.c (interruptible_wait_for_termination): New function
17626 which is like wait_for_termination, but allows keyboard
17629 * callproc.c (Fcall_process): Add (:file "file") as an option for
17631 (Fcall_process_region): Ditto.
17633 2011-04-30 Eli Zaretskii <eliz@gnu.org>
17635 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
17636 rather than `XVECTOR (FOO)->size'.
17638 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
17639 inttypes.h, as a gnulib replacement is used if it not available in
17642 2011-04-21 Eli Zaretskii <eliz@gnu.org>
17644 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
17645 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
17646 of MOST_POSITIVE_FIXNUM. (Bug#8528)
17648 * coding.c (coding_alloc_by_realloc): Error out if destination
17649 will grow beyond MOST_POSITIVE_FIXNUM.
17650 (decode_coding_emacs_mule): Abort if there isn't enough place in
17651 charbuf for the composition carryover bytes. Reserve an extra
17652 space for up to 2 characters produced in a loop.

17661 %llo or %llx format is passed. (Bug#8545)
17663 * window.c (window_scroll_line_based): Use a marker instead of
17664 simple variables to record original value of point. (Bug#7952)
17666 * doprnt.c (doprnt): Fix the case where a multibyte sequence
17667 produced by %s or %c overflows available buffer space. (Bug#8545)
17669 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>

17704 2011-04-27 Eli Zaretskii <eliz@gnu.org>
17706 Improve `doprnt' and its usage. (Bug#8545)
17707 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
17708 `format_end'. Remove support for %l as a conversion specifier.
17709 Don't use xrealloc. Improve diagnostics when the %l size modifier
17710 is used. Update the commentary.
17712 * eval.c (verror): Simplify calculation of size_t.
17714 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
17717 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
17719 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
17722 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
17724 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
17725 This makes this file independent of the recent pseudovector change.
17727 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
17729 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
17731 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
17732 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
17733 Remove unused local.
17734 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
17736 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
17737 GCC 4.6.0 optimizes based on type-based alias analysis.
17738 For example, if b is of type struct buffer * and v of type struct
17739 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
17740 != &v->size, and therefore "v->size = 1; b->size = 2; return
17741 v->size;" must therefore return 1. This assumption is incorrect
17742 for Emacs, since it type-puns struct Lisp_Vector * with many other
17743 types. To fix this problem, this patch adds a new type struct
17744 vectorlike_header that documents the constraints on layout of vectors
17745 and pseudovectors, and helps optimizing compilers not get fooled
17746 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
17747 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
17748 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
17750 (XSETPVECTYPE): Rewrite in terms of new macro.
17751 (XSETPVECTYPESIZE): New macro, specifying both type and size.
17752 This is a bit clearer, and further avoids the possibility of
17753 undesirable aliasing.
17754 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
17755 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
17756 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
17757 since Lisp_Subr is a special case (no "next" field).
17758 (ASIZE): Now uses header.size rather than size.
17759 All previous uses of XVECTOR (foo)->size replaced to use this macro,
17760 to avoid the hassle of writing XVECTOR (foo)->header.size.
17761 (struct vectorlike_header): New type.
17762 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
17763 object, to help avoid aliasing.
17764 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
17765 (SUBRP): Likewise, since Lisp_Subr is a special case.
17766 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
17767 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
17768 (struct Lisp_Hash_Table): Combine first two members into a single
17769 struct vectorlike_header member. All uses of "size" and "next" members
17770 changed to be "header.size" and "header.next".
17771 * buffer.h (struct buffer): Likewise.
17772 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
17773 * frame.h (struct frame): Likewise.
17774 * process.h (struct Lisp_Process): Likewise.
17775 * termhooks.h (struct terminal): Likewise.
17776 * window.c (struct save_window_data, struct saved_window): Likewise.
17777 * window.h (struct window): Likewise.
17778 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
17779 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
17780 * buffer.c (init_buffer_once): Likewise.
17781 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
17783 * process.c (Fformat_network_address): Use local var for size,
17786 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
17788 Make the Lisp reader and string-to-float more consistent (Bug#8525)
17789 * data.c (atof): Remove decl; no longer used or needed.
17790 (digit_to_number): Move to lread.c.
17791 (Fstring_to_number): Use new string_to_number function, to be
17792 consistent with how the Lisp reader treats infinities and NaNs.
17793 Do not assume that floating-point numbers represent EMACS_INT
17794 without losing information; this is not true on most 64-bit hosts.
17795 Avoid double-rounding errors, by insisting on integers when
17796 parsing non-base-10 numbers, as the documentation specifies.
17797 * lisp.h (string_to_number): New decl, replacing ...
17798 (isfloat_string): Remove.
17799 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
17800 (read1): Do not accept +. and -. as integers; this
17801 appears to have been a coding error. Similarly, do not accept
17802 strings like +-1e0 as floating point numbers. Do not report
17803 overflow for integer overflows unless the base is not 10 which
17804 means we have no simple and reliable way to continue.
17805 Break out the floating-point parsing into a new
17806 function string_to_number, so that Fstring_to_number parses
17807 floating point numbers consistently with the Lisp reader.
17808 (digit_to_number): Move here from data.c. Make it static inline.
17809 (E_CHAR, EXP_INT): Remove, replacing with ...
17810 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
17811 (string_to_number): New function, replacing isfloat_string.
17812 This function checks for valid syntax and produces the resulting
17813 Lisp float number too. Rework it so that string-to-number
17814 no longer mishandles examples like "1.0e+". Use strtoumax,
17815 so that overflow for non-base-10 numbers is reported only when
17816 there's no portable and simple way to convert to floating point.
17818 * textprop.c (set_text_properties_1): Rewrite for clarity,
17819 and to avoid GCC warning about integer overflow.
17821 * intervals.h (struct interval): Use EMACS_INT for members
17822 where EMACS_UINT might cause problems. See
17823 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
17824 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
17825 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
17827 (offset_intervals): Tell GCC not to worry about length overflow
17828 when negating a negative length.
17830 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
17831 (overrun_check_free): Likewise.
17833 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
17834 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
17837 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
17838 (gnutls_make_error): Rename local to avoid shadowing.
17839 (gnutls_emacs_global_deinit): ifdef out; not used.
17840 (Fgnutls_boot): Use const for pointer to readonly storage.
17841 Comment out unused local. Fix pointer signedness problems.
17843 * lread.c (openp): Don't stuff size_t into an 'int'.
17844 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
17845 about possible signed overflow.
17847 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
17848 (GDK_KEY_g): Don't define if already defined.
17849 (xg_prepare_tooltip): Avoid pointer signedness problem.
17850 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
17852 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
17853 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
17855 * xfns.c (Fx_window_property): Simplify a bit,
17856 to make a bit faster and to avoid GCC 4.6.0 warning.
17857 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
17859 * fns.c (internal_equal): Don't assume size_t fits in int.
17861 * alloc.c (compact_small_strings): Tighten assertion a little.
17863 Replace pEd with more-general pI, and fix some printf arg casts.
17864 * lisp.h (pI): New macro, generalizing old pEd macro to other
17865 conversion specifiers. For example, use "...%"pI"d..." rather
17866 than "...%"pEd"...".
17867 (pEd): Remove. All uses replaced with similar uses of pI.
17868 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
17869 * alloc.c (check_pure_size): Don't overflow by converting size to int.
17870 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
17871 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
17872 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
17873 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
17874 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
17876 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
17877 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
17878 * print.c (safe_debug_print, print_object): Likewise.
17879 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
17881 Use pI instead of if-then-else-abort. Use %p to avoid casts,
17882 avoiding the 0 flag, which is not portable.
17883 * process.c (Fmake_network_process): Use pI to avoid cast.
17884 * region-cache.c (pp_cache): Likewise.
17885 * xdisp.c (decode_mode_spec): Likewise.
17886 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
17887 behavior on 64-bit hosts with printf arg.
17888 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
17889 (x_stop_queuing_selection_requests): Likewise.
17890 (x_get_window_property): Don't truncate byte count to an 'int'
17893 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
17894 here, since it parses constructs like leading '-' and spaces,
17895 which are not wanted; and it overflows with large numbers.
17896 Instead, simply match F[0-9]+, which is what is wanted anyway.
17898 * alloc.c: Remove unportable assumptions about struct layout.
17899 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
17900 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
17901 (allocate_vectorlike, make_pure_vector): Use the new macros,
17902 plus offsetof, to remove unportable assumptions about struct layout.
17903 These assumptions hold on all porting targets that I know of, but
17904 they are not guaranteed, they're easy to remove, and removing them
17905 makes further changes easier.
17907 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
17908 This doesn't fix a bug but makes the code clearer.
17909 (string_overrun_cookie): Now const. Use initializers that
17910 don't formally overflow signed char, to avoid warnings.
17911 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
17912 can cause Emacs to crash when string overrun checking is enabled.
17913 (allocate_buffer): Don't assume sizeof (struct buffer) is a
17914 multiple of sizeof (EMACS_INT); it need not be, if
17915 alignof(EMACS_INT) < sizeof (EMACS_INT).
17916 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
17918 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

17925 supposed to be handshaking. (Bug#8556)
17926 Reported by Paul Eggert <eggert@cs.ucla.edu>.
17928 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

17939 (check_string_free_list): Convert to standard C.
17941 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
17943 * w32.c (emacs_gnutls_push): Fix typo.
17945 2011-04-25 Eli Zaretskii <eliz@gnu.org>
17947 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
17948 "cast to pointer from integer of different size".
17950 Improve doprnt and its use in verror. (Bug#8545)
17951 * doprnt.c (doprnt): Document the set of format control sequences
17952 supported by the function. Use SAFE_ALLOCA instead of always
17955 * eval.c (verror): Don't limit the buffer size at size_max-1, that
17956 is one byte too soon. Don't use xrealloc; instead xfree and
17959 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
17961 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
17964 * gnutls.c: Renamed global_initialized to
17965 gnutls_global_initialized. Added internals for the
17966 :verify-hostname-error, :verify-error, and :verify-flags
17967 parameters of `gnutls-boot' and documented those parameters in the
17968 docstring. Start callback support.
17969 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
17970 unless a fatal error occurred. Call gnutls_alert_send_appropriate
17971 on error. Return error code.

18043 * doprnt.c: Include limits.h.
18044 (SIZE_MAX): New macro.
18045 (doprnt): Return a size_t value. 2nd arg is now size_t.
18046 Many local variables are now size_t instead of int or unsigned.
18047 Improve overflow protection. Support `l' modifier for integer
18048 conversions. Support %l conversion. Don't assume an EMACS_INT
18049 argument for integer conversions and for %c.
18051 * lisp.h (doprnt): Restore prototype.
18053 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
18054 $(SRC)/character.h.
18056 * Makefile.in (base_obj): Add back doprnt.o.
18058 * deps.mk (doprnt.o): Add back prerequisites.
18059 (callint.o): Depend on character.h.
18061 * eval.c (internal_lisp_condition_case): Include the handler
18062 representation in the error message.

18068 * callint.c (Fcall_interactively): When displaying error message
18069 about invalid control letter, pass the character's codepoint, not
18070 a pointer to its multibyte form. Improve display of the character
18071 in octal and display also its hex code.
18073 * character.c (char_string): Use %x to display the (unsigned)
18074 codepoint of an invalid character, to avoid displaying a bogus
18077 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
18078 `error', not SYMBOL_NAME itself.
18080 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
18081 character arguments to `error'.
18083 * charset.c (check_iso_charset_parameter): Fix incorrect argument
18084 to `error' in error message about FINAL_CHAR argument. Make sure
18085 FINAL_CHAR is a character, and use %c when it is passed as

18156 * dispextern.h (struct redisplay_interface): Rename param
18157 to avoid shadowing.
18158 * termhooks.h (struct terminal): Likewise.

18162 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
18164 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
18167 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
18168 so that we aren't warned about unused symbols.
18170 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
18172 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).

18185 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
18187 * xmenu.c (menu_help_callback): Pointer type fixes.

18205 compatible char. Avoid the old compiler warnings about
18206 out-of-range initializers by using, for example, '\xab' rather
18209 * xgselect.c (xgselect_initialize): Check vs interface
18210 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).

18275 * nsfont.m: Fixed bugs in ns_get_family and
18276 ns_descriptor_to_entity that were caused by using free to
18277 deallocate memory blocks that were allocated by xmalloc (via
18278 xstrdup). This caused Emacs to crash when compiled with
18279 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
18280 --enable-checking=xmallocoverrun). xfree is now used to
18281 deallocate these memory blocks.

18677 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
18678 * xmenu.c, xselect.c:
18679 Declare Q* vars static if they are not used in other modules.
18680 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
18681 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
18682 Remove decls of unexported vars.
18683 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
18685 * lisp.h (DEFINE_FUNC): Make sname 'static'.
18687 Make Emacs functions such as Fatom 'static' by default.
18688 This makes it easier for human readers (and static analyzers)
18689 to see whether these functions can be called from other modules.
18690 DEFUN now defines a static function. To make the function external
18691 so that it can be used in other C modules, use the new macro DEFUE.
18692 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
18693 (Finit_image_library):
18694 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
18695 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
18696 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
18697 Remove decls, since these functions are now static.
18698 (Funintern, Fget_internal_run_time): New decls, since these functions
18699 were already external.
18701 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
18702 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

18708 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
18709 Mark functions with DEFUE instead of DEFUN,
18710 if they are used in other modules.
18711 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
18712 decls for now-static functions.
18713 * buffer.h (Fdelete_overlay): Remove decl.
18714 * callproc.c (Fgetenv_internal): Mark as internal.
18715 * composite.c (Fremove_list_of_text_properties): Remove decl.

18719 * doc.c (Fdocumntation_property): New forward static decl.
18720 * eval.c (Ffetch_bytecode): New forward static decl.
18721 (Funintern): Remove extern decl; now in .h file where it belongs.
18722 * fileio.c (Fmake_symbolic_link): New forward static decl.
18723 * image.c (Finit_image_library): New forward static decl.
18724 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
18725 * intervals.h (Fprevious_property_change):
18726 (Fremove_list_of_text_properties): Remove decls.
18727 * keyboard.c (Fthis_command_keys): Remove decl.
18728 (Fcommand_execute): New forward static decl.
18729 * keymap.c (Flookup_key): New forward static decl.
18730 (Fcopy_keymap): Now static.
18731 * keymap.h (Flookup_key): Remove decl.

18744 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
18746 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
18749 2011-04-13 Eli Zaretskii <eliz@gnu.org>
18751 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
18752 when at ZV. (Bug#8487)
18754 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
18756 * charset.c (Fclear_charset_maps): Use xfree instead of free.
18758 * keyboard.c (parse_tool_bar_item): Likewise.
18759 * sound.c (sound_cleanup, alsa_close): Likewise.
18760 * termcap.c (tgetent): Likewise.
18761 * xfns.c (x_default_font_parameter): Likewise.
18762 * xsettings.c (read_and_apply_settings): Likewise.
18764 * alloc.c (overrun_check_malloc, overrun_check_realloc)
18765 (overrun_check_free): Protoize.
18767 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
18769 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
18770 since callers should never pass a negative size.
18771 Change the signature to match that of plain 'read' and 'write'; see
18772 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
18773 * lisp.h: Update prototypes of emacs_write and emacs_read.
18775 2011-04-11 Eli Zaretskii <eliz@gnu.org>
18777 * xdisp.c (redisplay_window): Don't try to determine the character
18778 position of the scroll margin if the window start point w->startp
18779 is outside the buffer's accessible region. (Bug#8468)
18781 2011-04-10 Eli Zaretskii <eliz@gnu.org>
18783 Fix write-region and its subroutines for buffers > 2GB.
18784 * fileio.c (a_write, e_write): Modify declaration of arguments and
18785 local variables to support buffers larger than 2GB.
18786 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
18788 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
18789 argument, local variables, and return value.
18791 * lisp.h: Update prototypes of emacs_write and emacs_read.
18793 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
18795 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
18797 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
18799 Fix more problems found by GCC 4.6.0's static checks.
18801 * xdisp.c (vmessage): Use a better test for character truncation.
18803 * charset.c (load_charset_map): <, not <=, for optimization,
18804 and to avoid potential problems with integer overflow.
18805 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
18806 * casetab.c (set_identity, shuffle): Likewise.
18807 * editfns.c (Fformat): Likewise.
18808 * syntax.c (skip_chars): Likewise.
18810 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
18811 This also lets GCC 4.6.0 generate slightly better loop code.
18813 * callint.c (Fcall_interactively): <, not <=, for optimization.
18814 (Fcall_interactively): Count the number of arguments produced,
18815 not the number of arguments given. This is simpler and lets GCC
18816 4.6.0 generate slightly better code.
18818 * ftfont.c: Distingish more carefully between FcChar8 and char.
18819 The previous code passed unsigned char * to a functions like
18820 strlen and xstrcasecmp that expect char *, which does not
18821 conform to the C standard.
18822 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
18823 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
18824 char * when the C standard requires it.
18826 * keyboard.c (read_char): Remove unused var.
18828 * eval.c: Port to Windows vsnprintf (Bug#8435).
18829 Include <limits.h>.
18830 (SIZE_MAX): Define if the headers do not.
18831 (verror): Do not give up if vsnprintf returns a negative count.
18832 Instead, grow the buffer. This ports to Windows vsnprintf, which
18833 does not conform to C99. Problem reported by Eli Zaretskii.
18834 Also, simplify the allocation scheme, by avoiding the need for
18835 calling realloc, and removing the ALLOCATED variable.
18837 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
18839 Remove invocations of doprnt, as Emacs now uses vsnprintf.
18840 But keep the doprint source code for now, as we might revamp it
18841 and use it again (Bug#8435).
18842 * lisp.h (doprnt): Remove.
18843 * Makefile.in (base_obj): Remove doprnt.o.
18844 * deps.mk (doprnt.o): Remove.
18846 error: Print 32- and 64-bit integers portably (Bug#8435).
18847 Without this change, on typical 64-bit hosts error ("...%d...", N)
18848 was used to print both 32- and 64-bit integers N, which relied on
18849 undefined behavior.
18850 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
18851 * lisp.h (error, verror): Mark as printf-like functions.
18852 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
18853 Report overflow in size calculations when allocating printf buffer.
18854 Do not truncate output string at its first null byte.
18855 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
18856 Truncate the output at a character boundary, since vsnprintf does not
18858 * charset.c (check_iso_charset_parameter): Convert internal
18859 character to string before calling 'error', since %c now has the
18861 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
18862 overflow when computing char to be passed to 'error'. Do not
18863 pass Lisp_Object to 'error'; pass the integer instead.
18864 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
18865 formatted with plain %d.
18867 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
18869 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
18871 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
18873 * xterm.c (x_catch_errors): Remove duplicate declaration.
18875 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
18877 * xdisp.c, lisp.h (message_nolog): Remove; unused.
18879 2011-04-10 Jim Meyering <meyering@redhat.com>
18881 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
18882 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
18883 return ssize_t not "int", and use size_t as the buffer length.
18884 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
18885 * gnutls.h: Update declarations.
18886 * process.c (read_process_output): Use ssize_t, to match.
18887 (send_process): Likewise.
18889 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
18891 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
18893 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
18895 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
18896 Use unsigned char, to match FcChar8 type definition.
18898 * xterm.c (handle_one_xevent):
18899 * xmenu.c (create_and_show_popup_menu):
18900 * xselect.c (x_decline_selection_request)
18901 (x_reply_selection_request): Avoid type-punned deref of X events.
18903 2011-04-09 Eli Zaretskii <eliz@gnu.org>
18905 Fix some uses of `int' instead of EMACS_INT.
18906 * search.c (string_match_1, fast_string_match)
18907 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
18908 (scan_buffer, find_next_newline_no_quit)
18909 (find_before_next_newline, search_command, Freplace_match)
18910 (Fmatch_data): Make some `int' variables be EMACS_INT.
18912 * xdisp.c (display_count_lines): 3rd argument and return value now
18913 EMACS_INT. All callers changed.
18914 (pint2hrstr): Last argument is now EMACS_INT.
18916 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
18917 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
18918 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
18919 (decode_coding_utf_16, decode_coding_emacs_mule)

18921 (decode_coding_ccl, decode_coding_charset)
18922 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
18923 (decode_coding_iso_2022, decode_coding_emacs_mule)
18924 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
18925 <char_offset, last_offset>: Declare EMACS_INT.

18928 (encode_designation_at_bol, encode_coding_iso_2022)
18929 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
18930 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
18932 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
18933 (encode_invocation_designation): Last argument P_NCHARS is now
18935 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
18936 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
18938 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
18941 * ccl.c (Fccl_execute_on_string): Declare some variables
18944 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
18946 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
18948 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
18950 * process.c (Fformat_network_address): Doc fix.
18952 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
18954 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
18956 2011-04-08 Chong Yidong <cyd@stupidchicken.com>

18959 instead of using internal_with_output_to_temp_buffer.
18960 (Qhelp_form_show): New var.
18961 (syms_of_keyboard): Use DEFSYM macro.
18963 * print.c (internal_with_output_to_temp_buffer): Function deleted.

18967 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
18969 * process.c (Flist_processes): Remove to Lisp.
18970 (list_processes_1): Delete.

18974 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
18976 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
18978 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
18980 Fix more problems found by GCC 4.6.0's static checks.

18984 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
18986 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
18988 * xdisp.c (vmessage): Mark as a printf-like function.
18990 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
18992 * sound.c (sound_warning): Don't crash if arg contains a printf format.

18997 to system-supplied API.
18999 * eval.c (Fsignal): Remove excess argument to 'fatal'.
19001 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
19002 This avoids several warnings with gcc -Wstrict-overflow.
19003 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
19004 directly, rather than having caller test rule sign. This avoids
19005 some unnecessary tests.
19006 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
19007 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
19008 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
19010 * xfont.c (xfont_text_extents): Remove var that was set but not used.
19011 (xfont_open): Avoid unnecessary tests.
19013 * composite.c (composition_gstring_put_cache): Use unsigned integer.

19022 by using the new macro.
19024 * textprop.c (set_text_properties_1): Change while to do-while,
19025 since the condition is always true at first.
19027 * intervals.c (graft_intervals_into_buffer): Mark var as used.
19028 (interval_deletion_adjustment): Return unsigned value.
19031 * process.c (list_processes_1, create_pty, read_process_output):

19044 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
19045 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
19047 * print.c (print_error_message): Avoid int overflow.
19049 * font.c (font_list_entities): Redo for clarity,
19050 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
19052 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
19053 (font_score): Avoid potential overflow in diff calculation.
19055 * fns.c (substring_both): Remove var that is set but not used.
19056 (sxhash): Redo loop for clarity and to avoid wraparound warning.
19058 * eval.c (funcall_lambda): Rename local to avoid shadowing.
19060 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
19061 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
19062 can always succeed if overflow has undefined behavior.
19064 * search.c (boyer_moore, wordify): Remove vars set but not used.
19065 (wordify): Omit three unnecessary tests.
19067 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
19068 All callers changed. This avoids the need for an unused var.
19070 * casefiddle.c (casify_region): Remove var that is set but not used.
19072 * dired.c (file_name_completion): Remove var that is set but not used.

19076 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
19077 (Finsert_file_contents): Remove unnecessary code checking fd.
19079 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
19080 Check for integer overflow on size calculations.
19082 * buffer.c (Fprevious_overlay_change): Remove var that is set
19085 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
19086 Remove vars that are set but not used.
19087 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
19088 (timer_check_2): Mark vars as initialized.
19090 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
19092 * image.c (lookup_image): Remove var that is set but not used.
19093 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
19095 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
19096 that are set but not used.
19098 * xfns.c (make_invisible_cursor): Don't return garbage
19099 if XCreateBitmapFromData fails (Bug#8410).
19101 * xselect.c (x_get_local_selection, x_handle_property_notify):
19102 Remove vars that are set but not used.
19104 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
19105 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
19107 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
19108 Remove var that is set but not used.
19109 (scroll_bar_windows_size): Now size_t, not int.
19110 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
19111 Check for overflow.
19113 * xfaces.c (realize_named_face): Remove vars that are set but not used.
19114 (map_tty_color) [!defined MSDOS]: Likewise.
19116 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
19118 * coding.c: Remove vars that are set but not used.
19119 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.

19126 that is set but not used.
19128 * print.c (print_object): Remove var that is set but not used.
19130 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
19131 The gnulib version avoids calling malloc in the usual case,
19132 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
19133 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
19134 * filelock.c (current_lock_owner): Likewise.
19135 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
19136 * sysdep.c: Include allocator.h, careadlinkat.h.
19137 (emacs_no_realloc_allocator): New static constant.
19138 (emacs_readlink): New function.
19139 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
19140 ../lib/careadlinkat.h.
19142 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
19144 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the

19166 do not dereference NULL upon failed strdup
19167 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
19168 (ns_get_family): Likewise.
19170 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
19172 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
19174 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
19176 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
19179 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
19181 Add lexical binding.
19183 * window.c (Ftemp_output_buffer_show): New fun.
19184 (Fsave_window_excursion):
19185 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.

19190 Bind Qinternal_interpreter_environment.
19191 (Feval_buffer): Bind Qlexical_binding.
19192 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
19194 (syms_of_lread): Declare `lexical-binding'.
19196 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
19198 * keyboard.c (eval_dyn): New fun.
19199 (menu_item_eval_property): Use it.
19201 * image.c (parse_image_spec): Use Ffunctionp.
19203 * fns.c (concat, mapcar1): Accept byte-code-functions.
19205 * eval.c (Fsetq): Handle lexical vars.
19206 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
19207 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
19208 (FletX, Flet): Obey lexical binding.
19209 (Fcommandp): Handle closures.
19210 (Feval): New `lexical' arg.
19211 (eval_sub): New function extracted from Feval. Use it almost
19212 everywhere where Feval was used. Look up vars in lexical env.
19214 (Ffunctionp): Move from subr.el.
19215 (Ffuncall): Handle closures.
19216 (apply_lambda): Remove `eval_flags'.
19217 (funcall_lambda): Handle closures and new byte-code-functions.
19218 (Fspecial_variable_p): New function.
19219 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
19220 but without exporting it to Lisp.
19222 * doc.c (Fdocumentation, store_function_docstring):
19223 * data.c (Finteractive_form): Handle closures.
19225 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
19228 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
19230 (exec_byte_code): New function extracted from Fbyte_code to handle new
19231 calling convention for byte-code-functions. Add new byte-codes.
19233 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
19235 * alloc.c (Fmake_symbol): Init new `declared_special' field.
19237 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
19239 * xdisp.c (redisplay_internal): Fix prototype.
19241 2011-03-31 Eli Zaretskii <eliz@gnu.org>
19243 * xdisp.c (SCROLL_LIMIT): New macro.
19244 (try_scrolling): Use it when setting scroll_limit.
19245 Limit scrolling to 100 screen lines.
19246 (redisplay_window): Even when falling back on "recentering",
19247 position point in the window according to scroll-conservatively,
19248 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
19250 (try_scrolling): When point is above the window, allow searching
19251 as far as scroll_max, or one screenful, to compute vertical
19252 distance from PT to the scroll margin position. This prevents
19253 try_scrolling from unnecessarily failing when
19254 scroll-conservatively is set to a value slightly larger than the
19255 window height. Clean up the case of PT below the margin at bottom
19256 of window: scroll_max can no longer be INT_MAX. When aggressive
19257 scrolling is in use, don't let point enter the opposite scroll
19258 margin as result of the scroll.
19259 (syms_of_xdisp) <scroll-conservatively>: Document the
19260 threshold of 100 lines for never-recentering scrolling.

19267 (message_log_check_duplicate): Remove parameters `prev_bol' and
19268 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
19269 (redisplay_internal): Remove parameter `preserve_echo_area',
19270 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
19272 * indent.c (Fvertical_motion):
19273 * window.c (window_scroll_pixel_based, Frecenter):
19274 Don't pass `need_y_p' to `move_it_by_lines'.
19276 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
19278 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
19279 steal a few bits to be more compact.
19280 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
19281 Remove unneeded casts.
19283 * bytecode.c (Fbyte_code): CAR and CDR can GC.
19285 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
19287 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
19288 binding" message (bug#7967).
19290 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
19292 Fix more problems found by GCC 4.6.0's static checks.
19294 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
19295 Remove unused local var.
19297 * editfns.c (Fmessage_box): Remove unused local var.
19299 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
19300 (note_mode_line_or_margin_highlight, note_mouse_highlight):
19301 Omit unused local vars.
19302 * window.c (shrink_windows): Omit unused local var.
19303 * menu.c (digest_single_submenu): Omit unused local var.
19304 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
19305 Omit unused local var.
19307 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
19308 Don't assume string length fits in int.
19309 (keyremap_step, read_key_sequence): Use size_t for sizes.
19310 (read_key_sequence): Don't check last_real_key_start redundantly.
19312 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
19313 instead of alloca (Bug#8344).
19315 * eval.c (Fbacktrace): Don't assume nargs fits in int.
19316 (Fbacktrace_frame): Don't assume nframes fits in int.
19318 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

19325 * cm.c (calccost): Turn while-do into do-while, for clarity.
19327 * keyboard.c (syms_of_keyboard): Use the same style as later
19328 in this function when indexing through an array. This also
19329 works around GCC bug 48267.
19331 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
19333 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
19335 * chartab.c (sub_char_table_ref_and_range): Redo for slight
19336 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
19338 * keyboard.c, keyboard.h (num_input_events): Now size_t.
19339 This avoids undefined behavior on integer overflow, and is a bit
19340 more convenient anyway since it is compared to a size_t variable.
19342 Variadic C functions now count arguments with size_t, not int.
19343 This avoids an unnecessary limitation on 64-bit machines, which
19344 caused (substring ...) to crash on large vectors (Bug#8344).

19354 * fns.c (concat): Likewise.
19355 * frame.c (x_set_frame_parameters): Likewise.
19356 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
19357 0 if not found, not -1. All callers changed.
19359 * alloc.c (garbage_collect): Don't assume stack size fits in int.
19360 (stack_copy_size): Now size_t, not int.
19361 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
19363 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
19365 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
19366 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

19382 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
19383 don't set the hook to nil, but remove the offending function instead.
19384 (Qcommand_hook_internal): Remove, unused.
19385 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
19386 Vcommand_hook_internal.
19388 * eval.c (enum run_hooks_condition): Remove.
19389 (funcall_nil, funcall_not): New functions.
19390 (run_hook_with_args): Call each function through a `funcall' argument.

19404 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.

19554 2011-03-23 Julien Danjou <julien@danjou.info>
19556 * term.c (Fsuspend_tty, Fresume_tty):
19557 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
19558 * window.c (temp_output_buffer_show):
19559 * insdel.c (signal_before_change):
19560 * frame.c (Fhandle_switch_frame):
19561 * fileio.c (Fdo_auto_save):
19562 * emacs.c (Fkill_emacs):
19563 * editfns.c (save_excursion_restore):
19564 * cmds.c (internal_self_insert):
19565 * callint.c (Fcall_interactively):
19566 * buffer.c (Fkill_all_local_variables):
19567 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
19569 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
19570 unconditionally since it does the check itself.
19572 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
19574 Fix more problems found by GCC 4.5.2's static checks.
19576 * coding.c (encode_coding_raw_text): Avoid unnecessary test
19577 the first time through the loop, since we know p0 < p1 then.
19578 This also avoids a gcc -Wstrict-overflow warning.
19580 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
19581 leading to a memory leak, possible in functions like
19582 load_charset_map_from_file that can allocate an unbounded number
19583 of objects (Bug#8318).
19585 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
19586 that could (at least in theory) be that large.
19588 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
19589 This is less likely to overflow, and avoids undefined behavior if
19590 overflow does occur. All callers changed. Use strtoul to scan
19591 for the unsigned long integer.
19592 (pint2hrstr): Simplify and tune code slightly.
19593 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
19595 * scroll.c (do_scrolling): Work around GCC bug 48228.
19596 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
19598 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
19599 This also avoids a warning with gcc -Wstrict-overflow.
19600 (validate_x_resource_name): Simplify count usage.
19601 This also avoids a warning with gcc -Wstrict-overflow.
19603 * fileio.c (Fcopy_file): Report error if fchown or fchmod
19606 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
19608 * process.c (Fmake_network_process): Use socklen_t, not int,
19609 where POSIX says socklen_t is required in portable programs.
19610 This fixes a porting bug on hosts like 64-bit HP-UX, where
19611 socklen_t is wider than int (Bug#8277).
19612 (Fmake_network_process, server_accept_connection):
19613 (wait_reading_process_output, read_process_output):
19616 * process.c: Rename or move locals to avoid shadowing.
19617 (list_processes_1, Fmake_network_process):
19618 (read_process_output_error_handler, exec_sentinel_error_handler):
19619 Rename or move locals.
19620 (Fmake_network_process): Define label "retry_connect" only if needed.
19621 (Fnetwork_interface_info): Fix pointer signedness.
19622 (process_send_signal): Add cast to avoid pointer signedness problem.
19623 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
19624 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
19626 Make tparam.h and terminfo.c consistent.
19627 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
19628 Include tparam.h instead, since it declares them.
19629 * cm.h (PC): Remove extern decl; tparam.h now does this.
19630 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
19631 * terminfo.c: Include tparam.h, to check interfaces.
19632 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
19633 (tparam): Adjust signature to match interface in tparam.h;
19634 this removes some undefined behavior. Check that outstring and len
19635 are zero, which they always are with Emacs.
19636 * tparam.h (PC, BC, UP): New extern decls.
19638 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
19639 (xftfont_open): Rename locals to avoid shadowing.
19641 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
19642 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
19643 (OTF_TAG_SYM): Omit macro if not needed.
19644 (ftfont_list): Remove unused local.
19645 (get_adstyle_property, ftfont_pattern_entity):
19646 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
19647 Rename locals to avoid shadowing.

19651 * xml.c (make_dom): Now static.
19653 * composite.c (composition_compute_stop_pos): Rename local to
19655 (composition_reseat_it): Remove unused locals.
19656 (find_automatic_composition, composition_adjust_point): Likewise.
19657 (composition_update_it): Mark var as initialized.
19658 (find_automatic_composition): Mark vars as initialized,
19659 with a FIXME (Bug#8290).
19661 character.h: Rename locals to avoid shadowing.
19662 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
19663 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
19664 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
19665 (BUF_DEC_POS): Be more systematic about renaming local temporaries
19666 to avoid shadowing.
19668 * textprop.c (property_change_between_p): Remove; unused.
19670 * intervals.c (interval_start_pos): Now static.
19672 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

19675 Rename locals to avoid shadowing.
19677 * sound.c (wav_play, au_play, Fplay_sound_internal):
19678 Fix pointer signedness.
19679 (alsa_choose_format): Remove unused local var.
19680 (wav_play): Initialize a variable to 0, to prevent undefined
19681 behavior (Bug#8278).
19683 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
19685 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
19687 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
19688 clobbering (Bug#8298).
19689 * sysdep.c (sys_subshell): Likewise.
19690 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
19692 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
19693 This should get cleaned up, so that child_setup has the
19694 same signature on all platforms.
19696 * callproc.c (call_process_cleanup): Now static.
19697 (relocate_fd): Rename locals to avoid shadowing.
19699 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
19701 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
19702 not to be necessary, and produces flickering.
19704 2011-03-20 Glenn Morris <rgm@gnu.org>
19706 * config.in: Remove file.
19708 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
19710 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
19711 are now in src/globals.h.
19712 (syms_of_minibuf): Remove spurious & from previous change.
19714 2011-03-20 Leo Liu <sdl.web@gmail.com>
19716 * minibuf.c (completing-read-function): New variable.
19717 (completing-read-default): Rename from completing-read.
19718 (completing-read): Call completing-read-function.
19720 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
19722 * xfaces.c (Fx_load_color_file):
19723 Read color file from absolute filename (bug#8250).
19725 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
19727 * makefile.w32-in: Update dependencies.
19729 2011-03-17 Eli Zaretskii <eliz@gnu.org>
19731 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

19737 * process.c (make_serial_process_unwind, send_process_trap):
19738 (sigchld_handler): Now static.
19740 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
19741 That way, the code declares only the vars that it needs.
19742 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
19743 * s/cygwin.h (PTY_ITERATION): Likewise.
19744 * s/darwin.h (PTY_ITERATION): Likewise.

19748 * process.c (allocate_pty): Don't declare stb unless it's needed.
19750 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
19751 (CONSTANTLIM): Remove; unused.
19752 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
19753 Define only if needed.
19755 * unexelf.c (unexec): Name an expression,
19756 to avoid gcc -Wbad-function-cast warning.
19757 Use a different way to cause a compilation error if anyone uses
19758 n rather than nn, a way that does not involve shadowing.
19759 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
19761 * deps.mk (unexalpha.o): Remove; unused.
19763 New file unexec.h, the (simple) interface for unexec (Bug#8267).
19764 * unexec.h: New file.
19765 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
19766 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
19767 Depend on unexec.h.
19768 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
19769 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
19770 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
19771 Change as necessary to match prototype in unexec.h.
19773 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid
19775 (back_comment, skip_chars): Mark vars as initialized.

19789 instead of using an uninitialized var.
19790 (font_sort_entities): Mark var as initialized.
19792 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
19794 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

19806 * floatfns.c (domain_error2): Define only if needed.
19807 (Ffrexp, Fldexp): Rename locals to avoid shadowing.
19809 * alloc.c (mark_backtrace): Move decl from here ...

19818 * callint.c (quotify_arg, quotify_args): Now static.
19819 (Fcall_interactively): Rename locals to avoid shadowing.
19820 Use const pointer when appropriate.
19822 * lisp.h (get_system_name, get_operating_system_release):

19826 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
19827 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
19828 some of which prompt warnings from gcc -Wbad-function-cast.
19829 (Fformat_time_string, Fencode_time, Finsert_char):
19830 (Ftranslate_region_internal, Fformat):
19831 Rename or remove local vars to avoid shadowing.
19832 (Ftranslate_region_internal): Mark var as initialized.
19834 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
19837 * lisp.h (eassert): Check that the argument compiles, even if
19838 ENABLE_CHECKING is not defined.
19840 * data.c (Findirect_variable): Name an expression, to avoid
19841 gcc -Wbad-function-cast warning.
19842 (default_value, arithcompare, arith_driver, arith_error): Now static.

19850 Rename locals to avoid shadowing.
19851 (mark_stack): Move local variables into the #ifdef region where
19853 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
19854 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
19856 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
19857 (GC_STRING_CHARS): Remove; not used.
19858 (Fmemory_limit): Cast sbrk's returned value to char *.
19860 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
19861 avoids undefined behavior in theory.
19863 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
19865 Use functions, not macros, for up- and down-casing (Bug#8254).
19866 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
19867 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
19868 to use the following functions instead of these macros.
19869 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
19870 EMACS_INT, since callers assume the returned value fits in int.
19871 (upcase1): Likewise, for UPCASE_TABLE.
19872 (uppercasep, lowercasep, upcase): New static inline functions.
19873 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
19874 the race-condition problem in the old DOWNCASE.
19876 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
19877 Rename locals to avoid shadowing.
19878 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
19879 (regex_compile, re_search_2, re_match_2_internal):
19880 Remove unused local vars.
19881 (FREE_VAR): Rewrite so as not to use empty "else",
19882 which gcc can warn about.
19883 (regex_compile, re_match_2_internal): Mark locals as initialized.
19884 (RETALLOC_IF): Define only if needed.
19885 (WORDCHAR_P): Likewise. This one is never needed, but is used
19886 only in a comment talking about a compiler bug, so put inside
19887 the #if 0 of that comment.
19888 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
19889 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
19892 * search.c (boyer_moore): Rename locals to avoid shadowing.
19893 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
19894 (PREV_CHAR_BOUNDARY): Likewise.

19904 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
19906 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
19907 Rename locals to avoid shadowing.
19908 (Fvertical_motion): Mark locals as initialized.
19910 * casefiddle.c (casify_object, casify_region): Now static.
19911 (casify_region): Mark local as initialized.
19913 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
19915 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
19916 New macros, so that the caller can use some names other than
19917 gcpro1, gcpro2, etc.
19918 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
19920 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
19921 argument, for consistency with GCPRO2_VAR, etc: it is now the
19922 prefix of the variable, not the variable itself. All uses
19924 * dired.c (directory_files_internal, file_name_completion):
19925 Rename locals to avoid shadowing.
19927 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
19928 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
19929 dired.c's scmp function, had undefined behavior.
19930 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
19931 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
19932 * buffer.h: ... to here, because these macros use current_buffer,
19933 and the new implementation with inline functions needs to have
19934 current_buffer in scope now, rather than later when the macros
19936 (downcase, upcase1): New static inline functions.
19937 (DOWNCASE, UPCASE1): Reimplement using these functions.
19938 This avoids undefined behavior in expressions like
19939 DOWNCASE (x) == DOWNCASE (y), which previously suffered
19940 from race conditions in accessing the global variables
19941 case_temp1 and case_temp2.
19942 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
19943 * lisp.h (case_temp1, case_temp2): Remove their decls.
19944 * character.h (ASCII_CHAR_P): Move from here ...
19945 * lisp.h: ... to here, so that the inline functions mentioned
19946 above can use them.
19948 * dired.c (directory_files_internal_unwind): Now static.
19950 * fileio.c (file_name_as_directory, directory_file_name):
19951 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
19953 (file_name_as_directory): Use const pointers when appropriate.
19954 (Fexpand_file_name): Likewise. In particular, newdir might
19955 point at constant storage, so make it a const pointer.
19956 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
19957 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
19959 (Fset_file_times, Finsert_file_contents, auto_save_error):
19960 Rename locals to avoid shadowing.
19962 * minibuf.c (choose_minibuf_frame_1): Now static.
19963 (Ftry_completion, Fall_completions): Rename or remove locals
19964 to avoid shadowing.
19966 * marker.c (bytepos_to_charpos): Remove; unused.
19968 * lisp.h (verify_bytepos, count_markers): New decls,
19969 so that gcc does not warn that these functions aren't declared.
19971 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
19972 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
19973 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
19974 (copy_text): Remove unused local var.
19976 * filelock.c (within_one_second): Now static.
19977 (lock_file_1): Rename local to avoid shadowing.
19979 * buffer.c (fix_overlays_before): Mark locals as initialized.
19980 (fix_start_end_in_overlays): Likewise. This function should be
19981 simplified by using pointers-to-pointers, but that's a different
19983 (switch_to_buffer_1): Now static.
19984 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
19985 (report_overlay_modification): Rename locals to avoid shadowing.
19987 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
19988 Fix pointer signedness issue.
19989 (sys_subshell): Mark local as volatile if checking for lint,
19990 to suppress a gcc -Wclobbered warning that does not seem to be right.
19991 (MAXPATHLEN): Define only if needed.
19993 * process.c (serial_open, serial_configure): Move decls from here ...
19994 * systty.h: ... to here, so that they can be checked.
19996 * fns.c (get_random, seed_random): Move extern decls from here ...
19997 * lisp.h: ... to here, so that they can be checked.
19999 * sysdep.c (reset_io): Now static.
20000 (wait_for_termination_signal): Remove; unused.
20002 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
20003 (copy_keymap_item, append_key, push_text_char_description):
