12 2012-12-03 Chong Yidong <cyd@gnu.org>
14 * fileio.c (Vauto_save_list_file_name): Doc fix.

34 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
36 Fix xpalloc confusion after memory is exhausted.
37 * alloc.c (xpalloc): Comment fix.
38 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
39 and signals an error, do not clear charset_table_size, as
40 charset_table is still valid.
41 * doprnt.c (evxprintf): Clear *BUF after freeing it.
43 Use execve to avoid need to munge environ (Bug#13054).
44 * callproc.c (Fcall_process):
45 * process.c (create_process):
46 Don't save and restore environ; no longer needed.
47 * callproc.c (child_setup):
48 Use execve, not execvp, to preserve environ.
50 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
52 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).

56 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
57 display for sliced images (Bug#10500).

63 * doc.c (Fdocumentation): Re-add handling of function-documentation,
64 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
66 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>

81 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
83 * callproc.c (Fcall_process): Fix vfork portability problems.
84 Do not assume that fd[0], count, filefd, and save_environ survive
85 vfork. Fix bug whereby wrong errno value could be reported for
86 pipe failure. Some minor cleanups, too, as follows. Move buf and
87 bufsize to the context where they're needed. Change new_argv to
88 be of type char **, as this is more convenient and avoids casts.
89 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
90 Now local constants, not macros.
92 2012-11-18 Kenichi Handa <handa@gnu.org>

142 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
143 between bpos_covered and bpos_max. This fixes cursor display when
144 several display strings follow each other.
146 * .gdbinit (pgx): If the glyph's object is a string, display the
147 pointer to string data, rather than the value of the string object
148 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
150 * indent.c (Fvertical_motion): If the starting position is covered
151 by a display string, return to one position before that, to avoid
152 overshooting it inside move_it_to. (Bug#12930)
154 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
156 * frame.h (struct frame): Remove display_preempted member

166 * xterm.h (struct x_output): Drop outdated #if 0 code.
167 Use bitfields for explicit_parent, asked_for_visible,
168 has_been_visible and net_wm_state_hidden_seen members.

173 of a literal "/". (Bug#12955)
174 (gl-stamp): Invoke fc.exe directly, not through cmd.
176 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
178 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
179 * dired.c: Assume HAVE_DIRENT_H.
180 (NAMLEN): Remove, replacing with ...
181 (dirent_namelen): New function. All uses changed. Use the GNU macro
182 _D_EXACT_NAMELEN if available, as it's faster than strlen.
183 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
184 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
185 * makefile.w32-in (DIR_H): Remove. All uses replaced with
187 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
188 * ndir.h: Rename to ../nt/inc/dirent.h.
189 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
190 Do not include <dirent.h>; no longer needed.
191 * w32.c: Include <dirent.h> rather than "ndir.h".
193 2012-11-23 Chong Yidong <cyd@gnu.org>
195 * xftfont.c (xftfont_open): Remove duplicate assignment.
197 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
199 * alloc.c (Fgarbage_collect): Unblock input after clearing
200 gc_in_progress to avoid note_mouse_highlight glitch with GC.
201 * frame.h (FRAME_MOUSE_UPDATE): New macro.
202 * msdos.c (IT_frame_up_to_date): Use it here...
203 * w32term.c (w32_frame_up_to_date): ...here...
204 * xterm.c (XTframe_up_to_date): ...and here...
205 * nsterm.m (ns_frame_up_to_date): ...but not here.
206 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
208 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):

215 simplify large 'if' statements.
216 (redisplay_internal): Generalize commonly used
217 'tail' and 'frame' local variables.
219 2012-11-22 Eli Zaretskii <eliz@gnu.org>
221 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
222 with Windows system header.
224 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
226 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
227 * alloc.c: Assume unistd.h exists.
228 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
229 * sysdep.c (get_current_dir_name): Assume getcwd exists.
230 (getwd) [USG]: Remove; no longer needed.
231 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.

233 * w32.h (getcwd): Remove decl.
235 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
237 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
238 Make it set selected_window as well.

243 * emacs.c (main): Set the G_SLICE environment variable for all
244 Cygwin builds, not just GTK builds. See
245 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
247 2012-11-21 Eli Zaretskii <eliz@gnu.org>
249 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
250 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
251 Define for the MSVC compiler.
253 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
255 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
256 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
257 dostounix_filename. Prevents crashes down the road, because
258 dostounix_filename assumes it gets a unibyte string. Reported by
259 Michel de Ruiter <michel@sentient.nl>, see
260 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
262 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>

275 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
277 * eval.c (interactive_p): Remove no-longer-used decl.
279 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>

286 (text_outside_line_unchanged_p, redisplay_window): Use it.
287 (redisplay_internal): Likewise. Fix indentation.
289 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
291 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
292 (syms_of_eval): Remove corresponding defsubr.
293 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
295 2012-11-19 Daniel Colascione <dancol@dancol.org>
297 * w32fns.c (Fx_file_dialog):
298 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
299 cygwin_convert_file_name*.

302 Rename cygwin_convert_path* to cygwin_convert_file_name*.
304 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
306 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
308 2012-11-18 Eli Zaretskii <eliz@gnu.org>
310 * w32select.c: Include w32common.h before w32term.h, so that
311 windows.h gets included before w32term.h uses some of its
314 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
316 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
318 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
320 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
322 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).

327 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
328 Needed following 2012-10-20 change. (Bug#12902)
330 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
332 * w32proc.c (waitpid): Remove unused label get_result.
334 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
336 * makefile.w32-in (SYSWAIT_H): New macro.
337 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
338 ($(BLD)/sysdep.$(O)): Update dependencies.
340 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
342 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
343 * callproc.c (relocate_fd): Assume F_DUPFD.
344 * emacs.c, term.c (O_RDWR): Remove.
345 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
346 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
347 * nsterm.m: Assume <fcntl.h> exists.
348 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
349 (create_pty, Fmake_network_process, server_accept_connection)
350 (wait_reading_process_output, init_process_emacs):
352 (wait_reading_process_output): Put in a special case for WINDOWSNT
353 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
354 It's not clear this is needed, but it's a more-conservative change.
355 (create_process): Assume FD_CLOEXEC.
356 (create_process, create_pty): Assume O_NOCTTY.
357 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
358 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
359 Omit if not DOS_NT, since F_GETFL is not defined there.
360 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
361 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
363 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
364 lack it, since gnulib guarantees this.
365 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
367 2012-11-17 Eli Zaretskii <eliz@gnu.org>
369 * w32.c (faccessat): Pretend that directories have the execute bit
370 set. Emacs expects that, e.g., in files.el:cd-absolute.
372 * w32proc.c (create_child): Don't clip the PID of the child
373 process to fit into an Emacs integer, as this is no longer a
375 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
376 reaping only the process specified by PID argument, if that is
377 positive. Use PID instead of dead_child to know which process to
378 reap. Wait for the child to die only if WNOHANG is not in
380 (sys_select): Don't set dead_child.
382 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
383 as it is no longer needed.
385 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
387 (record_child_status_change): Remove the setting of
388 record_at_most_one_child for the !WNOHANG case.
390 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
392 Fix problems in ns port found by static checking.
393 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
394 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
395 not to process group.
396 (ns_select): Use emacs_write, not write, as that's more robust
397 in the presence of signals.
398 (fd_handler:): Check for read errors.
400 2012-11-16 Glenn Morris <rgm@gnu.org>
402 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
404 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
406 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
408 2012-11-16 Eli Zaretskii <eliz@gnu.org>
410 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
411 use the same value of thread handle.
412 (start_timer_thread): If the timer thread exited (due to error),
413 clean up by closing the two handles it used. Duplicate the caller
414 thread's handle here, so it gets duplicated only once, when
415 launching the timer thread. Set priority of the timer thread, not
417 (getitimer): Don't duplicate the caller thread's handle here.
420 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
422 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
425 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
427 Remove no-longer-used pty_max_bytes variable.
428 * process.c (pty_max_bytes): Remove; unused.
429 (send_process): Do not set it.
431 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
433 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
436 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
438 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
439 This follows up on the 2012-09-29 patch that removed indirection
440 for the 'function' field. Reported by Sergey Vinokurov in
441 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
443 2012-11-14 Eli Zaretskii <eliz@gnu.org>
445 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
446 different name, as the MS runtime does not have such a function,
447 and probably never will.) All callers changed. Ignore DIRFD
448 value if PATH is an absolute file name, to match Posix spec
449 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
452 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
454 * xdisp.c (echo_area_display, redisplay_internal):
455 Omit redundant check whether frame_garbaged is set.
457 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
459 Use faccessat, not access, when checking file permissions (Bug#12632).
460 This fixes a bug that has been present in Emacs since its creation.
461 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
462 which must set some sort of record. (Torek's bug report was against
463 a predecessor of GNU Emacs, but GNU Emacs happened to have the
464 same common flaw.) See Torek's Usenet posting
465 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
466 Posted: Fri Apr 8 14:18:56 1983.

481 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
482 * fileio.c (check_existing, check_executable, check_writable)
484 Use symbolic names instead of integers for the flags, as they're
486 (check_writable): New arg AMODE. All uses changed.
487 Set errno on failure.
488 (Ffile_readable_p): Use faccessat, not stat + open + close.
489 (Ffile_writable_p): No need to call check_existing + check_writable.
490 Just call check_writable and then look at errno. This saves a syscall.
491 dir should never be nil; replace an unnecessary runtime check
492 with an eassert. When checking the parent directory of a nonexistent
493 file, check that the directory is searchable as well as writable, as
494 we can't create files in unsearchable directories.
495 (file_directory_p): New function, which uses 'stat' on most platforms
496 but faccessat with D_OK (for efficiency) if WINDOWSNT.
497 (Ffile_directory_p, Fset_file_times): Use it.
498 (file_accessible_directory_p): New function, which uses a single
499 syscall for efficiency.
500 (Ffile_accessible_directory_p): Use it.
501 * xrdb.c (file_p): Use file_directory_p.
502 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
503 * lread.c (openp): When opening a file, use fstat rather than
504 stat, as that avoids a permissions race. When not opening a file,
505 use file_directory_p rather than stat.
506 (dir_warning): First arg is now a usage string, not a format.
507 Use errno. All uses changed.
508 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
509 that merely introduced a race.
510 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
511 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
512 and similarly for the other O_* flags.
513 * w32.c (sys_faccessat): Rename from sys_access and switch to
514 faccessat's API. All uses changed.
515 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
516 (magic_db): Rename from magic_file_p.
517 (magic_db, search_magic_path): Return an XrmDatabase rather than a
518 char *, so that we don't have to test for file existence
519 separately from opening the file for reading. This removes a race
520 fixes a permission-checking problem, and simplifies the code.
522 (file_p): Remove; no longer needed.
524 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
526 Omit glyphs initialization at startup.

534 2012-11-13 Eli Zaretskii <eliz@gnu.org>
536 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
537 passed to pint2str and pint2hrstr to be at most the size of the
538 frame's decode_mode_spec_buffer. This avoids crashes with very
539 large values of FIELD_WIDTH argument to decode_mode_spec.
542 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
544 Fix a race with verify-visited-file-modtime (Bug#12863).
545 Since at least 1991 Emacs has ignored an mtime difference of no
546 more than one second, but my guess is that this was to work around
547 file system bugs that were fixed long ago. Since the race is
548 causing problems now, let's remove that code.
549 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
550 whose time stamp is off by no more than a second. Insist that the
551 file time stamps match exactly.
553 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
555 * frame.h (struct frame): Convert external_tool_bar member to
556 1-bit unsigned bitfield.
557 * termhooks.h (struct terminal): Remove mouse_moved member since
558 all users are long dead. Adjust comment on mouse_position_hook.
560 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
562 Simplify by using FOR_EACH_FRAME here and there.
563 * frame.c (next_frame, prev_frame, other_visible_frames)
564 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
565 * w32term.c (x_window_to_scroll_bar): Likewise.
566 * window.c (window_list): Likewise.
567 * xdisp.c (x_consider_frame_title): Likewise.
568 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.

570 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
571 * xmenu.c (menubar_id_to_frame): Likewise.
572 * xselect.c (frame_for_x_selection): Likewise.
573 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
574 (x_window_to_menu_bar): Likewise.
575 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
577 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
579 * data.c (Qdefalias_fset_function): Now static.
581 Another tweak to vectorlike_header change.
582 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
583 Remove, and replace all uses with ...
584 (next_in_free_list, set_next_in_free_list):
585 New functions, which respect C's aliasing rules better.
587 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
589 * window.c (list4i): Rename from 'quad'. All uses changed.
590 Needed because <sys/types.h> defines 'quad' on Solaris 10.
592 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
594 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
595 warning about mixing declarations and code in ISO C90.
597 2012-11-10 Martin Rudalics <rudalics@gmx.at>
599 * window.c (Fsplit_window_internal): Set combination limit of
600 new parent window to t iff Vwindow_combination_limit is t;
601 fixing a regression introduced with the change from 2012-09-22.
602 (Fset_window_combination_limit): Fix doc-string.
604 2012-11-10 Eli Zaretskii <eliz@gnu.org>
606 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
607 amount when the scroll margins are too large. When scrolling
608 backwards in the buffer, give up if cannot reach point or the
609 scroll margin within a reasonable number of screen lines.
610 Fixes point position in window under scroll-up/down-aggressively when
611 point is positioned many lines beyond the window top/bottom.
614 * ralloc.c (relinquish): If real_morecore fails to return memory
615 to the system, don't crash; instead, leave the last heap
616 unchanged and return. (Bug#12774)
618 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
620 * lisp.h (AUTOLOADP): New macro.
621 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
622 * data.c (Ffset): Remove special ad-advice-info handling.
623 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
625 (Finteractive_form): Simplify.
626 (Fquo): Don't insist on having at least 2 arguments.
627 (Qdefalias_fset_function): New var.
629 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
631 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
633 * nsfont.m (Qcondensed, Qexpanded): New variables.
634 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
635 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
637 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
639 Fix recently introduced crash on MS-Windows (Bug#12839).

641 (SCROLL_BAR_VEC_SIZE): Remove.
642 * w32term.c (x_scroll_bar_create): Use VECSIZE.
644 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
646 Tweak last vectorlike_header change.
647 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
648 vectorlike object on the free list. This is introduced to avoid
649 some (but not all) pointer casting and aliasing problems, see
650 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
651 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
653 (xvectype, xvecsize): Use them to examine Lisp_Object values.
655 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
657 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
658 been removed, so remove them here also.
660 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
662 * doc.c (Fdocumentation): Handle new property
663 dynamic-docstring-function to replace the old ad-advice-info.
665 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
667 * fns.c (Qeql, hashtest_eq): Now static.
669 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>

680 * lisp.h (sxhash_combine): New inline function, with the contents
681 of the old SXHASH_COMBINE.
682 * profiler.c (hashfn_profiler): Use it, instead of having a
683 special hash function containing a comparison that always yields 1.
685 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
687 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
688 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
689 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
692 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
694 * image.c (xpm_make_color_table_h): Fix compiler error because
695 make_hash_table changed.
697 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
699 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
701 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
703 Use ad-hoc comparison function for the profiler's hash-tables.
704 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.

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

732 known key modifiers. (Bug#12806)
734 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
736 Shrink struct vectorlike_header to the only size field.
737 * lisp.h (enum pvec_type): Avoid explicit enum member values.

760 (allocate_vector_from_block): Simplify.
761 (PSEUDOVECTOR_NBYTES): Replace with...

779 (xvecsize): New command.
781 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
783 * keyboard.c (event_to_kboard): Do not dereference
784 frame_or_window field of SELECTION_REQUEST_EVENT
785 and SELECTION_CLEAR_EVENT events (Bug#12814).
786 * xterm.h (struct selection_input_event): Adjust comment.
788 2012-11-07 Eli Zaretskii <eliz@gnu.org>
790 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
791 such as Scroll Lock, if the respective keys are treated as
792 function keys, not as modifiers. This avoids destroying non-ASCII
793 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
795 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
797 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
799 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
801 Restore some duplicate definitions (Bug#12814).
802 This undoes part of the 2012-11-03 changes. Some people build
803 with plain -g rather than with -g3, and they need the duplicate
804 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
805 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
806 Define as macros, as well as as enums or as constants.
808 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
810 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
811 to keypad keys (Bug#12816).
813 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
815 Minor adjustments of recently-changed frame functions.
816 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
817 known to be a frame (we're in the FRAMEP branch).
818 * lisp.h (Qframep): Remove decl. frame.h declares this.
819 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
820 since they're meant for Lisp fixnum values.
822 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
824 * window.c (Fwindow_combination_limit): Revert to the only
825 required argument and adjust docstring as suggested in
826 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
827 by Martin Rudalics <rudalics@gmx.at>.
829 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>

870 (Fwindow_line_height): Use it.
871 (Fwindow_fringes): Use list3.
872 (Fwindow_scroll_bars): Use list4.
873 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
874 (Fwindow_combination_limit): Allow zero number of arguments.
876 2012-11-05 Eli Zaretskii <eliz@gnu.org>
878 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
880 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
881 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
882 file descriptor 2 for standard error. (Bug#12805)
884 2012-11-05 Chong Yidong <cyd@gnu.org>
886 * process.c (wait_reading_process_output): Revert previous change.
888 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
890 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
891 This removes code that has been obsolete since around 1990.
892 * callproc.c (Fcall_process):
894 * process.c (create_process):
895 * term.c (dissociate_if_controlling_tty):
896 Assume setsid exists.
897 * callproc.c (child_setup): Assume setpgid exists and behaves as
898 per POSIX.1-1988 or later.
899 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
900 * emacs.c (shut_down_emacs):
901 * sysdep.c (sys_suspend, init_foreground_group):
902 Assume getpgrp behaves as per POSIX.1-1998 or later.
903 * msdos.c (setpgrp): Remove.
904 (tcgetpgrp, setpgid, setsid): New functions.
905 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.

913 Do not assume that __fpending's result fits in int.
915 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
917 Remove EMACS_OUTQSIZE+sleep hack.
918 * dispnew.c (update_frame_1): Remove hack for terminals slower
919 than 2400 bps, which throttled Emacs by having it sleep.
920 This code hasn't worked since at least 2007, when the multi-tty stuff
921 was added, and anyway those old terminals are long dead.
922 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
923 without the dispnew.c change, as dispnew.c doesn't include systty.h.
925 Fix data-loss with --version (Bug#9574).
926 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
927 as we can't assume that emacs_strerror is initialized, and strerror
929 (main): Invoke atexit earlier, to catch earlier instances of
930 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
932 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
934 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
935 (keyDown): Remap keypad keys to X11 virtual key codes.
937 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
939 Fix data-loss with --batch (Bug#9574).
940 * emacs.c: Include <close-stream.h>.
941 (close_output_streams): New function.
942 (main): Pass it to atexit, so that Emacs closes stdout and stderr
943 and handles errors appropriately.
944 (Fkill_emacs): Don't worry about flushing, as close_output_stream
947 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
948 The symptom is a diagnostic "GLib-WARNING **: In call to
949 g_spawn_sync(), exit status of a child process was requested but
950 SIGCHLD action was set to SIG_IGN and ECHILD was received by
951 waitpid(), so exit status can't be returned." The diagnostic
952 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
953 The real bug is a race condition between Emacs and glib: Emacs
954 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
955 so that glib can't find it. Work around the bug by invoking
956 waitpid only on subprocesses that Emacs itself creates.
957 * process.c (create_process, record_child_status_change):
958 Don't use special value -1 in pid field, as the caller now must
959 know the pid rather than having the callee infer it.
960 The inference was sometimes incorrect anyway, due to another race.
961 (create_process): Set new 'alive' member if child is created.
962 (process_status_retrieved): New function.
963 (record_child_status_change): Use it.
964 Accept negative 1st argument, which means to wait for the
965 processes that Emacs already knows about. Move special-case code
966 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
967 processes that have already been waited for, by testing and
968 clearing new 'alive' member.
969 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
970 now does this internally.
971 (handle_child_signal): Let record_child_status_change do all
972 the work, since we do not want to reap all exited child processes,
973 only the child processes that Emacs itself created.
974 * process.h (Lisp_Process): New boolean member 'alive'.
976 Omit duplicate definitions no longer needed with gcc -g3.
977 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
978 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
979 Define only as macros. There's no longer any need to also define
980 these symbols as enums or as constants, since we now assume
981 gcc -g3 when debugging.
983 2012-11-03 Eli Zaretskii <eliz@gnu.org>
985 * lisp.mk: Adjust comments to the fact that term/internal is now
986 loaded from loadup.el.
988 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
989 (msdos_fatal_signal): New function.
990 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
993 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
994 for GCC versions before 4.
995 (emacs_raise): Define to call msdos_fatal_signal.
997 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
998 iterator when starting in the middle of a display or overlay
1001 2012-11-03 Chong Yidong <cyd@gnu.org>
1003 * process.c (wait_reading_process_output): Clean up the last
1006 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
1008 * process.c (wait_reading_process_output): Avoid a race condition
1009 with SIGIO delivery (Bug#11536).
1011 2012-11-03 Chong Yidong <cyd@gnu.org>
1013 * buffer.c (cursor_type): Untabify docstring.
1015 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1017 * frame.h (struct frame): Drop can_have_scroll_bars member
1018 which is meaningless for a long time. Adjust comments.
1019 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
1020 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
1022 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1024 * window.c (decode_next_window_args): Update window arg after
1025 calling decode_live_window and so fix crash reported at
1026 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
1027 by Juanma Barranquero <lekktu@gmail.com>.
1028 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
1029 * font.c (Ffont_at): Likewise.
1031 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
1033 * widget.c (resize_cb): New function.
1034 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
1035 (EmacsFrameResize): Check if all is up to date before changing frame
1038 2012-11-02 Eli Zaretskii <eliz@gnu.org>
1040 Implement backtrace output for fatal errors on MS-Windows.
1041 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
1042 (BACKTRACE_LIMIT_MAX): New macro.
1043 (w32_backtrace): New function.
1044 (emacs_abort): Use w32_backtrace when the user chooses not to
1045 attach a debugger. Update the text of the abort dialog.
1047 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1049 Window-related stuff cleanup here and there.
1050 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
1051 Use decode_any_window.
1052 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
1053 * xdisp.c (Fformat_mode_line): Likewise.
1054 * font.c (Ffont_at): Use decode_live_window.
1055 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
1056 * window.c (decode_next_window_args): Likewise.
1057 (decode_any_window): Remove static.
1058 * window.h (decode_any_window): Add prototype.
1059 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
1060 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
1063 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1065 Remove pad from struct input_event.
1066 * termhooks.h (struct input_event): Remove padding field.
1068 * keyboard.c (event_to_kboard): Simplify because frame_or_window
1069 member is never cons for a long time. Adjust comment.
1070 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
1071 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
1072 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
1073 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
1075 2012-11-01 Eli Zaretskii <eliz@gnu.org>
1077 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
1079 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
1081 Fix crash when using Emacs as commit editor for git (Bug#12697).
1082 * callproc.c (setpgrp): Remove macro, as we now use setpgid
1083 and it is configured in conf_post.h.
1084 (Fcall_process): Don't invoke both setsid and setpgid; the former
1085 is enough, if it exists.
1086 * callproc.c (Fcall_process, child_setup):
1087 * process.c (create_process): Use setpgid.
1088 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
1090 * dispnew.c (init_display): Initialize the foreground group
1091 if we are running a tty display.
1092 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
1093 * lisp.h (init_foreground_group): New decl.
1094 * sysdep.c (inherited_pgroup): New static var.
1095 (init_foreground_group, tcsetpgrp_without_stopping)
1096 (narrow_foreground_group, widen_foreground_group): New functions.
1097 (init_sys_modes): Narrow foreground group.
1098 (reset_sys_modes): Widen foreground group.
1100 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
1102 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
1104 2012-10-31 Martin Rudalics <rudalics@gmx.at>
1106 * minibuf.c (read_minibuf): Restore current buffer since
1107 choose_minibuf_frame calling Fset_frame_selected_window may
1108 change it (Bug#12766).
1110 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
1112 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
1114 2012-10-30 Kenichi Handa <handa@gnu.org>
1116 * font.c (Ffont_at): If WINDOW is specified and it is not
1117 displaying the current buffer, signal an error.
1119 2012-10-29 Daniel Colascione <dancol@dancol.org>
1121 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
1122 In preparation for fixing bug#12739, move these functions from
1125 * coding.h, coding.c: ... to here, and compile them only when
1126 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
1127 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
1129 2012-10-28 Eli Zaretskii <eliz@gnu.org>
1131 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
1132 (timer_loop, getitimer, setitimer): Use it instead of
1133 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
1135 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
1138 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
1140 * nsterm.m (NO_APPDEFINED_DATA): New define.
1141 (last_appdefined_event_data): New variable
1142 (last_appdefined_event): Remove.
1143 (ns_select): Initialize t from last_appdefined_event_data instead
1144 of [last_appdefined_event data1].
1145 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
1146 remove last_appdefined_event (Bug#12698).
1148 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
1150 * frame.c (x_set_font): Catch internal error.
1152 2012-10-27 Eli Zaretskii <eliz@gnu.org>
1154 Avoid overflow in w32 implementation of interval timers.
1155 When possible, for ITIMER_PROF count only times the main thread
1157 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
1158 'volatile ULONGLONG' types. All the other data which was
1159 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
1160 (GetThreadTimes_Proc): New typedef.
1161 (w32_get_timer_time): New function, returns a suitable time value
1163 (timer_loop): Enter critical section when accessing ULONGLONG
1164 values of the itimer_data struct, as these accesses are no longer
1165 atomic. Call 'w32_get_timer_time' instead of 'clock'.
1166 Remove unused variable.
1167 (init_timers): Initialize s_pfn_Get_Thread_Times.
1168 (start_timer_thread): Don't assign itimer->caller_thread here.
1169 (getitimer): Assign itimer->caller_thread here.
1170 (setitimer): Always call getitimer to get the value of ticks_now.
1171 (sys_spawnve): Avoid compiler warning about format mismatch.
1173 2012-10-26 Eli Zaretskii <eliz@gnu.org>
1175 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
1176 mouse movement events if the menu bar is active. This avoids
1177 producing a busy "hour-glass" cursor by Windows if the mouse
1178 pointer is positioned over a tooltip shown for some menu item.
1180 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
1182 Don't assume process IDs fit in int.
1183 * emacs.c (shut_down_emacs) [!DOS_NT]:
1184 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
1185 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
1186 Use pid_t, not int, to store process IDs, as 'int'
1187 is not wide enough on a few platforms (e.g., AIX and IRIX).
1189 2012-10-23 Kenichi Handa <handa@gnu.org>
1191 The following change is to make face-font-rescale-alist work
1192 correctly for non-ASCII fonts.
1194 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
1195 (font_open_for_lface): Handle Vface_font_rescale_alist.
1197 2012-10-23 Chong Yidong <cyd@gnu.org>
1199 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
1201 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>

1210 2012-10-21 Glenn Morris <rgm@gnu.org>
1212 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
1214 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
1216 Port to OpenBSD 5.1.
1217 * frame.c (Fmouse_position, Fmouse_pixel_position):
1218 * xdisp.c (produce_stretch_glyph):
1219 Declare local vars only when they're needed.
1220 This is clearer and avoids a warning on OpenBSD about unused vars.
1221 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
1222 This is safer, and avoids OpenBSD warnings about unused vars.
1223 * keyboard.c (record_menu_key): Remove unnecessary decl.
1224 (poll_timer): Define only if POLL_FOR_INPUT is defined.
1225 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
1226 as our definition clashes with OpenBSD's.
1227 * xfaces.c (load_face_colors, check_lface_attrs)
1228 (get_lface_attributes_no_remap, get_lface_attributes)
1229 (lface_fully_specified_p, x_supports_face_attributes_p)
1230 (tty_supports_face_attributes_p, face_fontset, realize_face)
1231 (realize_x_face, realize_tty_face):
1232 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
1233 merely Lisp_Object *. This is more informative and avoids
1234 a warning on OpenBSD about accessing beyond an object's size.
1236 2012-10-20 Chong Yidong <cyd@gnu.org>
1238 * lread.c (Fload): Doc fix (Bug#12592).
1240 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
1242 * font.c (Ffont_at): Fix previous change.
1244 2012-10-19 Eli Zaretskii <eliz@gnu.org>
1246 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
1247 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
1250 * alloc.c (NSTATICS): Decrease to 0x800.
1252 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>
1254 * fns.c (Fnreverse): Include the problem element when signalling an
1257 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
1259 * nsterm.m (ns_select): Check writefds before call to
1260 FD_ISSET (Bug#12668).
1262 2012-10-18 Daniel Colascione <dancol@dancol.org>
1264 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
1265 (staticpro): If we run out of staticpro slots, die with an
1266 informative error instead of just calling emacs_abort.
1268 2012-10-18 Martin Rudalics <rudalics@gmx.at>
1270 Fix two flaws reported by Dmitry Antipov.
1271 * window.c (Ftemp_output_buffer_show): Remove.

1292 (set_process_dir, sys_spawnve, register_child, sys_sleep, getwd)
1293 (sys_link): Add prototypes.
1295 * w32.c: Include w32select.h.
1296 (sys_access, e_malloc, sys_select): Add prototypes.
1297 (emacs_gnutls_pull): 'timeout' is now EMACS_TIME, not struct timeval.
1299 * vm-limit.c [WINDOWSNT]: Include w32heap.h.
1301 * unexw32.c: Include lisp.h and w32.h.
1303 * term.c [WINDOWSNT]: Include w32term.h.

1311 * cygw32.c (Fcygwin_convert_path_to_windows)
1312 (Fcygwin_convert_path_from_windows): Use EQ to compare 2
1313 Lisp_Object values. (Bug#12661)
1315 * w32fns.c (w32_msg_pump): Use XIL instead of casting an integer
1316 to Lisp_Object. (Bug#12661)

1331 * buffer.h (BUFFER_CHECK_INDIRECTION): New macro.
1332 * buffer.c (compact_buffer, set_buffer_internal_1): Use it.
1334 2012-10-16 Dmitry Antipov <dmantipov@yandex.ru>

1337 * print.c (print_interval): Define as static to match prototype.
1338 * indent.c (disptab_matches_widthtab, recompute_width_table):

1362 enabled by undefining the symbol "interface", which the platform
1363 headers define to something incompatible.
1365 2012-10-14 Daniel Colascione <dancol@dancol.org>
1367 * image.c (init_tiff_functions, init_imagemagick_functions)
1368 (init_svg_functions): Fix cygw32 build break by using these
1369 functions only when WINDOWSNT _and_ HAVE_NTGUI.

1386 * fileio.c: Formatting fixes.
1388 2012-10-13 Paul Eggert <eggert@cs.ucla.edu>
1390 Fix some stat-related races.
1391 * fileio.c (Fwrite_region): Avoid race condition if a file is
1392 removed or renamed by some other process immediately after Emacs
1393 writes it but before Emacs stats it. Do not assume that stat (or
1395 * image.c (slurp_file): Resolve the file name with fopen + fstat
1396 rather than stat + fopen.

1424 * fileio.c (check_existing): New function.
1425 (make_temp_name, Ffile_exists_p, Ffile_writable_p): Call it
1426 instead of calling 'stat', when what's needed is to check whether
1427 a file exists. This avoids expensive system calls on MS-Windows.
1430 * w32.c (init_environment): Call 'check_existing' instead of 'stat'.
1432 * lread.c (openp) [WINDOWSNT]: Call 'access' instead of 'stat' to
1433 determine whether a file exists and is not a directory.
1435 * lisp.h (check_existing): Add prototype.
1437 2012-10-12 Jan Djärv <jan.h.d@swipnet.se>
1439 * nsfont.m (nsfont_open): Remove font cache, it is not GC correct.

1469 Use bool for booleans.
1470 * lread.c (safe_to_load_version): Rename from safe_to_load_p,
1471 as it's not a predicate. All uses changed. Omit unnecessary
1474 2012-10-11 Dmitry Antipov <dmantipov@yandex.ru>
1476 * editfns.c (save_excursion_save): Use nil if mark points to nowhere.
1477 (save_excursion_restore): Do not restore mark if it was not saved.
1479 2012-10-11 Paul Eggert <eggert@cs.ucla.edu>
1481 * marker.c (cached_modiff): EMACS_INT, not int.
1483 * w32select.c (waiting_for_input): Declare by including "keyboard.h"
1484 instead of having a wrong decl.
1485 * nsmenu.m (waiting_for_input): Remove wrong decl.
1487 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>

1522 (detect_input_pending_run_timers):
1523 * process.c (wait_reading_process_output):
1524 Use unsigned for counter where wraparound-on-overflow is desired,
1525 since unsigned is guaranteed to have that behavior and signed is not.
1526 (read_char): Use ptrdiff_t for string length.
1527 (get_input_pending): Remove first argument, since it was always
1528 the same pointer-to-int (now pointer-to-boolean) &input_pending,
1529 and behave as if it had that value. Return new value of
1530 input_pending. All callers changed.
1531 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
1532 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
1534 * keymap.c (push_key_description): Omit last arg, which was always 1.
1535 All callers changed.
1537 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.
1539 2012-10-10 Juanma Barranquero <lekktu@gmail.com>

1555 Don't include termopts.h.
1557 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
1559 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
1561 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
1563 * commands.h (immediate_quit): Remove duplicate decl.
1565 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
1567 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles
1569 (nsfont_open): Remove setting of Vfonts_in_cache.
1570 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
1572 2012-10-09 Eli Zaretskii <eliz@gnu.org>
1574 * w32fns.c (w32_last_error): Change the return value to DWORD, to
1575 match what GetLastError returns. Explain why the function is
1578 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
1579 'is_tooltip_frame', to avoid confusion with its global namesake.
1581 2012-10-08 Daniel Colascione <dancol@dancol.org>
1583 * xdisp.c (start_hourglass): Call w32_note_current_window when
1584 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
1585 build that caused Emacs to display the hourglass cursor forever.
1587 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
1588 which is broken under remote desktop, calculate the number of
1589 colors available for a display based on the display's number of
1590 planes and number of bits per pixel per plane. (bug#10397).
1592 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
1594 * nsfont.m (Vfonts_in_cache): New variable.
1595 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
1596 are used. Add cached fonts to Vfonts_in_cache.
1597 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
1599 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
1601 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
1603 (FONT_H): Define after FRAME_H.
1604 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
1605 Update dependencies.
1607 * w32term.c: Remove leftover declaration of keyboard_codepage.
1609 2012-10-08 Eli Zaretskii <eliz@gnu.org>
1611 * makefile.w32-in (FONT_H): Add $(FRAME_H).
1612 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
1613 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
1614 (GLOBAL_SOURCES): Add cygw32.c.

1617 ($(BLD)/w32console.$(O)):
1618 ($(BLD)/w32fns.$(O)):
1619 ($(BLD)/w32heap.$(O)):
1620 ($(BLD)/w32menu.$(O)):
1621 ($(BLD)/w32proc.$(O)): Add w32common.h.
1623 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
1625 (x_to_w32_color): Don't modify the argument, modify a copy instead.
1627 2012-10-08 Daniel Colascione <dancol@dancol.org>
1629 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
1630 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
1631 accidental message numbering hole. Change other messages to
1634 * w32select.h (HAVE_W32SELECT): Remove.
1636 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
1637 w32common.h instead of w32heap.h.
1639 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
1640 (get_allocation_unit, get_processor_type, get_w32_major_version)
1641 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
1642 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
1643 (OS_NT, os_subtype, cache_system_info): Move declarations to
1646 * w32heap.c: Include w32common.h.
1647 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
1648 (w32_minor_version, w32_build_number, w32_subtype):
1649 Remove duplicate definitions.
1651 * w32fns.c: Include w32common.h; include w32heap.h only in
1654 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
1655 Use `report_file_error' instead of `error' in order to better
1656 inform users of what went wrong. Increase NTGUI_UNICODE file
1657 dialog box file name length to 32k, the maximum allowed by the NT
1660 * w32common.h: New file.
1661 (ROUND_UP, ROUND_DOWN, get_page_size)
1662 (get_allocation_unit, get_processor_type, get_w32_major_version)
1663 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
1664 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
1665 (OS_NT, os_subtype, cache_system_info): Move here.
1667 * unexw32.c, unexcw.c: Include w32common.h.
1669 * emacs.c (main): Use (defined (WINDOWSNT) || defined
1670 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
1671 to call syms_of_w32select.
1673 * cygw32.h: Remove obsolete EXFUN declarations.
1675 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
1677 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
1678 of w32inevt.o from SOME_MACHINE_OBJECTS.
1680 2012-10-08 Daniel Colascione <dancol@dancol.org>
1682 * image.c: Permanent fix for JPEG compilation issue --- limit
1683 jpeglib `boolean' redefinition to Cygwin builds.
1685 2012-10-08 Eli Zaretskii <eliz@gnu.org>
1687 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
1689 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
1692 2012-10-08 Daniel Colascione <dancol@dancol.org>
1694 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
1695 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
1696 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
1697 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
1698 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
1699 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
1700 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
1701 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
1702 now a supported configuration.
1704 * Makefile.in: consolidate image variables into LIBIMAGE; add
1705 W32_OBJ and W32_LIBS. Compile new files.
1708 (_DebPrint) declare tracing facility for W32 debugging. We need
1709 to unify tracing later.
1711 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
1712 unconditional use of W32 Unicode functions. Cygwin runs only on
1713 100% Unicode operating systems.
1715 * cygw32.c: New file. Define Cygwin-specific facilities.
1716 (Fcygwin_convert_path_to_windows)
1717 (Fcygwin_convert_path_from_windows): New user functions for
1718 accessing Cygwin path-munging routines.
1720 * cygw32.h: New file.
1721 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
1722 UTF-16LE strings temporarily inside non-Lisp-visible string
1725 (w32_strerror): Just what it says on the tin.
1727 * emacs.c: Make the NS fork-then-exec code for daemon-launching
1728 also run for Cygwin; both systems have the same problem with using
1729 GUI facilities in a forked child. Also call syms_of_cygw32,
1730 syms_of_w32select in correct places.
1732 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
1733 needs fork-then-exec for daemon launching.
1735 * font.h: Include frame.h.
1737 * image.c: Use the image library cache machinery only when we're
1738 compiling for native WINDOWSNT; Cygwin can use shared libraries
1739 like any other Unixlike system.
1741 * keyboard.c: Clarify a comment regarding the input loop.
1743 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
1744 functions directly instead of trying to detect at runtime that our
1745 host operating system supports them. We make this change for two
1746 reasons: Cygwin lacks support for the multibyte character
1747 conversion functions used by the legacy menu code, and Cygwin
1748 never needs to rely on non-Unicode APIs.
1750 * unexw32.c (hinst): Declare extern.
1752 * w32.c: Change header order;
1753 (w32_strerror): Move to w32fns.c because we need it for
1754 non-WINDOWSNT builds.
1756 * w32.h: Add #error macro to make sure we don't include w32.h for
1757 Cygwin builds. Remove w32select declarations.
1759 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
1760 w32fns.c. w32console.c is WINDOWSNT-only.
1762 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
1763 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
1765 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
1766 (w32_major_version, w32_minor_version, w32_build_number)
1767 (os_subtype, sound_type): Define here
1768 (w32_defined_color): Make color parameter const for consistency
1769 with other _defined_color functions.
1770 (w32_createwindow): Unconditionally call w32_init_class instead of
1771 doing so only when hprevinst is non-NULL. Plumbing hprevinst
1772 through the code is complex and unnecessary because class
1773 registration is practically free.
1774 (w32_name_of_message): New EMACSDEBUG-only function.
1775 (Fset_message_beep): Move here
1776 (Fx_open_connection): Require that the display name for Windows be
1777 "w32" for consistency, emacsclient disambiguation, and maybe, one
1778 day, multi-window-system support.
1779 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
1780 Cygwin files for W32 GUI facilities, since these clearly don't
1781 expect Cygwin names.
1782 (_DebPrint): Define.
1783 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
1784 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
1785 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
1786 (w32_last_error): Remove.
1788 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
1790 * w32heap.c (syspage_mask): Declare here.
1791 (cache_system_info): Remove.
1793 * w32inevt.c (faked_key): Define globally, not statically.
1794 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
1795 (w32_console_toggle_lock_key): Move to w32fns.c.
1797 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
1799 * w32proc.c (_DebPrint): Move to w32fns.c.
1800 * w32select.c: Include string.h, stdio.h for Cygwin.
1801 * w32select.h: New File.
1803 * w32term.c: Include io.h for non-CYGWIN builds; needed for
1805 (w32_message_fd): New variable. Under Cygwin, holds the file
1806 descriptor the system used to tell us about pending thread
1809 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
1810 that prevented compilation under non-WINDOWSNT systems.
1812 (w32_initialize): Open /dev/windows and assign it to
1813 w32_message_fd. Provide w32 feature.
1815 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
1816 (WM_EMACS_INPUT_READY): add.
1817 (prepend_msg, w32_message_fd): Declare globally.
1820 (keyboard_handle): Use only when WINDOWSNT.
1821 (notify_msg_ready): New function. Posts a message to the main
1822 thread's message queue under CYGWIN, which wakes up the main
1823 thread from select(2) by making the /dev/windows file descriptor
1824 ready. Under WINDOWSNT, it sets an event the same way the old
1827 (post, prepend_msg): Actually call notify_msg_ready instead of
1828 setting the input event directly.
1830 2012-10-07 Eli Zaretskii <eliz@gnu.org>
1832 * ralloc.c (relinquish): If a heap is ready to be relinquished,
1833 but it still has blocs in it, don't return it to the system,
1834 instead of aborting. (Bug#12402)
1836 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
1838 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
1840 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
1841 MAC_OS_X_VERSION_10_6.
1842 (syms_of_nsterm): Remove comment about Panther and above for
1844 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
1845 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
1846 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
1848 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
1849 MAC_OS_X_VERSION_10_4.
1851 * nsmenu.m (fillWithWidgetValue:): Remove code for <
1852 MAC_OS_X_VERSION_10_2.
1854 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
1856 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
1857 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
1859 * nsterm.m (ns_in_resize): Remove (Bug#12479).
1860 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
1861 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
1862 Remove ns_in_resize check.
1863 (ns_clear_frame_area): Remove resize handle code.
1865 * nsfns.m (ns_in_resize): Remove.
1866 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
1867 Remove ns_in_resize check.
1869 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
1871 Improve sys_siglist detection.
1872 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
1873 defined as a macro, as is done in Solaris.
1874 (sys_siglist_entries): New macro.
1875 (save_strsignal): Use it.
1876 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
1877 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
1879 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
1881 * nsfns.m (Fx_create_frame): Call x_default_parameter with
1882 fullscreen/Fullscreen.
1884 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
1885 tobar_height is new.
1887 * nsterm.m (x_make_frame_visible): Check for fullscreen.
1888 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
1889 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
1890 (windowDidResize:): Check for correct window if old style fullscreen.

1904 2012-10-05 Eli Zaretskii <eliz@gnu.org>
1906 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
1908 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
1909 that time stamps of directories could also be changed.
1910 Don't request the too broad GENERIC_WRITE, only the more restrictive
1911 FILE_WRITE_ATTRIBUTES access rights.
1913 * fileio.c (Fset_file_times): Special-case ignoring errors for
1914 directories only on MSDOS, not on MS-Windows.
1916 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
1918 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
1920 2012-10-04 Eli Zaretskii <eliz@gnu.org>
1922 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
1923 see whether CreateFile failed.
1925 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
1927 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
1928 to avoid similar races.
1929 * keyboard.c (pending_signals): Now bool, not int.
1931 Port timers to OpenBSD, plus check for timer failures.
1932 OpenBSD problem reported by Han Boetes.
1933 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
1935 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
1936 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
1937 like OpenBSD, which has timer_settime but does not declare it.
1938 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
1939 whether to use itimerspec-related primitives. All uses of
1940 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
1942 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
1944 * profiler.c (handle_profiler_signal): Fix a malloc race
1945 that caused Emacs to hang on Fedora 17 when profiling Lisp.
1947 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
1949 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
1951 2012-10-02 Eli Zaretskii <eliz@gnu.org>
1953 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
1954 consistent with the change in return value of 'safe_strsignal'.
1956 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
1958 Prefer plain 'static' to 'static inline' (Bug#12541).

1960 (bidi_set_sor_type, bidi_push_embedding_level)
1961 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

1966 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
1967 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
1968 Now 'static', not 'static inline'.
1970 Count overruns when profiling; change units to ns.
1971 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
1972 Give extra weight to samples after overruns, to attempt to count
1973 the time more accurately.
1974 (setup_cpu_timer): Change sampling interval units from ms to ns, since
1975 the underlying primitives nominally do ns.
1976 (Fprofiler_cpu_start): Document the change. Mention that
1977 the sampling intervals are only approximate.
1979 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
1981 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
1983 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
1984 case for the special 0 coding-system.
1986 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
1987 (Fmake_overlay): Remove redundant tests.
1988 (fix_start_end_in_overlays): Remove redundant recentering.
1990 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
1992 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
1993 Update dependencies.
1995 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
1997 Fix a malloc race condition involving strsignal.
1998 A signal can arrive in the middle of a malloc, and Emacs's signal
1999 handler can invoke strsignal, which can invoke malloc, which is
2000 not portable. This race condition bug makes Emacs hang on GNU/Linux.
2001 Fix it by altering the signal handler so that it does not invoke
2003 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
2004 * process.c (status_message): Use const pointer, in case strsignal
2005 is #defined to safe_strsignal.
2006 * sysdep.c (sys_siglist, init_signals): Always define and
2007 initialize a substitute sys_siglist if the system does not define
2008 one, even if HAVE_STRSIGNAL.
2009 (safe_strsignal): Rename from strsignal. Always define,
2010 using sys_siglist. Return a const pointer.
2011 * syssignal.h (safe_strsignal): New decl.
2012 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
2014 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2016 * w32proc.c (timer_loop): Fix code that waits for timer
2017 expiration, to avoid high CPU usage.
2019 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
2021 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
2022 (sweep_weak_table): Remove redundant prototypes.
2024 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
2026 * emacs.c: Move the inclusion of TERM_HEADER after including
2027 windows.h on WINDOWSNT. This avoids compilation problems with
2030 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2032 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
2033 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
2034 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
2035 as the previous version used 'void *'.
2037 * ralloc.c (ROUNDUP): Fix last change.
2038 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
2041 * w32proc.c <disable_itimers>: New static flag.
2042 (init_timers): Initialize it to zero, after creating the critical
2043 sections used by the timer threads.
2044 (term_timers): Set to 1 before deleting the critical sections.
2045 (getitimer, setitimer): If disable_itimers is non-zero, return an
2046 error indication without doing anything. Reported by Fabrice
2047 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
2048 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
2050 [!HAVE_SETITIMER]: Behave as the previous version that didn't
2053 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
2054 term_ntproc after all the other bookkeeping, to get timers working
2055 as long as possible.
2057 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2059 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
2060 Suggested by Juri Linkov in
2061 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
2063 Prefer plain 'static' to 'static inline' (Bug#12541).
2064 With static functions, modern compilers inline pretty well by
2065 themselves; advice from programmers often hurts as much as it helps.
2066 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
2067 this change shrinks the text size of the Emacs executable by 1.1%
2068 without affecting CPU significantly in my benchmark.
2069 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

2151 Revert the FOLLOW-SYMLINKS change for file-attributes.
2152 Doing it right would require several changes to Tramp, and there's
2153 not enough time to get that tested before the freeze today.
2154 * dired.c (directory_files_internal, Ffile_attributes):
2157 * frame.c (x_report_frame_params): Port better to wider ints.
2158 Do not assume that EMACS_UINT is the same width as uprintmax_t,

2338 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
2340 * syssignal.h (PROFILER_CPU_SUPPORT): Don't define if PROFILING.
2341 Suggested by Eli Zaretskii in
2342 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
2344 2012-09-30 Eli Zaretskii <eliz@gnu.org>
2346 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
2347 HAVE_TIMER_SETTIME is defined.
2349 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
2351 Profiler improvements: more-accurate timers, overflow checks.
2352 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
2353 signal.h, setjmp.h. Include systime.h instead.
2354 (saturated_add): New function.
2355 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.
2356 (record_backtrace, handle_profiler_signal): Saturate on fixnum overflow.
2357 (profiler_timer, profiler_timer_ok) [HAVE_TIMER_SETTIME]:
2359 (enum profiler_cpu_running): New enum.
2360 (profiler_cpu_running): Now of that enum type, not bool.
2361 All uses changed to store the new value.
2362 (handle_profiler_signal): Rename from sigprof_handler_1,
2363 for consistency with other handlers. Do not check whether
2364 cpu_log is a hash-table if garbage collecting, since it
2365 doesn't matter in that case.
2366 (deliver_profiler_signal): Rename from sigprof_handler,
2367 for consistency with other handlers.
2368 (setup_cpu_timer): New function, with much of what used to be in
2369 Fprofiler_cpu_start. Check for out-of-range argument.
2370 Prefer timer_settime if available, and prefer
2371 thread cputime clocks, then process cputime clocks, then
2372 monotonic clocks, to the old realtime clock. Use make_timeval
2373 to round more-correctly when falling back to setitimer.
2374 (Fprofiler_cpu_start): Use it.
2375 (Fprofiler_cpu_stop): Prefer timer_settime if available.
2376 Don't assume that passing NULL as the 2nd argument of setitimer
2377 is the same as passing a pointer to all-zero storage.
2378 Ignore SIGPROF afterwards.
2379 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
2380 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
2381 non-fatal signal handlers. Ignore SIGPROF on startup.
2382 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
2383 in profiler.c, since sysdep.c now uses it.
2385 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
2386 Suggested by Eli Zaretskii in
2387 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

2400 (Fbacktrace_frame): Adjust accordingly.
2402 2012-09-28 Glenn Morris <rgm@gnu.org>
2404 * eval.c (Frun_hook_with_args, Frun_hook_with_args_until_success)
2405 (Frun_hook_with_args_until_failure): Doc fixes.

2409 * xdisp.c (syms_of_xdisp) <Qredisplay_internal>: Rename from
2410 Qautomatic_redisplay and change the symbol name. All users changed.

2423 * Makefile.in (LIB_TIMER_TIME): New macro.
2425 * atimer.c (alarm_timer, alarm_timer_ok, set_alarm, init_atimer):

2437 2012-09-26 Paul Eggert <eggert@cs.ucla.edu>
2439 * character.h (MAYBE_UNIFY_CHAR): Remove.
2440 * charset.c, charset.h (maybe_unify_char): Now static.
2441 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
2442 Since this stuff is now private to charset.c, there's no need for
2443 a public macro and no need to inline by hand.
2445 2012-09-26 Tomohiro Matsuyama <tomo@cx4a.org>
2446 Stefan Monnier <monnier@iro.umontreal.ca>
2447 Juanma Barranquero <lekktu@gmail.com>

2476 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
2478 Prefer POSIX timers if available.
2479 They avoid a race if the timer is too close to the current time.
2480 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
2481 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
2482 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
2484 2012-09-25 Eli Zaretskii <eliz@gnu.org>
2486 * coding.c (CHAR_STRING_ADVANCE_NO_UNIFY): Make it an alias of
2487 CHAR_STRING_ADVANCE.
2488 (STRING_CHAR_ADVANCE_NO_UNIFY): Make it an alias of
2489 STRING_CHAR_ADVANCE.

2505 (globals_of_w32) <Vlibrary_cache>: Do not initialize.
2507 * w32.h (Vlibrary_cache): Do not declare.
2509 2012-09-25 Eli Zaretskii <eliz@gnu.org>
2511 * w32proc.c (sys_signal): Handle all signals defined by the
2512 MS-Windows runtime, not just SIGCHLD. Actually install the signal
2513 handlers for signals supported by Windows. Don't override
2514 term_ntproc as the handler for SIGABRT.
2515 (sigaction): Rewrite to call sys_signal instead of duplicating its
2517 (sys_kill): Improve commentary.
2519 * w32.c (term_ntproc): Accept (and ignore) one argument, for
2520 consistency with a signature of a signal handler. All callers
2522 (init_ntproc): Accept an argument DUMPING. If dumping, don't
2523 install term_ntproc as a signal handler for SIGABRT, as that
2524 should be done by the dumped Emacs.
2526 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
2528 * w32select.c (term_w32select): Protect against repeated
2529 invocation by setting clipboard_owner to NULL after calling
2532 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
2533 and term_ntproc to their modified signatures.
2535 * character.c (char_string, string_char): Remove calls to
2536 MAYBE_UNIFY_CHAR. See the discussion starting at
2537 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
2540 2012-09-25 Chong Yidong <cyd@gnu.org>

2544 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
2546 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
2547 when encountering an unknown bytecode.
2549 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
2551 image.c, indent.c: Use bool for booleans.
2552 * dispextern.h (struct image_type): Members valid_p, load, init
2553 now return bool, not int. All uses changed.
2554 * image.c: Omit unnecessary static decls.
2555 (x_create_bitmap_mask, x_build_heuristic_mask):

2593 Move pid_t related decls out of lisp.h.
2594 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
2595 (interruptible_wait_for_termination):
2596 Move these decls from lisp.h to syswait.h, since they use pid_t.
2597 Needed on FreeBSD; see Herbert J. Skuhra in
2598 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.

2647 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
2648 fatal_error_backtrace.
2650 * w32proc.c (sys_kill): Undo last change: don't do anything when
2651 invoked to deliver SIGABRT to our own process. This is now
2652 handled by emacs_raise.
2654 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
2656 * w32term.c (w32_read_socket): Remove leftover reference to
2657 interrupt_input_pending.
2659 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
2661 Do not use SA_NODEFER.
2662 Problem reported by Dani Moncayo in
2663 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
2665 * sysdep.c (emacs_abort): Do not reset signal handler.
2666 * emacs.c (terminate_due_to_signal): Reset signal handler here.
2667 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
2668 wanted even on POSIXish hosts, and it doesn't work on Windows.
2670 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
2672 * xterm.c (x_term_init): Call fixup_locale before and after calling
2673 gtk_init (Bug#12392).
2675 2012-09-23 Chong Yidong <cyd@gnu.org>
2677 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
2678 Vdynamic_library_alist.
2680 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
2681 (Fgnutls_available_p): Caller changed.
2683 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
2684 (Flibxml_parse_xml_region): Likewise.
2686 * dispextern.h (struct image_type): Remove arg from init function.
2688 * image.c (Finit_image_library, lookup_image_type)
2689 (define_image_type): Remove now-unneeded second arg.
2690 (init_xpm_functions, init_png_functions, init_jpeg_functions)
2691 (init_tiff_functions, init_gif_functions, init_svg_functions):
2692 Arglist and w32_delayed_load calling convention changed.
2693 (gs_type): Remove init_gs_functions; there is no such function.
2694 (valid_image_p, make_image): Fix caller to lookup_image_type.
2696 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
2698 Simplify and avoid signal-handling races (Bug#12471).
2700 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
2701 Avoid recursive loop if there's a fatal error in the function itself.
2702 * atimer.c (pending_atimers):
2703 * blockinput.h: Don't include "atimer.h"; no longer needed.
2704 (interrupt_input_pending): Remove. All uses removed.
2705 pending_signals now counts both atimers and ordinary interrupts.
2706 This is less racy than having three separate pending-signal flags.
2707 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
2709 Rename from their upper-case counterparts BLOCK_INPUT,
2710 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
2711 INPUT_BLOCKED_P, and turn into functions. All uses changed.
2712 This makes it easier to access volatile variables more accurately.
2713 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
2714 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
2715 that's more reliable if the code is buggy and sets
2716 interrupt_input_blocked to a negative value. All uses changed.
2717 * atimer.c (deliver_alarm_signal):
2718 Remove. No need to deliver this to the parent; any thread can
2719 handle this signal now. All uses replaced by underlying handler.
2720 * atimer.c (turn_on_atimers):
2721 * dispnew.c (handle_window_change_signal):
2722 * emacs.c (handle_danger_signal):
2723 * keyboard.c (kbd_buffer_get_event):
2724 Don't reestablish signal handler; not needed with sigaction.
2725 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
2727 Rework to avoid unnecessary accesses to volatile variables.
2728 (UNBLOCK_INPUT_TO): Now a function.
2729 (totally_unblock_input, unblock_input): New decls.
2730 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
2731 (init_data): Remove. Necessary stuff now done in init_signal.
2732 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
2733 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
2734 (fatal_error_code): Remove; no longer needed.
2735 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
2736 it doesn't always backtrace. All uses changed. No need to reset
2737 signal to default, since sigaction and/or die does that for us now.
2738 Use emacs_raise (FOO), not kill (getpid (), FOO).
2739 (main): Check more-accurately whether we're dumping.
2740 Move fatal-error setup to sysdep.c
2741 * floatfns.c: Do not include "syssignal.h"; no longer needed.
2742 * gtkutil.c (xg_get_file_name, xg_get_font):
2743 Remove no-longer-needed signal-mask manipulation.
2744 * keyboard.c, process.c (POLL_FOR_INPUT):
2745 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
2746 * keyboard.c (read_avail_input): Remove.
2747 All uses replaced by gobble_input.
2748 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
2749 (kbd_buffer_store_event_hold, gobble_input):
2750 (record_asynch_buffer_change) [USABLE_SIGIO]:
2751 (store_user_signal_events):
2752 No need to mess with signal mask.
2753 (gobble_input): If blocking input and there are terminals, simply
2754 set pending_signals to 1 and return. All hooks changed to not
2755 worry about whether input is blocked.
2756 (process_pending_signals): Clear pending_signals before processing
2757 them, in case a signal comes in while we're processing.
2758 By convention callers now test pending_signals before calling us.
2759 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
2760 New functions, to support changes to blockinput.h.
2761 (handle_input_available_signal): Now extern.
2762 (reinvoke_input_signal): Remove. All uses replaced by
2764 (quit_count): Now volatile, since a signal handler uses it.
2765 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
2766 All callers changed. Block SIGINT only if not already blocked.
2767 Clear sigmask reliably, even if Fsignal returns, which it can.
2768 Omit unnecessary accesses to volatile var.
2769 (quit_throw_to_read_char): No need to restore sigmask.
2770 * keyboard.c (gobble_input, handle_user_signal):
2771 * process.c (wait_reading_process_output):
2772 Call signal-handling code rather than killing ourselves.
2773 * lisp.h: Include <float.h>, for...
2774 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
2775 (pending_signals): Now volatile.
2776 (syms_of_data): Now const if IEEE floating point.
2777 (handle_input_available_signal) [USABLE_SIGIO]:
2778 (terminate_due_to_signal, record_child_status_change): New decls.
2779 * process.c (create_process): Avoid disaster if memory is exhausted
2780 while we're processing a vfork, by tightening the critical section
2782 (send_process_frame, process_sent_to, handle_pipe_signal)
2783 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
2785 (send_process): No need for setjmp/longjmp any more, since the
2786 SIGPIPE stuff is now gone. Instead, report an error if errno
2788 (record_child_status_change): Now extern. PID and W are now args.
2789 Return void, not bool. All callers changed.
2790 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
2791 Remove. All uses removed. This bug should be fixed now in a
2793 (wait_for_termination_1): Use waitpid rather than sigsuspend,
2794 and record the child status change directly. This avoids the
2795 need to futz with the signal mask.
2796 (process_fatal_action): Move here from emacs.c.
2797 (emacs_sigaction_flags): New function, containing
2798 much of what used to be in emacs_sigaction_init.
2799 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
2800 caught by emacs, to make races less likely.
2801 (deliver_process_signal): Rename from handle_on_main_thread.
2803 (BACKTRACE_LIMIT_MAX): Now at top level.
2804 (thread_backtrace_buffer, threadback_backtrace_pointers):
2806 (deliver_thread_signal, deliver_fatal_thread_signal):
2807 New functions, for more-accurate delivery of thread-specific signals.
2808 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
2809 (deliver_arith_signal): Handle in this thread, not
2810 in the main thread, since it's triggered by this thread.
2811 (maybe_fatal_sig): New function.
2812 (init_signals): New arg DUMPING so that we can be more accurate
2813 about whether we're dumping. Caller changed.
2814 Treat thread-specific signals differently from process-general signals.
2815 Block all signals while handling fatal error; that's safer.
2816 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
2818 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
2819 Ignore SIGPIPE unless batch.
2820 (emacs_backtrace): Output backtrace for the appropriate thread,
2821 which is not necessarily the main thread.
2822 * syssignal.h: Include <stdbool.h>.
2823 (emacs_raise): New macro.
2824 * xterm.c (x_connection_signal): Remove; no longer needed
2825 now that we use sigaction.
2826 (x_connection_closed): No need to mess with sigmask now.
2827 (x_initialize): No need to reset SIGPIPE handler here, since
2828 init_signals does this for us now.
2830 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
2832 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
2833 background rect may be larger (Bug#12245).
2835 2012-09-23 Chong Yidong <cyd@gnu.org>
2837 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
2839 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
2841 * .gdbinit: Just stop at fatal_error_backtrace.
2842 See Stefan Monnier's request in
2843 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
2844 Remove no-longer-used query of system type.
2846 2012-09-22 Chong Yidong <cyd@gnu.org>
2848 * search.c (Freplace_match): Doc fix (Bug#12325).
2850 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
2852 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
2853 (Fline_end_position): Doc fix.
2855 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
2857 2012-09-22 Chong Yidong <cyd@gnu.org>
2859 * dispextern.h (struct image_type): Add new slot, storing a type
2860 initialization function.
2862 * image.c (define_image_type): Call the image initializer function
2863 if it is defined. Arguments and return value changed.
2864 (valid_image_p, make_image): Callers changed.
2865 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
2866 (gif_type, imagemagick_type, svg_type, gs_type):
2867 Add initialization functions.
2868 (Finit_image_library): Call lookup_image_type.
2869 (CHECK_LIB_AVAILABLE): Macro deleted.
2870 (lookup_image_type): Call define_image_type here, rather than via
2871 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
2872 (syms_of_image): Move define_image_type calls for xbm_type and
2873 pbm_type to lookup_image_type.
2875 2012-09-22 Eli Zaretskii <eliz@gnu.org>
2877 * keyboard.c (timer_check_2): Move calculation of 'timers' and
2878 'idle_timers' from here ...
2879 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
2880 lists, to avoid infloops when the timer does something stupid,
2881 like reinvoke itself with the same or smaller time-out.
2884 2012-09-22 Martin Rudalics <rudalics@gmx.at>
2886 * window.c (Fsplit_window_internal): Handle only Qt value of
2887 Vwindow_combination_limit separately.
2888 (Qtemp_buffer_resize): New symbol.
2889 (Vwindow_combination_limit): New default value.
2892 2012-09-22 Eli Zaretskii <eliz@gnu.org>
2894 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
2895 the new overlay string. (Bug#10159)
2897 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
2899 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
2900 or that fprintf is async-signal-safe. POSIX doesn't require
2903 2012-09-22 Chong Yidong <cyd@gnu.org>
2905 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
2908 2012-09-22 Kenichi Handa <handa@gnu.org>
2910 * composite.c (composition_reseat_it): Handle the case that a
2911 grapheme cluster is not covered by a single font (Bug#12352).
2913 2012-09-21 Chong Yidong <cyd@gnu.org>
2915 * image.c (define_image_type): Avoid adding duplicate types to
2916 image_types (Bug#12463). Suggested by Jörg Walter.
2918 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2920 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
2921 (print_load_command_name): Add case LC_DATA_IN_CODE.
2922 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
2924 2012-09-21 Glenn Morris <rgm@gnu.org>
2926 * eval.c (Frun_hook_with_args_until_success)
2927 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
2929 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
2931 * fileio.c (Ffile_selinux_context): Only call freecon when
2932 lgetfilecon succeeded.
2933 (Fset_file_selinux_context): Likewise. (Bug#12444)
2935 2012-09-21 Eli Zaretskii <eliz@gnu.org>
2937 * xdisp.c (try_window_reusing_current_matrix): Under bidi
2938 reordering, locate the cursor by calling set_cursor_from_row; if
2939 that fails, clear the desired glyph matrix before returning a
2940 failure indication to the caller. Fixes leaving garbled display
2941 when fast scrolling with a down-key. (Bug#12403)
2942 (compute_stop_pos_backwards): Fix a typo that caused crashes while
2943 scrolling through multibyte text.
2945 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
2947 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
2948 calling mark_vectorlike since that's the one that marks the window.
2949 (mark_discard_killed_buffers): Mark the final cdr.
2950 * window.h (struct window): Move prev/next_buffers to the
2951 non-standard fields.
2952 * window.c (make_window): Initialize prev/next_buffers manually.
2954 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
2956 Omit unused arg EXPECTED from socket hooks.
2957 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
2958 * nsterm.m (ns_term_init):
2959 * termhooks.h (struct terminal.read_socket_hook):
2960 * w32inevt.c (w32_console_read_socket):
2961 * w32term.c (w32_read_socket):
2962 * xterm.c (XTread_socket):
2963 Omit unused arg EXPECTED. All callers changed.
2964 (store_user_signal_events): Return void, not int, since callers no
2965 longer care about the return value. All uses changed.
2967 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
2969 * w32gui.h (XParseGeometry): Do not declare.
2971 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
2973 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
2974 Ignore 'expected'. See Eli Zaretskii in
2975 <http://bugs.gnu.org/12471#8> (last line).
2977 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
2978 (XParseGeometry): Now static. Substitute extremal values for
2979 values that are out of range.
2981 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
2983 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
2985 * nsfns.m (XParseGeometry): Remove.
2986 (Fx_create_frame): Call x_set_offset to correctly interpret
2987 top_pos in geometry.
2989 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
2990 (Fx_parse_geometry): If there is a space in string, call
2991 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
2993 2012-09-17 Eli Zaretskii <eliz@gnu.org>
2995 * search.c (scan_buffer): Use character positions in calls to
2996 region_cache_forward and region_cache_backward, not byte
2997 positions. (Bug#12196)
2999 * w32term.c (w32_read_socket): Set pending_signals to 1, like
3000 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
3002 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
3003 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
3004 emacs_blocked_malloc, now deleted.
3006 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
3008 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
3009 The workaround was for improving performance on Solaris 2.4, but
3010 is getting in the way now. Emacs will still work if someone is
3011 still running Solaris 2.4 in a museum somewhere; Sun dropped
3012 support for Solaris 2.4 in 2003.
3013 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
3014 * process.c (create_process) [HAVE_WORKING_VFORK]:
3015 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
3016 since Emacs no longer uses vfork on that platform.
3018 2012-09-17 Glenn Morris <rgm@gnu.org>
3020 * emacs.c: Use COPYRIGHT.
3022 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
3024 Remove configure's --without-sync-input option (Bug#12450).
3025 When auditing signal-handling in preparation for cleaning it up,
3026 I found that SYNC_INPUT has race conditions and would be a real
3027 pain to fix. Since it's an undocumented and deprecated
3028 configure-time option, now seems like a good time to remove it.
3029 Also see <http://bugs.gnu.org/11080#16>.
3030 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
3031 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
3032 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3033 (malloc_hysteresis):
3034 (check_depth) [XMALLOC_OVERRUN_CHECK]:
3035 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
3036 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
3037 (dont_register_blocks, bytes_used_when_reconsidered)
3038 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
3039 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
3040 [!SYSTEM_MALLOC && !SYNC_INPUT]:
3041 Remove. All uses removed.
3042 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
3043 implementation, one that depends on whether the new macro
3044 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
3046 * atimer.c (run_timers, handle_alarm_signal):
3047 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
3048 (handle_async_input, process_pending_signals)
3049 (handle_input_available_signal, init_keyboard):
3050 * nsterm.m (ns_read_socket):
3051 * process.c (wait_reading_process_output):
3052 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
3053 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
3055 * xterm.c (XTread_socket):
3057 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
3058 * eval.c (handling_signal): Remove. All uses removed.
3059 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
3060 All uses replaced with the SYNC_INPUT version.
3061 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
3063 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3066 * font.c (Ffont_shape_gstring): Remove unused local.
3068 2012-09-16 Glenn Morris <rgm@gnu.org>
3070 * Makefile.in (clean): No longer run nextstep's clean.
3072 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
3074 (ns-app): Move here from ns.mk, and simplify.
3075 (clean): Simplify nextstep entry.
3076 * ns.mk: Remove file.
3078 2012-09-17 Kenichi Handa <handa@gnu.org>
3080 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
3081 not covert the last few charactes.
3083 2012-09-16 Kenichi Handa <handa@gnu.org>
3085 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
3086 here, but just check the validity of glyphs in the glyph-string.
3088 2012-09-16 Martin Rudalics <rudalics@gmx.at>
3090 * window.c (Fwindow_parameter, Fset_window_parameter):
3091 Accept any window as argument (Bug#12452).
3093 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
3095 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
3096 to ns_term_init to avoid memory leak.
3098 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
3099 explicit retain/release.
3100 (ns_term_init): Only allow one display. Initialize outerpool and
3103 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3105 Port _setjmp fix to POSIXish hosts as well as Microsoft.
3106 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
3107 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
3108 the Microsoft problem in a different way, by altering ../nt/config.nt.
3110 2012-09-15 Eli Zaretskii <eliz@gnu.org>
3125 * w16select.c: Remove inclusion of setjmp.h, as it is now included
3126 by lisp.h. This completes removal of setjmp.h inclusion
3127 erroneously announced in the previous commit. (Bug#12446)
3129 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
3132 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
3133 not defined as a macro. The latter happens on MS-Windows.
3136 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3138 Port better to POSIX hosts lacking _setjmp (Bug#12446).
3139 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
3140 Some instances of '#include <setjmp.h>' removed, if the
3141 only reason for the instance was because "lisp.h" was included.
3142 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
3143 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
3144 and _longjmp with the new symbols. Emacs already uses _setjmp if
3145 available, so this change affects only POSIXish hosts that have
3146 sigsetjmp but not _setjmp, such as some versions of Solaris and
3147 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
3148 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
3149 (png_load_body) [HAVE_PNG]:
3150 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
3151 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
3152 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
3153 since PNG requires jmp_buf. This is the only exception to the
3154 general rule that we now use sys_setjmp and sys_longjmp.
3155 This exception is OK since this code does not change the signal
3156 mask or longjmp out of a signal handler.
3158 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
3160 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3161 Include "syssignal.h", for 'main_thread'.
3163 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
3165 Avoid out-of-range marker position (Bug#12426).
3166 * insdel.c (replace_range, replace_range_2):
3167 Adjust markers before overlays, as suggested by comments.
3168 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
3169 Remove redundant check before calling offset_intervals.
3171 2012-09-14 Martin Rudalics <rudalics@gmx.at>
3173 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
3174 current buffer (Bug#12387).
3176 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
3178 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
3180 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3182 Use a more backwards-compatible timer format (Bug#12430).
3183 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
3184 vector element, not from the 4th, since PSECS is now at the end.
3185 (Fcurrent_idle_time): Doc fix.
3187 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
3189 Function to mark objects and remove killed buffers at once.
3190 * alloc.c (discard_killed_buffers): Rename to ...
3191 (mark_discard_killed buffers) ... new name. Add marking
3192 of remaining objects. Fix comment. Adjust users.
3193 (mark_object): Do not touch frame buffer lists here.
3194 * frame.c (delete_frame): Reset frame buffer lists here.
3196 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3198 Better workaround for GNOME bug when --enable-gcc-warnings.
3199 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
3200 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
3201 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
3203 Simplify SIGIO usage (Bug#12408).
3204 The code that dealt with SIGIO was crufty and confusing, e.g., it
3205 played tricks like "#undef SIGIO" but these tricks were not used
3206 consistently. Simplify mostly by not #undeffing standard symbols,
3207 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
3208 or not as we please) rather than "defined SIGIO" (standard symbol
3209 that we probably shouldn't #undef).
3210 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
3211 Modules that need it can include it.
3212 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
3213 * dispextern.h (ignore_sigio): New decl.
3214 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
3215 unconditionally, since it's now a no-op if !USABLE_SIGIO.
3216 * emacs.c (shut_down_emacs):
3217 * keyboard.c (kbd_buffer_store_event_hold):
3218 Use ignore_sigio rather than invoking 'signal' directly.
3219 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
3221 (FIONREAD, SIGIO): Do not #undef.
3222 (tty_read_avail_input): Use #error rather than a syntax error.
3223 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
3224 for I_PIPE, used by SETUP_SLAVE_PTY.
3225 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
3226 * sysdep.c (croak): Remove; no longer needed. This bit of
3227 temporary code, with Fred N. Fish's comment that it's temporary,
3228 has been in Emacs since at least 1992!
3229 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
3230 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
3231 * syssignal.h (croak): Remove decl.
3232 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
3233 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
3234 now that we're termios-only.
3235 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
3236 * term.c (dissociate_if_controlling_tty): Use #error rather than
3239 Work around GCC and GNOME bugs when --enable-gcc-warnings.
3240 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
3241 to work around GNOME bug 683906.
3242 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
3243 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
3244 This works around GCC bug 54561.
3246 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
3248 More fixes for 'volatile' and setjmp/longjmp.
3249 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
3250 * image.c (struct png_load_context) [HAVE_PNG]: New type.
3251 (png_load_body) [HAVE_PNG]:
3252 (jpeg_load_body) [HAVE_JPEG]:
3253 New function, with most of the old parent function's body.
3254 (png_load) [HAVE_PNG]:
3255 (jpeg_load) [HAVE_JPEG]:
3256 Invoke the new function, to avoid longjmp munging our locals.
3257 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
3258 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
3259 longjmp is passed 2, as the C standard doesn't guarantee this.
3260 Instead, store the failure code into mgr->failure_code.
3262 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
3264 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
3265 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
3266 (syms_of_keyboard): Remove support for unread-command-char.
3268 2012-09-12 Eli Zaretskii <eliz@gnu.org>
3270 * w32proc.c (sys_kill): If PID is our process ID and the signal is
3271 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
3272 violation. (Bug#12426)
3274 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
3276 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
3278 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
3280 * eval.c: Add `inhibit-debugger'.
3281 (Qinhibit_debugger): New symbol.
3282 (call_debugger): Bind it instead of Qdebug_on_error.
3283 (maybe_call_debugger): Test Vinhibit_debugger.
3284 (syms_of_eval): Define inhibit-debugger.
3285 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
3286 (syms_of_xdisp): Remove inhibit-debug-on-message.
3288 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
3290 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
3291 If a nonvolatile local variable is written before a _longjmp to
3292 the frame containing the variable, and is read after the _longjmp,
3293 the value read is indeterminate. Some local variables of type
3294 'struct handler' and 'struct catchtag' are used in this way, so
3295 mark each of their slots as volatile if the slot can be set before
3296 _longjmp and read afterwards.
3297 * lisp.h (struct handler): var and chosen_clause are now volatile.
3298 (struct catchtag): val, next, and pdlcount are now volatile.
3300 * bidi.c (bidi_push_it, bidi_pop_it):
3301 * fns.c (copy_hash_table):
3302 * image.c (define_image_type):
3303 * keyboard.c (kbd_buffer_store_event_hold):
3304 * process.c (Fprocess_send_eof):
3305 * xfaces.c (x_create_gc) [HAVE_NS]:
3306 * xgselect.c (xg_select):
3307 Prefer assignment to memcpy when either will do.
3309 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
3310 Use pointer-to-a-pointer to simplify and avoid a NILP check each
3311 time an item is removed. No need to mark this function 'inline';
3312 the compiler knows better than we do.
3314 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
3316 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
3317 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
3318 to change_frame_size (Bug#12388).
3319 (windowDidResize:): Pass YES to updateFrameSize.
3321 * nsterm.h: Add delay parameter to updateFrameSize.
3323 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
3325 Discard killed buffers from deleted window and frame objects.
3326 This reduces an amount of references to killed buffers and
3327 helps GC to reclaim them faster.
3328 * alloc.c (discard_killed_buffers): New function.
3329 (mark_object): Use it for deleted windows and frames.
3330 (mark_object): If symbol's value is set up for a killed buffer
3331 or deleted frame, restore its global binding.
3332 * data.c (swap_in_global_binding): Add GC notice.
3333 (swap_in_symval_forwarding): Use convenient set_blv_where.
3334 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
3335 * window.h: ... to here.
3337 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
3339 Convenient macro to check whether the buffer is live.
3340 * buffer.h (BUFFER_LIVE_P): New macro.
3341 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
3342 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
3344 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3346 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
3347 composition cases (Bug#12364).
3349 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
3350 overhang of succeeding glyphs overlapping box cursor.
3352 * w32term.c (x_draw_glyph_string): Likewise.
3354 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
3356 Simplify, document, and port floating-point (Bug#12381).
3357 The porting part of this patch fixes bugs on non-IEEE platforms
3358 with frexp, ldexp, logb.
3359 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
3361 * floatfns.c: Simplify discussion of functions that Emacs doesn't
3362 support, by removing commented-out code and briefly listing the
3363 C89 functions excluded. The commented-out stuff was confusing
3364 maintenance, e.g., we thought we needed cbrt but it was commented out.
3365 (logb): Remove decl; no longer needed.
3366 (isfinite): New macro, if not already supplied.
3367 (isnan): Don't replace any existing macro.
3368 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
3369 are present on all C89 platforms.
3370 (Ffrexp): Do not special-case zero, as frexp does the right thing
3372 (Flogb): Do not use logb, as it doesn't have the desired meaning
3373 on hosts that use non-base-2 floating point. Instead, stick with
3374 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
3375 frexp, to avoid getting an unspecified result.
3377 * xdisp.c (Qinhibit_debug_on_message): Now static.
3379 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
3381 * nsterm.m (ns_update_begin): Set clip path to whole view by using
3382 NSBezierPath (Bug#12131).
3384 2012-09-10 Chong Yidong <cyd@gnu.org>
3386 * fns.c (Fdelq, Fdelete): Doc fix.
3388 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
3390 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
3391 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
3393 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
3395 * lisp.h (make_lisp_ptr): New macro to replace XSET.
3396 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
3399 2012-09-09 Eli Zaretskii <eliz@gnu.org>
3401 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
3402 left fringe if the window has a left margin. This avoids leaving
3403 traces of the cursor because its leftmost pixel is not drawn over.
3405 * dispnew.c (update_window_line): When the left margin area of a
3406 screen line is updated, set the redraw_fringe_bitmaps_p flag of
3407 that screen line. (Bug#12277)
3409 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
3411 Assume C89 or later for math functions (Bug#12381).
3412 This simplifies the code, and makes it a bit smaller and faster,
3413 and (most important) makes it easier to clean up signal handling
3414 since we can stop worring about floating-point exceptions in
3415 library code. That was a problem before C89, but the problem
3416 went away many years ago on all practical Emacs targets.
3417 * data.c, image.c, lread.c, print.c:
3418 Don't include <math.h>; no longer needed.
3419 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
3420 might be autoconfigured, as that never happens.
3422 * doprnt.c (DBL_MAX_10_EXP):
3423 * print.c (DBL_DIG):
3424 Remove. C89 or later always defines these.
3425 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
3426 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
3427 (arith_error, domain_error, domain_error2):
3428 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
3429 no longer needed -- we simply return what C returns. All uses removed.
3430 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
3432 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
3433 Remove. All uses expanded, as these macros are no longer used
3434 more than once and are now more trouble than they're worth.
3435 (Ftan): Use tan, not sin / cos.
3436 (Flogb): Assume C89 frexp.
3437 (fmod_float): Assume C89 fmod.
3438 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
3439 (init_floatfns): Remove. All uses removed.
3441 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3443 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
3444 compositeToPoint for OSX < 10.6 (Bug#12390).
3446 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
3448 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
3449 This produces more-accurate results.
3451 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3453 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
3454 changes (Bug#12088).
3456 2012-09-08 Chong Yidong <cyd@gnu.org>
3458 * syntax.c (Fstring_to_syntax): Doc fix.
3460 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3462 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
3463 in the internal border.
3464 (x_set_window_size): Remove static variables and their usage.
3465 (ns_redraw_scroll_bars): Fix NSTRACE arg.
3466 (ns_after_update_window_line, ns_draw_fringe_bitmap):
3467 Remove fringe/internal border adjustment (Bug#11052).
3468 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
3469 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
3470 (ns_fix_rect_ibw): Remove.
3471 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
3472 (ns_dumpglyphs_box_or_relief): Ditto.
3473 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
3475 (ns_dumpglyphs_image): Ditto.
3476 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
3478 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
3479 their usage. Add fringe_extended_p and its use as in other terms.
3480 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
3481 scroll bar was removed.
3482 (updateFrameSize): New function.
3483 (windowDidResize): Move code to updateFrameSize and call it.
3485 * nsterm.h (EmacsView): Add updateFrameSize.
3487 2012-09-07 Chong Yidong <cyd@gnu.org>
3489 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
3491 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
3493 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
3495 More signal-handler cleanup (Bug#12327).
3496 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
3497 Problem introduced when merging patches. Noted by Eli Zaretskii in
3498 <http://bugs.gnu.org/12327#67>.
3499 * floatfns.c: Comment fix.
3500 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
3501 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
3502 and anyway the declaration is harmless even if SIGDANGER is not defined.
3503 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
3504 defined BROKEN_FIONREAD). systty.h formerly did this, but other
3505 source files not surprisingly expected syssignal.h to define, or
3506 not define, SIGIO, and it's cleaner to do it that way, for consistency.
3507 Include <sys/ioctl.h>, for FIONREAD.
3508 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
3509 This eliminates a problem whereby other files mysteriously had
3510 to include "syssignal.h" before including "systty.h" if they
3511 wanted to use "#ifdef SIGIO".
3513 2012-09-07 Eli Zaretskii <eliz@gnu.org>
3515 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
3517 * w32.c (sigemptyset): Empty the set.
3518 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
3520 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
3522 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
3524 * alloc.c (mark_buffer): Revert unsafe marking optimization.
3525 (mark_object): Likewise for frame objects.
3527 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
3529 * syssignal.h (handle_on_main_thread): Always declare,
3530 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
3531 This ports to platforms without HAVE_PTHREAD.
3533 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
3535 Signal-handler cleanup (Bug#12327).
3536 Emacs's signal handlers were written in the old 4.2BSD style with
3537 sigblock and sigmask and so forth, and this led to some
3538 inefficiencies and confusion. Rewrite these to use
3539 pthread_sigmask etc. without copying signal sets around. Also,
3540 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
3541 'signal', and instead use functions that do not attempt to take
3542 over the system name space. This patch causes Emacs's text
3543 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
3544 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
3545 Do not include <signal.h> or "syssignal.h", as these
3546 modules do not use signals.
3547 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
3548 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
3549 Do not include <signal.h>, as "syssignal.h" does that for us now.
3550 * atimer.c (sigmask_atimers): New function.
3551 (block_atimers, unblock_atimers): New functions,
3552 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
3554 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
3555 no longer needed here.
3556 * emacs.c (main): Inspect existing signal handler with sigaction,
3557 so that there's no need to block and unblock SIGHUP.
3558 * sysdep.c (struct save_signal): New member 'action', replacing
3559 old member 'handler'.
3560 (save_signal_handlers, restore_signal_handlers):
3561 Use sigaction instead of 'signal' to save and restore.
3562 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
3563 New function. All users of 'signal' modified to use set_sighandler
3564 if they're writeonly, and to use sys_signal if they're read+write.
3565 (emacs_sigaction_init, forwarded_signal): New functions.
3566 (sys_signal): Remove. All uses replaced by calls to sigaction
3567 and emacs_sigaction_init, or by direct calls to 'signal'.
3568 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
3569 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
3570 all uses replaced by pthread_sigmask etc. calls.
3571 * syssignal.h: Include <signal.h>.
3572 (emacs_sigaction_init, forwarded_signal): New decls.
3573 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
3574 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
3575 (sigmask, sys_sigmask): Remove; no longer needed.
3576 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
3577 (sigblock, sigunblock, sigfree):
3578 (sigsetmask) [!defined sigsetmask]:
3579 Remove. All uses replaced by pthread_sigmask.
3580 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
3581 no longer need to be replaced, and its typical old uses
3582 are now done via emacs_sigaction_init and sigaction.
3583 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
3584 (sys_sigdel): Remove; unused.
3585 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
3587 2012-09-06 Eli Zaretskii <eliz@gnu.org>
3589 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
3590 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
3592 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
3594 Explicitly mark buffer_defaults and buffer_local_symbols.
3595 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
3596 mark_local_symbols here.
3597 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
3598 since special buffers aren't marked here any more.
3599 (allocate_buffer): Chain new buffer with all_buffers here...
3600 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
3602 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
3603 (syms_of_buffer): Remove staticpro of the above.
3604 (init_buffer_once): Set names for buffer_defaults and
3605 buffer_local_symbols.
3607 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
3609 Use bool for booleans in font-related modules.
3610 * font.c (font_intern_prop, font_style_to_value)
3611 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
3612 (generate_otf_features, font_check_otf_features, font_check_otf)
3613 (font_match_p, font_list_entities, font_at):
3614 * fontset.c (fontset_id_valid_p, reorder_font_vector
3615 (fontset_find_font, Fset_fontset_font)
3616 (face_suitable_for_char_p) [0]:
3617 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
3618 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
3619 (m17n_flt_initialized, ftfont_shape_by_flt):
3620 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
3621 * nsfont.m (nsfont_draw):
3622 * w32font.c (w32font_draw):
3623 * w32term.c (x_draw_glyphless_glyph_string_foreground):
3624 Use bool for booleans.
3625 * font.h: Adjust to above API changes.
3626 (struct font, struct font_driver, struct font_driver_list):
3627 Use bool for booleans.
3628 (struct font): Remove useless member encoding_type.
3630 * fontset.c, xftfont.c: Omit unnecessary static decls.
3632 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
3634 * alloc.c (mark_object): Revert window marking code
3635 since it's unsafe for the Fset_window_configuration.
3637 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
3639 Fix race conditions with signal handlers and errno (Bug#12327).
3640 Be more systematic about preserving errno whenever a signal
3641 handler returns, even if it's not in the main thread. Do this by
3642 renaming signal handlers to distinguish between signal delivery
3643 and signal handling. All uses changed.
3644 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
3645 * data.c (deliver_arith_signal): Rename from arith_error.
3646 * dispnew.c (deliver_window_change_signal): Rename from
3647 window_change_signal.
3648 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
3649 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
3650 * keyboard.c (deliver_input_available_signal): Rename from
3651 input_available_signal.
3652 (deliver_user_signal): Rename from handle_user_signal.
3653 (deliver_interrupt_signal): Rename from interrupt_signal.
3654 * process.c (deliver_pipe_signal): Rename from send_process_trap.
3655 (deliver_child_signal): Rename from sigchld_handler.
3656 * atimer.c (handle_alarm_signal):
3657 * data.c (handle_arith_signal):
3658 * dispnew.c (handle_window_change_signal):
3659 * emacs.c (handle_fatal_signal, handle_danger_signal):
3660 * keyboard.c (handle_input_available_signal):
3661 * keyboard.c (handle_user_signal, handle_interrupt_signal):
3662 * process.c (handle_pipe_signal, handle_child_signal):
3663 New functions, with the actual signal-handling code taken from the
3664 original respective signal handlers, sans the sporadic attempts to
3665 preserve errno, since that's now done by handle_on_main_thread.
3666 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
3667 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
3668 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3670 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3671 Move initialization of main_thread to sysdep.c's init_signals.
3672 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
3673 our usage, and simplifies the mainline code.
3674 (record_child_status_change): New static function, as a helper
3675 for handle_child_signal, and with most of the old child handler's
3677 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
3678 (handle_child_signal): Use the above.
3679 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3680 Moved here from emacs.c.
3681 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
3682 code moved here from emacs.c's main function.
3683 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
3684 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
3685 This lets callers save and restore errno properly.
3687 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3689 Remove redundant or unused things here and there.
3690 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
3691 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
3692 * editfns.c (Fcompare_buffer_substrings): Likewise.
3693 * frame.h (struct terminal, struct font_driver_list):
3694 Remove redundant declarations.
3695 * window.h (Qleft, Qright): Likewise.
3697 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3699 Do not mark objects from deleted buffers, windows and frames.
3700 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
3701 (mark_object): Likewise for windows and frames.
3703 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3705 * alloc.c (valid_lisp_object_p): Treat killed buffers,
3706 buffer_defaults and buffer_local_symbols as valid objects.
3707 Return special value to denote them.
3709 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
3711 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
3712 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
3713 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
3714 (file_name_absolute_p, Fsubstitute_in_file_name):
3715 (check_executable, check_writable, Ffile_accessible_directory_p)
3716 (Fset_file_selinux_context, Fdefault_file_modes)
3717 (Finsert_file_contents, choose_write_coding_system)
3718 (Fwrite_region, build_annotations, a_write, e_write)
3720 * filelock.c (boot_time_initialized, get_boot_time)
3721 (get_boot_time_1, lock_file_1, within_one_second):
3722 * floatfns.c (in_float):
3723 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
3724 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
3725 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
3726 * lisp.h (struct Lisp_Hash_Table.cmpfn):
3727 * window.c (compare_window_configurations):
3728 Use bool for booleans.
3729 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
3730 (Fdefault_file_modes): Now mode_t, not int, for modes.
3731 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
3732 (internal_delete_file): Now returns void, not a (boolean) int,
3733 since nobody was looking at the return value.
3734 * lisp.h, window.h: Adjust to above API changes.
3736 * xdisp.c (set_message): Simplify and reindent last change.
3738 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
3740 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
3742 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
3744 * eval.c (call_debugger): Make the function non-static so that we
3745 can call it from set_message.
3747 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
3748 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
3750 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3752 Give more-useful info on a fatal error (Bug#12328).
3753 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
3754 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
3755 of doing the work ourselves.
3756 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
3757 do most of the work.
3758 (fatal_error_backtrace): New function, taken from the guts
3759 of the old fatal_error_signal, but with a new option to output
3761 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
3762 info about the signal than just its number.
3763 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
3764 * sysdep.c: Include <execinfo.h>
3765 (emacs_backtrace): New function, taken partly from the previous
3766 code of the 'die' function.
3767 (emacs_abort): Call fatal_error_backtrace rather than abort.
3769 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
3771 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
3772 eager (load-time) macro-expansion.
3773 * lisp.mk (lisp): Add macroexp.
3775 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3777 Simplify redefinition of 'abort' (Bug#12316).
3778 Do not try to redefine the 'abort' function. Instead, redo
3779 the code so that it calls 'emacs_abort' rather than 'abort'.
3780 This removes the need for the NO_ABORT configure-time macro
3781 and makes it easier to change the abort code to do a backtrace.
3782 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
3783 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
3784 Remove; sysdep.c's emacs_abort now takes its place.
3785 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
3786 'abort' changed to use 'emacs_abort'.
3787 * msdos.c (dos_abort) [defined abort]: Remove; not used.
3788 (abort) [!defined abort]: Rename to ...
3789 (emacs_abort): ... new name.
3790 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
3791 the place of the old 'abort' in emacs.c.
3792 * w32.c, w32fns.c (abort): Do not #undef.
3793 * w32.c (emacs_abort): Rename from w32_abort.
3795 2012-09-04 Eli Zaretskii <eliz@gnu.org>
3797 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
3798 offsets[j].dv, since the y axis of the screen coordinates points
3799 down, while the y axis of the font definition coordinates points
3800 up. This fixes display of Arabic diacritics such as KASRA and
3801 KASRATAN. (Bug#11860)
3803 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3805 Be more systematic about _setjmp vs setjmp.
3806 * alloc.c (test_setjmp, mark_stack):
3807 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
3808 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
3809 (png_load, my_error_exit, jpeg_load):
3810 * process.c (send_process_trap, send_process):
3811 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
3812 The underscored versions are up to 30x faster on some hosts.
3813 Formerly, the code used setjmp+longjmp sometimes and
3814 _setjmp+_longjmp at other times, with no particular reason to
3815 prefer setjmp+longjmp.
3817 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
3819 Fix minor problem found by static checking.
3820 * buffer.c (Fdelete_all_overlays): Return nil.
3822 2012-09-03 Martin Rudalics <rudalics@gmx.at>
3824 * buffer.c (Fdelete_all_overlays): New function.
3826 2012-09-03 Chong Yidong <cyd@gnu.org>
3828 * gtkutil.c: Add extern decl for Qxft.
3830 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
3832 * emacs.c, eval.c: Use bool for boolean.
3833 * emacs.c (initialized, inhibit_window_system, running_asynch_code):

3841 * process.c (read_process_output, exec_sentinel):
3842 Use bool for booleans.
3843 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
3844 All callers changed.
3845 * eval.c (interactive_p): Omit always-true boolean argument
3846 EXCLUDE_SUBRS_P. All callers changed.
3847 * dispextern.h, lisp.h: Reflect above API changes.
3848 * firstfile.c (dummy): Use the address of 'main', whose signature
3849 won't change, instead of the address of 'initialize', whose
3850 signature just changed from int to bool.
3851 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
3852 * msdos.c (fatal_error_in_progress): ... from here.
3853 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
3855 (redisplay_internal, unwind_redisplay): Simply clear
3856 REDISPLAYING_P when unwinding, instead of saving its previous,
3857 always-false value and then restoring it.
3859 Clean up some extern decls.
3860 Mostly, this hoists extern decls out of .c files and into .h files.
3861 That way, we're more likely to catch errors if the interfaces change.
3862 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
3863 declare xg_mark_data.
3864 * dispextern.h (x_frame_parm_handlers):
3866 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
3867 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
3868 (Qultra_bold, Qoblique, Qitalic):
3869 Move extern decl here from .c file.
3870 * alloc.c (xg_mark_data) [USE_GTK]:

3879 * process.c (QCfamily, QCfilter):
3880 * widget.c (free_frame_faces):
3881 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
3882 * xfont.c (x_clear_errors):
3883 * xterm.c (x_frame_parm_handlers):
3884 Remove now-redundant extern decls.
3885 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
3886 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
3888 * xfaces.c: Remove unnecessary static decls.
3889 * xterm.c (updating_frame): Remove decl of nonexistent object.
3891 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
3892 when building globals.h, as the objects that are not built on
3893 this host are not needed to compile C files on this host.
3895 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
3897 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

3905 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
3906 (Fsubstitute_command_keys):

3910 (format_time_string, general_insert_function)
3911 (make_buffer_string, make_buffer_string_both)
3912 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):
3913 * insdel.c (check_markers, gap_left, adjust_markers_for_insert)

3924 (set_intervals_multibyte_1, set_intervals_multibyte):
3925 * keyboard.c (decode_timer):
3926 Use bool for boolean.
3927 * intervals.h, lisp.h, systime.h: Reflect above API changes.

3930 2012-09-02 Chong Yidong <cyd@gnu.org>
3932 * keymap.c (push_key_description): Print M-TAB as C-M-i
3935 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
3937 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
3938 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

3943 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
3945 2012-09-01 Eli Zaretskii <eliz@gnu.org>
3947 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
3948 more than one grapheme cluster passed to the shaper: compute the
3949 offset adjustment values separately for each cluster. (Bug#11860)
3951 * image.c: Restore mistakenly removed inclusion of w32.h. Without
3952 it, GCC doesn't see prototypes of w32_delayed_load, and complains
3953 about implicit conversions from integer to pointer.
3955 2012-09-01 Daniel Colascione <dancol@dancol.org>
3957 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
3958 system used too early.
3960 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
3962 Better seed support for (random).

3986 directly accessing frame internals.
3988 * w32font.h: Include font.h. Define syms_of_w32font and
3991 * process.c: Include TERM_HEADER instead of listing all possible
3992 window-system headers.
3994 * nsterm.h: Remove declarations now in frame.h.
3995 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
3997 * menu.c: Include TERM_HEADER instead of listing all possible
3998 window-system headers.
4000 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
4003 * keyboard.c: Include TERM_HEADER instead of listing all possible
4004 window-system headers.
4006 * image.c: Include TERM_HEADER instead of listing all possible
4007 window-system headers. Declare Vlibrary_cache when compiling for
4010 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
4011 window system declarations.
4013 * frame.h: Move common functions here: set_frame_menubar,
4014 x_set_window_size, x_sync, x_get_focus_frame,
4015 x_set_mouse_position, x_set_mouse_pixel_position,
4016 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,
4017 x_char_width, x_char_height, x_pixel_width, x_pixel_height,

4037 the current window system; include in list of objects to link into
4040 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
4042 Remove mark_ttys function and fix tty_display_info initialization.
4043 * lisp.h (mark_ttys): Remove prototype.
4044 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
4045 to mark_ttys because all possible values of 'top_frame' slot are
4046 the frames which are reachable from Vframe_list.
4047 * term.c (mark_ttys): Remove.
4048 (init_tty): Safely initialize 'top_frame' slot with Qnil.
4050 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
4052 Change struct frame bitfields from unsigned char to unsigned.
4053 * frame.h (struct frame): Change type of 'display_preempted',
4054 'visible', 'iconified', 'has_minibuffer', 'wants_modeline',
4055 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
4056 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
4057 bitfields from unsigned char to unsigned.
4059 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
4061 Remove unused member of struct x_output and struct w32_output.

4065 2012-08-30 Jan Djärv <jan.h.d@swipnet.se>
4067 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
4068 does not become zero (Bug#12234).
4070 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
4072 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
4073 for GCC 4.7.1 x86-64.
4075 2012-08-30 Glenn Morris <rgm@gnu.org>
4077 * lread.c (init_lread): For out-of-tree builds, only add the
4078 source directory's site-lisp dir to the load-path if it exists,
4079 consistent with in-tree builds. (Bug#12302)
4081 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
4083 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize
4084 button_values to NULL. Call setStykeMask so dialogs get a close button.
4085 (windowShouldClose:): Set window_closed.
4086 (dealloc): New member, free button_values.
4087 (process_dialog:): Make member function. Remove window argument,
4088 replace window with self. Count buttons and allocate and store values
4090 (addButton:value:row:): value is int with the name tag. Call setTag
4091 with tag. Remove return self, declare return value as void.
4092 (addString:row:): Remove return self, declare return value as void.
4093 (addSplit): Remove return self, declare return value as void.
4094 (clicked:): Remove return self, declare return value as void.
4095 Set dialog_return to button_values[seltag]. Code formatting change.
4096 (initFromContents:isQuestion:): Adjust call to process_dialog.
4097 Code formatting change.
4098 (timeout_handler:): Set timer_fired to YES.
4099 (runDialogAt:): Set timer_fired to NO.
4100 Handle click on close button as quit.
4102 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
4103 Add window_closed and button_values. Add void as return value for
4104 add(Button|String|Split). addButton takes int instead of Lisp_Object.
4105 Add process_dialog as new member.
4107 2012-08-28 Eli Zaretskii <eliz@gnu.org>
4109 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
4110 is not one of the heaps we manage. (Bug#12242)
4112 2012-08-28 Glenn Morris <rgm@gnu.org>
4114 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)
4116 2012-08-28 Martin Rudalics <rudalics@gmx.at>
4118 * window.c (Fset_window_configuration): Remove handling of

4125 * buffer.c (Fset_buffer_major_mode): Signal an error
4126 if the buffer is dead.
4127 (Fother_buffer, other_buffer_safely): Remove redundant
4130 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
4132 Always use set_buffer_if_live to restore original buffer at unwind.
4133 * buffer.h (record_unwind_current_buffer): New function.
4134 * bytecode.c, dispnew.c, editfns.c, fileio.c, fns.c, insdel.c:
4135 * keyboard.c, keymap.c, minibuf.c, print.c, process.c, textprop.c:
4136 * undo.c, window.c: Adjust users.
4137 * buffer.c (set_buffer_if_live): Fix comment.
4139 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
4141 Fix usage of set_buffer_internal.
4142 * buffer.h (set_buffer_internal): Make it BUFFER_INLINE.
4143 * buffer.c (set_buffer_if_live): Use set_buffer_internal.
4144 * coding.c (decode_coding): Omit redundant test.
4145 * fileio.c (decide_coding_unwind): Likewise.
4146 * fns.c (secure_hash): Likewise.

4148 * keyboard.c (command_loop_1): Likewise.
4149 * print.c (PRINTFINISH): Likewise.
4150 * xdisp.c (run_window_scroll_functions): Use set_buffer_internal.
4152 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>

4172 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
4173 and remove last int (actually boolean) argument, which was always 0.
4174 All callers changed.
4175 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
4176 * dispextern.h (struct composition_it): Use bool for boolean.
4177 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
4178 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
4179 * dired.c (file_name_completion):
4180 Use bool for boolean. (This was missed in an earlier change.)
4182 2012-08-27 Martin Rudalics <rudalics@gmx.at>
4184 * window.c (Fset_window_configuration): Revert first part of
4187 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
4189 * nsterm.h (NSPanel): New class variable dialog_return.
4191 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
4192 Initialize dialog_return.
4193 (windowShouldClose:): Use stop instead of stopModalWithCode.
4194 (clicked:): Ditto, and also set dialog_return (Bug#12258).
4195 (timeout_handler:): Use stop instead of abortModal. Send a dummy
4197 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when

4242 Use bool for booleans.
4243 * coding.h, lisp.h: Reflect above API changes.
4244 * coding.c: Remove unnecessary static function decls.
4245 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
4246 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
4247 not a boolean 'int', since callers never look at the return value.
4248 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
4249 * coding.h (decoding_buffer_size, encoding_buffer_size)
4250 (emacs_mule_string_char): Remove unused extern decls.
4251 (struct iso_2022_spec, struct coding_system):
4252 Use 'unsigned int : 1' for boolean fields, since there's more than one.
4253 (struct emacs_mule_spec): Remove unused field 'full_support'.
4254 All initializations removed.
4255 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
4257 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
4259 Fix spare memory change (Bug#12286).
4260 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
4261 (valid_lisp_object_p): Likewise.
4263 2012-08-27 Martin Rudalics <rudalics@gmx.at>
4265 * window.c (Fset_window_configuration): Record any window's old
4266 buffer if it's replaced (see Bug#8789). If the new current
4267 buffer doesn't appear in the selected window, go to its old
4270 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
4272 Special MEM_TYPE_SPARE to denote reserved memory.
4273 * alloc.c (enum mem_type): New memory type.
4274 (refill_memory_reserve): Use new type for spare memory.
4275 This prevents live_cons_p and live_string_p from incorrect
4276 detection of uninitialized objects from spare memory as live.
4278 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
4281 * Makefile.in (.PHONY): versioclean -> versionclean.
4283 Remove unused external symbols.
4284 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
4285 * window.c (Qwindow_valid_p, decode_valid_window):
4286 Now static, not extern.
4287 * data.c (Qinterval): Remove; unused.
4288 (syms_of_data): Do not define 'interval'.
4289 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
4290 * window.h (decode_valid_window):
4293 * character.c, charset.c, chartab.c: Use bool for booleans.

4304 (map_sub_char_table):
4305 Use bool for boolean.
4306 * character.c (str_to_unibyte): Omit last boolean argument; it was
4307 always 0. All callers changed.
4308 * character.h, charset.h: Adjust to match previous changes.
4309 * character.h (char_printable_p): Remove decl of nonexistent function.
4310 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
4311 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
4312 are all boolean, so make them single-bit bitfields.
4314 * lisp.h (ASET): Remove attempt to detect side effects.
4315 It was meant to be temporary and it often doesn't work,
4316 because when IDX has side effects the behavior of IDX==IDX
4317 is undefined. See Stefan Monnier in
4318 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
4320 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
4322 * lisp.h (functionp): New function (extracted from Ffunctionp).
4323 (FUNCTIONP): Use it.
4324 * eval.c (Ffunctionp): Use it.
4326 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
4328 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
4329 as that's faster and simpler than static storage. Don't bother
4330 with the g_main_context_query overhead if g_main_context_pending
4331 says no events are pending.
4332 (gfds, gfds_size): Remove these static vars.
4333 (xgselect_initialize): Remove; no longer needed.
4334 All uses and decls removed.
4336 * emacs.c (fatal_error_signal_hook): Remove.
4337 All uses removed. This leftover from old code was always 0.
4339 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
4340 * casefiddle.c (casify_object, casify_region):
4341 * casetab.c (set_case_table):
4342 * category.c, category.h (word_boundary_p):
4343 * category.h (CHAR_HAS_CATEGORY):
4344 Use bool for booleans, instead of int.
4346 2012-08-25 Eli Zaretskii <eliz@gnu.org>
4348 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
4350 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
4352 On assertion failure, print backtrace if available.
4353 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
4354 (die) [ENABLE_CHECKING]: Print a backtrace if available.
4355 * Makefile.in (LIB_EXECINFO): New macro.
4358 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
4359 * bytecode.c (exec_byte_code):
4360 * callint.c (check_mark, Fcall_interactively):
4361 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
4362 (getenv_internal, sync_process_alive, call_process_exited):
4363 * lisp.h (USE_SAFE_ALLOCA):
4364 Use bool for booleans, instead of int.
4365 * lisp.h, process.h: Adjust prototypes to match above changes.
4366 * callint.c (Fcall_interactively): Don't assume the mark's
4367 offset fits in 'int'.
4369 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
4371 * buffer.c, buffer.h: Use bool for boolean.

4378 (mmap_enlarge, mmap_set_vars):
4379 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
4380 Use bool for booleans, instead of int.
4381 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
4382 since the 1-or-0 return value is always ignored anyway.
4383 (mmap_initialized_p):
4384 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
4385 * buffer.h, lisp.h: Adjust prototypes to match above changes.
4387 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
4389 * bidi.c: Use bool for boolean.
4390 This is a bit more readable, and makes the text segment of bidi.o
4391 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
4392 Presumably it's faster too.
4393 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
4395 (bidi_cache_find_level_change, bidi_cache_iterator_state)
4396 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)

4398 (bidi_explicit_dir_char, bidi_level_of_next_char)
4399 (bidi_find_other_level_edge, bidi_move_to_visually_next):
4400 Use bool for booleans, instead of int.
4401 * dispextern.h (bidi_init_it, bidi_paragraph_init)
4402 (bidi_unshelve_cache): Adjust decls to match code.
4404 2012-08-23 Martin Rudalics <rudalics@gmx.at>
4406 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
4409 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
4411 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
4412 * atimer.h: Include <stdbool.h>.
4414 2012-08-22 Dan Nicolaescu <dann@gnu.org>
4416 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
4417 compile time tests instead of run time tests on systems that do
4419 (FRAME_MAC_P): Remove leftover from deleted code.
4420 * frame.c (syms_of_frame): Remove leftover from deleted code.
4422 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
4424 * nsterm.m (insertText:): Don't clear modifiers if code is space.
4426 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
4428 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
4429 Otherwise, the compiler complains about (A?B:C) where B is void
4430 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
4431 (fontset_add): Return void, for FONTSET_ADD.
4433 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4435 * alloc.c: Use bool for booleans.
4436 (gc_in_progress, abort_on_gc)
4437 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
4438 (dont_register_blocks) [GC_MALLOC_CHECK]:
4439 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
4440 (check_string_bytes, make_specified_string, memory_full)
4441 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
4442 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
4443 (mark_stack, valid_pointer_p, make_pure_string)
4444 (Fgarbage_collect, survives_gc_p, gc_sweep):
4445 Use bool for booleans, instead of int.
4446 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
4447 Remove unused local.
4448 * alloc.c (PURE_POINTER_P):
4449 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
4450 * editfns.c (Fformat):
4451 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
4453 * fns.c (sweep_weak_table):
4454 * lisp.h (suppress_checking, push_message, survives_gc_p)
4455 (make_pure_string, gc_in_progress, abort_on_gc):
4456 * lread.c (readchar, read1):
4457 * print.c (Fprin1_to_string):
4458 * xdisp.c (push_message):
4459 Use bool for booleans affected directly or indirectly by
4462 Make recently-introduced setters macros.
4463 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
4464 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
4465 (set_fontset_default, set_fontset_fallback): Rename from their
4466 upper-case counterparts, and make them functions rather than macros.
4467 This is more consistent with the other recently-introduced setters.
4468 These don't need to be inline, since they're local.
4470 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
4472 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
4473 the loop (Bug#12247).
4475 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4477 * lisp.h (vcopy): Use memcpy rather than our own loop.
4478 This fixes a performance regression introduced by the recent
4479 addition of vcopy. This means 'vcopy' will need to be modified
4480 for a copying collector, but that's OK. Also, tighten the
4481 checking in the assertion.
4483 2012-08-21 Eli Zaretskii <eliz@gnu.org>
4485 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
4486 components for RTL text (Bug#11860). Adjust X-OFFSET of each
4487 non-base glyph for the width of the base character, according to
4488 what x_draw_composite_glyph_string_foreground expects.
4489 Generate WADJUST value according to composition_gstring_width's
4490 expectations, to produce correct width of the composed character.
4491 Reverse the sign of the DU offset produced by ScriptPlace.
4493 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4495 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
4497 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
4499 Avoid direct writes to contents member of struct Lisp_Vector.
4500 * lisp.h (vcopy): New function to copy data into vector.
4501 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
4502 * fns.c (Ffillarray): Use ASET.
4503 * keyboard.c (timer_check_2): Use AREF and ASET.
4504 (append_tool_bar_item, Frecent_keys): Use vcopy.
4505 * lread.c (read_vector): Use ASET.
4506 * msdos.c (Frecent_doskeys): Use vcopy.
4507 * xface.c (Finternal_copy_lisp_face): Use vcopy.
4508 (Finternal_merge_in_global_face): Use ASET and vcopy.
4509 * xfont.c (xfont_list_pattern): Likewise.
4511 2012-08-21 Martin Rudalics <rudalics@gmx.at>
4513 * window.c (Fwindow_point): For the selected window always return
4514 the position of its buffer's point.
4515 (Fset_window_point): For the selected window always go in its
4516 buffer to the specified position.
4518 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
4520 Setter macros for fontsets.
4521 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
4522 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
4523 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
4526 2012-08-20 Glenn Morris <rgm@gnu.org>
4528 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
4529 Don't assume that `ln -f' works.
4531 2012-08-20 Eli Zaretskii <eliz@gnu.org>
4533 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
4534 and later about non-assignments with no effect. See discussion at

4559 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
4560 (set_hash_hash, set_hash_index): Rename with _slot suffix.

4577 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
4579 Rely on <config.h> + <unistd.h> to declare 'environ',
4580 as gnulib does this if the system doesn't.
4581 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
4582 Remove declaration. MS-Windows declares it on stdlib.h which is

4585 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.

4616 * chartab.c, lisp.h (char_table_set, char_table_set_range):
4617 Return void, not Lisp_Object. Otherwise, the compiler
4618 complains about (A?B:C) where B is void and C is Lisp_Object

5450 2012-08-04 Eli Zaretskii <eliz@gnu.org>
5452 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
5453 * w32.c (init_environment): Change the default values of many
5454 environment variables in dflt_envvars[] to NULL, to avoid pushing
5455 them into environment when they were not already defined.
5456 Remove the code that deletes site-lisp subdirectories from the default
5457 value of EMACSLOADPATH, as it is no longer needed.
5458 (check_windows_init_file): Now external, not static.
5459 Use Vload_path as is, without adding anything, as this function is now
5460 called when Vload_path is already set up.
5462 * w32.h (check_windows_init_file): Add prototype.
5464 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
5465 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
5466 compatibility with Posix platforms.
5467 (main): Move the call to check_windows_init_file to here from
5469 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
5470 any, in the DEFALT argument into the root of the Emacs build or
5471 installation tree, as appropriate.
5473 * callproc.c (init_callproc_1): Call decode_env_path instead of
5474 doing its equivalent by hand.
5475 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
5476 the code that sets Vexec_path run on MS-Windows.
5478 * lread.c (init_lread): Add comments to #ifdef's.
5480 * msdos.c (dos_set_window_size, IT_update_begin)
5481 (IT_frame_up_to_date, IT_set_frame_parameters): Use FVAR and WVAR
5482 instead of direct references.

5487 * lisp.h (DEFAULT_REHASH_THRESHOLD, DEFAULT_REHASH_SIZE):
5488 Now constants, not macros.
5490 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
5492 Remove unnecessary casts involving pointers.
5493 These casts are no longer needed now that we assume C89 or later,
5494 since they involve casting to or from void *.
5495 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
5496 (make_pure_float, make_pure_vector):
5497 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

5506 (x_get_window_property, x_get_window_property_as_lisp_data):
5507 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
5508 Remove unnecessary pointer casts.
5509 * alloc.c (record_xmalloc): New function.
5510 * lisp.h (record_xmalloc): New decl.
5511 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
5512 more like a function. This is because the pointer cast is not
5513 needed. All uses changed.
5514 * print.c (print_string, print_error_message): Avoid length recalc.
5516 Improve fix for macroexp crash with debugging (Bug#12118).
5517 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
5518 ARRAY_MARK_FLAG when checking subscripts, because ASET is
5519 not supposed to be invoked from the garbage collector.
5520 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
5521 (gc_aset): New function, which is like ASET but can be
5522 used in the garbage collector.
5523 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

5533 <g_b_init_create_symbolic_link>: New static flags.
5534 (globals_of_w32): Initialize them to zero.
5535 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
5536 (map_w32_filename): Improve commentary. Simplify switch.
5537 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
5538 headers (most versions of MinGW w32api don't).
5539 (get_security_info, create_symbolic_link)
5540 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
5542 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
5543 in the argument file name.

5546 (sys_rename): Diagnose renaming of a symlink when the user doesn't
5547 have the required privileges.
5548 (get_file_security_desc_by_name): Rename from
5549 get_file_security_desc.
5550 (stat_worker): New function, with most of the guts of 'stat', and
5551 with addition of handling of symlinks and support for 'lstat'.
5552 If possible, get file's attributes and security information by
5553 handle, not by name. Produce S_IFLNK bit for symlinks, when
5554 called from 'lstat'.
5555 (stat, lstat): New functions, call 'stat_worker'.
5556 (symlink, readlink, careadlinkat): Rewritten to create and resolve
5557 symlinks when the underlying filesystem supports them.
5559 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
5561 Fix macroexp crash on Windows with debugging (Bug#12118).
5562 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
5563 checking subscripts; problem introduced with the recent
5564 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
5565 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
5566 since it's used in non-static inline functions now.
5568 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
5569 Don't assume buffer size fits in 'int'. Remove unused local.
5571 Use C99-style 'extern inline' if available.

5586 * category.c (CATEGORY_INLINE):
5587 * character.c (CHARACTER_INLINE):
5588 * charset.c (CHARSET_INLINE):
5589 * composite.c (COMPOSITE_INLINE):
5590 * dispnew.c (DISPEXTERN_INLINE):
5591 * sysdep.c (SYSTIME_INLINE):
5592 Define to EXTERN_INLINE, so that the corresponding functions
5593 are compiled into code.
5594 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
5595 (INLINE_HEADER_END): New macros.
5596 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

5616 hard-coding the path separator.
5618 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
5620 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
5621 This how ASET and AREF are supposed to work, and makes
5622 it easier to think about future improvements. See
5623 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
5624 * charset.h (set_charset_attr): New function.

5877 * s/aix4-2.h (sigmask): No need to undefine it, since syssignal.h
5878 does that unconditionally. Remove file, which is now empty.
5880 * s/freebsd.h, s/gnu-linux.h, s/sol2-6.h, s/unixware.h:
5883 2012-07-30 Paul Eggert <eggert@cs.ucla.edu>

6001 * w32inevt.c: Include w32inevt.h.
6002 (w32_read_console_input): New inline function, calls either
6003 ReadConsoleInputA or ReadConsoleInputW, depending on the value of
6004 w32_console_unicode_input.
6005 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
6006 (w32_kbd_patch_key, key_event): Use the codepage returned by
6007 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.
6008 (key_event): use uChar.UnicodeChar only if
6009 w32_console_unicode_input is non-zero.

6039 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
6040 enumeration constants, as PURE and HEAP are too general, and clash
6041 with other headers and sources, such as gmalloc.c and the
6042 MS-Windows system headers. All users changed.
6044 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
6046 Revert last save_excursion_save and save_excursion_restore changes.
6047 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

6057 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
6059 Improve GDB symbol export (Bug#12036).
6060 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
6061 arms of an 'if', not using conditional expressions; otherwise GDB
6062 complains about the types in the unevaluated arm when the argument
6063 is an integer literal.
6064 (xgetint): Simplify expression.
6065 * alloc.c (gdb_make_enums_visible): New constant. This ports to
6066 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
6067 Zaretskii in <http://bugs.gnu.org/12036#13>.
6068 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
6069 needed now that we have gdb_make_enums_visible.
6070 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
6071 (enum enum_USE_LSB_TAG):
6072 New enum types, packaging up enums that need to be exported to GDB.

6091 * xfns.c (syms_of_xfns): Likewise.
6093 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>

6096 * lisp.h (struct Lisp_Excursion): New data type.
6097 (PVEC_EXCURSION): New pseudovector type.
6098 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
6099 to deal with it. Adjust comments.

6110 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
6112 Fix export of symbols to GDB (Bug#12036).
6113 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
6114 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
6115 emacs.c, as this is a more-suitable home. Had this been done earlier
6116 the fix for 12036 would have avoided some of the problems noted in
6117 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
6118 would have been more obvious.
6119 * emacs.c: Do not include <verify.h>; no longer needed.
6120 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
6121 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
6122 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

6128 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
6129 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
6130 not be usable in #if. This simplifies things.
6132 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
6134 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
6136 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

6139 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
6140 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
6141 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
6142 Adjust to changes in lisp.h and emacs.c, by using
6143 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
6144 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
6145 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
6146 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
6147 instead of gdb_valbits.
6148 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
6149 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
6150 instead of gdb_array_mark_flag.
6151 (xboolvector): Get size from $->size, not $->header.size.
6152 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
6153 (xreload, hook-run, hookpost-run): Remove.
6154 * emacs.c: Include <verify.h>.
6155 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
6156 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
6158 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
6159 (gdb_USE_LSB_TAG): New enum constants.
6160 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
6161 Also define these as enum constants, so they're visible to GDB.
6162 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
6163 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
6164 as constants, so they're visible to GDB.
6165 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
6166 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
6167 Now enum constants, not macros, so they're visible to GDB.
6168 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
6169 more convenient now. All uses changed.
6170 (VALMASK) [USE_LSB_TAG]: Also define in this case.
6171 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
6173 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

6178 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
6180 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
6181 add argument, tune behavior, and adjust all callers.
6183 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
6185 Use typedef for EMACS_INT, EMACS_UINT.
6186 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
6187 than macros. This simplifies debugging in the usual case, since
6188 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
6189 and it allows expressions involving EMACS_INT casts.
6190 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
6192 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

6202 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
6204 Adjust buffer text indirection counters at the end of Fkill_buffer.
6205 * buffer.c (Fkill_buffer): Adjust indirection counters when the
6206 buffer is definitely dead. This should really fix an issue reported
6207 by Christoph Scholtes again. (Bug#12007).
6208 (init_buffer_once): Initialize indirection counters of
6209 buffer_defaults and buffer_local_symbols (for sanity and safety).
6211 2012-07-24 Eli Zaretskii <eliz@gnu.org>
6213 * xdisp.c (init_iterator): Don't compute dimensions of truncation
6214 and continuation glyphs on tooltip frames, leave them at zero.
6215 Avoids continued lines in tooltips. (Bug#11832)
6217 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
6219 Simplify copy_overlay.
6220 * buffer.c (copy_overlay): Simplify. Use build_marker.

6226 or invalid. (Bug#12025)
6228 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
6229 it signals an error when a tooltip frame is being created.
6231 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
6233 Cleanup miscellaneous objects allocation and initialization.
6234 * alloc.c (allocate_misc): Change to static. Add argument to
6235 specify the subtype. Adjust comment and users.
6236 (build_overlay): New function.
6237 * buffer.c (copy_overlays, Fmake_overlay): Use it.
6238 * lisp.h (struct Lisp_Overlay): Remove obsolete comment.
6239 (allocate_misc): Remove prototype.
6240 (build_overlay): Add prototype.
6242 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
6244 Swap buffer text indirection counters in Fbuffer_swap_text.
6245 * buffer.c (Fbuffer_swap_text): Swap indirections too.
6246 This avoids crash reported by Christoph Scholtes at
6247 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
6249 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
6251 * nsmenu.m (Popdown_data): New struct.
6252 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
6254 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
6255 (initWithContentRect): Make imgView and contentView non-static
6256 and autorelease them. Also autorelease img and matrix (Bug#12005).
6257 (dealloc): Remove (Bug#12005).
6259 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
6261 Adjust consing_since_gc when objects are explicitly freed.
6262 * alloc.c (GC_DEFAULT_THRESHOLD): New macro.
6263 (Fgarbage_collect): Use it. Change minimum to 1/10 of default.
6264 (free_cons, free_misc): Subtract object size from consing_since_gc.
6266 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
6268 Simplify and cleanup markers positioning code.

6270 (live_buffer, set_marker_internal): New function.
6271 (Fset_marker, set_marker_restricted): Use set_marker_internal.
6272 (set_marker_both, set_marker_restricted_both): Use live_buffer.
6274 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
6276 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
6277 as it's limited by the amount of memory, not by INT_MAX.
6279 2012-07-21 Eli Zaretskii <eliz@gnu.org>
6281 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
6282 in special-event-map. See the discussion at
6283 http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00417.html
6286 * w32menu.c (add_menu_item): Cast to ULONG_PTR when assigning

7005 * s/aix4-2.h (unix): Remove; no longer needed.
7007 EMACS_TIME simplification (Bug#11875).
7008 This replaces macros (which typically do not work in GDB)

7010 The functional style also makes code easier to read and maintain.
7011 * systime.h: Include <sys/time.h> on all hosts, not just if
7012 WINDOWSNT, since 'struct timeval' is needed in general.

7052 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
7053 Prefer snprintf to strncpy.
7054 * nsterm.m (ns_term_init):
7055 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
7056 * nsterm.m (ns_term_init):
7057 Avoid the need for strncpy, by using build_string or
7058 make_unibyte_string directly. Use dtoastr, not snprintf.
7059 * process.c (Fmake_network_process): Diagnose service names that
7060 are too long, rather than silently truncating them or creating
7061 non-null-terminated names.
7062 (Fnetwork_interface_info): Likewise, for interface names.
7063 * sysdep.c (system_process_attributes) [GNU_LINUX]:

7078 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
7079 where argument type is known to be a Lisp_Cons.

7134 O_RDONLY already includes it).
7136 Stop ns builds setting the EMACSLOADPATH environment variable.
7137 * nsterm.m (ns_load_path): Rename from ns_init_paths.
7138 Now it does not set EMACSLOADPATH, just returns the load-path string.
7139 * nsterm.h: Update accordingly.
7140 * lread.c [HAVE_NS]: Include nsterm.h.
7141 (init_lread) [HAVE_NS]: Use ns_load_path.

7151 (ns_init_paths): Do not set EMACSPATH.
7152 * nsterm.h (ns_exec_path): Add it.

7204 (ns_init_paths): Do not set EMACSDATA, EMACSDOC.
7205 * nsterm.h (ns_etc_directory): Add it.
7206 * callproc.c [HAVE_NS]: Include nsterm.h.
7207 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
7209 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7211 Move marker debugging code under MARKER_DEBUG.
7212 * marker.c (MARKER_DEBUG): Move marker debugging code under
7213 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
7214 for bootstrap with --enable-checking (~3x slowdown reported
7215 by Juanma Barranquero <lekktu@gmail.com>).
7216 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
7218 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
7220 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
7221 See <http://bugs.gnu.org/11825#29>.
7223 2012-07-08 Eli Zaretskii <eliz@gnu.org>
7225 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
7226 has no font, use the frame's font. (Bug#11813)
7227 (display_line): Add commentary about displaying truncation glyphs
7229 (produce_special_glyphs): Move here from term.c.
7231 * term.c (produce_special_glyphs): Move to xdisp.c.
7233 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
7236 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
7238 * xdisp.c (display_line): Avoid warning about implicit declaration
7241 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
7243 * lisp.h: Remove empty conditional.
7245 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
7247 * lread.c (load_path_check): Now static.
7249 Fix some minor --with-ns problems found by static checking.
7250 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
7251 (x_set_font) [!HAVE_X_WINDOWS]:
7252 * image.c (xpm_load_image) [HAVE_NS]:
7253 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
7254 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
7255 Remove unused local.
7256 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
7257 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
7258 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
7259 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
7260 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):

7262 Fix pointer signedness problem.
7263 * xfaces.c (FRAME_X_FONT_TABLE):
7264 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
7266 2012-07-07 Glenn Morris <rgm@gnu.org>
7268 * lread.c (load_path_check): New function, split from init_lread.
7269 (init_lread): Reorganize. Motivation:
7270 If EMACSLOADPATH is set, check/warn about that rather than the
7271 defaults, which we are not going to use. Hence we can remove
7272 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
7273 Don't warn if site-lisp directories are missing.
7274 If not installed, start from a blank load-path, since
7275 PATH_LOADSEARCH refers to the eventual installation directories.
7277 2012-07-07 Eli Zaretskii <eliz@gnu.org>
7279 Support truncation and continuation glyphs on GUI frames, when
7280 fringes are disabled. (Bug#11832)
7281 * xdisp.c (init_iterator): Get dimensions of truncation and
7282 continuation glyphs even if on GUI frames.
7283 Adjust it->last_visible_x on GUI frames when the left or right fringes,
7284 or both, are absent.
7285 (start_display, move_it_in_display_line_to): Handle the case of a
7286 GUI frame without a fringe to display continuation or truncation
7288 (insert_left_trunc_glyphs): Support GUI frames: make sure
7289 truncation glyphs overwrite enough glyphs from the current line to
7290 have sufficient space in pixels.
7291 (display_line): Support truncation and continuation glyphs on GUI
7292 frames. If some spare pixels are left on the line after inserting
7293 the truncation glyphs, fill that space with a stretch glyph of a
7294 suitably computed width.
7296 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
7297 produce_glyphs, to support GUI sessions.
7299 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
7301 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
7303 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
7305 Do not require float-time's arg to fit in time_t (Bug#11825).
7306 This works better on hosts where time_t is unsigned, and where
7307 float-time is applied to the (negative) difference between two times.
7308 * editfns.c (decode_time_components): Last arg is now double *,
7309 not int *, and means to store all the result as a double, without
7310 worrying about whether the seconds part fits in time_t.
7311 All callers changed.
7312 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
7313 All callers changed.
7314 (Ffloat_time): Do not fail merely because the specified time falls
7315 outside of time_t range.
7317 2012-07-07 Glenn Morris <rgm@gnu.org>
7319 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

7325 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
7326 Update dependencies.
7328 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
7330 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7332 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
7333 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
7334 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
7335 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
7336 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
7337 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
7339 * xfont.c (compare_font_names): Redo to omit the need for casts.
7341 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
7343 * xfns.c (Fx_change_window_property): Doc fix.
7344 * w32fns.c (Fx_change_window_property): Doc fix.
7346 * w32fns.c (Fx_window_property): Accept the same arguments as the
7347 X Windows version. Doc fix.
7348 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
7350 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
7351 Eli Zaretskii <eliz@gnu.org>
7353 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
7354 Windows-specific code from nt/config.nt moved here.
7355 Obsolete settings removed.
7357 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7359 * process.c: Avoid unnecessary calls to gettime.
7360 (wait_reading_process_output): Don't get the time of day
7361 when gobbling data immediately and not waiting, as there's no need
7362 for it in that case. This removes a FIXME.
7364 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
7366 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
7367 is defined (Bug#11768).
7369 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7371 Fix marker debugging code.
7372 * marker.c (byte_char_debug_check): Do not perform the check
7373 if buffer is not multibyte.
7374 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
7375 Call byte_char_debug_check with correct arguments.
7377 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7379 Compile marker debugging code only if ENABLE_CHECKING is defined.
7380 * marker.c (byte_char_debug_check, count_markers):
7381 Use only if ENABLE_CHECKING is defined.
7382 (byte_debug_flag): Remove.
7383 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
7384 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
7386 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7388 Avoid code repetition in marker-related functions.
7389 * marker.c (attach_marker): New function.
7390 (Fset_marker, set_marker_restricted, set_marker_both)
7391 (set_marker_restricted_both): Use it.
7392 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
7393 Consistently rename charno to charpos.
7394 (marker_position): Add eassert.
7395 (marker_byte_position): Convert to eassert.
7397 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

7407 * lisp.h (build_marker): New prototype.
7408 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
7409 * composite.c (autocmp_chars): Likewise.
7410 * editfns.c (buildmark): Remove.
7411 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
7412 (save_restriction_save): Use build_marker.
7413 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
7414 * window.c (save_window_save): Likewise.
7416 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7418 Do not use Fdelete_overlay in delete_all_overlays
7419 to avoid redundant calls to unchain_overlay.
7420 * buffer.c (drop_overlay): New function.
7421 (delete_all_overlays, Fdelete_overlay): Use it.
7422 * minibuf.c (get_minibuffer): Fix comment.
7424 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7426 Port to OpenBSD 5.1 amd64.
7427 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
7428 This is needed for OpenBSD, and should be harmless on all BSD systems.
7429 Also, include <sys/sysctl.h>, as it should be available on all
7430 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
7431 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
7432 use p_pid member, not kp_proc.pid.
7434 2012-07-06 Glenn Morris <rgm@gnu.org>
7436 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
7438 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
7440 More xmalloc and related cleanup.
7441 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
7442 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

7447 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
7448 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
7449 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
7451 Omit needless casts involving void * pointers and allocation.
7452 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
7453 as the former is more robust if P's type is changed.
7454 Prefer xzalloc to xmalloc + memset 0.
7455 Simplify malloc-or-realloc to realloc.
7456 Don't worry about xmalloc returning a null pointer.
7457 Prefer xstrdup to xmalloc + strcpy.
7458 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
7460 * keyboard.c (apply_modifiers_uncached): Prefer local array to
7461 alloca of a constant.
7463 2012-07-05 Eli Zaretskii <eliz@gnu.org>
7465 * xdisp.c (display_line): Fix horizontal pixel coordinates when
7466 hscroll is larger than the line width. Fixes long and futile
7467 looping inside extend_face_to_end_of_line (on a TTY) producing
7468 glyphs that are not needed and thrown away.
7470 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
7472 * marker.c (set_marker_restricted_both): Simplify by using
7475 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
7477 * editfns.c (region_limit): Simplify by using clip_to_bounds.
7479 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
7481 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is

7484 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
7485 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
7486 followed by gtk_box_set_homogeneous (Bug#11768).
7487 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
7488 (update_theme_scrollbar_width, xg_create_scroll_bar):
7489 Use gtk_scrollbar_new (Bug#11768).
7490 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
7491 (is_box_type): New function (Bug#11768).
7492 (xg_tool_item_stale_p): Call is_box_type.
7493 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
7494 with default display (Bug#11768).
7496 2012-07-05 Eli Zaretskii <eliz@gnu.org>
7498 * xdisp.c (window_hscroll_limited): New function.
7499 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
7500 coordinates when window's hscroll is set to insanely large
7503 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
7505 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
7506 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
7508 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
7511 * lisp.h (xzalloc): New prototype. Omit needless casts.
7512 * alloc.c (xzalloc): New function. Omit needless casts.

7567 Problem reported by Troels Nielsen in
7568 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
7570 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7572 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
7573 This should be fixed in a better way; see Eli Zaretskii in
7574 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
7575 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
7577 * fileio.c (time_error_value): Rename from special_mtime.
7578 The old name's problems were noted by Eli Zaretskii in
7579 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
7581 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
7582 This variable's comment says Emacs needs at least one GDB-visible
7583 symbol of type enum pvec_type, to work around GDB problems.
7584 The symbol's value doesn't matter.
7586 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
7587 that causes compilation to fail on pre-C99 compilers.
7589 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
7591 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
7592 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
7594 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
7596 * buffer.c (init_buffer_once): Fix initialization of
7597 headers for buffer_defaults and buffer_local_symbols.
7598 Reported by Juanma Barranquero <lekktu@gmail.com>.
7600 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
7602 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
7603 * lisp.h (enum pvec_type): Use fewer bits.
7604 (PSEUDOVECTOR_SIZE_BITS): New constant.
7605 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
7606 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
7607 change in pvec_type.
7608 (PSEUDOVECTOR_TYPEP): New macro.
7609 (TYPED_PSEUDOVECTORP): Use it.
7610 * fns.c (internal_equal): Adapt code to extract pvectype.
7611 * emacs.c (gdb_pvec_type): Update type.
7612 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
7613 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
7614 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
7615 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
7616 (sweep_vectors): Use it. Use local var `total_bytes' instead of
7617 abusing vector->header.next.nbytes.
7618 (live_vector_p): Use PVEC_TYPE.
7619 (mark_object): Adapt code to extract pvectype. Use switch.
7621 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7623 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
7624 Tighten new eassert a bit.
7626 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
7628 Fix compilation with --enable-gcc-warnings and -O1
7630 * doprnt.c (doprnt): Change type of tem to int, initialize
7631 to avoid compiler warning. Add eassert.
7632 * search.c (simple_search): Initialize match_byte to avoid
7633 compiler warning. Add eassert.
7635 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7637 Avoid weird behavior with large horizontal scrolls.
7638 Without this change, for example, large hscroll values would
7639 mess up Emacs's display on Fedora 15 x86, presumably due to
7640 overflows in int calculations in the display code.
7641 Also, if buffers had long lines, Emacs would freeze.
7642 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
7643 (set_window_hscroll): New function, containing the old guts of
7644 Fset_window_hscroll. Return the clipped value.
7645 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
7646 This avoids the need to check against PTRDIFF_MAX.
7648 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
7650 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
7652 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
7654 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7656 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
7657 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
7658 since GCC 4.4.6 issues a bogus warning for them.
7660 Fix bugs in file timestamp newness comparisons.
7661 * fileio.c (Ffile_newer_than_file_p):
7662 * lread.c (Fload): Use full timestamp resolution of files,
7663 not just the 1-second resolution, so that files that are only
7664 slightly newer still count as newer.
7665 * fileio.c (Ffile_newer_than_file_p): Don't assume file
7666 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
7668 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
7670 * fileio.c: Improve handling of file time marker. (Bug#11852)
7671 (special_mtime): New function.
7672 (Finsert_file_contents, Fverify_visited_file_modtime):
7673 Use it to set special mtime values consistently.
7675 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
7677 * fileio.c (Finsert_file_contents): Properly handle st_mtime
7678 marker for non-existing file. (Bug#11852)
7680 2012-07-03 Glenn Morris <rgm@gnu.org>
7682 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
7683 and did not make it into globals.h).
7685 2012-07-03 Tom Tromey <tromey@redhat.com>
7687 * window.c (Fset_window_margins, Fset_window_fringes)
7688 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.

7731 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
7732 values which aren't power of 2.
7733 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
7734 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
7737 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
7739 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
7741 * alloc.c (mark_object): Revert part of last patch to use `switch'.
7743 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7745 * alloc.c (allocate_vector_block): Remove redundant
7746 calls to mallopt if DOUG_LEA_MALLOC is defined.
7747 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
7748 avoid calls to mallopt if zero_vector is returned.
7750 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7752 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
7753 is enabled, avoid dereferencing NULL current_sblock if
7756 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7758 Cleanup basic buffer management.
7759 * buffer.h (struct buffer): Change layout to use generic vector
7760 marking code. Fix some comments. Change type of 'clip_changed'
7761 to bitfield. Remove unused #ifndef old.
7762 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
7763 (GET_OVERLAYS_AT): Fix indentation.
7764 (for_each_per_buffer_object_at): New macro.
7765 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
7766 (Fbuffer_local_variables): Use it.
7767 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
7768 * alloc.c (allocate_buffer): Adjust to match new layout of
7769 struct buffer. Fix comment.
7770 (mark_overlay): New function.
7771 (mark_buffer): Use it. Use mark_vectorlike to mark normal
7772 Lisp area of struct buffer.
7773 (mark_object): Use it. Adjust marking of misc objects
7774 and related comments.
7776 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
7778 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
7779 wrapper that is not needed because the wrapped code is a no-op (zero
7780 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
7781 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
7783 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
7785 * alloc.c (mark_buffer): Simplify. Remove prototype.
7786 (mark_object): Add comment. Reorganize marking of vector-like
7787 objects. Use CHECK_LIVE for all vector-like objects except buffers
7788 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
7789 Avoid redundant calls to mark_vectorlike for bool vectors.
7791 2012-06-30 Glenn Morris <rgm@gnu.org>
7793 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
7795 * epaths.in (PATH_SITELOADSEARCH): New.
7796 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
7797 This is rather than relying on --enable-locallisppath elements
7798 having "site-lisp" in their names. (Bug#10208#25, 11658)
7800 2012-06-30 Eli Zaretskii <eliz@gnu.org>
7802 * w32proc.c (sys_select): Accept and ignore one more argument.
7804 * w32.c (emacs_gnutls_pull): Call select with one more argument.
7806 * sysselect.h [DOS_NT]: Don't include sys/select.h.
7807 (pselect) [!MS_DOS]: Redirect to sys_select.
7809 * sysdep.c: Don't include dos.h and dosfns.h.
7811 * process.c (sys_select):
7812 * msdos.c (sys_select): Accept one more argument and ignore it.
7814 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
7815 adapt data types and code to that.
7818 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
7819 which clashes with the gnulib function of the same name.
7821 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
7823 * font.c (font_style_to_value, font_style_symbolic)
7824 (font_prop_validate_style): Add type checks for values in
7827 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
7829 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
7832 2012-06-29 Eli Zaretskii <eliz@gnu.org>
7834 * xdisp.c (try_window_id): Undo last change.
7836 * w32.c (getwd): Adjust commentary about startup_dir.
7837 (init_environment): Always call sys_access, even in non-MSVC
7838 builds. Don't chdir to the directory of the Emacs executable.
7839 This undoes code from 1997 which was justified by the need to
7840 "avoid conflicts when removing and renaming directories". But its
7841 downside was that every relative file name was being interpreted
7842 relative to the directory of the Emacs executable, which can never
7843 be TRT. In particular, it broke sys_access when called with
7844 relative file names.
7845 (sys_access): Map GetLastError to errno.
7847 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
7849 * window.h (struct window): Change type of 'fringes_outside_margins'

7853 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
7856 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>

7859 Add QUIT to make the loop interruptible.
7861 2012-06-29 Glenn Morris <rgm@gnu.org>
7863 * charset.c (init_charset): Make lack of etc/charsets fatal.
7865 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
7867 * editfns.c (region_limit): Fix type mismatch.
7869 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
7871 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
7872 undefined. Convert from xassert to eassert.
7873 * nsmenu.m: Convert from xassert to eassert.
7874 * nsterm.m: Likewise.
7876 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
7878 * editfns.c (region_limit): Clip to narrowing (bug#11770).
7880 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
7882 Avoid integer overflow on scroll-left and scroll-right.
7883 * window.c (HSCROLL_MAX): New macro.
7884 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
7885 overflow when requested scroll falls outside ptrdiff_t range.
7887 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
7889 * window.h (struct window): Change type of 'hscroll',
7890 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
7891 'last_modified' and 'last_overlay_modified' to EMACS_INT.
7892 Adjust users accordingly.
7893 * xdisp.c (try_cursor_movement): Replace type check with eassert.
7894 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
7895 from EMACS_INT to ptrdiff_t.
7896 (make_window): Omit redundant initialization.
7898 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

7902 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
7904 * window.h (struct window): Change type of 'use_time' and

7967 avoid GCC warning about unused macro.

7971 * alloc.c (allocate_string): Omit intervals initialization.
7972 * alloc.c (make_uninit_multibyte_string): Initialize intervals
7973 as in make_pure_string and make_pure_c_string.
7975 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
7977 * alloc.c (allocate_string): Fix last change.
7979 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

8029 * alloc.c: Remove build_string.
8030 * lisp.h: Define build_string as static inline. This provides
8031 a better opportunity to optimize away calls to strlen when the
8032 function is called with compile-time constant argument.
8033 * image.c (imagemagick_error): Convert to build_string.
8034 * w32proc.c (sys_spawnve): Likewise.
8035 * xterm.c (x_term_init): Likewise.
8037 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
8039 Use sprintf return value instead of invoking strlen on result.
8040 In the old days this wasn't portable, since some sprintf
8041 implementations returned char *. But they died out years ago and
8042 Emacs already assumes sprintf returns int.
8043 Similarly for float_to_string.
8044 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
8045 * ccl.c (ccl_driver):
8046 * character.c (string_escape_byte8):

8049 * print.c (print_object):
8050 * xdisp.c (message_dolog):
8051 * xfns.c (syms_of_xfns):
8052 Use sprintf or float_to_string result to avoid need to call strlen.
8053 * data.c (Fnumber_to_string):
8054 Use make_unibyte_string, since the string must be ASCII.
8055 * lisp.h, print.c (float_to_string): Now returns int length.
8056 * term.c (produce_glyphless_glyph):
8057 Use sprintf result rather than recomputing it.
8059 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
8060 * Makefile.in (ALL_CFLAGS):
8061 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

8067 strcasecmp if available.

8092 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

8095 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
8097 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
8098 instead of truncating it to 63 (admittedly a generous limit).
8100 * process.c: Fix spelling and caps in comments.
8102 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
8104 * emacs.c (setpgrp): Remove definition, unused.

8228 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
8230 Support higher-resolution time stamps (Bug#9000).
8231 The time stamps are only nanosecond-resolution at the C level,
8232 since that's the best that any real-world system supports now.
8233 But they are picosecond-resolution at the Lisp level, as that's
8234 easy, and leaves room for future OS improvements.
8236 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
8239 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
8240 Don't get current time unless it's needed.
8242 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
8243 now provides it if it's absent.
8244 (start_atimer): Port to higher-res time stamps.
8245 Check for time stamp overflow. Don't get current time more
8246 often than is needed.
8248 * buffer.h (struct buffer): Buffer modtime now has high resolution.
8249 Include systime.h, not time.h.
8250 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
8252 * dired.c: Include stat-time.h.
8253 (Ffile-attributes): File times now have higher resolution.
8255 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
8256 (struct image): Timestamp now has higher resolution.
8258 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
8259 has at least microseconds now. All uses removed.
8260 (update_frame, update_single_window, update_window, update_frame_1)
8261 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
8262 (duration_to_sec_usec): Remove; no longer needed.
8264 * editfns.c (time_overflow): Now extern.

8270 (decode_time_components, lisp_seconds_argument): New functions.
8271 (make_time): Now static.
8272 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
8273 Report an error if the time is invalid, rather than having the caller
8276 * fileio.c: Include <stat-time.h>
8277 (Fcopy_file): Copy higher-resolution time stamps.
8278 Prefer to set the time stamp via a file descriptor if that works.

8280 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
8281 (Fvisited_file_modtime, Fset_visited_file_modtime):
8282 Support higher-resolution time stamps.
8284 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
8286 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
8288 * image.c (prepare_image_for_display, clear_image_cache)
8289 (lookup_image): Port to higer-resolution time stamps.
8291 * keyboard.c (start_polling, bind_polling_period):
8292 Check for time stamp overflow.
8293 (read_char, kbd_buffer_get_event, timer_start_idle)
8294 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
8295 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
8296 Port to higher-resolution time stamps. Do not assume time_t is signed.
8297 (decode_timer): New function. Timers are now vectors of length 9,
8298 not 8, to accommodate the picosecond component.
8299 (timer_check_2): Use it.
8301 * nsterm.m (select_timeout, timeval_subtract): Remove.
8302 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
8303 as they're a bit more accurate and handle overflow better.
8304 (ns_select): Change prototype to be compatible with pselect.
8305 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
8306 * nsterm.h (ns_select): Adjust prototype.
8308 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
8309 us-resolution time stamps.
8310 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
8312 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
8314 * lisp.h (time_overflow): New decl.
8315 (wait_reading_process_output): First arg is now intmax_t, not int,
8316 to accommodate larger waits.
8318 * process.h (struct Lisp_Process.read_output_delay):
8319 Now counts nanoseconds, not microseconds.
8320 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
8322 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
8323 (wait_reading_process_output):
8324 Port to ns-resolution time stamps.
8325 (Faccept_process_output, wait_reading_process_output):
8326 Check for time stamp overflow. Do not assume time_t is signed.
8327 (select_wrapper): Remove; we now use pselect.
8328 (Fprocess_attributes): Now generates ns-resolution time stamps.
8330 * sysdep.c: Include utimens.h. Don't include utime.h
8331 or worry about struct utimbuf; gnulib does that for us now.
8332 (gettimeofday): Remove; gnulib provides a substitute.
8333 (make_timeval): New function.
8334 (set_file_times): Now sets ns-resolution time stamps.
8335 New arg FD; all uses changed.
8336 (time_from_jiffies, ltime_from_jiffies, get_up_time)
8337 (system_process_attributes):
8338 Now returns ns-resolution time stamp. All uses changed.
8339 Check for time stamp overflow.
8341 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
8342 provides a substitute now.
8344 * systime.h: Include timespec.h rather than sys/time.h and time.h,
8345 since it guarantees struct timespec.
8346 (EMACS_TIME): Now struct timespec, so that we can support
8347 ns-resolution time stamps.
8348 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
8349 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
8350 (EMACS_USECS): Remove.
8351 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
8352 so multiply the arg by 1000 before storing it.
8353 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
8355 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
8356 Port to ns-resolution time stamps.
8357 (EMACS_TIME_NEG_P): Remove; replaced by....
8358 (EMACS_TIME_SIGN): New macro.
8359 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
8360 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
8361 (set_file_times, make_time, lisp_time_argument): Adjust signature.
8362 (make_timeval, make_lisp_time, decode_time_components): New decls.
8363 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
8364 that it mishandled time_t overflow. You can't compare by subtracting!
8365 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
8366 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
8368 * term.c: Include <sys/time.h>.
8369 (timeval_to_Time): New function, for proper overflow wraparound.

8374 (Fprimitive_undo): Use them when restoring time stamps.
8376 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
8377 (w32_get_internal_run_time):
8378 Port to higher-resolution Emacs time stamps.
8379 (ltime): Now accepts single 64-bit integer, as that's more convenient
8382 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
8384 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
8385 for compatibility with pselect. Support ns-resolution time stamps.
8387 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
8389 * xselect.c (wait_for_property_change, x_get_foreign_selection):
8390 Check for time stamp overflow, and support ns-resolution time stamps.
8392 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
8393 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
8394 (timeval_subtract): Remove; no longer needed.
8395 (XTflash, XTring_bell, x_wait_for_event):
8396 Port to ns-resolution time stamps. Don't assume time_t is signed.
8398 2012-06-22 Chong Yidong <cyd@gnu.org>

8402 2012-06-22 Eli Zaretskii <eliz@gnu.org>
8404 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
8405 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
8406 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
8407 staticidx goes up to 1597 out of 1600 = 0x640.)
8409 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
8411 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
8412 Otherwise, the umask might be mistakenly 0 while handling input signals.

8433 (unwind_format_mode_line): Restore them.
8434 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
8436 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
8437 since tty frames can be explicitly named.
8438 (prepare_menu_bars): Likewise.
8440 * term.c (Ftty_top_frame): New function.
8442 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

8445 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
8446 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
8447 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
8448 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
8449 (METER_1, METER_2): Simplify.

8455 2012-06-18 Martin Rudalics <rudalics@gmx.at>
8457 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
8458 gets killed during executing of this function (Bug#11665).
8459 Try to always return Qt when the buffer has been actually killed.
8460 (Vkill_buffer_query_functions): In doc-string say that functions
8461 run by this hook should not change the current buffer.
8463 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
8465 Fix recently-introduced process.c problems found by static checking.

8483 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
8485 * lisp.h (eassert): Assume C89 or later.
8486 This removes the need for CHECK.
8487 (CHECK): Remove. Its comments about always evaluating its
8488 argument were confusing, as 'eassert' typically does not evaluate
8491 * coding.c (produce_chars): Use ptrdiff_t, not int.
8493 * xterm.c (x_draw_underwave): Check for integer overflow.
8494 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

8646 * frame.c (delete_frame): Remove outdated comment.
8647 * w32fns.c (Fw32_register_hot_key): Use XLI instead of checking
8648 USE_LISP_UNION_TYPE.

8667 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
8668 * alloc.c (make_number) [!defined make_number]:

8672 * data.c (Fmake_variable_buffer_local, Fmake_local_variable):
8673 * ftfont.c (ftfont_driver): Use LISP_INITIALLY_ZERO.
8674 * lisp.h (USE_LSB_TAG): Allow the builder to compile with

8676 USE_LSB_TAG now is always defined to be either 0 or 1.
8678 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
8679 code works fine either way, and efficiency is not a concern here,
8680 as the union type is for debugging, not for production.
8681 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
8682 Use an inline function on all platforms when using the union type,
8683 since this is simpler and 'static inline' can be used portably
8685 (LISP_INITIALLY_ZERO): New macro.
8686 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
8687 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

8714 * s/gnu-kfreebsd.h, s/gnu-linux.h, s/gnu.h, s/hpux10-20.h:
8715 * s/irix6-5.h, s/ms-w32.h, s/msdos.h, s/template.h:

8756 dbus_type_is_basic if available.
8757 (xd_extract_signed, xd_extract_unsigned): Rename from
8758 extract_signed and extract_unsigned, respectively. Adapt callers.
8760 2012-06-09 Chong Yidong <cyd@gnu.org>

8769 * xdisp.c (vmessage): Treat frame message as multibyte.
8770 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
8771 would generate the diagnostic "Making \302\247 buffer-local while
8774 2012-06-08 Eli Zaretskii <eliz@gnu.org>
8776 * dispnew.c (showing_window_margins_p): Undo last change, which

8790 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
8792 2012-06-08 Eli Zaretskii <eliz@gnu.org>
8794 * alloc.c (allocate_vectorlike): Fix last change.
8796 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
8798 Block-based vector allocation of small vectors.
8799 * lisp.h (struct vectorlike_header): New field `nbytes',
8800 adjust comment accordingly.

8825 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
8827 * doprnt.c (doprnt): Truncate multibyte char correctly.
8828 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
8829 would mishandle a string argument "Xc" if X was a multibyte
8830 character of length 2: it would truncate after X's first byte
8831 rather than including all of X.
8833 2012-06-06 Chong Yidong <cyd@gnu.org>
8835 * buffer.c (word_wrap): Doc fix.

8884 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
8885 Convert pctcpu and pctmem to Lisp float properly.
8886 Let the compiler fold better, as 100.0/0x8000 is exact.
8888 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
8890 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
8893 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
8895 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
8897 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
8899 For a 'struct window', replace some Lisp_Object fields to
8900 bitfields where appropriate, remove unused fields.
8901 * window.h (struct window): Remove unused 'last_mark_x' and
8902 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
8903 change its type from Lisp_Object to bitfield.
8904 Change type of 'force_start', 'optional_new_start',
8905 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
8906 fields from Lisp_Object to bitfield. Adjust users accordingly.
8908 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
8910 Pacify gcc -Wdouble-precision when using Xaw.
8911 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
8912 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
8913 Use 'float' consistently, rather than 'float' in most places
8914 and 'double' in a couple of places.
8916 2012-05-31 Eli Zaretskii <eliz@gnu.org>
8918 * xdisp.c (handle_stop): Detect whether we have overlay strings
8919 loaded by testing it->current.overlay_string_index to be
8920 non-negative, instead of checking whether n_overlay_strings is
8921 positive. (Bug#11587)
8923 2012-05-31 Chong Yidong <cyd@gnu.org>
8925 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
8927 * doc.c (Fsubstitute_command_keys): Doc fix.
8929 2012-05-31 Eli Zaretskii <eliz@gnu.org>
8931 * search.c (search_buffer): Remove calls to
8932 r_alloc_inhibit_buffer_relocation, as it is now called by
8933 maybe_unify_char, which was the cause of relocation of buffer text
8936 2012-05-31 Eli Zaretskii <eliz@gnu.org>
8938 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
8939 for the duration of call to load_charset, to avoid problems with
8940 callers of maybe_unify_char that access buffer text through C
8943 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
8944 decrement the inhibition flag, instead of just setting or
8947 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
8949 Remove obsolete '#define static' cruft.
8950 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
8951 This #undef was "temporary" in 2000; it is no longer needed
8952 now that '#define static' has gone away.
8953 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
8954 (gray_bitmap_bits): Remove; no longer needed.
8955 All uses replaced with definiens.
8956 * xterm.c: Include "bitmaps/gray.xbm".
8958 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
8960 Clean up __executable_start, monstartup when --enable-profiling.
8961 The following changes affect the code only when profiling.
8962 * dispnew.c (__executable_start): Rename from safe_bcopy.
8963 Define only on platforms that need it.
8964 * emacs.c: Include <sys/gmon.h> when profiling.
8965 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
8966 (__executable_start): Remove decl, since lisp.h does it now.
8967 (safe_bcopy): Remove decl; no longer has that name.
8968 (main): Coalesce #if into single bit of code, for simplicity.

8998 Do not create empty overlays with the evaporate property (Bug#9642).
8999 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
9000 Bug#9642, but explicitly check that the buffer the overlay would
9001 be moved to is live and rearrange lines to make sure that errors
9002 will not put the overlay in an inconsistent state.
9003 (Fdelete_overlay): Cosmetics.
9005 2012-05-28 Eli Zaretskii <eliz@gnu.org>
9007 * w32term.c (my_bring_window_to_top): New function.
9008 (x_raise_frame): Use handle returned by DeferWindowPos, which

9019 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
9021 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
9022 This avoids undefined behavior that might cause the eassert
9023 to not catch an out-of-range value.
9025 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
9027 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

9039 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
9041 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
9042 Only r_alloc_inhibit_buffer_relocation needed to be added;
9043 the others were already declared.
9045 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
9046 before checking whether it's out of range. Put the check inside
9048 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
9050 2012-05-27 Ken Brown <kbrown@cornell.edu>
9052 * callproc.c (Fcall_process): Restore a line that was accidentally
9053 commented out in the 2011-02-13 change (bug#11547).

9057 * lisp.h [REL_ALLOC]: Add prototypes for external functions
9058 defined on ralloc.c.
9060 * buffer.c [REL_ALLOC]: Remove prototypes of
9061 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
9062 they are now on lisp.h.
9064 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
9066 * search.c (search_buffer): Use it to inhibit relocation of buffer
9067 text while re_search_2 is doing its job, because re_search_2 is
9068 passed C pointers to buffer text. (Bug#11519)
9070 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
9073 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
9074 state after an additional call to move_it_in_display_line_to, keep
9075 the values of it->max_ascent and it->max_descent found for the
9077 (pos_visible_p): Revert the comparison against bottom_y to what it
9078 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
9081 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
9083 Fix coding-related core dumps with gcc -ftrapv.
9084 The code was computing A - B, where A and B are pointers, and B is
9085 random garbage. This can lead to core dumps on platforms that
9086 have special pointer registers, and it also leads to core dumps on
9087 x86-64 when compiled with gcc -ftrapv. The fix is to compute
9088 A - B only when B is initialized properly.
9089 * coding.c (coding_set_source, coding_set_destination): Return void.
9090 (coding_change_source, coding_change_destinations): New functions,
9091 with the old behaviors of coding_set_source and coding_set_destination.
9092 All callers that need an offset changed to use these new functions.

9112 gen_help_event to produce help-echo message in the echo area.
9113 Call clear_mouse_face if mouse_face_hidden is set in the mouse
9116 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>

9119 with GCC 4.7.0 on x86-64.
9121 2012-05-26 Eli Zaretskii <eliz@gnu.org>
9123 * bidi.c (bidi_mirror_char): Revert last change: an int is
9124 definitely wide enough here.
9126 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
9128 Fix integer width and related bugs (Bug#9874).

9139 (allocate_pseudovector):
9140 Use int, not EMACS_INT, where int is wide enough.

9160 (Foverlay_recenter, last_overlay_modification_hooks_used)
9161 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
9162 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9163 (validate_region): Omit unnecessary test for b <= e,
9164 since that's guaranteed by the previous test.
9165 (adjust_overlays_for_delete): Avoid pos + length overflow.
9166 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
9167 (report_overlay_modification):
9168 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9169 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):

9178 not int, to avoid needless 32-bit limit on 64-bit hosts.
9179 (exec_byte_code): Use tighter memory-full test, one that checks
9180 for alloca overflow. Don't compute the address of the object just
9181 before an array, as that's not portable. Use EMACS_INT, not
9182 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
9183 * callint.c (Fcall_interactively):
9184 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

9196 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9197 (casify_object): Avoid integer overflow when overallocating buffer.
9198 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
9199 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
9200 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
9201 * category.h (CATEGORYP): Don't assume arg is nonnegative.
9202 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
9203 integers are now checked earlier. All uses replaced with XINT.
9205 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9206 For CCL_MapSingle, check that content and value are in int range.
9207 (ccl_driver, Fregister_code_conversion_map):
9208 Check that Vcode_version_map_vector is a vector.
9209 (resolve_symbol_ccl_program): Check that vector header is in range.
9210 Always copy the vector, so that we can check its contents reliably
9211 now rather than having to recheck each instruction as it's being
9212 executed. Check that vector words fit in 'int'.
9213 (ccl_get_compiled_code, Fregister_ccl_program)
9214 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
9215 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
9216 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
9217 contents are in range.
9218 (Fccl_execute_on_string): Check that status is in range.
9219 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
9220 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
9221 Accept and return EMACS_INT, not int, because callers can pass values

9227 (string_escape_byte8, Fget_byte):
9228 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9229 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
9230 avoid mishandling large integers.
9231 * character.h: Adjust decls to match defn changes elsewhere.

9240 (Fdefine_charset_internal): Check ranges here, more carefully.
9241 Don't rely on undefined behavior with signed left shift overflow.
9242 Don't assume unsigned int fits into fixnum, or that fixnum fits
9243 into unsigned int. Don't require max_code to be a valid fixnum;
9244 that's not true for gb10830 4-byte on a 32-bit host. Allow
9245 invalid_code to be a cons, for the same reason. Require code_offset
9246 to be a character. Avoid int overflow if max_char is close
9248 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
9249 this is intended anyway and avoids some undefined behavior.
9250 (load_charset_map): Pass unsigned, not int, as 2nd arg of
9251 INDEX_TO_CODE_POINT, as that's what it expects.
9252 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
9253 * charset.h (DECODE_CHAR): Return int, not unsigned;
9254 this is what was intended anyway, and it avoids undefined behavior.
9255 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
9256 integer-overflow issues.
9257 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
9258 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
9259 where the argument is EMACS_INT, and this behavior is not intended.
9260 * chartab.c (Fmake_char_table, Fset_char_table_range)
9261 (uniprop_get_decoder, uniprop_get_encoder):
9262 Don't assume fixnum fits in int.
9263 * cmds.c (move_point): New function, that does the gist of
9264 Fforward_char and Fbackward_char, but does so while checking
9265 for integer overflow more accurately.
9266 (Fforward_char, Fbackward_char): Use it.
9267 (Fforward_line, Fend_of_line, internal_self_insert)
9268 (internal_self_insert):
9269 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

9271 target_clm and actual_clm.

10050 2012-05-14 Glenn Morris <rgm@gnu.org>
10052 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").

10060 (report_error, report_error_1, make_hdr, copy_sym)
10061 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
10062 Make arguments const char *, not char *, to avoid violations of C
10063 standard and to fix some AIX warnings reported by Gilles Pion.
10065 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10067 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
10068 already have overlays loaded.
10069 (handle_single_display_spec): Before returning without displaying
10070 fringe bitmap, synchronize the bidi iterator with the main display
10071 iterator, by calling iterate_out_of_display_property.
10072 (iterate_out_of_display_property): Detect buffer iteration by
10073 testing that it->string is a Lisp string.
10074 (get_next_display_element): When the current object is exhausted,
10075 and there's something on it->stack, call set_iterator_to_next to
10076 proceed with what's on the stack, instead of returning zero.
10077 (set_iterator_to_next): If called at the end of a Lisp string,
10078 proceed to consider_string_end without incrementing string
10079 position. Don't increment display vector index past the end of
10080 the display vector. (Bug#11417)
10081 (pos_visible_p): Don't report a position visible when move_it_to
10082 stopped at the last line of window, which happens to be scanned
10083 backwards by the bidi iteration. (Bug#11464)
10085 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10087 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
10088 and right-margin display specs even if the spec is invalid or we
10089 are on a TTY, and thus unable to display on the fringes.
10090 That's because the text with the property will not be displayed anyway,
10091 so we need to signal to the caller that this is a "replacing"
10092 display spec. This fixes display when the spec is invalid or we
10095 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
10097 * unexaix.c (make_hdr): Fix typo in prototype.
10098 This bug broke the build on AIX. Problem reported by Gilles Pion.
10100 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
10102 * keyboard.c (kbd_buffer_get_event): Read special events also in
10103 batch mode. (Bug#11415)

10113 2012-05-12 Glenn Morris <rgm@gnu.org>
10115 * Makefile.in (MKDIR_P): New, set by configure.
10116 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.

10128 Update dependencies.
10130 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
10132 * xgselect.c (xg_select): Put maxfds+1 into a var.
10133 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
10135 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
10137 2012-05-10 Dave Abrahams <dave@boostpro.com>
10139 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
10140 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
10142 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
10144 * dbusbind.c (xd_registered_buses): New internal Lisp object.
10145 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
10146 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
10147 Initialize xd_registered_buses.
10149 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
10151 Untag more efficiently if USE_LSB_TAG.
10152 This is based on a proposal by YAMAMOTO Mitsuharu in
10153 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
10154 For an admittedly artificial (nth 8000 longlist) benchmark on
10155 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
10156 Emacs's overall text size by 1%.
10157 * lisp.h (XUNTAG): New macro.
10158 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
10159 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
10160 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
10161 * eval.c (Fautoload):
10162 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
10163 * frame.h (XFRAME): Use XUNTAG.
10165 Port recent dbusbind.c changes to 32-bit --with-wide-int.
10166 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
10167 Remove unportable assumptions about print widths of types like
10169 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
10170 intptr_t when converting between pointer and integer, to avoid GCC
10171 warnings about wrong width.
10173 2012-05-09 Eli Zaretskii <eliz@gnu.org>
10175 * w32proc.c (new_child): Force Windows to reserve only 64KB of
10176 stack for each reader_thread, instead of defaulting to 8MB
10177 determined by the linker. This avoids failures in creating
10178 subprocesses on Windows 7, see the discussion in this thread:
10179 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
10181 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
10183 Fix up display of the *Minibuf-0* buffer in the mini window.
10184 * keyboard.c (read_char): Don't clear the echo area if there's no
10186 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
10187 contents of *Minibuf-0*) if there's no message displayed in its stead.
10189 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
10191 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
10194 2012-05-06 Chong Yidong <cyd@gnu.org>

10198 2012-05-05 Jim Meyering <meyering@redhat.com>
10200 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
10202 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
10204 * data.c (PUT_ERROR): New macro.
10205 (syms_of_data): Use it. Add new error type `user-error'.
10206 * undo.c (user_error): New function.
10207 (Fprimitive_undo): Use it.
10208 * print.c (print_error_message): Adjust print style for `user-error'.
10209 * keyboard.c (user_error): New function.
10210 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
10212 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
10214 Do not limit current-time-string to years 1000..9999.
10215 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
10216 (Fcurrent_time_string): Support any year that is supported by the
10217 underlying localtime representation. Don't use asctime, as it
10218 has undefined behavior for years outside the range -999..9999.
10220 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
10222 Fix race conditions involving setenv, gmtime, localtime, asctime.
10223 Without this fix, interrupts could mess up code that uses these
10224 nonreentrant functions, since setting TZ invalidates existing
10225 tm_zone or tzname values, and since most of these functions return
10226 pointers to static storage.
10227 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
10228 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
10229 Grow the critical sections to include not just invoking
10230 localtime/gmtime, but also accessing these functions' results
10231 including their tm_zone values if any, and any related TZ setting.
10232 (format_time_string): Last arg is now struct tm *, not struct tm **,
10233 so that the struct tm is saved in the critical section.
10234 All callers changed. Simplify allocation of initial buffer, partly
10235 motivated by the fact that memory allocation needs to be outside
10236 the critical section.
10238 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
10240 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
10241 with RESET_INTERVAL.
10243 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
10244 Remove duplicated buffer name initialization.
10246 2012-05-02 Jim Meyering <jim@meyering.net>
10248 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
10250 * xfns.c (x_window): Use xstrdup (Bug#11375).
10252 2012-05-02 Eli Zaretskii <eliz@gnu.org>
10254 * xdisp.c (pos_visible_p): If already at a newline from the
10255 display string before the 'while' loop, don't walk back the glyphs
10256 from it3.glyph_row. Solves assertion violation when the display
10257 string begins with a newline (egg.el). (Bug#11367)
10259 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
10261 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
10264 2012-05-01 Glenn Morris <rgm@gnu.org>
10266 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
10267 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
10268 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
10269 All were removed before 23.1.
10271 * dispnew.c: Remove HAVE_LIBNCURSES test;
10272 it is always true on relevant platforms.
10274 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
10275 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
10277 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
10279 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
10281 * .gdbinit (xpr): Remove checks for no longer existing misc types.
10282 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
10285 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
10287 Do not avoid creating empty evaporating overlays (Bug#9642).
10288 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
10289 That is, do not delete an evaporating overlay if it becomes
10290 empty after its bounds are adjusted to fit within its buffer.
10291 This fix caused other problems, and I'm reverting it until we get
10292 to the bottom of them.
10294 2012-04-27 Chong Yidong <cyd@gnu.org>
10296 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
10298 2012-04-27 Eli Zaretskii <eliz@gnu.org>
10300 * xdisp.c (pos_visible_p): If the window start position is beyond
10301 ZV, start the display from buffer beginning. Prevents assertion
10302 violation in init_iterator when the minibuffer window is scrolled
10303 via the scroll bar.
10305 * window.c (window_scroll_pixel_based): Likewise.
10307 2012-04-27 Chong Yidong <cyd@gnu.org>
10309 * keymap.c (where_is_internal): Doc fix (Bug#10872).
10311 2012-04-27 Glenn Morris <rgm@gnu.org>
10313 * fileio.c (Fcopy_file, Fset_file_selinux_context):
10314 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
10316 2012-04-27 Eli Zaretskii <eliz@gnu.org>
10318 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
10319 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
10321 2012-04-26 Eli Zaretskii <eliz@gnu.org>
10323 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
10324 display element, check also the underlying string or buffer
10325 character. (Bug#11341)
10327 * w32menu.c: Include w32heap.h.
10328 (add_menu_item): If the call to AppendMenuW (via
10329 unicode_append_menu) fails, disable Unicode menus only if we are
10330 running on Windows 9X/Me.
10332 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
10334 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
10335 (xgetint): Add missing shift for LSB tags.
10337 2012-04-24 Martin Rudalics <rudalics@gmx.at>
10339 * keyboard.c (read_char): Don't wipe echo area for select window
10340 events: These might get delayed via `mouse-autoselect-window'
10343 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
10345 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
10346 manipulation of :loaded-from data.
10348 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
10350 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
10351 now a cons (bug#11311).
10353 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
10355 Do not create empty overlays with the evaporate property (Bug#9642).
10356 * buffer.c (Fmove_overlay): Delete an evaporating overlay
10357 if it becomes empty after its bounds are adjusted to fit within
10358 its buffer. Without this fix, in a nonempty buffer (let ((o
10359 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
10360 yields an empty overlay that has the evaporate property, which is
10361 not supposed to happen.
10363 Fix minor GTK3 problems found by static checking.
10364 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

10383 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
10384 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
10385 (__malloc_size_t, __malloc_ptrdiff_t):
10386 Remove. All uses removed, replaced by the definiens if needed,
10387 since we can assume C89 or better now.

10573 (r_alloc_size_in_use, r_alloc_freeze, r_alloc_thaw): Remove; unused.
10574 (r_alloc_sbrk): Now static.
10576 Improve ralloc.c interface checking.
10577 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html

10606 Remove definition of GC_MARK_STACK, since the default now works.
10607 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
10608 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
10609 no longer the default.
10610 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
10612 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

10637 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
10638 against is gone. It's better to use vfork now so that when Cygwin
10639 gains a new, working vfork, we use it automatically (bug#10398).
10641 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

10656 (force_quit_count): New var.
10657 (handle_interrupt): Use it.
10659 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
10661 * w32.c (w32_delayed_load): Record the full path of the library
10662 being loaded (bug#10424).
10664 2012-04-09 Glenn Morris <rgm@gnu.org>
10666 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
10667 not just in the obarray, before snarfing them. (Bug#11036)
10669 * Makefile.in ($(leimdir)/leim-list.el):
10670 Pass EMACS rather than BUILT_EMACS.
10672 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
10674 * process.c (make_process):
10675 * process.h: Add integer `gnutls_handshakes_tried' member to
10678 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
10679 Add convenience `GNUTLS_LOG2i' macro.
10681 * gnutls.c (gnutls_log_function2i): Convenience log function.
10682 (emacs_gnutls_read): Use new log functions,
10683 `gnutls_handshakes_tried' process member, and
10684 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
10685 attempts per process (connection).
10687 2012-04-09 Chong Yidong <cyd@gnu.org>
10689 * eval.c (Fuser_variable_p, user_variable_p_eh)
10690 (lisp_indirect_variable): Functions deleted.
10691 (Fdefvar): Caller changed.
10693 * callint.c (Finteractive, Fcall_interactively):
10694 * minibuf.c (Fread_variable): Callers changed.
10696 2012-04-09 Eli Zaretskii <eliz@gnu.org>
10698 * xdisp.c (set_cursor_from_row): If the display string appears in
10699 the buffer at position that is closer to point than the position
10700 after the display string, display the cursor on the first glyph of
10701 the display string. Fixes cursor display when a 'display' text
10702 property immediately follows invisible text. (Bug#11094)
10704 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
10706 composite.c: use 'double' consistently
10707 * composite.c (get_composition_id): Use 'double' consistently
10708 instead of converting 'float' to 'double' and vice versa; this is
10709 easier to understand and avoids a GCC warning.
10711 2012-04-09 Glenn Morris <rgm@gnu.org>
10713 * Makefile.in: Generate leim-list with bootstrap-emacs, in
10714 preparation for dumping it with emacs. (Bug#4789)
10715 (leimdir): New variable.
10716 ($(leimdir)/leim-list.el): New rule.
10717 (emacs$(EXEEXT)): Depend on leim-list.el.
10719 * buffer.c (Qucs_set_table_for_input): Remove. (Bug#9821)
10720 (Fget_buffer_create): Don't call Qucs_set_table_for_input.
10721 (init_buffer_once, syms_of_buffer): Remove Qucs_set_table_for_input.
10723 2012-04-08 Andreas Schwab <schwab@linux-m68k.org>

10731 Remove unused local variable.
10733 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
10735 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
10736 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
10737 (mark_memory): Mark Lisp_Objects only if pointers might hide in
10738 objects, as mark_maybe_pointer will catch them otherwise.
10739 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
10740 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
10742 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
10744 Fix typo that broke non-Windows builds.
10745 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
10747 2012-04-07 Eli Zaretskii <eliz@gnu.org>
10749 Support building on MS-Windows with libxml2.
10751 * makefile.w32-in (OBJ2): Add xml.$(O).
10752 (GLOBAL_SOURCES): Add xml.c.
10753 ($(BLD)/xml.$(O)): New dependency list.
10755 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
10756 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
10757 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
10758 [!WINDOWSNT]: New macros.
10759 (init_libxml2_functions, libxml2_loaded_p): New functions.
10760 (parse_region): Call fn_xmlCheckVersion instead of using the macro
10761 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
10762 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
10763 Calls xmlCleanupParser only if libxml2 was loaded (or statically
10765 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
10766 Call init_libxml2_functions before calling libxml2 functions.
10767 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
10769 * emacs.c: Don't include libxml/parser.h.
10770 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
10771 xmlCleanupParser directly.
10773 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
10775 2012-04-07 Eli Zaretskii <eliz@gnu.org>
10777 * indent.c (Fvertical_motion): If there is a display string at
10778 point, use it.vpos to compute how many lines to backtrack after
10779 move_it_to point. (Bug#11133)
10781 2012-04-06 Eli Zaretskii <eliz@gnu.org>
10783 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
10784 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
10785 about subtle differences between FETCH_CHAR* and STRING_CHAR*
10786 macros related to unification of CJK characters. For the details,
10787 see the discussion following the message here:
10788 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
10790 2012-04-04 Chong Yidong <cyd@gnu.org>
10792 * keyboard.c (Vdelayed_warnings_list): Doc fix.
10794 2012-04-01 Eli Zaretskii <eliz@gnu.org>
10796 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
10797 instead of alloca. (Bug#11138)
10799 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
10801 * w32menu.c (is_simple_dialog): Properly check lisp types.
10804 2012-03-31 Eli Zaretskii <eliz@gnu.org>
10806 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
10807 position we get to after a call to move_it_to fails the
10808 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
10809 only if we wind up in a string from display property. (Bug#11063)
10811 * window.c (Fdelete_other_windows_internal): Invalidate the row
10812 and column information about mouse highlight, so that redisplay
10813 restores it after reallocating the glyph matrices. (Bug#7464)
10815 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
10816 string comes from a `display' text property, use the buffer
10817 position of that property as if we actually saw that position in
10819 (move_it_by_lines): Remove the assertion that
10820 "it->current_x == 0 && it->hpos == 0" which can be legitimately
10821 violated when there's a before-string at the beginning of a line.
10824 2012-03-30 Eli Zaretskii <eliz@gnu.org>
10826 * xdisp.c (append_space_for_newline): If the default face was
10827 remapped, use the remapped face for the appended newline.
10828 (extend_face_to_end_of_line): Use the remapped default face for
10829 extending the face to the end of the line.
10830 (display_line): Call extend_face_to_end_of_line when the default
10831 face was remapped. (Bug#11068)
10833 2012-03-29 Eli Zaretskii <eliz@gnu.org>
10835 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
10837 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
10839 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
10841 2012-03-27 Glenn Morris <rgm@gnu.org>
10843 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
10846 2012-03-26 Kenichi Handa <handa@m17n.org>
10848 * dispextern.h (struct glyph): Fix previous change. Change the
10849 bit length of glyphless.ch to 25 (Bug#11082).
10851 2012-03-26 Chong Yidong <cyd@gnu.org>
10853 * keyboard.c (Vselection_inhibit_update_commands): New variable.
10854 (command_loop_1): Use it; inhibit selection update for
10855 handle-select-window too (Bug#8996).
10857 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
10859 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
10861 2012-03-25 Kenichi Handa <handa@m17n.org>
10863 * dispextern.h (struct glyph): Change the bit length of
10864 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
10866 2012-03-24 Eli Zaretskii <eliz@gnu.org>
10868 * s/ms-w32.h (tzname): Include time.h before redirecting to
10869 _tzname. Fixes the MSVC build. (Bug#9960)
10871 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
10873 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
10876 * xterm.c (XTread_socket): Only modify handling_signal if
10877 !SYNC_INPUT. (Bug#11080)
10879 2012-03-23 Eli Zaretskii <eliz@gnu.org>
10881 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
10882 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
10883 when fetching a multibyte character consumes more bytes than
10884 CHAR_BYTES returns, due to unification of CJK characters in
10885 string_char. (Bug#11073)
10887 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
10889 * process.c (wait_reading_process_output): Handle pty disconnect
10890 by refraining from sending oneself a SIGCHLD (bug#10933).
10892 2012-03-22 Chong Yidong <cyd@gnu.org>
10894 * dispextern.h (struct it): New member string_from_prefix_prop_p.
10896 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
10897 Mark string as coming from a prefix property.
10898 (handle_face_prop): Use default face for prefix strings (Bug#4281).
10899 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
10901 2012-03-21 Chong Yidong <cyd@gnu.org>
10903 * xfaces.c (Vface_remapping_alist): Doc fix.
10905 2012-03-20 Eli Zaretskii <eliz@gnu.org>
10907 * w32proc.c (Fw32_set_console_codepage)
10908 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
10911 2012-03-20 Chong Yidong <cyd@gnu.org>
10913 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
10914 to reflect default non-nil value of redisplay-dont-pause.
10916 2012-03-19 Kenichi Handa <handa@m17n.org>
10918 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
10919 it fit in a valid range (Bug#11003).
10921 2012-03-18 Eli Zaretskii <eliz@gnu.org>
10923 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
10924 that is not from display property, accept the row as a "cursor
10925 row" if one of the string's character has a non-nil `cursor'
10926 property. Fixes cursor positioning when there are newlines in
10927 overlay strings, e.g. in icomplete.el. (Bug#11035)
10929 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
10931 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
10933 2012-03-12 Chong Yidong <cyd@gnu.org>
10935 * eval.c (inhibit_lisp_code): Rename from
10936 inhibit_window_configuration_change_hook; move from window.c.
10938 * xfns.c (unwind_create_frame_1, Fx_create_frame):
10939 * window.c (run_window_configuration_change_hook)
10940 (syms_of_window): Callers changed.
10942 2012-03-11 Chong Yidong <cyd@gnu.org>
10944 * keymap.c (Fkey_description): Doc fix (Bug#9700).
10946 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
10948 2012-03-10 Chong Yidong <cyd@gnu.org>
10950 * frame.c (other_visible_frames): Don't assume the selected frame
10951 is visible (Bug#10955).
10953 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
10955 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
10957 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
10959 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
10960 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
10963 2012-03-03 Glenn Morris <rgm@gnu.org>
10965 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
10967 2012-03-02 Eli Zaretskii <eliz@gnu.org>
10969 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
10970 position past the first glyph_row that ends at ZV. (Bug#10902)
10971 (redisplay_window, next_element_from_string): Fix typos in
10973 (redisplay_window): Pass to move_it_vertically the margin in
10974 pixels, not in screen lines.
10976 2012-03-02 Glenn Morris <rgm@gnu.org>
10978 * buffer.c (buffer-list-update-hook): Doc fix.
10980 2012-02-29 Eli Zaretskii <eliz@gnu.org>
10982 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
10983 push_it before setting up the iterator for the first overlay
10984 string, even if we have an empty string loaded.
10985 (next_overlay_string): If there's an empty string on the iterator
10986 stack, pop the stack. (Bug#10903)
10988 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
10990 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
10991 Suggested by Stefan Monnier in
10992 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
10993 * alloc.c (widen_to_Lisp_Object): New static function.
10994 (mark_memory): Also mark Lisp_Objects by fetching pointer words
10995 and widening them to Lisp_Objects. This would work even if
10996 USE_LSB_TAG is defined and wide integers are used, which might
10997 happen in a future version of Emacs.
10999 2012-02-25 Chong Yidong <cyd@gnu.org>
11001 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
11004 * xselect.c (Fx_selection_exists_p): Doc fix.
11005 (x_clipboard_manager_save_all): Print an informative message
11006 before saving to clipboard manager.
11008 2012-02-24 Chong Yidong <cyd@gnu.org>
11010 * keyboard.c (process_special_events): Handle all X selection
11011 requests in kbd_buffer, not just the next one (Bug#8869).
11013 2012-02-23 Chong Yidong <cyd@gnu.org>
11015 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
11016 call when setting menu-bar-lines and tool-bar-lines parameters.
11017 (unwind_create_frame_1): New helper function.
11019 * window.c (inhibit_window_configuration_change_hook): New var.
11020 (run_window_configuration_change_hook): Obey it.
11021 (syms_of_window): Initialize it.
11023 2012-02-22 Chong Yidong <cyd@gnu.org>
11025 * xterm.c (x_draw_image_relief): Add missing type check for
11026 Vtool_bar_button_margin (Bug#10743).
11028 2012-02-21 Chong Yidong <cyd@gnu.org>
11030 * fileio.c (Vfile_name_handler_alist): Doc fix.
11032 * buffer.c (Fget_file_buffer): Protect against invalid file
11033 handler return value.
11035 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
11037 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
11038 when computing $valmask.
11040 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
11041 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
11042 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
11043 It's useless in that case, and it can cause problems on hosts
11044 that allocate halves of EMACS_INT values separately.
11045 Reported by Dan Horák. Diagnosed by Andreas Schwab in
11046 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
11047 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
11048 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
11049 it avoids undefined behavior on hosts where shifting right by more
11050 than the word width has undefined behavior.
11052 2012-02-19 Chong Yidong <cyd@gnu.org>
11054 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
11055 (Funhandled_file_name_directory, Ffile_name_as_directory)
11056 (Fdirectory_file_name, Fexpand_file_name)
11057 (Fsubstitute_in_file_name): Protect against invalid file handler
11058 return values (Bug#10845).
11060 2012-02-18 Eli Zaretskii <eliz@gnu.org>
11062 * .gdbinit (pitx): Fix incorrect references to fields of the
11065 2012-02-17 Chong Yidong <cyd@gnu.org>

11069 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
11071 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
11072 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
11074 2012-02-15 Chong Yidong <cyd@gnu.org>
11076 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
11077 marked as special. Also, starting docstrings with * is obsolete.
11079 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
11081 * gnutls.c (emacs_gnutls_write): Fix last change.
11083 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>
11085 * gnutls.c (emacs_gnutls_write): Set errno appropriately for

11090 * keymap.c (Fsingle_key_description): Handle char ranges.
11092 2012-02-12 Chong Yidong <cyd@gnu.org>
11094 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
11095 as that creates a dangerous corner case.
11097 * window.c (Fdelete_window_internal): Invalidate the mouse
11098 highlight (Bug#9904).
11100 2012-02-12 Glenn Morris <rgm@gnu.org>
11102 * xselect.c (Fx_own_selection_internal)
11103 (Fx_get_selection_internal, Fx_disown_selection_internal)
11104 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
11105 * nsselect.m (Fx_own_selection_internal)
11106 (Fx_disown_selection_internal, Fx_selection_exists_p)
11107 (Fx_selection_owner_p, Fx_get_selection_internal):
11108 Sync docs and argument specs with the xselect.c versions.
11110 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
11112 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.

11660 2011-12-01 Andreas Schwab <schwab@linux-m68k.org>
11662 * keyboard.c (interrupt_signal): Don't call kill-emacs when

11667 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
11668 verifies glyph row's hash code--we have just reallocated the
11669 glyphs, so their contents can be complete garbage. (Bug#10164)

11715 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
11716 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in
11717 this macro definition.

11832 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
11833 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
11834 is set, removing the need for VIRT_ADDRESS_VARIES.
11835 (PURE_P): Use a more-efficient implementation that needs just one
11836 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
11837 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
11838 to 4 (xorl, subq, cmpq, setbe).
11839 * alloc.c (pure): Always extern now, since that's the

11842 consistency with the new puresize.h.
11843 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
11844 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

11850 (erase_phys_cursor, update_window_cursor, show_mouse_face)
11851 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
11852 behave as if the cursor position were at the window margin.
11854 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
11855 and the cursor position is out of bounds, behave as if the cursor
11856 position were at the window margin. (Bug#10075)
11858 2011-11-18 Chong Yidong <cyd@gnu.org>
11860 * window.c (Fwindow_combination_limit): Make first argument

11879 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
11881 * xdisp.c (row_hash): New function, body extracted from
11882 compute_line_metrics.
11883 (compute_line_metrics): Call row_hash, instead of computing the
11886 * dispnew.c (verify_row_hash): Call row_hash for computing the
11887 hash code of a row, instead of duplicating code from xdisp.c.
11889 * dispextern.h (row_hash): Add prototype.
11891 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
11893 * frame.c (delete_frame): Don't delete the terminal when the last

11929 * xdisp.c (display_line): Move the call to
11930 highlight_trailing_whitespace before the call to
11931 compute_line_metrics, since the latter needs to see the final
11932 faces of all the glyphs to compute ROW's hash value.

11942 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
11943 with user-defined heap size. Bump the default size of the temacs

11947 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
11948 current_matrix and desired_matrix. (Bug#9990)
11949 (verify_row_hash) [XASSERTS]: New function.

11996 Avoid some portability problems by eschewing 'extern inline' functions.
11997 The trivial performance wins aren't worth the portability hassles; see
11998 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
12000 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

12066 * xmenu.c (cleanup_widget_value_tree): New function.
12067 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
12068 calling free_menubar_widget_value_tree directly (Bug#9830).
12070 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
12072 Fix some portability problems with 'inline'.
12073 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
12074 (window_box_width, window_box_left, window_box_left_offset)
12075 (window_box_right, window_box_right_offset): Declare extern.
12076 Otherwise, these inline functions do not conform to C99 and
12077 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
12078 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
12079 * intervals.c (adjust_intervals_for_insertion)
12080 (adjust_intervals_for_deletion): Now extern, because otherwise the
12081 extern inline functions 'offset_intervals' couldn't refer to it.
12082 (static_offset_intervals): Remove.
12083 (offset_intervals): Rewrite using the old contents of
12084 static_offset_intervals. The old version didn't conform to C99
12085 because an extern inline function contained a reference to an
12086 identifier with static linkage.
12088 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
12090 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

12108 (Fwindow_vscroll): Doc fix.
12109 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
12110 argument, since it makes no sense to pass a live window and for
12111 consistency with window-child.

12152 official. Move initialization of image_cache_refcount and
12153 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

12193 previous/next-single-property-change returns nil, treat that as
12194 the beginning or the end of the buffer. (Bug#9955)
12196 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
12198 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or

12230 2011-10-30 Eli Zaretskii <eliz@gnu.org>
12232 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
12233 past the beginning of the current glyph matrix.
12235 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
12237 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.

12321 (w32font_open_internal, compute_metrics):
12322 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
12323 instead of calling the "wide" APIs directly.
12325 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
12327 * w32.h (syms_of_w32font): Add prototype.
12329 2011-10-27 Juanma Barranquero <lekktu@gmail.com>

12333 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
12334 (Fmove_to_window_line): Doc fix.
12336 2011-10-27 Chong Yidong <cyd@gnu.org>
12338 * process.c (make_process): Set gnutls_state to NULL.
12340 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
12341 non-NULL, regardless of GNUTLS_INITSTAGE.
12342 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal

12390 (bidi_resolve_weak): Don't enter the expensive loop if the current
12391 position is before next_en_pos. Record the bidi type of the first
12392 non-ET, non-BN character we find, in addition to its position.
12393 (bidi_level_of_next_char): Invalidate next_en_type when
12394 next_en_pos is over-stepped.
12396 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
12398 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
12399 * editfns.c: Rewrite current-time-zone so that it invokes
12400 the equivalent of (format-time-string "%Z") to get the time zone name.
12401 This fixes a bug when the time zone name contains characters that
12402 need converting from the system time locale to Emacs internal format.
12403 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
12404 that patch fixed format-time-string to do the conversion, but
12405 I forgot to fix current-time-zone.
12406 (format_time_string): New function, containing most of
12407 what Fformat_time_string used to contain.
12408 (Fformat_time_string): Rewrite in terms of format_time_string.
12409 This doesn't change this function's behavior.
12410 (current-time-zone): Rewrite to use format_time_string.
12411 This fixes the bug reported by Michael Schierl in
12412 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
12413 Jason Rumney's 2007-06-07 change worked around this bug, but
12415 * systime.h (tzname, timezone): Remove no-longer-used declarations.
12417 2011-10-19 Eli Zaretskii <eliz@gnu.org>
12419 * xdisp.c (start_display): If the character at POS is displayed
12420 via a display vector, reset IT->current.dpvec_index to zero.
12421 (try_window_reusing_current_matrix): If a line ends in a display
12422 vector or the next line starts in a display vector, continue
12423 redrawing the window even though the character position of
12424 start_row was reached.
12427 2011-10-18 Chong Yidong <cyd@gnu.org>
12429 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
12430 with nobreak-char-display too.
12432 2011-10-18 Eli Zaretskii <eliz@gnu.org>
12434 Fix part 3 of bug#9771.
12435 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
12436 (bidi_resolve_neutral): Don't enter the expensive loop looking for
12437 non-neutral characters if the current character is a paragraph
12438 separator (a.k.a. Newline). This avoids running the same
12439 expensive loop twice, once when we consume the preceding newline
12440 and the other time when the line actually needs to be displayed.
12441 Avoid the loop when we see neutrals on the base embedding level
12442 following a character whose directionality is the same as the
12443 paragraph's. This avoids running the expensive loop when a line
12444 ends in a long sequence of neutrals, like control characters.
12445 Add assertion against STRONG_AL type. Slightly rearrange code
12446 that determines the type of a neutral given the first non-neutral
12448 (bidi_level_of_next_char): Set next_en_pos to zero when
12449 invalidating its info.
12451 2011-10-17 Eli Zaretskii <eliz@gnu.org>
12453 * xdisp.c (push_display_prop): Determine whether to record string
12454 or buffer position by IT->string, not by IT->method. Allow
12455 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
12456 (move_it_vertically_backward): Don't look for character position
12457 immediately after the newline when in a continuation line.
12460 2011-10-15 Martin Rudalics <rudalics@gmx.at>
12462 * window.c (coordinates_in_window): Rewrite and delabelize
12463 vertical border check. (Bug#5357) (Bug#9618)

12467 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
12468 errors in XSetWindowBorder (bug#9310).
12470 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
12472 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
12473 avoid crash when xmalloc overrun checking is enabled.
12475 2011-10-13 Eli Zaretskii <eliz@gnu.org>
12477 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
12478 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
12479 cursor motion with <left> and <right> arrow keys.
12481 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
12482 some callers set that themselves.
12484 2011-10-12 Eli Zaretskii <eliz@gnu.org>
12486 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
12487 display string and the previous row comes from the same string and
12488 is empty. (Bug#9739) (Bug#9738)
12490 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
12492 * doc.c (get_doc_string): Encode file name (bug#9735).
12494 2011-10-12 Eli Zaretskii <eliz@gnu.org>
12496 * bidi.c (bidi_level_of_next_char):
12497 * xdisp.c (get_visually_first_element): Remove old incorrect
12498 comments regarding the Unicode Line Separator character.
12500 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
12502 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>

12508 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
12510 * xdisp.c (set_cursor_from_row): Simplify conditionals,
12511 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
12513 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
12514 Some packages use them to denote characters with modifiers.
12516 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
12518 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
12519 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
12520 matching a pp-number. Rename parameter var to var1.
12522 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
12524 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
12526 2011-10-08 Glenn Morris <rgm@gnu.org>
12528 * callint.c (Fcall_interactively): Give a more explicit error for the
12529 'c' case with a non-character input. (Bug#8479)
12531 2011-10-08 Eli Zaretskii <eliz@gnu.org>
12533 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
12535 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
12536 lines that are hscrolled on the left.
12538 * dispnew.c (buffer_posn_from_coords): Account for a possible
12539 presence of header-line. (Bug#4426)
12541 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
12543 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
12544 Don't advertise functionality which we discourage or doesn't work.
12546 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
12548 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
12549 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
12550 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
12551 this makes Emacs dump core during garbage collection on rare
12552 occasions. sizeof is obviously inferior to offsetof here, so
12553 stick with offsetof.
12554 (GC_POINTER_ALIGNMENT): New macro.
12555 (mark_memory): Omit 3rd (offset) arg; caller changed.
12556 Don't assume EMACS_INT alignment is the same as pointer alignment.
12558 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
12560 * keyboard.c (read_key_sequence_remapped): New var.
12561 (read_key_sequence): Compute remapping in the right buffer.
12562 (command_loop_1): Use read_key_sequence's remapping directly.
12564 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
12566 * dired.c (file_name_completion): Don't expand file name.
12567 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
12568 before checking file name handler.
12570 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
12571 they've been requested explicitly (bug#9591).
12573 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
12575 * keymap.c (Fsingle_key_description): Use make_specified_string
12576 instead of build_string to build string from push_key_description.
12579 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
12581 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
12582 This fixes a Y2038 bug on 64-bit hosts.
12583 * buffer.c (reset_buffer):
12584 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
12585 (Fclear_buffer_auto_save_failure):
12586 Use 0, not -1, to represent an unset failure time, since time_t
12587 might not be signed.
12589 Remove dependency on glibc malloc internals.
12590 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12591 Move back here from lisp.h, but with their new implementations.
12592 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
12593 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
12594 * charset.c (charset_table_init): New static var.
12595 (syms_of_charset): Use it instead of xmalloc. This removes a
12596 dependency on glibc malloc internals. See Eli Zaretskii's comment in
12597 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
12598 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12599 Move back to alloc.c.
12600 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
12601 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
12603 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
12605 * nsterm.m (windowDidResize): Call x_set_window_size only when
12606 ns_in_resize is true. Otherwise set pixelwidth/height and
12607 call change_frame_size (Bug#9628).
12609 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
12611 Port --enable-checking=all to Fedora 14 x86-64.
12612 * charset.c (syms_of_charset): Also account for glibc malloc's
12613 internal overhead when calculating the initial malloc maximum.
12615 Port --enable-checking=all to Fedora 14 x86.
12616 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12618 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
12619 (overrun_check_realloc, overrun_check_free):
12620 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
12621 That way, xmalloc returns a properly-aligned pointer even if
12622 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
12623 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
12624 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
12625 into account when calculating the initial malloc maximum.
12626 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12627 Move here from alloc.c, so that charset.c can use it too.
12628 Properly align; the old code wasn't right for common 32-bit hosts
12629 when configured with --enable-checking=all.
12630 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
12631 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
12633 2011-09-29 Eli Zaretskii <eliz@gnu.org>
12635 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
12638 2011-09-28 Eli Zaretskii <eliz@gnu.org>
12640 * xdisp.c (compute_display_string_end): If there's no display
12641 string at CHARPOS, return -1.
12643 * bidi.c (bidi_fetch_char): When compute_display_string_end
12644 returns a negative value, treat the character as a normal
12645 character not covered by a display string. (Bug#9624)
12647 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
12649 * lread.c (Fread_from_string): Fix typo in docstring.
12651 2011-09-27 Eli Zaretskii <eliz@gnu.org>
12653 * xdisp.c (handle_invisible_prop): If invisible text ends on a
12654 newline, reseat the iterator instead of bidi-iterating there one
12655 character at a time. (Bug#9610)
12656 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
12657 TO_CHARPOS if the bidi iterator is at base embedding level.
12659 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
12661 * lread.c (readevalloop): Use correct code for NBSP.
12662 (read1): Likewise. (Bug#9608)
12664 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
12666 * dbusbind.c (Fdbus_register_signal): When service is not
12667 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
12669 2011-09-25 Glenn Morris <rgm@gnu.org>
12671 * buffer.c (truncate-lines): Doc fix.
12673 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
12675 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
12676 (Fset_window_next_buffers): Doc fix.
12678 2011-09-24 Glenn Morris <rgm@gnu.org>
12680 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
12682 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
12684 Fix minor problems found by static checking.
12685 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
12686 * indent.c (Fvertical_motion): Fix == vs = typo.
12688 2011-09-24 Eli Zaretskii <eliz@gnu.org>
12690 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
12691 Default value is now t. Doc fix.
12693 * indent.c (Fvertical_motion): Compute and apply the overshoot
12694 logic when moving up, not only when moving down. Fix the
12695 confusing name and values of the it_overshoot_expected variable;
12696 logic changes accordingly. (Bug#9254) (Bug#9549)
12698 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
12699 CHARPOS is covered by a display string which includes newlines.
12700 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
12701 is covered by a display string with embedded newlines.
12703 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
12705 * dbusbind.c (Fdbus_register_signal): Add match rule to
12706 Vdbus_registered_objects_table. (Bug#9581)
12707 (Fdbus_register_method, Vdbus_registered_objects_table):
12710 2011-09-24 Jim Meyering <meyering@redhat.com>
12712 do not ignore write error for any output size
12713 The previous change was incomplete.
12714 While it makes emacs --batch detect the vast majority of stdout
12715 write failures, errors were still ignored whenever the output size is
12716 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
12717 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
12718 && echo FAIL: ignored write error
12719 FAIL: ignored write error
12720 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
12721 && echo FAIL: ignored write error
12722 FAIL: ignored write error
12723 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
12725 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
12727 * emacs.c (Fkill_emacs): In noninteractive mode exit
12728 non-successfully if a write error occurred on stdout. (Bug#9574)
12730 2011-09-21 Eli Zaretskii <eliz@gnu.org>
12732 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
12735 * dispextern.h (struct it): Update the comment documenting what
12738 2011-09-20 Eli Zaretskii <eliz@gnu.org>
12740 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
12741 a display string, extend search for cursor position to end of row.
12742 (find_row_edges): If the row ends in a newline from a display
12743 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
12744 Handle the case of a display string with multiple newlines.
12745 (Fcurrent_bidi_paragraph_direction): Fix search for previous
12746 non-empty line. Fixes confusing cursor motion with arrow keys at
12747 the beginning of a line that starts with whitespace.
12749 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
12751 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
12754 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
12756 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
12757 boolean (Bug#9154).
12759 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12761 * xdisp.c (display_line): Record maximum and minimum buffer
12762 positions even if no glyphs were produced (e.g., by a zero-width
12763 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
12764 buffer positions that will be removed from the glyph row because
12766 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
12767 column is beyond frame width: don't subtract 1 "pixel" when
12768 computing width of the stretch.
12769 (reseat_at_next_visible_line_start): Undo the change made on
12770 2011-09-17 that saved paragraph information and restored it after
12771 the call to `reseat'. (Bug#9545)
12773 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12775 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
12776 and turn window cursor on if cleared (Bug#9415).
12778 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
12780 * search.c (boyer_moore): Take unibyte characters from pattern
12781 literally. (Bug#9458)
12783 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12785 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
12787 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
12789 Fix minor problem found by static checking.
12790 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
12791 initialized, to pacify gcc -Wuninitialized.
12793 * fileio.c: Report proper errno when syscall falls.
12794 (Finsert_file_contents): Save and restore errno,
12795 so that report_file_error outputs the correct diagnostic.
12796 (Fwrite_region) [CLASH_DETECTION]: Likewise.
12798 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12800 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
12802 2011-09-17 Eli Zaretskii <eliz@gnu.org>
12804 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
12805 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
12807 2011-09-17 Eli Zaretskii <eliz@gnu.org>
12809 * xdisp.c (reseat_at_next_visible_line_start): Keep information
12810 about the current paragraph and restore it after the call to reseat.
12812 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
12813 (bidi_find_paragraph_start): Search back for paragraph beginning
12814 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
12815 (bidi_move_to_visually_next): Only trigger paragraph-related
12816 computations when the last character is a newline or at EOB, not
12817 just any NEUTRAL_B. (Bug#9470)
12819 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
12820 truncated lines if point is covered by a display string. (Bug#9524)
12822 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
12824 * xselect.c: Relax test for outgoing X longs (Bug#9498).
12825 (cons_to_x_long): New function.
12826 (lisp_data_to_selection_data): Use it. Correct the test for
12827 short-versus-long data; it was negated. Break out of vector
12828 loop, for efficiency, when a long datum is discovered.
12830 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
12832 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
12834 2011-09-16 Eli Zaretskii <eliz@gnu.org>
12836 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
12837 GCC PR/17406) by declaring this function with external scope.
12839 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
12841 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
12842 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
12844 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
12846 * editfns.c (Fformat): Correctly handle text properties on "%%".
12848 2011-09-15 Eli Zaretskii <eliz@gnu.org>
12850 * xterm.c (x_draw_composite_glyph_string_foreground):
12851 * w32term.c (x_draw_composite_glyph_string_foreground):
12852 * term.c (encode_terminal_code):
12853 * composite.c (composition_update_it, get_composition_id):
12854 * xdisp.c (get_next_display_element)
12855 (fill_composite_glyph_string): Add comments about special meaning
12856 of TAB characters in a composition.
12858 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
12860 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
12861 This occurs when processing a multibyte format.
12862 Problem reported by Wolfgang Jenker.
12864 2011-09-15 Johan Bockgård <bojohan@gnu.org>
12866 * xdisp.c (try_cursor_movement): Only check for exact match if
12867 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
12869 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
12871 Remove unused external symbols.
12872 * dispextern.h (calc_pixel_width_or_height): Remove decl.
12873 * xdisp.c (calc_pixel_width_or_height): Now static.
12874 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
12875 * indent.c (check_display_width):
12876 * w32term.c: Fix comment to match code.
12877 * xterm.c, xterm.h (x_catching_errors): Remove.
12879 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
12881 * xselect.c: Use signed conversions more consistently (Bug#9498).
12882 (selection_data_to_lisp_data): Assume incoming selection data are
12883 signed integers, not unsigned. This is to be consistent with
12884 outgoing selection data, which was modified to use signed integers
12885 in as part of the fix to Bug#9196 in response to Jan D.'s comment
12886 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
12887 expects long, not unsigned long.
12889 2011-09-14 Eli Zaretskii <eliz@gnu.org>
12891 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
12892 computation of loop end. Reported by Johan Bockgård
12895 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
12897 * frame.c (Fother_visible_frames_p): Function deleted.
12899 2011-09-12 Eli Zaretskii <eliz@gnu.org>
12901 * indent.c (compute_motion): Process display vector front to back
12902 rather than the other way around. (Bug#2496)
12904 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
12906 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
12908 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
12910 * minibuf.c (Fread_from_minibuffer): Doc fix.
12912 2011-09-11 Eli Zaretskii <eliz@gnu.org>
12914 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
12915 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
12917 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
12919 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
12920 value for non-existent files.
12922 2011-09-11 Eli Zaretskii <eliz@gnu.org>
12924 * fileio.c (Finsert_file_contents): If the file cannot be opened,
12925 set its "size" to -1. This will set the modtime_size field of
12926 the corresponding buffer to -1, which is what
12927 verify-visited-file-modtime expects for files that do not exist.
12930 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
12932 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
12934 * lisp.h: ... from here. push_key_description is no longer
12935 defined in keyboard.c, so its declaration should not be in
12936 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
12937 logically belongs with push_key_description.
12939 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
12941 * buffer.h: Include <sys/types.h> instead of <time.h>.
12942 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
12943 Problem reported by Herbert J. Skuhra.
12945 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
12947 * xml.c (parse_region): Make the parsing work for
12948 non-comment-starting XML files again (bug#9144).
12950 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
12952 * image.c (gif_load): Fix calculation of bottom and right corner.
12955 2011-09-10 Eli Zaretskii <eliz@gnu.org>
12957 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
12958 redisplay in small windows.
12960 2011-09-09 Eli Zaretskii <eliz@gnu.org>
12962 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
12964 2011-09-08 Martin Rudalics <rudalics@gmx.at>
12966 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
12967 Operate on live windows only.
12969 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
12971 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
12973 2011-09-07 Eli Zaretskii <eliz@gnu.org>
12975 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
12976 only under bidi iteration.
12978 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
12980 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
12982 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12984 isnan: Fix porting problem to Solaris 10 with bundled gcc.
12985 Without this fix, the command to link temacs failed due to an
12986 undefined symbol __builtin_isnan. This is because
12987 /usr/include/iso/math_c99.h #defines isnan(x) to
12988 __builtin_isnan(x), but the bundled gcc, which identifies itself
12989 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
12991 * floatfns.c (isnan): #undef, and then #define to a clone of
12993 (Fisnan): Always define, since it's always available now.
12994 (syms_of_floatfns): Always define isnan at the Lisp level.
12996 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12998 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
13000 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13002 * fileio.c: Fix bugs with large file offsets (Bug#9428).
13003 The previous code assumed that file offsets (off_t values) fit in
13004 EMACS_INT variables, which is not true on typical 32-bit hosts.
13005 The code messed up by falsely reporting buffer overflow in cases
13006 such as (insert-file-contents "big" nil 1 2) into an empty buffer
13007 when "big" contains more than 2**29 bytes, even though this
13008 inserts just one byte and does not overflow the buffer.
13009 (Finsert_file_contents): Store file offsets as off_t
13010 values, not as EMACS_INT values. Check for overflow when
13011 converting between EMACS_INT and off_t. When checking for
13012 buffer overflow or for overlap, take the offsets into account.
13013 Don't use EMACS_INT for small values where int suffices.
13014 When checking for overlap, fix a typo: ZV was used where
13015 ZV_BYTE was intended.
13016 (Fwrite_region): Don't assume off_t fits into 'long'.
13017 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
13019 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
13021 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
13023 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13025 sprintf-related integer and memory overflow issues (Bug#9412).
13027 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
13028 (esprintf, exprintf, evxprintf): New functions.
13029 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
13030 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
13031 (modify_event_symbol): Do not assume that the length of
13032 name_alist_or_stem is safe to alloca and fits in int.
13033 (Fexecute_extended_command): Likewise for function name and binding.
13034 (Frecursion_depth): Wrap around reliably on integer overflow.
13035 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
13036 since some callers pass EMACS_INT values.
13037 (Fsingle_key_description): Don't crash if symbol name contains more
13038 than MAX_ALLOCA bytes.
13039 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
13040 (get_minibuffer): Arg is now EMACS_INT, not int.
13041 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
13042 (esprintf, exprintf, evxprintf): New decls.
13043 * window.h (command_loop_level, minibuf_level): Reflect API changes.
13045 * dbusbind.c (signature_cat): New function.
13046 (xd_signature, Fdbus_register_signal):
13047 Do not overrun buffer; instead, report string overflow.
13049 * dispnew.c (add_window_display_history): Don't overrun buffer.
13050 Truncate instead; this is OK since it's just a log.
13052 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
13053 even if the time zone offset is outlandishly large.
13054 Don't mishandle offset == INT_MIN.
13056 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
13057 when creating daemon; the previous buffer-overflow check was incorrect.
13059 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
13060 which has the guts of the old verror function.
13062 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
13063 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
13065 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
13066 (font_unparse_xlfd): Don't blindly alloca long strings.
13067 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
13068 fits in int, when using sprintf. Use single snprintf to count
13069 length of string rather than counting it via multiple sprintfs;
13070 that's simpler and more reliable.
13071 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
13072 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
13073 sprintf, in case result does not fit in int.
13075 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
13076 (fontset_from_font): Print it.
13078 * frame.c (tty_frame_count): Now printmax_t, not int.
13079 (make_terminal_frame, set_term_frame_name): Print it.
13080 (x_report_frame_params): In X, window IDs are unsigned long,
13081 not signed long, so print them as unsigned.
13082 (validate_x_resource_name): Check for implausibly long names,
13083 and don't assume name length fits in 'int'.
13084 (x_get_resource_string): Don't blindly alloca invocation name;
13085 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
13088 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
13089 (xg_check_special_colors, xg_set_geometry):
13090 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
13092 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
13093 Use esprintf, not sprintf, in case result does not fit in int.
13095 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13096 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
13097 it as a large positive number.
13098 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
13099 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13101 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
13102 in case result does not fit in int.
13104 * print.c (float_to_string): Detect width overflow more reliably.
13105 (print_object): Make sprintf buffer a bit bigger, to avoid potential
13106 buffer overrun. Don't assume list length fits in 'int'. Treat
13107 print length of 0 as 0, not as infinity; to be consistent with other
13108 uses of print length in this function. Don't overflow print length
13109 index. Don't assume hash table size fits in 'long', or that
13110 vectorlike size fits in 'unsigned long'.
13112 * process.c (make_process): Use printmax_t, not int, to format
13113 process-name gensyms.
13115 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
13117 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
13118 to avoid potential buffer overrun.
13120 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
13121 if X resource line is longer than 512 bytes.
13123 * xfns.c (x_window): Make sprintf buffer a bit bigger
13124 to avoid potential buffer overrun.
13126 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
13128 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
13130 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13132 Integer overflow fixes for scrolling, etc.
13133 Without these, Emacs silently mishandles large integers sometimes.
13134 For example, "C-u 4294967297 M-x recenter" was treated as if
13135 it were "C-u 1 M-x recenter" on a typical 64-bit host.
13137 * xdisp.c (try_window_id): Check Emacs fixnum range before
13138 converting to 'int'.
13140 * window.c (window_scroll_line_based, Frecenter):
13141 Check that an Emacs fixnum is in range before assigning it to 'int'.
13142 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
13143 values converted from Emacs fixnums.
13144 (Frecenter): Don't wrap around a line count if it is out of 'int'
13145 range; instead, treat it as an extreme value.
13146 (Fset_window_configuration, compare_window_configurations):
13147 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
13149 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
13150 that can exceed INT_MAX. Check that EMACS_INT value is in range
13151 before assigning it to the (possibly-narrower) index.
13152 (match_limit): Don't assume that a fixnum can fit in 'int'.
13154 * print.c (print_object): Use ptrdiff_t, not int, for index that can
13157 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
13158 (Fvertical_motion): Don't wrap around LINES values that don't fit
13159 in 'int'. Instead, treat them as extreme values. This is good
13160 enough for windows, which can't have more than INT_MAX lines anyway.
13162 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
13164 * Require libxml/parser.h to avoid compilation warning.
13166 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
13168 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
13169 since this reportedly can destroy thread storage.
13171 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
13173 * syntax.c (find_defun_start): Update all cache variables if
13174 exiting early (Bug#9401).
13176 2011-08-30 Eli Zaretskii <eliz@gnu.org>
13178 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
13180 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
13181 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
13182 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
13184 * term.c (tty_append_glyph): New function.
13185 (produce_stretch_glyph): Static function and its prototype deleted.
13187 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
13190 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
13192 * image.c (parse_image_spec): Check for nonnegative, not for positive,
13193 when checking :margin (Bug#9390).
13194 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
13195 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
13196 so that the name doesn't mislead. All uses changed.
13198 2011-08-28 Johan Bockgård <bojohan@gnu.org>
13200 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
13203 2011-08-27 Eli Zaretskii <eliz@gnu.org>
13205 * xdisp.c (move_it_to): Don't bail out early when reaching
13206 position beyond to_charpos, if we are scanning backwards.
13207 (move_it_vertically_backward): When DY == 0, make sure we get to
13208 the first character in the line after the newline.
13210 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
13212 * ccl.c: Improve and simplify overflow checking (Bug#9196).
13213 (ccl_driver): Do not generate an out-of-range pointer.
13214 (Fccl_execute_on_string): Remove unnecessary check for
13215 integer overflow, noted by Stefan Monnier in
13216 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
13217 Remove a FIXME that didn't need fixing.
13218 Simplify the newly-introduced buffer reallocation code.
13220 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
13222 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
13224 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
13226 Integer and memory overflow issues (Bug#9196).
13228 * doc.c (get_doc_string): Rework so that
13229 get_doc_string_buffer_size is the actual buffer size, rather than
13230 being 1 less than the actual buffer size; this makes xpalloc more
13233 * image.c (x_allocate_bitmap_record, cache_image):
13234 * xselect.c (Fx_register_dnd_atom):
13235 Simplify previous changes by using xpalloc.
13237 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
13238 since either will do and ptrdiff_t is convenient with xpalloc.
13240 * charset.c (charset_table_size)
13241 (struct charset_sort_data.priority): Now ptrdiff_t.
13242 (charset_compare): Don't overflow if priorities differ greatly.
13243 (Fsort_charsets): Don't assume list length fits in int.
13244 Check for size-calculation overflow when allocating sort data.
13245 (syms_of_charset): Allocate an initial charset table that is
13246 just under 64 KiB, to avoid problems with glibc malloc and mmap.
13248 * cmds.c (internal_self_insert): Check for size-calculation overflow.
13250 * composite.h (struct composition.glyph_len): Now int, not unsigned.
13251 The actual value is always <= INT_MAX, and leaving it unsigned made
13252 overflow checking harder.
13254 * dispextern.h (struct glyph_matrix.rows_allocated)
13255 (struct face_cache.size): Now ptrdiff_t, for convenience in use
13256 with xpalloc. The values are still always <= INT_MAX.
13258 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
13260 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
13261 (SAFE_NALLOCA): New macro.
13263 * region-cache.c (struct boundary.pos, find_cache_boundary)
13264 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
13265 (set_cache_region, invalidate_region_cache)
13266 (revalidate_region_cache, know_region_cache, region_cache_forward)
13267 (region_cache_backward, pp_cache):
13268 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
13269 so that ptrdiff_t * can be passed to xpalloc.
13270 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
13271 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
13272 (pp_cache): Don't assume cache_len fits in int.
13273 * region-cache.h: Adjust extern decls to match.
13275 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
13276 EMACS_INT, since either will do, for xpalloc.
13278 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
13279 (xnmalloc, xnrealloc, xpalloc): New functions.
13281 * bidi.c (bidi_shelve_header_size): New constant.
13282 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
13283 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
13285 * bidi.c (bidi_cache_shrink):
13286 * buffer.c (overlays_at, overlays_in, record_overlay_string)
13288 Don't update size of array until after memory allocation succeeds,
13289 because xmalloc/xrealloc may not return.
13290 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
13291 now that we have proper integer overflow checking.
13292 (record_overlay_string, overlay_strings): Catch overflows when
13293 calculating size of overlay_str_buf.
13295 * callproc.c (Fcall_process): Check for size overflow when
13296 calculating size of args2.
13297 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
13298 Normally we prefer signed values, but sticking with ptrdiff_t would
13299 require adding more-complicated checks.
13301 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
13302 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
13303 Redo buffer-overflow calculations to avoid integer overflow.
13304 Add a FIXME comment where memory seems to be over-allocated.
13306 * character.c (Fstring): Check for size-calculation overflow.
13308 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
13309 unnecessary integer overflow. Check for size overflow.
13310 (encode_coding_object): Don't update size until xmalloc succeeds.
13312 * composite.c (get_composition_id): Check for overflow in glyph
13313 length calculations.
13315 Integer and memory overflow fixes for display code.
13316 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
13317 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
13318 (scrolling_window): Check for overflow in size calculations.
13319 (line_draw_cost, realloc_glyph_pool, add_row_entry):
13320 Don't assume glyph table len fits in int.
13321 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
13322 (row_table_size): Now ptrdiff_t, not int.
13323 (scrolling_window): Avoid overflow in size calculations.
13324 Don't update size until allocation succeeds.
13325 * fns.c (concat): Check for overflow in size calculations.
13326 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
13327 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
13328 (NEXT_ALMOST_PRIME_LIMIT): New constant.
13330 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
13331 (get_doc_string): Check for size calculation overflow.
13332 Don't update size until allocation succeeds.
13333 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
13334 EMACS_INT, where ptrdiff_t will do.
13335 (Fsubstitute_command_keys): Check for string overflow.
13337 * editfns.c (set_time_zone_rule): Don't assume environment length
13339 (message_length): Now ptrdiff_t, not int.
13340 (Fmessage_box): Don't update size until allocation succeeds.
13341 Don't assume message length fits in int.
13342 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
13344 * emacs.c (main): Do not reallocate argv, since there is a null at
13345 the end that can be overwritten, and this way there's no need to
13346 worry about size-calculation overflow.
13347 (sort_args): Check for size-calculation overflow.
13349 * eval.c (init_eval_once, grow_specpdl): Don't update size until
13351 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
13353 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
13354 (x_set_scroll_bar_width, x_figure_window_size):
13355 Check for integer overflow.
13356 (x_set_alpha): Do not assume XINT fits in int.
13358 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
13359 This is for the members text_lines, text_cols, total_lines, total_cols,
13360 where the system imposes an 'int' limit.
13362 * fringe.c (Fdefine_fringe_bitmap):
13363 Don't update size until alloc works.
13365 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
13366 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
13368 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
13369 Check for size-calculation overflow.
13370 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
13371 do, as we prefer signed integers.
13372 (id_to_widget.max_size, id_to_widget.used)
13373 (xg_store_widget_in_map, xg_remove_widget_from_map)
13374 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
13375 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
13376 Use and return ptrdiff_t, not int.
13377 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
13378 * gtkutil.h: Change prototypes to match the above.
13380 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
13381 are duplicate now that they've been promoted to lisp.h.
13382 (x_allocate_bitmap_record, x_alloc_image_color)
13383 (make_image_cache, cache_image, xpm_load):
13384 Don't update size until alloc is done.
13385 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
13387 Check for size calculation overflow.
13388 (ct_colors_allocated_max): New constant.
13389 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
13392 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
13393 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
13394 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
13395 Use ptrdiff_t, not int, to count maps.
13396 (read_char_minibuf_menu_prompt): Check for overflow in size
13397 calculations. Don't update size until allocation succeeds.
13398 Redo calculations to avoid overflow.
13399 * keyboard.h: Change prototypes to match the above.
13401 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
13403 (current_minor_maps): Check for size calculation overflow.
13404 * keymap.h: Change prototypes to match the above.
13406 * lread.c (read1, init_obarray): Don't update size until alloc done.
13408 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
13409 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
13411 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
13412 Now ptrdiff_t, not int.

13425 (Fset_match_data): Don't assume list lengths fit in 'int'.
13427 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
13428 for command line length. Do not attempt to address one before the
13429 beginning of an array, as that's not portable.
13431 * term.c (max_frame_lines): Remove; unused.

13457 Use ptrdiff_t, not int, for sizes.
13458 (Finternal_make_lisp_face, cache_face):
13459 Check for size calculation overflow.
13460 (cache_face): Treat size calculation overflows as if they were
13461 memory exhaustion (the usual treatment), rather than aborting.
13463 * xfns.c (x_encode_text, x_set_name_internal)
13464 (Fx_change_window_property): Use ptrdiff_t, not int, to count
13465 sizes, since they can exceed INT_MAX in size. Check for size
13466 calculation overflow.
13468 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
13469 (xg_select): Check for size calculation overflow.
13470 Don't update size until alloc done.
13472 * xrdb.c (get_environ_db): Don't assume path length fits in int,
13473 as sprintf is limited to int lengths.
13475 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
13476 (X_LONG_MIN): New macros.
13477 Use them to make the following changes clearer.
13478 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
13479 This change doesn't affect the value now, but it may help remind
13480 future maintainers not to raise the value too much later.
13481 (SELECTION_QUANTUM): Remove, replacing with ...
13482 (selection_quantum): ... new function, which avoids overflow.
13484 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
13485 assumption that selection length fits in 'int'.
13486 (x_reply_selection_request, x_handle_selection_request)
13487 (x_get_window_property, receive_incremental_selection)

13493 Redo calculations to avoid overflow.
13494 (x_reply_selection_request): When sending hint, ceiling it at

13502 Don't store size until memory allocation succeeds.
13503 (x_get_window_property): Plug memory leak on memory exhaustion.
13504 Don't double-block input; malloc is safe here. Don't assume 2**34
13505 - 4 fits in unsigned long. Add an xassert to check
13506 XGetWindowProperty overflow. Be more careful about overflow
13507 calculations, and distinguish size from memory overflow better.
13508 (receive_incremental_selection): When tracing, don't assume
13509 unsigned int is less than INT_MAX.
13510 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
13511 harmful) conversions of unsigned short to int.
13512 (lisp_data_to_selection_data): Don't assume that integers
13513 in the range -65535 through -1 fit in an X unsigned short.
13514 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
13515 result parameters unless successful. Rely on cons_to_unsigned
13516 to report problems with elements; the old code wasn't right anyway.
13517 (x_check_property_data): Check for int overflow; we cannot use
13518 a wider type due to X limits.
13519 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
13521 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.

13551 * lisp.h (hash_lookup, hash_put):
13552 * minibuf.c (Ftest_completion):
13553 Use ptrdiff_t for hash table indexes, not int (which is too
13554 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
13555 32-bit --with-wide-int hosts).
13557 * charset.c (Fdefine_charset_internal): Check for integer overflow.
13558 Add a FIXME comment about memory leaks.
13559 (syms_of_charset): Don't assume xmalloc returns.

13566 with outlandish widths.
13567 * character.h (sanitize_tab_width): Rename from sanitize_width,
13568 now that we have two such functions. All uses changed.

13586 * xterm.c: Don't go over XClientMessageEvent limit.
13587 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
13588 (x_send_scroll_bar_event): Likewise. Check that the size does not
13589 exceed limits imposed by XClientMessageEvent, as well as the usual
13590 ptrdiff_t and size_t limits.
13592 * keyboard.c: Overflow, signedness and related fixes.
13593 (make_lispy_movement): Use same integer type in forward decl
13594 that is used in the definition.
13595 (read_key_sequence, keyremap_step):
13596 Change bufsize argument back to int, undoing my 2011-03-30 change.
13597 We prefer signed types, and int is wide enough here.
13598 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
13599 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
13600 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
13601 length, not size_t. Use ptrdiff_t for index, not int.
13602 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
13603 possibility of integer overflow.
13605 Overflow, signedness and related fixes for images.

13627 (lookup_image): Remove unnecessary tests.
13628 (xbm_image_p): Locals are now of int, not EMACS_INT,
13629 since parse_image_check makes sure they fit into int.
13630 (png_load, gif_load, svg_load_image):
13631 Prefer int to unsigned where either will do.
13632 (tiff_handler): New function, combining the cores of the
13633 old tiff_error_handler and tiff_warning_handler.
13634 This function is rewritten to use vsnprintf and thereby avoid
13635 stack buffer overflows. It uses only the features of vsnprintf
13636 that are common to both POSIX and native Microsoft.
13637 (tiff_error_handler, tiff_warning_handler): Use it.
13638 (tiff_load, gif_load, imagemagick_load_image):
13639 Don't assume :index value fits in 'int'.
13640 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
13641 (imagemagick_load_image): Check that crop parameters fit into
13642 the integer types that MagickCropImage accepts. Don't assume
13643 Vimagemagick_render_type has a nonnegative value. Don't assume
13644 size_t fits in 'long'.
13645 (gs_load): Use printmax_t to print the widest integers possible.

13658 handle_single_display_spec, not just 1 or zero.
13659 (handle_single_display_spec): If the display spec is of the form
13660 `(space ...)', and specifies display in the text area, return 2
13662 (try_cursor_movement): Check for the need to scroll more
13663 accurately, and prefer exact match for point under bidi.
13664 Don't advance `row' beyond the last row of the window.

13682 buffers, return left-to-right.
13683 (set_cursor_from_row): Consider candidate row a win if its glyph
13684 represents a newline and point is on that newline. Fixes cursor
13685 positioning on the newline at EOL of R2L text within L2R
13686 paragraph, and vice versa.
13687 (try_cursor_movement): Check continued rows, in addition to
13688 continuation rows. Fixes unwarranted scroll when point enters a
13689 continued line of R2L text within an L2R paragraph, or vice versa.
13690 (cursor_row_p): Consider the case of point being equal to
13691 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
13692 from the end of a short line to the beginning of a continued line
13693 of R2L text within L2R paragraph.

13721 instead of CHAR_TO_BYTE. Fixes a crash when a completion
13722 candidate is selected by the mouse, and that candidate has a
13723 composed character under the mouse.
13725 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
13726 coordinates reported by pos-visible-in-window-p for a composed
13727 character in column zero.

13735 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
13736 consider it a hit if to_charpos is anywhere in the range of the
13737 composed buffer positions.
13739 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
13741 * image.c (gif_load): Don't assume that each subimage has the same
13742 dimensions as the base image. Handle disposal method that is
13743 "undefined" by the gif spec (Bug#9335).
13745 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
13747 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

13757 a composition, take its buffer position from IT->cmp_it.charpos.
13758 Fixes cursor positioning at the beginning of a line that begins
13759 with a composed character.
13761 2011-08-18 Eli Zaretskii <eliz@gnu.org>
13763 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
13764 character bidirectional type, use STRONG_L instead. Fixes crashes
13765 in a buffer produced by `describe-categories'.
13767 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
13768 members before the level stack, so they would be saved and
13769 restored when copying iterator state. Fixes incorrect reordering
13770 around TABs covered by display properties.
13772 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

13857 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
13858 the event loop. Get status from as_status (Bug#7276).
13860 * nsterm.m (sendEvent): If event is NSApplicationDefined and
13861 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
13862 the event loop (Bug#7276).
13864 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
13866 * gnutls.c (QCgnutls_bootprop_priority)
13867 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
13868 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
13869 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
13870 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
13871 (QCgnutls_bootprop_verify_hostname_error)
13872 (QCgnutls_bootprop_callbacks_verify): Rename from
13873 Qgnutls_bootprop_..., all uses changed.
13875 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
13878 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
13880 * xfaces.c (Qframe_set_background_mode): Now static.
13881 * dispextern.h (Qframe_set_background_mode): Remove decl.
13883 * process.c (Fnetwork_interface_info): Declare local only if needed.
13885 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
13887 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
13888 (Fnetwork_interface_list): Allocate in increments of bytes instead
13889 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
13890 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
13892 (struct ifflag_def): notrailers is smart on OSX.
13893 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
13894 Get hardware address with getifaddrs if available.
13896 2011-08-12 Eli Zaretskii <eliz@gnu.org>
13898 * xdisp.c (iterate_out_of_display_property): xassert that
13899 IT->position is set to within IT->object's boundaries. Break from
13900 the loop as soon as EOB is reached; avoids infloops in redisplay
13901 when IT->position is set up wrongly due to some bug.
13902 Set IT->current to match the bidi iterator unconditionally.
13903 (push_display_prop): Allow GET_FROM_STRING as IT->method on
13904 entry. Force push_it to save on the stack the current
13905 buffer/string position, to be restored by pop_it. Fix flags in
13906 the iterator structure wrt the object coming from a display
13907 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
13908 properties. (Bug#9284)
13910 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
13912 * fontset.c (fontset_get_font_group): Add proper type checks.
13915 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13917 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
13918 and LC_VERSION_MIN_MACOSX.
13919 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
13920 (dump_it) [LC_FUNCTION_STARTS]: Use it.
13922 2011-08-08 Eli Zaretskii <eliz@gnu.org>
13924 * xdisp.c (forward_to_next_line_start): Allow to use the
13925 no-display-properties-and-no-overlays under bidi display.
13926 Set disp_pos in the bidi iterator to avoid searches for display
13927 properties and overlays.
13929 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
13931 * editfns.c (Fset_time_zone_rule): Document relationship with the
13934 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
13935 the font entity extracted from the cache (Bug#8109).
13937 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
13939 * composite.c (autocmp_chars): Don't reset point. That is done by
13940 restore_point_unwind (Bug#5984).
13942 2011-08-07 Juri Linkov <juri@jurta.org>
13944 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
13945 to show the arg `TIME' instead of `TIMEVAL'.
13947 2011-08-06 Eli Zaretskii <eliz@gnu.org>
13949 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
13950 display property strides EOL and includes a newline, as in
13951 longlines-mode. (Bug#9254)
13952 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
13953 word-wrap under bidirectional display. (Bug#9224)
13955 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
13956 is non-zero, even if the data buffer is NULL. Fixes a crash in
13957 vertical-motion with longlines-mode. (Bug#9254)
13959 2011-08-05 Eli Zaretskii <eliz@gnu.org>
13961 * bidi.c <bidi_cache_total_alloc>: Now static.
13962 (bidi_initialize): Initialize bidi_cache_total_alloc.
13964 * xdisp.c (display_line): Release buffer allocated for shelved bidi
13967 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
13968 amount allocated this far in `bidi_cache_total_alloc'.
13969 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
13970 non-zero, only free the data buffer without restoring the cache
13971 contents. All callers changed.
13973 * dispextern.h (bidi_unshelve_cache): Update prototype.
13975 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
13976 (move_it_in_display_line, move_it_to)
13977 (move_it_vertically_backward, move_it_by_lines): Replace the call
13978 to xfree to an equivalent call to bidi_unshelve_cache.
13979 (move_it_in_display_line_to): Fix logic of returning
13980 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
13982 2011-08-05 Eli Zaretskii <eliz@gnu.org>
13984 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
13985 came from a string character with a `cursor' property. (Bug#9229)
13987 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
13989 * Makefile.in (LIB_PTHREAD): New variable.
13990 (LIBES): Add LIB_PTHREAD (Bug#9216).
13992 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
13993 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
13995 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
13997 * regex.c (re_iswctype): Remove some redundant boolean conversions.
13999 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
14001 * xterm.c (x_find_topmost_parent): New function.
14002 (x_set_frame_alpha): Find topmost parent window with
14003 x_find_topmost_parent and set the property there also (bug#9181).
14004 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
14006 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
14008 * callproc.c (Fcall_process): Avoid vfork clobbering
14009 the local vars buffer, coding_systems, current_dir.
14011 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
14013 * keymap.c (Fmake_composed_keymap): Move to subr.el.
14015 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
14017 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
14018 so that it is not optimized away.
14020 * xdisp.c (compute_display_string_pos): Remove unused local.
14022 2011-08-02 Eli Zaretskii <eliz@gnu.org>
14024 Fix slow cursor motion and scrolling in large buffers with
14025 selective display, like Org Mode buffers. (Bug#9218)
14027 * dispextern.h (struct bidi_it): New member disp_prop_p.
14029 * xdisp.c: Remove one-slot cache of display string positions.
14030 (compute_display_string_pos): Accept an additional argument
14031 DISP_PROP_P; callers changed. Scan at most 5K characters forward
14032 for a display string or property. If found, set DISP_PROP_P
14035 * bidi.c (bidi_fetch_char): Accept an additional argument
14036 DISP_PROP_P, and pass it to compute_display_string_pos.
14037 Only handle text covered by a display string if DISP_PROP_P is returned
14038 non-zero. All callers of bidi_fetch_char changed.
14040 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
14042 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
14044 2010-12-03 Don March <don@ohspite.net>
14046 * keymap.c (Fdefine_key): Fix non-prefix key error message when
14047 last character M-[char] is translated to ESC [char] (bug#7541).
14049 2011-08-02 Kenichi Handa <handa@m17n.org>
14051 * lisp.h (uniprop_table): Extern it.
14053 * chartab.c (uniprop_table): Make it non-static.
14055 2011-08-01 Eli Zaretskii <eliz@gnu.org>
14057 * xdisp.c (forward_to_next_line_start): Accept additional argument
14058 BIDI_IT_PREV, and store into it the state of the bidi iterator had
14060 (reseat_at_next_visible_line_start): Use the bidi iterator state
14061 returned by forward_to_next_line_start to restore the state of
14062 it->bidi_it after backing up to previous newline. (Bug#9212)
14064 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
14066 * regex.c (re_comp): Protoize.
14067 (re_exec): Fix return type.
14068 (regexec): Fix type of `ret'. (Bug#9203)
14070 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14072 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
14073 This is needed if max-image-size is a floating-point number.
14075 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
14077 * print.c (print_object): Print empty symbol as ##.
14079 * lread.c (read1): Read ## as empty symbol.
14081 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
14083 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
14084 setting frame foreground color (Bug#9175).
14085 (x_set_background_color): Likewise.
14087 * nsmenu.m (-setText): Size tooltip dimensions precisely to
14088 contents (Bug#9176).
14089 (EmacsTooltip -init): Remove bezels and add shadows to
14092 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
14093 or scroll bar (Bug#8470).
14095 * nsfont.m (nsfont_open): Remove assignment to voffset and
14096 unnecessary vars hshink, expand, hd, full_height, min_height.
14097 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
14099 * nsterm.h (nsfont_info): Remove voffset field.
14101 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
14103 Implement strike-through and overline on NextStep (Bug#8863).
14105 * nsfont.m (nsfont_open): Use underline position provided by font,
14106 instead of hard-coded value of 2.
14107 (nsfont_draw): Call ns_draw_text_decoration instead.
14109 * nsterm.h: Add declaration for ns_draw_text_decoration.
14111 * nsterm.m (ns_draw_text_decoration): New function for drawing
14112 underline, overline, and strike-through.
14113 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
14114 ns_draw_text_decoration. Change treatment of cursor drawing to
14115 accommodate underlining, etc.
14117 2011-07-28 Eli Zaretskii <eliz@gnu.org>
14119 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
14122 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14124 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
14125 Without this fix, if a signal arrives just after memory fills up,
14126 'malloc' might be invoked reentrantly.
14128 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
14129 In other words, assume that every image size is allowed, on non-X
14130 hosts. This assumption is probably wrong, but it lets Emacs compile.
14132 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
14134 * regex.c (re_iswctype): Convert return values to boolean.
14136 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
14138 * xdisp.c (compute_display_string_pos): Don't use cached display
14139 string position if the buffer had its restriction changed.
14142 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14144 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
14146 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14148 Integer signedness and overflow and related fixes. (Bug#9079)
14150 * bidi.c: Integer size and overflow fixes.
14151 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
14152 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
14153 (bidi_cache_find_level_change, bidi_cache_ensure_space)
14154 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
14155 (bidi_find_other_level_edge):
14156 Use ptrdiff_t instead of EMACS_INT where either will do.
14157 This works better on 32-bit hosts configured --with-wide-int.
14158 (bidi_cache_ensure_space): Check for size-calculation overflow.
14159 Use % rather than repeated addition, for better worst-case speed.
14160 Don't set bidi_cache_size until after xrealloc returns, because it
14162 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
14163 (bidi_cache_ensure_space): Also check that the bidi cache size
14164 does not exceed that of the largest Lisp string or buffer. See Eli
14165 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
14167 * alloc.c (__malloc_size_t): Remove.
14168 All uses replaced by size_t. See Andreas Schwab's note
14169 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
14171 * image.c: Improve checking for integer overflow.
14172 (check_image_size): Assume that f is nonnull, since
14173 it is always nonnull in practice. This is one less thing to
14174 worry about when checking for integer overflow later.
14175 (x_check_image_size): New function, which checks for integer
14176 overflow issues inside X.
14177 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
14178 This removes the need for a memory_full check.
14179 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
14180 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
14181 (xbm_read_bitmap_data): Change locals back to 'int', since
14182 their values must fit in 'int'.
14183 (xpm_load_image, png_load, tiff_load):
14184 Invoke x_create_x_image_and_pixmap earlier,
14185 to avoid much needless work if the image is too large.
14186 (tiff_load): Treat overly large images as if
14187 x_create_x_image_and_pixmap failed, not as malloc failures.
14188 (gs_load): Use x_check_image_size.
14190 * gtkutil.c: Omit integer casts.
14191 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
14192 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
14194 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
14196 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
14197 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
14198 would wrongly return t on a 64-bit host.
14200 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
14201 The plain *_OVERFLOW macros run afoul of GCC bug 49705
14202 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
14203 and therefore cause GCC to emit a bogus diagnostic in some cases.
14205 * image.c: Integer signedness and overflow and related fixes.
14206 This is not an exhaustive set of fixes, but it's time to
14207 record what I've got.
14208 (lookup_pixel_color, check_image_size): Remove redundant decls.
14209 (check_image_size): Don't assume that arbitrary EMACS_INT values
14210 fit in 'int', or that arbitrary 'double' values fit in 'int'.
14211 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
14212 (tiff_load, imagemagick_load_image):
14213 Check for overflow in size calculations.
14214 (x_create_x_image_and_pixmap): Remove unnecessary test for
14215 xmalloc returning NULL; that can't happen.
14216 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
14217 (xpm_color_bucket): Use better integer hashing function.
14218 (xpm_cache_color): Don't possibly over-allocate memory.
14219 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
14220 (gif_memory_source):
14221 Use ptrdiff_t, not int or size_t, to record sizes.
14222 (png_load): Don't assume values greater than 2**31 fit in 'int'.
14223 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
14224 either works, as we prefer signed integers.
14225 (tiff_read_from_memory, tiff_write_from_memory):
14226 Return tsize_t, not size_t, since that's what the TIFF API wants.
14227 (tiff_read_from_memory): Don't fail simply because the read would
14228 go past EOF; instead, return a short read.
14229 (tiff_load): Omit no-longer-needed casts.
14230 (Fimagemagick_types): Don't assume size fits into 'int'.
14232 Improve hashing quality when configured --with-wide-int.
14233 * fns.c (hash_string): New function, taken from sxhash_string.
14234 Do not discard information about ASCII character case; this
14235 discarding is no longer needed.
14236 (sxhash-string): Use it. Change sig to match it. Caller changed.
14237 * lisp.h: Declare it.
14238 * lread.c (hash_string): Remove, since we now use fns.c's version.
14239 The fns.c version returns a wider integer if --with-wide-int is
14240 specified, so this should help the quality of the hashing a bit.
14242 * emacs.c: Integer overflow minor fix.
14243 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
14244 Define only if GNU_LINUX.
14245 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
14247 * dispnew.c: Integer signedness and overflow fixes.
14248 Remove unnecessary forward decls, that were a maintenance hassle.
14249 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
14251 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
14252 (scrolling_window): Use ptrdiff_t, not int, for byte count.
14253 (prepare_desired_row, line_draw_cost):
14254 Use int, not unsigned, where either works.
14255 (save_current_matrix, restore_current_matrix):
14256 Use ptrdiff_t, not size_t, where either works.
14257 (init_display): Check for overflow more accurately, and without
14258 relying on undefined behavior.
14260 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
14261 Remove, replacing with the new symbols in lisp.h. All uses changed.
14262 * fileio.c (make_temp_name):
14263 * filelock.c (lock_file_1, lock_file):
14264 * xdisp.c (message_dolog):
14265 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
14266 Use pMd etc. instead.
14267 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
14268 replacing the pWIDE etc. symbols removed from editfns.c.
14270 * keyboard.h (num_input_events): Now uintmax_t.
14271 This is (very slightly) less likely to mess up due to wraparound.
14274 * buffer.c: Integer signedness fixes.
14275 (alloc_buffer_text, enlarge_buffer_text):
14276 Use ptrdiff_t rather than size_t when either will do, as we prefer
14279 * alloc.c: Integer signedness and overflow fixes.
14280 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
14281 (__malloc_size_t): Default to size_t, not to int.
14282 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
14283 (Fgarbage_collect, mark_object_loop_halt, mark_object):
14284 Prefer ptrdiff_t to size_t when either would do, as we prefer
14286 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
14287 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
14288 Now const. Initialize with values that are in range even if char
14290 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
14291 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
14292 These functions do the right thing with sizes > 2**32.
14293 (check_depth): Now ptrdiff_t, not int.
14294 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
14295 Adjust to new way of storing sizes. Check for size overflow bugs
14297 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
14298 slightly wrong anyway, as it missed one instance of
14299 XMALLOC_OVERRUN_CHECK_OVERHEAD.
14300 (refill_memory_reserve): Omit needless cast to size_t.
14301 (mark_object_loop_halt): Mark as externally visible.
14303 * xselect.c: Integer signedness and overflow fixes.
14304 (Fx_register_dnd_atom, x_handle_dnd_message):
14305 Use ptrdiff_t, not size_t, since we prefer signed.
14306 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
14307 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
14308 x_dnd_atoms_size and x_dnd_atoms_length.
14310 * doprnt.c: Prefer signed to unsigned when either works.
14312 * doprnt.c (doprnt):
14314 * xdisp.c (vmessage):
14315 Use ptrdiff_t, not size_t, when using or implementing doprnt,
14316 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
14317 prefer signed arithmetic to avoid comparison confusion.
14318 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
14319 but is a bit tricky.
14321 Assume freestanding C89 headers, string.h, stdlib.h.
14322 * data.c, doprnt.c, floatfns.c, print.c:
14323 Include float.h unconditionally.
14324 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
14325 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
14326 * regex.c: Likewise for stddef.h, string.h.
14327 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
14328 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
14329 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
14330 (STDC_HEADERS): Remove obsolete defines.
14331 * sysdep.c: Include limits.h unconditionally.
14333 Assume support for memcmp, memcpy, memmove, memset.
14334 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
14335 * regex.c (memcmp, memcpy):
14336 Remove; we assume C89 now.
14338 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
14339 (__malloc_safe_bcopy): Remove; no longer needed.
14341 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
14342 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
14343 well either way, and we prefer signed to unsigned.
14345 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
14347 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
14348 closes the connection while we're reading (bug#9182).
14350 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
14352 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
14353 are specified (Bug#9168).
14355 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
14357 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
14358 Found by GCC static checking and --with-wide-int on a 32-bit host.
14360 2011-07-25 Eli Zaretskii <eliz@gnu.org>
14362 * xdisp.c (compute_display_string_pos): Fix logic of caching
14363 previous display string position. Initialize cached_prev_pos to
14364 -1. Fixes slow-down at the beginning of a buffer.
14366 2011-07-24 Eli Zaretskii <eliz@gnu.org>
14368 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
14369 for attrs[LFACE_FONTSET_INDEX].
14371 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
14373 * xml.c (parse_region): Remove unused local
14374 that was recently introduced.
14376 2011-07-23 Eli Zaretskii <eliz@gnu.org>
14378 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
14379 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
14381 * xdisp.c (move_it_in_display_line_to): Record the best matching
14382 position for TO_CHARPOS while scanning the line, and restore it on
14383 exit if none of the characters scanned was an exact match.
14384 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
14385 when exact match is impossible due to invisible text, and the
14386 lines are truncated.
14388 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
14390 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
14393 2011-07-22 Eli Zaretskii <eliz@gnu.org>
14395 Fix a significant slow-down of cursor motion with C-n, C-p,
14396 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
14397 auto-repeat under bidi redisplay in fontified buffers.
14398 * xdisp.c (compute_stop_pos_backwards): New function.
14399 (next_element_from_buffer): Call compute_stop_pos_backwards to
14400 find a suitable prev_stop when we find ourselves before
14402 (reseat): Don't look for prev_stop, as that could mean a very long
14404 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
14405 <cached_disp_overlay_modiff>: Cache for last found display string
14407 (compute_display_string_pos): Return the cached position if asked
14408 about the same buffer in the same area of character positions, and
14409 the buffer wasn't changed since the time the display string
14410 position was cached.
14412 2011-07-22 Eli Zaretskii <eliz@gnu.org>
14414 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
14415 is an integer, which is important for empty lines. (Bug#9149)
14417 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
14419 * frame.c (Fmodify_frame_parameters): In tty case, update the
14420 default face if necessary (Bug#4238).
14422 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
14424 * editfns.c (Fstring_to_char): No need to explain what a character
14425 is in the docstring (Bug#6576).
14427 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
14429 * xml.c (parse_region): Make sure we always return a tree.
14431 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
14433 * xml.c (parse_region): If a document contains only comments,
14436 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
14438 * xml.c (make_dom): Return comments, too.
14440 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
14443 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
14444 and the surrounding thread.
14445 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
14446 rather than fgets, and retry after EINTR. Otherwise, 'emacs
14447 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
14449 * s/openbsd.h (BROKEN_SIGIO): Define.
14450 * unexelf.c (unexec) [__OpenBSD__]:
14451 Don't update the .mdebug section of the Alpha COFF symbol table.
14453 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14455 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
14458 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
14460 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
14461 This fixes some race conditions on the permissions of any newly
14464 * alloc.c (valid_pointer_p): Use pipe, not open.
14465 This fixes some permissions issues when debugging.
14467 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
14468 If fchown fails to set both uid and gid, try to set just gid,
14469 as that is sometimes allowed. Adjust the file's mode to eliminate
14470 setuid or setgid bits that are inappropriate if fchown fails.
14472 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
14474 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
14475 to compare Lisp_Objects.
14476 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
14477 global_gnutls_log_level, don't mistake it for a Lisp_Object.
14478 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
14480 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
14482 * lread.c (read_integer): Unread even EOF character.
14483 (read1): Likewise. Properly record start position of symbol.
14485 * lread.c (read1): Read `#:' as empty uninterned symbol if no
14486 symbol character follows.
14488 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
14490 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
14491 This works around a problem with the previous change to Fcopy_file.
14492 Recent glibc declares fchown with __attribute__((warn_unused_result)),
14493 and without this change, GCC might complain about discarding
14494 fchown's return value.
14496 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
14498 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
14500 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
14502 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
14504 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
14506 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
14507 it's used from the C level.
14509 * process.c: Use the same condition for POLL_FOR_INPUT in both
14510 keyboard.c and process.c (bug#1858).
14512 2011-07-09 Lawrence Mitchell <wence@gmx.li>
14514 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
14515 (Fgnutls_boot): Use it.
14517 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
14519 * doc.c (Fsubstitute_command_keys): Revert last change.
14521 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
14523 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
14524 quotes the next character, and doesn't affect other longer
14525 sequences (bug#8935).
14527 * lread.c (syms_of_lread): Clarify that is isn't only
14528 `eval-buffer' and `eval-defun' that's affected by
14529 `lexical-binding' (bug#8460).
14531 2011-07-15 Eli Zaretskii <eliz@gnu.org>
14533 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
14534 bidi redisplay when a line includes both an image and is truncated.
14536 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
14538 Fix minor problems found by static checking.
14539 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
14540 (elsz): Now a signed constant, not a size_t var. We prefer signed
14541 types to unsigned, to avoid integer comparison confusion. Without
14542 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
14543 "cannot optimize loop, the loop counter may overflow", a symptom
14545 * indent.c (Fvertical_motion): Mark locals as initialized.
14546 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
14548 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
14550 * search.c (Fre_search_backward): Mention `case-fold-search' in
14551 all the re_search_* functions (bug#8138).
14553 * keyboard.c (Fopen_dribble_file): Document when the file is

14566 bidi_it->string.schars.
14567 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
14568 NULL (avoids a crash in bidi_paragraph_init).
14569 Initialize itb.string.lstring.
14570 (init_iterator): Call bidi_init_it only of a valid
14571 buffer position was specified. Initialize paragraph_embedding to
14573 (reseat_to_string): Initialize the bidi iterator.
14574 (display_string): If we need to ignore text properties of
14575 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
14576 original value of -1 will not work with bidi.)
14577 (compute_display_string_pos): First arg is now struct
14578 `text_pos *'; all callers changed. Support display properties on
14580 (compute_display_string_end): Support display properties on Lisp
14582 (init_iterator, reseat_1, reseat_to_string): Initialize the
14583 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
14584 when iterating on a string not from display properties).
14585 (compute_display_string_pos, compute_display_string_end):
14586 Fix calculation of the object to scan. Fixes an error when using
14588 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
14589 base_level_stop; instead, set base_level_stop to BEGV.
14590 Fixes crashes in vertical-motion.
14591 (next_element_from_buffer): Improve commentary for when
14592 the iterator is before prev_stop.
14593 (init_iterator): Initialize bidi_p from the default value of
14594 bidi-display-reordering, not from buffer-local value. Use the
14595 buffer-local value only if initializing for buffer iteration.
14596 (handle_invisible_prop): Support invisible properties on strings
14597 that are being bidi-reordered.
14598 (set_iterator_to_next): Support bidi reordering of C strings and
14600 (next_element_from_string): Support bidi reordering of Lisp
14602 (handle_stop_backwards): Support Lisp strings as well.
14603 (display_string): Support display of R2L glyph rows.
14604 Use IT_STRING_CHARPOS when displaying from a Lisp string.
14605 (init_iterator): Don't initialize it->bidi_p for strings
14607 (reseat_to_string): Initialize it->bidi_p for strings here.
14608 (next_element_from_string, next_element_from_c_string)
14609 (next_element_from_buffer): Add xassert's for correspondence
14610 between IT's object being iterated and it->bidi_it.string

14613 (next_element_from_c_string): Handle the case of the first string
14614 character that is not the first one in the visual order.
14615 (get_visually_first_element): New function, refactored from common
14616 parts of next_element_from_buffer, next_element_from_string, and
14617 next_element_from_c_string.
14618 (tool_bar_lines_needed, redisplay_tool_bar)
14619 (display_menu_bar): Force left-to-right direction. Add a FIXME
14620 comment for making that be controlled by a user option.
14621 (push_it, pop_it): Save and restore the state of the
14622 bidi iterator. Save and restore the bidi_p flag.
14623 (pop_it): Iterate out of display property for string iteration as
14625 (iterate_out_of_display_property): Support iteration over strings.
14626 (handle_single_display_spec): Set up it->bidi_it for iteration
14627 over a display string, and call bidi_init_it.
14628 (handle_single_display_spec, next_overlay_string)
14629 (get_overlay_strings_1, push_display_prop): Set up the bidi
14630 iterator for displaying display or overlay strings.
14631 (forward_to_next_line_start): Don't use the shortcut if
14633 (back_to_previous_visible_line_start): If handle_display_prop
14634 pushed the iterator stack, restore the internal state of the bidi
14635 iterator by calling bidi_pop_it same number of times.
14636 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
14637 and we are bidi-iterating, don't decrement the iterator position;
14638 instead, set the first_elt flag in the bidi iterator, to produce
14640 (reseat_1): Remove redundant setting of string_from_display_prop_p.
14641 (push_display_prop): xassert that we are iterating a buffer.
14642 (push_it, pop_it): Save and restore paragraph_embedding member.
14643 (handle_single_display_spec, next_overlay_string)
14644 (get_overlay_strings_1, reseat_1, reseat_to_string)
14645 (push_display_prop): Set up the `unibyte' member of bidi_it.string
14646 correctly. Don't assume unibyte strings are not bidi-reordered.
14647 (compute_display_string_pos)
14648 (compute_display_string_end): Fix handling the case of C string.
14649 (push_it, pop_it): Save and restore from_disp_prop_p.

14654 popping after iteration over a string that came from a display
14655 property. Fix a typo in popping stretch info. Add an assertion
14656 for verifying that the iterator position is in sync with the bidi
14658 (handle_single_display_spec, get_overlay_strings_1)
14659 (push_display_prop): Fix initialization of paragraph direction for
14660 string when that of the parent object is not yet determined.
14661 (reseat_1): Call bidi_init_it to resync the bidi
14662 iterator with IT's position. (Bug#7616)
14663 (find_row_edges): If ROW->start.pos gives position
14664 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
14665 (handle_stop, back_to_previous_visible_line_start, reseat_1):
14666 Reset the from_disp_prop_p flag.
14667 (SAVE_IT, RESTORE_IT): New macros.

14669 (back_to_previous_visible_line_start)
14670 (move_it_in_display_line_to, move_it_in_display_line)
14671 (move_it_to, move_it_vertically_backward, move_it_by_lines)
14672 (try_scrolling, redisplay_window, display_line): Use them when
14673 saving a temporary copy of the iterator and restoring it back.
14674 (back_to_previous_visible_line_start, reseat_1)
14675 (init_iterator): Empty the bidi cache "stack".
14676 (move_it_in_display_line_to): If iterator ended up at
14677 EOL, but we never saw any buffer positions smaller than
14678 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
14679 motion in bidi-reordered lines.
14680 (move_it_in_display_line_to): Record prev_method and prev_pos
14681 immediately before the call to set_iterator_to_next. Fixes cursor
14682 motion in bidi-reordered lines with stretch glyphs and strings
14683 displayed in margins. (Bug#8133) (Bug#8867)
14684 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
14686 (pos_visible_p): Support positions in bidi-reordered lines.
14687 Save and restore bidi cache.
14689 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
14690 (bidi_paragraph_info): Delete unused struct.
14691 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
14692 (bidi_cache_start): New variable.
14693 (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not
14695 (bidi_cache_fetch_state, bidi_cache_search)
14696 (bidi_cache_find_level_change, bidi_cache_iterator_state)

14701 (bidi_fetch_char): Accept new argument STRING; all callers
14702 changed. Support iteration over a string. Support strings with
14703 display properties. Support unibyte strings. Fix the type of
14704 `len' according to what STRING_CHAR_AND_LENGTH expects.
14705 (bidi_paragraph_init, bidi_resolve_explicit_1)
14706 (bidi_resolve_explicit, bidi_resolve_weak)
14707 (bidi_level_of_next_char, bidi_move_to_visually_next):
14708 Support iteration over a string.
14709 (bidi_set_sor_type, bidi_resolve_explicit_1)
14710 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
14711 can now be zero (for strings); special values 0 and -1 were
14712 changed to -1 and -2, respectively.
14713 (bidi_char_at_pos): New function.
14714 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):
14715 Call it instead of FETCH_MULTIBYTE_CHAR.

14725 (bidi_initialize): Initialize the bidi cache start stack pointer.
14726 (bidi_cache_ensure_space): New function, refactored from part of

14800 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
14802 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
14803 The old code sometimes used this field without initializing it.
14805 * alloc.c (gc_sweep): Don't read past end of array.
14806 In theory, the old code could also have corrupted Emacs internals,
14807 though it'd be very unlikely.

15072 This isn't true in general, and it's particularly not true
15073 if Emacs is configured with --with-wide-int.
15074 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):

15111 Random fixes. E.g., (random) never returned negative values.
15112 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
15113 subseconds part to the entropy, as that's a bit more random.
15114 Prefer signed to unsigned, since the signedness doesn't matter and
15115 in general we prefer signed. When given a limit, use a
15116 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
15117 latter isn't right if USE_2_TAGS_FOR_INTS.
15118 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
15119 not 0..VALMASK. Don't discard "excess" bits that random () returns.

15131 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
15132 This is more efficient than Ffile_directory_p and avoids a minor race.
15134 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
15136 * buffer.c (Foverlay_put): Say what the return value is
15139 * fileio.c (barf_or_query_if_file_exists): Check first if the file
15140 is a directory before asking whether to use the file name
15142 (barf_or_query_if_file_exists): Make the "File is a directory"
15143 error be more correct.
15145 * fns.c (Frequire): Remove the mention of the .gz files, since
15146 that's installation-specific, but keep the mention of

15159 Qgnutls_bootprop_verify_error (which is no longer used).
15161 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
15162 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
15163 Also (re)move comments that are misplaced or no longer relevant.
15165 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15167 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

15264 * eval.c (struct backtrace): Simplify and port the data structure.
15265 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
15266 signed bit field, as this assumption is not portable and it makes
15267 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
15268 "char debug_on_exit : 1" as this is not portable either; instead,
15269 use the portable "unsigned int debug_on_exit : 1". Remove unused
15270 member evalargs. Remove obsolete comments about cc bombing out.
15272 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

15344 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
15345 and use min_width/height from frames size_hint to set
15346 min_width/height (Bug#8919).

15439 (PRINTPREPARE, printchar, strout):
15440 Don't set size unless allocation succeeds.
15442 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
15443 for sizes. Check for string overflow more accurately.

15460 (read1): Check for integer overflow in radices, and in
15461 read-circle numbers.
15462 (read_escape): Avoid int overflow.
15463 (Fload, openp, read_buffer_size, read1)
15464 (substitute_object_recurse, read_vector, read_list, map_obarray):

15505 on undefined behavior with wrong number of arguments.
15506 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
15507 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
15508 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
15509 since we're not interested in debugging glyphs with old libraries.
15510 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
15511 GCC 4.6.0's static checking.
15513 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

15552 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
15553 (x_session_initialize): Do not assume string length fits in int.
15555 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
15556 This is unlikely, but can occur if DPI is outlandish.
15558 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):

15581 * minibuf.c (Fread_buffer):
15582 * lread.c (intern, intern_c_string):
15583 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

15601 Don't assume pid_t and time_t fit in unsigned long.
15602 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
15603 (current_lock_owner): Prefer signed type for sizes.
15604 Use memcpy, not strncpy, where memcpy is what is really wanted.
15605 Don't assume (via atoi) that time_t and pid_t fit in int.
15606 Check for time_t and/or pid_t out of range, e.g., via a network share.
15607 Don't alloca where an auto var works fine.
15609 * fileio.c: Fix some integer overflow issues.

15612 (directory_file_name): Don't assume string length fits in long.
15613 (make_temp_name): Don't assume pid fits in int, or that its print
15614 length is less than 20.
15616 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
15618 * coding.c (make_subsidiaries): Don't assume string length fits in int.
15620 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
15622 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
15623 We prefer signed integers, even for size calculations.
15625 * emacs.c: Don't assume string length fits in 'int'.
15626 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
15627 (main): Don't invoke strlen when not needed.
15629 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
15630 (XD_DEBUG_MESSAGE): Don't waste a byte.
15632 * callproc.c (getenv_internal_1, getenv_internal)
15633 (Fgetenv_internal):
15634 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
15636 * lread.c (invalid_syntax): Omit length argument.
15637 All uses changed. This doesn't fix a bug, but it simplifies the
15638 code away from its former Hollerith-constant appearance, and it's
15639 one less 'int' to worry about when looking at integer-overflow issues.
15640 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
15642 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
15643 This didn't break anything, but it didn't help either.
15644 It's confusing to put a bogus integer in a place where the actual
15645 value does not matter.
15646 (LIST_END_P): Remove unused macro and its bogus comment.
15647 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
15649 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
15650 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
15652 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
15653 We prefer signed types, and the value cannot exceed the EMACS_INT
15654 range anyway (because otherwise the length would not be representable).
15655 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
15656 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
15657 This avoids a GCC warning when WIDE_EMACS_INT.
15659 * indent.c (sane_tab_width): New function.
15660 (current_column, scan_for_column, Findent_to, position_indentation)
15661 (compute_motion): Use it. This is just for clarity.
15662 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
15664 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
15666 * lisp.h (lint_assume): New macro.
15667 * composite.c (composition_gstring_put_cache):
15668 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
15670 * editfns.c, insdel.c:
15671 Omit unnecessary forward decls, to simplify future changes.
15673 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
15675 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
15677 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
15678 Use much-faster test for byte-length change.
15679 Don't assume string byte-length fits in 'int'.
15680 Check that character arg fits in 'int'.
15681 (mapcar1): Declare byte as byte, for clarity.
15683 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
15685 * fns.c (concat): Catch string overflow earlier.
15686 Do not rely on integer wraparound.
15688 * dispextern.h (struct it.overlay_strings_charpos)
15689 (struct it.selective): Now EMACS_INT, not int.
15690 * xdisp.c (forward_to_next_line_start)
15691 (back_to_previous_visible_line_start)
15692 (reseat_at_next_visible_line_start, next_element_from_buffer):
15693 Don't arbitrarily truncate the value of 'selective' to int.
15695 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
15697 * composite.c: Don't truncate sizes to 'int'.
15698 (composition_gstring_p, composition_reseat_it)
15699 (composition_adjust_point): Use EMACS_INT, not int.
15700 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
15701 not EMACS_UINT, for indexes.
15703 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
15705 * buffer.c: Include <verify.h>.
15706 (struct sortvec.priority, struct sortstr.priority):
15707 Now EMACS_INT, not int.
15708 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
15709 (struct sortstr.size, record_overlay_string)
15710 (struct sortstrlist.size, struct sortlist.used):
15711 Don't truncate size to int.
15712 (record_overlay_string): Check for size-calculation overflow.
15713 (init_buffer_once): Check at compile-time, not run-time.
15715 2011-06-22 Jim Meyering <meyering@redhat.com>
15717 Don't leak an XBM-image-sized buffer
15718 * image.c (xbm_load): Free the image buffer after using it.
15720 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
15723 * composite.c (find_automatic_composition): Omit needless 'return 0;'
15724 that Sun C diagnosed.
15725 * fns.c (secure_hash): Fix pointer signedness issue.
15726 * intervals.c (static_offset_intervals): New function.
15727 (offset_intervals): Use it.
15729 2011-06-21 Leo Liu <sdl.web@gmail.com>
15732 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
15735 * fns.c (secure_hash): Rename from crypto_hash_function and change
15736 the first arg to accept symbols.
15737 (Fsecure_hash): New primitive.
15738 (syms_of_fns): New symbols.
15740 2011-06-20 Deniz Dogan <deniz@dogan.se>
15742 * process.c (Fset_process_buffer): Clarify return value in
15745 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
15747 * dispnew.c (add_window_display_history): Use BVAR.
15749 * xdisp.c (debug_method_add): Use BVAR.
15750 (check_window_end, dump_glyph_matrix, dump_glyph)
15751 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
15753 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
15756 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
15757 check till after the cache is created in init_frame_faces.
15759 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
15761 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
15763 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
15765 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
15766 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
15767 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
15769 Improve buffer-overflow checking (Bug#8873).
15770 * fileio.c (Finsert_file_contents):
15771 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
15772 Remove the old (too-loose) buffer overflow checks.
15773 They weren't needed, since make_gap checks for buffer overflow.
15774 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
15775 The old code merely checked for Emacs fixnum overflow, and relied
15776 on undefined (wraparound) behavior. The new code avoids undefined
15777 behavior, and also checks for ptrdiff_t and/or size_t overflow.
15779 * editfns.c (Finsert_char): Don't dump core with very negative counts.
15780 Tune. Don't use wider integers than needed. Don't use alloca.
15781 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
15783 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
15785 * insdel.c, lisp.h (buffer_overflow): New function.
15786 (insert_from_buffer_1, replace_range, replace_range_2):
15787 * insdel.c (make_gap_larger):
15788 * editfns.c (Finsert_char):
15789 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
15791 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
15793 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
15795 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
15797 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
15798 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
15800 * fileio.c: Don't assume EMACS_INT fits in off_t.
15801 (emacs_lseek): New static function.
15802 (Finsert_file_contents, Fwrite_region): Use it.
15803 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
15805 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
15807 * fns.c: Don't overflow int when computing a list length.
15808 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
15809 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
15810 truncation on 64-bit hosts. Check for QUIT every
15811 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
15812 faster and is responsive enough.
15813 (Flength): Report an error instead of overflowing an integer.
15814 (Fsafe_length): Return a float if the value is not representable
15815 as a fixnum. This shouldn't happen except in contrived situations.
15816 (Fnthcdr, Fsort): Don't assume list length fits in int.
15817 (Fcopy_sequence): Don't assume vector length fits in int.
15819 * alloc.c: Check that resized vectors' lengths fit in fixnums.
15820 (header_size, word_size): New constants.
15821 (allocate_vectorlike): Don't check size overflow here.
15822 (allocate_vector): Check it here instead, since this is the only
15823 caller of allocate_vectorlike that could cause overflow.
15824 Check that the new vector's length is representable as a fixnum.
15826 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
15827 The previous code was bogus. For example, next_almost_prime (32)
15828 returned 39, which is undesirable as it is a multiple of 3; and
15829 next_almost_prime (24) returned 25, which is a multiple of 5 so
15830 why was the code bothering to check for multiples of 7?
15832 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
15834 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
15836 Variadic C functions now count arguments with ptrdiff_t.
15837 This partly undoes my 2011-03-30 change, which replaced int with size_t.
15838 Back then I didn't know that the Emacs coding style prefers signed int.
15839 Also, in the meantime I found a few more instances where arguments
15840 were being counted with int, which may truncate counts on 64-bit
15841 machines, or EMACS_INT, which may be unnecessarily wide.
15842 * lisp.h (struct Lisp_Subr.function.aMANY)
15843 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
15844 Arg counts are now ptrdiff_t, not size_t.
15845 All variadic functions and their callers changed accordingly.
15846 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
15847 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
15848 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
15849 * callint.c (Fcall_interactively): Check arg count for overflow,
15850 to avoid potential buffer overrun. Use signed char, not 'int',
15851 for 'varies' array, so that we needn't bother to check its size
15852 calculation for overflow.
15853 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
15854 * eval.c (apply_lambda):
15855 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
15856 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
15857 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
15859 * callint.c (Fcall_interactively): Don't use index var as event count.
15861 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
15862 * mem-limits.h (SIZE): Remove; no longer used.
15864 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
15866 Remove unnecessary casts.
15867 * xterm.c (x_term_init):
15868 * xfns.c (x_set_border_pixel):
15869 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
15870 These aren't needed now that we assume ANSI C.
15872 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
15873 It's more likely to cause problems (due to unsigned overflow)
15876 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
15878 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
15880 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
15882 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
15884 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
15886 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
15888 GLYPH_CODE_FACE returns EMACS_INT, not int.
15889 * dispextern.h (merge_faces):
15890 * xfaces.c (merge_faces):
15891 * xdisp.c (get_next_display_element, next_element_from_display_vector):
15892 Don't assume EMACS_INT fits in int.
15894 * character.h (CHAR_VALID_P): Remove unused parameter.
15895 * fontset.c, lisp.h, xdisp.c: All uses changed.
15897 * editfns.c (Ftranslate_region_internal): Omit redundant test.
15899 * fns.c (concat): Minor tuning based on overflow analysis.
15900 This doesn't fix any bugs. Use int to hold character, instead
15901 of constantly refetching from Emacs object. Use XFASTINT, not
15902 XINT, for value known to be a character. Don't bother comparing
15903 a single byte to 0400, as it's always less.
15905 * floatfns.c (Fexpt):
15906 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
15908 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
15911 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
15913 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
15914 Without this fix, on a 64-bit host (aset S 0 4294967386) would
15915 incorrectly succeed when S was a string, because 4294967386 was
15916 truncated before it was used.
15918 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
15919 Otherwise, an out-of-range integer could cause undefined behavior
15922 * composite.c: Use int, not EMACS_INT, for characters.
15923 (fill_gstring_body, composition_compute_stop_pos): Use int, not
15924 EMACS_INT, for values that are known to be in character range.
15925 This doesn't fix any bugs but is the usual style inside Emacs and
15926 may generate better code on 32-bit machines.
15928 Make sure a 64-bit char is never passed to ENCODE_CHAR.
15929 This is for reasons similar to the recent CHAR_STRING fix.
15930 * charset.c (Fencode_char): Check that character arg is actually
15931 a character. Pass an int to ENCODE_CHAR.
15932 * charset.h (ENCODE_CHAR): Verify that the character argument is no
15933 wider than 'int', as a compile-time check to prevent future regressions
15936 * character.c (char_string): Remove unnecessary casts.
15938 Make sure a 64-bit char is never passed to CHAR_STRING.
15939 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
15940 by silently ignoring the top 32 bits, allowing some values
15941 that were far too large to be valid characters.
15942 * character.h: Include <verify.h>.
15943 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
15944 arguments are no wider than unsigned, as a compile-time check
15945 to prevent future regressions in this area.
15947 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
15948 (Fsubst_char_in_region):
15950 * xdisp.c (decode_mode_spec_coding):
15951 Adjust to CHAR_STRING's new requirement.
15952 * editfns.c (Finsert_char, Fsubst_char_in_region):
15953 * fns.c (concat): Check that character args are actually
15954 characters. Without this test, these functions did the wrong
15955 thing with wildly out-of-range values on 64-bit hosts.
15957 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
15958 These casts should not be needed on 32-bit hosts, either.
15959 * keyboard.c (read_char):
15960 * lread.c (Fload): Remove casts to unsigned.
15962 * lisp.h (UNSIGNED_CMP): New macro.
15963 This fixes comparison bugs on 64-bit hosts.
15964 (ASCII_CHAR_P): Use it.
15965 * casefiddle.c (casify_object):
15966 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
15967 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
15968 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
15969 * dispextern.h (FACE_FROM_ID):
15970 * keyboard.c (read_char): Use UNSIGNED_CMP.
15972 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
15973 not to EMACS_INT, to avoid GCC warning.
15975 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
15977 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
15978 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
15979 isn't needed on 32-bit machines.
15981 * buffer.c (Fgenerate_new_buffer_name):
15982 Use EMACS_INT for count, not int.
15983 (advance_to_char_boundary): Return EMACS_INT, not int.
15985 * data.c (Qcompiled_function): Now static.
15987 * window.c (window_body_lines): Now static.
15989 * image.c (gif_load): Rename local to avoid shadowing.
15991 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
15992 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
15993 * alloc.c (make_save_value): Integer argument is now of type
15994 ptrdiff_t, not int.
15995 (mark_object): Use ptrdiff_t, not int.
15996 * lisp.h (pD): New macro.
15997 * print.c (print_object): Use it.
15999 * alloc.c: Use EMACS_INT, not int, to count objects.
16000 (total_conses, total_markers, total_symbols, total_vector_size)
16001 (total_free_conses, total_free_markers, total_free_symbols)
16002 (total_free_floats, total_floats, total_free_intervals)
16003 (total_intervals, total_strings, total_free_strings):
16004 Now EMACS_INT, not int. All uses changed.
16005 (Fgarbage_collect): Compute overall total using a double, so that
16006 integer overflow is less likely to be a problem. Check for overflow
16007 when converting back to an integer.
16008 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
16009 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
16010 These were 'int' variables that could overflow on 64-bit hosts;
16011 they were never used, so remove them instead of repairing them.
16012 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
16013 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
16014 Previously, this ceilinged at INT_MAX, but that doesn't work on
16016 (allocate_pseudovector): Don't use EMACS_INT when int would do.
16018 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
16019 (allocate_vectorlike): Check for ptrdiff_t overflow.
16020 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
16021 when a (possibly-narrower) signed value would do just as well.
16022 We prefer using signed arithmetic, to avoid comparison confusion.
16024 * alloc.c: Catch some string size overflows that we were missing.
16025 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
16026 for convenience in STRING_BYTES_MAX.
16027 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
16028 The definition here is exact; the one in lisp.h was approximate.
16029 (allocate_string_data): Check for string overflow. This catches
16030 some instances we weren't catching before. Also, it catches
16031 size_t overflow on (unusual) hosts where SIZE_MAX <= min
16032 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
16033 and ptrdiff_t and EMACS_INT are both 64 bits.
16035 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
16036 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
16037 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
16039 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
16041 * alloc.c (Fmake_string): Check for out-of-range init.
16043 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
16045 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
16047 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
16049 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
16050 xg_get_default_scrollbar_width.
16052 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
16053 (int_gtk_range_get_value): Move to the scroll bar part of the file.
16054 (style_changed_cb): Call update_theme_scrollbar_width and call

16537 code. Minor doc-string fixes.
16539 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
16541 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
16542 Do not assume that spare memory exists; that assumption is valid
16543 only if SYSTEM_MALLOC.
16544 (LARGE_REQUEST): New macro, so that the issue of large requests
16545 is separated from the issue of spare memory.
16547 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
16549 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

16575 New error handlers.
16576 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
16577 Obey Vx_select_enable_clipboard_manager. Catch errors in

16597 Support bidi reordering of text covered by display properties.
16599 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
16600 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
16601 (bidi_cache_search, bidi_cache_iterator_state)
16602 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
16603 (bidi_level_of_next_char, bidi_move_to_visually_next):
16604 Support character positions inside a run of characters covered by a
16606 (bidi_paragraph_init, bidi_resolve_explicit_1)
16607 (bidi_level_of_next_char): Call bidi_fetch_char and
16608 bidi_fetch_char_advance instead of FETCH_CHAR and
16609 FETCH_CHAR_ADVANCE.

16611 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
16613 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
16614 instead of using explicit *_CHAR codes.
16615 (bidi_resolve_explicit, bidi_resolve_weak):
16616 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
16617 bidirectional text is supported only in multibyte buffers.
16618 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
16619 it to initialize the frame_window_p member of struct bidi_it.
16620 (bidi_cache_iterator_state, bidi_resolve_explicit_1)

16623 bidi_it->nchars is non-positive.
16624 (bidi_level_of_next_char): Don't try to lookup the cache for the
16625 next/previous character if nothing is cached there yet, or if we
16626 were just reseat()'ed to a new position.
16628 * xdisp.c (set_cursor_from_row): Set start and stop points
16629 according to the row's direction when priming the loop that looks
16630 for the glyph on which to display cursor.
16631 (single_display_spec_intangible_p): Function deleted.
16632 (display_prop_intangible_p): Reimplement to call
16633 handle_display_spec instead of single_display_spec_intangible_p.
16634 Accept 3 additional arguments needed by handle_display_spec.
16635 This fixes incorrect cursor motion across display property with complex
16636 values: lists, `(when COND...)' forms, etc.
16637 (single_display_spec_string_p): Support property values that are
16638 lists with the argument STRING its top-level element.
16639 (display_prop_string_p): Fix the condition for processing a
16640 property that is a list to be consistent with handle_display_spec.
16641 (handle_display_spec): New function, refactored from the
16642 last portion of handle_display_prop.
16643 (compute_display_string_pos): Accept additional argument
16644 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
16645 value of a `display' property is a "replacing spec".
16646 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
16647 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
16648 the display property, but just return a value indicating whether
16649 the display property will replace the characters it covers.
16650 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
16651 frame_window_p members of struct bidi_it.
16652 (compute_display_string_pos, compute_display_string_end):
16654 (push_it): Accept second argument POSITION, where pop_it should
16655 jump to continue iteration.
16656 (reseat_1): Initialize bidi_it.disp_pos.
16658 * keyboard.c (adjust_point_for_property): Adjust the call to
16659 display_prop_intangible_p to its new signature.
16661 * dispextern.h (struct bidi_it): New member frame_window_p.
16662 (bidi_init_it): Update prototypes.
16663 (display_prop_intangible_p): Update prototype.
16664 (compute_display_string_pos, compute_display_string_end):
16665 Declare prototypes.
16666 (struct bidi_it): New members nchars and disp_pos. ch_len is now
16669 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
16671 Malloc failure behavior now depends on size of allocation.
16672 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
16673 * lisp.h: Change signatures accordingly.
16674 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
16675 All callers changed. (Bug#8762)
16677 * gnutls.c: Use Emacs's memory allocators.
16678 Without this change, the gnutls library would invoke malloc etc.
16679 directly, which causes problems on non-SYNC_INPUT hosts, and which
16680 runs afoul of improving memory_full behavior. (Bug#8761)
16681 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
16682 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
16683 xfree instead of the default malloc, realloc, free.
16684 (Fgnutls_boot): No need to check for memory allocation failure,
16685 since xmalloc does that for us.
16687 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
16688 * category.c (hash_get_category_set):
16689 * ccl.c (ccl_driver):
16690 * charset.c (Fdefine_charset_internal):

16701 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
16702 (Fsxhash, Fgethash, Fputhash, Fmaphash):
16703 * image.c (make_image, search_image_cache, lookup_image)
16704 (xpm_put_color_table_h):
16705 * lisp.h (struct Lisp_Hash_Table):
16706 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
16707 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
16708 for hashes and hash indexes, instead of 'unsigned' and 'int'.
16709 * alloc.c (allocate_vectorlike):
16710 Check for overflow in vector size calculations.
16711 * ccl.c (ccl_driver):
16712 Check for overflow when converting EMACS_INT to int.
16713 * fns.c, image.c: Remove unnecessary static decls that would otherwise
16714 need to be updated by these changes.
16715 * fns.c (make_hash_table, maybe_resize_hash_table):
16716 Check for integer overflow with large hash tables.
16717 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
16718 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
16719 (SXHASH_REDUCE): New macro.
16720 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
16721 Use it instead of discarding useful hash info with large hash values.
16722 (sxhash_float): New function.
16723 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
16724 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
16725 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
16726 Rewrite to use FIXNUM_BITS, as this simplifies things.
16727 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
16728 Adjust signatures to match updated version of code.
16729 (consing_since_gc): Now EMACS_INT, since a single hash table can
16730 use more than INT_MAX bytes.
16732 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
16734 Make it possible to build with GCC-4.6+ -O2 -flto.
16736 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
16738 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
16740 * minibuf.c (get_minibuffer, read_minibuf_unwind):
16741 Call minibuffer-inactive-mode.
16743 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
16745 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
16746 Update dependencies.
16748 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
16750 * data.c (init_data): Remove code for UTS, this system is not
16753 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
16755 Don't force ./temacs to start in terminal mode.
16757 * frame.c (make_initial_frame): Initialize faces in all cases, not
16758 only when CANNOT_DUMP is defined.
16759 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
16761 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
16763 * dispnew.c (add_window_display_history): Use const for the string
16764 pointer. Remove declaration, not needed.
16766 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
16768 Use 'inline', not 'INLINE'.
16769 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
16770 * alloc.c, fontset.c (INLINE): Remove.
16771 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
16772 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
16773 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
16774 * gmalloc.c (register_heapinfo): Use inline unconditionally.
16775 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
16777 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
16779 Make it possible to run ./temacs.
16781 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
16782 syms_of_callproc does the same thing. Remove test for
16783 "initialized", do it in the caller.
16784 * emacs.c (main): Avoid calling set_initial_environment when dumping.
16786 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
16788 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
16789 (read_minibuf): Use get_minibuffer.
16790 (syms_of_minibuf): Use DEFSYM.
16791 (Qmetadata): New var.
16792 * data.c (Qbuffer): Don't make it static.
16793 (syms_of_data): Use DEFSYM.
16795 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
16797 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
16798 (CCL_CODE_MIN): New macro.
16800 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
16802 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
16804 * eval.c (Qdebug): Now static.
16805 * lisp.h (Qdebug): Remove decl. This reverts a part of the
16806 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
16807 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
16809 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
16811 * image.c: Various fixes to ImageMagick code comments.
16812 (Fimagemagick_types): Doc fix.
16814 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
16816 Minor fixes prompted by GCC 4.6.0 warnings.
16818 * xselect.c (converted_selections, conversion_fail_tag): Now static.
16820 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
16821 (x_clipboard_manager_save_all): Move extern decl to ...
16822 * xterm.h: ... here, so that it can be checked for consistency.
16824 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
16826 * xselect.c (x_clipboard_manager_save_frame)
16827 (x_clipboard_manager_save_all): New functions.
16828 (Fx_clipboard_manager_save): Lisp function deleted.
16830 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
16831 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
16833 * xterm.h: Update prototype.
16835 2011-05-28 William Xu <william.xwl@gmail.com>
16837 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
16838 exiting (Bug#8239).
16840 2011-05-28 Jim Meyering <meyering@redhat.com>
16842 Avoid a sign-extension bug in crypto_hash_function.
16843 * fns.c (to_uchar): Define.
16844 (crypto_hash_function): Use it to convert some newly-signed
16845 variables to unsigned, to avoid sign-extension bugs. For example,
16846 without this change, (md5 "truc") would evaluate to
16847 45723a2aff78ff4fff7fff1114760e62 rather than the expected
16848 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
16849 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
16851 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
16853 Integer overflow fixes.
16855 * dbusbind.c: Serial number integer overflow fixes.
16856 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
16857 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
16858 to hold a serial number that is too large for a fixnum.
16859 (Fdbus_method_return_internal, Fdbus_method_error_internal):
16860 Check for serial numbers out of range. Decode any serial number
16861 that was so large that it became a float. (Bug#8722)
16863 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
16864 (Fdbus_call_method, Fdbus_call_method_asynchronously):
16865 Use XFASTINT rather than XUINT when numbers are nonnegative.
16866 (xd_append_arg, Fdbus_method_return_internal):
16867 (Fdbus_method_error_internal): Likewise. Also, for unsigned
16868 arguments, check that Lisp number is nonnegative, rather than
16869 silently wrapping negative numbers around. (Bug#8722)
16870 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
16873 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
16875 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
16877 ccl: Add integer overflow checks.
16878 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
16879 (IN_INT_RANGE): New macros.
16880 (ccl_driver): Use them to check for integer overflow when
16881 decoding a CCL program. Many of the new checks are whether XINT (x)
16882 fits in int; it doesn't always, on 64-bit hosts. The new version
16883 doesn't catch all possible integer overflows, but it's an
16884 improvement. (Bug#8719)
16886 * alloc.c (make_event_array): Use XINT, not XUINT.
16887 There's no need for unsigned here.
16889 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
16890 This follows up to the 2011-05-06 change that substituted uintptr_t
16891 for EMACS_INT. This case wasn't caught back then.
16893 Rework Fformat to avoid integer overflow issues.
16894 * editfns.c: Include <float.h> unconditionally, as it's everywhere
16895 now (part of C89). Include <verify.h>.
16896 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
16897 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
16898 (Fformat): Avoid the prepass trying to compute sizes; it was only
16899 approximate and thus did not catch overflow reliably. Instead, walk
16900 through the format just once, formatting and computing sizes as we go,
16901 checking for integer overflow at every step, and allocating a larger
16902 buffer as needed. Keep track separately whether the format is
16903 multibyte. Keep only the most-recently calculated precision, rather
16904 than them all. Record whether each argument has been converted to
16905 string. Use EMACS_INT, not int, for byte and char and arg counts.
16906 Support field widths and precisions larger than INT_MAX. Avoid
16907 sprintf's undefined behavior with conversion specifications such as %#d
16908 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
16909 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
16910 formatting out-of-range floating point numbers with int
16911 formats. (Bug#8668)
16913 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
16915 * data.c: Avoid integer truncation in expressions involving floats.
16916 * data.c: Include <intprops.h>.
16917 (arith_driver): When there's an integer overflow in an expression
16918 involving floating point, convert the integers to floating point
16919 so that the resulting value does not suffer from catastrophic
16920 integer truncation. For example, on a 64-bit host (* 4
16921 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
16922 Do not rely on undefined behavior after integer overflow.
16924 merge count_size_as_multibyte, parse_str_to_multibyte
16925 * character.c, character.h (count_size_as_multibyte):
16926 Rename from parse_str_to_multibyte; all uses changed.
16927 Check for integer overflow.
16928 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
16929 since it's now a duplicate of the other. This is more of
16930 a character than a buffer op, so better that it's in character.c.
16931 * fns.c, print.c: Adjust to above changes.
16933 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
16935 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
16937 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
16939 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
16940 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
16941 (x_clipboard_manager_save): Now static.
16942 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
16944 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
16945 (crypto_hash_function): Now static.
16946 Fix pointer signedness problems. Avoid unnecessary initializations.
16948 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
16950 * termhooks.h (Vselection_alist): Make it terminal-local.
16952 * terminal.c (create_terminal): Initialize it.
16954 * xselect.c: Support for clipboard managers.
16955 (Vselection_alist): Move to termhooks.h as terminal-local var.
16956 (LOCAL_SELECTION): New macro.
16957 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
16958 (symbol_to_x_atom): Remove gratuitous arg.
16959 (x_handle_selection_request, lisp_data_to_selection_data)
16960 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
16961 (x_own_selection, x_get_local_selection, x_convert_selection):
16962 New arg, specifying work frame. Use terminal-local Vselection_alist.
16963 (some_frame_on_display): Delete unused function.
16964 (Fx_own_selection_internal, Fx_get_selection_internal)
16965 (Fx_disown_selection_internal, Fx_selection_owner_p)
16966 (Fx_selection_exists_p): New optional frame arg.
16967 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
16968 (x_handle_selection_clear): Don't treat other terminals with the
16969 same keyboard specially. Use the terminal-local Vselection_alist.
16970 (x_clear_frame_selections): Use Frun_hook_with_args.
16972 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
16974 * xterm.h: Add support for those atoms.
16976 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
16978 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
16979 (converted_selections, conversion_fail_tag): New global variables.
16980 (x_selection_request_lisp_error): Free the above.
16981 (x_get_local_selection): Remove unnecessary code.
16982 (x_reply_selection_request): Args changed; handle arbitrary array
16983 of converted selections stored in converted_selections.
16984 Separate the XChangeProperty and SelectionNotify steps.
16985 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
16986 (x_convert_selection): New function.
16987 (x_handle_selection_event): Simplify.
16988 (x_get_foreign_selection): Don't ignore incoming requests while
16989 waiting for an answer; this will fail when we implement
16990 SAVE_TARGETS, and seems unnecessary anyway.
16991 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
16992 (Vx_sent_selection_functions): Doc fix.
16994 2011-05-26 Leo Liu <sdl.web@gmail.com>
16996 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
16998 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17000 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
17002 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
17003 for fringe update if it has periodic bitmap.
17004 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
17005 and fringe_bitmap_periodic_p.
17007 * fringe.c (get_fringe_bitmap_data): New function.
17008 (draw_fringe_bitmap_1, update_window_fringes): Use it.
17009 (update_window_fringes): Record periodicity of fringe bitmap in glyph
17010 row. Mark glyph row for fringe update if periodicity changed.
17012 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
17013 for fringe update unless it has periodic bitmap.
17015 2011-05-25 Kenichi Handa <handa@m17n.org>
17017 * xdisp.c (get_next_display_element): Set correct it->face_id for
17018 a static composition.
17020 2011-05-24 Leo Liu <sdl.web@gmail.com>
17023 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
17025 * fns.c (crypto_hash_function, Fsha1): New function.
17026 (Fmd5): Use crypto_hash_function.
17027 (syms_of_fns): Add Ssha1.
17029 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
17031 * gnutls.c: Remove unused macros.
17032 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
17033 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
17034 Remove macros that are defined and never used.
17035 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
17037 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17039 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
17040 (Fx_get_selection_internal): Minor cleanup.
17041 (Fx_own_selection_internal): Rename arguments for consistency with
17044 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
17046 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
17048 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17050 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
17052 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17054 * dispnew.c (scrolling_window): Don't exclude the case that the
17055 last enabled row in the desired matrix touches the bottom boundary.
17057 2011-05-21 Glenn Morris <rgm@gnu.org>
17059 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
17060 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
17061 and add some more files.
17063 2011-05-20 Eli Zaretskii <eliz@gnu.org>
17065 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
17066 report_file_error introduced by the change from 2011-05-07.
17068 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
17070 * systime.h (Time): Define only if emacs is defined.
17071 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
17072 where the include path doesn't have X11/X.h by default. See
17073 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
17075 2011-05-20 Kenichi Handa <handa@m17n.org>
17077 * composite.c (find_automatic_composition): Fix previous change.
17079 2011-05-20 Glenn Morris <rgm@gnu.org>
17081 * lisp.mk: New file, split from Makefile.in.
17082 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
17083 (shortlisp): Remove.
17084 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
17086 2011-05-19 Glenn Morris <rgm@gnu.org>
17088 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
17089 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
17090 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
17091 (lisp): Set the order to that of loadup.el.
17092 (shortlisp): Make it a copy of $lisp.
17093 (SOME_MACHINE_LISP): Remove.
17094 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
17095 Use just $shortlisp, not $SOME_MACHINE_LISP too.
17097 2011-05-18 Kenichi Handa <handa@m17n.org>
17099 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
17100 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
17101 (find_automatic_composition): Mostly rewrite for efficiency.
17103 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
17105 * makefile.w32-in: Update dependencies.
17107 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
17109 * menu.c: Include limits.h (fixes the MS-Windows build broken by
17110 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
17112 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
17114 Fix some integer overflow issues, such as string length overflow.
17116 * insdel.c (count_size_as_multibyte): Check for string overflow.
17118 * character.c (lisp_string_width): Check for string overflow.
17119 Use EMACS_INT, not int, for string indexes and lengths; in
17120 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
17121 the resulting string length overflows an EMACS_INT; instead,
17122 report a string overflow if no precision given. When checking for
17123 precision exhaustion, use a check that cannot possibly have
17124 integer overflow. (Bug#8675)
17125 * character.h (lisp_string_width): Adjust to new signature.
17127 * alloc.c (string_overflow): New function.
17128 (Fmake_string): Use it. This doesn't change behavior, but saves
17129 a few bytes and will simplify future changes.
17130 * character.c (string_escape_byte8): Likewise.
17131 * lisp.h (string_overflow): New decl.
17133 Fixups, following up to the user-interface timestamp change.
17134 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
17135 for UI timestamps, instead of unsigned long.
17136 * msdos.c (mouse_get_pos): Likewise.
17137 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
17138 * w32gui.h (Time): Define by including "systime.h" rather than by
17139 declaring it ourselves. (Bug#8664)
17141 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
17142 * image.c (clear_image_cache): Likewise.
17144 * term.c (term_mouse_position): Don't assume time_t wraparound.
17146 Be more systematic about user-interface timestamps.
17147 Before, the code sometimes used 'Time', sometimes 'unsigned long',
17148 and sometimes 'EMACS_UINT', to represent these timestamps.
17149 This change causes it to use 'Time' uniformly, as that's what X uses.
17150 This makes the code easier to follow, and makes it easier to catch
17151 integer overflow bugs such as Bug#8664.
17152 * frame.c (Fmouse_position, Fmouse_pixel_position):
17153 Use Time, not unsigned long, for user-interface timestamps.
17154 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
17155 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
17156 * keyboard.h (last_event_timestamp): Likewise.
17157 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
17158 * menu.h (xmenu_show): Likewise.
17159 * term.c (term_mouse_position): Likewise.
17160 * termhooks.h (struct input_event.timestamp): Likewise.
17161 (struct terminal.mouse_position_hook): Likewise.
17162 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
17163 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
17164 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
17165 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
17166 what it was before.
17167 * menu.h, termhooks.h: Include "systime.h", for Time.
17169 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
17170 Don't assume that the difference between two unsigned long values
17171 can fit into an integer. At this point, we know button_down_time
17172 <= event->timestamp, so the difference must be nonnegative, so
17173 there's no need to cast the result if double-click-time is
17174 nonnegative, as it should be; check that it's nonnegative, just in
17175 case. This bug is triggered when events are more than 2**31 ms
17176 apart (about 25 days). (Bug#8664)
17178 * xselect.c (last_event_timestamp): Remove duplicate decl.
17179 (x_own_selection): Remove needless cast to unsigned long.
17181 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
17182 that always fit in int. Use a sentinel instead of a counter, to
17183 avoid a temp and to allay GCC's concerns about possible int overflow.
17184 * frame.h (struct frame): Use int for menu_bar_items_used
17185 instead of EMACS_INT, since it always fits in int.
17187 * menu.c (grow_menu_items): Check for int overflow.
17189 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
17191 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
17192 Before, the code was not consistent. These values cannot exceed
17193 2**31 - 1 so there's no need to make them unsigned.
17194 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
17195 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
17196 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
17198 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
17200 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
17201 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
17202 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
17203 presumably because the widths might not match.
17205 * window.c (size_window): Avoid needless test at loop start.
17207 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
17209 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
17211 2011-05-12 Drew Adams <drew.adams@oracle.com>
17213 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
17215 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17217 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
17218 `width' to `bar_area_x' and `bar_area_width', respectively.
17219 (x_scroll_run): Take account of fringe background extension.
17221 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
17222 Rename local vars `left' and `width' to `bar_area_x' and
17223 `bar_area_width', respectively.
17224 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
17225 background extension.
17227 2011-05-10 Jim Meyering <meyering@redhat.com>
17229 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
17231 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
17233 * image.c (Finit_image_library): Return t for built-in image types,
17234 like pbm and xbm. (Bug#8640)
17236 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
17238 * w32menu.c (set_frame_menubar): Fix submenu allocation.
17240 2011-05-07 Eli Zaretskii <eliz@gnu.org>
17242 * w32console.c (Fset_screen_color): Doc fix.
17243 (Fget_screen_color): New function.
17244 (syms_of_ntterm): Defsubr it.
17246 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
17247 unlink the temporary file if Fcall_process didn't create it in the
17249 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
17250 child process will be redirected to a file specified with `:file'.
17251 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
17252 cue to call_process_cleanup not to close that handle.
17254 2011-05-07 Ben Key <bkey76@gmail.com>
17256 * makefile.w32-in: The bootstrap-temacs rule now makes use of
17257 one of two shell specific rules, either bootstrap-temacs-CMD or
17258 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
17259 to the previous implementation of the bootstrap-temacs rule.
17260 The bootstrap-temacs-CMD rule is similar to the previous
17261 implementation of the bootstrap-temacs rule except that it
17262 makes use of the ESC_CFLAGS variable instead of the CFLAGS
17265 These changes, along with some changes to nt/configure.bat,
17266 nt/gmake.defs, and nt/nmake.defs, are required to extend my
17267 earlier fix to add support for --cflags and --ldflags options
17268 that include quotes so that it works whether make uses cmd or
17271 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
17273 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
17274 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
17276 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
17277 a string. Handle both cases.
17278 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
17279 (Fdbus_register_method): Use Qinvalid_function.
17281 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
17283 * makefile.w32-in: Update dependencies.
17284 (LISP_H): Add inttypes.h and stdin.h.
17285 (PROCESS_H): Add unistd.h.
17287 2011-05-06 Eli Zaretskii <eliz@gnu.org>
17289 * lread.c: Include limits.h (fixes the MS-Windows build broken by
17290 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
17292 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
17294 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
17296 * term.c (vfatal): Remove stray call to va_end.
17297 It's not needed and the C Standard doesn't allow it here anyway.
17299 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
17300 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
17302 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
17305 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
17307 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
17309 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
17311 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
17313 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
17315 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
17316 * charset.c (Fdefine_charset_internal): Don't initialize
17317 charset.code_space[15]. The value was garbage, on hosts with
17318 32-bit int (Bug#8600).
17320 * lread.c (read_integer): Be more consistent with string-to-number.
17321 Use string_to_number to do the actual conversion; this avoids
17322 rounding errors and fixes some other screwups. Without this fix,
17323 for example, #x1fffffffffffffff was misread as -2305843009213693952.
17324 (digit_to_number): Move earlier, for benefit of read_integer.
17325 Return -1 if the digit is out of range for the base, -2 if it is
17326 not a digit in any supported base. (Bug#8602)
17328 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
17330 * dispnew.c (scrolling_window): Return 1 if we scrolled,
17331 to match comment at start of function. This also removes a
17332 GCC warning about overflow in a 32+64-bit port.
17334 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
17336 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
17337 Reported by Stefan Monnier in
17338 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
17339 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
17340 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
17342 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
17343 (EMACS_UINTPTR): Likewise, with uintptr_t.
17345 * lisp.h: Prefer 64-bit EMACS_INT if available.
17346 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
17347 on 32-bit hosts that have 64-bit int, so that they can access
17349 However, temporarily disable this change unless the temporary
17350 symbol WIDE_EMACS_INT is defined.
17352 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
17354 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
17355 This removes an assumption that EMACS_INT and long are the same
17356 width as pointers. The assumption is true for Emacs porting targets
17357 now, but we want to make other targets possible.
17358 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
17359 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
17360 In the rest of the code, change types of integers that hold casted
17361 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
17362 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
17363 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
17364 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
17365 No need to cast type when ORing.
17366 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
17367 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
17368 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
17369 assume EMACS_INT is the same width as char *.
17370 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
17371 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
17372 Remove no-longer-needed casts.
17373 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
17374 (xg_tool_bar_help_callback, xg_make_tool_item):
17375 Use EMACS_INTPTR to hold an integer
17376 that will be cast to void *; this can avoid a GCC warning
17377 if EMACS_INT is not the same width as void *.
17378 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
17379 * xdisp.c (display_echo_area_1, resize_mini_window_1):
17380 (current_message_1, set_message_1):
17381 Use a local to convert to proper width without a cast.
17382 * xmenu.c (dialog_selection_callback): Likewise.
17384 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
17385 Also, don't assume VALBITS / RAND_BITS is less than 5,
17386 and don't rely on undefined behavior when shifting a 1 left into
17388 * lisp.h (get_random): Change signature to match.
17390 * lread.c (hash_string): Use size_t, not int, for hash computation.
17391 Normally we prefer signed values; but hashing is special, because
17392 it's better to use unsigned division on hash table sizes so that
17393 the remainder is nonnegative. Also, size_t is the natural width
17394 for hashing into memory. The previous code used 'int', which doesn't
17395 retain enough info to hash well into very large tables.
17396 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
17398 * dbusbind.c: Don't possibly lose pointer info when converting.
17399 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
17400 Use XPNTR rather than XHASH, so that the high-order bits of
17401 the pointer aren't lost when converting through void *.
17403 * eval.c (Fautoload): Don't double-shift a pointer.
17405 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.

17439 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
17440 Remove unused parameter `fildes'.
17441 * process.c (read_process_output, send_process): Don't pass it.
17443 2011-05-04 Juanma Barranquero <lekktu@gmail.com>

17446 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
17447 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".

17488 * process.c: Include lisp.h before w32.h, not after.
17489 (wait_reading_process_output): Call emacs_gnutls_record_check_pending

17492 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
17494 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
17496 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
17497 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
17500 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
17502 * xterm.c (x_set_frame_alpha): Do not set property on anything

17507 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
17509 2011-05-02 Juanma Barranquero <lekktu@gmail.com>

17537 (Fcall_process_region): Ditto.
17539 2011-04-30 Eli Zaretskii <eliz@gnu.org>
17541 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
17542 rather than `XVECTOR (FOO)->size'.
17544 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
17545 inttypes.h, as a gnulib replacement is used if it not available in
17548 2011-04-21 Eli Zaretskii <eliz@gnu.org>
17550 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
17551 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
17552 of MOST_POSITIVE_FIXNUM. (Bug#8528)
17554 * coding.c (coding_alloc_by_realloc): Error out if destination
17555 will grow beyond MOST_POSITIVE_FIXNUM.
17556 (decode_coding_emacs_mule): Abort if there isn't enough place in
17557 charbuf for the composition carryover bytes. Reserve an extra
17558 space for up to 2 characters produced in a loop.

17560 charbuf for the composition carryover bytes.
17562 2011-04-21 Eli Zaretskii <eliz@gnu.org>
17564 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
17565 aborting when %lld or %lll format is passed.
17566 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
17567 %llo or %llx format is passed. (Bug#8545)

17573 produced by %s or %c overflows available buffer space. (Bug#8545)
17575 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
17577 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

17587 (command_loop_1): Run `delayed-warnings-hook'
17588 if Vdelayed_warnings_list is non-nil.
17589 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.

17592 2011-04-28 Eli Zaretskii <eliz@gnu.org>
17594 * doprnt.c (doprnt): Don't return value smaller than the buffer
17595 size if the message was truncated. (Bug#8545).
17597 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
17599 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
17600 (Fx_window_property): #if-0 the whole functions, not just the bodies.
17602 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>

17612 Improve `doprnt' and its usage. (Bug#8545)
17613 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
17614 `format_end'. Remove support for %l as a conversion specifier.
17615 Don't use xrealloc. Improve diagnostics when the %l size modifier
17616 is used. Update the commentary.
17618 * eval.c (verror): Simplify calculation of size_t.
17620 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
17623 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
17625 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
17628 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
17630 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
17631 This makes this file independent of the recent pseudovector change.
17633 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
17635 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
17637 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
17638 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
17639 Remove unused local.
17640 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
17642 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
17643 GCC 4.6.0 optimizes based on type-based alias analysis.
17644 For example, if b is of type struct buffer * and v of type struct
17645 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
17646 != &v->size, and therefore "v->size = 1; b->size = 2; return
17647 v->size;" must therefore return 1. This assumption is incorrect
17648 for Emacs, since it type-puns struct Lisp_Vector * with many other
17649 types. To fix this problem, this patch adds a new type struct
17650 vectorlike_header that documents the constraints on layout of vectors
17651 and pseudovectors, and helps optimizing compilers not get fooled
17652 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
17653 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
17654 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
17656 (XSETPVECTYPE): Rewrite in terms of new macro.
17657 (XSETPVECTYPESIZE): New macro, specifying both type and size.
17658 This is a bit clearer, and further avoids the possibility of
17659 undesirable aliasing.
17660 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
17661 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
17662 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
17663 since Lisp_Subr is a special case (no "next" field).
17664 (ASIZE): Now uses header.size rather than size.
17665 All previous uses of XVECTOR (foo)->size replaced to use this macro,
17666 to avoid the hassle of writing XVECTOR (foo)->header.size.
17667 (struct vectorlike_header): New type.
17668 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
17669 object, to help avoid aliasing.
17670 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
17671 (SUBRP): Likewise, since Lisp_Subr is a special case.
17672 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
17673 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
17674 (struct Lisp_Hash_Table): Combine first two members into a single
17675 struct vectorlike_header member. All uses of "size" and "next" members
17676 changed to be "header.size" and "header.next".
17677 * buffer.h (struct buffer): Likewise.
17678 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
17679 * frame.h (struct frame): Likewise.
17680 * process.h (struct Lisp_Process): Likewise.
17681 * termhooks.h (struct terminal): Likewise.
17682 * window.c (struct save_window_data, struct saved_window): Likewise.
17683 * window.h (struct window): Likewise.
17684 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
17685 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
17686 * buffer.c (init_buffer_once): Likewise.
17687 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
17689 * process.c (Fformat_network_address): Use local var for size,
17692 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
17694 Make the Lisp reader and string-to-float more consistent (Bug#8525)
17695 * data.c (atof): Remove decl; no longer used or needed.
17696 (digit_to_number): Move to lread.c.
17697 (Fstring_to_number): Use new string_to_number function, to be
17698 consistent with how the Lisp reader treats infinities and NaNs.
17699 Do not assume that floating-point numbers represent EMACS_INT
17700 without losing information; this is not true on most 64-bit hosts.
17701 Avoid double-rounding errors, by insisting on integers when
17702 parsing non-base-10 numbers, as the documentation specifies.
17703 * lisp.h (string_to_number): New decl, replacing ...
17704 (isfloat_string): Remove.
17705 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
17706 (read1): Do not accept +. and -. as integers; this
17707 appears to have been a coding error. Similarly, do not accept
17708 strings like +-1e0 as floating point numbers. Do not report
17709 overflow for integer overflows unless the base is not 10 which
17710 means we have no simple and reliable way to continue.
17711 Break out the floating-point parsing into a new
17712 function string_to_number, so that Fstring_to_number parses
17713 floating point numbers consistently with the Lisp reader.
17714 (digit_to_number): Move here from data.c. Make it static inline.
17715 (E_CHAR, EXP_INT): Remove, replacing with ...
17716 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
17717 (string_to_number): New function, replacing isfloat_string.
17718 This function checks for valid syntax and produces the resulting
17719 Lisp float number too. Rework it so that string-to-number
17720 no longer mishandles examples like "1.0e+". Use strtoumax,
17721 so that overflow for non-base-10 numbers is reported only when
17722 there's no portable and simple way to convert to floating point.
17724 * textprop.c (set_text_properties_1): Rewrite for clarity,
17725 and to avoid GCC warning about integer overflow.
17727 * intervals.h (struct interval): Use EMACS_INT for members
17728 where EMACS_UINT might cause problems. See
17729 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
17730 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
17731 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
17733 (offset_intervals): Tell GCC not to worry about length overflow
17734 when negating a negative length.
17736 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
17737 (overrun_check_free): Likewise.
17739 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
17740 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
17743 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
17744 (gnutls_make_error): Rename local to avoid shadowing.
17745 (gnutls_emacs_global_deinit): ifdef out; not used.
17746 (Fgnutls_boot): Use const for pointer to readonly storage.
17747 Comment out unused local. Fix pointer signedness problems.
17749 * lread.c (openp): Don't stuff size_t into an 'int'.
17750 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
17751 about possible signed overflow.
17753 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
17754 (GDK_KEY_g): Don't define if already defined.
17755 (xg_prepare_tooltip): Avoid pointer signedness problem.
17756 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
17758 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
17759 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
17761 * xfns.c (Fx_window_property): Simplify a bit,
17762 to make a bit faster and to avoid GCC 4.6.0 warning.
17763 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
17765 * fns.c (internal_equal): Don't assume size_t fits in int.
17767 * alloc.c (compact_small_strings): Tighten assertion a little.
17769 Replace pEd with more-general pI, and fix some printf arg casts.
17770 * lisp.h (pI): New macro, generalizing old pEd macro to other
17771 conversion specifiers. For example, use "...%"pI"d..." rather
17772 than "...%"pEd"...".
17773 (pEd): Remove. All uses replaced with similar uses of pI.
17774 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
17775 * alloc.c (check_pure_size): Don't overflow by converting size to int.
17776 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
17777 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
17778 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
17779 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
17780 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
17782 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
17783 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
17784 * print.c (safe_debug_print, print_object): Likewise.
17785 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
17787 Use pI instead of if-then-else-abort. Use %p to avoid casts,
17788 avoiding the 0 flag, which is not portable.
17789 * process.c (Fmake_network_process): Use pI to avoid cast.
17790 * region-cache.c (pp_cache): Likewise.
17791 * xdisp.c (decode_mode_spec): Likewise.
17792 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined

17795 (x_stop_queuing_selection_requests): Likewise.
17796 (x_get_window_property): Don't truncate byte count to an 'int'
17799 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
17800 here, since it parses constructs like leading '-' and spaces,
17801 which are not wanted; and it overflows with large numbers.
17802 Instead, simply match F[0-9]+, which is what is wanted anyway.
17804 * alloc.c: Remove unportable assumptions about struct layout.
17805 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
17806 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
17807 (allocate_vectorlike, make_pure_vector): Use the new macros,
17808 plus offsetof, to remove unportable assumptions about struct layout.
17809 These assumptions hold on all porting targets that I know of, but
17810 they are not guaranteed, they're easy to remove, and removing them
17811 makes further changes easier.
17813 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
17814 This doesn't fix a bug but makes the code clearer.
17815 (string_overrun_cookie): Now const. Use initializers that
17816 don't formally overflow signed char, to avoid warnings.
17817 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
17818 can cause Emacs to crash when string overrun checking is enabled.
17819 (allocate_buffer): Don't assume sizeof (struct buffer) is a
17820 multiple of sizeof (EMACS_INT); it need not be, if
17821 alignof(EMACS_INT) < sizeof (EMACS_INT).
17822 (check_sblock, check_string_bytes, check_string_free_list): Protoize.

17853 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
17854 "cast to pointer from integer of different size".
17856 Improve doprnt and its use in verror. (Bug#8545)
17857 * doprnt.c (doprnt): Document the set of format control sequences
17858 supported by the function. Use SAFE_ALLOCA instead of always
17861 * eval.c (verror): Don't limit the buffer size at size_max-1, that
17862 is one byte too soon. Don't use xrealloc; instead xfree and
17865 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
17867 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the

17874 docstring. Start callback support.
17875 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
17876 unless a fatal error occurred. Call gnutls_alert_send_appropriate

17937 changes in globals.h immediately force recompilation.
17938 (TAGS): Depend on $(CURDIR)/m/intel386.h and
17939 $(CURDIR)/s/ms-w32.h.

17974 * callint.c (Fcall_interactively): When displaying error message
17975 about invalid control letter, pass the character's codepoint, not

17980 codepoint of an invalid character, to avoid displaying a bogus
17983 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
17984 `error', not SYMBOL_NAME itself.
17986 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
17987 character arguments to `error'.
17989 * charset.c (check_iso_charset_parameter): Fix incorrect argument
17990 to `error' in error message about FINAL_CHAR argument. Make sure
17991 FINAL_CHAR is a character, and use %c when it is passed as
17992 argument to `error'.
17994 2011-04-23 Eli Zaretskii <eliz@gnu.org>
17996 * s/ms-w32.h (localtime): Redirect to sys_localtime.
17998 * w32.c: Include <time.h>.

18058 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
18059 by pacifying GCC about it. Maybe it's time to retire it?
18060 * xfaces.c (USG, __TIMEVAL__): Likewise.
18062 * dispextern.h (struct redisplay_interface): Rename param
18063 to avoid shadowing.
18064 * termhooks.h (struct terminal): Likewise.
18065 * xterm.c (xembed_send_message): Likewise.

18181 * nsfont.m: Fixed bugs in ns_get_family and
18182 ns_descriptor_to_entity that were caused by using free to
18183 deallocate memory blocks that were allocated by xmalloc (via
18184 xstrdup). This caused Emacs to crash when compiled with
18185 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
18186 --enable-checking=xmallocoverrun). xfree is now used to
18187 deallocate these memory blocks.

18201 (emacs_read, emacs_write): Remove check for negative size, as the
18202 Emacs source code has been audited now.
18203 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
18204 (emacs_read, emacs_write): Use it.
18205 * process.c (send_process): Adjust to the new signatures of
18206 emacs_write and emacs_gnutls_write. Do not attempt to store
18207 a byte offset into an 'int'; it might overflow.
18208 See http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00483.html

18234 2011-04-14 Paul Eggert <eggert@cs.ucla.edu>
18236 Improve C-level modularity by making more things 'static'.
18238 Don't publish debugger-only interfaces to other modules.

18660 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
18662 * charset.c (Fclear_charset_maps): Use xfree instead of free.
18664 * keyboard.c (parse_tool_bar_item): Likewise.
18665 * sound.c (sound_cleanup, alsa_close): Likewise.
18666 * termcap.c (tgetent): Likewise.
18667 * xfns.c (x_default_font_parameter): Likewise.
18668 * xsettings.c (read_and_apply_settings): Likewise.
18670 * alloc.c (overrun_check_malloc, overrun_check_realloc)
18671 (overrun_check_free): Protoize.
18673 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
18675 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
18676 since callers should never pass a negative size.
18677 Change the signature to match that of plain 'read' and 'write'; see
18678 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
18679 * lisp.h: Update prototypes of emacs_write and emacs_read.
18681 2011-04-11 Eli Zaretskii <eliz@gnu.org>
18683 * xdisp.c (redisplay_window): Don't try to determine the character
18684 position of the scroll margin if the window start point w->startp
18685 is outside the buffer's accessible region. (Bug#8468)
18687 2011-04-10 Eli Zaretskii <eliz@gnu.org>
18689 Fix write-region and its subroutines for buffers > 2GB.
18690 * fileio.c (a_write, e_write): Modify declaration of arguments and
18691 local variables to support buffers larger than 2GB.
18692 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
18694 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
18695 argument, local variables, and return value.
18697 * lisp.h: Update prototypes of emacs_write and emacs_read.
18699 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
18701 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
18703 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
18705 Fix more problems found by GCC 4.6.0's static checks.
18707 * xdisp.c (vmessage): Use a better test for character truncation.
18709 * charset.c (load_charset_map): <, not <=, for optimization,
18710 and to avoid potential problems with integer overflow.
18711 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
18712 * casetab.c (set_identity, shuffle): Likewise.
18713 * editfns.c (Fformat): Likewise.
18714 * syntax.c (skip_chars): Likewise.
18716 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
18717 This also lets GCC 4.6.0 generate slightly better loop code.
18719 * callint.c (Fcall_interactively): <, not <=, for optimization.
18720 (Fcall_interactively): Count the number of arguments produced,
18721 not the number of arguments given. This is simpler and lets GCC
18722 4.6.0 generate slightly better code.
18724 * ftfont.c: Distingish more carefully between FcChar8 and char.
18725 The previous code passed unsigned char * to a functions like
18726 strlen and xstrcasecmp that expect char *, which does not
18727 conform to the C standard.
18728 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
18729 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
18730 char * when the C standard requires it.
18732 * keyboard.c (read_char): Remove unused var.
18734 * eval.c: Port to Windows vsnprintf (Bug#8435).
18735 Include <limits.h>.
18736 (SIZE_MAX): Define if the headers do not.
18737 (verror): Do not give up if vsnprintf returns a negative count.
18738 Instead, grow the buffer. This ports to Windows vsnprintf, which
18739 does not conform to C99. Problem reported by Eli Zaretskii.
18740 Also, simplify the allocation scheme, by avoiding the need for
18741 calling realloc, and removing the ALLOCATED variable.
18743 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
18745 Remove invocations of doprnt, as Emacs now uses vsnprintf.
18746 But keep the doprint source code for now, as we might revamp it
18747 and use it again (Bug#8435).
18748 * lisp.h (doprnt): Remove.
18749 * Makefile.in (base_obj): Remove doprnt.o.
18750 * deps.mk (doprnt.o): Remove.
18752 error: Print 32- and 64-bit integers portably (Bug#8435).
18753 Without this change, on typical 64-bit hosts error ("...%d...", N)
18754 was used to print both 32- and 64-bit integers N, which relied on
18755 undefined behavior.
18756 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
18757 * lisp.h (error, verror): Mark as printf-like functions.
18758 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
18759 Report overflow in size calculations when allocating printf buffer.
18760 Do not truncate output string at its first null byte.
18761 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
18762 Truncate the output at a character boundary, since vsnprintf does not
18764 * charset.c (check_iso_charset_parameter): Convert internal
18765 character to string before calling 'error', since %c now has the
18767 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
18768 overflow when computing char to be passed to 'error'. Do not
18769 pass Lisp_Object to 'error'; pass the integer instead.
18770 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
18771 formatted with plain %d.
18773 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
18775 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
18777 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
18779 * xterm.c (x_catch_errors): Remove duplicate declaration.
18781 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
18783 * xdisp.c, lisp.h (message_nolog): Remove; unused.
18785 2011-04-10 Jim Meyering <meyering@redhat.com>
18787 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
18788 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
18789 return ssize_t not "int", and use size_t as the buffer length.
18790 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
18791 * gnutls.h: Update declarations.
18792 * process.c (read_process_output): Use ssize_t, to match.
18793 (send_process): Likewise.
18795 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
18797 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
18799 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
18801 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
18802 Use unsigned char, to match FcChar8 type definition.
18804 * xterm.c (handle_one_xevent):
18805 * xmenu.c (create_and_show_popup_menu):
18806 * xselect.c (x_decline_selection_request)
18807 (x_reply_selection_request): Avoid type-punned deref of X events.
18809 2011-04-09 Eli Zaretskii <eliz@gnu.org>
18811 Fix some uses of `int' instead of EMACS_INT.
18812 * search.c (string_match_1, fast_string_match)
18813 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
18814 (scan_buffer, find_next_newline_no_quit)
18815 (find_before_next_newline, search_command, Freplace_match)
18816 (Fmatch_data): Make some `int' variables be EMACS_INT.
18818 * xdisp.c (display_count_lines): 3rd argument and return value now
18819 EMACS_INT. All callers changed.
18820 (pint2hrstr): Last argument is now EMACS_INT.
18822 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
18823 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
18824 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
18825 (decode_coding_utf_16, decode_coding_emacs_mule)
18826 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
18827 (decode_coding_ccl, decode_coding_charset)
18828 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
18829 (decode_coding_iso_2022, decode_coding_emacs_mule)
18830 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
18831 <char_offset, last_offset>: Declare EMACS_INT.
18832 (encode_coding_utf_8, encode_coding_utf_16)
18833 (encode_coding_emacs_mule, encode_invocation_designation)
18834 (encode_designation_at_bol, encode_coding_iso_2022)
18835 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
18836 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
18838 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
18839 (encode_invocation_designation): Last argument P_NCHARS is now
18841 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
18842 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
18844 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
18847 * ccl.c (Fccl_execute_on_string): Declare some variables
18850 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
18852 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
18854 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
18856 * process.c (Fformat_network_address): Doc fix.
18858 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
18860 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
18862 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
18864 * keyboard.c (read_char): Call Lisp function help-form-show,
18865 instead of using internal_with_output_to_temp_buffer.
18866 (Qhelp_form_show): New var.
18867 (syms_of_keyboard): Use DEFSYM macro.
18869 * print.c (internal_with_output_to_temp_buffer): Function deleted.
18871 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
18873 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
18875 * process.c (Flist_processes): Remove to Lisp.
18876 (list_processes_1): Delete.
18878 2011-04-06 Eli Zaretskii <eliz@gnu.org>
18880 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
18882 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
18884 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
18886 Fix more problems found by GCC 4.6.0's static checks.
18888 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
18890 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
18892 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
18894 * xdisp.c (vmessage): Mark as a printf-like function.
18896 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
18898 * sound.c (sound_warning): Don't crash if arg contains a printf format.
18900 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
18901 printf-like functions.
18902 (tiff_load): Add casts to remove these marks before passing them
18903 to system-supplied API.
18905 * eval.c (Fsignal): Remove excess argument to 'fatal'.
18907 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
18908 This avoids several warnings with gcc -Wstrict-overflow.
18909 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
18910 directly, rather than having caller test rule sign. This avoids
18911 some unnecessary tests.
18912 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
18913 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
18914 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
18916 * xfont.c (xfont_text_extents): Remove var that was set but not used.
18917 (xfont_open): Avoid unnecessary tests.
18919 * composite.c (composition_gstring_put_cache): Use unsigned integer.
18921 * composite.h, composite.c (composition_gstring_put_cache):
18922 Use EMACS_INT, not int, for length.

18925 breaking out part of COMPOSITION_DECODE_RULE.
18926 (COMPOSITION_DECODE_RULE): Use it.
18927 * composite.c (get_composition_id): Remove unused local vars,
18928 by using the new macro.
18930 * textprop.c (set_text_properties_1): Change while to do-while,
18931 since the condition is always true at first.
18933 * intervals.c (graft_intervals_into_buffer): Mark var as used.
18934 (interval_deletion_adjustment): Return unsigned value.
18937 * process.c (list_processes_1, create_pty, read_process_output):
18938 (exec_sentinel): Remove vars that were set but not used.
18939 (create_pty): Remove unnecessary "volatile"s.
18940 (Fnetwork_interface_info): Avoid possibility of int overflow.

18947 (update_syntax_table): Use unsigned instead of int.
18949 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
18950 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
18951 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
18953 * print.c (print_error_message): Avoid int overflow.
18955 * font.c (font_list_entities): Redo for clarity,
18956 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
18958 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
18959 (font_score): Avoid potential overflow in diff calculation.
18961 * fns.c (substring_both): Remove var that is set but not used.
18962 (sxhash): Redo loop for clarity and to avoid wraparound warning.
18964 * eval.c (funcall_lambda): Rename local to avoid shadowing.
18966 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
18967 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
18968 can always succeed if overflow has undefined behavior.
18970 * search.c (boyer_moore, wordify): Remove vars set but not used.
18971 (wordify): Omit three unnecessary tests.
18973 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
18974 All callers changed. This avoids the need for an unused var.
18976 * casefiddle.c (casify_region): Remove var that is set but not used.
18978 * dired.c (file_name_completion): Remove var that is set but not used.
18980 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
18982 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
18983 (Finsert_file_contents): Remove unnecessary code checking fd.
18985 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
18986 Check for integer overflow on size calculations.
18988 * buffer.c (Fprevious_overlay_change): Remove var that is set
18991 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
18992 Remove vars that are set but not used.
18993 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
18994 (timer_check_2): Mark vars as initialized.
18996 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
18998 * image.c (lookup_image): Remove var that is set but not used.
18999 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
19001 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
19002 that are set but not used.
19004 * xfns.c (make_invisible_cursor): Don't return garbage
19005 if XCreateBitmapFromData fails (Bug#8410).
19007 * xselect.c (x_get_local_selection, x_handle_property_notify):
19008 Remove vars that are set but not used.
19010 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
19011 (make_invisible_cursor): Initialize a possibly-uninitialized variable.

19016 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
19017 Check for overflow.
19019 * xfaces.c (realize_named_face): Remove vars that are set but not used.
19020 (map_tty_color) [!defined MSDOS]: Likewise.
19022 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
19024 * coding.c: Remove vars that are set but not used.
19025 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
19026 All callers changed.
19027 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
19028 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
19029 (decode_coding_charset): Remove vars that are set but not used.
19031 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
19032 that is set but not used.
19034 * print.c (print_object): Remove var that is set but not used.
19036 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
19037 The gnulib version avoids calling malloc in the usual case,
19038 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
19039 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
19040 * filelock.c (current_lock_owner): Likewise.
19041 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
19042 * sysdep.c: Include allocator.h, careadlinkat.h.
19043 (emacs_no_realloc_allocator): New static constant.
19044 (emacs_readlink): New function.
19045 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
19046 ../lib/careadlinkat.h.
19048 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
19050 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
19051 first non-nil return value).
19053 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
19055 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
19056 if not defined (Bug#8403).

19060 * xdisp.c (display_count_lines): Remove parameter `start',
19061 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.

19065 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
19066 and thereabouts. All callers changed.
19067 (get_per_char_metric): Remove parameter `f', unused since
19068 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
19070 2011-04-02 Jim Meyering <meyering@redhat.com>
19072 do not dereference NULL upon failed strdup
19073 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
19074 (ns_get_family): Likewise.
19076 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
19078 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
19080 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
19082 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or

19115 (Fcommandp): Handle closures.
19116 (Feval): New `lexical' arg.
19117 (eval_sub): New function extracted from Feval. Use it almost
19118 everywhere where Feval was used. Look up vars in lexical env.
19120 (Ffunctionp): Move from subr.el.
19121 (Ffuncall): Handle closures.
19122 (apply_lambda): Remove `eval_flags'.
19123 (funcall_lambda): Handle closures and new byte-code-functions.
19124 (Fspecial_variable_p): New function.
19125 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
19126 but without exporting it to Lisp.
19128 * doc.c (Fdocumentation, store_function_docstring):
19129 * data.c (Finteractive_form): Handle closures.
19131 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
19134 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
19136 (exec_byte_code): New function extracted from Fbyte_code to handle new
19137 calling convention for byte-code-functions. Add new byte-codes.
19139 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
19141 * alloc.c (Fmake_symbol): Init new `declared_special' field.
19143 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
19145 * xdisp.c (redisplay_internal): Fix prototype.
19147 2011-03-31 Eli Zaretskii <eliz@gnu.org>
19149 * xdisp.c (SCROLL_LIMIT): New macro.
19150 (try_scrolling): Use it when setting scroll_limit.
19151 Limit scrolling to 100 screen lines.
19152 (redisplay_window): Even when falling back on "recentering",
19153 position point in the window according to scroll-conservatively,
19154 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
19156 (try_scrolling): When point is above the window, allow searching
19157 as far as scroll_max, or one screenful, to compute vertical
19158 distance from PT to the scroll margin position. This prevents
19159 try_scrolling from unnecessarily failing when
19160 scroll-conservatively is set to a value slightly larger than the
19161 window height. Clean up the case of PT below the margin at bottom
19162 of window: scroll_max can no longer be INT_MAX. When aggressive
19163 scrolling is in use, don't let point enter the opposite scroll
19164 margin as result of the scroll.
19165 (syms_of_xdisp) <scroll-conservatively>: Document the
19166 threshold of 100 lines for never-recentering scrolling.
19168 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
19170 * dispextern.h (move_it_by_lines):
19171 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
19172 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
19173 (message_log_check_duplicate): Remove parameters `prev_bol' and
19174 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
19175 (redisplay_internal): Remove parameter `preserve_echo_area',
19176 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
19178 * indent.c (Fvertical_motion):
19179 * window.c (window_scroll_pixel_based, Frecenter):
19180 Don't pass `need_y_p' to `move_it_by_lines'.
19182 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
19184 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
19185 steal a few bits to be more compact.
19186 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
19187 Remove unneeded casts.
19189 * bytecode.c (Fbyte_code): CAR and CDR can GC.
19191 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
19193 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
19194 binding" message (bug#7967).
19196 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
19198 Fix more problems found by GCC 4.6.0's static checks.
19200 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
19201 Remove unused local var.
19203 * editfns.c (Fmessage_box): Remove unused local var.
19205 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
19206 (note_mode_line_or_margin_highlight, note_mouse_highlight):
19207 Omit unused local vars.
19208 * window.c (shrink_windows): Omit unused local var.
19209 * menu.c (digest_single_submenu): Omit unused local var.
19210 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
19211 Omit unused local var.
19213 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
19214 Don't assume string length fits in int.
19215 (keyremap_step, read_key_sequence): Use size_t for sizes.
19216 (read_key_sequence): Don't check last_real_key_start redundantly.
19218 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
19219 instead of alloca (Bug#8344).
19221 * eval.c (Fbacktrace): Don't assume nargs fits in int.
19222 (Fbacktrace_frame): Don't assume nframes fits in int.
19224 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
19226 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
19229 * term.c (produce_glyphless_glyph): Remove unnecessary test.
19231 * cm.c (calccost): Turn while-do into do-while, for clarity.
19233 * keyboard.c (syms_of_keyboard): Use the same style as later
19234 in this function when indexing through an array. This also
19235 works around GCC bug 48267.
19237 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
19239 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
19241 * chartab.c (sub_char_table_ref_and_range): Redo for slight
19242 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
19244 * keyboard.c, keyboard.h (num_input_events): Now size_t.
19245 This avoids undefined behavior on integer overflow, and is a bit
19246 more convenient anyway since it is compared to a size_t variable.
19248 Variadic C functions now count arguments with size_t, not int.
19249 This avoids an unnecessary limitation on 64-bit machines, which
19250 caused (substring ...) to crash on large vectors (Bug#8344).
19251 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
19252 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
19253 All variadic functions and their callers changed accordingly.
19254 (struct gcpro.nvars): Now size_t, not int. All uses changed.
19255 * data.c (arith_driver, float_arith_driver): Likewise.
19256 * editfns.c (general_insert_function): Likewise.
19257 * eval.c (struct backtrace.nargs, interactive_p)
19258 (internal_condition_case_n, run_hook_with_args, apply_lambda)
19259 (funcall_lambda, mark_backtrace): Likewise.
19260 * fns.c (concat): Likewise.
19261 * frame.c (x_set_frame_parameters): Likewise.
19262 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
19263 0 if not found, not -1. All callers changed.
19265 * alloc.c (garbage_collect): Don't assume stack size fits in int.
19266 (stack_copy_size): Now size_t, not int.
19267 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
19269 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
19271 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
19272 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
19273 All callers changed.
19275 * lisp.h (multibyte_char_to_unibyte):
19276 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
19277 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
19278 * character.h (CHAR_TO_BYTE8):
19279 * cmds.c (internal_self_insert):
19280 * editfns.c (general_insert_function):
19281 * keymap.c (push_key_description):
19282 * search.c (Freplace_match):
19283 * xdisp.c (message_dolog, set_message_1): All callers changed.
19285 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
19287 * keyboard.c (safe_run_hook_funcall): New function.
19288 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
19289 don't set the hook to nil, but remove the offending function instead.
19290 (Qcommand_hook_internal): Remove, unused.
19291 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
19292 Vcommand_hook_internal.
19294 * eval.c (enum run_hooks_condition): Remove.
19295 (funcall_nil, funcall_not): New functions.
19296 (run_hook_with_args): Call each function through a `funcall' argument.
19297 Remove `cond' argument, now redundant.
19298 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
19299 (Frun_hook_with_args_until_failure): Adjust accordingly.
19300 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
19302 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
19304 * dispextern.h (string_buffer_position): Remove declaration.
19306 * print.c (strout): Remove parameter `multibyte', unused since
19307 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
19309 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
19310 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
19311 All callers changed.
19313 * w32.c (_wsa_errlist): Use braces for struct initializers.
19315 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
19316 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
19317 All callers changed.
19318 (string_buffer_position): Likewise. Also, make static (it's never
19319 used outside xdisp.c).
19320 (cursor_row_p): Remove parameter `w', unused since
19321 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

19323 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
19324 All callers changed.
19326 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
19328 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.
19330 2011-03-27 Anders Lindgren <andlind@gmail.com>
19332 * nsterm.m (ns_menu_bar_is_hidden): New variable.
19333 (ns_constrain_all_frames, ns_menu_bar_should_be_hidden)
19334 (ns_update_auto_hide_menu_bar): New functions.
19335 (ns_update_begin): Call ns_update_auto_hide_menu_bar.
19336 (applicationDidBecomeActive): Call ns_update_auto_hide_menu_bar and
19337 ns_constrain_all_frames.
19338 (constrainFrameRect): Return at once if ns_menu_bar_should_be_hidden.
19339 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
19341 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
19343 * nsmenu.m (runDialogAt): Remove argument to timer_check.
19345 2011-03-27 Glenn Morris <rgm@gnu.org>
19347 * syssignal.h: Replace RETSIGTYPE with void.
19348 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
19349 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
19350 Replace SIGTYPE with void everywhere.
19351 * s/usg5-4-common.h (SIGTYPE): Remove definition.
19352 * s/template.h (SIGTYPE): Remove commented out definition.
19354 2011-03-26 Eli Zaretskii <eliz@gnu.org>
19356 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
19357 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
19359 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
19361 * w32.c (read_unc_volume): Use parameter `henum', instead of
19362 global variable `wget_enum_handle'.
19364 * keymap.c (describe_vector): Remove parameters `indices' and
19365 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.
19366 (describe_map, Fdescribe_vector): Adjust calls to `describe_vector'.
19368 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
19370 * keyboard.c (timer_check): Remove parameter `do_it_now',
19371 unused since 1996-04-12T06:01:29Z!rms@gnu.org.
19372 (show_help_echo): Remove parameter `ok_to_overwrite_keystroke_echo',
19373 unused since 2008-04-19T19:30:53Z!monnier@iro.umontreal.ca.
19375 * keyboard.c (read_char):
19376 * w32menu.c (w32_menu_display_help):
19377 * xmenu.c (show_help_event, menu_help_callback):
19378 Adjust calls to `show_help_echo'.
19380 * gtkutil.c (xg_maybe_add_timer):
19381 * keyboard.c (readable_events):
19382 * process.c (wait_reading_process_output):
19383 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
19385 * insdel.c (adjust_markers_gap_motion):
19386 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.
19387 (gap_left, gap_right): Don't call it.
19389 2011-03-25 Chong Yidong <cyd@stupidchicken.com>
19391 * xdisp.c (handle_fontified_prop): Discard changes to clip_changed
19392 incurred during fontification.

19433 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
19435 * w32term.c (x_set_glyph_string_clipping):
19436 Don't pass uninitialized region to CombineRgn.
19438 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
19440 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.
19441 (w32_wnd_proc): Pass NULL to Windows API, not uninitialized buffer.
19442 (Fx_close_connection): Remove unused variable `i'.
19444 * w32font.c (w32font_draw): Return number of glyphs.

19458 (uniscribe_font_driver): Add missing initializers.
19460 2011-03-23 Julien Danjou <julien@danjou.info>
19462 * term.c (Fsuspend_tty, Fresume_tty):
19463 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
19464 * window.c (temp_output_buffer_show):
19465 * insdel.c (signal_before_change):
19466 * frame.c (Fhandle_switch_frame):
19467 * fileio.c (Fdo_auto_save):
19468 * emacs.c (Fkill_emacs):
19469 * editfns.c (save_excursion_restore):
19470 * cmds.c (internal_self_insert):
19471 * callint.c (Fcall_interactively):
19472 * buffer.c (Fkill_all_local_variables):
19473 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
19475 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
19476 unconditionally since it does the check itself.
19478 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
19480 Fix more problems found by GCC 4.5.2's static checks.
19482 * coding.c (encode_coding_raw_text): Avoid unnecessary test
19483 the first time through the loop, since we know p0 < p1 then.
19484 This also avoids a gcc -Wstrict-overflow warning.
19486 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
19487 leading to a memory leak, possible in functions like
19488 load_charset_map_from_file that can allocate an unbounded number
19489 of objects (Bug#8318).
19491 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
19492 that could (at least in theory) be that large.
19494 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
19495 This is less likely to overflow, and avoids undefined behavior if
19496 overflow does occur. All callers changed. Use strtoul to scan
19497 for the unsigned long integer.
19498 (pint2hrstr): Simplify and tune code slightly.
19499 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
19501 * scroll.c (do_scrolling): Work around GCC bug 48228.
19502 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
19504 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
19505 This also avoids a warning with gcc -Wstrict-overflow.
19506 (validate_x_resource_name): Simplify count usage.
19507 This also avoids a warning with gcc -Wstrict-overflow.
19509 * fileio.c (Fcopy_file): Report error if fchown or fchmod
19512 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
19514 * process.c (Fmake_network_process): Use socklen_t, not int,
19515 where POSIX says socklen_t is required in portable programs.
19516 This fixes a porting bug on hosts like 64-bit HP-UX, where
19517 socklen_t is wider than int (Bug#8277).
19518 (Fmake_network_process, server_accept_connection):
19519 (wait_reading_process_output, read_process_output):
19522 * process.c: Rename or move locals to avoid shadowing.
19523 (list_processes_1, Fmake_network_process):
19524 (read_process_output_error_handler, exec_sentinel_error_handler):
19525 Rename or move locals.
19526 (Fmake_network_process): Define label "retry_connect" only if needed.
19527 (Fnetwork_interface_info): Fix pointer signedness.
19528 (process_send_signal): Add cast to avoid pointer signedness problem.
19529 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
19530 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
19532 Make tparam.h and terminfo.c consistent.
19533 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
19534 Include tparam.h instead, since it declares them.
19535 * cm.h (PC): Remove extern decl; tparam.h now does this.
19536 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
19537 * terminfo.c: Include tparam.h, to check interfaces.
19538 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
19539 (tparam): Adjust signature to match interface in tparam.h;
19540 this removes some undefined behavior. Check that outstring and len
19541 are zero, which they always are with Emacs.
19542 * tparam.h (PC, BC, UP): New extern decls.
19544 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
19545 (xftfont_open): Rename locals to avoid shadowing.
19547 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
19548 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.

19596 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
19598 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
19599 This should get cleaned up, so that child_setup has the
19600 same signature on all platforms.

19774 to use the following functions instead of these macros.
19775 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
19776 EMACS_INT, since callers assume the returned value fits in int.
19777 (upcase1): Likewise, for UPCASE_TABLE.
19778 (uppercasep, lowercasep, upcase): New static inline functions.
19779 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

19789 (regex_compile, re_match_2_internal): Mark locals as initialized.
19790 (RETALLOC_IF): Define only if needed.
19791 (WORDCHAR_P): Likewise. This one is never needed, but is used
19792 only in a comment talking about a compiler bug, so put inside
19793 the #if 0 of that comment.
19794 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
19795 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

19822 New macros, so that the caller can use some names other than
19823 gcpro1, gcpro2, etc.
19824 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
19826 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
19827 argument, for consistency with GCPRO2_VAR, etc: it is now the
19828 prefix of the variable, not the variable itself. All uses
19830 * dired.c (directory_files_internal, file_name_completion):
19831 Rename locals to avoid shadowing.
19833 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
19834 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
19835 dired.c's scmp function, had undefined behavior.
19836 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
19837 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
19838 * buffer.h: ... to here, because these macros use current_buffer,
19839 and the new implementation with inline functions needs to have
19840 current_buffer in scope now, rather than later when the macros
19842 (downcase, upcase1): New static inline functions.
19843 (DOWNCASE, UPCASE1): Reimplement using these functions.
19844 This avoids undefined behavior in expressions like
19845 DOWNCASE (x) == DOWNCASE (y), which previously suffered
19846 from race conditions in accessing the global variables
19847 case_temp1 and case_temp2.
19848 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
19849 * lisp.h (case_temp1, case_temp2): Remove their decls.
19850 * character.h (ASCII_CHAR_P): Move from here ...
19851 * lisp.h: ... to here, so that the inline functions mentioned
19852 above can use them.
19854 * dired.c (directory_files_internal_unwind): Now static.
19856 * fileio.c (file_name_as_directory, directory_file_name):

19859 (file_name_as_directory): Use const pointers when appropriate.
19860 (Fexpand_file_name): Likewise. In particular, newdir might
19861 point at constant storage, so make it a const pointer.

19863 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
19865 (Fset_file_times, Finsert_file_contents, auto_save_error):

19870 to avoid shadowing.
19872 * marker.c (bytepos_to_charpos): Remove; unused.
19874 * lisp.h (verify_bytepos, count_markers): New decls,
19875 so that gcc does not warn that these functions aren't declared.
19877 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
19878 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
19879 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
19880 (copy_text): Remove unused local var.
19882 * filelock.c (within_one_second): Now static.
19883 (lock_file_1): Rename local to avoid shadowing.
19885 * buffer.c (fix_overlays_before): Mark locals as initialized.
19886 (fix_start_end_in_overlays): Likewise. This function should be
19887 simplified by using pointers-to-pointers, but that's a different
19889 (switch_to_buffer_1): Now static.
19890 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
19891 (report_overlay_modification): Rename locals to avoid shadowing.

19894 Fix pointer signedness issue.
19895 (sys_subshell): Mark local as volatile if checking for lint,
19896 to suppress a gcc -Wclobbered warning that does not seem to be right.
19897 (MAXPATHLEN): Define only if needed.
19899 * process.c (serial_open, serial_configure): Move decls from here ...
19900 * systty.h: ... to here, so that they can be checked.
19902 * fns.c (get_random, seed_random): Move extern decls from here ...
19903 * lisp.h: ... to here, so that they can be checked.
19905 * sysdep.c (reset_io): Now static.
