10 (file_dialog_callback): Declared UINT_PTR.
12 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
15 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
16 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
19 2012-12-03 Glenn Morris <rgm@gnu.org>
21 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
23 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
25 Fix xpalloc confusion after memory is exhausted.
26 * alloc.c (xpalloc): Comment fix.
27 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
28 and signals an error, do not clear charset_table_size, as
29 charset_table is still valid.
30 * doprnt.c (evxprintf): Clear *BUF after freeing it.
32 Use execve to avoid need to munge environ (Bug#13054).
33 * callproc.c (Fcall_process):
34 * process.c (create_process):
35 Don't save and restore environ; no longer needed.
36 * callproc.c (child_setup):
37 Use execve, not execvp, to preserve environ.
39 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
41 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
43 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
45 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
46 display for sliced images (Bug#10500).

50 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
52 * doc.c (Fdocumentation): Re-add handling of function-documentation,
53 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
55 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
57 * xdisp.c (window_outdated): Remove eassert since it hits
58 some suspicious corner cases (see Bug#13007 and Bug#13012).
59 (mode_line_update_needed): New function.

61 (ensure_selected_frame): New function.
62 (redisplay_internal, unwind_redisplay): Use it.
63 (redisplay_internal): Move comment about buffer_shared...
64 (buffer_shared_and_changed): ...near to its real use.
66 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
68 * callproc.c (Fcall_process): Don't misreport vfork failure.
70 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
72 * callproc.c (Fcall_process): Fix vfork portability problems.
73 Do not assume that fd[0], count, filefd, and save_environ survive
74 vfork. Fix bug whereby wrong errno value could be reported for
75 pipe failure. Some minor cleanups, too, as follows. Move buf and
76 bufsize to the context where they're needed. Change new_argv to
77 be of type char **, as this is more convenient and avoids casts.
78 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
79 Now local constants, not macros.
81 2012-11-18 Kenichi Handa <handa@gnu.org>
83 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
86 2012-11-13 Kenichi Handa <handa@gnu.org>
88 * font.c (font_unparse_xlfd): Exclude special characters from the
91 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
93 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.
94 * dired.c (stat_uname, stat_gname):
95 * fileio.c (Fexpand_file_name): Remove no-longer-needed casts.
97 Assume POSIX 1003.1-1988 or later for errno.h (Bug#12968).
98 * dired.c (directory_files_internal, file_name_completion):
99 Assume EAGAIN and EINTR are defined.
101 * fileio.c (Fcopy_file): Assume EISDIR is defined.
102 * gmalloc.c (ENOMEM, EINVAL): Assume they're defined.
103 * gnutls.c (emacs_gnutls_write): Assume EAGAIN is defined.
104 * lread.c (readbyte_from_file): Assume EINTR is defined.
105 * process.c (wait_reading_process_output, send_process) [subprocesses]:
106 Assume EIO and EAGAIN are defined.
107 * unexcoff.c (write_segment): Assume EFAULT is defined.
109 2012-11-27 Eli Zaretskii <eliz@gnu.org>
111 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
114 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
115 highlighting on the frame was cleared. Prevents assertion
116 violations when repeatedly clicking on the "Top" link of the
117 "bread-crumbs" in Info buffers.
119 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>
121 * sysdep.c (sys_subshell): Don't assume pid_t fits in int.
123 2012-11-24 Ken Brown <kbrown@cornell.edu>
125 * keyboard.c (HAVE_MOUSE):
126 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
129 2012-11-24 Eli Zaretskii <eliz@gnu.org>
131 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
132 between bpos_covered and bpos_max. This fixes cursor display when
133 several display strings follow each other.
135 * .gdbinit (pgx): If the glyph's object is a string, display the
136 pointer to string data, rather than the value of the string object
137 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
139 * indent.c (Fvertical_motion): If the starting position is covered
140 by a display string, return to one position before that, to avoid
141 overshooting it inside move_it_to. (Bug#12930)
143 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
145 * frame.h (struct frame): Remove display_preempted member
146 since all users are dead long ago.
147 * nsterm.h (struct x_output): Use the only dummy member.
148 * w32menu.c (pending_menu_activation): Remove since not
150 (set_frame_menubar): Adjust user.
151 * w32term.h (struct x_output): Drop outdated #if 0 code.
152 (struct w32_output): Use bitfields for explicit_parent,
153 asked_for_visible and menubar_active members. Drop
154 unused pending_menu_activation member.
155 * xterm.h (struct x_output): Drop outdated #if 0 code.
156 Use bitfields for explicit_parent, asked_for_visible,
157 has_been_visible and net_wm_state_hidden_seen members.
159 2012-11-23 Eli Zaretskii <eliz@gnu.org>
161 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
162 of a literal "/". (Bug#12955)
163 (gl-stamp): Invoke fc.exe directly, not through cmd.
165 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
167 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
168 * dired.c: Assume HAVE_DIRENT_H.
169 (NAMLEN): Remove, replacing with ...
170 (dirent_namelen): New function. All uses changed. Use the GNU macro
171 _D_EXACT_NAMELEN if available, as it's faster than strlen.
172 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
173 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
174 * makefile.w32-in (DIR_H): Remove. All uses replaced with
176 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
177 * ndir.h: Rename to ../nt/inc/dirent.h.
178 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
179 Do not include <dirent.h>; no longer needed.
180 * w32.c: Include <dirent.h> rather than "ndir.h".
182 2012-11-23 Chong Yidong <cyd@gnu.org>
184 * xftfont.c (xftfont_open): Remove duplicate assignment.
186 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
188 * alloc.c (Fgarbage_collect): Unblock input after clearing
189 gc_in_progress to avoid note_mouse_highlight glitch with GC.
190 * frame.h (FRAME_MOUSE_UPDATE): New macro.
191 * msdos.c (IT_frame_up_to_date): Use it here...
192 * w32term.c (w32_frame_up_to_date): ...here...
193 * xterm.c (XTframe_up_to_date): ...and here...
194 * nsterm.m (ns_frame_up_to_date): ...but not here.
195 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
197 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
198 Do not check whether GC is in progress.

202 * xdisp.c (window_buffer_changed): New function.
203 (update_menu_bar, update_tool_bar): Use it to
204 simplify large 'if' statements.
205 (redisplay_internal): Generalize commonly used
206 'tail' and 'frame' local variables.
208 2012-11-22 Eli Zaretskii <eliz@gnu.org>
210 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
211 with Windows system header.
213 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
215 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
216 * alloc.c: Assume unistd.h exists.
217 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
218 * sysdep.c (get_current_dir_name): Assume getcwd exists.
219 (getwd) [USG]: Remove; no longer needed.
220 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
221 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
222 * w32.h (getcwd): Remove decl.
224 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
226 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
227 Make it set selected_window as well.
228 (update_tool_bar): Use it.
230 2012-11-21 Ken Brown <kbrown@cornell.edu>
232 * emacs.c (main): Set the G_SLICE environment variable for all
233 Cygwin builds, not just GTK builds. See
234 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
236 2012-11-21 Eli Zaretskii <eliz@gnu.org>
238 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
239 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
240 Define for the MSVC compiler.
242 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
244 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
245 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
246 dostounix_filename. Prevents crashes down the road, because
247 dostounix_filename assumes it gets a unibyte string. Reported by
248 Michel de Ruiter <michel@sentient.nl>, see
249 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
251 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
253 Conflate Qnil and Qunbound for `symbol-function'.
254 * alloc.c (Fmake_symbol): Initialize `function' to Qnil.
255 * lread.c (init_obarray): Set `function' fields to Qnil.
256 * eval.c (Fcommandp): Ignore Qunbound.
257 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
258 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
259 Test NILP rather than Qunbound.
260 (Ffmakunbound): Set to Qnil.
261 (Fsymbol_function): Never signal an error.
262 (Finteractive_form): Ignore Qunbound.
264 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
266 * eval.c (interactive_p): Remove no-longer-used decl.
268 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
270 * xdisp.c (buffer_shared): Adjust comment.
271 (buffer_shared_and_changed): New function.
272 (prepare_menu_bars, redisplay_internal): Use it to
273 decide whether all windows or frames should be updated.
274 (window_outdated): New function.
275 (text_outside_line_unchanged_p, redisplay_window): Use it.
276 (redisplay_internal): Likewise. Fix indentation.
278 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
280 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
281 (syms_of_eval): Remove corresponding defsubr.
282 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
284 2012-11-19 Daniel Colascione <dancol@dancol.org>
286 * w32fns.c (Fx_file_dialog):
287 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
288 cygwin_convert_file_name*.
290 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
291 Rename cygwin_convert_path* to cygwin_convert_file_name*.
293 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
295 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
297 2012-11-18 Eli Zaretskii <eliz@gnu.org>
299 * w32select.c: Include w32common.h before w32term.h, so that
300 windows.h gets included before w32term.h uses some of its
303 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
305 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
307 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
309 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
311 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
312 (ns_select): Return at once if events are held (Bug#12834).
314 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
316 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
317 Needed following 2012-10-20 change. (Bug#12902)
319 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
321 * w32proc.c (waitpid): Remove unused label get_result.
323 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
325 * makefile.w32-in (SYSWAIT_H): New macro.
326 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
327 ($(BLD)/sysdep.$(O)): Update dependencies.
329 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
331 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
332 * callproc.c (relocate_fd): Assume F_DUPFD.
333 * emacs.c, term.c (O_RDWR): Remove.
334 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
335 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
336 * nsterm.m: Assume <fcntl.h> exists.
337 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
338 (create_pty, Fmake_network_process, server_accept_connection)
339 (wait_reading_process_output, init_process_emacs):
341 (wait_reading_process_output): Put in a special case for WINDOWSNT
342 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
343 It's not clear this is needed, but it's a more-conservative change.
344 (create_process): Assume FD_CLOEXEC.
345 (create_process, create_pty): Assume O_NOCTTY.
346 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
347 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
348 Omit if not DOS_NT, since F_GETFL is not defined there.
349 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
350 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
352 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
353 lack it, since gnulib guarantees this.
354 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
356 2012-11-17 Eli Zaretskii <eliz@gnu.org>
358 * w32.c (faccessat): Pretend that directories have the execute bit
359 set. Emacs expects that, e.g., in files.el:cd-absolute.
361 * w32proc.c (create_child): Don't clip the PID of the child
362 process to fit into an Emacs integer, as this is no longer a
364 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
365 reaping only the process specified by PID argument, if that is
366 positive. Use PID instead of dead_child to know which process to
367 reap. Wait for the child to die only if WNOHANG is not in
369 (sys_select): Don't set dead_child.
371 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
372 as it is no longer needed.
374 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
376 (record_child_status_change): Remove the setting of
377 record_at_most_one_child for the !WNOHANG case.
379 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
381 Fix problems in ns port found by static checking.
382 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
383 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
384 not to process group.
385 (ns_select): Use emacs_write, not write, as that's more robust
386 in the presence of signals.
387 (fd_handler:): Check for read errors.
389 2012-11-16 Glenn Morris <rgm@gnu.org>
391 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
393 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
395 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
397 2012-11-16 Eli Zaretskii <eliz@gnu.org>
399 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
400 use the same value of thread handle.
401 (start_timer_thread): If the timer thread exited (due to error),
402 clean up by closing the two handles it used. Duplicate the caller
403 thread's handle here, so it gets duplicated only once, when
404 launching the timer thread. Set priority of the timer thread, not
406 (getitimer): Don't duplicate the caller thread's handle here.
409 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
411 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
414 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
416 Remove no-longer-used pty_max_bytes variable.
417 * process.c (pty_max_bytes): Remove; unused.
418 (send_process): Do not set it.
420 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
422 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
425 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
427 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
428 This follows up on the 2012-09-29 patch that removed indirection
429 for the 'function' field. Reported by Sergey Vinokurov in
430 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
432 2012-11-14 Eli Zaretskii <eliz@gnu.org>
434 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
435 different name, as the MS runtime does not have such a function,
436 and probably never will.) All callers changed. Ignore DIRFD
437 value if PATH is an absolute file name, to match Posix spec
438 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
441 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
443 * xdisp.c (echo_area_display, redisplay_internal):
444 Omit redundant check whether frame_garbaged is set.
446 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
448 Use faccessat, not access, when checking file permissions (Bug#12632).
449 This fixes a bug that has been present in Emacs since its creation.
450 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
451 which must set some sort of record. (Torek's bug report was against
452 a predecessor of GNU Emacs, but GNU Emacs happened to have the
453 same common flaw.) See Torek's Usenet posting
454 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
455 Posted: Fri Apr 8 14:18:56 1983.
456 * Makefile.in (LIB_EACCESS): New macro.
458 * callproc.c (init_callproc):
459 * charset.c (init_charset):
460 * fileio.c (check_existing, check_executable, check_writable)
462 * lread.c (openp, load_path_check):
463 * process.c (allocate_pty):
465 Use effective UID when checking permissions, not real UID.
466 * callproc.c (init_callproc):
467 * charset.c (init_charset):
468 * lread.c (load_path_check, init_lread):
469 Test whether directories are accessible, not merely whether they exist.
470 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
471 * fileio.c (check_existing, check_executable, check_writable)
473 Use symbolic names instead of integers for the flags, as they're
475 (check_writable): New arg AMODE. All uses changed.
476 Set errno on failure.
477 (Ffile_readable_p): Use faccessat, not stat + open + close.
478 (Ffile_writable_p): No need to call check_existing + check_writable.
479 Just call check_writable and then look at errno. This saves a syscall.
480 dir should never be nil; replace an unnecessary runtime check
481 with an eassert. When checking the parent directory of a nonexistent
482 file, check that the directory is searchable as well as writable, as
483 we can't create files in unsearchable directories.
484 (file_directory_p): New function, which uses 'stat' on most platforms
485 but faccessat with D_OK (for efficiency) if WINDOWSNT.
486 (Ffile_directory_p, Fset_file_times): Use it.
487 (file_accessible_directory_p): New function, which uses a single
488 syscall for efficiency.
489 (Ffile_accessible_directory_p): Use it.
490 * xrdb.c (file_p): Use file_directory_p.
491 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
492 * lread.c (openp): When opening a file, use fstat rather than
493 stat, as that avoids a permissions race. When not opening a file,
494 use file_directory_p rather than stat.
495 (dir_warning): First arg is now a usage string, not a format.
496 Use errno. All uses changed.
497 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
498 that merely introduced a race.
499 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
500 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
501 and similarly for the other O_* flags.
502 * w32.c (sys_faccessat): Rename from sys_access and switch to
503 faccessat's API. All uses changed.
504 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
505 (magic_db): Rename from magic_file_p.
506 (magic_db, search_magic_path): Return an XrmDatabase rather than a
507 char *, so that we don't have to test for file existence
508 separately from opening the file for reading. This removes a race
509 fixes a permission-checking problem, and simplifies the code.
511 (file_p): Remove; no longer needed.
513 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>

526 passed to pint2str and pint2hrstr to be at most the size of the
527 frame's decode_mode_spec_buffer. This avoids crashes with very
528 large values of FIELD_WIDTH argument to decode_mode_spec.
531 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
533 Fix a race with verify-visited-file-modtime (Bug#12863).
534 Since at least 1991 Emacs has ignored an mtime difference of no
535 more than one second, but my guess is that this was to work around
536 file system bugs that were fixed long ago. Since the race is
537 causing problems now, let's remove that code.
538 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
539 whose time stamp is off by no more than a second. Insist that the
540 file time stamps match exactly.
542 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
544 * frame.h (struct frame): Convert external_tool_bar member to
545 1-bit unsigned bitfield.
546 * termhooks.h (struct terminal): Remove mouse_moved member since
547 all users are long dead. Adjust comment on mouse_position_hook.
549 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
551 Simplify by using FOR_EACH_FRAME here and there.
552 * frame.c (next_frame, prev_frame, other_visible_frames)

560 * xmenu.c (menubar_id_to_frame): Likewise.
561 * xselect.c (frame_for_x_selection): Likewise.
562 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
563 (x_window_to_menu_bar): Likewise.
564 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
566 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
568 * data.c (Qdefalias_fset_function): Now static.
570 Another tweak to vectorlike_header change.

572 Remove, and replace all uses with ...
573 (next_in_free_list, set_next_in_free_list):
574 New functions, which respect C's aliasing rules better.
576 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
578 * window.c (list4i): Rename from 'quad'. All uses changed.
579 Needed because <sys/types.h> defines 'quad' on Solaris 10.
581 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
583 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
584 warning about mixing declarations and code in ISO C90.
586 2012-11-10 Martin Rudalics <rudalics@gmx.at>
588 * window.c (Fsplit_window_internal): Set combination limit of
589 new parent window to t iff Vwindow_combination_limit is t;
590 fixing a regression introduced with the change from 2012-09-22.
591 (Fset_window_combination_limit): Fix doc-string.
593 2012-11-10 Eli Zaretskii <eliz@gnu.org>
595 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
596 amount when the scroll margins are too large. When scrolling
597 backwards in the buffer, give up if cannot reach point or the
598 scroll margin within a reasonable number of screen lines.
599 Fixes point position in window under scroll-up/down-aggressively when
600 point is positioned many lines beyond the window top/bottom.
603 * ralloc.c (relinquish): If real_morecore fails to return memory
604 to the system, don't crash; instead, leave the last heap
605 unchanged and return. (Bug#12774)
607 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
609 * lisp.h (AUTOLOADP): New macro.
610 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
611 * data.c (Ffset): Remove special ad-advice-info handling.
612 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
614 (Finteractive_form): Simplify.

631 * w32term.c (x_scroll_bar_create): Use VECSIZE.
633 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
635 Tweak last vectorlike_header change.
636 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
637 vectorlike object on the free list. This is introduced to avoid
638 some (but not all) pointer casting and aliasing problems, see
639 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
640 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike

646 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
647 been removed, so remove them here also.
649 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
651 * doc.c (Fdocumentation): Handle new property
652 dynamic-docstring-function to replace the old ad-advice-info.

669 * lisp.h (sxhash_combine): New inline function, with the contents
670 of the old SXHASH_COMBINE.
671 * profiler.c (hashfn_profiler): Use it, instead of having a
672 special hash function containing a comparison that always yields 1.
674 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
676 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
677 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)

681 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
683 * image.c (xpm_make_color_table_h): Fix compiler error because
684 make_hash_table changed.
686 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
688 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).

772 * keyboard.c (event_to_kboard): Do not dereference
773 frame_or_window field of SELECTION_REQUEST_EVENT
774 and SELECTION_CLEAR_EVENT events (Bug#12814).
775 * xterm.h (struct selection_input_event): Adjust comment.
777 2012-11-07 Eli Zaretskii <eliz@gnu.org>
779 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
780 such as Scroll Lock, if the respective keys are treated as
781 function keys, not as modifiers. This avoids destroying non-ASCII
782 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
784 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
786 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
788 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
790 Restore some duplicate definitions (Bug#12814).
791 This undoes part of the 2012-11-03 changes. Some people build
792 with plain -g rather than with -g3, and they need the duplicate
793 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
794 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
795 Define as macros, as well as as enums or as constants.

799 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
800 to keypad keys (Bug#12816).
802 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
804 Minor adjustments of recently-changed frame functions.
805 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
806 known to be a frame (we're in the FRAMEP branch).
807 * lisp.h (Qframep): Remove decl. frame.h declares this.
808 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
809 since they're meant for Lisp fixnum values.
811 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
813 * window.c (Fwindow_combination_limit): Revert to the only
814 required argument and adjust docstring as suggested in

860 (Fwindow_fringes): Use list3.
861 (Fwindow_scroll_bars): Use list4.
862 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
863 (Fwindow_combination_limit): Allow zero number of arguments.
865 2012-11-05 Eli Zaretskii <eliz@gnu.org>
867 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
869 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
870 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
871 file descriptor 2 for standard error. (Bug#12805)
873 2012-11-05 Chong Yidong <cyd@gnu.org>
875 * process.c (wait_reading_process_output): Revert previous change.
877 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
879 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
880 This removes code that has been obsolete since around 1990.
881 * callproc.c (Fcall_process):
883 * process.c (create_process):
884 * term.c (dissociate_if_controlling_tty):
885 Assume setsid exists.
886 * callproc.c (child_setup): Assume setpgid exists and behaves as
887 per POSIX.1-1988 or later.
888 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
889 * emacs.c (shut_down_emacs):
890 * sysdep.c (sys_suspend, init_foreground_group):

892 * msdos.c (setpgrp): Remove.
893 (tcgetpgrp, setpgid, setsid): New functions.
894 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.

904 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
906 Remove EMACS_OUTQSIZE+sleep hack.
907 * dispnew.c (update_frame_1): Remove hack for terminals slower
908 than 2400 bps, which throttled Emacs by having it sleep.
909 This code hasn't worked since at least 2007, when the multi-tty stuff
910 was added, and anyway those old terminals are long dead.
911 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
912 without the dispnew.c change, as dispnew.c doesn't include systty.h.
914 Fix data-loss with --version (Bug#9574).
915 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
916 as we can't assume that emacs_strerror is initialized, and strerror
918 (main): Invoke atexit earlier, to catch earlier instances of
919 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
921 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
923 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).

926 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
928 Fix data-loss with --batch (Bug#9574).
929 * emacs.c: Include <close-stream.h>.
930 (close_output_streams): New function.
931 (main): Pass it to atexit, so that Emacs closes stdout and stderr
932 and handles errors appropriately.
933 (Fkill_emacs): Don't worry about flushing, as close_output_stream
936 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
937 The symptom is a diagnostic "GLib-WARNING **: In call to
938 g_spawn_sync(), exit status of a child process was requested but
939 SIGCHLD action was set to SIG_IGN and ECHILD was received by
940 waitpid(), so exit status can't be returned." The diagnostic
941 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
942 The real bug is a race condition between Emacs and glib: Emacs
943 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
944 so that glib can't find it. Work around the bug by invoking
945 waitpid only on subprocesses that Emacs itself creates.
946 * process.c (create_process, record_child_status_change):
947 Don't use special value -1 in pid field, as the caller now must
948 know the pid rather than having the callee infer it.
949 The inference was sometimes incorrect anyway, due to another race.
950 (create_process): Set new 'alive' member if child is created.
951 (process_status_retrieved): New function.
952 (record_child_status_change): Use it.
953 Accept negative 1st argument, which means to wait for the
954 processes that Emacs already knows about. Move special-case code
955 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
956 processes that have already been waited for, by testing and
957 clearing new 'alive' member.
958 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
959 now does this internally.
960 (handle_child_signal): Let record_child_status_change do all
961 the work, since we do not want to reap all exited child processes,
962 only the child processes that Emacs itself created.
963 * process.h (Lisp_Process): New boolean member 'alive'.
965 Omit duplicate definitions no longer needed with gcc -g3.
966 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
967 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
968 Define only as macros. There's no longer any need to also define
969 these symbols as enums or as constants, since we now assume
970 gcc -g3 when debugging.
972 2012-11-03 Eli Zaretskii <eliz@gnu.org>
974 * lisp.mk: Adjust comments to the fact that term/internal is now
975 loaded from loadup.el.
977 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
978 (msdos_fatal_signal): New function.
979 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
982 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
983 for GCC versions before 4.
984 (emacs_raise): Define to call msdos_fatal_signal.
986 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
987 iterator when starting in the middle of a display or overlay
990 2012-11-03 Chong Yidong <cyd@gnu.org>
992 * process.c (wait_reading_process_output): Clean up the last
995 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
997 * process.c (wait_reading_process_output): Avoid a race condition
998 with SIGIO delivery (Bug#11536).
1000 2012-11-03 Chong Yidong <cyd@gnu.org>
1002 * buffer.c (cursor_type): Untabify docstring.
1004 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1006 * frame.h (struct frame): Drop can_have_scroll_bars member
1007 which is meaningless for a long time. Adjust comments.
1008 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
1009 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
1011 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1013 * window.c (decode_next_window_args): Update window arg after
1014 calling decode_live_window and so fix crash reported at
1015 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
1016 by Juanma Barranquero <lekktu@gmail.com>.
1017 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
1018 * font.c (Ffont_at): Likewise.
1020 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>

1031 (BACKTRACE_LIMIT_MAX): New macro.
1032 (w32_backtrace): New function.
1033 (emacs_abort): Use w32_backtrace when the user chooses not to
1034 attach a debugger. Update the text of the abort dialog.
1036 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1038 Window-related stuff cleanup here and there.
1039 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
1040 Use decode_any_window.
1041 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
1042 * xdisp.c (Fformat_mode_line): Likewise.
1043 * font.c (Ffont_at): Use decode_live_window.
1044 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.

1046 (decode_any_window): Remove static.
1047 * window.h (decode_any_window): Add prototype.
1048 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
1049 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
1052 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1054 Remove pad from struct input_event.
1055 * termhooks.h (struct input_event): Remove padding field.
1057 * keyboard.c (event_to_kboard): Simplify because frame_or_window
1058 member is never cons for a long time. Adjust comment.
1059 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
1060 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
1061 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
1062 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
1064 2012-11-01 Eli Zaretskii <eliz@gnu.org>
1066 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
1068 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
1070 Fix crash when using Emacs as commit editor for git (Bug#12697).
1071 * callproc.c (setpgrp): Remove macro, as we now use setpgid
1072 and it is configured in conf_post.h.
1073 (Fcall_process): Don't invoke both setsid and setpgid; the former
1074 is enough, if it exists.
1075 * callproc.c (Fcall_process, child_setup):
1076 * process.c (create_process): Use setpgid.
1077 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
1079 * dispnew.c (init_display): Initialize the foreground group
1080 if we are running a tty display.
1081 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
1082 * lisp.h (init_foreground_group): New decl.
1083 * sysdep.c (inherited_pgroup): New static var.
1084 (init_foreground_group, tcsetpgrp_without_stopping)
1085 (narrow_foreground_group, widen_foreground_group): New functions.
1086 (init_sys_modes): Narrow foreground group.
1087 (reset_sys_modes): Widen foreground group.
1089 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
1091 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
1093 2012-10-31 Martin Rudalics <rudalics@gmx.at>
1095 * minibuf.c (read_minibuf): Restore current buffer since
1096 choose_minibuf_frame calling Fset_frame_selected_window may
1097 change it (Bug#12766).
1099 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
1101 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
1103 2012-10-30 Kenichi Handa <handa@gnu.org>
1105 * font.c (Ffont_at): If WINDOW is specified and it is not
1106 displaying the current buffer, signal an error.
1108 2012-10-29 Daniel Colascione <dancol@dancol.org>
1110 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
1111 In preparation for fixing bug#12739, move these functions from
1114 * coding.h, coding.c: ... to here, and compile them only when
1115 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
1116 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
1118 2012-10-28 Eli Zaretskii <eliz@gnu.org>
1120 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
1121 (timer_loop, getitimer, setitimer): Use it instead of
1122 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
1124 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
1127 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
1129 * nsterm.m (NO_APPDEFINED_DATA): New define.

1131 (last_appdefined_event): Remove.
1132 (ns_select): Initialize t from last_appdefined_event_data instead
1133 of [last_appdefined_event data1].
1134 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
1135 remove last_appdefined_event (Bug#12698).
1137 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
1139 * frame.c (x_set_font): Catch internal error.
1141 2012-10-27 Eli Zaretskii <eliz@gnu.org>
1143 Avoid overflow in w32 implementation of interval timers.
1144 When possible, for ITIMER_PROF count only times the main thread
1146 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
1147 'volatile ULONGLONG' types. All the other data which was
1148 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
1149 (GetThreadTimes_Proc): New typedef.
1150 (w32_get_timer_time): New function, returns a suitable time value
1152 (timer_loop): Enter critical section when accessing ULONGLONG
1153 values of the itimer_data struct, as these accesses are no longer
1154 atomic. Call 'w32_get_timer_time' instead of 'clock'.
1155 Remove unused variable.
1156 (init_timers): Initialize s_pfn_Get_Thread_Times.
1157 (start_timer_thread): Don't assign itimer->caller_thread here.
1158 (getitimer): Assign itimer->caller_thread here.

1164 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
1165 mouse movement events if the menu bar is active. This avoids
1166 producing a busy "hour-glass" cursor by Windows if the mouse
1167 pointer is positioned over a tooltip shown for some menu item.
1169 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
1171 Don't assume process IDs fit in int.
1172 * emacs.c (shut_down_emacs) [!DOS_NT]:
1173 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
1174 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
1175 Use pid_t, not int, to store process IDs, as 'int'
1176 is not wide enough on a few platforms (e.g., AIX and IRIX).
1178 2012-10-23 Kenichi Handa <handa@gnu.org>
1180 The following change is to make face-font-rescale-alist work
1181 correctly for non-ASCII fonts.
1183 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
1184 (font_open_for_lface): Handle Vface_font_rescale_alist.
1186 2012-10-23 Chong Yidong <cyd@gnu.org>
1188 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.

1199 2012-10-21 Glenn Morris <rgm@gnu.org>
1201 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
1203 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
1205 Port to OpenBSD 5.1.
1206 * frame.c (Fmouse_position, Fmouse_pixel_position):
1207 * xdisp.c (produce_stretch_glyph):
1208 Declare local vars only when they're needed.
1209 This is clearer and avoids a warning on OpenBSD about unused vars.
1210 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
1211 This is safer, and avoids OpenBSD warnings about unused vars.
1212 * keyboard.c (record_menu_key): Remove unnecessary decl.
1213 (poll_timer): Define only if POLL_FOR_INPUT is defined.
1214 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
1215 as our definition clashes with OpenBSD's.
1216 * xfaces.c (load_face_colors, check_lface_attrs)
1217 (get_lface_attributes_no_remap, get_lface_attributes)
1218 (lface_fully_specified_p, x_supports_face_attributes_p)
1219 (tty_supports_face_attributes_p, face_fontset, realize_face)
1220 (realize_x_face, realize_tty_face):
1221 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
1222 merely Lisp_Object *. This is more informative and avoids
1223 a warning on OpenBSD about accessing beyond an object's size.
1225 2012-10-20 Chong Yidong <cyd@gnu.org>
1227 * lread.c (Fload): Doc fix (Bug#12592).
1229 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
1231 * font.c (Ffont_at): Fix previous change.
1233 2012-10-19 Eli Zaretskii <eliz@gnu.org>
1235 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
1236 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html

1249 FD_ISSET (Bug#12668).
1251 2012-10-18 Daniel Colascione <dancol@dancol.org>
1253 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
1254 (staticpro): If we run out of staticpro slots, die with an
1255 informative error instead of just calling emacs_abort.
1257 2012-10-18 Martin Rudalics <rudalics@gmx.at>
1259 Fix two flaws reported by Dmitry Antipov.
1260 * window.c (Ftemp_output_buffer_show): Remove.

1302 Lisp_Object values. (Bug#12661)
1304 * w32fns.c (w32_msg_pump): Use XIL instead of casting an integer
1305 to Lisp_Object. (Bug#12661)

1379 Fix some stat-related races.
1380 * fileio.c (Fwrite_region): Avoid race condition if a file is
1381 removed or renamed by some other process immediately after Emacs
1382 writes it but before Emacs stats it. Do not assume that stat (or
1384 * image.c (slurp_file): Resolve the file name with fopen + fstat
1385 rather than stat + fopen.

1413 * fileio.c (check_existing): New function.
1414 (make_temp_name, Ffile_exists_p, Ffile_writable_p): Call it
1415 instead of calling 'stat', when what's needed is to check whether
1416 a file exists. This avoids expensive system calls on MS-Windows.
1419 * w32.c (init_environment): Call 'check_existing' instead of 'stat'.
1421 * lread.c (openp) [WINDOWSNT]: Call 'access' instead of 'stat' to
1422 determine whether a file exists and is not a directory.
1424 * lisp.h (check_existing): Add prototype.
1426 2012-10-12 Jan Djärv <jan.h.d@swipnet.se>

1458 Use bool for booleans.
1459 * lread.c (safe_to_load_version): Rename from safe_to_load_p,

1512 * process.c (wait_reading_process_output):
1513 Use unsigned for counter where wraparound-on-overflow is desired,
1514 since unsigned is guaranteed to have that behavior and signed is not.
1515 (read_char): Use ptrdiff_t for string length.
1516 (get_input_pending): Remove first argument, since it was always
1517 the same pointer-to-int (now pointer-to-boolean) &input_pending,
1518 and behave as if it had that value. Return new value of
1519 input_pending. All callers changed.
1520 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
1521 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
1523 * keymap.c (push_key_description): Omit last arg, which was always 1.
1524 All callers changed.
1526 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.
1528 2012-10-10 Juanma Barranquero <lekktu@gmail.com>

1544 Don't include termopts.h.
1546 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
1548 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
1550 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
1552 * commands.h (immediate_quit): Remove duplicate decl.
1554 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
1556 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles

1559 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
1561 2012-10-09 Eli Zaretskii <eliz@gnu.org>
1563 * w32fns.c (w32_last_error): Change the return value to DWORD, to
1564 match what GetLastError returns. Explain why the function is
1567 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
1568 'is_tooltip_frame', to avoid confusion with its global namesake.
1570 2012-10-08 Daniel Colascione <dancol@dancol.org>
1572 * xdisp.c (start_hourglass): Call w32_note_current_window when
1573 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
1574 build that caused Emacs to display the hourglass cursor forever.
1576 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
1577 which is broken under remote desktop, calculate the number of
1578 colors available for a display based on the display's number of
1579 planes and number of bits per pixel per plane. (bug#10397).
1581 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
1583 * nsfont.m (Vfonts_in_cache): New variable.
1584 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
1585 are used. Add cached fonts to Vfonts_in_cache.
1586 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
1588 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
1590 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
1592 (FONT_H): Define after FRAME_H.
1593 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
1594 Update dependencies.
1596 * w32term.c: Remove leftover declaration of keyboard_codepage.
1598 2012-10-08 Eli Zaretskii <eliz@gnu.org>
1600 * makefile.w32-in (FONT_H): Add $(FRAME_H).
1601 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
1602 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
1603 (GLOBAL_SOURCES): Add cygw32.c.
1604 ($(BLD)/unexw32.$(O)):
1606 ($(BLD)/w32console.$(O)):
1607 ($(BLD)/w32fns.$(O)):
1608 ($(BLD)/w32heap.$(O)):
1609 ($(BLD)/w32menu.$(O)):
1610 ($(BLD)/w32proc.$(O)): Add w32common.h.
1612 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
1614 (x_to_w32_color): Don't modify the argument, modify a copy instead.
1616 2012-10-08 Daniel Colascione <dancol@dancol.org>
1618 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
1619 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
1620 accidental message numbering hole. Change other messages to
1623 * w32select.h (HAVE_W32SELECT): Remove.
1625 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
1626 w32common.h instead of w32heap.h.
1628 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
1629 (get_allocation_unit, get_processor_type, get_w32_major_version)
1630 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
1631 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
1632 (OS_NT, os_subtype, cache_system_info): Move declarations to
1635 * w32heap.c: Include w32common.h.
1636 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
1637 (w32_minor_version, w32_build_number, w32_subtype):
1638 Remove duplicate definitions.
1640 * w32fns.c: Include w32common.h; include w32heap.h only in
1643 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
1644 Use `report_file_error' instead of `error' in order to better
1645 inform users of what went wrong. Increase NTGUI_UNICODE file
1646 dialog box file name length to 32k, the maximum allowed by the NT
1649 * w32common.h: New file.
1650 (ROUND_UP, ROUND_DOWN, get_page_size)
1651 (get_allocation_unit, get_processor_type, get_w32_major_version)
1652 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
1653 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
1654 (OS_NT, os_subtype, cache_system_info): Move here.
1656 * unexw32.c, unexcw.c: Include w32common.h.
1658 * emacs.c (main): Use (defined (WINDOWSNT) || defined
1659 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
1660 to call syms_of_w32select.
1662 * cygw32.h: Remove obsolete EXFUN declarations.
1664 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
1666 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
1667 of w32inevt.o from SOME_MACHINE_OBJECTS.
1669 2012-10-08 Daniel Colascione <dancol@dancol.org>
1671 * image.c: Permanent fix for JPEG compilation issue --- limit
1672 jpeglib `boolean' redefinition to Cygwin builds.
1674 2012-10-08 Eli Zaretskii <eliz@gnu.org>
1676 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
1678 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
1681 2012-10-08 Daniel Colascione <dancol@dancol.org>
1683 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
1684 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
1685 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
1686 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
1687 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
1688 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
1689 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
1690 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
1691 now a supported configuration.
1693 * Makefile.in: consolidate image variables into LIBIMAGE; add
1694 W32_OBJ and W32_LIBS. Compile new files.
1697 (_DebPrint) declare tracing facility for W32 debugging. We need
1698 to unify tracing later.
1700 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
1701 unconditional use of W32 Unicode functions. Cygwin runs only on
1702 100% Unicode operating systems.
1704 * cygw32.c: New file. Define Cygwin-specific facilities.
1705 (Fcygwin_convert_path_to_windows)
1706 (Fcygwin_convert_path_from_windows): New user functions for
1707 accessing Cygwin path-munging routines.
1709 * cygw32.h: New file.
1710 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
1711 UTF-16LE strings temporarily inside non-Lisp-visible string
1714 (w32_strerror): Just what it says on the tin.
1716 * emacs.c: Make the NS fork-then-exec code for daemon-launching
1717 also run for Cygwin; both systems have the same problem with using
1718 GUI facilities in a forked child. Also call syms_of_cygw32,
1719 syms_of_w32select in correct places.
1721 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
1722 needs fork-then-exec for daemon launching.
1724 * font.h: Include frame.h.
1726 * image.c: Use the image library cache machinery only when we're
1727 compiling for native WINDOWSNT; Cygwin can use shared libraries
1728 like any other Unixlike system.
1730 * keyboard.c: Clarify a comment regarding the input loop.
1732 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
1733 functions directly instead of trying to detect at runtime that our
1734 host operating system supports them. We make this change for two
1735 reasons: Cygwin lacks support for the multibyte character
1736 conversion functions used by the legacy menu code, and Cygwin
1737 never needs to rely on non-Unicode APIs.
1739 * unexw32.c (hinst): Declare extern.
1741 * w32.c: Change header order;
1742 (w32_strerror): Move to w32fns.c because we need it for
1743 non-WINDOWSNT builds.
1745 * w32.h: Add #error macro to make sure we don't include w32.h for
1746 Cygwin builds. Remove w32select declarations.
1748 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
1749 w32fns.c. w32console.c is WINDOWSNT-only.
1751 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
1752 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
1754 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
1755 (w32_major_version, w32_minor_version, w32_build_number)
1756 (os_subtype, sound_type): Define here
1757 (w32_defined_color): Make color parameter const for consistency
1758 with other _defined_color functions.
1759 (w32_createwindow): Unconditionally call w32_init_class instead of
1760 doing so only when hprevinst is non-NULL. Plumbing hprevinst
1761 through the code is complex and unnecessary because class
1762 registration is practically free.
1763 (w32_name_of_message): New EMACSDEBUG-only function.
1764 (Fset_message_beep): Move here
1765 (Fx_open_connection): Require that the display name for Windows be
1766 "w32" for consistency, emacsclient disambiguation, and maybe, one
1767 day, multi-window-system support.
1768 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
1769 Cygwin files for W32 GUI facilities, since these clearly don't
1770 expect Cygwin names.
1771 (_DebPrint): Define.
1772 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
1773 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
1774 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
1775 (w32_last_error): Remove.
1777 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
1779 * w32heap.c (syspage_mask): Declare here.
1780 (cache_system_info): Remove.
1782 * w32inevt.c (faked_key): Define globally, not statically.
1783 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
1784 (w32_console_toggle_lock_key): Move to w32fns.c.
1786 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
1788 * w32proc.c (_DebPrint): Move to w32fns.c.
1789 * w32select.c: Include string.h, stdio.h for Cygwin.
1790 * w32select.h: New File.
1792 * w32term.c: Include io.h for non-CYGWIN builds; needed for
1794 (w32_message_fd): New variable. Under Cygwin, holds the file
1795 descriptor the system used to tell us about pending thread
1798 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
1799 that prevented compilation under non-WINDOWSNT systems.
1801 (w32_initialize): Open /dev/windows and assign it to
1802 w32_message_fd. Provide w32 feature.
1804 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
1805 (WM_EMACS_INPUT_READY): add.
1806 (prepend_msg, w32_message_fd): Declare globally.
1809 (keyboard_handle): Use only when WINDOWSNT.
1810 (notify_msg_ready): New function. Posts a message to the main
1811 thread's message queue under CYGWIN, which wakes up the main
1812 thread from select(2) by making the /dev/windows file descriptor
1813 ready. Under WINDOWSNT, it sets an event the same way the old
1816 (post, prepend_msg): Actually call notify_msg_ready instead of
1817 setting the input event directly.
1819 2012-10-07 Eli Zaretskii <eliz@gnu.org>
1821 * ralloc.c (relinquish): If a heap is ready to be relinquished,
1822 but it still has blocs in it, don't return it to the system,
1823 instead of aborting. (Bug#12402)
1825 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
1827 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
1829 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
1830 MAC_OS_X_VERSION_10_6.

1835 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
1837 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
1838 MAC_OS_X_VERSION_10_4.
1840 * nsmenu.m (fillWithWidgetValue:): Remove code for <
1841 MAC_OS_X_VERSION_10_2.
1843 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
1845 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
1846 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
1848 * nsterm.m (ns_in_resize): Remove (Bug#12479).
1849 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
1850 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
1851 Remove ns_in_resize check.
1852 (ns_clear_frame_area): Remove resize handle code.
1854 * nsfns.m (ns_in_resize): Remove.
1855 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
1856 Remove ns_in_resize check.
1858 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
1860 Improve sys_siglist detection.
1861 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
1862 defined as a macro, as is done in Solaris.
1863 (sys_siglist_entries): New macro.
1864 (save_strsignal): Use it.
1865 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
1866 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
1868 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
1870 * nsfns.m (Fx_create_frame): Call x_default_parameter with
1871 fullscreen/Fullscreen.
1873 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
1874 tobar_height is new.
1876 * nsterm.m (x_make_frame_visible): Check for fullscreen.
1877 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
1878 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
1879 (windowDidResize:): Check for correct window if old style fullscreen.
1880 Capitalize word in comment. Remove incorrect comment.
1881 (initFrameFromEmacs:): tbar_height renamed tibar_height.
1882 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
1883 error in drawing background.
1884 (toggleFullScreen:): Remove comment. Rearrange calls.
1885 Set toolbar values to zero, save old height in tobar_height.
1886 Restore tool bar height when leaving fullscreen.

1893 2012-10-05 Eli Zaretskii <eliz@gnu.org>
1895 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
1897 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
1898 that time stamps of directories could also be changed.
1899 Don't request the too broad GENERIC_WRITE, only the more restrictive
1900 FILE_WRITE_ATTRIBUTES access rights.
1902 * fileio.c (Fset_file_times): Special-case ignoring errors for
1903 directories only on MSDOS, not on MS-Windows.
1905 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)

1916 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
1917 to avoid similar races.
1918 * keyboard.c (pending_signals): Now bool, not int.
1920 Port timers to OpenBSD, plus check for timer failures.
1921 OpenBSD problem reported by Han Boetes.
1922 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
1924 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
1925 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
1926 like OpenBSD, which has timer_settime but does not declare it.
1927 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
1928 whether to use itimerspec-related primitives. All uses of
1929 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
1931 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
1933 * profiler.c (handle_profiler_signal): Fix a malloc race
1934 that caused Emacs to hang on Fedora 17 when profiling Lisp.

1938 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
1940 2012-10-02 Eli Zaretskii <eliz@gnu.org>
1942 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
1943 consistent with the change in return value of 'safe_strsignal'.
1945 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>

1955 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
1956 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
1957 Now 'static', not 'static inline'.
1959 Count overruns when profiling; change units to ns.
1960 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
1961 Give extra weight to samples after overruns, to attempt to count
1962 the time more accurately.
1963 (setup_cpu_timer): Change sampling interval units from ms to ns, since
1964 the underlying primitives nominally do ns.
1965 (Fprofiler_cpu_start): Document the change. Mention that
1966 the sampling intervals are only approximate.
1968 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
1970 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
1972 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
1973 case for the special 0 coding-system.
1975 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
1976 (Fmake_overlay): Remove redundant tests.
1977 (fix_start_end_in_overlays): Remove redundant recentering.
1979 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
1981 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
1982 Update dependencies.
1984 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
1986 Fix a malloc race condition involving strsignal.
1987 A signal can arrive in the middle of a malloc, and Emacs's signal
1988 handler can invoke strsignal, which can invoke malloc, which is
1989 not portable. This race condition bug makes Emacs hang on GNU/Linux.
1990 Fix it by altering the signal handler so that it does not invoke
1992 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
1993 * process.c (status_message): Use const pointer, in case strsignal
1994 is #defined to safe_strsignal.
1995 * sysdep.c (sys_siglist, init_signals): Always define and
1996 initialize a substitute sys_siglist if the system does not define
1997 one, even if HAVE_STRSIGNAL.
1998 (safe_strsignal): Rename from strsignal. Always define,
1999 using sys_siglist. Return a const pointer.
2000 * syssignal.h (safe_strsignal): New decl.
2001 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
2003 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2005 * w32proc.c (timer_loop): Fix code that waits for timer
2006 expiration, to avoid high CPU usage.
2008 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
2010 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
2011 (sweep_weak_table): Remove redundant prototypes.
2013 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
2015 * emacs.c: Move the inclusion of TERM_HEADER after including
2016 windows.h on WINDOWSNT. This avoids compilation problems with
2019 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2021 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
2022 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
2023 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
2024 as the previous version used 'void *'.
2026 * ralloc.c (ROUNDUP): Fix last change.
2027 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
2030 * w32proc.c <disable_itimers>: New static flag.
2031 (init_timers): Initialize it to zero, after creating the critical
2032 sections used by the timer threads.
2033 (term_timers): Set to 1 before deleting the critical sections.
2034 (getitimer, setitimer): If disable_itimers is non-zero, return an
2035 error indication without doing anything. Reported by Fabrice
2036 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
2037 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
2039 [!HAVE_SETITIMER]: Behave as the previous version that didn't
2042 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
2043 term_ntproc after all the other bookkeeping, to get timers working
2044 as long as possible.
2046 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2048 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
2049 Suggested by Juri Linkov in
2050 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
2052 Prefer plain 'static' to 'static inline' (Bug#12541).
2053 With static functions, modern compilers inline pretty well by
2054 themselves; advice from programmers often hurts as much as it helps.
2055 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
2056 this change shrinks the text size of the Emacs executable by 1.1%
2057 without affecting CPU significantly in my benchmark.
2058 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

2140 Revert the FOLLOW-SYMLINKS change for file-attributes.

2143 * dired.c (directory_files_internal, Ffile_attributes):

2335 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
2336 HAVE_TIMER_SETTIME is defined.
2338 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
2340 Profiler improvements: more-accurate timers, overflow checks.
2341 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
2342 signal.h, setjmp.h. Include systime.h instead.
2343 (saturated_add): New function.
2344 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.
2345 (record_backtrace, handle_profiler_signal): Saturate on fixnum overflow.
2346 (profiler_timer, profiler_timer_ok) [HAVE_TIMER_SETTIME]:
2348 (enum profiler_cpu_running): New enum.
2349 (profiler_cpu_running): Now of that enum type, not bool.
2350 All uses changed to store the new value.
2351 (handle_profiler_signal): Rename from sigprof_handler_1,
2352 for consistency with other handlers. Do not check whether
2353 cpu_log is a hash-table if garbage collecting, since it
2354 doesn't matter in that case.
2355 (deliver_profiler_signal): Rename from sigprof_handler,
2356 for consistency with other handlers.
2357 (setup_cpu_timer): New function, with much of what used to be in
2358 Fprofiler_cpu_start. Check for out-of-range argument.
2359 Prefer timer_settime if available, and prefer
2360 thread cputime clocks, then process cputime clocks, then
2361 monotonic clocks, to the old realtime clock. Use make_timeval
2362 to round more-correctly when falling back to setitimer.
2363 (Fprofiler_cpu_start): Use it.
2364 (Fprofiler_cpu_stop): Prefer timer_settime if available.
2365 Don't assume that passing NULL as the 2nd argument of setitimer
2366 is the same as passing a pointer to all-zero storage.
2367 Ignore SIGPROF afterwards.
2368 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
2369 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
2370 non-fatal signal handlers. Ignore SIGPROF on startup.
2371 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
2372 in profiler.c, since sysdep.c now uses it.
2374 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
2375 Suggested by Eli Zaretskii in
2376 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
2378 2012-09-29 Juanma Barranquero <lekktu@gmail.com>
2380 * makefile.w32-in ($(BLD)/profiler.$(O)): Update dependencies.
2382 2012-09-29 Stefan Monnier <monnier@iro.umontreal.ca>

2385 * xdisp.c (redisplay_internal):
2386 * profiler.c (record_backtrace, sigprof_handler_1):
2387 * alloc.c (Fgarbage_collect):
2388 * eval.c (interactive_p, Fsignal, eval_sub, Ffuncall, Fbacktrace)
2389 (Fbacktrace_frame): Adjust accordingly.
2391 2012-09-28 Glenn Morris <rgm@gnu.org>
2393 * eval.c (Frun_hook_with_args, Frun_hook_with_args_until_success)
2394 (Frun_hook_with_args_until_failure): Doc fixes.
2396 2012-09-28 Eli Zaretskii <eliz@gnu.org>
2398 * xdisp.c (syms_of_xdisp) <Qredisplay_internal>: Rename from
2399 Qautomatic_redisplay and change the symbol name. All users changed.
2401 2012-09-28 Tomohiro Matsuyama <tomo@cx4a.org>
2403 * profiler.c (sigprof_handler): Fix race condition.
2405 2012-09-28 Glenn Morris <rgm@gnu.org>

2409 2012-09-27 Paul Eggert <eggert@cs.ucla.edu>
2411 Check more robustly for timer_settime.
2412 * Makefile.in (LIB_TIMER_TIME): New macro.
2414 * atimer.c (alarm_timer, alarm_timer_ok, set_alarm, init_atimer):
2415 Use HAVE_TIMER_SETTIME, not SIGEV_SIGNAL, to decide whether to
2418 2012-09-26 Tomohiro Matsuyama <tomo@cx4a.org>
2420 * profiler.c (Fprofiler_cpu_start): Remove unnecessary flag SA_SIGINFO.
2422 2012-09-26 Juanma Barranquero <lekktu@gmail.com>
2424 * makefile.w32-in ($(BLD)/profiler.$(O)): Update dependencies.
2426 2012-09-26 Paul Eggert <eggert@cs.ucla.edu>
2428 * character.h (MAYBE_UNIFY_CHAR): Remove.
2429 * charset.c, charset.h (maybe_unify_char): Now static.
2430 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
2431 Since this stuff is now private to charset.c, there's no need for
2432 a public macro and no need to inline by hand.
2434 2012-09-26 Tomohiro Matsuyama <tomo@cx4a.org>
2435 Stefan Monnier <monnier@iro.umontreal.ca>
2436 Juanma Barranquero <lekktu@gmail.com>

2446 (total_bytes_of_live_objects): New function.
2447 (Fgarbage_collect): Use it. Record itself in backtrace_list.
2448 Call malloc_probe for the memory profiler.

2460 2012-09-25 Eli Zaretskii <eliz@gnu.org>
2461 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
2463 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
2465 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
2467 Prefer POSIX timers if available.
2468 They avoid a race if the timer is too close to the current time.
2469 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
2470 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
2471 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
2473 2012-09-25 Eli Zaretskii <eliz@gnu.org>
2475 * coding.c (CHAR_STRING_ADVANCE_NO_UNIFY): Make it an alias of
2476 CHAR_STRING_ADVANCE.
2477 (STRING_CHAR_ADVANCE_NO_UNIFY): Make it an alias of
2478 STRING_CHAR_ADVANCE.
2480 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
2482 Move Vlibrary_cache to emacs.c and reset before dumping.
2484 * lisp.h (reset_image_types): Declare.
2485 [WINDOWSNT] (Vlibrary_cache): Declare.
2487 * image.c (reset_image_types): New function.
2489 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.
2490 (syms_of_emacs) [WINDOWSNT] <Vlibrary_cache>: Initialize and staticpro.
2491 (Fdump_emacs): Reset Vlibrary_cache and image_types.
2493 * w32.c (Vlibrary_cache): Do not define; moved to emacs.c
2494 (globals_of_w32) <Vlibrary_cache>: Do not initialize.
2496 * w32.h (Vlibrary_cache): Do not declare.
2498 2012-09-25 Eli Zaretskii <eliz@gnu.org>
2500 * w32proc.c (sys_signal): Handle all signals defined by the
2501 MS-Windows runtime, not just SIGCHLD. Actually install the signal
2502 handlers for signals supported by Windows. Don't override
2503 term_ntproc as the handler for SIGABRT.
2504 (sigaction): Rewrite to call sys_signal instead of duplicating its
2506 (sys_kill): Improve commentary.
2508 * w32.c (term_ntproc): Accept (and ignore) one argument, for
2509 consistency with a signature of a signal handler. All callers
2511 (init_ntproc): Accept an argument DUMPING. If dumping, don't
2512 install term_ntproc as a signal handler for SIGABRT, as that
2513 should be done by the dumped Emacs.
2515 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
2517 * w32select.c (term_w32select): Protect against repeated
2518 invocation by setting clipboard_owner to NULL after calling
2521 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
2522 and term_ntproc to their modified signatures.
2524 * character.c (char_string, string_char): Remove calls to
2525 MAYBE_UNIFY_CHAR. See the discussion starting at
2526 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
2529 2012-09-25 Chong Yidong <cyd@gnu.org>
2531 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
2533 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
2535 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
2536 when encountering an unknown bytecode.
2538 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
2540 image.c, indent.c: Use bool for booleans.
2541 * dispextern.h (struct image_type): Members valid_p, load, init
2542 now return bool, not int. All uses changed.
2543 * image.c: Omit unnecessary static decls.
2544 (x_create_bitmap_mask, x_build_heuristic_mask):
2545 Return void, not int, since callers don't care about the return value.
2546 (x_create_bitmap_mask, define_image_type, valid_image_p)

2574 Use bool for booleans.
2576 2012-09-24 Chong Yidong <cyd@gnu.org>
2578 * chartab.c (Fset_char_table_default): Obsolete function removed.
2580 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
2582 Move pid_t related decls out of lisp.h.
2583 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
2584 (interruptible_wait_for_termination):
2585 Move these decls from lisp.h to syswait.h, since they use pid_t.
2586 Needed on FreeBSD; see Herbert J. Skuhra in
2587 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
2588 * callproc.c: Include syswait.h.
2590 gnutls.c, gtkutil.c: Use bool for boolean.

2605 * nsmenu.m (ns_update_menubar):
2606 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
2607 * xfns.c (Fx_show_tip) [USE_GTK]:
2608 Use bool for boolean.
2609 * gtkutil.c (xg_update_frame_menubar):

2615 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
2617 * makefile.w32-in (BLOCKINPUT_H): Remove.

2634 2012-09-23 Eli Zaretskii <eliz@gnu.org>
2636 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
2637 fatal_error_backtrace.
2639 * w32proc.c (sys_kill): Undo last change: don't do anything when
2640 invoked to deliver SIGABRT to our own process. This is now
2641 handled by emacs_raise.
2643 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
2645 * w32term.c (w32_read_socket): Remove leftover reference to
2646 interrupt_input_pending.
2648 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
2650 Do not use SA_NODEFER.
2651 Problem reported by Dani Moncayo in
2652 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
2654 * sysdep.c (emacs_abort): Do not reset signal handler.
2655 * emacs.c (terminate_due_to_signal): Reset signal handler here.
2656 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
2657 wanted even on POSIXish hosts, and it doesn't work on Windows.
2659 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
2661 * xterm.c (x_term_init): Call fixup_locale before and after calling
2662 gtk_init (Bug#12392).
2664 2012-09-23 Chong Yidong <cyd@gnu.org>
2666 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
2667 Vdynamic_library_alist.
2669 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
2670 (Fgnutls_available_p): Caller changed.
2672 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
2673 (Flibxml_parse_xml_region): Likewise.
2675 * dispextern.h (struct image_type): Remove arg from init function.
2677 * image.c (Finit_image_library, lookup_image_type)
2678 (define_image_type): Remove now-unneeded second arg.
2679 (init_xpm_functions, init_png_functions, init_jpeg_functions)
2680 (init_tiff_functions, init_gif_functions, init_svg_functions):
2681 Arglist and w32_delayed_load calling convention changed.
2682 (gs_type): Remove init_gs_functions; there is no such function.
2683 (valid_image_p, make_image): Fix caller to lookup_image_type.
2685 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
2687 Simplify and avoid signal-handling races (Bug#12471).
2689 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
2690 Avoid recursive loop if there's a fatal error in the function itself.
2691 * atimer.c (pending_atimers):
2692 * blockinput.h: Don't include "atimer.h"; no longer needed.
2693 (interrupt_input_pending): Remove. All uses removed.
2694 pending_signals now counts both atimers and ordinary interrupts.
2695 This is less racy than having three separate pending-signal flags.
2696 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
2698 Rename from their upper-case counterparts BLOCK_INPUT,
2699 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
2700 INPUT_BLOCKED_P, and turn into functions. All uses changed.
2701 This makes it easier to access volatile variables more accurately.
2702 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
2703 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
2704 that's more reliable if the code is buggy and sets
2705 interrupt_input_blocked to a negative value. All uses changed.
2706 * atimer.c (deliver_alarm_signal):
2707 Remove. No need to deliver this to the parent; any thread can
2708 handle this signal now. All uses replaced by underlying handler.
2709 * atimer.c (turn_on_atimers):
2710 * dispnew.c (handle_window_change_signal):
2711 * emacs.c (handle_danger_signal):
2712 * keyboard.c (kbd_buffer_get_event):
2713 Don't reestablish signal handler; not needed with sigaction.
2714 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
2716 Rework to avoid unnecessary accesses to volatile variables.
2717 (UNBLOCK_INPUT_TO): Now a function.
2718 (totally_unblock_input, unblock_input): New decls.
2719 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
2720 (init_data): Remove. Necessary stuff now done in init_signal.
2721 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
2722 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
2723 (fatal_error_code): Remove; no longer needed.
2724 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
2725 it doesn't always backtrace. All uses changed. No need to reset
2726 signal to default, since sigaction and/or die does that for us now.
2727 Use emacs_raise (FOO), not kill (getpid (), FOO).
2728 (main): Check more-accurately whether we're dumping.
2729 Move fatal-error setup to sysdep.c
2730 * floatfns.c: Do not include "syssignal.h"; no longer needed.
2731 * gtkutil.c (xg_get_file_name, xg_get_font):
2732 Remove no-longer-needed signal-mask manipulation.
2733 * keyboard.c, process.c (POLL_FOR_INPUT):
2734 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
2735 * keyboard.c (read_avail_input): Remove.
2736 All uses replaced by gobble_input.
2737 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
2738 (kbd_buffer_store_event_hold, gobble_input):
2739 (record_asynch_buffer_change) [USABLE_SIGIO]:
2740 (store_user_signal_events):
2741 No need to mess with signal mask.
2742 (gobble_input): If blocking input and there are terminals, simply
2743 set pending_signals to 1 and return. All hooks changed to not
2744 worry about whether input is blocked.
2745 (process_pending_signals): Clear pending_signals before processing
2746 them, in case a signal comes in while we're processing.
2747 By convention callers now test pending_signals before calling us.
2748 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
2749 New functions, to support changes to blockinput.h.
2750 (handle_input_available_signal): Now extern.
2751 (reinvoke_input_signal): Remove. All uses replaced by
2753 (quit_count): Now volatile, since a signal handler uses it.
2754 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
2755 All callers changed. Block SIGINT only if not already blocked.
2756 Clear sigmask reliably, even if Fsignal returns, which it can.
2757 Omit unnecessary accesses to volatile var.
2758 (quit_throw_to_read_char): No need to restore sigmask.
2759 * keyboard.c (gobble_input, handle_user_signal):
2760 * process.c (wait_reading_process_output):
2761 Call signal-handling code rather than killing ourselves.
2762 * lisp.h: Include <float.h>, for...
2763 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
2764 (pending_signals): Now volatile.
2765 (syms_of_data): Now const if IEEE floating point.
2766 (handle_input_available_signal) [USABLE_SIGIO]:
2767 (terminate_due_to_signal, record_child_status_change): New decls.
2768 * process.c (create_process): Avoid disaster if memory is exhausted
2769 while we're processing a vfork, by tightening the critical section
2771 (send_process_frame, process_sent_to, handle_pipe_signal)
2772 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
2774 (send_process): No need for setjmp/longjmp any more, since the
2775 SIGPIPE stuff is now gone. Instead, report an error if errno
2777 (record_child_status_change): Now extern. PID and W are now args.
2778 Return void, not bool. All callers changed.
2779 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
2780 Remove. All uses removed. This bug should be fixed now in a
2782 (wait_for_termination_1): Use waitpid rather than sigsuspend,
2783 and record the child status change directly. This avoids the
2784 need to futz with the signal mask.
2785 (process_fatal_action): Move here from emacs.c.
2786 (emacs_sigaction_flags): New function, containing
2787 much of what used to be in emacs_sigaction_init.
2788 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
2789 caught by emacs, to make races less likely.
2790 (deliver_process_signal): Rename from handle_on_main_thread.
2792 (BACKTRACE_LIMIT_MAX): Now at top level.
2793 (thread_backtrace_buffer, threadback_backtrace_pointers):
2795 (deliver_thread_signal, deliver_fatal_thread_signal):
2796 New functions, for more-accurate delivery of thread-specific signals.
2797 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
2798 (deliver_arith_signal): Handle in this thread, not
2799 in the main thread, since it's triggered by this thread.
2800 (maybe_fatal_sig): New function.
2801 (init_signals): New arg DUMPING so that we can be more accurate
2802 about whether we're dumping. Caller changed.
2803 Treat thread-specific signals differently from process-general signals.
2804 Block all signals while handling fatal error; that's safer.
2805 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
2807 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
2808 Ignore SIGPIPE unless batch.
2809 (emacs_backtrace): Output backtrace for the appropriate thread,
2810 which is not necessarily the main thread.
2811 * syssignal.h: Include <stdbool.h>.
2812 (emacs_raise): New macro.
2813 * xterm.c (x_connection_signal): Remove; no longer needed
2814 now that we use sigaction.
2815 (x_connection_closed): No need to mess with sigmask now.
2816 (x_initialize): No need to reset SIGPIPE handler here, since
2817 init_signals does this for us now.
2819 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
2821 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
2822 background rect may be larger (Bug#12245).
2824 2012-09-23 Chong Yidong <cyd@gnu.org>
2826 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
2828 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
2830 * .gdbinit: Just stop at fatal_error_backtrace.
2831 See Stefan Monnier's request in
2832 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
2833 Remove no-longer-used query of system type.
2835 2012-09-22 Chong Yidong <cyd@gnu.org>
2837 * search.c (Freplace_match): Doc fix (Bug#12325).
2839 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
2841 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
2842 (Fline_end_position): Doc fix.
2844 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
2846 2012-09-22 Chong Yidong <cyd@gnu.org>
2848 * dispextern.h (struct image_type): Add new slot, storing a type
2849 initialization function.
2851 * image.c (define_image_type): Call the image initializer function
2852 if it is defined. Arguments and return value changed.
2853 (valid_image_p, make_image): Callers changed.
2854 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
2855 (gif_type, imagemagick_type, svg_type, gs_type):
2856 Add initialization functions.
2857 (Finit_image_library): Call lookup_image_type.
2858 (CHECK_LIB_AVAILABLE): Macro deleted.
2859 (lookup_image_type): Call define_image_type here, rather than via
2860 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
2861 (syms_of_image): Move define_image_type calls for xbm_type and
2862 pbm_type to lookup_image_type.
2864 2012-09-22 Eli Zaretskii <eliz@gnu.org>
2866 * keyboard.c (timer_check_2): Move calculation of 'timers' and
2867 'idle_timers' from here ...
2868 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
2869 lists, to avoid infloops when the timer does something stupid,
2870 like reinvoke itself with the same or smaller time-out.
2873 2012-09-22 Martin Rudalics <rudalics@gmx.at>
2875 * window.c (Fsplit_window_internal): Handle only Qt value of
2876 Vwindow_combination_limit separately.
2877 (Qtemp_buffer_resize): New symbol.
2878 (Vwindow_combination_limit): New default value.
2881 2012-09-22 Eli Zaretskii <eliz@gnu.org>
2883 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
2884 the new overlay string. (Bug#10159)
2886 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
2888 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
2889 or that fprintf is async-signal-safe. POSIX doesn't require
2892 2012-09-22 Chong Yidong <cyd@gnu.org>
2894 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
2897 2012-09-22 Kenichi Handa <handa@gnu.org>
2899 * composite.c (composition_reseat_it): Handle the case that a
2900 grapheme cluster is not covered by a single font (Bug#12352).
2902 2012-09-21 Chong Yidong <cyd@gnu.org>
2904 * image.c (define_image_type): Avoid adding duplicate types to
2905 image_types (Bug#12463). Suggested by Jörg Walter.
2907 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2909 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
2910 (print_load_command_name): Add case LC_DATA_IN_CODE.
2911 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
2913 2012-09-21 Glenn Morris <rgm@gnu.org>
2915 * eval.c (Frun_hook_with_args_until_success)
2916 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
2918 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
2920 * fileio.c (Ffile_selinux_context): Only call freecon when
2921 lgetfilecon succeeded.
2922 (Fset_file_selinux_context): Likewise. (Bug#12444)
2924 2012-09-21 Eli Zaretskii <eliz@gnu.org>
2926 * xdisp.c (try_window_reusing_current_matrix): Under bidi
2927 reordering, locate the cursor by calling set_cursor_from_row; if
2928 that fails, clear the desired glyph matrix before returning a
2929 failure indication to the caller. Fixes leaving garbled display
2930 when fast scrolling with a down-key. (Bug#12403)
2931 (compute_stop_pos_backwards): Fix a typo that caused crashes while
2932 scrolling through multibyte text.
2934 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
2936 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
2937 calling mark_vectorlike since that's the one that marks the window.
2938 (mark_discard_killed_buffers): Mark the final cdr.
2939 * window.h (struct window): Move prev/next_buffers to the
2940 non-standard fields.
2941 * window.c (make_window): Initialize prev/next_buffers manually.
2943 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
2945 Omit unused arg EXPECTED from socket hooks.
2946 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
2947 * nsterm.m (ns_term_init):
2948 * termhooks.h (struct terminal.read_socket_hook):
2949 * w32inevt.c (w32_console_read_socket):
2950 * w32term.c (w32_read_socket):
2951 * xterm.c (XTread_socket):
2952 Omit unused arg EXPECTED. All callers changed.
2953 (store_user_signal_events): Return void, not int, since callers no
2954 longer care about the return value. All uses changed.
2956 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
2958 * w32gui.h (XParseGeometry): Do not declare.
2960 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
2962 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
2963 Ignore 'expected'. See Eli Zaretskii in
2964 <http://bugs.gnu.org/12471#8> (last line).
2966 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
2967 (XParseGeometry): Now static. Substitute extremal values for
2968 values that are out of range.
2970 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
2972 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
2974 * nsfns.m (XParseGeometry): Remove.
2975 (Fx_create_frame): Call x_set_offset to correctly interpret
2976 top_pos in geometry.
2978 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
2979 (Fx_parse_geometry): If there is a space in string, call
2980 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
2982 2012-09-17 Eli Zaretskii <eliz@gnu.org>
2984 * search.c (scan_buffer): Use character positions in calls to
2985 region_cache_forward and region_cache_backward, not byte
2986 positions. (Bug#12196)
2988 * w32term.c (w32_read_socket): Set pending_signals to 1, like
2989 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
2991 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
2992 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
2993 emacs_blocked_malloc, now deleted.
2995 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
2997 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
2998 The workaround was for improving performance on Solaris 2.4, but
2999 is getting in the way now. Emacs will still work if someone is
3000 still running Solaris 2.4 in a museum somewhere; Sun dropped
3001 support for Solaris 2.4 in 2003.
3002 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
3003 * process.c (create_process) [HAVE_WORKING_VFORK]:
3004 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
3005 since Emacs no longer uses vfork on that platform.
3007 2012-09-17 Glenn Morris <rgm@gnu.org>
3009 * emacs.c: Use COPYRIGHT.
3011 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
3013 Remove configure's --without-sync-input option (Bug#12450).
3014 When auditing signal-handling in preparation for cleaning it up,
3015 I found that SYNC_INPUT has race conditions and would be a real
3016 pain to fix. Since it's an undocumented and deprecated
3017 configure-time option, now seems like a good time to remove it.
3018 Also see <http://bugs.gnu.org/11080#16>.
3019 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
3020 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
3021 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3022 (malloc_hysteresis):
3023 (check_depth) [XMALLOC_OVERRUN_CHECK]:
3024 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
3025 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
3026 (dont_register_blocks, bytes_used_when_reconsidered)
3027 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
3028 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
3029 [!SYSTEM_MALLOC && !SYNC_INPUT]:
3030 Remove. All uses removed.
3031 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
3032 implementation, one that depends on whether the new macro
3033 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
3035 * atimer.c (run_timers, handle_alarm_signal):
3036 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
3037 (handle_async_input, process_pending_signals)
3038 (handle_input_available_signal, init_keyboard):
3039 * nsterm.m (ns_read_socket):
3040 * process.c (wait_reading_process_output):
3041 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
3042 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
3044 * xterm.c (XTread_socket):
3046 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
3047 * eval.c (handling_signal): Remove. All uses removed.
3048 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
3049 All uses replaced with the SYNC_INPUT version.
3050 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
3052 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3055 * font.c (Ffont_shape_gstring): Remove unused local.
3057 2012-09-16 Glenn Morris <rgm@gnu.org>
3059 * Makefile.in (clean): No longer run nextstep's clean.
3061 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
3063 (ns-app): Move here from ns.mk, and simplify.
3064 (clean): Simplify nextstep entry.
3065 * ns.mk: Remove file.
3067 2012-09-17 Kenichi Handa <handa@gnu.org>
3069 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
3070 not covert the last few charactes.
3072 2012-09-16 Kenichi Handa <handa@gnu.org>
3074 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
3075 here, but just check the validity of glyphs in the glyph-string.
3077 2012-09-16 Martin Rudalics <rudalics@gmx.at>
3079 * window.c (Fwindow_parameter, Fset_window_parameter):
3080 Accept any window as argument (Bug#12452).
3082 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
3084 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
3085 to ns_term_init to avoid memory leak.
3087 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
3088 explicit retain/release.
3089 (ns_term_init): Only allow one display. Initialize outerpool and
3092 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3094 Port _setjmp fix to POSIXish hosts as well as Microsoft.
3095 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
3096 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
3097 the Microsoft problem in a different way, by altering ../nt/config.nt.
3099 2012-09-15 Eli Zaretskii <eliz@gnu.org>
3114 * w16select.c: Remove inclusion of setjmp.h, as it is now included
3115 by lisp.h. This completes removal of setjmp.h inclusion
3116 erroneously announced in the previous commit. (Bug#12446)
3118 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
3121 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
3122 not defined as a macro. The latter happens on MS-Windows.
3125 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3127 Port better to POSIX hosts lacking _setjmp (Bug#12446).
3128 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
3129 Some instances of '#include <setjmp.h>' removed, if the
3130 only reason for the instance was because "lisp.h" was included.
3131 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
3132 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
3133 and _longjmp with the new symbols. Emacs already uses _setjmp if
3134 available, so this change affects only POSIXish hosts that have
3135 sigsetjmp but not _setjmp, such as some versions of Solaris and
3136 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
3137 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
3138 (png_load_body) [HAVE_PNG]:
3139 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
3140 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
3141 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
3142 since PNG requires jmp_buf. This is the only exception to the
3143 general rule that we now use sys_setjmp and sys_longjmp.
3144 This exception is OK since this code does not change the signal
3145 mask or longjmp out of a signal handler.
3147 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
3149 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3150 Include "syssignal.h", for 'main_thread'.
3152 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
3154 Avoid out-of-range marker position (Bug#12426).
3155 * insdel.c (replace_range, replace_range_2):
3156 Adjust markers before overlays, as suggested by comments.
3157 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
3158 Remove redundant check before calling offset_intervals.
3160 2012-09-14 Martin Rudalics <rudalics@gmx.at>
3162 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
3163 current buffer (Bug#12387).
3165 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
3167 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
3169 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3171 Use a more backwards-compatible timer format (Bug#12430).
3172 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
3173 vector element, not from the 4th, since PSECS is now at the end.
3174 (Fcurrent_idle_time): Doc fix.
3176 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
3178 Function to mark objects and remove killed buffers at once.
3179 * alloc.c (discard_killed_buffers): Rename to ...
3180 (mark_discard_killed buffers) ... new name. Add marking
3181 of remaining objects. Fix comment. Adjust users.
3182 (mark_object): Do not touch frame buffer lists here.
3183 * frame.c (delete_frame): Reset frame buffer lists here.
3185 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3187 Better workaround for GNOME bug when --enable-gcc-warnings.
3188 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
3189 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
3190 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
3192 Simplify SIGIO usage (Bug#12408).
3193 The code that dealt with SIGIO was crufty and confusing, e.g., it
3194 played tricks like "#undef SIGIO" but these tricks were not used
3195 consistently. Simplify mostly by not #undeffing standard symbols,
3196 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
3197 or not as we please) rather than "defined SIGIO" (standard symbol
3198 that we probably shouldn't #undef).
3199 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
3200 Modules that need it can include it.
3201 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
3202 * dispextern.h (ignore_sigio): New decl.
3203 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
3204 unconditionally, since it's now a no-op if !USABLE_SIGIO.
3205 * emacs.c (shut_down_emacs):
3206 * keyboard.c (kbd_buffer_store_event_hold):
3207 Use ignore_sigio rather than invoking 'signal' directly.
3208 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
3210 (FIONREAD, SIGIO): Do not #undef.
3211 (tty_read_avail_input): Use #error rather than a syntax error.
3212 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
3213 for I_PIPE, used by SETUP_SLAVE_PTY.
3214 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
3215 * sysdep.c (croak): Remove; no longer needed. This bit of
3216 temporary code, with Fred N. Fish's comment that it's temporary,
3217 has been in Emacs since at least 1992!
3218 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
3219 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
3220 * syssignal.h (croak): Remove decl.
3221 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
3222 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
3223 now that we're termios-only.
3224 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
3225 * term.c (dissociate_if_controlling_tty): Use #error rather than
3228 Work around GCC and GNOME bugs when --enable-gcc-warnings.
3229 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
3230 to work around GNOME bug 683906.
3231 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
3232 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
3233 This works around GCC bug 54561.
3235 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
3237 More fixes for 'volatile' and setjmp/longjmp.
3238 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
3239 * image.c (struct png_load_context) [HAVE_PNG]: New type.
3240 (png_load_body) [HAVE_PNG]:
3241 (jpeg_load_body) [HAVE_JPEG]:
3242 New function, with most of the old parent function's body.
3243 (png_load) [HAVE_PNG]:
3244 (jpeg_load) [HAVE_JPEG]:
3245 Invoke the new function, to avoid longjmp munging our locals.
3246 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
3247 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
3248 longjmp is passed 2, as the C standard doesn't guarantee this.
3249 Instead, store the failure code into mgr->failure_code.
3251 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
3253 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
3254 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
3255 (syms_of_keyboard): Remove support for unread-command-char.
3257 2012-09-12 Eli Zaretskii <eliz@gnu.org>
3259 * w32proc.c (sys_kill): If PID is our process ID and the signal is
3260 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
3261 violation. (Bug#12426)
3263 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
3265 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
3267 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
3269 * eval.c: Add `inhibit-debugger'.
3270 (Qinhibit_debugger): New symbol.
3271 (call_debugger): Bind it instead of Qdebug_on_error.
3272 (maybe_call_debugger): Test Vinhibit_debugger.
3273 (syms_of_eval): Define inhibit-debugger.
3274 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
3275 (syms_of_xdisp): Remove inhibit-debug-on-message.
3277 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
3279 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
3280 If a nonvolatile local variable is written before a _longjmp to
3281 the frame containing the variable, and is read after the _longjmp,
3282 the value read is indeterminate. Some local variables of type
3283 'struct handler' and 'struct catchtag' are used in this way, so
3284 mark each of their slots as volatile if the slot can be set before
3285 _longjmp and read afterwards.
3286 * lisp.h (struct handler): var and chosen_clause are now volatile.
3287 (struct catchtag): val, next, and pdlcount are now volatile.
3289 * bidi.c (bidi_push_it, bidi_pop_it):
3290 * fns.c (copy_hash_table):
3291 * image.c (define_image_type):
3292 * keyboard.c (kbd_buffer_store_event_hold):
3293 * process.c (Fprocess_send_eof):
3294 * xfaces.c (x_create_gc) [HAVE_NS]:
3295 * xgselect.c (xg_select):
3296 Prefer assignment to memcpy when either will do.
3298 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
3299 Use pointer-to-a-pointer to simplify and avoid a NILP check each
3300 time an item is removed. No need to mark this function 'inline';
3301 the compiler knows better than we do.
3303 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
3305 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
3306 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
3307 to change_frame_size (Bug#12388).
3308 (windowDidResize:): Pass YES to updateFrameSize.
3310 * nsterm.h: Add delay parameter to updateFrameSize.
3312 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
3314 Discard killed buffers from deleted window and frame objects.
3315 This reduces an amount of references to killed buffers and
3316 helps GC to reclaim them faster.
3317 * alloc.c (discard_killed_buffers): New function.
3318 (mark_object): Use it for deleted windows and frames.
3319 (mark_object): If symbol's value is set up for a killed buffer
3320 or deleted frame, restore its global binding.
3321 * data.c (swap_in_global_binding): Add GC notice.
3322 (swap_in_symval_forwarding): Use convenient set_blv_where.
3323 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
3324 * window.h: ... to here.
3326 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
3328 Convenient macro to check whether the buffer is live.
3329 * buffer.h (BUFFER_LIVE_P): New macro.
3330 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
3331 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
3333 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3335 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
3336 composition cases (Bug#12364).
3338 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
3339 overhang of succeeding glyphs overlapping box cursor.
3341 * w32term.c (x_draw_glyph_string): Likewise.
3343 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
3345 Simplify, document, and port floating-point (Bug#12381).
3346 The porting part of this patch fixes bugs on non-IEEE platforms
3347 with frexp, ldexp, logb.
3348 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
3350 * floatfns.c: Simplify discussion of functions that Emacs doesn't
3351 support, by removing commented-out code and briefly listing the
3352 C89 functions excluded. The commented-out stuff was confusing
3353 maintenance, e.g., we thought we needed cbrt but it was commented out.
3354 (logb): Remove decl; no longer needed.
3355 (isfinite): New macro, if not already supplied.
3356 (isnan): Don't replace any existing macro.
3357 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
3358 are present on all C89 platforms.
3359 (Ffrexp): Do not special-case zero, as frexp does the right thing
3361 (Flogb): Do not use logb, as it doesn't have the desired meaning
3362 on hosts that use non-base-2 floating point. Instead, stick with
3363 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
3364 frexp, to avoid getting an unspecified result.
3366 * xdisp.c (Qinhibit_debug_on_message): Now static.
3368 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
3370 * nsterm.m (ns_update_begin): Set clip path to whole view by using
3371 NSBezierPath (Bug#12131).
3373 2012-09-10 Chong Yidong <cyd@gnu.org>
3375 * fns.c (Fdelq, Fdelete): Doc fix.
3377 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
3379 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
3380 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
3382 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
3384 * lisp.h (make_lisp_ptr): New macro to replace XSET.
3385 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
3388 2012-09-09 Eli Zaretskii <eliz@gnu.org>
3390 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
3391 left fringe if the window has a left margin. This avoids leaving
3392 traces of the cursor because its leftmost pixel is not drawn over.
3394 * dispnew.c (update_window_line): When the left margin area of a
3395 screen line is updated, set the redraw_fringe_bitmaps_p flag of
3396 that screen line. (Bug#12277)
3398 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
3400 Assume C89 or later for math functions (Bug#12381).
3401 This simplifies the code, and makes it a bit smaller and faster,
3402 and (most important) makes it easier to clean up signal handling
3403 since we can stop worring about floating-point exceptions in
3404 library code. That was a problem before C89, but the problem
3405 went away many years ago on all practical Emacs targets.
3406 * data.c, image.c, lread.c, print.c:
3407 Don't include <math.h>; no longer needed.
3408 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
3409 might be autoconfigured, as that never happens.
3411 * doprnt.c (DBL_MAX_10_EXP):
3412 * print.c (DBL_DIG):
3413 Remove. C89 or later always defines these.
3414 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
3415 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
3416 (arith_error, domain_error, domain_error2):
3417 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
3418 no longer needed -- we simply return what C returns. All uses removed.
3419 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
3421 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
3422 Remove. All uses expanded, as these macros are no longer used
3423 more than once and are now more trouble than they're worth.
3424 (Ftan): Use tan, not sin / cos.
3425 (Flogb): Assume C89 frexp.
3426 (fmod_float): Assume C89 fmod.
3427 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
3428 (init_floatfns): Remove. All uses removed.
3430 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3432 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
3433 compositeToPoint for OSX < 10.6 (Bug#12390).
3435 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
3437 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
3438 This produces more-accurate results.
3440 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3442 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
3443 changes (Bug#12088).
3445 2012-09-08 Chong Yidong <cyd@gnu.org>
3447 * syntax.c (Fstring_to_syntax): Doc fix.
3449 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3451 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
3452 in the internal border.
3453 (x_set_window_size): Remove static variables and their usage.
3454 (ns_redraw_scroll_bars): Fix NSTRACE arg.
3455 (ns_after_update_window_line, ns_draw_fringe_bitmap):
3456 Remove fringe/internal border adjustment (Bug#11052).
3457 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
3458 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
3459 (ns_fix_rect_ibw): Remove.
3460 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
3461 (ns_dumpglyphs_box_or_relief): Ditto.
3462 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
3464 (ns_dumpglyphs_image): Ditto.
3465 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
3467 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
3468 their usage. Add fringe_extended_p and its use as in other terms.
3469 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
3470 scroll bar was removed.
3471 (updateFrameSize): New function.
3472 (windowDidResize): Move code to updateFrameSize and call it.
3474 * nsterm.h (EmacsView): Add updateFrameSize.
3476 2012-09-07 Chong Yidong <cyd@gnu.org>
3478 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
3480 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
3482 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
3484 More signal-handler cleanup (Bug#12327).
3485 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
3486 Problem introduced when merging patches. Noted by Eli Zaretskii in
3487 <http://bugs.gnu.org/12327#67>.
3488 * floatfns.c: Comment fix.
3489 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
3490 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
3491 and anyway the declaration is harmless even if SIGDANGER is not defined.
3492 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
3493 defined BROKEN_FIONREAD). systty.h formerly did this, but other
3494 source files not surprisingly expected syssignal.h to define, or
3495 not define, SIGIO, and it's cleaner to do it that way, for consistency.
3496 Include <sys/ioctl.h>, for FIONREAD.
3497 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
3498 This eliminates a problem whereby other files mysteriously had
3499 to include "syssignal.h" before including "systty.h" if they
3500 wanted to use "#ifdef SIGIO".
3502 2012-09-07 Eli Zaretskii <eliz@gnu.org>
3504 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
3506 * w32.c (sigemptyset): Empty the set.
3507 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
3509 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
3511 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
3513 * alloc.c (mark_buffer): Revert unsafe marking optimization.
3514 (mark_object): Likewise for frame objects.
3516 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
3518 * syssignal.h (handle_on_main_thread): Always declare,
3519 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
3520 This ports to platforms without HAVE_PTHREAD.
3522 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
3524 Signal-handler cleanup (Bug#12327).
3525 Emacs's signal handlers were written in the old 4.2BSD style with
3526 sigblock and sigmask and so forth, and this led to some
3527 inefficiencies and confusion. Rewrite these to use
3528 pthread_sigmask etc. without copying signal sets around. Also,
3529 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
3530 'signal', and instead use functions that do not attempt to take
3531 over the system name space. This patch causes Emacs's text
3532 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
3533 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
3534 Do not include <signal.h> or "syssignal.h", as these
3535 modules do not use signals.
3536 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
3537 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
3538 Do not include <signal.h>, as "syssignal.h" does that for us now.
3539 * atimer.c (sigmask_atimers): New function.
3540 (block_atimers, unblock_atimers): New functions,
3541 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
3543 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
3544 no longer needed here.
3545 * emacs.c (main): Inspect existing signal handler with sigaction,
3546 so that there's no need to block and unblock SIGHUP.
3547 * sysdep.c (struct save_signal): New member 'action', replacing
3548 old member 'handler'.
3549 (save_signal_handlers, restore_signal_handlers):
3550 Use sigaction instead of 'signal' to save and restore.
3551 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
3552 New function. All users of 'signal' modified to use set_sighandler
3553 if they're writeonly, and to use sys_signal if they're read+write.
3554 (emacs_sigaction_init, forwarded_signal): New functions.
3555 (sys_signal): Remove. All uses replaced by calls to sigaction
3556 and emacs_sigaction_init, or by direct calls to 'signal'.
3557 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
3558 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
3559 all uses replaced by pthread_sigmask etc. calls.
3560 * syssignal.h: Include <signal.h>.
3561 (emacs_sigaction_init, forwarded_signal): New decls.
3562 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
3563 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
3564 (sigmask, sys_sigmask): Remove; no longer needed.
3565 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
3566 (sigblock, sigunblock, sigfree):
3567 (sigsetmask) [!defined sigsetmask]:
3568 Remove. All uses replaced by pthread_sigmask.
3569 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
3570 no longer need to be replaced, and its typical old uses
3571 are now done via emacs_sigaction_init and sigaction.
3572 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
3573 (sys_sigdel): Remove; unused.
3574 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
3576 2012-09-06 Eli Zaretskii <eliz@gnu.org>
3578 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
3579 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
3581 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
3583 Explicitly mark buffer_defaults and buffer_local_symbols.
3584 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
3585 mark_local_symbols here.
3586 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
3587 since special buffers aren't marked here any more.
3588 (allocate_buffer): Chain new buffer with all_buffers here...
3589 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
3591 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
3592 (syms_of_buffer): Remove staticpro of the above.
3593 (init_buffer_once): Set names for buffer_defaults and
3594 buffer_local_symbols.
3596 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
3598 Use bool for booleans in font-related modules.
3599 * font.c (font_intern_prop, font_style_to_value)
3600 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
3601 (generate_otf_features, font_check_otf_features, font_check_otf)
3602 (font_match_p, font_list_entities, font_at):
3603 * fontset.c (fontset_id_valid_p, reorder_font_vector
3604 (fontset_find_font, Fset_fontset_font)
3605 (face_suitable_for_char_p) [0]:
3606 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
3607 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
3608 (m17n_flt_initialized, ftfont_shape_by_flt):
3609 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
3610 * nsfont.m (nsfont_draw):
3611 * w32font.c (w32font_draw):
3612 * w32term.c (x_draw_glyphless_glyph_string_foreground):
3613 Use bool for booleans.
3614 * font.h: Adjust to above API changes.
3615 (struct font, struct font_driver, struct font_driver_list):
3616 Use bool for booleans.
3617 (struct font): Remove useless member encoding_type.
3619 * fontset.c, xftfont.c: Omit unnecessary static decls.
3621 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
3623 * alloc.c (mark_object): Revert window marking code
3624 since it's unsafe for the Fset_window_configuration.
3626 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
3628 Fix race conditions with signal handlers and errno (Bug#12327).
3629 Be more systematic about preserving errno whenever a signal
3630 handler returns, even if it's not in the main thread. Do this by
3631 renaming signal handlers to distinguish between signal delivery
3632 and signal handling. All uses changed.
3633 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
3634 * data.c (deliver_arith_signal): Rename from arith_error.
3635 * dispnew.c (deliver_window_change_signal): Rename from
3636 window_change_signal.
3637 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
3638 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
3639 * keyboard.c (deliver_input_available_signal): Rename from
3640 input_available_signal.
3641 (deliver_user_signal): Rename from handle_user_signal.
3642 (deliver_interrupt_signal): Rename from interrupt_signal.
3643 * process.c (deliver_pipe_signal): Rename from send_process_trap.
3644 (deliver_child_signal): Rename from sigchld_handler.
3645 * atimer.c (handle_alarm_signal):
3646 * data.c (handle_arith_signal):
3647 * dispnew.c (handle_window_change_signal):
3648 * emacs.c (handle_fatal_signal, handle_danger_signal):
3649 * keyboard.c (handle_input_available_signal):
3650 * keyboard.c (handle_user_signal, handle_interrupt_signal):
3651 * process.c (handle_pipe_signal, handle_child_signal):
3652 New functions, with the actual signal-handling code taken from the
3653 original respective signal handlers, sans the sporadic attempts to
3654 preserve errno, since that's now done by handle_on_main_thread.
3655 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
3656 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
3657 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3659 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3660 Move initialization of main_thread to sysdep.c's init_signals.
3661 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
3662 our usage, and simplifies the mainline code.
3663 (record_child_status_change): New static function, as a helper
3664 for handle_child_signal, and with most of the old child handler's
3666 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
3667 (handle_child_signal): Use the above.
3668 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3669 Moved here from emacs.c.
3670 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
3671 code moved here from emacs.c's main function.
3672 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
3673 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
3674 This lets callers save and restore errno properly.
3676 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3678 Remove redundant or unused things here and there.
3679 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
3680 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
3681 * editfns.c (Fcompare_buffer_substrings): Likewise.
3682 * frame.h (struct terminal, struct font_driver_list):
3683 Remove redundant declarations.
3684 * window.h (Qleft, Qright): Likewise.
3686 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3688 Do not mark objects from deleted buffers, windows and frames.
3689 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
3690 (mark_object): Likewise for windows and frames.
3692 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3694 * alloc.c (valid_lisp_object_p): Treat killed buffers,
3695 buffer_defaults and buffer_local_symbols as valid objects.
3696 Return special value to denote them.
3698 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
3700 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
3701 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
3702 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
3703 (file_name_absolute_p, Fsubstitute_in_file_name):
3704 (check_executable, check_writable, Ffile_accessible_directory_p)
3705 (Fset_file_selinux_context, Fdefault_file_modes)
3706 (Finsert_file_contents, choose_write_coding_system)
3707 (Fwrite_region, build_annotations, a_write, e_write)
3709 * filelock.c (boot_time_initialized, get_boot_time)
3710 (get_boot_time_1, lock_file_1, within_one_second):
3711 * floatfns.c (in_float):
3712 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
3713 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
3714 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
3715 * lisp.h (struct Lisp_Hash_Table.cmpfn):
3716 * window.c (compare_window_configurations):
3717 Use bool for booleans.
3718 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
3719 (Fdefault_file_modes): Now mode_t, not int, for modes.
3720 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
3721 (internal_delete_file): Now returns void, not a (boolean) int,
3722 since nobody was looking at the return value.
3723 * lisp.h, window.h: Adjust to above API changes.
3725 * xdisp.c (set_message): Simplify and reindent last change.
3727 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
3729 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
3731 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
3733 * eval.c (call_debugger): Make the function non-static so that we
3734 can call it from set_message.
3736 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
3737 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
3739 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3741 Give more-useful info on a fatal error (Bug#12328).
3742 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
3743 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
3744 of doing the work ourselves.
3745 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
3746 do most of the work.
3747 (fatal_error_backtrace): New function, taken from the guts
3748 of the old fatal_error_signal, but with a new option to output
3750 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
3751 info about the signal than just its number.
3752 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
3753 * sysdep.c: Include <execinfo.h>
3754 (emacs_backtrace): New function, taken partly from the previous
3755 code of the 'die' function.
3756 (emacs_abort): Call fatal_error_backtrace rather than abort.
3758 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
3760 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
3761 eager (load-time) macro-expansion.
3762 * lisp.mk (lisp): Add macroexp.
3764 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3766 Simplify redefinition of 'abort' (Bug#12316).
3767 Do not try to redefine the 'abort' function. Instead, redo
3768 the code so that it calls 'emacs_abort' rather than 'abort'.
3769 This removes the need for the NO_ABORT configure-time macro
3770 and makes it easier to change the abort code to do a backtrace.
3771 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
3772 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
3773 Remove; sysdep.c's emacs_abort now takes its place.
3774 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
3775 'abort' changed to use 'emacs_abort'.
3776 * msdos.c (dos_abort) [defined abort]: Remove; not used.
3777 (abort) [!defined abort]: Rename to ...
3778 (emacs_abort): ... new name.
3779 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
3780 the place of the old 'abort' in emacs.c.
3781 * w32.c, w32fns.c (abort): Do not #undef.
3782 * w32.c (emacs_abort): Rename from w32_abort.
3784 2012-09-04 Eli Zaretskii <eliz@gnu.org>
3786 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
3787 offsets[j].dv, since the y axis of the screen coordinates points
3788 down, while the y axis of the font definition coordinates points
3789 up. This fixes display of Arabic diacritics such as KASRA and
3790 KASRATAN. (Bug#11860)
3792 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3794 Be more systematic about _setjmp vs setjmp.
3795 * alloc.c (test_setjmp, mark_stack):
3796 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
3797 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
3798 (png_load, my_error_exit, jpeg_load):
3799 * process.c (send_process_trap, send_process):
3800 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
3801 The underscored versions are up to 30x faster on some hosts.
3802 Formerly, the code used setjmp+longjmp sometimes and
3803 _setjmp+_longjmp at other times, with no particular reason to
3804 prefer setjmp+longjmp.
3806 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
3808 Fix minor problem found by static checking.
3809 * buffer.c (Fdelete_all_overlays): Return nil.
3811 2012-09-03 Martin Rudalics <rudalics@gmx.at>
3813 * buffer.c (Fdelete_all_overlays): New function.
3815 2012-09-03 Chong Yidong <cyd@gnu.org>
3817 * gtkutil.c: Add extern decl for Qxft.
3819 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

3833 All callers changed.
3834 * eval.c (interactive_p): Omit always-true boolean argument
3835 EXCLUDE_SUBRS_P. All callers changed.
3836 * dispextern.h, lisp.h: Reflect above API changes.
3837 * firstfile.c (dummy): Use the address of 'main', whose signature
3838 won't change, instead of the address of 'initialize', whose
3839 signature just changed from int to bool.
3840 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
3841 * msdos.c (fatal_error_in_progress): ... from here.
3842 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
3844 (redisplay_internal, unwind_redisplay): Simply clear
3845 REDISPLAYING_P when unwinding, instead of saving its previous,
3846 always-false value and then restoring it.
3848 Clean up some extern decls.
3849 Mostly, this hoists extern decls out of .c files and into .h files.
3850 That way, we're more likely to catch errors if the interfaces change.
3851 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
3852 declare xg_mark_data.
3853 * dispextern.h (x_frame_parm_handlers):
3855 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
3856 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)

3869 * widget.c (free_frame_faces):
3870 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
3871 * xfont.c (x_clear_errors):
3872 * xterm.c (x_frame_parm_handlers):
3873 Remove now-redundant extern decls.
3874 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
3875 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
3877 * xfaces.c: Remove unnecessary static decls.
3878 * xterm.c (updating_frame): Remove decl of nonexistent object.
3880 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
3881 when building globals.h, as the objects that are not built on
3882 this host are not needed to compile C files on this host.
3884 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
3886 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

3899 (format_time_string, general_insert_function)
3900 (make_buffer_string, make_buffer_string_both)
3901 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):
3902 * insdel.c (check_markers, gap_left, adjust_markers_for_insert)
3903 (copy_text, insert_1, insert_1_both, insert_from_string)

3912 (get_property_and_range, compare_string_intervals)
3913 (set_intervals_multibyte_1, set_intervals_multibyte):
3914 * keyboard.c (decode_timer):
3915 Use bool for boolean.
3916 * intervals.h, lisp.h, systime.h: Reflect above API changes.
3917 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
3919 2012-09-02 Chong Yidong <cyd@gnu.org>
3921 * keymap.c (push_key_description): Print M-TAB as C-M-i
3924 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
3926 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
3927 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

3932 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
3934 2012-09-01 Eli Zaretskii <eliz@gnu.org>
3936 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
3937 more than one grapheme cluster passed to the shaper: compute the
3938 offset adjustment values separately for each cluster. (Bug#11860)
3940 * image.c: Restore mistakenly removed inclusion of w32.h. Without
3941 it, GCC doesn't see prototypes of w32_delayed_load, and complains
3942 about implicit conversions from integer to pointer.
3944 2012-09-01 Daniel Colascione <dancol@dancol.org>
3946 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
3947 system used too early.
3949 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
3951 Better seed support for (random).

3980 * process.c: Include TERM_HEADER instead of listing all possible
3981 window-system headers.
3983 * nsterm.h: Remove declarations now in frame.h.
3984 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
3986 * menu.c: Include TERM_HEADER instead of listing all possible
3987 window-system headers.
3989 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
3992 * keyboard.c: Include TERM_HEADER instead of listing all possible
3993 window-system headers.
3995 * image.c: Include TERM_HEADER instead of listing all possible
3996 window-system headers. Declare Vlibrary_cache when compiling for
3999 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
4000 window system declarations.
4002 * frame.h: Move common functions here: set_frame_menubar,
4003 x_set_window_size, x_sync, x_get_focus_frame,
4004 x_set_mouse_position, x_set_mouse_pixel_position,
4005 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,
4006 x_char_width, x_char_height, x_pixel_width, x_pixel_height,
4007 x_set_frame_alpha, x_set_menu_bar_lines, x_set_tool_bar_lines,

4026 the current window system; include in list of objects to link into
4029 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
4031 Remove mark_ttys function and fix tty_display_info initialization.
4032 * lisp.h (mark_ttys): Remove prototype.
4033 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
4034 to mark_ttys because all possible values of 'top_frame' slot are
4035 the frames which are reachable from Vframe_list.
4036 * term.c (mark_ttys): Remove.
4037 (init_tty): Safely initialize 'top_frame' slot with Qnil.
4039 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
4041 Change struct frame bitfields from unsigned char to unsigned.
4042 * frame.h (struct frame): Change type of 'display_preempted',

4044 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
4045 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
4046 bitfields from unsigned char to unsigned.
4048 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
4050 Remove unused member of struct x_output and struct w32_output.

4054 2012-08-30 Jan Djärv <jan.h.d@swipnet.se>
4056 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
4057 does not become zero (Bug#12234).
4059 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
4061 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
4062 for GCC 4.7.1 x86-64.
4064 2012-08-30 Glenn Morris <rgm@gnu.org>
4066 * lread.c (init_lread): For out-of-tree builds, only add the
4067 source directory's site-lisp dir to the load-path if it exists,
4068 consistent with in-tree builds. (Bug#12302)
4070 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
4072 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize
4073 button_values to NULL. Call setStykeMask so dialogs get a close button.
4074 (windowShouldClose:): Set window_closed.
4075 (dealloc): New member, free button_values.
4076 (process_dialog:): Make member function. Remove window argument,
4077 replace window with self. Count buttons and allocate and store values
4079 (addButton:value:row:): value is int with the name tag. Call setTag
4080 with tag. Remove return self, declare return value as void.
4081 (addString:row:): Remove return self, declare return value as void.
4082 (addSplit): Remove return self, declare return value as void.
4083 (clicked:): Remove return self, declare return value as void.
4084 Set dialog_return to button_values[seltag]. Code formatting change.
4085 (initFromContents:isQuestion:): Adjust call to process_dialog.
4086 Code formatting change.
4087 (timeout_handler:): Set timer_fired to YES.
4088 (runDialogAt:): Set timer_fired to NO.
4089 Handle click on close button as quit.
4091 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
4092 Add window_closed and button_values. Add void as return value for
4093 add(Button|String|Split). addButton takes int instead of Lisp_Object.
4094 Add process_dialog as new member.
4096 2012-08-28 Eli Zaretskii <eliz@gnu.org>
4098 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
4099 is not one of the heaps we manage. (Bug#12242)
4101 2012-08-28 Glenn Morris <rgm@gnu.org>
4103 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)

4114 * buffer.c (Fset_buffer_major_mode): Signal an error
4115 if the buffer is dead.
4116 (Fother_buffer, other_buffer_safely): Remove redundant
4119 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
4121 Always use set_buffer_if_live to restore original buffer at unwind.
4122 * buffer.h (record_unwind_current_buffer): New function.
4123 * bytecode.c, dispnew.c, editfns.c, fileio.c, fns.c, insdel.c:
4124 * keyboard.c, keymap.c, minibuf.c, print.c, process.c, textprop.c:
4125 * undo.c, window.c: Adjust users.
4126 * buffer.c (set_buffer_if_live): Fix comment.
4128 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
4130 Fix usage of set_buffer_internal.
4131 * buffer.h (set_buffer_internal): Make it BUFFER_INLINE.
4132 * buffer.c (set_buffer_if_live): Use set_buffer_internal.
4133 * coding.c (decode_coding): Omit redundant test.

4137 * keyboard.c (command_loop_1): Likewise.
4138 * print.c (PRINTFINISH): Likewise.
4139 * xdisp.c (run_window_scroll_functions): Use set_buffer_internal.
4141 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>

4160 Use bool for boolean.
4161 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
4162 and remove last int (actually boolean) argument, which was always 0.
4163 All callers changed.
4164 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
4165 * dispextern.h (struct composition_it): Use bool for boolean.
4166 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
4167 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
4168 * dired.c (file_name_completion):
4169 Use bool for boolean. (This was missed in an earlier change.)
4171 2012-08-27 Martin Rudalics <rudalics@gmx.at>
4173 * window.c (Fset_window_configuration): Revert first part of
4176 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
4178 * nsterm.h (NSPanel): New class variable dialog_return.
4180 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
4181 Initialize dialog_return.
4182 (windowShouldClose:): Use stop instead of stopModalWithCode.
4183 (clicked:): Ditto, and also set dialog_return (Bug#12258).
4184 (timeout_handler:): Use stop instead of abortModal. Send a dummy
4186 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when

4201 Use bool for booleans.
4202 * dired.c (file_name_completion):

4230 * fileio.c (Finsert_file_contents):
4231 Use bool for booleans.
4232 * coding.h, lisp.h: Reflect above API changes.
4233 * coding.c: Remove unnecessary static function decls.
4234 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
4235 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
4236 not a boolean 'int', since callers never look at the return value.
4237 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
4238 * coding.h (decoding_buffer_size, encoding_buffer_size)
4239 (emacs_mule_string_char): Remove unused extern decls.
4240 (struct iso_2022_spec, struct coding_system):
4241 Use 'unsigned int : 1' for boolean fields, since there's more than one.
4242 (struct emacs_mule_spec): Remove unused field 'full_support'.
4243 All initializations removed.
4244 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
4246 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
4248 Fix spare memory change (Bug#12286).
4249 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
4250 (valid_lisp_object_p): Likewise.
4252 2012-08-27 Martin Rudalics <rudalics@gmx.at>
4254 * window.c (Fset_window_configuration): Record any window's old
4255 buffer if it's replaced (see Bug#8789). If the new current
4256 buffer doesn't appear in the selected window, go to its old
4259 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
4261 Special MEM_TYPE_SPARE to denote reserved memory.
4262 * alloc.c (enum mem_type): New memory type.
4263 (refill_memory_reserve): Use new type for spare memory.
4264 This prevents live_cons_p and live_string_p from incorrect
4265 detection of uninitialized objects from spare memory as live.
4267 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
4270 * Makefile.in (.PHONY): versioclean -> versionclean.
4272 Remove unused external symbols.
4273 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
4274 * window.c (Qwindow_valid_p, decode_valid_window):
4275 Now static, not extern.
4276 * data.c (Qinterval): Remove; unused.
4277 (syms_of_data): Do not define 'interval'.
4278 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
4279 * window.h (decode_valid_window):
4282 * character.c, charset.c, chartab.c: Use bool for booleans.

4292 (char_table_set_range, optimize_sub_char_table)
4293 (map_sub_char_table):
4294 Use bool for boolean.
4295 * character.c (str_to_unibyte): Omit last boolean argument; it was
4296 always 0. All callers changed.
4297 * character.h, charset.h: Adjust to match previous changes.
4298 * character.h (char_printable_p): Remove decl of nonexistent function.
4299 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
4300 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
4301 are all boolean, so make them single-bit bitfields.
4303 * lisp.h (ASET): Remove attempt to detect side effects.
4304 It was meant to be temporary and it often doesn't work,
4305 because when IDX has side effects the behavior of IDX==IDX
4306 is undefined. See Stefan Monnier in
4307 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
4309 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
4311 * lisp.h (functionp): New function (extracted from Ffunctionp).
4312 (FUNCTIONP): Use it.
4313 * eval.c (Ffunctionp): Use it.
4315 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
4317 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
4318 as that's faster and simpler than static storage. Don't bother
4319 with the g_main_context_query overhead if g_main_context_pending
4320 says no events are pending.
4321 (gfds, gfds_size): Remove these static vars.
4322 (xgselect_initialize): Remove; no longer needed.
4323 All uses and decls removed.
4325 * emacs.c (fatal_error_signal_hook): Remove.
4326 All uses removed. This leftover from old code was always 0.
4328 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
4329 * casefiddle.c (casify_object, casify_region):
4330 * casetab.c (set_case_table):
4331 * category.c, category.h (word_boundary_p):
4332 * category.h (CHAR_HAS_CATEGORY):
4333 Use bool for booleans, instead of int.
4335 2012-08-25 Eli Zaretskii <eliz@gnu.org>
4337 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
4339 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
4341 On assertion failure, print backtrace if available.
4342 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
4343 (die) [ENABLE_CHECKING]: Print a backtrace if available.
4344 * Makefile.in (LIB_EXECINFO): New macro.
4347 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
4348 * bytecode.c (exec_byte_code):
4349 * callint.c (check_mark, Fcall_interactively):
4350 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
4351 (getenv_internal, sync_process_alive, call_process_exited):
4352 * lisp.h (USE_SAFE_ALLOCA):
4353 Use bool for booleans, instead of int.
4354 * lisp.h, process.h: Adjust prototypes to match above changes.
4355 * callint.c (Fcall_interactively): Don't assume the mark's
4356 offset fits in 'int'.
4358 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
4360 * buffer.c, buffer.h: Use bool for boolean.
4361 * buffer.c (reset_buffer_local_variables)

4367 (mmap_enlarge, mmap_set_vars):
4368 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
4369 Use bool for booleans, instead of int.
4370 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
4371 since the 1-or-0 return value is always ignored anyway.
4372 (mmap_initialized_p):
4373 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
4374 * buffer.h, lisp.h: Adjust prototypes to match above changes.
4376 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
4378 * bidi.c: Use bool for boolean.
4379 This is a bit more readable, and makes the text segment of bidi.o
4380 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
4381 Presumably it's faster too.
4382 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
4384 (bidi_cache_find_level_change, bidi_cache_iterator_state)
4385 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
4386 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
4387 (bidi_explicit_dir_char, bidi_level_of_next_char)
4388 (bidi_find_other_level_edge, bidi_move_to_visually_next):
4389 Use bool for booleans, instead of int.
4390 * dispextern.h (bidi_init_it, bidi_paragraph_init)
4391 (bidi_unshelve_cache): Adjust decls to match code.
4393 2012-08-23 Martin Rudalics <rudalics@gmx.at>
4395 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
4398 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
4400 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
4401 * atimer.h: Include <stdbool.h>.
4403 2012-08-22 Dan Nicolaescu <dann@gnu.org>
4405 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
4406 compile time tests instead of run time tests on systems that do
4408 (FRAME_MAC_P): Remove leftover from deleted code.
4409 * frame.c (syms_of_frame): Remove leftover from deleted code.
4411 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
4413 * nsterm.m (insertText:): Don't clear modifiers if code is space.
4415 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
4417 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
4418 Otherwise, the compiler complains about (A?B:C) where B is void
4419 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
4420 (fontset_add): Return void, for FONTSET_ADD.
4422 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4424 * alloc.c: Use bool for booleans.
4425 (gc_in_progress, abort_on_gc)
4426 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
4427 (dont_register_blocks) [GC_MALLOC_CHECK]:
4428 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
4429 (check_string_bytes, make_specified_string, memory_full)
4430 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
4431 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
4432 (mark_stack, valid_pointer_p, make_pure_string)
4433 (Fgarbage_collect, survives_gc_p, gc_sweep):
4434 Use bool for booleans, instead of int.
4435 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
4436 Remove unused local.
4437 * alloc.c (PURE_POINTER_P):
4438 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
4439 * editfns.c (Fformat):
4440 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
4442 * fns.c (sweep_weak_table):
4443 * lisp.h (suppress_checking, push_message, survives_gc_p)
4444 (make_pure_string, gc_in_progress, abort_on_gc):
4445 * lread.c (readchar, read1):
4446 * print.c (Fprin1_to_string):
4447 * xdisp.c (push_message):
4448 Use bool for booleans affected directly or indirectly by
4451 Make recently-introduced setters macros.
4452 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
4453 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
4454 (set_fontset_default, set_fontset_fallback): Rename from their
4455 upper-case counterparts, and make them functions rather than macros.
4456 This is more consistent with the other recently-introduced setters.
4457 These don't need to be inline, since they're local.
4459 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
4461 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
4462 the loop (Bug#12247).
4464 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4466 * lisp.h (vcopy): Use memcpy rather than our own loop.
4467 This fixes a performance regression introduced by the recent
4468 addition of vcopy. This means 'vcopy' will need to be modified
4469 for a copying collector, but that's OK. Also, tighten the
4470 checking in the assertion.
4472 2012-08-21 Eli Zaretskii <eliz@gnu.org>
4474 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
4475 components for RTL text (Bug#11860). Adjust X-OFFSET of each
4476 non-base glyph for the width of the base character, according to
4477 what x_draw_composite_glyph_string_foreground expects.
4478 Generate WADJUST value according to composition_gstring_width's
4479 expectations, to produce correct width of the composed character.
4480 Reverse the sign of the DU offset produced by ScriptPlace.
4482 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4484 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
4486 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
4488 Avoid direct writes to contents member of struct Lisp_Vector.
4489 * lisp.h (vcopy): New function to copy data into vector.
4490 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
4491 * fns.c (Ffillarray): Use ASET.
4492 * keyboard.c (timer_check_2): Use AREF and ASET.
4493 (append_tool_bar_item, Frecent_keys): Use vcopy.
4494 * lread.c (read_vector): Use ASET.
4495 * msdos.c (Frecent_doskeys): Use vcopy.
4496 * xface.c (Finternal_copy_lisp_face): Use vcopy.
4497 (Finternal_merge_in_global_face): Use ASET and vcopy.
4498 * xfont.c (xfont_list_pattern): Likewise.
4500 2012-08-21 Martin Rudalics <rudalics@gmx.at>
4502 * window.c (Fwindow_point): For the selected window always return
4503 the position of its buffer's point.
4504 (Fset_window_point): For the selected window always go in its
4505 buffer to the specified position.
4507 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
4509 Setter macros for fontsets.
4510 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
4511 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
4512 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
4515 2012-08-20 Glenn Morris <rgm@gnu.org>
4517 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
4518 Don't assume that `ln -f' works.
4520 2012-08-20 Eli Zaretskii <eliz@gnu.org>
4522 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
4523 and later about non-assignments with no effect. See discussion at
4524 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
4527 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
4529 Inline setter functions for Lisp_Objects slots of struct specbinding.
4530 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.

4548 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
4549 (set_hash_hash, set_hash_index): Rename with _slot suffix.

4566 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
4568 Rely on <config.h> + <unistd.h> to declare 'environ',
4569 as gnulib does this if the system doesn't.
4570 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
4571 Remove declaration. MS-Windows declares it on stdlib.h which is

4606 Return void, not Lisp_Object. Otherwise, the compiler
4607 complains about (A?B:C) where B is void and C is Lisp_Object

5439 2012-08-04 Eli Zaretskii <eliz@gnu.org>
5441 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
5442 * w32.c (init_environment): Change the default values of many
5443 environment variables in dflt_envvars[] to NULL, to avoid pushing
5444 them into environment when they were not already defined.
5445 Remove the code that deletes site-lisp subdirectories from the default
5446 value of EMACSLOADPATH, as it is no longer needed.
5447 (check_windows_init_file): Now external, not static.
5448 Use Vload_path as is, without adding anything, as this function is now
5449 called when Vload_path is already set up.
5451 * w32.h (check_windows_init_file): Add prototype.
5453 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
5454 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
5455 compatibility with Posix platforms.
5456 (main): Move the call to check_windows_init_file to here from
5458 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
5459 any, in the DEFALT argument into the root of the Emacs build or
5460 installation tree, as appropriate.
5462 * callproc.c (init_callproc_1): Call decode_env_path instead of
5463 doing its equivalent by hand.
5464 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
5465 the code that sets Vexec_path run on MS-Windows.
5467 * lread.c (init_lread): Add comments to #ifdef's.
5469 * msdos.c (dos_set_window_size, IT_update_begin)
5470 (IT_frame_up_to_date, IT_set_frame_parameters): Use FVAR and WVAR
5471 instead of direct references.

5475 Export DEFAULT_REHASH_* to GDB.
5476 * lisp.h (DEFAULT_REHASH_THRESHOLD, DEFAULT_REHASH_SIZE):
5477 Now constants, not macros.
5479 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
5481 Remove unnecessary casts involving pointers.
5482 These casts are no longer needed now that we assume C89 or later,
5483 since they involve casting to or from void *.
5484 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
5485 (make_pure_float, make_pure_vector):
5486 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

5495 (x_get_window_property, x_get_window_property_as_lisp_data):
5496 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
5497 Remove unnecessary pointer casts.
5498 * alloc.c (record_xmalloc): New function.
5499 * lisp.h (record_xmalloc): New decl.
5500 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
5501 more like a function. This is because the pointer cast is not
5502 needed. All uses changed.
5503 * print.c (print_string, print_error_message): Avoid length recalc.
5505 Improve fix for macroexp crash with debugging (Bug#12118).
5506 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
5507 ARRAY_MARK_FLAG when checking subscripts, because ASET is
5508 not supposed to be invoked from the garbage collector.
5509 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
5510 (gc_aset): New function, which is like ASET but can be
5511 used in the garbage collector.
5512 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

5524 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
5525 (map_w32_filename): Improve commentary. Simplify switch.
5526 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
5527 headers (most versions of MinGW w32api don't).
5528 (get_security_info, create_symbolic_link)
5529 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
5531 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
5532 in the argument file name.

5535 (sys_rename): Diagnose renaming of a symlink when the user doesn't
5536 have the required privileges.
5537 (get_file_security_desc_by_name): Rename from
5538 get_file_security_desc.
5539 (stat_worker): New function, with most of the guts of 'stat', and
5540 with addition of handling of symlinks and support for 'lstat'.
5541 If possible, get file's attributes and security information by
5542 handle, not by name. Produce S_IFLNK bit for symlinks, when
5543 called from 'lstat'.
5544 (stat, lstat): New functions, call 'stat_worker'.
5545 (symlink, readlink, careadlinkat): Rewritten to create and resolve
5546 symlinks when the underlying filesystem supports them.
5548 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
5550 Fix macroexp crash on Windows with debugging (Bug#12118).
5551 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
5552 checking subscripts; problem introduced with the recent
5553 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
5554 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
5555 since it's used in non-static inline functions now.
5557 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
5558 Don't assume buffer size fits in 'int'. Remove unused local.

5576 * character.c (CHARACTER_INLINE):
5577 * charset.c (CHARSET_INLINE):
5578 * composite.c (COMPOSITE_INLINE):
5579 * dispnew.c (DISPEXTERN_INLINE):
5580 * sysdep.c (SYSTIME_INLINE):
5581 Define to EXTERN_INLINE, so that the corresponding functions
5582 are compiled into code.
5583 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
5584 (INLINE_HEADER_END): New macros.
5585 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

5605 hard-coding the path separator.
5607 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
5609 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
5610 This how ASET and AREF are supposed to work, and makes
5611 it easier to think about future improvements. See
5612 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
5613 * charset.h (set_charset_attr): New function.

5867 does that unconditionally. Remove file, which is now empty.
5869 * s/freebsd.h, s/gnu-linux.h, s/sol2-6.h, s/unixware.h:
5872 2012-07-30 Paul Eggert <eggert@cs.ucla.edu>

5990 * w32inevt.c: Include w32inevt.h.
5991 (w32_read_console_input): New inline function, calls either

5993 w32_console_unicode_input.
5994 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
5995 (w32_kbd_patch_key, key_event): Use the codepage returned by
5996 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.

6028 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
6029 enumeration constants, as PURE and HEAP are too general, and clash
6030 with other headers and sources, such as gmalloc.c and the
6031 MS-Windows system headers. All users changed.
6033 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
6035 Revert last save_excursion_save and save_excursion_restore changes.
6036 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

6049 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
6050 arms of an 'if', not using conditional expressions; otherwise GDB
6051 complains about the types in the unevaluated arm when the argument
6052 is an integer literal.
6053 (xgetint): Simplify expression.
6054 * alloc.c (gdb_make_enums_visible): New constant. This ports to
6055 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
6056 Zaretskii in <http://bugs.gnu.org/12036#13>.
6057 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
6058 needed now that we have gdb_make_enums_visible.
6059 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
6060 (enum enum_USE_LSB_TAG):
6061 New enum types, packaging up enums that need to be exported to GDB.

6085 * lisp.h (struct Lisp_Excursion): New data type.
6086 (PVEC_EXCURSION): New pseudovector type.
6087 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
6088 to deal with it. Adjust comments.

6103 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
6104 emacs.c, as this is a more-suitable home. Had this been done earlier
6105 the fix for 12036 would have avoided some of the problems noted in
6106 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
6107 would have been more obvious.
6108 * emacs.c: Do not include <verify.h>; no longer needed.
6109 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
6110 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
6111 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

6117 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
6118 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
6119 not be usable in #if. This simplifies things.
6121 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
6123 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

6128 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
6129 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
6130 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
6131 Adjust to changes in lisp.h and emacs.c, by using
6132 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
6133 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
6134 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
6135 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
6136 instead of gdb_valbits.
6137 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
6138 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
6139 instead of gdb_array_mark_flag.
6140 (xboolvector): Get size from $->size, not $->header.size.
6141 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
6142 (xreload, hook-run, hookpost-run): Remove.
6143 * emacs.c: Include <verify.h>.
6144 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
6145 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
6147 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
6148 (gdb_USE_LSB_TAG): New enum constants.
6149 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
6150 Also define these as enum constants, so they're visible to GDB.
6151 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
6152 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
6153 as constants, so they're visible to GDB.

6156 Now enum constants, not macros, so they're visible to GDB.
6157 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
6158 more convenient now. All uses changed.
6159 (VALMASK) [USE_LSB_TAG]: Also define in this case.
6160 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
6162 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

6167 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
6169 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
6170 add argument, tune behavior, and adjust all callers.
6172 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
6174 Use typedef for EMACS_INT, EMACS_UINT.
6175 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
6176 than macros. This simplifies debugging in the usual case, since
6177 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
6178 and it allows expressions involving EMACS_INT casts.
6179 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
6181 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

6191 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
6193 Adjust buffer text indirection counters at the end of Fkill_buffer.
6194 * buffer.c (Fkill_buffer): Adjust indirection counters when the
6195 buffer is definitely dead. This should really fix an issue reported
6196 by Christoph Scholtes again. (Bug#12007).
6197 (init_buffer_once): Initialize indirection counters of
6198 buffer_defaults and buffer_local_symbols (for sanity and safety).
6200 2012-07-24 Eli Zaretskii <eliz@gnu.org>
6202 * xdisp.c (init_iterator): Don't compute dimensions of truncation
6203 and continuation glyphs on tooltip frames, leave them at zero.
6204 Avoids continued lines in tooltips. (Bug#11832)
6206 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
6208 Simplify copy_overlay.
6209 * buffer.c (copy_overlay): Simplify. Use build_marker.

6215 or invalid. (Bug#12025)
6217 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
6218 it signals an error when a tooltip frame is being created.
6220 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
6222 Cleanup miscellaneous objects allocation and initialization.

6229 (build_overlay): Add prototype.
6231 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
6233 Swap buffer text indirection counters in Fbuffer_swap_text.
6234 * buffer.c (Fbuffer_swap_text): Swap indirections too.
6235 This avoids crash reported by Christoph Scholtes at
6236 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
6238 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
6240 * nsmenu.m (Popdown_data): New struct.
6241 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
6243 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
6244 (initWithContentRect): Make imgView and contentView non-static
6245 and autorelease them. Also autorelease img and matrix (Bug#12005).
6246 (dealloc): Remove (Bug#12005).
6248 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
6250 Adjust consing_since_gc when objects are explicitly freed.
6251 * alloc.c (GC_DEFAULT_THRESHOLD): New macro.
6252 (Fgarbage_collect): Use it. Change minimum to 1/10 of default.
6253 (free_cons, free_misc): Subtract object size from consing_since_gc.
6255 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>

6259 (live_buffer, set_marker_internal): New function.
6260 (Fset_marker, set_marker_restricted): Use set_marker_internal.
6261 (set_marker_both, set_marker_restricted_both): Use live_buffer.
6263 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
6265 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
6266 as it's limited by the amount of memory, not by INT_MAX.
6268 2012-07-21 Eli Zaretskii <eliz@gnu.org>
6270 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
6271 in special-event-map. See the discussion at

6275 * w32menu.c (add_menu_item): Cast to ULONG_PTR when assigning
6276 info.dwItemData. Fixes crashes on 64-bit Windows.

6994 * s/aix4-2.h (unix): Remove; no longer needed.
6996 EMACS_TIME simplification (Bug#11875).
6997 This replaces macros (which typically do not work in GDB)
6998 with functions, typedefs and enums, making the code easier to debug.
6999 The functional style also makes code easier to read and maintain.
7000 * systime.h: Include <sys/time.h> on all hosts, not just if
7001 WINDOWSNT, since 'struct timeval' is needed in general.

7017 (add_emacs_time, sub_emacs_time): New functions.
7018 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

7041 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
7042 Prefer snprintf to strncpy.
7043 * nsterm.m (ns_term_init):
7044 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
7045 * nsterm.m (ns_term_init):
7046 Avoid the need for strncpy, by using build_string or
7047 make_unibyte_string directly. Use dtoastr, not snprintf.
7048 * process.c (Fmake_network_process): Diagnose service names that
7049 are too long, rather than silently truncating them or creating
7050 non-null-terminated names.
7051 (Fnetwork_interface_info): Likewise, for interface names.
7052 * sysdep.c (system_process_attributes) [GNU_LINUX]:
7053 Prefer sprintf to strncat.

7067 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
7068 where argument type is known to be a Lisp_Cons.

7123 O_RDONLY already includes it).
7125 Stop ns builds setting the EMACSLOADPATH environment variable.
7126 * nsterm.m (ns_load_path): Rename from ns_init_paths.
7127 Now it does not set EMACSLOADPATH, just returns the load-path string.
7128 * nsterm.h: Update accordingly.
7129 * lread.c [HAVE_NS]: Include nsterm.h.
7130 (init_lread) [HAVE_NS]: Use ns_load_path.

7140 (ns_init_paths): Do not set EMACSPATH.

7193 (ns_init_paths): Do not set EMACSDATA, EMACSDOC.
7194 * nsterm.h (ns_etc_directory): Add it.
7195 * callproc.c [HAVE_NS]: Include nsterm.h.
7196 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
7198 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7200 Move marker debugging code under MARKER_DEBUG.
7201 * marker.c (MARKER_DEBUG): Move marker debugging code under
7202 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
7203 for bootstrap with --enable-checking (~3x slowdown reported
7204 by Juanma Barranquero <lekktu@gmail.com>).
7205 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
7207 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
7209 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
7210 See <http://bugs.gnu.org/11825#29>.
7212 2012-07-08 Eli Zaretskii <eliz@gnu.org>
7214 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
7215 has no font, use the frame's font. (Bug#11813)
7216 (display_line): Add commentary about displaying truncation glyphs
7218 (produce_special_glyphs): Move here from term.c.
7220 * term.c (produce_special_glyphs): Move to xdisp.c.
7222 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
7225 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
7227 * xdisp.c (display_line): Avoid warning about implicit declaration
7230 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
7232 * lisp.h: Remove empty conditional.
7234 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
7236 * lread.c (load_path_check): Now static.
7238 Fix some minor --with-ns problems found by static checking.
7239 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
7240 (x_set_font) [!HAVE_X_WINDOWS]:
7241 * image.c (xpm_load_image) [HAVE_NS]:
7242 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
7243 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
7244 Remove unused local.
7245 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
7246 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
7247 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
7248 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
7249 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
7250 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
7251 Fix pointer signedness problem.
7252 * xfaces.c (FRAME_X_FONT_TABLE):
7253 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
7255 2012-07-07 Glenn Morris <rgm@gnu.org>
7257 * lread.c (load_path_check): New function, split from init_lread.
7258 (init_lread): Reorganize. Motivation:
7259 If EMACSLOADPATH is set, check/warn about that rather than the
7260 defaults, which we are not going to use. Hence we can remove
7261 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
7262 Don't warn if site-lisp directories are missing.
7263 If not installed, start from a blank load-path, since
7264 PATH_LOADSEARCH refers to the eventual installation directories.
7266 2012-07-07 Eli Zaretskii <eliz@gnu.org>
7268 Support truncation and continuation glyphs on GUI frames, when
7269 fringes are disabled. (Bug#11832)
7270 * xdisp.c (init_iterator): Get dimensions of truncation and
7271 continuation glyphs even if on GUI frames.
7272 Adjust it->last_visible_x on GUI frames when the left or right fringes,
7273 or both, are absent.
7274 (start_display, move_it_in_display_line_to): Handle the case of a
7275 GUI frame without a fringe to display continuation or truncation
7277 (insert_left_trunc_glyphs): Support GUI frames: make sure
7278 truncation glyphs overwrite enough glyphs from the current line to
7279 have sufficient space in pixels.
7280 (display_line): Support truncation and continuation glyphs on GUI
7281 frames. If some spare pixels are left on the line after inserting
7282 the truncation glyphs, fill that space with a stretch glyph of a
7283 suitably computed width.
7285 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
7286 produce_glyphs, to support GUI sessions.
7288 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
7290 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
7292 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
7294 Do not require float-time's arg to fit in time_t (Bug#11825).
7295 This works better on hosts where time_t is unsigned, and where
7296 float-time is applied to the (negative) difference between two times.
7297 * editfns.c (decode_time_components): Last arg is now double *,
7298 not int *, and means to store all the result as a double, without
7299 worrying about whether the seconds part fits in time_t.
7300 All callers changed.
7301 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
7302 All callers changed.
7303 (Ffloat_time): Do not fail merely because the specified time falls
7304 outside of time_t range.
7306 2012-07-07 Glenn Morris <rgm@gnu.org>
7308 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

7314 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
7315 Update dependencies.
7317 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
7319 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7321 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
7322 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
7323 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
7324 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
7325 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
7326 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
7328 * xfont.c (compare_font_names): Redo to omit the need for casts.
7330 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
7332 * xfns.c (Fx_change_window_property): Doc fix.
7333 * w32fns.c (Fx_change_window_property): Doc fix.
7335 * w32fns.c (Fx_window_property): Accept the same arguments as the
7336 X Windows version. Doc fix.
7337 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
7339 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
7340 Eli Zaretskii <eliz@gnu.org>
7342 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
7343 Windows-specific code from nt/config.nt moved here.
7344 Obsolete settings removed.
7346 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7348 * process.c: Avoid unnecessary calls to gettime.
7349 (wait_reading_process_output): Don't get the time of day
7350 when gobbling data immediately and not waiting, as there's no need
7351 for it in that case. This removes a FIXME.
7353 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
7355 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
7356 is defined (Bug#11768).
7358 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7360 Fix marker debugging code.
7361 * marker.c (byte_char_debug_check): Do not perform the check
7362 if buffer is not multibyte.
7363 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
7364 Call byte_char_debug_check with correct arguments.
7366 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7368 Compile marker debugging code only if ENABLE_CHECKING is defined.
7369 * marker.c (byte_char_debug_check, count_markers):
7370 Use only if ENABLE_CHECKING is defined.
7371 (byte_debug_flag): Remove.
7372 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
7373 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
7375 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7377 Avoid code repetition in marker-related functions.
7378 * marker.c (attach_marker): New function.
7379 (Fset_marker, set_marker_restricted, set_marker_both)
7380 (set_marker_restricted_both): Use it.
7381 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
7382 Consistently rename charno to charpos.
7383 (marker_position): Add eassert.
7384 (marker_byte_position): Convert to eassert.
7386 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

7396 * lisp.h (build_marker): New prototype.
7397 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
7398 * composite.c (autocmp_chars): Likewise.
7399 * editfns.c (buildmark): Remove.
7400 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
7401 (save_restriction_save): Use build_marker.
7402 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
7403 * window.c (save_window_save): Likewise.
7405 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7407 Do not use Fdelete_overlay in delete_all_overlays
7408 to avoid redundant calls to unchain_overlay.
7409 * buffer.c (drop_overlay): New function.
7410 (delete_all_overlays, Fdelete_overlay): Use it.
7411 * minibuf.c (get_minibuffer): Fix comment.
7413 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7415 Port to OpenBSD 5.1 amd64.
7416 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
7417 This is needed for OpenBSD, and should be harmless on all BSD systems.
7418 Also, include <sys/sysctl.h>, as it should be available on all
7419 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
7420 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
7421 use p_pid member, not kp_proc.pid.
7423 2012-07-06 Glenn Morris <rgm@gnu.org>
7425 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
7427 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
7429 More xmalloc and related cleanup.
7430 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
7431 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

7436 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
7437 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
7438 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
7440 Omit needless casts involving void * pointers and allocation.
7441 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
7442 as the former is more robust if P's type is changed.
7443 Prefer xzalloc to xmalloc + memset 0.
7444 Simplify malloc-or-realloc to realloc.
7445 Don't worry about xmalloc returning a null pointer.
7446 Prefer xstrdup to xmalloc + strcpy.
7447 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
7449 * keyboard.c (apply_modifiers_uncached): Prefer local array to
7450 alloca of a constant.
7452 2012-07-05 Eli Zaretskii <eliz@gnu.org>
7454 * xdisp.c (display_line): Fix horizontal pixel coordinates when
7455 hscroll is larger than the line width. Fixes long and futile
7456 looping inside extend_face_to_end_of_line (on a TTY) producing
7457 glyphs that are not needed and thrown away.
7459 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
7461 * marker.c (set_marker_restricted_both): Simplify by using
7464 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
7466 * editfns.c (region_limit): Simplify by using clip_to_bounds.
7468 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
7470 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is

7473 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
7474 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
7475 followed by gtk_box_set_homogeneous (Bug#11768).
7476 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
7477 (update_theme_scrollbar_width, xg_create_scroll_bar):
7478 Use gtk_scrollbar_new (Bug#11768).
7479 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
7480 (is_box_type): New function (Bug#11768).
7481 (xg_tool_item_stale_p): Call is_box_type.
7482 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
7483 with default display (Bug#11768).
7485 2012-07-05 Eli Zaretskii <eliz@gnu.org>
7487 * xdisp.c (window_hscroll_limited): New function.
7488 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
7489 coordinates when window's hscroll is set to insanely large
7492 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
7494 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
7495 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
7497 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
7500 * lisp.h (xzalloc): New prototype. Omit needless casts.
7501 * alloc.c (xzalloc): New function. Omit needless casts.

7553 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
7555 * fileio.c (time_error_value): Check the right error number.
7556 Problem reported by Troels Nielsen in
7557 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
7559 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7561 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
7562 This should be fixed in a better way; see Eli Zaretskii in
7563 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
7564 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
7566 * fileio.c (time_error_value): Rename from special_mtime.
7567 The old name's problems were noted by Eli Zaretskii in
7568 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
7570 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
7571 This variable's comment says Emacs needs at least one GDB-visible
7572 symbol of type enum pvec_type, to work around GDB problems.
7573 The symbol's value doesn't matter.
7575 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
7576 that causes compilation to fail on pre-C99 compilers.
7578 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
7580 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
7581 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
7583 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
7585 * buffer.c (init_buffer_once): Fix initialization of
7586 headers for buffer_defaults and buffer_local_symbols.
7587 Reported by Juanma Barranquero <lekktu@gmail.com>.
7589 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
7591 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
7592 * lisp.h (enum pvec_type): Use fewer bits.
7593 (PSEUDOVECTOR_SIZE_BITS): New constant.
7594 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
7595 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
7596 change in pvec_type.
7597 (PSEUDOVECTOR_TYPEP): New macro.
7598 (TYPED_PSEUDOVECTORP): Use it.
7599 * fns.c (internal_equal): Adapt code to extract pvectype.
7600 * emacs.c (gdb_pvec_type): Update type.
7601 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
7602 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
7603 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
7604 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
7605 (sweep_vectors): Use it. Use local var `total_bytes' instead of
7606 abusing vector->header.next.nbytes.
7607 (live_vector_p): Use PVEC_TYPE.
7608 (mark_object): Adapt code to extract pvectype. Use switch.
7610 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7612 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
7613 Tighten new eassert a bit.
7615 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
7617 Fix compilation with --enable-gcc-warnings and -O1
7619 * doprnt.c (doprnt): Change type of tem to int, initialize
7620 to avoid compiler warning. Add eassert.
7621 * search.c (simple_search): Initialize match_byte to avoid
7622 compiler warning. Add eassert.
7624 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7626 Avoid weird behavior with large horizontal scrolls.
7627 Without this change, for example, large hscroll values would
7628 mess up Emacs's display on Fedora 15 x86, presumably due to
7629 overflows in int calculations in the display code.
7630 Also, if buffers had long lines, Emacs would freeze.
7631 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
7632 (set_window_hscroll): New function, containing the old guts of
7633 Fset_window_hscroll. Return the clipped value.
7634 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
7635 This avoids the need to check against PTRDIFF_MAX.
7637 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
7639 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
7641 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.

7645 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
7646 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
7647 since GCC 4.4.6 issues a bogus warning for them.
7649 Fix bugs in file timestamp newness comparisons.
7650 * fileio.c (Ffile_newer_than_file_p):
7651 * lread.c (Fload): Use full timestamp resolution of files,
7652 not just the 1-second resolution, so that files that are only
7653 slightly newer still count as newer.
7654 * fileio.c (Ffile_newer_than_file_p): Don't assume file
7655 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
7657 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
7659 * fileio.c: Improve handling of file time marker. (Bug#11852)
7660 (special_mtime): New function.
7661 (Finsert_file_contents, Fverify_visited_file_modtime):
7662 Use it to set special mtime values consistently.
7664 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
7666 * fileio.c (Finsert_file_contents): Properly handle st_mtime
7667 marker for non-existing file. (Bug#11852)
7669 2012-07-03 Glenn Morris <rgm@gnu.org>
7671 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
7672 and did not make it into globals.h).
7674 2012-07-03 Tom Tromey <tromey@redhat.com>
7676 * window.c (Fset_window_margins, Fset_window_fringes)
7677 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
7678 * textprop.c (Fprevious_property_change): No longer static.

7702 * fontset.h: Remove EXFUN.
7703 * font.h: Remove EXFUNs.
7704 * dosfns.c (system_process_attributes): Remove EXFUN.

7720 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
7721 values which aren't power of 2.
7722 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
7723 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
7726 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
7728 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
7730 * alloc.c (mark_object): Revert part of last patch to use `switch'.
7732 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7734 * alloc.c (allocate_vector_block): Remove redundant
7735 calls to mallopt if DOUG_LEA_MALLOC is defined.
7736 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
7737 avoid calls to mallopt if zero_vector is returned.
7739 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7741 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
7742 is enabled, avoid dereferencing NULL current_sblock if
7745 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7747 Cleanup basic buffer management.
7748 * buffer.h (struct buffer): Change layout to use generic vector
7749 marking code. Fix some comments. Change type of 'clip_changed'
7750 to bitfield. Remove unused #ifndef old.
7751 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
7752 (GET_OVERLAYS_AT): Fix indentation.
7753 (for_each_per_buffer_object_at): New macro.
7754 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
7755 (Fbuffer_local_variables): Use it.
7756 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
7757 * alloc.c (allocate_buffer): Adjust to match new layout of
7758 struct buffer. Fix comment.
7759 (mark_overlay): New function.
7760 (mark_buffer): Use it. Use mark_vectorlike to mark normal
7761 Lisp area of struct buffer.
7762 (mark_object): Use it. Adjust marking of misc objects
7763 and related comments.
7765 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
7767 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
7768 wrapper that is not needed because the wrapped code is a no-op (zero
7769 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
7770 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
7772 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
7774 * alloc.c (mark_buffer): Simplify. Remove prototype.
7775 (mark_object): Add comment. Reorganize marking of vector-like
7776 objects. Use CHECK_LIVE for all vector-like objects except buffers
7777 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
7778 Avoid redundant calls to mark_vectorlike for bool vectors.
7780 2012-06-30 Glenn Morris <rgm@gnu.org>
7782 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
7784 * epaths.in (PATH_SITELOADSEARCH): New.
7785 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
7786 This is rather than relying on --enable-locallisppath elements
7787 having "site-lisp" in their names. (Bug#10208#25, 11658)
7789 2012-06-30 Eli Zaretskii <eliz@gnu.org>
7791 * w32proc.c (sys_select): Accept and ignore one more argument.
7793 * w32.c (emacs_gnutls_pull): Call select with one more argument.
7795 * sysselect.h [DOS_NT]: Don't include sys/select.h.
7796 (pselect) [!MS_DOS]: Redirect to sys_select.
7798 * sysdep.c: Don't include dos.h and dosfns.h.
7800 * process.c (sys_select):
7801 * msdos.c (sys_select): Accept one more argument and ignore it.
7803 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
7804 adapt data types and code to that.
7807 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
7808 which clashes with the gnulib function of the same name.
7810 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
7812 * font.c (font_style_to_value, font_style_symbolic)
7813 (font_prop_validate_style): Add type checks for values in
7816 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
7818 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
7821 2012-06-29 Eli Zaretskii <eliz@gnu.org>
7823 * xdisp.c (try_window_id): Undo last change.
7825 * w32.c (getwd): Adjust commentary about startup_dir.
7826 (init_environment): Always call sys_access, even in non-MSVC
7827 builds. Don't chdir to the directory of the Emacs executable.
7828 This undoes code from 1997 which was justified by the need to
7829 "avoid conflicts when removing and renaming directories". But its
7830 downside was that every relative file name was being interpreted
7831 relative to the directory of the Emacs executable, which can never
7832 be TRT. In particular, it broke sys_access when called with
7833 relative file names.
7834 (sys_access): Map GetLastError to errno.
7836 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
7838 * window.h (struct window): Change type of 'fringes_outside_margins'
7839 to bitfield. Fix comment. Adjust users accordingly.

7842 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
7845 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>

7848 Add QUIT to make the loop interruptible.
7850 2012-06-29 Glenn Morris <rgm@gnu.org>
7852 * charset.c (init_charset): Make lack of etc/charsets fatal.
7854 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
7856 * editfns.c (region_limit): Fix type mismatch.
7858 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
7860 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
7861 undefined. Convert from xassert to eassert.
7862 * nsmenu.m: Convert from xassert to eassert.
7863 * nsterm.m: Likewise.
7865 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
7867 * editfns.c (region_limit): Clip to narrowing (bug#11770).
7869 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
7871 Avoid integer overflow on scroll-left and scroll-right.
7872 * window.c (HSCROLL_MAX): New macro.
7873 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
7874 overflow when requested scroll falls outside ptrdiff_t range.
7876 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
7878 * window.h (struct window): Change type of 'hscroll',
7879 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
7880 'last_modified' and 'last_overlay_modified' to EMACS_INT.
7881 Adjust users accordingly.
7882 * xdisp.c (try_cursor_movement): Replace type check with eassert.
7883 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
7884 from EMACS_INT to ptrdiff_t.
7885 (make_window): Omit redundant initialization.
7887 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

7891 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
7893 * window.h (struct window): Change type of 'use_time' and
7894 'sequence_number' from Lisp_Object to int.

7960 * alloc.c (allocate_string): Omit intervals initialization.
7961 * alloc.c (make_uninit_multibyte_string): Initialize intervals
7962 as in make_pure_string and make_pure_c_string.

7966 * alloc.c (allocate_string): Fix last change.
7968 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

8018 * alloc.c: Remove build_string.
8019 * lisp.h: Define build_string as static inline. This provides
8020 a better opportunity to optimize away calls to strlen when the
8021 function is called with compile-time constant argument.
8022 * image.c (imagemagick_error): Convert to build_string.
8023 * w32proc.c (sys_spawnve): Likewise.
8024 * xterm.c (x_term_init): Likewise.
8026 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
8028 Use sprintf return value instead of invoking strlen on result.
8029 In the old days this wasn't portable, since some sprintf
8030 implementations returned char *. But they died out years ago and
8031 Emacs already assumes sprintf returns int.
8032 Similarly for float_to_string.
8033 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
8034 * ccl.c (ccl_driver):
8035 * character.c (string_escape_byte8):

8040 * xfns.c (syms_of_xfns):
8041 Use sprintf or float_to_string result to avoid need to call strlen.
8042 * data.c (Fnumber_to_string):
8043 Use make_unibyte_string, since the string must be ASCII.
8044 * lisp.h, print.c (float_to_string): Now returns int length.
8045 * term.c (produce_glyphless_glyph):
8046 Use sprintf result rather than recomputing it.
8048 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
8049 * Makefile.in (ALL_CFLAGS):
8050 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

8081 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

8086 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
8087 instead of truncating it to 63 (admittedly a generous limit).
8089 * process.c: Fix spelling and caps in comments.
8091 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
8093 * emacs.c (setpgrp): Remove definition, unused.

8217 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
8219 Support higher-resolution time stamps (Bug#9000).
8220 The time stamps are only nanosecond-resolution at the C level,
8221 since that's the best that any real-world system supports now.
8222 But they are picosecond-resolution at the Lisp level, as that's
8223 easy, and leaves room for future OS improvements.
8225 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
8228 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
8229 Don't get current time unless it's needed.
8231 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
8232 now provides it if it's absent.
8233 (start_atimer): Port to higher-res time stamps.
8234 Check for time stamp overflow. Don't get current time more
8235 often than is needed.
8237 * buffer.h (struct buffer): Buffer modtime now has high resolution.
8238 Include systime.h, not time.h.
8239 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
8241 * dired.c: Include stat-time.h.
8242 (Ffile-attributes): File times now have higher resolution.
8244 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
8245 (struct image): Timestamp now has higher resolution.
8247 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
8248 has at least microseconds now. All uses removed.
8249 (update_frame, update_single_window, update_window, update_frame_1)
8250 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
8251 (duration_to_sec_usec): Remove; no longer needed.
8253 * editfns.c (time_overflow): Now extern.

8258 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
8259 (decode_time_components, lisp_seconds_argument): New functions.
8260 (make_time): Now static.
8261 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
8262 Report an error if the time is invalid, rather than having the caller
8265 * fileio.c: Include <stat-time.h>
8266 (Fcopy_file): Copy higher-resolution time stamps.
8267 Prefer to set the time stamp via a file descriptor if that works.

8269 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
8270 (Fvisited_file_modtime, Fset_visited_file_modtime):
8271 Support higher-resolution time stamps.
8273 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
8275 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
8277 * image.c (prepare_image_for_display, clear_image_cache)
8278 (lookup_image): Port to higer-resolution time stamps.
8280 * keyboard.c (start_polling, bind_polling_period):
8281 Check for time stamp overflow.
8282 (read_char, kbd_buffer_get_event, timer_start_idle)
8283 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
8284 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
8285 Port to higher-resolution time stamps. Do not assume time_t is signed.
8286 (decode_timer): New function. Timers are now vectors of length 9,
8287 not 8, to accommodate the picosecond component.
8288 (timer_check_2): Use it.
8290 * nsterm.m (select_timeout, timeval_subtract): Remove.
8291 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
8292 as they're a bit more accurate and handle overflow better.
8293 (ns_select): Change prototype to be compatible with pselect.
8294 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
8295 * nsterm.h (ns_select): Adjust prototype.
8297 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
8298 us-resolution time stamps.
8299 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
8301 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
8303 * lisp.h (time_overflow): New decl.
8304 (wait_reading_process_output): First arg is now intmax_t, not int,
8305 to accommodate larger waits.
8307 * process.h (struct Lisp_Process.read_output_delay):
8308 Now counts nanoseconds, not microseconds.
8309 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about

8312 (wait_reading_process_output):
8313 Port to ns-resolution time stamps.
8314 (Faccept_process_output, wait_reading_process_output):
8315 Check for time stamp overflow. Do not assume time_t is signed.
8316 (select_wrapper): Remove; we now use pselect.
8317 (Fprocess_attributes): Now generates ns-resolution time stamps.
8319 * sysdep.c: Include utimens.h. Don't include utime.h
8320 or worry about struct utimbuf; gnulib does that for us now.
8321 (gettimeofday): Remove; gnulib provides a substitute.
8322 (make_timeval): New function.
8323 (set_file_times): Now sets ns-resolution time stamps.
8324 New arg FD; all uses changed.
8325 (time_from_jiffies, ltime_from_jiffies, get_up_time)
8326 (system_process_attributes):
8327 Now returns ns-resolution time stamp. All uses changed.
8328 Check for time stamp overflow.
8330 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
8331 provides a substitute now.
8333 * systime.h: Include timespec.h rather than sys/time.h and time.h,
8334 since it guarantees struct timespec.
8335 (EMACS_TIME): Now struct timespec, so that we can support
8336 ns-resolution time stamps.
8337 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
8338 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
8339 (EMACS_USECS): Remove.
8340 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
8341 so multiply the arg by 1000 before storing it.
8342 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
8344 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
8345 Port to ns-resolution time stamps.
8346 (EMACS_TIME_NEG_P): Remove; replaced by....
8347 (EMACS_TIME_SIGN): New macro.
8348 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
8349 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
8350 (set_file_times, make_time, lisp_time_argument): Adjust signature.
8351 (make_timeval, make_lisp_time, decode_time_components): New decls.
8352 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
8353 that it mishandled time_t overflow. You can't compare by subtracting!
8354 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
8355 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
8357 * term.c: Include <sys/time.h>.
8358 (timeval_to_Time): New function, for proper overflow wraparound.

8363 (Fprimitive_undo): Use them when restoring time stamps.
8365 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
8366 (w32_get_internal_run_time):
8367 Port to higher-resolution Emacs time stamps.
8368 (ltime): Now accepts single 64-bit integer, as that's more convenient
8371 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
8373 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
8374 for compatibility with pselect. Support ns-resolution time stamps.
8376 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
8378 * xselect.c (wait_for_property_change, x_get_foreign_selection):
8379 Check for time stamp overflow, and support ns-resolution time stamps.
8381 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
8382 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
8383 (timeval_subtract): Remove; no longer needed.
8384 (XTflash, XTring_bell, x_wait_for_event):
8385 Port to ns-resolution time stamps. Don't assume time_t is signed.
8387 2012-06-22 Chong Yidong <cyd@gnu.org>

8391 2012-06-22 Eli Zaretskii <eliz@gnu.org>
8393 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
8394 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
8395 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
8396 staticidx goes up to 1597 out of 1600 = 0x640.)
8398 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
8400 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
8401 Otherwise, the umask might be mistakenly 0 while handling input signals.

8415 2012-06-19 Chong Yidong <cyd@gnu.org>
8417 * frame.c (delete_frame): When selecting a frame on a different

8423 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
8425 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
8426 since tty frames can be explicitly named.

8434 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
8435 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
8436 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
8437 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
8438 (METER_1, METER_2): Simplify.
8440 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>

8444 2012-06-18 Martin Rudalics <rudalics@gmx.at>
8446 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
8447 gets killed during executing of this function (Bug#11665).
8448 Try to always return Qt when the buffer has been actually killed.
8449 (Vkill_buffer_query_functions): In doc-string say that functions
8450 run by this hook should not change the current buffer.
8452 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
8454 Fix recently-introduced process.c problems found by static checking.

8472 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
8474 * lisp.h (eassert): Assume C89 or later.
8475 This removes the need for CHECK.
8476 (CHECK): Remove. Its comments about always evaluating its
8477 argument were confusing, as 'eassert' typically does not evaluate
8480 * coding.c (produce_chars): Use ptrdiff_t, not int.
8482 * xterm.c (x_draw_underwave): Check for integer overflow.
8483 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

8577 If all the glyphs of the glyph row came from strings, and we have no
8578 cursor positioning clues, put the cursor on the first glyph of the

8621 * s/bsd-common.h (BSD4_3):
8622 * s/usg5-4-common.h (USG5_4): No longer define; unused.
8624 2012-06-13 Andreas Schwab <schwab@linux-m68k.org>
8626 * lisp.h (Lisp_Object) [CHECK_LISP_OBJECT_TYPE]: Define as struct
8629 (XHASH, XTYPE, XINT, XUINT, make_number, XSET, XPNTR, XUNTAG):
8631 * emacs.c (gdb_use_struct): Rename from gdb_use_union.
8632 * .gdbinit: Check gdb_use_struct instead of gdb_use_union.
8633 * alloc.c (widen_to_Lisp_Object): Remove.
8634 (mark_memory): Use XIL instead of widen_to_Lisp_Object.
8635 * frame.c (delete_frame): Remove outdated comment.
8636 * w32fns.c (Fw32_register_hot_key): Use XLI instead of checking
8637 USE_LISP_UNION_TYPE.

8639 (Fw32_toggle_lock_key): Likewise.
8640 * w32menu.c (add_menu_item): Likewise.
8641 (w32_menu_display_help): Use XIL instead of checking
8642 USE_LISP_UNION_TYPE.
8643 * w32heap.c (allocate_heap): Don't check USE_LISP_UNION_TYPE.

8652 * s/gnu.h (POSIX_SIGNALS): Remove (not used since 2010-05-04).
8654 2012-06-13 Paul Eggert <eggert@cs.ucla.edu>
8656 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
8657 * alloc.c (make_number) [!defined make_number]:
8658 Remove, as lisp.h always defines this now.

8660 (roundup_size): Verify that it is a power of 2.
8661 * data.c (Fmake_variable_buffer_local, Fmake_local_variable):
8662 * ftfont.c (ftfont_driver): Use LISP_INITIALLY_ZERO.
8663 * lisp.h (USE_LSB_TAG): Allow the builder to compile with

8665 USE_LSB_TAG now is always defined to be either 0 or 1.
8667 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
8668 code works fine either way, and efficiency is not a concern here,
8669 as the union type is for debugging, not for production.
8670 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
8671 Use an inline function on all platforms when using the union type,
8672 since this is simpler and 'static inline' can be used portably
8674 (LISP_INITIALLY_ZERO): New macro.
8675 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
8676 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

8703 * s/gnu-kfreebsd.h, s/gnu-linux.h, s/gnu.h, s/hpux10-20.h:
8704 * s/irix6-5.h, s/ms-w32.h, s/msdos.h, s/template.h:
8705 * s/usg5-4-common.h: Move SYSTEM_TYPE to configure.
8707 2012-06-11 Stefan Monnier <monnier@iro.umontreal.ca>
8709 * alloc.c (make_byte_code): New function.

8715 * image.c (imagemagick_load_image): Implement transparency.
8717 2012-06-10 Andreas Schwab <schwab@linux-m68k.org>
8719 * regex.c (at_begline_loc_p): Also recognize `(?N:' and correctly
8720 account for preceding backslashes. (Bug#11663)
8722 2012-06-09 Chong Yidong <cyd@gnu.org>

8744 * dbusbind.c (XD_BASIC_DBUS_TYPE): Use dbus_type_is_valid and
8745 dbus_type_is_basic if available.
8746 (xd_extract_signed, xd_extract_unsigned): Rename from
8747 extract_signed and extract_unsigned, respectively. Adapt callers.
8749 2012-06-09 Chong Yidong <cyd@gnu.org>
8751 * xfaces.c (face_for_overlay_string): Handle face remapping (Bug#2066).

8758 * xdisp.c (vmessage): Treat frame message as multibyte.
8759 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
8760 would generate the diagnostic "Making \302\247 buffer-local while
8763 2012-06-08 Eli Zaretskii <eliz@gnu.org>
8765 * dispnew.c (showing_window_margins_p): Undo last change, which

8776 2012-06-08 Juanma Barranquero <lekktu@gmail.com>
8778 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
8779 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
8781 2012-06-08 Eli Zaretskii <eliz@gnu.org>
8783 * alloc.c (allocate_vectorlike): Fix last change.
8785 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
8787 Block-based vector allocation of small vectors.
8788 * lisp.h (struct vectorlike_header): New field `nbytes',
8789 adjust comment accordingly.
8790 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
8791 to denote vector blocks. Adjust users (live_vector_p,
8792 mark_maybe_pointer, valid_lisp_object_p) accordingly.

8812 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
8814 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
8816 * doprnt.c (doprnt): Truncate multibyte char correctly.
8817 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
8818 would mishandle a string argument "Xc" if X was a multibyte
8819 character of length 2: it would truncate after X's first byte
8820 rather than including all of X.
8822 2012-06-06 Chong Yidong <cyd@gnu.org>
8824 * buffer.c (word_wrap): Doc fix.
8826 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

8873 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
8874 Convert pctcpu and pctmem to Lisp float properly.
8875 Let the compiler fold better, as 100.0/0x8000 is exact.
8877 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
8879 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
8882 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
8884 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
8886 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
8888 For a 'struct window', replace some Lisp_Object fields to
8889 bitfields where appropriate, remove unused fields.
8890 * window.h (struct window): Remove unused 'last_mark_x' and
8891 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
8892 change its type from Lisp_Object to bitfield.
8893 Change type of 'force_start', 'optional_new_start',
8894 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
8895 fields from Lisp_Object to bitfield. Adjust users accordingly.
8897 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
8899 Pacify gcc -Wdouble-precision when using Xaw.
8900 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
8901 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
8902 Use 'float' consistently, rather than 'float' in most places
8903 and 'double' in a couple of places.
8905 2012-05-31 Eli Zaretskii <eliz@gnu.org>
8907 * xdisp.c (handle_stop): Detect whether we have overlay strings
8908 loaded by testing it->current.overlay_string_index to be
8909 non-negative, instead of checking whether n_overlay_strings is
8910 positive. (Bug#11587)
8912 2012-05-31 Chong Yidong <cyd@gnu.org>
8914 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
8916 * doc.c (Fsubstitute_command_keys): Doc fix.
8918 2012-05-31 Eli Zaretskii <eliz@gnu.org>
8920 * search.c (search_buffer): Remove calls to
8921 r_alloc_inhibit_buffer_relocation, as it is now called by
8922 maybe_unify_char, which was the cause of relocation of buffer text
8925 2012-05-31 Eli Zaretskii <eliz@gnu.org>
8927 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
8928 for the duration of call to load_charset, to avoid problems with
8929 callers of maybe_unify_char that access buffer text through C
8932 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
8933 decrement the inhibition flag, instead of just setting or
8936 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
8938 Remove obsolete '#define static' cruft.
8939 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
8940 This #undef was "temporary" in 2000; it is no longer needed
8941 now that '#define static' has gone away.
8942 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
8943 (gray_bitmap_bits): Remove; no longer needed.
8944 All uses replaced with definiens.
8945 * xterm.c: Include "bitmaps/gray.xbm".
8947 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
8949 Clean up __executable_start, monstartup when --enable-profiling.
8950 The following changes affect the code only when profiling.
8951 * dispnew.c (__executable_start): Rename from safe_bcopy.
8952 Define only on platforms that need it.
8953 * emacs.c: Include <sys/gmon.h> when profiling.
8954 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
8955 (__executable_start): Remove decl, since lisp.h does it now.
8956 (safe_bcopy): Remove decl; no longer has that name.
8957 (main): Coalesce #if into single bit of code, for simplicity.
8958 Cast pointers to uintptr_t, since standard libraries want integers

8985 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
8987 Do not create empty overlays with the evaporate property (Bug#9642).
8988 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
8989 Bug#9642, but explicitly check that the buffer the overlay would
8990 be moved to is live and rearrange lines to make sure that errors
8991 will not put the overlay in an inconsistent state.
8992 (Fdelete_overlay): Cosmetics.
8994 2012-05-28 Eli Zaretskii <eliz@gnu.org>
8996 * w32term.c (my_bring_window_to_top): New function.
8997 (x_raise_frame): Use handle returned by DeferWindowPos, which

9008 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
9010 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
9011 This avoids undefined behavior that might cause the eassert
9012 to not catch an out-of-range value.
9014 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
9016 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

9028 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
9030 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
9031 Only r_alloc_inhibit_buffer_relocation needed to be added;
9032 the others were already declared.
9034 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
9035 before checking whether it's out of range. Put the check inside
9037 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
9039 2012-05-27 Ken Brown <kbrown@cornell.edu>
9041 * callproc.c (Fcall_process): Restore a line that was accidentally
9042 commented out in the 2011-02-13 change (bug#11547).

9046 * lisp.h [REL_ALLOC]: Add prototypes for external functions
9047 defined on ralloc.c.
9049 * buffer.c [REL_ALLOC]: Remove prototypes of
9050 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
9051 they are now on lisp.h.
9053 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
9055 * search.c (search_buffer): Use it to inhibit relocation of buffer
9056 text while re_search_2 is doing its job, because re_search_2 is
9057 passed C pointers to buffer text. (Bug#11519)
9059 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
9062 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
9063 state after an additional call to move_it_in_display_line_to, keep
9064 the values of it->max_ascent and it->max_descent found for the
9066 (pos_visible_p): Revert the comparison against bottom_y to what it
9067 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
9070 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
9072 Fix coding-related core dumps with gcc -ftrapv.
9073 The code was computing A - B, where A and B are pointers, and B is
9074 random garbage. This can lead to core dumps on platforms that
9075 have special pointer registers, and it also leads to core dumps on
9076 x86-64 when compiled with gcc -ftrapv. The fix is to compute
9077 A - B only when B is initialized properly.
9078 * coding.c (coding_set_source, coding_set_destination): Return void.
9079 (coding_change_source, coding_change_destinations): New functions,
9080 with the old behaviors of coding_set_source and coding_set_destination.
9081 All callers that need an offset changed to use these new functions.
9083 2012-05-26 Glenn Morris <rgm@gnu.org>
9085 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
9087 2012-05-26 Eli Zaretskii <eliz@gnu.org>
9089 Extend mouse support on W32 text-mode console.
9090 * xdisp.c (draw_row_with_mouse_face):

9105 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
9107 * lread.c (read1): Simplify slightly to avoid an overflow warning
9108 with GCC 4.7.0 on x86-64.
9110 2012-05-26 Eli Zaretskii <eliz@gnu.org>
9112 * bidi.c (bidi_mirror_char): Revert last change: an int is
9113 definitely wide enough here.
9115 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
9117 Fix integer width and related bugs (Bug#9874).

9129 Use int, not EMACS_INT, where int is wide enough.

9149 (Foverlay_recenter, last_overlay_modification_hooks_used)
9150 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
9151 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9152 (validate_region): Omit unnecessary test for b <= e,
9153 since that's guaranteed by the previous test.
9154 (adjust_overlays_for_delete): Avoid pos + length overflow.
9155 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
9156 (report_overlay_modification):
9157 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9158 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):

9167 not int, to avoid needless 32-bit limit on 64-bit hosts.
9168 (exec_byte_code): Use tighter memory-full test, one that checks
9169 for alloca overflow. Don't compute the address of the object just
9170 before an array, as that's not portable. Use EMACS_INT, not
9171 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
9172 * callint.c (Fcall_interactively):
9173 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

9186 (casify_object): Avoid integer overflow when overallocating buffer.
9187 * casetab.c (set_identity, shuffle): Prefer int to unsigned when

9190 * category.h (CATEGORYP): Don't assume arg is nonnegative.
9191 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the

9194 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9195 For CCL_MapSingle, check that content and value are in int range.

9197 Check that Vcode_version_map_vector is a vector.
9198 (resolve_symbol_ccl_program): Check that vector header is in range.
9199 Always copy the vector, so that we can check its contents reliably
9200 now rather than having to recheck each instruction as it's being
9201 executed. Check that vector words fit in 'int'.
9202 (ccl_get_compiled_code, Fregister_ccl_program)
9203 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
9204 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

9206 contents are in range.
9207 (Fccl_execute_on_string): Check that status is in range.
9208 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
9209 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
9210 Accept and return EMACS_INT, not int, because callers can pass values

9217 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

9219 avoid mishandling large integers.

9230 Don't rely on undefined behavior with signed left shift overflow.
9231 Don't assume unsigned int fits into fixnum, or that fixnum fits
9232 into unsigned int. Don't require max_code to be a valid fixnum;
9233 that's not true for gb10830 4-byte on a 32-bit host. Allow
9234 invalid_code to be a cons, for the same reason. Require code_offset
9235 to be a character. Avoid int overflow if max_char is close
9237 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
9238 this is intended anyway and avoids some undefined behavior.
9239 (load_charset_map): Pass unsigned, not int, as 2nd arg of
9240 INDEX_TO_CODE_POINT, as that's what it expects.
9241 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
9242 * charset.h (DECODE_CHAR): Return int, not unsigned;
9243 this is what was intended anyway, and it avoids undefined behavior.
9244 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
9245 integer-overflow issues.
9246 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
9247 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
9248 where the argument is EMACS_INT, and this behavior is not intended.
9249 * chartab.c (Fmake_char_table, Fset_char_table_range)
9250 (uniprop_get_decoder, uniprop_get_encoder):
9251 Don't assume fixnum fits in int.
9252 * cmds.c (move_point): New function, that does the gist of
9253 Fforward_char and Fbackward_char, but does so while checking
9254 for integer overflow more accurately.
9255 (Fforward_char, Fbackward_char): Use it.
9256 (Fforward_line, Fend_of_line, internal_self_insert)
9257 (internal_self_insert):
9258 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

10028 (Fword_search_forward_lax): Move functions to isearch.el

10031 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
10033 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
10035 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
10037 * lread.c (init_obarray): Declare Qt and Qnil as special.
10039 2012-05-14 Glenn Morris <rgm@gnu.org>
10041 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
10042 Put "libexec" before "bin", for the sake of init_callproc_1.
10044 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
10046 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
10048 * unexaix.c: Port to more-recent AIX compilers.
10049 (report_error, report_error_1, make_hdr, copy_sym)
10050 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
10051 Make arguments const char *, not char *, to avoid violations of C
10052 standard and to fix some AIX warnings reported by Gilles Pion.
10054 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10056 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
10057 already have overlays loaded.
10058 (handle_single_display_spec): Before returning without displaying
10059 fringe bitmap, synchronize the bidi iterator with the main display
10060 iterator, by calling iterate_out_of_display_property.
10061 (iterate_out_of_display_property): Detect buffer iteration by
10062 testing that it->string is a Lisp string.
10063 (get_next_display_element): When the current object is exhausted,
10064 and there's something on it->stack, call set_iterator_to_next to
10065 proceed with what's on the stack, instead of returning zero.
10066 (set_iterator_to_next): If called at the end of a Lisp string,
10067 proceed to consider_string_end without incrementing string
10068 position. Don't increment display vector index past the end of
10069 the display vector. (Bug#11417)
10070 (pos_visible_p): Don't report a position visible when move_it_to
10071 stopped at the last line of window, which happens to be scanned
10072 backwards by the bidi iteration. (Bug#11464)
10074 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10076 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
10077 and right-margin display specs even if the spec is invalid or we
10078 are on a TTY, and thus unable to display on the fringes.
10079 That's because the text with the property will not be displayed anyway,
10080 so we need to signal to the caller that this is a "replacing"
10081 display spec. This fixes display when the spec is invalid or we
10084 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
10086 * unexaix.c (make_hdr): Fix typo in prototype.
10087 This bug broke the build on AIX. Problem reported by Gilles Pion.
10089 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
10091 * keyboard.c (kbd_buffer_get_event): Read special events also in
10092 batch mode. (Bug#11415)
10094 2012-05-12 Glenn Morris <rgm@gnu.org>
10096 * ns.mk: Update for ns_appbindir no longer having trailing "/".
10098 2012-05-12 Eli Zaretskii <eliz@gnu.org>
10100 * lisp.mk (lisp): Add newcomment.elc.
10102 2012-05-12 Glenn Morris <rgm@gnu.org>
10104 * Makefile.in (MKDIR_P): New, set by configure.
10105 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
10107 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
10109 Remove unused function hourglass_started.
10110 * dispextern.h (hourglass_started):
10111 * w32fns.c (hourglass_started):
10112 * xdisp.c (hourglass_started): Remove.

10117 Update dependencies.
10119 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
10121 * xgselect.c (xg_select): Put maxfds+1 into a var.
10122 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
10124 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
10126 2012-05-10 Dave Abrahams <dave@boostpro.com>
10128 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
10129 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
10131 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
10133 * dbusbind.c (xd_registered_buses): New internal Lisp object.
10134 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
10135 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
10136 Initialize xd_registered_buses.
10138 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
10140 Untag more efficiently if USE_LSB_TAG.
10141 This is based on a proposal by YAMAMOTO Mitsuharu in
10142 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
10143 For an admittedly artificial (nth 8000 longlist) benchmark on
10144 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
10145 Emacs's overall text size by 1%.
10146 * lisp.h (XUNTAG): New macro.
10147 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
10148 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
10149 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
10150 * eval.c (Fautoload):
10151 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
10152 * frame.h (XFRAME): Use XUNTAG.
10154 Port recent dbusbind.c changes to 32-bit --with-wide-int.
10155 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
10156 Remove unportable assumptions about print widths of types like
10158 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
10159 intptr_t when converting between pointer and integer, to avoid GCC
10160 warnings about wrong width.
10162 2012-05-09 Eli Zaretskii <eliz@gnu.org>
10164 * w32proc.c (new_child): Force Windows to reserve only 64KB of
10165 stack for each reader_thread, instead of defaulting to 8MB
10166 determined by the linker. This avoids failures in creating
10167 subprocesses on Windows 7, see the discussion in this thread:
10168 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
10170 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
10172 Fix up display of the *Minibuf-0* buffer in the mini window.
10173 * keyboard.c (read_char): Don't clear the echo area if there's no
10175 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
10176 contents of *Minibuf-0*) if there's no message displayed in its stead.
10178 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
10180 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
10183 2012-05-06 Chong Yidong <cyd@gnu.org>
10185 * lisp.mk (lisp): Update.
10187 2012-05-05 Jim Meyering <meyering@redhat.com>
10189 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
10191 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
10193 * data.c (PUT_ERROR): New macro.
10194 (syms_of_data): Use it. Add new error type `user-error'.
10195 * undo.c (user_error): New function.
10196 (Fprimitive_undo): Use it.
10197 * print.c (print_error_message): Adjust print style for `user-error'.
10198 * keyboard.c (user_error): New function.
10199 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
10201 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
10203 Do not limit current-time-string to years 1000..9999.
10204 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
10205 (Fcurrent_time_string): Support any year that is supported by the
10206 underlying localtime representation. Don't use asctime, as it
10207 has undefined behavior for years outside the range -999..9999.
10209 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
10211 Fix race conditions involving setenv, gmtime, localtime, asctime.
10212 Without this fix, interrupts could mess up code that uses these
10213 nonreentrant functions, since setting TZ invalidates existing
10214 tm_zone or tzname values, and since most of these functions return
10215 pointers to static storage.
10216 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
10217 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
10218 Grow the critical sections to include not just invoking
10219 localtime/gmtime, but also accessing these functions' results
10220 including their tm_zone values if any, and any related TZ setting.
10221 (format_time_string): Last arg is now struct tm *, not struct tm **,
10222 so that the struct tm is saved in the critical section.
10223 All callers changed. Simplify allocation of initial buffer, partly
10224 motivated by the fact that memory allocation needs to be outside
10225 the critical section.
10227 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
10229 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
10230 with RESET_INTERVAL.
10232 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
10233 Remove duplicated buffer name initialization.
10235 2012-05-02 Jim Meyering <jim@meyering.net>
10237 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
10239 * xfns.c (x_window): Use xstrdup (Bug#11375).
10241 2012-05-02 Eli Zaretskii <eliz@gnu.org>
10243 * xdisp.c (pos_visible_p): If already at a newline from the
10244 display string before the 'while' loop, don't walk back the glyphs
10245 from it3.glyph_row. Solves assertion violation when the display
10246 string begins with a newline (egg.el). (Bug#11367)
10248 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
10250 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
10253 2012-05-01 Glenn Morris <rgm@gnu.org>
10255 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
10256 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
10257 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
10258 All were removed before 23.1.
10260 * dispnew.c: Remove HAVE_LIBNCURSES test;
10261 it is always true on relevant platforms.
10263 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
10264 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
10266 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
10268 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
10270 * .gdbinit (xpr): Remove checks for no longer existing misc types.
10271 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
10274 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
10276 Do not avoid creating empty evaporating overlays (Bug#9642).
10277 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
10278 That is, do not delete an evaporating overlay if it becomes
10279 empty after its bounds are adjusted to fit within its buffer.
10280 This fix caused other problems, and I'm reverting it until we get
10281 to the bottom of them.
10283 2012-04-27 Chong Yidong <cyd@gnu.org>
10285 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
10287 2012-04-27 Eli Zaretskii <eliz@gnu.org>
10289 * xdisp.c (pos_visible_p): If the window start position is beyond
10290 ZV, start the display from buffer beginning. Prevents assertion
10291 violation in init_iterator when the minibuffer window is scrolled
10292 via the scroll bar.
10294 * window.c (window_scroll_pixel_based): Likewise.
10296 2012-04-27 Chong Yidong <cyd@gnu.org>
10298 * keymap.c (where_is_internal): Doc fix (Bug#10872).
10300 2012-04-27 Glenn Morris <rgm@gnu.org>
10302 * fileio.c (Fcopy_file, Fset_file_selinux_context):
10303 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
10305 2012-04-27 Eli Zaretskii <eliz@gnu.org>
10307 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
10308 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
10310 2012-04-26 Eli Zaretskii <eliz@gnu.org>
10312 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
10313 display element, check also the underlying string or buffer
10314 character. (Bug#11341)
10316 * w32menu.c: Include w32heap.h.
10317 (add_menu_item): If the call to AppendMenuW (via
10318 unicode_append_menu) fails, disable Unicode menus only if we are
10319 running on Windows 9X/Me.
10321 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
10323 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
10324 (xgetint): Add missing shift for LSB tags.
10326 2012-04-24 Martin Rudalics <rudalics@gmx.at>
10328 * keyboard.c (read_char): Don't wipe echo area for select window
10329 events: These might get delayed via `mouse-autoselect-window'
10332 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
10334 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
10335 manipulation of :loaded-from data.
10337 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
10339 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
10340 now a cons (bug#11311).
10342 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
10344 Do not create empty overlays with the evaporate property (Bug#9642).
10345 * buffer.c (Fmove_overlay): Delete an evaporating overlay
10346 if it becomes empty after its bounds are adjusted to fit within
10347 its buffer. Without this fix, in a nonempty buffer (let ((o
10348 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
10349 yields an empty overlay that has the evaporate property, which is
10350 not supposed to happen.
10352 Fix minor GTK3 problems found by static checking.
10353 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

10372 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
10373 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
10374 (__malloc_size_t, __malloc_ptrdiff_t):
10375 Remove. All uses removed, replaced by the definiens if needed,
10376 since we can assume C89 or better now.
10377 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

10467 * sysdep.c [__FreeBSD__]: Minor cleanups.
10468 (list_system_processes, system_process_attributes) [__FreeBSD__]:
10469 Use Emacs indenting style more consistently. Avoid some casts.
10470 Use 'double' consistently rather than mixing 'float' and 'double'.
10472 2012-04-21 Eduard Wiebe <usenet@pusto.de>
10474 * sysdep.c (list_system_processes, system_process_attributes):

10481 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
10483 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
10484 It is never used otherwise.
10486 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
10488 * print.c (print_preprocess): Only check print_depth if print-circle
10490 (print_object): Check for cycles even when print-circle is nil and

10493 2012-04-20 Chong Yidong <cyd@gnu.org>
10495 * process.c (wait_reading_process_output): If EIO occurs on a pty,
10496 set the status to "failed" and ensure that sentinel is run.

10553 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
10554 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
10555 (NEED_MEM_INSERT): New macro.
10556 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
10557 Remove one incorrect comment and fix another.

10562 (r_alloc_size_in_use, r_alloc_freeze, r_alloc_thaw): Remove; unused.
10563 (r_alloc_sbrk): Now static.
10565 Improve ralloc.c interface checking.
10566 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html

10593 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
10594 * s/netbsd.h, s/sol2-6.h:
10595 Remove definition of GC_MARK_STACK, since the default now works.
10596 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
10597 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
10598 no longer the default.
10599 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
10601 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
10603 * lread.c (lisp_file_lexically_bound_p):

10624 2012-04-11 Daniel Colascione <dancol@dancol.org>
10626 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
10627 against is gone. It's better to use vfork now so that when Cygwin
10628 gains a new, working vfork, we use it automatically (bug#10398).
10630 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

10645 (force_quit_count): New var.
10646 (handle_interrupt): Use it.
10648 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
10650 * w32.c (w32_delayed_load): Record the full path of the library
10651 being loaded (bug#10424).
10653 2012-04-09 Glenn Morris <rgm@gnu.org>
10655 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
10656 not just in the obarray, before snarfing them. (Bug#11036)
10658 * Makefile.in ($(leimdir)/leim-list.el):
10659 Pass EMACS rather than BUILT_EMACS.
10661 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
10663 * process.c (make_process):
10664 * process.h: Add integer `gnutls_handshakes_tried' member to
10667 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
10668 Add convenience `GNUTLS_LOG2i' macro.
10670 * gnutls.c (gnutls_log_function2i): Convenience log function.
10671 (emacs_gnutls_read): Use new log functions,
10672 `gnutls_handshakes_tried' process member, and
10673 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
10674 attempts per process (connection).
10676 2012-04-09 Chong Yidong <cyd@gnu.org>
10678 * eval.c (Fuser_variable_p, user_variable_p_eh)

10683 * minibuf.c (Fread_variable): Callers changed.
10685 2012-04-09 Eli Zaretskii <eliz@gnu.org>
10687 * xdisp.c (set_cursor_from_row): If the display string appears in
10688 the buffer at position that is closer to point than the position
10689 after the display string, display the cursor on the first glyph of
10690 the display string. Fixes cursor display when a 'display' text
10691 property immediately follows invisible text. (Bug#11094)
10693 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
10695 composite.c: use 'double' consistently
10696 * composite.c (get_composition_id): Use 'double' consistently
10697 instead of converting 'float' to 'double' and vice versa; this is
10698 easier to understand and avoids a GCC warning.
10700 2012-04-09 Glenn Morris <rgm@gnu.org>
10702 * Makefile.in: Generate leim-list with bootstrap-emacs, in
10703 preparation for dumping it with emacs. (Bug#4789)
10704 (leimdir): New variable.
10705 ($(leimdir)/leim-list.el): New rule.
10706 (emacs$(EXEEXT)): Depend on leim-list.el.
10708 * buffer.c (Qucs_set_table_for_input): Remove. (Bug#9821)
10709 (Fget_buffer_create): Don't call Qucs_set_table_for_input.
10710 (init_buffer_once, syms_of_buffer): Remove Qucs_set_table_for_input.

10724 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
10725 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
10726 (mark_memory): Mark Lisp_Objects only if pointers might hide in
10727 objects, as mark_maybe_pointer will catch them otherwise.
10728 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
10729 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

10733 Fix typo that broke non-Windows builds.
10734 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
10736 2012-04-07 Eli Zaretskii <eliz@gnu.org>
10738 Support building on MS-Windows with libxml2.
10740 * makefile.w32-in (OBJ2): Add xml.$(O).
10741 (GLOBAL_SOURCES): Add xml.c.
10742 ($(BLD)/xml.$(O)): New dependency list.
10744 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
10745 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
10746 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
10747 [!WINDOWSNT]: New macros.
10748 (init_libxml2_functions, libxml2_loaded_p): New functions.
10749 (parse_region): Call fn_xmlCheckVersion instead of using the macro
10750 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
10751 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
10752 Calls xmlCleanupParser only if libxml2 was loaded (or statically
10754 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
10755 Call init_libxml2_functions before calling libxml2 functions.
10756 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
10758 * emacs.c: Don't include libxml/parser.h.
10759 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
10760 xmlCleanupParser directly.
10762 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
10764 2012-04-07 Eli Zaretskii <eliz@gnu.org>
10766 * indent.c (Fvertical_motion): If there is a display string at
10767 point, use it.vpos to compute how many lines to backtrack after
10768 move_it_to point. (Bug#11133)
10770 2012-04-06 Eli Zaretskii <eliz@gnu.org>
10772 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
10773 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
10774 about subtle differences between FETCH_CHAR* and STRING_CHAR*
10775 macros related to unification of CJK characters. For the details,
10776 see the discussion following the message here:
10777 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
10779 2012-04-04 Chong Yidong <cyd@gnu.org>
10781 * keyboard.c (Vdelayed_warnings_list): Doc fix.
10783 2012-04-01 Eli Zaretskii <eliz@gnu.org>
10785 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
10786 instead of alloca. (Bug#11138)
10788 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
10790 * w32menu.c (is_simple_dialog): Properly check lisp types.
10793 2012-03-31 Eli Zaretskii <eliz@gnu.org>
10795 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
10796 position we get to after a call to move_it_to fails the
10797 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
10798 only if we wind up in a string from display property. (Bug#11063)
10800 * window.c (Fdelete_other_windows_internal): Invalidate the row
10801 and column information about mouse highlight, so that redisplay
10802 restores it after reallocating the glyph matrices. (Bug#7464)
10804 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
10805 string comes from a `display' text property, use the buffer
10806 position of that property as if we actually saw that position in
10808 (move_it_by_lines): Remove the assertion that
10809 "it->current_x == 0 && it->hpos == 0" which can be legitimately
10810 violated when there's a before-string at the beginning of a line.
10813 2012-03-30 Eli Zaretskii <eliz@gnu.org>
10815 * xdisp.c (append_space_for_newline): If the default face was
10816 remapped, use the remapped face for the appended newline.
10817 (extend_face_to_end_of_line): Use the remapped default face for
10818 extending the face to the end of the line.
10819 (display_line): Call extend_face_to_end_of_line when the default
10820 face was remapped. (Bug#11068)
10822 2012-03-29 Eli Zaretskii <eliz@gnu.org>
10824 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
10826 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
10828 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
10830 2012-03-27 Glenn Morris <rgm@gnu.org>
10832 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
10835 2012-03-26 Kenichi Handa <handa@m17n.org>
10837 * dispextern.h (struct glyph): Fix previous change. Change the
10838 bit length of glyphless.ch to 25 (Bug#11082).
10840 2012-03-26 Chong Yidong <cyd@gnu.org>
10842 * keyboard.c (Vselection_inhibit_update_commands): New variable.
10843 (command_loop_1): Use it; inhibit selection update for
10844 handle-select-window too (Bug#8996).
10846 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
10848 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
10850 2012-03-25 Kenichi Handa <handa@m17n.org>
10852 * dispextern.h (struct glyph): Change the bit length of
10853 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
10855 2012-03-24 Eli Zaretskii <eliz@gnu.org>
10857 * s/ms-w32.h (tzname): Include time.h before redirecting to
10858 _tzname. Fixes the MSVC build. (Bug#9960)
10860 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
10862 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
10865 * xterm.c (XTread_socket): Only modify handling_signal if
10866 !SYNC_INPUT. (Bug#11080)
10868 2012-03-23 Eli Zaretskii <eliz@gnu.org>
10870 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
10871 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
10872 when fetching a multibyte character consumes more bytes than
10873 CHAR_BYTES returns, due to unification of CJK characters in
10874 string_char. (Bug#11073)
10876 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
10878 * process.c (wait_reading_process_output): Handle pty disconnect
10879 by refraining from sending oneself a SIGCHLD (bug#10933).
10881 2012-03-22 Chong Yidong <cyd@gnu.org>

10886 Mark string as coming from a prefix property.
10887 (handle_face_prop): Use default face for prefix strings (Bug#4281).
10888 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
10890 2012-03-21 Chong Yidong <cyd@gnu.org>
10892 * xfaces.c (Vface_remapping_alist): Doc fix.
10894 2012-03-20 Eli Zaretskii <eliz@gnu.org>
10896 * w32proc.c (Fw32_set_console_codepage)
10897 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
10900 2012-03-20 Chong Yidong <cyd@gnu.org>
10902 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
10903 to reflect default non-nil value of redisplay-dont-pause.
10905 2012-03-19 Kenichi Handa <handa@m17n.org>
10907 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
10908 it fit in a valid range (Bug#11003).
10910 2012-03-18 Eli Zaretskii <eliz@gnu.org>
10912 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
10913 that is not from display property, accept the row as a "cursor
10914 row" if one of the string's character has a non-nil `cursor'
10915 property. Fixes cursor positioning when there are newlines in
10916 overlay strings, e.g. in icomplete.el. (Bug#11035)
10918 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
10920 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
10922 2012-03-12 Chong Yidong <cyd@gnu.org>
10924 * eval.c (inhibit_lisp_code): Rename from
10925 inhibit_window_configuration_change_hook; move from window.c.
10927 * xfns.c (unwind_create_frame_1, Fx_create_frame):
10928 * window.c (run_window_configuration_change_hook)
10929 (syms_of_window): Callers changed.
10931 2012-03-11 Chong Yidong <cyd@gnu.org>
10933 * keymap.c (Fkey_description): Doc fix (Bug#9700).
10935 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
10937 2012-03-10 Chong Yidong <cyd@gnu.org>
10939 * frame.c (other_visible_frames): Don't assume the selected frame
10940 is visible (Bug#10955).
10942 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
10944 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
10946 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
10948 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
10949 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
10952 2012-03-03 Glenn Morris <rgm@gnu.org>
10954 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
10956 2012-03-02 Eli Zaretskii <eliz@gnu.org>
10958 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
10959 position past the first glyph_row that ends at ZV. (Bug#10902)
10960 (redisplay_window, next_element_from_string): Fix typos in
10962 (redisplay_window): Pass to move_it_vertically the margin in
10963 pixels, not in screen lines.
10965 2012-03-02 Glenn Morris <rgm@gnu.org>
10967 * buffer.c (buffer-list-update-hook): Doc fix.
10969 2012-02-29 Eli Zaretskii <eliz@gnu.org>
10971 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
10972 push_it before setting up the iterator for the first overlay
10973 string, even if we have an empty string loaded.
10974 (next_overlay_string): If there's an empty string on the iterator
10975 stack, pop the stack. (Bug#10903)
10977 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
10979 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
10980 Suggested by Stefan Monnier in
10981 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
10982 * alloc.c (widen_to_Lisp_Object): New static function.
10983 (mark_memory): Also mark Lisp_Objects by fetching pointer words
10984 and widening them to Lisp_Objects. This would work even if
10985 USE_LSB_TAG is defined and wide integers are used, which might
10986 happen in a future version of Emacs.
10988 2012-02-25 Chong Yidong <cyd@gnu.org>
10990 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
10993 * xselect.c (Fx_selection_exists_p): Doc fix.
10994 (x_clipboard_manager_save_all): Print an informative message
10995 before saving to clipboard manager.
10997 2012-02-24 Chong Yidong <cyd@gnu.org>
10999 * keyboard.c (process_special_events): Handle all X selection
11000 requests in kbd_buffer, not just the next one (Bug#8869).
11002 2012-02-23 Chong Yidong <cyd@gnu.org>
11004 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
11005 call when setting menu-bar-lines and tool-bar-lines parameters.
11006 (unwind_create_frame_1): New helper function.
11008 * window.c (inhibit_window_configuration_change_hook): New var.
11009 (run_window_configuration_change_hook): Obey it.
11010 (syms_of_window): Initialize it.
11012 2012-02-22 Chong Yidong <cyd@gnu.org>

11019 * fileio.c (Vfile_name_handler_alist): Doc fix.
11021 * buffer.c (Fget_file_buffer): Protect against invalid file
11022 handler return value.

11027 when computing $valmask.
11029 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
11030 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
11031 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
11032 It's useless in that case, and it can cause problems on hosts
11033 that allocate halves of EMACS_INT values separately.
11034 Reported by Dan Horák. Diagnosed by Andreas Schwab in
11035 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
11036 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
11037 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
11038 it avoids undefined behavior on hosts where shifting right by more
11039 than the word width has undefined behavior.
11041 2012-02-19 Chong Yidong <cyd@gnu.org>
11043 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
11044 (Funhandled_file_name_directory, Ffile_name_as_directory)
11045 (Fdirectory_file_name, Fexpand_file_name)
11046 (Fsubstitute_in_file_name): Protect against invalid file handler
11047 return values (Bug#10845).
11049 2012-02-18 Eli Zaretskii <eliz@gnu.org>
11051 * .gdbinit (pitx): Fix incorrect references to fields of the
11054 2012-02-17 Chong Yidong <cyd@gnu.org>

11058 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
11060 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
11061 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
11063 2012-02-15 Chong Yidong <cyd@gnu.org>
11065 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
11066 marked as special. Also, starting docstrings with * is obsolete.
11068 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
11070 * gnutls.c (emacs_gnutls_write): Fix last change.

11079 * keymap.c (Fsingle_key_description): Handle char ranges.
11081 2012-02-12 Chong Yidong <cyd@gnu.org>
11083 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
11084 as that creates a dangerous corner case.
11086 * window.c (Fdelete_window_internal): Invalidate the mouse
11087 highlight (Bug#9904).
11089 2012-02-12 Glenn Morris <rgm@gnu.org>
11091 * xselect.c (Fx_own_selection_internal)
11092 (Fx_get_selection_internal, Fx_disown_selection_internal)
11093 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
11094 * nsselect.m (Fx_own_selection_internal)
11095 (Fx_disown_selection_internal, Fx_selection_exists_p)
11096 (Fx_selection_owner_p, Fx_get_selection_internal):
11097 Sync docs and argument specs with the xselect.c versions.
11099 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
11101 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
11103 2012-02-11 Eli Zaretskii <eliz@gnu.org>
11105 * w32select.c (Fx_selection_exists_p): Sync doc string and
11106 argument list with xselect.c. (Bug#10783)
11108 * w16select.c (Fx_selection_exists_p): Sync doc string and
11109 argument list with xselect.c. (Bug#10783)

11656 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
11657 verifies glyph row's hash code--we have just reallocated the
11658 glyphs, so their contents can be complete garbage. (Bug#10164)

11822 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
11823 is set, removing the need for VIRT_ADDRESS_VARIES.
11824 (PURE_P): Use a more-efficient implementation that needs just one
11825 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
11826 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
11827 to 4 (xorl, subq, cmpq, setbe).
11828 * alloc.c (pure): Always extern now, since that's the

11831 consistency with the new puresize.h.
11832 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
11833 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

11839 (erase_phys_cursor, update_window_cursor, show_mouse_face)
11840 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
11841 behave as if the cursor position were at the window margin.
11843 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
11844 and the cursor position is out of bounds, behave as if the cursor
11845 position were at the window margin. (Bug#10075)
11847 2011-11-18 Chong Yidong <cyd@gnu.org>
11849 * window.c (Fwindow_combination_limit): Make first argument

11868 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
11870 * xdisp.c (row_hash): New function, body extracted from
11871 compute_line_metrics.
11872 (compute_line_metrics): Call row_hash, instead of computing the
11875 * dispnew.c (verify_row_hash): Call row_hash for computing the
11876 hash code of a row, instead of duplicating code from xdisp.c.
11878 * dispextern.h (row_hash): Add prototype.
11880 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
11882 * frame.c (delete_frame): Don't delete the terminal when the last

11918 * xdisp.c (display_line): Move the call to
11919 highlight_trailing_whitespace before the call to
11920 compute_line_metrics, since the latter needs to see the final
11921 faces of all the glyphs to compute ROW's hash value.

11931 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
11932 with user-defined heap size. Bump the default size of the temacs

11936 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
11937 current_matrix and desired_matrix. (Bug#9990)
11938 (verify_row_hash) [XASSERTS]: New function.

11985 Avoid some portability problems by eschewing 'extern inline' functions.
11986 The trivial performance wins aren't worth the portability hassles; see
11987 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
11989 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

12059 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
12061 Fix some portability problems with 'inline'.
12062 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
12063 (window_box_width, window_box_left, window_box_left_offset)
12064 (window_box_right, window_box_right_offset): Declare extern.
12065 Otherwise, these inline functions do not conform to C99 and
12066 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
12067 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
12068 * intervals.c (adjust_intervals_for_insertion)
12069 (adjust_intervals_for_deletion): Now extern, because otherwise the
12070 extern inline functions 'offset_intervals' couldn't refer to it.
12071 (static_offset_intervals): Remove.
12072 (offset_intervals): Rewrite using the old contents of
12073 static_offset_intervals. The old version didn't conform to C99
12074 because an extern inline function contained a reference to an
12075 identifier with static linkage.
12077 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
12079 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

12085 iterator's bidi_p flag if Vpurify_flag is non-nil. (Bug#9963)
12086 (Fcurrent_bidi_paragraph_direction): If Vpurify_flag is non-nil,
12087 return Qleft_to_right.

12096 (Fwindow_margins, Fwindow_fringes, Fwindow_scroll_bars)
12097 (Fwindow_vscroll): Doc fix.
12098 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
12099 argument, since it makes no sense to pass a live window and for
12100 consistency with window-child.

12128 (unwind_create_frame): New function (Bug#9943).
12129 (Fx_create_frame): Restructure code to be more similar to the one in
12130 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
12131 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
12132 Move terminal->reference_count++ just before making the frame official

12141 official. Move initialization of image_cache_refcount and
12142 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

12181 * xdisp.c (note_mouse_highlight): If either of
12182 previous/next-single-property-change returns nil, treat that as
12183 the beginning or the end of the buffer. (Bug#9955)
12185 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
12187 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or

12210 (mouse_face_from_buffer_pos, note_mouse_highlight):
12211 Rename cover_string to disp_string.
12213 2011-11-01 Martin Rudalics <rudalics@gmx.at>

12216 Vtemp_buffer_show_specifiers.
12217 (Vtemp_buffer_show_specifiers): Remove unused variable.
12219 2011-10-30 Eli Zaretskii <eliz@gnu.org>
12221 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
12222 past the beginning of the current glyph matrix.
12224 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
12226 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.

12270 2011-10-29 Glenn Morris <rgm@gnu.org>
12272 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
12273 Not clear what it was for, and it causes various bugs. (Bug#9839)
12275 2011-10-28 Eli Zaretskii <eliz@gnu.org>
12277 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a

12297 2011-10-28 Eli Zaretskii <eliz@gnu.org>
12299 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem

12310 (w32font_open_internal, compute_metrics):
12311 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
12312 instead of calling the "wide" APIs directly.
12314 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
12316 * w32.h (syms_of_w32font): Add prototype.

12322 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
12323 (Fmove_to_window_line): Doc fix.
12325 2011-10-27 Chong Yidong <cyd@gnu.org>
12327 * process.c (make_process): Set gnutls_state to NULL.
12329 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
12330 non-NULL, regardless of GNUTLS_INITSTAGE.
12331 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal

12379 (bidi_resolve_weak): Don't enter the expensive loop if the current
12380 position is before next_en_pos. Record the bidi type of the first
12381 non-ET, non-BN character we find, in addition to its position.
12382 (bidi_level_of_next_char): Invalidate next_en_type when
12383 next_en_pos is over-stepped.
12385 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
12387 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
12388 * editfns.c: Rewrite current-time-zone so that it invokes
12389 the equivalent of (format-time-string "%Z") to get the time zone name.
12390 This fixes a bug when the time zone name contains characters that
12391 need converting from the system time locale to Emacs internal format.
12392 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
12393 that patch fixed format-time-string to do the conversion, but
12394 I forgot to fix current-time-zone.
12395 (format_time_string): New function, containing most of
12396 what Fformat_time_string used to contain.
12397 (Fformat_time_string): Rewrite in terms of format_time_string.
12398 This doesn't change this function's behavior.
12399 (current-time-zone): Rewrite to use format_time_string.
12400 This fixes the bug reported by Michael Schierl in
12401 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
12402 Jason Rumney's 2007-06-07 change worked around this bug, but
12404 * systime.h (tzname, timezone): Remove no-longer-used declarations.
12406 2011-10-19 Eli Zaretskii <eliz@gnu.org>
12408 * xdisp.c (start_display): If the character at POS is displayed
12409 via a display vector, reset IT->current.dpvec_index to zero.
12410 (try_window_reusing_current_matrix): If a line ends in a display
12411 vector or the next line starts in a display vector, continue
12412 redrawing the window even though the character position of
12413 start_row was reached.
12416 2011-10-18 Chong Yidong <cyd@gnu.org>
12418 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
12419 with nobreak-char-display too.
12421 2011-10-18 Eli Zaretskii <eliz@gnu.org>
12423 Fix part 3 of bug#9771.
12424 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
12425 (bidi_resolve_neutral): Don't enter the expensive loop looking for
12426 non-neutral characters if the current character is a paragraph
12427 separator (a.k.a. Newline). This avoids running the same
12428 expensive loop twice, once when we consume the preceding newline
12429 and the other time when the line actually needs to be displayed.
12430 Avoid the loop when we see neutrals on the base embedding level
12431 following a character whose directionality is the same as the
12432 paragraph's. This avoids running the expensive loop when a line
12433 ends in a long sequence of neutrals, like control characters.
12434 Add assertion against STRONG_AL type. Slightly rearrange code
12435 that determines the type of a neutral given the first non-neutral
12437 (bidi_level_of_next_char): Set next_en_pos to zero when
12438 invalidating its info.
12440 2011-10-17 Eli Zaretskii <eliz@gnu.org>
12442 * xdisp.c (push_display_prop): Determine whether to record string
12443 or buffer position by IT->string, not by IT->method. Allow
12444 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
12445 (move_it_vertically_backward): Don't look for character position
12446 immediately after the newline when in a continuation line.
12449 2011-10-15 Martin Rudalics <rudalics@gmx.at>
12451 * window.c (coordinates_in_window): Rewrite and delabelize
12452 vertical border check. (Bug#5357) (Bug#9618)
12454 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
12456 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
12457 errors in XSetWindowBorder (bug#9310).
12459 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
12461 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
12462 avoid crash when xmalloc overrun checking is enabled.
12464 2011-10-13 Eli Zaretskii <eliz@gnu.org>
12466 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
12467 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
12468 cursor motion with <left> and <right> arrow keys.
12470 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
12471 some callers set that themselves.
12473 2011-10-12 Eli Zaretskii <eliz@gnu.org>
12475 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
12476 display string and the previous row comes from the same string and
12477 is empty. (Bug#9739) (Bug#9738)
12479 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
12481 * doc.c (get_doc_string): Encode file name (bug#9735).
12483 2011-10-12 Eli Zaretskii <eliz@gnu.org>
12485 * bidi.c (bidi_level_of_next_char):
12486 * xdisp.c (get_visually_first_element): Remove old incorrect
12487 comments regarding the Unicode Line Separator character.
12489 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
12491 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>

12494 boundary if nzombies > MAX_ZOMBIES.
12495 * alloc.c (dump_zombies): Add missing format specifier.
12497 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
12499 * xdisp.c (set_cursor_from_row): Simplify conditionals,
12500 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
12502 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
12503 Some packages use them to denote characters with modifiers.
12505 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
12507 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
12508 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
12509 matching a pp-number. Rename parameter var to var1.
12511 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
12513 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
12515 2011-10-08 Glenn Morris <rgm@gnu.org>
12517 * callint.c (Fcall_interactively): Give a more explicit error for the
12518 'c' case with a non-character input. (Bug#8479)
12520 2011-10-08 Eli Zaretskii <eliz@gnu.org>
12522 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
12524 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
12525 lines that are hscrolled on the left.
12527 * dispnew.c (buffer_posn_from_coords): Account for a possible
12528 presence of header-line. (Bug#4426)
12530 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
12532 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
12533 Don't advertise functionality which we discourage or doesn't work.
12535 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
12537 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
12538 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
12539 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
12540 this makes Emacs dump core during garbage collection on rare
12541 occasions. sizeof is obviously inferior to offsetof here, so
12542 stick with offsetof.
12543 (GC_POINTER_ALIGNMENT): New macro.
12544 (mark_memory): Omit 3rd (offset) arg; caller changed.
12545 Don't assume EMACS_INT alignment is the same as pointer alignment.
12547 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
12549 * keyboard.c (read_key_sequence_remapped): New var.
12550 (read_key_sequence): Compute remapping in the right buffer.
12551 (command_loop_1): Use read_key_sequence's remapping directly.
12553 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
12555 * dired.c (file_name_completion): Don't expand file name.
12556 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
12557 before checking file name handler.
12559 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
12560 they've been requested explicitly (bug#9591).
12562 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
12564 * keymap.c (Fsingle_key_description): Use make_specified_string
12565 instead of build_string to build string from push_key_description.
12568 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
12570 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
12571 This fixes a Y2038 bug on 64-bit hosts.
12572 * buffer.c (reset_buffer):
12573 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
12574 (Fclear_buffer_auto_save_failure):
12575 Use 0, not -1, to represent an unset failure time, since time_t
12576 might not be signed.
12578 Remove dependency on glibc malloc internals.
12579 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12580 Move back here from lisp.h, but with their new implementations.
12581 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
12582 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
12583 * charset.c (charset_table_init): New static var.
12584 (syms_of_charset): Use it instead of xmalloc. This removes a
12585 dependency on glibc malloc internals. See Eli Zaretskii's comment in
12586 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
12587 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12588 Move back to alloc.c.
12589 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
12590 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
12592 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
12594 * nsterm.m (windowDidResize): Call x_set_window_size only when
12595 ns_in_resize is true. Otherwise set pixelwidth/height and
12596 call change_frame_size (Bug#9628).
12598 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
12600 Port --enable-checking=all to Fedora 14 x86-64.
12601 * charset.c (syms_of_charset): Also account for glibc malloc's
12602 internal overhead when calculating the initial malloc maximum.
12604 Port --enable-checking=all to Fedora 14 x86.
12605 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12607 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
12608 (overrun_check_realloc, overrun_check_free):
12609 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
12610 That way, xmalloc returns a properly-aligned pointer even if
12611 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
12612 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
12613 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
12614 into account when calculating the initial malloc maximum.
12615 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12616 Move here from alloc.c, so that charset.c can use it too.
12617 Properly align; the old code wasn't right for common 32-bit hosts
12618 when configured with --enable-checking=all.
12619 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
12620 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
12622 2011-09-29 Eli Zaretskii <eliz@gnu.org>
12624 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
12627 2011-09-28 Eli Zaretskii <eliz@gnu.org>
12629 * xdisp.c (compute_display_string_end): If there's no display
12630 string at CHARPOS, return -1.
12632 * bidi.c (bidi_fetch_char): When compute_display_string_end
12633 returns a negative value, treat the character as a normal
12634 character not covered by a display string. (Bug#9624)
12636 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
12638 * lread.c (Fread_from_string): Fix typo in docstring.
12640 2011-09-27 Eli Zaretskii <eliz@gnu.org>
12642 * xdisp.c (handle_invisible_prop): If invisible text ends on a
12643 newline, reseat the iterator instead of bidi-iterating there one
12644 character at a time. (Bug#9610)
12645 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
12646 TO_CHARPOS if the bidi iterator is at base embedding level.
12648 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
12650 * lread.c (readevalloop): Use correct code for NBSP.
12651 (read1): Likewise. (Bug#9608)
12653 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
12655 * dbusbind.c (Fdbus_register_signal): When service is not
12656 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
12658 2011-09-25 Glenn Morris <rgm@gnu.org>
12660 * buffer.c (truncate-lines): Doc fix.
12662 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
12664 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
12665 (Fset_window_next_buffers): Doc fix.
12667 2011-09-24 Glenn Morris <rgm@gnu.org>
12669 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
12671 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
12673 Fix minor problems found by static checking.
12674 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
12675 * indent.c (Fvertical_motion): Fix == vs = typo.
12677 2011-09-24 Eli Zaretskii <eliz@gnu.org>
12679 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
12680 Default value is now t. Doc fix.
12682 * indent.c (Fvertical_motion): Compute and apply the overshoot
12683 logic when moving up, not only when moving down. Fix the
12684 confusing name and values of the it_overshoot_expected variable;
12685 logic changes accordingly. (Bug#9254) (Bug#9549)
12687 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
12688 CHARPOS is covered by a display string which includes newlines.
12689 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
12690 is covered by a display string with embedded newlines.
12692 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
12694 * dbusbind.c (Fdbus_register_signal): Add match rule to
12695 Vdbus_registered_objects_table. (Bug#9581)
12696 (Fdbus_register_method, Vdbus_registered_objects_table):
12699 2011-09-24 Jim Meyering <meyering@redhat.com>
12701 do not ignore write error for any output size
12702 The previous change was incomplete.
12703 While it makes emacs --batch detect the vast majority of stdout
12704 write failures, errors were still ignored whenever the output size is
12705 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
12706 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
12707 && echo FAIL: ignored write error
12708 FAIL: ignored write error
12709 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
12710 && echo FAIL: ignored write error
12711 FAIL: ignored write error
12712 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
12714 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
12716 * emacs.c (Fkill_emacs): In noninteractive mode exit
12717 non-successfully if a write error occurred on stdout. (Bug#9574)
12719 2011-09-21 Eli Zaretskii <eliz@gnu.org>
12721 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
12724 * dispextern.h (struct it): Update the comment documenting what
12727 2011-09-20 Eli Zaretskii <eliz@gnu.org>
12729 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
12730 a display string, extend search for cursor position to end of row.
12731 (find_row_edges): If the row ends in a newline from a display
12732 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
12733 Handle the case of a display string with multiple newlines.
12734 (Fcurrent_bidi_paragraph_direction): Fix search for previous
12735 non-empty line. Fixes confusing cursor motion with arrow keys at
12736 the beginning of a line that starts with whitespace.
12738 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
12740 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
12743 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
12745 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
12746 boolean (Bug#9154).
12748 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12750 * xdisp.c (display_line): Record maximum and minimum buffer
12751 positions even if no glyphs were produced (e.g., by a zero-width
12752 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
12753 buffer positions that will be removed from the glyph row because
12755 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
12756 column is beyond frame width: don't subtract 1 "pixel" when
12757 computing width of the stretch.
12758 (reseat_at_next_visible_line_start): Undo the change made on
12759 2011-09-17 that saved paragraph information and restored it after
12760 the call to `reseat'. (Bug#9545)
12762 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12764 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
12765 and turn window cursor on if cleared (Bug#9415).
12767 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
12769 * search.c (boyer_moore): Take unibyte characters from pattern
12770 literally. (Bug#9458)
12772 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12774 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
12776 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
12778 Fix minor problem found by static checking.
12779 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
12780 initialized, to pacify gcc -Wuninitialized.
12782 * fileio.c: Report proper errno when syscall falls.
12783 (Finsert_file_contents): Save and restore errno,
12784 so that report_file_error outputs the correct diagnostic.
12785 (Fwrite_region) [CLASH_DETECTION]: Likewise.
12787 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12789 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
12791 2011-09-17 Eli Zaretskii <eliz@gnu.org>
12793 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
12794 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
12796 2011-09-17 Eli Zaretskii <eliz@gnu.org>
12798 * xdisp.c (reseat_at_next_visible_line_start): Keep information
12799 about the current paragraph and restore it after the call to reseat.
12801 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
12802 (bidi_find_paragraph_start): Search back for paragraph beginning
12803 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
12804 (bidi_move_to_visually_next): Only trigger paragraph-related
12805 computations when the last character is a newline or at EOB, not
12806 just any NEUTRAL_B. (Bug#9470)
12808 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
12809 truncated lines if point is covered by a display string. (Bug#9524)
12811 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
12813 * xselect.c: Relax test for outgoing X longs (Bug#9498).
12814 (cons_to_x_long): New function.
12815 (lisp_data_to_selection_data): Use it. Correct the test for
12816 short-versus-long data; it was negated. Break out of vector
12817 loop, for efficiency, when a long datum is discovered.
12819 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
12821 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
12823 2011-09-16 Eli Zaretskii <eliz@gnu.org>
12825 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
12826 GCC PR/17406) by declaring this function with external scope.
12828 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
12830 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
12831 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
12833 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
12835 * editfns.c (Fformat): Correctly handle text properties on "%%".
12837 2011-09-15 Eli Zaretskii <eliz@gnu.org>
12839 * xterm.c (x_draw_composite_glyph_string_foreground):

12841 * term.c (encode_terminal_code):
12842 * composite.c (composition_update_it, get_composition_id):
12843 * xdisp.c (get_next_display_element)
12844 (fill_composite_glyph_string): Add comments about special meaning
12845 of TAB characters in a composition.
12847 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
12849 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
12850 This occurs when processing a multibyte format.
12851 Problem reported by Wolfgang Jenker.
12853 2011-09-15 Johan Bockgård <bojohan@gnu.org>
12855 * xdisp.c (try_cursor_movement): Only check for exact match if
12856 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
12858 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
12860 Remove unused external symbols.
12861 * dispextern.h (calc_pixel_width_or_height): Remove decl.
12862 * xdisp.c (calc_pixel_width_or_height): Now static.
12863 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
12864 * indent.c (check_display_width):
12865 * w32term.c: Fix comment to match code.
12866 * xterm.c, xterm.h (x_catching_errors): Remove.
12868 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
12870 * xselect.c: Use signed conversions more consistently (Bug#9498).
12871 (selection_data_to_lisp_data): Assume incoming selection data are
12872 signed integers, not unsigned. This is to be consistent with
12873 outgoing selection data, which was modified to use signed integers
12874 in as part of the fix to Bug#9196 in response to Jan D.'s comment
12875 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
12876 expects long, not unsigned long.
12878 2011-09-14 Eli Zaretskii <eliz@gnu.org>
12880 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
12881 computation of loop end. Reported by Johan Bockgård
12884 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
12886 * frame.c (Fother_visible_frames_p): Function deleted.
12888 2011-09-12 Eli Zaretskii <eliz@gnu.org>
12890 * indent.c (compute_motion): Process display vector front to back
12891 rather than the other way around. (Bug#2496)
12893 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
12895 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
12897 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
12899 * minibuf.c (Fread_from_minibuffer): Doc fix.
12901 2011-09-11 Eli Zaretskii <eliz@gnu.org>
12903 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
12904 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
12906 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
12908 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
12909 value for non-existent files.
12911 2011-09-11 Eli Zaretskii <eliz@gnu.org>
12913 * fileio.c (Finsert_file_contents): If the file cannot be opened,
12914 set its "size" to -1. This will set the modtime_size field of
12915 the corresponding buffer to -1, which is what
12916 verify-visited-file-modtime expects for files that do not exist.
12919 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
12921 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
12923 * lisp.h: ... from here. push_key_description is no longer
12924 defined in keyboard.c, so its declaration should not be in
12925 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
12926 logically belongs with push_key_description.
12928 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
12930 * buffer.h: Include <sys/types.h> instead of <time.h>.
12931 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
12932 Problem reported by Herbert J. Skuhra.
12934 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
12936 * xml.c (parse_region): Make the parsing work for
12937 non-comment-starting XML files again (bug#9144).
12939 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
12941 * image.c (gif_load): Fix calculation of bottom and right corner.
12944 2011-09-10 Eli Zaretskii <eliz@gnu.org>
12946 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
12947 redisplay in small windows.
12949 2011-09-09 Eli Zaretskii <eliz@gnu.org>
12951 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
12953 2011-09-08 Martin Rudalics <rudalics@gmx.at>
12955 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
12956 Operate on live windows only.
12958 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
12960 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
12962 2011-09-07 Eli Zaretskii <eliz@gnu.org>
12964 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
12965 only under bidi iteration.
12967 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
12969 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
12971 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12973 isnan: Fix porting problem to Solaris 10 with bundled gcc.
12974 Without this fix, the command to link temacs failed due to an
12975 undefined symbol __builtin_isnan. This is because
12976 /usr/include/iso/math_c99.h #defines isnan(x) to
12977 __builtin_isnan(x), but the bundled gcc, which identifies itself
12978 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
12980 * floatfns.c (isnan): #undef, and then #define to a clone of
12982 (Fisnan): Always define, since it's always available now.
12983 (syms_of_floatfns): Always define isnan at the Lisp level.
12985 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12987 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
12989 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12991 * fileio.c: Fix bugs with large file offsets (Bug#9428).
12992 The previous code assumed that file offsets (off_t values) fit in
12993 EMACS_INT variables, which is not true on typical 32-bit hosts.
12994 The code messed up by falsely reporting buffer overflow in cases
12995 such as (insert-file-contents "big" nil 1 2) into an empty buffer
12996 when "big" contains more than 2**29 bytes, even though this
12997 inserts just one byte and does not overflow the buffer.
12998 (Finsert_file_contents): Store file offsets as off_t
12999 values, not as EMACS_INT values. Check for overflow when
13000 converting between EMACS_INT and off_t. When checking for
13001 buffer overflow or for overlap, take the offsets into account.
13002 Don't use EMACS_INT for small values where int suffices.
13003 When checking for overlap, fix a typo: ZV was used where
13004 ZV_BYTE was intended.
13005 (Fwrite_region): Don't assume off_t fits into 'long'.
13006 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
13008 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
13010 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
13012 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13014 sprintf-related integer and memory overflow issues (Bug#9412).
13016 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
13017 (esprintf, exprintf, evxprintf): New functions.
13018 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
13019 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
13020 (modify_event_symbol): Do not assume that the length of
13021 name_alist_or_stem is safe to alloca and fits in int.
13022 (Fexecute_extended_command): Likewise for function name and binding.
13023 (Frecursion_depth): Wrap around reliably on integer overflow.
13024 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
13025 since some callers pass EMACS_INT values.
13026 (Fsingle_key_description): Don't crash if symbol name contains more
13027 than MAX_ALLOCA bytes.
13028 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
13029 (get_minibuffer): Arg is now EMACS_INT, not int.
13030 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
13031 (esprintf, exprintf, evxprintf): New decls.
13032 * window.h (command_loop_level, minibuf_level): Reflect API changes.
13034 * dbusbind.c (signature_cat): New function.
13035 (xd_signature, Fdbus_register_signal):
13036 Do not overrun buffer; instead, report string overflow.
13038 * dispnew.c (add_window_display_history): Don't overrun buffer.
13039 Truncate instead; this is OK since it's just a log.
13041 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
13042 even if the time zone offset is outlandishly large.
13043 Don't mishandle offset == INT_MIN.
13045 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
13046 when creating daemon; the previous buffer-overflow check was incorrect.
13048 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
13049 which has the guts of the old verror function.
13051 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
13052 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
13054 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
13055 (font_unparse_xlfd): Don't blindly alloca long strings.
13056 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
13057 fits in int, when using sprintf. Use single snprintf to count
13058 length of string rather than counting it via multiple sprintfs;
13059 that's simpler and more reliable.
13060 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
13061 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
13062 sprintf, in case result does not fit in int.
13064 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
13065 (fontset_from_font): Print it.
13067 * frame.c (tty_frame_count): Now printmax_t, not int.
13068 (make_terminal_frame, set_term_frame_name): Print it.
13069 (x_report_frame_params): In X, window IDs are unsigned long,
13070 not signed long, so print them as unsigned.
13071 (validate_x_resource_name): Check for implausibly long names,
13072 and don't assume name length fits in 'int'.
13073 (x_get_resource_string): Don't blindly alloca invocation name;
13074 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
13077 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
13078 (xg_check_special_colors, xg_set_geometry):
13079 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
13081 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
13082 Use esprintf, not sprintf, in case result does not fit in int.
13084 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13085 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
13086 it as a large positive number.
13087 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
13088 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13090 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
13091 in case result does not fit in int.
13093 * print.c (float_to_string): Detect width overflow more reliably.
13094 (print_object): Make sprintf buffer a bit bigger, to avoid potential
13095 buffer overrun. Don't assume list length fits in 'int'. Treat
13096 print length of 0 as 0, not as infinity; to be consistent with other
13097 uses of print length in this function. Don't overflow print length
13098 index. Don't assume hash table size fits in 'long', or that
13099 vectorlike size fits in 'unsigned long'.
13101 * process.c (make_process): Use printmax_t, not int, to format
13102 process-name gensyms.
13104 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
13106 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
13107 to avoid potential buffer overrun.
13109 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
13110 if X resource line is longer than 512 bytes.
13112 * xfns.c (x_window): Make sprintf buffer a bit bigger
13113 to avoid potential buffer overrun.
13115 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
13117 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
13119 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13121 Integer overflow fixes for scrolling, etc.
13122 Without these, Emacs silently mishandles large integers sometimes.
13123 For example, "C-u 4294967297 M-x recenter" was treated as if
13124 it were "C-u 1 M-x recenter" on a typical 64-bit host.
13126 * xdisp.c (try_window_id): Check Emacs fixnum range before
13127 converting to 'int'.
13129 * window.c (window_scroll_line_based, Frecenter):
13130 Check that an Emacs fixnum is in range before assigning it to 'int'.
13131 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
13132 values converted from Emacs fixnums.
13133 (Frecenter): Don't wrap around a line count if it is out of 'int'
13134 range; instead, treat it as an extreme value.
13135 (Fset_window_configuration, compare_window_configurations):
13136 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
13138 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
13139 that can exceed INT_MAX. Check that EMACS_INT value is in range
13140 before assigning it to the (possibly-narrower) index.
13141 (match_limit): Don't assume that a fixnum can fit in 'int'.
13143 * print.c (print_object): Use ptrdiff_t, not int, for index that can
13146 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
13147 (Fvertical_motion): Don't wrap around LINES values that don't fit
13148 in 'int'. Instead, treat them as extreme values. This is good
13149 enough for windows, which can't have more than INT_MAX lines anyway.
13151 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
13153 * Require libxml/parser.h to avoid compilation warning.
13155 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
13157 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
13158 since this reportedly can destroy thread storage.
13160 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
13162 * syntax.c (find_defun_start): Update all cache variables if
13163 exiting early (Bug#9401).
13165 2011-08-30 Eli Zaretskii <eliz@gnu.org>
13167 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
13169 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
13170 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
13171 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
13173 * term.c (tty_append_glyph): New function.
13174 (produce_stretch_glyph): Static function and its prototype deleted.
13176 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
13179 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
13181 * image.c (parse_image_spec): Check for nonnegative, not for positive,
13182 when checking :margin (Bug#9390).
13183 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
13184 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
13185 so that the name doesn't mislead. All uses changed.
13187 2011-08-28 Johan Bockgård <bojohan@gnu.org>
13189 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
13192 2011-08-27 Eli Zaretskii <eliz@gnu.org>
13194 * xdisp.c (move_it_to): Don't bail out early when reaching
13195 position beyond to_charpos, if we are scanning backwards.
13196 (move_it_vertically_backward): When DY == 0, make sure we get to
13197 the first character in the line after the newline.
13199 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
13201 * ccl.c: Improve and simplify overflow checking (Bug#9196).
13202 (ccl_driver): Do not generate an out-of-range pointer.
13203 (Fccl_execute_on_string): Remove unnecessary check for
13204 integer overflow, noted by Stefan Monnier in
13205 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
13206 Remove a FIXME that didn't need fixing.
13207 Simplify the newly-introduced buffer reallocation code.
13209 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
13211 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
13213 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
13215 Integer and memory overflow issues (Bug#9196).
13217 * doc.c (get_doc_string): Rework so that
13218 get_doc_string_buffer_size is the actual buffer size, rather than
13219 being 1 less than the actual buffer size; this makes xpalloc more
13222 * image.c (x_allocate_bitmap_record, cache_image):
13223 * xselect.c (Fx_register_dnd_atom):
13224 Simplify previous changes by using xpalloc.
13226 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
13227 since either will do and ptrdiff_t is convenient with xpalloc.
13229 * charset.c (charset_table_size)
13230 (struct charset_sort_data.priority): Now ptrdiff_t.
13231 (charset_compare): Don't overflow if priorities differ greatly.
13232 (Fsort_charsets): Don't assume list length fits in int.
13233 Check for size-calculation overflow when allocating sort data.
13234 (syms_of_charset): Allocate an initial charset table that is
13235 just under 64 KiB, to avoid problems with glibc malloc and mmap.
13237 * cmds.c (internal_self_insert): Check for size-calculation overflow.
13239 * composite.h (struct composition.glyph_len): Now int, not unsigned.
13240 The actual value is always <= INT_MAX, and leaving it unsigned made
13241 overflow checking harder.
13243 * dispextern.h (struct glyph_matrix.rows_allocated)
13244 (struct face_cache.size): Now ptrdiff_t, for convenience in use
13245 with xpalloc. The values are still always <= INT_MAX.
13247 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
13249 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
13250 (SAFE_NALLOCA): New macro.
13252 * region-cache.c (struct boundary.pos, find_cache_boundary)
13253 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
13254 (set_cache_region, invalidate_region_cache)
13255 (revalidate_region_cache, know_region_cache, region_cache_forward)
13256 (region_cache_backward, pp_cache):
13257 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
13258 so that ptrdiff_t * can be passed to xpalloc.
13259 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
13260 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
13261 (pp_cache): Don't assume cache_len fits in int.
13262 * region-cache.h: Adjust extern decls to match.
13264 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
13265 EMACS_INT, since either will do, for xpalloc.
13267 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
13268 (xnmalloc, xnrealloc, xpalloc): New functions.
13270 * bidi.c (bidi_shelve_header_size): New constant.
13271 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
13272 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
13274 * bidi.c (bidi_cache_shrink):
13275 * buffer.c (overlays_at, overlays_in, record_overlay_string)
13277 Don't update size of array until after memory allocation succeeds,
13278 because xmalloc/xrealloc may not return.
13279 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
13280 now that we have proper integer overflow checking.
13281 (record_overlay_string, overlay_strings): Catch overflows when
13282 calculating size of overlay_str_buf.
13284 * callproc.c (Fcall_process): Check for size overflow when
13285 calculating size of args2.
13286 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
13287 Normally we prefer signed values, but sticking with ptrdiff_t would
13288 require adding more-complicated checks.
13290 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
13291 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
13292 Redo buffer-overflow calculations to avoid integer overflow.
13293 Add a FIXME comment where memory seems to be over-allocated.
13295 * character.c (Fstring): Check for size-calculation overflow.
13297 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
13298 unnecessary integer overflow. Check for size overflow.
13299 (encode_coding_object): Don't update size until xmalloc succeeds.
13301 * composite.c (get_composition_id): Check for overflow in glyph
13302 length calculations.
13304 Integer and memory overflow fixes for display code.
13305 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
13306 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
13307 (scrolling_window): Check for overflow in size calculations.
13308 (line_draw_cost, realloc_glyph_pool, add_row_entry):
13309 Don't assume glyph table len fits in int.

13311 (row_table_size): Now ptrdiff_t, not int.
13312 (scrolling_window): Avoid overflow in size calculations.
13313 Don't update size until allocation succeeds.
13314 * fns.c (concat): Check for overflow in size calculations.
13315 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
13316 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
13317 (NEXT_ALMOST_PRIME_LIMIT): New constant.
13319 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
13320 (get_doc_string): Check for size calculation overflow.
13321 Don't update size until allocation succeeds.
13322 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
13323 EMACS_INT, where ptrdiff_t will do.
13324 (Fsubstitute_command_keys): Check for string overflow.
13326 * editfns.c (set_time_zone_rule): Don't assume environment length
13328 (message_length): Now ptrdiff_t, not int.
13329 (Fmessage_box): Don't update size until allocation succeeds.
13330 Don't assume message length fits in int.
13331 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
13333 * emacs.c (main): Do not reallocate argv, since there is a null at
13334 the end that can be overwritten, and this way there's no need to
13335 worry about size-calculation overflow.
13336 (sort_args): Check for size-calculation overflow.
13338 * eval.c (init_eval_once, grow_specpdl): Don't update size until
13340 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
13342 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
13343 (x_set_scroll_bar_width, x_figure_window_size):
13344 Check for integer overflow.
13345 (x_set_alpha): Do not assume XINT fits in int.
13347 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
13348 This is for the members text_lines, text_cols, total_lines, total_cols,
13349 where the system imposes an 'int' limit.
13351 * fringe.c (Fdefine_fringe_bitmap):
13352 Don't update size until alloc works.
13354 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
13355 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
13357 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
13358 Check for size-calculation overflow.
13359 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
13360 do, as we prefer signed integers.
13361 (id_to_widget.max_size, id_to_widget.used)
13362 (xg_store_widget_in_map, xg_remove_widget_from_map)
13363 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
13364 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
13365 Use and return ptrdiff_t, not int.
13366 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
13367 * gtkutil.h: Change prototypes to match the above.
13369 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
13370 are duplicate now that they've been promoted to lisp.h.
13371 (x_allocate_bitmap_record, x_alloc_image_color)
13372 (make_image_cache, cache_image, xpm_load):
13373 Don't update size until alloc is done.
13374 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
13376 Check for size calculation overflow.
13377 (ct_colors_allocated_max): New constant.
13378 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
13381 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
13382 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
13383 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
13384 Use ptrdiff_t, not int, to count maps.
13385 (read_char_minibuf_menu_prompt): Check for overflow in size
13386 calculations. Don't update size until allocation succeeds.
13387 Redo calculations to avoid overflow.
13388 * keyboard.h: Change prototypes to match the above.
13390 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
13392 (current_minor_maps): Check for size calculation overflow.
13393 * keymap.h: Change prototypes to match the above.
13395 * lread.c (read1, init_obarray): Don't update size until alloc done.
13397 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
13398 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
13400 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
13401 Now ptrdiff_t, not int.
13402 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.
13403 (ns_draw_fringe_bitmap): Rewrite to avoid overflow.
13405 * process.c (Fnetwork_interface_list): Check for overflow
13406 in size calculation.
13408 * region-cache.c (move_cache_gap): Check for size calculation overflow.
13410 * scroll.c (do_line_insertion_deletion_costs): Check for size calc
13411 overflow. Don't bother calling xmalloc when xrealloc will do.
13413 * search.c (Freplace_match): Check for size calculation overflow.
13414 (Fset_match_data): Don't assume list lengths fit in 'int'.
13416 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
13417 for command line length. Do not attempt to address one before the
13418 beginning of an array, as that's not portable.
13420 * term.c (max_frame_lines): Remove; unused.
13421 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
13423 (encode_terminal_code, calculate_costs): Check for size
13424 calculation overflow.

13427 done. Redo calculations to avoid overflow.
13428 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
13430 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
13431 subtracting pointers.

13435 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
13436 Don't update size until alloc done.
13437 Redo size calculations to avoid overflow.
13438 Check for size calculation overflow.
13439 (main) [DEBUG]: Fix typo in invoking tparam1.

13446 Use ptrdiff_t, not int, for sizes.
13447 (Finternal_make_lisp_face, cache_face):
13448 Check for size calculation overflow.
13449 (cache_face): Treat size calculation overflows as if they were
13450 memory exhaustion (the usual treatment), rather than aborting.
13452 * xfns.c (x_encode_text, x_set_name_internal)
13453 (Fx_change_window_property): Use ptrdiff_t, not int, to count
13454 sizes, since they can exceed INT_MAX in size. Check for size
13455 calculation overflow.
13457 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
13458 (xg_select): Check for size calculation overflow.
13459 Don't update size until alloc done.
13461 * xrdb.c (get_environ_db): Don't assume path length fits in int,
13462 as sprintf is limited to int lengths.
13464 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
13465 (X_LONG_MIN): New macros.
13466 Use them to make the following changes clearer.
13467 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
13468 This change doesn't affect the value now, but it may help remind
13469 future maintainers not to raise the value too much later.
13470 (SELECTION_QUANTUM): Remove, replacing with ...
13471 (selection_quantum): ... new function, which avoids overflow.
13473 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
13474 assumption that selection length fits in 'int'.
13475 (x_reply_selection_request, x_handle_selection_request)
13476 (x_get_window_property, receive_incremental_selection)
13477 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
13478 (lisp_data_to_selection_data, clean_local_selection_data):

13480 (x_reply_selection_request, x_get_window_property)
13481 (receive_incremental_selection, x_property_data_to_lisp):
13482 Redo calculations to avoid overflow.
13483 (x_reply_selection_request): When sending hint, ceiling it at
13484 X_LONG_MAX rather than relying on wraparound overflow to send
13486 (x_get_window_property, receive_incremental_selection)
13487 (lisp_data_to_selection_data, x_property_data_to_lisp):
13488 Check for size-calculation overflow.
13489 (x_get_window_property, receive_incremental_selection)

13491 Don't store size until memory allocation succeeds.
13492 (x_get_window_property): Plug memory leak on memory exhaustion.
13493 Don't double-block input; malloc is safe here. Don't assume 2**34
13494 - 4 fits in unsigned long. Add an xassert to check
13495 XGetWindowProperty overflow. Be more careful about overflow
13496 calculations, and distinguish size from memory overflow better.
13497 (receive_incremental_selection): When tracing, don't assume
13498 unsigned int is less than INT_MAX.
13499 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
13500 harmful) conversions of unsigned short to int.
13501 (lisp_data_to_selection_data): Don't assume that integers
13502 in the range -65535 through -1 fit in an X unsigned short.
13503 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
13504 result parameters unless successful. Rely on cons_to_unsigned
13505 to report problems with elements; the old code wasn't right anyway.
13506 (x_check_property_data): Check for int overflow; we cannot use
13507 a wider type due to X limits.
13508 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
13510 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
13512 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
13513 (x_term_init): Check for size calculation overflow.
13514 (x_color_cells): Don't store size until memory allocation succeeds.
13515 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
13516 Don't assume alloca size is less than MAX_ALLOCA.
13517 (x_term_init): Don't assume length fits in int (sprintf is limited
13520 Use ptrdiff_t for composition IDs.

13540 * lisp.h (hash_lookup, hash_put):
13541 * minibuf.c (Ftest_completion):
13542 Use ptrdiff_t for hash table indexes, not int (which is too
13543 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
13544 32-bit --with-wide-int hosts).
13546 * charset.c (Fdefine_charset_internal): Check for integer overflow.
13547 Add a FIXME comment about memory leaks.
13548 (syms_of_charset): Don't assume xmalloc returns.

13555 with outlandish widths.
13556 * character.h (sanitize_tab_width): Rename from sanitize_width,
13557 now that we have two such functions. All uses changed.

13575 * xterm.c: Don't go over XClientMessageEvent limit.
13576 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
13577 (x_send_scroll_bar_event): Likewise. Check that the size does not
13578 exceed limits imposed by XClientMessageEvent, as well as the usual
13579 ptrdiff_t and size_t limits.
13581 * keyboard.c: Overflow, signedness and related fixes.
13582 (make_lispy_movement): Use same integer type in forward decl
13583 that is used in the definition.
13584 (read_key_sequence, keyremap_step):
13585 Change bufsize argument back to int, undoing my 2011-03-30 change.
13586 We prefer signed types, and int is wide enough here.
13587 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
13588 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
13589 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
13590 length, not size_t. Use ptrdiff_t for index, not int.
13591 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
13592 possibility of integer overflow.
13594 Overflow, signedness and related fixes for images.
13596 * dispextern.h (struct it.stack[0].u.image.image_id)

13615 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
13616 (lookup_image): Remove unnecessary tests.
13617 (xbm_image_p): Locals are now of int, not EMACS_INT,
13618 since parse_image_check makes sure they fit into int.
13619 (png_load, gif_load, svg_load_image):
13620 Prefer int to unsigned where either will do.
13621 (tiff_handler): New function, combining the cores of the
13622 old tiff_error_handler and tiff_warning_handler.
13623 This function is rewritten to use vsnprintf and thereby avoid
13624 stack buffer overflows. It uses only the features of vsnprintf
13625 that are common to both POSIX and native Microsoft.
13626 (tiff_error_handler, tiff_warning_handler): Use it.
13627 (tiff_load, gif_load, imagemagick_load_image):
13628 Don't assume :index value fits in 'int'.
13629 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
13630 (imagemagick_load_image): Check that crop parameters fit into
13631 the integer types that MagickCropImage accepts. Don't assume
13632 Vimagemagick_render_type has a nonnegative value. Don't assume
13633 size_t fits in 'long'.
13634 (gs_load): Use printmax_t to print the widest integers possible.
13635 Check for integer overflow when computing image height and width.

13647 handle_single_display_spec, not just 1 or zero.
13648 (handle_single_display_spec): If the display spec is of the form
13649 `(space ...)', and specifies display in the text area, return 2
13651 (try_cursor_movement): Check for the need to scroll more
13652 accurately, and prefer exact match for point under bidi.
13653 Don't advance `row' beyond the last row of the window.
13655 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
13656 into disp_prop; all users changed.

13670 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
13671 buffers, return left-to-right.
13672 (set_cursor_from_row): Consider candidate row a win if its glyph
13673 represents a newline and point is on that newline. Fixes cursor
13674 positioning on the newline at EOL of R2L text within L2R
13675 paragraph, and vice versa.
13676 (try_cursor_movement): Check continued rows, in addition to
13677 continuation rows. Fixes unwarranted scroll when point enters a
13678 continued line of R2L text within an L2R paragraph, or vice versa.
13679 (cursor_row_p): Consider the case of point being equal to
13680 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
13681 from the end of a short line to the beginning of a continued line
13682 of R2L text within L2R paragraph.
13683 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
13684 composed characters.

13709 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
13710 instead of CHAR_TO_BYTE. Fixes a crash when a completion
13711 candidate is selected by the mouse, and that candidate has a
13712 composed character under the mouse.
13714 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
13715 coordinates reported by pos-visible-in-window-p for a composed
13716 character in column zero.
13718 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

13722 2011-08-22 Eli Zaretskii <eliz@gnu.org>
13724 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
13725 consider it a hit if to_charpos is anywhere in the range of the
13726 composed buffer positions.
13728 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
13730 * image.c (gif_load): Don't assume that each subimage has the same
13731 dimensions as the base image. Handle disposal method that is
13732 "undefined" by the gif spec (Bug#9335).
13734 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
13736 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

13742 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
13743 from an Org mode buffer to a Speedbar frame.
13745 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
13746 a composition, take its buffer position from IT->cmp_it.charpos.
13747 Fixes cursor positioning at the beginning of a line that begins
13748 with a composed character.
13750 2011-08-18 Eli Zaretskii <eliz@gnu.org>
13752 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
13753 character bidirectional type, use STRONG_L instead. Fixes crashes
13754 in a buffer produced by `describe-categories'.
13756 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
13757 members before the level stack, so they would be saved and
13758 restored when copying iterator state. Fixes incorrect reordering
13759 around TABs covered by display properties.
13761 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

13787 Fix memory allocation problems in Cygwin build (Bug#9273).
13789 * unexcw.c ( __malloc_initialized): Declare external variable.
13790 (fixup_executable): Force the dumped emacs to reinitialize malloc.
13792 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
13794 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the

13833 * xdisp.c (move_it_in_display_line_to): Don't invoke
13834 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
13835 ppos_it. Fixes vertical cursor motion when line beginning is
13836 covered by an image. (Bug#9296)
13838 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>

13847 the event loop. Get status from as_status (Bug#7276).
13849 * nsterm.m (sendEvent): If event is NSApplicationDefined and
13850 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
13851 the event loop (Bug#7276).

13855 * gnutls.c (QCgnutls_bootprop_priority)
13856 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
13857 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
13858 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
13859 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
13860 (QCgnutls_bootprop_verify_hostname_error)
13861 (QCgnutls_bootprop_callbacks_verify): Rename from
13862 Qgnutls_bootprop_..., all uses changed.
13864 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
13867 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
13869 * xfaces.c (Qframe_set_background_mode): Now static.
13870 * dispextern.h (Qframe_set_background_mode): Remove decl.
13872 * process.c (Fnetwork_interface_info): Declare local only if needed.
13874 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
13876 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
13877 (Fnetwork_interface_list): Allocate in increments of bytes instead
13878 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
13879 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
13881 (struct ifflag_def): notrailers is smart on OSX.
13882 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
13883 Get hardware address with getifaddrs if available.
13885 2011-08-12 Eli Zaretskii <eliz@gnu.org>
13887 * xdisp.c (iterate_out_of_display_property): xassert that
13888 IT->position is set to within IT->object's boundaries. Break from
13889 the loop as soon as EOB is reached; avoids infloops in redisplay
13890 when IT->position is set up wrongly due to some bug.
13891 Set IT->current to match the bidi iterator unconditionally.
13892 (push_display_prop): Allow GET_FROM_STRING as IT->method on
13893 entry. Force push_it to save on the stack the current
13894 buffer/string position, to be restored by pop_it. Fix flags in
13895 the iterator structure wrt the object coming from a display
13896 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
13897 properties. (Bug#9284)
13899 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
13901 * fontset.c (fontset_get_font_group): Add proper type checks.
13904 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13906 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
13907 and LC_VERSION_MIN_MACOSX.
13908 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
13909 (dump_it) [LC_FUNCTION_STARTS]: Use it.
13911 2011-08-08 Eli Zaretskii <eliz@gnu.org>
13913 * xdisp.c (forward_to_next_line_start): Allow to use the
13914 no-display-properties-and-no-overlays under bidi display.
13915 Set disp_pos in the bidi iterator to avoid searches for display
13916 properties and overlays.
13918 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
13920 * editfns.c (Fset_time_zone_rule): Document relationship with the
13923 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
13924 the font entity extracted from the cache (Bug#8109).
13926 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
13928 * composite.c (autocmp_chars): Don't reset point. That is done by
13929 restore_point_unwind (Bug#5984).
13931 2011-08-07 Juri Linkov <juri@jurta.org>
13933 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
13934 to show the arg `TIME' instead of `TIMEVAL'.
13936 2011-08-06 Eli Zaretskii <eliz@gnu.org>
13938 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
13939 display property strides EOL and includes a newline, as in
13940 longlines-mode. (Bug#9254)
13941 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
13942 word-wrap under bidirectional display. (Bug#9224)
13944 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
13945 is non-zero, even if the data buffer is NULL. Fixes a crash in
13946 vertical-motion with longlines-mode. (Bug#9254)
13948 2011-08-05 Eli Zaretskii <eliz@gnu.org>
13950 * bidi.c <bidi_cache_total_alloc>: Now static.
13951 (bidi_initialize): Initialize bidi_cache_total_alloc.
13953 * xdisp.c (display_line): Release buffer allocated for shelved bidi
13956 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
13957 amount allocated this far in `bidi_cache_total_alloc'.
13958 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
13959 non-zero, only free the data buffer without restoring the cache
13960 contents. All callers changed.
13962 * dispextern.h (bidi_unshelve_cache): Update prototype.
13964 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
13965 (move_it_in_display_line, move_it_to)
13966 (move_it_vertically_backward, move_it_by_lines): Replace the call
13967 to xfree to an equivalent call to bidi_unshelve_cache.
13968 (move_it_in_display_line_to): Fix logic of returning
13969 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
13971 2011-08-05 Eli Zaretskii <eliz@gnu.org>
13973 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
13974 came from a string character with a `cursor' property. (Bug#9229)
13976 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
13978 * Makefile.in (LIB_PTHREAD): New variable.
13979 (LIBES): Add LIB_PTHREAD (Bug#9216).
13981 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
13982 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
13984 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
13986 * regex.c (re_iswctype): Remove some redundant boolean conversions.
13988 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
13990 * xterm.c (x_find_topmost_parent): New function.
13991 (x_set_frame_alpha): Find topmost parent window with
13992 x_find_topmost_parent and set the property there also (bug#9181).
13993 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
13995 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
13997 * callproc.c (Fcall_process): Avoid vfork clobbering
13998 the local vars buffer, coding_systems, current_dir.
14000 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
14002 * keymap.c (Fmake_composed_keymap): Move to subr.el.
14004 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
14006 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
14007 so that it is not optimized away.
14009 * xdisp.c (compute_display_string_pos): Remove unused local.
14011 2011-08-02 Eli Zaretskii <eliz@gnu.org>
14013 Fix slow cursor motion and scrolling in large buffers with
14014 selective display, like Org Mode buffers. (Bug#9218)
14016 * dispextern.h (struct bidi_it): New member disp_prop_p.
14018 * xdisp.c: Remove one-slot cache of display string positions.
14019 (compute_display_string_pos): Accept an additional argument
14020 DISP_PROP_P; callers changed. Scan at most 5K characters forward
14021 for a display string or property. If found, set DISP_PROP_P
14024 * bidi.c (bidi_fetch_char): Accept an additional argument
14025 DISP_PROP_P, and pass it to compute_display_string_pos.
14026 Only handle text covered by a display string if DISP_PROP_P is returned
14027 non-zero. All callers of bidi_fetch_char changed.
14029 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
14031 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
14033 2010-12-03 Don March <don@ohspite.net>
14035 * keymap.c (Fdefine_key): Fix non-prefix key error message when
14036 last character M-[char] is translated to ESC [char] (bug#7541).
14038 2011-08-02 Kenichi Handa <handa@m17n.org>
14040 * lisp.h (uniprop_table): Extern it.
14042 * chartab.c (uniprop_table): Make it non-static.
14044 2011-08-01 Eli Zaretskii <eliz@gnu.org>
14046 * xdisp.c (forward_to_next_line_start): Accept additional argument
14047 BIDI_IT_PREV, and store into it the state of the bidi iterator had
14049 (reseat_at_next_visible_line_start): Use the bidi iterator state
14050 returned by forward_to_next_line_start to restore the state of
14051 it->bidi_it after backing up to previous newline. (Bug#9212)
14053 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
14055 * regex.c (re_comp): Protoize.
14056 (re_exec): Fix return type.
14057 (regexec): Fix type of `ret'. (Bug#9203)
14059 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14061 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
14062 This is needed if max-image-size is a floating-point number.
14064 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
14066 * print.c (print_object): Print empty symbol as ##.
14068 * lread.c (read1): Read ## as empty symbol.
14070 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
14072 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
14073 setting frame foreground color (Bug#9175).
14074 (x_set_background_color): Likewise.
14076 * nsmenu.m (-setText): Size tooltip dimensions precisely to
14077 contents (Bug#9176).
14078 (EmacsTooltip -init): Remove bezels and add shadows to
14081 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
14082 or scroll bar (Bug#8470).
14084 * nsfont.m (nsfont_open): Remove assignment to voffset and
14085 unnecessary vars hshink, expand, hd, full_height, min_height.
14086 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
14088 * nsterm.h (nsfont_info): Remove voffset field.
14090 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
14092 Implement strike-through and overline on NextStep (Bug#8863).
14094 * nsfont.m (nsfont_open): Use underline position provided by font,
14095 instead of hard-coded value of 2.
14096 (nsfont_draw): Call ns_draw_text_decoration instead.
14098 * nsterm.h: Add declaration for ns_draw_text_decoration.
14100 * nsterm.m (ns_draw_text_decoration): New function for drawing
14101 underline, overline, and strike-through.
14102 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
14103 ns_draw_text_decoration. Change treatment of cursor drawing to
14104 accommodate underlining, etc.
14106 2011-07-28 Eli Zaretskii <eliz@gnu.org>
14108 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
14111 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14113 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
14114 Without this fix, if a signal arrives just after memory fills up,
14115 'malloc' might be invoked reentrantly.
14117 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
14118 In other words, assume that every image size is allowed, on non-X
14119 hosts. This assumption is probably wrong, but it lets Emacs compile.
14121 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
14123 * regex.c (re_iswctype): Convert return values to boolean.
14125 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
14127 * xdisp.c (compute_display_string_pos): Don't use cached display
14128 string position if the buffer had its restriction changed.
14131 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14133 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
14135 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14137 Integer signedness and overflow and related fixes. (Bug#9079)
14139 * bidi.c: Integer size and overflow fixes.
14140 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
14141 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
14142 (bidi_cache_find_level_change, bidi_cache_ensure_space)
14143 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
14144 (bidi_find_other_level_edge):
14145 Use ptrdiff_t instead of EMACS_INT where either will do.
14146 This works better on 32-bit hosts configured --with-wide-int.
14147 (bidi_cache_ensure_space): Check for size-calculation overflow.
14148 Use % rather than repeated addition, for better worst-case speed.
14149 Don't set bidi_cache_size until after xrealloc returns, because it
14151 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
14152 (bidi_cache_ensure_space): Also check that the bidi cache size
14153 does not exceed that of the largest Lisp string or buffer. See Eli
14154 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
14156 * alloc.c (__malloc_size_t): Remove.
14157 All uses replaced by size_t. See Andreas Schwab's note
14158 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
14160 * image.c: Improve checking for integer overflow.
14161 (check_image_size): Assume that f is nonnull, since
14162 it is always nonnull in practice. This is one less thing to
14163 worry about when checking for integer overflow later.
14164 (x_check_image_size): New function, which checks for integer
14165 overflow issues inside X.
14166 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
14167 This removes the need for a memory_full check.
14168 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
14169 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
14170 (xbm_read_bitmap_data): Change locals back to 'int', since
14171 their values must fit in 'int'.
14172 (xpm_load_image, png_load, tiff_load):
14173 Invoke x_create_x_image_and_pixmap earlier,
14174 to avoid much needless work if the image is too large.
14175 (tiff_load): Treat overly large images as if
14176 x_create_x_image_and_pixmap failed, not as malloc failures.
14177 (gs_load): Use x_check_image_size.
14179 * gtkutil.c: Omit integer casts.
14180 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
14181 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
14183 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
14185 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
14186 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
14187 would wrongly return t on a 64-bit host.
14189 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
14190 The plain *_OVERFLOW macros run afoul of GCC bug 49705
14191 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
14192 and therefore cause GCC to emit a bogus diagnostic in some cases.
14194 * image.c: Integer signedness and overflow and related fixes.
14195 This is not an exhaustive set of fixes, but it's time to
14196 record what I've got.
14197 (lookup_pixel_color, check_image_size): Remove redundant decls.
14198 (check_image_size): Don't assume that arbitrary EMACS_INT values
14199 fit in 'int', or that arbitrary 'double' values fit in 'int'.
14200 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
14201 (tiff_load, imagemagick_load_image):
14202 Check for overflow in size calculations.
14203 (x_create_x_image_and_pixmap): Remove unnecessary test for
14204 xmalloc returning NULL; that can't happen.
14205 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
14206 (xpm_color_bucket): Use better integer hashing function.
14207 (xpm_cache_color): Don't possibly over-allocate memory.
14208 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
14209 (gif_memory_source):
14210 Use ptrdiff_t, not int or size_t, to record sizes.
14211 (png_load): Don't assume values greater than 2**31 fit in 'int'.
14212 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
14213 either works, as we prefer signed integers.
14214 (tiff_read_from_memory, tiff_write_from_memory):
14215 Return tsize_t, not size_t, since that's what the TIFF API wants.
14216 (tiff_read_from_memory): Don't fail simply because the read would
14217 go past EOF; instead, return a short read.
14218 (tiff_load): Omit no-longer-needed casts.
14219 (Fimagemagick_types): Don't assume size fits into 'int'.
14221 Improve hashing quality when configured --with-wide-int.
14222 * fns.c (hash_string): New function, taken from sxhash_string.
14223 Do not discard information about ASCII character case; this
14224 discarding is no longer needed.
14225 (sxhash-string): Use it. Change sig to match it. Caller changed.
14226 * lisp.h: Declare it.
14227 * lread.c (hash_string): Remove, since we now use fns.c's version.
14228 The fns.c version returns a wider integer if --with-wide-int is
14229 specified, so this should help the quality of the hashing a bit.
14231 * emacs.c: Integer overflow minor fix.
14232 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
14233 Define only if GNU_LINUX.
14234 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
14236 * dispnew.c: Integer signedness and overflow fixes.
14237 Remove unnecessary forward decls, that were a maintenance hassle.
14238 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
14240 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
14241 (scrolling_window): Use ptrdiff_t, not int, for byte count.
14242 (prepare_desired_row, line_draw_cost):
14243 Use int, not unsigned, where either works.
14244 (save_current_matrix, restore_current_matrix):
14245 Use ptrdiff_t, not size_t, where either works.
14246 (init_display): Check for overflow more accurately, and without
14247 relying on undefined behavior.
14249 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
14250 Remove, replacing with the new symbols in lisp.h. All uses changed.
14251 * fileio.c (make_temp_name):
14252 * filelock.c (lock_file_1, lock_file):
14253 * xdisp.c (message_dolog):
14254 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
14255 Use pMd etc. instead.
14256 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
14257 replacing the pWIDE etc. symbols removed from editfns.c.
14259 * keyboard.h (num_input_events): Now uintmax_t.
14260 This is (very slightly) less likely to mess up due to wraparound.
14263 * buffer.c: Integer signedness fixes.
14264 (alloc_buffer_text, enlarge_buffer_text):
14265 Use ptrdiff_t rather than size_t when either will do, as we prefer
14268 * alloc.c: Integer signedness and overflow fixes.
14269 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
14270 (__malloc_size_t): Default to size_t, not to int.
14271 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
14272 (Fgarbage_collect, mark_object_loop_halt, mark_object):
14273 Prefer ptrdiff_t to size_t when either would do, as we prefer
14275 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
14276 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
14277 Now const. Initialize with values that are in range even if char
14279 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
14280 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
14281 These functions do the right thing with sizes > 2**32.
14282 (check_depth): Now ptrdiff_t, not int.
14283 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
14284 Adjust to new way of storing sizes. Check for size overflow bugs
14286 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
14287 slightly wrong anyway, as it missed one instance of
14288 XMALLOC_OVERRUN_CHECK_OVERHEAD.
14289 (refill_memory_reserve): Omit needless cast to size_t.
14290 (mark_object_loop_halt): Mark as externally visible.
14292 * xselect.c: Integer signedness and overflow fixes.
14293 (Fx_register_dnd_atom, x_handle_dnd_message):
14294 Use ptrdiff_t, not size_t, since we prefer signed.
14295 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
14296 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
14297 x_dnd_atoms_size and x_dnd_atoms_length.
14299 * doprnt.c: Prefer signed to unsigned when either works.
14301 * doprnt.c (doprnt):
14303 * xdisp.c (vmessage):
14304 Use ptrdiff_t, not size_t, when using or implementing doprnt,
14305 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
14306 prefer signed arithmetic to avoid comparison confusion.
14307 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
14308 but is a bit tricky.
14310 Assume freestanding C89 headers, string.h, stdlib.h.
14311 * data.c, doprnt.c, floatfns.c, print.c:
14312 Include float.h unconditionally.
14313 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
14314 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
14315 * regex.c: Likewise for stddef.h, string.h.
14316 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
14317 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
14318 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
14319 (STDC_HEADERS): Remove obsolete defines.
14320 * sysdep.c: Include limits.h unconditionally.
14322 Assume support for memcmp, memcpy, memmove, memset.
14323 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
14324 * regex.c (memcmp, memcpy):
14325 Remove; we assume C89 now.
14327 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
14328 (__malloc_safe_bcopy): Remove; no longer needed.
14330 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
14331 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
14332 well either way, and we prefer signed to unsigned.
14334 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
14336 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
14337 closes the connection while we're reading (bug#9182).
14339 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
14341 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
14342 are specified (Bug#9168).
14344 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
14346 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
14347 Found by GCC static checking and --with-wide-int on a 32-bit host.
14349 2011-07-25 Eli Zaretskii <eliz@gnu.org>
14351 * xdisp.c (compute_display_string_pos): Fix logic of caching
14352 previous display string position. Initialize cached_prev_pos to
14353 -1. Fixes slow-down at the beginning of a buffer.
14355 2011-07-24 Eli Zaretskii <eliz@gnu.org>
14357 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
14358 for attrs[LFACE_FONTSET_INDEX].
14360 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
14362 * xml.c (parse_region): Remove unused local
14363 that was recently introduced.
14365 2011-07-23 Eli Zaretskii <eliz@gnu.org>
14367 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
14368 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
14370 * xdisp.c (move_it_in_display_line_to): Record the best matching
14371 position for TO_CHARPOS while scanning the line, and restore it on
14372 exit if none of the characters scanned was an exact match.
14373 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
14374 when exact match is impossible due to invisible text, and the
14375 lines are truncated.
14377 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
14379 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
14382 2011-07-22 Eli Zaretskii <eliz@gnu.org>
14384 Fix a significant slow-down of cursor motion with C-n, C-p,
14385 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
14386 auto-repeat under bidi redisplay in fontified buffers.
14387 * xdisp.c (compute_stop_pos_backwards): New function.
14388 (next_element_from_buffer): Call compute_stop_pos_backwards to
14389 find a suitable prev_stop when we find ourselves before
14391 (reseat): Don't look for prev_stop, as that could mean a very long
14393 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
14394 <cached_disp_overlay_modiff>: Cache for last found display string
14396 (compute_display_string_pos): Return the cached position if asked
14397 about the same buffer in the same area of character positions, and
14398 the buffer wasn't changed since the time the display string
14399 position was cached.
14401 2011-07-22 Eli Zaretskii <eliz@gnu.org>
14403 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
14404 is an integer, which is important for empty lines. (Bug#9149)
14406 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
14408 * frame.c (Fmodify_frame_parameters): In tty case, update the
14409 default face if necessary (Bug#4238).
14411 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
14413 * editfns.c (Fstring_to_char): No need to explain what a character
14414 is in the docstring (Bug#6576).
14416 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
14418 * xml.c (parse_region): Make sure we always return a tree.
14420 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
14422 * xml.c (parse_region): If a document contains only comments,
14425 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
14427 * xml.c (make_dom): Return comments, too.
14429 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
14432 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
14433 and the surrounding thread.
14434 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
14435 rather than fgets, and retry after EINTR. Otherwise, 'emacs
14436 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
14438 * s/openbsd.h (BROKEN_SIGIO): Define.
14439 * unexelf.c (unexec) [__OpenBSD__]:
14440 Don't update the .mdebug section of the Alpha COFF symbol table.
14442 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14444 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
14447 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
14449 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
14450 This fixes some race conditions on the permissions of any newly
14453 * alloc.c (valid_pointer_p): Use pipe, not open.
14454 This fixes some permissions issues when debugging.
14456 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
14457 If fchown fails to set both uid and gid, try to set just gid,
14458 as that is sometimes allowed. Adjust the file's mode to eliminate
14459 setuid or setgid bits that are inappropriate if fchown fails.
14461 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
14463 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
14464 to compare Lisp_Objects.
14465 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
14466 global_gnutls_log_level, don't mistake it for a Lisp_Object.
14467 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
14469 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
14471 * lread.c (read_integer): Unread even EOF character.
14472 (read1): Likewise. Properly record start position of symbol.
14474 * lread.c (read1): Read `#:' as empty uninterned symbol if no
14475 symbol character follows.
14477 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
14479 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
14480 This works around a problem with the previous change to Fcopy_file.
14481 Recent glibc declares fchown with __attribute__((warn_unused_result)),
14482 and without this change, GCC might complain about discarding
14483 fchown's return value.
14485 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
14487 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
14489 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
14491 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
14493 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
14495 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
14496 it's used from the C level.
14498 * process.c: Use the same condition for POLL_FOR_INPUT in both
14499 keyboard.c and process.c (bug#1858).
14501 2011-07-09 Lawrence Mitchell <wence@gmx.li>
14503 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
14504 (Fgnutls_boot): Use it.
14506 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
14508 * doc.c (Fsubstitute_command_keys): Revert last change.
14510 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
14512 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
14513 quotes the next character, and doesn't affect other longer
14514 sequences (bug#8935).
14516 * lread.c (syms_of_lread): Clarify that is isn't only
14517 `eval-buffer' and `eval-defun' that's affected by
14518 `lexical-binding' (bug#8460).
14520 2011-07-15 Eli Zaretskii <eliz@gnu.org>
14522 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
14523 bidi redisplay when a line includes both an image and is truncated.
14525 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
14527 Fix minor problems found by static checking.
14528 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
14529 (elsz): Now a signed constant, not a size_t var. We prefer signed
14530 types to unsigned, to avoid integer comparison confusion. Without
14531 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
14532 "cannot optimize loop, the loop counter may overflow", a symptom
14534 * indent.c (Fvertical_motion): Mark locals as initialized.
14535 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
14537 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
14539 * search.c (Fre_search_backward): Mention `case-fold-search' in
14540 all the re_search_* functions (bug#8138).
14542 * keyboard.c (Fopen_dribble_file): Document when the file is

14555 bidi_it->string.schars.
14556 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
14557 NULL (avoids a crash in bidi_paragraph_init).
14558 Initialize itb.string.lstring.
14559 (init_iterator): Call bidi_init_it only of a valid
14560 buffer position was specified. Initialize paragraph_embedding to
14562 (reseat_to_string): Initialize the bidi iterator.
14563 (display_string): If we need to ignore text properties of
14564 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
14565 original value of -1 will not work with bidi.)
14566 (compute_display_string_pos): First arg is now struct
14567 `text_pos *'; all callers changed. Support display properties on
14569 (compute_display_string_end): Support display properties on Lisp
14571 (init_iterator, reseat_1, reseat_to_string): Initialize the
14572 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
14573 when iterating on a string not from display properties).
14574 (compute_display_string_pos, compute_display_string_end):
14575 Fix calculation of the object to scan. Fixes an error when using
14577 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
14578 base_level_stop; instead, set base_level_stop to BEGV.
14579 Fixes crashes in vertical-motion.
14580 (next_element_from_buffer): Improve commentary for when
14581 the iterator is before prev_stop.
14582 (init_iterator): Initialize bidi_p from the default value of
14583 bidi-display-reordering, not from buffer-local value. Use the
14584 buffer-local value only if initializing for buffer iteration.
14585 (handle_invisible_prop): Support invisible properties on strings
14586 that are being bidi-reordered.
14587 (set_iterator_to_next): Support bidi reordering of C strings and
14589 (next_element_from_string): Support bidi reordering of Lisp
14591 (handle_stop_backwards): Support Lisp strings as well.
14592 (display_string): Support display of R2L glyph rows.
14593 Use IT_STRING_CHARPOS when displaying from a Lisp string.
14594 (init_iterator): Don't initialize it->bidi_p for strings
14596 (reseat_to_string): Initialize it->bidi_p for strings here.
14597 (next_element_from_string, next_element_from_c_string)
14598 (next_element_from_buffer): Add xassert's for correspondence
14599 between IT's object being iterated and it->bidi_it.string

14602 (next_element_from_c_string): Handle the case of the first string
14603 character that is not the first one in the visual order.
14604 (get_visually_first_element): New function, refactored from common
14605 parts of next_element_from_buffer, next_element_from_string, and
14606 next_element_from_c_string.
14607 (tool_bar_lines_needed, redisplay_tool_bar)
14608 (display_menu_bar): Force left-to-right direction. Add a FIXME
14609 comment for making that be controlled by a user option.
14610 (push_it, pop_it): Save and restore the state of the
14611 bidi iterator. Save and restore the bidi_p flag.
14612 (pop_it): Iterate out of display property for string iteration as
14614 (iterate_out_of_display_property): Support iteration over strings.
14615 (handle_single_display_spec): Set up it->bidi_it for iteration
14616 over a display string, and call bidi_init_it.
14617 (handle_single_display_spec, next_overlay_string)
14618 (get_overlay_strings_1, push_display_prop): Set up the bidi
14619 iterator for displaying display or overlay strings.
14620 (forward_to_next_line_start): Don't use the shortcut if
14622 (back_to_previous_visible_line_start): If handle_display_prop
14623 pushed the iterator stack, restore the internal state of the bidi
14624 iterator by calling bidi_pop_it same number of times.
14625 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
14626 and we are bidi-iterating, don't decrement the iterator position;
14627 instead, set the first_elt flag in the bidi iterator, to produce
14629 (reseat_1): Remove redundant setting of string_from_display_prop_p.
14630 (push_display_prop): xassert that we are iterating a buffer.
14631 (push_it, pop_it): Save and restore paragraph_embedding member.
14632 (handle_single_display_spec, next_overlay_string)
14633 (get_overlay_strings_1, reseat_1, reseat_to_string)
14634 (push_display_prop): Set up the `unibyte' member of bidi_it.string
14635 correctly. Don't assume unibyte strings are not bidi-reordered.
14636 (compute_display_string_pos)
14637 (compute_display_string_end): Fix handling the case of C string.
14638 (push_it, pop_it): Save and restore from_disp_prop_p.

14643 popping after iteration over a string that came from a display
14644 property. Fix a typo in popping stretch info. Add an assertion
14645 for verifying that the iterator position is in sync with the bidi
14647 (handle_single_display_spec, get_overlay_strings_1)
14648 (push_display_prop): Fix initialization of paragraph direction for
14649 string when that of the parent object is not yet determined.
14650 (reseat_1): Call bidi_init_it to resync the bidi
14651 iterator with IT's position. (Bug#7616)
14652 (find_row_edges): If ROW->start.pos gives position
14653 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
14654 (handle_stop, back_to_previous_visible_line_start, reseat_1):
14655 Reset the from_disp_prop_p flag.
14656 (SAVE_IT, RESTORE_IT): New macros.

14660 (move_it_to, move_it_vertically_backward, move_it_by_lines)
14661 (try_scrolling, redisplay_window, display_line): Use them when
14662 saving a temporary copy of the iterator and restoring it back.
14663 (back_to_previous_visible_line_start, reseat_1)
14664 (init_iterator): Empty the bidi cache "stack".
14665 (move_it_in_display_line_to): If iterator ended up at
14666 EOL, but we never saw any buffer positions smaller than
14667 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
14668 motion in bidi-reordered lines.
14669 (move_it_in_display_line_to): Record prev_method and prev_pos
14670 immediately before the call to set_iterator_to_next. Fixes cursor
14671 motion in bidi-reordered lines with stretch glyphs and strings
14672 displayed in margins. (Bug#8133) (Bug#8867)
14673 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
14675 (pos_visible_p): Support positions in bidi-reordered lines.
14676 Save and restore bidi cache.
14678 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
14679 (bidi_paragraph_info): Delete unused struct.
14680 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
14681 (bidi_cache_start): New variable.
14682 (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not

14690 (bidi_fetch_char): Accept new argument STRING; all callers
14691 changed. Support iteration over a string. Support strings with
14692 display properties. Support unibyte strings. Fix the type of
14693 `len' according to what STRING_CHAR_AND_LENGTH expects.
14694 (bidi_paragraph_init, bidi_resolve_explicit_1)
14695 (bidi_resolve_explicit, bidi_resolve_weak)
14696 (bidi_level_of_next_char, bidi_move_to_visually_next):
14697 Support iteration over a string.
14698 (bidi_set_sor_type, bidi_resolve_explicit_1)
14699 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
14700 can now be zero (for strings); special values 0 and -1 were
14701 changed to -1 and -2, respectively.
14702 (bidi_char_at_pos): New function.
14703 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):
14704 Call it instead of FETCH_MULTIBYTE_CHAR.

14714 (bidi_initialize): Initialize the bidi cache start stack pointer.
14715 (bidi_cache_ensure_space): New function, refactored from part of

14719 (bidi_count_bytes, bidi_char_at_pos): New functions.
14720 (bidi_cache_search): Don't assume bidi_cache_last_idx is

14789 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
14791 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
14792 The old code sometimes used this field without initializing it.
14794 * alloc.c (gc_sweep): Don't read past end of array.
14795 In theory, the old code could also have corrupted Emacs internals,
14796 though it'd be very unlikely.

15062 if Emacs is configured with --with-wide-int.
15063 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):

15100 Random fixes. E.g., (random) never returned negative values.
15101 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
15102 subseconds part to the entropy, as that's a bit more random.
15103 Prefer signed to unsigned, since the signedness doesn't matter and
15104 in general we prefer signed. When given a limit, use a
15105 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
15106 latter isn't right if USE_2_TAGS_FOR_INTS.
15107 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
15108 not 0..VALMASK. Don't discard "excess" bits that random () returns.

15118 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
15120 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
15121 This is more efficient than Ffile_directory_p and avoids a minor race.
15123 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
15125 * buffer.c (Foverlay_put): Say what the return value is
15128 * fileio.c (barf_or_query_if_file_exists): Check first if the file
15129 is a directory before asking whether to use the file name
15131 (barf_or_query_if_file_exists): Make the "File is a directory"
15132 error be more correct.
15134 * fns.c (Frequire): Remove the mention of the .gz files, since
15135 that's installation-specific, but keep the mention of
15136 `get-load-suffixes'.

15140 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

15146 (syms_of_gnutls): Remove duplicate DEFSYM for
15147 Qgnutls_bootprop_verify_hostname_error, an error for
15148 Qgnutls_bootprop_verify_error (which is no longer used).
15150 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
15151 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
15152 Also (re)move comments that are misplaced or no longer relevant.
15154 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15156 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

15253 * eval.c (struct backtrace): Simplify and port the data structure.
15254 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
15255 signed bit field, as this assumption is not portable and it makes
15256 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
15257 "char debug_on_exit : 1" as this is not portable either; instead,
15258 use the portable "unsigned int debug_on_exit : 1". Remove unused
15259 member evalargs. Remove obsolete comments about cc bombing out.

15333 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
15334 and use min_width/height from frames size_hint to set
15335 min_width/height (Bug#8919).

15449 (read1): Check for integer overflow in radices, and in
15450 read-circle numbers.

15494 on undefined behavior with wrong number of arguments.
15495 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
15496 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
15497 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
15498 since we're not interested in debugging glyphs with old libraries.
15499 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
15500 GCC 4.6.0's static checking.

15542 (x_session_initialize): Do not assume string length fits in int.
15544 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
15545 This is unlikely, but can occur if DPI is outlandish.
15547 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):

15590 Don't assume pid_t and time_t fit in unsigned long.
15591 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
15592 (current_lock_owner): Prefer signed type for sizes.
15593 Use memcpy, not strncpy, where memcpy is what is really wanted.
15594 Don't assume (via atoi) that time_t and pid_t fit in int.
15595 Check for time_t and/or pid_t out of range, e.g., via a network share.
15596 Don't alloca where an auto var works fine.

15612 We prefer signed integers, even for size calculations.
15614 * emacs.c: Don't assume string length fits in 'int'.
15615 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
15616 (main): Don't invoke strlen when not needed.
15618 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
15619 (XD_DEBUG_MESSAGE): Don't waste a byte.
15621 * callproc.c (getenv_internal_1, getenv_internal)
15622 (Fgetenv_internal):
15623 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
15625 * lread.c (invalid_syntax): Omit length argument.
15626 All uses changed. This doesn't fix a bug, but it simplifies the
15627 code away from its former Hollerith-constant appearance, and it's
15628 one less 'int' to worry about when looking at integer-overflow issues.
15629 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
15631 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
15632 This didn't break anything, but it didn't help either.
15633 It's confusing to put a bogus integer in a place where the actual
15634 value does not matter.
15635 (LIST_END_P): Remove unused macro and its bogus comment.
15636 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
15638 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
15639 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
15641 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
15642 We prefer signed types, and the value cannot exceed the EMACS_INT
15643 range anyway (because otherwise the length would not be representable).
15644 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
15645 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
15646 This avoids a GCC warning when WIDE_EMACS_INT.
15648 * indent.c (sane_tab_width): New function.
15649 (current_column, scan_for_column, Findent_to, position_indentation)
15650 (compute_motion): Use it. This is just for clarity.
15651 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
15653 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
15655 * lisp.h (lint_assume): New macro.
15656 * composite.c (composition_gstring_put_cache):
15657 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
15659 * editfns.c, insdel.c:
15660 Omit unnecessary forward decls, to simplify future changes.
15662 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
15664 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
15666 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
15667 Use much-faster test for byte-length change.
15668 Don't assume string byte-length fits in 'int'.
15669 Check that character arg fits in 'int'.
15670 (mapcar1): Declare byte as byte, for clarity.
15672 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
15674 * fns.c (concat): Catch string overflow earlier.
15675 Do not rely on integer wraparound.
15677 * dispextern.h (struct it.overlay_strings_charpos)
15678 (struct it.selective): Now EMACS_INT, not int.
15679 * xdisp.c (forward_to_next_line_start)
15680 (back_to_previous_visible_line_start)
15681 (reseat_at_next_visible_line_start, next_element_from_buffer):
15682 Don't arbitrarily truncate the value of 'selective' to int.
15684 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
15686 * composite.c: Don't truncate sizes to 'int'.
15687 (composition_gstring_p, composition_reseat_it)
15688 (composition_adjust_point): Use EMACS_INT, not int.
15689 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
15690 not EMACS_UINT, for indexes.
15692 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
15694 * buffer.c: Include <verify.h>.
15695 (struct sortvec.priority, struct sortstr.priority):
15696 Now EMACS_INT, not int.
15697 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
15698 (struct sortstr.size, record_overlay_string)
15699 (struct sortstrlist.size, struct sortlist.used):
15700 Don't truncate size to int.
15701 (record_overlay_string): Check for size-calculation overflow.
15702 (init_buffer_once): Check at compile-time, not run-time.
15704 2011-06-22 Jim Meyering <meyering@redhat.com>
15706 Don't leak an XBM-image-sized buffer
15707 * image.c (xbm_load): Free the image buffer after using it.
15709 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
15712 * composite.c (find_automatic_composition): Omit needless 'return 0;'
15713 that Sun C diagnosed.
15714 * fns.c (secure_hash): Fix pointer signedness issue.
15715 * intervals.c (static_offset_intervals): New function.
15716 (offset_intervals): Use it.
15718 2011-06-21 Leo Liu <sdl.web@gmail.com>
15721 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
15724 * fns.c (secure_hash): Rename from crypto_hash_function and change
15725 the first arg to accept symbols.
15726 (Fsecure_hash): New primitive.
15727 (syms_of_fns): New symbols.
15729 2011-06-20 Deniz Dogan <deniz@dogan.se>
15731 * process.c (Fset_process_buffer): Clarify return value in
15734 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
15736 * dispnew.c (add_window_display_history): Use BVAR.
15738 * xdisp.c (debug_method_add): Use BVAR.
15739 (check_window_end, dump_glyph_matrix, dump_glyph)
15740 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
15742 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
15745 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
15746 check till after the cache is created in init_frame_faces.
15748 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
15750 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
15752 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
15754 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
15755 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
15756 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
15758 Improve buffer-overflow checking (Bug#8873).
15759 * fileio.c (Finsert_file_contents):
15760 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
15761 Remove the old (too-loose) buffer overflow checks.
15762 They weren't needed, since make_gap checks for buffer overflow.
15763 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
15764 The old code merely checked for Emacs fixnum overflow, and relied
15765 on undefined (wraparound) behavior. The new code avoids undefined
15766 behavior, and also checks for ptrdiff_t and/or size_t overflow.
15768 * editfns.c (Finsert_char): Don't dump core with very negative counts.
15769 Tune. Don't use wider integers than needed. Don't use alloca.
15770 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
15772 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
15774 * insdel.c, lisp.h (buffer_overflow): New function.
15775 (insert_from_buffer_1, replace_range, replace_range_2):
15776 * insdel.c (make_gap_larger):
15777 * editfns.c (Finsert_char):
15778 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
15780 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
15782 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
15784 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
15786 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
15787 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
15789 * fileio.c: Don't assume EMACS_INT fits in off_t.
15790 (emacs_lseek): New static function.
15791 (Finsert_file_contents, Fwrite_region): Use it.
15792 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
15794 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
15796 * fns.c: Don't overflow int when computing a list length.
15797 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
15798 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
15799 truncation on 64-bit hosts. Check for QUIT every
15800 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
15801 faster and is responsive enough.
15802 (Flength): Report an error instead of overflowing an integer.
15803 (Fsafe_length): Return a float if the value is not representable
15804 as a fixnum. This shouldn't happen except in contrived situations.
15805 (Fnthcdr, Fsort): Don't assume list length fits in int.
15806 (Fcopy_sequence): Don't assume vector length fits in int.
15808 * alloc.c: Check that resized vectors' lengths fit in fixnums.
15809 (header_size, word_size): New constants.
15810 (allocate_vectorlike): Don't check size overflow here.
15811 (allocate_vector): Check it here instead, since this is the only
15812 caller of allocate_vectorlike that could cause overflow.
15813 Check that the new vector's length is representable as a fixnum.
15815 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
15816 The previous code was bogus. For example, next_almost_prime (32)
15817 returned 39, which is undesirable as it is a multiple of 3; and
15818 next_almost_prime (24) returned 25, which is a multiple of 5 so
15819 why was the code bothering to check for multiples of 7?
15821 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
15823 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
15825 Variadic C functions now count arguments with ptrdiff_t.
15826 This partly undoes my 2011-03-30 change, which replaced int with size_t.
15827 Back then I didn't know that the Emacs coding style prefers signed int.
15828 Also, in the meantime I found a few more instances where arguments
15829 were being counted with int, which may truncate counts on 64-bit
15830 machines, or EMACS_INT, which may be unnecessarily wide.
15831 * lisp.h (struct Lisp_Subr.function.aMANY)
15832 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
15833 Arg counts are now ptrdiff_t, not size_t.
15834 All variadic functions and their callers changed accordingly.
15835 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
15836 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
15837 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
15838 * callint.c (Fcall_interactively): Check arg count for overflow,
15839 to avoid potential buffer overrun. Use signed char, not 'int',
15840 for 'varies' array, so that we needn't bother to check its size
15841 calculation for overflow.
15842 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
15843 * eval.c (apply_lambda):
15844 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
15845 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
15846 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
15848 * callint.c (Fcall_interactively): Don't use index var as event count.
15850 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
15851 * mem-limits.h (SIZE): Remove; no longer used.
15853 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
15855 Remove unnecessary casts.
15856 * xterm.c (x_term_init):
15857 * xfns.c (x_set_border_pixel):
15858 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
15859 These aren't needed now that we assume ANSI C.
15861 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
15862 It's more likely to cause problems (due to unsigned overflow)
15865 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
15867 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
15869 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
15871 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
15873 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
15875 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
15877 GLYPH_CODE_FACE returns EMACS_INT, not int.
15878 * dispextern.h (merge_faces):
15879 * xfaces.c (merge_faces):
15880 * xdisp.c (get_next_display_element, next_element_from_display_vector):
15881 Don't assume EMACS_INT fits in int.
15883 * character.h (CHAR_VALID_P): Remove unused parameter.
15884 * fontset.c, lisp.h, xdisp.c: All uses changed.
15886 * editfns.c (Ftranslate_region_internal): Omit redundant test.
15888 * fns.c (concat): Minor tuning based on overflow analysis.
15889 This doesn't fix any bugs. Use int to hold character, instead
15890 of constantly refetching from Emacs object. Use XFASTINT, not
15891 XINT, for value known to be a character. Don't bother comparing
15892 a single byte to 0400, as it's always less.
15894 * floatfns.c (Fexpt):
15895 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
15897 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
15900 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
15902 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
15903 Without this fix, on a 64-bit host (aset S 0 4294967386) would
15904 incorrectly succeed when S was a string, because 4294967386 was
15905 truncated before it was used.
15907 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
15908 Otherwise, an out-of-range integer could cause undefined behavior
15911 * composite.c: Use int, not EMACS_INT, for characters.
15912 (fill_gstring_body, composition_compute_stop_pos): Use int, not
15913 EMACS_INT, for values that are known to be in character range.
15914 This doesn't fix any bugs but is the usual style inside Emacs and
15915 may generate better code on 32-bit machines.
15917 Make sure a 64-bit char is never passed to ENCODE_CHAR.
15918 This is for reasons similar to the recent CHAR_STRING fix.
15919 * charset.c (Fencode_char): Check that character arg is actually
15920 a character. Pass an int to ENCODE_CHAR.
15921 * charset.h (ENCODE_CHAR): Verify that the character argument is no
15922 wider than 'int', as a compile-time check to prevent future regressions
15925 * character.c (char_string): Remove unnecessary casts.
15927 Make sure a 64-bit char is never passed to CHAR_STRING.
15928 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
15929 by silently ignoring the top 32 bits, allowing some values
15930 that were far too large to be valid characters.
15931 * character.h: Include <verify.h>.
15932 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
15933 arguments are no wider than unsigned, as a compile-time check
15934 to prevent future regressions in this area.
15936 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
15937 (Fsubst_char_in_region):
15939 * xdisp.c (decode_mode_spec_coding):
15940 Adjust to CHAR_STRING's new requirement.
15941 * editfns.c (Finsert_char, Fsubst_char_in_region):
15942 * fns.c (concat): Check that character args are actually
15943 characters. Without this test, these functions did the wrong
15944 thing with wildly out-of-range values on 64-bit hosts.
15946 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
15947 These casts should not be needed on 32-bit hosts, either.
15948 * keyboard.c (read_char):
15949 * lread.c (Fload): Remove casts to unsigned.
15951 * lisp.h (UNSIGNED_CMP): New macro.
15952 This fixes comparison bugs on 64-bit hosts.
15953 (ASCII_CHAR_P): Use it.
15954 * casefiddle.c (casify_object):
15955 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
15956 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
15957 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
15958 * dispextern.h (FACE_FROM_ID):
15959 * keyboard.c (read_char): Use UNSIGNED_CMP.
15961 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
15962 not to EMACS_INT, to avoid GCC warning.
15964 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
15966 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
15967 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
15968 isn't needed on 32-bit machines.
15970 * buffer.c (Fgenerate_new_buffer_name):
15971 Use EMACS_INT for count, not int.
15972 (advance_to_char_boundary): Return EMACS_INT, not int.
15974 * data.c (Qcompiled_function): Now static.
15976 * window.c (window_body_lines): Now static.
15978 * image.c (gif_load): Rename local to avoid shadowing.
15980 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
15981 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
15982 * alloc.c (make_save_value): Integer argument is now of type
15983 ptrdiff_t, not int.
15984 (mark_object): Use ptrdiff_t, not int.
15985 * lisp.h (pD): New macro.
15986 * print.c (print_object): Use it.
15988 * alloc.c: Use EMACS_INT, not int, to count objects.
15989 (total_conses, total_markers, total_symbols, total_vector_size)
15990 (total_free_conses, total_free_markers, total_free_symbols)
15991 (total_free_floats, total_floats, total_free_intervals)
15992 (total_intervals, total_strings, total_free_strings):
15993 Now EMACS_INT, not int. All uses changed.
15994 (Fgarbage_collect): Compute overall total using a double, so that
15995 integer overflow is less likely to be a problem. Check for overflow
15996 when converting back to an integer.
15997 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
15998 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
15999 These were 'int' variables that could overflow on 64-bit hosts;
16000 they were never used, so remove them instead of repairing them.
16001 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
16002 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
16003 Previously, this ceilinged at INT_MAX, but that doesn't work on
16005 (allocate_pseudovector): Don't use EMACS_INT when int would do.
16007 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
16008 (allocate_vectorlike): Check for ptrdiff_t overflow.
16009 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
16010 when a (possibly-narrower) signed value would do just as well.
16011 We prefer using signed arithmetic, to avoid comparison confusion.
16013 * alloc.c: Catch some string size overflows that we were missing.
16014 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
16015 for convenience in STRING_BYTES_MAX.
16016 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
16017 The definition here is exact; the one in lisp.h was approximate.
16018 (allocate_string_data): Check for string overflow. This catches
16019 some instances we weren't catching before. Also, it catches
16020 size_t overflow on (unusual) hosts where SIZE_MAX <= min
16021 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
16022 and ptrdiff_t and EMACS_INT are both 64 bits.
16024 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
16025 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
16026 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
16028 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
16030 * alloc.c (Fmake_string): Check for out-of-range init.
16032 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
16034 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
16036 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
16038 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
16039 xg_get_default_scrollbar_width.
16041 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
16042 (int_gtk_range_get_value): Move to the scroll bar part of the file.
16043 (style_changed_cb): Call update_theme_scrollbar_width and call
16044 x_set_scroll_bar_default_width and xg_frame_set_char_size for
16045 all frames (Bug#8505).
16046 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
16047 Call gtk_window_set_resizable if HAVE_GTK3.
16048 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
16049 and height if HAVE_GTK3 (Bug#8505).

16496 Fframe_first_window and Fset_frame_selected_window to window.h.
16498 * window.h: Move EXFUNS for Fframe_root_window,

16522 (Fwindow_minibuffer_p): Move up in code and simplify.
16523 (Fset_frame_selected_window): Move here from frame.c.
16525 (Fselected_window, select_window, Fselect_window): Move up in
16526 code. Minor doc-string fixes.
16528 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
16530 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
16531 Do not assume that spare memory exists; that assumption is valid
16532 only if SYSTEM_MALLOC.
16533 (LARGE_REQUEST): New macro, so that the issue of large requests
16534 is separated from the issue of spare memory.
16536 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>

16564 New error handlers.
16565 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
16566 Obey Vx_select_enable_clipboard_manager. Catch errors in
16567 x_clipboard_manager_save (Bug#8779).
16568 (Vx_select_enable_clipboard_manager): New variable.
16569 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
16571 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
16573 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
16575 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16577 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap

16584 2011-06-03 Eli Zaretskii <eliz@gnu.org>
16586 Support bidi reordering of text covered by display properties.
16588 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
16589 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
16590 (bidi_cache_search, bidi_cache_iterator_state)
16591 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
16592 (bidi_level_of_next_char, bidi_move_to_visually_next):
16593 Support character positions inside a run of characters covered by a
16595 (bidi_paragraph_init, bidi_resolve_explicit_1)
16596 (bidi_level_of_next_char): Call bidi_fetch_char and
16597 bidi_fetch_char_advance instead of FETCH_CHAR and
16598 FETCH_CHAR_ADVANCE.
16599 (bidi_init_it): Initialize new members.
16600 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
16602 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
16603 instead of using explicit *_CHAR codes.
16604 (bidi_resolve_explicit, bidi_resolve_weak):
16605 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
16606 bidirectional text is supported only in multibyte buffers.
16607 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
16608 it to initialize the frame_window_p member of struct bidi_it.
16609 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
16610 (bidi_resolve_explicit, bidi_resolve_weak)

16612 bidi_it->nchars is non-positive.
16613 (bidi_level_of_next_char): Don't try to lookup the cache for the
16614 next/previous character if nothing is cached there yet, or if we
16615 were just reseat()'ed to a new position.
16617 * xdisp.c (set_cursor_from_row): Set start and stop points
16618 according to the row's direction when priming the loop that looks
16619 for the glyph on which to display cursor.
16620 (single_display_spec_intangible_p): Function deleted.
16621 (display_prop_intangible_p): Reimplement to call
16622 handle_display_spec instead of single_display_spec_intangible_p.
16623 Accept 3 additional arguments needed by handle_display_spec.
16624 This fixes incorrect cursor motion across display property with complex
16625 values: lists, `(when COND...)' forms, etc.
16626 (single_display_spec_string_p): Support property values that are
16627 lists with the argument STRING its top-level element.
16628 (display_prop_string_p): Fix the condition for processing a
16629 property that is a list to be consistent with handle_display_spec.
16630 (handle_display_spec): New function, refactored from the
16631 last portion of handle_display_prop.
16632 (compute_display_string_pos): Accept additional argument
16633 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
16634 value of a `display' property is a "replacing spec".
16635 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
16636 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
16637 the display property, but just return a value indicating whether
16638 the display property will replace the characters it covers.
16639 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
16640 frame_window_p members of struct bidi_it.
16641 (compute_display_string_pos, compute_display_string_end):
16643 (push_it): Accept second argument POSITION, where pop_it should
16644 jump to continue iteration.
16645 (reseat_1): Initialize bidi_it.disp_pos.
16647 * keyboard.c (adjust_point_for_property): Adjust the call to
16648 display_prop_intangible_p to its new signature.
16650 * dispextern.h (struct bidi_it): New member frame_window_p.
16651 (bidi_init_it): Update prototypes.
16652 (display_prop_intangible_p): Update prototype.
16653 (compute_display_string_pos, compute_display_string_end):
16654 Declare prototypes.
16655 (struct bidi_it): New members nchars and disp_pos. ch_len is now
16658 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
16660 Malloc failure behavior now depends on size of allocation.
16661 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
16662 * lisp.h: Change signatures accordingly.
16663 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
16664 All callers changed. (Bug#8762)
16666 * gnutls.c: Use Emacs's memory allocators.
16667 Without this change, the gnutls library would invoke malloc etc.
16668 directly, which causes problems on non-SYNC_INPUT hosts, and which
16669 runs afoul of improving memory_full behavior. (Bug#8761)
16670 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
16671 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
16672 xfree instead of the default malloc, realloc, free.
16673 (Fgnutls_boot): No need to check for memory allocation failure,
16674 since xmalloc does that for us.
16676 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
16677 * category.c (hash_get_category_set):
16678 * ccl.c (ccl_driver):
16679 * charset.c (Fdefine_charset_internal):
16680 * charset.h (struct charset.hash_index):

16682 (composition_gstring_put_cache):
16683 * composite.h (struct composition.hash_index):
16684 * dispextern.h (struct image.hash):

16690 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
16691 (Fsxhash, Fgethash, Fputhash, Fmaphash):
16692 * image.c (make_image, search_image_cache, lookup_image)
16693 (xpm_put_color_table_h):
16694 * lisp.h (struct Lisp_Hash_Table):
16695 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
16696 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
16697 for hashes and hash indexes, instead of 'unsigned' and 'int'.
16698 * alloc.c (allocate_vectorlike):
16699 Check for overflow in vector size calculations.
16700 * ccl.c (ccl_driver):
16701 Check for overflow when converting EMACS_INT to int.
16702 * fns.c, image.c: Remove unnecessary static decls that would otherwise
16703 need to be updated by these changes.
16704 * fns.c (make_hash_table, maybe_resize_hash_table):
16705 Check for integer overflow with large hash tables.
16706 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
16707 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
16708 (SXHASH_REDUCE): New macro.
16709 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
16710 Use it instead of discarding useful hash info with large hash values.
16711 (sxhash_float): New function.
16712 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
16713 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
16714 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
16715 Rewrite to use FIXNUM_BITS, as this simplifies things.
16716 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
16717 Adjust signatures to match updated version of code.
16718 (consing_since_gc): Now EMACS_INT, since a single hash table can
16719 use more than INT_MAX bytes.
16721 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
16723 Make it possible to build with GCC-4.6+ -O2 -flto.
16725 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
16727 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
16729 * minibuf.c (get_minibuffer, read_minibuf_unwind):
16730 Call minibuffer-inactive-mode.
16732 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
16734 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
16735 Update dependencies.
16737 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
16739 * data.c (init_data): Remove code for UTS, this system is not
16742 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
16744 Don't force ./temacs to start in terminal mode.
16746 * frame.c (make_initial_frame): Initialize faces in all cases, not
16747 only when CANNOT_DUMP is defined.
16748 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
16750 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
16752 * dispnew.c (add_window_display_history): Use const for the string
16753 pointer. Remove declaration, not needed.
16755 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
16757 Use 'inline', not 'INLINE'.
16758 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
16759 * alloc.c, fontset.c (INLINE): Remove.
16760 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
16761 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
16762 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
16763 * gmalloc.c (register_heapinfo): Use inline unconditionally.
16764 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
16766 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
16768 Make it possible to run ./temacs.
16770 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
16771 syms_of_callproc does the same thing. Remove test for
16772 "initialized", do it in the caller.
16773 * emacs.c (main): Avoid calling set_initial_environment when dumping.
16775 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
16777 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
16778 (read_minibuf): Use get_minibuffer.
16779 (syms_of_minibuf): Use DEFSYM.
16780 (Qmetadata): New var.
16781 * data.c (Qbuffer): Don't make it static.
16782 (syms_of_data): Use DEFSYM.
16784 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
16786 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
16787 (CCL_CODE_MIN): New macro.
16789 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
16791 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
16793 * eval.c (Qdebug): Now static.
16794 * lisp.h (Qdebug): Remove decl. This reverts a part of the
16795 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
16796 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
16798 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
16800 * image.c: Various fixes to ImageMagick code comments.
16801 (Fimagemagick_types): Doc fix.
16803 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
16805 Minor fixes prompted by GCC 4.6.0 warnings.
16807 * xselect.c (converted_selections, conversion_fail_tag): Now static.
16809 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
16810 (x_clipboard_manager_save_all): Move extern decl to ...
16811 * xterm.h: ... here, so that it can be checked for consistency.
16813 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
16815 * xselect.c (x_clipboard_manager_save_frame)
16816 (x_clipboard_manager_save_all): New functions.
16817 (Fx_clipboard_manager_save): Lisp function deleted.
16819 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
16820 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
16822 * xterm.h: Update prototype.
16824 2011-05-28 William Xu <william.xwl@gmail.com>
16826 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
16827 exiting (Bug#8239).
16829 2011-05-28 Jim Meyering <meyering@redhat.com>
16831 Avoid a sign-extension bug in crypto_hash_function.
16832 * fns.c (to_uchar): Define.
16833 (crypto_hash_function): Use it to convert some newly-signed
16834 variables to unsigned, to avoid sign-extension bugs. For example,
16835 without this change, (md5 "truc") would evaluate to
16836 45723a2aff78ff4fff7fff1114760e62 rather than the expected
16837 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
16838 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
16840 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
16842 Integer overflow fixes.
16844 * dbusbind.c: Serial number integer overflow fixes.
16845 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
16846 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
16847 to hold a serial number that is too large for a fixnum.
16848 (Fdbus_method_return_internal, Fdbus_method_error_internal):
16849 Check for serial numbers out of range. Decode any serial number
16850 that was so large that it became a float. (Bug#8722)
16852 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
16853 (Fdbus_call_method, Fdbus_call_method_asynchronously):
16854 Use XFASTINT rather than XUINT when numbers are nonnegative.
16855 (xd_append_arg, Fdbus_method_return_internal):
16856 (Fdbus_method_error_internal): Likewise. Also, for unsigned
16857 arguments, check that Lisp number is nonnegative, rather than
16858 silently wrapping negative numbers around. (Bug#8722)
16859 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
16862 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
16864 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
16866 ccl: Add integer overflow checks.
16867 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
16868 (IN_INT_RANGE): New macros.
16869 (ccl_driver): Use them to check for integer overflow when
16870 decoding a CCL program. Many of the new checks are whether XINT (x)
16871 fits in int; it doesn't always, on 64-bit hosts. The new version
16872 doesn't catch all possible integer overflows, but it's an
16873 improvement. (Bug#8719)
16875 * alloc.c (make_event_array): Use XINT, not XUINT.
16876 There's no need for unsigned here.
16878 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
16879 This follows up to the 2011-05-06 change that substituted uintptr_t
16880 for EMACS_INT. This case wasn't caught back then.
16882 Rework Fformat to avoid integer overflow issues.
16883 * editfns.c: Include <float.h> unconditionally, as it's everywhere
16884 now (part of C89). Include <verify.h>.
16885 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
16886 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
16887 (Fformat): Avoid the prepass trying to compute sizes; it was only
16888 approximate and thus did not catch overflow reliably. Instead, walk
16889 through the format just once, formatting and computing sizes as we go,
16890 checking for integer overflow at every step, and allocating a larger
16891 buffer as needed. Keep track separately whether the format is
16892 multibyte. Keep only the most-recently calculated precision, rather
16893 than them all. Record whether each argument has been converted to
16894 string. Use EMACS_INT, not int, for byte and char and arg counts.
16895 Support field widths and precisions larger than INT_MAX. Avoid
16896 sprintf's undefined behavior with conversion specifications such as %#d
16897 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
16898 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
16899 formatting out-of-range floating point numbers with int
16900 formats. (Bug#8668)
16902 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
16904 * data.c: Avoid integer truncation in expressions involving floats.
16905 * data.c: Include <intprops.h>.
16906 (arith_driver): When there's an integer overflow in an expression
16907 involving floating point, convert the integers to floating point
16908 so that the resulting value does not suffer from catastrophic
16909 integer truncation. For example, on a 64-bit host (* 4
16910 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
16911 Do not rely on undefined behavior after integer overflow.
16913 merge count_size_as_multibyte, parse_str_to_multibyte
16914 * character.c, character.h (count_size_as_multibyte):
16915 Rename from parse_str_to_multibyte; all uses changed.
16916 Check for integer overflow.
16917 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
16918 since it's now a duplicate of the other. This is more of
16919 a character than a buffer op, so better that it's in character.c.
16920 * fns.c, print.c: Adjust to above changes.
16922 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
16924 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
16926 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
16928 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
16929 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
16930 (x_clipboard_manager_save): Now static.
16931 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
16933 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
16934 (crypto_hash_function): Now static.
16935 Fix pointer signedness problems. Avoid unnecessary initializations.
16937 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
16939 * termhooks.h (Vselection_alist): Make it terminal-local.
16941 * terminal.c (create_terminal): Initialize it.
16943 * xselect.c: Support for clipboard managers.
16944 (Vselection_alist): Move to termhooks.h as terminal-local var.
16945 (LOCAL_SELECTION): New macro.
16946 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
16947 (symbol_to_x_atom): Remove gratuitous arg.
16948 (x_handle_selection_request, lisp_data_to_selection_data)
16949 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
16950 (x_own_selection, x_get_local_selection, x_convert_selection):
16951 New arg, specifying work frame. Use terminal-local Vselection_alist.
16952 (some_frame_on_display): Delete unused function.
16953 (Fx_own_selection_internal, Fx_get_selection_internal)
16954 (Fx_disown_selection_internal, Fx_selection_owner_p)
16955 (Fx_selection_exists_p): New optional frame arg.
16956 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
16957 (x_handle_selection_clear): Don't treat other terminals with the
16958 same keyboard specially. Use the terminal-local Vselection_alist.
16959 (x_clear_frame_selections): Use Frun_hook_with_args.
16961 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
16963 * xterm.h: Add support for those atoms.
16965 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
16967 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
16968 (converted_selections, conversion_fail_tag): New global variables.
16969 (x_selection_request_lisp_error): Free the above.
16970 (x_get_local_selection): Remove unnecessary code.
16971 (x_reply_selection_request): Args changed; handle arbitrary array
16972 of converted selections stored in converted_selections.
16973 Separate the XChangeProperty and SelectionNotify steps.
16974 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
16975 (x_convert_selection): New function.
16976 (x_handle_selection_event): Simplify.
16977 (x_get_foreign_selection): Don't ignore incoming requests while
16978 waiting for an answer; this will fail when we implement
16979 SAVE_TARGETS, and seems unnecessary anyway.
16980 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
16981 (Vx_sent_selection_functions): Doc fix.
16983 2011-05-26 Leo Liu <sdl.web@gmail.com>
16985 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
16987 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16989 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
16991 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
16992 for fringe update if it has periodic bitmap.
16993 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
16994 and fringe_bitmap_periodic_p.
16996 * fringe.c (get_fringe_bitmap_data): New function.
16997 (draw_fringe_bitmap_1, update_window_fringes): Use it.
16998 (update_window_fringes): Record periodicity of fringe bitmap in glyph
16999 row. Mark glyph row for fringe update if periodicity changed.
17001 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
17002 for fringe update unless it has periodic bitmap.
17004 2011-05-25 Kenichi Handa <handa@m17n.org>
17006 * xdisp.c (get_next_display_element): Set correct it->face_id for
17007 a static composition.
17009 2011-05-24 Leo Liu <sdl.web@gmail.com>
17012 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
17014 * fns.c (crypto_hash_function, Fsha1): New function.
17015 (Fmd5): Use crypto_hash_function.
17016 (syms_of_fns): Add Ssha1.
17018 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
17020 * gnutls.c: Remove unused macros.
17021 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
17022 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
17023 Remove macros that are defined and never used.
17024 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
17026 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17028 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
17029 (Fx_get_selection_internal): Minor cleanup.
17030 (Fx_own_selection_internal): Rename arguments for consistency with
17033 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
17035 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
17037 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17039 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
17041 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17043 * dispnew.c (scrolling_window): Don't exclude the case that the
17044 last enabled row in the desired matrix touches the bottom boundary.
17046 2011-05-21 Glenn Morris <rgm@gnu.org>
17048 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
17049 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
17050 and add some more files.
17052 2011-05-20 Eli Zaretskii <eliz@gnu.org>
17054 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
17055 report_file_error introduced by the change from 2011-05-07.
17057 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
17059 * systime.h (Time): Define only if emacs is defined.
17060 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
17061 where the include path doesn't have X11/X.h by default. See
17062 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
17064 2011-05-20 Kenichi Handa <handa@m17n.org>
17066 * composite.c (find_automatic_composition): Fix previous change.
17068 2011-05-20 Glenn Morris <rgm@gnu.org>
17070 * lisp.mk: New file, split from Makefile.in.
17071 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
17072 (shortlisp): Remove.
17073 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
17075 2011-05-19 Glenn Morris <rgm@gnu.org>
17077 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
17078 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
17079 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
17080 (lisp): Set the order to that of loadup.el.
17081 (shortlisp): Make it a copy of $lisp.
17082 (SOME_MACHINE_LISP): Remove.
17083 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
17084 Use just $shortlisp, not $SOME_MACHINE_LISP too.
17086 2011-05-18 Kenichi Handa <handa@m17n.org>
17088 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
17089 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
17090 (find_automatic_composition): Mostly rewrite for efficiency.
17092 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
17094 * makefile.w32-in: Update dependencies.
17096 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
17098 * menu.c: Include limits.h (fixes the MS-Windows build broken by
17099 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
17101 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
17103 Fix some integer overflow issues, such as string length overflow.
17105 * insdel.c (count_size_as_multibyte): Check for string overflow.
17107 * character.c (lisp_string_width): Check for string overflow.
17108 Use EMACS_INT, not int, for string indexes and lengths; in
17109 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
17110 the resulting string length overflows an EMACS_INT; instead,
17111 report a string overflow if no precision given. When checking for
17112 precision exhaustion, use a check that cannot possibly have
17113 integer overflow. (Bug#8675)
17114 * character.h (lisp_string_width): Adjust to new signature.
17116 * alloc.c (string_overflow): New function.
17117 (Fmake_string): Use it. This doesn't change behavior, but saves
17118 a few bytes and will simplify future changes.
17119 * character.c (string_escape_byte8): Likewise.
17120 * lisp.h (string_overflow): New decl.
17122 Fixups, following up to the user-interface timestamp change.
17123 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
17124 for UI timestamps, instead of unsigned long.
17125 * msdos.c (mouse_get_pos): Likewise.
17126 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
17127 * w32gui.h (Time): Define by including "systime.h" rather than by
17128 declaring it ourselves. (Bug#8664)
17130 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
17131 * image.c (clear_image_cache): Likewise.
17133 * term.c (term_mouse_position): Don't assume time_t wraparound.
17135 Be more systematic about user-interface timestamps.
17136 Before, the code sometimes used 'Time', sometimes 'unsigned long',
17137 and sometimes 'EMACS_UINT', to represent these timestamps.
17138 This change causes it to use 'Time' uniformly, as that's what X uses.
17139 This makes the code easier to follow, and makes it easier to catch
17140 integer overflow bugs such as Bug#8664.
17141 * frame.c (Fmouse_position, Fmouse_pixel_position):
17142 Use Time, not unsigned long, for user-interface timestamps.
17143 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
17144 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
17145 * keyboard.h (last_event_timestamp): Likewise.
17146 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
17147 * menu.h (xmenu_show): Likewise.
17148 * term.c (term_mouse_position): Likewise.
17149 * termhooks.h (struct input_event.timestamp): Likewise.
17150 (struct terminal.mouse_position_hook): Likewise.
17151 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
17152 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
17153 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
17154 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
17155 what it was before.
17156 * menu.h, termhooks.h: Include "systime.h", for Time.
17158 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
17159 Don't assume that the difference between two unsigned long values
17160 can fit into an integer. At this point, we know button_down_time
17161 <= event->timestamp, so the difference must be nonnegative, so
17162 there's no need to cast the result if double-click-time is
17163 nonnegative, as it should be; check that it's nonnegative, just in
17164 case. This bug is triggered when events are more than 2**31 ms
17165 apart (about 25 days). (Bug#8664)
17167 * xselect.c (last_event_timestamp): Remove duplicate decl.
17168 (x_own_selection): Remove needless cast to unsigned long.
17170 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
17171 that always fit in int. Use a sentinel instead of a counter, to
17172 avoid a temp and to allay GCC's concerns about possible int overflow.
17173 * frame.h (struct frame): Use int for menu_bar_items_used
17174 instead of EMACS_INT, since it always fits in int.
17176 * menu.c (grow_menu_items): Check for int overflow.
17178 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
17180 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
17181 Before, the code was not consistent. These values cannot exceed
17182 2**31 - 1 so there's no need to make them unsigned.
17183 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
17184 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
17185 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
17187 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
17189 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
17190 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
17191 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
17192 presumably because the widths might not match.
17194 * window.c (size_window): Avoid needless test at loop start.
17196 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
17198 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
17200 2011-05-12 Drew Adams <drew.adams@oracle.com>
17202 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
17204 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17206 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
17207 `width' to `bar_area_x' and `bar_area_width', respectively.
17208 (x_scroll_run): Take account of fringe background extension.
17210 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
17211 Rename local vars `left' and `width' to `bar_area_x' and
17212 `bar_area_width', respectively.
17213 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
17214 background extension.
17216 2011-05-10 Jim Meyering <meyering@redhat.com>
17218 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
17220 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
17222 * image.c (Finit_image_library): Return t for built-in image types,
17223 like pbm and xbm. (Bug#8640)
17225 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
17227 * w32menu.c (set_frame_menubar): Fix submenu allocation.
17229 2011-05-07 Eli Zaretskii <eliz@gnu.org>
17231 * w32console.c (Fset_screen_color): Doc fix.
17232 (Fget_screen_color): New function.
17233 (syms_of_ntterm): Defsubr it.
17235 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
17236 unlink the temporary file if Fcall_process didn't create it in the
17238 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
17239 child process will be redirected to a file specified with `:file'.
17240 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
17241 cue to call_process_cleanup not to close that handle.
17243 2011-05-07 Ben Key <bkey76@gmail.com>
17245 * makefile.w32-in: The bootstrap-temacs rule now makes use of
17246 one of two shell specific rules, either bootstrap-temacs-CMD or
17247 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
17248 to the previous implementation of the bootstrap-temacs rule.
17249 The bootstrap-temacs-CMD rule is similar to the previous
17250 implementation of the bootstrap-temacs rule except that it
17251 makes use of the ESC_CFLAGS variable instead of the CFLAGS
17254 These changes, along with some changes to nt/configure.bat,
17255 nt/gmake.defs, and nt/nmake.defs, are required to extend my
17256 earlier fix to add support for --cflags and --ldflags options
17257 that include quotes so that it works whether make uses cmd or
17260 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
17262 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
17263 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
17265 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
17266 a string. Handle both cases.
17267 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
17268 (Fdbus_register_method): Use Qinvalid_function.
17270 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
17272 * makefile.w32-in: Update dependencies.
17273 (LISP_H): Add inttypes.h and stdin.h.
17274 (PROCESS_H): Add unistd.h.
17276 2011-05-06 Eli Zaretskii <eliz@gnu.org>
17278 * lread.c: Include limits.h (fixes the MS-Windows build broken by
17279 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
17281 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
17283 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
17285 * term.c (vfatal): Remove stray call to va_end.
17286 It's not needed and the C Standard doesn't allow it here anyway.
17288 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
17289 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
17291 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
17294 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
17296 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
17298 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
17300 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
17302 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
17304 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
17305 * charset.c (Fdefine_charset_internal): Don't initialize
17306 charset.code_space[15]. The value was garbage, on hosts with
17307 32-bit int (Bug#8600).
17309 * lread.c (read_integer): Be more consistent with string-to-number.
17310 Use string_to_number to do the actual conversion; this avoids
17311 rounding errors and fixes some other screwups. Without this fix,
17312 for example, #x1fffffffffffffff was misread as -2305843009213693952.
17313 (digit_to_number): Move earlier, for benefit of read_integer.
17314 Return -1 if the digit is out of range for the base, -2 if it is
17315 not a digit in any supported base. (Bug#8602)
17317 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
17319 * dispnew.c (scrolling_window): Return 1 if we scrolled,
17320 to match comment at start of function. This also removes a
17321 GCC warning about overflow in a 32+64-bit port.
17323 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
17325 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
17326 Reported by Stefan Monnier in
17327 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
17328 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
17329 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
17331 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
17332 (EMACS_UINTPTR): Likewise, with uintptr_t.
17334 * lisp.h: Prefer 64-bit EMACS_INT if available.
17335 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
17336 on 32-bit hosts that have 64-bit int, so that they can access
17338 However, temporarily disable this change unless the temporary
17339 symbol WIDE_EMACS_INT is defined.
17341 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
17343 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
17344 This removes an assumption that EMACS_INT and long are the same
17345 width as pointers. The assumption is true for Emacs porting targets
17346 now, but we want to make other targets possible.
17347 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
17348 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
17349 In the rest of the code, change types of integers that hold casted
17350 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
17351 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
17352 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
17353 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
17354 No need to cast type when ORing.
17355 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
17356 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
17357 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
17358 assume EMACS_INT is the same width as char *.
17359 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
17360 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
17361 Remove no-longer-needed casts.
17362 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
17363 (xg_tool_bar_help_callback, xg_make_tool_item):
17364 Use EMACS_INTPTR to hold an integer
17365 that will be cast to void *; this can avoid a GCC warning
17366 if EMACS_INT is not the same width as void *.
17367 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
17368 * xdisp.c (display_echo_area_1, resize_mini_window_1):
17369 (current_message_1, set_message_1):
17370 Use a local to convert to proper width without a cast.
17371 * xmenu.c (dialog_selection_callback): Likewise.
17373 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
17374 Also, don't assume VALBITS / RAND_BITS is less than 5,
17375 and don't rely on undefined behavior when shifting a 1 left into
17377 * lisp.h (get_random): Change signature to match.
17379 * lread.c (hash_string): Use size_t, not int, for hash computation.
17380 Normally we prefer signed values; but hashing is special, because
17381 it's better to use unsigned division on hash table sizes so that
17382 the remainder is nonnegative. Also, size_t is the natural width
17383 for hashing into memory. The previous code used 'int', which doesn't
17384 retain enough info to hash well into very large tables.
17385 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
17387 * dbusbind.c: Don't possibly lose pointer info when converting.
17388 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
17389 Use XPNTR rather than XHASH, so that the high-order bits of
17390 the pointer aren't lost when converting through void *.
17392 * eval.c (Fautoload): Don't double-shift a pointer.
17394 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.

17428 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
17429 Remove unused parameter `fildes'.
17430 * process.c (read_process_output, send_process): Don't pass it.
17432 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
17434 Fix previous change: the library cache is defined in w32.c.
17435 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
17436 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".

17478 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
17479 instead of gnutls_record_check_pending.
17481 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
17483 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
17485 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
17486 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
17489 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
17491 * xterm.c (x_set_frame_alpha): Do not set property on anything

17526 (Fcall_process_region): Ditto.
17528 2011-04-30 Eli Zaretskii <eliz@gnu.org>
17530 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
17531 rather than `XVECTOR (FOO)->size'.
17533 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
17534 inttypes.h, as a gnulib replacement is used if it not available in
17537 2011-04-21 Eli Zaretskii <eliz@gnu.org>
17539 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
17540 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
17541 of MOST_POSITIVE_FIXNUM. (Bug#8528)
17543 * coding.c (coding_alloc_by_realloc): Error out if destination
17544 will grow beyond MOST_POSITIVE_FIXNUM.
17545 (decode_coding_emacs_mule): Abort if there isn't enough place in
17546 charbuf for the composition carryover bytes. Reserve an extra
17547 space for up to 2 characters produced in a loop.

17549 charbuf for the composition carryover bytes.
17551 2011-04-21 Eli Zaretskii <eliz@gnu.org>

17562 produced by %s or %c overflows available buffer space. (Bug#8545)
17564 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
17566 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

17599 2011-04-27 Eli Zaretskii <eliz@gnu.org>
17601 Improve `doprnt' and its usage. (Bug#8545)
17602 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
17603 `format_end'. Remove support for %l as a conversion specifier.
17604 Don't use xrealloc. Improve diagnostics when the %l size modifier
17605 is used. Update the commentary.
17607 * eval.c (verror): Simplify calculation of size_t.
17609 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
17612 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
17614 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
17617 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
17619 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
17620 This makes this file independent of the recent pseudovector change.
17622 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
17624 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
17626 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
17627 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
17628 Remove unused local.
17629 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
17631 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
17632 GCC 4.6.0 optimizes based on type-based alias analysis.
17633 For example, if b is of type struct buffer * and v of type struct
17634 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
17635 != &v->size, and therefore "v->size = 1; b->size = 2; return
17636 v->size;" must therefore return 1. This assumption is incorrect
17637 for Emacs, since it type-puns struct Lisp_Vector * with many other
17638 types. To fix this problem, this patch adds a new type struct
17639 vectorlike_header that documents the constraints on layout of vectors
17640 and pseudovectors, and helps optimizing compilers not get fooled
17641 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
17642 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
17643 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
17645 (XSETPVECTYPE): Rewrite in terms of new macro.
17646 (XSETPVECTYPESIZE): New macro, specifying both type and size.
17647 This is a bit clearer, and further avoids the possibility of
17648 undesirable aliasing.
17649 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
17650 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
17651 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
17652 since Lisp_Subr is a special case (no "next" field).
17653 (ASIZE): Now uses header.size rather than size.
17654 All previous uses of XVECTOR (foo)->size replaced to use this macro,
17655 to avoid the hassle of writing XVECTOR (foo)->header.size.
17656 (struct vectorlike_header): New type.
17657 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
17658 object, to help avoid aliasing.
17659 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
17660 (SUBRP): Likewise, since Lisp_Subr is a special case.
17661 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
17662 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
17663 (struct Lisp_Hash_Table): Combine first two members into a single
17664 struct vectorlike_header member. All uses of "size" and "next" members
17665 changed to be "header.size" and "header.next".
17666 * buffer.h (struct buffer): Likewise.
17667 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
17668 * frame.h (struct frame): Likewise.
17669 * process.h (struct Lisp_Process): Likewise.
17670 * termhooks.h (struct terminal): Likewise.
17671 * window.c (struct save_window_data, struct saved_window): Likewise.
17672 * window.h (struct window): Likewise.
17673 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
17674 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
17675 * buffer.c (init_buffer_once): Likewise.
17676 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
17678 * process.c (Fformat_network_address): Use local var for size,
17681 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
17683 Make the Lisp reader and string-to-float more consistent (Bug#8525)
17684 * data.c (atof): Remove decl; no longer used or needed.
17685 (digit_to_number): Move to lread.c.
17686 (Fstring_to_number): Use new string_to_number function, to be
17687 consistent with how the Lisp reader treats infinities and NaNs.
17688 Do not assume that floating-point numbers represent EMACS_INT
17689 without losing information; this is not true on most 64-bit hosts.
17690 Avoid double-rounding errors, by insisting on integers when
17691 parsing non-base-10 numbers, as the documentation specifies.
17692 * lisp.h (string_to_number): New decl, replacing ...
17693 (isfloat_string): Remove.
17694 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
17695 (read1): Do not accept +. and -. as integers; this
17696 appears to have been a coding error. Similarly, do not accept
17697 strings like +-1e0 as floating point numbers. Do not report
17698 overflow for integer overflows unless the base is not 10 which
17699 means we have no simple and reliable way to continue.
17700 Break out the floating-point parsing into a new
17701 function string_to_number, so that Fstring_to_number parses
17702 floating point numbers consistently with the Lisp reader.
17703 (digit_to_number): Move here from data.c. Make it static inline.
17704 (E_CHAR, EXP_INT): Remove, replacing with ...
17705 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
17706 (string_to_number): New function, replacing isfloat_string.
17707 This function checks for valid syntax and produces the resulting
17708 Lisp float number too. Rework it so that string-to-number
17709 no longer mishandles examples like "1.0e+". Use strtoumax,
17710 so that overflow for non-base-10 numbers is reported only when
17711 there's no portable and simple way to convert to floating point.
17713 * textprop.c (set_text_properties_1): Rewrite for clarity,
17714 and to avoid GCC warning about integer overflow.
17716 * intervals.h (struct interval): Use EMACS_INT for members
17717 where EMACS_UINT might cause problems. See
17718 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
17719 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
17720 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
17722 (offset_intervals): Tell GCC not to worry about length overflow
17723 when negating a negative length.
17725 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
17726 (overrun_check_free): Likewise.
17728 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
17729 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
17732 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
17733 (gnutls_make_error): Rename local to avoid shadowing.
17734 (gnutls_emacs_global_deinit): ifdef out; not used.
17735 (Fgnutls_boot): Use const for pointer to readonly storage.
17736 Comment out unused local. Fix pointer signedness problems.
17738 * lread.c (openp): Don't stuff size_t into an 'int'.
17739 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
17740 about possible signed overflow.
17742 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
17743 (GDK_KEY_g): Don't define if already defined.
17744 (xg_prepare_tooltip): Avoid pointer signedness problem.
17745 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
17747 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
17748 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
17750 * xfns.c (Fx_window_property): Simplify a bit,
17751 to make a bit faster and to avoid GCC 4.6.0 warning.
17752 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
17754 * fns.c (internal_equal): Don't assume size_t fits in int.
17756 * alloc.c (compact_small_strings): Tighten assertion a little.
17758 Replace pEd with more-general pI, and fix some printf arg casts.
17759 * lisp.h (pI): New macro, generalizing old pEd macro to other
17760 conversion specifiers. For example, use "...%"pI"d..." rather
17761 than "...%"pEd"...".
17762 (pEd): Remove. All uses replaced with similar uses of pI.
17763 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
17764 * alloc.c (check_pure_size): Don't overflow by converting size to int.
17765 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
17766 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
17767 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
17768 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
17769 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
17771 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
17772 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
17773 * print.c (safe_debug_print, print_object): Likewise.
17774 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
17776 Use pI instead of if-then-else-abort. Use %p to avoid casts,
17777 avoiding the 0 flag, which is not portable.
17778 * process.c (Fmake_network_process): Use pI to avoid cast.
17779 * region-cache.c (pp_cache): Likewise.
17780 * xdisp.c (decode_mode_spec): Likewise.
17781 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
17782 behavior on 64-bit hosts with printf arg.

17784 (x_stop_queuing_selection_requests): Likewise.
17785 (x_get_window_property): Don't truncate byte count to an 'int'
17788 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
17789 here, since it parses constructs like leading '-' and spaces,
17790 which are not wanted; and it overflows with large numbers.
17791 Instead, simply match F[0-9]+, which is what is wanted anyway.
17793 * alloc.c: Remove unportable assumptions about struct layout.
17794 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
17795 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
17796 (allocate_vectorlike, make_pure_vector): Use the new macros,
17797 plus offsetof, to remove unportable assumptions about struct layout.
17798 These assumptions hold on all porting targets that I know of, but
17799 they are not guaranteed, they're easy to remove, and removing them
17800 makes further changes easier.
17802 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
17803 This doesn't fix a bug but makes the code clearer.
17804 (string_overrun_cookie): Now const. Use initializers that
17805 don't formally overflow signed char, to avoid warnings.
17806 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
17807 can cause Emacs to crash when string overrun checking is enabled.
17808 (allocate_buffer): Don't assume sizeof (struct buffer) is a
17809 multiple of sizeof (EMACS_INT); it need not be, if
17810 alignof(EMACS_INT) < sizeof (EMACS_INT).
17811 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
17813 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

17840 2011-04-25 Eli Zaretskii <eliz@gnu.org>
17842 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
17843 "cast to pointer from integer of different size".
17845 Improve doprnt and its use in verror. (Bug#8545)
17846 * doprnt.c (doprnt): Document the set of format control sequences
17847 supported by the function. Use SAFE_ALLOCA instead of always
17850 * eval.c (verror): Don't limit the buffer size at size_max-1, that
17851 is one byte too soon. Don't use xrealloc; instead xfree and
17854 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
17856 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the

17860 gnutls_global_initialized. Added internals for the
17861 :verify-hostname-error, :verify-error, and :verify-flags
17862 parameters of `gnutls-boot' and documented those parameters in the
17863 docstring. Start callback support.
17864 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
17865 unless a fatal error occurred. Call gnutls_alert_send_appropriate

17926 changes in globals.h immediately force recompilation.
17927 (TAGS): Depend on $(CURDIR)/m/intel386.h and
17928 $(CURDIR)/s/ms-w32.h.

17963 * callint.c (Fcall_interactively): When displaying error message
17964 about invalid control letter, pass the character's codepoint, not

17969 codepoint of an invalid character, to avoid displaying a bogus
17972 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
17973 `error', not SYMBOL_NAME itself.
17975 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
17976 character arguments to `error'.
17978 * charset.c (check_iso_charset_parameter): Fix incorrect argument
17979 to `error' in error message about FINAL_CHAR argument. Make sure
17980 FINAL_CHAR is a character, and use %c when it is passed as
17981 argument to `error'.
17983 2011-04-23 Eli Zaretskii <eliz@gnu.org>
17985 * s/ms-w32.h (localtime): Redirect to sys_localtime.
17987 * w32.c: Include <time.h>.

18047 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
18048 by pacifying GCC about it. Maybe it's time to retire it?
18049 * xfaces.c (USG, __TIMEVAL__): Likewise.
18051 * dispextern.h (struct redisplay_interface): Rename param
18052 to avoid shadowing.
18053 * termhooks.h (struct terminal): Likewise.
18054 * xterm.c (xembed_send_message): Likewise.

18170 * nsfont.m: Fixed bugs in ns_get_family and
18171 ns_descriptor_to_entity that were caused by using free to
18172 deallocate memory blocks that were allocated by xmalloc (via
18173 xstrdup). This caused Emacs to crash when compiled with
18174 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
18175 --enable-checking=xmallocoverrun). xfree is now used to
18176 deallocate these memory blocks.

18190 (emacs_read, emacs_write): Remove check for negative size, as the
18191 Emacs source code has been audited now.
18192 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
18193 (emacs_read, emacs_write): Use it.
18194 * process.c (send_process): Adjust to the new signatures of
18195 emacs_write and emacs_gnutls_write. Do not attempt to store
18196 a byte offset into an 'int'; it might overflow.

18659 * alloc.c (overrun_check_malloc, overrun_check_realloc)
18660 (overrun_check_free): Protoize.
18662 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
18664 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
18665 since callers should never pass a negative size.
18666 Change the signature to match that of plain 'read' and 'write'; see
18667 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
18668 * lisp.h: Update prototypes of emacs_write and emacs_read.
18670 2011-04-11 Eli Zaretskii <eliz@gnu.org>
18672 * xdisp.c (redisplay_window): Don't try to determine the character
18673 position of the scroll margin if the window start point w->startp
18674 is outside the buffer's accessible region. (Bug#8468)
18676 2011-04-10 Eli Zaretskii <eliz@gnu.org>
18678 Fix write-region and its subroutines for buffers > 2GB.
18679 * fileio.c (a_write, e_write): Modify declaration of arguments and
18680 local variables to support buffers larger than 2GB.
18681 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
18683 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
18684 argument, local variables, and return value.
18686 * lisp.h: Update prototypes of emacs_write and emacs_read.
18688 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
18690 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
18692 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
18694 Fix more problems found by GCC 4.6.0's static checks.
18696 * xdisp.c (vmessage): Use a better test for character truncation.
18698 * charset.c (load_charset_map): <, not <=, for optimization,
18699 and to avoid potential problems with integer overflow.
18700 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
18701 * casetab.c (set_identity, shuffle): Likewise.
18702 * editfns.c (Fformat): Likewise.
18703 * syntax.c (skip_chars): Likewise.
18705 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
18706 This also lets GCC 4.6.0 generate slightly better loop code.
18708 * callint.c (Fcall_interactively): <, not <=, for optimization.
18709 (Fcall_interactively): Count the number of arguments produced,
18710 not the number of arguments given. This is simpler and lets GCC
18711 4.6.0 generate slightly better code.
18713 * ftfont.c: Distingish more carefully between FcChar8 and char.
18714 The previous code passed unsigned char * to a functions like
18715 strlen and xstrcasecmp that expect char *, which does not
18716 conform to the C standard.
18717 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
18718 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
18719 char * when the C standard requires it.
18721 * keyboard.c (read_char): Remove unused var.
18723 * eval.c: Port to Windows vsnprintf (Bug#8435).
18724 Include <limits.h>.
18725 (SIZE_MAX): Define if the headers do not.
18726 (verror): Do not give up if vsnprintf returns a negative count.
18727 Instead, grow the buffer. This ports to Windows vsnprintf, which
18728 does not conform to C99. Problem reported by Eli Zaretskii.
18729 Also, simplify the allocation scheme, by avoiding the need for
18730 calling realloc, and removing the ALLOCATED variable.
18732 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
18734 Remove invocations of doprnt, as Emacs now uses vsnprintf.
18735 But keep the doprint source code for now, as we might revamp it
18736 and use it again (Bug#8435).
18737 * lisp.h (doprnt): Remove.
18738 * Makefile.in (base_obj): Remove doprnt.o.
18739 * deps.mk (doprnt.o): Remove.
18741 error: Print 32- and 64-bit integers portably (Bug#8435).
18742 Without this change, on typical 64-bit hosts error ("...%d...", N)
18743 was used to print both 32- and 64-bit integers N, which relied on
18744 undefined behavior.
18745 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
18746 * lisp.h (error, verror): Mark as printf-like functions.
18747 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
18748 Report overflow in size calculations when allocating printf buffer.
18749 Do not truncate output string at its first null byte.
18750 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
18751 Truncate the output at a character boundary, since vsnprintf does not
18753 * charset.c (check_iso_charset_parameter): Convert internal
18754 character to string before calling 'error', since %c now has the
18756 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
18757 overflow when computing char to be passed to 'error'. Do not
18758 pass Lisp_Object to 'error'; pass the integer instead.
18759 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
18760 formatted with plain %d.
18762 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
18764 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
18766 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
18768 * xterm.c (x_catch_errors): Remove duplicate declaration.
18770 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
18772 * xdisp.c, lisp.h (message_nolog): Remove; unused.
18774 2011-04-10 Jim Meyering <meyering@redhat.com>
18776 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
18777 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
18778 return ssize_t not "int", and use size_t as the buffer length.
18779 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
18780 * gnutls.h: Update declarations.
18781 * process.c (read_process_output): Use ssize_t, to match.
18782 (send_process): Likewise.
18784 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
18786 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
18788 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
18790 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
18791 Use unsigned char, to match FcChar8 type definition.
18793 * xterm.c (handle_one_xevent):
18794 * xmenu.c (create_and_show_popup_menu):
18795 * xselect.c (x_decline_selection_request)
18796 (x_reply_selection_request): Avoid type-punned deref of X events.
18798 2011-04-09 Eli Zaretskii <eliz@gnu.org>
18800 Fix some uses of `int' instead of EMACS_INT.
18801 * search.c (string_match_1, fast_string_match)
18802 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
18803 (scan_buffer, find_next_newline_no_quit)
18804 (find_before_next_newline, search_command, Freplace_match)
18805 (Fmatch_data): Make some `int' variables be EMACS_INT.
18807 * xdisp.c (display_count_lines): 3rd argument and return value now
18808 EMACS_INT. All callers changed.
18809 (pint2hrstr): Last argument is now EMACS_INT.
18811 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
18812 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
18813 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
18814 (decode_coding_utf_16, decode_coding_emacs_mule)
18815 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
18816 (decode_coding_ccl, decode_coding_charset)
18817 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
18818 (decode_coding_iso_2022, decode_coding_emacs_mule)
18819 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
18820 <char_offset, last_offset>: Declare EMACS_INT.
18821 (encode_coding_utf_8, encode_coding_utf_16)
18822 (encode_coding_emacs_mule, encode_invocation_designation)
18823 (encode_designation_at_bol, encode_coding_iso_2022)
18824 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
18825 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
18827 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
18828 (encode_invocation_designation): Last argument P_NCHARS is now
18830 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
18831 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
18833 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
18836 * ccl.c (Fccl_execute_on_string): Declare some variables
18839 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
18841 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
18843 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
18845 * process.c (Fformat_network_address): Doc fix.
18847 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
18849 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
18851 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
18853 * keyboard.c (read_char): Call Lisp function help-form-show,
18854 instead of using internal_with_output_to_temp_buffer.
18855 (Qhelp_form_show): New var.
18856 (syms_of_keyboard): Use DEFSYM macro.
18858 * print.c (internal_with_output_to_temp_buffer): Function deleted.
18860 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
18862 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
18864 * process.c (Flist_processes): Remove to Lisp.
18865 (list_processes_1): Delete.
18867 2011-04-06 Eli Zaretskii <eliz@gnu.org>
18869 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
18871 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
18873 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
18875 Fix more problems found by GCC 4.6.0's static checks.
18877 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
18879 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
18881 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
18883 * xdisp.c (vmessage): Mark as a printf-like function.
18885 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
18887 * sound.c (sound_warning): Don't crash if arg contains a printf format.
18889 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
18890 printf-like functions.
18891 (tiff_load): Add casts to remove these marks before passing them
18892 to system-supplied API.
18894 * eval.c (Fsignal): Remove excess argument to 'fatal'.
18896 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
18897 This avoids several warnings with gcc -Wstrict-overflow.
18898 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
18899 directly, rather than having caller test rule sign. This avoids
18900 some unnecessary tests.
18901 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
18902 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
18903 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
18905 * xfont.c (xfont_text_extents): Remove var that was set but not used.
18906 (xfont_open): Avoid unnecessary tests.
18908 * composite.c (composition_gstring_put_cache): Use unsigned integer.
18910 * composite.h, composite.c (composition_gstring_put_cache):
18911 Use EMACS_INT, not int, for length.

18914 breaking out part of COMPOSITION_DECODE_RULE.
18915 (COMPOSITION_DECODE_RULE): Use it.
18916 * composite.c (get_composition_id): Remove unused local vars,
18917 by using the new macro.
18919 * textprop.c (set_text_properties_1): Change while to do-while,
18920 since the condition is always true at first.
18922 * intervals.c (graft_intervals_into_buffer): Mark var as used.
18923 (interval_deletion_adjustment): Return unsigned value.
18926 * process.c (list_processes_1, create_pty, read_process_output):

18938 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
18939 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
18940 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
18942 * print.c (print_error_message): Avoid int overflow.
18944 * font.c (font_list_entities): Redo for clarity,
18945 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
18947 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
18948 (font_score): Avoid potential overflow in diff calculation.
18950 * fns.c (substring_both): Remove var that is set but not used.
18951 (sxhash): Redo loop for clarity and to avoid wraparound warning.
18953 * eval.c (funcall_lambda): Rename local to avoid shadowing.
18955 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
18956 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
18957 can always succeed if overflow has undefined behavior.
18959 * search.c (boyer_moore, wordify): Remove vars set but not used.
18960 (wordify): Omit three unnecessary tests.
18962 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
18963 All callers changed. This avoids the need for an unused var.
18965 * casefiddle.c (casify_region): Remove var that is set but not used.
18967 * dired.c (file_name_completion): Remove var that is set but not used.
18969 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
18971 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
18972 (Finsert_file_contents): Remove unnecessary code checking fd.
18974 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
18975 Check for integer overflow on size calculations.
18977 * buffer.c (Fprevious_overlay_change): Remove var that is set
18980 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
18981 Remove vars that are set but not used.
18982 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
18983 (timer_check_2): Mark vars as initialized.
18985 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
18987 * image.c (lookup_image): Remove var that is set but not used.
18988 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
18990 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
18991 that are set but not used.
18993 * xfns.c (make_invisible_cursor): Don't return garbage
18994 if XCreateBitmapFromData fails (Bug#8410).
18996 * xselect.c (x_get_local_selection, x_handle_property_notify):
18997 Remove vars that are set but not used.
18999 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

19009 (map_tty_color) [!defined MSDOS]: Likewise.
19011 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
19013 * coding.c: Remove vars that are set but not used.
19014 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
19015 All callers changed.
19016 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
19017 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
19018 (decode_coding_charset): Remove vars that are set but not used.
19020 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
19021 that is set but not used.
19023 * print.c (print_object): Remove var that is set but not used.
19025 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
19026 The gnulib version avoids calling malloc in the usual case,
19027 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
19028 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
19029 * filelock.c (current_lock_owner): Likewise.
19030 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.

19033 (emacs_readlink): New function.
19034 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
19035 ../lib/careadlinkat.h.
19037 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
19039 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
19040 first non-nil return value).

19044 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
19045 if not defined (Bug#8403).

19049 * xdisp.c (display_count_lines): Remove parameter `start',
19050 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.

19054 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
19055 and thereabouts. All callers changed.
19056 (get_per_char_metric): Remove parameter `f', unused since
19057 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

19061 do not dereference NULL upon failed strdup
19062 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
19063 (ns_get_family): Likewise.
19065 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
19067 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.

19104 (Fcommandp): Handle closures.
19105 (Feval): New `lexical' arg.
19106 (eval_sub): New function extracted from Feval. Use it almost

19115 but without exporting it to Lisp.
19117 * doc.c (Fdocumentation, store_function_docstring):
19118 * data.c (Finteractive_form): Handle closures.
19120 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
19123 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
19125 (exec_byte_code): New function extracted from Fbyte_code to handle new
19126 calling convention for byte-code-functions. Add new byte-codes.
19128 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
19130 * alloc.c (Fmake_symbol): Init new `declared_special' field.
19132 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
19134 * xdisp.c (redisplay_internal): Fix prototype.
19136 2011-03-31 Eli Zaretskii <eliz@gnu.org>
19138 * xdisp.c (SCROLL_LIMIT): New macro.
19139 (try_scrolling): Use it when setting scroll_limit.
19140 Limit scrolling to 100 screen lines.
19141 (redisplay_window): Even when falling back on "recentering",
19142 position point in the window according to scroll-conservatively,
19143 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
19145 (try_scrolling): When point is above the window, allow searching
19146 as far as scroll_max, or one screenful, to compute vertical
19147 distance from PT to the scroll margin position. This prevents
19148 try_scrolling from unnecessarily failing when
19149 scroll-conservatively is set to a value slightly larger than the
19150 window height. Clean up the case of PT below the margin at bottom
19151 of window: scroll_max can no longer be INT_MAX. When aggressive
19152 scrolling is in use, don't let point enter the opposite scroll
19153 margin as result of the scroll.
19154 (syms_of_xdisp) <scroll-conservatively>: Document the
19155 threshold of 100 lines for never-recentering scrolling.
19157 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
19159 * dispextern.h (move_it_by_lines):
19160 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
19161 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
19162 (message_log_check_duplicate): Remove parameters `prev_bol' and
19163 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
19164 (redisplay_internal): Remove parameter `preserve_echo_area',
19165 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
19167 * indent.c (Fvertical_motion):
19168 * window.c (window_scroll_pixel_based, Frecenter):
19169 Don't pass `need_y_p' to `move_it_by_lines'.
19171 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
19173 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
19174 steal a few bits to be more compact.
19175 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
19176 Remove unneeded casts.
19178 * bytecode.c (Fbyte_code): CAR and CDR can GC.
19180 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
19182 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
19183 binding" message (bug#7967).
19185 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
19187 Fix more problems found by GCC 4.6.0's static checks.
19189 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
19190 Remove unused local var.
19192 * editfns.c (Fmessage_box): Remove unused local var.
19194 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
19195 (note_mode_line_or_margin_highlight, note_mouse_highlight):
19196 Omit unused local vars.
19197 * window.c (shrink_windows): Omit unused local var.
19198 * menu.c (digest_single_submenu): Omit unused local var.
19199 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
19200 Omit unused local var.
19202 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
19203 Don't assume string length fits in int.
19204 (keyremap_step, read_key_sequence): Use size_t for sizes.
19205 (read_key_sequence): Don't check last_real_key_start redundantly.
19207 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
19208 instead of alloca (Bug#8344).
19210 * eval.c (Fbacktrace): Don't assume nargs fits in int.
19211 (Fbacktrace_frame): Don't assume nframes fits in int.
19213 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
19215 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
19218 * term.c (produce_glyphless_glyph): Remove unnecessary test.
19220 * cm.c (calccost): Turn while-do into do-while, for clarity.
19222 * keyboard.c (syms_of_keyboard): Use the same style as later
19223 in this function when indexing through an array. This also
19224 works around GCC bug 48267.
19226 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
19228 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
19230 * chartab.c (sub_char_table_ref_and_range): Redo for slight
19231 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
19233 * keyboard.c, keyboard.h (num_input_events): Now size_t.
19234 This avoids undefined behavior on integer overflow, and is a bit
19235 more convenient anyway since it is compared to a size_t variable.
19237 Variadic C functions now count arguments with size_t, not int.
19238 This avoids an unnecessary limitation on 64-bit machines, which
19239 caused (substring ...) to crash on large vectors (Bug#8344).
19240 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
19241 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
19242 All variadic functions and their callers changed accordingly.

19245 * editfns.c (general_insert_function): Likewise.
19246 * eval.c (struct backtrace.nargs, interactive_p)
19247 (internal_condition_case_n, run_hook_with_args, apply_lambda)
19248 (funcall_lambda, mark_backtrace): Likewise.
19249 * fns.c (concat): Likewise.
19250 * frame.c (x_set_frame_parameters): Likewise.
19251 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
19252 0 if not found, not -1. All callers changed.
19254 * alloc.c (garbage_collect): Don't assume stack size fits in int.
19255 (stack_copy_size): Now size_t, not int.
19256 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
19258 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
19260 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
19261 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
19262 All callers changed.
19264 * lisp.h (multibyte_char_to_unibyte):
19265 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
19266 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
19267 * character.h (CHAR_TO_BYTE8):
19268 * cmds.c (internal_self_insert):
19269 * editfns.c (general_insert_function):
19270 * keymap.c (push_key_description):
19271 * search.c (Freplace_match):
19272 * xdisp.c (message_dolog, set_message_1): All callers changed.
19274 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
19276 * keyboard.c (safe_run_hook_funcall): New function.
19277 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
19278 don't set the hook to nil, but remove the offending function instead.
19279 (Qcommand_hook_internal): Remove, unused.
19280 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
19281 Vcommand_hook_internal.
19283 * eval.c (enum run_hooks_condition): Remove.
19284 (funcall_nil, funcall_not): New functions.
19285 (run_hook_with_args): Call each function through a `funcall' argument.
19286 Remove `cond' argument, now redundant.
19287 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
19288 (Frun_hook_with_args_until_failure): Adjust accordingly.
19289 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
19291 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
19293 * dispextern.h (string_buffer_position): Remove declaration.
19295 * print.c (strout): Remove parameter `multibyte', unused since
19296 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
19298 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
19299 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
19300 All callers changed.
19302 * w32.c (_wsa_errlist): Use braces for struct initializers.
19304 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
19305 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
19306 All callers changed.
19307 (string_buffer_position): Likewise. Also, make static (it's never
19308 used outside xdisp.c).
19309 (cursor_row_p): Remove parameter `w', unused since
19310 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

19312 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
19313 All callers changed.
19315 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
19317 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

19323 (ns_update_auto_hide_menu_bar): New functions.
19324 (ns_update_begin): Call ns_update_auto_hide_menu_bar.

19328 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
19330 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
19332 * nsmenu.m (runDialogAt): Remove argument to timer_check.
19334 2011-03-27 Glenn Morris <rgm@gnu.org>
19336 * syssignal.h: Replace RETSIGTYPE with void.
19337 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
19338 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
19339 Replace SIGTYPE with void everywhere.
19340 * s/usg5-4-common.h (SIGTYPE): Remove definition.

19343 2011-03-26 Eli Zaretskii <eliz@gnu.org>
19345 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
19346 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
19348 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
19350 * w32.c (read_unc_volume): Use parameter `henum', instead of
19351 global variable `wget_enum_handle'.
19353 * keymap.c (describe_vector): Remove parameters `indices' and
19354 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

19357 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
19359 * keyboard.c (timer_check): Remove parameter `do_it_now',
19360 unused since 1996-04-12T06:01:29Z!rms@gnu.org.
19361 (show_help_echo): Remove parameter `ok_to_overwrite_keystroke_echo',
19362 unused since 2008-04-19T19:30:53Z!monnier@iro.umontreal.ca.
19364 * keyboard.c (read_char):
19365 * w32menu.c (w32_menu_display_help):
19366 * xmenu.c (show_help_event, menu_help_callback):
19367 Adjust calls to `show_help_echo'.
19369 * gtkutil.c (xg_maybe_add_timer):
19370 * keyboard.c (readable_events):
19371 * process.c (wait_reading_process_output):
19372 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
19374 * insdel.c (adjust_markers_gap_motion):
19375 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.
19376 (gap_left, gap_right): Don't call it.
19378 2011-03-25 Chong Yidong <cyd@stupidchicken.com>

19424 * w32term.c (x_set_glyph_string_clipping):
19425 Don't pass uninitialized region to CombineRgn.
19427 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
19429 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.
19430 (w32_wnd_proc): Pass NULL to Windows API, not uninitialized buffer.
19431 (Fx_close_connection): Remove unused variable `i'.

19449 2011-03-23 Julien Danjou <julien@danjou.info>
19451 * term.c (Fsuspend_tty, Fresume_tty):
19452 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
19453 * window.c (temp_output_buffer_show):
19454 * insdel.c (signal_before_change):
19455 * frame.c (Fhandle_switch_frame):

19459 * cmds.c (internal_self_insert):
19460 * callint.c (Fcall_interactively):
19461 * buffer.c (Fkill_all_local_variables):
19462 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
19464 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
19465 unconditionally since it does the check itself.
19467 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
19469 Fix more problems found by GCC 4.5.2's static checks.
19471 * coding.c (encode_coding_raw_text): Avoid unnecessary test
19472 the first time through the loop, since we know p0 < p1 then.
19473 This also avoids a gcc -Wstrict-overflow warning.
19475 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
19476 leading to a memory leak, possible in functions like
19477 load_charset_map_from_file that can allocate an unbounded number
19478 of objects (Bug#8318).
19480 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
19481 that could (at least in theory) be that large.
19483 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
19484 This is less likely to overflow, and avoids undefined behavior if
19485 overflow does occur. All callers changed. Use strtoul to scan
19486 for the unsigned long integer.
19487 (pint2hrstr): Simplify and tune code slightly.
19488 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
19490 * scroll.c (do_scrolling): Work around GCC bug 48228.
19491 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
19493 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
19494 This also avoids a warning with gcc -Wstrict-overflow.
19495 (validate_x_resource_name): Simplify count usage.
19496 This also avoids a warning with gcc -Wstrict-overflow.
19498 * fileio.c (Fcopy_file): Report error if fchown or fchmod
19501 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
19503 * process.c (Fmake_network_process): Use socklen_t, not int,
19504 where POSIX says socklen_t is required in portable programs.
19505 This fixes a porting bug on hosts like 64-bit HP-UX, where
19506 socklen_t is wider than int (Bug#8277).
19507 (Fmake_network_process, server_accept_connection):
19508 (wait_reading_process_output, read_process_output):
19511 * process.c: Rename or move locals to avoid shadowing.
19512 (list_processes_1, Fmake_network_process):
19513 (read_process_output_error_handler, exec_sentinel_error_handler):
19514 Rename or move locals.
19515 (Fmake_network_process): Define label "retry_connect" only if needed.
19516 (Fnetwork_interface_info): Fix pointer signedness.
19517 (process_send_signal): Add cast to avoid pointer signedness problem.
19518 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
19519 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
19521 Make tparam.h and terminfo.c consistent.
19522 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
19523 Include tparam.h instead, since it declares them.
19524 * cm.h (PC): Remove extern decl; tparam.h now does this.
19525 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
19526 * terminfo.c: Include tparam.h, to check interfaces.
19527 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
19528 (tparam): Adjust signature to match interface in tparam.h;
19529 this removes some undefined behavior. Check that outstring and len
19530 are zero, which they always are with Emacs.
19531 * tparam.h (PC, BC, UP): New extern decls.
19533 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
19534 (xftfont_open): Rename locals to avoid shadowing.
19536 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
19537 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
19538 (OTF_TAG_SYM): Omit macro if not needed.
19539 (ftfont_list): Remove unused local.
19540 (get_adstyle_property, ftfont_pattern_entity):
19541 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
19542 Rename locals to avoid shadowing.
19544 * xfont.c (xfont_list_family): Mark var as initialized.
19546 * xml.c (make_dom): Now static.
19548 * composite.c (composition_compute_stop_pos): Rename local to

19585 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
19587 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
19588 This should get cleaned up, so that child_setup has the
19589 same signature on all platforms.

19753 (Fmemory_limit): Cast sbrk's returned value to char *.
19755 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

19761 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
19762 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
19763 to use the following functions instead of these macros.
19764 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
19765 EMACS_INT, since callers assume the returned value fits in int.
19766 (upcase1): Likewise, for UPCASE_TABLE.
19767 (uppercasep, lowercasep, upcase): New static inline functions.
19768 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

19778 (regex_compile, re_match_2_internal): Mark locals as initialized.
19779 (RETALLOC_IF): Define only if needed.
19780 (WORDCHAR_P): Likewise. This one is never needed, but is used
19781 only in a comment talking about a compiler bug, so put inside
19782 the #if 0 of that comment.
19783 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
19784 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

19811 New macros, so that the caller can use some names other than
19812 gcpro1, gcpro2, etc.
19813 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
19815 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
19816 argument, for consistency with GCPRO2_VAR, etc: it is now the
19817 prefix of the variable, not the variable itself. All uses
19819 * dired.c (directory_files_internal, file_name_completion):
19820 Rename locals to avoid shadowing.
19822 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
19823 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
19824 dired.c's scmp function, had undefined behavior.
19825 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
19826 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
19827 * buffer.h: ... to here, because these macros use current_buffer,
19828 and the new implementation with inline functions needs to have
19829 current_buffer in scope now, rather than later when the macros
19831 (downcase, upcase1): New static inline functions.
19832 (DOWNCASE, UPCASE1): Reimplement using these functions.
19833 This avoids undefined behavior in expressions like
19834 DOWNCASE (x) == DOWNCASE (y), which previously suffered
19835 from race conditions in accessing the global variables
19836 case_temp1 and case_temp2.
19837 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
19838 * lisp.h (case_temp1, case_temp2): Remove their decls.
19839 * character.h (ASCII_CHAR_P): Move from here ...
19840 * lisp.h: ... to here, so that the inline functions mentioned
19841 above can use them.
19843 * dired.c (directory_files_internal_unwind): Now static.
19845 * fileio.c (file_name_as_directory, directory_file_name):

19848 (file_name_as_directory): Use const pointers when appropriate.
19849 (Fexpand_file_name): Likewise. In particular, newdir might
19850 point at constant storage, so make it a const pointer.
19851 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
19852 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
19854 (Fset_file_times, Finsert_file_contents, auto_save_error):

19859 to avoid shadowing.
19861 * marker.c (bytepos_to_charpos): Remove; unused.
19863 * lisp.h (verify_bytepos, count_markers): New decls,
19864 so that gcc does not warn that these functions aren't declared.
19866 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
19867 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
19868 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
19869 (copy_text): Remove unused local var.
19871 * filelock.c (within_one_second): Now static.
19872 (lock_file_1): Rename local to avoid shadowing.
19874 * buffer.c (fix_overlays_before): Mark locals as initialized.
19875 (fix_start_end_in_overlays): Likewise. This function should be
19876 simplified by using pointers-to-pointers, but that's a different
19878 (switch_to_buffer_1): Now static.
19879 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
19880 (report_overlay_modification): Rename locals to avoid shadowing.
19882 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
19883 Fix pointer signedness issue.
19884 (sys_subshell): Mark local as volatile if checking for lint,
19885 to suppress a gcc -Wclobbered warning that does not seem to be right.
19886 (MAXPATHLEN): Define only if needed.
19888 * process.c (serial_open, serial_configure): Move decls from here ...
19889 * systty.h: ... to here, so that they can be checked.
19891 * fns.c (get_random, seed_random): Move extern decls from here ...
19892 * lisp.h: ... to here, so that they can be checked.
19894 * sysdep.c (reset_io): Now static.

19900 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
19901 (DENSE_TABLE_SIZE): Remove; unused.
19902 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
19903 (describe_map_tree):
19904 Rename locals to avoid shadowing.
19906 * keyboard.c: Declare functions static if they are not used elsewhere.
