4 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
5 Remove USG and vlimit methods; no longer used these days.
6 Add #error catchall just in case.
8 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
9 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
10 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
11 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
12 (deleted_pid_list, Fdelete_process, create_process)
13 (record_child_status_change, handle_child_signal, deliver_child_signal)
14 (init_process_emacs, syms_of_process):
15 Assume SIGCHLD is defined.
16 (parse_signal): Remove. All uses removed.
17 (abbr_to_signal): New static function.
18 (Fsignal_process): Use it to convert signal names to ints.
19 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
20 kill (getpgrp (), ...).
21 (emacs_sigaction_init): Assume SIGCHLD is defined.
22 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,
23 SIGPIPE, and SIGQUIT are defined. Do not worry about SIGCLD any more.
24 * syssignal.h (EMACS_KILLPG): Remove.
25 All uses replaced by 'kill' with a negative pid.
26 (SIGCHLD): Remove definition, as we now assume SIGCHLD.
27 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
29 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
31 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
32 This will cause a production Emacs to dump core instead of
35 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
37 * frame.c (make_frame): Do not set window's buffer to t.
38 * window.c (Fsplit_window_internal): Likewise. Previously it was
39 used to indicate that the window is being set up. Now we use
40 set_window_buffer for all new windows, so the condition in ...
41 (Fset_window_buffer): ... is always true and can be removed.
43 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
45 Convenient macro to check whether the buffer is hidden.
46 * buffer.h (BUFFER_HIDDEN_P): New macro.
47 * frame.c (make_frame): Use it. Adjust comment.
48 * buffer.c (candidate_buffer): New function.
49 (Fother_buffer, other_buffer_safely): Use it.
51 2012-12-06 Eli Zaretskii <eliz@gnu.org>
53 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
54 if the child process is still running. Instead, exit the wait
55 loop and return zero. (Bug#13086)
57 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
59 * frame.h (x_char_width, x_char_height): Remove prototypes.

67 * keyboard.c (command_loop_1): Remove prototype.
68 (command_loop_2, top_level_1): Add static to match prototype.
70 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
72 Fix a recently-introduced delete-process race condition.
73 * callproc.c, process.h (record_kill_process):
74 New function, containing part of the old call_process_kill.
75 (call_process_kill): Use it.
76 This does not change call_process_kill's behavior.
77 * process.c (Fdelete_process): Use record_kill_process to fix a
78 race condition that could cause Emacs to lose track of a child.
80 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
82 Avoid code duplication between prev_frame and next_frame.
83 * frame.c (candidate_frame): New function. Add comment.
84 (prev_frame, next_frame): Use it. Adjust comment.
86 2012-12-06 Eli Zaretskii <eliz@gnu.org>
88 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
89 fails, signal an error instead of continuing with an empty
91 Encode expanded temp file pattern before passing it to mkstemp or
94 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
95 Encode the file name before passing it to dostounix_filename, in
96 case it will downcase it (under w32-downcase-file-names).
99 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
101 Minor call-process cleanups.
102 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
103 at the same time as other platforms, to simplify analysis.
104 No need for fd0_volatile since we have synch_process_fd.
105 Avoid needless emacs_close; arg is always negative.
107 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
109 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
112 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
114 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
115 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
116 and mouse_face_hidden members to a bitfields.
117 * frame.h (struct frame): Remove set-but-not-used space_width member.
118 (FRAME_SPACE_WIDTH): Remove.
119 * nsterm.m, w32term.c, xterm.c: Adjust users.
120 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
121 member. Adjust users. Convert term_initted, delete_in_insert_mode,
122 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
123 members to a bitfields.
125 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
127 Don't let call-process be a zombie factory (Bug#12980).
128 Fixing this bug required some cleanup of the signal-handling code.
129 As a side effect, this change also fixes a longstanding rare race
130 condition whereby Emacs could mistakenly kill unrelated processes,
131 and it fixes a bug where a second C-g does not kill a recalcitrant
132 synchronous process in GNU/Linux and similar platforms.
133 The patch should also fix the last vestiges of Bug#9488,
134 a bug which has mostly been fixed on the trunk by other changes.
135 * callproc.c, process.h (synch_process_alive, synch_process_death)
136 (synch_process_termsig, sync_process_retcode):
137 Remove. All uses removed, to simplify analysis and so that
138 less consing is done inside critical sections.
139 * callproc.c (call_process_exited): Remove. All uses replaced
140 with !synch_process_pid.
141 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
142 These take the role of what used to be in unwind-protect arg.
144 (block_child_signal, unblock_child_signal):
145 New functions, to avoid races that could kill innocent-victim processes.
146 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
147 (call_process_kill): Record killed processes as deleted, so that
148 zombies do not clutter up the system. Do this inside a critical
149 section, to avoid a race that would allow the clutter.
150 (call_process_cleanup): Fix code so that the second C-g works again
151 on common platforms such as GNU/Linux.
152 (Fcall_process): Create the child process in a critical section,
153 to fix a race condition. If creating an asynchronous process,
154 record it as deleted so that zombies do not clutter up the system.
155 Do unwind-protect for WINDOWSNT too, as that's simpler in the
156 light of these changes. Omit unnecessary call to emacs_close
157 before failure, as the unwind-protect code does that.
158 * callproc.c (call_process_cleanup):
159 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
160 * process.c (record_deleted_pid): New function, containing
161 code refactored out of Fdelete_process.
162 (Fdelete_process): Use it.
163 (process_status_retrieved): Remove. All callers changed to use
165 (record_child_status_change): Remove, folding its contents into ...
166 (handle_child_signal): ... this signal handler. Now, this
167 function is purely a handler for SIGCHLD, and is not called after
168 a synchronous waitpid returns; the synchronous code is moved to
169 wait_for_termination. There is no need to worry about reaping
170 more than one child now.
171 * sysdep.c (get_child_status, child_status_changed): New functions.
172 (wait_for_termination): Now takes int * status and bool
173 interruptible arguments, too. Do not record child status change;
174 that's now the caller's responsibility. All callers changed.
175 Reimplement in terms of get_child_status.
176 (wait_for_termination_1, interruptible_wait_for_termination):
177 Remove. All callers changed to use wait_for_termination.
178 * syswait.h: Include <stdbool.h>, for bool.
179 (record_child_status_change, interruptible_wait_for_termination):
181 (record_deleted_pid, child_status_changed): New decls.
182 (wait_for_termination): Adjust to API changes noted above.
184 * bytecode.c, lisp.h (Qbytecode): Remove.
185 No longer needed after 2012-11-20 interactive-p changes.
187 2012-12-03 Eli Zaretskii <eliz@gnu.org>
189 * xdisp.c (redisplay_window): If the cursor is visible, but inside
190 the scroll margin, move point outside the margin. (Bug#13055)
192 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
194 * gtkutil.c (my_log_handler): New function.
195 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
197 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
199 * lisp.h (modify_region): Rename to...
200 (modify_region_1): ...new prototype.
201 * textprop.c (modify_region): Now static. Adjust users.
202 * insdel.c (modify_region): Rename to...
203 (modify_region_1): ...new function to work with current buffer.
204 Adjust comment and users. Use true and false for booleans.
206 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
208 * alloc.c (free_save_value): New function.
209 (safe_alloca_unwind): Use it.
210 * lisp.h (free_save_value): New prototype.
211 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
213 (save_excursion_restore): Adjust to match saved data structure.
214 Use free_save_value to offload some work from GC. Drop obsolete
217 2012-12-03 Chong Yidong <cyd@gnu.org>
219 * fileio.c (Vauto_save_list_file_name): Doc fix.
221 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
223 * w32fns.c: Remove prototype of atof.
224 (syspage_mask): Declared DWORD_PTR, for compatibility with 64-bit
226 (file_dialog_callback): Declared UINT_PTR.
228 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
231 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
232 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
235 2012-12-03 Glenn Morris <rgm@gnu.org>
237 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
239 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
241 Fix xpalloc confusion after memory is exhausted.
242 * alloc.c (xpalloc): Comment fix.
243 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
244 and signals an error, do not clear charset_table_size, as
245 charset_table is still valid.
246 * doprnt.c (evxprintf): Clear *BUF after freeing it.
248 Use execve to avoid need to munge environ (Bug#13054).
249 * callproc.c (Fcall_process):
250 * process.c (create_process):
251 Don't save and restore environ; no longer needed.
252 * callproc.c (child_setup):
253 Use execve, not execvp, to preserve environ.
255 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
257 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
259 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
261 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
262 display for sliced images (Bug#10500).
264 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
266 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
268 * doc.c (Fdocumentation): Re-add handling of function-documentation,
269 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
271 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
273 * xdisp.c (window_outdated): Remove eassert since it hits
274 some suspicious corner cases (see Bug#13007 and Bug#13012).
275 (mode_line_update_needed): New function.
276 (redisplay_internal, redisplay_window): Use it.
277 (ensure_selected_frame): New function.
278 (redisplay_internal, unwind_redisplay): Use it.
279 (redisplay_internal): Move comment about buffer_shared...
280 (buffer_shared_and_changed): ...near to its real use.
282 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
284 * callproc.c (Fcall_process): Don't misreport vfork failure.
286 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
288 * callproc.c (Fcall_process): Fix vfork portability problems.
289 Do not assume that fd[0], count, filefd, and save_environ survive
290 vfork. Fix bug whereby wrong errno value could be reported for
291 pipe failure. Some minor cleanups, too, as follows. Move buf and
292 bufsize to the context where they're needed. Change new_argv to
293 be of type char **, as this is more convenient and avoids casts.
294 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
295 Now local constants, not macros.
297 2012-11-18 Kenichi Handa <handa@gnu.org>
299 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
300 for the variable "f".
302 2012-11-13 Kenichi Handa <handa@gnu.org>
304 * font.c (font_unparse_xlfd): Exclude special characters from the
305 generating XLFD name.
307 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
309 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.
310 * dired.c (stat_uname, stat_gname):

327 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
330 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
331 highlighting on the frame was cleared. Prevents assertion
332 violations when repeatedly clicking on the "Top" link of the
333 "bread-crumbs" in Info buffers.
335 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>

345 2012-11-24 Eli Zaretskii <eliz@gnu.org>
347 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
348 between bpos_covered and bpos_max. This fixes cursor display when
349 several display strings follow each other.
351 * .gdbinit (pgx): If the glyph's object is a string, display the
352 pointer to string data, rather than the value of the string object
353 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
355 * indent.c (Fvertical_motion): If the starting position is covered
356 by a display string, return to one position before that, to avoid
357 overshooting it inside move_it_to. (Bug#12930)
359 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>

369 asked_for_visible and menubar_active members. Drop
370 unused pending_menu_activation member.
371 * xterm.h (struct x_output): Drop outdated #if 0 code.
372 Use bitfields for explicit_parent, asked_for_visible,
373 has_been_visible and net_wm_state_hidden_seen members.
375 2012-11-23 Eli Zaretskii <eliz@gnu.org>

378 of a literal "/". (Bug#12955)
379 (gl-stamp): Invoke fc.exe directly, not through cmd.
381 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>

384 * dired.c: Assume HAVE_DIRENT_H.
385 (NAMLEN): Remove, replacing with ...
386 (dirent_namelen): New function. All uses changed. Use the GNU macro
387 _D_EXACT_NAMELEN if available, as it's faster than strlen.
388 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
389 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
390 * makefile.w32-in (DIR_H): Remove. All uses replaced with
392 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
393 * ndir.h: Rename to ../nt/inc/dirent.h.
394 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
395 Do not include <dirent.h>; no longer needed.
396 * w32.c: Include <dirent.h> rather than "ndir.h".
398 2012-11-23 Chong Yidong <cyd@gnu.org>
400 * xftfont.c (xftfont_open): Remove duplicate assignment.
402 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
404 * alloc.c (Fgarbage_collect): Unblock input after clearing
405 gc_in_progress to avoid note_mouse_highlight glitch with GC.
406 * frame.h (FRAME_MOUSE_UPDATE): New macro.
407 * msdos.c (IT_frame_up_to_date): Use it here...
408 * w32term.c (w32_frame_up_to_date): ...here...
409 * xterm.c (XTframe_up_to_date): ...and here...
410 * nsterm.m (ns_frame_up_to_date): ...but not here.
411 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
413 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
414 Do not check whether GC is in progress.
416 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
418 * xdisp.c (window_buffer_changed): New function.
419 (update_menu_bar, update_tool_bar): Use it to
420 simplify large 'if' statements.
421 (redisplay_internal): Generalize commonly used
422 'tail' and 'frame' local variables.
424 2012-11-22 Eli Zaretskii <eliz@gnu.org>
426 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
427 with Windows system header.
429 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
431 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
432 * alloc.c: Assume unistd.h exists.
433 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
434 * sysdep.c (get_current_dir_name): Assume getcwd exists.
435 (getwd) [USG]: Remove; no longer needed.
436 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.

452 2012-11-21 Eli Zaretskii <eliz@gnu.org>
454 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
455 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
456 Define for the MSVC compiler.
458 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
460 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
461 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
462 dostounix_filename. Prevents crashes down the road, because
463 dostounix_filename assumes it gets a unibyte string. Reported by
464 Michel de Ruiter <michel@sentient.nl>, see
465 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html

475 Test NILP rather than Qunbound.
476 (Ffmakunbound): Set to Qnil.
477 (Fsymbol_function): Never signal an error.

487 (buffer_shared_and_changed): New function.
488 (prepare_menu_bars, redisplay_internal): Use it to
489 decide whether all windows or frames should be updated.
490 (window_outdated): New function.
491 (text_outside_line_unchanged_p, redisplay_window): Use it.
492 (redisplay_internal): Likewise. Fix indentation.
494 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
496 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
497 (syms_of_eval): Remove corresponding defsubr.
498 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
500 2012-11-19 Daniel Colascione <dancol@dancol.org>
502 * w32fns.c (Fx_file_dialog):
503 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
504 cygwin_convert_file_name*.
506 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
507 Rename cygwin_convert_path* to cygwin_convert_file_name*.
509 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
511 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
513 2012-11-18 Eli Zaretskii <eliz@gnu.org>
515 * w32select.c: Include w32common.h before w32term.h, so that
516 windows.h gets included before w32term.h uses some of its
519 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
521 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
523 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
525 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
527 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
528 (ns_select): Return at once if events are held (Bug#12834).
530 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
532 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
533 Needed following 2012-10-20 change. (Bug#12902)
535 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
537 * w32proc.c (waitpid): Remove unused label get_result.
539 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
541 * makefile.w32-in (SYSWAIT_H): New macro.
542 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
543 ($(BLD)/sysdep.$(O)): Update dependencies.
545 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
547 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
548 * callproc.c (relocate_fd): Assume F_DUPFD.
549 * emacs.c, term.c (O_RDWR): Remove.
550 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
551 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
552 * nsterm.m: Assume <fcntl.h> exists.
553 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
554 (create_pty, Fmake_network_process, server_accept_connection)
555 (wait_reading_process_output, init_process_emacs):
557 (wait_reading_process_output): Put in a special case for WINDOWSNT
558 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
559 It's not clear this is needed, but it's a more-conservative change.
560 (create_process): Assume FD_CLOEXEC.
561 (create_process, create_pty): Assume O_NOCTTY.
562 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
563 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
564 Omit if not DOS_NT, since F_GETFL is not defined there.
565 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
566 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
568 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
569 lack it, since gnulib guarantees this.
570 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
572 2012-11-17 Eli Zaretskii <eliz@gnu.org>
574 * w32.c (faccessat): Pretend that directories have the execute bit
575 set. Emacs expects that, e.g., in files.el:cd-absolute.
577 * w32proc.c (create_child): Don't clip the PID of the child
578 process to fit into an Emacs integer, as this is no longer a
580 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
581 reaping only the process specified by PID argument, if that is
582 positive. Use PID instead of dead_child to know which process to
583 reap. Wait for the child to die only if WNOHANG is not in
585 (sys_select): Don't set dead_child.
587 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
588 as it is no longer needed.
590 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
592 (record_child_status_change): Remove the setting of
593 record_at_most_one_child for the !WNOHANG case.
595 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
597 Fix problems in ns port found by static checking.
598 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
599 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
600 not to process group.
601 (ns_select): Use emacs_write, not write, as that's more robust
602 in the presence of signals.
603 (fd_handler:): Check for read errors.
605 2012-11-16 Glenn Morris <rgm@gnu.org>
607 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
609 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
611 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
613 2012-11-16 Eli Zaretskii <eliz@gnu.org>
615 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
616 use the same value of thread handle.
617 (start_timer_thread): If the timer thread exited (due to error),
618 clean up by closing the two handles it used. Duplicate the caller
619 thread's handle here, so it gets duplicated only once, when
620 launching the timer thread. Set priority of the timer thread, not
622 (getitimer): Don't duplicate the caller thread's handle here.
625 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
627 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
630 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
632 Remove no-longer-used pty_max_bytes variable.
633 * process.c (pty_max_bytes): Remove; unused.
634 (send_process): Do not set it.
636 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
638 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
641 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
643 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
644 This follows up on the 2012-09-29 patch that removed indirection
645 for the 'function' field. Reported by Sergey Vinokurov in
646 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
648 2012-11-14 Eli Zaretskii <eliz@gnu.org>
650 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
651 different name, as the MS runtime does not have such a function,
652 and probably never will.) All callers changed. Ignore DIRFD
653 value if PATH is an absolute file name, to match Posix spec
654 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
657 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
659 * xdisp.c (echo_area_display, redisplay_internal):
660 Omit redundant check whether frame_garbaged is set.
662 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
664 Use faccessat, not access, when checking file permissions (Bug#12632).
665 This fixes a bug that has been present in Emacs since its creation.
666 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
667 which must set some sort of record. (Torek's bug report was against
668 a predecessor of GNU Emacs, but GNU Emacs happened to have the
669 same common flaw.) See Torek's Usenet posting
670 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
671 Posted: Fri Apr 8 14:18:56 1983.
672 * Makefile.in (LIB_EACCESS): New macro.
674 * callproc.c (init_callproc):
675 * charset.c (init_charset):
676 * fileio.c (check_existing, check_executable, check_writable)
678 * lread.c (openp, load_path_check):
679 * process.c (allocate_pty):
681 Use effective UID when checking permissions, not real UID.
682 * callproc.c (init_callproc):
683 * charset.c (init_charset):
684 * lread.c (load_path_check, init_lread):
685 Test whether directories are accessible, not merely whether they exist.
686 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
687 * fileio.c (check_existing, check_executable, check_writable)
689 Use symbolic names instead of integers for the flags, as they're
691 (check_writable): New arg AMODE. All uses changed.
692 Set errno on failure.
693 (Ffile_readable_p): Use faccessat, not stat + open + close.
694 (Ffile_writable_p): No need to call check_existing + check_writable.
695 Just call check_writable and then look at errno. This saves a syscall.
696 dir should never be nil; replace an unnecessary runtime check
697 with an eassert. When checking the parent directory of a nonexistent
698 file, check that the directory is searchable as well as writable, as
699 we can't create files in unsearchable directories.
700 (file_directory_p): New function, which uses 'stat' on most platforms
701 but faccessat with D_OK (for efficiency) if WINDOWSNT.
702 (Ffile_directory_p, Fset_file_times): Use it.
703 (file_accessible_directory_p): New function, which uses a single
704 syscall for efficiency.
705 (Ffile_accessible_directory_p): Use it.
706 * xrdb.c (file_p): Use file_directory_p.
707 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
708 * lread.c (openp): When opening a file, use fstat rather than
709 stat, as that avoids a permissions race. When not opening a file,
710 use file_directory_p rather than stat.
711 (dir_warning): First arg is now a usage string, not a format.
712 Use errno. All uses changed.
713 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
714 that merely introduced a race.
715 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
716 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
717 and similarly for the other O_* flags.
718 * w32.c (sys_faccessat): Rename from sys_access and switch to
719 faccessat's API. All uses changed.
720 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
721 (magic_db): Rename from magic_file_p.
722 (magic_db, search_magic_path): Return an XrmDatabase rather than a
723 char *, so that we don't have to test for file existence
724 separately from opening the file for reading. This removes a race
725 fixes a permission-checking problem, and simplifies the code.
727 (file_p): Remove; no longer needed.
729 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
731 Omit glyphs initialization at startup.
732 * dispnew.c (glyphs_initialized_initially_p): Remove.
733 (adjust_frame_glyphs_initially): Likewise. Adjust users.
734 (Fredraw_frame): Move actual code from here...
735 (redraw_frame): ...to here. Add eassert. Adjust comment.
736 (Fredraw_display): Use redraw_frame.
737 * xdisp.c (clear_garbaged_frames): Likewise.
739 2012-11-13 Eli Zaretskii <eliz@gnu.org>
741 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
742 passed to pint2str and pint2hrstr to be at most the size of the
743 frame's decode_mode_spec_buffer. This avoids crashes with very
744 large values of FIELD_WIDTH argument to decode_mode_spec.
747 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
749 Fix a race with verify-visited-file-modtime (Bug#12863).
750 Since at least 1991 Emacs has ignored an mtime difference of no
751 more than one second, but my guess is that this was to work around
752 file system bugs that were fixed long ago. Since the race is
753 causing problems now, let's remove that code.
754 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
755 whose time stamp is off by no more than a second. Insist that the
756 file time stamps match exactly.
758 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
760 * frame.h (struct frame): Convert external_tool_bar member to
761 1-bit unsigned bitfield.
762 * termhooks.h (struct terminal): Remove mouse_moved member since
763 all users are long dead. Adjust comment on mouse_position_hook.
765 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
767 Simplify by using FOR_EACH_FRAME here and there.
768 * frame.c (next_frame, prev_frame, other_visible_frames)
769 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
770 * w32term.c (x_window_to_scroll_bar): Likewise.
771 * window.c (window_list): Likewise.
772 * xdisp.c (x_consider_frame_title): Likewise.
773 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
774 * xfns.c (x_window_to_frame, x_any_window_to_frame)
775 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
776 * xmenu.c (menubar_id_to_frame): Likewise.
777 * xselect.c (frame_for_x_selection): Likewise.
778 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
779 (x_window_to_menu_bar): Likewise.
780 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
782 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
784 * data.c (Qdefalias_fset_function): Now static.
786 Another tweak to vectorlike_header change.
787 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
788 Remove, and replace all uses with ...
789 (next_in_free_list, set_next_in_free_list):
790 New functions, which respect C's aliasing rules better.
792 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
794 * window.c (list4i): Rename from 'quad'. All uses changed.
795 Needed because <sys/types.h> defines 'quad' on Solaris 10.
797 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
799 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
800 warning about mixing declarations and code in ISO C90.
802 2012-11-10 Martin Rudalics <rudalics@gmx.at>
804 * window.c (Fsplit_window_internal): Set combination limit of
805 new parent window to t iff Vwindow_combination_limit is t;
806 fixing a regression introduced with the change from 2012-09-22.
807 (Fset_window_combination_limit): Fix doc-string.
809 2012-11-10 Eli Zaretskii <eliz@gnu.org>
811 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
812 amount when the scroll margins are too large. When scrolling
813 backwards in the buffer, give up if cannot reach point or the
814 scroll margin within a reasonable number of screen lines.
815 Fixes point position in window under scroll-up/down-aggressively when
816 point is positioned many lines beyond the window top/bottom.
819 * ralloc.c (relinquish): If real_morecore fails to return memory
820 to the system, don't crash; instead, leave the last heap
821 unchanged and return. (Bug#12774)
823 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
825 * lisp.h (AUTOLOADP): New macro.
826 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
827 * data.c (Ffset): Remove special ad-advice-info handling.
828 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
830 (Finteractive_form): Simplify.
831 (Fquo): Don't insist on having at least 2 arguments.
832 (Qdefalias_fset_function): New var.
834 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
836 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
838 * nsfont.m (Qcondensed, Qexpanded): New variables.
839 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
840 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
842 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
844 Fix recently introduced crash on MS-Windows (Bug#12839).
845 * w32term.h (struct scroll_bar): Use convenient header.
846 (SCROLL_BAR_VEC_SIZE): Remove.
847 * w32term.c (x_scroll_bar_create): Use VECSIZE.
849 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
851 Tweak last vectorlike_header change.
852 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
853 vectorlike object on the free list. This is introduced to avoid
854 some (but not all) pointer casting and aliasing problems, see
855 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
856 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
858 (xvectype, xvecsize): Use them to examine Lisp_Object values.
860 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
862 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
863 been removed, so remove them here also.
865 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
867 * doc.c (Fdocumentation): Handle new property
868 dynamic-docstring-function to replace the old ad-advice-info.
870 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
872 * fns.c (Qeql, hashtest_eq): Now static.
874 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
876 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
877 * fns.c (hashfn_eq, hashfn_eql, sxhash):
878 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
879 * buffer.c (compare_overlays): Use XLI rather than XHASH.
881 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
883 Use same hash function for hashfn_profiler as for hash_string etc.
884 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
885 * lisp.h (sxhash_combine): New inline function, with the contents
886 of the old SXHASH_COMBINE.
887 * profiler.c (hashfn_profiler): Use it, instead of having a
888 special hash function containing a comparison that always yields 1.
890 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
892 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
893 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
894 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
897 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
899 * image.c (xpm_make_color_table_h): Fix compiler error because
900 make_hash_table changed.
902 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
904 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
906 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
908 Use ad-hoc comparison function for the profiler's hash-tables.
909 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
910 (make_log): Use them.
911 (handle_profiler_signal): Don't inhibit quit any longer since we don't
912 call Fequal any more.
913 (Ffunction_equal): New function.
914 (cmpfn_profiler, hashfn_profiler): New functions.
915 (syms_of_profiler): Initialize them.
916 * lisp.h (struct hash_table_test): New struct.

921 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
922 (hash_lookup, hash_remove_from_table): Move assertion checking of
923 hashfn result here. Check hash-equality before calling cmpfn.
924 (Fmake_hash_table): Adjust call to make_hash_table.
925 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.
926 (syms_of_fns): Initialize them.

935 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
936 value of w32-scroll-lock-modifier is neither nil nor one of the
937 known key modifiers. (Bug#12806)
939 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
941 Shrink struct vectorlike_header to the only size field.
942 * lisp.h (enum pvec_type): Avoid explicit enum member values.
944 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
945 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
946 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
947 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
948 information from the vector header. Adjust comment.

953 (struct vectorlike_header): Remove next member. Adjust comment.
954 (struct Lisp_Subr): Add convenient header. Adjust comment.
955 (allocate_pseudovector): Adjust prototype.
956 * alloc.c (mark_glyph_matrix, mark_face_cache, allocate_string)
957 (sweep_string, lisp_malloc): Remove useless prototypes.
958 (enum mem_type): Adjust comment.
959 (NEXT_IN_FREE_LIST): New macro.
960 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
961 (Fmake_bool_vector): Likewise.
962 (struct large_vector): New type to represent allocation unit for
963 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
964 (large_vectors): Change type to struct large_vector.
965 (allocate_vector_from_block): Simplify.
966 (PSEUDOVECTOR_NBYTES): Replace with...
967 (vector_nbytes): ...new function. Adjust users.
968 (sweep_vectors): Adjust processing of large vectors.
969 (allocate_vectorlike): Likewise.
970 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
971 Add easserts. Adjust XSETPVECTYPESIZE usage.
972 (allocate_buffer): Use BUFFER_PVEC_INIT.
973 (live_vector_p): Adjust to match large vector.
974 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
975 * buffer.h (struct buffer): Add next member.
976 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
978 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
979 * fns.c (internal_equal): Adjust to match enum pvec_type change.
980 (copy_hash_table): Adjust to match vector header change.
981 * lread.c (defsubr): Use XSETPVECTYPE.
982 * .gdbinit (xpr, xbacktrace): Adjust to match vector header change.
983 (xvectype): Likewise. Print PVEC_NORMAL_VECTOR for regular vectors.
984 (xvecsize): New command.
986 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
988 * keyboard.c (event_to_kboard): Do not dereference
989 frame_or_window field of SELECTION_REQUEST_EVENT
990 and SELECTION_CLEAR_EVENT events (Bug#12814).
991 * xterm.h (struct selection_input_event): Adjust comment.
993 2012-11-07 Eli Zaretskii <eliz@gnu.org>
995 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
996 such as Scroll Lock, if the respective keys are treated as
997 function keys, not as modifiers. This avoids destroying non-ASCII
998 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
1000 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
1002 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
1004 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1006 Restore some duplicate definitions (Bug#12814).
1007 This undoes part of the 2012-11-03 changes. Some people build
1008 with plain -g rather than with -g3, and they need the duplicate
1009 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
1010 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
1011 Define as macros, as well as as enums or as constants.
1013 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
1015 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
1016 to keypad keys (Bug#12816).
1018 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1020 Minor adjustments of recently-changed frame functions.
1021 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
1022 known to be a frame (we're in the FRAMEP branch).
1023 * lisp.h (Qframep): Remove decl. frame.h declares this.
1024 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
1025 since they're meant for Lisp fixnum values.
1027 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1029 * window.c (Fwindow_combination_limit): Revert to the only
1030 required argument and adjust docstring as suggested in
1031 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
1032 by Martin Rudalics <rudalics@gmx.at>.
1034 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1036 Widely used frame validity and checking functions.
1037 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
1038 * frame.c (decode_live_frame, decode_any_frame): New functions.
1039 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
1040 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
1041 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
1042 (Fframe_pointer_visible_p): Use decode_any_frame.
1043 (Fmake_frame_visible, Fmake_frame_invisible, Ficonify_frame)
1044 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
1045 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
1046 (Fframe_focus): Likewise. Allow zero number of arguments.
1048 (frame_buffer_list, frame_buffer_predicate): Remove.
1049 * lisp.h (frame_buffer_predicate): Remove prototype.
1050 * buffer.c (Fother_buffer): Use decode_any_frame.
1051 * xdisp.c (Ftool_bar_lines_needed): Likewise.
1052 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
1053 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
1054 (Fclose_font, Ffont_info): Use decode_live_frame.
1055 * fontset.c (check_fontset_name): Likewise.
1056 * terminal.c (Fframe_terminal): Likewise.
1057 * w32fns.c (check_x_frame): Likewise.
1058 * window.c (Fminibuffer_window, Fwindow_at)
1059 (Fcurrent_window_configuration): Likewise.
1060 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
1061 Likewise. Allow zero number of arguments. Adjust docstring.
1062 * dispnew.c (Fredraw_frame): Likewise.
1063 * xfaces.c (frame_or_selected_frame): Remove.
1064 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
1065 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
1066 (Fframe_face_alist): Use decode_live_frame.
1067 * xfns.c (check_x_frame): Likewise.
1069 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1071 * window.c (quad): New function.
1072 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
1073 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
1074 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
1075 (Fwindow_line_height): Use it.
1076 (Fwindow_fringes): Use list3.
1077 (Fwindow_scroll_bars): Use list4.
1078 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
1079 (Fwindow_combination_limit): Allow zero number of arguments.
1081 2012-11-05 Eli Zaretskii <eliz@gnu.org>
1083 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
1085 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
1086 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
1087 file descriptor 2 for standard error. (Bug#12805)
1089 2012-11-05 Chong Yidong <cyd@gnu.org>
1091 * process.c (wait_reading_process_output): Revert previous change.
1093 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
1095 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
1096 This removes code that has been obsolete since around 1990.
1097 * callproc.c (Fcall_process):
1099 * process.c (create_process):
1100 * term.c (dissociate_if_controlling_tty):
1101 Assume setsid exists.
1102 * callproc.c (child_setup): Assume setpgid exists and behaves as
1103 per POSIX.1-1988 or later.
1104 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
1105 * emacs.c (shut_down_emacs):
1106 * sysdep.c (sys_suspend, init_foreground_group):
1107 Assume getpgrp behaves as per POSIX.1-1998 or later.
1108 * msdos.c (setpgrp): Remove.
1109 (tcgetpgrp, setpgid, setsid): New functions.
1110 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
1111 * term.c (no_controlling_tty): Remove; unused.
1112 * w32proc.c (setpgrp): Remove.
1113 (setsid, tcgetpgrp): New functions.
1115 Simplify by assuming __fpending.
1116 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
1117 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
1118 Do not assume that __fpending's result fits in int.
1120 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
1122 Remove EMACS_OUTQSIZE+sleep hack.
1123 * dispnew.c (update_frame_1): Remove hack for terminals slower
1124 than 2400 bps, which throttled Emacs by having it sleep.
1125 This code hasn't worked since at least 2007, when the multi-tty stuff
1126 was added, and anyway those old terminals are long dead.
1127 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
1128 without the dispnew.c change, as dispnew.c doesn't include systty.h.
1130 Fix data-loss with --version (Bug#9574).
1131 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
1132 as we can't assume that emacs_strerror is initialized, and strerror
1133 is good enough here.
1134 (main): Invoke atexit earlier, to catch earlier instances of
1135 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
1137 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
1139 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
1140 (keyDown): Remap keypad keys to X11 virtual key codes.
1142 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
1144 Fix data-loss with --batch (Bug#9574).
1145 * emacs.c: Include <close-stream.h>.
1146 (close_output_streams): New function.
1147 (main): Pass it to atexit, so that Emacs closes stdout and stderr
1148 and handles errors appropriately.
1149 (Fkill_emacs): Don't worry about flushing, as close_output_stream
1152 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
1153 The symptom is a diagnostic "GLib-WARNING **: In call to
1154 g_spawn_sync(), exit status of a child process was requested but
1155 SIGCHLD action was set to SIG_IGN and ECHILD was received by
1156 waitpid(), so exit status can't be returned." The diagnostic
1157 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
1158 The real bug is a race condition between Emacs and glib: Emacs
1159 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
1160 so that glib can't find it. Work around the bug by invoking
1161 waitpid only on subprocesses that Emacs itself creates.
1162 * process.c (create_process, record_child_status_change):
1163 Don't use special value -1 in pid field, as the caller now must
1164 know the pid rather than having the callee infer it.
1165 The inference was sometimes incorrect anyway, due to another race.
1166 (create_process): Set new 'alive' member if child is created.
1167 (process_status_retrieved): New function.
1168 (record_child_status_change): Use it.
1169 Accept negative 1st argument, which means to wait for the
1170 processes that Emacs already knows about. Move special-case code
1171 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
1172 processes that have already been waited for, by testing and
1173 clearing new 'alive' member.
1174 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
1175 now does this internally.
1176 (handle_child_signal): Let record_child_status_change do all
1177 the work, since we do not want to reap all exited child processes,
1178 only the child processes that Emacs itself created.
1179 * process.h (Lisp_Process): New boolean member 'alive'.
1181 Omit duplicate definitions no longer needed with gcc -g3.
1182 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
1183 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
1184 Define only as macros. There's no longer any need to also define
1185 these symbols as enums or as constants, since we now assume
1186 gcc -g3 when debugging.
1188 2012-11-03 Eli Zaretskii <eliz@gnu.org>
1190 * lisp.mk: Adjust comments to the fact that term/internal is now
1191 loaded from loadup.el.
1193 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
1194 (msdos_fatal_signal): New function.
1195 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
1198 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
1199 for GCC versions before 4.
1200 (emacs_raise): Define to call msdos_fatal_signal.
1202 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
1203 iterator when starting in the middle of a display or overlay
1206 2012-11-03 Chong Yidong <cyd@gnu.org>
1208 * process.c (wait_reading_process_output): Clean up the last
1211 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
1213 * process.c (wait_reading_process_output): Avoid a race condition
1214 with SIGIO delivery (Bug#11536).
1216 2012-11-03 Chong Yidong <cyd@gnu.org>
1218 * buffer.c (cursor_type): Untabify docstring.
1220 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1222 * frame.h (struct frame): Drop can_have_scroll_bars member
1223 which is meaningless for a long time. Adjust comments.
1224 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
1225 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
1227 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1229 * window.c (decode_next_window_args): Update window arg after
1230 calling decode_live_window and so fix crash reported at
1231 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
1232 by Juanma Barranquero <lekktu@gmail.com>.
1233 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
1234 * font.c (Ffont_at): Likewise.
1236 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
1238 * widget.c (resize_cb): New function.
1239 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
1240 (EmacsFrameResize): Check if all is up to date before changing frame
1243 2012-11-02 Eli Zaretskii <eliz@gnu.org>
1245 Implement backtrace output for fatal errors on MS-Windows.
1246 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
1247 (BACKTRACE_LIMIT_MAX): New macro.
1248 (w32_backtrace): New function.
1249 (emacs_abort): Use w32_backtrace when the user chooses not to
1250 attach a debugger. Update the text of the abort dialog.
1252 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1254 Window-related stuff cleanup here and there.
1255 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
1256 Use decode_any_window.
1257 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
1258 * xdisp.c (Fformat_mode_line): Likewise.
1259 * font.c (Ffont_at): Use decode_live_window.
1260 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
1261 * window.c (decode_next_window_args): Likewise.
1262 (decode_any_window): Remove static.
1263 * window.h (decode_any_window): Add prototype.
1264 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
1265 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
1268 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1270 Remove pad from struct input_event.
1271 * termhooks.h (struct input_event): Remove padding field.
1273 * keyboard.c (event_to_kboard): Simplify because frame_or_window
1274 member is never cons for a long time. Adjust comment.
1275 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
1276 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
1277 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
1278 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
1280 2012-11-01 Eli Zaretskii <eliz@gnu.org>
1282 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
1284 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
1286 Fix crash when using Emacs as commit editor for git (Bug#12697).
1287 * callproc.c (setpgrp): Remove macro, as we now use setpgid
1288 and it is configured in conf_post.h.
1289 (Fcall_process): Don't invoke both setsid and setpgid; the former
1290 is enough, if it exists.
1291 * callproc.c (Fcall_process, child_setup):
1292 * process.c (create_process): Use setpgid.
1293 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
1295 * dispnew.c (init_display): Initialize the foreground group
1296 if we are running a tty display.
1297 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
1298 * lisp.h (init_foreground_group): New decl.
1299 * sysdep.c (inherited_pgroup): New static var.
1300 (init_foreground_group, tcsetpgrp_without_stopping)
1301 (narrow_foreground_group, widen_foreground_group): New functions.
1302 (init_sys_modes): Narrow foreground group.
1303 (reset_sys_modes): Widen foreground group.
1305 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
1307 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
1309 2012-10-31 Martin Rudalics <rudalics@gmx.at>
1311 * minibuf.c (read_minibuf): Restore current buffer since
1312 choose_minibuf_frame calling Fset_frame_selected_window may
1313 change it (Bug#12766).
1315 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
1317 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
1319 2012-10-30 Kenichi Handa <handa@gnu.org>
1321 * font.c (Ffont_at): If WINDOW is specified and it is not
1322 displaying the current buffer, signal an error.
1324 2012-10-29 Daniel Colascione <dancol@dancol.org>
1326 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
1327 In preparation for fixing bug#12739, move these functions from
1330 * coding.h, coding.c: ... to here, and compile them only when
1331 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
1332 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
1334 2012-10-28 Eli Zaretskii <eliz@gnu.org>
1336 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
1337 (timer_loop, getitimer, setitimer): Use it instead of
1338 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
1340 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
1343 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
1345 * nsterm.m (NO_APPDEFINED_DATA): New define.
1346 (last_appdefined_event_data): New variable
1347 (last_appdefined_event): Remove.
1348 (ns_select): Initialize t from last_appdefined_event_data instead
1349 of [last_appdefined_event data1].
1350 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
1351 remove last_appdefined_event (Bug#12698).
1353 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
1355 * frame.c (x_set_font): Catch internal error.
1357 2012-10-27 Eli Zaretskii <eliz@gnu.org>
1359 Avoid overflow in w32 implementation of interval timers.
1360 When possible, for ITIMER_PROF count only times the main thread
1362 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
1363 'volatile ULONGLONG' types. All the other data which was
1364 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
1365 (GetThreadTimes_Proc): New typedef.
1366 (w32_get_timer_time): New function, returns a suitable time value
1368 (timer_loop): Enter critical section when accessing ULONGLONG
1369 values of the itimer_data struct, as these accesses are no longer
1370 atomic. Call 'w32_get_timer_time' instead of 'clock'.
1371 Remove unused variable.
1372 (init_timers): Initialize s_pfn_Get_Thread_Times.
1373 (start_timer_thread): Don't assign itimer->caller_thread here.
1374 (getitimer): Assign itimer->caller_thread here.
1375 (setitimer): Always call getitimer to get the value of ticks_now.
1376 (sys_spawnve): Avoid compiler warning about format mismatch.
1378 2012-10-26 Eli Zaretskii <eliz@gnu.org>
1380 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
1381 mouse movement events if the menu bar is active. This avoids
1382 producing a busy "hour-glass" cursor by Windows if the mouse
1383 pointer is positioned over a tooltip shown for some menu item.
1385 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
1387 Don't assume process IDs fit in int.
1388 * emacs.c (shut_down_emacs) [!DOS_NT]:
1389 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
1390 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:

1872 * unexw32.c, unexcw.c: Include w32common.h.
1874 * emacs.c (main): Use (defined (WINDOWSNT) || defined
1875 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
1876 to call syms_of_w32select.
1878 * cygw32.h: Remove obsolete EXFUN declarations.
1880 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
1882 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
1883 of w32inevt.o from SOME_MACHINE_OBJECTS.
1885 2012-10-08 Daniel Colascione <dancol@dancol.org>
1887 * image.c: Permanent fix for JPEG compilation issue --- limit
1888 jpeglib `boolean' redefinition to Cygwin builds.
1890 2012-10-08 Eli Zaretskii <eliz@gnu.org>
1892 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
1894 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
1897 2012-10-08 Daniel Colascione <dancol@dancol.org>
1899 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
1900 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
1901 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
1902 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
1903 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
1904 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
1905 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
1906 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
1907 now a supported configuration.
1909 * Makefile.in: consolidate image variables into LIBIMAGE; add
1910 W32_OBJ and W32_LIBS. Compile new files.
1913 (_DebPrint) declare tracing facility for W32 debugging. We need
1914 to unify tracing later.
1916 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
1917 unconditional use of W32 Unicode functions. Cygwin runs only on
1918 100% Unicode operating systems.
1920 * cygw32.c: New file. Define Cygwin-specific facilities.
1921 (Fcygwin_convert_path_to_windows)
1922 (Fcygwin_convert_path_from_windows): New user functions for
1923 accessing Cygwin path-munging routines.
1925 * cygw32.h: New file.
1926 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
1927 UTF-16LE strings temporarily inside non-Lisp-visible string
1930 (w32_strerror): Just what it says on the tin.
1932 * emacs.c: Make the NS fork-then-exec code for daemon-launching
1933 also run for Cygwin; both systems have the same problem with using
1934 GUI facilities in a forked child. Also call syms_of_cygw32,
1935 syms_of_w32select in correct places.
1937 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
1938 needs fork-then-exec for daemon launching.
1940 * font.h: Include frame.h.
1942 * image.c: Use the image library cache machinery only when we're
1943 compiling for native WINDOWSNT; Cygwin can use shared libraries
1944 like any other Unixlike system.
1946 * keyboard.c: Clarify a comment regarding the input loop.
1948 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
1949 functions directly instead of trying to detect at runtime that our
1950 host operating system supports them. We make this change for two
1951 reasons: Cygwin lacks support for the multibyte character
1952 conversion functions used by the legacy menu code, and Cygwin
1953 never needs to rely on non-Unicode APIs.
1955 * unexw32.c (hinst): Declare extern.
1957 * w32.c: Change header order;
1958 (w32_strerror): Move to w32fns.c because we need it for
1959 non-WINDOWSNT builds.
1961 * w32.h: Add #error macro to make sure we don't include w32.h for
1962 Cygwin builds. Remove w32select declarations.
1964 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
1965 w32fns.c. w32console.c is WINDOWSNT-only.
1967 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
1968 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
1970 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
1971 (w32_major_version, w32_minor_version, w32_build_number)
1972 (os_subtype, sound_type): Define here
1973 (w32_defined_color): Make color parameter const for consistency
1974 with other _defined_color functions.
1975 (w32_createwindow): Unconditionally call w32_init_class instead of
1976 doing so only when hprevinst is non-NULL. Plumbing hprevinst
1977 through the code is complex and unnecessary because class
1978 registration is practically free.
1979 (w32_name_of_message): New EMACSDEBUG-only function.
1980 (Fset_message_beep): Move here
1981 (Fx_open_connection): Require that the display name for Windows be
1982 "w32" for consistency, emacsclient disambiguation, and maybe, one
1983 day, multi-window-system support.
1984 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
1985 Cygwin files for W32 GUI facilities, since these clearly don't
1986 expect Cygwin names.
1987 (_DebPrint): Define.
1988 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
1989 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
1990 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
1991 (w32_last_error): Remove.
1993 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
1995 * w32heap.c (syspage_mask): Declare here.
1996 (cache_system_info): Remove.
1998 * w32inevt.c (faked_key): Define globally, not statically.
1999 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
2000 (w32_console_toggle_lock_key): Move to w32fns.c.
2002 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
2004 * w32proc.c (_DebPrint): Move to w32fns.c.
2005 * w32select.c: Include string.h, stdio.h for Cygwin.
2006 * w32select.h: New File.
2008 * w32term.c: Include io.h for non-CYGWIN builds; needed for
2010 (w32_message_fd): New variable. Under Cygwin, holds the file
2011 descriptor the system used to tell us about pending thread
2014 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
2015 that prevented compilation under non-WINDOWSNT systems.
2017 (w32_initialize): Open /dev/windows and assign it to
2018 w32_message_fd. Provide w32 feature.
2020 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
2021 (WM_EMACS_INPUT_READY): add.
2022 (prepend_msg, w32_message_fd): Declare globally.
2025 (keyboard_handle): Use only when WINDOWSNT.
2026 (notify_msg_ready): New function. Posts a message to the main
2027 thread's message queue under CYGWIN, which wakes up the main
2028 thread from select(2) by making the /dev/windows file descriptor
2029 ready. Under WINDOWSNT, it sets an event the same way the old
2032 (post, prepend_msg): Actually call notify_msg_ready instead of
2033 setting the input event directly.
2035 2012-10-07 Eli Zaretskii <eliz@gnu.org>
2037 * ralloc.c (relinquish): If a heap is ready to be relinquished,
2038 but it still has blocs in it, don't return it to the system,
2039 instead of aborting. (Bug#12402)
2041 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
2043 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
2045 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
2046 MAC_OS_X_VERSION_10_6.
2047 (syms_of_nsterm): Remove comment about Panther and above for
2049 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
2050 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
2051 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
2053 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
2054 MAC_OS_X_VERSION_10_4.
2056 * nsmenu.m (fillWithWidgetValue:): Remove code for <
2057 MAC_OS_X_VERSION_10_2.
2059 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
2061 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
2062 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
2064 * nsterm.m (ns_in_resize): Remove (Bug#12479).
2065 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
2066 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
2067 Remove ns_in_resize check.
2068 (ns_clear_frame_area): Remove resize handle code.
2070 * nsfns.m (ns_in_resize): Remove.
2071 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
2072 Remove ns_in_resize check.
2074 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
2076 Improve sys_siglist detection.
2077 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
2078 defined as a macro, as is done in Solaris.
2079 (sys_siglist_entries): New macro.
2080 (save_strsignal): Use it.
2081 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
2082 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
2084 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
2086 * nsfns.m (Fx_create_frame): Call x_default_parameter with
2087 fullscreen/Fullscreen.
2089 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
2090 tobar_height is new.
2092 * nsterm.m (x_make_frame_visible): Check for fullscreen.
2093 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
2094 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
2095 (windowDidResize:): Check for correct window if old style fullscreen.
2096 Capitalize word in comment. Remove incorrect comment.
2097 (initFrameFromEmacs:): tbar_height renamed tibar_height.
2098 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
2099 error in drawing background.
2100 (toggleFullScreen:): Remove comment. Rearrange calls.
2101 Set toolbar values to zero, save old height in tobar_height.
2102 Restore tool bar height when leaving fullscreen.
2103 (canBecomeMainWindow): New function.
2105 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
2107 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
2109 2012-10-05 Eli Zaretskii <eliz@gnu.org>
2111 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
2113 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
2114 that time stamps of directories could also be changed.
2115 Don't request the too broad GENERIC_WRITE, only the more restrictive
2116 FILE_WRITE_ATTRIBUTES access rights.
2118 * fileio.c (Fset_file_times): Special-case ignoring errors for
2119 directories only on MSDOS, not on MS-Windows.
2121 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
2123 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
2125 2012-10-04 Eli Zaretskii <eliz@gnu.org>
2127 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
2128 see whether CreateFile failed.
2130 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
2132 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
2133 to avoid similar races.
2134 * keyboard.c (pending_signals): Now bool, not int.
2136 Port timers to OpenBSD, plus check for timer failures.
2137 OpenBSD problem reported by Han Boetes.
2138 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
2140 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
2141 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
2142 like OpenBSD, which has timer_settime but does not declare it.
2143 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
2144 whether to use itimerspec-related primitives. All uses of
2145 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
2147 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2149 * profiler.c (handle_profiler_signal): Fix a malloc race
2150 that caused Emacs to hang on Fedora 17 when profiling Lisp.
2152 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
2154 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
2156 2012-10-02 Eli Zaretskii <eliz@gnu.org>
2158 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
2159 consistent with the change in return value of 'safe_strsignal'.
2161 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2163 Prefer plain 'static' to 'static inline' (Bug#12541).
2164 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
2165 (bidi_set_sor_type, bidi_push_embedding_level)
2166 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
2167 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
2168 (bidi_cache_search, bidi_cache_ensure_space)
2169 (bidi_cache_iterator_state, bidi_cache_find)
2170 (bidi_peek_at_next_level, bidi_set_paragraph_end)
2171 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
2172 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
2173 Now 'static', not 'static inline'.
2175 Count overruns when profiling; change units to ns.
2176 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
2177 Give extra weight to samples after overruns, to attempt to count
2178 the time more accurately.
2179 (setup_cpu_timer): Change sampling interval units from ms to ns, since
2180 the underlying primitives nominally do ns.
2181 (Fprofiler_cpu_start): Document the change. Mention that
2182 the sampling intervals are only approximate.
2184 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
2186 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
2188 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
2189 case for the special 0 coding-system.
2191 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
2192 (Fmake_overlay): Remove redundant tests.
2193 (fix_start_end_in_overlays): Remove redundant recentering.
2195 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
2197 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
2198 Update dependencies.
2200 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2202 Fix a malloc race condition involving strsignal.
2203 A signal can arrive in the middle of a malloc, and Emacs's signal
2204 handler can invoke strsignal, which can invoke malloc, which is
2205 not portable. This race condition bug makes Emacs hang on GNU/Linux.
2206 Fix it by altering the signal handler so that it does not invoke
2208 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
2209 * process.c (status_message): Use const pointer, in case strsignal
2210 is #defined to safe_strsignal.
2211 * sysdep.c (sys_siglist, init_signals): Always define and
2212 initialize a substitute sys_siglist if the system does not define
2213 one, even if HAVE_STRSIGNAL.
2214 (safe_strsignal): Rename from strsignal. Always define,
2215 using sys_siglist. Return a const pointer.
2216 * syssignal.h (safe_strsignal): New decl.
2217 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
2219 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2221 * w32proc.c (timer_loop): Fix code that waits for timer
2222 expiration, to avoid high CPU usage.
2224 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
2226 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
2227 (sweep_weak_table): Remove redundant prototypes.
2229 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
2231 * emacs.c: Move the inclusion of TERM_HEADER after including
2232 windows.h on WINDOWSNT. This avoids compilation problems with
2235 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2237 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
2238 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
2239 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
2240 as the previous version used 'void *'.
2242 * ralloc.c (ROUNDUP): Fix last change.
2243 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
2246 * w32proc.c <disable_itimers>: New static flag.
2247 (init_timers): Initialize it to zero, after creating the critical
2248 sections used by the timer threads.
2249 (term_timers): Set to 1 before deleting the critical sections.
2250 (getitimer, setitimer): If disable_itimers is non-zero, return an
2251 error indication without doing anything. Reported by Fabrice
2252 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
2253 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
2255 [!HAVE_SETITIMER]: Behave as the previous version that didn't
2258 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
2259 term_ntproc after all the other bookkeeping, to get timers working
2260 as long as possible.
2262 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2264 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
2265 Suggested by Juri Linkov in
2266 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
2268 Prefer plain 'static' to 'static inline' (Bug#12541).
2269 With static functions, modern compilers inline pretty well by
2270 themselves; advice from programmers often hurts as much as it helps.
2271 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
2272 this change shrinks the text size of the Emacs executable by 1.1%
2273 without affecting CPU significantly in my benchmark.
2274 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

2572 for consistency with other handlers.
2573 (setup_cpu_timer): New function, with much of what used to be in

2575 Prefer timer_settime if available, and prefer
2576 thread cputime clocks, then process cputime clocks, then
2577 monotonic clocks, to the old realtime clock. Use make_timeval
2578 to round more-correctly when falling back to setitimer.
2579 (Fprofiler_cpu_start): Use it.
2580 (Fprofiler_cpu_stop): Prefer timer_settime if available.

2647 Since this stuff is now private to charset.c, there's no need for
2648 a public macro and no need to inline by hand.

2790 Use bool for booleans.
2792 2012-09-24 Chong Yidong <cyd@gnu.org>
2794 * chartab.c (Fset_char_table_default): Obsolete function removed.
2796 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
2798 Move pid_t related decls out of lisp.h.
2799 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
2800 (interruptible_wait_for_termination):
2801 Move these decls from lisp.h to syswait.h, since they use pid_t.
2802 Needed on FreeBSD; see Herbert J. Skuhra in
2803 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
2804 * callproc.c: Include syswait.h.

2824 Use bool for boolean.
2825 * gtkutil.c (xg_update_frame_menubar):
2826 * xmenu.c (update_frame_menubar):
2827 Return void, not int, since caller ignores return value.

2850 2012-09-23 Eli Zaretskii <eliz@gnu.org>
2852 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
2853 fatal_error_backtrace.
2855 * w32proc.c (sys_kill): Undo last change: don't do anything when
2856 invoked to deliver SIGABRT to our own process. This is now
2857 handled by emacs_raise.
2859 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
2861 * w32term.c (w32_read_socket): Remove leftover reference to
2862 interrupt_input_pending.
2864 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
2866 Do not use SA_NODEFER.
2867 Problem reported by Dani Moncayo in
2868 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
2870 * sysdep.c (emacs_abort): Do not reset signal handler.
2871 * emacs.c (terminate_due_to_signal): Reset signal handler here.
2872 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
2873 wanted even on POSIXish hosts, and it doesn't work on Windows.
2875 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
2877 * xterm.c (x_term_init): Call fixup_locale before and after calling
2878 gtk_init (Bug#12392).
2880 2012-09-23 Chong Yidong <cyd@gnu.org>
2882 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
2883 Vdynamic_library_alist.
2885 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
2886 (Fgnutls_available_p): Caller changed.
2888 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
2889 (Flibxml_parse_xml_region): Likewise.
2891 * dispextern.h (struct image_type): Remove arg from init function.
2893 * image.c (Finit_image_library, lookup_image_type)
2894 (define_image_type): Remove now-unneeded second arg.
2895 (init_xpm_functions, init_png_functions, init_jpeg_functions)
2896 (init_tiff_functions, init_gif_functions, init_svg_functions):
2897 Arglist and w32_delayed_load calling convention changed.
2898 (gs_type): Remove init_gs_functions; there is no such function.
2899 (valid_image_p, make_image): Fix caller to lookup_image_type.
2901 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
2903 Simplify and avoid signal-handling races (Bug#12471).
2905 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
2906 Avoid recursive loop if there's a fatal error in the function itself.
2907 * atimer.c (pending_atimers):
2908 * blockinput.h: Don't include "atimer.h"; no longer needed.
2909 (interrupt_input_pending): Remove. All uses removed.
2910 pending_signals now counts both atimers and ordinary interrupts.
2911 This is less racy than having three separate pending-signal flags.
2912 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
2914 Rename from their upper-case counterparts BLOCK_INPUT,
2915 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
2916 INPUT_BLOCKED_P, and turn into functions. All uses changed.
2917 This makes it easier to access volatile variables more accurately.
2918 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
2919 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
2920 that's more reliable if the code is buggy and sets
2921 interrupt_input_blocked to a negative value. All uses changed.
2922 * atimer.c (deliver_alarm_signal):
2923 Remove. No need to deliver this to the parent; any thread can
2924 handle this signal now. All uses replaced by underlying handler.
2925 * atimer.c (turn_on_atimers):
2926 * dispnew.c (handle_window_change_signal):
2927 * emacs.c (handle_danger_signal):
2928 * keyboard.c (kbd_buffer_get_event):
2929 Don't reestablish signal handler; not needed with sigaction.
2930 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
2932 Rework to avoid unnecessary accesses to volatile variables.
2933 (UNBLOCK_INPUT_TO): Now a function.
2934 (totally_unblock_input, unblock_input): New decls.
2935 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
2936 (init_data): Remove. Necessary stuff now done in init_signal.
2937 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
2938 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
2939 (fatal_error_code): Remove; no longer needed.
2940 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
2941 it doesn't always backtrace. All uses changed. No need to reset
2942 signal to default, since sigaction and/or die does that for us now.
2943 Use emacs_raise (FOO), not kill (getpid (), FOO).
2944 (main): Check more-accurately whether we're dumping.
2945 Move fatal-error setup to sysdep.c
2946 * floatfns.c: Do not include "syssignal.h"; no longer needed.
2947 * gtkutil.c (xg_get_file_name, xg_get_font):
2948 Remove no-longer-needed signal-mask manipulation.
2949 * keyboard.c, process.c (POLL_FOR_INPUT):
2950 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
2951 * keyboard.c (read_avail_input): Remove.
2952 All uses replaced by gobble_input.
2953 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
2954 (kbd_buffer_store_event_hold, gobble_input):
2955 (record_asynch_buffer_change) [USABLE_SIGIO]:
2956 (store_user_signal_events):
2957 No need to mess with signal mask.
2958 (gobble_input): If blocking input and there are terminals, simply
2959 set pending_signals to 1 and return. All hooks changed to not
2960 worry about whether input is blocked.
2961 (process_pending_signals): Clear pending_signals before processing
2962 them, in case a signal comes in while we're processing.
2963 By convention callers now test pending_signals before calling us.
2964 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
2965 New functions, to support changes to blockinput.h.
2966 (handle_input_available_signal): Now extern.
2967 (reinvoke_input_signal): Remove. All uses replaced by
2969 (quit_count): Now volatile, since a signal handler uses it.
2970 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
2971 All callers changed. Block SIGINT only if not already blocked.
2972 Clear sigmask reliably, even if Fsignal returns, which it can.
2973 Omit unnecessary accesses to volatile var.
2974 (quit_throw_to_read_char): No need to restore sigmask.
2975 * keyboard.c (gobble_input, handle_user_signal):
2976 * process.c (wait_reading_process_output):
2977 Call signal-handling code rather than killing ourselves.
2978 * lisp.h: Include <float.h>, for...
2979 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
2980 (pending_signals): Now volatile.
2981 (syms_of_data): Now const if IEEE floating point.
2982 (handle_input_available_signal) [USABLE_SIGIO]:
2983 (terminate_due_to_signal, record_child_status_change): New decls.
2984 * process.c (create_process): Avoid disaster if memory is exhausted
2985 while we're processing a vfork, by tightening the critical section
2987 (send_process_frame, process_sent_to, handle_pipe_signal)
2988 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
2990 (send_process): No need for setjmp/longjmp any more, since the
2991 SIGPIPE stuff is now gone. Instead, report an error if errno
2993 (record_child_status_change): Now extern. PID and W are now args.
2994 Return void, not bool. All callers changed.
2995 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
2996 Remove. All uses removed. This bug should be fixed now in a
2998 (wait_for_termination_1): Use waitpid rather than sigsuspend,
2999 and record the child status change directly. This avoids the
3000 need to futz with the signal mask.
3001 (process_fatal_action): Move here from emacs.c.
3002 (emacs_sigaction_flags): New function, containing
3003 much of what used to be in emacs_sigaction_init.
3004 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
3005 caught by emacs, to make races less likely.
3006 (deliver_process_signal): Rename from handle_on_main_thread.
3008 (BACKTRACE_LIMIT_MAX): Now at top level.
3009 (thread_backtrace_buffer, threadback_backtrace_pointers):
3011 (deliver_thread_signal, deliver_fatal_thread_signal):
3012 New functions, for more-accurate delivery of thread-specific signals.
3013 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
3014 (deliver_arith_signal): Handle in this thread, not
3015 in the main thread, since it's triggered by this thread.
3016 (maybe_fatal_sig): New function.
3017 (init_signals): New arg DUMPING so that we can be more accurate
3018 about whether we're dumping. Caller changed.
3019 Treat thread-specific signals differently from process-general signals.
3020 Block all signals while handling fatal error; that's safer.
3021 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
3023 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
3024 Ignore SIGPIPE unless batch.
3025 (emacs_backtrace): Output backtrace for the appropriate thread,
3026 which is not necessarily the main thread.
3027 * syssignal.h: Include <stdbool.h>.
3028 (emacs_raise): New macro.
3029 * xterm.c (x_connection_signal): Remove; no longer needed
3030 now that we use sigaction.
3031 (x_connection_closed): No need to mess with sigmask now.
3032 (x_initialize): No need to reset SIGPIPE handler here, since
3033 init_signals does this for us now.
3035 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3037 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
3038 background rect may be larger (Bug#12245).
3040 2012-09-23 Chong Yidong <cyd@gnu.org>
3042 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
3044 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3046 * .gdbinit: Just stop at fatal_error_backtrace.
3047 See Stefan Monnier's request in
3048 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
3049 Remove no-longer-used query of system type.
3051 2012-09-22 Chong Yidong <cyd@gnu.org>
3053 * search.c (Freplace_match): Doc fix (Bug#12325).
3055 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
3057 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
3058 (Fline_end_position): Doc fix.
3060 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
3062 2012-09-22 Chong Yidong <cyd@gnu.org>
3064 * dispextern.h (struct image_type): Add new slot, storing a type
3065 initialization function.
3067 * image.c (define_image_type): Call the image initializer function
3068 if it is defined. Arguments and return value changed.
3069 (valid_image_p, make_image): Callers changed.
3070 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
3071 (gif_type, imagemagick_type, svg_type, gs_type):
3072 Add initialization functions.
3073 (Finit_image_library): Call lookup_image_type.
3074 (CHECK_LIB_AVAILABLE): Macro deleted.
3075 (lookup_image_type): Call define_image_type here, rather than via
3076 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
3077 (syms_of_image): Move define_image_type calls for xbm_type and
3078 pbm_type to lookup_image_type.
3080 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3082 * keyboard.c (timer_check_2): Move calculation of 'timers' and
3083 'idle_timers' from here ...
3084 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
3085 lists, to avoid infloops when the timer does something stupid,
3086 like reinvoke itself with the same or smaller time-out.
3089 2012-09-22 Martin Rudalics <rudalics@gmx.at>
3091 * window.c (Fsplit_window_internal): Handle only Qt value of
3092 Vwindow_combination_limit separately.

3104 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
3105 or that fprintf is async-signal-safe. POSIX doesn't require
3108 2012-09-22 Chong Yidong <cyd@gnu.org>
3110 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
3113 2012-09-22 Kenichi Handa <handa@gnu.org>
3115 * composite.c (composition_reseat_it): Handle the case that a
3116 grapheme cluster is not covered by a single font (Bug#12352).
3118 2012-09-21 Chong Yidong <cyd@gnu.org>
3120 * image.c (define_image_type): Avoid adding duplicate types to
3121 image_types (Bug#12463). Suggested by Jörg Walter.
3123 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3125 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.

3131 * eval.c (Frun_hook_with_args_until_success)
3132 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
3134 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
3136 * fileio.c (Ffile_selinux_context): Only call freecon when
3137 lgetfilecon succeeded.
3138 (Fset_file_selinux_context): Likewise. (Bug#12444)
3140 2012-09-21 Eli Zaretskii <eliz@gnu.org>
3142 * xdisp.c (try_window_reusing_current_matrix): Under bidi
3143 reordering, locate the cursor by calling set_cursor_from_row; if
3144 that fails, clear the desired glyph matrix before returning a
3145 failure indication to the caller. Fixes leaving garbled display
3146 when fast scrolling with a down-key. (Bug#12403)
3147 (compute_stop_pos_backwards): Fix a typo that caused crashes while
3148 scrolling through multibyte text.
3150 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
3152 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
3153 calling mark_vectorlike since that's the one that marks the window.
3154 (mark_discard_killed_buffers): Mark the final cdr.
3155 * window.h (struct window): Move prev/next_buffers to the
3156 non-standard fields.
3157 * window.c (make_window): Initialize prev/next_buffers manually.
3159 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
3161 Omit unused arg EXPECTED from socket hooks.
3162 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
3163 * nsterm.m (ns_term_init):
3164 * termhooks.h (struct terminal.read_socket_hook):
3165 * w32inevt.c (w32_console_read_socket):
3166 * w32term.c (w32_read_socket):
3167 * xterm.c (XTread_socket):
3168 Omit unused arg EXPECTED. All callers changed.
3169 (store_user_signal_events): Return void, not int, since callers no
3170 longer care about the return value. All uses changed.
3172 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
3174 * w32gui.h (XParseGeometry): Do not declare.
3176 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
3178 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
3179 Ignore 'expected'. See Eli Zaretskii in
3180 <http://bugs.gnu.org/12471#8> (last line).
3182 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
3183 (XParseGeometry): Now static. Substitute extremal values for
3184 values that are out of range.
3186 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
3188 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
3190 * nsfns.m (XParseGeometry): Remove.
3191 (Fx_create_frame): Call x_set_offset to correctly interpret
3192 top_pos in geometry.
3194 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
3195 (Fx_parse_geometry): If there is a space in string, call
3196 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
3198 2012-09-17 Eli Zaretskii <eliz@gnu.org>
3200 * search.c (scan_buffer): Use character positions in calls to
3201 region_cache_forward and region_cache_backward, not byte
3202 positions. (Bug#12196)
3204 * w32term.c (w32_read_socket): Set pending_signals to 1, like
3205 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
3207 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
3208 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
3209 emacs_blocked_malloc, now deleted.
3211 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
3213 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
3214 The workaround was for improving performance on Solaris 2.4, but
3215 is getting in the way now. Emacs will still work if someone is
3216 still running Solaris 2.4 in a museum somewhere; Sun dropped
3217 support for Solaris 2.4 in 2003.
3218 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
3219 * process.c (create_process) [HAVE_WORKING_VFORK]:
3220 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
3221 since Emacs no longer uses vfork on that platform.
3223 2012-09-17 Glenn Morris <rgm@gnu.org>
3225 * emacs.c: Use COPYRIGHT.
3227 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
3229 Remove configure's --without-sync-input option (Bug#12450).
3230 When auditing signal-handling in preparation for cleaning it up,
3231 I found that SYNC_INPUT has race conditions and would be a real
3232 pain to fix. Since it's an undocumented and deprecated
3233 configure-time option, now seems like a good time to remove it.
3234 Also see <http://bugs.gnu.org/11080#16>.
3235 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
3236 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
3237 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3238 (malloc_hysteresis):
3239 (check_depth) [XMALLOC_OVERRUN_CHECK]:
3240 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
3241 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
3242 (dont_register_blocks, bytes_used_when_reconsidered)
3243 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
3244 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
3245 [!SYSTEM_MALLOC && !SYNC_INPUT]:
3246 Remove. All uses removed.
3247 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
3248 implementation, one that depends on whether the new macro
3249 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
3251 * atimer.c (run_timers, handle_alarm_signal):
3252 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
3253 (handle_async_input, process_pending_signals)
3254 (handle_input_available_signal, init_keyboard):
3255 * nsterm.m (ns_read_socket):
3256 * process.c (wait_reading_process_output):
3257 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
3258 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
3260 * xterm.c (XTread_socket):
3262 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
3263 * eval.c (handling_signal): Remove. All uses removed.
3264 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
3265 All uses replaced with the SYNC_INPUT version.
3266 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
3268 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3271 * font.c (Ffont_shape_gstring): Remove unused local.
3273 2012-09-16 Glenn Morris <rgm@gnu.org>
3275 * Makefile.in (clean): No longer run nextstep's clean.
3277 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
3279 (ns-app): Move here from ns.mk, and simplify.
3280 (clean): Simplify nextstep entry.
3281 * ns.mk: Remove file.
3283 2012-09-17 Kenichi Handa <handa@gnu.org>
3285 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
3286 not covert the last few charactes.
3288 2012-09-16 Kenichi Handa <handa@gnu.org>
3290 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
3291 here, but just check the validity of glyphs in the glyph-string.
3293 2012-09-16 Martin Rudalics <rudalics@gmx.at>
3295 * window.c (Fwindow_parameter, Fset_window_parameter):
3296 Accept any window as argument (Bug#12452).
3298 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
3300 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
3301 to ns_term_init to avoid memory leak.
3303 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
3304 explicit retain/release.
3305 (ns_term_init): Only allow one display. Initialize outerpool and
3308 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3310 Port _setjmp fix to POSIXish hosts as well as Microsoft.
3311 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
3312 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
3313 the Microsoft problem in a different way, by altering ../nt/config.nt.
3315 2012-09-15 Eli Zaretskii <eliz@gnu.org>
3330 * w16select.c: Remove inclusion of setjmp.h, as it is now included
3331 by lisp.h. This completes removal of setjmp.h inclusion
3332 erroneously announced in the previous commit. (Bug#12446)
3334 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
3337 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
3338 not defined as a macro. The latter happens on MS-Windows.
3341 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3343 Port better to POSIX hosts lacking _setjmp (Bug#12446).
3344 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
3345 Some instances of '#include <setjmp.h>' removed, if the
3346 only reason for the instance was because "lisp.h" was included.
3347 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
3348 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
3349 and _longjmp with the new symbols. Emacs already uses _setjmp if
3350 available, so this change affects only POSIXish hosts that have
3351 sigsetjmp but not _setjmp, such as some versions of Solaris and
3352 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
3353 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
3354 (png_load_body) [HAVE_PNG]:
3355 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
3356 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
3357 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
3358 since PNG requires jmp_buf. This is the only exception to the
3359 general rule that we now use sys_setjmp and sys_longjmp.
3360 This exception is OK since this code does not change the signal
3361 mask or longjmp out of a signal handler.
3363 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
3365 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3366 Include "syssignal.h", for 'main_thread'.
3368 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
3370 Avoid out-of-range marker position (Bug#12426).
3371 * insdel.c (replace_range, replace_range_2):
3372 Adjust markers before overlays, as suggested by comments.
3373 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
3374 Remove redundant check before calling offset_intervals.
3376 2012-09-14 Martin Rudalics <rudalics@gmx.at>
3378 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
3379 current buffer (Bug#12387).
3381 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
3383 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
3385 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3387 Use a more backwards-compatible timer format (Bug#12430).
3388 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
3389 vector element, not from the 4th, since PSECS is now at the end.
3390 (Fcurrent_idle_time): Doc fix.
3392 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
3394 Function to mark objects and remove killed buffers at once.
3395 * alloc.c (discard_killed_buffers): Rename to ...
3396 (mark_discard_killed buffers) ... new name. Add marking
3397 of remaining objects. Fix comment. Adjust users.
3398 (mark_object): Do not touch frame buffer lists here.
3399 * frame.c (delete_frame): Reset frame buffer lists here.
3401 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3403 Better workaround for GNOME bug when --enable-gcc-warnings.
3404 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
3405 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
3406 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
3408 Simplify SIGIO usage (Bug#12408).
3409 The code that dealt with SIGIO was crufty and confusing, e.g., it
3410 played tricks like "#undef SIGIO" but these tricks were not used
3411 consistently. Simplify mostly by not #undeffing standard symbols,
3412 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
3413 or not as we please) rather than "defined SIGIO" (standard symbol
3414 that we probably shouldn't #undef).
3415 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
3416 Modules that need it can include it.
3417 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
3418 * dispextern.h (ignore_sigio): New decl.
3419 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
3420 unconditionally, since it's now a no-op if !USABLE_SIGIO.
3421 * emacs.c (shut_down_emacs):
3422 * keyboard.c (kbd_buffer_store_event_hold):
3423 Use ignore_sigio rather than invoking 'signal' directly.
3424 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
3426 (FIONREAD, SIGIO): Do not #undef.
3427 (tty_read_avail_input): Use #error rather than a syntax error.
3428 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
3429 for I_PIPE, used by SETUP_SLAVE_PTY.
3430 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
3431 * sysdep.c (croak): Remove; no longer needed. This bit of
3432 temporary code, with Fred N. Fish's comment that it's temporary,
3433 has been in Emacs since at least 1992!
3434 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
3435 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
3436 * syssignal.h (croak): Remove decl.
3437 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
3438 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
3439 now that we're termios-only.
3440 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
3441 * term.c (dissociate_if_controlling_tty): Use #error rather than
3444 Work around GCC and GNOME bugs when --enable-gcc-warnings.
3445 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
3446 to work around GNOME bug 683906.
3447 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
3448 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
3449 This works around GCC bug 54561.
3451 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
3453 More fixes for 'volatile' and setjmp/longjmp.
3454 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
3455 * image.c (struct png_load_context) [HAVE_PNG]: New type.
3456 (png_load_body) [HAVE_PNG]:
3457 (jpeg_load_body) [HAVE_JPEG]:
3458 New function, with most of the old parent function's body.
3459 (png_load) [HAVE_PNG]:
3460 (jpeg_load) [HAVE_JPEG]:
3461 Invoke the new function, to avoid longjmp munging our locals.
3462 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
3463 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
3464 longjmp is passed 2, as the C standard doesn't guarantee this.
3465 Instead, store the failure code into mgr->failure_code.
3467 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
3469 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
3470 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
3471 (syms_of_keyboard): Remove support for unread-command-char.
3473 2012-09-12 Eli Zaretskii <eliz@gnu.org>
3475 * w32proc.c (sys_kill): If PID is our process ID and the signal is
3476 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
3477 violation. (Bug#12426)
3479 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
3481 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
3483 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
3485 * eval.c: Add `inhibit-debugger'.
3486 (Qinhibit_debugger): New symbol.
3487 (call_debugger): Bind it instead of Qdebug_on_error.
3488 (maybe_call_debugger): Test Vinhibit_debugger.
3489 (syms_of_eval): Define inhibit-debugger.
3490 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
3491 (syms_of_xdisp): Remove inhibit-debug-on-message.
3493 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
3495 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
3496 If a nonvolatile local variable is written before a _longjmp to
3497 the frame containing the variable, and is read after the _longjmp,
3498 the value read is indeterminate. Some local variables of type
3499 'struct handler' and 'struct catchtag' are used in this way, so
3500 mark each of their slots as volatile if the slot can be set before
3501 _longjmp and read afterwards.
3502 * lisp.h (struct handler): var and chosen_clause are now volatile.
3503 (struct catchtag): val, next, and pdlcount are now volatile.
3505 * bidi.c (bidi_push_it, bidi_pop_it):
3506 * fns.c (copy_hash_table):
3507 * image.c (define_image_type):
3508 * keyboard.c (kbd_buffer_store_event_hold):
3509 * process.c (Fprocess_send_eof):
3510 * xfaces.c (x_create_gc) [HAVE_NS]:
3511 * xgselect.c (xg_select):
3512 Prefer assignment to memcpy when either will do.
3514 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
3515 Use pointer-to-a-pointer to simplify and avoid a NILP check each
3516 time an item is removed. No need to mark this function 'inline';
3517 the compiler knows better than we do.
3519 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
3521 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
3522 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
3523 to change_frame_size (Bug#12388).
3524 (windowDidResize:): Pass YES to updateFrameSize.
3526 * nsterm.h: Add delay parameter to updateFrameSize.
3528 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
3530 Discard killed buffers from deleted window and frame objects.
3531 This reduces an amount of references to killed buffers and
3532 helps GC to reclaim them faster.
3533 * alloc.c (discard_killed_buffers): New function.
3534 (mark_object): Use it for deleted windows and frames.
3535 (mark_object): If symbol's value is set up for a killed buffer
3536 or deleted frame, restore its global binding.
3537 * data.c (swap_in_global_binding): Add GC notice.
3538 (swap_in_symval_forwarding): Use convenient set_blv_where.
3539 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
3540 * window.h: ... to here.
3542 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
3544 Convenient macro to check whether the buffer is live.
3545 * buffer.h (BUFFER_LIVE_P): New macro.
3546 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
3547 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
3549 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3551 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
3552 composition cases (Bug#12364).
3554 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
3555 overhang of succeeding glyphs overlapping box cursor.
3557 * w32term.c (x_draw_glyph_string): Likewise.
3559 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
3561 Simplify, document, and port floating-point (Bug#12381).
3562 The porting part of this patch fixes bugs on non-IEEE platforms
3563 with frexp, ldexp, logb.
3564 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
3566 * floatfns.c: Simplify discussion of functions that Emacs doesn't
3567 support, by removing commented-out code and briefly listing the
3568 C89 functions excluded. The commented-out stuff was confusing
3569 maintenance, e.g., we thought we needed cbrt but it was commented out.
3570 (logb): Remove decl; no longer needed.
3571 (isfinite): New macro, if not already supplied.
3572 (isnan): Don't replace any existing macro.
3573 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
3574 are present on all C89 platforms.
3575 (Ffrexp): Do not special-case zero, as frexp does the right thing
3577 (Flogb): Do not use logb, as it doesn't have the desired meaning
3578 on hosts that use non-base-2 floating point. Instead, stick with
3579 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
3580 frexp, to avoid getting an unspecified result.
3582 * xdisp.c (Qinhibit_debug_on_message): Now static.
3584 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
3586 * nsterm.m (ns_update_begin): Set clip path to whole view by using
3587 NSBezierPath (Bug#12131).
3589 2012-09-10 Chong Yidong <cyd@gnu.org>
3591 * fns.c (Fdelq, Fdelete): Doc fix.
3593 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
3595 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
3596 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
3598 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
3600 * lisp.h (make_lisp_ptr): New macro to replace XSET.
3601 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
3604 2012-09-09 Eli Zaretskii <eliz@gnu.org>
3606 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
3607 left fringe if the window has a left margin. This avoids leaving
3608 traces of the cursor because its leftmost pixel is not drawn over.
3610 * dispnew.c (update_window_line): When the left margin area of a
3611 screen line is updated, set the redraw_fringe_bitmaps_p flag of
3612 that screen line. (Bug#12277)
3614 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
3616 Assume C89 or later for math functions (Bug#12381).
3617 This simplifies the code, and makes it a bit smaller and faster,
3618 and (most important) makes it easier to clean up signal handling
3619 since we can stop worring about floating-point exceptions in
3620 library code. That was a problem before C89, but the problem
3621 went away many years ago on all practical Emacs targets.
3622 * data.c, image.c, lread.c, print.c:
3623 Don't include <math.h>; no longer needed.
3624 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
3625 might be autoconfigured, as that never happens.
3627 * doprnt.c (DBL_MAX_10_EXP):
3628 * print.c (DBL_DIG):
3629 Remove. C89 or later always defines these.
3630 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
3631 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
3632 (arith_error, domain_error, domain_error2):
3633 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
3634 no longer needed -- we simply return what C returns. All uses removed.
3635 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
3637 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
3638 Remove. All uses expanded, as these macros are no longer used
3639 more than once and are now more trouble than they're worth.
3640 (Ftan): Use tan, not sin / cos.
3641 (Flogb): Assume C89 frexp.
3642 (fmod_float): Assume C89 fmod.
3643 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
3644 (init_floatfns): Remove. All uses removed.
3646 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3648 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
3649 compositeToPoint for OSX < 10.6 (Bug#12390).
3651 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
3653 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
3654 This produces more-accurate results.
3656 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3658 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
3659 changes (Bug#12088).
3661 2012-09-08 Chong Yidong <cyd@gnu.org>
3663 * syntax.c (Fstring_to_syntax): Doc fix.
3665 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3667 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
3668 in the internal border.
3669 (x_set_window_size): Remove static variables and their usage.
3670 (ns_redraw_scroll_bars): Fix NSTRACE arg.
3671 (ns_after_update_window_line, ns_draw_fringe_bitmap):
3672 Remove fringe/internal border adjustment (Bug#11052).
3673 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
3674 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
3675 (ns_fix_rect_ibw): Remove.
3676 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
3677 (ns_dumpglyphs_box_or_relief): Ditto.
3678 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
3680 (ns_dumpglyphs_image): Ditto.
3681 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
3683 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
3684 their usage. Add fringe_extended_p and its use as in other terms.
3685 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
3686 scroll bar was removed.
3687 (updateFrameSize): New function.
3688 (windowDidResize): Move code to updateFrameSize and call it.
3690 * nsterm.h (EmacsView): Add updateFrameSize.
3692 2012-09-07 Chong Yidong <cyd@gnu.org>
3694 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
3696 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
3698 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
3700 More signal-handler cleanup (Bug#12327).
3701 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
3702 Problem introduced when merging patches. Noted by Eli Zaretskii in
3703 <http://bugs.gnu.org/12327#67>.
3704 * floatfns.c: Comment fix.
3705 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
3706 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
3707 and anyway the declaration is harmless even if SIGDANGER is not defined.
3708 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
3709 defined BROKEN_FIONREAD). systty.h formerly did this, but other
3710 source files not surprisingly expected syssignal.h to define, or
3711 not define, SIGIO, and it's cleaner to do it that way, for consistency.
3712 Include <sys/ioctl.h>, for FIONREAD.
3713 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
3714 This eliminates a problem whereby other files mysteriously had
3715 to include "syssignal.h" before including "systty.h" if they
3716 wanted to use "#ifdef SIGIO".
3718 2012-09-07 Eli Zaretskii <eliz@gnu.org>
3720 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
3722 * w32.c (sigemptyset): Empty the set.
3723 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
3725 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
3727 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
3729 * alloc.c (mark_buffer): Revert unsafe marking optimization.
3730 (mark_object): Likewise for frame objects.
3732 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
3734 * syssignal.h (handle_on_main_thread): Always declare,
3735 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
3736 This ports to platforms without HAVE_PTHREAD.
3738 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
3740 Signal-handler cleanup (Bug#12327).
3741 Emacs's signal handlers were written in the old 4.2BSD style with
3742 sigblock and sigmask and so forth, and this led to some
3743 inefficiencies and confusion. Rewrite these to use
3744 pthread_sigmask etc. without copying signal sets around. Also,
3745 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
3746 'signal', and instead use functions that do not attempt to take
3747 over the system name space. This patch causes Emacs's text
3748 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
3749 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
3750 Do not include <signal.h> or "syssignal.h", as these
3751 modules do not use signals.
3752 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
3753 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
3754 Do not include <signal.h>, as "syssignal.h" does that for us now.
3755 * atimer.c (sigmask_atimers): New function.
3756 (block_atimers, unblock_atimers): New functions,
3757 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
3759 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
3760 no longer needed here.
3761 * emacs.c (main): Inspect existing signal handler with sigaction,
3762 so that there's no need to block and unblock SIGHUP.
3763 * sysdep.c (struct save_signal): New member 'action', replacing
3764 old member 'handler'.
3765 (save_signal_handlers, restore_signal_handlers):
3766 Use sigaction instead of 'signal' to save and restore.
3767 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
3768 New function. All users of 'signal' modified to use set_sighandler
3769 if they're writeonly, and to use sys_signal if they're read+write.
3770 (emacs_sigaction_init, forwarded_signal): New functions.
3771 (sys_signal): Remove. All uses replaced by calls to sigaction
3772 and emacs_sigaction_init, or by direct calls to 'signal'.
3773 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
3774 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
3775 all uses replaced by pthread_sigmask etc. calls.
3776 * syssignal.h: Include <signal.h>.
3777 (emacs_sigaction_init, forwarded_signal): New decls.
3778 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
3779 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
3780 (sigmask, sys_sigmask): Remove; no longer needed.
3781 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
3782 (sigblock, sigunblock, sigfree):
3783 (sigsetmask) [!defined sigsetmask]:
3784 Remove. All uses replaced by pthread_sigmask.
3785 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
3786 no longer need to be replaced, and its typical old uses
3787 are now done via emacs_sigaction_init and sigaction.
3788 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
3789 (sys_sigdel): Remove; unused.
3790 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
3792 2012-09-06 Eli Zaretskii <eliz@gnu.org>
3794 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
3795 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
3797 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
3799 Explicitly mark buffer_defaults and buffer_local_symbols.
3800 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
3801 mark_local_symbols here.
3802 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
3803 since special buffers aren't marked here any more.
3804 (allocate_buffer): Chain new buffer with all_buffers here...
3805 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
3807 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
3808 (syms_of_buffer): Remove staticpro of the above.
3809 (init_buffer_once): Set names for buffer_defaults and
3810 buffer_local_symbols.
3812 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
3814 Use bool for booleans in font-related modules.
3815 * font.c (font_intern_prop, font_style_to_value)
3816 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
3817 (generate_otf_features, font_check_otf_features, font_check_otf)
3818 (font_match_p, font_list_entities, font_at):
3819 * fontset.c (fontset_id_valid_p, reorder_font_vector
3820 (fontset_find_font, Fset_fontset_font)
3821 (face_suitable_for_char_p) [0]:
3822 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
3823 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
3824 (m17n_flt_initialized, ftfont_shape_by_flt):
3825 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
3826 * nsfont.m (nsfont_draw):
3827 * w32font.c (w32font_draw):
3828 * w32term.c (x_draw_glyphless_glyph_string_foreground):
3829 Use bool for booleans.
3830 * font.h: Adjust to above API changes.
3831 (struct font, struct font_driver, struct font_driver_list):
3832 Use bool for booleans.
3833 (struct font): Remove useless member encoding_type.
3835 * fontset.c, xftfont.c: Omit unnecessary static decls.
3837 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
3839 * alloc.c (mark_object): Revert window marking code
3840 since it's unsafe for the Fset_window_configuration.
3842 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
3844 Fix race conditions with signal handlers and errno (Bug#12327).
3845 Be more systematic about preserving errno whenever a signal
3846 handler returns, even if it's not in the main thread. Do this by
3847 renaming signal handlers to distinguish between signal delivery
3848 and signal handling. All uses changed.
3849 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
3850 * data.c (deliver_arith_signal): Rename from arith_error.
3851 * dispnew.c (deliver_window_change_signal): Rename from
3852 window_change_signal.
3853 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
3854 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
3855 * keyboard.c (deliver_input_available_signal): Rename from
3856 input_available_signal.
3857 (deliver_user_signal): Rename from handle_user_signal.
3858 (deliver_interrupt_signal): Rename from interrupt_signal.
3859 * process.c (deliver_pipe_signal): Rename from send_process_trap.
3860 (deliver_child_signal): Rename from sigchld_handler.
3861 * atimer.c (handle_alarm_signal):
3862 * data.c (handle_arith_signal):
3863 * dispnew.c (handle_window_change_signal):
3864 * emacs.c (handle_fatal_signal, handle_danger_signal):
3865 * keyboard.c (handle_input_available_signal):
3866 * keyboard.c (handle_user_signal, handle_interrupt_signal):
3867 * process.c (handle_pipe_signal, handle_child_signal):
3868 New functions, with the actual signal-handling code taken from the
3869 original respective signal handlers, sans the sporadic attempts to
3870 preserve errno, since that's now done by handle_on_main_thread.
3871 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
3872 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
3873 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3875 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3876 Move initialization of main_thread to sysdep.c's init_signals.
3877 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
3878 our usage, and simplifies the mainline code.
3879 (record_child_status_change): New static function, as a helper
3880 for handle_child_signal, and with most of the old child handler's
3882 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
3883 (handle_child_signal): Use the above.
3884 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3885 Moved here from emacs.c.
3886 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
3887 code moved here from emacs.c's main function.
3888 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
3889 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
3890 This lets callers save and restore errno properly.
3892 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3894 Remove redundant or unused things here and there.
3895 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
3896 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
3897 * editfns.c (Fcompare_buffer_substrings): Likewise.
3898 * frame.h (struct terminal, struct font_driver_list):
3899 Remove redundant declarations.
3900 * window.h (Qleft, Qright): Likewise.
3902 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3904 Do not mark objects from deleted buffers, windows and frames.
3905 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
3906 (mark_object): Likewise for windows and frames.
3908 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3910 * alloc.c (valid_lisp_object_p): Treat killed buffers,
3911 buffer_defaults and buffer_local_symbols as valid objects.
3912 Return special value to denote them.
3914 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
3916 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
3917 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
3918 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
3919 (file_name_absolute_p, Fsubstitute_in_file_name):
3920 (check_executable, check_writable, Ffile_accessible_directory_p)
3921 (Fset_file_selinux_context, Fdefault_file_modes)
3922 (Finsert_file_contents, choose_write_coding_system)
3923 (Fwrite_region, build_annotations, a_write, e_write)
3925 * filelock.c (boot_time_initialized, get_boot_time)
3926 (get_boot_time_1, lock_file_1, within_one_second):
3927 * floatfns.c (in_float):
3928 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
3929 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
3930 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
3931 * lisp.h (struct Lisp_Hash_Table.cmpfn):
3932 * window.c (compare_window_configurations):
3933 Use bool for booleans.
3934 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
3935 (Fdefault_file_modes): Now mode_t, not int, for modes.
3936 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
3937 (internal_delete_file): Now returns void, not a (boolean) int,
3938 since nobody was looking at the return value.
3939 * lisp.h, window.h: Adjust to above API changes.
3941 * xdisp.c (set_message): Simplify and reindent last change.
3943 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
3945 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
3947 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
3949 * eval.c (call_debugger): Make the function non-static so that we
3950 can call it from set_message.
3952 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
3953 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
3955 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3957 Give more-useful info on a fatal error (Bug#12328).
3958 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
3959 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
3960 of doing the work ourselves.
3961 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
3962 do most of the work.
3963 (fatal_error_backtrace): New function, taken from the guts
3964 of the old fatal_error_signal, but with a new option to output
3966 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
3967 info about the signal than just its number.
3968 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
3969 * sysdep.c: Include <execinfo.h>
3970 (emacs_backtrace): New function, taken partly from the previous
3971 code of the 'die' function.
3972 (emacs_abort): Call fatal_error_backtrace rather than abort.
3974 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
3976 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
3977 eager (load-time) macro-expansion.
3978 * lisp.mk (lisp): Add macroexp.
3980 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3982 Simplify redefinition of 'abort' (Bug#12316).
3983 Do not try to redefine the 'abort' function. Instead, redo
3984 the code so that it calls 'emacs_abort' rather than 'abort'.
3985 This removes the need for the NO_ABORT configure-time macro
3986 and makes it easier to change the abort code to do a backtrace.
3987 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
3988 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
3989 Remove; sysdep.c's emacs_abort now takes its place.
3990 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
3991 'abort' changed to use 'emacs_abort'.
3992 * msdos.c (dos_abort) [defined abort]: Remove; not used.
3993 (abort) [!defined abort]: Rename to ...
3994 (emacs_abort): ... new name.
3995 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
3996 the place of the old 'abort' in emacs.c.
3997 * w32.c, w32fns.c (abort): Do not #undef.
3998 * w32.c (emacs_abort): Rename from w32_abort.
4000 2012-09-04 Eli Zaretskii <eliz@gnu.org>
4002 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
4003 offsets[j].dv, since the y axis of the screen coordinates points
4004 down, while the y axis of the font definition coordinates points
4005 up. This fixes display of Arabic diacritics such as KASRA and
4006 KASRATAN. (Bug#11860)
4008 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4010 Be more systematic about _setjmp vs setjmp.
4011 * alloc.c (test_setjmp, mark_stack):
4012 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
4013 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
4014 (png_load, my_error_exit, jpeg_load):
4015 * process.c (send_process_trap, send_process):
4016 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
4017 The underscored versions are up to 30x faster on some hosts.
4018 Formerly, the code used setjmp+longjmp sometimes and
4019 _setjmp+_longjmp at other times, with no particular reason to
4020 prefer setjmp+longjmp.
4022 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
4024 Fix minor problem found by static checking.
4025 * buffer.c (Fdelete_all_overlays): Return nil.
4027 2012-09-03 Martin Rudalics <rudalics@gmx.at>
4029 * buffer.c (Fdelete_all_overlays): New function.
4031 2012-09-03 Chong Yidong <cyd@gnu.org>
4033 * gtkutil.c: Add extern decl for Qxft.
4035 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
4037 * emacs.c, eval.c: Use bool for boolean.
4038 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
4039 (malloc_using_checking) [DOUG_LEA_MALLOC]:
4040 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
4041 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
4042 (main, decode_env_path, Fdaemon_initialized):
4043 * eval.c (call_debugger, Finteractive_p, interactive_p):
4044 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
4045 (maybe_call_debugger, Fbacktrace):
4046 * process.c (read_process_output, exec_sentinel):
4047 Use bool for booleans.
4048 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
4049 All callers changed.
4050 * eval.c (interactive_p): Omit always-true boolean argument
4051 EXCLUDE_SUBRS_P. All callers changed.
4052 * dispextern.h, lisp.h: Reflect above API changes.
4053 * firstfile.c (dummy): Use the address of 'main', whose signature
4054 won't change, instead of the address of 'initialize', whose
4055 signature just changed from int to bool.
4056 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
4057 * msdos.c (fatal_error_in_progress): ... from here.
4058 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
4060 (redisplay_internal, unwind_redisplay): Simply clear
4061 REDISPLAYING_P when unwinding, instead of saving its previous,
4062 always-false value and then restoring it.
4064 Clean up some extern decls.
4065 Mostly, this hoists extern decls out of .c files and into .h files.
4066 That way, we're more likely to catch errors if the interfaces change.
4067 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
4068 declare xg_mark_data.
4069 * dispextern.h (x_frame_parm_handlers):
4071 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
4072 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
4073 (Qultra_bold, Qoblique, Qitalic):
4074 Move extern decl here from .c file.
4075 * alloc.c (xg_mark_data) [USE_GTK]:
4077 * eval.c (Qlexical_binding):
4078 * fns.c (time) [!HAVE_UNISTD_H]:
4079 * gtkutil.c (Qxft, Qnormal, Qextra_light, Qlight, Qsemi_light)
4080 (Qsemi_bold, Qbold, Qextra_bold, Qultra_bold, Qoblique, Qitalic):

4282 * lread.c (init_lread): For out-of-tree builds, only add the
4283 source directory's site-lisp dir to the load-path if it exists,
4284 consistent with in-tree builds. (Bug#12302)
4286 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

4531 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
4533 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
4534 as that's faster and simpler than static storage. Don't bother
4535 with the g_main_context_query overhead if g_main_context_pending
4536 says no events are pending.
4537 (gfds, gfds_size): Remove these static vars.
4538 (xgselect_initialize): Remove; no longer needed.
4539 All uses and decls removed.
4541 * emacs.c (fatal_error_signal_hook): Remove.
4542 All uses removed. This leftover from old code was always 0.
4544 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
4545 * casefiddle.c (casify_object, casify_region):
4546 * casetab.c (set_case_table):
4547 * category.c, category.h (word_boundary_p):
4548 * category.h (CHAR_HAS_CATEGORY):
4549 Use bool for booleans, instead of int.
4551 2012-08-25 Eli Zaretskii <eliz@gnu.org>
4553 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
4555 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
4557 On assertion failure, print backtrace if available.
4558 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
4559 (die) [ENABLE_CHECKING]: Print a backtrace if available.
4560 * Makefile.in (LIB_EXECINFO): New macro.
4563 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
4564 * bytecode.c (exec_byte_code):
4565 * callint.c (check_mark, Fcall_interactively):
4566 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
4567 (getenv_internal, sync_process_alive, call_process_exited):
4568 * lisp.h (USE_SAFE_ALLOCA):
4569 Use bool for booleans, instead of int.
4570 * lisp.h, process.h: Adjust prototypes to match above changes.
4571 * callint.c (Fcall_interactively): Don't assume the mark's
4572 offset fits in 'int'.
4574 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
4576 * buffer.c, buffer.h: Use bool for boolean.
4577 * buffer.c (reset_buffer_local_variables)
4578 (buffer_lisp_local_variables, Fset_buffer_modified_p)
4579 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
4580 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
4581 (overlay_touches_p, overlay_strings, Foverlay_put)
4582 (report_overlay_modification, call_overlay_mod_hooks):
4583 (mmap_enlarge, mmap_set_vars):
4584 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
4585 Use bool for booleans, instead of int.
4586 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
4587 since the 1-or-0 return value is always ignored anyway.
4588 (mmap_initialized_p):
4589 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
4590 * buffer.h, lisp.h: Adjust prototypes to match above changes.
4592 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
4594 * bidi.c: Use bool for boolean.
4595 This is a bit more readable, and makes the text segment of bidi.o
4596 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
4597 Presumably it's faster too.
4598 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
4600 (bidi_cache_find_level_change, bidi_cache_iterator_state)
4601 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
4602 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
4603 (bidi_explicit_dir_char, bidi_level_of_next_char)
4604 (bidi_find_other_level_edge, bidi_move_to_visually_next):
4605 Use bool for booleans, instead of int.
4606 * dispextern.h (bidi_init_it, bidi_paragraph_init)
4607 (bidi_unshelve_cache): Adjust decls to match code.
4609 2012-08-23 Martin Rudalics <rudalics@gmx.at>
4611 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
4614 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
4616 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
4617 * atimer.h: Include <stdbool.h>.
4619 2012-08-22 Dan Nicolaescu <dann@gnu.org>
4621 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
4622 compile time tests instead of run time tests on systems that do
4624 (FRAME_MAC_P): Remove leftover from deleted code.
4625 * frame.c (syms_of_frame): Remove leftover from deleted code.
4627 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
4629 * nsterm.m (insertText:): Don't clear modifiers if code is space.
4631 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
4633 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
4634 Otherwise, the compiler complains about (A?B:C) where B is void
4635 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
4636 (fontset_add): Return void, for FONTSET_ADD.
4638 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4640 * alloc.c: Use bool for booleans.
4641 (gc_in_progress, abort_on_gc)
4642 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
4643 (dont_register_blocks) [GC_MALLOC_CHECK]:
4644 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
4645 (check_string_bytes, make_specified_string, memory_full)
4646 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
4647 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
4648 (mark_stack, valid_pointer_p, make_pure_string)
4649 (Fgarbage_collect, survives_gc_p, gc_sweep):
4650 Use bool for booleans, instead of int.
4651 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
4652 Remove unused local.
4653 * alloc.c (PURE_POINTER_P):
4654 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
4655 * editfns.c (Fformat):
4656 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
4658 * fns.c (sweep_weak_table):
4659 * lisp.h (suppress_checking, push_message, survives_gc_p)
4660 (make_pure_string, gc_in_progress, abort_on_gc):
4661 * lread.c (readchar, read1):
4662 * print.c (Fprin1_to_string):
4663 * xdisp.c (push_message):
4664 Use bool for booleans affected directly or indirectly by
4667 Make recently-introduced setters macros.
4668 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
4669 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
4670 (set_fontset_default, set_fontset_fallback): Rename from their
4671 upper-case counterparts, and make them functions rather than macros.
4672 This is more consistent with the other recently-introduced setters.
4673 These don't need to be inline, since they're local.
4675 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
4677 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
4678 the loop (Bug#12247).
4680 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4682 * lisp.h (vcopy): Use memcpy rather than our own loop.
4683 This fixes a performance regression introduced by the recent
4684 addition of vcopy. This means 'vcopy' will need to be modified
4685 for a copying collector, but that's OK. Also, tighten the
4686 checking in the assertion.
4688 2012-08-21 Eli Zaretskii <eliz@gnu.org>
4690 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
4691 components for RTL text (Bug#11860). Adjust X-OFFSET of each
4692 non-base glyph for the width of the base character, according to
4693 what x_draw_composite_glyph_string_foreground expects.
4694 Generate WADJUST value according to composition_gstring_width's
4695 expectations, to produce correct width of the composed character.
4696 Reverse the sign of the DU offset produced by ScriptPlace.
4698 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4700 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
4702 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
4704 Avoid direct writes to contents member of struct Lisp_Vector.
4705 * lisp.h (vcopy): New function to copy data into vector.
4706 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
4707 * fns.c (Ffillarray): Use ASET.
4708 * keyboard.c (timer_check_2): Use AREF and ASET.
4709 (append_tool_bar_item, Frecent_keys): Use vcopy.
4710 * lread.c (read_vector): Use ASET.
4711 * msdos.c (Frecent_doskeys): Use vcopy.
4712 * xface.c (Finternal_copy_lisp_face): Use vcopy.
4713 (Finternal_merge_in_global_face): Use ASET and vcopy.

4719 the position of its buffer's point.
4720 (Fset_window_point): For the selected window always go in its
4721 buffer to the specified position.
4723 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
4725 Setter macros for fontsets.
4726 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
4727 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
4728 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
4731 2012-08-20 Glenn Morris <rgm@gnu.org>
4733 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
4734 Don't assume that `ln -f' works.
4736 2012-08-20 Eli Zaretskii <eliz@gnu.org>
4738 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
4739 and later about non-assignments with no effect. See discussion at
4740 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
4743 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
4745 Inline setter functions for Lisp_Objects slots of struct specbinding.
4746 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
4749 2012-08-20 Martin Rudalics <rudalics@gmx.at>
4751 * window.c (select_window): Always make selected window's buffer
4754 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
4756 Use AREF and ASET for docstrings of category tables.
4757 * category.h (CATEGORY_DOCSTRING): Use AREF.
4758 (SET_CATEGORY_DOCSTRING): Use ASET.
4759 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
4761 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
4763 Inline setter functions for hash table members.
4764 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
4765 (set_hash_hash, set_hash_index): Rename with _slot suffix.
4766 (set_hash_key_and_value, set_hash_index, set_hash_next)
4767 (set_hash_hash): New functions.
4768 * charset.c, fns.c: Adjust users.
4770 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
4772 Inline getter and setter functions for per-buffer values.
4773 * buffer.h (per_buffer_default, set_per_buffer_default)
4774 (per_buffer_value, set_per_buffer_value): New functions.
4775 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
4776 * buffer.c, data.c: Adjust users.
4778 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
4780 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
4782 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
4784 Rely on <config.h> + <unistd.h> to declare 'environ',
4785 as gnulib does this if the system doesn't.
4786 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
4787 Remove declaration. MS-Windows declares it on stdlib.h which is
4788 included by conf_post.h.
4789 * emacs.c (environ) [DOUG_LEA_MALLOC]:
4790 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
4791 * vm-limit.c: Include <unistd.h>, for 'environ'.
4793 * unexaix.c, unexcoff.c: Include "mem-limits.h".
4794 (start_of_data): Remove decl; mem-limits.h provides it.
4796 * xdisp.c (handle_invisible_prop): Make it a bit faster
4797 and avoid a gcc -Wmaybe-uninitialized diagnostic.
4799 2012-08-19 Chong Yidong <cyd@gnu.org>
4801 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
4804 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
4806 * .gdbinit: Use call instead of set when calling a function in the
4809 * data.c (set_internal): Don't use set_blv_found.
4810 (Fkill_local_variable): Likewise.
4812 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
4814 * nsfont.m (ns_ascii_average_width): Ensure the string
4815 ascii_printable is initialized with a null-terminated character
4816 array. Otherwise, it can contain undesired extra characters.
4818 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
4820 port new setting code to Sun C 5.8 2005/10/13
4821 * chartab.c, lisp.h (char_table_set, char_table_set_range):
4822 Return void, not Lisp_Object. Otherwise, the compiler
4823 complains about (A?B:C) where B is void and C is Lisp_Object
4824 when compiling CHAR_TABLE_SET, due to the recent change to
4825 the API of sub_char_table_set_contents.
4827 2012-08-18 Chong Yidong <cyd@gnu.org>
4829 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
4830 for the string case (Bug#3874).
4832 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
4834 * buffer.h (BSET): Remove (Bug#12215).

4913 are compiled into code.
4914 (tset_param_alist): New setter function.
4916 2012-08-17 Paul Eggert <eggert@cs.ucla.edu>
4918 * keyboard.h (KSET): Remove (Bug#12215).

5657 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
5658 * w32.c (init_environment): Change the default values of many
5659 environment variables in dflt_envvars[] to NULL, to avoid pushing
5660 them into environment when they were not already defined.
5661 Remove the code that deletes site-lisp subdirectories from the default
5662 value of EMACSLOADPATH, as it is no longer needed.
5663 (check_windows_init_file): Now external, not static.
5664 Use Vload_path as is, without adding anything, as this function is now
5665 called when Vload_path is already set up.
5667 * w32.h (check_windows_init_file): Add prototype.
5669 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

5713 Remove unnecessary pointer casts.
5714 * alloc.c (record_xmalloc): New function.
5715 * lisp.h (record_xmalloc): New decl.
5716 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
5717 more like a function. This is because the pointer cast is not
5718 needed. All uses changed.
5719 * print.c (print_string, print_error_message): Avoid length recalc.
5721 Improve fix for macroexp crash with debugging (Bug#12118).
5722 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
5723 ARRAY_MARK_FLAG when checking subscripts, because ASET is
5724 not supposed to be invoked from the garbage collector.

5726 (gc_aset): New function, which is like ASET but can be
5727 used in the garbage collector.

5756 with addition of handling of symlinks and support for 'lstat'.
5757 If possible, get file's attributes and security information by
5758 handle, not by name. Produce S_IFLNK bit for symlinks, when
5759 called from 'lstat'.
5760 (stat, lstat): New functions, call 'stat_worker'.
5761 (symlink, readlink, careadlinkat): Rewritten to create and resolve
5762 symlinks when the underlying filesystem supports them.
5764 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
5766 Fix macroexp crash on Windows with debugging (Bug#12118).
5767 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
5768 checking subscripts; problem introduced with the recent
5769 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
5770 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
5771 since it's used in non-static inline functions now.
5773 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
5774 Don't assume buffer size fits in 'int'. Remove unused local.

5795 * dispnew.c (DISPEXTERN_INLINE):
5796 * sysdep.c (SYSTIME_INLINE):
5797 Define to EXTERN_INLINE, so that the corresponding functions
5798 are compiled into code.
5799 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
5800 (INLINE_HEADER_END): New macros.
5801 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

5821 hard-coding the path separator.
5823 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
5825 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
5826 This how ASET and AREF are supposed to work, and makes
5827 it easier to think about future improvements. See
5828 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
5829 * charset.h (set_charset_attr): New function.

6298 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
6300 Fast save_excursion_save and save_excursion_restore.
6301 * lisp.h (struct Lisp_Excursion): New data type.
6302 (PVEC_EXCURSION): New pseudovector type.
6303 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
6304 to deal with it. Adjust comments.
6305 (init_marker, attach_marker): New prototype.
6306 (unchain_marker): Adjust prototype.

6318 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
6319 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
6320 emacs.c, as this is a more-suitable home. Had this been done earlier
6321 the fix for 12036 would have avoided some of the problems noted in
6322 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
6323 would have been more obvious.
6324 * emacs.c: Do not include <verify.h>; no longer needed.
6325 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
6326 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
6327 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
6328 Remove; now done in lisp.h.
6329 * lisp.h (PUBLISH_TO_GDB): New macro.

6333 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
6334 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
6335 not be usable in #if. This simplifies things.
6337 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
6339 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
6341 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

6344 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
6345 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
6346 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
6347 Adjust to changes in lisp.h and emacs.c, by using
6348 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
6349 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
6350 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
6351 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
6352 instead of gdb_valbits.
6353 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
6354 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
6355 instead of gdb_array_mark_flag.
6356 (xboolvector): Get size from $->size, not $->header.size.
6357 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
6358 (xreload, hook-run, hookpost-run): Remove.
6359 * emacs.c: Include <verify.h>.
6360 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
6361 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
6363 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
6364 (gdb_USE_LSB_TAG): New enum constants.
6365 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
6366 Also define these as enum constants, so they're visible to GDB.
6367 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
6368 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
6369 as constants, so they're visible to GDB.

6371 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
6372 Now enum constants, not macros, so they're visible to GDB.
6373 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
6374 more convenient now. All uses changed.
6375 (VALMASK) [USE_LSB_TAG]: Also define in this case.
6376 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
6378 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

6385 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
6386 add argument, tune behavior, and adjust all callers.
6388 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
6390 Use typedef for EMACS_INT, EMACS_UINT.
6391 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
6392 than macros. This simplifies debugging in the usual case, since
6393 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
6394 and it allows expressions involving EMACS_INT casts.
6395 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
6397 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

6409 Adjust buffer text indirection counters at the end of Fkill_buffer.
6410 * buffer.c (Fkill_buffer): Adjust indirection counters when the
6411 buffer is definitely dead. This should really fix an issue reported
6412 by Christoph Scholtes again. (Bug#12007).
6413 (init_buffer_once): Initialize indirection counters of
6414 buffer_defaults and buffer_local_symbols (for sanity and safety).
6416 2012-07-24 Eli Zaretskii <eliz@gnu.org>
6418 * xdisp.c (init_iterator): Don't compute dimensions of truncation
6419 and continuation glyphs on tooltip frames, leave them at zero.

6447 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
6449 Swap buffer text indirection counters in Fbuffer_swap_text.
6450 * buffer.c (Fbuffer_swap_text): Swap indirections too.
6451 This avoids crash reported by Christoph Scholtes at
6452 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
6454 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
6456 * nsmenu.m (Popdown_data): New struct.

6479 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
6481 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
6482 as it's limited by the amount of memory, not by INT_MAX.
6484 2012-07-21 Eli Zaretskii <eliz@gnu.org>
6486 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
6487 in special-event-map. See the discussion at

6637 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
6639 * eval.c (Fdefvar): Don't check constants since we only set the var if
6640 it's not yet defined anyway (bug#11904).
6642 * lisp.h (last_undo_boundary): Declare new var.
6643 * keyboard.c (command_loop_1): Set it.
6644 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
6645 were auto-added by the command loop (bug#11774).

7194 Change to return ptrdiff_t.
7195 (xfont_list_pattern, xfont_match): Use length returned by
7196 xfont_decode_coding_xlfd.
7197 * xfns.c (x_default_font_parameter): Omit useless xstrdup.
7199 2012-07-11 Glenn Morris <rgm@gnu.org>

7202 Move DONT_REOPEN_PTY to configure.
7204 * sound.c (DEFAULT_SOUND_DEVICE) [!WINDOWSNT]:
7205 * s/netbsd.h (DEFAULT_SOUND_DEVICE): Let configure set it.
7207 2012-07-10 Paul Eggert <eggert@cs.ucla.edu>
7209 Remove "#define unix" that is no longer needed (Bug#11905).
7210 * s/aix4-2.h (unix): Remove; no longer needed.
7212 EMACS_TIME simplification (Bug#11875).
7213 This replaces macros (which typically do not work in GDB)
7214 with functions, typedefs and enums, making the code easier to debug.
7215 The functional style also makes code easier to read and maintain.
7216 * systime.h: Include <sys/time.h> on all hosts, not just if
7217 WINDOWSNT, since 'struct timeval' is needed in general.
7218 (EMACS_TIME): Now a typedef, not a macro.
7219 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
7221 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)
7222 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE, EMACS_TIME_EQ)
7223 (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE, EMACS_TIME_LT)
7224 (EMACS_TIME_LE): Now functions, not macros.
7225 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
7226 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
7227 which are not functions. All uses rewritten to use:
7228 (make_emacs_time): New function.
7229 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
7230 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
7231 not functions. All uses rewritten to use the following, respectively:
7232 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
7233 (add_emacs_time, sub_emacs_time): New functions.
7234 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
7235 * fileio.c (Fcopy_file):
7236 * xterm.c (XTflash): Get the current time closer to when it's used.
7237 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

7243 * fileio.c (Ffile_name_directory, Fsubstitute_in_file_name):
7244 * frame.c (Fmake_terminal_frame):
7245 * gtkutil.c (get_utf8_string):
7247 * nsmenu.m (ns_update_menubar):
7248 * regex.c (regerror):
7249 Prefer memcpy to strncpy and strncat when either will do.
7250 * fileio.c (Fsubstitute_in_file_name):
7251 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
7252 (menu_separator_name_p):
7253 * nsmenu.m (ns_update_menubar):
7254 Prefer memcmp to strncmp when either will do.
7255 * nsterm.m: Include <ftoastr.h>.
7257 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
7258 Prefer snprintf to strncpy.
7259 * nsterm.m (ns_term_init):
7260 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
7261 * nsterm.m (ns_term_init):
7262 Avoid the need for strncpy, by using build_string or
7263 make_unibyte_string directly. Use dtoastr, not snprintf.
7264 * process.c (Fmake_network_process): Diagnose service names that
7265 are too long, rather than silently truncating them or creating
7266 non-null-terminated names.
7267 (Fnetwork_interface_info): Likewise, for interface names.
7268 * sysdep.c (system_process_attributes) [GNU_LINUX]:
7269 Prefer sprintf to strncat.
7270 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
7271 Prefer vsnprintf to vsprintf + strncpy.
7273 2012-07-10 Glenn Morris <rgm@gnu.org>
7275 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
7276 Clarify fallback case.
7278 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
7280 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
7281 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
7282 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
7283 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
7284 where argument type is known to be a Lisp_Cons.
7286 2012-07-10 Tom Tromey <tromey@redhat.com>
7288 * bytecode.c (BYTE_CODE_THREADED): New macro.
7289 (BYTE_CODES): New macro. Replaces all old byte-code defines.
7290 (enum byte_code_op): New type.
7291 (CASE, NEXT, FIRST, CASE_DEFAULT, CASE_ABORT): New macros.

7294 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
7296 Optimize pure C strings initialization.
7297 * lisp.h (make_pure_string): Fix prototype.
7298 (build_pure_c_string): New function, defined as static inline. This
7299 provides a better opportunity to optimize away calls to strlen when
7300 the function is called with compile-time constant argument.
7301 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
7302 argument, adjust users accordingly. Use build_pure_c_string where
7304 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
7305 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
7306 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
7308 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
7310 Avoid calls to strlen in miscellaneous functions.
7311 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
7312 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
7313 * lread.c (openp): Likewise.
7315 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
7317 Avoid calls to strlen in path processing functions.
7318 * fileio.c (file_name_as_directory): Add comment. Change to add
7319 srclen argument and return the length of result. Adjust users
7321 (directory_file_name): Fix comment. Change to add srclen argument,
7322 swap 1st and 2nd arguments to obey the common convention.
7323 Adjust users accordingly.
7324 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
7326 2012-07-10 Glenn Morris <rgm@gnu.org>
7328 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
7329 Move PENDING_OUTPUT_COUNT definition to configure.
7331 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
7332 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
7333 * s/gnu.h (DATA_START): Move definitions to configure.
7335 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
7336 We include usg5-4-common.h, which defines them both.
7338 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
7339 O_RDONLY already includes it).
7341 Stop ns builds setting the EMACSLOADPATH environment variable.
7342 * nsterm.m (ns_load_path): Rename from ns_init_paths.
7343 Now it does not set EMACSLOADPATH, just returns the load-path string.
7344 * nsterm.h: Update accordingly.
7345 * lread.c [HAVE_NS]: Include nsterm.h.
7346 (init_lread) [HAVE_NS]: Use ns_load_path.
7347 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
7349 2012-07-09 Glenn Morris <rgm@gnu.org>
7351 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
7352 since the included bsd-common.h does so.
7354 Stop ns builds setting the EMACSPATH environment variable.
7355 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
7356 (ns_init_paths): Do not set EMACSPATH.
7357 * nsterm.h (ns_exec_path): Add it.
7358 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
7361 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
7363 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
7365 * process.c (wait_reading_process_output): 'waitchannels' was unset
7366 when read_kbd || !NILP (wait_for_cell); fix this.
7368 Add GCC-style 'const' attribute to functions that can use it.
7369 * character.h (char_resolve_modifier_mask):
7370 * keyboard.h (make_ctrl_char):
7371 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
7372 (init_character_once, next_almost_prime, init_fns, init_image)
7373 (flush_pending_output, init_sound):
7374 * mem-limits.h (start_of_data):
7375 * menu.h (finish_menu_items):
7376 Add ATTRIBUTE_CONST.

7378 Declare the dummy function with ATTRIBUTE_CONST.
7379 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
7380 Add decls with ATTRIBUTE_CONST.
7382 Minor improvements to make_formatted_string.
7383 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
7384 where int is good enough, as vsprintf returns an int.
7385 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
7387 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7389 Use make_formatted_string to avoid double length calculation.
7390 * lisp.h (make_formatted_string): New prototype.
7391 * alloc.c (make_formatted_string): New function.
7392 * buffer.c (Fgenerate_new_buffer_name): Use it.
7393 * dbusbind.c (syms_of_dbusbind): Likewise.

7395 * filelock.c (get_boot_time): Likewise.
7396 * frame.c (make_terminal_frame, set_term_frame_name)
7397 (x_report_frame_params): Likewise.
7398 * image.c (gs_load): Likewise.
7399 * minibuf.c (get_minibuffer): Likewise.
7400 * msdos.c (dos_set_window_size): Likewise.
7401 * process.c (make_process): Likewise.

7414 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7416 Move marker debugging code under MARKER_DEBUG.
7417 * marker.c (MARKER_DEBUG): Move marker debugging code under
7418 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
7419 for bootstrap with --enable-checking (~3x slowdown reported
7420 by Juanma Barranquero <lekktu@gmail.com>).
7421 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
7423 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
7425 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
7426 See <http://bugs.gnu.org/11825#29>.
7428 2012-07-08 Eli Zaretskii <eliz@gnu.org>
7430 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
7431 has no font, use the frame's font. (Bug#11813)
7432 (display_line): Add commentary about displaying truncation glyphs
7434 (produce_special_glyphs): Move here from term.c.
7436 * term.c (produce_special_glyphs): Move to xdisp.c.
7438 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
7441 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
7443 * xdisp.c (display_line): Avoid warning about implicit declaration
7446 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
7448 * lisp.h: Remove empty conditional.
7450 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
7452 * lread.c (load_path_check): Now static.
7454 Fix some minor --with-ns problems found by static checking.
7455 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
7456 (x_set_font) [!HAVE_X_WINDOWS]:
7457 * image.c (xpm_load_image) [HAVE_NS]:
7458 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
7459 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
7460 Remove unused local.
7461 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
7462 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
7463 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
7464 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
7465 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
7466 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
7467 Fix pointer signedness problem.
7468 * xfaces.c (FRAME_X_FONT_TABLE):
7469 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
7471 2012-07-07 Glenn Morris <rgm@gnu.org>
7473 * lread.c (load_path_check): New function, split from init_lread.
7474 (init_lread): Reorganize. Motivation:
7475 If EMACSLOADPATH is set, check/warn about that rather than the
7476 defaults, which we are not going to use. Hence we can remove
7477 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
7478 Don't warn if site-lisp directories are missing.
7479 If not installed, start from a blank load-path, since
7480 PATH_LOADSEARCH refers to the eventual installation directories.
7482 2012-07-07 Eli Zaretskii <eliz@gnu.org>
7484 Support truncation and continuation glyphs on GUI frames, when
7485 fringes are disabled. (Bug#11832)
7486 * xdisp.c (init_iterator): Get dimensions of truncation and
7487 continuation glyphs even if on GUI frames.
7488 Adjust it->last_visible_x on GUI frames when the left or right fringes,
7489 or both, are absent.
7490 (start_display, move_it_in_display_line_to): Handle the case of a
7491 GUI frame without a fringe to display continuation or truncation
7493 (insert_left_trunc_glyphs): Support GUI frames: make sure
7494 truncation glyphs overwrite enough glyphs from the current line to
7495 have sufficient space in pixels.
7496 (display_line): Support truncation and continuation glyphs on GUI
7497 frames. If some spare pixels are left on the line after inserting
7498 the truncation glyphs, fill that space with a stretch glyph of a
7499 suitably computed width.
7501 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
7502 produce_glyphs, to support GUI sessions.
7504 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
7506 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
7508 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
7510 Do not require float-time's arg to fit in time_t (Bug#11825).
7511 This works better on hosts where time_t is unsigned, and where
7512 float-time is applied to the (negative) difference between two times.
7513 * editfns.c (decode_time_components): Last arg is now double *,
7514 not int *, and means to store all the result as a double, without
7515 worrying about whether the seconds part fits in time_t.
7516 All callers changed.
7517 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
7518 All callers changed.
7519 (Ffloat_time): Do not fail merely because the specified time falls
7520 outside of time_t range.
7522 2012-07-07 Glenn Morris <rgm@gnu.org>
7524 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
7525 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):

7528 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
7530 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
7531 Update dependencies.
7533 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
7535 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7537 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
7538 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
7539 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
7540 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
7541 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
7542 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
7544 * xfont.c (compare_font_names): Redo to omit the need for casts.
7546 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
7548 * xfns.c (Fx_change_window_property): Doc fix.
7549 * w32fns.c (Fx_change_window_property): Doc fix.
7551 * w32fns.c (Fx_window_property): Accept the same arguments as the
7552 X Windows version. Doc fix.
7553 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
7555 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
7556 Eli Zaretskii <eliz@gnu.org>
7558 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
7559 Windows-specific code from nt/config.nt moved here.
7560 Obsolete settings removed.
7562 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7564 * process.c: Avoid unnecessary calls to gettime.
7565 (wait_reading_process_output): Don't get the time of day
7566 when gobbling data immediately and not waiting, as there's no need
7567 for it in that case. This removes a FIXME.
7569 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
7571 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
7572 is defined (Bug#11768).
7574 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7576 Fix marker debugging code.
7577 * marker.c (byte_char_debug_check): Do not perform the check
7578 if buffer is not multibyte.
7579 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
7580 Call byte_char_debug_check with correct arguments.
7582 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7584 Compile marker debugging code only if ENABLE_CHECKING is defined.
7585 * marker.c (byte_char_debug_check, count_markers):
7586 Use only if ENABLE_CHECKING is defined.
7587 (byte_debug_flag): Remove.
7588 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
7589 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
7591 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7593 Avoid code repetition in marker-related functions.
7594 * marker.c (attach_marker): New function.
7595 (Fset_marker, set_marker_restricted, set_marker_both)
7596 (set_marker_restricted_both): Use it.
7597 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
7598 Consistently rename charno to charpos.
7599 (marker_position): Add eassert.
7600 (marker_byte_position): Convert to eassert.

7619 * window.c (save_window_save): Likewise.
7621 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7623 Do not use Fdelete_overlay in delete_all_overlays
7624 to avoid redundant calls to unchain_overlay.
7625 * buffer.c (drop_overlay): New function.
7626 (delete_all_overlays, Fdelete_overlay): Use it.
7627 * minibuf.c (get_minibuffer): Fix comment.
7629 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7631 Port to OpenBSD 5.1 amd64.
7632 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
7633 This is needed for OpenBSD, and should be harmless on all BSD systems.
7634 Also, include <sys/sysctl.h>, as it should be available on all
7635 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
7636 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
7637 use p_pid member, not kp_proc.pid.
7639 2012-07-06 Glenn Morris <rgm@gnu.org>
7641 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
7643 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
7645 More xmalloc and related cleanup.
7646 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

7654 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
7656 Omit needless casts involving void * pointers and allocation.
7657 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
7658 as the former is more robust if P's type is changed.
7659 Prefer xzalloc to xmalloc + memset 0.
7660 Simplify malloc-or-realloc to realloc.
7661 Don't worry about xmalloc returning a null pointer.
7662 Prefer xstrdup to xmalloc + strcpy.
7663 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
7665 * keyboard.c (apply_modifiers_uncached): Prefer local array to
7666 alloca of a constant.
7668 2012-07-05 Eli Zaretskii <eliz@gnu.org>
7670 * xdisp.c (display_line): Fix horizontal pixel coordinates when
7671 hscroll is larger than the line width. Fixes long and futile
7672 looping inside extend_face_to_end_of_line (on a TTY) producing
7673 glyphs that are not needed and thrown away.
7675 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
7677 * marker.c (set_marker_restricted_both): Simplify by using

7687 not defined (Bug#11768).
7688 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
7689 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
7690 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
7691 followed by gtk_box_set_homogeneous (Bug#11768).
7692 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
7693 (update_theme_scrollbar_width, xg_create_scroll_bar):
7694 Use gtk_scrollbar_new (Bug#11768).
7695 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
7696 (is_box_type): New function (Bug#11768).

7703 * xdisp.c (window_hscroll_limited): New function.
7704 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
7705 coordinates when window's hscroll is set to insanely large
7708 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
7710 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

7771 * fileio.c (time_error_value): Check the right error number.
7772 Problem reported by Troels Nielsen in
7773 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
7775 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7777 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
7778 This should be fixed in a better way; see Eli Zaretskii in
7779 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
7780 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
7782 * fileio.c (time_error_value): Rename from special_mtime.
7783 The old name's problems were noted by Eli Zaretskii in
7784 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
7786 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
7787 This variable's comment says Emacs needs at least one GDB-visible
7788 symbol of type enum pvec_type, to work around GDB problems.
7789 The symbol's value doesn't matter.
7791 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
7792 that causes compilation to fail on pre-C99 compilers.
7794 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
7796 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
7797 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
7799 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
7801 * buffer.c (init_buffer_once): Fix initialization of
7802 headers for buffer_defaults and buffer_local_symbols.
7803 Reported by Juanma Barranquero <lekktu@gmail.com>.
7805 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
7807 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
7808 * lisp.h (enum pvec_type): Use fewer bits.
7809 (PSEUDOVECTOR_SIZE_BITS): New constant.
7810 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
7811 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
7812 change in pvec_type.
7813 (PSEUDOVECTOR_TYPEP): New macro.
7814 (TYPED_PSEUDOVECTORP): Use it.
7815 * fns.c (internal_equal): Adapt code to extract pvectype.
7816 * emacs.c (gdb_pvec_type): Update type.
7817 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
7818 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
7819 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
7820 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
7821 (sweep_vectors): Use it. Use local var `total_bytes' instead of
7822 abusing vector->header.next.nbytes.
7823 (live_vector_p): Use PVEC_TYPE.
7824 (mark_object): Adapt code to extract pvectype. Use switch.
7826 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7828 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
7829 Tighten new eassert a bit.
7831 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
7833 Fix compilation with --enable-gcc-warnings and -O1
7835 * doprnt.c (doprnt): Change type of tem to int, initialize
7836 to avoid compiler warning. Add eassert.
7837 * search.c (simple_search): Initialize match_byte to avoid
7838 compiler warning. Add eassert.
7840 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7842 Avoid weird behavior with large horizontal scrolls.
7843 Without this change, for example, large hscroll values would
7844 mess up Emacs's display on Fedora 15 x86, presumably due to
7845 overflows in int calculations in the display code.
7846 Also, if buffers had long lines, Emacs would freeze.
7847 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
7848 (set_window_hscroll): New function, containing the old guts of
7849 Fset_window_hscroll. Return the clipped value.
7850 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
7851 This avoids the need to check against PTRDIFF_MAX.
7853 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
7855 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
7857 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
7859 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7861 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
7862 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
7863 since GCC 4.4.6 issues a bogus warning for them.
7865 Fix bugs in file timestamp newness comparisons.
7866 * fileio.c (Ffile_newer_than_file_p):
7867 * lread.c (Fload): Use full timestamp resolution of files,
7868 not just the 1-second resolution, so that files that are only
7869 slightly newer still count as newer.
7870 * fileio.c (Ffile_newer_than_file_p): Don't assume file
7871 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
7873 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
7875 * fileio.c: Improve handling of file time marker. (Bug#11852)
7876 (special_mtime): New function.
7877 (Finsert_file_contents, Fverify_visited_file_modtime):
7878 Use it to set special mtime values consistently.
7880 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
7882 * fileio.c (Finsert_file_contents): Properly handle st_mtime
7883 marker for non-existing file. (Bug#11852)
7885 2012-07-03 Glenn Morris <rgm@gnu.org>
7887 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
7888 and did not make it into globals.h).
7890 2012-07-03 Tom Tromey <tromey@redhat.com>
7892 * window.c (Fset_window_margins, Fset_window_fringes)
7893 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
7894 * textprop.c (Fprevious_property_change): No longer static.
7895 * syntax.c (Fsyntax_table_p): No longer static.

7917 * intervals.h: Remove EXFUNs.
7918 * fontset.h: Remove EXFUN.

7923 * w32term.h: Remove EXFUNs.
7924 * window.h: Remove EXFUNs.
7925 * xsettings.h: Remove EXFUN.
7926 * xterm.h: Remove EXFUN.
7928 2012-07-03 Glenn Morris <rgm@gnu.org>
7930 * lisp.h (Frandom): Make it visible to C.
7931 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
7932 buffer for invisible buffers. (Bug#1229)
7934 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7936 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
7937 values which aren't power of 2.
7938 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
7939 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
7942 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
7944 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
7946 * alloc.c (mark_object): Revert part of last patch to use `switch'.
7948 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7950 * alloc.c (allocate_vector_block): Remove redundant
7951 calls to mallopt if DOUG_LEA_MALLOC is defined.
7952 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
7953 avoid calls to mallopt if zero_vector is returned.
7955 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7957 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
7958 is enabled, avoid dereferencing NULL current_sblock if
7961 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7963 Cleanup basic buffer management.
7964 * buffer.h (struct buffer): Change layout to use generic vector
7965 marking code. Fix some comments. Change type of 'clip_changed'
7966 to bitfield. Remove unused #ifndef old.
7967 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
7968 (GET_OVERLAYS_AT): Fix indentation.
7969 (for_each_per_buffer_object_at): New macro.
7970 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

7972 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
7973 * alloc.c (allocate_buffer): Adjust to match new layout of
7974 struct buffer. Fix comment.
7975 (mark_overlay): New function.
7976 (mark_buffer): Use it. Use mark_vectorlike to mark normal
7977 Lisp area of struct buffer.
7978 (mark_object): Use it. Adjust marking of misc objects
7979 and related comments.
7981 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
7983 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
7984 wrapper that is not needed because the wrapped code is a no-op (zero
7985 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
7986 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
7988 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
7990 * alloc.c (mark_buffer): Simplify. Remove prototype.
7991 (mark_object): Add comment. Reorganize marking of vector-like
7992 objects. Use CHECK_LIVE for all vector-like objects except buffers
7993 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
7994 Avoid redundant calls to mark_vectorlike for bool vectors.
7996 2012-06-30 Glenn Morris <rgm@gnu.org>
7998 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
8000 * epaths.in (PATH_SITELOADSEARCH): New.
8001 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
8002 This is rather than relying on --enable-locallisppath elements
8003 having "site-lisp" in their names. (Bug#10208#25, 11658)
8005 2012-06-30 Eli Zaretskii <eliz@gnu.org>
8007 * w32proc.c (sys_select): Accept and ignore one more argument.
8009 * w32.c (emacs_gnutls_pull): Call select with one more argument.
8011 * sysselect.h [DOS_NT]: Don't include sys/select.h.
8012 (pselect) [!MS_DOS]: Redirect to sys_select.
8014 * sysdep.c: Don't include dos.h and dosfns.h.
8016 * process.c (sys_select):
8017 * msdos.c (sys_select): Accept one more argument and ignore it.
8019 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
8020 adapt data types and code to that.
8023 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
8024 which clashes with the gnulib function of the same name.
8026 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
8028 * font.c (font_style_to_value, font_style_symbolic)
8029 (font_prop_validate_style): Add type checks for values in
8032 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
8034 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
8037 2012-06-29 Eli Zaretskii <eliz@gnu.org>
8039 * xdisp.c (try_window_id): Undo last change.
8041 * w32.c (getwd): Adjust commentary about startup_dir.
8042 (init_environment): Always call sys_access, even in non-MSVC
8043 builds. Don't chdir to the directory of the Emacs executable.
8044 This undoes code from 1997 which was justified by the need to
8045 "avoid conflicts when removing and renaming directories". But its
8046 downside was that every relative file name was being interpreted
8047 relative to the directory of the Emacs executable, which can never
8048 be TRT. In particular, it broke sys_access when called with
8049 relative file names.
8050 (sys_access): Map GetLastError to errno.
8052 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8054 * window.h (struct window): Change type of 'fringes_outside_margins'
8055 to bitfield. Fix comment. Adjust users accordingly.
8056 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
8058 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
8061 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
8063 * gnutls.c (emacs_gnutls_handshake):
8064 Add QUIT to make the loop interruptible.
8066 2012-06-29 Glenn Morris <rgm@gnu.org>
8068 * charset.c (init_charset): Make lack of etc/charsets fatal.
8070 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8072 * editfns.c (region_limit): Fix type mismatch.
8074 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8076 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
8077 undefined. Convert from xassert to eassert.
8078 * nsmenu.m: Convert from xassert to eassert.
8079 * nsterm.m: Likewise.
8081 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
8083 * editfns.c (region_limit): Clip to narrowing (bug#11770).
8085 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
8087 Avoid integer overflow on scroll-left and scroll-right.
8088 * window.c (HSCROLL_MAX): New macro.
8089 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
8090 overflow when requested scroll falls outside ptrdiff_t range.
8092 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8094 * window.h (struct window): Change type of 'hscroll',
8095 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
8096 'last_modified' and 'last_overlay_modified' to EMACS_INT.
8097 Adjust users accordingly.
8098 * xdisp.c (try_cursor_movement): Replace type check with eassert.
8099 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
8100 from EMACS_INT to ptrdiff_t.
8101 (make_window): Omit redundant initialization.
8103 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
8105 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
8107 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8109 * window.h (struct window): Change type of 'use_time' and

8244 Use sprintf return value instead of invoking strlen on result.
8245 In the old days this wasn't portable, since some sprintf
8246 implementations returned char *. But they died out years ago and
8247 Emacs already assumes sprintf returns int.
8248 Similarly for float_to_string.
8249 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

8258 * data.c (Fnumber_to_string):
8259 Use make_unibyte_string, since the string must be ASCII.
8260 * lisp.h, print.c (float_to_string): Now returns int length.
8261 * term.c (produce_glyphless_glyph):
8262 Use sprintf result rather than recomputing it.

8297 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

8433 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
8435 Support higher-resolution time stamps (Bug#9000).
8436 The time stamps are only nanosecond-resolution at the C level,
8437 since that's the best that any real-world system supports now.
8438 But they are picosecond-resolution at the Lisp level, as that's
8439 easy, and leaves room for future OS improvements.
8441 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
8444 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
8445 Don't get current time unless it's needed.
8447 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
8448 now provides it if it's absent.
8449 (start_atimer): Port to higher-res time stamps.
8450 Check for time stamp overflow. Don't get current time more
8451 often than is needed.
8453 * buffer.h (struct buffer): Buffer modtime now has high resolution.
8454 Include systime.h, not time.h.
8455 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
8457 * dired.c: Include stat-time.h.
8458 (Ffile-attributes): File times now have higher resolution.

8461 (struct image): Timestamp now has higher resolution.
8463 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
8464 has at least microseconds now. All uses removed.
8465 (update_frame, update_single_window, update_window, update_frame_1)
8466 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
8467 (duration_to_sec_usec): Remove; no longer needed.
8469 * editfns.c (time_overflow): Now extern.

8475 (decode_time_components, lisp_seconds_argument): New functions.
8476 (make_time): Now static.
8477 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
8478 Report an error if the time is invalid, rather than having the caller
8481 * fileio.c: Include <stat-time.h>
8482 (Fcopy_file): Copy higher-resolution time stamps.
8483 Prefer to set the time stamp via a file descriptor if that works.
8484 (Fset_file_times, Finsert_file_contents, Fwrite_region)
8485 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
8486 (Fvisited_file_modtime, Fset_visited_file_modtime):
8487 Support higher-resolution time stamps.
8489 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
8491 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
8493 * image.c (prepare_image_for_display, clear_image_cache)
8494 (lookup_image): Port to higer-resolution time stamps.
8496 * keyboard.c (start_polling, bind_polling_period):
8497 Check for time stamp overflow.
8498 (read_char, kbd_buffer_get_event, timer_start_idle)
8499 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
8500 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
8501 Port to higher-resolution time stamps. Do not assume time_t is signed.
8502 (decode_timer): New function. Timers are now vectors of length 9,
8503 not 8, to accommodate the picosecond component.
8504 (timer_check_2): Use it.
8506 * nsterm.m (select_timeout, timeval_subtract): Remove.
8507 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
8508 as they're a bit more accurate and handle overflow better.
8509 (ns_select): Change prototype to be compatible with pselect.
8510 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
8511 * nsterm.h (ns_select): Adjust prototype.
8513 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
8514 us-resolution time stamps.
8515 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
8517 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
8519 * lisp.h (time_overflow): New decl.
8520 (wait_reading_process_output): First arg is now intmax_t, not int,
8521 to accommodate larger waits.
8523 * process.h (struct Lisp_Process.read_output_delay):
8524 Now counts nanoseconds, not microseconds.
8525 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
8527 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
8528 (wait_reading_process_output):
8529 Port to ns-resolution time stamps.
8530 (Faccept_process_output, wait_reading_process_output):
8531 Check for time stamp overflow. Do not assume time_t is signed.
8532 (select_wrapper): Remove; we now use pselect.
8533 (Fprocess_attributes): Now generates ns-resolution time stamps.
8535 * sysdep.c: Include utimens.h. Don't include utime.h
8536 or worry about struct utimbuf; gnulib does that for us now.
8537 (gettimeofday): Remove; gnulib provides a substitute.
8538 (make_timeval): New function.
8539 (set_file_times): Now sets ns-resolution time stamps.
8540 New arg FD; all uses changed.
8541 (time_from_jiffies, ltime_from_jiffies, get_up_time)
8542 (system_process_attributes):
8543 Now returns ns-resolution time stamp. All uses changed.
8544 Check for time stamp overflow.
8546 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
8547 provides a substitute now.
8549 * systime.h: Include timespec.h rather than sys/time.h and time.h,
8550 since it guarantees struct timespec.
8551 (EMACS_TIME): Now struct timespec, so that we can support
8552 ns-resolution time stamps.
8553 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
8554 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
8555 (EMACS_USECS): Remove.
8556 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
8557 so multiply the arg by 1000 before storing it.
8558 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
8560 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
8561 Port to ns-resolution time stamps.
8562 (EMACS_TIME_NEG_P): Remove; replaced by....
8563 (EMACS_TIME_SIGN): New macro.
8564 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
8565 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.

8567 (make_timeval, make_lisp_time, decode_time_components): New decls.
8568 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
8569 that it mishandled time_t overflow. You can't compare by subtracting!
8570 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
8571 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
8573 * term.c: Include <sys/time.h>.
8574 (timeval_to_Time): New function, for proper overflow wraparound.
8575 (term_mouse_position, term_mouse_click): Use it.
8577 * undo.c (record_first_change): Support higher-resolution time stamps
8579 (Fprimitive_undo): Use them when restoring time stamps.
8581 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
8582 (w32_get_internal_run_time):
8583 Port to higher-resolution Emacs time stamps.
8584 (ltime): Now accepts single 64-bit integer, as that's more convenient
8587 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
8589 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
8590 for compatibility with pselect. Support ns-resolution time stamps.
8592 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.

8610 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
8611 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,

8663 gets killed during executing of this function (Bug#11665).
8664 Try to always return Qt when the buffer has been actually killed.

8666 run by this hook should not change the current buffer.
8668 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

8691 This removes the need for CHECK.
8692 (CHECK): Remove. Its comments about always evaluating its
8693 argument were confusing, as 'eassert' typically does not evaluate
8696 * coding.c (produce_chars): Use ptrdiff_t, not int.
8698 * xterm.c (x_draw_underwave): Check for integer overflow.
8699 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

8884 code works fine either way, and efficiency is not a concern here,
8885 as the union type is for debugging, not for production.
8886 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
8887 Use an inline function on all platforms when using the union type,
8888 since this is simpler and 'static inline' can be used portably

9003 Block-based vector allocation of small vectors.

9032 * doprnt.c (doprnt): Truncate multibyte char correctly.
9033 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
9034 would mishandle a string argument "Xc" if X was a multibyte
9035 character of length 2: it would truncate after X's first byte
9036 rather than including all of X.

9068 position is past the end of the mode line string.
9070 * buffer.c (buffer_local_value_1): New function, split from
9071 Fbuffer_local_value; can return Qunbound.
9072 (Fbuffer_local_value): Use it.

9079 2012-06-02 Stefan Monnier <monnier@iro.umontreal.ca>
9081 * keyboard.c: Export real-this-command to Elisp.
9082 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
9083 and DEFVAR it. Update all users.
9085 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
9087 * minibuf.c (Fassoc_string): Remove duplicate declaration.
9089 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
9090 Convert pctcpu and pctmem to Lisp float properly.
9091 Let the compiler fold better, as 100.0/0x8000 is exact.
9093 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
9095 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
9098 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
9100 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
9102 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
9104 For a 'struct window', replace some Lisp_Object fields to
9105 bitfields where appropriate, remove unused fields.
9106 * window.h (struct window): Remove unused 'last_mark_x' and
9107 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
9108 change its type from Lisp_Object to bitfield.
9109 Change type of 'force_start', 'optional_new_start',
9110 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
9111 fields from Lisp_Object to bitfield. Adjust users accordingly.
9113 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
9115 Pacify gcc -Wdouble-precision when using Xaw.
9116 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
9117 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
9118 Use 'float' consistently, rather than 'float' in most places
9119 and 'double' in a couple of places.
9121 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9123 * xdisp.c (handle_stop): Detect whether we have overlay strings
9124 loaded by testing it->current.overlay_string_index to be
9125 non-negative, instead of checking whether n_overlay_strings is
9126 positive. (Bug#11587)
9128 2012-05-31 Chong Yidong <cyd@gnu.org>
9130 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
9132 * doc.c (Fsubstitute_command_keys): Doc fix.
9134 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9136 * search.c (search_buffer): Remove calls to
9137 r_alloc_inhibit_buffer_relocation, as it is now called by
9138 maybe_unify_char, which was the cause of relocation of buffer text
9141 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9143 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
9144 for the duration of call to load_charset, to avoid problems with
9145 callers of maybe_unify_char that access buffer text through C
9148 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
9149 decrement the inhibition flag, instead of just setting or
9152 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
9154 Remove obsolete '#define static' cruft.
9155 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
9156 This #undef was "temporary" in 2000; it is no longer needed
9157 now that '#define static' has gone away.
9158 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
9159 (gray_bitmap_bits): Remove; no longer needed.
9160 All uses replaced with definiens.
9161 * xterm.c: Include "bitmaps/gray.xbm".
9163 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
9165 Clean up __executable_start, monstartup when --enable-profiling.
9166 The following changes affect the code only when profiling.
9167 * dispnew.c (__executable_start): Rename from safe_bcopy.
9168 Define only on platforms that need it.
9169 * emacs.c: Include <sys/gmon.h> when profiling.
9170 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
9171 (__executable_start): Remove decl, since lisp.h does it now.
9172 (safe_bcopy): Remove decl; no longer has that name.
9173 (main): Coalesce #if into single bit of code, for simplicity.
9174 Cast pointers to uintptr_t, since standard libraries want integers
9176 * lisp.h (__executable_start): New decl.
9178 2012-05-31 Glenn Morris <rgm@gnu.org>
9180 * image.c (Fimagemagick_types): Doc fix.
9182 2012-05-30 Jim Meyering <meyering@redhat.com>
9184 * callproc.c (Fcall_process_region): Include directory component
9185 in mkstemp error message (Bug#11586).
9187 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
9189 * alloc.c, lisp.h (make_pure_vector): Now static.
9191 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>

9196 * data.c (Fdefalias): Purify definition, except for keymaps.
9197 (Qdefun): Move from eval.c.
9198 * lisp.h (Qdefun): Remove.
9199 * lread.c (read1): Tiny simplification.
9201 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
9203 Do not create empty overlays with the evaporate property (Bug#9642).
9204 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
9205 Bug#9642, but explicitly check that the buffer the overlay would
9206 be moved to is live and rearrange lines to make sure that errors
9207 will not put the overlay in an inconsistent state.
9208 (Fdelete_overlay): Cosmetics.
9210 2012-05-28 Eli Zaretskii <eliz@gnu.org>
9212 * w32term.c (my_bring_window_to_top): New function.
9213 (x_raise_frame): Use handle returned by DeferWindowPos, which
9214 could be different from the original one.
9215 Call my_bring_window_to_top instead of my_set_foreground_window.
9218 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
9219 by calling BringWindowToTop.
9221 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
9222 (WM_EMACS_END): Increase by one.
9224 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
9226 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
9227 This avoids undefined behavior that might cause the eassert
9228 to not catch an out-of-range value.
9230 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
9232 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
9233 Update dependencies.
9235 2012-05-27 Eli Zaretskii <eliz@gnu.org>
9237 * bidi.c (bidi_mirror_char): Fix last change.
9239 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
9241 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
9242 when referring to sectname field in printf format.
9244 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
9246 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
9247 Only r_alloc_inhibit_buffer_relocation needed to be added;
9248 the others were already declared.
9250 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
9251 before checking whether it's out of range. Put the check inside
9253 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
9255 2012-05-27 Ken Brown <kbrown@cornell.edu>
9257 * callproc.c (Fcall_process): Restore a line that was accidentally
9258 commented out in the 2011-02-13 change (bug#11547).
9260 2012-05-27 Eli Zaretskii <eliz@gnu.org>
9262 * lisp.h [REL_ALLOC]: Add prototypes for external functions
9263 defined on ralloc.c.
9265 * buffer.c [REL_ALLOC]: Remove prototypes of
9266 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
9267 they are now on lisp.h.
9269 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
9271 * search.c (search_buffer): Use it to inhibit relocation of buffer
9272 text while re_search_2 is doing its job, because re_search_2 is
9273 passed C pointers to buffer text. (Bug#11519)
9275 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
9278 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
9279 state after an additional call to move_it_in_display_line_to, keep
9280 the values of it->max_ascent and it->max_descent found for the
9282 (pos_visible_p): Revert the comparison against bottom_y to what it
9283 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
9286 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
9288 Fix coding-related core dumps with gcc -ftrapv.
9289 The code was computing A - B, where A and B are pointers, and B is
9290 random garbage. This can lead to core dumps on platforms that
9291 have special pointer registers, and it also leads to core dumps on
9292 x86-64 when compiled with gcc -ftrapv. The fix is to compute
9293 A - B only when B is initialized properly.
9294 * coding.c (coding_set_source, coding_set_destination): Return void.
9295 (coding_change_source, coding_change_destinations): New functions,
9296 with the old behaviors of coding_set_source and coding_set_destination.
9297 All callers that need an offset changed to use these new functions.
9299 2012-05-26 Glenn Morris <rgm@gnu.org>
9301 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
9303 2012-05-26 Eli Zaretskii <eliz@gnu.org>
9305 Extend mouse support on W32 text-mode console.
9306 * xdisp.c (draw_row_with_mouse_face):
9307 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
9309 * w32console.c: Include window.h.
9310 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
9312 (initialize_w32_display): Initialize mouse-highlight data.
9314 * w32inevt.c: Include termchar.h and window.h.
9315 (do_mouse_event): Support mouse-autoselect-window. When the mouse
9316 moves, call note_mouse_highlight. If help_echo changed, call
9317 gen_help_event to produce help-echo message in the echo area.
9318 Call clear_mouse_face if mouse_face_hidden is set in the mouse
9321 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
9323 * lread.c (read1): Simplify slightly to avoid an overflow warning
9324 with GCC 4.7.0 on x86-64.
9326 2012-05-26 Eli Zaretskii <eliz@gnu.org>
9328 * bidi.c (bidi_mirror_char): Revert last change: an int is
9329 definitely wide enough here.
9331 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
9333 Fix integer width and related bugs (Bug#9874).
9334 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
9335 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
9336 (string_bytes, check_sblock, allocate_string_data):
9337 (compact_small_strings, Fmake_bool_vector, make_string)
9338 (make_unibyte_string, make_multibyte_string)
9339 (make_string_from_bytes, make_specified_string)
9340 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
9341 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
9343 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9344 (allocate_pseudovector):
9345 Use int, not EMACS_INT, where int is wide enough.
9346 (inhibit_garbage_collection, Fgarbage_collect):
9347 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9348 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
9349 int might not be wide enough.
9350 (bidi_cache_search, bidi_cache_find, bidi_init_it)
9351 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
9352 (bidi_at_paragraph_end, bidi_find_paragraph_start)
9353 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
9354 (bidi_level_of_next_char, bidi_move_to_visually_next):
9355 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9356 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
9357 (Fkill_buffer, Fset_buffer_major_mode)
9358 (advance_to_char_boundary, Fbuffer_swap_text)
9359 (Fset_buffer_multibyte, overlays_at, overlays_in)
9360 (overlay_touches_p, struct sortvec, record_overlay_string)
9361 (overlay_strings, recenter_overlay_lists)
9362 (adjust_overlays_for_insert, adjust_overlays_for_delete)
9363 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
9364 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
9365 (Foverlay_recenter, last_overlay_modification_hooks_used)
9366 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
9367 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9368 (validate_region): Omit unnecessary test for b <= e,
9369 since that's guaranteed by the previous test.
9370 (adjust_overlays_for_delete): Avoid pos + length overflow.
9371 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
9372 (report_overlay_modification):
9373 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9374 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
9375 Omit pointer cast, which isn't needed anyway, and doesn't work
9376 after the EMACS_INT -> ptrdiff_t change.
9377 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
9378 * buffer.h: Adjust decls to match defn changes elsewhere.
9379 (struct buffer_text, struct buffer):
9380 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9381 Use EMACS_INT, not int, where int might not be wide enough.
9382 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
9383 not int, to avoid needless 32-bit limit on 64-bit hosts.
9384 (exec_byte_code): Use tighter memory-full test, one that checks
9385 for alloca overflow. Don't compute the address of the object just
9386 before an array, as that's not portable. Use EMACS_INT, not
9387 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
9388 * callint.c (Fcall_interactively):
9389 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9390 * callproc.c (call_process_kill, Fcall_process):
9391 Don't assume pid_t fits into an Emacs fixnum.
9392 (call_process_cleanup, Fcall_process, child_setup):
9393 Don't assume pid_t fits into int.
9394 (call_process_cleanup, Fcall_process, delete_temp_file)
9395 (Fcall_process_region):
9396 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9397 (Fcall_process): Simplify handling of volatile integers.
9398 Use int, not EMACS_INT, where int will do.
9399 * casefiddle.c (casify_object, casify_region, operate_on_word)
9400 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
9401 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9402 (casify_object): Avoid integer overflow when overallocating buffer.
9403 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
9404 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
9405 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
9406 * category.h (CATEGORYP): Don't assume arg is nonnegative.
9407 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
9408 integers are now checked earlier. All uses replaced with XINT.
9410 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9411 For CCL_MapSingle, check that content and value are in int range.
9412 (ccl_driver, Fregister_code_conversion_map):
9413 Check that Vcode_version_map_vector is a vector.
9414 (resolve_symbol_ccl_program): Check that vector header is in range.
9415 Always copy the vector, so that we can check its contents reliably
9416 now rather than having to recheck each instruction as it's being
9417 executed. Check that vector words fit in 'int'.
9418 (ccl_get_compiled_code, Fregister_ccl_program)
9419 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
9420 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
9421 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
9422 contents are in range.
9423 (Fccl_execute_on_string): Check that status is in range.
9424 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
9425 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
9426 Accept and return EMACS_INT, not int, because callers can pass values
9428 (c_string_width, strwidth, lisp_string_width, chars_in_text)
9429 (multibyte_chars_in_text, parse_str_as_multibyte)
9430 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
9431 (str_as_unibyte, str_to_unibyte, string_count_byte8)
9432 (string_escape_byte8, Fget_byte):
9433 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9434 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
9435 avoid mishandling large integers.
9436 * character.h: Adjust decls to match defn changes elsewhere.
9437 * charset.c (load_charset_map_from_file, find_charsets_in_text)
9438 (Ffind_charset_region):
9439 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9440 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
9441 (load_charset_map_from_vector, Fdefine_charset_internal):
9442 Don't assume fixnum fits in int.
9443 (load_charset_map_from_vector, Fmap_charset_chars):
9444 Remove now-unnecessary CHECK_NATNUMs.
9445 (Fdefine_charset_internal): Check ranges here, more carefully.
9446 Don't rely on undefined behavior with signed left shift overflow.
9447 Don't assume unsigned int fits into fixnum, or that fixnum fits
9448 into unsigned int. Don't require max_code to be a valid fixnum;
9449 that's not true for gb10830 4-byte on a 32-bit host. Allow
9450 invalid_code to be a cons, for the same reason. Require code_offset
9451 to be a character. Avoid int overflow if max_char is close
9453 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
9454 this is intended anyway and avoids some undefined behavior.
9455 (load_charset_map): Pass unsigned, not int, as 2nd arg of
9456 INDEX_TO_CODE_POINT, as that's what it expects.
9457 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
9458 * charset.h (DECODE_CHAR): Return int, not unsigned;
9459 this is what was intended anyway, and it avoids undefined behavior.
9460 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
9461 integer-overflow issues.
9462 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
9463 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
9464 where the argument is EMACS_INT, and this behavior is not intended.
9465 * chartab.c (Fmake_char_table, Fset_char_table_range)
9466 (uniprop_get_decoder, uniprop_get_encoder):
9467 Don't assume fixnum fits in int.
9468 * cmds.c (move_point): New function, that does the gist of
9469 Fforward_char and Fbackward_char, but does so while checking
9470 for integer overflow more accurately.
9471 (Fforward_char, Fbackward_char): Use it.
9472 (Fforward_line, Fend_of_line, internal_self_insert)
9473 (internal_self_insert):
9474 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9475 Fix a FIXME, by checking for integer overflow when calculating
9476 target_clm and actual_clm.
9477 * coding.c (detect_coding_XXX, encode_coding_XXX, CODING_DECODE_CHAR)
9478 (CODING_ENCODE_CHAR, CODING_CHAR_CHARSET, CODING_CHAR_CHARSET_P)
9479 (ASSURE_DESTINATION, coding_alloc_by_realloc)

10195 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
10196 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
10197 * textprop.c, tparam.c (NULL): Remove.
10198 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
10199 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
10200 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
10201 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
10202 * xterm.c (input_signal_count): Assume volatile works.
10204 2012-05-21 Ken Brown <kbrown@cornell.edu>
10206 * xgselect.c (xg_select): Fix first argument in call to 'select'
10209 2012-05-20 Ken Brown <kbrown@cornell.edu>
10211 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
10212 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
10214 2012-05-19 Ken Brown <kbrown@cornell.edu>
10216 * xfns.c (x_in_use): Remove `static' qualifier.
10217 * xterm.h (x_in_use): Declare.
10218 * xgselect.c: Include xterm.h.
10219 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
10220 and `display_arg' (bug#9754).
10222 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
10224 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
10226 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
10227 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
10229 2012-05-18 Eli Zaretskii <eliz@gnu.org>
10231 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
10233 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
10234 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
10236 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
10237 reference to image_cache->refcount.
10238 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
10240 2012-05-17 Juri Linkov <juri@jurta.org>
10242 * search.c (Fword_search_regexp, Fword_search_backward)
10243 (Fword_search_forward, Fword_search_backward_lax)
10244 (Fword_search_forward_lax): Move functions to isearch.el
10245 (bug#10145, bug#11381).
10247 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
10249 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
10251 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
10253 * lread.c (init_obarray): Declare Qt and Qnil as special.
10255 2012-05-14 Glenn Morris <rgm@gnu.org>
10257 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
10258 Put "libexec" before "bin", for the sake of init_callproc_1.
10260 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
10262 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
10264 * unexaix.c: Port to more-recent AIX compilers.
10265 (report_error, report_error_1, make_hdr, copy_sym)
10266 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
10267 Make arguments const char *, not char *, to avoid violations of C
10268 standard and to fix some AIX warnings reported by Gilles Pion.
10270 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10272 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
10273 already have overlays loaded.
10274 (handle_single_display_spec): Before returning without displaying
10275 fringe bitmap, synchronize the bidi iterator with the main display
10276 iterator, by calling iterate_out_of_display_property.
10277 (iterate_out_of_display_property): Detect buffer iteration by
10278 testing that it->string is a Lisp string.
10279 (get_next_display_element): When the current object is exhausted,
10280 and there's something on it->stack, call set_iterator_to_next to
10281 proceed with what's on the stack, instead of returning zero.
10282 (set_iterator_to_next): If called at the end of a Lisp string,
10283 proceed to consider_string_end without incrementing string
10284 position. Don't increment display vector index past the end of
10285 the display vector. (Bug#11417)
10286 (pos_visible_p): Don't report a position visible when move_it_to
10287 stopped at the last line of window, which happens to be scanned
10288 backwards by the bidi iteration. (Bug#11464)
10290 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10292 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
10293 and right-margin display specs even if the spec is invalid or we
10294 are on a TTY, and thus unable to display on the fringes.
10295 That's because the text with the property will not be displayed anyway,
10296 so we need to signal to the caller that this is a "replacing"
10297 display spec. This fixes display when the spec is invalid or we
10300 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
10302 * unexaix.c (make_hdr): Fix typo in prototype.
10303 This bug broke the build on AIX. Problem reported by Gilles Pion.
10305 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
10307 * keyboard.c (kbd_buffer_get_event): Read special events also in
10308 batch mode. (Bug#11415)
10310 2012-05-12 Glenn Morris <rgm@gnu.org>
10312 * ns.mk: Update for ns_appbindir no longer having trailing "/".
10314 2012-05-12 Eli Zaretskii <eliz@gnu.org>
10316 * lisp.mk (lisp): Add newcomment.elc.
10318 2012-05-12 Glenn Morris <rgm@gnu.org>
10320 * Makefile.in (MKDIR_P): New, set by configure.
10321 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
10323 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
10325 Remove unused function hourglass_started.
10326 * dispextern.h (hourglass_started):
10327 * w32fns.c (hourglass_started):
10328 * xdisp.c (hourglass_started): Remove.
10330 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
10332 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
10333 Update dependencies.
10335 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
10337 * xgselect.c (xg_select): Put maxfds+1 into a var.
10338 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
10340 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
10342 2012-05-10 Dave Abrahams <dave@boostpro.com>
10344 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
10345 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
10347 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
10349 * dbusbind.c (xd_registered_buses): New internal Lisp object.
10350 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
10351 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
10352 Initialize xd_registered_buses.
10354 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
10356 Untag more efficiently if USE_LSB_TAG.
10357 This is based on a proposal by YAMAMOTO Mitsuharu in
10358 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
10359 For an admittedly artificial (nth 8000 longlist) benchmark on
10360 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
10361 Emacs's overall text size by 1%.
10362 * lisp.h (XUNTAG): New macro.
10363 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
10364 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
10365 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
10366 * eval.c (Fautoload):
10367 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
10368 * frame.h (XFRAME): Use XUNTAG.
10370 Port recent dbusbind.c changes to 32-bit --with-wide-int.
10371 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
10372 Remove unportable assumptions about print widths of types like
10374 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
10375 intptr_t when converting between pointer and integer, to avoid GCC
10376 warnings about wrong width.
10378 2012-05-09 Eli Zaretskii <eliz@gnu.org>
10380 * w32proc.c (new_child): Force Windows to reserve only 64KB of
10381 stack for each reader_thread, instead of defaulting to 8MB
10382 determined by the linker. This avoids failures in creating
10383 subprocesses on Windows 7, see the discussion in this thread:
10384 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
10386 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
10388 Fix up display of the *Minibuf-0* buffer in the mini window.
10389 * keyboard.c (read_char): Don't clear the echo area if there's no
10391 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
10392 contents of *Minibuf-0*) if there's no message displayed in its stead.
10394 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
10396 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
10399 2012-05-06 Chong Yidong <cyd@gnu.org>
10401 * lisp.mk (lisp): Update.
10403 2012-05-05 Jim Meyering <meyering@redhat.com>
10405 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
10407 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
10409 * data.c (PUT_ERROR): New macro.
10410 (syms_of_data): Use it. Add new error type `user-error'.
10411 * undo.c (user_error): New function.
10412 (Fprimitive_undo): Use it.
10413 * print.c (print_error_message): Adjust print style for `user-error'.
10414 * keyboard.c (user_error): New function.
10415 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
10417 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
10419 Do not limit current-time-string to years 1000..9999.
10420 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
10421 (Fcurrent_time_string): Support any year that is supported by the
10422 underlying localtime representation. Don't use asctime, as it
10423 has undefined behavior for years outside the range -999..9999.
10425 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
10427 Fix race conditions involving setenv, gmtime, localtime, asctime.
10428 Without this fix, interrupts could mess up code that uses these
10429 nonreentrant functions, since setting TZ invalidates existing
10430 tm_zone or tzname values, and since most of these functions return
10431 pointers to static storage.
10432 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
10433 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
10434 Grow the critical sections to include not just invoking
10435 localtime/gmtime, but also accessing these functions' results
10436 including their tm_zone values if any, and any related TZ setting.
10437 (format_time_string): Last arg is now struct tm *, not struct tm **,
10438 so that the struct tm is saved in the critical section.
10439 All callers changed. Simplify allocation of initial buffer, partly
10440 motivated by the fact that memory allocation needs to be outside
10441 the critical section.
10443 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
10445 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
10446 with RESET_INTERVAL.
10448 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
10449 Remove duplicated buffer name initialization.
10451 2012-05-02 Jim Meyering <jim@meyering.net>
10453 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
10455 * xfns.c (x_window): Use xstrdup (Bug#11375).
10457 2012-05-02 Eli Zaretskii <eliz@gnu.org>
10459 * xdisp.c (pos_visible_p): If already at a newline from the
10460 display string before the 'while' loop, don't walk back the glyphs
10461 from it3.glyph_row. Solves assertion violation when the display
10462 string begins with a newline (egg.el). (Bug#11367)
10464 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
10466 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
10469 2012-05-01 Glenn Morris <rgm@gnu.org>
10471 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
10472 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
10473 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
10474 All were removed before 23.1.
10476 * dispnew.c: Remove HAVE_LIBNCURSES test;
10477 it is always true on relevant platforms.
10479 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
10480 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
10482 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
10484 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
10486 * .gdbinit (xpr): Remove checks for no longer existing misc types.
10487 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
10490 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
10492 Do not avoid creating empty evaporating overlays (Bug#9642).
10493 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
10494 That is, do not delete an evaporating overlay if it becomes
10495 empty after its bounds are adjusted to fit within its buffer.
10496 This fix caused other problems, and I'm reverting it until we get
10497 to the bottom of them.
10499 2012-04-27 Chong Yidong <cyd@gnu.org>
10501 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
10503 2012-04-27 Eli Zaretskii <eliz@gnu.org>
10505 * xdisp.c (pos_visible_p): If the window start position is beyond
10506 ZV, start the display from buffer beginning. Prevents assertion
10507 violation in init_iterator when the minibuffer window is scrolled
10508 via the scroll bar.
10510 * window.c (window_scroll_pixel_based): Likewise.
10512 2012-04-27 Chong Yidong <cyd@gnu.org>
10514 * keymap.c (where_is_internal): Doc fix (Bug#10872).
10516 2012-04-27 Glenn Morris <rgm@gnu.org>
10518 * fileio.c (Fcopy_file, Fset_file_selinux_context):
10519 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
10521 2012-04-27 Eli Zaretskii <eliz@gnu.org>
10523 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
10524 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
10526 2012-04-26 Eli Zaretskii <eliz@gnu.org>
10528 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
10529 display element, check also the underlying string or buffer
10530 character. (Bug#11341)
10532 * w32menu.c: Include w32heap.h.
10533 (add_menu_item): If the call to AppendMenuW (via
10534 unicode_append_menu) fails, disable Unicode menus only if we are
10535 running on Windows 9X/Me.
10537 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
10539 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
10540 (xgetint): Add missing shift for LSB tags.
10542 2012-04-24 Martin Rudalics <rudalics@gmx.at>
10544 * keyboard.c (read_char): Don't wipe echo area for select window
10545 events: These might get delayed via `mouse-autoselect-window'
10548 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
10550 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
10551 manipulation of :loaded-from data.
10553 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
10555 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
10556 now a cons (bug#11311).
10558 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
10560 Do not create empty overlays with the evaporate property (Bug#9642).
10561 * buffer.c (Fmove_overlay): Delete an evaporating overlay
10562 if it becomes empty after its bounds are adjusted to fit within
10563 its buffer. Without this fix, in a nonempty buffer (let ((o
10564 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
10565 yields an empty overlay that has the evaporate property, which is
10566 not supposed to happen.
10568 Fix minor GTK3 problems found by static checking.
10569 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
10570 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
10571 (struct _EmacsFixedClass, emacs_fixed_get_type):
10572 Move decls here from emacsgtkfixed.h, since they needn't be public.
10573 (emacs_fixed_get_type): Now static.
10574 (emacs_fixed_class_init): Omit unused local.
10575 (emacs_fixed_child_type): Remove; unused.
10576 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
10577 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
10578 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
10579 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
10580 (EMACS_FIXED_GET_CLASS): Remove; unused.
10581 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
10583 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
10584 Problem reported by Juanma Barranquero for Windows -Wunused-function.
10586 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
10588 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
10589 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
10590 (__malloc_size_t, __malloc_ptrdiff_t):
10591 Remove. All uses removed, replaced by the definiens if needed,
10592 since we can assume C89 or better now.
10593 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

10601 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
10602 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
10603 Define using prototypes, not old style.
10604 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
10605 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
10606 (align): Don't assume that signed integer overflow wraps around.
10607 Omit unused local var.
10608 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
10609 (_free_internal_nolock, memalign, mallochook, reallochook):
10610 Omit no-longer-needed casts.
10611 (valloc): Use getpagesize, not __getpagesize.
10612 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
10613 (struct hdr): The 'magic' member is now size_t, not unsigned long.
10615 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
10617 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
10619 Move functions from C to Lisp. Make non-blocking method calls
10620 the default. Implement further D-Bus standard interfaces.
10622 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.

10681 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
10683 * sysdep.c [__FreeBSD__]: Minor cleanups.
10684 (list_system_processes, system_process_attributes) [__FreeBSD__]:
10685 Use Emacs indenting style more consistently. Avoid some casts.

10704 * print.c (print_preprocess): Only check print_depth if print-circle
10706 (print_object): Check for cycles even when print-circle is nil and

10711 * process.c (wait_reading_process_output): If EIO occurs on a pty,
10712 set the status to "failed" and ensure that sentinel is run.
10714 2012-04-20 Glenn Morris <rgm@gnu.org>
10716 * process.c (Fset_process_inherit_coding_system_flag)
10717 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

10770 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
10771 (NEED_MEM_INSERT): New macro.
10772 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
10773 Remove one incorrect comment and fix another.

10809 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
10810 * s/netbsd.h, s/sol2-6.h:
10811 Remove definition of GC_MARK_STACK, since the default now works.
10812 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:

10840 2012-04-11 Daniel Colascione <dancol@dancol.org>
10842 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
10843 against is gone. It's better to use vfork now so that when Cygwin
10844 gains a new, working vfork, we use it automatically (bug#10398).
10846 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

10899 * minibuf.c (Fread_variable): Callers changed.
10901 2012-04-09 Eli Zaretskii <eliz@gnu.org>
10903 * xdisp.c (set_cursor_from_row): If the display string appears in
10904 the buffer at position that is closer to point than the position
10905 after the display string, display the cursor on the first glyph of
10906 the display string. Fixes cursor display when a 'display' text
10907 property immediately follows invisible text. (Bug#11094)
10909 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
10911 composite.c: use 'double' consistently
10912 * composite.c (get_composition_id): Use 'double' consistently
10913 instead of converting 'float' to 'double' and vice versa; this is
10914 easier to understand and avoids a GCC warning.
10916 2012-04-09 Glenn Morris <rgm@gnu.org>

10963 [!WINDOWSNT]: New macros.
10964 (init_libxml2_functions, libxml2_loaded_p): New functions.

10968 Calls xmlCleanupParser only if libxml2 was loaded (or statically
10970 (Flibxml_parse_html_region, Flibxml_parse_xml_region):

10982 * indent.c (Fvertical_motion): If there is a display string at
10983 point, use it.vpos to compute how many lines to backtrack after
10984 move_it_to point. (Bug#11133)
10986 2012-04-06 Eli Zaretskii <eliz@gnu.org>
10988 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
10989 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
10990 about subtle differences between FETCH_CHAR* and STRING_CHAR*
10991 macros related to unification of CJK characters. For the details,
10992 see the discussion following the message here:

11009 2012-03-31 Eli Zaretskii <eliz@gnu.org>
11011 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
11012 position we get to after a call to move_it_to fails the
11013 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
11014 only if we wind up in a string from display property. (Bug#11063)
11016 * window.c (Fdelete_other_windows_internal): Invalidate the row
11017 and column information about mouse highlight, so that redisplay
11018 restores it after reallocating the glyph matrices. (Bug#7464)
11020 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
11021 string comes from a `display' text property, use the buffer
11022 position of that property as if we actually saw that position in
11024 (move_it_by_lines): Remove the assertion that
11025 "it->current_x == 0 && it->hpos == 0" which can be legitimately
11026 violated when there's a before-string at the beginning of a line.

11035 (display_line): Call extend_face_to_end_of_line when the default
11036 face was remapped. (Bug#11068)

11084 2012-03-23 Eli Zaretskii <eliz@gnu.org>
11086 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
11087 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
11088 when fetching a multibyte character consumes more bytes than
11089 CHAR_BYTES returns, due to unification of CJK characters in
11090 string_char. (Bug#11073)
11092 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
11094 * process.c (wait_reading_process_output): Handle pty disconnect
11095 by refraining from sending oneself a SIGCHLD (bug#10933).

11101 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
11102 Mark string as coming from a prefix property.
11103 (handle_face_prop): Use default face for prefix strings (Bug#4281).
11104 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
11106 2012-03-21 Chong Yidong <cyd@gnu.org>
11108 * xfaces.c (Vface_remapping_alist): Doc fix.
11110 2012-03-20 Eli Zaretskii <eliz@gnu.org>
11112 * w32proc.c (Fw32_set_console_codepage)
11113 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):

11118 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
11119 to reflect default non-nil value of redisplay-dont-pause.
11121 2012-03-19 Kenichi Handa <handa@m17n.org>
11123 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
11124 it fit in a valid range (Bug#11003).
11126 2012-03-18 Eli Zaretskii <eliz@gnu.org>
11128 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
11129 that is not from display property, accept the row as a "cursor
11130 row" if one of the string's character has a non-nil `cursor'
11131 property. Fixes cursor positioning when there are newlines in
11132 overlay strings, e.g. in icomplete.el. (Bug#11035)
11134 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
11136 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
11138 2012-03-12 Chong Yidong <cyd@gnu.org>
11140 * eval.c (inhibit_lisp_code): Rename from
11141 inhibit_window_configuration_change_hook; move from window.c.
11143 * xfns.c (unwind_create_frame_1, Fx_create_frame):
11144 * window.c (run_window_configuration_change_hook)
11145 (syms_of_window): Callers changed.

11151 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
11153 2012-03-10 Chong Yidong <cyd@gnu.org>
11155 * frame.c (other_visible_frames): Don't assume the selected frame
11156 is visible (Bug#10955).

11164 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
11165 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
11168 2012-03-03 Glenn Morris <rgm@gnu.org>
11170 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
11172 2012-03-02 Eli Zaretskii <eliz@gnu.org>
11174 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
11175 position past the first glyph_row that ends at ZV. (Bug#10902)
11176 (redisplay_window, next_element_from_string): Fix typos in
11178 (redisplay_window): Pass to move_it_vertically the margin in
11179 pixels, not in screen lines.
11181 2012-03-02 Glenn Morris <rgm@gnu.org>
11183 * buffer.c (buffer-list-update-hook): Doc fix.
11185 2012-02-29 Eli Zaretskii <eliz@gnu.org>
11187 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
11188 push_it before setting up the iterator for the first overlay
11189 string, even if we have an empty string loaded.
11190 (next_overlay_string): If there's an empty string on the iterator
11191 stack, pop the stack. (Bug#10903)
11193 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
11195 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
11196 Suggested by Stefan Monnier in
11197 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
11198 * alloc.c (widen_to_Lisp_Object): New static function.
11199 (mark_memory): Also mark Lisp_Objects by fetching pointer words
11200 and widening them to Lisp_Objects. This would work even if
11201 USE_LSB_TAG is defined and wide integers are used, which might
11202 happen in a future version of Emacs.
11204 2012-02-25 Chong Yidong <cyd@gnu.org>
11206 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
11209 * xselect.c (Fx_selection_exists_p): Doc fix.
11210 (x_clipboard_manager_save_all): Print an informative message
11211 before saving to clipboard manager.
11213 2012-02-24 Chong Yidong <cyd@gnu.org>
11215 * keyboard.c (process_special_events): Handle all X selection
11216 requests in kbd_buffer, not just the next one (Bug#8869).
11218 2012-02-23 Chong Yidong <cyd@gnu.org>
11220 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
11221 call when setting menu-bar-lines and tool-bar-lines parameters.
11222 (unwind_create_frame_1): New helper function.
11224 * window.c (inhibit_window_configuration_change_hook): New var.
11225 (run_window_configuration_change_hook): Obey it.
11226 (syms_of_window): Initialize it.
11228 2012-02-22 Chong Yidong <cyd@gnu.org>
11230 * xterm.c (x_draw_image_relief): Add missing type check for
11231 Vtool_bar_button_margin (Bug#10743).
11233 2012-02-21 Chong Yidong <cyd@gnu.org>
11235 * fileio.c (Vfile_name_handler_alist): Doc fix.
11237 * buffer.c (Fget_file_buffer): Protect against invalid file
11238 handler return value.
11240 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
11242 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
11243 when computing $valmask.
11245 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
11246 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
11247 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
11248 It's useless in that case, and it can cause problems on hosts
11249 that allocate halves of EMACS_INT values separately.
11250 Reported by Dan Horák. Diagnosed by Andreas Schwab in
11251 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
11252 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
11253 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
11254 it avoids undefined behavior on hosts where shifting right by more
11255 than the word width has undefined behavior.
11257 2012-02-19 Chong Yidong <cyd@gnu.org>
11259 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
11260 (Funhandled_file_name_directory, Ffile_name_as_directory)
11261 (Fdirectory_file_name, Fexpand_file_name)
11262 (Fsubstitute_in_file_name): Protect against invalid file handler
11263 return values (Bug#10845).
11265 2012-02-18 Eli Zaretskii <eliz@gnu.org>
11267 * .gdbinit (pitx): Fix incorrect references to fields of the

11277 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
11279 2012-02-15 Chong Yidong <cyd@gnu.org>
11281 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
11282 marked as special. Also, starting docstrings with * is obsolete.

11295 * keymap.c (Fsingle_key_description): Handle char ranges.
11297 2012-02-12 Chong Yidong <cyd@gnu.org>
11299 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
11300 as that creates a dangerous corner case.
11302 * window.c (Fdelete_window_internal): Invalidate the mouse
11303 highlight (Bug#9904).
11305 2012-02-12 Glenn Morris <rgm@gnu.org>

11310 * nsselect.m (Fx_own_selection_internal)
11311 (Fx_disown_selection_internal, Fx_selection_exists_p)
11312 (Fx_selection_owner_p, Fx_get_selection_internal):
11313 Sync docs and argument specs with the xselect.c versions.
11315 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>

11335 2012-02-07 Chong Yidong <cyd@gnu.org>
11337 * buffer.c (Fbuffer_local_variables)
11338 (buffer_lisp_local_variables): Handle unbound vars correctly;
11339 don't let Qunbound leak into Lisp.
11341 2012-02-07 Glenn Morris <rgm@gnu.org>
11343 * image.c (Fimagemagick_types): Doc fix.
11345 * image.c (imagemagick-render-type): Change it from a lisp object
11346 to an integer. Move the doc here from the lisp manual.
11347 Treat all values not equal to 0 the same.

11359 2012-02-04 Chong Yidong <cyd@gnu.org>
11361 * nsterm.m: Declare a global (Bug#10694).
11363 2012-02-04 Eli Zaretskii <eliz@gnu.org>
11365 * w32.c (get_emacs_configuration_options):
11366 Include --enable-checking, if specified, in the return value.
11368 2012-02-04 Martin Rudalics <rudalics@gmx.at>
11370 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols

11376 before BEGV. (Bug#10696)
11378 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
11380 Handle overflow when computing char display width (Bug#9496).
11381 * character.c (char_width): Return EMACS_INT, not int.
11382 (char_width, c_string_width): Check for overflow when
11383 computing the width; this is possible now that individual
11384 characters can have unbounded width. Problem introduced
11385 by merge from Emacs 23 on 2012-01-19.
11387 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

11402 2012-02-02 Kenichi Handa <handa@m17n.org>
11404 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
11405 0, do not call append_composite_glyph.
11407 2012-02-02 Kenichi Handa <handa@m17n.org>
11409 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
11411 (x_produce_glyphs): If the component of a composition is a null
11412 string, set it->pixel_width to 1 to avoid zero-width glyph.
11414 2012-02-01 Eli Zaretskii <eliz@gnu.org>
11416 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
11417 first 2 arguments are identical. This makes inserting large
11418 output from a subprocess an order of magnitude faster on
11419 MS-Windows, where all sbrk'ed memory is always contiguous.
11421 2012-01-31 Glenn Morris <rgm@gnu.org>
11423 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

11459 2012-01-21 Chong Yidong <cyd@gnu.org>
11461 * floatfns.c (Fcopysign): Make the second argument non-optional,
11462 since nil is not allowed anyway.
11464 2012-01-21 Andreas Schwab <schwab@linux-m68k.org>

11477 * character.c (char_width): New function.
11478 (Fchar_width, c_string_width, lisp_string_width):

11504 2012-01-11 Glenn Morris <rgm@gnu.org>
11506 * lread.c (init_lread): If no-site-lisp, remove site-lisp dirs
11507 from load-path also when installation-directory is nil. (Bug#10208)
11509 2012-01-10 Glenn Morris <rgm@gnu.org>
11511 * emacs.c (syms_of_emacs) <installation-directory>: Doc fix.
11513 * epaths.in (PATH_LOADSEARCH, PATH_EXEC, PATH_DATA, PATH_DOC):
11514 Update template values to be closer to their typical values these days.
11516 2012-01-09 Eli Zaretskii <eliz@gnu.org>
11518 * xdisp.c (rows_from_pos_range): Accept additional argument
11519 DISP_STRING, and accept any glyph in a row whose object is that
11520 string as eligible for mouse highlight. Fixes mouse highlight of
11521 display strings from overlays. (Bug#10464)
11523 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
11525 emacs: fix an auto-save permissions race condition (Bug#10400)
11526 * fileio.c (auto_saving_dir_umask): New static var.
11527 (Fmake_directory_internal): Use it.
11528 (do_auto_save_make_dir): Set it, instead of invoking chmod after
11529 creating the directory. The old code temporarily assigns
11530 too-generous permissions to the directory.
11531 (do_auto_save_eh): Clear it.
11532 (Fdo_auto_save): Catch all errors, not just file errors, so
11533 that the var is always cleared.
11535 2012-01-07 Eli Zaretskii <eliz@gnu.org>
11537 * search.c (scan_buffer): Pass character positions to
11538 know_region_cache, not byte positions. (Bug#6540)

12042 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
12043 to 4 (xorl, subq, cmpq, setbe).
12044 * alloc.c (pure): Always extern now, since that's the
12045 VIRT_ADDR_VARIES behavior.
12046 (PURE_POINTER_P): Use a single comparison, not two, for
12047 consistency with the new puresize.h.
12048 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
12049 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

12132 2011-11-14 Eli Zaretskii <eliz@gnu.org>
12134 * xdisp.c (display_line): Move the call to
12135 highlight_trailing_whitespace before the call to
12136 compute_line_metrics, since the latter needs to see the final
12137 faces of all the glyphs to compute ROW's hash value.
12138 Fixes assertion violations in row_equal_p. (Bug#10035)
12140 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
12142 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

12202 The trivial performance wins aren't worth the portability hassles; see
12203 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
12205 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

12279 (window_box_width, window_box_left, window_box_left_offset)
12280 (window_box_right, window_box_right_offset): Declare extern.
12281 Otherwise, these inline functions do not conform to C99 and
12282 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
12283 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
12284 * intervals.c (adjust_intervals_for_insertion)

12287 (static_offset_intervals): Remove.
12288 (offset_intervals): Rewrite using the old contents of
12289 static_offset_intervals. The old version didn't conform to C99
12290 because an extern inline function contained a reference to an
12291 identifier with static linkage.

12494 possible random value that matches one of those tested as
12495 condition to clear the mouse face.
12497 2011-10-28 Chong Yidong <cyd@gnu.org>
12499 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
12501 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
12503 * window.c (make_window): Initialize phys_cursor_on_p.
12505 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
12507 * lisp.h (struct Lisp_Symbol): Update comments.
12509 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
12511 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
12513 2011-10-28 Eli Zaretskii <eliz@gnu.org>
12515 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
12516 <oslsachem@gmail.com> for helping to debug this.
12518 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
12519 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
12520 (g_b_init_get_glyph_outline_w): New static variables.
12521 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
12522 (GetGlyphOutlineW_Proc): New typedefs.
12523 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
12524 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
12526 (w32font_open_internal, compute_metrics):
12527 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
12528 instead of calling the "wide" APIs directly.
12530 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
12532 * w32.h (syms_of_w32font): Add prototype.
12534 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
12536 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
12537 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
12538 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
12539 (Fmove_to_window_line): Doc fix.
12541 2011-10-27 Chong Yidong <cyd@gnu.org>
12543 * process.c (make_process): Set gnutls_state to NULL.
12545 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
12546 non-NULL, regardless of GNUTLS_INITSTAGE.
12547 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
12548 an error. Set process slots as soon as we allocate them.
12550 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
12552 2011-10-27 Chong Yidong <cyd@gnu.org>
12554 * gnutls.c (emacs_gnutls_deinit): New function.
12555 Deallocate credentials structures as well as calling gnutls_deinit.
12556 (Fgnutls_deinit, Fgnutls_boot): Use it.
12558 * process.c (make_process): Initialize GnuTLS credentials to NULL.
12559 (deactivate_process): Call emacs_gnutls_deinit.
12561 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
12563 * image.c (x_create_x_image_and_pixmap):
12564 * w32.c (sys_rename, w32_delayed_load):
12565 * w32font.c (fill_in_logfont):
12566 * w32reg.c (x_get_string_resource): Silence compiler warnings.
12568 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
12570 * w32fns.c (w32_default_color_map): New function,
12571 extracted from Fw32_default_color_map.
12572 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
12574 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
12576 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
12578 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
12580 * keyboard.c (test_undefined): New function (bug#9751).
12581 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
12583 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
12585 * sysdep.c (init_sys_modes): Fix the check for the controlling
12586 terminal (Bug#6649).
12588 2011-10-20 Eli Zaretskii <eliz@gnu.org>
12590 * dispextern.h (struct bidi_it): New member next_en_type.
12592 * bidi.c (bidi_line_init): Initialize the next_en_type member.
12593 (bidi_resolve_explicit_1): When next_en_pos is valid for the
12594 current character, check also for next_en_type being WEAK_EN.
12595 (bidi_resolve_weak): Don't enter the expensive loop if the current
12596 position is before next_en_pos. Record the bidi type of the first
12597 non-ET, non-BN character we find, in addition to its position.
12598 (bidi_level_of_next_char): Invalidate next_en_type when
12599 next_en_pos is over-stepped.
12601 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
12603 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
12604 * editfns.c: Rewrite current-time-zone so that it invokes
12605 the equivalent of (format-time-string "%Z") to get the time zone name.
12606 This fixes a bug when the time zone name contains characters that
12607 need converting from the system time locale to Emacs internal format.
12608 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
12609 that patch fixed format-time-string to do the conversion, but
12610 I forgot to fix current-time-zone.
12611 (format_time_string): New function, containing most of
12612 what Fformat_time_string used to contain.
12613 (Fformat_time_string): Rewrite in terms of format_time_string.
12614 This doesn't change this function's behavior.
12615 (current-time-zone): Rewrite to use format_time_string.
12616 This fixes the bug reported by Michael Schierl in
12617 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
12618 Jason Rumney's 2007-06-07 change worked around this bug, but
12620 * systime.h (tzname, timezone): Remove no-longer-used declarations.
12622 2011-10-19 Eli Zaretskii <eliz@gnu.org>
12624 * xdisp.c (start_display): If the character at POS is displayed
12625 via a display vector, reset IT->current.dpvec_index to zero.
12626 (try_window_reusing_current_matrix): If a line ends in a display
12627 vector or the next line starts in a display vector, continue
12628 redrawing the window even though the character position of
12629 start_row was reached.
12632 2011-10-18 Chong Yidong <cyd@gnu.org>
12634 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
12635 with nobreak-char-display too.
12637 2011-10-18 Eli Zaretskii <eliz@gnu.org>
12639 Fix part 3 of bug#9771.
12640 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
12641 (bidi_resolve_neutral): Don't enter the expensive loop looking for
12642 non-neutral characters if the current character is a paragraph
12643 separator (a.k.a. Newline). This avoids running the same
12644 expensive loop twice, once when we consume the preceding newline
12645 and the other time when the line actually needs to be displayed.
12646 Avoid the loop when we see neutrals on the base embedding level
12647 following a character whose directionality is the same as the
12648 paragraph's. This avoids running the expensive loop when a line
12649 ends in a long sequence of neutrals, like control characters.
12650 Add assertion against STRONG_AL type. Slightly rearrange code
12651 that determines the type of a neutral given the first non-neutral
12653 (bidi_level_of_next_char): Set next_en_pos to zero when
12654 invalidating its info.
12656 2011-10-17 Eli Zaretskii <eliz@gnu.org>
12658 * xdisp.c (push_display_prop): Determine whether to record string
12659 or buffer position by IT->string, not by IT->method. Allow
12660 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
12661 (move_it_vertically_backward): Don't look for character position
12662 immediately after the newline when in a continuation line.
12665 2011-10-15 Martin Rudalics <rudalics@gmx.at>
12667 * window.c (coordinates_in_window): Rewrite and delabelize
12668 vertical border check. (Bug#5357) (Bug#9618)
12670 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
12672 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
12673 errors in XSetWindowBorder (bug#9310).
12675 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
12677 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
12678 avoid crash when xmalloc overrun checking is enabled.
12680 2011-10-13 Eli Zaretskii <eliz@gnu.org>
12682 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
12683 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
12684 cursor motion with <left> and <right> arrow keys.
12686 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
12687 some callers set that themselves.
12689 2011-10-12 Eli Zaretskii <eliz@gnu.org>
12691 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
12692 display string and the previous row comes from the same string and
12693 is empty. (Bug#9739) (Bug#9738)
12695 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
12697 * doc.c (get_doc_string): Encode file name (bug#9735).
12699 2011-10-12 Eli Zaretskii <eliz@gnu.org>
12701 * bidi.c (bidi_level_of_next_char):
12702 * xdisp.c (get_visually_first_element): Remove old incorrect
12703 comments regarding the Unicode Line Separator character.
12705 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
12707 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
12709 * alloc.c (Fgc_status): Do not access beyond zombies array
12710 boundary if nzombies > MAX_ZOMBIES.
12711 * alloc.c (dump_zombies): Add missing format specifier.
12713 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
12715 * xdisp.c (set_cursor_from_row): Simplify conditionals,
12716 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
12718 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
12719 Some packages use them to denote characters with modifiers.
12721 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
12723 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
12724 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
12725 matching a pp-number. Rename parameter var to var1.
12727 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
12729 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
12731 2011-10-08 Glenn Morris <rgm@gnu.org>
12733 * callint.c (Fcall_interactively): Give a more explicit error for the
12734 'c' case with a non-character input. (Bug#8479)
12736 2011-10-08 Eli Zaretskii <eliz@gnu.org>
12738 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
12740 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
12741 lines that are hscrolled on the left.
12743 * dispnew.c (buffer_posn_from_coords): Account for a possible
12744 presence of header-line. (Bug#4426)
12746 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
12748 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
12749 Don't advertise functionality which we discourage or doesn't work.
12751 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
12753 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
12754 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
12755 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
12756 this makes Emacs dump core during garbage collection on rare
12757 occasions. sizeof is obviously inferior to offsetof here, so
12758 stick with offsetof.
12759 (GC_POINTER_ALIGNMENT): New macro.
12760 (mark_memory): Omit 3rd (offset) arg; caller changed.
12761 Don't assume EMACS_INT alignment is the same as pointer alignment.
12763 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
12765 * keyboard.c (read_key_sequence_remapped): New var.
12766 (read_key_sequence): Compute remapping in the right buffer.
12767 (command_loop_1): Use read_key_sequence's remapping directly.
12769 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
12771 * dired.c (file_name_completion): Don't expand file name.
12772 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
12773 before checking file name handler.
12775 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
12776 they've been requested explicitly (bug#9591).
12778 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
12780 * keymap.c (Fsingle_key_description): Use make_specified_string
12781 instead of build_string to build string from push_key_description.
12784 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
12786 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
12787 This fixes a Y2038 bug on 64-bit hosts.
12788 * buffer.c (reset_buffer):
12789 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
12790 (Fclear_buffer_auto_save_failure):
12791 Use 0, not -1, to represent an unset failure time, since time_t
12792 might not be signed.
12794 Remove dependency on glibc malloc internals.
12795 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12796 Move back here from lisp.h, but with their new implementations.
12797 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
12798 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
12799 * charset.c (charset_table_init): New static var.
12800 (syms_of_charset): Use it instead of xmalloc. This removes a
12801 dependency on glibc malloc internals. See Eli Zaretskii's comment in
12802 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
12803 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12804 Move back to alloc.c.
12805 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
12806 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
12808 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
12810 * nsterm.m (windowDidResize): Call x_set_window_size only when
12811 ns_in_resize is true. Otherwise set pixelwidth/height and
12812 call change_frame_size (Bug#9628).
12814 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
12816 Port --enable-checking=all to Fedora 14 x86-64.
12817 * charset.c (syms_of_charset): Also account for glibc malloc's
12818 internal overhead when calculating the initial malloc maximum.
12820 Port --enable-checking=all to Fedora 14 x86.
12821 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12823 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
12824 (overrun_check_realloc, overrun_check_free):
12825 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
12826 That way, xmalloc returns a properly-aligned pointer even if
12827 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
12828 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
12829 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
12830 into account when calculating the initial malloc maximum.
12831 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12832 Move here from alloc.c, so that charset.c can use it too.
12833 Properly align; the old code wasn't right for common 32-bit hosts
12834 when configured with --enable-checking=all.
12835 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
12836 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
12838 2011-09-29 Eli Zaretskii <eliz@gnu.org>
12840 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
12843 2011-09-28 Eli Zaretskii <eliz@gnu.org>
12845 * xdisp.c (compute_display_string_end): If there's no display
12846 string at CHARPOS, return -1.
12848 * bidi.c (bidi_fetch_char): When compute_display_string_end
12849 returns a negative value, treat the character as a normal
12850 character not covered by a display string. (Bug#9624)
12852 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
12854 * lread.c (Fread_from_string): Fix typo in docstring.
12856 2011-09-27 Eli Zaretskii <eliz@gnu.org>
12858 * xdisp.c (handle_invisible_prop): If invisible text ends on a
12859 newline, reseat the iterator instead of bidi-iterating there one
12860 character at a time. (Bug#9610)
12861 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
12862 TO_CHARPOS if the bidi iterator is at base embedding level.
12864 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
12866 * lread.c (readevalloop): Use correct code for NBSP.
12867 (read1): Likewise. (Bug#9608)
12869 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
12871 * dbusbind.c (Fdbus_register_signal): When service is not
12872 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
12874 2011-09-25 Glenn Morris <rgm@gnu.org>
12876 * buffer.c (truncate-lines): Doc fix.
12878 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
12880 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
12881 (Fset_window_next_buffers): Doc fix.
12883 2011-09-24 Glenn Morris <rgm@gnu.org>
12885 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
12887 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
12889 Fix minor problems found by static checking.
12890 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
12891 * indent.c (Fvertical_motion): Fix == vs = typo.
12893 2011-09-24 Eli Zaretskii <eliz@gnu.org>
12895 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
12896 Default value is now t. Doc fix.
12898 * indent.c (Fvertical_motion): Compute and apply the overshoot
12899 logic when moving up, not only when moving down. Fix the
12900 confusing name and values of the it_overshoot_expected variable;
12901 logic changes accordingly. (Bug#9254) (Bug#9549)
12903 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
12904 CHARPOS is covered by a display string which includes newlines.
12905 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
12906 is covered by a display string with embedded newlines.
12908 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
12910 * dbusbind.c (Fdbus_register_signal): Add match rule to
12911 Vdbus_registered_objects_table. (Bug#9581)
12912 (Fdbus_register_method, Vdbus_registered_objects_table):
12915 2011-09-24 Jim Meyering <meyering@redhat.com>
12917 do not ignore write error for any output size
12918 The previous change was incomplete.
12919 While it makes emacs --batch detect the vast majority of stdout
12920 write failures, errors were still ignored whenever the output size is
12921 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
12922 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
12923 && echo FAIL: ignored write error
12924 FAIL: ignored write error
12925 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
12926 && echo FAIL: ignored write error
12927 FAIL: ignored write error
12928 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
12930 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
12932 * emacs.c (Fkill_emacs): In noninteractive mode exit
12933 non-successfully if a write error occurred on stdout. (Bug#9574)
12935 2011-09-21 Eli Zaretskii <eliz@gnu.org>
12937 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
12940 * dispextern.h (struct it): Update the comment documenting what
12943 2011-09-20 Eli Zaretskii <eliz@gnu.org>
12945 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
12946 a display string, extend search for cursor position to end of row.
12947 (find_row_edges): If the row ends in a newline from a display
12948 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
12949 Handle the case of a display string with multiple newlines.
12950 (Fcurrent_bidi_paragraph_direction): Fix search for previous
12951 non-empty line. Fixes confusing cursor motion with arrow keys at
12952 the beginning of a line that starts with whitespace.
12954 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
12956 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
12959 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
12961 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
12962 boolean (Bug#9154).
12964 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12966 * xdisp.c (display_line): Record maximum and minimum buffer
12967 positions even if no glyphs were produced (e.g., by a zero-width
12968 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
12969 buffer positions that will be removed from the glyph row because
12971 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
12972 column is beyond frame width: don't subtract 1 "pixel" when
12973 computing width of the stretch.
12974 (reseat_at_next_visible_line_start): Undo the change made on
12975 2011-09-17 that saved paragraph information and restored it after
12976 the call to `reseat'. (Bug#9545)
12978 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12980 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
12981 and turn window cursor on if cleared (Bug#9415).
12983 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
12985 * search.c (boyer_moore): Take unibyte characters from pattern
12986 literally. (Bug#9458)
12988 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12990 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
12992 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
12994 Fix minor problem found by static checking.
12995 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
12996 initialized, to pacify gcc -Wuninitialized.
12998 * fileio.c: Report proper errno when syscall falls.
12999 (Finsert_file_contents): Save and restore errno,
13000 so that report_file_error outputs the correct diagnostic.
13001 (Fwrite_region) [CLASH_DETECTION]: Likewise.
13003 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13005 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
13007 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13009 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
13010 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
13012 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13014 * xdisp.c (reseat_at_next_visible_line_start): Keep information
13015 about the current paragraph and restore it after the call to reseat.
13017 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
13018 (bidi_find_paragraph_start): Search back for paragraph beginning
13019 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
13020 (bidi_move_to_visually_next): Only trigger paragraph-related
13021 computations when the last character is a newline or at EOB, not
13022 just any NEUTRAL_B. (Bug#9470)
13024 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
13025 truncated lines if point is covered by a display string. (Bug#9524)
13027 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
13029 * xselect.c: Relax test for outgoing X longs (Bug#9498).
13030 (cons_to_x_long): New function.
13031 (lisp_data_to_selection_data): Use it. Correct the test for
13032 short-versus-long data; it was negated. Break out of vector
13033 loop, for efficiency, when a long datum is discovered.
13035 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
13037 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
13039 2011-09-16 Eli Zaretskii <eliz@gnu.org>
13041 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
13042 GCC PR/17406) by declaring this function with external scope.
13044 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13046 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
13047 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
13049 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
13051 * editfns.c (Fformat): Correctly handle text properties on "%%".
13053 2011-09-15 Eli Zaretskii <eliz@gnu.org>
13055 * xterm.c (x_draw_composite_glyph_string_foreground):

13057 * term.c (encode_terminal_code):
13058 * composite.c (composition_update_it, get_composition_id):
13059 * xdisp.c (get_next_display_element)
13060 (fill_composite_glyph_string): Add comments about special meaning
13061 of TAB characters in a composition.
13063 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13065 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
13066 This occurs when processing a multibyte format.
13067 Problem reported by Wolfgang Jenker.
13069 2011-09-15 Johan Bockgård <bojohan@gnu.org>
13071 * xdisp.c (try_cursor_movement): Only check for exact match if
13072 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
13074 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13076 Remove unused external symbols.
13077 * dispextern.h (calc_pixel_width_or_height): Remove decl.
13078 * xdisp.c (calc_pixel_width_or_height): Now static.
13079 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
13080 * indent.c (check_display_width):
13081 * w32term.c: Fix comment to match code.
13082 * xterm.c, xterm.h (x_catching_errors): Remove.
13084 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13086 * xselect.c: Use signed conversions more consistently (Bug#9498).
13087 (selection_data_to_lisp_data): Assume incoming selection data are
13088 signed integers, not unsigned. This is to be consistent with
13089 outgoing selection data, which was modified to use signed integers
13090 in as part of the fix to Bug#9196 in response to Jan D.'s comment
13091 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
13092 expects long, not unsigned long.
13094 2011-09-14 Eli Zaretskii <eliz@gnu.org>
13096 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
13097 computation of loop end. Reported by Johan Bockgård
13100 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
13102 * frame.c (Fother_visible_frames_p): Function deleted.
13104 2011-09-12 Eli Zaretskii <eliz@gnu.org>
13106 * indent.c (compute_motion): Process display vector front to back
13107 rather than the other way around. (Bug#2496)
13109 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
13111 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
13113 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
13115 * minibuf.c (Fread_from_minibuffer): Doc fix.
13117 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13119 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
13120 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
13122 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
13124 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
13125 value for non-existent files.
13127 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13129 * fileio.c (Finsert_file_contents): If the file cannot be opened,
13130 set its "size" to -1. This will set the modtime_size field of
13131 the corresponding buffer to -1, which is what
13132 verify-visited-file-modtime expects for files that do not exist.
13135 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
13137 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
13139 * lisp.h: ... from here. push_key_description is no longer
13140 defined in keyboard.c, so its declaration should not be in
13141 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
13142 logically belongs with push_key_description.
13144 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
13146 * buffer.h: Include <sys/types.h> instead of <time.h>.
13147 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
13148 Problem reported by Herbert J. Skuhra.
13150 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
13152 * xml.c (parse_region): Make the parsing work for
13153 non-comment-starting XML files again (bug#9144).
13155 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
13157 * image.c (gif_load): Fix calculation of bottom and right corner.
13160 2011-09-10 Eli Zaretskii <eliz@gnu.org>
13162 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
13163 redisplay in small windows.
13165 2011-09-09 Eli Zaretskii <eliz@gnu.org>
13167 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
13169 2011-09-08 Martin Rudalics <rudalics@gmx.at>
13171 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
13172 Operate on live windows only.
13174 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
13176 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
13178 2011-09-07 Eli Zaretskii <eliz@gnu.org>
13180 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
13181 only under bidi iteration.
13183 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
13185 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
13187 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13189 isnan: Fix porting problem to Solaris 10 with bundled gcc.
13190 Without this fix, the command to link temacs failed due to an
13191 undefined symbol __builtin_isnan. This is because
13192 /usr/include/iso/math_c99.h #defines isnan(x) to
13193 __builtin_isnan(x), but the bundled gcc, which identifies itself
13194 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
13196 * floatfns.c (isnan): #undef, and then #define to a clone of
13198 (Fisnan): Always define, since it's always available now.
13199 (syms_of_floatfns): Always define isnan at the Lisp level.
13201 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13203 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
13205 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13207 * fileio.c: Fix bugs with large file offsets (Bug#9428).
13208 The previous code assumed that file offsets (off_t values) fit in
13209 EMACS_INT variables, which is not true on typical 32-bit hosts.
13210 The code messed up by falsely reporting buffer overflow in cases
13211 such as (insert-file-contents "big" nil 1 2) into an empty buffer
13212 when "big" contains more than 2**29 bytes, even though this
13213 inserts just one byte and does not overflow the buffer.
13214 (Finsert_file_contents): Store file offsets as off_t
13215 values, not as EMACS_INT values. Check for overflow when
13216 converting between EMACS_INT and off_t. When checking for
13217 buffer overflow or for overlap, take the offsets into account.
13218 Don't use EMACS_INT for small values where int suffices.
13219 When checking for overlap, fix a typo: ZV was used where
13220 ZV_BYTE was intended.
13221 (Fwrite_region): Don't assume off_t fits into 'long'.
13222 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
13224 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
13226 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
13228 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13230 sprintf-related integer and memory overflow issues (Bug#9412).
13232 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
13233 (esprintf, exprintf, evxprintf): New functions.
13234 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
13235 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
13236 (modify_event_symbol): Do not assume that the length of
13237 name_alist_or_stem is safe to alloca and fits in int.
13238 (Fexecute_extended_command): Likewise for function name and binding.
13239 (Frecursion_depth): Wrap around reliably on integer overflow.
13240 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
13241 since some callers pass EMACS_INT values.
13242 (Fsingle_key_description): Don't crash if symbol name contains more
13243 than MAX_ALLOCA bytes.
13244 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
13245 (get_minibuffer): Arg is now EMACS_INT, not int.
13246 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
13247 (esprintf, exprintf, evxprintf): New decls.
13248 * window.h (command_loop_level, minibuf_level): Reflect API changes.
13250 * dbusbind.c (signature_cat): New function.
13251 (xd_signature, Fdbus_register_signal):
13252 Do not overrun buffer; instead, report string overflow.
13254 * dispnew.c (add_window_display_history): Don't overrun buffer.
13255 Truncate instead; this is OK since it's just a log.
13257 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
13258 even if the time zone offset is outlandishly large.
13259 Don't mishandle offset == INT_MIN.
13261 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
13262 when creating daemon; the previous buffer-overflow check was incorrect.
13264 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
13265 which has the guts of the old verror function.
13267 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
13268 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
13270 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
13271 (font_unparse_xlfd): Don't blindly alloca long strings.
13272 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
13273 fits in int, when using sprintf. Use single snprintf to count
13274 length of string rather than counting it via multiple sprintfs;
13275 that's simpler and more reliable.
13276 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
13277 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
13278 sprintf, in case result does not fit in int.
13280 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
13281 (fontset_from_font): Print it.
13283 * frame.c (tty_frame_count): Now printmax_t, not int.
13284 (make_terminal_frame, set_term_frame_name): Print it.
13285 (x_report_frame_params): In X, window IDs are unsigned long,
13286 not signed long, so print them as unsigned.
13287 (validate_x_resource_name): Check for implausibly long names,
13288 and don't assume name length fits in 'int'.
13289 (x_get_resource_string): Don't blindly alloca invocation name;
13290 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
13293 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
13294 (xg_check_special_colors, xg_set_geometry):
13295 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
13297 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
13298 Use esprintf, not sprintf, in case result does not fit in int.
13300 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13301 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
13302 it as a large positive number.
13303 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
13304 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13306 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
13307 in case result does not fit in int.
13309 * print.c (float_to_string): Detect width overflow more reliably.
13310 (print_object): Make sprintf buffer a bit bigger, to avoid potential
13311 buffer overrun. Don't assume list length fits in 'int'. Treat
13312 print length of 0 as 0, not as infinity; to be consistent with other
13313 uses of print length in this function. Don't overflow print length
13314 index. Don't assume hash table size fits in 'long', or that
13315 vectorlike size fits in 'unsigned long'.
13317 * process.c (make_process): Use printmax_t, not int, to format
13318 process-name gensyms.
13320 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
13322 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
13323 to avoid potential buffer overrun.
13325 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
13326 if X resource line is longer than 512 bytes.
13328 * xfns.c (x_window): Make sprintf buffer a bit bigger
13329 to avoid potential buffer overrun.
13331 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
13333 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
13335 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13337 Integer overflow fixes for scrolling, etc.
13338 Without these, Emacs silently mishandles large integers sometimes.
13339 For example, "C-u 4294967297 M-x recenter" was treated as if
13340 it were "C-u 1 M-x recenter" on a typical 64-bit host.
13342 * xdisp.c (try_window_id): Check Emacs fixnum range before
13343 converting to 'int'.
13345 * window.c (window_scroll_line_based, Frecenter):
13346 Check that an Emacs fixnum is in range before assigning it to 'int'.
13347 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
13348 values converted from Emacs fixnums.
13349 (Frecenter): Don't wrap around a line count if it is out of 'int'
13350 range; instead, treat it as an extreme value.
13351 (Fset_window_configuration, compare_window_configurations):
13352 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
13354 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
13355 that can exceed INT_MAX. Check that EMACS_INT value is in range
13356 before assigning it to the (possibly-narrower) index.
13357 (match_limit): Don't assume that a fixnum can fit in 'int'.
13359 * print.c (print_object): Use ptrdiff_t, not int, for index that can
13362 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
13363 (Fvertical_motion): Don't wrap around LINES values that don't fit
13364 in 'int'. Instead, treat them as extreme values. This is good
13365 enough for windows, which can't have more than INT_MAX lines anyway.
13367 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
13369 * Require libxml/parser.h to avoid compilation warning.
13371 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
13373 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
13374 since this reportedly can destroy thread storage.
13376 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
13378 * syntax.c (find_defun_start): Update all cache variables if
13379 exiting early (Bug#9401).
13381 2011-08-30 Eli Zaretskii <eliz@gnu.org>
13383 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
13385 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
13386 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
13387 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
13389 * term.c (tty_append_glyph): New function.
13390 (produce_stretch_glyph): Static function and its prototype deleted.
13392 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
13395 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
13397 * image.c (parse_image_spec): Check for nonnegative, not for positive,
13398 when checking :margin (Bug#9390).
13399 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
13400 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
13401 so that the name doesn't mislead. All uses changed.

13413 the first character in the line after the newline.
13415 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
13417 * ccl.c: Improve and simplify overflow checking (Bug#9196).
13418 (ccl_driver): Do not generate an out-of-range pointer.
13419 (Fccl_execute_on_string): Remove unnecessary check for
13420 integer overflow, noted by Stefan Monnier in
13421 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
13422 Remove a FIXME that didn't need fixing.
13423 Simplify the newly-introduced buffer reallocation code.
13425 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
13427 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
13429 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
13431 Integer and memory overflow issues (Bug#9196).
13433 * doc.c (get_doc_string): Rework so that
13434 get_doc_string_buffer_size is the actual buffer size, rather than
13435 being 1 less than the actual buffer size; this makes xpalloc more
13438 * image.c (x_allocate_bitmap_record, cache_image):
13439 * xselect.c (Fx_register_dnd_atom):
13440 Simplify previous changes by using xpalloc.
13442 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
13443 since either will do and ptrdiff_t is convenient with xpalloc.
13445 * charset.c (charset_table_size)
13446 (struct charset_sort_data.priority): Now ptrdiff_t.
13447 (charset_compare): Don't overflow if priorities differ greatly.
13448 (Fsort_charsets): Don't assume list length fits in int.
13449 Check for size-calculation overflow when allocating sort data.
13450 (syms_of_charset): Allocate an initial charset table that is
13451 just under 64 KiB, to avoid problems with glibc malloc and mmap.
13453 * cmds.c (internal_self_insert): Check for size-calculation overflow.
13455 * composite.h (struct composition.glyph_len): Now int, not unsigned.
13456 The actual value is always <= INT_MAX, and leaving it unsigned made
13457 overflow checking harder.
13459 * dispextern.h (struct glyph_matrix.rows_allocated)
13460 (struct face_cache.size): Now ptrdiff_t, for convenience in use
13461 with xpalloc. The values are still always <= INT_MAX.
13463 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
13465 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
13466 (SAFE_NALLOCA): New macro.
13468 * region-cache.c (struct boundary.pos, find_cache_boundary)
13469 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
13470 (set_cache_region, invalidate_region_cache)
13471 (revalidate_region_cache, know_region_cache, region_cache_forward)
13472 (region_cache_backward, pp_cache):
13473 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
13474 so that ptrdiff_t * can be passed to xpalloc.
13475 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
13476 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
13477 (pp_cache): Don't assume cache_len fits in int.
13478 * region-cache.h: Adjust extern decls to match.

13481 EMACS_INT, since either will do, for xpalloc.
13483 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
13484 (xnmalloc, xnrealloc, xpalloc): New functions.
13486 * bidi.c (bidi_shelve_header_size): New constant.
13487 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
13488 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
13490 * bidi.c (bidi_cache_shrink):
13491 * buffer.c (overlays_at, overlays_in, record_overlay_string)
13493 Don't update size of array until after memory allocation succeeds,
13494 because xmalloc/xrealloc may not return.
13495 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
13496 now that we have proper integer overflow checking.
13497 (record_overlay_string, overlay_strings): Catch overflows when
13498 calculating size of overlay_str_buf.
13500 * callproc.c (Fcall_process): Check for size overflow when
13501 calculating size of args2.
13502 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
13503 Normally we prefer signed values, but sticking with ptrdiff_t would
13504 require adding more-complicated checks.
13506 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
13507 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
13508 Redo buffer-overflow calculations to avoid integer overflow.
13509 Add a FIXME comment where memory seems to be over-allocated.
13511 * character.c (Fstring): Check for size-calculation overflow.
13513 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
13514 unnecessary integer overflow. Check for size overflow.
13515 (encode_coding_object): Don't update size until xmalloc succeeds.
13517 * composite.c (get_composition_id): Check for overflow in glyph
13518 length calculations.
13520 Integer and memory overflow fixes for display code.
13521 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
13522 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
13523 (scrolling_window): Check for overflow in size calculations.

13535 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
13536 (get_doc_string): Check for size calculation overflow.
13537 Don't update size until allocation succeeds.
13538 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
13539 EMACS_INT, where ptrdiff_t will do.
13540 (Fsubstitute_command_keys): Check for string overflow.
13542 * editfns.c (set_time_zone_rule): Don't assume environment length
13544 (message_length): Now ptrdiff_t, not int.
13545 (Fmessage_box): Don't update size until allocation succeeds.
13546 Don't assume message length fits in int.
13547 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
13549 * emacs.c (main): Do not reallocate argv, since there is a null at
13550 the end that can be overwritten, and this way there's no need to
13551 worry about size-calculation overflow.
13552 (sort_args): Check for size-calculation overflow.
13554 * eval.c (init_eval_once, grow_specpdl): Don't update size until
13556 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
13558 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
13559 (x_set_scroll_bar_width, x_figure_window_size):
13560 Check for integer overflow.
13561 (x_set_alpha): Do not assume XINT fits in int.
13563 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
13564 This is for the members text_lines, text_cols, total_lines, total_cols,
13565 where the system imposes an 'int' limit.
13567 * fringe.c (Fdefine_fringe_bitmap):
13568 Don't update size until alloc works.
13570 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
13571 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
13573 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
13574 Check for size-calculation overflow.
13575 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
13576 do, as we prefer signed integers.
13577 (id_to_widget.max_size, id_to_widget.used)
13578 (xg_store_widget_in_map, xg_remove_widget_from_map)
13579 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
13580 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
13581 Use and return ptrdiff_t, not int.
13582 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
13583 * gtkutil.h: Change prototypes to match the above.
13585 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
13586 are duplicate now that they've been promoted to lisp.h.
13587 (x_allocate_bitmap_record, x_alloc_image_color)
13588 (make_image_cache, cache_image, xpm_load):

13602 calculations. Don't update size until allocation succeeds.
13603 Redo calculations to avoid overflow.

13632 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
13633 for command line length. Do not attempt to address one before the
13634 beginning of an array, as that's not portable.
13636 * term.c (max_frame_lines): Remove; unused.
13637 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
13639 (encode_terminal_code, calculate_costs): Check for size

13662 Use ptrdiff_t, not int, for sizes.
13663 (Finternal_make_lisp_face, cache_face):
13664 Check for size calculation overflow.
13665 (cache_face): Treat size calculation overflows as if they were
13666 memory exhaustion (the usual treatment), rather than aborting.
13668 * xfns.c (x_encode_text, x_set_name_internal)
13669 (Fx_change_window_property): Use ptrdiff_t, not int, to count
13670 sizes, since they can exceed INT_MAX in size. Check for size

13675 Don't update size until alloc done.
13677 * xrdb.c (get_environ_db): Don't assume path length fits in int,
13678 as sprintf is limited to int lengths.
13680 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
13681 (X_LONG_MIN): New macros.
13682 Use them to make the following changes clearer.
13683 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
13684 This change doesn't affect the value now, but it may help remind
13685 future maintainers not to raise the value too much later.
13686 (SELECTION_QUANTUM): Remove, replacing with ...
13687 (selection_quantum): ... new function, which avoids overflow.
13689 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
13690 assumption that selection length fits in 'int'.

13703 (lisp_data_to_selection_data, x_property_data_to_lisp):

13707 Don't store size until memory allocation succeeds.
13708 (x_get_window_property): Plug memory leak on memory exhaustion.
13709 Don't double-block input; malloc is safe here. Don't assume 2**34
13710 - 4 fits in unsigned long. Add an xassert to check
13711 XGetWindowProperty overflow. Be more careful about overflow
13712 calculations, and distinguish size from memory overflow better.

13714 unsigned int is less than INT_MAX.
13715 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

13717 (lisp_data_to_selection_data): Don't assume that integers
13718 in the range -65535 through -1 fit in an X unsigned short.
13719 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
13720 result parameters unless successful. Rely on cons_to_unsigned
13721 to report problems with elements; the old code wasn't right anyway.
13722 (x_check_property_data): Check for int overflow; we cannot use
13723 a wider type due to X limits.
13724 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

13756 * lisp.h (hash_lookup, hash_put):
13757 * minibuf.c (Ftest_completion):
13758 Use ptrdiff_t for hash table indexes, not int (which is too
13759 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
13760 32-bit --with-wide-int hosts).
13762 * charset.c (Fdefine_charset_internal): Check for integer overflow.
13763 Add a FIXME comment about memory leaks.
13764 (syms_of_charset): Don't assume xmalloc returns.

13771 with outlandish widths.
13772 * character.h (sanitize_tab_width): Rename from sanitize_width,
13773 now that we have two such functions. All uses changed.

13794 exceed limits imposed by XClientMessageEvent, as well as the usual
13795 ptrdiff_t and size_t limits.
13797 * keyboard.c: Overflow, signedness and related fixes.
13798 (make_lispy_movement): Use same integer type in forward decl
13799 that is used in the definition.
13800 (read_key_sequence, keyremap_step):
13801 Change bufsize argument back to int, undoing my 2011-03-30 change.
13802 We prefer signed types, and int is wide enough here.
13803 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
13804 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
13805 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
13806 length, not size_t. Use ptrdiff_t for index, not int.
13807 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
13808 possibility of integer overflow.
13810 Overflow, signedness and related fixes for images.

13836 Prefer int to unsigned where either will do.
13837 (tiff_handler): New function, combining the cores of the
13838 old tiff_error_handler and tiff_warning_handler.
13839 This function is rewritten to use vsnprintf and thereby avoid
13840 stack buffer overflows. It uses only the features of vsnprintf
13841 that are common to both POSIX and native Microsoft.
13842 (tiff_error_handler, tiff_warning_handler): Use it.
13843 (tiff_load, gif_load, imagemagick_load_image):
13844 Don't assume :index value fits in 'int'.

13846 (imagemagick_load_image): Check that crop parameters fit into
13847 the integer types that MagickCropImage accepts. Don't assume
13848 Vimagemagick_render_type has a nonnegative value. Don't assume
13849 size_t fits in 'long'.
13850 (gs_load): Use printmax_t to print the widest integers possible.

13864 (handle_single_display_spec): If the display spec is of the form
13865 `(space ...)', and specifies display in the text area, return 2
13867 (try_cursor_movement): Check for the need to scroll more
13868 accurately, and prefer exact match for point under bidi.
13869 Don't advance `row' beyond the last row of the window.

13890 positioning on the newline at EOL of R2L text within L2R
13891 paragraph, and vice versa.
13892 (try_cursor_movement): Check continued rows, in addition to
13893 continuation rows. Fixes unwarranted scroll when point enters a
13894 continued line of R2L text within an L2R paragraph, or vice versa.
13895 (cursor_row_p): Consider the case of point being equal to
13896 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving

13922 * xdisp.c (redisplay_window): When computing centering_position,
13923 account for the height of the header line. (Bug#8874)
13925 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
13926 instead of CHAR_TO_BYTE. Fixes a crash when a completion
13927 candidate is selected by the mouse, and that candidate has a
13928 composed character under the mouse.
13930 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
13931 coordinates reported by pos-visible-in-window-p for a composed
13932 character in column zero.

13941 consider it a hit if to_charpos is anywhere in the range of the
13942 composed buffer positions.
13944 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
13946 * image.c (gif_load): Don't assume that each subimage has the same
13947 dimensions as the base image. Handle disposal method that is
13948 "undefined" by the gif spec (Bug#9335).
13950 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
13952 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

13958 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
13959 from an Org mode buffer to a Speedbar frame.
13961 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
13962 a composition, take its buffer position from IT->cmp_it.charpos.
13963 Fixes cursor positioning at the beginning of a line that begins
13964 with a composed character.
13966 2011-08-18 Eli Zaretskii <eliz@gnu.org>
13968 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the

13970 in a buffer produced by `describe-categories'.
13972 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
13973 members before the level stack, so they would be saved and
13974 restored when copying iterator state. Fixes incorrect reordering
13975 around TABs covered by display properties.

14112 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
14113 properties. (Bug#9284)

14300 * nsfont.m (nsfont_open): Remove assignment to voffset and
14301 unnecessary vars hshink, expand, hd, full_height, min_height.
14302 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
14304 * nsterm.h (nsfont_info): Remove voffset field.
14306 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
14308 Implement strike-through and overline on NextStep (Bug#8863).
14310 * nsfont.m (nsfont_open): Use underline position provided by font,
14311 instead of hard-coded value of 2.
14312 (nsfont_draw): Call ns_draw_text_decoration instead.
14314 * nsterm.h: Add declaration for ns_draw_text_decoration.
14316 * nsterm.m (ns_draw_text_decoration): New function for drawing
14317 underline, overline, and strike-through.
14318 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
14319 ns_draw_text_decoration. Change treatment of cursor drawing to
14320 accommodate underlining, etc.
14322 2011-07-28 Eli Zaretskii <eliz@gnu.org>
14324 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
14327 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14329 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
14330 Without this fix, if a signal arrives just after memory fills up,
14331 'malloc' might be invoked reentrantly.
14333 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
14334 In other words, assume that every image size is allowed, on non-X
14335 hosts. This assumption is probably wrong, but it lets Emacs compile.
14337 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
14339 * regex.c (re_iswctype): Convert return values to boolean.
14341 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
14343 * xdisp.c (compute_display_string_pos): Don't use cached display
14344 string position if the buffer had its restriction changed.
14347 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14349 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
14351 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14353 Integer signedness and overflow and related fixes. (Bug#9079)
14355 * bidi.c: Integer size and overflow fixes.
14356 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
14357 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
14358 (bidi_cache_find_level_change, bidi_cache_ensure_space)
14359 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
14360 (bidi_find_other_level_edge):
14361 Use ptrdiff_t instead of EMACS_INT where either will do.
14362 This works better on 32-bit hosts configured --with-wide-int.
14363 (bidi_cache_ensure_space): Check for size-calculation overflow.
14364 Use % rather than repeated addition, for better worst-case speed.
14365 Don't set bidi_cache_size until after xrealloc returns, because it
14367 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
14368 (bidi_cache_ensure_space): Also check that the bidi cache size
14369 does not exceed that of the largest Lisp string or buffer. See Eli
14370 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
14372 * alloc.c (__malloc_size_t): Remove.
14373 All uses replaced by size_t. See Andreas Schwab's note
14374 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
14376 * image.c: Improve checking for integer overflow.
14377 (check_image_size): Assume that f is nonnull, since
14378 it is always nonnull in practice. This is one less thing to
14379 worry about when checking for integer overflow later.
14380 (x_check_image_size): New function, which checks for integer
14381 overflow issues inside X.
14382 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
14383 This removes the need for a memory_full check.
14384 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
14385 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
14386 (xbm_read_bitmap_data): Change locals back to 'int', since
14387 their values must fit in 'int'.
14388 (xpm_load_image, png_load, tiff_load):
14389 Invoke x_create_x_image_and_pixmap earlier,
14390 to avoid much needless work if the image is too large.
14391 (tiff_load): Treat overly large images as if
14392 x_create_x_image_and_pixmap failed, not as malloc failures.
14393 (gs_load): Use x_check_image_size.
14395 * gtkutil.c: Omit integer casts.
14396 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
14397 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
14399 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
14401 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
14402 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
14403 would wrongly return t on a 64-bit host.
14405 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
14406 The plain *_OVERFLOW macros run afoul of GCC bug 49705
14407 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
14408 and therefore cause GCC to emit a bogus diagnostic in some cases.
14410 * image.c: Integer signedness and overflow and related fixes.
14411 This is not an exhaustive set of fixes, but it's time to
14412 record what I've got.
14413 (lookup_pixel_color, check_image_size): Remove redundant decls.
14414 (check_image_size): Don't assume that arbitrary EMACS_INT values
14415 fit in 'int', or that arbitrary 'double' values fit in 'int'.
14416 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
14417 (tiff_load, imagemagick_load_image):
14418 Check for overflow in size calculations.
14419 (x_create_x_image_and_pixmap): Remove unnecessary test for
14420 xmalloc returning NULL; that can't happen.
14421 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
14422 (xpm_color_bucket): Use better integer hashing function.
14423 (xpm_cache_color): Don't possibly over-allocate memory.
14424 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
14425 (gif_memory_source):
14426 Use ptrdiff_t, not int or size_t, to record sizes.
14427 (png_load): Don't assume values greater than 2**31 fit in 'int'.
14428 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
14429 either works, as we prefer signed integers.
14430 (tiff_read_from_memory, tiff_write_from_memory):
14431 Return tsize_t, not size_t, since that's what the TIFF API wants.
14432 (tiff_read_from_memory): Don't fail simply because the read would
14433 go past EOF; instead, return a short read.
14434 (tiff_load): Omit no-longer-needed casts.
14435 (Fimagemagick_types): Don't assume size fits into 'int'.
14437 Improve hashing quality when configured --with-wide-int.
14438 * fns.c (hash_string): New function, taken from sxhash_string.
14439 Do not discard information about ASCII character case; this
14440 discarding is no longer needed.
14441 (sxhash-string): Use it. Change sig to match it. Caller changed.
14442 * lisp.h: Declare it.
14443 * lread.c (hash_string): Remove, since we now use fns.c's version.
14444 The fns.c version returns a wider integer if --with-wide-int is
14445 specified, so this should help the quality of the hashing a bit.
14447 * emacs.c: Integer overflow minor fix.
14448 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
14449 Define only if GNU_LINUX.
14450 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
14452 * dispnew.c: Integer signedness and overflow fixes.
14453 Remove unnecessary forward decls, that were a maintenance hassle.
14454 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
14456 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
14457 (scrolling_window): Use ptrdiff_t, not int, for byte count.
14458 (prepare_desired_row, line_draw_cost):
14459 Use int, not unsigned, where either works.
14460 (save_current_matrix, restore_current_matrix):
14461 Use ptrdiff_t, not size_t, where either works.
14462 (init_display): Check for overflow more accurately, and without
14463 relying on undefined behavior.
14465 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
14466 Remove, replacing with the new symbols in lisp.h. All uses changed.
14467 * fileio.c (make_temp_name):
14468 * filelock.c (lock_file_1, lock_file):
14469 * xdisp.c (message_dolog):
14470 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
14471 Use pMd etc. instead.
14472 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
14473 replacing the pWIDE etc. symbols removed from editfns.c.
14475 * keyboard.h (num_input_events): Now uintmax_t.
14476 This is (very slightly) less likely to mess up due to wraparound.
14479 * buffer.c: Integer signedness fixes.
14480 (alloc_buffer_text, enlarge_buffer_text):
14481 Use ptrdiff_t rather than size_t when either will do, as we prefer
14484 * alloc.c: Integer signedness and overflow fixes.
14485 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
14486 (__malloc_size_t): Default to size_t, not to int.
14487 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
14488 (Fgarbage_collect, mark_object_loop_halt, mark_object):
14489 Prefer ptrdiff_t to size_t when either would do, as we prefer
14491 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
14492 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
14493 Now const. Initialize with values that are in range even if char
14495 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
14496 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
14497 These functions do the right thing with sizes > 2**32.
14498 (check_depth): Now ptrdiff_t, not int.
14499 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
14500 Adjust to new way of storing sizes. Check for size overflow bugs
14502 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
14503 slightly wrong anyway, as it missed one instance of
14504 XMALLOC_OVERRUN_CHECK_OVERHEAD.
14505 (refill_memory_reserve): Omit needless cast to size_t.
14506 (mark_object_loop_halt): Mark as externally visible.
14508 * xselect.c: Integer signedness and overflow fixes.
14509 (Fx_register_dnd_atom, x_handle_dnd_message):
14510 Use ptrdiff_t, not size_t, since we prefer signed.
14511 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
14512 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
14513 x_dnd_atoms_size and x_dnd_atoms_length.
14515 * doprnt.c: Prefer signed to unsigned when either works.
14517 * doprnt.c (doprnt):
14519 * xdisp.c (vmessage):
14520 Use ptrdiff_t, not size_t, when using or implementing doprnt,
14521 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
14522 prefer signed arithmetic to avoid comparison confusion.
14523 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
14524 but is a bit tricky.
14526 Assume freestanding C89 headers, string.h, stdlib.h.
14527 * data.c, doprnt.c, floatfns.c, print.c:
14528 Include float.h unconditionally.
14529 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
14530 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
14531 * regex.c: Likewise for stddef.h, string.h.
14532 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
14533 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
14534 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
14535 (STDC_HEADERS): Remove obsolete defines.
14536 * sysdep.c: Include limits.h unconditionally.
14538 Assume support for memcmp, memcpy, memmove, memset.
14539 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
14540 * regex.c (memcmp, memcpy):
14541 Remove; we assume C89 now.
14543 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
14544 (__malloc_safe_bcopy): Remove; no longer needed.
14546 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
14547 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
14548 well either way, and we prefer signed to unsigned.
14550 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
14552 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
14553 closes the connection while we're reading (bug#9182).
14555 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
14557 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
14558 are specified (Bug#9168).
14560 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
14562 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
14563 Found by GCC static checking and --with-wide-int on a 32-bit host.
14565 2011-07-25 Eli Zaretskii <eliz@gnu.org>
14567 * xdisp.c (compute_display_string_pos): Fix logic of caching
14568 previous display string position. Initialize cached_prev_pos to
14569 -1. Fixes slow-down at the beginning of a buffer.
14571 2011-07-24 Eli Zaretskii <eliz@gnu.org>
14573 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
14574 for attrs[LFACE_FONTSET_INDEX].
14576 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
14578 * xml.c (parse_region): Remove unused local
14579 that was recently introduced.
14581 2011-07-23 Eli Zaretskii <eliz@gnu.org>
14583 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
14584 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
14586 * xdisp.c (move_it_in_display_line_to): Record the best matching
14587 position for TO_CHARPOS while scanning the line, and restore it on
14588 exit if none of the characters scanned was an exact match.
14589 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
14590 when exact match is impossible due to invisible text, and the
14591 lines are truncated.
14593 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
14595 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
14598 2011-07-22 Eli Zaretskii <eliz@gnu.org>
14600 Fix a significant slow-down of cursor motion with C-n, C-p,
14601 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
14602 auto-repeat under bidi redisplay in fontified buffers.
14603 * xdisp.c (compute_stop_pos_backwards): New function.
14604 (next_element_from_buffer): Call compute_stop_pos_backwards to
14605 find a suitable prev_stop when we find ourselves before
14607 (reseat): Don't look for prev_stop, as that could mean a very long
14609 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
14610 <cached_disp_overlay_modiff>: Cache for last found display string
14612 (compute_display_string_pos): Return the cached position if asked
14613 about the same buffer in the same area of character positions, and
14614 the buffer wasn't changed since the time the display string
14615 position was cached.
14617 2011-07-22 Eli Zaretskii <eliz@gnu.org>
14619 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
14620 is an integer, which is important for empty lines. (Bug#9149)
14622 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
14624 * frame.c (Fmodify_frame_parameters): In tty case, update the
14625 default face if necessary (Bug#4238).
14627 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
14629 * editfns.c (Fstring_to_char): No need to explain what a character
14630 is in the docstring (Bug#6576).
14632 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
14634 * xml.c (parse_region): Make sure we always return a tree.
14636 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
14638 * xml.c (parse_region): If a document contains only comments,
14641 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
14643 * xml.c (make_dom): Return comments, too.
14645 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
14648 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
14649 and the surrounding thread.
14650 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
14651 rather than fgets, and retry after EINTR. Otherwise, 'emacs
14652 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
14654 * s/openbsd.h (BROKEN_SIGIO): Define.
14655 * unexelf.c (unexec) [__OpenBSD__]:
14656 Don't update the .mdebug section of the Alpha COFF symbol table.
14658 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14660 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
14663 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
14665 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
14666 This fixes some race conditions on the permissions of any newly
14669 * alloc.c (valid_pointer_p): Use pipe, not open.
14670 This fixes some permissions issues when debugging.
14672 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
14673 If fchown fails to set both uid and gid, try to set just gid,
14674 as that is sometimes allowed. Adjust the file's mode to eliminate
14675 setuid or setgid bits that are inappropriate if fchown fails.
14677 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
14679 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
14680 to compare Lisp_Objects.
14681 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
14682 global_gnutls_log_level, don't mistake it for a Lisp_Object.
14683 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
14685 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
14687 * lread.c (read_integer): Unread even EOF character.
14688 (read1): Likewise. Properly record start position of symbol.
14690 * lread.c (read1): Read `#:' as empty uninterned symbol if no
14691 symbol character follows.
14693 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
14695 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
14696 This works around a problem with the previous change to Fcopy_file.
14697 Recent glibc declares fchown with __attribute__((warn_unused_result)),
14698 and without this change, GCC might complain about discarding
14699 fchown's return value.
14701 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
14703 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
14705 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
14707 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
14709 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
14711 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
14712 it's used from the C level.
14714 * process.c: Use the same condition for POLL_FOR_INPUT in both
14715 keyboard.c and process.c (bug#1858).
14717 2011-07-09 Lawrence Mitchell <wence@gmx.li>
14719 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
14720 (Fgnutls_boot): Use it.
14722 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
14724 * doc.c (Fsubstitute_command_keys): Revert last change.
14726 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
14728 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
14729 quotes the next character, and doesn't affect other longer
14730 sequences (bug#8935).
14732 * lread.c (syms_of_lread): Clarify that is isn't only
14733 `eval-buffer' and `eval-defun' that's affected by
14734 `lexical-binding' (bug#8460).
14736 2011-07-15 Eli Zaretskii <eliz@gnu.org>
14738 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
14739 bidi redisplay when a line includes both an image and is truncated.
14741 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
14743 Fix minor problems found by static checking.
14744 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
14745 (elsz): Now a signed constant, not a size_t var. We prefer signed
14746 types to unsigned, to avoid integer comparison confusion. Without
14747 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
14748 "cannot optimize loop, the loop counter may overflow", a symptom
14750 * indent.c (Fvertical_motion): Mark locals as initialized.
14751 * xdisp.c (reseat_to_string): Fix pointer signedness issue.

14768 (compute_display_string_end): Accept additional argument STRING.
14769 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.

14776 buffer position was specified. Initialize paragraph_embedding to
14778 (reseat_to_string): Initialize the bidi iterator.
14779 (display_string): If we need to ignore text properties of
14780 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
14781 original value of -1 will not work with bidi.)

14791 Fix calculation of the object to scan. Fixes an error when using

14794 base_level_stop; instead, set base_level_stop to BEGV.
14795 Fixes crashes in vertical-motion.
14796 (next_element_from_buffer): Improve commentary for when
14797 the iterator is before prev_stop.
14798 (init_iterator): Initialize bidi_p from the default value of
14799 bidi-display-reordering, not from buffer-local value. Use the
14800 buffer-local value only if initializing for buffer iteration.
14801 (handle_invisible_prop): Support invisible properties on strings
14802 that are being bidi-reordered.

14824 (display_menu_bar): Force left-to-right direction. Add a FIXME
14825 comment for making that be controlled by a user option.

14839 pushed the iterator stack, restore the internal state of the bidi
14840 iterator by calling bidi_pop_it same number of times.
14841 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
14842 and we are bidi-iterating, don't decrement the iterator position;
14843 instead, set the first_elt flag in the bidi iterator, to produce
14845 (reseat_1): Remove redundant setting of string_from_display_prop_p.
14846 (push_display_prop): xassert that we are iterating a buffer.

14850 (push_display_prop): Set up the `unibyte' member of bidi_it.string
14851 correctly. Don't assume unibyte strings are not bidi-reordered.

14859 popping after iteration over a string that came from a display
14860 property. Fix a typo in popping stretch info. Add an assertion
14861 for verifying that the iterator position is in sync with the bidi
14863 (handle_single_display_spec, get_overlay_strings_1)

15279 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
15280 New macros, used in the buffer.c change.

15316 Random fixes. E.g., (random) never returned negative values.
15317 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
15318 subseconds part to the entropy, as that's a bit more random.
15319 Prefer signed to unsigned, since the signedness doesn't matter and
15320 in general we prefer signed. When given a limit, use a
15321 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
15322 latter isn't right if USE_2_TAGS_FOR_INTS.
15323 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
15324 not 0..VALMASK. Don't discard "excess" bits that random () returns.

15336 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
15337 This is more efficient than Ffile_directory_p and avoids a minor race.

15341 * buffer.c (Foverlay_put): Say what the return value is
15344 * fileio.c (barf_or_query_if_file_exists): Check first if the file

15348 error be more correct.
15350 * fns.c (Frequire): Remove the mention of the .gz files, since

15364 Qgnutls_bootprop_verify_error (which is no longer used).
15366 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
15367 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
15368 Also (re)move comments that are misplaced or no longer relevant.

15397 * lread.c (syms_of_lread): Mention single symbols defined by

15469 * eval.c (struct backtrace): Simplify and port the data structure.
15470 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
15471 signed bit field, as this assumption is not portable and it makes
15472 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
15473 "char debug_on_exit : 1" as this is not portable either; instead,
15474 use the portable "unsigned int debug_on_exit : 1". Remove unused
15475 member evalargs. Remove obsolete comments about cc bombing out.
15477 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

15635 2011-06-24 Teodor Zlatanov <tzz@lifelogs.com>
15637 * gnutls.c (syms_of_gnutls): Use the DEFSYM macro from character.h.
15639 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
15641 Integer and buffer overflow fixes (Bug#8873).
15643 * print.c (printchar, strout): Check for string overflow.
15644 (PRINTPREPARE, printchar, strout):
15645 Don't set size unless allocation succeeds.
15647 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
15648 for sizes. Check for string overflow more accurately.
15649 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
15651 * macros.c: Integer and buffer overflow fixes.
15652 * keyboard.h (struct keyboard.kbd_macro_bufsize):
15653 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
15654 Use ptrdiff_t, not int, for sizes.
15655 Don't increment bufsize until after realloc succeeds.
15656 Check for size-calculation overflow.
15657 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
15659 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
15661 * lread.c: Integer overflow fixes.
15662 (read_integer): Radix is now EMACS_INT, not int,
15663 to improve quality of diagnostics for out-of-range radices.
15664 Calculate buffer size correctly for out-of-range radices.
15665 (read1): Check for integer overflow in radices, and in
15666 read-circle numbers.
15667 (read_escape): Avoid int overflow.
15668 (Fload, openp, read_buffer_size, read1)
15669 (substitute_object_recurse, read_vector, read_list, map_obarray):
15670 Use ptrdiff_t, not int, for sizes.
15671 (read1): Use EMACS_INT, not int, for sizes.
15672 Check for size overflow.
15674 * image.c (cache_image): Check for size arithmetic overflow.
15676 * lread.c: Integer overflow issues.
15677 (saved_doc_string_size, saved_doc_string_length)
15678 (prev_saved_doc_string_size, prev_saved_doc_string_length):
15679 Now ptrdiff_t, not int.

15681 out-of-range doc string lengths.
15682 (read_list): Don't assume file position fits in int.
15683 (read_escape): Check for hex character overflow.
15685 2011-06-22 Leo Liu <sdl.web@gmail.com>
15687 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
15688 Move to minibuffer.el.
15690 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
15692 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
15693 The following patches are for when GLYPH_DEBUG && !XASSERT.
15694 * dispextern.h (trace_redisplay_p, dump_glyph_string):
15695 * dispnew.c (flush_stdout):
15696 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
15697 Mark as externally visible.
15698 * dispnew.c (check_window_matrix_pointers): Now static.
15699 * dispnew.c (window_to_frame_vpos):
15700 * xfns.c (unwind_create_frame):
15701 * xterm.c (x_check_font): Remove unused local.
15702 * scroll.c (CHECK_BOUNDS):
15703 * xfaces.c (cache_fache): Rename local to avoid shadowing.
15704 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
15705 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
15706 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
15707 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
15709 (debug_method_add): Use va_list and vsprintf rather than relying
15710 on undefined behavior with wrong number of arguments.
15711 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
15712 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
15713 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
15714 since we're not interested in debugging glyphs with old libraries.
15715 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
15716 GCC 4.6.0's static checking.
15718 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
15720 Integer overflow and signedness fixes (Bug#8873).

15729 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
15730 (x_create_bitmap_from_xpm_data):
15731 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
15732 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
15734 * xfaces.c (load_pixmap):
15735 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
15736 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
15737 (.bitmaps_last, struct x_output.icon_bitmap):
15738 Use ptrdiff_t, not int, for bitmap indexes.
15739 (x_allocate_bitmap_record): Check for size overflow.
15740 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
15742 Use ptrdiff_t, not int, for overlay counts.
15743 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
15744 * editfns.c (overlays_around, get_pos_property):
15745 * textprop.c (get_char_property_and_overlay):
15746 * xdisp.c (next_overlay_change, note_mouse_highlight):
15747 * xfaces.c (face_at_buffer_position):
15748 * buffer.c (OVERLAY_COUNT_MAX): New macro.
15749 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
15750 (Fnext_overlay_change, Fprevious_overlay_change)
15751 (mouse_face_overlay_overlaps, Foverlays_in):
15752 Use ptrdiff_t, not int, for sizes.
15753 (overlays_at, overlays_in): Check for size-calculation overflow.
15755 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
15757 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
15758 (x_session_initialize): Do not assume string length fits in int.
15760 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
15761 This is unlikely, but can occur if DPI is outlandish.
15763 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
15764 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
15766 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
15767 * xrdb.c (magic_file_p, search_magic_path):
15768 Omit last arg SUFFIX; it was always 0. All callers changed.
15769 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
15771 * xfont.c (xfont_match): Avoid need for strlen.
15773 * xfns.c: Don't assume strlen fits in int.
15774 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
15776 * xdisp.c (message_log_check_duplicate): Return intmax_t,
15777 not unsigned long, as we prefer signed integers. All callers changed.
15778 Detect integer overflow in repeat count.
15779 (message_dolog): Don't assume print length fits in 39 bytes.
15780 (display_mode_element): Don't assume strlen fits in int.
15782 * termcap.c: Don't assume sizes fit in int and never overflow.
15783 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
15784 (gobble_line): Check for size-calculation overflow.
15786 * minibuf.c (Fread_buffer):
15787 * lread.c (intern, intern_c_string):
15788 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
15789 Don't assume string length fits in int.
15791 * keyboard.c (parse_tool_bar_item):
15792 * gtkutil.c (style_changed_cb): Avoid need for strlen.
15794 * font.c: Don't assume string length fits in int.
15795 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
15796 Use ptrdiff_t, not int.
15797 (font_intern_prop): Don't assume string length fits in int.
15798 Don't assume integer property fits in fixnum.
15799 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
15801 * filelock.c: Fix some buffer overrun and integer overflow issues.
15802 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
15803 Reformulate so as not to need the command string.
15804 Invoke gzip -cd rather than gunzip, as it's more portable.
15805 (lock_info_type, lock_file_1, lock_file):
15806 Don't assume pid_t and time_t fit in unsigned long.
15807 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
15808 (current_lock_owner): Prefer signed type for sizes.
15809 Use memcpy, not strncpy, where memcpy is what is really wanted.
15810 Don't assume (via atoi) that time_t and pid_t fit in int.
15811 Check for time_t and/or pid_t out of range, e.g., via a network share.
15812 Don't alloca where an auto var works fine.
15814 * fileio.c: Fix some integer overflow issues.
15815 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
15816 Don't assume string length fits in int.
15817 (directory_file_name): Don't assume string length fits in long.
15818 (make_temp_name): Don't assume pid fits in int, or that its print
15819 length is less than 20.
15821 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
15823 * coding.c (make_subsidiaries): Don't assume string length fits in int.
15825 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
15827 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
15828 We prefer signed integers, even for size calculations.
15830 * emacs.c: Don't assume string length fits in 'int'.
15831 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
15832 (main): Don't invoke strlen when not needed.
15834 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
15835 (XD_DEBUG_MESSAGE): Don't waste a byte.
15837 * callproc.c (getenv_internal_1, getenv_internal)
15838 (Fgetenv_internal):
15839 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
15841 * lread.c (invalid_syntax): Omit length argument.
15842 All uses changed. This doesn't fix a bug, but it simplifies the
15843 code away from its former Hollerith-constant appearance, and it's
15844 one less 'int' to worry about when looking at integer-overflow issues.
15845 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
15847 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
15848 This didn't break anything, but it didn't help either.
15849 It's confusing to put a bogus integer in a place where the actual
15850 value does not matter.
15851 (LIST_END_P): Remove unused macro and its bogus comment.
15852 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
15854 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
15855 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
15857 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
15858 We prefer signed types, and the value cannot exceed the EMACS_INT
15859 range anyway (because otherwise the length would not be representable).
15860 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
15861 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
15862 This avoids a GCC warning when WIDE_EMACS_INT.
15864 * indent.c (sane_tab_width): New function.
15865 (current_column, scan_for_column, Findent_to, position_indentation)
15866 (compute_motion): Use it. This is just for clarity.
15867 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
15869 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
15871 * lisp.h (lint_assume): New macro.
15872 * composite.c (composition_gstring_put_cache):
15873 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
15875 * editfns.c, insdel.c:
15876 Omit unnecessary forward decls, to simplify future changes.
15878 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
15880 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
15882 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
15883 Use much-faster test for byte-length change.
15884 Don't assume string byte-length fits in 'int'.
15885 Check that character arg fits in 'int'.
15886 (mapcar1): Declare byte as byte, for clarity.
15888 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
15890 * fns.c (concat): Catch string overflow earlier.
15891 Do not rely on integer wraparound.
15893 * dispextern.h (struct it.overlay_strings_charpos)
15894 (struct it.selective): Now EMACS_INT, not int.
15895 * xdisp.c (forward_to_next_line_start)
15896 (back_to_previous_visible_line_start)
15897 (reseat_at_next_visible_line_start, next_element_from_buffer):
15898 Don't arbitrarily truncate the value of 'selective' to int.
15900 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
15902 * composite.c: Don't truncate sizes to 'int'.
15903 (composition_gstring_p, composition_reseat_it)
15904 (composition_adjust_point): Use EMACS_INT, not int.
15905 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
15906 not EMACS_UINT, for indexes.
15908 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
15910 * buffer.c: Include <verify.h>.
15911 (struct sortvec.priority, struct sortstr.priority):
15912 Now EMACS_INT, not int.
15913 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
15914 (struct sortstr.size, record_overlay_string)
15915 (struct sortstrlist.size, struct sortlist.used):
15916 Don't truncate size to int.
15917 (record_overlay_string): Check for size-calculation overflow.
15918 (init_buffer_once): Check at compile-time, not run-time.
15920 2011-06-22 Jim Meyering <meyering@redhat.com>
15922 Don't leak an XBM-image-sized buffer
15923 * image.c (xbm_load): Free the image buffer after using it.
15925 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
15928 * composite.c (find_automatic_composition): Omit needless 'return 0;'
15929 that Sun C diagnosed.
15930 * fns.c (secure_hash): Fix pointer signedness issue.
15931 * intervals.c (static_offset_intervals): New function.
15932 (offset_intervals): Use it.
15934 2011-06-21 Leo Liu <sdl.web@gmail.com>
15937 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
15940 * fns.c (secure_hash): Rename from crypto_hash_function and change
15941 the first arg to accept symbols.
15942 (Fsecure_hash): New primitive.
15943 (syms_of_fns): New symbols.
15945 2011-06-20 Deniz Dogan <deniz@dogan.se>
15947 * process.c (Fset_process_buffer): Clarify return value in
15950 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
15952 * dispnew.c (add_window_display_history): Use BVAR.
15954 * xdisp.c (debug_method_add): Use BVAR.
15955 (check_window_end, dump_glyph_matrix, dump_glyph)
15956 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
15958 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
15961 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
15962 check till after the cache is created in init_frame_faces.
15964 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
15966 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
15968 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
15970 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
15971 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
15972 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
15974 Improve buffer-overflow checking (Bug#8873).
15975 * fileio.c (Finsert_file_contents):
15976 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
15977 Remove the old (too-loose) buffer overflow checks.
15978 They weren't needed, since make_gap checks for buffer overflow.
15979 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
15980 The old code merely checked for Emacs fixnum overflow, and relied
15981 on undefined (wraparound) behavior. The new code avoids undefined
15982 behavior, and also checks for ptrdiff_t and/or size_t overflow.
15984 * editfns.c (Finsert_char): Don't dump core with very negative counts.
15985 Tune. Don't use wider integers than needed. Don't use alloca.
15986 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
15988 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
15990 * insdel.c, lisp.h (buffer_overflow): New function.
15991 (insert_from_buffer_1, replace_range, replace_range_2):
15992 * insdel.c (make_gap_larger):
15993 * editfns.c (Finsert_char):
15994 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
15996 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
15998 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
16000 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
16002 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
16003 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
16005 * fileio.c: Don't assume EMACS_INT fits in off_t.
16006 (emacs_lseek): New static function.
16007 (Finsert_file_contents, Fwrite_region): Use it.
16008 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
16010 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
16012 * fns.c: Don't overflow int when computing a list length.
16013 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
16014 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
16015 truncation on 64-bit hosts. Check for QUIT every
16016 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
16017 faster and is responsive enough.
16018 (Flength): Report an error instead of overflowing an integer.
16019 (Fsafe_length): Return a float if the value is not representable
16020 as a fixnum. This shouldn't happen except in contrived situations.
16021 (Fnthcdr, Fsort): Don't assume list length fits in int.
16022 (Fcopy_sequence): Don't assume vector length fits in int.
16024 * alloc.c: Check that resized vectors' lengths fit in fixnums.
16025 (header_size, word_size): New constants.
16026 (allocate_vectorlike): Don't check size overflow here.
16027 (allocate_vector): Check it here instead, since this is the only
16028 caller of allocate_vectorlike that could cause overflow.
16029 Check that the new vector's length is representable as a fixnum.
16031 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
16032 The previous code was bogus. For example, next_almost_prime (32)
16033 returned 39, which is undesirable as it is a multiple of 3; and
16034 next_almost_prime (24) returned 25, which is a multiple of 5 so
16035 why was the code bothering to check for multiples of 7?
16037 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
16039 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
16041 Variadic C functions now count arguments with ptrdiff_t.
16042 This partly undoes my 2011-03-30 change, which replaced int with size_t.
16043 Back then I didn't know that the Emacs coding style prefers signed int.
16044 Also, in the meantime I found a few more instances where arguments
16045 were being counted with int, which may truncate counts on 64-bit
16046 machines, or EMACS_INT, which may be unnecessarily wide.
16047 * lisp.h (struct Lisp_Subr.function.aMANY)
16048 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
16049 Arg counts are now ptrdiff_t, not size_t.
16050 All variadic functions and their callers changed accordingly.
16051 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
16052 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
16053 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
16054 * callint.c (Fcall_interactively): Check arg count for overflow,
16055 to avoid potential buffer overrun. Use signed char, not 'int',
16056 for 'varies' array, so that we needn't bother to check its size
16057 calculation for overflow.
16058 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
16059 * eval.c (apply_lambda):
16060 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
16061 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
16062 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
16064 * callint.c (Fcall_interactively): Don't use index var as event count.
16066 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
16067 * mem-limits.h (SIZE): Remove; no longer used.
16069 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
16071 Remove unnecessary casts.
16072 * xterm.c (x_term_init):
16073 * xfns.c (x_set_border_pixel):
16074 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
16075 These aren't needed now that we assume ANSI C.
16077 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
16078 It's more likely to cause problems (due to unsigned overflow)
16081 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
16083 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
16085 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
16087 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
16089 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
16091 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
16093 GLYPH_CODE_FACE returns EMACS_INT, not int.
16094 * dispextern.h (merge_faces):
16095 * xfaces.c (merge_faces):
16096 * xdisp.c (get_next_display_element, next_element_from_display_vector):
16097 Don't assume EMACS_INT fits in int.
16099 * character.h (CHAR_VALID_P): Remove unused parameter.
16100 * fontset.c, lisp.h, xdisp.c: All uses changed.
16102 * editfns.c (Ftranslate_region_internal): Omit redundant test.
16104 * fns.c (concat): Minor tuning based on overflow analysis.
16105 This doesn't fix any bugs. Use int to hold character, instead
16106 of constantly refetching from Emacs object. Use XFASTINT, not
16107 XINT, for value known to be a character. Don't bother comparing
16108 a single byte to 0400, as it's always less.
16110 * floatfns.c (Fexpt):
16111 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
16113 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
16116 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
16118 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
16119 Without this fix, on a 64-bit host (aset S 0 4294967386) would
16120 incorrectly succeed when S was a string, because 4294967386 was
16121 truncated before it was used.
16123 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
16124 Otherwise, an out-of-range integer could cause undefined behavior
16127 * composite.c: Use int, not EMACS_INT, for characters.
16128 (fill_gstring_body, composition_compute_stop_pos): Use int, not
16129 EMACS_INT, for values that are known to be in character range.
16130 This doesn't fix any bugs but is the usual style inside Emacs and
16131 may generate better code on 32-bit machines.
16133 Make sure a 64-bit char is never passed to ENCODE_CHAR.
16134 This is for reasons similar to the recent CHAR_STRING fix.
16135 * charset.c (Fencode_char): Check that character arg is actually
16136 a character. Pass an int to ENCODE_CHAR.
16137 * charset.h (ENCODE_CHAR): Verify that the character argument is no
16138 wider than 'int', as a compile-time check to prevent future regressions
16141 * character.c (char_string): Remove unnecessary casts.
16143 Make sure a 64-bit char is never passed to CHAR_STRING.
16144 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
16145 by silently ignoring the top 32 bits, allowing some values
16146 that were far too large to be valid characters.
16147 * character.h: Include <verify.h>.
16148 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
16149 arguments are no wider than unsigned, as a compile-time check
16150 to prevent future regressions in this area.
16152 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
16153 (Fsubst_char_in_region):
16155 * xdisp.c (decode_mode_spec_coding):
16156 Adjust to CHAR_STRING's new requirement.
16157 * editfns.c (Finsert_char, Fsubst_char_in_region):
16158 * fns.c (concat): Check that character args are actually
16159 characters. Without this test, these functions did the wrong
16160 thing with wildly out-of-range values on 64-bit hosts.
16162 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
16163 These casts should not be needed on 32-bit hosts, either.
16164 * keyboard.c (read_char):
16165 * lread.c (Fload): Remove casts to unsigned.
16167 * lisp.h (UNSIGNED_CMP): New macro.
16168 This fixes comparison bugs on 64-bit hosts.
16169 (ASCII_CHAR_P): Use it.
16170 * casefiddle.c (casify_object):
16171 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
16172 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
16173 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
16174 * dispextern.h (FACE_FROM_ID):
16175 * keyboard.c (read_char): Use UNSIGNED_CMP.
16177 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
16178 not to EMACS_INT, to avoid GCC warning.
16180 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
16182 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
16183 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
16184 isn't needed on 32-bit machines.
16186 * buffer.c (Fgenerate_new_buffer_name):
16187 Use EMACS_INT for count, not int.
16188 (advance_to_char_boundary): Return EMACS_INT, not int.
16190 * data.c (Qcompiled_function): Now static.
16192 * window.c (window_body_lines): Now static.
16194 * image.c (gif_load): Rename local to avoid shadowing.
16196 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
16197 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
16198 * alloc.c (make_save_value): Integer argument is now of type
16199 ptrdiff_t, not int.
16200 (mark_object): Use ptrdiff_t, not int.
16201 * lisp.h (pD): New macro.
16202 * print.c (print_object): Use it.
16204 * alloc.c: Use EMACS_INT, not int, to count objects.
16205 (total_conses, total_markers, total_symbols, total_vector_size)
16206 (total_free_conses, total_free_markers, total_free_symbols)
16207 (total_free_floats, total_floats, total_free_intervals)
16208 (total_intervals, total_strings, total_free_strings):
16209 Now EMACS_INT, not int. All uses changed.
16210 (Fgarbage_collect): Compute overall total using a double, so that
16211 integer overflow is less likely to be a problem. Check for overflow
16212 when converting back to an integer.
16213 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
16214 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
16215 These were 'int' variables that could overflow on 64-bit hosts;
16216 they were never used, so remove them instead of repairing them.
16217 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
16218 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
16219 Previously, this ceilinged at INT_MAX, but that doesn't work on
16221 (allocate_pseudovector): Don't use EMACS_INT when int would do.
16223 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
16224 (allocate_vectorlike): Check for ptrdiff_t overflow.
16225 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
16226 when a (possibly-narrower) signed value would do just as well.
16227 We prefer using signed arithmetic, to avoid comparison confusion.
16229 * alloc.c: Catch some string size overflows that we were missing.
16230 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
16231 for convenience in STRING_BYTES_MAX.
16232 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
16233 The definition here is exact; the one in lisp.h was approximate.
16234 (allocate_string_data): Check for string overflow. This catches
16235 some instances we weren't catching before. Also, it catches
16236 size_t overflow on (unusual) hosts where SIZE_MAX <= min
16237 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
16238 and ptrdiff_t and EMACS_INT are both 64 bits.
16240 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
16241 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
16242 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
16244 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
16246 * alloc.c (Fmake_string): Check for out-of-range init.
16248 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
16250 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
16252 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
16254 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
16255 xg_get_default_scrollbar_width.
16257 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
16258 (int_gtk_range_get_value): Move to the scroll bar part of the file.
16259 (style_changed_cb): Call update_theme_scrollbar_width and call
16260 x_set_scroll_bar_default_width and xg_frame_set_char_size for
16261 all frames (Bug#8505).
16262 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
16263 Call gtk_window_set_resizable if HAVE_GTK3.
16264 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
16265 and height if HAVE_GTK3 (Bug#8505).
16266 (scroll_bar_width_for_theme): New variable.
16267 (update_theme_scrollbar_width): New function.
16268 (xg_get_default_scrollbar_width): Move code to
16269 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
16270 (xg_initialize): Call update_theme_scrollbar_width.
16272 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
16274 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
16276 2011-06-12 Martin Rudalics <rudalics@gmx.at>
16278 * frame.c (make_frame): Call other_buffer_safely instead of
16281 * window.c (temp_output_buffer_show): Call display_buffer with
16282 second argument Vtemp_buffer_show_specifiers and reset latter
16283 immediately after the call.
16284 (Vtemp_buffer_show_specifiers): New variable.
16285 (auto_window_vscroll_p, next_screen_context_lines)
16286 (Vscroll_preserve_screen_position): Remove leading asterisks from

16293 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
16294 (record_buffer): Remove unused local.
16295 * frame.c (other_visible_frames, frame_buffer_list): Now static.

16307 * widgetprv.h (emacsFrameClassRec): Remove decl.
16308 * window.c (delete_deletable_window): Now returns void, since it
16309 wasn't returning anything.
16310 (compare_window_configurations): Remove unused locals.
16311 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.

16331 * window.c (delete_deletable_window): Re-add.
16332 (Fset_window_configuration): Rewrite to handle dead buffers and
16333 consequently deletable windows.
16334 (window_tree, Fwindow_tree): Remove. Supply functionality in
16336 (compare_window_configurations): Simplify code.

16354 buffer list implementation.
16355 (other_buffer_safely): New function.

16467 window_min_size_1, window_min_size_2, window_min_size,
16468 size_window, window_fixed_size_p, enlarge_window, delete_window.
16469 Remove static from declaration of Qdelete_window, it's
16470 temporarily needed by Fbury_buffer.
16471 (replace_window): Don't assign orig_top_line and
16473 (Fdelete_window, delete_window): Remove. Window deletion is

16475 (window_loop): Remove DELETE_OTHER_WINDOWS case.
16476 Replace Fdelete_window calls with calls to Qdelete_window.
16477 (Fdelete_other_windows): Remove. Deleting other windows is

16850 value of a `display' property is a "replacing spec".
16851 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
16852 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

16882 * gnutls.c: Use Emacs's memory allocators.
16883 Without this change, the gnutls library would invoke malloc etc.
16884 directly, which causes problems on non-SYNC_INPUT hosts, and which
16885 runs afoul of improving memory_full behavior. (Bug#8761)
16886 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
16887 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
16888 xfree instead of the default malloc, realloc, free.
16889 (Fgnutls_boot): No need to check for memory allocation failure,
16890 since xmalloc does that for us.

16919 need to be updated by these changes.
16920 * fns.c (make_hash_table, maybe_resize_hash_table):
16921 Check for integer overflow with large hash tables.
16922 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
16923 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
16924 (SXHASH_REDUCE): New macro.
16925 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
16926 Use it instead of discarding useful hash info with large hash values.
16927 (sxhash_float): New function.
16928 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
16929 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
16930 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
16931 Rewrite to use FIXNUM_BITS, as this simplifies things.
16932 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
16933 Adjust signatures to match updated version of code.
16934 (consing_since_gc): Now EMACS_INT, since a single hash table can
16935 use more than INT_MAX bytes.
16937 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
16939 Make it possible to build with GCC-4.6+ -O2 -flto.
16941 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
16943 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
16945 * minibuf.c (get_minibuffer, read_minibuf_unwind):
16946 Call minibuffer-inactive-mode.
16948 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
16950 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
16951 Update dependencies.
16953 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
16955 * data.c (init_data): Remove code for UTS, this system is not
16958 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
16960 Don't force ./temacs to start in terminal mode.
16962 * frame.c (make_initial_frame): Initialize faces in all cases, not
16963 only when CANNOT_DUMP is defined.
16964 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
16966 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
16968 * dispnew.c (add_window_display_history): Use const for the string
16969 pointer. Remove declaration, not needed.
16971 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
16973 Use 'inline', not 'INLINE'.
16974 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
16975 * alloc.c, fontset.c (INLINE): Remove.
16976 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
16977 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
16978 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
16979 * gmalloc.c (register_heapinfo): Use inline unconditionally.
16980 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
16982 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
16984 Make it possible to run ./temacs.
16986 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
16987 syms_of_callproc does the same thing. Remove test for
16988 "initialized", do it in the caller.
16989 * emacs.c (main): Avoid calling set_initial_environment when dumping.
16991 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
16993 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
16994 (read_minibuf): Use get_minibuffer.
16995 (syms_of_minibuf): Use DEFSYM.
16996 (Qmetadata): New var.
16997 * data.c (Qbuffer): Don't make it static.
16998 (syms_of_data): Use DEFSYM.
17000 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
17002 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
17003 (CCL_CODE_MIN): New macro.
17005 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
17007 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
17009 * eval.c (Qdebug): Now static.
17010 * lisp.h (Qdebug): Remove decl. This reverts a part of the
17011 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
17012 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
17014 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
17016 * image.c: Various fixes to ImageMagick code comments.
17017 (Fimagemagick_types): Doc fix.
17019 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
17021 Minor fixes prompted by GCC 4.6.0 warnings.
17023 * xselect.c (converted_selections, conversion_fail_tag): Now static.
17025 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
17026 (x_clipboard_manager_save_all): Move extern decl to ...
17027 * xterm.h: ... here, so that it can be checked for consistency.
17029 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
17031 * xselect.c (x_clipboard_manager_save_frame)
17032 (x_clipboard_manager_save_all): New functions.
17033 (Fx_clipboard_manager_save): Lisp function deleted.
17035 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
17036 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
17038 * xterm.h: Update prototype.
17040 2011-05-28 William Xu <william.xwl@gmail.com>
17042 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
17043 exiting (Bug#8239).
17045 2011-05-28 Jim Meyering <meyering@redhat.com>
17047 Avoid a sign-extension bug in crypto_hash_function.
17048 * fns.c (to_uchar): Define.
17049 (crypto_hash_function): Use it to convert some newly-signed
17050 variables to unsigned, to avoid sign-extension bugs. For example,
17051 without this change, (md5 "truc") would evaluate to
17052 45723a2aff78ff4fff7fff1114760e62 rather than the expected
17053 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
17054 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
17056 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17058 Integer overflow fixes.
17060 * dbusbind.c: Serial number integer overflow fixes.
17061 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
17062 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
17063 to hold a serial number that is too large for a fixnum.
17064 (Fdbus_method_return_internal, Fdbus_method_error_internal):
17065 Check for serial numbers out of range. Decode any serial number
17066 that was so large that it became a float. (Bug#8722)
17068 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
17069 (Fdbus_call_method, Fdbus_call_method_asynchronously):
17070 Use XFASTINT rather than XUINT when numbers are nonnegative.
17071 (xd_append_arg, Fdbus_method_return_internal):
17072 (Fdbus_method_error_internal): Likewise. Also, for unsigned
17073 arguments, check that Lisp number is nonnegative, rather than
17074 silently wrapping negative numbers around. (Bug#8722)
17075 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
17078 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
17080 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
17082 ccl: Add integer overflow checks.
17083 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
17084 (IN_INT_RANGE): New macros.
17085 (ccl_driver): Use them to check for integer overflow when
17086 decoding a CCL program. Many of the new checks are whether XINT (x)
17087 fits in int; it doesn't always, on 64-bit hosts. The new version
17088 doesn't catch all possible integer overflows, but it's an
17089 improvement. (Bug#8719)
17091 * alloc.c (make_event_array): Use XINT, not XUINT.
17092 There's no need for unsigned here.
17094 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
17095 This follows up to the 2011-05-06 change that substituted uintptr_t
17096 for EMACS_INT. This case wasn't caught back then.
17098 Rework Fformat to avoid integer overflow issues.
17099 * editfns.c: Include <float.h> unconditionally, as it's everywhere
17100 now (part of C89). Include <verify.h>.
17101 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
17102 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
17103 (Fformat): Avoid the prepass trying to compute sizes; it was only
17104 approximate and thus did not catch overflow reliably. Instead, walk
17105 through the format just once, formatting and computing sizes as we go,
17106 checking for integer overflow at every step, and allocating a larger
17107 buffer as needed. Keep track separately whether the format is
17108 multibyte. Keep only the most-recently calculated precision, rather
17109 than them all. Record whether each argument has been converted to
17110 string. Use EMACS_INT, not int, for byte and char and arg counts.
17111 Support field widths and precisions larger than INT_MAX. Avoid
17112 sprintf's undefined behavior with conversion specifications such as %#d
17113 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
17114 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
17115 formatting out-of-range floating point numbers with int
17116 formats. (Bug#8668)
17118 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
17120 * data.c: Avoid integer truncation in expressions involving floats.
17121 * data.c: Include <intprops.h>.
17122 (arith_driver): When there's an integer overflow in an expression
17123 involving floating point, convert the integers to floating point
17124 so that the resulting value does not suffer from catastrophic
17125 integer truncation. For example, on a 64-bit host (* 4
17126 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
17127 Do not rely on undefined behavior after integer overflow.
17129 merge count_size_as_multibyte, parse_str_to_multibyte
17130 * character.c, character.h (count_size_as_multibyte):
17131 Rename from parse_str_to_multibyte; all uses changed.
17132 Check for integer overflow.
17133 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
17134 since it's now a duplicate of the other. This is more of
17135 a character than a buffer op, so better that it's in character.c.
17136 * fns.c, print.c: Adjust to above changes.
17138 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
17140 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
17142 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17144 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17145 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
17146 (x_clipboard_manager_save): Now static.
17147 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
17149 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17150 (crypto_hash_function): Now static.
17151 Fix pointer signedness problems. Avoid unnecessary initializations.
17153 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
17155 * termhooks.h (Vselection_alist): Make it terminal-local.
17157 * terminal.c (create_terminal): Initialize it.
17159 * xselect.c: Support for clipboard managers.
17160 (Vselection_alist): Move to termhooks.h as terminal-local var.
17161 (LOCAL_SELECTION): New macro.
17162 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
17163 (symbol_to_x_atom): Remove gratuitous arg.
17164 (x_handle_selection_request, lisp_data_to_selection_data)
17165 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
17166 (x_own_selection, x_get_local_selection, x_convert_selection):
17167 New arg, specifying work frame. Use terminal-local Vselection_alist.
17168 (some_frame_on_display): Delete unused function.
17169 (Fx_own_selection_internal, Fx_get_selection_internal)
17170 (Fx_disown_selection_internal, Fx_selection_owner_p)
17171 (Fx_selection_exists_p): New optional frame arg.
17172 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
17173 (x_handle_selection_clear): Don't treat other terminals with the
17174 same keyboard specially. Use the terminal-local Vselection_alist.
17175 (x_clear_frame_selections): Use Frun_hook_with_args.
17177 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
17179 * xterm.h: Add support for those atoms.
17181 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
17183 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
17184 (converted_selections, conversion_fail_tag): New global variables.
17185 (x_selection_request_lisp_error): Free the above.
17186 (x_get_local_selection): Remove unnecessary code.
17187 (x_reply_selection_request): Args changed; handle arbitrary array
17188 of converted selections stored in converted_selections.
17189 Separate the XChangeProperty and SelectionNotify steps.
17190 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
17191 (x_convert_selection): New function.
17192 (x_handle_selection_event): Simplify.
17193 (x_get_foreign_selection): Don't ignore incoming requests while
17194 waiting for an answer; this will fail when we implement
17195 SAVE_TARGETS, and seems unnecessary anyway.
17196 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
17197 (Vx_sent_selection_functions): Doc fix.
17199 2011-05-26 Leo Liu <sdl.web@gmail.com>
17201 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
17203 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17205 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
17207 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
17208 for fringe update if it has periodic bitmap.
17209 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
17210 and fringe_bitmap_periodic_p.
17212 * fringe.c (get_fringe_bitmap_data): New function.
17213 (draw_fringe_bitmap_1, update_window_fringes): Use it.
17214 (update_window_fringes): Record periodicity of fringe bitmap in glyph
17215 row. Mark glyph row for fringe update if periodicity changed.
17217 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
17218 for fringe update unless it has periodic bitmap.
17220 2011-05-25 Kenichi Handa <handa@m17n.org>
17222 * xdisp.c (get_next_display_element): Set correct it->face_id for
17223 a static composition.
17225 2011-05-24 Leo Liu <sdl.web@gmail.com>
17228 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
17230 * fns.c (crypto_hash_function, Fsha1): New function.
17231 (Fmd5): Use crypto_hash_function.
17232 (syms_of_fns): Add Ssha1.
17234 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
17236 * gnutls.c: Remove unused macros.
17237 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
17238 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
17239 Remove macros that are defined and never used.
17240 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
17242 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17244 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
17245 (Fx_get_selection_internal): Minor cleanup.
17246 (Fx_own_selection_internal): Rename arguments for consistency with
17249 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
17251 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
17253 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17255 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
17257 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17259 * dispnew.c (scrolling_window): Don't exclude the case that the
17260 last enabled row in the desired matrix touches the bottom boundary.
17262 2011-05-21 Glenn Morris <rgm@gnu.org>
17264 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
17265 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
17266 and add some more files.
17268 2011-05-20 Eli Zaretskii <eliz@gnu.org>
17270 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
17271 report_file_error introduced by the change from 2011-05-07.
17273 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
17275 * systime.h (Time): Define only if emacs is defined.
17276 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
17277 where the include path doesn't have X11/X.h by default. See
17278 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
17280 2011-05-20 Kenichi Handa <handa@m17n.org>
17282 * composite.c (find_automatic_composition): Fix previous change.
17284 2011-05-20 Glenn Morris <rgm@gnu.org>
17286 * lisp.mk: New file, split from Makefile.in.
17287 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
17288 (shortlisp): Remove.
17289 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
17291 2011-05-19 Glenn Morris <rgm@gnu.org>
17293 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
17294 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
17295 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
17296 (lisp): Set the order to that of loadup.el.
17297 (shortlisp): Make it a copy of $lisp.
17298 (SOME_MACHINE_LISP): Remove.
17299 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
17300 Use just $shortlisp, not $SOME_MACHINE_LISP too.
17302 2011-05-18 Kenichi Handa <handa@m17n.org>
17304 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
17305 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
17306 (find_automatic_composition): Mostly rewrite for efficiency.
17308 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
17310 * makefile.w32-in: Update dependencies.
17312 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
17314 * menu.c: Include limits.h (fixes the MS-Windows build broken by
17315 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
17317 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
17319 Fix some integer overflow issues, such as string length overflow.
17321 * insdel.c (count_size_as_multibyte): Check for string overflow.
17323 * character.c (lisp_string_width): Check for string overflow.
17324 Use EMACS_INT, not int, for string indexes and lengths; in
17325 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
17326 the resulting string length overflows an EMACS_INT; instead,
17327 report a string overflow if no precision given. When checking for
17328 precision exhaustion, use a check that cannot possibly have
17329 integer overflow. (Bug#8675)
17330 * character.h (lisp_string_width): Adjust to new signature.
17332 * alloc.c (string_overflow): New function.
17333 (Fmake_string): Use it. This doesn't change behavior, but saves
17334 a few bytes and will simplify future changes.
17335 * character.c (string_escape_byte8): Likewise.
17336 * lisp.h (string_overflow): New decl.
17338 Fixups, following up to the user-interface timestamp change.
17339 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
17340 for UI timestamps, instead of unsigned long.
17341 * msdos.c (mouse_get_pos): Likewise.
17342 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
17343 * w32gui.h (Time): Define by including "systime.h" rather than by
17344 declaring it ourselves. (Bug#8664)
17346 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
17347 * image.c (clear_image_cache): Likewise.
17349 * term.c (term_mouse_position): Don't assume time_t wraparound.
17351 Be more systematic about user-interface timestamps.
17352 Before, the code sometimes used 'Time', sometimes 'unsigned long',
17353 and sometimes 'EMACS_UINT', to represent these timestamps.
17354 This change causes it to use 'Time' uniformly, as that's what X uses.
17355 This makes the code easier to follow, and makes it easier to catch
17356 integer overflow bugs such as Bug#8664.
17357 * frame.c (Fmouse_position, Fmouse_pixel_position):
17358 Use Time, not unsigned long, for user-interface timestamps.
17359 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
17360 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
17361 * keyboard.h (last_event_timestamp): Likewise.
17362 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
17363 * menu.h (xmenu_show): Likewise.
17364 * term.c (term_mouse_position): Likewise.
17365 * termhooks.h (struct input_event.timestamp): Likewise.
17366 (struct terminal.mouse_position_hook): Likewise.
17367 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
17368 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
17369 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
17370 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
17371 what it was before.
17372 * menu.h, termhooks.h: Include "systime.h", for Time.
17374 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
17375 Don't assume that the difference between two unsigned long values
17376 can fit into an integer. At this point, we know button_down_time
17377 <= event->timestamp, so the difference must be nonnegative, so
17378 there's no need to cast the result if double-click-time is
17379 nonnegative, as it should be; check that it's nonnegative, just in
17380 case. This bug is triggered when events are more than 2**31 ms
17381 apart (about 25 days). (Bug#8664)
17383 * xselect.c (last_event_timestamp): Remove duplicate decl.
17384 (x_own_selection): Remove needless cast to unsigned long.
17386 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
17387 that always fit in int. Use a sentinel instead of a counter, to
17388 avoid a temp and to allay GCC's concerns about possible int overflow.
17389 * frame.h (struct frame): Use int for menu_bar_items_used
17390 instead of EMACS_INT, since it always fits in int.
17392 * menu.c (grow_menu_items): Check for int overflow.
17394 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
17396 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
17397 Before, the code was not consistent. These values cannot exceed
17398 2**31 - 1 so there's no need to make them unsigned.
17399 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
17400 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
17401 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
17403 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
17405 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
17406 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
17407 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
17408 presumably because the widths might not match.
17410 * window.c (size_window): Avoid needless test at loop start.
17412 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
17414 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
17416 2011-05-12 Drew Adams <drew.adams@oracle.com>
17418 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
17420 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17422 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
17423 `width' to `bar_area_x' and `bar_area_width', respectively.
17424 (x_scroll_run): Take account of fringe background extension.
17426 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
17427 Rename local vars `left' and `width' to `bar_area_x' and
17428 `bar_area_width', respectively.
17429 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
17430 background extension.
17432 2011-05-10 Jim Meyering <meyering@redhat.com>
17434 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
17436 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
17438 * image.c (Finit_image_library): Return t for built-in image types,
17439 like pbm and xbm. (Bug#8640)
17441 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
17443 * w32menu.c (set_frame_menubar): Fix submenu allocation.
17445 2011-05-07 Eli Zaretskii <eliz@gnu.org>
17447 * w32console.c (Fset_screen_color): Doc fix.
17448 (Fget_screen_color): New function.
17449 (syms_of_ntterm): Defsubr it.
17451 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
17452 unlink the temporary file if Fcall_process didn't create it in the
17454 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
17455 child process will be redirected to a file specified with `:file'.
17456 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
17457 cue to call_process_cleanup not to close that handle.
17459 2011-05-07 Ben Key <bkey76@gmail.com>
17461 * makefile.w32-in: The bootstrap-temacs rule now makes use of
17462 one of two shell specific rules, either bootstrap-temacs-CMD or
17463 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
17464 to the previous implementation of the bootstrap-temacs rule.
17465 The bootstrap-temacs-CMD rule is similar to the previous
17466 implementation of the bootstrap-temacs rule except that it
17467 makes use of the ESC_CFLAGS variable instead of the CFLAGS
17470 These changes, along with some changes to nt/configure.bat,
17471 nt/gmake.defs, and nt/nmake.defs, are required to extend my
17472 earlier fix to add support for --cflags and --ldflags options
17473 that include quotes so that it works whether make uses cmd or
17476 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
17478 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
17479 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
17481 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
17482 a string. Handle both cases.
17483 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
17484 (Fdbus_register_method): Use Qinvalid_function.
17486 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
17488 * makefile.w32-in: Update dependencies.
17489 (LISP_H): Add inttypes.h and stdin.h.
17490 (PROCESS_H): Add unistd.h.
17492 2011-05-06 Eli Zaretskii <eliz@gnu.org>
17494 * lread.c: Include limits.h (fixes the MS-Windows build broken by
17495 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
17497 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
17499 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
17501 * term.c (vfatal): Remove stray call to va_end.
17502 It's not needed and the C Standard doesn't allow it here anyway.
17504 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
17505 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
17507 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
17510 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
17512 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
17514 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
17516 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
17518 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
17520 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
17521 * charset.c (Fdefine_charset_internal): Don't initialize
17522 charset.code_space[15]. The value was garbage, on hosts with
17523 32-bit int (Bug#8600).
17525 * lread.c (read_integer): Be more consistent with string-to-number.
17526 Use string_to_number to do the actual conversion; this avoids
17527 rounding errors and fixes some other screwups. Without this fix,
17528 for example, #x1fffffffffffffff was misread as -2305843009213693952.
17529 (digit_to_number): Move earlier, for benefit of read_integer.
17530 Return -1 if the digit is out of range for the base, -2 if it is
17531 not a digit in any supported base. (Bug#8602)
17533 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
17535 * dispnew.c (scrolling_window): Return 1 if we scrolled,
17536 to match comment at start of function. This also removes a
17537 GCC warning about overflow in a 32+64-bit port.
17539 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
17541 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
17542 Reported by Stefan Monnier in
17543 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
17544 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
17545 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
17547 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
17548 (EMACS_UINTPTR): Likewise, with uintptr_t.
17550 * lisp.h: Prefer 64-bit EMACS_INT if available.
17551 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
17552 on 32-bit hosts that have 64-bit int, so that they can access
17554 However, temporarily disable this change unless the temporary
17555 symbol WIDE_EMACS_INT is defined.
17557 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
17559 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
17560 This removes an assumption that EMACS_INT and long are the same
17561 width as pointers. The assumption is true for Emacs porting targets
17562 now, but we want to make other targets possible.
17563 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
17564 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
17565 In the rest of the code, change types of integers that hold casted
17566 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
17567 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
17568 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
17569 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
17570 No need to cast type when ORing.
17571 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
17572 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
17573 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
17574 assume EMACS_INT is the same width as char *.
17575 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
17576 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
17577 Remove no-longer-needed casts.
17578 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
17579 (xg_tool_bar_help_callback, xg_make_tool_item):
17580 Use EMACS_INTPTR to hold an integer
17581 that will be cast to void *; this can avoid a GCC warning
17582 if EMACS_INT is not the same width as void *.
17583 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
17584 * xdisp.c (display_echo_area_1, resize_mini_window_1):
17585 (current_message_1, set_message_1):
17586 Use a local to convert to proper width without a cast.
17587 * xmenu.c (dialog_selection_callback): Likewise.
17589 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
17590 Also, don't assume VALBITS / RAND_BITS is less than 5,
17591 and don't rely on undefined behavior when shifting a 1 left into
17593 * lisp.h (get_random): Change signature to match.
17595 * lread.c (hash_string): Use size_t, not int, for hash computation.
17596 Normally we prefer signed values; but hashing is special, because
17597 it's better to use unsigned division on hash table sizes so that
17598 the remainder is nonnegative. Also, size_t is the natural width
17599 for hashing into memory. The previous code used 'int', which doesn't
17600 retain enough info to hash well into very large tables.
17601 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
17603 * dbusbind.c: Don't possibly lose pointer info when converting.
17604 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
17605 Use XPNTR rather than XHASH, so that the high-order bits of
17606 the pointer aren't lost when converting through void *.
17608 * eval.c (Fautoload): Don't double-shift a pointer.
17610 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
17612 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
17614 * gnutls.c (DEF_GNUTLS_FN):
17615 * image.c (DEF_IMGLIB_FN): Make function pointers static.
17617 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
17619 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
17622 2011-05-05 Eli Zaretskii <eliz@gnu.org>
17624 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
17625 New version that can reserve upto 2GB of heap space.
17627 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
17629 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
17631 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
17633 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
17634 `gnutls_certificate_set_x509_key_file'.
17636 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
17638 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
17639 Update dependencies.
17641 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
17643 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
17644 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
17645 Remove unused parameter `fildes'.
17646 * process.c (read_process_output, send_process): Don't pass it.
17648 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
17650 Fix previous change: the library cache is defined in w32.c.
17651 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
17652 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
17654 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
17656 Implement dynamic loading of GnuTLS on Windows.
17658 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
17659 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
17660 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
17663 * gnutls.c (Qgnutls_dll): Define.
17664 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
17665 (gnutls_*): Declare function pointers.
17666 (init_gnutls_functions): New function to initialize function pointers.
17667 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
17668 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
17669 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
17670 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
17671 (emacs_gnutls_write, emacs_gnutls_read)
17672 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
17673 (Fgnutls_available_p): New function.
17674 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
17675 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
17676 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
17678 * image.c: Include w32.h.
17679 (Vimage_type_cache): Delete.
17680 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
17681 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
17682 (w32_delayed_load): Move to w32.c.
17684 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
17686 * w32.c (QCloaded_from, Vlibrary_cache): Define.
17687 (w32_delayed_load): Move from image.c. When loading a library, record
17688 its filename in the :loaded-from property of the library id.
17689 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
17690 Initialize and staticpro them.
17691 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
17693 * process.c: Include lisp.h before w32.h, not after.
17694 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
17695 instead of gnutls_record_check_pending.
17697 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
17699 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
17701 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
17702 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
17705 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
17707 * xterm.c (x_set_frame_alpha): Do not set property on anything
17708 else than FRAME_X_OUTER_WINDOW (Bug#8608).
17710 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
17712 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
17714 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
17716 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
17717 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)
17718 (Qgnutls_e_invalid_session, Qgnutls_e_not_ready_for_handshake)

17723 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
17724 (Qgnutls_bootprop_callbacks_verify): Make static.
17726 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
17728 * callproc.c: Indentation fixup.
17730 * sysdep.c (wait_for_termination_1): Make static.
17731 (wait_for_termination, interruptible_wait_for_termination):
17732 Move after wait_for_termination_1.
17734 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
17736 * sysdep.c (interruptible_wait_for_termination): New function
17737 which is like wait_for_termination, but allows keyboard
17740 * callproc.c (Fcall_process): Add (:file "file") as an option for
17742 (Fcall_process_region): Ditto.
17744 2011-04-30 Eli Zaretskii <eliz@gnu.org>
17746 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
17747 rather than `XVECTOR (FOO)->size'.
17749 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
17750 inttypes.h, as a gnulib replacement is used if it not available in
17753 2011-04-21 Eli Zaretskii <eliz@gnu.org>
17755 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
17756 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
17757 of MOST_POSITIVE_FIXNUM. (Bug#8528)
17759 * coding.c (coding_alloc_by_realloc): Error out if destination
17760 will grow beyond MOST_POSITIVE_FIXNUM.
17761 (decode_coding_emacs_mule): Abort if there isn't enough place in
17762 charbuf for the composition carryover bytes. Reserve an extra
17763 space for up to 2 characters produced in a loop.
17764 (decode_coding_iso_2022): Abort if there isn't enough place in
17765 charbuf for the composition carryover bytes.
17767 2011-04-21 Eli Zaretskii <eliz@gnu.org>
17769 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
17770 aborting when %lld or %lll format is passed.
17771 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
17772 %llo or %llx format is passed. (Bug#8545)
17774 * window.c (window_scroll_line_based): Use a marker instead of
17775 simple variables to record original value of point. (Bug#7952)
17777 * doprnt.c (doprnt): Fix the case where a multibyte sequence
17778 produced by %s or %c overflows available buffer space. (Bug#8545)
17780 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
17782 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
17783 (SIZE_MAX): Move defn after all includes, as they might #define it.
17785 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
17787 * w32.c (init_environment): Warn about defaulting HOME to C:\.
17789 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
17791 * keyboard.c (Qdelayed_warnings_hook): Define.
17792 (command_loop_1): Run `delayed-warnings-hook'
17793 if Vdelayed_warnings_list is non-nil.
17794 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
17795 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
17797 2011-04-28 Eli Zaretskii <eliz@gnu.org>
17799 * doprnt.c (doprnt): Don't return value smaller than the buffer
17800 size if the message was truncated. (Bug#8545).
17802 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
17804 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
17805 (Fx_window_property): #if-0 the whole functions, not just the bodies.
17807 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
17809 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
17811 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
17813 * makefile.w32-in: Update dependencies.
17815 2011-04-27 Eli Zaretskii <eliz@gnu.org>
17817 Improve `doprnt' and its usage. (Bug#8545)
17818 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
17819 `format_end'. Remove support for %l as a conversion specifier.
17820 Don't use xrealloc. Improve diagnostics when the %l size modifier
17821 is used. Update the commentary.
17823 * eval.c (verror): Simplify calculation of size_t.
17825 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
17828 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
17830 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
17833 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
17835 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
17836 This makes this file independent of the recent pseudovector change.
17838 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
17840 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
17842 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
17843 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
17844 Remove unused local.
17845 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
17847 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
17848 GCC 4.6.0 optimizes based on type-based alias analysis.
17849 For example, if b is of type struct buffer * and v of type struct
17850 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
17851 != &v->size, and therefore "v->size = 1; b->size = 2; return
17852 v->size;" must therefore return 1. This assumption is incorrect
17853 for Emacs, since it type-puns struct Lisp_Vector * with many other
17854 types. To fix this problem, this patch adds a new type struct
17855 vectorlike_header that documents the constraints on layout of vectors
17856 and pseudovectors, and helps optimizing compilers not get fooled
17857 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
17858 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
17859 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
17861 (XSETPVECTYPE): Rewrite in terms of new macro.
17862 (XSETPVECTYPESIZE): New macro, specifying both type and size.
17863 This is a bit clearer, and further avoids the possibility of
17864 undesirable aliasing.
17865 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
17866 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
17867 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
17868 since Lisp_Subr is a special case (no "next" field).
17869 (ASIZE): Now uses header.size rather than size.
17870 All previous uses of XVECTOR (foo)->size replaced to use this macro,
17871 to avoid the hassle of writing XVECTOR (foo)->header.size.
17872 (struct vectorlike_header): New type.
17873 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
17874 object, to help avoid aliasing.
17875 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
17876 (SUBRP): Likewise, since Lisp_Subr is a special case.
17877 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
17878 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
17879 (struct Lisp_Hash_Table): Combine first two members into a single
17880 struct vectorlike_header member. All uses of "size" and "next" members
17881 changed to be "header.size" and "header.next".
17882 * buffer.h (struct buffer): Likewise.
17883 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
17884 * frame.h (struct frame): Likewise.
17885 * process.h (struct Lisp_Process): Likewise.
17886 * termhooks.h (struct terminal): Likewise.
17887 * window.c (struct save_window_data, struct saved_window): Likewise.
17888 * window.h (struct window): Likewise.
17889 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
17890 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
17891 * buffer.c (init_buffer_once): Likewise.
17892 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
17894 * process.c (Fformat_network_address): Use local var for size,
17897 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
17899 Make the Lisp reader and string-to-float more consistent (Bug#8525)
17900 * data.c (atof): Remove decl; no longer used or needed.
17901 (digit_to_number): Move to lread.c.
17902 (Fstring_to_number): Use new string_to_number function, to be
17903 consistent with how the Lisp reader treats infinities and NaNs.
17904 Do not assume that floating-point numbers represent EMACS_INT
17905 without losing information; this is not true on most 64-bit hosts.
17906 Avoid double-rounding errors, by insisting on integers when
17907 parsing non-base-10 numbers, as the documentation specifies.
17908 * lisp.h (string_to_number): New decl, replacing ...
17909 (isfloat_string): Remove.
17910 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
17911 (read1): Do not accept +. and -. as integers; this
17912 appears to have been a coding error. Similarly, do not accept
17913 strings like +-1e0 as floating point numbers. Do not report
17914 overflow for integer overflows unless the base is not 10 which
17915 means we have no simple and reliable way to continue.
17916 Break out the floating-point parsing into a new
17917 function string_to_number, so that Fstring_to_number parses
17918 floating point numbers consistently with the Lisp reader.
17919 (digit_to_number): Move here from data.c. Make it static inline.
17920 (E_CHAR, EXP_INT): Remove, replacing with ...
17921 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
17922 (string_to_number): New function, replacing isfloat_string.
17923 This function checks for valid syntax and produces the resulting
17924 Lisp float number too. Rework it so that string-to-number
17925 no longer mishandles examples like "1.0e+". Use strtoumax,
17926 so that overflow for non-base-10 numbers is reported only when
17927 there's no portable and simple way to convert to floating point.
17929 * textprop.c (set_text_properties_1): Rewrite for clarity,
17930 and to avoid GCC warning about integer overflow.
17932 * intervals.h (struct interval): Use EMACS_INT for members
17933 where EMACS_UINT might cause problems. See
17934 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
17935 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
17936 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
17938 (offset_intervals): Tell GCC not to worry about length overflow
17939 when negating a negative length.
17941 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
17942 (overrun_check_free): Likewise.
17944 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
17945 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
17948 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
17949 (gnutls_make_error): Rename local to avoid shadowing.
17950 (gnutls_emacs_global_deinit): ifdef out; not used.
17951 (Fgnutls_boot): Use const for pointer to readonly storage.
17952 Comment out unused local. Fix pointer signedness problems.
17954 * lread.c (openp): Don't stuff size_t into an 'int'.
17955 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
17956 about possible signed overflow.
17958 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
17959 (GDK_KEY_g): Don't define if already defined.
17960 (xg_prepare_tooltip): Avoid pointer signedness problem.
17961 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
17963 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
17964 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
17966 * xfns.c (Fx_window_property): Simplify a bit,
17967 to make a bit faster and to avoid GCC 4.6.0 warning.
17968 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
17970 * fns.c (internal_equal): Don't assume size_t fits in int.
17972 * alloc.c (compact_small_strings): Tighten assertion a little.
17974 Replace pEd with more-general pI, and fix some printf arg casts.
17975 * lisp.h (pI): New macro, generalizing old pEd macro to other
17976 conversion specifiers. For example, use "...%"pI"d..." rather
17977 than "...%"pEd"...".
17978 (pEd): Remove. All uses replaced with similar uses of pI.
17979 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
17980 * alloc.c (check_pure_size): Don't overflow by converting size to int.
17981 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
17982 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
17983 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
17984 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
17985 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
17987 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
17988 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
17989 * print.c (safe_debug_print, print_object): Likewise.
17990 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
17992 Use pI instead of if-then-else-abort. Use %p to avoid casts,
17993 avoiding the 0 flag, which is not portable.
17994 * process.c (Fmake_network_process): Use pI to avoid cast.
17995 * region-cache.c (pp_cache): Likewise.
17996 * xdisp.c (decode_mode_spec): Likewise.
17997 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
17998 behavior on 64-bit hosts with printf arg.
17999 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
18000 (x_stop_queuing_selection_requests): Likewise.
18001 (x_get_window_property): Don't truncate byte count to an 'int'
18004 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
18005 here, since it parses constructs like leading '-' and spaces,
18006 which are not wanted; and it overflows with large numbers.
18007 Instead, simply match F[0-9]+, which is what is wanted anyway.
18009 * alloc.c: Remove unportable assumptions about struct layout.
18010 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
18011 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
18012 (allocate_vectorlike, make_pure_vector): Use the new macros,
18013 plus offsetof, to remove unportable assumptions about struct layout.
18014 These assumptions hold on all porting targets that I know of, but
18015 they are not guaranteed, they're easy to remove, and removing them
18016 makes further changes easier.
18018 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
18019 This doesn't fix a bug but makes the code clearer.
18020 (string_overrun_cookie): Now const. Use initializers that
18021 don't formally overflow signed char, to avoid warnings.
18022 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
18023 can cause Emacs to crash when string overrun checking is enabled.
18024 (allocate_buffer): Don't assume sizeof (struct buffer) is a
18025 multiple of sizeof (EMACS_INT); it need not be, if
18026 alignof(EMACS_INT) < sizeof (EMACS_INT).
18027 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
18029 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

18036 supposed to be handshaking. (Bug#8556)
18037 Reported by Paul Eggert <eggert@cs.ucla.edu>.
18039 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

18044 (handle_user_signal): Break into debugger when debug-on-event
18045 matches the current signal symbol.
18047 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
18049 * alloc.c (check_sblock, check_string_bytes)
18050 (check_string_free_list): Convert to standard C.
18052 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
18054 * w32.c (emacs_gnutls_push): Fix typo.
18056 2011-04-25 Eli Zaretskii <eliz@gnu.org>
18058 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
18059 "cast to pointer from integer of different size".
18061 Improve doprnt and its use in verror. (Bug#8545)
18062 * doprnt.c (doprnt): Document the set of format control sequences
18063 supported by the function. Use SAFE_ALLOCA instead of always
18066 * eval.c (verror): Don't limit the buffer size at size_max-1, that
18067 is one byte too soon. Don't use xrealloc; instead xfree and
18070 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
18072 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
18075 * gnutls.c: Renamed global_initialized to
18076 gnutls_global_initialized. Added internals for the
18077 :verify-hostname-error, :verify-error, and :verify-flags
18078 parameters of `gnutls-boot' and documented those parameters in the
18079 docstring. Start callback support.
18080 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
18081 unless a fatal error occurred. Call gnutls_alert_send_appropriate
18082 on error. Return error code.
18083 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
18084 (emacs_gnutls_read): Likewise.
18085 (Fgnutls_boot): Return handshake error code.

18149 <char-direction-table>: Deleted.
18151 2011-04-23 Eli Zaretskii <eliz@gnu.org>
18153 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
18154 * doprnt.c: Include limits.h.
18155 (SIZE_MAX): New macro.
18156 (doprnt): Return a size_t value. 2nd arg is now size_t.
18157 Many local variables are now size_t instead of int or unsigned.
18158 Improve overflow protection. Support `l' modifier for integer
18159 conversions. Support %l conversion. Don't assume an EMACS_INT
18160 argument for integer conversions and for %c.
18162 * lisp.h (doprnt): Restore prototype.
18164 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
18165 $(SRC)/character.h.
18167 * Makefile.in (base_obj): Add back doprnt.o.
18169 * deps.mk (doprnt.o): Add back prerequisites.
18170 (callint.o): Depend on character.h.
18172 * eval.c (internal_lisp_condition_case): Include the handler
18173 representation in the error message.
18174 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
18175 when breaking from the loop.
18177 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
18179 * callint.c (Fcall_interactively): When displaying error message
18180 about invalid control letter, pass the character's codepoint, not
18181 a pointer to its multibyte form. Improve display of the character
18182 in octal and display also its hex code.
18184 * character.c (char_string): Use %x to display the (unsigned)
18185 codepoint of an invalid character, to avoid displaying a bogus
18188 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
18189 `error', not SYMBOL_NAME itself.
18191 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
18192 character arguments to `error'.
18194 * charset.c (check_iso_charset_parameter): Fix incorrect argument
18195 to `error' in error message about FINAL_CHAR argument. Make sure
18196 FINAL_CHAR is a character, and use %c when it is passed as
18197 argument to `error'.

18387 ns_descriptor_to_entity that were caused by using free to
18388 deallocate memory blocks that were allocated by xmalloc (via
18389 xstrdup). This caused Emacs to crash when compiled with
18390 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with

18409 (emacs_read, emacs_write): Use it.
18410 * process.c (send_process): Adjust to the new signatures of
18411 emacs_write and emacs_gnutls_write. Do not attempt to store

18741 * lisp.h: Remove these decls.
18743 * buffer.c (buffer_count): Remove unused var.
18745 * bidi.c (bidi_dump_cached_states): Mark as externally visible,

18747 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
18748 * dispextern.h (bidi_dump_cached_states): Remove, since it's
18749 exported only to the debugger.
18751 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
18752 * atimer.h (run_all_atimers): Remove; not exported.
18754 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
18755 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
18756 was inaccessible from Lisp.
18757 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
18758 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
18760 alloc.c: Import and export fewer symbols, and remove unused items.
18761 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
18763 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
18764 it's not optimized away by whole-program optimization.
18765 (message_enable_multibyte, free_misc): Remove.
18766 (catchlist, handlerlist, mark_backtrace):
18767 Declare only if BYTE_MARK_STACK.

18776 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
18777 (mark_backtrace): Define only if BYTE_MARK_STACK.
18778 * xdisp.c (message_enable_multibyte): Now static.
18780 Declare Lisp_Object Q* variables to be 'static' if not exported.
18781 This makes it easier for human readers (and static analyzers)
18782 to see whether these variables are used from other modules.
18783 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
18784 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:

18793 Remove decls of unexported vars.
18794 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
18796 * lisp.h (DEFINE_FUNC): Make sname 'static'.
18798 Make Emacs functions such as Fatom 'static' by default.
18799 This makes it easier for human readers (and static analyzers)
18800 to see whether these functions can be called from other modules.
18801 DEFUN now defines a static function. To make the function external
18802 so that it can be used in other C modules, use the new macro DEFUE.
18803 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
18804 (Finit_image_library):
18805 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):

18807 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
18808 Remove decls, since these functions are now static.
18809 (Funintern, Fget_internal_run_time): New decls, since these functions
18810 were already external.
18812 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

18820 Mark functions with DEFUE instead of DEFUN,
18821 if they are used in other modules.
18822 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
18823 decls for now-static functions.
18824 * buffer.h (Fdelete_overlay): Remove decl.

18860 2011-04-13 Eli Zaretskii <eliz@gnu.org>
18862 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
18863 when at ZV. (Bug#8487)
18865 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
18867 * charset.c (Fclear_charset_maps): Use xfree instead of free.

18873 * xsettings.c (read_and_apply_settings): Likewise.
18875 * alloc.c (overrun_check_malloc, overrun_check_realloc)
18876 (overrun_check_free): Protoize.
18878 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
18880 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
18881 since callers should never pass a negative size.
18882 Change the signature to match that of plain 'read' and 'write'; see
18883 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
18884 * lisp.h: Update prototypes of emacs_write and emacs_read.
18886 2011-04-11 Eli Zaretskii <eliz@gnu.org>
18888 * xdisp.c (redisplay_window): Don't try to determine the character
18889 position of the scroll margin if the window start point w->startp
18890 is outside the buffer's accessible region. (Bug#8468)
18892 2011-04-10 Eli Zaretskii <eliz@gnu.org>
18894 Fix write-region and its subroutines for buffers > 2GB.
18895 * fileio.c (a_write, e_write): Modify declaration of arguments and
18896 local variables to support buffers larger than 2GB.
18897 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
18899 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
18900 argument, local variables, and return value.
18902 * lisp.h: Update prototypes of emacs_write and emacs_read.
18904 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
18906 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
18908 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
18910 Fix more problems found by GCC 4.6.0's static checks.
18912 * xdisp.c (vmessage): Use a better test for character truncation.
18914 * charset.c (load_charset_map): <, not <=, for optimization,
18915 and to avoid potential problems with integer overflow.
18916 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
18917 * casetab.c (set_identity, shuffle): Likewise.
18918 * editfns.c (Fformat): Likewise.
18919 * syntax.c (skip_chars): Likewise.
18921 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
18922 This also lets GCC 4.6.0 generate slightly better loop code.
18924 * callint.c (Fcall_interactively): <, not <=, for optimization.
18925 (Fcall_interactively): Count the number of arguments produced,
18926 not the number of arguments given. This is simpler and lets GCC
18927 4.6.0 generate slightly better code.
18929 * ftfont.c: Distingish more carefully between FcChar8 and char.
18930 The previous code passed unsigned char * to a functions like
18931 strlen and xstrcasecmp that expect char *, which does not
18932 conform to the C standard.
18933 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
18934 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
18935 char * when the C standard requires it.
18937 * keyboard.c (read_char): Remove unused var.
18939 * eval.c: Port to Windows vsnprintf (Bug#8435).
18940 Include <limits.h>.
18941 (SIZE_MAX): Define if the headers do not.
18942 (verror): Do not give up if vsnprintf returns a negative count.
18943 Instead, grow the buffer. This ports to Windows vsnprintf, which
18944 does not conform to C99. Problem reported by Eli Zaretskii.
18945 Also, simplify the allocation scheme, by avoiding the need for
18946 calling realloc, and removing the ALLOCATED variable.
18948 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
18950 Remove invocations of doprnt, as Emacs now uses vsnprintf.
18951 But keep the doprint source code for now, as we might revamp it
18952 and use it again (Bug#8435).
18953 * lisp.h (doprnt): Remove.
18954 * Makefile.in (base_obj): Remove doprnt.o.
18955 * deps.mk (doprnt.o): Remove.
18957 error: Print 32- and 64-bit integers portably (Bug#8435).
18958 Without this change, on typical 64-bit hosts error ("...%d...", N)
18959 was used to print both 32- and 64-bit integers N, which relied on
18960 undefined behavior.
18961 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
18962 * lisp.h (error, verror): Mark as printf-like functions.
18963 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
18964 Report overflow in size calculations when allocating printf buffer.
18965 Do not truncate output string at its first null byte.
18966 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
18967 Truncate the output at a character boundary, since vsnprintf does not
18969 * charset.c (check_iso_charset_parameter): Convert internal
18970 character to string before calling 'error', since %c now has the
18972 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
18973 overflow when computing char to be passed to 'error'. Do not
18974 pass Lisp_Object to 'error'; pass the integer instead.
18975 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
18976 formatted with plain %d.
18978 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
18980 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
18982 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
18984 * xterm.c (x_catch_errors): Remove duplicate declaration.
18986 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
18988 * xdisp.c, lisp.h (message_nolog): Remove; unused.
18990 2011-04-10 Jim Meyering <meyering@redhat.com>
18992 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
18993 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
18994 return ssize_t not "int", and use size_t as the buffer length.
18995 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
18996 * gnutls.h: Update declarations.
18997 * process.c (read_process_output): Use ssize_t, to match.
18998 (send_process): Likewise.
19000 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19002 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
19004 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19006 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
19007 Use unsigned char, to match FcChar8 type definition.
19009 * xterm.c (handle_one_xevent):
19010 * xmenu.c (create_and_show_popup_menu):
19011 * xselect.c (x_decline_selection_request)
19012 (x_reply_selection_request): Avoid type-punned deref of X events.
19014 2011-04-09 Eli Zaretskii <eliz@gnu.org>
19016 Fix some uses of `int' instead of EMACS_INT.
19017 * search.c (string_match_1, fast_string_match)
19018 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
19019 (scan_buffer, find_next_newline_no_quit)
19020 (find_before_next_newline, search_command, Freplace_match)
19021 (Fmatch_data): Make some `int' variables be EMACS_INT.
19023 * xdisp.c (display_count_lines): 3rd argument and return value now
19024 EMACS_INT. All callers changed.
19025 (pint2hrstr): Last argument is now EMACS_INT.
19027 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
19028 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
19029 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

19040 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
19041 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
19043 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
19044 (encode_invocation_designation): Last argument P_NCHARS is now
19046 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
19047 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
19049 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
19052 * ccl.c (Fccl_execute_on_string): Declare some variables
19055 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
19057 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
19059 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
19061 * process.c (Fformat_network_address): Doc fix.
19063 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
19065 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
19067 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
19069 * keyboard.c (read_char): Call Lisp function help-form-show,
19070 instead of using internal_with_output_to_temp_buffer.
19071 (Qhelp_form_show): New var.
19072 (syms_of_keyboard): Use DEFSYM macro.
19074 * print.c (internal_with_output_to_temp_buffer): Function deleted.

19081 (list_processes_1): Delete.
19083 2011-04-06 Eli Zaretskii <eliz@gnu.org>
19085 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
19087 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
19089 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>

19106 printf-like functions.
19107 (tiff_load): Add casts to remove these marks before passing them
19108 to system-supplied API.
19110 * eval.c (Fsignal): Remove excess argument to 'fatal'.
19112 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
19113 This avoids several warnings with gcc -Wstrict-overflow.
19114 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
19115 directly, rather than having caller test rule sign. This avoids
19116 some unnecessary tests.
19117 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
19118 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
19119 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
19121 * xfont.c (xfont_text_extents): Remove var that was set but not used.
19122 (xfont_open): Avoid unnecessary tests.
19124 * composite.c (composition_gstring_put_cache): Use unsigned integer.
19126 * composite.h, composite.c (composition_gstring_put_cache):
19127 Use EMACS_INT, not int, for length.
19129 * composite.h (COMPOSITION_DECODE_REFS): New macro,
19130 breaking out part of COMPOSITION_DECODE_RULE.
19131 (COMPOSITION_DECODE_RULE): Use it.
19132 * composite.c (get_composition_id): Remove unused local vars,
19133 by using the new macro.
19135 * textprop.c (set_text_properties_1): Change while to do-while,
19136 since the condition is always true at first.
19138 * intervals.c (graft_intervals_into_buffer): Mark var as used.
19139 (interval_deletion_adjustment): Return unsigned value.
19142 * process.c (list_processes_1, create_pty, read_process_output):
19143 (exec_sentinel): Remove vars that were set but not used.
19144 (create_pty): Remove unnecessary "volatile"s.
19145 (Fnetwork_interface_info): Avoid possibility of int overflow.
19146 (read_process_output): Do adaptive read buffering even if carryover.
19147 (read_process_output): Simplify nbytes computation if buffered.

19151 * syntax.c (scan_words): Remove var that was set but not used.
19152 (update_syntax_table): Use unsigned instead of int.
19154 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
19155 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
19156 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
19158 * print.c (print_error_message): Avoid int overflow.
19160 * font.c (font_list_entities): Redo for clarity,
19161 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
19163 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
19164 (font_score): Avoid potential overflow in diff calculation.
19166 * fns.c (substring_both): Remove var that is set but not used.
19167 (sxhash): Redo loop for clarity and to avoid wraparound warning.
19169 * eval.c (funcall_lambda): Rename local to avoid shadowing.
19171 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
19172 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
19173 can always succeed if overflow has undefined behavior.
19175 * search.c (boyer_moore, wordify): Remove vars set but not used.
19176 (wordify): Omit three unnecessary tests.
19178 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
19179 All callers changed. This avoids the need for an unused var.
19181 * casefiddle.c (casify_region): Remove var that is set but not used.
19183 * dired.c (file_name_completion): Remove var that is set but not used.
19185 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
19187 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
19188 (Finsert_file_contents): Remove unnecessary code checking fd.
19190 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
19191 Check for integer overflow on size calculations.
19193 * buffer.c (Fprevious_overlay_change): Remove var that is set
19196 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
19197 Remove vars that are set but not used.
19198 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
19199 (timer_check_2): Mark vars as initialized.
19201 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
19203 * image.c (lookup_image): Remove var that is set but not used.
19204 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
19206 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
19207 that are set but not used.
19209 * xfns.c (make_invisible_cursor): Don't return garbage
19210 if XCreateBitmapFromData fails (Bug#8410).
19212 * xselect.c (x_get_local_selection, x_handle_property_notify):
19213 Remove vars that are set but not used.
19215 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
19216 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
19218 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
19219 Remove var that is set but not used.
19220 (scroll_bar_windows_size): Now size_t, not int.
19221 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
19222 Check for overflow.
19224 * xfaces.c (realize_named_face): Remove vars that are set but not used.
19225 (map_tty_color) [!defined MSDOS]: Likewise.
19227 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
19229 * coding.c: Remove vars that are set but not used.
19230 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
19231 All callers changed.
19232 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
19233 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
19234 (decode_coding_charset): Remove vars that are set but not used.
19236 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
19237 that is set but not used.
19239 * print.c (print_object): Remove var that is set but not used.
19241 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
19242 The gnulib version avoids calling malloc in the usual case,
19243 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
19244 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
19245 * filelock.c (current_lock_owner): Likewise.
19246 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
19247 * sysdep.c: Include allocator.h, careadlinkat.h.
19248 (emacs_no_realloc_allocator): New static constant.
19249 (emacs_readlink): New function.
19250 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
19251 ../lib/careadlinkat.h.
19253 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
19255 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
19256 first non-nil return value).
19258 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
19260 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
19261 if not defined (Bug#8403).
19263 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
19265 * xdisp.c (display_count_lines): Remove parameter `start',
19266 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
19267 (get_char_face_and_encoding): Remove parameter `multibyte_p',
19268 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

19270 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
19271 and thereabouts. All callers changed.
19272 (get_per_char_metric): Remove parameter `f', unused since
19273 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
19275 2011-04-02 Jim Meyering <meyering@redhat.com>
19277 do not dereference NULL upon failed strdup
19278 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
19279 (ns_get_family): Likewise.
19281 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
19283 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
19285 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
19287 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
19290 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
19292 Add lexical binding.
19294 * window.c (Ftemp_output_buffer_show): New fun.
19295 (Fsave_window_excursion):
19296 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
19298 * lread.c (lisp_file_lexically_bound_p): New function.
19299 (Fload): Bind Qlexical_binding.
19300 (readevalloop): Remove `evalfun' arg.
19301 Bind Qinternal_interpreter_environment.
19302 (Feval_buffer): Bind Qlexical_binding.
19303 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
19305 (syms_of_lread): Declare `lexical-binding'.
19307 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
19309 * keyboard.c (eval_dyn): New fun.
19310 (menu_item_eval_property): Use it.
19312 * image.c (parse_image_spec): Use Ffunctionp.
19314 * fns.c (concat, mapcar1): Accept byte-code-functions.
19316 * eval.c (Fsetq): Handle lexical vars.
19317 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
19318 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
19319 (FletX, Flet): Obey lexical binding.
19320 (Fcommandp): Handle closures.
19321 (Feval): New `lexical' arg.
19322 (eval_sub): New function extracted from Feval. Use it almost
19323 everywhere where Feval was used. Look up vars in lexical env.
19325 (Ffunctionp): Move from subr.el.
19326 (Ffuncall): Handle closures.
19327 (apply_lambda): Remove `eval_flags'.
19328 (funcall_lambda): Handle closures and new byte-code-functions.
19329 (Fspecial_variable_p): New function.
19330 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
19331 but without exporting it to Lisp.
19333 * doc.c (Fdocumentation, store_function_docstring):
19334 * data.c (Finteractive_form): Handle closures.
19336 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
19339 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
19341 (exec_byte_code): New function extracted from Fbyte_code to handle new
19342 calling convention for byte-code-functions. Add new byte-codes.
19344 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
19346 * alloc.c (Fmake_symbol): Init new `declared_special' field.
19348 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
19350 * xdisp.c (redisplay_internal): Fix prototype.
19352 2011-03-31 Eli Zaretskii <eliz@gnu.org>
19354 * xdisp.c (SCROLL_LIMIT): New macro.
19355 (try_scrolling): Use it when setting scroll_limit.
19356 Limit scrolling to 100 screen lines.
19357 (redisplay_window): Even when falling back on "recentering",
19358 position point in the window according to scroll-conservatively,
19359 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
19361 (try_scrolling): When point is above the window, allow searching
19362 as far as scroll_max, or one screenful, to compute vertical
19363 distance from PT to the scroll margin position. This prevents
19364 try_scrolling from unnecessarily failing when
19365 scroll-conservatively is set to a value slightly larger than the
19366 window height. Clean up the case of PT below the margin at bottom
19367 of window: scroll_max can no longer be INT_MAX. When aggressive
19368 scrolling is in use, don't let point enter the opposite scroll
19369 margin as result of the scroll.
19370 (syms_of_xdisp) <scroll-conservatively>: Document the
19371 threshold of 100 lines for never-recentering scrolling.
19373 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
19375 * dispextern.h (move_it_by_lines):
19376 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused

19378 (message_log_check_duplicate): Remove parameters `prev_bol' and
19379 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
19380 (redisplay_internal): Remove parameter `preserve_echo_area',
19381 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
19383 * indent.c (Fvertical_motion):
19384 * window.c (window_scroll_pixel_based, Frecenter):
19385 Don't pass `need_y_p' to `move_it_by_lines'.
19387 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
19389 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
19390 steal a few bits to be more compact.
19391 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
19392 Remove unneeded casts.
19394 * bytecode.c (Fbyte_code): CAR and CDR can GC.
19396 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
19398 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
19399 binding" message (bug#7967).
19401 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
19403 Fix more problems found by GCC 4.6.0's static checks.
19405 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
19406 Remove unused local var.
19408 * editfns.c (Fmessage_box): Remove unused local var.
19410 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
19411 (note_mode_line_or_margin_highlight, note_mouse_highlight):
19412 Omit unused local vars.
19413 * window.c (shrink_windows): Omit unused local var.
19414 * menu.c (digest_single_submenu): Omit unused local var.
19415 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
19416 Omit unused local var.
19418 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
19419 Don't assume string length fits in int.
19420 (keyremap_step, read_key_sequence): Use size_t for sizes.
19421 (read_key_sequence): Don't check last_real_key_start redundantly.
19423 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
19424 instead of alloca (Bug#8344).
19426 * eval.c (Fbacktrace): Don't assume nargs fits in int.
19427 (Fbacktrace_frame): Don't assume nframes fits in int.
19429 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
19431 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
19434 * term.c (produce_glyphless_glyph): Remove unnecessary test.
19436 * cm.c (calccost): Turn while-do into do-while, for clarity.
19438 * keyboard.c (syms_of_keyboard): Use the same style as later
19439 in this function when indexing through an array. This also
19440 works around GCC bug 48267.
19442 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
19444 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
19446 * chartab.c (sub_char_table_ref_and_range): Redo for slight
19447 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
19449 * keyboard.c, keyboard.h (num_input_events): Now size_t.
19450 This avoids undefined behavior on integer overflow, and is a bit
19451 more convenient anyway since it is compared to a size_t variable.
19453 Variadic C functions now count arguments with size_t, not int.
19454 This avoids an unnecessary limitation on 64-bit machines, which
19455 caused (substring ...) to crash on large vectors (Bug#8344).
19456 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
19457 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

19465 * fns.c (concat): Likewise.
19466 * frame.c (x_set_frame_parameters): Likewise.
19467 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
19468 0 if not found, not -1. All callers changed.
19470 * alloc.c (garbage_collect): Don't assume stack size fits in int.
19471 (stack_copy_size): Now size_t, not int.
19472 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
19474 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
19476 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
19477 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
19478 All callers changed.
19480 * lisp.h (multibyte_char_to_unibyte):
19481 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
19482 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

19490 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
19492 * keyboard.c (safe_run_hook_funcall): New function.
19493 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
19494 don't set the hook to nil, but remove the offending function instead.
19495 (Qcommand_hook_internal): Remove, unused.
19496 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
19497 Vcommand_hook_internal.
19499 * eval.c (enum run_hooks_condition): Remove.
19500 (funcall_nil, funcall_not): New functions.
19501 (run_hook_with_args): Call each function through a `funcall' argument.
19502 Remove `cond' argument, now redundant.

19504 (Frun_hook_with_args_until_failure): Adjust accordingly.
19505 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.

19511 * print.c (strout): Remove parameter `multibyte', unused since
19512 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
19514 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
19515 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
19516 All callers changed.
19518 * w32.c (_wsa_errlist): Use braces for struct initializers.
19520 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
19521 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
19522 All callers changed.

19677 * buffer.c (Fkill_all_local_variables):
19678 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
19680 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
19681 unconditionally since it does the check itself.
19683 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
19685 Fix more problems found by GCC 4.5.2's static checks.
19687 * coding.c (encode_coding_raw_text): Avoid unnecessary test
19688 the first time through the loop, since we know p0 < p1 then.
19689 This also avoids a gcc -Wstrict-overflow warning.
19691 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
19692 leading to a memory leak, possible in functions like
19693 load_charset_map_from_file that can allocate an unbounded number
19694 of objects (Bug#8318).
19696 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
19697 that could (at least in theory) be that large.
19699 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
19700 This is less likely to overflow, and avoids undefined behavior if
19701 overflow does occur. All callers changed. Use strtoul to scan
19702 for the unsigned long integer.
19703 (pint2hrstr): Simplify and tune code slightly.
19704 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

19719 * process.c (Fmake_network_process): Use socklen_t, not int,
19720 where POSIX says socklen_t is required in portable programs.
19721 This fixes a porting bug on hosts like 64-bit HP-UX, where
19722 socklen_t is wider than int (Bug#8277).
19723 (Fmake_network_process, server_accept_connection):
19724 (wait_reading_process_output, read_process_output):
19727 * process.c: Rename or move locals to avoid shadowing.

19737 Make tparam.h and terminfo.c consistent.
19738 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
19739 Include tparam.h instead, since it declares them.
19740 * cm.h (PC): Remove extern decl; tparam.h now does this.
19741 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
19742 * terminfo.c: Include tparam.h, to check interfaces.
19743 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
19744 (tparam): Adjust signature to match interface in tparam.h;
19745 this removes some undefined behavior. Check that outstring and len
19746 are zero, which they always are with Emacs.
19747 * tparam.h (PC, BC, UP): New extern decls.
19749 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
19750 (xftfont_open): Rename locals to avoid shadowing.
19752 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

19767 (find_automatic_composition, composition_adjust_point): Likewise.
19768 (composition_update_it): Mark var as initialized.
19769 (find_automatic_composition): Mark vars as initialized,
19770 with a FIXME (Bug#8290).

19774 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
19775 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
19776 (BUF_DEC_POS): Be more systematic about renaming local temporaries
19777 to avoid shadowing.
19779 * textprop.c (property_change_between_p): Remove; unused.
19781 * intervals.c (interval_start_pos): Now static.
19783 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

19789 Fix pointer signedness.
19790 (alsa_choose_format): Remove unused local var.
19791 (wav_play): Initialize a variable to 0, to prevent undefined
19792 behavior (Bug#8278).
19794 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
19796 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
19798 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
19799 clobbering (Bug#8298).
19800 * sysdep.c (sys_subshell): Likewise.
19801 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
19803 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
19804 This should get cleaned up, so that child_setup has the
19805 same signature on all platforms.
19807 * callproc.c (call_process_cleanup): Now static.
19808 (relocate_fd): Rename locals to avoid shadowing.
19810 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
19812 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
19813 not to be necessary, and produces flickering.
19815 2011-03-20 Glenn Morris <rgm@gnu.org>
19817 * config.in: Remove file.
19819 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
19821 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
19822 are now in src/globals.h.

19864 Define only if needed.
19866 * unexelf.c (unexec): Name an expression,
19867 to avoid gcc -Wbad-function-cast warning.
19868 Use a different way to cause a compilation error if anyone uses
19869 n rather than nn, a way that does not involve shadowing.
19870 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
19872 * deps.mk (unexalpha.o): Remove; unused.
19874 New file unexec.h, the (simple) interface for unexec (Bug#8267).

19996 (WORDCHAR_P): Likewise. This one is never needed, but is used
19997 only in a comment talking about a compiler bug, so put inside
19998 the #if 0 of that comment.
19999 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
20000 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

20028 gcpro1, gcpro2, etc.
20029 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
20031 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second

20036 Rename locals to avoid shadowing.
20038 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).

20042 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...

20044 and the new implementation with inline functions needs to have
20045 current_buffer in scope now, rather than later when the macros
20047 (downcase, upcase1): New static inline functions.
20048 (DOWNCASE, UPCASE1): Reimplement using these functions.
20049 This avoids undefined behavior in expressions like
20050 DOWNCASE (x) == DOWNCASE (y), which previously suffered

20083 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.

20090 * buffer.c (fix_overlays_before): Mark locals as initialized.
20091 (fix_start_end_in_overlays): Likewise. This function should be
20092 simplified by using pointers-to-pointers, but that's a different

20095 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
20096 (report_overlay_modification): Rename locals to avoid shadowing.

20101 to suppress a gcc -Wclobbered warning that does not seem to be right.
20102 (MAXPATHLEN): Define only if needed.
20104 * process.c (serial_open, serial_configure): Move decls from here ...
20105 * systty.h: ... to here, so that they can be checked.
20107 * fns.c (get_random, seed_random): Move extern decls from here ...
20108 * lisp.h: ... to here, so that they can be checked.
20110 * sysdep.c (reset_io): Now static.
20111 (wait_for_termination_signal): Remove; unused.
20113 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
