3 * w32.c (unsetenv): Return 0 if the input string is too long.
5 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
7 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).
8 * alloc.c (xputenv): New function.
9 * dbusbind.c (Fdbus_init_bus):
11 * xterm.c (x_term_init):
12 Use xputenv instead of setenv or putenv, to detect memory exhaustion.
13 * editfns.c (initial_tz): Move static var decl up.
14 (tzvalbuf_in_environ): New static var.
15 (init_editfns): Initialize these two static vars.
16 (Fencode_time): Don't assume arbitrary limit on EMACS_INT width.
17 Save old TZ value on stack, if it's small.
18 (Fencode_time, set_time_zone_rule): Don't modify 'environ' directly;
19 instead, use xputenv+unsetenv to set and restore TZ.
20 (environbuf): Remove static var. All uses removed.
21 (Fset_time_zone_rule): Do not save TZ and environ;
22 no longer needed here.
23 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
24 Move to inside set_time_zone_rule; they don't need file scope any more.
25 (set_time_zone_rule): Maintain the TZ=value string separately.
26 (syms_of_editfns): Don't initialize initial_tz;
27 init_editfns now does it.
28 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
29 * lisp.h (xputenv): New decl.
31 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
33 * w32fns.c (emacs_abort): Don't do arithmetics on void pointers.
35 2012-12-08 Eli Zaretskii <eliz@gnu.org>
37 * w32.c (unsetenv, sys_putenv): New functions.
39 2012-12-08 Chong Yidong <cyd@gnu.org>
41 * editfns.c (Finsert_char): Make the error message more
42 informative (Bug#12992).
44 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
46 Simplify get_lim_data.
47 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
48 Remove USG and vlimit methods; no longer used these days.
49 Add #error catchall just in case.
51 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
52 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
53 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
54 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
55 (deleted_pid_list, Fdelete_process, create_process)
56 (record_child_status_change, handle_child_signal, deliver_child_signal)
57 (init_process_emacs, syms_of_process):
58 Assume SIGCHLD is defined.
59 (parse_signal): Remove. All uses removed.
60 (abbr_to_signal): New static function.
61 (Fsignal_process): Use it to convert signal names to ints.
62 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
63 kill (getpgrp (), ...).
64 (emacs_sigaction_init): Assume SIGCHLD is defined.
65 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,
66 SIGPIPE, and SIGQUIT are defined. Do not worry about SIGCLD any more.
67 * syssignal.h (EMACS_KILLPG): Remove.
68 All uses replaced by 'kill' with a negative pid.
69 (SIGCHLD): Remove definition, as we now assume SIGCHLD.
70 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
72 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
74 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
75 This will cause a production Emacs to dump core instead of
78 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
80 * frame.c (make_frame): Do not set window's buffer to t.
81 * window.c (Fsplit_window_internal): Likewise. Previously it was
82 used to indicate that the window is being set up. Now we use
83 set_window_buffer for all new windows, so the condition in ...
84 (Fset_window_buffer): ... is always true and can be removed.
86 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
88 Convenient macro to check whether the buffer is hidden.
89 * buffer.h (BUFFER_HIDDEN_P): New macro.
90 * frame.c (make_frame): Use it. Adjust comment.
91 * buffer.c (candidate_buffer): New function.
92 (Fother_buffer, other_buffer_safely): Use it.
94 2012-12-06 Eli Zaretskii <eliz@gnu.org>
96 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
97 if the child process is still running. Instead, exit the wait
98 loop and return zero. (Bug#13086)
100 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
102 * frame.h (x_char_width, x_char_height): Remove prototypes.

111 (command_loop_2, top_level_1): Add static to match prototype.
113 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
115 Fix a recently-introduced delete-process race condition.
116 * callproc.c, process.h (record_kill_process):
117 New function, containing part of the old call_process_kill.
118 (call_process_kill): Use it.
119 This does not change call_process_kill's behavior.
120 * process.c (Fdelete_process): Use record_kill_process to fix a
121 race condition that could cause Emacs to lose track of a child.
123 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
125 Avoid code duplication between prev_frame and next_frame.
126 * frame.c (candidate_frame): New function. Add comment.
127 (prev_frame, next_frame): Use it. Adjust comment.
129 2012-12-06 Eli Zaretskii <eliz@gnu.org>
131 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
132 fails, signal an error instead of continuing with an empty
134 Encode expanded temp file pattern before passing it to mkstemp or
137 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
138 Encode the file name before passing it to dostounix_filename, in
139 case it will downcase it (under w32-downcase-file-names).
142 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
144 Minor call-process cleanups.
145 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
146 at the same time as other platforms, to simplify analysis.
147 No need for fd0_volatile since we have synch_process_fd.
148 Avoid needless emacs_close; arg is always negative.
150 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
152 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
155 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
157 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
158 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
159 and mouse_face_hidden members to a bitfields.
160 * frame.h (struct frame): Remove set-but-not-used space_width member.
161 (FRAME_SPACE_WIDTH): Remove.
162 * nsterm.m, w32term.c, xterm.c: Adjust users.
163 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
164 member. Adjust users. Convert term_initted, delete_in_insert_mode,
165 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
166 members to a bitfields.
168 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
170 Don't let call-process be a zombie factory (Bug#12980).
171 Fixing this bug required some cleanup of the signal-handling code.
172 As a side effect, this change also fixes a longstanding rare race
173 condition whereby Emacs could mistakenly kill unrelated processes,
174 and it fixes a bug where a second C-g does not kill a recalcitrant
175 synchronous process in GNU/Linux and similar platforms.
176 The patch should also fix the last vestiges of Bug#9488,
177 a bug which has mostly been fixed on the trunk by other changes.
178 * callproc.c, process.h (synch_process_alive, synch_process_death)
179 (synch_process_termsig, sync_process_retcode):
180 Remove. All uses removed, to simplify analysis and so that
181 less consing is done inside critical sections.
182 * callproc.c (call_process_exited): Remove. All uses replaced
183 with !synch_process_pid.
184 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
185 These take the role of what used to be in unwind-protect arg.
187 (block_child_signal, unblock_child_signal):
188 New functions, to avoid races that could kill innocent-victim processes.
189 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
190 (call_process_kill): Record killed processes as deleted, so that
191 zombies do not clutter up the system. Do this inside a critical
192 section, to avoid a race that would allow the clutter.
193 (call_process_cleanup): Fix code so that the second C-g works again
194 on common platforms such as GNU/Linux.
195 (Fcall_process): Create the child process in a critical section,
196 to fix a race condition. If creating an asynchronous process,
197 record it as deleted so that zombies do not clutter up the system.
198 Do unwind-protect for WINDOWSNT too, as that's simpler in the
199 light of these changes. Omit unnecessary call to emacs_close
200 before failure, as the unwind-protect code does that.
201 * callproc.c (call_process_cleanup):
202 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
203 * process.c (record_deleted_pid): New function, containing
204 code refactored out of Fdelete_process.
205 (Fdelete_process): Use it.
206 (process_status_retrieved): Remove. All callers changed to use
208 (record_child_status_change): Remove, folding its contents into ...
209 (handle_child_signal): ... this signal handler. Now, this
210 function is purely a handler for SIGCHLD, and is not called after
211 a synchronous waitpid returns; the synchronous code is moved to
212 wait_for_termination. There is no need to worry about reaping
213 more than one child now.
214 * sysdep.c (get_child_status, child_status_changed): New functions.
215 (wait_for_termination): Now takes int * status and bool
216 interruptible arguments, too. Do not record child status change;
217 that's now the caller's responsibility. All callers changed.
218 Reimplement in terms of get_child_status.
219 (wait_for_termination_1, interruptible_wait_for_termination):
220 Remove. All callers changed to use wait_for_termination.
221 * syswait.h: Include <stdbool.h>, for bool.
222 (record_child_status_change, interruptible_wait_for_termination):
224 (record_deleted_pid, child_status_changed): New decls.
225 (wait_for_termination): Adjust to API changes noted above.
227 * bytecode.c, lisp.h (Qbytecode): Remove.
228 No longer needed after 2012-11-20 interactive-p changes.
230 2012-12-03 Eli Zaretskii <eliz@gnu.org>
232 * xdisp.c (redisplay_window): If the cursor is visible, but inside
233 the scroll margin, move point outside the margin. (Bug#13055)
235 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
237 * gtkutil.c (my_log_handler): New function.
238 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
240 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
242 * lisp.h (modify_region): Rename to...
243 (modify_region_1): ...new prototype.
244 * textprop.c (modify_region): Now static. Adjust users.
245 * insdel.c (modify_region): Rename to...
246 (modify_region_1): ...new function to work with current buffer.
247 Adjust comment and users. Use true and false for booleans.
249 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
251 * alloc.c (free_save_value): New function.
252 (safe_alloca_unwind): Use it.
253 * lisp.h (free_save_value): New prototype.
254 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
256 (save_excursion_restore): Adjust to match saved data structure.
257 Use free_save_value to offload some work from GC. Drop obsolete
260 2012-12-03 Chong Yidong <cyd@gnu.org>
262 * fileio.c (Vauto_save_list_file_name): Doc fix.
264 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
266 * w32fns.c: Remove prototype of atof.
267 (syspage_mask): Declared DWORD_PTR, for compatibility with 64-bit
269 (file_dialog_callback): Declared UINT_PTR.
271 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
274 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
275 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
278 2012-12-03 Glenn Morris <rgm@gnu.org>
280 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
282 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
284 Fix xpalloc confusion after memory is exhausted.
285 * alloc.c (xpalloc): Comment fix.
286 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
287 and signals an error, do not clear charset_table_size, as
288 charset_table is still valid.
289 * doprnt.c (evxprintf): Clear *BUF after freeing it.
291 Use execve to avoid need to munge environ (Bug#13054).
292 * callproc.c (Fcall_process):
293 * process.c (create_process):
294 Don't save and restore environ; no longer needed.
295 * callproc.c (child_setup):
296 Use execve, not execvp, to preserve environ.
298 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
300 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
302 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
304 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
305 display for sliced images (Bug#10500).
307 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
309 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
311 * doc.c (Fdocumentation): Re-add handling of function-documentation,
312 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
314 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
316 * xdisp.c (window_outdated): Remove eassert since it hits
317 some suspicious corner cases (see Bug#13007 and Bug#13012).
318 (mode_line_update_needed): New function.
319 (redisplay_internal, redisplay_window): Use it.
320 (ensure_selected_frame): New function.
321 (redisplay_internal, unwind_redisplay): Use it.
322 (redisplay_internal): Move comment about buffer_shared...
323 (buffer_shared_and_changed): ...near to its real use.
325 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
327 * callproc.c (Fcall_process): Don't misreport vfork failure.
329 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
331 * callproc.c (Fcall_process): Fix vfork portability problems.
332 Do not assume that fd[0], count, filefd, and save_environ survive
333 vfork. Fix bug whereby wrong errno value could be reported for
334 pipe failure. Some minor cleanups, too, as follows. Move buf and
335 bufsize to the context where they're needed. Change new_argv to
336 be of type char **, as this is more convenient and avoids casts.
337 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
338 Now local constants, not macros.
340 2012-11-18 Kenichi Handa <handa@gnu.org>
342 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
343 for the variable "f".
345 2012-11-13 Kenichi Handa <handa@gnu.org>
347 * font.c (font_unparse_xlfd): Exclude special characters from the
348 generating XLFD name.

366 * unexcoff.c (write_segment): Assume EFAULT is defined.
368 2012-11-27 Eli Zaretskii <eliz@gnu.org>
370 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
373 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
374 highlighting on the frame was cleared. Prevents assertion
375 violations when repeatedly clicking on the "Top" link of the
376 "bread-crumbs" in Info buffers.

390 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
391 between bpos_covered and bpos_max. This fixes cursor display when
392 several display strings follow each other.
394 * .gdbinit (pgx): If the glyph's object is a string, display the
395 pointer to string data, rather than the value of the string object
396 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
398 * indent.c (Fvertical_motion): If the starting position is covered
399 by a display string, return to one position before that, to avoid
400 overshooting it inside move_it_to. (Bug#12930)
402 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
404 * frame.h (struct frame): Remove display_preempted member

412 asked_for_visible and menubar_active members. Drop
413 unused pending_menu_activation member.
414 * xterm.h (struct x_output): Drop outdated #if 0 code.
415 Use bitfields for explicit_parent, asked_for_visible,
416 has_been_visible and net_wm_state_hidden_seen members.
418 2012-11-23 Eli Zaretskii <eliz@gnu.org>

421 of a literal "/". (Bug#12955)
422 (gl-stamp): Invoke fc.exe directly, not through cmd.

428 (NAMLEN): Remove, replacing with ...
429 (dirent_namelen): New function. All uses changed. Use the GNU macro
430 _D_EXACT_NAMELEN if available, as it's faster than strlen.
431 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
432 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
433 * makefile.w32-in (DIR_H): Remove. All uses replaced with
435 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
436 * ndir.h: Rename to ../nt/inc/dirent.h.
437 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
438 Do not include <dirent.h>; no longer needed.
439 * w32.c: Include <dirent.h> rather than "ndir.h".
441 2012-11-23 Chong Yidong <cyd@gnu.org>
443 * xftfont.c (xftfont_open): Remove duplicate assignment.
445 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
447 * alloc.c (Fgarbage_collect): Unblock input after clearing
448 gc_in_progress to avoid note_mouse_highlight glitch with GC.
449 * frame.h (FRAME_MOUSE_UPDATE): New macro.
450 * msdos.c (IT_frame_up_to_date): Use it here...
451 * w32term.c (w32_frame_up_to_date): ...here...
452 * xterm.c (XTframe_up_to_date): ...and here...
453 * nsterm.m (ns_frame_up_to_date): ...but not here.
454 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
456 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
457 Do not check whether GC is in progress.
459 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
461 * xdisp.c (window_buffer_changed): New function.
462 (update_menu_bar, update_tool_bar): Use it to
463 simplify large 'if' statements.
464 (redisplay_internal): Generalize commonly used
465 'tail' and 'frame' local variables.
467 2012-11-22 Eli Zaretskii <eliz@gnu.org>
469 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
470 with Windows system header.
472 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
474 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
475 * alloc.c: Assume unistd.h exists.
476 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
477 * sysdep.c (get_current_dir_name): Assume getcwd exists.
478 (getwd) [USG]: Remove; no longer needed.

481 * w32.h (getcwd): Remove decl.
483 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
485 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
486 Make it set selected_window as well.
487 (update_tool_bar): Use it.
489 2012-11-21 Ken Brown <kbrown@cornell.edu>
491 * emacs.c (main): Set the G_SLICE environment variable for all
492 Cygwin builds, not just GTK builds. See
493 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
495 2012-11-21 Eli Zaretskii <eliz@gnu.org>
497 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
498 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
499 Define for the MSVC compiler.
501 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
503 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
504 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
505 dostounix_filename. Prevents crashes down the road, because
506 dostounix_filename assumes it gets a unibyte string. Reported by
507 Michel de Ruiter <michel@sentient.nl>, see
508 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
510 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>

514 * lread.c (init_obarray): Set `function' fields to Qnil.
515 * eval.c (Fcommandp): Ignore Qunbound.
516 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
517 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
518 Test NILP rather than Qunbound.
519 (Ffmakunbound): Set to Qnil.
520 (Fsymbol_function): Never signal an error.
521 (Finteractive_form): Ignore Qunbound.
523 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
525 * eval.c (interactive_p): Remove no-longer-used decl.
527 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
529 * xdisp.c (buffer_shared): Adjust comment.
530 (buffer_shared_and_changed): New function.
531 (prepare_menu_bars, redisplay_internal): Use it to
532 decide whether all windows or frames should be updated.
533 (window_outdated): New function.
534 (text_outside_line_unchanged_p, redisplay_window): Use it.
535 (redisplay_internal): Likewise. Fix indentation.
537 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
539 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
540 (syms_of_eval): Remove corresponding defsubr.
541 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
543 2012-11-19 Daniel Colascione <dancol@dancol.org>
545 * w32fns.c (Fx_file_dialog):
546 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
547 cygwin_convert_file_name*.
549 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
550 Rename cygwin_convert_path* to cygwin_convert_file_name*.
552 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
554 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
556 2012-11-18 Eli Zaretskii <eliz@gnu.org>
558 * w32select.c: Include w32common.h before w32term.h, so that
559 windows.h gets included before w32term.h uses some of its
562 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
564 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
566 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
568 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
570 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
571 (ns_select): Return at once if events are held (Bug#12834).
573 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
575 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
576 Needed following 2012-10-20 change. (Bug#12902)
578 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
580 * w32proc.c (waitpid): Remove unused label get_result.
582 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
584 * makefile.w32-in (SYSWAIT_H): New macro.
585 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
586 ($(BLD)/sysdep.$(O)): Update dependencies.
588 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
590 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
591 * callproc.c (relocate_fd): Assume F_DUPFD.
592 * emacs.c, term.c (O_RDWR): Remove.
593 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
594 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
595 * nsterm.m: Assume <fcntl.h> exists.
596 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
597 (create_pty, Fmake_network_process, server_accept_connection)
598 (wait_reading_process_output, init_process_emacs):
600 (wait_reading_process_output): Put in a special case for WINDOWSNT
601 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
602 It's not clear this is needed, but it's a more-conservative change.
603 (create_process): Assume FD_CLOEXEC.
604 (create_process, create_pty): Assume O_NOCTTY.
605 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
606 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
607 Omit if not DOS_NT, since F_GETFL is not defined there.
608 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
609 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
611 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
612 lack it, since gnulib guarantees this.
613 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
615 2012-11-17 Eli Zaretskii <eliz@gnu.org>
617 * w32.c (faccessat): Pretend that directories have the execute bit
618 set. Emacs expects that, e.g., in files.el:cd-absolute.
620 * w32proc.c (create_child): Don't clip the PID of the child
621 process to fit into an Emacs integer, as this is no longer a
623 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
624 reaping only the process specified by PID argument, if that is
625 positive. Use PID instead of dead_child to know which process to
626 reap. Wait for the child to die only if WNOHANG is not in
628 (sys_select): Don't set dead_child.
630 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
631 as it is no longer needed.
633 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
635 (record_child_status_change): Remove the setting of
636 record_at_most_one_child for the !WNOHANG case.
638 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
640 Fix problems in ns port found by static checking.
641 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
642 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
643 not to process group.
644 (ns_select): Use emacs_write, not write, as that's more robust
645 in the presence of signals.
646 (fd_handler:): Check for read errors.
648 2012-11-16 Glenn Morris <rgm@gnu.org>
650 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
652 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
654 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
656 2012-11-16 Eli Zaretskii <eliz@gnu.org>
658 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
659 use the same value of thread handle.
660 (start_timer_thread): If the timer thread exited (due to error),
661 clean up by closing the two handles it used. Duplicate the caller
662 thread's handle here, so it gets duplicated only once, when
663 launching the timer thread. Set priority of the timer thread, not
665 (getitimer): Don't duplicate the caller thread's handle here.
668 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
670 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
673 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
675 Remove no-longer-used pty_max_bytes variable.
676 * process.c (pty_max_bytes): Remove; unused.
677 (send_process): Do not set it.
679 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
681 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
684 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
686 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
687 This follows up on the 2012-09-29 patch that removed indirection
688 for the 'function' field. Reported by Sergey Vinokurov in
689 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
691 2012-11-14 Eli Zaretskii <eliz@gnu.org>
693 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
694 different name, as the MS runtime does not have such a function,
695 and probably never will.) All callers changed. Ignore DIRFD
696 value if PATH is an absolute file name, to match Posix spec
697 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
700 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
702 * xdisp.c (echo_area_display, redisplay_internal):
703 Omit redundant check whether frame_garbaged is set.
705 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
707 Use faccessat, not access, when checking file permissions (Bug#12632).
708 This fixes a bug that has been present in Emacs since its creation.
709 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
710 which must set some sort of record. (Torek's bug report was against
711 a predecessor of GNU Emacs, but GNU Emacs happened to have the
712 same common flaw.) See Torek's Usenet posting
713 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
714 Posted: Fri Apr 8 14:18:56 1983.
715 * Makefile.in (LIB_EACCESS): New macro.
717 * callproc.c (init_callproc):
718 * charset.c (init_charset):
719 * fileio.c (check_existing, check_executable, check_writable)
721 * lread.c (openp, load_path_check):
722 * process.c (allocate_pty):
724 Use effective UID when checking permissions, not real UID.
725 * callproc.c (init_callproc):
726 * charset.c (init_charset):
727 * lread.c (load_path_check, init_lread):
728 Test whether directories are accessible, not merely whether they exist.
729 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
730 * fileio.c (check_existing, check_executable, check_writable)
732 Use symbolic names instead of integers for the flags, as they're
734 (check_writable): New arg AMODE. All uses changed.
735 Set errno on failure.
736 (Ffile_readable_p): Use faccessat, not stat + open + close.
737 (Ffile_writable_p): No need to call check_existing + check_writable.
738 Just call check_writable and then look at errno. This saves a syscall.
739 dir should never be nil; replace an unnecessary runtime check
740 with an eassert. When checking the parent directory of a nonexistent
741 file, check that the directory is searchable as well as writable, as
742 we can't create files in unsearchable directories.
743 (file_directory_p): New function, which uses 'stat' on most platforms
744 but faccessat with D_OK (for efficiency) if WINDOWSNT.
745 (Ffile_directory_p, Fset_file_times): Use it.
746 (file_accessible_directory_p): New function, which uses a single
747 syscall for efficiency.
748 (Ffile_accessible_directory_p): Use it.
749 * xrdb.c (file_p): Use file_directory_p.
750 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
751 * lread.c (openp): When opening a file, use fstat rather than
752 stat, as that avoids a permissions race. When not opening a file,
753 use file_directory_p rather than stat.
754 (dir_warning): First arg is now a usage string, not a format.
755 Use errno. All uses changed.
756 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
757 that merely introduced a race.
758 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
759 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
760 and similarly for the other O_* flags.
761 * w32.c (sys_faccessat): Rename from sys_access and switch to
762 faccessat's API. All uses changed.
763 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
764 (magic_db): Rename from magic_file_p.
765 (magic_db, search_magic_path): Return an XrmDatabase rather than a
766 char *, so that we don't have to test for file existence
767 separately from opening the file for reading. This removes a race
768 fixes a permission-checking problem, and simplifies the code.
770 (file_p): Remove; no longer needed.
772 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
774 Omit glyphs initialization at startup.
775 * dispnew.c (glyphs_initialized_initially_p): Remove.
776 (adjust_frame_glyphs_initially): Likewise. Adjust users.
777 (Fredraw_frame): Move actual code from here...
778 (redraw_frame): ...to here. Add eassert. Adjust comment.
779 (Fredraw_display): Use redraw_frame.
780 * xdisp.c (clear_garbaged_frames): Likewise.
782 2012-11-13 Eli Zaretskii <eliz@gnu.org>
784 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
785 passed to pint2str and pint2hrstr to be at most the size of the
786 frame's decode_mode_spec_buffer. This avoids crashes with very
787 large values of FIELD_WIDTH argument to decode_mode_spec.
790 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
792 Fix a race with verify-visited-file-modtime (Bug#12863).
793 Since at least 1991 Emacs has ignored an mtime difference of no
794 more than one second, but my guess is that this was to work around
795 file system bugs that were fixed long ago. Since the race is
796 causing problems now, let's remove that code.
797 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
798 whose time stamp is off by no more than a second. Insist that the
799 file time stamps match exactly.
801 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
803 * frame.h (struct frame): Convert external_tool_bar member to
804 1-bit unsigned bitfield.
805 * termhooks.h (struct terminal): Remove mouse_moved member since
806 all users are long dead. Adjust comment on mouse_position_hook.
808 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
810 Simplify by using FOR_EACH_FRAME here and there.
811 * frame.c (next_frame, prev_frame, other_visible_frames)
812 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
813 * w32term.c (x_window_to_scroll_bar): Likewise.
814 * window.c (window_list): Likewise.
815 * xdisp.c (x_consider_frame_title): Likewise.
816 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
817 * xfns.c (x_window_to_frame, x_any_window_to_frame)
818 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
819 * xmenu.c (menubar_id_to_frame): Likewise.
820 * xselect.c (frame_for_x_selection): Likewise.
821 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
822 (x_window_to_menu_bar): Likewise.
823 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
825 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
827 * data.c (Qdefalias_fset_function): Now static.
829 Another tweak to vectorlike_header change.
830 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
831 Remove, and replace all uses with ...
832 (next_in_free_list, set_next_in_free_list):
833 New functions, which respect C's aliasing rules better.
835 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
837 * window.c (list4i): Rename from 'quad'. All uses changed.
838 Needed because <sys/types.h> defines 'quad' on Solaris 10.
840 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
842 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
843 warning about mixing declarations and code in ISO C90.
845 2012-11-10 Martin Rudalics <rudalics@gmx.at>
847 * window.c (Fsplit_window_internal): Set combination limit of
848 new parent window to t iff Vwindow_combination_limit is t;
849 fixing a regression introduced with the change from 2012-09-22.
850 (Fset_window_combination_limit): Fix doc-string.
852 2012-11-10 Eli Zaretskii <eliz@gnu.org>
854 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
855 amount when the scroll margins are too large. When scrolling
856 backwards in the buffer, give up if cannot reach point or the
857 scroll margin within a reasonable number of screen lines.
858 Fixes point position in window under scroll-up/down-aggressively when
859 point is positioned many lines beyond the window top/bottom.
862 * ralloc.c (relinquish): If real_morecore fails to return memory
863 to the system, don't crash; instead, leave the last heap
864 unchanged and return. (Bug#12774)
866 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
868 * lisp.h (AUTOLOADP): New macro.
869 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
870 * data.c (Ffset): Remove special ad-advice-info handling.
871 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
873 (Finteractive_form): Simplify.
874 (Fquo): Don't insist on having at least 2 arguments.
875 (Qdefalias_fset_function): New var.
877 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
879 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
881 * nsfont.m (Qcondensed, Qexpanded): New variables.
882 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
883 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
885 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
887 Fix recently introduced crash on MS-Windows (Bug#12839).
888 * w32term.h (struct scroll_bar): Use convenient header.
889 (SCROLL_BAR_VEC_SIZE): Remove.
890 * w32term.c (x_scroll_bar_create): Use VECSIZE.
892 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
894 Tweak last vectorlike_header change.
895 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
896 vectorlike object on the free list. This is introduced to avoid
897 some (but not all) pointer casting and aliasing problems, see
898 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
899 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
901 (xvectype, xvecsize): Use them to examine Lisp_Object values.
903 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
905 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
906 been removed, so remove them here also.
908 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
910 * doc.c (Fdocumentation): Handle new property
911 dynamic-docstring-function to replace the old ad-advice-info.
913 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
915 * fns.c (Qeql, hashtest_eq): Now static.
917 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
919 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
920 * fns.c (hashfn_eq, hashfn_eql, sxhash):
921 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
922 * buffer.c (compare_overlays): Use XLI rather than XHASH.
924 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
926 Use same hash function for hashfn_profiler as for hash_string etc.
927 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
928 * lisp.h (sxhash_combine): New inline function, with the contents
929 of the old SXHASH_COMBINE.
930 * profiler.c (hashfn_profiler): Use it, instead of having a
931 special hash function containing a comparison that always yields 1.
933 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
935 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
936 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
937 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
940 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
942 * image.c (xpm_make_color_table_h): Fix compiler error because
943 make_hash_table changed.
945 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
947 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
949 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
951 Use ad-hoc comparison function for the profiler's hash-tables.
952 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
953 (make_log): Use them.
954 (handle_profiler_signal): Don't inhibit quit any longer since we don't
955 call Fequal any more.

963 (cmpfn_eql, cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
964 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
965 (hash_lookup, hash_remove_from_table): Move assertion checking of
966 hashfn result here. Check hash-equality before calling cmpfn.

968 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.
969 (syms_of_fns): Initialize them.

976 2012-11-08 Eli Zaretskii <eliz@gnu.org>
978 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
979 value of w32-scroll-lock-modifier is neither nil nor one of the
980 known key modifiers. (Bug#12806)
982 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
984 Shrink struct vectorlike_header to the only size field.
985 * lisp.h (enum pvec_type): Avoid explicit enum member values.
987 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
988 PVEC_TYPE_MASK to arrange new bitfield in the vector header.

990 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
991 information from the vector header. Adjust comment.

1001 (enum mem_type): Adjust comment.
1002 (NEXT_IN_FREE_LIST): New macro.
1003 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
1004 (Fmake_bool_vector): Likewise.
1005 (struct large_vector): New type to represent allocation unit for
1006 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
1007 (large_vectors): Change type to struct large_vector.
1008 (allocate_vector_from_block): Simplify.
1009 (PSEUDOVECTOR_NBYTES): Replace with...
1010 (vector_nbytes): ...new function. Adjust users.
1011 (sweep_vectors): Adjust processing of large vectors.
1012 (allocate_vectorlike): Likewise.
1013 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
1014 Add easserts. Adjust XSETPVECTYPESIZE usage.
1015 (allocate_buffer): Use BUFFER_PVEC_INIT.
1016 (live_vector_p): Adjust to match large vector.
1017 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
1018 * buffer.h (struct buffer): Add next member.
1019 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
1021 (FOR_EACH_BUFFER): Adjust to match struct buffer change.

1027 (xvecsize): New command.
1029 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
1031 * keyboard.c (event_to_kboard): Do not dereference
1032 frame_or_window field of SELECTION_REQUEST_EVENT
1033 and SELECTION_CLEAR_EVENT events (Bug#12814).
1034 * xterm.h (struct selection_input_event): Adjust comment.
1036 2012-11-07 Eli Zaretskii <eliz@gnu.org>
1038 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
1039 such as Scroll Lock, if the respective keys are treated as
1040 function keys, not as modifiers. This avoids destroying non-ASCII
1041 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
1043 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
1045 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
1047 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1049 Restore some duplicate definitions (Bug#12814).
1050 This undoes part of the 2012-11-03 changes. Some people build
1051 with plain -g rather than with -g3, and they need the duplicate
1052 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
1053 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
1054 Define as macros, as well as as enums or as constants.
1056 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
1058 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
1059 to keypad keys (Bug#12816).
1061 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1063 Minor adjustments of recently-changed frame functions.
1064 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
1065 known to be a frame (we're in the FRAMEP branch).
1066 * lisp.h (Qframep): Remove decl. frame.h declares this.
1067 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
1068 since they're meant for Lisp fixnum values.
1070 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1072 * window.c (Fwindow_combination_limit): Revert to the only
1073 required argument and adjust docstring as suggested in
1074 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
1075 by Martin Rudalics <rudalics@gmx.at>.
1077 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1079 Widely used frame validity and checking functions.
1080 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
1081 * frame.c (decode_live_frame, decode_any_frame): New functions.
1082 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
1083 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
1084 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
1085 (Fframe_pointer_visible_p): Use decode_any_frame.

1087 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
1088 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
1089 (Fframe_focus): Likewise. Allow zero number of arguments.
1091 (frame_buffer_list, frame_buffer_predicate): Remove.
1092 * lisp.h (frame_buffer_predicate): Remove prototype.
1093 * buffer.c (Fother_buffer): Use decode_any_frame.
1094 * xdisp.c (Ftool_bar_lines_needed): Likewise.
1095 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
1096 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
1097 (Fclose_font, Ffont_info): Use decode_live_frame.
1098 * fontset.c (check_fontset_name): Likewise.
1099 * terminal.c (Fframe_terminal): Likewise.
1100 * w32fns.c (check_x_frame): Likewise.
1101 * window.c (Fminibuffer_window, Fwindow_at)
1102 (Fcurrent_window_configuration): Likewise.
1103 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
1104 Likewise. Allow zero number of arguments. Adjust docstring.
1105 * dispnew.c (Fredraw_frame): Likewise.
1106 * xfaces.c (frame_or_selected_frame): Remove.
1107 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
1108 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
1109 (Fframe_face_alist): Use decode_live_frame.
1110 * xfns.c (check_x_frame): Likewise.
1112 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1114 * window.c (quad): New function.
1115 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
1116 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
1117 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
1118 (Fwindow_line_height): Use it.
1119 (Fwindow_fringes): Use list3.
1120 (Fwindow_scroll_bars): Use list4.
1121 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
1122 (Fwindow_combination_limit): Allow zero number of arguments.
1124 2012-11-05 Eli Zaretskii <eliz@gnu.org>
1126 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
1128 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
1129 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
1130 file descriptor 2 for standard error. (Bug#12805)
1132 2012-11-05 Chong Yidong <cyd@gnu.org>
1134 * process.c (wait_reading_process_output): Revert previous change.
1136 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
1138 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
1139 This removes code that has been obsolete since around 1990.
1140 * callproc.c (Fcall_process):
1142 * process.c (create_process):
1143 * term.c (dissociate_if_controlling_tty):
1144 Assume setsid exists.
1145 * callproc.c (child_setup): Assume setpgid exists and behaves as
1146 per POSIX.1-1988 or later.
1147 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
1148 * emacs.c (shut_down_emacs):
1149 * sysdep.c (sys_suspend, init_foreground_group):
1150 Assume getpgrp behaves as per POSIX.1-1998 or later.
1151 * msdos.c (setpgrp): Remove.
1152 (tcgetpgrp, setpgid, setsid): New functions.
1153 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
1154 * term.c (no_controlling_tty): Remove; unused.
1155 * w32proc.c (setpgrp): Remove.
1156 (setsid, tcgetpgrp): New functions.
1158 Simplify by assuming __fpending.
1159 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
1160 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
1161 Do not assume that __fpending's result fits in int.
1163 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
1165 Remove EMACS_OUTQSIZE+sleep hack.
1166 * dispnew.c (update_frame_1): Remove hack for terminals slower
1167 than 2400 bps, which throttled Emacs by having it sleep.
1168 This code hasn't worked since at least 2007, when the multi-tty stuff
1169 was added, and anyway those old terminals are long dead.
1170 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
1171 without the dispnew.c change, as dispnew.c doesn't include systty.h.
1173 Fix data-loss with --version (Bug#9574).
1174 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
1175 as we can't assume that emacs_strerror is initialized, and strerror
1176 is good enough here.
1177 (main): Invoke atexit earlier, to catch earlier instances of
1178 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
1180 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
1182 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
1183 (keyDown): Remap keypad keys to X11 virtual key codes.
1185 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
1187 Fix data-loss with --batch (Bug#9574).
1188 * emacs.c: Include <close-stream.h>.
1189 (close_output_streams): New function.
1190 (main): Pass it to atexit, so that Emacs closes stdout and stderr
1191 and handles errors appropriately.
1192 (Fkill_emacs): Don't worry about flushing, as close_output_stream
1195 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
1196 The symptom is a diagnostic "GLib-WARNING **: In call to
1197 g_spawn_sync(), exit status of a child process was requested but
1198 SIGCHLD action was set to SIG_IGN and ECHILD was received by
1199 waitpid(), so exit status can't be returned." The diagnostic
1200 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
1201 The real bug is a race condition between Emacs and glib: Emacs
1202 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
1203 so that glib can't find it. Work around the bug by invoking
1204 waitpid only on subprocesses that Emacs itself creates.
1205 * process.c (create_process, record_child_status_change):
1206 Don't use special value -1 in pid field, as the caller now must
1207 know the pid rather than having the callee infer it.
1208 The inference was sometimes incorrect anyway, due to another race.
1209 (create_process): Set new 'alive' member if child is created.
1210 (process_status_retrieved): New function.
1211 (record_child_status_change): Use it.
1212 Accept negative 1st argument, which means to wait for the
1213 processes that Emacs already knows about. Move special-case code
1214 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
1215 processes that have already been waited for, by testing and
1216 clearing new 'alive' member.
1217 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
1218 now does this internally.
1219 (handle_child_signal): Let record_child_status_change do all
1220 the work, since we do not want to reap all exited child processes,
1221 only the child processes that Emacs itself created.
1222 * process.h (Lisp_Process): New boolean member 'alive'.
1224 Omit duplicate definitions no longer needed with gcc -g3.
1225 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
1226 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
1227 Define only as macros. There's no longer any need to also define
1228 these symbols as enums or as constants, since we now assume
1229 gcc -g3 when debugging.
1231 2012-11-03 Eli Zaretskii <eliz@gnu.org>
1233 * lisp.mk: Adjust comments to the fact that term/internal is now
1234 loaded from loadup.el.
1236 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
1237 (msdos_fatal_signal): New function.
1238 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
1241 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
1242 for GCC versions before 4.
1243 (emacs_raise): Define to call msdos_fatal_signal.
1245 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
1246 iterator when starting in the middle of a display or overlay
1249 2012-11-03 Chong Yidong <cyd@gnu.org>
1251 * process.c (wait_reading_process_output): Clean up the last
1254 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
1256 * process.c (wait_reading_process_output): Avoid a race condition
1257 with SIGIO delivery (Bug#11536).
1259 2012-11-03 Chong Yidong <cyd@gnu.org>
1261 * buffer.c (cursor_type): Untabify docstring.
1263 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1265 * frame.h (struct frame): Drop can_have_scroll_bars member
1266 which is meaningless for a long time. Adjust comments.
1267 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
1268 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
1270 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
1272 * window.c (decode_next_window_args): Update window arg after
1273 calling decode_live_window and so fix crash reported at
1274 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
1275 by Juanma Barranquero <lekktu@gmail.com>.
1276 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
1277 * font.c (Ffont_at): Likewise.
1279 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
1281 * widget.c (resize_cb): New function.
1282 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
1283 (EmacsFrameResize): Check if all is up to date before changing frame
1286 2012-11-02 Eli Zaretskii <eliz@gnu.org>
1288 Implement backtrace output for fatal errors on MS-Windows.
1289 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
1290 (BACKTRACE_LIMIT_MAX): New macro.
1291 (w32_backtrace): New function.
1292 (emacs_abort): Use w32_backtrace when the user chooses not to
1293 attach a debugger. Update the text of the abort dialog.
1295 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1297 Window-related stuff cleanup here and there.
1298 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
1299 Use decode_any_window.
1300 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
1301 * xdisp.c (Fformat_mode_line): Likewise.
1302 * font.c (Ffont_at): Use decode_live_window.
1303 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
1304 * window.c (decode_next_window_args): Likewise.
1305 (decode_any_window): Remove static.
1306 * window.h (decode_any_window): Add prototype.
1307 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
1308 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
1311 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
1313 Remove pad from struct input_event.
1314 * termhooks.h (struct input_event): Remove padding field.
1316 * keyboard.c (event_to_kboard): Simplify because frame_or_window
1317 member is never cons for a long time. Adjust comment.
1318 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
1319 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
1320 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
1321 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
1323 2012-11-01 Eli Zaretskii <eliz@gnu.org>
1325 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
1327 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
1329 Fix crash when using Emacs as commit editor for git (Bug#12697).
1330 * callproc.c (setpgrp): Remove macro, as we now use setpgid
1331 and it is configured in conf_post.h.
1332 (Fcall_process): Don't invoke both setsid and setpgid; the former
1333 is enough, if it exists.
1334 * callproc.c (Fcall_process, child_setup):
1335 * process.c (create_process): Use setpgid.
1336 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
1338 * dispnew.c (init_display): Initialize the foreground group
1339 if we are running a tty display.
1340 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
1341 * lisp.h (init_foreground_group): New decl.
1342 * sysdep.c (inherited_pgroup): New static var.
1343 (init_foreground_group, tcsetpgrp_without_stopping)
1344 (narrow_foreground_group, widen_foreground_group): New functions.
1345 (init_sys_modes): Narrow foreground group.
1346 (reset_sys_modes): Widen foreground group.
1348 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
1350 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
1352 2012-10-31 Martin Rudalics <rudalics@gmx.at>
1354 * minibuf.c (read_minibuf): Restore current buffer since
1355 choose_minibuf_frame calling Fset_frame_selected_window may
1356 change it (Bug#12766).
1358 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
1360 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
1362 2012-10-30 Kenichi Handa <handa@gnu.org>
1364 * font.c (Ffont_at): If WINDOW is specified and it is not
1365 displaying the current buffer, signal an error.
1367 2012-10-29 Daniel Colascione <dancol@dancol.org>
1369 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
1370 In preparation for fixing bug#12739, move these functions from
1373 * coding.h, coding.c: ... to here, and compile them only when
1374 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
1375 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
1377 2012-10-28 Eli Zaretskii <eliz@gnu.org>
1379 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
1380 (timer_loop, getitimer, setitimer): Use it instead of
1381 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
1383 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
1386 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
1388 * nsterm.m (NO_APPDEFINED_DATA): New define.
1389 (last_appdefined_event_data): New variable
1390 (last_appdefined_event): Remove.
1391 (ns_select): Initialize t from last_appdefined_event_data instead
1392 of [last_appdefined_event data1].
1393 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,

1398 * frame.c (x_set_font): Catch internal error.
1400 2012-10-27 Eli Zaretskii <eliz@gnu.org>
1402 Avoid overflow in w32 implementation of interval timers.
1403 When possible, for ITIMER_PROF count only times the main thread
1405 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
1406 'volatile ULONGLONG' types. All the other data which was
1407 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
1408 (GetThreadTimes_Proc): New typedef.
1409 (w32_get_timer_time): New function, returns a suitable time value
1411 (timer_loop): Enter critical section when accessing ULONGLONG
1412 values of the itimer_data struct, as these accesses are no longer
1413 atomic. Call 'w32_get_timer_time' instead of 'clock'.
1414 Remove unused variable.
1415 (init_timers): Initialize s_pfn_Get_Thread_Times.
1416 (start_timer_thread): Don't assign itimer->caller_thread here.
1417 (getitimer): Assign itimer->caller_thread here.

1423 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
1424 mouse movement events if the menu bar is active. This avoids
1425 producing a busy "hour-glass" cursor by Windows if the mouse
1426 pointer is positioned over a tooltip shown for some menu item.
1428 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
1430 Don't assume process IDs fit in int.
1431 * emacs.c (shut_down_emacs) [!DOS_NT]:
1432 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
1433 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
1434 Use pid_t, not int, to store process IDs, as 'int'
1435 is not wide enough on a few platforms (e.g., AIX and IRIX).
1437 2012-10-23 Kenichi Handa <handa@gnu.org>
1439 The following change is to make face-font-rescale-alist work
1440 correctly for non-ASCII fonts.

1462 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
1464 Port to OpenBSD 5.1.
1465 * frame.c (Fmouse_position, Fmouse_pixel_position):
1466 * xdisp.c (produce_stretch_glyph):
1467 Declare local vars only when they're needed.
1468 This is clearer and avoids a warning on OpenBSD about unused vars.

1470 This is safer, and avoids OpenBSD warnings about unused vars.
1471 * keyboard.c (record_menu_key): Remove unnecessary decl.
1472 (poll_timer): Define only if POLL_FOR_INPUT is defined.
1473 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
1474 as our definition clashes with OpenBSD's.
1475 * xfaces.c (load_face_colors, check_lface_attrs)
1476 (get_lface_attributes_no_remap, get_lface_attributes)
1477 (lface_fully_specified_p, x_supports_face_attributes_p)
1478 (tty_supports_face_attributes_p, face_fontset, realize_face)
1479 (realize_x_face, realize_tty_face):
1480 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
1481 merely Lisp_Object *. This is more informative and avoids
1482 a warning on OpenBSD about accessing beyond an object's size.
1484 2012-10-20 Chong Yidong <cyd@gnu.org>
1486 * lread.c (Fload): Doc fix (Bug#12592).

1512 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
1513 (staticpro): If we run out of staticpro slots, die with an
1514 informative error instead of just calling emacs_abort.
1516 2012-10-18 Martin Rudalics <rudalics@gmx.at>
1518 Fix two flaws reported by Dmitry Antipov.

1776 the same pointer-to-int (now pointer-to-boolean) &input_pending,

1829 2012-10-08 Daniel Colascione <dancol@dancol.org>
1831 * xdisp.c (start_hourglass): Call w32_note_current_window when

1833 build that caused Emacs to display the hourglass cursor forever.
1835 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
1836 which is broken under remote desktop, calculate the number of
1837 colors available for a display based on the display's number of

1873 (x_to_w32_color): Don't modify the argument, modify a copy instead.
1875 2012-10-08 Daniel Colascione <dancol@dancol.org>
1877 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
1878 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
1879 accidental message numbering hole. Change other messages to
1882 * w32select.h (HAVE_W32SELECT): Remove.
1884 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
1885 w32common.h instead of w32heap.h.
1887 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
1888 (get_allocation_unit, get_processor_type, get_w32_major_version)
1889 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
1890 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
1891 (OS_NT, os_subtype, cache_system_info): Move declarations to
1894 * w32heap.c: Include w32common.h.
1895 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
1896 (w32_minor_version, w32_build_number, w32_subtype):
1897 Remove duplicate definitions.
1899 * w32fns.c: Include w32common.h; include w32heap.h only in
1902 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
1903 Use `report_file_error' instead of `error' in order to better
1904 inform users of what went wrong. Increase NTGUI_UNICODE file
1905 dialog box file name length to 32k, the maximum allowed by the NT
1908 * w32common.h: New file.
1909 (ROUND_UP, ROUND_DOWN, get_page_size)
1910 (get_allocation_unit, get_processor_type, get_w32_major_version)
1911 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
1912 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
1913 (OS_NT, os_subtype, cache_system_info): Move here.
1915 * unexw32.c, unexcw.c: Include w32common.h.
1917 * emacs.c (main): Use (defined (WINDOWSNT) || defined
1918 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
1919 to call syms_of_w32select.
1921 * cygw32.h: Remove obsolete EXFUN declarations.
1923 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
1925 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
1926 of w32inevt.o from SOME_MACHINE_OBJECTS.
1928 2012-10-08 Daniel Colascione <dancol@dancol.org>
1930 * image.c: Permanent fix for JPEG compilation issue --- limit
1931 jpeglib `boolean' redefinition to Cygwin builds.
1933 2012-10-08 Eli Zaretskii <eliz@gnu.org>
1935 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
1937 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
1940 2012-10-08 Daniel Colascione <dancol@dancol.org>
1942 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
1943 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
1944 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
1945 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
1946 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
1947 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
1948 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
1949 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
1950 now a supported configuration.
1952 * Makefile.in: consolidate image variables into LIBIMAGE; add
1953 W32_OBJ and W32_LIBS. Compile new files.
1956 (_DebPrint) declare tracing facility for W32 debugging. We need
1957 to unify tracing later.
1959 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
1960 unconditional use of W32 Unicode functions. Cygwin runs only on
1961 100% Unicode operating systems.
1963 * cygw32.c: New file. Define Cygwin-specific facilities.
1964 (Fcygwin_convert_path_to_windows)
1965 (Fcygwin_convert_path_from_windows): New user functions for
1966 accessing Cygwin path-munging routines.
1968 * cygw32.h: New file.
1969 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
1970 UTF-16LE strings temporarily inside non-Lisp-visible string
1973 (w32_strerror): Just what it says on the tin.
1975 * emacs.c: Make the NS fork-then-exec code for daemon-launching
1976 also run for Cygwin; both systems have the same problem with using
1977 GUI facilities in a forked child. Also call syms_of_cygw32,
1978 syms_of_w32select in correct places.
1980 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
1981 needs fork-then-exec for daemon launching.
1983 * font.h: Include frame.h.
1985 * image.c: Use the image library cache machinery only when we're
1986 compiling for native WINDOWSNT; Cygwin can use shared libraries
1987 like any other Unixlike system.
1989 * keyboard.c: Clarify a comment regarding the input loop.
1991 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
1992 functions directly instead of trying to detect at runtime that our
1993 host operating system supports them. We make this change for two
1994 reasons: Cygwin lacks support for the multibyte character
1995 conversion functions used by the legacy menu code, and Cygwin
1996 never needs to rely on non-Unicode APIs.
1998 * unexw32.c (hinst): Declare extern.
2000 * w32.c: Change header order;
2001 (w32_strerror): Move to w32fns.c because we need it for
2002 non-WINDOWSNT builds.
2004 * w32.h: Add #error macro to make sure we don't include w32.h for
2005 Cygwin builds. Remove w32select declarations.
2007 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
2008 w32fns.c. w32console.c is WINDOWSNT-only.
2010 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
2011 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
2013 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
2014 (w32_major_version, w32_minor_version, w32_build_number)
2015 (os_subtype, sound_type): Define here
2016 (w32_defined_color): Make color parameter const for consistency
2017 with other _defined_color functions.
2018 (w32_createwindow): Unconditionally call w32_init_class instead of
2019 doing so only when hprevinst is non-NULL. Plumbing hprevinst
2020 through the code is complex and unnecessary because class
2021 registration is practically free.
2022 (w32_name_of_message): New EMACSDEBUG-only function.
2023 (Fset_message_beep): Move here
2024 (Fx_open_connection): Require that the display name for Windows be
2025 "w32" for consistency, emacsclient disambiguation, and maybe, one
2026 day, multi-window-system support.
2027 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
2028 Cygwin files for W32 GUI facilities, since these clearly don't
2029 expect Cygwin names.
2030 (_DebPrint): Define.
2031 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
2032 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
2033 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
2034 (w32_last_error): Remove.
2036 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
2038 * w32heap.c (syspage_mask): Declare here.
2039 (cache_system_info): Remove.
2041 * w32inevt.c (faked_key): Define globally, not statically.
2042 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
2043 (w32_console_toggle_lock_key): Move to w32fns.c.
2045 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
2047 * w32proc.c (_DebPrint): Move to w32fns.c.
2048 * w32select.c: Include string.h, stdio.h for Cygwin.
2049 * w32select.h: New File.
2051 * w32term.c: Include io.h for non-CYGWIN builds; needed for
2053 (w32_message_fd): New variable. Under Cygwin, holds the file
2054 descriptor the system used to tell us about pending thread
2057 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
2058 that prevented compilation under non-WINDOWSNT systems.
2060 (w32_initialize): Open /dev/windows and assign it to
2061 w32_message_fd. Provide w32 feature.
2063 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
2064 (WM_EMACS_INPUT_READY): add.
2065 (prepend_msg, w32_message_fd): Declare globally.
2068 (keyboard_handle): Use only when WINDOWSNT.
2069 (notify_msg_ready): New function. Posts a message to the main
2070 thread's message queue under CYGWIN, which wakes up the main
2071 thread from select(2) by making the /dev/windows file descriptor
2072 ready. Under WINDOWSNT, it sets an event the same way the old
2075 (post, prepend_msg): Actually call notify_msg_ready instead of
2076 setting the input event directly.
2078 2012-10-07 Eli Zaretskii <eliz@gnu.org>
2080 * ralloc.c (relinquish): If a heap is ready to be relinquished,
2081 but it still has blocs in it, don't return it to the system,
2082 instead of aborting. (Bug#12402)
2084 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
2086 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
2088 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
2089 MAC_OS_X_VERSION_10_6.
2090 (syms_of_nsterm): Remove comment about Panther and above for
2092 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
2093 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
2094 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
2096 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
2097 MAC_OS_X_VERSION_10_4.
2099 * nsmenu.m (fillWithWidgetValue:): Remove code for <
2100 MAC_OS_X_VERSION_10_2.
2102 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
2104 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
2105 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
2107 * nsterm.m (ns_in_resize): Remove (Bug#12479).
2108 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
2109 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
2110 Remove ns_in_resize check.
2111 (ns_clear_frame_area): Remove resize handle code.
2113 * nsfns.m (ns_in_resize): Remove.
2114 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
2115 Remove ns_in_resize check.
2117 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
2119 Improve sys_siglist detection.
2120 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
2121 defined as a macro, as is done in Solaris.
2122 (sys_siglist_entries): New macro.
2123 (save_strsignal): Use it.
2124 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
2125 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
2127 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
2129 * nsfns.m (Fx_create_frame): Call x_default_parameter with
2130 fullscreen/Fullscreen.
2132 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
2133 tobar_height is new.
2135 * nsterm.m (x_make_frame_visible): Check for fullscreen.
2136 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
2137 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
2138 (windowDidResize:): Check for correct window if old style fullscreen.
2139 Capitalize word in comment. Remove incorrect comment.
2140 (initFrameFromEmacs:): tbar_height renamed tibar_height.
2141 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
2142 error in drawing background.
2143 (toggleFullScreen:): Remove comment. Rearrange calls.
2144 Set toolbar values to zero, save old height in tobar_height.
2145 Restore tool bar height when leaving fullscreen.
2146 (canBecomeMainWindow): New function.
2148 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
2150 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
2152 2012-10-05 Eli Zaretskii <eliz@gnu.org>
2154 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
2156 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
2157 that time stamps of directories could also be changed.
2158 Don't request the too broad GENERIC_WRITE, only the more restrictive
2159 FILE_WRITE_ATTRIBUTES access rights.
2161 * fileio.c (Fset_file_times): Special-case ignoring errors for
2162 directories only on MSDOS, not on MS-Windows.
2164 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
2166 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
2168 2012-10-04 Eli Zaretskii <eliz@gnu.org>
2170 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
2171 see whether CreateFile failed.
2173 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
2175 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
2176 to avoid similar races.
2177 * keyboard.c (pending_signals): Now bool, not int.
2179 Port timers to OpenBSD, plus check for timer failures.
2180 OpenBSD problem reported by Han Boetes.
2181 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
2183 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
2184 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
2185 like OpenBSD, which has timer_settime but does not declare it.
2186 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
2187 whether to use itimerspec-related primitives. All uses of
2188 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
2190 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2192 * profiler.c (handle_profiler_signal): Fix a malloc race
2193 that caused Emacs to hang on Fedora 17 when profiling Lisp.
2195 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
2197 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
2199 2012-10-02 Eli Zaretskii <eliz@gnu.org>
2201 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
2202 consistent with the change in return value of 'safe_strsignal'.
2204 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2206 Prefer plain 'static' to 'static inline' (Bug#12541).
2207 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
2208 (bidi_set_sor_type, bidi_push_embedding_level)
2209 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
2210 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
2211 (bidi_cache_search, bidi_cache_ensure_space)
2212 (bidi_cache_iterator_state, bidi_cache_find)
2213 (bidi_peek_at_next_level, bidi_set_paragraph_end)
2214 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
2215 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
2216 Now 'static', not 'static inline'.
2218 Count overruns when profiling; change units to ns.
2219 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
2220 Give extra weight to samples after overruns, to attempt to count
2221 the time more accurately.
2222 (setup_cpu_timer): Change sampling interval units from ms to ns, since
2223 the underlying primitives nominally do ns.
2224 (Fprofiler_cpu_start): Document the change. Mention that
2225 the sampling intervals are only approximate.
2227 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
2229 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
2231 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
2232 case for the special 0 coding-system.
2234 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
2235 (Fmake_overlay): Remove redundant tests.
2236 (fix_start_end_in_overlays): Remove redundant recentering.
2238 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
2240 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
2241 Update dependencies.
2243 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2245 Fix a malloc race condition involving strsignal.
2246 A signal can arrive in the middle of a malloc, and Emacs's signal
2247 handler can invoke strsignal, which can invoke malloc, which is
2248 not portable. This race condition bug makes Emacs hang on GNU/Linux.
2249 Fix it by altering the signal handler so that it does not invoke
2251 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
2252 * process.c (status_message): Use const pointer, in case strsignal
2253 is #defined to safe_strsignal.
2254 * sysdep.c (sys_siglist, init_signals): Always define and
2255 initialize a substitute sys_siglist if the system does not define
2256 one, even if HAVE_STRSIGNAL.
2257 (safe_strsignal): Rename from strsignal. Always define,
2258 using sys_siglist. Return a const pointer.
2259 * syssignal.h (safe_strsignal): New decl.
2260 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
2262 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2264 * w32proc.c (timer_loop): Fix code that waits for timer
2265 expiration, to avoid high CPU usage.
2267 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
2269 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
2270 (sweep_weak_table): Remove redundant prototypes.
2272 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
2274 * emacs.c: Move the inclusion of TERM_HEADER after including
2275 windows.h on WINDOWSNT. This avoids compilation problems with
2278 2012-10-01 Eli Zaretskii <eliz@gnu.org>
2280 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
2281 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
2282 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
2283 as the previous version used 'void *'.
2285 * ralloc.c (ROUNDUP): Fix last change.
2286 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
2289 * w32proc.c <disable_itimers>: New static flag.
2290 (init_timers): Initialize it to zero, after creating the critical
2291 sections used by the timer threads.
2292 (term_timers): Set to 1 before deleting the critical sections.
2293 (getitimer, setitimer): If disable_itimers is non-zero, return an
2294 error indication without doing anything. Reported by Fabrice
2295 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
2296 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
2298 [!HAVE_SETITIMER]: Behave as the previous version that didn't
2301 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
2302 term_ntproc after all the other bookkeeping, to get timers working
2303 as long as possible.
2305 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2307 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
2308 Suggested by Juri Linkov in
2309 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
2311 Prefer plain 'static' to 'static inline' (Bug#12541).
2312 With static functions, modern compilers inline pretty well by
2313 themselves; advice from programmers often hurts as much as it helps.
2314 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
2315 this change shrinks the text size of the Emacs executable by 1.1%
2316 without affecting CPU significantly in my benchmark.
2317 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)
2318 (live_float_p, live_misc_p, live_vector_p, live_buffer_p)
2319 (mark_maybe_object, mark_maybe_pointer, bounded_number):
2320 * buffer.c (bset_abbrev_mode, bset_abbrev_table)
2321 (bset_auto_fill_function, bset_auto_save_file_format)
2322 (bset_auto_save_file_name, bset_backed_up, bset_begv_marker)

2615 for consistency with other handlers.
2616 (setup_cpu_timer): New function, with much of what used to be in

2618 Prefer timer_settime if available, and prefer
2619 thread cputime clocks, then process cputime clocks, then
2620 monotonic clocks, to the old realtime clock. Use make_timeval
2621 to round more-correctly when falling back to setitimer.
2622 (Fprofiler_cpu_start): Use it.
2623 (Fprofiler_cpu_stop): Prefer timer_settime if available.

2689 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
2690 Since this stuff is now private to charset.c, there's no need for
2691 a public macro and no need to inline by hand.

2801 now return bool, not int. All uses changed.
2802 * image.c: Omit unnecessary static decls.
2803 (x_create_bitmap_mask, x_build_heuristic_mask):
2804 Return void, not int, since callers don't care about the return value.

2839 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
2841 Move pid_t related decls out of lisp.h.
2842 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
2843 (interruptible_wait_for_termination):
2844 Move these decls from lisp.h to syswait.h, since they use pid_t.
2845 Needed on FreeBSD; see Herbert J. Skuhra in
2846 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
2847 * callproc.c: Include syswait.h.

2867 Use bool for boolean.
2868 * gtkutil.c (xg_update_frame_menubar):

2893 2012-09-23 Eli Zaretskii <eliz@gnu.org>
2895 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
2896 fatal_error_backtrace.
2898 * w32proc.c (sys_kill): Undo last change: don't do anything when
2899 invoked to deliver SIGABRT to our own process. This is now
2900 handled by emacs_raise.
2902 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
2904 * w32term.c (w32_read_socket): Remove leftover reference to
2905 interrupt_input_pending.
2907 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
2909 Do not use SA_NODEFER.
2910 Problem reported by Dani Moncayo in
2911 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
2913 * sysdep.c (emacs_abort): Do not reset signal handler.
2914 * emacs.c (terminate_due_to_signal): Reset signal handler here.
2915 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
2916 wanted even on POSIXish hosts, and it doesn't work on Windows.
2918 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
2920 * xterm.c (x_term_init): Call fixup_locale before and after calling
2921 gtk_init (Bug#12392).
2923 2012-09-23 Chong Yidong <cyd@gnu.org>
2925 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
2926 Vdynamic_library_alist.
2928 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
2929 (Fgnutls_available_p): Caller changed.
2931 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
2932 (Flibxml_parse_xml_region): Likewise.
2934 * dispextern.h (struct image_type): Remove arg from init function.
2936 * image.c (Finit_image_library, lookup_image_type)
2937 (define_image_type): Remove now-unneeded second arg.
2938 (init_xpm_functions, init_png_functions, init_jpeg_functions)
2939 (init_tiff_functions, init_gif_functions, init_svg_functions):
2940 Arglist and w32_delayed_load calling convention changed.
2941 (gs_type): Remove init_gs_functions; there is no such function.
2942 (valid_image_p, make_image): Fix caller to lookup_image_type.
2944 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
2946 Simplify and avoid signal-handling races (Bug#12471).
2948 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
2949 Avoid recursive loop if there's a fatal error in the function itself.
2950 * atimer.c (pending_atimers):
2951 * blockinput.h: Don't include "atimer.h"; no longer needed.
2952 (interrupt_input_pending): Remove. All uses removed.
2953 pending_signals now counts both atimers and ordinary interrupts.
2954 This is less racy than having three separate pending-signal flags.
2955 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
2957 Rename from their upper-case counterparts BLOCK_INPUT,
2958 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
2959 INPUT_BLOCKED_P, and turn into functions. All uses changed.
2960 This makes it easier to access volatile variables more accurately.
2961 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
2962 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
2963 that's more reliable if the code is buggy and sets
2964 interrupt_input_blocked to a negative value. All uses changed.
2965 * atimer.c (deliver_alarm_signal):
2966 Remove. No need to deliver this to the parent; any thread can
2967 handle this signal now. All uses replaced by underlying handler.
2968 * atimer.c (turn_on_atimers):
2969 * dispnew.c (handle_window_change_signal):
2970 * emacs.c (handle_danger_signal):
2971 * keyboard.c (kbd_buffer_get_event):
2972 Don't reestablish signal handler; not needed with sigaction.
2973 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
2975 Rework to avoid unnecessary accesses to volatile variables.
2976 (UNBLOCK_INPUT_TO): Now a function.
2977 (totally_unblock_input, unblock_input): New decls.
2978 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
2979 (init_data): Remove. Necessary stuff now done in init_signal.
2980 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
2981 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
2982 (fatal_error_code): Remove; no longer needed.
2983 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
2984 it doesn't always backtrace. All uses changed. No need to reset
2985 signal to default, since sigaction and/or die does that for us now.
2986 Use emacs_raise (FOO), not kill (getpid (), FOO).
2987 (main): Check more-accurately whether we're dumping.
2988 Move fatal-error setup to sysdep.c
2989 * floatfns.c: Do not include "syssignal.h"; no longer needed.
2990 * gtkutil.c (xg_get_file_name, xg_get_font):
2991 Remove no-longer-needed signal-mask manipulation.
2992 * keyboard.c, process.c (POLL_FOR_INPUT):
2993 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
2994 * keyboard.c (read_avail_input): Remove.
2995 All uses replaced by gobble_input.
2996 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
2997 (kbd_buffer_store_event_hold, gobble_input):
2998 (record_asynch_buffer_change) [USABLE_SIGIO]:
2999 (store_user_signal_events):
3000 No need to mess with signal mask.
3001 (gobble_input): If blocking input and there are terminals, simply
3002 set pending_signals to 1 and return. All hooks changed to not
3003 worry about whether input is blocked.
3004 (process_pending_signals): Clear pending_signals before processing
3005 them, in case a signal comes in while we're processing.
3006 By convention callers now test pending_signals before calling us.
3007 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
3008 New functions, to support changes to blockinput.h.
3009 (handle_input_available_signal): Now extern.
3010 (reinvoke_input_signal): Remove. All uses replaced by
3012 (quit_count): Now volatile, since a signal handler uses it.
3013 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
3014 All callers changed. Block SIGINT only if not already blocked.
3015 Clear sigmask reliably, even if Fsignal returns, which it can.
3016 Omit unnecessary accesses to volatile var.
3017 (quit_throw_to_read_char): No need to restore sigmask.
3018 * keyboard.c (gobble_input, handle_user_signal):
3019 * process.c (wait_reading_process_output):
3020 Call signal-handling code rather than killing ourselves.
3021 * lisp.h: Include <float.h>, for...
3022 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
3023 (pending_signals): Now volatile.
3024 (syms_of_data): Now const if IEEE floating point.
3025 (handle_input_available_signal) [USABLE_SIGIO]:
3026 (terminate_due_to_signal, record_child_status_change): New decls.
3027 * process.c (create_process): Avoid disaster if memory is exhausted
3028 while we're processing a vfork, by tightening the critical section
3030 (send_process_frame, process_sent_to, handle_pipe_signal)
3031 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
3033 (send_process): No need for setjmp/longjmp any more, since the
3034 SIGPIPE stuff is now gone. Instead, report an error if errno
3036 (record_child_status_change): Now extern. PID and W are now args.
3037 Return void, not bool. All callers changed.
3038 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
3039 Remove. All uses removed. This bug should be fixed now in a
3041 (wait_for_termination_1): Use waitpid rather than sigsuspend,
3042 and record the child status change directly. This avoids the
3043 need to futz with the signal mask.
3044 (process_fatal_action): Move here from emacs.c.
3045 (emacs_sigaction_flags): New function, containing
3046 much of what used to be in emacs_sigaction_init.
3047 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
3048 caught by emacs, to make races less likely.
3049 (deliver_process_signal): Rename from handle_on_main_thread.
3051 (BACKTRACE_LIMIT_MAX): Now at top level.
3052 (thread_backtrace_buffer, threadback_backtrace_pointers):
3054 (deliver_thread_signal, deliver_fatal_thread_signal):
3055 New functions, for more-accurate delivery of thread-specific signals.
3056 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
3057 (deliver_arith_signal): Handle in this thread, not
3058 in the main thread, since it's triggered by this thread.
3059 (maybe_fatal_sig): New function.
3060 (init_signals): New arg DUMPING so that we can be more accurate
3061 about whether we're dumping. Caller changed.
3062 Treat thread-specific signals differently from process-general signals.
3063 Block all signals while handling fatal error; that's safer.
3064 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
3066 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
3067 Ignore SIGPIPE unless batch.
3068 (emacs_backtrace): Output backtrace for the appropriate thread,
3069 which is not necessarily the main thread.
3070 * syssignal.h: Include <stdbool.h>.
3071 (emacs_raise): New macro.
3072 * xterm.c (x_connection_signal): Remove; no longer needed
3073 now that we use sigaction.
3074 (x_connection_closed): No need to mess with sigmask now.
3075 (x_initialize): No need to reset SIGPIPE handler here, since
3076 init_signals does this for us now.
3078 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3080 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
3081 background rect may be larger (Bug#12245).
3083 2012-09-23 Chong Yidong <cyd@gnu.org>
3085 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
3087 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3089 * .gdbinit: Just stop at fatal_error_backtrace.
3090 See Stefan Monnier's request in
3091 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
3092 Remove no-longer-used query of system type.
3094 2012-09-22 Chong Yidong <cyd@gnu.org>
3096 * search.c (Freplace_match): Doc fix (Bug#12325).
3098 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
3100 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
3101 (Fline_end_position): Doc fix.
3103 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
3105 2012-09-22 Chong Yidong <cyd@gnu.org>
3107 * dispextern.h (struct image_type): Add new slot, storing a type
3108 initialization function.
3110 * image.c (define_image_type): Call the image initializer function
3111 if it is defined. Arguments and return value changed.
3112 (valid_image_p, make_image): Callers changed.
3113 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
3114 (gif_type, imagemagick_type, svg_type, gs_type):
3115 Add initialization functions.
3116 (Finit_image_library): Call lookup_image_type.
3117 (CHECK_LIB_AVAILABLE): Macro deleted.
3118 (lookup_image_type): Call define_image_type here, rather than via
3119 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
3120 (syms_of_image): Move define_image_type calls for xbm_type and
3121 pbm_type to lookup_image_type.
3123 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3125 * keyboard.c (timer_check_2): Move calculation of 'timers' and
3126 'idle_timers' from here ...
3127 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
3128 lists, to avoid infloops when the timer does something stupid,
3129 like reinvoke itself with the same or smaller time-out.
3132 2012-09-22 Martin Rudalics <rudalics@gmx.at>
3134 * window.c (Fsplit_window_internal): Handle only Qt value of
3135 Vwindow_combination_limit separately.
3136 (Qtemp_buffer_resize): New symbol.
3137 (Vwindow_combination_limit): New default value.
3140 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3142 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
3143 the new overlay string. (Bug#10159)
3145 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3147 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
3148 or that fprintf is async-signal-safe. POSIX doesn't require
3151 2012-09-22 Chong Yidong <cyd@gnu.org>
3153 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
3156 2012-09-22 Kenichi Handa <handa@gnu.org>
3158 * composite.c (composition_reseat_it): Handle the case that a
3159 grapheme cluster is not covered by a single font (Bug#12352).
3161 2012-09-21 Chong Yidong <cyd@gnu.org>
3163 * image.c (define_image_type): Avoid adding duplicate types to
3164 image_types (Bug#12463). Suggested by Jörg Walter.
3166 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3168 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
3169 (print_load_command_name): Add case LC_DATA_IN_CODE.
3170 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.

3174 * eval.c (Frun_hook_with_args_until_success)
3175 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
3177 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
3179 * fileio.c (Ffile_selinux_context): Only call freecon when
3180 lgetfilecon succeeded.
3181 (Fset_file_selinux_context): Likewise. (Bug#12444)
3183 2012-09-21 Eli Zaretskii <eliz@gnu.org>
3185 * xdisp.c (try_window_reusing_current_matrix): Under bidi
3186 reordering, locate the cursor by calling set_cursor_from_row; if
3187 that fails, clear the desired glyph matrix before returning a
3188 failure indication to the caller. Fixes leaving garbled display
3189 when fast scrolling with a down-key. (Bug#12403)
3190 (compute_stop_pos_backwards): Fix a typo that caused crashes while
3191 scrolling through multibyte text.
3193 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
3195 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
3196 calling mark_vectorlike since that's the one that marks the window.
3197 (mark_discard_killed_buffers): Mark the final cdr.
3198 * window.h (struct window): Move prev/next_buffers to the
3199 non-standard fields.
3200 * window.c (make_window): Initialize prev/next_buffers manually.
3202 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
3204 Omit unused arg EXPECTED from socket hooks.
3205 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
3206 * nsterm.m (ns_term_init):
3207 * termhooks.h (struct terminal.read_socket_hook):
3208 * w32inevt.c (w32_console_read_socket):
3209 * w32term.c (w32_read_socket):
3210 * xterm.c (XTread_socket):
3211 Omit unused arg EXPECTED. All callers changed.
3212 (store_user_signal_events): Return void, not int, since callers no
3213 longer care about the return value. All uses changed.
3215 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
3217 * w32gui.h (XParseGeometry): Do not declare.
3219 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
3221 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
3222 Ignore 'expected'. See Eli Zaretskii in
3223 <http://bugs.gnu.org/12471#8> (last line).
3225 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
3226 (XParseGeometry): Now static. Substitute extremal values for
3227 values that are out of range.
3229 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
3231 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
3233 * nsfns.m (XParseGeometry): Remove.
3234 (Fx_create_frame): Call x_set_offset to correctly interpret
3235 top_pos in geometry.
3237 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
3238 (Fx_parse_geometry): If there is a space in string, call
3239 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
3241 2012-09-17 Eli Zaretskii <eliz@gnu.org>
3243 * search.c (scan_buffer): Use character positions in calls to
3244 region_cache_forward and region_cache_backward, not byte
3245 positions. (Bug#12196)
3247 * w32term.c (w32_read_socket): Set pending_signals to 1, like
3248 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
3250 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
3251 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
3252 emacs_blocked_malloc, now deleted.
3254 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
3256 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
3257 The workaround was for improving performance on Solaris 2.4, but
3258 is getting in the way now. Emacs will still work if someone is
3259 still running Solaris 2.4 in a museum somewhere; Sun dropped
3260 support for Solaris 2.4 in 2003.
3261 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
3262 * process.c (create_process) [HAVE_WORKING_VFORK]:
3263 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
3264 since Emacs no longer uses vfork on that platform.
3266 2012-09-17 Glenn Morris <rgm@gnu.org>
3268 * emacs.c: Use COPYRIGHT.
3270 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
3272 Remove configure's --without-sync-input option (Bug#12450).
3273 When auditing signal-handling in preparation for cleaning it up,
3274 I found that SYNC_INPUT has race conditions and would be a real
3275 pain to fix. Since it's an undocumented and deprecated
3276 configure-time option, now seems like a good time to remove it.
3277 Also see <http://bugs.gnu.org/11080#16>.
3278 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
3279 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
3280 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3281 (malloc_hysteresis):
3282 (check_depth) [XMALLOC_OVERRUN_CHECK]:
3283 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
3284 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)

3286 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
3287 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
3288 [!SYSTEM_MALLOC && !SYNC_INPUT]:
3289 Remove. All uses removed.
3290 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
3291 implementation, one that depends on whether the new macro
3292 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
3294 * atimer.c (run_timers, handle_alarm_signal):
3295 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
3296 (handle_async_input, process_pending_signals)
3297 (handle_input_available_signal, init_keyboard):
3298 * nsterm.m (ns_read_socket):
3299 * process.c (wait_reading_process_output):
3300 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
3301 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
3303 * xterm.c (XTread_socket):
3305 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
3306 * eval.c (handling_signal): Remove. All uses removed.
3307 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
3308 All uses replaced with the SYNC_INPUT version.
3309 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
3311 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3314 * font.c (Ffont_shape_gstring): Remove unused local.
3316 2012-09-16 Glenn Morris <rgm@gnu.org>
3318 * Makefile.in (clean): No longer run nextstep's clean.
3320 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
3322 (ns-app): Move here from ns.mk, and simplify.
3323 (clean): Simplify nextstep entry.
3324 * ns.mk: Remove file.
3326 2012-09-17 Kenichi Handa <handa@gnu.org>
3328 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
3329 not covert the last few charactes.
3331 2012-09-16 Kenichi Handa <handa@gnu.org>
3333 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
3334 here, but just check the validity of glyphs in the glyph-string.
3336 2012-09-16 Martin Rudalics <rudalics@gmx.at>
3338 * window.c (Fwindow_parameter, Fset_window_parameter):
3339 Accept any window as argument (Bug#12452).
3341 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
3343 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
3344 to ns_term_init to avoid memory leak.
3346 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
3347 explicit retain/release.
3348 (ns_term_init): Only allow one display. Initialize outerpool and
3351 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3353 Port _setjmp fix to POSIXish hosts as well as Microsoft.
3354 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
3355 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
3356 the Microsoft problem in a different way, by altering ../nt/config.nt.
3358 2012-09-15 Eli Zaretskii <eliz@gnu.org>
3373 * w16select.c: Remove inclusion of setjmp.h, as it is now included
3374 by lisp.h. This completes removal of setjmp.h inclusion
3375 erroneously announced in the previous commit. (Bug#12446)
3377 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
3380 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
3381 not defined as a macro. The latter happens on MS-Windows.
3384 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
3386 Port better to POSIX hosts lacking _setjmp (Bug#12446).
3387 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
3388 Some instances of '#include <setjmp.h>' removed, if the
3389 only reason for the instance was because "lisp.h" was included.
3390 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
3391 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
3392 and _longjmp with the new symbols. Emacs already uses _setjmp if
3393 available, so this change affects only POSIXish hosts that have
3394 sigsetjmp but not _setjmp, such as some versions of Solaris and
3395 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
3396 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
3397 (png_load_body) [HAVE_PNG]:
3398 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
3399 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
3400 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
3401 since PNG requires jmp_buf. This is the only exception to the
3402 general rule that we now use sys_setjmp and sys_longjmp.
3403 This exception is OK since this code does not change the signal
3404 mask or longjmp out of a signal handler.
3406 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
3408 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
3409 Include "syssignal.h", for 'main_thread'.
3411 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
3413 Avoid out-of-range marker position (Bug#12426).
3414 * insdel.c (replace_range, replace_range_2):
3415 Adjust markers before overlays, as suggested by comments.
3416 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
3417 Remove redundant check before calling offset_intervals.
3419 2012-09-14 Martin Rudalics <rudalics@gmx.at>
3421 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
3422 current buffer (Bug#12387).
3424 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
3426 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
3428 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3430 Use a more backwards-compatible timer format (Bug#12430).
3431 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
3432 vector element, not from the 4th, since PSECS is now at the end.
3433 (Fcurrent_idle_time): Doc fix.
3435 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
3437 Function to mark objects and remove killed buffers at once.
3438 * alloc.c (discard_killed_buffers): Rename to ...
3439 (mark_discard_killed buffers) ... new name. Add marking
3440 of remaining objects. Fix comment. Adjust users.
3441 (mark_object): Do not touch frame buffer lists here.
3442 * frame.c (delete_frame): Reset frame buffer lists here.
3444 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
3446 Better workaround for GNOME bug when --enable-gcc-warnings.
3447 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
3448 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
3449 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
3451 Simplify SIGIO usage (Bug#12408).
3452 The code that dealt with SIGIO was crufty and confusing, e.g., it
3453 played tricks like "#undef SIGIO" but these tricks were not used
3454 consistently. Simplify mostly by not #undeffing standard symbols,
3455 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
3456 or not as we please) rather than "defined SIGIO" (standard symbol
3457 that we probably shouldn't #undef).
3458 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
3459 Modules that need it can include it.
3460 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
3461 * dispextern.h (ignore_sigio): New decl.
3462 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
3463 unconditionally, since it's now a no-op if !USABLE_SIGIO.
3464 * emacs.c (shut_down_emacs):
3465 * keyboard.c (kbd_buffer_store_event_hold):
3466 Use ignore_sigio rather than invoking 'signal' directly.
3467 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
3469 (FIONREAD, SIGIO): Do not #undef.
3470 (tty_read_avail_input): Use #error rather than a syntax error.
3471 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
3472 for I_PIPE, used by SETUP_SLAVE_PTY.
3473 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
3474 * sysdep.c (croak): Remove; no longer needed. This bit of
3475 temporary code, with Fred N. Fish's comment that it's temporary,
3476 has been in Emacs since at least 1992!
3477 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
3478 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
3479 * syssignal.h (croak): Remove decl.
3480 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
3481 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
3482 now that we're termios-only.
3483 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
3484 * term.c (dissociate_if_controlling_tty): Use #error rather than
3487 Work around GCC and GNOME bugs when --enable-gcc-warnings.
3488 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
3489 to work around GNOME bug 683906.
3490 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
3491 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
3492 This works around GCC bug 54561.
3494 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
3496 More fixes for 'volatile' and setjmp/longjmp.
3497 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
3498 * image.c (struct png_load_context) [HAVE_PNG]: New type.
3499 (png_load_body) [HAVE_PNG]:
3500 (jpeg_load_body) [HAVE_JPEG]:
3501 New function, with most of the old parent function's body.
3502 (png_load) [HAVE_PNG]:
3503 (jpeg_load) [HAVE_JPEG]:
3504 Invoke the new function, to avoid longjmp munging our locals.
3505 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
3506 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
3507 longjmp is passed 2, as the C standard doesn't guarantee this.
3508 Instead, store the failure code into mgr->failure_code.
3510 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
3512 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
3513 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
3514 (syms_of_keyboard): Remove support for unread-command-char.
3516 2012-09-12 Eli Zaretskii <eliz@gnu.org>
3518 * w32proc.c (sys_kill): If PID is our process ID and the signal is
3519 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
3520 violation. (Bug#12426)
3522 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
3524 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
3526 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
3528 * eval.c: Add `inhibit-debugger'.
3529 (Qinhibit_debugger): New symbol.
3530 (call_debugger): Bind it instead of Qdebug_on_error.
3531 (maybe_call_debugger): Test Vinhibit_debugger.
3532 (syms_of_eval): Define inhibit-debugger.
3533 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
3534 (syms_of_xdisp): Remove inhibit-debug-on-message.
3536 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
3538 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
3539 If a nonvolatile local variable is written before a _longjmp to
3540 the frame containing the variable, and is read after the _longjmp,
3541 the value read is indeterminate. Some local variables of type
3542 'struct handler' and 'struct catchtag' are used in this way, so
3543 mark each of their slots as volatile if the slot can be set before
3544 _longjmp and read afterwards.
3545 * lisp.h (struct handler): var and chosen_clause are now volatile.
3546 (struct catchtag): val, next, and pdlcount are now volatile.
3548 * bidi.c (bidi_push_it, bidi_pop_it):
3549 * fns.c (copy_hash_table):
3550 * image.c (define_image_type):
3551 * keyboard.c (kbd_buffer_store_event_hold):
3552 * process.c (Fprocess_send_eof):
3553 * xfaces.c (x_create_gc) [HAVE_NS]:
3554 * xgselect.c (xg_select):
3555 Prefer assignment to memcpy when either will do.
3557 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
3558 Use pointer-to-a-pointer to simplify and avoid a NILP check each
3559 time an item is removed. No need to mark this function 'inline';
3560 the compiler knows better than we do.
3562 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
3564 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
3565 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
3566 to change_frame_size (Bug#12388).
3567 (windowDidResize:): Pass YES to updateFrameSize.
3569 * nsterm.h: Add delay parameter to updateFrameSize.
3571 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
3573 Discard killed buffers from deleted window and frame objects.
3574 This reduces an amount of references to killed buffers and
3575 helps GC to reclaim them faster.
3576 * alloc.c (discard_killed_buffers): New function.
3577 (mark_object): Use it for deleted windows and frames.
3578 (mark_object): If symbol's value is set up for a killed buffer
3579 or deleted frame, restore its global binding.
3580 * data.c (swap_in_global_binding): Add GC notice.
3581 (swap_in_symval_forwarding): Use convenient set_blv_where.
3582 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
3583 * window.h: ... to here.
3585 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
3587 Convenient macro to check whether the buffer is live.
3588 * buffer.h (BUFFER_LIVE_P): New macro.
3589 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
3590 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
3592 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3594 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
3595 composition cases (Bug#12364).
3597 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
3598 overhang of succeeding glyphs overlapping box cursor.
3600 * w32term.c (x_draw_glyph_string): Likewise.
3602 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
3604 Simplify, document, and port floating-point (Bug#12381).
3605 The porting part of this patch fixes bugs on non-IEEE platforms
3606 with frexp, ldexp, logb.
3607 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
3609 * floatfns.c: Simplify discussion of functions that Emacs doesn't
3610 support, by removing commented-out code and briefly listing the
3611 C89 functions excluded. The commented-out stuff was confusing
3612 maintenance, e.g., we thought we needed cbrt but it was commented out.
3613 (logb): Remove decl; no longer needed.
3614 (isfinite): New macro, if not already supplied.
3615 (isnan): Don't replace any existing macro.
3616 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
3617 are present on all C89 platforms.
3618 (Ffrexp): Do not special-case zero, as frexp does the right thing
3620 (Flogb): Do not use logb, as it doesn't have the desired meaning
3621 on hosts that use non-base-2 floating point. Instead, stick with
3622 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
3623 frexp, to avoid getting an unspecified result.
3625 * xdisp.c (Qinhibit_debug_on_message): Now static.
3627 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
3629 * nsterm.m (ns_update_begin): Set clip path to whole view by using
3630 NSBezierPath (Bug#12131).
3632 2012-09-10 Chong Yidong <cyd@gnu.org>
3634 * fns.c (Fdelq, Fdelete): Doc fix.
3636 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
3638 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
3639 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
3641 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
3643 * lisp.h (make_lisp_ptr): New macro to replace XSET.
3644 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
3647 2012-09-09 Eli Zaretskii <eliz@gnu.org>
3649 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
3650 left fringe if the window has a left margin. This avoids leaving
3651 traces of the cursor because its leftmost pixel is not drawn over.
3653 * dispnew.c (update_window_line): When the left margin area of a
3654 screen line is updated, set the redraw_fringe_bitmaps_p flag of
3655 that screen line. (Bug#12277)
3657 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
3659 Assume C89 or later for math functions (Bug#12381).
3660 This simplifies the code, and makes it a bit smaller and faster,
3661 and (most important) makes it easier to clean up signal handling
3662 since we can stop worring about floating-point exceptions in
3663 library code. That was a problem before C89, but the problem
3664 went away many years ago on all practical Emacs targets.
3665 * data.c, image.c, lread.c, print.c:
3666 Don't include <math.h>; no longer needed.
3667 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
3668 might be autoconfigured, as that never happens.
3670 * doprnt.c (DBL_MAX_10_EXP):
3671 * print.c (DBL_DIG):
3672 Remove. C89 or later always defines these.
3673 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
3674 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
3675 (arith_error, domain_error, domain_error2):
3676 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
3677 no longer needed -- we simply return what C returns. All uses removed.
3678 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
3680 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
3681 Remove. All uses expanded, as these macros are no longer used
3682 more than once and are now more trouble than they're worth.
3683 (Ftan): Use tan, not sin / cos.
3684 (Flogb): Assume C89 frexp.
3685 (fmod_float): Assume C89 fmod.
3686 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
3687 (init_floatfns): Remove. All uses removed.
3689 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3691 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
3692 compositeToPoint for OSX < 10.6 (Bug#12390).
3694 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
3696 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
3697 This produces more-accurate results.
3699 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3701 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
3702 changes (Bug#12088).
3704 2012-09-08 Chong Yidong <cyd@gnu.org>
3706 * syntax.c (Fstring_to_syntax): Doc fix.
3708 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
3710 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
3711 in the internal border.
3712 (x_set_window_size): Remove static variables and their usage.
3713 (ns_redraw_scroll_bars): Fix NSTRACE arg.
3714 (ns_after_update_window_line, ns_draw_fringe_bitmap):
3715 Remove fringe/internal border adjustment (Bug#11052).
3716 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
3717 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
3718 (ns_fix_rect_ibw): Remove.
3719 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
3720 (ns_dumpglyphs_box_or_relief): Ditto.
3721 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
3723 (ns_dumpglyphs_image): Ditto.
3724 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
3726 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
3727 their usage. Add fringe_extended_p and its use as in other terms.
3728 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
3729 scroll bar was removed.
3730 (updateFrameSize): New function.
3731 (windowDidResize): Move code to updateFrameSize and call it.
3733 * nsterm.h (EmacsView): Add updateFrameSize.
3735 2012-09-07 Chong Yidong <cyd@gnu.org>
3737 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
3739 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
3741 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
3743 More signal-handler cleanup (Bug#12327).
3744 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
3745 Problem introduced when merging patches. Noted by Eli Zaretskii in
3746 <http://bugs.gnu.org/12327#67>.
3747 * floatfns.c: Comment fix.
3748 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
3749 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
3750 and anyway the declaration is harmless even if SIGDANGER is not defined.
3751 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
3752 defined BROKEN_FIONREAD). systty.h formerly did this, but other
3753 source files not surprisingly expected syssignal.h to define, or
3754 not define, SIGIO, and it's cleaner to do it that way, for consistency.
3755 Include <sys/ioctl.h>, for FIONREAD.
3756 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
3757 This eliminates a problem whereby other files mysteriously had
3758 to include "syssignal.h" before including "systty.h" if they
3759 wanted to use "#ifdef SIGIO".
3761 2012-09-07 Eli Zaretskii <eliz@gnu.org>
3763 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
3765 * w32.c (sigemptyset): Empty the set.
3766 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
3768 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
3770 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
3772 * alloc.c (mark_buffer): Revert unsafe marking optimization.
3773 (mark_object): Likewise for frame objects.
3775 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
3777 * syssignal.h (handle_on_main_thread): Always declare,
3778 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
3779 This ports to platforms without HAVE_PTHREAD.
3781 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
3783 Signal-handler cleanup (Bug#12327).
3784 Emacs's signal handlers were written in the old 4.2BSD style with
3785 sigblock and sigmask and so forth, and this led to some
3786 inefficiencies and confusion. Rewrite these to use
3787 pthread_sigmask etc. without copying signal sets around. Also,
3788 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
3789 'signal', and instead use functions that do not attempt to take
3790 over the system name space. This patch causes Emacs's text
3791 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
3792 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
3793 Do not include <signal.h> or "syssignal.h", as these
3794 modules do not use signals.
3795 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
3796 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
3797 Do not include <signal.h>, as "syssignal.h" does that for us now.
3798 * atimer.c (sigmask_atimers): New function.
3799 (block_atimers, unblock_atimers): New functions,
3800 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
3802 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
3803 no longer needed here.
3804 * emacs.c (main): Inspect existing signal handler with sigaction,
3805 so that there's no need to block and unblock SIGHUP.
3806 * sysdep.c (struct save_signal): New member 'action', replacing
3807 old member 'handler'.
3808 (save_signal_handlers, restore_signal_handlers):
3809 Use sigaction instead of 'signal' to save and restore.
3810 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
3811 New function. All users of 'signal' modified to use set_sighandler
3812 if they're writeonly, and to use sys_signal if they're read+write.
3813 (emacs_sigaction_init, forwarded_signal): New functions.
3814 (sys_signal): Remove. All uses replaced by calls to sigaction
3815 and emacs_sigaction_init, or by direct calls to 'signal'.
3816 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
3817 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
3818 all uses replaced by pthread_sigmask etc. calls.
3819 * syssignal.h: Include <signal.h>.
3820 (emacs_sigaction_init, forwarded_signal): New decls.
3821 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
3822 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
3823 (sigmask, sys_sigmask): Remove; no longer needed.
3824 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
3825 (sigblock, sigunblock, sigfree):
3826 (sigsetmask) [!defined sigsetmask]:
3827 Remove. All uses replaced by pthread_sigmask.
3828 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
3829 no longer need to be replaced, and its typical old uses
3830 are now done via emacs_sigaction_init and sigaction.
3831 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
3832 (sys_sigdel): Remove; unused.
3833 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
3835 2012-09-06 Eli Zaretskii <eliz@gnu.org>
3837 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
3838 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
3840 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
3842 Explicitly mark buffer_defaults and buffer_local_symbols.
3843 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
3844 mark_local_symbols here.
3845 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
3846 since special buffers aren't marked here any more.
3847 (allocate_buffer): Chain new buffer with all_buffers here...
3848 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
3850 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
3851 (syms_of_buffer): Remove staticpro of the above.
3852 (init_buffer_once): Set names for buffer_defaults and
3853 buffer_local_symbols.
3855 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
3857 Use bool for booleans in font-related modules.
3858 * font.c (font_intern_prop, font_style_to_value)
3859 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
3860 (generate_otf_features, font_check_otf_features, font_check_otf)
3861 (font_match_p, font_list_entities, font_at):
3862 * fontset.c (fontset_id_valid_p, reorder_font_vector
3863 (fontset_find_font, Fset_fontset_font)
3864 (face_suitable_for_char_p) [0]:
3865 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
3866 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
3867 (m17n_flt_initialized, ftfont_shape_by_flt):
3868 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
3869 * nsfont.m (nsfont_draw):
3870 * w32font.c (w32font_draw):
3871 * w32term.c (x_draw_glyphless_glyph_string_foreground):
3872 Use bool for booleans.
3873 * font.h: Adjust to above API changes.
3874 (struct font, struct font_driver, struct font_driver_list):
3875 Use bool for booleans.
3876 (struct font): Remove useless member encoding_type.
3878 * fontset.c, xftfont.c: Omit unnecessary static decls.
3880 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
3882 * alloc.c (mark_object): Revert window marking code
3883 since it's unsafe for the Fset_window_configuration.
3885 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
3887 Fix race conditions with signal handlers and errno (Bug#12327).
3888 Be more systematic about preserving errno whenever a signal
3889 handler returns, even if it's not in the main thread. Do this by
3890 renaming signal handlers to distinguish between signal delivery
3891 and signal handling. All uses changed.
3892 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
3893 * data.c (deliver_arith_signal): Rename from arith_error.
3894 * dispnew.c (deliver_window_change_signal): Rename from
3895 window_change_signal.
3896 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
3897 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
3898 * keyboard.c (deliver_input_available_signal): Rename from
3899 input_available_signal.
3900 (deliver_user_signal): Rename from handle_user_signal.
3901 (deliver_interrupt_signal): Rename from interrupt_signal.
3902 * process.c (deliver_pipe_signal): Rename from send_process_trap.
3903 (deliver_child_signal): Rename from sigchld_handler.
3904 * atimer.c (handle_alarm_signal):
3905 * data.c (handle_arith_signal):
3906 * dispnew.c (handle_window_change_signal):
3907 * emacs.c (handle_fatal_signal, handle_danger_signal):
3908 * keyboard.c (handle_input_available_signal):
3909 * keyboard.c (handle_user_signal, handle_interrupt_signal):
3910 * process.c (handle_pipe_signal, handle_child_signal):
3911 New functions, with the actual signal-handling code taken from the
3912 original respective signal handlers, sans the sporadic attempts to
3913 preserve errno, since that's now done by handle_on_main_thread.
3914 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
3915 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
3916 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3918 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3919 Move initialization of main_thread to sysdep.c's init_signals.
3920 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
3921 our usage, and simplifies the mainline code.
3922 (record_child_status_change): New static function, as a helper
3923 for handle_child_signal, and with most of the old child handler's
3925 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
3926 (handle_child_signal): Use the above.
3927 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3928 Moved here from emacs.c.
3929 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
3930 code moved here from emacs.c's main function.
3931 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
3932 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
3933 This lets callers save and restore errno properly.
3935 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3937 Remove redundant or unused things here and there.
3938 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
3939 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
3940 * editfns.c (Fcompare_buffer_substrings): Likewise.
3941 * frame.h (struct terminal, struct font_driver_list):
3942 Remove redundant declarations.
3943 * window.h (Qleft, Qright): Likewise.
3945 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3947 Do not mark objects from deleted buffers, windows and frames.
3948 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
3949 (mark_object): Likewise for windows and frames.
3951 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3953 * alloc.c (valid_lisp_object_p): Treat killed buffers,
3954 buffer_defaults and buffer_local_symbols as valid objects.
3955 Return special value to denote them.
3957 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
3959 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
3960 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
3961 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
3962 (file_name_absolute_p, Fsubstitute_in_file_name):
3963 (check_executable, check_writable, Ffile_accessible_directory_p)
3964 (Fset_file_selinux_context, Fdefault_file_modes)
3965 (Finsert_file_contents, choose_write_coding_system)
3966 (Fwrite_region, build_annotations, a_write, e_write)
3968 * filelock.c (boot_time_initialized, get_boot_time)
3969 (get_boot_time_1, lock_file_1, within_one_second):
3970 * floatfns.c (in_float):
3971 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
3972 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
3973 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
3974 * lisp.h (struct Lisp_Hash_Table.cmpfn):
3975 * window.c (compare_window_configurations):
3976 Use bool for booleans.
3977 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
3978 (Fdefault_file_modes): Now mode_t, not int, for modes.
3979 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
3980 (internal_delete_file): Now returns void, not a (boolean) int,
3981 since nobody was looking at the return value.
3982 * lisp.h, window.h: Adjust to above API changes.
3984 * xdisp.c (set_message): Simplify and reindent last change.
3986 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
3988 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
3990 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
3992 * eval.c (call_debugger): Make the function non-static so that we
3993 can call it from set_message.
3995 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
3996 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
3998 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4000 Give more-useful info on a fatal error (Bug#12328).
4001 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
4002 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
4003 of doing the work ourselves.
4004 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
4005 do most of the work.
4006 (fatal_error_backtrace): New function, taken from the guts
4007 of the old fatal_error_signal, but with a new option to output
4009 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
4010 info about the signal than just its number.
4011 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
4012 * sysdep.c: Include <execinfo.h>
4013 (emacs_backtrace): New function, taken partly from the previous
4014 code of the 'die' function.
4015 (emacs_abort): Call fatal_error_backtrace rather than abort.
4017 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
4019 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
4020 eager (load-time) macro-expansion.
4021 * lisp.mk (lisp): Add macroexp.
4023 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4025 Simplify redefinition of 'abort' (Bug#12316).
4026 Do not try to redefine the 'abort' function. Instead, redo
4027 the code so that it calls 'emacs_abort' rather than 'abort'.
4028 This removes the need for the NO_ABORT configure-time macro
4029 and makes it easier to change the abort code to do a backtrace.
4030 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
4031 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
4032 Remove; sysdep.c's emacs_abort now takes its place.
4033 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
4034 'abort' changed to use 'emacs_abort'.
4035 * msdos.c (dos_abort) [defined abort]: Remove; not used.
4036 (abort) [!defined abort]: Rename to ...
4037 (emacs_abort): ... new name.
4038 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
4039 the place of the old 'abort' in emacs.c.
4040 * w32.c, w32fns.c (abort): Do not #undef.
4041 * w32.c (emacs_abort): Rename from w32_abort.
4043 2012-09-04 Eli Zaretskii <eliz@gnu.org>
4045 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
4046 offsets[j].dv, since the y axis of the screen coordinates points
4047 down, while the y axis of the font definition coordinates points
4048 up. This fixes display of Arabic diacritics such as KASRA and
4049 KASRATAN. (Bug#11860)
4051 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4053 Be more systematic about _setjmp vs setjmp.
4054 * alloc.c (test_setjmp, mark_stack):
4055 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
4056 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
4057 (png_load, my_error_exit, jpeg_load):
4058 * process.c (send_process_trap, send_process):
4059 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
4060 The underscored versions are up to 30x faster on some hosts.
4061 Formerly, the code used setjmp+longjmp sometimes and
4062 _setjmp+_longjmp at other times, with no particular reason to
4063 prefer setjmp+longjmp.
4065 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
4067 Fix minor problem found by static checking.
4068 * buffer.c (Fdelete_all_overlays): Return nil.
4070 2012-09-03 Martin Rudalics <rudalics@gmx.at>
4072 * buffer.c (Fdelete_all_overlays): New function.
4074 2012-09-03 Chong Yidong <cyd@gnu.org>
4076 * gtkutil.c: Add extern decl for Qxft.
4078 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
4080 * emacs.c, eval.c: Use bool for boolean.
4081 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
4082 (malloc_using_checking) [DOUG_LEA_MALLOC]:
4083 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
4084 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
4085 (main, decode_env_path, Fdaemon_initialized):
4086 * eval.c (call_debugger, Finteractive_p, interactive_p):

4089 * process.c (read_process_output, exec_sentinel):
4090 Use bool for booleans.
4091 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
4092 All callers changed.
4093 * eval.c (interactive_p): Omit always-true boolean argument
4094 EXCLUDE_SUBRS_P. All callers changed.
4095 * dispextern.h, lisp.h: Reflect above API changes.
4096 * firstfile.c (dummy): Use the address of 'main', whose signature
4097 won't change, instead of the address of 'initialize', whose
4098 signature just changed from int to bool.

4100 * msdos.c (fatal_error_in_progress): ... from here.
4101 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
4103 (redisplay_internal, unwind_redisplay): Simply clear
4104 REDISPLAYING_P when unwinding, instead of saving its previous,
4105 always-false value and then restoring it.
4107 Clean up some extern decls.
4108 Mostly, this hoists extern decls out of .c files and into .h files.
4109 That way, we're more likely to catch errors if the interfaces change.

4141 this host are not needed to compile C files on this host.

4195 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
4196 more than one grapheme cluster passed to the shaper: compute the
4197 offset adjustment values separately for each cluster. (Bug#11860)
4199 * image.c: Restore mistakenly removed inclusion of w32.h. Without
4200 it, GCC doesn't see prototypes of w32_delayed_load, and complains
4201 about implicit conversions from integer to pointer.
4203 2012-09-01 Daniel Colascione <dancol@dancol.org>
4205 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window

4259 window system declarations.
4261 * frame.h: Move common functions here: set_frame_menubar,
4262 x_set_window_size, x_sync, x_get_focus_frame,
4263 x_set_mouse_position, x_set_mouse_pixel_position,
4264 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

4295 * term.c (mark_ttys): Remove.
4296 (init_tty): Safely initialize 'top_frame' slot with Qnil.

4323 2012-08-30 Glenn Morris <rgm@gnu.org>
4325 * lread.c (init_lread): For out-of-tree builds, only add the
4326 source directory's site-lisp dir to the load-path if it exists,
4327 consistent with in-tree builds. (Bug#12302)
4329 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

4350 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
4351 Add window_closed and button_values. Add void as return value for
4352 add(Button|String|Split). addButton takes int instead of Lisp_Object.
4353 Add process_dialog as new member.

4536 (syms_of_data): Do not define 'interval'.
4537 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
4538 * window.h (decode_valid_window):
4541 * character.c, charset.c, chartab.c: Use bool for booleans.
4542 * character.c (lisp_string_width, string_count_byte8)
4543 (string_escape_byte8):
4544 * charset.c (charset_map_loaded, load_charset_map, read_hex):
4545 (load_charset_map_from_file, map_charset_chars)
4546 (Fdefine_charset_internal, define_charset_internal)
4547 (Fdeclare_equiv_charset, find_charsets_in_text)
4548 (Ffind_charset_region, char_charset, Fiso_charset):
4549 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
4550 (sub_char_table_set, sub_char_table_set_range)
4551 (char_table_set_range, optimize_sub_char_table)
4552 (map_sub_char_table):
4553 Use bool for boolean.
4554 * character.c (str_to_unibyte): Omit last boolean argument; it was
4555 always 0. All callers changed.
4556 * character.h, charset.h: Adjust to match previous changes.
4557 * character.h (char_printable_p): Remove decl of nonexistent function.
4558 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
4559 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
4560 are all boolean, so make them single-bit bitfields.
4562 * lisp.h (ASET): Remove attempt to detect side effects.
4563 It was meant to be temporary and it often doesn't work,
4564 because when IDX has side effects the behavior of IDX==IDX
4565 is undefined. See Stefan Monnier in
4566 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
4568 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
4570 * lisp.h (functionp): New function (extracted from Ffunctionp).
4571 (FUNCTIONP): Use it.
4572 * eval.c (Ffunctionp): Use it.
4574 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
4576 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
4577 as that's faster and simpler than static storage. Don't bother
4578 with the g_main_context_query overhead if g_main_context_pending
4579 says no events are pending.
4580 (gfds, gfds_size): Remove these static vars.
4581 (xgselect_initialize): Remove; no longer needed.
4582 All uses and decls removed.
4584 * emacs.c (fatal_error_signal_hook): Remove.
4585 All uses removed. This leftover from old code was always 0.
4587 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
4588 * casefiddle.c (casify_object, casify_region):
4589 * casetab.c (set_case_table):
4590 * category.c, category.h (word_boundary_p):
4591 * category.h (CHAR_HAS_CATEGORY):
4592 Use bool for booleans, instead of int.
4594 2012-08-25 Eli Zaretskii <eliz@gnu.org>
4596 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
4598 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
4600 On assertion failure, print backtrace if available.
4601 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
4602 (die) [ENABLE_CHECKING]: Print a backtrace if available.
4603 * Makefile.in (LIB_EXECINFO): New macro.
4606 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
4607 * bytecode.c (exec_byte_code):
4608 * callint.c (check_mark, Fcall_interactively):
4609 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
4610 (getenv_internal, sync_process_alive, call_process_exited):
4611 * lisp.h (USE_SAFE_ALLOCA):
4612 Use bool for booleans, instead of int.
4613 * lisp.h, process.h: Adjust prototypes to match above changes.
4614 * callint.c (Fcall_interactively): Don't assume the mark's
4615 offset fits in 'int'.
4617 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
4619 * buffer.c, buffer.h: Use bool for boolean.
4620 * buffer.c (reset_buffer_local_variables)
4621 (buffer_lisp_local_variables, Fset_buffer_modified_p)
4622 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
4623 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
4624 (overlay_touches_p, overlay_strings, Foverlay_put)
4625 (report_overlay_modification, call_overlay_mod_hooks):
4626 (mmap_enlarge, mmap_set_vars):
4627 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
4628 Use bool for booleans, instead of int.
4629 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
4630 since the 1-or-0 return value is always ignored anyway.
4631 (mmap_initialized_p):
4632 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
4633 * buffer.h, lisp.h: Adjust prototypes to match above changes.
4635 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
4637 * bidi.c: Use bool for boolean.
4638 This is a bit more readable, and makes the text segment of bidi.o
4639 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
4640 Presumably it's faster too.
4641 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
4643 (bidi_cache_find_level_change, bidi_cache_iterator_state)
4644 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
4645 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
4646 (bidi_explicit_dir_char, bidi_level_of_next_char)
4647 (bidi_find_other_level_edge, bidi_move_to_visually_next):
4648 Use bool for booleans, instead of int.
4649 * dispextern.h (bidi_init_it, bidi_paragraph_init)
4650 (bidi_unshelve_cache): Adjust decls to match code.
4652 2012-08-23 Martin Rudalics <rudalics@gmx.at>
4654 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
4657 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
4659 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
4660 * atimer.h: Include <stdbool.h>.
4662 2012-08-22 Dan Nicolaescu <dann@gnu.org>
4664 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
4665 compile time tests instead of run time tests on systems that do
4667 (FRAME_MAC_P): Remove leftover from deleted code.
4668 * frame.c (syms_of_frame): Remove leftover from deleted code.
4670 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
4672 * nsterm.m (insertText:): Don't clear modifiers if code is space.
4674 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
4676 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
4677 Otherwise, the compiler complains about (A?B:C) where B is void
4678 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
4679 (fontset_add): Return void, for FONTSET_ADD.
4681 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4683 * alloc.c: Use bool for booleans.
4684 (gc_in_progress, abort_on_gc)
4685 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
4686 (dont_register_blocks) [GC_MALLOC_CHECK]:
4687 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
4688 (check_string_bytes, make_specified_string, memory_full)
4689 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
4690 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
4691 (mark_stack, valid_pointer_p, make_pure_string)
4692 (Fgarbage_collect, survives_gc_p, gc_sweep):
4693 Use bool for booleans, instead of int.
4694 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
4695 Remove unused local.
4696 * alloc.c (PURE_POINTER_P):
4697 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
4698 * editfns.c (Fformat):
4699 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
4701 * fns.c (sweep_weak_table):
4702 * lisp.h (suppress_checking, push_message, survives_gc_p)
4703 (make_pure_string, gc_in_progress, abort_on_gc):
4704 * lread.c (readchar, read1):
4705 * print.c (Fprin1_to_string):
4706 * xdisp.c (push_message):
4707 Use bool for booleans affected directly or indirectly by
4710 Make recently-introduced setters macros.
4711 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
4712 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
4713 (set_fontset_default, set_fontset_fallback): Rename from their
4714 upper-case counterparts, and make them functions rather than macros.
4715 This is more consistent with the other recently-introduced setters.
4716 These don't need to be inline, since they're local.
4718 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
4720 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
4721 the loop (Bug#12247).
4723 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4725 * lisp.h (vcopy): Use memcpy rather than our own loop.
4726 This fixes a performance regression introduced by the recent
4727 addition of vcopy. This means 'vcopy' will need to be modified
4728 for a copying collector, but that's OK. Also, tighten the
4729 checking in the assertion.
4731 2012-08-21 Eli Zaretskii <eliz@gnu.org>
4733 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
4734 components for RTL text (Bug#11860). Adjust X-OFFSET of each
4735 non-base glyph for the width of the base character, according to
4736 what x_draw_composite_glyph_string_foreground expects.
4737 Generate WADJUST value according to composition_gstring_width's
4738 expectations, to produce correct width of the composed character.
4739 Reverse the sign of the DU offset produced by ScriptPlace.
4741 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
4743 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
4745 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
4747 Avoid direct writes to contents member of struct Lisp_Vector.
4748 * lisp.h (vcopy): New function to copy data into vector.
4749 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
4750 * fns.c (Ffillarray): Use ASET.
4751 * keyboard.c (timer_check_2): Use AREF and ASET.
4752 (append_tool_bar_item, Frecent_keys): Use vcopy.
4753 * lread.c (read_vector): Use ASET.
4754 * msdos.c (Frecent_doskeys): Use vcopy.
4755 * xface.c (Finternal_copy_lisp_face): Use vcopy.
4756 (Finternal_merge_in_global_face): Use ASET and vcopy.
4757 * xfont.c (xfont_list_pattern): Likewise.
4759 2012-08-21 Martin Rudalics <rudalics@gmx.at>
4761 * window.c (Fwindow_point): For the selected window always return
4762 the position of its buffer's point.
4763 (Fset_window_point): For the selected window always go in its
4764 buffer to the specified position.
4766 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
4768 Setter macros for fontsets.
4769 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
4770 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
4771 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
4774 2012-08-20 Glenn Morris <rgm@gnu.org>
4776 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
4777 Don't assume that `ln -f' works.
4779 2012-08-20 Eli Zaretskii <eliz@gnu.org>
4781 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
4782 and later about non-assignments with no effect. See discussion at
4783 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
4786 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
4788 Inline setter functions for Lisp_Objects slots of struct specbinding.
4789 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
4792 2012-08-20 Martin Rudalics <rudalics@gmx.at>
4794 * window.c (select_window): Always make selected window's buffer
4797 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
4799 Use AREF and ASET for docstrings of category tables.
4800 * category.h (CATEGORY_DOCSTRING): Use AREF.
4801 (SET_CATEGORY_DOCSTRING): Use ASET.
4802 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
4804 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
4806 Inline setter functions for hash table members.
4807 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
4808 (set_hash_hash, set_hash_index): Rename with _slot suffix.
4809 (set_hash_key_and_value, set_hash_index, set_hash_next)
4810 (set_hash_hash): New functions.
4811 * charset.c, fns.c: Adjust users.
4813 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
4815 Inline getter and setter functions for per-buffer values.
4816 * buffer.h (per_buffer_default, set_per_buffer_default)
4817 (per_buffer_value, set_per_buffer_value): New functions.
4818 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
4819 * buffer.c, data.c: Adjust users.
4821 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
4823 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
4825 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
4827 Rely on <config.h> + <unistd.h> to declare 'environ',
4828 as gnulib does this if the system doesn't.
4829 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
4830 Remove declaration. MS-Windows declares it on stdlib.h which is
4831 included by conf_post.h.
4832 * emacs.c (environ) [DOUG_LEA_MALLOC]:
4833 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
4834 * vm-limit.c: Include <unistd.h>, for 'environ'.
4836 * unexaix.c, unexcoff.c: Include "mem-limits.h".
4837 (start_of_data): Remove decl; mem-limits.h provides it.
4839 * xdisp.c (handle_invisible_prop): Make it a bit faster
4840 and avoid a gcc -Wmaybe-uninitialized diagnostic.
4842 2012-08-19 Chong Yidong <cyd@gnu.org>
4844 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
4847 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
4849 * .gdbinit: Use call instead of set when calling a function in the
4852 * data.c (set_internal): Don't use set_blv_found.
4853 (Fkill_local_variable): Likewise.
4855 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
4857 * nsfont.m (ns_ascii_average_width): Ensure the string
4858 ascii_printable is initialized with a null-terminated character
4859 array. Otherwise, it can contain undesired extra characters.
4861 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
4863 port new setting code to Sun C 5.8 2005/10/13
4864 * chartab.c, lisp.h (char_table_set, char_table_set_range):
4865 Return void, not Lisp_Object. Otherwise, the compiler
4866 complains about (A?B:C) where B is void and C is Lisp_Object
4867 when compiling CHAR_TABLE_SET, due to the recent change to
4868 the API of sub_char_table_set_contents.
4870 2012-08-18 Chong Yidong <cyd@gnu.org>
4872 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
4873 for the string case (Bug#3874).
4875 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
4877 * buffer.h (BSET): Remove (Bug#12215).
4878 Replace all uses with calls to new setter functions.

4947 New setter functions.
4949 * termhooks.h (TSET): Remove (Bug#12215).
4950 Replace all uses with calls to new setter functions.
4951 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
4952 (TERMHOOKS_INLINE): New macro.
4953 (tset_charset_list, tset_selection_alist): New setter functions.
4954 * terminal.c (TERMHOOKS_INLINE):
4955 Define to EXTERN_INLINE, so that the corresponding functions
4956 are compiled into code.
4957 (tset_param_alist): New setter function.
4959 2012-08-17 Paul Eggert <eggert@cs.ucla.edu>
4961 * keyboard.h (KSET): Remove (Bug#12215).

5705 value of EMACSLOADPATH, as it is no longer needed.
5706 (check_windows_init_file): Now external, not static.

5757 * alloc.c (record_xmalloc): New function.
5758 * lisp.h (record_xmalloc): New decl.
5759 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
5760 more like a function. This is because the pointer cast is not
5761 needed. All uses changed.
5762 * print.c (print_string, print_error_message): Avoid length recalc.
5764 Improve fix for macroexp crash with debugging (Bug#12118).
5765 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
5766 ARRAY_MARK_FLAG when checking subscripts, because ASET is

5799 with addition of handling of symlinks and support for 'lstat'.
5800 If possible, get file's attributes and security information by
5801 handle, not by name. Produce S_IFLNK bit for symlinks, when
5802 called from 'lstat'.
5803 (stat, lstat): New functions, call 'stat_worker'.
5804 (symlink, readlink, careadlinkat): Rewritten to create and resolve
5805 symlinks when the underlying filesystem supports them.
5807 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
5809 Fix macroexp crash on Windows with debugging (Bug#12118).
5810 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
5811 checking subscripts; problem introduced with the recent
5812 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
5813 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
5814 since it's used in non-static inline functions now.
5816 * xfaces.c (face_at_buffer_position, face_for_overlay_string):

6308 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
6309 arms of an 'if', not using conditional expressions; otherwise GDB
6310 complains about the types in the unevaluated arm when the argument
6311 is an integer literal.
6312 (xgetint): Simplify expression.
6313 * alloc.c (gdb_make_enums_visible): New constant. This ports to
6314 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
6315 Zaretskii in <http://bugs.gnu.org/12036#13>.
6316 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
6317 needed now that we have gdb_make_enums_visible.
6318 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
6319 (enum enum_USE_LSB_TAG):
6320 New enum types, packaging up enums that need to be exported to GDB.
6322 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
6324 Utility function to make a list from specified amount of objects.

6338 * xdisp.c (syms_of_xdisp): Likewise.
6339 * xfns.c (syms_of_xfns): Likewise.
6341 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
6343 Fast save_excursion_save and save_excursion_restore.
6344 * lisp.h (struct Lisp_Excursion): New data type.
6345 (PVEC_EXCURSION): New pseudovector type.
6346 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
6347 to deal with it. Adjust comments.
6348 (init_marker, attach_marker): New prototype.
6349 (unchain_marker): Adjust prototype.
6350 * marker.c (attach_marker): Change to global.

6358 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
6360 Fix export of symbols to GDB (Bug#12036).
6361 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
6362 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
6363 emacs.c, as this is a more-suitable home. Had this been done earlier
6364 the fix for 12036 would have avoided some of the problems noted in
6365 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
6366 would have been more obvious.
6367 * emacs.c: Do not include <verify.h>; no longer needed.
6368 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
6369 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
6370 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
6371 Remove; now done in lisp.h.
6372 * lisp.h (PUBLISH_TO_GDB): New macro.
6373 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
6374 (DATA_SEG_BITS): Use it.
6375 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
6376 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
6377 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
6378 not be usable in #if. This simplifies things.
6380 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
6382 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
6384 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
6386 Simplify export of symbols to GDB (Bug#12036).
6387 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
6388 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
6389 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
6390 Adjust to changes in lisp.h and emacs.c, by using
6391 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
6392 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
6393 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
6394 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
6395 instead of gdb_valbits.
6396 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
6397 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
6398 instead of gdb_array_mark_flag.
6399 (xboolvector): Get size from $->size, not $->header.size.
6400 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
6401 (xreload, hook-run, hookpost-run): Remove.
6402 * emacs.c: Include <verify.h>.
6403 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
6404 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
6406 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
6407 (gdb_USE_LSB_TAG): New enum constants.
6408 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
6409 Also define these as enum constants, so they're visible to GDB.
6410 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
6411 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
6412 as constants, so they're visible to GDB.
6413 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
6414 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
6415 Now enum constants, not macros, so they're visible to GDB.
6416 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
6417 more convenient now. All uses changed.
6418 (VALMASK) [USE_LSB_TAG]: Also define in this case.
6419 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
6421 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

6428 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
6429 add argument, tune behavior, and adjust all callers.
6431 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
6433 Use typedef for EMACS_INT, EMACS_UINT.
6434 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
6435 than macros. This simplifies debugging in the usual case, since
6436 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
6437 and it allows expressions involving EMACS_INT casts.
6438 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
6440 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

6450 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
6452 Adjust buffer text indirection counters at the end of Fkill_buffer.
6453 * buffer.c (Fkill_buffer): Adjust indirection counters when the
6454 buffer is definitely dead. This should really fix an issue reported
6455 by Christoph Scholtes again. (Bug#12007).
6456 (init_buffer_once): Initialize indirection counters of
6457 buffer_defaults and buffer_local_symbols (for sanity and safety).
6459 2012-07-24 Eli Zaretskii <eliz@gnu.org>
6461 * xdisp.c (init_iterator): Don't compute dimensions of truncation
6462 and continuation glyphs on tooltip frames, leave them at zero.

6490 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
6492 Swap buffer text indirection counters in Fbuffer_swap_text.
6493 * buffer.c (Fbuffer_swap_text): Swap indirections too.
6494 This avoids crash reported by Christoph Scholtes at
6495 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
6497 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
6499 * nsmenu.m (Popdown_data): New struct.

6504 and autorelease them. Also autorelease img and matrix (Bug#12005).
6505 (dealloc): Remove (Bug#12005).

6522 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
6524 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
6525 as it's limited by the amount of memory, not by INT_MAX.
6527 2012-07-21 Eli Zaretskii <eliz@gnu.org>
6529 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
6530 in special-event-map. See the discussion at

6589 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
6590 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
6591 Adjust users accordingly.
6592 * font.h (font_open_by_name): Adjust prototype.

6611 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
6612 'for_each_per_buffer_object_at'.
6613 All uses changed. It's better to use upper-case for macros that
6614 cannot be implemented as functions, to give the reader a clue
6615 that they're special.
6617 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>
6619 * alloc.c (Fgarbage_collect): Tweak docstring.

6660 * intervals.c (merge_interval_right, merge_interval_left):
6661 Do not zero out this interval if it is absorbed by its children,
6662 as this interval's total length doesn't change in that case. See
6663 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00403.html>.
6665 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
6667 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
6668 when invoking (make-bool-vector N t) and N is a positive

6671 Remove some struct layout assumptions in bool vectors.
6672 * alloc.c (bool_header_size): New constant.
6673 (header_size, word_size): Move earlier, as they're now used earlier.

6676 padding before the data member of a bool vector.
6677 (sweep_vectors): Use PSEUDOVECTOR_TYPEP, in an eassert, rather
6678 than doing the check by hand with an abort ().
6680 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
6682 * eval.c (Fdefvar): Don't check constants since we only set the var if
6683 it's not yet defined anyway (bug#11904).
6685 * lisp.h (last_undo_boundary): Declare new var.
6686 * keyboard.c (command_loop_1): Set it.
6687 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
6688 were auto-added by the command loop (bug#11774).
6690 2012-07-18 Andreas Schwab <schwab@linux-m68k.org>
6692 * w32font.c (Qsymbol): Remove local definition.

7191 Move CLASH_DETECTION to configure.
7193 * s/gnu.h: Remove file, which is now empty.
7195 * s/gnu.h, s/gnu-linux.h:
7196 Move GNU_LIBRARY_PENDING_OUTPUT_COUNT to configure.
7198 2012-07-11 John Wiegley <johnw@newartisans.com>
7200 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
7201 function attribute, so we only use it if it exists in the
7204 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
7206 Avoid call to strlen in fast_c_string_match_ignore_case.
7207 * search.c (fast_c_string_match_ignore_case): Change to use
7208 length argument. Adjust users accordingly.
7209 * lisp.h (fast_c_string_match_ignore_case): Adjust prototype.
7211 2012-07-11 Paul Eggert <eggert@cs.ucla.edu>

7232 (font_open_by_name): Change to use length argument.
7233 Adjust users accordingly.
7234 * font.h (font_open_by_name, font_parse_xlfd, font_unparse_xlfd):
7236 * xfont.c (xfont_decode_coding_xlfd, font_unparse_xlfd):
7237 Change to return ptrdiff_t.
7238 (xfont_list_pattern, xfont_match): Use length returned by

7250 2012-07-10 Paul Eggert <eggert@cs.ucla.edu>
7252 Remove "#define unix" that is no longer needed (Bug#11905).
7253 * s/aix4-2.h (unix): Remove; no longer needed.
7255 EMACS_TIME simplification (Bug#11875).
7256 This replaces macros (which typically do not work in GDB)
7257 with functions, typedefs and enums, making the code easier to debug.
7258 The functional style also makes code easier to read and maintain.
7259 * systime.h: Include <sys/time.h> on all hosts, not just if
7260 WINDOWSNT, since 'struct timeval' is needed in general.
7261 (EMACS_TIME): Now a typedef, not a macro.
7262 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
7264 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

7266 (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE, EMACS_TIME_LT)
7267 (EMACS_TIME_LE): Now functions, not macros.
7268 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
7269 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
7270 which are not functions. All uses rewritten to use:
7271 (make_emacs_time): New function.
7272 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
7273 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
7274 not functions. All uses rewritten to use the following, respectively:
7275 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
7276 (add_emacs_time, sub_emacs_time): New functions.
7277 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
7278 * fileio.c (Fcopy_file):
7279 * xterm.c (XTflash): Get the current time closer to when it's used.
7280 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

7284 Simplify by avoiding confusing use of strncpy etc.
7285 * doc.c (Fsnarf_documentation):
7286 * fileio.c (Ffile_name_directory, Fsubstitute_in_file_name):
7287 * frame.c (Fmake_terminal_frame):
7288 * gtkutil.c (get_utf8_string):
7290 * nsmenu.m (ns_update_menubar):
7291 * regex.c (regerror):
7292 Prefer memcpy to strncpy and strncat when either will do.
7293 * fileio.c (Fsubstitute_in_file_name):
7294 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
7295 (menu_separator_name_p):
7296 * nsmenu.m (ns_update_menubar):
7297 Prefer memcmp to strncmp when either will do.
7298 * nsterm.m: Include <ftoastr.h>.
7300 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
7301 Prefer snprintf to strncpy.
7302 * nsterm.m (ns_term_init):
7303 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
7304 * nsterm.m (ns_term_init):
7305 Avoid the need for strncpy, by using build_string or
7306 make_unibyte_string directly. Use dtoastr, not snprintf.
7307 * process.c (Fmake_network_process): Diagnose service names that
7308 are too long, rather than silently truncating them or creating
7309 non-null-terminated names.
7310 (Fnetwork_interface_info): Likewise, for interface names.
7311 * sysdep.c (system_process_attributes) [GNU_LINUX]:
7312 Prefer sprintf to strncat.
7313 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
7314 Prefer vsnprintf to vsprintf + strncpy.
7316 2012-07-10 Glenn Morris <rgm@gnu.org>
7318 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
7319 Clarify fallback case.
7321 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
7323 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
7324 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
7325 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
7326 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
7327 where argument type is known to be a Lisp_Cons.
7329 2012-07-10 Tom Tromey <tromey@redhat.com>
7331 * bytecode.c (BYTE_CODE_THREADED): New macro.
7332 (BYTE_CODES): New macro. Replaces all old byte-code defines.
7333 (enum byte_code_op): New type.
7334 (CASE, NEXT, FIRST, CASE_DEFAULT, CASE_ABORT): New macros.

7337 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
7339 Optimize pure C strings initialization.
7340 * lisp.h (make_pure_string): Fix prototype.
7341 (build_pure_c_string): New function, defined as static inline. This
7342 provides a better opportunity to optimize away calls to strlen when
7343 the function is called with compile-time constant argument.
7344 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
7345 argument, adjust users accordingly. Use build_pure_c_string where
7347 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
7348 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
7349 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
7351 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
7353 Avoid calls to strlen in miscellaneous functions.
7354 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
7355 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
7356 * lread.c (openp): Likewise.
7358 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
7360 Avoid calls to strlen in path processing functions.
7361 * fileio.c (file_name_as_directory): Add comment. Change to add
7362 srclen argument and return the length of result. Adjust users
7364 (directory_file_name): Fix comment. Change to add srclen argument,
7365 swap 1st and 2nd arguments to obey the common convention.
7366 Adjust users accordingly.
7367 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
7369 2012-07-10 Glenn Morris <rgm@gnu.org>
7371 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
7372 Move PENDING_OUTPUT_COUNT definition to configure.
7374 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
7375 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
7376 * s/gnu.h (DATA_START): Move definitions to configure.
7378 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
7379 We include usg5-4-common.h, which defines them both.
7381 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
7382 O_RDONLY already includes it).
7384 Stop ns builds setting the EMACSLOADPATH environment variable.
7385 * nsterm.m (ns_load_path): Rename from ns_init_paths.
7386 Now it does not set EMACSLOADPATH, just returns the load-path string.
7387 * nsterm.h: Update accordingly.
7388 * lread.c [HAVE_NS]: Include nsterm.h.
7389 (init_lread) [HAVE_NS]: Use ns_load_path.
7390 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
7392 2012-07-09 Glenn Morris <rgm@gnu.org>
7394 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
7395 since the included bsd-common.h does so.
7397 Stop ns builds setting the EMACSPATH environment variable.
7398 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
7399 (ns_init_paths): Do not set EMACSPATH.
7400 * nsterm.h (ns_exec_path): Add it.
7401 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
7404 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
7406 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
7408 * process.c (wait_reading_process_output): 'waitchannels' was unset
7409 when read_kbd || !NILP (wait_for_cell); fix this.
7411 Add GCC-style 'const' attribute to functions that can use it.
7412 * character.h (char_resolve_modifier_mask):
7413 * keyboard.h (make_ctrl_char):
7414 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
7415 (init_character_once, next_almost_prime, init_fns, init_image)
7416 (flush_pending_output, init_sound):
7417 * mem-limits.h (start_of_data):
7418 * menu.h (finish_menu_items):
7419 Add ATTRIBUTE_CONST.

7421 Declare the dummy function with ATTRIBUTE_CONST.
7422 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
7423 Add decls with ATTRIBUTE_CONST.
7425 Minor improvements to make_formatted_string.
7426 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
7427 where int is good enough, as vsprintf returns an int.
7428 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
7430 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7432 Use make_formatted_string to avoid double length calculation.
7433 * lisp.h (make_formatted_string): New prototype.

7439 * frame.c (make_terminal_frame, set_term_frame_name)
7440 (x_report_frame_params): Likewise.
7441 * image.c (gs_load): Likewise.
7442 * minibuf.c (get_minibuffer): Likewise.

7457 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
7459 Move marker debugging code under MARKER_DEBUG.
7460 * marker.c (MARKER_DEBUG): Move marker debugging code under
7461 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
7462 for bootstrap with --enable-checking (~3x slowdown reported
7463 by Juanma Barranquero <lekktu@gmail.com>).
7464 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
7466 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
7468 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
7469 See <http://bugs.gnu.org/11825#29>.
7471 2012-07-08 Eli Zaretskii <eliz@gnu.org>
7473 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
7474 has no font, use the frame's font. (Bug#11813)
7475 (display_line): Add commentary about displaying truncation glyphs
7477 (produce_special_glyphs): Move here from term.c.
7479 * term.c (produce_special_glyphs): Move to xdisp.c.
7481 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
7484 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
7486 * xdisp.c (display_line): Avoid warning about implicit declaration
7489 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
7491 * lisp.h: Remove empty conditional.
7493 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
7495 * lread.c (load_path_check): Now static.
7497 Fix some minor --with-ns problems found by static checking.
7498 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
7499 (x_set_font) [!HAVE_X_WINDOWS]:
7500 * image.c (xpm_load_image) [HAVE_NS]:
7501 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
7502 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
7503 Remove unused local.
7504 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
7505 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
7506 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
7507 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
7508 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
7509 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
7510 Fix pointer signedness problem.
7511 * xfaces.c (FRAME_X_FONT_TABLE):
7512 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
7514 2012-07-07 Glenn Morris <rgm@gnu.org>
7516 * lread.c (load_path_check): New function, split from init_lread.
7517 (init_lread): Reorganize. Motivation:
7518 If EMACSLOADPATH is set, check/warn about that rather than the
7519 defaults, which we are not going to use. Hence we can remove
7520 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
7521 Don't warn if site-lisp directories are missing.
7522 If not installed, start from a blank load-path, since
7523 PATH_LOADSEARCH refers to the eventual installation directories.
7525 2012-07-07 Eli Zaretskii <eliz@gnu.org>
7527 Support truncation and continuation glyphs on GUI frames, when
7528 fringes are disabled. (Bug#11832)
7529 * xdisp.c (init_iterator): Get dimensions of truncation and
7530 continuation glyphs even if on GUI frames.
7531 Adjust it->last_visible_x on GUI frames when the left or right fringes,
7532 or both, are absent.
7533 (start_display, move_it_in_display_line_to): Handle the case of a
7534 GUI frame without a fringe to display continuation or truncation
7536 (insert_left_trunc_glyphs): Support GUI frames: make sure
7537 truncation glyphs overwrite enough glyphs from the current line to
7538 have sufficient space in pixels.
7539 (display_line): Support truncation and continuation glyphs on GUI
7540 frames. If some spare pixels are left on the line after inserting
7541 the truncation glyphs, fill that space with a stretch glyph of a
7542 suitably computed width.
7544 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
7545 produce_glyphs, to support GUI sessions.
7547 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
7549 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
7551 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
7553 Do not require float-time's arg to fit in time_t (Bug#11825).
7554 This works better on hosts where time_t is unsigned, and where
7555 float-time is applied to the (negative) difference between two times.
7556 * editfns.c (decode_time_components): Last arg is now double *,
7557 not int *, and means to store all the result as a double, without
7558 worrying about whether the seconds part fits in time_t.
7559 All callers changed.
7560 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
7561 All callers changed.
7562 (Ffloat_time): Do not fail merely because the specified time falls
7563 outside of time_t range.
7565 2012-07-07 Glenn Morris <rgm@gnu.org>
7567 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

7571 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
7573 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
7574 Update dependencies.
7576 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
7578 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7580 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
7581 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
7582 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
7583 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
7584 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
7585 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
7587 * xfont.c (compare_font_names): Redo to omit the need for casts.
7589 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
7591 * xfns.c (Fx_change_window_property): Doc fix.
7592 * w32fns.c (Fx_change_window_property): Doc fix.
7594 * w32fns.c (Fx_window_property): Accept the same arguments as the
7595 X Windows version. Doc fix.
7596 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
7598 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
7599 Eli Zaretskii <eliz@gnu.org>
7601 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
7602 Windows-specific code from nt/config.nt moved here.
7603 Obsolete settings removed.
7605 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7607 * process.c: Avoid unnecessary calls to gettime.
7608 (wait_reading_process_output): Don't get the time of day
7609 when gobbling data immediately and not waiting, as there's no need
7610 for it in that case. This removes a FIXME.
7612 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
7614 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
7615 is defined (Bug#11768).
7617 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7619 Fix marker debugging code.
7620 * marker.c (byte_char_debug_check): Do not perform the check
7621 if buffer is not multibyte.
7622 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
7623 Call byte_char_debug_check with correct arguments.
7625 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7627 Compile marker debugging code only if ENABLE_CHECKING is defined.
7628 * marker.c (byte_char_debug_check, count_markers):
7629 Use only if ENABLE_CHECKING is defined.
7630 (byte_debug_flag): Remove.
7631 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
7632 Always call byte_char_debug_check if ENABLE_CHECKING is defined.

7636 Avoid code repetition in marker-related functions.
7637 * marker.c (attach_marker): New function.
7638 (Fset_marker, set_marker_restricted, set_marker_both)
7639 (set_marker_restricted_both): Use it.
7640 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
7641 Consistently rename charno to charpos.
7642 (marker_position): Add eassert.
7643 (marker_byte_position): Convert to eassert.
7645 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7647 Simplify list operations in unchain_overlay and unchain_marker.
7648 * buffer.c (unchain_overlay): Simplify. Add comment.
7649 * marker.c (unchain_marker): Simplify. Fix comments.
7651 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
7653 Introduce fast path for the widely used marker operation.
7654 * alloc.c (build_marker): New function.
7655 * lisp.h (build_marker): New prototype.
7656 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
7657 * composite.c (autocmp_chars): Likewise.
7658 * editfns.c (buildmark): Remove.
7659 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
7660 (save_restriction_save): Use build_marker.
7661 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
7662 * window.c (save_window_save): Likewise.
7664 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

7667 to avoid redundant calls to unchain_overlay.
7668 * buffer.c (drop_overlay): New function.
7669 (delete_all_overlays, Fdelete_overlay): Use it.
7670 * minibuf.c (get_minibuffer): Fix comment.
7672 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
7674 Port to OpenBSD 5.1 amd64.
7675 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
7676 This is needed for OpenBSD, and should be harmless on all BSD systems.
7677 Also, include <sys/sysctl.h>, as it should be available on all
7678 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
7679 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
7680 use p_pid member, not kp_proc.pid.
7682 2012-07-06 Glenn Morris <rgm@gnu.org>
7684 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
7686 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
7688 More xmalloc and related cleanup.
7689 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

7696 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
7697 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
7699 Omit needless casts involving void * pointers and allocation.
7700 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
7701 as the former is more robust if P's type is changed.
7702 Prefer xzalloc to xmalloc + memset 0.
7703 Simplify malloc-or-realloc to realloc.
7704 Don't worry about xmalloc returning a null pointer.
7705 Prefer xstrdup to xmalloc + strcpy.
7706 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
7708 * keyboard.c (apply_modifiers_uncached): Prefer local array to
7709 alloca of a constant.
7711 2012-07-05 Eli Zaretskii <eliz@gnu.org>
7713 * xdisp.c (display_line): Fix horizontal pixel coordinates when
7714 hscroll is larger than the line width. Fixes long and futile
7715 looping inside extend_face_to_end_of_line (on a TTY) producing
7716 glyphs that are not needed and thrown away.
7718 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
7720 * marker.c (set_marker_restricted_both): Simplify by using
7723 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
7725 * editfns.c (region_limit): Simplify by using clip_to_bounds.
7727 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
7729 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
7730 not defined (Bug#11768).
7731 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
7732 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
7733 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
7734 followed by gtk_box_set_homogeneous (Bug#11768).
7735 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
7736 (update_theme_scrollbar_width, xg_create_scroll_bar):
7737 Use gtk_scrollbar_new (Bug#11768).
7738 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
7739 (is_box_type): New function (Bug#11768).
7740 (xg_tool_item_stale_p): Call is_box_type.
7741 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
7742 with default display (Bug#11768).

7746 * xdisp.c (window_hscroll_limited): New function.
7747 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
7748 coordinates when window's hscroll is set to insanely large
7751 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
7753 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

7756 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
7759 * lisp.h (xzalloc): New prototype. Omit needless casts.
7760 * alloc.c (xzalloc): New function. Omit needless casts.
7761 * charset.c: Omit needless casts. Convert all calls to
7762 xmalloc with following memset to xzalloc.

7812 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
7814 * fileio.c (time_error_value): Check the right error number.
7815 Problem reported by Troels Nielsen in
7816 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
7818 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7820 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
7821 This should be fixed in a better way; see Eli Zaretskii in
7822 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
7823 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
7825 * fileio.c (time_error_value): Rename from special_mtime.
7826 The old name's problems were noted by Eli Zaretskii in
7827 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
7829 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
7830 This variable's comment says Emacs needs at least one GDB-visible
7831 symbol of type enum pvec_type, to work around GDB problems.
7832 The symbol's value doesn't matter.
7834 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
7835 that causes compilation to fail on pre-C99 compilers.
7837 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
7839 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
7840 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
7842 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
7844 * buffer.c (init_buffer_once): Fix initialization of
7845 headers for buffer_defaults and buffer_local_symbols.
7846 Reported by Juanma Barranquero <lekktu@gmail.com>.
7848 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
7850 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
7851 * lisp.h (enum pvec_type): Use fewer bits.
7852 (PSEUDOVECTOR_SIZE_BITS): New constant.
7853 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
7854 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
7855 change in pvec_type.
7856 (PSEUDOVECTOR_TYPEP): New macro.
7857 (TYPED_PSEUDOVECTORP): Use it.
7858 * fns.c (internal_equal): Adapt code to extract pvectype.

7860 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
7861 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
7862 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
7863 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
7864 (sweep_vectors): Use it. Use local var `total_bytes' instead of
7865 abusing vector->header.next.nbytes.
7866 (live_vector_p): Use PVEC_TYPE.
7867 (mark_object): Adapt code to extract pvectype. Use switch.
7869 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7871 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
7872 Tighten new eassert a bit.
7874 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
7876 Fix compilation with --enable-gcc-warnings and -O1
7878 * doprnt.c (doprnt): Change type of tem to int, initialize
7879 to avoid compiler warning. Add eassert.
7880 * search.c (simple_search): Initialize match_byte to avoid
7881 compiler warning. Add eassert.
7883 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7885 Avoid weird behavior with large horizontal scrolls.
7886 Without this change, for example, large hscroll values would
7887 mess up Emacs's display on Fedora 15 x86, presumably due to
7888 overflows in int calculations in the display code.
7889 Also, if buffers had long lines, Emacs would freeze.
7890 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
7891 (set_window_hscroll): New function, containing the old guts of
7892 Fset_window_hscroll. Return the clipped value.
7893 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
7894 This avoids the need to check against PTRDIFF_MAX.
7896 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
7898 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
7900 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
7902 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7904 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
7905 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
7906 since GCC 4.4.6 issues a bogus warning for them.
7908 Fix bugs in file timestamp newness comparisons.
7909 * fileio.c (Ffile_newer_than_file_p):
7910 * lread.c (Fload): Use full timestamp resolution of files,
7911 not just the 1-second resolution, so that files that are only
7912 slightly newer still count as newer.
7913 * fileio.c (Ffile_newer_than_file_p): Don't assume file
7914 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
7916 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
7918 * fileio.c: Improve handling of file time marker. (Bug#11852)
7919 (special_mtime): New function.
7920 (Finsert_file_contents, Fverify_visited_file_modtime):
7921 Use it to set special mtime values consistently.
7923 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
7925 * fileio.c (Finsert_file_contents): Properly handle st_mtime
7926 marker for non-existing file. (Bug#11852)
7928 2012-07-03 Glenn Morris <rgm@gnu.org>
7930 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
7931 and did not make it into globals.h).
7933 2012-07-03 Tom Tromey <tromey@redhat.com>
7935 * window.c (Fset_window_margins, Fset_window_fringes)
7936 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
7937 * textprop.c (Fprevious_property_change): No longer static.
7938 * syntax.c (Fsyntax_table_p): No longer static.
7939 * process.c (Fget_process, Fprocess_datagram_address): No longer

7953 * dired.c (Ffile_attributes): No longer static.
7954 * composite.c (Fcomposition_get_gstring): No longer static.
7955 * callproc.c (Fgetenv_internal): No longer static.
7957 * ccl.h: Remove EXFUNs.
7958 * buffer.h: Remove EXFUNs.
7959 * dispextern.h: Remove EXFUNs.
7960 * intervals.h: Remove EXFUNs.
7961 * fontset.h: Remove EXFUN.
7962 * font.h: Remove EXFUNs.
7963 * dosfns.c (system_process_attributes): Remove EXFUN.
7964 * keymap.h: Remove EXFUNs.
7965 * lisp.h: Remove EXFUNs.
7966 * w32term.h: Remove EXFUNs.
7967 * window.h: Remove EXFUNs.
7968 * xsettings.h: Remove EXFUN.
7969 * xterm.h: Remove EXFUN.
7971 2012-07-03 Glenn Morris <rgm@gnu.org>
7973 * lisp.h (Frandom): Make it visible to C.
7974 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
7975 buffer for invisible buffers. (Bug#1229)
7977 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7979 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
7980 values which aren't power of 2.
7981 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
7982 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
7985 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
7987 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
7989 * alloc.c (mark_object): Revert part of last patch to use `switch'.
7991 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7993 * alloc.c (allocate_vector_block): Remove redundant
7994 calls to mallopt if DOUG_LEA_MALLOC is defined.
7995 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
7996 avoid calls to mallopt if zero_vector is returned.
7998 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8000 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
8001 is enabled, avoid dereferencing NULL current_sblock if
8004 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8006 Cleanup basic buffer management.
8007 * buffer.h (struct buffer): Change layout to use generic vector
8008 marking code. Fix some comments. Change type of 'clip_changed'
8009 to bitfield. Remove unused #ifndef old.
8010 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
8011 (GET_OVERLAYS_AT): Fix indentation.
8012 (for_each_per_buffer_object_at): New macro.
8013 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
8014 (Fbuffer_local_variables): Use it.
8015 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
8016 * alloc.c (allocate_buffer): Adjust to match new layout of
8017 struct buffer. Fix comment.
8018 (mark_overlay): New function.
8019 (mark_buffer): Use it. Use mark_vectorlike to mark normal
8020 Lisp area of struct buffer.
8021 (mark_object): Use it. Adjust marking of misc objects
8022 and related comments.
8024 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
8026 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
8027 wrapper that is not needed because the wrapped code is a no-op (zero
8028 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
8029 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
8031 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
8033 * alloc.c (mark_buffer): Simplify. Remove prototype.
8034 (mark_object): Add comment. Reorganize marking of vector-like
8035 objects. Use CHECK_LIVE for all vector-like objects except buffers
8036 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
8037 Avoid redundant calls to mark_vectorlike for bool vectors.
8039 2012-06-30 Glenn Morris <rgm@gnu.org>
8041 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
8043 * epaths.in (PATH_SITELOADSEARCH): New.
8044 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
8045 This is rather than relying on --enable-locallisppath elements
8046 having "site-lisp" in their names. (Bug#10208#25, 11658)
8048 2012-06-30 Eli Zaretskii <eliz@gnu.org>
8050 * w32proc.c (sys_select): Accept and ignore one more argument.
8052 * w32.c (emacs_gnutls_pull): Call select with one more argument.
8054 * sysselect.h [DOS_NT]: Don't include sys/select.h.
8055 (pselect) [!MS_DOS]: Redirect to sys_select.
8057 * sysdep.c: Don't include dos.h and dosfns.h.
8059 * process.c (sys_select):
8060 * msdos.c (sys_select): Accept one more argument and ignore it.
8062 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
8063 adapt data types and code to that.
8066 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
8067 which clashes with the gnulib function of the same name.
8069 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
8071 * font.c (font_style_to_value, font_style_symbolic)
8072 (font_prop_validate_style): Add type checks for values in
8075 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
8077 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
8080 2012-06-29 Eli Zaretskii <eliz@gnu.org>
8082 * xdisp.c (try_window_id): Undo last change.
8084 * w32.c (getwd): Adjust commentary about startup_dir.
8085 (init_environment): Always call sys_access, even in non-MSVC
8086 builds. Don't chdir to the directory of the Emacs executable.
8087 This undoes code from 1997 which was justified by the need to
8088 "avoid conflicts when removing and renaming directories". But its
8089 downside was that every relative file name was being interpreted
8090 relative to the directory of the Emacs executable, which can never
8091 be TRT. In particular, it broke sys_access when called with
8092 relative file names.
8093 (sys_access): Map GetLastError to errno.
8095 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8097 * window.h (struct window): Change type of 'fringes_outside_margins'
8098 to bitfield. Fix comment. Adjust users accordingly.
8099 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
8101 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
8104 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>

8287 Use sprintf return value instead of invoking strlen on result.
8288 In the old days this wasn't portable, since some sprintf
8289 implementations returned char *. But they died out years ago and
8290 Emacs already assumes sprintf returns int.
8291 Similarly for float_to_string.
8292 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

8300 Use sprintf or float_to_string result to avoid need to call strlen.
8301 * data.c (Fnumber_to_string):
8302 Use make_unibyte_string, since the string must be ASCII.
8303 * lisp.h, print.c (float_to_string): Now returns int length.
8304 * term.c (produce_glyphless_glyph):
8305 Use sprintf result rather than recomputing it.
8307 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
8308 * Makefile.in (ALL_CFLAGS):
8309 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

8338 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
8340 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

8343 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
8345 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
8346 instead of truncating it to 63 (admittedly a generous limit).

8406 * keyboard.c (kbd_buffer_get_event):
8407 * process.c (Faccept_process_output):
8408 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
8409 This improves on the previous patch, which introduced a bug
8410 when time_t is unsigned and as wide as intmax_t.
8411 See <http://bugs.gnu.org/9000#51>.
8413 2012-06-23 Eli Zaretskii <eliz@gnu.org>

8476 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
8478 Support higher-resolution time stamps (Bug#9000).
8479 The time stamps are only nanosecond-resolution at the C level,
8480 since that's the best that any real-world system supports now.
8481 But they are picosecond-resolution at the Lisp level, as that's
8482 easy, and leaves room for future OS improvements.
8484 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
8487 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
8488 Don't get current time unless it's needed.
8490 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
8491 now provides it if it's absent.
8492 (start_atimer): Port to higher-res time stamps.
8493 Check for time stamp overflow. Don't get current time more
8494 often than is needed.
8496 * buffer.h (struct buffer): Buffer modtime now has high resolution.
8497 Include systime.h, not time.h.
8498 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
8500 * dired.c: Include stat-time.h.
8501 (Ffile-attributes): File times now have higher resolution.

8504 (struct image): Timestamp now has higher resolution.
8506 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
8507 has at least microseconds now. All uses removed.
8508 (update_frame, update_single_window, update_window, update_frame_1)
8509 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
8510 (duration_to_sec_usec): Remove; no longer needed.
8512 * editfns.c (time_overflow): Now extern.
8513 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
8514 (float-time, Fformat_time_string, Fcurrent_time_string)

8518 (decode_time_components, lisp_seconds_argument): New functions.
8519 (make_time): Now static.
8520 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
8521 Report an error if the time is invalid, rather than having the caller
8524 * fileio.c: Include <stat-time.h>
8525 (Fcopy_file): Copy higher-resolution time stamps.
8526 Prefer to set the time stamp via a file descriptor if that works.
8527 (Fset_file_times, Finsert_file_contents, Fwrite_region)
8528 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
8529 (Fvisited_file_modtime, Fset_visited_file_modtime):
8530 Support higher-resolution time stamps.
8532 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
8534 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
8536 * image.c (prepare_image_for_display, clear_image_cache)
8537 (lookup_image): Port to higer-resolution time stamps.
8539 * keyboard.c (start_polling, bind_polling_period):
8540 Check for time stamp overflow.
8541 (read_char, kbd_buffer_get_event, timer_start_idle)
8542 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
8543 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
8544 Port to higher-resolution time stamps. Do not assume time_t is signed.
8545 (decode_timer): New function. Timers are now vectors of length 9,
8546 not 8, to accommodate the picosecond component.
8547 (timer_check_2): Use it.
8549 * nsterm.m (select_timeout, timeval_subtract): Remove.
8550 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
8551 as they're a bit more accurate and handle overflow better.
8552 (ns_select): Change prototype to be compatible with pselect.
8553 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
8554 * nsterm.h (ns_select): Adjust prototype.
8556 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
8557 us-resolution time stamps.
8558 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
8560 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
8562 * lisp.h (time_overflow): New decl.
8563 (wait_reading_process_output): First arg is now intmax_t, not int,
8564 to accommodate larger waits.
8566 * process.h (struct Lisp_Process.read_output_delay):
8567 Now counts nanoseconds, not microseconds.
8568 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
8570 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
8571 (wait_reading_process_output):
8572 Port to ns-resolution time stamps.
8573 (Faccept_process_output, wait_reading_process_output):
8574 Check for time stamp overflow. Do not assume time_t is signed.
8575 (select_wrapper): Remove; we now use pselect.
8576 (Fprocess_attributes): Now generates ns-resolution time stamps.
8578 * sysdep.c: Include utimens.h. Don't include utime.h
8579 or worry about struct utimbuf; gnulib does that for us now.
8580 (gettimeofday): Remove; gnulib provides a substitute.
8581 (make_timeval): New function.
8582 (set_file_times): Now sets ns-resolution time stamps.
8583 New arg FD; all uses changed.
8584 (time_from_jiffies, ltime_from_jiffies, get_up_time)
8585 (system_process_attributes):
8586 Now returns ns-resolution time stamp. All uses changed.
8587 Check for time stamp overflow.
8589 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
8590 provides a substitute now.
8592 * systime.h: Include timespec.h rather than sys/time.h and time.h,
8593 since it guarantees struct timespec.
8594 (EMACS_TIME): Now struct timespec, so that we can support
8595 ns-resolution time stamps.
8596 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
8597 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
8598 (EMACS_USECS): Remove.
8599 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,

8610 (make_timeval, make_lisp_time, decode_time_components): New decls.
8611 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
8612 that it mishandled time_t overflow. You can't compare by subtracting!
8613 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
8614 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.

8653 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
8654 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,

8693 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
8694 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
8695 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in

8705 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
8706 gets killed during executing of this function (Bug#11665).
8707 Try to always return Qt when the buffer has been actually killed.
8708 (Vkill_buffer_query_functions): In doc-string say that functions
8709 run by this hook should not change the current buffer.
8711 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

8741 * xterm.c (x_draw_underwave): Check for integer overflow.
8742 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

9064 0 items. Allocate new vector from block if vector size is less than
9065 or equal to VBLOCK_BYTES_MAX.
9066 (Fgarbage_collect): Move all vector sweeping code to sweep_vectors.
9067 (init_alloc_once): Add call to init_vectors.
9069 2012-06-08 Stefan Monnier <monnier@iro.umontreal.ca>
9071 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
9073 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
9075 * doprnt.c (doprnt): Truncate multibyte char correctly.
9076 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
9077 would mishandle a string argument "Xc" if X was a multibyte
9078 character of length 2: it would truncate after X's first byte
9079 rather than including all of X.
9081 2012-06-06 Chong Yidong <cyd@gnu.org>
9083 * buffer.c (word_wrap): Doc fix.
9085 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

9103 * xdisp.c (decode_mode_spec_coding): Display a space for a unibyte
9106 2012-06-03 Chong Yidong <cyd@gnu.org>
9108 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
9109 (note_mode_line_or_margin_highlight): If there is no help echo,
9110 use mode-line-default-help-echo. Handle the case where the mouse
9111 position is past the end of the mode line string.
9113 * buffer.c (buffer_local_value_1): New function, split from
9114 Fbuffer_local_value; can return Qunbound.
9115 (Fbuffer_local_value): Use it.
9116 (Vmode_line_format): Docstring tweaks.
9118 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
9120 * sysdep.c (system_process_attributes): Improve comment.
9122 2012-06-02 Stefan Monnier <monnier@iro.umontreal.ca>
9124 * keyboard.c: Export real-this-command to Elisp.
9125 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
9126 and DEFVAR it. Update all users.
9128 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
9130 * minibuf.c (Fassoc_string): Remove duplicate declaration.
9132 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
9133 Convert pctcpu and pctmem to Lisp float properly.
9134 Let the compiler fold better, as 100.0/0x8000 is exact.
9136 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
9138 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
9141 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
9143 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
9145 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
9147 For a 'struct window', replace some Lisp_Object fields to
9148 bitfields where appropriate, remove unused fields.
9149 * window.h (struct window): Remove unused 'last_mark_x' and
9150 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
9151 change its type from Lisp_Object to bitfield.
9152 Change type of 'force_start', 'optional_new_start',
9153 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
9154 fields from Lisp_Object to bitfield. Adjust users accordingly.
9156 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
9158 Pacify gcc -Wdouble-precision when using Xaw.
9159 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
9160 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
9161 Use 'float' consistently, rather than 'float' in most places
9162 and 'double' in a couple of places.
9164 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9166 * xdisp.c (handle_stop): Detect whether we have overlay strings
9167 loaded by testing it->current.overlay_string_index to be
9168 non-negative, instead of checking whether n_overlay_strings is
9169 positive. (Bug#11587)
9171 2012-05-31 Chong Yidong <cyd@gnu.org>
9173 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
9175 * doc.c (Fsubstitute_command_keys): Doc fix.
9177 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9179 * search.c (search_buffer): Remove calls to
9180 r_alloc_inhibit_buffer_relocation, as it is now called by
9181 maybe_unify_char, which was the cause of relocation of buffer text
9184 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9186 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
9187 for the duration of call to load_charset, to avoid problems with
9188 callers of maybe_unify_char that access buffer text through C
9191 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
9192 decrement the inhibition flag, instead of just setting or
9195 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
9197 Remove obsolete '#define static' cruft.
9198 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
9199 This #undef was "temporary" in 2000; it is no longer needed
9200 now that '#define static' has gone away.
9201 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
9202 (gray_bitmap_bits): Remove; no longer needed.
9203 All uses replaced with definiens.
9204 * xterm.c: Include "bitmaps/gray.xbm".
9206 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
9208 Clean up __executable_start, monstartup when --enable-profiling.
9209 The following changes affect the code only when profiling.
9210 * dispnew.c (__executable_start): Rename from safe_bcopy.
9211 Define only on platforms that need it.
9212 * emacs.c: Include <sys/gmon.h> when profiling.
9213 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
9214 (__executable_start): Remove decl, since lisp.h does it now.
9215 (safe_bcopy): Remove decl; no longer has that name.
9216 (main): Coalesce #if into single bit of code, for simplicity.
9217 Cast pointers to uintptr_t, since standard libraries want integers
9219 * lisp.h (__executable_start): New decl.
9221 2012-05-31 Glenn Morris <rgm@gnu.org>
9223 * image.c (Fimagemagick_types): Doc fix.
9225 2012-05-30 Jim Meyering <meyering@redhat.com>
9227 * callproc.c (Fcall_process_region): Include directory component
9228 in mkstemp error message (Bug#11586).

9237 Move to byte-run.el.
9238 (Fautoload): Do the hash-doc more carefully.
9239 * data.c (Fdefalias): Purify definition, except for keymaps.
9240 (Qdefun): Move from eval.c.
9241 * lisp.h (Qdefun): Remove.
9242 * lread.c (read1): Tiny simplification.
9244 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
9246 Do not create empty overlays with the evaporate property (Bug#9642).
9247 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
9248 Bug#9642, but explicitly check that the buffer the overlay would
9249 be moved to is live and rearrange lines to make sure that errors
9250 will not put the overlay in an inconsistent state.
9251 (Fdelete_overlay): Cosmetics.
9253 2012-05-28 Eli Zaretskii <eliz@gnu.org>
9255 * w32term.c (my_bring_window_to_top): New function.
9256 (x_raise_frame): Use handle returned by DeferWindowPos, which
9257 could be different from the original one.
9258 Call my_bring_window_to_top instead of my_set_foreground_window.
9261 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
9262 by calling BringWindowToTop.
9264 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
9265 (WM_EMACS_END): Increase by one.
9267 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
9269 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
9270 This avoids undefined behavior that might cause the eassert
9271 to not catch an out-of-range value.
9273 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
9275 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
9276 Update dependencies.
9278 2012-05-27 Eli Zaretskii <eliz@gnu.org>
9280 * bidi.c (bidi_mirror_char): Fix last change.
9282 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
9284 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
9285 when referring to sectname field in printf format.
9287 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
9289 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
9290 Only r_alloc_inhibit_buffer_relocation needed to be added;
9291 the others were already declared.
9293 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
9294 before checking whether it's out of range. Put the check inside
9296 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
9298 2012-05-27 Ken Brown <kbrown@cornell.edu>
9300 * callproc.c (Fcall_process): Restore a line that was accidentally
9301 commented out in the 2011-02-13 change (bug#11547).
9303 2012-05-27 Eli Zaretskii <eliz@gnu.org>
9305 * lisp.h [REL_ALLOC]: Add prototypes for external functions
9306 defined on ralloc.c.
9308 * buffer.c [REL_ALLOC]: Remove prototypes of
9309 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
9310 they are now on lisp.h.
9312 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
9314 * search.c (search_buffer): Use it to inhibit relocation of buffer
9315 text while re_search_2 is doing its job, because re_search_2 is
9316 passed C pointers to buffer text. (Bug#11519)
9318 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
9321 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
9322 state after an additional call to move_it_in_display_line_to, keep
9323 the values of it->max_ascent and it->max_descent found for the
9325 (pos_visible_p): Revert the comparison against bottom_y to what it
9326 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
9329 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
9331 Fix coding-related core dumps with gcc -ftrapv.
9332 The code was computing A - B, where A and B are pointers, and B is
9333 random garbage. This can lead to core dumps on platforms that
9334 have special pointer registers, and it also leads to core dumps on
9335 x86-64 when compiled with gcc -ftrapv. The fix is to compute
9336 A - B only when B is initialized properly.
9337 * coding.c (coding_set_source, coding_set_destination): Return void.
9338 (coding_change_source, coding_change_destinations): New functions,
9339 with the old behaviors of coding_set_source and coding_set_destination.
9340 All callers that need an offset changed to use these new functions.
9342 2012-05-26 Glenn Morris <rgm@gnu.org>
9344 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
9346 2012-05-26 Eli Zaretskii <eliz@gnu.org>
9348 Extend mouse support on W32 text-mode console.
9349 * xdisp.c (draw_row_with_mouse_face):
9350 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
9352 * w32console.c: Include window.h.
9353 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
9355 (initialize_w32_display): Initialize mouse-highlight data.
9357 * w32inevt.c: Include termchar.h and window.h.
9358 (do_mouse_event): Support mouse-autoselect-window. When the mouse
9359 moves, call note_mouse_highlight. If help_echo changed, call
9360 gen_help_event to produce help-echo message in the echo area.
9361 Call clear_mouse_face if mouse_face_hidden is set in the mouse
9364 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
9366 * lread.c (read1): Simplify slightly to avoid an overflow warning
9367 with GCC 4.7.0 on x86-64.
9369 2012-05-26 Eli Zaretskii <eliz@gnu.org>
9371 * bidi.c (bidi_mirror_char): Revert last change: an int is
9372 definitely wide enough here.
9374 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
9376 Fix integer width and related bugs (Bug#9874).
9377 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
9378 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
9379 (string_bytes, check_sblock, allocate_string_data):
9380 (compact_small_strings, Fmake_bool_vector, make_string)
9381 (make_unibyte_string, make_multibyte_string)
9382 (make_string_from_bytes, make_specified_string)
9383 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
9384 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
9386 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9387 (allocate_pseudovector):
9388 Use int, not EMACS_INT, where int is wide enough.
9389 (inhibit_garbage_collection, Fgarbage_collect):
9390 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9391 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
9392 int might not be wide enough.
9393 (bidi_cache_search, bidi_cache_find, bidi_init_it)
9394 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
9395 (bidi_at_paragraph_end, bidi_find_paragraph_start)
9396 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
9397 (bidi_level_of_next_char, bidi_move_to_visually_next):
9398 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9399 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
9400 (Fkill_buffer, Fset_buffer_major_mode)
9401 (advance_to_char_boundary, Fbuffer_swap_text)
9402 (Fset_buffer_multibyte, overlays_at, overlays_in)
9403 (overlay_touches_p, struct sortvec, record_overlay_string)
9404 (overlay_strings, recenter_overlay_lists)
9405 (adjust_overlays_for_insert, adjust_overlays_for_delete)
9406 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
9407 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
9408 (Foverlay_recenter, last_overlay_modification_hooks_used)
9409 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
9410 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9411 (validate_region): Omit unnecessary test for b <= e,
9412 since that's guaranteed by the previous test.
9413 (adjust_overlays_for_delete): Avoid pos + length overflow.
9414 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
9415 (report_overlay_modification):
9416 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9417 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
9418 Omit pointer cast, which isn't needed anyway, and doesn't work
9419 after the EMACS_INT -> ptrdiff_t change.
9420 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
9421 * buffer.h: Adjust decls to match defn changes elsewhere.
9422 (struct buffer_text, struct buffer):
9423 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9424 Use EMACS_INT, not int, where int might not be wide enough.
9425 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
9426 not int, to avoid needless 32-bit limit on 64-bit hosts.
9427 (exec_byte_code): Use tighter memory-full test, one that checks
9428 for alloca overflow. Don't compute the address of the object just
9429 before an array, as that's not portable. Use EMACS_INT, not
9430 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
9431 * callint.c (Fcall_interactively):
9432 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9433 * callproc.c (call_process_kill, Fcall_process):
9434 Don't assume pid_t fits into an Emacs fixnum.
9435 (call_process_cleanup, Fcall_process, child_setup):
9436 Don't assume pid_t fits into int.
9437 (call_process_cleanup, Fcall_process, delete_temp_file)
9438 (Fcall_process_region):
9439 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9440 (Fcall_process): Simplify handling of volatile integers.
9441 Use int, not EMACS_INT, where int will do.
9442 * casefiddle.c (casify_object, casify_region, operate_on_word)
9443 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
9444 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9445 (casify_object): Avoid integer overflow when overallocating buffer.
9446 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
9447 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
9448 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
9449 * category.h (CATEGORYP): Don't assume arg is nonnegative.
9450 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
9451 integers are now checked earlier. All uses replaced with XINT.
9453 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9454 For CCL_MapSingle, check that content and value are in int range.
9455 (ccl_driver, Fregister_code_conversion_map):
9456 Check that Vcode_version_map_vector is a vector.
9457 (resolve_symbol_ccl_program): Check that vector header is in range.
9458 Always copy the vector, so that we can check its contents reliably
9459 now rather than having to recheck each instruction as it's being
9460 executed. Check that vector words fit in 'int'.
9461 (ccl_get_compiled_code, Fregister_ccl_program)
9462 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
9463 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
9464 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
9465 contents are in range.
9466 (Fccl_execute_on_string): Check that status is in range.
9467 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
9468 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
9469 Accept and return EMACS_INT, not int, because callers can pass values
9471 (c_string_width, strwidth, lisp_string_width, chars_in_text)
9472 (multibyte_chars_in_text, parse_str_as_multibyte)
9473 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
9474 (str_as_unibyte, str_to_unibyte, string_count_byte8)
9475 (string_escape_byte8, Fget_byte):
9476 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
9477 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
9478 avoid mishandling large integers.
9479 * character.h: Adjust decls to match defn changes elsewhere.
9480 * charset.c (load_charset_map_from_file, find_charsets_in_text)
9481 (Ffind_charset_region):
9482 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
9483 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
9484 (load_charset_map_from_vector, Fdefine_charset_internal):
9485 Don't assume fixnum fits in int.
9486 (load_charset_map_from_vector, Fmap_charset_chars):
9487 Remove now-unnecessary CHECK_NATNUMs.
9488 (Fdefine_charset_internal): Check ranges here, more carefully.
9489 Don't rely on undefined behavior with signed left shift overflow.
9490 Don't assume unsigned int fits into fixnum, or that fixnum fits
9491 into unsigned int. Don't require max_code to be a valid fixnum;
9492 that's not true for gb10830 4-byte on a 32-bit host. Allow
9493 invalid_code to be a cons, for the same reason. Require code_offset
9494 to be a character. Avoid int overflow if max_char is close
9496 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
9497 this is intended anyway and avoids some undefined behavior.
9498 (load_charset_map): Pass unsigned, not int, as 2nd arg of
9499 INDEX_TO_CODE_POINT, as that's what it expects.
9500 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
9501 * charset.h (DECODE_CHAR): Return int, not unsigned;
9502 this is what was intended anyway, and it avoids undefined behavior.
9503 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
9504 integer-overflow issues.

10208 * Makefile.in (M_FILE): Remove. All uses removed.
10209 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
10210 * lisp.h (USE_LSB_TAG):
10211 * mem-limits.h (EXCEEDS_LISP_PTR):
10212 Use VAL_MAX, not VALBITS, in #if.
10213 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
10214 (EMACS_UINT): Define unconditionally now.
10215 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
10216 (BITS_PER_EMACS_INT): New constants, replacing
10217 what used to be in config.h, but not useful in #if.
10218 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
10219 define them any more.
10220 (VAL_MAX): New macro.
10222 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
10223 BITS_PER_EMACS_INT, in #if.
10224 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
10225 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
10226 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
10227 * s/ms-w32.h (DATA_START):
10228 Move here from removed file m/intel386.h.
10229 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
10230 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
10232 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
10234 Assume C89 or later.
10235 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
10236 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
10238 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
10239 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
10240 * textprop.c, tparam.c (NULL): Remove.

10247 2012-05-21 Ken Brown <kbrown@cornell.edu>
10249 * xgselect.c (xg_select): Fix first argument in call to 'select'
10252 2012-05-20 Ken Brown <kbrown@cornell.edu>
10254 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
10255 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
10257 2012-05-19 Ken Brown <kbrown@cornell.edu>
10259 * xfns.c (x_in_use): Remove `static' qualifier.
10260 * xterm.h (x_in_use): Declare.
10261 * xgselect.c: Include xterm.h.
10262 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
10263 and `display_arg' (bug#9754).
10265 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
10267 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
10269 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
10270 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
10272 2012-05-18 Eli Zaretskii <eliz@gnu.org>
10274 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
10276 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
10277 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
10279 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
10280 reference to image_cache->refcount.
10281 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
10283 2012-05-17 Juri Linkov <juri@jurta.org>
10285 * search.c (Fword_search_regexp, Fword_search_backward)
10286 (Fword_search_forward, Fword_search_backward_lax)
10287 (Fword_search_forward_lax): Move functions to isearch.el
10288 (bug#10145, bug#11381).
10290 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
10292 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
10294 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
10296 * lread.c (init_obarray): Declare Qt and Qnil as special.
10298 2012-05-14 Glenn Morris <rgm@gnu.org>
10300 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
10301 Put "libexec" before "bin", for the sake of init_callproc_1.
10303 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
10305 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
10307 * unexaix.c: Port to more-recent AIX compilers.
10308 (report_error, report_error_1, make_hdr, copy_sym)
10309 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
10310 Make arguments const char *, not char *, to avoid violations of C
10311 standard and to fix some AIX warnings reported by Gilles Pion.
10313 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10315 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
10316 already have overlays loaded.
10317 (handle_single_display_spec): Before returning without displaying
10318 fringe bitmap, synchronize the bidi iterator with the main display
10319 iterator, by calling iterate_out_of_display_property.
10320 (iterate_out_of_display_property): Detect buffer iteration by
10321 testing that it->string is a Lisp string.
10322 (get_next_display_element): When the current object is exhausted,
10323 and there's something on it->stack, call set_iterator_to_next to
10324 proceed with what's on the stack, instead of returning zero.
10325 (set_iterator_to_next): If called at the end of a Lisp string,
10326 proceed to consider_string_end without incrementing string
10327 position. Don't increment display vector index past the end of
10328 the display vector. (Bug#11417)
10329 (pos_visible_p): Don't report a position visible when move_it_to
10330 stopped at the last line of window, which happens to be scanned
10331 backwards by the bidi iteration. (Bug#11464)
10333 2012-05-14 Eli Zaretskii <eliz@gnu.org>
10335 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
10336 and right-margin display specs even if the spec is invalid or we
10337 are on a TTY, and thus unable to display on the fringes.
10338 That's because the text with the property will not be displayed anyway,
10339 so we need to signal to the caller that this is a "replacing"
10340 display spec. This fixes display when the spec is invalid or we
10343 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
10345 * unexaix.c (make_hdr): Fix typo in prototype.
10346 This bug broke the build on AIX. Problem reported by Gilles Pion.
10348 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
10350 * keyboard.c (kbd_buffer_get_event): Read special events also in
10351 batch mode. (Bug#11415)
10353 2012-05-12 Glenn Morris <rgm@gnu.org>
10355 * ns.mk: Update for ns_appbindir no longer having trailing "/".
10357 2012-05-12 Eli Zaretskii <eliz@gnu.org>
10359 * lisp.mk (lisp): Add newcomment.elc.
10361 2012-05-12 Glenn Morris <rgm@gnu.org>
10363 * Makefile.in (MKDIR_P): New, set by configure.
10364 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
10366 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
10368 Remove unused function hourglass_started.
10369 * dispextern.h (hourglass_started):
10370 * w32fns.c (hourglass_started):
10371 * xdisp.c (hourglass_started): Remove.
10373 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
10375 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
10376 Update dependencies.
10378 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
10380 * xgselect.c (xg_select): Put maxfds+1 into a var.
10381 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
10383 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
10385 2012-05-10 Dave Abrahams <dave@boostpro.com>
10387 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
10388 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
10390 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
10392 * dbusbind.c (xd_registered_buses): New internal Lisp object.
10393 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
10394 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
10395 Initialize xd_registered_buses.
10397 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
10399 Untag more efficiently if USE_LSB_TAG.
10400 This is based on a proposal by YAMAMOTO Mitsuharu in
10401 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
10402 For an admittedly artificial (nth 8000 longlist) benchmark on
10403 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
10404 Emacs's overall text size by 1%.
10405 * lisp.h (XUNTAG): New macro.
10406 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
10407 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
10408 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
10409 * eval.c (Fautoload):
10410 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
10411 * frame.h (XFRAME): Use XUNTAG.
10413 Port recent dbusbind.c changes to 32-bit --with-wide-int.
10414 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
10415 Remove unportable assumptions about print widths of types like
10417 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
10418 intptr_t when converting between pointer and integer, to avoid GCC
10419 warnings about wrong width.
10421 2012-05-09 Eli Zaretskii <eliz@gnu.org>
10423 * w32proc.c (new_child): Force Windows to reserve only 64KB of
10424 stack for each reader_thread, instead of defaulting to 8MB
10425 determined by the linker. This avoids failures in creating
10426 subprocesses on Windows 7, see the discussion in this thread:
10427 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
10429 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
10431 Fix up display of the *Minibuf-0* buffer in the mini window.
10432 * keyboard.c (read_char): Don't clear the echo area if there's no
10434 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
10435 contents of *Minibuf-0*) if there's no message displayed in its stead.
10437 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
10439 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
10442 2012-05-06 Chong Yidong <cyd@gnu.org>
10444 * lisp.mk (lisp): Update.
10446 2012-05-05 Jim Meyering <meyering@redhat.com>
10448 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
10450 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
10452 * data.c (PUT_ERROR): New macro.
10453 (syms_of_data): Use it. Add new error type `user-error'.
10454 * undo.c (user_error): New function.
10455 (Fprimitive_undo): Use it.
10456 * print.c (print_error_message): Adjust print style for `user-error'.
10457 * keyboard.c (user_error): New function.
10458 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
10460 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
10462 Do not limit current-time-string to years 1000..9999.
10463 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
10464 (Fcurrent_time_string): Support any year that is supported by the
10465 underlying localtime representation. Don't use asctime, as it
10466 has undefined behavior for years outside the range -999..9999.
10468 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
10470 Fix race conditions involving setenv, gmtime, localtime, asctime.
10471 Without this fix, interrupts could mess up code that uses these
10472 nonreentrant functions, since setting TZ invalidates existing
10473 tm_zone or tzname values, and since most of these functions return
10474 pointers to static storage.
10475 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
10476 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
10477 Grow the critical sections to include not just invoking
10478 localtime/gmtime, but also accessing these functions' results
10479 including their tm_zone values if any, and any related TZ setting.
10480 (format_time_string): Last arg is now struct tm *, not struct tm **,
10481 so that the struct tm is saved in the critical section.
10482 All callers changed. Simplify allocation of initial buffer, partly
10483 motivated by the fact that memory allocation needs to be outside
10484 the critical section.
10486 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
10488 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
10489 with RESET_INTERVAL.
10491 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
10492 Remove duplicated buffer name initialization.
10494 2012-05-02 Jim Meyering <jim@meyering.net>
10496 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
10498 * xfns.c (x_window): Use xstrdup (Bug#11375).
10500 2012-05-02 Eli Zaretskii <eliz@gnu.org>
10502 * xdisp.c (pos_visible_p): If already at a newline from the
10503 display string before the 'while' loop, don't walk back the glyphs
10504 from it3.glyph_row. Solves assertion violation when the display
10505 string begins with a newline (egg.el). (Bug#11367)
10507 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
10509 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
10512 2012-05-01 Glenn Morris <rgm@gnu.org>
10514 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
10515 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
10516 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
10517 All were removed before 23.1.
10519 * dispnew.c: Remove HAVE_LIBNCURSES test;
10520 it is always true on relevant platforms.
10522 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
10523 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
10525 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
10527 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
10529 * .gdbinit (xpr): Remove checks for no longer existing misc types.
10530 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
10533 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
10535 Do not avoid creating empty evaporating overlays (Bug#9642).
10536 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
10537 That is, do not delete an evaporating overlay if it becomes
10538 empty after its bounds are adjusted to fit within its buffer.
10539 This fix caused other problems, and I'm reverting it until we get
10540 to the bottom of them.
10542 2012-04-27 Chong Yidong <cyd@gnu.org>
10544 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
10546 2012-04-27 Eli Zaretskii <eliz@gnu.org>
10548 * xdisp.c (pos_visible_p): If the window start position is beyond
10549 ZV, start the display from buffer beginning. Prevents assertion
10550 violation in init_iterator when the minibuffer window is scrolled
10551 via the scroll bar.
10553 * window.c (window_scroll_pixel_based): Likewise.
10555 2012-04-27 Chong Yidong <cyd@gnu.org>
10557 * keymap.c (where_is_internal): Doc fix (Bug#10872).
10559 2012-04-27 Glenn Morris <rgm@gnu.org>
10561 * fileio.c (Fcopy_file, Fset_file_selinux_context):
10562 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
10564 2012-04-27 Eli Zaretskii <eliz@gnu.org>
10566 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
10567 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
10569 2012-04-26 Eli Zaretskii <eliz@gnu.org>
10571 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
10572 display element, check also the underlying string or buffer
10573 character. (Bug#11341)
10575 * w32menu.c: Include w32heap.h.
10576 (add_menu_item): If the call to AppendMenuW (via
10577 unicode_append_menu) fails, disable Unicode menus only if we are
10578 running on Windows 9X/Me.
10580 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
10582 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
10583 (xgetint): Add missing shift for LSB tags.
10585 2012-04-24 Martin Rudalics <rudalics@gmx.at>
10587 * keyboard.c (read_char): Don't wipe echo area for select window
10588 events: These might get delayed via `mouse-autoselect-window'
10591 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
10593 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
10594 manipulation of :loaded-from data.
10596 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
10598 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
10599 now a cons (bug#11311).
10601 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
10603 Do not create empty overlays with the evaporate property (Bug#9642).
10604 * buffer.c (Fmove_overlay): Delete an evaporating overlay
10605 if it becomes empty after its bounds are adjusted to fit within
10606 its buffer. Without this fix, in a nonempty buffer (let ((o
10607 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
10608 yields an empty overlay that has the evaporate property, which is
10609 not supposed to happen.
10611 Fix minor GTK3 problems found by static checking.
10612 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
10613 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
10614 (struct _EmacsFixedClass, emacs_fixed_get_type):
10615 Move decls here from emacsgtkfixed.h, since they needn't be public.
10616 (emacs_fixed_get_type): Now static.
10617 (emacs_fixed_class_init): Omit unused local.
10618 (emacs_fixed_child_type): Remove; unused.
10619 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
10620 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
10621 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
10622 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
10623 (EMACS_FIXED_GET_CLASS): Remove; unused.
10624 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
10626 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
10627 Problem reported by Juanma Barranquero for Windows -Wunused-function.
10629 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
10631 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
10632 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
10633 (__malloc_size_t, __malloc_ptrdiff_t):
10634 Remove. All uses removed, replaced by the definiens if needed,
10635 since we can assume C89 or better now.
10636 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
10637 (protect_malloc_state, align, get_contiguous_space)
10638 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

10724 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
10726 * sysdep.c [__FreeBSD__]: Minor cleanups.
10727 (list_system_processes, system_process_attributes) [__FreeBSD__]:
10728 Use Emacs indenting style more consistently. Avoid some casts.

10812 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
10813 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
10814 (NEED_MEM_INSERT): New macro.
10815 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
10816 Remove one incorrect comment and fix another.

10852 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
10853 * s/netbsd.h, s/sol2-6.h:
10854 Remove definition of GC_MARK_STACK, since the default now works.
10855 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:

10883 2012-04-11 Daniel Colascione <dancol@dancol.org>
10885 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
10886 against is gone. It's better to use vfork now so that when Cygwin
10887 gains a new, working vfork, we use it automatically (bug#10398).
10889 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

10910 being loaded (bug#10424).
10912 2012-04-09 Glenn Morris <rgm@gnu.org>
10914 * doc.c (Fsnarf_documentation): Check variables, functions are bound,

10942 * minibuf.c (Fread_variable): Callers changed.
10944 2012-04-09 Eli Zaretskii <eliz@gnu.org>
10946 * xdisp.c (set_cursor_from_row): If the display string appears in
10947 the buffer at position that is closer to point than the position
10948 after the display string, display the cursor on the first glyph of
10949 the display string. Fixes cursor display when a 'display' text
10950 property immediately follows invisible text. (Bug#11094)
10952 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
10954 composite.c: use 'double' consistently
10955 * composite.c (get_composition_id): Use 'double' consistently
10956 instead of converting 'float' to 'double' and vice versa; this is
10957 easier to understand and avoids a GCC warning.
10959 2012-04-09 Glenn Morris <rgm@gnu.org>
10961 * Makefile.in: Generate leim-list with bootstrap-emacs, in

11006 [!WINDOWSNT]: New macros.
11007 (init_libxml2_functions, libxml2_loaded_p): New functions.
11008 (parse_region): Call fn_xmlCheckVersion instead of using the macro

11011 Calls xmlCleanupParser only if libxml2 was loaded (or statically
11013 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
11014 Call init_libxml2_functions before calling libxml2 functions.
11015 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
11017 * emacs.c: Don't include libxml/parser.h.

11019 xmlCleanupParser directly.
11021 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
11023 2012-04-07 Eli Zaretskii <eliz@gnu.org>
11025 * indent.c (Fvertical_motion): If there is a display string at
11026 point, use it.vpos to compute how many lines to backtrack after
11027 move_it_to point. (Bug#11133)
11029 2012-04-06 Eli Zaretskii <eliz@gnu.org>
11031 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
11032 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
11033 about subtle differences between FETCH_CHAR* and STRING_CHAR*
11034 macros related to unification of CJK characters. For the details,
11035 see the discussion following the message here:
11036 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.

11052 2012-03-31 Eli Zaretskii <eliz@gnu.org>
11054 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
11055 position we get to after a call to move_it_to fails the
11056 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
11057 only if we wind up in a string from display property. (Bug#11063)
11059 * window.c (Fdelete_other_windows_internal): Invalidate the row
11060 and column information about mouse highlight, so that redisplay
11061 restores it after reallocating the glyph matrices. (Bug#7464)
11063 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
11064 string comes from a `display' text property, use the buffer
11065 position of that property as if we actually saw that position in
11067 (move_it_by_lines): Remove the assertion that
11068 "it->current_x == 0 && it->hpos == 0" which can be legitimately
11069 violated when there's a before-string at the beginning of a line.
11072 2012-03-30 Eli Zaretskii <eliz@gnu.org>
11074 * xdisp.c (append_space_for_newline): If the default face was

11077 extending the face to the end of the line.
11078 (display_line): Call extend_face_to_end_of_line when the default
11079 face was remapped. (Bug#11068)

11101 * keyboard.c (Vselection_inhibit_update_commands): New variable.
11102 (command_loop_1): Use it; inhibit selection update for
11103 handle-select-window too (Bug#8996).
11105 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
11107 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
11109 2012-03-25 Kenichi Handa <handa@m17n.org>
11111 * dispextern.h (struct glyph): Change the bit length of
11112 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
11114 2012-03-24 Eli Zaretskii <eliz@gnu.org>
11116 * s/ms-w32.h (tzname): Include time.h before redirecting to
11117 _tzname. Fixes the MSVC build. (Bug#9960)
11119 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
11121 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
11124 * xterm.c (XTread_socket): Only modify handling_signal if
11125 !SYNC_INPUT. (Bug#11080)
11127 2012-03-23 Eli Zaretskii <eliz@gnu.org>
11129 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
11130 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
11131 when fetching a multibyte character consumes more bytes than
11132 CHAR_BYTES returns, due to unification of CJK characters in
11133 string_char. (Bug#11073)
11135 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
11137 * process.c (wait_reading_process_output): Handle pty disconnect
11138 by refraining from sending oneself a SIGCHLD (bug#10933).

11162 to reflect default non-nil value of redisplay-dont-pause.
11164 2012-03-19 Kenichi Handa <handa@m17n.org>
11166 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
11167 it fit in a valid range (Bug#11003).
11169 2012-03-18 Eli Zaretskii <eliz@gnu.org>
11171 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
11172 that is not from display property, accept the row as a "cursor
11173 row" if one of the string's character has a non-nil `cursor'
11174 property. Fixes cursor positioning when there are newlines in
11175 overlay strings, e.g. in icomplete.el. (Bug#11035)
11177 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
11179 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
11181 2012-03-12 Chong Yidong <cyd@gnu.org>
11183 * eval.c (inhibit_lisp_code): Rename from
11184 inhibit_window_configuration_change_hook; move from window.c.
11186 * xfns.c (unwind_create_frame_1, Fx_create_frame):
11187 * window.c (run_window_configuration_change_hook)
11188 (syms_of_window): Callers changed.

11208 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
11211 2012-03-03 Glenn Morris <rgm@gnu.org>
11213 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
11215 2012-03-02 Eli Zaretskii <eliz@gnu.org>
11217 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
11218 position past the first glyph_row that ends at ZV. (Bug#10902)
11219 (redisplay_window, next_element_from_string): Fix typos in
11221 (redisplay_window): Pass to move_it_vertically the margin in
11222 pixels, not in screen lines.
11224 2012-03-02 Glenn Morris <rgm@gnu.org>
11226 * buffer.c (buffer-list-update-hook): Doc fix.
11228 2012-02-29 Eli Zaretskii <eliz@gnu.org>
11230 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
11231 push_it before setting up the iterator for the first overlay
11232 string, even if we have an empty string loaded.
11233 (next_overlay_string): If there's an empty string on the iterator
11234 stack, pop the stack. (Bug#10903)
11236 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
11238 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
11239 Suggested by Stefan Monnier in
11240 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
11241 * alloc.c (widen_to_Lisp_Object): New static function.
11242 (mark_memory): Also mark Lisp_Objects by fetching pointer words
11243 and widening them to Lisp_Objects. This would work even if
11244 USE_LSB_TAG is defined and wide integers are used, which might
11245 happen in a future version of Emacs.
11247 2012-02-25 Chong Yidong <cyd@gnu.org>
11249 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
11252 * xselect.c (Fx_selection_exists_p): Doc fix.

11254 before saving to clipboard manager.
11256 2012-02-24 Chong Yidong <cyd@gnu.org>
11258 * keyboard.c (process_special_events): Handle all X selection
11259 requests in kbd_buffer, not just the next one (Bug#8869).
11261 2012-02-23 Chong Yidong <cyd@gnu.org>
11263 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
11264 call when setting menu-bar-lines and tool-bar-lines parameters.
11265 (unwind_create_frame_1): New helper function.

11278 * fileio.c (Vfile_name_handler_alist): Doc fix.
11280 * buffer.c (Fget_file_buffer): Protect against invalid file
11281 handler return value.
11283 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
11285 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
11286 when computing $valmask.
11288 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
11289 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
11290 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
11291 It's useless in that case, and it can cause problems on hosts
11292 that allocate halves of EMACS_INT values separately.
11293 Reported by Dan Horák. Diagnosed by Andreas Schwab in
11294 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
11295 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
11296 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
11297 it avoids undefined behavior on hosts where shifting right by more
11298 than the word width has undefined behavior.
11300 2012-02-19 Chong Yidong <cyd@gnu.org>
11302 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
11303 (Funhandled_file_name_directory, Ffile_name_as_directory)
11304 (Fdirectory_file_name, Fexpand_file_name)
11305 (Fsubstitute_in_file_name): Protect against invalid file handler
11306 return values (Bug#10845).
11308 2012-02-18 Eli Zaretskii <eliz@gnu.org>

11320 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
11322 2012-02-15 Chong Yidong <cyd@gnu.org>
11324 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
11325 marked as special. Also, starting docstrings with * is obsolete.

11340 2012-02-12 Chong Yidong <cyd@gnu.org>
11342 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
11343 as that creates a dangerous corner case.
11345 * window.c (Fdelete_window_internal): Invalidate the mouse
11346 highlight (Bug#9904).
11348 2012-02-12 Glenn Morris <rgm@gnu.org>

11353 * nsselect.m (Fx_own_selection_internal)
11354 (Fx_disown_selection_internal, Fx_selection_exists_p)
11355 (Fx_selection_owner_p, Fx_get_selection_internal):
11356 Sync docs and argument specs with the xselect.c versions.
11358 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>

11378 2012-02-07 Chong Yidong <cyd@gnu.org>
11380 * buffer.c (Fbuffer_local_variables)
11381 (buffer_lisp_local_variables): Handle unbound vars correctly;
11382 don't let Qunbound leak into Lisp.
11384 2012-02-07 Glenn Morris <rgm@gnu.org>
11386 * image.c (Fimagemagick_types): Doc fix.
11388 * image.c (imagemagick-render-type): Change it from a lisp object
11389 to an integer. Move the doc here from the lisp manual.

11419 before BEGV. (Bug#10696)
11421 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
11423 Handle overflow when computing char display width (Bug#9496).
11424 * character.c (char_width): Return EMACS_INT, not int.
11425 (char_width, c_string_width): Check for overflow when
11426 computing the width; this is possible now that individual
11427 characters can have unbounded width. Problem introduced
11428 by merge from Emacs 23 on 2012-01-19.
11430 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

11452 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
11454 (x_produce_glyphs): If the component of a composition is a null
11455 string, set it->pixel_width to 1 to avoid zero-width glyph.
11457 2012-02-01 Eli Zaretskii <eliz@gnu.org>
11459 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
11460 first 2 arguments are identical. This makes inserting large
11461 output from a subprocess an order of magnitude faster on
11462 MS-Windows, where all sbrk'ed memory is always contiguous.
11464 2012-01-31 Glenn Morris <rgm@gnu.org>

11547 2012-01-11 Glenn Morris <rgm@gnu.org>
11549 * lread.c (init_lread): If no-site-lisp, remove site-lisp dirs

11557 Update template values to be closer to their typical values these days.
11559 2012-01-09 Eli Zaretskii <eliz@gnu.org>
11561 * xdisp.c (rows_from_pos_range): Accept additional argument
11562 DISP_STRING, and accept any glyph in a row whose object is that
11563 string as eligible for mouse highlight. Fixes mouse highlight of
11564 display strings from overlays. (Bug#10464)
11566 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>

12077 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
12078 Otherwise, valgrind does not work on some platforms.
12079 Problem reported by Andreas Schwab in
12080 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
12081 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
12082 is set, removing the need for VIRT_ADDRESS_VARIES.
12083 (PURE_P): Use a more-efficient implementation that needs just one
12084 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
12085 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
12086 to 4 (xorl, subq, cmpq, setbe).
12087 * alloc.c (pure): Always extern now, since that's the
12088 VIRT_ADDR_VARIES behavior.
12089 (PURE_POINTER_P): Use a single comparison, not two, for
12090 consistency with the new puresize.h.
12091 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
12092 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

12098 (erase_phys_cursor, update_window_cursor, show_mouse_face)
12099 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
12100 behave as if the cursor position were at the window margin.
12102 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
12103 and the cursor position is out of bounds, behave as if the cursor
12104 position were at the window margin. (Bug#10075)
12106 2011-11-18 Chong Yidong <cyd@gnu.org>
12108 * window.c (Fwindow_combination_limit): Make first argument

12127 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
12129 * xdisp.c (row_hash): New function, body extracted from
12130 compute_line_metrics.
12131 (compute_line_metrics): Call row_hash, instead of computing the
12134 * dispnew.c (verify_row_hash): Call row_hash for computing the
12135 hash code of a row, instead of duplicating code from xdisp.c.
12137 * dispextern.h (row_hash): Add prototype.
12139 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

12175 2011-11-14 Eli Zaretskii <eliz@gnu.org>
12177 * xdisp.c (display_line): Move the call to
12178 highlight_trailing_whitespace before the call to
12179 compute_line_metrics, since the latter needs to see the final
12180 faces of all the glyphs to compute ROW's hash value.
12181 Fixes assertion violations in row_equal_p. (Bug#10035)
12183 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
12185 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
12186 just return (bug#10044).
12188 2011-11-12 Eli Zaretskii <eliz@gnu.org>
12190 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
12191 with user-defined heap size. Bump the default size of the temacs
12192 heap to 27MB, to avoid memory warning when running temacs.
12193 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
12195 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
12196 current_matrix and desired_matrix. (Bug#9990)
12197 (verify_row_hash) [XASSERTS]: New function.

12244 Avoid some portability problems by eschewing 'extern inline' functions.
12245 The trivial performance wins aren't worth the portability hassles; see
12246 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
12248 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

12314 * xmenu.c (cleanup_widget_value_tree): New function.
12315 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

12322 (window_box_width, window_box_left, window_box_left_offset)
12323 (window_box_right, window_box_right_offset): Declare extern.
12324 Otherwise, these inline functions do not conform to C99 and
12325 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
12326 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
12327 * intervals.c (adjust_intervals_for_insertion)

12330 (static_offset_intervals): Remove.
12331 (offset_intervals): Rewrite using the old contents of
12332 static_offset_intervals. The old version didn't conform to C99
12333 because an extern inline function contained a reference to an

12492 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
12494 * xterm.c: Declare x_handle_net_wm_state to return int.
12495 (handle_one_xevent): Check if we are iconified but don't have
12496 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
12497 (get_current_wm_state): Return non-zero if not hidden,
12498 check for _NET_WM_STATE_HIDDEN (Bug#9893).
12499 (do_ewmh_fullscreen): Ignore return value from get_current_wm_state.
12500 (x_handle_net_wm_state): Return what get_current_wm_state returns.
12501 (x_term_init): Initialize dpyinfo->Xatom_net_wm_state_hidden.
12503 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
12505 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
12506 so that this new function doesn't get optimized away by a
12507 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
12509 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
12511 * frame.h (MOUSE_HL_INFO): Remove excess parens.
12513 2011-10-29 Eli Zaretskii <eliz@gnu.org>
12515 Fix the `xbytecode' command.
12516 * .gdbinit (xprintbytestr): New command.
12517 (xwhichsymbols): Rename from `which'; all callers changed.
12518 (xbytecode): Print the byte-code string as well.
12520 2011-10-29 Kim Storm <storm@cua.dk>
12522 * alloc.c (which_symbols): New function.
12524 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
12526 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
12529 2011-10-29 Glenn Morris <rgm@gnu.org>
12531 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
12532 Not clear what it was for, and it causes various bugs. (Bug#9839)
12534 2011-10-28 Eli Zaretskii <eliz@gnu.org>
12536 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
12537 possible random value that matches one of those tested as
12538 condition to clear the mouse face.
12540 2011-10-28 Chong Yidong <cyd@gnu.org>
12542 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
12544 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
12546 * window.c (make_window): Initialize phys_cursor_on_p.
12548 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
12550 * lisp.h (struct Lisp_Symbol): Update comments.
12552 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
12554 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
12556 2011-10-28 Eli Zaretskii <eliz@gnu.org>
12558 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
12559 <oslsachem@gmail.com> for helping to debug this.
12561 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
12562 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
12563 (g_b_init_get_glyph_outline_w): New static variables.
12564 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
12565 (GetGlyphOutlineW_Proc): New typedefs.
12566 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
12567 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
12569 (w32font_open_internal, compute_metrics):
12570 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
12571 instead of calling the "wide" APIs directly.
12573 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
12575 * w32.h (syms_of_w32font): Add prototype.
12577 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
12579 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
12580 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
12581 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
12582 (Fmove_to_window_line): Doc fix.
12584 2011-10-27 Chong Yidong <cyd@gnu.org>
12586 * process.c (make_process): Set gnutls_state to NULL.
12588 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
12589 non-NULL, regardless of GNUTLS_INITSTAGE.
12590 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
12591 an error. Set process slots as soon as we allocate them.
12593 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
12595 2011-10-27 Chong Yidong <cyd@gnu.org>
12597 * gnutls.c (emacs_gnutls_deinit): New function.
12598 Deallocate credentials structures as well as calling gnutls_deinit.
12599 (Fgnutls_deinit, Fgnutls_boot): Use it.
12601 * process.c (make_process): Initialize GnuTLS credentials to NULL.
12602 (deactivate_process): Call emacs_gnutls_deinit.
12604 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
12606 * image.c (x_create_x_image_and_pixmap):
12607 * w32.c (sys_rename, w32_delayed_load):
12608 * w32font.c (fill_in_logfont):
12609 * w32reg.c (x_get_string_resource): Silence compiler warnings.
12611 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
12613 * w32fns.c (w32_default_color_map): New function,
12614 extracted from Fw32_default_color_map.
12615 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
12617 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
12619 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
12621 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
12623 * keyboard.c (test_undefined): New function (bug#9751).
12624 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
12626 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
12628 * sysdep.c (init_sys_modes): Fix the check for the controlling
12629 terminal (Bug#6649).
12631 2011-10-20 Eli Zaretskii <eliz@gnu.org>
12633 * dispextern.h (struct bidi_it): New member next_en_type.
12635 * bidi.c (bidi_line_init): Initialize the next_en_type member.
12636 (bidi_resolve_explicit_1): When next_en_pos is valid for the
12637 current character, check also for next_en_type being WEAK_EN.
12638 (bidi_resolve_weak): Don't enter the expensive loop if the current
12639 position is before next_en_pos. Record the bidi type of the first
12640 non-ET, non-BN character we find, in addition to its position.
12641 (bidi_level_of_next_char): Invalidate next_en_type when
12642 next_en_pos is over-stepped.
12644 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
12646 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
12647 * editfns.c: Rewrite current-time-zone so that it invokes
12648 the equivalent of (format-time-string "%Z") to get the time zone name.
12649 This fixes a bug when the time zone name contains characters that
12650 need converting from the system time locale to Emacs internal format.
12651 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
12652 that patch fixed format-time-string to do the conversion, but
12653 I forgot to fix current-time-zone.
12654 (format_time_string): New function, containing most of
12655 what Fformat_time_string used to contain.
12656 (Fformat_time_string): Rewrite in terms of format_time_string.
12657 This doesn't change this function's behavior.
12658 (current-time-zone): Rewrite to use format_time_string.
12659 This fixes the bug reported by Michael Schierl in
12660 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
12661 Jason Rumney's 2007-06-07 change worked around this bug, but
12663 * systime.h (tzname, timezone): Remove no-longer-used declarations.
12665 2011-10-19 Eli Zaretskii <eliz@gnu.org>
12667 * xdisp.c (start_display): If the character at POS is displayed
12668 via a display vector, reset IT->current.dpvec_index to zero.
12669 (try_window_reusing_current_matrix): If a line ends in a display
12670 vector or the next line starts in a display vector, continue
12671 redrawing the window even though the character position of
12672 start_row was reached.
12675 2011-10-18 Chong Yidong <cyd@gnu.org>
12677 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
12678 with nobreak-char-display too.
12680 2011-10-18 Eli Zaretskii <eliz@gnu.org>
12682 Fix part 3 of bug#9771.
12683 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
12684 (bidi_resolve_neutral): Don't enter the expensive loop looking for
12685 non-neutral characters if the current character is a paragraph
12686 separator (a.k.a. Newline). This avoids running the same
12687 expensive loop twice, once when we consume the preceding newline
12688 and the other time when the line actually needs to be displayed.
12689 Avoid the loop when we see neutrals on the base embedding level
12690 following a character whose directionality is the same as the
12691 paragraph's. This avoids running the expensive loop when a line
12692 ends in a long sequence of neutrals, like control characters.
12693 Add assertion against STRONG_AL type. Slightly rearrange code
12694 that determines the type of a neutral given the first non-neutral
12696 (bidi_level_of_next_char): Set next_en_pos to zero when
12697 invalidating its info.
12699 2011-10-17 Eli Zaretskii <eliz@gnu.org>
12701 * xdisp.c (push_display_prop): Determine whether to record string
12702 or buffer position by IT->string, not by IT->method. Allow
12703 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
12704 (move_it_vertically_backward): Don't look for character position
12705 immediately after the newline when in a continuation line.
12708 2011-10-15 Martin Rudalics <rudalics@gmx.at>
12710 * window.c (coordinates_in_window): Rewrite and delabelize
12711 vertical border check. (Bug#5357) (Bug#9618)
12713 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
12715 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
12716 errors in XSetWindowBorder (bug#9310).
12718 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
12720 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
12721 avoid crash when xmalloc overrun checking is enabled.
12723 2011-10-13 Eli Zaretskii <eliz@gnu.org>
12725 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
12726 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
12727 cursor motion with <left> and <right> arrow keys.
12729 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
12730 some callers set that themselves.
12732 2011-10-12 Eli Zaretskii <eliz@gnu.org>
12734 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
12735 display string and the previous row comes from the same string and
12736 is empty. (Bug#9739) (Bug#9738)
12738 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
12740 * doc.c (get_doc_string): Encode file name (bug#9735).
12742 2011-10-12 Eli Zaretskii <eliz@gnu.org>
12744 * bidi.c (bidi_level_of_next_char):
12745 * xdisp.c (get_visually_first_element): Remove old incorrect
12746 comments regarding the Unicode Line Separator character.
12748 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
12750 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
12752 * alloc.c (Fgc_status): Do not access beyond zombies array
12753 boundary if nzombies > MAX_ZOMBIES.
12754 * alloc.c (dump_zombies): Add missing format specifier.
12756 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
12758 * xdisp.c (set_cursor_from_row): Simplify conditionals,
12759 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
12761 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
12762 Some packages use them to denote characters with modifiers.
12764 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
12766 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
12767 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
12768 matching a pp-number. Rename parameter var to var1.
12770 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
12772 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
12774 2011-10-08 Glenn Morris <rgm@gnu.org>
12776 * callint.c (Fcall_interactively): Give a more explicit error for the
12777 'c' case with a non-character input. (Bug#8479)
12779 2011-10-08 Eli Zaretskii <eliz@gnu.org>
12781 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
12783 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
12784 lines that are hscrolled on the left.
12786 * dispnew.c (buffer_posn_from_coords): Account for a possible
12787 presence of header-line. (Bug#4426)
12789 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
12791 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
12792 Don't advertise functionality which we discourage or doesn't work.
12794 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
12796 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
12797 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
12798 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
12799 this makes Emacs dump core during garbage collection on rare
12800 occasions. sizeof is obviously inferior to offsetof here, so
12801 stick with offsetof.
12802 (GC_POINTER_ALIGNMENT): New macro.
12803 (mark_memory): Omit 3rd (offset) arg; caller changed.
12804 Don't assume EMACS_INT alignment is the same as pointer alignment.
12806 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
12808 * keyboard.c (read_key_sequence_remapped): New var.
12809 (read_key_sequence): Compute remapping in the right buffer.
12810 (command_loop_1): Use read_key_sequence's remapping directly.
12812 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
12814 * dired.c (file_name_completion): Don't expand file name.
12815 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
12816 before checking file name handler.
12818 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
12819 they've been requested explicitly (bug#9591).
12821 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
12823 * keymap.c (Fsingle_key_description): Use make_specified_string
12824 instead of build_string to build string from push_key_description.
12827 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
12829 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
12830 This fixes a Y2038 bug on 64-bit hosts.
12831 * buffer.c (reset_buffer):
12832 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
12833 (Fclear_buffer_auto_save_failure):
12834 Use 0, not -1, to represent an unset failure time, since time_t
12835 might not be signed.
12837 Remove dependency on glibc malloc internals.
12838 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12839 Move back here from lisp.h, but with their new implementations.
12840 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
12841 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
12842 * charset.c (charset_table_init): New static var.
12843 (syms_of_charset): Use it instead of xmalloc. This removes a
12844 dependency on glibc malloc internals. See Eli Zaretskii's comment in
12845 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
12846 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12847 Move back to alloc.c.
12848 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
12849 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
12851 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
12853 * nsterm.m (windowDidResize): Call x_set_window_size only when
12854 ns_in_resize is true. Otherwise set pixelwidth/height and
12855 call change_frame_size (Bug#9628).
12857 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
12859 Port --enable-checking=all to Fedora 14 x86-64.
12860 * charset.c (syms_of_charset): Also account for glibc malloc's
12861 internal overhead when calculating the initial malloc maximum.
12863 Port --enable-checking=all to Fedora 14 x86.
12864 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12866 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
12867 (overrun_check_realloc, overrun_check_free):
12868 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
12869 That way, xmalloc returns a properly-aligned pointer even if
12870 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
12871 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
12872 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
12873 into account when calculating the initial malloc maximum.
12874 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12875 Move here from alloc.c, so that charset.c can use it too.
12876 Properly align; the old code wasn't right for common 32-bit hosts
12877 when configured with --enable-checking=all.
12878 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
12879 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
12881 2011-09-29 Eli Zaretskii <eliz@gnu.org>
12883 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
12886 2011-09-28 Eli Zaretskii <eliz@gnu.org>
12888 * xdisp.c (compute_display_string_end): If there's no display
12889 string at CHARPOS, return -1.
12891 * bidi.c (bidi_fetch_char): When compute_display_string_end
12892 returns a negative value, treat the character as a normal
12893 character not covered by a display string. (Bug#9624)
12895 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
12897 * lread.c (Fread_from_string): Fix typo in docstring.
12899 2011-09-27 Eli Zaretskii <eliz@gnu.org>
12901 * xdisp.c (handle_invisible_prop): If invisible text ends on a
12902 newline, reseat the iterator instead of bidi-iterating there one
12903 character at a time. (Bug#9610)
12904 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
12905 TO_CHARPOS if the bidi iterator is at base embedding level.
12907 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
12909 * lread.c (readevalloop): Use correct code for NBSP.
12910 (read1): Likewise. (Bug#9608)
12912 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
12914 * dbusbind.c (Fdbus_register_signal): When service is not
12915 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
12917 2011-09-25 Glenn Morris <rgm@gnu.org>
12919 * buffer.c (truncate-lines): Doc fix.
12921 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
12923 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
12924 (Fset_window_next_buffers): Doc fix.
12926 2011-09-24 Glenn Morris <rgm@gnu.org>
12928 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
12930 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
12932 Fix minor problems found by static checking.
12933 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
12934 * indent.c (Fvertical_motion): Fix == vs = typo.
12936 2011-09-24 Eli Zaretskii <eliz@gnu.org>
12938 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
12939 Default value is now t. Doc fix.
12941 * indent.c (Fvertical_motion): Compute and apply the overshoot
12942 logic when moving up, not only when moving down. Fix the
12943 confusing name and values of the it_overshoot_expected variable;
12944 logic changes accordingly. (Bug#9254) (Bug#9549)
12946 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
12947 CHARPOS is covered by a display string which includes newlines.
12948 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
12949 is covered by a display string with embedded newlines.
12951 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
12953 * dbusbind.c (Fdbus_register_signal): Add match rule to
12954 Vdbus_registered_objects_table. (Bug#9581)
12955 (Fdbus_register_method, Vdbus_registered_objects_table):
12958 2011-09-24 Jim Meyering <meyering@redhat.com>
12960 do not ignore write error for any output size
12961 The previous change was incomplete.
12962 While it makes emacs --batch detect the vast majority of stdout
12963 write failures, errors were still ignored whenever the output size is
12964 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
12965 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
12966 && echo FAIL: ignored write error
12967 FAIL: ignored write error
12968 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
12969 && echo FAIL: ignored write error
12970 FAIL: ignored write error
12971 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
12973 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
12975 * emacs.c (Fkill_emacs): In noninteractive mode exit
12976 non-successfully if a write error occurred on stdout. (Bug#9574)
12978 2011-09-21 Eli Zaretskii <eliz@gnu.org>
12980 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
12983 * dispextern.h (struct it): Update the comment documenting what
12986 2011-09-20 Eli Zaretskii <eliz@gnu.org>
12988 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
12989 a display string, extend search for cursor position to end of row.
12990 (find_row_edges): If the row ends in a newline from a display
12991 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
12992 Handle the case of a display string with multiple newlines.
12993 (Fcurrent_bidi_paragraph_direction): Fix search for previous
12994 non-empty line. Fixes confusing cursor motion with arrow keys at
12995 the beginning of a line that starts with whitespace.
12997 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
12999 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
13002 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
13004 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
13005 boolean (Bug#9154).
13007 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13009 * xdisp.c (display_line): Record maximum and minimum buffer
13010 positions even if no glyphs were produced (e.g., by a zero-width
13011 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
13012 buffer positions that will be removed from the glyph row because
13014 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
13015 column is beyond frame width: don't subtract 1 "pixel" when
13016 computing width of the stretch.
13017 (reseat_at_next_visible_line_start): Undo the change made on
13018 2011-09-17 that saved paragraph information and restored it after
13019 the call to `reseat'. (Bug#9545)
13021 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13023 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
13024 and turn window cursor on if cleared (Bug#9415).
13026 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
13028 * search.c (boyer_moore): Take unibyte characters from pattern
13029 literally. (Bug#9458)
13031 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13033 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
13035 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
13037 Fix minor problem found by static checking.
13038 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
13039 initialized, to pacify gcc -Wuninitialized.
13041 * fileio.c: Report proper errno when syscall falls.
13042 (Finsert_file_contents): Save and restore errno,
13043 so that report_file_error outputs the correct diagnostic.
13044 (Fwrite_region) [CLASH_DETECTION]: Likewise.
13046 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13048 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
13050 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13052 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
13053 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
13055 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13057 * xdisp.c (reseat_at_next_visible_line_start): Keep information
13058 about the current paragraph and restore it after the call to reseat.
13060 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
13061 (bidi_find_paragraph_start): Search back for paragraph beginning
13062 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
13063 (bidi_move_to_visually_next): Only trigger paragraph-related
13064 computations when the last character is a newline or at EOB, not
13065 just any NEUTRAL_B. (Bug#9470)
13067 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
13068 truncated lines if point is covered by a display string. (Bug#9524)
13070 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
13072 * xselect.c: Relax test for outgoing X longs (Bug#9498).
13073 (cons_to_x_long): New function.
13074 (lisp_data_to_selection_data): Use it. Correct the test for
13075 short-versus-long data; it was negated. Break out of vector
13076 loop, for efficiency, when a long datum is discovered.
13078 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
13080 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
13082 2011-09-16 Eli Zaretskii <eliz@gnu.org>
13084 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
13085 GCC PR/17406) by declaring this function with external scope.
13087 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13089 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
13090 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
13092 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
13094 * editfns.c (Fformat): Correctly handle text properties on "%%".

13100 * term.c (encode_terminal_code):
13101 * composite.c (composition_update_it, get_composition_id):
13102 * xdisp.c (get_next_display_element)
13103 (fill_composite_glyph_string): Add comments about special meaning
13104 of TAB characters in a composition.
13106 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13108 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
13109 This occurs when processing a multibyte format.
13110 Problem reported by Wolfgang Jenker.
13112 2011-09-15 Johan Bockgård <bojohan@gnu.org>
13114 * xdisp.c (try_cursor_movement): Only check for exact match if
13115 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
13117 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13119 Remove unused external symbols.
13120 * dispextern.h (calc_pixel_width_or_height): Remove decl.
13121 * xdisp.c (calc_pixel_width_or_height): Now static.
13122 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
13123 * indent.c (check_display_width):
13124 * w32term.c: Fix comment to match code.
13125 * xterm.c, xterm.h (x_catching_errors): Remove.
13127 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13129 * xselect.c: Use signed conversions more consistently (Bug#9498).
13130 (selection_data_to_lisp_data): Assume incoming selection data are
13131 signed integers, not unsigned. This is to be consistent with
13132 outgoing selection data, which was modified to use signed integers
13133 in as part of the fix to Bug#9196 in response to Jan D.'s comment
13134 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
13135 expects long, not unsigned long.
13137 2011-09-14 Eli Zaretskii <eliz@gnu.org>
13139 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
13140 computation of loop end. Reported by Johan Bockgård
13143 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
13145 * frame.c (Fother_visible_frames_p): Function deleted.
13147 2011-09-12 Eli Zaretskii <eliz@gnu.org>
13149 * indent.c (compute_motion): Process display vector front to back
13150 rather than the other way around. (Bug#2496)
13152 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
13154 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
13156 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
13158 * minibuf.c (Fread_from_minibuffer): Doc fix.
13160 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13162 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
13163 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
13165 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
13167 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
13168 value for non-existent files.
13170 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13172 * fileio.c (Finsert_file_contents): If the file cannot be opened,
13173 set its "size" to -1. This will set the modtime_size field of
13174 the corresponding buffer to -1, which is what
13175 verify-visited-file-modtime expects for files that do not exist.
13178 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
13180 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
13182 * lisp.h: ... from here. push_key_description is no longer
13183 defined in keyboard.c, so its declaration should not be in
13184 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
13185 logically belongs with push_key_description.
13187 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
13189 * buffer.h: Include <sys/types.h> instead of <time.h>.
13190 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
13191 Problem reported by Herbert J. Skuhra.
13193 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
13195 * xml.c (parse_region): Make the parsing work for
13196 non-comment-starting XML files again (bug#9144).
13198 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
13200 * image.c (gif_load): Fix calculation of bottom and right corner.
13203 2011-09-10 Eli Zaretskii <eliz@gnu.org>
13205 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
13206 redisplay in small windows.
13208 2011-09-09 Eli Zaretskii <eliz@gnu.org>
13210 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
13212 2011-09-08 Martin Rudalics <rudalics@gmx.at>
13214 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
13215 Operate on live windows only.
13217 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
13219 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
13221 2011-09-07 Eli Zaretskii <eliz@gnu.org>
13223 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
13224 only under bidi iteration.
13226 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
13228 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
13230 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13232 isnan: Fix porting problem to Solaris 10 with bundled gcc.
13233 Without this fix, the command to link temacs failed due to an
13234 undefined symbol __builtin_isnan. This is because
13235 /usr/include/iso/math_c99.h #defines isnan(x) to
13236 __builtin_isnan(x), but the bundled gcc, which identifies itself
13237 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
13239 * floatfns.c (isnan): #undef, and then #define to a clone of
13241 (Fisnan): Always define, since it's always available now.
13242 (syms_of_floatfns): Always define isnan at the Lisp level.
13244 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13246 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
13248 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13250 * fileio.c: Fix bugs with large file offsets (Bug#9428).
13251 The previous code assumed that file offsets (off_t values) fit in
13252 EMACS_INT variables, which is not true on typical 32-bit hosts.
13253 The code messed up by falsely reporting buffer overflow in cases
13254 such as (insert-file-contents "big" nil 1 2) into an empty buffer
13255 when "big" contains more than 2**29 bytes, even though this
13256 inserts just one byte and does not overflow the buffer.
13257 (Finsert_file_contents): Store file offsets as off_t
13258 values, not as EMACS_INT values. Check for overflow when
13259 converting between EMACS_INT and off_t. When checking for
13260 buffer overflow or for overlap, take the offsets into account.
13261 Don't use EMACS_INT for small values where int suffices.
13262 When checking for overlap, fix a typo: ZV was used where
13263 ZV_BYTE was intended.
13264 (Fwrite_region): Don't assume off_t fits into 'long'.
13265 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
13267 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
13269 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
13271 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13273 sprintf-related integer and memory overflow issues (Bug#9412).
13275 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
13276 (esprintf, exprintf, evxprintf): New functions.
13277 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
13278 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
13279 (modify_event_symbol): Do not assume that the length of
13280 name_alist_or_stem is safe to alloca and fits in int.
13281 (Fexecute_extended_command): Likewise for function name and binding.
13282 (Frecursion_depth): Wrap around reliably on integer overflow.
13283 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
13284 since some callers pass EMACS_INT values.
13285 (Fsingle_key_description): Don't crash if symbol name contains more
13286 than MAX_ALLOCA bytes.
13287 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
13288 (get_minibuffer): Arg is now EMACS_INT, not int.
13289 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
13290 (esprintf, exprintf, evxprintf): New decls.
13291 * window.h (command_loop_level, minibuf_level): Reflect API changes.
13293 * dbusbind.c (signature_cat): New function.
13294 (xd_signature, Fdbus_register_signal):
13295 Do not overrun buffer; instead, report string overflow.
13297 * dispnew.c (add_window_display_history): Don't overrun buffer.
13298 Truncate instead; this is OK since it's just a log.
13300 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
13301 even if the time zone offset is outlandishly large.
13302 Don't mishandle offset == INT_MIN.
13304 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
13305 when creating daemon; the previous buffer-overflow check was incorrect.
13307 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
13308 which has the guts of the old verror function.
13310 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
13311 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
13313 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
13314 (font_unparse_xlfd): Don't blindly alloca long strings.
13315 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
13316 fits in int, when using sprintf. Use single snprintf to count
13317 length of string rather than counting it via multiple sprintfs;
13318 that's simpler and more reliable.
13319 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
13320 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
13321 sprintf, in case result does not fit in int.
13323 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
13324 (fontset_from_font): Print it.
13326 * frame.c (tty_frame_count): Now printmax_t, not int.
13327 (make_terminal_frame, set_term_frame_name): Print it.
13328 (x_report_frame_params): In X, window IDs are unsigned long,
13329 not signed long, so print them as unsigned.
13330 (validate_x_resource_name): Check for implausibly long names,
13331 and don't assume name length fits in 'int'.
13332 (x_get_resource_string): Don't blindly alloca invocation name;
13333 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
13336 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
13337 (xg_check_special_colors, xg_set_geometry):
13338 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
13340 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
13341 Use esprintf, not sprintf, in case result does not fit in int.
13343 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13344 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
13345 it as a large positive number.
13346 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
13347 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
13349 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
13350 in case result does not fit in int.
13352 * print.c (float_to_string): Detect width overflow more reliably.
13353 (print_object): Make sprintf buffer a bit bigger, to avoid potential
13354 buffer overrun. Don't assume list length fits in 'int'. Treat
13355 print length of 0 as 0, not as infinity; to be consistent with other
13356 uses of print length in this function. Don't overflow print length
13357 index. Don't assume hash table size fits in 'long', or that
13358 vectorlike size fits in 'unsigned long'.
13360 * process.c (make_process): Use printmax_t, not int, to format
13361 process-name gensyms.
13363 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
13365 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
13366 to avoid potential buffer overrun.
13368 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
13369 if X resource line is longer than 512 bytes.
13371 * xfns.c (x_window): Make sprintf buffer a bit bigger
13372 to avoid potential buffer overrun.
13374 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
13376 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
13378 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
13380 Integer overflow fixes for scrolling, etc.
13381 Without these, Emacs silently mishandles large integers sometimes.
13382 For example, "C-u 4294967297 M-x recenter" was treated as if
13383 it were "C-u 1 M-x recenter" on a typical 64-bit host.
13385 * xdisp.c (try_window_id): Check Emacs fixnum range before
13386 converting to 'int'.
13388 * window.c (window_scroll_line_based, Frecenter):
13389 Check that an Emacs fixnum is in range before assigning it to 'int'.
13390 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
13391 values converted from Emacs fixnums.
13392 (Frecenter): Don't wrap around a line count if it is out of 'int'
13393 range; instead, treat it as an extreme value.
13394 (Fset_window_configuration, compare_window_configurations):
13395 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
13397 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
13398 that can exceed INT_MAX. Check that EMACS_INT value is in range
13399 before assigning it to the (possibly-narrower) index.
13400 (match_limit): Don't assume that a fixnum can fit in 'int'.
13402 * print.c (print_object): Use ptrdiff_t, not int, for index that can
13405 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
13406 (Fvertical_motion): Don't wrap around LINES values that don't fit
13407 in 'int'. Instead, treat them as extreme values. This is good
13408 enough for windows, which can't have more than INT_MAX lines anyway.
13410 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
13412 * Require libxml/parser.h to avoid compilation warning.
13414 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
13416 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
13417 since this reportedly can destroy thread storage.
13419 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
13421 * syntax.c (find_defun_start): Update all cache variables if
13422 exiting early (Bug#9401).
13424 2011-08-30 Eli Zaretskii <eliz@gnu.org>
13426 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
13428 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
13429 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
13430 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
13432 * term.c (tty_append_glyph): New function.
13433 (produce_stretch_glyph): Static function and its prototype deleted.
13435 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
13438 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
13440 * image.c (parse_image_spec): Check for nonnegative, not for positive,
13441 when checking :margin (Bug#9390).
13442 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
13443 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
13444 so that the name doesn't mislead. All uses changed.
13446 2011-08-28 Johan Bockgård <bojohan@gnu.org>
13448 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
13451 2011-08-27 Eli Zaretskii <eliz@gnu.org>
13453 * xdisp.c (move_it_to): Don't bail out early when reaching
13454 position beyond to_charpos, if we are scanning backwards.
13455 (move_it_vertically_backward): When DY == 0, make sure we get to
13456 the first character in the line after the newline.
13458 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
13460 * ccl.c: Improve and simplify overflow checking (Bug#9196).
13461 (ccl_driver): Do not generate an out-of-range pointer.
13462 (Fccl_execute_on_string): Remove unnecessary check for
13463 integer overflow, noted by Stefan Monnier in
13464 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
13465 Remove a FIXME that didn't need fixing.
13466 Simplify the newly-introduced buffer reallocation code.
13468 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
13470 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
13472 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
13474 Integer and memory overflow issues (Bug#9196).
13476 * doc.c (get_doc_string): Rework so that
13477 get_doc_string_buffer_size is the actual buffer size, rather than
13478 being 1 less than the actual buffer size; this makes xpalloc more
13481 * image.c (x_allocate_bitmap_record, cache_image):
13482 * xselect.c (Fx_register_dnd_atom):
13483 Simplify previous changes by using xpalloc.
13485 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
13486 since either will do and ptrdiff_t is convenient with xpalloc.
13488 * charset.c (charset_table_size)
13489 (struct charset_sort_data.priority): Now ptrdiff_t.
13490 (charset_compare): Don't overflow if priorities differ greatly.
13491 (Fsort_charsets): Don't assume list length fits in int.
13492 Check for size-calculation overflow when allocating sort data.
13493 (syms_of_charset): Allocate an initial charset table that is
13494 just under 64 KiB, to avoid problems with glibc malloc and mmap.
13496 * cmds.c (internal_self_insert): Check for size-calculation overflow.
13498 * composite.h (struct composition.glyph_len): Now int, not unsigned.
13499 The actual value is always <= INT_MAX, and leaving it unsigned made
13500 overflow checking harder.
13502 * dispextern.h (struct glyph_matrix.rows_allocated)
13503 (struct face_cache.size): Now ptrdiff_t, for convenience in use
13504 with xpalloc. The values are still always <= INT_MAX.
13506 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
13508 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
13509 (SAFE_NALLOCA): New macro.
13511 * region-cache.c (struct boundary.pos, find_cache_boundary)
13512 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
13513 (set_cache_region, invalidate_region_cache)
13514 (revalidate_region_cache, know_region_cache, region_cache_forward)
13515 (region_cache_backward, pp_cache):
13516 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
13517 so that ptrdiff_t * can be passed to xpalloc.
13518 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
13519 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
13520 (pp_cache): Don't assume cache_len fits in int.
13521 * region-cache.h: Adjust extern decls to match.
13523 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
13524 EMACS_INT, since either will do, for xpalloc.
13526 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
13527 (xnmalloc, xnrealloc, xpalloc): New functions.
13529 * bidi.c (bidi_shelve_header_size): New constant.
13530 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
13531 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
13533 * bidi.c (bidi_cache_shrink):
13534 * buffer.c (overlays_at, overlays_in, record_overlay_string)
13536 Don't update size of array until after memory allocation succeeds,
13537 because xmalloc/xrealloc may not return.
13538 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
13539 now that we have proper integer overflow checking.
13540 (record_overlay_string, overlay_strings): Catch overflows when
13541 calculating size of overlay_str_buf.
13543 * callproc.c (Fcall_process): Check for size overflow when
13544 calculating size of args2.
13545 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
13546 Normally we prefer signed values, but sticking with ptrdiff_t would
13547 require adding more-complicated checks.
13549 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
13550 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
13551 Redo buffer-overflow calculations to avoid integer overflow.
13552 Add a FIXME comment where memory seems to be over-allocated.
13554 * character.c (Fstring): Check for size-calculation overflow.
13556 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
13557 unnecessary integer overflow. Check for size overflow.
13558 (encode_coding_object): Don't update size until xmalloc succeeds.
13560 * composite.c (get_composition_id): Check for overflow in glyph
13561 length calculations.
13563 Integer and memory overflow fixes for display code.
13564 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
13565 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
13566 (scrolling_window): Check for overflow in size calculations.

13578 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
13579 (get_doc_string): Check for size calculation overflow.
13580 Don't update size until allocation succeeds.
13581 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
13582 EMACS_INT, where ptrdiff_t will do.
13583 (Fsubstitute_command_keys): Check for string overflow.

13587 (message_length): Now ptrdiff_t, not int.
13588 (Fmessage_box): Don't update size until allocation succeeds.
13589 Don't assume message length fits in int.
13590 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
13592 * emacs.c (main): Do not reallocate argv, since there is a null at
13593 the end that can be overwritten, and this way there's no need to
13594 worry about size-calculation overflow.
13595 (sort_args): Check for size-calculation overflow.
13597 * eval.c (init_eval_once, grow_specpdl): Don't update size until
13599 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
13601 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
13602 (x_set_scroll_bar_width, x_figure_window_size):
13603 Check for integer overflow.
13604 (x_set_alpha): Do not assume XINT fits in int.
13606 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
13607 This is for the members text_lines, text_cols, total_lines, total_cols,
13608 where the system imposes an 'int' limit.
13610 * fringe.c (Fdefine_fringe_bitmap):
13611 Don't update size until alloc works.
13613 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
13614 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
13616 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
13617 Check for size-calculation overflow.
13618 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
13619 do, as we prefer signed integers.
13620 (id_to_widget.max_size, id_to_widget.used)
13621 (xg_store_widget_in_map, xg_remove_widget_from_map)
13622 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
13623 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
13624 Use and return ptrdiff_t, not int.
13625 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
13626 * gtkutil.h: Change prototypes to match the above.
13628 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
13629 are duplicate now that they've been promoted to lisp.h.
13630 (x_allocate_bitmap_record, x_alloc_image_color)
13631 (make_image_cache, cache_image, xpm_load):
13632 Don't update size until alloc is done.

13643 Use ptrdiff_t, not int, to count maps.
13644 (read_char_minibuf_menu_prompt): Check for overflow in size
13645 calculations. Don't update size until allocation succeeds.
13646 Redo calculations to avoid overflow.
13647 * keyboard.h: Change prototypes to match the above.
13649 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,

13675 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
13676 for command line length. Do not attempt to address one before the
13677 beginning of an array, as that's not portable.
13679 * term.c (max_frame_lines): Remove; unused.
13680 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
13682 (encode_terminal_code, calculate_costs): Check for size

13705 Use ptrdiff_t, not int, for sizes.
13706 (Finternal_make_lisp_face, cache_face):
13707 Check for size calculation overflow.
13708 (cache_face): Treat size calculation overflows as if they were

13712 (Fx_change_window_property): Use ptrdiff_t, not int, to count
13713 sizes, since they can exceed INT_MAX in size. Check for size

13717 (xg_select): Check for size calculation overflow.
13718 Don't update size until alloc done.
13720 * xrdb.c (get_environ_db): Don't assume path length fits in int,

13723 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
13724 (X_LONG_MIN): New macros.
13725 Use them to make the following changes clearer.
13726 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
13727 This change doesn't affect the value now, but it may help remind
13728 future maintainers not to raise the value too much later.
13729 (SELECTION_QUANTUM): Remove, replacing with ...
13730 (selection_quantum): ... new function, which avoids overflow.
13732 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
13733 assumption that selection length fits in 'int'.

13745 (x_get_window_property, receive_incremental_selection)
13746 (lisp_data_to_selection_data, x_property_data_to_lisp):

13750 Don't store size until memory allocation succeeds.
13751 (x_get_window_property): Plug memory leak on memory exhaustion.
13752 Don't double-block input; malloc is safe here. Don't assume 2**34
13753 - 4 fits in unsigned long. Add an xassert to check
13754 XGetWindowProperty overflow. Be more careful about overflow
13755 calculations, and distinguish size from memory overflow better.
13756 (receive_incremental_selection): When tracing, don't assume
13757 unsigned int is less than INT_MAX.
13758 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
13759 harmful) conversions of unsigned short to int.
13760 (lisp_data_to_selection_data): Don't assume that integers
13761 in the range -65535 through -1 fit in an X unsigned short.
13762 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
13763 result parameters unless successful. Rely on cons_to_unsigned
13764 to report problems with elements; the old code wasn't right anyway.
13765 (x_check_property_data): Check for int overflow; we cannot use
13766 a wider type due to X limits.
13767 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

13799 * lisp.h (hash_lookup, hash_put):
13800 * minibuf.c (Ftest_completion):
13801 Use ptrdiff_t for hash table indexes, not int (which is too
13802 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
13803 32-bit --with-wide-int hosts).
13805 * charset.c (Fdefine_charset_internal): Check for integer overflow.
13806 Add a FIXME comment about memory leaks.
13807 (syms_of_charset): Don't assume xmalloc returns.
13809 Don't assume that stated character widths fit in int.

13811 * character.h (CHAR_WIDTH):
13812 * indent.c (MULTIBYTE_BYTES_WIDTH):
13813 Use sanitize_char_width to avoid undefined and/or bad behavior
13814 with outlandish widths.
13815 * character.h (sanitize_tab_width): Rename from sanitize_width,
13816 now that we have two such functions. All uses changed.
13817 (sanitize_char_width): New inline function.
13819 Don't assume that tab-width fits in int.
13820 * character.h (sanitize_width): New inline function.
13821 (SANE_TAB_WIDTH): New macro.

13832 (read_hex, load_charset_map_from_file): Check for integer overflow.
13834 * xterm.c: Don't go over XClientMessageEvent limit.
13835 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
13836 (x_send_scroll_bar_event): Likewise. Check that the size does not
13837 exceed limits imposed by XClientMessageEvent, as well as the usual
13838 ptrdiff_t and size_t limits.
13840 * keyboard.c: Overflow, signedness and related fixes.
13841 (make_lispy_movement): Use same integer type in forward decl
13842 that is used in the definition.
13843 (read_key_sequence, keyremap_step):
13844 Change bufsize argument back to int, undoing my 2011-03-30 change.
13845 We prefer signed types, and int is wide enough here.
13846 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
13847 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
13848 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
13849 length, not size_t. Use ptrdiff_t for index, not int.
13850 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
13851 possibility of integer overflow.
13853 Overflow, signedness and related fixes for images.
13855 * dispextern.h (struct it.stack[0].u.image.image_id)
13856 (struct_it.image_id, struct image.id, struct image_cache.size)
13857 (struct image_cache.used, struct image_cache.ref_count):
13858 * gtkutil.c (update_frame_tool_bar):

13863 * xdisp.c (calc_pixel_width_or_height):
13864 * xfns.c (image_cache_refcount):
13865 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
13866 on typical 64-bit hosts.
13868 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
13869 (x_bitmap_pixmap, x_create_x_image_and_pixmap):

13872 when the callers expect that.
13873 (image_ascent): Redo ascent calculation to avoid int overflow.
13874 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
13875 (lookup_image): Remove unnecessary tests.
13876 (xbm_image_p): Locals are now of int, not EMACS_INT,
13877 since parse_image_check makes sure they fit into int.
13878 (png_load, gif_load, svg_load_image):
13879 Prefer int to unsigned where either will do.
13880 (tiff_handler): New function, combining the cores of the
13881 old tiff_error_handler and tiff_warning_handler.
13882 This function is rewritten to use vsnprintf and thereby avoid
13883 stack buffer overflows. It uses only the features of vsnprintf
13884 that are common to both POSIX and native Microsoft.
13885 (tiff_error_handler, tiff_warning_handler): Use it.
13886 (tiff_load, gif_load, imagemagick_load_image):
13887 Don't assume :index value fits in 'int'.
13888 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
13889 (imagemagick_load_image): Check that crop parameters fit into
13890 the integer types that MagickCropImage accepts. Don't assume
13891 Vimagemagick_render_type has a nonnegative value. Don't assume
13892 size_t fits in 'long'.
13893 (gs_load): Use printmax_t to print the widest integers possible.
13894 Check for integer overflow when computing image height and width.
13896 2011-08-26 Eli Zaretskii <eliz@gnu.org>
13898 * xdisp.c (redisplay_window): Don't force window start if point

13906 handle_single_display_spec, not just 1 or zero.
13907 (handle_single_display_spec): If the display spec is of the form
13908 `(space ...)', and specifies display in the text area, return 2
13910 (try_cursor_movement): Check for the need to scroll more
13911 accurately, and prefer exact match for point under bidi.
13912 Don't advance `row' beyond the last row of the window.
13914 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
13915 into disp_prop; all users changed.
13917 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
13918 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
13919 for the text covered by the display property.

13929 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
13930 buffers, return left-to-right.
13931 (set_cursor_from_row): Consider candidate row a win if its glyph
13932 represents a newline and point is on that newline. Fixes cursor
13933 positioning on the newline at EOL of R2L text within L2R
13934 paragraph, and vice versa.
13935 (try_cursor_movement): Check continued rows, in addition to
13936 continuation rows. Fixes unwarranted scroll when point enters a
13937 continued line of R2L text within an L2R paragraph, or vice versa.
13938 (cursor_row_p): Consider the case of point being equal to
13939 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
13940 from the end of a short line to the beginning of a continued line
13941 of R2L text within L2R paragraph.
13942 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
13943 composed characters.
13945 * bidi.c (bidi_check_type): Use xassert.
13946 (bidi_cache_iterator_state): Update the disp_pos and disp_prop_p
13949 2011-08-23 Eli Zaretskii <eliz@gnu.org>

13956 * nsfont.m (ns_otf_to_script): Fix typo.
13958 2011-08-22 Kenichi Handa <handa@m17n.org>
13960 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
13961 extra slot even if the purpose is char-code-property-table.
13963 2011-08-23 Eli Zaretskii <eliz@gnu.org>
13965 * xdisp.c (redisplay_window): When computing centering_position,
13966 account for the height of the header line. (Bug#8874)
13968 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
13969 instead of CHAR_TO_BYTE. Fixes a crash when a completion
13970 candidate is selected by the mouse, and that candidate has a
13971 composed character under the mouse.
13973 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
13974 coordinates reported by pos-visible-in-window-p for a composed
13975 character in column zero.
13977 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
13979 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
13981 2011-08-22 Eli Zaretskii <eliz@gnu.org>
13983 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
13984 consider it a hit if to_charpos is anywhere in the range of the
13985 composed buffer positions.
13987 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
13989 * image.c (gif_load): Don't assume that each subimage has the same
13990 dimensions as the base image. Handle disposal method that is
13991 "undefined" by the gif spec (Bug#9335).
13993 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
13995 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

13998 2011-08-19 Eli Zaretskii <eliz@gnu.org>
14000 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
14001 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
14002 from an Org mode buffer to a Speedbar frame.
14004 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
14005 a composition, take its buffer position from IT->cmp_it.charpos.
14006 Fixes cursor positioning at the beginning of a line that begins
14007 with a composed character.
14009 2011-08-18 Eli Zaretskii <eliz@gnu.org>
14011 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
14012 character bidirectional type, use STRONG_L instead. Fixes crashes
14013 in a buffer produced by `describe-categories'.
14015 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
14016 members before the level stack, so they would be saved and
14017 restored when copying iterator state. Fixes incorrect reordering
14018 around TABs covered by display properties.
14020 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
14022 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

14092 * xdisp.c (move_it_in_display_line_to): Don't invoke
14093 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
14094 ppos_it. Fixes vertical cursor motion when line beginning is
14095 covered by an image. (Bug#9296)
14097 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
14099 * nsterm.h (ns_run_ascript): Declare.

14103 (ns_run_ascript): New function.
14104 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
14105 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
14106 the event loop. Get status from as_status (Bug#7276).
14108 * nsterm.m (sendEvent): If event is NSApplicationDefined and
14109 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
14110 the event loop (Bug#7276).
14112 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>

14136 (Fnetwork_interface_list): Allocate in increments of bytes instead
14137 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
14138 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
14140 (struct ifflag_def): notrailers is smart on OSX.
14141 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
14142 Get hardware address with getifaddrs if available.
14144 2011-08-12 Eli Zaretskii <eliz@gnu.org>
14146 * xdisp.c (iterate_out_of_display_property): xassert that
14147 IT->position is set to within IT->object's boundaries. Break from
14148 the loop as soon as EOB is reached; avoids infloops in redisplay

14150 Set IT->current to match the bidi iterator unconditionally.
14151 (push_display_prop): Allow GET_FROM_STRING as IT->method on
14152 entry. Force push_it to save on the stack the current
14153 buffer/string position, to be restored by pop_it. Fix flags in
14154 the iterator structure wrt the object coming from a display
14155 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
14156 properties. (Bug#9284)
14158 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
14160 * fontset.c (fontset_get_font_group): Add proper type checks.

14188 restore_point_unwind (Bug#5984).
14190 2011-08-07 Juri Linkov <juri@jurta.org>
14192 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
14193 to show the arg `TIME' instead of `TIMEVAL'.
14195 2011-08-06 Eli Zaretskii <eliz@gnu.org>
14197 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
14198 display property strides EOL and includes a newline, as in
14199 longlines-mode. (Bug#9254)
14200 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
14201 word-wrap under bidirectional display. (Bug#9224)
14203 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
14204 is non-zero, even if the data buffer is NULL. Fixes a crash in
14205 vertical-motion with longlines-mode. (Bug#9254)
14207 2011-08-05 Eli Zaretskii <eliz@gnu.org>
14209 * bidi.c <bidi_cache_total_alloc>: Now static.

14212 * xdisp.c (display_line): Release buffer allocated for shelved bidi
14215 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
14216 amount allocated this far in `bidi_cache_total_alloc'.
14217 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
14218 non-zero, only free the data buffer without restoring the cache
14219 contents. All callers changed.
14221 * dispextern.h (bidi_unshelve_cache): Update prototype.
14223 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
14224 (move_it_in_display_line, move_it_to)
14225 (move_it_vertically_backward, move_it_by_lines): Replace the call
14226 to xfree to an equivalent call to bidi_unshelve_cache.
14227 (move_it_in_display_line_to): Fix logic of returning
14228 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
14230 2011-08-05 Eli Zaretskii <eliz@gnu.org>
14232 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that

14284 DISP_PROP_P, and pass it to compute_display_string_pos.
14285 Only handle text covered by a display string if DISP_PROP_P is returned
14286 non-zero. All callers of bidi_fetch_char changed.

14290 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
14292 2010-12-03 Don March <don@ohspite.net>
14294 * keymap.c (Fdefine_key): Fix non-prefix key error message when
14295 last character M-[char] is translated to ESC [char] (bug#7541).
14297 2011-08-02 Kenichi Handa <handa@m17n.org>
14299 * lisp.h (uniprop_table): Extern it.
14301 * chartab.c (uniprop_table): Make it non-static.
14303 2011-08-01 Eli Zaretskii <eliz@gnu.org>
14305 * xdisp.c (forward_to_next_line_start): Accept additional argument
14306 BIDI_IT_PREV, and store into it the state of the bidi iterator had
14308 (reseat_at_next_visible_line_start): Use the bidi iterator state
14309 returned by forward_to_next_line_start to restore the state of
14310 it->bidi_it after backing up to previous newline. (Bug#9212)
14312 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
14314 * regex.c (re_comp): Protoize.
14315 (re_exec): Fix return type.
14316 (regexec): Fix type of `ret'. (Bug#9203)
14318 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14320 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
14321 This is needed if max-image-size is a floating-point number.
14323 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
14325 * print.c (print_object): Print empty symbol as ##.
14327 * lread.c (read1): Read ## as empty symbol.
14329 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
14331 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
14332 setting frame foreground color (Bug#9175).
14333 (x_set_background_color): Likewise.
14335 * nsmenu.m (-setText): Size tooltip dimensions precisely to
14336 contents (Bug#9176).
14337 (EmacsTooltip -init): Remove bezels and add shadows to
14340 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
14341 or scroll bar (Bug#8470).
14343 * nsfont.m (nsfont_open): Remove assignment to voffset and
14344 unnecessary vars hshink, expand, hd, full_height, min_height.
14345 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
14347 * nsterm.h (nsfont_info): Remove voffset field.
14349 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
14351 Implement strike-through and overline on NextStep (Bug#8863).
14353 * nsfont.m (nsfont_open): Use underline position provided by font,
14354 instead of hard-coded value of 2.
14355 (nsfont_draw): Call ns_draw_text_decoration instead.
14357 * nsterm.h: Add declaration for ns_draw_text_decoration.
14359 * nsterm.m (ns_draw_text_decoration): New function for drawing
14360 underline, overline, and strike-through.
14361 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
14362 ns_draw_text_decoration. Change treatment of cursor drawing to
14363 accommodate underlining, etc.
14365 2011-07-28 Eli Zaretskii <eliz@gnu.org>
14367 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
14370 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14372 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
14373 Without this fix, if a signal arrives just after memory fills up,
14374 'malloc' might be invoked reentrantly.
14376 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
14377 In other words, assume that every image size is allowed, on non-X
14378 hosts. This assumption is probably wrong, but it lets Emacs compile.
14380 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
14382 * regex.c (re_iswctype): Convert return values to boolean.
14384 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
14386 * xdisp.c (compute_display_string_pos): Don't use cached display
14387 string position if the buffer had its restriction changed.
14390 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14392 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
14394 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
14396 Integer signedness and overflow and related fixes. (Bug#9079)
14398 * bidi.c: Integer size and overflow fixes.
14399 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
14400 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
14401 (bidi_cache_find_level_change, bidi_cache_ensure_space)
14402 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
14403 (bidi_find_other_level_edge):
14404 Use ptrdiff_t instead of EMACS_INT where either will do.
14405 This works better on 32-bit hosts configured --with-wide-int.
14406 (bidi_cache_ensure_space): Check for size-calculation overflow.
14407 Use % rather than repeated addition, for better worst-case speed.
14408 Don't set bidi_cache_size until after xrealloc returns, because it
14410 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
14411 (bidi_cache_ensure_space): Also check that the bidi cache size
14412 does not exceed that of the largest Lisp string or buffer. See Eli
14413 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
14415 * alloc.c (__malloc_size_t): Remove.
14416 All uses replaced by size_t. See Andreas Schwab's note
14417 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
14419 * image.c: Improve checking for integer overflow.
14420 (check_image_size): Assume that f is nonnull, since
14421 it is always nonnull in practice. This is one less thing to
14422 worry about when checking for integer overflow later.
14423 (x_check_image_size): New function, which checks for integer
14424 overflow issues inside X.
14425 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
14426 This removes the need for a memory_full check.
14427 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
14428 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
14429 (xbm_read_bitmap_data): Change locals back to 'int', since
14430 their values must fit in 'int'.
14431 (xpm_load_image, png_load, tiff_load):
14432 Invoke x_create_x_image_and_pixmap earlier,
14433 to avoid much needless work if the image is too large.
14434 (tiff_load): Treat overly large images as if
14435 x_create_x_image_and_pixmap failed, not as malloc failures.
14436 (gs_load): Use x_check_image_size.
14438 * gtkutil.c: Omit integer casts.
14439 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
14440 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
14442 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
14444 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
14445 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
14446 would wrongly return t on a 64-bit host.
14448 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
14449 The plain *_OVERFLOW macros run afoul of GCC bug 49705
14450 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
14451 and therefore cause GCC to emit a bogus diagnostic in some cases.
14453 * image.c: Integer signedness and overflow and related fixes.
14454 This is not an exhaustive set of fixes, but it's time to
14455 record what I've got.
14456 (lookup_pixel_color, check_image_size): Remove redundant decls.
14457 (check_image_size): Don't assume that arbitrary EMACS_INT values
14458 fit in 'int', or that arbitrary 'double' values fit in 'int'.
14459 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
14460 (tiff_load, imagemagick_load_image):
14461 Check for overflow in size calculations.
14462 (x_create_x_image_and_pixmap): Remove unnecessary test for
14463 xmalloc returning NULL; that can't happen.
14464 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
14465 (xpm_color_bucket): Use better integer hashing function.
14466 (xpm_cache_color): Don't possibly over-allocate memory.
14467 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
14468 (gif_memory_source):
14469 Use ptrdiff_t, not int or size_t, to record sizes.
14470 (png_load): Don't assume values greater than 2**31 fit in 'int'.
14471 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
14472 either works, as we prefer signed integers.
14473 (tiff_read_from_memory, tiff_write_from_memory):
14474 Return tsize_t, not size_t, since that's what the TIFF API wants.
14475 (tiff_read_from_memory): Don't fail simply because the read would
14476 go past EOF; instead, return a short read.
14477 (tiff_load): Omit no-longer-needed casts.
14478 (Fimagemagick_types): Don't assume size fits into 'int'.
14480 Improve hashing quality when configured --with-wide-int.
14481 * fns.c (hash_string): New function, taken from sxhash_string.
14482 Do not discard information about ASCII character case; this
14483 discarding is no longer needed.
14484 (sxhash-string): Use it. Change sig to match it. Caller changed.
14485 * lisp.h: Declare it.
14486 * lread.c (hash_string): Remove, since we now use fns.c's version.
14487 The fns.c version returns a wider integer if --with-wide-int is
14488 specified, so this should help the quality of the hashing a bit.
14490 * emacs.c: Integer overflow minor fix.
14491 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
14492 Define only if GNU_LINUX.
14493 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
14495 * dispnew.c: Integer signedness and overflow fixes.
14496 Remove unnecessary forward decls, that were a maintenance hassle.
14497 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
14499 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
14500 (scrolling_window): Use ptrdiff_t, not int, for byte count.
14501 (prepare_desired_row, line_draw_cost):
14502 Use int, not unsigned, where either works.
14503 (save_current_matrix, restore_current_matrix):
14504 Use ptrdiff_t, not size_t, where either works.
14505 (init_display): Check for overflow more accurately, and without
14506 relying on undefined behavior.
14508 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
14509 Remove, replacing with the new symbols in lisp.h. All uses changed.
14510 * fileio.c (make_temp_name):
14511 * filelock.c (lock_file_1, lock_file):
14512 * xdisp.c (message_dolog):
14513 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
14514 Use pMd etc. instead.
14515 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
14516 replacing the pWIDE etc. symbols removed from editfns.c.
14518 * keyboard.h (num_input_events): Now uintmax_t.
14519 This is (very slightly) less likely to mess up due to wraparound.
14522 * buffer.c: Integer signedness fixes.
14523 (alloc_buffer_text, enlarge_buffer_text):
14524 Use ptrdiff_t rather than size_t when either will do, as we prefer
14527 * alloc.c: Integer signedness and overflow fixes.
14528 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
14529 (__malloc_size_t): Default to size_t, not to int.
14530 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
14531 (Fgarbage_collect, mark_object_loop_halt, mark_object):
14532 Prefer ptrdiff_t to size_t when either would do, as we prefer
14534 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
14535 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
14536 Now const. Initialize with values that are in range even if char
14538 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
14539 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
14540 These functions do the right thing with sizes > 2**32.
14541 (check_depth): Now ptrdiff_t, not int.
14542 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
14543 Adjust to new way of storing sizes. Check for size overflow bugs
14545 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
14546 slightly wrong anyway, as it missed one instance of
14547 XMALLOC_OVERRUN_CHECK_OVERHEAD.
14548 (refill_memory_reserve): Omit needless cast to size_t.
14549 (mark_object_loop_halt): Mark as externally visible.
14551 * xselect.c: Integer signedness and overflow fixes.
14552 (Fx_register_dnd_atom, x_handle_dnd_message):
14553 Use ptrdiff_t, not size_t, since we prefer signed.
14554 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
14555 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
14556 x_dnd_atoms_size and x_dnd_atoms_length.
14558 * doprnt.c: Prefer signed to unsigned when either works.
14560 * doprnt.c (doprnt):
14562 * xdisp.c (vmessage):
14563 Use ptrdiff_t, not size_t, when using or implementing doprnt,
14564 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
14565 prefer signed arithmetic to avoid comparison confusion.
14566 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
14567 but is a bit tricky.
14569 Assume freestanding C89 headers, string.h, stdlib.h.
14570 * data.c, doprnt.c, floatfns.c, print.c:
14571 Include float.h unconditionally.
14572 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
14573 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
14574 * regex.c: Likewise for stddef.h, string.h.
14575 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
14576 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
14577 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
14578 (STDC_HEADERS): Remove obsolete defines.
14579 * sysdep.c: Include limits.h unconditionally.
14581 Assume support for memcmp, memcpy, memmove, memset.
14582 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
14583 * regex.c (memcmp, memcpy):
14584 Remove; we assume C89 now.
14586 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
14587 (__malloc_safe_bcopy): Remove; no longer needed.
14589 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
14590 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
14591 well either way, and we prefer signed to unsigned.
14593 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
14595 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
14596 closes the connection while we're reading (bug#9182).
14598 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
14600 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
14601 are specified (Bug#9168).
14603 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
14605 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
14606 Found by GCC static checking and --with-wide-int on a 32-bit host.
14608 2011-07-25 Eli Zaretskii <eliz@gnu.org>
14610 * xdisp.c (compute_display_string_pos): Fix logic of caching
14611 previous display string position. Initialize cached_prev_pos to
14612 -1. Fixes slow-down at the beginning of a buffer.
14614 2011-07-24 Eli Zaretskii <eliz@gnu.org>
14616 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
14617 for attrs[LFACE_FONTSET_INDEX].
14619 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
14621 * xml.c (parse_region): Remove unused local
14622 that was recently introduced.
14624 2011-07-23 Eli Zaretskii <eliz@gnu.org>
14626 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
14627 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
14629 * xdisp.c (move_it_in_display_line_to): Record the best matching
14630 position for TO_CHARPOS while scanning the line, and restore it on
14631 exit if none of the characters scanned was an exact match.
14632 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
14633 when exact match is impossible due to invisible text, and the
14634 lines are truncated.
14636 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
14638 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
14641 2011-07-22 Eli Zaretskii <eliz@gnu.org>
14643 Fix a significant slow-down of cursor motion with C-n, C-p,
14644 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
14645 auto-repeat under bidi redisplay in fontified buffers.
14646 * xdisp.c (compute_stop_pos_backwards): New function.
14647 (next_element_from_buffer): Call compute_stop_pos_backwards to
14648 find a suitable prev_stop when we find ourselves before
14650 (reseat): Don't look for prev_stop, as that could mean a very long
14652 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
14653 <cached_disp_overlay_modiff>: Cache for last found display string
14655 (compute_display_string_pos): Return the cached position if asked
14656 about the same buffer in the same area of character positions, and
14657 the buffer wasn't changed since the time the display string
14658 position was cached.
14660 2011-07-22 Eli Zaretskii <eliz@gnu.org>
14662 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
14663 is an integer, which is important for empty lines. (Bug#9149)
14665 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
14667 * frame.c (Fmodify_frame_parameters): In tty case, update the
14668 default face if necessary (Bug#4238).
14670 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
14672 * editfns.c (Fstring_to_char): No need to explain what a character
14673 is in the docstring (Bug#6576).
14675 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
14677 * xml.c (parse_region): Make sure we always return a tree.
14679 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
14681 * xml.c (parse_region): If a document contains only comments,
14684 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
14686 * xml.c (make_dom): Return comments, too.
14688 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
14691 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
14692 and the surrounding thread.
14693 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
14694 rather than fgets, and retry after EINTR. Otherwise, 'emacs
14695 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
14697 * s/openbsd.h (BROKEN_SIGIO): Define.
14698 * unexelf.c (unexec) [__OpenBSD__]:
14699 Don't update the .mdebug section of the Alpha COFF symbol table.
14701 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14703 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
14706 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
14708 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
14709 This fixes some race conditions on the permissions of any newly
14712 * alloc.c (valid_pointer_p): Use pipe, not open.
14713 This fixes some permissions issues when debugging.
14715 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
14716 If fchown fails to set both uid and gid, try to set just gid,
14717 as that is sometimes allowed. Adjust the file's mode to eliminate
14718 setuid or setgid bits that are inappropriate if fchown fails.
14720 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
14722 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
14723 to compare Lisp_Objects.
14724 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
14725 global_gnutls_log_level, don't mistake it for a Lisp_Object.
14726 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
14728 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
14730 * lread.c (read_integer): Unread even EOF character.
14731 (read1): Likewise. Properly record start position of symbol.
14733 * lread.c (read1): Read `#:' as empty uninterned symbol if no
14734 symbol character follows.

14738 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
14739 This works around a problem with the previous change to Fcopy_file.
14740 Recent glibc declares fchown with __attribute__((warn_unused_result)),
14741 and without this change, GCC might complain about discarding
14742 fchown's return value.
14744 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
14746 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).

14758 keyboard.c and process.c (bug#1858).
14760 2011-07-09 Lawrence Mitchell <wence@gmx.li>
14762 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.

14769 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
14771 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
14772 quotes the next character, and doesn't affect other longer
14773 sequences (bug#8935).

14776 `eval-buffer' and `eval-defun' that's affected by
14777 `lexical-binding' (bug#8460).

14787 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
14788 (elsz): Now a signed constant, not a size_t var. We prefer signed
14789 types to unsigned, to avoid integer comparison confusion. Without
14790 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
14791 "cannot optimize loop, the loop counter may overflow", a symptom
14793 * indent.c (Fvertical_motion): Mark locals as initialized.
14794 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
14796 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>

14840 the iterator is before prev_stop.
14841 (init_iterator): Initialize bidi_p from the default value of

14888 (reseat_1): Remove redundant setting of string_from_display_prop_p.
14889 (push_display_prop): xassert that we are iterating a buffer.

14893 (push_display_prop): Set up the `unibyte' member of bidi_it.string
14894 correctly. Don't assume unibyte strings are not bidi-reordered.

15359 Random fixes. E.g., (random) never returned negative values.
15360 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
15361 subseconds part to the entropy, as that's a bit more random.
15362 Prefer signed to unsigned, since the signedness doesn't matter and
15363 in general we prefer signed. When given a limit, use a
15364 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
15365 latter isn't right if USE_2_TAGS_FOR_INTS.
15366 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
15367 not 0..VALMASK. Don't discard "excess" bits that random () returns.

15391 error be more correct.
15393 * fns.c (Frequire): Remove the mention of the .gz files, since

15410 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
15411 Also (re)move comments that are misplaced or no longer relevant.

15513 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
15514 signed bit field, as this assumption is not portable and it makes
15515 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
15516 "char debug_on_exit : 1" as this is not portable either; instead,
15517 use the portable "unsigned int debug_on_exit : 1". Remove unused
15518 member evalargs. Remove obsolete comments about cc bombing out.

15614 Use gnulib's dup2 module instead of rolling our own.
15615 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.

15682 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
15684 Integer and buffer overflow fixes (Bug#8873).
15686 * print.c (printchar, strout): Check for string overflow.
15687 (PRINTPREPARE, printchar, strout):
15688 Don't set size unless allocation succeeds.
15690 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
15691 for sizes. Check for string overflow more accurately.
15692 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
15694 * macros.c: Integer and buffer overflow fixes.
15695 * keyboard.h (struct keyboard.kbd_macro_bufsize):
15696 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
15697 Use ptrdiff_t, not int, for sizes.
15698 Don't increment bufsize until after realloc succeeds.
15699 Check for size-calculation overflow.
15700 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
15702 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
15704 * lread.c: Integer overflow fixes.
15705 (read_integer): Radix is now EMACS_INT, not int,
15706 to improve quality of diagnostics for out-of-range radices.
15707 Calculate buffer size correctly for out-of-range radices.
15708 (read1): Check for integer overflow in radices, and in
15709 read-circle numbers.
15710 (read_escape): Avoid int overflow.
15711 (Fload, openp, read_buffer_size, read1)
15712 (substitute_object_recurse, read_vector, read_list, map_obarray):
15713 Use ptrdiff_t, not int, for sizes.

15728 2011-06-22 Leo Liu <sdl.web@gmail.com>
15730 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
15731 Move to minibuffer.el.
15733 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
15735 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
15736 The following patches are for when GLYPH_DEBUG && !XASSERT.
15737 * dispextern.h (trace_redisplay_p, dump_glyph_string):
15738 * dispnew.c (flush_stdout):
15739 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
15740 Mark as externally visible.
15741 * dispnew.c (check_window_matrix_pointers): Now static.
15742 * dispnew.c (window_to_frame_vpos):
15743 * xfns.c (unwind_create_frame):
15744 * xterm.c (x_check_font): Remove unused local.
15745 * scroll.c (CHECK_BOUNDS):
15746 * xfaces.c (cache_fache): Rename local to avoid shadowing.
15747 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
15748 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
15749 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
15750 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
15752 (debug_method_add): Use va_list and vsprintf rather than relying
15753 on undefined behavior with wrong number of arguments.
15754 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
15755 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
15756 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
15757 since we're not interested in debugging glyphs with old libraries.
15758 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
15759 GCC 4.6.0's static checking.
15761 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
15763 Integer overflow and signedness fixes (Bug#8873).

15772 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
15773 (x_create_bitmap_from_xpm_data):
15774 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
15775 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
15777 * xfaces.c (load_pixmap):
15778 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
15779 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
15780 (.bitmaps_last, struct x_output.icon_bitmap):
15781 Use ptrdiff_t, not int, for bitmap indexes.
15782 (x_allocate_bitmap_record): Check for size overflow.
15783 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
15785 Use ptrdiff_t, not int, for overlay counts.
15786 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
15787 * editfns.c (overlays_around, get_pos_property):
15788 * textprop.c (get_char_property_and_overlay):
15789 * xdisp.c (next_overlay_change, note_mouse_highlight):
15790 * xfaces.c (face_at_buffer_position):
15791 * buffer.c (OVERLAY_COUNT_MAX): New macro.
15792 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
15793 (Fnext_overlay_change, Fprevious_overlay_change)
15794 (mouse_face_overlay_overlaps, Foverlays_in):
15795 Use ptrdiff_t, not int, for sizes.
15796 (overlays_at, overlays_in): Check for size-calculation overflow.
15798 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
15800 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
15801 (x_session_initialize): Do not assume string length fits in int.
15803 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
15804 This is unlikely, but can occur if DPI is outlandish.
15806 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
15807 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
15809 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
15810 * xrdb.c (magic_file_p, search_magic_path):
15811 Omit last arg SUFFIX; it was always 0. All callers changed.
15812 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
15814 * xfont.c (xfont_match): Avoid need for strlen.
15816 * xfns.c: Don't assume strlen fits in int.
15817 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
15819 * xdisp.c (message_log_check_duplicate): Return intmax_t,
15820 not unsigned long, as we prefer signed integers. All callers changed.
15821 Detect integer overflow in repeat count.
15822 (message_dolog): Don't assume print length fits in 39 bytes.
15823 (display_mode_element): Don't assume strlen fits in int.
15825 * termcap.c: Don't assume sizes fit in int and never overflow.
15826 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
15827 (gobble_line): Check for size-calculation overflow.
15829 * minibuf.c (Fread_buffer):
15830 * lread.c (intern, intern_c_string):
15831 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

15834 * keyboard.c (parse_tool_bar_item):
15835 * gtkutil.c (style_changed_cb): Avoid need for strlen.
15837 * font.c: Don't assume string length fits in int.
15838 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
15839 Use ptrdiff_t, not int.
15840 (font_intern_prop): Don't assume string length fits in int.
15841 Don't assume integer property fits in fixnum.
15842 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
15844 * filelock.c: Fix some buffer overrun and integer overflow issues.
15845 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
15846 Reformulate so as not to need the command string.
15847 Invoke gzip -cd rather than gunzip, as it's more portable.
15848 (lock_info_type, lock_file_1, lock_file):
15849 Don't assume pid_t and time_t fit in unsigned long.
15850 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
15851 (current_lock_owner): Prefer signed type for sizes.
15852 Use memcpy, not strncpy, where memcpy is what is really wanted.
15853 Don't assume (via atoi) that time_t and pid_t fit in int.
15854 Check for time_t and/or pid_t out of range, e.g., via a network share.
15855 Don't alloca where an auto var works fine.
15857 * fileio.c: Fix some integer overflow issues.
15858 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
15859 Don't assume string length fits in int.
15860 (directory_file_name): Don't assume string length fits in long.
15861 (make_temp_name): Don't assume pid fits in int, or that its print
15862 length is less than 20.
15864 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
15866 * coding.c (make_subsidiaries): Don't assume string length fits in int.
15868 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
15870 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
15871 We prefer signed integers, even for size calculations.
15873 * emacs.c: Don't assume string length fits in 'int'.
15874 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
15875 (main): Don't invoke strlen when not needed.
15877 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
15878 (XD_DEBUG_MESSAGE): Don't waste a byte.
15880 * callproc.c (getenv_internal_1, getenv_internal)
15881 (Fgetenv_internal):
15882 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
15884 * lread.c (invalid_syntax): Omit length argument.
15885 All uses changed. This doesn't fix a bug, but it simplifies the
15886 code away from its former Hollerith-constant appearance, and it's
15887 one less 'int' to worry about when looking at integer-overflow issues.
15888 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
15890 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
15891 This didn't break anything, but it didn't help either.
15892 It's confusing to put a bogus integer in a place where the actual
15893 value does not matter.
15894 (LIST_END_P): Remove unused macro and its bogus comment.
15895 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
15897 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
15898 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
15900 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
15901 We prefer signed types, and the value cannot exceed the EMACS_INT
15902 range anyway (because otherwise the length would not be representable).
15903 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
15904 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
15905 This avoids a GCC warning when WIDE_EMACS_INT.
15907 * indent.c (sane_tab_width): New function.
15908 (current_column, scan_for_column, Findent_to, position_indentation)
15909 (compute_motion): Use it. This is just for clarity.
15910 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
15912 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
15914 * lisp.h (lint_assume): New macro.
15915 * composite.c (composition_gstring_put_cache):
15916 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
15918 * editfns.c, insdel.c:
15919 Omit unnecessary forward decls, to simplify future changes.
15921 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
15923 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
15925 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
15926 Use much-faster test for byte-length change.
15927 Don't assume string byte-length fits in 'int'.
15928 Check that character arg fits in 'int'.
15929 (mapcar1): Declare byte as byte, for clarity.
15931 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
15933 * fns.c (concat): Catch string overflow earlier.
15934 Do not rely on integer wraparound.
15936 * dispextern.h (struct it.overlay_strings_charpos)
15937 (struct it.selective): Now EMACS_INT, not int.
15938 * xdisp.c (forward_to_next_line_start)
15939 (back_to_previous_visible_line_start)
15940 (reseat_at_next_visible_line_start, next_element_from_buffer):
15941 Don't arbitrarily truncate the value of 'selective' to int.
15943 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
15945 * composite.c: Don't truncate sizes to 'int'.
15946 (composition_gstring_p, composition_reseat_it)
15947 (composition_adjust_point): Use EMACS_INT, not int.
15948 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
15949 not EMACS_UINT, for indexes.
15951 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
15953 * buffer.c: Include <verify.h>.
15954 (struct sortvec.priority, struct sortstr.priority):
15955 Now EMACS_INT, not int.
15956 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
15957 (struct sortstr.size, record_overlay_string)
15958 (struct sortstrlist.size, struct sortlist.used):
15959 Don't truncate size to int.
15960 (record_overlay_string): Check for size-calculation overflow.
15961 (init_buffer_once): Check at compile-time, not run-time.
15963 2011-06-22 Jim Meyering <meyering@redhat.com>
15965 Don't leak an XBM-image-sized buffer
15966 * image.c (xbm_load): Free the image buffer after using it.
15968 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
15971 * composite.c (find_automatic_composition): Omit needless 'return 0;'
15972 that Sun C diagnosed.
15973 * fns.c (secure_hash): Fix pointer signedness issue.
15974 * intervals.c (static_offset_intervals): New function.
15975 (offset_intervals): Use it.
15977 2011-06-21 Leo Liu <sdl.web@gmail.com>
15980 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
15983 * fns.c (secure_hash): Rename from crypto_hash_function and change
15984 the first arg to accept symbols.
15985 (Fsecure_hash): New primitive.
15986 (syms_of_fns): New symbols.
15988 2011-06-20 Deniz Dogan <deniz@dogan.se>
15990 * process.c (Fset_process_buffer): Clarify return value in
15993 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
15995 * dispnew.c (add_window_display_history): Use BVAR.
15997 * xdisp.c (debug_method_add): Use BVAR.
15998 (check_window_end, dump_glyph_matrix, dump_glyph)
15999 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
16001 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
16004 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
16005 check till after the cache is created in init_frame_faces.
16007 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
16009 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
16011 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
16013 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
16014 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
16015 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
16017 Improve buffer-overflow checking (Bug#8873).
16018 * fileio.c (Finsert_file_contents):
16019 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
16020 Remove the old (too-loose) buffer overflow checks.
16021 They weren't needed, since make_gap checks for buffer overflow.
16022 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
16023 The old code merely checked for Emacs fixnum overflow, and relied
16024 on undefined (wraparound) behavior. The new code avoids undefined
16025 behavior, and also checks for ptrdiff_t and/or size_t overflow.
16027 * editfns.c (Finsert_char): Don't dump core with very negative counts.
16028 Tune. Don't use wider integers than needed. Don't use alloca.
16029 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
16031 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
16033 * insdel.c, lisp.h (buffer_overflow): New function.
16034 (insert_from_buffer_1, replace_range, replace_range_2):
16035 * insdel.c (make_gap_larger):
16036 * editfns.c (Finsert_char):
16037 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
16039 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
16041 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
16043 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
16045 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
16046 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
16048 * fileio.c: Don't assume EMACS_INT fits in off_t.
16049 (emacs_lseek): New static function.
16050 (Finsert_file_contents, Fwrite_region): Use it.
16051 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
16053 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
16055 * fns.c: Don't overflow int when computing a list length.
16056 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
16057 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
16058 truncation on 64-bit hosts. Check for QUIT every
16059 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
16060 faster and is responsive enough.
16061 (Flength): Report an error instead of overflowing an integer.
16062 (Fsafe_length): Return a float if the value is not representable
16063 as a fixnum. This shouldn't happen except in contrived situations.
16064 (Fnthcdr, Fsort): Don't assume list length fits in int.
16065 (Fcopy_sequence): Don't assume vector length fits in int.
16067 * alloc.c: Check that resized vectors' lengths fit in fixnums.
16068 (header_size, word_size): New constants.
16069 (allocate_vectorlike): Don't check size overflow here.
16070 (allocate_vector): Check it here instead, since this is the only
16071 caller of allocate_vectorlike that could cause overflow.
16072 Check that the new vector's length is representable as a fixnum.
16074 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
16075 The previous code was bogus. For example, next_almost_prime (32)
16076 returned 39, which is undesirable as it is a multiple of 3; and
16077 next_almost_prime (24) returned 25, which is a multiple of 5 so
16078 why was the code bothering to check for multiples of 7?
16080 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
16082 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
16084 Variadic C functions now count arguments with ptrdiff_t.
16085 This partly undoes my 2011-03-30 change, which replaced int with size_t.
16086 Back then I didn't know that the Emacs coding style prefers signed int.
16087 Also, in the meantime I found a few more instances where arguments
16088 were being counted with int, which may truncate counts on 64-bit
16089 machines, or EMACS_INT, which may be unnecessarily wide.
16090 * lisp.h (struct Lisp_Subr.function.aMANY)
16091 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
16092 Arg counts are now ptrdiff_t, not size_t.
16093 All variadic functions and their callers changed accordingly.
16094 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
16095 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
16096 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
16097 * callint.c (Fcall_interactively): Check arg count for overflow,
16098 to avoid potential buffer overrun. Use signed char, not 'int',
16099 for 'varies' array, so that we needn't bother to check its size
16100 calculation for overflow.
16101 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
16102 * eval.c (apply_lambda):
16103 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
16104 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
16105 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
16107 * callint.c (Fcall_interactively): Don't use index var as event count.
16109 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
16110 * mem-limits.h (SIZE): Remove; no longer used.
16112 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
16114 Remove unnecessary casts.
16115 * xterm.c (x_term_init):
16116 * xfns.c (x_set_border_pixel):
16117 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
16118 These aren't needed now that we assume ANSI C.
16120 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
16121 It's more likely to cause problems (due to unsigned overflow)
16124 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
16126 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
16128 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
16130 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
16132 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
16134 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
16136 GLYPH_CODE_FACE returns EMACS_INT, not int.
16137 * dispextern.h (merge_faces):
16138 * xfaces.c (merge_faces):
16139 * xdisp.c (get_next_display_element, next_element_from_display_vector):
16140 Don't assume EMACS_INT fits in int.
16142 * character.h (CHAR_VALID_P): Remove unused parameter.
16143 * fontset.c, lisp.h, xdisp.c: All uses changed.
16145 * editfns.c (Ftranslate_region_internal): Omit redundant test.
16147 * fns.c (concat): Minor tuning based on overflow analysis.
16148 This doesn't fix any bugs. Use int to hold character, instead
16149 of constantly refetching from Emacs object. Use XFASTINT, not
16150 XINT, for value known to be a character. Don't bother comparing
16151 a single byte to 0400, as it's always less.
16153 * floatfns.c (Fexpt):
16154 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
16156 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
16159 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
16161 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
16162 Without this fix, on a 64-bit host (aset S 0 4294967386) would
16163 incorrectly succeed when S was a string, because 4294967386 was
16164 truncated before it was used.
16166 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
16167 Otherwise, an out-of-range integer could cause undefined behavior
16170 * composite.c: Use int, not EMACS_INT, for characters.
16171 (fill_gstring_body, composition_compute_stop_pos): Use int, not
16172 EMACS_INT, for values that are known to be in character range.
16173 This doesn't fix any bugs but is the usual style inside Emacs and
16174 may generate better code on 32-bit machines.
16176 Make sure a 64-bit char is never passed to ENCODE_CHAR.
16177 This is for reasons similar to the recent CHAR_STRING fix.
16178 * charset.c (Fencode_char): Check that character arg is actually
16179 a character. Pass an int to ENCODE_CHAR.
16180 * charset.h (ENCODE_CHAR): Verify that the character argument is no
16181 wider than 'int', as a compile-time check to prevent future regressions
16184 * character.c (char_string): Remove unnecessary casts.
16186 Make sure a 64-bit char is never passed to CHAR_STRING.
16187 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
16188 by silently ignoring the top 32 bits, allowing some values
16189 that were far too large to be valid characters.
16190 * character.h: Include <verify.h>.
16191 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
16192 arguments are no wider than unsigned, as a compile-time check
16193 to prevent future regressions in this area.
16195 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
16196 (Fsubst_char_in_region):
16198 * xdisp.c (decode_mode_spec_coding):
16199 Adjust to CHAR_STRING's new requirement.
16200 * editfns.c (Finsert_char, Fsubst_char_in_region):
16201 * fns.c (concat): Check that character args are actually
16202 characters. Without this test, these functions did the wrong
16203 thing with wildly out-of-range values on 64-bit hosts.
16205 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
16206 These casts should not be needed on 32-bit hosts, either.
16207 * keyboard.c (read_char):
16208 * lread.c (Fload): Remove casts to unsigned.
16210 * lisp.h (UNSIGNED_CMP): New macro.
16211 This fixes comparison bugs on 64-bit hosts.
16212 (ASCII_CHAR_P): Use it.
16213 * casefiddle.c (casify_object):
16214 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
16215 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
16216 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
16217 * dispextern.h (FACE_FROM_ID):
16218 * keyboard.c (read_char): Use UNSIGNED_CMP.
16220 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
16221 not to EMACS_INT, to avoid GCC warning.
16223 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
16225 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
16226 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
16227 isn't needed on 32-bit machines.
16229 * buffer.c (Fgenerate_new_buffer_name):
16230 Use EMACS_INT for count, not int.
16231 (advance_to_char_boundary): Return EMACS_INT, not int.
16233 * data.c (Qcompiled_function): Now static.
16235 * window.c (window_body_lines): Now static.
16237 * image.c (gif_load): Rename local to avoid shadowing.
16239 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
16240 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
16241 * alloc.c (make_save_value): Integer argument is now of type
16242 ptrdiff_t, not int.
16243 (mark_object): Use ptrdiff_t, not int.
16244 * lisp.h (pD): New macro.
16245 * print.c (print_object): Use it.
16247 * alloc.c: Use EMACS_INT, not int, to count objects.
16248 (total_conses, total_markers, total_symbols, total_vector_size)
16249 (total_free_conses, total_free_markers, total_free_symbols)
16250 (total_free_floats, total_floats, total_free_intervals)
16251 (total_intervals, total_strings, total_free_strings):
16252 Now EMACS_INT, not int. All uses changed.
16253 (Fgarbage_collect): Compute overall total using a double, so that
16254 integer overflow is less likely to be a problem. Check for overflow
16255 when converting back to an integer.
16256 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
16257 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
16258 These were 'int' variables that could overflow on 64-bit hosts;
16259 they were never used, so remove them instead of repairing them.
16260 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
16261 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
16262 Previously, this ceilinged at INT_MAX, but that doesn't work on
16264 (allocate_pseudovector): Don't use EMACS_INT when int would do.
16266 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
16267 (allocate_vectorlike): Check for ptrdiff_t overflow.
16268 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
16269 when a (possibly-narrower) signed value would do just as well.
16270 We prefer using signed arithmetic, to avoid comparison confusion.
16272 * alloc.c: Catch some string size overflows that we were missing.
16273 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
16274 for convenience in STRING_BYTES_MAX.
16275 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
16276 The definition here is exact; the one in lisp.h was approximate.
16277 (allocate_string_data): Check for string overflow. This catches
16278 some instances we weren't catching before. Also, it catches
16279 size_t overflow on (unusual) hosts where SIZE_MAX <= min
16280 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
16281 and ptrdiff_t and EMACS_INT are both 64 bits.
16283 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
16284 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
16285 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
16287 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
16289 * alloc.c (Fmake_string): Check for out-of-range init.
16291 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
16293 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
16295 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
16297 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
16298 xg_get_default_scrollbar_width.
16300 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
16301 (int_gtk_range_get_value): Move to the scroll bar part of the file.
16302 (style_changed_cb): Call update_theme_scrollbar_width and call
16303 x_set_scroll_bar_default_width and xg_frame_set_char_size for
16304 all frames (Bug#8505).
16305 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
16306 Call gtk_window_set_resizable if HAVE_GTK3.
16307 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
16308 and height if HAVE_GTK3 (Bug#8505).
16309 (scroll_bar_width_for_theme): New variable.
16310 (update_theme_scrollbar_width): New function.
16311 (xg_get_default_scrollbar_width): Move code to
16312 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
16313 (xg_initialize): Call update_theme_scrollbar_width.
16315 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
16317 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
16319 2011-06-12 Martin Rudalics <rudalics@gmx.at>
16321 * frame.c (make_frame): Call other_buffer_safely instead of
16324 * window.c (temp_output_buffer_show): Call display_buffer with
16325 second argument Vtemp_buffer_show_specifiers and reset latter
16326 immediately after the call.
16327 (Vtemp_buffer_show_specifiers): New variable.
16328 (auto_window_vscroll_p, next_screen_context_lines)
16329 (Vscroll_preserve_screen_position): Remove leading asterisks from
16332 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
16334 Fix minor problems found by GCC 4.6.0 static checking.
16335 * buffer.c (Qclone_number): Remove for now, as it's unused.
16336 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
16337 (record_buffer): Remove unused local.
16338 * frame.c (other_visible_frames, frame_buffer_list): Now static.
16339 (set_frame_buffer_list): Remove; unused.
16340 * frame.h (other_visible_frames): Remove decl.
16341 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
16342 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
16343 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
16345 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
16346 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
16347 Define only if HAVE_GPM.
16348 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
16349 (update_hints_inhibit): Remove; never set. All uses removed.
16350 * widgetprv.h (emacsFrameClassRec): Remove decl.
16351 * window.c (delete_deletable_window): Now returns void, since it
16352 wasn't returning anything.
16353 (compare_window_configurations): Remove unused locals.
16354 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
16355 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
16356 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
16357 the same widths as pointers. This follows up on the 2011-05-06 patch.
16358 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
16359 * xterm.h: Likewise.

16365 (LISP_H): Add lib/intprops.h.
16367 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
16369 * image.c (gif_load): Add animation frame delay to the metadata.
16370 (syms_of_image): Use DEFSYM. New symbol `delay'.
16372 2011-06-11 Martin Rudalics <rudalics@gmx.at>
16374 * window.c (delete_deletable_window): Re-add.
16375 (Fset_window_configuration): Rewrite to handle dead buffers and
16376 consequently deletable windows.
16377 (window_tree, Fwindow_tree): Remove. Supply functionality in
16379 (compare_window_configurations): Simplify code.
16381 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
16383 * image.c (imagemagick_load_image): Fix type mismatch.
16384 (Fimagemagick_types): Likewise.
16386 * window.h (replace_buffer_in_windows): Declare.
16388 2011-06-11 Martin Rudalics <rudalics@gmx.at>
16390 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
16391 Qclone_number. Remove external declaration of Qdelete_window.
16392 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
16394 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
16395 Run Qbuffer_list_update_hook if allowed.
16396 (Fother_buffer): Rewrite doc-string. Major rewrite for new
16397 buffer list implementation.
16398 (other_buffer_safely): New function.
16399 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
16400 calls to replace_buffer_in_windows and
16401 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
16403 (record_buffer): Inhibit quitting and rewrite using quittable
16404 functions. Run Qbuffer_list_update_hook if allowed.
16405 (Frecord_buffer, Funrecord_buffer): New functions.
16406 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
16407 Move switch-to-buffer to window.el.
16408 (bury-buffer): Move to window.el.
16409 (Vbuffer_list_update_hook): New variable.
16411 * lisp.h (other_buffer_safely): Add prototype in buffer.c
16414 * window.h (resize_frame_windows): Move up in code.
16415 (Fwindow_frame): Remove EXFUN.
16416 (replace_buffer_in_all_windows): Remove prototype.
16417 (replace_buffer_in_windows_safely): Add prototype.
16419 * window.c: Declare Qdelete_window static again. Move down
16420 declaration of select_count.
16421 (Fnext_window, Fprevious_window): Rewrite doc-strings.
16422 (Fother_window): Move to window.el.
16423 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
16424 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.
16425 (Fdelete_windows_on, Freplace_buffer_in_windows): Move to
16427 (replace_buffer_in_windows): Implement by calling
16428 Qreplace_buffer_in_windows.
16429 (replace_buffer_in_all_windows): Remove with some functionality
16430 moved into replace_buffer_in_windows_safely.
16431 (replace_buffer_in_windows_safely): New function.
16432 (select_window_norecord, select_frame_norecord): Move in front
16433 of run_window_configuration_change_hook. Remove now obsolete
16435 (Fset_window_buffer): Rewrite doc-string.
16436 Call Qrecord_window_buffer.
16437 (keys_of_window): Move binding for other-window to window.el.
16439 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
16441 * dispextern.h (struct image): Replace data member, whose int_val
16442 and ptr_val fields were not used by anything, with a single
16445 * image.c (Fimage_metadata, make_image, mark_image, tiff_load)
16446 (gif_clear_image, gif_load, imagemagick_load_image)
16447 (gs_clear_image, gs_load): Callers changed.

16926 Without this change, the gnutls library would invoke malloc etc.
16927 directly, which causes problems on non-SYNC_INPUT hosts, and which
16928 runs afoul of improving memory_full behavior. (Bug#8761)
16929 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
16930 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
16931 xfree instead of the default malloc, realloc, free.
16932 (Fgnutls_boot): No need to check for memory allocation failure,
16933 since xmalloc does that for us.
16935 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
16936 * category.c (hash_get_category_set):
16937 * ccl.c (ccl_driver):
16938 * charset.c (Fdefine_charset_internal):
16939 * charset.h (struct charset.hash_index):
16940 * composite.c (get_composition_id, gstring_lookup_cache)
16941 (composition_gstring_put_cache):
16942 * composite.h (struct composition.hash_index):
16943 * dispextern.h (struct image.hash):
16944 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
16945 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)

16948 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
16949 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
16950 (Fsxhash, Fgethash, Fputhash, Fmaphash):
16951 * image.c (make_image, search_image_cache, lookup_image)
16952 (xpm_put_color_table_h):
16953 * lisp.h (struct Lisp_Hash_Table):
16954 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
16955 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
16956 for hashes and hash indexes, instead of 'unsigned' and 'int'.
16957 * alloc.c (allocate_vectorlike):
16958 Check for overflow in vector size calculations.
16959 * ccl.c (ccl_driver):
16960 Check for overflow when converting EMACS_INT to int.
16961 * fns.c, image.c: Remove unnecessary static decls that would otherwise
16962 need to be updated by these changes.
16963 * fns.c (make_hash_table, maybe_resize_hash_table):
16964 Check for integer overflow with large hash tables.
16965 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
16966 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
16967 (SXHASH_REDUCE): New macro.
16968 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
16969 Use it instead of discarding useful hash info with large hash values.
16970 (sxhash_float): New function.
16971 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
16972 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
16973 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
16974 Rewrite to use FIXNUM_BITS, as this simplifies things.
16975 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
16976 Adjust signatures to match updated version of code.
16977 (consing_since_gc): Now EMACS_INT, since a single hash table can
16978 use more than INT_MAX bytes.
16980 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
16982 Make it possible to build with GCC-4.6+ -O2 -flto.
16984 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
16986 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
16988 * minibuf.c (get_minibuffer, read_minibuf_unwind):
16989 Call minibuffer-inactive-mode.
16991 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
16993 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
16994 Update dependencies.
16996 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
16998 * data.c (init_data): Remove code for UTS, this system is not
17001 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17003 Don't force ./temacs to start in terminal mode.
17005 * frame.c (make_initial_frame): Initialize faces in all cases, not
17006 only when CANNOT_DUMP is defined.
17007 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
17009 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17011 * dispnew.c (add_window_display_history): Use const for the string
17012 pointer. Remove declaration, not needed.
17014 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
17016 Use 'inline', not 'INLINE'.
17017 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
17018 * alloc.c, fontset.c (INLINE): Remove.
17019 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
17020 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
17021 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
17022 * gmalloc.c (register_heapinfo): Use inline unconditionally.
17023 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
17025 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17027 Make it possible to run ./temacs.
17029 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
17030 syms_of_callproc does the same thing. Remove test for
17031 "initialized", do it in the caller.
17032 * emacs.c (main): Avoid calling set_initial_environment when dumping.
17034 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
17036 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
17037 (read_minibuf): Use get_minibuffer.
17038 (syms_of_minibuf): Use DEFSYM.
17039 (Qmetadata): New var.
17040 * data.c (Qbuffer): Don't make it static.
17041 (syms_of_data): Use DEFSYM.
17043 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
17045 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
17046 (CCL_CODE_MIN): New macro.
17048 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
17050 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
17052 * eval.c (Qdebug): Now static.
17053 * lisp.h (Qdebug): Remove decl. This reverts a part of the
17054 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
17055 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
17057 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
17059 * image.c: Various fixes to ImageMagick code comments.
17060 (Fimagemagick_types): Doc fix.
17062 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
17064 Minor fixes prompted by GCC 4.6.0 warnings.
17066 * xselect.c (converted_selections, conversion_fail_tag): Now static.
17068 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
17069 (x_clipboard_manager_save_all): Move extern decl to ...
17070 * xterm.h: ... here, so that it can be checked for consistency.
17072 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
17074 * xselect.c (x_clipboard_manager_save_frame)
17075 (x_clipboard_manager_save_all): New functions.
17076 (Fx_clipboard_manager_save): Lisp function deleted.
17078 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
17079 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
17081 * xterm.h: Update prototype.
17083 2011-05-28 William Xu <william.xwl@gmail.com>
17085 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
17086 exiting (Bug#8239).
17088 2011-05-28 Jim Meyering <meyering@redhat.com>
17090 Avoid a sign-extension bug in crypto_hash_function.
17091 * fns.c (to_uchar): Define.
17092 (crypto_hash_function): Use it to convert some newly-signed
17093 variables to unsigned, to avoid sign-extension bugs. For example,
17094 without this change, (md5 "truc") would evaluate to
17095 45723a2aff78ff4fff7fff1114760e62 rather than the expected
17096 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
17097 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
17099 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17101 Integer overflow fixes.
17103 * dbusbind.c: Serial number integer overflow fixes.
17104 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
17105 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
17106 to hold a serial number that is too large for a fixnum.
17107 (Fdbus_method_return_internal, Fdbus_method_error_internal):
17108 Check for serial numbers out of range. Decode any serial number
17109 that was so large that it became a float. (Bug#8722)
17111 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
17112 (Fdbus_call_method, Fdbus_call_method_asynchronously):
17113 Use XFASTINT rather than XUINT when numbers are nonnegative.
17114 (xd_append_arg, Fdbus_method_return_internal):
17115 (Fdbus_method_error_internal): Likewise. Also, for unsigned
17116 arguments, check that Lisp number is nonnegative, rather than
17117 silently wrapping negative numbers around. (Bug#8722)
17118 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
17121 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
17123 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
17125 ccl: Add integer overflow checks.
17126 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
17127 (IN_INT_RANGE): New macros.
17128 (ccl_driver): Use them to check for integer overflow when
17129 decoding a CCL program. Many of the new checks are whether XINT (x)
17130 fits in int; it doesn't always, on 64-bit hosts. The new version
17131 doesn't catch all possible integer overflows, but it's an
17132 improvement. (Bug#8719)
17134 * alloc.c (make_event_array): Use XINT, not XUINT.
17135 There's no need for unsigned here.
17137 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
17138 This follows up to the 2011-05-06 change that substituted uintptr_t
17139 for EMACS_INT. This case wasn't caught back then.
17141 Rework Fformat to avoid integer overflow issues.
17142 * editfns.c: Include <float.h> unconditionally, as it's everywhere
17143 now (part of C89). Include <verify.h>.
17144 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
17145 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
17146 (Fformat): Avoid the prepass trying to compute sizes; it was only
17147 approximate and thus did not catch overflow reliably. Instead, walk
17148 through the format just once, formatting and computing sizes as we go,
17149 checking for integer overflow at every step, and allocating a larger
17150 buffer as needed. Keep track separately whether the format is
17151 multibyte. Keep only the most-recently calculated precision, rather
17152 than them all. Record whether each argument has been converted to
17153 string. Use EMACS_INT, not int, for byte and char and arg counts.
17154 Support field widths and precisions larger than INT_MAX. Avoid
17155 sprintf's undefined behavior with conversion specifications such as %#d
17156 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
17157 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
17158 formatting out-of-range floating point numbers with int
17159 formats. (Bug#8668)
17161 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
17163 * data.c: Avoid integer truncation in expressions involving floats.
17164 * data.c: Include <intprops.h>.
17165 (arith_driver): When there's an integer overflow in an expression
17166 involving floating point, convert the integers to floating point
17167 so that the resulting value does not suffer from catastrophic
17168 integer truncation. For example, on a 64-bit host (* 4
17169 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
17170 Do not rely on undefined behavior after integer overflow.
17172 merge count_size_as_multibyte, parse_str_to_multibyte
17173 * character.c, character.h (count_size_as_multibyte):
17174 Rename from parse_str_to_multibyte; all uses changed.
17175 Check for integer overflow.
17176 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
17177 since it's now a duplicate of the other. This is more of
17178 a character than a buffer op, so better that it's in character.c.
17179 * fns.c, print.c: Adjust to above changes.
17181 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
17183 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
17185 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17187 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17188 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
17189 (x_clipboard_manager_save): Now static.
17190 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
17192 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17193 (crypto_hash_function): Now static.
17194 Fix pointer signedness problems. Avoid unnecessary initializations.
17196 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
17198 * termhooks.h (Vselection_alist): Make it terminal-local.
17200 * terminal.c (create_terminal): Initialize it.
17202 * xselect.c: Support for clipboard managers.
17203 (Vselection_alist): Move to termhooks.h as terminal-local var.
17204 (LOCAL_SELECTION): New macro.
17205 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
17206 (symbol_to_x_atom): Remove gratuitous arg.
17207 (x_handle_selection_request, lisp_data_to_selection_data)
17208 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
17209 (x_own_selection, x_get_local_selection, x_convert_selection):
17210 New arg, specifying work frame. Use terminal-local Vselection_alist.
17211 (some_frame_on_display): Delete unused function.
17212 (Fx_own_selection_internal, Fx_get_selection_internal)
17213 (Fx_disown_selection_internal, Fx_selection_owner_p)
17214 (Fx_selection_exists_p): New optional frame arg.
17215 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
17216 (x_handle_selection_clear): Don't treat other terminals with the
17217 same keyboard specially. Use the terminal-local Vselection_alist.
17218 (x_clear_frame_selections): Use Frun_hook_with_args.
17220 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
17222 * xterm.h: Add support for those atoms.
17224 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
17226 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
17227 (converted_selections, conversion_fail_tag): New global variables.
17228 (x_selection_request_lisp_error): Free the above.
17229 (x_get_local_selection): Remove unnecessary code.
17230 (x_reply_selection_request): Args changed; handle arbitrary array
17231 of converted selections stored in converted_selections.
17232 Separate the XChangeProperty and SelectionNotify steps.
17233 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
17234 (x_convert_selection): New function.
17235 (x_handle_selection_event): Simplify.
17236 (x_get_foreign_selection): Don't ignore incoming requests while
17237 waiting for an answer; this will fail when we implement
17238 SAVE_TARGETS, and seems unnecessary anyway.
17239 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
17240 (Vx_sent_selection_functions): Doc fix.
17242 2011-05-26 Leo Liu <sdl.web@gmail.com>
17244 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
17246 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17248 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
17250 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
17251 for fringe update if it has periodic bitmap.
17252 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
17253 and fringe_bitmap_periodic_p.
17255 * fringe.c (get_fringe_bitmap_data): New function.
17256 (draw_fringe_bitmap_1, update_window_fringes): Use it.
17257 (update_window_fringes): Record periodicity of fringe bitmap in glyph
17258 row. Mark glyph row for fringe update if periodicity changed.
17260 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
17261 for fringe update unless it has periodic bitmap.
17263 2011-05-25 Kenichi Handa <handa@m17n.org>

17281 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
17282 Remove macros that are defined and never used.
17283 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
17285 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
17287 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
17288 (Fx_get_selection_internal): Minor cleanup.

17316 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
17318 * systime.h (Time): Define only if emacs is defined.
17319 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
17320 where the include path doesn't have X11/X.h by default. See
17321 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
17323 2011-05-20 Kenichi Handa <handa@m17n.org>
17325 * composite.c (find_automatic_composition): Fix previous change.
17327 2011-05-20 Glenn Morris <rgm@gnu.org>

17338 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
17339 (lisp): Set the order to that of loadup.el.
17340 (shortlisp): Make it a copy of $lisp.
17341 (SOME_MACHINE_LISP): Remove.

17347 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
17348 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
17349 (find_automatic_composition): Mostly rewrite for efficiency.
17351 2011-05-18 Juanma Barranquero <lekktu@gmail.com>

17358 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
17360 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
17362 Fix some integer overflow issues, such as string length overflow.
17364 * insdel.c (count_size_as_multibyte): Check for string overflow.
17366 * character.c (lisp_string_width): Check for string overflow.
17367 Use EMACS_INT, not int, for string indexes and lengths; in
17368 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
17369 the resulting string length overflows an EMACS_INT; instead,
17370 report a string overflow if no precision given. When checking for
17371 precision exhaustion, use a check that cannot possibly have
17372 integer overflow. (Bug#8675)
17373 * character.h (lisp_string_width): Adjust to new signature.
17375 * alloc.c (string_overflow): New function.
17376 (Fmake_string): Use it. This doesn't change behavior, but saves
17377 a few bytes and will simplify future changes.
17378 * character.c (string_escape_byte8): Likewise.
17379 * lisp.h (string_overflow): New decl.
17381 Fixups, following up to the user-interface timestamp change.
17382 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
17383 for UI timestamps, instead of unsigned long.
17384 * msdos.c (mouse_get_pos): Likewise.
17385 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
17386 * w32gui.h (Time): Define by including "systime.h" rather than by
17387 declaring it ourselves. (Bug#8664)
17389 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
17390 * image.c (clear_image_cache): Likewise.
17392 * term.c (term_mouse_position): Don't assume time_t wraparound.
17394 Be more systematic about user-interface timestamps.
17395 Before, the code sometimes used 'Time', sometimes 'unsigned long',
17396 and sometimes 'EMACS_UINT', to represent these timestamps.
17397 This change causes it to use 'Time' uniformly, as that's what X uses.
17398 This makes the code easier to follow, and makes it easier to catch
17399 integer overflow bugs such as Bug#8664.
17400 * frame.c (Fmouse_position, Fmouse_pixel_position):
17401 Use Time, not unsigned long, for user-interface timestamps.
17402 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
17403 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
17404 * keyboard.h (last_event_timestamp): Likewise.
17405 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
17406 * menu.h (xmenu_show): Likewise.
17407 * term.c (term_mouse_position): Likewise.
17408 * termhooks.h (struct input_event.timestamp): Likewise.
17409 (struct terminal.mouse_position_hook): Likewise.
17410 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
17411 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
17412 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
17413 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
17414 what it was before.
17415 * menu.h, termhooks.h: Include "systime.h", for Time.
17417 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
17418 Don't assume that the difference between two unsigned long values
17419 can fit into an integer. At this point, we know button_down_time
17420 <= event->timestamp, so the difference must be nonnegative, so
17421 there's no need to cast the result if double-click-time is
17422 nonnegative, as it should be; check that it's nonnegative, just in
17423 case. This bug is triggered when events are more than 2**31 ms
17424 apart (about 25 days). (Bug#8664)
17426 * xselect.c (last_event_timestamp): Remove duplicate decl.
17427 (x_own_selection): Remove needless cast to unsigned long.
17429 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
17430 that always fit in int. Use a sentinel instead of a counter, to
17431 avoid a temp and to allay GCC's concerns about possible int overflow.
17432 * frame.h (struct frame): Use int for menu_bar_items_used
17433 instead of EMACS_INT, since it always fits in int.
17435 * menu.c (grow_menu_items): Check for int overflow.
17437 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
17439 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
17440 Before, the code was not consistent. These values cannot exceed
17441 2**31 - 1 so there's no need to make them unsigned.
17442 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
17443 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
17444 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
17446 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
17448 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
17449 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
17450 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
17451 presumably because the widths might not match.
17453 * window.c (size_window): Avoid needless test at loop start.
17455 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
17457 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
17459 2011-05-12 Drew Adams <drew.adams@oracle.com>
17461 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
17463 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17465 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
17466 `width' to `bar_area_x' and `bar_area_width', respectively.
17467 (x_scroll_run): Take account of fringe background extension.
17469 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
17470 Rename local vars `left' and `width' to `bar_area_x' and
17471 `bar_area_width', respectively.
17472 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
17473 background extension.
17475 2011-05-10 Jim Meyering <meyering@redhat.com>
17477 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
17479 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
17481 * image.c (Finit_image_library): Return t for built-in image types,
17482 like pbm and xbm. (Bug#8640)
17484 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
17486 * w32menu.c (set_frame_menubar): Fix submenu allocation.
17488 2011-05-07 Eli Zaretskii <eliz@gnu.org>
17490 * w32console.c (Fset_screen_color): Doc fix.
17491 (Fget_screen_color): New function.
17492 (syms_of_ntterm): Defsubr it.
17494 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
17495 unlink the temporary file if Fcall_process didn't create it in the
17497 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
17498 child process will be redirected to a file specified with `:file'.
17499 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
17500 cue to call_process_cleanup not to close that handle.
17502 2011-05-07 Ben Key <bkey76@gmail.com>
17504 * makefile.w32-in: The bootstrap-temacs rule now makes use of
17505 one of two shell specific rules, either bootstrap-temacs-CMD or
17506 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
17507 to the previous implementation of the bootstrap-temacs rule.
17508 The bootstrap-temacs-CMD rule is similar to the previous
17509 implementation of the bootstrap-temacs rule except that it
17510 makes use of the ESC_CFLAGS variable instead of the CFLAGS
17513 These changes, along with some changes to nt/configure.bat,
17514 nt/gmake.defs, and nt/nmake.defs, are required to extend my
17515 earlier fix to add support for --cflags and --ldflags options
17516 that include quotes so that it works whether make uses cmd or
17519 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
17521 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
17522 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
17524 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
17525 a string. Handle both cases.
17526 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
17527 (Fdbus_register_method): Use Qinvalid_function.
17529 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
17531 * makefile.w32-in: Update dependencies.
17532 (LISP_H): Add inttypes.h and stdin.h.
17533 (PROCESS_H): Add unistd.h.
17535 2011-05-06 Eli Zaretskii <eliz@gnu.org>
17537 * lread.c: Include limits.h (fixes the MS-Windows build broken by
17538 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
17540 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
17542 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
17544 * term.c (vfatal): Remove stray call to va_end.
17545 It's not needed and the C Standard doesn't allow it here anyway.
17547 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
17548 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
17550 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
17553 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
17555 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
17557 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
17559 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
17561 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
17563 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
17564 * charset.c (Fdefine_charset_internal): Don't initialize
17565 charset.code_space[15]. The value was garbage, on hosts with
17566 32-bit int (Bug#8600).
17568 * lread.c (read_integer): Be more consistent with string-to-number.
17569 Use string_to_number to do the actual conversion; this avoids
17570 rounding errors and fixes some other screwups. Without this fix,
17571 for example, #x1fffffffffffffff was misread as -2305843009213693952.
17572 (digit_to_number): Move earlier, for benefit of read_integer.
17573 Return -1 if the digit is out of range for the base, -2 if it is
17574 not a digit in any supported base. (Bug#8602)
17576 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
17578 * dispnew.c (scrolling_window): Return 1 if we scrolled,
17579 to match comment at start of function. This also removes a
17580 GCC warning about overflow in a 32+64-bit port.
17582 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
17584 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
17585 Reported by Stefan Monnier in
17586 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
17587 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
17588 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
17590 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
17591 (EMACS_UINTPTR): Likewise, with uintptr_t.
17593 * lisp.h: Prefer 64-bit EMACS_INT if available.
17594 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
17595 on 32-bit hosts that have 64-bit int, so that they can access
17597 However, temporarily disable this change unless the temporary
17598 symbol WIDE_EMACS_INT is defined.
17600 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
17602 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
17603 This removes an assumption that EMACS_INT and long are the same
17604 width as pointers. The assumption is true for Emacs porting targets
17605 now, but we want to make other targets possible.
17606 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
17607 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
17608 In the rest of the code, change types of integers that hold casted
17609 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
17610 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
17611 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
17612 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
17613 No need to cast type when ORing.
17614 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
17615 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
17616 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
17617 assume EMACS_INT is the same width as char *.
17618 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
17619 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
17620 Remove no-longer-needed casts.
17621 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
17622 (xg_tool_bar_help_callback, xg_make_tool_item):
17623 Use EMACS_INTPTR to hold an integer
17624 that will be cast to void *; this can avoid a GCC warning
17625 if EMACS_INT is not the same width as void *.
17626 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
17627 * xdisp.c (display_echo_area_1, resize_mini_window_1):
17628 (current_message_1, set_message_1):
17629 Use a local to convert to proper width without a cast.
17630 * xmenu.c (dialog_selection_callback): Likewise.
17632 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
17633 Also, don't assume VALBITS / RAND_BITS is less than 5,
17634 and don't rely on undefined behavior when shifting a 1 left into
17636 * lisp.h (get_random): Change signature to match.
17638 * lread.c (hash_string): Use size_t, not int, for hash computation.
17639 Normally we prefer signed values; but hashing is special, because
17640 it's better to use unsigned division on hash table sizes so that
17641 the remainder is nonnegative. Also, size_t is the natural width
17642 for hashing into memory. The previous code used 'int', which doesn't
17643 retain enough info to hash well into very large tables.
17644 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
17646 * dbusbind.c: Don't possibly lose pointer info when converting.
17647 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
17648 Use XPNTR rather than XHASH, so that the high-order bits of
17649 the pointer aren't lost when converting through void *.
17651 * eval.c (Fautoload): Don't double-shift a pointer.
17653 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
17655 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
17657 * gnutls.c (DEF_GNUTLS_FN):
17658 * image.c (DEF_IMGLIB_FN): Make function pointers static.
17660 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
17662 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
17665 2011-05-05 Eli Zaretskii <eliz@gnu.org>
17667 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
17668 New version that can reserve upto 2GB of heap space.
17670 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
17672 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
17674 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
17676 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
17677 `gnutls_certificate_set_x509_key_file'.
17679 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
17681 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
17682 Update dependencies.
17684 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
17686 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
17687 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
17688 Remove unused parameter `fildes'.
17689 * process.c (read_process_output, send_process): Don't pass it.
17691 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
17693 Fix previous change: the library cache is defined in w32.c.
17694 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
17695 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
17697 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
17699 Implement dynamic loading of GnuTLS on Windows.
17701 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
17702 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
17703 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
17706 * gnutls.c (Qgnutls_dll): Define.
17707 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
17708 (gnutls_*): Declare function pointers.
17709 (init_gnutls_functions): New function to initialize function pointers.
17710 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
17711 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
17712 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
17713 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
17714 (emacs_gnutls_write, emacs_gnutls_read)
17715 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
17716 (Fgnutls_available_p): New function.
17717 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
17718 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
17719 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
17721 * image.c: Include w32.h.
17722 (Vimage_type_cache): Delete.
17723 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
17724 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
17725 (w32_delayed_load): Move to w32.c.
17727 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
17729 * w32.c (QCloaded_from, Vlibrary_cache): Define.
17730 (w32_delayed_load): Move from image.c. When loading a library, record
17731 its filename in the :loaded-from property of the library id.
17732 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
17733 Initialize and staticpro them.
17734 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
17736 * process.c: Include lisp.h before w32.h, not after.
17737 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
17738 instead of gnutls_record_check_pending.
17740 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
17742 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
17744 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
17745 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
17748 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
17750 * xterm.c (x_set_frame_alpha): Do not set property on anything
17751 else than FRAME_X_OUTER_WINDOW (Bug#8608).
17753 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
17755 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
17757 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
17759 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
17760 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

17766 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
17767 (Qgnutls_bootprop_callbacks_verify): Make static.
17769 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
17771 * callproc.c: Indentation fixup.
17773 * sysdep.c (wait_for_termination_1): Make static.
17774 (wait_for_termination, interruptible_wait_for_termination):
17775 Move after wait_for_termination_1.
17777 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
17779 * sysdep.c (interruptible_wait_for_termination): New function
17780 which is like wait_for_termination, but allows keyboard
17783 * callproc.c (Fcall_process): Add (:file "file") as an option for
17785 (Fcall_process_region): Ditto.
17787 2011-04-30 Eli Zaretskii <eliz@gnu.org>
17789 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
17790 rather than `XVECTOR (FOO)->size'.
17792 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
17793 inttypes.h, as a gnulib replacement is used if it not available in
17796 2011-04-21 Eli Zaretskii <eliz@gnu.org>
17798 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
17799 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
17800 of MOST_POSITIVE_FIXNUM. (Bug#8528)
17802 * coding.c (coding_alloc_by_realloc): Error out if destination
17803 will grow beyond MOST_POSITIVE_FIXNUM.
17804 (decode_coding_emacs_mule): Abort if there isn't enough place in
17805 charbuf for the composition carryover bytes. Reserve an extra
17806 space for up to 2 characters produced in a loop.
17807 (decode_coding_iso_2022): Abort if there isn't enough place in
17808 charbuf for the composition carryover bytes.
17810 2011-04-21 Eli Zaretskii <eliz@gnu.org>
17812 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
17813 aborting when %lld or %lll format is passed.
17814 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
17815 %llo or %llx format is passed. (Bug#8545)
17817 * window.c (window_scroll_line_based): Use a marker instead of
17818 simple variables to record original value of point. (Bug#7952)
17820 * doprnt.c (doprnt): Fix the case where a multibyte sequence
17821 produced by %s or %c overflows available buffer space. (Bug#8545)
17823 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
17825 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
17826 (SIZE_MAX): Move defn after all includes, as they might #define it.
17828 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
17830 * w32.c (init_environment): Warn about defaulting HOME to C:\.
17832 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
17834 * keyboard.c (Qdelayed_warnings_hook): Define.
17835 (command_loop_1): Run `delayed-warnings-hook'
17836 if Vdelayed_warnings_list is non-nil.
17837 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
17838 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
17840 2011-04-28 Eli Zaretskii <eliz@gnu.org>
17842 * doprnt.c (doprnt): Don't return value smaller than the buffer
17843 size if the message was truncated. (Bug#8545).
17845 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
17847 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
17848 (Fx_window_property): #if-0 the whole functions, not just the bodies.
17850 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
17852 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
17854 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
17856 * makefile.w32-in: Update dependencies.
17858 2011-04-27 Eli Zaretskii <eliz@gnu.org>
17860 Improve `doprnt' and its usage. (Bug#8545)
17861 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
17862 `format_end'. Remove support for %l as a conversion specifier.
17863 Don't use xrealloc. Improve diagnostics when the %l size modifier
17864 is used. Update the commentary.
17866 * eval.c (verror): Simplify calculation of size_t.
17868 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
17871 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
17873 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
17876 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
17878 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
17879 This makes this file independent of the recent pseudovector change.
17881 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
17883 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
17885 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
17886 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
17887 Remove unused local.
17888 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
17890 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
17891 GCC 4.6.0 optimizes based on type-based alias analysis.
17892 For example, if b is of type struct buffer * and v of type struct
17893 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
17894 != &v->size, and therefore "v->size = 1; b->size = 2; return
17895 v->size;" must therefore return 1. This assumption is incorrect
17896 for Emacs, since it type-puns struct Lisp_Vector * with many other
17897 types. To fix this problem, this patch adds a new type struct
17898 vectorlike_header that documents the constraints on layout of vectors
17899 and pseudovectors, and helps optimizing compilers not get fooled
17900 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
17901 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
17902 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
17904 (XSETPVECTYPE): Rewrite in terms of new macro.
17905 (XSETPVECTYPESIZE): New macro, specifying both type and size.
17906 This is a bit clearer, and further avoids the possibility of
17907 undesirable aliasing.
17908 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
17909 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
17910 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
17911 since Lisp_Subr is a special case (no "next" field).
17912 (ASIZE): Now uses header.size rather than size.
17913 All previous uses of XVECTOR (foo)->size replaced to use this macro,
17914 to avoid the hassle of writing XVECTOR (foo)->header.size.
17915 (struct vectorlike_header): New type.
17916 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
17917 object, to help avoid aliasing.
17918 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
17919 (SUBRP): Likewise, since Lisp_Subr is a special case.
17920 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
17921 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
17922 (struct Lisp_Hash_Table): Combine first two members into a single
17923 struct vectorlike_header member. All uses of "size" and "next" members
17924 changed to be "header.size" and "header.next".
17925 * buffer.h (struct buffer): Likewise.
17926 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
17927 * frame.h (struct frame): Likewise.
17928 * process.h (struct Lisp_Process): Likewise.
17929 * termhooks.h (struct terminal): Likewise.
17930 * window.c (struct save_window_data, struct saved_window): Likewise.
17931 * window.h (struct window): Likewise.
17932 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
17933 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
17934 * buffer.c (init_buffer_once): Likewise.
17935 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
17937 * process.c (Fformat_network_address): Use local var for size,
17940 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
17942 Make the Lisp reader and string-to-float more consistent (Bug#8525)
17943 * data.c (atof): Remove decl; no longer used or needed.
17944 (digit_to_number): Move to lread.c.
17945 (Fstring_to_number): Use new string_to_number function, to be
17946 consistent with how the Lisp reader treats infinities and NaNs.
17947 Do not assume that floating-point numbers represent EMACS_INT
17948 without losing information; this is not true on most 64-bit hosts.
17949 Avoid double-rounding errors, by insisting on integers when
17950 parsing non-base-10 numbers, as the documentation specifies.
17951 * lisp.h (string_to_number): New decl, replacing ...
17952 (isfloat_string): Remove.
17953 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
17954 (read1): Do not accept +. and -. as integers; this
17955 appears to have been a coding error. Similarly, do not accept
17956 strings like +-1e0 as floating point numbers. Do not report
17957 overflow for integer overflows unless the base is not 10 which
17958 means we have no simple and reliable way to continue.
17959 Break out the floating-point parsing into a new
17960 function string_to_number, so that Fstring_to_number parses
17961 floating point numbers consistently with the Lisp reader.
17962 (digit_to_number): Move here from data.c. Make it static inline.
17963 (E_CHAR, EXP_INT): Remove, replacing with ...
17964 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
17965 (string_to_number): New function, replacing isfloat_string.
17966 This function checks for valid syntax and produces the resulting
17967 Lisp float number too. Rework it so that string-to-number
17968 no longer mishandles examples like "1.0e+". Use strtoumax,
17969 so that overflow for non-base-10 numbers is reported only when
17970 there's no portable and simple way to convert to floating point.
17972 * textprop.c (set_text_properties_1): Rewrite for clarity,
17973 and to avoid GCC warning about integer overflow.
17975 * intervals.h (struct interval): Use EMACS_INT for members
17976 where EMACS_UINT might cause problems. See
17977 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
17978 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
17979 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
17981 (offset_intervals): Tell GCC not to worry about length overflow
17982 when negating a negative length.
17984 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
17985 (overrun_check_free): Likewise.
17987 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
17988 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
17991 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
17992 (gnutls_make_error): Rename local to avoid shadowing.
17993 (gnutls_emacs_global_deinit): ifdef out; not used.
17994 (Fgnutls_boot): Use const for pointer to readonly storage.
17995 Comment out unused local. Fix pointer signedness problems.
17997 * lread.c (openp): Don't stuff size_t into an 'int'.
17998 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
17999 about possible signed overflow.
18001 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18002 (GDK_KEY_g): Don't define if already defined.
18003 (xg_prepare_tooltip): Avoid pointer signedness problem.
18004 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
18006 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
18007 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
18009 * xfns.c (Fx_window_property): Simplify a bit,
18010 to make a bit faster and to avoid GCC 4.6.0 warning.
18011 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
18013 * fns.c (internal_equal): Don't assume size_t fits in int.
18015 * alloc.c (compact_small_strings): Tighten assertion a little.
18017 Replace pEd with more-general pI, and fix some printf arg casts.
18018 * lisp.h (pI): New macro, generalizing old pEd macro to other
18019 conversion specifiers. For example, use "...%"pI"d..." rather
18020 than "...%"pEd"...".
18021 (pEd): Remove. All uses replaced with similar uses of pI.
18022 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
18023 * alloc.c (check_pure_size): Don't overflow by converting size to int.
18024 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
18025 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
18026 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
18027 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
18028 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
18030 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
18031 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
18032 * print.c (safe_debug_print, print_object): Likewise.
18033 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
18035 Use pI instead of if-then-else-abort. Use %p to avoid casts,
18036 avoiding the 0 flag, which is not portable.
18037 * process.c (Fmake_network_process): Use pI to avoid cast.
18038 * region-cache.c (pp_cache): Likewise.
18039 * xdisp.c (decode_mode_spec): Likewise.
18040 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
18041 behavior on 64-bit hosts with printf arg.
18042 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
18043 (x_stop_queuing_selection_requests): Likewise.
18044 (x_get_window_property): Don't truncate byte count to an 'int'
18047 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
18048 here, since it parses constructs like leading '-' and spaces,
18049 which are not wanted; and it overflows with large numbers.
18050 Instead, simply match F[0-9]+, which is what is wanted anyway.
18052 * alloc.c: Remove unportable assumptions about struct layout.
18053 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
18054 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
18055 (allocate_vectorlike, make_pure_vector): Use the new macros,
18056 plus offsetof, to remove unportable assumptions about struct layout.
18057 These assumptions hold on all porting targets that I know of, but
18058 they are not guaranteed, they're easy to remove, and removing them
18059 makes further changes easier.
18061 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
18062 This doesn't fix a bug but makes the code clearer.
18063 (string_overrun_cookie): Now const. Use initializers that
18064 don't formally overflow signed char, to avoid warnings.
18065 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
18066 can cause Emacs to crash when string overrun checking is enabled.
18067 (allocate_buffer): Don't assume sizeof (struct buffer) is a
18068 multiple of sizeof (EMACS_INT); it need not be, if
18069 alignof(EMACS_INT) < sizeof (EMACS_INT).
18070 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
18072 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
18074 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
18076 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
18078 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
18079 supposed to be handshaking. (Bug#8556)
18080 Reported by Paul Eggert <eggert@cs.ucla.edu>.
18082 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
18084 * lisp.h (Qdebug): List symbol.
18085 * eval.c (Qdebug): Restore global linkage.
18086 * keyboard.c (debug-on-event): New variable.
18087 (handle_user_signal): Break into debugger when debug-on-event
18088 matches the current signal symbol.
18090 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
18092 * alloc.c (check_sblock, check_string_bytes)
18093 (check_string_free_list): Convert to standard C.
18095 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
18097 * w32.c (emacs_gnutls_push): Fix typo.
18099 2011-04-25 Eli Zaretskii <eliz@gnu.org>
18101 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
18102 "cast to pointer from integer of different size".
18104 Improve doprnt and its use in verror. (Bug#8545)
18105 * doprnt.c (doprnt): Document the set of format control sequences
18106 supported by the function. Use SAFE_ALLOCA instead of always
18109 * eval.c (verror): Don't limit the buffer size at size_max-1, that
18110 is one byte too soon. Don't use xrealloc; instead xfree and
18113 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
18115 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
18118 * gnutls.c: Renamed global_initialized to
18119 gnutls_global_initialized. Added internals for the
18120 :verify-hostname-error, :verify-error, and :verify-flags
18121 parameters of `gnutls-boot' and documented those parameters in the
18122 docstring. Start callback support.
18123 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
18124 unless a fatal error occurred. Call gnutls_alert_send_appropriate
18125 on error. Return error code.
18126 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
18127 (emacs_gnutls_read): Likewise.
18128 (Fgnutls_boot): Return handshake error code.
18129 (emacs_gnutls_handle_error): New function.
18130 (wsaerror_to_errno): Likewise.

18135 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
18136 (emacs_gnutls_push): Likewise.
18138 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
18140 * process.c (wait_reading_process_output): Check if GnuTLS
18141 buffered some data internally if no FDs are set for TLS
18144 * makefile.w32-in (OBJ2): Add gnutls.$(O).
18145 (LIBS): Link to USER_LIBS.

18151 display_replaced_before_p argument into display_replaced_p, to
18152 make it consistent with the commentary. Fix typos in the

18167 to changes in oldXMenu/XMenu.h from 2011-04-16.
18168 (struct XMenu): Declare `help_text' `const char **'.

18185 changes in globals.h immediately force recompilation.
18186 (TAGS): Depend on $(CURDIR)/m/intel386.h and
18187 $(CURDIR)/s/ms-w32.h.
18188 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.

18191 (syms_of_character): Don't defsubr it.
18192 <char-direction-table>: Deleted.
18194 2011-04-23 Eli Zaretskii <eliz@gnu.org>
18196 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
18197 * doprnt.c: Include limits.h.
18198 (SIZE_MAX): New macro.
18199 (doprnt): Return a size_t value. 2nd arg is now size_t.
18200 Many local variables are now size_t instead of int or unsigned.
18201 Improve overflow protection. Support `l' modifier for integer
18202 conversions. Support %l conversion. Don't assume an EMACS_INT
18203 argument for integer conversions and for %c.
18205 * lisp.h (doprnt): Restore prototype.
18207 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
18208 $(SRC)/character.h.
18210 * Makefile.in (base_obj): Add back doprnt.o.
18212 * deps.mk (doprnt.o): Add back prerequisites.
18213 (callint.o): Depend on character.h.
18215 * eval.c (internal_lisp_condition_case): Include the handler

18430 ns_descriptor_to_entity that were caused by using free to
18431 deallocate memory blocks that were allocated by xmalloc (via

18452 (emacs_read, emacs_write): Use it.
18453 * process.c (send_process): Adjust to the new signatures of
18454 emacs_write and emacs_gnutls_write. Do not attempt to store

18682 * xterm.c: Make symbols static if they're not exported.
18683 (x_raise_frame, x_lower_frame, x_wm_set_window_state):

18783 * casetab.c (Vascii_upcase_table, Vascii_eqv_table): Now static.
18784 * lisp.h: Remove these decls.
18786 * buffer.c (buffer_count): Remove unused var.
18788 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
18789 so that it's not optimized away.
18790 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
18791 * dispextern.h (bidi_dump_cached_states): Remove, since it's
18792 exported only to the debugger.

18795 * atimer.h (run_all_atimers): Remove; not exported.
18797 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
18798 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
18799 was inaccessible from Lisp.
18800 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
18801 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
18803 alloc.c: Import and export fewer symbols, and remove unused items.
18804 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
18806 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
18807 it's not optimized away by whole-program optimization.

18819 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
18820 (mark_backtrace): Define only if BYTE_MARK_STACK.
18821 * xdisp.c (message_enable_multibyte): Now static.
18823 Declare Lisp_Object Q* variables to be 'static' if not exported.
18824 This makes it easier for human readers (and static analyzers)
18825 to see whether these variables are used from other modules.
18826 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
18827 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:

18835 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
18836 Remove decls of unexported vars.
18837 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
18839 * lisp.h (DEFINE_FUNC): Make sname 'static'.
18841 Make Emacs functions such as Fatom 'static' by default.
18842 This makes it easier for human readers (and static analyzers)
18843 to see whether these functions can be called from other modules.
18844 DEFUN now defines a static function. To make the function external
18845 so that it can be used in other C modules, use the new macro DEFUE.
18846 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
18847 (Finit_image_library):
18848 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
18849 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
18850 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
18851 Remove decls, since these functions are now static.
18852 (Funintern, Fget_internal_run_time): New decls, since these functions
18853 were already external.
18855 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
18856 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

18862 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
18863 Mark functions with DEFUE instead of DEFUN,
18864 if they are used in other modules.
18865 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
18866 decls for now-static functions.
18867 * buffer.h (Fdelete_overlay): Remove decl.
18868 * callproc.c (Fgetenv_internal): Mark as internal.
18869 * composite.c (Fremove_list_of_text_properties): Remove decl.

18875 (Funintern): Remove extern decl; now in .h file where it belongs.
18876 * fileio.c (Fmake_symbolic_link): New forward static decl.
18877 * image.c (Finit_image_library): New forward static decl.
18878 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
18879 * intervals.h (Fprevious_property_change):
18880 (Fremove_list_of_text_properties): Remove decls.
18881 * keyboard.c (Fthis_command_keys): Remove decl.
18882 (Fcommand_execute): New forward static decl.
18883 * keymap.c (Flookup_key): New forward static decl.
18884 (Fcopy_keymap): Now static.
18885 * keymap.h (Flookup_key): Remove decl.
18886 * process.c (Fget_process): New forward static decl.
18887 (Fprocess_datagram_address): Mark as internal.

18898 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
18900 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
18903 2011-04-13 Eli Zaretskii <eliz@gnu.org>
18905 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
18906 when at ZV. (Bug#8487)
18908 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
18910 * charset.c (Fclear_charset_maps): Use xfree instead of free.
18912 * keyboard.c (parse_tool_bar_item): Likewise.
18913 * sound.c (sound_cleanup, alsa_close): Likewise.
18914 * termcap.c (tgetent): Likewise.
18915 * xfns.c (x_default_font_parameter): Likewise.
18916 * xsettings.c (read_and_apply_settings): Likewise.
18918 * alloc.c (overrun_check_malloc, overrun_check_realloc)
18919 (overrun_check_free): Protoize.
18921 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
18923 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
18924 since callers should never pass a negative size.
18925 Change the signature to match that of plain 'read' and 'write'; see
18926 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
18927 * lisp.h: Update prototypes of emacs_write and emacs_read.
18929 2011-04-11 Eli Zaretskii <eliz@gnu.org>
18931 * xdisp.c (redisplay_window): Don't try to determine the character
18932 position of the scroll margin if the window start point w->startp
18933 is outside the buffer's accessible region. (Bug#8468)
18935 2011-04-10 Eli Zaretskii <eliz@gnu.org>
18937 Fix write-region and its subroutines for buffers > 2GB.
18938 * fileio.c (a_write, e_write): Modify declaration of arguments and
18939 local variables to support buffers larger than 2GB.
18940 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
18942 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
18943 argument, local variables, and return value.
18945 * lisp.h: Update prototypes of emacs_write and emacs_read.
18947 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
18949 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
18951 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
18953 Fix more problems found by GCC 4.6.0's static checks.
18955 * xdisp.c (vmessage): Use a better test for character truncation.
18957 * charset.c (load_charset_map): <, not <=, for optimization,
18958 and to avoid potential problems with integer overflow.
18959 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
18960 * casetab.c (set_identity, shuffle): Likewise.
18961 * editfns.c (Fformat): Likewise.
18962 * syntax.c (skip_chars): Likewise.
18964 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
18965 This also lets GCC 4.6.0 generate slightly better loop code.
18967 * callint.c (Fcall_interactively): <, not <=, for optimization.
18968 (Fcall_interactively): Count the number of arguments produced,
18969 not the number of arguments given. This is simpler and lets GCC
18970 4.6.0 generate slightly better code.
18972 * ftfont.c: Distingish more carefully between FcChar8 and char.
18973 The previous code passed unsigned char * to a functions like
18974 strlen and xstrcasecmp that expect char *, which does not
18975 conform to the C standard.
18976 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
18977 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
18978 char * when the C standard requires it.
18980 * keyboard.c (read_char): Remove unused var.
18982 * eval.c: Port to Windows vsnprintf (Bug#8435).
18983 Include <limits.h>.
18984 (SIZE_MAX): Define if the headers do not.
18985 (verror): Do not give up if vsnprintf returns a negative count.
18986 Instead, grow the buffer. This ports to Windows vsnprintf, which
18987 does not conform to C99. Problem reported by Eli Zaretskii.
18988 Also, simplify the allocation scheme, by avoiding the need for
18989 calling realloc, and removing the ALLOCATED variable.
18991 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
18993 Remove invocations of doprnt, as Emacs now uses vsnprintf.
18994 But keep the doprint source code for now, as we might revamp it
18995 and use it again (Bug#8435).
18996 * lisp.h (doprnt): Remove.
18997 * Makefile.in (base_obj): Remove doprnt.o.
18998 * deps.mk (doprnt.o): Remove.
19000 error: Print 32- and 64-bit integers portably (Bug#8435).
19001 Without this change, on typical 64-bit hosts error ("...%d...", N)
19002 was used to print both 32- and 64-bit integers N, which relied on
19003 undefined behavior.
19004 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
19005 * lisp.h (error, verror): Mark as printf-like functions.
19006 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
19007 Report overflow in size calculations when allocating printf buffer.
19008 Do not truncate output string at its first null byte.
19009 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
19010 Truncate the output at a character boundary, since vsnprintf does not
19012 * charset.c (check_iso_charset_parameter): Convert internal
19013 character to string before calling 'error', since %c now has the
19015 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
19016 overflow when computing char to be passed to 'error'. Do not
19017 pass Lisp_Object to 'error'; pass the integer instead.
19018 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
19019 formatted with plain %d.
19021 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
19023 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
19025 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
19027 * xterm.c (x_catch_errors): Remove duplicate declaration.
19029 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
19031 * xdisp.c, lisp.h (message_nolog): Remove; unused.
19033 2011-04-10 Jim Meyering <meyering@redhat.com>
19035 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
19036 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
19037 return ssize_t not "int", and use size_t as the buffer length.
19038 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
19039 * gnutls.h: Update declarations.
19040 * process.c (read_process_output): Use ssize_t, to match.
19041 (send_process): Likewise.
19043 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19045 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
19047 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19049 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
19050 Use unsigned char, to match FcChar8 type definition.
19052 * xterm.c (handle_one_xevent):
19053 * xmenu.c (create_and_show_popup_menu):
19054 * xselect.c (x_decline_selection_request)
19055 (x_reply_selection_request): Avoid type-punned deref of X events.
19057 2011-04-09 Eli Zaretskii <eliz@gnu.org>
19059 Fix some uses of `int' instead of EMACS_INT.
19060 * search.c (string_match_1, fast_string_match)
19061 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
19062 (scan_buffer, find_next_newline_no_quit)
19063 (find_before_next_newline, search_command, Freplace_match)
19064 (Fmatch_data): Make some `int' variables be EMACS_INT.
19066 * xdisp.c (display_count_lines): 3rd argument and return value now
19067 EMACS_INT. All callers changed.
19068 (pint2hrstr): Last argument is now EMACS_INT.
19070 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
19071 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)

19078 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)

19087 (encode_invocation_designation): Last argument P_NCHARS is now
19089 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
19090 (produce_chars): from_nchars and to_nchars are now EMACS_INT.

19113 instead of using internal_with_output_to_temp_buffer.
19114 (Qhelp_form_show): New var.
19115 (syms_of_keyboard): Use DEFSYM macro.
19117 * print.c (internal_with_output_to_temp_buffer): Function deleted.

19130 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
19132 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>

19140 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
19142 * xdisp.c (vmessage): Mark as a printf-like function.
19144 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.

19151 to system-supplied API.
19153 * eval.c (Fsignal): Remove excess argument to 'fatal'.
19155 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
19156 This avoids several warnings with gcc -Wstrict-overflow.
19157 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
19158 directly, rather than having caller test rule sign. This avoids
19159 some unnecessary tests.
19160 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
19161 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
19162 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
19164 * xfont.c (xfont_text_extents): Remove var that was set but not used.
19165 (xfont_open): Avoid unnecessary tests.
19167 * composite.c (composition_gstring_put_cache): Use unsigned integer.
19169 * composite.h, composite.c (composition_gstring_put_cache):
19170 Use EMACS_INT, not int, for length.
19172 * composite.h (COMPOSITION_DECODE_REFS): New macro,
19173 breaking out part of COMPOSITION_DECODE_RULE.
19174 (COMPOSITION_DECODE_RULE): Use it.
19175 * composite.c (get_composition_id): Remove unused local vars,
19176 by using the new macro.
19178 * textprop.c (set_text_properties_1): Change while to do-while,
19179 since the condition is always true at first.
19181 * intervals.c (graft_intervals_into_buffer): Mark var as used.
19182 (interval_deletion_adjustment): Return unsigned value.
19185 * process.c (list_processes_1, create_pty, read_process_output):
19186 (exec_sentinel): Remove vars that were set but not used.
19187 (create_pty): Remove unnecessary "volatile"s.
19188 (Fnetwork_interface_info): Avoid possibility of int overflow.
19189 (read_process_output): Do adaptive read buffering even if carryover.
19190 (read_process_output): Simplify nbytes computation if buffered.
19192 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
19194 * syntax.c (scan_words): Remove var that was set but not used.
19195 (update_syntax_table): Use unsigned instead of int.
19197 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
19198 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
19199 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
19201 * print.c (print_error_message): Avoid int overflow.
19203 * font.c (font_list_entities): Redo for clarity,
19204 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
19206 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
19207 (font_score): Avoid potential overflow in diff calculation.
19209 * fns.c (substring_both): Remove var that is set but not used.
19210 (sxhash): Redo loop for clarity and to avoid wraparound warning.
19212 * eval.c (funcall_lambda): Rename local to avoid shadowing.
19214 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
19215 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
19216 can always succeed if overflow has undefined behavior.
19218 * search.c (boyer_moore, wordify): Remove vars set but not used.
19219 (wordify): Omit three unnecessary tests.
19221 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
19222 All callers changed. This avoids the need for an unused var.
19224 * casefiddle.c (casify_region): Remove var that is set but not used.
19226 * dired.c (file_name_completion): Remove var that is set but not used.
19228 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
19230 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
19231 (Finsert_file_contents): Remove unnecessary code checking fd.
19233 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
19234 Check for integer overflow on size calculations.
19236 * buffer.c (Fprevious_overlay_change): Remove var that is set
19239 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
19240 Remove vars that are set but not used.
19241 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
19242 (timer_check_2): Mark vars as initialized.
19244 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
19246 * image.c (lookup_image): Remove var that is set but not used.
19247 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
19249 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
19250 that are set but not used.
19252 * xfns.c (make_invisible_cursor): Don't return garbage
19253 if XCreateBitmapFromData fails (Bug#8410).
19255 * xselect.c (x_get_local_selection, x_handle_property_notify):
19256 Remove vars that are set but not used.
19258 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
19259 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
19261 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
19262 Remove var that is set but not used.
19263 (scroll_bar_windows_size): Now size_t, not int.
19264 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
19265 Check for overflow.
19267 * xfaces.c (realize_named_face): Remove vars that are set but not used.
19268 (map_tty_color) [!defined MSDOS]: Likewise.
19270 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
19272 * coding.c: Remove vars that are set but not used.
19273 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
19274 All callers changed.
19275 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
19276 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
19277 (decode_coding_charset): Remove vars that are set but not used.
19279 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
19280 that is set but not used.
19282 * print.c (print_object): Remove var that is set but not used.
19284 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
19285 The gnulib version avoids calling malloc in the usual case,
19286 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
19287 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
19288 * filelock.c (current_lock_owner): Likewise.
19289 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
19290 * sysdep.c: Include allocator.h, careadlinkat.h.
19291 (emacs_no_realloc_allocator): New static constant.
19292 (emacs_readlink): New function.
19293 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
19294 ../lib/careadlinkat.h.
19296 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
19298 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
19299 first non-nil return value).
19301 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
19303 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
19304 if not defined (Bug#8403).
19306 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
19308 * xdisp.c (display_count_lines): Remove parameter `start',
19309 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
19310 (get_char_face_and_encoding): Remove parameter `multibyte_p',
19311 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

19313 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
19314 and thereabouts. All callers changed.
19315 (get_per_char_metric): Remove parameter `f', unused since
19316 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
19318 2011-04-02 Jim Meyering <meyering@redhat.com>
19320 do not dereference NULL upon failed strdup
19321 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
19322 (ns_get_family): Likewise.
19324 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
19326 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
19328 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
19330 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
19333 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
19335 Add lexical binding.
19337 * window.c (Ftemp_output_buffer_show): New fun.
19338 (Fsave_window_excursion):
19339 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
19341 * lread.c (lisp_file_lexically_bound_p): New function.
19342 (Fload): Bind Qlexical_binding.
19343 (readevalloop): Remove `evalfun' arg.
19344 Bind Qinternal_interpreter_environment.
19345 (Feval_buffer): Bind Qlexical_binding.
19346 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
19348 (syms_of_lread): Declare `lexical-binding'.
19350 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
19352 * keyboard.c (eval_dyn): New fun.
19353 (menu_item_eval_property): Use it.
19355 * image.c (parse_image_spec): Use Ffunctionp.
19357 * fns.c (concat, mapcar1): Accept byte-code-functions.
19359 * eval.c (Fsetq): Handle lexical vars.
19360 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
19361 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
19362 (FletX, Flet): Obey lexical binding.
19363 (Fcommandp): Handle closures.
19364 (Feval): New `lexical' arg.
19365 (eval_sub): New function extracted from Feval. Use it almost
19366 everywhere where Feval was used. Look up vars in lexical env.
19368 (Ffunctionp): Move from subr.el.
19369 (Ffuncall): Handle closures.
19370 (apply_lambda): Remove `eval_flags'.
19371 (funcall_lambda): Handle closures and new byte-code-functions.
19372 (Fspecial_variable_p): New function.
19373 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
19374 but without exporting it to Lisp.
19376 * doc.c (Fdocumentation, store_function_docstring):
19377 * data.c (Finteractive_form): Handle closures.
19379 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
19382 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
19384 (exec_byte_code): New function extracted from Fbyte_code to handle new
19385 calling convention for byte-code-functions. Add new byte-codes.
19387 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
19389 * alloc.c (Fmake_symbol): Init new `declared_special' field.
19391 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
19393 * xdisp.c (redisplay_internal): Fix prototype.
19395 2011-03-31 Eli Zaretskii <eliz@gnu.org>
19397 * xdisp.c (SCROLL_LIMIT): New macro.
19398 (try_scrolling): Use it when setting scroll_limit.
19399 Limit scrolling to 100 screen lines.
19400 (redisplay_window): Even when falling back on "recentering",
19401 position point in the window according to scroll-conservatively,
19402 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
19404 (try_scrolling): When point is above the window, allow searching
19405 as far as scroll_max, or one screenful, to compute vertical
19406 distance from PT to the scroll margin position. This prevents
19407 try_scrolling from unnecessarily failing when
19408 scroll-conservatively is set to a value slightly larger than the
19409 window height. Clean up the case of PT below the margin at bottom
19410 of window: scroll_max can no longer be INT_MAX. When aggressive
19411 scrolling is in use, don't let point enter the opposite scroll
19412 margin as result of the scroll.
19413 (syms_of_xdisp) <scroll-conservatively>: Document the
19414 threshold of 100 lines for never-recentering scrolling.
19416 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
19418 * dispextern.h (move_it_by_lines):
19419 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
19420 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
19421 (message_log_check_duplicate): Remove parameters `prev_bol' and
19422 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
19423 (redisplay_internal): Remove parameter `preserve_echo_area',
19424 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
19426 * indent.c (Fvertical_motion):
19427 * window.c (window_scroll_pixel_based, Frecenter):
19428 Don't pass `need_y_p' to `move_it_by_lines'.
19430 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
19432 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
19433 steal a few bits to be more compact.
19434 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
19435 Remove unneeded casts.
19437 * bytecode.c (Fbyte_code): CAR and CDR can GC.
19439 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
19441 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
19442 binding" message (bug#7967).
19444 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
19446 Fix more problems found by GCC 4.6.0's static checks.
19448 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
19449 Remove unused local var.
19451 * editfns.c (Fmessage_box): Remove unused local var.
19453 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
19454 (note_mode_line_or_margin_highlight, note_mouse_highlight):
19455 Omit unused local vars.
19456 * window.c (shrink_windows): Omit unused local var.
19457 * menu.c (digest_single_submenu): Omit unused local var.
19458 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
19459 Omit unused local var.
19461 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
19462 Don't assume string length fits in int.
19463 (keyremap_step, read_key_sequence): Use size_t for sizes.
19464 (read_key_sequence): Don't check last_real_key_start redundantly.
19466 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
19467 instead of alloca (Bug#8344).
19469 * eval.c (Fbacktrace): Don't assume nargs fits in int.
19470 (Fbacktrace_frame): Don't assume nframes fits in int.
19472 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
19474 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
19477 * term.c (produce_glyphless_glyph): Remove unnecessary test.
19479 * cm.c (calccost): Turn while-do into do-while, for clarity.
19481 * keyboard.c (syms_of_keyboard): Use the same style as later
19482 in this function when indexing through an array. This also
19483 works around GCC bug 48267.
19485 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
19487 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
19489 * chartab.c (sub_char_table_ref_and_range): Redo for slight
19490 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
19492 * keyboard.c, keyboard.h (num_input_events): Now size_t.
19493 This avoids undefined behavior on integer overflow, and is a bit
19494 more convenient anyway since it is compared to a size_t variable.
19496 Variadic C functions now count arguments with size_t, not int.
19497 This avoids an unnecessary limitation on 64-bit machines, which
19498 caused (substring ...) to crash on large vectors (Bug#8344).
19499 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
19500 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

19508 * fns.c (concat): Likewise.
19509 * frame.c (x_set_frame_parameters): Likewise.
19510 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
19511 0 if not found, not -1. All callers changed.
19513 * alloc.c (garbage_collect): Don't assume stack size fits in int.
19514 (stack_copy_size): Now size_t, not int.
19515 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
19517 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
19519 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
19520 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
19521 All callers changed.
19523 * lisp.h (multibyte_char_to_unibyte):
19524 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
19525 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
19526 * character.h (CHAR_TO_BYTE8):
19527 * cmds.c (internal_self_insert):
19528 * editfns.c (general_insert_function):
19529 * keymap.c (push_key_description):
19530 * search.c (Freplace_match):
19531 * xdisp.c (message_dolog, set_message_1): All callers changed.
19533 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
19535 * keyboard.c (safe_run_hook_funcall): New function.
19536 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
19537 don't set the hook to nil, but remove the offending function instead.
19538 (Qcommand_hook_internal): Remove, unused.
19539 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
19540 Vcommand_hook_internal.
19542 * eval.c (enum run_hooks_condition): Remove.
19543 (funcall_nil, funcall_not): New functions.

19720 * buffer.c (Fkill_all_local_variables):
19721 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
19723 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
19724 unconditionally since it does the check itself.
19726 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
19728 Fix more problems found by GCC 4.5.2's static checks.
19730 * coding.c (encode_coding_raw_text): Avoid unnecessary test
19731 the first time through the loop, since we know p0 < p1 then.
19732 This also avoids a gcc -Wstrict-overflow warning.
19734 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
19735 leading to a memory leak, possible in functions like
19736 load_charset_map_from_file that can allocate an unbounded number
19737 of objects (Bug#8318).
19739 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
19740 that could (at least in theory) be that large.
19742 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
19743 This is less likely to overflow, and avoids undefined behavior if
19744 overflow does occur. All callers changed. Use strtoul to scan
19745 for the unsigned long integer.
19746 (pint2hrstr): Simplify and tune code slightly.
19747 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

19762 * process.c (Fmake_network_process): Use socklen_t, not int,
19763 where POSIX says socklen_t is required in portable programs.
19764 This fixes a porting bug on hosts like 64-bit HP-UX, where
19765 socklen_t is wider than int (Bug#8277).
19766 (Fmake_network_process, server_accept_connection):
19767 (wait_reading_process_output, read_process_output):
19770 * process.c: Rename or move locals to avoid shadowing.

19780 Make tparam.h and terminfo.c consistent.
19781 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
19782 Include tparam.h instead, since it declares them.
19783 * cm.h (PC): Remove extern decl; tparam.h now does this.
19784 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
19785 * terminfo.c: Include tparam.h, to check interfaces.
19786 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
19787 (tparam): Adjust signature to match interface in tparam.h;
19788 this removes some undefined behavior. Check that outstring and len
19789 are zero, which they always are with Emacs.
19790 * tparam.h (PC, BC, UP): New extern decls.
19792 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
19793 (xftfont_open): Rename locals to avoid shadowing.

19811 (composition_update_it): Mark var as initialized.
19812 (find_automatic_composition): Mark vars as initialized,
19813 with a FIXME (Bug#8290).

19819 (BUF_DEC_POS): Be more systematic about renaming local temporaries
19820 to avoid shadowing.

19832 Fix pointer signedness.
19833 (alsa_choose_format): Remove unused local var.
19834 (wav_play): Initialize a variable to 0, to prevent undefined
19835 behavior (Bug#8278).
19837 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
19839 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
19841 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
19842 clobbering (Bug#8298).
19843 * sysdep.c (sys_subshell): Likewise.
19844 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
19846 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
19847 This should get cleaned up, so that child_setup has the
19848 same signature on all platforms.
19850 * callproc.c (call_process_cleanup): Now static.
19851 (relocate_fd): Rename locals to avoid shadowing.
19853 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
19855 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
19856 not to be necessary, and produces flickering.
19858 2011-03-20 Glenn Morris <rgm@gnu.org>
19860 * config.in: Remove file.
19862 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

20010 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
20011 (GC_STRING_CHARS): Remove; not used.
20012 (Fmemory_limit): Cast sbrk's returned value to char *.
20014 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
20015 avoids undefined behavior in theory.
20017 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
20019 Use functions, not macros, for up- and down-casing (Bug#8254).
20020 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
20021 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
20022 to use the following functions instead of these macros.
20023 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
20024 EMACS_INT, since callers assume the returned value fits in int.
20025 (upcase1): Likewise, for UPCASE_TABLE.
20026 (uppercasep, lowercasep, upcase): New static inline functions.
20027 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

20036 which gcc can warn about.
20037 (regex_compile, re_match_2_internal): Mark locals as initialized.
20038 (RETALLOC_IF): Define only if needed.
20039 (WORDCHAR_P): Likewise. This one is never needed, but is used
20040 only in a comment talking about a compiler bug, so put inside
20041 the #if 0 of that comment.
20042 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
20043 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
20046 * search.c (boyer_moore): Rename locals to avoid shadowing.

20069 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
20070 New macros, so that the caller can use some names other than
20071 gcpro1, gcpro2, etc.
20072 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
20074 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
20075 argument, for consistency with GCPRO2_VAR, etc: it is now the
20076 prefix of the variable, not the variable itself. All uses
20078 * dired.c (directory_files_internal, file_name_completion):
20079 Rename locals to avoid shadowing.
20081 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
20082 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
20083 dired.c's scmp function, had undefined behavior.
20084 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
20085 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
20086 * buffer.h: ... to here, because these macros use current_buffer,
20087 and the new implementation with inline functions needs to have
20088 current_buffer in scope now, rather than later when the macros
20090 (downcase, upcase1): New static inline functions.
20091 (DOWNCASE, UPCASE1): Reimplement using these functions.
20092 This avoids undefined behavior in expressions like
20093 DOWNCASE (x) == DOWNCASE (y), which previously suffered
20094 from race conditions in accessing the global variables
20095 case_temp1 and case_temp2.
20096 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
20097 * lisp.h (case_temp1, case_temp2): Remove their decls.
20098 * character.h (ASCII_CHAR_P): Move from here ...
20099 * lisp.h: ... to here, so that the inline functions mentioned
20100 above can use them.
20102 * dired.c (directory_files_internal_unwind): Now static.
20104 * fileio.c (file_name_as_directory, directory_file_name):
20105 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
20107 (file_name_as_directory): Use const pointers when appropriate.
20108 (Fexpand_file_name): Likewise. In particular, newdir might
20109 point at constant storage, so make it a const pointer.
20110 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
20111 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
20113 (Fset_file_times, Finsert_file_contents, auto_save_error):

20118 to avoid shadowing.
20120 * marker.c (bytepos_to_charpos): Remove; unused.
20122 * lisp.h (verify_bytepos, count_markers): New decls,
20123 so that gcc does not warn that these functions aren't declared.
20125 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
20126 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
20127 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
20128 (copy_text): Remove unused local var.
20130 * filelock.c (within_one_second): Now static.
20131 (lock_file_1): Rename local to avoid shadowing.
20133 * buffer.c (fix_overlays_before): Mark locals as initialized.
20134 (fix_start_end_in_overlays): Likewise. This function should be
20135 simplified by using pointers-to-pointers, but that's a different
20137 (switch_to_buffer_1): Now static.
20138 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
20139 (report_overlay_modification): Rename locals to avoid shadowing.
20141 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
20142 Fix pointer signedness issue.
20143 (sys_subshell): Mark local as volatile if checking for lint,
20144 to suppress a gcc -Wclobbered warning that does not seem to be right.
20145 (MAXPATHLEN): Define only if needed.
20147 * process.c (serial_open, serial_configure): Move decls from here ...
20148 * systty.h: ... to here, so that they can be checked.
20150 * fns.c (get_random, seed_random): Move extern decls from here ...
20151 * lisp.h: ... to here, so that they can be checked.
20153 * sysdep.c (reset_io): Now static.
20154 (wait_for_termination_signal): Remove; unused.
20156 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

20161 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
20162 (describe_map_tree):
20163 Rename locals to avoid shadowing.
20165 * keyboard.c: Declare functions static if they are not used elsewhere.

20314 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
