3 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
4 passed to pint2str and pint2hrstr to be at most the size of the
5 frame's decode_mode_spec_buffer. This avoids crashes with very
6 large values of FIELD_WIDTH argument to decode_mode_spec.

11 Fix a race with verify-visited-file-modtime (Bug#12863).
12 Since at least 1991 Emacs has ignored an mtime difference of no
13 more than one second, but my guess is that this was to work around
14 file system bugs that were fixed long ago. Since the race is
15 causing problems now, let's remove that code.
16 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
17 whose time stamp is off by no more than a second. Insist that the
18 file time stamps match exactly.
20 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
22 * frame.h (struct frame): Convert external_tool_bar member to
23 1-bit unsigned bitfield.
24 * termhooks.h (struct terminal): Remove mouse_moved member since
25 all users are long dead. Adjust comment on mouse_position_hook.
27 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
29 Simplify by using FOR_EACH_FRAME here and there.
30 * frame.c (next_frame, prev_frame, other_visible_frames)

50 Remove, and replace all uses with ...
51 (next_in_free_list, set_next_in_free_list):
52 New functions, which respect C's aliasing rules better.
54 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
56 * window.c (list4i): Rename from 'quad'. All uses changed.
57 Needed because <sys/types.h> defines 'quad' on Solaris 10.
59 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
61 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence

71 2012-11-10 Eli Zaretskii <eliz@gnu.org>
73 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
74 amount when the scroll margins are too large. When scrolling
75 backwards in the buffer, give up if cannot reach point or the
76 scroll margin within a reasonable number of screen lines. Fixes
77 point position in window under scroll-up/down-aggressively when
78 point is positioned many lines beyond the window top/bottom.
81 * ralloc.c (relinquish): If real_morecore fails to return memory
82 to the system, don't crash; instead, leave the last heap
83 unchanged and return. (Bug#12774)
85 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
87 * lisp.h (AUTOLOADP): New macro.
88 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.

96 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
98 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
100 * nsfont.m (Qcondensed, Qexpanded): New variables.
101 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
102 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
104 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
106 Fix recently introduced crash on MS-Windows (Bug#12839).

108 (SCROLL_BAR_VEC_SIZE): Remove.
109 * w32term.c (x_scroll_bar_create): Use VECSIZE.
111 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
113 Tweak last vectorlike_header change.
114 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
115 vectorlike object on the free list. This is introduced to avoid
116 some (but not all) pointer casting and aliasing problems, see
117 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
118 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike

124 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
125 been removed, so remove them here also.
127 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
129 * doc.c (Fdocumentation): Handle new property
130 dynamic-docstring-function to replace the old ad-advice-info.
132 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
134 * fns.c (Qeql, hashtest_eq): Now static.
136 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
138 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
139 * fns.c (hashfn_eq, hashfn_eql, sxhash):
140 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
141 * buffer.c (compare_overlays): Use XLI rather than XHASH.
143 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
145 Use same hash function for hashfn_profiler as for hash_string etc.
146 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
147 * lisp.h (sxhash_combine): New inline function, with the contents
148 of the old SXHASH_COMBINE.
149 * profiler.c (hashfn_profiler): Use it, instead of having a
150 special hash function containing a comparison that always yields 1.
152 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
154 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
155 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
156 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
159 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
161 * image.c (xpm_make_color_table_h): Fix compiler error because
162 make_hash_table changed.
164 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
166 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
168 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
170 Use ad-hoc comparison function for the profiler's hash-tables.
171 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
172 (make_log): Use them.
173 (handle_profiler_signal): Don't inhibit quit any longer since we don't
174 call Fequal any more.
175 (Ffunction_equal): New function.
176 (cmpfn_profiler, hashfn_profiler): New functions.
177 (syms_of_profiler): Initialize them.

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

187 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.
188 (syms_of_fns): Initialize them.

197 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
198 value of w32-scroll-lock-modifier is neither nil nor one of the
199 known key modifiers. (Bug#12806)
201 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
203 Shrink struct vectorlike_header to the only size field.
204 * lisp.h (enum pvec_type): Avoid explicit enum member values.
206 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and

221 (NEXT_IN_FREE_LIST): New macro.
222 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
223 (Fmake_bool_vector): Likewise.

225 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
226 (large_vectors): Change type to struct large_vector.
227 (allocate_vector_from_block): Simplify.
228 (PSEUDOVECTOR_NBYTES): Replace with...
229 (vector_nbytes): ...new function. Adjust users.
230 (sweep_vectors): Adjust processing of large vectors.
231 (allocate_vectorlike): Likewise.
232 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
233 Add easserts. Adjust XSETPVECTYPESIZE usage.
234 (allocate_buffer): Use BUFFER_PVEC_INIT.
235 (live_vector_p): Adjust to match large vector.
236 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
237 * buffer.h (struct buffer): Add next member.
238 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
240 (FOR_EACH_BUFFER): Adjust to match struct buffer change.

246 (xvecsize): New command.
248 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
250 * keyboard.c (event_to_kboard): Do not dereference
251 frame_or_window field of SELECTION_REQUEST_EVENT
252 and SELECTION_CLEAR_EVENT events (Bug#12814).
253 * xterm.h (struct selection_input_event): Adjust comment.
255 2012-11-07 Eli Zaretskii <eliz@gnu.org>
257 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
258 such as Scroll Lock, if the respective keys are treated as
259 function keys, not as modifiers. This avoids destroying non-ASCII
260 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
262 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
264 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
266 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
268 Restore some duplicate definitions (Bug#12814).
269 This undoes part of the 2012-11-03 changes. Some people build
270 with plain -g rather than with -g3, and they need the duplicate
271 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
272 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
273 Define as macros, as well as as enums or as constants.
275 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
277 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
278 to keypad keys (Bug#12816).
280 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
282 Minor adjustments of recently-changed frame functions.
283 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
284 known to be a frame (we're in the FRAMEP branch).
285 * lisp.h (Qframep): Remove decl. frame.h declares this.
286 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
287 since they're meant for Lisp fixnum values.
289 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
291 * window.c (Fwindow_combination_limit): Revert to the only
292 required argument and adjust docstring as suggested in
293 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
294 by Martin Rudalics <rudalics@gmx.at>.
296 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
298 Widely used frame validity and checking functions.
299 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
300 * frame.c (decode_live_frame, decode_any_frame): New functions.
301 (delete_frame, Fredirect_frame_focus, Fframe_parameters)

306 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
307 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
308 (Fframe_focus): Likewise. Allow zero number of arguments.
310 (frame_buffer_list, frame_buffer_predicate): Remove.
311 * lisp.h (frame_buffer_predicate): Remove prototype.
312 * buffer.c (Fother_buffer): Use decode_any_frame.
313 * xdisp.c (Ftool_bar_lines_needed): Likewise.
314 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
315 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
316 (Fclose_font, Ffont_info): Use decode_live_frame.
317 * fontset.c (check_fontset_name): Likewise.

319 * w32fns.c (check_x_frame): Likewise.
320 * window.c (Fminibuffer_window, Fwindow_at)
321 (Fcurrent_window_configuration): Likewise.
322 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
323 Likewise. Allow zero number of arguments. Adjust docstring.
324 * dispnew.c (Fredraw_frame): Likewise.
325 * xfaces.c (frame_or_selected_frame): Remove.
326 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
327 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
328 (Fframe_face_alist): Use decode_live_frame.
329 * xfns.c (check_x_frame): Likewise.
331 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
333 * window.c (quad): New function.
334 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
335 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
336 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
337 (Fwindow_line_height): Use it.
338 (Fwindow_fringes): Use list3.
339 (Fwindow_scroll_bars): Use list4.
340 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
341 (Fwindow_combination_limit): Allow zero number of arguments.
343 2012-11-05 Eli Zaretskii <eliz@gnu.org>
345 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
347 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
348 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
349 file descriptor 2 for standard error. (Bug#12805)
351 2012-11-05 Chong Yidong <cyd@gnu.org>
353 * process.c (wait_reading_process_output): Revert previous change.
355 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
357 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
358 This removes code that has been obsolete since around 1990.
359 * callproc.c (Fcall_process):
361 * process.c (create_process):
362 * term.c (dissociate_if_controlling_tty):
363 Assume setsid exists.
364 * callproc.c (child_setup): Assume setpgid exists and behaves as
365 per POSIX.1-1988 or later.
366 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
367 * emacs.c (shut_down_emacs):
368 * sysdep.c (sys_suspend, init_foreground_group):
369 Assume getpgrp behaves as per POSIX.1-1998 or later.
370 * msdos.c (setpgrp): Remove.
371 (tcgetpgrp, setpgid, setsid): New functions.
372 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
373 * term.c (no_controlling_tty): Remove; unused.
374 * w32proc.c (setpgrp): Remove.
375 (setsid, tcgetpgrp): New functions.
377 Simplify by assuming __fpending.
378 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
379 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
380 Do not assume that __fpending's result fits in int.
382 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
384 Remove EMACS_OUTQSIZE+sleep hack.
385 * dispnew.c (update_frame_1): Remove hack for terminals slower
386 than 2400 bps, which throttled Emacs by having it sleep.
387 This code hasn't worked since at least 2007, when the multi-tty stuff
388 was added, and anyway those old terminals are long dead.
389 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
390 without the dispnew.c change, as dispnew.c doesn't include systty.h.
392 Fix data-loss with --version (Bug#9574).
393 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
394 as we can't assume that emacs_strerror is initialized, and strerror
396 (main): Invoke atexit earlier, to catch earlier instances of
397 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
399 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
401 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
402 (keyDown): Remap keypad keys to X11 virtual key codes.
404 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
406 Fix data-loss with --batch (Bug#9574).
407 * emacs.c: Include <close-stream.h>.
408 (close_output_streams): New function.
409 (main): Pass it to atexit, so that Emacs closes stdout and stderr
410 and handles errors appropriately.
411 (Fkill_emacs): Don't worry about flushing, as close_output_stream
414 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
415 The symptom is a diagnostic "GLib-WARNING **: In call to
416 g_spawn_sync(), exit status of a child process was requested but
417 SIGCHLD action was set to SIG_IGN and ECHILD was received by
418 waitpid(), so exit status can't be returned." The diagnostic
419 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
420 The real bug is a race condition between Emacs and glib: Emacs
421 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
422 so that glib can't find it. Work around the bug by invoking
423 waitpid only on subprocesses that Emacs itself creates.
424 * process.c (create_process, record_child_status_change):
425 Don't use special value -1 in pid field, as the caller now must
426 know the pid rather than having the callee infer it.
427 The inference was sometimes incorrect anyway, due to another race.
428 (create_process): Set new 'alive' member if child is created.
429 (process_status_retrieved): New function.
430 (record_child_status_change): Use it.
431 Accept negative 1st argument, which means to wait for the
432 processes that Emacs already knows about. Move special-case code
433 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
434 processes that have already been waited for, by testing and
435 clearing new 'alive' member.
436 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
437 now does this internally.
438 (handle_child_signal): Let record_child_status_change do all
439 the work, since we do not want to reap all exited child processes,
440 only the child processes that Emacs itself created.
441 * process.h (Lisp_Process): New boolean member 'alive'.
443 Omit duplicate definitions no longer needed with gcc -g3.
444 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
445 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
446 Define only as macros. There's no longer any need to also define
447 these symbols as enums or as constants, since we now assume
448 gcc -g3 when debugging.
450 2012-11-03 Eli Zaretskii <eliz@gnu.org>
452 * lisp.mk: Adjust comments to the fact that term/internal is now
453 loaded from loadup.el.

514 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
516 Window-related stuff cleanup here and there.
517 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):

530 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
532 Remove pad from struct input_event.
533 * termhooks.h (struct input_event): Remove padding field.
535 * keyboard.c (event_to_kboard): Simplify because frame_or_window
536 member is never cons for a long time. Adjust comment.
537 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
538 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
539 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
540 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.

548 Fix crash when using Emacs as commit editor for git (Bug#12697).
549 * callproc.c (setpgrp): Remove macro, as we now use setpgid
550 and it is configured in conf_post.h.
551 (Fcall_process): Don't invoke both setsid and setpgid; the former
552 is enough, if it exists.
553 * callproc.c (Fcall_process, child_setup):
554 * process.c (create_process): Use setpgid.
555 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
557 * dispnew.c (init_display): Initialize the foreground group
558 if we are running a tty display.

571 2012-10-31 Martin Rudalics <rudalics@gmx.at>
573 * minibuf.c (read_minibuf): Restore current buffer since
574 choose_minibuf_frame calling Fset_frame_selected_window may

589 In preparation for fixing bug#12739, move these functions from
592 * coding.h, coding.c: ... to here, and compile them only when
593 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
594 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
596 2012-10-28 Eli Zaretskii <eliz@gnu.org>
598 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.

608 (last_appdefined_event_data): New variable
609 (last_appdefined_event): Remove.
610 (ns_select): Initialize t from last_appdefined_event_data instead
611 of [last_appdefined_event data1].

613 remove last_appdefined_event (Bug#12698).
615 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
617 * frame.c (x_set_font): Catch internal error.
619 2012-10-27 Eli Zaretskii <eliz@gnu.org>
621 Avoid overflow in w32 implementation of interval timers.
622 When possible, for ITIMER_PROF count only times the main thread
624 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
625 'volatile ULONGLONG' types. All the other data which was
626 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
627 (GetThreadTimes_Proc): New typedef.
628 (w32_get_timer_time): New function, returns a suitable time value
630 (timer_loop): Enter critical section when accessing ULONGLONG
631 values of the itimer_data struct, as these accesses are no longer
632 atomic. Call 'w32_get_timer_time' instead of 'clock'.
633 Remove unused variable.
634 (init_timers): Initialize s_pfn_Get_Thread_Times.
635 (start_timer_thread): Don't assign itimer->caller_thread here.

642 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
643 mouse movement events if the menu bar is active. This avoids
644 producing a busy "hour-glass" cursor by Windows if the mouse
645 pointer is positioned over a tooltip shown for some menu item.
647 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
649 Don't assume process IDs fit in int.
650 * emacs.c (shut_down_emacs) [!DOS_NT]:
651 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
652 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
653 Use pid_t, not int, to store process IDs, as 'int'
654 is not wide enough on a few platforms (e.g., AIX and IRIX).
656 2012-10-23 Kenichi Handa <handa@gnu.org>
658 The following change is to make face-font-rescale-alist work

681 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
684 * frame.c (Fmouse_position, Fmouse_pixel_position):
685 * xdisp.c (produce_stretch_glyph):
686 Declare local vars only when they're needed.
687 This is clearer and avoids a warning on OpenBSD about unused vars.
688 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
689 This is safer, and avoids OpenBSD warnings about unused vars.
690 * keyboard.c (record_menu_key): Remove unnecessary decl.
691 (poll_timer): Define only if POLL_FOR_INPUT is defined.
692 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
693 as our definition clashes with OpenBSD's.
694 * xfaces.c (load_face_colors, check_lface_attrs)
695 (get_lface_attributes_no_remap, get_lface_attributes)
696 (lface_fully_specified_p, x_supports_face_attributes_p)
697 (tty_supports_face_attributes_p, face_fontset, realize_face)
698 (realize_x_face, realize_tty_face):
699 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
700 merely Lisp_Object *. This is more informative and avoids
701 a warning on OpenBSD about accessing beyond an object's size.
703 2012-10-20 Chong Yidong <cyd@gnu.org>
705 * lread.c (Fload): Doc fix (Bug#12592).

731 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
732 (staticpro): If we run out of staticpro slots, die with an

989 (detect_input_pending_run_timers):
990 * process.c (wait_reading_process_output):
991 Use unsigned for counter where wraparound-on-overflow is desired,
992 since unsigned is guaranteed to have that behavior and signed is not.
993 (read_char): Use ptrdiff_t for string length.
994 (get_input_pending): Remove first argument, since it was always
995 the same pointer-to-int (now pointer-to-boolean) &input_pending,
996 and behave as if it had that value. Return new value of
997 input_pending. All callers changed.
998 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
999 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
1001 * keymap.c (push_key_description): Omit last arg, which was always 1.
1002 All callers changed.
1004 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.

1015 initializer for PVEC_NORMAL_VECTOR.
1017 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
1019 Clean out old termopts cruft.
1020 * termopts.h (flow_control, meta_key): Remove unused decls.
1021 * dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c:
1022 Don't include termopts.h.
1024 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
1026 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
1028 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
1030 * commands.h (immediate_quit): Remove duplicate decl.
1032 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
1034 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles

1037 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
1039 2012-10-09 Eli Zaretskii <eliz@gnu.org>
1041 * w32fns.c (w32_last_error): Change the return value to DWORD, to
1042 match what GetLastError returns. Explain why the function is
1045 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
1046 'is_tooltip_frame', to avoid confusion with its global namesake.
1048 2012-10-08 Daniel Colascione <dancol@dancol.org>
1050 * xdisp.c (start_hourglass): Call w32_note_current_window when
1051 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
1052 build that caused Emacs to display the hourglass cursor forever.
1054 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
1055 which is broken under remote desktop, calculate the number of
1056 colors available for a display based on the display's number of
1057 planes and number of bits per pixel per plane. (bug#10397).
1059 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
1061 * nsfont.m (Vfonts_in_cache): New variable.
1062 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
1063 are used. Add cached fonts to Vfonts_in_cache.
1064 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
1066 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
1068 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
1070 (FONT_H): Define after FRAME_H.
1071 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
1072 Update dependencies.
1074 * w32term.c: Remove leftover declaration of keyboard_codepage.
1076 2012-10-08 Eli Zaretskii <eliz@gnu.org>
1078 * makefile.w32-in (FONT_H): Add $(FRAME_H).
1079 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
1080 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.

1090 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
1092 (x_to_w32_color): Don't modify the argument, modify a copy instead.
1094 2012-10-08 Daniel Colascione <dancol@dancol.org>
1096 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
1097 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
1098 accidental message numbering hole. Change other messages to
1101 * w32select.h (HAVE_W32SELECT): Remove.
1103 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
1104 w32common.h instead of w32heap.h.

1115 (w32_minor_version, w32_build_number, w32_subtype):
1116 Remove duplicate definitions.
1118 * w32fns.c: Include w32common.h; include w32heap.h only in
1121 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
1122 Use `report_file_error' instead of `error' in order to better
1123 inform users of what went wrong. Increase NTGUI_UNICODE file
1124 dialog box file name length to 32k, the maximum allowed by the NT
1127 * w32common.h: New file.
1128 (ROUND_UP, ROUND_DOWN, get_page_size)
1129 (get_allocation_unit, get_processor_type, get_w32_major_version)
1130 (get_w32_minor_version, sysinfo_cache, osinfo_cache)

1132 (OS_NT, os_subtype, cache_system_info): Move here.
1134 * unexw32.c, unexcw.c: Include w32common.h.
1136 * emacs.c (main): Use (defined (WINDOWSNT) || defined
1137 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
1138 to call syms_of_w32select.
1140 * cygw32.h: Remove obsolete EXFUN declarations.
1142 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
1144 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
1145 of w32inevt.o from SOME_MACHINE_OBJECTS.
1147 2012-10-08 Daniel Colascione <dancol@dancol.org>
1149 * image.c: Permanent fix for JPEG compilation issue --- limit
1150 jpeglib `boolean' redefinition to Cygwin builds.
1152 2012-10-08 Eli Zaretskii <eliz@gnu.org>
1154 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
1156 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
1159 2012-10-08 Daniel Colascione <dancol@dancol.org>
1161 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
1162 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,

1166 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
1167 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
1168 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
1169 now a supported configuration.
1171 * Makefile.in: consolidate image variables into LIBIMAGE; add
1172 W32_OBJ and W32_LIBS. Compile new files.
1175 (_DebPrint) declare tracing facility for W32 debugging. We need
1176 to unify tracing later.
1178 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
1179 unconditional use of W32 Unicode functions. Cygwin runs only on
1180 100% Unicode operating systems.
1182 * cygw32.c: New file. Define Cygwin-specific facilities.
1183 (Fcygwin_convert_path_to_windows)
1184 (Fcygwin_convert_path_from_windows): New user functions for
1185 accessing Cygwin path-munging routines.
1187 * cygw32.h: New file.
1188 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
1189 UTF-16LE strings temporarily inside non-Lisp-visible string
1192 (w32_strerror): Just what it says on the tin.
1194 * emacs.c: Make the NS fork-then-exec code for daemon-launching
1195 also run for Cygwin; both systems have the same problem with using
1196 GUI facilities in a forked child. Also call syms_of_cygw32,
1197 syms_of_w32select in correct places.
1199 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
1200 needs fork-then-exec for daemon launching.
1202 * font.h: Include frame.h.
1204 * image.c: Use the image library cache machinery only when we're
1205 compiling for native WINDOWSNT; Cygwin can use shared libraries
1206 like any other Unixlike system.
1208 * keyboard.c: Clarify a comment regarding the input loop.
1210 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
1211 functions directly instead of trying to detect at runtime that our
1212 host operating system supports them. We make this change for two
1213 reasons: Cygwin lacks support for the multibyte character
1214 conversion functions used by the legacy menu code, and Cygwin
1215 never needs to rely on non-Unicode APIs.
1217 * unexw32.c (hinst): Declare extern.
1219 * w32.c: Change header order;
1220 (w32_strerror): Move to w32fns.c because we need it for
1221 non-WINDOWSNT builds.
1223 * w32.h: Add #error macro to make sure we don't include w32.h for
1224 Cygwin builds. Remove w32select declarations.
1226 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
1227 w32fns.c. w32console.c is WINDOWSNT-only.
1229 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
1230 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
1232 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
1233 (w32_major_version, w32_minor_version, w32_build_number)
1234 (os_subtype, sound_type): Define here
1235 (w32_defined_color): Make color parameter const for consistency
1236 with other _defined_color functions.
1237 (w32_createwindow): Unconditionally call w32_init_class instead of
1238 doing so only when hprevinst is non-NULL. Plumbing hprevinst
1239 through the code is complex and unnecessary because class
1240 registration is practically free.
1241 (w32_name_of_message): New EMACSDEBUG-only function.
1242 (Fset_message_beep): Move here
1243 (Fx_open_connection): Require that the display name for Windows be
1244 "w32" for consistency, emacsclient disambiguation, and maybe, one
1245 day, multi-window-system support.
1246 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
1247 Cygwin files for W32 GUI facilities, since these clearly don't
1248 expect Cygwin names.
1249 (_DebPrint): Define.
1250 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
1251 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
1252 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
1253 (w32_last_error): Remove.
1255 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
1257 * w32heap.c (syspage_mask): Declare here.
1258 (cache_system_info): Remove.
1260 * w32inevt.c (faked_key): Define globally, not statically.
1261 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
1262 (w32_console_toggle_lock_key): Move to w32fns.c.
1264 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
1266 * w32proc.c (_DebPrint): Move to w32fns.c.
1267 * w32select.c: Include string.h, stdio.h for Cygwin.
1268 * w32select.h: New File.
1270 * w32term.c: Include io.h for non-CYGWIN builds; needed for
1272 (w32_message_fd): New variable. Under Cygwin, holds the file
1273 descriptor the system used to tell us about pending thread
1276 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
1277 that prevented compilation under non-WINDOWSNT systems.
1279 (w32_initialize): Open /dev/windows and assign it to
1280 w32_message_fd. Provide w32 feature.
1282 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
1283 (WM_EMACS_INPUT_READY): add.
1284 (prepend_msg, w32_message_fd): Declare globally.
1287 (keyboard_handle): Use only when WINDOWSNT.
1288 (notify_msg_ready): New function. Posts a message to the main
1289 thread's message queue under CYGWIN, which wakes up the main
1290 thread from select(2) by making the /dev/windows file descriptor
1291 ready. Under WINDOWSNT, it sets an event the same way the old
1294 (post, prepend_msg): Actually call notify_msg_ready instead of
1295 setting the input event directly.
1297 2012-10-07 Eli Zaretskii <eliz@gnu.org>
1299 * ralloc.c (relinquish): If a heap is ready to be relinquished,
1300 but it still has blocs in it, don't return it to the system,
1301 instead of aborting. (Bug#12402)
1303 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
1305 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
1307 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
1308 MAC_OS_X_VERSION_10_6.
1309 (syms_of_nsterm): Remove comment about Panther and above for

1312 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
1313 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
1315 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
1316 MAC_OS_X_VERSION_10_4.
1318 * nsmenu.m (fillWithWidgetValue:): Remove code for <
1319 MAC_OS_X_VERSION_10_2.
1321 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
1323 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
1324 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
1326 * nsterm.m (ns_in_resize): Remove (Bug#12479).
1327 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
1328 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
1329 Remove ns_in_resize check.
1330 (ns_clear_frame_area): Remove resize handle code.
1332 * nsfns.m (ns_in_resize): Remove.
1333 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
1334 Remove ns_in_resize check.
1336 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
1338 Improve sys_siglist detection.
1339 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
1340 defined as a macro, as is done in Solaris.
1341 (sys_siglist_entries): New macro.
1342 (save_strsignal): Use it.
1343 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
1344 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
1346 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
1348 * nsfns.m (Fx_create_frame): Call x_default_parameter with
1349 fullscreen/Fullscreen.
1351 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
1352 tobar_height is new.
1354 * nsterm.m (x_make_frame_visible): Check for fullscreen.
1355 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
1356 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
1357 (windowDidResize:): Check for correct window if old style fullscreen.
1358 Capitalize word in comment. Remove incorrect comment.
1359 (initFrameFromEmacs:): tbar_height renamed tibar_height.
1360 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
1361 error in drawing background.
1362 (toggleFullScreen:): Remove comment. Rearrange calls.
1363 Set toolbar values to zero, save old height in tobar_height.
1364 Restore tool bar height when leaving fullscreen.
1365 (canBecomeMainWindow): New function.
1367 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
1369 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
1371 2012-10-05 Eli Zaretskii <eliz@gnu.org>
1373 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
1375 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
1376 that time stamps of directories could also be changed.
1377 Don't request the too broad GENERIC_WRITE, only the more restrictive
1378 FILE_WRITE_ATTRIBUTES access rights.
1380 * fileio.c (Fset_file_times): Special-case ignoring errors for
1381 directories only on MSDOS, not on MS-Windows.
1383 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
1385 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
1387 2012-10-04 Eli Zaretskii <eliz@gnu.org>
1389 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
1390 see whether CreateFile failed.
1392 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
1394 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
1395 to avoid similar races.
1396 * keyboard.c (pending_signals): Now bool, not int.
1398 Port timers to OpenBSD, plus check for timer failures.
1399 OpenBSD problem reported by Han Boetes.
1400 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
1402 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
1403 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
1404 like OpenBSD, which has timer_settime but does not declare it.
1405 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
1406 whether to use itimerspec-related primitives. All uses of
1407 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
1409 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
1411 * profiler.c (handle_profiler_signal): Fix a malloc race
1412 that caused Emacs to hang on Fedora 17 when profiling Lisp.

1420 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
1421 consistent with the change in return value of 'safe_strsignal'.
1423 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
1425 Prefer plain 'static' to 'static inline' (Bug#12541).
1426 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
1427 (bidi_set_sor_type, bidi_push_embedding_level)
1428 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

1437 Count overruns when profiling; change units to ns.
1438 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
1439 Give extra weight to samples after overruns, to attempt to count
1440 the time more accurately.
1441 (setup_cpu_timer): Change sampling interval units from ms to ns, since
1442 the underlying primitives nominally do ns.
1443 (Fprofiler_cpu_start): Document the change. Mention that
1444 the sampling intervals are only approximate.

1460 Update dependencies.
1462 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
1464 Fix a malloc race condition involving strsignal.
1465 A signal can arrive in the middle of a malloc, and Emacs's signal
1466 handler can invoke strsignal, which can invoke malloc, which is
1467 not portable. This race condition bug makes Emacs hang on GNU/Linux.
1468 Fix it by altering the signal handler so that it does not invoke
1470 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
1471 * process.c (status_message): Use const pointer, in case strsignal
1472 is #defined to safe_strsignal.
1473 * sysdep.c (sys_siglist, init_signals): Always define and
1474 initialize a substitute sys_siglist if the system does not define
1475 one, even if HAVE_STRSIGNAL.
1476 (safe_strsignal): Rename from strsignal. Always define,
1477 using sys_siglist. Return a const pointer.
1478 * syssignal.h (safe_strsignal): New decl.
1479 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
1481 2012-10-01 Eli Zaretskii <eliz@gnu.org>
1483 * w32proc.c (timer_loop): Fix code that waits for timer
1484 expiration, to avoid high CPU usage.

1488 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
1489 (sweep_weak_table): Remove redundant prototypes.
1491 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
1493 * emacs.c: Move the inclusion of TERM_HEADER after including
1494 windows.h on WINDOWSNT. This avoids compilation problems with
1497 2012-10-01 Eli Zaretskii <eliz@gnu.org>
1499 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
1500 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
1501 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
1502 as the previous version used 'void *'.
1504 * ralloc.c (ROUNDUP): Fix last change.
1505 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
1508 * w32proc.c <disable_itimers>: New static flag.
1509 (init_timers): Initialize it to zero, after creating the critical
1510 sections used by the timer threads.
1511 (term_timers): Set to 1 before deleting the critical sections.
1512 (getitimer, setitimer): If disable_itimers is non-zero, return an
1513 error indication without doing anything. Reported by Fabrice
1514 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
1515 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
1517 [!HAVE_SETITIMER]: Behave as the previous version that didn't
1520 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
1521 term_ntproc after all the other bookkeeping, to get timers working
1522 as long as possible.
1524 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
1526 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
1527 Suggested by Juri Linkov in
1528 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
1530 Prefer plain 'static' to 'static inline' (Bug#12541).
1531 With static functions, modern compilers inline pretty well by
1532 themselves; advice from programmers often hurts as much as it helps.
1533 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
1534 this change shrinks the text size of the Emacs executable by 1.1%
1535 without affecting CPU significantly in my benchmark.

1616 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
1618 Revert the FOLLOW-SYMLINKS change for file-attributes.
1619 Doing it right would require several changes to Tramp, and there's
1620 not enough time to get that tested before the freeze today.
1621 * dired.c (directory_files_internal, Ffile_attributes):
1624 * frame.c (x_report_frame_params): Port better to wider ints.
1625 Do not assume that EMACS_UINT is the same width as uprintmax_t,

1658 * w32.c (init_environment, get_emacs_configuration): Support AMD64
1660 (init_ntproc): Cast arguments of _open_osfhandle to intptr_t, for
1661 compatibility with x64.
1663 * vm-limit.c (lim_data): Now size_t.
1664 (check_memory_limits): Adjust prototypes of real_morecore and
1665 __morecore to receive argument of type ptrdiff_t. Use size_t for
1666 five_percent and data_size.
1668 * unexw32.c: Use DWORD_PTR instead of DWORD for file-scope
1669 variables, for compatibility with x64.

1691 * frame.c (x_report_frame_params): Use EMACS_UINT for the return
1692 value of FRAME_X_WINDOW, to fit a 64-bit pointer on 64-bit Windows
1695 * image.c (x_bitmap_pixmap): Return ptrdiff_t, not int, since

1719 sigfillset, and sigprocmask are no longer no-ops.
1720 (sigismember): New function.
1721 (struct itimer_data): New definition.
1722 (ticks_now, real_itimer, prof_itimer, clocks_min, crit_real)

1751 2012-09-30 Kenichi Handa <handa@gnu.org>
1753 * coding.c (decode_coding_ccl, encode_coding_ccl): Pay attention
1754 to the buffer relocation which may be caused by ccl_driver.

1811 2012-09-30 Eli Zaretskii <eliz@gnu.org>
1813 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
1814 HAVE_TIMER_SETTIME is defined.
1816 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
1818 Profiler improvements: more-accurate timers, overflow checks.
1819 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
1820 signal.h, setjmp.h. Include systime.h instead.
1821 (saturated_add): New function.
1822 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.

1828 All uses changed to store the new value.
1829 (handle_profiler_signal): Rename from sigprof_handler_1,
1830 for consistency with other handlers. Do not check whether
1831 cpu_log is a hash-table if garbage collecting, since it
1832 doesn't matter in that case.
1833 (deliver_profiler_signal): Rename from sigprof_handler,
1834 for consistency with other handlers.
1835 (setup_cpu_timer): New function, with much of what used to be in
1836 Fprofiler_cpu_start. Check for out-of-range argument.
1837 Prefer timer_settime if available, and prefer
1838 thread cputime clocks, then process cputime clocks, then
1839 monotonic clocks, to the old realtime clock. Use make_timeval
1840 to round more-correctly when falling back to setitimer.
1841 (Fprofiler_cpu_start): Use it.
1842 (Fprofiler_cpu_stop): Prefer timer_settime if available.
1843 Don't assume that passing NULL as the 2nd argument of setitimer
1844 is the same as passing a pointer to all-zero storage.
1845 Ignore SIGPROF afterwards.
1846 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
1847 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
1848 non-fatal signal handlers. Ignore SIGPROF on startup.
1849 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
1850 in profiler.c, since sysdep.c now uses it.
1852 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

1907 * charset.c, charset.h (maybe_unify_char): Now static.
1908 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
1909 Since this stuff is now private to charset.c, there's no need for
1910 a public macro and no need to inline by hand.
1912 2012-09-26 Tomohiro Matsuyama <tomo@cx4a.org>
1913 Stefan Monnier <monnier@iro.umontreal.ca>
1914 Juanma Barranquero <lekktu@gmail.com>

1939 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
1941 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
1943 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
1945 Prefer POSIX timers if available.
1946 They avoid a race if the timer is too close to the current time.
1947 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
1948 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.

1965 * image.c (reset_image_types): New function.
1967 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.

1974 * w32.h (Vlibrary_cache): Do not declare.
1976 2012-09-25 Eli Zaretskii <eliz@gnu.org>
1978 * w32proc.c (sys_signal): Handle all signals defined by the
1979 MS-Windows runtime, not just SIGCHLD. Actually install the signal
1980 handlers for signals supported by Windows. Don't override
1981 term_ntproc as the handler for SIGABRT.
1982 (sigaction): Rewrite to call sys_signal instead of duplicating its
1984 (sys_kill): Improve commentary.
1986 * w32.c (term_ntproc): Accept (and ignore) one argument, for
1987 consistency with a signature of a signal handler. All callers
1989 (init_ntproc): Accept an argument DUMPING. If dumping, don't
1990 install term_ntproc as a signal handler for SIGABRT, as that
1991 should be done by the dumped Emacs.
1993 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
1995 * w32select.c (term_w32select): Protect against repeated
1996 invocation by setting clipboard_owner to NULL after calling

2011 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
2013 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
2014 when encountering an unknown bytecode.
2016 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
2018 image.c, indent.c: Use bool for booleans.
2019 * dispextern.h (struct image_type): Members valid_p, load, init
2020 now return bool, not int. All uses changed.
2021 * image.c: Omit unnecessary static decls.
2022 (x_create_bitmap_mask, x_build_heuristic_mask):
2023 Return void, not int, since callers don't care about the return value.

2054 2012-09-24 Chong Yidong <cyd@gnu.org>
2056 * chartab.c (Fset_char_table_default): Obsolete function removed.
2058 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
2060 Move pid_t related decls out of lisp.h.
2061 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
2062 (interruptible_wait_for_termination):
2063 Move these decls from lisp.h to syswait.h, since they use pid_t.
2064 Needed on FreeBSD; see Herbert J. Skuhra in
2065 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
2066 * callproc.c: Include syswait.h.

2084 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):

2086 Use bool for boolean.
2087 * gtkutil.c (xg_update_frame_menubar):
2088 * xmenu.c (update_frame_menubar):
2089 Return void, not int, since caller ignores return value.

2093 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
2095 * makefile.w32-in (BLOCKINPUT_H): Remove.

2112 2012-09-23 Eli Zaretskii <eliz@gnu.org>
2114 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
2115 fatal_error_backtrace.
2117 * w32proc.c (sys_kill): Undo last change: don't do anything when
2118 invoked to deliver SIGABRT to our own process. This is now
2119 handled by emacs_raise.
2121 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
2123 * w32term.c (w32_read_socket): Remove leftover reference to
2124 interrupt_input_pending.
2126 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
2128 Do not use SA_NODEFER.
2129 Problem reported by Dani Moncayo in
2130 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
2132 * sysdep.c (emacs_abort): Do not reset signal handler.
2133 * emacs.c (terminate_due_to_signal): Reset signal handler here.
2134 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
2135 wanted even on POSIXish hosts, and it doesn't work on Windows.
2137 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
2139 * xterm.c (x_term_init): Call fixup_locale before and after calling
2140 gtk_init (Bug#12392).
2142 2012-09-23 Chong Yidong <cyd@gnu.org>
2144 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
2145 Vdynamic_library_alist.
2147 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
2148 (Fgnutls_available_p): Caller changed.
2150 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
2151 (Flibxml_parse_xml_region): Likewise.
2153 * dispextern.h (struct image_type): Remove arg from init function.
2155 * image.c (Finit_image_library, lookup_image_type)
2156 (define_image_type): Remove now-unneeded second arg.
2157 (init_xpm_functions, init_png_functions, init_jpeg_functions)
2158 (init_tiff_functions, init_gif_functions, init_svg_functions):
2159 Arglist and w32_delayed_load calling convention changed.
2160 (gs_type): Remove init_gs_functions; there is no such function.
2161 (valid_image_p, make_image): Fix caller to lookup_image_type.
2163 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
2165 Simplify and avoid signal-handling races (Bug#12471).
2167 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
2168 Avoid recursive loop if there's a fatal error in the function itself.
2169 * atimer.c (pending_atimers):
2170 * blockinput.h: Don't include "atimer.h"; no longer needed.
2171 (interrupt_input_pending): Remove. All uses removed.
2172 pending_signals now counts both atimers and ordinary interrupts.
2173 This is less racy than having three separate pending-signal flags.
2174 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
2176 Rename from their upper-case counterparts BLOCK_INPUT,
2177 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
2178 INPUT_BLOCKED_P, and turn into functions. All uses changed.
2179 This makes it easier to access volatile variables more accurately.
2180 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
2181 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
2182 that's more reliable if the code is buggy and sets
2183 interrupt_input_blocked to a negative value. All uses changed.
2184 * atimer.c (deliver_alarm_signal):
2185 Remove. No need to deliver this to the parent; any thread can
2186 handle this signal now. All uses replaced by underlying handler.
2187 * atimer.c (turn_on_atimers):
2188 * dispnew.c (handle_window_change_signal):
2189 * emacs.c (handle_danger_signal):
2190 * keyboard.c (kbd_buffer_get_event):
2191 Don't reestablish signal handler; not needed with sigaction.
2192 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
2194 Rework to avoid unnecessary accesses to volatile variables.
2195 (UNBLOCK_INPUT_TO): Now a function.
2196 (totally_unblock_input, unblock_input): New decls.
2197 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
2198 (init_data): Remove. Necessary stuff now done in init_signal.
2199 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
2200 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
2201 (fatal_error_code): Remove; no longer needed.
2202 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
2203 it doesn't always backtrace. All uses changed. No need to reset
2204 signal to default, since sigaction and/or die does that for us now.
2205 Use emacs_raise (FOO), not kill (getpid (), FOO).
2206 (main): Check more-accurately whether we're dumping.
2207 Move fatal-error setup to sysdep.c
2208 * floatfns.c: Do not include "syssignal.h"; no longer needed.
2209 * gtkutil.c (xg_get_file_name, xg_get_font):
2210 Remove no-longer-needed signal-mask manipulation.
2211 * keyboard.c, process.c (POLL_FOR_INPUT):
2212 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
2213 * keyboard.c (read_avail_input): Remove.
2214 All uses replaced by gobble_input.
2215 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
2216 (kbd_buffer_store_event_hold, gobble_input):
2217 (record_asynch_buffer_change) [USABLE_SIGIO]:
2218 (store_user_signal_events):
2219 No need to mess with signal mask.
2220 (gobble_input): If blocking input and there are terminals, simply
2221 set pending_signals to 1 and return. All hooks changed to not
2222 worry about whether input is blocked.
2223 (process_pending_signals): Clear pending_signals before processing
2224 them, in case a signal comes in while we're processing.
2225 By convention callers now test pending_signals before calling us.
2226 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
2227 New functions, to support changes to blockinput.h.
2228 (handle_input_available_signal): Now extern.
2229 (reinvoke_input_signal): Remove. All uses replaced by
2231 (quit_count): Now volatile, since a signal handler uses it.
2232 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
2233 All callers changed. Block SIGINT only if not already blocked.
2234 Clear sigmask reliably, even if Fsignal returns, which it can.
2235 Omit unnecessary accesses to volatile var.
2236 (quit_throw_to_read_char): No need to restore sigmask.
2237 * keyboard.c (gobble_input, handle_user_signal):
2238 * process.c (wait_reading_process_output):
2239 Call signal-handling code rather than killing ourselves.
2240 * lisp.h: Include <float.h>, for...
2241 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
2242 (pending_signals): Now volatile.
2243 (syms_of_data): Now const if IEEE floating point.
2244 (handle_input_available_signal) [USABLE_SIGIO]:
2245 (terminate_due_to_signal, record_child_status_change): New decls.
2246 * process.c (create_process): Avoid disaster if memory is exhausted
2247 while we're processing a vfork, by tightening the critical section
2249 (send_process_frame, process_sent_to, handle_pipe_signal)
2250 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
2252 (send_process): No need for setjmp/longjmp any more, since the
2253 SIGPIPE stuff is now gone. Instead, report an error if errno
2255 (record_child_status_change): Now extern. PID and W are now args.
2256 Return void, not bool. All callers changed.
2257 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
2258 Remove. All uses removed. This bug should be fixed now in a
2260 (wait_for_termination_1): Use waitpid rather than sigsuspend,
2261 and record the child status change directly. This avoids the
2262 need to futz with the signal mask.
2263 (process_fatal_action): Move here from emacs.c.
2264 (emacs_sigaction_flags): New function, containing
2265 much of what used to be in emacs_sigaction_init.
2266 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
2267 caught by emacs, to make races less likely.
2268 (deliver_process_signal): Rename from handle_on_main_thread.
2270 (BACKTRACE_LIMIT_MAX): Now at top level.
2271 (thread_backtrace_buffer, threadback_backtrace_pointers):
2273 (deliver_thread_signal, deliver_fatal_thread_signal):
2274 New functions, for more-accurate delivery of thread-specific signals.
2275 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
2276 (deliver_arith_signal): Handle in this thread, not
2277 in the main thread, since it's triggered by this thread.
2278 (maybe_fatal_sig): New function.
2279 (init_signals): New arg DUMPING so that we can be more accurate
2280 about whether we're dumping. Caller changed.
2281 Treat thread-specific signals differently from process-general signals.
2282 Block all signals while handling fatal error; that's safer.
2283 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
2285 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
2286 Ignore SIGPIPE unless batch.
2287 (emacs_backtrace): Output backtrace for the appropriate thread,
2288 which is not necessarily the main thread.
2289 * syssignal.h: Include <stdbool.h>.
2290 (emacs_raise): New macro.
2291 * xterm.c (x_connection_signal): Remove; no longer needed
2292 now that we use sigaction.
2293 (x_connection_closed): No need to mess with sigmask now.
2294 (x_initialize): No need to reset SIGPIPE handler here, since
2295 init_signals does this for us now.
2297 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
2299 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
2300 background rect may be larger (Bug#12245).
2302 2012-09-23 Chong Yidong <cyd@gnu.org>
2304 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
2306 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
2308 * .gdbinit: Just stop at fatal_error_backtrace.
2309 See Stefan Monnier's request in
2310 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
2311 Remove no-longer-used query of system type.
2313 2012-09-22 Chong Yidong <cyd@gnu.org>
2315 * search.c (Freplace_match): Doc fix (Bug#12325).
2317 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
2319 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
2320 (Fline_end_position): Doc fix.
2322 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
2324 2012-09-22 Chong Yidong <cyd@gnu.org>
2326 * dispextern.h (struct image_type): Add new slot, storing a type
2327 initialization function.
2329 * image.c (define_image_type): Call the image initializer function
2330 if it is defined. Arguments and return value changed.
2331 (valid_image_p, make_image): Callers changed.
2332 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
2333 (gif_type, imagemagick_type, svg_type, gs_type):
2334 Add initialization functions.
2335 (Finit_image_library): Call lookup_image_type.
2336 (CHECK_LIB_AVAILABLE): Macro deleted.
2337 (lookup_image_type): Call define_image_type here, rather than via
2338 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
2339 (syms_of_image): Move define_image_type calls for xbm_type and
2340 pbm_type to lookup_image_type.
2342 2012-09-22 Eli Zaretskii <eliz@gnu.org>
2344 * keyboard.c (timer_check_2): Move calculation of 'timers' and
2345 'idle_timers' from here ...
2346 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
2347 lists, to avoid infloops when the timer does something stupid,
2348 like reinvoke itself with the same or smaller time-out.
2351 2012-09-22 Martin Rudalics <rudalics@gmx.at>
2353 * window.c (Fsplit_window_internal): Handle only Qt value of
2354 Vwindow_combination_limit separately.
2355 (Qtemp_buffer_resize): New symbol.
2356 (Vwindow_combination_limit): New default value.
2359 2012-09-22 Eli Zaretskii <eliz@gnu.org>
2361 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
2362 the new overlay string. (Bug#10159)
2364 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
2366 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
2367 or that fprintf is async-signal-safe. POSIX doesn't require
2370 2012-09-22 Chong Yidong <cyd@gnu.org>
2372 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
2375 2012-09-22 Kenichi Handa <handa@gnu.org>
2377 * composite.c (composition_reseat_it): Handle the case that a
2378 grapheme cluster is not covered by a single font (Bug#12352).
2380 2012-09-21 Chong Yidong <cyd@gnu.org>
2382 * image.c (define_image_type): Avoid adding duplicate types to
2383 image_types (Bug#12463). Suggested by Jörg Walter.
2385 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2387 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
2388 (print_load_command_name): Add case LC_DATA_IN_CODE.
2389 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
2391 2012-09-21 Glenn Morris <rgm@gnu.org>
2393 * eval.c (Frun_hook_with_args_until_success)
2394 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
2396 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
2398 * fileio.c (Ffile_selinux_context): Only call freecon when
2399 lgetfilecon succeeded.
2400 (Fset_file_selinux_context): Likewise. (Bug#12444)
2402 2012-09-21 Eli Zaretskii <eliz@gnu.org>
2404 * xdisp.c (try_window_reusing_current_matrix): Under bidi
2405 reordering, locate the cursor by calling set_cursor_from_row; if
2406 that fails, clear the desired glyph matrix before returning a
2407 failure indication to the caller. Fixes leaving garbled display
2408 when fast scrolling with a down-key. (Bug#12403)
2409 (compute_stop_pos_backwards): Fix a typo that caused crashes while
2410 scrolling through multibyte text.
2412 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
2414 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
2415 calling mark_vectorlike since that's the one that marks the window.
2416 (mark_discard_killed_buffers): Mark the final cdr.
2417 * window.h (struct window): Move prev/next_buffers to the
2418 non-standard fields.
2419 * window.c (make_window): Initialize prev/next_buffers manually.
2421 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
2423 Omit unused arg EXPECTED from socket hooks.
2424 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
2425 * nsterm.m (ns_term_init):
2426 * termhooks.h (struct terminal.read_socket_hook):
2427 * w32inevt.c (w32_console_read_socket):
2428 * w32term.c (w32_read_socket):
2429 * xterm.c (XTread_socket):
2430 Omit unused arg EXPECTED. All callers changed.
2431 (store_user_signal_events): Return void, not int, since callers no
2432 longer care about the return value. All uses changed.
2434 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
2436 * w32gui.h (XParseGeometry): Do not declare.
2438 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
2440 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
2441 Ignore 'expected'. See Eli Zaretskii in
2442 <http://bugs.gnu.org/12471#8> (last line).
2444 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
2445 (XParseGeometry): Now static. Substitute extremal values for
2446 values that are out of range.
2448 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
2450 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
2452 * nsfns.m (XParseGeometry): Remove.
2453 (Fx_create_frame): Call x_set_offset to correctly interpret
2454 top_pos in geometry.
2456 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
2457 (Fx_parse_geometry): If there is a space in string, call
2458 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
2460 2012-09-17 Eli Zaretskii <eliz@gnu.org>
2462 * search.c (scan_buffer): Use character positions in calls to
2463 region_cache_forward and region_cache_backward, not byte
2464 positions. (Bug#12196)
2466 * w32term.c (w32_read_socket): Set pending_signals to 1, like
2467 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
2469 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
2470 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
2471 emacs_blocked_malloc, now deleted.
2473 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
2475 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
2476 The workaround was for improving performance on Solaris 2.4, but
2477 is getting in the way now. Emacs will still work if someone is
2478 still running Solaris 2.4 in a museum somewhere; Sun dropped
2479 support for Solaris 2.4 in 2003.
2480 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
2481 * process.c (create_process) [HAVE_WORKING_VFORK]:
2482 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
2483 since Emacs no longer uses vfork on that platform.
2485 2012-09-17 Glenn Morris <rgm@gnu.org>
2487 * emacs.c: Use COPYRIGHT.
2489 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
2491 Remove configure's --without-sync-input option (Bug#12450).
2492 When auditing signal-handling in preparation for cleaning it up,
2493 I found that SYNC_INPUT has race conditions and would be a real
2494 pain to fix. Since it's an undocumented and deprecated
2495 configure-time option, now seems like a good time to remove it.
2496 Also see <http://bugs.gnu.org/11080#16>.
2497 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
2498 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
2499 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
2500 (malloc_hysteresis):
2501 (check_depth) [XMALLOC_OVERRUN_CHECK]:
2502 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
2503 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
2504 (dont_register_blocks, bytes_used_when_reconsidered)
2505 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
2506 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
2507 [!SYSTEM_MALLOC && !SYNC_INPUT]:
2508 Remove. All uses removed.
2509 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
2510 implementation, one that depends on whether the new macro
2511 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
2513 * atimer.c (run_timers, handle_alarm_signal):
2514 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
2515 (handle_async_input, process_pending_signals)
2516 (handle_input_available_signal, init_keyboard):
2517 * nsterm.m (ns_read_socket):
2518 * process.c (wait_reading_process_output):
2519 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
2520 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
2522 * xterm.c (XTread_socket):
2524 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
2525 * eval.c (handling_signal): Remove. All uses removed.
2526 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
2527 All uses replaced with the SYNC_INPUT version.
2528 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
2530 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2533 * font.c (Ffont_shape_gstring): Remove unused local.
2535 2012-09-16 Glenn Morris <rgm@gnu.org>
2537 * Makefile.in (clean): No longer run nextstep's clean.
2539 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
2541 (ns-app): Move here from ns.mk, and simplify.
2542 (clean): Simplify nextstep entry.
2543 * ns.mk: Remove file.
2545 2012-09-17 Kenichi Handa <handa@gnu.org>
2547 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
2548 not covert the last few charactes.
2550 2012-09-16 Kenichi Handa <handa@gnu.org>
2552 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
2553 here, but just check the validity of glyphs in the glyph-string.
2555 2012-09-16 Martin Rudalics <rudalics@gmx.at>
2557 * window.c (Fwindow_parameter, Fset_window_parameter):
2558 Accept any window as argument (Bug#12452).
2560 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
2562 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
2563 to ns_term_init to avoid memory leak.
2565 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
2566 explicit retain/release.
2567 (ns_term_init): Only allow one display. Initialize outerpool and
2570 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
2572 Port _setjmp fix to POSIXish hosts as well as Microsoft.
2573 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
2574 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
2575 the Microsoft problem in a different way, by altering ../nt/config.nt.
2577 2012-09-15 Eli Zaretskii <eliz@gnu.org>
2592 * w16select.c: Remove inclusion of setjmp.h, as it is now included
2593 by lisp.h. This completes removal of setjmp.h inclusion
2594 erroneously announced in the previous commit. (Bug#12446)
2596 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
2599 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
2600 not defined as a macro. The latter happens on MS-Windows.
2603 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
2605 Port better to POSIX hosts lacking _setjmp (Bug#12446).
2606 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
2607 Some instances of '#include <setjmp.h>' removed, if the
2608 only reason for the instance was because "lisp.h" was included.
2609 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
2610 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
2611 and _longjmp with the new symbols. Emacs already uses _setjmp if
2612 available, so this change affects only POSIXish hosts that have
2613 sigsetjmp but not _setjmp, such as some versions of Solaris and
2614 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
2615 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
2616 (png_load_body) [HAVE_PNG]:
2617 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
2618 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
2619 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
2620 since PNG requires jmp_buf. This is the only exception to the
2621 general rule that we now use sys_setjmp and sys_longjmp.
2622 This exception is OK since this code does not change the signal
2623 mask or longjmp out of a signal handler.
2625 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
2627 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
2628 Include "syssignal.h", for 'main_thread'.
2630 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
2632 Avoid out-of-range marker position (Bug#12426).
2633 * insdel.c (replace_range, replace_range_2):
2634 Adjust markers before overlays, as suggested by comments.
2635 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
2636 Remove redundant check before calling offset_intervals.
2638 2012-09-14 Martin Rudalics <rudalics@gmx.at>
2640 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
2641 current buffer (Bug#12387).
2643 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
2645 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
2647 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
2649 Use a more backwards-compatible timer format (Bug#12430).
2650 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
2651 vector element, not from the 4th, since PSECS is now at the end.
2652 (Fcurrent_idle_time): Doc fix.
2654 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
2656 Function to mark objects and remove killed buffers at once.
2657 * alloc.c (discard_killed_buffers): Rename to ...
2658 (mark_discard_killed buffers) ... new name. Add marking
2659 of remaining objects. Fix comment. Adjust users.
2660 (mark_object): Do not touch frame buffer lists here.
2661 * frame.c (delete_frame): Reset frame buffer lists here.
2663 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
2665 Better workaround for GNOME bug when --enable-gcc-warnings.
2666 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
2667 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
2668 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
2670 Simplify SIGIO usage (Bug#12408).
2671 The code that dealt with SIGIO was crufty and confusing, e.g., it
2672 played tricks like "#undef SIGIO" but these tricks were not used
2673 consistently. Simplify mostly by not #undeffing standard symbols,
2674 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
2675 or not as we please) rather than "defined SIGIO" (standard symbol
2676 that we probably shouldn't #undef).
2677 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
2678 Modules that need it can include it.
2679 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
2680 * dispextern.h (ignore_sigio): New decl.
2681 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
2682 unconditionally, since it's now a no-op if !USABLE_SIGIO.
2683 * emacs.c (shut_down_emacs):
2684 * keyboard.c (kbd_buffer_store_event_hold):
2685 Use ignore_sigio rather than invoking 'signal' directly.
2686 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
2688 (FIONREAD, SIGIO): Do not #undef.
2689 (tty_read_avail_input): Use #error rather than a syntax error.
2690 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
2691 for I_PIPE, used by SETUP_SLAVE_PTY.
2692 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
2693 * sysdep.c (croak): Remove; no longer needed. This bit of
2694 temporary code, with Fred N. Fish's comment that it's temporary,
2695 has been in Emacs since at least 1992!
2696 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
2697 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
2698 * syssignal.h (croak): Remove decl.
2699 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
2700 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
2701 now that we're termios-only.
2702 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
2703 * term.c (dissociate_if_controlling_tty): Use #error rather than
2706 Work around GCC and GNOME bugs when --enable-gcc-warnings.
2707 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
2708 to work around GNOME bug 683906.
2709 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
2710 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
2711 This works around GCC bug 54561.
2713 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
2715 More fixes for 'volatile' and setjmp/longjmp.
2716 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
2717 * image.c (struct png_load_context) [HAVE_PNG]: New type.
2718 (png_load_body) [HAVE_PNG]:
2719 (jpeg_load_body) [HAVE_JPEG]:
2720 New function, with most of the old parent function's body.
2721 (png_load) [HAVE_PNG]:
2722 (jpeg_load) [HAVE_JPEG]:
2723 Invoke the new function, to avoid longjmp munging our locals.
2724 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
2725 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
2726 longjmp is passed 2, as the C standard doesn't guarantee this.
2727 Instead, store the failure code into mgr->failure_code.
2729 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
2731 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
2732 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
2733 (syms_of_keyboard): Remove support for unread-command-char.
2735 2012-09-12 Eli Zaretskii <eliz@gnu.org>
2737 * w32proc.c (sys_kill): If PID is our process ID and the signal is
2738 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
2739 violation. (Bug#12426)
2741 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
2743 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
2745 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
2747 * eval.c: Add `inhibit-debugger'.
2748 (Qinhibit_debugger): New symbol.
2749 (call_debugger): Bind it instead of Qdebug_on_error.
2750 (maybe_call_debugger): Test Vinhibit_debugger.
2751 (syms_of_eval): Define inhibit-debugger.
2752 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
2753 (syms_of_xdisp): Remove inhibit-debug-on-message.
2755 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
2757 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
2758 If a nonvolatile local variable is written before a _longjmp to
2759 the frame containing the variable, and is read after the _longjmp,
2760 the value read is indeterminate. Some local variables of type
2761 'struct handler' and 'struct catchtag' are used in this way, so
2762 mark each of their slots as volatile if the slot can be set before
2763 _longjmp and read afterwards.
2764 * lisp.h (struct handler): var and chosen_clause are now volatile.
2765 (struct catchtag): val, next, and pdlcount are now volatile.
2767 * bidi.c (bidi_push_it, bidi_pop_it):
2768 * fns.c (copy_hash_table):
2769 * image.c (define_image_type):
2770 * keyboard.c (kbd_buffer_store_event_hold):
2771 * process.c (Fprocess_send_eof):
2772 * xfaces.c (x_create_gc) [HAVE_NS]:
2773 * xgselect.c (xg_select):
2774 Prefer assignment to memcpy when either will do.
2776 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
2777 Use pointer-to-a-pointer to simplify and avoid a NILP check each
2778 time an item is removed. No need to mark this function 'inline';
2779 the compiler knows better than we do.
2781 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
2783 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
2784 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
2785 to change_frame_size (Bug#12388).
2786 (windowDidResize:): Pass YES to updateFrameSize.
2788 * nsterm.h: Add delay parameter to updateFrameSize.
2790 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
2792 Discard killed buffers from deleted window and frame objects.
2793 This reduces an amount of references to killed buffers and
2794 helps GC to reclaim them faster.
2795 * alloc.c (discard_killed_buffers): New function.
2796 (mark_object): Use it for deleted windows and frames.
2797 (mark_object): If symbol's value is set up for a killed buffer
2798 or deleted frame, restore its global binding.
2799 * data.c (swap_in_global_binding): Add GC notice.
2800 (swap_in_symval_forwarding): Use convenient set_blv_where.
2801 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
2802 * window.h: ... to here.
2804 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
2806 Convenient macro to check whether the buffer is live.
2807 * buffer.h (BUFFER_LIVE_P): New macro.
2808 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
2809 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
2811 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2813 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
2814 composition cases (Bug#12364).
2816 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
2817 overhang of succeeding glyphs overlapping box cursor.
2819 * w32term.c (x_draw_glyph_string): Likewise.
2821 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
2823 Simplify, document, and port floating-point (Bug#12381).
2824 The porting part of this patch fixes bugs on non-IEEE platforms
2825 with frexp, ldexp, logb.
2826 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
2828 * floatfns.c: Simplify discussion of functions that Emacs doesn't
2829 support, by removing commented-out code and briefly listing the
2830 C89 functions excluded. The commented-out stuff was confusing
2831 maintenance, e.g., we thought we needed cbrt but it was commented out.
2832 (logb): Remove decl; no longer needed.
2833 (isfinite): New macro, if not already supplied.
2834 (isnan): Don't replace any existing macro.
2835 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
2836 are present on all C89 platforms.
2837 (Ffrexp): Do not special-case zero, as frexp does the right thing
2839 (Flogb): Do not use logb, as it doesn't have the desired meaning
2840 on hosts that use non-base-2 floating point. Instead, stick with
2841 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
2842 frexp, to avoid getting an unspecified result.
2844 * xdisp.c (Qinhibit_debug_on_message): Now static.
2846 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
2848 * nsterm.m (ns_update_begin): Set clip path to whole view by using
2849 NSBezierPath (Bug#12131).
2851 2012-09-10 Chong Yidong <cyd@gnu.org>
2853 * fns.c (Fdelq, Fdelete): Doc fix.
2855 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
2857 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
2858 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
2860 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
2862 * lisp.h (make_lisp_ptr): New macro to replace XSET.
2863 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
2866 2012-09-09 Eli Zaretskii <eliz@gnu.org>
2868 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
2869 left fringe if the window has a left margin. This avoids leaving
2870 traces of the cursor because its leftmost pixel is not drawn over.
2872 * dispnew.c (update_window_line): When the left margin area of a
2873 screen line is updated, set the redraw_fringe_bitmaps_p flag of
2874 that screen line. (Bug#12277)
2876 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
2878 Assume C89 or later for math functions (Bug#12381).
2879 This simplifies the code, and makes it a bit smaller and faster,
2880 and (most important) makes it easier to clean up signal handling
2881 since we can stop worring about floating-point exceptions in
2882 library code. That was a problem before C89, but the problem
2883 went away many years ago on all practical Emacs targets.
2884 * data.c, image.c, lread.c, print.c:
2885 Don't include <math.h>; no longer needed.
2886 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
2887 might be autoconfigured, as that never happens.
2889 * doprnt.c (DBL_MAX_10_EXP):
2890 * print.c (DBL_DIG):
2891 Remove. C89 or later always defines these.
2892 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
2893 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
2894 (arith_error, domain_error, domain_error2):
2895 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
2896 no longer needed -- we simply return what C returns. All uses removed.
2897 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
2899 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
2900 Remove. All uses expanded, as these macros are no longer used
2901 more than once and are now more trouble than they're worth.
2902 (Ftan): Use tan, not sin / cos.
2903 (Flogb): Assume C89 frexp.
2904 (fmod_float): Assume C89 fmod.
2905 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
2906 (init_floatfns): Remove. All uses removed.
2908 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2910 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
2911 compositeToPoint for OSX < 10.6 (Bug#12390).
2913 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
2915 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
2916 This produces more-accurate results.
2918 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2920 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
2921 changes (Bug#12088).
2923 2012-09-08 Chong Yidong <cyd@gnu.org>
2925 * syntax.c (Fstring_to_syntax): Doc fix.
2927 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2929 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
2930 in the internal border.
2931 (x_set_window_size): Remove static variables and their usage.
2932 (ns_redraw_scroll_bars): Fix NSTRACE arg.
2933 (ns_after_update_window_line, ns_draw_fringe_bitmap):
2934 Remove fringe/internal border adjustment (Bug#11052).
2935 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
2936 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
2937 (ns_fix_rect_ibw): Remove.
2938 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
2939 (ns_dumpglyphs_box_or_relief): Ditto.
2940 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
2942 (ns_dumpglyphs_image): Ditto.
2943 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
2945 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
2946 their usage. Add fringe_extended_p and its use as in other terms.
2947 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
2948 scroll bar was removed.
2949 (updateFrameSize): New function.
2950 (windowDidResize): Move code to updateFrameSize and call it.
2952 * nsterm.h (EmacsView): Add updateFrameSize.
2954 2012-09-07 Chong Yidong <cyd@gnu.org>
2956 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
2958 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
2960 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
2962 More signal-handler cleanup (Bug#12327).
2963 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
2964 Problem introduced when merging patches. Noted by Eli Zaretskii in
2965 <http://bugs.gnu.org/12327#67>.
2966 * floatfns.c: Comment fix.
2967 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
2968 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
2969 and anyway the declaration is harmless even if SIGDANGER is not defined.
2970 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
2971 defined BROKEN_FIONREAD). systty.h formerly did this, but other
2972 source files not surprisingly expected syssignal.h to define, or
2973 not define, SIGIO, and it's cleaner to do it that way, for consistency.
2974 Include <sys/ioctl.h>, for FIONREAD.
2975 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
2976 This eliminates a problem whereby other files mysteriously had
2977 to include "syssignal.h" before including "systty.h" if they
2978 wanted to use "#ifdef SIGIO".
2980 2012-09-07 Eli Zaretskii <eliz@gnu.org>
2982 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
2984 * w32.c (sigemptyset): Empty the set.
2985 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
2987 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
2989 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
2991 * alloc.c (mark_buffer): Revert unsafe marking optimization.
2992 (mark_object): Likewise for frame objects.
2994 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
2996 * syssignal.h (handle_on_main_thread): Always declare,
2997 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
2998 This ports to platforms without HAVE_PTHREAD.
3000 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
3002 Signal-handler cleanup (Bug#12327).
3003 Emacs's signal handlers were written in the old 4.2BSD style with
3004 sigblock and sigmask and so forth, and this led to some
3005 inefficiencies and confusion. Rewrite these to use
3006 pthread_sigmask etc. without copying signal sets around. Also,
3007 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
3008 'signal', and instead use functions that do not attempt to take
3009 over the system name space. This patch causes Emacs's text
3010 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
3011 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
3012 Do not include <signal.h> or "syssignal.h", as these
3013 modules do not use signals.
3014 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
3015 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
3016 Do not include <signal.h>, as "syssignal.h" does that for us now.
3017 * atimer.c (sigmask_atimers): New function.
3018 (block_atimers, unblock_atimers): New functions,
3019 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
3021 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
3022 no longer needed here.
3023 * emacs.c (main): Inspect existing signal handler with sigaction,
3024 so that there's no need to block and unblock SIGHUP.
3025 * sysdep.c (struct save_signal): New member 'action', replacing
3026 old member 'handler'.
3027 (save_signal_handlers, restore_signal_handlers):
3028 Use sigaction instead of 'signal' to save and restore.
3029 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
3030 New function. All users of 'signal' modified to use set_sighandler
3031 if they're writeonly, and to use sys_signal if they're read+write.
3032 (emacs_sigaction_init, forwarded_signal): New functions.
3033 (sys_signal): Remove. All uses replaced by calls to sigaction
3034 and emacs_sigaction_init, or by direct calls to 'signal'.
3035 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
3036 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
3037 all uses replaced by pthread_sigmask etc. calls.
3038 * syssignal.h: Include <signal.h>.
3039 (emacs_sigaction_init, forwarded_signal): New decls.
3040 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
3041 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
3042 (sigmask, sys_sigmask): Remove; no longer needed.
3043 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
3044 (sigblock, sigunblock, sigfree):
3045 (sigsetmask) [!defined sigsetmask]:
3046 Remove. All uses replaced by pthread_sigmask.
3047 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
3048 no longer need to be replaced, and its typical old uses
3049 are now done via emacs_sigaction_init and sigaction.
3050 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
3051 (sys_sigdel): Remove; unused.
3052 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
3054 2012-09-06 Eli Zaretskii <eliz@gnu.org>
3056 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
3057 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
3059 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
3061 Explicitly mark buffer_defaults and buffer_local_symbols.
3062 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
3063 mark_local_symbols here.
3064 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
3065 since special buffers aren't marked here any more.
3066 (allocate_buffer): Chain new buffer with all_buffers here...
3067 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
3069 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
3070 (syms_of_buffer): Remove staticpro of the above.
3071 (init_buffer_once): Set names for buffer_defaults and
3072 buffer_local_symbols.
3074 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
3076 Use bool for booleans in font-related modules.
3077 * font.c (font_intern_prop, font_style_to_value)
3078 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
3079 (generate_otf_features, font_check_otf_features, font_check_otf)
3080 (font_match_p, font_list_entities, font_at):
3081 * fontset.c (fontset_id_valid_p, reorder_font_vector
3082 (fontset_find_font, Fset_fontset_font)
3083 (face_suitable_for_char_p) [0]:
3084 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
3085 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
3086 (m17n_flt_initialized, ftfont_shape_by_flt):
3087 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
3088 * nsfont.m (nsfont_draw):
3089 * w32font.c (w32font_draw):
3090 * w32term.c (x_draw_glyphless_glyph_string_foreground):
3091 Use bool for booleans.
3092 * font.h: Adjust to above API changes.
3093 (struct font, struct font_driver, struct font_driver_list):
3094 Use bool for booleans.
3095 (struct font): Remove useless member encoding_type.
3097 * fontset.c, xftfont.c: Omit unnecessary static decls.
3099 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
3101 * alloc.c (mark_object): Revert window marking code
3102 since it's unsafe for the Fset_window_configuration.
3104 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
3106 Fix race conditions with signal handlers and errno (Bug#12327).
3107 Be more systematic about preserving errno whenever a signal
3108 handler returns, even if it's not in the main thread. Do this by
3109 renaming signal handlers to distinguish between signal delivery
3110 and signal handling. All uses changed.
3111 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
3112 * data.c (deliver_arith_signal): Rename from arith_error.
3113 * dispnew.c (deliver_window_change_signal): Rename from
3114 window_change_signal.
3115 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
3116 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
3117 * keyboard.c (deliver_input_available_signal): Rename from
3118 input_available_signal.
3119 (deliver_user_signal): Rename from handle_user_signal.
3120 (deliver_interrupt_signal): Rename from interrupt_signal.
3121 * process.c (deliver_pipe_signal): Rename from send_process_trap.
3122 (deliver_child_signal): Rename from sigchld_handler.
3123 * atimer.c (handle_alarm_signal):
3124 * data.c (handle_arith_signal):
3125 * dispnew.c (handle_window_change_signal):
3126 * emacs.c (handle_fatal_signal, handle_danger_signal):
3127 * keyboard.c (handle_input_available_signal):
3128 * keyboard.c (handle_user_signal, handle_interrupt_signal):
3129 * process.c (handle_pipe_signal, handle_child_signal):
3130 New functions, with the actual signal-handling code taken from the
3131 original respective signal handlers, sans the sporadic attempts to
3132 preserve errno, since that's now done by handle_on_main_thread.
3133 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
3134 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
3135 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3137 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3138 Move initialization of main_thread to sysdep.c's init_signals.
3139 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
3140 our usage, and simplifies the mainline code.
3141 (record_child_status_change): New static function, as a helper
3142 for handle_child_signal, and with most of the old child handler's
3144 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
3145 (handle_child_signal): Use the above.
3146 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3147 Moved here from emacs.c.
3148 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
3149 code moved here from emacs.c's main function.
3150 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
3151 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
3152 This lets callers save and restore errno properly.
3154 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3156 Remove redundant or unused things here and there.
3157 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
3158 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
3159 * editfns.c (Fcompare_buffer_substrings): Likewise.
3160 * frame.h (struct terminal, struct font_driver_list):
3161 Remove redundant declarations.
3162 * window.h (Qleft, Qright): Likewise.
3164 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3166 Do not mark objects from deleted buffers, windows and frames.
3167 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
3168 (mark_object): Likewise for windows and frames.
3170 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3172 * alloc.c (valid_lisp_object_p): Treat killed buffers,
3173 buffer_defaults and buffer_local_symbols as valid objects.
3174 Return special value to denote them.
3176 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
3178 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
3179 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
3180 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
3181 (file_name_absolute_p, Fsubstitute_in_file_name):
3182 (check_executable, check_writable, Ffile_accessible_directory_p)
3183 (Fset_file_selinux_context, Fdefault_file_modes)
3184 (Finsert_file_contents, choose_write_coding_system)
3185 (Fwrite_region, build_annotations, a_write, e_write)
3187 * filelock.c (boot_time_initialized, get_boot_time)
3188 (get_boot_time_1, lock_file_1, within_one_second):
3189 * floatfns.c (in_float):
3190 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
3191 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
3192 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
3193 * lisp.h (struct Lisp_Hash_Table.cmpfn):
3194 * window.c (compare_window_configurations):
3195 Use bool for booleans.
3196 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
3197 (Fdefault_file_modes): Now mode_t, not int, for modes.
3198 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
3199 (internal_delete_file): Now returns void, not a (boolean) int,
3200 since nobody was looking at the return value.
3201 * lisp.h, window.h: Adjust to above API changes.
3203 * xdisp.c (set_message): Simplify and reindent last change.
3205 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
3207 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
3209 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
3211 * eval.c (call_debugger): Make the function non-static so that we
3212 can call it from set_message.
3214 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
3215 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
3217 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3219 Give more-useful info on a fatal error (Bug#12328).
3220 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
3221 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
3222 of doing the work ourselves.
3223 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
3224 do most of the work.
3225 (fatal_error_backtrace): New function, taken from the guts
3226 of the old fatal_error_signal, but with a new option to output
3228 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
3229 info about the signal than just its number.
3230 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
3231 * sysdep.c: Include <execinfo.h>
3232 (emacs_backtrace): New function, taken partly from the previous
3233 code of the 'die' function.
3234 (emacs_abort): Call fatal_error_backtrace rather than abort.
3236 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
3238 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
3239 eager (load-time) macro-expansion.
3240 * lisp.mk (lisp): Add macroexp.
3242 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3244 Simplify redefinition of 'abort' (Bug#12316).
3245 Do not try to redefine the 'abort' function. Instead, redo
3246 the code so that it calls 'emacs_abort' rather than 'abort'.
3247 This removes the need for the NO_ABORT configure-time macro
3248 and makes it easier to change the abort code to do a backtrace.
3249 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
3250 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
3251 Remove; sysdep.c's emacs_abort now takes its place.
3252 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
3253 'abort' changed to use 'emacs_abort'.
3254 * msdos.c (dos_abort) [defined abort]: Remove; not used.
3255 (abort) [!defined abort]: Rename to ...
3256 (emacs_abort): ... new name.
3257 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
3258 the place of the old 'abort' in emacs.c.
3259 * w32.c, w32fns.c (abort): Do not #undef.
3260 * w32.c (emacs_abort): Rename from w32_abort.
3262 2012-09-04 Eli Zaretskii <eliz@gnu.org>
3264 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
3265 offsets[j].dv, since the y axis of the screen coordinates points
3266 down, while the y axis of the font definition coordinates points
3267 up. This fixes display of Arabic diacritics such as KASRA and
3268 KASRATAN. (Bug#11860)
3270 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3272 Be more systematic about _setjmp vs setjmp.
3273 * alloc.c (test_setjmp, mark_stack):
3274 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
3275 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
3276 (png_load, my_error_exit, jpeg_load):
3277 * process.c (send_process_trap, send_process):
3278 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
3279 The underscored versions are up to 30x faster on some hosts.
3280 Formerly, the code used setjmp+longjmp sometimes and
3281 _setjmp+_longjmp at other times, with no particular reason to
3282 prefer setjmp+longjmp.
3284 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
3286 Fix minor problem found by static checking.
3287 * buffer.c (Fdelete_all_overlays): Return nil.
3289 2012-09-03 Martin Rudalics <rudalics@gmx.at>
3291 * buffer.c (Fdelete_all_overlays): New function.
3293 2012-09-03 Chong Yidong <cyd@gnu.org>
3295 * gtkutil.c: Add extern decl for Qxft.
3297 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
3299 * emacs.c, eval.c: Use bool for boolean.
3300 * emacs.c (initialized, inhibit_window_system, running_asynch_code):

3311 All callers changed.
3312 * eval.c (interactive_p): Omit always-true boolean argument
3313 EXCLUDE_SUBRS_P. All callers changed.
3314 * dispextern.h, lisp.h: Reflect above API changes.
3315 * firstfile.c (dummy): Use the address of 'main', whose signature
3316 won't change, instead of the address of 'initialize', whose
3317 signature just changed from int to bool.
3318 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
3319 * msdos.c (fatal_error_in_progress): ... from here.
3320 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
3322 (redisplay_internal, unwind_redisplay): Simply clear
3323 REDISPLAYING_P when unwinding, instead of saving its previous,
3324 always-false value and then restoring it.
3326 Clean up some extern decls.
3327 Mostly, this hoists extern decls out of .c files and into .h files.
3328 That way, we're more likely to catch errors if the interfaces change.
3329 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
3330 declare xg_mark_data.
3331 * dispextern.h (x_frame_parm_handlers):
3333 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
3334 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)

3349 * xfont.c (x_clear_errors):
3350 * xterm.c (x_frame_parm_handlers):
3351 Remove now-redundant extern decls.
3352 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
3353 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
3355 * xfaces.c: Remove unnecessary static decls.
3356 * xterm.c (updating_frame): Remove decl of nonexistent object.
3358 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
3359 when building globals.h, as the objects that are not built on
3360 this host are not needed to compile C files on this host.
3362 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
3364 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

3378 (make_buffer_string, make_buffer_string_both)
3379 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):

3391 (set_intervals_multibyte_1, set_intervals_multibyte):
3392 * keyboard.c (decode_timer):
3393 Use bool for boolean.
3394 * intervals.h, lisp.h, systime.h: Reflect above API changes.
3395 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
3397 2012-09-02 Chong Yidong <cyd@gnu.org>
3399 * keymap.c (push_key_description): Print M-TAB as C-M-i
3402 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
3404 * makefile.w32-in (CCL_H, W32FONT_H): New macros.

3412 2012-09-01 Eli Zaretskii <eliz@gnu.org>
3414 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
3415 more than one grapheme cluster passed to the shaper: compute the
3416 offset adjustment values separately for each cluster. (Bug#11860)
3418 * image.c: Restore mistakenly removed inclusion of w32.h. Without
3419 it, GCC doesn't see prototypes of w32_delayed_load, and complains
3420 about implicit conversions from integer to pointer.
3422 2012-09-01 Daniel Colascione <dancol@dancol.org>
3424 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
3425 system used too early.
3427 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
3429 Better seed support for (random).

3458 * process.c: Include TERM_HEADER instead of listing all possible
3459 window-system headers.
3461 * nsterm.h: Remove declarations now in frame.h.
3462 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
3464 * menu.c: Include TERM_HEADER instead of listing all possible
3465 window-system headers.
3467 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
3470 * keyboard.c: Include TERM_HEADER instead of listing all possible
3471 window-system headers.
3473 * image.c: Include TERM_HEADER instead of listing all possible
3474 window-system headers. Declare Vlibrary_cache when compiling for
3477 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
3478 window system declarations.
3480 * frame.h: Move common functions here: set_frame_menubar,
3481 x_set_window_size, x_sync, x_get_focus_frame,
3482 x_set_mouse_position, x_set_mouse_pixel_position,
3483 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

3507 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
3509 Remove mark_ttys function and fix tty_display_info initialization.
3510 * lisp.h (mark_ttys): Remove prototype.
3511 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
3512 to mark_ttys because all possible values of 'top_frame' slot are
3513 the frames which are reachable from Vframe_list.
3514 * term.c (mark_ttys): Remove.
3515 (init_tty): Safely initialize 'top_frame' slot with Qnil.
3517 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
3519 Change struct frame bitfields from unsigned char to unsigned.
3520 * frame.h (struct frame): Change type of 'display_preempted',

3522 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
3523 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
3524 bitfields from unsigned char to unsigned.

3537 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
3539 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
3540 for GCC 4.7.1 x86-64.
3542 2012-08-30 Glenn Morris <rgm@gnu.org>
3544 * lread.c (init_lread): For out-of-tree builds, only add the
3545 source directory's site-lisp dir to the load-path if it exists,
3546 consistent with in-tree builds. (Bug#12302)
3548 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
3550 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize

3558 with tag. Remove return self, declare return value as void.
3559 (addString:row:): Remove return self, declare return value as void.
3560 (addSplit): Remove return self, declare return value as void.
3561 (clicked:): Remove return self, declare return value as void.
3562 Set dialog_return to button_values[seltag]. Code formatting change.
3563 (initFromContents:isQuestion:): Adjust call to process_dialog.
3564 Code formatting change.
3565 (timeout_handler:): Set timer_fired to YES.
3566 (runDialogAt:): Set timer_fired to NO.
3567 Handle click on close button as quit.
3569 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
3570 Add window_closed and button_values. Add void as return value for
3571 add(Button|String|Split). addButton takes int instead of Lisp_Object.
3572 Add process_dialog as new member.
3574 2012-08-28 Eli Zaretskii <eliz@gnu.org>
3576 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
3577 is not one of the heaps we manage. (Bug#12242)

3638 Use bool for boolean.
3639 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
3640 and remove last int (actually boolean) argument, which was always 0.
3641 All callers changed.
3642 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
3643 * dispextern.h (struct composition_it): Use bool for boolean.
3644 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
3645 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
3646 * dired.c (file_name_completion):
3647 Use bool for boolean. (This was missed in an earlier change.)
3649 2012-08-27 Martin Rudalics <rudalics@gmx.at>
3651 * window.c (Fset_window_configuration): Revert first part of
3654 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
3656 * nsterm.h (NSPanel): New class variable dialog_return.
3658 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
3659 Initialize dialog_return.
3660 (windowShouldClose:): Use stop instead of stopModalWithCode.
3661 (clicked:): Ditto, and also set dialog_return (Bug#12258).
3662 (timeout_handler:): Use stop instead of abortModal. Send a dummy
3664 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when
3667 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>
3669 * composite.c, data.c, dbusbind.c, dired.c: Use bool for booleans.
3670 * composite.c (find_composition, composition_gstring_p)
3671 (composition_reseat_it, find_automatic_composition):

3677 * dbusbind.c (xd_in_read_queued_messages):
3678 * dired.c (directory_files_internal, file_name_completion):
3679 Use bool for booleans.
3680 * dired.c (file_name_completion):
3681 * process.h (fd_callback):
3682 Omit int (actually boolean) argument. It wasn't being used.
3684 * composite.h, lisp.h: Reflect above API changes.
3686 * cmds.c, coding.c: Use bool for booleans.
3687 * cmds.c (move_point, Fself_insert_command):

3707 (Fset_coding_system_priority):
3708 * fileio.c (Finsert_file_contents):
3709 Use bool for booleans.
3710 * coding.h, lisp.h: Reflect above API changes.
3711 * coding.c: Remove unnecessary static function decls.
3712 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
3713 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
3714 not a boolean 'int', since callers never look at the return value.
3715 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
3716 * coding.h (decoding_buffer_size, encoding_buffer_size)
3717 (emacs_mule_string_char): Remove unused extern decls.
3718 (struct iso_2022_spec, struct coding_system):
3719 Use 'unsigned int : 1' for boolean fields, since there's more than one.
3720 (struct emacs_mule_spec): Remove unused field 'full_support'.
3721 All initializations removed.
3722 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
3724 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
3726 Fix spare memory change (Bug#12286).
3727 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
3728 (valid_lisp_object_p): Likewise.
3730 2012-08-27 Martin Rudalics <rudalics@gmx.at>
3732 * window.c (Fset_window_configuration): Record any window's old
3733 buffer if it's replaced (see Bug#8789). If the new current
3734 buffer doesn't appear in the selected window, go to its old
3737 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
3739 Special MEM_TYPE_SPARE to denote reserved memory.
3740 * alloc.c (enum mem_type): New memory type.
3741 (refill_memory_reserve): Use new type for spare memory.
3742 This prevents live_cons_p and live_string_p from incorrect
3743 detection of uninitialized objects from spare memory as live.
3745 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
3748 * Makefile.in (.PHONY): versioclean -> versionclean.
3750 Remove unused external symbols.
3751 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
3752 * window.c (Qwindow_valid_p, decode_valid_window):
3753 Now static, not extern.
3754 * data.c (Qinterval): Remove; unused.
3755 (syms_of_data): Do not define 'interval'.
3756 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
3757 * window.h (decode_valid_window):
3760 * character.c, charset.c, chartab.c: Use bool for booleans.
3761 * character.c (lisp_string_width, string_count_byte8)
3762 (string_escape_byte8):
3763 * charset.c (charset_map_loaded, load_charset_map, read_hex):
3764 (load_charset_map_from_file, map_charset_chars)
3765 (Fdefine_charset_internal, define_charset_internal)
3766 (Fdeclare_equiv_charset, find_charsets_in_text)
3767 (Ffind_charset_region, char_charset, Fiso_charset):

3769 (sub_char_table_set, sub_char_table_set_range)
3770 (char_table_set_range, optimize_sub_char_table)
3771 (map_sub_char_table):
3772 Use bool for boolean.
3773 * character.c (str_to_unibyte): Omit last boolean argument; it was
3774 always 0. All callers changed.
3775 * character.h, charset.h: Adjust to match previous changes.
3776 * character.h (char_printable_p): Remove decl of nonexistent function.
3777 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
3778 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
3779 are all boolean, so make them single-bit bitfields.
3781 * lisp.h (ASET): Remove attempt to detect side effects.
3782 It was meant to be temporary and it often doesn't work,
3783 because when IDX has side effects the behavior of IDX==IDX
3784 is undefined. See Stefan Monnier in
3785 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
3787 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
3789 * lisp.h (functionp): New function (extracted from Ffunctionp).
3790 (FUNCTIONP): Use it.
3791 * eval.c (Ffunctionp): Use it.
3793 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
3795 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
3796 as that's faster and simpler than static storage. Don't bother
3797 with the g_main_context_query overhead if g_main_context_pending
3798 says no events are pending.
3799 (gfds, gfds_size): Remove these static vars.
3800 (xgselect_initialize): Remove; no longer needed.
3801 All uses and decls removed.
3803 * emacs.c (fatal_error_signal_hook): Remove.
3804 All uses removed. This leftover from old code was always 0.
3806 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
3807 * casefiddle.c (casify_object, casify_region):
3808 * casetab.c (set_case_table):
3809 * category.c, category.h (word_boundary_p):
3810 * category.h (CHAR_HAS_CATEGORY):
3811 Use bool for booleans, instead of int.
3813 2012-08-25 Eli Zaretskii <eliz@gnu.org>
3815 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
3817 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
3819 On assertion failure, print backtrace if available.
3820 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
3821 (die) [ENABLE_CHECKING]: Print a backtrace if available.
3822 * Makefile.in (LIB_EXECINFO): New macro.
3825 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
3826 * bytecode.c (exec_byte_code):
3827 * callint.c (check_mark, Fcall_interactively):
3828 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
3829 (getenv_internal, sync_process_alive, call_process_exited):
3830 * lisp.h (USE_SAFE_ALLOCA):
3831 Use bool for booleans, instead of int.
3832 * lisp.h, process.h: Adjust prototypes to match above changes.
3833 * callint.c (Fcall_interactively): Don't assume the mark's
3834 offset fits in 'int'.
3836 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
3838 * buffer.c, buffer.h: Use bool for boolean.
3839 * buffer.c (reset_buffer_local_variables)
3840 (buffer_lisp_local_variables, Fset_buffer_modified_p)
3841 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
3842 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
3843 (overlay_touches_p, overlay_strings, Foverlay_put)
3844 (report_overlay_modification, call_overlay_mod_hooks):
3845 (mmap_enlarge, mmap_set_vars):
3846 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
3847 Use bool for booleans, instead of int.
3848 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
3849 since the 1-or-0 return value is always ignored anyway.
3850 (mmap_initialized_p):
3851 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
3852 * buffer.h, lisp.h: Adjust prototypes to match above changes.
3854 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
3856 * bidi.c: Use bool for boolean.
3857 This is a bit more readable, and makes the text segment of bidi.o
3858 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
3859 Presumably it's faster too.
3860 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
3862 (bidi_cache_find_level_change, bidi_cache_iterator_state)
3863 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
3864 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
3865 (bidi_explicit_dir_char, bidi_level_of_next_char)
3866 (bidi_find_other_level_edge, bidi_move_to_visually_next):
3867 Use bool for booleans, instead of int.
3868 * dispextern.h (bidi_init_it, bidi_paragraph_init)
3869 (bidi_unshelve_cache): Adjust decls to match code.
3871 2012-08-23 Martin Rudalics <rudalics@gmx.at>
3873 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
3876 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
3878 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
3879 * atimer.h: Include <stdbool.h>.
3881 2012-08-22 Dan Nicolaescu <dann@gnu.org>
3883 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
3884 compile time tests instead of run time tests on systems that do
3886 (FRAME_MAC_P): Remove leftover from deleted code.
3887 * frame.c (syms_of_frame): Remove leftover from deleted code.
3889 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
3891 * nsterm.m (insertText:): Don't clear modifiers if code is space.
3893 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
3895 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
3896 Otherwise, the compiler complains about (A?B:C) where B is void
3897 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
3898 (fontset_add): Return void, for FONTSET_ADD.
3900 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3902 * alloc.c: Use bool for booleans.
3903 (gc_in_progress, abort_on_gc)
3904 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
3905 (dont_register_blocks) [GC_MALLOC_CHECK]:
3906 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
3907 (check_string_bytes, make_specified_string, memory_full)
3908 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
3909 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
3910 (mark_stack, valid_pointer_p, make_pure_string)
3911 (Fgarbage_collect, survives_gc_p, gc_sweep):
3912 Use bool for booleans, instead of int.
3913 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
3914 Remove unused local.
3915 * alloc.c (PURE_POINTER_P):
3916 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
3917 * editfns.c (Fformat):
3918 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
3920 * fns.c (sweep_weak_table):
3921 * lisp.h (suppress_checking, push_message, survives_gc_p)
3922 (make_pure_string, gc_in_progress, abort_on_gc):
3923 * lread.c (readchar, read1):
3924 * print.c (Fprin1_to_string):
3925 * xdisp.c (push_message):
3926 Use bool for booleans affected directly or indirectly by
3929 Make recently-introduced setters macros.
3930 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
3931 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
3932 (set_fontset_default, set_fontset_fallback): Rename from their
3933 upper-case counterparts, and make them functions rather than macros.
3934 This is more consistent with the other recently-introduced setters.
3935 These don't need to be inline, since they're local.
3937 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
3939 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
3940 the loop (Bug#12247).
3942 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3944 * lisp.h (vcopy): Use memcpy rather than our own loop.
3945 This fixes a performance regression introduced by the recent
3946 addition of vcopy. This means 'vcopy' will need to be modified
3947 for a copying collector, but that's OK. Also, tighten the
3948 checking in the assertion.
3950 2012-08-21 Eli Zaretskii <eliz@gnu.org>
3952 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
3953 components for RTL text (Bug#11860). Adjust X-OFFSET of each
3954 non-base glyph for the width of the base character, according to
3955 what x_draw_composite_glyph_string_foreground expects.
3956 Generate WADJUST value according to composition_gstring_width's
3957 expectations, to produce correct width of the composed character.
3958 Reverse the sign of the DU offset produced by ScriptPlace.
3960 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3962 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
3964 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
3966 Avoid direct writes to contents member of struct Lisp_Vector.
3967 * lisp.h (vcopy): New function to copy data into vector.
3968 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
3969 * fns.c (Ffillarray): Use ASET.
3970 * keyboard.c (timer_check_2): Use AREF and ASET.
3971 (append_tool_bar_item, Frecent_keys): Use vcopy.
3972 * lread.c (read_vector): Use ASET.
3973 * msdos.c (Frecent_doskeys): Use vcopy.
3974 * xface.c (Finternal_copy_lisp_face): Use vcopy.
3975 (Finternal_merge_in_global_face): Use ASET and vcopy.
3976 * xfont.c (xfont_list_pattern): Likewise.
3978 2012-08-21 Martin Rudalics <rudalics@gmx.at>
3980 * window.c (Fwindow_point): For the selected window always return
3981 the position of its buffer's point.
3982 (Fset_window_point): For the selected window always go in its
3983 buffer to the specified position.
3985 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
3987 Setter macros for fontsets.
3988 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
3989 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
3990 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
3993 2012-08-20 Glenn Morris <rgm@gnu.org>
3995 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
3996 Don't assume that `ln -f' works.
3998 2012-08-20 Eli Zaretskii <eliz@gnu.org>
4000 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
4001 and later about non-assignments with no effect. See discussion at
4002 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
4005 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
4007 Inline setter functions for Lisp_Objects slots of struct specbinding.
4008 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
4011 2012-08-20 Martin Rudalics <rudalics@gmx.at>
4013 * window.c (select_window): Always make selected window's buffer
4016 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
4018 Use AREF and ASET for docstrings of category tables.
4019 * category.h (CATEGORY_DOCSTRING): Use AREF.
4020 (SET_CATEGORY_DOCSTRING): Use ASET.
4021 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
4023 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
4025 Inline setter functions for hash table members.
4026 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
4027 (set_hash_hash, set_hash_index): Rename with _slot suffix.
4028 (set_hash_key_and_value, set_hash_index, set_hash_next)
4029 (set_hash_hash): New functions.
4030 * charset.c, fns.c: Adjust users.
4032 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
4034 Inline getter and setter functions for per-buffer values.
4035 * buffer.h (per_buffer_default, set_per_buffer_default)
4036 (per_buffer_value, set_per_buffer_value): New functions.
4037 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
4038 * buffer.c, data.c: Adjust users.
4040 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
4042 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
4044 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
4046 Rely on <config.h> + <unistd.h> to declare 'environ',
4047 as gnulib does this if the system doesn't.
4048 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
4049 Remove declaration. MS-Windows declares it on stdlib.h which is
4050 included by conf_post.h.
4051 * emacs.c (environ) [DOUG_LEA_MALLOC]:
4052 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
4053 * vm-limit.c: Include <unistd.h>, for 'environ'.
4055 * unexaix.c, unexcoff.c: Include "mem-limits.h".
4056 (start_of_data): Remove decl; mem-limits.h provides it.
4058 * xdisp.c (handle_invisible_prop): Make it a bit faster
4059 and avoid a gcc -Wmaybe-uninitialized diagnostic.
4061 2012-08-19 Chong Yidong <cyd@gnu.org>
4063 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
4066 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
4068 * .gdbinit: Use call instead of set when calling a function in the
4071 * data.c (set_internal): Don't use set_blv_found.
4072 (Fkill_local_variable): Likewise.
4074 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
4076 * nsfont.m (ns_ascii_average_width): Ensure the string
4077 ascii_printable is initialized with a null-terminated character
4078 array. Otherwise, it can contain undesired extra characters.
4080 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
4082 port new setting code to Sun C 5.8 2005/10/13
4083 * chartab.c, lisp.h (char_table_set, char_table_set_range):

4472 Use bool, not int, for Lisp booleans.
4473 This is more natural, and on my platform (GCC 4.7.1 x86-64) it

4951 2012-08-04 Paul Eggert <eggert@cs.ucla.edu>
4953 Export DEFAULT_REHASH_* to GDB.
4954 * lisp.h (DEFAULT_REHASH_THRESHOLD, DEFAULT_REHASH_SIZE):
4955 Now constants, not macros.
4957 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
4959 Remove unnecessary casts involving pointers.
4960 These casts are no longer needed now that we assume C89 or later,
4961 since they involve casting to or from void *.
4962 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
4963 (make_pure_float, make_pure_vector):
4964 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

4970 * xfaces.c (compare_fonts_by_sort_order):
4971 * xfns.c (x_real_positions, select_visual):
4972 * xselect.c (x_stop_queuing_selection_requests)
4973 (x_get_window_property, x_get_window_property_as_lisp_data):
4974 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
4975 Remove unnecessary pointer casts.
4976 * alloc.c (record_xmalloc): New function.
4977 * lisp.h (record_xmalloc): New decl.
4978 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
4979 more like a function. This is because the pointer cast is not
4980 needed. All uses changed.
4981 * print.c (print_string, print_error_message): Avoid length recalc.
4983 Improve fix for macroexp crash with debugging (Bug#12118).
4984 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
4985 ARRAY_MARK_FLAG when checking subscripts, because ASET is
4986 not supposed to be invoked from the garbage collector.
4987 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
4988 (gc_aset): New function, which is like ASET but can be
4989 used in the garbage collector.
4990 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)
4991 (set_hash_index): Use it instead of ASET.

5002 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
5003 (map_w32_filename): Improve commentary. Simplify switch.
5004 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
5005 headers (most versions of MinGW w32api don't).
5006 (get_security_info, create_symbolic_link)
5007 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
5009 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
5010 in the argument file name.

5013 (sys_rename): Diagnose renaming of a symlink when the user doesn't
5014 have the required privileges.
5015 (get_file_security_desc_by_name): Rename from
5016 get_file_security_desc.
5017 (stat_worker): New function, with most of the guts of 'stat', and
5018 with addition of handling of symlinks and support for 'lstat'.
5019 If possible, get file's attributes and security information by
5020 handle, not by name. Produce S_IFLNK bit for symlinks, when
5021 called from 'lstat'.
5022 (stat, lstat): New functions, call 'stat_worker'.
5023 (symlink, readlink, careadlinkat): Rewritten to create and resolve
5024 symlinks when the underlying filesystem supports them.
5026 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
5028 Fix macroexp crash on Windows with debugging (Bug#12118).
5029 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
5030 checking subscripts; problem introduced with the recent
5031 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
5032 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
5033 since it's used in non-static inline functions now.
5035 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
5036 Don't assume buffer size fits in 'int'. Remove unused local.
5038 Use C99-style 'extern inline' if available.

5048 * buffer.h, category.h, character.h, charset.h, composite.h:
5049 * dispextern.h, lisp.h, systime.h:
5050 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
5051 * alloc.c (LISP_INLINE):
5052 * buffer.c (BUFFER_INLINE):
5053 * category.c (CATEGORY_INLINE):
5054 * character.c (CHARACTER_INLINE):
5055 * charset.c (CHARSET_INLINE):
5056 * composite.c (COMPOSITE_INLINE):
5057 * dispnew.c (DISPEXTERN_INLINE):
5058 * sysdep.c (SYSTIME_INLINE):
5059 Define to EXTERN_INLINE, so that the corresponding functions
5060 are compiled into code.
5061 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
5062 (INLINE_HEADER_END): New macros.
5063 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

5083 hard-coding the path separator.
5085 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
5087 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
5088 This how ASET and AREF are supposed to work, and makes
5089 it easier to think about future improvements. See
5090 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
5091 * charset.h (set_charset_attr): New function.
5092 All lvalue-style uses of CHARSET_DECODER etc. changed to use it.
5093 * lisp.h (ASET): Rewrite so as not to use AREF in an lvalue style.

5506 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
5507 enumeration constants, as PURE and HEAP are too general, and clash
5508 with other headers and sources, such as gmalloc.c and the
5509 MS-Windows system headers. All users changed.
5511 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
5513 Revert last save_excursion_save and save_excursion_restore changes.
5514 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

5527 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
5528 arms of an 'if', not using conditional expressions; otherwise GDB
5529 complains about the types in the unevaluated arm when the argument
5530 is an integer literal.
5531 (xgetint): Simplify expression.
5532 * alloc.c (gdb_make_enums_visible): New constant. This ports to
5533 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
5534 Zaretskii in <http://bugs.gnu.org/12036#13>.
5535 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
5536 needed now that we have gdb_make_enums_visible.
5537 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
5538 (enum enum_USE_LSB_TAG):
5539 New enum types, packaging up enums that need to be exported to GDB.

5581 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
5582 emacs.c, as this is a more-suitable home. Had this been done earlier
5583 the fix for 12036 would have avoided some of the problems noted in
5584 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
5585 would have been more obvious.
5586 * emacs.c: Do not include <verify.h>; no longer needed.
5587 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)

5595 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
5596 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
5597 not be usable in #if. This simplifies things.
5599 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
5601 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

5606 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
5607 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
5608 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
5609 Adjust to changes in lisp.h and emacs.c, by using
5610 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
5611 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
5612 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
5613 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
5614 instead of gdb_valbits.
5615 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
5616 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
5617 instead of gdb_array_mark_flag.
5618 (xboolvector): Get size from $->size, not $->header.size.
5619 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
5620 (xreload, hook-run, hookpost-run): Remove.
5621 * emacs.c: Include <verify.h>.
5622 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
5623 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
5625 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
5626 (gdb_USE_LSB_TAG): New enum constants.
5627 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
5628 Also define these as enum constants, so they're visible to GDB.
5629 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
5630 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
5631 as constants, so they're visible to GDB.

5634 Now enum constants, not macros, so they're visible to GDB.
5635 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
5636 more convenient now. All uses changed.
5637 (VALMASK) [USE_LSB_TAG]: Also define in this case.

5647 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
5648 add argument, tune behavior, and adjust all callers.
5650 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
5652 Use typedef for EMACS_INT, EMACS_UINT.
5653 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
5654 than macros. This simplifies debugging in the usual case, since
5655 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
5656 and it allows expressions involving EMACS_INT casts.
5657 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
5659 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

5671 Adjust buffer text indirection counters at the end of Fkill_buffer.
5672 * buffer.c (Fkill_buffer): Adjust indirection counters when the
5673 buffer is definitely dead. This should really fix an issue reported
5674 by Christoph Scholtes again. (Bug#12007).
5675 (init_buffer_once): Initialize indirection counters of
5676 buffer_defaults and buffer_local_symbols (for sanity and safety).
5678 2012-07-24 Eli Zaretskii <eliz@gnu.org>
5680 * xdisp.c (init_iterator): Don't compute dimensions of truncation
5681 and continuation glyphs on tooltip frames, leave them at zero.

5709 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
5711 Swap buffer text indirection counters in Fbuffer_swap_text.
5712 * buffer.c (Fbuffer_swap_text): Swap indirections too.
5713 This avoids crash reported by Christoph Scholtes at
5714 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
5716 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
5718 * nsmenu.m (Popdown_data): New struct.
5719 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
5721 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
5722 (initWithContentRect): Make imgView and contentView non-static
5723 and autorelease them. Also autorelease img and matrix (Bug#12005).
5724 (dealloc): Remove (Bug#12005).
5726 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
5728 Adjust consing_since_gc when objects are explicitly freed.

5741 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
5743 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
5744 as it's limited by the amount of memory, not by INT_MAX.
5746 2012-07-21 Eli Zaretskii <eliz@gnu.org>
5748 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
5749 in special-event-map. See the discussion at

5808 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
5809 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
5810 Adjust users accordingly.

6472 * s/aix4-2.h (unix): Remove; no longer needed.
6474 EMACS_TIME simplification (Bug#11875).
6475 This replaces macros (which typically do not work in GDB)

6477 The functional style also makes code easier to read and maintain.
6478 * systime.h: Include <sys/time.h> on all hosts, not just if
6479 WINDOWSNT, since 'struct timeval' is needed in general.

6495 (add_emacs_time, sub_emacs_time): New functions.
6496 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

6519 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
6520 Prefer snprintf to strncpy.
6521 * nsterm.m (ns_term_init):
6522 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
6523 * nsterm.m (ns_term_init):
6524 Avoid the need for strncpy, by using build_string or
6525 make_unibyte_string directly. Use dtoastr, not snprintf.
6526 * process.c (Fmake_network_process): Diagnose service names that
6527 are too long, rather than silently truncating them or creating
6528 non-null-terminated names.

6545 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
6546 where argument type is known to be a Lisp_Cons.

6601 O_RDONLY already includes it).
6603 Stop ns builds setting the EMACSLOADPATH environment variable.
6604 * nsterm.m (ns_load_path): Rename from ns_init_paths.
6605 Now it does not set EMACSLOADPATH, just returns the load-path string.

6607 * lread.c [HAVE_NS]: Include nsterm.h.
6608 (init_lread) [HAVE_NS]: Use ns_load_path.

6678 Move marker debugging code under MARKER_DEBUG.
6679 * marker.c (MARKER_DEBUG): Move marker debugging code under
6680 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
6681 for bootstrap with --enable-checking (~3x slowdown reported

6733 2012-07-07 Glenn Morris <rgm@gnu.org>
6735 * lread.c (load_path_check): New function, split from init_lread.
6736 (init_lread): Reorganize. Motivation:
6737 If EMACSLOADPATH is set, check/warn about that rather than the
6738 defaults, which we are not going to use. Hence we can remove
6739 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
6740 Don't warn if site-lisp directories are missing.
6741 If not installed, start from a blank load-path, since
6742 PATH_LOADSEARCH refers to the eventual installation directories.
6744 2012-07-07 Eli Zaretskii <eliz@gnu.org>
6746 Support truncation and continuation glyphs on GUI frames, when
6747 fringes are disabled. (Bug#11832)
6748 * xdisp.c (init_iterator): Get dimensions of truncation and
6749 continuation glyphs even if on GUI frames.
6750 Adjust it->last_visible_x on GUI frames when the left or right fringes,
6751 or both, are absent.
6752 (start_display, move_it_in_display_line_to): Handle the case of a
6753 GUI frame without a fringe to display continuation or truncation
6755 (insert_left_trunc_glyphs): Support GUI frames: make sure
6756 truncation glyphs overwrite enough glyphs from the current line to
6757 have sufficient space in pixels.
6758 (display_line): Support truncation and continuation glyphs on GUI
6759 frames. If some spare pixels are left on the line after inserting
6760 the truncation glyphs, fill that space with a stretch glyph of a
6761 suitably computed width.
6763 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
6764 produce_glyphs, to support GUI sessions.
6766 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
6768 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
6770 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
6772 Do not require float-time's arg to fit in time_t (Bug#11825).
6773 This works better on hosts where time_t is unsigned, and where
6774 float-time is applied to the (negative) difference between two times.
6775 * editfns.c (decode_time_components): Last arg is now double *,
6776 not int *, and means to store all the result as a double, without
6777 worrying about whether the seconds part fits in time_t.
6778 All callers changed.
6779 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
6780 All callers changed.
6781 (Ffloat_time): Do not fail merely because the specified time falls
6782 outside of time_t range.
6784 2012-07-07 Glenn Morris <rgm@gnu.org>
6786 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

6797 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6799 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
6800 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
6801 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
6802 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
6803 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
6804 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
6806 * xfont.c (compare_font_names): Redo to omit the need for casts.
6808 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
6810 * xfns.c (Fx_change_window_property): Doc fix.
6811 * w32fns.c (Fx_change_window_property): Doc fix.
6813 * w32fns.c (Fx_window_property): Accept the same arguments as the
6814 X Windows version. Doc fix.
6815 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
6817 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
6818 Eli Zaretskii <eliz@gnu.org>
6820 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
6821 Windows-specific code from nt/config.nt moved here.
6822 Obsolete settings removed.
6824 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6826 * process.c: Avoid unnecessary calls to gettime.
6827 (wait_reading_process_output): Don't get the time of day
6828 when gobbling data immediately and not waiting, as there's no need
6829 for it in that case. This removes a FIXME.
6831 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
6833 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
6834 is defined (Bug#11768).
6836 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6838 Fix marker debugging code.
6839 * marker.c (byte_char_debug_check): Do not perform the check
6840 if buffer is not multibyte.
6841 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
6842 Call byte_char_debug_check with correct arguments.
6844 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6846 Compile marker debugging code only if ENABLE_CHECKING is defined.
6847 * marker.c (byte_char_debug_check, count_markers):
6848 Use only if ENABLE_CHECKING is defined.
6849 (byte_debug_flag): Remove.
6850 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
6851 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
6853 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6855 Avoid code repetition in marker-related functions.
6856 * marker.c (attach_marker): New function.
6857 (Fset_marker, set_marker_restricted, set_marker_both)
6858 (set_marker_restricted_both): Use it.
6859 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
6860 Consistently rename charno to charpos.
6861 (marker_position): Add eassert.
6862 (marker_byte_position): Convert to eassert.
6864 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6866 Simplify list operations in unchain_overlay and unchain_marker.

6868 * marker.c (unchain_marker): Simplify. Fix comments.
6870 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6872 Introduce fast path for the widely used marker operation.
6873 * alloc.c (build_marker): New function.
6874 * lisp.h (build_marker): New prototype.
6875 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
6876 * composite.c (autocmp_chars): Likewise.
6877 * editfns.c (buildmark): Remove.
6878 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
6879 (save_restriction_save): Use build_marker.
6880 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
6881 * window.c (save_window_save): Likewise.
6883 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6885 Do not use Fdelete_overlay in delete_all_overlays
6886 to avoid redundant calls to unchain_overlay.
6887 * buffer.c (drop_overlay): New function.
6888 (delete_all_overlays, Fdelete_overlay): Use it.
6889 * minibuf.c (get_minibuffer): Fix comment.
6891 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6893 Port to OpenBSD 5.1 amd64.
6894 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
6895 This is needed for OpenBSD, and should be harmless on all BSD systems.
6896 Also, include <sys/sysctl.h>, as it should be available on all
6897 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
6898 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
6899 use p_pid member, not kp_proc.pid.
6901 2012-07-06 Glenn Morris <rgm@gnu.org>
6903 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
6905 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
6907 More xmalloc and related cleanup.
6908 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
6909 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
6910 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:

6914 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
6915 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
6916 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
6918 Omit needless casts involving void * pointers and allocation.
6919 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
6920 as the former is more robust if P's type is changed.
6921 Prefer xzalloc to xmalloc + memset 0.
6922 Simplify malloc-or-realloc to realloc.
6923 Don't worry about xmalloc returning a null pointer.
6924 Prefer xstrdup to xmalloc + strcpy.
6925 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
6927 * keyboard.c (apply_modifiers_uncached): Prefer local array to
6928 alloca of a constant.
6930 2012-07-05 Eli Zaretskii <eliz@gnu.org>
6932 * xdisp.c (display_line): Fix horizontal pixel coordinates when
6933 hscroll is larger than the line width. Fixes long and futile
6934 looping inside extend_face_to_end_of_line (on a TTY) producing
6935 glyphs that are not needed and thrown away.
6937 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
6939 * marker.c (set_marker_restricted_both): Simplify by using
6942 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
6944 * editfns.c (region_limit): Simplify by using clip_to_bounds.
6946 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
6948 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
6949 not defined (Bug#11768).
6950 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
6951 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
6952 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
6953 followed by gtk_box_set_homogeneous (Bug#11768).
6954 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
6955 (update_theme_scrollbar_width, xg_create_scroll_bar):
6956 Use gtk_scrollbar_new (Bug#11768).
6957 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
6958 (is_box_type): New function (Bug#11768).
6959 (xg_tool_item_stale_p): Call is_box_type.
6960 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
6961 with default display (Bug#11768).
6963 2012-07-05 Eli Zaretskii <eliz@gnu.org>
6965 * xdisp.c (window_hscroll_limited): New function.
6966 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
6967 coordinates when window's hscroll is set to insanely large
6970 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
6972 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
6973 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
6975 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>

7031 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
7033 * fileio.c (time_error_value): Check the right error number.
7034 Problem reported by Troels Nielsen in
7035 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
7037 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7039 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
7040 This should be fixed in a better way; see Eli Zaretskii in
7041 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
7042 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
7044 * fileio.c (time_error_value): Rename from special_mtime.
7045 The old name's problems were noted by Eli Zaretskii in
7046 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
7048 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
7049 This variable's comment says Emacs needs at least one GDB-visible
7050 symbol of type enum pvec_type, to work around GDB problems.
7051 The symbol's value doesn't matter.
7053 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
7054 that causes compilation to fail on pre-C99 compilers.
7056 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
7058 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
7059 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
7061 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
7063 * buffer.c (init_buffer_once): Fix initialization of
7064 headers for buffer_defaults and buffer_local_symbols.
7065 Reported by Juanma Barranquero <lekktu@gmail.com>.
7067 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
7069 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
7070 * lisp.h (enum pvec_type): Use fewer bits.
7071 (PSEUDOVECTOR_SIZE_BITS): New constant.
7072 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
7073 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
7074 change in pvec_type.
7075 (PSEUDOVECTOR_TYPEP): New macro.
7076 (TYPED_PSEUDOVECTORP): Use it.
7077 * fns.c (internal_equal): Adapt code to extract pvectype.
7078 * emacs.c (gdb_pvec_type): Update type.
7079 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
7080 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
7081 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
7082 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
7083 (sweep_vectors): Use it. Use local var `total_bytes' instead of
7084 abusing vector->header.next.nbytes.
7085 (live_vector_p): Use PVEC_TYPE.
7086 (mark_object): Adapt code to extract pvectype. Use switch.
7088 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7090 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
7091 Tighten new eassert a bit.
7093 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
7095 Fix compilation with --enable-gcc-warnings and -O1
7097 * doprnt.c (doprnt): Change type of tem to int, initialize
7098 to avoid compiler warning. Add eassert.
7099 * search.c (simple_search): Initialize match_byte to avoid
7100 compiler warning. Add eassert.
7102 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7104 Avoid weird behavior with large horizontal scrolls.
7105 Without this change, for example, large hscroll values would
7106 mess up Emacs's display on Fedora 15 x86, presumably due to
7107 overflows in int calculations in the display code.
7108 Also, if buffers had long lines, Emacs would freeze.
7109 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
7110 (set_window_hscroll): New function, containing the old guts of
7111 Fset_window_hscroll. Return the clipped value.
7112 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
7113 This avoids the need to check against PTRDIFF_MAX.
7115 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
7117 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
7119 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
7121 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7123 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
7124 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
7125 since GCC 4.4.6 issues a bogus warning for them.
7127 Fix bugs in file timestamp newness comparisons.
7128 * fileio.c (Ffile_newer_than_file_p):
7129 * lread.c (Fload): Use full timestamp resolution of files,
7130 not just the 1-second resolution, so that files that are only
7131 slightly newer still count as newer.
7132 * fileio.c (Ffile_newer_than_file_p): Don't assume file
7133 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
7135 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
7137 * fileio.c: Improve handling of file time marker. (Bug#11852)
7138 (special_mtime): New function.
7139 (Finsert_file_contents, Fverify_visited_file_modtime):
7140 Use it to set special mtime values consistently.
7142 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
7144 * fileio.c (Finsert_file_contents): Properly handle st_mtime
7145 marker for non-existing file. (Bug#11852)
7147 2012-07-03 Glenn Morris <rgm@gnu.org>
7149 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
7150 and did not make it into globals.h).
7152 2012-07-03 Tom Tromey <tromey@redhat.com>

7190 2012-07-03 Glenn Morris <rgm@gnu.org>
7192 * lisp.h (Frandom): Make it visible to C.
7193 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
7194 buffer for invisible buffers. (Bug#1229)
7196 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7198 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
7199 values which aren't power of 2.
7200 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
7201 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
7204 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
7206 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
7208 * alloc.c (mark_object): Revert part of last patch to use `switch'.
7210 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7212 * alloc.c (allocate_vector_block): Remove redundant
7213 calls to mallopt if DOUG_LEA_MALLOC is defined.
7214 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
7215 avoid calls to mallopt if zero_vector is returned.
7217 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7219 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
7220 is enabled, avoid dereferencing NULL current_sblock if
7223 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7225 Cleanup basic buffer management.
7226 * buffer.h (struct buffer): Change layout to use generic vector
7227 marking code. Fix some comments. Change type of 'clip_changed'
7228 to bitfield. Remove unused #ifndef old.
7229 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
7230 (GET_OVERLAYS_AT): Fix indentation.
7231 (for_each_per_buffer_object_at): New macro.
7232 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

7235 * alloc.c (allocate_buffer): Adjust to match new layout of
7236 struct buffer. Fix comment.
7237 (mark_overlay): New function.
7238 (mark_buffer): Use it. Use mark_vectorlike to mark normal
7239 Lisp area of struct buffer.
7240 (mark_object): Use it. Adjust marking of misc objects
7241 and related comments.
7243 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
7245 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
7246 wrapper that is not needed because the wrapped code is a no-op (zero
7247 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
7248 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
7250 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
7252 * alloc.c (mark_buffer): Simplify. Remove prototype.
7253 (mark_object): Add comment. Reorganize marking of vector-like
7254 objects. Use CHECK_LIVE for all vector-like objects except buffers
7255 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
7256 Avoid redundant calls to mark_vectorlike for bool vectors.
7258 2012-06-30 Glenn Morris <rgm@gnu.org>
7260 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
7262 * epaths.in (PATH_SITELOADSEARCH): New.
7263 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
7264 This is rather than relying on --enable-locallisppath elements
7265 having "site-lisp" in their names. (Bug#10208#25, 11658)
7267 2012-06-30 Eli Zaretskii <eliz@gnu.org>
7269 * w32proc.c (sys_select): Accept and ignore one more argument.
7271 * w32.c (emacs_gnutls_pull): Call select with one more argument.
7273 * sysselect.h [DOS_NT]: Don't include sys/select.h.
7274 (pselect) [!MS_DOS]: Redirect to sys_select.
7276 * sysdep.c: Don't include dos.h and dosfns.h.
7278 * process.c (sys_select):
7279 * msdos.c (sys_select): Accept one more argument and ignore it.
7281 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
7282 adapt data types and code to that.
7285 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
7286 which clashes with the gnulib function of the same name.
7288 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
7290 * font.c (font_style_to_value, font_style_symbolic)
7291 (font_prop_validate_style): Add type checks for values in
7294 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
7296 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
7299 2012-06-29 Eli Zaretskii <eliz@gnu.org>
7301 * xdisp.c (try_window_id): Undo last change.
7303 * w32.c (getwd): Adjust commentary about startup_dir.
7304 (init_environment): Always call sys_access, even in non-MSVC
7305 builds. Don't chdir to the directory of the Emacs executable.
7306 This undoes code from 1997 which was justified by the need to
7307 "avoid conflicts when removing and renaming directories". But its
7308 downside was that every relative file name was being interpreted
7309 relative to the directory of the Emacs executable, which can never
7310 be TRT. In particular, it broke sys_access when called with
7311 relative file names.
7312 (sys_access): Map GetLastError to errno.
7314 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
7316 * window.h (struct window): Change type of 'fringes_outside_margins'

7320 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
7323 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>

7326 Add QUIT to make the loop interruptible.
7328 2012-06-29 Glenn Morris <rgm@gnu.org>
7330 * charset.c (init_charset): Make lack of etc/charsets fatal.
7332 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
7334 * editfns.c (region_limit): Fix type mismatch.
7336 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
7338 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
7339 undefined. Convert from xassert to eassert.
7340 * nsmenu.m: Convert from xassert to eassert.
7341 * nsterm.m: Likewise.
7343 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
7345 * editfns.c (region_limit): Clip to narrowing (bug#11770).
7347 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
7349 Avoid integer overflow on scroll-left and scroll-right.
7350 * window.c (HSCROLL_MAX): New macro.
7351 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
7352 overflow when requested scroll falls outside ptrdiff_t range.

7356 * window.h (struct window): Change type of 'hscroll',
7357 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
7358 'last_modified' and 'last_overlay_modified' to EMACS_INT.
7359 Adjust users accordingly.
7360 * xdisp.c (try_cursor_movement): Replace type check with eassert.
7361 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
7362 from EMACS_INT to ptrdiff_t.
7363 (make_window): Omit redundant initialization.
7365 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

7369 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
7371 * window.h (struct window): Change type of 'use_time' and
7372 'sequence_number' from Lisp_Object to int.

7438 * alloc.c (allocate_string): Omit intervals initialization.
7439 * alloc.c (make_uninit_multibyte_string): Initialize intervals
7440 as in make_pure_string and make_pure_c_string.

7498 a better opportunity to optimize away calls to strlen when the
7499 function is called with compile-time constant argument.
7500 * image.c (imagemagick_error): Convert to build_string.
7501 * w32proc.c (sys_spawnve): Likewise.

7504 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
7506 Use sprintf return value instead of invoking strlen on result.
7507 In the old days this wasn't portable, since some sprintf
7508 implementations returned char *. But they died out years ago and
7509 Emacs already assumes sprintf returns int.
7510 Similarly for float_to_string.
7511 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

7518 * xfns.c (syms_of_xfns):
7519 Use sprintf or float_to_string result to avoid need to call strlen.
7520 * data.c (Fnumber_to_string):
7521 Use make_unibyte_string, since the string must be ASCII.
7522 * lisp.h, print.c (float_to_string): Now returns int length.
7523 * term.c (produce_glyphless_glyph):
7524 Use sprintf result rather than recomputing it.
7526 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
7527 * Makefile.in (ALL_CFLAGS):

7557 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
7559 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

7562 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
7564 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
7565 instead of truncating it to 63 (admittedly a generous limit).
7567 * process.c: Fix spelling and caps in comments.
7569 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>

7625 * keyboard.c (kbd_buffer_get_event):
7626 * process.c (Faccept_process_output):

7648 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
7649 Privately reported by Herbert J. Skuhra.
7650 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
7652 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,

7695 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
7697 Support higher-resolution time stamps (Bug#9000).
7698 The time stamps are only nanosecond-resolution at the C level,
7699 since that's the best that any real-world system supports now.
7700 But they are picosecond-resolution at the Lisp level, as that's
7701 easy, and leaves room for future OS improvements.
7703 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
7706 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
7707 Don't get current time unless it's needed.
7709 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
7710 now provides it if it's absent.
7711 (start_atimer): Port to higher-res time stamps.
7712 Check for time stamp overflow. Don't get current time more
7713 often than is needed.
7715 * buffer.h (struct buffer): Buffer modtime now has high resolution.
7716 Include systime.h, not time.h.
7717 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
7719 * dired.c: Include stat-time.h.
7720 (Ffile-attributes): File times now have higher resolution.
7722 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
7723 (struct image): Timestamp now has higher resolution.
7725 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
7726 has at least microseconds now. All uses removed.
7727 (update_frame, update_single_window, update_window, update_frame_1)
7728 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
7729 (duration_to_sec_usec): Remove; no longer needed.
7731 * editfns.c (time_overflow): Now extern.
7732 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
7733 (float-time, Fformat_time_string, Fcurrent_time_string)
7734 (Fcurrent_time_zone): Accept and generate higher-resolution
7736 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
7737 (decode_time_components, lisp_seconds_argument): New functions.
7738 (make_time): Now static.
7739 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
7740 Report an error if the time is invalid, rather than having the caller
7743 * fileio.c: Include <stat-time.h>
7744 (Fcopy_file): Copy higher-resolution time stamps.
7745 Prefer to set the time stamp via a file descriptor if that works.
7746 (Fset_file_times, Finsert_file_contents, Fwrite_region)
7747 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
7748 (Fvisited_file_modtime, Fset_visited_file_modtime):
7749 Support higher-resolution time stamps.
7751 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
7753 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
7755 * image.c (prepare_image_for_display, clear_image_cache)
7756 (lookup_image): Port to higer-resolution time stamps.
7758 * keyboard.c (start_polling, bind_polling_period):
7759 Check for time stamp overflow.
7760 (read_char, kbd_buffer_get_event, timer_start_idle)
7761 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
7762 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
7763 Port to higher-resolution time stamps. Do not assume time_t is signed.
7764 (decode_timer): New function. Timers are now vectors of length 9,
7765 not 8, to accommodate the picosecond component.
7766 (timer_check_2): Use it.
7768 * nsterm.m (select_timeout, timeval_subtract): Remove.
7769 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
7770 as they're a bit more accurate and handle overflow better.
7771 (ns_select): Change prototype to be compatible with pselect.
7772 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
7773 * nsterm.h (ns_select): Adjust prototype.
7775 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
7776 us-resolution time stamps.
7777 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
7779 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
7781 * lisp.h (time_overflow): New decl.
7782 (wait_reading_process_output): First arg is now intmax_t, not int,
7783 to accommodate larger waits.
7785 * process.h (struct Lisp_Process.read_output_delay):
7786 Now counts nanoseconds, not microseconds.
7787 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
7789 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
7790 (wait_reading_process_output):
7791 Port to ns-resolution time stamps.
7792 (Faccept_process_output, wait_reading_process_output):
7793 Check for time stamp overflow. Do not assume time_t is signed.
7794 (select_wrapper): Remove; we now use pselect.
7795 (Fprocess_attributes): Now generates ns-resolution time stamps.
7797 * sysdep.c: Include utimens.h. Don't include utime.h
7798 or worry about struct utimbuf; gnulib does that for us now.
7799 (gettimeofday): Remove; gnulib provides a substitute.
7800 (make_timeval): New function.
7801 (set_file_times): Now sets ns-resolution time stamps.
7802 New arg FD; all uses changed.
7803 (time_from_jiffies, ltime_from_jiffies, get_up_time)
7804 (system_process_attributes):
7805 Now returns ns-resolution time stamp. All uses changed.
7806 Check for time stamp overflow.
7808 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
7809 provides a substitute now.
7811 * systime.h: Include timespec.h rather than sys/time.h and time.h,
7812 since it guarantees struct timespec.
7813 (EMACS_TIME): Now struct timespec, so that we can support
7814 ns-resolution time stamps.
7815 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
7816 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
7817 (EMACS_USECS): Remove.
7818 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
7819 so multiply the arg by 1000 before storing it.
7820 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
7822 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
7823 Port to ns-resolution time stamps.
7824 (EMACS_TIME_NEG_P): Remove; replaced by....
7825 (EMACS_TIME_SIGN): New macro.
7826 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
7827 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
7828 (set_file_times, make_time, lisp_time_argument): Adjust signature.
7829 (make_timeval, make_lisp_time, decode_time_components): New decls.
7830 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
7831 that it mishandled time_t overflow. You can't compare by subtracting!
7832 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
7833 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
7835 * term.c: Include <sys/time.h>.
7836 (timeval_to_Time): New function, for proper overflow wraparound.
7837 (term_mouse_position, term_mouse_click): Use it.
7839 * undo.c (record_first_change): Support higher-resolution time stamps
7841 (Fprimitive_undo): Use them when restoring time stamps.
7843 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
7844 (w32_get_internal_run_time):
7845 Port to higher-resolution Emacs time stamps.
7846 (ltime): Now accepts single 64-bit integer, as that's more convenient
7849 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
7851 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
7852 for compatibility with pselect. Support ns-resolution time stamps.
7854 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
7856 * xselect.c (wait_for_property_change, x_get_foreign_selection):
7857 Check for time stamp overflow, and support ns-resolution time stamps.
7859 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
7860 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
7861 (timeval_subtract): Remove; no longer needed.
7862 (XTflash, XTring_bell, x_wait_for_event):
7863 Port to ns-resolution time stamps. Don't assume time_t is signed.
7865 2012-06-22 Chong Yidong <cyd@gnu.org>
7867 * xdisp.c (x_consider_frame_title): Revert last change.
7869 2012-06-22 Eli Zaretskii <eliz@gnu.org>
7871 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
7872 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
7873 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
7874 staticidx goes up to 1597 out of 1600 = 0x640.)
7876 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
7878 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
7879 Otherwise, the umask might be mistakenly 0 while handling input signals.
7881 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
7883 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

7889 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
7890 access to `contents' member of Lisp_Vector objects with AREF and ASET
7893 2012-06-19 Chong Yidong <cyd@gnu.org>
7895 * frame.c (delete_frame): When selecting a frame on a different
7896 text terminal, do not alter the terminal's top-frame.

7900 (unwind_format_mode_line): Restore them.
7901 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
7903 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
7904 since tty frames can be explicitly named.
7905 (prepare_menu_bars): Likewise.
7907 * term.c (Ftty_top_frame): New function.
7909 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
7911 Port byte-code-meter to modern targets.
7912 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
7913 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
7914 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
7915 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
7916 (METER_1, METER_2): Simplify.
7918 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
7920 * data.c (Fdefalias): Return `symbol' (bug#11686).
7922 2012-06-18 Martin Rudalics <rudalics@gmx.at>
7924 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
7925 gets killed during executing of this function (Bug#11665).
7926 Try to always return Qt when the buffer has been actually killed.
7927 (Vkill_buffer_query_functions): In doc-string say that functions
7928 run by this hook should not change the current buffer.
7930 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
7932 Fix recently-introduced process.c problems found by static checking.
7933 * process.c (write_queue_push, write_queue_pop, send_process):
7934 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.
7935 (write_queue_pop): Fix pointer signedness problem.
7936 (send_process): Remove unused local.
7938 2012-06-17 Chong Yidong <cyd@gnu.org>

7941 frames that are not on top.
7943 2012-06-17 Troels Nielsen <bn.troels@gmail.com>
7945 * process.c (make_process): Initialize write_queue.
7946 (write_queue_push, write_queue_pop): New functions.

7950 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
7952 * lisp.h (eassert): Assume C89 or later.
7953 This removes the need for CHECK.
7954 (CHECK): Remove. Its comments about always evaluating its
7955 argument were confusing, as 'eassert' typically does not evaluate
7958 * coding.c (produce_chars): Use ptrdiff_t, not int.
7960 * xterm.c (x_draw_underwave): Check for integer overflow.
7961 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.
7963 2012-06-17 Jan Djärv <jan.h.d@swipnet.se>
7965 * nsterm.m (x_free_frame_resources): Move xfree so freed memory isn't

8052 2012-06-16 Eli Zaretskii <eliz@gnu.org>
8054 * xdisp.c (set_cursor_from_row): Don't dereference glyphs_end.
8055 If all the glyphs of the glyph row came from strings, and we have no
8056 cursor positioning clues, put the cursor on the first glyph of the

8083 (LISP_INT_TAG, case_Lisp_Int, LISP_STRING_TAG, LISP_INT_TAG_P)
8084 (LISP_INT1_TAG, enum Lisp_Type, XINT, XUINT, make_number):
8085 Simplify under the assumption that USE_2_TAGS_FOR_INTS is defined.
8086 (INTTYPEBITS): New macro, for clarity.
8087 (INTMASK, MOST_POSITIVE_FIXNUM): Use it.
8088 (LISP_INT1_TAG, LISP_STRING_TAG, LISP_INT_TAG_P):

8113 * frame.c (delete_frame): Remove outdated comment.
8114 * w32fns.c (Fw32_register_hot_key): Use XLI instead of checking
8115 USE_LISP_UNION_TYPE.

8125 2012-06-13 Glenn Morris <rgm@gnu.org>
8127 * s/usg5-4-common.h, src/s/unixware.h:
8128 Remove define/undef of HAVE_SYSV_SIGPAUSE (not used since 2010-05-04).
8130 * s/gnu.h (POSIX_SIGNALS): Remove (not used since 2010-05-04).
8132 2012-06-13 Paul Eggert <eggert@cs.ucla.edu>
8134 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
8135 * alloc.c (make_number) [!defined make_number]:
8136 Remove, as lisp.h always defines this now.
8137 (mark_maybe_pointer): Simplify since USE_LSB_TAG is always defined now.
8138 (roundup_size): Verify that it is a power of 2.
8139 * data.c (Fmake_variable_buffer_local, Fmake_local_variable):

8141 * lisp.h (USE_LSB_TAG): Allow the builder to compile with
8142 -DUSE_LSB_TAG=0, to override the automatically-selected default.
8143 USE_LSB_TAG now is always defined to be either 0 or 1.
8145 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
8146 code works fine either way, and efficiency is not a concern here,
8147 as the union type is for debugging, not for production.
8148 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
8149 Use an inline function on all platforms when using the union type,
8150 since this is simpler and 'static inline' can be used portably
8152 (LISP_INITIALLY_ZERO): New macro.
8153 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
8154 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

8294 * doprnt.c (doprnt): Truncate multibyte char correctly.
8295 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
8296 would mishandle a string argument "Xc" if X was a multibyte
8297 character of length 2: it would truncate after X's first byte
8298 rather than including all of X.
8300 2012-06-06 Chong Yidong <cyd@gnu.org>
8302 * buffer.c (word_wrap): Doc fix.

8355 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
8357 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
8360 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
8362 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
8364 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
8366 For a 'struct window', replace some Lisp_Object fields to
8367 bitfields where appropriate, remove unused fields.
8368 * window.h (struct window): Remove unused 'last_mark_x' and
8369 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
8370 change its type from Lisp_Object to bitfield.
8371 Change type of 'force_start', 'optional_new_start',
8372 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
8373 fields from Lisp_Object to bitfield. Adjust users accordingly.
8375 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
8377 Pacify gcc -Wdouble-precision when using Xaw.

8379 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
8380 Use 'float' consistently, rather than 'float' in most places
8381 and 'double' in a couple of places.
8383 2012-05-31 Eli Zaretskii <eliz@gnu.org>
8385 * xdisp.c (handle_stop): Detect whether we have overlay strings
8386 loaded by testing it->current.overlay_string_index to be
8387 non-negative, instead of checking whether n_overlay_strings is
8388 positive. (Bug#11587)
8390 2012-05-31 Chong Yidong <cyd@gnu.org>
8392 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

8398 * search.c (search_buffer): Remove calls to
8399 r_alloc_inhibit_buffer_relocation, as it is now called by
8400 maybe_unify_char, which was the cause of relocation of buffer text
8403 2012-05-31 Eli Zaretskii <eliz@gnu.org>
8405 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
8406 for the duration of call to load_charset, to avoid problems with
8407 callers of maybe_unify_char that access buffer text through C
8410 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
8411 decrement the inhibition flag, instead of just setting or
8414 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
8416 Remove obsolete '#define static' cruft.
8417 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
8418 This #undef was "temporary" in 2000; it is no longer needed
8419 now that '#define static' has gone away.
8420 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
8421 (gray_bitmap_bits): Remove; no longer needed.
8422 All uses replaced with definiens.
8423 * xterm.c: Include "bitmaps/gray.xbm".
8425 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
8427 Clean up __executable_start, monstartup when --enable-profiling.
8428 The following changes affect the code only when profiling.

8430 Define only on platforms that need it.
8431 * emacs.c: Include <sys/gmon.h> when profiling.
8432 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.

8434 (safe_bcopy): Remove decl; no longer has that name.
8435 (main): Coalesce #if into single bit of code, for simplicity.

8465 Do not create empty overlays with the evaporate property (Bug#9642).
8466 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
8467 Bug#9642, but explicitly check that the buffer the overlay would
8468 be moved to is live and rearrange lines to make sure that errors
8469 will not put the overlay in an inconsistent state.
8470 (Fdelete_overlay): Cosmetics.
8472 2012-05-28 Eli Zaretskii <eliz@gnu.org>
8474 * w32term.c (my_bring_window_to_top): New function.

8486 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
8488 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
8489 This avoids undefined behavior that might cause the eassert
8490 to not catch an out-of-range value.
8492 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
8494 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

8508 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
8509 Only r_alloc_inhibit_buffer_relocation needed to be added;
8510 the others were already declared.
8512 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
8513 before checking whether it's out of range. Put the check inside
8515 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.

8525 defined on ralloc.c.
8527 * buffer.c [REL_ALLOC]: Remove prototypes of

8533 * search.c (search_buffer): Use it to inhibit relocation of buffer
8534 text while re_search_2 is doing its job, because re_search_2 is
8535 passed C pointers to buffer text. (Bug#11519)
8537 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
8540 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator

8545 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
8548 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
8550 Fix coding-related core dumps with gcc -ftrapv.
8551 The code was computing A - B, where A and B are pointers, and B is
8552 random garbage. This can lead to core dumps on platforms that
8553 have special pointer registers, and it also leads to core dumps on
8554 x86-64 when compiled with gcc -ftrapv. The fix is to compute
8555 A - B only when B is initialized properly.
8556 * coding.c (coding_set_source, coding_set_destination): Return void.
8557 (coding_change_source, coding_change_destinations): New functions,
8558 with the old behaviors of coding_set_source and coding_set_destination.

8563 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
8565 2012-05-26 Eli Zaretskii <eliz@gnu.org>
8567 Extend mouse support on W32 text-mode console.
8568 * xdisp.c (draw_row_with_mouse_face):
8569 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
8571 * w32console.c: Include window.h.
8572 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
8574 (initialize_w32_display): Initialize mouse-highlight data.
8576 * w32inevt.c: Include termchar.h and window.h.
8577 (do_mouse_event): Support mouse-autoselect-window. When the mouse
8578 moves, call note_mouse_highlight. If help_echo changed, call
8579 gen_help_event to produce help-echo message in the echo area.
8580 Call clear_mouse_face if mouse_face_hidden is set in the mouse
8583 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
8585 * lread.c (read1): Simplify slightly to avoid an overflow warning
8586 with GCC 4.7.0 on x86-64.
8588 2012-05-26 Eli Zaretskii <eliz@gnu.org>

8606 (allocate_pseudovector):
8607 Use int, not EMACS_INT, where int is wide enough.

8629 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8630 (validate_region): Omit unnecessary test for b <= e,
8631 since that's guaranteed by the previous test.
8632 (adjust_overlays_for_delete): Avoid pos + length overflow.
8633 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
8634 (report_overlay_modification):
8635 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
8636 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):

8640 * buffer.h: Adjust decls to match defn changes elsewhere.

8645 not int, to avoid needless 32-bit limit on 64-bit hosts.
8646 (exec_byte_code): Use tighter memory-full test, one that checks
8647 for alloca overflow. Don't compute the address of the object just
8648 before an array, as that's not portable. Use EMACS_INT, not
8649 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
8650 * callint.c (Fcall_interactively):
8651 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

8662 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
8663 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8664 (casify_object): Avoid integer overflow when overallocating buffer.
8665 * casetab.c (set_identity, shuffle): Prefer int to unsigned when

8668 * category.h (CATEGORYP): Don't assume arg is nonnegative.
8669 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
8670 integers are now checked earlier. All uses replaced with XINT.
8672 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8673 For CCL_MapSingle, check that content and value are in int range.

8675 Check that Vcode_version_map_vector is a vector.
8676 (resolve_symbol_ccl_program): Check that vector header is in range.
8677 Always copy the vector, so that we can check its contents reliably
8678 now rather than having to recheck each instruction as it's being
8679 executed. Check that vector words fit in 'int'.
8680 (ccl_get_compiled_code, Fregister_ccl_program)
8681 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
8682 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

8684 contents are in range.
8685 (Fccl_execute_on_string): Check that status is in range.
8686 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
8687 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
8688 Accept and return EMACS_INT, not int, because callers can pass values

8695 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

8697 avoid mishandling large integers.

8709 Don't assume unsigned int fits into fixnum, or that fixnum fits
8710 into unsigned int. Don't require max_code to be a valid fixnum;
8711 that's not true for gb10830 4-byte on a 32-bit host. Allow
8712 invalid_code to be a cons, for the same reason. Require code_offset
8713 to be a character. Avoid int overflow if max_char is close
8715 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
8716 this is intended anyway and avoids some undefined behavior.
8717 (load_charset_map): Pass unsigned, not int, as 2nd arg of
8718 INDEX_TO_CODE_POINT, as that's what it expects.
8719 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
8720 * charset.h (DECODE_CHAR): Return int, not unsigned;
8721 this is what was intended anyway, and it avoids undefined behavior.
8722 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
8723 integer-overflow issues.
8724 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
8725 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
8726 where the argument is EMACS_INT, and this behavior is not intended.
8727 * chartab.c (Fmake_char_table, Fset_char_table_range)
8728 (uniprop_get_decoder, uniprop_get_encoder):
8729 Don't assume fixnum fits in int.
8730 * cmds.c (move_point): New function, that does the gist of
8731 Fforward_char and Fbackward_char, but does so while checking
8732 for integer overflow more accurately.
8733 (Fforward_char, Fbackward_char): Use it.
8734 (Fforward_line, Fend_of_line, internal_self_insert)
8735 (internal_self_insert):
8736 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

9338 (last_escape_glyph_face_id, last_glyphless_glyph_face_id):
9339 (handle_tool_bar_click):
9340 Use int, not unsigned, since we prefer signed and the signedness
9341 doesn't matter here.
9342 (get_next_display_element, next_element_from_display_vector):
9343 Use int, not EMACS_INT, when int is wide enough.
9344 (start_hourglass): Use duration_to_sec_usec to do proper
9345 overflow checking on durations.

9383 * xterm.c (x_x_to_emacs_modifiers):
9384 Don't assume EMACS_INT overflows nicely into int.

9392 rather than rolling our own approximation.
9393 (SCROLL_BAR_VEC_SIZE): Remove; not used.
9395 2012-05-25 Glenn Morris <rgm@gnu.org>
9397 * lisp.mk (lisp): Update for more files being compiled now.
9399 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
9401 * lread.c: Remove `read_pure' which makes no difference.
9402 (read_pure): Remove var.
9403 (unreadpure): Remove function.
9404 (readevalloop): Don't call read_list with -1 flag.
9405 (read1, read_vector): Don't test read_pure any more.
9406 (read_list): Simplify.

9417 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
9419 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
9422 This directory predates autoconf and is no longer needed nowadays.
9423 Move its few remaining bits of functionality to where they're needed.
9424 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:

9433 (EMACS_UINT): Define unconditionally now.
9434 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
9435 (BITS_PER_EMACS_INT): New constants, replacing
9436 what used to be in config.h, but not useful in #if.
9437 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
9438 define them any more.
9439 (VAL_MAX): New macro.
9441 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
9442 BITS_PER_EMACS_INT, in #if.
9443 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
9444 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
9445 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
9446 * s/ms-w32.h (DATA_START):
9447 Move here from removed file m/intel386.h.
9448 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
9449 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
9451 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
9453 Assume C89 or later.

9462 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
9463 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
9464 * xterm.c (input_signal_count): Assume volatile works.
9466 2012-05-21 Ken Brown <kbrown@cornell.edu>
9468 * xgselect.c (xg_select): Fix first argument in call to 'select'
9471 2012-05-20 Ken Brown <kbrown@cornell.edu>
9473 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
9474 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
9476 2012-05-19 Ken Brown <kbrown@cornell.edu>
9478 * xfns.c (x_in_use): Remove `static' qualifier.
9479 * xterm.h (x_in_use): Declare.
9480 * xgselect.c: Include xterm.h.
9481 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
9482 and `display_arg' (bug#9754).
9484 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
9486 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
9488 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
9489 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
9491 2012-05-18 Eli Zaretskii <eliz@gnu.org>
9493 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
9495 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
9496 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
9498 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
9499 reference to image_cache->refcount.
9500 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
9502 2012-05-17 Juri Linkov <juri@jurta.org>
9504 * search.c (Fword_search_regexp, Fword_search_backward)
9505 (Fword_search_forward, Fword_search_backward_lax)
9506 (Fword_search_forward_lax): Move functions to isearch.el
9507 (bug#10145, bug#11381).
9509 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
9511 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
9513 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
9515 * lread.c (init_obarray): Declare Qt and Qnil as special.
9517 2012-05-14 Glenn Morris <rgm@gnu.org>
9519 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
9520 Put "libexec" before "bin", for the sake of init_callproc_1.
9522 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
9524 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
9526 * unexaix.c: Port to more-recent AIX compilers.
9527 (report_error, report_error_1, make_hdr, copy_sym)
9528 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
9529 Make arguments const char *, not char *, to avoid violations of C
9530 standard and to fix some AIX warnings reported by Gilles Pion.
9532 2012-05-14 Eli Zaretskii <eliz@gnu.org>
9534 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
9535 already have overlays loaded.
9536 (handle_single_display_spec): Before returning without displaying
9537 fringe bitmap, synchronize the bidi iterator with the main display
9538 iterator, by calling iterate_out_of_display_property.
9539 (iterate_out_of_display_property): Detect buffer iteration by
9540 testing that it->string is a Lisp string.
9541 (get_next_display_element): When the current object is exhausted,
9542 and there's something on it->stack, call set_iterator_to_next to
9543 proceed with what's on the stack, instead of returning zero.
9544 (set_iterator_to_next): If called at the end of a Lisp string,
9545 proceed to consider_string_end without incrementing string
9546 position. Don't increment display vector index past the end of
9547 the display vector. (Bug#11417)
9548 (pos_visible_p): Don't report a position visible when move_it_to
9549 stopped at the last line of window, which happens to be scanned
9550 backwards by the bidi iteration. (Bug#11464)
9552 2012-05-14 Eli Zaretskii <eliz@gnu.org>
9554 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
9555 and right-margin display specs even if the spec is invalid or we
9556 are on a TTY, and thus unable to display on the fringes.
9557 That's because the text with the property will not be displayed anyway,
9558 so we need to signal to the caller that this is a "replacing"
9559 display spec. This fixes display when the spec is invalid or we
9562 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
9564 * unexaix.c (make_hdr): Fix typo in prototype.
9565 This bug broke the build on AIX. Problem reported by Gilles Pion.
9567 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
9569 * keyboard.c (kbd_buffer_get_event): Read special events also in
9570 batch mode. (Bug#11415)
9572 2012-05-12 Glenn Morris <rgm@gnu.org>
9574 * ns.mk: Update for ns_appbindir no longer having trailing "/".
9576 2012-05-12 Eli Zaretskii <eliz@gnu.org>
9578 * lisp.mk (lisp): Add newcomment.elc.
9580 2012-05-12 Glenn Morris <rgm@gnu.org>
9582 * Makefile.in (MKDIR_P): New, set by configure.
9583 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
9585 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
9587 Remove unused function hourglass_started.
9588 * dispextern.h (hourglass_started):
9589 * w32fns.c (hourglass_started):
9590 * xdisp.c (hourglass_started): Remove.
9592 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
9594 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
9595 Update dependencies.
9597 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
9599 * xgselect.c (xg_select): Put maxfds+1 into a var.
9600 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
9602 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
9604 2012-05-10 Dave Abrahams <dave@boostpro.com>
9606 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
9607 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
9609 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
9611 * dbusbind.c (xd_registered_buses): New internal Lisp object.
9612 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
9613 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
9614 Initialize xd_registered_buses.
9616 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
9618 Untag more efficiently if USE_LSB_TAG.
9619 This is based on a proposal by YAMAMOTO Mitsuharu in
9620 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
9621 For an admittedly artificial (nth 8000 longlist) benchmark on
9622 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
9623 Emacs's overall text size by 1%.
9624 * lisp.h (XUNTAG): New macro.
9625 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
9626 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
9627 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
9628 * eval.c (Fautoload):
9629 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
9630 * frame.h (XFRAME): Use XUNTAG.
9632 Port recent dbusbind.c changes to 32-bit --with-wide-int.
9633 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
9634 Remove unportable assumptions about print widths of types like
9636 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
9637 intptr_t when converting between pointer and integer, to avoid GCC
9638 warnings about wrong width.
9640 2012-05-09 Eli Zaretskii <eliz@gnu.org>
9642 * w32proc.c (new_child): Force Windows to reserve only 64KB of
9643 stack for each reader_thread, instead of defaulting to 8MB
9644 determined by the linker. This avoids failures in creating
9645 subprocesses on Windows 7, see the discussion in this thread:
9646 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
9648 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
9650 Fix up display of the *Minibuf-0* buffer in the mini window.
9651 * keyboard.c (read_char): Don't clear the echo area if there's no
9653 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
9654 contents of *Minibuf-0*) if there's no message displayed in its stead.
9656 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
9658 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
9661 2012-05-06 Chong Yidong <cyd@gnu.org>
9663 * lisp.mk (lisp): Update.
9665 2012-05-05 Jim Meyering <meyering@redhat.com>
9667 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
9669 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
9671 * data.c (PUT_ERROR): New macro.
9672 (syms_of_data): Use it. Add new error type `user-error'.
9673 * undo.c (user_error): New function.
9674 (Fprimitive_undo): Use it.
9675 * print.c (print_error_message): Adjust print style for `user-error'.
9676 * keyboard.c (user_error): New function.
9677 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
9679 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
9681 Do not limit current-time-string to years 1000..9999.
9682 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
9683 (Fcurrent_time_string): Support any year that is supported by the
9684 underlying localtime representation. Don't use asctime, as it
9685 has undefined behavior for years outside the range -999..9999.
9687 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
9689 Fix race conditions involving setenv, gmtime, localtime, asctime.
9690 Without this fix, interrupts could mess up code that uses these
9691 nonreentrant functions, since setting TZ invalidates existing
9692 tm_zone or tzname values, and since most of these functions return
9693 pointers to static storage.
9694 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
9695 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
9696 Grow the critical sections to include not just invoking
9697 localtime/gmtime, but also accessing these functions' results
9698 including their tm_zone values if any, and any related TZ setting.
9699 (format_time_string): Last arg is now struct tm *, not struct tm **,
9700 so that the struct tm is saved in the critical section.
9701 All callers changed. Simplify allocation of initial buffer, partly
9702 motivated by the fact that memory allocation needs to be outside
9703 the critical section.
9705 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
9707 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
9708 with RESET_INTERVAL.
9710 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
9711 Remove duplicated buffer name initialization.
9713 2012-05-02 Jim Meyering <jim@meyering.net>
9715 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
9717 * xfns.c (x_window): Use xstrdup (Bug#11375).
9719 2012-05-02 Eli Zaretskii <eliz@gnu.org>
9721 * xdisp.c (pos_visible_p): If already at a newline from the
9722 display string before the 'while' loop, don't walk back the glyphs
9723 from it3.glyph_row. Solves assertion violation when the display
9724 string begins with a newline (egg.el). (Bug#11367)
9726 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
9728 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
9731 2012-05-01 Glenn Morris <rgm@gnu.org>
9733 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
9734 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
9735 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
9736 All were removed before 23.1.
9738 * dispnew.c: Remove HAVE_LIBNCURSES test;
9739 it is always true on relevant platforms.
9741 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
9742 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
9744 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
9746 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
9748 * .gdbinit (xpr): Remove checks for no longer existing misc types.
9749 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
9752 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
9754 Do not avoid creating empty evaporating overlays (Bug#9642).
9755 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
9756 That is, do not delete an evaporating overlay if it becomes
9757 empty after its bounds are adjusted to fit within its buffer.
9758 This fix caused other problems, and I'm reverting it until we get
9759 to the bottom of them.
9761 2012-04-27 Chong Yidong <cyd@gnu.org>
9763 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
9765 2012-04-27 Eli Zaretskii <eliz@gnu.org>

9823 * buffer.c (Fmove_overlay): Delete an evaporating overlay
9824 if it becomes empty after its bounds are adjusted to fit within
9825 its buffer. Without this fix, in a nonempty buffer (let ((o
9826 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
9827 yields an empty overlay that has the evaporate property, which is
9828 not supposed to happen.

9945 * sysdep.c [__FreeBSD__]: Minor cleanups.
9946 (list_system_processes, system_process_attributes) [__FreeBSD__]:
9947 Use Emacs indenting style more consistently. Avoid some casts.
9948 Use 'double' consistently rather than mixing 'float' and 'double'.

9973 * process.c (wait_reading_process_output): If EIO occurs on a pty,
9974 set the status to "failed" and ensure that sentinel is run.
9976 2012-04-20 Glenn Morris <rgm@gnu.org>
9978 * process.c (Fset_process_inherit_coding_system_flag)

10032 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
10033 (NEED_MEM_INSERT): New macro.
10034 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
10035 Remove one incorrect comment and fix another.

10049 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
10050 Remove decls. This fixes an "It stinks!".

10102 2012-04-11 Daniel Colascione <dancol@dancol.org>
10104 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
10105 against is gone. It's better to use vfork now so that when Cygwin
10106 gains a new, working vfork, we use it automatically (bug#10398).
10108 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

10158 (Fdefvar): Caller changed.
10160 * callint.c (Finteractive, Fcall_interactively):
10161 * minibuf.c (Fread_variable): Callers changed.
10163 2012-04-09 Eli Zaretskii <eliz@gnu.org>
10165 * xdisp.c (set_cursor_from_row): If the display string appears in
10166 the buffer at position that is closer to point than the position
10167 after the display string, display the cursor on the first glyph of
10168 the display string. Fixes cursor display when a 'display' text
10169 property immediately follows invisible text. (Bug#11094)
10171 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
10173 composite.c: use 'double' consistently
10174 * composite.c (get_composition_id): Use 'double' consistently
10175 instead of converting 'float' to 'double' and vice versa; this is
10176 easier to understand and avoids a GCC warning.
10178 2012-04-09 Glenn Morris <rgm@gnu.org>
10180 * Makefile.in: Generate leim-list with bootstrap-emacs, in
10181 preparation for dumping it with emacs. (Bug#4789)

10209 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
10211 Fix typo that broke non-Windows builds.
10212 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
10214 2012-04-07 Eli Zaretskii <eliz@gnu.org>
10216 Support building on MS-Windows with libxml2.
10218 * makefile.w32-in (OBJ2): Add xml.$(O).
10219 (GLOBAL_SOURCES): Add xml.c.
10220 ($(BLD)/xml.$(O)): New dependency list.
10222 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
10223 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
10224 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
10225 [!WINDOWSNT]: New macros.
10226 (init_libxml2_functions, libxml2_loaded_p): New functions.
10227 (parse_region): Call fn_xmlCheckVersion instead of using the macro
10228 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
10229 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
10230 Calls xmlCleanupParser only if libxml2 was loaded (or statically
10232 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
10233 Call init_libxml2_functions before calling libxml2 functions.
10234 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
10236 * emacs.c: Don't include libxml/parser.h.
10237 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
10238 xmlCleanupParser directly.
10240 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
10242 2012-04-07 Eli Zaretskii <eliz@gnu.org>
10244 * indent.c (Fvertical_motion): If there is a display string at
10245 point, use it.vpos to compute how many lines to backtrack after
10246 move_it_to point. (Bug#11133)
10248 2012-04-06 Eli Zaretskii <eliz@gnu.org>
10250 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
10251 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
10252 about subtle differences between FETCH_CHAR* and STRING_CHAR*
10253 macros related to unification of CJK characters. For the details,
10254 see the discussion following the message here:
10255 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
10257 2012-04-04 Chong Yidong <cyd@gnu.org>
10259 * keyboard.c (Vdelayed_warnings_list): Doc fix.
10261 2012-04-01 Eli Zaretskii <eliz@gnu.org>
10263 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
10264 instead of alloca. (Bug#11138)
10266 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
10268 * w32menu.c (is_simple_dialog): Properly check lisp types.
10271 2012-03-31 Eli Zaretskii <eliz@gnu.org>
10273 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
10274 position we get to after a call to move_it_to fails the
10275 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
10276 only if we wind up in a string from display property. (Bug#11063)
10278 * window.c (Fdelete_other_windows_internal): Invalidate the row
10279 and column information about mouse highlight, so that redisplay
10280 restores it after reallocating the glyph matrices. (Bug#7464)
10282 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
10283 string comes from a `display' text property, use the buffer
10284 position of that property as if we actually saw that position in
10286 (move_it_by_lines): Remove the assertion that
10287 "it->current_x == 0 && it->hpos == 0" which can be legitimately
10288 violated when there's a before-string at the beginning of a line.
10291 2012-03-30 Eli Zaretskii <eliz@gnu.org>
10293 * xdisp.c (append_space_for_newline): If the default face was
10294 remapped, use the remapped face for the appended newline.
10295 (extend_face_to_end_of_line): Use the remapped default face for
10296 extending the face to the end of the line.
10297 (display_line): Call extend_face_to_end_of_line when the default
10298 face was remapped. (Bug#11068)
10300 2012-03-29 Eli Zaretskii <eliz@gnu.org>
10302 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
10304 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
10306 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
10308 2012-03-27 Glenn Morris <rgm@gnu.org>
10310 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
10313 2012-03-26 Kenichi Handa <handa@m17n.org>
10315 * dispextern.h (struct glyph): Fix previous change. Change the
10316 bit length of glyphless.ch to 25 (Bug#11082).
10318 2012-03-26 Chong Yidong <cyd@gnu.org>
10320 * keyboard.c (Vselection_inhibit_update_commands): New variable.
10321 (command_loop_1): Use it; inhibit selection update for
10322 handle-select-window too (Bug#8996).
10324 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
10326 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
10328 2012-03-25 Kenichi Handa <handa@m17n.org>
10330 * dispextern.h (struct glyph): Change the bit length of
10331 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
10333 2012-03-24 Eli Zaretskii <eliz@gnu.org>
10335 * s/ms-w32.h (tzname): Include time.h before redirecting to
10336 _tzname. Fixes the MSVC build. (Bug#9960)
10338 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
10340 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
10343 * xterm.c (XTread_socket): Only modify handling_signal if
10344 !SYNC_INPUT. (Bug#11080)
10346 2012-03-23 Eli Zaretskii <eliz@gnu.org>
10348 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
10349 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
10350 when fetching a multibyte character consumes more bytes than
10351 CHAR_BYTES returns, due to unification of CJK characters in
10352 string_char. (Bug#11073)
10354 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
10356 * process.c (wait_reading_process_output): Handle pty disconnect
10357 by refraining from sending oneself a SIGCHLD (bug#10933).
10359 2012-03-22 Chong Yidong <cyd@gnu.org>

10364 Mark string as coming from a prefix property.
10365 (handle_face_prop): Use default face for prefix strings (Bug#4281).
10366 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
10368 2012-03-21 Chong Yidong <cyd@gnu.org>
10370 * xfaces.c (Vface_remapping_alist): Doc fix.
10372 2012-03-20 Eli Zaretskii <eliz@gnu.org>
10374 * w32proc.c (Fw32_set_console_codepage)
10375 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
10378 2012-03-20 Chong Yidong <cyd@gnu.org>
10380 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
10381 to reflect default non-nil value of redisplay-dont-pause.
10383 2012-03-19 Kenichi Handa <handa@m17n.org>
10385 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
10386 it fit in a valid range (Bug#11003).
10388 2012-03-18 Eli Zaretskii <eliz@gnu.org>
10390 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
10391 that is not from display property, accept the row as a "cursor
10392 row" if one of the string's character has a non-nil `cursor'
10393 property. Fixes cursor positioning when there are newlines in
10394 overlay strings, e.g. in icomplete.el. (Bug#11035)
10396 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
10398 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
10400 2012-03-12 Chong Yidong <cyd@gnu.org>
10402 * eval.c (inhibit_lisp_code): Rename from
10403 inhibit_window_configuration_change_hook; move from window.c.
10405 * xfns.c (unwind_create_frame_1, Fx_create_frame):
10406 * window.c (run_window_configuration_change_hook)
10407 (syms_of_window): Callers changed.

10413 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
10415 2012-03-10 Chong Yidong <cyd@gnu.org>
10417 * frame.c (other_visible_frames): Don't assume the selected frame
10418 is visible (Bug#10955).
10420 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
10422 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).

10426 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
10427 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
10430 2012-03-03 Glenn Morris <rgm@gnu.org>
10432 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
10434 2012-03-02 Eli Zaretskii <eliz@gnu.org>
10436 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
10437 position past the first glyph_row that ends at ZV. (Bug#10902)
10438 (redisplay_window, next_element_from_string): Fix typos in
10440 (redisplay_window): Pass to move_it_vertically the margin in
10441 pixels, not in screen lines.
10443 2012-03-02 Glenn Morris <rgm@gnu.org>
10445 * buffer.c (buffer-list-update-hook): Doc fix.
10447 2012-02-29 Eli Zaretskii <eliz@gnu.org>
10449 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
10450 push_it before setting up the iterator for the first overlay
10451 string, even if we have an empty string loaded.
10452 (next_overlay_string): If there's an empty string on the iterator
10453 stack, pop the stack. (Bug#10903)
10455 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
10457 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
10458 Suggested by Stefan Monnier in
10459 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
10460 * alloc.c (widen_to_Lisp_Object): New static function.
10461 (mark_memory): Also mark Lisp_Objects by fetching pointer words
10462 and widening them to Lisp_Objects. This would work even if
10463 USE_LSB_TAG is defined and wide integers are used, which might
10464 happen in a future version of Emacs.
10466 2012-02-25 Chong Yidong <cyd@gnu.org>
10468 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
10471 * xselect.c (Fx_selection_exists_p): Doc fix.
10472 (x_clipboard_manager_save_all): Print an informative message
10473 before saving to clipboard manager.
10475 2012-02-24 Chong Yidong <cyd@gnu.org>
10477 * keyboard.c (process_special_events): Handle all X selection
10478 requests in kbd_buffer, not just the next one (Bug#8869).
10480 2012-02-23 Chong Yidong <cyd@gnu.org>
10482 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
10483 call when setting menu-bar-lines and tool-bar-lines parameters.
10484 (unwind_create_frame_1): New helper function.
10486 * window.c (inhibit_window_configuration_change_hook): New var.
10487 (run_window_configuration_change_hook): Obey it.
10488 (syms_of_window): Initialize it.
10490 2012-02-22 Chong Yidong <cyd@gnu.org>
10492 * xterm.c (x_draw_image_relief): Add missing type check for
10493 Vtool_bar_button_margin (Bug#10743).
10495 2012-02-21 Chong Yidong <cyd@gnu.org>
10497 * fileio.c (Vfile_name_handler_alist): Doc fix.
10499 * buffer.c (Fget_file_buffer): Protect against invalid file
10500 handler return value.
10502 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
10504 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
10505 when computing $valmask.
10507 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
10508 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
10509 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
10510 It's useless in that case, and it can cause problems on hosts
10511 that allocate halves of EMACS_INT values separately.
10512 Reported by Dan Horák. Diagnosed by Andreas Schwab in
10513 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
10514 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
10515 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
10516 it avoids undefined behavior on hosts where shifting right by more
10517 than the word width has undefined behavior.
10519 2012-02-19 Chong Yidong <cyd@gnu.org>
10521 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
10522 (Funhandled_file_name_directory, Ffile_name_as_directory)
10523 (Fdirectory_file_name, Fexpand_file_name)
10524 (Fsubstitute_in_file_name): Protect against invalid file handler
10525 return values (Bug#10845).
10527 2012-02-18 Eli Zaretskii <eliz@gnu.org>
10529 * .gdbinit (pitx): Fix incorrect references to fields of the
10532 2012-02-17 Chong Yidong <cyd@gnu.org>

10536 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
10538 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
10539 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
10541 2012-02-15 Chong Yidong <cyd@gnu.org>
10543 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
10544 marked as special. Also, starting docstrings with * is obsolete.
10546 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
10548 * gnutls.c (emacs_gnutls_write): Fix last change.
10550 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>
10552 * gnutls.c (emacs_gnutls_write): Set errno appropriately for
10555 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
10557 * keymap.c (Fsingle_key_description): Handle char ranges.
10559 2012-02-12 Chong Yidong <cyd@gnu.org>
10561 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
10562 as that creates a dangerous corner case.
10564 * window.c (Fdelete_window_internal): Invalidate the mouse
10565 highlight (Bug#9904).
10567 2012-02-12 Glenn Morris <rgm@gnu.org>
10569 * xselect.c (Fx_own_selection_internal)
10570 (Fx_get_selection_internal, Fx_disown_selection_internal)
10571 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
10572 * nsselect.m (Fx_own_selection_internal)
10573 (Fx_disown_selection_internal, Fx_selection_exists_p)
10574 (Fx_selection_owner_p, Fx_get_selection_internal):
10575 Sync docs and argument specs with the xselect.c versions.
10577 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
10579 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
10581 2012-02-11 Eli Zaretskii <eliz@gnu.org>
10583 * w32select.c (Fx_selection_exists_p): Sync doc string and
10584 argument list with xselect.c. (Bug#10783)
10586 * w16select.c (Fx_selection_exists_p): Sync doc string and
10587 argument list with xselect.c. (Bug#10783)
10589 2012-02-10 Glenn Morris <rgm@gnu.org>
10591 * fns.c (Fsecure_hash): Doc fix.
10593 2012-02-09 Kenichi Handa <handa@m17n.org>
10595 * coding.c (produce_chars): Fix updating of src_end (Bug#10701).
10597 2012-02-07 Chong Yidong <cyd@gnu.org>
10599 * buffer.c (Fbuffer_local_variables)
10600 (buffer_lisp_local_variables): Handle unbound vars correctly;
10601 don't let Qunbound leak into Lisp.
10603 2012-02-07 Glenn Morris <rgm@gnu.org>
10605 * image.c (Fimagemagick_types): Doc fix.
10607 * image.c (imagemagick-render-type): Change it from a lisp object
10608 to an integer. Move the doc here from the lisp manual.
10609 Treat all values not equal to 0 the same.
10611 2012-02-06 Chong Yidong <cyd@gnu.org>
10613 * doc.c (store_function_docstring): Avoid applying docstring of
10614 alias to base function (Bug#2603).
10616 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>

10621 2012-02-04 Chong Yidong <cyd@gnu.org>
10623 * nsterm.m: Declare a global (Bug#10694).
10625 2012-02-04 Eli Zaretskii <eliz@gnu.org>
10627 * w32.c (get_emacs_configuration_options):
10628 Include --enable-checking, if specified, in the return value.
10630 2012-02-04 Martin Rudalics <rudalics@gmx.at>
10632 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
10633 after rounding frame sizes. (Bug#9723)
10635 2012-02-04 Eli Zaretskii <eliz@gnu.org>
10637 * keyboard.c (adjust_point_for_property): Don't position point
10638 before BEGV. (Bug#10696)
10640 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
10642 Handle overflow when computing char display width (Bug#9496).
10643 * character.c (char_width): Return EMACS_INT, not int.
10644 (char_width, c_string_width): Check for overflow when
10645 computing the width; this is possible now that individual
10646 characters can have unbounded width. Problem introduced
10647 by merge from Emacs 23 on 2012-01-19.
10649 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
10651 * dbusbind.c (Fdbus_register_method): Mention the return value
10652 :ignore in the docstring.
10654 2012-02-02 Glenn Morris <rgm@gnu.org>
10656 * callproc.c (Fcall_process, Fcall_process_region): Doc fix.
10658 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:
10659 Unconditionally set to t. (Bug#10673)

10664 2012-02-02 Kenichi Handa <handa@m17n.org>
10666 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
10667 0, do not call append_composite_glyph.
10669 2012-02-02 Kenichi Handa <handa@m17n.org>
10671 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
10673 (x_produce_glyphs): If the component of a composition is a null
10674 string, set it->pixel_width to 1 to avoid zero-width glyph.
10676 2012-02-01 Eli Zaretskii <eliz@gnu.org>
10678 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
10679 first 2 arguments are identical. This makes inserting large
10680 output from a subprocess an order of magnitude faster on
10681 MS-Windows, where all sbrk'ed memory is always contiguous.
10683 2012-01-31 Glenn Morris <rgm@gnu.org>
10685 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

11182 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
11183 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in
11184 this macro definition.
11186 * s/ms-w32.h (tzname): Redirect to _tzname for all values of

11211 * xdisp.c (redisplay_window): If cursor row is not fully visible
11212 after recentering, and scroll-conservatively is set to a large
11213 number, scroll window by a few more lines to make the cursor fully
11214 visible and out of scroll-margin. (Bug#10105)
11215 (start_display): Don't move to the next line if the display should
11216 start at a newline that is part of a display vector or an overlay
11217 string. (Bug#10119)

11297 Otherwise, valgrind does not work on some platforms.
11298 Problem reported by Andreas Schwab in
11299 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
11300 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
11301 is set, removing the need for VIRT_ADDRESS_VARIES.
11302 (PURE_P): Use a more-efficient implementation that needs just one
11303 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
11304 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
11305 to 4 (xorl, subq, cmpq, setbe).
11306 * alloc.c (pure): Always extern now, since that's the
11307 VIRT_ADDR_VARIES behavior.
11308 (PURE_POINTER_P): Use a single comparison, not two, for
11309 consistency with the new puresize.h.
11310 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
11311 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

11317 (erase_phys_cursor, update_window_cursor, show_mouse_face)
11318 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
11319 behave as if the cursor position were at the window margin.
11321 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
11322 and the cursor position is out of bounds, behave as if the cursor
11323 position were at the window margin. (Bug#10075)
11325 2011-11-18 Chong Yidong <cyd@gnu.org>
11327 * window.c (Fwindow_combination_limit): Make first argument

11346 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
11348 * xdisp.c (row_hash): New function, body extracted from
11349 compute_line_metrics.
11350 (compute_line_metrics): Call row_hash, instead of computing the
11353 * dispnew.c (verify_row_hash): Call row_hash for computing the
11354 hash code of a row, instead of duplicating code from xdisp.c.
11356 * dispextern.h (row_hash): Add prototype.
11358 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
11360 * frame.c (delete_frame): Don't delete the terminal when the last

11385 (recombine_windows, make_parent_window, make_window)
11386 (Fsplit_window_internal, saved_window)
11387 (Fset_window_configuration, save_window_save): Rename all
11388 occurrences of window_nest to window_combination_limit.
11390 2011-11-15 Juanma Barranquero <lekktu@gmail.com>

11394 2011-11-14 Eli Zaretskii <eliz@gnu.org>
11396 * xdisp.c (display_line): Move the call to
11397 highlight_trailing_whitespace before the call to
11398 compute_line_metrics, since the latter needs to see the final
11399 faces of all the glyphs to compute ROW's hash value.
11400 Fixes assertion violations in row_equal_p. (Bug#10035)
11402 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
11404 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
11405 just return (bug#10044).
11407 2011-11-12 Eli Zaretskii <eliz@gnu.org>
11409 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
11410 with user-defined heap size. Bump the default size of the temacs
11411 heap to 27MB, to avoid memory warning when running temacs.
11412 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
11414 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
11415 current_matrix and desired_matrix. (Bug#9990)
11416 (verify_row_hash) [XASSERTS]: New function.
11417 (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify
11418 that the hash value of glyph rows is correct.

11461 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
11463 Avoid some portability problems by eschewing 'extern inline' functions.
11464 The trivial performance wins aren't worth the portability hassles; see
11465 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
11467 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
11468 (window_box_width, window_box_left, window_box_left_offset)
11469 (window_box_right, window_box_right_offset): Undo previous change,
11470 by removing the "extern"s.
11471 * intervals.c (adjust_intervals_for_insertion)
11472 (adjust_intervals_for_deletion): Undo previous change,
11473 making these static again.
11474 (offset_intervals, temp_set_point_both, temp_set_point)
11475 (copy_intervals_to_string): No longer inline.
11476 * xdisp.c (window_text_bottom_y, window_box_width)

11516 This is also needed for porting to any host where GC_MARK_STACK is
11517 not GC_MAKE_GCPROS_NOOPS.
11518 (which_symbols): Use it.

11533 * xmenu.c (cleanup_widget_value_tree): New function.
11534 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
11535 calling free_menubar_widget_value_tree directly (Bug#9830).

11541 (window_box_width, window_box_left, window_box_left_offset)
11542 (window_box_right, window_box_right_offset): Declare extern.
11543 Otherwise, these inline functions do not conform to C99 and
11544 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
11545 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
11546 * intervals.c (adjust_intervals_for_insertion)
11547 (adjust_intervals_for_deletion): Now extern, because otherwise the
11548 extern inline functions 'offset_intervals' couldn't refer to it.
11549 (static_offset_intervals): Remove.
11550 (offset_intervals): Rewrite using the old contents of
11551 static_offset_intervals. The old version didn't conform to C99
11552 because an extern inline function contained a reference to an
11553 identifier with static linkage.

11575 (Fwindow_vscroll): Doc fix.
11576 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
11577 argument, since it makes no sense to pass a live window and for

11605 * nsfns.m: Declare image_cache_refcount if GLYPH_DEBUG.
11606 (unwind_create_frame): New function (Bug#9943).
11607 (Fx_create_frame): Restructure code to be more similar to the one in
11608 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).

11610 Move terminal->reference_count++ just before making the frame official
11613 * nsterm.m (x_free_frame_resources): New function.
11614 (x_destroy_window): Move code to x_free_frame_resources.
11616 * xfns.c (unwind_create_frame): Fix comment.
11617 (Fx_create_frame, x_create_tip_frame):

11699 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
11700 past the beginning of the current glyph matrix.
11702 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
11704 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.

11750 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
11751 Not clear what it was for, and it causes various bugs. (Bug#9839)
11753 2011-10-28 Eli Zaretskii <eliz@gnu.org>
11755 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a

11775 2011-10-28 Eli Zaretskii <eliz@gnu.org>
11777 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
11778 <oslsachem@gmail.com> for helping to debug this.
11780 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)

11786 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
11788 (w32font_open_internal, compute_metrics):
11789 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
11790 instead of calling the "wide" APIs directly.
11792 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
11794 * w32.h (syms_of_w32font): Add prototype.
11796 2011-10-27 Juanma Barranquero <lekktu@gmail.com>

11800 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
11801 (Fmove_to_window_line): Doc fix.
11803 2011-10-27 Chong Yidong <cyd@gnu.org>
11805 * process.c (make_process): Set gnutls_state to NULL.
11807 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
11808 non-NULL, regardless of GNUTLS_INITSTAGE.
11809 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
11810 an error. Set process slots as soon as we allocate them.

11836 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
11838 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
11840 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
11842 * keyboard.c (test_undefined): New function (bug#9751).
11843 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
11845 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
11847 * sysdep.c (init_sys_modes): Fix the check for the controlling
11848 terminal (Bug#6649).
11850 2011-10-20 Eli Zaretskii <eliz@gnu.org>
11852 * dispextern.h (struct bidi_it): New member next_en_type.
11854 * bidi.c (bidi_line_init): Initialize the next_en_type member.
11855 (bidi_resolve_explicit_1): When next_en_pos is valid for the
11856 current character, check also for next_en_type being WEAK_EN.
11857 (bidi_resolve_weak): Don't enter the expensive loop if the current
11858 position is before next_en_pos. Record the bidi type of the first
11859 non-ET, non-BN character we find, in addition to its position.
11860 (bidi_level_of_next_char): Invalidate next_en_type when
11861 next_en_pos is over-stepped.
11863 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
11865 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
11866 * editfns.c: Rewrite current-time-zone so that it invokes
11867 the equivalent of (format-time-string "%Z") to get the time zone name.
11868 This fixes a bug when the time zone name contains characters that
11869 need converting from the system time locale to Emacs internal format.
11870 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
11871 that patch fixed format-time-string to do the conversion, but
11872 I forgot to fix current-time-zone.
11873 (format_time_string): New function, containing most of
11874 what Fformat_time_string used to contain.
11875 (Fformat_time_string): Rewrite in terms of format_time_string.
11876 This doesn't change this function's behavior.
11877 (current-time-zone): Rewrite to use format_time_string.
11878 This fixes the bug reported by Michael Schierl in
11879 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
11880 Jason Rumney's 2007-06-07 change worked around this bug, but
11882 * systime.h (tzname, timezone): Remove no-longer-used declarations.
11884 2011-10-19 Eli Zaretskii <eliz@gnu.org>
11886 * xdisp.c (start_display): If the character at POS is displayed
11887 via a display vector, reset IT->current.dpvec_index to zero.
11888 (try_window_reusing_current_matrix): If a line ends in a display
11889 vector or the next line starts in a display vector, continue
11890 redrawing the window even though the character position of
11891 start_row was reached.
11894 2011-10-18 Chong Yidong <cyd@gnu.org>
11896 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
11897 with nobreak-char-display too.
11899 2011-10-18 Eli Zaretskii <eliz@gnu.org>
11901 Fix part 3 of bug#9771.
11902 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
11903 (bidi_resolve_neutral): Don't enter the expensive loop looking for
11904 non-neutral characters if the current character is a paragraph
11905 separator (a.k.a. Newline). This avoids running the same
11906 expensive loop twice, once when we consume the preceding newline
11907 and the other time when the line actually needs to be displayed.
11908 Avoid the loop when we see neutrals on the base embedding level
11909 following a character whose directionality is the same as the
11910 paragraph's. This avoids running the expensive loop when a line
11911 ends in a long sequence of neutrals, like control characters.
11912 Add assertion against STRONG_AL type. Slightly rearrange code
11913 that determines the type of a neutral given the first non-neutral
11915 (bidi_level_of_next_char): Set next_en_pos to zero when
11916 invalidating its info.
11918 2011-10-17 Eli Zaretskii <eliz@gnu.org>
11920 * xdisp.c (push_display_prop): Determine whether to record string
11921 or buffer position by IT->string, not by IT->method. Allow
11922 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
11923 (move_it_vertically_backward): Don't look for character position
11924 immediately after the newline when in a continuation line.
11927 2011-10-15 Martin Rudalics <rudalics@gmx.at>
11929 * window.c (coordinates_in_window): Rewrite and delabelize
11930 vertical border check. (Bug#5357) (Bug#9618)
11932 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
11934 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
11935 errors in XSetWindowBorder (bug#9310).
11937 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
11939 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
11940 avoid crash when xmalloc overrun checking is enabled.
11942 2011-10-13 Eli Zaretskii <eliz@gnu.org>
11944 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
11945 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
11946 cursor motion with <left> and <right> arrow keys.
11948 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
11949 some callers set that themselves.
11951 2011-10-12 Eli Zaretskii <eliz@gnu.org>
11953 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
11954 display string and the previous row comes from the same string and
11955 is empty. (Bug#9739) (Bug#9738)
11957 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
11959 * doc.c (get_doc_string): Encode file name (bug#9735).
11961 2011-10-12 Eli Zaretskii <eliz@gnu.org>
11963 * bidi.c (bidi_level_of_next_char):
11964 * xdisp.c (get_visually_first_element): Remove old incorrect
11965 comments regarding the Unicode Line Separator character.
11967 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
11969 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
11971 * alloc.c (Fgc_status): Do not access beyond zombies array
11972 boundary if nzombies > MAX_ZOMBIES.
11973 * alloc.c (dump_zombies): Add missing format specifier.
11975 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
11977 * xdisp.c (set_cursor_from_row): Simplify conditionals,
11978 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
11980 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
11981 Some packages use them to denote characters with modifiers.
11983 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
11985 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
11986 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
11987 matching a pp-number. Rename parameter var to var1.
11989 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
11991 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
11993 2011-10-08 Glenn Morris <rgm@gnu.org>
11995 * callint.c (Fcall_interactively): Give a more explicit error for the
11996 'c' case with a non-character input. (Bug#8479)
11998 2011-10-08 Eli Zaretskii <eliz@gnu.org>
12000 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
12002 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
12003 lines that are hscrolled on the left.
12005 * dispnew.c (buffer_posn_from_coords): Account for a possible
12006 presence of header-line. (Bug#4426)
12008 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
12010 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
12011 Don't advertise functionality which we discourage or doesn't work.
12013 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
12015 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
12016 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
12017 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
12018 this makes Emacs dump core during garbage collection on rare
12019 occasions. sizeof is obviously inferior to offsetof here, so
12020 stick with offsetof.
12021 (GC_POINTER_ALIGNMENT): New macro.
12022 (mark_memory): Omit 3rd (offset) arg; caller changed.
12023 Don't assume EMACS_INT alignment is the same as pointer alignment.
12025 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
12027 * keyboard.c (read_key_sequence_remapped): New var.
12028 (read_key_sequence): Compute remapping in the right buffer.
12029 (command_loop_1): Use read_key_sequence's remapping directly.
12031 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
12033 * dired.c (file_name_completion): Don't expand file name.
12034 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
12035 before checking file name handler.
12037 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
12038 they've been requested explicitly (bug#9591).
12040 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
12042 * keymap.c (Fsingle_key_description): Use make_specified_string
12043 instead of build_string to build string from push_key_description.
12046 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
12048 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
12049 This fixes a Y2038 bug on 64-bit hosts.
12050 * buffer.c (reset_buffer):
12051 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
12052 (Fclear_buffer_auto_save_failure):
12053 Use 0, not -1, to represent an unset failure time, since time_t
12054 might not be signed.
12056 Remove dependency on glibc malloc internals.
12057 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12058 Move back here from lisp.h, but with their new implementations.
12059 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
12060 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
12061 * charset.c (charset_table_init): New static var.
12062 (syms_of_charset): Use it instead of xmalloc. This removes a
12063 dependency on glibc malloc internals. See Eli Zaretskii's comment in
12064 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
12065 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12066 Move back to alloc.c.
12067 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
12068 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
12070 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
12072 * nsterm.m (windowDidResize): Call x_set_window_size only when
12073 ns_in_resize is true. Otherwise set pixelwidth/height and
12074 call change_frame_size (Bug#9628).
12076 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
12078 Port --enable-checking=all to Fedora 14 x86-64.
12079 * charset.c (syms_of_charset): Also account for glibc malloc's
12080 internal overhead when calculating the initial malloc maximum.
12082 Port --enable-checking=all to Fedora 14 x86.
12083 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12085 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
12086 (overrun_check_realloc, overrun_check_free):
12087 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
12088 That way, xmalloc returns a properly-aligned pointer even if
12089 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
12090 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
12091 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
12092 into account when calculating the initial malloc maximum.
12093 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12094 Move here from alloc.c, so that charset.c can use it too.
12095 Properly align; the old code wasn't right for common 32-bit hosts
12096 when configured with --enable-checking=all.
12097 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
12098 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
12100 2011-09-29 Eli Zaretskii <eliz@gnu.org>
12102 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
12105 2011-09-28 Eli Zaretskii <eliz@gnu.org>
12107 * xdisp.c (compute_display_string_end): If there's no display
12108 string at CHARPOS, return -1.
12110 * bidi.c (bidi_fetch_char): When compute_display_string_end
12111 returns a negative value, treat the character as a normal
12112 character not covered by a display string. (Bug#9624)
12114 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
12116 * lread.c (Fread_from_string): Fix typo in docstring.
12118 2011-09-27 Eli Zaretskii <eliz@gnu.org>
12120 * xdisp.c (handle_invisible_prop): If invisible text ends on a
12121 newline, reseat the iterator instead of bidi-iterating there one
12122 character at a time. (Bug#9610)
12123 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
12124 TO_CHARPOS if the bidi iterator is at base embedding level.
12126 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
12128 * lread.c (readevalloop): Use correct code for NBSP.
12129 (read1): Likewise. (Bug#9608)
12131 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
12133 * dbusbind.c (Fdbus_register_signal): When service is not
12134 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
12136 2011-09-25 Glenn Morris <rgm@gnu.org>
12138 * buffer.c (truncate-lines): Doc fix.
12140 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
12142 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
12143 (Fset_window_next_buffers): Doc fix.
12145 2011-09-24 Glenn Morris <rgm@gnu.org>
12147 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
12149 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
12151 Fix minor problems found by static checking.
12152 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
12153 * indent.c (Fvertical_motion): Fix == vs = typo.
12155 2011-09-24 Eli Zaretskii <eliz@gnu.org>
12157 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
12158 Default value is now t. Doc fix.
12160 * indent.c (Fvertical_motion): Compute and apply the overshoot
12161 logic when moving up, not only when moving down. Fix the
12162 confusing name and values of the it_overshoot_expected variable;
12163 logic changes accordingly. (Bug#9254) (Bug#9549)
12165 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
12166 CHARPOS is covered by a display string which includes newlines.
12167 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
12168 is covered by a display string with embedded newlines.
12170 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
12172 * dbusbind.c (Fdbus_register_signal): Add match rule to
12173 Vdbus_registered_objects_table. (Bug#9581)
12174 (Fdbus_register_method, Vdbus_registered_objects_table):
12177 2011-09-24 Jim Meyering <meyering@redhat.com>
12179 do not ignore write error for any output size
12180 The previous change was incomplete.
12181 While it makes emacs --batch detect the vast majority of stdout
12182 write failures, errors were still ignored whenever the output size is
12183 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
12184 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
12185 && echo FAIL: ignored write error
12186 FAIL: ignored write error
12187 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
12188 && echo FAIL: ignored write error
12189 FAIL: ignored write error
12190 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
12192 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
12194 * emacs.c (Fkill_emacs): In noninteractive mode exit
12195 non-successfully if a write error occurred on stdout. (Bug#9574)
12197 2011-09-21 Eli Zaretskii <eliz@gnu.org>
12199 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
12202 * dispextern.h (struct it): Update the comment documenting what
12205 2011-09-20 Eli Zaretskii <eliz@gnu.org>
12207 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
12208 a display string, extend search for cursor position to end of row.
12209 (find_row_edges): If the row ends in a newline from a display
12210 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
12211 Handle the case of a display string with multiple newlines.
12212 (Fcurrent_bidi_paragraph_direction): Fix search for previous
12213 non-empty line. Fixes confusing cursor motion with arrow keys at
12214 the beginning of a line that starts with whitespace.
12216 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
12218 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
12221 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
12223 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
12224 boolean (Bug#9154).
12226 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12228 * xdisp.c (display_line): Record maximum and minimum buffer
12229 positions even if no glyphs were produced (e.g., by a zero-width
12230 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
12231 buffer positions that will be removed from the glyph row because
12233 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
12234 column is beyond frame width: don't subtract 1 "pixel" when
12235 computing width of the stretch.
12236 (reseat_at_next_visible_line_start): Undo the change made on
12237 2011-09-17 that saved paragraph information and restored it after
12238 the call to `reseat'. (Bug#9545)
12240 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12242 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
12243 and turn window cursor on if cleared (Bug#9415).
12245 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
12247 * search.c (boyer_moore): Take unibyte characters from pattern
12248 literally. (Bug#9458)
12250 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12252 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
12254 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
12256 Fix minor problem found by static checking.
12257 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
12258 initialized, to pacify gcc -Wuninitialized.
12260 * fileio.c: Report proper errno when syscall falls.
12261 (Finsert_file_contents): Save and restore errno,
12262 so that report_file_error outputs the correct diagnostic.
12263 (Fwrite_region) [CLASH_DETECTION]: Likewise.
12265 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12267 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
12269 2011-09-17 Eli Zaretskii <eliz@gnu.org>
12271 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
12272 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
12274 2011-09-17 Eli Zaretskii <eliz@gnu.org>
12276 * xdisp.c (reseat_at_next_visible_line_start): Keep information
12277 about the current paragraph and restore it after the call to reseat.
12279 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
12280 (bidi_find_paragraph_start): Search back for paragraph beginning
12281 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
12282 (bidi_move_to_visually_next): Only trigger paragraph-related
12283 computations when the last character is a newline or at EOB, not
12284 just any NEUTRAL_B. (Bug#9470)
12286 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
12287 truncated lines if point is covered by a display string. (Bug#9524)
12289 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
12291 * xselect.c: Relax test for outgoing X longs (Bug#9498).
12292 (cons_to_x_long): New function.
12293 (lisp_data_to_selection_data): Use it. Correct the test for
12294 short-versus-long data; it was negated. Break out of vector
12295 loop, for efficiency, when a long datum is discovered.
12297 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
12299 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
12301 2011-09-16 Eli Zaretskii <eliz@gnu.org>
12303 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
12304 GCC PR/17406) by declaring this function with external scope.
12306 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
12308 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
12309 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
12311 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
12313 * editfns.c (Fformat): Correctly handle text properties on "%%".

12319 * term.c (encode_terminal_code):
12320 * composite.c (composition_update_it, get_composition_id):
12321 * xdisp.c (get_next_display_element)
12322 (fill_composite_glyph_string): Add comments about special meaning
12323 of TAB characters in a composition.
12325 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
12327 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
12328 This occurs when processing a multibyte format.
12329 Problem reported by Wolfgang Jenker.
12331 2011-09-15 Johan Bockgård <bojohan@gnu.org>
12333 * xdisp.c (try_cursor_movement): Only check for exact match if
12334 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
12336 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
12338 Remove unused external symbols.
12339 * dispextern.h (calc_pixel_width_or_height): Remove decl.
12340 * xdisp.c (calc_pixel_width_or_height): Now static.
12341 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
12342 * indent.c (check_display_width):
12343 * w32term.c: Fix comment to match code.
12344 * xterm.c, xterm.h (x_catching_errors): Remove.
12346 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
12348 * xselect.c: Use signed conversions more consistently (Bug#9498).
12349 (selection_data_to_lisp_data): Assume incoming selection data are
12350 signed integers, not unsigned. This is to be consistent with
12351 outgoing selection data, which was modified to use signed integers
12352 in as part of the fix to Bug#9196 in response to Jan D.'s comment
12353 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
12354 expects long, not unsigned long.
12356 2011-09-14 Eli Zaretskii <eliz@gnu.org>
12358 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
12359 computation of loop end. Reported by Johan Bockgård
12362 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
12364 * frame.c (Fother_visible_frames_p): Function deleted.
12366 2011-09-12 Eli Zaretskii <eliz@gnu.org>
12368 * indent.c (compute_motion): Process display vector front to back
12369 rather than the other way around. (Bug#2496)
12371 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
12373 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
12375 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
12377 * minibuf.c (Fread_from_minibuffer): Doc fix.
12379 2011-09-11 Eli Zaretskii <eliz@gnu.org>
12381 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
12382 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
12384 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
12386 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
12387 value for non-existent files.
12389 2011-09-11 Eli Zaretskii <eliz@gnu.org>
12391 * fileio.c (Finsert_file_contents): If the file cannot be opened,
12392 set its "size" to -1. This will set the modtime_size field of
12393 the corresponding buffer to -1, which is what
12394 verify-visited-file-modtime expects for files that do not exist.
12397 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
12399 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
12401 * lisp.h: ... from here. push_key_description is no longer
12402 defined in keyboard.c, so its declaration should not be in
12403 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
12404 logically belongs with push_key_description.
12406 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
12408 * buffer.h: Include <sys/types.h> instead of <time.h>.
12409 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
12410 Problem reported by Herbert J. Skuhra.
12412 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
12414 * xml.c (parse_region): Make the parsing work for
12415 non-comment-starting XML files again (bug#9144).
12417 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
12419 * image.c (gif_load): Fix calculation of bottom and right corner.
12422 2011-09-10 Eli Zaretskii <eliz@gnu.org>
12424 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
12425 redisplay in small windows.
12427 2011-09-09 Eli Zaretskii <eliz@gnu.org>
12429 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
12431 2011-09-08 Martin Rudalics <rudalics@gmx.at>
12433 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
12434 Operate on live windows only.
12436 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
12438 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
12440 2011-09-07 Eli Zaretskii <eliz@gnu.org>
12442 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
12443 only under bidi iteration.
12445 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
12447 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
12449 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12451 isnan: Fix porting problem to Solaris 10 with bundled gcc.
12452 Without this fix, the command to link temacs failed due to an
12453 undefined symbol __builtin_isnan. This is because
12454 /usr/include/iso/math_c99.h #defines isnan(x) to
12455 __builtin_isnan(x), but the bundled gcc, which identifies itself
12456 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
12458 * floatfns.c (isnan): #undef, and then #define to a clone of
12460 (Fisnan): Always define, since it's always available now.
12461 (syms_of_floatfns): Always define isnan at the Lisp level.
12463 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12465 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
12467 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12469 * fileio.c: Fix bugs with large file offsets (Bug#9428).
12470 The previous code assumed that file offsets (off_t values) fit in
12471 EMACS_INT variables, which is not true on typical 32-bit hosts.
12472 The code messed up by falsely reporting buffer overflow in cases
12473 such as (insert-file-contents "big" nil 1 2) into an empty buffer
12474 when "big" contains more than 2**29 bytes, even though this
12475 inserts just one byte and does not overflow the buffer.
12476 (Finsert_file_contents): Store file offsets as off_t
12477 values, not as EMACS_INT values. Check for overflow when
12478 converting between EMACS_INT and off_t. When checking for
12479 buffer overflow or for overlap, take the offsets into account.
12480 Don't use EMACS_INT for small values where int suffices.
12481 When checking for overlap, fix a typo: ZV was used where
12482 ZV_BYTE was intended.
12483 (Fwrite_region): Don't assume off_t fits into 'long'.
12484 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
12486 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
12488 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
12490 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
12492 sprintf-related integer and memory overflow issues (Bug#9412).
12494 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
12495 (esprintf, exprintf, evxprintf): New functions.
12496 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
12497 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
12498 (modify_event_symbol): Do not assume that the length of
12499 name_alist_or_stem is safe to alloca and fits in int.
12500 (Fexecute_extended_command): Likewise for function name and binding.
12501 (Frecursion_depth): Wrap around reliably on integer overflow.
12502 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
12503 since some callers pass EMACS_INT values.
12504 (Fsingle_key_description): Don't crash if symbol name contains more
12505 than MAX_ALLOCA bytes.
12506 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
12507 (get_minibuffer): Arg is now EMACS_INT, not int.
12508 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
12509 (esprintf, exprintf, evxprintf): New decls.
12510 * window.h (command_loop_level, minibuf_level): Reflect API changes.
12512 * dbusbind.c (signature_cat): New function.
12513 (xd_signature, Fdbus_register_signal):
12514 Do not overrun buffer; instead, report string overflow.
12516 * dispnew.c (add_window_display_history): Don't overrun buffer.
12517 Truncate instead; this is OK since it's just a log.
12519 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
12520 even if the time zone offset is outlandishly large.
12521 Don't mishandle offset == INT_MIN.
12523 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
12524 when creating daemon; the previous buffer-overflow check was incorrect.
12526 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
12527 which has the guts of the old verror function.
12529 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
12530 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
12532 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
12533 (font_unparse_xlfd): Don't blindly alloca long strings.
12534 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
12535 fits in int, when using sprintf. Use single snprintf to count
12536 length of string rather than counting it via multiple sprintfs;
12537 that's simpler and more reliable.
12538 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
12539 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
12540 sprintf, in case result does not fit in int.
12542 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
12543 (fontset_from_font): Print it.
12545 * frame.c (tty_frame_count): Now printmax_t, not int.
12546 (make_terminal_frame, set_term_frame_name): Print it.
12547 (x_report_frame_params): In X, window IDs are unsigned long,
12548 not signed long, so print them as unsigned.
12549 (validate_x_resource_name): Check for implausibly long names,
12550 and don't assume name length fits in 'int'.
12551 (x_get_resource_string): Don't blindly alloca invocation name;
12552 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
12555 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
12556 (xg_check_special_colors, xg_set_geometry):
12557 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
12559 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
12560 Use esprintf, not sprintf, in case result does not fit in int.
12562 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
12563 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
12564 it as a large positive number.
12565 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
12566 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
12568 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
12569 in case result does not fit in int.
12571 * print.c (float_to_string): Detect width overflow more reliably.
12572 (print_object): Make sprintf buffer a bit bigger, to avoid potential
12573 buffer overrun. Don't assume list length fits in 'int'. Treat
12574 print length of 0 as 0, not as infinity; to be consistent with other
12575 uses of print length in this function. Don't overflow print length
12576 index. Don't assume hash table size fits in 'long', or that
12577 vectorlike size fits in 'unsigned long'.
12579 * process.c (make_process): Use printmax_t, not int, to format
12580 process-name gensyms.
12582 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
12584 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
12585 to avoid potential buffer overrun.
12587 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
12588 if X resource line is longer than 512 bytes.
12590 * xfns.c (x_window): Make sprintf buffer a bit bigger
12591 to avoid potential buffer overrun.
12593 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
12595 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
12597 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
12599 Integer overflow fixes for scrolling, etc.
12600 Without these, Emacs silently mishandles large integers sometimes.
12601 For example, "C-u 4294967297 M-x recenter" was treated as if
12602 it were "C-u 1 M-x recenter" on a typical 64-bit host.
12604 * xdisp.c (try_window_id): Check Emacs fixnum range before
12605 converting to 'int'.
12607 * window.c (window_scroll_line_based, Frecenter):
12608 Check that an Emacs fixnum is in range before assigning it to 'int'.
12609 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
12610 values converted from Emacs fixnums.
12611 (Frecenter): Don't wrap around a line count if it is out of 'int'
12612 range; instead, treat it as an extreme value.
12613 (Fset_window_configuration, compare_window_configurations):
12614 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
12616 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
12617 that can exceed INT_MAX. Check that EMACS_INT value is in range
12618 before assigning it to the (possibly-narrower) index.
12619 (match_limit): Don't assume that a fixnum can fit in 'int'.
12621 * print.c (print_object): Use ptrdiff_t, not int, for index that can
12624 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
12625 (Fvertical_motion): Don't wrap around LINES values that don't fit
12626 in 'int'. Instead, treat them as extreme values. This is good
12627 enough for windows, which can't have more than INT_MAX lines anyway.
12629 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
12631 * Require libxml/parser.h to avoid compilation warning.
12633 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
12635 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
12636 since this reportedly can destroy thread storage.
12638 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
12640 * syntax.c (find_defun_start): Update all cache variables if
12641 exiting early (Bug#9401).
12643 2011-08-30 Eli Zaretskii <eliz@gnu.org>
12645 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
12647 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
12648 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
12649 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
12651 * term.c (tty_append_glyph): New function.
12652 (produce_stretch_glyph): Static function and its prototype deleted.
12654 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
12657 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
12659 * image.c (parse_image_spec): Check for nonnegative, not for positive,
12660 when checking :margin (Bug#9390).
12661 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
12662 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
12663 so that the name doesn't mislead. All uses changed.
12665 2011-08-28 Johan Bockgård <bojohan@gnu.org>
12667 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
12670 2011-08-27 Eli Zaretskii <eliz@gnu.org>
12672 * xdisp.c (move_it_to): Don't bail out early when reaching
12673 position beyond to_charpos, if we are scanning backwards.
12674 (move_it_vertically_backward): When DY == 0, make sure we get to
12675 the first character in the line after the newline.
12677 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
12679 * ccl.c: Improve and simplify overflow checking (Bug#9196).
12680 (ccl_driver): Do not generate an out-of-range pointer.
12681 (Fccl_execute_on_string): Remove unnecessary check for
12682 integer overflow, noted by Stefan Monnier in
12683 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
12684 Remove a FIXME that didn't need fixing.
12685 Simplify the newly-introduced buffer reallocation code.
12687 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
12689 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
12691 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
12693 Integer and memory overflow issues (Bug#9196).
12695 * doc.c (get_doc_string): Rework so that
12696 get_doc_string_buffer_size is the actual buffer size, rather than
12697 being 1 less than the actual buffer size; this makes xpalloc more
12700 * image.c (x_allocate_bitmap_record, cache_image):
12701 * xselect.c (Fx_register_dnd_atom):
12702 Simplify previous changes by using xpalloc.
12704 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
12705 since either will do and ptrdiff_t is convenient with xpalloc.
12707 * charset.c (charset_table_size)
12708 (struct charset_sort_data.priority): Now ptrdiff_t.
12709 (charset_compare): Don't overflow if priorities differ greatly.
12710 (Fsort_charsets): Don't assume list length fits in int.
12711 Check for size-calculation overflow when allocating sort data.
12712 (syms_of_charset): Allocate an initial charset table that is
12713 just under 64 KiB, to avoid problems with glibc malloc and mmap.
12715 * cmds.c (internal_self_insert): Check for size-calculation overflow.
12717 * composite.h (struct composition.glyph_len): Now int, not unsigned.
12718 The actual value is always <= INT_MAX, and leaving it unsigned made
12719 overflow checking harder.
12721 * dispextern.h (struct glyph_matrix.rows_allocated)
12722 (struct face_cache.size): Now ptrdiff_t, for convenience in use
12723 with xpalloc. The values are still always <= INT_MAX.
12725 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
12727 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
12728 (SAFE_NALLOCA): New macro.
12730 * region-cache.c (struct boundary.pos, find_cache_boundary)
12731 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
12732 (set_cache_region, invalidate_region_cache)
12733 (revalidate_region_cache, know_region_cache, region_cache_forward)
12734 (region_cache_backward, pp_cache):
12735 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
12736 so that ptrdiff_t * can be passed to xpalloc.
12737 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
12738 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
12739 (pp_cache): Don't assume cache_len fits in int.
12740 * region-cache.h: Adjust extern decls to match.
12742 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
12743 EMACS_INT, since either will do, for xpalloc.
12745 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
12746 (xnmalloc, xnrealloc, xpalloc): New functions.
12748 * bidi.c (bidi_shelve_header_size): New constant.
12749 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
12750 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
12752 * bidi.c (bidi_cache_shrink):
12753 * buffer.c (overlays_at, overlays_in, record_overlay_string)
12755 Don't update size of array until after memory allocation succeeds,
12756 because xmalloc/xrealloc may not return.
12757 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
12758 now that we have proper integer overflow checking.
12759 (record_overlay_string, overlay_strings): Catch overflows when
12760 calculating size of overlay_str_buf.
12762 * callproc.c (Fcall_process): Check for size overflow when
12763 calculating size of args2.
12764 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
12765 Normally we prefer signed values, but sticking with ptrdiff_t would
12766 require adding more-complicated checks.
12768 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
12769 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
12770 Redo buffer-overflow calculations to avoid integer overflow.
12771 Add a FIXME comment where memory seems to be over-allocated.
12773 * character.c (Fstring): Check for size-calculation overflow.
12775 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
12776 unnecessary integer overflow. Check for size overflow.
12777 (encode_coding_object): Don't update size until xmalloc succeeds.
12779 * composite.c (get_composition_id): Check for overflow in glyph
12780 length calculations.
12782 Integer and memory overflow fixes for display code.
12783 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
12784 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
12785 (scrolling_window): Check for overflow in size calculations.

12797 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
12798 (get_doc_string): Check for size calculation overflow.
12799 Don't update size until allocation succeeds.
12800 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
12801 EMACS_INT, where ptrdiff_t will do.
12802 (Fsubstitute_command_keys): Check for string overflow.
12804 * editfns.c (set_time_zone_rule): Don't assume environment length
12806 (message_length): Now ptrdiff_t, not int.
12807 (Fmessage_box): Don't update size until allocation succeeds.
12808 Don't assume message length fits in int.
12809 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
12811 * emacs.c (main): Do not reallocate argv, since there is a null at
12812 the end that can be overwritten, and this way there's no need to
12813 worry about size-calculation overflow.
12814 (sort_args): Check for size-calculation overflow.
12816 * eval.c (init_eval_once, grow_specpdl): Don't update size until
12818 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
12820 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
12821 (x_set_scroll_bar_width, x_figure_window_size):
12822 Check for integer overflow.
12823 (x_set_alpha): Do not assume XINT fits in int.
12825 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
12826 This is for the members text_lines, text_cols, total_lines, total_cols,
12827 where the system imposes an 'int' limit.
12829 * fringe.c (Fdefine_fringe_bitmap):
12830 Don't update size until alloc works.
12832 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
12833 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
12835 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
12836 Check for size-calculation overflow.
12837 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
12838 do, as we prefer signed integers.
12839 (id_to_widget.max_size, id_to_widget.used)
12840 (xg_store_widget_in_map, xg_remove_widget_from_map)
12841 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
12842 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
12843 Use and return ptrdiff_t, not int.
12844 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
12845 * gtkutil.h: Change prototypes to match the above.
12847 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
12848 are duplicate now that they've been promoted to lisp.h.
12849 (x_allocate_bitmap_record, x_alloc_image_color)
12850 (make_image_cache, cache_image, xpm_load):
12851 Don't update size until alloc is done.

12861 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
12862 Use ptrdiff_t, not int, to count maps.
12863 (read_char_minibuf_menu_prompt): Check for overflow in size
12864 calculations. Don't update size until allocation succeeds.
12865 Redo calculations to avoid overflow.
12866 * keyboard.h: Change prototypes to match the above.
12868 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,

12894 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
12895 for command line length. Do not attempt to address one before the
12896 beginning of an array, as that's not portable.
12898 * term.c (max_frame_lines): Remove; unused.
12899 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
12901 (encode_terminal_code, calculate_costs): Check for size
12902 calculation overflow.

12924 Use ptrdiff_t, not int, for sizes.
12925 (Finternal_make_lisp_face, cache_face):
12926 Check for size calculation overflow.
12927 (cache_face): Treat size calculation overflows as if they were
12928 memory exhaustion (the usual treatment), rather than aborting.
12930 * xfns.c (x_encode_text, x_set_name_internal)
12931 (Fx_change_window_property): Use ptrdiff_t, not int, to count
12932 sizes, since they can exceed INT_MAX in size. Check for size
12933 calculation overflow.
12935 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
12936 (xg_select): Check for size calculation overflow.
12937 Don't update size until alloc done.
12939 * xrdb.c (get_environ_db): Don't assume path length fits in int,
12940 as sprintf is limited to int lengths.
12942 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
12943 (X_LONG_MIN): New macros.
12944 Use them to make the following changes clearer.
12945 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
12946 This change doesn't affect the value now, but it may help remind
12947 future maintainers not to raise the value too much later.
12948 (SELECTION_QUANTUM): Remove, replacing with ...
12949 (selection_quantum): ... new function, which avoids overflow.
12951 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
12952 assumption that selection length fits in 'int'.
12953 (x_reply_selection_request, x_handle_selection_request)
12954 (x_get_window_property, receive_incremental_selection)

12958 (x_reply_selection_request, x_get_window_property)
12959 (receive_incremental_selection, x_property_data_to_lisp):
12960 Redo calculations to avoid overflow.
12961 (x_reply_selection_request): When sending hint, ceiling it at
12962 X_LONG_MAX rather than relying on wraparound overflow to send
12964 (x_get_window_property, receive_incremental_selection)
12965 (lisp_data_to_selection_data, x_property_data_to_lisp):
12966 Check for size-calculation overflow.
12967 (x_get_window_property, receive_incremental_selection)
12968 (lisp_data_to_selection_data, Fx_register_dnd_atom):
12969 Don't store size until memory allocation succeeds.
12970 (x_get_window_property): Plug memory leak on memory exhaustion.
12971 Don't double-block input; malloc is safe here. Don't assume 2**34
12972 - 4 fits in unsigned long. Add an xassert to check
12973 XGetWindowProperty overflow. Be more careful about overflow
12974 calculations, and distinguish size from memory overflow better.
12975 (receive_incremental_selection): When tracing, don't assume
12976 unsigned int is less than INT_MAX.
12977 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
12978 harmful) conversions of unsigned short to int.
12979 (lisp_data_to_selection_data): Don't assume that integers
12980 in the range -65535 through -1 fit in an X unsigned short.
12981 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
12982 result parameters unless successful. Rely on cons_to_unsigned
12983 to report problems with elements; the old code wasn't right anyway.
12984 (x_check_property_data): Check for int overflow; we cannot use
12985 a wider type due to X limits.
12986 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
12988 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
12990 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
12991 (x_term_init): Check for size calculation overflow.
12992 (x_color_cells): Don't store size until memory allocation succeeds.
12993 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
12994 Don't assume alloca size is less than MAX_ALLOCA.
12995 (x_term_init): Don't assume length fits in int (sprintf is limited
12998 Use ptrdiff_t for composition IDs.
12999 * character.c (lisp_string_width):
13000 * composite.c (composition_table_size, n_compositions)
13001 (get_composition_id, composition_gstring_from_id):

13017 * image.c (xpm_get_color_table_h):
13018 * lisp.h (hash_lookup, hash_put):
13019 * minibuf.c (Ftest_completion):
13020 Use ptrdiff_t for hash table indexes, not int (which is too
13021 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
13022 32-bit --with-wide-int hosts).
13024 * charset.c (Fdefine_charset_internal): Check for integer overflow.
13025 Add a FIXME comment about memory leaks.
13026 (syms_of_charset): Don't assume xmalloc returns.
13028 Don't assume that stated character widths fit in int.
13029 * character.c (Fchar_width, c_string_width, lisp_string_width):
13030 * character.h (CHAR_WIDTH):
13031 * indent.c (MULTIBYTE_BYTES_WIDTH):
13032 Use sanitize_char_width to avoid undefined and/or bad behavior
13033 with outlandish widths.
13034 * character.h (sanitize_tab_width): Rename from sanitize_width,
13035 now that we have two such functions. All uses changed.
13036 (sanitize_char_width): New inline function.
13038 Don't assume that tab-width fits in int.
13039 * character.h (sanitize_width): New inline function.
13040 (SANE_TAB_WIDTH): New macro.
13041 (ASCII_CHAR_WIDTH): Use it.
13042 * indent.c (sane_tab_width): Remove. All uses replaced by

13046 * fileio.c: Integer overflow issues with file modes.
13047 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
13049 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
13050 Remove unreachable code.
13051 (read_hex, load_charset_map_from_file): Check for integer overflow.
13053 * xterm.c: Don't go over XClientMessageEvent limit.
13054 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
13055 (x_send_scroll_bar_event): Likewise. Check that the size does not
13056 exceed limits imposed by XClientMessageEvent, as well as the usual
13057 ptrdiff_t and size_t limits.
13059 * keyboard.c: Overflow, signedness and related fixes.
13060 (make_lispy_movement): Use same integer type in forward decl
13061 that is used in the definition.
13062 (read_key_sequence, keyremap_step):
13063 Change bufsize argument back to int, undoing my 2011-03-30 change.
13064 We prefer signed types, and int is wide enough here.
13065 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
13066 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
13067 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
13068 length, not size_t. Use ptrdiff_t for index, not int.
13069 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
13070 possibility of integer overflow.
13072 Overflow, signedness and related fixes for images.
13074 * dispextern.h (struct it.stack[0].u.image.image_id)
13075 (struct_it.image_id, struct image.id, struct image_cache.size)

13082 * xdisp.c (calc_pixel_width_or_height):
13083 * xfns.c (image_cache_refcount):
13084 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
13085 on typical 64-bit hosts.

13093 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
13094 (lookup_image): Remove unnecessary tests.
13095 (xbm_image_p): Locals are now of int, not EMACS_INT,
13096 since parse_image_check makes sure they fit into int.
13097 (png_load, gif_load, svg_load_image):
13098 Prefer int to unsigned where either will do.
13099 (tiff_handler): New function, combining the cores of the
13100 old tiff_error_handler and tiff_warning_handler.
13101 This function is rewritten to use vsnprintf and thereby avoid
13102 stack buffer overflows. It uses only the features of vsnprintf
13103 that are common to both POSIX and native Microsoft.
13104 (tiff_error_handler, tiff_warning_handler): Use it.
13105 (tiff_load, gif_load, imagemagick_load_image):
13106 Don't assume :index value fits in 'int'.
13107 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
13108 (imagemagick_load_image): Check that crop parameters fit into
13109 the integer types that MagickCropImage accepts. Don't assume
13110 Vimagemagick_render_type has a nonnegative value. Don't assume
13111 size_t fits in 'long'.
13112 (gs_load): Use printmax_t to print the widest integers possible.
13113 Check for integer overflow when computing image height and width.
13115 2011-08-26 Eli Zaretskii <eliz@gnu.org>
13117 * xdisp.c (redisplay_window): Don't force window start if point
13118 will be invisible in the resulting window. (Bug#9324)

13122 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
13123 the display spec is of the form `(space ...)'.
13124 (handle_display_spec): Return the value returned by
13125 handle_single_display_spec, not just 1 or zero.
13126 (handle_single_display_spec): If the display spec is of the form
13127 `(space ...)', and specifies display in the text area, return 2
13129 (try_cursor_movement): Check for the need to scroll more
13130 accurately, and prefer exact match for point under bidi.
13131 Don't advance `row' beyond the last row of the window.
13133 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
13134 into disp_prop; all users changed.
13136 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
13137 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
13138 for the text covered by the display property.

13148 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
13149 buffers, return left-to-right.
13150 (set_cursor_from_row): Consider candidate row a win if its glyph
13151 represents a newline and point is on that newline. Fixes cursor
13152 positioning on the newline at EOL of R2L text within L2R
13153 paragraph, and vice versa.
13154 (try_cursor_movement): Check continued rows, in addition to
13155 continuation rows. Fixes unwarranted scroll when point enters a
13156 continued line of R2L text within an L2R paragraph, or vice versa.
13157 (cursor_row_p): Consider the case of point being equal to
13158 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
13159 from the end of a short line to the beginning of a continued line
13160 of R2L text within L2R paragraph.
13161 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
13162 composed characters.

13175 * nsfont.m (ns_otf_to_script): Fix typo.
13177 2011-08-22 Kenichi Handa <handa@m17n.org>
13179 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
13180 extra slot even if the purpose is char-code-property-table.
13182 2011-08-23 Eli Zaretskii <eliz@gnu.org>
13184 * xdisp.c (redisplay_window): When computing centering_position,
13185 account for the height of the header line. (Bug#8874)
13187 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
13188 instead of CHAR_TO_BYTE. Fixes a crash when a completion
13189 candidate is selected by the mouse, and that candidate has a
13190 composed character under the mouse.
13192 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
13193 coordinates reported by pos-visible-in-window-p for a composed
13194 character in column zero.
13196 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
13198 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
13200 2011-08-22 Eli Zaretskii <eliz@gnu.org>
13202 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
13203 consider it a hit if to_charpos is anywhere in the range of the
13204 composed buffer positions.
13206 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
13208 * image.c (gif_load): Don't assume that each subimage has the same
13209 dimensions as the base image. Handle disposal method that is
13210 "undefined" by the gif spec (Bug#9335).
13212 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
13214 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
13215 (Fcondition_case): Document `debug' symbol in error handler.
13217 2011-08-19 Eli Zaretskii <eliz@gnu.org>
13219 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
13220 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
13221 from an Org mode buffer to a Speedbar frame.
13223 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
13224 a composition, take its buffer position from IT->cmp_it.charpos.
13225 Fixes cursor positioning at the beginning of a line that begins
13226 with a composed character.
13228 2011-08-18 Eli Zaretskii <eliz@gnu.org>
13230 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
13231 character bidirectional type, use STRONG_L instead. Fixes crashes
13232 in a buffer produced by `describe-categories'.
13234 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
13235 members before the level stack, so they would be saved and
13236 restored when copying iterator state. Fixes incorrect reordering
13237 around TABs covered by display properties.
13239 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
13241 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

13245 * eval.c (internal_condition_case, internal_condition_case_1)
13246 (internal_condition_case_2, internal_condition_case_n):
13247 Remove unnecessary aborts (Bug#9081).
13249 2011-08-17 Eli Zaretskii <eliz@gnu.org>
13251 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
13252 has no `load' handler, try opening the file locally. (Bug#9311)
13254 2011-08-16 Ken Brown <kbrown@cornell.edu>
13256 * gmalloc.c: Expand comment.
13258 2011-08-16 Eli Zaretskii <eliz@gnu.org>
13260 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
13261 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
13263 2011-08-16 Ken Brown <kbrown@cornell.edu>
13265 Fix memory allocation problems in Cygwin build (Bug#9273).
13267 * unexcw.c ( __malloc_initialized): Declare external variable.
13268 (fixup_executable): Force the dumped emacs to reinitialize malloc.
13270 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
13272 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the

13298 biditype.h and bidimirror.h.
13300 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
13301 coordinates of the iterator when restoring from ppos_it.
13304 2011-08-14 Kenichi Handa <handa@m17n.org>
13306 * process.c (create_process): Call setup_process_coding_systems
13307 after the pid of the process is set to -1 (Bug#8162).
13309 2011-08-14 Eli Zaretskii <eliz@gnu.org>
13311 * xdisp.c (move_it_in_display_line_to): Don't invoke
13312 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
13313 ppos_it. Fixes vertical cursor motion when line beginning is
13314 covered by an image. (Bug#9296)
13316 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
13318 * nsterm.h (ns_run_ascript): Declare.
13319 (NSAPP_DATA2_RUNASSCRIPT): Define.
13321 * nsfns.m (as_script, as_result, as_status): New static variables.
13322 (ns_run_ascript): New function.
13323 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
13324 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
13325 the event loop. Get status from as_status (Bug#7276).
13327 * nsterm.m (sendEvent): If event is NSApplicationDefined and
13328 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
13329 the event loop (Bug#7276).
13331 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
13333 * gnutls.c (QCgnutls_bootprop_priority)

13354 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
13355 (Fnetwork_interface_list): Allocate in increments of bytes instead
13356 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
13357 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
13359 (struct ifflag_def): notrailers is smart on OSX.
13360 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
13361 Get hardware address with getifaddrs if available.
13363 2011-08-12 Eli Zaretskii <eliz@gnu.org>
13365 * xdisp.c (iterate_out_of_display_property): xassert that
13366 IT->position is set to within IT->object's boundaries. Break from
13367 the loop as soon as EOB is reached; avoids infloops in redisplay
13368 when IT->position is set up wrongly due to some bug.
13369 Set IT->current to match the bidi iterator unconditionally.
13370 (push_display_prop): Allow GET_FROM_STRING as IT->method on
13371 entry. Force push_it to save on the stack the current
13372 buffer/string position, to be restored by pop_it. Fix flags in
13373 the iterator structure wrt the object coming from a display
13374 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
13375 properties. (Bug#9284)
13377 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
13379 * fontset.c (fontset_get_font_group): Add proper type checks.

13385 and LC_VERSION_MIN_MACOSX.
13386 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
13387 (dump_it) [LC_FUNCTION_STARTS]: Use it.
13389 2011-08-08 Eli Zaretskii <eliz@gnu.org>
13391 * xdisp.c (forward_to_next_line_start): Allow to use the
13392 no-display-properties-and-no-overlays under bidi display.
13393 Set disp_pos in the bidi iterator to avoid searches for display
13394 properties and overlays.
13396 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
13398 * editfns.c (Fset_time_zone_rule): Document relationship with the
13401 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
13402 the font entity extracted from the cache (Bug#8109).
13404 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
13406 * composite.c (autocmp_chars): Don't reset point. That is done by
13407 restore_point_unwind (Bug#5984).
13409 2011-08-07 Juri Linkov <juri@jurta.org>
13411 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
13412 to show the arg `TIME' instead of `TIMEVAL'.
13414 2011-08-06 Eli Zaretskii <eliz@gnu.org>
13416 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
13417 display property strides EOL and includes a newline, as in
13418 longlines-mode. (Bug#9254)
13419 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
13420 word-wrap under bidirectional display. (Bug#9224)
13422 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
13423 is non-zero, even if the data buffer is NULL. Fixes a crash in
13424 vertical-motion with longlines-mode. (Bug#9254)
13426 2011-08-05 Eli Zaretskii <eliz@gnu.org>
13428 * bidi.c <bidi_cache_total_alloc>: Now static.
13429 (bidi_initialize): Initialize bidi_cache_total_alloc.
13431 * xdisp.c (display_line): Release buffer allocated for shelved bidi
13434 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
13435 amount allocated this far in `bidi_cache_total_alloc'.
13436 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
13437 non-zero, only free the data buffer without restoring the cache
13438 contents. All callers changed.
13440 * dispextern.h (bidi_unshelve_cache): Update prototype.
13442 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
13443 (move_it_in_display_line, move_it_to)
13444 (move_it_vertically_backward, move_it_by_lines): Replace the call
13445 to xfree to an equivalent call to bidi_unshelve_cache.
13446 (move_it_in_display_line_to): Fix logic of returning
13447 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
13449 2011-08-05 Eli Zaretskii <eliz@gnu.org>
13451 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
13452 came from a string character with a `cursor' property. (Bug#9229)
13454 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
13456 * Makefile.in (LIB_PTHREAD): New variable.
13457 (LIBES): Add LIB_PTHREAD (Bug#9216).
13459 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
13460 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
13462 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
13464 * regex.c (re_iswctype): Remove some redundant boolean conversions.
13466 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
13468 * xterm.c (x_find_topmost_parent): New function.
13469 (x_set_frame_alpha): Find topmost parent window with
13470 x_find_topmost_parent and set the property there also (bug#9181).
13471 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
13473 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
13475 * callproc.c (Fcall_process): Avoid vfork clobbering
13476 the local vars buffer, coding_systems, current_dir.
13478 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
13480 * keymap.c (Fmake_composed_keymap): Move to subr.el.
13482 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
13484 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
13485 so that it is not optimized away.
13487 * xdisp.c (compute_display_string_pos): Remove unused local.
13489 2011-08-02 Eli Zaretskii <eliz@gnu.org>
13491 Fix slow cursor motion and scrolling in large buffers with
13492 selective display, like Org Mode buffers. (Bug#9218)
13494 * dispextern.h (struct bidi_it): New member disp_prop_p.
13496 * xdisp.c: Remove one-slot cache of display string positions.
13497 (compute_display_string_pos): Accept an additional argument
13498 DISP_PROP_P; callers changed. Scan at most 5K characters forward
13499 for a display string or property. If found, set DISP_PROP_P
13502 * bidi.c (bidi_fetch_char): Accept an additional argument
13503 DISP_PROP_P, and pass it to compute_display_string_pos.
13504 Only handle text covered by a display string if DISP_PROP_P is returned
13505 non-zero. All callers of bidi_fetch_char changed.
13507 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
13509 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
13511 2010-12-03 Don March <don@ohspite.net>
13513 * keymap.c (Fdefine_key): Fix non-prefix key error message when
13514 last character M-[char] is translated to ESC [char] (bug#7541).
13516 2011-08-02 Kenichi Handa <handa@m17n.org>
13518 * lisp.h (uniprop_table): Extern it.
13520 * chartab.c (uniprop_table): Make it non-static.
13522 2011-08-01 Eli Zaretskii <eliz@gnu.org>
13524 * xdisp.c (forward_to_next_line_start): Accept additional argument
13525 BIDI_IT_PREV, and store into it the state of the bidi iterator had
13527 (reseat_at_next_visible_line_start): Use the bidi iterator state
13528 returned by forward_to_next_line_start to restore the state of
13529 it->bidi_it after backing up to previous newline. (Bug#9212)
13531 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
13533 * regex.c (re_comp): Protoize.
13534 (re_exec): Fix return type.
13535 (regexec): Fix type of `ret'. (Bug#9203)
13537 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13539 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
13540 This is needed if max-image-size is a floating-point number.
13542 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
13544 * print.c (print_object): Print empty symbol as ##.
13546 * lread.c (read1): Read ## as empty symbol.
13548 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
13550 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
13551 setting frame foreground color (Bug#9175).
13552 (x_set_background_color): Likewise.
13554 * nsmenu.m (-setText): Size tooltip dimensions precisely to
13555 contents (Bug#9176).
13556 (EmacsTooltip -init): Remove bezels and add shadows to
13559 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
13560 or scroll bar (Bug#8470).
13562 * nsfont.m (nsfont_open): Remove assignment to voffset and
13563 unnecessary vars hshink, expand, hd, full_height, min_height.
13564 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
13566 * nsterm.h (nsfont_info): Remove voffset field.
13568 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
13570 Implement strike-through and overline on NextStep (Bug#8863).
13572 * nsfont.m (nsfont_open): Use underline position provided by font,
13573 instead of hard-coded value of 2.
13574 (nsfont_draw): Call ns_draw_text_decoration instead.
13576 * nsterm.h: Add declaration for ns_draw_text_decoration.
13578 * nsterm.m (ns_draw_text_decoration): New function for drawing
13579 underline, overline, and strike-through.
13580 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
13581 ns_draw_text_decoration. Change treatment of cursor drawing to
13582 accommodate underlining, etc.
13584 2011-07-28 Eli Zaretskii <eliz@gnu.org>
13586 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
13589 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13591 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
13592 Without this fix, if a signal arrives just after memory fills up,
13593 'malloc' might be invoked reentrantly.
13595 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
13596 In other words, assume that every image size is allowed, on non-X
13597 hosts. This assumption is probably wrong, but it lets Emacs compile.
13599 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
13601 * regex.c (re_iswctype): Convert return values to boolean.
13603 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
13605 * xdisp.c (compute_display_string_pos): Don't use cached display
13606 string position if the buffer had its restriction changed.
13609 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13611 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
13613 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13615 Integer signedness and overflow and related fixes. (Bug#9079)
13617 * bidi.c: Integer size and overflow fixes.
13618 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
13619 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
13620 (bidi_cache_find_level_change, bidi_cache_ensure_space)
13621 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
13622 (bidi_find_other_level_edge):
13623 Use ptrdiff_t instead of EMACS_INT where either will do.
13624 This works better on 32-bit hosts configured --with-wide-int.
13625 (bidi_cache_ensure_space): Check for size-calculation overflow.
13626 Use % rather than repeated addition, for better worst-case speed.
13627 Don't set bidi_cache_size until after xrealloc returns, because it
13629 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
13630 (bidi_cache_ensure_space): Also check that the bidi cache size
13631 does not exceed that of the largest Lisp string or buffer. See Eli
13632 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
13634 * alloc.c (__malloc_size_t): Remove.
13635 All uses replaced by size_t. See Andreas Schwab's note
13636 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
13638 * image.c: Improve checking for integer overflow.
13639 (check_image_size): Assume that f is nonnull, since
13640 it is always nonnull in practice. This is one less thing to
13641 worry about when checking for integer overflow later.
13642 (x_check_image_size): New function, which checks for integer
13643 overflow issues inside X.
13644 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
13645 This removes the need for a memory_full check.
13646 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
13647 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
13648 (xbm_read_bitmap_data): Change locals back to 'int', since
13649 their values must fit in 'int'.
13650 (xpm_load_image, png_load, tiff_load):
13651 Invoke x_create_x_image_and_pixmap earlier,
13652 to avoid much needless work if the image is too large.
13653 (tiff_load): Treat overly large images as if
13654 x_create_x_image_and_pixmap failed, not as malloc failures.
13655 (gs_load): Use x_check_image_size.
13657 * gtkutil.c: Omit integer casts.
13658 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
13659 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
13661 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
13663 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
13664 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
13665 would wrongly return t on a 64-bit host.
13667 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
13668 The plain *_OVERFLOW macros run afoul of GCC bug 49705
13669 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
13670 and therefore cause GCC to emit a bogus diagnostic in some cases.
13672 * image.c: Integer signedness and overflow and related fixes.
13673 This is not an exhaustive set of fixes, but it's time to
13674 record what I've got.
13675 (lookup_pixel_color, check_image_size): Remove redundant decls.
13676 (check_image_size): Don't assume that arbitrary EMACS_INT values
13677 fit in 'int', or that arbitrary 'double' values fit in 'int'.
13678 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
13679 (tiff_load, imagemagick_load_image):
13680 Check for overflow in size calculations.
13681 (x_create_x_image_and_pixmap): Remove unnecessary test for
13682 xmalloc returning NULL; that can't happen.
13683 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
13684 (xpm_color_bucket): Use better integer hashing function.
13685 (xpm_cache_color): Don't possibly over-allocate memory.
13686 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
13687 (gif_memory_source):
13688 Use ptrdiff_t, not int or size_t, to record sizes.
13689 (png_load): Don't assume values greater than 2**31 fit in 'int'.
13690 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
13691 either works, as we prefer signed integers.
13692 (tiff_read_from_memory, tiff_write_from_memory):
13693 Return tsize_t, not size_t, since that's what the TIFF API wants.
13694 (tiff_read_from_memory): Don't fail simply because the read would
13695 go past EOF; instead, return a short read.
13696 (tiff_load): Omit no-longer-needed casts.
13697 (Fimagemagick_types): Don't assume size fits into 'int'.
13699 Improve hashing quality when configured --with-wide-int.
13700 * fns.c (hash_string): New function, taken from sxhash_string.
13701 Do not discard information about ASCII character case; this
13702 discarding is no longer needed.
13703 (sxhash-string): Use it. Change sig to match it. Caller changed.
13704 * lisp.h: Declare it.
13705 * lread.c (hash_string): Remove, since we now use fns.c's version.
13706 The fns.c version returns a wider integer if --with-wide-int is
13707 specified, so this should help the quality of the hashing a bit.
13709 * emacs.c: Integer overflow minor fix.
13710 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
13711 Define only if GNU_LINUX.
13712 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
13714 * dispnew.c: Integer signedness and overflow fixes.
13715 Remove unnecessary forward decls, that were a maintenance hassle.
13716 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
13718 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
13719 (scrolling_window): Use ptrdiff_t, not int, for byte count.
13720 (prepare_desired_row, line_draw_cost):
13721 Use int, not unsigned, where either works.
13722 (save_current_matrix, restore_current_matrix):
13723 Use ptrdiff_t, not size_t, where either works.
13724 (init_display): Check for overflow more accurately, and without
13725 relying on undefined behavior.
13727 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
13728 Remove, replacing with the new symbols in lisp.h. All uses changed.
13729 * fileio.c (make_temp_name):
13730 * filelock.c (lock_file_1, lock_file):
13731 * xdisp.c (message_dolog):
13732 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
13733 Use pMd etc. instead.
13734 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
13735 replacing the pWIDE etc. symbols removed from editfns.c.
13737 * keyboard.h (num_input_events): Now uintmax_t.
13738 This is (very slightly) less likely to mess up due to wraparound.
13741 * buffer.c: Integer signedness fixes.
13742 (alloc_buffer_text, enlarge_buffer_text):
13743 Use ptrdiff_t rather than size_t when either will do, as we prefer
13746 * alloc.c: Integer signedness and overflow fixes.
13747 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
13748 (__malloc_size_t): Default to size_t, not to int.
13749 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
13750 (Fgarbage_collect, mark_object_loop_halt, mark_object):
13751 Prefer ptrdiff_t to size_t when either would do, as we prefer
13753 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
13754 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
13755 Now const. Initialize with values that are in range even if char
13757 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
13758 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
13759 These functions do the right thing with sizes > 2**32.
13760 (check_depth): Now ptrdiff_t, not int.
13761 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
13762 Adjust to new way of storing sizes. Check for size overflow bugs
13764 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
13765 slightly wrong anyway, as it missed one instance of
13766 XMALLOC_OVERRUN_CHECK_OVERHEAD.
13767 (refill_memory_reserve): Omit needless cast to size_t.
13768 (mark_object_loop_halt): Mark as externally visible.
13770 * xselect.c: Integer signedness and overflow fixes.
13771 (Fx_register_dnd_atom, x_handle_dnd_message):
13772 Use ptrdiff_t, not size_t, since we prefer signed.
13773 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
13774 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
13775 x_dnd_atoms_size and x_dnd_atoms_length.
13777 * doprnt.c: Prefer signed to unsigned when either works.
13779 * doprnt.c (doprnt):
13781 * xdisp.c (vmessage):
13782 Use ptrdiff_t, not size_t, when using or implementing doprnt,
13783 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
13784 prefer signed arithmetic to avoid comparison confusion.
13785 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
13786 but is a bit tricky.
13788 Assume freestanding C89 headers, string.h, stdlib.h.
13789 * data.c, doprnt.c, floatfns.c, print.c:
13790 Include float.h unconditionally.
13791 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
13792 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
13793 * regex.c: Likewise for stddef.h, string.h.
13794 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
13795 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
13796 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
13797 (STDC_HEADERS): Remove obsolete defines.
13798 * sysdep.c: Include limits.h unconditionally.
13800 Assume support for memcmp, memcpy, memmove, memset.
13801 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
13802 * regex.c (memcmp, memcpy):
13803 Remove; we assume C89 now.
13805 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
13806 (__malloc_safe_bcopy): Remove; no longer needed.
13808 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
13809 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
13810 well either way, and we prefer signed to unsigned.
13812 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
13814 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
13815 closes the connection while we're reading (bug#9182).
13817 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
13819 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
13820 are specified (Bug#9168).
13822 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
13824 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
13825 Found by GCC static checking and --with-wide-int on a 32-bit host.
13827 2011-07-25 Eli Zaretskii <eliz@gnu.org>
13829 * xdisp.c (compute_display_string_pos): Fix logic of caching
13830 previous display string position. Initialize cached_prev_pos to
13831 -1. Fixes slow-down at the beginning of a buffer.
13833 2011-07-24 Eli Zaretskii <eliz@gnu.org>
13835 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
13836 for attrs[LFACE_FONTSET_INDEX].
13838 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
13840 * xml.c (parse_region): Remove unused local
13841 that was recently introduced.
13843 2011-07-23 Eli Zaretskii <eliz@gnu.org>
13845 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
13846 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
13848 * xdisp.c (move_it_in_display_line_to): Record the best matching
13849 position for TO_CHARPOS while scanning the line, and restore it on
13850 exit if none of the characters scanned was an exact match.
13851 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
13852 when exact match is impossible due to invisible text, and the
13853 lines are truncated.
13855 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
13857 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
13860 2011-07-22 Eli Zaretskii <eliz@gnu.org>
13862 Fix a significant slow-down of cursor motion with C-n, C-p,
13863 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
13864 auto-repeat under bidi redisplay in fontified buffers.
13865 * xdisp.c (compute_stop_pos_backwards): New function.
13866 (next_element_from_buffer): Call compute_stop_pos_backwards to
13867 find a suitable prev_stop when we find ourselves before
13869 (reseat): Don't look for prev_stop, as that could mean a very long
13871 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
13872 <cached_disp_overlay_modiff>: Cache for last found display string
13874 (compute_display_string_pos): Return the cached position if asked
13875 about the same buffer in the same area of character positions, and
13876 the buffer wasn't changed since the time the display string
13877 position was cached.
13879 2011-07-22 Eli Zaretskii <eliz@gnu.org>
13881 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
13882 is an integer, which is important for empty lines. (Bug#9149)
13884 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
13886 * frame.c (Fmodify_frame_parameters): In tty case, update the
13887 default face if necessary (Bug#4238).
13889 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
13891 * editfns.c (Fstring_to_char): No need to explain what a character
13892 is in the docstring (Bug#6576).
13894 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
13896 * xml.c (parse_region): Make sure we always return a tree.
13898 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
13900 * xml.c (parse_region): If a document contains only comments,
13903 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
13905 * xml.c (make_dom): Return comments, too.
13907 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
13910 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
13911 and the surrounding thread.
13912 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
13913 rather than fgets, and retry after EINTR. Otherwise, 'emacs
13914 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
13916 * s/openbsd.h (BROKEN_SIGIO): Define.
13917 * unexelf.c (unexec) [__OpenBSD__]:
13918 Don't update the .mdebug section of the Alpha COFF symbol table.
13920 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
13922 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
13925 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
13927 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
13928 This fixes some race conditions on the permissions of any newly
13931 * alloc.c (valid_pointer_p): Use pipe, not open.
13932 This fixes some permissions issues when debugging.
13934 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
13935 If fchown fails to set both uid and gid, try to set just gid,
13936 as that is sometimes allowed. Adjust the file's mode to eliminate
13937 setuid or setgid bits that are inappropriate if fchown fails.
13939 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
13941 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
13942 to compare Lisp_Objects.

13945 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
13947 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
13949 * lread.c (read_integer): Unread even EOF character.
13950 (read1): Likewise. Properly record start position of symbol.
13952 * lread.c (read1): Read `#:' as empty uninterned symbol if no
13953 symbol character follows.
13955 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
13957 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
13958 This works around a problem with the previous change to Fcopy_file.
13959 Recent glibc declares fchown with __attribute__((warn_unused_result)),
13960 and without this change, GCC might complain about discarding
13961 fchown's return value.
13963 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
13965 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
13967 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
13969 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
13971 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
13973 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
13974 it's used from the C level.
13976 * process.c: Use the same condition for POLL_FOR_INPUT in both
13977 keyboard.c and process.c (bug#1858).
13979 2011-07-09 Lawrence Mitchell <wence@gmx.li>
13981 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
13982 (Fgnutls_boot): Use it.
13984 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
13986 * doc.c (Fsubstitute_command_keys): Revert last change.
13988 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
13990 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
13991 quotes the next character, and doesn't affect other longer
13992 sequences (bug#8935).
13994 * lread.c (syms_of_lread): Clarify that is isn't only
13995 `eval-buffer' and `eval-defun' that's affected by
13996 `lexical-binding' (bug#8460).
13998 2011-07-15 Eli Zaretskii <eliz@gnu.org>
14000 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
14001 bidi redisplay when a line includes both an image and is truncated.
14003 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
14005 Fix minor problems found by static checking.
14006 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
14007 (elsz): Now a signed constant, not a size_t var. We prefer signed
14008 types to unsigned, to avoid integer comparison confusion. Without
14009 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
14010 "cannot optimize loop, the loop counter may overflow", a symptom
14012 * indent.c (Fvertical_motion): Mark locals as initialized.
14013 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
14015 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
14017 * search.c (Fre_search_backward): Mention `case-fold-search' in
14018 all the re_search_* functions (bug#8138).

14038 buffer position was specified. Initialize paragraph_embedding to
14040 (reseat_to_string): Initialize the bidi iterator.
14041 (display_string): If we need to ignore text properties of
14042 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
14043 original value of -1 will not work with bidi.)
14044 (compute_display_string_pos): First arg is now struct
14045 `text_pos *'; all callers changed. Support display properties on
14047 (compute_display_string_end): Support display properties on Lisp
14049 (init_iterator, reseat_1, reseat_to_string): Initialize the
14050 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
14051 when iterating on a string not from display properties).
14052 (compute_display_string_pos, compute_display_string_end):
14053 Fix calculation of the object to scan. Fixes an error when using
14055 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
14056 base_level_stop; instead, set base_level_stop to BEGV.
14057 Fixes crashes in vertical-motion.
14058 (next_element_from_buffer): Improve commentary for when
14059 the iterator is before prev_stop.
14060 (init_iterator): Initialize bidi_p from the default value of
14061 bidi-display-reordering, not from buffer-local value. Use the
14062 buffer-local value only if initializing for buffer iteration.
14063 (handle_invisible_prop): Support invisible properties on strings
14064 that are being bidi-reordered.

14072 (init_iterator): Don't initialize it->bidi_p for strings
14074 (reseat_to_string): Initialize it->bidi_p for strings here.

14081 character that is not the first one in the visual order.
14082 (get_visually_first_element): New function, refactored from common
14083 parts of next_element_from_buffer, next_element_from_string, and
14084 next_element_from_c_string.
14085 (tool_bar_lines_needed, redisplay_tool_bar)
14086 (display_menu_bar): Force left-to-right direction. Add a FIXME
14087 comment for making that be controlled by a user option.
14088 (push_it, pop_it): Save and restore the state of the
14089 bidi iterator. Save and restore the bidi_p flag.

14093 (handle_single_display_spec): Set up it->bidi_it for iteration
14094 over a display string, and call bidi_init_it.

14096 (get_overlay_strings_1, push_display_prop): Set up the bidi
14097 iterator for displaying display or overlay strings.
14098 (forward_to_next_line_start): Don't use the shortcut if
14100 (back_to_previous_visible_line_start): If handle_display_prop
14101 pushed the iterator stack, restore the internal state of the bidi
14102 iterator by calling bidi_pop_it same number of times.
14103 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
14104 and we are bidi-iterating, don't decrement the iterator position;
14105 instead, set the first_elt flag in the bidi iterator, to produce
14107 (reseat_1): Remove redundant setting of string_from_display_prop_p.
14108 (push_display_prop): xassert that we are iterating a buffer.
14109 (push_it, pop_it): Save and restore paragraph_embedding member.
14110 (handle_single_display_spec, next_overlay_string)
14111 (get_overlay_strings_1, reseat_1, reseat_to_string)
14112 (push_display_prop): Set up the `unibyte' member of bidi_it.string
14113 correctly. Don't assume unibyte strings are not bidi-reordered.
14114 (compute_display_string_pos)
14115 (compute_display_string_end): Fix handling the case of C string.

14120 (pop_it): Call iterate_out_of_display_property only if we are
14121 popping after iteration over a string that came from a display
14122 property. Fix a typo in popping stretch info. Add an assertion
14123 for verifying that the iterator position is in sync with the bidi
14125 (handle_single_display_spec, get_overlay_strings_1)
14126 (push_display_prop): Fix initialization of paragraph direction for
14127 string when that of the parent object is not yet determined.

14139 (try_scrolling, redisplay_window, display_line): Use them when
14140 saving a temporary copy of the iterator and restoring it back.
14141 (back_to_previous_visible_line_start, reseat_1)
14142 (init_iterator): Empty the bidi cache "stack".
14143 (move_it_in_display_line_to): If iterator ended up at
14144 EOL, but we never saw any buffer positions smaller than
14145 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
14146 motion in bidi-reordered lines.

14150 displayed in margins. (Bug#8133) (Bug#8867)
14151 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
14153 (pos_visible_p): Support positions in bidi-reordered lines.
14154 Save and restore bidi cache.
14156 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
14157 (bidi_paragraph_info): Delete unused struct.
14158 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
14159 (bidi_cache_start): New variable.
14160 (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not

14177 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
14178 can now be zero (for strings); special values 0 and -1 were
14179 changed to -1 and -2, respectively.
14180 (bidi_char_at_pos): New function.
14181 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):

14209 * dispextern.h (struct bidi_string_data): New structure.
14210 (struct bidi_it): New member `string'. Make flag members be 1-bit
14211 fields, and put them last in the struct.
14212 (compute_display_string_pos, compute_display_string_end):
14214 (bidi_push_it, bidi_pop_it): Add prototypes.
14215 (struct iterator_stack_entry): New members bidi_p,
14216 paragraph_embedding, and from_disp_prop_p.
14217 (struct it): Member bidi_p is now a bit field 1 bit wide.
14218 (bidi_shelve_cache, bidi_unshelve_cache):
14219 Declare prototypes.
14221 * .gdbinit (xvectype, xvector, xcompiled, xchartable, xboolvector)

14264 Pass Qx_lost_selection_functions rather than
14265 Vx_lost_selection_functions to Frun_hook_with_args.
14267 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
14269 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
14270 The old code sometimes used this field without initializing it.
14272 * alloc.c (gc_sweep): Don't read past end of array.
14273 In theory, the old code could also have corrupted Emacs internals,
14274 though it'd be very unlikely.
14276 2011-07-12 Andreas Schwab <schwab@linux-m68k.org>
14278 * character.c (Fcharacterp): Don't advertise optional ignored
14279 argument. (Bug#4026)

14537 (clone_per_buffer_values): Don't assume that
14538 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
14539 This isn't true in general, and it's particularly not true
14540 if Emacs is configured with --with-wide-int.
14541 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
14542 New macros, used in the buffer.c change.

14578 Random fixes. E.g., (random) never returned negative values.
14579 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
14580 subseconds part to the entropy, as that's a bit more random.
14581 Prefer signed to unsigned, since the signedness doesn't matter and
14582 in general we prefer signed. When given a limit, use a
14583 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
14584 latter isn't right if USE_2_TAGS_FOR_INTS.
14585 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
14586 not 0..VALMASK. Don't discard "excess" bits that random () returns.
14588 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
14590 * textprop.c (text_property_stickiness):
14591 Obey Vtext_property_default_nonsticky.

14596 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
14598 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
14599 This is more efficient than Ffile_directory_p and avoids a minor race.
14601 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
14603 * buffer.c (Foverlay_put): Say what the return value is
14606 * fileio.c (barf_or_query_if_file_exists): Check first if the file
14607 is a directory before asking whether to use the file name
14609 (barf_or_query_if_file_exists): Make the "File is a directory"
14610 error be more correct.
14612 * fns.c (Frequire): Remove the mention of the .gz files, since
14613 that's installation-specific, but keep the mention of
14614 `get-load-suffixes'.
14616 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
14618 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

14626 Qgnutls_bootprop_verify_error (which is no longer used).
14628 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
14629 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
14630 Also (re)move comments that are misplaced or no longer relevant.
14632 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
14634 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

14652 2011-07-02 Chong Yidong <cyd@stupidchicken.com>
14654 * keyboard.c (command_loop_1): If a down-mouse event is unbound,
14655 leave any prefix arg for the up event (Bug#1586).
14657 2011-07-02 Lars Magne Ingebrigtsen <larsi@gnus.org>
14659 * lread.c (syms_of_lread): Mention single symbols defined by
14660 `defvar' or `defconst' (bug#7154).
14662 * fns.c (Frequire): Mention .el.gz files (bug#7314).
14663 (Frequire): Mention get-load-suffixes.
14665 2011-07-02 Martin Rudalics <rudalics@gmx.at>
14667 * window.h (window): Remove clone_number slot.
14668 * window.c (Fwindow_clone_number, Fset_window_clone_number):

14686 (Fcopy_keymap): Handle embedded parents.
14687 (Fcommand_remapping, define_as_prefix): Simplify.
14688 (Fkey_binding): Simplify.

14690 minibuffer-local-filename-completion-map,
14691 minibuffer-local-must-match-map, and
14692 minibuffer-local-filename-must-match-map to Elisp.
14693 (syms_of_keymap): Defsubr make-composed-keymap.
14694 * keyboard.c (menu_bar_items): Use map_keymap_canonical.
14695 (parse_menu_item): Trivial simplification.
14697 2011-07-01 Glenn Morris <rgm@gnu.org>
14699 * Makefile.in (SETTINGS_LIBS): Fix typo.

14723 (xgselect_initialize): Ditto.
14725 * process.c: Add defined (HAVE_GSETTINGS) for xgselect.h

14729 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
14731 * eval.c (struct backtrace): Simplify and port the data structure.
14732 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
14733 signed bit field, as this assumption is not portable and it makes
14734 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
14735 "char debug_on_exit : 1" as this is not portable either; instead,
14736 use the portable "unsigned int debug_on_exit : 1". Remove unused
14737 member evalargs. Remove obsolete comments about cc bombing out.
14739 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

14905 * print.c (printchar, strout): Check for string overflow.
14906 (PRINTPREPARE, printchar, strout):
14907 Don't set size unless allocation succeeds.
14909 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
14910 for sizes. Check for string overflow more accurately.
14911 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
14913 * macros.c: Integer and buffer overflow fixes.
14914 * keyboard.h (struct keyboard.kbd_macro_bufsize):
14915 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

14919 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
14921 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
14923 * lread.c: Integer overflow fixes.
14924 (read_integer): Radix is now EMACS_INT, not int,
14925 to improve quality of diagnostics for out-of-range radices.
14926 Calculate buffer size correctly for out-of-range radices.
14927 (read1): Check for integer overflow in radices, and in
14928 read-circle numbers.
14929 (read_escape): Avoid int overflow.
14930 (Fload, openp, read_buffer_size, read1)
14931 (substitute_object_recurse, read_vector, read_list, map_obarray):
14932 Use ptrdiff_t, not int, for sizes.

14947 2011-06-22 Leo Liu <sdl.web@gmail.com>
14949 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
14950 Move to minibuffer.el.
14952 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
14954 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
14955 The following patches are for when GLYPH_DEBUG && !XASSERT.
14956 * dispextern.h (trace_redisplay_p, dump_glyph_string):
14957 * dispnew.c (flush_stdout):
14958 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
14959 Mark as externally visible.
14960 * dispnew.c (check_window_matrix_pointers): Now static.
14961 * dispnew.c (window_to_frame_vpos):
14962 * xfns.c (unwind_create_frame):
14963 * xterm.c (x_check_font): Remove unused local.
14964 * scroll.c (CHECK_BOUNDS):
14965 * xfaces.c (cache_fache): Rename local to avoid shadowing.
14966 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
14967 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
14968 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
14969 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
14971 (debug_method_add): Use va_list and vsprintf rather than relying
14972 on undefined behavior with wrong number of arguments.
14973 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
14974 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
14975 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
14976 since we're not interested in debugging glyphs with old libraries.
14977 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
14978 GCC 4.6.0's static checking.
14980 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
14982 Integer overflow and signedness fixes (Bug#8873).

14998 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
14999 (.bitmaps_last, struct x_output.icon_bitmap):
15000 Use ptrdiff_t, not int, for bitmap indexes.
15001 (x_allocate_bitmap_record): Check for size overflow.
15002 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
15004 Use ptrdiff_t, not int, for overlay counts.
15005 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
15006 * editfns.c (overlays_around, get_pos_property):
15007 * textprop.c (get_char_property_and_overlay):
15008 * xdisp.c (next_overlay_change, note_mouse_highlight):
15009 * xfaces.c (face_at_buffer_position):
15010 * buffer.c (OVERLAY_COUNT_MAX): New macro.
15011 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
15012 (Fnext_overlay_change, Fprevious_overlay_change)
15013 (mouse_face_overlay_overlaps, Foverlays_in):
15014 Use ptrdiff_t, not int, for sizes.
15015 (overlays_at, overlays_in): Check for size-calculation overflow.
15017 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
15019 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
15020 (x_session_initialize): Do not assume string length fits in int.
15022 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
15023 This is unlikely, but can occur if DPI is outlandish.
15025 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
15026 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
15028 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
15029 * xrdb.c (magic_file_p, search_magic_path):
15030 Omit last arg SUFFIX; it was always 0. All callers changed.
15031 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
15033 * xfont.c (xfont_match): Avoid need for strlen.
15035 * xfns.c: Don't assume strlen fits in int.

15038 * xdisp.c (message_log_check_duplicate): Return intmax_t,
15039 not unsigned long, as we prefer signed integers. All callers changed.
15040 Detect integer overflow in repeat count.
15041 (message_dolog): Don't assume print length fits in 39 bytes.
15042 (display_mode_element): Don't assume strlen fits in int.
15044 * termcap.c: Don't assume sizes fit in int and never overflow.
15045 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
15046 (gobble_line): Check for size-calculation overflow.
15048 * minibuf.c (Fread_buffer):
15049 * lread.c (intern, intern_c_string):
15050 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

15063 * filelock.c: Fix some buffer overrun and integer overflow issues.
15064 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
15065 Reformulate so as not to need the command string.
15066 Invoke gzip -cd rather than gunzip, as it's more portable.
15067 (lock_info_type, lock_file_1, lock_file):
15068 Don't assume pid_t and time_t fit in unsigned long.
15069 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
15070 (current_lock_owner): Prefer signed type for sizes.
15071 Use memcpy, not strncpy, where memcpy is what is really wanted.
15072 Don't assume (via atoi) that time_t and pid_t fit in int.
15073 Check for time_t and/or pid_t out of range, e.g., via a network share.
15074 Don't alloca where an auto var works fine.
15076 * fileio.c: Fix some integer overflow issues.
15077 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
15078 Don't assume string length fits in int.
15079 (directory_file_name): Don't assume string length fits in long.
15080 (make_temp_name): Don't assume pid fits in int, or that its print
15081 length is less than 20.
15083 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
15085 * coding.c (make_subsidiaries): Don't assume string length fits in int.
15087 * callproc.c (child_setup): Rewrite to avoid two strlen calls.

15093 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
15094 (main): Don't invoke strlen when not needed.

15100 (Fgetenv_internal):
15101 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
15103 * lread.c (invalid_syntax): Omit length argument.
15104 All uses changed. This doesn't fix a bug, but it simplifies the
15105 code away from its former Hollerith-constant appearance, and it's
15106 one less 'int' to worry about when looking at integer-overflow issues.
15107 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
15109 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
15110 This didn't break anything, but it didn't help either.
15111 It's confusing to put a bogus integer in a place where the actual
15112 value does not matter.
15113 (LIST_END_P): Remove unused macro and its bogus comment.
15114 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
15116 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
15117 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
15119 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
15120 We prefer signed types, and the value cannot exceed the EMACS_INT
15121 range anyway (because otherwise the length would not be representable).
15122 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
15123 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
15124 This avoids a GCC warning when WIDE_EMACS_INT.
15126 * indent.c (sane_tab_width): New function.
15127 (current_column, scan_for_column, Findent_to, position_indentation)
15128 (compute_motion): Use it. This is just for clarity.
15129 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
15131 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
15133 * lisp.h (lint_assume): New macro.
15134 * composite.c (composition_gstring_put_cache):
15135 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
15137 * editfns.c, insdel.c:
15138 Omit unnecessary forward decls, to simplify future changes.
15140 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
15142 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
15144 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
15145 Use much-faster test for byte-length change.
15146 Don't assume string byte-length fits in 'int'.
15147 Check that character arg fits in 'int'.
15148 (mapcar1): Declare byte as byte, for clarity.
15150 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
15152 * fns.c (concat): Catch string overflow earlier.
15153 Do not rely on integer wraparound.
15155 * dispextern.h (struct it.overlay_strings_charpos)
15156 (struct it.selective): Now EMACS_INT, not int.
15157 * xdisp.c (forward_to_next_line_start)
15158 (back_to_previous_visible_line_start)
15159 (reseat_at_next_visible_line_start, next_element_from_buffer):
15160 Don't arbitrarily truncate the value of 'selective' to int.
15162 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
15164 * composite.c: Don't truncate sizes to 'int'.
15165 (composition_gstring_p, composition_reseat_it)
15166 (composition_adjust_point): Use EMACS_INT, not int.
15167 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
15168 not EMACS_UINT, for indexes.
15170 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
15172 * buffer.c: Include <verify.h>.
15173 (struct sortvec.priority, struct sortstr.priority):
15174 Now EMACS_INT, not int.
15175 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
15176 (struct sortstr.size, record_overlay_string)
15177 (struct sortstrlist.size, struct sortlist.used):
15178 Don't truncate size to int.
15179 (record_overlay_string): Check for size-calculation overflow.
15180 (init_buffer_once): Check at compile-time, not run-time.
15182 2011-06-22 Jim Meyering <meyering@redhat.com>
15184 Don't leak an XBM-image-sized buffer
15185 * image.c (xbm_load): Free the image buffer after using it.
15187 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
15190 * composite.c (find_automatic_composition): Omit needless 'return 0;'
15191 that Sun C diagnosed.
15192 * fns.c (secure_hash): Fix pointer signedness issue.
15193 * intervals.c (static_offset_intervals): New function.
15194 (offset_intervals): Use it.
15196 2011-06-21 Leo Liu <sdl.web@gmail.com>
15199 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
15202 * fns.c (secure_hash): Rename from crypto_hash_function and change
15203 the first arg to accept symbols.
15204 (Fsecure_hash): New primitive.
15205 (syms_of_fns): New symbols.
15207 2011-06-20 Deniz Dogan <deniz@dogan.se>
15209 * process.c (Fset_process_buffer): Clarify return value in
15212 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
15214 * dispnew.c (add_window_display_history): Use BVAR.
15216 * xdisp.c (debug_method_add): Use BVAR.
15217 (check_window_end, dump_glyph_matrix, dump_glyph)
15218 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
15220 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
15223 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
15224 check till after the cache is created in init_frame_faces.
15226 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
15228 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
15230 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
15232 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
15233 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
15234 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
15236 Improve buffer-overflow checking (Bug#8873).
15237 * fileio.c (Finsert_file_contents):
15238 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
15239 Remove the old (too-loose) buffer overflow checks.
15240 They weren't needed, since make_gap checks for buffer overflow.
15241 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
15242 The old code merely checked for Emacs fixnum overflow, and relied
15243 on undefined (wraparound) behavior. The new code avoids undefined
15244 behavior, and also checks for ptrdiff_t and/or size_t overflow.
15246 * editfns.c (Finsert_char): Don't dump core with very negative counts.
15247 Tune. Don't use wider integers than needed. Don't use alloca.
15248 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
15250 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
15252 * insdel.c, lisp.h (buffer_overflow): New function.
15253 (insert_from_buffer_1, replace_range, replace_range_2):
15254 * insdel.c (make_gap_larger):
15255 * editfns.c (Finsert_char):
15256 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
15258 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
15260 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
15262 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
15264 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
15265 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
15267 * fileio.c: Don't assume EMACS_INT fits in off_t.
15268 (emacs_lseek): New static function.
15269 (Finsert_file_contents, Fwrite_region): Use it.
15270 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
15272 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
15274 * fns.c: Don't overflow int when computing a list length.
15275 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
15276 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
15277 truncation on 64-bit hosts. Check for QUIT every
15278 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
15279 faster and is responsive enough.
15280 (Flength): Report an error instead of overflowing an integer.
15281 (Fsafe_length): Return a float if the value is not representable
15282 as a fixnum. This shouldn't happen except in contrived situations.
15283 (Fnthcdr, Fsort): Don't assume list length fits in int.
15284 (Fcopy_sequence): Don't assume vector length fits in int.
15286 * alloc.c: Check that resized vectors' lengths fit in fixnums.
15287 (header_size, word_size): New constants.
15288 (allocate_vectorlike): Don't check size overflow here.
15289 (allocate_vector): Check it here instead, since this is the only
15290 caller of allocate_vectorlike that could cause overflow.
15291 Check that the new vector's length is representable as a fixnum.
15293 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
15294 The previous code was bogus. For example, next_almost_prime (32)
15295 returned 39, which is undesirable as it is a multiple of 3; and
15296 next_almost_prime (24) returned 25, which is a multiple of 5 so
15297 why was the code bothering to check for multiples of 7?
15299 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
15301 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
15303 Variadic C functions now count arguments with ptrdiff_t.
15304 This partly undoes my 2011-03-30 change, which replaced int with size_t.
15305 Back then I didn't know that the Emacs coding style prefers signed int.
15306 Also, in the meantime I found a few more instances where arguments
15307 were being counted with int, which may truncate counts on 64-bit
15308 machines, or EMACS_INT, which may be unnecessarily wide.
15309 * lisp.h (struct Lisp_Subr.function.aMANY)
15310 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
15311 Arg counts are now ptrdiff_t, not size_t.
15312 All variadic functions and their callers changed accordingly.
15313 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
15314 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
15315 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
15316 * callint.c (Fcall_interactively): Check arg count for overflow,
15317 to avoid potential buffer overrun. Use signed char, not 'int',
15318 for 'varies' array, so that we needn't bother to check its size
15319 calculation for overflow.
15320 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
15321 * eval.c (apply_lambda):
15322 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
15323 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
15324 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
15326 * callint.c (Fcall_interactively): Don't use index var as event count.
15328 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
15329 * mem-limits.h (SIZE): Remove; no longer used.
15331 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
15333 Remove unnecessary casts.
15334 * xterm.c (x_term_init):
15335 * xfns.c (x_set_border_pixel):
15336 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
15337 These aren't needed now that we assume ANSI C.
15339 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
15340 It's more likely to cause problems (due to unsigned overflow)
15343 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
15345 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
15347 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
15349 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
15351 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
15353 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
15355 GLYPH_CODE_FACE returns EMACS_INT, not int.
15356 * dispextern.h (merge_faces):
15357 * xfaces.c (merge_faces):
15358 * xdisp.c (get_next_display_element, next_element_from_display_vector):
15359 Don't assume EMACS_INT fits in int.
15361 * character.h (CHAR_VALID_P): Remove unused parameter.
15362 * fontset.c, lisp.h, xdisp.c: All uses changed.
15364 * editfns.c (Ftranslate_region_internal): Omit redundant test.
15366 * fns.c (concat): Minor tuning based on overflow analysis.
15367 This doesn't fix any bugs. Use int to hold character, instead
15368 of constantly refetching from Emacs object. Use XFASTINT, not
15369 XINT, for value known to be a character. Don't bother comparing
15370 a single byte to 0400, as it's always less.
15372 * floatfns.c (Fexpt):
15373 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
15375 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
15378 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
15380 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
15381 Without this fix, on a 64-bit host (aset S 0 4294967386) would
15382 incorrectly succeed when S was a string, because 4294967386 was
15383 truncated before it was used.
15385 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
15386 Otherwise, an out-of-range integer could cause undefined behavior
15389 * composite.c: Use int, not EMACS_INT, for characters.
15390 (fill_gstring_body, composition_compute_stop_pos): Use int, not
15391 EMACS_INT, for values that are known to be in character range.
15392 This doesn't fix any bugs but is the usual style inside Emacs and
15393 may generate better code on 32-bit machines.
15395 Make sure a 64-bit char is never passed to ENCODE_CHAR.
15396 This is for reasons similar to the recent CHAR_STRING fix.
15397 * charset.c (Fencode_char): Check that character arg is actually
15398 a character. Pass an int to ENCODE_CHAR.
15399 * charset.h (ENCODE_CHAR): Verify that the character argument is no
15400 wider than 'int', as a compile-time check to prevent future regressions
15403 * character.c (char_string): Remove unnecessary casts.
15405 Make sure a 64-bit char is never passed to CHAR_STRING.
15406 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
15407 by silently ignoring the top 32 bits, allowing some values
15408 that were far too large to be valid characters.
15409 * character.h: Include <verify.h>.
15410 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
15411 arguments are no wider than unsigned, as a compile-time check
15412 to prevent future regressions in this area.
15414 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
15415 (Fsubst_char_in_region):
15417 * xdisp.c (decode_mode_spec_coding):
15418 Adjust to CHAR_STRING's new requirement.
15419 * editfns.c (Finsert_char, Fsubst_char_in_region):
15420 * fns.c (concat): Check that character args are actually
15421 characters. Without this test, these functions did the wrong
15422 thing with wildly out-of-range values on 64-bit hosts.
15424 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
15425 These casts should not be needed on 32-bit hosts, either.
15426 * keyboard.c (read_char):
15427 * lread.c (Fload): Remove casts to unsigned.
15429 * lisp.h (UNSIGNED_CMP): New macro.
15430 This fixes comparison bugs on 64-bit hosts.
15431 (ASCII_CHAR_P): Use it.
15432 * casefiddle.c (casify_object):
15433 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
15434 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
15435 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
15436 * dispextern.h (FACE_FROM_ID):
15437 * keyboard.c (read_char): Use UNSIGNED_CMP.
15439 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
15440 not to EMACS_INT, to avoid GCC warning.
15442 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
15444 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
15445 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
15446 isn't needed on 32-bit machines.
15448 * buffer.c (Fgenerate_new_buffer_name):
15449 Use EMACS_INT for count, not int.
15450 (advance_to_char_boundary): Return EMACS_INT, not int.
15452 * data.c (Qcompiled_function): Now static.
15454 * window.c (window_body_lines): Now static.
15456 * image.c (gif_load): Rename local to avoid shadowing.
15458 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
15459 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
15460 * alloc.c (make_save_value): Integer argument is now of type
15461 ptrdiff_t, not int.
15462 (mark_object): Use ptrdiff_t, not int.
15463 * lisp.h (pD): New macro.
15464 * print.c (print_object): Use it.
15466 * alloc.c: Use EMACS_INT, not int, to count objects.
15467 (total_conses, total_markers, total_symbols, total_vector_size)
15468 (total_free_conses, total_free_markers, total_free_symbols)
15469 (total_free_floats, total_floats, total_free_intervals)
15470 (total_intervals, total_strings, total_free_strings):
15471 Now EMACS_INT, not int. All uses changed.
15472 (Fgarbage_collect): Compute overall total using a double, so that
15473 integer overflow is less likely to be a problem. Check for overflow
15474 when converting back to an integer.
15475 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
15476 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
15477 These were 'int' variables that could overflow on 64-bit hosts;
15478 they were never used, so remove them instead of repairing them.
15479 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
15480 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
15481 Previously, this ceilinged at INT_MAX, but that doesn't work on
15483 (allocate_pseudovector): Don't use EMACS_INT when int would do.
15485 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
15486 (allocate_vectorlike): Check for ptrdiff_t overflow.
15487 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
15488 when a (possibly-narrower) signed value would do just as well.
15489 We prefer using signed arithmetic, to avoid comparison confusion.
15491 * alloc.c: Catch some string size overflows that we were missing.
15492 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
15493 for convenience in STRING_BYTES_MAX.
15494 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
15495 The definition here is exact; the one in lisp.h was approximate.
15496 (allocate_string_data): Check for string overflow. This catches
15497 some instances we weren't catching before. Also, it catches
15498 size_t overflow on (unusual) hosts where SIZE_MAX <= min
15499 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
15500 and ptrdiff_t and EMACS_INT are both 64 bits.
15502 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
15503 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
15504 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
15506 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
15508 * alloc.c (Fmake_string): Check for out-of-range init.
15510 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
15512 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
15514 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
15516 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
15517 xg_get_default_scrollbar_width.
15519 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
15520 (int_gtk_range_get_value): Move to the scroll bar part of the file.
15521 (style_changed_cb): Call update_theme_scrollbar_width and call
15522 x_set_scroll_bar_default_width and xg_frame_set_char_size for
15523 all frames (Bug#8505).
15524 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
15525 Call gtk_window_set_resizable if HAVE_GTK3.
15526 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
15527 and height if HAVE_GTK3 (Bug#8505).
15528 (scroll_bar_width_for_theme): New variable.
15529 (update_theme_scrollbar_width): New function.
15530 (xg_get_default_scrollbar_width): Move code to
15531 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
15532 (xg_initialize): Call update_theme_scrollbar_width.
15534 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
15536 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
15538 2011-06-12 Martin Rudalics <rudalics@gmx.at>
15540 * frame.c (make_frame): Call other_buffer_safely instead of
15543 * window.c (temp_output_buffer_show): Call display_buffer with
15544 second argument Vtemp_buffer_show_specifiers and reset latter
15545 immediately after the call.
15546 (Vtemp_buffer_show_specifiers): New variable.
15547 (auto_window_vscroll_p, next_screen_context_lines)
15548 (Vscroll_preserve_screen_position): Remove leading asterisks from
15551 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
15553 Fix minor problems found by GCC 4.6.0 static checking.
15554 * buffer.c (Qclone_number): Remove for now, as it's unused.
15555 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
15556 (record_buffer): Remove unused local.
15557 * frame.c (other_visible_frames, frame_buffer_list): Now static.
15558 (set_frame_buffer_list): Remove; unused.
15559 * frame.h (other_visible_frames): Remove decl.
15560 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
15561 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
15562 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
15564 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
15565 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
15566 Define only if HAVE_GPM.
15567 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
15568 (update_hints_inhibit): Remove; never set. All uses removed.
15569 * widgetprv.h (emacsFrameClassRec): Remove decl.
15570 * window.c (delete_deletable_window): Now returns void, since it
15571 wasn't returning anything.
15572 (compare_window_configurations): Remove unused locals.
15573 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
15574 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
15575 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
15576 the same widths as pointers. This follows up on the 2011-05-06 patch.
15577 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
15578 * xterm.h: Likewise.
15579 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
15581 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
15583 * makefile.w32-in: Update dependencies.
15584 (LISP_H): Add lib/intprops.h.
15586 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
15588 * image.c (gif_load): Add animation frame delay to the metadata.
15589 (syms_of_image): Use DEFSYM. New symbol `delay'.
15591 2011-06-11 Martin Rudalics <rudalics@gmx.at>
15593 * window.c (delete_deletable_window): Re-add.
15594 (Fset_window_configuration): Rewrite to handle dead buffers and
15595 consequently deletable windows.
15596 (window_tree, Fwindow_tree): Remove. Supply functionality in
15598 (compare_window_configurations): Simplify code.
15600 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
15602 * image.c (imagemagick_load_image): Fix type mismatch.
15603 (Fimagemagick_types): Likewise.
15605 * window.h (replace_buffer_in_windows): Declare.
15607 2011-06-11 Martin Rudalics <rudalics@gmx.at>
15609 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
15610 Qclone_number. Remove external declaration of Qdelete_window.
15611 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
15613 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
15614 Run Qbuffer_list_update_hook if allowed.
15615 (Fother_buffer): Rewrite doc-string. Major rewrite for new

16068 (bidi_cache_search, bidi_cache_iterator_state)
16069 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
16070 (bidi_level_of_next_char, bidi_move_to_visually_next):
16071 Support character positions inside a run of characters covered by a
16073 (bidi_paragraph_init, bidi_resolve_explicit_1)
16074 (bidi_level_of_next_char): Call bidi_fetch_char and
16075 bidi_fetch_char_advance instead of FETCH_CHAR and
16076 FETCH_CHAR_ADVANCE.
16077 (bidi_init_it): Initialize new members.
16078 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
16080 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
16081 instead of using explicit *_CHAR codes.
16082 (bidi_resolve_explicit, bidi_resolve_weak):
16083 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
16084 bidirectional text is supported only in multibyte buffers.
16085 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
16086 it to initialize the frame_window_p member of struct bidi_it.
16087 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
16088 (bidi_resolve_explicit, bidi_resolve_weak)
16089 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
16090 bidi_it->nchars is non-positive.
16091 (bidi_level_of_next_char): Don't try to lookup the cache for the
16092 next/previous character if nothing is cached there yet, or if we
16093 were just reseat()'ed to a new position.
16095 * xdisp.c (set_cursor_from_row): Set start and stop points
16096 according to the row's direction when priming the loop that looks
16097 for the glyph on which to display cursor.
16098 (single_display_spec_intangible_p): Function deleted.
16099 (display_prop_intangible_p): Reimplement to call
16100 handle_display_spec instead of single_display_spec_intangible_p.
16101 Accept 3 additional arguments needed by handle_display_spec.
16102 This fixes incorrect cursor motion across display property with complex
16103 values: lists, `(when COND...)' forms, etc.
16104 (single_display_spec_string_p): Support property values that are
16105 lists with the argument STRING its top-level element.
16106 (display_prop_string_p): Fix the condition for processing a
16107 property that is a list to be consistent with handle_display_spec.
16108 (handle_display_spec): New function, refactored from the
16109 last portion of handle_display_prop.
16110 (compute_display_string_pos): Accept additional argument
16111 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
16112 value of a `display' property is a "replacing spec".
16113 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
16114 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
16115 the display property, but just return a value indicating whether
16116 the display property will replace the characters it covers.
16117 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
16118 frame_window_p members of struct bidi_it.
16119 (compute_display_string_pos, compute_display_string_end):
16121 (push_it): Accept second argument POSITION, where pop_it should
16122 jump to continue iteration.
16123 (reseat_1): Initialize bidi_it.disp_pos.
16125 * keyboard.c (adjust_point_for_property): Adjust the call to
16126 display_prop_intangible_p to its new signature.
16128 * dispextern.h (struct bidi_it): New member frame_window_p.
16129 (bidi_init_it): Update prototypes.
16130 (display_prop_intangible_p): Update prototype.
16131 (compute_display_string_pos, compute_display_string_end):
16132 Declare prototypes.
16133 (struct bidi_it): New members nchars and disp_pos. ch_len is now

16138 Malloc failure behavior now depends on size of allocation.
16139 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
16140 * lisp.h: Change signatures accordingly.
16141 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
16142 All callers changed. (Bug#8762)
16144 * gnutls.c: Use Emacs's memory allocators.
16145 Without this change, the gnutls library would invoke malloc etc.
16146 directly, which causes problems on non-SYNC_INPUT hosts, and which
16147 runs afoul of improving memory_full behavior. (Bug#8761)
16148 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
16149 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
16150 xfree instead of the default malloc, realloc, free.
16151 (Fgnutls_boot): No need to check for memory allocation failure,
16152 since xmalloc does that for us.
16154 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
16155 * category.c (hash_get_category_set):
16156 * ccl.c (ccl_driver):

16168 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
16169 (Fsxhash, Fgethash, Fputhash, Fmaphash):
16170 * image.c (make_image, search_image_cache, lookup_image)
16171 (xpm_put_color_table_h):
16172 * lisp.h (struct Lisp_Hash_Table):
16173 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
16174 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
16175 for hashes and hash indexes, instead of 'unsigned' and 'int'.
16176 * alloc.c (allocate_vectorlike):
16177 Check for overflow in vector size calculations.
16178 * ccl.c (ccl_driver):
16179 Check for overflow when converting EMACS_INT to int.
16180 * fns.c, image.c: Remove unnecessary static decls that would otherwise
16181 need to be updated by these changes.
16182 * fns.c (make_hash_table, maybe_resize_hash_table):
16183 Check for integer overflow with large hash tables.
16184 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
16185 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
16186 (SXHASH_REDUCE): New macro.
16187 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
16188 Use it instead of discarding useful hash info with large hash values.
16189 (sxhash_float): New function.
16190 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
16191 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
16192 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
16193 Rewrite to use FIXNUM_BITS, as this simplifies things.
16194 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
16195 Adjust signatures to match updated version of code.
16196 (consing_since_gc): Now EMACS_INT, since a single hash table can
16197 use more than INT_MAX bytes.
16199 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
16201 Make it possible to build with GCC-4.6+ -O2 -flto.
16203 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
16205 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
16207 * minibuf.c (get_minibuffer, read_minibuf_unwind):
16208 Call minibuffer-inactive-mode.
16210 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
16212 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
16213 Update dependencies.
16215 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
16217 * data.c (init_data): Remove code for UTS, this system is not
16220 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
16222 Don't force ./temacs to start in terminal mode.
16224 * frame.c (make_initial_frame): Initialize faces in all cases, not
16225 only when CANNOT_DUMP is defined.
16226 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
16228 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
16230 * dispnew.c (add_window_display_history): Use const for the string
16231 pointer. Remove declaration, not needed.
16233 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
16235 Use 'inline', not 'INLINE'.
16236 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
16237 * alloc.c, fontset.c (INLINE): Remove.
16238 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
16239 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
16240 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
16241 * gmalloc.c (register_heapinfo): Use inline unconditionally.
16242 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
16244 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
16246 Make it possible to run ./temacs.
16248 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
16249 syms_of_callproc does the same thing. Remove test for
16250 "initialized", do it in the caller.
16251 * emacs.c (main): Avoid calling set_initial_environment when dumping.
16253 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
16255 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
16256 (read_minibuf): Use get_minibuffer.
16257 (syms_of_minibuf): Use DEFSYM.
16258 (Qmetadata): New var.
16259 * data.c (Qbuffer): Don't make it static.
16260 (syms_of_data): Use DEFSYM.
16262 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
16264 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
16265 (CCL_CODE_MIN): New macro.
16267 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
16269 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
16271 * eval.c (Qdebug): Now static.
16272 * lisp.h (Qdebug): Remove decl. This reverts a part of the
16273 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
16274 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
16276 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
16278 * image.c: Various fixes to ImageMagick code comments.
16279 (Fimagemagick_types): Doc fix.
16281 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
16283 Minor fixes prompted by GCC 4.6.0 warnings.
16285 * xselect.c (converted_selections, conversion_fail_tag): Now static.
16287 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
16288 (x_clipboard_manager_save_all): Move extern decl to ...
16289 * xterm.h: ... here, so that it can be checked for consistency.
16291 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
16293 * xselect.c (x_clipboard_manager_save_frame)
16294 (x_clipboard_manager_save_all): New functions.
16295 (Fx_clipboard_manager_save): Lisp function deleted.
16297 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
16298 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
16300 * xterm.h: Update prototype.
16302 2011-05-28 William Xu <william.xwl@gmail.com>
16304 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
16305 exiting (Bug#8239).
16307 2011-05-28 Jim Meyering <meyering@redhat.com>
16309 Avoid a sign-extension bug in crypto_hash_function.
16310 * fns.c (to_uchar): Define.
16311 (crypto_hash_function): Use it to convert some newly-signed
16312 variables to unsigned, to avoid sign-extension bugs. For example,
16313 without this change, (md5 "truc") would evaluate to
16314 45723a2aff78ff4fff7fff1114760e62 rather than the expected
16315 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
16316 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
16318 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
16320 Integer overflow fixes.
16322 * dbusbind.c: Serial number integer overflow fixes.
16323 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
16324 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
16325 to hold a serial number that is too large for a fixnum.
16326 (Fdbus_method_return_internal, Fdbus_method_error_internal):
16327 Check for serial numbers out of range. Decode any serial number
16328 that was so large that it became a float. (Bug#8722)
16330 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
16331 (Fdbus_call_method, Fdbus_call_method_asynchronously):
16332 Use XFASTINT rather than XUINT when numbers are nonnegative.
16333 (xd_append_arg, Fdbus_method_return_internal):
16334 (Fdbus_method_error_internal): Likewise. Also, for unsigned
16335 arguments, check that Lisp number is nonnegative, rather than
16336 silently wrapping negative numbers around. (Bug#8722)
16337 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
16340 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
16342 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
16344 ccl: Add integer overflow checks.
16345 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
16346 (IN_INT_RANGE): New macros.
16347 (ccl_driver): Use them to check for integer overflow when
16348 decoding a CCL program. Many of the new checks are whether XINT (x)
16349 fits in int; it doesn't always, on 64-bit hosts. The new version
16350 doesn't catch all possible integer overflows, but it's an
16351 improvement. (Bug#8719)
16353 * alloc.c (make_event_array): Use XINT, not XUINT.
16354 There's no need for unsigned here.
16356 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
16357 This follows up to the 2011-05-06 change that substituted uintptr_t
16358 for EMACS_INT. This case wasn't caught back then.
16360 Rework Fformat to avoid integer overflow issues.
16361 * editfns.c: Include <float.h> unconditionally, as it's everywhere
16362 now (part of C89). Include <verify.h>.
16363 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
16364 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
16365 (Fformat): Avoid the prepass trying to compute sizes; it was only
16366 approximate and thus did not catch overflow reliably. Instead, walk
16367 through the format just once, formatting and computing sizes as we go,
16368 checking for integer overflow at every step, and allocating a larger
16369 buffer as needed. Keep track separately whether the format is
16370 multibyte. Keep only the most-recently calculated precision, rather
16371 than them all. Record whether each argument has been converted to
16372 string. Use EMACS_INT, not int, for byte and char and arg counts.
16373 Support field widths and precisions larger than INT_MAX. Avoid
16374 sprintf's undefined behavior with conversion specifications such as %#d
16375 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
16376 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
16377 formatting out-of-range floating point numbers with int
16378 formats. (Bug#8668)
16380 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
16382 * data.c: Avoid integer truncation in expressions involving floats.
16383 * data.c: Include <intprops.h>.
16384 (arith_driver): When there's an integer overflow in an expression
16385 involving floating point, convert the integers to floating point
16386 so that the resulting value does not suffer from catastrophic
16387 integer truncation. For example, on a 64-bit host (* 4
16388 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
16389 Do not rely on undefined behavior after integer overflow.
16391 merge count_size_as_multibyte, parse_str_to_multibyte
16392 * character.c, character.h (count_size_as_multibyte):
16393 Rename from parse_str_to_multibyte; all uses changed.
16394 Check for integer overflow.
16395 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
16396 since it's now a duplicate of the other. This is more of
16397 a character than a buffer op, so better that it's in character.c.
16398 * fns.c, print.c: Adjust to above changes.
16400 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
16402 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
16404 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
16406 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
16407 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
16408 (x_clipboard_manager_save): Now static.
16409 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
16411 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
16412 (crypto_hash_function): Now static.
16413 Fix pointer signedness problems. Avoid unnecessary initializations.
16415 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
16417 * termhooks.h (Vselection_alist): Make it terminal-local.
16419 * terminal.c (create_terminal): Initialize it.
16421 * xselect.c: Support for clipboard managers.
16422 (Vselection_alist): Move to termhooks.h as terminal-local var.
16423 (LOCAL_SELECTION): New macro.
16424 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
16425 (symbol_to_x_atom): Remove gratuitous arg.
16426 (x_handle_selection_request, lisp_data_to_selection_data)
16427 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
16428 (x_own_selection, x_get_local_selection, x_convert_selection):
16429 New arg, specifying work frame. Use terminal-local Vselection_alist.
16430 (some_frame_on_display): Delete unused function.
16431 (Fx_own_selection_internal, Fx_get_selection_internal)
16432 (Fx_disown_selection_internal, Fx_selection_owner_p)
16433 (Fx_selection_exists_p): New optional frame arg.
16434 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
16435 (x_handle_selection_clear): Don't treat other terminals with the
16436 same keyboard specially. Use the terminal-local Vselection_alist.
16437 (x_clear_frame_selections): Use Frun_hook_with_args.
16439 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
16441 * xterm.h: Add support for those atoms.
16443 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
16445 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
16446 (converted_selections, conversion_fail_tag): New global variables.
16447 (x_selection_request_lisp_error): Free the above.
16448 (x_get_local_selection): Remove unnecessary code.
16449 (x_reply_selection_request): Args changed; handle arbitrary array
16450 of converted selections stored in converted_selections.
16451 Separate the XChangeProperty and SelectionNotify steps.
16452 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
16453 (x_convert_selection): New function.
16454 (x_handle_selection_event): Simplify.
16455 (x_get_foreign_selection): Don't ignore incoming requests while
16456 waiting for an answer; this will fail when we implement
16457 SAVE_TARGETS, and seems unnecessary anyway.
16458 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
16459 (Vx_sent_selection_functions): Doc fix.
16461 2011-05-26 Leo Liu <sdl.web@gmail.com>
16463 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
16465 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16467 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
16469 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
16470 for fringe update if it has periodic bitmap.
16471 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
16472 and fringe_bitmap_periodic_p.
16474 * fringe.c (get_fringe_bitmap_data): New function.
16475 (draw_fringe_bitmap_1, update_window_fringes): Use it.
16476 (update_window_fringes): Record periodicity of fringe bitmap in glyph
16477 row. Mark glyph row for fringe update if periodicity changed.
16479 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
16480 for fringe update unless it has periodic bitmap.
16482 2011-05-25 Kenichi Handa <handa@m17n.org>
16484 * xdisp.c (get_next_display_element): Set correct it->face_id for
16485 a static composition.
16487 2011-05-24 Leo Liu <sdl.web@gmail.com>
16490 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
16492 * fns.c (crypto_hash_function, Fsha1): New function.
16493 (Fmd5): Use crypto_hash_function.
16494 (syms_of_fns): Add Ssha1.
16496 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
16498 * gnutls.c: Remove unused macros.
16499 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
16500 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
16501 Remove macros that are defined and never used.
16502 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
16504 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
16506 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
16507 (Fx_get_selection_internal): Minor cleanup.
16508 (Fx_own_selection_internal): Rename arguments for consistency with
16511 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
16513 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
16515 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
16517 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
16519 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16521 * dispnew.c (scrolling_window): Don't exclude the case that the
16522 last enabled row in the desired matrix touches the bottom boundary.
16524 2011-05-21 Glenn Morris <rgm@gnu.org>
16526 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
16527 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
16528 and add some more files.
16530 2011-05-20 Eli Zaretskii <eliz@gnu.org>
16532 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
16533 report_file_error introduced by the change from 2011-05-07.
16535 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
16537 * systime.h (Time): Define only if emacs is defined.
16538 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
16539 where the include path doesn't have X11/X.h by default. See
16540 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
16542 2011-05-20 Kenichi Handa <handa@m17n.org>
16544 * composite.c (find_automatic_composition): Fix previous change.
16546 2011-05-20 Glenn Morris <rgm@gnu.org>
16548 * lisp.mk: New file, split from Makefile.in.
16549 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
16550 (shortlisp): Remove.
16551 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
16553 2011-05-19 Glenn Morris <rgm@gnu.org>
16555 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
16556 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
16557 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
16558 (lisp): Set the order to that of loadup.el.
16559 (shortlisp): Make it a copy of $lisp.
16560 (SOME_MACHINE_LISP): Remove.
16561 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
16562 Use just $shortlisp, not $SOME_MACHINE_LISP too.
16564 2011-05-18 Kenichi Handa <handa@m17n.org>
16566 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
16567 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
16568 (find_automatic_composition): Mostly rewrite for efficiency.
16570 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
16572 * makefile.w32-in: Update dependencies.
16574 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
16576 * menu.c: Include limits.h (fixes the MS-Windows build broken by
16577 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
16579 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
16581 Fix some integer overflow issues, such as string length overflow.
16583 * insdel.c (count_size_as_multibyte): Check for string overflow.
16585 * character.c (lisp_string_width): Check for string overflow.
16586 Use EMACS_INT, not int, for string indexes and lengths; in
16587 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
16588 the resulting string length overflows an EMACS_INT; instead,
16589 report a string overflow if no precision given. When checking for
16590 precision exhaustion, use a check that cannot possibly have
16591 integer overflow. (Bug#8675)
16592 * character.h (lisp_string_width): Adjust to new signature.
16594 * alloc.c (string_overflow): New function.
16595 (Fmake_string): Use it. This doesn't change behavior, but saves
16596 a few bytes and will simplify future changes.
16597 * character.c (string_escape_byte8): Likewise.
16598 * lisp.h (string_overflow): New decl.
16600 Fixups, following up to the user-interface timestamp change.
16601 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
16602 for UI timestamps, instead of unsigned long.
16603 * msdos.c (mouse_get_pos): Likewise.
16604 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
16605 * w32gui.h (Time): Define by including "systime.h" rather than by
16606 declaring it ourselves. (Bug#8664)
16608 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
16609 * image.c (clear_image_cache): Likewise.
16611 * term.c (term_mouse_position): Don't assume time_t wraparound.
16613 Be more systematic about user-interface timestamps.
16614 Before, the code sometimes used 'Time', sometimes 'unsigned long',
16615 and sometimes 'EMACS_UINT', to represent these timestamps.
16616 This change causes it to use 'Time' uniformly, as that's what X uses.
16617 This makes the code easier to follow, and makes it easier to catch
16618 integer overflow bugs such as Bug#8664.
16619 * frame.c (Fmouse_position, Fmouse_pixel_position):
16620 Use Time, not unsigned long, for user-interface timestamps.
16621 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
16622 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
16623 * keyboard.h (last_event_timestamp): Likewise.
16624 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
16625 * menu.h (xmenu_show): Likewise.
16626 * term.c (term_mouse_position): Likewise.
16627 * termhooks.h (struct input_event.timestamp): Likewise.
16628 (struct terminal.mouse_position_hook): Likewise.
16629 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
16630 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
16631 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
16632 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
16633 what it was before.
16634 * menu.h, termhooks.h: Include "systime.h", for Time.
16636 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
16637 Don't assume that the difference between two unsigned long values
16638 can fit into an integer. At this point, we know button_down_time
16639 <= event->timestamp, so the difference must be nonnegative, so
16640 there's no need to cast the result if double-click-time is
16641 nonnegative, as it should be; check that it's nonnegative, just in
16642 case. This bug is triggered when events are more than 2**31 ms
16643 apart (about 25 days). (Bug#8664)
16645 * xselect.c (last_event_timestamp): Remove duplicate decl.
16646 (x_own_selection): Remove needless cast to unsigned long.
16648 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
16649 that always fit in int. Use a sentinel instead of a counter, to
16650 avoid a temp and to allay GCC's concerns about possible int overflow.
16651 * frame.h (struct frame): Use int for menu_bar_items_used
16652 instead of EMACS_INT, since it always fits in int.
16654 * menu.c (grow_menu_items): Check for int overflow.
16656 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
16658 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
16659 Before, the code was not consistent. These values cannot exceed
16660 2**31 - 1 so there's no need to make them unsigned.
16661 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
16662 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
16663 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
16665 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
16667 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
16668 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
16669 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
16670 presumably because the widths might not match.
16672 * window.c (size_window): Avoid needless test at loop start.
16674 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
16676 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
16678 2011-05-12 Drew Adams <drew.adams@oracle.com>
16680 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
16682 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16684 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
16685 `width' to `bar_area_x' and `bar_area_width', respectively.
16686 (x_scroll_run): Take account of fringe background extension.
16688 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
16689 Rename local vars `left' and `width' to `bar_area_x' and
16690 `bar_area_width', respectively.
16691 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
16692 background extension.
16694 2011-05-10 Jim Meyering <meyering@redhat.com>
16696 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
16698 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
16700 * image.c (Finit_image_library): Return t for built-in image types,
16701 like pbm and xbm. (Bug#8640)
16703 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
16705 * w32menu.c (set_frame_menubar): Fix submenu allocation.
16707 2011-05-07 Eli Zaretskii <eliz@gnu.org>
16709 * w32console.c (Fset_screen_color): Doc fix.
16710 (Fget_screen_color): New function.
16711 (syms_of_ntterm): Defsubr it.
16713 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
16714 unlink the temporary file if Fcall_process didn't create it in the
16716 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
16717 child process will be redirected to a file specified with `:file'.
16718 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
16719 cue to call_process_cleanup not to close that handle.
16721 2011-05-07 Ben Key <bkey76@gmail.com>
16723 * makefile.w32-in: The bootstrap-temacs rule now makes use of
16724 one of two shell specific rules, either bootstrap-temacs-CMD or
16725 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
16726 to the previous implementation of the bootstrap-temacs rule.
16727 The bootstrap-temacs-CMD rule is similar to the previous
16728 implementation of the bootstrap-temacs rule except that it
16729 makes use of the ESC_CFLAGS variable instead of the CFLAGS
16732 These changes, along with some changes to nt/configure.bat,
16733 nt/gmake.defs, and nt/nmake.defs, are required to extend my
16734 earlier fix to add support for --cflags and --ldflags options
16735 that include quotes so that it works whether make uses cmd or
16738 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
16740 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
16741 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
16743 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
16744 a string. Handle both cases.
16745 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
16746 (Fdbus_register_method): Use Qinvalid_function.
16748 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
16750 * makefile.w32-in: Update dependencies.
16751 (LISP_H): Add inttypes.h and stdin.h.
16752 (PROCESS_H): Add unistd.h.
16754 2011-05-06 Eli Zaretskii <eliz@gnu.org>
16756 * lread.c: Include limits.h (fixes the MS-Windows build broken by
16757 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
16759 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
16761 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
16763 * term.c (vfatal): Remove stray call to va_end.
16764 It's not needed and the C Standard doesn't allow it here anyway.
16766 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
16767 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
16769 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
16772 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
16774 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16776 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
16778 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
16780 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
16782 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
16783 * charset.c (Fdefine_charset_internal): Don't initialize
16784 charset.code_space[15]. The value was garbage, on hosts with
16785 32-bit int (Bug#8600).
16787 * lread.c (read_integer): Be more consistent with string-to-number.
16788 Use string_to_number to do the actual conversion; this avoids
16789 rounding errors and fixes some other screwups. Without this fix,
16790 for example, #x1fffffffffffffff was misread as -2305843009213693952.
16791 (digit_to_number): Move earlier, for benefit of read_integer.
16792 Return -1 if the digit is out of range for the base, -2 if it is
16793 not a digit in any supported base. (Bug#8602)
16795 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
16797 * dispnew.c (scrolling_window): Return 1 if we scrolled,
16798 to match comment at start of function. This also removes a
16799 GCC warning about overflow in a 32+64-bit port.
16801 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
16803 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
16804 Reported by Stefan Monnier in
16805 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
16806 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
16807 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
16809 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
16810 (EMACS_UINTPTR): Likewise, with uintptr_t.
16812 * lisp.h: Prefer 64-bit EMACS_INT if available.
16813 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
16814 on 32-bit hosts that have 64-bit int, so that they can access
16816 However, temporarily disable this change unless the temporary
16817 symbol WIDE_EMACS_INT is defined.
16819 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
16821 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
16822 This removes an assumption that EMACS_INT and long are the same
16823 width as pointers. The assumption is true for Emacs porting targets
16824 now, but we want to make other targets possible.
16825 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
16826 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
16827 In the rest of the code, change types of integers that hold casted
16828 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
16829 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
16830 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
16831 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
16832 No need to cast type when ORing.
16833 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
16834 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
16835 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
16836 assume EMACS_INT is the same width as char *.
16837 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
16838 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
16839 Remove no-longer-needed casts.
16840 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
16841 (xg_tool_bar_help_callback, xg_make_tool_item):
16842 Use EMACS_INTPTR to hold an integer
16843 that will be cast to void *; this can avoid a GCC warning
16844 if EMACS_INT is not the same width as void *.
16845 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
16846 * xdisp.c (display_echo_area_1, resize_mini_window_1):
16847 (current_message_1, set_message_1):
16848 Use a local to convert to proper width without a cast.
16849 * xmenu.c (dialog_selection_callback): Likewise.
16851 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
16852 Also, don't assume VALBITS / RAND_BITS is less than 5,
16853 and don't rely on undefined behavior when shifting a 1 left into
16855 * lisp.h (get_random): Change signature to match.
16857 * lread.c (hash_string): Use size_t, not int, for hash computation.
16858 Normally we prefer signed values; but hashing is special, because
16859 it's better to use unsigned division on hash table sizes so that
16860 the remainder is nonnegative. Also, size_t is the natural width
16861 for hashing into memory. The previous code used 'int', which doesn't
16862 retain enough info to hash well into very large tables.
16863 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
16865 * dbusbind.c: Don't possibly lose pointer info when converting.
16866 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
16867 Use XPNTR rather than XHASH, so that the high-order bits of
16868 the pointer aren't lost when converting through void *.
16870 * eval.c (Fautoload): Don't double-shift a pointer.
16872 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
16874 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
16876 * gnutls.c (DEF_GNUTLS_FN):
16877 * image.c (DEF_IMGLIB_FN): Make function pointers static.
16879 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
16881 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
16884 2011-05-05 Eli Zaretskii <eliz@gnu.org>
16886 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
16887 New version that can reserve upto 2GB of heap space.
16889 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
16891 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
16893 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
16895 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
16896 `gnutls_certificate_set_x509_key_file'.
16898 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
16900 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
16901 Update dependencies.
16903 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
16905 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
16906 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
16907 Remove unused parameter `fildes'.
16908 * process.c (read_process_output, send_process): Don't pass it.
16910 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
16912 Fix previous change: the library cache is defined in w32.c.
16913 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
16914 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
16916 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
16918 Implement dynamic loading of GnuTLS on Windows.

16955 * process.c: Include lisp.h before w32.h, not after.
16956 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
16957 instead of gnutls_record_check_pending.
16959 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
16961 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
16963 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options

17009 rather than `XVECTOR (FOO)->size'.
17011 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
17012 inttypes.h, as a gnulib replacement is used if it not available in

17040 produced by %s or %c overflows available buffer space. (Bug#8545)
17042 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
17044 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

17047 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
17049 * w32.c (init_environment): Warn about defaulting HOME to C:\.
17051 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
17053 * keyboard.c (Qdelayed_warnings_hook): Define.
17054 (command_loop_1): Run `delayed-warnings-hook'
17055 if Vdelayed_warnings_list is non-nil.
17056 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
17057 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.

17061 * doprnt.c (doprnt): Don't return value smaller than the buffer
17062 size if the message was truncated. (Bug#8545).

17066 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

17079 Improve `doprnt' and its usage. (Bug#8545)
17080 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
17081 `format_end'. Remove support for %l as a conversion specifier.
17082 Don't use xrealloc. Improve diagnostics when the %l size modifier
17083 is used. Update the commentary.
17085 * eval.c (verror): Simplify calculation of size_t.
17087 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
17090 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
17092 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
17095 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
17097 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
17098 This makes this file independent of the recent pseudovector change.
17100 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
17102 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
17104 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
17105 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
17106 Remove unused local.
17107 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
17109 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
17110 GCC 4.6.0 optimizes based on type-based alias analysis.
17111 For example, if b is of type struct buffer * and v of type struct
17112 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
17113 != &v->size, and therefore "v->size = 1; b->size = 2; return
17114 v->size;" must therefore return 1. This assumption is incorrect
17115 for Emacs, since it type-puns struct Lisp_Vector * with many other
17116 types. To fix this problem, this patch adds a new type struct
17117 vectorlike_header that documents the constraints on layout of vectors
17118 and pseudovectors, and helps optimizing compilers not get fooled
17119 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
17120 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
17121 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
17123 (XSETPVECTYPE): Rewrite in terms of new macro.
17124 (XSETPVECTYPESIZE): New macro, specifying both type and size.
17125 This is a bit clearer, and further avoids the possibility of
17126 undesirable aliasing.
17127 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
17128 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
17129 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
17130 since Lisp_Subr is a special case (no "next" field).
17131 (ASIZE): Now uses header.size rather than size.
17132 All previous uses of XVECTOR (foo)->size replaced to use this macro,
17133 to avoid the hassle of writing XVECTOR (foo)->header.size.
17134 (struct vectorlike_header): New type.
17135 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
17136 object, to help avoid aliasing.
17137 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
17138 (SUBRP): Likewise, since Lisp_Subr is a special case.
17139 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
17140 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
17141 (struct Lisp_Hash_Table): Combine first two members into a single
17142 struct vectorlike_header member. All uses of "size" and "next" members
17143 changed to be "header.size" and "header.next".
17144 * buffer.h (struct buffer): Likewise.
17145 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
17146 * frame.h (struct frame): Likewise.
17147 * process.h (struct Lisp_Process): Likewise.
17148 * termhooks.h (struct terminal): Likewise.
17149 * window.c (struct save_window_data, struct saved_window): Likewise.
17150 * window.h (struct window): Likewise.
17151 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
17152 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
17153 * buffer.c (init_buffer_once): Likewise.
17154 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
17156 * process.c (Fformat_network_address): Use local var for size,
17159 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
17161 Make the Lisp reader and string-to-float more consistent (Bug#8525)
17162 * data.c (atof): Remove decl; no longer used or needed.
17163 (digit_to_number): Move to lread.c.
17164 (Fstring_to_number): Use new string_to_number function, to be
17165 consistent with how the Lisp reader treats infinities and NaNs.
17166 Do not assume that floating-point numbers represent EMACS_INT
17167 without losing information; this is not true on most 64-bit hosts.
17168 Avoid double-rounding errors, by insisting on integers when
17169 parsing non-base-10 numbers, as the documentation specifies.
17170 * lisp.h (string_to_number): New decl, replacing ...
17171 (isfloat_string): Remove.
17172 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
17173 (read1): Do not accept +. and -. as integers; this
17174 appears to have been a coding error. Similarly, do not accept
17175 strings like +-1e0 as floating point numbers. Do not report
17176 overflow for integer overflows unless the base is not 10 which
17177 means we have no simple and reliable way to continue.
17178 Break out the floating-point parsing into a new
17179 function string_to_number, so that Fstring_to_number parses
17180 floating point numbers consistently with the Lisp reader.
17181 (digit_to_number): Move here from data.c. Make it static inline.
17182 (E_CHAR, EXP_INT): Remove, replacing with ...
17183 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
17184 (string_to_number): New function, replacing isfloat_string.
17185 This function checks for valid syntax and produces the resulting
17186 Lisp float number too. Rework it so that string-to-number
17187 no longer mishandles examples like "1.0e+". Use strtoumax,
17188 so that overflow for non-base-10 numbers is reported only when
17189 there's no portable and simple way to convert to floating point.
17191 * textprop.c (set_text_properties_1): Rewrite for clarity,
17192 and to avoid GCC warning about integer overflow.
17194 * intervals.h (struct interval): Use EMACS_INT for members
17195 where EMACS_UINT might cause problems. See
17196 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
17197 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
17198 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
17200 (offset_intervals): Tell GCC not to worry about length overflow
17201 when negating a negative length.
17203 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
17204 (overrun_check_free): Likewise.
17206 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
17207 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
17210 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
17211 (gnutls_make_error): Rename local to avoid shadowing.
17212 (gnutls_emacs_global_deinit): ifdef out; not used.
17213 (Fgnutls_boot): Use const for pointer to readonly storage.
17214 Comment out unused local. Fix pointer signedness problems.
17216 * lread.c (openp): Don't stuff size_t into an 'int'.
17217 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
17218 about possible signed overflow.
17220 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
17221 (GDK_KEY_g): Don't define if already defined.
17222 (xg_prepare_tooltip): Avoid pointer signedness problem.
17223 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
17225 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
17226 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
17228 * xfns.c (Fx_window_property): Simplify a bit,
17229 to make a bit faster and to avoid GCC 4.6.0 warning.
17230 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
17232 * fns.c (internal_equal): Don't assume size_t fits in int.
17234 * alloc.c (compact_small_strings): Tighten assertion a little.
17236 Replace pEd with more-general pI, and fix some printf arg casts.
17237 * lisp.h (pI): New macro, generalizing old pEd macro to other
17238 conversion specifiers. For example, use "...%"pI"d..." rather
17239 than "...%"pEd"...".
17240 (pEd): Remove. All uses replaced with similar uses of pI.
17241 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
17242 * alloc.c (check_pure_size): Don't overflow by converting size to int.
17243 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
17244 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
17245 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
17246 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
17247 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
17249 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
17250 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
17251 * print.c (safe_debug_print, print_object): Likewise.
17252 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
17254 Use pI instead of if-then-else-abort. Use %p to avoid casts,
17255 avoiding the 0 flag, which is not portable.
17256 * process.c (Fmake_network_process): Use pI to avoid cast.
17257 * region-cache.c (pp_cache): Likewise.
17258 * xdisp.c (decode_mode_spec): Likewise.
17259 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
17260 behavior on 64-bit hosts with printf arg.
17261 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
17262 (x_stop_queuing_selection_requests): Likewise.
17263 (x_get_window_property): Don't truncate byte count to an 'int'
17266 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
17267 here, since it parses constructs like leading '-' and spaces,
17268 which are not wanted; and it overflows with large numbers.
17269 Instead, simply match F[0-9]+, which is what is wanted anyway.
17271 * alloc.c: Remove unportable assumptions about struct layout.
17272 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
17273 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
17274 (allocate_vectorlike, make_pure_vector): Use the new macros,
17275 plus offsetof, to remove unportable assumptions about struct layout.
17276 These assumptions hold on all porting targets that I know of, but
17277 they are not guaranteed, they're easy to remove, and removing them
17278 makes further changes easier.
17280 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
17281 This doesn't fix a bug but makes the code clearer.
17282 (string_overrun_cookie): Now const. Use initializers that
17283 don't formally overflow signed char, to avoid warnings.
17284 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
17285 can cause Emacs to crash when string overrun checking is enabled.
17286 (allocate_buffer): Don't assume sizeof (struct buffer) is a
17287 multiple of sizeof (EMACS_INT); it need not be, if
17288 alignof(EMACS_INT) < sizeof (EMACS_INT).
17289 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
17291 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
17293 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
17295 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
17297 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
17298 supposed to be handshaking. (Bug#8556)
17299 Reported by Paul Eggert <eggert@cs.ucla.edu>.
17301 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
17303 * lisp.h (Qdebug): List symbol.
17304 * eval.c (Qdebug): Restore global linkage.
17305 * keyboard.c (debug-on-event): New variable.
17306 (handle_user_signal): Break into debugger when debug-on-event
17307 matches the current signal symbol.
17309 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
17311 * alloc.c (check_sblock, check_string_bytes)
17312 (check_string_free_list): Convert to standard C.
17314 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
17316 * w32.c (emacs_gnutls_push): Fix typo.
17318 2011-04-25 Eli Zaretskii <eliz@gnu.org>
17320 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
17321 "cast to pointer from integer of different size".
17323 Improve doprnt and its use in verror. (Bug#8545)
17324 * doprnt.c (doprnt): Document the set of format control sequences
17325 supported by the function. Use SAFE_ALLOCA instead of always
17328 * eval.c (verror): Don't limit the buffer size at size_max-1, that
17329 is one byte too soon. Don't use xrealloc; instead xfree and
17332 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
17334 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
17337 * gnutls.c: Renamed global_initialized to
17338 gnutls_global_initialized. Added internals for the
17339 :verify-hostname-error, :verify-error, and :verify-flags
17340 parameters of `gnutls-boot' and documented those parameters in the

17824 * xdisp.c (redisplay_window): Simplify code, to make it more
17825 obvious that ignore_mouse_drag_p is not accessed if !defined
17826 USE_GTK && !defined HAVE_NS.
17828 * intervals.c: Make symbols static if they're not exported.

17831 * intervals.h (merge_interval_right, delete_interval): Remove decls.
17833 * insdel.c: Make symbols static if they're not exported.
17834 However, leave prepare_to_modify_buffer alone. It's never
17835 called from outside this function, but that appears to be a bug.
17836 (combine_after_change_list, combine_after_change_buffer):
17837 (adjust_after_replace, signal_before_change): Now static.
17838 (adjust_after_replace_noundo): Remove; unused.

17866 * font.c (font_close_object): Now static.
17867 * font.h (font_close_object): Remove.
17868 * fontset.c (FONTSET_OBJLIST): Remove.
17869 (free_realized_fontset) #if-0 the body, which does nothing.
17870 (face_suitable_for_char_p): #if-0, as it's never called.
17871 * fontset.h (face_suitable_for_char_p): Remove decl.
17872 * xfaces.c (face_at_string_position):
17873 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,
17874 since 0 is always ASCII.
17876 * fns.c (weak_hash_tables): Now static.
17878 * fileio.c: Make symbols static if they're not exported.
17879 (auto_saving, auto_save_mode_bits, auto_save_error_occurred):

17897 * editfns.c, lisp.h (get_operating_system_release): Remove.
17898 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
17899 worth the hassle of breaking this out.
17901 * xterm.c: Make symbols static if they're not exported.
17902 (x_raise_frame, x_lower_frame, x_wm_set_window_state):

18005 * buffer.c (buffer_count): Remove unused var.

18009 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
18010 * dispextern.h (bidi_dump_cached_states): Remove, since it's
18011 exported only to the debugger.

18014 * atimer.h (run_all_atimers): Remove; not exported.
18016 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
18017 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
18018 was inaccessible from Lisp.
18019 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
18020 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
18022 alloc.c: Import and export fewer symbols, and remove unused items.
18023 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
18025 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
18026 it's not optimized away by whole-program optimization.
18027 (message_enable_multibyte, free_misc): Remove.
18028 (catchlist, handlerlist, mark_backtrace):
18029 Declare only if BYTE_MARK_STACK.

18038 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
18039 (mark_backtrace): Define only if BYTE_MARK_STACK.
18040 * xdisp.c (message_enable_multibyte): Now static.
18042 Declare Lisp_Object Q* variables to be 'static' if not exported.
18043 This makes it easier for human readers (and static analyzers)
18044 to see whether these variables are used from other modules.
18045 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
18046 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
18047 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

18055 Remove decls of unexported vars.
18056 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
18058 * lisp.h (DEFINE_FUNC): Make sname 'static'.
18060 Make Emacs functions such as Fatom 'static' by default.
18061 This makes it easier for human readers (and static analyzers)
18062 to see whether these functions can be called from other modules.
18063 DEFUN now defines a static function. To make the function external
18064 so that it can be used in other C modules, use the new macro DEFUE.
18065 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
18066 (Finit_image_library):
18067 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
18068 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
18069 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
18070 Remove decls, since these functions are now static.
18071 (Funintern, Fget_internal_run_time): New decls, since these functions
18072 were already external.
18074 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
18075 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

18081 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
18082 Mark functions with DEFUE instead of DEFUN,
18083 if they are used in other modules.
18084 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
18085 decls for now-static functions.
18086 * buffer.h (Fdelete_overlay): Remove decl.
18087 * callproc.c (Fgetenv_internal): Mark as internal.
18088 * composite.c (Fremove_list_of_text_properties): Remove decl.

18095 * fileio.c (Fmake_symbolic_link): New forward static decl.
18096 * image.c (Finit_image_library): New forward static decl.
18097 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
18098 * intervals.h (Fprevious_property_change):
18099 (Fremove_list_of_text_properties): Remove decls.
18100 * keyboard.c (Fthis_command_keys): Remove decl.
18101 (Fcommand_execute): New forward static decl.

18117 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
18119 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
18122 2011-04-13 Eli Zaretskii <eliz@gnu.org>
18124 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
18125 when at ZV. (Bug#8487)
18127 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
18129 * charset.c (Fclear_charset_maps): Use xfree instead of free.
18131 * keyboard.c (parse_tool_bar_item): Likewise.
18132 * sound.c (sound_cleanup, alsa_close): Likewise.
18133 * termcap.c (tgetent): Likewise.
18134 * xfns.c (x_default_font_parameter): Likewise.
18135 * xsettings.c (read_and_apply_settings): Likewise.
18137 * alloc.c (overrun_check_malloc, overrun_check_realloc)
18138 (overrun_check_free): Protoize.
18140 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
18142 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
18143 since callers should never pass a negative size.
18144 Change the signature to match that of plain 'read' and 'write'; see
18145 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
18146 * lisp.h: Update prototypes of emacs_write and emacs_read.
18148 2011-04-11 Eli Zaretskii <eliz@gnu.org>
18150 * xdisp.c (redisplay_window): Don't try to determine the character
18151 position of the scroll margin if the window start point w->startp
18152 is outside the buffer's accessible region. (Bug#8468)
18154 2011-04-10 Eli Zaretskii <eliz@gnu.org>
18156 Fix write-region and its subroutines for buffers > 2GB.
18157 * fileio.c (a_write, e_write): Modify declaration of arguments and
18158 local variables to support buffers larger than 2GB.
18159 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
18161 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
18162 argument, local variables, and return value.
18164 * lisp.h: Update prototypes of emacs_write and emacs_read.
18166 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
18168 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
18170 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
18172 Fix more problems found by GCC 4.6.0's static checks.
18174 * xdisp.c (vmessage): Use a better test for character truncation.
18176 * charset.c (load_charset_map): <, not <=, for optimization,
18177 and to avoid potential problems with integer overflow.
18178 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
18179 * casetab.c (set_identity, shuffle): Likewise.
18180 * editfns.c (Fformat): Likewise.
18181 * syntax.c (skip_chars): Likewise.
18183 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
18184 This also lets GCC 4.6.0 generate slightly better loop code.
18186 * callint.c (Fcall_interactively): <, not <=, for optimization.
18187 (Fcall_interactively): Count the number of arguments produced,
18188 not the number of arguments given. This is simpler and lets GCC
18189 4.6.0 generate slightly better code.
18191 * ftfont.c: Distingish more carefully between FcChar8 and char.
18192 The previous code passed unsigned char * to a functions like
18193 strlen and xstrcasecmp that expect char *, which does not
18194 conform to the C standard.
18195 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
18196 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
18197 char * when the C standard requires it.
18199 * keyboard.c (read_char): Remove unused var.
18201 * eval.c: Port to Windows vsnprintf (Bug#8435).
18202 Include <limits.h>.
18203 (SIZE_MAX): Define if the headers do not.
18204 (verror): Do not give up if vsnprintf returns a negative count.
18205 Instead, grow the buffer. This ports to Windows vsnprintf, which
18206 does not conform to C99. Problem reported by Eli Zaretskii.
18207 Also, simplify the allocation scheme, by avoiding the need for
18208 calling realloc, and removing the ALLOCATED variable.
18210 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
18212 Remove invocations of doprnt, as Emacs now uses vsnprintf.
18213 But keep the doprint source code for now, as we might revamp it
18214 and use it again (Bug#8435).
18215 * lisp.h (doprnt): Remove.
18216 * Makefile.in (base_obj): Remove doprnt.o.
18217 * deps.mk (doprnt.o): Remove.
18219 error: Print 32- and 64-bit integers portably (Bug#8435).
18220 Without this change, on typical 64-bit hosts error ("...%d...", N)
18221 was used to print both 32- and 64-bit integers N, which relied on
18222 undefined behavior.
18223 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
18224 * lisp.h (error, verror): Mark as printf-like functions.
18225 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.

18375 This avoids several warnings with gcc -Wstrict-overflow.
18376 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
18377 directly, rather than having caller test rule sign. This avoids
18378 some unnecessary tests.
18379 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
18380 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
18381 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
18383 * xfont.c (xfont_text_extents): Remove var that was set but not used.
18384 (xfont_open): Avoid unnecessary tests.
18386 * composite.c (composition_gstring_put_cache): Use unsigned integer.

18398 since the condition is always true at first.
18400 * intervals.c (graft_intervals_into_buffer): Mark var as used.

18431 * eval.c (funcall_lambda): Rename local to avoid shadowing.
18433 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
18434 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
18435 can always succeed if overflow has undefined behavior.
18437 * search.c (boyer_moore, wordify): Remove vars set but not used.
18438 (wordify): Omit three unnecessary tests.
18440 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

18452 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
18453 Check for integer overflow on size calculations.
18455 * buffer.c (Fprevious_overlay_change): Remove var that is set
18458 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
18459 Remove vars that are set but not used.
18460 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.

18468 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
18469 that are set but not used.
18471 * xfns.c (make_invisible_cursor): Don't return garbage
18472 if XCreateBitmapFromData fails (Bug#8410).
18474 * xselect.c (x_get_local_selection, x_handle_property_notify):
18475 Remove vars that are set but not used.
18477 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
18478 (make_invisible_cursor): Initialize a possibly-uninitialized variable.

18481 Remove var that is set but not used.
18482 (scroll_bar_windows_size): Now size_t, not int.
18483 (x_send_scroll_bar_event): Use size_t, not int, for sizes.

18495 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
18496 (decode_coding_charset): Remove vars that are set but not used.
18498 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
18499 that is set but not used.
18501 * print.c (print_object): Remove var that is set but not used.
18503 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
18504 The gnulib version avoids calling malloc in the usual case,
18505 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
18506 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
18507 * filelock.c (current_lock_owner): Likewise.
18508 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
18509 * sysdep.c: Include allocator.h, careadlinkat.h.
18510 (emacs_no_realloc_allocator): New static constant.
18511 (emacs_readlink): New function.
18512 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
18513 ../lib/careadlinkat.h.
18515 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
18517 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
18518 first non-nil return value).

18534 (get_per_char_metric): Remove parameter `f', unused since
18535 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

18579 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
18580 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
18581 (FletX, Flet): Obey lexical binding.
18582 (Fcommandp): Handle closures.
18583 (Feval): New `lexical' arg.
18584 (eval_sub): New function extracted from Feval. Use it almost
18585 everywhere where Feval was used. Look up vars in lexical env.
18587 (Ffunctionp): Move from subr.el.
18588 (Ffuncall): Handle closures.
18589 (apply_lambda): Remove `eval_flags'.
18590 (funcall_lambda): Handle closures and new byte-code-functions.
18591 (Fspecial_variable_p): New function.
18592 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,

18595 * doc.c (Fdocumentation, store_function_docstring):
18596 * data.c (Finteractive_form): Handle closures.
18598 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
18601 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
18603 (exec_byte_code): New function extracted from Fbyte_code to handle new
18604 calling convention for byte-code-functions. Add new byte-codes.

18619 (redisplay_window): Even when falling back on "recentering",
18620 position point in the window according to scroll-conservatively,
18621 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
18623 (try_scrolling): When point is above the window, allow searching
18624 as far as scroll_max, or one screenful, to compute vertical
18625 distance from PT to the scroll margin position. This prevents
18626 try_scrolling from unnecessarily failing when
18627 scroll-conservatively is set to a value slightly larger than the
18628 window height. Clean up the case of PT below the margin at bottom
18629 of window: scroll_max can no longer be INT_MAX. When aggressive
18630 scrolling is in use, don't let point enter the opposite scroll
18631 margin as result of the scroll.
18632 (syms_of_xdisp) <scroll-conservatively>: Document the
18633 threshold of 100 lines for never-recentering scrolling.

18642 (redisplay_internal): Remove parameter `preserve_echo_area',
18643 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
18645 * indent.c (Fvertical_motion):
18646 * window.c (window_scroll_pixel_based, Frecenter):
18647 Don't pass `need_y_p' to `move_it_by_lines'.

18686 instead of alloca (Bug#8344).
18688 * eval.c (Fbacktrace): Don't assume nargs fits in int.
18689 (Fbacktrace_frame): Don't assume nframes fits in int.
18691 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
18693 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
18696 * term.c (produce_glyphless_glyph): Remove unnecessary test.
18698 * cm.c (calccost): Turn while-do into do-while, for clarity.
18700 * keyboard.c (syms_of_keyboard): Use the same style as later
18701 in this function when indexing through an array. This also
18702 works around GCC bug 48267.
18704 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
18706 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
18708 * chartab.c (sub_char_table_ref_and_range): Redo for slight
18709 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
18711 * keyboard.c, keyboard.h (num_input_events): Now size_t.
18712 This avoids undefined behavior on integer overflow, and is a bit
18713 more convenient anyway since it is compared to a size_t variable.
18715 Variadic C functions now count arguments with size_t, not int.
18716 This avoids an unnecessary limitation on 64-bit machines, which
18717 caused (substring ...) to crash on large vectors (Bug#8344).
18718 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
18719 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
18720 All variadic functions and their callers changed accordingly.
18721 (struct gcpro.nvars): Now size_t, not int. All uses changed.

18723 * editfns.c (general_insert_function): Likewise.
18724 * eval.c (struct backtrace.nargs, interactive_p)
18725 (internal_condition_case_n, run_hook_with_args, apply_lambda)
18726 (funcall_lambda, mark_backtrace): Likewise.
18727 * fns.c (concat): Likewise.
18728 * frame.c (x_set_frame_parameters): Likewise.
18729 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
18730 0 if not found, not -1. All callers changed.
18732 * alloc.c (garbage_collect): Don't assume stack size fits in int.
18733 (stack_copy_size): Now size_t, not int.
18734 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

18739 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
18740 All callers changed.
18742 * lisp.h (multibyte_char_to_unibyte):
18743 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
18744 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

18749 * search.c (Freplace_match):
18750 * xdisp.c (message_dolog, set_message_1): All callers changed.
18752 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
18754 * keyboard.c (safe_run_hook_funcall): New function.
18755 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
18756 don't set the hook to nil, but remove the offending function instead.
18757 (Qcommand_hook_internal): Remove, unused.
18758 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
18759 Vcommand_hook_internal.
18761 * eval.c (enum run_hooks_condition): Remove.
18762 (funcall_nil, funcall_not): New functions.
18763 (run_hook_with_args): Call each function through a `funcall' argument.
18764 Remove `cond' argument, now redundant.
18765 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
18766 (Frun_hook_with_args_until_failure): Adjust accordingly.
18767 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.

18771 * dispextern.h (string_buffer_position): Remove declaration.
18773 * print.c (strout): Remove parameter `multibyte', unused since
18774 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
18776 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
18777 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
18778 All callers changed.
18780 * w32.c (_wsa_errlist): Use braces for struct initializers.
18782 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
18783 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
18784 All callers changed.

18786 used outside xdisp.c).
18787 (cursor_row_p): Remove parameter `w', unused since
18788 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

18790 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
18791 All callers changed.
18793 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
18795 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

18806 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
18808 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>

18821 2011-03-26 Eli Zaretskii <eliz@gnu.org>
18823 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
18824 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
18826 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
18828 * w32.c (read_unc_volume): Use parameter `henum', instead of
18829 global variable `wget_enum_handle'.
18831 * keymap.c (describe_vector): Remove parameters `indices' and
18832 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

18847 * gtkutil.c (xg_maybe_add_timer):
18848 * keyboard.c (readable_events):
18849 * process.c (wait_reading_process_output):
18850 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
18852 * insdel.c (adjust_markers_gap_motion):
18853 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.

18927 2011-03-23 Julien Danjou <julien@danjou.info>
18929 * term.c (Fsuspend_tty, Fresume_tty):
18930 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
18931 * window.c (temp_output_buffer_show):

18938 * callint.c (Fcall_interactively):
18939 * buffer.c (Fkill_all_local_variables):
18940 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
18942 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
18943 unconditionally since it does the check itself.
18945 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
18947 Fix more problems found by GCC 4.5.2's static checks.
18949 * coding.c (encode_coding_raw_text): Avoid unnecessary test
18950 the first time through the loop, since we know p0 < p1 then.
18951 This also avoids a gcc -Wstrict-overflow warning.
18953 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
18954 leading to a memory leak, possible in functions like
18955 load_charset_map_from_file that can allocate an unbounded number
18956 of objects (Bug#8318).
18958 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
18959 that could (at least in theory) be that large.
18961 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
18962 This is less likely to overflow, and avoids undefined behavior if
18963 overflow does occur. All callers changed. Use strtoul to scan
18964 for the unsigned long integer.
18965 (pint2hrstr): Simplify and tune code slightly.
18966 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
18968 * scroll.c (do_scrolling): Work around GCC bug 48228.
18969 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

18976 * fileio.c (Fcopy_file): Report error if fchown or fchmod
18979 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
18981 * process.c (Fmake_network_process): Use socklen_t, not int,
18982 where POSIX says socklen_t is required in portable programs.
18983 This fixes a porting bug on hosts like 64-bit HP-UX, where
18984 socklen_t is wider than int (Bug#8277).
18985 (Fmake_network_process, server_accept_connection):
18986 (wait_reading_process_output, read_process_output):
18989 * process.c: Rename or move locals to avoid shadowing.

18996 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
18997 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
18999 Make tparam.h and terminfo.c consistent.
19000 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
19001 Include tparam.h instead, since it declares them.
19002 * cm.h (PC): Remove extern decl; tparam.h now does this.
19003 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
19004 * terminfo.c: Include tparam.h, to check interfaces.
19005 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
19006 (tparam): Adjust signature to match interface in tparam.h;
19007 this removes some undefined behavior. Check that outstring and len
19008 are zero, which they always are with Emacs.
19009 * tparam.h (PC, BC, UP): New extern decls.
19011 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
19012 (xftfont_open): Rename locals to avoid shadowing.
19014 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
19015 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
19016 (OTF_TAG_SYM): Omit macro if not needed.
19017 (ftfont_list): Remove unused local.
19018 (get_adstyle_property, ftfont_pattern_entity):
19019 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
19020 Rename locals to avoid shadowing.
19022 * xfont.c (xfont_list_family): Mark var as initialized.
19024 * xml.c (make_dom): Now static.
19026 * composite.c (composition_compute_stop_pos): Rename local to
19028 (composition_reseat_it): Remove unused locals.
19029 (find_automatic_composition, composition_adjust_point): Likewise.
19030 (composition_update_it): Mark var as initialized.
19031 (find_automatic_composition): Mark vars as initialized,
19032 with a FIXME (Bug#8290).
19034 character.h: Rename locals to avoid shadowing.
19035 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
19036 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
19037 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
19038 (BUF_DEC_POS): Be more systematic about renaming local temporaries
19039 to avoid shadowing.
19041 * textprop.c (property_change_between_p): Remove; unused.
19043 * intervals.c (interval_start_pos): Now static.
19045 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
19047 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
19048 Rename locals to avoid shadowing.
19050 * sound.c (wav_play, au_play, Fplay_sound_internal):
19051 Fix pointer signedness.
19052 (alsa_choose_format): Remove unused local var.
19053 (wav_play): Initialize a variable to 0, to prevent undefined
19054 behavior (Bug#8278).
19056 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
19058 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
19060 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
19061 clobbering (Bug#8298).
19062 * sysdep.c (sys_subshell): Likewise.
19063 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
19065 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
19066 This should get cleaned up, so that child_setup has the
19067 same signature on all platforms.
19069 * callproc.c (call_process_cleanup): Now static.
19070 (relocate_fd): Rename locals to avoid shadowing.
19072 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
19074 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
19075 not to be necessary, and produces flickering.
19077 2011-03-20 Glenn Morris <rgm@gnu.org>
19079 * config.in: Remove file.
19081 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
19083 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
19084 are now in src/globals.h.
19085 (syms_of_minibuf): Remove spurious & from previous change.

19095 * xfaces.c (Fx_load_color_file):
19096 Read color file from absolute filename (bug#8250).

19102 2011-03-17 Eli Zaretskii <eliz@gnu.org>
19104 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

19111 (sigchld_handler): Now static.
19113 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
19114 That way, the code declares only the vars that it needs.
19115 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
19116 * s/cygwin.h (PTY_ITERATION): Likewise.
19117 * s/darwin.h (PTY_ITERATION): Likewise.

19120 * s/irix6-5.h (PTY_OPEN): Declare stb, to loosen coupling.
19121 * process.c (allocate_pty): Don't declare stb unless it's needed.
19123 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
19124 (CONSTANTLIM): Remove; unused.
19125 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
19126 Define only if needed.
19128 * unexelf.c (unexec): Name an expression,

19200 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
19201 some of which prompt warnings from gcc -Wbad-function-cast.
19202 (Fformat_time_string, Fencode_time, Finsert_char):

19231 (Fmemory_limit): Cast sbrk's returned value to char *.
19233 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

19236 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
19238 Use functions, not macros, for up- and down-casing (Bug#8254).
19239 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
19240 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
19241 to use the following functions instead of these macros.
19242 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
19243 EMACS_INT, since callers assume the returned value fits in int.
19244 (upcase1): Likewise, for UPCASE_TABLE.
19245 (uppercasep, lowercasep, upcase): New static inline functions.
19246 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

19256 (regex_compile, re_match_2_internal): Mark locals as initialized.
19257 (RETALLOC_IF): Define only if needed.
19258 (WORDCHAR_P): Likewise. This one is never needed, but is used
19259 only in a comment talking about a compiler bug, so put inside
19260 the #if 0 of that comment.
19261 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
19262 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

19289 New macros, so that the caller can use some names other than
19290 gcpro1, gcpro2, etc.
19291 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
19293 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
19294 argument, for consistency with GCPRO2_VAR, etc: it is now the
19295 prefix of the variable, not the variable itself. All uses
19297 * dired.c (directory_files_internal, file_name_completion):
19298 Rename locals to avoid shadowing.
19300 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
19301 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
19302 dired.c's scmp function, had undefined behavior.
19303 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
19304 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
19305 * buffer.h: ... to here, because these macros use current_buffer,
19306 and the new implementation with inline functions needs to have
19307 current_buffer in scope now, rather than later when the macros
19309 (downcase, upcase1): New static inline functions.
19310 (DOWNCASE, UPCASE1): Reimplement using these functions.
19311 This avoids undefined behavior in expressions like
19312 DOWNCASE (x) == DOWNCASE (y), which previously suffered
19313 from race conditions in accessing the global variables
19314 case_temp1 and case_temp2.
19315 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
19316 * lisp.h (case_temp1, case_temp2): Remove their decls.
19317 * character.h (ASCII_CHAR_P): Move from here ...
19318 * lisp.h: ... to here, so that the inline functions mentioned
19319 above can use them.
19321 * dired.c (directory_files_internal_unwind): Now static.
19323 * fileio.c (file_name_as_directory, directory_file_name):

19326 (file_name_as_directory): Use const pointers when appropriate.
19327 (Fexpand_file_name): Likewise. In particular, newdir might
19328 point at constant storage, so make it a const pointer.
19329 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
19330 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
19332 (Fset_file_times, Finsert_file_contents, auto_save_error):

19337 to avoid shadowing.
19339 * marker.c (bytepos_to_charpos): Remove; unused.
19341 * lisp.h (verify_bytepos, count_markers): New decls,
19342 so that gcc does not warn that these functions aren't declared.
19344 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
19345 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
19346 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
19347 (copy_text): Remove unused local var.
19349 * filelock.c (within_one_second): Now static.
19350 (lock_file_1): Rename local to avoid shadowing.
19352 * buffer.c (fix_overlays_before): Mark locals as initialized.
19353 (fix_start_end_in_overlays): Likewise. This function should be
19354 simplified by using pointers-to-pointers, but that's a different
19356 (switch_to_buffer_1): Now static.
19357 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
19358 (report_overlay_modification): Rename locals to avoid shadowing.

19361 Fix pointer signedness issue.
19362 (sys_subshell): Mark local as volatile if checking for lint,
19363 to suppress a gcc -Wclobbered warning that does not seem to be right.
19364 (MAXPATHLEN): Define only if needed.
19366 * process.c (serial_open, serial_configure): Move decls from here ...
19367 * systty.h: ... to here, so that they can be checked.
19369 * fns.c (get_random, seed_random): Move extern decls from here ...
19370 * lisp.h: ... to here, so that they can be checked.
19372 * sysdep.c (reset_io): Now static.
19373 (wait_for_termination_signal): Remove; unused.
19375 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

19380 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
19381 (describe_map_tree):
19382 Rename locals to avoid shadowing.
19384 * keyboard.c: Declare functions static if they are not used elsewhere.

19531 For example, without this patch (encode-time 0 0 0 1 1
19532 1152921504606846976) returns the obviously-bogus value (-948597
19533 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
19534 reports time overflow. See
19535 <http://lists.gnu.org/archive/html/emacs-devel/2011-03/msg00470.html>.
19536 * deps.mk (editfns.o): Depend on ../lib/intprops.h.

19551 * editfns.c (time_overflow): New function, refactoring common code.
19552 (Fformat_time_string, Fdecode_time, Fencode_time):
