1 2012-11-05 Eli Zaretskii <eliz@gnu.org>
3 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
5 * w32fns.c Include unistd.h, to avoid compiler warnings on Cygwin.
6 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
7 file descriptor 2 for standard error. (Bug#12805)
9 2012-11-05 Chong Yidong <cyd@gnu.org>
11 * process.c (wait_reading_process_output): Revert previous change.
13 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
15 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
16 This removes code that has been obsolete since around 1990.
17 * callproc.c (Fcall_process):
19 * process.c (create_process):
20 * term.c (dissociate_if_controlling_tty):
22 * callproc.c (child_setup): Assume setpgid exists and behaves as
23 per POSIX.1-1988 or later.
24 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
25 * emacs.c (shut_down_emacs):
26 * sysdep.c (sys_suspend, init_foreground_group):
27 Assume getpgrp behaves as per POSIX.1-1998 or later.
28 * msdos.c (setpgrp): Remove.
29 (tcgetpgrp, setpgid, setsid): New functions.
30 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
31 * term.c (no_controlling_tty): Remove; unused.
32 * w32proc.c (setpgrp): Remove.
33 (setsid, tcgetpgrp): New functions.
35 Simplify by assuming __fpending.
36 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
37 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
38 Do not assume that __fpending's result fits in int.
40 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
42 Remove EMACS_OUTQSIZE+sleep hack.
43 * dispnew.c (update_frame_1): Remove hack for terminals slower
44 than 2400 bps, which throttled Emacs by having it sleep. This
45 code hasn't worked since at least 2007, when the multi-tty stuff
46 was added, and anyway those old terminals are long dead.
47 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
48 without the dispnew.c change, as dispnew.c doesn't include systty.h.
50 Fix data-loss with --version (Bug#9574).
51 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
52 as we can't assume that emacs_strerror is initialized, and strerror
54 (main): Invoke atexit earlier, to catch earlier instances of
55 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
57 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
59 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
60 (keyDown): Remap keypad keys to X11 virtual key codes.
62 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
64 Fix data-loss with --batch (Bug#9574).
65 * emacs.c: Include <close-stream.h>.
66 (close_output_streams): New function.
67 (main): Pass it to atexit, so that Emacs closes stdout and stderr
68 and handles errors appropriately.
69 (Fkill_emacs): Don't worry about flushing, as close_output_stream
72 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
73 The symptom is a diagnostic "GLib-WARNING **: In call to
74 g_spawn_sync(), exit status of a child process was requested but
75 SIGCHLD action was set to SIG_IGN and ECHILD was received by
76 waitpid(), so exit status can't be returned." The diagnostic
77 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
78 The real bug is a race condition between Emacs and glib: Emacs
79 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
80 so that glib can't find it. Work around the bug by invoking
81 waitpid only on subprocesses that Emacs itself creates.
82 * process.c (create_process, record_child_status_change):
83 Don't use special value -1 in pid field, as the caller now must
84 know the pid rather than having the callee infer it. The
85 inference was sometimes incorrect anyway, due to another race.
86 (create_process): Set new 'alive' member if child is created.
87 (process_status_retrieved): New function.
88 (record_child_status_change): Use it.
89 Accept negative 1st argument, which means to wait for the
90 processes that Emacs already knows about. Move special-case code
91 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
92 processes that have already been waited for, by testing and
93 clearing new 'alive' member.
94 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
95 now does this internally.
96 (handle_child_signal): Let record_child_status_change do all
97 the work, since we do not want to reap all exited child processes,
98 only the child processes that Emacs itself created.
99 * process.h (Lisp_Process): New boolean member 'alive'.
101 Omit duplicate definitions no longer needed with gcc -g3.
102 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
103 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
104 Define only as macros. There's no longer any need to also define
105 these symbols as enums or as constants, since we now assume
106 gcc -g3 when debugging.
108 2012-11-03 Eli Zaretskii <eliz@gnu.org>
110 * lisp.mk: Adjust comments to the fact that term/internal is now
111 loaded from loadup.el.
113 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
114 (msdos_fatal_signal): New function.
115 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
118 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
119 for GCC versions before 4.
120 (emacs_raise): Define to call msdos_fatal_signal.
122 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
123 iterator when starting in the middle of a display or overlay
126 2012-11-03 Chong Yidong <cyd@gnu.org>
128 * process.c (wait_reading_process_output): Clean up the last
131 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
133 * process.c (wait_reading_process_output): Avoid a race condition
134 with SIGIO delivery (Bug#11536).
136 2012-11-03 Chong Yidong <cyd@gnu.org>
138 * buffer.c (cursor_type): Untabify docstring.
140 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
142 * frame.h (struct frame): Drop can_have_scroll_bars member
143 which is meaningless for a long time. Adjust comments.
144 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
145 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
147 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
149 * window.c (decode_next_window_args): Update window arg after
150 calling decode_live_window and so fix crash reported at
151 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
152 by Juanma Barranquero <lekktu@gmail.com>.
153 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
154 * font.c (Ffont_at): Likewise.
156 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
158 * widget.c (resize_cb): New function.
159 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
160 (EmacsFrameResize): Check if all is up to date before changing frame
163 2012-11-02 Eli Zaretskii <eliz@gnu.org>
165 Implement backtrace output for fatal errors on MS-Windows.
166 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
167 (BACKTRACE_LIMIT_MAX): New macro.
168 (w32_backtrace): New function.
169 (emacs_abort): Use w32_backtrace when the user chooses not to
170 attach a debugger. Update the text of the abort dialog.
172 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
174 Window-related stuff cleanup here and there.
175 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
176 Use decode_any_window.
177 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
178 * xdisp.c (Fformat_mode_line): Likewise.
179 * font.c (Ffont_at): Use decode_live_window.
180 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
181 * window.c (decode_next_window_args): Likewise.
182 (decode_any_window): Remove static.
183 * window.h (decode_any_window): Add prototype.
184 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
185 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
188 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
190 Remove pad from struct input_event.
191 * termhooks.h (struct input_event): Remove padding field.
193 * keyboard.c (event_to_kboard): Simplify because frame_or_window
194 member is never cons for a long time. Adjust comment.
195 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
196 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
197 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
198 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
200 2012-11-01 Eli Zaretskii <eliz@gnu.org>
202 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
204 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
206 Fix crash when using Emacs as commit editor for git (Bug#12697).
207 * callproc.c (setpgrp): Remove macro, as we now use setpgid
208 and it is configured in conf_post.h.
209 (Fcall_process): Don't invoke both setsid and setpgid; the former
210 is enough, if it exists.
211 * callproc.c (Fcall_process, child_setup):
212 * process.c (create_process): Use setpgid.
213 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
215 * dispnew.c (init_display): Initialize the foreground group
216 if we are running a tty display.
217 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
218 * lisp.h (init_foreground_group): New decl.
219 * sysdep.c (inherited_pgroup): New static var.
220 (init_foreground_group, tcsetpgrp_without_stopping)
221 (narrow_foreground_group, widen_foreground_group): New functions.
222 (init_sys_modes): Narrow foreground group.
223 (reset_sys_modes): Widen foreground group.
225 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
227 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
229 2012-10-31 Martin Rudalics <rudalics@gmx.at>
231 * minibuf.c (read_minibuf): Restore current buffer since
232 choose_minibuf_frame calling Fset_frame_selected_window may
233 change it (Bug#12766).
235 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
237 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
239 2012-10-30 Kenichi Handa <handa@gnu.org>
241 * font.c (Ffont_at): If WINDOW is specified and it is not
242 displaying the current buffer, signal an error.
244 2012-10-29 Daniel Colascione <dancol@dancol.org>
246 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode): In
247 preparation for fixing bug#12739, move these functions from
250 * coding.h, coding.c: ... to here, and compile them only when
251 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
252 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
254 2012-10-28 Eli Zaretskii <eliz@gnu.org>
256 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
257 (timer_loop, getitimer, setitimer): Use it instead of
258 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
260 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
263 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
265 * nsterm.m (NO_APPDEFINED_DATA): New define.
266 (last_appdefined_event_data): New variable
267 (last_appdefined_event): Remove.
268 (ns_select): Initialize t from last_appdefined_event_data instead
269 of [last_appdefined_event data1].
270 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
271 remove last_appdefined_event (Bug#12698).
273 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
275 * frame.c (x_set_font): Catch internal error.
277 2012-10-27 Eli Zaretskii <eliz@gnu.org>
279 Avoid overflow in w32 implementation of interval timers.
280 When possible, for ITIMER_PROF count only times the main thread
282 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
283 'volatile ULONGLONG' types. All the other data which was
284 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
285 (GetThreadTimes_Proc): New typedef.
286 (w32_get_timer_time): New function, returns a suitable time value
288 (timer_loop): Enter critical section when accessing ULONGLONG
289 values of the itimer_data struct, as these accesses are no longer
290 atomic. Call 'w32_get_timer_time' instead of 'clock'.
291 Remove unused variable.
292 (init_timers): Initialize s_pfn_Get_Thread_Times.
293 (start_timer_thread): Don't assign itimer->caller_thread here.
294 (getitimer): Assign itimer->caller_thread here.
295 (setitimer): Always call getitimer to get the value of ticks_now.
296 (sys_spawnve): Avoid compiler warning about format mismatch.
298 2012-10-26 Eli Zaretskii <eliz@gnu.org>
300 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
301 mouse movement events if the menu bar is active. This avoids
302 producing a busy "hour-glass" cursor by Windows if the mouse
303 pointer is positioned over a tooltip shown for some menu item.
305 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
307 Don't assume process IDs fit in int.
308 * emacs.c (shut_down_emacs) [!DOS_NT]:
309 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
310 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
311 Use pid_t, not int, to store process IDs, as 'int'
312 is not wide enough on a few platforms (e.g., AIX and IRIX).
314 2012-10-23 Kenichi Handa <handa@gnu.org>
316 The following change is to make face-font-rescale-alist work
317 correctly for non-ASCII fonts.
319 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
320 (font_open_for_lface): Handle Vface_font_rescale_alist.
322 2012-10-23 Chong Yidong <cyd@gnu.org>
324 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
326 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
328 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
330 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
332 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
335 2012-10-21 Glenn Morris <rgm@gnu.org>
337 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
339 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
342 * frame.c (Fmouse_position, Fmouse_pixel_position):
343 * xdisp.c (produce_stretch_glyph):
344 Declare local vars only when they're needed.
345 This is clearer and avoids a warning on OpenBSD about unused vars.
346 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
347 This is safer, and avoids OpenBSD warnings about unused vars.
348 * keyboard.c (record_menu_key): Remove unnecessary decl.
349 (poll_timer): Define only if POLL_FOR_INPUT is defined.
350 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
351 as our definition clashes with OpenBSD's.
352 * xfaces.c (load_face_colors, check_lface_attrs)
353 (get_lface_attributes_no_remap, get_lface_attributes)
354 (lface_fully_specified_p, x_supports_face_attributes_p)
355 (tty_supports_face_attributes_p, face_fontset, realize_face)
356 (realize_x_face, realize_tty_face):
357 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
358 merely Lisp_Object *. This is more informative and avoids
359 a warning on OpenBSD about accessing beyond an object's size.
361 2012-10-20 Chong Yidong <cyd@gnu.org>
363 * lread.c (Fload): Doc fix (Bug#12592).
365 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
367 * font.c (Ffont_at): Fix previous change.
369 2012-10-19 Eli Zaretskii <eliz@gnu.org>
371 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
372 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
375 * alloc.c (NSTATICS): Decrease to 0x800.
377 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>
379 * fns.c (Fnreverse): Include the problem element when signalling an
382 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
384 * nsterm.m (ns_select): Check writefds before call to
385 FD_ISSET (Bug#12668).
387 2012-10-18 Daniel Colascione <dancol@dancol.org>
389 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
390 (staticpro): If we run out of staticpro slots, die with an
391 informative error instead of just calling emacs_abort.
393 2012-10-18 Martin Rudalics <rudalics@gmx.at>
395 Fix two flaws reported by Dmitry Antipov.
396 * window.c (Ftemp_output_buffer_show): Remove.

405 ($(BLD)/unexw32.$(O)):
406 ($(BLD)/fileio.$(O)):
407 ($(BLD)/dispnew.$(O)): Update dependencies.
409 * w32term.h (w32_initialize_display_info, initialize_w32_display):
412 * w32proc.c: Include ctype.h.
414 * w32.h (init_environment, check_windows_init_file)
415 (syms_of_ntproc, syms_of_ntterm, dostounix_filename)
416 (unixtodos_filename, init_winsock, srandom, random, sys_pipe)
417 (set_process_dir, sys_spawnve, register_child, sys_sleep, getwd)
418 (sys_link): Add prototypes.
420 * w32.c: Include w32select.h.
421 (sys_access, e_malloc, sys_select): Add prototypes.
422 (emacs_gnutls_pull): 'timeout' is now EMACS_TIME, not struct timeval.
424 * vm-limit.c [WINDOWSNT]: Include w32heap.h.
426 * unexw32.c: Include lisp.h and w32.h.
428 * term.c [WINDOWSNT]: Include w32term.h.
430 * process.c [WINDOWSNT]: Add prototype of sys_select.
432 * fileio.c [WINDOWSNT]: Include w32.h.
434 * dispnew.c [WINDOWSNT]: Include w32.h.
436 * cygw32.c (Fcygwin_convert_path_to_windows)
437 (Fcygwin_convert_path_from_windows): Use EQ to compare 2
438 Lisp_Object values. (Bug#12661)
440 * w32fns.c (w32_msg_pump): Use XIL instead of casting an integer
441 to Lisp_Object. (Bug#12661)
443 2012-10-17 Kenichi Handa <handa@gnu.org>
445 * xdisp.c (reseat_1): Make the information stored in it->cmp_it
448 2012-10-17 Dmitry Antipov <dmantipov@yandex.ru>

451 reset its buffer pointer to NULL (Bug#12652).
453 2012-10-17 Dmitry Antipov <dmantipov@yandex.ru>
455 Do not verify indirection counters of killed buffers (Bug#12579).

477 2012-10-15 Martin Rudalics <rudalics@gmx.at>
479 * window.c (Fwindow_end): Rewrite check whether cached position
480 can be used (Bug#12600).
481 (resize_frame_windows, grow_mini_window, shrink_mini_window):
482 Set windows_or_buffers_changed.
484 2012-10-15 Daniel Colascione <dancol@dancol.org>
486 * dbusbind.c: Fix cygw32 build break when compiling with dbus
487 enabled by undefining the symbol "interface", which the platform
488 headers define to something incompatible.
490 2012-10-14 Daniel Colascione <dancol@dancol.org>
492 * image.c (init_tiff_functions, init_imagemagick_functions)
493 (init_svg_functions): Fix cygw32 build break by using these
494 functions only when WINDOWSNT _and_ HAVE_NTGUI.
496 2012-10-14 Jan Djärv <jan.h.d@swipnet.se>
498 * nsterm.m (ns_select): Count fd:s in writefs also (Bug#12422).

515 Fix some stat-related races.
516 * fileio.c (Fwrite_region): Avoid race condition if a file is
517 removed or renamed by some other process immediately after Emacs
518 writes it but before Emacs stats it. Do not assume that stat (or
520 * image.c (slurp_file): Resolve the file name with fopen + fstat
521 rather than stat + fopen.
522 (pbm_read_file) [0]: Remove unused code with stat race.

549 * fileio.c (check_existing): New function.
550 (make_temp_name, Ffile_exists_p, Ffile_writable_p): Call it
551 instead of calling 'stat', when what's needed is to check whether
552 a file exists. This avoids expensive system calls on MS-Windows.
555 * w32.c (init_environment): Call 'check_existing' instead of 'stat'.
557 * lread.c (openp) [WINDOWSNT]: Call 'access' instead of 'stat' to
558 determine whether a file exists and is not a directory.

645 Use bool for boolean.
646 * keyboard.c (timers_run, swallow_events)
647 (detect_input_pending_run_timers):
648 * process.c (wait_reading_process_output):
649 Use unsigned for counter where wraparound-on-overflow is desired,
650 since unsigned is guaranteed to have that behavior and signed is not.
651 (read_char): Use ptrdiff_t for string length.
652 (get_input_pending): Remove first argument, since it was always
653 the same pointer-to-int (now pointer-to-boolean) &input_pending,
654 and behave as if it had that value. Return new value of
655 input_pending. All callers changed.
656 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
657 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's

677 Clean out old termopts cruft.
678 * termopts.h (flow_control, meta_key): Remove unused decls.
679 * dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c:
680 Don't include termopts.h.
682 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
684 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
686 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
688 * commands.h (immediate_quit): Remove duplicate decl.
690 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>

695 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
697 2012-10-09 Eli Zaretskii <eliz@gnu.org>
699 * w32fns.c (w32_last_error): Change the return value to DWORD, to
700 match what GetLastError returns. Explain why the function is
703 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
704 'is_tooltip_frame', to avoid confusion with its global namesake.
706 2012-10-08 Daniel Colascione <dancol@dancol.org>
708 * xdisp.c (start_hourglass): Call w32_note_current_window when
709 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
710 build that caused Emacs to display the hourglass cursor forever.
712 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
713 which is broken under remote desktop, calculate the number of
714 colors available for a display based on the display's number of
715 planes and number of bits per pixel per plane. (bug#10397).
717 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
719 * nsfont.m (Vfonts_in_cache): New variable.
720 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
721 are used. Add cached fonts to Vfonts_in_cache.
722 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
724 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
726 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
728 (FONT_H): Define after FRAME_H.
729 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
732 * w32term.c: Remove leftover declaration of keyboard_codepage.
734 2012-10-08 Eli Zaretskii <eliz@gnu.org>
736 * makefile.w32-in (FONT_H): Add $(FRAME_H).
737 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
738 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
739 (GLOBAL_SOURCES): Add cygw32.c.
740 ($(BLD)/unexw32.$(O)):
742 ($(BLD)/w32console.$(O)):
743 ($(BLD)/w32fns.$(O)):
744 ($(BLD)/w32heap.$(O)):

748 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
750 (x_to_w32_color): Don't modify the argument, modify a copy instead.
752 2012-10-08 Daniel Colascione <dancol@dancol.org>
754 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
755 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
756 accidental message numbering hole. Change other messages to
759 * w32select.h (HAVE_W32SELECT): Remove.
761 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
762 w32common.h instead of w32heap.h.
764 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)

772 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
773 (w32_minor_version, w32_build_number, w32_subtype):
774 Remove duplicate definitions.
776 * w32fns.c: Include w32common.h; include w32heap.h only in
779 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
780 Use `report_file_error' instead of `error' in order to better
781 inform users of what went wrong. Increase NTGUI_UNICODE file
782 dialog box file name length to 32k, the maximum allowed by the NT
785 * w32common.h: New file.
786 (ROUND_UP, ROUND_DOWN, get_page_size)
787 (get_allocation_unit, get_processor_type, get_w32_major_version)
788 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
789 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
790 (OS_NT, os_subtype, cache_system_info): Move here.
792 * unexw32.c, unexcw.c: Include w32common.h.
794 * emacs.c (main): Use (defined (WINDOWSNT) || defined
795 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
796 to call syms_of_w32select.
798 * cygw32.h: Remove obsolete EXFUN declarations.
800 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
802 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
803 of w32inevt.o from SOME_MACHINE_OBJECTS.
805 2012-10-08 Daniel Colascione <dancol@dancol.org>
807 * image.c: Permanent fix for JPEG compilation issue --- limit
808 jpeglib `boolean' redefinition to Cygwin builds.
810 2012-10-08 Eli Zaretskii <eliz@gnu.org>
812 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
814 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
817 2012-10-08 Daniel Colascione <dancol@dancol.org>
819 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
820 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
821 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
822 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
823 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
824 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
825 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
826 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
827 now a supported configuration.
829 * Makefile.in: consolidate image variables into LIBIMAGE; add
830 W32_OBJ and W32_LIBS. Compile new files.
833 (_DebPrint) declare tracing facility for W32 debugging. We need
834 to unify tracing later.
836 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
837 unconditional use of W32 Unicode functions. Cygwin runs only on
838 100% Unicode operating systems.
840 * cygw32.c: New file. Define Cygwin-specific facilities.
841 (Fcygwin_convert_path_to_windows)
842 (Fcygwin_convert_path_from_windows): New user functions for
843 accessing Cygwin path-munging routines.
845 * cygw32.h: New file.
846 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
847 UTF-16LE strings temporarily inside non-Lisp-visible string
850 (w32_strerror): Just what it says on the tin.
852 * emacs.c: Make the NS fork-then-exec code for daemon-launching
853 also run for Cygwin; both systems have the same problem with using
854 GUI facilities in a forked child. Also call syms_of_cygw32,
855 syms_of_w32select in correct places.
857 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
858 needs fork-then-exec for daemon launching.
860 * font.h: Include frame.h.
862 * image.c: Use the image library cache machinery only when we're
863 compiling for native WINDOWSNT; Cygwin can use shared libraries
864 like any other Unixlike system.
866 * keyboard.c: Clarify a comment regarding the input loop.
868 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
869 functions directly instead of trying to detect at runtime that our
870 host operating system supports them. We make this change for two
871 reasons: Cygwin lacks support for the multibyte character
872 conversion functions used by the legacy menu code, and Cygwin
873 never needs to rely on non-Unicode APIs.
875 * unexw32.c (hinst): Declare extern.
877 * w32.c: Change header order;
878 (w32_strerror): Move to w32fns.c because we need it for
879 non-WINDOWSNT builds.
881 * w32.h: Add #error macro to make sure we don't include w32.h for
882 Cygwin builds. Remove w32select declarations.
884 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
885 w32fns.c. w32console.c is WINDOWSNT-only.
887 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
888 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
890 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
891 (w32_major_version, w32_minor_version, w32_build_number)
892 (os_subtype, sound_type): Define here
893 (w32_defined_color): Make color parameter const for consistency
894 with other _defined_color functions.
895 (w32_createwindow): Unconditionally call w32_init_class instead of
896 doing so only when hprevinst is non-NULL. Plumbing hprevinst
897 through the code is complex and unnecessary because class
898 registration is practically free.
899 (w32_name_of_message): New EMACSDEBUG-only function.
900 (Fset_message_beep): Move here
901 (Fx_open_connection): Require that the display name for Windows be
902 "w32" for consistency, emacsclient disambiguation, and maybe, one
903 day, multi-window-system support.
904 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
905 Cygwin files for W32 GUI facilities, since these clearly don't
908 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
909 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
910 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
911 (w32_last_error): Remove.
913 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
915 * w32heap.c (syspage_mask): Declare here.
916 (cache_system_info): Remove.
918 * w32inevt.c (faked_key): Define globally, not statically.
919 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
920 (w32_console_toggle_lock_key): Move to w32fns.c.
922 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
924 * w32proc.c (_DebPrint): Move to w32fns.c.
925 * w32select.c: Include string.h, stdio.h for Cygwin.
926 * w32select.h: New File.
928 * w32term.c: Include io.h for non-CYGWIN builds; needed for
930 (w32_message_fd): New variable. Under Cygwin, holds the file
931 descriptor the system used to tell us about pending thread
934 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
935 that prevented compilation under non-WINDOWSNT systems.
937 (w32_initialize): Open /dev/windows and assign it to
938 w32_message_fd. Provide w32 feature.
940 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
941 (WM_EMACS_INPUT_READY): add.
942 (prepend_msg, w32_message_fd): Declare globally.
945 (keyboard_handle): Use only when WINDOWSNT.
946 (notify_msg_ready): New function. Posts a message to the main
947 thread's message queue under CYGWIN, which wakes up the main
948 thread from select(2) by making the /dev/windows file descriptor
949 ready. Under WINDOWSNT, it sets an event the same way the old
952 (post, prepend_msg): Actually call notify_msg_ready instead of
953 setting the input event directly.
955 2012-10-07 Eli Zaretskii <eliz@gnu.org>
957 * ralloc.c (relinquish): If a heap is ready to be relinquished,
958 but it still has blocs in it, don't return it to the system,
959 instead of aborting. (Bug#12402)
961 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
963 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
965 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
966 MAC_OS_X_VERSION_10_6.
967 (syms_of_nsterm): Remove comment about Panther and above for

974 MAC_OS_X_VERSION_10_4.
976 * nsmenu.m (fillWithWidgetValue:): Remove code for <
977 MAC_OS_X_VERSION_10_2.
979 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
981 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
982 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
984 * nsterm.m (ns_in_resize): Remove (Bug#12479).
985 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
986 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
987 Remove ns_in_resize check.
988 (ns_clear_frame_area): Remove resize handle code.
990 * nsfns.m (ns_in_resize): Remove.
991 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
992 Remove ns_in_resize check.
994 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
996 Improve sys_siglist detection.
997 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
998 defined as a macro, as is done in Solaris.
999 (sys_siglist_entries): New macro.
1000 (save_strsignal): Use it.
1001 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
1002 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
1004 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
1006 * nsfns.m (Fx_create_frame): Call x_default_parameter with
1007 fullscreen/Fullscreen.
1009 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
1010 tobar_height is new.
1012 * nsterm.m (x_make_frame_visible): Check for fullscreen.
1013 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
1014 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
1015 (windowDidResize:): Check for correct window if old style fullscreen.
1016 Capitalize word in comment. Remove incorrect comment.
1017 (initFrameFromEmacs:): tbar_height renamed tibar_height.
1018 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
1019 error in drawing background.
1020 (toggleFullScreen:): Remove comment. Rearrange calls.
1021 Set toolbar values to zero, save old height in tobar_height.

1023 (canBecomeMainWindow): New function.
1025 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
1027 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
1029 2012-10-05 Eli Zaretskii <eliz@gnu.org>
1031 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
1033 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
1034 that time stamps of directories could also be changed.
1035 Don't request the too broad GENERIC_WRITE, only the more restrictive
1036 FILE_WRITE_ATTRIBUTES access rights.
1038 * fileio.c (Fset_file_times): Special-case ignoring errors for
1039 directories only on MSDOS, not on MS-Windows.
1041 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
1043 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
1045 2012-10-04 Eli Zaretskii <eliz@gnu.org>

1048 see whether CreateFile failed.
1050 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
1052 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
1053 to avoid similar races.
1054 * keyboard.c (pending_signals): Now bool, not int.
1056 Port timers to OpenBSD, plus check for timer failures.
1057 OpenBSD problem reported by Han Boetes.
1058 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
1060 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
1061 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
1062 like OpenBSD, which has timer_settime but does not declare it.
1063 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
1064 whether to use itimerspec-related primitives. All uses of
1065 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
1067 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
1069 * profiler.c (handle_profiler_signal): Fix a malloc race
1070 that caused Emacs to hang on Fedora 17 when profiling Lisp.
1072 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
1074 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
1076 2012-10-02 Eli Zaretskii <eliz@gnu.org>
1078 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
1079 consistent with the change in return value of 'safe_strsignal'.
1081 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
1083 Prefer plain 'static' to 'static inline' (Bug#12541).
1084 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
1085 (bidi_set_sor_type, bidi_push_embedding_level)
1086 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

1091 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
1092 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
1093 Now 'static', not 'static inline'.
1095 Count overruns when profiling; change units to ns.
1096 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
1097 Give extra weight to samples after overruns, to attempt to count
1098 the time more accurately.
1099 (setup_cpu_timer): Change sampling interval units from ms to ns, since
1100 the underlying primitives nominally do ns.
1101 (Fprofiler_cpu_start): Document the change. Mention that
1102 the sampling intervals are only approximate.
1104 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
1106 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
1108 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
1109 case for the special 0 coding-system.
1111 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
1112 (Fmake_overlay): Remove redundant tests.
1113 (fix_start_end_in_overlays): Remove redundant recentering.
1115 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
1117 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
1118 Update dependencies.
1120 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
1122 Fix a malloc race condition involving strsignal.
1123 A signal can arrive in the middle of a malloc, and Emacs's signal
1124 handler can invoke strsignal, which can invoke malloc, which is
1125 not portable. This race condition bug makes Emacs hang on GNU/Linux.
1126 Fix it by altering the signal handler so that it does not invoke
1128 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
1129 * process.c (status_message): Use const pointer, in case strsignal
1130 is #defined to safe_strsignal.
1131 * sysdep.c (sys_siglist, init_signals): Always define and
1132 initialize a substitute sys_siglist if the system does not define
1133 one, even if HAVE_STRSIGNAL.
1134 (safe_strsignal): Rename from strsignal. Always define,
1135 using sys_siglist. Return a const pointer.
1136 * syssignal.h (safe_strsignal): New decl.
1137 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
1139 2012-10-01 Eli Zaretskii <eliz@gnu.org>
1141 * w32proc.c (timer_loop): Fix code that waits for timer
1142 expiration, to avoid high CPU usage.
1144 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
1146 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
1147 (sweep_weak_table): Remove redundant prototypes.
1149 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
1151 * emacs.c: Move the inclusion of TERM_HEADER after including
1152 windows.h on WINDOWSNT. This avoids compilation problems with
1155 2012-10-01 Eli Zaretskii <eliz@gnu.org>
1157 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
1158 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
1159 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
1160 as the previous version used 'void *'.
1162 * ralloc.c (ROUNDUP): Fix last change.
1163 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
1166 * w32proc.c <disable_itimers>: New static flag.
1167 (init_timers): Initialize it to zero, after creating the critical
1168 sections used by the timer threads.
1169 (term_timers): Set to 1 before deleting the critical sections.
1170 (getitimer, setitimer): If disable_itimers is non-zero, return an
1171 error indication without doing anything. Reported by Fabrice
1172 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
1173 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
1175 [!HAVE_SETITIMER]: Behave as the previous version that didn't
1178 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
1179 term_ntproc after all the other bookkeeping, to get timers working
1180 as long as possible.
1182 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
1184 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
1185 Suggested by Juri Linkov in
1186 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
1188 Prefer plain 'static' to 'static inline' (Bug#12541).
1189 With static functions, modern compilers inline pretty well by
1190 themselves; advice from programmers often hurts as much as it helps.
1191 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
1192 this change shrinks the text size of the Emacs executable by 1.1%
1193 without affecting CPU significantly in my benchmark.
1194 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

1274 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
1276 Revert the FOLLOW-SYMLINKS change for file-attributes.
1277 Doing it right would require several changes to Tramp, and there's
1278 not enough time to get that tested before the freeze today.
1279 * dired.c (directory_files_internal, Ffile_attributes):
1282 * frame.c (x_report_frame_params): Port better to wider ints.
1283 Do not assume that EMACS_UINT is the same width as uprintmax_t,
1284 or that pointers can be printed in 15 decimal digits.
1285 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

1322 (check_memory_limits): Adjust prototypes of real_morecore and
1323 __morecore to receive argument of type ptrdiff_t. Use size_t for

1403 * xdisp.c (start_hourglass, cancel_hourglass): Now used on
1405 (start_hourglass) [WINDOWSNT]: Call w32_note_current_window.
1407 * w32.h (init_timers, term_timers): Add prototypes.
1409 2012-09-30 Kenichi Handa <handa@gnu.org>
1411 * coding.c (decode_coding_ccl, encode_coding_ccl): Pay attention
1412 to the buffer relocation which may be caused by ccl_driver.

1437 (windowWillResize:toSize:): Check if frame is still maximized.
1438 (initFrameFromEmacs:): Initialize fs_state, fs_before_fs,
1439 next_maximized, maximized_width, maximized_height and nonfs_window.
1440 Call setCollectionBehavior if NEW_STYLE_FS. Initialize bwidth and
1442 (windowWillUseStandardFrame:defaultFrame:): Update frame parameter
1443 fullscreen. Set maximized_width/height. Act on next_maximized.
1445 * nsterm.h (MAC_OS_X_VERSION_10_7, MAC_OS_X_VERSION_10_8): New.
1446 (EmacsView): Add variables for fullscreen.
1447 (handleFS, setFSValue, toggleFullScreen): New in EmacsView.
1448 (EmacsFSWindow): New interface for fullscreen.
1450 2012-09-30 Juanma Barranquero <lekktu@gmail.com>
1452 * makefile.w32-in ($(BLD)/profiler.$(O)): Update dependencies.
1454 2012-09-30 Chong Yidong <cyd@gnu.org>
1456 * fns.c (Frandom): Doc fix.
1458 2012-09-30 Martin Rudalics <rudalics@gmx.at>
1460 * window.c (Vwindow_combination_limit): New default value.
1461 (Qwindow_size): New symbol replacing Qtemp_buffer_resize.
1463 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
1465 * syssignal.h (PROFILER_CPU_SUPPORT): Don't define if PROFILING.
1466 Suggested by Eli Zaretskii in
1467 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
1469 2012-09-30 Eli Zaretskii <eliz@gnu.org>
1471 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
1472 HAVE_TIMER_SETTIME is defined.
1474 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
1476 Profiler improvements: more-accurate timers, overflow checks.
1477 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
1478 signal.h, setjmp.h. Include systime.h instead.
1479 (saturated_add): New function.
1480 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.
1481 (record_backtrace, handle_profiler_signal): Saturate on fixnum overflow.
1482 (profiler_timer, profiler_timer_ok) [HAVE_TIMER_SETTIME]:
1484 (enum profiler_cpu_running): New enum.
1485 (profiler_cpu_running): Now of that enum type, not bool.
1486 All uses changed to store the new value.
1487 (handle_profiler_signal): Rename from sigprof_handler_1,
1488 for consistency with other handlers. Do not check whether
1489 cpu_log is a hash-table if garbage collecting, since it
1490 doesn't matter in that case.
1491 (deliver_profiler_signal): Rename from sigprof_handler,
1492 for consistency with other handlers.
1493 (setup_cpu_timer): New function, with much of what used to be in
1494 Fprofiler_cpu_start. Check for out-of-range argument.
1495 Prefer timer_settime if available, and prefer
1496 thread cputime clocks, then process cputime clocks, then
1497 monotonic clocks, to the old realtime clock. Use make_timeval
1498 to round more-correctly when falling back to setitimer.
1499 (Fprofiler_cpu_start): Use it.
1500 (Fprofiler_cpu_stop): Prefer timer_settime if available.
1501 Don't assume that passing NULL as the 2nd argument of setitimer
1502 is the same as passing a pointer to all-zero storage.
1503 Ignore SIGPROF afterwards.
1504 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
1505 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
1506 non-fatal signal handlers. Ignore SIGPROF on startup.
1507 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
1508 in profiler.c, since sysdep.c now uses it.
1510 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
1511 Suggested by Eli Zaretskii in
1512 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

1525 (Fbacktrace_frame): Adjust accordingly.
1527 2012-09-28 Glenn Morris <rgm@gnu.org>
1529 * eval.c (Frun_hook_with_args, Frun_hook_with_args_until_success)
1530 (Frun_hook_with_args_until_failure): Doc fixes.
1532 2012-09-28 Eli Zaretskii <eliz@gnu.org>
1534 * xdisp.c (syms_of_xdisp) <Qredisplay_internal>: Rename from
1535 Qautomatic_redisplay and change the symbol name. All users changed.
1537 2012-09-28 Tomohiro Matsuyama <tomo@cx4a.org>
1539 * profiler.c (sigprof_handler): Fix race condition.

1548 * Makefile.in (LIB_TIMER_TIME): New macro.
1550 * atimer.c (alarm_timer, alarm_timer_ok, set_alarm, init_atimer):
1551 Use HAVE_TIMER_SETTIME, not SIGEV_SIGNAL, to decide whether to

1556 * profiler.c (Fprofiler_cpu_start): Remove unnecessary flag SA_SIGINFO.
1558 2012-09-26 Juanma Barranquero <lekktu@gmail.com>
1560 * makefile.w32-in ($(BLD)/profiler.$(O)): Update dependencies.
1562 2012-09-26 Paul Eggert <eggert@cs.ucla.edu>
1564 * character.h (MAYBE_UNIFY_CHAR): Remove.
1565 * charset.c, charset.h (maybe_unify_char): Now static.
1566 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
1567 Since this stuff is now private to charset.c, there's no need for
1568 a public macro and no need to inline by hand.
1570 2012-09-26 Tomohiro Matsuyama <tomo@cx4a.org>
1571 Stefan Monnier <monnier@iro.umontreal.ca>
1572 Juanma Barranquero <lekktu@gmail.com>

1597 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
1599 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
1601 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
1603 Prefer POSIX timers if available.
1604 They avoid a race if the timer is too close to the current time.
1605 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
1606 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
1607 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
1609 2012-09-25 Eli Zaretskii <eliz@gnu.org>
1611 * coding.c (CHAR_STRING_ADVANCE_NO_UNIFY): Make it an alias of
1612 CHAR_STRING_ADVANCE.
1613 (STRING_CHAR_ADVANCE_NO_UNIFY): Make it an alias of
1614 STRING_CHAR_ADVANCE.
1616 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
1618 Move Vlibrary_cache to emacs.c and reset before dumping.

1630 (globals_of_w32) <Vlibrary_cache>: Do not initialize.
1632 * w32.h (Vlibrary_cache): Do not declare.
1634 2012-09-25 Eli Zaretskii <eliz@gnu.org>
1636 * w32proc.c (sys_signal): Handle all signals defined by the
1637 MS-Windows runtime, not just SIGCHLD. Actually install the signal
1638 handlers for signals supported by Windows. Don't override
1639 term_ntproc as the handler for SIGABRT.
1640 (sigaction): Rewrite to call sys_signal instead of duplicating its
1642 (sys_kill): Improve commentary.
1644 * w32.c (term_ntproc): Accept (and ignore) one argument, for
1645 consistency with a signature of a signal handler. All callers
1647 (init_ntproc): Accept an argument DUMPING. If dumping, don't
1648 install term_ntproc as a signal handler for SIGABRT, as that
1649 should be done by the dumped Emacs.
1651 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
1653 * w32select.c (term_w32select): Protect against repeated
1654 invocation by setting clipboard_owner to NULL after calling
1657 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
1658 and term_ntproc to their modified signatures.
1660 * character.c (char_string, string_char): Remove calls to
1661 MAYBE_UNIFY_CHAR. See the discussion starting at
1662 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
1665 2012-09-25 Chong Yidong <cyd@gnu.org>
1667 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
1669 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
1671 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
1672 when encountering an unknown bytecode.
1674 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
1676 image.c, indent.c: Use bool for booleans.
1677 * dispextern.h (struct image_type): Members valid_p, load, init
1678 now return bool, not int. All uses changed.
1679 * image.c: Omit unnecessary static decls.
1680 (x_create_bitmap_mask, x_build_heuristic_mask):
1681 Return void, not int, since callers don't care about the return value.

1710 Use bool for booleans.
1712 2012-09-24 Chong Yidong <cyd@gnu.org>
1714 * chartab.c (Fset_char_table_default): Obsolete function removed.
1716 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
1718 Move pid_t related decls out of lisp.h.
1719 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
1720 (interruptible_wait_for_termination):
1721 Move these decls from lisp.h to syswait.h, since they use pid_t.
1722 Needed on FreeBSD; see Herbert J. Skuhra in
1723 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
1724 * callproc.c: Include syswait.h.

1744 Use bool for boolean.
1745 * gtkutil.c (xg_update_frame_menubar):

1770 2012-09-23 Eli Zaretskii <eliz@gnu.org>
1772 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
1773 fatal_error_backtrace.
1775 * w32proc.c (sys_kill): Undo last change: don't do anything when
1776 invoked to deliver SIGABRT to our own process. This is now
1777 handled by emacs_raise.
1779 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
1781 * w32term.c (w32_read_socket): Remove leftover reference to
1782 interrupt_input_pending.
1784 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
1786 Do not use SA_NODEFER.
1787 Problem reported by Dani Moncayo in
1788 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
1790 * sysdep.c (emacs_abort): Do not reset signal handler.
1791 * emacs.c (terminate_due_to_signal): Reset signal handler here.
1792 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
1793 wanted even on POSIXish hosts, and it doesn't work on Windows.
1795 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
1797 * xterm.c (x_term_init): Call fixup_locale before and after calling
1798 gtk_init (Bug#12392).
1800 2012-09-23 Chong Yidong <cyd@gnu.org>
1802 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
1803 Vdynamic_library_alist.
1805 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
1806 (Fgnutls_available_p): Caller changed.
1808 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
1809 (Flibxml_parse_xml_region): Likewise.
1811 * dispextern.h (struct image_type): Remove arg from init function.
1813 * image.c (Finit_image_library, lookup_image_type)
1814 (define_image_type): Remove now-unneeded second arg.
1815 (init_xpm_functions, init_png_functions, init_jpeg_functions)
1816 (init_tiff_functions, init_gif_functions, init_svg_functions):
1817 Arglist and w32_delayed_load calling convention changed.
1818 (gs_type): Remove init_gs_functions; there is no such function.
1819 (valid_image_p, make_image): Fix caller to lookup_image_type.
1821 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
1823 Simplify and avoid signal-handling races (Bug#12471).
1825 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
1826 Avoid recursive loop if there's a fatal error in the function itself.
1827 * atimer.c (pending_atimers):
1828 * blockinput.h: Don't include "atimer.h"; no longer needed.
1829 (interrupt_input_pending): Remove. All uses removed.
1830 pending_signals now counts both atimers and ordinary interrupts.
1831 This is less racy than having three separate pending-signal flags.
1832 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
1834 Rename from their upper-case counterparts BLOCK_INPUT,
1835 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
1836 INPUT_BLOCKED_P, and turn into functions. All uses changed.
1837 This makes it easier to access volatile variables more accurately.
1838 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
1839 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
1840 that's more reliable if the code is buggy and sets
1841 interrupt_input_blocked to a negative value. All uses changed.
1842 * atimer.c (deliver_alarm_signal):
1843 Remove. No need to deliver this to the parent; any thread can
1844 handle this signal now. All uses replaced by underlying handler.
1845 * atimer.c (turn_on_atimers):
1846 * dispnew.c (handle_window_change_signal):
1847 * emacs.c (handle_danger_signal):
1848 * keyboard.c (kbd_buffer_get_event):
1849 Don't reestablish signal handler; not needed with sigaction.
1850 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
1852 Rework to avoid unnecessary accesses to volatile variables.
1853 (UNBLOCK_INPUT_TO): Now a function.
1854 (totally_unblock_input, unblock_input): New decls.
1855 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
1856 (init_data): Remove. Necessary stuff now done in init_signal.
1857 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
1858 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
1859 (fatal_error_code): Remove; no longer needed.
1860 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
1861 it doesn't always backtrace. All uses changed. No need to reset
1862 signal to default, since sigaction and/or die does that for us now.
1863 Use emacs_raise (FOO), not kill (getpid (), FOO).
1864 (main): Check more-accurately whether we're dumping.
1865 Move fatal-error setup to sysdep.c
1866 * floatfns.c: Do not include "syssignal.h"; no longer needed.
1867 * gtkutil.c (xg_get_file_name, xg_get_font):
1868 Remove no-longer-needed signal-mask manipulation.
1869 * keyboard.c, process.c (POLL_FOR_INPUT):
1870 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
1871 * keyboard.c (read_avail_input): Remove.
1872 All uses replaced by gobble_input.
1873 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
1874 (kbd_buffer_store_event_hold, gobble_input):
1875 (record_asynch_buffer_change) [USABLE_SIGIO]:
1876 (store_user_signal_events):
1877 No need to mess with signal mask.
1878 (gobble_input): If blocking input and there are terminals, simply
1879 set pending_signals to 1 and return. All hooks changed to not
1880 worry about whether input is blocked.
1881 (process_pending_signals): Clear pending_signals before processing
1882 them, in case a signal comes in while we're processing.
1883 By convention callers now test pending_signals before calling us.
1884 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
1885 New functions, to support changes to blockinput.h.
1886 (handle_input_available_signal): Now extern.
1887 (reinvoke_input_signal): Remove. All uses replaced by
1889 (quit_count): Now volatile, since a signal handler uses it.
1890 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
1891 All callers changed. Block SIGINT only if not already blocked.
1892 Clear sigmask reliably, even if Fsignal returns, which it can.
1893 Omit unnecessary accesses to volatile var.
1894 (quit_throw_to_read_char): No need to restore sigmask.
1895 * keyboard.c (gobble_input, handle_user_signal):
1896 * process.c (wait_reading_process_output):
1897 Call signal-handling code rather than killing ourselves.
1898 * lisp.h: Include <float.h>, for...
1899 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
1900 (pending_signals): Now volatile.
1901 (syms_of_data): Now const if IEEE floating point.
1902 (handle_input_available_signal) [USABLE_SIGIO]:
1903 (terminate_due_to_signal, record_child_status_change): New decls.
1904 * process.c (create_process): Avoid disaster if memory is exhausted
1905 while we're processing a vfork, by tightening the critical section
1907 (send_process_frame, process_sent_to, handle_pipe_signal)
1908 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
1910 (send_process): No need for setjmp/longjmp any more, since the
1911 SIGPIPE stuff is now gone. Instead, report an error if errno
1913 (record_child_status_change): Now extern. PID and W are now args.
1914 Return void, not bool. All callers changed.
1915 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
1916 Remove. All uses removed. This bug should be fixed now in a
1918 (wait_for_termination_1): Use waitpid rather than sigsuspend,
1919 and record the child status change directly. This avoids the
1920 need to futz with the signal mask.
1921 (process_fatal_action): Move here from emacs.c.
1922 (emacs_sigaction_flags): New function, containing
1923 much of what used to be in emacs_sigaction_init.
1924 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
1925 caught by emacs, to make races less likely.
1926 (deliver_process_signal): Rename from handle_on_main_thread.
1928 (BACKTRACE_LIMIT_MAX): Now at top level.
1929 (thread_backtrace_buffer, threadback_backtrace_pointers):
1931 (deliver_thread_signal, deliver_fatal_thread_signal):
1932 New functions, for more-accurate delivery of thread-specific signals.
1933 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
1934 (deliver_arith_signal): Handle in this thread, not
1935 in the main thread, since it's triggered by this thread.
1936 (maybe_fatal_sig): New function.
1937 (init_signals): New arg DUMPING so that we can be more accurate
1938 about whether we're dumping. Caller changed.
1939 Treat thread-specific signals differently from process-general signals.
1940 Block all signals while handling fatal error; that's safer.
1941 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
1943 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
1944 Ignore SIGPIPE unless batch.
1945 (emacs_backtrace): Output backtrace for the appropriate thread,
1946 which is not necessarily the main thread.
1947 * syssignal.h: Include <stdbool.h>.
1948 (emacs_raise): New macro.
1949 * xterm.c (x_connection_signal): Remove; no longer needed
1950 now that we use sigaction.
1951 (x_connection_closed): No need to mess with sigmask now.
1952 (x_initialize): No need to reset SIGPIPE handler here, since
1953 init_signals does this for us now.
1955 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
1957 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
1958 background rect may be larger (Bug#12245).
1960 2012-09-23 Chong Yidong <cyd@gnu.org>
1962 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
1964 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
1966 * .gdbinit: Just stop at fatal_error_backtrace.
1967 See Stefan Monnier's request in
1968 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
1969 Remove no-longer-used query of system type.
1971 2012-09-22 Chong Yidong <cyd@gnu.org>
1973 * search.c (Freplace_match): Doc fix (Bug#12325).
1975 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
1977 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
1978 (Fline_end_position): Doc fix.
1980 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
1982 2012-09-22 Chong Yidong <cyd@gnu.org>
1984 * dispextern.h (struct image_type): Add new slot, storing a type
1985 initialization function.
1987 * image.c (define_image_type): Call the image initializer function
1988 if it is defined. Arguments and return value changed.
1989 (valid_image_p, make_image): Callers changed.
1990 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
1991 (gif_type, imagemagick_type, svg_type, gs_type):
1992 Add initialization functions.
1993 (Finit_image_library): Call lookup_image_type.
1994 (CHECK_LIB_AVAILABLE): Macro deleted.
1995 (lookup_image_type): Call define_image_type here, rather than via
1996 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
1997 (syms_of_image): Move define_image_type calls for xbm_type and
1998 pbm_type to lookup_image_type.
2000 2012-09-22 Eli Zaretskii <eliz@gnu.org>
2002 * keyboard.c (timer_check_2): Move calculation of 'timers' and
2003 'idle_timers' from here ...
2004 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
2005 lists, to avoid infloops when the timer does something stupid,
2006 like reinvoke itself with the same or smaller time-out.
2009 2012-09-22 Martin Rudalics <rudalics@gmx.at>
2011 * window.c (Fsplit_window_internal): Handle only Qt value of
2012 Vwindow_combination_limit separately.
2013 (Qtemp_buffer_resize): New symbol.
2014 (Vwindow_combination_limit): New default value.
2017 2012-09-22 Eli Zaretskii <eliz@gnu.org>
2019 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
2020 the new overlay string. (Bug#10159)
2022 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
2024 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
2025 or that fprintf is async-signal-safe. POSIX doesn't require
2028 2012-09-22 Chong Yidong <cyd@gnu.org>
2030 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
2033 2012-09-22 Kenichi Handa <handa@gnu.org>
2035 * composite.c (composition_reseat_it): Handle the case that a
2036 grapheme cluster is not covered by a single font (Bug#12352).
2038 2012-09-21 Chong Yidong <cyd@gnu.org>
2040 * image.c (define_image_type): Avoid adding duplicate types to
2041 image_types (Bug#12463). Suggested by Jörg Walter.
2043 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2045 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
2046 (print_load_command_name): Add case LC_DATA_IN_CODE.
2047 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
2049 2012-09-21 Glenn Morris <rgm@gnu.org>
2051 * eval.c (Frun_hook_with_args_until_success)
2052 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
2054 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
2056 * fileio.c (Ffile_selinux_context): Only call freecon when
2057 lgetfilecon succeeded.
2058 (Fset_file_selinux_context): Likewise. (Bug#12444)
2060 2012-09-21 Eli Zaretskii <eliz@gnu.org>
2062 * xdisp.c (try_window_reusing_current_matrix): Under bidi
2063 reordering, locate the cursor by calling set_cursor_from_row; if
2064 that fails, clear the desired glyph matrix before returning a
2065 failure indication to the caller. Fixes leaving garbled display
2066 when fast scrolling with a down-key. (Bug#12403)
2067 (compute_stop_pos_backwards): Fix a typo that caused crashes while
2068 scrolling through multibyte text.
2070 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
2072 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
2073 calling mark_vectorlike since that's the one that marks the window.
2074 (mark_discard_killed_buffers): Mark the final cdr.
2075 * window.h (struct window): Move prev/next_buffers to the
2076 non-standard fields.
2077 * window.c (make_window): Initialize prev/next_buffers manually.
2079 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
2081 Omit unused arg EXPECTED from socket hooks.
2082 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
2083 * nsterm.m (ns_term_init):
2084 * termhooks.h (struct terminal.read_socket_hook):
2085 * w32inevt.c (w32_console_read_socket):
2086 * w32term.c (w32_read_socket):
2087 * xterm.c (XTread_socket):
2088 Omit unused arg EXPECTED. All callers changed.
2089 (store_user_signal_events): Return void, not int, since callers no
2090 longer care about the return value. All uses changed.
2092 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
2094 * w32gui.h (XParseGeometry): Do not declare.
2096 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
2098 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
2099 Ignore 'expected'. See Eli Zaretskii in
2100 <http://bugs.gnu.org/12471#8> (last line).
2102 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
2103 (XParseGeometry): Now static. Substitute extremal values for
2104 values that are out of range.
2106 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
2108 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
2110 * nsfns.m (XParseGeometry): Remove.
2111 (Fx_create_frame): Call x_set_offset to correctly interpret
2112 top_pos in geometry.
2114 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
2115 (Fx_parse_geometry): If there is a space in string, call
2116 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
2118 2012-09-17 Eli Zaretskii <eliz@gnu.org>
2120 * search.c (scan_buffer): Use character positions in calls to
2121 region_cache_forward and region_cache_backward, not byte
2122 positions. (Bug#12196)
2124 * w32term.c (w32_read_socket): Set pending_signals to 1, like
2125 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
2127 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
2128 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
2129 emacs_blocked_malloc, now deleted.
2131 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
2133 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
2134 The workaround was for improving performance on Solaris 2.4, but
2135 is getting in the way now. Emacs will still work if someone is
2136 still running Solaris 2.4 in a museum somewhere; Sun dropped
2137 support for Solaris 2.4 in 2003.
2138 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
2139 * process.c (create_process) [HAVE_WORKING_VFORK]:
2140 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
2141 since Emacs no longer uses vfork on that platform.
2143 2012-09-17 Glenn Morris <rgm@gnu.org>
2145 * emacs.c: Use COPYRIGHT.
2147 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
2149 Remove configure's --without-sync-input option (Bug#12450).
2150 When auditing signal-handling in preparation for cleaning it up,
2151 I found that SYNC_INPUT has race conditions and would be a real
2152 pain to fix. Since it's an undocumented and deprecated
2153 configure-time option, now seems like a good time to remove it.
2154 Also see <http://bugs.gnu.org/11080#16>.
2155 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
2156 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
2157 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
2158 (malloc_hysteresis):
2159 (check_depth) [XMALLOC_OVERRUN_CHECK]:
2160 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
2161 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
2162 (dont_register_blocks, bytes_used_when_reconsidered)
2163 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
2164 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
2165 [!SYSTEM_MALLOC && !SYNC_INPUT]:
2166 Remove. All uses removed.
2167 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
2168 implementation, one that depends on whether the new macro
2169 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
2171 * atimer.c (run_timers, handle_alarm_signal):
2172 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
2173 (handle_async_input, process_pending_signals)
2174 (handle_input_available_signal, init_keyboard):
2175 * nsterm.m (ns_read_socket):
2176 * process.c (wait_reading_process_output):
2177 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
2178 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
2180 * xterm.c (XTread_socket):
2182 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
2183 * eval.c (handling_signal): Remove. All uses removed.
2184 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
2185 All uses replaced with the SYNC_INPUT version.
2186 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
2188 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2191 * font.c (Ffont_shape_gstring): Remove unused local.
2193 2012-09-16 Glenn Morris <rgm@gnu.org>
2195 * Makefile.in (clean): No longer run nextstep's clean.
2197 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
2199 (ns-app): Move here from ns.mk, and simplify.
2200 (clean): Simplify nextstep entry.
2201 * ns.mk: Remove file.
2203 2012-09-17 Kenichi Handa <handa@gnu.org>
2205 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
2206 not covert the last few charactes.
2208 2012-09-16 Kenichi Handa <handa@gnu.org>
2210 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
2211 here, but just check the validity of glyphs in the glyph-string.
2213 2012-09-16 Martin Rudalics <rudalics@gmx.at>
2215 * window.c (Fwindow_parameter, Fset_window_parameter):
2216 Accept any window as argument (Bug#12452).
2218 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
2220 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
2221 to ns_term_init to avoid memory leak.
2223 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
2224 explicit retain/release.
2225 (ns_term_init): Only allow one display. Initialize outerpool and
2228 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
2230 Port _setjmp fix to POSIXish hosts as well as Microsoft.
2231 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
2232 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
2233 the Microsoft problem in a different way, by altering ../nt/config.nt.
2235 2012-09-15 Eli Zaretskii <eliz@gnu.org>
2250 * w16select.c: Remove inclusion of setjmp.h, as it is now included
2251 by lisp.h. This completes removal of setjmp.h inclusion
2252 erroneously announced in the previous commit. (Bug#12446)
2254 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
2257 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
2258 not defined as a macro. The latter happens on MS-Windows.
2261 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
2263 Port better to POSIX hosts lacking _setjmp (Bug#12446).
2264 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
2265 Some instances of '#include <setjmp.h>' removed, if the
2266 only reason for the instance was because "lisp.h" was included.
2267 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
2268 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
2269 and _longjmp with the new symbols. Emacs already uses _setjmp if
2270 available, so this change affects only POSIXish hosts that have
2271 sigsetjmp but not _setjmp, such as some versions of Solaris and
2272 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
2273 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
2274 (png_load_body) [HAVE_PNG]:
2275 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
2276 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
2277 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
2278 since PNG requires jmp_buf. This is the only exception to the
2279 general rule that we now use sys_setjmp and sys_longjmp.
2280 This exception is OK since this code does not change the signal
2281 mask or longjmp out of a signal handler.
2283 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
2285 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
2286 Include "syssignal.h", for 'main_thread'.
2288 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
2290 Avoid out-of-range marker position (Bug#12426).
2291 * insdel.c (replace_range, replace_range_2):
2292 Adjust markers before overlays, as suggested by comments.
2293 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
2294 Remove redundant check before calling offset_intervals.
2296 2012-09-14 Martin Rudalics <rudalics@gmx.at>
2298 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
2299 current buffer (Bug#12387).
2301 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
2303 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
2305 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
2307 Use a more backwards-compatible timer format (Bug#12430).
2308 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
2309 vector element, not from the 4th, since PSECS is now at the end.
2310 (Fcurrent_idle_time): Doc fix.
2312 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
2314 Function to mark objects and remove killed buffers at once.
2315 * alloc.c (discard_killed_buffers): Rename to ...
2316 (mark_discard_killed buffers) ... new name. Add marking
2317 of remaining objects. Fix comment. Adjust users.
2318 (mark_object): Do not touch frame buffer lists here.
2319 * frame.c (delete_frame): Reset frame buffer lists here.
2321 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
2323 Better workaround for GNOME bug when --enable-gcc-warnings.
2324 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
2325 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
2326 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
2328 Simplify SIGIO usage (Bug#12408).
2329 The code that dealt with SIGIO was crufty and confusing, e.g., it
2330 played tricks like "#undef SIGIO" but these tricks were not used
2331 consistently. Simplify mostly by not #undeffing standard symbols,
2332 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
2333 or not as we please) rather than "defined SIGIO" (standard symbol
2334 that we probably shouldn't #undef).
2335 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
2336 Modules that need it can include it.
2337 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
2338 * dispextern.h (ignore_sigio): New decl.
2339 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
2340 unconditionally, since it's now a no-op if !USABLE_SIGIO.
2341 * emacs.c (shut_down_emacs):
2342 * keyboard.c (kbd_buffer_store_event_hold):
2343 Use ignore_sigio rather than invoking 'signal' directly.
2344 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
2346 (FIONREAD, SIGIO): Do not #undef.
2347 (tty_read_avail_input): Use #error rather than a syntax error.
2348 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
2349 for I_PIPE, used by SETUP_SLAVE_PTY.
2350 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
2351 * sysdep.c (croak): Remove; no longer needed. This bit of
2352 temporary code, with Fred N. Fish's comment that it's temporary,
2353 has been in Emacs since at least 1992!
2354 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
2355 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
2356 * syssignal.h (croak): Remove decl.
2357 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
2358 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
2359 now that we're termios-only.
2360 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
2361 * term.c (dissociate_if_controlling_tty): Use #error rather than
2364 Work around GCC and GNOME bugs when --enable-gcc-warnings.
2365 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
2366 to work around GNOME bug 683906.
2367 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
2368 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
2369 This works around GCC bug 54561.
2371 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
2373 More fixes for 'volatile' and setjmp/longjmp.
2374 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
2375 * image.c (struct png_load_context) [HAVE_PNG]: New type.
2376 (png_load_body) [HAVE_PNG]:
2377 (jpeg_load_body) [HAVE_JPEG]:
2378 New function, with most of the old parent function's body.
2379 (png_load) [HAVE_PNG]:
2380 (jpeg_load) [HAVE_JPEG]:
2381 Invoke the new function, to avoid longjmp munging our locals.
2382 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
2383 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
2384 longjmp is passed 2, as the C standard doesn't guarantee this.
2385 Instead, store the failure code into mgr->failure_code.
2387 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
2389 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
2390 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
2391 (syms_of_keyboard): Remove support for unread-command-char.
2393 2012-09-12 Eli Zaretskii <eliz@gnu.org>
2395 * w32proc.c (sys_kill): If PID is our process ID and the signal is
2396 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
2397 violation. (Bug#12426)
2399 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
2401 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
2403 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
2405 * eval.c: Add `inhibit-debugger'.
2406 (Qinhibit_debugger): New symbol.
2407 (call_debugger): Bind it instead of Qdebug_on_error.
2408 (maybe_call_debugger): Test Vinhibit_debugger.
2409 (syms_of_eval): Define inhibit-debugger.
2410 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
2411 (syms_of_xdisp): Remove inhibit-debug-on-message.
2413 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
2415 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
2416 If a nonvolatile local variable is written before a _longjmp to
2417 the frame containing the variable, and is read after the _longjmp,
2418 the value read is indeterminate. Some local variables of type
2419 'struct handler' and 'struct catchtag' are used in this way, so
2420 mark each of their slots as volatile if the slot can be set before
2421 _longjmp and read afterwards.
2422 * lisp.h (struct handler): var and chosen_clause are now volatile.
2423 (struct catchtag): val, next, and pdlcount are now volatile.
2425 * bidi.c (bidi_push_it, bidi_pop_it):
2426 * fns.c (copy_hash_table):
2427 * image.c (define_image_type):
2428 * keyboard.c (kbd_buffer_store_event_hold):
2429 * process.c (Fprocess_send_eof):
2430 * xfaces.c (x_create_gc) [HAVE_NS]:
2431 * xgselect.c (xg_select):
2432 Prefer assignment to memcpy when either will do.
2434 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
2435 Use pointer-to-a-pointer to simplify and avoid a NILP check each
2436 time an item is removed. No need to mark this function 'inline';
2437 the compiler knows better than we do.
2439 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
2441 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
2442 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
2443 to change_frame_size (Bug#12388).
2444 (windowDidResize:): Pass YES to updateFrameSize.
2446 * nsterm.h: Add delay parameter to updateFrameSize.
2448 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
2450 Discard killed buffers from deleted window and frame objects.
2451 This reduces an amount of references to killed buffers and
2452 helps GC to reclaim them faster.
2453 * alloc.c (discard_killed_buffers): New function.
2454 (mark_object): Use it for deleted windows and frames.
2455 (mark_object): If symbol's value is set up for a killed buffer
2456 or deleted frame, restore its global binding.
2457 * data.c (swap_in_global_binding): Add GC notice.
2458 (swap_in_symval_forwarding): Use convenient set_blv_where.
2459 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
2460 * window.h: ... to here.
2462 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
2464 Convenient macro to check whether the buffer is live.
2465 * buffer.h (BUFFER_LIVE_P): New macro.
2466 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
2467 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
2469 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2471 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
2472 composition cases (Bug#12364).
2474 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
2475 overhang of succeeding glyphs overlapping box cursor.
2477 * w32term.c (x_draw_glyph_string): Likewise.
2479 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
2481 Simplify, document, and port floating-point (Bug#12381).
2482 The porting part of this patch fixes bugs on non-IEEE platforms
2483 with frexp, ldexp, logb.
2484 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
2486 * floatfns.c: Simplify discussion of functions that Emacs doesn't
2487 support, by removing commented-out code and briefly listing the
2488 C89 functions excluded. The commented-out stuff was confusing
2489 maintenance, e.g., we thought we needed cbrt but it was commented out.
2490 (logb): Remove decl; no longer needed.
2491 (isfinite): New macro, if not already supplied.
2492 (isnan): Don't replace any existing macro.
2493 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
2494 are present on all C89 platforms.
2495 (Ffrexp): Do not special-case zero, as frexp does the right thing
2497 (Flogb): Do not use logb, as it doesn't have the desired meaning
2498 on hosts that use non-base-2 floating point. Instead, stick with
2499 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
2500 frexp, to avoid getting an unspecified result.
2502 * xdisp.c (Qinhibit_debug_on_message): Now static.
2504 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
2506 * nsterm.m (ns_update_begin): Set clip path to whole view by using
2507 NSBezierPath (Bug#12131).
2509 2012-09-10 Chong Yidong <cyd@gnu.org>
2511 * fns.c (Fdelq, Fdelete): Doc fix.
2513 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
2515 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
2516 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
2518 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
2520 * lisp.h (make_lisp_ptr): New macro to replace XSET.
2521 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
2524 2012-09-09 Eli Zaretskii <eliz@gnu.org>
2526 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
2527 left fringe if the window has a left margin. This avoids leaving
2528 traces of the cursor because its leftmost pixel is not drawn over.
2530 * dispnew.c (update_window_line): When the left margin area of a
2531 screen line is updated, set the redraw_fringe_bitmaps_p flag of
2532 that screen line. (Bug#12277)
2534 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
2536 Assume C89 or later for math functions (Bug#12381).
2537 This simplifies the code, and makes it a bit smaller and faster,
2538 and (most important) makes it easier to clean up signal handling
2539 since we can stop worring about floating-point exceptions in
2540 library code. That was a problem before C89, but the problem
2541 went away many years ago on all practical Emacs targets.
2542 * data.c, image.c, lread.c, print.c:
2543 Don't include <math.h>; no longer needed.
2544 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
2545 might be autoconfigured, as that never happens.
2547 * doprnt.c (DBL_MAX_10_EXP):
2548 * print.c (DBL_DIG):
2549 Remove. C89 or later always defines these.
2550 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
2551 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
2552 (arith_error, domain_error, domain_error2):
2553 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
2554 no longer needed -- we simply return what C returns. All uses removed.
2555 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
2557 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
2558 Remove. All uses expanded, as these macros are no longer used
2559 more than once and are now more trouble than they're worth.
2560 (Ftan): Use tan, not sin / cos.
2561 (Flogb): Assume C89 frexp.
2562 (fmod_float): Assume C89 fmod.
2563 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
2564 (init_floatfns): Remove. All uses removed.
2566 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2568 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
2569 compositeToPoint for OSX < 10.6 (Bug#12390).
2571 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
2573 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
2574 This produces more-accurate results.
2576 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2578 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
2579 changes (Bug#12088).
2581 2012-09-08 Chong Yidong <cyd@gnu.org>
2583 * syntax.c (Fstring_to_syntax): Doc fix.
2585 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2587 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
2588 in the internal border.
2589 (x_set_window_size): Remove static variables and their usage.
2590 (ns_redraw_scroll_bars): Fix NSTRACE arg.
2591 (ns_after_update_window_line, ns_draw_fringe_bitmap):
2592 Remove fringe/internal border adjustment (Bug#11052).
2593 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
2594 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
2595 (ns_fix_rect_ibw): Remove.
2596 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
2597 (ns_dumpglyphs_box_or_relief): Ditto.
2598 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
2600 (ns_dumpglyphs_image): Ditto.
2601 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
2603 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
2604 their usage. Add fringe_extended_p and its use as in other terms.
2605 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
2606 scroll bar was removed.
2607 (updateFrameSize): New function.
2608 (windowDidResize): Move code to updateFrameSize and call it.
2610 * nsterm.h (EmacsView): Add updateFrameSize.
2612 2012-09-07 Chong Yidong <cyd@gnu.org>
2614 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
2616 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
2618 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
2620 More signal-handler cleanup (Bug#12327).
2621 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
2622 Problem introduced when merging patches. Noted by Eli Zaretskii in
2623 <http://bugs.gnu.org/12327#67>.
2624 * floatfns.c: Comment fix.
2625 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
2626 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
2627 and anyway the declaration is harmless even if SIGDANGER is not defined.
2628 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
2629 defined BROKEN_FIONREAD). systty.h formerly did this, but other
2630 source files not surprisingly expected syssignal.h to define, or
2631 not define, SIGIO, and it's cleaner to do it that way, for consistency.
2632 Include <sys/ioctl.h>, for FIONREAD.
2633 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
2634 This eliminates a problem whereby other files mysteriously had
2635 to include "syssignal.h" before including "systty.h" if they
2636 wanted to use "#ifdef SIGIO".
2638 2012-09-07 Eli Zaretskii <eliz@gnu.org>
2640 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
2642 * w32.c (sigemptyset): Empty the set.
2643 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
2645 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
2647 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
2649 * alloc.c (mark_buffer): Revert unsafe marking optimization.
2650 (mark_object): Likewise for frame objects.
2652 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
2654 * syssignal.h (handle_on_main_thread): Always declare,
2655 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
2656 This ports to platforms without HAVE_PTHREAD.
2658 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
2660 Signal-handler cleanup (Bug#12327).
2661 Emacs's signal handlers were written in the old 4.2BSD style with
2662 sigblock and sigmask and so forth, and this led to some
2663 inefficiencies and confusion. Rewrite these to use
2664 pthread_sigmask etc. without copying signal sets around. Also,
2665 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
2666 'signal', and instead use functions that do not attempt to take
2667 over the system name space. This patch causes Emacs's text
2668 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
2669 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
2670 Do not include <signal.h> or "syssignal.h", as these
2671 modules do not use signals.
2672 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
2673 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
2674 Do not include <signal.h>, as "syssignal.h" does that for us now.
2675 * atimer.c (sigmask_atimers): New function.
2676 (block_atimers, unblock_atimers): New functions,
2677 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
2679 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
2680 no longer needed here.
2681 * emacs.c (main): Inspect existing signal handler with sigaction,
2682 so that there's no need to block and unblock SIGHUP.
2683 * sysdep.c (struct save_signal): New member 'action', replacing
2684 old member 'handler'.
2685 (save_signal_handlers, restore_signal_handlers):
2686 Use sigaction instead of 'signal' to save and restore.
2687 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
2688 New function. All users of 'signal' modified to use set_sighandler
2689 if they're writeonly, and to use sys_signal if they're read+write.
2690 (emacs_sigaction_init, forwarded_signal): New functions.
2691 (sys_signal): Remove. All uses replaced by calls to sigaction
2692 and emacs_sigaction_init, or by direct calls to 'signal'.
2693 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
2694 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
2695 all uses replaced by pthread_sigmask etc. calls.
2696 * syssignal.h: Include <signal.h>.
2697 (emacs_sigaction_init, forwarded_signal): New decls.
2698 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
2699 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
2700 (sigmask, sys_sigmask): Remove; no longer needed.
2701 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
2702 (sigblock, sigunblock, sigfree):
2703 (sigsetmask) [!defined sigsetmask]:
2704 Remove. All uses replaced by pthread_sigmask.
2705 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
2706 no longer need to be replaced, and its typical old uses
2707 are now done via emacs_sigaction_init and sigaction.
2708 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
2709 (sys_sigdel): Remove; unused.
2710 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
2712 2012-09-06 Eli Zaretskii <eliz@gnu.org>
2714 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
2715 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
2717 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
2719 Explicitly mark buffer_defaults and buffer_local_symbols.
2720 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
2721 mark_local_symbols here.
2722 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
2723 since special buffers aren't marked here any more.
2724 (allocate_buffer): Chain new buffer with all_buffers here...
2725 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
2727 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
2728 (syms_of_buffer): Remove staticpro of the above.
2729 (init_buffer_once): Set names for buffer_defaults and
2730 buffer_local_symbols.
2732 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
2734 Use bool for booleans in font-related modules.
2735 * font.c (font_intern_prop, font_style_to_value)
2736 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
2737 (generate_otf_features, font_check_otf_features, font_check_otf)
2738 (font_match_p, font_list_entities, font_at):
2739 * fontset.c (fontset_id_valid_p, reorder_font_vector
2740 (fontset_find_font, Fset_fontset_font)
2741 (face_suitable_for_char_p) [0]:
2742 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
2743 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
2744 (m17n_flt_initialized, ftfont_shape_by_flt):
2745 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
2746 * nsfont.m (nsfont_draw):
2747 * w32font.c (w32font_draw):
2748 * w32term.c (x_draw_glyphless_glyph_string_foreground):
2749 Use bool for booleans.
2750 * font.h: Adjust to above API changes.
2751 (struct font, struct font_driver, struct font_driver_list):
2752 Use bool for booleans.
2753 (struct font): Remove useless member encoding_type.
2755 * fontset.c, xftfont.c: Omit unnecessary static decls.
2757 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
2759 * alloc.c (mark_object): Revert window marking code
2760 since it's unsafe for the Fset_window_configuration.
2762 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
2764 Fix race conditions with signal handlers and errno (Bug#12327).
2765 Be more systematic about preserving errno whenever a signal
2766 handler returns, even if it's not in the main thread. Do this by
2767 renaming signal handlers to distinguish between signal delivery
2768 and signal handling. All uses changed.
2769 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
2770 * data.c (deliver_arith_signal): Rename from arith_error.
2771 * dispnew.c (deliver_window_change_signal): Rename from
2772 window_change_signal.
2773 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
2774 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
2775 * keyboard.c (deliver_input_available_signal): Rename from
2776 input_available_signal.
2777 (deliver_user_signal): Rename from handle_user_signal.
2778 (deliver_interrupt_signal): Rename from interrupt_signal.
2779 * process.c (deliver_pipe_signal): Rename from send_process_trap.
2780 (deliver_child_signal): Rename from sigchld_handler.
2781 * atimer.c (handle_alarm_signal):
2782 * data.c (handle_arith_signal):
2783 * dispnew.c (handle_window_change_signal):
2784 * emacs.c (handle_fatal_signal, handle_danger_signal):
2785 * keyboard.c (handle_input_available_signal):
2786 * keyboard.c (handle_user_signal, handle_interrupt_signal):
2787 * process.c (handle_pipe_signal, handle_child_signal):
2788 New functions, with the actual signal-handling code taken from the
2789 original respective signal handlers, sans the sporadic attempts to
2790 preserve errno, since that's now done by handle_on_main_thread.
2791 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
2792 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
2793 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2795 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2796 Move initialization of main_thread to sysdep.c's init_signals.
2797 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
2798 our usage, and simplifies the mainline code.
2799 (record_child_status_change): New static function, as a helper
2800 for handle_child_signal, and with most of the old child handler's
2802 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
2803 (handle_child_signal): Use the above.
2804 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2805 Moved here from emacs.c.
2806 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
2807 code moved here from emacs.c's main function.
2808 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
2809 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
2810 This lets callers save and restore errno properly.
2812 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2814 Remove redundant or unused things here and there.
2815 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
2816 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
2817 * editfns.c (Fcompare_buffer_substrings): Likewise.
2818 * frame.h (struct terminal, struct font_driver_list):
2819 Remove redundant declarations.
2820 * window.h (Qleft, Qright): Likewise.
2822 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2824 Do not mark objects from deleted buffers, windows and frames.
2825 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
2826 (mark_object): Likewise for windows and frames.
2828 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2830 * alloc.c (valid_lisp_object_p): Treat killed buffers,
2831 buffer_defaults and buffer_local_symbols as valid objects.
2832 Return special value to denote them.
2834 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
2836 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
2837 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
2838 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
2839 (file_name_absolute_p, Fsubstitute_in_file_name):
2840 (check_executable, check_writable, Ffile_accessible_directory_p)
2841 (Fset_file_selinux_context, Fdefault_file_modes)
2842 (Finsert_file_contents, choose_write_coding_system)
2843 (Fwrite_region, build_annotations, a_write, e_write)
2845 * filelock.c (boot_time_initialized, get_boot_time)
2846 (get_boot_time_1, lock_file_1, within_one_second):
2847 * floatfns.c (in_float):
2848 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
2849 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
2850 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
2851 * lisp.h (struct Lisp_Hash_Table.cmpfn):
2852 * window.c (compare_window_configurations):
2853 Use bool for booleans.
2854 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
2855 (Fdefault_file_modes): Now mode_t, not int, for modes.
2856 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
2857 (internal_delete_file): Now returns void, not a (boolean) int,
2858 since nobody was looking at the return value.
2859 * lisp.h, window.h: Adjust to above API changes.
2861 * xdisp.c (set_message): Simplify and reindent last change.
2863 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
2865 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
2867 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
2869 * eval.c (call_debugger): Make the function non-static so that we
2870 can call it from set_message.
2872 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
2873 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
2875 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2877 Give more-useful info on a fatal error (Bug#12328).
2878 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
2879 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
2880 of doing the work ourselves.
2881 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
2882 do most of the work.
2883 (fatal_error_backtrace): New function, taken from the guts
2884 of the old fatal_error_signal, but with a new option to output
2886 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
2887 info about the signal than just its number.
2888 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
2889 * sysdep.c: Include <execinfo.h>
2890 (emacs_backtrace): New function, taken partly from the previous
2891 code of the 'die' function.
2892 (emacs_abort): Call fatal_error_backtrace rather than abort.
2894 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
2896 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
2897 eager (load-time) macro-expansion.
2898 * lisp.mk (lisp): Add macroexp.
2900 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2902 Simplify redefinition of 'abort' (Bug#12316).
2903 Do not try to redefine the 'abort' function. Instead, redo
2904 the code so that it calls 'emacs_abort' rather than 'abort'.
2905 This removes the need for the NO_ABORT configure-time macro
2906 and makes it easier to change the abort code to do a backtrace.
2907 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
2908 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
2909 Remove; sysdep.c's emacs_abort now takes its place.
2910 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
2911 'abort' changed to use 'emacs_abort'.
2912 * msdos.c (dos_abort) [defined abort]: Remove; not used.
2913 (abort) [!defined abort]: Rename to ...
2914 (emacs_abort): ... new name.
2915 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
2916 the place of the old 'abort' in emacs.c.
2917 * w32.c, w32fns.c (abort): Do not #undef.
2918 * w32.c (emacs_abort): Rename from w32_abort.
2920 2012-09-04 Eli Zaretskii <eliz@gnu.org>
2922 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
2923 offsets[j].dv, since the y axis of the screen coordinates points
2924 down, while the y axis of the font definition coordinates points
2925 up. This fixes display of Arabic diacritics such as KASRA and
2926 KASRATAN. (Bug#11860)
2928 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2930 Be more systematic about _setjmp vs setjmp.
2931 * alloc.c (test_setjmp, mark_stack):
2932 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
2933 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
2934 (png_load, my_error_exit, jpeg_load):
2935 * process.c (send_process_trap, send_process):
2936 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
2937 The underscored versions are up to 30x faster on some hosts.
2938 Formerly, the code used setjmp+longjmp sometimes and
2939 _setjmp+_longjmp at other times, with no particular reason to
2940 prefer setjmp+longjmp.
2942 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
2944 Fix minor problem found by static checking.
2945 * buffer.c (Fdelete_all_overlays): Return nil.
2947 2012-09-03 Martin Rudalics <rudalics@gmx.at>
2949 * buffer.c (Fdelete_all_overlays): New function.
2951 2012-09-03 Chong Yidong <cyd@gnu.org>
2953 * gtkutil.c: Add extern decl for Qxft.
2955 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
2957 * emacs.c, eval.c: Use bool for boolean.
2958 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
2959 (malloc_using_checking) [DOUG_LEA_MALLOC]:
2960 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
2961 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
2962 (main, decode_env_path, Fdaemon_initialized):

2964 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
2965 (maybe_call_debugger, Fbacktrace):
2966 * process.c (read_process_output, exec_sentinel):
2967 Use bool for booleans.
2968 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
2969 All callers changed.
2970 * eval.c (interactive_p): Omit always-true boolean argument
2971 EXCLUDE_SUBRS_P. All callers changed.
2972 * dispextern.h, lisp.h: Reflect above API changes.
2973 * firstfile.c (dummy): Use the address of 'main', whose signature
2974 won't change, instead of the address of 'initialize', whose
2975 signature just changed from int to bool.
2976 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
2977 * msdos.c (fatal_error_in_progress): ... from here.
2978 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
2980 (redisplay_internal, unwind_redisplay): Simply clear
2981 REDISPLAYING_P when unwinding, instead of saving its previous,
2982 always-false value and then restoring it.
2984 Clean up some extern decls.
2985 Mostly, this hoists extern decls out of .c files and into .h files.
2986 That way, we're more likely to catch errors if the interfaces change.
2987 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
2988 declare xg_mark_data.
2989 * dispextern.h (x_frame_parm_handlers):
2991 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
2992 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
2993 (Qultra_bold, Qoblique, Qitalic):
2994 Move extern decl here from .c file.
2995 * alloc.c (xg_mark_data) [USE_GTK]:
2997 * eval.c (Qlexical_binding):
2998 * fns.c (time) [!HAVE_UNISTD_H]:

3004 * process.c (QCfamily, QCfilter):
3005 * widget.c (free_frame_faces):
3006 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
3007 * xfont.c (x_clear_errors):
3008 * xterm.c (x_frame_parm_handlers):
3009 Remove now-redundant extern decls.
3010 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
3011 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
3013 * xfaces.c: Remove unnecessary static decls.
3014 * xterm.c (updating_frame): Remove decl of nonexistent object.
3016 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
3017 when building globals.h, as the objects that are not built on
3018 this host are not needed to compile C files on this host.
3020 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
3022 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

3030 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
3031 (Fsubstitute_command_keys):

3033 (save_excursion_save, save_excursion_restore)
3034 (disassemble_lisp_time, decode_time_components, emacs_nmemftime)
3035 (format_time_string, general_insert_function)
3036 (make_buffer_string, make_buffer_string_both)
3037 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):
3038 * insdel.c (check_markers, gap_left, adjust_markers_for_insert)
3039 (copy_text, insert_1, insert_1_both, insert_from_string)
3040 (insert_from_string_before_markers, insert_from_string_1)

3049 (set_intervals_multibyte_1, set_intervals_multibyte):
3050 * keyboard.c (decode_timer):
3051 Use bool for boolean.
3052 * intervals.h, lisp.h, systime.h: Reflect above API changes.

3055 2012-09-02 Chong Yidong <cyd@gnu.org>
3057 * keymap.c (push_key_description): Print M-TAB as C-M-i
3060 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
3062 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
3063 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

3068 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
3070 2012-09-01 Eli Zaretskii <eliz@gnu.org>
3072 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
3073 more than one grapheme cluster passed to the shaper: compute the
3074 offset adjustment values separately for each cluster. (Bug#11860)
3076 * image.c: Restore mistakenly removed inclusion of w32.h. Without
3077 it, GCC doesn't see prototypes of w32_delayed_load, and complains
3078 about implicit conversions from integer to pointer.
3080 2012-09-01 Daniel Colascione <dancol@dancol.org>
3082 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
3083 system used too early.
3085 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
3087 Better seed support for (random).
3088 * emacs.c (main): Call init_random.
3089 * fns.c (Frandom): Set the seed from a string argument, if given.
3090 Remove long-obsolete Gentzel cruft.

3102 all of which have been moved to common code.
3104 * xfaces.c: Include TERM_HEADER instead of listing all possible
3105 window-system headers.
3107 * w32xfns.c (x_sync): Correct definition of x_sync (a no-op here)

3111 directly accessing frame internals.
3113 * w32font.h: Include font.h. Define syms_of_w32font and
3116 * process.c: Include TERM_HEADER instead of listing all possible
3117 window-system headers.
3119 * nsterm.h: Remove declarations now in frame.h.
3120 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
3122 * menu.c: Include TERM_HEADER instead of listing all possible
3123 window-system headers.
3125 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
3128 * keyboard.c: Include TERM_HEADER instead of listing all possible
3129 window-system headers.
3131 * image.c: Include TERM_HEADER instead of listing all possible
3132 window-system headers. Declare Vlibrary_cache when compiling for
3135 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
3136 window system declarations.
3138 * frame.h: Move common functions here: set_frame_menubar,
3139 x_set_window_size, x_sync, x_get_focus_frame,
3140 x_set_mouse_position, x_set_mouse_pixel_position,
3141 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

3161 * Makefile.in: Define WINDOW_SYSTEM_OBJ to hold objects needed for
3162 the current window system; include in list of objects to link into
3165 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
3167 Remove mark_ttys function and fix tty_display_info initialization.
3168 * lisp.h (mark_ttys): Remove prototype.
3169 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
3170 to mark_ttys because all possible values of 'top_frame' slot are
3171 the frames which are reachable from Vframe_list.
3172 * term.c (mark_ttys): Remove.
3173 (init_tty): Safely initialize 'top_frame' slot with Qnil.
3175 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
3177 Change struct frame bitfields from unsigned char to unsigned.
3178 * frame.h (struct frame): Change type of 'display_preempted',
3179 'visible', 'iconified', 'has_minibuffer', 'wants_modeline',
3180 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
3181 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
3182 bitfields from unsigned char to unsigned.
3184 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
3186 Remove unused member of struct x_output and struct w32_output.
3187 * xterm.h (struct x_output): Remove unused field 'needs_exposure'.
3188 * w32term.h (struct w32_output): Likewise.
3190 2012-08-30 Jan Djärv <jan.h.d@swipnet.se>
3192 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
3193 does not become zero (Bug#12234).
3195 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
3197 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
3198 for GCC 4.7.1 x86-64.
3200 2012-08-30 Glenn Morris <rgm@gnu.org>
3202 * lread.c (init_lread): For out-of-tree builds, only add the
3203 source directory's site-lisp dir to the load-path if it exists,
3204 consistent with in-tree builds. (Bug#12302)
3206 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
3208 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize
3209 button_values to NULL. Call setStykeMask so dialogs get a close button.
3210 (windowShouldClose:): Set window_closed.
3211 (dealloc): New member, free button_values.
3212 (process_dialog:): Make member function. Remove window argument,
3213 replace window with self. Count buttons and allocate and store values
3215 (addButton:value:row:): value is int with the name tag. Call setTag
3216 with tag. Remove return self, declare return value as void.
3217 (addString:row:): Remove return self, declare return value as void.
3218 (addSplit): Remove return self, declare return value as void.
3219 (clicked:): Remove return self, declare return value as void.
3220 Set dialog_return to button_values[seltag]. Code formatting change.
3221 (initFromContents:isQuestion:): Adjust call to process_dialog.
3222 Code formatting change.
3223 (timeout_handler:): Set timer_fired to YES.
3224 (runDialogAt:): Set timer_fired to NO.
3225 Handle click on close button as quit.
3227 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
3228 Add window_closed and button_values. Add void as return value for
3229 add(Button|String|Split). addButton takes int instead of Lisp_Object.
3230 Add process_dialog as new member.
3232 2012-08-28 Eli Zaretskii <eliz@gnu.org>
3234 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
3235 is not one of the heaps we manage. (Bug#12242)
3237 2012-08-28 Glenn Morris <rgm@gnu.org>
3239 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)
3241 2012-08-28 Martin Rudalics <rudalics@gmx.at>
3243 * window.c (Fset_window_configuration): Remove handling of
3244 auto-buffer-name window parameter. Install revision of reverted
3247 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>

3250 * buffer.c (Fset_buffer_major_mode): Signal an error
3251 if the buffer is dead.
3252 (Fother_buffer, other_buffer_safely): Remove redundant
3255 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
3257 Always use set_buffer_if_live to restore original buffer at unwind.
3258 * buffer.h (record_unwind_current_buffer): New function.
3259 * bytecode.c, dispnew.c, editfns.c, fileio.c, fns.c, insdel.c:
3260 * keyboard.c, keymap.c, minibuf.c, print.c, process.c, textprop.c:
3261 * undo.c, window.c: Adjust users.
3262 * buffer.c (set_buffer_if_live): Fix comment.
3264 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
3266 Fix usage of set_buffer_internal.
3267 * buffer.h (set_buffer_internal): Make it BUFFER_INLINE.
3268 * buffer.c (set_buffer_if_live): Use set_buffer_internal.
3269 * coding.c (decode_coding): Omit redundant test.
3270 * fileio.c (decide_coding_unwind): Likewise.
3271 * fns.c (secure_hash): Likewise.
3272 * insdel.c (modify_region): Likewise.
3273 * keyboard.c (command_loop_1): Likewise.
3274 * print.c (PRINTFINISH): Likewise.
3275 * xdisp.c (run_window_scroll_functions): Use set_buffer_internal.
3277 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>

3297 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
3298 and remove last int (actually boolean) argument, which was always 0.
3299 All callers changed.
3300 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
3301 * dispextern.h (struct composition_it): Use bool for boolean.
3302 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
3303 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
3304 * dired.c (file_name_completion):
3305 Use bool for boolean. (This was missed in an earlier change.)
3307 2012-08-27 Martin Rudalics <rudalics@gmx.at>
3309 * window.c (Fset_window_configuration): Revert first part of
3312 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
3314 * nsterm.h (NSPanel): New class variable dialog_return.
3316 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
3317 Initialize dialog_return.
3318 (windowShouldClose:): Use stop instead of stopModalWithCode.
3319 (clicked:): Ditto, and also set dialog_return (Bug#12258).
3320 (timeout_handler:): Use stop instead of abortModal. Send a dummy
3322 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when

3367 Use bool for booleans.
3368 * coding.h, lisp.h: Reflect above API changes.
3369 * coding.c: Remove unnecessary static function decls.
3370 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
3371 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
3372 not a boolean 'int', since callers never look at the return value.
3373 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
3374 * coding.h (decoding_buffer_size, encoding_buffer_size)
3375 (emacs_mule_string_char): Remove unused extern decls.
3376 (struct iso_2022_spec, struct coding_system):

3378 (struct emacs_mule_spec): Remove unused field 'full_support'.
3379 All initializations removed.
3380 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
3382 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
3384 Fix spare memory change (Bug#12286).
3385 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
3386 (valid_lisp_object_p): Likewise.
3388 2012-08-27 Martin Rudalics <rudalics@gmx.at>
3390 * window.c (Fset_window_configuration): Record any window's old
3391 buffer if it's replaced (see Bug#8789). If the new current
3392 buffer doesn't appear in the selected window, go to its old
3395 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
3397 Special MEM_TYPE_SPARE to denote reserved memory.
3398 * alloc.c (enum mem_type): New memory type.
3399 (refill_memory_reserve): Use new type for spare memory.
3400 This prevents live_cons_p and live_string_p from incorrect
3401 detection of uninitialized objects from spare memory as live.
3403 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
3406 * Makefile.in (.PHONY): versioclean -> versionclean.
3408 Remove unused external symbols.
3409 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
3410 * window.c (Qwindow_valid_p, decode_valid_window):
3411 Now static, not extern.
3412 * data.c (Qinterval): Remove; unused.
3413 (syms_of_data): Do not define 'interval'.
3414 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
3415 * window.h (decode_valid_window):
3418 * character.c, charset.c, chartab.c: Use bool for booleans.

3429 (map_sub_char_table):
3430 Use bool for boolean.
3431 * character.c (str_to_unibyte): Omit last boolean argument; it was
3432 always 0. All callers changed.
3433 * character.h, charset.h: Adjust to match previous changes.
3434 * character.h (char_printable_p): Remove decl of nonexistent function.
3435 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
3436 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
3437 are all boolean, so make them single-bit bitfields.
3439 * lisp.h (ASET): Remove attempt to detect side effects.
3440 It was meant to be temporary and it often doesn't work,
3441 because when IDX has side effects the behavior of IDX==IDX
3442 is undefined. See Stefan Monnier in
3443 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
3445 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
3447 * lisp.h (functionp): New function (extracted from Ffunctionp).
3448 (FUNCTIONP): Use it.
3449 * eval.c (Ffunctionp): Use it.
3451 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
3453 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
3454 as that's faster and simpler than static storage. Don't bother
3455 with the g_main_context_query overhead if g_main_context_pending
3456 says no events are pending.
3457 (gfds, gfds_size): Remove these static vars.
3458 (xgselect_initialize): Remove; no longer needed.
3459 All uses and decls removed.
3461 * emacs.c (fatal_error_signal_hook): Remove.
3462 All uses removed. This leftover from old code was always 0.
3464 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
3465 * casefiddle.c (casify_object, casify_region):
3466 * casetab.c (set_case_table):
3467 * category.c, category.h (word_boundary_p):
3468 * category.h (CHAR_HAS_CATEGORY):
3469 Use bool for booleans, instead of int.
3471 2012-08-25 Eli Zaretskii <eliz@gnu.org>
3473 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
3475 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
3477 On assertion failure, print backtrace if available.
3478 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
3479 (die) [ENABLE_CHECKING]: Print a backtrace if available.
3480 * Makefile.in (LIB_EXECINFO): New macro.
3483 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
3484 * bytecode.c (exec_byte_code):
3485 * callint.c (check_mark, Fcall_interactively):
3486 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
3487 (getenv_internal, sync_process_alive, call_process_exited):
3488 * lisp.h (USE_SAFE_ALLOCA):
3489 Use bool for booleans, instead of int.
3490 * lisp.h, process.h: Adjust prototypes to match above changes.
3491 * callint.c (Fcall_interactively): Don't assume the mark's
3492 offset fits in 'int'.
3494 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
3496 * buffer.c, buffer.h: Use bool for boolean.
3497 * buffer.c (reset_buffer_local_variables)

3503 (mmap_enlarge, mmap_set_vars):
3504 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
3505 Use bool for booleans, instead of int.
3506 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
3507 since the 1-or-0 return value is always ignored anyway.
3508 (mmap_initialized_p):
3509 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
3510 * buffer.h, lisp.h: Adjust prototypes to match above changes.
3512 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
3514 * bidi.c: Use bool for boolean.
3515 This is a bit more readable, and makes the text segment of bidi.o
3516 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
3517 Presumably it's faster too.
3518 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):

3523 (bidi_explicit_dir_char, bidi_level_of_next_char)
3524 (bidi_find_other_level_edge, bidi_move_to_visually_next):
3525 Use bool for booleans, instead of int.
3526 * dispextern.h (bidi_init_it, bidi_paragraph_init)
3527 (bidi_unshelve_cache): Adjust decls to match code.
3529 2012-08-23 Martin Rudalics <rudalics@gmx.at>
3531 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
3534 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
3536 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
3537 * atimer.h: Include <stdbool.h>.
3539 2012-08-22 Dan Nicolaescu <dann@gnu.org>
3541 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
3542 compile time tests instead of run time tests on systems that do
3544 (FRAME_MAC_P): Remove leftover from deleted code.
3545 * frame.c (syms_of_frame): Remove leftover from deleted code.
3547 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
3549 * nsterm.m (insertText:): Don't clear modifiers if code is space.
3551 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
3553 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
3554 Otherwise, the compiler complains about (A?B:C) where B is void
3555 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
3556 (fontset_add): Return void, for FONTSET_ADD.
3558 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3560 * alloc.c: Use bool for booleans.
3561 (gc_in_progress, abort_on_gc)
3562 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
3563 (dont_register_blocks) [GC_MALLOC_CHECK]:
3564 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.

3566 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
3567 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
3568 (mark_stack, valid_pointer_p, make_pure_string)
3569 (Fgarbage_collect, survives_gc_p, gc_sweep):
3570 Use bool for booleans, instead of int.
3571 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
3572 Remove unused local.
3573 * alloc.c (PURE_POINTER_P):
3574 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
3575 * editfns.c (Fformat):
3576 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
3578 * fns.c (sweep_weak_table):
3579 * lisp.h (suppress_checking, push_message, survives_gc_p)
3580 (make_pure_string, gc_in_progress, abort_on_gc):
3581 * lread.c (readchar, read1):
3582 * print.c (Fprin1_to_string):
3583 * xdisp.c (push_message):
3584 Use bool for booleans affected directly or indirectly by
3587 Make recently-introduced setters macros.
3588 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
3589 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
3590 (set_fontset_default, set_fontset_fallback): Rename from their
3591 upper-case counterparts, and make them functions rather than macros.
3592 This is more consistent with the other recently-introduced setters.
3593 These don't need to be inline, since they're local.
3595 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
3597 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
3598 the loop (Bug#12247).
3600 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3602 * lisp.h (vcopy): Use memcpy rather than our own loop.
3603 This fixes a performance regression introduced by the recent
3604 addition of vcopy. This means 'vcopy' will need to be modified
3605 for a copying collector, but that's OK. Also, tighten the
3606 checking in the assertion.
3608 2012-08-21 Eli Zaretskii <eliz@gnu.org>
3610 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
3611 components for RTL text (Bug#11860). Adjust X-OFFSET of each
3612 non-base glyph for the width of the base character, according to
3613 what x_draw_composite_glyph_string_foreground expects.
3614 Generate WADJUST value according to composition_gstring_width's
3615 expectations, to produce correct width of the composed character.
3616 Reverse the sign of the DU offset produced by ScriptPlace.
3618 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3620 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
3622 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
3624 Avoid direct writes to contents member of struct Lisp_Vector.
3625 * lisp.h (vcopy): New function to copy data into vector.
3626 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
3627 * fns.c (Ffillarray): Use ASET.
3628 * keyboard.c (timer_check_2): Use AREF and ASET.
3629 (append_tool_bar_item, Frecent_keys): Use vcopy.
3630 * lread.c (read_vector): Use ASET.
3631 * msdos.c (Frecent_doskeys): Use vcopy.
3632 * xface.c (Finternal_copy_lisp_face): Use vcopy.
3633 (Finternal_merge_in_global_face): Use ASET and vcopy.
3634 * xfont.c (xfont_list_pattern): Likewise.
3636 2012-08-21 Martin Rudalics <rudalics@gmx.at>

3702 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
3704 Rely on <config.h> + <unistd.h> to declare 'environ',
3705 as gnulib does this if the system doesn't.
3706 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:

4575 2012-08-04 Eli Zaretskii <eliz@gnu.org>
4577 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
4578 * w32.c (init_environment): Change the default values of many
4579 environment variables in dflt_envvars[] to NULL, to avoid pushing
4580 them into environment when they were not already defined.
4581 Remove the code that deletes site-lisp subdirectories from the default
4582 value of EMACSLOADPATH, as it is no longer needed.
4583 (check_windows_init_file): Now external, not static.
4584 Use Vload_path as is, without adding anything, as this function is now
4585 called when Vload_path is already set up.
4587 * w32.h (check_windows_init_file): Add prototype.
4589 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
4590 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
4591 compatibility with Posix platforms.
4592 (main): Move the call to check_windows_init_file to here from
4594 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
4595 any, in the DEFALT argument into the root of the Emacs build or
4596 installation tree, as appropriate.
4598 * callproc.c (init_callproc_1): Call decode_env_path instead of
4599 doing its equivalent by hand.
4600 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
4601 the code that sets Vexec_path run on MS-Windows.
4603 * lread.c (init_lread): Add comments to #ifdef's.
4605 * msdos.c (dos_set_window_size, IT_update_begin)
4606 (IT_frame_up_to_date, IT_set_frame_parameters): Use FVAR and WVAR
4607 instead of direct references.

4612 * lisp.h (DEFAULT_REHASH_THRESHOLD, DEFAULT_REHASH_SIZE):
4613 Now constants, not macros.
4615 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
4617 Remove unnecessary casts involving pointers.
4618 These casts are no longer needed now that we assume C89 or later,
4619 since they involve casting to or from void *.
4620 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
4621 (make_pure_float, make_pure_vector):
4622 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

4631 (x_get_window_property, x_get_window_property_as_lisp_data):
4632 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
4633 Remove unnecessary pointer casts.
4634 * alloc.c (record_xmalloc): New function.
4635 * lisp.h (record_xmalloc): New decl.
4636 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
4637 more like a function. This is because the pointer cast is not
4638 needed. All uses changed.
4639 * print.c (print_string, print_error_message): Avoid length recalc.
4641 Improve fix for macroexp crash with debugging (Bug#12118).
4642 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
4643 ARRAY_MARK_FLAG when checking subscripts, because ASET is
4644 not supposed to be invoked from the garbage collector.
4645 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
4646 (gc_aset): New function, which is like ASET but can be
4647 used in the garbage collector.
4648 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

4661 (map_w32_filename): Improve commentary. Simplify switch.
4662 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
4663 headers (most versions of MinGW w32api don't).
4664 (get_security_info, create_symbolic_link)
4665 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
4667 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
4668 in the argument file name.

4671 (sys_rename): Diagnose renaming of a symlink when the user doesn't
4672 have the required privileges.
4673 (get_file_security_desc_by_name): Rename from
4674 get_file_security_desc.

4676 with addition of handling of symlinks and support for 'lstat'.
4677 If possible, get file's attributes and security information by
4678 handle, not by name. Produce S_IFLNK bit for symlinks, when
4679 called from 'lstat'.
4680 (stat, lstat): New functions, call 'stat_worker'.
4681 (symlink, readlink, careadlinkat): Rewritten to create and resolve
4682 symlinks when the underlying filesystem supports them.
4684 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
4686 Fix macroexp crash on Windows with debugging (Bug#12118).
4687 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
4688 checking subscripts; problem introduced with the recent
4689 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
4690 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
4691 since it's used in non-static inline functions now.
4693 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
4694 Don't assume buffer size fits in 'int'. Remove unused local.

4712 * character.c (CHARACTER_INLINE):
4713 * charset.c (CHARSET_INLINE):
4714 * composite.c (COMPOSITE_INLINE):
4715 * dispnew.c (DISPEXTERN_INLINE):
4716 * sysdep.c (SYSTIME_INLINE):
4717 Define to EXTERN_INLINE, so that the corresponding functions
4718 are compiled into code.
4719 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
4720 (INLINE_HEADER_END): New macros.
4721 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

4743 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
4745 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
4746 This how ASET and AREF are supposed to work, and makes
4747 it easier to think about future improvements. See
4748 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
4749 * charset.h (set_charset_attr): New function.

5002 * s/aix4-2.h (sigmask): No need to undefine it, since syssignal.h
5003 does that unconditionally. Remove file, which is now empty.
5005 * s/freebsd.h, s/gnu-linux.h, s/sol2-6.h, s/unixware.h:
5008 2012-07-30 Paul Eggert <eggert@cs.ucla.edu>

5126 * w32inevt.c: Include w32inevt.h.
5127 (w32_read_console_input): New inline function, calls either
5128 ReadConsoleInputA or ReadConsoleInputW, depending on the value of
5129 w32_console_unicode_input.
5130 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
5131 (w32_kbd_patch_key, key_event): Use the codepage returned by
5132 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.

5164 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
5165 enumeration constants, as PURE and HEAP are too general, and clash
5166 with other headers and sources, such as gmalloc.c and the
5167 MS-Windows system headers. All users changed.
5169 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
5171 Revert last save_excursion_save and save_excursion_restore changes.
5172 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

5182 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
5184 Improve GDB symbol export (Bug#12036).
5185 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
5186 arms of an 'if', not using conditional expressions; otherwise GDB
5187 complains about the types in the unevaluated arm when the argument
5188 is an integer literal.
5189 (xgetint): Simplify expression.
5190 * alloc.c (gdb_make_enums_visible): New constant. This ports to
5191 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
5192 Zaretskii in <http://bugs.gnu.org/12036#13>.
5193 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
5194 needed now that we have gdb_make_enums_visible.
5195 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
5196 (enum enum_USE_LSB_TAG):
5197 New enum types, packaging up enums that need to be exported to GDB.

5216 * xfns.c (syms_of_xfns): Likewise.
5218 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
5220 Fast save_excursion_save and save_excursion_restore.
5221 * lisp.h (struct Lisp_Excursion): New data type.
5222 (PVEC_EXCURSION): New pseudovector type.
5223 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
5224 to deal with it. Adjust comments.

5238 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
5239 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
5240 emacs.c, as this is a more-suitable home. Had this been done earlier
5241 the fix for 12036 would have avoided some of the problems noted in
5242 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
5243 would have been more obvious.
5244 * emacs.c: Do not include <verify.h>; no longer needed.
5245 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
5246 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
5247 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
5248 Remove; now done in lisp.h.

5253 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
5254 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
5255 not be usable in #if. This simplifies things.
5257 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
5259 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
5261 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

5264 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
5265 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
5266 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
5267 Adjust to changes in lisp.h and emacs.c, by using
5268 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
5269 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
5270 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
5271 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
5272 instead of gdb_valbits.
5273 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
5274 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
5275 instead of gdb_array_mark_flag.
5276 (xboolvector): Get size from $->size, not $->header.size.
5277 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
5278 (xreload, hook-run, hookpost-run): Remove.
5279 * emacs.c: Include <verify.h>.
5280 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
5281 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
5283 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
5284 (gdb_USE_LSB_TAG): New enum constants.
5285 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
5286 Also define these as enum constants, so they're visible to GDB.
5287 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
5288 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
5289 as constants, so they're visible to GDB.
5290 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
5291 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
5292 Now enum constants, not macros, so they're visible to GDB.
5293 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
5294 more convenient now. All uses changed.
5295 (VALMASK) [USE_LSB_TAG]: Also define in this case.
5296 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
5298 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
5300 Explicitly free restriction data that are not needed anymore.
5301 * editfns.c (save_restriction_restore): Free restriction data.
5303 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
5305 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
5306 add argument, tune behavior, and adjust all callers.
5308 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
5310 Use typedef for EMACS_INT, EMACS_UINT.
5311 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
5312 than macros. This simplifies debugging in the usual case, since
5313 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
5314 and it allows expressions involving EMACS_INT casts.
5315 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
5317 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

5325 that FOCUS-FRAME can be omitted.
5327 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
5329 Adjust buffer text indirection counters at the end of Fkill_buffer.
5330 * buffer.c (Fkill_buffer): Adjust indirection counters when the
5331 buffer is definitely dead. This should really fix an issue reported
5332 by Christoph Scholtes again. (Bug#12007).
5333 (init_buffer_once): Initialize indirection counters of
5334 buffer_defaults and buffer_local_symbols (for sanity and safety).
5336 2012-07-24 Eli Zaretskii <eliz@gnu.org>
5338 * xdisp.c (init_iterator): Don't compute dimensions of truncation
5339 and continuation glyphs on tooltip frames, leave them at zero.
5340 Avoids continued lines in tooltips. (Bug#11832)
5342 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
5344 Simplify copy_overlay.
5345 * buffer.c (copy_overlay): Simplify. Use build_marker.

5351 or invalid. (Bug#12025)
5353 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
5354 it signals an error when a tooltip frame is being created.
5356 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
5358 Cleanup miscellaneous objects allocation and initialization.
5359 * alloc.c (allocate_misc): Change to static. Add argument to
5360 specify the subtype. Adjust comment and users.
5361 (build_overlay): New function.
5362 * buffer.c (copy_overlays, Fmake_overlay): Use it.
5363 * lisp.h (struct Lisp_Overlay): Remove obsolete comment.
5364 (allocate_misc): Remove prototype.
5365 (build_overlay): Add prototype.
5367 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
5369 Swap buffer text indirection counters in Fbuffer_swap_text.
5370 * buffer.c (Fbuffer_swap_text): Swap indirections too.
5371 This avoids crash reported by Christoph Scholtes at
5372 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
5374 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
5376 * nsmenu.m (Popdown_data): New struct.
5377 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
5379 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
5380 (initWithContentRect): Make imgView and contentView non-static
5381 and autorelease them. Also autorelease img and matrix (Bug#12005).
5382 (dealloc): Remove (Bug#12005).
5384 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
5386 Adjust consing_since_gc when objects are explicitly freed.
5387 * alloc.c (GC_DEFAULT_THRESHOLD): New macro.
5388 (Fgarbage_collect): Use it. Change minimum to 1/10 of default.
5389 (free_cons, free_misc): Subtract object size from consing_since_gc.
5391 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>

6130 * s/aix4-2.h (unix): Remove; no longer needed.
6132 EMACS_TIME simplification (Bug#11875).
6133 This replaces macros (which typically do not work in GDB)

6135 The functional style also makes code easier to read and maintain.
6136 * systime.h: Include <sys/time.h> on all hosts, not just if
6137 WINDOWSNT, since 'struct timeval' is needed in general.

6177 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
6178 Prefer snprintf to strncpy.
6179 * nsterm.m (ns_term_init):
6180 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
6181 * nsterm.m (ns_term_init):
6182 Avoid the need for strncpy, by using build_string or
6183 make_unibyte_string directly. Use dtoastr, not snprintf.
6184 * process.c (Fmake_network_process): Diagnose service names that
6185 are too long, rather than silently truncating them or creating
6186 non-null-terminated names.
6187 (Fnetwork_interface_info): Likewise, for interface names.
6188 * sysdep.c (system_process_attributes) [GNU_LINUX]:
6189 Prefer sprintf to strncat.

6203 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
6204 where argument type is known to be a Lisp_Cons.

6220 the function is called with compile-time constant argument.
6221 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
6222 argument, adjust users accordingly. Use build_pure_c_string where

6256 We include usg5-4-common.h, which defines them both.
6258 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
6259 O_RDONLY already includes it).
6261 Stop ns builds setting the EMACSLOADPATH environment variable.
6262 * nsterm.m (ns_load_path): Rename from ns_init_paths.
6263 Now it does not set EMACSLOADPATH, just returns the load-path string.
6264 * nsterm.h: Update accordingly.
6265 * lread.c [HAVE_NS]: Include nsterm.h.
6266 (init_lread) [HAVE_NS]: Use ns_load_path.

6276 (ns_init_paths): Do not set EMACSPATH.
6277 * nsterm.h (ns_exec_path): Add it.

6298 Declare the dummy function with ATTRIBUTE_CONST.
6299 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
6300 Add decls with ATTRIBUTE_CONST.
6302 Minor improvements to make_formatted_string.
6303 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
6304 where int is good enough, as vsprintf returns an int.
6305 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
6307 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
6309 Use make_formatted_string to avoid double length calculation.

6316 * frame.c (make_terminal_frame, set_term_frame_name)
6317 (x_report_frame_params): Likewise.

6330 * nsterm.h (ns_etc_directory): Add it.
6331 * callproc.c [HAVE_NS]: Include nsterm.h.
6332 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
6334 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
6336 Move marker debugging code under MARKER_DEBUG.
6337 * marker.c (MARKER_DEBUG): Move marker debugging code under
6338 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
6339 for bootstrap with --enable-checking (~3x slowdown reported
6340 by Juanma Barranquero <lekktu@gmail.com>).
6341 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
6343 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
6345 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
6346 See <http://bugs.gnu.org/11825#29>.
6348 2012-07-08 Eli Zaretskii <eliz@gnu.org>
6350 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
6351 has no font, use the frame's font. (Bug#11813)
6352 (display_line): Add commentary about displaying truncation glyphs
6354 (produce_special_glyphs): Move here from term.c.
6356 * term.c (produce_special_glyphs): Move to xdisp.c.
6358 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
6361 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>

6366 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
6368 * lisp.h: Remove empty conditional.
6370 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
6372 * lread.c (load_path_check): Now static.
6374 Fix some minor --with-ns problems found by static checking.
6375 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
6376 (x_set_font) [!HAVE_X_WINDOWS]:
6377 * image.c (xpm_load_image) [HAVE_NS]:
6378 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
6379 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
6380 Remove unused local.
6381 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
6382 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
6383 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
6384 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
6385 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
6386 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:

6389 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
6391 2012-07-07 Glenn Morris <rgm@gnu.org>
6393 * lread.c (load_path_check): New function, split from init_lread.
6394 (init_lread): Reorganize. Motivation:
6395 If EMACSLOADPATH is set, check/warn about that rather than the
6396 defaults, which we are not going to use. Hence we can remove
6397 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
6398 Don't warn if site-lisp directories are missing.
6399 If not installed, start from a blank load-path, since
6400 PATH_LOADSEARCH refers to the eventual installation directories.
6402 2012-07-07 Eli Zaretskii <eliz@gnu.org>
6404 Support truncation and continuation glyphs on GUI frames, when
6405 fringes are disabled. (Bug#11832)
6406 * xdisp.c (init_iterator): Get dimensions of truncation and
6407 continuation glyphs even if on GUI frames.
6408 Adjust it->last_visible_x on GUI frames when the left or right fringes,
6409 or both, are absent.
6410 (start_display, move_it_in_display_line_to): Handle the case of a
6411 GUI frame without a fringe to display continuation or truncation
6413 (insert_left_trunc_glyphs): Support GUI frames: make sure
6414 truncation glyphs overwrite enough glyphs from the current line to
6415 have sufficient space in pixels.
6416 (display_line): Support truncation and continuation glyphs on GUI
6417 frames. If some spare pixels are left on the line after inserting
6418 the truncation glyphs, fill that space with a stretch glyph of a
6419 suitably computed width.
6421 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
6422 produce_glyphs, to support GUI sessions.
6424 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
6426 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
6428 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
6430 Do not require float-time's arg to fit in time_t (Bug#11825).
6431 This works better on hosts where time_t is unsigned, and where
6432 float-time is applied to the (negative) difference between two times.
6433 * editfns.c (decode_time_components): Last arg is now double *,
6434 not int *, and means to store all the result as a double, without
6435 worrying about whether the seconds part fits in time_t.
6436 All callers changed.
6437 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
6438 All callers changed.
6439 (Ffloat_time): Do not fail merely because the specified time falls
6440 outside of time_t range.
6442 2012-07-07 Glenn Morris <rgm@gnu.org>
6444 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

6451 Update dependencies.
6453 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
6455 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6457 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

6459 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
6460 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
6461 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.

6464 * xfont.c (compare_font_names): Redo to omit the need for casts.
6466 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
6468 * xfns.c (Fx_change_window_property): Doc fix.
6469 * w32fns.c (Fx_change_window_property): Doc fix.
6471 * w32fns.c (Fx_window_property): Accept the same arguments as the
6472 X Windows version. Doc fix.
6473 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
6475 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
6476 Eli Zaretskii <eliz@gnu.org>
6478 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
6479 Windows-specific code from nt/config.nt moved here.
6480 Obsolete settings removed.
6482 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6484 * process.c: Avoid unnecessary calls to gettime.
6485 (wait_reading_process_output): Don't get the time of day
6486 when gobbling data immediately and not waiting, as there's no need
6487 for it in that case. This removes a FIXME.
6489 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
6491 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
6492 is defined (Bug#11768).
6494 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6496 Fix marker debugging code.
6497 * marker.c (byte_char_debug_check): Do not perform the check
6498 if buffer is not multibyte.
6499 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
6500 Call byte_char_debug_check with correct arguments.
6502 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6504 Compile marker debugging code only if ENABLE_CHECKING is defined.
6505 * marker.c (byte_char_debug_check, count_markers):
6506 Use only if ENABLE_CHECKING is defined.
6507 (byte_debug_flag): Remove.
6508 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
6509 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
6511 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6513 Avoid code repetition in marker-related functions.
6514 * marker.c (attach_marker): New function.
6515 (Fset_marker, set_marker_restricted, set_marker_both)
6516 (set_marker_restricted_both): Use it.
6517 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
6518 Consistently rename charno to charpos.

6536 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
6537 (save_restriction_save): Use build_marker.
6538 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
6539 * window.c (save_window_save): Likewise.
6541 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6543 Do not use Fdelete_overlay in delete_all_overlays
6544 to avoid redundant calls to unchain_overlay.
6545 * buffer.c (drop_overlay): New function.
6546 (delete_all_overlays, Fdelete_overlay): Use it.
6547 * minibuf.c (get_minibuffer): Fix comment.
6549 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6551 Port to OpenBSD 5.1 amd64.
6552 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
6553 This is needed for OpenBSD, and should be harmless on all BSD systems.
6554 Also, include <sys/sysctl.h>, as it should be available on all
6555 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
6556 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
6557 use p_pid member, not kp_proc.pid.
6559 2012-07-06 Glenn Morris <rgm@gnu.org>
6561 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
6563 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
6565 More xmalloc and related cleanup.
6566 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
6567 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

6574 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
6576 Omit needless casts involving void * pointers and allocation.
6577 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
6578 as the former is more robust if P's type is changed.
6579 Prefer xzalloc to xmalloc + memset 0.
6580 Simplify malloc-or-realloc to realloc.
6581 Don't worry about xmalloc returning a null pointer.
6582 Prefer xstrdup to xmalloc + strcpy.
6583 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
6585 * keyboard.c (apply_modifiers_uncached): Prefer local array to
6586 alloca of a constant.
6588 2012-07-05 Eli Zaretskii <eliz@gnu.org>
6590 * xdisp.c (display_line): Fix horizontal pixel coordinates when
6591 hscroll is larger than the line width. Fixes long and futile
6592 looping inside extend_face_to_end_of_line (on a TTY) producing
6593 glyphs that are not needed and thrown away.
6595 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
6597 * marker.c (set_marker_restricted_both): Simplify by using

6612 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
6613 (update_theme_scrollbar_width, xg_create_scroll_bar):
6614 Use gtk_scrollbar_new (Bug#11768).

6617 (xg_tool_item_stale_p): Call is_box_type.
6618 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
6619 with default display (Bug#11768).

6623 * xdisp.c (window_hscroll_limited): New function.
6624 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
6625 coordinates when window's hscroll is set to insanely large
6628 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
6630 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

6697 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
6698 This should be fixed in a better way; see Eli Zaretskii in
6699 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
6700 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
6702 * fileio.c (time_error_value): Rename from special_mtime.
6703 The old name's problems were noted by Eli Zaretskii in
6704 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
6706 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
6707 This variable's comment says Emacs needs at least one GDB-visible
6708 symbol of type enum pvec_type, to work around GDB problems.
6709 The symbol's value doesn't matter.
6711 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
6712 that causes compilation to fail on pre-C99 compilers.
6714 2012-07-04 Juanma Barranquero <lekktu@gmail.com>

6742 abusing vector->header.next.nbytes.
6743 (live_vector_p): Use PVEC_TYPE.
6744 (mark_object): Adapt code to extract pvectype. Use switch.
6746 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6748 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
6749 Tighten new eassert a bit.
6751 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6753 Fix compilation with --enable-gcc-warnings and -O1
6755 * doprnt.c (doprnt): Change type of tem to int, initialize
6756 to avoid compiler warning. Add eassert.
6757 * search.c (simple_search): Initialize match_byte to avoid
6758 compiler warning. Add eassert.
6760 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6762 Avoid weird behavior with large horizontal scrolls.
6763 Without this change, for example, large hscroll values would
6764 mess up Emacs's display on Fedora 15 x86, presumably due to
6765 overflows in int calculations in the display code.
6766 Also, if buffers had long lines, Emacs would freeze.
6767 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
6768 (set_window_hscroll): New function, containing the old guts of
6769 Fset_window_hscroll. Return the clipped value.
6770 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
6771 This avoids the need to check against PTRDIFF_MAX.
6773 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
6775 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6777 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
6779 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6781 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
6782 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
6783 since GCC 4.4.6 issues a bogus warning for them.
6785 Fix bugs in file timestamp newness comparisons.
6786 * fileio.c (Ffile_newer_than_file_p):
6787 * lread.c (Fload): Use full timestamp resolution of files,
6788 not just the 1-second resolution, so that files that are only
6789 slightly newer still count as newer.
6790 * fileio.c (Ffile_newer_than_file_p): Don't assume file
6791 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
6793 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
6795 * fileio.c: Improve handling of file time marker. (Bug#11852)
6796 (special_mtime): New function.
6797 (Finsert_file_contents, Fverify_visited_file_modtime):
6798 Use it to set special mtime values consistently.
6800 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
6802 * fileio.c (Finsert_file_contents): Properly handle st_mtime
6803 marker for non-existing file. (Bug#11852)
6805 2012-07-03 Glenn Morris <rgm@gnu.org>
6807 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
6808 and did not make it into globals.h).
6810 2012-07-03 Tom Tromey <tromey@redhat.com>
6812 * window.c (Fset_window_margins, Fset_window_fringes)

6848 2012-07-03 Glenn Morris <rgm@gnu.org>
6850 * lisp.h (Frandom): Make it visible to C.

6852 buffer for invisible buffers. (Bug#1229)
6854 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6856 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
6857 values which aren't power of 2.
6858 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
6859 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
6862 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
6864 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
6866 * alloc.c (mark_object): Revert part of last patch to use `switch'.
6868 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6870 * alloc.c (allocate_vector_block): Remove redundant
6871 calls to mallopt if DOUG_LEA_MALLOC is defined.
6872 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
6873 avoid calls to mallopt if zero_vector is returned.
6875 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6877 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
6878 is enabled, avoid dereferencing NULL current_sblock if
6881 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6883 Cleanup basic buffer management.
6884 * buffer.h (struct buffer): Change layout to use generic vector
6885 marking code. Fix some comments. Change type of 'clip_changed'
6886 to bitfield. Remove unused #ifndef old.
6887 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
6888 (GET_OVERLAYS_AT): Fix indentation.
6889 (for_each_per_buffer_object_at): New macro.
6890 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
6891 (Fbuffer_local_variables): Use it.
6892 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
6893 * alloc.c (allocate_buffer): Adjust to match new layout of
6894 struct buffer. Fix comment.
6895 (mark_overlay): New function.
6896 (mark_buffer): Use it. Use mark_vectorlike to mark normal
6897 Lisp area of struct buffer.
6898 (mark_object): Use it. Adjust marking of misc objects
6899 and related comments.
6901 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
6903 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
6904 wrapper that is not needed because the wrapped code is a no-op (zero
6905 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
6906 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
6908 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
6910 * alloc.c (mark_buffer): Simplify. Remove prototype.
6911 (mark_object): Add comment. Reorganize marking of vector-like
6912 objects. Use CHECK_LIVE for all vector-like objects except buffers
6913 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
6914 Avoid redundant calls to mark_vectorlike for bool vectors.
6916 2012-06-30 Glenn Morris <rgm@gnu.org>
6918 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
6920 * epaths.in (PATH_SITELOADSEARCH): New.
6921 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
6922 This is rather than relying on --enable-locallisppath elements
6923 having "site-lisp" in their names. (Bug#10208#25, 11658)
6925 2012-06-30 Eli Zaretskii <eliz@gnu.org>
6927 * w32proc.c (sys_select): Accept and ignore one more argument.
6929 * w32.c (emacs_gnutls_pull): Call select with one more argument.
6931 * sysselect.h [DOS_NT]: Don't include sys/select.h.
6932 (pselect) [!MS_DOS]: Redirect to sys_select.
6934 * sysdep.c: Don't include dos.h and dosfns.h.
6936 * process.c (sys_select):
6937 * msdos.c (sys_select): Accept one more argument and ignore it.
6939 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
6940 adapt data types and code to that.
6943 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
6944 which clashes with the gnulib function of the same name.
6946 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
6948 * font.c (font_style_to_value, font_style_symbolic)
6949 (font_prop_validate_style): Add type checks for values in
6952 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
6954 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
6957 2012-06-29 Eli Zaretskii <eliz@gnu.org>
6959 * xdisp.c (try_window_id): Undo last change.
6961 * w32.c (getwd): Adjust commentary about startup_dir.
6962 (init_environment): Always call sys_access, even in non-MSVC
6963 builds. Don't chdir to the directory of the Emacs executable.
6964 This undoes code from 1997 which was justified by the need to
6965 "avoid conflicts when removing and renaming directories". But its
6966 downside was that every relative file name was being interpreted
6967 relative to the directory of the Emacs executable, which can never
6968 be TRT. In particular, it broke sys_access when called with
6969 relative file names.
6970 (sys_access): Map GetLastError to errno.
6972 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
6974 * window.h (struct window): Change type of 'fringes_outside_margins'

6978 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
6981 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>

6984 Add QUIT to make the loop interruptible.
6986 2012-06-29 Glenn Morris <rgm@gnu.org>
6988 * charset.c (init_charset): Make lack of etc/charsets fatal.
6990 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

6994 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

6997 undefined. Convert from xassert to eassert.

7005 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
7007 Avoid integer overflow on scroll-left and scroll-right.
7008 * window.c (HSCROLL_MAX): New macro.
7009 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
7010 overflow when requested scroll falls outside ptrdiff_t range.

7014 * window.h (struct window): Change type of 'hscroll',
7015 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
7016 'last_modified' and 'last_overlay_modified' to EMACS_INT.
7017 Adjust users accordingly.
7018 * xdisp.c (try_cursor_movement): Replace type check with eassert.
7019 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
7020 from EMACS_INT to ptrdiff_t.
7021 (make_window): Omit redundant initialization.

7096 * alloc.c (allocate_string): Omit intervals initialization.
7097 * alloc.c (make_uninit_multibyte_string): Initialize intervals
7098 as in make_pure_string and make_pure_c_string.

7154 * alloc.c: Remove build_string.
7155 * lisp.h: Define build_string as static inline. This provides
7156 a better opportunity to optimize away calls to strlen when the
7157 function is called with compile-time constant argument.
7158 * image.c (imagemagick_error): Convert to build_string.
7159 * w32proc.c (sys_spawnve): Likewise.

7162 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
7164 Use sprintf return value instead of invoking strlen on result.
7165 In the old days this wasn't portable, since some sprintf
7166 implementations returned char *. But they died out years ago and
7167 Emacs already assumes sprintf returns int.
7168 Similarly for float_to_string.
7169 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

7176 * xfns.c (syms_of_xfns):
7177 Use sprintf or float_to_string result to avoid need to call strlen.
7178 * data.c (Fnumber_to_string):
7179 Use make_unibyte_string, since the string must be ASCII.
7180 * lisp.h, print.c (float_to_string): Now returns int length.
7181 * term.c (produce_glyphless_glyph):
7182 Use sprintf result rather than recomputing it.
7184 Clean out last vestiges of the old HAVE_CONFIG_H stuff.

7217 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

7222 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
7223 instead of truncating it to 63 (admittedly a generous limit).

7353 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
7355 Support higher-resolution time stamps (Bug#9000).
7356 The time stamps are only nanosecond-resolution at the C level,
7357 since that's the best that any real-world system supports now.
7358 But they are picosecond-resolution at the Lisp level, as that's
7359 easy, and leaves room for future OS improvements.
7361 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
7364 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
7365 Don't get current time unless it's needed.
7367 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
7368 now provides it if it's absent.
7369 (start_atimer): Port to higher-res time stamps.
7370 Check for time stamp overflow. Don't get current time more
7371 often than is needed.
7373 * buffer.h (struct buffer): Buffer modtime now has high resolution.
7374 Include systime.h, not time.h.
7375 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
7377 * dired.c: Include stat-time.h.
7378 (Ffile-attributes): File times now have higher resolution.

7381 (struct image): Timestamp now has higher resolution.
7383 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
7384 has at least microseconds now. All uses removed.
7385 (update_frame, update_single_window, update_window, update_frame_1)
7386 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
7387 (duration_to_sec_usec): Remove; no longer needed.

7395 (decode_time_components, lisp_seconds_argument): New functions.
7396 (make_time): Now static.
7397 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
7398 Report an error if the time is invalid, rather than having the caller
7401 * fileio.c: Include <stat-time.h>
7402 (Fcopy_file): Copy higher-resolution time stamps.
7403 Prefer to set the time stamp via a file descriptor if that works.

7405 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
7406 (Fvisited_file_modtime, Fset_visited_file_modtime):
7407 Support higher-resolution time stamps.
7409 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
7411 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
7413 * image.c (prepare_image_for_display, clear_image_cache)
7414 (lookup_image): Port to higer-resolution time stamps.
7416 * keyboard.c (start_polling, bind_polling_period):
7417 Check for time stamp overflow.
7418 (read_char, kbd_buffer_get_event, timer_start_idle)
7419 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
7420 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
7421 Port to higher-resolution time stamps. Do not assume time_t is signed.
7422 (decode_timer): New function. Timers are now vectors of length 9,
7423 not 8, to accommodate the picosecond component.
7424 (timer_check_2): Use it.
7426 * nsterm.m (select_timeout, timeval_subtract): Remove.
7427 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
7428 as they're a bit more accurate and handle overflow better.
7429 (ns_select): Change prototype to be compatible with pselect.
7430 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
7431 * nsterm.h (ns_select): Adjust prototype.
7433 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
7434 us-resolution time stamps.
7435 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
7437 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
7439 * lisp.h (time_overflow): New decl.
7440 (wait_reading_process_output): First arg is now intmax_t, not int,
7441 to accommodate larger waits.
7443 * process.h (struct Lisp_Process.read_output_delay):
7444 Now counts nanoseconds, not microseconds.
7445 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
7447 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
7448 (wait_reading_process_output):
7449 Port to ns-resolution time stamps.
7450 (Faccept_process_output, wait_reading_process_output):
7451 Check for time stamp overflow. Do not assume time_t is signed.
7452 (select_wrapper): Remove; we now use pselect.
7453 (Fprocess_attributes): Now generates ns-resolution time stamps.
7455 * sysdep.c: Include utimens.h. Don't include utime.h
7456 or worry about struct utimbuf; gnulib does that for us now.
7457 (gettimeofday): Remove; gnulib provides a substitute.
7458 (make_timeval): New function.
7459 (set_file_times): Now sets ns-resolution time stamps.
7460 New arg FD; all uses changed.
7461 (time_from_jiffies, ltime_from_jiffies, get_up_time)
7462 (system_process_attributes):
7463 Now returns ns-resolution time stamp. All uses changed.
7464 Check for time stamp overflow.
7466 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
7467 provides a substitute now.
7469 * systime.h: Include timespec.h rather than sys/time.h and time.h,
7470 since it guarantees struct timespec.
7471 (EMACS_TIME): Now struct timespec, so that we can support
7472 ns-resolution time stamps.
7473 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
7474 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
7475 (EMACS_USECS): Remove.
7476 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
7477 so multiply the arg by 1000 before storing it.
7478 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
7480 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
7481 Port to ns-resolution time stamps.
7482 (EMACS_TIME_NEG_P): Remove; replaced by....
7483 (EMACS_TIME_SIGN): New macro.
7484 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
7485 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
7486 (set_file_times, make_time, lisp_time_argument): Adjust signature.
7487 (make_timeval, make_lisp_time, decode_time_components): New decls.
7488 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
7489 that it mishandled time_t overflow. You can't compare by subtracting!
7490 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
7491 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
7493 * term.c: Include <sys/time.h>.
7494 (timeval_to_Time): New function, for proper overflow wraparound.

7499 (Fprimitive_undo): Use them when restoring time stamps.
7501 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
7502 (w32_get_internal_run_time):
7503 Port to higher-resolution Emacs time stamps.
7504 (ltime): Now accepts single 64-bit integer, as that's more convenient
7507 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
7509 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
7510 for compatibility with pselect. Support ns-resolution time stamps.
7512 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
7514 * xselect.c (wait_for_property_change, x_get_foreign_selection):
7515 Check for time stamp overflow, and support ns-resolution time stamps.
7517 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
7518 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
7519 (timeval_subtract): Remove; no longer needed.
7520 (XTflash, XTring_bell, x_wait_for_event):
7521 Port to ns-resolution time stamps. Don't assume time_t is signed.
7523 2012-06-22 Chong Yidong <cyd@gnu.org>

7527 2012-06-22 Eli Zaretskii <eliz@gnu.org>
7529 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
7530 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
7531 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
7532 staticidx goes up to 1597 out of 1600 = 0x640.)
7534 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
7536 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
7537 Otherwise, the umask might be mistakenly 0 while handling input signals.

7559 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
7561 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,

7572 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
7573 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

7582 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
7583 gets killed during executing of this function (Bug#11665).
7584 Try to always return Qt when the buffer has been actually killed.
7585 (Vkill_buffer_query_functions): In doc-string say that functions
7586 run by this hook should not change the current buffer.
7588 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

7608 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
7610 * lisp.h (eassert): Assume C89 or later.
7611 This removes the need for CHECK.
7612 (CHECK): Remove. Its comments about always evaluating its
7613 argument were confusing, as 'eassert' typically does not evaluate
7616 * coding.c (produce_chars): Use ptrdiff_t, not int.
7618 * xterm.c (x_draw_underwave): Check for integer overflow.
7619 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

7753 * makefile.w32-in ($(BLD)/data.$(O)): Update dependencies.
7755 2012-06-13 Glenn Morris <rgm@gnu.org>

7771 * frame.c (delete_frame): Remove outdated comment.
7772 * w32fns.c (Fw32_register_hot_key): Use XLI instead of checking
7773 USE_LISP_UNION_TYPE.

7803 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
7804 code works fine either way, and efficiency is not a concern here,
7805 as the union type is for debugging, not for production.
7806 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
7807 Use an inline function on all platforms when using the union type,
7808 since this is simpler and 'static inline' can be used portably
7810 (LISP_INITIALLY_ZERO): New macro.
7811 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
7812 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

7881 dbus_type_is_basic if available.
7882 (xd_extract_signed, xd_extract_unsigned): Rename from
7883 extract_signed and extract_unsigned, respectively. Adapt callers.
7885 2012-06-09 Chong Yidong <cyd@gnu.org>

7915 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
7917 2012-06-08 Eli Zaretskii <eliz@gnu.org>
7919 * alloc.c (allocate_vectorlike): Fix last change.

7923 Block-based vector allocation of small vectors.
7924 * lisp.h (struct vectorlike_header): New field `nbytes',
7925 adjust comment accordingly.

7950 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
7952 * doprnt.c (doprnt): Truncate multibyte char correctly.
7953 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
7954 would mishandle a string argument "Xc" if X was a multibyte
7955 character of length 2: it would truncate after X's first byte
7956 rather than including all of X.
7958 2012-06-06 Chong Yidong <cyd@gnu.org>
7960 * buffer.c (word_wrap): Doc fix.

8009 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
8010 Convert pctcpu and pctmem to Lisp float properly.
8011 Let the compiler fold better, as 100.0/0x8000 is exact.
8013 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
8015 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
8018 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
8020 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
8022 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>

8025 bitfields where appropriate, remove unused fields.
8026 * window.h (struct window): Remove unused 'last_mark_x' and
8027 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
8028 change its type from Lisp_Object to bitfield.
8029 Change type of 'force_start', 'optional_new_start',
8030 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
8031 fields from Lisp_Object to bitfield. Adjust users accordingly.
8033 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
8035 Pacify gcc -Wdouble-precision when using Xaw.

8039 and 'double' in a couple of places.
8041 2012-05-31 Eli Zaretskii <eliz@gnu.org>
8043 * xdisp.c (handle_stop): Detect whether we have overlay strings
8044 loaded by testing it->current.overlay_string_index to be
8045 non-negative, instead of checking whether n_overlay_strings is
8046 positive. (Bug#11587)
8048 2012-05-31 Chong Yidong <cyd@gnu.org>
8050 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

8056 * search.c (search_buffer): Remove calls to
8057 r_alloc_inhibit_buffer_relocation, as it is now called by
8058 maybe_unify_char, which was the cause of relocation of buffer text
8061 2012-05-31 Eli Zaretskii <eliz@gnu.org>
8063 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
8064 for the duration of call to load_charset, to avoid problems with
8065 callers of maybe_unify_char that access buffer text through C
8068 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
8069 decrement the inhibition flag, instead of just setting or
8072 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
8074 Remove obsolete '#define static' cruft.
8075 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
8076 This #undef was "temporary" in 2000; it is no longer needed
8077 now that '#define static' has gone away.
8078 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
8079 (gray_bitmap_bits): Remove; no longer needed.
8080 All uses replaced with definiens.

8092 (safe_bcopy): Remove decl; no longer has that name.
8093 (main): Coalesce #if into single bit of code, for simplicity.

8124 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
8125 Bug#9642, but explicitly check that the buffer the overlay would
8126 be moved to is live and rearrange lines to make sure that errors
8127 will not put the overlay in an inconsistent state.
8128 (Fdelete_overlay): Cosmetics.
8130 2012-05-28 Eli Zaretskii <eliz@gnu.org>
8132 * w32term.c (my_bring_window_to_top): New function.

8168 the others were already declared.
8170 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
8171 before checking whether it's out of range. Put the check inside
8173 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.

8183 defined on ralloc.c.
8185 * buffer.c [REL_ALLOC]: Remove prototypes of

8187 they are now on lisp.h.
8189 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
8191 * search.c (search_buffer): Use it to inhibit relocation of buffer
8192 text while re_search_2 is doing its job, because re_search_2 is
8193 passed C pointers to buffer text. (Bug#11519)
8195 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
8198 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator

8208 Fix coding-related core dumps with gcc -ftrapv.
8209 The code was computing A - B, where A and B are pointers, and B is
8210 random garbage. This can lead to core dumps on platforms that
8211 have special pointer registers, and it also leads to core dumps on
8212 x86-64 when compiled with gcc -ftrapv. The fix is to compute
8213 A - B only when B is initialized properly.
8214 * coding.c (coding_set_source, coding_set_destination): Return void.
8215 (coding_change_source, coding_change_destinations): New functions,
8216 with the old behaviors of coding_set_source and coding_set_destination.

8234 * w32inevt.c: Include termchar.h and window.h.
8235 (do_mouse_event): Support mouse-autoselect-window. When the mouse
8236 moves, call note_mouse_highlight. If help_echo changed, call
8237 gen_help_event to produce help-echo message in the echo area.
8238 Call clear_mouse_face if mouse_face_hidden is set in the mouse
8241 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>

8244 with GCC 4.7.0 on x86-64.
8246 2012-05-26 Eli Zaretskii <eliz@gnu.org>
8248 * bidi.c (bidi_mirror_char): Revert last change: an int is
8249 definitely wide enough here.
8251 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>

8265 Use int, not EMACS_INT, where int is wide enough.

8285 (Foverlay_recenter, last_overlay_modification_hooks_used)
8286 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
8287 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8288 (validate_region): Omit unnecessary test for b <= e,
8289 since that's guaranteed by the previous test.
8290 (adjust_overlays_for_delete): Avoid pos + length overflow.
8291 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
8292 (report_overlay_modification):

8294 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):

8296 after the EMACS_INT -> ptrdiff_t change.

8298 * buffer.h: Adjust decls to match defn changes elsewhere.

8303 not int, to avoid needless 32-bit limit on 64-bit hosts.
8304 (exec_byte_code): Use tighter memory-full test, one that checks
8305 for alloca overflow. Don't compute the address of the object just
8306 before an array, as that's not portable. Use EMACS_INT, not
8307 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
8308 * callint.c (Fcall_interactively):
8309 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

8321 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8322 (casify_object): Avoid integer overflow when overallocating buffer.
8323 * casetab.c (set_identity, shuffle): Prefer int to unsigned when

8325 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
8326 * category.h (CATEGORYP): Don't assume arg is nonnegative.
8327 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the

8330 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8331 For CCL_MapSingle, check that content and value are in int range.
8332 (ccl_driver, Fregister_code_conversion_map):
8333 Check that Vcode_version_map_vector is a vector.
8334 (resolve_symbol_ccl_program): Check that vector header is in range.
8335 Always copy the vector, so that we can check its contents reliably
8336 now rather than having to recheck each instruction as it's being
8337 executed. Check that vector words fit in 'int'.
8338 (ccl_get_compiled_code, Fregister_ccl_program)
8339 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
8340 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

8342 contents are in range.
8343 (Fccl_execute_on_string): Check that status is in range.
8344 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
8345 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
8346 Accept and return EMACS_INT, not int, because callers can pass values

8353 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

8355 avoid mishandling large integers.

8366 Don't rely on undefined behavior with signed left shift overflow.
8367 Don't assume unsigned int fits into fixnum, or that fixnum fits
8368 into unsigned int. Don't require max_code to be a valid fixnum;
8369 that's not true for gb10830 4-byte on a 32-bit host. Allow
8370 invalid_code to be a cons, for the same reason. Require code_offset
8371 to be a character. Avoid int overflow if max_char is close
8373 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
8374 this is intended anyway and avoids some undefined behavior.
8375 (load_charset_map): Pass unsigned, not int, as 2nd arg of
8376 INDEX_TO_CODE_POINT, as that's what it expects.
8377 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
8378 * charset.h (DECODE_CHAR): Return int, not unsigned;
8379 this is what was intended anyway, and it avoids undefined behavior.
8380 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
8381 integer-overflow issues.
8382 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
8383 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
8384 where the argument is EMACS_INT, and this behavior is not intended.
8385 * chartab.c (Fmake_char_table, Fset_char_table_range)
8386 (uniprop_get_decoder, uniprop_get_encoder):
8387 Don't assume fixnum fits in int.
8388 * cmds.c (move_point): New function, that does the gist of
8389 Fforward_char and Fbackward_char, but does so while checking
8390 for integer overflow more accurately.
8391 (Fforward_char, Fbackward_char): Use it.
8392 (Fforward_line, Fend_of_line, internal_self_insert)
8393 (internal_self_insert):
8394 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

9094 what used to be in config.h, but not useful in #if.
9095 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
9096 define them any more.
9097 (VAL_MAX): New macro.

9104 * s/ms-w32.h (DATA_START):
9105 Move here from removed file m/intel386.h.
9106 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
9107 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
9109 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>

9175 2012-05-14 Glenn Morris <rgm@gnu.org>
9177 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
9178 Put "libexec" before "bin", for the sake of init_callproc_1.
9180 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
9182 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.

9185 (report_error, report_error_1, make_hdr, copy_sym)
9186 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
9187 Make arguments const char *, not char *, to avoid violations of C
9188 standard and to fix some AIX warnings reported by Gilles Pion.
9190 2012-05-14 Eli Zaretskii <eliz@gnu.org>
9192 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
9193 already have overlays loaded.
9194 (handle_single_display_spec): Before returning without displaying
9195 fringe bitmap, synchronize the bidi iterator with the main display
9196 iterator, by calling iterate_out_of_display_property.
9197 (iterate_out_of_display_property): Detect buffer iteration by
9198 testing that it->string is a Lisp string.
9199 (get_next_display_element): When the current object is exhausted,
9200 and there's something on it->stack, call set_iterator_to_next to
9201 proceed with what's on the stack, instead of returning zero.
9202 (set_iterator_to_next): If called at the end of a Lisp string,
9203 proceed to consider_string_end without incrementing string
9204 position. Don't increment display vector index past the end of
9205 the display vector. (Bug#11417)
9206 (pos_visible_p): Don't report a position visible when move_it_to
9207 stopped at the last line of window, which happens to be scanned
9208 backwards by the bidi iteration. (Bug#11464)
9210 2012-05-14 Eli Zaretskii <eliz@gnu.org>
9212 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
9213 and right-margin display specs even if the spec is invalid or we
9214 are on a TTY, and thus unable to display on the fringes.
9215 That's because the text with the property will not be displayed anyway,
9216 so we need to signal to the caller that this is a "replacing"
9217 display spec. This fixes display when the spec is invalid or we
9220 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
9222 * unexaix.c (make_hdr): Fix typo in prototype.
9223 This bug broke the build on AIX. Problem reported by Gilles Pion.
9225 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
9227 * keyboard.c (kbd_buffer_get_event): Read special events also in
9228 batch mode. (Bug#11415)

9238 2012-05-12 Glenn Morris <rgm@gnu.org>

9241 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
9243 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>

9253 Update dependencies.
9255 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
9257 * xgselect.c (xg_select): Put maxfds+1 into a var.
9258 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
9260 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
9262 2012-05-10 Dave Abrahams <dave@boostpro.com>
9264 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
9265 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
9267 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
9269 * dbusbind.c (xd_registered_buses): New internal Lisp object.
9270 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
9271 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
9272 Initialize xd_registered_buses.
9274 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
9276 Untag more efficiently if USE_LSB_TAG.
9277 This is based on a proposal by YAMAMOTO Mitsuharu in
9278 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
9279 For an admittedly artificial (nth 8000 longlist) benchmark on
9280 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
9281 Emacs's overall text size by 1%.
9282 * lisp.h (XUNTAG): New macro.
9283 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
9284 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
9285 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
9286 * eval.c (Fautoload):
9287 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
9288 * frame.h (XFRAME): Use XUNTAG.
9290 Port recent dbusbind.c changes to 32-bit --with-wide-int.
9291 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
9292 Remove unportable assumptions about print widths of types like
9294 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
9295 intptr_t when converting between pointer and integer, to avoid GCC
9296 warnings about wrong width.
9298 2012-05-09 Eli Zaretskii <eliz@gnu.org>
9300 * w32proc.c (new_child): Force Windows to reserve only 64KB of
9301 stack for each reader_thread, instead of defaulting to 8MB
9302 determined by the linker. This avoids failures in creating
9303 subprocesses on Windows 7, see the discussion in this thread:
9304 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
9306 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
9308 Fix up display of the *Minibuf-0* buffer in the mini window.
9309 * keyboard.c (read_char): Don't clear the echo area if there's no
9311 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
9312 contents of *Minibuf-0*) if there's no message displayed in its stead.
9314 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
9316 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
9319 2012-05-06 Chong Yidong <cyd@gnu.org>
9321 * lisp.mk (lisp): Update.
9323 2012-05-05 Jim Meyering <meyering@redhat.com>
9325 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
9327 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
9329 * data.c (PUT_ERROR): New macro.
9330 (syms_of_data): Use it. Add new error type `user-error'.
9331 * undo.c (user_error): New function.
9332 (Fprimitive_undo): Use it.
9333 * print.c (print_error_message): Adjust print style for `user-error'.
9334 * keyboard.c (user_error): New function.
9335 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
9337 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
9339 Do not limit current-time-string to years 1000..9999.
9340 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
9341 (Fcurrent_time_string): Support any year that is supported by the
9342 underlying localtime representation. Don't use asctime, as it
9343 has undefined behavior for years outside the range -999..9999.
9345 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
9347 Fix race conditions involving setenv, gmtime, localtime, asctime.
9348 Without this fix, interrupts could mess up code that uses these
9349 nonreentrant functions, since setting TZ invalidates existing
9350 tm_zone or tzname values, and since most of these functions return
9351 pointers to static storage.
9352 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
9353 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
9354 Grow the critical sections to include not just invoking
9355 localtime/gmtime, but also accessing these functions' results
9356 including their tm_zone values if any, and any related TZ setting.
9357 (format_time_string): Last arg is now struct tm *, not struct tm **,
9358 so that the struct tm is saved in the critical section.
9359 All callers changed. Simplify allocation of initial buffer, partly
9360 motivated by the fact that memory allocation needs to be outside
9361 the critical section.
9363 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
9365 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
9366 with RESET_INTERVAL.
9368 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
9369 Remove duplicated buffer name initialization.
9371 2012-05-02 Jim Meyering <jim@meyering.net>
9373 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
9375 * xfns.c (x_window): Use xstrdup (Bug#11375).
9377 2012-05-02 Eli Zaretskii <eliz@gnu.org>
9379 * xdisp.c (pos_visible_p): If already at a newline from the
9380 display string before the 'while' loop, don't walk back the glyphs
9381 from it3.glyph_row. Solves assertion violation when the display
9382 string begins with a newline (egg.el). (Bug#11367)
9384 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
9386 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
9389 2012-05-01 Glenn Morris <rgm@gnu.org>
9391 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
9392 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
9393 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
9394 All were removed before 23.1.
9396 * dispnew.c: Remove HAVE_LIBNCURSES test;
9397 it is always true on relevant platforms.
9399 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
9400 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
9402 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
9404 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
9406 * .gdbinit (xpr): Remove checks for no longer existing misc types.
9407 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
9410 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
9412 Do not avoid creating empty evaporating overlays (Bug#9642).
9413 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
9414 That is, do not delete an evaporating overlay if it becomes
9415 empty after its bounds are adjusted to fit within its buffer.
9416 This fix caused other problems, and I'm reverting it until we get
9417 to the bottom of them.
9419 2012-04-27 Chong Yidong <cyd@gnu.org>
9421 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
9423 2012-04-27 Eli Zaretskii <eliz@gnu.org>
9425 * xdisp.c (pos_visible_p): If the window start position is beyond
9426 ZV, start the display from buffer beginning. Prevents assertion
9427 violation in init_iterator when the minibuffer window is scrolled
9430 * window.c (window_scroll_pixel_based): Likewise.
9432 2012-04-27 Chong Yidong <cyd@gnu.org>
9434 * keymap.c (where_is_internal): Doc fix (Bug#10872).
9436 2012-04-27 Glenn Morris <rgm@gnu.org>
9438 * fileio.c (Fcopy_file, Fset_file_selinux_context):
9439 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
9441 2012-04-27 Eli Zaretskii <eliz@gnu.org>
9443 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
9444 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
9446 2012-04-26 Eli Zaretskii <eliz@gnu.org>
9448 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
9449 display element, check also the underlying string or buffer
9450 character. (Bug#11341)
9452 * w32menu.c: Include w32heap.h.
9453 (add_menu_item): If the call to AppendMenuW (via
9454 unicode_append_menu) fails, disable Unicode menus only if we are
9455 running on Windows 9X/Me.
9457 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
9459 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
9460 (xgetint): Add missing shift for LSB tags.
9462 2012-04-24 Martin Rudalics <rudalics@gmx.at>
9464 * keyboard.c (read_char): Don't wipe echo area for select window
9465 events: These might get delayed via `mouse-autoselect-window'
9468 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
9470 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
9471 manipulation of :loaded-from data.
9473 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
9475 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
9476 now a cons (bug#11311).
9478 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
9480 Do not create empty overlays with the evaporate property (Bug#9642).
9481 * buffer.c (Fmove_overlay): Delete an evaporating overlay
9482 if it becomes empty after its bounds are adjusted to fit within
9483 its buffer. Without this fix, in a nonempty buffer (let ((o
9484 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
9485 yields an empty overlay that has the evaporate property, which is
9486 not supposed to happen.
9488 Fix minor GTK3 problems found by static checking.
9489 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
9490 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
9491 (struct _EmacsFixedClass, emacs_fixed_get_type):

9501 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
9503 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
9504 Problem reported by Juanma Barranquero for Windows -Wunused-function.
9506 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
9508 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
9509 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
9510 (__malloc_size_t, __malloc_ptrdiff_t):
9511 Remove. All uses removed, replaced by the definiens if needed,
9512 since we can assume C89 or better now.
9513 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

9522 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
9523 Define using prototypes, not old style.
9524 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
9525 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
9526 (align): Don't assume that signed integer overflow wraps around.
9527 Omit unused local var.
9528 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
9529 (_free_internal_nolock, memalign, mallochook, reallochook):

9535 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
9537 2012-04-22 Michael Albinus <michael.albinus@gmx.de>

9588 * alloc.c: Handle unusual debugging option combinations.
9589 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
9590 since the two debugging options are incompatible.
9591 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
9593 (mem_init, mem_insert, mem_insert_fixup):
9594 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

9603 * sysdep.c [__FreeBSD__]: Minor cleanups.
9604 (list_system_processes, system_process_attributes) [__FreeBSD__]:
9605 Use Emacs indenting style more consistently. Avoid some casts.
9606 Use 'double' consistently rather than mixing 'float' and 'double'.
9608 2012-04-21 Eduard Wiebe <usenet@pusto.de>
9610 * sysdep.c (list_system_processes, system_process_attributes):
9611 Add implementation for FreeBSD (Bug#5243).

9617 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
9619 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
9620 It is never used otherwise.
9622 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
9624 * print.c (print_preprocess): Only check print_depth if print-circle
9626 (print_object): Check for cycles even when print-circle is nil and
9627 print-gensym is t, but only check print_depth if print-circle is nil.
9629 2012-04-20 Chong Yidong <cyd@gnu.org>
9631 * process.c (wait_reading_process_output): If EIO occurs on a pty,
9632 set the status to "failed" and ensure that sentinel is run.
9634 2012-04-20 Glenn Morris <rgm@gnu.org>
9636 * process.c (Fset_process_inherit_coding_system_flag)

9645 row, return zero immediately.
9646 (try_cursor_movement): If inside continuation line, don't back up
9647 farther than the first row after the header line, if any.
9648 Don't consider the header-line row as "partially visible", even if
9649 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
9651 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

9687 New extern decls, to avoid calling undeclared functions.
9688 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
9689 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
9690 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
9691 (NEED_MEM_INSERT): New macro.
9692 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
9693 Remove one incorrect comment and fix another.

9698 (r_alloc_size_in_use, r_alloc_freeze, r_alloc_thaw): Remove; unused.
9699 (r_alloc_sbrk): Now static.
9701 Improve ralloc.c interface checking.
9702 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
9703 * buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)
9704 (r_alloc_free) [REL_ALLOC]: Move decls from here ...
9705 * lisp.h (r_alloc, r_alloc_free, r_re_alloc, r_alloc_reset_variable)
9706 [REL_ALLOC]: ... to here, to check interface.
9707 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
9708 Remove decls. This fixes an "It stinks!".
9710 * alloc.c (which_symbols): Fix alignment issue / type clash.
9712 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
9714 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
9715 (struct Lisp_Misc_Any): Likewise.
9716 (struct Lisp_Free): Likewise.

9723 (Fmake_symbol, allocate_misc, gc_sweep): Adjust.
9725 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
9727 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
9728 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
9729 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
9730 * s/netbsd.h, s/sol2-6.h:
9731 Remove definition of GC_MARK_STACK, since the default now works.
9732 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
9733 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
9734 no longer the default.
9735 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
9737 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
9739 * lread.c (lisp_file_lexically_bound_p):

9760 2012-04-11 Daniel Colascione <dancol@dancol.org>
9762 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
9763 against is gone. It's better to use vfork now so that when Cygwin
9764 gains a new, working vfork, we use it automatically (bug#10398).
9766 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

9778 2012-04-10 Jason S. Cornez <jcornez@ravenpack.com> (tiny change)
9780 * keyboard.c: Override inhibit-quit after the third C-g (bug#6585).
9781 (force_quit_count): New var.
9782 (handle_interrupt): Use it.
9784 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
9786 * w32.c (w32_delayed_load): Record the full path of the library
9787 being loaded (bug#10424).
9789 2012-04-09 Glenn Morris <rgm@gnu.org>
9791 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
9792 not just in the obarray, before snarfing them. (Bug#11036)
9794 * Makefile.in ($(leimdir)/leim-list.el):
9795 Pass EMACS rather than BUILT_EMACS.
9797 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
9799 * process.c (make_process):
9800 * process.h: Add integer `gnutls_handshakes_tried' member to
9803 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
9804 Add convenience `GNUTLS_LOG2i' macro.
9806 * gnutls.c (gnutls_log_function2i): Convenience log function.
9807 (emacs_gnutls_read): Use new log functions,
9808 `gnutls_handshakes_tried' process member, and
9809 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
9810 attempts per process (connection).
9812 2012-04-09 Chong Yidong <cyd@gnu.org>
9814 * eval.c (Fuser_variable_p, user_variable_p_eh)

9819 * minibuf.c (Fread_variable): Callers changed.
9821 2012-04-09 Eli Zaretskii <eliz@gnu.org>
9823 * xdisp.c (set_cursor_from_row): If the display string appears in
9824 the buffer at position that is closer to point than the position
9825 after the display string, display the cursor on the first glyph of
9826 the display string. Fixes cursor display when a 'display' text
9827 property immediately follows invisible text. (Bug#11094)
9829 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
9831 composite.c: use 'double' consistently
9832 * composite.c (get_composition_id): Use 'double' consistently
9833 instead of converting 'float' to 'double' and vice versa; this is
9834 easier to understand and avoids a GCC warning.
9836 2012-04-09 Glenn Morris <rgm@gnu.org>
9838 * Makefile.in: Generate leim-list with bootstrap-emacs, in
9839 preparation for dumping it with emacs. (Bug#4789)
9840 (leimdir): New variable.
9841 ($(leimdir)/leim-list.el): New rule.
9842 (emacs$(EXEEXT)): Depend on leim-list.el.

9861 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
9862 (mark_memory): Mark Lisp_Objects only if pointers might hide in
9863 objects, as mark_maybe_pointer will catch them otherwise.
9864 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
9865 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
9867 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
9869 Fix typo that broke non-Windows builds.
9870 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
9872 2012-04-07 Eli Zaretskii <eliz@gnu.org>
9874 Support building on MS-Windows with libxml2.
9876 * makefile.w32-in (OBJ2): Add xml.$(O).
9877 (GLOBAL_SOURCES): Add xml.c.
9878 ($(BLD)/xml.$(O)): New dependency list.
9880 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
9881 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
9882 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
9883 [!WINDOWSNT]: New macros.
9884 (init_libxml2_functions, libxml2_loaded_p): New functions.
9885 (parse_region): Call fn_xmlCheckVersion instead of using the macro
9886 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
9887 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
9888 Calls xmlCleanupParser only if libxml2 was loaded (or statically
9890 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
9891 Call init_libxml2_functions before calling libxml2 functions.
9892 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
9894 * emacs.c: Don't include libxml/parser.h.
9895 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
9896 xmlCleanupParser directly.
9898 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
9900 2012-04-07 Eli Zaretskii <eliz@gnu.org>
9902 * indent.c (Fvertical_motion): If there is a display string at
9903 point, use it.vpos to compute how many lines to backtrack after
9904 move_it_to point. (Bug#11133)
9906 2012-04-06 Eli Zaretskii <eliz@gnu.org>
9908 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
9909 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
9910 about subtle differences between FETCH_CHAR* and STRING_CHAR*
9911 macros related to unification of CJK characters. For the details,
9912 see the discussion following the message here:
9913 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
9915 2012-04-04 Chong Yidong <cyd@gnu.org>
9917 * keyboard.c (Vdelayed_warnings_list): Doc fix.
9919 2012-04-01 Eli Zaretskii <eliz@gnu.org>
9921 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
9922 instead of alloca. (Bug#11138)
9924 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
9926 * w32menu.c (is_simple_dialog): Properly check lisp types.
9929 2012-03-31 Eli Zaretskii <eliz@gnu.org>
9931 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
9932 position we get to after a call to move_it_to fails the
9933 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
9934 only if we wind up in a string from display property. (Bug#11063)
9936 * window.c (Fdelete_other_windows_internal): Invalidate the row
9937 and column information about mouse highlight, so that redisplay
9938 restores it after reallocating the glyph matrices. (Bug#7464)
9940 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
9941 string comes from a `display' text property, use the buffer
9942 position of that property as if we actually saw that position in
9944 (move_it_by_lines): Remove the assertion that
9945 "it->current_x == 0 && it->hpos == 0" which can be legitimately
9946 violated when there's a before-string at the beginning of a line.
9949 2012-03-30 Eli Zaretskii <eliz@gnu.org>
9951 * xdisp.c (append_space_for_newline): If the default face was
9952 remapped, use the remapped face for the appended newline.
9953 (extend_face_to_end_of_line): Use the remapped default face for
9954 extending the face to the end of the line.
9955 (display_line): Call extend_face_to_end_of_line when the default
9956 face was remapped. (Bug#11068)
9958 2012-03-29 Eli Zaretskii <eliz@gnu.org>
9960 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
9962 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
9964 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
9966 2012-03-27 Glenn Morris <rgm@gnu.org>
9968 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
9971 2012-03-26 Kenichi Handa <handa@m17n.org>
9973 * dispextern.h (struct glyph): Fix previous change. Change the
9974 bit length of glyphless.ch to 25 (Bug#11082).
9976 2012-03-26 Chong Yidong <cyd@gnu.org>
9978 * keyboard.c (Vselection_inhibit_update_commands): New variable.
9979 (command_loop_1): Use it; inhibit selection update for
9980 handle-select-window too (Bug#8996).
9982 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
9984 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
9986 2012-03-25 Kenichi Handa <handa@m17n.org>
9988 * dispextern.h (struct glyph): Change the bit length of
9989 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
9991 2012-03-24 Eli Zaretskii <eliz@gnu.org>
9993 * s/ms-w32.h (tzname): Include time.h before redirecting to
9994 _tzname. Fixes the MSVC build. (Bug#9960)
9996 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
9998 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
10001 * xterm.c (XTread_socket): Only modify handling_signal if
10002 !SYNC_INPUT. (Bug#11080)
10004 2012-03-23 Eli Zaretskii <eliz@gnu.org>
10006 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
10007 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
10008 when fetching a multibyte character consumes more bytes than
10009 CHAR_BYTES returns, due to unification of CJK characters in
10010 string_char. (Bug#11073)
10012 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
10014 * process.c (wait_reading_process_output): Handle pty disconnect
10015 by refraining from sending oneself a SIGCHLD (bug#10933).
10017 2012-03-22 Chong Yidong <cyd@gnu.org>
10019 * dispextern.h (struct it): New member string_from_prefix_prop_p.
10021 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
10022 Mark string as coming from a prefix property.
10023 (handle_face_prop): Use default face for prefix strings (Bug#4281).
10024 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
10026 2012-03-21 Chong Yidong <cyd@gnu.org>
10028 * xfaces.c (Vface_remapping_alist): Doc fix.
10030 2012-03-20 Eli Zaretskii <eliz@gnu.org>
10032 * w32proc.c (Fw32_set_console_codepage)
10033 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
10036 2012-03-20 Chong Yidong <cyd@gnu.org>
10038 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
10039 to reflect default non-nil value of redisplay-dont-pause.
10041 2012-03-19 Kenichi Handa <handa@m17n.org>
10043 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
10044 it fit in a valid range (Bug#11003).
10046 2012-03-18 Eli Zaretskii <eliz@gnu.org>
10048 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
10049 that is not from display property, accept the row as a "cursor
10050 row" if one of the string's character has a non-nil `cursor'
10051 property. Fixes cursor positioning when there are newlines in
10052 overlay strings, e.g. in icomplete.el. (Bug#11035)
10054 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
10056 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
10058 2012-03-12 Chong Yidong <cyd@gnu.org>
10060 * eval.c (inhibit_lisp_code): Rename from
10061 inhibit_window_configuration_change_hook; move from window.c.
10063 * xfns.c (unwind_create_frame_1, Fx_create_frame):
10064 * window.c (run_window_configuration_change_hook)
10065 (syms_of_window): Callers changed.
10067 2012-03-11 Chong Yidong <cyd@gnu.org>
10069 * keymap.c (Fkey_description): Doc fix (Bug#9700).
10071 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
10073 2012-03-10 Chong Yidong <cyd@gnu.org>
10075 * frame.c (other_visible_frames): Don't assume the selected frame
10076 is visible (Bug#10955).
10078 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
10080 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
10082 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
10084 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
10085 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
10088 2012-03-03 Glenn Morris <rgm@gnu.org>
10090 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
10092 2012-03-02 Eli Zaretskii <eliz@gnu.org>
10094 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
10095 position past the first glyph_row that ends at ZV. (Bug#10902)
10096 (redisplay_window, next_element_from_string): Fix typos in
10098 (redisplay_window): Pass to move_it_vertically the margin in
10099 pixels, not in screen lines.
10101 2012-03-02 Glenn Morris <rgm@gnu.org>
10103 * buffer.c (buffer-list-update-hook): Doc fix.
10105 2012-02-29 Eli Zaretskii <eliz@gnu.org>
10107 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
10108 push_it before setting up the iterator for the first overlay
10109 string, even if we have an empty string loaded.
10110 (next_overlay_string): If there's an empty string on the iterator
10111 stack, pop the stack. (Bug#10903)
10113 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
10115 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
10116 Suggested by Stefan Monnier in
10117 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
10118 * alloc.c (widen_to_Lisp_Object): New static function.
10119 (mark_memory): Also mark Lisp_Objects by fetching pointer words
10120 and widening them to Lisp_Objects. This would work even if
10121 USE_LSB_TAG is defined and wide integers are used, which might
10122 happen in a future version of Emacs.
10124 2012-02-25 Chong Yidong <cyd@gnu.org>
10126 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
10129 * xselect.c (Fx_selection_exists_p): Doc fix.
10130 (x_clipboard_manager_save_all): Print an informative message
10131 before saving to clipboard manager.
10133 2012-02-24 Chong Yidong <cyd@gnu.org>
10135 * keyboard.c (process_special_events): Handle all X selection
10136 requests in kbd_buffer, not just the next one (Bug#8869).
10138 2012-02-23 Chong Yidong <cyd@gnu.org>
10140 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
10141 call when setting menu-bar-lines and tool-bar-lines parameters.
10142 (unwind_create_frame_1): New helper function.
10144 * window.c (inhibit_window_configuration_change_hook): New var.
10145 (run_window_configuration_change_hook): Obey it.
10146 (syms_of_window): Initialize it.
10148 2012-02-22 Chong Yidong <cyd@gnu.org>
10150 * xterm.c (x_draw_image_relief): Add missing type check for
10151 Vtool_bar_button_margin (Bug#10743).
10153 2012-02-21 Chong Yidong <cyd@gnu.org>
10155 * fileio.c (Vfile_name_handler_alist): Doc fix.
10157 * buffer.c (Fget_file_buffer): Protect against invalid file
10158 handler return value.
10160 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
10162 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
10163 when computing $valmask.
10165 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
10166 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
10167 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
10168 It's useless in that case, and it can cause problems on hosts
10169 that allocate halves of EMACS_INT values separately.
10170 Reported by Dan Horák. Diagnosed by Andreas Schwab in
10171 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
10172 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
10173 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
10174 it avoids undefined behavior on hosts where shifting right by more
10175 than the word width has undefined behavior.
10177 2012-02-19 Chong Yidong <cyd@gnu.org>
10179 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
10180 (Funhandled_file_name_directory, Ffile_name_as_directory)
10181 (Fdirectory_file_name, Fexpand_file_name)
10182 (Fsubstitute_in_file_name): Protect against invalid file handler
10183 return values (Bug#10845).
10185 2012-02-18 Eli Zaretskii <eliz@gnu.org>
10187 * .gdbinit (pitx): Fix incorrect references to fields of the
10190 2012-02-17 Chong Yidong <cyd@gnu.org>
10192 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
10194 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
10196 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
10197 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
10199 2012-02-15 Chong Yidong <cyd@gnu.org>
10201 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
10202 marked as special. Also, starting docstrings with * is obsolete.
10204 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
10206 * gnutls.c (emacs_gnutls_write): Fix last change.

10215 * keymap.c (Fsingle_key_description): Handle char ranges.
10217 2012-02-12 Chong Yidong <cyd@gnu.org>
10219 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
10220 as that creates a dangerous corner case.
10222 * window.c (Fdelete_window_internal): Invalidate the mouse
10223 highlight (Bug#9904).
10225 2012-02-12 Glenn Morris <rgm@gnu.org>
10227 * xselect.c (Fx_own_selection_internal)
10228 (Fx_get_selection_internal, Fx_disown_selection_internal)
10229 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
10230 * nsselect.m (Fx_own_selection_internal)
10231 (Fx_disown_selection_internal, Fx_selection_exists_p)
10232 (Fx_selection_owner_p, Fx_get_selection_internal):
10233 Sync docs and argument specs with the xselect.c versions.
10235 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
10237 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
10239 2012-02-11 Eli Zaretskii <eliz@gnu.org>
10241 * w32select.c (Fx_selection_exists_p): Sync doc string and
10242 argument list with xselect.c. (Bug#10783)
10244 * w16select.c (Fx_selection_exists_p): Sync doc string and
10245 argument list with xselect.c. (Bug#10783)

10249 * fns.c (Fsecure_hash): Doc fix.
10251 2012-02-09 Kenichi Handa <handa@m17n.org>
10253 * coding.c (produce_chars): Fix updating of src_end (Bug#10701).
10255 2012-02-07 Chong Yidong <cyd@gnu.org>
10257 * buffer.c (Fbuffer_local_variables)

10792 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
10793 verifies glyph row's hash code--we have just reallocated the
10794 glyphs, so their contents can be complete garbage. (Bug#10164)

10840 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
10841 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in
10842 this macro definition.

10873 (start_display): Don't move to the next line if the display should
10874 start at a newline that is part of a display vector or an overlay

10958 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
10959 is set, removing the need for VIRT_ADDRESS_VARIES.
10960 (PURE_P): Use a more-efficient implementation that needs just one
10961 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
10962 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
10963 to 4 (xorl, subq, cmpq, setbe).
10964 * alloc.c (pure): Always extern now, since that's the

10967 consistency with the new puresize.h.
10968 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
10969 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

10975 (erase_phys_cursor, update_window_cursor, show_mouse_face)
10976 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
10977 behave as if the cursor position were at the window margin.
10979 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
10980 and the cursor position is out of bounds, behave as if the cursor
10981 position were at the window margin. (Bug#10075)
10983 2011-11-18 Chong Yidong <cyd@gnu.org>
10985 * window.c (Fwindow_combination_limit): Make first argument

11004 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
11006 * xdisp.c (row_hash): New function, body extracted from
11007 compute_line_metrics.
11008 (compute_line_metrics): Call row_hash, instead of computing the
11011 * dispnew.c (verify_row_hash): Call row_hash for computing the
11012 hash code of a row, instead of duplicating code from xdisp.c.
11014 * dispextern.h (row_hash): Add prototype.
11016 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
11018 * frame.c (delete_frame): Don't delete the terminal when the last

11054 * xdisp.c (display_line): Move the call to
11055 highlight_trailing_whitespace before the call to
11056 compute_line_metrics, since the latter needs to see the final
11057 faces of all the glyphs to compute ROW's hash value.
11058 Fixes assertion violations in row_equal_p. (Bug#10035)
11060 2011-11-14 Juanma Barranquero <lekktu@gmail.com>

11067 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
11068 with user-defined heap size. Bump the default size of the temacs

11072 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
11073 current_matrix and desired_matrix. (Bug#9990)
11074 (verify_row_hash) [XASSERTS]: New function.

11200 (window_box_right, window_box_right_offset): Declare extern.
11201 Otherwise, these inline functions do not conform to C99 and
11202 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
11203 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
11204 * intervals.c (adjust_intervals_for_insertion)
11205 (adjust_intervals_for_deletion): Now extern, because otherwise the
11206 extern inline functions 'offset_intervals' couldn't refer to it.
11207 (static_offset_intervals): Remove.
11208 (offset_intervals): Rewrite using the old contents of
11209 static_offset_intervals. The old version didn't conform to C99
11210 because an extern inline function contained a reference to an
11211 identifier with static linkage.
11213 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
11215 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

11233 (Fwindow_vscroll): Doc fix.
11234 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
11235 argument, since it makes no sense to pass a live window and for
11236 consistency with window-child.

11277 official. Move initialization of image_cache_refcount and
11278 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

11447 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
11448 instead of calling the "wide" APIs directly.

11463 * process.c (make_process): Set gnutls_state to NULL.
11465 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
11466 non-NULL, regardless of GNUTLS_INITSTAGE.
11467 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal

11515 (bidi_resolve_weak): Don't enter the expensive loop if the current
11516 position is before next_en_pos. Record the bidi type of the first
11517 non-ET, non-BN character we find, in addition to its position.
11518 (bidi_level_of_next_char): Invalidate next_en_type when
11519 next_en_pos is over-stepped.
11521 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
11523 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
11524 * editfns.c: Rewrite current-time-zone so that it invokes
11525 the equivalent of (format-time-string "%Z") to get the time zone name.
11526 This fixes a bug when the time zone name contains characters that
11527 need converting from the system time locale to Emacs internal format.
11528 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
11529 that patch fixed format-time-string to do the conversion, but
11530 I forgot to fix current-time-zone.
11531 (format_time_string): New function, containing most of
11532 what Fformat_time_string used to contain.
11533 (Fformat_time_string): Rewrite in terms of format_time_string.
11534 This doesn't change this function's behavior.
11535 (current-time-zone): Rewrite to use format_time_string.
11536 This fixes the bug reported by Michael Schierl in
11537 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
11538 Jason Rumney's 2007-06-07 change worked around this bug, but
11540 * systime.h (tzname, timezone): Remove no-longer-used declarations.
11542 2011-10-19 Eli Zaretskii <eliz@gnu.org>
11544 * xdisp.c (start_display): If the character at POS is displayed
11545 via a display vector, reset IT->current.dpvec_index to zero.
11546 (try_window_reusing_current_matrix): If a line ends in a display
11547 vector or the next line starts in a display vector, continue
11548 redrawing the window even though the character position of
11549 start_row was reached.
11552 2011-10-18 Chong Yidong <cyd@gnu.org>
11554 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
11555 with nobreak-char-display too.
11557 2011-10-18 Eli Zaretskii <eliz@gnu.org>
11559 Fix part 3 of bug#9771.
11560 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
11561 (bidi_resolve_neutral): Don't enter the expensive loop looking for
11562 non-neutral characters if the current character is a paragraph
11563 separator (a.k.a. Newline). This avoids running the same
11564 expensive loop twice, once when we consume the preceding newline
11565 and the other time when the line actually needs to be displayed.
11566 Avoid the loop when we see neutrals on the base embedding level
11567 following a character whose directionality is the same as the
11568 paragraph's. This avoids running the expensive loop when a line
11569 ends in a long sequence of neutrals, like control characters.
11570 Add assertion against STRONG_AL type. Slightly rearrange code
11571 that determines the type of a neutral given the first non-neutral
11573 (bidi_level_of_next_char): Set next_en_pos to zero when
11574 invalidating its info.
11576 2011-10-17 Eli Zaretskii <eliz@gnu.org>
11578 * xdisp.c (push_display_prop): Determine whether to record string
11579 or buffer position by IT->string, not by IT->method. Allow
11580 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
11581 (move_it_vertically_backward): Don't look for character position
11582 immediately after the newline when in a continuation line.
11585 2011-10-15 Martin Rudalics <rudalics@gmx.at>
11587 * window.c (coordinates_in_window): Rewrite and delabelize
11588 vertical border check. (Bug#5357) (Bug#9618)
11590 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
11592 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
11593 errors in XSetWindowBorder (bug#9310).
11595 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
11597 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
11598 avoid crash when xmalloc overrun checking is enabled.
11600 2011-10-13 Eli Zaretskii <eliz@gnu.org>
11602 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
11603 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
11604 cursor motion with <left> and <right> arrow keys.
11606 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
11607 some callers set that themselves.
11609 2011-10-12 Eli Zaretskii <eliz@gnu.org>
11611 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
11612 display string and the previous row comes from the same string and
11613 is empty. (Bug#9739) (Bug#9738)
11615 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
11617 * doc.c (get_doc_string): Encode file name (bug#9735).
11619 2011-10-12 Eli Zaretskii <eliz@gnu.org>
11621 * bidi.c (bidi_level_of_next_char):
11622 * xdisp.c (get_visually_first_element): Remove old incorrect
11623 comments regarding the Unicode Line Separator character.
11625 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
11627 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>

11630 boundary if nzombies > MAX_ZOMBIES.
11631 * alloc.c (dump_zombies): Add missing format specifier.
11633 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
11635 * xdisp.c (set_cursor_from_row): Simplify conditionals,
11636 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
11638 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
11639 Some packages use them to denote characters with modifiers.
11641 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
11643 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
11644 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
11645 matching a pp-number. Rename parameter var to var1.
11647 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
11649 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).

11653 * callint.c (Fcall_interactively): Give a more explicit error for the
11654 'c' case with a non-character input. (Bug#8479)
11656 2011-10-08 Eli Zaretskii <eliz@gnu.org>
11658 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
11660 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
11661 lines that are hscrolled on the left.
11663 * dispnew.c (buffer_posn_from_coords): Account for a possible
11664 presence of header-line. (Bug#4426)
11666 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
11668 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
11669 Don't advertise functionality which we discourage or doesn't work.
11671 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
11673 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
11674 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
11675 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
11676 this makes Emacs dump core during garbage collection on rare
11677 occasions. sizeof is obviously inferior to offsetof here, so
11678 stick with offsetof.
11679 (GC_POINTER_ALIGNMENT): New macro.
11680 (mark_memory): Omit 3rd (offset) arg; caller changed.
11681 Don't assume EMACS_INT alignment is the same as pointer alignment.
11683 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
11685 * keyboard.c (read_key_sequence_remapped): New var.
11686 (read_key_sequence): Compute remapping in the right buffer.
11687 (command_loop_1): Use read_key_sequence's remapping directly.
11689 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
11691 * dired.c (file_name_completion): Don't expand file name.
11692 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
11693 before checking file name handler.
11695 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
11696 they've been requested explicitly (bug#9591).
11698 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
11700 * keymap.c (Fsingle_key_description): Use make_specified_string
11701 instead of build_string to build string from push_key_description.
11704 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
11706 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
11707 This fixes a Y2038 bug on 64-bit hosts.
11708 * buffer.c (reset_buffer):
11709 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
11710 (Fclear_buffer_auto_save_failure):
11711 Use 0, not -1, to represent an unset failure time, since time_t
11712 might not be signed.
11714 Remove dependency on glibc malloc internals.
11715 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11716 Move back here from lisp.h, but with their new implementations.
11717 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11718 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
11719 * charset.c (charset_table_init): New static var.
11720 (syms_of_charset): Use it instead of xmalloc. This removes a
11721 dependency on glibc malloc internals. See Eli Zaretskii's comment in
11722 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
11723 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11724 Move back to alloc.c.
11725 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11726 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
11728 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
11730 * nsterm.m (windowDidResize): Call x_set_window_size only when
11731 ns_in_resize is true. Otherwise set pixelwidth/height and
11732 call change_frame_size (Bug#9628).
11734 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
11736 Port --enable-checking=all to Fedora 14 x86-64.
11737 * charset.c (syms_of_charset): Also account for glibc malloc's
11738 internal overhead when calculating the initial malloc maximum.
11740 Port --enable-checking=all to Fedora 14 x86.
11741 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11743 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
11744 (overrun_check_realloc, overrun_check_free):
11745 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
11746 That way, xmalloc returns a properly-aligned pointer even if
11747 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
11748 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
11749 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
11750 into account when calculating the initial malloc maximum.
11751 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11752 Move here from alloc.c, so that charset.c can use it too.
11753 Properly align; the old code wasn't right for common 32-bit hosts
11754 when configured with --enable-checking=all.
11755 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11756 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
11758 2011-09-29 Eli Zaretskii <eliz@gnu.org>
11760 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
11763 2011-09-28 Eli Zaretskii <eliz@gnu.org>
11765 * xdisp.c (compute_display_string_end): If there's no display
11766 string at CHARPOS, return -1.
11768 * bidi.c (bidi_fetch_char): When compute_display_string_end
11769 returns a negative value, treat the character as a normal
11770 character not covered by a display string. (Bug#9624)
11772 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
11774 * lread.c (Fread_from_string): Fix typo in docstring.
11776 2011-09-27 Eli Zaretskii <eliz@gnu.org>
11778 * xdisp.c (handle_invisible_prop): If invisible text ends on a
11779 newline, reseat the iterator instead of bidi-iterating there one
11780 character at a time. (Bug#9610)
11781 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
11782 TO_CHARPOS if the bidi iterator is at base embedding level.
11784 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
11786 * lread.c (readevalloop): Use correct code for NBSP.
11787 (read1): Likewise. (Bug#9608)
11789 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
11791 * dbusbind.c (Fdbus_register_signal): When service is not
11792 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
11794 2011-09-25 Glenn Morris <rgm@gnu.org>
11796 * buffer.c (truncate-lines): Doc fix.
11798 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
11800 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
11801 (Fset_window_next_buffers): Doc fix.
11803 2011-09-24 Glenn Morris <rgm@gnu.org>
11805 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
11807 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
11809 Fix minor problems found by static checking.
11810 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
11811 * indent.c (Fvertical_motion): Fix == vs = typo.
11813 2011-09-24 Eli Zaretskii <eliz@gnu.org>
11815 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
11816 Default value is now t. Doc fix.
11818 * indent.c (Fvertical_motion): Compute and apply the overshoot
11819 logic when moving up, not only when moving down. Fix the
11820 confusing name and values of the it_overshoot_expected variable;
11821 logic changes accordingly. (Bug#9254) (Bug#9549)
11823 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
11824 CHARPOS is covered by a display string which includes newlines.
11825 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
11826 is covered by a display string with embedded newlines.
11828 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
11830 * dbusbind.c (Fdbus_register_signal): Add match rule to
11831 Vdbus_registered_objects_table. (Bug#9581)
11832 (Fdbus_register_method, Vdbus_registered_objects_table):
11835 2011-09-24 Jim Meyering <meyering@redhat.com>
11837 do not ignore write error for any output size
11838 The previous change was incomplete.
11839 While it makes emacs --batch detect the vast majority of stdout
11840 write failures, errors were still ignored whenever the output size is
11841 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
11842 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
11843 && echo FAIL: ignored write error
11844 FAIL: ignored write error
11845 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
11846 && echo FAIL: ignored write error
11847 FAIL: ignored write error
11848 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
11850 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
11852 * emacs.c (Fkill_emacs): In noninteractive mode exit
11853 non-successfully if a write error occurred on stdout. (Bug#9574)
11855 2011-09-21 Eli Zaretskii <eliz@gnu.org>
11857 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
11860 * dispextern.h (struct it): Update the comment documenting what
11863 2011-09-20 Eli Zaretskii <eliz@gnu.org>
11865 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
11866 a display string, extend search for cursor position to end of row.
11867 (find_row_edges): If the row ends in a newline from a display
11868 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
11869 Handle the case of a display string with multiple newlines.
11870 (Fcurrent_bidi_paragraph_direction): Fix search for previous
11871 non-empty line. Fixes confusing cursor motion with arrow keys at
11872 the beginning of a line that starts with whitespace.
11874 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
11876 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
11879 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
11881 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
11882 boolean (Bug#9154).
11884 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11886 * xdisp.c (display_line): Record maximum and minimum buffer
11887 positions even if no glyphs were produced (e.g., by a zero-width
11888 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
11889 buffer positions that will be removed from the glyph row because
11891 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
11892 column is beyond frame width: don't subtract 1 "pixel" when
11893 computing width of the stretch.
11894 (reseat_at_next_visible_line_start): Undo the change made on
11895 2011-09-17 that saved paragraph information and restored it after
11896 the call to `reseat'. (Bug#9545)
11898 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11900 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
11901 and turn window cursor on if cleared (Bug#9415).
11903 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
11905 * search.c (boyer_moore): Take unibyte characters from pattern
11906 literally. (Bug#9458)
11908 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11910 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
11912 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
11914 Fix minor problem found by static checking.
11915 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
11916 initialized, to pacify gcc -Wuninitialized.
11918 * fileio.c: Report proper errno when syscall falls.
11919 (Finsert_file_contents): Save and restore errno,
11920 so that report_file_error outputs the correct diagnostic.
11921 (Fwrite_region) [CLASH_DETECTION]: Likewise.
11923 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11925 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
11927 2011-09-17 Eli Zaretskii <eliz@gnu.org>
11929 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
11930 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
11932 2011-09-17 Eli Zaretskii <eliz@gnu.org>
11934 * xdisp.c (reseat_at_next_visible_line_start): Keep information
11935 about the current paragraph and restore it after the call to reseat.
11937 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
11938 (bidi_find_paragraph_start): Search back for paragraph beginning
11939 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
11940 (bidi_move_to_visually_next): Only trigger paragraph-related
11941 computations when the last character is a newline or at EOB, not
11942 just any NEUTRAL_B. (Bug#9470)
11944 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
11945 truncated lines if point is covered by a display string. (Bug#9524)
11947 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
11949 * xselect.c: Relax test for outgoing X longs (Bug#9498).
11950 (cons_to_x_long): New function.
11951 (lisp_data_to_selection_data): Use it. Correct the test for
11952 short-versus-long data; it was negated. Break out of vector
11953 loop, for efficiency, when a long datum is discovered.
11955 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
11957 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
11959 2011-09-16 Eli Zaretskii <eliz@gnu.org>
11961 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
11962 GCC PR/17406) by declaring this function with external scope.
11964 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
11966 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
11967 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
11969 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
11971 * editfns.c (Fformat): Correctly handle text properties on "%%".
11973 2011-09-15 Eli Zaretskii <eliz@gnu.org>
11975 * xterm.c (x_draw_composite_glyph_string_foreground):

11977 * term.c (encode_terminal_code):
11978 * composite.c (composition_update_it, get_composition_id):
11979 * xdisp.c (get_next_display_element)
11980 (fill_composite_glyph_string): Add comments about special meaning
11981 of TAB characters in a composition.
11983 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
11985 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
11986 This occurs when processing a multibyte format.
11987 Problem reported by Wolfgang Jenker.
11989 2011-09-15 Johan Bockgård <bojohan@gnu.org>
11991 * xdisp.c (try_cursor_movement): Only check for exact match if
11992 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
11994 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
11996 Remove unused external symbols.
11997 * dispextern.h (calc_pixel_width_or_height): Remove decl.
11998 * xdisp.c (calc_pixel_width_or_height): Now static.
11999 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
12000 * indent.c (check_display_width):
12001 * w32term.c: Fix comment to match code.
12002 * xterm.c, xterm.h (x_catching_errors): Remove.
12004 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
12006 * xselect.c: Use signed conversions more consistently (Bug#9498).
12007 (selection_data_to_lisp_data): Assume incoming selection data are
12008 signed integers, not unsigned. This is to be consistent with
12009 outgoing selection data, which was modified to use signed integers
12010 in as part of the fix to Bug#9196 in response to Jan D.'s comment
12011 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
12012 expects long, not unsigned long.
12014 2011-09-14 Eli Zaretskii <eliz@gnu.org>
12016 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
12017 computation of loop end. Reported by Johan Bockgård
12020 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
12022 * frame.c (Fother_visible_frames_p): Function deleted.
12024 2011-09-12 Eli Zaretskii <eliz@gnu.org>
12026 * indent.c (compute_motion): Process display vector front to back
12027 rather than the other way around. (Bug#2496)
12029 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
12031 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
12033 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
12035 * minibuf.c (Fread_from_minibuffer): Doc fix.
12037 2011-09-11 Eli Zaretskii <eliz@gnu.org>
12039 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
12040 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
12042 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
12044 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
12045 value for non-existent files.
12047 2011-09-11 Eli Zaretskii <eliz@gnu.org>
12049 * fileio.c (Finsert_file_contents): If the file cannot be opened,
12050 set its "size" to -1. This will set the modtime_size field of
12051 the corresponding buffer to -1, which is what
12052 verify-visited-file-modtime expects for files that do not exist.
12055 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
12057 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
12059 * lisp.h: ... from here. push_key_description is no longer
12060 defined in keyboard.c, so its declaration should not be in
12061 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
12062 logically belongs with push_key_description.
12064 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
12066 * buffer.h: Include <sys/types.h> instead of <time.h>.
12067 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
12068 Problem reported by Herbert J. Skuhra.
12070 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
12072 * xml.c (parse_region): Make the parsing work for
12073 non-comment-starting XML files again (bug#9144).
12075 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
12077 * image.c (gif_load): Fix calculation of bottom and right corner.
12080 2011-09-10 Eli Zaretskii <eliz@gnu.org>
12082 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
12083 redisplay in small windows.
12085 2011-09-09 Eli Zaretskii <eliz@gnu.org>
12087 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
12089 2011-09-08 Martin Rudalics <rudalics@gmx.at>
12091 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
12092 Operate on live windows only.
12094 2011-09-08 Juanma Barranquero <lekktu@gmail.com>

12098 2011-09-07 Eli Zaretskii <eliz@gnu.org>
12100 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
12101 only under bidi iteration.
12103 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
12105 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
12107 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12109 isnan: Fix porting problem to Solaris 10 with bundled gcc.
12110 Without this fix, the command to link temacs failed due to an
12111 undefined symbol __builtin_isnan. This is because
12112 /usr/include/iso/math_c99.h #defines isnan(x) to
12113 __builtin_isnan(x), but the bundled gcc, which identifies itself
12114 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
12116 * floatfns.c (isnan): #undef, and then #define to a clone of
12118 (Fisnan): Always define, since it's always available now.
12119 (syms_of_floatfns): Always define isnan at the Lisp level.
12121 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12123 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
12125 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12127 * fileio.c: Fix bugs with large file offsets (Bug#9428).
12128 The previous code assumed that file offsets (off_t values) fit in
12129 EMACS_INT variables, which is not true on typical 32-bit hosts.
12130 The code messed up by falsely reporting buffer overflow in cases
12131 such as (insert-file-contents "big" nil 1 2) into an empty buffer
12132 when "big" contains more than 2**29 bytes, even though this
12133 inserts just one byte and does not overflow the buffer.
12134 (Finsert_file_contents): Store file offsets as off_t
12135 values, not as EMACS_INT values. Check for overflow when
12136 converting between EMACS_INT and off_t. When checking for
12137 buffer overflow or for overlap, take the offsets into account.
12138 Don't use EMACS_INT for small values where int suffices.
12139 When checking for overlap, fix a typo: ZV was used where
12140 ZV_BYTE was intended.
12141 (Fwrite_region): Don't assume off_t fits into 'long'.
12142 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
12144 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
12146 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
12148 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
12150 sprintf-related integer and memory overflow issues (Bug#9412).
12152 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
12153 (esprintf, exprintf, evxprintf): New functions.
12154 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
12155 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
12156 (modify_event_symbol): Do not assume that the length of
12157 name_alist_or_stem is safe to alloca and fits in int.
12158 (Fexecute_extended_command): Likewise for function name and binding.
12159 (Frecursion_depth): Wrap around reliably on integer overflow.
12160 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
12161 since some callers pass EMACS_INT values.
12162 (Fsingle_key_description): Don't crash if symbol name contains more
12163 than MAX_ALLOCA bytes.
12164 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
12165 (get_minibuffer): Arg is now EMACS_INT, not int.
12166 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
12167 (esprintf, exprintf, evxprintf): New decls.
12168 * window.h (command_loop_level, minibuf_level): Reflect API changes.
12170 * dbusbind.c (signature_cat): New function.
12171 (xd_signature, Fdbus_register_signal):
12172 Do not overrun buffer; instead, report string overflow.
12174 * dispnew.c (add_window_display_history): Don't overrun buffer.
12175 Truncate instead; this is OK since it's just a log.
12177 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
12178 even if the time zone offset is outlandishly large.
12179 Don't mishandle offset == INT_MIN.
12181 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
12182 when creating daemon; the previous buffer-overflow check was incorrect.
12184 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
12185 which has the guts of the old verror function.
12187 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
12188 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
12190 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
12191 (font_unparse_xlfd): Don't blindly alloca long strings.
12192 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
12193 fits in int, when using sprintf. Use single snprintf to count
12194 length of string rather than counting it via multiple sprintfs;
12195 that's simpler and more reliable.
12196 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
12197 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
12198 sprintf, in case result does not fit in int.
12200 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
12201 (fontset_from_font): Print it.
12203 * frame.c (tty_frame_count): Now printmax_t, not int.
12204 (make_terminal_frame, set_term_frame_name): Print it.
12205 (x_report_frame_params): In X, window IDs are unsigned long,
12206 not signed long, so print them as unsigned.
12207 (validate_x_resource_name): Check for implausibly long names,
12208 and don't assume name length fits in 'int'.
12209 (x_get_resource_string): Don't blindly alloca invocation name;
12210 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
12213 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
12214 (xg_check_special_colors, xg_set_geometry):
12215 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
12217 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
12218 Use esprintf, not sprintf, in case result does not fit in int.
12220 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
12221 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
12222 it as a large positive number.
12223 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
12224 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
12226 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
12227 in case result does not fit in int.
12229 * print.c (float_to_string): Detect width overflow more reliably.
12230 (print_object): Make sprintf buffer a bit bigger, to avoid potential
12231 buffer overrun. Don't assume list length fits in 'int'. Treat
12232 print length of 0 as 0, not as infinity; to be consistent with other
12233 uses of print length in this function. Don't overflow print length
12234 index. Don't assume hash table size fits in 'long', or that
12235 vectorlike size fits in 'unsigned long'.
12237 * process.c (make_process): Use printmax_t, not int, to format
12238 process-name gensyms.
12240 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
12242 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
12243 to avoid potential buffer overrun.
12245 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
12246 if X resource line is longer than 512 bytes.
12248 * xfns.c (x_window): Make sprintf buffer a bit bigger
12249 to avoid potential buffer overrun.
12251 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
12253 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
12255 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
12257 Integer overflow fixes for scrolling, etc.
12258 Without these, Emacs silently mishandles large integers sometimes.
12259 For example, "C-u 4294967297 M-x recenter" was treated as if
12260 it were "C-u 1 M-x recenter" on a typical 64-bit host.
12262 * xdisp.c (try_window_id): Check Emacs fixnum range before
12263 converting to 'int'.
12265 * window.c (window_scroll_line_based, Frecenter):
12266 Check that an Emacs fixnum is in range before assigning it to 'int'.
12267 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
12268 values converted from Emacs fixnums.
12269 (Frecenter): Don't wrap around a line count if it is out of 'int'
12270 range; instead, treat it as an extreme value.
12271 (Fset_window_configuration, compare_window_configurations):
12272 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
12274 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
12275 that can exceed INT_MAX. Check that EMACS_INT value is in range
12276 before assigning it to the (possibly-narrower) index.
12277 (match_limit): Don't assume that a fixnum can fit in 'int'.
12279 * print.c (print_object): Use ptrdiff_t, not int, for index that can
12282 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
12283 (Fvertical_motion): Don't wrap around LINES values that don't fit
12284 in 'int'. Instead, treat them as extreme values. This is good
12285 enough for windows, which can't have more than INT_MAX lines anyway.
12287 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
12289 * Require libxml/parser.h to avoid compilation warning.
12291 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
12293 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
12294 since this reportedly can destroy thread storage.
12296 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
12298 * syntax.c (find_defun_start): Update all cache variables if
12299 exiting early (Bug#9401).
12301 2011-08-30 Eli Zaretskii <eliz@gnu.org>
12303 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
12305 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
12306 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
12307 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
12309 * term.c (tty_append_glyph): New function.
12310 (produce_stretch_glyph): Static function and its prototype deleted.
12312 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
12315 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
12317 * image.c (parse_image_spec): Check for nonnegative, not for positive,
12318 when checking :margin (Bug#9390).
12319 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
12320 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
12321 so that the name doesn't mislead. All uses changed.
12323 2011-08-28 Johan Bockgård <bojohan@gnu.org>
12325 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
12328 2011-08-27 Eli Zaretskii <eliz@gnu.org>
12330 * xdisp.c (move_it_to): Don't bail out early when reaching
12331 position beyond to_charpos, if we are scanning backwards.
12332 (move_it_vertically_backward): When DY == 0, make sure we get to
12333 the first character in the line after the newline.
12335 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
12337 * ccl.c: Improve and simplify overflow checking (Bug#9196).
12338 (ccl_driver): Do not generate an out-of-range pointer.
12339 (Fccl_execute_on_string): Remove unnecessary check for
12340 integer overflow, noted by Stefan Monnier in
12341 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
12342 Remove a FIXME that didn't need fixing.
12343 Simplify the newly-introduced buffer reallocation code.
12345 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
12347 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
12349 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
12351 Integer and memory overflow issues (Bug#9196).
12353 * doc.c (get_doc_string): Rework so that
12354 get_doc_string_buffer_size is the actual buffer size, rather than
12355 being 1 less than the actual buffer size; this makes xpalloc more
12358 * image.c (x_allocate_bitmap_record, cache_image):
12359 * xselect.c (Fx_register_dnd_atom):
12360 Simplify previous changes by using xpalloc.
12362 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
12363 since either will do and ptrdiff_t is convenient with xpalloc.
12365 * charset.c (charset_table_size)
12366 (struct charset_sort_data.priority): Now ptrdiff_t.
12367 (charset_compare): Don't overflow if priorities differ greatly.
12368 (Fsort_charsets): Don't assume list length fits in int.
12369 Check for size-calculation overflow when allocating sort data.
12370 (syms_of_charset): Allocate an initial charset table that is
12371 just under 64 KiB, to avoid problems with glibc malloc and mmap.
12373 * cmds.c (internal_self_insert): Check for size-calculation overflow.
12375 * composite.h (struct composition.glyph_len): Now int, not unsigned.
12376 The actual value is always <= INT_MAX, and leaving it unsigned made
12377 overflow checking harder.
12379 * dispextern.h (struct glyph_matrix.rows_allocated)
12380 (struct face_cache.size): Now ptrdiff_t, for convenience in use
12381 with xpalloc. The values are still always <= INT_MAX.
12383 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
12385 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
12386 (SAFE_NALLOCA): New macro.
12388 * region-cache.c (struct boundary.pos, find_cache_boundary)
12389 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
12390 (set_cache_region, invalidate_region_cache)
12391 (revalidate_region_cache, know_region_cache, region_cache_forward)
12392 (region_cache_backward, pp_cache):
12393 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
12394 so that ptrdiff_t * can be passed to xpalloc.
12395 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
12396 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
12397 (pp_cache): Don't assume cache_len fits in int.
12398 * region-cache.h: Adjust extern decls to match.
12400 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
12401 EMACS_INT, since either will do, for xpalloc.
12403 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
12404 (xnmalloc, xnrealloc, xpalloc): New functions.
12406 * bidi.c (bidi_shelve_header_size): New constant.
12407 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
12408 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
12410 * bidi.c (bidi_cache_shrink):
12411 * buffer.c (overlays_at, overlays_in, record_overlay_string)
12413 Don't update size of array until after memory allocation succeeds,
12414 because xmalloc/xrealloc may not return.
12415 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
12416 now that we have proper integer overflow checking.
12417 (record_overlay_string, overlay_strings): Catch overflows when
12418 calculating size of overlay_str_buf.
12420 * callproc.c (Fcall_process): Check for size overflow when
12421 calculating size of args2.
12422 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
12423 Normally we prefer signed values, but sticking with ptrdiff_t would
12424 require adding more-complicated checks.
12426 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
12427 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
12428 Redo buffer-overflow calculations to avoid integer overflow.
12429 Add a FIXME comment where memory seems to be over-allocated.
12431 * character.c (Fstring): Check for size-calculation overflow.
12433 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
12434 unnecessary integer overflow. Check for size overflow.
12435 (encode_coding_object): Don't update size until xmalloc succeeds.
12437 * composite.c (get_composition_id): Check for overflow in glyph
12438 length calculations.
12440 Integer and memory overflow fixes for display code.
12441 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
12442 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
12443 (scrolling_window): Check for overflow in size calculations.
12444 (line_draw_cost, realloc_glyph_pool, add_row_entry):
12445 Don't assume glyph table len fits in int.

12447 (row_table_size): Now ptrdiff_t, not int.
12448 (scrolling_window): Avoid overflow in size calculations.
12449 Don't update size until allocation succeeds.
12450 * fns.c (concat): Check for overflow in size calculations.
12451 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
12452 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
12453 (NEXT_ALMOST_PRIME_LIMIT): New constant.
12455 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
12456 (get_doc_string): Check for size calculation overflow.
12457 Don't update size until allocation succeeds.
12458 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
12459 EMACS_INT, where ptrdiff_t will do.
12460 (Fsubstitute_command_keys): Check for string overflow.
12462 * editfns.c (set_time_zone_rule): Don't assume environment length
12464 (message_length): Now ptrdiff_t, not int.
12465 (Fmessage_box): Don't update size until allocation succeeds.
12466 Don't assume message length fits in int.
12467 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
12469 * emacs.c (main): Do not reallocate argv, since there is a null at
12470 the end that can be overwritten, and this way there's no need to
12471 worry about size-calculation overflow.
12472 (sort_args): Check for size-calculation overflow.
12474 * eval.c (init_eval_once, grow_specpdl): Don't update size until
12476 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
12478 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
12479 (x_set_scroll_bar_width, x_figure_window_size):
12480 Check for integer overflow.
12481 (x_set_alpha): Do not assume XINT fits in int.
12483 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
12484 This is for the members text_lines, text_cols, total_lines, total_cols,
12485 where the system imposes an 'int' limit.
12487 * fringe.c (Fdefine_fringe_bitmap):
12488 Don't update size until alloc works.
12490 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
12491 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
12493 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
12494 Check for size-calculation overflow.
12495 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
12496 do, as we prefer signed integers.
12497 (id_to_widget.max_size, id_to_widget.used)
12498 (xg_store_widget_in_map, xg_remove_widget_from_map)
12499 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
12500 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
12501 Use and return ptrdiff_t, not int.
12502 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
12503 * gtkutil.h: Change prototypes to match the above.
12505 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
12506 are duplicate now that they've been promoted to lisp.h.
12507 (x_allocate_bitmap_record, x_alloc_image_color)
12508 (make_image_cache, cache_image, xpm_load):
12509 Don't update size until alloc is done.
12510 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
12512 Check for size calculation overflow.
12513 (ct_colors_allocated_max): New constant.
12514 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
12517 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
12518 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
12519 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
12520 Use ptrdiff_t, not int, to count maps.
12521 (read_char_minibuf_menu_prompt): Check for overflow in size
12522 calculations. Don't update size until allocation succeeds.
12523 Redo calculations to avoid overflow.
12524 * keyboard.h: Change prototypes to match the above.
12526 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
12528 (current_minor_maps): Check for size calculation overflow.
12529 * keymap.h: Change prototypes to match the above.
12531 * lread.c (read1, init_obarray): Don't update size until alloc done.
12533 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
12534 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
12536 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
12537 Now ptrdiff_t, not int.
12538 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.
12539 (ns_draw_fringe_bitmap): Rewrite to avoid overflow.
12541 * process.c (Fnetwork_interface_list): Check for overflow
12542 in size calculation.
12544 * region-cache.c (move_cache_gap): Check for size calculation overflow.
12546 * scroll.c (do_line_insertion_deletion_costs): Check for size calc
12547 overflow. Don't bother calling xmalloc when xrealloc will do.

12550 (Fset_match_data): Don't assume list lengths fit in 'int'.
12552 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
12553 for command line length. Do not attempt to address one before the
12554 beginning of an array, as that's not portable.
12556 * term.c (max_frame_lines): Remove; unused.

12562 table lengths and related sizes. Don't update size until alloc
12563 done. Redo calculations to avoid overflow.
12564 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
12566 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
12567 subtracting pointers.
12568 (gobble_line): Check for overflow more carefully. Don't update size
12571 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
12572 Don't update size until alloc done.
12573 Redo size calculations to avoid overflow.
12574 Check for size calculation overflow.

12582 Use ptrdiff_t, not int, for sizes.
12583 (Finternal_make_lisp_face, cache_face):
12584 Check for size calculation overflow.
12585 (cache_face): Treat size calculation overflows as if they were
12586 memory exhaustion (the usual treatment), rather than aborting.
12588 * xfns.c (x_encode_text, x_set_name_internal)
12589 (Fx_change_window_property): Use ptrdiff_t, not int, to count
12590 sizes, since they can exceed INT_MAX in size. Check for size
12591 calculation overflow.
12593 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
12594 (xg_select): Check for size calculation overflow.
12595 Don't update size until alloc done.
12597 * xrdb.c (get_environ_db): Don't assume path length fits in int,
12598 as sprintf is limited to int lengths.
12600 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
12601 (X_LONG_MIN): New macros.
12602 Use them to make the following changes clearer.
12603 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
12604 This change doesn't affect the value now, but it may help remind
12605 future maintainers not to raise the value too much later.
12606 (SELECTION_QUANTUM): Remove, replacing with ...
12607 (selection_quantum): ... new function, which avoids overflow.
12609 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
12610 assumption that selection length fits in 'int'.
12611 (x_reply_selection_request, x_handle_selection_request)
12612 (x_get_window_property, receive_incremental_selection)
12613 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
12614 (lisp_data_to_selection_data, clean_local_selection_data):

12616 (x_reply_selection_request, x_get_window_property)
12617 (receive_incremental_selection, x_property_data_to_lisp):
12618 Redo calculations to avoid overflow.
12619 (x_reply_selection_request): When sending hint, ceiling it at
12620 X_LONG_MAX rather than relying on wraparound overflow to send
12622 (x_get_window_property, receive_incremental_selection)
12623 (lisp_data_to_selection_data, x_property_data_to_lisp):
12624 Check for size-calculation overflow.

12627 Don't store size until memory allocation succeeds.
12628 (x_get_window_property): Plug memory leak on memory exhaustion.
12629 Don't double-block input; malloc is safe here. Don't assume 2**34
12630 - 4 fits in unsigned long. Add an xassert to check
12631 XGetWindowProperty overflow. Be more careful about overflow
12632 calculations, and distinguish size from memory overflow better.
12633 (receive_incremental_selection): When tracing, don't assume
12634 unsigned int is less than INT_MAX.
12635 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
12636 harmful) conversions of unsigned short to int.
12637 (lisp_data_to_selection_data): Don't assume that integers
12638 in the range -65535 through -1 fit in an X unsigned short.
12639 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
12640 result parameters unless successful. Rely on cons_to_unsigned
12641 to report problems with elements; the old code wasn't right anyway.
12642 (x_check_property_data): Check for int overflow; we cannot use
12643 a wider type due to X limits.
12644 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
12646 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
12648 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
12649 (x_term_init): Check for size calculation overflow.
12650 (x_color_cells): Don't store size until memory allocation succeeds.
12651 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
12652 Don't assume alloca size is less than MAX_ALLOCA.
12653 (x_term_init): Don't assume length fits in int (sprintf is limited
12656 Use ptrdiff_t for composition IDs.

12675 * image.c (xpm_get_color_table_h):
12676 * lisp.h (hash_lookup, hash_put):
12677 * minibuf.c (Ftest_completion):
12678 Use ptrdiff_t for hash table indexes, not int (which is too
12679 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
12680 32-bit --with-wide-int hosts).
12682 * charset.c (Fdefine_charset_internal): Check for integer overflow.
12683 Add a FIXME comment about memory leaks.
12684 (syms_of_charset): Don't assume xmalloc returns.

12691 with outlandish widths.
12692 * character.h (sanitize_tab_width): Rename from sanitize_width,
12693 now that we have two such functions. All uses changed.

12705 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
12707 * charset.c (read_hex): New arg OVERFLOW. All uses changed.

12711 * xterm.c: Don't go over XClientMessageEvent limit.
12712 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
12713 (x_send_scroll_bar_event): Likewise. Check that the size does not
12714 exceed limits imposed by XClientMessageEvent, as well as the usual
12715 ptrdiff_t and size_t limits.
12717 * keyboard.c: Overflow, signedness and related fixes.
12718 (make_lispy_movement): Use same integer type in forward decl
12719 that is used in the definition.
12720 (read_key_sequence, keyremap_step):
12721 Change bufsize argument back to int, undoing my 2011-03-30 change.
12722 We prefer signed types, and int is wide enough here.
12723 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
12724 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
12725 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
12726 length, not size_t. Use ptrdiff_t for index, not int.
12727 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
12728 possibility of integer overflow.
12730 Overflow, signedness and related fixes for images.
12732 * dispextern.h (struct it.stack[0].u.image.image_id)

12740 * xdisp.c (calc_pixel_width_or_height):
12741 * xfns.c (image_cache_refcount):

12751 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
12752 (lookup_image): Remove unnecessary tests.
12753 (xbm_image_p): Locals are now of int, not EMACS_INT,
12754 since parse_image_check makes sure they fit into int.
12755 (png_load, gif_load, svg_load_image):
12756 Prefer int to unsigned where either will do.
12757 (tiff_handler): New function, combining the cores of the
12758 old tiff_error_handler and tiff_warning_handler.
12759 This function is rewritten to use vsnprintf and thereby avoid
12760 stack buffer overflows. It uses only the features of vsnprintf
12761 that are common to both POSIX and native Microsoft.
12762 (tiff_error_handler, tiff_warning_handler): Use it.
12763 (tiff_load, gif_load, imagemagick_load_image):
12764 Don't assume :index value fits in 'int'.
12765 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
12766 (imagemagick_load_image): Check that crop parameters fit into
12767 the integer types that MagickCropImage accepts. Don't assume
12768 Vimagemagick_render_type has a nonnegative value. Don't assume
12769 size_t fits in 'long'.
12770 (gs_load): Use printmax_t to print the widest integers possible.
12771 Check for integer overflow when computing image height and width.
12773 2011-08-26 Eli Zaretskii <eliz@gnu.org>
12775 * xdisp.c (redisplay_window): Don't force window start if point
12776 will be invisible in the resulting window. (Bug#9324)

12780 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
12781 the display spec is of the form `(space ...)'.
12782 (handle_display_spec): Return the value returned by
12783 handle_single_display_spec, not just 1 or zero.
12784 (handle_single_display_spec): If the display spec is of the form
12785 `(space ...)', and specifies display in the text area, return 2
12787 (try_cursor_movement): Check for the need to scroll more
12788 accurately, and prefer exact match for point under bidi.
12789 Don't advance `row' beyond the last row of the window.
12791 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
12792 into disp_prop; all users changed.
12794 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns

12806 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
12807 buffers, return left-to-right.
12808 (set_cursor_from_row): Consider candidate row a win if its glyph
12809 represents a newline and point is on that newline. Fixes cursor
12810 positioning on the newline at EOL of R2L text within L2R
12811 paragraph, and vice versa.
12812 (try_cursor_movement): Check continued rows, in addition to
12813 continuation rows. Fixes unwarranted scroll when point enters a
12814 continued line of R2L text within an L2R paragraph, or vice versa.
12815 (cursor_row_p): Consider the case of point being equal to
12816 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
12817 from the end of a short line to the beginning of a continued line
12818 of R2L text within L2R paragraph.
12819 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
12820 composed characters.

12845 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
12846 instead of CHAR_TO_BYTE. Fixes a crash when a completion
12847 candidate is selected by the mouse, and that candidate has a
12848 composed character under the mouse.
12850 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
12851 coordinates reported by pos-visible-in-window-p for a composed
12852 character in column zero.
12854 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
12856 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
12858 2011-08-22 Eli Zaretskii <eliz@gnu.org>
12860 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
12861 consider it a hit if to_charpos is anywhere in the range of the
12862 composed buffer positions.
12864 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
12866 * image.c (gif_load): Don't assume that each subimage has the same
12867 dimensions as the base image. Handle disposal method that is
12868 "undefined" by the gif spec (Bug#9335).
12870 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
12872 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

12877 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
12878 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
12879 from an Org mode buffer to a Speedbar frame.
12881 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
12882 a composition, take its buffer position from IT->cmp_it.charpos.
12883 Fixes cursor positioning at the beginning of a line that begins
12884 with a composed character.
12886 2011-08-18 Eli Zaretskii <eliz@gnu.org>
12888 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
12889 character bidirectional type, use STRONG_L instead. Fixes crashes
12890 in a buffer produced by `describe-categories'.
12892 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
12893 members before the level stack, so they would be saved and
12894 restored when copying iterator state. Fixes incorrect reordering
12895 around TABs covered by display properties.

12923 Fix memory allocation problems in Cygwin build (Bug#9273).
12925 * unexcw.c ( __malloc_initialized): Declare external variable.
12926 (fixup_executable): Force the dumped emacs to reinitialize malloc.
12928 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
12930 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the

12969 * xdisp.c (move_it_in_display_line_to): Don't invoke
12970 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
12971 ppos_it. Fixes vertical cursor motion when line beginning is
12972 covered by an image. (Bug#9296)
12974 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
12976 * nsterm.h (ns_run_ascript): Declare.

12983 the event loop. Get status from as_status (Bug#7276).
12985 * nsterm.m (sendEvent): If event is NSApplicationDefined and
12986 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
12987 the event loop (Bug#7276).

12998 Qgnutls_bootprop_..., all uses changed.
13000 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
13003 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
13005 * xfaces.c (Qframe_set_background_mode): Now static.
13006 * dispextern.h (Qframe_set_background_mode): Remove decl.
13008 * process.c (Fnetwork_interface_info): Declare local only if needed.
13010 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
13012 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
13013 (Fnetwork_interface_list): Allocate in increments of bytes instead
13014 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
13015 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
13017 (struct ifflag_def): notrailers is smart on OSX.
13018 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
13019 Get hardware address with getifaddrs if available.
13021 2011-08-12 Eli Zaretskii <eliz@gnu.org>
13023 * xdisp.c (iterate_out_of_display_property): xassert that
13024 IT->position is set to within IT->object's boundaries. Break from
13025 the loop as soon as EOB is reached; avoids infloops in redisplay
13026 when IT->position is set up wrongly due to some bug.
13027 Set IT->current to match the bidi iterator unconditionally.
13028 (push_display_prop): Allow GET_FROM_STRING as IT->method on
13029 entry. Force push_it to save on the stack the current
13030 buffer/string position, to be restored by pop_it. Fix flags in
13031 the iterator structure wrt the object coming from a display
13032 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
13033 properties. (Bug#9284)
13035 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
13037 * fontset.c (fontset_get_font_group): Add proper type checks.
13040 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13042 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
13043 and LC_VERSION_MIN_MACOSX.
13044 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
13045 (dump_it) [LC_FUNCTION_STARTS]: Use it.
13047 2011-08-08 Eli Zaretskii <eliz@gnu.org>
13049 * xdisp.c (forward_to_next_line_start): Allow to use the
13050 no-display-properties-and-no-overlays under bidi display.
13051 Set disp_pos in the bidi iterator to avoid searches for display
13052 properties and overlays.
13054 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
13056 * editfns.c (Fset_time_zone_rule): Document relationship with the
13059 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
13060 the font entity extracted from the cache (Bug#8109).
13062 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
13064 * composite.c (autocmp_chars): Don't reset point. That is done by
13065 restore_point_unwind (Bug#5984).
13067 2011-08-07 Juri Linkov <juri@jurta.org>
13069 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
13070 to show the arg `TIME' instead of `TIMEVAL'.
13072 2011-08-06 Eli Zaretskii <eliz@gnu.org>
13074 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
13075 display property strides EOL and includes a newline, as in
13076 longlines-mode. (Bug#9254)
13077 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
13078 word-wrap under bidirectional display. (Bug#9224)
13080 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
13081 is non-zero, even if the data buffer is NULL. Fixes a crash in
13082 vertical-motion with longlines-mode. (Bug#9254)
13084 2011-08-05 Eli Zaretskii <eliz@gnu.org>
13086 * bidi.c <bidi_cache_total_alloc>: Now static.
13087 (bidi_initialize): Initialize bidi_cache_total_alloc.
13089 * xdisp.c (display_line): Release buffer allocated for shelved bidi
13092 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
13093 amount allocated this far in `bidi_cache_total_alloc'.
13094 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
13095 non-zero, only free the data buffer without restoring the cache
13096 contents. All callers changed.
13098 * dispextern.h (bidi_unshelve_cache): Update prototype.
13100 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
13101 (move_it_in_display_line, move_it_to)
13102 (move_it_vertically_backward, move_it_by_lines): Replace the call
13103 to xfree to an equivalent call to bidi_unshelve_cache.
13104 (move_it_in_display_line_to): Fix logic of returning
13105 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
13107 2011-08-05 Eli Zaretskii <eliz@gnu.org>
13109 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
13110 came from a string character with a `cursor' property. (Bug#9229)
13112 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
13114 * Makefile.in (LIB_PTHREAD): New variable.
13115 (LIBES): Add LIB_PTHREAD (Bug#9216).
13117 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
13118 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
13120 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
13122 * regex.c (re_iswctype): Remove some redundant boolean conversions.
13124 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
13126 * xterm.c (x_find_topmost_parent): New function.
13127 (x_set_frame_alpha): Find topmost parent window with
13128 x_find_topmost_parent and set the property there also (bug#9181).
13129 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
13131 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
13133 * callproc.c (Fcall_process): Avoid vfork clobbering
13134 the local vars buffer, coding_systems, current_dir.
13136 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
13138 * keymap.c (Fmake_composed_keymap): Move to subr.el.
13140 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
13142 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
13143 so that it is not optimized away.
13145 * xdisp.c (compute_display_string_pos): Remove unused local.
13147 2011-08-02 Eli Zaretskii <eliz@gnu.org>
13149 Fix slow cursor motion and scrolling in large buffers with
13150 selective display, like Org Mode buffers. (Bug#9218)
13152 * dispextern.h (struct bidi_it): New member disp_prop_p.
13154 * xdisp.c: Remove one-slot cache of display string positions.
13155 (compute_display_string_pos): Accept an additional argument
13156 DISP_PROP_P; callers changed. Scan at most 5K characters forward
13157 for a display string or property. If found, set DISP_PROP_P
13160 * bidi.c (bidi_fetch_char): Accept an additional argument
13161 DISP_PROP_P, and pass it to compute_display_string_pos.
13162 Only handle text covered by a display string if DISP_PROP_P is returned
13163 non-zero. All callers of bidi_fetch_char changed.
13165 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
13167 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
13169 2010-12-03 Don March <don@ohspite.net>
13171 * keymap.c (Fdefine_key): Fix non-prefix key error message when
13172 last character M-[char] is translated to ESC [char] (bug#7541).
13174 2011-08-02 Kenichi Handa <handa@m17n.org>
13176 * lisp.h (uniprop_table): Extern it.
13178 * chartab.c (uniprop_table): Make it non-static.
13180 2011-08-01 Eli Zaretskii <eliz@gnu.org>
13182 * xdisp.c (forward_to_next_line_start): Accept additional argument
13183 BIDI_IT_PREV, and store into it the state of the bidi iterator had
13185 (reseat_at_next_visible_line_start): Use the bidi iterator state
13186 returned by forward_to_next_line_start to restore the state of
13187 it->bidi_it after backing up to previous newline. (Bug#9212)
13189 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
13191 * regex.c (re_comp): Protoize.
13192 (re_exec): Fix return type.
13193 (regexec): Fix type of `ret'. (Bug#9203)
13195 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13197 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
13198 This is needed if max-image-size is a floating-point number.
13200 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
13202 * print.c (print_object): Print empty symbol as ##.
13204 * lread.c (read1): Read ## as empty symbol.
13206 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
13208 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
13209 setting frame foreground color (Bug#9175).
13210 (x_set_background_color): Likewise.
13212 * nsmenu.m (-setText): Size tooltip dimensions precisely to
13213 contents (Bug#9176).
13214 (EmacsTooltip -init): Remove bezels and add shadows to
13217 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
13218 or scroll bar (Bug#8470).
13220 * nsfont.m (nsfont_open): Remove assignment to voffset and
13221 unnecessary vars hshink, expand, hd, full_height, min_height.
13222 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
13224 * nsterm.h (nsfont_info): Remove voffset field.
13226 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
13228 Implement strike-through and overline on NextStep (Bug#8863).
13230 * nsfont.m (nsfont_open): Use underline position provided by font,
13231 instead of hard-coded value of 2.
13232 (nsfont_draw): Call ns_draw_text_decoration instead.
13234 * nsterm.h: Add declaration for ns_draw_text_decoration.
13236 * nsterm.m (ns_draw_text_decoration): New function for drawing
13237 underline, overline, and strike-through.
13238 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
13239 ns_draw_text_decoration. Change treatment of cursor drawing to
13240 accommodate underlining, etc.
13242 2011-07-28 Eli Zaretskii <eliz@gnu.org>
13244 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
13247 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13249 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
13250 Without this fix, if a signal arrives just after memory fills up,
13251 'malloc' might be invoked reentrantly.
13253 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
13254 In other words, assume that every image size is allowed, on non-X
13255 hosts. This assumption is probably wrong, but it lets Emacs compile.
13257 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
13259 * regex.c (re_iswctype): Convert return values to boolean.
13261 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
13263 * xdisp.c (compute_display_string_pos): Don't use cached display
13264 string position if the buffer had its restriction changed.
13267 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13269 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
13271 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13273 Integer signedness and overflow and related fixes. (Bug#9079)
13275 * bidi.c: Integer size and overflow fixes.
13276 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
13277 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
13278 (bidi_cache_find_level_change, bidi_cache_ensure_space)
13279 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
13280 (bidi_find_other_level_edge):
13281 Use ptrdiff_t instead of EMACS_INT where either will do.
13282 This works better on 32-bit hosts configured --with-wide-int.
13283 (bidi_cache_ensure_space): Check for size-calculation overflow.
13284 Use % rather than repeated addition, for better worst-case speed.
13285 Don't set bidi_cache_size until after xrealloc returns, because it
13287 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
13288 (bidi_cache_ensure_space): Also check that the bidi cache size
13289 does not exceed that of the largest Lisp string or buffer. See Eli
13290 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
13292 * alloc.c (__malloc_size_t): Remove.
13293 All uses replaced by size_t. See Andreas Schwab's note
13294 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
13296 * image.c: Improve checking for integer overflow.
13297 (check_image_size): Assume that f is nonnull, since
13298 it is always nonnull in practice. This is one less thing to
13299 worry about when checking for integer overflow later.
13300 (x_check_image_size): New function, which checks for integer
13301 overflow issues inside X.
13302 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
13303 This removes the need for a memory_full check.
13304 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
13305 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
13306 (xbm_read_bitmap_data): Change locals back to 'int', since
13307 their values must fit in 'int'.
13308 (xpm_load_image, png_load, tiff_load):
13309 Invoke x_create_x_image_and_pixmap earlier,
13310 to avoid much needless work if the image is too large.
13311 (tiff_load): Treat overly large images as if
13312 x_create_x_image_and_pixmap failed, not as malloc failures.
13313 (gs_load): Use x_check_image_size.
13315 * gtkutil.c: Omit integer casts.
13316 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
13317 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
13319 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
13321 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
13322 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
13323 would wrongly return t on a 64-bit host.
13325 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
13326 The plain *_OVERFLOW macros run afoul of GCC bug 49705
13327 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
13328 and therefore cause GCC to emit a bogus diagnostic in some cases.
13330 * image.c: Integer signedness and overflow and related fixes.
13331 This is not an exhaustive set of fixes, but it's time to
13332 record what I've got.
13333 (lookup_pixel_color, check_image_size): Remove redundant decls.
13334 (check_image_size): Don't assume that arbitrary EMACS_INT values
13335 fit in 'int', or that arbitrary 'double' values fit in 'int'.
13336 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
13337 (tiff_load, imagemagick_load_image):
13338 Check for overflow in size calculations.
13339 (x_create_x_image_and_pixmap): Remove unnecessary test for
13340 xmalloc returning NULL; that can't happen.
13341 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
13342 (xpm_color_bucket): Use better integer hashing function.
13343 (xpm_cache_color): Don't possibly over-allocate memory.
13344 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
13345 (gif_memory_source):
13346 Use ptrdiff_t, not int or size_t, to record sizes.
13347 (png_load): Don't assume values greater than 2**31 fit in 'int'.
13348 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
13349 either works, as we prefer signed integers.
13350 (tiff_read_from_memory, tiff_write_from_memory):
13351 Return tsize_t, not size_t, since that's what the TIFF API wants.
13352 (tiff_read_from_memory): Don't fail simply because the read would
13353 go past EOF; instead, return a short read.
13354 (tiff_load): Omit no-longer-needed casts.
13355 (Fimagemagick_types): Don't assume size fits into 'int'.
13357 Improve hashing quality when configured --with-wide-int.
13358 * fns.c (hash_string): New function, taken from sxhash_string.
13359 Do not discard information about ASCII character case; this
13360 discarding is no longer needed.
13361 (sxhash-string): Use it. Change sig to match it. Caller changed.
13362 * lisp.h: Declare it.
13363 * lread.c (hash_string): Remove, since we now use fns.c's version.
13364 The fns.c version returns a wider integer if --with-wide-int is
13365 specified, so this should help the quality of the hashing a bit.
13367 * emacs.c: Integer overflow minor fix.
13368 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
13369 Define only if GNU_LINUX.
13370 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
13372 * dispnew.c: Integer signedness and overflow fixes.
13373 Remove unnecessary forward decls, that were a maintenance hassle.
13374 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
13376 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
13377 (scrolling_window): Use ptrdiff_t, not int, for byte count.
13378 (prepare_desired_row, line_draw_cost):
13379 Use int, not unsigned, where either works.
13380 (save_current_matrix, restore_current_matrix):
13381 Use ptrdiff_t, not size_t, where either works.
13382 (init_display): Check for overflow more accurately, and without
13383 relying on undefined behavior.
13385 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
13386 Remove, replacing with the new symbols in lisp.h. All uses changed.
13387 * fileio.c (make_temp_name):
13388 * filelock.c (lock_file_1, lock_file):
13389 * xdisp.c (message_dolog):
13390 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
13391 Use pMd etc. instead.
13392 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
13393 replacing the pWIDE etc. symbols removed from editfns.c.
13395 * keyboard.h (num_input_events): Now uintmax_t.
13396 This is (very slightly) less likely to mess up due to wraparound.
13399 * buffer.c: Integer signedness fixes.
13400 (alloc_buffer_text, enlarge_buffer_text):
13401 Use ptrdiff_t rather than size_t when either will do, as we prefer
13404 * alloc.c: Integer signedness and overflow fixes.
13405 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
13406 (__malloc_size_t): Default to size_t, not to int.
13407 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
13408 (Fgarbage_collect, mark_object_loop_halt, mark_object):
13409 Prefer ptrdiff_t to size_t when either would do, as we prefer
13411 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
13412 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
13413 Now const. Initialize with values that are in range even if char
13415 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
13416 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
13417 These functions do the right thing with sizes > 2**32.
13418 (check_depth): Now ptrdiff_t, not int.
13419 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
13420 Adjust to new way of storing sizes. Check for size overflow bugs
13422 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
13423 slightly wrong anyway, as it missed one instance of
13424 XMALLOC_OVERRUN_CHECK_OVERHEAD.
13425 (refill_memory_reserve): Omit needless cast to size_t.
13426 (mark_object_loop_halt): Mark as externally visible.
13428 * xselect.c: Integer signedness and overflow fixes.
13429 (Fx_register_dnd_atom, x_handle_dnd_message):
13430 Use ptrdiff_t, not size_t, since we prefer signed.
13431 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
13432 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
13433 x_dnd_atoms_size and x_dnd_atoms_length.
13435 * doprnt.c: Prefer signed to unsigned when either works.
13437 * doprnt.c (doprnt):
13439 * xdisp.c (vmessage):
13440 Use ptrdiff_t, not size_t, when using or implementing doprnt,
13441 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
13442 prefer signed arithmetic to avoid comparison confusion.
13443 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
13444 but is a bit tricky.
13446 Assume freestanding C89 headers, string.h, stdlib.h.
13447 * data.c, doprnt.c, floatfns.c, print.c:
13448 Include float.h unconditionally.
13449 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
13450 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
13451 * regex.c: Likewise for stddef.h, string.h.
13452 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
13453 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
13454 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
13455 (STDC_HEADERS): Remove obsolete defines.
13456 * sysdep.c: Include limits.h unconditionally.
13458 Assume support for memcmp, memcpy, memmove, memset.
13459 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
13460 * regex.c (memcmp, memcpy):
13461 Remove; we assume C89 now.
13463 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
13464 (__malloc_safe_bcopy): Remove; no longer needed.
13466 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
13467 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
13468 well either way, and we prefer signed to unsigned.
13470 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
13472 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
13473 closes the connection while we're reading (bug#9182).
13475 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
13477 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
13478 are specified (Bug#9168).
13480 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
13482 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
13483 Found by GCC static checking and --with-wide-int on a 32-bit host.
13485 2011-07-25 Eli Zaretskii <eliz@gnu.org>
13487 * xdisp.c (compute_display_string_pos): Fix logic of caching
13488 previous display string position. Initialize cached_prev_pos to
13489 -1. Fixes slow-down at the beginning of a buffer.
13491 2011-07-24 Eli Zaretskii <eliz@gnu.org>
13493 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
13494 for attrs[LFACE_FONTSET_INDEX].
13496 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
13498 * xml.c (parse_region): Remove unused local
13499 that was recently introduced.
13501 2011-07-23 Eli Zaretskii <eliz@gnu.org>
13503 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
13504 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
13506 * xdisp.c (move_it_in_display_line_to): Record the best matching
13507 position for TO_CHARPOS while scanning the line, and restore it on
13508 exit if none of the characters scanned was an exact match.
13509 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
13510 when exact match is impossible due to invisible text, and the
13511 lines are truncated.
13513 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
13515 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
13518 2011-07-22 Eli Zaretskii <eliz@gnu.org>
13520 Fix a significant slow-down of cursor motion with C-n, C-p,
13521 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
13522 auto-repeat under bidi redisplay in fontified buffers.
13523 * xdisp.c (compute_stop_pos_backwards): New function.
13524 (next_element_from_buffer): Call compute_stop_pos_backwards to
13525 find a suitable prev_stop when we find ourselves before
13527 (reseat): Don't look for prev_stop, as that could mean a very long
13529 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
13530 <cached_disp_overlay_modiff>: Cache for last found display string
13532 (compute_display_string_pos): Return the cached position if asked
13533 about the same buffer in the same area of character positions, and
13534 the buffer wasn't changed since the time the display string
13535 position was cached.
13537 2011-07-22 Eli Zaretskii <eliz@gnu.org>
13539 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
13540 is an integer, which is important for empty lines. (Bug#9149)
13542 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
13544 * frame.c (Fmodify_frame_parameters): In tty case, update the
13545 default face if necessary (Bug#4238).
13547 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
13549 * editfns.c (Fstring_to_char): No need to explain what a character
13550 is in the docstring (Bug#6576).
13552 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
13554 * xml.c (parse_region): Make sure we always return a tree.
13556 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
13558 * xml.c (parse_region): If a document contains only comments,
13561 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
13563 * xml.c (make_dom): Return comments, too.
13565 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
13568 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
13569 and the surrounding thread.
13570 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
13571 rather than fgets, and retry after EINTR. Otherwise, 'emacs
13572 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
13574 * s/openbsd.h (BROKEN_SIGIO): Define.
13575 * unexelf.c (unexec) [__OpenBSD__]:
13576 Don't update the .mdebug section of the Alpha COFF symbol table.
13578 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
13580 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
13583 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
13585 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
13586 This fixes some race conditions on the permissions of any newly
13589 * alloc.c (valid_pointer_p): Use pipe, not open.
13590 This fixes some permissions issues when debugging.
13592 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
13593 If fchown fails to set both uid and gid, try to set just gid,
13594 as that is sometimes allowed. Adjust the file's mode to eliminate
13595 setuid or setgid bits that are inappropriate if fchown fails.
13597 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
13599 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
13600 to compare Lisp_Objects.
13601 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to

13605 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
13607 * lread.c (read_integer): Unread even EOF character.
13608 (read1): Likewise. Properly record start position of symbol.
13610 * lread.c (read1): Read `#:' as empty uninterned symbol if no
13611 symbol character follows.
13613 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
13615 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
13616 This works around a problem with the previous change to Fcopy_file.
13617 Recent glibc declares fchown with __attribute__((warn_unused_result)),
13618 and without this change, GCC might complain about discarding
13619 fchown's return value.
13621 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
13623 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
13625 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
13627 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
13629 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
13631 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
13632 it's used from the C level.
13634 * process.c: Use the same condition for POLL_FOR_INPUT in both
13635 keyboard.c and process.c (bug#1858).
13637 2011-07-09 Lawrence Mitchell <wence@gmx.li>
13639 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
13640 (Fgnutls_boot): Use it.
13642 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
13644 * doc.c (Fsubstitute_command_keys): Revert last change.
13646 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
13648 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
13649 quotes the next character, and doesn't affect other longer
13650 sequences (bug#8935).
13652 * lread.c (syms_of_lread): Clarify that is isn't only
13653 `eval-buffer' and `eval-defun' that's affected by
13654 `lexical-binding' (bug#8460).
13656 2011-07-15 Eli Zaretskii <eliz@gnu.org>
13658 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
13659 bidi redisplay when a line includes both an image and is truncated.
13661 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
13663 Fix minor problems found by static checking.
13664 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
13665 (elsz): Now a signed constant, not a size_t var. We prefer signed
13666 types to unsigned, to avoid integer comparison confusion. Without
13667 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
13668 "cannot optimize loop, the loop counter may overflow", a symptom
13670 * indent.c (Fvertical_motion): Mark locals as initialized.
13671 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
13673 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
13675 * search.c (Fre_search_backward): Mention `case-fold-search' in
13676 all the re_search_* functions (bug#8138).
13678 * keyboard.c (Fopen_dribble_file): Document when the file is

13691 bidi_it->string.schars.
13692 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
13693 NULL (avoids a crash in bidi_paragraph_init).
13694 Initialize itb.string.lstring.

13696 buffer position was specified. Initialize paragraph_embedding to
13698 (reseat_to_string): Initialize the bidi iterator.
13699 (display_string): If we need to ignore text properties of
13700 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
13701 original value of -1 will not work with bidi.)
13702 (compute_display_string_pos): First arg is now struct
13703 `text_pos *'; all callers changed. Support display properties on
13705 (compute_display_string_end): Support display properties on Lisp
13707 (init_iterator, reseat_1, reseat_to_string): Initialize the
13708 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
13709 when iterating on a string not from display properties).
13710 (compute_display_string_pos, compute_display_string_end):
13711 Fix calculation of the object to scan. Fixes an error when using
13713 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
13714 base_level_stop; instead, set base_level_stop to BEGV.
13715 Fixes crashes in vertical-motion.
13716 (next_element_from_buffer): Improve commentary for when
13717 the iterator is before prev_stop.
13718 (init_iterator): Initialize bidi_p from the default value of
13719 bidi-display-reordering, not from buffer-local value. Use the
13720 buffer-local value only if initializing for buffer iteration.
13721 (handle_invisible_prop): Support invisible properties on strings
13722 that are being bidi-reordered.
13723 (set_iterator_to_next): Support bidi reordering of C strings and
13725 (next_element_from_string): Support bidi reordering of Lisp

13729 Use IT_STRING_CHARPOS when displaying from a Lisp string.
13730 (init_iterator): Don't initialize it->bidi_p for strings
13732 (reseat_to_string): Initialize it->bidi_p for strings here.
13733 (next_element_from_string, next_element_from_c_string)
13734 (next_element_from_buffer): Add xassert's for correspondence

13739 character that is not the first one in the visual order.
13740 (get_visually_first_element): New function, refactored from common
13741 parts of next_element_from_buffer, next_element_from_string, and
13742 next_element_from_c_string.
13743 (tool_bar_lines_needed, redisplay_tool_bar)
13744 (display_menu_bar): Force left-to-right direction. Add a FIXME
13745 comment for making that be controlled by a user option.
13746 (push_it, pop_it): Save and restore the state of the
13747 bidi iterator. Save and restore the bidi_p flag.
13748 (pop_it): Iterate out of display property for string iteration as
13750 (iterate_out_of_display_property): Support iteration over strings.
13751 (handle_single_display_spec): Set up it->bidi_it for iteration
13752 over a display string, and call bidi_init_it.
13753 (handle_single_display_spec, next_overlay_string)
13754 (get_overlay_strings_1, push_display_prop): Set up the bidi
13755 iterator for displaying display or overlay strings.
13756 (forward_to_next_line_start): Don't use the shortcut if
13758 (back_to_previous_visible_line_start): If handle_display_prop
13759 pushed the iterator stack, restore the internal state of the bidi
13760 iterator by calling bidi_pop_it same number of times.
13761 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
13762 and we are bidi-iterating, don't decrement the iterator position;
13763 instead, set the first_elt flag in the bidi iterator, to produce
13765 (reseat_1): Remove redundant setting of string_from_display_prop_p.
13766 (push_display_prop): xassert that we are iterating a buffer.
13767 (push_it, pop_it): Save and restore paragraph_embedding member.
13768 (handle_single_display_spec, next_overlay_string)
13769 (get_overlay_strings_1, reseat_1, reseat_to_string)
13770 (push_display_prop): Set up the `unibyte' member of bidi_it.string
13771 correctly. Don't assume unibyte strings are not bidi-reordered.
13772 (compute_display_string_pos)
13773 (compute_display_string_end): Fix handling the case of C string.
13774 (push_it, pop_it): Save and restore from_disp_prop_p.

13779 popping after iteration over a string that came from a display
13780 property. Fix a typo in popping stretch info. Add an assertion
13781 for verifying that the iterator position is in sync with the bidi
13783 (handle_single_display_spec, get_overlay_strings_1)
13784 (push_display_prop): Fix initialization of paragraph direction for
13785 string when that of the parent object is not yet determined.

13787 iterator with IT's position. (Bug#7616)
13788 (find_row_edges): If ROW->start.pos gives position
13789 smaller than min_pos, use it as ROW->minpos. (Bug#7616)

13791 Reset the from_disp_prop_p flag.
13792 (SAVE_IT, RESTORE_IT): New macros.

13797 (try_scrolling, redisplay_window, display_line): Use them when
13798 saving a temporary copy of the iterator and restoring it back.
13799 (back_to_previous_visible_line_start, reseat_1)
13800 (init_iterator): Empty the bidi cache "stack".
13801 (move_it_in_display_line_to): If iterator ended up at
13802 EOL, but we never saw any buffer positions smaller than
13803 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
13804 motion in bidi-reordered lines.
13805 (move_it_in_display_line_to): Record prev_method and prev_pos
13806 immediately before the call to set_iterator_to_next. Fixes cursor
13807 motion in bidi-reordered lines with stretch glyphs and strings
13808 displayed in margins. (Bug#8133) (Bug#8867)
13809 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
13811 (pos_visible_p): Support positions in bidi-reordered lines.
13812 Save and restore bidi cache.
13814 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
13815 (bidi_paragraph_info): Delete unused struct.
13816 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
13817 (bidi_cache_start): New variable.
13818 (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not

13832 (bidi_level_of_next_char, bidi_move_to_visually_next):
13833 Support iteration over a string.
13834 (bidi_set_sor_type, bidi_resolve_explicit_1)
13835 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
13836 can now be zero (for strings); special values 0 and -1 were
13837 changed to -1 and -2, respectively.
13838 (bidi_char_at_pos): New function.
13839 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):

13925 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
13927 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
13928 The old code sometimes used this field without initializing it.
13930 * alloc.c (gc_sweep): Don't read past end of array.
13931 In theory, the old code could also have corrupted Emacs internals,
13932 though it'd be very unlikely.

14036 sigprocmask is portable only for single-threaded applications, and
14037 Emacs can be multi-threaded when it uses GTK.

14195 (clone_per_buffer_values): Don't assume that

14197 This isn't true in general, and it's particularly not true
14198 if Emacs is configured with --with-wide-int.
14199 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
14200 New macros, used in the buffer.c change.

14236 Random fixes. E.g., (random) never returned negative values.
14237 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
14238 subseconds part to the entropy, as that's a bit more random.
14239 Prefer signed to unsigned, since the signedness doesn't matter and
14240 in general we prefer signed. When given a limit, use a
14241 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
14242 latter isn't right if USE_2_TAGS_FOR_INTS.
14243 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
14244 not 0..VALMASK. Don't discard "excess" bits that random () returns.

14256 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
14257 This is more efficient than Ffile_directory_p and avoids a minor race.
14259 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
14261 * buffer.c (Foverlay_put): Say what the return value is
14264 * fileio.c (barf_or_query_if_file_exists): Check first if the file
14265 is a directory before asking whether to use the file name
14267 (barf_or_query_if_file_exists): Make the "File is a directory"
14268 error be more correct.
14270 * fns.c (Frequire): Remove the mention of the .gz files, since
14271 that's installation-specific, but keep the mention of

14284 Qgnutls_bootprop_verify_error (which is no longer used).
14286 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
14287 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
14288 Also (re)move comments that are misplaced or no longer relevant.

14317 * lread.c (syms_of_lread): Mention single symbols defined by
14318 `defvar' or `defconst' (bug#7154).
14320 * fns.c (Frequire): Mention .el.gz files (bug#7314).
14321 (Frequire): Mention get-load-suffixes.
14323 2011-07-02 Martin Rudalics <rudalics@gmx.at>

14389 * eval.c (struct backtrace): Simplify and port the data structure.
14390 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
14391 signed bit field, as this assumption is not portable and it makes
14392 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
14393 "char debug_on_exit : 1" as this is not portable either; instead,
14394 use the portable "unsigned int debug_on_exit : 1". Remove unused
14395 member evalargs. Remove obsolete comments about cc bombing out.

14469 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
14470 and use min_width/height from frames size_hint to set
14471 min_width/height (Bug#8919).

14564 (PRINTPREPARE, printchar, strout):
14565 Don't set size unless allocation succeeds.
14567 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
14568 for sizes. Check for string overflow more accurately.

14579 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
14581 * lread.c: Integer overflow fixes.
14582 (read_integer): Radix is now EMACS_INT, not int,
14583 to improve quality of diagnostics for out-of-range radices.
14584 Calculate buffer size correctly for out-of-range radices.
14585 (read1): Check for integer overflow in radices, and in
14586 read-circle numbers.
14587 (read_escape): Avoid int overflow.
14588 (Fload, openp, read_buffer_size, read1)
14589 (substitute_object_recurse, read_vector, read_list, map_obarray):

14610 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
14612 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
14613 The following patches are for when GLYPH_DEBUG && !XASSERT.
14614 * dispextern.h (trace_redisplay_p, dump_glyph_string):
14615 * dispnew.c (flush_stdout):
14616 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
14617 Mark as externally visible.

14630 on undefined behavior with wrong number of arguments.
14631 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
14632 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
14633 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
14634 since we're not interested in debugging glyphs with old libraries.
14635 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
14636 GCC 4.6.0's static checking.
14638 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

14677 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
14678 (x_session_initialize): Do not assume string length fits in int.
14680 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.

14726 Don't assume pid_t and time_t fit in unsigned long.
14727 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
14728 (current_lock_owner): Prefer signed type for sizes.
14729 Use memcpy, not strncpy, where memcpy is what is really wanted.
14730 Don't assume (via atoi) that time_t and pid_t fit in int.
14731 Check for time_t and/or pid_t out of range, e.g., via a network share.
14732 Don't alloca where an auto var works fine.

14761 * lread.c (invalid_syntax): Omit length argument.
14762 All uses changed. This doesn't fix a bug, but it simplifies the
14763 code away from its former Hollerith-constant appearance, and it's
14764 one less 'int' to worry about when looking at integer-overflow issues.
14765 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
14767 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
14768 This didn't break anything, but it didn't help either.
14769 It's confusing to put a bogus integer in a place where the actual
14770 value does not matter.
14771 (LIST_END_P): Remove unused macro and its bogus comment.
14772 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
14774 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
14775 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
14777 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
14778 We prefer signed types, and the value cannot exceed the EMACS_INT
14779 range anyway (because otherwise the length would not be representable).
14780 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
14781 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
14782 This avoids a GCC warning when WIDE_EMACS_INT.
14784 * indent.c (sane_tab_width): New function.
14785 (current_column, scan_for_column, Findent_to, position_indentation)
14786 (compute_motion): Use it. This is just for clarity.
14787 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
14789 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
14791 * lisp.h (lint_assume): New macro.
14792 * composite.c (composition_gstring_put_cache):
14793 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
14795 * editfns.c, insdel.c:
14796 Omit unnecessary forward decls, to simplify future changes.
14798 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
14800 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
14802 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
14803 Use much-faster test for byte-length change.
14804 Don't assume string byte-length fits in 'int'.
14805 Check that character arg fits in 'int'.
14806 (mapcar1): Declare byte as byte, for clarity.
14808 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
14810 * fns.c (concat): Catch string overflow earlier.
14811 Do not rely on integer wraparound.
14813 * dispextern.h (struct it.overlay_strings_charpos)
14814 (struct it.selective): Now EMACS_INT, not int.
14815 * xdisp.c (forward_to_next_line_start)
14816 (back_to_previous_visible_line_start)
14817 (reseat_at_next_visible_line_start, next_element_from_buffer):
14818 Don't arbitrarily truncate the value of 'selective' to int.
14820 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
14822 * composite.c: Don't truncate sizes to 'int'.
14823 (composition_gstring_p, composition_reseat_it)
14824 (composition_adjust_point): Use EMACS_INT, not int.
14825 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
14826 not EMACS_UINT, for indexes.
14828 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
14830 * buffer.c: Include <verify.h>.
14831 (struct sortvec.priority, struct sortstr.priority):
14832 Now EMACS_INT, not int.
14833 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
14834 (struct sortstr.size, record_overlay_string)
14835 (struct sortstrlist.size, struct sortlist.used):
14836 Don't truncate size to int.
14837 (record_overlay_string): Check for size-calculation overflow.
14838 (init_buffer_once): Check at compile-time, not run-time.
14840 2011-06-22 Jim Meyering <meyering@redhat.com>
14842 Don't leak an XBM-image-sized buffer
14843 * image.c (xbm_load): Free the image buffer after using it.
14845 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
14848 * composite.c (find_automatic_composition): Omit needless 'return 0;'
14849 that Sun C diagnosed.
14850 * fns.c (secure_hash): Fix pointer signedness issue.
14851 * intervals.c (static_offset_intervals): New function.
14852 (offset_intervals): Use it.
14854 2011-06-21 Leo Liu <sdl.web@gmail.com>
14857 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
14860 * fns.c (secure_hash): Rename from crypto_hash_function and change
14861 the first arg to accept symbols.
14862 (Fsecure_hash): New primitive.
14863 (syms_of_fns): New symbols.
14865 2011-06-20 Deniz Dogan <deniz@dogan.se>
14867 * process.c (Fset_process_buffer): Clarify return value in
14870 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
14872 * dispnew.c (add_window_display_history): Use BVAR.
14874 * xdisp.c (debug_method_add): Use BVAR.
14875 (check_window_end, dump_glyph_matrix, dump_glyph)
14876 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
14878 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
14881 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
14882 check till after the cache is created in init_frame_faces.
14884 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
14886 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
14888 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
14890 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
14891 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
14892 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
14894 Improve buffer-overflow checking (Bug#8873).
14895 * fileio.c (Finsert_file_contents):
14896 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
14897 Remove the old (too-loose) buffer overflow checks.
14898 They weren't needed, since make_gap checks for buffer overflow.
14899 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
14900 The old code merely checked for Emacs fixnum overflow, and relied
14901 on undefined (wraparound) behavior. The new code avoids undefined
14902 behavior, and also checks for ptrdiff_t and/or size_t overflow.
14904 * editfns.c (Finsert_char): Don't dump core with very negative counts.
14905 Tune. Don't use wider integers than needed. Don't use alloca.
14906 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
14908 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
14910 * insdel.c, lisp.h (buffer_overflow): New function.
14911 (insert_from_buffer_1, replace_range, replace_range_2):
14912 * insdel.c (make_gap_larger):
14913 * editfns.c (Finsert_char):
14914 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
14916 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
14918 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
14920 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
14922 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
14923 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
14925 * fileio.c: Don't assume EMACS_INT fits in off_t.
14926 (emacs_lseek): New static function.
14927 (Finsert_file_contents, Fwrite_region): Use it.
14928 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
14930 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
14932 * fns.c: Don't overflow int when computing a list length.
14933 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
14934 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
14935 truncation on 64-bit hosts. Check for QUIT every
14936 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
14937 faster and is responsive enough.
14938 (Flength): Report an error instead of overflowing an integer.
14939 (Fsafe_length): Return a float if the value is not representable
14940 as a fixnum. This shouldn't happen except in contrived situations.
14941 (Fnthcdr, Fsort): Don't assume list length fits in int.
14942 (Fcopy_sequence): Don't assume vector length fits in int.
14944 * alloc.c: Check that resized vectors' lengths fit in fixnums.
14945 (header_size, word_size): New constants.
14946 (allocate_vectorlike): Don't check size overflow here.
14947 (allocate_vector): Check it here instead, since this is the only
14948 caller of allocate_vectorlike that could cause overflow.
14949 Check that the new vector's length is representable as a fixnum.
14951 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
14952 The previous code was bogus. For example, next_almost_prime (32)
14953 returned 39, which is undesirable as it is a multiple of 3; and
14954 next_almost_prime (24) returned 25, which is a multiple of 5 so
14955 why was the code bothering to check for multiples of 7?
14957 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
14959 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
14961 Variadic C functions now count arguments with ptrdiff_t.
14962 This partly undoes my 2011-03-30 change, which replaced int with size_t.
14963 Back then I didn't know that the Emacs coding style prefers signed int.
14964 Also, in the meantime I found a few more instances where arguments
14965 were being counted with int, which may truncate counts on 64-bit
14966 machines, or EMACS_INT, which may be unnecessarily wide.
14967 * lisp.h (struct Lisp_Subr.function.aMANY)
14968 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
14969 Arg counts are now ptrdiff_t, not size_t.
14970 All variadic functions and their callers changed accordingly.
14971 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
14972 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
14973 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
14974 * callint.c (Fcall_interactively): Check arg count for overflow,
14975 to avoid potential buffer overrun. Use signed char, not 'int',
14976 for 'varies' array, so that we needn't bother to check its size
14977 calculation for overflow.
14978 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
14979 * eval.c (apply_lambda):
14980 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
14981 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
14982 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
14984 * callint.c (Fcall_interactively): Don't use index var as event count.
14986 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
14987 * mem-limits.h (SIZE): Remove; no longer used.
14989 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
14991 Remove unnecessary casts.
14992 * xterm.c (x_term_init):
14993 * xfns.c (x_set_border_pixel):
14994 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
14995 These aren't needed now that we assume ANSI C.
14997 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
14998 It's more likely to cause problems (due to unsigned overflow)
15001 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
15003 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
15005 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
15007 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
15009 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
15011 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
15013 GLYPH_CODE_FACE returns EMACS_INT, not int.
15014 * dispextern.h (merge_faces):
15015 * xfaces.c (merge_faces):
15016 * xdisp.c (get_next_display_element, next_element_from_display_vector):
15017 Don't assume EMACS_INT fits in int.
15019 * character.h (CHAR_VALID_P): Remove unused parameter.
15020 * fontset.c, lisp.h, xdisp.c: All uses changed.
15022 * editfns.c (Ftranslate_region_internal): Omit redundant test.
15024 * fns.c (concat): Minor tuning based on overflow analysis.
15025 This doesn't fix any bugs. Use int to hold character, instead
15026 of constantly refetching from Emacs object. Use XFASTINT, not
15027 XINT, for value known to be a character. Don't bother comparing
15028 a single byte to 0400, as it's always less.
15030 * floatfns.c (Fexpt):
15031 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
15033 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
15036 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
15038 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
15039 Without this fix, on a 64-bit host (aset S 0 4294967386) would
15040 incorrectly succeed when S was a string, because 4294967386 was
15041 truncated before it was used.
15043 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
15044 Otherwise, an out-of-range integer could cause undefined behavior
15047 * composite.c: Use int, not EMACS_INT, for characters.
15048 (fill_gstring_body, composition_compute_stop_pos): Use int, not
15049 EMACS_INT, for values that are known to be in character range.
15050 This doesn't fix any bugs but is the usual style inside Emacs and
15051 may generate better code on 32-bit machines.
15053 Make sure a 64-bit char is never passed to ENCODE_CHAR.
15054 This is for reasons similar to the recent CHAR_STRING fix.
15055 * charset.c (Fencode_char): Check that character arg is actually
15056 a character. Pass an int to ENCODE_CHAR.
15057 * charset.h (ENCODE_CHAR): Verify that the character argument is no
15058 wider than 'int', as a compile-time check to prevent future regressions
15061 * character.c (char_string): Remove unnecessary casts.
15063 Make sure a 64-bit char is never passed to CHAR_STRING.
15064 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
15065 by silently ignoring the top 32 bits, allowing some values
15066 that were far too large to be valid characters.
15067 * character.h: Include <verify.h>.
15068 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
15069 arguments are no wider than unsigned, as a compile-time check
15070 to prevent future regressions in this area.
15072 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
15073 (Fsubst_char_in_region):
15075 * xdisp.c (decode_mode_spec_coding):
15076 Adjust to CHAR_STRING's new requirement.
15077 * editfns.c (Finsert_char, Fsubst_char_in_region):
15078 * fns.c (concat): Check that character args are actually
15079 characters. Without this test, these functions did the wrong
15080 thing with wildly out-of-range values on 64-bit hosts.
15082 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
15083 These casts should not be needed on 32-bit hosts, either.
15084 * keyboard.c (read_char):
15085 * lread.c (Fload): Remove casts to unsigned.
15087 * lisp.h (UNSIGNED_CMP): New macro.
15088 This fixes comparison bugs on 64-bit hosts.
15089 (ASCII_CHAR_P): Use it.
15090 * casefiddle.c (casify_object):
15091 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
15092 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
15093 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
15094 * dispextern.h (FACE_FROM_ID):
15095 * keyboard.c (read_char): Use UNSIGNED_CMP.
15097 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
15098 not to EMACS_INT, to avoid GCC warning.
15100 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
15102 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
15103 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
15104 isn't needed on 32-bit machines.
15106 * buffer.c (Fgenerate_new_buffer_name):
15107 Use EMACS_INT for count, not int.
15108 (advance_to_char_boundary): Return EMACS_INT, not int.
15110 * data.c (Qcompiled_function): Now static.
15112 * window.c (window_body_lines): Now static.
15114 * image.c (gif_load): Rename local to avoid shadowing.
15116 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
15117 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
15118 * alloc.c (make_save_value): Integer argument is now of type
15119 ptrdiff_t, not int.
15120 (mark_object): Use ptrdiff_t, not int.
15121 * lisp.h (pD): New macro.
15122 * print.c (print_object): Use it.
15124 * alloc.c: Use EMACS_INT, not int, to count objects.
15125 (total_conses, total_markers, total_symbols, total_vector_size)
15126 (total_free_conses, total_free_markers, total_free_symbols)
15127 (total_free_floats, total_floats, total_free_intervals)
15128 (total_intervals, total_strings, total_free_strings):
15129 Now EMACS_INT, not int. All uses changed.
15130 (Fgarbage_collect): Compute overall total using a double, so that
15131 integer overflow is less likely to be a problem. Check for overflow
15132 when converting back to an integer.
15133 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
15134 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
15135 These were 'int' variables that could overflow on 64-bit hosts;
15136 they were never used, so remove them instead of repairing them.
15137 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
15138 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
15139 Previously, this ceilinged at INT_MAX, but that doesn't work on
15141 (allocate_pseudovector): Don't use EMACS_INT when int would do.
15143 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
15144 (allocate_vectorlike): Check for ptrdiff_t overflow.
15145 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
15146 when a (possibly-narrower) signed value would do just as well.
15147 We prefer using signed arithmetic, to avoid comparison confusion.
15149 * alloc.c: Catch some string size overflows that we were missing.
15150 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
15151 for convenience in STRING_BYTES_MAX.
15152 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
15153 The definition here is exact; the one in lisp.h was approximate.
15154 (allocate_string_data): Check for string overflow. This catches
15155 some instances we weren't catching before. Also, it catches
15156 size_t overflow on (unusual) hosts where SIZE_MAX <= min
15157 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
15158 and ptrdiff_t and EMACS_INT are both 64 bits.
15160 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
15161 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
15162 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
15164 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
15166 * alloc.c (Fmake_string): Check for out-of-range init.
15168 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
15170 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
15172 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
15174 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
15175 xg_get_default_scrollbar_width.
15177 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
15178 (int_gtk_range_get_value): Move to the scroll bar part of the file.
15179 (style_changed_cb): Call update_theme_scrollbar_width and call
15180 x_set_scroll_bar_default_width and xg_frame_set_char_size for
15181 all frames (Bug#8505).
15182 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
15183 Call gtk_window_set_resizable if HAVE_GTK3.
15184 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
15185 and height if HAVE_GTK3 (Bug#8505).
15186 (scroll_bar_width_for_theme): New variable.
15187 (update_theme_scrollbar_width): New function.
15188 (xg_get_default_scrollbar_width): Move code to
15189 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
15190 (xg_initialize): Call update_theme_scrollbar_width.
15192 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
15194 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
15196 2011-06-12 Martin Rudalics <rudalics@gmx.at>
15198 * frame.c (make_frame): Call other_buffer_safely instead of
15201 * window.c (temp_output_buffer_show): Call display_buffer with
15202 second argument Vtemp_buffer_show_specifiers and reset latter

15654 (Fframe_root_window, Fframe_first_window)
15655 (Fframe_selected_window): Move here from frame.c. Accept frame
15656 or arbitrary window as argument. Update doc-strings.
15657 (Fminibuffer_window): Move up in code.
15658 (Fwindow_minibuffer_p): Move up in code and simplify.
15659 (Fset_frame_selected_window): Move here from frame.c.
15661 (Fselected_window, select_window, Fselect_window): Move up in
15662 code. Minor doc-string fixes.
15664 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
15666 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
15667 Do not assume that spare memory exists; that assumption is valid
15668 only if SYSTEM_MALLOC.
15669 (LARGE_REQUEST): New macro, so that the issue of large requests
15670 is separated from the issue of spare memory.
15672 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
15674 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

15691 2011-06-05 Juanma Barranquero <lekktu@gmail.com>
15693 * xdisp.c (single_display_spec_intangible_p): Remove declaration.
15695 2011-06-04 Chong Yidong <cyd@stupidchicken.com>

15698 (x_clipboard_manager_save): Add return value.
15699 (x_clipboard_manager_error_1, x_clipboard_manager_error_2):
15700 New error handlers.
15701 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
15702 Obey Vx_select_enable_clipboard_manager. Catch errors in
15703 x_clipboard_manager_save (Bug#8779).
15704 (Vx_select_enable_clipboard_manager): New variable.
15705 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
15707 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
15709 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
15711 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15713 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
15714 in the current matrix if keep_current_p is non-zero.

15718 * bidi.c (bidi_level_of_next_char): Fix last change.
15720 2011-06-03 Eli Zaretskii <eliz@gnu.org>
15722 Support bidi reordering of text covered by display properties.
15724 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
15725 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
15726 (bidi_cache_search, bidi_cache_iterator_state)
15727 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
15728 (bidi_level_of_next_char, bidi_move_to_visually_next):
15729 Support character positions inside a run of characters covered by a
15731 (bidi_paragraph_init, bidi_resolve_explicit_1)
15732 (bidi_level_of_next_char): Call bidi_fetch_char and
15733 bidi_fetch_char_advance instead of FETCH_CHAR and
15734 FETCH_CHAR_ADVANCE.
15735 (bidi_init_it): Initialize new members.
15736 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
15738 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
15739 instead of using explicit *_CHAR codes.
15740 (bidi_resolve_explicit, bidi_resolve_weak):
15741 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
15742 bidirectional text is supported only in multibyte buffers.
15743 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
15744 it to initialize the frame_window_p member of struct bidi_it.
15745 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
15746 (bidi_resolve_explicit, bidi_resolve_weak)

15748 bidi_it->nchars is non-positive.
15749 (bidi_level_of_next_char): Don't try to lookup the cache for the
15750 next/previous character if nothing is cached there yet, or if we
15751 were just reseat()'ed to a new position.
15753 * xdisp.c (set_cursor_from_row): Set start and stop points
15754 according to the row's direction when priming the loop that looks
15755 for the glyph on which to display cursor.
15756 (single_display_spec_intangible_p): Function deleted.
15757 (display_prop_intangible_p): Reimplement to call
15758 handle_display_spec instead of single_display_spec_intangible_p.
15759 Accept 3 additional arguments needed by handle_display_spec.
15760 This fixes incorrect cursor motion across display property with complex
15761 values: lists, `(when COND...)' forms, etc.
15762 (single_display_spec_string_p): Support property values that are
15763 lists with the argument STRING its top-level element.
15764 (display_prop_string_p): Fix the condition for processing a
15765 property that is a list to be consistent with handle_display_spec.
15766 (handle_display_spec): New function, refactored from the
15767 last portion of handle_display_prop.
15768 (compute_display_string_pos): Accept additional argument
15769 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
15770 value of a `display' property is a "replacing spec".
15771 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
15772 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
15773 the display property, but just return a value indicating whether
15774 the display property will replace the characters it covers.
15775 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
15776 frame_window_p members of struct bidi_it.
15777 (compute_display_string_pos, compute_display_string_end):
15779 (push_it): Accept second argument POSITION, where pop_it should
15780 jump to continue iteration.
15781 (reseat_1): Initialize bidi_it.disp_pos.
15783 * keyboard.c (adjust_point_for_property): Adjust the call to
15784 display_prop_intangible_p to its new signature.
15786 * dispextern.h (struct bidi_it): New member frame_window_p.
15787 (bidi_init_it): Update prototypes.
15788 (display_prop_intangible_p): Update prototype.
15789 (compute_display_string_pos, compute_display_string_end):
15790 Declare prototypes.
15791 (struct bidi_it): New members nchars and disp_pos. ch_len is now
15794 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
15796 Malloc failure behavior now depends on size of allocation.
15797 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
15798 * lisp.h: Change signatures accordingly.
15799 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
15800 All callers changed. (Bug#8762)
15802 * gnutls.c: Use Emacs's memory allocators.
15803 Without this change, the gnutls library would invoke malloc etc.
15804 directly, which causes problems on non-SYNC_INPUT hosts, and which
15805 runs afoul of improving memory_full behavior. (Bug#8761)
15806 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
15807 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
15808 xfree instead of the default malloc, realloc, free.
15809 (Fgnutls_boot): No need to check for memory allocation failure,
15810 since xmalloc does that for us.
15812 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
15813 * category.c (hash_get_category_set):
15814 * ccl.c (ccl_driver):
15815 * charset.c (Fdefine_charset_internal):
15816 * charset.h (struct charset.hash_index):

15818 (composition_gstring_put_cache):
15819 * composite.h (struct composition.hash_index):
15820 * dispextern.h (struct image.hash):
15821 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
15822 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
15823 (hashfn_equal, hashfn_user_defined, make_hash_table)
15824 (maybe_resize_hash_table, hash_lookup, hash_put)
15825 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
15826 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
15827 (Fsxhash, Fgethash, Fputhash, Fmaphash):
15828 * image.c (make_image, search_image_cache, lookup_image)
15829 (xpm_put_color_table_h):
15830 * lisp.h (struct Lisp_Hash_Table):
15831 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
15832 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
15833 for hashes and hash indexes, instead of 'unsigned' and 'int'.
15834 * alloc.c (allocate_vectorlike):
15835 Check for overflow in vector size calculations.
15836 * ccl.c (ccl_driver):
15837 Check for overflow when converting EMACS_INT to int.
15838 * fns.c, image.c: Remove unnecessary static decls that would otherwise
15839 need to be updated by these changes.
15840 * fns.c (make_hash_table, maybe_resize_hash_table):
15841 Check for integer overflow with large hash tables.
15842 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
15843 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
15844 (SXHASH_REDUCE): New macro.
15845 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
15846 Use it instead of discarding useful hash info with large hash values.
15847 (sxhash_float): New function.
15848 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
15849 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
15850 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
15851 Rewrite to use FIXNUM_BITS, as this simplifies things.
15852 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
15853 Adjust signatures to match updated version of code.
15854 (consing_since_gc): Now EMACS_INT, since a single hash table can
15855 use more than INT_MAX bytes.
15857 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
15859 Make it possible to build with GCC-4.6+ -O2 -flto.
15861 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
15863 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
15865 * minibuf.c (get_minibuffer, read_minibuf_unwind):
15866 Call minibuffer-inactive-mode.
15868 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
15870 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
15871 Update dependencies.
15873 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15875 * data.c (init_data): Remove code for UTS, this system is not
15878 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15880 Don't force ./temacs to start in terminal mode.
15882 * frame.c (make_initial_frame): Initialize faces in all cases, not
15883 only when CANNOT_DUMP is defined.
15884 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
15886 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15888 * dispnew.c (add_window_display_history): Use const for the string
15889 pointer. Remove declaration, not needed.
15891 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
15893 Use 'inline', not 'INLINE'.
15894 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
15895 * alloc.c, fontset.c (INLINE): Remove.
15896 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
15897 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
15898 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
15899 * gmalloc.c (register_heapinfo): Use inline unconditionally.
15900 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
15902 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15904 Make it possible to run ./temacs.
15906 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
15907 syms_of_callproc does the same thing. Remove test for
15908 "initialized", do it in the caller.
15909 * emacs.c (main): Avoid calling set_initial_environment when dumping.
15911 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
15913 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
15914 (read_minibuf): Use get_minibuffer.
15915 (syms_of_minibuf): Use DEFSYM.
15916 (Qmetadata): New var.
15917 * data.c (Qbuffer): Don't make it static.
15918 (syms_of_data): Use DEFSYM.
15920 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
15922 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
15923 (CCL_CODE_MIN): New macro.
15925 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
15927 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
15929 * eval.c (Qdebug): Now static.
15930 * lisp.h (Qdebug): Remove decl. This reverts a part of the
15931 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
15932 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
15934 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
15936 * image.c: Various fixes to ImageMagick code comments.
15937 (Fimagemagick_types): Doc fix.
15939 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
15941 Minor fixes prompted by GCC 4.6.0 warnings.
15943 * xselect.c (converted_selections, conversion_fail_tag): Now static.
15945 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
15946 (x_clipboard_manager_save_all): Move extern decl to ...
15947 * xterm.h: ... here, so that it can be checked for consistency.
15949 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
15951 * xselect.c (x_clipboard_manager_save_frame)
15952 (x_clipboard_manager_save_all): New functions.
15953 (Fx_clipboard_manager_save): Lisp function deleted.
15955 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
15956 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
15958 * xterm.h: Update prototype.
15960 2011-05-28 William Xu <william.xwl@gmail.com>
15962 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
15963 exiting (Bug#8239).
15965 2011-05-28 Jim Meyering <meyering@redhat.com>
15967 Avoid a sign-extension bug in crypto_hash_function.
15968 * fns.c (to_uchar): Define.
15969 (crypto_hash_function): Use it to convert some newly-signed
15970 variables to unsigned, to avoid sign-extension bugs. For example,
15971 without this change, (md5 "truc") would evaluate to
15972 45723a2aff78ff4fff7fff1114760e62 rather than the expected
15973 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
15974 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
15976 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
15978 Integer overflow fixes.
15980 * dbusbind.c: Serial number integer overflow fixes.
15981 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
15982 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
15983 to hold a serial number that is too large for a fixnum.
15984 (Fdbus_method_return_internal, Fdbus_method_error_internal):
15985 Check for serial numbers out of range. Decode any serial number
15986 that was so large that it became a float. (Bug#8722)
15988 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
15989 (Fdbus_call_method, Fdbus_call_method_asynchronously):
15990 Use XFASTINT rather than XUINT when numbers are nonnegative.
15991 (xd_append_arg, Fdbus_method_return_internal):
15992 (Fdbus_method_error_internal): Likewise. Also, for unsigned
15993 arguments, check that Lisp number is nonnegative, rather than
15994 silently wrapping negative numbers around. (Bug#8722)
15995 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
15998 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
16000 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
16002 ccl: Add integer overflow checks.
16003 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
16004 (IN_INT_RANGE): New macros.
16005 (ccl_driver): Use them to check for integer overflow when
16006 decoding a CCL program. Many of the new checks are whether XINT (x)
16007 fits in int; it doesn't always, on 64-bit hosts. The new version
16008 doesn't catch all possible integer overflows, but it's an
16009 improvement. (Bug#8719)
16011 * alloc.c (make_event_array): Use XINT, not XUINT.
16012 There's no need for unsigned here.
16014 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
16015 This follows up to the 2011-05-06 change that substituted uintptr_t
16016 for EMACS_INT. This case wasn't caught back then.
16018 Rework Fformat to avoid integer overflow issues.
16019 * editfns.c: Include <float.h> unconditionally, as it's everywhere
16020 now (part of C89). Include <verify.h>.
16021 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
16022 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
16023 (Fformat): Avoid the prepass trying to compute sizes; it was only
16024 approximate and thus did not catch overflow reliably. Instead, walk
16025 through the format just once, formatting and computing sizes as we go,
16026 checking for integer overflow at every step, and allocating a larger
16027 buffer as needed. Keep track separately whether the format is
16028 multibyte. Keep only the most-recently calculated precision, rather
16029 than them all. Record whether each argument has been converted to
16030 string. Use EMACS_INT, not int, for byte and char and arg counts.
16031 Support field widths and precisions larger than INT_MAX. Avoid
16032 sprintf's undefined behavior with conversion specifications such as %#d
16033 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
16034 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
16035 formatting out-of-range floating point numbers with int
16036 formats. (Bug#8668)
16038 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
16040 * data.c: Avoid integer truncation in expressions involving floats.
16041 * data.c: Include <intprops.h>.
16042 (arith_driver): When there's an integer overflow in an expression
16043 involving floating point, convert the integers to floating point
16044 so that the resulting value does not suffer from catastrophic
16045 integer truncation. For example, on a 64-bit host (* 4
16046 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
16047 Do not rely on undefined behavior after integer overflow.
16049 merge count_size_as_multibyte, parse_str_to_multibyte
16050 * character.c, character.h (count_size_as_multibyte):
16051 Rename from parse_str_to_multibyte; all uses changed.
16052 Check for integer overflow.
16053 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
16054 since it's now a duplicate of the other. This is more of
16055 a character than a buffer op, so better that it's in character.c.
16056 * fns.c, print.c: Adjust to above changes.
16058 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
16060 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
16062 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
16064 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
16065 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
16066 (x_clipboard_manager_save): Now static.
16067 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
16069 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
16070 (crypto_hash_function): Now static.
16071 Fix pointer signedness problems. Avoid unnecessary initializations.
16073 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
16075 * termhooks.h (Vselection_alist): Make it terminal-local.
16077 * terminal.c (create_terminal): Initialize it.
16079 * xselect.c: Support for clipboard managers.
16080 (Vselection_alist): Move to termhooks.h as terminal-local var.
16081 (LOCAL_SELECTION): New macro.
16082 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
16083 (symbol_to_x_atom): Remove gratuitous arg.
16084 (x_handle_selection_request, lisp_data_to_selection_data)
16085 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
16086 (x_own_selection, x_get_local_selection, x_convert_selection):
16087 New arg, specifying work frame. Use terminal-local Vselection_alist.
16088 (some_frame_on_display): Delete unused function.
16089 (Fx_own_selection_internal, Fx_get_selection_internal)
16090 (Fx_disown_selection_internal, Fx_selection_owner_p)
16091 (Fx_selection_exists_p): New optional frame arg.
16092 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
16093 (x_handle_selection_clear): Don't treat other terminals with the
16094 same keyboard specially. Use the terminal-local Vselection_alist.
16095 (x_clear_frame_selections): Use Frun_hook_with_args.
16097 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
16099 * xterm.h: Add support for those atoms.
16101 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
16103 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
16104 (converted_selections, conversion_fail_tag): New global variables.
16105 (x_selection_request_lisp_error): Free the above.
16106 (x_get_local_selection): Remove unnecessary code.
16107 (x_reply_selection_request): Args changed; handle arbitrary array
16108 of converted selections stored in converted_selections.
16109 Separate the XChangeProperty and SelectionNotify steps.
16110 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
16111 (x_convert_selection): New function.
16112 (x_handle_selection_event): Simplify.
16113 (x_get_foreign_selection): Don't ignore incoming requests while
16114 waiting for an answer; this will fail when we implement
16115 SAVE_TARGETS, and seems unnecessary anyway.
16116 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
16117 (Vx_sent_selection_functions): Doc fix.
16119 2011-05-26 Leo Liu <sdl.web@gmail.com>
16121 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
16123 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16125 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
16127 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
16128 for fringe update if it has periodic bitmap.
16129 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
16130 and fringe_bitmap_periodic_p.
16132 * fringe.c (get_fringe_bitmap_data): New function.
16133 (draw_fringe_bitmap_1, update_window_fringes): Use it.
16134 (update_window_fringes): Record periodicity of fringe bitmap in glyph
16135 row. Mark glyph row for fringe update if periodicity changed.
16137 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
16138 for fringe update unless it has periodic bitmap.
16140 2011-05-25 Kenichi Handa <handa@m17n.org>
16142 * xdisp.c (get_next_display_element): Set correct it->face_id for
16143 a static composition.
16145 2011-05-24 Leo Liu <sdl.web@gmail.com>
16148 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
16150 * fns.c (crypto_hash_function, Fsha1): New function.
16151 (Fmd5): Use crypto_hash_function.
16152 (syms_of_fns): Add Ssha1.
16154 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
16156 * gnutls.c: Remove unused macros.
16157 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
16158 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
16159 Remove macros that are defined and never used.
16160 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
16162 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
16164 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
16165 (Fx_get_selection_internal): Minor cleanup.
16166 (Fx_own_selection_internal): Rename arguments for consistency with
16169 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
16171 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
16173 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
16175 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
16177 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16179 * dispnew.c (scrolling_window): Don't exclude the case that the
16180 last enabled row in the desired matrix touches the bottom boundary.
16182 2011-05-21 Glenn Morris <rgm@gnu.org>
16184 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
16185 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
16186 and add some more files.
16188 2011-05-20 Eli Zaretskii <eliz@gnu.org>
16190 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
16191 report_file_error introduced by the change from 2011-05-07.
16193 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
16195 * systime.h (Time): Define only if emacs is defined.
16196 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
16197 where the include path doesn't have X11/X.h by default. See
16198 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
16200 2011-05-20 Kenichi Handa <handa@m17n.org>
16202 * composite.c (find_automatic_composition): Fix previous change.
16204 2011-05-20 Glenn Morris <rgm@gnu.org>
16206 * lisp.mk: New file, split from Makefile.in.
16207 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
16208 (shortlisp): Remove.
16209 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
16211 2011-05-19 Glenn Morris <rgm@gnu.org>
16213 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
16214 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
16215 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
16216 (lisp): Set the order to that of loadup.el.
16217 (shortlisp): Make it a copy of $lisp.
16218 (SOME_MACHINE_LISP): Remove.
16219 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
16220 Use just $shortlisp, not $SOME_MACHINE_LISP too.
16222 2011-05-18 Kenichi Handa <handa@m17n.org>
16224 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
16225 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
16226 (find_automatic_composition): Mostly rewrite for efficiency.
16228 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
16230 * makefile.w32-in: Update dependencies.
16232 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
16234 * menu.c: Include limits.h (fixes the MS-Windows build broken by
16235 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
16237 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
16239 Fix some integer overflow issues, such as string length overflow.
16241 * insdel.c (count_size_as_multibyte): Check for string overflow.
16243 * character.c (lisp_string_width): Check for string overflow.
16244 Use EMACS_INT, not int, for string indexes and lengths; in
16245 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
16246 the resulting string length overflows an EMACS_INT; instead,
16247 report a string overflow if no precision given. When checking for
16248 precision exhaustion, use a check that cannot possibly have
16249 integer overflow. (Bug#8675)
16250 * character.h (lisp_string_width): Adjust to new signature.
16252 * alloc.c (string_overflow): New function.
16253 (Fmake_string): Use it. This doesn't change behavior, but saves
16254 a few bytes and will simplify future changes.
16255 * character.c (string_escape_byte8): Likewise.
16256 * lisp.h (string_overflow): New decl.
16258 Fixups, following up to the user-interface timestamp change.
16259 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
16260 for UI timestamps, instead of unsigned long.
16261 * msdos.c (mouse_get_pos): Likewise.
16262 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
16263 * w32gui.h (Time): Define by including "systime.h" rather than by
16264 declaring it ourselves. (Bug#8664)
16266 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
16267 * image.c (clear_image_cache): Likewise.
16269 * term.c (term_mouse_position): Don't assume time_t wraparound.
16271 Be more systematic about user-interface timestamps.
16272 Before, the code sometimes used 'Time', sometimes 'unsigned long',
16273 and sometimes 'EMACS_UINT', to represent these timestamps.
16274 This change causes it to use 'Time' uniformly, as that's what X uses.
16275 This makes the code easier to follow, and makes it easier to catch
16276 integer overflow bugs such as Bug#8664.
16277 * frame.c (Fmouse_position, Fmouse_pixel_position):
16278 Use Time, not unsigned long, for user-interface timestamps.
16279 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
16280 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
16281 * keyboard.h (last_event_timestamp): Likewise.
16282 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
16283 * menu.h (xmenu_show): Likewise.
16284 * term.c (term_mouse_position): Likewise.
16285 * termhooks.h (struct input_event.timestamp): Likewise.
16286 (struct terminal.mouse_position_hook): Likewise.
16287 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
16288 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
16289 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
16290 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
16291 what it was before.
16292 * menu.h, termhooks.h: Include "systime.h", for Time.
16294 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
16295 Don't assume that the difference between two unsigned long values
16296 can fit into an integer. At this point, we know button_down_time
16297 <= event->timestamp, so the difference must be nonnegative, so
16298 there's no need to cast the result if double-click-time is
16299 nonnegative, as it should be; check that it's nonnegative, just in
16300 case. This bug is triggered when events are more than 2**31 ms
16301 apart (about 25 days). (Bug#8664)
16303 * xselect.c (last_event_timestamp): Remove duplicate decl.
16304 (x_own_selection): Remove needless cast to unsigned long.
16306 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
16307 that always fit in int. Use a sentinel instead of a counter, to
16308 avoid a temp and to allay GCC's concerns about possible int overflow.
16309 * frame.h (struct frame): Use int for menu_bar_items_used
16310 instead of EMACS_INT, since it always fits in int.
16312 * menu.c (grow_menu_items): Check for int overflow.
16314 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
16316 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
16317 Before, the code was not consistent. These values cannot exceed
16318 2**31 - 1 so there's no need to make them unsigned.
16319 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
16320 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
16321 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
16323 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
16325 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
16326 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
16327 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
16328 presumably because the widths might not match.
16330 * window.c (size_window): Avoid needless test at loop start.
16332 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
16334 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
16336 2011-05-12 Drew Adams <drew.adams@oracle.com>
16338 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
16340 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16342 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
16343 `width' to `bar_area_x' and `bar_area_width', respectively.
16344 (x_scroll_run): Take account of fringe background extension.
16346 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
16347 Rename local vars `left' and `width' to `bar_area_x' and
16348 `bar_area_width', respectively.
16349 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
16350 background extension.
16352 2011-05-10 Jim Meyering <meyering@redhat.com>
16354 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
16356 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
16358 * image.c (Finit_image_library): Return t for built-in image types,
16359 like pbm and xbm. (Bug#8640)
16361 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
16363 * w32menu.c (set_frame_menubar): Fix submenu allocation.
16365 2011-05-07 Eli Zaretskii <eliz@gnu.org>
16367 * w32console.c (Fset_screen_color): Doc fix.
16368 (Fget_screen_color): New function.
16369 (syms_of_ntterm): Defsubr it.
16371 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
16372 unlink the temporary file if Fcall_process didn't create it in the
16374 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
16375 child process will be redirected to a file specified with `:file'.
16376 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
16377 cue to call_process_cleanup not to close that handle.
16379 2011-05-07 Ben Key <bkey76@gmail.com>
16381 * makefile.w32-in: The bootstrap-temacs rule now makes use of
16382 one of two shell specific rules, either bootstrap-temacs-CMD or
16383 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
16384 to the previous implementation of the bootstrap-temacs rule.
16385 The bootstrap-temacs-CMD rule is similar to the previous
16386 implementation of the bootstrap-temacs rule except that it
16387 makes use of the ESC_CFLAGS variable instead of the CFLAGS
16390 These changes, along with some changes to nt/configure.bat,
16391 nt/gmake.defs, and nt/nmake.defs, are required to extend my
16392 earlier fix to add support for --cflags and --ldflags options
16393 that include quotes so that it works whether make uses cmd or
16396 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
16398 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
16399 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
16401 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
16402 a string. Handle both cases.
16403 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
16404 (Fdbus_register_method): Use Qinvalid_function.
16406 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
16408 * makefile.w32-in: Update dependencies.
16409 (LISP_H): Add inttypes.h and stdin.h.
16410 (PROCESS_H): Add unistd.h.
16412 2011-05-06 Eli Zaretskii <eliz@gnu.org>
16414 * lread.c: Include limits.h (fixes the MS-Windows build broken by
16415 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
16417 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
16419 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
16421 * term.c (vfatal): Remove stray call to va_end.
16422 It's not needed and the C Standard doesn't allow it here anyway.
16424 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
16425 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
16427 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
16430 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
16432 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16434 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
16436 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
16438 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
16440 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
16441 * charset.c (Fdefine_charset_internal): Don't initialize
16442 charset.code_space[15]. The value was garbage, on hosts with
16443 32-bit int (Bug#8600).
16445 * lread.c (read_integer): Be more consistent with string-to-number.
16446 Use string_to_number to do the actual conversion; this avoids
16447 rounding errors and fixes some other screwups. Without this fix,
16448 for example, #x1fffffffffffffff was misread as -2305843009213693952.
16449 (digit_to_number): Move earlier, for benefit of read_integer.
16450 Return -1 if the digit is out of range for the base, -2 if it is
16451 not a digit in any supported base. (Bug#8602)
16453 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
16455 * dispnew.c (scrolling_window): Return 1 if we scrolled,
16456 to match comment at start of function. This also removes a
16457 GCC warning about overflow in a 32+64-bit port.
16459 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
16461 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
16462 Reported by Stefan Monnier in
16463 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
16464 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
16465 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
16467 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
16468 (EMACS_UINTPTR): Likewise, with uintptr_t.
16470 * lisp.h: Prefer 64-bit EMACS_INT if available.
16471 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
16472 on 32-bit hosts that have 64-bit int, so that they can access
16474 However, temporarily disable this change unless the temporary
16475 symbol WIDE_EMACS_INT is defined.
16477 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
16479 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
16480 This removes an assumption that EMACS_INT and long are the same
16481 width as pointers. The assumption is true for Emacs porting targets
16482 now, but we want to make other targets possible.
16483 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
16484 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
16485 In the rest of the code, change types of integers that hold casted
16486 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
16487 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
16488 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
16489 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
16490 No need to cast type when ORing.
16491 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
16492 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
16493 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
16494 assume EMACS_INT is the same width as char *.
16495 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
16496 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
16497 Remove no-longer-needed casts.
16498 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
16499 (xg_tool_bar_help_callback, xg_make_tool_item):
16500 Use EMACS_INTPTR to hold an integer
16501 that will be cast to void *; this can avoid a GCC warning
16502 if EMACS_INT is not the same width as void *.
16503 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
16504 * xdisp.c (display_echo_area_1, resize_mini_window_1):
16505 (current_message_1, set_message_1):
16506 Use a local to convert to proper width without a cast.
16507 * xmenu.c (dialog_selection_callback): Likewise.
16509 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
16510 Also, don't assume VALBITS / RAND_BITS is less than 5,
16511 and don't rely on undefined behavior when shifting a 1 left into
16513 * lisp.h (get_random): Change signature to match.
16515 * lread.c (hash_string): Use size_t, not int, for hash computation.
16516 Normally we prefer signed values; but hashing is special, because
16517 it's better to use unsigned division on hash table sizes so that
16518 the remainder is nonnegative. Also, size_t is the natural width
16519 for hashing into memory. The previous code used 'int', which doesn't
16520 retain enough info to hash well into very large tables.
16521 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
16523 * dbusbind.c: Don't possibly lose pointer info when converting.
16524 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
16525 Use XPNTR rather than XHASH, so that the high-order bits of
16526 the pointer aren't lost when converting through void *.
16528 * eval.c (Fautoload): Don't double-shift a pointer.
16530 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.

16564 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
16565 Remove unused parameter `fildes'.
16566 * process.c (read_process_output, send_process): Don't pass it.
16568 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
16570 Fix previous change: the library cache is defined in w32.c.
16571 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
16572 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".

16619 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
16621 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
16622 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
16625 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
16627 * xterm.c (x_set_frame_alpha): Do not set property on anything

16664 2011-04-30 Eli Zaretskii <eliz@gnu.org>
16666 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
16667 rather than `XVECTOR (FOO)->size'.
16669 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
16670 inttypes.h, as a gnulib replacement is used if it not available in
16673 2011-04-21 Eli Zaretskii <eliz@gnu.org>
16675 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
16676 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
16677 of MOST_POSITIVE_FIXNUM. (Bug#8528)
16679 * coding.c (coding_alloc_by_realloc): Error out if destination
16680 will grow beyond MOST_POSITIVE_FIXNUM.
16681 (decode_coding_emacs_mule): Abort if there isn't enough place in
16682 charbuf for the composition carryover bytes. Reserve an extra
16683 space for up to 2 characters produced in a loop.

16698 produced by %s or %c overflows available buffer space. (Bug#8545)
16700 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
16702 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

16719 * doprnt.c (doprnt): Don't return value smaller than the buffer
16720 size if the message was truncated. (Bug#8545).
16722 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
16724 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

16733 * makefile.w32-in: Update dependencies.
16735 2011-04-27 Eli Zaretskii <eliz@gnu.org>
16737 Improve `doprnt' and its usage. (Bug#8545)
16738 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
16739 `format_end'. Remove support for %l as a conversion specifier.
16740 Don't use xrealloc. Improve diagnostics when the %l size modifier
16741 is used. Update the commentary.
16743 * eval.c (verror): Simplify calculation of size_t.
16745 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
16748 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
16750 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
16753 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
16755 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
16756 This makes this file independent of the recent pseudovector change.
16758 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
16760 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
16762 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
16763 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
16764 Remove unused local.
16765 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
16767 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
16768 GCC 4.6.0 optimizes based on type-based alias analysis.
16769 For example, if b is of type struct buffer * and v of type struct
16770 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
16771 != &v->size, and therefore "v->size = 1; b->size = 2; return
16772 v->size;" must therefore return 1. This assumption is incorrect
16773 for Emacs, since it type-puns struct Lisp_Vector * with many other
16774 types. To fix this problem, this patch adds a new type struct
16775 vectorlike_header that documents the constraints on layout of vectors
16776 and pseudovectors, and helps optimizing compilers not get fooled
16777 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
16778 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
16779 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
16781 (XSETPVECTYPE): Rewrite in terms of new macro.
16782 (XSETPVECTYPESIZE): New macro, specifying both type and size.
16783 This is a bit clearer, and further avoids the possibility of
16784 undesirable aliasing.
16785 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
16786 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
16787 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
16788 since Lisp_Subr is a special case (no "next" field).
16789 (ASIZE): Now uses header.size rather than size.
16790 All previous uses of XVECTOR (foo)->size replaced to use this macro,
16791 to avoid the hassle of writing XVECTOR (foo)->header.size.
16792 (struct vectorlike_header): New type.
16793 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
16794 object, to help avoid aliasing.
16795 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
16796 (SUBRP): Likewise, since Lisp_Subr is a special case.
16797 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
16798 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
16799 (struct Lisp_Hash_Table): Combine first two members into a single
16800 struct vectorlike_header member. All uses of "size" and "next" members
16801 changed to be "header.size" and "header.next".
16802 * buffer.h (struct buffer): Likewise.
16803 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
16804 * frame.h (struct frame): Likewise.
16805 * process.h (struct Lisp_Process): Likewise.
16806 * termhooks.h (struct terminal): Likewise.
16807 * window.c (struct save_window_data, struct saved_window): Likewise.
16808 * window.h (struct window): Likewise.
16809 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
16810 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
16811 * buffer.c (init_buffer_once): Likewise.
16812 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
16814 * process.c (Fformat_network_address): Use local var for size,
16817 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
16819 Make the Lisp reader and string-to-float more consistent (Bug#8525)
16820 * data.c (atof): Remove decl; no longer used or needed.
16821 (digit_to_number): Move to lread.c.
16822 (Fstring_to_number): Use new string_to_number function, to be
16823 consistent with how the Lisp reader treats infinities and NaNs.
16824 Do not assume that floating-point numbers represent EMACS_INT
16825 without losing information; this is not true on most 64-bit hosts.
16826 Avoid double-rounding errors, by insisting on integers when
16827 parsing non-base-10 numbers, as the documentation specifies.
16828 * lisp.h (string_to_number): New decl, replacing ...
16829 (isfloat_string): Remove.
16830 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
16831 (read1): Do not accept +. and -. as integers; this
16832 appears to have been a coding error. Similarly, do not accept
16833 strings like +-1e0 as floating point numbers. Do not report
16834 overflow for integer overflows unless the base is not 10 which
16835 means we have no simple and reliable way to continue.
16836 Break out the floating-point parsing into a new
16837 function string_to_number, so that Fstring_to_number parses
16838 floating point numbers consistently with the Lisp reader.
16839 (digit_to_number): Move here from data.c. Make it static inline.
16840 (E_CHAR, EXP_INT): Remove, replacing with ...
16841 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
16842 (string_to_number): New function, replacing isfloat_string.
16843 This function checks for valid syntax and produces the resulting
16844 Lisp float number too. Rework it so that string-to-number
16845 no longer mishandles examples like "1.0e+". Use strtoumax,
16846 so that overflow for non-base-10 numbers is reported only when
16847 there's no portable and simple way to convert to floating point.
16849 * textprop.c (set_text_properties_1): Rewrite for clarity,
16850 and to avoid GCC warning about integer overflow.
16852 * intervals.h (struct interval): Use EMACS_INT for members
16853 where EMACS_UINT might cause problems. See
16854 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
16855 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
16856 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
16858 (offset_intervals): Tell GCC not to worry about length overflow
16859 when negating a negative length.
16861 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
16862 (overrun_check_free): Likewise.
16864 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
16865 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
16868 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
16869 (gnutls_make_error): Rename local to avoid shadowing.
16870 (gnutls_emacs_global_deinit): ifdef out; not used.
16871 (Fgnutls_boot): Use const for pointer to readonly storage.
16872 Comment out unused local. Fix pointer signedness problems.
16874 * lread.c (openp): Don't stuff size_t into an 'int'.
16875 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
16876 about possible signed overflow.
16878 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
16879 (GDK_KEY_g): Don't define if already defined.
16880 (xg_prepare_tooltip): Avoid pointer signedness problem.
16881 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
16883 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
16884 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
16886 * xfns.c (Fx_window_property): Simplify a bit,
16887 to make a bit faster and to avoid GCC 4.6.0 warning.
16888 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
16890 * fns.c (internal_equal): Don't assume size_t fits in int.
16892 * alloc.c (compact_small_strings): Tighten assertion a little.
16894 Replace pEd with more-general pI, and fix some printf arg casts.
16895 * lisp.h (pI): New macro, generalizing old pEd macro to other
16896 conversion specifiers. For example, use "...%"pI"d..." rather
16897 than "...%"pEd"...".
16898 (pEd): Remove. All uses replaced with similar uses of pI.
16899 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
16900 * alloc.c (check_pure_size): Don't overflow by converting size to int.
16901 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
16902 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
16903 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
16904 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
16905 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
16907 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
16908 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
16909 * print.c (safe_debug_print, print_object): Likewise.
16910 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
16912 Use pI instead of if-then-else-abort. Use %p to avoid casts,
16913 avoiding the 0 flag, which is not portable.
16914 * process.c (Fmake_network_process): Use pI to avoid cast.
16915 * region-cache.c (pp_cache): Likewise.
16916 * xdisp.c (decode_mode_spec): Likewise.
16917 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
16918 behavior on 64-bit hosts with printf arg.
16919 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
16920 (x_stop_queuing_selection_requests): Likewise.
16921 (x_get_window_property): Don't truncate byte count to an 'int'
16924 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
16925 here, since it parses constructs like leading '-' and spaces,
16926 which are not wanted; and it overflows with large numbers.
16927 Instead, simply match F[0-9]+, which is what is wanted anyway.
16929 * alloc.c: Remove unportable assumptions about struct layout.
16930 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
16931 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
16932 (allocate_vectorlike, make_pure_vector): Use the new macros,
16933 plus offsetof, to remove unportable assumptions about struct layout.
16934 These assumptions hold on all porting targets that I know of, but
16935 they are not guaranteed, they're easy to remove, and removing them
16936 makes further changes easier.
16938 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
16939 This doesn't fix a bug but makes the code clearer.
16940 (string_overrun_cookie): Now const. Use initializers that
16941 don't formally overflow signed char, to avoid warnings.
16942 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
16943 can cause Emacs to crash when string overrun checking is enabled.
16944 (allocate_buffer): Don't assume sizeof (struct buffer) is a
16945 multiple of sizeof (EMACS_INT); it need not be, if
16946 alignof(EMACS_INT) < sizeof (EMACS_INT).
16947 (check_sblock, check_string_bytes, check_string_free_list): Protoize.

16982 * doprnt.c (doprnt): Document the set of format control sequences
16983 supported by the function. Use SAFE_ALLOCA instead of always
16986 * eval.c (verror): Don't limit the buffer size at size_max-1, that
16987 is one byte too soon. Don't use xrealloc; instead xfree and

16999 docstring. Start callback support.
17000 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
17001 unless a fatal error occurred. Call gnutls_alert_send_appropriate

17105 codepoint of an invalid character, to avoid displaying a bogus
17108 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
17109 `error', not SYMBOL_NAME itself.
17111 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
17112 character arguments to `error'.
17114 * charset.c (check_iso_charset_parameter): Fix incorrect argument
17115 to `error' in error message about FINAL_CHAR argument. Make sure
17116 FINAL_CHAR is a character, and use %c when it is passed as
17117 argument to `error'.
17119 2011-04-23 Eli Zaretskii <eliz@gnu.org>
17121 * s/ms-w32.h (localtime): Redirect to sys_localtime.
17123 * w32.c: Include <time.h>.

17187 * dispextern.h (struct redisplay_interface): Rename param
17188 to avoid shadowing.
17189 * termhooks.h (struct terminal): Likewise.

17306 * nsfont.m: Fixed bugs in ns_get_family and
17307 ns_descriptor_to_entity that were caused by using free to
17308 deallocate memory blocks that were allocated by xmalloc (via
17309 xstrdup). This caused Emacs to crash when compiled with
17310 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
17311 --enable-checking=xmallocoverrun). xfree is now used to
17312 deallocate these memory blocks.

17328 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
17329 (emacs_read, emacs_write): Use it.
17330 * process.c (send_process): Adjust to the new signatures of
17331 emacs_write and emacs_gnutls_write. Do not attempt to store
17332 a byte offset into an 'int'; it might overflow.

17810 is outside the buffer's accessible region. (Bug#8468)
17812 2011-04-10 Eli Zaretskii <eliz@gnu.org>
17814 Fix write-region and its subroutines for buffers > 2GB.
17815 * fileio.c (a_write, e_write): Modify declaration of arguments and
17816 local variables to support buffers larger than 2GB.
17817 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
17819 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
17820 argument, local variables, and return value.
17822 * lisp.h: Update prototypes of emacs_write and emacs_read.
17824 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
17826 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
17828 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
17830 Fix more problems found by GCC 4.6.0's static checks.
17832 * xdisp.c (vmessage): Use a better test for character truncation.
17834 * charset.c (load_charset_map): <, not <=, for optimization,
17835 and to avoid potential problems with integer overflow.
17836 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
17837 * casetab.c (set_identity, shuffle): Likewise.
17838 * editfns.c (Fformat): Likewise.
17839 * syntax.c (skip_chars): Likewise.
17841 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
17842 This also lets GCC 4.6.0 generate slightly better loop code.
17844 * callint.c (Fcall_interactively): <, not <=, for optimization.
17845 (Fcall_interactively): Count the number of arguments produced,
17846 not the number of arguments given. This is simpler and lets GCC
17847 4.6.0 generate slightly better code.
17849 * ftfont.c: Distingish more carefully between FcChar8 and char.
17850 The previous code passed unsigned char * to a functions like
17851 strlen and xstrcasecmp that expect char *, which does not
17852 conform to the C standard.
17853 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
17854 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
17855 char * when the C standard requires it.
17857 * keyboard.c (read_char): Remove unused var.
17859 * eval.c: Port to Windows vsnprintf (Bug#8435).
17860 Include <limits.h>.
17861 (SIZE_MAX): Define if the headers do not.
17862 (verror): Do not give up if vsnprintf returns a negative count.
17863 Instead, grow the buffer. This ports to Windows vsnprintf, which
17864 does not conform to C99. Problem reported by Eli Zaretskii.
17865 Also, simplify the allocation scheme, by avoiding the need for
17866 calling realloc, and removing the ALLOCATED variable.
17868 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
17870 Remove invocations of doprnt, as Emacs now uses vsnprintf.
17871 But keep the doprint source code for now, as we might revamp it
17872 and use it again (Bug#8435).
17873 * lisp.h (doprnt): Remove.
17874 * Makefile.in (base_obj): Remove doprnt.o.
17875 * deps.mk (doprnt.o): Remove.
17877 error: Print 32- and 64-bit integers portably (Bug#8435).
17878 Without this change, on typical 64-bit hosts error ("...%d...", N)
17879 was used to print both 32- and 64-bit integers N, which relied on
17880 undefined behavior.
17881 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
17882 * lisp.h (error, verror): Mark as printf-like functions.
17883 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
17884 Report overflow in size calculations when allocating printf buffer.
17885 Do not truncate output string at its first null byte.
17886 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
17887 Truncate the output at a character boundary, since vsnprintf does not
17889 * charset.c (check_iso_charset_parameter): Convert internal
17890 character to string before calling 'error', since %c now has the
17892 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
17893 overflow when computing char to be passed to 'error'. Do not
17894 pass Lisp_Object to 'error'; pass the integer instead.
17895 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
17896 formatted with plain %d.
17898 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
17900 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
17902 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
17904 * xterm.c (x_catch_errors): Remove duplicate declaration.
17906 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
17908 * xdisp.c, lisp.h (message_nolog): Remove; unused.
17910 2011-04-10 Jim Meyering <meyering@redhat.com>
17912 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
17913 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
17914 return ssize_t not "int", and use size_t as the buffer length.
17915 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
17916 * gnutls.h: Update declarations.
17917 * process.c (read_process_output): Use ssize_t, to match.
17918 (send_process): Likewise.
17920 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
17922 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
17924 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
17926 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
17927 Use unsigned char, to match FcChar8 type definition.
17929 * xterm.c (handle_one_xevent):
17930 * xmenu.c (create_and_show_popup_menu):
17931 * xselect.c (x_decline_selection_request)
17932 (x_reply_selection_request): Avoid type-punned deref of X events.
17934 2011-04-09 Eli Zaretskii <eliz@gnu.org>
17936 Fix some uses of `int' instead of EMACS_INT.
17937 * search.c (string_match_1, fast_string_match)
17938 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
17939 (scan_buffer, find_next_newline_no_quit)
17940 (find_before_next_newline, search_command, Freplace_match)
17941 (Fmatch_data): Make some `int' variables be EMACS_INT.
17943 * xdisp.c (display_count_lines): 3rd argument and return value now
17944 EMACS_INT. All callers changed.
17945 (pint2hrstr): Last argument is now EMACS_INT.
17947 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
17948 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
17949 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
17950 (decode_coding_utf_16, decode_coding_emacs_mule)
17951 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
17952 (decode_coding_ccl, decode_coding_charset)
17953 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
17954 (decode_coding_iso_2022, decode_coding_emacs_mule)
17955 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
17956 <char_offset, last_offset>: Declare EMACS_INT.
17957 (encode_coding_utf_8, encode_coding_utf_16)
17958 (encode_coding_emacs_mule, encode_invocation_designation)
17959 (encode_designation_at_bol, encode_coding_iso_2022)
17960 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
17961 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
17963 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
17964 (encode_invocation_designation): Last argument P_NCHARS is now
17966 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
17967 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
17969 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
17972 * ccl.c (Fccl_execute_on_string): Declare some variables
17975 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
17977 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
17979 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
17981 * process.c (Fformat_network_address): Doc fix.
17983 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
17985 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
17987 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
17989 * keyboard.c (read_char): Call Lisp function help-form-show,
17990 instead of using internal_with_output_to_temp_buffer.
17991 (Qhelp_form_show): New var.
17992 (syms_of_keyboard): Use DEFSYM macro.
17994 * print.c (internal_with_output_to_temp_buffer): Function deleted.
17996 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
17998 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
18000 * process.c (Flist_processes): Remove to Lisp.
18001 (list_processes_1): Delete.

18005 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
18007 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
18009 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
18011 Fix more problems found by GCC 4.6.0's static checks.
18013 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
18015 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
18017 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
18019 * xdisp.c (vmessage): Mark as a printf-like function.
18021 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
18023 * sound.c (sound_warning): Don't crash if arg contains a printf format.
18025 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
18026 printf-like functions.

18028 to system-supplied API.
18030 * eval.c (Fsignal): Remove excess argument to 'fatal'.
18032 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
18033 This avoids several warnings with gcc -Wstrict-overflow.
18034 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
18035 directly, rather than having caller test rule sign. This avoids
18036 some unnecessary tests.
18037 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
18038 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
18039 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
18041 * xfont.c (xfont_text_extents): Remove var that was set but not used.
18042 (xfont_open): Avoid unnecessary tests.
18044 * composite.c (composition_gstring_put_cache): Use unsigned integer.
18046 * composite.h, composite.c (composition_gstring_put_cache):
18047 Use EMACS_INT, not int, for length.

18050 breaking out part of COMPOSITION_DECODE_RULE.
18051 (COMPOSITION_DECODE_RULE): Use it.
18052 * composite.c (get_composition_id): Remove unused local vars,
18053 by using the new macro.
18055 * textprop.c (set_text_properties_1): Change while to do-while,
18056 since the condition is always true at first.
18058 * intervals.c (graft_intervals_into_buffer): Mark var as used.
18059 (interval_deletion_adjustment): Return unsigned value.
18062 * process.c (list_processes_1, create_pty, read_process_output):

18072 (update_syntax_table): Use unsigned instead of int.
18074 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
18075 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
18076 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
18078 * print.c (print_error_message): Avoid int overflow.
18080 * font.c (font_list_entities): Redo for clarity,
18081 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
18083 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
18084 (font_score): Avoid potential overflow in diff calculation.
18086 * fns.c (substring_both): Remove var that is set but not used.
18087 (sxhash): Redo loop for clarity and to avoid wraparound warning.
18089 * eval.c (funcall_lambda): Rename local to avoid shadowing.
18091 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
18092 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
18093 can always succeed if overflow has undefined behavior.
18095 * search.c (boyer_moore, wordify): Remove vars set but not used.
18096 (wordify): Omit three unnecessary tests.
18098 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
18099 All callers changed. This avoids the need for an unused var.
18101 * casefiddle.c (casify_region): Remove var that is set but not used.
18103 * dired.c (file_name_completion): Remove var that is set but not used.
18105 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
18107 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
18108 (Finsert_file_contents): Remove unnecessary code checking fd.
18110 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
18111 Check for integer overflow on size calculations.
18113 * buffer.c (Fprevious_overlay_change): Remove var that is set
18116 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
18117 Remove vars that are set but not used.
18118 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
18119 (timer_check_2): Mark vars as initialized.
18121 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
18123 * image.c (lookup_image): Remove var that is set but not used.
18124 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
18126 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
18127 that are set but not used.
18129 * xfns.c (make_invisible_cursor): Don't return garbage
18130 if XCreateBitmapFromData fails (Bug#8410).
18132 * xselect.c (x_get_local_selection, x_handle_property_notify):
18133 Remove vars that are set but not used.
18135 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

18145 (map_tty_color) [!defined MSDOS]: Likewise.
18147 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
18149 * coding.c: Remove vars that are set but not used.
18150 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
18151 All callers changed.

18153 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
18154 (decode_coding_charset): Remove vars that are set but not used.
18156 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
18157 that is set but not used.
18159 * print.c (print_object): Remove var that is set but not used.
18161 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
18162 The gnulib version avoids calling malloc in the usual case,
18163 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
18164 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
18165 * filelock.c (current_lock_owner): Likewise.
18166 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.

18169 (emacs_readlink): New function.
18170 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
18171 ../lib/careadlinkat.h.
18173 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
18175 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
18176 first non-nil return value).

18190 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
18191 and thereabouts. All callers changed.
18192 (get_per_char_metric): Remove parameter `f', unused since
18193 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

18197 do not dereference NULL upon failed strdup
18198 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
18199 (ns_get_family): Likewise.
18201 2011-04-02 Juanma Barranquero <lekktu@gmail.com>

18275 (try_scrolling): Use it when setting scroll_limit.
18276 Limit scrolling to 100 screen lines.
18277 (redisplay_window): Even when falling back on "recentering",
18278 position point in the window according to scroll-conservatively,
18279 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
18281 (try_scrolling): When point is above the window, allow searching
18282 as far as scroll_max, or one screenful, to compute vertical
18283 distance from PT to the scroll margin position. This prevents
18284 try_scrolling from unnecessarily failing when
18285 scroll-conservatively is set to a value slightly larger than the
18286 window height. Clean up the case of PT below the margin at bottom
18287 of window: scroll_max can no longer be INT_MAX. When aggressive
18288 scrolling is in use, don't let point enter the opposite scroll
18289 margin as result of the scroll.
18290 (syms_of_xdisp) <scroll-conservatively>: Document the
18291 threshold of 100 lines for never-recentering scrolling.
18293 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
18295 * dispextern.h (move_it_by_lines):
18296 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
18297 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
18298 (message_log_check_duplicate): Remove parameters `prev_bol' and
18299 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
18300 (redisplay_internal): Remove parameter `preserve_echo_area',
18301 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
18303 * indent.c (Fvertical_motion):
18304 * window.c (window_scroll_pixel_based, Frecenter):
18305 Don't pass `need_y_p' to `move_it_by_lines'.
18307 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
18309 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
18310 steal a few bits to be more compact.
18311 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
18312 Remove unneeded casts.
18314 * bytecode.c (Fbyte_code): CAR and CDR can GC.
18316 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
18318 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
18319 binding" message (bug#7967).
18321 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
18323 Fix more problems found by GCC 4.6.0's static checks.
18325 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
18326 Remove unused local var.
18328 * editfns.c (Fmessage_box): Remove unused local var.
18330 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
18331 (note_mode_line_or_margin_highlight, note_mouse_highlight):
18332 Omit unused local vars.
18333 * window.c (shrink_windows): Omit unused local var.
18334 * menu.c (digest_single_submenu): Omit unused local var.
18335 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
18336 Omit unused local var.
18338 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
18339 Don't assume string length fits in int.
18340 (keyremap_step, read_key_sequence): Use size_t for sizes.
18341 (read_key_sequence): Don't check last_real_key_start redundantly.
18343 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
18344 instead of alloca (Bug#8344).
18346 * eval.c (Fbacktrace): Don't assume nargs fits in int.
18347 (Fbacktrace_frame): Don't assume nframes fits in int.
18349 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
18351 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
18354 * term.c (produce_glyphless_glyph): Remove unnecessary test.
18356 * cm.c (calccost): Turn while-do into do-while, for clarity.
18358 * keyboard.c (syms_of_keyboard): Use the same style as later
18359 in this function when indexing through an array. This also
18360 works around GCC bug 48267.
18362 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
18364 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
18366 * chartab.c (sub_char_table_ref_and_range): Redo for slight
18367 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
18369 * keyboard.c, keyboard.h (num_input_events): Now size_t.
18370 This avoids undefined behavior on integer overflow, and is a bit
18371 more convenient anyway since it is compared to a size_t variable.
18373 Variadic C functions now count arguments with size_t, not int.
18374 This avoids an unnecessary limitation on 64-bit machines, which
18375 caused (substring ...) to crash on large vectors (Bug#8344).
18376 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
18377 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

18381 * editfns.c (general_insert_function): Likewise.
18382 * eval.c (struct backtrace.nargs, interactive_p)
18383 (internal_condition_case_n, run_hook_with_args, apply_lambda)
18384 (funcall_lambda, mark_backtrace): Likewise.
18385 * fns.c (concat): Likewise.
18386 * frame.c (x_set_frame_parameters): Likewise.
18387 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
18388 0 if not found, not -1. All callers changed.
18390 * alloc.c (garbage_collect): Don't assume stack size fits in int.
18391 (stack_copy_size): Now size_t, not int.
18392 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
18394 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
18396 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
18397 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
18398 All callers changed.
18400 * lisp.h (multibyte_char_to_unibyte):
18401 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
18402 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
18403 * character.h (CHAR_TO_BYTE8):
18404 * cmds.c (internal_self_insert):
18405 * editfns.c (general_insert_function):
18406 * keymap.c (push_key_description):
18407 * search.c (Freplace_match):
18408 * xdisp.c (message_dolog, set_message_1): All callers changed.
18410 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
18412 * keyboard.c (safe_run_hook_funcall): New function.
18413 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
18414 don't set the hook to nil, but remove the offending function instead.
18415 (Qcommand_hook_internal): Remove, unused.
18416 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
18417 Vcommand_hook_internal.
18419 * eval.c (enum run_hooks_condition): Remove.
18420 (funcall_nil, funcall_not): New functions.
18421 (run_hook_with_args): Call each function through a `funcall' argument.
18422 Remove `cond' argument, now redundant.
18423 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
18424 (Frun_hook_with_args_until_failure): Adjust accordingly.
18425 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
18427 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
18429 * dispextern.h (string_buffer_position): Remove declaration.
18431 * print.c (strout): Remove parameter `multibyte', unused since
18432 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
18434 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
18435 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
18436 All callers changed.
18438 * w32.c (_wsa_errlist): Use braces for struct initializers.
18440 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
18441 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
18442 All callers changed.
18443 (string_buffer_position): Likewise. Also, make static (it's never
18444 used outside xdisp.c).
18445 (cursor_row_p): Remove parameter `w', unused since
18446 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

18448 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
18449 All callers changed.
18451 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
18453 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

18459 (ns_update_auto_hide_menu_bar): New functions.
18460 (ns_update_begin): Call ns_update_auto_hide_menu_bar.

18463 (constrainFrameRect): Return at once if ns_menu_bar_should_be_hidden.
18464 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
18466 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
18468 * nsmenu.m (runDialogAt): Remove argument to timer_check.
18470 2011-03-27 Glenn Morris <rgm@gnu.org>
18472 * syssignal.h: Replace RETSIGTYPE with void.
18473 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
18474 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
18475 Replace SIGTYPE with void everywhere.
18476 * s/usg5-4-common.h (SIGTYPE): Remove definition.
18477 * s/template.h (SIGTYPE): Remove commented out definition.
18479 2011-03-26 Eli Zaretskii <eliz@gnu.org>
18481 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
18482 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
18484 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
18486 * w32.c (read_unc_volume): Use parameter `henum', instead of
18487 global variable `wget_enum_handle'.
18489 * keymap.c (describe_vector): Remove parameters `indices' and
18490 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

18493 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
18495 * keyboard.c (timer_check): Remove parameter `do_it_now',
18496 unused since 1996-04-12T06:01:29Z!rms@gnu.org.
18497 (show_help_echo): Remove parameter `ok_to_overwrite_keystroke_echo',
18498 unused since 2008-04-19T19:30:53Z!monnier@iro.umontreal.ca.
18500 * keyboard.c (read_char):
18501 * w32menu.c (w32_menu_display_help):
18502 * xmenu.c (show_help_event, menu_help_callback):
18503 Adjust calls to `show_help_echo'.
18505 * gtkutil.c (xg_maybe_add_timer):
18506 * keyboard.c (readable_events):
18507 * process.c (wait_reading_process_output):
18508 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
18510 * insdel.c (adjust_markers_gap_motion):
18511 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.

18561 Don't pass uninitialized region to CombineRgn.
18563 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
18565 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.
18566 (w32_wnd_proc): Pass NULL to Windows API, not uninitialized buffer.
18567 (Fx_close_connection): Remove unused variable `i'.

18585 2011-03-23 Julien Danjou <julien@danjou.info>
18587 * term.c (Fsuspend_tty, Fresume_tty):
18588 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
18589 * window.c (temp_output_buffer_show):
18590 * insdel.c (signal_before_change):
18591 * frame.c (Fhandle_switch_frame):
18592 * fileio.c (Fdo_auto_save):
18593 * emacs.c (Fkill_emacs):
18594 * editfns.c (save_excursion_restore):
18595 * cmds.c (internal_self_insert):
18596 * callint.c (Fcall_interactively):
18597 * buffer.c (Fkill_all_local_variables):
18598 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
18600 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
18601 unconditionally since it does the check itself.
18603 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
18605 Fix more problems found by GCC 4.5.2's static checks.
18607 * coding.c (encode_coding_raw_text): Avoid unnecessary test
18608 the first time through the loop, since we know p0 < p1 then.
18609 This also avoids a gcc -Wstrict-overflow warning.
18611 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
18612 leading to a memory leak, possible in functions like
18613 load_charset_map_from_file that can allocate an unbounded number
18614 of objects (Bug#8318).
18616 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
18617 that could (at least in theory) be that large.
18619 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
18620 This is less likely to overflow, and avoids undefined behavior if
18621 overflow does occur. All callers changed. Use strtoul to scan
18622 for the unsigned long integer.
18623 (pint2hrstr): Simplify and tune code slightly.
18624 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
18626 * scroll.c (do_scrolling): Work around GCC bug 48228.
18627 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
18629 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
18630 This also avoids a warning with gcc -Wstrict-overflow.
18631 (validate_x_resource_name): Simplify count usage.
18632 This also avoids a warning with gcc -Wstrict-overflow.
18634 * fileio.c (Fcopy_file): Report error if fchown or fchmod
18637 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
18639 * process.c (Fmake_network_process): Use socklen_t, not int,
18640 where POSIX says socklen_t is required in portable programs.
18641 This fixes a porting bug on hosts like 64-bit HP-UX, where
18642 socklen_t is wider than int (Bug#8277).
18643 (Fmake_network_process, server_accept_connection):
18644 (wait_reading_process_output, read_process_output):
18647 * process.c: Rename or move locals to avoid shadowing.
18648 (list_processes_1, Fmake_network_process):
18649 (read_process_output_error_handler, exec_sentinel_error_handler):
18650 Rename or move locals.
18651 (Fmake_network_process): Define label "retry_connect" only if needed.
18652 (Fnetwork_interface_info): Fix pointer signedness.
18653 (process_send_signal): Add cast to avoid pointer signedness problem.
18654 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
18655 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
18657 Make tparam.h and terminfo.c consistent.
18658 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
18659 Include tparam.h instead, since it declares them.
18660 * cm.h (PC): Remove extern decl; tparam.h now does this.
18661 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
18662 * terminfo.c: Include tparam.h, to check interfaces.
18663 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
18664 (tparam): Adjust signature to match interface in tparam.h;
18665 this removes some undefined behavior. Check that outstring and len
18666 are zero, which they always are with Emacs.
18667 * tparam.h (PC, BC, UP): New extern decls.
18669 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
18670 (xftfont_open): Rename locals to avoid shadowing.
18672 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
18673 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
18674 (OTF_TAG_SYM): Omit macro if not needed.
18675 (ftfont_list): Remove unused local.
18676 (get_adstyle_property, ftfont_pattern_entity):
18677 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
18678 Rename locals to avoid shadowing.
18680 * xfont.c (xfont_list_family): Mark var as initialized.
18682 * xml.c (make_dom): Now static.
18684 * composite.c (composition_compute_stop_pos): Rename local to
18686 (composition_reseat_it): Remove unused locals.
18687 (find_automatic_composition, composition_adjust_point): Likewise.
18688 (composition_update_it): Mark var as initialized.
18689 (find_automatic_composition): Mark vars as initialized,
18690 with a FIXME (Bug#8290).
18692 character.h: Rename locals to avoid shadowing.
18693 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
18694 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
18695 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
18696 (BUF_DEC_POS): Be more systematic about renaming local temporaries
18697 to avoid shadowing.
18699 * textprop.c (property_change_between_p): Remove; unused.

18716 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
18718 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
18719 clobbering (Bug#8298).
18720 * sysdep.c (sys_subshell): Likewise.
18721 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
18723 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
18724 This should get cleaned up, so that child_setup has the
18725 same signature on all platforms.
18727 * callproc.c (call_process_cleanup): Now static.
18728 (relocate_fd): Rename locals to avoid shadowing.
18730 2011-03-22 Chong Yidong <cyd@stupidchicken.com>

18858 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
18859 some of which prompt warnings from gcc -Wbad-function-cast.
18860 (Fformat_time_string, Fencode_time, Finsert_char):

18889 (Fmemory_limit): Cast sbrk's returned value to char *.
18891 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

18894 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
18896 Use functions, not macros, for up- and down-casing (Bug#8254).
18897 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
18898 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
18899 to use the following functions instead of these macros.
18900 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
18901 EMACS_INT, since callers assume the returned value fits in int.
18902 (upcase1): Likewise, for UPCASE_TABLE.
18903 (uppercasep, lowercasep, upcase): New static inline functions.
18904 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

18914 (regex_compile, re_match_2_internal): Mark locals as initialized.
18915 (RETALLOC_IF): Define only if needed.
18916 (WORDCHAR_P): Likewise. This one is never needed, but is used
18917 only in a comment talking about a compiler bug, so put inside
18918 the #if 0 of that comment.
18919 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
18920 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

18946 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
18947 New macros, so that the caller can use some names other than
18948 gcpro1, gcpro2, etc.
18949 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
18951 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
18952 argument, for consistency with GCPRO2_VAR, etc: it is now the
18953 prefix of the variable, not the variable itself. All uses
18955 * dired.c (directory_files_internal, file_name_completion):
18956 Rename locals to avoid shadowing.
18958 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
18959 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
18960 dired.c's scmp function, had undefined behavior.
18961 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
18962 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
18963 * buffer.h: ... to here, because these macros use current_buffer,
18964 and the new implementation with inline functions needs to have
18965 current_buffer in scope now, rather than later when the macros
18967 (downcase, upcase1): New static inline functions.
18968 (DOWNCASE, UPCASE1): Reimplement using these functions.
18969 This avoids undefined behavior in expressions like
18970 DOWNCASE (x) == DOWNCASE (y), which previously suffered
18971 from race conditions in accessing the global variables
18972 case_temp1 and case_temp2.
18973 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
18974 * lisp.h (case_temp1, case_temp2): Remove their decls.
18975 * character.h (ASCII_CHAR_P): Move from here ...
18976 * lisp.h: ... to here, so that the inline functions mentioned
18977 above can use them.
18979 * dired.c (directory_files_internal_unwind): Now static.
18981 * fileio.c (file_name_as_directory, directory_file_name):
18982 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
18984 (file_name_as_directory): Use const pointers when appropriate.
18985 (Fexpand_file_name): Likewise. In particular, newdir might
18986 point at constant storage, so make it a const pointer.
18987 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
18988 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
18990 (Fset_file_times, Finsert_file_contents, auto_save_error):
18991 Rename locals to avoid shadowing.

18995 to avoid shadowing.
18997 * marker.c (bytepos_to_charpos): Remove; unused.
18999 * lisp.h (verify_bytepos, count_markers): New decls,
19000 so that gcc does not warn that these functions aren't declared.
19002 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
19003 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
19004 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
19005 (copy_text): Remove unused local var.
19007 * filelock.c (within_one_second): Now static.
19008 (lock_file_1): Rename local to avoid shadowing.
19010 * buffer.c (fix_overlays_before): Mark locals as initialized.
19011 (fix_start_end_in_overlays): Likewise. This function should be
19012 simplified by using pointers-to-pointers, but that's a different
19014 (switch_to_buffer_1): Now static.
19015 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
19016 (report_overlay_modification): Rename locals to avoid shadowing.
19018 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
19019 Fix pointer signedness issue.
19020 (sys_subshell): Mark local as volatile if checking for lint,
19021 to suppress a gcc -Wclobbered warning that does not seem to be right.
19022 (MAXPATHLEN): Define only if needed.
19024 * process.c (serial_open, serial_configure): Move decls from here ...
19025 * systty.h: ... to here, so that they can be checked.
19027 * fns.c (get_random, seed_random): Move extern decls from here ...
19028 * lisp.h: ... to here, so that they can be checked.
19030 * sysdep.c (reset_io): Now static.
19031 (wait_for_termination_signal): Remove; unused.
19033 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
19034 (copy_keymap_item, append_key, push_text_char_description):
19036 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
19037 (DENSE_TABLE_SIZE): Remove; unused.
19038 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
19039 (describe_map_tree):
19040 Rename locals to avoid shadowing.
19042 * keyboard.c: Declare functions static if they are not used elsewhere.

19127 (BUF_PT_BYTE): Rewrite to handle indirect buffers (Bug#8219).
19128 These macros can no longer be used for assignment.
