5 2012-12-14 Eli Zaretskii <eliz@gnu.org>
7 * w32.c (get_name_and_id): Always pass NULL as the first argument
8 of lookup_account_sid. Avoids crashes with UNC file names that
9 refer to DFS domains, not to specific machine names. (Bug#12621)
10 Remove now unused argument FNAME; all callers changed.
11 (get_file_owner_and_group): Remove now unused argument FNAME; all
14 2012-12-11 Eli Zaretskii <eliz@gnu.org>
16 * search.c (search_buffer): Check the inverse translations of each
17 character in pattern when the buffer being searched is unibyte.
20 2012-12-10 Paul Eggert <eggert@cs.ucla.edu>
22 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
23 files, fixing a regression from 24.2.
24 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
26 2012-12-08 Jan Djärv <jan.h.d@swipnet.se>
28 * nsterm.m (fd_handler:): FD_ZERO fds (Bug#13103).
30 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
32 * w32fns.c (cache_system_info): Cast sysinfo_cache.dwPageSize to
33 DWORD_PTR, for compatibility with 64-bit builds.
35 * w32.c (_PROCESS_MEMORY_COUNTERS_EX):
36 (GetProcessWorkingSetSize_Proc, get_process_working_set_size)
37 (system_process_attributes): Use SIZE_T rather than DWORD, for
38 compatibility with 64-bit builds.
40 2012-12-08 Christopher Schmidt <christopher@ch.ristopher.com>

44 2012-12-07 Eli Zaretskii <eliz@gnu.org>
46 * indent.c (Fvertical_motion): If a display string will be
47 displayed on the left or the right margin, don't consider it as a
48 factor in cursor positioning. (Bug#13108)
50 2012-12-07 Martin Rudalics <rudalics@gmx.at>
52 * editfns.c (Fcompare_buffer_substrings): Reword doc-string.
54 2012-12-05 Eli Zaretskii <eliz@gnu.org>
56 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
57 fails, signal an error instead of continuing with an empty
59 Encode expanded temp file pattern before passing it to mkstemp or
62 2012-12-04 Eli Zaretskii <eliz@gnu.org>
64 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
65 Encode the file name before passing it to dostounix_filename, in
66 case it will downcase it (under w32-downcase-file-names).
69 2012-12-01 Chong Yidong <cyd@gnu.org>
71 * fileio.c (Vauto_save_list_file_name): Doc fix.
73 2012-11-30 Fabrice Popineau <fabrice.popineau@gmail.com>
75 * w32fns.c: Remove prototype of atof.
76 (syspage_mask): Declared DWORD_PTR, for compatibility with 64-bit
78 (file_dialog_callback): Declared UINT_PTR.
80 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
83 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
84 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already

91 2012-11-26 Eli Zaretskii <eliz@gnu.org>
93 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
96 2012-11-24 Paul Eggert <eggert@cs.ucla.edu>
98 Revert recent change for Bug#8855.
99 As reported by Harald Hanche-Olsen in
100 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00445.html>
101 the change introduces a further bug, of creating lots of zombie
102 processes in some cases. Further work is needed to come up with a
103 better fix for Bug#8855.
105 2012-11-24 Eli Zaretskii <eliz@gnu.org>
107 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
108 highlighting on the frame was cleared. Prevents assertion
109 violations when repeatedly clicking on the "Top" link of the
110 "bread-crumbs" in Info buffers.
112 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
113 Eli Zaretskii <eliz@gnu.org>
115 Fix a race condition with glib (Bug#8855).
116 The symptom is a diagnostic "GLib-WARNING **: In call to
117 g_spawn_sync(), exit status of a child process was requested but
118 SIGCHLD action was set to SIG_IGN and ECHILD was received by
119 waitpid(), so exit status can't be returned." The diagnostic
120 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
121 The real bug is a race condition between Emacs and glib: Emacs
122 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
123 so that glib can't find it. Work around the bug by invoking
124 waitpid only on subprocesses that Emacs itself creates.
126 This is a backport from the trunk, consisting of:
128 * w32proc.c (create_child): Don't clip the PID of the child
129 process to fit into an Emacs integer, as this is no longer a
131 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
132 reaping only the process specified by PID argument, if that is
133 positive. Use PID instead of dead_child to know which process to
134 reap. Wait for the child to die only if WNOHANG is not in
136 (sys_select): Don't set dead_child.
138 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
139 as it is no longer needed.
141 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
143 (create_process, record_child_status_change): Don't use special
144 value -1 in pid field, as the caller now must know the pid rather
145 than having the callee infer it. The inference was sometimes
146 incorrect anyway, due to another race.
147 (create_process): Set new 'alive' member if child is created.
148 (process_status_retrieved): New function.
149 (record_child_status_change): Use it.
150 Accept negative 1st argument, which means to wait for the
151 processes that Emacs already knows about. Move special-case code
152 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
153 processes that have already been waited for, by testing and
154 clearing new 'alive' member. Remove the setting of
155 record_at_most_one_child for the !WNOHANG case.
156 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
157 now does this internally.
158 (handle_child_signal): Let record_child_status_change do all
159 the work, since we do not want to reap all exited child processes,
160 only the child processes that Emacs itself created.
161 * process.h (Lisp_Process): New boolean member 'alive'.
163 2012-11-23 Eli Zaretskii <eliz@gnu.org>
165 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
166 between bpos_covered and bpos_max. This fixes cursor display when
167 several display strings follow each other.
169 * .gdbinit (pgx): If the glyph's object is a string, display the
170 pointer to string data, rather than the value of the string object
171 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
173 2012-11-21 Eli Zaretskii <eliz@gnu.org>
175 * indent.c (Fvertical_motion): If the starting position is covered
176 by a display string, return to one position before that, to avoid
177 overshooting it inside move_it_to. (Bug#12930)
179 2012-11-20 Daniel Colascione <dancol@dancol.org>
181 * w32fns.c (Fx_file_dialog):
182 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
183 cygwin_convert_file_name*.
185 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
186 Rename cygwin_convert_path* to cygwin_convert_file_name*.
188 2012-11-20 Ken Brown <kbrown@cornell.edu>
190 * emacs.c (main): Set the G_SLICE environment variable for all
191 Cygwin builds, not just GTK builds. See
192 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
194 2012-11-19 Eli Zaretskii <eliz@gnu.org>
196 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Don't mix declaration of
197 w32_note_current_window with code. (Backport from trunk.)
199 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
200 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
201 Define for the MSVC compiler.
203 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing
206 2012-11-18 Eli Zaretskii <eliz@gnu.org>
208 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
209 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
210 dostounix_filename. Prevents crashes down the road, because
211 dostounix_filename assumes it gets a unibyte string. Reported by
212 Michel de Ruiter <michel@sentient.nl>, see
213 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
215 2012-11-17 Eli Zaretskii <eliz@gnu.org>
217 * w32select.c: Include w32common.h before w32term.h, so that
218 windows.h gets included before w32term.h uses some of its
221 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]: New
223 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]: New
225 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
227 2012-11-17 Jan Djärv <jan.h.d@swipnet.se>
229 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
230 (ns_select): Return at once if events are held (Bug#12834).
232 2012-11-16 enami tsugutomo <tsugutomo.enami@jp.sony.com>
234 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
235 Needed following 2012-10-20 change. (Bug#12902)
237 2012-11-16 Glenn Morris <rgm@gnu.org>
239 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
241 2012-11-15 Stefan Monnier <monnier@iro.umontreal.ca>
243 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
245 2012-11-14 Eli Zaretskii <eliz@gnu.org>
247 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
248 use the same value of thread handle.
249 (start_timer_thread): If the timer thread exited (due to error),
250 clean up by closing the two handles it used. Duplicate the caller
251 thread's handle here, so it gets duplicated only once, when
252 launching the timer thread. Set priority of the timer thread, not
254 (getitimer): Don't duplicate the caller thread's handle here.
257 2012-11-13 Jan Djärv <jan.h.d@swipnet.se>
259 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
262 2012-11-12 Eli Zaretskii <eliz@gnu.org>
264 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
265 passed to pint2str and pint2hrstr to be at most the size of the
266 frame's decode_mode_spec_buffer. This avoids crashes with very
267 large values of FIELD_WIDTH argument to decode_mode_spec.
270 2012-11-07 Martin Rudalics <rudalics@gmx.at>
272 * window.c (Fsplit_window_internal): Set combination limit of
273 new parent window to t iff Vwindow_combination_limit is t;
274 fixing a regression introduced with the change from 2012-09-22.
275 (Fwindow_combination_limit, Fset_window_combination_limit):
278 2012-11-06 Eli Zaretskii <eliz@gnu.org>
280 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
281 amount when the scroll margins are too large. When scrolling
282 backwards in the buffer, give up if cannot reach point or the
283 scroll margin within a reasonable number of screen lines.
284 Fixes point position in window under scroll-up/down-aggressively when
285 point is positioned many lines beyond the window top/bottom.
288 2012-11-05 Eli Zaretskii <eliz@gnu.org>
290 * ralloc.c (relinquish): If real_morecore fails to return memory
291 to the system, don't crash; instead, leave the last heap
292 unchanged and return. (Bug#12774)
294 2012-11-03 Eli Zaretskii <eliz@gnu.org>
296 * lisp.mk: Adjust comments to the fact that term/internal is now
297 loaded from loadup.el.
299 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
300 (msdos_fatal_signal): New function.
301 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
304 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
305 for GCC versions before 4.
306 (emacs_raise): Define to call msdos_fatal_signal.
308 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
309 iterator when starting in the middle of a display or overlay
312 2012-11-03 Jan Djärv <jan.h.d@swipnet.se>
314 * widget.c (resize_cb): New function.
315 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
316 (EmacsFrameResize): Check if all is up to date before changing frame
319 2012-11-01 Eli Zaretskii <eliz@gnu.org>
321 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
323 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
325 Fix crash when using Emacs as commit editor for git (Bug#12697).
326 * callproc.c (setpgrp): Remove macro, as we now use setpgid
327 and it is configured in conf_post.h.
328 (Fcall_process): Don't invoke both setsid and setpgid; the former
329 is enough, if it exists.
330 * callproc.c (Fcall_process, child_setup):
331 * process.c (create_process): Use setpgid.
332 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
334 * dispnew.c (init_display): Initialize the foreground group
335 if we are running a tty display.
336 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
337 * lisp.h (init_foreground_group): New decl.
338 * sysdep.c (inherited_pgroup): New static var.
339 (init_foreground_group, tcsetpgrp_without_stopping)
340 (narrow_foreground_group, widen_foreground_group): New functions.
341 (init_sys_modes): Narrow foreground group.
342 (reset_sys_modes): Widen foreground group.
344 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
346 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
348 2012-10-31 Martin Rudalics <rudalics@gmx.at>
350 * minibuf.c (read_minibuf): Restore current buffer since
351 choose_minibuf_frame calling Fset_frame_selected_window may
352 change it (Bug#12766).
354 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
356 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
358 2012-10-30 Kenichi Handa <handa@gnu.org>
360 * font.c (Ffont_at): If WINDOW is specified and it is not
361 displaying the current buffer, signal an error.
363 2012-10-29 Daniel Colascione <dancol@dancol.org>
365 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
366 In preparation for fixing bug#12739, move these functions from
369 * coding.h, coding.c: ... to here, and compile them only when
370 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
371 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
373 2012-10-28 Eli Zaretskii <eliz@gnu.org>
375 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
376 (timer_loop, getitimer, setitimer): Use it instead of
377 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
379 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
382 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
384 * nsterm.m (NO_APPDEFINED_DATA): New define.
385 (last_appdefined_event_data): New variable
386 (last_appdefined_event): Remove.
387 (ns_select): Initialize t from last_appdefined_event_data instead
388 of [last_appdefined_event data1].
389 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
390 remove last_appdefined_event (Bug#12698).
392 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
394 * frame.c (x_set_font): Catch internal error.
396 2012-10-27 Eli Zaretskii <eliz@gnu.org>
398 Avoid overflow in w32 implementation of interval timers.
399 When possible, for ITIMER_PROF count only times the main thread
401 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
402 'volatile ULONGLONG' types. All the other data which was
403 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
404 (GetThreadTimes_Proc): New typedef.
405 (w32_get_timer_time): New function, returns a suitable time value
407 (timer_loop): Enter critical section when accessing ULONGLONG
408 values of the itimer_data struct, as these accesses are no longer
409 atomic. Call 'w32_get_timer_time' instead of 'clock'.
410 Remove unused variable.
411 (init_timers): Initialize s_pfn_Get_Thread_Times.
412 (start_timer_thread): Don't assign itimer->caller_thread here.
413 (getitimer): Assign itimer->caller_thread here.
414 (setitimer): Always call getitimer to get the value of ticks_now.
415 (sys_spawnve): Avoid compiler warning about format mismatch.
417 2012-10-26 Eli Zaretskii <eliz@gnu.org>
419 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
420 mouse movement events if the menu bar is active. This avoids
421 producing a busy "hour-glass" cursor by Windows if the mouse
422 pointer is positioned over a tooltip shown for some menu item.
424 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
426 Don't assume process IDs fit in int.
427 * emacs.c (shut_down_emacs) [!DOS_NT]:
428 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
429 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
430 Use pid_t, not int, to store process IDs, as 'int'
431 is not wide enough on a few platforms (e.g., AIX and IRIX).
433 2012-10-23 Kenichi Handa <handa@gnu.org>
435 The following change is to make face-font-rescale-alist work
436 correctly for non-ASCII fonts.
438 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
439 (font_open_for_lface): Handle Vface_font_rescale_alist.
441 2012-10-23 Chong Yidong <cyd@gnu.org>
443 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
445 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
447 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
449 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
451 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
454 2012-10-21 Glenn Morris <rgm@gnu.org>
456 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
458 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
461 * frame.c (Fmouse_position, Fmouse_pixel_position):
462 * xdisp.c (produce_stretch_glyph):
463 Declare local vars only when they're needed.
464 This is clearer and avoids a warning on OpenBSD about unused vars.
465 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
466 This is safer, and avoids OpenBSD warnings about unused vars.
467 * keyboard.c (record_menu_key): Remove unnecessary decl.
468 (poll_timer): Define only if POLL_FOR_INPUT is defined.
469 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
470 as our definition clashes with OpenBSD's.
471 * xfaces.c (load_face_colors, check_lface_attrs)
472 (get_lface_attributes_no_remap, get_lface_attributes)
473 (lface_fully_specified_p, x_supports_face_attributes_p)
474 (tty_supports_face_attributes_p, face_fontset, realize_face)
475 (realize_x_face, realize_tty_face):
476 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
477 merely Lisp_Object *. This is more informative and avoids
478 a warning on OpenBSD about accessing beyond an object's size.
480 2012-10-20 Chong Yidong <cyd@gnu.org>
482 * lread.c (Fload): Doc fix (Bug#12592).
484 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
486 * font.c (Ffont_at): Fix previous change.
488 2012-10-19 Eli Zaretskii <eliz@gnu.org>
490 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
491 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
494 * alloc.c (NSTATICS): Decrease to 0x800.
496 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>
498 * fns.c (Fnreverse): Include the problem element when signalling an
501 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
503 * nsterm.m (ns_select): Check writefds before call to
504 FD_ISSET (Bug#12668).
506 2012-10-18 Daniel Colascione <dancol@dancol.org>
508 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
509 (staticpro): If we run out of staticpro slots, die with an
510 informative error instead of just calling emacs_abort.
512 2012-10-18 Martin Rudalics <rudalics@gmx.at>
514 Fix two flaws reported by Dmitry Antipov.
515 * window.c (Ftemp_output_buffer_show): Remove.
516 (Fwindow_vscroll, Fset_window_vscroll): Use decode_live_window.

765 * keyboard.c (timers_run, swallow_events)
766 (detect_input_pending_run_timers):
767 * process.c (wait_reading_process_output):
768 Use unsigned for counter where wraparound-on-overflow is desired,
769 since unsigned is guaranteed to have that behavior and signed is not.
770 (read_char): Use ptrdiff_t for string length.
771 (get_input_pending): Remove first argument, since it was always
772 the same pointer-to-int (now pointer-to-boolean) &input_pending,
773 and behave as if it had that value. Return new value of
774 input_pending. All callers changed.
775 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
776 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's

797 * termopts.h (flow_control, meta_key): Remove unused decls.
798 * dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c:
799 Don't include termopts.h.
801 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>

816 2012-10-09 Eli Zaretskii <eliz@gnu.org>
818 * w32fns.c (w32_last_error): Change the return value to DWORD, to
819 match what GetLastError returns. Explain why the function is
822 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
823 'is_tooltip_frame', to avoid confusion with its global namesake.
825 2012-10-08 Daniel Colascione <dancol@dancol.org>
827 * xdisp.c (start_hourglass): Call w32_note_current_window when
828 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
829 build that caused Emacs to display the hourglass cursor forever.
831 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
832 which is broken under remote desktop, calculate the number of
833 colors available for a display based on the display's number of
834 planes and number of bits per pixel per plane. (bug#10397).
836 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
838 * nsfont.m (Vfonts_in_cache): New variable.
839 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
840 are used. Add cached fonts to Vfonts_in_cache.
841 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
843 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
845 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
847 (FONT_H): Define after FRAME_H.
848 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
851 * w32term.c: Remove leftover declaration of keyboard_codepage.
853 2012-10-08 Eli Zaretskii <eliz@gnu.org>
855 * makefile.w32-in (FONT_H): Add $(FRAME_H).
856 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
857 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
858 (GLOBAL_SOURCES): Add cygw32.c.
859 ($(BLD)/unexw32.$(O)):
861 ($(BLD)/w32console.$(O)):
862 ($(BLD)/w32fns.$(O)):
863 ($(BLD)/w32heap.$(O)):
864 ($(BLD)/w32menu.$(O)):
865 ($(BLD)/w32proc.$(O)): Add w32common.h.
867 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
869 (x_to_w32_color): Don't modify the argument, modify a copy instead.
871 2012-10-08 Daniel Colascione <dancol@dancol.org>
873 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
874 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
875 accidental message numbering hole. Change other messages to
878 * w32select.h (HAVE_W32SELECT): Remove.

881 w32common.h instead of w32heap.h.

885 (get_w32_minor_version, sysinfo_cache, osinfo_cache)

891 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
892 (w32_minor_version, w32_build_number, w32_subtype):
893 Remove duplicate definitions.
895 * w32fns.c: Include w32common.h; include w32heap.h only in
898 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
899 Use `report_file_error' instead of `error' in order to better
900 inform users of what went wrong. Increase NTGUI_UNICODE file
901 dialog box file name length to 32k, the maximum allowed by the NT
904 * w32common.h: New file.
905 (ROUND_UP, ROUND_DOWN, get_page_size)
906 (get_allocation_unit, get_processor_type, get_w32_major_version)
907 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
908 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
909 (OS_NT, os_subtype, cache_system_info): Move here.
911 * unexw32.c, unexcw.c: Include w32common.h.
913 * emacs.c (main): Use (defined (WINDOWSNT) || defined
914 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
915 to call syms_of_w32select.
917 * cygw32.h: Remove obsolete EXFUN declarations.
919 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
921 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
922 of w32inevt.o from SOME_MACHINE_OBJECTS.
924 2012-10-08 Daniel Colascione <dancol@dancol.org>
926 * image.c: Permanent fix for JPEG compilation issue --- limit
927 jpeglib `boolean' redefinition to Cygwin builds.
929 2012-10-08 Eli Zaretskii <eliz@gnu.org>
931 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
933 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
936 2012-10-08 Daniel Colascione <dancol@dancol.org>
938 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
939 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
940 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,

942 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
943 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
944 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
945 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
946 now a supported configuration.
948 * Makefile.in: consolidate image variables into LIBIMAGE; add
949 W32_OBJ and W32_LIBS. Compile new files.
952 (_DebPrint) declare tracing facility for W32 debugging. We need
953 to unify tracing later.
955 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
956 unconditional use of W32 Unicode functions. Cygwin runs only on
957 100% Unicode operating systems.
959 * cygw32.c: New file. Define Cygwin-specific facilities.
960 (Fcygwin_convert_path_to_windows)
961 (Fcygwin_convert_path_from_windows): New user functions for
962 accessing Cygwin path-munging routines.
964 * cygw32.h: New file.
965 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
966 UTF-16LE strings temporarily inside non-Lisp-visible string
969 (w32_strerror): Just what it says on the tin.
971 * emacs.c: Make the NS fork-then-exec code for daemon-launching
972 also run for Cygwin; both systems have the same problem with using
973 GUI facilities in a forked child. Also call syms_of_cygw32,
974 syms_of_w32select in correct places.
976 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
977 needs fork-then-exec for daemon launching.
979 * font.h: Include frame.h.
981 * image.c: Use the image library cache machinery only when we're
982 compiling for native WINDOWSNT; Cygwin can use shared libraries
983 like any other Unixlike system.
985 * keyboard.c: Clarify a comment regarding the input loop.
987 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
988 functions directly instead of trying to detect at runtime that our
989 host operating system supports them. We make this change for two
990 reasons: Cygwin lacks support for the multibyte character
991 conversion functions used by the legacy menu code, and Cygwin
992 never needs to rely on non-Unicode APIs.
994 * unexw32.c (hinst): Declare extern.
996 * w32.c: Change header order;
997 (w32_strerror): Move to w32fns.c because we need it for
998 non-WINDOWSNT builds.
1000 * w32.h: Add #error macro to make sure we don't include w32.h for
1001 Cygwin builds. Remove w32select declarations.
1003 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
1004 w32fns.c. w32console.c is WINDOWSNT-only.
1006 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
1007 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
1009 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
1010 (w32_major_version, w32_minor_version, w32_build_number)
1011 (os_subtype, sound_type): Define here
1012 (w32_defined_color): Make color parameter const for consistency
1013 with other _defined_color functions.
1014 (w32_createwindow): Unconditionally call w32_init_class instead of
1015 doing so only when hprevinst is non-NULL. Plumbing hprevinst
1016 through the code is complex and unnecessary because class
1017 registration is practically free.
1018 (w32_name_of_message): New EMACSDEBUG-only function.
1019 (Fset_message_beep): Move here
1020 (Fx_open_connection): Require that the display name for Windows be
1021 "w32" for consistency, emacsclient disambiguation, and maybe, one
1022 day, multi-window-system support.
1023 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
1024 Cygwin files for W32 GUI facilities, since these clearly don't
1025 expect Cygwin names.
1026 (_DebPrint): Define.
1027 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
1028 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
1029 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
1030 (w32_last_error): Remove.

1038 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
1039 (w32_console_toggle_lock_key): Move to w32fns.c.
1041 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
1043 * w32proc.c (_DebPrint): Move to w32fns.c.
1044 * w32select.c: Include string.h, stdio.h for Cygwin.
1045 * w32select.h: New File.
1047 * w32term.c: Include io.h for non-CYGWIN builds; needed for
1049 (w32_message_fd): New variable. Under Cygwin, holds the file
1050 descriptor the system used to tell us about pending thread
1053 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
1054 that prevented compilation under non-WINDOWSNT systems.
1056 (w32_initialize): Open /dev/windows and assign it to
1057 w32_message_fd. Provide w32 feature.
1059 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
1060 (WM_EMACS_INPUT_READY): add.
1061 (prepend_msg, w32_message_fd): Declare globally.
1064 (keyboard_handle): Use only when WINDOWSNT.
1065 (notify_msg_ready): New function. Posts a message to the main
1066 thread's message queue under CYGWIN, which wakes up the main
1067 thread from select(2) by making the /dev/windows file descriptor
1068 ready. Under WINDOWSNT, it sets an event the same way the old
1071 (post, prepend_msg): Actually call notify_msg_ready instead of
1072 setting the input event directly.
1074 2012-10-07 Eli Zaretskii <eliz@gnu.org>
1076 * ralloc.c (relinquish): If a heap is ready to be relinquished,
1077 but it still has blocs in it, don't return it to the system,
1078 instead of aborting. (Bug#12402)
1080 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
1082 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).

1113 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
1115 Improve sys_siglist detection.
1116 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
1117 defined as a macro, as is done in Solaris.
1118 (sys_siglist_entries): New macro.
1119 (save_strsignal): Use it.
1120 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
1121 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
1123 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
1125 * nsfns.m (Fx_create_frame): Call x_default_parameter with
1126 fullscreen/Fullscreen.
1128 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
1129 tobar_height is new.
1131 * nsterm.m (x_make_frame_visible): Check for fullscreen.
1132 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
1133 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.

1142 (canBecomeMainWindow): New function.
1144 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
1146 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
1148 2012-10-05 Eli Zaretskii <eliz@gnu.org>
1150 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
1152 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
1153 that time stamps of directories could also be changed.
1154 Don't request the too broad GENERIC_WRITE, only the more restrictive
1155 FILE_WRITE_ATTRIBUTES access rights.
1157 * fileio.c (Fset_file_times): Special-case ignoring errors for
1158 directories only on MSDOS, not on MS-Windows.
1160 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
1162 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
1164 2012-10-04 Eli Zaretskii <eliz@gnu.org>
1166 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
1167 see whether CreateFile failed.
1169 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
1171 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
1172 to avoid similar races.
1173 * keyboard.c (pending_signals): Now bool, not int.
1175 Port timers to OpenBSD, plus check for timer failures.
1176 OpenBSD problem reported by Han Boetes.
1177 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
1179 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
1180 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
1181 like OpenBSD, which has timer_settime but does not declare it.
1182 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
1183 whether to use itimerspec-related primitives. All uses of
1184 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
1186 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
1188 * profiler.c (handle_profiler_signal): Fix a malloc race
1189 that caused Emacs to hang on Fedora 17 when profiling Lisp.
1191 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
1193 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
1195 2012-10-02 Eli Zaretskii <eliz@gnu.org>
1197 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
1198 consistent with the change in return value of 'safe_strsignal'.
1200 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
1202 Prefer plain 'static' to 'static inline' (Bug#12541).
1203 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
1204 (bidi_set_sor_type, bidi_push_embedding_level)
1205 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
1206 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)

1210 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
1211 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
1212 Now 'static', not 'static inline'.
1214 Count overruns when profiling; change units to ns.
1215 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
1216 Give extra weight to samples after overruns, to attempt to count
1217 the time more accurately.
1218 (setup_cpu_timer): Change sampling interval units from ms to ns, since
1219 the underlying primitives nominally do ns.
1220 (Fprofiler_cpu_start): Document the change. Mention that
1221 the sampling intervals are only approximate.
1223 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
1225 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
1227 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
1228 case for the special 0 coding-system.
1230 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
1231 (Fmake_overlay): Remove redundant tests.
1232 (fix_start_end_in_overlays): Remove redundant recentering.
1234 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
1236 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
1237 Update dependencies.
1239 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
1241 Fix a malloc race condition involving strsignal.
1242 A signal can arrive in the middle of a malloc, and Emacs's signal
1243 handler can invoke strsignal, which can invoke malloc, which is
1244 not portable. This race condition bug makes Emacs hang on GNU/Linux.
1245 Fix it by altering the signal handler so that it does not invoke
1247 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
1248 * process.c (status_message): Use const pointer, in case strsignal
1249 is #defined to safe_strsignal.
1250 * sysdep.c (sys_siglist, init_signals): Always define and
1251 initialize a substitute sys_siglist if the system does not define
1252 one, even if HAVE_STRSIGNAL.
1253 (safe_strsignal): Rename from strsignal. Always define,
1254 using sys_siglist. Return a const pointer.
1255 * syssignal.h (safe_strsignal): New decl.
1256 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
1258 2012-10-01 Eli Zaretskii <eliz@gnu.org>
1260 * w32proc.c (timer_loop): Fix code that waits for timer
1261 expiration, to avoid high CPU usage.
1263 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
1265 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
1266 (sweep_weak_table): Remove redundant prototypes.
1268 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
1270 * emacs.c: Move the inclusion of TERM_HEADER after including
1271 windows.h on WINDOWSNT. This avoids compilation problems with
1274 2012-10-01 Eli Zaretskii <eliz@gnu.org>
1276 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
1277 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
1278 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
1279 as the previous version used 'void *'.
1281 * ralloc.c (ROUNDUP): Fix last change.
1282 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
1285 * w32proc.c <disable_itimers>: New static flag.
1286 (init_timers): Initialize it to zero, after creating the critical
1287 sections used by the timer threads.
1288 (term_timers): Set to 1 before deleting the critical sections.
1289 (getitimer, setitimer): If disable_itimers is non-zero, return an
1290 error indication without doing anything. Reported by Fabrice
1291 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
1292 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
1294 [!HAVE_SETITIMER]: Behave as the previous version that didn't
1297 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
1298 term_ntproc after all the other bookkeeping, to get timers working
1299 as long as possible.
1301 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
1303 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
1304 Suggested by Juri Linkov in
1305 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
1307 Prefer plain 'static' to 'static inline' (Bug#12541).
1308 With static functions, modern compilers inline pretty well by
1309 themselves; advice from programmers often hurts as much as it helps.
1310 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
1311 this change shrinks the text size of the Emacs executable by 1.1%
1312 without affecting CPU significantly in my benchmark.
1313 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)
1314 (live_float_p, live_misc_p, live_vector_p, live_buffer_p)

1388 (x_set_glyph_string_clipping, x_clear_glyph_string_rect):
1389 Now 'static', not 'static inline'.
1392 (bidi_copy_it): Do the whole copy with a single memcpy.
1393 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
1395 Revert the FOLLOW-SYMLINKS change for file-attributes.
1396 Doing it right would require several changes to Tramp, and there's
1397 not enough time to get that tested before the freeze today.
1398 * dired.c (directory_files_internal, Ffile_attributes):
1401 * frame.c (x_report_frame_params): Port better to wider ints.
1402 Do not assume that EMACS_UINT is the same width as uprintmax_t,
1403 or that pointers can be printed in 15 decimal digits.
1404 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

1585 Suggested by Eli Zaretskii in
1586 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
1588 2012-09-30 Eli Zaretskii <eliz@gnu.org>
1590 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
1591 HAVE_TIMER_SETTIME is defined.
1593 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
1595 Profiler improvements: more-accurate timers, overflow checks.
1596 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
1597 signal.h, setjmp.h. Include systime.h instead.
1598 (saturated_add): New function.

1605 All uses changed to store the new value.
1606 (handle_profiler_signal): Rename from sigprof_handler_1,
1607 for consistency with other handlers. Do not check whether
1608 cpu_log is a hash-table if garbage collecting, since it
1609 doesn't matter in that case.

1611 for consistency with other handlers.
1612 (setup_cpu_timer): New function, with much of what used to be in
1613 Fprofiler_cpu_start. Check for out-of-range argument.
1614 Prefer timer_settime if available, and prefer
1615 thread cputime clocks, then process cputime clocks, then
1616 monotonic clocks, to the old realtime clock. Use make_timeval
1617 to round more-correctly when falling back to setitimer.
1618 (Fprofiler_cpu_start): Use it.
1619 (Fprofiler_cpu_stop): Prefer timer_settime if available.
1620 Don't assume that passing NULL as the 2nd argument of setitimer

1623 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
1624 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
1625 non-fatal signal handlers. Ignore SIGPROF on startup.
1626 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
1627 in profiler.c, since sysdep.c now uses it.
1629 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

1685 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
1686 Since this stuff is now private to charset.c, there's no need for
1687 a public macro and no need to inline by hand.

1761 (sys_kill): Improve commentary.
1763 * w32.c (term_ntproc): Accept (and ignore) one argument, for
1764 consistency with a signature of a signal handler. All callers
1766 (init_ntproc): Accept an argument DUMPING. If dumping, don't
1767 install term_ntproc as a signal handler for SIGABRT, as that
1768 should be done by the dumped Emacs.
1770 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
1772 * w32select.c (term_w32select): Protect against repeated
1773 invocation by setting clipboard_owner to NULL after calling

1900 * w32term.c (w32_read_socket): Remove leftover reference to
1901 interrupt_input_pending.
1903 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
1905 Do not use SA_NODEFER.
1906 Problem reported by Dani Moncayo in
1907 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
1909 * sysdep.c (emacs_abort): Do not reset signal handler.
1910 * emacs.c (terminate_due_to_signal): Reset signal handler here.
1911 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
1912 wanted even on POSIXish hosts, and it doesn't work on Windows.
1914 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
1916 * xterm.c (x_term_init): Call fixup_locale before and after calling
1917 gtk_init (Bug#12392).
1919 2012-09-23 Chong Yidong <cyd@gnu.org>
1921 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
1922 Vdynamic_library_alist.
1924 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
1925 (Fgnutls_available_p): Caller changed.
1927 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
1928 (Flibxml_parse_xml_region): Likewise.
1930 * dispextern.h (struct image_type): Remove arg from init function.
1932 * image.c (Finit_image_library, lookup_image_type)
1933 (define_image_type): Remove now-unneeded second arg.
1934 (init_xpm_functions, init_png_functions, init_jpeg_functions)
1935 (init_tiff_functions, init_gif_functions, init_svg_functions):
1936 Arglist and w32_delayed_load calling convention changed.
1937 (gs_type): Remove init_gs_functions; there is no such function.
1938 (valid_image_p, make_image): Fix caller to lookup_image_type.
1940 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
1942 Simplify and avoid signal-handling races (Bug#12471).
1944 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
1945 Avoid recursive loop if there's a fatal error in the function itself.
1946 * atimer.c (pending_atimers):
1947 * blockinput.h: Don't include "atimer.h"; no longer needed.
1948 (interrupt_input_pending): Remove. All uses removed.
1949 pending_signals now counts both atimers and ordinary interrupts.
1950 This is less racy than having three separate pending-signal flags.
1951 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
1953 Rename from their upper-case counterparts BLOCK_INPUT,
1954 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
1955 INPUT_BLOCKED_P, and turn into functions. All uses changed.
1956 This makes it easier to access volatile variables more accurately.
1957 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
1958 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
1959 that's more reliable if the code is buggy and sets
1960 interrupt_input_blocked to a negative value. All uses changed.
1961 * atimer.c (deliver_alarm_signal):
1962 Remove. No need to deliver this to the parent; any thread can
1963 handle this signal now. All uses replaced by underlying handler.
1964 * atimer.c (turn_on_atimers):
1965 * dispnew.c (handle_window_change_signal):
1966 * emacs.c (handle_danger_signal):
1967 * keyboard.c (kbd_buffer_get_event):
1968 Don't reestablish signal handler; not needed with sigaction.
1969 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
1971 Rework to avoid unnecessary accesses to volatile variables.
1972 (UNBLOCK_INPUT_TO): Now a function.
1973 (totally_unblock_input, unblock_input): New decls.
1974 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
1975 (init_data): Remove. Necessary stuff now done in init_signal.
1976 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
1977 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
1978 (fatal_error_code): Remove; no longer needed.
1979 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
1980 it doesn't always backtrace. All uses changed. No need to reset
1981 signal to default, since sigaction and/or die does that for us now.
1982 Use emacs_raise (FOO), not kill (getpid (), FOO).
1983 (main): Check more-accurately whether we're dumping.
1984 Move fatal-error setup to sysdep.c
1985 * floatfns.c: Do not include "syssignal.h"; no longer needed.
1986 * gtkutil.c (xg_get_file_name, xg_get_font):
1987 Remove no-longer-needed signal-mask manipulation.
1988 * keyboard.c, process.c (POLL_FOR_INPUT):
1989 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
1990 * keyboard.c (read_avail_input): Remove.
1991 All uses replaced by gobble_input.
1992 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
1993 (kbd_buffer_store_event_hold, gobble_input):
1994 (record_asynch_buffer_change) [USABLE_SIGIO]:
1995 (store_user_signal_events):
1996 No need to mess with signal mask.
1997 (gobble_input): If blocking input and there are terminals, simply
1998 set pending_signals to 1 and return. All hooks changed to not
1999 worry about whether input is blocked.
2000 (process_pending_signals): Clear pending_signals before processing
2001 them, in case a signal comes in while we're processing.
2002 By convention callers now test pending_signals before calling us.
2003 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
2004 New functions, to support changes to blockinput.h.
2005 (handle_input_available_signal): Now extern.
2006 (reinvoke_input_signal): Remove. All uses replaced by
2008 (quit_count): Now volatile, since a signal handler uses it.
2009 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
2010 All callers changed. Block SIGINT only if not already blocked.
2011 Clear sigmask reliably, even if Fsignal returns, which it can.
2012 Omit unnecessary accesses to volatile var.
2013 (quit_throw_to_read_char): No need to restore sigmask.
2014 * keyboard.c (gobble_input, handle_user_signal):
2015 * process.c (wait_reading_process_output):
2016 Call signal-handling code rather than killing ourselves.
2017 * lisp.h: Include <float.h>, for...
2018 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
2019 (pending_signals): Now volatile.
2020 (syms_of_data): Now const if IEEE floating point.
2021 (handle_input_available_signal) [USABLE_SIGIO]:
2022 (terminate_due_to_signal, record_child_status_change): New decls.
2023 * process.c (create_process): Avoid disaster if memory is exhausted
2024 while we're processing a vfork, by tightening the critical section
2026 (send_process_frame, process_sent_to, handle_pipe_signal)
2027 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
2029 (send_process): No need for setjmp/longjmp any more, since the
2030 SIGPIPE stuff is now gone. Instead, report an error if errno
2032 (record_child_status_change): Now extern. PID and W are now args.
2033 Return void, not bool. All callers changed.
2034 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
2035 Remove. All uses removed. This bug should be fixed now in a
2037 (wait_for_termination_1): Use waitpid rather than sigsuspend,
2038 and record the child status change directly. This avoids the
2039 need to futz with the signal mask.
2040 (process_fatal_action): Move here from emacs.c.
2041 (emacs_sigaction_flags): New function, containing
2042 much of what used to be in emacs_sigaction_init.
2043 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
2044 caught by emacs, to make races less likely.
2045 (deliver_process_signal): Rename from handle_on_main_thread.
2047 (BACKTRACE_LIMIT_MAX): Now at top level.
2048 (thread_backtrace_buffer, threadback_backtrace_pointers):
2050 (deliver_thread_signal, deliver_fatal_thread_signal):
2051 New functions, for more-accurate delivery of thread-specific signals.
2052 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
2053 (deliver_arith_signal): Handle in this thread, not
2054 in the main thread, since it's triggered by this thread.
2055 (maybe_fatal_sig): New function.
2056 (init_signals): New arg DUMPING so that we can be more accurate
2057 about whether we're dumping. Caller changed.
2058 Treat thread-specific signals differently from process-general signals.
2059 Block all signals while handling fatal error; that's safer.
2060 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
2062 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
2063 Ignore SIGPIPE unless batch.
2064 (emacs_backtrace): Output backtrace for the appropriate thread,
2065 which is not necessarily the main thread.
2066 * syssignal.h: Include <stdbool.h>.
2067 (emacs_raise): New macro.
2068 * xterm.c (x_connection_signal): Remove; no longer needed
2069 now that we use sigaction.
2070 (x_connection_closed): No need to mess with sigmask now.
2071 (x_initialize): No need to reset SIGPIPE handler here, since
2072 init_signals does this for us now.
2074 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
2076 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
2077 background rect may be larger (Bug#12245).
2079 2012-09-23 Chong Yidong <cyd@gnu.org>
2081 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
2083 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
2085 * .gdbinit: Just stop at fatal_error_backtrace.
2086 See Stefan Monnier's request in
2087 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
2088 Remove no-longer-used query of system type.
2090 2012-09-22 Chong Yidong <cyd@gnu.org>
2092 * search.c (Freplace_match): Doc fix (Bug#12325).
2094 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
2096 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
2097 (Fline_end_position): Doc fix.
2099 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
2101 2012-09-22 Chong Yidong <cyd@gnu.org>
2103 * dispextern.h (struct image_type): Add new slot, storing a type
2104 initialization function.
2106 * image.c (define_image_type): Call the image initializer function
2107 if it is defined. Arguments and return value changed.
2108 (valid_image_p, make_image): Callers changed.
2109 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
2110 (gif_type, imagemagick_type, svg_type, gs_type):
2111 Add initialization functions.
2112 (Finit_image_library): Call lookup_image_type.
2113 (CHECK_LIB_AVAILABLE): Macro deleted.
2114 (lookup_image_type): Call define_image_type here, rather than via
2115 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
2116 (syms_of_image): Move define_image_type calls for xbm_type and
2117 pbm_type to lookup_image_type.
2119 2012-09-22 Eli Zaretskii <eliz@gnu.org>
2121 * keyboard.c (timer_check_2): Move calculation of 'timers' and
2122 'idle_timers' from here ...
2123 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
2124 lists, to avoid infloops when the timer does something stupid,
2125 like reinvoke itself with the same or smaller time-out.
2128 2012-09-22 Martin Rudalics <rudalics@gmx.at>
2130 * window.c (Fsplit_window_internal): Handle only Qt value of
2131 Vwindow_combination_limit separately.
2132 (Qtemp_buffer_resize): New symbol.
2133 (Vwindow_combination_limit): New default value.
2136 2012-09-22 Eli Zaretskii <eliz@gnu.org>
2138 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
2139 the new overlay string. (Bug#10159)
2141 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
2143 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
2144 or that fprintf is async-signal-safe. POSIX doesn't require
2147 2012-09-22 Chong Yidong <cyd@gnu.org>
2149 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
2152 2012-09-22 Kenichi Handa <handa@gnu.org>
2154 * composite.c (composition_reseat_it): Handle the case that a
2155 grapheme cluster is not covered by a single font (Bug#12352).
2157 2012-09-21 Chong Yidong <cyd@gnu.org>
2159 * image.c (define_image_type): Avoid adding duplicate types to
2160 image_types (Bug#12463). Suggested by Jörg Walter.
2162 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2164 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
2165 (print_load_command_name): Add case LC_DATA_IN_CODE.
2166 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
2168 2012-09-21 Glenn Morris <rgm@gnu.org>
2170 * eval.c (Frun_hook_with_args_until_success)
2171 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
2173 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
2175 * fileio.c (Ffile_selinux_context): Only call freecon when
2176 lgetfilecon succeeded.
2177 (Fset_file_selinux_context): Likewise. (Bug#12444)
2179 2012-09-21 Eli Zaretskii <eliz@gnu.org>
2181 * xdisp.c (try_window_reusing_current_matrix): Under bidi
2182 reordering, locate the cursor by calling set_cursor_from_row; if
2183 that fails, clear the desired glyph matrix before returning a
2184 failure indication to the caller. Fixes leaving garbled display
2185 when fast scrolling with a down-key. (Bug#12403)
2186 (compute_stop_pos_backwards): Fix a typo that caused crashes while
2187 scrolling through multibyte text.
2189 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
2191 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
2192 calling mark_vectorlike since that's the one that marks the window.
2193 (mark_discard_killed_buffers): Mark the final cdr.
2194 * window.h (struct window): Move prev/next_buffers to the
2195 non-standard fields.
2196 * window.c (make_window): Initialize prev/next_buffers manually.
2198 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
2200 Omit unused arg EXPECTED from socket hooks.
2201 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
2202 * nsterm.m (ns_term_init):
2203 * termhooks.h (struct terminal.read_socket_hook):
2204 * w32inevt.c (w32_console_read_socket):
2205 * w32term.c (w32_read_socket):
2206 * xterm.c (XTread_socket):
2207 Omit unused arg EXPECTED. All callers changed.
2208 (store_user_signal_events): Return void, not int, since callers no
2209 longer care about the return value. All uses changed.
2211 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
2213 * w32gui.h (XParseGeometry): Do not declare.
2215 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
2217 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
2218 Ignore 'expected'. See Eli Zaretskii in
2219 <http://bugs.gnu.org/12471#8> (last line).
2221 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
2222 (XParseGeometry): Now static. Substitute extremal values for
2223 values that are out of range.
2225 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
2227 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
2229 * nsfns.m (XParseGeometry): Remove.
2230 (Fx_create_frame): Call x_set_offset to correctly interpret
2231 top_pos in geometry.
2233 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
2234 (Fx_parse_geometry): If there is a space in string, call
2235 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
2237 2012-09-17 Eli Zaretskii <eliz@gnu.org>
2239 * search.c (scan_buffer): Use character positions in calls to
2240 region_cache_forward and region_cache_backward, not byte
2241 positions. (Bug#12196)
2243 * w32term.c (w32_read_socket): Set pending_signals to 1, like
2244 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
2246 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
2247 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
2248 emacs_blocked_malloc, now deleted.
2250 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
2252 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
2253 The workaround was for improving performance on Solaris 2.4, but
2254 is getting in the way now. Emacs will still work if someone is
2255 still running Solaris 2.4 in a museum somewhere; Sun dropped
2256 support for Solaris 2.4 in 2003.
2257 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
2258 * process.c (create_process) [HAVE_WORKING_VFORK]:
2259 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
2260 since Emacs no longer uses vfork on that platform.
2262 2012-09-17 Glenn Morris <rgm@gnu.org>
2264 * emacs.c: Use COPYRIGHT.
2266 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
2268 Remove configure's --without-sync-input option (Bug#12450).
2269 When auditing signal-handling in preparation for cleaning it up,
2270 I found that SYNC_INPUT has race conditions and would be a real
2271 pain to fix. Since it's an undocumented and deprecated
2272 configure-time option, now seems like a good time to remove it.
2273 Also see <http://bugs.gnu.org/11080#16>.
2274 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
2275 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
2276 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
2277 (malloc_hysteresis):
2278 (check_depth) [XMALLOC_OVERRUN_CHECK]:
2279 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
2280 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
2281 (dont_register_blocks, bytes_used_when_reconsidered)
2282 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
2283 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
2284 [!SYSTEM_MALLOC && !SYNC_INPUT]:
2285 Remove. All uses removed.
2286 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
2287 implementation, one that depends on whether the new macro
2288 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
2290 * atimer.c (run_timers, handle_alarm_signal):
2291 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
2292 (handle_async_input, process_pending_signals)
2293 (handle_input_available_signal, init_keyboard):
2294 * nsterm.m (ns_read_socket):
2295 * process.c (wait_reading_process_output):
2296 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
2297 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
2299 * xterm.c (XTread_socket):
2301 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
2302 * eval.c (handling_signal): Remove. All uses removed.
2303 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
2304 All uses replaced with the SYNC_INPUT version.
2305 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
2307 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2310 * font.c (Ffont_shape_gstring): Remove unused local.
2312 2012-09-16 Glenn Morris <rgm@gnu.org>
2314 * Makefile.in (clean): No longer run nextstep's clean.
2316 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
2318 (ns-app): Move here from ns.mk, and simplify.
2319 (clean): Simplify nextstep entry.
2320 * ns.mk: Remove file.
2322 2012-09-17 Kenichi Handa <handa@gnu.org>
2324 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
2325 not covert the last few charactes.
2327 2012-09-16 Kenichi Handa <handa@gnu.org>
2329 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
2330 here, but just check the validity of glyphs in the glyph-string.
2332 2012-09-16 Martin Rudalics <rudalics@gmx.at>
2334 * window.c (Fwindow_parameter, Fset_window_parameter):
2335 Accept any window as argument (Bug#12452).
2337 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
2339 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
2340 to ns_term_init to avoid memory leak.
2342 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
2343 explicit retain/release.
2344 (ns_term_init): Only allow one display. Initialize outerpool and
2347 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
2349 Port _setjmp fix to POSIXish hosts as well as Microsoft.
2350 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
2351 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
2352 the Microsoft problem in a different way, by altering ../nt/config.nt.
2354 2012-09-15 Eli Zaretskii <eliz@gnu.org>
2369 * w16select.c: Remove inclusion of setjmp.h, as it is now included
2370 by lisp.h. This completes removal of setjmp.h inclusion
2371 erroneously announced in the previous commit. (Bug#12446)
2373 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
2376 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
2377 not defined as a macro. The latter happens on MS-Windows.
2380 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
2382 Port better to POSIX hosts lacking _setjmp (Bug#12446).
2383 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
2384 Some instances of '#include <setjmp.h>' removed, if the
2385 only reason for the instance was because "lisp.h" was included.
2386 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
2387 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
2388 and _longjmp with the new symbols. Emacs already uses _setjmp if
2389 available, so this change affects only POSIXish hosts that have
2390 sigsetjmp but not _setjmp, such as some versions of Solaris and
2391 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
2392 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
2393 (png_load_body) [HAVE_PNG]:
2394 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
2395 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
2396 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
2397 since PNG requires jmp_buf. This is the only exception to the
2398 general rule that we now use sys_setjmp and sys_longjmp.
2399 This exception is OK since this code does not change the signal
2400 mask or longjmp out of a signal handler.
2402 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
2404 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
2405 Include "syssignal.h", for 'main_thread'.
2407 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
2409 Avoid out-of-range marker position (Bug#12426).
2410 * insdel.c (replace_range, replace_range_2):
2411 Adjust markers before overlays, as suggested by comments.
2412 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
2413 Remove redundant check before calling offset_intervals.
2415 2012-09-14 Martin Rudalics <rudalics@gmx.at>
2417 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
2418 current buffer (Bug#12387).
2420 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
2422 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
2424 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
2426 Use a more backwards-compatible timer format (Bug#12430).
2427 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
2428 vector element, not from the 4th, since PSECS is now at the end.
2429 (Fcurrent_idle_time): Doc fix.
2431 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
2433 Function to mark objects and remove killed buffers at once.
2434 * alloc.c (discard_killed_buffers): Rename to ...
2435 (mark_discard_killed buffers) ... new name. Add marking
2436 of remaining objects. Fix comment. Adjust users.
2437 (mark_object): Do not touch frame buffer lists here.
2438 * frame.c (delete_frame): Reset frame buffer lists here.
2440 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
2442 Better workaround for GNOME bug when --enable-gcc-warnings.
2443 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
2444 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
2445 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
2447 Simplify SIGIO usage (Bug#12408).
2448 The code that dealt with SIGIO was crufty and confusing, e.g., it
2449 played tricks like "#undef SIGIO" but these tricks were not used
2450 consistently. Simplify mostly by not #undeffing standard symbols,
2451 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
2452 or not as we please) rather than "defined SIGIO" (standard symbol
2453 that we probably shouldn't #undef).
2454 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
2455 Modules that need it can include it.
2456 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
2457 * dispextern.h (ignore_sigio): New decl.
2458 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
2459 unconditionally, since it's now a no-op if !USABLE_SIGIO.
2460 * emacs.c (shut_down_emacs):
2461 * keyboard.c (kbd_buffer_store_event_hold):
2462 Use ignore_sigio rather than invoking 'signal' directly.
2463 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
2465 (FIONREAD, SIGIO): Do not #undef.
2466 (tty_read_avail_input): Use #error rather than a syntax error.
2467 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
2468 for I_PIPE, used by SETUP_SLAVE_PTY.
2469 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
2470 * sysdep.c (croak): Remove; no longer needed. This bit of
2471 temporary code, with Fred N. Fish's comment that it's temporary,
2472 has been in Emacs since at least 1992!
2473 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
2474 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
2475 * syssignal.h (croak): Remove decl.
2476 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
2477 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
2478 now that we're termios-only.
2479 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
2480 * term.c (dissociate_if_controlling_tty): Use #error rather than
2483 Work around GCC and GNOME bugs when --enable-gcc-warnings.
2484 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
2485 to work around GNOME bug 683906.
2486 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
2487 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
2488 This works around GCC bug 54561.
2490 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
2492 More fixes for 'volatile' and setjmp/longjmp.
2493 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
2494 * image.c (struct png_load_context) [HAVE_PNG]: New type.
2495 (png_load_body) [HAVE_PNG]:
2496 (jpeg_load_body) [HAVE_JPEG]:
2497 New function, with most of the old parent function's body.
2498 (png_load) [HAVE_PNG]:
2499 (jpeg_load) [HAVE_JPEG]:
2500 Invoke the new function, to avoid longjmp munging our locals.
2501 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
2502 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
2503 longjmp is passed 2, as the C standard doesn't guarantee this.
2504 Instead, store the failure code into mgr->failure_code.
2506 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
2508 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
2509 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
2510 (syms_of_keyboard): Remove support for unread-command-char.
2512 2012-09-12 Eli Zaretskii <eliz@gnu.org>
2514 * w32proc.c (sys_kill): If PID is our process ID and the signal is
2515 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
2516 violation. (Bug#12426)
2518 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
2520 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
2522 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
2524 * eval.c: Add `inhibit-debugger'.
2525 (Qinhibit_debugger): New symbol.
2526 (call_debugger): Bind it instead of Qdebug_on_error.
2527 (maybe_call_debugger): Test Vinhibit_debugger.
2528 (syms_of_eval): Define inhibit-debugger.
2529 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
2530 (syms_of_xdisp): Remove inhibit-debug-on-message.
2532 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
2534 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
2535 If a nonvolatile local variable is written before a _longjmp to
2536 the frame containing the variable, and is read after the _longjmp,
2537 the value read is indeterminate. Some local variables of type
2538 'struct handler' and 'struct catchtag' are used in this way, so
2539 mark each of their slots as volatile if the slot can be set before
2540 _longjmp and read afterwards.
2541 * lisp.h (struct handler): var and chosen_clause are now volatile.
2542 (struct catchtag): val, next, and pdlcount are now volatile.
2544 * bidi.c (bidi_push_it, bidi_pop_it):
2545 * fns.c (copy_hash_table):
2546 * image.c (define_image_type):
2547 * keyboard.c (kbd_buffer_store_event_hold):
2548 * process.c (Fprocess_send_eof):
2549 * xfaces.c (x_create_gc) [HAVE_NS]:
2550 * xgselect.c (xg_select):
2551 Prefer assignment to memcpy when either will do.
2553 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
2554 Use pointer-to-a-pointer to simplify and avoid a NILP check each
2555 time an item is removed. No need to mark this function 'inline';
2556 the compiler knows better than we do.
2558 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
2560 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
2561 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
2562 to change_frame_size (Bug#12388).
2563 (windowDidResize:): Pass YES to updateFrameSize.
2565 * nsterm.h: Add delay parameter to updateFrameSize.
2567 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
2569 Discard killed buffers from deleted window and frame objects.
2570 This reduces an amount of references to killed buffers and
2571 helps GC to reclaim them faster.
2572 * alloc.c (discard_killed_buffers): New function.
2573 (mark_object): Use it for deleted windows and frames.
2574 (mark_object): If symbol's value is set up for a killed buffer
2575 or deleted frame, restore its global binding.
2576 * data.c (swap_in_global_binding): Add GC notice.
2577 (swap_in_symval_forwarding): Use convenient set_blv_where.
2578 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
2579 * window.h: ... to here.
2581 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
2583 Convenient macro to check whether the buffer is live.
2584 * buffer.h (BUFFER_LIVE_P): New macro.
2585 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
2586 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
2588 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2590 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
2591 composition cases (Bug#12364).
2593 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
2594 overhang of succeeding glyphs overlapping box cursor.
2596 * w32term.c (x_draw_glyph_string): Likewise.
2598 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
2600 Simplify, document, and port floating-point (Bug#12381).
2601 The porting part of this patch fixes bugs on non-IEEE platforms
2602 with frexp, ldexp, logb.
2603 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
2605 * floatfns.c: Simplify discussion of functions that Emacs doesn't
2606 support, by removing commented-out code and briefly listing the
2607 C89 functions excluded. The commented-out stuff was confusing
2608 maintenance, e.g., we thought we needed cbrt but it was commented out.
2609 (logb): Remove decl; no longer needed.
2610 (isfinite): New macro, if not already supplied.
2611 (isnan): Don't replace any existing macro.
2612 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
2613 are present on all C89 platforms.
2614 (Ffrexp): Do not special-case zero, as frexp does the right thing
2616 (Flogb): Do not use logb, as it doesn't have the desired meaning
2617 on hosts that use non-base-2 floating point. Instead, stick with
2618 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
2619 frexp, to avoid getting an unspecified result.
2621 * xdisp.c (Qinhibit_debug_on_message): Now static.
2623 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
2625 * nsterm.m (ns_update_begin): Set clip path to whole view by using
2626 NSBezierPath (Bug#12131).
2628 2012-09-10 Chong Yidong <cyd@gnu.org>
2630 * fns.c (Fdelq, Fdelete): Doc fix.
2632 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
2634 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
2635 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
2637 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
2639 * lisp.h (make_lisp_ptr): New macro to replace XSET.
2640 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
2643 2012-09-09 Eli Zaretskii <eliz@gnu.org>
2645 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
2646 left fringe if the window has a left margin. This avoids leaving
2647 traces of the cursor because its leftmost pixel is not drawn over.
2649 * dispnew.c (update_window_line): When the left margin area of a
2650 screen line is updated, set the redraw_fringe_bitmaps_p flag of
2651 that screen line. (Bug#12277)
2653 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
2655 Assume C89 or later for math functions (Bug#12381).
2656 This simplifies the code, and makes it a bit smaller and faster,
2657 and (most important) makes it easier to clean up signal handling
2658 since we can stop worring about floating-point exceptions in
2659 library code. That was a problem before C89, but the problem
2660 went away many years ago on all practical Emacs targets.
2661 * data.c, image.c, lread.c, print.c:
2662 Don't include <math.h>; no longer needed.
2663 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
2664 might be autoconfigured, as that never happens.
2666 * doprnt.c (DBL_MAX_10_EXP):
2667 * print.c (DBL_DIG):
2668 Remove. C89 or later always defines these.
2669 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
2670 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
2671 (arith_error, domain_error, domain_error2):
2672 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
2673 no longer needed -- we simply return what C returns. All uses removed.
2674 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
2676 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
2677 Remove. All uses expanded, as these macros are no longer used
2678 more than once and are now more trouble than they're worth.
2679 (Ftan): Use tan, not sin / cos.
2680 (Flogb): Assume C89 frexp.
2681 (fmod_float): Assume C89 fmod.
2682 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
2683 (init_floatfns): Remove. All uses removed.
2685 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2687 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
2688 compositeToPoint for OSX < 10.6 (Bug#12390).
2690 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
2692 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
2693 This produces more-accurate results.
2695 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2697 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
2698 changes (Bug#12088).
2700 2012-09-08 Chong Yidong <cyd@gnu.org>
2702 * syntax.c (Fstring_to_syntax): Doc fix.
2704 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2706 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
2707 in the internal border.
2708 (x_set_window_size): Remove static variables and their usage.
2709 (ns_redraw_scroll_bars): Fix NSTRACE arg.
2710 (ns_after_update_window_line, ns_draw_fringe_bitmap):
2711 Remove fringe/internal border adjustment (Bug#11052).
2712 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
2713 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
2714 (ns_fix_rect_ibw): Remove.
2715 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
2716 (ns_dumpglyphs_box_or_relief): Ditto.
2717 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
2719 (ns_dumpglyphs_image): Ditto.
2720 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
2722 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
2723 their usage. Add fringe_extended_p and its use as in other terms.
2724 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
2725 scroll bar was removed.
2726 (updateFrameSize): New function.
2727 (windowDidResize): Move code to updateFrameSize and call it.
2729 * nsterm.h (EmacsView): Add updateFrameSize.
2731 2012-09-07 Chong Yidong <cyd@gnu.org>
2733 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
2735 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
2737 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
2739 More signal-handler cleanup (Bug#12327).
2740 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
2741 Problem introduced when merging patches. Noted by Eli Zaretskii in
2742 <http://bugs.gnu.org/12327#67>.
2743 * floatfns.c: Comment fix.
2744 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
2745 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
2746 and anyway the declaration is harmless even if SIGDANGER is not defined.
2747 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
2748 defined BROKEN_FIONREAD). systty.h formerly did this, but other
2749 source files not surprisingly expected syssignal.h to define, or
2750 not define, SIGIO, and it's cleaner to do it that way, for consistency.
2751 Include <sys/ioctl.h>, for FIONREAD.
2752 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
2753 This eliminates a problem whereby other files mysteriously had
2754 to include "syssignal.h" before including "systty.h" if they
2755 wanted to use "#ifdef SIGIO".
2757 2012-09-07 Eli Zaretskii <eliz@gnu.org>
2759 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
2761 * w32.c (sigemptyset): Empty the set.
2762 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
2764 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
2766 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
2768 * alloc.c (mark_buffer): Revert unsafe marking optimization.
2769 (mark_object): Likewise for frame objects.
2771 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
2773 * syssignal.h (handle_on_main_thread): Always declare,
2774 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
2775 This ports to platforms without HAVE_PTHREAD.
2777 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
2779 Signal-handler cleanup (Bug#12327).
2780 Emacs's signal handlers were written in the old 4.2BSD style with
2781 sigblock and sigmask and so forth, and this led to some
2782 inefficiencies and confusion. Rewrite these to use
2783 pthread_sigmask etc. without copying signal sets around. Also,
2784 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
2785 'signal', and instead use functions that do not attempt to take
2786 over the system name space. This patch causes Emacs's text
2787 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
2788 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
2789 Do not include <signal.h> or "syssignal.h", as these
2790 modules do not use signals.
2791 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
2792 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
2793 Do not include <signal.h>, as "syssignal.h" does that for us now.
2794 * atimer.c (sigmask_atimers): New function.
2795 (block_atimers, unblock_atimers): New functions,
2796 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
2798 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
2799 no longer needed here.
2800 * emacs.c (main): Inspect existing signal handler with sigaction,
2801 so that there's no need to block and unblock SIGHUP.
2802 * sysdep.c (struct save_signal): New member 'action', replacing
2803 old member 'handler'.
2804 (save_signal_handlers, restore_signal_handlers):
2805 Use sigaction instead of 'signal' to save and restore.
2806 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
2807 New function. All users of 'signal' modified to use set_sighandler
2808 if they're writeonly, and to use sys_signal if they're read+write.
2809 (emacs_sigaction_init, forwarded_signal): New functions.
2810 (sys_signal): Remove. All uses replaced by calls to sigaction
2811 and emacs_sigaction_init, or by direct calls to 'signal'.
2812 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
2813 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
2814 all uses replaced by pthread_sigmask etc. calls.
2815 * syssignal.h: Include <signal.h>.
2816 (emacs_sigaction_init, forwarded_signal): New decls.
2817 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
2818 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
2819 (sigmask, sys_sigmask): Remove; no longer needed.
2820 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
2821 (sigblock, sigunblock, sigfree):
2822 (sigsetmask) [!defined sigsetmask]:
2823 Remove. All uses replaced by pthread_sigmask.
2824 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
2825 no longer need to be replaced, and its typical old uses
2826 are now done via emacs_sigaction_init and sigaction.
2827 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
2828 (sys_sigdel): Remove; unused.
2829 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
2831 2012-09-06 Eli Zaretskii <eliz@gnu.org>
2833 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
2834 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
2836 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
2838 Explicitly mark buffer_defaults and buffer_local_symbols.
2839 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
2840 mark_local_symbols here.
2841 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
2842 since special buffers aren't marked here any more.
2843 (allocate_buffer): Chain new buffer with all_buffers here...
2844 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
2846 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
2847 (syms_of_buffer): Remove staticpro of the above.
2848 (init_buffer_once): Set names for buffer_defaults and
2849 buffer_local_symbols.
2851 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
2853 Use bool for booleans in font-related modules.
2854 * font.c (font_intern_prop, font_style_to_value)
2855 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
2856 (generate_otf_features, font_check_otf_features, font_check_otf)
2857 (font_match_p, font_list_entities, font_at):
2858 * fontset.c (fontset_id_valid_p, reorder_font_vector
2859 (fontset_find_font, Fset_fontset_font)
2860 (face_suitable_for_char_p) [0]:
2861 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
2862 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
2863 (m17n_flt_initialized, ftfont_shape_by_flt):
2864 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
2865 * nsfont.m (nsfont_draw):
2866 * w32font.c (w32font_draw):
2867 * w32term.c (x_draw_glyphless_glyph_string_foreground):
2868 Use bool for booleans.
2869 * font.h: Adjust to above API changes.
2870 (struct font, struct font_driver, struct font_driver_list):
2871 Use bool for booleans.
2872 (struct font): Remove useless member encoding_type.
2874 * fontset.c, xftfont.c: Omit unnecessary static decls.
2876 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
2878 * alloc.c (mark_object): Revert window marking code
2879 since it's unsafe for the Fset_window_configuration.
2881 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
2883 Fix race conditions with signal handlers and errno (Bug#12327).
2884 Be more systematic about preserving errno whenever a signal
2885 handler returns, even if it's not in the main thread. Do this by
2886 renaming signal handlers to distinguish between signal delivery
2887 and signal handling. All uses changed.
2888 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
2889 * data.c (deliver_arith_signal): Rename from arith_error.
2890 * dispnew.c (deliver_window_change_signal): Rename from
2891 window_change_signal.
2892 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
2893 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
2894 * keyboard.c (deliver_input_available_signal): Rename from
2895 input_available_signal.
2896 (deliver_user_signal): Rename from handle_user_signal.
2897 (deliver_interrupt_signal): Rename from interrupt_signal.
2898 * process.c (deliver_pipe_signal): Rename from send_process_trap.
2899 (deliver_child_signal): Rename from sigchld_handler.
2900 * atimer.c (handle_alarm_signal):
2901 * data.c (handle_arith_signal):
2902 * dispnew.c (handle_window_change_signal):
2903 * emacs.c (handle_fatal_signal, handle_danger_signal):
2904 * keyboard.c (handle_input_available_signal):
2905 * keyboard.c (handle_user_signal, handle_interrupt_signal):
2906 * process.c (handle_pipe_signal, handle_child_signal):
2907 New functions, with the actual signal-handling code taken from the
2908 original respective signal handlers, sans the sporadic attempts to
2909 preserve errno, since that's now done by handle_on_main_thread.
2910 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
2911 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
2912 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2914 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2915 Move initialization of main_thread to sysdep.c's init_signals.
2916 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
2917 our usage, and simplifies the mainline code.
2918 (record_child_status_change): New static function, as a helper
2919 for handle_child_signal, and with most of the old child handler's
2921 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
2922 (handle_child_signal): Use the above.
2923 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2924 Moved here from emacs.c.
2925 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
2926 code moved here from emacs.c's main function.
2927 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
2928 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
2929 This lets callers save and restore errno properly.
2931 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2933 Remove redundant or unused things here and there.
2934 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
2935 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
2936 * editfns.c (Fcompare_buffer_substrings): Likewise.
2937 * frame.h (struct terminal, struct font_driver_list):
2938 Remove redundant declarations.
2939 * window.h (Qleft, Qright): Likewise.
2941 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2943 Do not mark objects from deleted buffers, windows and frames.
2944 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
2945 (mark_object): Likewise for windows and frames.
2947 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2949 * alloc.c (valid_lisp_object_p): Treat killed buffers,
2950 buffer_defaults and buffer_local_symbols as valid objects.
2951 Return special value to denote them.
2953 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
2955 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
2956 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
2957 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
2958 (file_name_absolute_p, Fsubstitute_in_file_name):
2959 (check_executable, check_writable, Ffile_accessible_directory_p)
2960 (Fset_file_selinux_context, Fdefault_file_modes)
2961 (Finsert_file_contents, choose_write_coding_system)
2962 (Fwrite_region, build_annotations, a_write, e_write)
2964 * filelock.c (boot_time_initialized, get_boot_time)
2965 (get_boot_time_1, lock_file_1, within_one_second):
2966 * floatfns.c (in_float):
2967 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
2968 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
2969 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
2970 * lisp.h (struct Lisp_Hash_Table.cmpfn):
2971 * window.c (compare_window_configurations):
2972 Use bool for booleans.
2973 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
2974 (Fdefault_file_modes): Now mode_t, not int, for modes.
2975 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
2976 (internal_delete_file): Now returns void, not a (boolean) int,
2977 since nobody was looking at the return value.
2978 * lisp.h, window.h: Adjust to above API changes.
2980 * xdisp.c (set_message): Simplify and reindent last change.
2982 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
2984 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
2986 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
2988 * eval.c (call_debugger): Make the function non-static so that we
2989 can call it from set_message.
2991 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
2992 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
2994 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2996 Give more-useful info on a fatal error (Bug#12328).
2997 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
2998 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
2999 of doing the work ourselves.
3000 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
3001 do most of the work.
3002 (fatal_error_backtrace): New function, taken from the guts
3003 of the old fatal_error_signal, but with a new option to output
3005 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
3006 info about the signal than just its number.
3007 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
3008 * sysdep.c: Include <execinfo.h>
3009 (emacs_backtrace): New function, taken partly from the previous
3010 code of the 'die' function.
3011 (emacs_abort): Call fatal_error_backtrace rather than abort.
3013 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
3015 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
3016 eager (load-time) macro-expansion.
3017 * lisp.mk (lisp): Add macroexp.
3019 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3021 Simplify redefinition of 'abort' (Bug#12316).
3022 Do not try to redefine the 'abort' function. Instead, redo
3023 the code so that it calls 'emacs_abort' rather than 'abort'.
3024 This removes the need for the NO_ABORT configure-time macro
3025 and makes it easier to change the abort code to do a backtrace.
3026 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
3027 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
3028 Remove; sysdep.c's emacs_abort now takes its place.
3029 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
3030 'abort' changed to use 'emacs_abort'.
3031 * msdos.c (dos_abort) [defined abort]: Remove; not used.
3032 (abort) [!defined abort]: Rename to ...
3033 (emacs_abort): ... new name.
3034 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
3035 the place of the old 'abort' in emacs.c.
3036 * w32.c, w32fns.c (abort): Do not #undef.
3037 * w32.c (emacs_abort): Rename from w32_abort.
3039 2012-09-04 Eli Zaretskii <eliz@gnu.org>
3041 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
3042 offsets[j].dv, since the y axis of the screen coordinates points
3043 down, while the y axis of the font definition coordinates points
3044 up. This fixes display of Arabic diacritics such as KASRA and
3045 KASRATAN. (Bug#11860)
3047 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3049 Be more systematic about _setjmp vs setjmp.
3050 * alloc.c (test_setjmp, mark_stack):
3051 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
3052 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
3053 (png_load, my_error_exit, jpeg_load):
3054 * process.c (send_process_trap, send_process):
3055 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
3056 The underscored versions are up to 30x faster on some hosts.
3057 Formerly, the code used setjmp+longjmp sometimes and
3058 _setjmp+_longjmp at other times, with no particular reason to
3059 prefer setjmp+longjmp.
3061 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
3063 Fix minor problem found by static checking.
3064 * buffer.c (Fdelete_all_overlays): Return nil.
3066 2012-09-03 Martin Rudalics <rudalics@gmx.at>
3068 * buffer.c (Fdelete_all_overlays): New function.
3070 2012-09-03 Chong Yidong <cyd@gnu.org>
3072 * gtkutil.c: Add extern decl for Qxft.
3074 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
3076 * emacs.c, eval.c: Use bool for boolean.
3077 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
3078 (malloc_using_checking) [DOUG_LEA_MALLOC]:
3079 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
3080 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
3081 (main, decode_env_path, Fdaemon_initialized):

3083 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
3084 (maybe_call_debugger, Fbacktrace):
3085 * process.c (read_process_output, exec_sentinel):
3086 Use bool for booleans.
3087 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
3088 All callers changed.
3089 * eval.c (interactive_p): Omit always-true boolean argument
3090 EXCLUDE_SUBRS_P. All callers changed.
3091 * dispextern.h, lisp.h: Reflect above API changes.
3092 * firstfile.c (dummy): Use the address of 'main', whose signature
3093 won't change, instead of the address of 'initialize', whose
3094 signature just changed from int to bool.
3095 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
3096 * msdos.c (fatal_error_in_progress): ... from here.
3097 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
3099 (redisplay_internal, unwind_redisplay): Simply clear
3100 REDISPLAYING_P when unwinding, instead of saving its previous,
3101 always-false value and then restoring it.
3103 Clean up some extern decls.
3104 Mostly, this hoists extern decls out of .c files and into .h files.
3105 That way, we're more likely to catch errors if the interfaces change.
3106 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
3107 declare xg_mark_data.
3108 * dispextern.h (x_frame_parm_handlers):
3110 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
3111 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
3112 (Qultra_bold, Qoblique, Qitalic):
3113 Move extern decl here from .c file.
3114 * alloc.c (xg_mark_data) [USE_GTK]:
3116 * eval.c (Qlexical_binding):
3117 * fns.c (time) [!HAVE_UNISTD_H]:

3123 * process.c (QCfamily, QCfilter):
3124 * widget.c (free_frame_faces):
3125 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
3126 * xfont.c (x_clear_errors):
3127 * xterm.c (x_frame_parm_handlers):
3128 Remove now-redundant extern decls.
3129 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
3130 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
3132 * xfaces.c: Remove unnecessary static decls.
3133 * xterm.c (updating_frame): Remove decl of nonexistent object.
3135 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
3136 when building globals.h, as the objects that are not built on
3137 this host are not needed to compile C files on this host.
3139 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
3141 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
3143 * frame.h: Add missing prototype for x_wm_set_size_hint.
3145 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

3149 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
3150 (Fsubstitute_command_keys):

3152 (save_excursion_save, save_excursion_restore)
3153 (disassemble_lisp_time, decode_time_components, emacs_nmemftime)

3155 (make_buffer_string, make_buffer_string_both)
3156 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):

3166 (adjust_for_invis_intang, set_point_both)

3168 (set_intervals_multibyte_1, set_intervals_multibyte):
3169 * keyboard.c (decode_timer):
3170 Use bool for boolean.
3171 * intervals.h, lisp.h, systime.h: Reflect above API changes.
3172 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
3174 2012-09-02 Chong Yidong <cyd@gnu.org>
3176 * keymap.c (push_key_description): Print M-TAB as C-M-i
3179 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
3181 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
3182 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))
3183 ($(BLD)/editfns.$(O), $(BLD)/ccl.$(O), $(BLD)/chartab.$(O))

3187 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
3189 2012-09-01 Eli Zaretskii <eliz@gnu.org>
3191 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
3192 more than one grapheme cluster passed to the shaper: compute the
3193 offset adjustment values separately for each cluster. (Bug#11860)
3195 * image.c: Restore mistakenly removed inclusion of w32.h. Without
3196 it, GCC doesn't see prototypes of w32_delayed_load, and complains
3197 about implicit conversions from integer to pointer.
3199 2012-09-01 Daniel Colascione <dancol@dancol.org>
3201 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
3202 system used too early.
3204 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
3206 Better seed support for (random).
3207 * emacs.c (main): Call init_random.
3208 * fns.c (Frandom): Set the seed from a string argument, if given.
3209 Remove long-obsolete Gentzel cruft.
3210 * lisp.h, sysdep.c (seed_random): Now takes address and size, not long.
3211 (init_random): New function.
3213 2012-09-01 Daniel Colascione <dancol@dancol.org>
3215 * xterm.h: Add header guards. Declare x_menubar_window_to_frame.

3516 Special MEM_TYPE_SPARE to denote reserved memory.
3517 * alloc.c (enum mem_type): New memory type.
3518 (refill_memory_reserve): Use new type for spare memory.

3554 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
3555 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
3556 are all boolean, so make them single-bit bitfields.
3558 * lisp.h (ASET): Remove attempt to detect side effects.
3559 It was meant to be temporary and it often doesn't work,
3560 because when IDX has side effects the behavior of IDX==IDX
3561 is undefined. See Stefan Monnier in
3562 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
3564 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)

3567 (FUNCTIONP): Use it.

3572 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
3573 as that's faster and simpler than static storage. Don't bother
3574 with the g_main_context_query overhead if g_main_context_pending
3575 says no events are pending.
3576 (gfds, gfds_size): Remove these static vars.
3577 (xgselect_initialize): Remove; no longer needed.
3578 All uses and decls removed.
3580 * emacs.c (fatal_error_signal_hook): Remove.
3581 All uses removed. This leftover from old code was always 0.

3608 Use bool for booleans, instead of int.
3609 * lisp.h, process.h: Adjust prototypes to match above changes.
3610 * callint.c (Fcall_interactively): Don't assume the mark's
3611 offset fits in 'int'.

3624 Use bool for booleans, instead of int.
3625 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
3626 since the 1-or-0 return value is always ignored anyway.
3627 (mmap_initialized_p):
3628 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
3629 * buffer.h, lisp.h: Adjust prototypes to match above changes.
3631 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
3633 * bidi.c: Use bool for boolean.
3634 This is a bit more readable, and makes the text segment of bidi.o
3635 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
3636 Presumably it's faster too.

3670 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
3672 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
3673 Otherwise, the compiler complains about (A?B:C) where B is void
3674 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
3675 (fontset_add): Return void, for FONTSET_ADD.
3677 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3679 * alloc.c: Use bool for booleans.
3680 (gc_in_progress, abort_on_gc)
3681 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
3682 (dont_register_blocks) [GC_MALLOC_CHECK]:
3683 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
3684 (check_string_bytes, make_specified_string, memory_full)
3685 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
3686 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
3687 (mark_stack, valid_pointer_p, make_pure_string)
3688 (Fgarbage_collect, survives_gc_p, gc_sweep):
3689 Use bool for booleans, instead of int.
3690 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
3691 Remove unused local.
3692 * alloc.c (PURE_POINTER_P):
3693 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
3694 * editfns.c (Fformat):
3695 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
3697 * fns.c (sweep_weak_table):
3698 * lisp.h (suppress_checking, push_message, survives_gc_p)
3699 (make_pure_string, gc_in_progress, abort_on_gc):
3700 * lread.c (readchar, read1):
3701 * print.c (Fprin1_to_string):
3702 * xdisp.c (push_message):
3703 Use bool for booleans affected directly or indirectly by
3706 Make recently-introduced setters macros.
3707 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
3708 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
3709 (set_fontset_default, set_fontset_fallback): Rename from their
3710 upper-case counterparts, and make them functions rather than macros.
3711 This is more consistent with the other recently-introduced setters.
3712 These don't need to be inline, since they're local.
3714 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
3716 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
3717 the loop (Bug#12247).
3719 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3721 * lisp.h (vcopy): Use memcpy rather than our own loop.
3722 This fixes a performance regression introduced by the recent
3723 addition of vcopy. This means 'vcopy' will need to be modified
3724 for a copying collector, but that's OK. Also, tighten the
3725 checking in the assertion.
3727 2012-08-21 Eli Zaretskii <eliz@gnu.org>
3729 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
3730 components for RTL text (Bug#11860). Adjust X-OFFSET of each
3731 non-base glyph for the width of the base character, according to
3732 what x_draw_composite_glyph_string_foreground expects.
3733 Generate WADJUST value according to composition_gstring_width's
3734 expectations, to produce correct width of the composed character.
3735 Reverse the sign of the DU offset produced by ScriptPlace.
3737 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3739 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
3741 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
3743 Avoid direct writes to contents member of struct Lisp_Vector.
3744 * lisp.h (vcopy): New function to copy data into vector.
3745 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
3746 * fns.c (Ffillarray): Use ASET.
3747 * keyboard.c (timer_check_2): Use AREF and ASET.
3748 (append_tool_bar_item, Frecent_keys): Use vcopy.
3749 * lread.c (read_vector): Use ASET.
3750 * msdos.c (Frecent_doskeys): Use vcopy.
3751 * xface.c (Finternal_copy_lisp_face): Use vcopy.
3752 (Finternal_merge_in_global_face): Use ASET and vcopy.
3753 * xfont.c (xfont_list_pattern): Likewise.
3755 2012-08-21 Martin Rudalics <rudalics@gmx.at>
3757 * window.c (Fwindow_point): For the selected window always return
3758 the position of its buffer's point.
3759 (Fset_window_point): For the selected window always go in its
3760 buffer to the specified position.
3762 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
3764 Setter macros for fontsets.
3765 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
3766 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
3767 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
3770 2012-08-20 Glenn Morris <rgm@gnu.org>
3772 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
3773 Don't assume that `ln -f' works.
3775 2012-08-20 Eli Zaretskii <eliz@gnu.org>
3777 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
3778 and later about non-assignments with no effect. See discussion at
3779 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
3782 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3784 Inline setter functions for Lisp_Objects slots of struct specbinding.
3785 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
3788 2012-08-20 Martin Rudalics <rudalics@gmx.at>
3790 * window.c (select_window): Always make selected window's buffer
3793 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3795 Use AREF and ASET for docstrings of category tables.
3796 * category.h (CATEGORY_DOCSTRING): Use AREF.
3797 (SET_CATEGORY_DOCSTRING): Use ASET.
3798 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
3800 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3802 Inline setter functions for hash table members.
3803 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
3804 (set_hash_hash, set_hash_index): Rename with _slot suffix.
3805 (set_hash_key_and_value, set_hash_index, set_hash_next)
3806 (set_hash_hash): New functions.
3807 * charset.c, fns.c: Adjust users.
3809 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3811 Inline getter and setter functions for per-buffer values.
3812 * buffer.h (per_buffer_default, set_per_buffer_default)
3813 (per_buffer_value, set_per_buffer_value): New functions.
3814 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
3815 * buffer.c, data.c: Adjust users.
3817 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
3819 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
3821 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
3823 Rely on <config.h> + <unistd.h> to declare 'environ',
3824 as gnulib does this if the system doesn't.
3825 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
3826 Remove declaration. MS-Windows declares it on stdlib.h which is
3827 included by conf_post.h.
3828 * emacs.c (environ) [DOUG_LEA_MALLOC]:
3829 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
3830 * vm-limit.c: Include <unistd.h>, for 'environ'.
3832 * unexaix.c, unexcoff.c: Include "mem-limits.h".
3833 (start_of_data): Remove decl; mem-limits.h provides it.
3835 * xdisp.c (handle_invisible_prop): Make it a bit faster
3836 and avoid a gcc -Wmaybe-uninitialized diagnostic.
3838 2012-08-19 Chong Yidong <cyd@gnu.org>
3840 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
3843 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
3845 * .gdbinit: Use call instead of set when calling a function in the
3848 * data.c (set_internal): Don't use set_blv_found.
3849 (Fkill_local_variable): Likewise.
3851 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
3853 * nsfont.m (ns_ascii_average_width): Ensure the string
3854 ascii_printable is initialized with a null-terminated character
3855 array. Otherwise, it can contain undesired extra characters.
3857 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
3859 port new setting code to Sun C 5.8 2005/10/13
3860 * chartab.c, lisp.h (char_table_set, char_table_set_range):
3861 Return void, not Lisp_Object. Otherwise, the compiler
3862 complains about (A?B:C) where B is void and C is Lisp_Object
3863 when compiling CHAR_TABLE_SET, due to the recent change to
3864 the API of sub_char_table_set_contents.
3866 2012-08-18 Chong Yidong <cyd@gnu.org>
3868 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
3869 for the string case (Bug#3874).

4024 The old version was confusing because it used the same name
4025 'parent' for two different things.
4027 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>
4029 Functions to get and set Lisp_Object fields of buffer-local variables.

4038 font spec, make the font's attributes take precedence over
4039 directly-specified attributes.
4040 (merge_face_ref): Recognize :font.
4042 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>
4044 Do not use memcpy for copying intervals.
4045 * intervals.c (reproduce_interval): New function.

4065 2012-08-16 Paul Eggert <eggert@cs.ucla.edu>
4067 Use ASCII tests for character types.
4068 * category.c, dispnew.c, doprnt.c, editfns.c, syntax.c, term.c:
4070 Don't include <ctype.h>; was not needed.
4071 * charset.c, doc.c, fileio.c, font.c, frame.c, gtkutil.c, image.c:
4072 * sysdep.c, xfaces.c:
4073 Include <c-ctype.h> instead of <ctype.h>.

4088 * xfaces.c (hash_string_case_insensitive):
4089 Use C-locale tests instead of locale-specific tests for character
4090 types, since we want the ASCII interpretation here, not the
4091 interpretation suitable for whatever happens to be the current locale.

4696 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
4697 * w32.c (init_environment): Change the default values of many
4698 environment variables in dflt_envvars[] to NULL, to avoid pushing
4699 them into environment when they were not already defined.
4700 Remove the code that deletes site-lisp subdirectories from the default
4701 value of EMACSLOADPATH, as it is no longer needed.
4702 (check_windows_init_file): Now external, not static.
4703 Use Vload_path as is, without adding anything, as this function is now
4704 called when Vload_path is already set up.
4706 * w32.h (check_windows_init_file): Add prototype.
4708 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

4715 installation tree, as appropriate.
4717 * callproc.c (init_callproc_1): Call decode_env_path instead of
4718 doing its equivalent by hand.

4720 the code that sets Vexec_path run on MS-Windows.
4722 * lread.c (init_lread): Add comments to #ifdef's.
4724 * msdos.c (dos_set_window_size, IT_update_begin)

4736 Remove unnecessary casts involving pointers.
4737 These casts are no longer needed now that we assume C89 or later,

4751 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
4752 Remove unnecessary pointer casts.
4753 * alloc.c (record_xmalloc): New function.
4754 * lisp.h (record_xmalloc): New decl.
4755 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
4756 more like a function. This is because the pointer cast is not
4757 needed. All uses changed.
4758 * print.c (print_string, print_error_message): Avoid length recalc.
4760 Improve fix for macroexp crash with debugging (Bug#12118).
4761 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
4762 ARRAY_MARK_FLAG when checking subscripts, because ASET is
4763 not supposed to be invoked from the garbage collector.
4764 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
4765 (gc_aset): New function, which is like ASET but can be
4766 used in the garbage collector.
4767 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

4782 headers (most versions of MinGW w32api don't).
4783 (get_security_info, create_symbolic_link)
4784 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):

4791 have the required privileges.
4792 (get_file_security_desc_by_name): Rename from

4795 with addition of handling of symlinks and support for 'lstat'.
4796 If possible, get file's attributes and security information by
4797 handle, not by name. Produce S_IFLNK bit for symlinks, when
4798 called from 'lstat'.
4799 (stat, lstat): New functions, call 'stat_worker'.
4800 (symlink, readlink, careadlinkat): Rewritten to create and resolve
4801 symlinks when the underlying filesystem supports them.
4803 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
4805 Fix macroexp crash on Windows with debugging (Bug#12118).
4806 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
4807 checking subscripts; problem introduced with the recent
4808 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
4809 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
4810 since it's used in non-static inline functions now.
4812 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
4813 Don't assume buffer size fits in 'int'. Remove unused local.

4830 * category.c (CATEGORY_INLINE):
4831 * character.c (CHARACTER_INLINE):
4832 * charset.c (CHARSET_INLINE):
4833 * composite.c (COMPOSITE_INLINE):
4834 * dispnew.c (DISPEXTERN_INLINE):
4835 * sysdep.c (SYSTIME_INLINE):
4836 Define to EXTERN_INLINE, so that the corresponding functions
4837 are compiled into code.
4838 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
4839 (INLINE_HEADER_END): New macros.
4840 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

4860 hard-coding the path separator.
4862 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
4864 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
4865 This how ASET and AREF are supposed to work, and makes
4866 it easier to think about future improvements. See
4867 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
4868 * charset.h (set_charset_attr): New function.

5307 is an integer literal.
5308 (xgetint): Simplify expression.
5309 * alloc.c (gdb_make_enums_visible): New constant. This ports to

5358 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
5359 emacs.c, as this is a more-suitable home. Had this been done earlier
5360 the fix for 12036 would have avoided some of the problems noted in
5361 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
5362 would have been more obvious.
5363 * emacs.c: Do not include <verify.h>; no longer needed.

5372 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
5373 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
5374 not be usable in #if. This simplifies things.
5376 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
5378 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
5380 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

5383 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
5384 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
5385 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
5386 Adjust to changes in lisp.h and emacs.c, by using

5389 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of

5391 instead of gdb_valbits.
5392 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
5393 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
5394 instead of gdb_array_mark_flag.
5395 (xboolvector): Get size from $->size, not $->header.size.
5396 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
5397 (xreload, hook-run, hookpost-run): Remove.
5398 * emacs.c: Include <verify.h>.
5399 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
5400 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
5402 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
5403 (gdb_USE_LSB_TAG): New enum constants.
5404 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
5405 Also define these as enum constants, so they're visible to GDB.

5407 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these

5412 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is

6296 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
6297 Prefer snprintf to strncpy.
6298 * nsterm.m (ns_term_init):
6299 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
6300 * nsterm.m (ns_term_init):
6301 Avoid the need for strncpy, by using build_string or
6302 make_unibyte_string directly. Use dtoastr, not snprintf.
6303 * process.c (Fmake_network_process): Diagnose service names that
6304 are too long, rather than silently truncating them or creating
6305 non-null-terminated names.

6335 Optimize pure C strings initialization.
6336 * lisp.h (make_pure_string): Fix prototype.
6337 (build_pure_c_string): New function, defined as static inline. This
6338 provides a better opportunity to optimize away calls to strlen when
6339 the function is called with compile-time constant argument.
6340 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
6341 argument, adjust users accordingly. Use build_pure_c_string where
6343 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
6344 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
6345 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
6347 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
6349 Avoid calls to strlen in miscellaneous functions.
6350 * buffer.c (init_buffer): Use precalculated len, adjust if needed.

6356 Avoid calls to strlen in path processing functions.
6357 * fileio.c (file_name_as_directory): Add comment. Change to add
6358 srclen argument and return the length of result. Adjust users

6361 swap 1st and 2nd arguments to obey the common convention.
6362 Adjust users accordingly.
6363 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
6365 2012-07-10 Glenn Morris <rgm@gnu.org>

6372 * s/gnu.h (DATA_START): Move definitions to configure.
6374 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
6375 We include usg5-4-common.h, which defines them both.
6377 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
6378 O_RDONLY already includes it).
6380 Stop ns builds setting the EMACSLOADPATH environment variable.
6381 * nsterm.m (ns_load_path): Rename from ns_init_paths.
6382 Now it does not set EMACSLOADPATH, just returns the load-path string.
6383 * nsterm.h: Update accordingly.
6384 * lread.c [HAVE_NS]: Include nsterm.h.
6385 (init_lread) [HAVE_NS]: Use ns_load_path.

6388 2012-07-09 Glenn Morris <rgm@gnu.org>
6390 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
6391 since the included bsd-common.h does so.
6393 Stop ns builds setting the EMACSPATH environment variable.
6394 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
6395 (ns_init_paths): Do not set EMACSPATH.
6396 * nsterm.h (ns_exec_path): Add it.
6397 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
6400 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
6402 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
6404 * process.c (wait_reading_process_output): 'waitchannels' was unset
6405 when read_kbd || !NILP (wait_for_cell); fix this.
6407 Add GCC-style 'const' attribute to functions that can use it.
6408 * character.h (char_resolve_modifier_mask):
6409 * keyboard.h (make_ctrl_char):
6410 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

6417 Declare the dummy function with ATTRIBUTE_CONST.
6418 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
6419 Add decls with ATTRIBUTE_CONST.
6421 Minor improvements to make_formatted_string.
6422 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
6423 where int is good enough, as vsprintf returns an int.
6424 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
6426 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
6428 Use make_formatted_string to avoid double length calculation.
6429 * lisp.h (make_formatted_string): New prototype.
6430 * alloc.c (make_formatted_string): New function.
6431 * buffer.c (Fgenerate_new_buffer_name): Use it.

6453 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
6455 Move marker debugging code under MARKER_DEBUG.
6456 * marker.c (MARKER_DEBUG): Move marker debugging code under
6457 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
6458 for bootstrap with --enable-checking (~3x slowdown reported
6459 by Juanma Barranquero <lekktu@gmail.com>).
6460 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
6462 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
6464 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
6465 See <http://bugs.gnu.org/11825#29>.
6467 2012-07-08 Eli Zaretskii <eliz@gnu.org>
6469 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
6470 has no font, use the frame's font. (Bug#11813)
6471 (display_line): Add commentary about displaying truncation glyphs
6473 (produce_special_glyphs): Move here from term.c.
6475 * term.c (produce_special_glyphs): Move to xdisp.c.
6477 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
6480 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
6482 * xdisp.c (display_line): Avoid warning about implicit declaration
6485 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
6487 * lisp.h: Remove empty conditional.
6489 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
6491 * lread.c (load_path_check): Now static.
6493 Fix some minor --with-ns problems found by static checking.
6494 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
6495 (x_set_font) [!HAVE_X_WINDOWS]:
6496 * image.c (xpm_load_image) [HAVE_NS]:
6497 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
6498 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
6499 Remove unused local.
6500 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
6501 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
6502 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
6503 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
6504 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
6505 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
6506 Fix pointer signedness problem.
6507 * xfaces.c (FRAME_X_FONT_TABLE):
6508 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
6510 2012-07-07 Glenn Morris <rgm@gnu.org>
6512 * lread.c (load_path_check): New function, split from init_lread.
6513 (init_lread): Reorganize. Motivation:
6514 If EMACSLOADPATH is set, check/warn about that rather than the
6515 defaults, which we are not going to use. Hence we can remove
6516 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
6517 Don't warn if site-lisp directories are missing.
6518 If not installed, start from a blank load-path, since
6519 PATH_LOADSEARCH refers to the eventual installation directories.
6521 2012-07-07 Eli Zaretskii <eliz@gnu.org>
6523 Support truncation and continuation glyphs on GUI frames, when
6524 fringes are disabled. (Bug#11832)
6525 * xdisp.c (init_iterator): Get dimensions of truncation and
6526 continuation glyphs even if on GUI frames.
6527 Adjust it->last_visible_x on GUI frames when the left or right fringes,
6528 or both, are absent.
6529 (start_display, move_it_in_display_line_to): Handle the case of a
6530 GUI frame without a fringe to display continuation or truncation
6532 (insert_left_trunc_glyphs): Support GUI frames: make sure
6533 truncation glyphs overwrite enough glyphs from the current line to
6534 have sufficient space in pixels.
6535 (display_line): Support truncation and continuation glyphs on GUI
6536 frames. If some spare pixels are left on the line after inserting
6537 the truncation glyphs, fill that space with a stretch glyph of a
6538 suitably computed width.
6540 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
6541 produce_glyphs, to support GUI sessions.
6543 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
6545 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
6547 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
6549 Do not require float-time's arg to fit in time_t (Bug#11825).
6550 This works better on hosts where time_t is unsigned, and where
6551 float-time is applied to the (negative) difference between two times.
6552 * editfns.c (decode_time_components): Last arg is now double *,
6553 not int *, and means to store all the result as a double, without
6554 worrying about whether the seconds part fits in time_t.
6555 All callers changed.
6556 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
6557 All callers changed.
6558 (Ffloat_time): Do not fail merely because the specified time falls
6559 outside of time_t range.
6561 2012-07-07 Glenn Morris <rgm@gnu.org>
6563 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

6578 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
6579 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
6580 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.

6583 * xfont.c (compare_font_names): Redo to omit the need for casts.
6585 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
6587 * xfns.c (Fx_change_window_property): Doc fix.
6588 * w32fns.c (Fx_change_window_property): Doc fix.
6590 * w32fns.c (Fx_window_property): Accept the same arguments as the
6591 X Windows version. Doc fix.
6592 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
6594 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
6595 Eli Zaretskii <eliz@gnu.org>
6597 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
6598 Windows-specific code from nt/config.nt moved here.
6599 Obsolete settings removed.
6601 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6603 * process.c: Avoid unnecessary calls to gettime.
6604 (wait_reading_process_output): Don't get the time of day
6605 when gobbling data immediately and not waiting, as there's no need
6606 for it in that case. This removes a FIXME.
6608 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
6610 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
6611 is defined (Bug#11768).
6613 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6615 Fix marker debugging code.
6616 * marker.c (byte_char_debug_check): Do not perform the check
6617 if buffer is not multibyte.
6618 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
6619 Call byte_char_debug_check with correct arguments.
6621 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6623 Compile marker debugging code only if ENABLE_CHECKING is defined.
6624 * marker.c (byte_char_debug_check, count_markers):
6625 Use only if ENABLE_CHECKING is defined.
6626 (byte_debug_flag): Remove.
6627 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
6628 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
6630 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6632 Avoid code repetition in marker-related functions.
6633 * marker.c (attach_marker): New function.
6634 (Fset_marker, set_marker_restricted, set_marker_both)
6635 (set_marker_restricted_both): Use it.
6636 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
6637 Consistently rename charno to charpos.
6638 (marker_position): Add eassert.
6639 (marker_byte_position): Convert to eassert.

6658 * window.c (save_window_save): Likewise.
6660 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6662 Do not use Fdelete_overlay in delete_all_overlays
6663 to avoid redundant calls to unchain_overlay.
6664 * buffer.c (drop_overlay): New function.
6665 (delete_all_overlays, Fdelete_overlay): Use it.
6666 * minibuf.c (get_minibuffer): Fix comment.

6670 Port to OpenBSD 5.1 amd64.
6671 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
6672 This is needed for OpenBSD, and should be harmless on all BSD systems.
6673 Also, include <sys/sysctl.h>, as it should be available on all
6674 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
6675 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
6676 use p_pid member, not kp_proc.pid.
6678 2012-07-06 Glenn Morris <rgm@gnu.org>
6680 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
6682 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

6693 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
6695 Omit needless casts involving void * pointers and allocation.
6696 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
6697 as the former is more robust if P's type is changed.
6698 Prefer xzalloc to xmalloc + memset 0.
6699 Simplify malloc-or-realloc to realloc.
6700 Don't worry about xmalloc returning a null pointer.
6701 Prefer xstrdup to xmalloc + strcpy.
6702 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
6704 * keyboard.c (apply_modifiers_uncached): Prefer local array to
6705 alloca of a constant.

6710 hscroll is larger than the line width. Fixes long and futile
6711 looping inside extend_face_to_end_of_line (on a TTY) producing
6712 glyphs that are not needed and thrown away.
6714 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
6716 * marker.c (set_marker_restricted_both): Simplify by using

6742 * xdisp.c (window_hscroll_limited): New function.
6743 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
6744 coordinates when window's hscroll is set to insanely large
6747 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
6749 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

6810 * fileio.c (time_error_value): Check the right error number.
6811 Problem reported by Troels Nielsen in
6812 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
6814 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6816 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
6817 This should be fixed in a better way; see Eli Zaretskii in
6818 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
6819 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
6821 * fileio.c (time_error_value): Rename from special_mtime.
6822 The old name's problems were noted by Eli Zaretskii in
6823 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
6825 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
6826 This variable's comment says Emacs needs at least one GDB-visible
6827 symbol of type enum pvec_type, to work around GDB problems.
6828 The symbol's value doesn't matter.
6830 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
6831 that causes compilation to fail on pre-C99 compilers.
6833 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
6835 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
6836 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
6838 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6840 * buffer.c (init_buffer_once): Fix initialization of
6841 headers for buffer_defaults and buffer_local_symbols.
6842 Reported by Juanma Barranquero <lekktu@gmail.com>.
6844 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
6846 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
6847 * lisp.h (enum pvec_type): Use fewer bits.
6848 (PSEUDOVECTOR_SIZE_BITS): New constant.
6849 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
6850 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
6851 change in pvec_type.
6852 (PSEUDOVECTOR_TYPEP): New macro.
6853 (TYPED_PSEUDOVECTORP): Use it.
6854 * fns.c (internal_equal): Adapt code to extract pvectype.
6855 * emacs.c (gdb_pvec_type): Update type.
6856 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
6857 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
6858 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
6859 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
6860 (sweep_vectors): Use it. Use local var `total_bytes' instead of
6861 abusing vector->header.next.nbytes.
6862 (live_vector_p): Use PVEC_TYPE.
6863 (mark_object): Adapt code to extract pvectype. Use switch.
6865 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6867 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
6868 Tighten new eassert a bit.
6870 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6872 Fix compilation with --enable-gcc-warnings and -O1
6874 * doprnt.c (doprnt): Change type of tem to int, initialize
6875 to avoid compiler warning. Add eassert.
6876 * search.c (simple_search): Initialize match_byte to avoid
6877 compiler warning. Add eassert.
6879 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6881 Avoid weird behavior with large horizontal scrolls.
6882 Without this change, for example, large hscroll values would
6883 mess up Emacs's display on Fedora 15 x86, presumably due to
6884 overflows in int calculations in the display code.
6885 Also, if buffers had long lines, Emacs would freeze.
6886 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
6887 (set_window_hscroll): New function, containing the old guts of
6888 Fset_window_hscroll. Return the clipped value.
6889 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
6890 This avoids the need to check against PTRDIFF_MAX.
6892 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
6894 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6896 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
6898 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6900 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
6901 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
6902 since GCC 4.4.6 issues a bogus warning for them.
6904 Fix bugs in file timestamp newness comparisons.
6905 * fileio.c (Ffile_newer_than_file_p):
6906 * lread.c (Fload): Use full timestamp resolution of files,
6907 not just the 1-second resolution, so that files that are only
6908 slightly newer still count as newer.
6909 * fileio.c (Ffile_newer_than_file_p): Don't assume file
6910 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
6912 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
6914 * fileio.c: Improve handling of file time marker. (Bug#11852)
6915 (special_mtime): New function.
6916 (Finsert_file_contents, Fverify_visited_file_modtime):
6917 Use it to set special mtime values consistently.
6919 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
6921 * fileio.c (Finsert_file_contents): Properly handle st_mtime
6922 marker for non-existing file. (Bug#11852)
6924 2012-07-03 Glenn Morris <rgm@gnu.org>
6926 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
6927 and did not make it into globals.h).
6929 2012-07-03 Tom Tromey <tromey@redhat.com>
6931 * window.c (Fset_window_margins, Fset_window_fringes)
6932 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
6933 * textprop.c (Fprevious_property_change): No longer static.

6956 * intervals.h: Remove EXFUNs.
6957 * fontset.h: Remove EXFUN.

6962 * w32term.h: Remove EXFUNs.
6963 * window.h: Remove EXFUNs.

6965 * xterm.h: Remove EXFUN.
6967 2012-07-03 Glenn Morris <rgm@gnu.org>
6969 * lisp.h (Frandom): Make it visible to C.
6970 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
6971 buffer for invisible buffers. (Bug#1229)
6973 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6975 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
6976 values which aren't power of 2.
6977 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
6978 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
6981 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
6983 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
6985 * alloc.c (mark_object): Revert part of last patch to use `switch'.
6987 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6989 * alloc.c (allocate_vector_block): Remove redundant
6990 calls to mallopt if DOUG_LEA_MALLOC is defined.
6991 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
6992 avoid calls to mallopt if zero_vector is returned.
6994 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6996 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
6997 is enabled, avoid dereferencing NULL current_sblock if
7000 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7002 Cleanup basic buffer management.
7003 * buffer.h (struct buffer): Change layout to use generic vector
7004 marking code. Fix some comments. Change type of 'clip_changed'
7005 to bitfield. Remove unused #ifndef old.
7006 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
7007 (GET_OVERLAYS_AT): Fix indentation.
7008 (for_each_per_buffer_object_at): New macro.
7009 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

7012 * alloc.c (allocate_buffer): Adjust to match new layout of
7013 struct buffer. Fix comment.
7014 (mark_overlay): New function.

7016 Lisp area of struct buffer.
7017 (mark_object): Use it. Adjust marking of misc objects
7018 and related comments.
7020 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
7022 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
7023 wrapper that is not needed because the wrapped code is a no-op (zero
7024 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
7025 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
7027 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
7029 * alloc.c (mark_buffer): Simplify. Remove prototype.
7030 (mark_object): Add comment. Reorganize marking of vector-like
7031 objects. Use CHECK_LIVE for all vector-like objects except buffers
7032 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
7033 Avoid redundant calls to mark_vectorlike for bool vectors.
7035 2012-06-30 Glenn Morris <rgm@gnu.org>
7037 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
7039 * epaths.in (PATH_SITELOADSEARCH): New.
7040 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
7041 This is rather than relying on --enable-locallisppath elements
7042 having "site-lisp" in their names. (Bug#10208#25, 11658)
7044 2012-06-30 Eli Zaretskii <eliz@gnu.org>
7046 * w32proc.c (sys_select): Accept and ignore one more argument.
7048 * w32.c (emacs_gnutls_pull): Call select with one more argument.
7050 * sysselect.h [DOS_NT]: Don't include sys/select.h.
7051 (pselect) [!MS_DOS]: Redirect to sys_select.
7053 * sysdep.c: Don't include dos.h and dosfns.h.
7055 * process.c (sys_select):
7056 * msdos.c (sys_select): Accept one more argument and ignore it.
7058 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
7059 adapt data types and code to that.
7062 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
7063 which clashes with the gnulib function of the same name.
7065 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
7067 * font.c (font_style_to_value, font_style_symbolic)
7068 (font_prop_validate_style): Add type checks for values in
7071 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
7073 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
7076 2012-06-29 Eli Zaretskii <eliz@gnu.org>
7078 * xdisp.c (try_window_id): Undo last change.
7080 * w32.c (getwd): Adjust commentary about startup_dir.
7081 (init_environment): Always call sys_access, even in non-MSVC
7082 builds. Don't chdir to the directory of the Emacs executable.
7083 This undoes code from 1997 which was justified by the need to
7084 "avoid conflicts when removing and renaming directories". But its
7085 downside was that every relative file name was being interpreted
7086 relative to the directory of the Emacs executable, which can never
7087 be TRT. In particular, it broke sys_access when called with
7088 relative file names.
7089 (sys_access): Map GetLastError to errno.
7091 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
7093 * window.h (struct window): Change type of 'fringes_outside_margins'

7097 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
7100 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
7102 * gnutls.c (emacs_gnutls_handshake):
7103 Add QUIT to make the loop interruptible.
7105 2012-06-29 Glenn Morris <rgm@gnu.org>
7107 * charset.c (init_charset): Make lack of etc/charsets fatal.
7109 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
7111 * editfns.c (region_limit): Fix type mismatch.
7113 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

7116 undefined. Convert from xassert to eassert.
7117 * nsmenu.m: Convert from xassert to eassert.
7118 * nsterm.m: Likewise.
7120 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
7122 * editfns.c (region_limit): Clip to narrowing (bug#11770).
7124 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
7126 Avoid integer overflow on scroll-left and scroll-right.
7127 * window.c (HSCROLL_MAX): New macro.
7128 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
7129 overflow when requested scroll falls outside ptrdiff_t range.
7131 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
7133 * window.h (struct window): Change type of 'hscroll',
7134 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
7135 'last_modified' and 'last_overlay_modified' to EMACS_INT.
7136 Adjust users accordingly.
7137 * xdisp.c (try_cursor_movement): Replace type check with eassert.
7138 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
7139 from EMACS_INT to ptrdiff_t.
7140 (make_window): Omit redundant initialization.
7142 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
7144 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
7146 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
7148 * window.h (struct window): Change type of 'use_time' and
7149 'sequence_number' from Lisp_Object to int.
7150 * frame.c (make_frame): Adjust users accordingly.
7151 * print.c (print_object): Likewise.
7152 * window.c (select_window, Fwindow_use_time, make_parent_window)
7153 (make_window): Likewise.

7158 enabled with --enable-checking=[all,glyphs] configure option.
7159 Fix GLYPH_DEBUG usage assuming that it may be undefined,
7160 adjust comments accordingly.

7211 avoid GCC warning about unused macro.
7213 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
7215 * alloc.c (allocate_string): Omit intervals initialization.
7216 * alloc.c (make_uninit_multibyte_string): Initialize intervals
7217 as in make_pure_string and make_pure_c_string.
7219 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
7221 * alloc.c (allocate_string): Fix last change.
7223 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

7273 * alloc.c: Remove build_string.
7274 * lisp.h: Define build_string as static inline. This provides
7275 a better opportunity to optimize away calls to strlen when the
7276 function is called with compile-time constant argument.

7281 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
7283 Use sprintf return value instead of invoking strlen on result.
7284 In the old days this wasn't portable, since some sprintf
7285 implementations returned char *. But they died out years ago and
7286 Emacs already assumes sprintf returns int.
7287 Similarly for float_to_string.
7288 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
7289 * ccl.c (ccl_driver):
7290 * character.c (string_escape_byte8):

7293 * print.c (print_object):
7294 * xdisp.c (message_dolog):
7295 * xfns.c (syms_of_xfns):
7296 Use sprintf or float_to_string result to avoid need to call strlen.
7297 * data.c (Fnumber_to_string):
7298 Use make_unibyte_string, since the string must be ASCII.
7299 * lisp.h, print.c (float_to_string): Now returns int length.
7300 * term.c (produce_glyphless_glyph):
7301 Use sprintf result rather than recomputing it.
7303 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
7304 * Makefile.in (ALL_CFLAGS):
7305 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
7306 * gmalloc.c, regex.c: Include <config.h> unconditionally.
7308 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
7310 * dispextern.h (xstrcasecmp): Define to library function
7311 strcasecmp if available.

7332 * xfns.c (x_window): Remove redundant cast.
7334 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
7336 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
7337 `const char *' to `char *' to avoid compiler warning.
7339 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
7341 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
7342 instead of truncating it to 63 (admittedly a generous limit).
7344 * process.c: Fix spelling and caps in comments.
7346 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
7348 * emacs.c (setpgrp): Remove definition, unused.

7394 * sound.c (sound_warning, parse_sound):
7395 Remove unnecessary forward decls.
7397 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
7399 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
7400 * lisp.h (WAIT_READING_MAX): New macro.
7401 * dispnew.c (Fsleep_for, sit_for):
7402 * keyboard.c (kbd_buffer_get_event):
7403 * process.c (Faccept_process_output):
7404 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
7405 This improves on the previous patch, which introduced a bug
7406 when time_t is unsigned and as wide as intmax_t.
7407 See <http://bugs.gnu.org/9000#51>.
7409 2012-06-23 Eli Zaretskii <eliz@gnu.org>
7411 * dispnew.c (sit_for, Fsleep_for):
7412 * keyboard.c (kbd_buffer_get_event):

7425 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
7426 Privately reported by Herbert J. Skuhra.
7427 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
7429 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
7430 not make_lisp_timeval, when the argument is of type EMACS_TIME.
7432 2012-06-23 Eli Zaretskii <eliz@gnu.org>
7434 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
7435 last argument of make_unibyte_string.
7437 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
7438 language ID in the event parameters.
7440 * w32term.c (w32_read_socket): Put the new keyboard codepage into
7441 event.code, not the obscure "character set ID".

7464 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
7465 Privately reported by Herbert J. Skuhra.
7466 [__FreeBSD__]: Remove "*/" typo after "#include".

7468 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.
7469 (TIMEVAL, system_process_attributes) [__FreeBSD__]:
7470 Don't assume EMACS_TIME and struct timeval are the same type.
7472 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
7474 Support higher-resolution time stamps (Bug#9000).
7475 The time stamps are only nanosecond-resolution at the C level,
7476 since that's the best that any real-world system supports now.
7477 But they are picosecond-resolution at the Lisp level, as that's
7478 easy, and leaves room for future OS improvements.
7480 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
7483 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
7484 Don't get current time unless it's needed.
7486 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
7487 now provides it if it's absent.
7488 (start_atimer): Port to higher-res time stamps.
7489 Check for time stamp overflow. Don't get current time more
7490 often than is needed.
7492 * buffer.h (struct buffer): Buffer modtime now has high resolution.
7493 Include systime.h, not time.h.
7494 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
7496 * dired.c: Include stat-time.h.
7497 (Ffile-attributes): File times now have higher resolution.
7499 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
7500 (struct image): Timestamp now has higher resolution.
7502 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
7503 has at least microseconds now. All uses removed.
7504 (update_frame, update_single_window, update_window, update_frame_1)
7505 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
7506 (duration_to_sec_usec): Remove; no longer needed.
7508 * editfns.c (time_overflow): Now extern.
7509 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
7510 (float-time, Fformat_time_string, Fcurrent_time_string)
7511 (Fcurrent_time_zone): Accept and generate higher-resolution
7513 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
7514 (decode_time_components, lisp_seconds_argument): New functions.
7515 (make_time): Now static.
7516 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
7517 Report an error if the time is invalid, rather than having the caller
7520 * fileio.c: Include <stat-time.h>
7521 (Fcopy_file): Copy higher-resolution time stamps.
7522 Prefer to set the time stamp via a file descriptor if that works.
7523 (Fset_file_times, Finsert_file_contents, Fwrite_region)
7524 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
7525 (Fvisited_file_modtime, Fset_visited_file_modtime):
7526 Support higher-resolution time stamps.
7528 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
7530 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
7532 * image.c (prepare_image_for_display, clear_image_cache)
7533 (lookup_image): Port to higer-resolution time stamps.
7535 * keyboard.c (start_polling, bind_polling_period):
7536 Check for time stamp overflow.
7537 (read_char, kbd_buffer_get_event, timer_start_idle)
7538 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
7539 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
7540 Port to higher-resolution time stamps. Do not assume time_t is signed.
7541 (decode_timer): New function. Timers are now vectors of length 9,
7542 not 8, to accommodate the picosecond component.
7543 (timer_check_2): Use it.
7545 * nsterm.m (select_timeout, timeval_subtract): Remove.
7546 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
7547 as they're a bit more accurate and handle overflow better.
7548 (ns_select): Change prototype to be compatible with pselect.
7549 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
7550 * nsterm.h (ns_select): Adjust prototype.
7552 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
7553 us-resolution time stamps.
7554 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
7556 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
7558 * lisp.h (time_overflow): New decl.
7559 (wait_reading_process_output): First arg is now intmax_t, not int,
7560 to accommodate larger waits.
7562 * process.h (struct Lisp_Process.read_output_delay):
7563 Now counts nanoseconds, not microseconds.
7564 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
7566 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
7567 (wait_reading_process_output):
7568 Port to ns-resolution time stamps.
7569 (Faccept_process_output, wait_reading_process_output):
7570 Check for time stamp overflow. Do not assume time_t is signed.
7571 (select_wrapper): Remove; we now use pselect.
7572 (Fprocess_attributes): Now generates ns-resolution time stamps.
7574 * sysdep.c: Include utimens.h. Don't include utime.h
7575 or worry about struct utimbuf; gnulib does that for us now.
7576 (gettimeofday): Remove; gnulib provides a substitute.
7577 (make_timeval): New function.
7578 (set_file_times): Now sets ns-resolution time stamps.
7579 New arg FD; all uses changed.
7580 (time_from_jiffies, ltime_from_jiffies, get_up_time)
7581 (system_process_attributes):
7582 Now returns ns-resolution time stamp. All uses changed.
7583 Check for time stamp overflow.
7585 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
7586 provides a substitute now.
7588 * systime.h: Include timespec.h rather than sys/time.h and time.h,
7589 since it guarantees struct timespec.
7590 (EMACS_TIME): Now struct timespec, so that we can support
7591 ns-resolution time stamps.
7592 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
7593 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
7594 (EMACS_USECS): Remove.
7595 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
7596 so multiply the arg by 1000 before storing it.
7597 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
7599 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
7600 Port to ns-resolution time stamps.
7601 (EMACS_TIME_NEG_P): Remove; replaced by....
7602 (EMACS_TIME_SIGN): New macro.
7603 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
7604 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
7605 (set_file_times, make_time, lisp_time_argument): Adjust signature.
7606 (make_timeval, make_lisp_time, decode_time_components): New decls.
7607 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
7608 that it mishandled time_t overflow. You can't compare by subtracting!
7609 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
7610 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
7612 * term.c: Include <sys/time.h>.
7613 (timeval_to_Time): New function, for proper overflow wraparound.

7616 * undo.c (record_first_change): Support higher-resolution time stamps
7618 (Fprimitive_undo): Use them when restoring time stamps.
7620 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
7621 (w32_get_internal_run_time):
7622 Port to higher-resolution Emacs time stamps.
7623 (ltime): Now accepts single 64-bit integer, as that's more convenient
7626 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
7628 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
7629 for compatibility with pselect. Support ns-resolution time stamps.
7631 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
7633 * xselect.c (wait_for_property_change, x_get_foreign_selection):
7634 Check for time stamp overflow, and support ns-resolution time stamps.
7636 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
7637 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
7638 (timeval_subtract): Remove; no longer needed.
7639 (XTflash, XTring_bell, x_wait_for_event):
7640 Port to ns-resolution time stamps. Don't assume time_t is signed.
7642 2012-06-22 Chong Yidong <cyd@gnu.org>
7644 * xdisp.c (x_consider_frame_title): Revert last change.
7646 2012-06-22 Eli Zaretskii <eliz@gnu.org>
7648 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
7649 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
7650 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
7651 staticidx goes up to 1597 out of 1600 = 0x640.)
7653 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
7655 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
7656 Otherwise, the umask might be mistakenly 0 while handling input signals.
7658 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
7660 * minibuf.c (Fread_string): Bind minibuffer-completion-table.
7662 2012-06-19 Dmitry Antipov <dmantipov@yandex.ru>

7665 * font.c, image.c, keyboard.c, lread.c, menu.c, minibuf.c, msdos.c:
7666 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
7667 access to `contents' member of Lisp_Vector objects with AREF and ASET
7670 2012-06-19 Chong Yidong <cyd@gnu.org>
7672 * frame.c (delete_frame): When selecting a frame on a different
7673 text terminal, do not alter the terminal's top-frame.

7676 frame's selected window and its terminal's top-frame.
7677 (unwind_format_mode_line): Restore them.
7678 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
7680 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
7681 since tty frames can be explicitly named.
7682 (prepare_menu_bars): Likewise.
7684 * term.c (Ftty_top_frame): New function.
7686 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
7688 Port byte-code-meter to modern targets.
7689 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
7690 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
7691 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
7692 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
7693 (METER_1, METER_2): Simplify.
7695 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
7697 * data.c (Fdefalias): Return `symbol' (bug#11686).
7699 2012-06-18 Martin Rudalics <rudalics@gmx.at>
7701 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
7702 gets killed during executing of this function (Bug#11665).
7703 Try to always return Qt when the buffer has been actually killed.
7704 (Vkill_buffer_query_functions): In doc-string say that functions
7705 run by this hook should not change the current buffer.
7707 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
7709 Fix recently-introduced process.c problems found by static checking.
7710 * process.c (write_queue_push, write_queue_pop, send_process):
7711 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.
7712 (write_queue_pop): Fix pointer signedness problem.
7713 (send_process): Remove unused local.
7715 2012-06-17 Chong Yidong <cyd@gnu.org>
7717 * xdisp.c (redisplay_internal): No need to redisplay terminal
7718 frames that are not on top.
7720 2012-06-17 Troels Nielsen <bn.troels@gmail.com>
7722 * process.c (make_process): Initialize write_queue.
7723 (write_queue_push, write_queue_pop): New functions.
7724 (send_process): Use them to maintain correct ordering of process
7727 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
7729 * lisp.h (eassert): Assume C89 or later.
7730 This removes the need for CHECK.
7731 (CHECK): Remove. Its comments about always evaluating its
7732 argument were confusing, as 'eassert' typically does not evaluate
7735 * coding.c (produce_chars): Use ptrdiff_t, not int.
7737 * xterm.c (x_draw_underwave): Check for integer overflow.
7738 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.
7740 2012-06-17 Jan Djärv <jan.h.d@swipnet.se>

7923 code works fine either way, and efficiency is not a concern here,
7924 as the union type is for debugging, not for production.
7925 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
7926 Use an inline function on all platforms when using the union type,
7927 since this is simpler and 'static inline' can be used portably
7929 (LISP_INITIALLY_ZERO): New macro.

8071 * doprnt.c (doprnt): Truncate multibyte char correctly.
8072 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
8073 would mishandle a string argument "Xc" if X was a multibyte

8075 rather than including all of X.

8158 and 'double' in a couple of places.
8160 2012-05-31 Eli Zaretskii <eliz@gnu.org>
8162 * xdisp.c (handle_stop): Detect whether we have overlay strings
8163 loaded by testing it->current.overlay_string_index to be
8164 non-negative, instead of checking whether n_overlay_strings is
8165 positive. (Bug#11587)

8177 maybe_unify_char, which was the cause of relocation of buffer text
8180 2012-05-31 Eli Zaretskii <eliz@gnu.org>
8182 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
8183 for the duration of call to load_charset, to avoid problems with
8184 callers of maybe_unify_char that access buffer text through C
8187 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
8188 decrement the inhibition flag, instead of just setting or

8194 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.

8198 (gray_bitmap_bits): Remove; no longer needed.

8240 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
8242 Do not create empty overlays with the evaporate property (Bug#9642).
8243 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
8244 Bug#9642, but explicitly check that the buffer the overlay would
8245 be moved to is live and rearrange lines to make sure that errors
8246 will not put the overlay in an inconsistent state.
8247 (Fdelete_overlay): Cosmetics.
8249 2012-05-28 Eli Zaretskii <eliz@gnu.org>
8251 * w32term.c (my_bring_window_to_top): New function.
8252 (x_raise_frame): Use handle returned by DeferWindowPos, which
8253 could be different from the original one.

8257 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
8258 by calling BringWindowToTop.
8260 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
8261 (WM_EMACS_END): Increase by one.
8263 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
8265 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
8266 This avoids undefined behavior that might cause the eassert
8267 to not catch an out-of-range value.
8269 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
8271 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
8272 Update dependencies.
8274 2012-05-27 Eli Zaretskii <eliz@gnu.org>

8281 when referring to sectname field in printf format.
8283 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
8285 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
8286 Only r_alloc_inhibit_buffer_relocation needed to be added;
8287 the others were already declared.
8289 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
8290 before checking whether it's out of range. Put the check inside
8292 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
8294 2012-05-27 Ken Brown <kbrown@cornell.edu>
8296 * callproc.c (Fcall_process): Restore a line that was accidentally
8297 commented out in the 2011-02-13 change (bug#11547).
8299 2012-05-27 Eli Zaretskii <eliz@gnu.org>
8301 * lisp.h [REL_ALLOC]: Add prototypes for external functions
8302 defined on ralloc.c.
8304 * buffer.c [REL_ALLOC]: Remove prototypes of
8305 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
8306 they are now on lisp.h.
8308 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
8310 * search.c (search_buffer): Use it to inhibit relocation of buffer
8311 text while re_search_2 is doing its job, because re_search_2 is
8312 passed C pointers to buffer text. (Bug#11519)
8314 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
8317 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
8318 state after an additional call to move_it_in_display_line_to, keep
8319 the values of it->max_ascent and it->max_descent found for the
8321 (pos_visible_p): Revert the comparison against bottom_y to what it
8322 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
8325 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
8327 Fix coding-related core dumps with gcc -ftrapv.
8328 The code was computing A - B, where A and B are pointers, and B is
8329 random garbage. This can lead to core dumps on platforms that
8330 have special pointer registers, and it also leads to core dumps on
8331 x86-64 when compiled with gcc -ftrapv. The fix is to compute
8332 A - B only when B is initialized properly.
8333 * coding.c (coding_set_source, coding_set_destination): Return void.
8334 (coding_change_source, coding_change_destinations): New functions,
8335 with the old behaviors of coding_set_source and coding_set_destination.
8336 All callers that need an offset changed to use these new functions.
8338 2012-05-26 Glenn Morris <rgm@gnu.org>
8340 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
8342 2012-05-26 Eli Zaretskii <eliz@gnu.org>
8344 Extend mouse support on W32 text-mode console.
8345 * xdisp.c (draw_row_with_mouse_face):
8346 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
8348 * w32console.c: Include window.h.
8349 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
8351 (initialize_w32_display): Initialize mouse-highlight data.
8353 * w32inevt.c: Include termchar.h and window.h.
8354 (do_mouse_event): Support mouse-autoselect-window. When the mouse
8355 moves, call note_mouse_highlight. If help_echo changed, call
8356 gen_help_event to produce help-echo message in the echo area.
8357 Call clear_mouse_face if mouse_face_hidden is set in the mouse
8360 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
8362 * lread.c (read1): Simplify slightly to avoid an overflow warning
8363 with GCC 4.7.0 on x86-64.
8365 2012-05-26 Eli Zaretskii <eliz@gnu.org>
8367 * bidi.c (bidi_mirror_char): Revert last change: an int is
8368 definitely wide enough here.
8370 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
8372 Fix integer width and related bugs (Bug#9874).

8379 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
8380 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
8382 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8383 (allocate_pseudovector):
8384 Use int, not EMACS_INT, where int is wide enough.
8385 (inhibit_garbage_collection, Fgarbage_collect):
8386 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
8387 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
8388 int might not be wide enough.
8389 (bidi_cache_search, bidi_cache_find, bidi_init_it)

8392 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
8393 (bidi_level_of_next_char, bidi_move_to_visually_next):
8394 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8395 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
8396 (Fkill_buffer, Fset_buffer_major_mode)
8397 (advance_to_char_boundary, Fbuffer_swap_text)

8402 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
8403 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
8404 (Foverlay_recenter, last_overlay_modification_hooks_used)
8405 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
8406 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8407 (validate_region): Omit unnecessary test for b <= e,
8408 since that's guaranteed by the previous test.
8409 (adjust_overlays_for_delete): Avoid pos + length overflow.
8410 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
8411 (report_overlay_modification):
8412 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
8413 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
8414 Omit pointer cast, which isn't needed anyway, and doesn't work
8415 after the EMACS_INT -> ptrdiff_t change.
8416 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
8417 * buffer.h: Adjust decls to match defn changes elsewhere.

8422 not int, to avoid needless 32-bit limit on 64-bit hosts.
8423 (exec_byte_code): Use tighter memory-full test, one that checks
8424 for alloca overflow. Don't compute the address of the object just
8425 before an array, as that's not portable. Use EMACS_INT, not
8426 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
8427 * callint.c (Fcall_interactively):
8428 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
8429 * callproc.c (call_process_kill, Fcall_process):

8439 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
8440 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8441 (casify_object): Avoid integer overflow when overallocating buffer.
8442 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
8443 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
8444 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
8445 * category.h (CATEGORYP): Don't assume arg is nonnegative.
8446 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
8447 integers are now checked earlier. All uses replaced with XINT.
8449 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8450 For CCL_MapSingle, check that content and value are in int range.
8451 (ccl_driver, Fregister_code_conversion_map):
8452 Check that Vcode_version_map_vector is a vector.
8453 (resolve_symbol_ccl_program): Check that vector header is in range.
8454 Always copy the vector, so that we can check its contents reliably
8455 now rather than having to recheck each instruction as it's being
8456 executed. Check that vector words fit in 'int'.
8457 (ccl_get_compiled_code, Fregister_ccl_program)
8458 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
8459 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
8460 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
8461 contents are in range.
8462 (Fccl_execute_on_string): Check that status is in range.
8463 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
8464 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
8465 Accept and return EMACS_INT, not int, because callers can pass values
8467 (c_string_width, strwidth, lisp_string_width, chars_in_text)

8470 (str_as_unibyte, str_to_unibyte, string_count_byte8)
8471 (string_escape_byte8, Fget_byte):
8472 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8473 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
8474 avoid mishandling large integers.
8475 * character.h: Adjust decls to match defn changes elsewhere.

8484 (Fdefine_charset_internal): Check ranges here, more carefully.
8485 Don't rely on undefined behavior with signed left shift overflow.
8486 Don't assume unsigned int fits into fixnum, or that fixnum fits
8487 into unsigned int. Don't require max_code to be a valid fixnum;
8488 that's not true for gb10830 4-byte on a 32-bit host. Allow
8489 invalid_code to be a cons, for the same reason. Require code_offset
8490 to be a character. Avoid int overflow if max_char is close
8492 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
8493 this is intended anyway and avoids some undefined behavior.
8494 (load_charset_map): Pass unsigned, not int, as 2nd arg of
8495 INDEX_TO_CODE_POINT, as that's what it expects.
8496 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
8497 * charset.h (DECODE_CHAR): Return int, not unsigned;
8498 this is what was intended anyway, and it avoids undefined behavior.
8499 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
8500 integer-overflow issues.
8501 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
8502 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
8503 where the argument is EMACS_INT, and this behavior is not intended.
8504 * chartab.c (Fmake_char_table, Fset_char_table_range)
8505 (uniprop_get_decoder, uniprop_get_encoder):
8506 Don't assume fixnum fits in int.
8507 * cmds.c (move_point): New function, that does the gist of
8508 Fforward_char and Fbackward_char, but does so while checking
8509 for integer overflow more accurately.
8510 (Fforward_char, Fbackward_char): Use it.
8511 (Fforward_line, Fend_of_line, internal_self_insert)
8512 (internal_self_insert):
8513 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8514 Fix a FIXME, by checking for integer overflow when calculating
8515 target_clm and actual_clm.

8547 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
8548 (consume_chars): Rewrite to not calculate an address outside buffer.
8549 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
8550 Don't access memory outside of the args array.
8551 (Fdefine_coding_system_internal): Check for charset-id overflow.
8552 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
8553 result of ENCODE_CHAR.

8572 * data.c (let_shadows_buffer_binding_p, let_shadows_global_binding_p):
8573 Do not attempt to compute the address of the object just before a
8574 buffer; this is not portable.

8577 (Faset): Use int, not EMACS_INT, where int is wide enough.
8578 (Fstring_to_number): Don't assume fixnums fit in int.

9312 already have overlays loaded.
9313 (handle_single_display_spec): Before returning without displaying
9314 fringe bitmap, synchronize the bidi iterator with the main display
9315 iterator, by calling iterate_out_of_display_property.

9317 testing that it->string is a Lisp string.
9318 (get_next_display_element): When the current object is exhausted,

9324 the display vector. (Bug#11417)
9325 (pos_visible_p): Don't report a position visible when move_it_to

9331 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
9332 and right-margin display specs even if the spec is invalid or we
9333 are on a TTY, and thus unable to display on the fringes.
9334 That's because the text with the property will not be displayed anyway,
9335 so we need to signal to the caller that this is a "replacing"
9336 display spec. This fixes display when the spec is invalid or we
9339 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
9341 * unexaix.c (make_hdr): Fix typo in prototype.
9342 This bug broke the build on AIX. Problem reported by Gilles Pion.

9351 * ns.mk: Update for ns_appbindir no longer having trailing "/".
9353 2012-05-12 Eli Zaretskii <eliz@gnu.org>
9355 * lisp.mk (lisp): Add newcomment.elc.
9357 2012-05-12 Glenn Morris <rgm@gnu.org>
9359 * Makefile.in (MKDIR_P): New, set by configure.
9360 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
9362 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
9364 Remove unused function hourglass_started.
9365 * dispextern.h (hourglass_started):
9366 * w32fns.c (hourglass_started):
9367 * xdisp.c (hourglass_started): Remove.
9369 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
9371 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
9372 Update dependencies.
9374 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
9376 * xgselect.c (xg_select): Put maxfds+1 into a var.
9377 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
9379 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
9381 2012-05-10 Dave Abrahams <dave@boostpro.com>
9383 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
9384 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
9386 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
9388 * dbusbind.c (xd_registered_buses): New internal Lisp object.
9389 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
9390 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
9391 Initialize xd_registered_buses.
9393 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
9395 Untag more efficiently if USE_LSB_TAG.
9396 This is based on a proposal by YAMAMOTO Mitsuharu in
9397 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
9398 For an admittedly artificial (nth 8000 longlist) benchmark on
9399 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
9400 Emacs's overall text size by 1%.
9401 * lisp.h (XUNTAG): New macro.
9402 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
9403 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
9404 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
9405 * eval.c (Fautoload):
9406 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
9407 * frame.h (XFRAME): Use XUNTAG.
9409 Port recent dbusbind.c changes to 32-bit --with-wide-int.
9410 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
9411 Remove unportable assumptions about print widths of types like
9413 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
9414 intptr_t when converting between pointer and integer, to avoid GCC
9415 warnings about wrong width.
9417 2012-05-09 Eli Zaretskii <eliz@gnu.org>
9419 * w32proc.c (new_child): Force Windows to reserve only 64KB of
9420 stack for each reader_thread, instead of defaulting to 8MB
9421 determined by the linker. This avoids failures in creating
9422 subprocesses on Windows 7, see the discussion in this thread:
9423 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
9425 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
9427 Fix up display of the *Minibuf-0* buffer in the mini window.
9428 * keyboard.c (read_char): Don't clear the echo area if there's no
9430 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
9431 contents of *Minibuf-0*) if there's no message displayed in its stead.
9433 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
9435 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
9438 2012-05-06 Chong Yidong <cyd@gnu.org>
9440 * lisp.mk (lisp): Update.
9442 2012-05-05 Jim Meyering <meyering@redhat.com>
9444 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
9446 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
9448 * data.c (PUT_ERROR): New macro.
9449 (syms_of_data): Use it. Add new error type `user-error'.
9450 * undo.c (user_error): New function.
9451 (Fprimitive_undo): Use it.
9452 * print.c (print_error_message): Adjust print style for `user-error'.
9453 * keyboard.c (user_error): New function.
9454 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
9456 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
9458 Do not limit current-time-string to years 1000..9999.
9459 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
9460 (Fcurrent_time_string): Support any year that is supported by the
9461 underlying localtime representation. Don't use asctime, as it
9462 has undefined behavior for years outside the range -999..9999.
9464 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
9466 Fix race conditions involving setenv, gmtime, localtime, asctime.
9467 Without this fix, interrupts could mess up code that uses these
9468 nonreentrant functions, since setting TZ invalidates existing
9469 tm_zone or tzname values, and since most of these functions return
9470 pointers to static storage.
9471 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
9472 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
9473 Grow the critical sections to include not just invoking
9474 localtime/gmtime, but also accessing these functions' results
9475 including their tm_zone values if any, and any related TZ setting.
9476 (format_time_string): Last arg is now struct tm *, not struct tm **,
9477 so that the struct tm is saved in the critical section.
9478 All callers changed. Simplify allocation of initial buffer, partly
9479 motivated by the fact that memory allocation needs to be outside
9480 the critical section.
9482 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
9484 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
9485 with RESET_INTERVAL.
9487 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
9488 Remove duplicated buffer name initialization.
9490 2012-05-02 Jim Meyering <jim@meyering.net>
9492 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
9494 * xfns.c (x_window): Use xstrdup (Bug#11375).
9496 2012-05-02 Eli Zaretskii <eliz@gnu.org>
9498 * xdisp.c (pos_visible_p): If already at a newline from the
9499 display string before the 'while' loop, don't walk back the glyphs
9500 from it3.glyph_row. Solves assertion violation when the display
9501 string begins with a newline (egg.el). (Bug#11367)
9503 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
9505 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
9508 2012-05-01 Glenn Morris <rgm@gnu.org>
9510 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
9511 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
9512 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
9513 All were removed before 23.1.
9515 * dispnew.c: Remove HAVE_LIBNCURSES test;
9516 it is always true on relevant platforms.
9518 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
9519 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
9521 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
9523 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
9525 * .gdbinit (xpr): Remove checks for no longer existing misc types.
9526 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
9529 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
9531 Do not avoid creating empty evaporating overlays (Bug#9642).
9532 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
9533 That is, do not delete an evaporating overlay if it becomes
9534 empty after its bounds are adjusted to fit within its buffer.
9535 This fix caused other problems, and I'm reverting it until we get
9536 to the bottom of them.
9538 2012-04-27 Chong Yidong <cyd@gnu.org>
9540 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
9542 2012-04-27 Eli Zaretskii <eliz@gnu.org>
9544 * xdisp.c (pos_visible_p): If the window start position is beyond
9545 ZV, start the display from buffer beginning. Prevents assertion
9546 violation in init_iterator when the minibuffer window is scrolled
9549 * window.c (window_scroll_pixel_based): Likewise.
9551 2012-04-27 Chong Yidong <cyd@gnu.org>
9553 * keymap.c (where_is_internal): Doc fix (Bug#10872).
9555 2012-04-27 Glenn Morris <rgm@gnu.org>
9557 * fileio.c (Fcopy_file, Fset_file_selinux_context):
9558 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
9560 2012-04-27 Eli Zaretskii <eliz@gnu.org>
9562 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
9563 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
9565 2012-04-26 Eli Zaretskii <eliz@gnu.org>
9567 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
9568 display element, check also the underlying string or buffer
9569 character. (Bug#11341)
9571 * w32menu.c: Include w32heap.h.
9572 (add_menu_item): If the call to AppendMenuW (via
9573 unicode_append_menu) fails, disable Unicode menus only if we are
9574 running on Windows 9X/Me.
9576 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
9578 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
9579 (xgetint): Add missing shift for LSB tags.
9581 2012-04-24 Martin Rudalics <rudalics@gmx.at>
9583 * keyboard.c (read_char): Don't wipe echo area for select window
9584 events: These might get delayed via `mouse-autoselect-window'
9587 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
9589 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
9590 manipulation of :loaded-from data.
9592 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
9594 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
9595 now a cons (bug#11311).
9597 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
9599 Do not create empty overlays with the evaporate property (Bug#9642).
9600 * buffer.c (Fmove_overlay): Delete an evaporating overlay
9601 if it becomes empty after its bounds are adjusted to fit within
9602 its buffer. Without this fix, in a nonempty buffer (let ((o
9603 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
9604 yields an empty overlay that has the evaporate property, which is
9605 not supposed to happen.
9607 Fix minor GTK3 problems found by static checking.
9608 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
9609 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
9610 (struct _EmacsFixedClass, emacs_fixed_get_type):

9618 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
9619 (EMACS_FIXED_GET_CLASS): Remove; unused.
9620 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
9622 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
9623 Problem reported by Juanma Barranquero for Windows -Wunused-function.
9625 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
9627 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
9628 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
9629 (__malloc_size_t, __malloc_ptrdiff_t):
9630 Remove. All uses removed, replaced by the definiens if needed,
9631 since we can assume C89 or better now.
9632 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
9633 (protect_malloc_state, align, get_contiguous_space)
9634 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)
9635 (malloc_atfork_handler_child, malloc_enable_thread)

9640 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
9641 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
9642 Define using prototypes, not old style.
9643 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
9644 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
9645 (align): Don't assume that signed integer overflow wraps around.
9646 Omit unused local var.
9647 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
9648 (_free_internal_nolock, memalign, mallochook, reallochook):
9649 Omit no-longer-needed casts.
9650 (valloc): Use getpagesize, not __getpagesize.

9652 (struct hdr): The 'magic' member is now size_t, not unsigned long.
9654 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
9656 2012-04-22 Michael Albinus <michael.albinus@gmx.de>

9704 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
9705 Do not assume ptrdiff_t is the same width as 'int'.
9707 * alloc.c: Handle unusual debugging option combinations.
9708 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
9709 since the two debugging options are incompatible.
9710 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS

9722 * sysdep.c [__FreeBSD__]: Minor cleanups.
9723 (list_system_processes, system_process_attributes) [__FreeBSD__]:
9724 Use Emacs indenting style more consistently. Avoid some casts.
9725 Use 'double' consistently rather than mixing 'float' and 'double'.
9727 2012-04-21 Eduard Wiebe <usenet@pusto.de>
9729 * sysdep.c (list_system_processes, system_process_attributes):

9764 row, return zero immediately.
9765 (try_cursor_movement): If inside continuation line, don't back up
9766 farther than the first row after the header line, if any.
9767 Don't consider the header-line row as "partially visible", even if
9768 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
9770 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

9807 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
9808 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
9809 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
9810 (NEED_MEM_INSERT): New macro.
9811 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
9812 Remove one incorrect comment and fix another.

9826 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
9827 Remove decls. This fixes an "It stinks!".
9829 * alloc.c (which_symbols): Fix alignment issue / type clash.
9831 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
9833 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

9846 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
9847 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
9848 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
9849 * s/netbsd.h, s/sol2-6.h:
9850 Remove definition of GC_MARK_STACK, since the default now works.
9851 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
9852 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
9853 no longer the default.
9854 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
9856 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
9858 * lread.c (lisp_file_lexically_bound_p):
9859 Fix hang at ";-*-\n" (bug#11238).

9868 * nsterm.m (constrainFrameRect): Always constrain when there is only
9869 one screen (Bug#10962).
9871 2012-04-13 Ken Brown <kbrown@cornell.edu>

9879 2012-04-11 Daniel Colascione <dancol@dancol.org>
9881 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
9882 against is gone. It's better to use vfork now so that when Cygwin
9883 gains a new, working vfork, we use it automatically (bug#10398).
9885 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

9901 (handle_interrupt): Use it.
9903 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
9905 * w32.c (w32_delayed_load): Record the full path of the library
9906 being loaded (bug#10424).
9908 2012-04-09 Glenn Morris <rgm@gnu.org>
9910 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
9911 not just in the obarray, before snarfing them. (Bug#11036)
9913 * Makefile.in ($(leimdir)/leim-list.el):
9914 Pass EMACS rather than BUILT_EMACS.
9916 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
9918 * process.c (make_process):

9926 (emacs_gnutls_read): Use new log functions,
9927 `gnutls_handshakes_tried' process member, and

9929 attempts per process (connection).
9931 2012-04-09 Chong Yidong <cyd@gnu.org>
9933 * eval.c (Fuser_variable_p, user_variable_p_eh)

9938 * minibuf.c (Fread_variable): Callers changed.
9940 2012-04-09 Eli Zaretskii <eliz@gnu.org>
9942 * xdisp.c (set_cursor_from_row): If the display string appears in
9943 the buffer at position that is closer to point than the position
9944 after the display string, display the cursor on the first glyph of
9945 the display string. Fixes cursor display when a 'display' text
9946 property immediately follows invisible text. (Bug#11094)
9948 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
9950 composite.c: use 'double' consistently
9951 * composite.c (get_composition_id): Use 'double' consistently
9952 instead of converting 'float' to 'double' and vice versa; this is
9953 easier to understand and avoids a GCC warning.
9955 2012-04-09 Glenn Morris <rgm@gnu.org>
9957 * Makefile.in: Generate leim-list with bootstrap-emacs, in
9958 preparation for dumping it with emacs. (Bug#4789)

9980 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
9981 (mark_memory): Mark Lisp_Objects only if pointers might hide in
9982 objects, as mark_maybe_pointer will catch them otherwise.

9999 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
10000 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
10001 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
10002 [!WINDOWSNT]: New macros.
10003 (init_libxml2_functions, libxml2_loaded_p): New functions.
10004 (parse_region): Call fn_xmlCheckVersion instead of using the macro
10005 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
10006 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
10007 Calls xmlCleanupParser only if libxml2 was loaded (or statically
10009 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
10010 Call init_libxml2_functions before calling libxml2 functions.
10011 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
10013 * emacs.c: Don't include libxml/parser.h.
10014 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
10015 xmlCleanupParser directly.
10017 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
10019 2012-04-07 Eli Zaretskii <eliz@gnu.org>
10021 * indent.c (Fvertical_motion): If there is a display string at
10022 point, use it.vpos to compute how many lines to backtrack after
10023 move_it_to point. (Bug#11133)
10025 2012-04-06 Eli Zaretskii <eliz@gnu.org>
10027 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
10028 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
10029 about subtle differences between FETCH_CHAR* and STRING_CHAR*
10030 macros related to unification of CJK characters. For the details,
10031 see the discussion following the message here:
10032 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
10034 2012-04-04 Chong Yidong <cyd@gnu.org>
10036 * keyboard.c (Vdelayed_warnings_list): Doc fix.
10038 2012-04-01 Eli Zaretskii <eliz@gnu.org>
10040 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

10048 2012-03-31 Eli Zaretskii <eliz@gnu.org>
10050 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
10051 position we get to after a call to move_it_to fails the
10052 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
10053 only if we wind up in a string from display property. (Bug#11063)
10055 * window.c (Fdelete_other_windows_internal): Invalidate the row
10056 and column information about mouse highlight, so that redisplay
10057 restores it after reallocating the glyph matrices. (Bug#7464)
10059 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
10060 string comes from a `display' text property, use the buffer
10061 position of that property as if we actually saw that position in
10063 (move_it_by_lines): Remove the assertion that
10064 "it->current_x == 0 && it->hpos == 0" which can be legitimately
10065 violated when there's a before-string at the beginning of a line.
10068 2012-03-30 Eli Zaretskii <eliz@gnu.org>
10070 * xdisp.c (append_space_for_newline): If the default face was

10072 (extend_face_to_end_of_line): Use the remapped default face for
10073 extending the face to the end of the line.
10074 (display_line): Call extend_face_to_end_of_line when the default
10075 face was remapped. (Bug#11068)
10077 2012-03-29 Eli Zaretskii <eliz@gnu.org>
10079 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

10103 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
10105 2012-03-25 Kenichi Handa <handa@m17n.org>
10107 * dispextern.h (struct glyph): Change the bit length of
10108 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
10110 2012-03-24 Eli Zaretskii <eliz@gnu.org>
10112 * s/ms-w32.h (tzname): Include time.h before redirecting to

10121 !SYNC_INPUT. (Bug#11080)
10123 2012-03-23 Eli Zaretskii <eliz@gnu.org>
10125 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
10126 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
10127 when fetching a multibyte character consumes more bytes than
10128 CHAR_BYTES returns, due to unification of CJK characters in
10129 string_char. (Bug#11073)
10131 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
10133 * process.c (wait_reading_process_output): Handle pty disconnect

10168 that is not from display property, accept the row as a "cursor
10169 row" if one of the string's character has a non-nil `cursor'
10170 property. Fixes cursor positioning when there are newlines in
10171 overlay strings, e.g. in icomplete.el. (Bug#11035)
10173 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
10175 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
10177 2012-03-12 Chong Yidong <cyd@gnu.org>
10179 * eval.c (inhibit_lisp_code): Rename from
10180 inhibit_window_configuration_change_hook; move from window.c.
10182 * xfns.c (unwind_create_frame_1, Fx_create_frame):
10183 * window.c (run_window_configuration_change_hook)
10184 (syms_of_window): Callers changed.

10199 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
10201 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
10203 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
10204 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
10207 2012-03-03 Glenn Morris <rgm@gnu.org>
10209 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
10211 2012-03-02 Eli Zaretskii <eliz@gnu.org>
10213 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
10214 position past the first glyph_row that ends at ZV. (Bug#10902)
10215 (redisplay_window, next_element_from_string): Fix typos in
10217 (redisplay_window): Pass to move_it_vertically the margin in
10218 pixels, not in screen lines.
10220 2012-03-02 Glenn Morris <rgm@gnu.org>
10222 * buffer.c (buffer-list-update-hook): Doc fix.
10224 2012-02-29 Eli Zaretskii <eliz@gnu.org>
10226 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
10227 push_it before setting up the iterator for the first overlay
10228 string, even if we have an empty string loaded.
10229 (next_overlay_string): If there's an empty string on the iterator
10230 stack, pop the stack. (Bug#10903)
10232 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
10234 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
10235 Suggested by Stefan Monnier in
10236 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
10237 * alloc.c (widen_to_Lisp_Object): New static function.
10238 (mark_memory): Also mark Lisp_Objects by fetching pointer words
10239 and widening them to Lisp_Objects. This would work even if
10240 USE_LSB_TAG is defined and wide integers are used, which might
10241 happen in a future version of Emacs.
10243 2012-02-25 Chong Yidong <cyd@gnu.org>
10245 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
10248 * xselect.c (Fx_selection_exists_p): Doc fix.

10281 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
10282 when computing $valmask.
10284 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
10285 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
10286 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
10287 It's useless in that case, and it can cause problems on hosts
10288 that allocate halves of EMACS_INT values separately.
10289 Reported by Dan Horák. Diagnosed by Andreas Schwab in
10290 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
10291 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
10292 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
10293 it avoids undefined behavior on hosts where shifting right by more
10294 than the word width has undefined behavior.

10420 * character.c (char_width): Return EMACS_INT, not int.
10421 (char_width, c_string_width): Check for overflow when

10911 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
10912 verifies glyph row's hash code--we have just reallocated the

11078 is set, removing the need for VIRT_ADDRESS_VARIES.
11079 (PURE_P): Use a more-efficient implementation that needs just one

11096 behave as if the cursor position were at the window margin.
11098 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
11099 and the cursor position is out of bounds, behave as if the cursor
11100 position were at the window margin. (Bug#10075)
11102 2011-11-18 Chong Yidong <cyd@gnu.org>
11104 * window.c (Fwindow_combination_limit): Make first argument

11126 compute_line_metrics.
11127 (compute_line_metrics): Call row_hash, instead of computing the
11130 * dispnew.c (verify_row_hash): Call row_hash for computing the
11131 hash code of a row, instead of duplicating code from xdisp.c.
11133 * dispextern.h (row_hash): Add prototype.
11135 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
11137 * frame.c (delete_frame): Don't delete the terminal when the last

11186 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
11187 with user-defined heap size. Bump the default size of the temacs

11238 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
11240 Avoid some portability problems by eschewing 'extern inline' functions.
11241 The trivial performance wins aren't worth the portability hassles; see
11242 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
11244 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

11282 (Fset_window_new_total, Fset_window_new_normal)
11283 (Fwindow_resize_apply): Don't use term subwindow in doc-strings.
11284 (delete_all_subwindows): Rename to delete_all_child_windows.
11285 (Fdelete_other_windows_internal, Fset_window_configuration):
11286 Call delete_all_child_windows instead of delete_all_subwindows.
11287 * frame.c (delete_frame): Call delete_all_child_windows instead

11292 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
11293 This is also needed for porting to any host where GC_MARK_STACK is
11294 not GC_MAKE_GCPROS_NOOPS.
11295 (which_symbols): Use it.
11297 2011-11-07 Kenichi Handa <handa@m17n.org>

11310 * xmenu.c (cleanup_widget_value_tree): New function.
11311 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
11312 calling free_menubar_widget_value_tree directly (Bug#9830).

11316 Fix some portability problems with 'inline'.
11317 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
11318 (window_box_width, window_box_left, window_box_left_offset)
11319 (window_box_right, window_box_right_offset): Declare extern.
11320 Otherwise, these inline functions do not conform to C99 and
11321 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
11322 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
11323 * intervals.c (adjust_intervals_for_insertion)
11324 (adjust_intervals_for_deletion): Now extern, because otherwise the

11326 (static_offset_intervals): Remove.
11327 (offset_intervals): Rewrite using the old contents of
11328 static_offset_intervals. The old version didn't conform to C99
11329 because an extern inline function contained a reference to an
11330 identifier with static linkage.
11332 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
11334 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

11352 (Fwindow_vscroll): Doc fix.
11353 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
11354 argument, since it makes no sense to pass a live window and for
11355 consistency with window-child.

11396 official. Move initialization of image_cache_refcount and
11397 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

11565 (w32font_open_internal, compute_metrics):
11566 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
11567 instead of calling the "wide" APIs directly.

11642 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
11643 * editfns.c: Rewrite current-time-zone so that it invokes
11644 the equivalent of (format-time-string "%Z") to get the time zone name.
11645 This fixes a bug when the time zone name contains characters that
11646 need converting from the system time locale to Emacs internal format.
11647 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
11648 that patch fixed format-time-string to do the conversion, but
11649 I forgot to fix current-time-zone.
11650 (format_time_string): New function, containing most of
11651 what Fformat_time_string used to contain.
11652 (Fformat_time_string): Rewrite in terms of format_time_string.
11653 This doesn't change this function's behavior.

11655 This fixes the bug reported by Michael Schierl in
11656 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
11657 Jason Rumney's 2007-06-07 change worked around this bug, but
11659 * systime.h (tzname, timezone): Remove no-longer-used declarations.
11661 2011-10-19 Eli Zaretskii <eliz@gnu.org>
11663 * xdisp.c (start_display): If the character at POS is displayed
11664 via a display vector, reset IT->current.dpvec_index to zero.
11665 (try_window_reusing_current_matrix): If a line ends in a display
11666 vector or the next line starts in a display vector, continue
11667 redrawing the window even though the character position of
11668 start_row was reached.

11673 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
11674 with nobreak-char-display too.
11676 2011-10-18 Eli Zaretskii <eliz@gnu.org>
11678 Fix part 3 of bug#9771.
11679 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
11680 (bidi_resolve_neutral): Don't enter the expensive loop looking for
11681 non-neutral characters if the current character is a paragraph
11682 separator (a.k.a. Newline). This avoids running the same
11683 expensive loop twice, once when we consume the preceding newline
11684 and the other time when the line actually needs to be displayed.
11685 Avoid the loop when we see neutrals on the base embedding level
11686 following a character whose directionality is the same as the
11687 paragraph's. This avoids running the expensive loop when a line
11688 ends in a long sequence of neutrals, like control characters.
11689 Add assertion against STRONG_AL type. Slightly rearrange code
11690 that determines the type of a neutral given the first non-neutral
11692 (bidi_level_of_next_char): Set next_en_pos to zero when
11693 invalidating its info.
11695 2011-10-17 Eli Zaretskii <eliz@gnu.org>
11697 * xdisp.c (push_display_prop): Determine whether to record string
11698 or buffer position by IT->string, not by IT->method. Allow
11699 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
11700 (move_it_vertically_backward): Don't look for character position
11701 immediately after the newline when in a continuation line.
11704 2011-10-15 Martin Rudalics <rudalics@gmx.at>
11706 * window.c (coordinates_in_window): Rewrite and delabelize
11707 vertical border check. (Bug#5357) (Bug#9618)
11709 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
11711 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
11712 errors in XSetWindowBorder (bug#9310).
11714 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
11716 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
11717 avoid crash when xmalloc overrun checking is enabled.
11719 2011-10-13 Eli Zaretskii <eliz@gnu.org>
11721 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
11722 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
11723 cursor motion with <left> and <right> arrow keys.
11725 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
11726 some callers set that themselves.
11728 2011-10-12 Eli Zaretskii <eliz@gnu.org>
11730 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
11731 display string and the previous row comes from the same string and
11732 is empty. (Bug#9739) (Bug#9738)
11734 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
11736 * doc.c (get_doc_string): Encode file name (bug#9735).
11738 2011-10-12 Eli Zaretskii <eliz@gnu.org>
11740 * bidi.c (bidi_level_of_next_char):
11741 * xdisp.c (get_visually_first_element): Remove old incorrect
11742 comments regarding the Unicode Line Separator character.
11744 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
11746 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
11748 * alloc.c (Fgc_status): Do not access beyond zombies array
11749 boundary if nzombies > MAX_ZOMBIES.
11750 * alloc.c (dump_zombies): Add missing format specifier.
11752 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
11754 * xdisp.c (set_cursor_from_row): Simplify conditionals,
11755 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
11757 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
11758 Some packages use them to denote characters with modifiers.
11760 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
11762 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
11763 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
11764 matching a pp-number. Rename parameter var to var1.
11766 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
11768 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
11770 2011-10-08 Glenn Morris <rgm@gnu.org>
11772 * callint.c (Fcall_interactively): Give a more explicit error for the
11773 'c' case with a non-character input. (Bug#8479)
11775 2011-10-08 Eli Zaretskii <eliz@gnu.org>
11777 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
11779 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
11780 lines that are hscrolled on the left.
11782 * dispnew.c (buffer_posn_from_coords): Account for a possible
11783 presence of header-line. (Bug#4426)
11785 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
11787 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
11788 Don't advertise functionality which we discourage or doesn't work.
11790 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
11792 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
11793 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
11794 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
11795 this makes Emacs dump core during garbage collection on rare
11796 occasions. sizeof is obviously inferior to offsetof here, so
11797 stick with offsetof.
11798 (GC_POINTER_ALIGNMENT): New macro.
11799 (mark_memory): Omit 3rd (offset) arg; caller changed.
11800 Don't assume EMACS_INT alignment is the same as pointer alignment.
11802 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
11804 * keyboard.c (read_key_sequence_remapped): New var.
11805 (read_key_sequence): Compute remapping in the right buffer.
11806 (command_loop_1): Use read_key_sequence's remapping directly.
11808 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
11810 * dired.c (file_name_completion): Don't expand file name.
11811 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
11812 before checking file name handler.
11814 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
11815 they've been requested explicitly (bug#9591).
11817 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
11819 * keymap.c (Fsingle_key_description): Use make_specified_string
11820 instead of build_string to build string from push_key_description.
11823 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
11825 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
11826 This fixes a Y2038 bug on 64-bit hosts.
11827 * buffer.c (reset_buffer):
11828 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
11829 (Fclear_buffer_auto_save_failure):
11830 Use 0, not -1, to represent an unset failure time, since time_t
11831 might not be signed.
11833 Remove dependency on glibc malloc internals.
11834 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11835 Move back here from lisp.h, but with their new implementations.
11836 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11837 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
11838 * charset.c (charset_table_init): New static var.
11839 (syms_of_charset): Use it instead of xmalloc. This removes a
11840 dependency on glibc malloc internals. See Eli Zaretskii's comment in
11841 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
11842 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11843 Move back to alloc.c.
11844 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11845 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
11847 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
11849 * nsterm.m (windowDidResize): Call x_set_window_size only when
11850 ns_in_resize is true. Otherwise set pixelwidth/height and
11851 call change_frame_size (Bug#9628).
11853 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
11855 Port --enable-checking=all to Fedora 14 x86-64.
11856 * charset.c (syms_of_charset): Also account for glibc malloc's
11857 internal overhead when calculating the initial malloc maximum.
11859 Port --enable-checking=all to Fedora 14 x86.
11860 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11862 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
11863 (overrun_check_realloc, overrun_check_free):
11864 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
11865 That way, xmalloc returns a properly-aligned pointer even if
11866 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
11867 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
11868 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
11869 into account when calculating the initial malloc maximum.
11870 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11871 Move here from alloc.c, so that charset.c can use it too.
11872 Properly align; the old code wasn't right for common 32-bit hosts
11873 when configured with --enable-checking=all.
11874 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11875 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
11877 2011-09-29 Eli Zaretskii <eliz@gnu.org>
11879 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
11882 2011-09-28 Eli Zaretskii <eliz@gnu.org>
11884 * xdisp.c (compute_display_string_end): If there's no display
11885 string at CHARPOS, return -1.
11887 * bidi.c (bidi_fetch_char): When compute_display_string_end
11888 returns a negative value, treat the character as a normal
11889 character not covered by a display string. (Bug#9624)
11891 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
11893 * lread.c (Fread_from_string): Fix typo in docstring.
11895 2011-09-27 Eli Zaretskii <eliz@gnu.org>
11897 * xdisp.c (handle_invisible_prop): If invisible text ends on a
11898 newline, reseat the iterator instead of bidi-iterating there one
11899 character at a time. (Bug#9610)
11900 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
11901 TO_CHARPOS if the bidi iterator is at base embedding level.
11903 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
11905 * lread.c (readevalloop): Use correct code for NBSP.
11906 (read1): Likewise. (Bug#9608)
11908 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
11910 * dbusbind.c (Fdbus_register_signal): When service is not
11911 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
11913 2011-09-25 Glenn Morris <rgm@gnu.org>
11915 * buffer.c (truncate-lines): Doc fix.
11917 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
11919 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
11920 (Fset_window_next_buffers): Doc fix.
11922 2011-09-24 Glenn Morris <rgm@gnu.org>
11924 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
11926 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
11928 Fix minor problems found by static checking.
11929 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
11930 * indent.c (Fvertical_motion): Fix == vs = typo.
11932 2011-09-24 Eli Zaretskii <eliz@gnu.org>
11934 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
11935 Default value is now t. Doc fix.
11937 * indent.c (Fvertical_motion): Compute and apply the overshoot
11938 logic when moving up, not only when moving down. Fix the
11939 confusing name and values of the it_overshoot_expected variable;
11940 logic changes accordingly. (Bug#9254) (Bug#9549)
11942 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
11943 CHARPOS is covered by a display string which includes newlines.
11944 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
11945 is covered by a display string with embedded newlines.
11947 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
11949 * dbusbind.c (Fdbus_register_signal): Add match rule to
11950 Vdbus_registered_objects_table. (Bug#9581)
11951 (Fdbus_register_method, Vdbus_registered_objects_table):
11954 2011-09-24 Jim Meyering <meyering@redhat.com>
11956 do not ignore write error for any output size
11957 The previous change was incomplete.
11958 While it makes emacs --batch detect the vast majority of stdout
11959 write failures, errors were still ignored whenever the output size is
11960 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
11961 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
11962 && echo FAIL: ignored write error
11963 FAIL: ignored write error
11964 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
11965 && echo FAIL: ignored write error
11966 FAIL: ignored write error
11967 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
11969 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
11971 * emacs.c (Fkill_emacs): In noninteractive mode exit
11972 non-successfully if a write error occurred on stdout. (Bug#9574)
11974 2011-09-21 Eli Zaretskii <eliz@gnu.org>
11976 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
11979 * dispextern.h (struct it): Update the comment documenting what
11982 2011-09-20 Eli Zaretskii <eliz@gnu.org>
11984 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
11985 a display string, extend search for cursor position to end of row.
11986 (find_row_edges): If the row ends in a newline from a display
11987 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
11988 Handle the case of a display string with multiple newlines.
11989 (Fcurrent_bidi_paragraph_direction): Fix search for previous
11990 non-empty line. Fixes confusing cursor motion with arrow keys at
11991 the beginning of a line that starts with whitespace.
11993 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
11995 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
11998 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
12000 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
12001 boolean (Bug#9154).
12003 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12005 * xdisp.c (display_line): Record maximum and minimum buffer
12006 positions even if no glyphs were produced (e.g., by a zero-width
12007 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
12008 buffer positions that will be removed from the glyph row because
12010 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
12011 column is beyond frame width: don't subtract 1 "pixel" when
12012 computing width of the stretch.
12013 (reseat_at_next_visible_line_start): Undo the change made on
12014 2011-09-17 that saved paragraph information and restored it after
12015 the call to `reseat'. (Bug#9545)
12017 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12019 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
12020 and turn window cursor on if cleared (Bug#9415).
12022 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
12024 * search.c (boyer_moore): Take unibyte characters from pattern
12025 literally. (Bug#9458)
12027 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12029 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
12031 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
12033 Fix minor problem found by static checking.
12034 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
12035 initialized, to pacify gcc -Wuninitialized.
12037 * fileio.c: Report proper errno when syscall falls.
12038 (Finsert_file_contents): Save and restore errno,
12039 so that report_file_error outputs the correct diagnostic.
12040 (Fwrite_region) [CLASH_DETECTION]: Likewise.
12042 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12044 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
12046 2011-09-17 Eli Zaretskii <eliz@gnu.org>
12048 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
12049 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
12051 2011-09-17 Eli Zaretskii <eliz@gnu.org>
12053 * xdisp.c (reseat_at_next_visible_line_start): Keep information
12054 about the current paragraph and restore it after the call to reseat.
12056 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
12057 (bidi_find_paragraph_start): Search back for paragraph beginning
12058 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
12059 (bidi_move_to_visually_next): Only trigger paragraph-related
12060 computations when the last character is a newline or at EOB, not
12061 just any NEUTRAL_B. (Bug#9470)
12063 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
12064 truncated lines if point is covered by a display string. (Bug#9524)
12066 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
12068 * xselect.c: Relax test for outgoing X longs (Bug#9498).
12069 (cons_to_x_long): New function.
12070 (lisp_data_to_selection_data): Use it. Correct the test for
12071 short-versus-long data; it was negated. Break out of vector
12072 loop, for efficiency, when a long datum is discovered.
12074 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
12076 * eval.c (Fquote): Document its non-consing behavior (bug#9482).

12096 * term.c (encode_terminal_code):
12097 * composite.c (composition_update_it, get_composition_id):
12098 * xdisp.c (get_next_display_element)
12099 (fill_composite_glyph_string): Add comments about special meaning
12100 of TAB characters in a composition.
12102 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
12104 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
12105 This occurs when processing a multibyte format.
12106 Problem reported by Wolfgang Jenker.
12108 2011-09-15 Johan Bockgård <bojohan@gnu.org>
12110 * xdisp.c (try_cursor_movement): Only check for exact match if
12111 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
12113 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
12115 Remove unused external symbols.
12116 * dispextern.h (calc_pixel_width_or_height): Remove decl.
12117 * xdisp.c (calc_pixel_width_or_height): Now static.
12118 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.

12123 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
12125 * xselect.c: Use signed conversions more consistently (Bug#9498).
12126 (selection_data_to_lisp_data): Assume incoming selection data are
12127 signed integers, not unsigned. This is to be consistent with
12128 outgoing selection data, which was modified to use signed integers
12129 in as part of the fix to Bug#9196 in response to Jan D.'s comment
12130 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
12131 expects long, not unsigned long.
12133 2011-09-14 Eli Zaretskii <eliz@gnu.org>
12135 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
12136 computation of loop end. Reported by Johan Bockgård
12139 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
12141 * frame.c (Fother_visible_frames_p): Function deleted.
12143 2011-09-12 Eli Zaretskii <eliz@gnu.org>
12145 * indent.c (compute_motion): Process display vector front to back
12146 rather than the other way around. (Bug#2496)
12148 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
12150 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
12152 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
12154 * minibuf.c (Fread_from_minibuffer): Doc fix.
12156 2011-09-11 Eli Zaretskii <eliz@gnu.org>
12158 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
12159 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
12161 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
12163 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
12164 value for non-existent files.
12166 2011-09-11 Eli Zaretskii <eliz@gnu.org>
12168 * fileio.c (Finsert_file_contents): If the file cannot be opened,
12169 set its "size" to -1. This will set the modtime_size field of
12170 the corresponding buffer to -1, which is what
12171 verify-visited-file-modtime expects for files that do not exist.
12174 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
12176 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
12178 * lisp.h: ... from here. push_key_description is no longer
12179 defined in keyboard.c, so its declaration should not be in
12180 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
12181 logically belongs with push_key_description.
12183 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
12185 * buffer.h: Include <sys/types.h> instead of <time.h>.
12186 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
12187 Problem reported by Herbert J. Skuhra.
12189 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
12191 * xml.c (parse_region): Make the parsing work for
12192 non-comment-starting XML files again (bug#9144).
12194 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
12196 * image.c (gif_load): Fix calculation of bottom and right corner.
12199 2011-09-10 Eli Zaretskii <eliz@gnu.org>
12201 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
12202 redisplay in small windows.
12204 2011-09-09 Eli Zaretskii <eliz@gnu.org>
12206 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
12208 2011-09-08 Martin Rudalics <rudalics@gmx.at>
12210 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
12211 Operate on live windows only.
12213 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
12215 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
12217 2011-09-07 Eli Zaretskii <eliz@gnu.org>
12219 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
12220 only under bidi iteration.
12222 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
12224 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
12226 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12228 isnan: Fix porting problem to Solaris 10 with bundled gcc.
12229 Without this fix, the command to link temacs failed due to an
12230 undefined symbol __builtin_isnan. This is because
12231 /usr/include/iso/math_c99.h #defines isnan(x) to
12232 __builtin_isnan(x), but the bundled gcc, which identifies itself
12233 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
12235 * floatfns.c (isnan): #undef, and then #define to a clone of
12237 (Fisnan): Always define, since it's always available now.
12238 (syms_of_floatfns): Always define isnan at the Lisp level.
12240 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12242 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
12244 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12246 * fileio.c: Fix bugs with large file offsets (Bug#9428).
12247 The previous code assumed that file offsets (off_t values) fit in
12248 EMACS_INT variables, which is not true on typical 32-bit hosts.
12249 The code messed up by falsely reporting buffer overflow in cases
12250 such as (insert-file-contents "big" nil 1 2) into an empty buffer
12251 when "big" contains more than 2**29 bytes, even though this
12252 inserts just one byte and does not overflow the buffer.
12253 (Finsert_file_contents): Store file offsets as off_t
12254 values, not as EMACS_INT values. Check for overflow when
12255 converting between EMACS_INT and off_t. When checking for
12256 buffer overflow or for overlap, take the offsets into account.
12257 Don't use EMACS_INT for small values where int suffices.
12258 When checking for overlap, fix a typo: ZV was used where
12259 ZV_BYTE was intended.
12260 (Fwrite_region): Don't assume off_t fits into 'long'.
12261 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
12263 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
12265 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
12267 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
12269 sprintf-related integer and memory overflow issues (Bug#9412).
12271 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
12272 (esprintf, exprintf, evxprintf): New functions.
12273 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
12274 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
12275 (modify_event_symbol): Do not assume that the length of
12276 name_alist_or_stem is safe to alloca and fits in int.
12277 (Fexecute_extended_command): Likewise for function name and binding.
12278 (Frecursion_depth): Wrap around reliably on integer overflow.
12279 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
12280 since some callers pass EMACS_INT values.
12281 (Fsingle_key_description): Don't crash if symbol name contains more
12282 than MAX_ALLOCA bytes.
12283 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
12284 (get_minibuffer): Arg is now EMACS_INT, not int.
12285 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
12286 (esprintf, exprintf, evxprintf): New decls.
12287 * window.h (command_loop_level, minibuf_level): Reflect API changes.
12289 * dbusbind.c (signature_cat): New function.
12290 (xd_signature, Fdbus_register_signal):
12291 Do not overrun buffer; instead, report string overflow.
12293 * dispnew.c (add_window_display_history): Don't overrun buffer.
12294 Truncate instead; this is OK since it's just a log.
12296 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
12297 even if the time zone offset is outlandishly large.
12298 Don't mishandle offset == INT_MIN.
12300 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
12301 when creating daemon; the previous buffer-overflow check was incorrect.
12303 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
12304 which has the guts of the old verror function.
12306 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
12307 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
12309 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
12310 (font_unparse_xlfd): Don't blindly alloca long strings.
12311 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
12312 fits in int, when using sprintf. Use single snprintf to count
12313 length of string rather than counting it via multiple sprintfs;
12314 that's simpler and more reliable.
12315 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
12316 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
12317 sprintf, in case result does not fit in int.
12319 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
12320 (fontset_from_font): Print it.
12322 * frame.c (tty_frame_count): Now printmax_t, not int.
12323 (make_terminal_frame, set_term_frame_name): Print it.
12324 (x_report_frame_params): In X, window IDs are unsigned long,
12325 not signed long, so print them as unsigned.
12326 (validate_x_resource_name): Check for implausibly long names,
12327 and don't assume name length fits in 'int'.
12328 (x_get_resource_string): Don't blindly alloca invocation name;
12329 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
12332 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
12333 (xg_check_special_colors, xg_set_geometry):
12334 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
12336 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
12337 Use esprintf, not sprintf, in case result does not fit in int.
12339 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
12340 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
12341 it as a large positive number.
12342 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
12343 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
12345 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
12346 in case result does not fit in int.
12348 * print.c (float_to_string): Detect width overflow more reliably.
12349 (print_object): Make sprintf buffer a bit bigger, to avoid potential
12350 buffer overrun. Don't assume list length fits in 'int'. Treat
12351 print length of 0 as 0, not as infinity; to be consistent with other
12352 uses of print length in this function. Don't overflow print length
12353 index. Don't assume hash table size fits in 'long', or that
12354 vectorlike size fits in 'unsigned long'.
12356 * process.c (make_process): Use printmax_t, not int, to format
12357 process-name gensyms.
12359 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
12361 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
12362 to avoid potential buffer overrun.
12364 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
12365 if X resource line is longer than 512 bytes.
12367 * xfns.c (x_window): Make sprintf buffer a bit bigger
12368 to avoid potential buffer overrun.
12370 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
12372 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
12374 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
12376 Integer overflow fixes for scrolling, etc.
12377 Without these, Emacs silently mishandles large integers sometimes.
12378 For example, "C-u 4294967297 M-x recenter" was treated as if
12379 it were "C-u 1 M-x recenter" on a typical 64-bit host.
12381 * xdisp.c (try_window_id): Check Emacs fixnum range before
12382 converting to 'int'.
12384 * window.c (window_scroll_line_based, Frecenter):
12385 Check that an Emacs fixnum is in range before assigning it to 'int'.
12386 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
12387 values converted from Emacs fixnums.
12388 (Frecenter): Don't wrap around a line count if it is out of 'int'
12389 range; instead, treat it as an extreme value.
12390 (Fset_window_configuration, compare_window_configurations):
12391 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
12393 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
12394 that can exceed INT_MAX. Check that EMACS_INT value is in range
12395 before assigning it to the (possibly-narrower) index.
12396 (match_limit): Don't assume that a fixnum can fit in 'int'.
12398 * print.c (print_object): Use ptrdiff_t, not int, for index that can
12401 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
12402 (Fvertical_motion): Don't wrap around LINES values that don't fit
12403 in 'int'. Instead, treat them as extreme values. This is good
12404 enough for windows, which can't have more than INT_MAX lines anyway.
12406 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
12408 * Require libxml/parser.h to avoid compilation warning.
12410 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
12412 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
12413 since this reportedly can destroy thread storage.
12415 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
12417 * syntax.c (find_defun_start): Update all cache variables if
12418 exiting early (Bug#9401).
12420 2011-08-30 Eli Zaretskii <eliz@gnu.org>
12422 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
12424 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
12425 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
12426 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
12428 * term.c (tty_append_glyph): New function.
12429 (produce_stretch_glyph): Static function and its prototype deleted.
12431 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
12434 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
12436 * image.c (parse_image_spec): Check for nonnegative, not for positive,
12437 when checking :margin (Bug#9390).
12438 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
12439 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
12440 so that the name doesn't mislead. All uses changed.
12442 2011-08-28 Johan Bockgård <bojohan@gnu.org>
12444 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
12447 2011-08-27 Eli Zaretskii <eliz@gnu.org>
12449 * xdisp.c (move_it_to): Don't bail out early when reaching
12450 position beyond to_charpos, if we are scanning backwards.
12451 (move_it_vertically_backward): When DY == 0, make sure we get to
12452 the first character in the line after the newline.
12454 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
12456 * ccl.c: Improve and simplify overflow checking (Bug#9196).
12457 (ccl_driver): Do not generate an out-of-range pointer.
12458 (Fccl_execute_on_string): Remove unnecessary check for
12459 integer overflow, noted by Stefan Monnier in
12460 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
12461 Remove a FIXME that didn't need fixing.
12462 Simplify the newly-introduced buffer reallocation code.
12464 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
12466 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
12468 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
12470 Integer and memory overflow issues (Bug#9196).
12472 * doc.c (get_doc_string): Rework so that
12473 get_doc_string_buffer_size is the actual buffer size, rather than
12474 being 1 less than the actual buffer size; this makes xpalloc more
12477 * image.c (x_allocate_bitmap_record, cache_image):
12478 * xselect.c (Fx_register_dnd_atom):
12479 Simplify previous changes by using xpalloc.
12481 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
12482 since either will do and ptrdiff_t is convenient with xpalloc.
12484 * charset.c (charset_table_size)
12485 (struct charset_sort_data.priority): Now ptrdiff_t.
12486 (charset_compare): Don't overflow if priorities differ greatly.
12487 (Fsort_charsets): Don't assume list length fits in int.
12488 Check for size-calculation overflow when allocating sort data.
12489 (syms_of_charset): Allocate an initial charset table that is
12490 just under 64 KiB, to avoid problems with glibc malloc and mmap.
12492 * cmds.c (internal_self_insert): Check for size-calculation overflow.
12494 * composite.h (struct composition.glyph_len): Now int, not unsigned.
12495 The actual value is always <= INT_MAX, and leaving it unsigned made
12496 overflow checking harder.
12498 * dispextern.h (struct glyph_matrix.rows_allocated)
12499 (struct face_cache.size): Now ptrdiff_t, for convenience in use
12500 with xpalloc. The values are still always <= INT_MAX.
12502 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
12504 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
12505 (SAFE_NALLOCA): New macro.
12507 * region-cache.c (struct boundary.pos, find_cache_boundary)
12508 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
12509 (set_cache_region, invalidate_region_cache)
12510 (revalidate_region_cache, know_region_cache, region_cache_forward)
12511 (region_cache_backward, pp_cache):
12512 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
12513 so that ptrdiff_t * can be passed to xpalloc.
12514 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
12515 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
12516 (pp_cache): Don't assume cache_len fits in int.
12517 * region-cache.h: Adjust extern decls to match.
12519 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
12520 EMACS_INT, since either will do, for xpalloc.
12522 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
12523 (xnmalloc, xnrealloc, xpalloc): New functions.
12525 * bidi.c (bidi_shelve_header_size): New constant.
12526 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
12527 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
12529 * bidi.c (bidi_cache_shrink):
12530 * buffer.c (overlays_at, overlays_in, record_overlay_string)
12532 Don't update size of array until after memory allocation succeeds,
12533 because xmalloc/xrealloc may not return.
12534 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
12535 now that we have proper integer overflow checking.
12536 (record_overlay_string, overlay_strings): Catch overflows when
12537 calculating size of overlay_str_buf.
12539 * callproc.c (Fcall_process): Check for size overflow when
12540 calculating size of args2.
12541 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
12542 Normally we prefer signed values, but sticking with ptrdiff_t would
12543 require adding more-complicated checks.
12545 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
12546 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
12547 Redo buffer-overflow calculations to avoid integer overflow.
12548 Add a FIXME comment where memory seems to be over-allocated.
12550 * character.c (Fstring): Check for size-calculation overflow.
12552 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
12553 unnecessary integer overflow. Check for size overflow.
12554 (encode_coding_object): Don't update size until xmalloc succeeds.
12556 * composite.c (get_composition_id): Check for overflow in glyph
12557 length calculations.
12559 Integer and memory overflow fixes for display code.
12560 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
12561 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
12562 (scrolling_window): Check for overflow in size calculations.
12563 (line_draw_cost, realloc_glyph_pool, add_row_entry):
12564 Don't assume glyph table len fits in int.
12565 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
12566 (row_table_size): Now ptrdiff_t, not int.
12567 (scrolling_window): Avoid overflow in size calculations.
12568 Don't update size until allocation succeeds.
12569 * fns.c (concat): Check for overflow in size calculations.
12570 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
12571 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
12572 (NEXT_ALMOST_PRIME_LIMIT): New constant.
12574 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
12575 (get_doc_string): Check for size calculation overflow.
12576 Don't update size until allocation succeeds.
12577 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
12578 EMACS_INT, where ptrdiff_t will do.

12586 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
12588 * emacs.c (main): Do not reallocate argv, since there is a null at
12589 the end that can be overwritten, and this way there's no need to
12590 worry about size-calculation overflow.
12591 (sort_args): Check for size-calculation overflow.
12593 * eval.c (init_eval_once, grow_specpdl): Don't update size until

12599 Check for integer overflow.
12600 (x_set_alpha): Do not assume XINT fits in int.
12602 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
12603 This is for the members text_lines, text_cols, total_lines, total_cols,
12604 where the system imposes an 'int' limit.
12606 * fringe.c (Fdefine_fringe_bitmap):
12607 Don't update size until alloc works.

12613 Check for size-calculation overflow.
12614 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
12615 do, as we prefer signed integers.

12622 * gtkutil.h: Change prototypes to match the above.
12624 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these

12671 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
12672 for command line length. Do not attempt to address one before the
12673 beginning of an array, as that's not portable.
12675 * term.c (max_frame_lines): Remove; unused.

12702 (Finternal_make_lisp_face, cache_face):
12703 Check for size calculation overflow.
12704 (cache_face): Treat size calculation overflows as if they were
12705 memory exhaustion (the usual treatment), rather than aborting.
12707 * xfns.c (x_encode_text, x_set_name_internal)
12708 (Fx_change_window_property): Use ptrdiff_t, not int, to count
12709 sizes, since they can exceed INT_MAX in size. Check for size
12710 calculation overflow.

12713 (xg_select): Check for size calculation overflow.
12714 Don't update size until alloc done.
12716 * xrdb.c (get_environ_db): Don't assume path length fits in int,
12717 as sprintf is limited to int lengths.
12719 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
12720 (X_LONG_MIN): New macros.
12721 Use them to make the following changes clearer.
12722 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
12723 This change doesn't affect the value now, but it may help remind
12724 future maintainers not to raise the value too much later.
12725 (SELECTION_QUANTUM): Remove, replacing with ...
12726 (selection_quantum): ... new function, which avoids overflow.
12728 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
12729 assumption that selection length fits in 'int'.
12730 (x_reply_selection_request, x_handle_selection_request)
12731 (x_get_window_property, receive_incremental_selection)

12737 Redo calculations to avoid overflow.
12738 (x_reply_selection_request): When sending hint, ceiling it at

12746 Don't store size until memory allocation succeeds.
12747 (x_get_window_property): Plug memory leak on memory exhaustion.
12748 Don't double-block input; malloc is safe here. Don't assume 2**34
12749 - 4 fits in unsigned long. Add an xassert to check
12750 XGetWindowProperty overflow. Be more careful about overflow
12751 calculations, and distinguish size from memory overflow better.
12752 (receive_incremental_selection): When tracing, don't assume
12753 unsigned int is less than INT_MAX.
12754 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

12757 in the range -65535 through -1 fit in an X unsigned short.
12758 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
12759 result parameters unless successful. Rely on cons_to_unsigned
12760 to report problems with elements; the old code wasn't right anyway.
12761 (x_check_property_data): Check for int overflow; we cannot use
12762 a wider type due to X limits.
12763 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

12795 * lisp.h (hash_lookup, hash_put):
12796 * minibuf.c (Ftest_completion):
12797 Use ptrdiff_t for hash table indexes, not int (which is too
12798 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
12799 32-bit --with-wide-int hosts).
12801 * charset.c (Fdefine_charset_internal): Check for integer overflow.
12802 Add a FIXME comment about memory leaks.
12803 (syms_of_charset): Don't assume xmalloc returns.

12810 with outlandish widths.
12811 * character.h (sanitize_tab_width): Rename from sanitize_width,
12812 now that we have two such functions. All uses changed.

12830 * xterm.c: Don't go over XClientMessageEvent limit.
12831 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
12832 (x_send_scroll_bar_event): Likewise. Check that the size does not
12833 exceed limits imposed by XClientMessageEvent, as well as the usual
12834 ptrdiff_t and size_t limits.
12836 * keyboard.c: Overflow, signedness and related fixes.
12837 (make_lispy_movement): Use same integer type in forward decl
12838 that is used in the definition.
12839 (read_key_sequence, keyremap_step):
12840 Change bufsize argument back to int, undoing my 2011-03-30 change.
12841 We prefer signed types, and int is wide enough here.
12842 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
12843 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
12844 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
12845 length, not size_t. Use ptrdiff_t for index, not int.
12846 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
12847 possibility of integer overflow.
12849 Overflow, signedness and related fixes for images.

12875 Prefer int to unsigned where either will do.
12876 (tiff_handler): New function, combining the cores of the
12877 old tiff_error_handler and tiff_warning_handler.
12878 This function is rewritten to use vsnprintf and thereby avoid
12879 stack buffer overflows. It uses only the features of vsnprintf
12880 that are common to both POSIX and native Microsoft.
12881 (tiff_error_handler, tiff_warning_handler): Use it.
12882 (tiff_load, gif_load, imagemagick_load_image):
12883 Don't assume :index value fits in 'int'.
12884 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
12885 (imagemagick_load_image): Check that crop parameters fit into
12886 the integer types that MagickCropImage accepts. Don't assume
12887 Vimagemagick_render_type has a nonnegative value. Don't assume
12888 size_t fits in 'long'.
12889 (gs_load): Use printmax_t to print the widest integers possible.

12902 handle_single_display_spec, not just 1 or zero.
12903 (handle_single_display_spec): If the display spec is of the form
12904 `(space ...)', and specifies display in the text area, return 2
12906 (try_cursor_movement): Check for the need to scroll more
12907 accurately, and prefer exact match for point under bidi.
12908 Don't advance `row' beyond the last row of the window.

12926 buffers, return left-to-right.
12927 (set_cursor_from_row): Consider candidate row a win if its glyph
12928 represents a newline and point is on that newline. Fixes cursor
12929 positioning on the newline at EOL of R2L text within L2R
12930 paragraph, and vice versa.
12931 (try_cursor_movement): Check continued rows, in addition to
12932 continuation rows. Fixes unwarranted scroll when point enters a
12933 continued line of R2L text within an L2R paragraph, or vice versa.
12934 (cursor_row_p): Consider the case of point being equal to
12935 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
12936 from the end of a short line to the beginning of a continued line
12937 of R2L text within L2R paragraph.
12938 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

12959 2011-08-23 Eli Zaretskii <eliz@gnu.org>
12961 * xdisp.c (redisplay_window): When computing centering_position,
12962 account for the height of the header line. (Bug#8874)
12964 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
12965 instead of CHAR_TO_BYTE. Fixes a crash when a completion
12966 candidate is selected by the mouse, and that candidate has a
12967 composed character under the mouse.
12969 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
12970 coordinates reported by pos-visible-in-window-p for a composed
12971 character in column zero.
12973 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

12977 2011-08-22 Eli Zaretskii <eliz@gnu.org>
12979 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
12980 consider it a hit if to_charpos is anywhere in the range of the
12981 composed buffer positions.
12983 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
12985 * image.c (gif_load): Don't assume that each subimage has the same
12986 dimensions as the base image. Handle disposal method that is
12987 "undefined" by the gif spec (Bug#9335).
12989 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
12991 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

12994 2011-08-19 Eli Zaretskii <eliz@gnu.org>
12996 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
12997 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
12998 from an Org mode buffer to a Speedbar frame.
13000 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
13001 a composition, take its buffer position from IT->cmp_it.charpos.
13002 Fixes cursor positioning at the beginning of a line that begins
13003 with a composed character.
13005 2011-08-18 Eli Zaretskii <eliz@gnu.org>
13007 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
13008 character bidirectional type, use STRONG_L instead. Fixes crashes
13009 in a buffer produced by `describe-categories'.
13011 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
13012 members before the level stack, so they would be saved and
13013 restored when copying iterator state. Fixes incorrect reordering
13014 around TABs covered by display properties.
13016 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
13018 * process.c (Fnetwork_interface_list): Correctly determine buffer size.
13020 2011-08-17 Chong Yidong <cyd@stupidchicken.com>
13022 * eval.c (internal_condition_case, internal_condition_case_1)
13023 (internal_condition_case_2, internal_condition_case_n):
13024 Remove unnecessary aborts (Bug#9081).
13026 2011-08-17 Eli Zaretskii <eliz@gnu.org>
13028 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
13029 has no `load' handler, try opening the file locally. (Bug#9311)
13031 2011-08-16 Ken Brown <kbrown@cornell.edu>
13033 * gmalloc.c: Expand comment.
13035 2011-08-16 Eli Zaretskii <eliz@gnu.org>
13037 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
13038 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
13040 2011-08-16 Ken Brown <kbrown@cornell.edu>
13042 Fix memory allocation problems in Cygwin build (Bug#9273).
13044 * unexcw.c ( __malloc_initialized): Declare external variable.

13047 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
13049 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
13051 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
13052 in the static heap.
13053 [CYGWIN] (special_realloc): New function.
13054 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
13055 requests to realloc storage in the static heap.

13066 * deps.mk (bidi.o): Remove biditype.h and bidimirror.h.
13068 * dispextern.h: Fix a typo in the comment to bidi_type_t.
13070 * chartab.c: Improve commentary for the uniprop_table API.
13072 * bidi.c (bidi_paragraph_init): Support zero value of
13073 bidi_ignore_explicit_marks_for_paragraph_level.
13074 (bidi_initialize): Use uniprop_table instead of including
13075 biditype.h and bidimirror.h.
13077 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
13078 coordinates of the iterator when restoring from ppos_it.
13081 2011-08-14 Kenichi Handa <handa@m17n.org>
13083 * process.c (create_process): Call setup_process_coding_systems
13084 after the pid of the process is set to -1 (Bug#8162).
13086 2011-08-14 Eli Zaretskii <eliz@gnu.org>
13088 * xdisp.c (move_it_in_display_line_to): Don't invoke
13089 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
13090 ppos_it. Fixes vertical cursor motion when line beginning is
13091 covered by an image. (Bug#9296)
13093 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
13095 * nsterm.h (ns_run_ascript): Declare.
13096 (NSAPP_DATA2_RUNASSCRIPT): Define.
13098 * nsfns.m (as_script, as_result, as_status): New static variables.
13099 (ns_run_ascript): New function.
13100 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
13101 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
13102 the event loop. Get status from as_status (Bug#7276).
13104 * nsterm.m (sendEvent): If event is NSApplicationDefined and
13105 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
13106 the event loop (Bug#7276).
13108 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
13110 * gnutls.c (QCgnutls_bootprop_priority)
13111 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
13112 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
13113 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
13114 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
13115 (QCgnutls_bootprop_verify_hostname_error)
13116 (QCgnutls_bootprop_callbacks_verify): Rename from
13117 Qgnutls_bootprop_..., all uses changed.
13119 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
13122 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
13124 * xfaces.c (Qframe_set_background_mode): Now static.

13129 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
13131 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
13132 (Fnetwork_interface_list): Allocate in increments of bytes instead
13133 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
13134 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
13136 (struct ifflag_def): notrailers is smart on OSX.
13137 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
13138 Get hardware address with getifaddrs if available.
13140 2011-08-12 Eli Zaretskii <eliz@gnu.org>
13142 * xdisp.c (iterate_out_of_display_property): xassert that
13143 IT->position is set to within IT->object's boundaries. Break from
13144 the loop as soon as EOB is reached; avoids infloops in redisplay
13145 when IT->position is set up wrongly due to some bug.
13146 Set IT->current to match the bidi iterator unconditionally.
13147 (push_display_prop): Allow GET_FROM_STRING as IT->method on
13148 entry. Force push_it to save on the stack the current
13149 buffer/string position, to be restored by pop_it. Fix flags in
13150 the iterator structure wrt the object coming from a display
13151 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
13152 properties. (Bug#9284)
13154 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
13156 * fontset.c (fontset_get_font_group): Add proper type checks.
13159 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>

13162 and LC_VERSION_MIN_MACOSX.
13163 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
13164 (dump_it) [LC_FUNCTION_STARTS]: Use it.
13166 2011-08-08 Eli Zaretskii <eliz@gnu.org>
13168 * xdisp.c (forward_to_next_line_start): Allow to use the
13169 no-display-properties-and-no-overlays under bidi display.
13170 Set disp_pos in the bidi iterator to avoid searches for display
13171 properties and overlays.
13173 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
13175 * editfns.c (Fset_time_zone_rule): Document relationship with the

13179 the font entity extracted from the cache (Bug#8109).
13181 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
13183 * composite.c (autocmp_chars): Don't reset point. That is done by
13184 restore_point_unwind (Bug#5984).
13186 2011-08-07 Juri Linkov <juri@jurta.org>
13188 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
13189 to show the arg `TIME' instead of `TIMEVAL'.
13191 2011-08-06 Eli Zaretskii <eliz@gnu.org>
13193 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
13194 display property strides EOL and includes a newline, as in
13195 longlines-mode. (Bug#9254)
13196 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
13197 word-wrap under bidirectional display. (Bug#9224)
13199 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
13200 is non-zero, even if the data buffer is NULL. Fixes a crash in
13201 vertical-motion with longlines-mode. (Bug#9254)
13203 2011-08-05 Eli Zaretskii <eliz@gnu.org>
13205 * bidi.c <bidi_cache_total_alloc>: Now static.
13206 (bidi_initialize): Initialize bidi_cache_total_alloc.
13208 * xdisp.c (display_line): Release buffer allocated for shelved bidi
13211 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
13212 amount allocated this far in `bidi_cache_total_alloc'.
13213 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
13214 non-zero, only free the data buffer without restoring the cache
13215 contents. All callers changed.
13217 * dispextern.h (bidi_unshelve_cache): Update prototype.
13219 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
13220 (move_it_in_display_line, move_it_to)
13221 (move_it_vertically_backward, move_it_by_lines): Replace the call
13222 to xfree to an equivalent call to bidi_unshelve_cache.
13223 (move_it_in_display_line_to): Fix logic of returning
13224 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
13226 2011-08-05 Eli Zaretskii <eliz@gnu.org>
13228 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
13229 came from a string character with a `cursor' property. (Bug#9229)
13231 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
13233 * Makefile.in (LIB_PTHREAD): New variable.
13234 (LIBES): Add LIB_PTHREAD (Bug#9216).
13236 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
13237 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
13239 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
13241 * regex.c (re_iswctype): Remove some redundant boolean conversions.
13243 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
13245 * xterm.c (x_find_topmost_parent): New function.
13246 (x_set_frame_alpha): Find topmost parent window with
13247 x_find_topmost_parent and set the property there also (bug#9181).
13248 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
13250 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
13252 * callproc.c (Fcall_process): Avoid vfork clobbering
13253 the local vars buffer, coding_systems, current_dir.
13255 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
13257 * keymap.c (Fmake_composed_keymap): Move to subr.el.
13259 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
13261 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
13262 so that it is not optimized away.
13264 * xdisp.c (compute_display_string_pos): Remove unused local.
13266 2011-08-02 Eli Zaretskii <eliz@gnu.org>
13268 Fix slow cursor motion and scrolling in large buffers with
13269 selective display, like Org Mode buffers. (Bug#9218)
13271 * dispextern.h (struct bidi_it): New member disp_prop_p.
13273 * xdisp.c: Remove one-slot cache of display string positions.
13274 (compute_display_string_pos): Accept an additional argument
13275 DISP_PROP_P; callers changed. Scan at most 5K characters forward
13276 for a display string or property. If found, set DISP_PROP_P
13279 * bidi.c (bidi_fetch_char): Accept an additional argument
13280 DISP_PROP_P, and pass it to compute_display_string_pos.
13281 Only handle text covered by a display string if DISP_PROP_P is returned
13282 non-zero. All callers of bidi_fetch_char changed.
13284 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
13286 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
13288 2010-12-03 Don March <don@ohspite.net>
13290 * keymap.c (Fdefine_key): Fix non-prefix key error message when
13291 last character M-[char] is translated to ESC [char] (bug#7541).
13293 2011-08-02 Kenichi Handa <handa@m17n.org>
13295 * lisp.h (uniprop_table): Extern it.
13297 * chartab.c (uniprop_table): Make it non-static.
13299 2011-08-01 Eli Zaretskii <eliz@gnu.org>
13301 * xdisp.c (forward_to_next_line_start): Accept additional argument
13302 BIDI_IT_PREV, and store into it the state of the bidi iterator had
13304 (reseat_at_next_visible_line_start): Use the bidi iterator state
13305 returned by forward_to_next_line_start to restore the state of
13306 it->bidi_it after backing up to previous newline. (Bug#9212)
13308 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
13310 * regex.c (re_comp): Protoize.
13311 (re_exec): Fix return type.
13312 (regexec): Fix type of `ret'. (Bug#9203)
13314 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13316 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
13317 This is needed if max-image-size is a floating-point number.
13319 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
13321 * print.c (print_object): Print empty symbol as ##.
13323 * lread.c (read1): Read ## as empty symbol.
13325 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
13327 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
13328 setting frame foreground color (Bug#9175).
13329 (x_set_background_color): Likewise.
13331 * nsmenu.m (-setText): Size tooltip dimensions precisely to
13332 contents (Bug#9176).
13333 (EmacsTooltip -init): Remove bezels and add shadows to
13336 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
13337 or scroll bar (Bug#8470).
13339 * nsfont.m (nsfont_open): Remove assignment to voffset and
13340 unnecessary vars hshink, expand, hd, full_height, min_height.
13341 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
13343 * nsterm.h (nsfont_info): Remove voffset field.
13345 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
13347 Implement strike-through and overline on NextStep (Bug#8863).
13349 * nsfont.m (nsfont_open): Use underline position provided by font,
13350 instead of hard-coded value of 2.
13351 (nsfont_draw): Call ns_draw_text_decoration instead.
13353 * nsterm.h: Add declaration for ns_draw_text_decoration.
13355 * nsterm.m (ns_draw_text_decoration): New function for drawing
13356 underline, overline, and strike-through.
13357 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
13358 ns_draw_text_decoration. Change treatment of cursor drawing to
13359 accommodate underlining, etc.
13361 2011-07-28 Eli Zaretskii <eliz@gnu.org>
13363 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
13366 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13368 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
13369 Without this fix, if a signal arrives just after memory fills up,
13370 'malloc' might be invoked reentrantly.
13372 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
13373 In other words, assume that every image size is allowed, on non-X
13374 hosts. This assumption is probably wrong, but it lets Emacs compile.
13376 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
13378 * regex.c (re_iswctype): Convert return values to boolean.
13380 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
13382 * xdisp.c (compute_display_string_pos): Don't use cached display
13383 string position if the buffer had its restriction changed.
13386 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13388 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
13390 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13392 Integer signedness and overflow and related fixes. (Bug#9079)
13394 * bidi.c: Integer size and overflow fixes.
13395 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
13396 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
13397 (bidi_cache_find_level_change, bidi_cache_ensure_space)
13398 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
13399 (bidi_find_other_level_edge):
13400 Use ptrdiff_t instead of EMACS_INT where either will do.
13401 This works better on 32-bit hosts configured --with-wide-int.
13402 (bidi_cache_ensure_space): Check for size-calculation overflow.
13403 Use % rather than repeated addition, for better worst-case speed.
13404 Don't set bidi_cache_size until after xrealloc returns, because it
13406 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
13407 (bidi_cache_ensure_space): Also check that the bidi cache size
13408 does not exceed that of the largest Lisp string or buffer. See Eli
13409 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
13411 * alloc.c (__malloc_size_t): Remove.
13412 All uses replaced by size_t. See Andreas Schwab's note
13413 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
13415 * image.c: Improve checking for integer overflow.
13416 (check_image_size): Assume that f is nonnull, since
13417 it is always nonnull in practice. This is one less thing to
13418 worry about when checking for integer overflow later.
13419 (x_check_image_size): New function, which checks for integer
13420 overflow issues inside X.
13421 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
13422 This removes the need for a memory_full check.
13423 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
13424 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
13425 (xbm_read_bitmap_data): Change locals back to 'int', since
13426 their values must fit in 'int'.
13427 (xpm_load_image, png_load, tiff_load):
13428 Invoke x_create_x_image_and_pixmap earlier,
13429 to avoid much needless work if the image is too large.
13430 (tiff_load): Treat overly large images as if
13431 x_create_x_image_and_pixmap failed, not as malloc failures.
13432 (gs_load): Use x_check_image_size.
13434 * gtkutil.c: Omit integer casts.
13435 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
13436 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
13438 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
13440 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
13441 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
13442 would wrongly return t on a 64-bit host.
13444 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
13445 The plain *_OVERFLOW macros run afoul of GCC bug 49705
13446 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
13447 and therefore cause GCC to emit a bogus diagnostic in some cases.
13449 * image.c: Integer signedness and overflow and related fixes.
13450 This is not an exhaustive set of fixes, but it's time to
13451 record what I've got.
13452 (lookup_pixel_color, check_image_size): Remove redundant decls.
13453 (check_image_size): Don't assume that arbitrary EMACS_INT values
13454 fit in 'int', or that arbitrary 'double' values fit in 'int'.
13455 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
13456 (tiff_load, imagemagick_load_image):
13457 Check for overflow in size calculations.
13458 (x_create_x_image_and_pixmap): Remove unnecessary test for
13459 xmalloc returning NULL; that can't happen.
13460 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
13461 (xpm_color_bucket): Use better integer hashing function.
13462 (xpm_cache_color): Don't possibly over-allocate memory.
13463 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
13464 (gif_memory_source):
13465 Use ptrdiff_t, not int or size_t, to record sizes.
13466 (png_load): Don't assume values greater than 2**31 fit in 'int'.
13467 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
13468 either works, as we prefer signed integers.
13469 (tiff_read_from_memory, tiff_write_from_memory):
13470 Return tsize_t, not size_t, since that's what the TIFF API wants.
13471 (tiff_read_from_memory): Don't fail simply because the read would
13472 go past EOF; instead, return a short read.
13473 (tiff_load): Omit no-longer-needed casts.
13474 (Fimagemagick_types): Don't assume size fits into 'int'.
13476 Improve hashing quality when configured --with-wide-int.
13477 * fns.c (hash_string): New function, taken from sxhash_string.
13478 Do not discard information about ASCII character case; this
13479 discarding is no longer needed.
13480 (sxhash-string): Use it. Change sig to match it. Caller changed.
13481 * lisp.h: Declare it.
13482 * lread.c (hash_string): Remove, since we now use fns.c's version.
13483 The fns.c version returns a wider integer if --with-wide-int is
13484 specified, so this should help the quality of the hashing a bit.
13486 * emacs.c: Integer overflow minor fix.
13487 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
13488 Define only if GNU_LINUX.
13489 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
13491 * dispnew.c: Integer signedness and overflow fixes.
13492 Remove unnecessary forward decls, that were a maintenance hassle.
13493 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
13495 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
13496 (scrolling_window): Use ptrdiff_t, not int, for byte count.
13497 (prepare_desired_row, line_draw_cost):
13498 Use int, not unsigned, where either works.
13499 (save_current_matrix, restore_current_matrix):
13500 Use ptrdiff_t, not size_t, where either works.
13501 (init_display): Check for overflow more accurately, and without
13502 relying on undefined behavior.
13504 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
13505 Remove, replacing with the new symbols in lisp.h. All uses changed.
13506 * fileio.c (make_temp_name):
13507 * filelock.c (lock_file_1, lock_file):
13508 * xdisp.c (message_dolog):
13509 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
13510 Use pMd etc. instead.
13511 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
13512 replacing the pWIDE etc. symbols removed from editfns.c.
13514 * keyboard.h (num_input_events): Now uintmax_t.
13515 This is (very slightly) less likely to mess up due to wraparound.
13518 * buffer.c: Integer signedness fixes.
13519 (alloc_buffer_text, enlarge_buffer_text):
13520 Use ptrdiff_t rather than size_t when either will do, as we prefer
13523 * alloc.c: Integer signedness and overflow fixes.
13524 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
13525 (__malloc_size_t): Default to size_t, not to int.
13526 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
13527 (Fgarbage_collect, mark_object_loop_halt, mark_object):
13528 Prefer ptrdiff_t to size_t when either would do, as we prefer
13530 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
13531 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
13532 Now const. Initialize with values that are in range even if char
13534 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
13535 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
13536 These functions do the right thing with sizes > 2**32.
13537 (check_depth): Now ptrdiff_t, not int.
13538 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
13539 Adjust to new way of storing sizes. Check for size overflow bugs
13541 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
13542 slightly wrong anyway, as it missed one instance of
13543 XMALLOC_OVERRUN_CHECK_OVERHEAD.
13544 (refill_memory_reserve): Omit needless cast to size_t.
13545 (mark_object_loop_halt): Mark as externally visible.
13547 * xselect.c: Integer signedness and overflow fixes.
13548 (Fx_register_dnd_atom, x_handle_dnd_message):
13549 Use ptrdiff_t, not size_t, since we prefer signed.
13550 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
13551 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
13552 x_dnd_atoms_size and x_dnd_atoms_length.
13554 * doprnt.c: Prefer signed to unsigned when either works.
13556 * doprnt.c (doprnt):
13558 * xdisp.c (vmessage):
13559 Use ptrdiff_t, not size_t, when using or implementing doprnt,
13560 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
13561 prefer signed arithmetic to avoid comparison confusion.
13562 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
13563 but is a bit tricky.
13565 Assume freestanding C89 headers, string.h, stdlib.h.
13566 * data.c, doprnt.c, floatfns.c, print.c:
13567 Include float.h unconditionally.
13568 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
13569 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
13570 * regex.c: Likewise for stddef.h, string.h.
13571 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
13572 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
13573 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
13574 (STDC_HEADERS): Remove obsolete defines.
13575 * sysdep.c: Include limits.h unconditionally.
13577 Assume support for memcmp, memcpy, memmove, memset.
13578 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
13579 * regex.c (memcmp, memcpy):
13580 Remove; we assume C89 now.
13582 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
13583 (__malloc_safe_bcopy): Remove; no longer needed.
13585 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
13586 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
13587 well either way, and we prefer signed to unsigned.
13589 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
13591 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
13592 closes the connection while we're reading (bug#9182).
13594 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
13596 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
13597 are specified (Bug#9168).
13599 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
13601 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
13602 Found by GCC static checking and --with-wide-int on a 32-bit host.
13604 2011-07-25 Eli Zaretskii <eliz@gnu.org>
13606 * xdisp.c (compute_display_string_pos): Fix logic of caching
13607 previous display string position. Initialize cached_prev_pos to
13608 -1. Fixes slow-down at the beginning of a buffer.
13610 2011-07-24 Eli Zaretskii <eliz@gnu.org>
13612 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
13613 for attrs[LFACE_FONTSET_INDEX].
13615 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
13617 * xml.c (parse_region): Remove unused local
13618 that was recently introduced.
13620 2011-07-23 Eli Zaretskii <eliz@gnu.org>
13622 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
13623 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
13625 * xdisp.c (move_it_in_display_line_to): Record the best matching
13626 position for TO_CHARPOS while scanning the line, and restore it on
13627 exit if none of the characters scanned was an exact match.
13628 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
13629 when exact match is impossible due to invisible text, and the
13630 lines are truncated.
13632 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
13634 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
13637 2011-07-22 Eli Zaretskii <eliz@gnu.org>
13639 Fix a significant slow-down of cursor motion with C-n, C-p,
13640 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
13641 auto-repeat under bidi redisplay in fontified buffers.
13642 * xdisp.c (compute_stop_pos_backwards): New function.
13643 (next_element_from_buffer): Call compute_stop_pos_backwards to
13644 find a suitable prev_stop when we find ourselves before
13646 (reseat): Don't look for prev_stop, as that could mean a very long
13648 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
13649 <cached_disp_overlay_modiff>: Cache for last found display string
13651 (compute_display_string_pos): Return the cached position if asked
13652 about the same buffer in the same area of character positions, and
13653 the buffer wasn't changed since the time the display string
13654 position was cached.
13656 2011-07-22 Eli Zaretskii <eliz@gnu.org>
13658 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
13659 is an integer, which is important for empty lines. (Bug#9149)
13661 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
13663 * frame.c (Fmodify_frame_parameters): In tty case, update the
13664 default face if necessary (Bug#4238).
13666 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
13668 * editfns.c (Fstring_to_char): No need to explain what a character
13669 is in the docstring (Bug#6576).
13671 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
13673 * xml.c (parse_region): Make sure we always return a tree.
13675 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
13677 * xml.c (parse_region): If a document contains only comments,
13680 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
13682 * xml.c (make_dom): Return comments, too.
13684 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
13687 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
13688 and the surrounding thread.
13689 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
13690 rather than fgets, and retry after EINTR. Otherwise, 'emacs
13691 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
13693 * s/openbsd.h (BROKEN_SIGIO): Define.
13694 * unexelf.c (unexec) [__OpenBSD__]:
13695 Don't update the .mdebug section of the Alpha COFF symbol table.
13697 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
13699 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
13702 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
13704 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
13705 This fixes some race conditions on the permissions of any newly
13708 * alloc.c (valid_pointer_p): Use pipe, not open.
13709 This fixes some permissions issues when debugging.
13711 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
13712 If fchown fails to set both uid and gid, try to set just gid,
13713 as that is sometimes allowed. Adjust the file's mode to eliminate
13714 setuid or setgid bits that are inappropriate if fchown fails.
13716 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
13718 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
13719 to compare Lisp_Objects.
13720 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
13721 global_gnutls_log_level, don't mistake it for a Lisp_Object.
13722 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
13724 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
13726 * lread.c (read_integer): Unread even EOF character.
13727 (read1): Likewise. Properly record start position of symbol.
13729 * lread.c (read1): Read `#:' as empty uninterned symbol if no
13730 symbol character follows.
13732 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
13734 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
13735 This works around a problem with the previous change to Fcopy_file.
13736 Recent glibc declares fchown with __attribute__((warn_unused_result)),
13737 and without this change, GCC might complain about discarding
13738 fchown's return value.
13740 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
13742 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
13744 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
13746 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
13748 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
13750 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
13751 it's used from the C level.
13753 * process.c: Use the same condition for POLL_FOR_INPUT in both
13754 keyboard.c and process.c (bug#1858).
13756 2011-07-09 Lawrence Mitchell <wence@gmx.li>
13758 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
13759 (Fgnutls_boot): Use it.
13761 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
13763 * doc.c (Fsubstitute_command_keys): Revert last change.
13765 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
13767 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
13768 quotes the next character, and doesn't affect other longer
13769 sequences (bug#8935).
13771 * lread.c (syms_of_lread): Clarify that is isn't only
13772 `eval-buffer' and `eval-defun' that's affected by
13773 `lexical-binding' (bug#8460).
13775 2011-07-15 Eli Zaretskii <eliz@gnu.org>
13777 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
13778 bidi redisplay when a line includes both an image and is truncated.
13780 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
13782 Fix minor problems found by static checking.
13783 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
13784 (elsz): Now a signed constant, not a size_t var. We prefer signed
13785 types to unsigned, to avoid integer comparison confusion. Without
13786 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
13787 "cannot optimize loop, the loop counter may overflow", a symptom
13789 * indent.c (Fvertical_motion): Mark locals as initialized.
13790 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
13792 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
13794 * search.c (Fre_search_backward): Mention `case-fold-search' in
13795 all the re_search_* functions (bug#8138).
13797 * keyboard.c (Fopen_dribble_file): Document when the file is
13800 2011-07-14 Eli Zaretskii <eliz@gnu.org>
13802 * bidi.c (bidi_dump_cached_states): Fix format of displaying
13805 Support bidi reordering of display and overlay strings.

13807 (compute_display_string_end): Accept additional argument STRING.
13808 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
13809 (reseat_to_string): Initialize bidi_it->string.s and
13810 bidi_it->string.schars.
13811 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
13812 NULL (avoids a crash in bidi_paragraph_init).
13813 Initialize itb.string.lstring.
13814 (init_iterator): Call bidi_init_it only of a valid
13815 buffer position was specified. Initialize paragraph_embedding to
13817 (reseat_to_string): Initialize the bidi iterator.
13818 (display_string): If we need to ignore text properties of
13819 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
13820 original value of -1 will not work with bidi.)
13821 (compute_display_string_pos): First arg is now struct
13822 `text_pos *'; all callers changed. Support display properties on
13824 (compute_display_string_end): Support display properties on Lisp
13826 (init_iterator, reseat_1, reseat_to_string): Initialize the
13827 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
13828 when iterating on a string not from display properties).
13829 (compute_display_string_pos, compute_display_string_end):
13830 Fix calculation of the object to scan. Fixes an error when using
13832 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
13833 base_level_stop; instead, set base_level_stop to BEGV.
13834 Fixes crashes in vertical-motion.
13835 (next_element_from_buffer): Improve commentary for when
13836 the iterator is before prev_stop.
13837 (init_iterator): Initialize bidi_p from the default value of
13838 bidi-display-reordering, not from buffer-local value. Use the
13839 buffer-local value only if initializing for buffer iteration.
13840 (handle_invisible_prop): Support invisible properties on strings
13841 that are being bidi-reordered.
13842 (set_iterator_to_next): Support bidi reordering of C strings and
13844 (next_element_from_string): Support bidi reordering of Lisp
13846 (handle_stop_backwards): Support Lisp strings as well.
13847 (display_string): Support display of R2L glyph rows.
13848 Use IT_STRING_CHARPOS when displaying from a Lisp string.
13849 (init_iterator): Don't initialize it->bidi_p for strings
13851 (reseat_to_string): Initialize it->bidi_p for strings here.
13852 (next_element_from_string, next_element_from_c_string)
13853 (next_element_from_buffer): Add xassert's for correspondence
13854 between IT's object being iterated and it->bidi_it.string
13856 (face_before_or_after_it_pos): Support bidi iteration.
13857 (next_element_from_c_string): Handle the case of the first string
13858 character that is not the first one in the visual order.
13859 (get_visually_first_element): New function, refactored from common
13860 parts of next_element_from_buffer, next_element_from_string, and
13861 next_element_from_c_string.
13862 (tool_bar_lines_needed, redisplay_tool_bar)
13863 (display_menu_bar): Force left-to-right direction. Add a FIXME
13864 comment for making that be controlled by a user option.
13865 (push_it, pop_it): Save and restore the state of the
13866 bidi iterator. Save and restore the bidi_p flag.
13867 (pop_it): Iterate out of display property for string iteration as
13869 (iterate_out_of_display_property): Support iteration over strings.
13870 (handle_single_display_spec): Set up it->bidi_it for iteration
13871 over a display string, and call bidi_init_it.
13872 (handle_single_display_spec, next_overlay_string)
13873 (get_overlay_strings_1, push_display_prop): Set up the bidi
13874 iterator for displaying display or overlay strings.
13875 (forward_to_next_line_start): Don't use the shortcut if
13877 (back_to_previous_visible_line_start): If handle_display_prop
13878 pushed the iterator stack, restore the internal state of the bidi
13879 iterator by calling bidi_pop_it same number of times.
13880 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
13881 and we are bidi-iterating, don't decrement the iterator position;
13882 instead, set the first_elt flag in the bidi iterator, to produce
13884 (reseat_1): Remove redundant setting of string_from_display_prop_p.
13885 (push_display_prop): xassert that we are iterating a buffer.
13886 (push_it, pop_it): Save and restore paragraph_embedding member.
13887 (handle_single_display_spec, next_overlay_string)
13888 (get_overlay_strings_1, reseat_1, reseat_to_string)
13889 (push_display_prop): Set up the `unibyte' member of bidi_it.string
13890 correctly. Don't assume unibyte strings are not bidi-reordered.
13891 (compute_display_string_pos)
13892 (compute_display_string_end): Fix handling the case of C string.
13893 (push_it, pop_it): Save and restore from_disp_prop_p.
13894 (handle_single_display_spec, push_display_prop): Set the
13895 from_disp_prop_p flag.
13896 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
13897 (pop_it): Call iterate_out_of_display_property only if we are
13898 popping after iteration over a string that came from a display
13899 property. Fix a typo in popping stretch info. Add an assertion
13900 for verifying that the iterator position is in sync with the bidi
13902 (handle_single_display_spec, get_overlay_strings_1)
13903 (push_display_prop): Fix initialization of paragraph direction for
13904 string when that of the parent object is not yet determined.
13905 (reseat_1): Call bidi_init_it to resync the bidi
13906 iterator with IT's position. (Bug#7616)
13907 (find_row_edges): If ROW->start.pos gives position
13908 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
13909 (handle_stop, back_to_previous_visible_line_start, reseat_1):
13910 Reset the from_disp_prop_p flag.
13911 (SAVE_IT, RESTORE_IT): New macros.

14353 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
14355 Random fixes. E.g., (random) never returned negative values.
14356 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
14357 subseconds part to the entropy, as that's a bit more random.
14358 Prefer signed to unsigned, since the signedness doesn't matter and
14359 in general we prefer signed. When given a limit, use a
14360 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
14361 latter isn't right if USE_2_TAGS_FOR_INTS.
14362 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
14363 not 0..VALMASK. Don't discard "excess" bits that random () returns.
14365 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
14367 * textprop.c (text_property_stickiness):
14368 Obey Vtext_property_default_nonsticky.

14375 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
14376 This is more efficient than Ffile_directory_p and avoids a minor race.
14378 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
14380 * buffer.c (Foverlay_put): Say what the return value is
14383 * fileio.c (barf_or_query_if_file_exists): Check first if the file
14384 is a directory before asking whether to use the file name
14386 (barf_or_query_if_file_exists): Make the "File is a directory"
14387 error be more correct.
14389 * fns.c (Frequire): Remove the mention of the .gz files, since
14390 that's installation-specific, but keep the mention of
14391 `get-load-suffixes'.
14393 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
14395 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

14400 * gnutls.c (Fgnutls_boot): Don't mention :verify-error.
14401 (syms_of_gnutls): Remove duplicate DEFSYM for
14402 Qgnutls_bootprop_verify_hostname_error, an error for
14403 Qgnutls_bootprop_verify_error (which is no longer used).
14405 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
14406 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
14407 Also (re)move comments that are misplaced or no longer relevant.
14409 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
14411 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

14436 * lread.c (syms_of_lread): Mention single symbols defined by
14437 `defvar' or `defconst' (bug#7154).
14439 * fns.c (Frequire): Mention .el.gz files (bug#7314).
14440 (Frequire): Mention get-load-suffixes.
14442 2011-07-02 Martin Rudalics <rudalics@gmx.at>

14508 * eval.c (struct backtrace): Simplify and port the data structure.
14509 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
14510 signed bit field, as this assumption is not portable and it makes
14511 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
14512 "char debug_on_exit : 1" as this is not portable either; instead,
14513 use the portable "unsigned int debug_on_exit : 1". Remove unused
14514 member evalargs. Remove obsolete comments about cc bombing out.
14516 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>
14518 * xsettings.c: Include glib-object.h, gio/gio.h if HAVE_GSETTINGS.

14584 (emacs_fixed_new): Set priv->f to argument.
14585 (emacs_fixed_get_preferred_width)
14586 (emacs_fixed_get_preferred_height): Use min_width/height from
14587 frames size_hint to set minimum and natural (Bug#8919).
14588 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
14589 and use min_width/height from frames size_hint to set
14590 min_width/height (Bug#8919).

14682 * print.c (printchar, strout): Check for string overflow.
14683 (PRINTPREPARE, printchar, strout):
14684 Don't set size unless allocation succeeds.
14686 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
14687 for sizes. Check for string overflow more accurately.

14701 (read_integer): Radix is now EMACS_INT, not int,
14702 to improve quality of diagnostics for out-of-range radices.
14703 Calculate buffer size correctly for out-of-range radices.
14704 (read1): Check for integer overflow in radices, and in
14705 read-circle numbers.
14706 (read_escape): Avoid int overflow.
14707 (Fload, openp, read_buffer_size, read1)
14708 (substitute_object_recurse, read_vector, read_list, map_obarray):
14709 Use ptrdiff_t, not int, for sizes.

14731 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
14732 The following patches are for when GLYPH_DEBUG && !XASSERT.
14733 * dispextern.h (trace_redisplay_p, dump_glyph_string):
14734 * dispnew.c (flush_stdout):
14735 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
14736 Mark as externally visible.
14737 * dispnew.c (check_window_matrix_pointers): Now static.
14738 * dispnew.c (window_to_frame_vpos):
14739 * xfns.c (unwind_create_frame):

14746 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
14748 (debug_method_add): Use va_list and vsprintf rather than relying
14749 on undefined behavior with wrong number of arguments.
14750 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
14751 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
14752 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
14753 since we're not interested in debugging glyphs with old libraries.
14754 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
14755 GCC 4.6.0's static checking.
14757 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

14786 * xfaces.c (face_at_buffer_position):
14787 * buffer.c (OVERLAY_COUNT_MAX): New macro.
14788 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
14789 (Fnext_overlay_change, Fprevious_overlay_change)
14790 (mouse_face_overlay_overlaps, Foverlays_in):
14791 Use ptrdiff_t, not int, for sizes.
14792 (overlays_at, overlays_in): Check for size-calculation overflow.
14794 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
14796 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
14797 (x_session_initialize): Do not assume string length fits in int.
14799 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
14800 This is unlikely, but can occur if DPI is outlandish.
14802 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
14803 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
14805 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
14806 * xrdb.c (magic_file_p, search_magic_path):
14807 Omit last arg SUFFIX; it was always 0. All callers changed.
14808 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
14810 * xfont.c (xfont_match): Avoid need for strlen.
14812 * xfns.c: Don't assume strlen fits in int.
14813 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
14815 * xdisp.c (message_log_check_duplicate): Return intmax_t,
14816 not unsigned long, as we prefer signed integers. All callers changed.
14817 Detect integer overflow in repeat count.
14818 (message_dolog): Don't assume print length fits in 39 bytes.
14819 (display_mode_element): Don't assume strlen fits in int.
14821 * termcap.c: Don't assume sizes fit in int and never overflow.
14822 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
14823 (gobble_line): Check for size-calculation overflow.
14825 * minibuf.c (Fread_buffer):
14826 * lread.c (intern, intern_c_string):
14827 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
14828 Don't assume string length fits in int.
14830 * keyboard.c (parse_tool_bar_item):
14831 * gtkutil.c (style_changed_cb): Avoid need for strlen.
14833 * font.c: Don't assume string length fits in int.
14834 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
14835 Use ptrdiff_t, not int.
14836 (font_intern_prop): Don't assume string length fits in int.
14837 Don't assume integer property fits in fixnum.
14838 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
14840 * filelock.c: Fix some buffer overrun and integer overflow issues.
14841 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
14842 Reformulate so as not to need the command string.
14843 Invoke gzip -cd rather than gunzip, as it's more portable.
14844 (lock_info_type, lock_file_1, lock_file):
14845 Don't assume pid_t and time_t fit in unsigned long.
14846 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
14847 (current_lock_owner): Prefer signed type for sizes.
14848 Use memcpy, not strncpy, where memcpy is what is really wanted.
14849 Don't assume (via atoi) that time_t and pid_t fit in int.
14850 Check for time_t and/or pid_t out of range, e.g., via a network share.
14851 Don't alloca where an auto var works fine.
14853 * fileio.c: Fix some integer overflow issues.
14854 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
14855 Don't assume string length fits in int.
14856 (directory_file_name): Don't assume string length fits in long.
14857 (make_temp_name): Don't assume pid fits in int, or that its print
14858 length is less than 20.
14860 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
14862 * coding.c (make_subsidiaries): Don't assume string length fits in int.
14864 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
14866 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
14867 We prefer signed integers, even for size calculations.
14869 * emacs.c: Don't assume string length fits in 'int'.
14870 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
14871 (main): Don't invoke strlen when not needed.
14873 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
14874 (XD_DEBUG_MESSAGE): Don't waste a byte.
14876 * callproc.c (getenv_internal_1, getenv_internal)
14877 (Fgetenv_internal):
14878 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
14880 * lread.c (invalid_syntax): Omit length argument.
14881 All uses changed. This doesn't fix a bug, but it simplifies the
14882 code away from its former Hollerith-constant appearance, and it's
14883 one less 'int' to worry about when looking at integer-overflow issues.
14884 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
14886 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
14887 This didn't break anything, but it didn't help either.
14888 It's confusing to put a bogus integer in a place where the actual
14889 value does not matter.
14890 (LIST_END_P): Remove unused macro and its bogus comment.
14891 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
14893 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
14894 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
14896 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
14897 We prefer signed types, and the value cannot exceed the EMACS_INT
14898 range anyway (because otherwise the length would not be representable).
14899 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
14900 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
14901 This avoids a GCC warning when WIDE_EMACS_INT.
14903 * indent.c (sane_tab_width): New function.
14904 (current_column, scan_for_column, Findent_to, position_indentation)
14905 (compute_motion): Use it. This is just for clarity.
14906 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
14908 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
14910 * lisp.h (lint_assume): New macro.
14911 * composite.c (composition_gstring_put_cache):
14912 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
14914 * editfns.c, insdel.c:
14915 Omit unnecessary forward decls, to simplify future changes.
14917 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
14919 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
14921 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
14922 Use much-faster test for byte-length change.
14923 Don't assume string byte-length fits in 'int'.
14924 Check that character arg fits in 'int'.
14925 (mapcar1): Declare byte as byte, for clarity.
14927 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
14929 * fns.c (concat): Catch string overflow earlier.
14930 Do not rely on integer wraparound.
14932 * dispextern.h (struct it.overlay_strings_charpos)
14933 (struct it.selective): Now EMACS_INT, not int.
14934 * xdisp.c (forward_to_next_line_start)
14935 (back_to_previous_visible_line_start)
14936 (reseat_at_next_visible_line_start, next_element_from_buffer):
14937 Don't arbitrarily truncate the value of 'selective' to int.
14939 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
14941 * composite.c: Don't truncate sizes to 'int'.
14942 (composition_gstring_p, composition_reseat_it)
14943 (composition_adjust_point): Use EMACS_INT, not int.
14944 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
14945 not EMACS_UINT, for indexes.
14947 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
14949 * buffer.c: Include <verify.h>.
14950 (struct sortvec.priority, struct sortstr.priority):
14951 Now EMACS_INT, not int.
14952 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
14953 (struct sortstr.size, record_overlay_string)
14954 (struct sortstrlist.size, struct sortlist.used):
14955 Don't truncate size to int.
14956 (record_overlay_string): Check for size-calculation overflow.
14957 (init_buffer_once): Check at compile-time, not run-time.
14959 2011-06-22 Jim Meyering <meyering@redhat.com>
14961 Don't leak an XBM-image-sized buffer
14962 * image.c (xbm_load): Free the image buffer after using it.
14964 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
14967 * composite.c (find_automatic_composition): Omit needless 'return 0;'
14968 that Sun C diagnosed.
14969 * fns.c (secure_hash): Fix pointer signedness issue.
14970 * intervals.c (static_offset_intervals): New function.
14971 (offset_intervals): Use it.
14973 2011-06-21 Leo Liu <sdl.web@gmail.com>
14976 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
14979 * fns.c (secure_hash): Rename from crypto_hash_function and change
14980 the first arg to accept symbols.
14981 (Fsecure_hash): New primitive.
14982 (syms_of_fns): New symbols.
14984 2011-06-20 Deniz Dogan <deniz@dogan.se>
14986 * process.c (Fset_process_buffer): Clarify return value in
14989 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
14991 * dispnew.c (add_window_display_history): Use BVAR.
14993 * xdisp.c (debug_method_add): Use BVAR.
14994 (check_window_end, dump_glyph_matrix, dump_glyph)
14995 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
14997 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
15000 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
15001 check till after the cache is created in init_frame_faces.
15003 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
15005 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
15007 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
15009 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
15010 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
15011 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
15013 Improve buffer-overflow checking (Bug#8873).
15014 * fileio.c (Finsert_file_contents):
15015 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
15016 Remove the old (too-loose) buffer overflow checks.
15017 They weren't needed, since make_gap checks for buffer overflow.
15018 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
15019 The old code merely checked for Emacs fixnum overflow, and relied
15020 on undefined (wraparound) behavior. The new code avoids undefined
15021 behavior, and also checks for ptrdiff_t and/or size_t overflow.
15023 * editfns.c (Finsert_char): Don't dump core with very negative counts.
15024 Tune. Don't use wider integers than needed. Don't use alloca.
15025 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
15027 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
15029 * insdel.c, lisp.h (buffer_overflow): New function.
15030 (insert_from_buffer_1, replace_range, replace_range_2):
15031 * insdel.c (make_gap_larger):
15032 * editfns.c (Finsert_char):
15033 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
15035 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
15037 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
15039 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
15041 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
15042 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
15044 * fileio.c: Don't assume EMACS_INT fits in off_t.
15045 (emacs_lseek): New static function.
15046 (Finsert_file_contents, Fwrite_region): Use it.
15047 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
15049 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
15051 * fns.c: Don't overflow int when computing a list length.
15052 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
15053 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
15054 truncation on 64-bit hosts. Check for QUIT every
15055 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
15056 faster and is responsive enough.
15057 (Flength): Report an error instead of overflowing an integer.
15058 (Fsafe_length): Return a float if the value is not representable
15059 as a fixnum. This shouldn't happen except in contrived situations.
15060 (Fnthcdr, Fsort): Don't assume list length fits in int.
15061 (Fcopy_sequence): Don't assume vector length fits in int.
15063 * alloc.c: Check that resized vectors' lengths fit in fixnums.
15064 (header_size, word_size): New constants.
15065 (allocate_vectorlike): Don't check size overflow here.
15066 (allocate_vector): Check it here instead, since this is the only
15067 caller of allocate_vectorlike that could cause overflow.
15068 Check that the new vector's length is representable as a fixnum.
15070 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
15071 The previous code was bogus. For example, next_almost_prime (32)
15072 returned 39, which is undesirable as it is a multiple of 3; and
15073 next_almost_prime (24) returned 25, which is a multiple of 5 so
15074 why was the code bothering to check for multiples of 7?
15076 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
15078 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
15080 Variadic C functions now count arguments with ptrdiff_t.
15081 This partly undoes my 2011-03-30 change, which replaced int with size_t.
15082 Back then I didn't know that the Emacs coding style prefers signed int.
15083 Also, in the meantime I found a few more instances where arguments
15084 were being counted with int, which may truncate counts on 64-bit
15085 machines, or EMACS_INT, which may be unnecessarily wide.
15086 * lisp.h (struct Lisp_Subr.function.aMANY)
15087 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
15088 Arg counts are now ptrdiff_t, not size_t.
15089 All variadic functions and their callers changed accordingly.
15090 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
15091 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
15092 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
15093 * callint.c (Fcall_interactively): Check arg count for overflow,
15094 to avoid potential buffer overrun. Use signed char, not 'int',
15095 for 'varies' array, so that we needn't bother to check its size
15096 calculation for overflow.
15097 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
15098 * eval.c (apply_lambda):
15099 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
15100 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
15101 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
15103 * callint.c (Fcall_interactively): Don't use index var as event count.
15105 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
15106 * mem-limits.h (SIZE): Remove; no longer used.
15108 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
15110 Remove unnecessary casts.
15111 * xterm.c (x_term_init):
15112 * xfns.c (x_set_border_pixel):
15113 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
15114 These aren't needed now that we assume ANSI C.
15116 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
15117 It's more likely to cause problems (due to unsigned overflow)
15120 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
15122 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
15124 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
15126 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
15128 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
15130 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
15132 GLYPH_CODE_FACE returns EMACS_INT, not int.
15133 * dispextern.h (merge_faces):
15134 * xfaces.c (merge_faces):
15135 * xdisp.c (get_next_display_element, next_element_from_display_vector):
15136 Don't assume EMACS_INT fits in int.
15138 * character.h (CHAR_VALID_P): Remove unused parameter.
15139 * fontset.c, lisp.h, xdisp.c: All uses changed.
15141 * editfns.c (Ftranslate_region_internal): Omit redundant test.
15143 * fns.c (concat): Minor tuning based on overflow analysis.
15144 This doesn't fix any bugs. Use int to hold character, instead
15145 of constantly refetching from Emacs object. Use XFASTINT, not
15146 XINT, for value known to be a character. Don't bother comparing
15147 a single byte to 0400, as it's always less.
15149 * floatfns.c (Fexpt):
15150 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
15152 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
15155 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
15157 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
15158 Without this fix, on a 64-bit host (aset S 0 4294967386) would
15159 incorrectly succeed when S was a string, because 4294967386 was
15160 truncated before it was used.
15162 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
15163 Otherwise, an out-of-range integer could cause undefined behavior
15166 * composite.c: Use int, not EMACS_INT, for characters.
15167 (fill_gstring_body, composition_compute_stop_pos): Use int, not
15168 EMACS_INT, for values that are known to be in character range.
15169 This doesn't fix any bugs but is the usual style inside Emacs and
15170 may generate better code on 32-bit machines.
15172 Make sure a 64-bit char is never passed to ENCODE_CHAR.
15173 This is for reasons similar to the recent CHAR_STRING fix.
15174 * charset.c (Fencode_char): Check that character arg is actually
15175 a character. Pass an int to ENCODE_CHAR.
15176 * charset.h (ENCODE_CHAR): Verify that the character argument is no
15177 wider than 'int', as a compile-time check to prevent future regressions
15180 * character.c (char_string): Remove unnecessary casts.
15182 Make sure a 64-bit char is never passed to CHAR_STRING.
15183 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
15184 by silently ignoring the top 32 bits, allowing some values
15185 that were far too large to be valid characters.
15186 * character.h: Include <verify.h>.
15187 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
15188 arguments are no wider than unsigned, as a compile-time check
15189 to prevent future regressions in this area.
15191 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
15192 (Fsubst_char_in_region):
15194 * xdisp.c (decode_mode_spec_coding):
15195 Adjust to CHAR_STRING's new requirement.
15196 * editfns.c (Finsert_char, Fsubst_char_in_region):
15197 * fns.c (concat): Check that character args are actually
15198 characters. Without this test, these functions did the wrong
15199 thing with wildly out-of-range values on 64-bit hosts.
15201 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
15202 These casts should not be needed on 32-bit hosts, either.
15203 * keyboard.c (read_char):
15204 * lread.c (Fload): Remove casts to unsigned.
15206 * lisp.h (UNSIGNED_CMP): New macro.
15207 This fixes comparison bugs on 64-bit hosts.
15208 (ASCII_CHAR_P): Use it.
15209 * casefiddle.c (casify_object):
15210 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
15211 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
15212 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
15213 * dispextern.h (FACE_FROM_ID):
15214 * keyboard.c (read_char): Use UNSIGNED_CMP.
15216 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
15217 not to EMACS_INT, to avoid GCC warning.
15219 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
15221 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
15222 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
15223 isn't needed on 32-bit machines.
15225 * buffer.c (Fgenerate_new_buffer_name):
15226 Use EMACS_INT for count, not int.
15227 (advance_to_char_boundary): Return EMACS_INT, not int.
15229 * data.c (Qcompiled_function): Now static.
15231 * window.c (window_body_lines): Now static.

15858 instead of using explicit *_CHAR codes.
15859 (bidi_resolve_explicit, bidi_resolve_weak):

15868 (bidi_level_of_next_char): Don't try to lookup the cache for the
15869 next/previous character if nothing is cached there yet, or if we
15870 were just reseat()'ed to a new position.
15872 * xdisp.c (set_cursor_from_row): Set start and stop points
15873 according to the row's direction when priming the loop that looks
15874 for the glyph on which to display cursor.

15876 (display_prop_intangible_p): Reimplement to call
15877 handle_display_spec instead of single_display_spec_intangible_p.
15878 Accept 3 additional arguments needed by handle_display_spec.
15879 This fixes incorrect cursor motion across display property with complex
15880 values: lists, `(when COND...)' forms, etc.

15882 lists with the argument STRING its top-level element.
15883 (display_prop_string_p): Fix the condition for processing a

15887 (compute_display_string_pos): Accept additional argument
15888 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
15889 value of a `display' property is a "replacing spec".
15890 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
15891 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
15892 the display property, but just return a value indicating whether
15893 the display property will replace the characters it covers.
15894 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
15895 frame_window_p members of struct bidi_it.
15896 (compute_display_string_pos, compute_display_string_end):

15919 All callers changed. (Bug#8762)
15921 * gnutls.c: Use Emacs's memory allocators.
15922 Without this change, the gnutls library would invoke malloc etc.
15923 directly, which causes problems on non-SYNC_INPUT hosts, and which
15924 runs afoul of improving memory_full behavior. (Bug#8761)
15925 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
15926 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
15927 xfree instead of the default malloc, realloc, free.
15928 (Fgnutls_boot): No need to check for memory allocation failure,
15929 since xmalloc does that for us.

15951 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
15952 for hashes and hash indexes, instead of 'unsigned' and 'int'.
15953 * alloc.c (allocate_vectorlike):
15954 Check for overflow in vector size calculations.
15955 * ccl.c (ccl_driver):
15956 Check for overflow when converting EMACS_INT to int.

15958 need to be updated by these changes.
15959 * fns.c (make_hash_table, maybe_resize_hash_table):
15960 Check for integer overflow with large hash tables.
15961 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
15962 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
15963 (SXHASH_REDUCE): New macro.
15964 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
15965 Use it instead of discarding useful hash info with large hash values.
15966 (sxhash_float): New function.
15967 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
15968 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
15969 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
15970 Rewrite to use FIXNUM_BITS, as this simplifies things.
15971 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
15972 Adjust signatures to match updated version of code.
15973 (consing_since_gc): Now EMACS_INT, since a single hash table can
15974 use more than INT_MAX bytes.

16023 Make it possible to run ./temacs.
16025 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
16026 syms_of_callproc does the same thing. Remove test for

16087 * fns.c (to_uchar): Define.
16088 (crypto_hash_function): Use it to convert some newly-signed

16102 to hold a serial number that is too large for a fixnum.
16103 (Fdbus_method_return_internal, Fdbus_method_error_internal):
16104 Check for serial numbers out of range. Decode any serial number
16105 that was so large that it became a float. (Bug#8722)
16107 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
16108 (Fdbus_call_method, Fdbus_call_method_asynchronously):
16109 Use XFASTINT rather than XUINT when numbers are nonnegative.
16110 (xd_append_arg, Fdbus_method_return_internal):
16111 (Fdbus_method_error_internal): Likewise. Also, for unsigned
16112 arguments, check that Lisp number is nonnegative, rather than
16113 silently wrapping negative numbers around. (Bug#8722)
16114 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
16117 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
16119 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
16121 ccl: Add integer overflow checks.
16122 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
16123 (IN_INT_RANGE): New macros.
16124 (ccl_driver): Use them to check for integer overflow when
16125 decoding a CCL program. Many of the new checks are whether XINT (x)
16126 fits in int; it doesn't always, on 64-bit hosts. The new version
16127 doesn't catch all possible integer overflows, but it's an
16128 improvement. (Bug#8719)
16130 * alloc.c (make_event_array): Use XINT, not XUINT.
16131 There's no need for unsigned here.
16133 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
16134 This follows up to the 2011-05-06 change that substituted uintptr_t
16135 for EMACS_INT. This case wasn't caught back then.
16137 Rework Fformat to avoid integer overflow issues.
16138 * editfns.c: Include <float.h> unconditionally, as it's everywhere
16139 now (part of C89). Include <verify.h>.
16140 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
16141 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
16142 (Fformat): Avoid the prepass trying to compute sizes; it was only
16143 approximate and thus did not catch overflow reliably. Instead, walk
16144 through the format just once, formatting and computing sizes as we go,
16145 checking for integer overflow at every step, and allocating a larger
16146 buffer as needed. Keep track separately whether the format is
16147 multibyte. Keep only the most-recently calculated precision, rather
16148 than them all. Record whether each argument has been converted to
16149 string. Use EMACS_INT, not int, for byte and char and arg counts.
16150 Support field widths and precisions larger than INT_MAX. Avoid
16151 sprintf's undefined behavior with conversion specifications such as %#d
16152 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
16153 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
16154 formatting out-of-range floating point numbers with int
16155 formats. (Bug#8668)
16157 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
16159 * data.c: Avoid integer truncation in expressions involving floats.
16160 * data.c: Include <intprops.h>.
16161 (arith_driver): When there's an integer overflow in an expression
16162 involving floating point, convert the integers to floating point
16163 so that the resulting value does not suffer from catastrophic
16164 integer truncation. For example, on a 64-bit host (* 4
16165 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
16166 Do not rely on undefined behavior after integer overflow.
16168 merge count_size_as_multibyte, parse_str_to_multibyte
16169 * character.c, character.h (count_size_as_multibyte):
16170 Rename from parse_str_to_multibyte; all uses changed.
16171 Check for integer overflow.
16172 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
16173 since it's now a duplicate of the other. This is more of
16174 a character than a buffer op, so better that it's in character.c.
16175 * fns.c, print.c: Adjust to above changes.
16177 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
16179 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
16181 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
16183 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
16184 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
16185 (x_clipboard_manager_save): Now static.
16186 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
16188 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
16189 (crypto_hash_function): Now static.
16190 Fix pointer signedness problems. Avoid unnecessary initializations.
16192 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
16194 * termhooks.h (Vselection_alist): Make it terminal-local.
16196 * terminal.c (create_terminal): Initialize it.
16198 * xselect.c: Support for clipboard managers.
16199 (Vselection_alist): Move to termhooks.h as terminal-local var.
16200 (LOCAL_SELECTION): New macro.
16201 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
16202 (symbol_to_x_atom): Remove gratuitous arg.
16203 (x_handle_selection_request, lisp_data_to_selection_data)
16204 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
16205 (x_own_selection, x_get_local_selection, x_convert_selection):
16206 New arg, specifying work frame. Use terminal-local Vselection_alist.
16207 (some_frame_on_display): Delete unused function.
16208 (Fx_own_selection_internal, Fx_get_selection_internal)
16209 (Fx_disown_selection_internal, Fx_selection_owner_p)
16210 (Fx_selection_exists_p): New optional frame arg.
16211 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
16212 (x_handle_selection_clear): Don't treat other terminals with the
16213 same keyboard specially. Use the terminal-local Vselection_alist.
16214 (x_clear_frame_selections): Use Frun_hook_with_args.
16216 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
16218 * xterm.h: Add support for those atoms.
16220 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
16222 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
16223 (converted_selections, conversion_fail_tag): New global variables.
16224 (x_selection_request_lisp_error): Free the above.
16225 (x_get_local_selection): Remove unnecessary code.
16226 (x_reply_selection_request): Args changed; handle arbitrary array
16227 of converted selections stored in converted_selections.
16228 Separate the XChangeProperty and SelectionNotify steps.
16229 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
16230 (x_convert_selection): New function.
16231 (x_handle_selection_event): Simplify.
16232 (x_get_foreign_selection): Don't ignore incoming requests while
16233 waiting for an answer; this will fail when we implement
16234 SAVE_TARGETS, and seems unnecessary anyway.
16235 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
16236 (Vx_sent_selection_functions): Doc fix.
16238 2011-05-26 Leo Liu <sdl.web@gmail.com>
16240 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
16242 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16244 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
16246 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
16247 for fringe update if it has periodic bitmap.
16248 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
16249 and fringe_bitmap_periodic_p.
16251 * fringe.c (get_fringe_bitmap_data): New function.
16252 (draw_fringe_bitmap_1, update_window_fringes): Use it.
16253 (update_window_fringes): Record periodicity of fringe bitmap in glyph
16254 row. Mark glyph row for fringe update if periodicity changed.
16256 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
16257 for fringe update unless it has periodic bitmap.
16259 2011-05-25 Kenichi Handa <handa@m17n.org>
16261 * xdisp.c (get_next_display_element): Set correct it->face_id for
16262 a static composition.
16264 2011-05-24 Leo Liu <sdl.web@gmail.com>
16267 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
16269 * fns.c (crypto_hash_function, Fsha1): New function.
16270 (Fmd5): Use crypto_hash_function.
16271 (syms_of_fns): Add Ssha1.
16273 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
16275 * gnutls.c: Remove unused macros.
16276 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
16277 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
16278 Remove macros that are defined and never used.
16279 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
16281 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
16283 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
16284 (Fx_get_selection_internal): Minor cleanup.
16285 (Fx_own_selection_internal): Rename arguments for consistency with
16288 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
16290 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
16292 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
16294 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
16296 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16298 * dispnew.c (scrolling_window): Don't exclude the case that the
16299 last enabled row in the desired matrix touches the bottom boundary.
16301 2011-05-21 Glenn Morris <rgm@gnu.org>
16303 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
16304 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
16305 and add some more files.
16307 2011-05-20 Eli Zaretskii <eliz@gnu.org>
16309 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
16310 report_file_error introduced by the change from 2011-05-07.
16312 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
16314 * systime.h (Time): Define only if emacs is defined.
16315 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
16316 where the include path doesn't have X11/X.h by default. See
16317 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
16319 2011-05-20 Kenichi Handa <handa@m17n.org>
16321 * composite.c (find_automatic_composition): Fix previous change.
16323 2011-05-20 Glenn Morris <rgm@gnu.org>
16325 * lisp.mk: New file, split from Makefile.in.
16326 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
16327 (shortlisp): Remove.
16328 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
16330 2011-05-19 Glenn Morris <rgm@gnu.org>
16332 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
16333 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
16334 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
16335 (lisp): Set the order to that of loadup.el.
16336 (shortlisp): Make it a copy of $lisp.
16337 (SOME_MACHINE_LISP): Remove.
16338 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
16339 Use just $shortlisp, not $SOME_MACHINE_LISP too.
16341 2011-05-18 Kenichi Handa <handa@m17n.org>
16343 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
16344 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
16345 (find_automatic_composition): Mostly rewrite for efficiency.
16347 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
16349 * makefile.w32-in: Update dependencies.
16351 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
16353 * menu.c: Include limits.h (fixes the MS-Windows build broken by
16354 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
16356 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
16358 Fix some integer overflow issues, such as string length overflow.
16360 * insdel.c (count_size_as_multibyte): Check for string overflow.
16362 * character.c (lisp_string_width): Check for string overflow.
16363 Use EMACS_INT, not int, for string indexes and lengths; in
16364 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
16365 the resulting string length overflows an EMACS_INT; instead,
16366 report a string overflow if no precision given. When checking for
16367 precision exhaustion, use a check that cannot possibly have
16368 integer overflow. (Bug#8675)
16369 * character.h (lisp_string_width): Adjust to new signature.
16371 * alloc.c (string_overflow): New function.
16372 (Fmake_string): Use it. This doesn't change behavior, but saves
16373 a few bytes and will simplify future changes.
16374 * character.c (string_escape_byte8): Likewise.
16375 * lisp.h (string_overflow): New decl.
16377 Fixups, following up to the user-interface timestamp change.
16378 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
16379 for UI timestamps, instead of unsigned long.
16380 * msdos.c (mouse_get_pos): Likewise.
16381 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
16382 * w32gui.h (Time): Define by including "systime.h" rather than by
16383 declaring it ourselves. (Bug#8664)
16385 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
16386 * image.c (clear_image_cache): Likewise.
16388 * term.c (term_mouse_position): Don't assume time_t wraparound.
16390 Be more systematic about user-interface timestamps.
16391 Before, the code sometimes used 'Time', sometimes 'unsigned long',
16392 and sometimes 'EMACS_UINT', to represent these timestamps.
16393 This change causes it to use 'Time' uniformly, as that's what X uses.
16394 This makes the code easier to follow, and makes it easier to catch
16395 integer overflow bugs such as Bug#8664.
16396 * frame.c (Fmouse_position, Fmouse_pixel_position):
16397 Use Time, not unsigned long, for user-interface timestamps.
16398 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
16399 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
16400 * keyboard.h (last_event_timestamp): Likewise.
16401 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
16402 * menu.h (xmenu_show): Likewise.
16403 * term.c (term_mouse_position): Likewise.
16404 * termhooks.h (struct input_event.timestamp): Likewise.
16405 (struct terminal.mouse_position_hook): Likewise.
16406 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
16407 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
16408 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
16409 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
16410 what it was before.
16411 * menu.h, termhooks.h: Include "systime.h", for Time.
16413 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
16414 Don't assume that the difference between two unsigned long values
16415 can fit into an integer. At this point, we know button_down_time
16416 <= event->timestamp, so the difference must be nonnegative, so
16417 there's no need to cast the result if double-click-time is
16418 nonnegative, as it should be; check that it's nonnegative, just in
16419 case. This bug is triggered when events are more than 2**31 ms
16420 apart (about 25 days). (Bug#8664)
16422 * xselect.c (last_event_timestamp): Remove duplicate decl.
16423 (x_own_selection): Remove needless cast to unsigned long.
16425 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
16426 that always fit in int. Use a sentinel instead of a counter, to
16427 avoid a temp and to allay GCC's concerns about possible int overflow.
16428 * frame.h (struct frame): Use int for menu_bar_items_used
16429 instead of EMACS_INT, since it always fits in int.
16431 * menu.c (grow_menu_items): Check for int overflow.
16433 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
16435 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
16436 Before, the code was not consistent. These values cannot exceed
16437 2**31 - 1 so there's no need to make them unsigned.
16438 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
16439 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
16440 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
16442 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
16444 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
16445 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
16446 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
16447 presumably because the widths might not match.
16449 * window.c (size_window): Avoid needless test at loop start.
16451 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
16453 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
16455 2011-05-12 Drew Adams <drew.adams@oracle.com>
16457 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
16459 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16461 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
16462 `width' to `bar_area_x' and `bar_area_width', respectively.
16463 (x_scroll_run): Take account of fringe background extension.
16465 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
16466 Rename local vars `left' and `width' to `bar_area_x' and
16467 `bar_area_width', respectively.
16468 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
16469 background extension.
16471 2011-05-10 Jim Meyering <meyering@redhat.com>
16473 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
16475 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
16477 * image.c (Finit_image_library): Return t for built-in image types,
16478 like pbm and xbm. (Bug#8640)
16480 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
16482 * w32menu.c (set_frame_menubar): Fix submenu allocation.
16484 2011-05-07 Eli Zaretskii <eliz@gnu.org>
16486 * w32console.c (Fset_screen_color): Doc fix.
16487 (Fget_screen_color): New function.
16488 (syms_of_ntterm): Defsubr it.
16490 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
16491 unlink the temporary file if Fcall_process didn't create it in the
16493 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
16494 child process will be redirected to a file specified with `:file'.
16495 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
16496 cue to call_process_cleanup not to close that handle.
16498 2011-05-07 Ben Key <bkey76@gmail.com>
16500 * makefile.w32-in: The bootstrap-temacs rule now makes use of
16501 one of two shell specific rules, either bootstrap-temacs-CMD or
16502 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
16503 to the previous implementation of the bootstrap-temacs rule.
16504 The bootstrap-temacs-CMD rule is similar to the previous
16505 implementation of the bootstrap-temacs rule except that it
16506 makes use of the ESC_CFLAGS variable instead of the CFLAGS
16509 These changes, along with some changes to nt/configure.bat,
16510 nt/gmake.defs, and nt/nmake.defs, are required to extend my
16511 earlier fix to add support for --cflags and --ldflags options
16512 that include quotes so that it works whether make uses cmd or
16515 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
16517 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
16518 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
16520 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
16521 a string. Handle both cases.
16522 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
16523 (Fdbus_register_method): Use Qinvalid_function.
16525 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
16527 * makefile.w32-in: Update dependencies.
16528 (LISP_H): Add inttypes.h and stdin.h.
16529 (PROCESS_H): Add unistd.h.
16531 2011-05-06 Eli Zaretskii <eliz@gnu.org>
16533 * lread.c: Include limits.h (fixes the MS-Windows build broken by
16534 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
16536 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
16538 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
16540 * term.c (vfatal): Remove stray call to va_end.
16541 It's not needed and the C Standard doesn't allow it here anyway.
16543 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
16544 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
16546 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
16549 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
16551 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16553 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
16555 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
16557 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
16559 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
16560 * charset.c (Fdefine_charset_internal): Don't initialize
16561 charset.code_space[15]. The value was garbage, on hosts with
16562 32-bit int (Bug#8600).
16564 * lread.c (read_integer): Be more consistent with string-to-number.
16565 Use string_to_number to do the actual conversion; this avoids
16566 rounding errors and fixes some other screwups. Without this fix,
16567 for example, #x1fffffffffffffff was misread as -2305843009213693952.
16568 (digit_to_number): Move earlier, for benefit of read_integer.
16569 Return -1 if the digit is out of range for the base, -2 if it is
16570 not a digit in any supported base. (Bug#8602)
16572 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
16574 * dispnew.c (scrolling_window): Return 1 if we scrolled,
16575 to match comment at start of function. This also removes a
16576 GCC warning about overflow in a 32+64-bit port.
16578 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
16580 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
16581 Reported by Stefan Monnier in
16582 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
16583 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
16584 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
16586 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
16587 (EMACS_UINTPTR): Likewise, with uintptr_t.
16589 * lisp.h: Prefer 64-bit EMACS_INT if available.
16590 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
16591 on 32-bit hosts that have 64-bit int, so that they can access
16593 However, temporarily disable this change unless the temporary
16594 symbol WIDE_EMACS_INT is defined.
16596 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
16598 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
16599 This removes an assumption that EMACS_INT and long are the same
16600 width as pointers. The assumption is true for Emacs porting targets
16601 now, but we want to make other targets possible.
16602 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
16603 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
16604 In the rest of the code, change types of integers that hold casted
16605 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
16606 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
16607 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
16608 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
16609 No need to cast type when ORing.
16610 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
16611 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
16612 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
16613 assume EMACS_INT is the same width as char *.
16614 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
16615 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
16616 Remove no-longer-needed casts.
16617 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
16618 (xg_tool_bar_help_callback, xg_make_tool_item):
16619 Use EMACS_INTPTR to hold an integer
16620 that will be cast to void *; this can avoid a GCC warning
16621 if EMACS_INT is not the same width as void *.
16622 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
16623 * xdisp.c (display_echo_area_1, resize_mini_window_1):
16624 (current_message_1, set_message_1):
16625 Use a local to convert to proper width without a cast.
16626 * xmenu.c (dialog_selection_callback): Likewise.
16628 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
16629 Also, don't assume VALBITS / RAND_BITS is less than 5,
16630 and don't rely on undefined behavior when shifting a 1 left into
16632 * lisp.h (get_random): Change signature to match.
16634 * lread.c (hash_string): Use size_t, not int, for hash computation.
16635 Normally we prefer signed values; but hashing is special, because
16636 it's better to use unsigned division on hash table sizes so that
16637 the remainder is nonnegative. Also, size_t is the natural width
16638 for hashing into memory. The previous code used 'int', which doesn't
16639 retain enough info to hash well into very large tables.
16640 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
16642 * dbusbind.c: Don't possibly lose pointer info when converting.
16643 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
16644 Use XPNTR rather than XHASH, so that the high-order bits of
16645 the pointer aren't lost when converting through void *.
16647 * eval.c (Fautoload): Don't double-shift a pointer.
16649 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
16651 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
16653 * gnutls.c (DEF_GNUTLS_FN):
16654 * image.c (DEF_IMGLIB_FN): Make function pointers static.
16656 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
16658 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
16661 2011-05-05 Eli Zaretskii <eliz@gnu.org>
16663 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
16664 New version that can reserve upto 2GB of heap space.
16666 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
16668 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
16670 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
16672 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
16673 `gnutls_certificate_set_x509_key_file'.
16675 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
16677 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
16678 Update dependencies.
16680 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
16682 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
16683 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
16684 Remove unused parameter `fildes'.
16685 * process.c (read_process_output, send_process): Don't pass it.
16687 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
16689 Fix previous change: the library cache is defined in w32.c.
16690 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
16691 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
16693 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
16695 Implement dynamic loading of GnuTLS on Windows.
16697 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
16698 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
16699 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
16702 * gnutls.c (Qgnutls_dll): Define.
16703 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
16704 (gnutls_*): Declare function pointers.
16705 (init_gnutls_functions): New function to initialize function pointers.

16708 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
16709 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
16710 (emacs_gnutls_write, emacs_gnutls_read)
16711 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
16712 (Fgnutls_available_p): New function.
16713 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

16720 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
16721 (w32_delayed_load): Move to w32.c.
16723 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
16725 * w32.c (QCloaded_from, Vlibrary_cache): Define.
16726 (w32_delayed_load): Move from image.c. When loading a library, record
16727 its filename in the :loaded-from property of the library id.
16728 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
16729 Initialize and staticpro them.
16730 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
16732 * process.c: Include lisp.h before w32.h, not after.
16733 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
16734 instead of gnutls_record_check_pending.
16736 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
16738 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
16740 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
16741 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
16744 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
16746 * xterm.c (x_set_frame_alpha): Do not set property on anything
16747 else than FRAME_X_OUTER_WINDOW (Bug#8608).
16749 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
16751 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
16753 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
16755 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
16756 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

16769 * sysdep.c (wait_for_termination_1): Make static.
16770 (wait_for_termination, interruptible_wait_for_termination):
16771 Move after wait_for_termination_1.
16773 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
16775 * sysdep.c (interruptible_wait_for_termination): New function
16776 which is like wait_for_termination, but allows keyboard
16779 * callproc.c (Fcall_process): Add (:file "file") as an option for
16781 (Fcall_process_region): Ditto.
16783 2011-04-30 Eli Zaretskii <eliz@gnu.org>
16785 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
16786 rather than `XVECTOR (FOO)->size'.
16788 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
16789 inttypes.h, as a gnulib replacement is used if it not available in
16792 2011-04-21 Eli Zaretskii <eliz@gnu.org>
16794 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
16795 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
16796 of MOST_POSITIVE_FIXNUM. (Bug#8528)
16798 * coding.c (coding_alloc_by_realloc): Error out if destination
16799 will grow beyond MOST_POSITIVE_FIXNUM.
16800 (decode_coding_emacs_mule): Abort if there isn't enough place in
16801 charbuf for the composition carryover bytes. Reserve an extra
16802 space for up to 2 characters produced in a loop.
16803 (decode_coding_iso_2022): Abort if there isn't enough place in
16804 charbuf for the composition carryover bytes.
16806 2011-04-21 Eli Zaretskii <eliz@gnu.org>
16808 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
16809 aborting when %lld or %lll format is passed.
16810 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
16811 %llo or %llx format is passed. (Bug#8545)
16813 * window.c (window_scroll_line_based): Use a marker instead of
16814 simple variables to record original value of point. (Bug#7952)
16816 * doprnt.c (doprnt): Fix the case where a multibyte sequence
16817 produced by %s or %c overflows available buffer space. (Bug#8545)
16819 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
16821 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
16822 (SIZE_MAX): Move defn after all includes, as they might #define it.
16824 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
16826 * w32.c (init_environment): Warn about defaulting HOME to C:\.
16828 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
16830 * keyboard.c (Qdelayed_warnings_hook): Define.
16831 (command_loop_1): Run `delayed-warnings-hook'
16832 if Vdelayed_warnings_list is non-nil.
16833 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
16834 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
16836 2011-04-28 Eli Zaretskii <eliz@gnu.org>
16838 * doprnt.c (doprnt): Don't return value smaller than the buffer
16839 size if the message was truncated. (Bug#8545).
16841 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
16843 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
16844 (Fx_window_property): #if-0 the whole functions, not just the bodies.
16846 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
16848 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
16850 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
16852 * makefile.w32-in: Update dependencies.
16854 2011-04-27 Eli Zaretskii <eliz@gnu.org>
16856 Improve `doprnt' and its usage. (Bug#8545)
16857 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
16858 `format_end'. Remove support for %l as a conversion specifier.
16859 Don't use xrealloc. Improve diagnostics when the %l size modifier
16860 is used. Update the commentary.
16862 * eval.c (verror): Simplify calculation of size_t.
16864 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
16867 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
16869 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
16872 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
16874 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
16875 This makes this file independent of the recent pseudovector change.
16877 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
16879 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
16881 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
16882 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
16883 Remove unused local.
16884 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
16886 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
16887 GCC 4.6.0 optimizes based on type-based alias analysis.
16888 For example, if b is of type struct buffer * and v of type struct
16889 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
16890 != &v->size, and therefore "v->size = 1; b->size = 2; return
16891 v->size;" must therefore return 1. This assumption is incorrect
16892 for Emacs, since it type-puns struct Lisp_Vector * with many other
16893 types. To fix this problem, this patch adds a new type struct
16894 vectorlike_header that documents the constraints on layout of vectors
16895 and pseudovectors, and helps optimizing compilers not get fooled
16896 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
16897 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
16898 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
16900 (XSETPVECTYPE): Rewrite in terms of new macro.
16901 (XSETPVECTYPESIZE): New macro, specifying both type and size.
16902 This is a bit clearer, and further avoids the possibility of
16903 undesirable aliasing.
16904 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
16905 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
16906 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
16907 since Lisp_Subr is a special case (no "next" field).
16908 (ASIZE): Now uses header.size rather than size.
16909 All previous uses of XVECTOR (foo)->size replaced to use this macro,
16910 to avoid the hassle of writing XVECTOR (foo)->header.size.
16911 (struct vectorlike_header): New type.
16912 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
16913 object, to help avoid aliasing.
16914 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
16915 (SUBRP): Likewise, since Lisp_Subr is a special case.
16916 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
16917 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
16918 (struct Lisp_Hash_Table): Combine first two members into a single
16919 struct vectorlike_header member. All uses of "size" and "next" members
16920 changed to be "header.size" and "header.next".
16921 * buffer.h (struct buffer): Likewise.
16922 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
16923 * frame.h (struct frame): Likewise.
16924 * process.h (struct Lisp_Process): Likewise.
16925 * termhooks.h (struct terminal): Likewise.
16926 * window.c (struct save_window_data, struct saved_window): Likewise.
16927 * window.h (struct window): Likewise.
16928 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
16929 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
16930 * buffer.c (init_buffer_once): Likewise.
16931 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
16933 * process.c (Fformat_network_address): Use local var for size,
16936 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
16938 Make the Lisp reader and string-to-float more consistent (Bug#8525)
16939 * data.c (atof): Remove decl; no longer used or needed.
16940 (digit_to_number): Move to lread.c.
16941 (Fstring_to_number): Use new string_to_number function, to be
16942 consistent with how the Lisp reader treats infinities and NaNs.
16943 Do not assume that floating-point numbers represent EMACS_INT
16944 without losing information; this is not true on most 64-bit hosts.
16945 Avoid double-rounding errors, by insisting on integers when
16946 parsing non-base-10 numbers, as the documentation specifies.
16947 * lisp.h (string_to_number): New decl, replacing ...
16948 (isfloat_string): Remove.
16949 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
16950 (read1): Do not accept +. and -. as integers; this
16951 appears to have been a coding error. Similarly, do not accept
16952 strings like +-1e0 as floating point numbers. Do not report
16953 overflow for integer overflows unless the base is not 10 which
16954 means we have no simple and reliable way to continue.
16955 Break out the floating-point parsing into a new
16956 function string_to_number, so that Fstring_to_number parses
16957 floating point numbers consistently with the Lisp reader.
16958 (digit_to_number): Move here from data.c. Make it static inline.
16959 (E_CHAR, EXP_INT): Remove, replacing with ...
16960 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
16961 (string_to_number): New function, replacing isfloat_string.
16962 This function checks for valid syntax and produces the resulting
16963 Lisp float number too. Rework it so that string-to-number
16964 no longer mishandles examples like "1.0e+". Use strtoumax,
16965 so that overflow for non-base-10 numbers is reported only when
16966 there's no portable and simple way to convert to floating point.
16968 * textprop.c (set_text_properties_1): Rewrite for clarity,
16969 and to avoid GCC warning about integer overflow.
16971 * intervals.h (struct interval): Use EMACS_INT for members
16972 where EMACS_UINT might cause problems. See
16973 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
16974 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
16975 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
16977 (offset_intervals): Tell GCC not to worry about length overflow
16978 when negating a negative length.
16980 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
16981 (overrun_check_free): Likewise.
16983 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
16984 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
16987 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
16988 (gnutls_make_error): Rename local to avoid shadowing.
16989 (gnutls_emacs_global_deinit): ifdef out; not used.
16990 (Fgnutls_boot): Use const for pointer to readonly storage.
16991 Comment out unused local. Fix pointer signedness problems.
16993 * lread.c (openp): Don't stuff size_t into an 'int'.
16994 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
16995 about possible signed overflow.
16997 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
16998 (GDK_KEY_g): Don't define if already defined.
16999 (xg_prepare_tooltip): Avoid pointer signedness problem.
17000 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
17002 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
17003 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
17005 * xfns.c (Fx_window_property): Simplify a bit,
17006 to make a bit faster and to avoid GCC 4.6.0 warning.
17007 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
17009 * fns.c (internal_equal): Don't assume size_t fits in int.
17011 * alloc.c (compact_small_strings): Tighten assertion a little.
17013 Replace pEd with more-general pI, and fix some printf arg casts.
17014 * lisp.h (pI): New macro, generalizing old pEd macro to other
17015 conversion specifiers. For example, use "...%"pI"d..." rather
17016 than "...%"pEd"...".
17017 (pEd): Remove. All uses replaced with similar uses of pI.
17018 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
17019 * alloc.c (check_pure_size): Don't overflow by converting size to int.
17020 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
17021 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
17022 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
17023 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
17024 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
17026 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
17027 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
17028 * print.c (safe_debug_print, print_object): Likewise.
17029 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
17031 Use pI instead of if-then-else-abort. Use %p to avoid casts,
17032 avoiding the 0 flag, which is not portable.
17033 * process.c (Fmake_network_process): Use pI to avoid cast.
17034 * region-cache.c (pp_cache): Likewise.
17035 * xdisp.c (decode_mode_spec): Likewise.
17036 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
17037 behavior on 64-bit hosts with printf arg.
17038 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
17039 (x_stop_queuing_selection_requests): Likewise.
17040 (x_get_window_property): Don't truncate byte count to an 'int'
17043 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
17044 here, since it parses constructs like leading '-' and spaces,
17045 which are not wanted; and it overflows with large numbers.
17046 Instead, simply match F[0-9]+, which is what is wanted anyway.
17048 * alloc.c: Remove unportable assumptions about struct layout.
17049 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
17050 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
17051 (allocate_vectorlike, make_pure_vector): Use the new macros,
17052 plus offsetof, to remove unportable assumptions about struct layout.
17053 These assumptions hold on all porting targets that I know of, but
17054 they are not guaranteed, they're easy to remove, and removing them
17055 makes further changes easier.
17057 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
17058 This doesn't fix a bug but makes the code clearer.
17059 (string_overrun_cookie): Now const. Use initializers that
17060 don't formally overflow signed char, to avoid warnings.
17061 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
17062 can cause Emacs to crash when string overrun checking is enabled.
17063 (allocate_buffer): Don't assume sizeof (struct buffer) is a
17064 multiple of sizeof (EMACS_INT); it need not be, if
17065 alignof(EMACS_INT) < sizeof (EMACS_INT).
17066 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
17068 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

17095 2011-04-25 Eli Zaretskii <eliz@gnu.org>
17097 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
17098 "cast to pointer from integer of different size".
17100 Improve doprnt and its use in verror. (Bug#8545)
17101 * doprnt.c (doprnt): Document the set of format control sequences
17102 supported by the function. Use SAFE_ALLOCA instead of always
17105 * eval.c (verror): Don't limit the buffer size at size_max-1, that
17106 is one byte too soon. Don't use xrealloc; instead xfree and
17109 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
17111 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the

17117 parameters of `gnutls-boot' and documented those parameters in the
17118 docstring. Start callback support.
17119 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake

17224 codepoint of an invalid character, to avoid displaying a bogus
17227 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to

17234 to `error' in error message about FINAL_CHAR argument. Make sure
17235 FINAL_CHAR is a character, and use %c when it is passed as
17236 argument to `error'.
17238 2011-04-23 Eli Zaretskii <eliz@gnu.org>
17240 * s/ms-w32.h (localtime): Redirect to sys_localtime.

17306 * dispextern.h (struct redisplay_interface): Rename param
17307 to avoid shadowing.
17308 * termhooks.h (struct terminal): Likewise.

17420 specify buffer/string position and length are now ssize_t and
17421 size_t. Return type is regoff_t.
17423 2011-04-16 Ben Key <bkey76@gmail.com>
17425 * nsfont.m: Fixed bugs in ns_get_family and
17426 ns_descriptor_to_entity that were caused by using free to
17427 deallocate memory blocks that were allocated by xmalloc (via

17847 Remove decls, since these functions are now static.
17848 (Funintern, Fget_internal_run_time): New decls, since these functions
17849 were already external.
17851 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

17859 Mark functions with DEFUE instead of DEFUN,
17860 if they are used in other modules.
17861 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
17862 decls for now-static functions.
17863 * buffer.h (Fdelete_overlay): Remove decl.

17899 2011-04-13 Eli Zaretskii <eliz@gnu.org>
17901 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
17902 when at ZV. (Bug#8487)
17904 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
17906 * charset.c (Fclear_charset_maps): Use xfree instead of free.
17908 * keyboard.c (parse_tool_bar_item): Likewise.
17909 * sound.c (sound_cleanup, alsa_close): Likewise.
17910 * termcap.c (tgetent): Likewise.
17911 * xfns.c (x_default_font_parameter): Likewise.
17912 * xsettings.c (read_and_apply_settings): Likewise.
17914 * alloc.c (overrun_check_malloc, overrun_check_realloc)
17915 (overrun_check_free): Protoize.
17917 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
17919 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
17920 since callers should never pass a negative size.
17921 Change the signature to match that of plain 'read' and 'write'; see
17922 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
17923 * lisp.h: Update prototypes of emacs_write and emacs_read.
17925 2011-04-11 Eli Zaretskii <eliz@gnu.org>
17927 * xdisp.c (redisplay_window): Don't try to determine the character
17928 position of the scroll margin if the window start point w->startp
17929 is outside the buffer's accessible region. (Bug#8468)
17931 2011-04-10 Eli Zaretskii <eliz@gnu.org>
17933 Fix write-region and its subroutines for buffers > 2GB.
17934 * fileio.c (a_write, e_write): Modify declaration of arguments and
17935 local variables to support buffers larger than 2GB.
17936 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
17938 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
17939 argument, local variables, and return value.
17941 * lisp.h: Update prototypes of emacs_write and emacs_read.
17943 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
17945 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
17947 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
17949 Fix more problems found by GCC 4.6.0's static checks.
17951 * xdisp.c (vmessage): Use a better test for character truncation.
17953 * charset.c (load_charset_map): <, not <=, for optimization,
17954 and to avoid potential problems with integer overflow.
17955 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
17956 * casetab.c (set_identity, shuffle): Likewise.
17957 * editfns.c (Fformat): Likewise.
17958 * syntax.c (skip_chars): Likewise.
17960 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
17961 This also lets GCC 4.6.0 generate slightly better loop code.
17963 * callint.c (Fcall_interactively): <, not <=, for optimization.
17964 (Fcall_interactively): Count the number of arguments produced,
17965 not the number of arguments given. This is simpler and lets GCC
17966 4.6.0 generate slightly better code.
17968 * ftfont.c: Distingish more carefully between FcChar8 and char.
17969 The previous code passed unsigned char * to a functions like
17970 strlen and xstrcasecmp that expect char *, which does not
17971 conform to the C standard.
17972 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
17973 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
17974 char * when the C standard requires it.
17976 * keyboard.c (read_char): Remove unused var.
17978 * eval.c: Port to Windows vsnprintf (Bug#8435).
17979 Include <limits.h>.
17980 (SIZE_MAX): Define if the headers do not.
17981 (verror): Do not give up if vsnprintf returns a negative count.
17982 Instead, grow the buffer. This ports to Windows vsnprintf, which
17983 does not conform to C99. Problem reported by Eli Zaretskii.
17984 Also, simplify the allocation scheme, by avoiding the need for
17985 calling realloc, and removing the ALLOCATED variable.
17987 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
17989 Remove invocations of doprnt, as Emacs now uses vsnprintf.
17990 But keep the doprint source code for now, as we might revamp it
17991 and use it again (Bug#8435).
17992 * lisp.h (doprnt): Remove.
17993 * Makefile.in (base_obj): Remove doprnt.o.
17994 * deps.mk (doprnt.o): Remove.
17996 error: Print 32- and 64-bit integers portably (Bug#8435).
17997 Without this change, on typical 64-bit hosts error ("...%d...", N)
17998 was used to print both 32- and 64-bit integers N, which relied on
17999 undefined behavior.
18000 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
18001 * lisp.h (error, verror): Mark as printf-like functions.
18002 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
18003 Report overflow in size calculations when allocating printf buffer.
18004 Do not truncate output string at its first null byte.
18005 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
18006 Truncate the output at a character boundary, since vsnprintf does not
18008 * charset.c (check_iso_charset_parameter): Convert internal
18009 character to string before calling 'error', since %c now has the
18011 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
18012 overflow when computing char to be passed to 'error'. Do not
18013 pass Lisp_Object to 'error'; pass the integer instead.
18014 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
18015 formatted with plain %d.
18017 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
18019 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
18021 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
18023 * xterm.c (x_catch_errors): Remove duplicate declaration.
18025 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
18027 * xdisp.c, lisp.h (message_nolog): Remove; unused.
18029 2011-04-10 Jim Meyering <meyering@redhat.com>
18031 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
18032 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
18033 return ssize_t not "int", and use size_t as the buffer length.
18034 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
18035 * gnutls.h: Update declarations.
18036 * process.c (read_process_output): Use ssize_t, to match.
18037 (send_process): Likewise.
18039 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
18041 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
18043 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
18045 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
18046 Use unsigned char, to match FcChar8 type definition.
18048 * xterm.c (handle_one_xevent):
18049 * xmenu.c (create_and_show_popup_menu):
18050 * xselect.c (x_decline_selection_request)
18051 (x_reply_selection_request): Avoid type-punned deref of X events.
18053 2011-04-09 Eli Zaretskii <eliz@gnu.org>
18055 Fix some uses of `int' instead of EMACS_INT.
18056 * search.c (string_match_1, fast_string_match)
18057 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
18058 (scan_buffer, find_next_newline_no_quit)
18059 (find_before_next_newline, search_command, Freplace_match)
18060 (Fmatch_data): Make some `int' variables be EMACS_INT.
18062 * xdisp.c (display_count_lines): 3rd argument and return value now
18063 EMACS_INT. All callers changed.
18064 (pint2hrstr): Last argument is now EMACS_INT.
18066 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
18067 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
18068 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

18079 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
18080 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
18082 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
18083 (encode_invocation_designation): Last argument P_NCHARS is now
18085 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
18086 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
18088 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
18091 * ccl.c (Fccl_execute_on_string): Declare some variables
18094 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
18096 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
18098 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
18100 * process.c (Fformat_network_address): Doc fix.
18102 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
18104 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
18106 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
18108 * keyboard.c (read_char): Call Lisp function help-form-show,
18109 instead of using internal_with_output_to_temp_buffer.
18110 (Qhelp_form_show): New var.
18111 (syms_of_keyboard): Use DEFSYM macro.
18113 * print.c (internal_with_output_to_temp_buffer): Function deleted.
18115 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
18117 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
18119 * process.c (Flist_processes): Remove to Lisp.
18120 (list_processes_1): Delete.

18124 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
18126 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
18128 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
18130 Fix more problems found by GCC 4.6.0's static checks.

18134 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
18136 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
18138 * xdisp.c (vmessage): Mark as a printf-like function.
18140 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
18142 * sound.c (sound_warning): Don't crash if arg contains a printf format.

18145 printf-like functions.
18146 (tiff_load): Add casts to remove these marks before passing them
18147 to system-supplied API.
18149 * eval.c (Fsignal): Remove excess argument to 'fatal'.
18151 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
18152 This avoids several warnings with gcc -Wstrict-overflow.
18153 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
18154 directly, rather than having caller test rule sign. This avoids
18155 some unnecessary tests.
18156 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
18157 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
18158 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
18160 * xfont.c (xfont_text_extents): Remove var that was set but not used.
18161 (xfont_open): Avoid unnecessary tests.
18163 * composite.c (composition_gstring_put_cache): Use unsigned integer.
18165 * composite.h, composite.c (composition_gstring_put_cache):
18166 Use EMACS_INT, not int, for length.

18172 by using the new macro.
18174 * textprop.c (set_text_properties_1): Change while to do-while,
18175 since the condition is always true at first.
18177 * intervals.c (graft_intervals_into_buffer): Mark var as used.
18178 (interval_deletion_adjustment): Return unsigned value.
18181 * process.c (list_processes_1, create_pty, read_process_output):

18191 (update_syntax_table): Use unsigned instead of int.
18193 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
18194 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
18195 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
18197 * print.c (print_error_message): Avoid int overflow.
18199 * font.c (font_list_entities): Redo for clarity,
18200 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
18202 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
18203 (font_score): Avoid potential overflow in diff calculation.
18205 * fns.c (substring_both): Remove var that is set but not used.
18206 (sxhash): Redo loop for clarity and to avoid wraparound warning.
18208 * eval.c (funcall_lambda): Rename local to avoid shadowing.
18210 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
18211 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
18212 can always succeed if overflow has undefined behavior.
18214 * search.c (boyer_moore, wordify): Remove vars set but not used.
18215 (wordify): Omit three unnecessary tests.
18217 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
18218 All callers changed. This avoids the need for an unused var.
18220 * casefiddle.c (casify_region): Remove var that is set but not used.
18222 * dired.c (file_name_completion): Remove var that is set but not used.
18224 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
18226 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
18227 (Finsert_file_contents): Remove unnecessary code checking fd.
18229 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
18230 Check for integer overflow on size calculations.
18232 * buffer.c (Fprevious_overlay_change): Remove var that is set
18235 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
18236 Remove vars that are set but not used.
18237 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
18238 (timer_check_2): Mark vars as initialized.
18240 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
18242 * image.c (lookup_image): Remove var that is set but not used.
18243 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
18245 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
18246 that are set but not used.
18248 * xfns.c (make_invisible_cursor): Don't return garbage
18249 if XCreateBitmapFromData fails (Bug#8410).
18251 * xselect.c (x_get_local_selection, x_handle_property_notify):
18252 Remove vars that are set but not used.
18254 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
18255 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
18257 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
18258 Remove var that is set but not used.

18260 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
18261 Check for overflow.
18263 * xfaces.c (realize_named_face): Remove vars that are set but not used.
18264 (map_tty_color) [!defined MSDOS]: Likewise.
18266 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
18268 * coding.c: Remove vars that are set but not used.
18269 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
18270 All callers changed.
18271 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
18272 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
18273 (decode_coding_charset): Remove vars that are set but not used.
18275 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
18276 that is set but not used.
18278 * print.c (print_object): Remove var that is set but not used.
18280 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
18281 The gnulib version avoids calling malloc in the usual case,
18282 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
18283 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
18284 * filelock.c (current_lock_owner): Likewise.
18285 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
18286 * sysdep.c: Include allocator.h, careadlinkat.h.
18287 (emacs_no_realloc_allocator): New static constant.
18288 (emacs_readlink): New function.
18289 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on

18316 do not dereference NULL upon failed strdup
18317 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
18318 (ns_get_family): Likewise.
18320 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
18322 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
18324 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
18326 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
18329 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
18331 Add lexical binding.

18340 Bind Qinternal_interpreter_environment.
18341 (Feval_buffer): Bind Qlexical_binding.
18342 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
18344 (syms_of_lread): Declare `lexical-binding'.
18346 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
18348 * keyboard.c (eval_dyn): New fun.
18349 (menu_item_eval_property): Use it.
18351 * image.c (parse_image_spec): Use Ffunctionp.
18353 * fns.c (concat, mapcar1): Accept byte-code-functions.
18355 * eval.c (Fsetq): Handle lexical vars.
18356 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
18357 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
18358 (FletX, Flet): Obey lexical binding.
18359 (Fcommandp): Handle closures.
18360 (Feval): New `lexical' arg.
18361 (eval_sub): New function extracted from Feval. Use it almost
18362 everywhere where Feval was used. Look up vars in lexical env.
18364 (Ffunctionp): Move from subr.el.
18365 (Ffuncall): Handle closures.
18366 (apply_lambda): Remove `eval_flags'.
18367 (funcall_lambda): Handle closures and new byte-code-functions.
18368 (Fspecial_variable_p): New function.
18369 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
18370 but without exporting it to Lisp.
18372 * doc.c (Fdocumentation, store_function_docstring):
18373 * data.c (Finteractive_form): Handle closures.
18375 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
18378 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
18380 (exec_byte_code): New function extracted from Fbyte_code to handle new
18381 calling convention for byte-code-functions. Add new byte-codes.
18383 * buffer.c (defvar_per_buffer): Set new `declared_special' field.

18389 * xdisp.c (redisplay_internal): Fix prototype.
18391 2011-03-31 Eli Zaretskii <eliz@gnu.org>
18393 * xdisp.c (SCROLL_LIMIT): New macro.
18394 (try_scrolling): Use it when setting scroll_limit.
18395 Limit scrolling to 100 screen lines.
18396 (redisplay_window): Even when falling back on "recentering",
18397 position point in the window according to scroll-conservatively,
18398 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
18400 (try_scrolling): When point is above the window, allow searching
18401 as far as scroll_max, or one screenful, to compute vertical
18402 distance from PT to the scroll margin position. This prevents
18403 try_scrolling from unnecessarily failing when
18404 scroll-conservatively is set to a value slightly larger than the
18405 window height. Clean up the case of PT below the margin at bottom
18406 of window: scroll_max can no longer be INT_MAX. When aggressive
18407 scrolling is in use, don't let point enter the opposite scroll
18408 margin as result of the scroll.
18409 (syms_of_xdisp) <scroll-conservatively>: Document the
18410 threshold of 100 lines for never-recentering scrolling.

18418 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
18419 (redisplay_internal): Remove parameter `preserve_echo_area',
18420 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
18422 * indent.c (Fvertical_motion):
18423 * window.c (window_scroll_pixel_based, Frecenter):
18424 Don't pass `need_y_p' to `move_it_by_lines'.
18426 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
18428 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
18429 steal a few bits to be more compact.
18430 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
18431 Remove unneeded casts.
18433 * bytecode.c (Fbyte_code): CAR and CDR can GC.
18435 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
18437 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
18438 binding" message (bug#7967).
18440 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
18442 Fix more problems found by GCC 4.6.0's static checks.
18444 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
18445 Remove unused local var.
18447 * editfns.c (Fmessage_box): Remove unused local var.
18449 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
18450 (note_mode_line_or_margin_highlight, note_mouse_highlight):
18451 Omit unused local vars.
18452 * window.c (shrink_windows): Omit unused local var.
18453 * menu.c (digest_single_submenu): Omit unused local var.
18454 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
18455 Omit unused local var.
18457 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
18458 Don't assume string length fits in int.
18459 (keyremap_step, read_key_sequence): Use size_t for sizes.

18462 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
18463 instead of alloca (Bug#8344).
18465 * eval.c (Fbacktrace): Don't assume nargs fits in int.
18466 (Fbacktrace_frame): Don't assume nframes fits in int.
18468 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

18475 * cm.c (calccost): Turn while-do into do-while, for clarity.
18477 * keyboard.c (syms_of_keyboard): Use the same style as later
18478 in this function when indexing through an array. This also
18479 works around GCC bug 48267.
18481 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
18483 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
18485 * chartab.c (sub_char_table_ref_and_range): Redo for slight
18486 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
18488 * keyboard.c, keyboard.h (num_input_events): Now size_t.
18489 This avoids undefined behavior on integer overflow, and is a bit
18490 more convenient anyway since it is compared to a size_t variable.
18492 Variadic C functions now count arguments with size_t, not int.
18493 This avoids an unnecessary limitation on 64-bit machines, which
18494 caused (substring ...) to crash on large vectors (Bug#8344).

18504 * fns.c (concat): Likewise.
18505 * frame.c (x_set_frame_parameters): Likewise.
18506 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
18507 0 if not found, not -1. All callers changed.
18509 * alloc.c (garbage_collect): Don't assume stack size fits in int.
18510 (stack_copy_size): Now size_t, not int.
18511 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

18532 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
18533 don't set the hook to nil, but remove the offending function instead.

18535 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
18536 Vcommand_hook_internal.
18538 * eval.c (enum run_hooks_condition): Remove.
18539 (funcall_nil, funcall_not): New functions.
18540 (run_hook_with_args): Call each function through a `funcall' argument.

18727 the first time through the loop, since we know p0 < p1 then.
18728 This also avoids a gcc -Wstrict-overflow warning.
18730 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
18731 leading to a memory leak, possible in functions like
18732 load_charset_map_from_file that can allocate an unbounded number
18733 of objects (Bug#8318).
18735 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
18736 that could (at least in theory) be that large.
18738 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
18739 This is less likely to overflow, and avoids undefined behavior if
18740 overflow does occur. All callers changed. Use strtoul to scan
18741 for the unsigned long integer.
18742 (pint2hrstr): Simplify and tune code slightly.
18743 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
18745 * scroll.c (do_scrolling): Work around GCC bug 48228.
18746 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

18751 This also avoids a warning with gcc -Wstrict-overflow.
18753 * fileio.c (Fcopy_file): Report error if fchown or fchmod
18756 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
18758 * process.c (Fmake_network_process): Use socklen_t, not int,
18759 where POSIX says socklen_t is required in portable programs.
18760 This fixes a porting bug on hosts like 64-bit HP-UX, where
18761 socklen_t is wider than int (Bug#8277).
18762 (Fmake_network_process, server_accept_connection):
18763 (wait_reading_process_output, read_process_output):
18766 * process.c: Rename or move locals to avoid shadowing.

18776 Make tparam.h and terminfo.c consistent.
18777 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
18778 Include tparam.h instead, since it declares them.
18779 * cm.h (PC): Remove extern decl; tparam.h now does this.
18780 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
18781 * terminfo.c: Include tparam.h, to check interfaces.
18782 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
18783 (tparam): Adjust signature to match interface in tparam.h;
18784 this removes some undefined behavior. Check that outstring and len
18785 are zero, which they always are with Emacs.
18786 * tparam.h (PC, BC, UP): New extern decls.
18788 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
18789 (xftfont_open): Rename locals to avoid shadowing.
18791 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

18803 * composite.c (composition_compute_stop_pos): Rename local to
18805 (composition_reseat_it): Remove unused locals.
18806 (find_automatic_composition, composition_adjust_point): Likewise.
18807 (composition_update_it): Mark var as initialized.
18808 (find_automatic_composition): Mark vars as initialized,
18809 with a FIXME (Bug#8290).

18813 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
18814 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
18815 (BUF_DEC_POS): Be more systematic about renaming local temporaries
18816 to avoid shadowing.
18818 * textprop.c (property_change_between_p): Remove; unused.
18820 * intervals.c (interval_start_pos): Now static.
18822 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

18827 * sound.c (wav_play, au_play, Fplay_sound_internal):
18828 Fix pointer signedness.
18829 (alsa_choose_format): Remove unused local var.
18830 (wav_play): Initialize a variable to 0, to prevent undefined
18831 behavior (Bug#8278).
18833 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
18835 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
18837 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
18838 clobbering (Bug#8298).
18839 * sysdep.c (sys_subshell): Likewise.
18840 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
18842 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
18843 This should get cleaned up, so that child_setup has the
18844 same signature on all platforms.
18846 * callproc.c (call_process_cleanup): Now static.
18847 (relocate_fd): Rename locals to avoid shadowing.
18849 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
18851 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
18852 not to be necessary, and produces flickering.
18854 2011-03-20 Glenn Morris <rgm@gnu.org>
18856 * config.in: Remove file.
18858 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
18860 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
18861 are now in src/globals.h.
18862 (syms_of_minibuf): Remove spurious & from previous change.
18864 2011-03-20 Leo Liu <sdl.web@gmail.com>
18866 * minibuf.c (completing-read-function): New variable.

18872 * xfaces.c (Fx_load_color_file):
18873 Read color file from absolute filename (bug#8250).
18875 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
18877 * makefile.w32-in: Update dependencies.
18879 2011-03-17 Eli Zaretskii <eliz@gnu.org>
18881 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

18888 (sigchld_handler): Now static.
18890 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
18891 That way, the code declares only the vars that it needs.

18902 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
18903 Define only if needed.
18905 * unexelf.c (unexec): Name an expression,
18906 to avoid gcc -Wbad-function-cast warning.
18907 Use a different way to cause a compilation error if anyone uses
18908 n rather than nn, a way that does not involve shadowing.
18909 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
18911 * deps.mk (unexalpha.o): Remove; unused.
18913 New file unexec.h, the (simple) interface for unexec (Bug#8267).
18914 * unexec.h: New file.
18915 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
18916 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
18917 Depend on unexec.h.
18918 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
18919 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
18920 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.

18976 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
18977 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
18978 some of which prompt warnings from gcc -Wbad-function-cast.
18979 (Fformat_time_string, Fencode_time, Finsert_char):
18980 (Ftranslate_region_internal, Fformat):
18981 Rename or remove local vars to avoid shadowing.

18984 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
18987 * lisp.h (eassert): Check that the argument compiles, even if
18988 ENABLE_CHECKING is not defined.
18990 * data.c (Findirect_variable): Name an expression, to avoid
18991 gcc -Wbad-function-cast warning.

19003 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
19004 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
19006 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
19007 (GC_STRING_CHARS): Remove; not used.
19008 (Fmemory_limit): Cast sbrk's returned value to char *.
19010 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
19011 avoids undefined behavior in theory.
19013 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
19015 Use functions, not macros, for up- and down-casing (Bug#8254).
19016 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
19017 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
19018 to use the following functions instead of these macros.
19019 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
19020 EMACS_INT, since callers assume the returned value fits in int.
19021 (upcase1): Likewise, for UPCASE_TABLE.
19022 (uppercasep, lowercasep, upcase): New static inline functions.
19023 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

19032 which gcc can warn about.
19033 (regex_compile, re_match_2_internal): Mark locals as initialized.
19034 (RETALLOC_IF): Define only if needed.
19035 (WORDCHAR_P): Likewise. This one is never needed, but is used
19036 only in a comment talking about a compiler bug, so put inside
19037 the #if 0 of that comment.
19038 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
19039 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
19042 * search.c (boyer_moore): Rename locals to avoid shadowing.

19065 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
19066 New macros, so that the caller can use some names other than
19067 gcpro1, gcpro2, etc.
19068 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
19070 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
19071 argument, for consistency with GCPRO2_VAR, etc: it is now the
19072 prefix of the variable, not the variable itself. All uses
19074 * dired.c (directory_files_internal, file_name_completion):
19075 Rename locals to avoid shadowing.
19077 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
19078 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
19079 dired.c's scmp function, had undefined behavior.
19080 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
19081 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
19082 * buffer.h: ... to here, because these macros use current_buffer,
19083 and the new implementation with inline functions needs to have
19084 current_buffer in scope now, rather than later when the macros
19086 (downcase, upcase1): New static inline functions.
19087 (DOWNCASE, UPCASE1): Reimplement using these functions.
19088 This avoids undefined behavior in expressions like
19089 DOWNCASE (x) == DOWNCASE (y), which previously suffered
19090 from race conditions in accessing the global variables
19091 case_temp1 and case_temp2.
19092 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
19093 * lisp.h (case_temp1, case_temp2): Remove their decls.
19094 * character.h (ASCII_CHAR_P): Move from here ...
19095 * lisp.h: ... to here, so that the inline functions mentioned
19096 above can use them.
19098 * dired.c (directory_files_internal_unwind): Now static.
19100 * fileio.c (file_name_as_directory, directory_file_name):
19101 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
19103 (file_name_as_directory): Use const pointers when appropriate.
19104 (Fexpand_file_name): Likewise. In particular, newdir might
19105 point at constant storage, so make it a const pointer.
19106 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
19107 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
19109 (Fset_file_times, Finsert_file_contents, auto_save_error):

19114 to avoid shadowing.
19116 * marker.c (bytepos_to_charpos): Remove; unused.
19118 * lisp.h (verify_bytepos, count_markers): New decls,
19119 so that gcc does not warn that these functions aren't declared.
19121 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
19122 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
19123 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
19124 (copy_text): Remove unused local var.
19126 * filelock.c (within_one_second): Now static.
19127 (lock_file_1): Rename local to avoid shadowing.
19129 * buffer.c (fix_overlays_before): Mark locals as initialized.
19130 (fix_start_end_in_overlays): Likewise. This function should be
19131 simplified by using pointers-to-pointers, but that's a different
19133 (switch_to_buffer_1): Now static.
19134 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
19135 (report_overlay_modification): Rename locals to avoid shadowing.
19137 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
19138 Fix pointer signedness issue.
19139 (sys_subshell): Mark local as volatile if checking for lint,
19140 to suppress a gcc -Wclobbered warning that does not seem to be right.
19141 (MAXPATHLEN): Define only if needed.
19143 * process.c (serial_open, serial_configure): Move decls from here ...
19144 * systty.h: ... to here, so that they can be checked.
19146 * fns.c (get_random, seed_random): Move extern decls from here ...
19147 * lisp.h: ... to here, so that they can be checked.
19149 * sysdep.c (reset_io): Now static.
19150 (wait_for_termination_signal): Remove; unused.
19152 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

19155 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
19156 (DENSE_TABLE_SIZE): Remove; unused.
19157 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
19158 (describe_map_tree):
19159 Rename locals to avoid shadowing.
19161 * keyboard.c: Declare functions static if they are not used elsewhere.

19167 (parse_tool_bar_item, read_key_sequence, Fread_key_sequence):
19168 (Fread_key_sequence_vector): Rename locals to avoid shadowing.
19169 (read_key_sequence, read_char): Mark locals as initialized.
