3 * indent.c (Fvertical_motion): If a display string will be
4 displayed on the left or the right margin, don't consider it as a
5 factor in cursor positioning. (Bug#13108)
7 2012-12-07 Martin Rudalics <rudalics@gmx.at>
9 * editfns.c (Fcompare_buffer_substrings): Reword doc-string.
11 2012-12-05 Eli Zaretskii <eliz@gnu.org>
13 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
14 fails, signal an error instead of continuing with an empty
16 Encode expanded temp file pattern before passing it to mkstemp or
19 2012-12-04 Eli Zaretskii <eliz@gnu.org>
21 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
22 Encode the file name before passing it to dostounix_filename, in
23 case it will downcase it (under w32-downcase-file-names).
26 2012-12-01 Chong Yidong <cyd@gnu.org>
28 * fileio.c (Vauto_save_list_file_name): Doc fix.
30 2012-11-30 Fabrice Popineau <fabrice.popineau@gmail.com>
32 * w32fns.c: Remove prototype of atof.
33 (syspage_mask): Declared DWORD_PTR, for compatibility with 64-bit
35 (file_dialog_callback): Declared UINT_PTR.
37 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
40 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
41 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
44 2012-11-27 Glenn Morris <rgm@gnu.org>
46 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
48 2012-11-26 Eli Zaretskii <eliz@gnu.org>
50 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
53 2012-11-24 Paul Eggert <eggert@cs.ucla.edu>
55 Revert recent change for Bug#8855.
56 As reported by Harald Hanche-Olsen in
57 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00445.html>
58 the change introduces a further bug, of creating lots of zombie
59 processes in some cases. Further work is needed to come up with a
60 better fix for Bug#8855.
62 2012-11-24 Eli Zaretskii <eliz@gnu.org>
64 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
65 highlighting on the frame was cleared. Prevents assertion
66 violations when repeatedly clicking on the "Top" link of the
67 "bread-crumbs" in Info buffers.
69 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>

72 Fix a race condition with glib (Bug#8855).
73 The symptom is a diagnostic "GLib-WARNING **: In call to
74 g_spawn_sync(), exit status of a child process was requested but
75 SIGCHLD action was set to SIG_IGN and ECHILD was received by
76 waitpid(), so exit status can't be returned." The diagnostic
77 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
78 The real bug is a race condition between Emacs and glib: Emacs
79 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
80 so that glib can't find it. Work around the bug by invoking
81 waitpid only on subprocesses that Emacs itself creates.
83 This is a backport from the trunk, consisting of:
85 * w32proc.c (create_child): Don't clip the PID of the child
86 process to fit into an Emacs integer, as this is no longer a
88 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
89 reaping only the process specified by PID argument, if that is
90 positive. Use PID instead of dead_child to know which process to
91 reap. Wait for the child to die only if WNOHANG is not in
93 (sys_select): Don't set dead_child.
95 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
96 as it is no longer needed.
98 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
100 (create_process, record_child_status_change): Don't use special
101 value -1 in pid field, as the caller now must know the pid rather
102 than having the callee infer it. The inference was sometimes
103 incorrect anyway, due to another race.
104 (create_process): Set new 'alive' member if child is created.
105 (process_status_retrieved): New function.
106 (record_child_status_change): Use it.
107 Accept negative 1st argument, which means to wait for the
108 processes that Emacs already knows about. Move special-case code
109 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
110 processes that have already been waited for, by testing and
111 clearing new 'alive' member. Remove the setting of
112 record_at_most_one_child for the !WNOHANG case.
113 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
114 now does this internally.
115 (handle_child_signal): Let record_child_status_change do all
116 the work, since we do not want to reap all exited child processes,
117 only the child processes that Emacs itself created.
118 * process.h (Lisp_Process): New boolean member 'alive'.
120 2012-11-23 Eli Zaretskii <eliz@gnu.org>
122 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
123 between bpos_covered and bpos_max. This fixes cursor display when
124 several display strings follow each other.
126 * .gdbinit (pgx): If the glyph's object is a string, display the
127 pointer to string data, rather than the value of the string object
128 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
130 2012-11-21 Eli Zaretskii <eliz@gnu.org>
132 * indent.c (Fvertical_motion): If the starting position is covered
133 by a display string, return to one position before that, to avoid
134 overshooting it inside move_it_to. (Bug#12930)
136 2012-11-20 Daniel Colascione <dancol@dancol.org>
138 * w32fns.c (Fx_file_dialog):
139 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
140 cygwin_convert_file_name*.
142 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
143 Rename cygwin_convert_path* to cygwin_convert_file_name*.
145 2012-11-20 Ken Brown <kbrown@cornell.edu>
147 * emacs.c (main): Set the G_SLICE environment variable for all
148 Cygwin builds, not just GTK builds. See
149 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
151 2012-11-19 Eli Zaretskii <eliz@gnu.org>
153 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Don't mix declaration of
154 w32_note_current_window with code. (Backport from trunk.)
156 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
157 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
158 Define for the MSVC compiler.
160 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing
163 2012-11-18 Eli Zaretskii <eliz@gnu.org>
165 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
166 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
167 dostounix_filename. Prevents crashes down the road, because
168 dostounix_filename assumes it gets a unibyte string. Reported by
169 Michel de Ruiter <michel@sentient.nl>, see
170 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
172 2012-11-17 Eli Zaretskii <eliz@gnu.org>
174 * w32select.c: Include w32common.h before w32term.h, so that
175 windows.h gets included before w32term.h uses some of its
178 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]: New
180 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]: New
182 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
184 2012-11-17 Jan Djärv <jan.h.d@swipnet.se>
186 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
187 (ns_select): Return at once if events are held (Bug#12834).
189 2012-11-16 enami tsugutomo <tsugutomo.enami@jp.sony.com>
191 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
192 Needed following 2012-10-20 change. (Bug#12902)
194 2012-11-16 Glenn Morris <rgm@gnu.org>
196 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
198 2012-11-15 Stefan Monnier <monnier@iro.umontreal.ca>
200 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
202 2012-11-14 Eli Zaretskii <eliz@gnu.org>
204 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
205 use the same value of thread handle.
206 (start_timer_thread): If the timer thread exited (due to error),
207 clean up by closing the two handles it used. Duplicate the caller
208 thread's handle here, so it gets duplicated only once, when
209 launching the timer thread. Set priority of the timer thread, not
211 (getitimer): Don't duplicate the caller thread's handle here.
214 2012-11-13 Jan Djärv <jan.h.d@swipnet.se>
216 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
219 2012-11-12 Eli Zaretskii <eliz@gnu.org>
221 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
222 passed to pint2str and pint2hrstr to be at most the size of the
223 frame's decode_mode_spec_buffer. This avoids crashes with very
224 large values of FIELD_WIDTH argument to decode_mode_spec.
227 2012-11-07 Martin Rudalics <rudalics@gmx.at>
229 * window.c (Fsplit_window_internal): Set combination limit of
230 new parent window to t iff Vwindow_combination_limit is t;
231 fixing a regression introduced with the change from 2012-09-22.
232 (Fwindow_combination_limit, Fset_window_combination_limit):
235 2012-11-06 Eli Zaretskii <eliz@gnu.org>
237 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
238 amount when the scroll margins are too large. When scrolling
239 backwards in the buffer, give up if cannot reach point or the
240 scroll margin within a reasonable number of screen lines.
241 Fixes point position in window under scroll-up/down-aggressively when
242 point is positioned many lines beyond the window top/bottom.
245 2012-11-05 Eli Zaretskii <eliz@gnu.org>
247 * ralloc.c (relinquish): If real_morecore fails to return memory
248 to the system, don't crash; instead, leave the last heap
249 unchanged and return. (Bug#12774)
251 2012-11-03 Eli Zaretskii <eliz@gnu.org>
253 * lisp.mk: Adjust comments to the fact that term/internal is now
254 loaded from loadup.el.
256 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
257 (msdos_fatal_signal): New function.
258 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
261 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
262 for GCC versions before 4.
263 (emacs_raise): Define to call msdos_fatal_signal.
265 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
266 iterator when starting in the middle of a display or overlay
269 2012-11-03 Jan Djärv <jan.h.d@swipnet.se>
271 * widget.c (resize_cb): New function.
272 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
273 (EmacsFrameResize): Check if all is up to date before changing frame
276 2012-11-01 Eli Zaretskii <eliz@gnu.org>
278 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
280 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
282 Fix crash when using Emacs as commit editor for git (Bug#12697).
283 * callproc.c (setpgrp): Remove macro, as we now use setpgid
284 and it is configured in conf_post.h.
285 (Fcall_process): Don't invoke both setsid and setpgid; the former
286 is enough, if it exists.
287 * callproc.c (Fcall_process, child_setup):
288 * process.c (create_process): Use setpgid.
289 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
291 * dispnew.c (init_display): Initialize the foreground group
292 if we are running a tty display.
293 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
294 * lisp.h (init_foreground_group): New decl.
295 * sysdep.c (inherited_pgroup): New static var.
296 (init_foreground_group, tcsetpgrp_without_stopping)
297 (narrow_foreground_group, widen_foreground_group): New functions.
298 (init_sys_modes): Narrow foreground group.
299 (reset_sys_modes): Widen foreground group.
301 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
303 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
305 2012-10-31 Martin Rudalics <rudalics@gmx.at>
307 * minibuf.c (read_minibuf): Restore current buffer since
308 choose_minibuf_frame calling Fset_frame_selected_window may
309 change it (Bug#12766).
311 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
313 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
315 2012-10-30 Kenichi Handa <handa@gnu.org>
317 * font.c (Ffont_at): If WINDOW is specified and it is not
318 displaying the current buffer, signal an error.
320 2012-10-29 Daniel Colascione <dancol@dancol.org>
322 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
323 In preparation for fixing bug#12739, move these functions from
326 * coding.h, coding.c: ... to here, and compile them only when
327 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
328 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
330 2012-10-28 Eli Zaretskii <eliz@gnu.org>
332 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
333 (timer_loop, getitimer, setitimer): Use it instead of
334 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
336 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
339 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
341 * nsterm.m (NO_APPDEFINED_DATA): New define.
342 (last_appdefined_event_data): New variable
343 (last_appdefined_event): Remove.
344 (ns_select): Initialize t from last_appdefined_event_data instead
345 of [last_appdefined_event data1].
346 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
347 remove last_appdefined_event (Bug#12698).
349 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
351 * frame.c (x_set_font): Catch internal error.
353 2012-10-27 Eli Zaretskii <eliz@gnu.org>
355 Avoid overflow in w32 implementation of interval timers.
356 When possible, for ITIMER_PROF count only times the main thread
358 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
359 'volatile ULONGLONG' types. All the other data which was
360 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
361 (GetThreadTimes_Proc): New typedef.
362 (w32_get_timer_time): New function, returns a suitable time value
364 (timer_loop): Enter critical section when accessing ULONGLONG
365 values of the itimer_data struct, as these accesses are no longer
366 atomic. Call 'w32_get_timer_time' instead of 'clock'.
367 Remove unused variable.
368 (init_timers): Initialize s_pfn_Get_Thread_Times.
369 (start_timer_thread): Don't assign itimer->caller_thread here.
370 (getitimer): Assign itimer->caller_thread here.
371 (setitimer): Always call getitimer to get the value of ticks_now.
372 (sys_spawnve): Avoid compiler warning about format mismatch.
374 2012-10-26 Eli Zaretskii <eliz@gnu.org>
376 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
377 mouse movement events if the menu bar is active. This avoids
378 producing a busy "hour-glass" cursor by Windows if the mouse
379 pointer is positioned over a tooltip shown for some menu item.
381 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
383 Don't assume process IDs fit in int.
384 * emacs.c (shut_down_emacs) [!DOS_NT]:
385 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
386 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
387 Use pid_t, not int, to store process IDs, as 'int'
388 is not wide enough on a few platforms (e.g., AIX and IRIX).
390 2012-10-23 Kenichi Handa <handa@gnu.org>
392 The following change is to make face-font-rescale-alist work
393 correctly for non-ASCII fonts.
395 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
396 (font_open_for_lface): Handle Vface_font_rescale_alist.
398 2012-10-23 Chong Yidong <cyd@gnu.org>
400 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
402 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
404 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
406 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
408 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
411 2012-10-21 Glenn Morris <rgm@gnu.org>
413 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
415 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
418 * frame.c (Fmouse_position, Fmouse_pixel_position):
419 * xdisp.c (produce_stretch_glyph):
420 Declare local vars only when they're needed.
421 This is clearer and avoids a warning on OpenBSD about unused vars.
422 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
423 This is safer, and avoids OpenBSD warnings about unused vars.
424 * keyboard.c (record_menu_key): Remove unnecessary decl.
425 (poll_timer): Define only if POLL_FOR_INPUT is defined.
426 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
427 as our definition clashes with OpenBSD's.
428 * xfaces.c (load_face_colors, check_lface_attrs)
429 (get_lface_attributes_no_remap, get_lface_attributes)
430 (lface_fully_specified_p, x_supports_face_attributes_p)
431 (tty_supports_face_attributes_p, face_fontset, realize_face)
432 (realize_x_face, realize_tty_face):
433 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
434 merely Lisp_Object *. This is more informative and avoids
435 a warning on OpenBSD about accessing beyond an object's size.
437 2012-10-20 Chong Yidong <cyd@gnu.org>
439 * lread.c (Fload): Doc fix (Bug#12592).
441 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
443 * font.c (Ffont_at): Fix previous change.
445 2012-10-19 Eli Zaretskii <eliz@gnu.org>
447 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
448 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
451 * alloc.c (NSTATICS): Decrease to 0x800.
453 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>
455 * fns.c (Fnreverse): Include the problem element when signalling an
458 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
460 * nsterm.m (ns_select): Check writefds before call to
461 FD_ISSET (Bug#12668).
463 2012-10-18 Daniel Colascione <dancol@dancol.org>
465 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
466 (staticpro): If we run out of staticpro slots, die with an
467 informative error instead of just calling emacs_abort.
469 2012-10-18 Martin Rudalics <rudalics@gmx.at>
471 Fix two flaws reported by Dmitry Antipov.
472 * window.c (Ftemp_output_buffer_show): Remove.
473 (Fwindow_vscroll, Fset_window_vscroll): Use decode_live_window.
474 (syms_of_window): Remove defsubr for Stemp_output_buffer_show.
476 2012-10-17 Eli Zaretskii <eliz@gnu.org>
478 * makefile.w32-in ($(BLD)/w32.$(O)):
479 ($(BLD)/vm-limit.$(O)):
481 ($(BLD)/unexw32.$(O)):
482 ($(BLD)/fileio.$(O)):
483 ($(BLD)/dispnew.$(O)): Update dependencies.
485 * w32term.h (w32_initialize_display_info, initialize_w32_display):
488 * w32proc.c: Include ctype.h.
490 * w32.h (init_environment, check_windows_init_file)
491 (syms_of_ntproc, syms_of_ntterm, dostounix_filename)
492 (unixtodos_filename, init_winsock, srandom, random, sys_pipe)
493 (set_process_dir, sys_spawnve, register_child, sys_sleep, getwd)
494 (sys_link): Add prototypes.
496 * w32.c: Include w32select.h.
497 (sys_access, e_malloc, sys_select): Add prototypes.
498 (emacs_gnutls_pull): 'timeout' is now EMACS_TIME, not struct timeval.
500 * vm-limit.c [WINDOWSNT]: Include w32heap.h.
502 * unexw32.c: Include lisp.h and w32.h.
504 * term.c [WINDOWSNT]: Include w32term.h.
506 * process.c [WINDOWSNT]: Add prototype of sys_select.
508 * fileio.c [WINDOWSNT]: Include w32.h.
510 * dispnew.c [WINDOWSNT]: Include w32.h.
512 * cygw32.c (Fcygwin_convert_path_to_windows)
513 (Fcygwin_convert_path_from_windows): Use EQ to compare 2
514 Lisp_Object values. (Bug#12661)
516 * w32fns.c (w32_msg_pump): Use XIL instead of casting an integer
517 to Lisp_Object. (Bug#12661)
519 2012-10-17 Kenichi Handa <handa@gnu.org>

722 * keyboard.c (timers_run, swallow_events)
723 (detect_input_pending_run_timers):
724 * process.c (wait_reading_process_output):
725 Use unsigned for counter where wraparound-on-overflow is desired,
726 since unsigned is guaranteed to have that behavior and signed is not.
727 (read_char): Use ptrdiff_t for string length.
728 (get_input_pending): Remove first argument, since it was always
729 the same pointer-to-int (now pointer-to-boolean) &input_pending,
730 and behave as if it had that value. Return new value of
731 input_pending. All callers changed.
732 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
733 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's

754 * termopts.h (flow_control, meta_key): Remove unused decls.
755 * dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c:
756 Don't include termopts.h.
758 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>

773 2012-10-09 Eli Zaretskii <eliz@gnu.org>
775 * w32fns.c (w32_last_error): Change the return value to DWORD, to
776 match what GetLastError returns. Explain why the function is
779 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
780 'is_tooltip_frame', to avoid confusion with its global namesake.
782 2012-10-08 Daniel Colascione <dancol@dancol.org>
784 * xdisp.c (start_hourglass): Call w32_note_current_window when
785 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
786 build that caused Emacs to display the hourglass cursor forever.
788 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
789 which is broken under remote desktop, calculate the number of
790 colors available for a display based on the display's number of
791 planes and number of bits per pixel per plane. (bug#10397).
793 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
795 * nsfont.m (Vfonts_in_cache): New variable.
796 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
797 are used. Add cached fonts to Vfonts_in_cache.
798 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
800 2012-10-08 Juanma Barranquero <lekktu@gmail.com>

804 (FONT_H): Define after FRAME_H.
805 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
808 * w32term.c: Remove leftover declaration of keyboard_codepage.

813 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
814 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
815 (GLOBAL_SOURCES): Add cygw32.c.
816 ($(BLD)/unexw32.$(O)):
818 ($(BLD)/w32console.$(O)):

824 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
826 (x_to_w32_color): Don't modify the argument, modify a copy instead.
828 2012-10-08 Daniel Colascione <dancol@dancol.org>
830 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
831 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
832 accidental message numbering hole. Change other messages to

848 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
849 (w32_minor_version, w32_build_number, w32_subtype):
850 Remove duplicate definitions.
852 * w32fns.c: Include w32common.h; include w32heap.h only in
855 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
856 Use `report_file_error' instead of `error' in order to better
857 inform users of what went wrong. Increase NTGUI_UNICODE file
858 dialog box file name length to 32k, the maximum allowed by the NT
861 * w32common.h: New file.
862 (ROUND_UP, ROUND_DOWN, get_page_size)
863 (get_allocation_unit, get_processor_type, get_w32_major_version)
864 (get_w32_minor_version, sysinfo_cache, osinfo_cache)

866 (OS_NT, os_subtype, cache_system_info): Move here.
868 * unexw32.c, unexcw.c: Include w32common.h.
870 * emacs.c (main): Use (defined (WINDOWSNT) || defined

872 to call syms_of_w32select.
874 * cygw32.h: Remove obsolete EXFUN declarations.
876 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
878 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
879 of w32inevt.o from SOME_MACHINE_OBJECTS.
881 2012-10-08 Daniel Colascione <dancol@dancol.org>
883 * image.c: Permanent fix for JPEG compilation issue --- limit
884 jpeglib `boolean' redefinition to Cygwin builds.
886 2012-10-08 Eli Zaretskii <eliz@gnu.org>
888 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
890 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
893 2012-10-08 Daniel Colascione <dancol@dancol.org>
895 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
896 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,

899 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
900 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
901 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
902 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
903 now a supported configuration.
905 * Makefile.in: consolidate image variables into LIBIMAGE; add
906 W32_OBJ and W32_LIBS. Compile new files.
909 (_DebPrint) declare tracing facility for W32 debugging. We need
910 to unify tracing later.
912 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
913 unconditional use of W32 Unicode functions. Cygwin runs only on
914 100% Unicode operating systems.
916 * cygw32.c: New file. Define Cygwin-specific facilities.
917 (Fcygwin_convert_path_to_windows)
918 (Fcygwin_convert_path_from_windows): New user functions for
919 accessing Cygwin path-munging routines.
921 * cygw32.h: New file.
922 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
923 UTF-16LE strings temporarily inside non-Lisp-visible string
926 (w32_strerror): Just what it says on the tin.
928 * emacs.c: Make the NS fork-then-exec code for daemon-launching
929 also run for Cygwin; both systems have the same problem with using
930 GUI facilities in a forked child. Also call syms_of_cygw32,
931 syms_of_w32select in correct places.
933 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
934 needs fork-then-exec for daemon launching.
936 * font.h: Include frame.h.
938 * image.c: Use the image library cache machinery only when we're
939 compiling for native WINDOWSNT; Cygwin can use shared libraries
940 like any other Unixlike system.
942 * keyboard.c: Clarify a comment regarding the input loop.
944 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
945 functions directly instead of trying to detect at runtime that our
946 host operating system supports them. We make this change for two
947 reasons: Cygwin lacks support for the multibyte character
948 conversion functions used by the legacy menu code, and Cygwin
949 never needs to rely on non-Unicode APIs.
951 * unexw32.c (hinst): Declare extern.
953 * w32.c: Change header order;
954 (w32_strerror): Move to w32fns.c because we need it for
955 non-WINDOWSNT builds.
957 * w32.h: Add #error macro to make sure we don't include w32.h for
958 Cygwin builds. Remove w32select declarations.
960 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
961 w32fns.c. w32console.c is WINDOWSNT-only.
963 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
964 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
966 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
967 (w32_major_version, w32_minor_version, w32_build_number)
968 (os_subtype, sound_type): Define here
969 (w32_defined_color): Make color parameter const for consistency
970 with other _defined_color functions.
971 (w32_createwindow): Unconditionally call w32_init_class instead of
972 doing so only when hprevinst is non-NULL. Plumbing hprevinst
973 through the code is complex and unnecessary because class
974 registration is practically free.
975 (w32_name_of_message): New EMACSDEBUG-only function.
976 (Fset_message_beep): Move here
977 (Fx_open_connection): Require that the display name for Windows be
978 "w32" for consistency, emacsclient disambiguation, and maybe, one
979 day, multi-window-system support.
980 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
981 Cygwin files for W32 GUI facilities, since these clearly don't
984 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
985 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
986 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
987 (w32_last_error): Remove.
989 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
991 * w32heap.c (syspage_mask): Declare here.
992 (cache_system_info): Remove.
994 * w32inevt.c (faked_key): Define globally, not statically.
995 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
996 (w32_console_toggle_lock_key): Move to w32fns.c.
998 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
1000 * w32proc.c (_DebPrint): Move to w32fns.c.
1001 * w32select.c: Include string.h, stdio.h for Cygwin.
1002 * w32select.h: New File.
1004 * w32term.c: Include io.h for non-CYGWIN builds; needed for
1006 (w32_message_fd): New variable. Under Cygwin, holds the file
1007 descriptor the system used to tell us about pending thread
1010 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
1011 that prevented compilation under non-WINDOWSNT systems.
1013 (w32_initialize): Open /dev/windows and assign it to
1014 w32_message_fd. Provide w32 feature.
1016 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
1017 (WM_EMACS_INPUT_READY): add.
1018 (prepend_msg, w32_message_fd): Declare globally.
1021 (keyboard_handle): Use only when WINDOWSNT.
1022 (notify_msg_ready): New function. Posts a message to the main
1023 thread's message queue under CYGWIN, which wakes up the main
1024 thread from select(2) by making the /dev/windows file descriptor
1025 ready. Under WINDOWSNT, it sets an event the same way the old
1028 (post, prepend_msg): Actually call notify_msg_ready instead of
1029 setting the input event directly.
1031 2012-10-07 Eli Zaretskii <eliz@gnu.org>
1033 * ralloc.c (relinquish): If a heap is ready to be relinquished,
1034 but it still has blocs in it, don't return it to the system,
1035 instead of aborting. (Bug#12402)
1037 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
1039 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).

1070 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
1072 Improve sys_siglist detection.
1073 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
1074 defined as a macro, as is done in Solaris.
1075 (sys_siglist_entries): New macro.
1076 (save_strsignal): Use it.
1077 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
1078 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
1080 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
1082 * nsfns.m (Fx_create_frame): Call x_default_parameter with
1083 fullscreen/Fullscreen.
1085 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
1086 tobar_height is new.
1088 * nsterm.m (x_make_frame_visible): Check for fullscreen.
1089 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
1090 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.

1099 (canBecomeMainWindow): New function.
1101 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
1103 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
1105 2012-10-05 Eli Zaretskii <eliz@gnu.org>
1107 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
1109 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
1110 that time stamps of directories could also be changed.
1111 Don't request the too broad GENERIC_WRITE, only the more restrictive
1112 FILE_WRITE_ATTRIBUTES access rights.
1114 * fileio.c (Fset_file_times): Special-case ignoring errors for
1115 directories only on MSDOS, not on MS-Windows.
1117 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
1119 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
1121 2012-10-04 Eli Zaretskii <eliz@gnu.org>
1123 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
1124 see whether CreateFile failed.
1126 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
1128 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
1129 to avoid similar races.
1130 * keyboard.c (pending_signals): Now bool, not int.
1132 Port timers to OpenBSD, plus check for timer failures.
1133 OpenBSD problem reported by Han Boetes.
1134 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
1136 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
1137 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
1138 like OpenBSD, which has timer_settime but does not declare it.
1139 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
1140 whether to use itimerspec-related primitives. All uses of
1141 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
1143 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
1145 * profiler.c (handle_profiler_signal): Fix a malloc race
1146 that caused Emacs to hang on Fedora 17 when profiling Lisp.
1148 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
1150 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
1152 2012-10-02 Eli Zaretskii <eliz@gnu.org>
1154 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
1155 consistent with the change in return value of 'safe_strsignal'.
1157 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
1159 Prefer plain 'static' to 'static inline' (Bug#12541).
1160 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
1161 (bidi_set_sor_type, bidi_push_embedding_level)
1162 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

1167 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
1168 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
1169 Now 'static', not 'static inline'.
1171 Count overruns when profiling; change units to ns.
1172 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
1173 Give extra weight to samples after overruns, to attempt to count
1174 the time more accurately.
1175 (setup_cpu_timer): Change sampling interval units from ms to ns, since
1176 the underlying primitives nominally do ns.
1177 (Fprofiler_cpu_start): Document the change. Mention that
1178 the sampling intervals are only approximate.
1180 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
1182 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
1184 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
1185 case for the special 0 coding-system.
1187 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
1188 (Fmake_overlay): Remove redundant tests.
1189 (fix_start_end_in_overlays): Remove redundant recentering.
1191 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
1193 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
1194 Update dependencies.
1196 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
1198 Fix a malloc race condition involving strsignal.
1199 A signal can arrive in the middle of a malloc, and Emacs's signal
1200 handler can invoke strsignal, which can invoke malloc, which is
1201 not portable. This race condition bug makes Emacs hang on GNU/Linux.
1202 Fix it by altering the signal handler so that it does not invoke
1204 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
1205 * process.c (status_message): Use const pointer, in case strsignal
1206 is #defined to safe_strsignal.
1207 * sysdep.c (sys_siglist, init_signals): Always define and
1208 initialize a substitute sys_siglist if the system does not define
1209 one, even if HAVE_STRSIGNAL.
1210 (safe_strsignal): Rename from strsignal. Always define,
1211 using sys_siglist. Return a const pointer.
1212 * syssignal.h (safe_strsignal): New decl.
1213 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
1215 2012-10-01 Eli Zaretskii <eliz@gnu.org>
1217 * w32proc.c (timer_loop): Fix code that waits for timer
1218 expiration, to avoid high CPU usage.
1220 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
1222 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
1223 (sweep_weak_table): Remove redundant prototypes.
1225 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
1227 * emacs.c: Move the inclusion of TERM_HEADER after including
1228 windows.h on WINDOWSNT. This avoids compilation problems with
1231 2012-10-01 Eli Zaretskii <eliz@gnu.org>
1233 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
1234 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
1235 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
1236 as the previous version used 'void *'.
1238 * ralloc.c (ROUNDUP): Fix last change.
1239 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
1242 * w32proc.c <disable_itimers>: New static flag.
1243 (init_timers): Initialize it to zero, after creating the critical
1244 sections used by the timer threads.
1245 (term_timers): Set to 1 before deleting the critical sections.
1246 (getitimer, setitimer): If disable_itimers is non-zero, return an
1247 error indication without doing anything. Reported by Fabrice
1248 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
1249 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
1251 [!HAVE_SETITIMER]: Behave as the previous version that didn't
1254 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
1255 term_ntproc after all the other bookkeeping, to get timers working
1256 as long as possible.
1258 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
1260 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
1261 Suggested by Juri Linkov in
1262 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
1264 Prefer plain 'static' to 'static inline' (Bug#12541).
1265 With static functions, modern compilers inline pretty well by
1266 themselves; advice from programmers often hurts as much as it helps.
1267 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
1268 this change shrinks the text size of the Emacs executable by 1.1%
1269 without affecting CPU significantly in my benchmark.
1270 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

1345 (x_set_glyph_string_clipping, x_clear_glyph_string_rect):
1346 Now 'static', not 'static inline'.
1349 (bidi_copy_it): Do the whole copy with a single memcpy.
1350 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
1352 Revert the FOLLOW-SYMLINKS change for file-attributes.
1353 Doing it right would require several changes to Tramp, and there's
1354 not enough time to get that tested before the freeze today.
1355 * dired.c (directory_files_internal, Ffile_attributes):
1358 * frame.c (x_report_frame_params): Port better to wider ints.
1359 Do not assume that EMACS_UINT is the same width as uprintmax_t,
1360 or that pointers can be printed in 15 decimal digits.
1361 Avoid GCC warnings if EMACS_UINT is wider than a pointer.
1363 2012-09-30 Fabrice Popineau <fabrice.popineau@supelec.fr>

1395 compatibility with x64.
1397 * vm-limit.c (lim_data): Now size_t.
1398 (check_memory_limits): Adjust prototypes of real_morecore and
1399 __morecore to receive argument of type ptrdiff_t. Use size_t for

1402 * unexw32.c: Use DWORD_PTR instead of DWORD for file-scope
1403 variables, for compatibility with x64.

1542 Suggested by Eli Zaretskii in
1543 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
1545 2012-09-30 Eli Zaretskii <eliz@gnu.org>
1547 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
1548 HAVE_TIMER_SETTIME is defined.
1550 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
1552 Profiler improvements: more-accurate timers, overflow checks.
1553 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
1554 signal.h, setjmp.h. Include systime.h instead.
1555 (saturated_add): New function.
1556 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.
1557 (record_backtrace, handle_profiler_signal): Saturate on fixnum overflow.

1560 (enum profiler_cpu_running): New enum.
1561 (profiler_cpu_running): Now of that enum type, not bool.
1562 All uses changed to store the new value.
1563 (handle_profiler_signal): Rename from sigprof_handler_1,
1564 for consistency with other handlers. Do not check whether
1565 cpu_log is a hash-table if garbage collecting, since it
1566 doesn't matter in that case.

1568 for consistency with other handlers.
1569 (setup_cpu_timer): New function, with much of what used to be in
1570 Fprofiler_cpu_start. Check for out-of-range argument.
1571 Prefer timer_settime if available, and prefer
1572 thread cputime clocks, then process cputime clocks, then
1573 monotonic clocks, to the old realtime clock. Use make_timeval
1574 to round more-correctly when falling back to setitimer.
1575 (Fprofiler_cpu_start): Use it.
1576 (Fprofiler_cpu_stop): Prefer timer_settime if available.
1577 Don't assume that passing NULL as the 2nd argument of setitimer
1578 is the same as passing a pointer to all-zero storage.
1579 Ignore SIGPROF afterwards.
1580 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
1581 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
1582 non-fatal signal handlers. Ignore SIGPROF on startup.
1583 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
1584 in profiler.c, since sysdep.c now uses it.
1586 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

1641 * charset.c, charset.h (maybe_unify_char): Now static.
1642 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
1643 Since this stuff is now private to charset.c, there's no need for
1644 a public macro and no need to inline by hand.

1716 (sigaction): Rewrite to call sys_signal instead of duplicating its
1718 (sys_kill): Improve commentary.
1720 * w32.c (term_ntproc): Accept (and ignore) one argument, for
1721 consistency with a signature of a signal handler. All callers
1723 (init_ntproc): Accept an argument DUMPING. If dumping, don't
1724 install term_ntproc as a signal handler for SIGABRT, as that
1725 should be done by the dumped Emacs.
1727 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
1729 * w32select.c (term_w32select): Protect against repeated
1730 invocation by setting clipboard_owner to NULL after calling

1848 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
1849 fatal_error_backtrace.
1851 * w32proc.c (sys_kill): Undo last change: don't do anything when

1853 handled by emacs_raise.
1855 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
1857 * w32term.c (w32_read_socket): Remove leftover reference to

1899 Simplify and avoid signal-handling races (Bug#12471).
1901 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
1902 Avoid recursive loop if there's a fatal error in the function itself.
1903 * atimer.c (pending_atimers):
1904 * blockinput.h: Don't include "atimer.h"; no longer needed.
1905 (interrupt_input_pending): Remove. All uses removed.
1906 pending_signals now counts both atimers and ordinary interrupts.
1907 This is less racy than having three separate pending-signal flags.
1908 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
1910 Rename from their upper-case counterparts BLOCK_INPUT,
1911 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
1912 INPUT_BLOCKED_P, and turn into functions. All uses changed.
1913 This makes it easier to access volatile variables more accurately.
1914 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
1915 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
1916 that's more reliable if the code is buggy and sets
1917 interrupt_input_blocked to a negative value. All uses changed.
1918 * atimer.c (deliver_alarm_signal):
1919 Remove. No need to deliver this to the parent; any thread can
1920 handle this signal now. All uses replaced by underlying handler.
1921 * atimer.c (turn_on_atimers):
1922 * dispnew.c (handle_window_change_signal):
1923 * emacs.c (handle_danger_signal):
1924 * keyboard.c (kbd_buffer_get_event):
1925 Don't reestablish signal handler; not needed with sigaction.
1926 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
1928 Rework to avoid unnecessary accesses to volatile variables.
1929 (UNBLOCK_INPUT_TO): Now a function.
1930 (totally_unblock_input, unblock_input): New decls.
1931 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
1932 (init_data): Remove. Necessary stuff now done in init_signal.
1933 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
1934 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
1935 (fatal_error_code): Remove; no longer needed.
1936 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
1937 it doesn't always backtrace. All uses changed. No need to reset
1938 signal to default, since sigaction and/or die does that for us now.
1939 Use emacs_raise (FOO), not kill (getpid (), FOO).
1940 (main): Check more-accurately whether we're dumping.
1941 Move fatal-error setup to sysdep.c
1942 * floatfns.c: Do not include "syssignal.h"; no longer needed.
1943 * gtkutil.c (xg_get_file_name, xg_get_font):
1944 Remove no-longer-needed signal-mask manipulation.
1945 * keyboard.c, process.c (POLL_FOR_INPUT):
1946 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
1947 * keyboard.c (read_avail_input): Remove.
1948 All uses replaced by gobble_input.
1949 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
1950 (kbd_buffer_store_event_hold, gobble_input):
1951 (record_asynch_buffer_change) [USABLE_SIGIO]:
1952 (store_user_signal_events):
1953 No need to mess with signal mask.
1954 (gobble_input): If blocking input and there are terminals, simply
1955 set pending_signals to 1 and return. All hooks changed to not
1956 worry about whether input is blocked.
1957 (process_pending_signals): Clear pending_signals before processing
1958 them, in case a signal comes in while we're processing.
1959 By convention callers now test pending_signals before calling us.
1960 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
1961 New functions, to support changes to blockinput.h.
1962 (handle_input_available_signal): Now extern.
1963 (reinvoke_input_signal): Remove. All uses replaced by
1965 (quit_count): Now volatile, since a signal handler uses it.
1966 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
1967 All callers changed. Block SIGINT only if not already blocked.
1968 Clear sigmask reliably, even if Fsignal returns, which it can.
1969 Omit unnecessary accesses to volatile var.
1970 (quit_throw_to_read_char): No need to restore sigmask.
1971 * keyboard.c (gobble_input, handle_user_signal):
1972 * process.c (wait_reading_process_output):
1973 Call signal-handling code rather than killing ourselves.
1974 * lisp.h: Include <float.h>, for...
1975 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
1976 (pending_signals): Now volatile.
1977 (syms_of_data): Now const if IEEE floating point.
1978 (handle_input_available_signal) [USABLE_SIGIO]:
1979 (terminate_due_to_signal, record_child_status_change): New decls.
1980 * process.c (create_process): Avoid disaster if memory is exhausted
1981 while we're processing a vfork, by tightening the critical section
1983 (send_process_frame, process_sent_to, handle_pipe_signal)
1984 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
1986 (send_process): No need for setjmp/longjmp any more, since the
1987 SIGPIPE stuff is now gone. Instead, report an error if errno
1989 (record_child_status_change): Now extern. PID and W are now args.
1990 Return void, not bool. All callers changed.
1991 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
1992 Remove. All uses removed. This bug should be fixed now in a
1994 (wait_for_termination_1): Use waitpid rather than sigsuspend,
1995 and record the child status change directly. This avoids the
1996 need to futz with the signal mask.
1997 (process_fatal_action): Move here from emacs.c.
1998 (emacs_sigaction_flags): New function, containing
1999 much of what used to be in emacs_sigaction_init.
2000 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
2001 caught by emacs, to make races less likely.
2002 (deliver_process_signal): Rename from handle_on_main_thread.
2004 (BACKTRACE_LIMIT_MAX): Now at top level.
2005 (thread_backtrace_buffer, threadback_backtrace_pointers):
2007 (deliver_thread_signal, deliver_fatal_thread_signal):
2008 New functions, for more-accurate delivery of thread-specific signals.
2009 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
2010 (deliver_arith_signal): Handle in this thread, not
2011 in the main thread, since it's triggered by this thread.
2012 (maybe_fatal_sig): New function.
2013 (init_signals): New arg DUMPING so that we can be more accurate
2014 about whether we're dumping. Caller changed.
2015 Treat thread-specific signals differently from process-general signals.
2016 Block all signals while handling fatal error; that's safer.
2017 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
2019 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
2020 Ignore SIGPIPE unless batch.
2021 (emacs_backtrace): Output backtrace for the appropriate thread,
2022 which is not necessarily the main thread.
2023 * syssignal.h: Include <stdbool.h>.
2024 (emacs_raise): New macro.
2025 * xterm.c (x_connection_signal): Remove; no longer needed
2026 now that we use sigaction.
2027 (x_connection_closed): No need to mess with sigmask now.
2028 (x_initialize): No need to reset SIGPIPE handler here, since
2029 init_signals does this for us now.
2031 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
2033 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
2034 background rect may be larger (Bug#12245).
2036 2012-09-23 Chong Yidong <cyd@gnu.org>
2038 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
2040 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
2042 * .gdbinit: Just stop at fatal_error_backtrace.
2043 See Stefan Monnier's request in
2044 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
2045 Remove no-longer-used query of system type.
2047 2012-09-22 Chong Yidong <cyd@gnu.org>
2049 * search.c (Freplace_match): Doc fix (Bug#12325).
2051 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
2053 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
2054 (Fline_end_position): Doc fix.
2056 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
2058 2012-09-22 Chong Yidong <cyd@gnu.org>
2060 * dispextern.h (struct image_type): Add new slot, storing a type
2061 initialization function.
2063 * image.c (define_image_type): Call the image initializer function
2064 if it is defined. Arguments and return value changed.
2065 (valid_image_p, make_image): Callers changed.
2066 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
2067 (gif_type, imagemagick_type, svg_type, gs_type):
2068 Add initialization functions.
2069 (Finit_image_library): Call lookup_image_type.
2070 (CHECK_LIB_AVAILABLE): Macro deleted.
2071 (lookup_image_type): Call define_image_type here, rather than via
2072 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
2073 (syms_of_image): Move define_image_type calls for xbm_type and
2074 pbm_type to lookup_image_type.
2076 2012-09-22 Eli Zaretskii <eliz@gnu.org>
2078 * keyboard.c (timer_check_2): Move calculation of 'timers' and
2079 'idle_timers' from here ...
2080 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
2081 lists, to avoid infloops when the timer does something stupid,
2082 like reinvoke itself with the same or smaller time-out.
2085 2012-09-22 Martin Rudalics <rudalics@gmx.at>
2087 * window.c (Fsplit_window_internal): Handle only Qt value of
2088 Vwindow_combination_limit separately.
2089 (Qtemp_buffer_resize): New symbol.
2090 (Vwindow_combination_limit): New default value.
2093 2012-09-22 Eli Zaretskii <eliz@gnu.org>
2095 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
2096 the new overlay string. (Bug#10159)
2098 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
2100 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
2101 or that fprintf is async-signal-safe. POSIX doesn't require
2104 2012-09-22 Chong Yidong <cyd@gnu.org>
2106 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
2109 2012-09-22 Kenichi Handa <handa@gnu.org>
2111 * composite.c (composition_reseat_it): Handle the case that a
2112 grapheme cluster is not covered by a single font (Bug#12352).
2114 2012-09-21 Chong Yidong <cyd@gnu.org>
2116 * image.c (define_image_type): Avoid adding duplicate types to
2117 image_types (Bug#12463). Suggested by Jörg Walter.
2119 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2121 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
2122 (print_load_command_name): Add case LC_DATA_IN_CODE.
2123 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
2125 2012-09-21 Glenn Morris <rgm@gnu.org>
2127 * eval.c (Frun_hook_with_args_until_success)
2128 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
2130 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
2132 * fileio.c (Ffile_selinux_context): Only call freecon when
2133 lgetfilecon succeeded.
2134 (Fset_file_selinux_context): Likewise. (Bug#12444)
2136 2012-09-21 Eli Zaretskii <eliz@gnu.org>
2138 * xdisp.c (try_window_reusing_current_matrix): Under bidi
2139 reordering, locate the cursor by calling set_cursor_from_row; if
2140 that fails, clear the desired glyph matrix before returning a
2141 failure indication to the caller. Fixes leaving garbled display
2142 when fast scrolling with a down-key. (Bug#12403)
2143 (compute_stop_pos_backwards): Fix a typo that caused crashes while
2144 scrolling through multibyte text.
2146 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
2148 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
2149 calling mark_vectorlike since that's the one that marks the window.
2150 (mark_discard_killed_buffers): Mark the final cdr.
2151 * window.h (struct window): Move prev/next_buffers to the
2152 non-standard fields.
2153 * window.c (make_window): Initialize prev/next_buffers manually.
2155 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
2157 Omit unused arg EXPECTED from socket hooks.
2158 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
2159 * nsterm.m (ns_term_init):
2160 * termhooks.h (struct terminal.read_socket_hook):
2161 * w32inevt.c (w32_console_read_socket):
2162 * w32term.c (w32_read_socket):
2163 * xterm.c (XTread_socket):
2164 Omit unused arg EXPECTED. All callers changed.
2165 (store_user_signal_events): Return void, not int, since callers no
2166 longer care about the return value. All uses changed.
2168 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
2170 * w32gui.h (XParseGeometry): Do not declare.
2172 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
2174 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
2175 Ignore 'expected'. See Eli Zaretskii in
2176 <http://bugs.gnu.org/12471#8> (last line).
2178 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
2179 (XParseGeometry): Now static. Substitute extremal values for
2180 values that are out of range.
2182 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
2184 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
2186 * nsfns.m (XParseGeometry): Remove.
2187 (Fx_create_frame): Call x_set_offset to correctly interpret
2188 top_pos in geometry.
2190 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
2191 (Fx_parse_geometry): If there is a space in string, call
2192 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
2194 2012-09-17 Eli Zaretskii <eliz@gnu.org>
2196 * search.c (scan_buffer): Use character positions in calls to
2197 region_cache_forward and region_cache_backward, not byte
2198 positions. (Bug#12196)
2200 * w32term.c (w32_read_socket): Set pending_signals to 1, like
2201 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
2203 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
2204 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
2205 emacs_blocked_malloc, now deleted.
2207 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
2209 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
2210 The workaround was for improving performance on Solaris 2.4, but
2211 is getting in the way now. Emacs will still work if someone is
2212 still running Solaris 2.4 in a museum somewhere; Sun dropped
2213 support for Solaris 2.4 in 2003.
2214 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
2215 * process.c (create_process) [HAVE_WORKING_VFORK]:
2216 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
2217 since Emacs no longer uses vfork on that platform.
2219 2012-09-17 Glenn Morris <rgm@gnu.org>
2221 * emacs.c: Use COPYRIGHT.
2223 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
2225 Remove configure's --without-sync-input option (Bug#12450).
2226 When auditing signal-handling in preparation for cleaning it up,
2227 I found that SYNC_INPUT has race conditions and would be a real
2228 pain to fix. Since it's an undocumented and deprecated
2229 configure-time option, now seems like a good time to remove it.
2230 Also see <http://bugs.gnu.org/11080#16>.
2231 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
2232 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
2233 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
2234 (malloc_hysteresis):
2235 (check_depth) [XMALLOC_OVERRUN_CHECK]:
2236 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
2237 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
2238 (dont_register_blocks, bytes_used_when_reconsidered)
2239 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
2240 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
2241 [!SYSTEM_MALLOC && !SYNC_INPUT]:
2242 Remove. All uses removed.
2243 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
2244 implementation, one that depends on whether the new macro
2245 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
2247 * atimer.c (run_timers, handle_alarm_signal):
2248 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
2249 (handle_async_input, process_pending_signals)
2250 (handle_input_available_signal, init_keyboard):
2251 * nsterm.m (ns_read_socket):
2252 * process.c (wait_reading_process_output):
2253 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
2254 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
2256 * xterm.c (XTread_socket):
2258 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
2259 * eval.c (handling_signal): Remove. All uses removed.
2260 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
2261 All uses replaced with the SYNC_INPUT version.
2262 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
2264 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2267 * font.c (Ffont_shape_gstring): Remove unused local.
2269 2012-09-16 Glenn Morris <rgm@gnu.org>
2271 * Makefile.in (clean): No longer run nextstep's clean.
2273 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
2275 (ns-app): Move here from ns.mk, and simplify.
2276 (clean): Simplify nextstep entry.
2277 * ns.mk: Remove file.
2279 2012-09-17 Kenichi Handa <handa@gnu.org>
2281 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
2282 not covert the last few charactes.
2284 2012-09-16 Kenichi Handa <handa@gnu.org>
2286 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
2287 here, but just check the validity of glyphs in the glyph-string.
2289 2012-09-16 Martin Rudalics <rudalics@gmx.at>
2291 * window.c (Fwindow_parameter, Fset_window_parameter):
2292 Accept any window as argument (Bug#12452).
2294 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
2296 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
2297 to ns_term_init to avoid memory leak.
2299 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
2300 explicit retain/release.
2301 (ns_term_init): Only allow one display. Initialize outerpool and
2304 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
2306 Port _setjmp fix to POSIXish hosts as well as Microsoft.
2307 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
2308 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
2309 the Microsoft problem in a different way, by altering ../nt/config.nt.
2311 2012-09-15 Eli Zaretskii <eliz@gnu.org>
2326 * w16select.c: Remove inclusion of setjmp.h, as it is now included
2327 by lisp.h. This completes removal of setjmp.h inclusion
2328 erroneously announced in the previous commit. (Bug#12446)
2330 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
2333 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
2334 not defined as a macro. The latter happens on MS-Windows.
2337 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
2339 Port better to POSIX hosts lacking _setjmp (Bug#12446).
2340 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
2341 Some instances of '#include <setjmp.h>' removed, if the
2342 only reason for the instance was because "lisp.h" was included.
2343 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
2344 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
2345 and _longjmp with the new symbols. Emacs already uses _setjmp if
2346 available, so this change affects only POSIXish hosts that have
2347 sigsetjmp but not _setjmp, such as some versions of Solaris and
2348 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
2349 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
2350 (png_load_body) [HAVE_PNG]:
2351 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
2352 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
2353 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
2354 since PNG requires jmp_buf. This is the only exception to the
2355 general rule that we now use sys_setjmp and sys_longjmp.
2356 This exception is OK since this code does not change the signal
2357 mask or longjmp out of a signal handler.
2359 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
2361 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
2362 Include "syssignal.h", for 'main_thread'.
2364 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
2366 Avoid out-of-range marker position (Bug#12426).
2367 * insdel.c (replace_range, replace_range_2):
2368 Adjust markers before overlays, as suggested by comments.
2369 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
2370 Remove redundant check before calling offset_intervals.
2372 2012-09-14 Martin Rudalics <rudalics@gmx.at>
2374 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
2375 current buffer (Bug#12387).
2377 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
2379 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
2381 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
2383 Use a more backwards-compatible timer format (Bug#12430).
2384 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
2385 vector element, not from the 4th, since PSECS is now at the end.
2386 (Fcurrent_idle_time): Doc fix.
2388 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
2390 Function to mark objects and remove killed buffers at once.
2391 * alloc.c (discard_killed_buffers): Rename to ...
2392 (mark_discard_killed buffers) ... new name. Add marking
2393 of remaining objects. Fix comment. Adjust users.
2394 (mark_object): Do not touch frame buffer lists here.
2395 * frame.c (delete_frame): Reset frame buffer lists here.
2397 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
2399 Better workaround for GNOME bug when --enable-gcc-warnings.
2400 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
2401 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
2402 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
2404 Simplify SIGIO usage (Bug#12408).
2405 The code that dealt with SIGIO was crufty and confusing, e.g., it
2406 played tricks like "#undef SIGIO" but these tricks were not used
2407 consistently. Simplify mostly by not #undeffing standard symbols,
2408 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
2409 or not as we please) rather than "defined SIGIO" (standard symbol
2410 that we probably shouldn't #undef).
2411 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
2412 Modules that need it can include it.
2413 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
2414 * dispextern.h (ignore_sigio): New decl.
2415 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
2416 unconditionally, since it's now a no-op if !USABLE_SIGIO.
2417 * emacs.c (shut_down_emacs):
2418 * keyboard.c (kbd_buffer_store_event_hold):
2419 Use ignore_sigio rather than invoking 'signal' directly.
2420 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
2422 (FIONREAD, SIGIO): Do not #undef.
2423 (tty_read_avail_input): Use #error rather than a syntax error.
2424 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
2425 for I_PIPE, used by SETUP_SLAVE_PTY.
2426 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
2427 * sysdep.c (croak): Remove; no longer needed. This bit of
2428 temporary code, with Fred N. Fish's comment that it's temporary,
2429 has been in Emacs since at least 1992!
2430 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
2431 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
2432 * syssignal.h (croak): Remove decl.
2433 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
2434 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
2435 now that we're termios-only.
2436 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
2437 * term.c (dissociate_if_controlling_tty): Use #error rather than
2440 Work around GCC and GNOME bugs when --enable-gcc-warnings.
2441 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
2442 to work around GNOME bug 683906.
2443 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
2444 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
2445 This works around GCC bug 54561.
2447 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
2449 More fixes for 'volatile' and setjmp/longjmp.
2450 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
2451 * image.c (struct png_load_context) [HAVE_PNG]: New type.
2452 (png_load_body) [HAVE_PNG]:
2453 (jpeg_load_body) [HAVE_JPEG]:
2454 New function, with most of the old parent function's body.
2455 (png_load) [HAVE_PNG]:
2456 (jpeg_load) [HAVE_JPEG]:
2457 Invoke the new function, to avoid longjmp munging our locals.
2458 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
2459 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
2460 longjmp is passed 2, as the C standard doesn't guarantee this.
2461 Instead, store the failure code into mgr->failure_code.
2463 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
2465 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
2466 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
2467 (syms_of_keyboard): Remove support for unread-command-char.
2469 2012-09-12 Eli Zaretskii <eliz@gnu.org>
2471 * w32proc.c (sys_kill): If PID is our process ID and the signal is
2472 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
2473 violation. (Bug#12426)
2475 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
2477 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
2479 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
2481 * eval.c: Add `inhibit-debugger'.
2482 (Qinhibit_debugger): New symbol.
2483 (call_debugger): Bind it instead of Qdebug_on_error.
2484 (maybe_call_debugger): Test Vinhibit_debugger.
2485 (syms_of_eval): Define inhibit-debugger.
2486 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
2487 (syms_of_xdisp): Remove inhibit-debug-on-message.
2489 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
2491 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
2492 If a nonvolatile local variable is written before a _longjmp to
2493 the frame containing the variable, and is read after the _longjmp,
2494 the value read is indeterminate. Some local variables of type
2495 'struct handler' and 'struct catchtag' are used in this way, so
2496 mark each of their slots as volatile if the slot can be set before
2497 _longjmp and read afterwards.
2498 * lisp.h (struct handler): var and chosen_clause are now volatile.
2499 (struct catchtag): val, next, and pdlcount are now volatile.
2501 * bidi.c (bidi_push_it, bidi_pop_it):
2502 * fns.c (copy_hash_table):
2503 * image.c (define_image_type):
2504 * keyboard.c (kbd_buffer_store_event_hold):
2505 * process.c (Fprocess_send_eof):
2506 * xfaces.c (x_create_gc) [HAVE_NS]:
2507 * xgselect.c (xg_select):
2508 Prefer assignment to memcpy when either will do.
2510 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
2511 Use pointer-to-a-pointer to simplify and avoid a NILP check each
2512 time an item is removed. No need to mark this function 'inline';
2513 the compiler knows better than we do.
2515 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
2517 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
2518 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
2519 to change_frame_size (Bug#12388).
2520 (windowDidResize:): Pass YES to updateFrameSize.
2522 * nsterm.h: Add delay parameter to updateFrameSize.
2524 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
2526 Discard killed buffers from deleted window and frame objects.
2527 This reduces an amount of references to killed buffers and
2528 helps GC to reclaim them faster.
2529 * alloc.c (discard_killed_buffers): New function.
2530 (mark_object): Use it for deleted windows and frames.
2531 (mark_object): If symbol's value is set up for a killed buffer
2532 or deleted frame, restore its global binding.
2533 * data.c (swap_in_global_binding): Add GC notice.
2534 (swap_in_symval_forwarding): Use convenient set_blv_where.
2535 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
2536 * window.h: ... to here.
2538 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
2540 Convenient macro to check whether the buffer is live.
2541 * buffer.h (BUFFER_LIVE_P): New macro.
2542 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
2543 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
2545 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2547 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
2548 composition cases (Bug#12364).
2550 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
2551 overhang of succeeding glyphs overlapping box cursor.
2553 * w32term.c (x_draw_glyph_string): Likewise.
2555 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
2557 Simplify, document, and port floating-point (Bug#12381).
2558 The porting part of this patch fixes bugs on non-IEEE platforms
2559 with frexp, ldexp, logb.
2560 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
2562 * floatfns.c: Simplify discussion of functions that Emacs doesn't
2563 support, by removing commented-out code and briefly listing the
2564 C89 functions excluded. The commented-out stuff was confusing
2565 maintenance, e.g., we thought we needed cbrt but it was commented out.
2566 (logb): Remove decl; no longer needed.
2567 (isfinite): New macro, if not already supplied.
2568 (isnan): Don't replace any existing macro.
2569 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
2570 are present on all C89 platforms.
2571 (Ffrexp): Do not special-case zero, as frexp does the right thing
2573 (Flogb): Do not use logb, as it doesn't have the desired meaning
2574 on hosts that use non-base-2 floating point. Instead, stick with
2575 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
2576 frexp, to avoid getting an unspecified result.
2578 * xdisp.c (Qinhibit_debug_on_message): Now static.
2580 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
2582 * nsterm.m (ns_update_begin): Set clip path to whole view by using
2583 NSBezierPath (Bug#12131).
2585 2012-09-10 Chong Yidong <cyd@gnu.org>
2587 * fns.c (Fdelq, Fdelete): Doc fix.
2589 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
2591 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
2592 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
2594 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
2596 * lisp.h (make_lisp_ptr): New macro to replace XSET.
2597 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
2600 2012-09-09 Eli Zaretskii <eliz@gnu.org>
2602 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
2603 left fringe if the window has a left margin. This avoids leaving
2604 traces of the cursor because its leftmost pixel is not drawn over.
2606 * dispnew.c (update_window_line): When the left margin area of a
2607 screen line is updated, set the redraw_fringe_bitmaps_p flag of
2608 that screen line. (Bug#12277)
2610 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
2612 Assume C89 or later for math functions (Bug#12381).
2613 This simplifies the code, and makes it a bit smaller and faster,
2614 and (most important) makes it easier to clean up signal handling
2615 since we can stop worring about floating-point exceptions in
2616 library code. That was a problem before C89, but the problem
2617 went away many years ago on all practical Emacs targets.
2618 * data.c, image.c, lread.c, print.c:
2619 Don't include <math.h>; no longer needed.
2620 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
2621 might be autoconfigured, as that never happens.
2623 * doprnt.c (DBL_MAX_10_EXP):
2624 * print.c (DBL_DIG):
2625 Remove. C89 or later always defines these.
2626 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
2627 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
2628 (arith_error, domain_error, domain_error2):
2629 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
2630 no longer needed -- we simply return what C returns. All uses removed.
2631 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
2633 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
2634 Remove. All uses expanded, as these macros are no longer used
2635 more than once and are now more trouble than they're worth.
2636 (Ftan): Use tan, not sin / cos.
2637 (Flogb): Assume C89 frexp.
2638 (fmod_float): Assume C89 fmod.
2639 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
2640 (init_floatfns): Remove. All uses removed.
2642 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2644 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
2645 compositeToPoint for OSX < 10.6 (Bug#12390).
2647 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
2649 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
2650 This produces more-accurate results.
2652 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2654 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
2655 changes (Bug#12088).
2657 2012-09-08 Chong Yidong <cyd@gnu.org>
2659 * syntax.c (Fstring_to_syntax): Doc fix.
2661 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2663 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
2664 in the internal border.
2665 (x_set_window_size): Remove static variables and their usage.
2666 (ns_redraw_scroll_bars): Fix NSTRACE arg.
2667 (ns_after_update_window_line, ns_draw_fringe_bitmap):
2668 Remove fringe/internal border adjustment (Bug#11052).
2669 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
2670 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
2671 (ns_fix_rect_ibw): Remove.
2672 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
2673 (ns_dumpglyphs_box_or_relief): Ditto.
2674 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
2676 (ns_dumpglyphs_image): Ditto.
2677 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
2679 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
2680 their usage. Add fringe_extended_p and its use as in other terms.
2681 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
2682 scroll bar was removed.
2683 (updateFrameSize): New function.
2684 (windowDidResize): Move code to updateFrameSize and call it.
2686 * nsterm.h (EmacsView): Add updateFrameSize.
2688 2012-09-07 Chong Yidong <cyd@gnu.org>
2690 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
2692 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
2694 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
2696 More signal-handler cleanup (Bug#12327).
2697 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
2698 Problem introduced when merging patches. Noted by Eli Zaretskii in
2699 <http://bugs.gnu.org/12327#67>.
2700 * floatfns.c: Comment fix.
2701 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
2702 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
2703 and anyway the declaration is harmless even if SIGDANGER is not defined.
2704 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
2705 defined BROKEN_FIONREAD). systty.h formerly did this, but other
2706 source files not surprisingly expected syssignal.h to define, or
2707 not define, SIGIO, and it's cleaner to do it that way, for consistency.
2708 Include <sys/ioctl.h>, for FIONREAD.
2709 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
2710 This eliminates a problem whereby other files mysteriously had
2711 to include "syssignal.h" before including "systty.h" if they
2712 wanted to use "#ifdef SIGIO".
2714 2012-09-07 Eli Zaretskii <eliz@gnu.org>
2716 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
2718 * w32.c (sigemptyset): Empty the set.
2719 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
2721 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
2723 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
2725 * alloc.c (mark_buffer): Revert unsafe marking optimization.
2726 (mark_object): Likewise for frame objects.
2728 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
2730 * syssignal.h (handle_on_main_thread): Always declare,
2731 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
2732 This ports to platforms without HAVE_PTHREAD.
2734 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
2736 Signal-handler cleanup (Bug#12327).
2737 Emacs's signal handlers were written in the old 4.2BSD style with
2738 sigblock and sigmask and so forth, and this led to some
2739 inefficiencies and confusion. Rewrite these to use
2740 pthread_sigmask etc. without copying signal sets around. Also,
2741 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
2742 'signal', and instead use functions that do not attempt to take
2743 over the system name space. This patch causes Emacs's text
2744 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
2745 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
2746 Do not include <signal.h> or "syssignal.h", as these
2747 modules do not use signals.
2748 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
2749 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
2750 Do not include <signal.h>, as "syssignal.h" does that for us now.
2751 * atimer.c (sigmask_atimers): New function.
2752 (block_atimers, unblock_atimers): New functions,
2753 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
2755 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
2756 no longer needed here.
2757 * emacs.c (main): Inspect existing signal handler with sigaction,
2758 so that there's no need to block and unblock SIGHUP.
2759 * sysdep.c (struct save_signal): New member 'action', replacing
2760 old member 'handler'.
2761 (save_signal_handlers, restore_signal_handlers):
2762 Use sigaction instead of 'signal' to save and restore.
2763 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
2764 New function. All users of 'signal' modified to use set_sighandler
2765 if they're writeonly, and to use sys_signal if they're read+write.
2766 (emacs_sigaction_init, forwarded_signal): New functions.
2767 (sys_signal): Remove. All uses replaced by calls to sigaction
2768 and emacs_sigaction_init, or by direct calls to 'signal'.
2769 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
2770 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
2771 all uses replaced by pthread_sigmask etc. calls.
2772 * syssignal.h: Include <signal.h>.
2773 (emacs_sigaction_init, forwarded_signal): New decls.
2774 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
2775 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
2776 (sigmask, sys_sigmask): Remove; no longer needed.
2777 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
2778 (sigblock, sigunblock, sigfree):
2779 (sigsetmask) [!defined sigsetmask]:
2780 Remove. All uses replaced by pthread_sigmask.
2781 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
2782 no longer need to be replaced, and its typical old uses
2783 are now done via emacs_sigaction_init and sigaction.
2784 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
2785 (sys_sigdel): Remove; unused.
2786 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
2788 2012-09-06 Eli Zaretskii <eliz@gnu.org>
2790 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
2791 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
2793 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
2795 Explicitly mark buffer_defaults and buffer_local_symbols.
2796 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
2797 mark_local_symbols here.
2798 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
2799 since special buffers aren't marked here any more.
2800 (allocate_buffer): Chain new buffer with all_buffers here...
2801 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
2803 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
2804 (syms_of_buffer): Remove staticpro of the above.
2805 (init_buffer_once): Set names for buffer_defaults and
2806 buffer_local_symbols.
2808 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
2810 Use bool for booleans in font-related modules.
2811 * font.c (font_intern_prop, font_style_to_value)
2812 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
2813 (generate_otf_features, font_check_otf_features, font_check_otf)
2814 (font_match_p, font_list_entities, font_at):
2815 * fontset.c (fontset_id_valid_p, reorder_font_vector
2816 (fontset_find_font, Fset_fontset_font)
2817 (face_suitable_for_char_p) [0]:
2818 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
2819 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
2820 (m17n_flt_initialized, ftfont_shape_by_flt):
2821 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
2822 * nsfont.m (nsfont_draw):
2823 * w32font.c (w32font_draw):
2824 * w32term.c (x_draw_glyphless_glyph_string_foreground):
2825 Use bool for booleans.
2826 * font.h: Adjust to above API changes.
2827 (struct font, struct font_driver, struct font_driver_list):
2828 Use bool for booleans.
2829 (struct font): Remove useless member encoding_type.
2831 * fontset.c, xftfont.c: Omit unnecessary static decls.
2833 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
2835 * alloc.c (mark_object): Revert window marking code
2836 since it's unsafe for the Fset_window_configuration.
2838 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
2840 Fix race conditions with signal handlers and errno (Bug#12327).
2841 Be more systematic about preserving errno whenever a signal
2842 handler returns, even if it's not in the main thread. Do this by
2843 renaming signal handlers to distinguish between signal delivery
2844 and signal handling. All uses changed.
2845 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
2846 * data.c (deliver_arith_signal): Rename from arith_error.
2847 * dispnew.c (deliver_window_change_signal): Rename from
2848 window_change_signal.
2849 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
2850 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
2851 * keyboard.c (deliver_input_available_signal): Rename from
2852 input_available_signal.
2853 (deliver_user_signal): Rename from handle_user_signal.
2854 (deliver_interrupt_signal): Rename from interrupt_signal.
2855 * process.c (deliver_pipe_signal): Rename from send_process_trap.
2856 (deliver_child_signal): Rename from sigchld_handler.
2857 * atimer.c (handle_alarm_signal):
2858 * data.c (handle_arith_signal):
2859 * dispnew.c (handle_window_change_signal):
2860 * emacs.c (handle_fatal_signal, handle_danger_signal):
2861 * keyboard.c (handle_input_available_signal):
2862 * keyboard.c (handle_user_signal, handle_interrupt_signal):
2863 * process.c (handle_pipe_signal, handle_child_signal):
2864 New functions, with the actual signal-handling code taken from the
2865 original respective signal handlers, sans the sporadic attempts to
2866 preserve errno, since that's now done by handle_on_main_thread.
2867 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
2868 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
2869 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2871 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2872 Move initialization of main_thread to sysdep.c's init_signals.
2873 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
2874 our usage, and simplifies the mainline code.
2875 (record_child_status_change): New static function, as a helper
2876 for handle_child_signal, and with most of the old child handler's
2878 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
2879 (handle_child_signal): Use the above.
2880 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2881 Moved here from emacs.c.
2882 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
2883 code moved here from emacs.c's main function.
2884 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
2885 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
2886 This lets callers save and restore errno properly.
2888 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2890 Remove redundant or unused things here and there.
2891 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
2892 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
2893 * editfns.c (Fcompare_buffer_substrings): Likewise.
2894 * frame.h (struct terminal, struct font_driver_list):
2895 Remove redundant declarations.
2896 * window.h (Qleft, Qright): Likewise.
2898 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2900 Do not mark objects from deleted buffers, windows and frames.
2901 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
2902 (mark_object): Likewise for windows and frames.
2904 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2906 * alloc.c (valid_lisp_object_p): Treat killed buffers,
2907 buffer_defaults and buffer_local_symbols as valid objects.
2908 Return special value to denote them.
2910 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
2912 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
2913 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
2914 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
2915 (file_name_absolute_p, Fsubstitute_in_file_name):
2916 (check_executable, check_writable, Ffile_accessible_directory_p)
2917 (Fset_file_selinux_context, Fdefault_file_modes)
2918 (Finsert_file_contents, choose_write_coding_system)
2919 (Fwrite_region, build_annotations, a_write, e_write)
2921 * filelock.c (boot_time_initialized, get_boot_time)
2922 (get_boot_time_1, lock_file_1, within_one_second):
2923 * floatfns.c (in_float):
2924 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
2925 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
2926 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
2927 * lisp.h (struct Lisp_Hash_Table.cmpfn):
2928 * window.c (compare_window_configurations):
2929 Use bool for booleans.
2930 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
2931 (Fdefault_file_modes): Now mode_t, not int, for modes.
2932 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
2933 (internal_delete_file): Now returns void, not a (boolean) int,
2934 since nobody was looking at the return value.
2935 * lisp.h, window.h: Adjust to above API changes.
2937 * xdisp.c (set_message): Simplify and reindent last change.
2939 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
2941 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
2943 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
2945 * eval.c (call_debugger): Make the function non-static so that we
2946 can call it from set_message.
2948 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
2949 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
2951 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2953 Give more-useful info on a fatal error (Bug#12328).
2954 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
2955 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
2956 of doing the work ourselves.
2957 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
2958 do most of the work.
2959 (fatal_error_backtrace): New function, taken from the guts
2960 of the old fatal_error_signal, but with a new option to output
2962 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
2963 info about the signal than just its number.
2964 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
2965 * sysdep.c: Include <execinfo.h>
2966 (emacs_backtrace): New function, taken partly from the previous
2967 code of the 'die' function.
2968 (emacs_abort): Call fatal_error_backtrace rather than abort.
2970 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
2972 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
2973 eager (load-time) macro-expansion.
2974 * lisp.mk (lisp): Add macroexp.
2976 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2978 Simplify redefinition of 'abort' (Bug#12316).
2979 Do not try to redefine the 'abort' function. Instead, redo
2980 the code so that it calls 'emacs_abort' rather than 'abort'.
2981 This removes the need for the NO_ABORT configure-time macro
2982 and makes it easier to change the abort code to do a backtrace.
2983 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
2984 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
2985 Remove; sysdep.c's emacs_abort now takes its place.
2986 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
2987 'abort' changed to use 'emacs_abort'.
2988 * msdos.c (dos_abort) [defined abort]: Remove; not used.
2989 (abort) [!defined abort]: Rename to ...
2990 (emacs_abort): ... new name.
2991 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
2992 the place of the old 'abort' in emacs.c.
2993 * w32.c, w32fns.c (abort): Do not #undef.
2994 * w32.c (emacs_abort): Rename from w32_abort.
2996 2012-09-04 Eli Zaretskii <eliz@gnu.org>
2998 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
2999 offsets[j].dv, since the y axis of the screen coordinates points
3000 down, while the y axis of the font definition coordinates points
3001 up. This fixes display of Arabic diacritics such as KASRA and
3002 KASRATAN. (Bug#11860)
3004 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3006 Be more systematic about _setjmp vs setjmp.
3007 * alloc.c (test_setjmp, mark_stack):
3008 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
3009 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
3010 (png_load, my_error_exit, jpeg_load):
3011 * process.c (send_process_trap, send_process):
3012 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
3013 The underscored versions are up to 30x faster on some hosts.
3014 Formerly, the code used setjmp+longjmp sometimes and
3015 _setjmp+_longjmp at other times, with no particular reason to
3016 prefer setjmp+longjmp.
3018 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
3020 Fix minor problem found by static checking.
3021 * buffer.c (Fdelete_all_overlays): Return nil.
3023 2012-09-03 Martin Rudalics <rudalics@gmx.at>
3025 * buffer.c (Fdelete_all_overlays): New function.
3027 2012-09-03 Chong Yidong <cyd@gnu.org>
3029 * gtkutil.c: Add extern decl for Qxft.
3031 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
3033 * emacs.c, eval.c: Use bool for boolean.
3034 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
3035 (malloc_using_checking) [DOUG_LEA_MALLOC]:
3036 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
3037 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
3038 (main, decode_env_path, Fdaemon_initialized):
3039 * eval.c (call_debugger, Finteractive_p, interactive_p):
3040 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
3041 (maybe_call_debugger, Fbacktrace):
3042 * process.c (read_process_output, exec_sentinel):
3043 Use bool for booleans.
3044 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
3045 All callers changed.
3046 * eval.c (interactive_p): Omit always-true boolean argument
3047 EXCLUDE_SUBRS_P. All callers changed.
3048 * dispextern.h, lisp.h: Reflect above API changes.
3049 * firstfile.c (dummy): Use the address of 'main', whose signature
3050 won't change, instead of the address of 'initialize', whose
3051 signature just changed from int to bool.
3052 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
3053 * msdos.c (fatal_error_in_progress): ... from here.
3054 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
3056 (redisplay_internal, unwind_redisplay): Simply clear
3057 REDISPLAYING_P when unwinding, instead of saving its previous,
3058 always-false value and then restoring it.
3060 Clean up some extern decls.
3061 Mostly, this hoists extern decls out of .c files and into .h files.
3062 That way, we're more likely to catch errors if the interfaces change.
3063 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
3064 declare xg_mark_data.
3065 * dispextern.h (x_frame_parm_handlers):
3067 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
3068 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
3069 (Qultra_bold, Qoblique, Qitalic):
3070 Move extern decl here from .c file.
3071 * alloc.c (xg_mark_data) [USE_GTK]:
3073 * eval.c (Qlexical_binding):
3074 * fns.c (time) [!HAVE_UNISTD_H]:
3075 * gtkutil.c (Qxft, Qnormal, Qextra_light, Qlight, Qsemi_light)
3076 (Qsemi_bold, Qbold, Qextra_bold, Qultra_bold, Qoblique, Qitalic):

3080 * process.c (QCfamily, QCfilter):
3081 * widget.c (free_frame_faces):
3082 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
3083 * xfont.c (x_clear_errors):
3084 * xterm.c (x_frame_parm_handlers):
3085 Remove now-redundant extern decls.
3086 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
3087 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
3089 * xfaces.c: Remove unnecessary static decls.
3090 * xterm.c (updating_frame): Remove decl of nonexistent object.
3092 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
3093 when building globals.h, as the objects that are not built on
3094 this host are not needed to compile C files on this host.
3096 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
3098 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
3100 * frame.h: Add missing prototype for x_wm_set_size_hint.
3102 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
3104 * doc.c, editfns.c, insdel.c, intervals.c: Use bool for boolean.

3106 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
3107 (Fsubstitute_command_keys):

3110 (disassemble_lisp_time, decode_time_components, emacs_nmemftime)
3111 (format_time_string, general_insert_function)
3112 (make_buffer_string, make_buffer_string_both)
3113 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):
3114 * insdel.c (check_markers, gap_left, adjust_markers_for_insert)

3121 (adjust_intervals_for_insertion, merge_properties_sticky)
3122 (graft_intervals_into_buffer, lookup_char_property)
3123 (adjust_for_invis_intang, set_point_both)

3131 2012-09-02 Chong Yidong <cyd@gnu.org>
3133 * keymap.c (push_key_description): Print M-TAB as C-M-i
3136 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
3138 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
3139 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

3144 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
3146 2012-09-01 Eli Zaretskii <eliz@gnu.org>
3148 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
3149 more than one grapheme cluster passed to the shaper: compute the
3150 offset adjustment values separately for each cluster. (Bug#11860)
3152 * image.c: Restore mistakenly removed inclusion of w32.h. Without
3153 it, GCC doesn't see prototypes of w32_delayed_load, and complains
3154 about implicit conversions from integer to pointer.
3156 2012-09-01 Daniel Colascione <dancol@dancol.org>
3158 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
3159 system used too early.
3161 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
3163 Better seed support for (random).
3164 * emacs.c (main): Call init_random.
3165 * fns.c (Frandom): Set the seed from a string argument, if given.
3166 Remove long-obsolete Gentzel cruft.

3168 (init_random): New function.
3170 2012-09-01 Daniel Colascione <dancol@dancol.org>
3172 * xterm.h: Add header guards. Declare x_menubar_window_to_frame.
3173 Remove x_set_frame_alpha, x_bitmap_icon, x_make_frame_visible,
3174 x_make_frame_invisible, x_iconify_frame, x_free_frame_resources,
3175 x_wm_set_size_hint, x_query_colors, x_real_positions,
3176 x_set_menu_bar_lines, x_char_width, x_char_height, x_sync,
3177 x_set_tool_bar_lines, x_activate_menubar, and free_frame_menubar,
3178 all of which have been moved to common code.
3180 * xfaces.c: Include TERM_HEADER instead of listing all possible
3181 window-system headers.
3183 * w32xfns.c (x_sync): Correct definition of x_sync (a no-op here)
3186 * w32term.h (FRAME_X_WINDOW): Use FRAME_W32_WINDOW instead of
3187 directly accessing frame internals.
3189 * w32font.h: Include font.h. Define syms_of_w32font and
3192 * process.c: Include TERM_HEADER instead of listing all possible
3193 window-system headers.
3195 * nsterm.h: Remove declarations now in frame.h.
3196 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
3198 * menu.c: Include TERM_HEADER instead of listing all possible
3199 window-system headers.
3201 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
3204 * keyboard.c: Include TERM_HEADER instead of listing all possible
3205 window-system headers.
3207 * image.c: Include TERM_HEADER instead of listing all possible
3208 window-system headers. Declare Vlibrary_cache when compiling for
3211 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
3212 window system declarations.
3214 * frame.h: Move common functions here: set_frame_menubar,
3215 x_set_window_size, x_sync, x_get_focus_frame,
3216 x_set_mouse_position, x_set_mouse_pixel_position,
3217 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,
3218 x_char_width, x_char_height, x_pixel_width, x_pixel_height,

3244 * lisp.h (mark_ttys): Remove prototype.
3245 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call

3268 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
3269 does not become zero (Bug#12234).
3271 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>

3279 source directory's site-lisp dir to the load-path if it exists,
3280 consistent with in-tree builds. (Bug#12302)
3282 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
3284 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize

3299 (timeout_handler:): Set timer_fired to YES.
3300 (runDialogAt:): Set timer_fired to NO.
3301 Handle click on close button as quit.
3303 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
3304 Add window_closed and button_values. Add void as return value for
3305 add(Button|String|Split). addButton takes int instead of Lisp_Object.
3306 Add process_dialog as new member.
3308 2012-08-28 Eli Zaretskii <eliz@gnu.org>
3310 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it

3388 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
3390 * nsterm.h (NSPanel): New class variable dialog_return.

3446 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
3447 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
3448 not a boolean 'int', since callers never look at the return value.

3450 * coding.h (decoding_buffer_size, encoding_buffer_size)
3451 (emacs_mule_string_char): Remove unused extern decls.
3452 (struct iso_2022_spec, struct coding_system):

3460 Fix spare memory change (Bug#12286).
3461 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
3462 (valid_lisp_object_p): Likewise.
3464 2012-08-27 Martin Rudalics <rudalics@gmx.at>
3466 * window.c (Fset_window_configuration): Record any window's old
3467 buffer if it's replaced (see Bug#8789). If the new current
3468 buffer doesn't appear in the selected window, go to its old
3471 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
3473 Special MEM_TYPE_SPARE to denote reserved memory.
3474 * alloc.c (enum mem_type): New memory type.
3475 (refill_memory_reserve): Use new type for spare memory.
3476 This prevents live_cons_p and live_string_p from incorrect

3479 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
3482 * Makefile.in (.PHONY): versioclean -> versionclean.

3486 * window.c (Qwindow_valid_p, decode_valid_window):
3487 Now static, not extern.

3505 (map_sub_char_table):
3506 Use bool for boolean.

3508 always 0. All callers changed.
3509 * character.h, charset.h: Adjust to match previous changes.
3510 * character.h (char_printable_p): Remove decl of nonexistent function.
3511 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
3512 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
3513 are all boolean, so make them single-bit bitfields.
3515 * lisp.h (ASET): Remove attempt to detect side effects.
3516 It was meant to be temporary and it often doesn't work,
3517 because when IDX has side effects the behavior of IDX==IDX
3518 is undefined. See Stefan Monnier in
3519 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
3521 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)

3524 (FUNCTIONP): Use it.
3525 * eval.c (Ffunctionp): Use it.
3527 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
3529 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
3530 as that's faster and simpler than static storage. Don't bother
3531 with the g_main_context_query overhead if g_main_context_pending
3532 says no events are pending.
3533 (gfds, gfds_size): Remove these static vars.
3534 (xgselect_initialize): Remove; no longer needed.
3535 All uses and decls removed.
3537 * emacs.c (fatal_error_signal_hook): Remove.
3538 All uses removed. This leftover from old code was always 0.
3540 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
3541 * casefiddle.c (casify_object, casify_region):
3542 * casetab.c (set_case_table):

3565 Use bool for booleans, instead of int.
3566 * lisp.h, process.h: Adjust prototypes to match above changes.
3567 * callint.c (Fcall_interactively): Don't assume the mark's
3568 offset fits in 'int'.

3580 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
3581 Use bool for booleans, instead of int.
3582 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
3583 since the 1-or-0 return value is always ignored anyway.
3584 (mmap_initialized_p):
3585 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
3586 * buffer.h, lisp.h: Adjust prototypes to match above changes.
3588 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
3590 * bidi.c: Use bool for boolean.
3591 This is a bit more readable, and makes the text segment of bidi.o
3592 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
3593 Presumably it's faster too.

3627 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
3629 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
3630 Otherwise, the compiler complains about (A?B:C) where B is void
3631 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
3632 (fontset_add): Return void, for FONTSET_ADD.
3634 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>

3665 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
3666 (set_fontset_default, set_fontset_fallback): Rename from their
3667 upper-case counterparts, and make them functions rather than macros.
3668 This is more consistent with the other recently-introduced setters.
3669 These don't need to be inline, since they're local.
3671 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
3673 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in

3676 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3678 * lisp.h (vcopy): Use memcpy rather than our own loop.
3679 This fixes a performance regression introduced by the recent
3680 addition of vcopy. This means 'vcopy' will need to be modified
3681 for a copying collector, but that's OK. Also, tighten the
3682 checking in the assertion.
3684 2012-08-21 Eli Zaretskii <eliz@gnu.org>
3686 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
3687 components for RTL text (Bug#11860). Adjust X-OFFSET of each
3688 non-base glyph for the width of the base character, according to
3689 what x_draw_composite_glyph_string_foreground expects.
3690 Generate WADJUST value according to composition_gstring_width's
3691 expectations, to produce correct width of the composed character.
3692 Reverse the sign of the DU offset produced by ScriptPlace.
3694 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3696 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
3698 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
3700 Avoid direct writes to contents member of struct Lisp_Vector.
3701 * lisp.h (vcopy): New function to copy data into vector.

3717 buffer to the specified position.
3719 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>

3722 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
3723 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
3724 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
3727 2012-08-20 Glenn Morris <rgm@gnu.org>
3729 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
3730 Don't assume that `ln -f' works.
3732 2012-08-20 Eli Zaretskii <eliz@gnu.org>
3734 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
3735 and later about non-assignments with no effect. See discussion at
3736 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
3739 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3741 Inline setter functions for Lisp_Objects slots of struct specbinding.
3742 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
3745 2012-08-20 Martin Rudalics <rudalics@gmx.at>
3747 * window.c (select_window): Always make selected window's buffer
3750 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>

3755 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
3757 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3759 Inline setter functions for hash table members.
3760 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
3761 (set_hash_hash, set_hash_index): Rename with _slot suffix.
3762 (set_hash_key_and_value, set_hash_index, set_hash_next)
3763 (set_hash_hash): New functions.
3764 * charset.c, fns.c: Adjust users.
3766 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3768 Inline getter and setter functions for per-buffer values.

3772 * buffer.c, data.c: Adjust users.
3774 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
3776 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
3778 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
3780 Rely on <config.h> + <unistd.h> to declare 'environ',
3781 as gnulib does this if the system doesn't.
3782 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
3783 Remove declaration. MS-Windows declares it on stdlib.h which is
3784 included by conf_post.h.
3785 * emacs.c (environ) [DOUG_LEA_MALLOC]:
3786 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
3787 * vm-limit.c: Include <unistd.h>, for 'environ'.
3789 * unexaix.c, unexcoff.c: Include "mem-limits.h".
3790 (start_of_data): Remove decl; mem-limits.h provides it.
3792 * xdisp.c (handle_invisible_prop): Make it a bit faster
3793 and avoid a gcc -Wmaybe-uninitialized diagnostic.
3795 2012-08-19 Chong Yidong <cyd@gnu.org>
3797 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
3800 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>

3805 * data.c (set_internal): Don't use set_blv_found.
3806 (Fkill_local_variable): Likewise.
3808 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
3810 * nsfont.m (ns_ascii_average_width): Ensure the string
3811 ascii_printable is initialized with a null-terminated character
3812 array. Otherwise, it can contain undesired extra characters.
3814 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
3816 port new setting code to Sun C 5.8 2005/10/13
3817 * chartab.c, lisp.h (char_table_set, char_table_set_range):
3818 Return void, not Lisp_Object. Otherwise, the compiler
3819 complains about (A?B:C) where B is void and C is Lisp_Object
3820 when compiling CHAR_TABLE_SET, due to the recent change to
3821 the API of sub_char_table_set_contents.
3823 2012-08-18 Chong Yidong <cyd@gnu.org>
3825 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE

3996 directly-specified attributes.
3997 (merge_face_ref): Recognize :font.
3999 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>

4046 Use C-locale tests instead of locale-specific tests for character
4047 types, since we want the ASCII interpretation here, not the
4048 interpretation suitable for whatever happens to be the current locale.

4653 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
4654 * w32.c (init_environment): Change the default values of many
4655 environment variables in dflt_envvars[] to NULL, to avoid pushing
4656 them into environment when they were not already defined.
4657 Remove the code that deletes site-lisp subdirectories from the default
4658 value of EMACSLOADPATH, as it is no longer needed.
4659 (check_windows_init_file): Now external, not static.
4660 Use Vload_path as is, without adding anything, as this function is now
4661 called when Vload_path is already set up.
4663 * w32.h (check_windows_init_file): Add prototype.
4665 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
4666 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
4667 compatibility with Posix platforms.
4668 (main): Move the call to check_windows_init_file to here from
4670 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
4671 any, in the DEFALT argument into the root of the Emacs build or
4672 installation tree, as appropriate.
4674 * callproc.c (init_callproc_1): Call decode_env_path instead of
4675 doing its equivalent by hand.
4676 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
4677 the code that sets Vexec_path run on MS-Windows.
4679 * lread.c (init_lread): Add comments to #ifdef's.
4681 * msdos.c (dos_set_window_size, IT_update_begin)

4693 Remove unnecessary casts involving pointers.
4694 These casts are no longer needed now that we assume C89 or later,

4707 (x_get_window_property, x_get_window_property_as_lisp_data):
4708 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
4709 Remove unnecessary pointer casts.
4710 * alloc.c (record_xmalloc): New function.
4711 * lisp.h (record_xmalloc): New decl.
4712 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
4713 more like a function. This is because the pointer cast is not
4714 needed. All uses changed.
4715 * print.c (print_string, print_error_message): Avoid length recalc.
4717 Improve fix for macroexp crash with debugging (Bug#12118).
4718 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
4719 ARRAY_MARK_FLAG when checking subscripts, because ASET is
4720 not supposed to be invoked from the garbage collector.
4721 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
4722 (gc_aset): New function, which is like ASET but can be
4723 used in the garbage collector.
4724 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

4737 (map_w32_filename): Improve commentary. Simplify switch.
4738 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
4739 headers (most versions of MinGW w32api don't).
4740 (get_security_info, create_symbolic_link)
4741 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
4743 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
4744 in the argument file name.

4747 (sys_rename): Diagnose renaming of a symlink when the user doesn't
4748 have the required privileges.
4749 (get_file_security_desc_by_name): Rename from
4750 get_file_security_desc.

4752 with addition of handling of symlinks and support for 'lstat'.
4753 If possible, get file's attributes and security information by
4754 handle, not by name. Produce S_IFLNK bit for symlinks, when
4755 called from 'lstat'.
4756 (stat, lstat): New functions, call 'stat_worker'.
4757 (symlink, readlink, careadlinkat): Rewritten to create and resolve
4758 symlinks when the underlying filesystem supports them.
4760 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
4762 Fix macroexp crash on Windows with debugging (Bug#12118).
4763 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
4764 checking subscripts; problem introduced with the recent
4765 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
4766 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
4767 since it's used in non-static inline functions now.
4769 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
4770 Don't assume buffer size fits in 'int'. Remove unused local.
4772 Use C99-style 'extern inline' if available.

4787 * category.c (CATEGORY_INLINE):
4788 * character.c (CHARACTER_INLINE):
4789 * charset.c (CHARSET_INLINE):
4790 * composite.c (COMPOSITE_INLINE):
4791 * dispnew.c (DISPEXTERN_INLINE):
4792 * sysdep.c (SYSTIME_INLINE):
4793 Define to EXTERN_INLINE, so that the corresponding functions
4794 are compiled into code.
4795 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
4796 (INLINE_HEADER_END): New macros.
4797 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

4817 hard-coding the path separator.
4819 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
4821 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
4822 This how ASET and AREF are supposed to work, and makes
4823 it easier to think about future improvements. See
4824 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
4825 * charset.h (set_charset_attr): New function.

5079 does that unconditionally. Remove file, which is now empty.
5081 * s/freebsd.h, s/gnu-linux.h, s/sol2-6.h, s/unixware.h:
5084 2012-07-30 Paul Eggert <eggert@cs.ucla.edu>
5086 Export to GDB most of lisp.h's remaining object-like macros.

5202 * w32inevt.c: Include w32inevt.h.
5203 (w32_read_console_input): New inline function, calls either
5204 ReadConsoleInputA or ReadConsoleInputW, depending on the value of
5205 w32_console_unicode_input.
5206 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
5207 (w32_kbd_patch_key, key_event): Use the codepage returned by
5208 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.
5209 (key_event): use uChar.UnicodeChar only if
5210 w32_console_unicode_input is non-zero.

5237 * alloc.c (listn): Fix the order the arguments are consed onto the
5240 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
5241 enumeration constants, as PURE and HEAP are too general, and clash
5242 with other headers and sources, such as gmalloc.c and the
5243 MS-Windows system headers. All users changed.
5245 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
5247 Revert last save_excursion_save and save_excursion_restore changes.
5248 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

5258 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
5260 Improve GDB symbol export (Bug#12036).
5261 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
5262 arms of an 'if', not using conditional expressions; otherwise GDB
5263 complains about the types in the unevaluated arm when the argument
5264 is an integer literal.
5265 (xgetint): Simplify expression.
5266 * alloc.c (gdb_make_enums_visible): New constant. This ports to
5267 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
5268 Zaretskii in <http://bugs.gnu.org/12036#13>.
5269 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
5270 needed now that we have gdb_make_enums_visible.
5271 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
5272 (enum enum_USE_LSB_TAG):
5273 New enum types, packaging up enums that need to be exported to GDB.
5275 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>

5291 * xdisp.c (syms_of_xdisp): Likewise.
5292 * xfns.c (syms_of_xfns): Likewise.
5294 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
5296 Fast save_excursion_save and save_excursion_restore.
5297 * lisp.h (struct Lisp_Excursion): New data type.
5298 (PVEC_EXCURSION): New pseudovector type.
5299 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
5300 to deal with it. Adjust comments.

5311 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
5313 Fix export of symbols to GDB (Bug#12036).
5314 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
5315 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
5316 emacs.c, as this is a more-suitable home. Had this been done earlier
5317 the fix for 12036 would have avoided some of the problems noted in
5318 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
5319 would have been more obvious.
5320 * emacs.c: Do not include <verify.h>; no longer needed.
5321 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
5322 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
5323 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
5324 Remove; now done in lisp.h.
5325 * lisp.h (PUBLISH_TO_GDB): New macro.

5327 (DATA_SEG_BITS): Use it.
5328 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
5329 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
5330 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
5331 not be usable in #if. This simplifies things.
5333 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
5335 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
5337 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
5339 Simplify export of symbols to GDB (Bug#12036).
5340 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
5341 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
5342 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
5343 Adjust to changes in lisp.h and emacs.c, by using
5344 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
5345 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
5346 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
5347 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
5348 instead of gdb_valbits.
5349 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
5350 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
5351 instead of gdb_array_mark_flag.
5352 (xboolvector): Get size from $->size, not $->header.size.
5353 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
5354 (xreload, hook-run, hookpost-run): Remove.
5355 * emacs.c: Include <verify.h>.
5356 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
5357 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
5359 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
5360 (gdb_USE_LSB_TAG): New enum constants.
5361 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
5362 Also define these as enum constants, so they're visible to GDB.
5363 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
5364 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
5365 as constants, so they're visible to GDB.
5366 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
5367 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
5368 Now enum constants, not macros, so they're visible to GDB.
5369 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
5370 more convenient now. All uses changed.
5371 (VALMASK) [USE_LSB_TAG]: Also define in this case.
5372 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
5374 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
5376 Explicitly free restriction data that are not needed anymore.
5377 * editfns.c (save_restriction_restore): Free restriction data.
5379 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
5381 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
5382 add argument, tune behavior, and adjust all callers.
5384 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
5386 Use typedef for EMACS_INT, EMACS_UINT.
5387 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
5388 than macros. This simplifies debugging in the usual case, since
5389 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
5390 and it allows expressions involving EMACS_INT casts.
5391 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
5393 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
5395 * nsterm.m (ns_read_socket): Return early if there is a modal
5398 2012-07-25 Martin Rudalics <rudalics@gmx.at>
5400 * frame.c (Fredirect_frame_focus): In doc-string don't mention
5401 that FOCUS-FRAME can be omitted.
5403 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
5405 Adjust buffer text indirection counters at the end of Fkill_buffer.
5406 * buffer.c (Fkill_buffer): Adjust indirection counters when the
5407 buffer is definitely dead. This should really fix an issue reported
5408 by Christoph Scholtes again. (Bug#12007).
5409 (init_buffer_once): Initialize indirection counters of
5410 buffer_defaults and buffer_local_symbols (for sanity and safety).
5412 2012-07-24 Eli Zaretskii <eliz@gnu.org>
5414 * xdisp.c (init_iterator): Don't compute dimensions of truncation

6254 Prefer snprintf to strncpy.
6255 * nsterm.m (ns_term_init):
6256 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
6257 * nsterm.m (ns_term_init):
6258 Avoid the need for strncpy, by using build_string or
6259 make_unibyte_string directly. Use dtoastr, not snprintf.
6260 * process.c (Fmake_network_process): Diagnose service names that
6261 are too long, rather than silently truncating them or creating

6322 2012-07-10 Glenn Morris <rgm@gnu.org>
6324 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
6325 Move PENDING_OUTPUT_COUNT definition to configure.
6327 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
6328 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
6329 * s/gnu.h (DATA_START): Move definitions to configure.
6331 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
6332 We include usg5-4-common.h, which defines them both.
6334 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
6335 O_RDONLY already includes it).
6337 Stop ns builds setting the EMACSLOADPATH environment variable.
6338 * nsterm.m (ns_load_path): Rename from ns_init_paths.
6339 Now it does not set EMACSLOADPATH, just returns the load-path string.
6340 * nsterm.h: Update accordingly.
6341 * lread.c [HAVE_NS]: Include nsterm.h.
6342 (init_lread) [HAVE_NS]: Use ns_load_path.

6345 2012-07-09 Glenn Morris <rgm@gnu.org>
6347 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
6348 since the included bsd-common.h does so.
6350 Stop ns builds setting the EMACSPATH environment variable.
6351 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
6352 (ns_init_paths): Do not set EMACSPATH.
6353 * nsterm.h (ns_exec_path): Add it.
6354 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
6357 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
6359 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
6361 * process.c (wait_reading_process_output): 'waitchannels' was unset
6362 when read_kbd || !NILP (wait_for_cell); fix this.
6364 Add GCC-style 'const' attribute to functions that can use it.
6365 * character.h (char_resolve_modifier_mask):
6366 * keyboard.h (make_ctrl_char):
6367 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
6368 (init_character_once, next_almost_prime, init_fns, init_image)
6369 (flush_pending_output, init_sound):

6374 Declare the dummy function with ATTRIBUTE_CONST.
6375 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
6376 Add decls with ATTRIBUTE_CONST.
6378 Minor improvements to make_formatted_string.
6379 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
6380 where int is good enough, as vsprintf returns an int.
6381 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
6383 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
6385 Use make_formatted_string to avoid double length calculation.
6386 * lisp.h (make_formatted_string): New prototype.
6387 * alloc.c (make_formatted_string): New function.
6388 * buffer.c (Fgenerate_new_buffer_name): Use it.
6389 * dbusbind.c (syms_of_dbusbind): Likewise.
6390 * editfns.c (Fcurrent_time_zone): Likewise.
6391 * filelock.c (get_boot_time): Likewise.
6392 * frame.c (make_terminal_frame, set_term_frame_name)
6393 (x_report_frame_params): Likewise.
6394 * image.c (gs_load): Likewise.
6395 * minibuf.c (get_minibuffer): Likewise.

6406 * nsterm.h (ns_etc_directory): Add it.
6407 * callproc.c [HAVE_NS]: Include nsterm.h.
6408 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
6410 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
6412 Move marker debugging code under MARKER_DEBUG.
6413 * marker.c (MARKER_DEBUG): Move marker debugging code under
6414 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
6415 for bootstrap with --enable-checking (~3x slowdown reported
6416 by Juanma Barranquero <lekktu@gmail.com>).
6417 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
6419 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
6421 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
6422 See <http://bugs.gnu.org/11825#29>.
6424 2012-07-08 Eli Zaretskii <eliz@gnu.org>
6426 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
6427 has no font, use the frame's font. (Bug#11813)
6428 (display_line): Add commentary about displaying truncation glyphs
6430 (produce_special_glyphs): Move here from term.c.
6432 * term.c (produce_special_glyphs): Move to xdisp.c.
6434 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
6437 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
6439 * xdisp.c (display_line): Avoid warning about implicit declaration
6442 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
6444 * lisp.h: Remove empty conditional.
6446 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
6448 * lread.c (load_path_check): Now static.
6450 Fix some minor --with-ns problems found by static checking.
6451 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
6452 (x_set_font) [!HAVE_X_WINDOWS]:
6453 * image.c (xpm_load_image) [HAVE_NS]:
6454 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
6455 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
6456 Remove unused local.
6457 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
6458 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
6459 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
6460 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
6461 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
6462 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
6463 Fix pointer signedness problem.
6464 * xfaces.c (FRAME_X_FONT_TABLE):
6465 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
6467 2012-07-07 Glenn Morris <rgm@gnu.org>
6469 * lread.c (load_path_check): New function, split from init_lread.
6470 (init_lread): Reorganize. Motivation:
6471 If EMACSLOADPATH is set, check/warn about that rather than the
6472 defaults, which we are not going to use. Hence we can remove
6473 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
6474 Don't warn if site-lisp directories are missing.
6475 If not installed, start from a blank load-path, since
6476 PATH_LOADSEARCH refers to the eventual installation directories.
6478 2012-07-07 Eli Zaretskii <eliz@gnu.org>
6480 Support truncation and continuation glyphs on GUI frames, when
6481 fringes are disabled. (Bug#11832)
6482 * xdisp.c (init_iterator): Get dimensions of truncation and
6483 continuation glyphs even if on GUI frames.
6484 Adjust it->last_visible_x on GUI frames when the left or right fringes,
6485 or both, are absent.
6486 (start_display, move_it_in_display_line_to): Handle the case of a
6487 GUI frame without a fringe to display continuation or truncation
6489 (insert_left_trunc_glyphs): Support GUI frames: make sure
6490 truncation glyphs overwrite enough glyphs from the current line to
6491 have sufficient space in pixels.
6492 (display_line): Support truncation and continuation glyphs on GUI
6493 frames. If some spare pixels are left on the line after inserting
6494 the truncation glyphs, fill that space with a stretch glyph of a
6495 suitably computed width.
6497 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
6498 produce_glyphs, to support GUI sessions.
6500 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
6502 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
6504 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
6506 Do not require float-time's arg to fit in time_t (Bug#11825).
6507 This works better on hosts where time_t is unsigned, and where
6508 float-time is applied to the (negative) difference between two times.
6509 * editfns.c (decode_time_components): Last arg is now double *,
6510 not int *, and means to store all the result as a double, without
6511 worrying about whether the seconds part fits in time_t.
6512 All callers changed.
6513 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
6514 All callers changed.
6515 (Ffloat_time): Do not fail merely because the specified time falls
6516 outside of time_t range.
6518 2012-07-07 Glenn Morris <rgm@gnu.org>
6520 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

6531 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6533 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

6535 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
6536 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
6537 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
6538 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
6540 * xfont.c (compare_font_names): Redo to omit the need for casts.
6542 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
6544 * xfns.c (Fx_change_window_property): Doc fix.
6545 * w32fns.c (Fx_change_window_property): Doc fix.
6547 * w32fns.c (Fx_window_property): Accept the same arguments as the
6548 X Windows version. Doc fix.
6549 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
6551 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
6552 Eli Zaretskii <eliz@gnu.org>
6554 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
6555 Windows-specific code from nt/config.nt moved here.
6556 Obsolete settings removed.
6558 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6560 * process.c: Avoid unnecessary calls to gettime.
6561 (wait_reading_process_output): Don't get the time of day
6562 when gobbling data immediately and not waiting, as there's no need
6563 for it in that case. This removes a FIXME.
6565 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
6567 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
6568 is defined (Bug#11768).
6570 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6572 Fix marker debugging code.
6573 * marker.c (byte_char_debug_check): Do not perform the check
6574 if buffer is not multibyte.
6575 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
6576 Call byte_char_debug_check with correct arguments.
6578 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6580 Compile marker debugging code only if ENABLE_CHECKING is defined.
6581 * marker.c (byte_char_debug_check, count_markers):
6582 Use only if ENABLE_CHECKING is defined.
6583 (byte_debug_flag): Remove.
6584 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
6585 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
6587 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6589 Avoid code repetition in marker-related functions.
6590 * marker.c (attach_marker): New function.
6591 (Fset_marker, set_marker_restricted, set_marker_both)
6592 (set_marker_restricted_both): Use it.
6593 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
6594 Consistently rename charno to charpos.
6595 (marker_position): Add eassert.
6596 (marker_byte_position): Convert to eassert.

6615 * window.c (save_window_save): Likewise.
6617 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6619 Do not use Fdelete_overlay in delete_all_overlays
6620 to avoid redundant calls to unchain_overlay.
6621 * buffer.c (drop_overlay): New function.
6622 (delete_all_overlays, Fdelete_overlay): Use it.
6623 * minibuf.c (get_minibuffer): Fix comment.
6625 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6627 Port to OpenBSD 5.1 amd64.
6628 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
6629 This is needed for OpenBSD, and should be harmless on all BSD systems.
6630 Also, include <sys/sysctl.h>, as it should be available on all
6631 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
6632 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
6633 use p_pid member, not kp_proc.pid.
6635 2012-07-06 Glenn Morris <rgm@gnu.org>
6637 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
6639 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
6641 More xmalloc and related cleanup.

6650 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
6652 Omit needless casts involving void * pointers and allocation.
6653 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
6654 as the former is more robust if P's type is changed.
6655 Prefer xzalloc to xmalloc + memset 0.
6656 Simplify malloc-or-realloc to realloc.
6657 Don't worry about xmalloc returning a null pointer.
6658 Prefer xstrdup to xmalloc + strcpy.
6659 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
6661 * keyboard.c (apply_modifiers_uncached): Prefer local array to
6662 alloca of a constant.
6664 2012-07-05 Eli Zaretskii <eliz@gnu.org>
6666 * xdisp.c (display_line): Fix horizontal pixel coordinates when
6667 hscroll is larger than the line width. Fixes long and futile
6668 looping inside extend_face_to_end_of_line (on a TTY) producing
6669 glyphs that are not needed and thrown away.
6671 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
6673 * marker.c (set_marker_restricted_both): Simplify by using

6699 * xdisp.c (window_hscroll_limited): New function.
6700 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
6701 coordinates when window's hscroll is set to insanely large
6704 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
6706 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

6773 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
6774 This should be fixed in a better way; see Eli Zaretskii in
6775 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
6776 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
6778 * fileio.c (time_error_value): Rename from special_mtime.
6779 The old name's problems were noted by Eli Zaretskii in
6780 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
6782 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
6783 This variable's comment says Emacs needs at least one GDB-visible
6784 symbol of type enum pvec_type, to work around GDB problems.
6785 The symbol's value doesn't matter.
6787 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
6788 that causes compilation to fail on pre-C99 compilers.
6790 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
6792 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
6793 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
6795 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6797 * buffer.c (init_buffer_once): Fix initialization of
6798 headers for buffer_defaults and buffer_local_symbols.
6799 Reported by Juanma Barranquero <lekktu@gmail.com>.
6801 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
6803 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
6804 * lisp.h (enum pvec_type): Use fewer bits.
6805 (PSEUDOVECTOR_SIZE_BITS): New constant.
6806 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
6807 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
6808 change in pvec_type.
6809 (PSEUDOVECTOR_TYPEP): New macro.
6810 (TYPED_PSEUDOVECTORP): Use it.
6811 * fns.c (internal_equal): Adapt code to extract pvectype.
6812 * emacs.c (gdb_pvec_type): Update type.
6813 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
6814 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
6815 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
6816 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
6817 (sweep_vectors): Use it. Use local var `total_bytes' instead of
6818 abusing vector->header.next.nbytes.
6819 (live_vector_p): Use PVEC_TYPE.
6820 (mark_object): Adapt code to extract pvectype. Use switch.
6822 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6824 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
6825 Tighten new eassert a bit.
6827 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6829 Fix compilation with --enable-gcc-warnings and -O1
6831 * doprnt.c (doprnt): Change type of tem to int, initialize
6832 to avoid compiler warning. Add eassert.
6833 * search.c (simple_search): Initialize match_byte to avoid
6834 compiler warning. Add eassert.
6836 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6838 Avoid weird behavior with large horizontal scrolls.
6839 Without this change, for example, large hscroll values would
6840 mess up Emacs's display on Fedora 15 x86, presumably due to
6841 overflows in int calculations in the display code.
6842 Also, if buffers had long lines, Emacs would freeze.
6843 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
6844 (set_window_hscroll): New function, containing the old guts of
6845 Fset_window_hscroll. Return the clipped value.
6846 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
6847 This avoids the need to check against PTRDIFF_MAX.
6849 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
6851 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6853 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
6855 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6857 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
6858 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
6859 since GCC 4.4.6 issues a bogus warning for them.
6861 Fix bugs in file timestamp newness comparisons.
6862 * fileio.c (Ffile_newer_than_file_p):
6863 * lread.c (Fload): Use full timestamp resolution of files,
6864 not just the 1-second resolution, so that files that are only
6865 slightly newer still count as newer.
6866 * fileio.c (Ffile_newer_than_file_p): Don't assume file
6867 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
6869 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
6871 * fileio.c: Improve handling of file time marker. (Bug#11852)
6872 (special_mtime): New function.
6873 (Finsert_file_contents, Fverify_visited_file_modtime):
6874 Use it to set special mtime values consistently.
6876 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
6878 * fileio.c (Finsert_file_contents): Properly handle st_mtime
6879 marker for non-existing file. (Bug#11852)
6881 2012-07-03 Glenn Morris <rgm@gnu.org>
6883 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
6884 and did not make it into globals.h).
6886 2012-07-03 Tom Tromey <tromey@redhat.com>
6888 * window.c (Fset_window_margins, Fset_window_fringes)
6889 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
6890 * textprop.c (Fprevious_property_change): No longer static.
6891 * syntax.c (Fsyntax_table_p): No longer static.
6892 * process.c (Fget_process, Fprocess_datagram_address): No longer

6902 * doc.c (Fdocumentation_property, Fsnarf_documentation):
6904 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): No longer
6906 * dired.c (Ffile_attributes): No longer static.
6907 * composite.c (Fcomposition_get_gstring): No longer static.
6908 * callproc.c (Fgetenv_internal): No longer static.
6910 * ccl.h: Remove EXFUNs.
6911 * buffer.h: Remove EXFUNs.
6912 * dispextern.h: Remove EXFUNs.
6913 * intervals.h: Remove EXFUNs.
6914 * fontset.h: Remove EXFUN.
6915 * font.h: Remove EXFUNs.
6916 * dosfns.c (system_process_attributes): Remove EXFUN.
6917 * keymap.h: Remove EXFUNs.
6918 * lisp.h: Remove EXFUNs.
6919 * w32term.h: Remove EXFUNs.
6920 * window.h: Remove EXFUNs.
6921 * xsettings.h: Remove EXFUN.
6922 * xterm.h: Remove EXFUN.
6924 2012-07-03 Glenn Morris <rgm@gnu.org>
6926 * lisp.h (Frandom): Make it visible to C.
6927 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
6928 buffer for invisible buffers. (Bug#1229)
6930 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6932 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
6933 values which aren't power of 2.
6934 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
6935 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
6938 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
6940 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
6942 * alloc.c (mark_object): Revert part of last patch to use `switch'.
6944 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6946 * alloc.c (allocate_vector_block): Remove redundant
6947 calls to mallopt if DOUG_LEA_MALLOC is defined.
6948 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
6949 avoid calls to mallopt if zero_vector is returned.
6951 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6953 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
6954 is enabled, avoid dereferencing NULL current_sblock if
6957 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6959 Cleanup basic buffer management.
6960 * buffer.h (struct buffer): Change layout to use generic vector
6961 marking code. Fix some comments. Change type of 'clip_changed'
6962 to bitfield. Remove unused #ifndef old.
6963 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
6964 (GET_OVERLAYS_AT): Fix indentation.
6965 (for_each_per_buffer_object_at): New macro.
6966 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
6967 (Fbuffer_local_variables): Use it.
6968 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
6969 * alloc.c (allocate_buffer): Adjust to match new layout of
6970 struct buffer. Fix comment.
6971 (mark_overlay): New function.
6972 (mark_buffer): Use it. Use mark_vectorlike to mark normal
6973 Lisp area of struct buffer.
6974 (mark_object): Use it. Adjust marking of misc objects
6975 and related comments.
6977 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
6979 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
6980 wrapper that is not needed because the wrapped code is a no-op (zero
6981 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
6982 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
6984 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
6986 * alloc.c (mark_buffer): Simplify. Remove prototype.
6987 (mark_object): Add comment. Reorganize marking of vector-like
6988 objects. Use CHECK_LIVE for all vector-like objects except buffers
6989 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
6990 Avoid redundant calls to mark_vectorlike for bool vectors.
6992 2012-06-30 Glenn Morris <rgm@gnu.org>
6994 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
6996 * epaths.in (PATH_SITELOADSEARCH): New.
6997 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
6998 This is rather than relying on --enable-locallisppath elements
6999 having "site-lisp" in their names. (Bug#10208#25, 11658)
7001 2012-06-30 Eli Zaretskii <eliz@gnu.org>
7003 * w32proc.c (sys_select): Accept and ignore one more argument.
7005 * w32.c (emacs_gnutls_pull): Call select with one more argument.
7007 * sysselect.h [DOS_NT]: Don't include sys/select.h.
7008 (pselect) [!MS_DOS]: Redirect to sys_select.
7010 * sysdep.c: Don't include dos.h and dosfns.h.
7012 * process.c (sys_select):
7013 * msdos.c (sys_select): Accept one more argument and ignore it.
7015 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
7016 adapt data types and code to that.
7019 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
7020 which clashes with the gnulib function of the same name.
7022 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
7024 * font.c (font_style_to_value, font_style_symbolic)
7025 (font_prop_validate_style): Add type checks for values in
7028 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
7030 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
7033 2012-06-29 Eli Zaretskii <eliz@gnu.org>
7035 * xdisp.c (try_window_id): Undo last change.
7037 * w32.c (getwd): Adjust commentary about startup_dir.
7038 (init_environment): Always call sys_access, even in non-MSVC
7039 builds. Don't chdir to the directory of the Emacs executable.
7040 This undoes code from 1997 which was justified by the need to
7041 "avoid conflicts when removing and renaming directories". But its
7042 downside was that every relative file name was being interpreted
7043 relative to the directory of the Emacs executable, which can never
7044 be TRT. In particular, it broke sys_access when called with
7045 relative file names.
7046 (sys_access): Map GetLastError to errno.
7048 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
7050 * window.h (struct window): Change type of 'fringes_outside_margins'

7054 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
7057 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
7059 * gnutls.c (emacs_gnutls_handshake):
7060 Add QUIT to make the loop interruptible.
7062 2012-06-29 Glenn Morris <rgm@gnu.org>
7064 * charset.c (init_charset): Make lack of etc/charsets fatal.
7066 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
7068 * editfns.c (region_limit): Fix type mismatch.
7070 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
7072 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
7073 undefined. Convert from xassert to eassert.
7074 * nsmenu.m: Convert from xassert to eassert.
7075 * nsterm.m: Likewise.
7077 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
7079 * editfns.c (region_limit): Clip to narrowing (bug#11770).
7081 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
7083 Avoid integer overflow on scroll-left and scroll-right.
7084 * window.c (HSCROLL_MAX): New macro.
7085 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
7086 overflow when requested scroll falls outside ptrdiff_t range.
7088 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
7090 * window.h (struct window): Change type of 'hscroll',
7091 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
7092 'last_modified' and 'last_overlay_modified' to EMACS_INT.
7093 Adjust users accordingly.
7094 * xdisp.c (try_cursor_movement): Replace type check with eassert.
7095 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
7096 from EMACS_INT to ptrdiff_t.
7097 (make_window): Omit redundant initialization.
7099 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

7103 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
7105 * window.h (struct window): Change type of 'use_time' and
7106 'sequence_number' from Lisp_Object to int.

7116 Fix GLYPH_DEBUG usage assuming that it may be undefined,
7117 adjust comments accordingly.

7172 * alloc.c (allocate_string): Omit intervals initialization.
7173 * alloc.c (make_uninit_multibyte_string): Initialize intervals
7174 as in make_pure_string and make_pure_c_string.
7176 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
7178 * alloc.c (allocate_string): Fix last change.
7180 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

7230 * alloc.c: Remove build_string.
7231 * lisp.h: Define build_string as static inline. This provides
7232 a better opportunity to optimize away calls to strlen when the
7233 function is called with compile-time constant argument.
7234 * image.c (imagemagick_error): Convert to build_string.
7235 * w32proc.c (sys_spawnve): Likewise.

7238 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
7240 Use sprintf return value instead of invoking strlen on result.
7241 In the old days this wasn't portable, since some sprintf
7242 implementations returned char *. But they died out years ago and
7243 Emacs already assumes sprintf returns int.
7244 Similarly for float_to_string.
7245 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
7246 * ccl.c (ccl_driver):
7247 * character.c (string_escape_byte8):

7252 * xfns.c (syms_of_xfns):
7253 Use sprintf or float_to_string result to avoid need to call strlen.
7254 * data.c (Fnumber_to_string):
7255 Use make_unibyte_string, since the string must be ASCII.
7256 * lisp.h, print.c (float_to_string): Now returns int length.
7257 * term.c (produce_glyphless_glyph):
7258 Use sprintf result rather than recomputing it.
7260 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
7261 * Makefile.in (ALL_CFLAGS):
7262 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

7359 * keyboard.c (kbd_buffer_get_event):
7360 * process.c (Faccept_process_output):
7361 Use it to avoid bogus compiler warnings with obsolescent GCC versions.

7363 when time_t is unsigned and as wide as intmax_t.
7364 See <http://bugs.gnu.org/9000#51>.
7366 2012-06-23 Eli Zaretskii <eliz@gnu.org>

7429 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
7431 Support higher-resolution time stamps (Bug#9000).
7432 The time stamps are only nanosecond-resolution at the C level,
7433 since that's the best that any real-world system supports now.
7434 But they are picosecond-resolution at the Lisp level, as that's
7435 easy, and leaves room for future OS improvements.
7437 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
7440 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
7441 Don't get current time unless it's needed.
7443 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
7444 now provides it if it's absent.
7445 (start_atimer): Port to higher-res time stamps.
7446 Check for time stamp overflow. Don't get current time more
7447 often than is needed.
7449 * buffer.h (struct buffer): Buffer modtime now has high resolution.
7450 Include systime.h, not time.h.
7451 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
7453 * dired.c: Include stat-time.h.
7454 (Ffile-attributes): File times now have higher resolution.
7456 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
7457 (struct image): Timestamp now has higher resolution.
7459 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
7460 has at least microseconds now. All uses removed.
7461 (update_frame, update_single_window, update_window, update_frame_1)
7462 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
7463 (duration_to_sec_usec): Remove; no longer needed.
7465 * editfns.c (time_overflow): Now extern.
7466 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
7467 (float-time, Fformat_time_string, Fcurrent_time_string)
7468 (Fcurrent_time_zone): Accept and generate higher-resolution
7470 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
7471 (decode_time_components, lisp_seconds_argument): New functions.
7472 (make_time): Now static.
7473 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
7474 Report an error if the time is invalid, rather than having the caller
7477 * fileio.c: Include <stat-time.h>
7478 (Fcopy_file): Copy higher-resolution time stamps.
7479 Prefer to set the time stamp via a file descriptor if that works.
7480 (Fset_file_times, Finsert_file_contents, Fwrite_region)
7481 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
7482 (Fvisited_file_modtime, Fset_visited_file_modtime):
7483 Support higher-resolution time stamps.
7485 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
7487 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
7489 * image.c (prepare_image_for_display, clear_image_cache)
7490 (lookup_image): Port to higer-resolution time stamps.
7492 * keyboard.c (start_polling, bind_polling_period):
7493 Check for time stamp overflow.
7494 (read_char, kbd_buffer_get_event, timer_start_idle)
7495 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
7496 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
7497 Port to higher-resolution time stamps. Do not assume time_t is signed.
7498 (decode_timer): New function. Timers are now vectors of length 9,
7499 not 8, to accommodate the picosecond component.
7500 (timer_check_2): Use it.
7502 * nsterm.m (select_timeout, timeval_subtract): Remove.
7503 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
7504 as they're a bit more accurate and handle overflow better.
7505 (ns_select): Change prototype to be compatible with pselect.
7506 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
7507 * nsterm.h (ns_select): Adjust prototype.
7509 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
7510 us-resolution time stamps.
7511 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
7513 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
7515 * lisp.h (time_overflow): New decl.
7516 (wait_reading_process_output): First arg is now intmax_t, not int,
7517 to accommodate larger waits.
7519 * process.h (struct Lisp_Process.read_output_delay):
7520 Now counts nanoseconds, not microseconds.
7521 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
7523 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
7524 (wait_reading_process_output):
7525 Port to ns-resolution time stamps.
7526 (Faccept_process_output, wait_reading_process_output):
7527 Check for time stamp overflow. Do not assume time_t is signed.
7528 (select_wrapper): Remove; we now use pselect.
7529 (Fprocess_attributes): Now generates ns-resolution time stamps.
7531 * sysdep.c: Include utimens.h. Don't include utime.h
7532 or worry about struct utimbuf; gnulib does that for us now.
7533 (gettimeofday): Remove; gnulib provides a substitute.
7534 (make_timeval): New function.
7535 (set_file_times): Now sets ns-resolution time stamps.
7536 New arg FD; all uses changed.
7537 (time_from_jiffies, ltime_from_jiffies, get_up_time)
7538 (system_process_attributes):
7539 Now returns ns-resolution time stamp. All uses changed.
7540 Check for time stamp overflow.
7542 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
7543 provides a substitute now.
7545 * systime.h: Include timespec.h rather than sys/time.h and time.h,
7546 since it guarantees struct timespec.
7547 (EMACS_TIME): Now struct timespec, so that we can support
7548 ns-resolution time stamps.
7549 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
7550 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
7551 (EMACS_USECS): Remove.
7552 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
7553 so multiply the arg by 1000 before storing it.
7554 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
7556 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
7557 Port to ns-resolution time stamps.
7558 (EMACS_TIME_NEG_P): Remove; replaced by....
7559 (EMACS_TIME_SIGN): New macro.
7560 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
7561 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
7562 (set_file_times, make_time, lisp_time_argument): Adjust signature.
7563 (make_timeval, make_lisp_time, decode_time_components): New decls.
7564 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
7565 that it mishandled time_t overflow. You can't compare by subtracting!
7566 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
7567 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
7569 * term.c: Include <sys/time.h>.
7570 (timeval_to_Time): New function, for proper overflow wraparound.

7575 (Fprimitive_undo): Use them when restoring time stamps.
7577 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
7578 (w32_get_internal_run_time):
7579 Port to higher-resolution Emacs time stamps.
7580 (ltime): Now accepts single 64-bit integer, as that's more convenient
7583 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
7585 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
7586 for compatibility with pselect. Support ns-resolution time stamps.
7588 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
7590 * xselect.c (wait_for_property_change, x_get_foreign_selection):
7591 Check for time stamp overflow, and support ns-resolution time stamps.
7593 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
7594 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
7595 (timeval_subtract): Remove; no longer needed.
7596 (XTflash, XTring_bell, x_wait_for_event):
7597 Port to ns-resolution time stamps. Don't assume time_t is signed.
7599 2012-06-22 Chong Yidong <cyd@gnu.org>

7603 2012-06-22 Eli Zaretskii <eliz@gnu.org>
7605 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
7606 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
7607 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
7608 staticidx goes up to 1597 out of 1600 = 0x640.)
7610 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
7612 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
7613 Otherwise, the umask might be mistakenly 0 while handling input signals.

7634 (unwind_format_mode_line): Restore them.
7635 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
7637 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
7638 since tty frames can be explicitly named.
7639 (prepare_menu_bars): Likewise.
7641 * term.c (Ftty_top_frame): New function.
7643 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

7646 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
7647 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
7648 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
7649 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
7650 (METER_1, METER_2): Simplify.
7652 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
7654 * data.c (Fdefalias): Return `symbol' (bug#11686).
7656 2012-06-18 Martin Rudalics <rudalics@gmx.at>
7658 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
7659 gets killed during executing of this function (Bug#11665).
7660 Try to always return Qt when the buffer has been actually killed.
7661 (Vkill_buffer_query_functions): In doc-string say that functions
7662 run by this hook should not change the current buffer.
7664 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
7666 Fix recently-introduced process.c problems found by static checking.
7667 * process.c (write_queue_push, write_queue_pop, send_process):

7684 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
7686 * lisp.h (eassert): Assume C89 or later.
7687 This removes the need for CHECK.
7688 (CHECK): Remove. Its comments about always evaluating its
7689 argument were confusing, as 'eassert' typically does not evaluate
7692 * coding.c (produce_chars): Use ptrdiff_t, not int.
7694 * xterm.c (x_draw_underwave): Check for integer overflow.
7695 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

7788 * xdisp.c (set_cursor_from_row): Don't dereference glyphs_end.
7789 If all the glyphs of the glyph row came from strings, and we have no
7790 cursor positioning clues, put the cursor on the first glyph of the

7793 indexing into it->string_overlays array. (Bug#11653)
7794 (set_cursor_from_row): Use the leftmost glyph as GLYPH_BEFORE, not
7795 the rightmost. (Bug#11720)

7807 info of the initial frame. (Bug#11677)
7809 2012-06-14 Paul Eggert <eggert@cs.ucla.edu>

7817 (LISP_INT_TAG, case_Lisp_Int, LISP_STRING_TAG, LISP_INT_TAG_P)
7818 (LISP_INT1_TAG, enum Lisp_Type, XINT, XUINT, make_number):

7847 * frame.c (delete_frame): Remove outdated comment.
7848 * w32fns.c (Fw32_register_hot_key): Use XLI instead of checking
7849 USE_LISP_UNION_TYPE.

7868 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
7869 * alloc.c (make_number) [!defined make_number]:

7879 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
7880 code works fine either way, and efficiency is not a concern here,
7881 as the union type is for debugging, not for production.
7882 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
7883 Use an inline function on all platforms when using the union type,
7884 since this is simpler and 'static inline' can be used portably
7886 (LISP_INITIALLY_ZERO): New macro.
7887 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
7888 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

7957 dbus_type_is_basic if available.
7958 (xd_extract_signed, xd_extract_unsigned): Rename from
7959 extract_signed and extract_unsigned, respectively. Adapt callers.

7970 * xdisp.c (vmessage): Treat frame message as multibyte.
7971 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
7972 would generate the diagnostic "Making \302\247 buffer-local while

7991 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
7993 2012-06-08 Eli Zaretskii <eliz@gnu.org>
7995 * alloc.c (allocate_vectorlike): Fix last change.
7997 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
7999 Block-based vector allocation of small vectors.
8000 * lisp.h (struct vectorlike_header): New field `nbytes',
8001 adjust comment accordingly.
8002 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'

8026 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
8028 * doprnt.c (doprnt): Truncate multibyte char correctly.
8029 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
8030 would mishandle a string argument "Xc" if X was a multibyte
8031 character of length 2: it would truncate after X's first byte
8032 rather than including all of X.
8034 2012-06-06 Chong Yidong <cyd@gnu.org>
8036 * buffer.c (word_wrap): Doc fix.

8085 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
8086 Convert pctcpu and pctmem to Lisp float properly.
8087 Let the compiler fold better, as 100.0/0x8000 is exact.
8089 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
8091 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
8094 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>

8098 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
8100 For a 'struct window', replace some Lisp_Object fields to
8101 bitfields where appropriate, remove unused fields.
8102 * window.h (struct window): Remove unused 'last_mark_x' and
8103 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
8104 change its type from Lisp_Object to bitfield.
8105 Change type of 'force_start', 'optional_new_start',
8106 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
8107 fields from Lisp_Object to bitfield. Adjust users accordingly.

8113 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:

8115 and 'double' in a couple of places.
8117 2012-05-31 Eli Zaretskii <eliz@gnu.org>
8119 * xdisp.c (handle_stop): Detect whether we have overlay strings
8120 loaded by testing it->current.overlay_string_index to be
8121 non-negative, instead of checking whether n_overlay_strings is
8122 positive. (Bug#11587)
8124 2012-05-31 Chong Yidong <cyd@gnu.org>
8126 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

8132 * search.c (search_buffer): Remove calls to
8133 r_alloc_inhibit_buffer_relocation, as it is now called by
8134 maybe_unify_char, which was the cause of relocation of buffer text
8137 2012-05-31 Eli Zaretskii <eliz@gnu.org>
8139 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
8140 for the duration of call to load_charset, to avoid problems with
8141 callers of maybe_unify_char that access buffer text through C
8144 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
8145 decrement the inhibition flag, instead of just setting or
8148 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
8150 Remove obsolete '#define static' cruft.
8151 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
8152 This #undef was "temporary" in 2000; it is no longer needed
8153 now that '#define static' has gone away.
8154 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
8155 (gray_bitmap_bits): Remove; no longer needed.
8156 All uses replaced with definiens.
8157 * xterm.c: Include "bitmaps/gray.xbm".

8168 (safe_bcopy): Remove decl; no longer has that name.
8169 (main): Coalesce #if into single bit of code, for simplicity.
8170 Cast pointers to uintptr_t, since standard libraries want integers

8199 Do not create empty overlays with the evaporate property (Bug#9642).
8200 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
8201 Bug#9642, but explicitly check that the buffer the overlay would
8202 be moved to is live and rearrange lines to make sure that errors
8203 will not put the overlay in an inconsistent state.
8204 (Fdelete_overlay): Cosmetics.
8206 2012-05-28 Eli Zaretskii <eliz@gnu.org>
8208 * w32term.c (my_bring_window_to_top): New function.
8209 (x_raise_frame): Use handle returned by DeferWindowPos, which

8223 This avoids undefined behavior that might cause the eassert
8224 to not catch an out-of-range value.
8226 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
8228 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

8238 when referring to sectname field in printf format.
8240 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
8242 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
8243 Only r_alloc_inhibit_buffer_relocation needed to be added;
8244 the others were already declared.
8246 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
8247 before checking whether it's out of range. Put the check inside
8249 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
8251 2012-05-27 Ken Brown <kbrown@cornell.edu>
8253 * callproc.c (Fcall_process): Restore a line that was accidentally
8254 commented out in the 2011-02-13 change (bug#11547).
8256 2012-05-27 Eli Zaretskii <eliz@gnu.org>
8258 * lisp.h [REL_ALLOC]: Add prototypes for external functions
8259 defined on ralloc.c.
8261 * buffer.c [REL_ALLOC]: Remove prototypes of
8262 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
8263 they are now on lisp.h.
8265 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
8267 * search.c (search_buffer): Use it to inhibit relocation of buffer
8268 text while re_search_2 is doing its job, because re_search_2 is
8269 passed C pointers to buffer text. (Bug#11519)
8271 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
8274 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
8275 state after an additional call to move_it_in_display_line_to, keep
8276 the values of it->max_ascent and it->max_descent found for the
8278 (pos_visible_p): Revert the comparison against bottom_y to what it
8279 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
8282 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
8284 Fix coding-related core dumps with gcc -ftrapv.
8285 The code was computing A - B, where A and B are pointers, and B is
8286 random garbage. This can lead to core dumps on platforms that
8287 have special pointer registers, and it also leads to core dumps on
8288 x86-64 when compiled with gcc -ftrapv. The fix is to compute
8289 A - B only when B is initialized properly.
8290 * coding.c (coding_set_source, coding_set_destination): Return void.
8291 (coding_change_source, coding_change_destinations): New functions,
8292 with the old behaviors of coding_set_source and coding_set_destination.
8293 All callers that need an offset changed to use these new functions.
8295 2012-05-26 Glenn Morris <rgm@gnu.org>
8297 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
8299 2012-05-26 Eli Zaretskii <eliz@gnu.org>
8301 Extend mouse support on W32 text-mode console.
8302 * xdisp.c (draw_row_with_mouse_face):
8303 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
8305 * w32console.c: Include window.h.
8306 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
8308 (initialize_w32_display): Initialize mouse-highlight data.
8310 * w32inevt.c: Include termchar.h and window.h.
8311 (do_mouse_event): Support mouse-autoselect-window. When the mouse
8312 moves, call note_mouse_highlight. If help_echo changed, call
8313 gen_help_event to produce help-echo message in the echo area.
8314 Call clear_mouse_face if mouse_face_hidden is set in the mouse
8317 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
8319 * lread.c (read1): Simplify slightly to avoid an overflow warning
8320 with GCC 4.7.0 on x86-64.
8322 2012-05-26 Eli Zaretskii <eliz@gnu.org>
8324 * bidi.c (bidi_mirror_char): Revert last change: an int is
8325 definitely wide enough here.
8327 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
8329 Fix integer width and related bugs (Bug#9874).

8340 (allocate_pseudovector):
8341 Use int, not EMACS_INT, where int is wide enough.
8342 (inhibit_garbage_collection, Fgarbage_collect):
8343 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

8361 (Foverlay_recenter, last_overlay_modification_hooks_used)
8362 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
8363 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8364 (validate_region): Omit unnecessary test for b <= e,
8365 since that's guaranteed by the previous test.
8366 (adjust_overlays_for_delete): Avoid pos + length overflow.
8367 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
8368 (report_overlay_modification):
8369 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
8370 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):

8372 after the EMACS_INT -> ptrdiff_t change.

8374 * buffer.h: Adjust decls to match defn changes elsewhere.

8379 not int, to avoid needless 32-bit limit on 64-bit hosts.
8380 (exec_byte_code): Use tighter memory-full test, one that checks
8381 for alloca overflow. Don't compute the address of the object just
8382 before an array, as that's not portable. Use EMACS_INT, not
8383 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
8384 * callint.c (Fcall_interactively):
8385 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

8397 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8398 (casify_object): Avoid integer overflow when overallocating buffer.
8399 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
8400 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
8401 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
8402 * category.h (CATEGORYP): Don't assume arg is nonnegative.
8403 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
8404 integers are now checked earlier. All uses replaced with XINT.
8406 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8407 For CCL_MapSingle, check that content and value are in int range.
8408 (ccl_driver, Fregister_code_conversion_map):
8409 Check that Vcode_version_map_vector is a vector.
8410 (resolve_symbol_ccl_program): Check that vector header is in range.
8411 Always copy the vector, so that we can check its contents reliably
8412 now rather than having to recheck each instruction as it's being
8413 executed. Check that vector words fit in 'int'.
8414 (ccl_get_compiled_code, Fregister_ccl_program)
8415 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
8416 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
8417 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
8418 contents are in range.
8419 (Fccl_execute_on_string): Check that status is in range.
8420 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
8421 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
8422 Accept and return EMACS_INT, not int, because callers can pass values

8428 (string_escape_byte8, Fget_byte):
8429 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8430 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
8431 avoid mishandling large integers.
8432 * character.h: Adjust decls to match defn changes elsewhere.

8441 (Fdefine_charset_internal): Check ranges here, more carefully.
8442 Don't rely on undefined behavior with signed left shift overflow.
8443 Don't assume unsigned int fits into fixnum, or that fixnum fits
8444 into unsigned int. Don't require max_code to be a valid fixnum;
8445 that's not true for gb10830 4-byte on a 32-bit host. Allow
8446 invalid_code to be a cons, for the same reason. Require code_offset
8447 to be a character. Avoid int overflow if max_char is close
8449 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
8450 this is intended anyway and avoids some undefined behavior.
8451 (load_charset_map): Pass unsigned, not int, as 2nd arg of
8452 INDEX_TO_CODE_POINT, as that's what it expects.
8453 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
8454 * charset.h (DECODE_CHAR): Return int, not unsigned;
8455 this is what was intended anyway, and it avoids undefined behavior.
8456 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
8457 integer-overflow issues.
8458 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
8459 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
8460 where the argument is EMACS_INT, and this behavior is not intended.
8461 * chartab.c (Fmake_char_table, Fset_char_table_range)
8462 (uniprop_get_decoder, uniprop_get_encoder):
8463 Don't assume fixnum fits in int.
8464 * cmds.c (move_point): New function, that does the gist of
8465 Fforward_char and Fbackward_char, but does so while checking
8466 for integer overflow more accurately.
8467 (Fforward_char, Fbackward_char): Use it.
8468 (Fforward_line, Fend_of_line, internal_self_insert)
8469 (internal_self_insert):
8470 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

9269 already have overlays loaded.
9270 (handle_single_display_spec): Before returning without displaying
9271 fringe bitmap, synchronize the bidi iterator with the main display
9272 iterator, by calling iterate_out_of_display_property.

9274 testing that it->string is a Lisp string.
9275 (get_next_display_element): When the current object is exhausted,

9279 proceed to consider_string_end without incrementing string
9280 position. Don't increment display vector index past the end of
9281 the display vector. (Bug#11417)
9282 (pos_visible_p): Don't report a position visible when move_it_to
9283 stopped at the last line of window, which happens to be scanned
9284 backwards by the bidi iteration. (Bug#11464)
9286 2012-05-14 Eli Zaretskii <eliz@gnu.org>
9288 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
9289 and right-margin display specs even if the spec is invalid or we
9290 are on a TTY, and thus unable to display on the fringes.
9291 That's because the text with the property will not be displayed anyway,
9292 so we need to signal to the caller that this is a "replacing"
9293 display spec. This fixes display when the spec is invalid or we
9296 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
9298 * unexaix.c (make_hdr): Fix typo in prototype.

9352 Untag more efficiently if USE_LSB_TAG.
9353 This is based on a proposal by YAMAMOTO Mitsuharu in
9354 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
9355 For an admittedly artificial (nth 8000 longlist) benchmark on
9356 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
9357 Emacs's overall text size by 1%.
9358 * lisp.h (XUNTAG): New macro.
9359 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
9360 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
9361 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
9362 * eval.c (Fautoload):
9363 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
9364 * frame.h (XFRAME): Use XUNTAG.
9366 Port recent dbusbind.c changes to 32-bit --with-wide-int.
9367 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
9368 Remove unportable assumptions about print widths of types like
9370 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
9371 intptr_t when converting between pointer and integer, to avoid GCC
9372 warnings about wrong width.
9374 2012-05-09 Eli Zaretskii <eliz@gnu.org>
9376 * w32proc.c (new_child): Force Windows to reserve only 64KB of
9377 stack for each reader_thread, instead of defaulting to 8MB
9378 determined by the linker. This avoids failures in creating
9379 subprocesses on Windows 7, see the discussion in this thread:
9380 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
9382 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
9384 Fix up display of the *Minibuf-0* buffer in the mini window.
9385 * keyboard.c (read_char): Don't clear the echo area if there's no
9387 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
9388 contents of *Minibuf-0*) if there's no message displayed in its stead.
9390 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
9392 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
9395 2012-05-06 Chong Yidong <cyd@gnu.org>
9397 * lisp.mk (lisp): Update.
9399 2012-05-05 Jim Meyering <meyering@redhat.com>
9401 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
9403 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
9405 * data.c (PUT_ERROR): New macro.
9406 (syms_of_data): Use it. Add new error type `user-error'.
9407 * undo.c (user_error): New function.
9408 (Fprimitive_undo): Use it.
9409 * print.c (print_error_message): Adjust print style for `user-error'.
9410 * keyboard.c (user_error): New function.
9411 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
9413 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
9415 Do not limit current-time-string to years 1000..9999.
9416 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
9417 (Fcurrent_time_string): Support any year that is supported by the
9418 underlying localtime representation. Don't use asctime, as it
9419 has undefined behavior for years outside the range -999..9999.
9421 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
9423 Fix race conditions involving setenv, gmtime, localtime, asctime.
9424 Without this fix, interrupts could mess up code that uses these
9425 nonreentrant functions, since setting TZ invalidates existing
9426 tm_zone or tzname values, and since most of these functions return
9427 pointers to static storage.
9428 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
9429 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
9430 Grow the critical sections to include not just invoking
9431 localtime/gmtime, but also accessing these functions' results
9432 including their tm_zone values if any, and any related TZ setting.
9433 (format_time_string): Last arg is now struct tm *, not struct tm **,
9434 so that the struct tm is saved in the critical section.
9435 All callers changed. Simplify allocation of initial buffer, partly
9436 motivated by the fact that memory allocation needs to be outside
9437 the critical section.
9439 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
9441 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
9442 with RESET_INTERVAL.
9444 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
9445 Remove duplicated buffer name initialization.
9447 2012-05-02 Jim Meyering <jim@meyering.net>
9449 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
9451 * xfns.c (x_window): Use xstrdup (Bug#11375).
9453 2012-05-02 Eli Zaretskii <eliz@gnu.org>
9455 * xdisp.c (pos_visible_p): If already at a newline from the
9456 display string before the 'while' loop, don't walk back the glyphs
9457 from it3.glyph_row. Solves assertion violation when the display
9458 string begins with a newline (egg.el). (Bug#11367)
9460 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
9462 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
9465 2012-05-01 Glenn Morris <rgm@gnu.org>
9467 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
9468 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
9469 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
9470 All were removed before 23.1.
9472 * dispnew.c: Remove HAVE_LIBNCURSES test;
9473 it is always true on relevant platforms.
9475 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
9476 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
9478 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
9480 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
9482 * .gdbinit (xpr): Remove checks for no longer existing misc types.
9483 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
9486 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
9488 Do not avoid creating empty evaporating overlays (Bug#9642).
9489 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
9490 That is, do not delete an evaporating overlay if it becomes
9491 empty after its bounds are adjusted to fit within its buffer.
9492 This fix caused other problems, and I'm reverting it until we get
9493 to the bottom of them.
9495 2012-04-27 Chong Yidong <cyd@gnu.org>
9497 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
9499 2012-04-27 Eli Zaretskii <eliz@gnu.org>
9501 * xdisp.c (pos_visible_p): If the window start position is beyond
9502 ZV, start the display from buffer beginning. Prevents assertion
9503 violation in init_iterator when the minibuffer window is scrolled
9506 * window.c (window_scroll_pixel_based): Likewise.
9508 2012-04-27 Chong Yidong <cyd@gnu.org>
9510 * keymap.c (where_is_internal): Doc fix (Bug#10872).
9512 2012-04-27 Glenn Morris <rgm@gnu.org>
9514 * fileio.c (Fcopy_file, Fset_file_selinux_context):
9515 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
9517 2012-04-27 Eli Zaretskii <eliz@gnu.org>
9519 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
9520 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
9522 2012-04-26 Eli Zaretskii <eliz@gnu.org>
9524 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
9525 display element, check also the underlying string or buffer
9526 character. (Bug#11341)
9528 * w32menu.c: Include w32heap.h.
9529 (add_menu_item): If the call to AppendMenuW (via
9530 unicode_append_menu) fails, disable Unicode menus only if we are
9531 running on Windows 9X/Me.
9533 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
9535 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
9536 (xgetint): Add missing shift for LSB tags.
9538 2012-04-24 Martin Rudalics <rudalics@gmx.at>
9540 * keyboard.c (read_char): Don't wipe echo area for select window
9541 events: These might get delayed via `mouse-autoselect-window'
9544 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
9546 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
9547 manipulation of :loaded-from data.
9549 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
9551 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
9552 now a cons (bug#11311).
9554 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
9556 Do not create empty overlays with the evaporate property (Bug#9642).
9557 * buffer.c (Fmove_overlay): Delete an evaporating overlay
9558 if it becomes empty after its bounds are adjusted to fit within
9559 its buffer. Without this fix, in a nonempty buffer (let ((o
9560 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
9561 yields an empty overlay that has the evaporate property, which is
9562 not supposed to happen.
9564 Fix minor GTK3 problems found by static checking.
9565 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
9566 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
9567 (struct _EmacsFixedClass, emacs_fixed_get_type):

9575 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
9576 (EMACS_FIXED_GET_CLASS): Remove; unused.
9577 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
9579 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
9580 Problem reported by Juanma Barranquero for Windows -Wunused-function.
9582 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
9584 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
9585 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
9586 (__malloc_size_t, __malloc_ptrdiff_t):
9587 Remove. All uses removed, replaced by the definiens if needed,
9588 since we can assume C89 or better now.
9589 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
9590 (protect_malloc_state, align, get_contiguous_space)
9591 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

9597 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
9598 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
9599 Define using prototypes, not old style.
9600 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
9601 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
9602 (align): Don't assume that signed integer overflow wraps around.
9603 Omit unused local var.
9604 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
9605 (_free_internal_nolock, memalign, mallochook, reallochook):

9679 * sysdep.c [__FreeBSD__]: Minor cleanups.
9680 (list_system_processes, system_process_attributes) [__FreeBSD__]:
9681 Use Emacs indenting style more consistently. Avoid some casts.
9682 Use 'double' consistently rather than mixing 'float' and 'double'.

9723 farther than the first row after the header line, if any.
9724 Don't consider the header-line row as "partially visible", even if
9725 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)

9780 (r_alloc_free) [REL_ALLOC]: Move decls from here ...
9781 * lisp.h (r_alloc, r_alloc_free, r_re_alloc, r_alloc_reset_variable)
9782 [REL_ALLOC]: ... to here, to check interface.
9783 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
9784 Remove decls. This fixes an "It stinks!".
9786 * alloc.c (which_symbols): Fix alignment issue / type clash.
9788 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
9790 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

9801 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
9803 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
9804 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
9805 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
9806 * s/netbsd.h, s/sol2-6.h:
9807 Remove definition of GC_MARK_STACK, since the default now works.
9808 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
9809 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
9810 no longer the default.
9811 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
9813 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
9815 * lread.c (lisp_file_lexically_bound_p):
9816 Fix hang at ";-*-\n" (bug#11238).
9818 2012-04-14 Eli Zaretskii <eliz@gnu.org>
9820 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
9821 "unchanged" if its end.pos is beyond ZV. (Bug#11199)
9823 2012-04-14 Jan Djärv <jan.h.d@swipnet.se>
9825 * nsterm.m (constrainFrameRect): Always constrain when there is only
9826 one screen (Bug#10962).
9828 2012-04-13 Ken Brown <kbrown@cornell.edu>
9830 * s/cygwin.h (PTY_OPEN): Don't try to close a bogus file descriptor.
9832 2012-04-13 Reuben Thomas <rrt@sc3d.org>
9834 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
9836 2012-04-11 Daniel Colascione <dancol@dancol.org>
9838 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
9839 against is gone. It's better to use vfork now so that when Cygwin
9840 gains a new, working vfork, we use it automatically (bug#10398).
9842 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
9844 * window.c (save_window_save): Obey window-point-insertion-type.
9846 2012-04-11 Glenn Morris <rgm@gnu.org>
9848 * Makefile.in (GNUSTEP_CFLAGS): Rename from C_SWITCH_X_SYSTEM.
9850 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
9852 * alloc.c (lisp_align_malloc): Remove unneeded prototype.
9854 2012-04-10 Jason S. Cornez <jcornez@ravenpack.com> (tiny change)
9856 * keyboard.c: Override inhibit-quit after the third C-g (bug#6585).
9857 (force_quit_count): New var.
9858 (handle_interrupt): Use it.
9860 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
9862 * w32.c (w32_delayed_load): Record the full path of the library
9863 being loaded (bug#10424).
9865 2012-04-09 Glenn Morris <rgm@gnu.org>
9867 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
9868 not just in the obarray, before snarfing them. (Bug#11036)
9870 * Makefile.in ($(leimdir)/leim-list.el):
9871 Pass EMACS rather than BUILT_EMACS.
9873 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
9875 * process.c (make_process):
9876 * process.h: Add integer `gnutls_handshakes_tried' member to
9879 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
9880 Add convenience `GNUTLS_LOG2i' macro.
9882 * gnutls.c (gnutls_log_function2i): Convenience log function.
9883 (emacs_gnutls_read): Use new log functions,
9884 `gnutls_handshakes_tried' process member, and
9885 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
9886 attempts per process (connection).
9888 2012-04-09 Chong Yidong <cyd@gnu.org>
9890 * eval.c (Fuser_variable_p, user_variable_p_eh)
9891 (lisp_indirect_variable): Functions deleted.
9892 (Fdefvar): Caller changed.
9894 * callint.c (Finteractive, Fcall_interactively):
9895 * minibuf.c (Fread_variable): Callers changed.
9897 2012-04-09 Eli Zaretskii <eliz@gnu.org>
9899 * xdisp.c (set_cursor_from_row): If the display string appears in
9900 the buffer at position that is closer to point than the position
9901 after the display string, display the cursor on the first glyph of
9902 the display string. Fixes cursor display when a 'display' text
9903 property immediately follows invisible text. (Bug#11094)
9905 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
9907 composite.c: use 'double' consistently
9908 * composite.c (get_composition_id): Use 'double' consistently
9909 instead of converting 'float' to 'double' and vice versa; this is
9910 easier to understand and avoids a GCC warning.
9912 2012-04-09 Glenn Morris <rgm@gnu.org>
9914 * Makefile.in: Generate leim-list with bootstrap-emacs, in
9915 preparation for dumping it with emacs. (Bug#4789)
9916 (leimdir): New variable.
9917 ($(leimdir)/leim-list.el): New rule.
9918 (emacs$(EXEEXT)): Depend on leim-list.el.
9920 * buffer.c (Qucs_set_table_for_input): Remove. (Bug#9821)
9921 (Fget_buffer_create): Don't call Qucs_set_table_for_input.
9922 (init_buffer_once, syms_of_buffer): Remove Qucs_set_table_for_input.
9924 2012-04-08 Andreas Schwab <schwab@linux-m68k.org>
9926 * lisp.h (struct Lisp_Symbol): Add explicit padding to ensure
9929 2012-04-07 Juanma Barranquero <lekktu@gmail.com>
9931 * xml.c (init_libxml2_functions) [WINDOWSNT]:
9932 Remove unused local variable.
9934 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
9936 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
9937 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
9938 (mark_memory): Mark Lisp_Objects only if pointers might hide in
9939 objects, as mark_maybe_pointer will catch them otherwise.
9940 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
9941 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
9943 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
9945 Fix typo that broke non-Windows builds.
9946 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
9948 2012-04-07 Eli Zaretskii <eliz@gnu.org>
9950 Support building on MS-Windows with libxml2.
9952 * makefile.w32-in (OBJ2): Add xml.$(O).
9953 (GLOBAL_SOURCES): Add xml.c.
9954 ($(BLD)/xml.$(O)): New dependency list.
9956 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
9957 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
9958 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
9959 [!WINDOWSNT]: New macros.
9960 (init_libxml2_functions, libxml2_loaded_p): New functions.
9961 (parse_region): Call fn_xmlCheckVersion instead of using the macro
9962 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
9963 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
9964 Calls xmlCleanupParser only if libxml2 was loaded (or statically
9966 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
9967 Call init_libxml2_functions before calling libxml2 functions.
9968 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
9970 * emacs.c: Don't include libxml/parser.h.
9971 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
9972 xmlCleanupParser directly.
9974 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
9976 2012-04-07 Eli Zaretskii <eliz@gnu.org>
9978 * indent.c (Fvertical_motion): If there is a display string at
9979 point, use it.vpos to compute how many lines to backtrack after
9980 move_it_to point. (Bug#11133)
9982 2012-04-06 Eli Zaretskii <eliz@gnu.org>
9984 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
9985 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
9986 about subtle differences between FETCH_CHAR* and STRING_CHAR*
9987 macros related to unification of CJK characters. For the details,
9988 see the discussion following the message here:
9989 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
9991 2012-04-04 Chong Yidong <cyd@gnu.org>
9993 * keyboard.c (Vdelayed_warnings_list): Doc fix.
9995 2012-04-01 Eli Zaretskii <eliz@gnu.org>
9997 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
9998 instead of alloca. (Bug#11138)
10000 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
10002 * w32menu.c (is_simple_dialog): Properly check lisp types.
10005 2012-03-31 Eli Zaretskii <eliz@gnu.org>
10007 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
10008 position we get to after a call to move_it_to fails the
10009 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
10010 only if we wind up in a string from display property. (Bug#11063)
10012 * window.c (Fdelete_other_windows_internal): Invalidate the row
10013 and column information about mouse highlight, so that redisplay
10014 restores it after reallocating the glyph matrices. (Bug#7464)
10016 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
10017 string comes from a `display' text property, use the buffer
10018 position of that property as if we actually saw that position in
10020 (move_it_by_lines): Remove the assertion that
10021 "it->current_x == 0 && it->hpos == 0" which can be legitimately
10022 violated when there's a before-string at the beginning of a line.
10025 2012-03-30 Eli Zaretskii <eliz@gnu.org>
10027 * xdisp.c (append_space_for_newline): If the default face was
10028 remapped, use the remapped face for the appended newline.
10029 (extend_face_to_end_of_line): Use the remapped default face for
10030 extending the face to the end of the line.
10031 (display_line): Call extend_face_to_end_of_line when the default
10032 face was remapped. (Bug#11068)
10034 2012-03-29 Eli Zaretskii <eliz@gnu.org>
10036 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
10038 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
10040 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
10042 2012-03-27 Glenn Morris <rgm@gnu.org>
10044 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
10047 2012-03-26 Kenichi Handa <handa@m17n.org>
10049 * dispextern.h (struct glyph): Fix previous change. Change the
10050 bit length of glyphless.ch to 25 (Bug#11082).
10052 2012-03-26 Chong Yidong <cyd@gnu.org>
10054 * keyboard.c (Vselection_inhibit_update_commands): New variable.
10055 (command_loop_1): Use it; inhibit selection update for
10056 handle-select-window too (Bug#8996).
10058 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
10060 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
10062 2012-03-25 Kenichi Handa <handa@m17n.org>
10064 * dispextern.h (struct glyph): Change the bit length of
10065 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
10067 2012-03-24 Eli Zaretskii <eliz@gnu.org>
10069 * s/ms-w32.h (tzname): Include time.h before redirecting to
10070 _tzname. Fixes the MSVC build. (Bug#9960)
10072 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
10074 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
10077 * xterm.c (XTread_socket): Only modify handling_signal if
10078 !SYNC_INPUT. (Bug#11080)
10080 2012-03-23 Eli Zaretskii <eliz@gnu.org>
10082 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
10083 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
10084 when fetching a multibyte character consumes more bytes than
10085 CHAR_BYTES returns, due to unification of CJK characters in
10086 string_char. (Bug#11073)
10088 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
10090 * process.c (wait_reading_process_output): Handle pty disconnect
10091 by refraining from sending oneself a SIGCHLD (bug#10933).
10093 2012-03-22 Chong Yidong <cyd@gnu.org>
10095 * dispextern.h (struct it): New member string_from_prefix_prop_p.
10097 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
10098 Mark string as coming from a prefix property.
10099 (handle_face_prop): Use default face for prefix strings (Bug#4281).
10100 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
10102 2012-03-21 Chong Yidong <cyd@gnu.org>
10104 * xfaces.c (Vface_remapping_alist): Doc fix.
10106 2012-03-20 Eli Zaretskii <eliz@gnu.org>
10108 * w32proc.c (Fw32_set_console_codepage)
10109 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
10112 2012-03-20 Chong Yidong <cyd@gnu.org>
10114 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
10115 to reflect default non-nil value of redisplay-dont-pause.
10117 2012-03-19 Kenichi Handa <handa@m17n.org>
10119 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
10120 it fit in a valid range (Bug#11003).
10122 2012-03-18 Eli Zaretskii <eliz@gnu.org>
10124 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
10125 that is not from display property, accept the row as a "cursor
10126 row" if one of the string's character has a non-nil `cursor'
10127 property. Fixes cursor positioning when there are newlines in
10128 overlay strings, e.g. in icomplete.el. (Bug#11035)
10130 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
10132 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
10134 2012-03-12 Chong Yidong <cyd@gnu.org>
10136 * eval.c (inhibit_lisp_code): Rename from
10137 inhibit_window_configuration_change_hook; move from window.c.
10139 * xfns.c (unwind_create_frame_1, Fx_create_frame):
10140 * window.c (run_window_configuration_change_hook)
10141 (syms_of_window): Callers changed.
10143 2012-03-11 Chong Yidong <cyd@gnu.org>
10145 * keymap.c (Fkey_description): Doc fix (Bug#9700).
10147 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
10149 2012-03-10 Chong Yidong <cyd@gnu.org>
10151 * frame.c (other_visible_frames): Don't assume the selected frame
10152 is visible (Bug#10955).
10154 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
10156 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
10158 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
10160 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
10161 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
10164 2012-03-03 Glenn Morris <rgm@gnu.org>
10166 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
10168 2012-03-02 Eli Zaretskii <eliz@gnu.org>
10170 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
10171 position past the first glyph_row that ends at ZV. (Bug#10902)
10172 (redisplay_window, next_element_from_string): Fix typos in
10174 (redisplay_window): Pass to move_it_vertically the margin in
10175 pixels, not in screen lines.
10177 2012-03-02 Glenn Morris <rgm@gnu.org>
10179 * buffer.c (buffer-list-update-hook): Doc fix.
10181 2012-02-29 Eli Zaretskii <eliz@gnu.org>
10183 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
10184 push_it before setting up the iterator for the first overlay
10185 string, even if we have an empty string loaded.
10186 (next_overlay_string): If there's an empty string on the iterator
10187 stack, pop the stack. (Bug#10903)
10189 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
10191 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
10192 Suggested by Stefan Monnier in
10193 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
10194 * alloc.c (widen_to_Lisp_Object): New static function.
10195 (mark_memory): Also mark Lisp_Objects by fetching pointer words
10196 and widening them to Lisp_Objects. This would work even if
10197 USE_LSB_TAG is defined and wide integers are used, which might
10198 happen in a future version of Emacs.
10200 2012-02-25 Chong Yidong <cyd@gnu.org>
10202 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
10205 * xselect.c (Fx_selection_exists_p): Doc fix.
10206 (x_clipboard_manager_save_all): Print an informative message
10207 before saving to clipboard manager.
10209 2012-02-24 Chong Yidong <cyd@gnu.org>
10211 * keyboard.c (process_special_events): Handle all X selection
10212 requests in kbd_buffer, not just the next one (Bug#8869).
10214 2012-02-23 Chong Yidong <cyd@gnu.org>
10216 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
10217 call when setting menu-bar-lines and tool-bar-lines parameters.
10218 (unwind_create_frame_1): New helper function.
10220 * window.c (inhibit_window_configuration_change_hook): New var.
10221 (run_window_configuration_change_hook): Obey it.
10222 (syms_of_window): Initialize it.
10224 2012-02-22 Chong Yidong <cyd@gnu.org>
10226 * xterm.c (x_draw_image_relief): Add missing type check for
10227 Vtool_bar_button_margin (Bug#10743).
10229 2012-02-21 Chong Yidong <cyd@gnu.org>
10231 * fileio.c (Vfile_name_handler_alist): Doc fix.
10233 * buffer.c (Fget_file_buffer): Protect against invalid file
10234 handler return value.
10236 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
10238 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
10239 when computing $valmask.
10241 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
10242 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
10243 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
10244 It's useless in that case, and it can cause problems on hosts
10245 that allocate halves of EMACS_INT values separately.
10246 Reported by Dan Horák. Diagnosed by Andreas Schwab in
10247 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
10248 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
10249 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
10250 it avoids undefined behavior on hosts where shifting right by more
10251 than the word width has undefined behavior.
10253 2012-02-19 Chong Yidong <cyd@gnu.org>
10255 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
10256 (Funhandled_file_name_directory, Ffile_name_as_directory)
10257 (Fdirectory_file_name, Fexpand_file_name)
10258 (Fsubstitute_in_file_name): Protect against invalid file handler
10259 return values (Bug#10845).
10261 2012-02-18 Eli Zaretskii <eliz@gnu.org>
10263 * .gdbinit (pitx): Fix incorrect references to fields of the
10266 2012-02-17 Chong Yidong <cyd@gnu.org>
10268 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
10270 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
10272 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
10273 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.

10868 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
10869 verifies glyph row's hash code--we have just reallocated the

11035 is set, removing the need for VIRT_ADDRESS_VARIES.
11036 (PURE_P): Use a more-efficient implementation that needs just one

11053 behave as if the cursor position were at the window margin.
11055 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
11056 and the cursor position is out of bounds, behave as if the cursor
11057 position were at the window margin. (Bug#10075)
11059 2011-11-18 Chong Yidong <cyd@gnu.org>
11061 * window.c (Fwindow_combination_limit): Make first argument

11083 compute_line_metrics.
11084 (compute_line_metrics): Call row_hash, instead of computing the
11087 * dispnew.c (verify_row_hash): Call row_hash for computing the
11088 hash code of a row, instead of duplicating code from xdisp.c.
11090 * dispextern.h (row_hash): Add prototype.
11092 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
11094 * frame.c (delete_frame): Don't delete the terminal when the last

11143 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
11144 with user-defined heap size. Bump the default size of the temacs

11148 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
11149 current_matrix and desired_matrix. (Bug#9990)
11150 (verify_row_hash) [XASSERTS]: New function.

11197 Avoid some portability problems by eschewing 'extern inline' functions.
11198 The trivial performance wins aren't worth the portability hassles; see
11199 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
11201 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

11230 * w32.c (check_windows_init_file): Don't look for term/w32-win.el
11231 if Vpurify_flag is non-nil. Fixes a crash when running w32 build
11232 of temacs in GUI mode.
11234 2011-11-07 Martin Rudalics <rudalics@gmx.at>
11236 * window.h: Declare delete_all_child_windows instead of
11237 delete_all_subwindows.

11239 (Fset_window_new_total, Fset_window_new_normal)
11240 (Fwindow_resize_apply): Don't use term subwindow in doc-strings.
11241 (delete_all_subwindows): Rename to delete_all_child_windows.
11242 (Fdelete_other_windows_internal, Fset_window_configuration):
11243 Call delete_all_child_windows instead of delete_all_subwindows.
11244 * frame.c (delete_frame): Call delete_all_child_windows instead
11245 of delete_all_subwindows.
11247 2011-11-07 Paul Eggert <eggert@cs.ucla.edu>
11249 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
11250 This is also needed for porting to any host where GC_MARK_STACK is
11251 not GC_MAKE_GCPROS_NOOPS.
11252 (which_symbols): Use it.
11254 2011-11-07 Kenichi Handa <handa@m17n.org>
11256 * coding.c (coding_set_destination): Check coding->src_pos only
11257 when coding->src_object is a buffer (bug#9910).

11267 * xmenu.c (cleanup_widget_value_tree): New function.
11268 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
11269 calling free_menubar_widget_value_tree directly (Bug#9830).
11271 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
11273 Fix some portability problems with 'inline'.

11275 (window_box_width, window_box_left, window_box_left_offset)
11276 (window_box_right, window_box_right_offset): Declare extern.
11277 Otherwise, these inline functions do not conform to C99 and
11278 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
11279 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
11280 * intervals.c (adjust_intervals_for_insertion)
11281 (adjust_intervals_for_deletion): Now extern, because otherwise the
11282 extern inline functions 'offset_intervals' couldn't refer to it.
11283 (static_offset_intervals): Remove.
11284 (offset_intervals): Rewrite using the old contents of
11285 static_offset_intervals. The old version didn't conform to C99
11286 because an extern inline function contained a reference to an
11287 identifier with static linkage.
11289 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
11291 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

11309 (Fwindow_vscroll): Doc fix.
11310 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
11311 argument, since it makes no sense to pass a live window and for
11312 consistency with window-child.

11340 (unwind_create_frame): New function (Bug#9943).
11341 (Fx_create_frame): Restructure code to be more similar to the one in
11342 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
11343 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
11344 Move terminal->reference_count++ just before making the frame official

11352 Move terminal->reference_count++ just before making the frame
11353 official. Move initialization of image_cache_refcount and
11354 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

11394 previous/next-single-property-change returns nil, treat that as
11395 the beginning or the end of the buffer. (Bug#9955)
11397 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
11399 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or

11431 2011-10-30 Eli Zaretskii <eliz@gnu.org>
11433 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
11434 past the beginning of the current glyph matrix.
11436 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
11438 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.

11484 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
11485 Not clear what it was for, and it causes various bugs. (Bug#9839)
11487 2011-10-28 Eli Zaretskii <eliz@gnu.org>

11522 (w32font_open_internal, compute_metrics):
11523 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
11524 instead of calling the "wide" APIs directly.
11526 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
11528 * w32.h (syms_of_w32font): Add prototype.
11530 2011-10-27 Juanma Barranquero <lekktu@gmail.com>

11537 2011-10-27 Chong Yidong <cyd@gnu.org>
11539 * process.c (make_process): Set gnutls_state to NULL.
11541 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
11542 non-NULL, regardless of GNUTLS_INITSTAGE.

11591 (bidi_resolve_weak): Don't enter the expensive loop if the current
11592 position is before next_en_pos. Record the bidi type of the first
11593 non-ET, non-BN character we find, in addition to its position.
11594 (bidi_level_of_next_char): Invalidate next_en_type when
11595 next_en_pos is over-stepped.
11597 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
11599 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
11600 * editfns.c: Rewrite current-time-zone so that it invokes
11601 the equivalent of (format-time-string "%Z") to get the time zone name.
11602 This fixes a bug when the time zone name contains characters that
11603 need converting from the system time locale to Emacs internal format.
11604 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
11605 that patch fixed format-time-string to do the conversion, but
11606 I forgot to fix current-time-zone.
11607 (format_time_string): New function, containing most of
11608 what Fformat_time_string used to contain.
11609 (Fformat_time_string): Rewrite in terms of format_time_string.
11610 This doesn't change this function's behavior.
11611 (current-time-zone): Rewrite to use format_time_string.
11612 This fixes the bug reported by Michael Schierl in
11613 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
11614 Jason Rumney's 2007-06-07 change worked around this bug, but
11616 * systime.h (tzname, timezone): Remove no-longer-used declarations.
11618 2011-10-19 Eli Zaretskii <eliz@gnu.org>
11620 * xdisp.c (start_display): If the character at POS is displayed
11621 via a display vector, reset IT->current.dpvec_index to zero.
11622 (try_window_reusing_current_matrix): If a line ends in a display
11623 vector or the next line starts in a display vector, continue
11624 redrawing the window even though the character position of
11625 start_row was reached.
11628 2011-10-18 Chong Yidong <cyd@gnu.org>
11630 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
11631 with nobreak-char-display too.
11633 2011-10-18 Eli Zaretskii <eliz@gnu.org>
11635 Fix part 3 of bug#9771.
11636 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
11637 (bidi_resolve_neutral): Don't enter the expensive loop looking for
11638 non-neutral characters if the current character is a paragraph
11639 separator (a.k.a. Newline). This avoids running the same
11640 expensive loop twice, once when we consume the preceding newline
11641 and the other time when the line actually needs to be displayed.
11642 Avoid the loop when we see neutrals on the base embedding level
11643 following a character whose directionality is the same as the
11644 paragraph's. This avoids running the expensive loop when a line
11645 ends in a long sequence of neutrals, like control characters.
11646 Add assertion against STRONG_AL type. Slightly rearrange code
11647 that determines the type of a neutral given the first non-neutral
11649 (bidi_level_of_next_char): Set next_en_pos to zero when
11650 invalidating its info.
11652 2011-10-17 Eli Zaretskii <eliz@gnu.org>
11654 * xdisp.c (push_display_prop): Determine whether to record string
11655 or buffer position by IT->string, not by IT->method. Allow
11656 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
11657 (move_it_vertically_backward): Don't look for character position
11658 immediately after the newline when in a continuation line.
11661 2011-10-15 Martin Rudalics <rudalics@gmx.at>
11663 * window.c (coordinates_in_window): Rewrite and delabelize
11664 vertical border check. (Bug#5357) (Bug#9618)
11666 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
11668 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
11669 errors in XSetWindowBorder (bug#9310).
11671 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
11673 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
11674 avoid crash when xmalloc overrun checking is enabled.
11676 2011-10-13 Eli Zaretskii <eliz@gnu.org>
11678 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
11679 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
11680 cursor motion with <left> and <right> arrow keys.
11682 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
11683 some callers set that themselves.
11685 2011-10-12 Eli Zaretskii <eliz@gnu.org>
11687 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
11688 display string and the previous row comes from the same string and
11689 is empty. (Bug#9739) (Bug#9738)
11691 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
11693 * doc.c (get_doc_string): Encode file name (bug#9735).
11695 2011-10-12 Eli Zaretskii <eliz@gnu.org>
11697 * bidi.c (bidi_level_of_next_char):
11698 * xdisp.c (get_visually_first_element): Remove old incorrect
11699 comments regarding the Unicode Line Separator character.
11701 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
11703 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
11705 * alloc.c (Fgc_status): Do not access beyond zombies array
11706 boundary if nzombies > MAX_ZOMBIES.
11707 * alloc.c (dump_zombies): Add missing format specifier.
11709 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
11711 * xdisp.c (set_cursor_from_row): Simplify conditionals,
11712 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
11714 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
11715 Some packages use them to denote characters with modifiers.
11717 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
11719 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
11720 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
11721 matching a pp-number. Rename parameter var to var1.
11723 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
11725 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
11727 2011-10-08 Glenn Morris <rgm@gnu.org>
11729 * callint.c (Fcall_interactively): Give a more explicit error for the
11730 'c' case with a non-character input. (Bug#8479)
11732 2011-10-08 Eli Zaretskii <eliz@gnu.org>
11734 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
11736 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
11737 lines that are hscrolled on the left.
11739 * dispnew.c (buffer_posn_from_coords): Account for a possible
11740 presence of header-line. (Bug#4426)
11742 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
11744 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
11745 Don't advertise functionality which we discourage or doesn't work.
11747 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
11749 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
11750 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
11751 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
11752 this makes Emacs dump core during garbage collection on rare
11753 occasions. sizeof is obviously inferior to offsetof here, so
11754 stick with offsetof.
11755 (GC_POINTER_ALIGNMENT): New macro.
11756 (mark_memory): Omit 3rd (offset) arg; caller changed.
11757 Don't assume EMACS_INT alignment is the same as pointer alignment.
11759 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
11761 * keyboard.c (read_key_sequence_remapped): New var.
11762 (read_key_sequence): Compute remapping in the right buffer.
11763 (command_loop_1): Use read_key_sequence's remapping directly.
11765 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
11767 * dired.c (file_name_completion): Don't expand file name.
11768 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
11769 before checking file name handler.
11771 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
11772 they've been requested explicitly (bug#9591).
11774 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
11776 * keymap.c (Fsingle_key_description): Use make_specified_string
11777 instead of build_string to build string from push_key_description.
11780 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
11782 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
11783 This fixes a Y2038 bug on 64-bit hosts.
11784 * buffer.c (reset_buffer):
11785 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
11786 (Fclear_buffer_auto_save_failure):
11787 Use 0, not -1, to represent an unset failure time, since time_t
11788 might not be signed.
11790 Remove dependency on glibc malloc internals.
11791 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11792 Move back here from lisp.h, but with their new implementations.
11793 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11794 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
11795 * charset.c (charset_table_init): New static var.
11796 (syms_of_charset): Use it instead of xmalloc. This removes a
11797 dependency on glibc malloc internals. See Eli Zaretskii's comment in
11798 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
11799 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11800 Move back to alloc.c.
11801 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11802 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
11804 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
11806 * nsterm.m (windowDidResize): Call x_set_window_size only when
11807 ns_in_resize is true. Otherwise set pixelwidth/height and
11808 call change_frame_size (Bug#9628).
11810 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
11812 Port --enable-checking=all to Fedora 14 x86-64.
11813 * charset.c (syms_of_charset): Also account for glibc malloc's
11814 internal overhead when calculating the initial malloc maximum.
11816 Port --enable-checking=all to Fedora 14 x86.
11817 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11819 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
11820 (overrun_check_realloc, overrun_check_free):
11821 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
11822 That way, xmalloc returns a properly-aligned pointer even if
11823 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
11824 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
11825 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
11826 into account when calculating the initial malloc maximum.
11827 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11828 Move here from alloc.c, so that charset.c can use it too.
11829 Properly align; the old code wasn't right for common 32-bit hosts
11830 when configured with --enable-checking=all.
11831 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11832 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
11834 2011-09-29 Eli Zaretskii <eliz@gnu.org>
11836 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
11839 2011-09-28 Eli Zaretskii <eliz@gnu.org>
11841 * xdisp.c (compute_display_string_end): If there's no display
11842 string at CHARPOS, return -1.
11844 * bidi.c (bidi_fetch_char): When compute_display_string_end
11845 returns a negative value, treat the character as a normal
11846 character not covered by a display string. (Bug#9624)
11848 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
11850 * lread.c (Fread_from_string): Fix typo in docstring.
11852 2011-09-27 Eli Zaretskii <eliz@gnu.org>
11854 * xdisp.c (handle_invisible_prop): If invisible text ends on a
11855 newline, reseat the iterator instead of bidi-iterating there one
11856 character at a time. (Bug#9610)
11857 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
11858 TO_CHARPOS if the bidi iterator is at base embedding level.
11860 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
11862 * lread.c (readevalloop): Use correct code for NBSP.
11863 (read1): Likewise. (Bug#9608)
11865 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
11867 * dbusbind.c (Fdbus_register_signal): When service is not
11868 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
11870 2011-09-25 Glenn Morris <rgm@gnu.org>
11872 * buffer.c (truncate-lines): Doc fix.
11874 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
11876 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
11877 (Fset_window_next_buffers): Doc fix.
11879 2011-09-24 Glenn Morris <rgm@gnu.org>
11881 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
11883 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
11885 Fix minor problems found by static checking.
11886 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
11887 * indent.c (Fvertical_motion): Fix == vs = typo.
11889 2011-09-24 Eli Zaretskii <eliz@gnu.org>
11891 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
11892 Default value is now t. Doc fix.
11894 * indent.c (Fvertical_motion): Compute and apply the overshoot
11895 logic when moving up, not only when moving down. Fix the
11896 confusing name and values of the it_overshoot_expected variable;
11897 logic changes accordingly. (Bug#9254) (Bug#9549)
11899 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
11900 CHARPOS is covered by a display string which includes newlines.
11901 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
11902 is covered by a display string with embedded newlines.
11904 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
11906 * dbusbind.c (Fdbus_register_signal): Add match rule to
11907 Vdbus_registered_objects_table. (Bug#9581)
11908 (Fdbus_register_method, Vdbus_registered_objects_table):
11911 2011-09-24 Jim Meyering <meyering@redhat.com>
11913 do not ignore write error for any output size
11914 The previous change was incomplete.
11915 While it makes emacs --batch detect the vast majority of stdout
11916 write failures, errors were still ignored whenever the output size is
11917 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
11918 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
11919 && echo FAIL: ignored write error
11920 FAIL: ignored write error
11921 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
11922 && echo FAIL: ignored write error
11923 FAIL: ignored write error
11924 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
11926 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
11928 * emacs.c (Fkill_emacs): In noninteractive mode exit
11929 non-successfully if a write error occurred on stdout. (Bug#9574)
11931 2011-09-21 Eli Zaretskii <eliz@gnu.org>
11933 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
11936 * dispextern.h (struct it): Update the comment documenting what
11939 2011-09-20 Eli Zaretskii <eliz@gnu.org>
11941 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
11942 a display string, extend search for cursor position to end of row.
11943 (find_row_edges): If the row ends in a newline from a display
11944 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
11945 Handle the case of a display string with multiple newlines.
11946 (Fcurrent_bidi_paragraph_direction): Fix search for previous
11947 non-empty line. Fixes confusing cursor motion with arrow keys at
11948 the beginning of a line that starts with whitespace.
11950 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
11952 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
11955 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
11957 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
11958 boolean (Bug#9154).
11960 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11962 * xdisp.c (display_line): Record maximum and minimum buffer
11963 positions even if no glyphs were produced (e.g., by a zero-width
11964 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
11965 buffer positions that will be removed from the glyph row because
11967 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
11968 column is beyond frame width: don't subtract 1 "pixel" when
11969 computing width of the stretch.
11970 (reseat_at_next_visible_line_start): Undo the change made on
11971 2011-09-17 that saved paragraph information and restored it after
11972 the call to `reseat'. (Bug#9545)
11974 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11976 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
11977 and turn window cursor on if cleared (Bug#9415).
11979 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
11981 * search.c (boyer_moore): Take unibyte characters from pattern
11982 literally. (Bug#9458)
11984 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11986 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
11988 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
11990 Fix minor problem found by static checking.
11991 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
11992 initialized, to pacify gcc -Wuninitialized.
11994 * fileio.c: Report proper errno when syscall falls.
11995 (Finsert_file_contents): Save and restore errno,
11996 so that report_file_error outputs the correct diagnostic.
11997 (Fwrite_region) [CLASH_DETECTION]: Likewise.
11999 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12001 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
12003 2011-09-17 Eli Zaretskii <eliz@gnu.org>
12005 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
12006 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
12008 2011-09-17 Eli Zaretskii <eliz@gnu.org>
12010 * xdisp.c (reseat_at_next_visible_line_start): Keep information
12011 about the current paragraph and restore it after the call to reseat.
12013 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
12014 (bidi_find_paragraph_start): Search back for paragraph beginning
12015 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
12016 (bidi_move_to_visually_next): Only trigger paragraph-related
12017 computations when the last character is a newline or at EOB, not
12018 just any NEUTRAL_B. (Bug#9470)
12020 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
12021 truncated lines if point is covered by a display string. (Bug#9524)
12023 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
12025 * xselect.c: Relax test for outgoing X longs (Bug#9498).
12026 (cons_to_x_long): New function.
12027 (lisp_data_to_selection_data): Use it. Correct the test for
12028 short-versus-long data; it was negated. Break out of vector
12029 loop, for efficiency, when a long datum is discovered.
12031 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
12033 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
12035 2011-09-16 Eli Zaretskii <eliz@gnu.org>
12037 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
12038 GCC PR/17406) by declaring this function with external scope.
12040 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
12042 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).

12045 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
12047 * editfns.c (Fformat): Correctly handle text properties on "%%".
12049 2011-09-15 Eli Zaretskii <eliz@gnu.org>
12051 * xterm.c (x_draw_composite_glyph_string_foreground):
12052 * w32term.c (x_draw_composite_glyph_string_foreground):
12053 * term.c (encode_terminal_code):
12054 * composite.c (composition_update_it, get_composition_id):
12055 * xdisp.c (get_next_display_element)
12056 (fill_composite_glyph_string): Add comments about special meaning
12057 of TAB characters in a composition.
12059 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
12061 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
12062 This occurs when processing a multibyte format.
12063 Problem reported by Wolfgang Jenker.
12065 2011-09-15 Johan Bockgård <bojohan@gnu.org>
12067 * xdisp.c (try_cursor_movement): Only check for exact match if
12068 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
12070 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
12072 Remove unused external symbols.
12073 * dispextern.h (calc_pixel_width_or_height): Remove decl.
12074 * xdisp.c (calc_pixel_width_or_height): Now static.
12075 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
12076 * indent.c (check_display_width):
12077 * w32term.c: Fix comment to match code.
12078 * xterm.c, xterm.h (x_catching_errors): Remove.
12080 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
12082 * xselect.c: Use signed conversions more consistently (Bug#9498).
12083 (selection_data_to_lisp_data): Assume incoming selection data are
12084 signed integers, not unsigned. This is to be consistent with
12085 outgoing selection data, which was modified to use signed integers
12086 in as part of the fix to Bug#9196 in response to Jan D.'s comment
12087 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
12088 expects long, not unsigned long.
12090 2011-09-14 Eli Zaretskii <eliz@gnu.org>
12092 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
12093 computation of loop end. Reported by Johan Bockgård

12098 * frame.c (Fother_visible_frames_p): Function deleted.
12100 2011-09-12 Eli Zaretskii <eliz@gnu.org>
12102 * indent.c (compute_motion): Process display vector front to back
12103 rather than the other way around. (Bug#2496)
12105 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
12107 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
12109 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
12111 * minibuf.c (Fread_from_minibuffer): Doc fix.
12113 2011-09-11 Eli Zaretskii <eliz@gnu.org>
12115 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
12116 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
12118 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>

12121 value for non-existent files.
12123 2011-09-11 Eli Zaretskii <eliz@gnu.org>
12125 * fileio.c (Finsert_file_contents): If the file cannot be opened,
12126 set its "size" to -1. This will set the modtime_size field of
12127 the corresponding buffer to -1, which is what
12128 verify-visited-file-modtime expects for files that do not exist.
12131 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
12133 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
12135 * lisp.h: ... from here. push_key_description is no longer
12136 defined in keyboard.c, so its declaration should not be in
12137 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
12138 logically belongs with push_key_description.
12140 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
12142 * buffer.h: Include <sys/types.h> instead of <time.h>.
12143 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
12144 Problem reported by Herbert J. Skuhra.
12146 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
12148 * xml.c (parse_region): Make the parsing work for
12149 non-comment-starting XML files again (bug#9144).
12151 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
12153 * image.c (gif_load): Fix calculation of bottom and right corner.
12156 2011-09-10 Eli Zaretskii <eliz@gnu.org>
12158 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
12159 redisplay in small windows.
12161 2011-09-09 Eli Zaretskii <eliz@gnu.org>
12163 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
12165 2011-09-08 Martin Rudalics <rudalics@gmx.at>
12167 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
12168 Operate on live windows only.
12170 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
12172 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
12174 2011-09-07 Eli Zaretskii <eliz@gnu.org>
12176 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
12177 only under bidi iteration.
12179 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
12181 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
12183 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12185 isnan: Fix porting problem to Solaris 10 with bundled gcc.
12186 Without this fix, the command to link temacs failed due to an
12187 undefined symbol __builtin_isnan. This is because
12188 /usr/include/iso/math_c99.h #defines isnan(x) to
12189 __builtin_isnan(x), but the bundled gcc, which identifies itself
12190 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
12192 * floatfns.c (isnan): #undef, and then #define to a clone of
12194 (Fisnan): Always define, since it's always available now.
12195 (syms_of_floatfns): Always define isnan at the Lisp level.
12197 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12199 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
12201 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12203 * fileio.c: Fix bugs with large file offsets (Bug#9428).
12204 The previous code assumed that file offsets (off_t values) fit in
12205 EMACS_INT variables, which is not true on typical 32-bit hosts.
12206 The code messed up by falsely reporting buffer overflow in cases
12207 such as (insert-file-contents "big" nil 1 2) into an empty buffer
12208 when "big" contains more than 2**29 bytes, even though this
12209 inserts just one byte and does not overflow the buffer.
12210 (Finsert_file_contents): Store file offsets as off_t
12211 values, not as EMACS_INT values. Check for overflow when
12212 converting between EMACS_INT and off_t. When checking for
12213 buffer overflow or for overlap, take the offsets into account.
12214 Don't use EMACS_INT for small values where int suffices.
12215 When checking for overlap, fix a typo: ZV was used where
12216 ZV_BYTE was intended.
12217 (Fwrite_region): Don't assume off_t fits into 'long'.
12218 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
12220 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
12222 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
12224 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
12226 sprintf-related integer and memory overflow issues (Bug#9412).
12228 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
12229 (esprintf, exprintf, evxprintf): New functions.
12230 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
12231 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
12232 (modify_event_symbol): Do not assume that the length of
12233 name_alist_or_stem is safe to alloca and fits in int.
12234 (Fexecute_extended_command): Likewise for function name and binding.
12235 (Frecursion_depth): Wrap around reliably on integer overflow.
12236 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
12237 since some callers pass EMACS_INT values.
12238 (Fsingle_key_description): Don't crash if symbol name contains more
12239 than MAX_ALLOCA bytes.
12240 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
12241 (get_minibuffer): Arg is now EMACS_INT, not int.
12242 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
12243 (esprintf, exprintf, evxprintf): New decls.
12244 * window.h (command_loop_level, minibuf_level): Reflect API changes.
12246 * dbusbind.c (signature_cat): New function.
12247 (xd_signature, Fdbus_register_signal):
12248 Do not overrun buffer; instead, report string overflow.
12250 * dispnew.c (add_window_display_history): Don't overrun buffer.
12251 Truncate instead; this is OK since it's just a log.
12253 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
12254 even if the time zone offset is outlandishly large.
12255 Don't mishandle offset == INT_MIN.
12257 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
12258 when creating daemon; the previous buffer-overflow check was incorrect.
12260 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
12261 which has the guts of the old verror function.
12263 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
12264 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
12266 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
12267 (font_unparse_xlfd): Don't blindly alloca long strings.
12268 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
12269 fits in int, when using sprintf. Use single snprintf to count
12270 length of string rather than counting it via multiple sprintfs;
12271 that's simpler and more reliable.
12272 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
12273 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
12274 sprintf, in case result does not fit in int.
12276 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
12277 (fontset_from_font): Print it.
12279 * frame.c (tty_frame_count): Now printmax_t, not int.
12280 (make_terminal_frame, set_term_frame_name): Print it.
12281 (x_report_frame_params): In X, window IDs are unsigned long,
12282 not signed long, so print them as unsigned.
12283 (validate_x_resource_name): Check for implausibly long names,
12284 and don't assume name length fits in 'int'.
12285 (x_get_resource_string): Don't blindly alloca invocation name;
12286 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
12289 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
12290 (xg_check_special_colors, xg_set_geometry):
12291 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
12293 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
12294 Use esprintf, not sprintf, in case result does not fit in int.
12296 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
12297 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
12298 it as a large positive number.
12299 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
12300 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
12302 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
12303 in case result does not fit in int.
12305 * print.c (float_to_string): Detect width overflow more reliably.
12306 (print_object): Make sprintf buffer a bit bigger, to avoid potential
12307 buffer overrun. Don't assume list length fits in 'int'. Treat
12308 print length of 0 as 0, not as infinity; to be consistent with other
12309 uses of print length in this function. Don't overflow print length
12310 index. Don't assume hash table size fits in 'long', or that
12311 vectorlike size fits in 'unsigned long'.
12313 * process.c (make_process): Use printmax_t, not int, to format
12314 process-name gensyms.
12316 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
12318 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
12319 to avoid potential buffer overrun.
12321 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
12322 if X resource line is longer than 512 bytes.
12324 * xfns.c (x_window): Make sprintf buffer a bit bigger
12325 to avoid potential buffer overrun.
12327 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
12329 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
12331 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
12333 Integer overflow fixes for scrolling, etc.
12334 Without these, Emacs silently mishandles large integers sometimes.
12335 For example, "C-u 4294967297 M-x recenter" was treated as if
12336 it were "C-u 1 M-x recenter" on a typical 64-bit host.
12338 * xdisp.c (try_window_id): Check Emacs fixnum range before
12339 converting to 'int'.
12341 * window.c (window_scroll_line_based, Frecenter):
12342 Check that an Emacs fixnum is in range before assigning it to 'int'.
12343 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
12344 values converted from Emacs fixnums.
12345 (Frecenter): Don't wrap around a line count if it is out of 'int'
12346 range; instead, treat it as an extreme value.
12347 (Fset_window_configuration, compare_window_configurations):
12348 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
12350 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
12351 that can exceed INT_MAX. Check that EMACS_INT value is in range
12352 before assigning it to the (possibly-narrower) index.
12353 (match_limit): Don't assume that a fixnum can fit in 'int'.
12355 * print.c (print_object): Use ptrdiff_t, not int, for index that can
12358 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
12359 (Fvertical_motion): Don't wrap around LINES values that don't fit
12360 in 'int'. Instead, treat them as extreme values. This is good
12361 enough for windows, which can't have more than INT_MAX lines anyway.
12363 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
12365 * Require libxml/parser.h to avoid compilation warning.
12367 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
12369 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
12370 since this reportedly can destroy thread storage.
12372 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
12374 * syntax.c (find_defun_start): Update all cache variables if
12375 exiting early (Bug#9401).
12377 2011-08-30 Eli Zaretskii <eliz@gnu.org>
12379 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
12381 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
12382 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
12383 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
12385 * term.c (tty_append_glyph): New function.
12386 (produce_stretch_glyph): Static function and its prototype deleted.
12388 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
12391 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
12393 * image.c (parse_image_spec): Check for nonnegative, not for positive,
12394 when checking :margin (Bug#9390).
12395 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
12396 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
12397 so that the name doesn't mislead. All uses changed.
12399 2011-08-28 Johan Bockgård <bojohan@gnu.org>
12401 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
12404 2011-08-27 Eli Zaretskii <eliz@gnu.org>
12406 * xdisp.c (move_it_to): Don't bail out early when reaching
12407 position beyond to_charpos, if we are scanning backwards.
12408 (move_it_vertically_backward): When DY == 0, make sure we get to
12409 the first character in the line after the newline.
12411 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
12413 * ccl.c: Improve and simplify overflow checking (Bug#9196).
12414 (ccl_driver): Do not generate an out-of-range pointer.
12415 (Fccl_execute_on_string): Remove unnecessary check for
12416 integer overflow, noted by Stefan Monnier in
12417 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
12418 Remove a FIXME that didn't need fixing.
12419 Simplify the newly-introduced buffer reallocation code.
12421 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
12423 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
12425 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
12427 Integer and memory overflow issues (Bug#9196).
12429 * doc.c (get_doc_string): Rework so that
12430 get_doc_string_buffer_size is the actual buffer size, rather than
12431 being 1 less than the actual buffer size; this makes xpalloc more
12434 * image.c (x_allocate_bitmap_record, cache_image):
12435 * xselect.c (Fx_register_dnd_atom):
12436 Simplify previous changes by using xpalloc.
12438 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
12439 since either will do and ptrdiff_t is convenient with xpalloc.
12441 * charset.c (charset_table_size)
12442 (struct charset_sort_data.priority): Now ptrdiff_t.
12443 (charset_compare): Don't overflow if priorities differ greatly.
12444 (Fsort_charsets): Don't assume list length fits in int.
12445 Check for size-calculation overflow when allocating sort data.
12446 (syms_of_charset): Allocate an initial charset table that is
12447 just under 64 KiB, to avoid problems with glibc malloc and mmap.
12449 * cmds.c (internal_self_insert): Check for size-calculation overflow.
12451 * composite.h (struct composition.glyph_len): Now int, not unsigned.
12452 The actual value is always <= INT_MAX, and leaving it unsigned made
12453 overflow checking harder.
12455 * dispextern.h (struct glyph_matrix.rows_allocated)
12456 (struct face_cache.size): Now ptrdiff_t, for convenience in use
12457 with xpalloc. The values are still always <= INT_MAX.
12459 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
12461 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
12462 (SAFE_NALLOCA): New macro.
12464 * region-cache.c (struct boundary.pos, find_cache_boundary)
12465 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
12466 (set_cache_region, invalidate_region_cache)
12467 (revalidate_region_cache, know_region_cache, region_cache_forward)
12468 (region_cache_backward, pp_cache):
12469 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
12470 so that ptrdiff_t * can be passed to xpalloc.
12471 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
12472 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
12473 (pp_cache): Don't assume cache_len fits in int.
12474 * region-cache.h: Adjust extern decls to match.
12476 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
12477 EMACS_INT, since either will do, for xpalloc.
12479 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
12480 (xnmalloc, xnrealloc, xpalloc): New functions.
12482 * bidi.c (bidi_shelve_header_size): New constant.
12483 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
12484 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
12486 * bidi.c (bidi_cache_shrink):
12487 * buffer.c (overlays_at, overlays_in, record_overlay_string)
12489 Don't update size of array until after memory allocation succeeds,
12490 because xmalloc/xrealloc may not return.
12491 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
12492 now that we have proper integer overflow checking.
12493 (record_overlay_string, overlay_strings): Catch overflows when
12494 calculating size of overlay_str_buf.
12496 * callproc.c (Fcall_process): Check for size overflow when
12497 calculating size of args2.
12498 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
12499 Normally we prefer signed values, but sticking with ptrdiff_t would
12500 require adding more-complicated checks.
12502 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
12503 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
12504 Redo buffer-overflow calculations to avoid integer overflow.
12505 Add a FIXME comment where memory seems to be over-allocated.
12507 * character.c (Fstring): Check for size-calculation overflow.
12509 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
12510 unnecessary integer overflow. Check for size overflow.
12511 (encode_coding_object): Don't update size until xmalloc succeeds.
12513 * composite.c (get_composition_id): Check for overflow in glyph
12514 length calculations.
12516 Integer and memory overflow fixes for display code.
12517 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
12518 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
12519 (scrolling_window): Check for overflow in size calculations.
12520 (line_draw_cost, realloc_glyph_pool, add_row_entry):
12521 Don't assume glyph table len fits in int.
12522 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
12523 (row_table_size): Now ptrdiff_t, not int.
12524 (scrolling_window): Avoid overflow in size calculations.
12525 Don't update size until allocation succeeds.
12526 * fns.c (concat): Check for overflow in size calculations.
12527 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
12528 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
12529 (NEXT_ALMOST_PRIME_LIMIT): New constant.
12531 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
12532 (get_doc_string): Check for size calculation overflow.
12533 Don't update size until allocation succeeds.
12534 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
12535 EMACS_INT, where ptrdiff_t will do.
12536 (Fsubstitute_command_keys): Check for string overflow.
12538 * editfns.c (set_time_zone_rule): Don't assume environment length
12540 (message_length): Now ptrdiff_t, not int.
12541 (Fmessage_box): Don't update size until allocation succeeds.
12542 Don't assume message length fits in int.
12543 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
12545 * emacs.c (main): Do not reallocate argv, since there is a null at
12546 the end that can be overwritten, and this way there's no need to
12547 worry about size-calculation overflow.
12548 (sort_args): Check for size-calculation overflow.
12550 * eval.c (init_eval_once, grow_specpdl): Don't update size until
12552 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
12554 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
12555 (x_set_scroll_bar_width, x_figure_window_size):
12556 Check for integer overflow.
12557 (x_set_alpha): Do not assume XINT fits in int.
12559 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
12560 This is for the members text_lines, text_cols, total_lines, total_cols,
12561 where the system imposes an 'int' limit.
12563 * fringe.c (Fdefine_fringe_bitmap):
12564 Don't update size until alloc works.
12566 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
12567 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
12569 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
12570 Check for size-calculation overflow.
12571 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
12572 do, as we prefer signed integers.
12573 (id_to_widget.max_size, id_to_widget.used)
12574 (xg_store_widget_in_map, xg_remove_widget_from_map)
12575 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
12576 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
12577 Use and return ptrdiff_t, not int.
12578 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
12579 * gtkutil.h: Change prototypes to match the above.
12581 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these

12628 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
12629 for command line length. Do not attempt to address one before the
12630 beginning of an array, as that's not portable.

12662 memory exhaustion (the usual treatment), rather than aborting.
12664 * xfns.c (x_encode_text, x_set_name_internal)
12665 (Fx_change_window_property): Use ptrdiff_t, not int, to count
12666 sizes, since they can exceed INT_MAX in size. Check for size
12667 calculation overflow.

12670 (xg_select): Check for size calculation overflow.
12671 Don't update size until alloc done.
12673 * xrdb.c (get_environ_db): Don't assume path length fits in int,
12674 as sprintf is limited to int lengths.
12676 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
12677 (X_LONG_MIN): New macros.
12678 Use them to make the following changes clearer.
12679 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
12680 This change doesn't affect the value now, but it may help remind
12681 future maintainers not to raise the value too much later.
12682 (SELECTION_QUANTUM): Remove, replacing with ...
12683 (selection_quantum): ... new function, which avoids overflow.
12685 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
12686 assumption that selection length fits in 'int'.

12703 Don't store size until memory allocation succeeds.
12704 (x_get_window_property): Plug memory leak on memory exhaustion.
12705 Don't double-block input; malloc is safe here. Don't assume 2**34
12706 - 4 fits in unsigned long. Add an xassert to check
12707 XGetWindowProperty overflow. Be more careful about overflow
12708 calculations, and distinguish size from memory overflow better.
12709 (receive_incremental_selection): When tracing, don't assume
12710 unsigned int is less than INT_MAX.
12711 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

12715 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
12716 result parameters unless successful. Rely on cons_to_unsigned
12717 to report problems with elements; the old code wasn't right anyway.
12718 (x_check_property_data): Check for int overflow; we cannot use
12719 a wider type due to X limits.

12752 * lisp.h (hash_lookup, hash_put):
12753 * minibuf.c (Ftest_completion):
12754 Use ptrdiff_t for hash table indexes, not int (which is too
12755 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
12756 32-bit --with-wide-int hosts).
12758 * charset.c (Fdefine_charset_internal): Check for integer overflow.
12759 Add a FIXME comment about memory leaks.

12767 with outlandish widths.
12768 * character.h (sanitize_tab_width): Rename from sanitize_width,
12769 now that we have two such functions. All uses changed.

12787 * xterm.c: Don't go over XClientMessageEvent limit.
12788 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
12789 (x_send_scroll_bar_event): Likewise. Check that the size does not
12790 exceed limits imposed by XClientMessageEvent, as well as the usual
12791 ptrdiff_t and size_t limits.
12793 * keyboard.c: Overflow, signedness and related fixes.
12794 (make_lispy_movement): Use same integer type in forward decl
12795 that is used in the definition.
12796 (read_key_sequence, keyremap_step):
12797 Change bufsize argument back to int, undoing my 2011-03-30 change.
12798 We prefer signed types, and int is wide enough here.
12799 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
12800 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
12801 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
12802 length, not size_t. Use ptrdiff_t for index, not int.
12803 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
12804 possibility of integer overflow.
12806 Overflow, signedness and related fixes for images.

12832 Prefer int to unsigned where either will do.
12833 (tiff_handler): New function, combining the cores of the
12834 old tiff_error_handler and tiff_warning_handler.
12835 This function is rewritten to use vsnprintf and thereby avoid
12836 stack buffer overflows. It uses only the features of vsnprintf
12837 that are common to both POSIX and native Microsoft.
12838 (tiff_error_handler, tiff_warning_handler): Use it.
12839 (tiff_load, gif_load, imagemagick_load_image):
12840 Don't assume :index value fits in 'int'.
12841 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
12842 (imagemagick_load_image): Check that crop parameters fit into
12843 the integer types that MagickCropImage accepts. Don't assume
12844 Vimagemagick_render_type has a nonnegative value. Don't assume
12845 size_t fits in 'long'.
12846 (gs_load): Use printmax_t to print the widest integers possible.

12860 (handle_single_display_spec): If the display spec is of the form
12861 `(space ...)', and specifies display in the text area, return 2
12863 (try_cursor_movement): Check for the need to scroll more
12864 accurately, and prefer exact match for point under bidi.
12865 Don't advance `row' beyond the last row of the window.

12883 buffers, return left-to-right.
12884 (set_cursor_from_row): Consider candidate row a win if its glyph
12885 represents a newline and point is on that newline. Fixes cursor
12886 positioning on the newline at EOL of R2L text within L2R
12887 paragraph, and vice versa.
12888 (try_cursor_movement): Check continued rows, in addition to
12889 continuation rows. Fixes unwarranted scroll when point enters a
12890 continued line of R2L text within an L2R paragraph, or vice versa.
12891 (cursor_row_p): Consider the case of point being equal to
12892 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving

12921 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
12922 instead of CHAR_TO_BYTE. Fixes a crash when a completion
12923 candidate is selected by the mouse, and that candidate has a
12924 composed character under the mouse.
12926 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
12927 coordinates reported by pos-visible-in-window-p for a composed
12928 character in column zero.

12936 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
12937 consider it a hit if to_charpos is anywhere in the range of the
12938 composed buffer positions.
12940 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
12942 * image.c (gif_load): Don't assume that each subimage has the same
12943 dimensions as the base image. Handle disposal method that is
12944 "undefined" by the gif spec (Bug#9335).
12946 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
12948 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

12958 a composition, take its buffer position from IT->cmp_it.charpos.
12959 Fixes cursor positioning at the beginning of a line that begins
12960 with a composed character.
12962 2011-08-18 Eli Zaretskii <eliz@gnu.org>
12964 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
12965 character bidirectional type, use STRONG_L instead. Fixes crashes
12966 in a buffer produced by `describe-categories'.
12968 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
12969 members before the level stack, so they would be saved and
12970 restored when copying iterator state. Fixes incorrect reordering
12971 around TABs covered by display properties.
12973 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

12999 Fix memory allocation problems in Cygwin build (Bug#9273).
13001 * unexcw.c ( __malloc_initialized): Declare external variable.
13002 (fixup_executable): Force the dumped emacs to reinitialize malloc.

13023 * deps.mk (bidi.o): Remove biditype.h and bidimirror.h.
13025 * dispextern.h: Fix a typo in the comment to bidi_type_t.
13027 * chartab.c: Improve commentary for the uniprop_table API.
13029 * bidi.c (bidi_paragraph_init): Support zero value of
13030 bidi_ignore_explicit_marks_for_paragraph_level.
13031 (bidi_initialize): Use uniprop_table instead of including
13032 biditype.h and bidimirror.h.
13034 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
13035 coordinates of the iterator when restoring from ppos_it.
13038 2011-08-14 Kenichi Handa <handa@m17n.org>
13040 * process.c (create_process): Call setup_process_coding_systems
13041 after the pid of the process is set to -1 (Bug#8162).
13043 2011-08-14 Eli Zaretskii <eliz@gnu.org>
13045 * xdisp.c (move_it_in_display_line_to): Don't invoke
13046 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
13047 ppos_it. Fixes vertical cursor motion when line beginning is
13048 covered by an image. (Bug#9296)
13050 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
13052 * nsterm.h (ns_run_ascript): Declare.
13053 (NSAPP_DATA2_RUNASSCRIPT): Define.
13055 * nsfns.m (as_script, as_result, as_status): New static variables.
13056 (ns_run_ascript): New function.
13057 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
13058 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
13059 the event loop. Get status from as_status (Bug#7276).
13061 * nsterm.m (sendEvent): If event is NSApplicationDefined and
13062 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
13063 the event loop (Bug#7276).
13065 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
13067 * gnutls.c (QCgnutls_bootprop_priority)
13068 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
13069 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
13070 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
13071 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
13072 (QCgnutls_bootprop_verify_hostname_error)
13073 (QCgnutls_bootprop_callbacks_verify): Rename from
13074 Qgnutls_bootprop_..., all uses changed.
13076 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
13079 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
13081 * xfaces.c (Qframe_set_background_mode): Now static.
13082 * dispextern.h (Qframe_set_background_mode): Remove decl.
13084 * process.c (Fnetwork_interface_info): Declare local only if needed.
13086 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
13088 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
13089 (Fnetwork_interface_list): Allocate in increments of bytes instead
13090 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
13091 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
13093 (struct ifflag_def): notrailers is smart on OSX.
13094 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
13095 Get hardware address with getifaddrs if available.
13097 2011-08-12 Eli Zaretskii <eliz@gnu.org>
13099 * xdisp.c (iterate_out_of_display_property): xassert that
13100 IT->position is set to within IT->object's boundaries. Break from
13101 the loop as soon as EOB is reached; avoids infloops in redisplay
13102 when IT->position is set up wrongly due to some bug.
13103 Set IT->current to match the bidi iterator unconditionally.
13104 (push_display_prop): Allow GET_FROM_STRING as IT->method on
13105 entry. Force push_it to save on the stack the current
13106 buffer/string position, to be restored by pop_it. Fix flags in
13107 the iterator structure wrt the object coming from a display
13108 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
13109 properties. (Bug#9284)
13111 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
13113 * fontset.c (fontset_get_font_group): Add proper type checks.
13116 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13118 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
13119 and LC_VERSION_MIN_MACOSX.
13120 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
13121 (dump_it) [LC_FUNCTION_STARTS]: Use it.
13123 2011-08-08 Eli Zaretskii <eliz@gnu.org>
13125 * xdisp.c (forward_to_next_line_start): Allow to use the
13126 no-display-properties-and-no-overlays under bidi display.
13127 Set disp_pos in the bidi iterator to avoid searches for display
13128 properties and overlays.
13130 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
13132 * editfns.c (Fset_time_zone_rule): Document relationship with the
13135 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
13136 the font entity extracted from the cache (Bug#8109).
13138 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
13140 * composite.c (autocmp_chars): Don't reset point. That is done by
13141 restore_point_unwind (Bug#5984).
13143 2011-08-07 Juri Linkov <juri@jurta.org>
13145 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
13146 to show the arg `TIME' instead of `TIMEVAL'.
13148 2011-08-06 Eli Zaretskii <eliz@gnu.org>
13150 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
13151 display property strides EOL and includes a newline, as in
13152 longlines-mode. (Bug#9254)
13153 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
13154 word-wrap under bidirectional display. (Bug#9224)
13156 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
13157 is non-zero, even if the data buffer is NULL. Fixes a crash in
13158 vertical-motion with longlines-mode. (Bug#9254)
13160 2011-08-05 Eli Zaretskii <eliz@gnu.org>
13162 * bidi.c <bidi_cache_total_alloc>: Now static.
13163 (bidi_initialize): Initialize bidi_cache_total_alloc.
13165 * xdisp.c (display_line): Release buffer allocated for shelved bidi
13168 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
13169 amount allocated this far in `bidi_cache_total_alloc'.
13170 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
13171 non-zero, only free the data buffer without restoring the cache
13172 contents. All callers changed.
13174 * dispextern.h (bidi_unshelve_cache): Update prototype.
13176 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
13177 (move_it_in_display_line, move_it_to)
13178 (move_it_vertically_backward, move_it_by_lines): Replace the call
13179 to xfree to an equivalent call to bidi_unshelve_cache.
13180 (move_it_in_display_line_to): Fix logic of returning
13181 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
13183 2011-08-05 Eli Zaretskii <eliz@gnu.org>
13185 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
13186 came from a string character with a `cursor' property. (Bug#9229)
13188 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
13190 * Makefile.in (LIB_PTHREAD): New variable.
13191 (LIBES): Add LIB_PTHREAD (Bug#9216).
13193 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
13194 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
13196 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
13198 * regex.c (re_iswctype): Remove some redundant boolean conversions.
13200 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
13202 * xterm.c (x_find_topmost_parent): New function.
13203 (x_set_frame_alpha): Find topmost parent window with
13204 x_find_topmost_parent and set the property there also (bug#9181).
13205 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
13207 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
13209 * callproc.c (Fcall_process): Avoid vfork clobbering
13210 the local vars buffer, coding_systems, current_dir.
13212 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
13214 * keymap.c (Fmake_composed_keymap): Move to subr.el.
13216 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
13218 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
13219 so that it is not optimized away.
13221 * xdisp.c (compute_display_string_pos): Remove unused local.
13223 2011-08-02 Eli Zaretskii <eliz@gnu.org>
13225 Fix slow cursor motion and scrolling in large buffers with
13226 selective display, like Org Mode buffers. (Bug#9218)
13228 * dispextern.h (struct bidi_it): New member disp_prop_p.
13230 * xdisp.c: Remove one-slot cache of display string positions.
13231 (compute_display_string_pos): Accept an additional argument
13232 DISP_PROP_P; callers changed. Scan at most 5K characters forward
13233 for a display string or property. If found, set DISP_PROP_P
13236 * bidi.c (bidi_fetch_char): Accept an additional argument
13237 DISP_PROP_P, and pass it to compute_display_string_pos.
13238 Only handle text covered by a display string if DISP_PROP_P is returned
13239 non-zero. All callers of bidi_fetch_char changed.
13241 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
13243 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
13245 2010-12-03 Don March <don@ohspite.net>
13247 * keymap.c (Fdefine_key): Fix non-prefix key error message when
13248 last character M-[char] is translated to ESC [char] (bug#7541).
13250 2011-08-02 Kenichi Handa <handa@m17n.org>
13252 * lisp.h (uniprop_table): Extern it.
13254 * chartab.c (uniprop_table): Make it non-static.
13256 2011-08-01 Eli Zaretskii <eliz@gnu.org>
13258 * xdisp.c (forward_to_next_line_start): Accept additional argument
13259 BIDI_IT_PREV, and store into it the state of the bidi iterator had
13261 (reseat_at_next_visible_line_start): Use the bidi iterator state
13262 returned by forward_to_next_line_start to restore the state of
13263 it->bidi_it after backing up to previous newline. (Bug#9212)
13265 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
13267 * regex.c (re_comp): Protoize.
13268 (re_exec): Fix return type.
13269 (regexec): Fix type of `ret'. (Bug#9203)
13271 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13273 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
13274 This is needed if max-image-size is a floating-point number.
13276 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
13278 * print.c (print_object): Print empty symbol as ##.
13280 * lread.c (read1): Read ## as empty symbol.
13282 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
13284 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
13285 setting frame foreground color (Bug#9175).
13286 (x_set_background_color): Likewise.
13288 * nsmenu.m (-setText): Size tooltip dimensions precisely to
13289 contents (Bug#9176).
13290 (EmacsTooltip -init): Remove bezels and add shadows to
13293 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
13294 or scroll bar (Bug#8470).
13296 * nsfont.m (nsfont_open): Remove assignment to voffset and
13297 unnecessary vars hshink, expand, hd, full_height, min_height.
13298 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
13300 * nsterm.h (nsfont_info): Remove voffset field.
13302 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
13304 Implement strike-through and overline on NextStep (Bug#8863).
13306 * nsfont.m (nsfont_open): Use underline position provided by font,
13307 instead of hard-coded value of 2.
13308 (nsfont_draw): Call ns_draw_text_decoration instead.
13310 * nsterm.h: Add declaration for ns_draw_text_decoration.
13312 * nsterm.m (ns_draw_text_decoration): New function for drawing
13313 underline, overline, and strike-through.
13314 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
13315 ns_draw_text_decoration. Change treatment of cursor drawing to
13316 accommodate underlining, etc.
13318 2011-07-28 Eli Zaretskii <eliz@gnu.org>
13320 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
13323 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13325 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
13326 Without this fix, if a signal arrives just after memory fills up,
13327 'malloc' might be invoked reentrantly.
13329 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
13330 In other words, assume that every image size is allowed, on non-X
13331 hosts. This assumption is probably wrong, but it lets Emacs compile.
13333 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
13335 * regex.c (re_iswctype): Convert return values to boolean.
13337 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
13339 * xdisp.c (compute_display_string_pos): Don't use cached display
13340 string position if the buffer had its restriction changed.
13343 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13345 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
13347 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13349 Integer signedness and overflow and related fixes. (Bug#9079)
13351 * bidi.c: Integer size and overflow fixes.
13352 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
13353 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
13354 (bidi_cache_find_level_change, bidi_cache_ensure_space)
13355 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
13356 (bidi_find_other_level_edge):
13357 Use ptrdiff_t instead of EMACS_INT where either will do.
13358 This works better on 32-bit hosts configured --with-wide-int.
13359 (bidi_cache_ensure_space): Check for size-calculation overflow.
13360 Use % rather than repeated addition, for better worst-case speed.
13361 Don't set bidi_cache_size until after xrealloc returns, because it
13363 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
13364 (bidi_cache_ensure_space): Also check that the bidi cache size
13365 does not exceed that of the largest Lisp string or buffer. See Eli
13366 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
13368 * alloc.c (__malloc_size_t): Remove.
13369 All uses replaced by size_t. See Andreas Schwab's note
13370 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
13372 * image.c: Improve checking for integer overflow.
13373 (check_image_size): Assume that f is nonnull, since
13374 it is always nonnull in practice. This is one less thing to
13375 worry about when checking for integer overflow later.
13376 (x_check_image_size): New function, which checks for integer
13377 overflow issues inside X.
13378 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
13379 This removes the need for a memory_full check.
13380 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
13381 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
13382 (xbm_read_bitmap_data): Change locals back to 'int', since
13383 their values must fit in 'int'.
13384 (xpm_load_image, png_load, tiff_load):
13385 Invoke x_create_x_image_and_pixmap earlier,
13386 to avoid much needless work if the image is too large.
13387 (tiff_load): Treat overly large images as if
13388 x_create_x_image_and_pixmap failed, not as malloc failures.
13389 (gs_load): Use x_check_image_size.
13391 * gtkutil.c: Omit integer casts.
13392 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
13393 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
13395 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
13397 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
13398 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
13399 would wrongly return t on a 64-bit host.
13401 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
13402 The plain *_OVERFLOW macros run afoul of GCC bug 49705
13403 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
13404 and therefore cause GCC to emit a bogus diagnostic in some cases.
13406 * image.c: Integer signedness and overflow and related fixes.
13407 This is not an exhaustive set of fixes, but it's time to
13408 record what I've got.
13409 (lookup_pixel_color, check_image_size): Remove redundant decls.
13410 (check_image_size): Don't assume that arbitrary EMACS_INT values
13411 fit in 'int', or that arbitrary 'double' values fit in 'int'.
13412 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
13413 (tiff_load, imagemagick_load_image):
13414 Check for overflow in size calculations.
13415 (x_create_x_image_and_pixmap): Remove unnecessary test for
13416 xmalloc returning NULL; that can't happen.
13417 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
13418 (xpm_color_bucket): Use better integer hashing function.
13419 (xpm_cache_color): Don't possibly over-allocate memory.
13420 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
13421 (gif_memory_source):
13422 Use ptrdiff_t, not int or size_t, to record sizes.
13423 (png_load): Don't assume values greater than 2**31 fit in 'int'.
13424 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
13425 either works, as we prefer signed integers.
13426 (tiff_read_from_memory, tiff_write_from_memory):
13427 Return tsize_t, not size_t, since that's what the TIFF API wants.
13428 (tiff_read_from_memory): Don't fail simply because the read would
13429 go past EOF; instead, return a short read.
13430 (tiff_load): Omit no-longer-needed casts.
13431 (Fimagemagick_types): Don't assume size fits into 'int'.
13433 Improve hashing quality when configured --with-wide-int.
13434 * fns.c (hash_string): New function, taken from sxhash_string.
13435 Do not discard information about ASCII character case; this
13436 discarding is no longer needed.
13437 (sxhash-string): Use it. Change sig to match it. Caller changed.
13438 * lisp.h: Declare it.
13439 * lread.c (hash_string): Remove, since we now use fns.c's version.
13440 The fns.c version returns a wider integer if --with-wide-int is
13441 specified, so this should help the quality of the hashing a bit.
13443 * emacs.c: Integer overflow minor fix.
13444 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
13445 Define only if GNU_LINUX.
13446 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
13448 * dispnew.c: Integer signedness and overflow fixes.
13449 Remove unnecessary forward decls, that were a maintenance hassle.
13450 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
13452 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
13453 (scrolling_window): Use ptrdiff_t, not int, for byte count.
13454 (prepare_desired_row, line_draw_cost):
13455 Use int, not unsigned, where either works.
13456 (save_current_matrix, restore_current_matrix):
13457 Use ptrdiff_t, not size_t, where either works.
13458 (init_display): Check for overflow more accurately, and without
13459 relying on undefined behavior.
13461 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
13462 Remove, replacing with the new symbols in lisp.h. All uses changed.
13463 * fileio.c (make_temp_name):
13464 * filelock.c (lock_file_1, lock_file):
13465 * xdisp.c (message_dolog):
13466 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
13467 Use pMd etc. instead.
13468 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
13469 replacing the pWIDE etc. symbols removed from editfns.c.
13471 * keyboard.h (num_input_events): Now uintmax_t.
13472 This is (very slightly) less likely to mess up due to wraparound.
13475 * buffer.c: Integer signedness fixes.
13476 (alloc_buffer_text, enlarge_buffer_text):
13477 Use ptrdiff_t rather than size_t when either will do, as we prefer
13480 * alloc.c: Integer signedness and overflow fixes.
13481 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
13482 (__malloc_size_t): Default to size_t, not to int.
13483 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
13484 (Fgarbage_collect, mark_object_loop_halt, mark_object):
13485 Prefer ptrdiff_t to size_t when either would do, as we prefer
13487 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
13488 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
13489 Now const. Initialize with values that are in range even if char
13491 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
13492 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
13493 These functions do the right thing with sizes > 2**32.
13494 (check_depth): Now ptrdiff_t, not int.
13495 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
13496 Adjust to new way of storing sizes. Check for size overflow bugs
13498 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
13499 slightly wrong anyway, as it missed one instance of
13500 XMALLOC_OVERRUN_CHECK_OVERHEAD.
13501 (refill_memory_reserve): Omit needless cast to size_t.
13502 (mark_object_loop_halt): Mark as externally visible.
13504 * xselect.c: Integer signedness and overflow fixes.
13505 (Fx_register_dnd_atom, x_handle_dnd_message):
13506 Use ptrdiff_t, not size_t, since we prefer signed.
13507 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
13508 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
13509 x_dnd_atoms_size and x_dnd_atoms_length.
13511 * doprnt.c: Prefer signed to unsigned when either works.
13513 * doprnt.c (doprnt):
13515 * xdisp.c (vmessage):
13516 Use ptrdiff_t, not size_t, when using or implementing doprnt,
13517 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
13518 prefer signed arithmetic to avoid comparison confusion.
13519 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
13520 but is a bit tricky.
13522 Assume freestanding C89 headers, string.h, stdlib.h.
13523 * data.c, doprnt.c, floatfns.c, print.c:
13524 Include float.h unconditionally.
13525 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
13526 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
13527 * regex.c: Likewise for stddef.h, string.h.
13528 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
13529 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
13530 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
13531 (STDC_HEADERS): Remove obsolete defines.
13532 * sysdep.c: Include limits.h unconditionally.
13534 Assume support for memcmp, memcpy, memmove, memset.
13535 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
13536 * regex.c (memcmp, memcpy):
13537 Remove; we assume C89 now.
13539 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
13540 (__malloc_safe_bcopy): Remove; no longer needed.
13542 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
13543 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
13544 well either way, and we prefer signed to unsigned.
13546 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
13548 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
13549 closes the connection while we're reading (bug#9182).
13551 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
13553 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
13554 are specified (Bug#9168).
13556 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
13558 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
13559 Found by GCC static checking and --with-wide-int on a 32-bit host.
13561 2011-07-25 Eli Zaretskii <eliz@gnu.org>
13563 * xdisp.c (compute_display_string_pos): Fix logic of caching
13564 previous display string position. Initialize cached_prev_pos to
13565 -1. Fixes slow-down at the beginning of a buffer.
13567 2011-07-24 Eli Zaretskii <eliz@gnu.org>
13569 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
13570 for attrs[LFACE_FONTSET_INDEX].
13572 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
13574 * xml.c (parse_region): Remove unused local
13575 that was recently introduced.
13577 2011-07-23 Eli Zaretskii <eliz@gnu.org>
13579 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
13580 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
13582 * xdisp.c (move_it_in_display_line_to): Record the best matching
13583 position for TO_CHARPOS while scanning the line, and restore it on
13584 exit if none of the characters scanned was an exact match.
13585 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
13586 when exact match is impossible due to invisible text, and the
13587 lines are truncated.
13589 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
13591 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
13594 2011-07-22 Eli Zaretskii <eliz@gnu.org>
13596 Fix a significant slow-down of cursor motion with C-n, C-p,
13597 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
13598 auto-repeat under bidi redisplay in fontified buffers.
13599 * xdisp.c (compute_stop_pos_backwards): New function.
13600 (next_element_from_buffer): Call compute_stop_pos_backwards to
13601 find a suitable prev_stop when we find ourselves before
13603 (reseat): Don't look for prev_stop, as that could mean a very long
13605 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
13606 <cached_disp_overlay_modiff>: Cache for last found display string
13608 (compute_display_string_pos): Return the cached position if asked
13609 about the same buffer in the same area of character positions, and
13610 the buffer wasn't changed since the time the display string
13611 position was cached.
13613 2011-07-22 Eli Zaretskii <eliz@gnu.org>
13615 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
13616 is an integer, which is important for empty lines. (Bug#9149)
13618 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
13620 * frame.c (Fmodify_frame_parameters): In tty case, update the
13621 default face if necessary (Bug#4238).
13623 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
13625 * editfns.c (Fstring_to_char): No need to explain what a character
13626 is in the docstring (Bug#6576).
13628 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
13630 * xml.c (parse_region): Make sure we always return a tree.
13632 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
13634 * xml.c (parse_region): If a document contains only comments,
13637 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
13639 * xml.c (make_dom): Return comments, too.
13641 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
13644 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
13645 and the surrounding thread.
13646 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
13647 rather than fgets, and retry after EINTR. Otherwise, 'emacs
13648 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
13650 * s/openbsd.h (BROKEN_SIGIO): Define.
13651 * unexelf.c (unexec) [__OpenBSD__]:
13652 Don't update the .mdebug section of the Alpha COFF symbol table.
13654 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
13656 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
13659 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
13661 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
13662 This fixes some race conditions on the permissions of any newly
13665 * alloc.c (valid_pointer_p): Use pipe, not open.
13666 This fixes some permissions issues when debugging.
13668 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
13669 If fchown fails to set both uid and gid, try to set just gid,
13670 as that is sometimes allowed. Adjust the file's mode to eliminate
13671 setuid or setgid bits that are inappropriate if fchown fails.
13673 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
13675 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
13676 to compare Lisp_Objects.
13677 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
13678 global_gnutls_log_level, don't mistake it for a Lisp_Object.
13679 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
13681 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
13683 * lread.c (read_integer): Unread even EOF character.
13684 (read1): Likewise. Properly record start position of symbol.
13686 * lread.c (read1): Read `#:' as empty uninterned symbol if no
13687 symbol character follows.
13689 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
13691 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
13692 This works around a problem with the previous change to Fcopy_file.
13693 Recent glibc declares fchown with __attribute__((warn_unused_result)),
13694 and without this change, GCC might complain about discarding
13695 fchown's return value.
13697 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
13699 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
13701 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
13703 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
13705 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
13707 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
13708 it's used from the C level.
13710 * process.c: Use the same condition for POLL_FOR_INPUT in both
13711 keyboard.c and process.c (bug#1858).
13713 2011-07-09 Lawrence Mitchell <wence@gmx.li>
13715 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
13716 (Fgnutls_boot): Use it.
13718 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
13720 * doc.c (Fsubstitute_command_keys): Revert last change.
13722 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
13724 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
13725 quotes the next character, and doesn't affect other longer
13726 sequences (bug#8935).
13728 * lread.c (syms_of_lread): Clarify that is isn't only
13729 `eval-buffer' and `eval-defun' that's affected by
13730 `lexical-binding' (bug#8460).
13732 2011-07-15 Eli Zaretskii <eliz@gnu.org>
13734 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
13735 bidi redisplay when a line includes both an image and is truncated.
13737 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
13739 Fix minor problems found by static checking.
13740 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
13741 (elsz): Now a signed constant, not a size_t var. We prefer signed
13742 types to unsigned, to avoid integer comparison confusion. Without
13743 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
13744 "cannot optimize loop, the loop counter may overflow", a symptom
13746 * indent.c (Fvertical_motion): Mark locals as initialized.
13747 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
13749 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
13751 * search.c (Fre_search_backward): Mention `case-fold-search' in
13752 all the re_search_* functions (bug#8138).
13754 * keyboard.c (Fopen_dribble_file): Document when the file is

13759 * bidi.c (bidi_dump_cached_states): Fix format of displaying
13762 Support bidi reordering of display and overlay strings.

13764 (compute_display_string_end): Accept additional argument STRING.
13765 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
13766 (reseat_to_string): Initialize bidi_it->string.s and
13767 bidi_it->string.schars.
13768 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
13769 NULL (avoids a crash in bidi_paragraph_init).
13770 Initialize itb.string.lstring.
13771 (init_iterator): Call bidi_init_it only of a valid
13772 buffer position was specified. Initialize paragraph_embedding to
13774 (reseat_to_string): Initialize the bidi iterator.
13775 (display_string): If we need to ignore text properties of
13776 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
13777 original value of -1 will not work with bidi.)
13778 (compute_display_string_pos): First arg is now struct
13779 `text_pos *'; all callers changed. Support display properties on
13781 (compute_display_string_end): Support display properties on Lisp
13783 (init_iterator, reseat_1, reseat_to_string): Initialize the
13784 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
13785 when iterating on a string not from display properties).
13786 (compute_display_string_pos, compute_display_string_end):
13787 Fix calculation of the object to scan. Fixes an error when using
13789 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
13790 base_level_stop; instead, set base_level_stop to BEGV.
13791 Fixes crashes in vertical-motion.
13792 (next_element_from_buffer): Improve commentary for when
13793 the iterator is before prev_stop.
13794 (init_iterator): Initialize bidi_p from the default value of
13795 bidi-display-reordering, not from buffer-local value. Use the
13796 buffer-local value only if initializing for buffer iteration.
13797 (handle_invisible_prop): Support invisible properties on strings
13798 that are being bidi-reordered.
13799 (set_iterator_to_next): Support bidi reordering of C strings and
13801 (next_element_from_string): Support bidi reordering of Lisp
13803 (handle_stop_backwards): Support Lisp strings as well.
13804 (display_string): Support display of R2L glyph rows.
13805 Use IT_STRING_CHARPOS when displaying from a Lisp string.
13806 (init_iterator): Don't initialize it->bidi_p for strings
13808 (reseat_to_string): Initialize it->bidi_p for strings here.
13809 (next_element_from_string, next_element_from_c_string)
13810 (next_element_from_buffer): Add xassert's for correspondence
13811 between IT's object being iterated and it->bidi_it.string
13813 (face_before_or_after_it_pos): Support bidi iteration.
13814 (next_element_from_c_string): Handle the case of the first string
13815 character that is not the first one in the visual order.
13816 (get_visually_first_element): New function, refactored from common
13817 parts of next_element_from_buffer, next_element_from_string, and
13818 next_element_from_c_string.
13819 (tool_bar_lines_needed, redisplay_tool_bar)
13820 (display_menu_bar): Force left-to-right direction. Add a FIXME
13821 comment for making that be controlled by a user option.
13822 (push_it, pop_it): Save and restore the state of the
13823 bidi iterator. Save and restore the bidi_p flag.
13824 (pop_it): Iterate out of display property for string iteration as
13826 (iterate_out_of_display_property): Support iteration over strings.
13827 (handle_single_display_spec): Set up it->bidi_it for iteration
13828 over a display string, and call bidi_init_it.
13829 (handle_single_display_spec, next_overlay_string)
13830 (get_overlay_strings_1, push_display_prop): Set up the bidi
13831 iterator for displaying display or overlay strings.
13832 (forward_to_next_line_start): Don't use the shortcut if
13834 (back_to_previous_visible_line_start): If handle_display_prop
13835 pushed the iterator stack, restore the internal state of the bidi
13836 iterator by calling bidi_pop_it same number of times.
13837 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
13838 and we are bidi-iterating, don't decrement the iterator position;
13839 instead, set the first_elt flag in the bidi iterator, to produce
13841 (reseat_1): Remove redundant setting of string_from_display_prop_p.
13842 (push_display_prop): xassert that we are iterating a buffer.
13843 (push_it, pop_it): Save and restore paragraph_embedding member.
13844 (handle_single_display_spec, next_overlay_string)
13845 (get_overlay_strings_1, reseat_1, reseat_to_string)
13846 (push_display_prop): Set up the `unibyte' member of bidi_it.string
13847 correctly. Don't assume unibyte strings are not bidi-reordered.
13848 (compute_display_string_pos)
13849 (compute_display_string_end): Fix handling the case of C string.
13850 (push_it, pop_it): Save and restore from_disp_prop_p.
13851 (handle_single_display_spec, push_display_prop): Set the
13852 from_disp_prop_p flag.
13853 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
13854 (pop_it): Call iterate_out_of_display_property only if we are
13855 popping after iteration over a string that came from a display
13856 property. Fix a typo in popping stretch info. Add an assertion
13857 for verifying that the iterator position is in sync with the bidi
13859 (handle_single_display_spec, get_overlay_strings_1)
13860 (push_display_prop): Fix initialization of paragraph direction for
13861 string when that of the parent object is not yet determined.
13862 (reseat_1): Call bidi_init_it to resync the bidi
13863 iterator with IT's position. (Bug#7616)
13864 (find_row_edges): If ROW->start.pos gives position
13865 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
13866 (handle_stop, back_to_previous_visible_line_start, reseat_1):
13867 Reset the from_disp_prop_p flag.
13868 (SAVE_IT, RESTORE_IT): New macros.
13869 (pos_visible_p, face_before_or_after_it_pos)
13870 (back_to_previous_visible_line_start)
13871 (move_it_in_display_line_to, move_it_in_display_line)
13872 (move_it_to, move_it_vertically_backward, move_it_by_lines)
13873 (try_scrolling, redisplay_window, display_line): Use them when
13874 saving a temporary copy of the iterator and restoring it back.
13875 (back_to_previous_visible_line_start, reseat_1)
13876 (init_iterator): Empty the bidi cache "stack".
13877 (move_it_in_display_line_to): If iterator ended up at
13878 EOL, but we never saw any buffer positions smaller than
13879 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
13880 motion in bidi-reordered lines.
13881 (move_it_in_display_line_to): Record prev_method and prev_pos
13882 immediately before the call to set_iterator_to_next. Fixes cursor
13883 motion in bidi-reordered lines with stretch glyphs and strings
13884 displayed in margins. (Bug#8133) (Bug#8867)
13885 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
13887 (pos_visible_p): Support positions in bidi-reordered lines.
13888 Save and restore bidi cache.
13890 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
13891 (bidi_paragraph_info): Delete unused struct.
13892 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
13893 (bidi_cache_start): New variable.
13894 (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not
13896 (bidi_cache_fetch_state, bidi_cache_search)
13897 (bidi_cache_find_level_change, bidi_cache_iterator_state)
13898 (bidi_cache_find, bidi_peek_at_next_level)

13900 (bidi_move_to_visually_next): Compare cache index with
13901 bidi_cache_start rather than with zero.
13902 (bidi_fetch_char): Accept new argument STRING; all callers
13903 changed. Support iteration over a string. Support strings with
13904 display properties. Support unibyte strings. Fix the type of

14004 The old code sometimes used this field without initializing it.
14006 * alloc.c (gc_sweep): Don't read past end of array.
14007 In theory, the old code could also have corrupted Emacs internals,

14312 Random fixes. E.g., (random) never returned negative values.
14313 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
14314 subseconds part to the entropy, as that's a bit more random.
14315 Prefer signed to unsigned, since the signedness doesn't matter and
14316 in general we prefer signed. When given a limit, use a
14317 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
14318 latter isn't right if USE_2_TAGS_FOR_INTS.
14319 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
14320 not 0..VALMASK. Don't discard "excess" bits that random () returns.

14332 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
14333 This is more efficient than Ffile_directory_p and avoids a minor race.
14335 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
14337 * buffer.c (Foverlay_put): Say what the return value is
14340 * fileio.c (barf_or_query_if_file_exists): Check first if the file
14341 is a directory before asking whether to use the file name
14343 (barf_or_query_if_file_exists): Make the "File is a directory"
14344 error be more correct.
14346 * fns.c (Frequire): Remove the mention of the .gz files, since

14465 * eval.c (struct backtrace): Simplify and port the data structure.
14466 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
14467 signed bit field, as this assumption is not portable and it makes
14468 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
14469 "char debug_on_exit : 1" as this is not portable either; instead,
14470 use the portable "unsigned int debug_on_exit : 1". Remove unused
14471 member evalargs. Remove obsolete comments about cc bombing out.

14661 (read1): Check for integer overflow in radices, and in
14662 read-circle numbers.

14688 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
14689 The following patches are for when GLYPH_DEBUG && !XASSERT.
14690 * dispextern.h (trace_redisplay_p, dump_glyph_string):
14691 * dispnew.c (flush_stdout):
14692 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
14693 Mark as externally visible.
14694 * dispnew.c (check_window_matrix_pointers): Now static.

14705 (debug_method_add): Use va_list and vsprintf rather than relying
14706 on undefined behavior with wrong number of arguments.
14707 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
14708 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
14709 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
14710 since we're not interested in debugging glyphs with old libraries.
14711 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
14712 GCC 4.6.0's static checking.
14714 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

14753 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
14754 (x_session_initialize): Do not assume string length fits in int.
14756 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
14757 This is unlikely, but can occur if DPI is outlandish.
14759 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):

14783 * lread.c (intern, intern_c_string):
14784 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

14788 * gtkutil.c (style_changed_cb): Avoid need for strlen.
14790 * font.c: Don't assume string length fits in int.
14791 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
14792 Use ptrdiff_t, not int.
14793 (font_intern_prop): Don't assume string length fits in int.
14794 Don't assume integer property fits in fixnum.
14795 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
14797 * filelock.c: Fix some buffer overrun and integer overflow issues.
14798 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
14799 Reformulate so as not to need the command string.
14800 Invoke gzip -cd rather than gunzip, as it's more portable.
14801 (lock_info_type, lock_file_1, lock_file):
14802 Don't assume pid_t and time_t fit in unsigned long.
14803 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
14804 (current_lock_owner): Prefer signed type for sizes.
14805 Use memcpy, not strncpy, where memcpy is what is really wanted.
14806 Don't assume (via atoi) that time_t and pid_t fit in int.
14807 Check for time_t and/or pid_t out of range, e.g., via a network share.
14808 Don't alloca where an auto var works fine.
14810 * fileio.c: Fix some integer overflow issues.
14811 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
14812 Don't assume string length fits in int.
14813 (directory_file_name): Don't assume string length fits in long.
14814 (make_temp_name): Don't assume pid fits in int, or that its print
14815 length is less than 20.
14817 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
14819 * coding.c (make_subsidiaries): Don't assume string length fits in int.
14821 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
14823 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
14824 We prefer signed integers, even for size calculations.
14826 * emacs.c: Don't assume string length fits in 'int'.
14827 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
14828 (main): Don't invoke strlen when not needed.
14830 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
14831 (XD_DEBUG_MESSAGE): Don't waste a byte.
14833 * callproc.c (getenv_internal_1, getenv_internal)
14834 (Fgetenv_internal):
14835 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
14837 * lread.c (invalid_syntax): Omit length argument.
14838 All uses changed. This doesn't fix a bug, but it simplifies the
14839 code away from its former Hollerith-constant appearance, and it's
14840 one less 'int' to worry about when looking at integer-overflow issues.
14841 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
14843 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
14844 This didn't break anything, but it didn't help either.
14845 It's confusing to put a bogus integer in a place where the actual
14846 value does not matter.
14847 (LIST_END_P): Remove unused macro and its bogus comment.
14848 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
14850 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
14851 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
14853 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
14854 We prefer signed types, and the value cannot exceed the EMACS_INT
14855 range anyway (because otherwise the length would not be representable).
14856 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
14857 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
14858 This avoids a GCC warning when WIDE_EMACS_INT.
14860 * indent.c (sane_tab_width): New function.
14861 (current_column, scan_for_column, Findent_to, position_indentation)
14862 (compute_motion): Use it. This is just for clarity.
14863 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
14865 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
14867 * lisp.h (lint_assume): New macro.
14868 * composite.c (composition_gstring_put_cache):
14869 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
14871 * editfns.c, insdel.c:
14872 Omit unnecessary forward decls, to simplify future changes.
14874 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
14876 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
14878 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
14879 Use much-faster test for byte-length change.
14880 Don't assume string byte-length fits in 'int'.
14881 Check that character arg fits in 'int'.
14882 (mapcar1): Declare byte as byte, for clarity.
14884 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
14886 * fns.c (concat): Catch string overflow earlier.
14887 Do not rely on integer wraparound.
14889 * dispextern.h (struct it.overlay_strings_charpos)
14890 (struct it.selective): Now EMACS_INT, not int.
14891 * xdisp.c (forward_to_next_line_start)
14892 (back_to_previous_visible_line_start)
14893 (reseat_at_next_visible_line_start, next_element_from_buffer):
14894 Don't arbitrarily truncate the value of 'selective' to int.
14896 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
14898 * composite.c: Don't truncate sizes to 'int'.
14899 (composition_gstring_p, composition_reseat_it)
14900 (composition_adjust_point): Use EMACS_INT, not int.
14901 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
14902 not EMACS_UINT, for indexes.
14904 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
14906 * buffer.c: Include <verify.h>.
14907 (struct sortvec.priority, struct sortstr.priority):
14908 Now EMACS_INT, not int.
14909 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
14910 (struct sortstr.size, record_overlay_string)
14911 (struct sortstrlist.size, struct sortlist.used):
14912 Don't truncate size to int.
14913 (record_overlay_string): Check for size-calculation overflow.
14914 (init_buffer_once): Check at compile-time, not run-time.
14916 2011-06-22 Jim Meyering <meyering@redhat.com>
14918 Don't leak an XBM-image-sized buffer
14919 * image.c (xbm_load): Free the image buffer after using it.
14921 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
14924 * composite.c (find_automatic_composition): Omit needless 'return 0;'
14925 that Sun C diagnosed.
14926 * fns.c (secure_hash): Fix pointer signedness issue.
14927 * intervals.c (static_offset_intervals): New function.
14928 (offset_intervals): Use it.
14930 2011-06-21 Leo Liu <sdl.web@gmail.com>
14933 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
14936 * fns.c (secure_hash): Rename from crypto_hash_function and change
14937 the first arg to accept symbols.
14938 (Fsecure_hash): New primitive.
14939 (syms_of_fns): New symbols.
14941 2011-06-20 Deniz Dogan <deniz@dogan.se>
14943 * process.c (Fset_process_buffer): Clarify return value in
14946 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
14948 * dispnew.c (add_window_display_history): Use BVAR.
14950 * xdisp.c (debug_method_add): Use BVAR.
14951 (check_window_end, dump_glyph_matrix, dump_glyph)
14952 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
14954 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
14957 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
14958 check till after the cache is created in init_frame_faces.
14960 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
14962 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
14964 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
14966 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
14967 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
14968 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
14970 Improve buffer-overflow checking (Bug#8873).
14971 * fileio.c (Finsert_file_contents):
14972 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
14973 Remove the old (too-loose) buffer overflow checks.
14974 They weren't needed, since make_gap checks for buffer overflow.
14975 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
14976 The old code merely checked for Emacs fixnum overflow, and relied
14977 on undefined (wraparound) behavior. The new code avoids undefined
14978 behavior, and also checks for ptrdiff_t and/or size_t overflow.
14980 * editfns.c (Finsert_char): Don't dump core with very negative counts.
14981 Tune. Don't use wider integers than needed. Don't use alloca.
14982 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
14984 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
14986 * insdel.c, lisp.h (buffer_overflow): New function.
14987 (insert_from_buffer_1, replace_range, replace_range_2):
14988 * insdel.c (make_gap_larger):
14989 * editfns.c (Finsert_char):
14990 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
14992 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
14994 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
14996 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
14998 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
14999 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
15001 * fileio.c: Don't assume EMACS_INT fits in off_t.
15002 (emacs_lseek): New static function.
15003 (Finsert_file_contents, Fwrite_region): Use it.
15004 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
15006 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
15008 * fns.c: Don't overflow int when computing a list length.
15009 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
15010 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
15011 truncation on 64-bit hosts. Check for QUIT every
15012 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
15013 faster and is responsive enough.
15014 (Flength): Report an error instead of overflowing an integer.
15015 (Fsafe_length): Return a float if the value is not representable
15016 as a fixnum. This shouldn't happen except in contrived situations.
15017 (Fnthcdr, Fsort): Don't assume list length fits in int.
15018 (Fcopy_sequence): Don't assume vector length fits in int.
15020 * alloc.c: Check that resized vectors' lengths fit in fixnums.
15021 (header_size, word_size): New constants.
15022 (allocate_vectorlike): Don't check size overflow here.
15023 (allocate_vector): Check it here instead, since this is the only
15024 caller of allocate_vectorlike that could cause overflow.
15025 Check that the new vector's length is representable as a fixnum.
15027 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
15028 The previous code was bogus. For example, next_almost_prime (32)
15029 returned 39, which is undesirable as it is a multiple of 3; and
15030 next_almost_prime (24) returned 25, which is a multiple of 5 so
15031 why was the code bothering to check for multiples of 7?
15033 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
15035 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
15037 Variadic C functions now count arguments with ptrdiff_t.
15038 This partly undoes my 2011-03-30 change, which replaced int with size_t.
15039 Back then I didn't know that the Emacs coding style prefers signed int.
15040 Also, in the meantime I found a few more instances where arguments
15041 were being counted with int, which may truncate counts on 64-bit
15042 machines, or EMACS_INT, which may be unnecessarily wide.
15043 * lisp.h (struct Lisp_Subr.function.aMANY)
15044 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
15045 Arg counts are now ptrdiff_t, not size_t.
15046 All variadic functions and their callers changed accordingly.
15047 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
15048 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
15049 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
15050 * callint.c (Fcall_interactively): Check arg count for overflow,
15051 to avoid potential buffer overrun. Use signed char, not 'int',
15052 for 'varies' array, so that we needn't bother to check its size
15053 calculation for overflow.
15054 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
15055 * eval.c (apply_lambda):
15056 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
15057 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
15058 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
15060 * callint.c (Fcall_interactively): Don't use index var as event count.
15062 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
15063 * mem-limits.h (SIZE): Remove; no longer used.
15065 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
15067 Remove unnecessary casts.
15068 * xterm.c (x_term_init):
15069 * xfns.c (x_set_border_pixel):
15070 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
15071 These aren't needed now that we assume ANSI C.
15073 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
15074 It's more likely to cause problems (due to unsigned overflow)
15077 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
15079 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
15081 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
15083 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
15085 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
15087 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
15089 GLYPH_CODE_FACE returns EMACS_INT, not int.
15090 * dispextern.h (merge_faces):
15091 * xfaces.c (merge_faces):
15092 * xdisp.c (get_next_display_element, next_element_from_display_vector):
15093 Don't assume EMACS_INT fits in int.
15095 * character.h (CHAR_VALID_P): Remove unused parameter.
15096 * fontset.c, lisp.h, xdisp.c: All uses changed.
15098 * editfns.c (Ftranslate_region_internal): Omit redundant test.
15100 * fns.c (concat): Minor tuning based on overflow analysis.
15101 This doesn't fix any bugs. Use int to hold character, instead
15102 of constantly refetching from Emacs object. Use XFASTINT, not
15103 XINT, for value known to be a character. Don't bother comparing
15104 a single byte to 0400, as it's always less.
15106 * floatfns.c (Fexpt):
15107 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
15109 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
15112 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
15114 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
15115 Without this fix, on a 64-bit host (aset S 0 4294967386) would
15116 incorrectly succeed when S was a string, because 4294967386 was
15117 truncated before it was used.
15119 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
15120 Otherwise, an out-of-range integer could cause undefined behavior
15123 * composite.c: Use int, not EMACS_INT, for characters.
15124 (fill_gstring_body, composition_compute_stop_pos): Use int, not
15125 EMACS_INT, for values that are known to be in character range.
15126 This doesn't fix any bugs but is the usual style inside Emacs and
15127 may generate better code on 32-bit machines.
15129 Make sure a 64-bit char is never passed to ENCODE_CHAR.
15130 This is for reasons similar to the recent CHAR_STRING fix.
15131 * charset.c (Fencode_char): Check that character arg is actually
15132 a character. Pass an int to ENCODE_CHAR.
15133 * charset.h (ENCODE_CHAR): Verify that the character argument is no
15134 wider than 'int', as a compile-time check to prevent future regressions
15137 * character.c (char_string): Remove unnecessary casts.
15139 Make sure a 64-bit char is never passed to CHAR_STRING.
15140 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
15141 by silently ignoring the top 32 bits, allowing some values
15142 that were far too large to be valid characters.
15143 * character.h: Include <verify.h>.
15144 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
15145 arguments are no wider than unsigned, as a compile-time check
15146 to prevent future regressions in this area.
15148 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
15149 (Fsubst_char_in_region):
15151 * xdisp.c (decode_mode_spec_coding):
15152 Adjust to CHAR_STRING's new requirement.
15153 * editfns.c (Finsert_char, Fsubst_char_in_region):
15154 * fns.c (concat): Check that character args are actually
15155 characters. Without this test, these functions did the wrong
15156 thing with wildly out-of-range values on 64-bit hosts.
15158 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
15159 These casts should not be needed on 32-bit hosts, either.
15160 * keyboard.c (read_char):
15161 * lread.c (Fload): Remove casts to unsigned.
15163 * lisp.h (UNSIGNED_CMP): New macro.
15164 This fixes comparison bugs on 64-bit hosts.
15165 (ASCII_CHAR_P): Use it.
15166 * casefiddle.c (casify_object):
15167 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
15168 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
15169 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
15170 * dispextern.h (FACE_FROM_ID):
15171 * keyboard.c (read_char): Use UNSIGNED_CMP.
15173 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
15174 not to EMACS_INT, to avoid GCC warning.
15176 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
15178 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
15179 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
15180 isn't needed on 32-bit machines.
15182 * buffer.c (Fgenerate_new_buffer_name):
15183 Use EMACS_INT for count, not int.
15184 (advance_to_char_boundary): Return EMACS_INT, not int.
15186 * data.c (Qcompiled_function): Now static.
15188 * window.c (window_body_lines): Now static.
15190 * image.c (gif_load): Rename local to avoid shadowing.
15192 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
15193 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
15194 * alloc.c (make_save_value): Integer argument is now of type
15195 ptrdiff_t, not int.
15196 (mark_object): Use ptrdiff_t, not int.
15197 * lisp.h (pD): New macro.
15198 * print.c (print_object): Use it.
15200 * alloc.c: Use EMACS_INT, not int, to count objects.
15201 (total_conses, total_markers, total_symbols, total_vector_size)
15202 (total_free_conses, total_free_markers, total_free_symbols)
15203 (total_free_floats, total_floats, total_free_intervals)
15204 (total_intervals, total_strings, total_free_strings):
15205 Now EMACS_INT, not int. All uses changed.
15206 (Fgarbage_collect): Compute overall total using a double, so that
15207 integer overflow is less likely to be a problem. Check for overflow
15208 when converting back to an integer.
15209 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
15210 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
15211 These were 'int' variables that could overflow on 64-bit hosts;
15212 they were never used, so remove them instead of repairing them.
15213 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
15214 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
15215 Previously, this ceilinged at INT_MAX, but that doesn't work on
15217 (allocate_pseudovector): Don't use EMACS_INT when int would do.
15219 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
15220 (allocate_vectorlike): Check for ptrdiff_t overflow.
15221 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
15222 when a (possibly-narrower) signed value would do just as well.
15223 We prefer using signed arithmetic, to avoid comparison confusion.
15225 * alloc.c: Catch some string size overflows that we were missing.
15226 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
15227 for convenience in STRING_BYTES_MAX.

15668 malloc) and ptrdiff_t (for sanity and safety).
15670 * fileio.c (Fverify_visited_file_modtime): Avoid time overflow
15671 if b->modtime has its maximal value.
15673 * dired.c (Ffile_attributes): Don't assume EMACS_INT has >32 bits.
15675 Don't assume time_t can fit into int.
15676 * buffer.h (struct buffer.modtime): Now time_t, not int.
15677 * fileio.c (Fvisited_file_modtime): No need for time_t cast now.
15678 * undo.c (Fprimitive_undo): Use time_t, not int, for time_t value.
15680 Minor fixes for signed vs unsigned integers.
15681 * character.h (MAYBE_UNIFY_CHAR):
15682 * charset.c (maybe_unify_char):
15683 * keyboard.c (read_char, reorder_modifiers):
15684 XINT -> XFASTINT, since the integer must be nonnegative.
15685 * ftfont.c (ftfont_spec_pattern):
15686 * keymap.c (access_keymap, silly_event_symbol_error):
15687 XUINT -> XFASTINT, since the integer must be nonnegative.
15688 (Fsingle_key_description, preferred_sequence_p): XUINT -> XINT,
15689 since it makes no difference and we prefer signed.
15690 * keyboard.c (record_char): Use XUINT when all the neighbors do.
15691 (access_keymap): NATNUMP -> INTEGERP, since the integer must be

15737 (Fselected_window, select_window, Fselect_window): Move up in
15738 code. Minor doc-string fixes.
15740 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
15742 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
15743 Do not assume that spare memory exists; that assumption is valid
15744 only if SYSTEM_MALLOC.
15745 (LARGE_REQUEST): New macro, so that the issue of large requests
15746 is separated from the issue of spare memory.
15748 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
15750 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

15776 New error handlers.
15777 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
15778 Obey Vx_select_enable_clipboard_manager. Catch errors in
15779 x_clipboard_manager_save (Bug#8779).
15780 (Vx_select_enable_clipboard_manager): New variable.
15781 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
15783 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
15785 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
15787 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15789 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
15790 in the current matrix if keep_current_p is non-zero.

15802 (bidi_cache_search, bidi_cache_iterator_state)
15803 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
15804 (bidi_level_of_next_char, bidi_move_to_visually_next):
15805 Support character positions inside a run of characters covered by a
15807 (bidi_paragraph_init, bidi_resolve_explicit_1)
15808 (bidi_level_of_next_char): Call bidi_fetch_char and
15809 bidi_fetch_char_advance instead of FETCH_CHAR and

15812 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
15814 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
15815 instead of using explicit *_CHAR codes.
15816 (bidi_resolve_explicit, bidi_resolve_weak):
15817 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
15818 bidirectional text is supported only in multibyte buffers.
15819 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
15820 it to initialize the frame_window_p member of struct bidi_it.
15821 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
15822 (bidi_resolve_explicit, bidi_resolve_weak)

15824 bidi_it->nchars is non-positive.
15825 (bidi_level_of_next_char): Don't try to lookup the cache for the
15826 next/previous character if nothing is cached there yet, or if we
15827 were just reseat()'ed to a new position.
15829 * xdisp.c (set_cursor_from_row): Set start and stop points
15830 according to the row's direction when priming the loop that looks
15831 for the glyph on which to display cursor.
15832 (single_display_spec_intangible_p): Function deleted.
15833 (display_prop_intangible_p): Reimplement to call
15834 handle_display_spec instead of single_display_spec_intangible_p.
15835 Accept 3 additional arguments needed by handle_display_spec.
15836 This fixes incorrect cursor motion across display property with complex
15837 values: lists, `(when COND...)' forms, etc.
15838 (single_display_spec_string_p): Support property values that are
15839 lists with the argument STRING its top-level element.
15840 (display_prop_string_p): Fix the condition for processing a
15841 property that is a list to be consistent with handle_display_spec.
15842 (handle_display_spec): New function, refactored from the
15843 last portion of handle_display_prop.
15844 (compute_display_string_pos): Accept additional argument
15845 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
15846 value of a `display' property is a "replacing spec".
15847 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
15848 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
15849 the display property, but just return a value indicating whether
15850 the display property will replace the characters it covers.
15851 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
15852 frame_window_p members of struct bidi_it.
15853 (compute_display_string_pos, compute_display_string_end):
15855 (push_it): Accept second argument POSITION, where pop_it should
15856 jump to continue iteration.
15857 (reseat_1): Initialize bidi_it.disp_pos.
15859 * keyboard.c (adjust_point_for_property): Adjust the call to
15860 display_prop_intangible_p to its new signature.
15862 * dispextern.h (struct bidi_it): New member frame_window_p.
15863 (bidi_init_it): Update prototypes.
15864 (display_prop_intangible_p): Update prototype.
15865 (compute_display_string_pos, compute_display_string_end):

15870 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
15872 Malloc failure behavior now depends on size of allocation.
15873 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
15874 * lisp.h: Change signatures accordingly.
15875 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
15876 All callers changed. (Bug#8762)
15878 * gnutls.c: Use Emacs's memory allocators.
15879 Without this change, the gnutls library would invoke malloc etc.
15880 directly, which causes problems on non-SYNC_INPUT hosts, and which
15881 runs afoul of improving memory_full behavior. (Bug#8761)
15882 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
15883 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
15884 xfree instead of the default malloc, realloc, free.
15885 (Fgnutls_boot): No need to check for memory allocation failure,
15886 since xmalloc does that for us.
15888 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
15889 * category.c (hash_get_category_set):
15890 * ccl.c (ccl_driver):

15903 (Fsxhash, Fgethash, Fputhash, Fmaphash):
15904 * image.c (make_image, search_image_cache, lookup_image)
15905 (xpm_put_color_table_h):
15906 * lisp.h (struct Lisp_Hash_Table):
15907 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
15908 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
15909 for hashes and hash indexes, instead of 'unsigned' and 'int'.
15910 * alloc.c (allocate_vectorlike):
15911 Check for overflow in vector size calculations.
15912 * ccl.c (ccl_driver):
15913 Check for overflow when converting EMACS_INT to int.
15914 * fns.c, image.c: Remove unnecessary static decls that would otherwise
15915 need to be updated by these changes.
15916 * fns.c (make_hash_table, maybe_resize_hash_table):
15917 Check for integer overflow with large hash tables.
15918 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
15919 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
15920 (SXHASH_REDUCE): New macro.
15921 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
15922 Use it instead of discarding useful hash info with large hash values.
15923 (sxhash_float): New function.
15924 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
15925 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
15926 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
15927 Rewrite to use FIXNUM_BITS, as this simplifies things.
15928 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
15929 Adjust signatures to match updated version of code.
15930 (consing_since_gc): Now EMACS_INT, since a single hash table can
15931 use more than INT_MAX bytes.
15933 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
15935 Make it possible to build with GCC-4.6+ -O2 -flto.
15937 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
15939 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
15941 * minibuf.c (get_minibuffer, read_minibuf_unwind):
15942 Call minibuffer-inactive-mode.
15944 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
15946 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
15947 Update dependencies.
15949 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15951 * data.c (init_data): Remove code for UTS, this system is not
15954 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15956 Don't force ./temacs to start in terminal mode.
15958 * frame.c (make_initial_frame): Initialize faces in all cases, not
15959 only when CANNOT_DUMP is defined.
15960 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
15962 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15964 * dispnew.c (add_window_display_history): Use const for the string
15965 pointer. Remove declaration, not needed.
15967 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
15969 Use 'inline', not 'INLINE'.
15970 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
15971 * alloc.c, fontset.c (INLINE): Remove.
15972 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
15973 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
15974 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
15975 * gmalloc.c (register_heapinfo): Use inline unconditionally.
15976 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
15978 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15980 Make it possible to run ./temacs.
15982 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
15983 syms_of_callproc does the same thing. Remove test for
15984 "initialized", do it in the caller.
15985 * emacs.c (main): Avoid calling set_initial_environment when dumping.
15987 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
15989 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.

15999 (CCL_CODE_MIN): New macro.
16001 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
16003 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
16005 * eval.c (Qdebug): Now static.
16006 * lisp.h (Qdebug): Remove decl. This reverts a part of the
16007 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
16008 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
16010 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
16012 * image.c: Various fixes to ImageMagick code comments.
16013 (Fimagemagick_types): Doc fix.
16015 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
16017 Minor fixes prompted by GCC 4.6.0 warnings.
16019 * xselect.c (converted_selections, conversion_fail_tag): Now static.
16021 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
16022 (x_clipboard_manager_save_all): Move extern decl to ...
16023 * xterm.h: ... here, so that it can be checked for consistency.
16025 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
16027 * xselect.c (x_clipboard_manager_save_frame)
16028 (x_clipboard_manager_save_all): New functions.
16029 (Fx_clipboard_manager_save): Lisp function deleted.

16032 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
16034 * xterm.h: Update prototype.
16036 2011-05-28 William Xu <william.xwl@gmail.com>
16038 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
16039 exiting (Bug#8239).
16041 2011-05-28 Jim Meyering <meyering@redhat.com>
16043 Avoid a sign-extension bug in crypto_hash_function.
16044 * fns.c (to_uchar): Define.
16045 (crypto_hash_function): Use it to convert some newly-signed
16046 variables to unsigned, to avoid sign-extension bugs. For example,
16047 without this change, (md5 "truc") would evaluate to
16048 45723a2aff78ff4fff7fff1114760e62 rather than the expected
16049 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
16050 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
16052 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
16054 Integer overflow fixes.
16056 * dbusbind.c: Serial number integer overflow fixes.
16057 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
16058 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
16059 to hold a serial number that is too large for a fixnum.
16060 (Fdbus_method_return_internal, Fdbus_method_error_internal):
16061 Check for serial numbers out of range. Decode any serial number
16062 that was so large that it became a float. (Bug#8722)
16064 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
16065 (Fdbus_call_method, Fdbus_call_method_asynchronously):
16066 Use XFASTINT rather than XUINT when numbers are nonnegative.
16067 (xd_append_arg, Fdbus_method_return_internal):
16068 (Fdbus_method_error_internal): Likewise. Also, for unsigned
16069 arguments, check that Lisp number is nonnegative, rather than
16070 silently wrapping negative numbers around. (Bug#8722)
16071 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
16074 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
16076 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
16078 ccl: Add integer overflow checks.
16079 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
16080 (IN_INT_RANGE): New macros.
16081 (ccl_driver): Use them to check for integer overflow when
16082 decoding a CCL program. Many of the new checks are whether XINT (x)
16083 fits in int; it doesn't always, on 64-bit hosts. The new version
16084 doesn't catch all possible integer overflows, but it's an
16085 improvement. (Bug#8719)
16087 * alloc.c (make_event_array): Use XINT, not XUINT.
16088 There's no need for unsigned here.
16090 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
16091 This follows up to the 2011-05-06 change that substituted uintptr_t
16092 for EMACS_INT. This case wasn't caught back then.
16094 Rework Fformat to avoid integer overflow issues.
16095 * editfns.c: Include <float.h> unconditionally, as it's everywhere
16096 now (part of C89). Include <verify.h>.
16097 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
16098 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
16099 (Fformat): Avoid the prepass trying to compute sizes; it was only
16100 approximate and thus did not catch overflow reliably. Instead, walk
16101 through the format just once, formatting and computing sizes as we go,
16102 checking for integer overflow at every step, and allocating a larger
16103 buffer as needed. Keep track separately whether the format is
16104 multibyte. Keep only the most-recently calculated precision, rather
16105 than them all. Record whether each argument has been converted to
16106 string. Use EMACS_INT, not int, for byte and char and arg counts.
16107 Support field widths and precisions larger than INT_MAX. Avoid
16108 sprintf's undefined behavior with conversion specifications such as %#d
16109 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
16110 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
16111 formatting out-of-range floating point numbers with int
16112 formats. (Bug#8668)
16114 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
16116 * data.c: Avoid integer truncation in expressions involving floats.
16117 * data.c: Include <intprops.h>.
16118 (arith_driver): When there's an integer overflow in an expression
16119 involving floating point, convert the integers to floating point
16120 so that the resulting value does not suffer from catastrophic
16121 integer truncation. For example, on a 64-bit host (* 4
16122 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
16123 Do not rely on undefined behavior after integer overflow.
16125 merge count_size_as_multibyte, parse_str_to_multibyte
16126 * character.c, character.h (count_size_as_multibyte):
16127 Rename from parse_str_to_multibyte; all uses changed.
16128 Check for integer overflow.
16129 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
16130 since it's now a duplicate of the other. This is more of
16131 a character than a buffer op, so better that it's in character.c.
16132 * fns.c, print.c: Adjust to above changes.
16134 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
16136 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
16138 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
16140 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
16141 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
16142 (x_clipboard_manager_save): Now static.
16143 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
16145 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
16146 (crypto_hash_function): Now static.
16147 Fix pointer signedness problems. Avoid unnecessary initializations.
16149 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
16151 * termhooks.h (Vselection_alist): Make it terminal-local.
16153 * terminal.c (create_terminal): Initialize it.
16155 * xselect.c: Support for clipboard managers.
16156 (Vselection_alist): Move to termhooks.h as terminal-local var.
16157 (LOCAL_SELECTION): New macro.
16158 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
16159 (symbol_to_x_atom): Remove gratuitous arg.
16160 (x_handle_selection_request, lisp_data_to_selection_data)
16161 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
16162 (x_own_selection, x_get_local_selection, x_convert_selection):
16163 New arg, specifying work frame. Use terminal-local Vselection_alist.
16164 (some_frame_on_display): Delete unused function.
16165 (Fx_own_selection_internal, Fx_get_selection_internal)
16166 (Fx_disown_selection_internal, Fx_selection_owner_p)
16167 (Fx_selection_exists_p): New optional frame arg.
16168 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
16169 (x_handle_selection_clear): Don't treat other terminals with the
16170 same keyboard specially. Use the terminal-local Vselection_alist.
16171 (x_clear_frame_selections): Use Frun_hook_with_args.
16173 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
16175 * xterm.h: Add support for those atoms.
16177 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
16179 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
16180 (converted_selections, conversion_fail_tag): New global variables.
16181 (x_selection_request_lisp_error): Free the above.
16182 (x_get_local_selection): Remove unnecessary code.
16183 (x_reply_selection_request): Args changed; handle arbitrary array
16184 of converted selections stored in converted_selections.
16185 Separate the XChangeProperty and SelectionNotify steps.
16186 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
16187 (x_convert_selection): New function.
16188 (x_handle_selection_event): Simplify.
16189 (x_get_foreign_selection): Don't ignore incoming requests while
16190 waiting for an answer; this will fail when we implement
16191 SAVE_TARGETS, and seems unnecessary anyway.
16192 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
16193 (Vx_sent_selection_functions): Doc fix.
16195 2011-05-26 Leo Liu <sdl.web@gmail.com>
16197 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
16199 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16201 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
16203 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
16204 for fringe update if it has periodic bitmap.
16205 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
16206 and fringe_bitmap_periodic_p.
16208 * fringe.c (get_fringe_bitmap_data): New function.
16209 (draw_fringe_bitmap_1, update_window_fringes): Use it.
16210 (update_window_fringes): Record periodicity of fringe bitmap in glyph
16211 row. Mark glyph row for fringe update if periodicity changed.
16213 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
16214 for fringe update unless it has periodic bitmap.
16216 2011-05-25 Kenichi Handa <handa@m17n.org>
16218 * xdisp.c (get_next_display_element): Set correct it->face_id for
16219 a static composition.
16221 2011-05-24 Leo Liu <sdl.web@gmail.com>
16224 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
16226 * fns.c (crypto_hash_function, Fsha1): New function.
16227 (Fmd5): Use crypto_hash_function.
16228 (syms_of_fns): Add Ssha1.
16230 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
16232 * gnutls.c: Remove unused macros.
16233 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
16234 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
16235 Remove macros that are defined and never used.
16236 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
16238 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
16240 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
16241 (Fx_get_selection_internal): Minor cleanup.
16242 (Fx_own_selection_internal): Rename arguments for consistency with
16245 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
16247 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
16249 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
16251 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
16253 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16255 * dispnew.c (scrolling_window): Don't exclude the case that the
16256 last enabled row in the desired matrix touches the bottom boundary.
16258 2011-05-21 Glenn Morris <rgm@gnu.org>
16260 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
16261 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
16262 and add some more files.
16264 2011-05-20 Eli Zaretskii <eliz@gnu.org>
16266 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
16267 report_file_error introduced by the change from 2011-05-07.
16269 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
16271 * systime.h (Time): Define only if emacs is defined.
16272 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
16273 where the include path doesn't have X11/X.h by default. See
16274 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
16276 2011-05-20 Kenichi Handa <handa@m17n.org>
16278 * composite.c (find_automatic_composition): Fix previous change.
16280 2011-05-20 Glenn Morris <rgm@gnu.org>
16282 * lisp.mk: New file, split from Makefile.in.
16283 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
16284 (shortlisp): Remove.
16285 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
16287 2011-05-19 Glenn Morris <rgm@gnu.org>
16289 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
16290 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
16291 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
16292 (lisp): Set the order to that of loadup.el.
16293 (shortlisp): Make it a copy of $lisp.
16294 (SOME_MACHINE_LISP): Remove.
16295 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
16296 Use just $shortlisp, not $SOME_MACHINE_LISP too.
16298 2011-05-18 Kenichi Handa <handa@m17n.org>
16300 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
16301 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
16302 (find_automatic_composition): Mostly rewrite for efficiency.
16304 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
16306 * makefile.w32-in: Update dependencies.
16308 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
16310 * menu.c: Include limits.h (fixes the MS-Windows build broken by
16311 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
16313 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
16315 Fix some integer overflow issues, such as string length overflow.
16317 * insdel.c (count_size_as_multibyte): Check for string overflow.
16319 * character.c (lisp_string_width): Check for string overflow.
16320 Use EMACS_INT, not int, for string indexes and lengths; in
16321 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
16322 the resulting string length overflows an EMACS_INT; instead,
16323 report a string overflow if no precision given. When checking for
16324 precision exhaustion, use a check that cannot possibly have
16325 integer overflow. (Bug#8675)
16326 * character.h (lisp_string_width): Adjust to new signature.
16328 * alloc.c (string_overflow): New function.
16329 (Fmake_string): Use it. This doesn't change behavior, but saves
16330 a few bytes and will simplify future changes.
16331 * character.c (string_escape_byte8): Likewise.
16332 * lisp.h (string_overflow): New decl.
16334 Fixups, following up to the user-interface timestamp change.
16335 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
16336 for UI timestamps, instead of unsigned long.
16337 * msdos.c (mouse_get_pos): Likewise.
16338 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
16339 * w32gui.h (Time): Define by including "systime.h" rather than by
16340 declaring it ourselves. (Bug#8664)
16342 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
16343 * image.c (clear_image_cache): Likewise.
16345 * term.c (term_mouse_position): Don't assume time_t wraparound.
16347 Be more systematic about user-interface timestamps.
16348 Before, the code sometimes used 'Time', sometimes 'unsigned long',
16349 and sometimes 'EMACS_UINT', to represent these timestamps.
16350 This change causes it to use 'Time' uniformly, as that's what X uses.
16351 This makes the code easier to follow, and makes it easier to catch
16352 integer overflow bugs such as Bug#8664.
16353 * frame.c (Fmouse_position, Fmouse_pixel_position):
16354 Use Time, not unsigned long, for user-interface timestamps.
16355 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
16356 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
16357 * keyboard.h (last_event_timestamp): Likewise.
16358 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
16359 * menu.h (xmenu_show): Likewise.
16360 * term.c (term_mouse_position): Likewise.
16361 * termhooks.h (struct input_event.timestamp): Likewise.
16362 (struct terminal.mouse_position_hook): Likewise.
16363 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
16364 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
16365 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
16366 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
16367 what it was before.
16368 * menu.h, termhooks.h: Include "systime.h", for Time.
16370 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
16371 Don't assume that the difference between two unsigned long values
16372 can fit into an integer. At this point, we know button_down_time
16373 <= event->timestamp, so the difference must be nonnegative, so
16374 there's no need to cast the result if double-click-time is
16375 nonnegative, as it should be; check that it's nonnegative, just in
16376 case. This bug is triggered when events are more than 2**31 ms
16377 apart (about 25 days). (Bug#8664)
16379 * xselect.c (last_event_timestamp): Remove duplicate decl.
16380 (x_own_selection): Remove needless cast to unsigned long.
16382 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
16383 that always fit in int. Use a sentinel instead of a counter, to
16384 avoid a temp and to allay GCC's concerns about possible int overflow.
16385 * frame.h (struct frame): Use int for menu_bar_items_used
16386 instead of EMACS_INT, since it always fits in int.
16388 * menu.c (grow_menu_items): Check for int overflow.
16390 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
16392 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
16393 Before, the code was not consistent. These values cannot exceed
16394 2**31 - 1 so there's no need to make them unsigned.
16395 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
16396 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
16397 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
16399 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
16401 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
16402 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
16403 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
16404 presumably because the widths might not match.
16406 * window.c (size_window): Avoid needless test at loop start.
16408 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
16410 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
16412 2011-05-12 Drew Adams <drew.adams@oracle.com>
16414 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
16416 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16418 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
16419 `width' to `bar_area_x' and `bar_area_width', respectively.
16420 (x_scroll_run): Take account of fringe background extension.
16422 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
16423 Rename local vars `left' and `width' to `bar_area_x' and
16424 `bar_area_width', respectively.
16425 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
16426 background extension.
16428 2011-05-10 Jim Meyering <meyering@redhat.com>
16430 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
16432 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
16434 * image.c (Finit_image_library): Return t for built-in image types,
16435 like pbm and xbm. (Bug#8640)
16437 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
16439 * w32menu.c (set_frame_menubar): Fix submenu allocation.
16441 2011-05-07 Eli Zaretskii <eliz@gnu.org>
16443 * w32console.c (Fset_screen_color): Doc fix.
16444 (Fget_screen_color): New function.
16445 (syms_of_ntterm): Defsubr it.
16447 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
16448 unlink the temporary file if Fcall_process didn't create it in the
16450 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
16451 child process will be redirected to a file specified with `:file'.
16452 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
16453 cue to call_process_cleanup not to close that handle.
16455 2011-05-07 Ben Key <bkey76@gmail.com>
16457 * makefile.w32-in: The bootstrap-temacs rule now makes use of
16458 one of two shell specific rules, either bootstrap-temacs-CMD or
16459 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
16460 to the previous implementation of the bootstrap-temacs rule.
16461 The bootstrap-temacs-CMD rule is similar to the previous
16462 implementation of the bootstrap-temacs rule except that it
16463 makes use of the ESC_CFLAGS variable instead of the CFLAGS
16466 These changes, along with some changes to nt/configure.bat,
16467 nt/gmake.defs, and nt/nmake.defs, are required to extend my
16468 earlier fix to add support for --cflags and --ldflags options
16469 that include quotes so that it works whether make uses cmd or
16472 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
16474 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
16475 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
16477 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
16478 a string. Handle both cases.
16479 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
16480 (Fdbus_register_method): Use Qinvalid_function.
16482 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
16484 * makefile.w32-in: Update dependencies.
16485 (LISP_H): Add inttypes.h and stdin.h.
16486 (PROCESS_H): Add unistd.h.
16488 2011-05-06 Eli Zaretskii <eliz@gnu.org>
16490 * lread.c: Include limits.h (fixes the MS-Windows build broken by
16491 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
16493 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
16495 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
16497 * term.c (vfatal): Remove stray call to va_end.
16498 It's not needed and the C Standard doesn't allow it here anyway.
16500 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
16501 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
16503 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
16506 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
16508 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16510 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
16512 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
16514 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
16516 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
16517 * charset.c (Fdefine_charset_internal): Don't initialize
16518 charset.code_space[15]. The value was garbage, on hosts with
16519 32-bit int (Bug#8600).
16521 * lread.c (read_integer): Be more consistent with string-to-number.
16522 Use string_to_number to do the actual conversion; this avoids
16523 rounding errors and fixes some other screwups. Without this fix,
16524 for example, #x1fffffffffffffff was misread as -2305843009213693952.
16525 (digit_to_number): Move earlier, for benefit of read_integer.
16526 Return -1 if the digit is out of range for the base, -2 if it is
16527 not a digit in any supported base. (Bug#8602)
16529 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
16531 * dispnew.c (scrolling_window): Return 1 if we scrolled,
16532 to match comment at start of function. This also removes a
16533 GCC warning about overflow in a 32+64-bit port.
16535 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
16537 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
16538 Reported by Stefan Monnier in
16539 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
16540 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
16541 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
16543 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
16544 (EMACS_UINTPTR): Likewise, with uintptr_t.
16546 * lisp.h: Prefer 64-bit EMACS_INT if available.
16547 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
16548 on 32-bit hosts that have 64-bit int, so that they can access
16550 However, temporarily disable this change unless the temporary
16551 symbol WIDE_EMACS_INT is defined.
16553 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
16555 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
16556 This removes an assumption that EMACS_INT and long are the same
16557 width as pointers. The assumption is true for Emacs porting targets
16558 now, but we want to make other targets possible.
16559 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
16560 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
16561 In the rest of the code, change types of integers that hold casted
16562 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
16563 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
16564 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
16565 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
16566 No need to cast type when ORing.
16567 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
16568 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
16569 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
16570 assume EMACS_INT is the same width as char *.
16571 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
16572 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
16573 Remove no-longer-needed casts.
16574 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
16575 (xg_tool_bar_help_callback, xg_make_tool_item):
16576 Use EMACS_INTPTR to hold an integer
16577 that will be cast to void *; this can avoid a GCC warning
16578 if EMACS_INT is not the same width as void *.
16579 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
16580 * xdisp.c (display_echo_area_1, resize_mini_window_1):
16581 (current_message_1, set_message_1):
16582 Use a local to convert to proper width without a cast.
16583 * xmenu.c (dialog_selection_callback): Likewise.
16585 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
16586 Also, don't assume VALBITS / RAND_BITS is less than 5,
16587 and don't rely on undefined behavior when shifting a 1 left into
16589 * lisp.h (get_random): Change signature to match.
16591 * lread.c (hash_string): Use size_t, not int, for hash computation.
16592 Normally we prefer signed values; but hashing is special, because
16593 it's better to use unsigned division on hash table sizes so that
16594 the remainder is nonnegative. Also, size_t is the natural width
16595 for hashing into memory. The previous code used 'int', which doesn't
16596 retain enough info to hash well into very large tables.
16597 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
16599 * dbusbind.c: Don't possibly lose pointer info when converting.
16600 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
16601 Use XPNTR rather than XHASH, so that the high-order bits of
16602 the pointer aren't lost when converting through void *.
16604 * eval.c (Fautoload): Don't double-shift a pointer.
16606 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
16608 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
16610 * gnutls.c (DEF_GNUTLS_FN):
16611 * image.c (DEF_IMGLIB_FN): Make function pointers static.
16613 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
16615 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
16618 2011-05-05 Eli Zaretskii <eliz@gnu.org>
16620 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:

16629 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
16630 `gnutls_certificate_set_x509_key_file'.
16632 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
16634 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
16635 Update dependencies.
16637 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
16639 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
16640 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
16641 Remove unused parameter `fildes'.
16642 * process.c (read_process_output, send_process): Don't pass it.
16644 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
16646 Fix previous change: the library cache is defined in w32.c.
16647 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
16648 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".

16652 Implement dynamic loading of GnuTLS on Windows.
16654 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
16655 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
16656 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
16659 * gnutls.c (Qgnutls_dll): Define.

16669 (Fgnutls_available_p): New function.
16670 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

16682 * w32.c (QCloaded_from, Vlibrary_cache): Define.
16683 (w32_delayed_load): Move from image.c. When loading a library, record
16684 its filename in the :loaded-from property of the library id.
16685 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
16686 Initialize and staticpro them.
16687 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
16689 * process.c: Include lisp.h before w32.h, not after.
16690 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
16691 instead of gnutls_record_check_pending.
16693 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
16695 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
16697 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
16698 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
16701 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
16703 * xterm.c (x_set_frame_alpha): Do not set property on anything
16704 else than FRAME_X_OUTER_WINDOW (Bug#8608).
16706 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
16708 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
16710 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
16712 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

16738 (Fcall_process_region): Ditto.
16740 2011-04-30 Eli Zaretskii <eliz@gnu.org>
16742 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
16743 rather than `XVECTOR (FOO)->size'.
16745 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
16746 inttypes.h, as a gnulib replacement is used if it not available in
16749 2011-04-21 Eli Zaretskii <eliz@gnu.org>
16751 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
16752 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
16753 of MOST_POSITIVE_FIXNUM. (Bug#8528)
16755 * coding.c (coding_alloc_by_realloc): Error out if destination
16756 will grow beyond MOST_POSITIVE_FIXNUM.
16757 (decode_coding_emacs_mule): Abort if there isn't enough place in
16758 charbuf for the composition carryover bytes. Reserve an extra
16759 space for up to 2 characters produced in a loop.
16760 (decode_coding_iso_2022): Abort if there isn't enough place in
16761 charbuf for the composition carryover bytes.
16763 2011-04-21 Eli Zaretskii <eliz@gnu.org>
16765 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
16766 aborting when %lld or %lll format is passed.
16767 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
16768 %llo or %llx format is passed. (Bug#8545)
16770 * window.c (window_scroll_line_based): Use a marker instead of
16771 simple variables to record original value of point. (Bug#7952)
16773 * doprnt.c (doprnt): Fix the case where a multibyte sequence
16774 produced by %s or %c overflows available buffer space. (Bug#8545)
16776 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
16778 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

16787 * keyboard.c (Qdelayed_warnings_hook): Define.
16788 (command_loop_1): Run `delayed-warnings-hook'
16789 if Vdelayed_warnings_list is non-nil.
16790 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
16791 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
16793 2011-04-28 Eli Zaretskii <eliz@gnu.org>
16795 * doprnt.c (doprnt): Don't return value smaller than the buffer
16796 size if the message was truncated. (Bug#8545).
16798 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
16800 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
16801 (Fx_window_property): #if-0 the whole functions, not just the bodies.
16803 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
16805 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
16807 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
16809 * makefile.w32-in: Update dependencies.
16811 2011-04-27 Eli Zaretskii <eliz@gnu.org>
16813 Improve `doprnt' and its usage. (Bug#8545)
16814 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
16815 `format_end'. Remove support for %l as a conversion specifier.
16816 Don't use xrealloc. Improve diagnostics when the %l size modifier
16817 is used. Update the commentary.
16819 * eval.c (verror): Simplify calculation of size_t.
16821 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
16824 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
16826 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
16829 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
16831 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
16832 This makes this file independent of the recent pseudovector change.
16834 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
16836 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
16838 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
16839 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
16840 Remove unused local.
16841 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
16843 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
16844 GCC 4.6.0 optimizes based on type-based alias analysis.
16845 For example, if b is of type struct buffer * and v of type struct
16846 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
16847 != &v->size, and therefore "v->size = 1; b->size = 2; return
16848 v->size;" must therefore return 1. This assumption is incorrect
16849 for Emacs, since it type-puns struct Lisp_Vector * with many other
16850 types. To fix this problem, this patch adds a new type struct
16851 vectorlike_header that documents the constraints on layout of vectors
16852 and pseudovectors, and helps optimizing compilers not get fooled
16853 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
16854 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
16855 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
16857 (XSETPVECTYPE): Rewrite in terms of new macro.
16858 (XSETPVECTYPESIZE): New macro, specifying both type and size.
16859 This is a bit clearer, and further avoids the possibility of
16860 undesirable aliasing.
16861 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
16862 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
16863 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
16864 since Lisp_Subr is a special case (no "next" field).
16865 (ASIZE): Now uses header.size rather than size.
16866 All previous uses of XVECTOR (foo)->size replaced to use this macro,
16867 to avoid the hassle of writing XVECTOR (foo)->header.size.
16868 (struct vectorlike_header): New type.
16869 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
16870 object, to help avoid aliasing.
16871 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
16872 (SUBRP): Likewise, since Lisp_Subr is a special case.
16873 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
16874 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
16875 (struct Lisp_Hash_Table): Combine first two members into a single
16876 struct vectorlike_header member. All uses of "size" and "next" members
16877 changed to be "header.size" and "header.next".
16878 * buffer.h (struct buffer): Likewise.
16879 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
16880 * frame.h (struct frame): Likewise.
16881 * process.h (struct Lisp_Process): Likewise.
16882 * termhooks.h (struct terminal): Likewise.
16883 * window.c (struct save_window_data, struct saved_window): Likewise.
16884 * window.h (struct window): Likewise.
16885 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
16886 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
16887 * buffer.c (init_buffer_once): Likewise.
16888 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
16890 * process.c (Fformat_network_address): Use local var for size,
16893 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
16895 Make the Lisp reader and string-to-float more consistent (Bug#8525)
16896 * data.c (atof): Remove decl; no longer used or needed.
16897 (digit_to_number): Move to lread.c.
16898 (Fstring_to_number): Use new string_to_number function, to be
16899 consistent with how the Lisp reader treats infinities and NaNs.
16900 Do not assume that floating-point numbers represent EMACS_INT
16901 without losing information; this is not true on most 64-bit hosts.
16902 Avoid double-rounding errors, by insisting on integers when
16903 parsing non-base-10 numbers, as the documentation specifies.
16904 * lisp.h (string_to_number): New decl, replacing ...
16905 (isfloat_string): Remove.
16906 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
16907 (read1): Do not accept +. and -. as integers; this
16908 appears to have been a coding error. Similarly, do not accept
16909 strings like +-1e0 as floating point numbers. Do not report
16910 overflow for integer overflows unless the base is not 10 which
16911 means we have no simple and reliable way to continue.
16912 Break out the floating-point parsing into a new
16913 function string_to_number, so that Fstring_to_number parses
16914 floating point numbers consistently with the Lisp reader.
16915 (digit_to_number): Move here from data.c. Make it static inline.
16916 (E_CHAR, EXP_INT): Remove, replacing with ...
16917 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
16918 (string_to_number): New function, replacing isfloat_string.
16919 This function checks for valid syntax and produces the resulting
16920 Lisp float number too. Rework it so that string-to-number
16921 no longer mishandles examples like "1.0e+". Use strtoumax,
16922 so that overflow for non-base-10 numbers is reported only when
16923 there's no portable and simple way to convert to floating point.
16925 * textprop.c (set_text_properties_1): Rewrite for clarity,
16926 and to avoid GCC warning about integer overflow.
16928 * intervals.h (struct interval): Use EMACS_INT for members
16929 where EMACS_UINT might cause problems. See
16930 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
16931 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
16932 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
16934 (offset_intervals): Tell GCC not to worry about length overflow
16935 when negating a negative length.
16937 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
16938 (overrun_check_free): Likewise.
16940 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
16941 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
16944 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
16945 (gnutls_make_error): Rename local to avoid shadowing.
16946 (gnutls_emacs_global_deinit): ifdef out; not used.
16947 (Fgnutls_boot): Use const for pointer to readonly storage.
16948 Comment out unused local. Fix pointer signedness problems.
16950 * lread.c (openp): Don't stuff size_t into an 'int'.
16951 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
16952 about possible signed overflow.
16954 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
16955 (GDK_KEY_g): Don't define if already defined.
16956 (xg_prepare_tooltip): Avoid pointer signedness problem.
16957 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
16959 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
16960 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
16962 * xfns.c (Fx_window_property): Simplify a bit,
16963 to make a bit faster and to avoid GCC 4.6.0 warning.
16964 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
16966 * fns.c (internal_equal): Don't assume size_t fits in int.
16968 * alloc.c (compact_small_strings): Tighten assertion a little.
16970 Replace pEd with more-general pI, and fix some printf arg casts.
16971 * lisp.h (pI): New macro, generalizing old pEd macro to other
16972 conversion specifiers. For example, use "...%"pI"d..." rather
16973 than "...%"pEd"...".
16974 (pEd): Remove. All uses replaced with similar uses of pI.
16975 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
16976 * alloc.c (check_pure_size): Don't overflow by converting size to int.
16977 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
16978 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
16979 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
16980 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
16981 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
16983 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
16984 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
16985 * print.c (safe_debug_print, print_object): Likewise.
16986 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
16988 Use pI instead of if-then-else-abort. Use %p to avoid casts,
16989 avoiding the 0 flag, which is not portable.
16990 * process.c (Fmake_network_process): Use pI to avoid cast.
16991 * region-cache.c (pp_cache): Likewise.
16992 * xdisp.c (decode_mode_spec): Likewise.
16993 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
16994 behavior on 64-bit hosts with printf arg.
16995 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
16996 (x_stop_queuing_selection_requests): Likewise.
16997 (x_get_window_property): Don't truncate byte count to an 'int'
17000 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
17001 here, since it parses constructs like leading '-' and spaces,
17002 which are not wanted; and it overflows with large numbers.
17003 Instead, simply match F[0-9]+, which is what is wanted anyway.
17005 * alloc.c: Remove unportable assumptions about struct layout.
17006 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
17007 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
17008 (allocate_vectorlike, make_pure_vector): Use the new macros,
17009 plus offsetof, to remove unportable assumptions about struct layout.
17010 These assumptions hold on all porting targets that I know of, but
17011 they are not guaranteed, they're easy to remove, and removing them
17012 makes further changes easier.
17014 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
17015 This doesn't fix a bug but makes the code clearer.
17016 (string_overrun_cookie): Now const. Use initializers that
17017 don't formally overflow signed char, to avoid warnings.
17018 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
17019 can cause Emacs to crash when string overrun checking is enabled.
17020 (allocate_buffer): Don't assume sizeof (struct buffer) is a
17021 multiple of sizeof (EMACS_INT); it need not be, if
17022 alignof(EMACS_INT) < sizeof (EMACS_INT).
17023 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
17025 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

17052 2011-04-25 Eli Zaretskii <eliz@gnu.org>
17054 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
17055 "cast to pointer from integer of different size".
17057 Improve doprnt and its use in verror. (Bug#8545)
17058 * doprnt.c (doprnt): Document the set of format control sequences
17059 supported by the function. Use SAFE_ALLOCA instead of always
17062 * eval.c (verror): Don't limit the buffer size at size_max-1, that
17063 is one byte too soon. Don't use xrealloc; instead xfree and
17066 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
17068 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the

17072 gnutls_global_initialized. Added internals for the
17073 :verify-hostname-error, :verify-error, and :verify-flags
17074 parameters of `gnutls-boot' and documented those parameters in the
17075 docstring. Start callback support.
17076 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
17077 unless a fatal error occurred. Call gnutls_alert_send_appropriate

17175 * callint.c (Fcall_interactively): When displaying error message
17176 about invalid control letter, pass the character's codepoint, not

17181 codepoint of an invalid character, to avoid displaying a bogus
17184 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
17185 `error', not SYMBOL_NAME itself.
17187 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for

17190 * charset.c (check_iso_charset_parameter): Fix incorrect argument
17191 to `error' in error message about FINAL_CHAR argument. Make sure
17192 FINAL_CHAR is a character, and use %c when it is passed as
17193 argument to `error'.
17195 2011-04-23 Eli Zaretskii <eliz@gnu.org>
17197 * s/ms-w32.h (localtime): Redirect to sys_localtime.
17199 * w32.c: Include <time.h>.

17259 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
17260 by pacifying GCC about it. Maybe it's time to retire it?
17261 * xfaces.c (USG, __TIMEVAL__): Likewise.
17263 * dispextern.h (struct redisplay_interface): Rename param
17264 to avoid shadowing.
17265 * termhooks.h (struct terminal): Likewise.
17266 * xterm.c (xembed_send_message): Likewise.

17382 * nsfont.m: Fixed bugs in ns_get_family and
17383 ns_descriptor_to_entity that were caused by using free to
17384 deallocate memory blocks that were allocated by xmalloc (via
17385 xstrdup). This caused Emacs to crash when compiled with
17386 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
17387 --enable-checking=xmallocoverrun). xfree is now used to
17388 deallocate these memory blocks.
17390 2011-04-15 Paul Eggert <eggert@cs.ucla.edu>
17392 * sysdep.c (emacs_read): Remove unnecessary check vs MAX_RW_COUNT.

17402 (emacs_read, emacs_write): Remove check for negative size, as the
17403 Emacs source code has been audited now.
17404 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
17405 (emacs_read, emacs_write): Use it.
17406 * process.c (send_process): Adjust to the new signatures of
17407 emacs_write and emacs_gnutls_write. Do not attempt to store
17408 a byte offset into an 'int'; it might overflow.
17409 See http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00483.html

17834 * keyboard.c (Fthis_command_keys): Remove decl.
17835 (Fcommand_execute): New forward static decl.
17836 * keymap.c (Flookup_key): New forward static decl.
17837 (Fcopy_keymap): Now static.
17838 * keymap.h (Flookup_key): Remove decl.
17839 * process.c (Fget_process): New forward static decl.
17840 (Fprocess_datagram_address): Mark as internal.
17841 * syntax.c (Fsyntax_table_p): New forward static decl.

17856 2011-04-13 Eli Zaretskii <eliz@gnu.org>
17858 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
17859 when at ZV. (Bug#8487)
17861 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
17863 * charset.c (Fclear_charset_maps): Use xfree instead of free.
17865 * keyboard.c (parse_tool_bar_item): Likewise.
17866 * sound.c (sound_cleanup, alsa_close): Likewise.
17867 * termcap.c (tgetent): Likewise.
17868 * xfns.c (x_default_font_parameter): Likewise.
17869 * xsettings.c (read_and_apply_settings): Likewise.
17871 * alloc.c (overrun_check_malloc, overrun_check_realloc)
17872 (overrun_check_free): Protoize.
17874 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
17876 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
17877 since callers should never pass a negative size.
17878 Change the signature to match that of plain 'read' and 'write'; see
17879 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
17880 * lisp.h: Update prototypes of emacs_write and emacs_read.
17882 2011-04-11 Eli Zaretskii <eliz@gnu.org>
17884 * xdisp.c (redisplay_window): Don't try to determine the character
17885 position of the scroll margin if the window start point w->startp
17886 is outside the buffer's accessible region. (Bug#8468)
17888 2011-04-10 Eli Zaretskii <eliz@gnu.org>
17890 Fix write-region and its subroutines for buffers > 2GB.
17891 * fileio.c (a_write, e_write): Modify declaration of arguments and
17892 local variables to support buffers larger than 2GB.
17893 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
17895 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
17896 argument, local variables, and return value.
17898 * lisp.h: Update prototypes of emacs_write and emacs_read.
17900 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
17902 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
17904 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
17906 Fix more problems found by GCC 4.6.0's static checks.
17908 * xdisp.c (vmessage): Use a better test for character truncation.
17910 * charset.c (load_charset_map): <, not <=, for optimization,
17911 and to avoid potential problems with integer overflow.
17912 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
17913 * casetab.c (set_identity, shuffle): Likewise.
17914 * editfns.c (Fformat): Likewise.
17915 * syntax.c (skip_chars): Likewise.
17917 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
17918 This also lets GCC 4.6.0 generate slightly better loop code.
17920 * callint.c (Fcall_interactively): <, not <=, for optimization.
17921 (Fcall_interactively): Count the number of arguments produced,
17922 not the number of arguments given. This is simpler and lets GCC
17923 4.6.0 generate slightly better code.
17925 * ftfont.c: Distingish more carefully between FcChar8 and char.
17926 The previous code passed unsigned char * to a functions like
17927 strlen and xstrcasecmp that expect char *, which does not
17928 conform to the C standard.
17929 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
17930 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
17931 char * when the C standard requires it.
17933 * keyboard.c (read_char): Remove unused var.
17935 * eval.c: Port to Windows vsnprintf (Bug#8435).
17936 Include <limits.h>.
17937 (SIZE_MAX): Define if the headers do not.
17938 (verror): Do not give up if vsnprintf returns a negative count.
17939 Instead, grow the buffer. This ports to Windows vsnprintf, which
17940 does not conform to C99. Problem reported by Eli Zaretskii.
17941 Also, simplify the allocation scheme, by avoiding the need for
17942 calling realloc, and removing the ALLOCATED variable.
17944 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
17946 Remove invocations of doprnt, as Emacs now uses vsnprintf.
17947 But keep the doprint source code for now, as we might revamp it
17948 and use it again (Bug#8435).
17949 * lisp.h (doprnt): Remove.
17950 * Makefile.in (base_obj): Remove doprnt.o.
17951 * deps.mk (doprnt.o): Remove.
17953 error: Print 32- and 64-bit integers portably (Bug#8435).
17954 Without this change, on typical 64-bit hosts error ("...%d...", N)
17955 was used to print both 32- and 64-bit integers N, which relied on
17956 undefined behavior.
17957 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
17958 * lisp.h (error, verror): Mark as printf-like functions.
17959 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
17960 Report overflow in size calculations when allocating printf buffer.
17961 Do not truncate output string at its first null byte.
17962 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
17963 Truncate the output at a character boundary, since vsnprintf does not
17965 * charset.c (check_iso_charset_parameter): Convert internal
17966 character to string before calling 'error', since %c now has the
17968 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
17969 overflow when computing char to be passed to 'error'. Do not
17970 pass Lisp_Object to 'error'; pass the integer instead.
17971 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
17972 formatted with plain %d.
17974 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
17976 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
17978 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
17980 * xterm.c (x_catch_errors): Remove duplicate declaration.
17982 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
17984 * xdisp.c, lisp.h (message_nolog): Remove; unused.
17986 2011-04-10 Jim Meyering <meyering@redhat.com>
17988 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
17989 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
17990 return ssize_t not "int", and use size_t as the buffer length.
17991 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
17992 * gnutls.h: Update declarations.
17993 * process.c (read_process_output): Use ssize_t, to match.
17994 (send_process): Likewise.
17996 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
17998 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
18000 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
18002 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
18003 Use unsigned char, to match FcChar8 type definition.
18005 * xterm.c (handle_one_xevent):
18006 * xmenu.c (create_and_show_popup_menu):
18007 * xselect.c (x_decline_selection_request)
18008 (x_reply_selection_request): Avoid type-punned deref of X events.
18010 2011-04-09 Eli Zaretskii <eliz@gnu.org>
18012 Fix some uses of `int' instead of EMACS_INT.
18013 * search.c (string_match_1, fast_string_match)
18014 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
18015 (scan_buffer, find_next_newline_no_quit)
18016 (find_before_next_newline, search_command, Freplace_match)
18017 (Fmatch_data): Make some `int' variables be EMACS_INT.
18019 * xdisp.c (display_count_lines): 3rd argument and return value now
18020 EMACS_INT. All callers changed.
18021 (pint2hrstr): Last argument is now EMACS_INT.
18023 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
18024 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
18025 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
18026 (decode_coding_utf_16, decode_coding_emacs_mule)
18027 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
18028 (decode_coding_ccl, decode_coding_charset)
18029 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
18030 (decode_coding_iso_2022, decode_coding_emacs_mule)
18031 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
18032 <char_offset, last_offset>: Declare EMACS_INT.
18033 (encode_coding_utf_8, encode_coding_utf_16)
18034 (encode_coding_emacs_mule, encode_invocation_designation)
18035 (encode_designation_at_bol, encode_coding_iso_2022)
18036 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
18037 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
18039 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
18040 (encode_invocation_designation): Last argument P_NCHARS is now
18042 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
18043 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
18045 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
18048 * ccl.c (Fccl_execute_on_string): Declare some variables
18051 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
18053 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
18055 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
18057 * process.c (Fformat_network_address): Doc fix.
18059 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
18061 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
18063 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
18065 * keyboard.c (read_char): Call Lisp function help-form-show,
18066 instead of using internal_with_output_to_temp_buffer.
18067 (Qhelp_form_show): New var.
18068 (syms_of_keyboard): Use DEFSYM macro.
18070 * print.c (internal_with_output_to_temp_buffer): Function deleted.
18072 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
18074 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
18076 * process.c (Flist_processes): Remove to Lisp.
18077 (list_processes_1): Delete.
18079 2011-04-06 Eli Zaretskii <eliz@gnu.org>
18081 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
18083 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
18085 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
18087 Fix more problems found by GCC 4.6.0's static checks.
18089 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
18091 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
18093 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
18095 * xdisp.c (vmessage): Mark as a printf-like function.
18097 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
18099 * sound.c (sound_warning): Don't crash if arg contains a printf format.
18101 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
18102 printf-like functions.
18103 (tiff_load): Add casts to remove these marks before passing them
18104 to system-supplied API.
18106 * eval.c (Fsignal): Remove excess argument to 'fatal'.
18108 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
18109 This avoids several warnings with gcc -Wstrict-overflow.
18110 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
18111 directly, rather than having caller test rule sign. This avoids
18112 some unnecessary tests.
18113 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
18114 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
18115 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
18117 * xfont.c (xfont_text_extents): Remove var that was set but not used.
18118 (xfont_open): Avoid unnecessary tests.
18120 * composite.c (composition_gstring_put_cache): Use unsigned integer.
18122 * composite.h, composite.c (composition_gstring_put_cache):
18123 Use EMACS_INT, not int, for length.
18125 * composite.h (COMPOSITION_DECODE_REFS): New macro,
18126 breaking out part of COMPOSITION_DECODE_RULE.
18127 (COMPOSITION_DECODE_RULE): Use it.
18128 * composite.c (get_composition_id): Remove unused local vars,
18129 by using the new macro.
18131 * textprop.c (set_text_properties_1): Change while to do-while,
18132 since the condition is always true at first.
18134 * intervals.c (graft_intervals_into_buffer): Mark var as used.
18135 (interval_deletion_adjustment): Return unsigned value.
18138 * process.c (list_processes_1, create_pty, read_process_output):

18148 (update_syntax_table): Use unsigned instead of int.
18150 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
18151 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
18152 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
18154 * print.c (print_error_message): Avoid int overflow.
18156 * font.c (font_list_entities): Redo for clarity,
18157 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
18159 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
18160 (font_score): Avoid potential overflow in diff calculation.
18162 * fns.c (substring_both): Remove var that is set but not used.
18163 (sxhash): Redo loop for clarity and to avoid wraparound warning.
18165 * eval.c (funcall_lambda): Rename local to avoid shadowing.
18167 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
18168 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
18169 can always succeed if overflow has undefined behavior.
18171 * search.c (boyer_moore, wordify): Remove vars set but not used.
18172 (wordify): Omit three unnecessary tests.
18174 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
18175 All callers changed. This avoids the need for an unused var.
18177 * casefiddle.c (casify_region): Remove var that is set but not used.
18179 * dired.c (file_name_completion): Remove var that is set but not used.
18181 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
18183 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
18184 (Finsert_file_contents): Remove unnecessary code checking fd.
18186 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
18187 Check for integer overflow on size calculations.
18189 * buffer.c (Fprevious_overlay_change): Remove var that is set
18192 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
18193 Remove vars that are set but not used.
18194 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
18195 (timer_check_2): Mark vars as initialized.
18197 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
18199 * image.c (lookup_image): Remove var that is set but not used.
18200 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
18202 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
18203 that are set but not used.
18205 * xfns.c (make_invisible_cursor): Don't return garbage
18206 if XCreateBitmapFromData fails (Bug#8410).
18208 * xselect.c (x_get_local_selection, x_handle_property_notify):
18209 Remove vars that are set but not used.
18211 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
18212 (make_invisible_cursor): Initialize a possibly-uninitialized variable.

18217 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
18218 Check for overflow.

18221 (map_tty_color) [!defined MSDOS]: Likewise.
18223 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
18225 * coding.c: Remove vars that are set but not used.
18226 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
18227 All callers changed.
18228 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
18229 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
18230 (decode_coding_charset): Remove vars that are set but not used.
18232 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
18233 that is set but not used.
18235 * print.c (print_object): Remove var that is set but not used.
18237 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
18238 The gnulib version avoids calling malloc in the usual case,
18239 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
18240 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
18241 * filelock.c (current_lock_owner): Likewise.
18242 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
18243 * sysdep.c: Include allocator.h, careadlinkat.h.
18244 (emacs_no_realloc_allocator): New static constant.
18245 (emacs_readlink): New function.
18246 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
18247 ../lib/careadlinkat.h.
18249 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
18251 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
18252 first non-nil return value).
18254 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
18256 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
18257 if not defined (Bug#8403).
18259 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
18261 * xdisp.c (display_count_lines): Remove parameter `start',
18262 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
18263 (get_char_face_and_encoding): Remove parameter `multibyte_p',
18264 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

18266 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
18267 and thereabouts. All callers changed.
18268 (get_per_char_metric): Remove parameter `f', unused since
18269 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
18271 2011-04-02 Jim Meyering <meyering@redhat.com>
18273 do not dereference NULL upon failed strdup
18274 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
18275 (ns_get_family): Likewise.
18277 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
18279 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
18281 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
18283 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
18286 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
18288 Add lexical binding.
18290 * window.c (Ftemp_output_buffer_show): New fun.
18291 (Fsave_window_excursion):
18292 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
18294 * lread.c (lisp_file_lexically_bound_p): New function.
18295 (Fload): Bind Qlexical_binding.
18296 (readevalloop): Remove `evalfun' arg.
18297 Bind Qinternal_interpreter_environment.
18298 (Feval_buffer): Bind Qlexical_binding.
18299 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
18301 (syms_of_lread): Declare `lexical-binding'.
18303 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
18305 * keyboard.c (eval_dyn): New fun.
18306 (menu_item_eval_property): Use it.
18308 * image.c (parse_image_spec): Use Ffunctionp.
18310 * fns.c (concat, mapcar1): Accept byte-code-functions.
18312 * eval.c (Fsetq): Handle lexical vars.
18313 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
18314 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
18315 (FletX, Flet): Obey lexical binding.
18316 (Fcommandp): Handle closures.
18317 (Feval): New `lexical' arg.
18318 (eval_sub): New function extracted from Feval. Use it almost
18319 everywhere where Feval was used. Look up vars in lexical env.
18321 (Ffunctionp): Move from subr.el.
18322 (Ffuncall): Handle closures.
18323 (apply_lambda): Remove `eval_flags'.
18324 (funcall_lambda): Handle closures and new byte-code-functions.
18325 (Fspecial_variable_p): New function.
18326 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
18327 but without exporting it to Lisp.
18329 * doc.c (Fdocumentation, store_function_docstring):
18330 * data.c (Finteractive_form): Handle closures.
18332 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
18335 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
18337 (exec_byte_code): New function extracted from Fbyte_code to handle new
18338 calling convention for byte-code-functions. Add new byte-codes.
18340 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
18342 * alloc.c (Fmake_symbol): Init new `declared_special' field.
18344 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
18346 * xdisp.c (redisplay_internal): Fix prototype.
18348 2011-03-31 Eli Zaretskii <eliz@gnu.org>
18350 * xdisp.c (SCROLL_LIMIT): New macro.
18351 (try_scrolling): Use it when setting scroll_limit.
18352 Limit scrolling to 100 screen lines.
18353 (redisplay_window): Even when falling back on "recentering",
18354 position point in the window according to scroll-conservatively,
18355 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
18357 (try_scrolling): When point is above the window, allow searching
18358 as far as scroll_max, or one screenful, to compute vertical
18359 distance from PT to the scroll margin position. This prevents
18360 try_scrolling from unnecessarily failing when
18361 scroll-conservatively is set to a value slightly larger than the
18362 window height. Clean up the case of PT below the margin at bottom
18363 of window: scroll_max can no longer be INT_MAX. When aggressive
18364 scrolling is in use, don't let point enter the opposite scroll
18365 margin as result of the scroll.
18366 (syms_of_xdisp) <scroll-conservatively>: Document the
18367 threshold of 100 lines for never-recentering scrolling.
18369 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
18371 * dispextern.h (move_it_by_lines):
18372 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
18373 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
18374 (message_log_check_duplicate): Remove parameters `prev_bol' and
18375 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
18376 (redisplay_internal): Remove parameter `preserve_echo_area',
18377 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
18379 * indent.c (Fvertical_motion):
18380 * window.c (window_scroll_pixel_based, Frecenter):
18381 Don't pass `need_y_p' to `move_it_by_lines'.
18383 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
18385 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
18386 steal a few bits to be more compact.
18387 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
18388 Remove unneeded casts.
18390 * bytecode.c (Fbyte_code): CAR and CDR can GC.
18392 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
18394 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
18395 binding" message (bug#7967).
18397 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
18399 Fix more problems found by GCC 4.6.0's static checks.
18401 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
18402 Remove unused local var.
18404 * editfns.c (Fmessage_box): Remove unused local var.
18406 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
18407 (note_mode_line_or_margin_highlight, note_mouse_highlight):
18408 Omit unused local vars.
18409 * window.c (shrink_windows): Omit unused local var.
18410 * menu.c (digest_single_submenu): Omit unused local var.
18411 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
18412 Omit unused local var.
18414 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
18415 Don't assume string length fits in int.
18416 (keyremap_step, read_key_sequence): Use size_t for sizes.
18417 (read_key_sequence): Don't check last_real_key_start redundantly.
18419 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
18420 instead of alloca (Bug#8344).
18422 * eval.c (Fbacktrace): Don't assume nargs fits in int.
18423 (Fbacktrace_frame): Don't assume nframes fits in int.
18425 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
18427 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
18430 * term.c (produce_glyphless_glyph): Remove unnecessary test.
18432 * cm.c (calccost): Turn while-do into do-while, for clarity.
18434 * keyboard.c (syms_of_keyboard): Use the same style as later
18435 in this function when indexing through an array. This also
18436 works around GCC bug 48267.
18438 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
18440 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
18442 * chartab.c (sub_char_table_ref_and_range): Redo for slight
18443 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
18445 * keyboard.c, keyboard.h (num_input_events): Now size_t.
18446 This avoids undefined behavior on integer overflow, and is a bit
18447 more convenient anyway since it is compared to a size_t variable.
18449 Variadic C functions now count arguments with size_t, not int.
18450 This avoids an unnecessary limitation on 64-bit machines, which
18451 caused (substring ...) to crash on large vectors (Bug#8344).
18452 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
18453 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

18458 * eval.c (struct backtrace.nargs, interactive_p)
18459 (internal_condition_case_n, run_hook_with_args, apply_lambda)
18460 (funcall_lambda, mark_backtrace): Likewise.
18461 * fns.c (concat): Likewise.
18462 * frame.c (x_set_frame_parameters): Likewise.
18463 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
18464 0 if not found, not -1. All callers changed.
18466 * alloc.c (garbage_collect): Don't assume stack size fits in int.
18467 (stack_copy_size): Now size_t, not int.
18468 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
18470 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
18472 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
18473 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
18474 All callers changed.
18476 * lisp.h (multibyte_char_to_unibyte):
18477 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
18478 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
18479 * character.h (CHAR_TO_BYTE8):
18480 * cmds.c (internal_self_insert):
18481 * editfns.c (general_insert_function):
18482 * keymap.c (push_key_description):
18483 * search.c (Freplace_match):
18484 * xdisp.c (message_dolog, set_message_1): All callers changed.
18486 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
18488 * keyboard.c (safe_run_hook_funcall): New function.
18489 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
18490 don't set the hook to nil, but remove the offending function instead.
18491 (Qcommand_hook_internal): Remove, unused.
18492 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
18493 Vcommand_hook_internal.
18495 * eval.c (enum run_hooks_condition): Remove.
18496 (funcall_nil, funcall_not): New functions.
18497 (run_hook_with_args): Call each function through a `funcall' argument.
18498 Remove `cond' argument, now redundant.
18499 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
18500 (Frun_hook_with_args_until_failure): Adjust accordingly.
18501 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
18503 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
18505 * dispextern.h (string_buffer_position): Remove declaration.
18507 * print.c (strout): Remove parameter `multibyte', unused since
18508 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
18510 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
18511 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
18512 All callers changed.
18514 * w32.c (_wsa_errlist): Use braces for struct initializers.
18516 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
18517 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
18518 All callers changed.
18519 (string_buffer_position): Likewise. Also, make static (it's never
18520 used outside xdisp.c).
18521 (cursor_row_p): Remove parameter `w', unused since
18522 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

18524 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
18525 All callers changed.
18527 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
18529 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

18535 (ns_update_auto_hide_menu_bar): New functions.
18536 (ns_update_begin): Call ns_update_auto_hide_menu_bar.

18540 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
18542 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
18544 * nsmenu.m (runDialogAt): Remove argument to timer_check.
18546 2011-03-27 Glenn Morris <rgm@gnu.org>
18548 * syssignal.h: Replace RETSIGTYPE with void.
18549 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
18550 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
18551 Replace SIGTYPE with void everywhere.
18552 * s/usg5-4-common.h (SIGTYPE): Remove definition.

18555 2011-03-26 Eli Zaretskii <eliz@gnu.org>
18557 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
18558 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
18560 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
18562 * w32.c (read_unc_volume): Use parameter `henum', instead of
18563 global variable `wget_enum_handle'.
18565 * keymap.c (describe_vector): Remove parameters `indices' and
18566 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.
18567 (describe_map, Fdescribe_vector): Adjust calls to `describe_vector'.
18569 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
18571 * keyboard.c (timer_check): Remove parameter `do_it_now',
18572 unused since 1996-04-12T06:01:29Z!rms@gnu.org.
18573 (show_help_echo): Remove parameter `ok_to_overwrite_keystroke_echo',
18574 unused since 2008-04-19T19:30:53Z!monnier@iro.umontreal.ca.
18576 * keyboard.c (read_char):
18577 * w32menu.c (w32_menu_display_help):
18578 * xmenu.c (show_help_event, menu_help_callback):
18579 Adjust calls to `show_help_echo'.
18581 * gtkutil.c (xg_maybe_add_timer):
18582 * keyboard.c (readable_events):
18583 * process.c (wait_reading_process_output):
18584 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
18586 * insdel.c (adjust_markers_gap_motion):
18587 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.
18588 (gap_left, gap_right): Don't call it.
18590 2011-03-25 Chong Yidong <cyd@stupidchicken.com>

18636 * w32term.c (x_set_glyph_string_clipping):
18637 Don't pass uninitialized region to CombineRgn.
18639 2011-03-23 Juanma Barranquero <lekktu@gmail.com>

18661 2011-03-23 Julien Danjou <julien@danjou.info>
18663 * term.c (Fsuspend_tty, Fresume_tty):
18664 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
18665 * window.c (temp_output_buffer_show):
18666 * insdel.c (signal_before_change):
18667 * frame.c (Fhandle_switch_frame):
18668 * fileio.c (Fdo_auto_save):
18669 * emacs.c (Fkill_emacs):
18670 * editfns.c (save_excursion_restore):
18671 * cmds.c (internal_self_insert):
18672 * callint.c (Fcall_interactively):
18673 * buffer.c (Fkill_all_local_variables):
18674 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
18676 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
18677 unconditionally since it does the check itself.
18679 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
18681 Fix more problems found by GCC 4.5.2's static checks.
18683 * coding.c (encode_coding_raw_text): Avoid unnecessary test
18684 the first time through the loop, since we know p0 < p1 then.
18685 This also avoids a gcc -Wstrict-overflow warning.
18687 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
18688 leading to a memory leak, possible in functions like
18689 load_charset_map_from_file that can allocate an unbounded number
18690 of objects (Bug#8318).
18692 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
18693 that could (at least in theory) be that large.
18695 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
18696 This is less likely to overflow, and avoids undefined behavior if
18697 overflow does occur. All callers changed. Use strtoul to scan
18698 for the unsigned long integer.
18699 (pint2hrstr): Simplify and tune code slightly.
18700 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
18702 * scroll.c (do_scrolling): Work around GCC bug 48228.
18703 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
18705 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
18706 This also avoids a warning with gcc -Wstrict-overflow.
18707 (validate_x_resource_name): Simplify count usage.
18708 This also avoids a warning with gcc -Wstrict-overflow.
18710 * fileio.c (Fcopy_file): Report error if fchown or fchmod
18713 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
18715 * process.c (Fmake_network_process): Use socklen_t, not int,
18716 where POSIX says socklen_t is required in portable programs.
18717 This fixes a porting bug on hosts like 64-bit HP-UX, where
18718 socklen_t is wider than int (Bug#8277).
18719 (Fmake_network_process, server_accept_connection):
18720 (wait_reading_process_output, read_process_output):
18723 * process.c: Rename or move locals to avoid shadowing.
18724 (list_processes_1, Fmake_network_process):
18725 (read_process_output_error_handler, exec_sentinel_error_handler):
18726 Rename or move locals.
18727 (Fmake_network_process): Define label "retry_connect" only if needed.

18797 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
18799 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
18800 This should get cleaned up, so that child_setup has the
18801 same signature on all platforms.
18803 * callproc.c (call_process_cleanup): Now static.

18975 to use the following functions instead of these macros.
18976 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
18977 EMACS_INT, since callers assume the returned value fits in int.

18980 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

18991 (RETALLOC_IF): Define only if needed.
18992 (WORDCHAR_P): Likewise. This one is never needed, but is used
18993 only in a comment talking about a compiler bug, so put inside
18994 the #if 0 of that comment.
18995 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):

19024 gcpro1, gcpro2, etc.
19025 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
19027 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
19028 argument, for consistency with GCPRO2_VAR, etc: it is now the
19029 prefix of the variable, not the variable itself. All uses
19031 * dired.c (directory_files_internal, file_name_completion):
19032 Rename locals to avoid shadowing.
19034 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
19035 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
19036 dired.c's scmp function, had undefined behavior.
19037 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
19038 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
19039 * buffer.h: ... to here, because these macros use current_buffer,
19040 and the new implementation with inline functions needs to have
19041 current_buffer in scope now, rather than later when the macros
19043 (downcase, upcase1): New static inline functions.
19044 (DOWNCASE, UPCASE1): Reimplement using these functions.
19045 This avoids undefined behavior in expressions like
19046 DOWNCASE (x) == DOWNCASE (y), which previously suffered
19047 from race conditions in accessing the global variables
19048 case_temp1 and case_temp2.
19049 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
19050 * lisp.h (case_temp1, case_temp2): Remove their decls.
19051 * character.h (ASCII_CHAR_P): Move from here ...

19079 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.

19086 * buffer.c (fix_overlays_before): Mark locals as initialized.
19087 (fix_start_end_in_overlays): Likewise. This function should be
19088 simplified by using pointers-to-pointers, but that's a different

19091 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
19092 (report_overlay_modification): Rename locals to avoid shadowing.

19101 * systty.h: ... to here, so that they can be checked.
