1 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
3 Remove EMACS_OUTQSIZE+sleep hack.
4 * dispnew.c (update_frame_1): Remove hack for terminals slower
5 than 2400 bps, which throttled Emacs by having it sleep. This
6 code hasn't worked since at least 2007, when the multi-tty stuff
7 was added, and anyway those old terminals are long dead.
8 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
9 without the dispnew.c change, as dispnew.c doesn't include systty.h.
11 Fix data-loss with --version (Bug#9574).
12 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
13 as we can't assume that emacs_strerror is initialized, and strerror
15 (main): Invoke atexit earlier, to catch earlier instances of
16 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
18 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
20 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
21 (keyDown): Remap keypad keys to X11 virtual key codes.
23 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
25 Fix data-loss with --batch (Bug#9574).
26 * emacs.c: Include <close-stream.h>.
27 (close_output_streams): New function.
28 (main): Pass it to atexit, so that Emacs closes stdout and stderr
29 and handles errors appropriately.
30 (Fkill_emacs): Don't worry about flushing, as close_output_stream
33 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
34 The symptom is a diagnostic "GLib-WARNING **: In call to
35 g_spawn_sync(), exit status of a child process was requested but
36 SIGCHLD action was set to SIG_IGN and ECHILD was received by
37 waitpid(), so exit status can't be returned." The diagnostic
38 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
39 The real bug is a race condition between Emacs and glib: Emacs
40 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
41 so that glib can't find it. Work around the bug by invoking
42 waitpid only on subprocesses that Emacs itself creates.
43 * process.c (create_process, record_child_status_change):
44 Don't use special value -1 in pid field, as the caller now must
45 know the pid rather than having the callee infer it. The
46 inference was sometimes incorrect anyway, due to another race.
47 (create_process): Set new 'alive' member if child is created.
48 (process_status_retrieved): New function.
49 (record_child_status_change): Use it.
50 Accept negative 1st argument, which means to wait for the
51 processes that Emacs already knows about. Move special-case code
52 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
53 processes that have already been waited for, by testing and
54 clearing new 'alive' member.
55 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
56 now does this internally.
57 (handle_child_signal): Let record_child_status_change do all
58 the work, since we do not want to reap all exited child processes,
59 only the child processes that Emacs itself created.
60 * process.h (Lisp_Process): New boolean member 'alive'.
62 Omit duplicate definitions no longer needed with gcc -g3.
63 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
64 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
65 Define only as macros. There's no longer any need to also define
66 these symbols as enums or as constants, since we now assume
67 gcc -g3 when debugging.
69 2012-11-03 Eli Zaretskii <eliz@gnu.org>
71 * lisp.mk: Adjust comments to the fact that term/internal is now
72 loaded from loadup.el.
74 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
75 (msdos_fatal_signal): New function.
76 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
79 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
80 for GCC versions before 4.
81 (emacs_raise): Define to call msdos_fatal_signal.
83 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
84 iterator when starting in the middle of a display or overlay
87 2012-11-03 Chong Yidong <cyd@gnu.org>
89 * process.c (wait_reading_process_output): Clean up the last
92 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
94 * process.c (wait_reading_process_output): Avoid a race condition
95 with SIGIO delivery (Bug#11536).
97 2012-11-03 Chong Yidong <cyd@gnu.org>
99 * buffer.c (cursor_type): Untabify docstring.
101 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
103 * frame.h (struct frame): Drop can_have_scroll_bars member
104 which is meaningless for a long time. Adjust comments.
105 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
106 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
108 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
110 * window.c (decode_next_window_args): Update window arg after
111 calling decode_live_window and so fix crash reported at
112 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
113 by Juanma Barranquero <lekktu@gmail.com>.
114 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
115 * font.c (Ffont_at): Likewise.
117 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>

121 (EmacsFrameResize): Check if all is up to date before changing frame
124 2012-11-02 Eli Zaretskii <eliz@gnu.org>
126 Implement backtrace output for fatal errors on MS-Windows.
127 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
128 (BACKTRACE_LIMIT_MAX): New macro.
129 (w32_backtrace): New function.
130 (emacs_abort): Use w32_backtrace when the user chooses not to
131 attach a debugger. Update the text of the abort dialog.
133 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
135 Window-related stuff cleanup here and there.
136 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
137 Use decode_any_window.
138 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
139 * xdisp.c (Fformat_mode_line): Likewise.
140 * font.c (Ffont_at): Use decode_live_window.
141 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
142 * window.c (decode_next_window_args): Likewise.
143 (decode_any_window): Remove static.
144 * window.h (decode_any_window): Add prototype.
145 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
146 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
149 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
151 Remove pad from struct input_event.
152 * termhooks.h (struct input_event): Remove padding field.
154 * keyboard.c (event_to_kboard): Simplify because frame_or_window
155 member is never cons for a long time. Adjust comment.
156 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
157 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
158 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
159 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
161 2012-11-01 Eli Zaretskii <eliz@gnu.org>
163 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
165 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
167 Fix crash when using Emacs as commit editor for git (Bug#12697).
168 * callproc.c (setpgrp): Remove macro, as we now use setpgid
169 and it is configured in conf_post.h.
170 (Fcall_process): Don't invoke both setsid and setpgid; the former
171 is enough, if it exists.
172 * callproc.c (Fcall_process, child_setup):
173 * process.c (create_process): Use setpgid.
174 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
176 * dispnew.c (init_display): Initialize the foreground group
177 if we are running a tty display.
178 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
179 * lisp.h (init_foreground_group): New decl.
180 * sysdep.c (inherited_pgroup): New static var.
181 (init_foreground_group, tcsetpgrp_without_stopping)
182 (narrow_foreground_group, widen_foreground_group): New functions.
183 (init_sys_modes): Narrow foreground group.
184 (reset_sys_modes): Widen foreground group.
186 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
188 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
190 2012-10-31 Martin Rudalics <rudalics@gmx.at>
192 * minibuf.c (read_minibuf): Restore current buffer since
193 choose_minibuf_frame calling Fset_frame_selected_window may
194 change it (Bug#12766).
196 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
198 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
200 2012-10-30 Kenichi Handa <handa@gnu.org>
202 * font.c (Ffont_at): If WINDOW is specified and it is not
203 displaying the current buffer, signal an error.
205 2012-10-29 Daniel Colascione <dancol@dancol.org>
207 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode): In
208 preparation for fixing bug#12739, move these functions from
211 * coding.h, coding.c: ... to here, and compile them only when
212 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
213 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
215 2012-10-28 Eli Zaretskii <eliz@gnu.org>
217 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
218 (timer_loop, getitimer, setitimer): Use it instead of
219 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
221 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
224 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
226 * nsterm.m (NO_APPDEFINED_DATA): New define.
227 (last_appdefined_event_data): New variable
228 (last_appdefined_event): Remove.
229 (ns_select): Initialize t from last_appdefined_event_data instead
230 of [last_appdefined_event data1].
231 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
232 remove last_appdefined_event (Bug#12698).
234 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
236 * frame.c (x_set_font): Catch internal error.
238 2012-10-27 Eli Zaretskii <eliz@gnu.org>
240 Avoid overflow in w32 implementation of interval timers.
241 When possible, for ITIMER_PROF count only times the main thread
243 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
244 'volatile ULONGLONG' types. All the other data which was
245 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
246 (GetThreadTimes_Proc): New typedef.
247 (w32_get_timer_time): New function, returns a suitable time value
249 (timer_loop): Enter critical section when accessing ULONGLONG
250 values of the itimer_data struct, as these accesses are no longer
251 atomic. Call 'w32_get_timer_time' instead of 'clock'.
252 Remove unused variable.
253 (init_timers): Initialize s_pfn_Get_Thread_Times.
254 (start_timer_thread): Don't assign itimer->caller_thread here.
255 (getitimer): Assign itimer->caller_thread here.
256 (setitimer): Always call getitimer to get the value of ticks_now.
257 (sys_spawnve): Avoid compiler warning about format mismatch.
259 2012-10-26 Eli Zaretskii <eliz@gnu.org>
261 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
262 mouse movement events if the menu bar is active. This avoids
263 producing a busy "hour-glass" cursor by Windows if the mouse
264 pointer is positioned over a tooltip shown for some menu item.
266 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
268 Don't assume process IDs fit in int.
269 * emacs.c (shut_down_emacs) [!DOS_NT]:
270 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
271 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
272 Use pid_t, not int, to store process IDs, as 'int'
273 is not wide enough on a few platforms (e.g., AIX and IRIX).
275 2012-10-23 Kenichi Handa <handa@gnu.org>
277 The following change is to make face-font-rescale-alist work
278 correctly for non-ASCII fonts.
280 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
281 (font_open_for_lface): Handle Vface_font_rescale_alist.
283 2012-10-23 Chong Yidong <cyd@gnu.org>
285 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
287 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
289 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
291 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
293 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
296 2012-10-21 Glenn Morris <rgm@gnu.org>
298 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
300 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
303 * frame.c (Fmouse_position, Fmouse_pixel_position):
304 * xdisp.c (produce_stretch_glyph):
305 Declare local vars only when they're needed.
306 This is clearer and avoids a warning on OpenBSD about unused vars.
307 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
308 This is safer, and avoids OpenBSD warnings about unused vars.
309 * keyboard.c (record_menu_key): Remove unnecessary decl.
310 (poll_timer): Define only if POLL_FOR_INPUT is defined.
311 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
312 as our definition clashes with OpenBSD's.
313 * xfaces.c (load_face_colors, check_lface_attrs)
314 (get_lface_attributes_no_remap, get_lface_attributes)
315 (lface_fully_specified_p, x_supports_face_attributes_p)
316 (tty_supports_face_attributes_p, face_fontset, realize_face)
317 (realize_x_face, realize_tty_face):
318 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
319 merely Lisp_Object *. This is more informative and avoids
320 a warning on OpenBSD about accessing beyond an object's size.
322 2012-10-20 Chong Yidong <cyd@gnu.org>
324 * lread.c (Fload): Doc fix (Bug#12592).
326 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
328 * font.c (Ffont_at): Fix previous change.
330 2012-10-19 Eli Zaretskii <eliz@gnu.org>
332 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
333 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
336 * alloc.c (NSTATICS): Decrease to 0x800.
338 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>

343 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
345 * nsterm.m (ns_select): Check writefds before call to
346 FD_ISSET (Bug#12668).
348 2012-10-18 Daniel Colascione <dancol@dancol.org>
350 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
351 (staticpro): If we run out of staticpro slots, die with an
352 informative error instead of just calling emacs_abort.
354 2012-10-18 Martin Rudalics <rudalics@gmx.at>
356 Fix two flaws reported by Dmitry Antipov.

398 (Fcygwin_convert_path_from_windows): Use EQ to compare 2
399 Lisp_Object values. (Bug#12661)
401 * w32fns.c (w32_msg_pump): Use XIL instead of casting an integer
402 to Lisp_Object. (Bug#12661)
404 2012-10-17 Kenichi Handa <handa@gnu.org>
406 * xdisp.c (reseat_1): Make the information stored in it->cmp_it

441 can be used (Bug#12600).
442 (resize_frame_windows, grow_mini_window, shrink_mini_window):
443 Set windows_or_buffers_changed.
445 2012-10-15 Daniel Colascione <dancol@dancol.org>
447 * dbusbind.c: Fix cygw32 build break when compiling with dbus
448 enabled by undefining the symbol "interface", which the platform
449 headers define to something incompatible.
451 2012-10-14 Daniel Colascione <dancol@dancol.org>
453 * image.c (init_tiff_functions, init_imagemagick_functions)
454 (init_svg_functions): Fix cygw32 build break by using these

478 removed or renamed by some other process immediately after Emacs
479 writes it but before Emacs stats it. Do not assume that stat (or
481 * image.c (slurp_file): Resolve the file name with fopen + fstat
482 rather than stat + fopen.
483 (pbm_read_file) [0]: Remove unused code with stat race.
484 * process.c (allocate_pty) [HAVE_PTYS && !PTY_ITERATION && !PTY_OPEN]:
485 Remove ineffective code with stat race.
487 2012-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
489 * doc.c (get_doc_string): Don't signal an error if the file is missing.
491 2012-10-12 Jan Djärv <jan.h.d@swipnet.se>
493 * nsterm.m (hold_event_q): New static variable.

510 * fileio.c (check_existing): New function.
511 (make_temp_name, Ffile_exists_p, Ffile_writable_p): Call it
512 instead of calling 'stat', when what's needed is to check whether
513 a file exists. This avoids expensive system calls on MS-Windows.
516 * w32.c (init_environment): Call 'check_existing' instead of 'stat'.
518 * lread.c (openp) [WINDOWSNT]: Call 'access' instead of 'stat' to
519 determine whether a file exists and is not a directory.
521 * lisp.h (check_existing): Add prototype.
523 2012-10-12 Jan Djärv <jan.h.d@swipnet.se>

555 Use bool for booleans.
556 * lread.c (safe_to_load_version): Rename from safe_to_load_p,
557 as it's not a predicate. All uses changed. Omit unnecessary
560 2012-10-11 Dmitry Antipov <dmantipov@yandex.ru>
562 * editfns.c (save_excursion_save): Use nil if mark points to nowhere.

606 Use bool for boolean.
607 * keyboard.c (timers_run, swallow_events)
608 (detect_input_pending_run_timers):
609 * process.c (wait_reading_process_output):
610 Use unsigned for counter where wraparound-on-overflow is desired,
611 since unsigned is guaranteed to have that behavior and signed is not.
612 (read_char): Use ptrdiff_t for string length.
613 (get_input_pending): Remove first argument, since it was always
614 the same pointer-to-int (now pointer-to-boolean) &input_pending,
615 and behave as if it had that value. Return new value of
616 input_pending. All callers changed.
617 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
618 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
620 * keymap.c (push_key_description): Omit last arg, which was always 1.
623 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.
625 2012-10-10 Juanma Barranquero <lekktu@gmail.com>

634 initializer for PVEC_NORMAL_VECTOR.
636 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
638 Clean out old termopts cruft.
639 * termopts.h (flow_control, meta_key): Remove unused decls.
640 * dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c:
641 Don't include termopts.h.
643 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
645 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
647 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
649 * commands.h (immediate_quit): Remove duplicate decl.
651 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>

656 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
658 2012-10-09 Eli Zaretskii <eliz@gnu.org>
660 * w32fns.c (w32_last_error): Change the return value to DWORD, to
661 match what GetLastError returns. Explain why the function is
664 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
665 'is_tooltip_frame', to avoid confusion with its global namesake.
667 2012-10-08 Daniel Colascione <dancol@dancol.org>
669 * xdisp.c (start_hourglass): Call w32_note_current_window when
670 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
671 build that caused Emacs to display the hourglass cursor forever.
673 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
674 which is broken under remote desktop, calculate the number of
675 colors available for a display based on the display's number of
676 planes and number of bits per pixel per plane. (bug#10397).
678 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
680 * nsfont.m (Vfonts_in_cache): New variable.
681 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
682 are used. Add cached fonts to Vfonts_in_cache.
683 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
685 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
687 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
689 (FONT_H): Define after FRAME_H.
690 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
693 * w32term.c: Remove leftover declaration of keyboard_codepage.
695 2012-10-08 Eli Zaretskii <eliz@gnu.org>
697 * makefile.w32-in (FONT_H): Add $(FRAME_H).
698 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
699 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
700 (GLOBAL_SOURCES): Add cygw32.c.
701 ($(BLD)/unexw32.$(O)):
703 ($(BLD)/w32console.$(O)):

709 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
711 (x_to_w32_color): Don't modify the argument, modify a copy instead.
713 2012-10-08 Daniel Colascione <dancol@dancol.org>
715 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
716 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
717 accidental message numbering hole. Change other messages to
720 * w32select.h (HAVE_W32SELECT): Remove.
722 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
723 w32common.h instead of w32heap.h.
725 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)

733 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
734 (w32_minor_version, w32_build_number, w32_subtype):
735 Remove duplicate definitions.
737 * w32fns.c: Include w32common.h; include w32heap.h only in
740 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
741 Use `report_file_error' instead of `error' in order to better
742 inform users of what went wrong. Increase NTGUI_UNICODE file
743 dialog box file name length to 32k, the maximum allowed by the NT
746 * w32common.h: New file.
747 (ROUND_UP, ROUND_DOWN, get_page_size)
748 (get_allocation_unit, get_processor_type, get_w32_major_version)
749 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
750 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
751 (OS_NT, os_subtype, cache_system_info): Move here.
753 * unexw32.c, unexcw.c: Include w32common.h.
755 * emacs.c (main): Use (defined (WINDOWSNT) || defined
756 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
757 to call syms_of_w32select.
759 * cygw32.h: Remove obsolete EXFUN declarations.
761 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
763 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
764 of w32inevt.o from SOME_MACHINE_OBJECTS.
766 2012-10-08 Daniel Colascione <dancol@dancol.org>
768 * image.c: Permanent fix for JPEG compilation issue --- limit
769 jpeglib `boolean' redefinition to Cygwin builds.
771 2012-10-08 Eli Zaretskii <eliz@gnu.org>
773 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
775 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
778 2012-10-08 Daniel Colascione <dancol@dancol.org>
780 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
781 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
782 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
783 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
784 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
785 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
786 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
787 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
788 now a supported configuration.
790 * Makefile.in: consolidate image variables into LIBIMAGE; add
791 W32_OBJ and W32_LIBS. Compile new files.
794 (_DebPrint) declare tracing facility for W32 debugging. We need
795 to unify tracing later.
797 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
798 unconditional use of W32 Unicode functions. Cygwin runs only on
799 100% Unicode operating systems.
801 * cygw32.c: New file. Define Cygwin-specific facilities.
802 (Fcygwin_convert_path_to_windows)
803 (Fcygwin_convert_path_from_windows): New user functions for
804 accessing Cygwin path-munging routines.
806 * cygw32.h: New file.
807 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
808 UTF-16LE strings temporarily inside non-Lisp-visible string
811 (w32_strerror): Just what it says on the tin.
813 * emacs.c: Make the NS fork-then-exec code for daemon-launching
814 also run for Cygwin; both systems have the same problem with using
815 GUI facilities in a forked child. Also call syms_of_cygw32,
816 syms_of_w32select in correct places.
818 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
819 needs fork-then-exec for daemon launching.
821 * font.h: Include frame.h.
823 * image.c: Use the image library cache machinery only when we're
824 compiling for native WINDOWSNT; Cygwin can use shared libraries
825 like any other Unixlike system.
827 * keyboard.c: Clarify a comment regarding the input loop.
829 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
830 functions directly instead of trying to detect at runtime that our
831 host operating system supports them. We make this change for two
832 reasons: Cygwin lacks support for the multibyte character
833 conversion functions used by the legacy menu code, and Cygwin
834 never needs to rely on non-Unicode APIs.
836 * unexw32.c (hinst): Declare extern.
838 * w32.c: Change header order;
839 (w32_strerror): Move to w32fns.c because we need it for
840 non-WINDOWSNT builds.
842 * w32.h: Add #error macro to make sure we don't include w32.h for
843 Cygwin builds. Remove w32select declarations.
845 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
846 w32fns.c. w32console.c is WINDOWSNT-only.
848 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
849 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
851 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
852 (w32_major_version, w32_minor_version, w32_build_number)
853 (os_subtype, sound_type): Define here
854 (w32_defined_color): Make color parameter const for consistency
855 with other _defined_color functions.
856 (w32_createwindow): Unconditionally call w32_init_class instead of
857 doing so only when hprevinst is non-NULL. Plumbing hprevinst
858 through the code is complex and unnecessary because class
859 registration is practically free.
860 (w32_name_of_message): New EMACSDEBUG-only function.
861 (Fset_message_beep): Move here
862 (Fx_open_connection): Require that the display name for Windows be
863 "w32" for consistency, emacsclient disambiguation, and maybe, one
864 day, multi-window-system support.
865 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
866 Cygwin files for W32 GUI facilities, since these clearly don't
869 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
870 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
871 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
872 (w32_last_error): Remove.
874 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
876 * w32heap.c (syspage_mask): Declare here.
877 (cache_system_info): Remove.
879 * w32inevt.c (faked_key): Define globally, not statically.
880 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
881 (w32_console_toggle_lock_key): Move to w32fns.c.
883 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
885 * w32proc.c (_DebPrint): Move to w32fns.c.
886 * w32select.c: Include string.h, stdio.h for Cygwin.
887 * w32select.h: New File.
889 * w32term.c: Include io.h for non-CYGWIN builds; needed for
891 (w32_message_fd): New variable. Under Cygwin, holds the file
892 descriptor the system used to tell us about pending thread
895 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
896 that prevented compilation under non-WINDOWSNT systems.
898 (w32_initialize): Open /dev/windows and assign it to
899 w32_message_fd. Provide w32 feature.
901 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
902 (WM_EMACS_INPUT_READY): add.
903 (prepend_msg, w32_message_fd): Declare globally.
906 (keyboard_handle): Use only when WINDOWSNT.
907 (notify_msg_ready): New function. Posts a message to the main
908 thread's message queue under CYGWIN, which wakes up the main
909 thread from select(2) by making the /dev/windows file descriptor
910 ready. Under WINDOWSNT, it sets an event the same way the old
913 (post, prepend_msg): Actually call notify_msg_ready instead of
914 setting the input event directly.
916 2012-10-07 Eli Zaretskii <eliz@gnu.org>
918 * ralloc.c (relinquish): If a heap is ready to be relinquished,
919 but it still has blocs in it, don't return it to the system,
920 instead of aborting. (Bug#12402)
922 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
924 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
926 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
927 MAC_OS_X_VERSION_10_6.

937 * nsmenu.m (fillWithWidgetValue:): Remove code for <
938 MAC_OS_X_VERSION_10_2.
940 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
942 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
943 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
945 * nsterm.m (ns_in_resize): Remove (Bug#12479).
946 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
947 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
948 Remove ns_in_resize check.
949 (ns_clear_frame_area): Remove resize handle code.
951 * nsfns.m (ns_in_resize): Remove.
952 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
953 Remove ns_in_resize check.
955 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
957 Improve sys_siglist detection.
958 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
959 defined as a macro, as is done in Solaris.
960 (sys_siglist_entries): New macro.
961 (save_strsignal): Use it.
962 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
963 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
965 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
967 * nsfns.m (Fx_create_frame): Call x_default_parameter with
968 fullscreen/Fullscreen.

973 * nsterm.m (x_make_frame_visible): Check for fullscreen.
974 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
975 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
976 (windowDidResize:): Check for correct window if old style fullscreen.
977 Capitalize word in comment. Remove incorrect comment.
978 (initFrameFromEmacs:): tbar_height renamed tibar_height.
979 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
980 error in drawing background.
981 (toggleFullScreen:): Remove comment. Rearrange calls.
982 Set toolbar values to zero, save old height in tobar_height.
983 Restore tool bar height when leaving fullscreen.
984 (canBecomeMainWindow): New function.
986 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>

990 2012-10-05 Eli Zaretskii <eliz@gnu.org>
992 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
994 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
995 that time stamps of directories could also be changed.
996 Don't request the too broad GENERIC_WRITE, only the more restrictive
997 FILE_WRITE_ATTRIBUTES access rights.
999 * fileio.c (Fset_file_times): Special-case ignoring errors for
1000 directories only on MSDOS, not on MS-Windows.
1002 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
1004 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
1006 2012-10-04 Eli Zaretskii <eliz@gnu.org>
1008 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
1009 see whether CreateFile failed.
1011 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
1013 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
1014 to avoid similar races.
1015 * keyboard.c (pending_signals): Now bool, not int.
1017 Port timers to OpenBSD, plus check for timer failures.
1018 OpenBSD problem reported by Han Boetes.
1019 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
1021 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
1022 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
1023 like OpenBSD, which has timer_settime but does not declare it.
1024 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
1025 whether to use itimerspec-related primitives. All uses of
1026 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
1028 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
1030 * profiler.c (handle_profiler_signal): Fix a malloc race
1031 that caused Emacs to hang on Fedora 17 when profiling Lisp.
1033 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
1035 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
1037 2012-10-02 Eli Zaretskii <eliz@gnu.org>
1039 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
1040 consistent with the change in return value of 'safe_strsignal'.
1042 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
1044 Prefer plain 'static' to 'static inline' (Bug#12541).
1045 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
1046 (bidi_set_sor_type, bidi_push_embedding_level)
1047 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

1052 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
1053 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
1054 Now 'static', not 'static inline'.
1056 Count overruns when profiling; change units to ns.
1057 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
1058 Give extra weight to samples after overruns, to attempt to count
1059 the time more accurately.
1060 (setup_cpu_timer): Change sampling interval units from ms to ns, since
1061 the underlying primitives nominally do ns.
1062 (Fprofiler_cpu_start): Document the change. Mention that
1063 the sampling intervals are only approximate.
1065 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
1067 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
1069 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
1070 case for the special 0 coding-system.
1072 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
1073 (Fmake_overlay): Remove redundant tests.
1074 (fix_start_end_in_overlays): Remove redundant recentering.
1076 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
1078 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
1079 Update dependencies.
1081 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
1083 Fix a malloc race condition involving strsignal.
1084 A signal can arrive in the middle of a malloc, and Emacs's signal
1085 handler can invoke strsignal, which can invoke malloc, which is
1086 not portable. This race condition bug makes Emacs hang on GNU/Linux.
1087 Fix it by altering the signal handler so that it does not invoke
1089 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
1090 * process.c (status_message): Use const pointer, in case strsignal
1091 is #defined to safe_strsignal.
1092 * sysdep.c (sys_siglist, init_signals): Always define and
1093 initialize a substitute sys_siglist if the system does not define
1094 one, even if HAVE_STRSIGNAL.
1095 (safe_strsignal): Rename from strsignal. Always define,
1096 using sys_siglist. Return a const pointer.
1097 * syssignal.h (safe_strsignal): New decl.
1098 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
1100 2012-10-01 Eli Zaretskii <eliz@gnu.org>
1102 * w32proc.c (timer_loop): Fix code that waits for timer
1103 expiration, to avoid high CPU usage.
1105 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
1107 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
1108 (sweep_weak_table): Remove redundant prototypes.
1110 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
1112 * emacs.c: Move the inclusion of TERM_HEADER after including
1113 windows.h on WINDOWSNT. This avoids compilation problems with
1116 2012-10-01 Eli Zaretskii <eliz@gnu.org>
1118 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
1119 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
1120 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
1121 as the previous version used 'void *'.
1123 * ralloc.c (ROUNDUP): Fix last change.
1124 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
1127 * w32proc.c <disable_itimers>: New static flag.
1128 (init_timers): Initialize it to zero, after creating the critical
1129 sections used by the timer threads.
1130 (term_timers): Set to 1 before deleting the critical sections.
1131 (getitimer, setitimer): If disable_itimers is non-zero, return an
1132 error indication without doing anything. Reported by Fabrice
1133 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
1134 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
1136 [!HAVE_SETITIMER]: Behave as the previous version that didn't
1139 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
1140 term_ntproc after all the other bookkeeping, to get timers working
1141 as long as possible.
1143 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
1145 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
1146 Suggested by Juri Linkov in
1147 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
1149 Prefer plain 'static' to 'static inline' (Bug#12541).
1150 With static functions, modern compilers inline pretty well by
1151 themselves; advice from programmers often hurts as much as it helps.
1152 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
1153 this change shrinks the text size of the Emacs executable by 1.1%
1154 without affecting CPU significantly in my benchmark.
1155 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

1235 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
1237 Revert the FOLLOW-SYMLINKS change for file-attributes.
1238 Doing it right would require several changes to Tramp, and there's
1239 not enough time to get that tested before the freeze today.
1240 * dired.c (directory_files_internal, Ffile_attributes):
1243 * frame.c (x_report_frame_params): Port better to wider ints.
1244 Do not assume that EMACS_UINT is the same width as uprintmax_t,

1443 (profiler_timer, profiler_timer_ok) [HAVE_TIMER_SETTIME]:
1445 (enum profiler_cpu_running): New enum.
1446 (profiler_cpu_running): Now of that enum type, not bool.
1447 All uses changed to store the new value.
1448 (handle_profiler_signal): Rename from sigprof_handler_1,
1449 for consistency with other handlers. Do not check whether
1450 cpu_log is a hash-table if garbage collecting, since it
1451 doesn't matter in that case.
1452 (deliver_profiler_signal): Rename from sigprof_handler,
1453 for consistency with other handlers.
1454 (setup_cpu_timer): New function, with much of what used to be in
1455 Fprofiler_cpu_start. Check for out-of-range argument.
1456 Prefer timer_settime if available, and prefer
1457 thread cputime clocks, then process cputime clocks, then
1458 monotonic clocks, to the old realtime clock. Use make_timeval
1459 to round more-correctly when falling back to setitimer.
1460 (Fprofiler_cpu_start): Use it.
1461 (Fprofiler_cpu_stop): Prefer timer_settime if available.
1462 Don't assume that passing NULL as the 2nd argument of setitimer
1463 is the same as passing a pointer to all-zero storage.
1464 Ignore SIGPROF afterwards.
1465 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
1466 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
1467 non-fatal signal handlers. Ignore SIGPROF on startup.
1468 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
1469 in profiler.c, since sysdep.c now uses it.
1471 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
1472 Suggested by Eli Zaretskii in
1473 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

1486 (Fbacktrace_frame): Adjust accordingly.
1488 2012-09-28 Glenn Morris <rgm@gnu.org>
1490 * eval.c (Frun_hook_with_args, Frun_hook_with_args_until_success)
1491 (Frun_hook_with_args_until_failure): Doc fixes.
1493 2012-09-28 Eli Zaretskii <eliz@gnu.org>
1495 * xdisp.c (syms_of_xdisp) <Qredisplay_internal>: Rename from

1523 2012-09-26 Paul Eggert <eggert@cs.ucla.edu>
1525 * character.h (MAYBE_UNIFY_CHAR): Remove.
1526 * charset.c, charset.h (maybe_unify_char): Now static.
1527 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
1528 Since this stuff is now private to charset.c, there's no need for
1529 a public macro and no need to inline by hand.

1558 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
1560 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
1562 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
1564 Prefer POSIX timers if available.
1565 They avoid a race if the timer is too close to the current time.
1566 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
1567 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
1568 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
1570 2012-09-25 Eli Zaretskii <eliz@gnu.org>

1573 CHAR_STRING_ADVANCE.
1574 (STRING_CHAR_ADVANCE_NO_UNIFY): Make it an alias of
1575 STRING_CHAR_ADVANCE.

1584 * image.c (reset_image_types): New function.
1586 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.

1591 (globals_of_w32) <Vlibrary_cache>: Do not initialize.
1593 * w32.h (Vlibrary_cache): Do not declare.
1595 2012-09-25 Eli Zaretskii <eliz@gnu.org>
1597 * w32proc.c (sys_signal): Handle all signals defined by the
1598 MS-Windows runtime, not just SIGCHLD. Actually install the signal
1599 handlers for signals supported by Windows. Don't override
1600 term_ntproc as the handler for SIGABRT.
1601 (sigaction): Rewrite to call sys_signal instead of duplicating its
1603 (sys_kill): Improve commentary.
1605 * w32.c (term_ntproc): Accept (and ignore) one argument, for
1606 consistency with a signature of a signal handler. All callers
1608 (init_ntproc): Accept an argument DUMPING. If dumping, don't
1609 install term_ntproc as a signal handler for SIGABRT, as that
1610 should be done by the dumped Emacs.
1612 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
1614 * w32select.c (term_w32select): Protect against repeated
1615 invocation by setting clipboard_owner to NULL after calling
1618 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
1619 and term_ntproc to their modified signatures.
1621 * character.c (char_string, string_char): Remove calls to
1622 MAYBE_UNIFY_CHAR. See the discussion starting at
1623 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
1626 2012-09-25 Chong Yidong <cyd@gnu.org>
1628 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
1630 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
1632 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
1633 when encountering an unknown bytecode.
1635 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
1637 image.c, indent.c: Use bool for booleans.
1638 * dispextern.h (struct image_type): Members valid_p, load, init
1639 now return bool, not int. All uses changed.
1640 * image.c: Omit unnecessary static decls.
1641 (x_create_bitmap_mask, x_build_heuristic_mask):
1642 Return void, not int, since callers don't care about the return value.

1673 2012-09-24 Chong Yidong <cyd@gnu.org>
1675 * chartab.c (Fset_char_table_default): Obsolete function removed.
1677 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
1679 Move pid_t related decls out of lisp.h.
1680 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
1681 (interruptible_wait_for_termination):
1682 Move these decls from lisp.h to syswait.h, since they use pid_t.
1683 Needed on FreeBSD; see Herbert J. Skuhra in
1684 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
1685 * callproc.c: Include syswait.h.

1703 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):

1705 Use bool for boolean.
1706 * gtkutil.c (xg_update_frame_menubar):

1731 2012-09-23 Eli Zaretskii <eliz@gnu.org>
1733 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
1734 fatal_error_backtrace.
1736 * w32proc.c (sys_kill): Undo last change: don't do anything when
1737 invoked to deliver SIGABRT to our own process. This is now
1738 handled by emacs_raise.
1740 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
1742 * w32term.c (w32_read_socket): Remove leftover reference to
1743 interrupt_input_pending.
1745 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
1747 Do not use SA_NODEFER.
1748 Problem reported by Dani Moncayo in
1749 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
1751 * sysdep.c (emacs_abort): Do not reset signal handler.
1752 * emacs.c (terminate_due_to_signal): Reset signal handler here.
1753 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
1754 wanted even on POSIXish hosts, and it doesn't work on Windows.
1756 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
1758 * xterm.c (x_term_init): Call fixup_locale before and after calling
1759 gtk_init (Bug#12392).
1761 2012-09-23 Chong Yidong <cyd@gnu.org>
1763 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
1764 Vdynamic_library_alist.
1766 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
1767 (Fgnutls_available_p): Caller changed.
1769 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
1770 (Flibxml_parse_xml_region): Likewise.
1772 * dispextern.h (struct image_type): Remove arg from init function.
1774 * image.c (Finit_image_library, lookup_image_type)
1775 (define_image_type): Remove now-unneeded second arg.
1776 (init_xpm_functions, init_png_functions, init_jpeg_functions)
1777 (init_tiff_functions, init_gif_functions, init_svg_functions):
1778 Arglist and w32_delayed_load calling convention changed.
1779 (gs_type): Remove init_gs_functions; there is no such function.
1780 (valid_image_p, make_image): Fix caller to lookup_image_type.
1782 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
1784 Simplify and avoid signal-handling races (Bug#12471).
1786 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
1787 Avoid recursive loop if there's a fatal error in the function itself.
1788 * atimer.c (pending_atimers):
1789 * blockinput.h: Don't include "atimer.h"; no longer needed.
1790 (interrupt_input_pending): Remove. All uses removed.
1791 pending_signals now counts both atimers and ordinary interrupts.
1792 This is less racy than having three separate pending-signal flags.
1793 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
1795 Rename from their upper-case counterparts BLOCK_INPUT,
1796 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
1797 INPUT_BLOCKED_P, and turn into functions. All uses changed.
1798 This makes it easier to access volatile variables more accurately.
1799 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
1800 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
1801 that's more reliable if the code is buggy and sets
1802 interrupt_input_blocked to a negative value. All uses changed.
1803 * atimer.c (deliver_alarm_signal):
1804 Remove. No need to deliver this to the parent; any thread can
1805 handle this signal now. All uses replaced by underlying handler.
1806 * atimer.c (turn_on_atimers):
1807 * dispnew.c (handle_window_change_signal):
1808 * emacs.c (handle_danger_signal):
1809 * keyboard.c (kbd_buffer_get_event):
1810 Don't reestablish signal handler; not needed with sigaction.
1811 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
1813 Rework to avoid unnecessary accesses to volatile variables.
1814 (UNBLOCK_INPUT_TO): Now a function.
1815 (totally_unblock_input, unblock_input): New decls.
1816 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
1817 (init_data): Remove. Necessary stuff now done in init_signal.
1818 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
1819 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
1820 (fatal_error_code): Remove; no longer needed.
1821 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
1822 it doesn't always backtrace. All uses changed. No need to reset
1823 signal to default, since sigaction and/or die does that for us now.
1824 Use emacs_raise (FOO), not kill (getpid (), FOO).
1825 (main): Check more-accurately whether we're dumping.
1826 Move fatal-error setup to sysdep.c
1827 * floatfns.c: Do not include "syssignal.h"; no longer needed.
1828 * gtkutil.c (xg_get_file_name, xg_get_font):
1829 Remove no-longer-needed signal-mask manipulation.
1830 * keyboard.c, process.c (POLL_FOR_INPUT):
1831 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
1832 * keyboard.c (read_avail_input): Remove.
1833 All uses replaced by gobble_input.
1834 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
1835 (kbd_buffer_store_event_hold, gobble_input):
1836 (record_asynch_buffer_change) [USABLE_SIGIO]:
1837 (store_user_signal_events):
1838 No need to mess with signal mask.
1839 (gobble_input): If blocking input and there are terminals, simply
1840 set pending_signals to 1 and return. All hooks changed to not
1841 worry about whether input is blocked.
1842 (process_pending_signals): Clear pending_signals before processing
1843 them, in case a signal comes in while we're processing.
1844 By convention callers now test pending_signals before calling us.
1845 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
1846 New functions, to support changes to blockinput.h.
1847 (handle_input_available_signal): Now extern.
1848 (reinvoke_input_signal): Remove. All uses replaced by
1850 (quit_count): Now volatile, since a signal handler uses it.
1851 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
1852 All callers changed. Block SIGINT only if not already blocked.
1853 Clear sigmask reliably, even if Fsignal returns, which it can.
1854 Omit unnecessary accesses to volatile var.
1855 (quit_throw_to_read_char): No need to restore sigmask.
1856 * keyboard.c (gobble_input, handle_user_signal):
1857 * process.c (wait_reading_process_output):
1858 Call signal-handling code rather than killing ourselves.
1859 * lisp.h: Include <float.h>, for...
1860 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
1861 (pending_signals): Now volatile.
1862 (syms_of_data): Now const if IEEE floating point.
1863 (handle_input_available_signal) [USABLE_SIGIO]:
1864 (terminate_due_to_signal, record_child_status_change): New decls.
1865 * process.c (create_process): Avoid disaster if memory is exhausted
1866 while we're processing a vfork, by tightening the critical section
1868 (send_process_frame, process_sent_to, handle_pipe_signal)
1869 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
1871 (send_process): No need for setjmp/longjmp any more, since the
1872 SIGPIPE stuff is now gone. Instead, report an error if errno
1874 (record_child_status_change): Now extern. PID and W are now args.
1875 Return void, not bool. All callers changed.
1876 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
1877 Remove. All uses removed. This bug should be fixed now in a
1879 (wait_for_termination_1): Use waitpid rather than sigsuspend,
1880 and record the child status change directly. This avoids the
1881 need to futz with the signal mask.
1882 (process_fatal_action): Move here from emacs.c.
1883 (emacs_sigaction_flags): New function, containing
1884 much of what used to be in emacs_sigaction_init.
1885 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
1886 caught by emacs, to make races less likely.
1887 (deliver_process_signal): Rename from handle_on_main_thread.
1889 (BACKTRACE_LIMIT_MAX): Now at top level.
1890 (thread_backtrace_buffer, threadback_backtrace_pointers):
1892 (deliver_thread_signal, deliver_fatal_thread_signal):
1893 New functions, for more-accurate delivery of thread-specific signals.
1894 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
1895 (deliver_arith_signal): Handle in this thread, not
1896 in the main thread, since it's triggered by this thread.
1897 (maybe_fatal_sig): New function.
1898 (init_signals): New arg DUMPING so that we can be more accurate
1899 about whether we're dumping. Caller changed.
1900 Treat thread-specific signals differently from process-general signals.
1901 Block all signals while handling fatal error; that's safer.
1902 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
1904 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
1905 Ignore SIGPIPE unless batch.
1906 (emacs_backtrace): Output backtrace for the appropriate thread,
1907 which is not necessarily the main thread.
1908 * syssignal.h: Include <stdbool.h>.
1909 (emacs_raise): New macro.
1910 * xterm.c (x_connection_signal): Remove; no longer needed
1911 now that we use sigaction.
1912 (x_connection_closed): No need to mess with sigmask now.
1913 (x_initialize): No need to reset SIGPIPE handler here, since
1914 init_signals does this for us now.
1916 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
1918 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
1919 background rect may be larger (Bug#12245).
1921 2012-09-23 Chong Yidong <cyd@gnu.org>
1923 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
1925 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
1927 * .gdbinit: Just stop at fatal_error_backtrace.
1928 See Stefan Monnier's request in
1929 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
1930 Remove no-longer-used query of system type.
1932 2012-09-22 Chong Yidong <cyd@gnu.org>
1934 * search.c (Freplace_match): Doc fix (Bug#12325).
1936 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
1938 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
1939 (Fline_end_position): Doc fix.
1941 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
1943 2012-09-22 Chong Yidong <cyd@gnu.org>
1945 * dispextern.h (struct image_type): Add new slot, storing a type
1946 initialization function.
1948 * image.c (define_image_type): Call the image initializer function
1949 if it is defined. Arguments and return value changed.
1950 (valid_image_p, make_image): Callers changed.
1951 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
1952 (gif_type, imagemagick_type, svg_type, gs_type):
1953 Add initialization functions.
1954 (Finit_image_library): Call lookup_image_type.
1955 (CHECK_LIB_AVAILABLE): Macro deleted.
1956 (lookup_image_type): Call define_image_type here, rather than via
1957 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
1958 (syms_of_image): Move define_image_type calls for xbm_type and
1959 pbm_type to lookup_image_type.
1961 2012-09-22 Eli Zaretskii <eliz@gnu.org>
1963 * keyboard.c (timer_check_2): Move calculation of 'timers' and
1964 'idle_timers' from here ...
1965 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
1966 lists, to avoid infloops when the timer does something stupid,
1967 like reinvoke itself with the same or smaller time-out.
1970 2012-09-22 Martin Rudalics <rudalics@gmx.at>
1972 * window.c (Fsplit_window_internal): Handle only Qt value of
1973 Vwindow_combination_limit separately.
1974 (Qtemp_buffer_resize): New symbol.
1975 (Vwindow_combination_limit): New default value.
1978 2012-09-22 Eli Zaretskii <eliz@gnu.org>
1980 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
1981 the new overlay string. (Bug#10159)
1983 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
1985 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
1986 or that fprintf is async-signal-safe. POSIX doesn't require
1989 2012-09-22 Chong Yidong <cyd@gnu.org>
1991 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
1994 2012-09-22 Kenichi Handa <handa@gnu.org>
1996 * composite.c (composition_reseat_it): Handle the case that a
1997 grapheme cluster is not covered by a single font (Bug#12352).
1999 2012-09-21 Chong Yidong <cyd@gnu.org>
2001 * image.c (define_image_type): Avoid adding duplicate types to
2002 image_types (Bug#12463). Suggested by Jörg Walter.
2004 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2006 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
2007 (print_load_command_name): Add case LC_DATA_IN_CODE.
2008 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
2010 2012-09-21 Glenn Morris <rgm@gnu.org>
2012 * eval.c (Frun_hook_with_args_until_success)
2013 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
2015 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
2017 * fileio.c (Ffile_selinux_context): Only call freecon when
2018 lgetfilecon succeeded.
2019 (Fset_file_selinux_context): Likewise. (Bug#12444)
2021 2012-09-21 Eli Zaretskii <eliz@gnu.org>
2023 * xdisp.c (try_window_reusing_current_matrix): Under bidi
2024 reordering, locate the cursor by calling set_cursor_from_row; if
2025 that fails, clear the desired glyph matrix before returning a
2026 failure indication to the caller. Fixes leaving garbled display
2027 when fast scrolling with a down-key. (Bug#12403)
2028 (compute_stop_pos_backwards): Fix a typo that caused crashes while
2029 scrolling through multibyte text.
2031 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
2033 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
2034 calling mark_vectorlike since that's the one that marks the window.
2035 (mark_discard_killed_buffers): Mark the final cdr.
2036 * window.h (struct window): Move prev/next_buffers to the
2037 non-standard fields.
2038 * window.c (make_window): Initialize prev/next_buffers manually.
2040 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
2042 Omit unused arg EXPECTED from socket hooks.
2043 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
2044 * nsterm.m (ns_term_init):
2045 * termhooks.h (struct terminal.read_socket_hook):
2046 * w32inevt.c (w32_console_read_socket):
2047 * w32term.c (w32_read_socket):
2048 * xterm.c (XTread_socket):
2049 Omit unused arg EXPECTED. All callers changed.
2050 (store_user_signal_events): Return void, not int, since callers no
2051 longer care about the return value. All uses changed.
2053 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
2055 * w32gui.h (XParseGeometry): Do not declare.
2057 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
2059 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
2060 Ignore 'expected'. See Eli Zaretskii in
2061 <http://bugs.gnu.org/12471#8> (last line).
2063 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
2064 (XParseGeometry): Now static. Substitute extremal values for
2065 values that are out of range.
2067 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
2069 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
2071 * nsfns.m (XParseGeometry): Remove.
2072 (Fx_create_frame): Call x_set_offset to correctly interpret
2073 top_pos in geometry.
2075 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
2076 (Fx_parse_geometry): If there is a space in string, call
2077 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
2079 2012-09-17 Eli Zaretskii <eliz@gnu.org>
2081 * search.c (scan_buffer): Use character positions in calls to
2082 region_cache_forward and region_cache_backward, not byte
2083 positions. (Bug#12196)
2085 * w32term.c (w32_read_socket): Set pending_signals to 1, like
2086 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
2088 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
2089 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
2090 emacs_blocked_malloc, now deleted.
2092 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
2094 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
2095 The workaround was for improving performance on Solaris 2.4, but
2096 is getting in the way now. Emacs will still work if someone is
2097 still running Solaris 2.4 in a museum somewhere; Sun dropped
2098 support for Solaris 2.4 in 2003.
2099 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
2100 * process.c (create_process) [HAVE_WORKING_VFORK]:
2101 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
2102 since Emacs no longer uses vfork on that platform.
2104 2012-09-17 Glenn Morris <rgm@gnu.org>
2106 * emacs.c: Use COPYRIGHT.
2108 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
2110 Remove configure's --without-sync-input option (Bug#12450).
2111 When auditing signal-handling in preparation for cleaning it up,
2112 I found that SYNC_INPUT has race conditions and would be a real
2113 pain to fix. Since it's an undocumented and deprecated
2114 configure-time option, now seems like a good time to remove it.
2115 Also see <http://bugs.gnu.org/11080#16>.
2116 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
2117 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
2118 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
2119 (malloc_hysteresis):
2120 (check_depth) [XMALLOC_OVERRUN_CHECK]:
2121 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
2122 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
2123 (dont_register_blocks, bytes_used_when_reconsidered)
2124 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
2125 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
2126 [!SYSTEM_MALLOC && !SYNC_INPUT]:
2127 Remove. All uses removed.
2128 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
2129 implementation, one that depends on whether the new macro
2130 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
2132 * atimer.c (run_timers, handle_alarm_signal):
2133 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
2134 (handle_async_input, process_pending_signals)
2135 (handle_input_available_signal, init_keyboard):
2136 * nsterm.m (ns_read_socket):
2137 * process.c (wait_reading_process_output):
2138 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
2139 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
2141 * xterm.c (XTread_socket):
2143 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
2144 * eval.c (handling_signal): Remove. All uses removed.
2145 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
2146 All uses replaced with the SYNC_INPUT version.
2147 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
2149 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2152 * font.c (Ffont_shape_gstring): Remove unused local.
2154 2012-09-16 Glenn Morris <rgm@gnu.org>
2156 * Makefile.in (clean): No longer run nextstep's clean.
2158 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
2160 (ns-app): Move here from ns.mk, and simplify.
2161 (clean): Simplify nextstep entry.
2162 * ns.mk: Remove file.
2164 2012-09-17 Kenichi Handa <handa@gnu.org>
2166 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
2167 not covert the last few charactes.
2169 2012-09-16 Kenichi Handa <handa@gnu.org>
2171 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
2172 here, but just check the validity of glyphs in the glyph-string.
2174 2012-09-16 Martin Rudalics <rudalics@gmx.at>
2176 * window.c (Fwindow_parameter, Fset_window_parameter):
2177 Accept any window as argument (Bug#12452).
2179 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
2181 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
2182 to ns_term_init to avoid memory leak.
2184 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
2185 explicit retain/release.
2186 (ns_term_init): Only allow one display. Initialize outerpool and
2189 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
2191 Port _setjmp fix to POSIXish hosts as well as Microsoft.
2192 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
2193 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
2194 the Microsoft problem in a different way, by altering ../nt/config.nt.
2196 2012-09-15 Eli Zaretskii <eliz@gnu.org>
2211 * w16select.c: Remove inclusion of setjmp.h, as it is now included
2212 by lisp.h. This completes removal of setjmp.h inclusion
2213 erroneously announced in the previous commit. (Bug#12446)
2215 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
2218 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
2219 not defined as a macro. The latter happens on MS-Windows.
2222 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
2224 Port better to POSIX hosts lacking _setjmp (Bug#12446).
2225 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
2226 Some instances of '#include <setjmp.h>' removed, if the
2227 only reason for the instance was because "lisp.h" was included.
2228 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
2229 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
2230 and _longjmp with the new symbols. Emacs already uses _setjmp if
2231 available, so this change affects only POSIXish hosts that have
2232 sigsetjmp but not _setjmp, such as some versions of Solaris and
2233 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
2234 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
2235 (png_load_body) [HAVE_PNG]:
2236 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
2237 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
2238 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
2239 since PNG requires jmp_buf. This is the only exception to the
2240 general rule that we now use sys_setjmp and sys_longjmp.
2241 This exception is OK since this code does not change the signal
2242 mask or longjmp out of a signal handler.
2244 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
2246 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
2247 Include "syssignal.h", for 'main_thread'.
2249 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
2251 Avoid out-of-range marker position (Bug#12426).
2252 * insdel.c (replace_range, replace_range_2):
2253 Adjust markers before overlays, as suggested by comments.
2254 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
2255 Remove redundant check before calling offset_intervals.
2257 2012-09-14 Martin Rudalics <rudalics@gmx.at>
2259 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
2260 current buffer (Bug#12387).
2262 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
2264 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
2266 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
2268 Use a more backwards-compatible timer format (Bug#12430).
2269 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
2270 vector element, not from the 4th, since PSECS is now at the end.
2271 (Fcurrent_idle_time): Doc fix.
2273 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
2275 Function to mark objects and remove killed buffers at once.
2276 * alloc.c (discard_killed_buffers): Rename to ...
2277 (mark_discard_killed buffers) ... new name. Add marking
2278 of remaining objects. Fix comment. Adjust users.
2279 (mark_object): Do not touch frame buffer lists here.
2280 * frame.c (delete_frame): Reset frame buffer lists here.
2282 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
2284 Better workaround for GNOME bug when --enable-gcc-warnings.
2285 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
2286 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
2287 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
2289 Simplify SIGIO usage (Bug#12408).
2290 The code that dealt with SIGIO was crufty and confusing, e.g., it
2291 played tricks like "#undef SIGIO" but these tricks were not used
2292 consistently. Simplify mostly by not #undeffing standard symbols,
2293 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
2294 or not as we please) rather than "defined SIGIO" (standard symbol
2295 that we probably shouldn't #undef).
2296 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
2297 Modules that need it can include it.
2298 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
2299 * dispextern.h (ignore_sigio): New decl.
2300 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
2301 unconditionally, since it's now a no-op if !USABLE_SIGIO.
2302 * emacs.c (shut_down_emacs):
2303 * keyboard.c (kbd_buffer_store_event_hold):
2304 Use ignore_sigio rather than invoking 'signal' directly.
2305 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
2307 (FIONREAD, SIGIO): Do not #undef.
2308 (tty_read_avail_input): Use #error rather than a syntax error.
2309 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
2310 for I_PIPE, used by SETUP_SLAVE_PTY.
2311 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
2312 * sysdep.c (croak): Remove; no longer needed. This bit of
2313 temporary code, with Fred N. Fish's comment that it's temporary,
2314 has been in Emacs since at least 1992!
2315 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
2316 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
2317 * syssignal.h (croak): Remove decl.
2318 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
2319 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
2320 now that we're termios-only.
2321 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
2322 * term.c (dissociate_if_controlling_tty): Use #error rather than
2325 Work around GCC and GNOME bugs when --enable-gcc-warnings.
2326 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
2327 to work around GNOME bug 683906.
2328 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
2329 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
2330 This works around GCC bug 54561.
2332 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
2334 More fixes for 'volatile' and setjmp/longjmp.
2335 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
2336 * image.c (struct png_load_context) [HAVE_PNG]: New type.
2337 (png_load_body) [HAVE_PNG]:
2338 (jpeg_load_body) [HAVE_JPEG]:
2339 New function, with most of the old parent function's body.
2340 (png_load) [HAVE_PNG]:
2341 (jpeg_load) [HAVE_JPEG]:
2342 Invoke the new function, to avoid longjmp munging our locals.
2343 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
2344 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
2345 longjmp is passed 2, as the C standard doesn't guarantee this.
2346 Instead, store the failure code into mgr->failure_code.
2348 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
2350 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
2351 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
2352 (syms_of_keyboard): Remove support for unread-command-char.
2354 2012-09-12 Eli Zaretskii <eliz@gnu.org>
2356 * w32proc.c (sys_kill): If PID is our process ID and the signal is
2357 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
2358 violation. (Bug#12426)
2360 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
2362 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
2364 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
2366 * eval.c: Add `inhibit-debugger'.
2367 (Qinhibit_debugger): New symbol.
2368 (call_debugger): Bind it instead of Qdebug_on_error.
2369 (maybe_call_debugger): Test Vinhibit_debugger.
2370 (syms_of_eval): Define inhibit-debugger.
2371 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
2372 (syms_of_xdisp): Remove inhibit-debug-on-message.
2374 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
2376 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
2377 If a nonvolatile local variable is written before a _longjmp to
2378 the frame containing the variable, and is read after the _longjmp,
2379 the value read is indeterminate. Some local variables of type
2380 'struct handler' and 'struct catchtag' are used in this way, so
2381 mark each of their slots as volatile if the slot can be set before
2382 _longjmp and read afterwards.
2383 * lisp.h (struct handler): var and chosen_clause are now volatile.
2384 (struct catchtag): val, next, and pdlcount are now volatile.
2386 * bidi.c (bidi_push_it, bidi_pop_it):
2387 * fns.c (copy_hash_table):
2388 * image.c (define_image_type):
2389 * keyboard.c (kbd_buffer_store_event_hold):
2390 * process.c (Fprocess_send_eof):
2391 * xfaces.c (x_create_gc) [HAVE_NS]:
2392 * xgselect.c (xg_select):
2393 Prefer assignment to memcpy when either will do.
2395 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
2396 Use pointer-to-a-pointer to simplify and avoid a NILP check each
2397 time an item is removed. No need to mark this function 'inline';
2398 the compiler knows better than we do.
2400 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
2402 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
2403 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
2404 to change_frame_size (Bug#12388).
2405 (windowDidResize:): Pass YES to updateFrameSize.
2407 * nsterm.h: Add delay parameter to updateFrameSize.
2409 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
2411 Discard killed buffers from deleted window and frame objects.
2412 This reduces an amount of references to killed buffers and
2413 helps GC to reclaim them faster.
2414 * alloc.c (discard_killed_buffers): New function.
2415 (mark_object): Use it for deleted windows and frames.
2416 (mark_object): If symbol's value is set up for a killed buffer
2417 or deleted frame, restore its global binding.
2418 * data.c (swap_in_global_binding): Add GC notice.
2419 (swap_in_symval_forwarding): Use convenient set_blv_where.
2420 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
2421 * window.h: ... to here.
2423 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
2425 Convenient macro to check whether the buffer is live.
2426 * buffer.h (BUFFER_LIVE_P): New macro.
2427 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
2428 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
2430 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2432 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
2433 composition cases (Bug#12364).
2435 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
2436 overhang of succeeding glyphs overlapping box cursor.
2438 * w32term.c (x_draw_glyph_string): Likewise.
2440 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
2442 Simplify, document, and port floating-point (Bug#12381).
2443 The porting part of this patch fixes bugs on non-IEEE platforms
2444 with frexp, ldexp, logb.
2445 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
2447 * floatfns.c: Simplify discussion of functions that Emacs doesn't
2448 support, by removing commented-out code and briefly listing the
2449 C89 functions excluded. The commented-out stuff was confusing
2450 maintenance, e.g., we thought we needed cbrt but it was commented out.
2451 (logb): Remove decl; no longer needed.
2452 (isfinite): New macro, if not already supplied.
2453 (isnan): Don't replace any existing macro.
2454 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
2455 are present on all C89 platforms.
2456 (Ffrexp): Do not special-case zero, as frexp does the right thing
2458 (Flogb): Do not use logb, as it doesn't have the desired meaning
2459 on hosts that use non-base-2 floating point. Instead, stick with
2460 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
2461 frexp, to avoid getting an unspecified result.
2463 * xdisp.c (Qinhibit_debug_on_message): Now static.
2465 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
2467 * nsterm.m (ns_update_begin): Set clip path to whole view by using
2468 NSBezierPath (Bug#12131).
2470 2012-09-10 Chong Yidong <cyd@gnu.org>
2472 * fns.c (Fdelq, Fdelete): Doc fix.
2474 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
2476 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
2477 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
2479 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
2481 * lisp.h (make_lisp_ptr): New macro to replace XSET.
2482 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
2485 2012-09-09 Eli Zaretskii <eliz@gnu.org>
2487 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
2488 left fringe if the window has a left margin. This avoids leaving
2489 traces of the cursor because its leftmost pixel is not drawn over.
2491 * dispnew.c (update_window_line): When the left margin area of a
2492 screen line is updated, set the redraw_fringe_bitmaps_p flag of
2493 that screen line. (Bug#12277)
2495 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
2497 Assume C89 or later for math functions (Bug#12381).
2498 This simplifies the code, and makes it a bit smaller and faster,
2499 and (most important) makes it easier to clean up signal handling
2500 since we can stop worring about floating-point exceptions in
2501 library code. That was a problem before C89, but the problem
2502 went away many years ago on all practical Emacs targets.
2503 * data.c, image.c, lread.c, print.c:
2504 Don't include <math.h>; no longer needed.
2505 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
2506 might be autoconfigured, as that never happens.
2508 * doprnt.c (DBL_MAX_10_EXP):
2509 * print.c (DBL_DIG):
2510 Remove. C89 or later always defines these.
2511 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
2512 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
2513 (arith_error, domain_error, domain_error2):
2514 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
2515 no longer needed -- we simply return what C returns. All uses removed.
2516 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
2518 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
2519 Remove. All uses expanded, as these macros are no longer used
2520 more than once and are now more trouble than they're worth.
2521 (Ftan): Use tan, not sin / cos.
2522 (Flogb): Assume C89 frexp.
2523 (fmod_float): Assume C89 fmod.
2524 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
2525 (init_floatfns): Remove. All uses removed.
2527 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2529 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
2530 compositeToPoint for OSX < 10.6 (Bug#12390).
2532 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
2534 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
2535 This produces more-accurate results.
2537 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2539 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
2540 changes (Bug#12088).
2542 2012-09-08 Chong Yidong <cyd@gnu.org>
2544 * syntax.c (Fstring_to_syntax): Doc fix.
2546 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2548 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
2549 in the internal border.
2550 (x_set_window_size): Remove static variables and their usage.
2551 (ns_redraw_scroll_bars): Fix NSTRACE arg.
2552 (ns_after_update_window_line, ns_draw_fringe_bitmap):
2553 Remove fringe/internal border adjustment (Bug#11052).
2554 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
2555 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
2556 (ns_fix_rect_ibw): Remove.
2557 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
2558 (ns_dumpglyphs_box_or_relief): Ditto.
2559 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
2561 (ns_dumpglyphs_image): Ditto.
2562 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
2564 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
2565 their usage. Add fringe_extended_p and its use as in other terms.
2566 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
2567 scroll bar was removed.
2568 (updateFrameSize): New function.
2569 (windowDidResize): Move code to updateFrameSize and call it.
2571 * nsterm.h (EmacsView): Add updateFrameSize.
2573 2012-09-07 Chong Yidong <cyd@gnu.org>
2575 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
2577 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
2579 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
2581 More signal-handler cleanup (Bug#12327).
2582 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
2583 Problem introduced when merging patches. Noted by Eli Zaretskii in
2584 <http://bugs.gnu.org/12327#67>.
2585 * floatfns.c: Comment fix.
2586 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
2587 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
2588 and anyway the declaration is harmless even if SIGDANGER is not defined.
2589 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
2590 defined BROKEN_FIONREAD). systty.h formerly did this, but other
2591 source files not surprisingly expected syssignal.h to define, or
2592 not define, SIGIO, and it's cleaner to do it that way, for consistency.
2593 Include <sys/ioctl.h>, for FIONREAD.
2594 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
2595 This eliminates a problem whereby other files mysteriously had
2596 to include "syssignal.h" before including "systty.h" if they
2597 wanted to use "#ifdef SIGIO".
2599 2012-09-07 Eli Zaretskii <eliz@gnu.org>
2601 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
2603 * w32.c (sigemptyset): Empty the set.
2604 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
2606 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
2608 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
2610 * alloc.c (mark_buffer): Revert unsafe marking optimization.
2611 (mark_object): Likewise for frame objects.
2613 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
2615 * syssignal.h (handle_on_main_thread): Always declare,
2616 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
2617 This ports to platforms without HAVE_PTHREAD.
2619 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
2621 Signal-handler cleanup (Bug#12327).
2622 Emacs's signal handlers were written in the old 4.2BSD style with
2623 sigblock and sigmask and so forth, and this led to some
2624 inefficiencies and confusion. Rewrite these to use
2625 pthread_sigmask etc. without copying signal sets around. Also,
2626 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
2627 'signal', and instead use functions that do not attempt to take
2628 over the system name space. This patch causes Emacs's text
2629 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
2630 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
2631 Do not include <signal.h> or "syssignal.h", as these
2632 modules do not use signals.
2633 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
2634 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
2635 Do not include <signal.h>, as "syssignal.h" does that for us now.
2636 * atimer.c (sigmask_atimers): New function.
2637 (block_atimers, unblock_atimers): New functions,
2638 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
2640 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
2641 no longer needed here.
2642 * emacs.c (main): Inspect existing signal handler with sigaction,
2643 so that there's no need to block and unblock SIGHUP.
2644 * sysdep.c (struct save_signal): New member 'action', replacing
2645 old member 'handler'.
2646 (save_signal_handlers, restore_signal_handlers):
2647 Use sigaction instead of 'signal' to save and restore.
2648 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
2649 New function. All users of 'signal' modified to use set_sighandler
2650 if they're writeonly, and to use sys_signal if they're read+write.
2651 (emacs_sigaction_init, forwarded_signal): New functions.
2652 (sys_signal): Remove. All uses replaced by calls to sigaction
2653 and emacs_sigaction_init, or by direct calls to 'signal'.
2654 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
2655 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
2656 all uses replaced by pthread_sigmask etc. calls.
2657 * syssignal.h: Include <signal.h>.
2658 (emacs_sigaction_init, forwarded_signal): New decls.
2659 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
2660 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
2661 (sigmask, sys_sigmask): Remove; no longer needed.
2662 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
2663 (sigblock, sigunblock, sigfree):
2664 (sigsetmask) [!defined sigsetmask]:
2665 Remove. All uses replaced by pthread_sigmask.
2666 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
2667 no longer need to be replaced, and its typical old uses
2668 are now done via emacs_sigaction_init and sigaction.
2669 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
2670 (sys_sigdel): Remove; unused.
2671 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
2673 2012-09-06 Eli Zaretskii <eliz@gnu.org>
2675 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
2676 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
2678 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
2680 Explicitly mark buffer_defaults and buffer_local_symbols.
2681 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
2682 mark_local_symbols here.
2683 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
2684 since special buffers aren't marked here any more.
2685 (allocate_buffer): Chain new buffer with all_buffers here...
2686 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
2688 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
2689 (syms_of_buffer): Remove staticpro of the above.
2690 (init_buffer_once): Set names for buffer_defaults and
2691 buffer_local_symbols.
2693 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
2695 Use bool for booleans in font-related modules.
2696 * font.c (font_intern_prop, font_style_to_value)
2697 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
2698 (generate_otf_features, font_check_otf_features, font_check_otf)
2699 (font_match_p, font_list_entities, font_at):
2700 * fontset.c (fontset_id_valid_p, reorder_font_vector
2701 (fontset_find_font, Fset_fontset_font)
2702 (face_suitable_for_char_p) [0]:
2703 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
2704 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
2705 (m17n_flt_initialized, ftfont_shape_by_flt):
2706 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
2707 * nsfont.m (nsfont_draw):
2708 * w32font.c (w32font_draw):
2709 * w32term.c (x_draw_glyphless_glyph_string_foreground):
2710 Use bool for booleans.
2711 * font.h: Adjust to above API changes.
2712 (struct font, struct font_driver, struct font_driver_list):
2713 Use bool for booleans.
2714 (struct font): Remove useless member encoding_type.
2716 * fontset.c, xftfont.c: Omit unnecessary static decls.
2718 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
2720 * alloc.c (mark_object): Revert window marking code
2721 since it's unsafe for the Fset_window_configuration.
2723 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
2725 Fix race conditions with signal handlers and errno (Bug#12327).
2726 Be more systematic about preserving errno whenever a signal
2727 handler returns, even if it's not in the main thread. Do this by
2728 renaming signal handlers to distinguish between signal delivery
2729 and signal handling. All uses changed.
2730 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
2731 * data.c (deliver_arith_signal): Rename from arith_error.
2732 * dispnew.c (deliver_window_change_signal): Rename from
2733 window_change_signal.
2734 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
2735 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
2736 * keyboard.c (deliver_input_available_signal): Rename from
2737 input_available_signal.
2738 (deliver_user_signal): Rename from handle_user_signal.
2739 (deliver_interrupt_signal): Rename from interrupt_signal.
2740 * process.c (deliver_pipe_signal): Rename from send_process_trap.
2741 (deliver_child_signal): Rename from sigchld_handler.
2742 * atimer.c (handle_alarm_signal):
2743 * data.c (handle_arith_signal):
2744 * dispnew.c (handle_window_change_signal):
2745 * emacs.c (handle_fatal_signal, handle_danger_signal):
2746 * keyboard.c (handle_input_available_signal):
2747 * keyboard.c (handle_user_signal, handle_interrupt_signal):
2748 * process.c (handle_pipe_signal, handle_child_signal):
2749 New functions, with the actual signal-handling code taken from the
2750 original respective signal handlers, sans the sporadic attempts to
2751 preserve errno, since that's now done by handle_on_main_thread.
2752 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
2753 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
2754 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2756 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2757 Move initialization of main_thread to sysdep.c's init_signals.
2758 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
2759 our usage, and simplifies the mainline code.
2760 (record_child_status_change): New static function, as a helper
2761 for handle_child_signal, and with most of the old child handler's
2763 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
2764 (handle_child_signal): Use the above.
2765 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2766 Moved here from emacs.c.
2767 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
2768 code moved here from emacs.c's main function.
2769 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
2770 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
2771 This lets callers save and restore errno properly.
2773 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2775 Remove redundant or unused things here and there.
2776 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.

2779 * frame.h (struct terminal, struct font_driver_list):
2780 Remove redundant declarations.
2781 * window.h (Qleft, Qright): Likewise.
2783 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2785 Do not mark objects from deleted buffers, windows and frames.
2786 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
2787 (mark_object): Likewise for windows and frames.
2789 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2791 * alloc.c (valid_lisp_object_p): Treat killed buffers,
2792 buffer_defaults and buffer_local_symbols as valid objects.
2793 Return special value to denote them.
2795 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
2797 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
2798 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
2799 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
2800 (file_name_absolute_p, Fsubstitute_in_file_name):
2801 (check_executable, check_writable, Ffile_accessible_directory_p)
2802 (Fset_file_selinux_context, Fdefault_file_modes)
2803 (Finsert_file_contents, choose_write_coding_system)
2804 (Fwrite_region, build_annotations, a_write, e_write)
2806 * filelock.c (boot_time_initialized, get_boot_time)
2807 (get_boot_time_1, lock_file_1, within_one_second):
2808 * floatfns.c (in_float):
2809 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
2810 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
2811 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
2812 * lisp.h (struct Lisp_Hash_Table.cmpfn):
2813 * window.c (compare_window_configurations):
2814 Use bool for booleans.
2815 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
2816 (Fdefault_file_modes): Now mode_t, not int, for modes.
2817 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
2818 (internal_delete_file): Now returns void, not a (boolean) int,
2819 since nobody was looking at the return value.
2820 * lisp.h, window.h: Adjust to above API changes.
2822 * xdisp.c (set_message): Simplify and reindent last change.
2824 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
2826 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
2828 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
2830 * eval.c (call_debugger): Make the function non-static so that we
2831 can call it from set_message.
2833 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
2834 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
2836 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2838 Give more-useful info on a fatal error (Bug#12328).
2839 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
2840 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
2841 of doing the work ourselves.
2842 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
2843 do most of the work.
2844 (fatal_error_backtrace): New function, taken from the guts
2845 of the old fatal_error_signal, but with a new option to output
2847 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
2848 info about the signal than just its number.
2849 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
2850 * sysdep.c: Include <execinfo.h>
2851 (emacs_backtrace): New function, taken partly from the previous
2852 code of the 'die' function.
2853 (emacs_abort): Call fatal_error_backtrace rather than abort.
2855 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
2857 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
2858 eager (load-time) macro-expansion.

2861 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2863 Simplify redefinition of 'abort' (Bug#12316).
2864 Do not try to redefine the 'abort' function. Instead, redo
2865 the code so that it calls 'emacs_abort' rather than 'abort'.
2866 This removes the need for the NO_ABORT configure-time macro
2867 and makes it easier to change the abort code to do a backtrace.
2868 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
2869 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
2870 Remove; sysdep.c's emacs_abort now takes its place.
2871 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
2872 'abort' changed to use 'emacs_abort'.
2873 * msdos.c (dos_abort) [defined abort]: Remove; not used.
2874 (abort) [!defined abort]: Rename to ...
2875 (emacs_abort): ... new name.
2876 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
2877 the place of the old 'abort' in emacs.c.
2878 * w32.c, w32fns.c (abort): Do not #undef.
2879 * w32.c (emacs_abort): Rename from w32_abort.
2881 2012-09-04 Eli Zaretskii <eliz@gnu.org>
2883 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
2884 offsets[j].dv, since the y axis of the screen coordinates points
2885 down, while the y axis of the font definition coordinates points
2886 up. This fixes display of Arabic diacritics such as KASRA and
2887 KASRATAN. (Bug#11860)
2889 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2891 Be more systematic about _setjmp vs setjmp.
2892 * alloc.c (test_setjmp, mark_stack):
2893 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
2894 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
2895 (png_load, my_error_exit, jpeg_load):
2896 * process.c (send_process_trap, send_process):
2897 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
2898 The underscored versions are up to 30x faster on some hosts.
2899 Formerly, the code used setjmp+longjmp sometimes and
2900 _setjmp+_longjmp at other times, with no particular reason to
2901 prefer setjmp+longjmp.
2903 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
2905 Fix minor problem found by static checking.
2906 * buffer.c (Fdelete_all_overlays): Return nil.
2908 2012-09-03 Martin Rudalics <rudalics@gmx.at>
2910 * buffer.c (Fdelete_all_overlays): New function.
2912 2012-09-03 Chong Yidong <cyd@gnu.org>
2914 * gtkutil.c: Add extern decl for Qxft.
2916 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

2930 All callers changed.
2931 * eval.c (interactive_p): Omit always-true boolean argument
2932 EXCLUDE_SUBRS_P. All callers changed.
2933 * dispextern.h, lisp.h: Reflect above API changes.
2934 * firstfile.c (dummy): Use the address of 'main', whose signature
2935 won't change, instead of the address of 'initialize', whose
2936 signature just changed from int to bool.
2937 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
2938 * msdos.c (fatal_error_in_progress): ... from here.
2939 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
2941 (redisplay_internal, unwind_redisplay): Simply clear
2942 REDISPLAYING_P when unwinding, instead of saving its previous,
2943 always-false value and then restoring it.
2945 Clean up some extern decls.
2946 Mostly, this hoists extern decls out of .c files and into .h files.
2947 That way, we're more likely to catch errors if the interfaces change.
2948 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
2949 declare xg_mark_data.
2950 * dispextern.h (x_frame_parm_handlers):
2952 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
2953 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)

2968 * xfont.c (x_clear_errors):
2969 * xterm.c (x_frame_parm_handlers):
2970 Remove now-redundant extern decls.
2971 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
2972 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
2974 * xfaces.c: Remove unnecessary static decls.
2975 * xterm.c (updating_frame): Remove decl of nonexistent object.
2977 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
2978 when building globals.h, as the objects that are not built on
2979 this host are not needed to compile C files on this host.
2981 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
2983 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

2996 (format_time_string, general_insert_function)
2997 (make_buffer_string, make_buffer_string_both)
2998 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):
2999 * insdel.c (check_markers, gap_left, adjust_markers_for_insert)

3009 (get_property_and_range, compare_string_intervals)
3010 (set_intervals_multibyte_1, set_intervals_multibyte):
3011 * keyboard.c (decode_timer):
3012 Use bool for boolean.
3013 * intervals.h, lisp.h, systime.h: Reflect above API changes.
3014 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
3016 2012-09-02 Chong Yidong <cyd@gnu.org>
3018 * keymap.c (push_key_description): Print M-TAB as C-M-i
3021 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
3023 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
3024 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

3029 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
3031 2012-09-01 Eli Zaretskii <eliz@gnu.org>
3033 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
3034 more than one grapheme cluster passed to the shaper: compute the
3035 offset adjustment values separately for each cluster. (Bug#11860)
3037 * image.c: Restore mistakenly removed inclusion of w32.h. Without
3038 it, GCC doesn't see prototypes of w32_delayed_load, and complains
3039 about implicit conversions from integer to pointer.
3041 2012-09-01 Daniel Colascione <dancol@dancol.org>
3043 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
3044 system used too early.
3046 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
3048 Better seed support for (random).

3077 * process.c: Include TERM_HEADER instead of listing all possible
3078 window-system headers.
3080 * nsterm.h: Remove declarations now in frame.h.
3081 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
3083 * menu.c: Include TERM_HEADER instead of listing all possible
3084 window-system headers.
3086 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
3089 * keyboard.c: Include TERM_HEADER instead of listing all possible
3090 window-system headers.
3092 * image.c: Include TERM_HEADER instead of listing all possible
3093 window-system headers. Declare Vlibrary_cache when compiling for
3096 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
3097 window system declarations.
3099 * frame.h: Move common functions here: set_frame_menubar,
3100 x_set_window_size, x_sync, x_get_focus_frame,
3101 x_set_mouse_position, x_set_mouse_pixel_position,
3102 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

3123 the current window system; include in list of objects to link into
3126 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
3128 Remove mark_ttys function and fix tty_display_info initialization.
3129 * lisp.h (mark_ttys): Remove prototype.
3130 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
3131 to mark_ttys because all possible values of 'top_frame' slot are
3132 the frames which are reachable from Vframe_list.
3133 * term.c (mark_ttys): Remove.
3134 (init_tty): Safely initialize 'top_frame' slot with Qnil.
3136 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>

3141 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
3142 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
3143 bitfields from unsigned char to unsigned.

3151 2012-08-30 Jan Djärv <jan.h.d@swipnet.se>
3153 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it

3156 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
3158 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
3159 for GCC 4.7.1 x86-64.
3161 2012-08-30 Glenn Morris <rgm@gnu.org>
3163 * lread.c (init_lread): For out-of-tree builds, only add the
3164 source directory's site-lisp dir to the load-path if it exists,
3165 consistent with in-tree builds. (Bug#12302)
3167 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
3169 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize

3171 (windowShouldClose:): Set window_closed.
3172 (dealloc): New member, free button_values.
3173 (process_dialog:): Make member function. Remove window argument,
3174 replace window with self. Count buttons and allocate and store values
3176 (addButton:value:row:): value is int with the name tag. Call setTag
3177 with tag. Remove return self, declare return value as void.
3178 (addString:row:): Remove return self, declare return value as void.
3179 (addSplit): Remove return self, declare return value as void.
3180 (clicked:): Remove return self, declare return value as void.
3181 Set dialog_return to button_values[seltag]. Code formatting change.
3182 (initFromContents:isQuestion:): Adjust call to process_dialog.
3183 Code formatting change.
3184 (timeout_handler:): Set timer_fired to YES.
3185 (runDialogAt:): Set timer_fired to NO.
3186 Handle click on close button as quit.
3188 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
3189 Add window_closed and button_values. Add void as return value for
3190 add(Button|String|Split). addButton takes int instead of Lisp_Object.
3191 Add process_dialog as new member.
3193 2012-08-28 Eli Zaretskii <eliz@gnu.org>
3195 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
3196 is not one of the heaps we manage. (Bug#12242)
3198 2012-08-28 Glenn Morris <rgm@gnu.org>
3200 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)
3202 2012-08-28 Martin Rudalics <rudalics@gmx.at>

3212 if the buffer is dead.
3213 (Fother_buffer, other_buffer_safely): Remove redundant
3216 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
3218 Always use set_buffer_if_live to restore original buffer at unwind.
3219 * buffer.h (record_unwind_current_buffer): New function.
3220 * bytecode.c, dispnew.c, editfns.c, fileio.c, fns.c, insdel.c:

3227 Fix usage of set_buffer_internal.
3228 * buffer.h (set_buffer_internal): Make it BUFFER_INLINE.
3229 * buffer.c (set_buffer_if_live): Use set_buffer_internal.

3256 (change_frame_size_1, sit_for):
3257 Use bool for boolean.
3258 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
3259 and remove last int (actually boolean) argument, which was always 0.
3260 All callers changed.
3261 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
3262 * dispextern.h (struct composition_it): Use bool for boolean.
3263 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
3264 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
3265 * dired.c (file_name_completion):
3266 Use bool for boolean. (This was missed in an earlier change.)
3268 2012-08-27 Martin Rudalics <rudalics@gmx.at>
3270 * window.c (Fset_window_configuration): Revert first part of
3273 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
3275 * nsterm.h (NSPanel): New class variable dialog_return.
3277 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
3278 Initialize dialog_return.
3279 (windowShouldClose:): Use stop instead of stopModalWithCode.
3280 (clicked:): Ditto, and also set dialog_return (Bug#12258).
3281 (timeout_handler:): Use stop instead of abortModal. Send a dummy
3283 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when
3286 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>

3328 Use bool for booleans.
3329 * coding.h, lisp.h: Reflect above API changes.
3330 * coding.c: Remove unnecessary static function decls.
3331 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
3332 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
3333 not a boolean 'int', since callers never look at the return value.
3334 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
3335 * coding.h (decoding_buffer_size, encoding_buffer_size)
3336 (emacs_mule_string_char): Remove unused extern decls.
3337 (struct iso_2022_spec, struct coding_system):

3339 (struct emacs_mule_spec): Remove unused field 'full_support'.
3340 All initializations removed.
3341 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
3343 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
3345 Fix spare memory change (Bug#12286).
3346 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
3347 (valid_lisp_object_p): Likewise.
3349 2012-08-27 Martin Rudalics <rudalics@gmx.at>
3351 * window.c (Fset_window_configuration): Record any window's old
3352 buffer if it's replaced (see Bug#8789). If the new current
3353 buffer doesn't appear in the selected window, go to its old
3356 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
3358 Special MEM_TYPE_SPARE to denote reserved memory.
3359 * alloc.c (enum mem_type): New memory type.
3360 (refill_memory_reserve): Use new type for spare memory.
3361 This prevents live_cons_p and live_string_p from incorrect
3362 detection of uninitialized objects from spare memory as live.
3364 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
3367 * Makefile.in (.PHONY): versioclean -> versionclean.
3369 Remove unused external symbols.
3370 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
3371 * window.c (Qwindow_valid_p, decode_valid_window):
3372 Now static, not extern.
3373 * data.c (Qinterval): Remove; unused.
3374 (syms_of_data): Do not define 'interval'.
3375 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
3376 * window.h (decode_valid_window):
3379 * character.c, charset.c, chartab.c: Use bool for booleans.

3389 (char_table_set_range, optimize_sub_char_table)
3390 (map_sub_char_table):
3391 Use bool for boolean.
3392 * character.c (str_to_unibyte): Omit last boolean argument; it was
3393 always 0. All callers changed.
3394 * character.h, charset.h: Adjust to match previous changes.
3395 * character.h (char_printable_p): Remove decl of nonexistent function.
3396 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
3397 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
3398 are all boolean, so make them single-bit bitfields.
3400 * lisp.h (ASET): Remove attempt to detect side effects.
3401 It was meant to be temporary and it often doesn't work,
3402 because when IDX has side effects the behavior of IDX==IDX
3403 is undefined. See Stefan Monnier in
3404 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
3406 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
3408 * lisp.h (functionp): New function (extracted from Ffunctionp).
3409 (FUNCTIONP): Use it.
3410 * eval.c (Ffunctionp): Use it.
3412 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
3414 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
3415 as that's faster and simpler than static storage. Don't bother
3416 with the g_main_context_query overhead if g_main_context_pending
3417 says no events are pending.
3418 (gfds, gfds_size): Remove these static vars.
3419 (xgselect_initialize): Remove; no longer needed.
3420 All uses and decls removed.
3422 * emacs.c (fatal_error_signal_hook): Remove.
3423 All uses removed. This leftover from old code was always 0.
3425 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
3426 * casefiddle.c (casify_object, casify_region):
3427 * casetab.c (set_case_table):
3428 * category.c, category.h (word_boundary_p):
3429 * category.h (CHAR_HAS_CATEGORY):
3430 Use bool for booleans, instead of int.
3432 2012-08-25 Eli Zaretskii <eliz@gnu.org>
3434 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
3436 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
3438 On assertion failure, print backtrace if available.
3439 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
3440 (die) [ENABLE_CHECKING]: Print a backtrace if available.
3441 * Makefile.in (LIB_EXECINFO): New macro.
3444 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
3445 * bytecode.c (exec_byte_code):
3446 * callint.c (check_mark, Fcall_interactively):
3447 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
3448 (getenv_internal, sync_process_alive, call_process_exited):
3449 * lisp.h (USE_SAFE_ALLOCA):
3450 Use bool for booleans, instead of int.
3451 * lisp.h, process.h: Adjust prototypes to match above changes.
3452 * callint.c (Fcall_interactively): Don't assume the mark's
3453 offset fits in 'int'.
3455 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
3457 * buffer.c, buffer.h: Use bool for boolean.
3458 * buffer.c (reset_buffer_local_variables)
3459 (buffer_lisp_local_variables, Fset_buffer_modified_p)

3463 (report_overlay_modification, call_overlay_mod_hooks):
3464 (mmap_enlarge, mmap_set_vars):
3465 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
3466 Use bool for booleans, instead of int.
3467 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
3468 since the 1-or-0 return value is always ignored anyway.
3469 (mmap_initialized_p):
3470 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
3471 * buffer.h, lisp.h: Adjust prototypes to match above changes.
3473 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
3475 * bidi.c: Use bool for boolean.
3476 This is a bit more readable, and makes the text segment of bidi.o
3477 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
3478 Presumably it's faster too.
3479 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
3481 (bidi_cache_find_level_change, bidi_cache_iterator_state)
3482 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
3483 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
3484 (bidi_explicit_dir_char, bidi_level_of_next_char)
3485 (bidi_find_other_level_edge, bidi_move_to_visually_next):
3486 Use bool for booleans, instead of int.
3487 * dispextern.h (bidi_init_it, bidi_paragraph_init)
3488 (bidi_unshelve_cache): Adjust decls to match code.
3490 2012-08-23 Martin Rudalics <rudalics@gmx.at>
3492 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
3495 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
3497 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
3498 * atimer.h: Include <stdbool.h>.
3500 2012-08-22 Dan Nicolaescu <dann@gnu.org>
3502 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
3503 compile time tests instead of run time tests on systems that do
3505 (FRAME_MAC_P): Remove leftover from deleted code.
3506 * frame.c (syms_of_frame): Remove leftover from deleted code.
3508 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
3510 * nsterm.m (insertText:): Don't clear modifiers if code is space.
3512 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
3514 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
3515 Otherwise, the compiler complains about (A?B:C) where B is void
3516 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
3517 (fontset_add): Return void, for FONTSET_ADD.
3519 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3521 * alloc.c: Use bool for booleans.
3522 (gc_in_progress, abort_on_gc)
3523 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
3524 (dont_register_blocks) [GC_MALLOC_CHECK]:
3525 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
3526 (check_string_bytes, make_specified_string, memory_full)
3527 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
3528 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
3529 (mark_stack, valid_pointer_p, make_pure_string)
3530 (Fgarbage_collect, survives_gc_p, gc_sweep):
3531 Use bool for booleans, instead of int.
3532 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
3533 Remove unused local.
3534 * alloc.c (PURE_POINTER_P):
3535 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
3536 * editfns.c (Fformat):
3537 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
3539 * fns.c (sweep_weak_table):
3540 * lisp.h (suppress_checking, push_message, survives_gc_p)
3541 (make_pure_string, gc_in_progress, abort_on_gc):
3542 * lread.c (readchar, read1):
3543 * print.c (Fprin1_to_string):
3544 * xdisp.c (push_message):
3545 Use bool for booleans affected directly or indirectly by
3548 Make recently-introduced setters macros.
3549 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
3550 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
3551 (set_fontset_default, set_fontset_fallback): Rename from their
3552 upper-case counterparts, and make them functions rather than macros.
3553 This is more consistent with the other recently-introduced setters.
3554 These don't need to be inline, since they're local.
3556 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
3558 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
3559 the loop (Bug#12247).
3561 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3563 * lisp.h (vcopy): Use memcpy rather than our own loop.
3564 This fixes a performance regression introduced by the recent
3565 addition of vcopy. This means 'vcopy' will need to be modified
3566 for a copying collector, but that's OK. Also, tighten the
3567 checking in the assertion.
3569 2012-08-21 Eli Zaretskii <eliz@gnu.org>
3571 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
3572 components for RTL text (Bug#11860). Adjust X-OFFSET of each
3573 non-base glyph for the width of the base character, according to
3574 what x_draw_composite_glyph_string_foreground expects.
3575 Generate WADJUST value according to composition_gstring_width's
3576 expectations, to produce correct width of the composed character.
3577 Reverse the sign of the DU offset produced by ScriptPlace.
3579 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3581 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
3583 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
3585 Avoid direct writes to contents member of struct Lisp_Vector.
3586 * lisp.h (vcopy): New function to copy data into vector.
3587 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
3588 * fns.c (Ffillarray): Use ASET.
3589 * keyboard.c (timer_check_2): Use AREF and ASET.
3590 (append_tool_bar_item, Frecent_keys): Use vcopy.
3591 * lread.c (read_vector): Use ASET.
3592 * msdos.c (Frecent_doskeys): Use vcopy.
3593 * xface.c (Finternal_copy_lisp_face): Use vcopy.
3594 (Finternal_merge_in_global_face): Use ASET and vcopy.
3595 * xfont.c (xfont_list_pattern): Likewise.
3597 2012-08-21 Martin Rudalics <rudalics@gmx.at>
3599 * window.c (Fwindow_point): For the selected window always return
3600 the position of its buffer's point.
3601 (Fset_window_point): For the selected window always go in its
3602 buffer to the specified position.
3604 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
3606 Setter macros for fontsets.
3607 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
3608 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
3609 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
3612 2012-08-20 Glenn Morris <rgm@gnu.org>
3614 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
3615 Don't assume that `ln -f' works.
3617 2012-08-20 Eli Zaretskii <eliz@gnu.org>
3619 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
3620 and later about non-assignments with no effect. See discussion at
3621 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
3624 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3626 Inline setter functions for Lisp_Objects slots of struct specbinding.
3627 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
3630 2012-08-20 Martin Rudalics <rudalics@gmx.at>
3632 * window.c (select_window): Always make selected window's buffer
3635 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3637 Use AREF and ASET for docstrings of category tables.
3638 * category.h (CATEGORY_DOCSTRING): Use AREF.
3639 (SET_CATEGORY_DOCSTRING): Use ASET.
3640 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
3642 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3644 Inline setter functions for hash table members.
3645 * lisp.h (set_hash_key, set_hash_value, set_hash_next)

3663 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
3665 Rely on <config.h> + <unistd.h> to declare 'environ',
3666 as gnulib does this if the system doesn't.
3667 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:

4536 2012-08-04 Eli Zaretskii <eliz@gnu.org>
4538 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
4539 * w32.c (init_environment): Change the default values of many
4540 environment variables in dflt_envvars[] to NULL, to avoid pushing
4541 them into environment when they were not already defined.
4542 Remove the code that deletes site-lisp subdirectories from the default
4543 value of EMACSLOADPATH, as it is no longer needed.
4544 (check_windows_init_file): Now external, not static.
4545 Use Vload_path as is, without adding anything, as this function is now
4546 called when Vload_path is already set up.
4548 * w32.h (check_windows_init_file): Add prototype.
4550 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
4551 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
4552 compatibility with Posix platforms.
4553 (main): Move the call to check_windows_init_file to here from
4555 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
4556 any, in the DEFALT argument into the root of the Emacs build or
4557 installation tree, as appropriate.
4559 * callproc.c (init_callproc_1): Call decode_env_path instead of
4560 doing its equivalent by hand.
4561 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
4562 the code that sets Vexec_path run on MS-Windows.
4564 * lread.c (init_lread): Add comments to #ifdef's.
4566 * msdos.c (dos_set_window_size, IT_update_begin)
4567 (IT_frame_up_to_date, IT_set_frame_parameters): Use FVAR and WVAR
4568 instead of direct references.
4570 2012-08-04 Paul Eggert <eggert@cs.ucla.edu>
4572 Export DEFAULT_REHASH_* to GDB.
4573 * lisp.h (DEFAULT_REHASH_THRESHOLD, DEFAULT_REHASH_SIZE):
4574 Now constants, not macros.
4576 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
4578 Remove unnecessary casts involving pointers.
4579 These casts are no longer needed now that we assume C89 or later,
4580 since they involve casting to or from void *.
4581 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
4582 (make_pure_float, make_pure_vector):
4583 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

4592 (x_get_window_property, x_get_window_property_as_lisp_data):
4593 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
4594 Remove unnecessary pointer casts.
4595 * alloc.c (record_xmalloc): New function.
4596 * lisp.h (record_xmalloc): New decl.
4597 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
4598 more like a function. This is because the pointer cast is not
4599 needed. All uses changed.
4600 * print.c (print_string, print_error_message): Avoid length recalc.
4602 Improve fix for macroexp crash with debugging (Bug#12118).
4603 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
4604 ARRAY_MARK_FLAG when checking subscripts, because ASET is
4605 not supposed to be invoked from the garbage collector.
4606 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
4607 (gc_aset): New function, which is like ASET but can be
4608 used in the garbage collector.
4609 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)
4610 (set_hash_index): Use it instead of ASET.

4619 <g_b_init_create_symbolic_link>: New static flags.
4620 (globals_of_w32): Initialize them to zero.
4621 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
4622 (map_w32_filename): Improve commentary. Simplify switch.
4623 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
4624 headers (most versions of MinGW w32api don't).
4625 (get_security_info, create_symbolic_link)
4626 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
4628 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
4629 in the argument file name.
4630 (sys_access): Call unc_volume_file_attributes only if
4631 GetFileAttributes fails with network-related error codes.
4632 (sys_rename): Diagnose renaming of a symlink when the user doesn't
4633 have the required privileges.
4634 (get_file_security_desc_by_name): Rename from
4635 get_file_security_desc.
4636 (stat_worker): New function, with most of the guts of 'stat', and
4637 with addition of handling of symlinks and support for 'lstat'.
4638 If possible, get file's attributes and security information by
4639 handle, not by name. Produce S_IFLNK bit for symlinks, when
4640 called from 'lstat'.
4641 (stat, lstat): New functions, call 'stat_worker'.
4642 (symlink, readlink, careadlinkat): Rewritten to create and resolve
4643 symlinks when the underlying filesystem supports them.
4645 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
4647 Fix macroexp crash on Windows with debugging (Bug#12118).
4648 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
4649 checking subscripts; problem introduced with the recent
4650 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
4651 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
4652 since it's used in non-static inline functions now.
4654 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
4655 Don't assume buffer size fits in 'int'. Remove unused local.
4657 Use C99-style 'extern inline' if available.

4659 * category.h (CATEGORY_INLINE):
4660 * character.h (CHARACTER_INLINE):

4669 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
4670 * alloc.c (LISP_INLINE):
4671 * buffer.c (BUFFER_INLINE):
4672 * category.c (CATEGORY_INLINE):
4673 * character.c (CHARACTER_INLINE):
4674 * charset.c (CHARSET_INLINE):
4675 * composite.c (COMPOSITE_INLINE):
4676 * dispnew.c (DISPEXTERN_INLINE):
4677 * sysdep.c (SYSTIME_INLINE):
4678 Define to EXTERN_INLINE, so that the corresponding functions
4679 are compiled into code.
4680 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
4681 (INLINE_HEADER_END): New macros.
4682 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

4702 hard-coding the path separator.
4704 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
4706 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
4707 This how ASET and AREF are supposed to work, and makes
4708 it easier to think about future improvements. See
4709 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
4710 * charset.h (set_charset_attr): New function.
4711 All lvalue-style uses of CHARSET_DECODER etc. changed to use it.
4712 * lisp.h (ASET): Rewrite so as not to use AREF in an lvalue style.

5091 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
5092 (w32_kbd_patch_key, key_event): Use the codepage returned by
5093 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.

5125 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
5126 enumeration constants, as PURE and HEAP are too general, and clash
5127 with other headers and sources, such as gmalloc.c and the
5128 MS-Windows system headers. All users changed.
5130 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
5132 Revert last save_excursion_save and save_excursion_restore changes.
5133 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

5146 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
5147 arms of an 'if', not using conditional expressions; otherwise GDB
5148 complains about the types in the unevaluated arm when the argument
5149 is an integer literal.
5150 (xgetint): Simplify expression.
5151 * alloc.c (gdb_make_enums_visible): New constant. This ports to
5152 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
5153 Zaretskii in <http://bugs.gnu.org/12036#13>.
5154 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
5155 needed now that we have gdb_make_enums_visible.
5156 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
5157 (enum enum_USE_LSB_TAG):
5158 New enum types, packaging up enums that need to be exported to GDB.

5182 * lisp.h (struct Lisp_Excursion): New data type.
5183 (PVEC_EXCURSION): New pseudovector type.
5184 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
5185 to deal with it. Adjust comments.

5200 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
5201 emacs.c, as this is a more-suitable home. Had this been done earlier
5202 the fix for 12036 would have avoided some of the problems noted in
5203 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
5204 would have been more obvious.
5205 * emacs.c: Do not include <verify.h>; no longer needed.
5206 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
5207 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
5208 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

5214 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
5215 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
5216 not be usable in #if. This simplifies things.
5218 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
5220 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

5225 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
5226 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
5227 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
5228 Adjust to changes in lisp.h and emacs.c, by using
5229 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
5230 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
5231 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
5232 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
5233 instead of gdb_valbits.
5234 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
5235 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
5236 instead of gdb_array_mark_flag.
5237 (xboolvector): Get size from $->size, not $->header.size.
5238 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
5239 (xreload, hook-run, hookpost-run): Remove.
5240 * emacs.c: Include <verify.h>.
5241 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
5242 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
5244 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
5245 (gdb_USE_LSB_TAG): New enum constants.
5246 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
5247 Also define these as enum constants, so they're visible to GDB.
5248 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
5249 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
5250 as constants, so they're visible to GDB.

5253 Now enum constants, not macros, so they're visible to GDB.
5254 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
5255 more convenient now. All uses changed.
5256 (VALMASK) [USE_LSB_TAG]: Also define in this case.
5257 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
5259 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

5264 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
5266 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
5267 add argument, tune behavior, and adjust all callers.
5269 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
5271 Use typedef for EMACS_INT, EMACS_UINT.
5272 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
5273 than macros. This simplifies debugging in the usual case, since
5274 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
5275 and it allows expressions involving EMACS_INT casts.
5276 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
5278 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

5288 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
5290 Adjust buffer text indirection counters at the end of Fkill_buffer.
5291 * buffer.c (Fkill_buffer): Adjust indirection counters when the
5292 buffer is definitely dead. This should really fix an issue reported
5293 by Christoph Scholtes again. (Bug#12007).
5294 (init_buffer_once): Initialize indirection counters of
5295 buffer_defaults and buffer_local_symbols (for sanity and safety).
5297 2012-07-24 Eli Zaretskii <eliz@gnu.org>
5299 * xdisp.c (init_iterator): Don't compute dimensions of truncation
5300 and continuation glyphs on tooltip frames, leave them at zero.

5303 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
5305 Simplify copy_overlay.
5306 * buffer.c (copy_overlay): Simplify. Use build_marker.

5317 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
5319 Cleanup miscellaneous objects allocation and initialization.
5320 * alloc.c (allocate_misc): Change to static. Add argument to

5326 (build_overlay): Add prototype.
5328 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
5330 Swap buffer text indirection counters in Fbuffer_swap_text.
5331 * buffer.c (Fbuffer_swap_text): Swap indirections too.
5332 This avoids crash reported by Christoph Scholtes at
5333 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
5335 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
5337 * nsmenu.m (Popdown_data): New struct.
5338 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
5340 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
5341 (initWithContentRect): Make imgView and contentView non-static
5342 and autorelease them. Also autorelease img and matrix (Bug#12005).
5343 (dealloc): Remove (Bug#12005).
5345 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
5347 Adjust consing_since_gc when objects are explicitly freed.
5348 * alloc.c (GC_DEFAULT_THRESHOLD): New macro.
5349 (Fgarbage_collect): Use it. Change minimum to 1/10 of default.

5356 (live_buffer, set_marker_internal): New function.
5357 (Fset_marker, set_marker_restricted): Use set_marker_internal.
5358 (set_marker_both, set_marker_restricted_both): Use live_buffer.
5360 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
5362 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
5363 as it's limited by the amount of memory, not by INT_MAX.
5365 2012-07-21 Eli Zaretskii <eliz@gnu.org>
5367 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
5368 in special-event-map. See the discussion at

6091 * s/aix4-2.h (unix): Remove; no longer needed.
6093 EMACS_TIME simplification (Bug#11875).
6094 This replaces macros (which typically do not work in GDB)
6095 with functions, typedefs and enums, making the code easier to debug.
6096 The functional style also makes code easier to read and maintain.
6097 * systime.h: Include <sys/time.h> on all hosts, not just if
6098 WINDOWSNT, since 'struct timeval' is needed in general.

6111 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
6112 not functions. All uses rewritten to use the following, respectively:
6113 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
6114 (add_emacs_time, sub_emacs_time): New functions.
6115 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

6138 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
6139 Prefer snprintf to strncpy.
6140 * nsterm.m (ns_term_init):
6141 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
6142 * nsterm.m (ns_term_init):
6143 Avoid the need for strncpy, by using build_string or
6144 make_unibyte_string directly. Use dtoastr, not snprintf.
6145 * process.c (Fmake_network_process): Diagnose service names that
6146 are too long, rather than silently truncating them or creating
6147 non-null-terminated names.
6148 (Fnetwork_interface_info): Likewise, for interface names.
6149 * sysdep.c (system_process_attributes) [GNU_LINUX]:
6150 Prefer sprintf to strncat.

6157 Clarify fallback case.
6159 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>

6164 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
6165 where argument type is known to be a Lisp_Cons.

6220 O_RDONLY already includes it).
6222 Stop ns builds setting the EMACSLOADPATH environment variable.
6223 * nsterm.m (ns_load_path): Rename from ns_init_paths.
6224 Now it does not set EMACSLOADPATH, just returns the load-path string.

6226 * lread.c [HAVE_NS]: Include nsterm.h.
6227 (init_lread) [HAVE_NS]: Use ns_load_path.

6237 (ns_init_paths): Do not set EMACSPATH.

6295 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
6297 Move marker debugging code under MARKER_DEBUG.
6298 * marker.c (MARKER_DEBUG): Move marker debugging code under
6299 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
6300 for bootstrap with --enable-checking (~3x slowdown reported
6301 by Juanma Barranquero <lekktu@gmail.com>).
6302 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
6304 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
6306 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
6307 See <http://bugs.gnu.org/11825#29>.
6309 2012-07-08 Eli Zaretskii <eliz@gnu.org>
6311 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
6312 has no font, use the frame's font. (Bug#11813)
6313 (display_line): Add commentary about displaying truncation glyphs
6315 (produce_special_glyphs): Move here from term.c.
6317 * term.c (produce_special_glyphs): Move to xdisp.c.
6319 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
6322 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
6324 * xdisp.c (display_line): Avoid warning about implicit declaration
6327 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
6329 * lisp.h: Remove empty conditional.
6331 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
6333 * lread.c (load_path_check): Now static.
6335 Fix some minor --with-ns problems found by static checking.
6336 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
6337 (x_set_font) [!HAVE_X_WINDOWS]:
6338 * image.c (xpm_load_image) [HAVE_NS]:
6339 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
6340 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
6341 Remove unused local.
6342 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
6343 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
6344 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
6345 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
6346 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
6347 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
6348 Fix pointer signedness problem.
6349 * xfaces.c (FRAME_X_FONT_TABLE):
6350 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
6352 2012-07-07 Glenn Morris <rgm@gnu.org>
6354 * lread.c (load_path_check): New function, split from init_lread.
6355 (init_lread): Reorganize. Motivation:
6356 If EMACSLOADPATH is set, check/warn about that rather than the
6357 defaults, which we are not going to use. Hence we can remove
6358 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
6359 Don't warn if site-lisp directories are missing.
6360 If not installed, start from a blank load-path, since
6361 PATH_LOADSEARCH refers to the eventual installation directories.
6363 2012-07-07 Eli Zaretskii <eliz@gnu.org>
6365 Support truncation and continuation glyphs on GUI frames, when
6366 fringes are disabled. (Bug#11832)
6367 * xdisp.c (init_iterator): Get dimensions of truncation and
6368 continuation glyphs even if on GUI frames.
6369 Adjust it->last_visible_x on GUI frames when the left or right fringes,
6370 or both, are absent.
6371 (start_display, move_it_in_display_line_to): Handle the case of a
6372 GUI frame without a fringe to display continuation or truncation
6374 (insert_left_trunc_glyphs): Support GUI frames: make sure
6375 truncation glyphs overwrite enough glyphs from the current line to
6376 have sufficient space in pixels.
6377 (display_line): Support truncation and continuation glyphs on GUI
6378 frames. If some spare pixels are left on the line after inserting
6379 the truncation glyphs, fill that space with a stretch glyph of a
6380 suitably computed width.
6382 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
6383 produce_glyphs, to support GUI sessions.
6385 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
6387 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
6389 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
6391 Do not require float-time's arg to fit in time_t (Bug#11825).
6392 This works better on hosts where time_t is unsigned, and where
6393 float-time is applied to the (negative) difference between two times.
6394 * editfns.c (decode_time_components): Last arg is now double *,
6395 not int *, and means to store all the result as a double, without
6396 worrying about whether the seconds part fits in time_t.
6397 All callers changed.
6398 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
6399 All callers changed.
6400 (Ffloat_time): Do not fail merely because the specified time falls
6401 outside of time_t range.
6403 2012-07-07 Glenn Morris <rgm@gnu.org>
6405 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
6406 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
6407 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
6409 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
6411 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
6412 Update dependencies.
6414 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
6416 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6418 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
6419 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
6420 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
6421 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
6422 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
6423 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
6425 * xfont.c (compare_font_names): Redo to omit the need for casts.
6427 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
6429 * xfns.c (Fx_change_window_property): Doc fix.
6430 * w32fns.c (Fx_change_window_property): Doc fix.
6432 * w32fns.c (Fx_window_property): Accept the same arguments as the
6433 X Windows version. Doc fix.
6434 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
6436 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
6437 Eli Zaretskii <eliz@gnu.org>
6439 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
6440 Windows-specific code from nt/config.nt moved here.
6441 Obsolete settings removed.
6443 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6445 * process.c: Avoid unnecessary calls to gettime.
6446 (wait_reading_process_output): Don't get the time of day
6447 when gobbling data immediately and not waiting, as there's no need
6448 for it in that case. This removes a FIXME.
6450 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
6452 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
6453 is defined (Bug#11768).
6455 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6457 Fix marker debugging code.
6458 * marker.c (byte_char_debug_check): Do not perform the check
6459 if buffer is not multibyte.
6460 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
6461 Call byte_char_debug_check with correct arguments.
6463 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6465 Compile marker debugging code only if ENABLE_CHECKING is defined.
6466 * marker.c (byte_char_debug_check, count_markers):
6467 Use only if ENABLE_CHECKING is defined.
6468 (byte_debug_flag): Remove.
6469 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
6470 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
6472 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6474 Avoid code repetition in marker-related functions.
6475 * marker.c (attach_marker): New function.
6476 (Fset_marker, set_marker_restricted, set_marker_both)
6477 (set_marker_restricted_both): Use it.
6478 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
6479 Consistently rename charno to charpos.
6480 (marker_position): Add eassert.
6481 (marker_byte_position): Convert to eassert.
6483 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6485 Simplify list operations in unchain_overlay and unchain_marker.
6486 * buffer.c (unchain_overlay): Simplify. Add comment.
6487 * marker.c (unchain_marker): Simplify. Fix comments.
6489 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6491 Introduce fast path for the widely used marker operation.
6492 * alloc.c (build_marker): New function.
6493 * lisp.h (build_marker): New prototype.
6494 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
6495 * composite.c (autocmp_chars): Likewise.
6496 * editfns.c (buildmark): Remove.
6497 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
6498 (save_restriction_save): Use build_marker.
6499 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
6500 * window.c (save_window_save): Likewise.
6502 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6504 Do not use Fdelete_overlay in delete_all_overlays
6505 to avoid redundant calls to unchain_overlay.
6506 * buffer.c (drop_overlay): New function.
6507 (delete_all_overlays, Fdelete_overlay): Use it.
6508 * minibuf.c (get_minibuffer): Fix comment.
6510 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6512 Port to OpenBSD 5.1 amd64.
6513 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
6514 This is needed for OpenBSD, and should be harmless on all BSD systems.
6515 Also, include <sys/sysctl.h>, as it should be available on all
6516 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
6517 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
6518 use p_pid member, not kp_proc.pid.
6520 2012-07-06 Glenn Morris <rgm@gnu.org>
6522 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
6524 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
6526 More xmalloc and related cleanup.
6527 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
6528 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
6529 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:

6531 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:
6532 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:
6533 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
6534 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
6535 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
6537 Omit needless casts involving void * pointers and allocation.
6538 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
6539 as the former is more robust if P's type is changed.
6540 Prefer xzalloc to xmalloc + memset 0.
6541 Simplify malloc-or-realloc to realloc.
6542 Don't worry about xmalloc returning a null pointer.
6543 Prefer xstrdup to xmalloc + strcpy.
6544 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
6546 * keyboard.c (apply_modifiers_uncached): Prefer local array to
6547 alloca of a constant.
6549 2012-07-05 Eli Zaretskii <eliz@gnu.org>
6551 * xdisp.c (display_line): Fix horizontal pixel coordinates when
6552 hscroll is larger than the line width. Fixes long and futile
6553 looping inside extend_face_to_end_of_line (on a TTY) producing
6554 glyphs that are not needed and thrown away.
6556 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
6558 * marker.c (set_marker_restricted_both): Simplify by using
6561 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
6563 * editfns.c (region_limit): Simplify by using clip_to_bounds.
6565 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
6567 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
6568 not defined (Bug#11768).
6569 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
6570 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
6571 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
6572 followed by gtk_box_set_homogeneous (Bug#11768).
6573 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
6574 (update_theme_scrollbar_width, xg_create_scroll_bar):
6575 Use gtk_scrollbar_new (Bug#11768).
6576 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
6577 (is_box_type): New function (Bug#11768).
6578 (xg_tool_item_stale_p): Call is_box_type.
6579 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
6580 with default display (Bug#11768).
6582 2012-07-05 Eli Zaretskii <eliz@gnu.org>
6584 * xdisp.c (window_hscroll_limited): New function.
6585 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
6586 coordinates when window's hscroll is set to insanely large
6589 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
6591 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
6592 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
6594 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
6597 * lisp.h (xzalloc): New prototype. Omit needless casts.
6598 * alloc.c (xzalloc): New function. Omit needless casts.
6599 * charset.c: Omit needless casts. Convert all calls to
6600 xmalloc with following memset to xzalloc.
6601 * dispnew.c: Likewise.
6602 * fringe.c: Likewise.
6603 * image.c: Likewise.

6650 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
6652 * fileio.c (time_error_value): Check the right error number.
6653 Problem reported by Troels Nielsen in
6654 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
6656 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6658 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
6659 This should be fixed in a better way; see Eli Zaretskii in
6660 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
6661 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
6663 * fileio.c (time_error_value): Rename from special_mtime.
6664 The old name's problems were noted by Eli Zaretskii in
6665 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
6667 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
6668 This variable's comment says Emacs needs at least one GDB-visible
6669 symbol of type enum pvec_type, to work around GDB problems.
6670 The symbol's value doesn't matter.
6672 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
6673 that causes compilation to fail on pre-C99 compilers.
6675 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
6677 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
6678 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
6680 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6682 * buffer.c (init_buffer_once): Fix initialization of
6683 headers for buffer_defaults and buffer_local_symbols.
6684 Reported by Juanma Barranquero <lekktu@gmail.com>.
6686 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
6688 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
6689 * lisp.h (enum pvec_type): Use fewer bits.
6690 (PSEUDOVECTOR_SIZE_BITS): New constant.
6691 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
6692 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
6693 change in pvec_type.
6694 (PSEUDOVECTOR_TYPEP): New macro.
6695 (TYPED_PSEUDOVECTORP): Use it.
6696 * fns.c (internal_equal): Adapt code to extract pvectype.
6697 * emacs.c (gdb_pvec_type): Update type.
6698 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
6699 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
6700 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
6701 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
6702 (sweep_vectors): Use it. Use local var `total_bytes' instead of
6703 abusing vector->header.next.nbytes.
6704 (live_vector_p): Use PVEC_TYPE.
6705 (mark_object): Adapt code to extract pvectype. Use switch.
6707 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6709 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
6710 Tighten new eassert a bit.
6712 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6714 Fix compilation with --enable-gcc-warnings and -O1
6716 * doprnt.c (doprnt): Change type of tem to int, initialize
6717 to avoid compiler warning. Add eassert.
6718 * search.c (simple_search): Initialize match_byte to avoid
6719 compiler warning. Add eassert.
6721 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6723 Avoid weird behavior with large horizontal scrolls.
6724 Without this change, for example, large hscroll values would
6725 mess up Emacs's display on Fedora 15 x86, presumably due to
6726 overflows in int calculations in the display code.
6727 Also, if buffers had long lines, Emacs would freeze.
6728 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
6729 (set_window_hscroll): New function, containing the old guts of
6730 Fset_window_hscroll. Return the clipped value.
6731 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
6732 This avoids the need to check against PTRDIFF_MAX.
6734 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
6736 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6738 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
6740 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6742 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
6743 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
6744 since GCC 4.4.6 issues a bogus warning for them.
6746 Fix bugs in file timestamp newness comparisons.
6747 * fileio.c (Ffile_newer_than_file_p):
6748 * lread.c (Fload): Use full timestamp resolution of files,
6749 not just the 1-second resolution, so that files that are only
6750 slightly newer still count as newer.
6751 * fileio.c (Ffile_newer_than_file_p): Don't assume file
6752 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
6754 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
6756 * fileio.c: Improve handling of file time marker. (Bug#11852)
6757 (special_mtime): New function.
6758 (Finsert_file_contents, Fverify_visited_file_modtime):
6759 Use it to set special mtime values consistently.
6761 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
6763 * fileio.c (Finsert_file_contents): Properly handle st_mtime
6764 marker for non-existing file. (Bug#11852)
6766 2012-07-03 Glenn Morris <rgm@gnu.org>
6768 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
6769 and did not make it into globals.h).
6771 2012-07-03 Tom Tromey <tromey@redhat.com>
6773 * window.c (Fset_window_margins, Fset_window_fringes)

6818 values which aren't power of 2.
6819 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
6820 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
6823 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
6825 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.

6831 * alloc.c (allocate_vector_block): Remove redundant
6832 calls to mallopt if DOUG_LEA_MALLOC is defined.
6833 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
6834 avoid calls to mallopt if zero_vector is returned.
6836 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6838 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
6839 is enabled, avoid dereferencing NULL current_sblock if
6842 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6844 Cleanup basic buffer management.
6845 * buffer.h (struct buffer): Change layout to use generic vector
6846 marking code. Fix some comments. Change type of 'clip_changed'
6847 to bitfield. Remove unused #ifndef old.
6848 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
6849 (GET_OVERLAYS_AT): Fix indentation.
6850 (for_each_per_buffer_object_at): New macro.
6851 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

6854 * alloc.c (allocate_buffer): Adjust to match new layout of
6855 struct buffer. Fix comment.
6856 (mark_overlay): New function.
6857 (mark_buffer): Use it. Use mark_vectorlike to mark normal
6858 Lisp area of struct buffer.
6859 (mark_object): Use it. Adjust marking of misc objects
6860 and related comments.
6862 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
6864 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
6865 wrapper that is not needed because the wrapped code is a no-op (zero
6866 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
6867 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
6869 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
6871 * alloc.c (mark_buffer): Simplify. Remove prototype.
6872 (mark_object): Add comment. Reorganize marking of vector-like
6873 objects. Use CHECK_LIVE for all vector-like objects except buffers
6874 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
6875 Avoid redundant calls to mark_vectorlike for bool vectors.
6877 2012-06-30 Glenn Morris <rgm@gnu.org>
6879 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
6881 * epaths.in (PATH_SITELOADSEARCH): New.
6882 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
6883 This is rather than relying on --enable-locallisppath elements
6884 having "site-lisp" in their names. (Bug#10208#25, 11658)
6886 2012-06-30 Eli Zaretskii <eliz@gnu.org>
6888 * w32proc.c (sys_select): Accept and ignore one more argument.
6890 * w32.c (emacs_gnutls_pull): Call select with one more argument.
6892 * sysselect.h [DOS_NT]: Don't include sys/select.h.
6893 (pselect) [!MS_DOS]: Redirect to sys_select.
6895 * sysdep.c: Don't include dos.h and dosfns.h.
6897 * process.c (sys_select):
6898 * msdos.c (sys_select): Accept one more argument and ignore it.
6900 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
6901 adapt data types and code to that.
6904 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
6905 which clashes with the gnulib function of the same name.
6907 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
6909 * font.c (font_style_to_value, font_style_symbolic)
6910 (font_prop_validate_style): Add type checks for values in
6913 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
6915 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
6918 2012-06-29 Eli Zaretskii <eliz@gnu.org>
6920 * xdisp.c (try_window_id): Undo last change.
6922 * w32.c (getwd): Adjust commentary about startup_dir.
6923 (init_environment): Always call sys_access, even in non-MSVC
6924 builds. Don't chdir to the directory of the Emacs executable.
6925 This undoes code from 1997 which was justified by the need to
6926 "avoid conflicts when removing and renaming directories". But its
6927 downside was that every relative file name was being interpreted
6928 relative to the directory of the Emacs executable, which can never
6929 be TRT. In particular, it broke sys_access when called with
6930 relative file names.
6931 (sys_access): Map GetLastError to errno.
6933 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
6935 * window.h (struct window): Change type of 'fringes_outside_margins'

6939 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
6942 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>

6945 Add QUIT to make the loop interruptible.
6947 2012-06-29 Glenn Morris <rgm@gnu.org>
6949 * charset.c (init_charset): Make lack of etc/charsets fatal.
6951 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
6953 * editfns.c (region_limit): Fix type mismatch.
6955 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
6957 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
6958 undefined. Convert from xassert to eassert.
6959 * nsmenu.m: Convert from xassert to eassert.
6960 * nsterm.m: Likewise.
6962 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>

6966 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
6968 Avoid integer overflow on scroll-left and scroll-right.
6969 * window.c (HSCROLL_MAX): New macro.
6970 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer

6975 * window.h (struct window): Change type of 'hscroll',
6976 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
6977 'last_modified' and 'last_overlay_modified' to EMACS_INT.
6978 Adjust users accordingly.
6979 * xdisp.c (try_cursor_movement): Replace type check with eassert.
6980 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
6981 from EMACS_INT to ptrdiff_t.

6988 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
6990 * window.h (struct window): Change type of 'use_time' and

7057 * alloc.c (allocate_string): Omit intervals initialization.
7058 * alloc.c (make_uninit_multibyte_string): Initialize intervals

7117 a better opportunity to optimize away calls to strlen when the
7118 function is called with compile-time constant argument.
7119 * image.c (imagemagick_error): Convert to build_string.
7120 * w32proc.c (sys_spawnve): Likewise.

7123 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
7125 Use sprintf return value instead of invoking strlen on result.
7126 In the old days this wasn't portable, since some sprintf
7127 implementations returned char *. But they died out years ago and
7128 Emacs already assumes sprintf returns int.
7129 Similarly for float_to_string.
7130 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
7131 * ccl.c (ccl_driver):

7137 * xfns.c (syms_of_xfns):
7138 Use sprintf or float_to_string result to avoid need to call strlen.
7139 * data.c (Fnumber_to_string):
7140 Use make_unibyte_string, since the string must be ASCII.
7141 * lisp.h, print.c (float_to_string): Now returns int length.
7142 * term.c (produce_glyphless_glyph):
7143 Use sprintf result rather than recomputing it.
7145 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
7146 * Makefile.in (ALL_CFLAGS):

7178 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

7181 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
7183 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
7184 instead of truncating it to 63 (admittedly a generous limit).
7186 * process.c: Fix spelling and caps in comments.
7188 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
7190 * emacs.c (setpgrp): Remove definition, unused.

7237 Remove unnecessary forward decls.

7244 * keyboard.c (kbd_buffer_get_event):

7280 language ID in the event parameters.
7282 * w32term.c (w32_read_socket): Put the new keyboard codepage into

7312 Don't assume EMACS_TIME and struct timeval are the same type.
7314 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
7316 Support higher-resolution time stamps (Bug#9000).
7317 The time stamps are only nanosecond-resolution at the C level,
7318 since that's the best that any real-world system supports now.
7319 But they are picosecond-resolution at the Lisp level, as that's
7320 easy, and leaves room for future OS improvements.
7322 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
7325 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
7326 Don't get current time unless it's needed.
7328 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
7329 now provides it if it's absent.
7330 (start_atimer): Port to higher-res time stamps.
7331 Check for time stamp overflow. Don't get current time more
7332 often than is needed.
7334 * buffer.h (struct buffer): Buffer modtime now has high resolution.
7335 Include systime.h, not time.h.
7336 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
7338 * dired.c: Include stat-time.h.
7339 (Ffile-attributes): File times now have higher resolution.

7342 (struct image): Timestamp now has higher resolution.
7344 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
7345 has at least microseconds now. All uses removed.
7346 (update_frame, update_single_window, update_window, update_frame_1)
7347 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
7348 (duration_to_sec_usec): Remove; no longer needed.

7357 (make_time): Now static.
7358 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
7359 Report an error if the time is invalid, rather than having the caller
7362 * fileio.c: Include <stat-time.h>
7363 (Fcopy_file): Copy higher-resolution time stamps.
7364 Prefer to set the time stamp via a file descriptor if that works.

7366 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
7367 (Fvisited_file_modtime, Fset_visited_file_modtime):
7368 Support higher-resolution time stamps.
7370 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
7372 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
7374 * image.c (prepare_image_for_display, clear_image_cache)
7375 (lookup_image): Port to higer-resolution time stamps.
7377 * keyboard.c (start_polling, bind_polling_period):
7378 Check for time stamp overflow.
7379 (read_char, kbd_buffer_get_event, timer_start_idle)
7380 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
7381 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
7382 Port to higher-resolution time stamps. Do not assume time_t is signed.
7383 (decode_timer): New function. Timers are now vectors of length 9,
7384 not 8, to accommodate the picosecond component.
7385 (timer_check_2): Use it.
7387 * nsterm.m (select_timeout, timeval_subtract): Remove.
7388 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
7389 as they're a bit more accurate and handle overflow better.
7390 (ns_select): Change prototype to be compatible with pselect.
7391 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
7392 * nsterm.h (ns_select): Adjust prototype.
7394 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
7395 us-resolution time stamps.
7396 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
7398 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
7400 * lisp.h (time_overflow): New decl.
7401 (wait_reading_process_output): First arg is now intmax_t, not int,
7402 to accommodate larger waits.
7404 * process.h (struct Lisp_Process.read_output_delay):
7405 Now counts nanoseconds, not microseconds.
7406 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
7408 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
7409 (wait_reading_process_output):
7410 Port to ns-resolution time stamps.
7411 (Faccept_process_output, wait_reading_process_output):
7412 Check for time stamp overflow. Do not assume time_t is signed.
7413 (select_wrapper): Remove; we now use pselect.
7414 (Fprocess_attributes): Now generates ns-resolution time stamps.
7416 * sysdep.c: Include utimens.h. Don't include utime.h
7417 or worry about struct utimbuf; gnulib does that for us now.
7418 (gettimeofday): Remove; gnulib provides a substitute.
7419 (make_timeval): New function.
7420 (set_file_times): Now sets ns-resolution time stamps.
7421 New arg FD; all uses changed.
7422 (time_from_jiffies, ltime_from_jiffies, get_up_time)
7423 (system_process_attributes):
7424 Now returns ns-resolution time stamp. All uses changed.
7425 Check for time stamp overflow.
7427 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
7428 provides a substitute now.
7430 * systime.h: Include timespec.h rather than sys/time.h and time.h,
7431 since it guarantees struct timespec.
7432 (EMACS_TIME): Now struct timespec, so that we can support
7433 ns-resolution time stamps.
7434 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
7435 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
7436 (EMACS_USECS): Remove.
7437 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
7438 so multiply the arg by 1000 before storing it.
7439 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
7441 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
7442 Port to ns-resolution time stamps.
7443 (EMACS_TIME_NEG_P): Remove; replaced by....
7444 (EMACS_TIME_SIGN): New macro.

7446 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
7447 (set_file_times, make_time, lisp_time_argument): Adjust signature.
7448 (make_timeval, make_lisp_time, decode_time_components): New decls.
7449 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
7450 that it mishandled time_t overflow. You can't compare by subtracting!
7451 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
7452 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
7454 * term.c: Include <sys/time.h>.

7460 (Fprimitive_undo): Use them when restoring time stamps.
7462 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
7463 (w32_get_internal_run_time):
7464 Port to higher-resolution Emacs time stamps.
7465 (ltime): Now accepts single 64-bit integer, as that's more convenient
7468 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
7470 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
7471 for compatibility with pselect. Support ns-resolution time stamps.
7473 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
7475 * xselect.c (wait_for_property_change, x_get_foreign_selection):
7476 Check for time stamp overflow, and support ns-resolution time stamps.
7478 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
7479 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
7480 (timeval_subtract): Remove; no longer needed.
7481 (XTflash, XTring_bell, x_wait_for_event):
7482 Port to ns-resolution time stamps. Don't assume time_t is signed.
7484 2012-06-22 Chong Yidong <cyd@gnu.org>

7488 2012-06-22 Eli Zaretskii <eliz@gnu.org>
7490 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
7491 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
7492 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
7493 staticidx goes up to 1597 out of 1600 = 0x640.)
7495 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
7497 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
7498 Otherwise, the umask might be mistakenly 0 while handling input signals.

7532 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
7533 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
7534 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

7543 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
7544 gets killed during executing of this function (Bug#11665).
7545 Try to always return Qt when the buffer has been actually killed.
7546 (Vkill_buffer_query_functions): In doc-string say that functions
7547 run by this hook should not change the current buffer.
7549 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
7551 Fix recently-introduced process.c problems found by static checking.

7569 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
7571 * lisp.h (eassert): Assume C89 or later.
7572 This removes the need for CHECK.
7573 (CHECK): Remove. Its comments about always evaluating its
7574 argument were confusing, as 'eassert' typically does not evaluate
7577 * coding.c (produce_chars): Use ptrdiff_t, not int.
7579 * xterm.c (x_draw_underwave): Check for integer overflow.
7580 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

7732 * frame.c (delete_frame): Remove outdated comment.
7733 * w32fns.c (Fw32_register_hot_key): Use XLI instead of checking
7734 USE_LISP_UNION_TYPE.

7736 (Fw32_toggle_lock_key): Likewise.
7737 * w32menu.c (add_menu_item): Likewise.
7738 (w32_menu_display_help): Use XIL instead of checking

7749 * s/gnu.h (POSIX_SIGNALS): Remove (not used since 2010-05-04).
7751 2012-06-13 Paul Eggert <eggert@cs.ucla.edu>
7753 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
7754 * alloc.c (make_number) [!defined make_number]:
7755 Remove, as lisp.h always defines this now.
7756 (mark_maybe_pointer): Simplify since USE_LSB_TAG is always defined now.
7757 (roundup_size): Verify that it is a power of 2.
7758 * data.c (Fmake_variable_buffer_local, Fmake_local_variable):
7759 * ftfont.c (ftfont_driver): Use LISP_INITIALLY_ZERO.
7760 * lisp.h (USE_LSB_TAG): Allow the builder to compile with
7761 -DUSE_LSB_TAG=0, to override the automatically-selected default.
7762 USE_LSB_TAG now is always defined to be either 0 or 1.
7764 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
7765 code works fine either way, and efficiency is not a concern here,
7766 as the union type is for debugging, not for production.
7767 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
7768 Use an inline function on all platforms when using the union type,
7769 since this is simpler and 'static inline' can be used portably
7771 (LISP_INITIALLY_ZERO): New macro.
7772 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
7773 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

7800 * s/gnu-kfreebsd.h, s/gnu-linux.h, s/gnu.h, s/hpux10-20.h:
7801 * s/irix6-5.h, s/ms-w32.h, s/msdos.h, s/template.h:
7802 * s/usg5-4-common.h: Move SYSTEM_TYPE to configure.

7841 * dbusbind.c (XD_BASIC_DBUS_TYPE): Use dbus_type_is_valid and
7842 dbus_type_is_basic if available.
7843 (xd_extract_signed, xd_extract_unsigned): Rename from
7844 extract_signed and extract_unsigned, respectively. Adapt callers.
7846 2012-06-09 Chong Yidong <cyd@gnu.org>
7848 * xfaces.c (face_for_overlay_string): Handle face remapping (Bug#2066).

7853 2012-06-08 Paul Eggert <eggert@cs.ucla.edu>
7855 * xdisp.c (vmessage): Treat frame message as multibyte.
7856 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
7857 would generate the diagnostic "Making \302\247 buffer-local while
7860 2012-06-08 Eli Zaretskii <eliz@gnu.org>
7862 * dispnew.c (showing_window_margins_p): Undo last change, which

7875 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
7876 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
7878 2012-06-08 Eli Zaretskii <eliz@gnu.org>
7880 * alloc.c (allocate_vectorlike): Fix last change.
7882 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
7884 Block-based vector allocation of small vectors.
7885 * lisp.h (struct vectorlike_header): New field `nbytes',
7886 adjust comment accordingly.
7887 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
7888 to denote vector blocks. Adjust users (live_vector_p,
7889 mark_maybe_pointer, valid_lisp_object_p) accordingly.

7909 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
7911 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
7913 * doprnt.c (doprnt): Truncate multibyte char correctly.
7914 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
7915 would mishandle a string argument "Xc" if X was a multibyte
7916 character of length 2: it would truncate after X's first byte
7917 rather than including all of X.
7919 2012-06-06 Chong Yidong <cyd@gnu.org>
7921 * buffer.c (word_wrap): Doc fix.

7970 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
7971 Convert pctcpu and pctmem to Lisp float properly.
7972 Let the compiler fold better, as 100.0/0x8000 is exact.
7974 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
7976 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
7979 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
7981 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
7983 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
7985 For a 'struct window', replace some Lisp_Object fields to
7986 bitfields where appropriate, remove unused fields.
7987 * window.h (struct window): Remove unused 'last_mark_x' and
7988 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
7989 change its type from Lisp_Object to bitfield.
7990 Change type of 'force_start', 'optional_new_start',
7991 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
7992 fields from Lisp_Object to bitfield. Adjust users accordingly.
7994 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
7996 Pacify gcc -Wdouble-precision when using Xaw.
7997 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
7998 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
7999 Use 'float' consistently, rather than 'float' in most places
8000 and 'double' in a couple of places.
8002 2012-05-31 Eli Zaretskii <eliz@gnu.org>
8004 * xdisp.c (handle_stop): Detect whether we have overlay strings
8005 loaded by testing it->current.overlay_string_index to be
8006 non-negative, instead of checking whether n_overlay_strings is
8007 positive. (Bug#11587)
8009 2012-05-31 Chong Yidong <cyd@gnu.org>
8011 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
8013 * doc.c (Fsubstitute_command_keys): Doc fix.
8015 2012-05-31 Eli Zaretskii <eliz@gnu.org>
8017 * search.c (search_buffer): Remove calls to
8018 r_alloc_inhibit_buffer_relocation, as it is now called by
8019 maybe_unify_char, which was the cause of relocation of buffer text
8022 2012-05-31 Eli Zaretskii <eliz@gnu.org>
8024 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
8025 for the duration of call to load_charset, to avoid problems with
8026 callers of maybe_unify_char that access buffer text through C
8029 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
8030 decrement the inhibition flag, instead of just setting or
8033 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
8035 Remove obsolete '#define static' cruft.
8036 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
8037 This #undef was "temporary" in 2000; it is no longer needed
8038 now that '#define static' has gone away.
8039 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
8040 (gray_bitmap_bits): Remove; no longer needed.
8041 All uses replaced with definiens.
8042 * xterm.c: Include "bitmaps/gray.xbm".
8044 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
8046 Clean up __executable_start, monstartup when --enable-profiling.
8047 The following changes affect the code only when profiling.
8048 * dispnew.c (__executable_start): Rename from safe_bcopy.
8049 Define only on platforms that need it.
8050 * emacs.c: Include <sys/gmon.h> when profiling.
8051 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.

8053 (safe_bcopy): Remove decl; no longer has that name.
8054 (main): Coalesce #if into single bit of code, for simplicity.

8082 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
8084 Do not create empty overlays with the evaporate property (Bug#9642).
8085 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
8086 Bug#9642, but explicitly check that the buffer the overlay would
8087 be moved to is live and rearrange lines to make sure that errors
8088 will not put the overlay in an inconsistent state.
8089 (Fdelete_overlay): Cosmetics.
8091 2012-05-28 Eli Zaretskii <eliz@gnu.org>
8093 * w32term.c (my_bring_window_to_top): New function.
8094 (x_raise_frame): Use handle returned by DeferWindowPos, which

8105 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
8107 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
8108 This avoids undefined behavior that might cause the eassert
8109 to not catch an out-of-range value.
8111 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
8113 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

8125 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
8127 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
8128 Only r_alloc_inhibit_buffer_relocation needed to be added;
8129 the others were already declared.
8131 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
8132 before checking whether it's out of range. Put the check inside
8134 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
8136 2012-05-27 Ken Brown <kbrown@cornell.edu>
8138 * callproc.c (Fcall_process): Restore a line that was accidentally
8139 commented out in the 2011-02-13 change (bug#11547).

8143 * lisp.h [REL_ALLOC]: Add prototypes for external functions
8144 defined on ralloc.c.
8146 * buffer.c [REL_ALLOC]: Remove prototypes of
8147 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
8148 they are now on lisp.h.
8150 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
8152 * search.c (search_buffer): Use it to inhibit relocation of buffer
8153 text while re_search_2 is doing its job, because re_search_2 is
8154 passed C pointers to buffer text. (Bug#11519)
8156 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
8159 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
8160 state after an additional call to move_it_in_display_line_to, keep
8161 the values of it->max_ascent and it->max_descent found for the

8164 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
8167 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
8169 Fix coding-related core dumps with gcc -ftrapv.
8170 The code was computing A - B, where A and B are pointers, and B is
8171 random garbage. This can lead to core dumps on platforms that
8172 have special pointer registers, and it also leads to core dumps on
8173 x86-64 when compiled with gcc -ftrapv. The fix is to compute
8174 A - B only when B is initialized properly.
8175 * coding.c (coding_set_source, coding_set_destination): Return void.
8176 (coding_change_source, coding_change_destinations): New functions,
8177 with the old behaviors of coding_set_source and coding_set_destination.
8178 All callers that need an offset changed to use these new functions.
8180 2012-05-26 Glenn Morris <rgm@gnu.org>
8182 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
8184 2012-05-26 Eli Zaretskii <eliz@gnu.org>
8186 Extend mouse support on W32 text-mode console.
8187 * xdisp.c (draw_row_with_mouse_face):
8188 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
8190 * w32console.c: Include window.h.
8191 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
8193 (initialize_w32_display): Initialize mouse-highlight data.
8195 * w32inevt.c: Include termchar.h and window.h.
8196 (do_mouse_event): Support mouse-autoselect-window. When the mouse
8197 moves, call note_mouse_highlight. If help_echo changed, call
8198 gen_help_event to produce help-echo message in the echo area.
8199 Call clear_mouse_face if mouse_face_hidden is set in the mouse
8202 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
8204 * lread.c (read1): Simplify slightly to avoid an overflow warning

8210 definitely wide enough here.
8212 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
8214 Fix integer width and related bugs (Bug#9874).
8215 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
8216 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)

8225 (allocate_pseudovector):
8226 Use int, not EMACS_INT, where int is wide enough.
8227 (inhibit_garbage_collection, Fgarbage_collect):

8236 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8237 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
8238 (Fkill_buffer, Fset_buffer_major_mode)

8244 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
8245 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
8246 (Foverlay_recenter, last_overlay_modification_hooks_used)
8247 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
8248 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8249 (validate_region): Omit unnecessary test for b <= e,
8250 since that's guaranteed by the previous test.
8251 (adjust_overlays_for_delete): Avoid pos + length overflow.
8252 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
8253 (report_overlay_modification):
8254 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
8255 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
8256 Omit pointer cast, which isn't needed anyway, and doesn't work
8257 after the EMACS_INT -> ptrdiff_t change.
8258 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
8259 * buffer.h: Adjust decls to match defn changes elsewhere.

8264 not int, to avoid needless 32-bit limit on 64-bit hosts.
8265 (exec_byte_code): Use tighter memory-full test, one that checks
8266 for alloca overflow. Don't compute the address of the object just
8267 before an array, as that's not portable. Use EMACS_INT, not
8268 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
8269 * callint.c (Fcall_interactively):
8270 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

8281 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
8282 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8283 (casify_object): Avoid integer overflow when overallocating buffer.
8284 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
8285 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
8286 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
8287 * category.h (CATEGORYP): Don't assume arg is nonnegative.
8288 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
8289 integers are now checked earlier. All uses replaced with XINT.
8291 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8292 For CCL_MapSingle, check that content and value are in int range.
8293 (ccl_driver, Fregister_code_conversion_map):
8294 Check that Vcode_version_map_vector is a vector.
8295 (resolve_symbol_ccl_program): Check that vector header is in range.
8296 Always copy the vector, so that we can check its contents reliably
8297 now rather than having to recheck each instruction as it's being
8298 executed. Check that vector words fit in 'int'.
8299 (ccl_get_compiled_code, Fregister_ccl_program)
8300 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
8301 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
8302 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
8303 contents are in range.
8304 (Fccl_execute_on_string): Check that status is in range.
8305 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
8306 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
8307 Accept and return EMACS_INT, not int, because callers can pass values
8309 (c_string_width, strwidth, lisp_string_width, chars_in_text)
8310 (multibyte_chars_in_text, parse_str_as_multibyte)
8311 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)

8313 (string_escape_byte8, Fget_byte):
8314 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8315 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
8316 avoid mishandling large integers.
8317 * character.h: Adjust decls to match defn changes elsewhere.

8326 (Fdefine_charset_internal): Check ranges here, more carefully.
8327 Don't rely on undefined behavior with signed left shift overflow.
8328 Don't assume unsigned int fits into fixnum, or that fixnum fits
8329 into unsigned int. Don't require max_code to be a valid fixnum;
8330 that's not true for gb10830 4-byte on a 32-bit host. Allow
8331 invalid_code to be a cons, for the same reason. Require code_offset
8332 to be a character. Avoid int overflow if max_char is close
8334 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
8335 this is intended anyway and avoids some undefined behavior.
8336 (load_charset_map): Pass unsigned, not int, as 2nd arg of
8337 INDEX_TO_CODE_POINT, as that's what it expects.
8338 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
8339 * charset.h (DECODE_CHAR): Return int, not unsigned;
8340 this is what was intended anyway, and it avoids undefined behavior.
8341 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
8342 integer-overflow issues.
8343 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
8344 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
8345 where the argument is EMACS_INT, and this behavior is not intended.
8346 * chartab.c (Fmake_char_table, Fset_char_table_range)
8347 (uniprop_get_decoder, uniprop_get_encoder):
8348 Don't assume fixnum fits in int.
8349 * cmds.c (move_point): New function, that does the gist of
8350 Fforward_char and Fbackward_char, but does so while checking
8351 for integer overflow more accurately.
8352 (Fforward_char, Fbackward_char): Use it.
8353 (Fforward_line, Fend_of_line, internal_self_insert)
8354 (internal_self_insert):
8355 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8356 Fix a FIXME, by checking for integer overflow when calculating
8357 target_clm and actual_clm.

9014 2012-05-25 Glenn Morris <rgm@gnu.org>
9016 * lisp.mk (lisp): Update for more files being compiled now.
9018 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
9020 * lread.c: Remove `read_pure' which makes no difference.
9021 (read_pure): Remove var.
9022 (unreadpure): Remove function.
9023 (readevalloop): Don't call read_list with -1 flag.

9036 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
9038 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
9041 This directory predates autoconf and is no longer needed nowadays.
9042 Move its few remaining bits of functionality to where they're needed.

9052 (EMACS_UINT): Define unconditionally now.
9053 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
9054 (BITS_PER_EMACS_INT): New constants, replacing
9055 what used to be in config.h, but not useful in #if.
9056 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
9057 define them any more.
9058 (VAL_MAX): New macro.
9060 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
9061 BITS_PER_EMACS_INT, in #if.
9062 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
9063 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
9064 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
9065 * s/ms-w32.h (DATA_START):
9066 Move here from removed file m/intel386.h.
9067 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
9068 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
9070 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
9072 Assume C89 or later.
9073 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.

9081 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
9082 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
9083 * xterm.c (input_signal_count): Assume volatile works.
9085 2012-05-21 Ken Brown <kbrown@cornell.edu>
9087 * xgselect.c (xg_select): Fix first argument in call to 'select'
9090 2012-05-20 Ken Brown <kbrown@cornell.edu>
9092 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
9093 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
9095 2012-05-19 Ken Brown <kbrown@cornell.edu>
9097 * xfns.c (x_in_use): Remove `static' qualifier.
9098 * xterm.h (x_in_use): Declare.
9099 * xgselect.c: Include xterm.h.
9100 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
9101 and `display_arg' (bug#9754).
9103 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
9105 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
9107 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
9108 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
9110 2012-05-18 Eli Zaretskii <eliz@gnu.org>
9112 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
9114 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
9115 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
9117 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
9118 reference to image_cache->refcount.
9119 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
9121 2012-05-17 Juri Linkov <juri@jurta.org>
9123 * search.c (Fword_search_regexp, Fword_search_backward)
9124 (Fword_search_forward, Fword_search_backward_lax)
9125 (Fword_search_forward_lax): Move functions to isearch.el
9126 (bug#10145, bug#11381).
9128 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
9130 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
9132 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
9134 * lread.c (init_obarray): Declare Qt and Qnil as special.
9136 2012-05-14 Glenn Morris <rgm@gnu.org>
9138 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
9139 Put "libexec" before "bin", for the sake of init_callproc_1.
9141 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
9143 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
9145 * unexaix.c: Port to more-recent AIX compilers.
9146 (report_error, report_error_1, make_hdr, copy_sym)
9147 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
9148 Make arguments const char *, not char *, to avoid violations of C
9149 standard and to fix some AIX warnings reported by Gilles Pion.
9151 2012-05-14 Eli Zaretskii <eliz@gnu.org>
9153 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
9154 already have overlays loaded.
9155 (handle_single_display_spec): Before returning without displaying
9156 fringe bitmap, synchronize the bidi iterator with the main display
9157 iterator, by calling iterate_out_of_display_property.
9158 (iterate_out_of_display_property): Detect buffer iteration by
9159 testing that it->string is a Lisp string.
9160 (get_next_display_element): When the current object is exhausted,
9161 and there's something on it->stack, call set_iterator_to_next to
9162 proceed with what's on the stack, instead of returning zero.
9163 (set_iterator_to_next): If called at the end of a Lisp string,
9164 proceed to consider_string_end without incrementing string
9165 position. Don't increment display vector index past the end of
9166 the display vector. (Bug#11417)
9167 (pos_visible_p): Don't report a position visible when move_it_to
9168 stopped at the last line of window, which happens to be scanned
9169 backwards by the bidi iteration. (Bug#11464)
9171 2012-05-14 Eli Zaretskii <eliz@gnu.org>
9173 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
9174 and right-margin display specs even if the spec is invalid or we
9175 are on a TTY, and thus unable to display on the fringes.
9176 That's because the text with the property will not be displayed anyway,
9177 so we need to signal to the caller that this is a "replacing"
9178 display spec. This fixes display when the spec is invalid or we
9181 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
9183 * unexaix.c (make_hdr): Fix typo in prototype.
9184 This bug broke the build on AIX. Problem reported by Gilles Pion.
9186 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
9188 * keyboard.c (kbd_buffer_get_event): Read special events also in
9189 batch mode. (Bug#11415)
9191 2012-05-12 Glenn Morris <rgm@gnu.org>
9193 * ns.mk: Update for ns_appbindir no longer having trailing "/".
9195 2012-05-12 Eli Zaretskii <eliz@gnu.org>
9197 * lisp.mk (lisp): Add newcomment.elc.
9199 2012-05-12 Glenn Morris <rgm@gnu.org>
9201 * Makefile.in (MKDIR_P): New, set by configure.
9202 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
9204 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
9206 Remove unused function hourglass_started.
9207 * dispextern.h (hourglass_started):
9208 * w32fns.c (hourglass_started):
9209 * xdisp.c (hourglass_started): Remove.
9211 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
9213 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
9214 Update dependencies.
9216 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
9218 * xgselect.c (xg_select): Put maxfds+1 into a var.
9219 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
9221 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
9223 2012-05-10 Dave Abrahams <dave@boostpro.com>
9225 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
9226 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
9228 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
9230 * dbusbind.c (xd_registered_buses): New internal Lisp object.
9231 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
9232 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
9233 Initialize xd_registered_buses.
9235 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
9237 Untag more efficiently if USE_LSB_TAG.
9238 This is based on a proposal by YAMAMOTO Mitsuharu in
9239 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
9240 For an admittedly artificial (nth 8000 longlist) benchmark on
9241 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
9242 Emacs's overall text size by 1%.
9243 * lisp.h (XUNTAG): New macro.
9244 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
9245 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
9246 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
9247 * eval.c (Fautoload):
9248 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
9249 * frame.h (XFRAME): Use XUNTAG.
9251 Port recent dbusbind.c changes to 32-bit --with-wide-int.
9252 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
9253 Remove unportable assumptions about print widths of types like
9255 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
9256 intptr_t when converting between pointer and integer, to avoid GCC
9257 warnings about wrong width.
9259 2012-05-09 Eli Zaretskii <eliz@gnu.org>
9261 * w32proc.c (new_child): Force Windows to reserve only 64KB of
9262 stack for each reader_thread, instead of defaulting to 8MB
9263 determined by the linker. This avoids failures in creating
9264 subprocesses on Windows 7, see the discussion in this thread:
9265 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
9267 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
9269 Fix up display of the *Minibuf-0* buffer in the mini window.
9270 * keyboard.c (read_char): Don't clear the echo area if there's no
9272 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
9273 contents of *Minibuf-0*) if there's no message displayed in its stead.
9275 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
9277 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
9280 2012-05-06 Chong Yidong <cyd@gnu.org>
9282 * lisp.mk (lisp): Update.
9284 2012-05-05 Jim Meyering <meyering@redhat.com>
9286 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
9288 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
9290 * data.c (PUT_ERROR): New macro.
9291 (syms_of_data): Use it. Add new error type `user-error'.
9292 * undo.c (user_error): New function.
9293 (Fprimitive_undo): Use it.
9294 * print.c (print_error_message): Adjust print style for `user-error'.
9295 * keyboard.c (user_error): New function.
9296 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
9298 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
9300 Do not limit current-time-string to years 1000..9999.
9301 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
9302 (Fcurrent_time_string): Support any year that is supported by the
9303 underlying localtime representation. Don't use asctime, as it
9304 has undefined behavior for years outside the range -999..9999.
9306 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
9308 Fix race conditions involving setenv, gmtime, localtime, asctime.
9309 Without this fix, interrupts could mess up code that uses these
9310 nonreentrant functions, since setting TZ invalidates existing
9311 tm_zone or tzname values, and since most of these functions return
9312 pointers to static storage.
9313 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
9314 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
9315 Grow the critical sections to include not just invoking
9316 localtime/gmtime, but also accessing these functions' results
9317 including their tm_zone values if any, and any related TZ setting.
9318 (format_time_string): Last arg is now struct tm *, not struct tm **,
9319 so that the struct tm is saved in the critical section.
9320 All callers changed. Simplify allocation of initial buffer, partly
9321 motivated by the fact that memory allocation needs to be outside
9322 the critical section.

9340 * xdisp.c (pos_visible_p): If already at a newline from the
9341 display string before the 'while' loop, don't walk back the glyphs
9342 from it3.glyph_row. Solves assertion violation when the display

9350 2012-05-01 Glenn Morris <rgm@gnu.org>
9352 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
9353 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
9354 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).

9373 Do not avoid creating empty evaporating overlays (Bug#9642).
9374 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
9375 That is, do not delete an evaporating overlay if it becomes
9376 empty after its bounds are adjusted to fit within its buffer.
9377 This fix caused other problems, and I'm reverting it until we get
9378 to the bottom of them.
9380 2012-04-27 Chong Yidong <cyd@gnu.org>
9382 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).

9387 ZV, start the display from buffer beginning. Prevents assertion
9388 violation in init_iterator when the minibuffer window is scrolled
9391 * window.c (window_scroll_pixel_based): Likewise.
9393 2012-04-27 Chong Yidong <cyd@gnu.org>

9410 display element, check also the underlying string or buffer
9411 character. (Bug#11341)
9413 * w32menu.c: Include w32heap.h.
9414 (add_menu_item): If the call to AppendMenuW (via
9415 unicode_append_menu) fails, disable Unicode menus only if we are
9416 running on Windows 9X/Me.
9418 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
9420 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.

9423 2012-04-24 Martin Rudalics <rudalics@gmx.at>
9425 * keyboard.c (read_char): Don't wipe echo area for select window

9434 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
9436 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
9437 now a cons (bug#11311).
9439 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
9441 Do not create empty overlays with the evaporate property (Bug#9642).
9442 * buffer.c (Fmove_overlay): Delete an evaporating overlay
9443 if it becomes empty after its bounds are adjusted to fit within
9444 its buffer. Without this fix, in a nonempty buffer (let ((o
9445 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
9446 yields an empty overlay that has the evaporate property, which is
9447 not supposed to happen.
9449 Fix minor GTK3 problems found by static checking.

9725 gains a new, working vfork, we use it automatically (bug#10398).

9782 2012-04-09 Eli Zaretskii <eliz@gnu.org>
9784 * xdisp.c (set_cursor_from_row): If the display string appears in
9785 the buffer at position that is closer to point than the position
9786 after the display string, display the cursor on the first glyph of
9787 the display string. Fixes cursor display when a 'display' text
9788 property immediately follows invisible text. (Bug#11094)
9790 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
9792 composite.c: use 'double' consistently
9793 * composite.c (get_composition_id): Use 'double' consistently
9794 instead of converting 'float' to 'double' and vice versa; this is
9795 easier to understand and avoids a GCC warning.
9797 2012-04-09 Glenn Morris <rgm@gnu.org>
9799 * Makefile.in: Generate leim-list with bootstrap-emacs, in
9800 preparation for dumping it with emacs. (Bug#4789)
9801 (leimdir): New variable.
9802 ($(leimdir)/leim-list.el): New rule.
9803 (emacs$(EXEEXT)): Depend on leim-list.el.

9819 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
9821 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
9822 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
9823 (mark_memory): Mark Lisp_Objects only if pointers might hide in
9824 objects, as mark_maybe_pointer will catch them otherwise.
9825 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
9826 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
9828 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
9830 Fix typo that broke non-Windows builds.
9831 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
9833 2012-04-07 Eli Zaretskii <eliz@gnu.org>
9835 Support building on MS-Windows with libxml2.
9837 * makefile.w32-in (OBJ2): Add xml.$(O).
9838 (GLOBAL_SOURCES): Add xml.c.
9839 ($(BLD)/xml.$(O)): New dependency list.
9841 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
9842 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
9843 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
9844 [!WINDOWSNT]: New macros.
9845 (init_libxml2_functions, libxml2_loaded_p): New functions.
9846 (parse_region): Call fn_xmlCheckVersion instead of using the macro
9847 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
9848 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
9849 Calls xmlCleanupParser only if libxml2 was loaded (or statically
9851 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
9852 Call init_libxml2_functions before calling libxml2 functions.
9853 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
9855 * emacs.c: Don't include libxml/parser.h.
9856 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
9857 xmlCleanupParser directly.
9859 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
9861 2012-04-07 Eli Zaretskii <eliz@gnu.org>
9863 * indent.c (Fvertical_motion): If there is a display string at
9864 point, use it.vpos to compute how many lines to backtrack after
9865 move_it_to point. (Bug#11133)
9867 2012-04-06 Eli Zaretskii <eliz@gnu.org>
9869 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
9870 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
9871 about subtle differences between FETCH_CHAR* and STRING_CHAR*
9872 macros related to unification of CJK characters. For the details,
9873 see the discussion following the message here:
9874 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
9876 2012-04-04 Chong Yidong <cyd@gnu.org>
9878 * keyboard.c (Vdelayed_warnings_list): Doc fix.
9880 2012-04-01 Eli Zaretskii <eliz@gnu.org>
9882 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
9883 instead of alloca. (Bug#11138)
9885 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
9887 * w32menu.c (is_simple_dialog): Properly check lisp types.
9890 2012-03-31 Eli Zaretskii <eliz@gnu.org>
9892 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
9893 position we get to after a call to move_it_to fails the
9894 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
9895 only if we wind up in a string from display property. (Bug#11063)
9897 * window.c (Fdelete_other_windows_internal): Invalidate the row
9898 and column information about mouse highlight, so that redisplay
9899 restores it after reallocating the glyph matrices. (Bug#7464)
9901 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
9902 string comes from a `display' text property, use the buffer
9903 position of that property as if we actually saw that position in
9905 (move_it_by_lines): Remove the assertion that
9906 "it->current_x == 0 && it->hpos == 0" which can be legitimately
9907 violated when there's a before-string at the beginning of a line.
9910 2012-03-30 Eli Zaretskii <eliz@gnu.org>
9912 * xdisp.c (append_space_for_newline): If the default face was
9913 remapped, use the remapped face for the appended newline.
9914 (extend_face_to_end_of_line): Use the remapped default face for
9915 extending the face to the end of the line.
9916 (display_line): Call extend_face_to_end_of_line when the default
9917 face was remapped. (Bug#11068)
9919 2012-03-29 Eli Zaretskii <eliz@gnu.org>
9921 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
9923 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
9925 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
9927 2012-03-27 Glenn Morris <rgm@gnu.org>
9929 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
9932 2012-03-26 Kenichi Handa <handa@m17n.org>
9934 * dispextern.h (struct glyph): Fix previous change. Change the
9935 bit length of glyphless.ch to 25 (Bug#11082).
9937 2012-03-26 Chong Yidong <cyd@gnu.org>
9939 * keyboard.c (Vselection_inhibit_update_commands): New variable.
9940 (command_loop_1): Use it; inhibit selection update for
9941 handle-select-window too (Bug#8996).
9943 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
9945 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
9947 2012-03-25 Kenichi Handa <handa@m17n.org>
9949 * dispextern.h (struct glyph): Change the bit length of
9950 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
9952 2012-03-24 Eli Zaretskii <eliz@gnu.org>
9954 * s/ms-w32.h (tzname): Include time.h before redirecting to
9955 _tzname. Fixes the MSVC build. (Bug#9960)
9957 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
9959 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
9962 * xterm.c (XTread_socket): Only modify handling_signal if
9963 !SYNC_INPUT. (Bug#11080)
9965 2012-03-23 Eli Zaretskii <eliz@gnu.org>
9967 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
9968 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
9969 when fetching a multibyte character consumes more bytes than
9970 CHAR_BYTES returns, due to unification of CJK characters in
9971 string_char. (Bug#11073)
9973 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
9975 * process.c (wait_reading_process_output): Handle pty disconnect
9976 by refraining from sending oneself a SIGCHLD (bug#10933).
9978 2012-03-22 Chong Yidong <cyd@gnu.org>
9980 * dispextern.h (struct it): New member string_from_prefix_prop_p.
9982 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
9983 Mark string as coming from a prefix property.
9984 (handle_face_prop): Use default face for prefix strings (Bug#4281).
9985 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
9987 2012-03-21 Chong Yidong <cyd@gnu.org>
9989 * xfaces.c (Vface_remapping_alist): Doc fix.
9991 2012-03-20 Eli Zaretskii <eliz@gnu.org>
9993 * w32proc.c (Fw32_set_console_codepage)
9994 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
9997 2012-03-20 Chong Yidong <cyd@gnu.org>
9999 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
10000 to reflect default non-nil value of redisplay-dont-pause.
10002 2012-03-19 Kenichi Handa <handa@m17n.org>
10004 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
10005 it fit in a valid range (Bug#11003).
10007 2012-03-18 Eli Zaretskii <eliz@gnu.org>
10009 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
10010 that is not from display property, accept the row as a "cursor
10011 row" if one of the string's character has a non-nil `cursor'
10012 property. Fixes cursor positioning when there are newlines in
10013 overlay strings, e.g. in icomplete.el. (Bug#11035)
10015 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
10017 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
10019 2012-03-12 Chong Yidong <cyd@gnu.org>
10021 * eval.c (inhibit_lisp_code): Rename from
10022 inhibit_window_configuration_change_hook; move from window.c.
10024 * xfns.c (unwind_create_frame_1, Fx_create_frame):
10025 * window.c (run_window_configuration_change_hook)
10026 (syms_of_window): Callers changed.
10028 2012-03-11 Chong Yidong <cyd@gnu.org>
10030 * keymap.c (Fkey_description): Doc fix (Bug#9700).
10032 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
10034 2012-03-10 Chong Yidong <cyd@gnu.org>
10036 * frame.c (other_visible_frames): Don't assume the selected frame
10037 is visible (Bug#10955).
10039 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
10041 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).

10045 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
10046 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
10049 2012-03-03 Glenn Morris <rgm@gnu.org>
10051 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
10053 2012-03-02 Eli Zaretskii <eliz@gnu.org>
10055 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
10056 position past the first glyph_row that ends at ZV. (Bug#10902)
10057 (redisplay_window, next_element_from_string): Fix typos in
10059 (redisplay_window): Pass to move_it_vertically the margin in
10060 pixels, not in screen lines.
10062 2012-03-02 Glenn Morris <rgm@gnu.org>
10064 * buffer.c (buffer-list-update-hook): Doc fix.
10066 2012-02-29 Eli Zaretskii <eliz@gnu.org>
10068 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
10069 push_it before setting up the iterator for the first overlay
10070 string, even if we have an empty string loaded.
10071 (next_overlay_string): If there's an empty string on the iterator
10072 stack, pop the stack. (Bug#10903)
10074 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
10076 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
10077 Suggested by Stefan Monnier in
10078 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
10079 * alloc.c (widen_to_Lisp_Object): New static function.
10080 (mark_memory): Also mark Lisp_Objects by fetching pointer words
10081 and widening them to Lisp_Objects. This would work even if
10082 USE_LSB_TAG is defined and wide integers are used, which might
10083 happen in a future version of Emacs.
10085 2012-02-25 Chong Yidong <cyd@gnu.org>
10087 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
10090 * xselect.c (Fx_selection_exists_p): Doc fix.
10091 (x_clipboard_manager_save_all): Print an informative message
10092 before saving to clipboard manager.
10094 2012-02-24 Chong Yidong <cyd@gnu.org>
10096 * keyboard.c (process_special_events): Handle all X selection
10097 requests in kbd_buffer, not just the next one (Bug#8869).
10099 2012-02-23 Chong Yidong <cyd@gnu.org>
10101 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
10102 call when setting menu-bar-lines and tool-bar-lines parameters.
10103 (unwind_create_frame_1): New helper function.
10105 * window.c (inhibit_window_configuration_change_hook): New var.
10106 (run_window_configuration_change_hook): Obey it.
10107 (syms_of_window): Initialize it.
10109 2012-02-22 Chong Yidong <cyd@gnu.org>
10111 * xterm.c (x_draw_image_relief): Add missing type check for
10112 Vtool_bar_button_margin (Bug#10743).
10114 2012-02-21 Chong Yidong <cyd@gnu.org>
10116 * fileio.c (Vfile_name_handler_alist): Doc fix.
10118 * buffer.c (Fget_file_buffer): Protect against invalid file
10119 handler return value.
10121 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
10123 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
10124 when computing $valmask.
10126 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
10127 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
10128 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
10129 It's useless in that case, and it can cause problems on hosts
10130 that allocate halves of EMACS_INT values separately.
10131 Reported by Dan Horák. Diagnosed by Andreas Schwab in
10132 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
10133 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
10134 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
10135 it avoids undefined behavior on hosts where shifting right by more
10136 than the word width has undefined behavior.
10138 2012-02-19 Chong Yidong <cyd@gnu.org>
10140 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
10141 (Funhandled_file_name_directory, Ffile_name_as_directory)
10142 (Fdirectory_file_name, Fexpand_file_name)
10143 (Fsubstitute_in_file_name): Protect against invalid file handler
10144 return values (Bug#10845).
10146 2012-02-18 Eli Zaretskii <eliz@gnu.org>
10148 * .gdbinit (pitx): Fix incorrect references to fields of the
10151 2012-02-17 Chong Yidong <cyd@gnu.org>

10155 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
10157 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
10158 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
10160 2012-02-15 Chong Yidong <cyd@gnu.org>
10162 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
10163 marked as special. Also, starting docstrings with * is obsolete.
10165 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
10167 * gnutls.c (emacs_gnutls_write): Fix last change.

10176 * keymap.c (Fsingle_key_description): Handle char ranges.
10178 2012-02-12 Chong Yidong <cyd@gnu.org>
10180 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
10181 as that creates a dangerous corner case.
10183 * window.c (Fdelete_window_internal): Invalidate the mouse
10184 highlight (Bug#9904).
10186 2012-02-12 Glenn Morris <rgm@gnu.org>
10188 * xselect.c (Fx_own_selection_internal)
10189 (Fx_get_selection_internal, Fx_disown_selection_internal)
10190 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
10191 * nsselect.m (Fx_own_selection_internal)
10192 (Fx_disown_selection_internal, Fx_selection_exists_p)
10193 (Fx_selection_owner_p, Fx_get_selection_internal):
10194 Sync docs and argument specs with the xselect.c versions.
10196 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
10198 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
10200 2012-02-11 Eli Zaretskii <eliz@gnu.org>
10202 * w32select.c (Fx_selection_exists_p): Sync doc string and
10203 argument list with xselect.c. (Bug#10783)
10205 * w16select.c (Fx_selection_exists_p): Sync doc string and
10206 argument list with xselect.c. (Bug#10783)

10216 2012-02-07 Chong Yidong <cyd@gnu.org>
10218 * buffer.c (Fbuffer_local_variables)
10219 (buffer_lisp_local_variables): Handle unbound vars correctly;
10220 don't let Qunbound leak into Lisp.
10222 2012-02-07 Glenn Morris <rgm@gnu.org>
10224 * image.c (Fimagemagick_types): Doc fix.
10226 * image.c (imagemagick-render-type): Change it from a lisp object
10227 to an integer. Move the doc here from the lisp manual.
10228 Treat all values not equal to 0 the same.
10230 2012-02-06 Chong Yidong <cyd@gnu.org>
10232 * doc.c (store_function_docstring): Avoid applying docstring of
10233 alias to base function (Bug#2603).
10235 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>

10246 * w32.c (get_emacs_configuration_options):
10247 Include --enable-checking, if specified, in the return value.
10249 2012-02-04 Martin Rudalics <rudalics@gmx.at>
10251 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
10252 after rounding frame sizes. (Bug#9723)
10254 2012-02-04 Eli Zaretskii <eliz@gnu.org>
10256 * keyboard.c (adjust_point_for_property): Don't position point
10257 before BEGV. (Bug#10696)
10259 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
10261 Handle overflow when computing char display width (Bug#9496).
10262 * character.c (char_width): Return EMACS_INT, not int.
10263 (char_width, c_string_width): Check for overflow when
10264 computing the width; this is possible now that individual
10265 characters can have unbounded width. Problem introduced
10266 by merge from Emacs 23 on 2012-01-19.

10751 2011-11-30 Eli Zaretskii <eliz@gnu.org>
10753 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
10754 verifies glyph row's hash code--we have just reallocated the
10755 glyphs, so their contents can be complete garbage. (Bug#10164)
10757 2011-11-30 Juanma Barranquero <lekktu@gmail.com>
10759 * dispnew.c (adjust_glyph_matrix) [XASSERTS]: Add missing check.
10761 2011-11-30 Eli Zaretskii <eliz@gnu.org>
10763 * dispnew.c (adjust_glyph_matrix) [XASSERTS]: Ensure ROW's
10764 attributes are tested _before_ calling verify_row_hash, to protect
10765 against GCC re-ordering of the tests. (Bug#10164)
10767 2011-11-29 Jan Djärv <jan.h.d@swipnet.se>

10772 if net_wm_state_hidden_seen is non-zero (Bug#10002)
10773 (get_current_wm_state): Set net_wm_state_hidden_seen to 1 if
10774 _NET_WM_STATE_HIDDEN is in NET_WM_STATE.
10776 2011-11-28 Paul Eggert <eggert@cs.ucla.edu>
10778 Remove GCPRO-related macros that exist only to avoid shadowing locals.

10788 * dispnew.c (scrolling_window): Truncate overlaps in copy destination
10789 of scroll runs so as to avoid assigning disabled bogus rows and
10790 unnecessary graphics copy operations.
10792 2011-11-27 Eli Zaretskii <eliz@gnu.org>
10794 * s/ms-w32.h (utimbuf) [_MSC_VER]: Don't define.
10795 (snprintf) [_MSC_VER]: Redirect to _snprintf.
10796 (strtoll) [_MSC_VER]: Redirect to _strtoi64.
10797 (malloc, free, realloc, calloc): Redirect to e_* only when
10800 * lisp.h (GCTYPEBITS): Move before first use.
10801 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
10802 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in
10803 this macro definition.
10805 * s/ms-w32.h (tzname): Redirect to _tzname for all values of
10808 2011-11-27 Jan Djärv <jan.h.d@swipnet.se>
10810 * gtkutil.c (xg_create_frame_widgets):
10811 Call gtk_window_set_has_resize_grip (FALSE) if that function is

10821 Rename locals to avoid shadowing.
10822 * fileio.c (Finsert_file_contents):
10823 Rename inner 'gcpro1' to 'inner_gcpro1' to avoid shadowing.
10824 * process.c (wait_reading_process_output):
10825 Rename inner 'proc' to 'p' to avoid shadowing.
10826 Indent for consistency with usual Emacs style.
10828 2011-11-25 Eli Zaretskii <eliz@gnu.org>
10830 * xdisp.c (redisplay_window): If cursor row is not fully visible
10831 after recentering, and scroll-conservatively is set to a large
10832 number, scroll window by a few more lines to make the cursor fully
10833 visible and out of scroll-margin. (Bug#10105)
10834 (start_display): Don't move to the next line if the display should
10835 start at a newline that is part of a display vector or an overlay
10836 string. (Bug#10119)
10838 2011-11-24 Juri Linkov <juri@jurta.org>
10840 * image.c (imagemagick_load_image): Move `MagickSetResolution' down

10859 using it (Bug#5984).
10861 2011-11-22 Eli Zaretskii <eliz@gnu.org>
10863 * dispnew.c (adjust_glyph_matrix): Don't verify hash code of mode-
10864 and header-lines, as they don't have one computed for them.
10867 * .gdbinit (prow): Make displayed values more self-explaining.
10868 Add row's hash code.
10870 2011-11-21 Lars Magne Ingebrigtsen <larsi@gnus.org>

10913 2011-11-20 Paul Eggert <eggert@cs.ucla.edu>
10915 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
10916 Otherwise, valgrind does not work on some platforms.
10917 Problem reported by Andreas Schwab in
10918 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
10919 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
10920 is set, removing the need for VIRT_ADDRESS_VARIES.
10921 (PURE_P): Use a more-efficient implementation that needs just one
10922 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
10923 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
10924 to 4 (xorl, subq, cmpq, setbe).
10925 * alloc.c (pure): Always extern now, since that's the
10926 VIRT_ADDR_VARIES behavior.
10927 (PURE_POINTER_P): Use a single comparison, not two, for
10928 consistency with the new puresize.h.
10929 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
10930 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:
10931 Remove VIRT_ADDR_VARIES no longer needed.
10933 2011-11-19 Eli Zaretskii <eliz@gnu.org>
10935 * xdisp.c (x_write_glyphs, draw_phys_cursor_glyph)
10936 (erase_phys_cursor, update_window_cursor, show_mouse_face)
10937 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
10938 behave as if the cursor position were at the window margin.
10940 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
10941 and the cursor position is out of bounds, behave as if the cursor
10942 position were at the window margin. (Bug#10075)
10944 2011-11-18 Chong Yidong <cyd@gnu.org>
10946 * window.c (Fwindow_combination_limit): Make first argument
10947 non-optional, since it is meaningless for live windows like the

10959 2011-11-18 Eli Zaretskii <eliz@gnu.org>
10961 * dispnew.c (swap_glyph_pointers): Swap the used[] arrays and the
10962 hash values of the two rows.
10963 (copy_row_except_pointers): Preserve the used[] arrays and the
10964 hash values of the two rows. (Bug#10035)
10965 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
10967 * xdisp.c (row_hash): New function, body extracted from
10968 compute_line_metrics.
10969 (compute_line_metrics): Call row_hash, instead of computing the
10972 * dispnew.c (verify_row_hash): Call row_hash for computing the
10973 hash code of a row, instead of duplicating code from xdisp.c.
10975 * dispextern.h (row_hash): Add prototype.
10977 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
10979 * frame.c (delete_frame): Don't delete the terminal when the last
10980 X frame is closed if emacs is built with GTK toolkit.

10995 * nsfns.m (Fns_font_name):
10996 * window.c (syms_of_window) <window-combination-limit>: Fix typos.
10998 2011-11-16 Martin Rudalics <rudalics@gmx.at>
11000 * window.h (window): Rename slot "nest" to "combination_limit".
11001 * window.c (Fwindow_nest): Rename to Fwindow_combination_limit.
11002 (Fset_window_nest): Rename to Fset_window_combination_limit.
11003 (Vwindow_nest): Rename to Vwindow_combination_limit.
11004 (recombine_windows, make_parent_window, make_window)
11005 (Fsplit_window_internal, saved_window)
11006 (Fset_window_configuration, save_window_save): Rename all
11007 occurrences of window_nest to window_combination_limit.
11009 2011-11-15 Juanma Barranquero <lekktu@gmail.com>
11011 * image.c (imagemagick_load_image): Fix typo.
11013 2011-11-14 Eli Zaretskii <eliz@gnu.org>
11015 * xdisp.c (display_line): Move the call to
11016 highlight_trailing_whitespace before the call to
11017 compute_line_metrics, since the latter needs to see the final
11018 faces of all the glyphs to compute ROW's hash value.
11019 Fixes assertion violations in row_equal_p. (Bug#10035)
11021 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
11023 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
11024 just return (bug#10044).
11026 2011-11-12 Eli Zaretskii <eliz@gnu.org>
11028 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
11029 with user-defined heap size. Bump the default size of the temacs
11030 heap to 27MB, to avoid memory warning when running temacs.
11031 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
11033 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
11034 current_matrix and desired_matrix. (Bug#9990)
11035 (verify_row_hash) [XASSERTS]: New function.
11036 (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify
11037 that the hash value of glyph rows is correct.

11053 * nsfns.m (unwind_create_frame):
11054 * w32fns.c (unwind_create_frame): Use Fmemq to check if frame is in
11055 Vframe_list (Bug#9999).

11066 2011-11-11 Johan Bockgård <bojohan@gnu.org>
11068 * xdisp.c (fill_composite_glyph_string): Always set s->face, to
11069 avoid a crash (bug#9496).
11071 2011-11-09 Chong Yidong <cyd@gnu.org>
11073 * window.c (Fwindow_inside_edges, Fwindow_inside_pixel_edges)

11080 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
11082 Avoid some portability problems by eschewing 'extern inline' functions.
11083 The trivial performance wins aren't worth the portability hassles; see
11084 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
11086 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
11087 (window_box_width, window_box_left, window_box_left_offset)
11088 (window_box_right, window_box_right_offset): Undo previous change,
11089 by removing the "extern"s.
11090 * intervals.c (adjust_intervals_for_insertion)
11091 (adjust_intervals_for_deletion): Undo previous change,
11092 making these static again.
11093 (offset_intervals, temp_set_point_both, temp_set_point)
11094 (copy_intervals_to_string): No longer inline.
11095 * xdisp.c (window_text_bottom_y, window_box_width)
11096 (window_box_height, window_box_left_offset)
11097 (window_box_right_offset, window_box_left, window_box_right)
11098 (window_box): No longer inline.

11123 * window.c (Fwindow_nest, Fset_window_nest)
11124 (Fset_window_new_total, Fset_window_new_normal)
11125 (Fwindow_resize_apply): Don't use term subwindow in doc-strings.
11126 (delete_all_subwindows): Rename to delete_all_child_windows.
11127 (Fdelete_other_windows_internal, Fset_window_configuration):
11128 Call delete_all_child_windows instead of delete_all_subwindows.
11129 * frame.c (delete_frame): Call delete_all_child_windows instead
11130 of delete_all_subwindows.
11132 2011-11-07 Paul Eggert <eggert@cs.ucla.edu>
11134 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
11135 This is also needed for porting to any host where GC_MARK_STACK is
11136 not GC_MAKE_GCPROS_NOOPS.
11137 (which_symbols): Use it.
11139 2011-11-07 Kenichi Handa <handa@m17n.org>
11141 * coding.c (coding_set_destination): Check coding->src_pos only
11142 when coding->src_object is a buffer (bug#9910).

11148 process_coding to 0 (bug#9912).
11150 2011-11-06 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11152 * xmenu.c (cleanup_widget_value_tree): New function.
11153 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
11154 calling free_menubar_widget_value_tree directly (Bug#9830).
11156 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
11158 Fix some portability problems with 'inline'.
11159 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
11160 (window_box_width, window_box_left, window_box_left_offset)
11161 (window_box_right, window_box_right_offset): Declare extern.
11162 Otherwise, these inline functions do not conform to C99 and
11163 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
11164 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
11165 * intervals.c (adjust_intervals_for_insertion)
11166 (adjust_intervals_for_deletion): Now extern, because otherwise the
11167 extern inline functions 'offset_intervals' couldn't refer to it.
11168 (static_offset_intervals): Remove.
11169 (offset_intervals): Rewrite using the old contents of
11170 static_offset_intervals. The old version didn't conform to C99
11171 because an extern inline function contained a reference to an
11172 identifier with static linkage.
11174 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
11176 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

11181 * xdisp.c (init_iterator, reseat_to_string): Don't set the
11182 iterator's bidi_p flag if Vpurify_flag is non-nil. (Bug#9963)
11183 (Fcurrent_bidi_paragraph_direction): If Vpurify_flag is non-nil,
11184 return Qleft_to_right.

11193 (Fwindow_margins, Fwindow_fringes, Fwindow_scroll_bars)
11194 (Fwindow_vscroll): Doc fix.
11195 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
11196 argument, since it makes no sense to pass a live window and for
11197 consistency with window-child.

11407 (w32font_open_internal, compute_metrics):
11408 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
11409 instead of calling the "wide" APIs directly.
11411 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
11413 * w32.h (syms_of_w32font): Add prototype.

11424 * process.c (make_process): Set gnutls_state to NULL.
11426 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
11427 non-NULL, regardless of GNUTLS_INITSTAGE.

11462 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
11464 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>

11467 terminal (Bug#6649).
11469 2011-10-20 Eli Zaretskii <eliz@gnu.org>
11471 * dispextern.h (struct bidi_it): New member next_en_type.
11473 * bidi.c (bidi_line_init): Initialize the next_en_type member.
11474 (bidi_resolve_explicit_1): When next_en_pos is valid for the
11475 current character, check also for next_en_type being WEAK_EN.
11476 (bidi_resolve_weak): Don't enter the expensive loop if the current
11477 position is before next_en_pos. Record the bidi type of the first
11478 non-ET, non-BN character we find, in addition to its position.
11479 (bidi_level_of_next_char): Invalidate next_en_type when
11480 next_en_pos is over-stepped.
11482 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
11484 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
11485 * editfns.c: Rewrite current-time-zone so that it invokes
11486 the equivalent of (format-time-string "%Z") to get the time zone name.
11487 This fixes a bug when the time zone name contains characters that
11488 need converting from the system time locale to Emacs internal format.
11489 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
11490 that patch fixed format-time-string to do the conversion, but
11491 I forgot to fix current-time-zone.
11492 (format_time_string): New function, containing most of
11493 what Fformat_time_string used to contain.
11494 (Fformat_time_string): Rewrite in terms of format_time_string.
11495 This doesn't change this function's behavior.
11496 (current-time-zone): Rewrite to use format_time_string.
11497 This fixes the bug reported by Michael Schierl in
11498 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
11499 Jason Rumney's 2007-06-07 change worked around this bug, but
11501 * systime.h (tzname, timezone): Remove no-longer-used declarations.
11503 2011-10-19 Eli Zaretskii <eliz@gnu.org>
11505 * xdisp.c (start_display): If the character at POS is displayed
11506 via a display vector, reset IT->current.dpvec_index to zero.
11507 (try_window_reusing_current_matrix): If a line ends in a display
11508 vector or the next line starts in a display vector, continue
11509 redrawing the window even though the character position of
11510 start_row was reached.
11513 2011-10-18 Chong Yidong <cyd@gnu.org>
11515 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
11516 with nobreak-char-display too.
11518 2011-10-18 Eli Zaretskii <eliz@gnu.org>
11520 Fix part 3 of bug#9771.
11521 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
11522 (bidi_resolve_neutral): Don't enter the expensive loop looking for
11523 non-neutral characters if the current character is a paragraph
11524 separator (a.k.a. Newline). This avoids running the same
11525 expensive loop twice, once when we consume the preceding newline
11526 and the other time when the line actually needs to be displayed.
11527 Avoid the loop when we see neutrals on the base embedding level
11528 following a character whose directionality is the same as the
11529 paragraph's. This avoids running the expensive loop when a line
11530 ends in a long sequence of neutrals, like control characters.
11531 Add assertion against STRONG_AL type. Slightly rearrange code
11532 that determines the type of a neutral given the first non-neutral
11534 (bidi_level_of_next_char): Set next_en_pos to zero when
11535 invalidating its info.
11537 2011-10-17 Eli Zaretskii <eliz@gnu.org>
11539 * xdisp.c (push_display_prop): Determine whether to record string
11540 or buffer position by IT->string, not by IT->method. Allow
11541 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
11542 (move_it_vertically_backward): Don't look for character position
11543 immediately after the newline when in a continuation line.
11546 2011-10-15 Martin Rudalics <rudalics@gmx.at>
11548 * window.c (coordinates_in_window): Rewrite and delabelize
11549 vertical border check. (Bug#5357) (Bug#9618)
11551 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
11553 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
11554 errors in XSetWindowBorder (bug#9310).
11556 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
11558 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
11559 avoid crash when xmalloc overrun checking is enabled.
11561 2011-10-13 Eli Zaretskii <eliz@gnu.org>
11563 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
11564 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
11565 cursor motion with <left> and <right> arrow keys.
11567 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
11568 some callers set that themselves.
11570 2011-10-12 Eli Zaretskii <eliz@gnu.org>
11572 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
11573 display string and the previous row comes from the same string and
11574 is empty. (Bug#9739) (Bug#9738)
11576 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
11578 * doc.c (get_doc_string): Encode file name (bug#9735).
11580 2011-10-12 Eli Zaretskii <eliz@gnu.org>
11582 * bidi.c (bidi_level_of_next_char):
11583 * xdisp.c (get_visually_first_element): Remove old incorrect
11584 comments regarding the Unicode Line Separator character.
11586 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
11588 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
11590 * alloc.c (Fgc_status): Do not access beyond zombies array
11591 boundary if nzombies > MAX_ZOMBIES.
11592 * alloc.c (dump_zombies): Add missing format specifier.
11594 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
11596 * xdisp.c (set_cursor_from_row): Simplify conditionals,
11597 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
11599 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
11600 Some packages use them to denote characters with modifiers.
11602 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
11604 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
11605 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
11606 matching a pp-number. Rename parameter var to var1.
11608 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
11610 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
11612 2011-10-08 Glenn Morris <rgm@gnu.org>
11614 * callint.c (Fcall_interactively): Give a more explicit error for the
11615 'c' case with a non-character input. (Bug#8479)
11617 2011-10-08 Eli Zaretskii <eliz@gnu.org>
11619 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
11621 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
11622 lines that are hscrolled on the left.

11627 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
11629 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
11630 Don't advertise functionality which we discourage or doesn't work.
11632 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
11634 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
11635 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
11636 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
11637 this makes Emacs dump core during garbage collection on rare
11638 occasions. sizeof is obviously inferior to offsetof here, so
11639 stick with offsetof.
11640 (GC_POINTER_ALIGNMENT): New macro.
11641 (mark_memory): Omit 3rd (offset) arg; caller changed.
11642 Don't assume EMACS_INT alignment is the same as pointer alignment.
11644 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
11646 * keyboard.c (read_key_sequence_remapped): New var.
11647 (read_key_sequence): Compute remapping in the right buffer.
11648 (command_loop_1): Use read_key_sequence's remapping directly.
11650 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
11652 * dired.c (file_name_completion): Don't expand file name.
11653 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
11654 before checking file name handler.
11656 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
11657 they've been requested explicitly (bug#9591).
11659 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
11661 * keymap.c (Fsingle_key_description): Use make_specified_string
11662 instead of build_string to build string from push_key_description.
11665 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
11667 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
11668 This fixes a Y2038 bug on 64-bit hosts.
11669 * buffer.c (reset_buffer):
11670 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
11671 (Fclear_buffer_auto_save_failure):
11672 Use 0, not -1, to represent an unset failure time, since time_t
11673 might not be signed.
11675 Remove dependency on glibc malloc internals.
11676 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11677 Move back here from lisp.h, but with their new implementations.
11678 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11679 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
11680 * charset.c (charset_table_init): New static var.
11681 (syms_of_charset): Use it instead of xmalloc. This removes a
11682 dependency on glibc malloc internals. See Eli Zaretskii's comment in
11683 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
11684 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11685 Move back to alloc.c.
11686 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11687 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
11689 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
11691 * nsterm.m (windowDidResize): Call x_set_window_size only when
11692 ns_in_resize is true. Otherwise set pixelwidth/height and
11693 call change_frame_size (Bug#9628).
11695 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
11697 Port --enable-checking=all to Fedora 14 x86-64.
11698 * charset.c (syms_of_charset): Also account for glibc malloc's
11699 internal overhead when calculating the initial malloc maximum.
11701 Port --enable-checking=all to Fedora 14 x86.
11702 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11704 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
11705 (overrun_check_realloc, overrun_check_free):
11706 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
11707 That way, xmalloc returns a properly-aligned pointer even if
11708 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
11709 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
11710 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
11711 into account when calculating the initial malloc maximum.
11712 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11713 Move here from alloc.c, so that charset.c can use it too.
11714 Properly align; the old code wasn't right for common 32-bit hosts
11715 when configured with --enable-checking=all.
11716 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11717 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
11719 2011-09-29 Eli Zaretskii <eliz@gnu.org>
11721 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
11724 2011-09-28 Eli Zaretskii <eliz@gnu.org>
11726 * xdisp.c (compute_display_string_end): If there's no display
11727 string at CHARPOS, return -1.
11729 * bidi.c (bidi_fetch_char): When compute_display_string_end
11730 returns a negative value, treat the character as a normal
11731 character not covered by a display string. (Bug#9624)
11733 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
11735 * lread.c (Fread_from_string): Fix typo in docstring.
11737 2011-09-27 Eli Zaretskii <eliz@gnu.org>
11739 * xdisp.c (handle_invisible_prop): If invisible text ends on a
11740 newline, reseat the iterator instead of bidi-iterating there one
11741 character at a time. (Bug#9610)
11742 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
11743 TO_CHARPOS if the bidi iterator is at base embedding level.
11745 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
11747 * lread.c (readevalloop): Use correct code for NBSP.
11748 (read1): Likewise. (Bug#9608)
11750 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
11752 * dbusbind.c (Fdbus_register_signal): When service is not
11753 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
11755 2011-09-25 Glenn Morris <rgm@gnu.org>
11757 * buffer.c (truncate-lines): Doc fix.
11759 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
11761 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
11762 (Fset_window_next_buffers): Doc fix.
11764 2011-09-24 Glenn Morris <rgm@gnu.org>
11766 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
11768 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
11770 Fix minor problems found by static checking.
11771 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
11772 * indent.c (Fvertical_motion): Fix == vs = typo.
11774 2011-09-24 Eli Zaretskii <eliz@gnu.org>
11776 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
11777 Default value is now t. Doc fix.
11779 * indent.c (Fvertical_motion): Compute and apply the overshoot
11780 logic when moving up, not only when moving down. Fix the
11781 confusing name and values of the it_overshoot_expected variable;
11782 logic changes accordingly. (Bug#9254) (Bug#9549)
11784 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
11785 CHARPOS is covered by a display string which includes newlines.
11786 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
11787 is covered by a display string with embedded newlines.
11789 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
11791 * dbusbind.c (Fdbus_register_signal): Add match rule to
11792 Vdbus_registered_objects_table. (Bug#9581)
11793 (Fdbus_register_method, Vdbus_registered_objects_table):
11796 2011-09-24 Jim Meyering <meyering@redhat.com>
11798 do not ignore write error for any output size
11799 The previous change was incomplete.
11800 While it makes emacs --batch detect the vast majority of stdout
11801 write failures, errors were still ignored whenever the output size is
11802 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
11803 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
11804 && echo FAIL: ignored write error
11805 FAIL: ignored write error
11806 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
11807 && echo FAIL: ignored write error
11808 FAIL: ignored write error
11809 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
11811 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
11813 * emacs.c (Fkill_emacs): In noninteractive mode exit
11814 non-successfully if a write error occurred on stdout. (Bug#9574)
11816 2011-09-21 Eli Zaretskii <eliz@gnu.org>
11818 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
11821 * dispextern.h (struct it): Update the comment documenting what
11824 2011-09-20 Eli Zaretskii <eliz@gnu.org>
11826 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
11827 a display string, extend search for cursor position to end of row.
11828 (find_row_edges): If the row ends in a newline from a display
11829 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
11830 Handle the case of a display string with multiple newlines.
11831 (Fcurrent_bidi_paragraph_direction): Fix search for previous
11832 non-empty line. Fixes confusing cursor motion with arrow keys at
11833 the beginning of a line that starts with whitespace.
11835 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
11837 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
11840 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
11842 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
11843 boolean (Bug#9154).
11845 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11847 * xdisp.c (display_line): Record maximum and minimum buffer
11848 positions even if no glyphs were produced (e.g., by a zero-width
11849 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
11850 buffer positions that will be removed from the glyph row because
11852 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
11853 column is beyond frame width: don't subtract 1 "pixel" when
11854 computing width of the stretch.
11855 (reseat_at_next_visible_line_start): Undo the change made on
11856 2011-09-17 that saved paragraph information and restored it after
11857 the call to `reseat'. (Bug#9545)
11859 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11861 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
11862 and turn window cursor on if cleared (Bug#9415).
11864 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
11866 * search.c (boyer_moore): Take unibyte characters from pattern
11867 literally. (Bug#9458)
11869 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11871 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
11873 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
11875 Fix minor problem found by static checking.
11876 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
11877 initialized, to pacify gcc -Wuninitialized.
11879 * fileio.c: Report proper errno when syscall falls.
11880 (Finsert_file_contents): Save and restore errno,
11881 so that report_file_error outputs the correct diagnostic.
11882 (Fwrite_region) [CLASH_DETECTION]: Likewise.
11884 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11886 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
11888 2011-09-17 Eli Zaretskii <eliz@gnu.org>
11890 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
11891 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
11893 2011-09-17 Eli Zaretskii <eliz@gnu.org>
11895 * xdisp.c (reseat_at_next_visible_line_start): Keep information
11896 about the current paragraph and restore it after the call to reseat.
11898 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
11899 (bidi_find_paragraph_start): Search back for paragraph beginning
11900 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
11901 (bidi_move_to_visually_next): Only trigger paragraph-related
11902 computations when the last character is a newline or at EOB, not
11903 just any NEUTRAL_B. (Bug#9470)
11905 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
11906 truncated lines if point is covered by a display string. (Bug#9524)
11908 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
11910 * xselect.c: Relax test for outgoing X longs (Bug#9498).
11911 (cons_to_x_long): New function.
11912 (lisp_data_to_selection_data): Use it. Correct the test for
11913 short-versus-long data; it was negated. Break out of vector
11914 loop, for efficiency, when a long datum is discovered.
11916 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
11918 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
11920 2011-09-16 Eli Zaretskii <eliz@gnu.org>
11922 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
11923 GCC PR/17406) by declaring this function with external scope.
11925 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
11927 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
11928 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
11930 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
11932 * editfns.c (Fformat): Correctly handle text properties on "%%".

11938 * term.c (encode_terminal_code):
11939 * composite.c (composition_update_it, get_composition_id):
11940 * xdisp.c (get_next_display_element)
11941 (fill_composite_glyph_string): Add comments about special meaning
11942 of TAB characters in a composition.
11944 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
11946 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
11947 This occurs when processing a multibyte format.
11948 Problem reported by Wolfgang Jenker.
11950 2011-09-15 Johan Bockgård <bojohan@gnu.org>
11952 * xdisp.c (try_cursor_movement): Only check for exact match if
11953 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
11955 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
11957 Remove unused external symbols.
11958 * dispextern.h (calc_pixel_width_or_height): Remove decl.
11959 * xdisp.c (calc_pixel_width_or_height): Now static.
11960 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
11961 * indent.c (check_display_width):
11962 * w32term.c: Fix comment to match code.
11963 * xterm.c, xterm.h (x_catching_errors): Remove.
11965 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
11967 * xselect.c: Use signed conversions more consistently (Bug#9498).
11968 (selection_data_to_lisp_data): Assume incoming selection data are
11969 signed integers, not unsigned. This is to be consistent with
11970 outgoing selection data, which was modified to use signed integers
11971 in as part of the fix to Bug#9196 in response to Jan D.'s comment
11972 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
11973 expects long, not unsigned long.
11975 2011-09-14 Eli Zaretskii <eliz@gnu.org>
11977 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
11978 computation of loop end. Reported by Johan Bockgård
11981 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
11983 * frame.c (Fother_visible_frames_p): Function deleted.
11985 2011-09-12 Eli Zaretskii <eliz@gnu.org>
11987 * indent.c (compute_motion): Process display vector front to back
11988 rather than the other way around. (Bug#2496)
11990 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
11992 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
11994 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
11996 * minibuf.c (Fread_from_minibuffer): Doc fix.
11998 2011-09-11 Eli Zaretskii <eliz@gnu.org>
12000 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
12001 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
12003 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
12005 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
12006 value for non-existent files.
12008 2011-09-11 Eli Zaretskii <eliz@gnu.org>
12010 * fileio.c (Finsert_file_contents): If the file cannot be opened,
12011 set its "size" to -1. This will set the modtime_size field of
12012 the corresponding buffer to -1, which is what
12013 verify-visited-file-modtime expects for files that do not exist.
12016 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
12018 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
12020 * lisp.h: ... from here. push_key_description is no longer
12021 defined in keyboard.c, so its declaration should not be in
12022 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
12023 logically belongs with push_key_description.
12025 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
12027 * buffer.h: Include <sys/types.h> instead of <time.h>.
12028 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
12029 Problem reported by Herbert J. Skuhra.
12031 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
12033 * xml.c (parse_region): Make the parsing work for
12034 non-comment-starting XML files again (bug#9144).
12036 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
12038 * image.c (gif_load): Fix calculation of bottom and right corner.
12041 2011-09-10 Eli Zaretskii <eliz@gnu.org>
12043 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
12044 redisplay in small windows.
12046 2011-09-09 Eli Zaretskii <eliz@gnu.org>
12048 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
12050 2011-09-08 Martin Rudalics <rudalics@gmx.at>
12052 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
12053 Operate on live windows only.
12055 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
12057 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
12059 2011-09-07 Eli Zaretskii <eliz@gnu.org>
12061 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
12062 only under bidi iteration.
12064 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
12066 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
12068 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12070 isnan: Fix porting problem to Solaris 10 with bundled gcc.
12071 Without this fix, the command to link temacs failed due to an
12072 undefined symbol __builtin_isnan. This is because
12073 /usr/include/iso/math_c99.h #defines isnan(x) to
12074 __builtin_isnan(x), but the bundled gcc, which identifies itself
12075 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
12077 * floatfns.c (isnan): #undef, and then #define to a clone of
12079 (Fisnan): Always define, since it's always available now.
12080 (syms_of_floatfns): Always define isnan at the Lisp level.
12082 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12084 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
12086 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12088 * fileio.c: Fix bugs with large file offsets (Bug#9428).
12089 The previous code assumed that file offsets (off_t values) fit in
12090 EMACS_INT variables, which is not true on typical 32-bit hosts.
12091 The code messed up by falsely reporting buffer overflow in cases
12092 such as (insert-file-contents "big" nil 1 2) into an empty buffer
12093 when "big" contains more than 2**29 bytes, even though this
12094 inserts just one byte and does not overflow the buffer.
12095 (Finsert_file_contents): Store file offsets as off_t
12096 values, not as EMACS_INT values. Check for overflow when
12097 converting between EMACS_INT and off_t. When checking for
12098 buffer overflow or for overlap, take the offsets into account.
12099 Don't use EMACS_INT for small values where int suffices.
12100 When checking for overlap, fix a typo: ZV was used where
12101 ZV_BYTE was intended.
12102 (Fwrite_region): Don't assume off_t fits into 'long'.
12103 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
12105 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
12107 * dbusbind.c (xd_signature_cat): Rename from signature_cat.

12111 sprintf-related integer and memory overflow issues (Bug#9412).
12113 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
12114 (esprintf, exprintf, evxprintf): New functions.
12115 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
12116 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
12117 (modify_event_symbol): Do not assume that the length of
12118 name_alist_or_stem is safe to alloca and fits in int.
12119 (Fexecute_extended_command): Likewise for function name and binding.
12120 (Frecursion_depth): Wrap around reliably on integer overflow.
12121 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
12122 since some callers pass EMACS_INT values.
12123 (Fsingle_key_description): Don't crash if symbol name contains more
12124 than MAX_ALLOCA bytes.
12125 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
12126 (get_minibuffer): Arg is now EMACS_INT, not int.
12127 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
12128 (esprintf, exprintf, evxprintf): New decls.
12129 * window.h (command_loop_level, minibuf_level): Reflect API changes.
12131 * dbusbind.c (signature_cat): New function.
12132 (xd_signature, Fdbus_register_signal):
12133 Do not overrun buffer; instead, report string overflow.
12135 * dispnew.c (add_window_display_history): Don't overrun buffer.
12136 Truncate instead; this is OK since it's just a log.
12138 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
12139 even if the time zone offset is outlandishly large.
12140 Don't mishandle offset == INT_MIN.
12142 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
12143 when creating daemon; the previous buffer-overflow check was incorrect.
12145 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
12146 which has the guts of the old verror function.
12148 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
12149 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
12151 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
12152 (font_unparse_xlfd): Don't blindly alloca long strings.
12153 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
12154 fits in int, when using sprintf. Use single snprintf to count
12155 length of string rather than counting it via multiple sprintfs;
12156 that's simpler and more reliable.
12157 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
12158 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
12159 sprintf, in case result does not fit in int.
12161 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
12162 (fontset_from_font): Print it.
12164 * frame.c (tty_frame_count): Now printmax_t, not int.
12165 (make_terminal_frame, set_term_frame_name): Print it.
12166 (x_report_frame_params): In X, window IDs are unsigned long,
12167 not signed long, so print them as unsigned.
12168 (validate_x_resource_name): Check for implausibly long names,
12169 and don't assume name length fits in 'int'.
12170 (x_get_resource_string): Don't blindly alloca invocation name;
12171 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
12174 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
12175 (xg_check_special_colors, xg_set_geometry):
12176 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
12178 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
12179 Use esprintf, not sprintf, in case result does not fit in int.
12181 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
12182 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
12183 it as a large positive number.
12184 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
12185 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
12187 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
12188 in case result does not fit in int.
12190 * print.c (float_to_string): Detect width overflow more reliably.
12191 (print_object): Make sprintf buffer a bit bigger, to avoid potential
12192 buffer overrun. Don't assume list length fits in 'int'. Treat
12193 print length of 0 as 0, not as infinity; to be consistent with other
12194 uses of print length in this function. Don't overflow print length
12195 index. Don't assume hash table size fits in 'long', or that
12196 vectorlike size fits in 'unsigned long'.
12198 * process.c (make_process): Use printmax_t, not int, to format
12199 process-name gensyms.
12201 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
12203 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
12204 to avoid potential buffer overrun.
12206 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
12207 if X resource line is longer than 512 bytes.
12209 * xfns.c (x_window): Make sprintf buffer a bit bigger
12210 to avoid potential buffer overrun.
12212 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
12214 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
12216 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
12218 Integer overflow fixes for scrolling, etc.
12219 Without these, Emacs silently mishandles large integers sometimes.
12220 For example, "C-u 4294967297 M-x recenter" was treated as if
12221 it were "C-u 1 M-x recenter" on a typical 64-bit host.
12223 * xdisp.c (try_window_id): Check Emacs fixnum range before
12224 converting to 'int'.
12226 * window.c (window_scroll_line_based, Frecenter):
12227 Check that an Emacs fixnum is in range before assigning it to 'int'.
12228 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
12229 values converted from Emacs fixnums.
12230 (Frecenter): Don't wrap around a line count if it is out of 'int'
12231 range; instead, treat it as an extreme value.
12232 (Fset_window_configuration, compare_window_configurations):
12233 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
12235 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
12236 that can exceed INT_MAX. Check that EMACS_INT value is in range
12237 before assigning it to the (possibly-narrower) index.
12238 (match_limit): Don't assume that a fixnum can fit in 'int'.
12240 * print.c (print_object): Use ptrdiff_t, not int, for index that can
12243 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
12244 (Fvertical_motion): Don't wrap around LINES values that don't fit
12245 in 'int'. Instead, treat them as extreme values. This is good
12246 enough for windows, which can't have more than INT_MAX lines anyway.
12248 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
12250 * Require libxml/parser.h to avoid compilation warning.
12252 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
12254 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
12255 since this reportedly can destroy thread storage.
12257 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
12259 * syntax.c (find_defun_start): Update all cache variables if
12260 exiting early (Bug#9401).
12262 2011-08-30 Eli Zaretskii <eliz@gnu.org>
12264 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
12266 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
12267 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
12268 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
12270 * term.c (tty_append_glyph): New function.
12271 (produce_stretch_glyph): Static function and its prototype deleted.
12273 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
12276 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
12278 * image.c (parse_image_spec): Check for nonnegative, not for positive,
12279 when checking :margin (Bug#9390).
12280 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
12281 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
12282 so that the name doesn't mislead. All uses changed.
12284 2011-08-28 Johan Bockgård <bojohan@gnu.org>
12286 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
12289 2011-08-27 Eli Zaretskii <eliz@gnu.org>
12291 * xdisp.c (move_it_to): Don't bail out early when reaching
12292 position beyond to_charpos, if we are scanning backwards.
12293 (move_it_vertically_backward): When DY == 0, make sure we get to
12294 the first character in the line after the newline.
12296 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
12298 * ccl.c: Improve and simplify overflow checking (Bug#9196).
12299 (ccl_driver): Do not generate an out-of-range pointer.
12300 (Fccl_execute_on_string): Remove unnecessary check for
12301 integer overflow, noted by Stefan Monnier in
12302 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
12303 Remove a FIXME that didn't need fixing.
12304 Simplify the newly-introduced buffer reallocation code.
12306 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
12308 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
12310 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
12312 Integer and memory overflow issues (Bug#9196).
12314 * doc.c (get_doc_string): Rework so that
12315 get_doc_string_buffer_size is the actual buffer size, rather than
12316 being 1 less than the actual buffer size; this makes xpalloc more
12319 * image.c (x_allocate_bitmap_record, cache_image):
12320 * xselect.c (Fx_register_dnd_atom):
12321 Simplify previous changes by using xpalloc.
12323 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
12324 since either will do and ptrdiff_t is convenient with xpalloc.
12326 * charset.c (charset_table_size)
12327 (struct charset_sort_data.priority): Now ptrdiff_t.
12328 (charset_compare): Don't overflow if priorities differ greatly.
12329 (Fsort_charsets): Don't assume list length fits in int.
12330 Check for size-calculation overflow when allocating sort data.
12331 (syms_of_charset): Allocate an initial charset table that is
12332 just under 64 KiB, to avoid problems with glibc malloc and mmap.
12334 * cmds.c (internal_self_insert): Check for size-calculation overflow.
12336 * composite.h (struct composition.glyph_len): Now int, not unsigned.
12337 The actual value is always <= INT_MAX, and leaving it unsigned made
12338 overflow checking harder.
12340 * dispextern.h (struct glyph_matrix.rows_allocated)
12341 (struct face_cache.size): Now ptrdiff_t, for convenience in use
12342 with xpalloc. The values are still always <= INT_MAX.
12344 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
12346 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
12347 (SAFE_NALLOCA): New macro.
12349 * region-cache.c (struct boundary.pos, find_cache_boundary)
12350 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
12351 (set_cache_region, invalidate_region_cache)
12352 (revalidate_region_cache, know_region_cache, region_cache_forward)
12353 (region_cache_backward, pp_cache):
12354 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
12355 so that ptrdiff_t * can be passed to xpalloc.
12356 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
12357 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
12358 (pp_cache): Don't assume cache_len fits in int.
12359 * region-cache.h: Adjust extern decls to match.
12361 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
12362 EMACS_INT, since either will do, for xpalloc.
12364 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
12365 (xnmalloc, xnrealloc, xpalloc): New functions.
12367 * bidi.c (bidi_shelve_header_size): New constant.
12368 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
12369 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
12371 * bidi.c (bidi_cache_shrink):
12372 * buffer.c (overlays_at, overlays_in, record_overlay_string)
12374 Don't update size of array until after memory allocation succeeds,
12375 because xmalloc/xrealloc may not return.
12376 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
12377 now that we have proper integer overflow checking.
12378 (record_overlay_string, overlay_strings): Catch overflows when
12379 calculating size of overlay_str_buf.
12381 * callproc.c (Fcall_process): Check for size overflow when
12382 calculating size of args2.
12383 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
12384 Normally we prefer signed values, but sticking with ptrdiff_t would
12385 require adding more-complicated checks.
12387 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
12388 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
12389 Redo buffer-overflow calculations to avoid integer overflow.
12390 Add a FIXME comment where memory seems to be over-allocated.
12392 * character.c (Fstring): Check for size-calculation overflow.
12394 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
12395 unnecessary integer overflow. Check for size overflow.
12396 (encode_coding_object): Don't update size until xmalloc succeeds.
12398 * composite.c (get_composition_id): Check for overflow in glyph
12399 length calculations.
12401 Integer and memory overflow fixes for display code.
12402 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
12403 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
12404 (scrolling_window): Check for overflow in size calculations.
12405 (line_draw_cost, realloc_glyph_pool, add_row_entry):
12406 Don't assume glyph table len fits in int.

12408 (row_table_size): Now ptrdiff_t, not int.
12409 (scrolling_window): Avoid overflow in size calculations.
12410 Don't update size until allocation succeeds.
12411 * fns.c (concat): Check for overflow in size calculations.
12412 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
12413 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.

12416 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
12417 (get_doc_string): Check for size calculation overflow.
12418 Don't update size until allocation succeeds.
12419 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
12420 EMACS_INT, where ptrdiff_t will do.
12421 (Fsubstitute_command_keys): Check for string overflow.
12423 * editfns.c (set_time_zone_rule): Don't assume environment length
12425 (message_length): Now ptrdiff_t, not int.
12426 (Fmessage_box): Don't update size until allocation succeeds.
12427 Don't assume message length fits in int.
12428 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
12430 * emacs.c (main): Do not reallocate argv, since there is a null at
12431 the end that can be overwritten, and this way there's no need to
12432 worry about size-calculation overflow.
12433 (sort_args): Check for size-calculation overflow.
12435 * eval.c (init_eval_once, grow_specpdl): Don't update size until
12437 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
12439 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
12440 (x_set_scroll_bar_width, x_figure_window_size):
12441 Check for integer overflow.
12442 (x_set_alpha): Do not assume XINT fits in int.
12444 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
12445 This is for the members text_lines, text_cols, total_lines, total_cols,
12446 where the system imposes an 'int' limit.
12448 * fringe.c (Fdefine_fringe_bitmap):
12449 Don't update size until alloc works.
12451 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
12452 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
12454 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
12455 Check for size-calculation overflow.
12456 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
12457 do, as we prefer signed integers.
12458 (id_to_widget.max_size, id_to_widget.used)
12459 (xg_store_widget_in_map, xg_remove_widget_from_map)
12460 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
12461 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
12462 Use and return ptrdiff_t, not int.
12463 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
12464 * gtkutil.h: Change prototypes to match the above.
12466 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
12467 are duplicate now that they've been promoted to lisp.h.
12468 (x_allocate_bitmap_record, x_alloc_image_color)
12469 (make_image_cache, cache_image, xpm_load):
12470 Don't update size until alloc is done.

12475 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
12478 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
12479 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
12480 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
12481 Use ptrdiff_t, not int, to count maps.
12482 (read_char_minibuf_menu_prompt): Check for overflow in size
12483 calculations. Don't update size until allocation succeeds.
12484 Redo calculations to avoid overflow.
12485 * keyboard.h: Change prototypes to match the above.
12487 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
12489 (current_minor_maps): Check for size calculation overflow.
12490 * keymap.h: Change prototypes to match the above.
12492 * lread.c (read1, init_obarray): Don't update size until alloc done.
12494 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
12495 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.

12513 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
12514 for command line length. Do not attempt to address one before the
12515 beginning of an array, as that's not portable.
12517 * term.c (max_frame_lines): Remove; unused.
12518 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
12520 (encode_terminal_code, calculate_costs): Check for size
12521 calculation overflow.
12522 (encode_terminal_code): Use ptrdiff_t, not int, to record glyph

12524 done. Redo calculations to avoid overflow.
12525 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
12527 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of

12539 Use ptrdiff_t, not int, for sizes.
12540 (store_mode_line_noprop_char): Don't update size until alloc done.
12542 * xfaces.c (lface_id_to_name_size, Finternal_make_lisp_face):
12543 Use ptrdiff_t, not int, for sizes.
12544 (Finternal_make_lisp_face, cache_face):
12545 Check for size calculation overflow.
12546 (cache_face): Treat size calculation overflows as if they were
12547 memory exhaustion (the usual treatment), rather than aborting.
12549 * xfns.c (x_encode_text, x_set_name_internal)
12550 (Fx_change_window_property): Use ptrdiff_t, not int, to count
12551 sizes, since they can exceed INT_MAX in size. Check for size
12552 calculation overflow.
12554 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
12555 (xg_select): Check for size calculation overflow.
12556 Don't update size until alloc done.
12558 * xrdb.c (get_environ_db): Don't assume path length fits in int,
12559 as sprintf is limited to int lengths.
12561 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
12562 (X_LONG_MIN): New macros.
12563 Use them to make the following changes clearer.
12564 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
12565 This change doesn't affect the value now, but it may help remind
12566 future maintainers not to raise the value too much later.
12567 (SELECTION_QUANTUM): Remove, replacing with ...
12568 (selection_quantum): ... new function, which avoids overflow.
12570 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
12571 assumption that selection length fits in 'int'.
12572 (x_reply_selection_request, x_handle_selection_request)
12573 (x_get_window_property, receive_incremental_selection)
12574 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
12575 (lisp_data_to_selection_data, clean_local_selection_data):
12576 Use ptrdiff_t, not int, to record length of selection.
12577 (x_reply_selection_request, x_get_window_property)
12578 (receive_incremental_selection, x_property_data_to_lisp):
12579 Redo calculations to avoid overflow.
12580 (x_reply_selection_request): When sending hint, ceiling it at
12581 X_LONG_MAX rather than relying on wraparound overflow to send
12583 (x_get_window_property, receive_incremental_selection)
12584 (lisp_data_to_selection_data, x_property_data_to_lisp):
12585 Check for size-calculation overflow.
12586 (x_get_window_property, receive_incremental_selection)
12587 (lisp_data_to_selection_data, Fx_register_dnd_atom):
12588 Don't store size until memory allocation succeeds.
12589 (x_get_window_property): Plug memory leak on memory exhaustion.
12590 Don't double-block input; malloc is safe here. Don't assume 2**34
12591 - 4 fits in unsigned long. Add an xassert to check
12592 XGetWindowProperty overflow. Be more careful about overflow
12593 calculations, and distinguish size from memory overflow better.
12594 (receive_incremental_selection): When tracing, don't assume
12595 unsigned int is less than INT_MAX.
12596 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
12597 harmful) conversions of unsigned short to int.
12598 (lisp_data_to_selection_data): Don't assume that integers
12599 in the range -65535 through -1 fit in an X unsigned short.
12600 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
12601 result parameters unless successful. Rely on cons_to_unsigned
12602 to report problems with elements; the old code wasn't right anyway.
12603 (x_check_property_data): Check for int overflow; we cannot use
12604 a wider type due to X limits.
12605 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
12607 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
12609 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
12610 (x_term_init): Check for size calculation overflow.
12611 (x_color_cells): Don't store size until memory allocation succeeds.
12612 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
12613 Don't assume alloca size is less than MAX_ALLOCA.
12614 (x_term_init): Don't assume length fits in int (sprintf is limited
12617 Use ptrdiff_t for composition IDs.
12618 * character.c (lisp_string_width):
12619 * composite.c (composition_table_size, n_compositions)
12620 (get_composition_id, composition_gstring_from_id):
12621 * dispextern.h (struct glyph_string.cmp_id, struct composition_it.id):
12622 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING):
12623 * window.c (Frecenter):
12624 Use ptrdiff_t, not int, for composition IDs.
12625 * composite.c (get_composition_id): Check for integer overflow.
12626 * composite.h: Adjust prototypes to match the above changes.
12628 Use ptrdiff_t for hash table indexes.

12636 * image.c (xpm_get_color_table_h):
12637 * lisp.h (hash_lookup, hash_put):
12638 * minibuf.c (Ftest_completion):
12639 Use ptrdiff_t for hash table indexes, not int (which is too
12640 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
12641 32-bit --with-wide-int hosts).
12643 * charset.c (Fdefine_charset_internal): Check for integer overflow.
12644 Add a FIXME comment about memory leaks.
12645 (syms_of_charset): Don't assume xmalloc returns.
12647 Don't assume that stated character widths fit in int.
12648 * character.c (Fchar_width, c_string_width, lisp_string_width):
12649 * character.h (CHAR_WIDTH):
12650 * indent.c (MULTIBYTE_BYTES_WIDTH):
12651 Use sanitize_char_width to avoid undefined and/or bad behavior
12652 with outlandish widths.
12653 * character.h (sanitize_tab_width): Rename from sanitize_width,
12654 now that we have two such functions. All uses changed.
12655 (sanitize_char_width): New inline function.
12657 Don't assume that tab-width fits in int.
12658 * character.h (sanitize_width): New inline function.
12659 (SANE_TAB_WIDTH): New macro.
12660 (ASCII_CHAR_WIDTH): Use it.
12661 * indent.c (sane_tab_width): Remove. All uses replaced by
12662 SANE_TAB_WIDTH (current_buffer).
12663 * xdisp.c (init_iterator): Use SANE_TAB_WIDTH.
12665 * fileio.c: Integer overflow issues with file modes.
12666 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
12668 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
12669 Remove unreachable code.
12670 (read_hex, load_charset_map_from_file): Check for integer overflow.
12672 * xterm.c: Don't go over XClientMessageEvent limit.
12673 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
12674 (x_send_scroll_bar_event): Likewise. Check that the size does not
12675 exceed limits imposed by XClientMessageEvent, as well as the usual
12676 ptrdiff_t and size_t limits.
12678 * keyboard.c: Overflow, signedness and related fixes.
12679 (make_lispy_movement): Use same integer type in forward decl
12680 that is used in the definition.
12681 (read_key_sequence, keyremap_step):
12682 Change bufsize argument back to int, undoing my 2011-03-30 change.
12683 We prefer signed types, and int is wide enough here.
12684 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
12685 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
12686 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
12687 length, not size_t. Use ptrdiff_t for index, not int.
12688 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
12689 possibility of integer overflow.
12691 Overflow, signedness and related fixes for images.
12693 * dispextern.h (struct it.stack[0].u.image.image_id)
12694 (struct_it.image_id, struct image.id, struct image_cache.size)
12695 (struct image_cache.used, struct image_cache.ref_count):

12701 * xdisp.c (calc_pixel_width_or_height):
12702 * xfns.c (image_cache_refcount):
12703 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
12704 on typical 64-bit hosts.
12706 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
12707 (x_bitmap_pixmap, x_create_x_image_and_pixmap):

12710 when the callers expect that.
12711 (image_ascent): Redo ascent calculation to avoid int overflow.
12712 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
12713 (lookup_image): Remove unnecessary tests.
12714 (xbm_image_p): Locals are now of int, not EMACS_INT,
12715 since parse_image_check makes sure they fit into int.
12716 (png_load, gif_load, svg_load_image):
12717 Prefer int to unsigned where either will do.
12718 (tiff_handler): New function, combining the cores of the
12719 old tiff_error_handler and tiff_warning_handler.
12720 This function is rewritten to use vsnprintf and thereby avoid
12721 stack buffer overflows. It uses only the features of vsnprintf
12722 that are common to both POSIX and native Microsoft.
12723 (tiff_error_handler, tiff_warning_handler): Use it.
12724 (tiff_load, gif_load, imagemagick_load_image):
12725 Don't assume :index value fits in 'int'.
12726 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
12727 (imagemagick_load_image): Check that crop parameters fit into
12728 the integer types that MagickCropImage accepts. Don't assume
12729 Vimagemagick_render_type has a nonnegative value. Don't assume
12730 size_t fits in 'long'.
12731 (gs_load): Use printmax_t to print the widest integers possible.
12732 Check for integer overflow when computing image height and width.
12734 2011-08-26 Eli Zaretskii <eliz@gnu.org>
12736 * xdisp.c (redisplay_window): Don't force window start if point
12737 will be invisible in the resulting window. (Bug#9324)
12739 2011-08-25 Eli Zaretskii <eliz@gnu.org>
12741 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
12742 the display spec is of the form `(space ...)'.
12743 (handle_display_spec): Return the value returned by
12744 handle_single_display_spec, not just 1 or zero.
12745 (handle_single_display_spec): If the display spec is of the form
12746 `(space ...)', and specifies display in the text area, return 2
12748 (try_cursor_movement): Check for the need to scroll more
12749 accurately, and prefer exact match for point under bidi.
12750 Don't advance `row' beyond the last row of the window.
12752 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
12753 into disp_prop; all users changed.
12755 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
12756 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
12757 for the text covered by the display property.
12759 2011-08-25 Chong Yidong <cyd@stupidchicken.com>
12761 * buffer.c (Fbury_buffer_internal): Rename from Funrecord_buffer.

12763 (Frecord_buffer): Delete unused function.
12765 2011-08-24 Eli Zaretskii <eliz@gnu.org>
12767 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
12768 buffers, return left-to-right.
12769 (set_cursor_from_row): Consider candidate row a win if its glyph
12770 represents a newline and point is on that newline. Fixes cursor
12771 positioning on the newline at EOL of R2L text within L2R
12772 paragraph, and vice versa.
12773 (try_cursor_movement): Check continued rows, in addition to
12774 continuation rows. Fixes unwarranted scroll when point enters a
12775 continued line of R2L text within an L2R paragraph, or vice versa.
12776 (cursor_row_p): Consider the case of point being equal to
12777 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
12778 from the end of a short line to the beginning of a continued line
12779 of R2L text within L2R paragraph.
12780 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
12781 composed characters.
12783 * bidi.c (bidi_check_type): Use xassert.
12784 (bidi_cache_iterator_state): Update the disp_pos and disp_prop_p
12787 2011-08-23 Eli Zaretskii <eliz@gnu.org>

12792 2011-08-23 Chong Yidong <cyd@stupidchicken.com>
12794 * nsfont.m (ns_otf_to_script): Fix typo.
12796 2011-08-22 Kenichi Handa <handa@m17n.org>
12798 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
12799 extra slot even if the purpose is char-code-property-table.
12801 2011-08-23 Eli Zaretskii <eliz@gnu.org>
12803 * xdisp.c (redisplay_window): When computing centering_position,
12804 account for the height of the header line. (Bug#8874)
12806 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
12807 instead of CHAR_TO_BYTE. Fixes a crash when a completion
12808 candidate is selected by the mouse, and that candidate has a
12809 composed character under the mouse.
12811 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
12812 coordinates reported by pos-visible-in-window-p for a composed
12813 character in column zero.
12815 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
12817 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
12819 2011-08-22 Eli Zaretskii <eliz@gnu.org>
12821 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
12822 consider it a hit if to_charpos is anywhere in the range of the
12823 composed buffer positions.
12825 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
12827 * image.c (gif_load): Don't assume that each subimage has the same
12828 dimensions as the base image. Handle disposal method that is
12829 "undefined" by the gif spec (Bug#9335).
12831 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
12833 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
12834 (Fcondition_case): Document `debug' symbol in error handler.
12836 2011-08-19 Eli Zaretskii <eliz@gnu.org>
12838 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
12839 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
12840 from an Org mode buffer to a Speedbar frame.
12842 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
12843 a composition, take its buffer position from IT->cmp_it.charpos.
12844 Fixes cursor positioning at the beginning of a line that begins
12845 with a composed character.
12847 2011-08-18 Eli Zaretskii <eliz@gnu.org>
12849 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
12850 character bidirectional type, use STRONG_L instead. Fixes crashes
12851 in a buffer produced by `describe-categories'.
12853 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
12854 members before the level stack, so they would be saved and
12855 restored when copying iterator state. Fixes incorrect reordering
12856 around TABs covered by display properties.
12858 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
12860 * process.c (Fnetwork_interface_list): Correctly determine buffer size.
12862 2011-08-17 Chong Yidong <cyd@stupidchicken.com>
12864 * eval.c (internal_condition_case, internal_condition_case_1)
12865 (internal_condition_case_2, internal_condition_case_n):
12866 Remove unnecessary aborts (Bug#9081).
12868 2011-08-17 Eli Zaretskii <eliz@gnu.org>
12870 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
12871 has no `load' handler, try opening the file locally. (Bug#9311)
12873 2011-08-16 Ken Brown <kbrown@cornell.edu>
12875 * gmalloc.c: Expand comment.
12877 2011-08-16 Eli Zaretskii <eliz@gnu.org>
12879 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
12880 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
12882 2011-08-16 Ken Brown <kbrown@cornell.edu>
12884 Fix memory allocation problems in Cygwin build (Bug#9273).
12886 * unexcw.c ( __malloc_initialized): Declare external variable.
12887 (fixup_executable): Force the dumped emacs to reinitialize malloc.
12889 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
12891 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
12893 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
12894 in the static heap.
12895 [CYGWIN] (special_realloc): New function.
12896 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
12897 requests to realloc storage in the static heap.

12912 * chartab.c: Improve commentary for the uniprop_table API.
12914 * bidi.c (bidi_paragraph_init): Support zero value of
12915 bidi_ignore_explicit_marks_for_paragraph_level.
12916 (bidi_initialize): Use uniprop_table instead of including
12917 biditype.h and bidimirror.h.
12919 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
12920 coordinates of the iterator when restoring from ppos_it.
12923 2011-08-14 Kenichi Handa <handa@m17n.org>
12925 * process.c (create_process): Call setup_process_coding_systems
12926 after the pid of the process is set to -1 (Bug#8162).
12928 2011-08-14 Eli Zaretskii <eliz@gnu.org>
12930 * xdisp.c (move_it_in_display_line_to): Don't invoke
12931 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
12932 ppos_it. Fixes vertical cursor motion when line beginning is
12933 covered by an image. (Bug#9296)
12935 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
12937 * nsterm.h (ns_run_ascript): Declare.
12938 (NSAPP_DATA2_RUNASSCRIPT): Define.
12940 * nsfns.m (as_script, as_result, as_status): New static variables.
12941 (ns_run_ascript): New function.
12942 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
12943 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
12944 the event loop. Get status from as_status (Bug#7276).
12946 * nsterm.m (sendEvent): If event is NSApplicationDefined and
12947 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
12948 the event loop (Bug#7276).
12950 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
12952 * gnutls.c (QCgnutls_bootprop_priority)
12953 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
12954 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
12955 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)

12957 (QCgnutls_bootprop_verify_hostname_error)
12958 (QCgnutls_bootprop_callbacks_verify): Rename from
12959 Qgnutls_bootprop_..., all uses changed.
12961 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
12964 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
12966 * xfaces.c (Qframe_set_background_mode): Now static.
12967 * dispextern.h (Qframe_set_background_mode): Remove decl.
12969 * process.c (Fnetwork_interface_info): Declare local only if needed.
12971 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
12973 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
12974 (Fnetwork_interface_list): Allocate in increments of bytes instead
12975 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
12976 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
12978 (struct ifflag_def): notrailers is smart on OSX.
12979 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
12980 Get hardware address with getifaddrs if available.
12982 2011-08-12 Eli Zaretskii <eliz@gnu.org>
12984 * xdisp.c (iterate_out_of_display_property): xassert that
12985 IT->position is set to within IT->object's boundaries. Break from
12986 the loop as soon as EOB is reached; avoids infloops in redisplay
12987 when IT->position is set up wrongly due to some bug.
12988 Set IT->current to match the bidi iterator unconditionally.
12989 (push_display_prop): Allow GET_FROM_STRING as IT->method on
12990 entry. Force push_it to save on the stack the current
12991 buffer/string position, to be restored by pop_it. Fix flags in
12992 the iterator structure wrt the object coming from a display
12993 property, as `line-prefix' and `wrap-prefix' are not ``replacing''

13011 no-display-properties-and-no-overlays under bidi display.
13012 Set disp_pos in the bidi iterator to avoid searches for display
13013 properties and overlays.
13015 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
13017 * editfns.c (Fset_time_zone_rule): Document relationship with the

13023 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
13025 * composite.c (autocmp_chars): Don't reset point. That is done by
13026 restore_point_unwind (Bug#5984).
13028 2011-08-07 Juri Linkov <juri@jurta.org>
13030 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
13031 to show the arg `TIME' instead of `TIMEVAL'.
13033 2011-08-06 Eli Zaretskii <eliz@gnu.org>
13035 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
13036 display property strides EOL and includes a newline, as in
13037 longlines-mode. (Bug#9254)
13038 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
13039 word-wrap under bidirectional display. (Bug#9224)
13041 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
13042 is non-zero, even if the data buffer is NULL. Fixes a crash in
13043 vertical-motion with longlines-mode. (Bug#9254)
13045 2011-08-05 Eli Zaretskii <eliz@gnu.org>
13047 * bidi.c <bidi_cache_total_alloc>: Now static.
13048 (bidi_initialize): Initialize bidi_cache_total_alloc.
13050 * xdisp.c (display_line): Release buffer allocated for shelved bidi
13053 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
13054 amount allocated this far in `bidi_cache_total_alloc'.
13055 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
13056 non-zero, only free the data buffer without restoring the cache
13057 contents. All callers changed.
13059 * dispextern.h (bidi_unshelve_cache): Update prototype.
13061 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
13062 (move_it_in_display_line, move_it_to)
13063 (move_it_vertically_backward, move_it_by_lines): Replace the call
13064 to xfree to an equivalent call to bidi_unshelve_cache.
13065 (move_it_in_display_line_to): Fix logic of returning
13066 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
13068 2011-08-05 Eli Zaretskii <eliz@gnu.org>
13070 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
13071 came from a string character with a `cursor' property. (Bug#9229)
13073 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
13075 * Makefile.in (LIB_PTHREAD): New variable.
13076 (LIBES): Add LIB_PTHREAD (Bug#9216).
13078 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
13079 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
13081 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
13083 * regex.c (re_iswctype): Remove some redundant boolean conversions.
13085 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
13087 * xterm.c (x_find_topmost_parent): New function.
13088 (x_set_frame_alpha): Find topmost parent window with
13089 x_find_topmost_parent and set the property there also (bug#9181).
13090 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
13092 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
13094 * callproc.c (Fcall_process): Avoid vfork clobbering
13095 the local vars buffer, coding_systems, current_dir.
13097 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
13099 * keymap.c (Fmake_composed_keymap): Move to subr.el.
13101 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
13103 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
13104 so that it is not optimized away.
13106 * xdisp.c (compute_display_string_pos): Remove unused local.
13108 2011-08-02 Eli Zaretskii <eliz@gnu.org>
13110 Fix slow cursor motion and scrolling in large buffers with
13111 selective display, like Org Mode buffers. (Bug#9218)
13113 * dispextern.h (struct bidi_it): New member disp_prop_p.
13115 * xdisp.c: Remove one-slot cache of display string positions.
13116 (compute_display_string_pos): Accept an additional argument
13117 DISP_PROP_P; callers changed. Scan at most 5K characters forward
13118 for a display string or property. If found, set DISP_PROP_P
13121 * bidi.c (bidi_fetch_char): Accept an additional argument
13122 DISP_PROP_P, and pass it to compute_display_string_pos.
13123 Only handle text covered by a display string if DISP_PROP_P is returned
13124 non-zero. All callers of bidi_fetch_char changed.
13126 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
13128 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
13130 2010-12-03 Don March <don@ohspite.net>
13132 * keymap.c (Fdefine_key): Fix non-prefix key error message when
13133 last character M-[char] is translated to ESC [char] (bug#7541).
13135 2011-08-02 Kenichi Handa <handa@m17n.org>
13137 * lisp.h (uniprop_table): Extern it.
13139 * chartab.c (uniprop_table): Make it non-static.
13141 2011-08-01 Eli Zaretskii <eliz@gnu.org>
13143 * xdisp.c (forward_to_next_line_start): Accept additional argument
13144 BIDI_IT_PREV, and store into it the state of the bidi iterator had
13146 (reseat_at_next_visible_line_start): Use the bidi iterator state
13147 returned by forward_to_next_line_start to restore the state of
13148 it->bidi_it after backing up to previous newline. (Bug#9212)
13150 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
13152 * regex.c (re_comp): Protoize.
13153 (re_exec): Fix return type.
13154 (regexec): Fix type of `ret'. (Bug#9203)
13156 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13158 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
13159 This is needed if max-image-size is a floating-point number.
13161 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
13163 * print.c (print_object): Print empty symbol as ##.
13165 * lread.c (read1): Read ## as empty symbol.
13167 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
13169 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
13170 setting frame foreground color (Bug#9175).
13171 (x_set_background_color): Likewise.
13173 * nsmenu.m (-setText): Size tooltip dimensions precisely to
13174 contents (Bug#9176).
13175 (EmacsTooltip -init): Remove bezels and add shadows to
13178 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
13179 or scroll bar (Bug#8470).
13181 * nsfont.m (nsfont_open): Remove assignment to voffset and
13182 unnecessary vars hshink, expand, hd, full_height, min_height.
13183 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
13185 * nsterm.h (nsfont_info): Remove voffset field.
13187 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
13189 Implement strike-through and overline on NextStep (Bug#8863).
13191 * nsfont.m (nsfont_open): Use underline position provided by font,
13192 instead of hard-coded value of 2.
13193 (nsfont_draw): Call ns_draw_text_decoration instead.
13195 * nsterm.h: Add declaration for ns_draw_text_decoration.
13197 * nsterm.m (ns_draw_text_decoration): New function for drawing
13198 underline, overline, and strike-through.
13199 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
13200 ns_draw_text_decoration. Change treatment of cursor drawing to
13201 accommodate underlining, etc.
13203 2011-07-28 Eli Zaretskii <eliz@gnu.org>
13205 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
13208 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13210 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
13211 Without this fix, if a signal arrives just after memory fills up,
13212 'malloc' might be invoked reentrantly.
13214 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
13215 In other words, assume that every image size is allowed, on non-X
13216 hosts. This assumption is probably wrong, but it lets Emacs compile.
13218 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
13220 * regex.c (re_iswctype): Convert return values to boolean.
13222 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
13224 * xdisp.c (compute_display_string_pos): Don't use cached display
13225 string position if the buffer had its restriction changed.
13228 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13230 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
13232 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13234 Integer signedness and overflow and related fixes. (Bug#9079)
13236 * bidi.c: Integer size and overflow fixes.
13237 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
13238 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
13239 (bidi_cache_find_level_change, bidi_cache_ensure_space)
13240 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
13241 (bidi_find_other_level_edge):
13242 Use ptrdiff_t instead of EMACS_INT where either will do.
13243 This works better on 32-bit hosts configured --with-wide-int.
13244 (bidi_cache_ensure_space): Check for size-calculation overflow.
13245 Use % rather than repeated addition, for better worst-case speed.
13246 Don't set bidi_cache_size until after xrealloc returns, because it
13248 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
13249 (bidi_cache_ensure_space): Also check that the bidi cache size
13250 does not exceed that of the largest Lisp string or buffer. See Eli
13251 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
13253 * alloc.c (__malloc_size_t): Remove.
13254 All uses replaced by size_t. See Andreas Schwab's note
13255 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
13257 * image.c: Improve checking for integer overflow.
13258 (check_image_size): Assume that f is nonnull, since
13259 it is always nonnull in practice. This is one less thing to
13260 worry about when checking for integer overflow later.
13261 (x_check_image_size): New function, which checks for integer
13262 overflow issues inside X.
13263 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
13264 This removes the need for a memory_full check.
13265 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
13266 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
13267 (xbm_read_bitmap_data): Change locals back to 'int', since
13268 their values must fit in 'int'.
13269 (xpm_load_image, png_load, tiff_load):
13270 Invoke x_create_x_image_and_pixmap earlier,
13271 to avoid much needless work if the image is too large.
13272 (tiff_load): Treat overly large images as if
13273 x_create_x_image_and_pixmap failed, not as malloc failures.
13274 (gs_load): Use x_check_image_size.
13276 * gtkutil.c: Omit integer casts.
13277 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
13278 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
13280 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
13282 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
13283 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
13284 would wrongly return t on a 64-bit host.
13286 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
13287 The plain *_OVERFLOW macros run afoul of GCC bug 49705
13288 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
13289 and therefore cause GCC to emit a bogus diagnostic in some cases.
13291 * image.c: Integer signedness and overflow and related fixes.
13292 This is not an exhaustive set of fixes, but it's time to
13293 record what I've got.
13294 (lookup_pixel_color, check_image_size): Remove redundant decls.
13295 (check_image_size): Don't assume that arbitrary EMACS_INT values
13296 fit in 'int', or that arbitrary 'double' values fit in 'int'.
13297 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
13298 (tiff_load, imagemagick_load_image):
13299 Check for overflow in size calculations.
13300 (x_create_x_image_and_pixmap): Remove unnecessary test for
13301 xmalloc returning NULL; that can't happen.
13302 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
13303 (xpm_color_bucket): Use better integer hashing function.
13304 (xpm_cache_color): Don't possibly over-allocate memory.
13305 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
13306 (gif_memory_source):
13307 Use ptrdiff_t, not int or size_t, to record sizes.
13308 (png_load): Don't assume values greater than 2**31 fit in 'int'.
13309 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
13310 either works, as we prefer signed integers.
13311 (tiff_read_from_memory, tiff_write_from_memory):
13312 Return tsize_t, not size_t, since that's what the TIFF API wants.
13313 (tiff_read_from_memory): Don't fail simply because the read would
13314 go past EOF; instead, return a short read.
13315 (tiff_load): Omit no-longer-needed casts.
13316 (Fimagemagick_types): Don't assume size fits into 'int'.
13318 Improve hashing quality when configured --with-wide-int.
13319 * fns.c (hash_string): New function, taken from sxhash_string.
13320 Do not discard information about ASCII character case; this
13321 discarding is no longer needed.
13322 (sxhash-string): Use it. Change sig to match it. Caller changed.
13323 * lisp.h: Declare it.
13324 * lread.c (hash_string): Remove, since we now use fns.c's version.
13325 The fns.c version returns a wider integer if --with-wide-int is
13326 specified, so this should help the quality of the hashing a bit.
13328 * emacs.c: Integer overflow minor fix.
13329 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
13330 Define only if GNU_LINUX.
13331 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
13333 * dispnew.c: Integer signedness and overflow fixes.
13334 Remove unnecessary forward decls, that were a maintenance hassle.
13335 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
13337 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
13338 (scrolling_window): Use ptrdiff_t, not int, for byte count.
13339 (prepare_desired_row, line_draw_cost):
13340 Use int, not unsigned, where either works.
13341 (save_current_matrix, restore_current_matrix):
13342 Use ptrdiff_t, not size_t, where either works.
13343 (init_display): Check for overflow more accurately, and without
13344 relying on undefined behavior.
13346 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
13347 Remove, replacing with the new symbols in lisp.h. All uses changed.
13348 * fileio.c (make_temp_name):
13349 * filelock.c (lock_file_1, lock_file):
13350 * xdisp.c (message_dolog):
13351 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
13352 Use pMd etc. instead.
13353 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
13354 replacing the pWIDE etc. symbols removed from editfns.c.
13356 * keyboard.h (num_input_events): Now uintmax_t.
13357 This is (very slightly) less likely to mess up due to wraparound.
13360 * buffer.c: Integer signedness fixes.
13361 (alloc_buffer_text, enlarge_buffer_text):
13362 Use ptrdiff_t rather than size_t when either will do, as we prefer
13365 * alloc.c: Integer signedness and overflow fixes.
13366 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
13367 (__malloc_size_t): Default to size_t, not to int.
13368 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
13369 (Fgarbage_collect, mark_object_loop_halt, mark_object):
13370 Prefer ptrdiff_t to size_t when either would do, as we prefer
13372 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
13373 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
13374 Now const. Initialize with values that are in range even if char
13376 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
13377 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
13378 These functions do the right thing with sizes > 2**32.
13379 (check_depth): Now ptrdiff_t, not int.
13380 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
13381 Adjust to new way of storing sizes. Check for size overflow bugs
13383 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
13384 slightly wrong anyway, as it missed one instance of
13385 XMALLOC_OVERRUN_CHECK_OVERHEAD.
13386 (refill_memory_reserve): Omit needless cast to size_t.
13387 (mark_object_loop_halt): Mark as externally visible.
13389 * xselect.c: Integer signedness and overflow fixes.
13390 (Fx_register_dnd_atom, x_handle_dnd_message):
13391 Use ptrdiff_t, not size_t, since we prefer signed.
13392 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
13393 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
13394 x_dnd_atoms_size and x_dnd_atoms_length.
13396 * doprnt.c: Prefer signed to unsigned when either works.
13398 * doprnt.c (doprnt):
13400 * xdisp.c (vmessage):
13401 Use ptrdiff_t, not size_t, when using or implementing doprnt,
13402 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
13403 prefer signed arithmetic to avoid comparison confusion.
13404 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
13405 but is a bit tricky.
13407 Assume freestanding C89 headers, string.h, stdlib.h.
13408 * data.c, doprnt.c, floatfns.c, print.c:
13409 Include float.h unconditionally.
13410 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
13411 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
13412 * regex.c: Likewise for stddef.h, string.h.
13413 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
13414 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
13415 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
13416 (STDC_HEADERS): Remove obsolete defines.
13417 * sysdep.c: Include limits.h unconditionally.
13419 Assume support for memcmp, memcpy, memmove, memset.
13420 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
13421 * regex.c (memcmp, memcpy):
13422 Remove; we assume C89 now.
13424 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
13425 (__malloc_safe_bcopy): Remove; no longer needed.
13427 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
13428 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
13429 well either way, and we prefer signed to unsigned.
13431 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
13433 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
13434 closes the connection while we're reading (bug#9182).
13436 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
13438 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
13439 are specified (Bug#9168).
13441 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
13443 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
13444 Found by GCC static checking and --with-wide-int on a 32-bit host.
13446 2011-07-25 Eli Zaretskii <eliz@gnu.org>
13448 * xdisp.c (compute_display_string_pos): Fix logic of caching
13449 previous display string position. Initialize cached_prev_pos to
13450 -1. Fixes slow-down at the beginning of a buffer.
13452 2011-07-24 Eli Zaretskii <eliz@gnu.org>
13454 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
13455 for attrs[LFACE_FONTSET_INDEX].
13457 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
13459 * xml.c (parse_region): Remove unused local
13460 that was recently introduced.
13462 2011-07-23 Eli Zaretskii <eliz@gnu.org>
13464 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
13465 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
13467 * xdisp.c (move_it_in_display_line_to): Record the best matching
13468 position for TO_CHARPOS while scanning the line, and restore it on
13469 exit if none of the characters scanned was an exact match.
13470 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
13471 when exact match is impossible due to invisible text, and the
13472 lines are truncated.
13474 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
13476 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
13479 2011-07-22 Eli Zaretskii <eliz@gnu.org>
13481 Fix a significant slow-down of cursor motion with C-n, C-p,
13482 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
13483 auto-repeat under bidi redisplay in fontified buffers.
13484 * xdisp.c (compute_stop_pos_backwards): New function.
13485 (next_element_from_buffer): Call compute_stop_pos_backwards to
13486 find a suitable prev_stop when we find ourselves before
13488 (reseat): Don't look for prev_stop, as that could mean a very long
13490 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
13491 <cached_disp_overlay_modiff>: Cache for last found display string
13493 (compute_display_string_pos): Return the cached position if asked
13494 about the same buffer in the same area of character positions, and
13495 the buffer wasn't changed since the time the display string
13496 position was cached.
13498 2011-07-22 Eli Zaretskii <eliz@gnu.org>
13500 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
13501 is an integer, which is important for empty lines. (Bug#9149)
13503 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
13505 * frame.c (Fmodify_frame_parameters): In tty case, update the
13506 default face if necessary (Bug#4238).
13508 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
13510 * editfns.c (Fstring_to_char): No need to explain what a character
13511 is in the docstring (Bug#6576).
13513 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
13515 * xml.c (parse_region): Make sure we always return a tree.
13517 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
13519 * xml.c (parse_region): If a document contains only comments,
13522 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
13524 * xml.c (make_dom): Return comments, too.
13526 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
13529 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
13530 and the surrounding thread.
13531 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
13532 rather than fgets, and retry after EINTR. Otherwise, 'emacs
13533 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
13535 * s/openbsd.h (BROKEN_SIGIO): Define.
13536 * unexelf.c (unexec) [__OpenBSD__]:
13537 Don't update the .mdebug section of the Alpha COFF symbol table.
13539 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
13541 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
13544 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
13546 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
13547 This fixes some race conditions on the permissions of any newly
13550 * alloc.c (valid_pointer_p): Use pipe, not open.
13551 This fixes some permissions issues when debugging.
13553 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
13554 If fchown fails to set both uid and gid, try to set just gid,
13555 as that is sometimes allowed. Adjust the file's mode to eliminate
13556 setuid or setgid bits that are inappropriate if fchown fails.
13558 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
13560 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ

13572 symbol character follows.
13574 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
13576 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
13577 This works around a problem with the previous change to Fcopy_file.
13578 Recent glibc declares fchown with __attribute__((warn_unused_result)),
13579 and without this change, GCC might complain about discarding
13580 fchown's return value.
13582 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
13584 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
13586 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
13588 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
13590 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
13592 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
13593 it's used from the C level.
13595 * process.c: Use the same condition for POLL_FOR_INPUT in both
13596 keyboard.c and process.c (bug#1858).
13598 2011-07-09 Lawrence Mitchell <wence@gmx.li>
13600 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
13601 (Fgnutls_boot): Use it.
13603 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
13605 * doc.c (Fsubstitute_command_keys): Revert last change.
13607 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
13609 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
13610 quotes the next character, and doesn't affect other longer
13611 sequences (bug#8935).
13613 * lread.c (syms_of_lread): Clarify that is isn't only
13614 `eval-buffer' and `eval-defun' that's affected by
13615 `lexical-binding' (bug#8460).
13617 2011-07-15 Eli Zaretskii <eliz@gnu.org>
13619 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
13620 bidi redisplay when a line includes both an image and is truncated.
13622 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
13624 Fix minor problems found by static checking.
13625 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
13626 (elsz): Now a signed constant, not a size_t var. We prefer signed
13627 types to unsigned, to avoid integer comparison confusion. Without
13628 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
13629 "cannot optimize loop, the loop counter may overflow", a symptom
13631 * indent.c (Fvertical_motion): Mark locals as initialized.
13632 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
13634 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>

13657 buffer position was specified. Initialize paragraph_embedding to
13659 (reseat_to_string): Initialize the bidi iterator.
13660 (display_string): If we need to ignore text properties of
13661 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
13662 original value of -1 will not work with bidi.)
13663 (compute_display_string_pos): First arg is now struct
13664 `text_pos *'; all callers changed. Support display properties on
13666 (compute_display_string_end): Support display properties on Lisp
13668 (init_iterator, reseat_1, reseat_to_string): Initialize the
13669 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
13670 when iterating on a string not from display properties).
13671 (compute_display_string_pos, compute_display_string_end):
13672 Fix calculation of the object to scan. Fixes an error when using
13674 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
13675 base_level_stop; instead, set base_level_stop to BEGV.
13676 Fixes crashes in vertical-motion.
13677 (next_element_from_buffer): Improve commentary for when
13678 the iterator is before prev_stop.
13679 (init_iterator): Initialize bidi_p from the default value of
13680 bidi-display-reordering, not from buffer-local value. Use the
13681 buffer-local value only if initializing for buffer iteration.

13702 parts of next_element_from_buffer, next_element_from_string, and
13703 next_element_from_c_string.

13705 (display_menu_bar): Force left-to-right direction. Add a FIXME
13706 comment for making that be controlled by a user option.

13715 (get_overlay_strings_1, push_display_prop): Set up the bidi
13716 iterator for displaying display or overlay strings.
13717 (forward_to_next_line_start): Don't use the shortcut if
13719 (back_to_previous_visible_line_start): If handle_display_prop
13720 pushed the iterator stack, restore the internal state of the bidi
13721 iterator by calling bidi_pop_it same number of times.
13722 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
13723 and we are bidi-iterating, don't decrement the iterator position;
13724 instead, set the first_elt flag in the bidi iterator, to produce
13726 (reseat_1): Remove redundant setting of string_from_display_prop_p.
13727 (push_display_prop): xassert that we are iterating a buffer.
13728 (push_it, pop_it): Save and restore paragraph_embedding member.
13729 (handle_single_display_spec, next_overlay_string)
13730 (get_overlay_strings_1, reseat_1, reseat_to_string)
13731 (push_display_prop): Set up the `unibyte' member of bidi_it.string
13732 correctly. Don't assume unibyte strings are not bidi-reordered.
13733 (compute_display_string_pos)
13734 (compute_display_string_end): Fix handling the case of C string.

13741 property. Fix a typo in popping stretch info. Add an assertion
13742 for verifying that the iterator position is in sync with the bidi
13744 (handle_single_display_spec, get_overlay_strings_1)

13769 displayed in margins. (Bug#8133) (Bug#8867)
13770 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past

13798 changed to -1 and -2, respectively.
13799 (bidi_char_at_pos): New function.
13800 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):

13886 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
13888 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
13889 The old code sometimes used this field without initializing it.
13891 * alloc.c (gc_sweep): Don't read past end of array.
13892 In theory, the old code could also have corrupted Emacs internals,
13893 though it'd be very unlikely.

14160 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):

14198 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
14199 subseconds part to the entropy, as that's a bit more random.
14200 Prefer signed to unsigned, since the signedness doesn't matter and
14201 in general we prefer signed. When given a limit, use a
14202 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
14203 latter isn't right if USE_2_TAGS_FOR_INTS.
14204 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
14205 not 0..VALMASK. Don't discard "excess" bits that random () returns.

14217 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
14218 This is more efficient than Ffile_directory_p and avoids a minor race.

14222 * buffer.c (Foverlay_put): Say what the return value is
14225 * fileio.c (barf_or_query_if_file_exists): Check first if the file

14229 error be more correct.
14231 * fns.c (Frequire): Remove the mention of the .gz files, since

14248 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
14249 Also (re)move comments that are misplaced or no longer relevant.

14278 * lread.c (syms_of_lread): Mention single symbols defined by

14335 with value as argument.
14336 (init_gsettings): Check that GSETTINGS_SCHEMA exists before calling
14337 g_settings_new (Bug#8967). Do not create gsettings_obj.

14350 * eval.c (struct backtrace): Simplify and port the data structure.
14351 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
14352 signed bit field, as this assumption is not portable and it makes
14353 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
14354 "char debug_on_exit : 1" as this is not portable either; instead,
14355 use the portable "unsigned int debug_on_exit : 1". Remove unused
14356 member evalargs. Remove obsolete comments about cc bombing out.
14358 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

14426 (emacs_fixed_new): Set priv->f to argument.
14427 (emacs_fixed_get_preferred_width)
14428 (emacs_fixed_get_preferred_height): Use min_width/height from
14429 frames size_hint to set minimum and natural (Bug#8919).
14430 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
14431 and use min_width/height from frames size_hint to set
14432 min_width/height (Bug#8919).

14452 Use gnulib's dup2 module instead of rolling our own.
14453 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.

14520 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
14522 Integer and buffer overflow fixes (Bug#8873).
14524 * print.c (printchar, strout): Check for string overflow.
14525 (PRINTPREPARE, printchar, strout):
14526 Don't set size unless allocation succeeds.
14528 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
14529 for sizes. Check for string overflow more accurately.
14530 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
14532 * macros.c: Integer and buffer overflow fixes.
14533 * keyboard.h (struct keyboard.kbd_macro_bufsize):
14534 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

14538 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
14540 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
14542 * lread.c: Integer overflow fixes.
14543 (read_integer): Radix is now EMACS_INT, not int,
14544 to improve quality of diagnostics for out-of-range radices.
14545 Calculate buffer size correctly for out-of-range radices.
14546 (read1): Check for integer overflow in radices, and in
14547 read-circle numbers.
14548 (read_escape): Avoid int overflow.
14549 (Fload, openp, read_buffer_size, read1)
14550 (substitute_object_recurse, read_vector, read_list, map_obarray):
14551 Use ptrdiff_t, not int, for sizes.

14566 2011-06-22 Leo Liu <sdl.web@gmail.com>
14568 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
14569 Move to minibuffer.el.
14571 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
14573 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
14574 The following patches are for when GLYPH_DEBUG && !XASSERT.
14575 * dispextern.h (trace_redisplay_p, dump_glyph_string):
14576 * dispnew.c (flush_stdout):
14577 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
14578 Mark as externally visible.
14579 * dispnew.c (check_window_matrix_pointers): Now static.
14580 * dispnew.c (window_to_frame_vpos):
14581 * xfns.c (unwind_create_frame):
14582 * xterm.c (x_check_font): Remove unused local.
14583 * scroll.c (CHECK_BOUNDS):
14584 * xfaces.c (cache_fache): Rename local to avoid shadowing.
14585 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
14586 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
14587 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
14588 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
14590 (debug_method_add): Use va_list and vsprintf rather than relying
14591 on undefined behavior with wrong number of arguments.
14592 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
14593 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
14594 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
14595 since we're not interested in debugging glyphs with old libraries.
14596 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
14597 GCC 4.6.0's static checking.
14599 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
14601 Integer overflow and signedness fixes (Bug#8873).

14610 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
14611 (x_create_bitmap_from_xpm_data):
14612 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
14613 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
14615 * xfaces.c (load_pixmap):
14616 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
14617 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
14618 (.bitmaps_last, struct x_output.icon_bitmap):
14619 Use ptrdiff_t, not int, for bitmap indexes.
14620 (x_allocate_bitmap_record): Check for size overflow.
14621 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
14623 Use ptrdiff_t, not int, for overlay counts.
14624 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
14625 * editfns.c (overlays_around, get_pos_property):
14626 * textprop.c (get_char_property_and_overlay):
14627 * xdisp.c (next_overlay_change, note_mouse_highlight):
14628 * xfaces.c (face_at_buffer_position):
14629 * buffer.c (OVERLAY_COUNT_MAX): New macro.
14630 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
14631 (Fnext_overlay_change, Fprevious_overlay_change)
14632 (mouse_face_overlay_overlaps, Foverlays_in):
14633 Use ptrdiff_t, not int, for sizes.
14634 (overlays_at, overlays_in): Check for size-calculation overflow.
14636 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
14638 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
14639 (x_session_initialize): Do not assume string length fits in int.
14641 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
14642 This is unlikely, but can occur if DPI is outlandish.
14644 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
14645 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
14647 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
14648 * xrdb.c (magic_file_p, search_magic_path):
14649 Omit last arg SUFFIX; it was always 0. All callers changed.
14650 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
14652 * xfont.c (xfont_match): Avoid need for strlen.
14654 * xfns.c: Don't assume strlen fits in int.

14657 * xdisp.c (message_log_check_duplicate): Return intmax_t,
14658 not unsigned long, as we prefer signed integers. All callers changed.
14659 Detect integer overflow in repeat count.
14660 (message_dolog): Don't assume print length fits in 39 bytes.
14661 (display_mode_element): Don't assume strlen fits in int.
14663 * termcap.c: Don't assume sizes fit in int and never overflow.
14664 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
14665 (gobble_line): Check for size-calculation overflow.
14667 * minibuf.c (Fread_buffer):
14668 * lread.c (intern, intern_c_string):
14669 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

14682 * filelock.c: Fix some buffer overrun and integer overflow issues.
14683 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
14684 Reformulate so as not to need the command string.
14685 Invoke gzip -cd rather than gunzip, as it's more portable.
14686 (lock_info_type, lock_file_1, lock_file):
14687 Don't assume pid_t and time_t fit in unsigned long.
14688 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
14689 (current_lock_owner): Prefer signed type for sizes.
14690 Use memcpy, not strncpy, where memcpy is what is really wanted.
14691 Don't assume (via atoi) that time_t and pid_t fit in int.
14692 Check for time_t and/or pid_t out of range, e.g., via a network share.
14693 Don't alloca where an auto var works fine.
14695 * fileio.c: Fix some integer overflow issues.
14696 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
14697 Don't assume string length fits in int.
14698 (directory_file_name): Don't assume string length fits in long.
14699 (make_temp_name): Don't assume pid fits in int, or that its print
14700 length is less than 20.
14702 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
14704 * coding.c (make_subsidiaries): Don't assume string length fits in int.
14706 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
14708 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.

14711 * emacs.c: Don't assume string length fits in 'int'.
14712 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
14713 (main): Don't invoke strlen when not needed.

14718 * callproc.c (getenv_internal_1, getenv_internal)
14719 (Fgetenv_internal):
14720 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
14722 * lread.c (invalid_syntax): Omit length argument.
14723 All uses changed. This doesn't fix a bug, but it simplifies the
14724 code away from its former Hollerith-constant appearance, and it's
14725 one less 'int' to worry about when looking at integer-overflow issues.
14726 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
14728 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
14729 This didn't break anything, but it didn't help either.
14730 It's confusing to put a bogus integer in a place where the actual
14731 value does not matter.
14732 (LIST_END_P): Remove unused macro and its bogus comment.
14733 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
14735 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
14736 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
14738 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
14739 We prefer signed types, and the value cannot exceed the EMACS_INT
14740 range anyway (because otherwise the length would not be representable).
14741 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
14742 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
14743 This avoids a GCC warning when WIDE_EMACS_INT.
14745 * indent.c (sane_tab_width): New function.
14746 (current_column, scan_for_column, Findent_to, position_indentation)
14747 (compute_motion): Use it. This is just for clarity.
14748 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
14750 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
14752 * lisp.h (lint_assume): New macro.
14753 * composite.c (composition_gstring_put_cache):
14754 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
14756 * editfns.c, insdel.c:
14757 Omit unnecessary forward decls, to simplify future changes.
14759 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
14761 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
14763 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
14764 Use much-faster test for byte-length change.
14765 Don't assume string byte-length fits in 'int'.
14766 Check that character arg fits in 'int'.
14767 (mapcar1): Declare byte as byte, for clarity.
14769 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
14771 * fns.c (concat): Catch string overflow earlier.
14772 Do not rely on integer wraparound.
14774 * dispextern.h (struct it.overlay_strings_charpos)
14775 (struct it.selective): Now EMACS_INT, not int.
14776 * xdisp.c (forward_to_next_line_start)
14777 (back_to_previous_visible_line_start)
14778 (reseat_at_next_visible_line_start, next_element_from_buffer):
14779 Don't arbitrarily truncate the value of 'selective' to int.
14781 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
14783 * composite.c: Don't truncate sizes to 'int'.
14784 (composition_gstring_p, composition_reseat_it)
14785 (composition_adjust_point): Use EMACS_INT, not int.
14786 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
14787 not EMACS_UINT, for indexes.
14789 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
14791 * buffer.c: Include <verify.h>.
14792 (struct sortvec.priority, struct sortstr.priority):
14793 Now EMACS_INT, not int.
14794 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
14795 (struct sortstr.size, record_overlay_string)
14796 (struct sortstrlist.size, struct sortlist.used):
14797 Don't truncate size to int.
14798 (record_overlay_string): Check for size-calculation overflow.
14799 (init_buffer_once): Check at compile-time, not run-time.
14801 2011-06-22 Jim Meyering <meyering@redhat.com>
14803 Don't leak an XBM-image-sized buffer
14804 * image.c (xbm_load): Free the image buffer after using it.
14806 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
14809 * composite.c (find_automatic_composition): Omit needless 'return 0;'
14810 that Sun C diagnosed.
14811 * fns.c (secure_hash): Fix pointer signedness issue.
14812 * intervals.c (static_offset_intervals): New function.
14813 (offset_intervals): Use it.
14815 2011-06-21 Leo Liu <sdl.web@gmail.com>
14818 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
14821 * fns.c (secure_hash): Rename from crypto_hash_function and change
14822 the first arg to accept symbols.
14823 (Fsecure_hash): New primitive.
14824 (syms_of_fns): New symbols.
14826 2011-06-20 Deniz Dogan <deniz@dogan.se>
14828 * process.c (Fset_process_buffer): Clarify return value in
14831 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
14833 * dispnew.c (add_window_display_history): Use BVAR.
14835 * xdisp.c (debug_method_add): Use BVAR.
14836 (check_window_end, dump_glyph_matrix, dump_glyph)
14837 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
14839 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
14842 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
14843 check till after the cache is created in init_frame_faces.
14845 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
14847 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
14849 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
14851 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
14852 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
14853 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
14855 Improve buffer-overflow checking (Bug#8873).
14856 * fileio.c (Finsert_file_contents):
14857 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
14858 Remove the old (too-loose) buffer overflow checks.
14859 They weren't needed, since make_gap checks for buffer overflow.
14860 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
14861 The old code merely checked for Emacs fixnum overflow, and relied
14862 on undefined (wraparound) behavior. The new code avoids undefined
14863 behavior, and also checks for ptrdiff_t and/or size_t overflow.
14865 * editfns.c (Finsert_char): Don't dump core with very negative counts.
14866 Tune. Don't use wider integers than needed. Don't use alloca.
14867 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
14869 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
14871 * insdel.c, lisp.h (buffer_overflow): New function.
14872 (insert_from_buffer_1, replace_range, replace_range_2):
14873 * insdel.c (make_gap_larger):
14874 * editfns.c (Finsert_char):
14875 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
14877 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
14879 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
14881 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
14883 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
14884 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
14886 * fileio.c: Don't assume EMACS_INT fits in off_t.
14887 (emacs_lseek): New static function.
14888 (Finsert_file_contents, Fwrite_region): Use it.
14889 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
14891 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
14893 * fns.c: Don't overflow int when computing a list length.
14894 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
14895 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
14896 truncation on 64-bit hosts. Check for QUIT every
14897 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
14898 faster and is responsive enough.
14899 (Flength): Report an error instead of overflowing an integer.
14900 (Fsafe_length): Return a float if the value is not representable
14901 as a fixnum. This shouldn't happen except in contrived situations.
14902 (Fnthcdr, Fsort): Don't assume list length fits in int.
14903 (Fcopy_sequence): Don't assume vector length fits in int.
14905 * alloc.c: Check that resized vectors' lengths fit in fixnums.
14906 (header_size, word_size): New constants.
14907 (allocate_vectorlike): Don't check size overflow here.
14908 (allocate_vector): Check it here instead, since this is the only
14909 caller of allocate_vectorlike that could cause overflow.
14910 Check that the new vector's length is representable as a fixnum.
14912 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
14913 The previous code was bogus. For example, next_almost_prime (32)
14914 returned 39, which is undesirable as it is a multiple of 3; and
14915 next_almost_prime (24) returned 25, which is a multiple of 5 so
14916 why was the code bothering to check for multiples of 7?
14918 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
14920 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
14922 Variadic C functions now count arguments with ptrdiff_t.
14923 This partly undoes my 2011-03-30 change, which replaced int with size_t.
14924 Back then I didn't know that the Emacs coding style prefers signed int.
14925 Also, in the meantime I found a few more instances where arguments
14926 were being counted with int, which may truncate counts on 64-bit
14927 machines, or EMACS_INT, which may be unnecessarily wide.
14928 * lisp.h (struct Lisp_Subr.function.aMANY)
14929 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
14930 Arg counts are now ptrdiff_t, not size_t.
14931 All variadic functions and their callers changed accordingly.
14932 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
14933 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
14934 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
14935 * callint.c (Fcall_interactively): Check arg count for overflow,
14936 to avoid potential buffer overrun. Use signed char, not 'int',
14937 for 'varies' array, so that we needn't bother to check its size
14938 calculation for overflow.
14939 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
14940 * eval.c (apply_lambda):
14941 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
14942 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
14943 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
14945 * callint.c (Fcall_interactively): Don't use index var as event count.
14947 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
14948 * mem-limits.h (SIZE): Remove; no longer used.
14950 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
14952 Remove unnecessary casts.
14953 * xterm.c (x_term_init):
14954 * xfns.c (x_set_border_pixel):
14955 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
14956 These aren't needed now that we assume ANSI C.
14958 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
14959 It's more likely to cause problems (due to unsigned overflow)
14962 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
14964 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
14966 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
14968 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
14970 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
14972 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
14974 GLYPH_CODE_FACE returns EMACS_INT, not int.
14975 * dispextern.h (merge_faces):
14976 * xfaces.c (merge_faces):
14977 * xdisp.c (get_next_display_element, next_element_from_display_vector):
14978 Don't assume EMACS_INT fits in int.
14980 * character.h (CHAR_VALID_P): Remove unused parameter.
14981 * fontset.c, lisp.h, xdisp.c: All uses changed.
14983 * editfns.c (Ftranslate_region_internal): Omit redundant test.
14985 * fns.c (concat): Minor tuning based on overflow analysis.
14986 This doesn't fix any bugs. Use int to hold character, instead
14987 of constantly refetching from Emacs object. Use XFASTINT, not
14988 XINT, for value known to be a character. Don't bother comparing
14989 a single byte to 0400, as it's always less.
14991 * floatfns.c (Fexpt):
14992 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
14994 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
14997 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
14999 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
15000 Without this fix, on a 64-bit host (aset S 0 4294967386) would
15001 incorrectly succeed when S was a string, because 4294967386 was
15002 truncated before it was used.
15004 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
15005 Otherwise, an out-of-range integer could cause undefined behavior
15008 * composite.c: Use int, not EMACS_INT, for characters.
15009 (fill_gstring_body, composition_compute_stop_pos): Use int, not
15010 EMACS_INT, for values that are known to be in character range.
15011 This doesn't fix any bugs but is the usual style inside Emacs and
15012 may generate better code on 32-bit machines.
15014 Make sure a 64-bit char is never passed to ENCODE_CHAR.
15015 This is for reasons similar to the recent CHAR_STRING fix.
15016 * charset.c (Fencode_char): Check that character arg is actually
15017 a character. Pass an int to ENCODE_CHAR.
15018 * charset.h (ENCODE_CHAR): Verify that the character argument is no
15019 wider than 'int', as a compile-time check to prevent future regressions
15022 * character.c (char_string): Remove unnecessary casts.
15024 Make sure a 64-bit char is never passed to CHAR_STRING.
15025 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
15026 by silently ignoring the top 32 bits, allowing some values
15027 that were far too large to be valid characters.
15028 * character.h: Include <verify.h>.
15029 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
15030 arguments are no wider than unsigned, as a compile-time check
15031 to prevent future regressions in this area.
15033 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
15034 (Fsubst_char_in_region):
15036 * xdisp.c (decode_mode_spec_coding):
15037 Adjust to CHAR_STRING's new requirement.
15038 * editfns.c (Finsert_char, Fsubst_char_in_region):
15039 * fns.c (concat): Check that character args are actually
15040 characters. Without this test, these functions did the wrong
15041 thing with wildly out-of-range values on 64-bit hosts.
15043 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
15044 These casts should not be needed on 32-bit hosts, either.
15045 * keyboard.c (read_char):
15046 * lread.c (Fload): Remove casts to unsigned.
15048 * lisp.h (UNSIGNED_CMP): New macro.
15049 This fixes comparison bugs on 64-bit hosts.
15050 (ASCII_CHAR_P): Use it.
15051 * casefiddle.c (casify_object):
15052 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
15053 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
15054 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
15055 * dispextern.h (FACE_FROM_ID):
15056 * keyboard.c (read_char): Use UNSIGNED_CMP.
15058 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
15059 not to EMACS_INT, to avoid GCC warning.
15061 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
15063 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
15064 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
15065 isn't needed on 32-bit machines.
15067 * buffer.c (Fgenerate_new_buffer_name):
15068 Use EMACS_INT for count, not int.
15069 (advance_to_char_boundary): Return EMACS_INT, not int.
15071 * data.c (Qcompiled_function): Now static.
15073 * window.c (window_body_lines): Now static.
15075 * image.c (gif_load): Rename local to avoid shadowing.
15077 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
15078 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
15079 * alloc.c (make_save_value): Integer argument is now of type
15080 ptrdiff_t, not int.
15081 (mark_object): Use ptrdiff_t, not int.
15082 * lisp.h (pD): New macro.
15083 * print.c (print_object): Use it.
15085 * alloc.c: Use EMACS_INT, not int, to count objects.
15086 (total_conses, total_markers, total_symbols, total_vector_size)
15087 (total_free_conses, total_free_markers, total_free_symbols)
15088 (total_free_floats, total_floats, total_free_intervals)
15089 (total_intervals, total_strings, total_free_strings):
15090 Now EMACS_INT, not int. All uses changed.
15091 (Fgarbage_collect): Compute overall total using a double, so that
15092 integer overflow is less likely to be a problem. Check for overflow
15093 when converting back to an integer.
15094 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
15095 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
15096 These were 'int' variables that could overflow on 64-bit hosts;
15097 they were never used, so remove them instead of repairing them.
15098 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
15099 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
15100 Previously, this ceilinged at INT_MAX, but that doesn't work on
15102 (allocate_pseudovector): Don't use EMACS_INT when int would do.
15104 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
15105 (allocate_vectorlike): Check for ptrdiff_t overflow.
15106 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
15107 when a (possibly-narrower) signed value would do just as well.
15108 We prefer using signed arithmetic, to avoid comparison confusion.
15110 * alloc.c: Catch some string size overflows that we were missing.
15111 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
15112 for convenience in STRING_BYTES_MAX.
15113 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
15114 The definition here is exact; the one in lisp.h was approximate.
15115 (allocate_string_data): Check for string overflow. This catches
15116 some instances we weren't catching before. Also, it catches
15117 size_t overflow on (unusual) hosts where SIZE_MAX <= min
15118 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
15119 and ptrdiff_t and EMACS_INT are both 64 bits.
15121 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
15122 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
15123 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
15125 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
15127 * alloc.c (Fmake_string): Check for out-of-range init.
15129 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
15131 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
15133 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
15135 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
15136 xg_get_default_scrollbar_width.
15138 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
15139 (int_gtk_range_get_value): Move to the scroll bar part of the file.
15140 (style_changed_cb): Call update_theme_scrollbar_width and call
15141 x_set_scroll_bar_default_width and xg_frame_set_char_size for
15142 all frames (Bug#8505).
15143 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
15144 Call gtk_window_set_resizable if HAVE_GTK3.
15145 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
15146 and height if HAVE_GTK3 (Bug#8505).
15147 (scroll_bar_width_for_theme): New variable.
15148 (update_theme_scrollbar_width): New function.
15149 (xg_get_default_scrollbar_width): Move code to
15150 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
15151 (xg_initialize): Call update_theme_scrollbar_width.
15153 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
15155 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
15157 2011-06-12 Martin Rudalics <rudalics@gmx.at>
15159 * frame.c (make_frame): Call other_buffer_safely instead of
15162 * window.c (temp_output_buffer_show): Call display_buffer with
15163 second argument Vtemp_buffer_show_specifiers and reset latter
15164 immediately after the call.
15165 (Vtemp_buffer_show_specifiers): New variable.
15166 (auto_window_vscroll_p, next_screen_context_lines)
15167 (Vscroll_preserve_screen_position): Remove leading asterisks from
15170 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
15172 Fix minor problems found by GCC 4.6.0 static checking.
15173 * buffer.c (Qclone_number): Remove for now, as it's unused.
15174 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
15175 (record_buffer): Remove unused local.
15176 * frame.c (other_visible_frames, frame_buffer_list): Now static.
15177 (set_frame_buffer_list): Remove; unused.
15178 * frame.h (other_visible_frames): Remove decl.
15179 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
15180 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
15181 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
15183 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
15184 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
15185 Define only if HAVE_GPM.
15186 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
15187 (update_hints_inhibit): Remove; never set. All uses removed.
15188 * widgetprv.h (emacsFrameClassRec): Remove decl.
15189 * window.c (delete_deletable_window): Now returns void, since it
15190 wasn't returning anything.
15191 (compare_window_configurations): Remove unused locals.
15192 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
15193 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.

15661 New error handlers.
15662 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
15663 Obey Vx_select_enable_clipboard_manager. Catch errors in
15664 x_clipboard_manager_save (Bug#8779).
15665 (Vx_select_enable_clipboard_manager): New variable.
15666 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
15668 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
15670 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
15672 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15674 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
15675 in the current matrix if keep_current_p is non-zero.

15679 * bidi.c (bidi_level_of_next_char): Fix last change.
15681 2011-06-03 Eli Zaretskii <eliz@gnu.org>
15683 Support bidi reordering of text covered by display properties.
15685 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
15686 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
15687 (bidi_cache_search, bidi_cache_iterator_state)
15688 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
15689 (bidi_level_of_next_char, bidi_move_to_visually_next):
15690 Support character positions inside a run of characters covered by a
15692 (bidi_paragraph_init, bidi_resolve_explicit_1)
15693 (bidi_level_of_next_char): Call bidi_fetch_char and
15694 bidi_fetch_char_advance instead of FETCH_CHAR and
15695 FETCH_CHAR_ADVANCE.
15696 (bidi_init_it): Initialize new members.
15697 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
15699 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
15700 instead of using explicit *_CHAR codes.
15701 (bidi_resolve_explicit, bidi_resolve_weak):
15702 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
15703 bidirectional text is supported only in multibyte buffers.
15704 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
15705 it to initialize the frame_window_p member of struct bidi_it.
15706 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
15707 (bidi_resolve_explicit, bidi_resolve_weak)

15709 bidi_it->nchars is non-positive.
15710 (bidi_level_of_next_char): Don't try to lookup the cache for the
15711 next/previous character if nothing is cached there yet, or if we
15712 were just reseat()'ed to a new position.
15714 * xdisp.c (set_cursor_from_row): Set start and stop points
15715 according to the row's direction when priming the loop that looks
15716 for the glyph on which to display cursor.
15717 (single_display_spec_intangible_p): Function deleted.
15718 (display_prop_intangible_p): Reimplement to call
15719 handle_display_spec instead of single_display_spec_intangible_p.
15720 Accept 3 additional arguments needed by handle_display_spec.
15721 This fixes incorrect cursor motion across display property with complex
15722 values: lists, `(when COND...)' forms, etc.
15723 (single_display_spec_string_p): Support property values that are
15724 lists with the argument STRING its top-level element.
15725 (display_prop_string_p): Fix the condition for processing a
15726 property that is a list to be consistent with handle_display_spec.
15727 (handle_display_spec): New function, refactored from the
15728 last portion of handle_display_prop.
15729 (compute_display_string_pos): Accept additional argument
15730 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
15731 value of a `display' property is a "replacing spec".
15732 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
15733 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
15734 the display property, but just return a value indicating whether
15735 the display property will replace the characters it covers.
15736 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
15737 frame_window_p members of struct bidi_it.
15738 (compute_display_string_pos, compute_display_string_end):
15740 (push_it): Accept second argument POSITION, where pop_it should
15741 jump to continue iteration.
15742 (reseat_1): Initialize bidi_it.disp_pos.
15744 * keyboard.c (adjust_point_for_property): Adjust the call to
15745 display_prop_intangible_p to its new signature.
15747 * dispextern.h (struct bidi_it): New member frame_window_p.
15748 (bidi_init_it): Update prototypes.
15749 (display_prop_intangible_p): Update prototype.
15750 (compute_display_string_pos, compute_display_string_end):
15751 Declare prototypes.
15752 (struct bidi_it): New members nchars and disp_pos. ch_len is now
15755 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
15757 Malloc failure behavior now depends on size of allocation.
15758 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
15759 * lisp.h: Change signatures accordingly.
15760 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
15761 All callers changed. (Bug#8762)
15763 * gnutls.c: Use Emacs's memory allocators.
15764 Without this change, the gnutls library would invoke malloc etc.
15765 directly, which causes problems on non-SYNC_INPUT hosts, and which
15766 runs afoul of improving memory_full behavior. (Bug#8761)
15767 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
15768 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
15769 xfree instead of the default malloc, realloc, free.
15770 (Fgnutls_boot): No need to check for memory allocation failure,
15771 since xmalloc does that for us.
15773 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
15774 * category.c (hash_get_category_set):
15775 * ccl.c (ccl_driver):
15776 * charset.c (Fdefine_charset_internal):
15777 * charset.h (struct charset.hash_index):

15786 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
15787 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
15788 (Fsxhash, Fgethash, Fputhash, Fmaphash):
15789 * image.c (make_image, search_image_cache, lookup_image)
15790 (xpm_put_color_table_h):
15791 * lisp.h (struct Lisp_Hash_Table):
15792 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
15793 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
15794 for hashes and hash indexes, instead of 'unsigned' and 'int'.
15795 * alloc.c (allocate_vectorlike):
15796 Check for overflow in vector size calculations.
15797 * ccl.c (ccl_driver):
15798 Check for overflow when converting EMACS_INT to int.
15799 * fns.c, image.c: Remove unnecessary static decls that would otherwise
15800 need to be updated by these changes.
15801 * fns.c (make_hash_table, maybe_resize_hash_table):
15802 Check for integer overflow with large hash tables.
15803 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
15804 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
15805 (SXHASH_REDUCE): New macro.
15806 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
15807 Use it instead of discarding useful hash info with large hash values.
15808 (sxhash_float): New function.
15809 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
15810 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
15811 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
15812 Rewrite to use FIXNUM_BITS, as this simplifies things.
15813 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
15814 Adjust signatures to match updated version of code.
15815 (consing_since_gc): Now EMACS_INT, since a single hash table can
15816 use more than INT_MAX bytes.
15818 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
15820 Make it possible to build with GCC-4.6+ -O2 -flto.
15822 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
15824 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
15826 * minibuf.c (get_minibuffer, read_minibuf_unwind):
15827 Call minibuffer-inactive-mode.
15829 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
15831 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
15832 Update dependencies.
15834 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15836 * data.c (init_data): Remove code for UTS, this system is not
15839 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15841 Don't force ./temacs to start in terminal mode.
15843 * frame.c (make_initial_frame): Initialize faces in all cases, not
15844 only when CANNOT_DUMP is defined.
15845 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
15847 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15849 * dispnew.c (add_window_display_history): Use const for the string
15850 pointer. Remove declaration, not needed.
15852 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
15854 Use 'inline', not 'INLINE'.
15855 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
15856 * alloc.c, fontset.c (INLINE): Remove.
15857 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
15858 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
15859 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
15860 * gmalloc.c (register_heapinfo): Use inline unconditionally.
15861 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
15863 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15865 Make it possible to run ./temacs.
15867 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
15868 syms_of_callproc does the same thing. Remove test for
15869 "initialized", do it in the caller.
15870 * emacs.c (main): Avoid calling set_initial_environment when dumping.
15872 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
15874 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
15875 (read_minibuf): Use get_minibuffer.
15876 (syms_of_minibuf): Use DEFSYM.
15877 (Qmetadata): New var.
15878 * data.c (Qbuffer): Don't make it static.
15879 (syms_of_data): Use DEFSYM.
15881 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
15883 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
15884 (CCL_CODE_MIN): New macro.
15886 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
15888 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
15890 * eval.c (Qdebug): Now static.
15891 * lisp.h (Qdebug): Remove decl. This reverts a part of the
15892 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
15893 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
15895 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
15897 * image.c: Various fixes to ImageMagick code comments.
15898 (Fimagemagick_types): Doc fix.
15900 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
15902 Minor fixes prompted by GCC 4.6.0 warnings.
15904 * xselect.c (converted_selections, conversion_fail_tag): Now static.
15906 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
15907 (x_clipboard_manager_save_all): Move extern decl to ...
15908 * xterm.h: ... here, so that it can be checked for consistency.
15910 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
15912 * xselect.c (x_clipboard_manager_save_frame)
15913 (x_clipboard_manager_save_all): New functions.
15914 (Fx_clipboard_manager_save): Lisp function deleted.
15916 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
15917 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
15919 * xterm.h: Update prototype.
15921 2011-05-28 William Xu <william.xwl@gmail.com>
15923 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
15924 exiting (Bug#8239).
15926 2011-05-28 Jim Meyering <meyering@redhat.com>
15928 Avoid a sign-extension bug in crypto_hash_function.
15929 * fns.c (to_uchar): Define.
15930 (crypto_hash_function): Use it to convert some newly-signed
15931 variables to unsigned, to avoid sign-extension bugs. For example,
15932 without this change, (md5 "truc") would evaluate to
15933 45723a2aff78ff4fff7fff1114760e62 rather than the expected
15934 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
15935 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
15937 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
15939 Integer overflow fixes.
15941 * dbusbind.c: Serial number integer overflow fixes.
15942 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
15943 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
15944 to hold a serial number that is too large for a fixnum.
15945 (Fdbus_method_return_internal, Fdbus_method_error_internal):
15946 Check for serial numbers out of range. Decode any serial number
15947 that was so large that it became a float. (Bug#8722)
15949 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
15950 (Fdbus_call_method, Fdbus_call_method_asynchronously):
15951 Use XFASTINT rather than XUINT when numbers are nonnegative.
15952 (xd_append_arg, Fdbus_method_return_internal):
15953 (Fdbus_method_error_internal): Likewise. Also, for unsigned
15954 arguments, check that Lisp number is nonnegative, rather than
15955 silently wrapping negative numbers around. (Bug#8722)
15956 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
15959 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
15961 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
15963 ccl: Add integer overflow checks.
15964 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
15965 (IN_INT_RANGE): New macros.
15966 (ccl_driver): Use them to check for integer overflow when
15967 decoding a CCL program. Many of the new checks are whether XINT (x)
15968 fits in int; it doesn't always, on 64-bit hosts. The new version
15969 doesn't catch all possible integer overflows, but it's an
15970 improvement. (Bug#8719)
15972 * alloc.c (make_event_array): Use XINT, not XUINT.
15973 There's no need for unsigned here.
15975 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
15976 This follows up to the 2011-05-06 change that substituted uintptr_t
15977 for EMACS_INT. This case wasn't caught back then.
15979 Rework Fformat to avoid integer overflow issues.
15980 * editfns.c: Include <float.h> unconditionally, as it's everywhere
15981 now (part of C89). Include <verify.h>.
15982 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
15983 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
15984 (Fformat): Avoid the prepass trying to compute sizes; it was only
15985 approximate and thus did not catch overflow reliably. Instead, walk
15986 through the format just once, formatting and computing sizes as we go,
15987 checking for integer overflow at every step, and allocating a larger
15988 buffer as needed. Keep track separately whether the format is
15989 multibyte. Keep only the most-recently calculated precision, rather
15990 than them all. Record whether each argument has been converted to
15991 string. Use EMACS_INT, not int, for byte and char and arg counts.
15992 Support field widths and precisions larger than INT_MAX. Avoid
15993 sprintf's undefined behavior with conversion specifications such as %#d
15994 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
15995 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
15996 formatting out-of-range floating point numbers with int
15997 formats. (Bug#8668)
15999 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
16001 * data.c: Avoid integer truncation in expressions involving floats.
16002 * data.c: Include <intprops.h>.
16003 (arith_driver): When there's an integer overflow in an expression
16004 involving floating point, convert the integers to floating point
16005 so that the resulting value does not suffer from catastrophic
16006 integer truncation. For example, on a 64-bit host (* 4
16007 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
16008 Do not rely on undefined behavior after integer overflow.
16010 merge count_size_as_multibyte, parse_str_to_multibyte
16011 * character.c, character.h (count_size_as_multibyte):
16012 Rename from parse_str_to_multibyte; all uses changed.
16013 Check for integer overflow.
16014 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
16015 since it's now a duplicate of the other. This is more of
16016 a character than a buffer op, so better that it's in character.c.
16017 * fns.c, print.c: Adjust to above changes.
16019 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
16021 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
16023 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
16025 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
16026 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
16027 (x_clipboard_manager_save): Now static.
16028 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
16030 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
16031 (crypto_hash_function): Now static.
16032 Fix pointer signedness problems. Avoid unnecessary initializations.
16034 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
16036 * termhooks.h (Vselection_alist): Make it terminal-local.
16038 * terminal.c (create_terminal): Initialize it.
16040 * xselect.c: Support for clipboard managers.
16041 (Vselection_alist): Move to termhooks.h as terminal-local var.
16042 (LOCAL_SELECTION): New macro.
16043 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
16044 (symbol_to_x_atom): Remove gratuitous arg.
16045 (x_handle_selection_request, lisp_data_to_selection_data)
16046 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
16047 (x_own_selection, x_get_local_selection, x_convert_selection):
16048 New arg, specifying work frame. Use terminal-local Vselection_alist.
16049 (some_frame_on_display): Delete unused function.
16050 (Fx_own_selection_internal, Fx_get_selection_internal)
16051 (Fx_disown_selection_internal, Fx_selection_owner_p)
16052 (Fx_selection_exists_p): New optional frame arg.
16053 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
16054 (x_handle_selection_clear): Don't treat other terminals with the
16055 same keyboard specially. Use the terminal-local Vselection_alist.
16056 (x_clear_frame_selections): Use Frun_hook_with_args.
16058 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
16060 * xterm.h: Add support for those atoms.
16062 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
16064 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
16065 (converted_selections, conversion_fail_tag): New global variables.
16066 (x_selection_request_lisp_error): Free the above.
16067 (x_get_local_selection): Remove unnecessary code.
16068 (x_reply_selection_request): Args changed; handle arbitrary array
16069 of converted selections stored in converted_selections.
16070 Separate the XChangeProperty and SelectionNotify steps.
16071 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
16072 (x_convert_selection): New function.
16073 (x_handle_selection_event): Simplify.
16074 (x_get_foreign_selection): Don't ignore incoming requests while
16075 waiting for an answer; this will fail when we implement
16076 SAVE_TARGETS, and seems unnecessary anyway.
16077 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
16078 (Vx_sent_selection_functions): Doc fix.
16080 2011-05-26 Leo Liu <sdl.web@gmail.com>
16082 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
16084 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16086 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
16088 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
16089 for fringe update if it has periodic bitmap.
16090 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
16091 and fringe_bitmap_periodic_p.
16093 * fringe.c (get_fringe_bitmap_data): New function.
16094 (draw_fringe_bitmap_1, update_window_fringes): Use it.
16095 (update_window_fringes): Record periodicity of fringe bitmap in glyph
16096 row. Mark glyph row for fringe update if periodicity changed.
16098 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
16099 for fringe update unless it has periodic bitmap.
16101 2011-05-25 Kenichi Handa <handa@m17n.org>
16103 * xdisp.c (get_next_display_element): Set correct it->face_id for
16104 a static composition.
16106 2011-05-24 Leo Liu <sdl.web@gmail.com>
16109 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
16111 * fns.c (crypto_hash_function, Fsha1): New function.
16112 (Fmd5): Use crypto_hash_function.
16113 (syms_of_fns): Add Ssha1.
16115 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
16117 * gnutls.c: Remove unused macros.
16118 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
16119 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
16120 Remove macros that are defined and never used.
16121 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
16123 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
16125 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
16126 (Fx_get_selection_internal): Minor cleanup.
16127 (Fx_own_selection_internal): Rename arguments for consistency with
16130 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
16132 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
16134 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
16136 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
16138 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16140 * dispnew.c (scrolling_window): Don't exclude the case that the
16141 last enabled row in the desired matrix touches the bottom boundary.
16143 2011-05-21 Glenn Morris <rgm@gnu.org>
16145 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
16146 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
16147 and add some more files.
16149 2011-05-20 Eli Zaretskii <eliz@gnu.org>
16151 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
16152 report_file_error introduced by the change from 2011-05-07.
16154 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
16156 * systime.h (Time): Define only if emacs is defined.
16157 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
16158 where the include path doesn't have X11/X.h by default. See
16159 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
16161 2011-05-20 Kenichi Handa <handa@m17n.org>
16163 * composite.c (find_automatic_composition): Fix previous change.
16165 2011-05-20 Glenn Morris <rgm@gnu.org>
16167 * lisp.mk: New file, split from Makefile.in.
16168 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
16169 (shortlisp): Remove.
16170 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
16172 2011-05-19 Glenn Morris <rgm@gnu.org>
16174 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
16175 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
16176 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
16177 (lisp): Set the order to that of loadup.el.
16178 (shortlisp): Make it a copy of $lisp.
16179 (SOME_MACHINE_LISP): Remove.
16180 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
16181 Use just $shortlisp, not $SOME_MACHINE_LISP too.
16183 2011-05-18 Kenichi Handa <handa@m17n.org>
16185 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
16186 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
16187 (find_automatic_composition): Mostly rewrite for efficiency.
16189 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
16191 * makefile.w32-in: Update dependencies.
16193 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
16195 * menu.c: Include limits.h (fixes the MS-Windows build broken by
16196 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
16198 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
16200 Fix some integer overflow issues, such as string length overflow.
16202 * insdel.c (count_size_as_multibyte): Check for string overflow.
16204 * character.c (lisp_string_width): Check for string overflow.
16205 Use EMACS_INT, not int, for string indexes and lengths; in
16206 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
16207 the resulting string length overflows an EMACS_INT; instead,
16208 report a string overflow if no precision given. When checking for
16209 precision exhaustion, use a check that cannot possibly have
16210 integer overflow. (Bug#8675)
16211 * character.h (lisp_string_width): Adjust to new signature.
16213 * alloc.c (string_overflow): New function.
16214 (Fmake_string): Use it. This doesn't change behavior, but saves
16215 a few bytes and will simplify future changes.
16216 * character.c (string_escape_byte8): Likewise.
16217 * lisp.h (string_overflow): New decl.
16219 Fixups, following up to the user-interface timestamp change.
16220 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
16221 for UI timestamps, instead of unsigned long.
16222 * msdos.c (mouse_get_pos): Likewise.
16223 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
16224 * w32gui.h (Time): Define by including "systime.h" rather than by
16225 declaring it ourselves. (Bug#8664)
16227 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
16228 * image.c (clear_image_cache): Likewise.
16230 * term.c (term_mouse_position): Don't assume time_t wraparound.
16232 Be more systematic about user-interface timestamps.
16233 Before, the code sometimes used 'Time', sometimes 'unsigned long',
16234 and sometimes 'EMACS_UINT', to represent these timestamps.
16235 This change causes it to use 'Time' uniformly, as that's what X uses.
16236 This makes the code easier to follow, and makes it easier to catch
16237 integer overflow bugs such as Bug#8664.
16238 * frame.c (Fmouse_position, Fmouse_pixel_position):
16239 Use Time, not unsigned long, for user-interface timestamps.
16240 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
16241 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
16242 * keyboard.h (last_event_timestamp): Likewise.
16243 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
16244 * menu.h (xmenu_show): Likewise.
16245 * term.c (term_mouse_position): Likewise.
16246 * termhooks.h (struct input_event.timestamp): Likewise.
16247 (struct terminal.mouse_position_hook): Likewise.
16248 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
16249 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
16250 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
16251 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
16252 what it was before.
16253 * menu.h, termhooks.h: Include "systime.h", for Time.
16255 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
16256 Don't assume that the difference between two unsigned long values
16257 can fit into an integer. At this point, we know button_down_time
16258 <= event->timestamp, so the difference must be nonnegative, so
16259 there's no need to cast the result if double-click-time is
16260 nonnegative, as it should be; check that it's nonnegative, just in
16261 case. This bug is triggered when events are more than 2**31 ms
16262 apart (about 25 days). (Bug#8664)
16264 * xselect.c (last_event_timestamp): Remove duplicate decl.
16265 (x_own_selection): Remove needless cast to unsigned long.
16267 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
16268 that always fit in int. Use a sentinel instead of a counter, to
16269 avoid a temp and to allay GCC's concerns about possible int overflow.
16270 * frame.h (struct frame): Use int for menu_bar_items_used
16271 instead of EMACS_INT, since it always fits in int.
16273 * menu.c (grow_menu_items): Check for int overflow.
16275 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
16277 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
16278 Before, the code was not consistent. These values cannot exceed
16279 2**31 - 1 so there's no need to make them unsigned.
16280 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
16281 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
16282 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
16284 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
16286 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
16287 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
16288 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
16289 presumably because the widths might not match.
16291 * window.c (size_window): Avoid needless test at loop start.
16293 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
16295 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
16297 2011-05-12 Drew Adams <drew.adams@oracle.com>
16299 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
16301 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16303 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
16304 `width' to `bar_area_x' and `bar_area_width', respectively.
16305 (x_scroll_run): Take account of fringe background extension.
16307 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
16308 Rename local vars `left' and `width' to `bar_area_x' and
16309 `bar_area_width', respectively.
16310 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
16311 background extension.
16313 2011-05-10 Jim Meyering <meyering@redhat.com>
16315 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
16317 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
16319 * image.c (Finit_image_library): Return t for built-in image types,
16320 like pbm and xbm. (Bug#8640)
16322 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
16324 * w32menu.c (set_frame_menubar): Fix submenu allocation.
16326 2011-05-07 Eli Zaretskii <eliz@gnu.org>
16328 * w32console.c (Fset_screen_color): Doc fix.
16329 (Fget_screen_color): New function.
16330 (syms_of_ntterm): Defsubr it.
16332 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
16333 unlink the temporary file if Fcall_process didn't create it in the
16335 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
16336 child process will be redirected to a file specified with `:file'.
16337 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
16338 cue to call_process_cleanup not to close that handle.
16340 2011-05-07 Ben Key <bkey76@gmail.com>
16342 * makefile.w32-in: The bootstrap-temacs rule now makes use of
16343 one of two shell specific rules, either bootstrap-temacs-CMD or
16344 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
16345 to the previous implementation of the bootstrap-temacs rule.
16346 The bootstrap-temacs-CMD rule is similar to the previous
16347 implementation of the bootstrap-temacs rule except that it
16348 makes use of the ESC_CFLAGS variable instead of the CFLAGS
16351 These changes, along with some changes to nt/configure.bat,
16352 nt/gmake.defs, and nt/nmake.defs, are required to extend my
16353 earlier fix to add support for --cflags and --ldflags options
16354 that include quotes so that it works whether make uses cmd or
16357 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
16359 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
16360 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
16362 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
16363 a string. Handle both cases.
16364 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
16365 (Fdbus_register_method): Use Qinvalid_function.
16367 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
16369 * makefile.w32-in: Update dependencies.
16370 (LISP_H): Add inttypes.h and stdin.h.
16371 (PROCESS_H): Add unistd.h.
16373 2011-05-06 Eli Zaretskii <eliz@gnu.org>
16375 * lread.c: Include limits.h (fixes the MS-Windows build broken by
16376 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
16378 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
16380 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
16382 * term.c (vfatal): Remove stray call to va_end.
16383 It's not needed and the C Standard doesn't allow it here anyway.
16385 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
16386 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
16388 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
16391 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
16393 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16395 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
16397 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
16399 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
16401 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
16402 * charset.c (Fdefine_charset_internal): Don't initialize
16403 charset.code_space[15]. The value was garbage, on hosts with
16404 32-bit int (Bug#8600).
16406 * lread.c (read_integer): Be more consistent with string-to-number.
16407 Use string_to_number to do the actual conversion; this avoids
16408 rounding errors and fixes some other screwups. Without this fix,
16409 for example, #x1fffffffffffffff was misread as -2305843009213693952.
16410 (digit_to_number): Move earlier, for benefit of read_integer.
16411 Return -1 if the digit is out of range for the base, -2 if it is
16412 not a digit in any supported base. (Bug#8602)
16414 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
16416 * dispnew.c (scrolling_window): Return 1 if we scrolled,
16417 to match comment at start of function. This also removes a
16418 GCC warning about overflow in a 32+64-bit port.
16420 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
16422 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
16423 Reported by Stefan Monnier in
16424 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
16425 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
16426 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
16428 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
16429 (EMACS_UINTPTR): Likewise, with uintptr_t.
16431 * lisp.h: Prefer 64-bit EMACS_INT if available.
16432 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
16433 on 32-bit hosts that have 64-bit int, so that they can access
16435 However, temporarily disable this change unless the temporary
16436 symbol WIDE_EMACS_INT is defined.
16438 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
16440 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
16441 This removes an assumption that EMACS_INT and long are the same
16442 width as pointers. The assumption is true for Emacs porting targets
16443 now, but we want to make other targets possible.
16444 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
16445 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
16446 In the rest of the code, change types of integers that hold casted
16447 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
16448 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
16449 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
16450 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
16451 No need to cast type when ORing.
16452 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
16453 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
16454 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
16455 assume EMACS_INT is the same width as char *.
16456 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
16457 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
16458 Remove no-longer-needed casts.
16459 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
16460 (xg_tool_bar_help_callback, xg_make_tool_item):
16461 Use EMACS_INTPTR to hold an integer
16462 that will be cast to void *; this can avoid a GCC warning
16463 if EMACS_INT is not the same width as void *.
16464 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
16465 * xdisp.c (display_echo_area_1, resize_mini_window_1):
16466 (current_message_1, set_message_1):
16467 Use a local to convert to proper width without a cast.
16468 * xmenu.c (dialog_selection_callback): Likewise.
16470 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
16471 Also, don't assume VALBITS / RAND_BITS is less than 5,
16472 and don't rely on undefined behavior when shifting a 1 left into
16474 * lisp.h (get_random): Change signature to match.
16476 * lread.c (hash_string): Use size_t, not int, for hash computation.
16477 Normally we prefer signed values; but hashing is special, because
16478 it's better to use unsigned division on hash table sizes so that
16479 the remainder is nonnegative. Also, size_t is the natural width
16480 for hashing into memory. The previous code used 'int', which doesn't
16481 retain enough info to hash well into very large tables.
16482 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
16484 * dbusbind.c: Don't possibly lose pointer info when converting.
16485 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
16486 Use XPNTR rather than XHASH, so that the high-order bits of
16487 the pointer aren't lost when converting through void *.
16489 * eval.c (Fautoload): Don't double-shift a pointer.
16491 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
16493 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
16495 * gnutls.c (DEF_GNUTLS_FN):
16496 * image.c (DEF_IMGLIB_FN): Make function pointers static.

16574 * process.c: Include lisp.h before w32.h, not after.
16575 (wait_reading_process_output): Call emacs_gnutls_record_check_pending

16580 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
16582 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options

16628 rather than `XVECTOR (FOO)->size'.
16630 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
16631 inttypes.h, as a gnulib replacement is used if it not available in
16634 2011-04-21 Eli Zaretskii <eliz@gnu.org>
16636 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.

16646 charbuf for the composition carryover bytes.
16648 2011-04-21 Eli Zaretskii <eliz@gnu.org>
16650 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
16651 aborting when %lld or %lll format is passed.
16652 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
16653 %llo or %llx format is passed. (Bug#8545)
16655 * window.c (window_scroll_line_based): Use a marker instead of
16656 simple variables to record original value of point. (Bug#7952)
16658 * doprnt.c (doprnt): Fix the case where a multibyte sequence
16659 produced by %s or %c overflows available buffer space. (Bug#8545)
16661 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
16663 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
16664 (SIZE_MAX): Move defn after all includes, as they might #define it.
16666 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
16668 * w32.c (init_environment): Warn about defaulting HOME to C:\.
16670 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
16672 * keyboard.c (Qdelayed_warnings_hook): Define.
16673 (command_loop_1): Run `delayed-warnings-hook'
16674 if Vdelayed_warnings_list is non-nil.
16675 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
16676 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
16678 2011-04-28 Eli Zaretskii <eliz@gnu.org>
16680 * doprnt.c (doprnt): Don't return value smaller than the buffer
16681 size if the message was truncated. (Bug#8545).
16683 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
16685 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
16686 (Fx_window_property): #if-0 the whole functions, not just the bodies.
16688 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
16690 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
16692 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
16694 * makefile.w32-in: Update dependencies.
16696 2011-04-27 Eli Zaretskii <eliz@gnu.org>
16698 Improve `doprnt' and its usage. (Bug#8545)
16699 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
16700 `format_end'. Remove support for %l as a conversion specifier.
16701 Don't use xrealloc. Improve diagnostics when the %l size modifier
16702 is used. Update the commentary.
16704 * eval.c (verror): Simplify calculation of size_t.
16706 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
16709 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
16711 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
16714 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
16716 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
16717 This makes this file independent of the recent pseudovector change.
16719 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
16721 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
16723 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
16724 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
16725 Remove unused local.
16726 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
16728 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
16729 GCC 4.6.0 optimizes based on type-based alias analysis.
16730 For example, if b is of type struct buffer * and v of type struct
16731 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
16732 != &v->size, and therefore "v->size = 1; b->size = 2; return
16733 v->size;" must therefore return 1. This assumption is incorrect
16734 for Emacs, since it type-puns struct Lisp_Vector * with many other
16735 types. To fix this problem, this patch adds a new type struct
16736 vectorlike_header that documents the constraints on layout of vectors
16737 and pseudovectors, and helps optimizing compilers not get fooled
16738 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
16739 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
16740 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
16742 (XSETPVECTYPE): Rewrite in terms of new macro.
16743 (XSETPVECTYPESIZE): New macro, specifying both type and size.
16744 This is a bit clearer, and further avoids the possibility of
16745 undesirable aliasing.
16746 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
16747 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
16748 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
16749 since Lisp_Subr is a special case (no "next" field).
16750 (ASIZE): Now uses header.size rather than size.
16751 All previous uses of XVECTOR (foo)->size replaced to use this macro,
16752 to avoid the hassle of writing XVECTOR (foo)->header.size.
16753 (struct vectorlike_header): New type.
16754 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
16755 object, to help avoid aliasing.
16756 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
16757 (SUBRP): Likewise, since Lisp_Subr is a special case.
16758 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
16759 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
16760 (struct Lisp_Hash_Table): Combine first two members into a single
16761 struct vectorlike_header member. All uses of "size" and "next" members
16762 changed to be "header.size" and "header.next".
16763 * buffer.h (struct buffer): Likewise.
16764 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
16765 * frame.h (struct frame): Likewise.
16766 * process.h (struct Lisp_Process): Likewise.
16767 * termhooks.h (struct terminal): Likewise.
16768 * window.c (struct save_window_data, struct saved_window): Likewise.
16769 * window.h (struct window): Likewise.
16770 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
16771 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
16772 * buffer.c (init_buffer_once): Likewise.
16773 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
16775 * process.c (Fformat_network_address): Use local var for size,
16778 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
16780 Make the Lisp reader and string-to-float more consistent (Bug#8525)
16781 * data.c (atof): Remove decl; no longer used or needed.
16782 (digit_to_number): Move to lread.c.
16783 (Fstring_to_number): Use new string_to_number function, to be
16784 consistent with how the Lisp reader treats infinities and NaNs.
16785 Do not assume that floating-point numbers represent EMACS_INT
16786 without losing information; this is not true on most 64-bit hosts.
16787 Avoid double-rounding errors, by insisting on integers when
16788 parsing non-base-10 numbers, as the documentation specifies.
16789 * lisp.h (string_to_number): New decl, replacing ...
16790 (isfloat_string): Remove.
16791 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
16792 (read1): Do not accept +. and -. as integers; this
16793 appears to have been a coding error. Similarly, do not accept
16794 strings like +-1e0 as floating point numbers. Do not report
16795 overflow for integer overflows unless the base is not 10 which
16796 means we have no simple and reliable way to continue.
16797 Break out the floating-point parsing into a new
16798 function string_to_number, so that Fstring_to_number parses
16799 floating point numbers consistently with the Lisp reader.
16800 (digit_to_number): Move here from data.c. Make it static inline.
16801 (E_CHAR, EXP_INT): Remove, replacing with ...
16802 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
16803 (string_to_number): New function, replacing isfloat_string.
16804 This function checks for valid syntax and produces the resulting
16805 Lisp float number too. Rework it so that string-to-number
16806 no longer mishandles examples like "1.0e+". Use strtoumax,
16807 so that overflow for non-base-10 numbers is reported only when
16808 there's no portable and simple way to convert to floating point.
16810 * textprop.c (set_text_properties_1): Rewrite for clarity,
16811 and to avoid GCC warning about integer overflow.
16813 * intervals.h (struct interval): Use EMACS_INT for members
16814 where EMACS_UINT might cause problems. See
16815 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
16816 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
16817 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
16819 (offset_intervals): Tell GCC not to worry about length overflow
16820 when negating a negative length.
16822 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
16823 (overrun_check_free): Likewise.
16825 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
16826 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
16829 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
16830 (gnutls_make_error): Rename local to avoid shadowing.
16831 (gnutls_emacs_global_deinit): ifdef out; not used.
16832 (Fgnutls_boot): Use const for pointer to readonly storage.
16833 Comment out unused local. Fix pointer signedness problems.
16835 * lread.c (openp): Don't stuff size_t into an 'int'.
16836 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
16837 about possible signed overflow.
16839 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
16840 (GDK_KEY_g): Don't define if already defined.
16841 (xg_prepare_tooltip): Avoid pointer signedness problem.
16842 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
16844 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
16845 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
16847 * xfns.c (Fx_window_property): Simplify a bit,
16848 to make a bit faster and to avoid GCC 4.6.0 warning.
16849 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
16851 * fns.c (internal_equal): Don't assume size_t fits in int.
16853 * alloc.c (compact_small_strings): Tighten assertion a little.
16855 Replace pEd with more-general pI, and fix some printf arg casts.
16856 * lisp.h (pI): New macro, generalizing old pEd macro to other
16857 conversion specifiers. For example, use "...%"pI"d..." rather
16858 than "...%"pEd"...".
16859 (pEd): Remove. All uses replaced with similar uses of pI.
16860 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
16861 * alloc.c (check_pure_size): Don't overflow by converting size to int.
16862 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
16863 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
16864 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
16865 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
16866 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
16868 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
16869 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
16870 * print.c (safe_debug_print, print_object): Likewise.
16871 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
16873 Use pI instead of if-then-else-abort. Use %p to avoid casts,
16874 avoiding the 0 flag, which is not portable.
16875 * process.c (Fmake_network_process): Use pI to avoid cast.
16876 * region-cache.c (pp_cache): Likewise.
16877 * xdisp.c (decode_mode_spec): Likewise.
16878 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
16879 behavior on 64-bit hosts with printf arg.
16880 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
16881 (x_stop_queuing_selection_requests): Likewise.
16882 (x_get_window_property): Don't truncate byte count to an 'int'
16885 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
16886 here, since it parses constructs like leading '-' and spaces,
16887 which are not wanted; and it overflows with large numbers.
16888 Instead, simply match F[0-9]+, which is what is wanted anyway.
16890 * alloc.c: Remove unportable assumptions about struct layout.
16891 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
16892 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
16893 (allocate_vectorlike, make_pure_vector): Use the new macros,
16894 plus offsetof, to remove unportable assumptions about struct layout.
16895 These assumptions hold on all porting targets that I know of, but
16896 they are not guaranteed, they're easy to remove, and removing them
16897 makes further changes easier.
16899 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
16900 This doesn't fix a bug but makes the code clearer.
16901 (string_overrun_cookie): Now const. Use initializers that
16902 don't formally overflow signed char, to avoid warnings.
16903 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
16904 can cause Emacs to crash when string overrun checking is enabled.
16905 (allocate_buffer): Don't assume sizeof (struct buffer) is a
16906 multiple of sizeof (EMACS_INT); it need not be, if
16907 alignof(EMACS_INT) < sizeof (EMACS_INT).
16908 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
16910 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
16912 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
16914 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>

17682 DEFUN now defines a static function. To make the function external
17683 so that it can be used in other C modules, use the new macro DEFUE.

17769 * xdisp.c (redisplay_window): Don't try to determine the character
17770 position of the scroll margin if the window start point w->startp
17771 is outside the buffer's accessible region. (Bug#8468)
17773 2011-04-10 Eli Zaretskii <eliz@gnu.org>
17775 Fix write-region and its subroutines for buffers > 2GB.
17776 * fileio.c (a_write, e_write): Modify declaration of arguments and

17787 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>

17807 not the number of arguments given. This is simpler and lets GCC
17808 4.6.0 generate slightly better code.
17810 * ftfont.c: Distingish more carefully between FcChar8 and char.
17811 The previous code passed unsigned char * to a functions like
17812 strlen and xstrcasecmp that expect char *, which does not
17813 conform to the C standard.
17814 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
17815 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
17816 char * when the C standard requires it.
17818 * keyboard.c (read_char): Remove unused var.
17820 * eval.c: Port to Windows vsnprintf (Bug#8435).
17821 Include <limits.h>.
17822 (SIZE_MAX): Define if the headers do not.
17823 (verror): Do not give up if vsnprintf returns a negative count.
17824 Instead, grow the buffer. This ports to Windows vsnprintf, which
17825 does not conform to C99. Problem reported by Eli Zaretskii.
17826 Also, simplify the allocation scheme, by avoiding the need for
17827 calling realloc, and removing the ALLOCATED variable.
17829 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
17831 Remove invocations of doprnt, as Emacs now uses vsnprintf.
17832 But keep the doprint source code for now, as we might revamp it
17833 and use it again (Bug#8435).
17834 * lisp.h (doprnt): Remove.
17835 * Makefile.in (base_obj): Remove doprnt.o.
17836 * deps.mk (doprnt.o): Remove.
17838 error: Print 32- and 64-bit integers portably (Bug#8435).
17839 Without this change, on typical 64-bit hosts error ("...%d...", N)
17840 was used to print both 32- and 64-bit integers N, which relied on
17841 undefined behavior.
17842 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
17843 * lisp.h (error, verror): Mark as printf-like functions.
17844 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
17845 Report overflow in size calculations when allocating printf buffer.
17846 Do not truncate output string at its first null byte.
17847 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
17848 Truncate the output at a character boundary, since vsnprintf does not
17850 * charset.c (check_iso_charset_parameter): Convert internal
17851 character to string before calling 'error', since %c now has the
17853 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
17854 overflow when computing char to be passed to 'error'. Do not
17855 pass Lisp_Object to 'error'; pass the integer instead.
17856 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
17857 formatted with plain %d.
17859 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
17861 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
17863 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
17865 * xterm.c (x_catch_errors): Remove duplicate declaration.
17867 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
17869 * xdisp.c, lisp.h (message_nolog): Remove; unused.
17871 2011-04-10 Jim Meyering <meyering@redhat.com>
17873 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
17874 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
17875 return ssize_t not "int", and use size_t as the buffer length.
17876 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
17877 * gnutls.h: Update declarations.
17878 * process.c (read_process_output): Use ssize_t, to match.
17879 (send_process): Likewise.
17881 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
17883 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
17885 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
17887 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
17888 Use unsigned char, to match FcChar8 type definition.
17890 * xterm.c (handle_one_xevent):
17891 * xmenu.c (create_and_show_popup_menu):
17892 * xselect.c (x_decline_selection_request)
17893 (x_reply_selection_request): Avoid type-punned deref of X events.
17895 2011-04-09 Eli Zaretskii <eliz@gnu.org>
17897 Fix some uses of `int' instead of EMACS_INT.
17898 * search.c (string_match_1, fast_string_match)
17899 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
17900 (scan_buffer, find_next_newline_no_quit)
17901 (find_before_next_newline, search_command, Freplace_match)
17902 (Fmatch_data): Make some `int' variables be EMACS_INT.
17904 * xdisp.c (display_count_lines): 3rd argument and return value now
17905 EMACS_INT. All callers changed.
17906 (pint2hrstr): Last argument is now EMACS_INT.
17908 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
17909 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
17910 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
17911 (decode_coding_utf_16, decode_coding_emacs_mule)
17912 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
17913 (decode_coding_ccl, decode_coding_charset)
17914 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
17915 (decode_coding_iso_2022, decode_coding_emacs_mule)
17916 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
17917 <char_offset, last_offset>: Declare EMACS_INT.
17918 (encode_coding_utf_8, encode_coding_utf_16)
17919 (encode_coding_emacs_mule, encode_invocation_designation)
17920 (encode_designation_at_bol, encode_coding_iso_2022)
17921 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
17922 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
17924 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
17925 (encode_invocation_designation): Last argument P_NCHARS is now
17927 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
17928 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
17930 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
17933 * ccl.c (Fccl_execute_on_string): Declare some variables
17936 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
17938 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
17940 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
17942 * process.c (Fformat_network_address): Doc fix.
17944 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
17946 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
17948 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
17950 * keyboard.c (read_char): Call Lisp function help-form-show,
17951 instead of using internal_with_output_to_temp_buffer.
17952 (Qhelp_form_show): New var.
17953 (syms_of_keyboard): Use DEFSYM macro.
17955 * print.c (internal_with_output_to_temp_buffer): Function deleted.
17957 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
17959 2011-04-06 Chong Yidong <cyd@stupidchicken.com>

17968 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
17970 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
17972 Fix more problems found by GCC 4.6.0's static checks.

17976 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
17978 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
17980 * xdisp.c (vmessage): Mark as a printf-like function.
17982 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
17984 * sound.c (sound_warning): Don't crash if arg contains a printf format.

17988 (tiff_load): Add casts to remove these marks before passing them
17989 to system-supplied API.
17991 * eval.c (Fsignal): Remove excess argument to 'fatal'.
17993 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
17994 This avoids several warnings with gcc -Wstrict-overflow.
17995 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
17996 directly, rather than having caller test rule sign. This avoids
17997 some unnecessary tests.
17998 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
17999 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
18000 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
18002 * xfont.c (xfont_text_extents): Remove var that was set but not used.
18003 (xfont_open): Avoid unnecessary tests.
18005 * composite.c (composition_gstring_put_cache): Use unsigned integer.
18007 * composite.h, composite.c (composition_gstring_put_cache):
18008 Use EMACS_INT, not int, for length.
18010 * composite.h (COMPOSITION_DECODE_REFS): New macro,
18011 breaking out part of COMPOSITION_DECODE_RULE.
18012 (COMPOSITION_DECODE_RULE): Use it.
18013 * composite.c (get_composition_id): Remove unused local vars,
18014 by using the new macro.
18016 * textprop.c (set_text_properties_1): Change while to do-while,
18017 since the condition is always true at first.
18019 * intervals.c (graft_intervals_into_buffer): Mark var as used.
18020 (interval_deletion_adjustment): Return unsigned value.
18023 * process.c (list_processes_1, create_pty, read_process_output):
18024 (exec_sentinel): Remove vars that were set but not used.
18025 (create_pty): Remove unnecessary "volatile"s.

18033 (update_syntax_table): Use unsigned instead of int.
18035 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
18036 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
18037 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
18039 * print.c (print_error_message): Avoid int overflow.
18041 * font.c (font_list_entities): Redo for clarity,
18042 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
18044 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
18045 (font_score): Avoid potential overflow in diff calculation.
18047 * fns.c (substring_both): Remove var that is set but not used.
18048 (sxhash): Redo loop for clarity and to avoid wraparound warning.
18050 * eval.c (funcall_lambda): Rename local to avoid shadowing.
18052 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
18053 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
18054 can always succeed if overflow has undefined behavior.
18056 * search.c (boyer_moore, wordify): Remove vars set but not used.
18057 (wordify): Omit three unnecessary tests.
18059 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
18060 All callers changed. This avoids the need for an unused var.
18062 * casefiddle.c (casify_region): Remove var that is set but not used.
18064 * dired.c (file_name_completion): Remove var that is set but not used.
18066 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
18068 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
18069 (Finsert_file_contents): Remove unnecessary code checking fd.
18071 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
18072 Check for integer overflow on size calculations.
18074 * buffer.c (Fprevious_overlay_change): Remove var that is set
18077 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
18078 Remove vars that are set but not used.
18079 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
18080 (timer_check_2): Mark vars as initialized.
18082 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
18084 * image.c (lookup_image): Remove var that is set but not used.
18085 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
18087 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
18088 that are set but not used.
18090 * xfns.c (make_invisible_cursor): Don't return garbage
18091 if XCreateBitmapFromData fails (Bug#8410).
18093 * xselect.c (x_get_local_selection, x_handle_property_notify):
18094 Remove vars that are set but not used.
18096 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
18097 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
18099 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
18100 Remove var that is set but not used.
18101 (scroll_bar_windows_size): Now size_t, not int.
18102 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
18103 Check for overflow.
18105 * xfaces.c (realize_named_face): Remove vars that are set but not used.
18106 (map_tty_color) [!defined MSDOS]: Likewise.
18108 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
18110 * coding.c: Remove vars that are set but not used.
18111 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
18112 All callers changed.
18113 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
18114 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
18115 (decode_coding_charset): Remove vars that are set but not used.
18117 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
18118 that is set but not used.
18120 * print.c (print_object): Remove var that is set but not used.
18122 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
18123 The gnulib version avoids calling malloc in the usual case,
18124 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
18125 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
18126 * filelock.c (current_lock_owner): Likewise.
18127 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
18128 * sysdep.c: Include allocator.h, careadlinkat.h.
18129 (emacs_no_realloc_allocator): New static constant.
18130 (emacs_readlink): New function.
18131 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
18132 ../lib/careadlinkat.h.
18134 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
18136 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
18137 first non-nil return value).
18139 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
18141 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
18142 if not defined (Bug#8403).

18146 * xdisp.c (display_count_lines): Remove parameter `start',
18147 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.

18151 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
18152 and thereabouts. All callers changed.
18153 (get_per_char_metric): Remove parameter `f', unused since
18154 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
18156 2011-04-02 Jim Meyering <meyering@redhat.com>
18158 do not dereference NULL upon failed strdup
18159 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
18160 (ns_get_family): Likewise.
18162 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
18164 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
18166 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
18168 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
18171 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
18173 Add lexical binding.
18175 * window.c (Ftemp_output_buffer_show): New fun.
18176 (Fsave_window_excursion):
18177 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
18179 * lread.c (lisp_file_lexically_bound_p): New function.

18184 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
18186 (syms_of_lread): Declare `lexical-binding'.
18188 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
18190 * keyboard.c (eval_dyn): New fun.
18191 (menu_item_eval_property): Use it.
18193 * image.c (parse_image_spec): Use Ffunctionp.
18195 * fns.c (concat, mapcar1): Accept byte-code-functions.
18197 * eval.c (Fsetq): Handle lexical vars.
18198 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
18199 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
18200 (FletX, Flet): Obey lexical binding.
18201 (Fcommandp): Handle closures.
18202 (Feval): New `lexical' arg.
18203 (eval_sub): New function extracted from Feval. Use it almost
18204 everywhere where Feval was used. Look up vars in lexical env.
18206 (Ffunctionp): Move from subr.el.
18207 (Ffuncall): Handle closures.
18208 (apply_lambda): Remove `eval_flags'.
18209 (funcall_lambda): Handle closures and new byte-code-functions.
18210 (Fspecial_variable_p): New function.
18211 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
18212 but without exporting it to Lisp.
18214 * doc.c (Fdocumentation, store_function_docstring):
18215 * data.c (Finteractive_form): Handle closures.
18217 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
18220 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
18222 (exec_byte_code): New function extracted from Fbyte_code to handle new
18223 calling convention for byte-code-functions. Add new byte-codes.
18225 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
18227 * alloc.c (Fmake_symbol): Init new `declared_special' field.
18229 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
18231 * xdisp.c (redisplay_internal): Fix prototype.
18233 2011-03-31 Eli Zaretskii <eliz@gnu.org>
18235 * xdisp.c (SCROLL_LIMIT): New macro.
18236 (try_scrolling): Use it when setting scroll_limit.
18237 Limit scrolling to 100 screen lines.
18238 (redisplay_window): Even when falling back on "recentering",
18239 position point in the window according to scroll-conservatively,
18240 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
18242 (try_scrolling): When point is above the window, allow searching
18243 as far as scroll_max, or one screenful, to compute vertical
18244 distance from PT to the scroll margin position. This prevents
18245 try_scrolling from unnecessarily failing when
18246 scroll-conservatively is set to a value slightly larger than the
18247 window height. Clean up the case of PT below the margin at bottom
18248 of window: scroll_max can no longer be INT_MAX. When aggressive
18249 scrolling is in use, don't let point enter the opposite scroll
18250 margin as result of the scroll.
18251 (syms_of_xdisp) <scroll-conservatively>: Document the
18252 threshold of 100 lines for never-recentering scrolling.
18254 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
18256 * dispextern.h (move_it_by_lines):

18259 (message_log_check_duplicate): Remove parameters `prev_bol' and
18260 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
18261 (redisplay_internal): Remove parameter `preserve_echo_area',
18262 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
18264 * indent.c (Fvertical_motion):
18265 * window.c (window_scroll_pixel_based, Frecenter):
18266 Don't pass `need_y_p' to `move_it_by_lines'.
18268 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
18270 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
18271 steal a few bits to be more compact.
18272 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
18273 Remove unneeded casts.
18275 * bytecode.c (Fbyte_code): CAR and CDR can GC.
18277 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
18279 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
18280 binding" message (bug#7967).
18282 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
18284 Fix more problems found by GCC 4.6.0's static checks.
18286 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
18287 Remove unused local var.
18289 * editfns.c (Fmessage_box): Remove unused local var.
18291 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
18292 (note_mode_line_or_margin_highlight, note_mouse_highlight):
18293 Omit unused local vars.
18294 * window.c (shrink_windows): Omit unused local var.
18295 * menu.c (digest_single_submenu): Omit unused local var.
18296 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
18297 Omit unused local var.
18299 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
18300 Don't assume string length fits in int.
18301 (keyremap_step, read_key_sequence): Use size_t for sizes.
18302 (read_key_sequence): Don't check last_real_key_start redundantly.
18304 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
18305 instead of alloca (Bug#8344).
18307 * eval.c (Fbacktrace): Don't assume nargs fits in int.
18308 (Fbacktrace_frame): Don't assume nframes fits in int.
18310 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
18312 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
18315 * term.c (produce_glyphless_glyph): Remove unnecessary test.
18317 * cm.c (calccost): Turn while-do into do-while, for clarity.
18319 * keyboard.c (syms_of_keyboard): Use the same style as later
18320 in this function when indexing through an array. This also
18321 works around GCC bug 48267.
18323 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
18325 * xselect.c (x_check_property_data): Return correct size (Bug#8335).

18328 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
18330 * keyboard.c, keyboard.h (num_input_events): Now size_t.
18331 This avoids undefined behavior on integer overflow, and is a bit
18332 more convenient anyway since it is compared to a size_t variable.
18334 Variadic C functions now count arguments with size_t, not int.
18335 This avoids an unnecessary limitation on 64-bit machines, which
18336 caused (substring ...) to crash on large vectors (Bug#8344).
18337 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
18338 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

18344 (internal_condition_case_n, run_hook_with_args, apply_lambda)
18345 (funcall_lambda, mark_backtrace): Likewise.
18346 * fns.c (concat): Likewise.
18347 * frame.c (x_set_frame_parameters): Likewise.
18348 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
18349 0 if not found, not -1. All callers changed.
18351 * alloc.c (garbage_collect): Don't assume stack size fits in int.
18352 (stack_copy_size): Now size_t, not int.
18353 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

18358 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
18359 All callers changed.
18361 * lisp.h (multibyte_char_to_unibyte):
18362 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
18363 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

18365 * cmds.c (internal_self_insert):
18366 * editfns.c (general_insert_function):
18367 * keymap.c (push_key_description):
18368 * search.c (Freplace_match):
18369 * xdisp.c (message_dolog, set_message_1): All callers changed.
18371 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
18373 * keyboard.c (safe_run_hook_funcall): New function.
18374 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
18375 don't set the hook to nil, but remove the offending function instead.
18376 (Qcommand_hook_internal): Remove, unused.
18377 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
18378 Vcommand_hook_internal.
18380 * eval.c (enum run_hooks_condition): Remove.
18381 (funcall_nil, funcall_not): New functions.
18382 (run_hook_with_args): Call each function through a `funcall' argument.
18383 Remove `cond' argument, now redundant.
18384 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
18385 (Frun_hook_with_args_until_failure): Adjust accordingly.
18386 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
18388 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
18390 * dispextern.h (string_buffer_position): Remove declaration.
18392 * print.c (strout): Remove parameter `multibyte', unused since
18393 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
18395 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
18396 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
18397 All callers changed.
18399 * w32.c (_wsa_errlist): Use braces for struct initializers.

18402 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
18403 All callers changed.

18405 used outside xdisp.c).
18406 (cursor_row_p): Remove parameter `w', unused since
18407 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

18409 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
18410 All callers changed.
18412 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
18414 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

18425 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
18427 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>

18443 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
18445 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
18447 * w32.c (read_unc_volume): Use parameter `henum', instead of
18448 global variable `wget_enum_handle'.
18450 * keymap.c (describe_vector): Remove parameters `indices' and
18451 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

18466 * gtkutil.c (xg_maybe_add_timer):
18467 * keyboard.c (readable_events):
18468 * process.c (wait_reading_process_output):
18469 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
18471 * insdel.c (adjust_markers_gap_motion):
18472 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.

18548 * term.c (Fsuspend_tty, Fresume_tty):
18549 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
18550 * window.c (temp_output_buffer_show):

18555 * editfns.c (save_excursion_restore):
18556 * cmds.c (internal_self_insert):
18557 * callint.c (Fcall_interactively):
18558 * buffer.c (Fkill_all_local_variables):
18559 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
18561 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
18562 unconditionally since it does the check itself.
18564 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
18566 Fix more problems found by GCC 4.5.2's static checks.
18568 * coding.c (encode_coding_raw_text): Avoid unnecessary test
18569 the first time through the loop, since we know p0 < p1 then.
18570 This also avoids a gcc -Wstrict-overflow warning.
18572 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
18573 leading to a memory leak, possible in functions like
18574 load_charset_map_from_file that can allocate an unbounded number
18575 of objects (Bug#8318).
18577 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
18578 that could (at least in theory) be that large.
18580 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
18581 This is less likely to overflow, and avoids undefined behavior if
18582 overflow does occur. All callers changed. Use strtoul to scan
18583 for the unsigned long integer.
18584 (pint2hrstr): Simplify and tune code slightly.
18585 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

18600 * process.c (Fmake_network_process): Use socklen_t, not int,
18601 where POSIX says socklen_t is required in portable programs.
18602 This fixes a porting bug on hosts like 64-bit HP-UX, where
18603 socklen_t is wider than int (Bug#8277).
18604 (Fmake_network_process, server_accept_connection):
18605 (wait_reading_process_output, read_process_output):
18608 * process.c: Rename or move locals to avoid shadowing.
18609 (list_processes_1, Fmake_network_process):
18610 (read_process_output_error_handler, exec_sentinel_error_handler):
18611 Rename or move locals.
18612 (Fmake_network_process): Define label "retry_connect" only if needed.
18613 (Fnetwork_interface_info): Fix pointer signedness.

18615 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
18616 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
18618 Make tparam.h and terminfo.c consistent.
18619 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
18620 Include tparam.h instead, since it declares them.
18621 * cm.h (PC): Remove extern decl; tparam.h now does this.
18622 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
18623 * terminfo.c: Include tparam.h, to check interfaces.
18624 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
18625 (tparam): Adjust signature to match interface in tparam.h;
18626 this removes some undefined behavior. Check that outstring and len
18627 are zero, which they always are with Emacs.
18628 * tparam.h (PC, BC, UP): New extern decls.
18630 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
18631 (xftfont_open): Rename locals to avoid shadowing.
18633 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
18634 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
18635 (OTF_TAG_SYM): Omit macro if not needed.
18636 (ftfont_list): Remove unused local.
18637 (get_adstyle_property, ftfont_pattern_entity):
18638 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
18639 Rename locals to avoid shadowing.
18641 * xfont.c (xfont_list_family): Mark var as initialized.
18643 * xml.c (make_dom): Now static.
18645 * composite.c (composition_compute_stop_pos): Rename local to
18647 (composition_reseat_it): Remove unused locals.
18648 (find_automatic_composition, composition_adjust_point): Likewise.
18649 (composition_update_it): Mark var as initialized.
18650 (find_automatic_composition): Mark vars as initialized,
18651 with a FIXME (Bug#8290).
18653 character.h: Rename locals to avoid shadowing.
18654 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
18655 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
18656 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
18657 (BUF_DEC_POS): Be more systematic about renaming local temporaries
18658 to avoid shadowing.
18660 * textprop.c (property_change_between_p): Remove; unused.
18662 * intervals.c (interval_start_pos): Now static.
18664 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
18666 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
18667 Rename locals to avoid shadowing.
18669 * sound.c (wav_play, au_play, Fplay_sound_internal):
18670 Fix pointer signedness.
18671 (alsa_choose_format): Remove unused local var.
18672 (wav_play): Initialize a variable to 0, to prevent undefined
18673 behavior (Bug#8278).
18675 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
18677 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
18679 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
18680 clobbering (Bug#8298).
18681 * sysdep.c (sys_subshell): Likewise.
18682 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
18684 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
18685 This should get cleaned up, so that child_setup has the
18686 same signature on all platforms.
18688 * callproc.c (call_process_cleanup): Now static.
18689 (relocate_fd): Rename locals to avoid shadowing.
18691 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
18693 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
18694 not to be necessary, and produces flickering.
18696 2011-03-20 Glenn Morris <rgm@gnu.org>
18698 * config.in: Remove file.
18700 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
18702 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
18703 are now in src/globals.h.
18704 (syms_of_minibuf): Remove spurious & from previous change.

18858 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
18859 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
18860 to use the following functions instead of these macros.
18861 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
18862 EMACS_INT, since callers assume the returned value fits in int.
18863 (upcase1): Likewise, for UPCASE_TABLE.
18864 (uppercasep, lowercasep, upcase): New static inline functions.
18865 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

18875 (regex_compile, re_match_2_internal): Mark locals as initialized.
18876 (RETALLOC_IF): Define only if needed.
18877 (WORDCHAR_P): Likewise. This one is never needed, but is used
18878 only in a comment talking about a compiler bug, so put inside
18879 the #if 0 of that comment.
18880 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
18881 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

18907 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
18908 New macros, so that the caller can use some names other than
18909 gcpro1, gcpro2, etc.
18910 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
18912 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
18913 argument, for consistency with GCPRO2_VAR, etc: it is now the
18914 prefix of the variable, not the variable itself. All uses
18916 * dired.c (directory_files_internal, file_name_completion):
18917 Rename locals to avoid shadowing.
18919 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
18920 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
18921 dired.c's scmp function, had undefined behavior.
18922 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
18923 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
18924 * buffer.h: ... to here, because these macros use current_buffer,
18925 and the new implementation with inline functions needs to have
18926 current_buffer in scope now, rather than later when the macros
18928 (downcase, upcase1): New static inline functions.
18929 (DOWNCASE, UPCASE1): Reimplement using these functions.
18930 This avoids undefined behavior in expressions like
18931 DOWNCASE (x) == DOWNCASE (y), which previously suffered
18932 from race conditions in accessing the global variables
18933 case_temp1 and case_temp2.
18934 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
18935 * lisp.h (case_temp1, case_temp2): Remove their decls.
18936 * character.h (ASCII_CHAR_P): Move from here ...
18937 * lisp.h: ... to here, so that the inline functions mentioned
18938 above can use them.
18940 * dired.c (directory_files_internal_unwind): Now static.
18942 * fileio.c (file_name_as_directory, directory_file_name):
18943 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
18945 (file_name_as_directory): Use const pointers when appropriate.
18946 (Fexpand_file_name): Likewise. In particular, newdir might
18947 point at constant storage, so make it a const pointer.
18948 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
18949 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
18951 (Fset_file_times, Finsert_file_contents, auto_save_error):

18956 to avoid shadowing.
18958 * marker.c (bytepos_to_charpos): Remove; unused.
18960 * lisp.h (verify_bytepos, count_markers): New decls,
18961 so that gcc does not warn that these functions aren't declared.
18963 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
18964 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
18965 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
18966 (copy_text): Remove unused local var.
18968 * filelock.c (within_one_second): Now static.
18969 (lock_file_1): Rename local to avoid shadowing.
18971 * buffer.c (fix_overlays_before): Mark locals as initialized.
18972 (fix_start_end_in_overlays): Likewise. This function should be
18973 simplified by using pointers-to-pointers, but that's a different
18975 (switch_to_buffer_1): Now static.
18976 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
18977 (report_overlay_modification): Rename locals to avoid shadowing.
18979 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
18980 Fix pointer signedness issue.
18981 (sys_subshell): Mark local as volatile if checking for lint,
18982 to suppress a gcc -Wclobbered warning that does not seem to be right.
18983 (MAXPATHLEN): Define only if needed.
18985 * process.c (serial_open, serial_configure): Move decls from here ...
18986 * systty.h: ... to here, so that they can be checked.
18988 * fns.c (get_random, seed_random): Move extern decls from here ...
18989 * lisp.h: ... to here, so that they can be checked.
18991 * sysdep.c (reset_io): Now static.
18992 (wait_for_termination_signal): Remove; unused.
18994 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
18995 (copy_keymap_item, append_key, push_text_char_description):
18997 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
18998 (DENSE_TABLE_SIZE): Remove; unused.
18999 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
19000 (describe_map_tree):
19001 Rename locals to avoid shadowing.
19003 * keyboard.c: Declare functions static if they are not used elsewhere.
